EMBODIMENT OF INVENTION

(24) Preferred embodiments of the present invention will be now described in detail with reference to the drawings. Meanwhile, the present invention is not limited to the embodiments as described below, and various modifications thereof can be made as long as having substantially the same configuration as those of the invention and also obtaining the same functions and effects.

Embodiment 1

(25) FIG. 1 is a plan view showing a molded hook and loop fastener according to the present embodiment 1 and FIG. 2 is a perspective view showing a state of the molded hook and loop fastener before a resin material infiltration-blocking member is fixed to a hook and loop fastener member thereof. Also, FIGS. 3 and 5 are sectional views taken a III-III line and a IV-IV line shown in FIG. 1.

(26) Meanwhile, in the following description, a longitudinal direction of a base material of the molded hook and loop fastener is referred to as a front and rear direction and a width direction of the base material is referred to as a right and left direction. Also, a front and back direction of the base material is referred to as an upward and downward direction, and in particular, a direction toward a side on which engaging elements are arranged with respect to the base material is referred to as an upward direction and the opposite direction is referred to as a downward direction.

(27) The molded hook and loop fastener 1 according to the present embodiment 1 includes one hook and loop fastener member 10 having a plurality of engaging elements 12 erected on an upper surface (first surface) of a base material 11 and a resin material infiltration-blocking member 20 fixed to the hook and loop fastener member 10 and having a frame shape.

(28) The hook and loop fastener member 10 includes a flat plate-shaped base material 11, right and left support members 13 erected on the upper surface (first surface) of the base material 11 along the longitudinal direction (front and rear direction) thereof, a plurality of engaging elements (hook-shaped male engaging elements) 12 arranged between the right and left support members 13, two linear magnetic bodies 14 arranged along the front and rear direction, fixation portions 15 arranged on insides of the right and left support members 13 for fixing the linear magnetic bodies 14, and transversal wall bodies 16 arranged along the width direction.

(29) The hook and loop fastener member 10 is formed by molding a thermoplastic resin material using a die wheel as described below. As a material for the hook and loop fastener member 10, a thermoplastic resin material, such as polyethylene, polypropylene, polyester, nylon, polybutylene terephthalate, or copolymer thereof, can be employed. Also, the linear magnetic bodies 14 are integrally fixedly molded on the fixation portions 15 by introducing the linear magnetic bodies 14 into portions where the fixation portions 15 of the hook and loop fastener member 10 are formed when the hook and loop fastener member 10 is molded.

(30) In the present embodiment 1, the base material 11 has a rectangular thin board shape elongated in the front and rear direction (longitudinal direction) as viewed in the upward and downward direction and is configured to be bendable in the upward and downward direction (front and back direction). The base material 11 is arranged in a center region in the width direction and has a center region portion, on which the plurality of engaging elements 12 and the right and left support members 13 are erected, and right and left side edge portions 11a arranged outward in the width direction beyond locations where the right and left support members 13 are erected. Also, upper surfaces (first surface) of the right and left side edge portions 11a of the base material 11 is formed as a flat surface. In addition, right and left side edge ends of the base material 11 are formed to be parallel to each other along the longitudinal direction of the hook and loop fastener member 10.

(31) On a lower surface (back surface) of the base material 11, a plurality of recessed groove portions 11b are provided to be parallel to each other along the front and rear direction. Because the base material 11 has such a plurality of recessed groove portions 11b, when the molded hook and loop fastener 1 is integrally molded with a cushion body (foam body) 6, as described below, upon foaming thereof, a bonded area between the base material 11 of the hook and loop fastener member 10 and the cushion body 6 can be increased, thereby enhancing fixation strength of the hook and loop fastener member 10 to the cushion body 6.

(32) Alternatively, according to the present invention, in order to enhance fixation strength of the hook and loop fastener member 10 to the cushion body 6, instead of the plurality of recessed groove portions 11b as described above, for example, ridges, arrowhead-shaped protrusions or the like may be provided on the lower surface of the base material 11 or a non-woven fabric may be fixed thereto. Also, the lower surface of the base material 11 may be formed as a flat surface without being provided with the recessed groove portions 11b or the like as described above.

(33) The right and left support members 13 are constructed by wall-shaped members erected along the front and rear direction at locations, where are located on the inside of right and left end edges of the base material 11 in the width direction (right and left direction), so that an engaging element region 18 constituted of the plurality of engaging elements 12 is interposed therebetween. Also, the right and left support members 13 are integrally molded with the base material 11.

(34) According to the present embodiment 1, each of the right and left support members 13 has three longitudinal wall rows extending in the longitudinal direction and each of the longitudinal wall rows is constituted of a plurality of longitudinal wall bodies 13a intermittently arranged at a predetermined pitch along the longitudinal direction. Also, longitudinal wall connection portions for connecting longitudinal wall bodies 13a of the longitudinal wall rows, which are adjacent to each other in the width direction, are arranged in each support member 13.

(35) The support member 13 may be any other members so far as the resin material infiltration-blocking member 20 can be supported, but each may preferably be at least one longitudinal wall member (longitudinal wall row) intermittently or continuously extending in the longitudinal direction. Namely, the support member 13 may be, for example, one or more longitudinal wall rows continuously erected along the longitudinal direction or, as described above, longitudinal wall members in which a plurality of longitudinal wall bodies intermittently arranged are arranged in a zigzag shape.

(36) Herein, longitudinal wall bodies 13a of the longitudinal wall row, which is arranged most toward the engaging elements 12, of the support member 13 are referred to as a first row of longitudinal wall bodies 13a, longitudinal wall bodies 13a of the longitudinal wall row, which is arranged outward relative to the first row of longitudinal wall bodies 13a, are referred to as a second row of longitudinal wall bodies 13a, and longitudinal wall bodies 13a of the longitudinal wall row, which is arranged on the outermost side, are referred to as a third row of longitudinal wall bodies 13a. Meanwhile, in the present invention, structures of the right and left support members 13 are not particularly limited, and for example, formation of the longitudinal wall bodies 13a, which constitutes the support members 13 of the present embodiment 1, or the number of arrangement thereof (the number of longitudinal wall rows) may be modified in any other manners.

(37) According to the present embodiment 1, longitudinal wall bodies 13a of each row are intermittently arranged at a predetermined attachment pitch in the longitudinal direction, and gaps are provided between adjacent longitudinal wall bodies 13a of each row in the longitudinal direction. Also, longitudinal wall bodies 13a of the second row are arranged to correspond to locations of gaps formed between adjacent longitudinal wall bodies 13a of the first and third row, so that longitudinal wall bodies 13a of the first to third rows are arranged in a zigzag shape to have a positional relationship that the longitudinal wall rows are offset relative to each other.

(38) Also, the connection portions for longitudinal wall bodies 13a of the support members 13 are arranged between longitudinal wall bodies 13a of the first and third rows and longitudinal wall bodies 13a of the second rows and thus connect front and rear end portions of longitudinal wall bodies 13a of the first and third rows to center portions of longitudinal wall bodies 13a of the second row in the longitudinal direction. A height dimension (dimension in the upward and downward direction) of the connection portions is set to be lower than those of longitudinal wall bodies 13a of the first to third rows, and also a width dimension (dimension in the right and left direction) of the connection portions is set to have the same size as distances between longitudinal wall bodies 13a of the first and third rows and longitudinal wall bodies 13a of the second row in the width direction.

(39) As the support members 13 according to the present embodiment 1 is configured as described above, gaps provided between adjacent longitudinal wall bodies 13a of each longitudinal wall row can be widened or narrowed and therefore the hook and loop fastener member 10 (molded hook and loop fastener 1) can be freely bent in the upward and downward direction.

(40) Also, because the support members 13 are configured to have a plurality of longitudinal wall rows and also to be wide in the width direction, the resin material infiltration-blocking member 20 can be supported widely in the width direction on upper surfaces of the support members 13 when the resin material infiltration-blocking member 20 is fixed to the hook and loop fastener member 10 to be covered on the upper surfaces of the support members 13 as described below, thereby stabilizing a position of the resin material infiltration-blocking member.

(41) Further, when the molded hook and loop fastener 1 is attracted and fixed to a cavity surface (fastener mount surface) 7a of a mold 7 as described below, the resin material infiltration-blocking member 20 can be sandwiched widely in the width direction between the support members 13 and the cavity surface 7a of the mold 7. Accordingly, the resin material infiltration-blocking member 20 can be widely, stably and closely contacted with the upper surface portions of the support members 13, and also the resin material infiltration-blocking member 20 can be widely, stably and closely contacted with the cavity surface 7a of the mold 7. As a result, sealing ability by the resin material infiltration-blocking member 20 (i.e., sealing ability between the hook and loop fastener member 10 and the cavity surface 7a, between which the resin material infiltration-blocking member 20 is sandwiched) can be greatly enhanced.

(42) The engaging elements 12 are erected on the upper surface of the base material 11 to be aligned at a predetermined attachment pitch in the longitudinal direction and the width direction, thereby obtaining an engaging force with respect to a cover material covered on the cushion body 6. In particular, in the case of the present embodiment 1, longitudinal rows of engaging elements 12 aligned along the longitudinal direction are arranged to be arrayed in five rows in the width direction between the right and left support members 13.

(43) In this case, the engaging element region 18 in the hook and loop fastener member 10 is formed by a portion surrounded by the right and left support members 13, a transversal support portion 16a, which is constituted together with the engaging elements 12 by transversal wall bodies 16 arranged on the front-most side as described below, and a transversal support portion 16a, which is constituted together with the engaging elements 12 by transversal wall bodies 16 arranged on the rear-most side.

(44) Also, each engaging element 12 has an erection portion perpendicularly erected from the upper surface of the base material 11 and a hook-shaped engaging head portion branched and curved in the front and rear direction at an upper end of the erection portion. In addition, a height dimension (dimension in the upward and downward direction) of each engaging element 12 as measured from the upper surface of the base material 11 is set to have the same size as a height dimension (height dimension of the longitudinal wall bodies 13a) of the support members 13. Meanwhile, in the present invention, a shape, a dimension, an installing pitch and the like of the engaging elements 12 are not particularly limited and thus can be modified in any other manners.

(45) The transversal wall bodies 16 are erected along the width direction between the support members 13 and the engaging elements 12 and also between engaging elements 12 adjacent to each other in the width direction. In this case, the transversal wall bodies 16 are connected with engaging elements 12, which are arranged to be adjacent thereto, via a lower end portion (end portion located toward the base material 11) thereof (see FIGS. 3 and 4). As the transversal wall bodies 16 and the engaging elements 12 are connected with each other in this way, the transversal wall bodies 16 and the engaging elements 12 are configured to reinforce each other. Alternatively, according to the present invention, the transversal wall bodies 16 and the engaging elements 12 may be formed to be spaced from each other.

(46) Also, a plurality of transversal wall bodies, which are arranged along the width direction on the front-most and rear-most sides of the hook and loop fastener member 10, together with engaging elements 12, which are arranged to be sandwiched between the transversal wall bodies 16, constitutes the transversal support portions 16a for supporting a back side of a transversal frame portion (second frame portion) 22, as described below, of the resin material infiltration-blocking member 20 along the width direction.

(47) In addition, a height dimension of each transversal wall body 16 as measured from the upper surface of the base material 11 is set to have the same size as height dimensions of the longitudinal wall bodies 13a and the engaging elements 12. Namely, in the present embodiment 1, upper ends of the longitudinal wall bodies 13a, the transversal wall bodies 16 and the engaging elements 12 are arranged on the same plane. Accordingly, when longitudinal frame portions (first frame portion) 21 and transversal frame portions (second frame portion) 22 of the resin material infiltration-blocking member 20 as described below are mounted on upper end surfaces of the support members 13 and upper end surfaces of the transversal wall bodies 16a, height positions of each mounted portion of the resin material infiltration-blocking member 20 can be matched (coincided) with each other.

(48) Thus, when the molded hook and loop fastener 1 of the present embodiment 1 is mounted, for example, on a flat cavity surface 7a of the molding mold 7 so that the engaging elements 12 are oriented toward a direction away from the cavity surface 7a (see FIG. 5), the longitudinal frame portion 21 and the transversal frame portion 22 of the resin material infiltration-blocking member 20 can be stably and closely contacted with the cavity surface 7a, thereby preventing a gap from being formed between the cavity surface 7a and the hook and loop fastener member 10, between which the resin material infiltration-blocking member 20 is sandwiched.

(49) The linear magnetic bodies 14 are fixed in the engaging element region 18 of the hook and loop fastener member 10 along rows of engaging elements 12, which are arranged to be closest to the right and left support members 13, while interposing the fixation portions 15 arranged on the upper surface of the base material 11. The linear magnetic bodies 14 have a circular cross-section and are constructed of magnetically attracted or attracting materials.

(50) Because the linear magnetic bodies 14 are arranged on the molded hook and loop fastener 1, when the cushion body 6 is molded using the mold 7 having magnets 8 arranged on the cavity surface 7a or on the vicinity of the cavity surface 7a as described below, a magnetic force generated between the magnets 8 of the mold 7 and the linear magnetic bodies 14 of the molded hook and loop fastener 11 can be used to stably suck and fix the molded hook and loop fastener 1 to the cavity surface 7a of the mold 7.

(51) In this cast, as magnetically attracted materials for the linear magnetic bodies 14, monofilaments, in which magnetic particles made of alloys of iron, cobalt, nickel or the like are mixed to a synthetic resin such as polyester, twisted metal yarns, in which a number of fine metal wires made of such alloys are bundled and twisted, or the like can be used. On the other hand, as magnetically attracting materials for the linear magnetic bodies 14, magnetized wire materials, particularly, linear metal linear magnets, rubber magnets, which are magnetized by mixing magnetic iron oxide to rubber, or the like can be used. Also, according to the present invention, fine tape-shaped magnetic bodies may be used instead of linear magnetic bodies.

(52) The fixation portions 15 for fixing the linear magnetic bodies 14 to the base material 11 are arranged inside of and in the vicinity of the support members 13 to extend along the longitudinal direction with a predetermined space and are configured to protrude in a rectangular cross-sectioned block shape from the upper surface of the base material 11. The linear magnetic bodies 14 are embedded in the fixation portion 15 to extend through the fixation portions 15 along the longitudinal direction. Also, each of the fixation portions 15 is integrally constructed with the engaging elements 12 and the transversal wall bodies 16 erected from the base material 11.

(53) Alternatively, according to the present invention, for example, the fixation portions 15 may be arranged on the lower surface of the base material 11 so that the linear magnetic bodies 14 are fixed to the lower surface of the base material 11. Also, instead of fixing the linear magnetic bodies 14 to the base material 11, a magnetic property may be imparted to the hook and loop fastener member 10 by mixing or kneading magnetic particles to a synthetic resin constructing the hook and loop fastener member 10.

(54) The resin material infiltration-blocking member 20 fixed to the hook and loop fastener member 10 is constructed of a flexible thin piece-shaped sheet member, and in particular the resin material infiltration-blocking member 20 according to the present embodiment 1 is constructed of a non-woven fabric having a predetermined thickness. Because the resin material infiltration-blocking member 20 is constructed of a non-woven fabric, suitable flexibility, pliability and swollen feeling can be imparted to the resin material infiltration-blocking member 20.

(55) Accordingly, in a foaming process of the cushion body 6 as described below, when the resin material infiltration-blocking member 20 is attracted and fixed to the cavity surface 7a of the mold 7 using a magnetic force, the resin material infiltration-blocking member 20 having flexibility or pliability can be properly deformed so that sealing ability between the resin material infiltration-blocking member 20 and the cavity surface 7a of the mold 7 can be enhanced. Alternatively, according to the present invention, the material of the resin infiltration-blocking member 20 is not limited thereto, and thus the resin material infiltration-blocking member 20 may be constructed, for example, of a knitted or woven thin cloth piece or the like.

(56) Also, as shown in FIGS. 1 and 2, the resin material infiltration-blocking member 20 of the present embodiment 1 is constructed of a frame-shaped single sheet member. Namely, the resin material infiltration-blocking member 20 integrally has right and left longitudinal frame portions (first frame portions) 21 arranged along the longitudinal direction of the molded hook and loop fastener 1 and transversal frame portions (second frame portions) 22 arranged along the width direction to correspond to locations of front and rear end portions of the hook and loop fastener member 10 and configured to connect the right and left longitudinal frame portions 21 with each other, and also a rectangular opening portion 23 is formed in a center portion of the resin material infiltration-blocking member 20, which is surrounded by the right and left longitudinal frame portions 21 and the front and rear transversal frame portions 22.

(57) This frame-shaped resin material infiltration-blocking member 20 is fixed to the hook and loop fastener member 10 by bonding or welding back surfaces of the right and left longitudinal frame portions 21 to the right and left side edge portions 11a of the base material 11 of the hook and loop fastener member 10 while protruding inner peripheral edge portions (peripheral edge portion of the opening portion 23) of the right and left longitudinal frame portions 21 and front and rear transversal frame portions 22 of the resin material infiltration-blocking member 20 above upper end locations of the support members 13.

(58) In particular, according to the present embodiment 1, the resin material infiltration-blocking member 10 is fixed to the hook and loop fastener member 10 so that parts of the right and left longitudinal frame portions 21 are covered on the upper surfaces of the support members 13 and also parts of the front and back transversal frame portions 22 are covered on upper surfaces of the transversal support portions 16a arranged on the front-most and rear-most sides of the hook and loop fastener member 10.

(59) At this time, because the right and left longitudinal frame portions 21 of the resin material infiltration-blocking member 20 are supported by the right and left support members 13, the longitudinal frames 21 are hardly collapsed or bend even if a flowing pressure or foaming pressure of a foaming resin material is exerted thereon when the cushion body 6 is foamed as described below. Also, the state where the inner peripheral edge portions of the longitudinal frame portions 21 are protruded above the upper end locations of the support members 13 can be stably kept.

(60) In the present embodiment 1, a length dimension of the resin material infiltration-blocking member 20 (i.e., a dimension of the longitudinal frame portions 21 in the front and rear direction) is set to be larger than a length dimension of the base material 11 of the hook and loop fastener member 10 when the resin material infiltration-blocking member 20 is in a flat state before being attached to the hook and loop fastener member 10. In particular, in the case of the present embodiment 1, even when the resin material infiltration-blocking member 20 is in a state after being fixed to the hook and loop fastener member 10 and thus being partially bent, the resin material infiltration-blocking member 20 is set to have a length dimension larger than that of the base material 11 of the hook and loop fastener member 10.

(61) Also, a width dimension of the resin material infiltration-blocking member 20 (i.e., a dimension between outer side edges of the right and left longitudinal frame portions 21 in the width direction) is set to be larger than a width dimension of the base material 11 of the hook and loop fastener member 10 when the resin material infiltration-blocking member 20 is in a flat state before being attached to the hook and loop fastener member 10. In particular, in the case of the present embodiment 1, even when the resin material infiltration-blocking member 20 is in a state after being fixed to the hook and loop fastener member 10 and thus being partially bent, the resin material infiltration-blocking member 20 is set to have a width dimension larger than that of the base material 11 of the hook and loop fastener member 10.

(62) Namely, when being fixed to the hook and loop fastener member 10, the resin material infiltration-blocking member 20 of the present embodiment 1 has right and left first extension portions 24 extending outward beyond right and left end edges of the base material 11 of the hook and loop fastener member 10 and front and rear second extension portions 25 extending outward beyond front and rear end edges of the base material 11 of the hook and loop fastener member 10.

(63) In addition, the rectangular opening portion 23 formed in the center portion of the resin material infiltration-blocking member 20 has a length dimension smaller than the length dimension of the base material 11 of the hook and loop fastener member 10 and also has a width dimension smaller than a dimension as measured between outer wall surfaces of the right and left support members 13 in the width direction (i.e., a dimension as measured between the left outermost wall surface of the left support member 13 and the right outmost wall surface of the right support member 13 in the width direction).

(64) As the opening portion 23 of the resin material infiltration-blocking member 20 is set to have such a size, a positional offset of the opening portion 23 of the resin material infiltration-blocking member 20 relative to the engaging element region 18 of the hook and loop fastener member 10 can be hardly occurred. In addition, because the positional offset of the opening portion 23 is hardly occurred, it is possible to prevent, for example, parts of engaging elements 12 or support members 13 from protruding (extending) above the resin material infiltration-blocking member 20 from the opening portion 23, and as a result, a close contact ability of the resin material infiltration-blocking member to the cavity surface 7a of the mold 7 upon foaming of the cushion body 6 can be enhanced.

(65) Then, the hook and loop fastener member 10 of the molded hook and loop fastener 1 of the present embodiment 1 having configurations as described above is manufactured, for example, using a manufacturing apparatus as described below.

(66) Specifically, the manufacturing apparatus for the hook and loop fastener member 10, if not shown, includes a die wheel driven to be rotated in one direction, a continuous extruding nozzle for a molten resin arranged to face a peripheral surface of the die wheel, a picking-up roll arranged downstream of the continuous extruding nozzle in a rotation direction of the die wheel to face the peripheral surface of the die wheel, a linear magnetic body supply unit arranged upstream of the continues extruding nozzle in the rotation direction of the die wheel and configured to introduce linear magnetic bodies 14 between facing surfaces of the die wheel and the continuous extruding nozzle, and a cutting unit for cutting a continuous hook and loop fastener member 10, which is peeled off from the peripheral surface of the die wheel, at a predetermined length.

(67) In the peripheral surface of the die wheel equipped in the manufacturing apparatus, molding cavities for molding engaging elements 12, right and left support members 13 and transversal wall bodies 16 and the like of the hook and loop fastener member 10 as described above is formed. Also, the die wheel is configured so that a coolant can flow through the inside of the die wheel, and below the die wheel, a coolant bath is arranged so that a lower half of the die wheel can be dipped therein.

(68) When the hook and loop fastener member 10 of the present embodiment 1 is manufactured using the manufacturing apparatus as described above, a molten resin material is continuously extruded from the continuous extruding nozzle toward the peripheral surface of the die wheel. At this time, because the die wheel is driven to be rotated in one direction, the molten resin extruded on the peripheral surface thereof forms the base material 11 and the like of the hook and loop fastener member 10 by the continuous fastener nozzle and the die wheel, and at the same time successively forms the engaging elements 12, the right and left support members 13, the transversal wall bodies 16 and the like by the molding cavities as described above.

(69) Also, at the same time as when the molten resin material is extruded from the continuous extruding nozzle, the linear magnetic bodies 14 are supplied from the supply unit to an extrusion location of the molten resin to be integrally molded with the continuous hook and loop fastener member 10.

(70) The continuous hook and loop fastener member 10 molded on the peripheral surface of the die wheel is solidified by half-turning while being carried and cooled on the peripheral surface of the die wheel and then is continuously peeled off from the peripheral surface of the die wheel by the picking-up roll.

(71) Then, the continuous hook and loop fastener member 10 (in other words, continuous body of hook and loop fastener member 10) peeled off from the die wheel is conveyed toward the cutting unit and is cut at a predetermined length by the cutting unit. Thus, as shown in FIG. 2, the hook and loop fastener member 10 having the predetermined length is manufactured. Meanwhile, in the present invention, the manufacturing apparatus or manufacturing method for the hook and loop fastener member 10 is not particularly limited and thus can be modified in any other manners.

(72) Subsequently, the frame-shaped resin material infiltration-blocking member 20 is covered on the upper surface of the hook and loop fastener member 10 of the present embodiment 1 manufactured as described above and then is fixed to the right and left side edge portions 11a of the base material 11 of the hook and loop fastener 10, thereby manufacturing the molded hook and loop fastener 1 of the present embodiment 1 as shown in FIG. 1.

(73) At this time, the resin material infiltration-blocking member 20 is attached to the hook and loop fastener member 10 in such a manner that the resin material infiltration-blocking member 20 is covered on the upper surface of the hook and loop fastener member 10 to align a position of the opening portion 23 of the resin material infiltration-blocking member 20 to a position of the engaging element region 18 of the hook and loop fastener member 10 and also lower surfaces (back surfaces) of the right and left longitudinal frame portions 21 of the resin material infiltration-blocking member 20 are fixed to upper surfaces of the right and left side edge portions 11a of the base material 11. In this case, as a means for fixing the longitudinal frame portions 20 of the resin material infiltration-blocking member 20 to the right and left side edge portions 11a of the base material 11, bonding with an adhesive or welding, such as high frequency welding or thermal welding, can be employed.

(74) For example, when a cushion body (foam body) 6 for seats and the like of a vehicle is foamed, the molded hook and loop fastener 1 of the present embodiment 1 using the method as described above is integrated with the cushion body 6 by molding (two-color molding).

(75) Specifically, first, the manufactured molded hook and loop fastener 1, as shown in FIG. 5, is mounted on a fastener mount surface formed at a predetermined location on the cavity surface 7a of the cushion body molding mold 7.

(76) At this time, the fastener mount surface, on which the molded hook and loop fastener 1 is mounted (set), of the cavity surface 7a of the mold 7 is configured as a flat surface, which is a single surface. Alternatively, the fastener mount surface may be configured as a curved surface, which is a convex or concave-shaped single surface. Also, in the interior of the mold 7, magnets 8, such as neodymium magnets, are embedded to correspond to a position of the fastener mount surface on which the molded hook and loop fastener 1 is to be mounted.

(77) Accordingly, the molded hook and loop fastener 1 is mounted so that a surface (upper surface), on which the engaging elements 12 of the base material 11 are formed is oriented to face the fastener mount surface of the mold 7, and thus the linear magnetic bodies 14 arranged in the molded hook and loop fastener 1 are attracted by an attraction force of the magnets 8 so that the molded hook and loop fastener 1 is attracted and fixed to the flat cavity surface (fastener mount surface) 7a of the mold 7.

(78) In this case, particularly, a self-alignment effect, which can automatically precisely align the molded hook and loop fastener 1 to a predetermined position, can be also obtained by using a magnetic force generated between the magnets 8 and the linear magnetic bodies 14 of the molded hook and loop fastener 1.

(79) Also, the molded hook and loop fastener 1 of the present embodiment 1 is held in a state where parts of the resin material infiltration-blocking member 20, particularly parts, which are mounted on upper surfaces of the right and left support members 13 of the hook and loop fastener member 10 and upper surfaces of the transversal support portions 16a constituted of the transversal wall bodies 16 and the engaging elements 12, of the resin material infiltration-blocking member 20, are closely contacted with the flat cavity surface (fastener mount surface) 7a of the mold 7.

(80) Alternatively, in the present invention, the fastener mount surface of the mold 7 may formed in a concave groove shape and the molded hook and loop fastener 1 may be attracted and fixed to the fastener mount surface so that engaging elements 12 or support members of the molded hook and loop fastener 1 are inserted in the concave groove. In this case, parts, which are fixed to the right and left side edge portions of the base material 11, of the resin material infiltration-blocking member 20 can be closely contacted with the cavity surface of the mold 7.

(81) Subsequently, after the molded hook and loop fastener 1 of the present embodiment 1 is attracted and fixed to a predetermined position (fastener mount surface) on the cavity surface 7a of the mold 7 as described above, a foaming resin material is sprayed and injected into the interior of the mold 7 from a spraying nozzle, not shown. At this time, for example, by spraying the foaming resin material while moving the spraying nozzle relative to the mold 7, the foaming resin material can be injected throughout the cavity space of the mold 7. In addition, after a predetermined amount of the foaming resin material is sprayed from the spraying nozzle, the mold 7 is clamped. Thus, as the foaming resin material is foamed to be widely expanded throughout the entire cavity space of the mold, the cushion body 6 is molded.

(82) At this time, because the molded hook and loop fastener 1 is positioned and fixed to the predetermined position by attraction action of the magnets 8 embedded in the mold 7, there is no case where the position of the molded hook and loop fastener 1 is displaced due to a flowing pressure or foaming pressure of the foaming resin material or the like.

(83) Also, because the resin material infiltration-blocking member 20 of the molded hook and loop fastener 1 of the present embodiment 1 is configured so that an upper end portion thereof protruding above upper end locations of the support members 13 is sandwiched between the supper members 13 and the cavity surface 7a of the mold 7 and is more closely contacted with the cavity surface 7a of the mold 7 in the front and rear direction and the right and left direction than that in the engaging element region 18 formed in the hook and loop fastener member 10, a gap, which could allow the foaming resin material to pass therethrough, is not formed between the hook and loop fastener member 10 and the cavity surface 7a, between which the resin material infiltration-blocking member 20 is interposed.

(84) In particular, in the present embodiment 1, as described above, because each support member is constructed widely in the width direction by three longitudinal wall rows, the resin material infiltration-blocking member 20 can be sandwiched widely in the width direction between the support members 13 and the cavity surface 7a of the mold 7. Accordingly, an enhanced sealing ability between the hook and loop fastener member 10 and the cavity surface 7a can be ensured by sandwiching the resin material infiltration-blocking member 20 therebetween.

(85) Also, because the resin material infiltration-blocking member 20 is fixed to the hook and loop fastener member 10 in a state where the right and left longitudinal frame portions 21 are supported by the right and left support members 13, a positional offset of the resin material infiltration member 20 can be prevented even if a flowing pressure or foaming pressure of the foaming resin material is exerted thereon and thus the resin material infiltration-blocking member 20 can be stably kept closely contacted with the cavity surface 7a of the mold 7. Therefore, the engaging element region 18 of the molded hook and loop fastener 1 attracted and fixed to the cavity surface 7a of the mold 7 can be stably blocked from a region exterior of the molded hook and loop fastener (i.e., the cavity space) by the resin material infiltration-blocking member 20.

(86) In particular, in the present embodiment 1, because the resin material infiltration-blocking member 20 is constructed of a non-woven fabric which is pliable and has a proper swollen feeling, even if the cavity surface 7a of the mold 7 has a very small unevenness, the resin material infiltration-blocking member 20 can be securely closely contacted with the cavity surface 7a of the mold 7 by causing the molded hook and loop fastener 1 to be attracted and fixed to the magnets 8, thereby preventing a gap from being formed between the resin material infiltration-blocking member 20 and the cavity surface 7a.

(87) Thus, for example, even if the foaming resin material is strongly collided against the molded hook and loop fastener 1 when the foaming resin material is sprayed from the spraying nozzle, not shown, a flowing pressing or foaming pressure of the foaming resin material is high or the foaming resin material has a low viscosity, it is possible to effectively prevent the foaming material from passing between the resin material infiltration-blocking member 20 and the cavity surface 7a of the mold 7 and then infiltrating into the engaging element region 18 of the molded hook and loop fastener 1.

(88) Therefore, in the engaging element region 18 of the molded hook and loop fastener 1, the engaging elements 12 are not potted with the foaming body, so that the engaging elements 12 can be stably exposed on the upper surface of the base material 11. Accordingly, a predetermined engaging force (fastening force) inherent in the molded hook and loop fastener 1 itself can be stably kept even after foaming of the cushion body 6.

(89) In addition, the molded hook and loop fastener 1 of the present embodiment 1 is configured so that the right and left side edge portions 11 are formed to protrude on right and left outsides of the support members 13 and also the resin material infiltration-blocking member 20 includes right and left first extension portions 24 extending outward beyond right and left end edges of the base material 11 and front and rear second extension portions 25 extending outward beyond front and rear end edges of the base material 11.

(90) Accordingly, when the foaming material is sprayed form the spraying nozzle, the right and left side edge portions 11a of the base material 11 and the first and second extension portions 24 and 25 of the resin material infiltration-blocking member 20 are acted as canopies as described above. As a result, it is possible to prevent the sprayed foaming resin material from being directly strongly hit between the resin material infiltration-blocking member 20 and the cavity surface 7a and also to effectively prevent the foaming resin material from infiltrating into the engaging element region 18.

(91) Then, as the foaming resin material is foamed and solidified in the cavity space of the mold 7 and thus molding is ended, the cushion body 6 integrated with the molded hook and loop fastener 1 of the present embodiment 1 as shown in FIG. 6 can be obtained.

(92) The cushion body 6 with the molded hook and loop fastener 1 manufactured as described above can stably ensure a desired fastening force by a plurality of engaging elements 12 exposed on the upper surface thereof, because the foaming body has not infiltrate into the engaging element region 18 of the molded hook and loop fastener 1. Thus, a surface of the obtained cushion body 6 is covered with a cover material, not shown and then the cover material is pressed toward a location on the cushion body 6, at which the molded hook and loop fastener 1 is attached, and as a result, female engaging elements 12 arranged on a back surface of the cover material can be securely engaged with the engaging elements 12 (male engaging elements) of the molded hook and loop fastener 1. Thus, the cover material can be precisely attached along the surface of the cushion body 6 without being floated from the cushion body 6.

(93) Further, in the molded hook and loop fastener 1 of the present embodiment 1, because the cushion body 6 can be foamed while the molded hook and loop fastener 1 is attracted and fixed to the cavity surface 7a of the mold 7 as described above, it is not necessary to provide a concave groove portion dedicated for positioning and holding the hook and loop fastener on the inner surface of the mold, for example, as in Patent Document 1 as described above. Accordingly, costs or workloads required to manufacture the mold 7 for molding the cushion body 6 can be significantly reduced as compared to the case of Patent Document 1 and thus the cushion body 6 with the molded hook and loop fastener 1 can be efficiently manufactured at low costs.

(94) In addition, in the cushion body 6 with which the molded hook and loop fastener 1 of the present embodiment 1 is integrated, the foaming resin is infiltrated into parts of the resin material infiltration-blocking member 20 made of a non-woven fabric. Also, the first and second extension portions 24 and 25 of the resin material infiltration-blocking member 20 extending from the base material 11 in the molded hook and loop fastener 1 are embedded in the cushion body 6 as shown in FIG. 6. Accordingly, a bonding strength (fixation strength) between the molded hook and loop fastener 1 and the cushion body 6 can be effectively increased, so that the molded hook and loop fastener 1 can be more strongly integrated with the cushion body 6. In this case, the resin material infiltration-blocking member 20, into which the foaming resin is infiltrated, has a semi-rigidity to be bent together with the cushion body 6.

(95) Further, the present embodiment 1 is configured so that in addition to transversal support portions 16a, transversal wall bodies 16 are also arranged between engaging elements 12 in the engaging element region 18 of the molded hook and loop fastener 1. Accordingly, for example, even when the continuous body of hook and loop fastener member 10 molded using the die wheel as described above is cut at any location and thus the hook and loop fastener member 10 having any length is manufactured, a resin material infiltration-blocking member 20 having an opening portion 23, which is adjusted to correspond to the length of the hook and loop fastener member 10, can be prepared and then fixed to the hook and loop fastener member 10, thereby allowing the molded hook and loop fastener 1 of the present embodiment 1 having any length to be simply manufactured.

Embodiment 2

(96) FIG. 7 is a plan view showing a molded hook and loop fastener according to the present embodiment 2 and FIG. 8 is a plan view showing a hook and loop fastener member of the molded hook and loop fastener member. Also, FIGS. 9 and 10 are sectional views taken along a IX-IX line and a line X-X shown in FIG. 7.

(97) Meanwhile, with respect to molded hook and loop fasteners 2 to 5 according to the present embodiment 2 as described below and the following embodiments 3 to 5, configurations different from those of the molded hook and loop fastener 1 of the forgoing embodiment 1 will be primarily described, and thus components and members having substantially the same configurations as those of the molded hook and loop fastener 1 of the foregoing embodiment 1 are designated as the same reference numerals and the descriptions thereof will be omitted.

(98) The molded hook and loop fastener 2 according to the present embodiment 2 includes a plurality of hook and loop fastener members 30 each having a plurality of engaging elements 12 erected on an upper surface (first surface) of a flat plate-shaped base material 31, a monofilament 45 as a connection member for connecting the adjacent hook and loop fastener members 30 with each other in the front and rear direction, and a resin material infiltration-blocking member 40 fixed across the plurality of hook and loop fastener members 30.

(99) Also, each hook and loop fastener member 30 includes a base material 31 having a generally octagonal shape elongated in a longitudinal direction (front and rear direction) thereof as viewed from the front, right and left support members 13 erected on the upper surface (first surface) of the base material 31 along the longitudinal direction, a plurality of engaging elements 12 arranged between the right and left support members 13, two linear magnetic bodies 14 arranged along the front and rear direction, fixation portions (first fixation portions) 15 arranged on insides of the right and left support members 13 for fixing the linear magnetic bodies 14, fixation portions (second fixation portions) 35 for fixing the monofilament 45, which is the connection member, and transversal wall bodies 16 arranged along the width direction.

(100) Meanwhile, in the present embodiment, engaging elements 12, right and left support members 13, linear magnetic bodies 14, fixation portion (first fixation portion) 15 for fixing the linear magnetic bodies 14 and transversal wall bodies 16 are respectively configured in the same manner as those of the forgoing embodiment 1. Also, transversal support portions 16a for support back sides of transversal frame portions (second frame portions) 42, as described above, of the resin material infiltration-blocking member 40 are constituted of a plurality of engaging elements 12 and a plurality of transversal wall bodies 16 arranged along the width direction at the front-most and rear-most side locations of each hook and loop fastener member 20.

(101) The base material 31 in the present embodiment 2 is formed in a thin board shape to be bendable in the upward and downward direction. Also, the base material 31 of each hook and loop fastener member 30 has a center region portion, on which a plurality of engaging elements 12 and the right and left support members 13 are erected, and right and left side edge portions 31a arranged outward in the width direction beyond locations where the right and left support members 13 are erected.

(102) Also, upper surfaces (first surface) of the right and left side edge portions 31a of the base material 31 is formed as a flat surface, and right and left side edge ends of the base material 31 are formed to be parallel to each other along the longitudinal direction of the hook and loop fastener member 30. On a lower surface (back surface) of the base material 31, a plurality of recessed groove portions 31b are provided to be parallel to each other along the front and rear direction.

(103) Further, the base material 31 has front and rear extension portions 31c, which are arranged on front and rear end edge portions of the hook and loop fastener member 30 and from which engaging elements 12 are excluded, and the front and rear extension portions 31c are formed to extend forward and rearward from locations, at which the engaging elements 12 and the transversal wall bodies 16 are arranged, throughout between the right and left support members 13.

(104) Because the right and left side edge portions 31a and the front and rear extension portions 31c are arranged on the base material 31 of each hook and loop fastener member 30 as described above, the right and left side edge portions 31a and the front end rear extension portions 31c serve as canopies against a foaming resin material sprayed from a spraying nozzle upon foaming of a cushion body. Accordingly, it is possible to prevent the sprayed foaming resin material from being directly strongly hit between the resin material infiltration-blocking member 40 and the cavity surface 7a.

(105) An engaging element region 38 of each hook and loop fastener member 30 is formed by a portion, in which a plurality of engaging elements 12 are aligned at a predetermined attachment pitch in the longitudinal direction and the width direction, and the right and left support members 13 are erected along the front and rear direction at locations, which are located on the inside of right and left end edges of the base material 31 in the width direction (right and left direction), so that the engaging element region 38 is sandwiched therebetween.

(106) Like the case of the foregoing embodiment 1, each of right and left support members 13 in the present embodiment 2 has three longitudinal wall rows and each longitudinal wall row is constituted of a plurality of longitudinal wall bodies 13a arranged at a predetermined pitch in the longitudinal direction. Also, longitudinal wall connection portions for connecting longitudinal wall bodies 13a of the longitudinal wall rows, which are adjacent to each other in the width direction, are arranged in each support member 13.

(107) Also, each hook and loop fastener member 30 of the present embodiment is configured so that the second fixation portions 35 for fixing the monofilament 45 is provided to protrude in a rectangular cross-sectioned block shape form the upper surface of the base material 31. The second fixation portions 35 are arranged on a generally center portion, in the width direction, of the base material 31 at a predetermined interval along the longitudinal direction. Also, the second fixation portions 35 are integrally constructed with the engaging elements 12 and the transversal wall bodies 16 erected from the base material 31, thereby reinforcing the engaging elements 12 and the transversal wall bodies 16. The monofilament 45 is embedded in the second fixation portion 35 to extend through the second fixation portions 35 in the longitudinal direction.

(108) Alternatively, in the present invention, the second fixation portions 35 for fixing the monofilament 45 may be constructed as separate bodies from the transversal wall bodies 16. Also, the second fixation portions 35 may be arranged on a lower surface of the base material 31 so that the monofilament 35 is fixed to the lower surface of the base material 31.

(109) In the molded hook and loop fastener 2 of the present embodiment 2, the monofilament 45 is fixed by the block-shaped second fixation portions 35 arranged on each hook and loop fastener member 30, and a connection portion for connecting the adjacent hook and loop fastener members 30 to each other is constructed by a part of the monofilament 35, which are interposed between a second fixation portion 35 arranged on the front-most side of each hook and loop fastener member 30 and a second fixation portion 35 arranged on the rear-most side of another hook and loop fastener member 30 adjacent thereto. In particular, the connection portion formed by the monofilament 45 is fixed to the second fixation portions 35, which are arranged on the generally center portions in the width direction, by a lower surface (back surface) of the resin material infiltration-blocking member 40, thereby connecting the center portions, in the width direction, of the adjacent hook and loop fastener members 30 to each other.

(110) Also, the monofilament 45 in the present embodiment 2 is made of a thermoplastic resin, such as polyester and has flexibility. Also, the monofilament 45 is configured to be bent in a zigzag shape in the right and left direction, and particularly, a bending interval is set so that at least two bent portions having different bending directions are arranged in the part thereof between the second fixation portions 35, which forms the connection portion. In addition, a cross-section of the monofilament 45 has an elliptical shape, which is elongated in a front and back direction of the base material 31 so that the major axis thereof extends along the upward and downward direction.

(111) As the connection portion of the present embodiment 2 is configured as described above, the molded hook and loop fastener 2 having a plurality of hook and loop fastener members 30 can be configured to be easily bent in the width direction due to the connection portion and also to be bent in the front and back direction (see FIG. 12). Meanwhile, in the present invention, a thickness or cross-section shape of the monofilament 45 is not particularly limited, and thus it is sufficient so long as the molded hook and loop fastener 2 is designed to be bendable in the width direction due to the connection portion. Alternatively, in the present invention, the connection member does not need to be constructed by the monofilament 45 as in the present embodiment 2, and thus, for example, a plurality of hook and loop fastener members 30 may be connected to each other by a connection portion integrally molded with the hook and loop fastener members 30 using the same material (the same synthetic resin) as that of the base materials 31.

(112) The resin material infiltration-blocking member 40 of the present embodiment 2 is constructed by a single sheet member made of a thin piece-shaped non-woven fabric having flexibility. Also, the resin material infiltration-blocking member 40 integrally has right and left longitudinal frame portions (first frame portions) 41 continuously arranged over the plurality of hook and loop fastener members 30 and transversal frame portions (second frame portions) 42 arranged in the width direction to bridge between the adjacent hook and loop fastener members 30 and configured to connect the right and left longitudinal frame portions 41 with each other, and a width dimension of the resin material infiltration-blocking member 40 itself is set to have a constant size over the entire length of the resin material infiltration-blocking member 40 in the longitudinal direction thereof. Further, in the resin material infiltration-blocking member 40, rectangular opening portions 43 surrounded by the longitudinal frame portions 41 and the transversal frame portions 42 are formed at a predetermined interval in the longitudinal direction.

(113) In the resin material infiltration-blocking member 40 of the present embodiment 2 having such configurations, parts of the right and left longitudinal frame portions 41 are covered on the upper surfaces of the support members 13, parts of the transversal frame portions 42 are covered on upper surfaces of the transversal support portions 16a arranged on the front-most and rear-most sides of each hook and loop fastener member 30, and then the right and left longitudinal frame portions 41 are fixed to the right and left side edge portions 31a of the base material 31 of each hook and loop fastener member 30 by bonding or welding.

(114) In this case, the width dimension of the resin material infiltration-blocking member 40 (dimension between outer side edges of the right and left longitudinal frame portions 41) is set to have a size of such a degree that the resin material infiltration-blocking member 40 does not protrude (extend out) from the right and left end edges of the base material 31 after being fixed to the hook and loop fastener members 30 and thus being partially bent.

(115) In particular, in the present embodiment 2, the sheet-shaped resin material infiltration-blocking member 40 is configured so that when being fixed to the hook and loop fastener members 30, parts thereof between the plurality of hook and loop fastener members 30 have the same dimension as a width dimension of the resin material infiltration-blocking member 40 on the hook and loop fastener member 30 (see FIG. 11) and thus the entire width of the hook and loop fastener members 30 in the width direction is fully covered with each of parts thereof between the hook and loop fastener members 30. Thus, as described below, a bonding strength (fixation strength) between the molded hook and loop fastener 2 and a cushion body can be more effectively enhanced.

(116) In addition, each of the rectangular opening portion 43 formed in the resin material infiltration-blocking member 40 has a length dimension smaller than a length dimension of the base material 31 of each hook and loop fastener member 30 and also has a width dimension smaller than a dimension as measured between outer surfaces of the right and left support members 13 of each hook and loop fastener member 30 in the width direction.

(117) As the opening portions 43 of the resin material infiltration-blocking member 40 is set to have such a size, a positional offset of the opening portions 43 of the resin material infiltration-blocking member 40 relative to the engaging element region 18 of each hook and loop fastener member 30 can be hardly occurred. In addition, it is possible to prevent parts of engaging elements 12 or support members 13 from protruding above the resin material infiltration-blocking member 40 from the opening portion 43.

(118) The molded hook and loop fastener 2 of the present embodiment 2 having configurations as described above can be easily bent to be curved or meandered in the right and left direction and the front and back direction as described above (see FIG. 12). When the molded hook and loop fastener 2 is bent in the right and left direction in such a way, the resin material infiltration-blocking member 40 is constructed of a pliable non-woven fabric and thus becomes in a state where in a region of the resin material infiltration-blocking member 40, which bridges between the adjacent hook and loop fastener member 30, a part thereof arranged on the outer circumferential side thereof is pulled and stretched (tensioned) by hook and loop fastener members 30 located front and rear thereof, and a part thereof arranged on the inner circumferential side is bent in a wave shape to create a clearance.

(119) Also, like the foregoing embodiment 1, the molded hook and loop fastener 2 of the present embodiment is integrated with a cushion body (foam body) 6, such as seats of vehicles, while the cushion body is foamed, thereby obtaining the cushion body with the molded hook and loop fastener 2.

(120) According to the cushion body with the molded hook and loop fastener 2 of the present embodiment 2 integrated, like the foregoing embodiment 1, it is possible to prevent the foam body from infiltrating into the engaging element region 38 of the molded hook and loop fastener 2. Therefore, a desired fastening force can be stably ensured by the plurality of engaging elements 12 exposed on the upper surface of the base material 11. Also, costs or workloads required to manufacture the mold 7 for molding the cushion body can be reduced as compared to the related art.

(121) Also, because the molded hook and loop fastener 2 of the present embodiment 2 can be easily bent in the right and left direction as described above, the molded hook and loop fastener 2 can be closely contacted with the cavity surface 7a of the mold 7 in a curved or meandered state. Accordingly, the molded hook and loop fastener 2 of the present embodiment 2 can be easily conformed to various shapes of the cushion body.

(122) In addition, when the molded hook and loop fastener 2 is integrated with the cushion in a curved or meandered state as described above, upon foaming, as described above, a part of the resin material infiltration-blocking member 49, which is arranged on the outer circumferential side thereof, is pulled and thus stretched (tensioned) and also a part thereof, which is arranged on the inner circumferential side, is bent to create a clearance, and in this state, the molded hook and loop fastener 2 is closely contacted with the cavity surface 7a of the mold 7. In this case, a gap is likely to be formed between the bent part of the resin material infiltration-blocking member 40, which is arranged on the inner circumferential side, and the cavity surface 7a of the mold 7, and thus the foaming resin material is likely to be introduced between the resin material infiltration-blocking member 40 and the cavity surface 7a through the gap.

(123) In this state, when the foaming resin material is injected into the mold 7, the foaming resin material can be also allowed to be introduced and foamed on the back side of the resin material infiltration-blocking member 40 between the adjacent hook and loop fastener members 30. Thus, the cushion body having a predetermined shape can be stably manufactured.

(124) Also, in the present embodiment 2, the tensioned part on the outer circumferential side and the bent part on the inner circumferential side of the resin material infiltration-blocking member 40, which are arranged between the hook and loop fastener members 30, as well as the connection member constructed of the monofilament 45 can be embedded in the molded cushion body. Accordingly, a bonding strength (fixation strength) between the molded hook and loop fastener 2 and the cushion body can be effectively increased.

(125) In particular, as described above, the sheet-shaped resin material infiltration-blocking member 40 covers the hook and loop fastener members 30 over the entire width thereof in the width direction. Thus, the resin material infiltration-blocking member 40 is embedded over a broad area in the cushion body due to parts thereof between the adjacent hook and loop fastener members 30, thereby further enhancing the bonding strength (fixation strength) between the molded hook and loop fastener 2 and the cushion body.

Embodiment 3

(126) FIG. 13 is a plan view showing a molded hook and loop fastener according to the present embodiment 3, FIG. 14 is a sectional view taken along a XIV-XIV line shown in FIG. 13.

(127) The molded hook and loop fastener 3 according to the present embodiment 3 includes one hook and loop fastener member 10 having a plurality of engaging elements 12 erected on an upper surface of a base material 11, and right and left independent resin material infiltration-blocking members 50. The hook and loop fastener member 10 of the present embodiment 3 has the same configurations as those of the hook and loop fastener member 10 of the forgoing embodiment 1.

(128) The resin material infiltration-blocking members 50 of the present embodiment 3 are respectively independently fixed to right and left side edge portions 11a of the base material 11 of the hook and loop fastener member 10. The right and left resin infiltration-blocking members 50 are constructed of a sheet member made of a flexible thin piece-shaped non-woven fabric and have a tubular shape in which the thin piece-shaped sheet member is rolled by bonding side edge portions of the sheet member to each other.

(129) In this case, the non-woven fabric constructing the resin material infiltration-blocking members 50 has suitable flexibility, pliability and swollen feeling. Also, the resin material infiltration-blocking members 50 formed in a tubular shape have the same length dimension as a length dimension of the base material 11 of the hook and loop fastener member 10.

(130) Also, as shown in FIG. 14, the tubular-shaped resin material infiltration-blocking members 50 of the present embodiment 3 are fixed to the hook and loop fastener member 10 by bonding or welding bonded portions, at which the side edge portions thereof are bonded to each other, to right and left side edge portions 11a of the base material 11 in a state where the resin material infiltration-blocking members 50 are supported by right and left support members 13 while protruding upper ends thereof above upper end locations of the support members 13. In this case, preferably, the tubular-shaped resin material infiltration-blocking members 50 are also fixed to outer surfaces of the support members 13.

(131) The molded hook and loop fastener 3 of the present embodiment 3 having the right and left tubular shaped resin material infiltration-blocking member 50 as described above are attracted and fixed to a cavity surface 7a of a cushion body molding mold 7 using a magnetic force of magnets 8 and then are integrated with a cushion body by foaming the cushion body, thereby obtaining the cushion body with the molded hook and loop fastener 3.

(132) In this case, because the molded hook and loop fastener 3 of the present embodiment 3 is configured to protrude the upper ends of the resin material infiltration-blocking members 50 above the upper end locations of the support members 13, the right and left tubular-shaped resin material infiltration-blocking members 50, as shown in FIG. 15, are collapsed and closely contacted to the flat cavity surface 7a of the mold 7 when the molded hook and loop fastener 3 is attracted and fixed to the cavity surface 7a of the mold 7. Thus, it is possible to prevent a gap, which could allow a foaming resin material to pass therethrough, from being formed between the hook and loop fastener member 10 and the cavity surface 7a, between which the resin material infiltration-blocking members 50 are sandwiched.

(133) Also, because the resin material infiltration-blocking members 50 are fixed to the base material 11 while being supported by the right and left support members 13, it is possible to prevent a positional offset of the resin material infiltration-blocking members 50 and also to prevent a gap from being formed between the resin material infiltration-blocking members 50 and the cavity surface 7a, even if a flowing pressure or foaming pressure of the foaming resin material is exerted thereon. Thus, in the present embodiment 3, it is possible to stably prevent the foaming resin material from infiltrating into the engaging element region 18 over the resin material infiltration-blocking members 50 from the right and left direction.

(134) Meanwhile, in the molded hook and loop fastener 3 of the present embodiment 3, the resin material infiltration-blocking members 50 are not arranged on front and rear ends of the hook and loop fastener member 10, but engaging elements 12 and transversal wall bodies 16, which are arranged along the width direction at the front-most location of the hook and loop fastener member 10, and engaging elements 12 and transversal wall bodies 16, which are arranged along the width direction at the rear-most location thereof, sever as transversal blocking wall portions for blocking infiltration of the foaming resin material into the engaging element region 18. Accordingly, it is also possible to prevent the foaming resin material from infiltrating in the front and rear direction.

(135) Specifically, when the molded hook and loop fastener 3 of the present embodiment 3 is attracted and fixed to the flat cavity surface 7a of the mold 7, as shown in FIG. 15, upper end surfaces of the engaging elements 12 and upper end surfaces of the transversal wall bodies 16 of the hook and loop fastener member 10 can be closely contacted with the cavity surface 7a of the mold 7. In this way, by closely contacting the engaging elements 12 and the transversal wall bodies 16 of the hook and loop fastener member 10, the transversal blocking wall portions are constructed by the engaging elements 12 and the transversal wall bodies 16, which are aligned to each other in the width direction, so that infiltration of the foaming resin material into the engaging element region 18 can be blocked by the transversal blocking wall portions.

(136) Meanwhile, in the transversal blocking wall portions constructed by the engaging elements 12 and the transversal wall bodies 16, small gaps are formed between the engaging elements 12 and the transversal wall bodies 16. However, because all of the gaps are very small, even if the foaming resin material is introduced through the gaps, the foaming resin material is cooled and solidified before infiltrating into the engaging element region 18 or immediately after infiltrating into the engaging element region 18. Accordingly, the foaming resin material cannot reach deeply into the engaging element region 18 through the gaps of the transversal blocking wall portions 14.

(137) Therefore, in the cushion body, with which the molded hook and loop fastener 3 of the present embodiment 3 is integrated, the foaming resin material does not infiltrate into the engaging element region 18 of the molded hook and loop fastener 3 so that the engaging elements 12 can be stably exposed on the upper surface of the base material 11. Accordingly, a predetermined engaging force (fastening force) inherent in the molded hook and loop fastener 3 can be stably ensured. Also, costs or workloads required to manufacture the mold 7 for molding the cushion body can be reduced as compared to the related art.

Embodiment 4

(138) FIG. 16 is a plan view showing a molded hook and loop fastener according to the present embodiment 4, and FIG. 17 is a sectional view taken along a XVII-XVII line shown in FIG. 16.

(139) The molded hook and loop fastener 4 according to the present embodiment 4 includes one hook and loop fastener member 10 having a plurality of engaging elements 12 erected on an upper surface of a base material 11, and right and left independent resin material infiltration-blocking members 51. The hook and loop fastener member 10 of the present embodiment 4 has the same configurations as those of the hook and loop fastener member 10 of the forgoing embodiment 1.

(140) The resin material infiltration-blocking members 51 of the present embodiment 4 are respectively independently fixed to right and left side edge portions 11a of the base material 11 of the hook and loop fastener member 10. The right and left resin infiltration-blocking members 51 are constructed of a sheet member made of a flexible thin piece-shaped non-woven.

(141) In this case, the non-woven fabric constructing the resin material infiltration-blocking members 51 has suitable flexibility, pliability and swollen feeling. Also, the resin material infiltration-blocking members 51 have the same length dimension as a length dimension of the base material 11 of the hook and loop fastener member 10.

(142) In addition, as shown in FIG. 17, the resin material infiltration-blocking members 51 of the present embodiment 4 are boned or welded to the right and left side edge portions 11a of the base material 11 and outer surfaces of right and left support members 13 in a state where the resin material infiltration-blocking members 51 are supported by the support members 13 while protruding upper ends thereof above upper end locations of the support members 13. By doing so, the resin material infiltration-blocking members 51 are fixed to the hook and loop fastener member 10 to have a generally L-shape.

(143) The molded hook and loop fastener 4 of the present embodiment 4 having the right and left resin material infiltration-blocking member 51 as described above are attracted and fixed to a cavity surface 7a of a cushion body molding mold 7 using a magnetic force of magnets 8 and then are integrated with a cushion body by foaming the cushion body, thereby obtaining the cushion body with the molded hook and loop fastener 4.

(144) In this case, because the molded hook and loop fastener 4 of the present embodiment 4 is configured to protrude the upper ends of the resin material infiltration-blocking members 51 above the upper end locations of the support members 13, the upper ends of the resin material infiltration-blocking members 51 are bent outward and closely contacted to the flat cavity surface 7a of the mold 7 when the molded hook and loop fastener 4 is attracted and fixed to the cavity surface 7a of the mold 7. Thus, it is possible to prevent a gap, which could allow a foaming resin material to pass therethrough, from being formed between the hook and loop fastener member 10 and the cavity surface 7a, between which the resin material infiltration-blocking members 51 are sandwiched.

(145) Also, because the resin material infiltration-blocking members 51 are fixed to the base material 11 while being supported by the support members 13, it is possible to prevent a positional offset of the resin material infiltration-blocking members 51 and also to prevent a gap from being formed between the resin material infiltration-blocking members 51 and the cavity surface 7a, even if a flowing pressure or foaming pressure of the foaming resin material is exerted thereon. Thus, in the present embodiment 4, it is possible to stably prevent the foaming resin material from infiltrating into the engaging element region 18 over the resin material infiltration-blocking members 51 from the right and left direction.

(146) Meanwhile, in the molded hook and loop fastener 4 of the present embodiment 4, the resin material infiltration-blocking members 51 are not arranged on front and rear ends of the hook and loop fastener member 10, but like the foregoing embodiment 3, engaging elements 12 and transversal wall bodies 16, which are arranged along the width direction at the front-most location of the hook and loop fastener member 10, and engaging elements 12 and transversal wall bodies 16, which are arranged along the width direction at the rear-most location thereof, sever as transversal blocking wall portions for blocking infiltration of the foaming resin material into the engaging element region 18. Accordingly, it is also possible to prevent the foaming resin material from infiltrating in the front and rear direction.

(147) Accordingly, in the cushion body, with which the molded hook and loop fastener 4 of the present embodiment 4 is integrated, the foaming resin material does not infiltrate into the engaging element region 18 of the molded hook and loop fastener 4 so that the engaging elements 12 can be stably exposed on the upper surface of the base material 11. Accordingly, a predetermined engaging force (fastening force) inherent in the molded hook and loop fastener 4 can be stably ensured. Also, costs or workloads required to manufacture the mold 7 for molding the cushion body can be reduced as compared to the related art.

Embodiment 5

(148) FIG. 18 is a plan view showing a molded hook and loop fastener according to the present embodiment 5, and FIG. 19 is a plan view showing a hook and loop fastener member of the molded hook and loop fastener. Also, FIGS. 20 and 21 are sectional views taken along a XX-XX line and a XX-XX line shown in FIG. 18.

(149) The molded hook and loop fastener 5 according to the present embodiment 5 includes one hook and loop fastener member 60 having a plurality of engaging elements 12 erected on an upper surface of a base material 61 and a resin material infiltration-blocking member 70 fixed to the hook and loop fastener member 60 and having a frame shape.

(150) The hook and loop fastener member 60 according to the present embodiment 5 includes a flat plate-shaped base material 61 and a plurality of engaging elements (male engaging elements) 12 erected on the upper surface of the base material 61, but the right and left support members 13, transversal wall bodies 16, linear magnetic bodies 14 and fixation portions 15 arranged on the hook and loop fastener member 10 of the foregoing embodiment 1 are excluded from the hook and loop fastener member 60 of the present embodiment 5. Also, in the present embodiment 5, the hook and loop fastener member 60 is configured to have a magnetic property by mixing or kneading magnetic particles to a synthetic resin constructing the hook and loop fastener member 60.

(151) The base material 61 of the hook and loop fastener member 60 has a rectangular thin plate shape elongated in the front and rear direction (longitudinal direction) as viewed in the upward and downward direction.

(152) The engaging elements 12 according to the present embodiment 5 are erected on the upper surface of the base material 61 to be aligned at a predetermined attachment pitch in the longitudinal direction and the width direction and thus form an engaging element region 68 of the hook and loop fastener member 60 of the present embodiment 5. In particular, in the case of the present embodiment 5, longitudinal rows of engaging elements 12 aligned along the longitudinal direction are arranged to be arrayed in seven rows in the width direction. Also, each engaging element 12 of the present embodiment 5 has an erection portion perpendicularly erected from the upper surface of the base material 61 and a hook-shaped engaging head portion branched and curved in the front and rear direction at an upper end of the erection portion, and thus the shape itself of the engaging elements 12 are the same as that of the engaging elements 12 of the foregoing embodiment 1.

(153) The hook and loop fastener member 60 according to the present embodiment 5 is not provided with the right and left support members 13 arranged on the hook and loop fastener member 10 of the foregoing embodiment 1, but engaging elements 12, which are arranged in the outermost longitudinal rows in the width direction, (i.e., engaging elements 12 arranged in the leftmost longitudinal row and engaging elements 12 arranged in the rightmost longitudinal row) are configured as engaging elements 12 for forming the engaging element region 68 and also are configured to serve as support members for supporting longitudinal frame portions 71, as described below, of the resin material infiltration-blocking member 70.

(154) Also, engaging elements 12, which are arranged in the front-most transversal row in the longitudinal direction, and engaging elements 12, which are arranged in the rear-most transversal row, are configured as engaging elements 12 for forming the engaging element region 68 and also are configured to serve as support members 13 for supporting transversal frame portions 72, as described below, of the resin material infiltration-blocking member 70.

(155) The resin material infiltration-blocking member 70 according to the present embodiment 5 is constructed of a sheet member made of a flexible thin piece-shaped non-woven fabric. The resin material infiltration-blocking member 70 has a frame shape. Namely, the resin material infiltration-blocking member 70 has right and left longitudinal frame portions (first frame portions) 71 arranged along the longitudinal direction of the molded hook and loop fastener 5 and transversal frame portions (second frame portions) 72 arranged along the width direction to correspond to locations of front and rear end portions of the hook and loop fastener member 60 and configured to connect the right and left longitudinal frame portions 71 with each other. Also, a rectangular opening portion 73 is formed in a center portion of the resin material infiltration-blocking member 70 to be surrounded by the right and left longitudinal frame portions 71 and the front and rear transversal frame portions 72.

(156) The right and left longitudinal frame portions 71 of the resin material infiltration-blocking member 70 are bonded or welded to the right and left side edge portions 61a of the base material 61 of the hook and loop fastener member 60 while protruding inner peripheral edge portions (inner peripheral edge portions at the side of the opening portion 73) of the longitudinal frame portions 71 above upper end locations of the engaging elements 12. Also, the front and rear transversal frame portions 72 are bonded or welded to front and rear end edge portions 61c of the base material 61 of the hook and loop fastener member 60 while protruding inner peripheral edge portions (side edge portion 61a of the opening portion 73) of the transversal frame portions 72 above upper end locations of the engaging elements 12.

(157) At this time, the right and left longitudinal frame portions 71 and front and rear transversal frame portions 72 of the resin material infiltration-blocking member 70 are respectively supported by a plurality of engaging elements (support member) 12 of the hook and loop fastener member 60, which are arranged in the rightmost and leftmost longitudinal rows in the width direction, and a plurality of engaging elements (support member) 12, which are arranged in the front-most and rear-most transversal rows in the longitudinal direction.

(158) Thus, the longitudinal frame portions 71 and transversal frame portions 72 of the resin material infiltration-blocking member 70 are hardly collapsed or bend even if a flowing pressure or foaming pressure of a foaming resin material is exerted thereon when a cushion body is foamed, and also the state where the inner peripheral edge portions of the longitudinal frame portions 71 and transversal frame portions 72 are protruded above the upper end locations of the engaging elements 12 can be stably kept.

(159) In the present embodiment 5, a length dimension of the resin material infiltration-blocking member 70 (i.e., a length dimension of the longitudinal frame portions 71) is set to be larger than a length dimension of the base material 61 of the hook and loop fastener member 60 when the resin material infiltration-blocking member 70 is in a flat state before being attached to the hook and loop fastener member 60, and also even when the resin material infiltration-blocking member 70 is in a state after being fixed to the hook and loop fastener member 10 and thus being partially bent, the resin material infiltration-blocking member 20 is set to have a length dimension larger than that of the base material 61 of the hook and loop fastener member 60.

(160) A width dimension of the resin material infiltration-blocking member 70 (i.e., a dimension between outer side edges of the right and left longitudinal frame portions 71 in the width direction) is set to be larger than a width dimension of the base material 61 of the hook and loop fastener member 60 when the resin material infiltration-blocking member 70 is in a flat state before being attached to the hook and loop fastener member 60, and also even when the resin material infiltration-blocking member 70 is in a state after being fixed to the hook and loop fastener member 60 and thus being partially bent, the resin material infiltration-blocking member 70 is set to have a width dimension larger than that of the base material 61 of the hook and loop fastener member 60.

(161) Namely, when being fixed to the hook and loop fastener member 60, the resin material infiltration-blocking member 70 of the present embodiment 5 has right and left first extension portions 74 extending outward beyond right and left end edges of the base material 61 of the hook and loop fastener member 60 and front and rear second extension portions 75 extending outward beyond front and rear end edges of the base material 61 of the hook and loop fastener member 60.

(162) In addition, the rectangular opening portion 73 formed in the center portion of the resin material infiltration-blocking member 70 has length and width dimensions smaller than length and width dimensions of the base material 61 of the hook and loop fastener member 60. Accordingly, a positional offset of the opening portion 73 of the resin material infiltration-blocking member 70 relative to the engaging element region 68 of the hook and loop fastener member 60 can be hardly occurred.

(163) The molded hook and loop fastener 5 of the present embodiment 5 having configurations as described above are attracted and fixed to a cavity surface 7a of a cushion body molding mold 7 using a magnetic force of magnets 8 and then are integrated with a cushion body by foaming the cushion body, thereby obtaining the cushion body with the molded hook and loop fastener 5.

(164) In this case, because the molded hook and loop fastener 5 of the present embodiment 5 is configured so that the inner peripheral edge portions of the right and left longitudinal frame portions 71 and front and rear transversal frame portions 72 of the resin material infiltration-blocking member 70 are protruded above the upper end locations of the engaging elements 12, the inner peripheral edge portions of the resin material infiltration-blocking member 70 can be closely contacted with the flat cavity surface 7a of the mold 7 when the molded hook and loop fastener 5 is attracted and fixed to the cavity surface 7a of the mold 7. Thus, it is possible to prevent a gap, which could allow the foaming resin material to pass therethrough, from being formed between the hook and loop fastener member 60 and the cavity surface 7a, between which the resin material infiltration-blocking member 70 is sandwiched.

(165) Also, because the resin material infiltration-blocking member 70 is fixed to the right and left side edge portions 61a and front and rear end edge portions 61c of the baste material 61 while being supported by the engaging elements 12 as described above, it is possible to prevent a positional offset of the resin material infiltration-blocking member 70 and also to prevent a gap from being formed between the resin material infiltration-blocking member 70 and the cavity surface 7a, even if a flowing pressure or foaming pressure of the foaming resin material is exerted thereon. Thus, in the present embodiment 4, it is possible to stably prevent the foaming resin material from infiltrating into the engaging element region 68 over the resin material infiltration-blocking member 70 from the right and left direction and the front and rear direction.

(166) Therefore, in the cushion body, with which the molded hook and loop fastener 5 of the present embodiment 5 is integrated, the foaming resin material does not infiltrate into the engaging element region 68 of the molded hook and loop fastener 5 so that the engaging elements 12 can be stably exposed on the upper surface of the base material 61. Accordingly, a predetermined engaging force (fastening force) inherent in the molded hook and loop fastener 5 can be stably ensured. Also, costs or workloads required to manufacture the mold 7 for molding the cushion body can be reduced as compared to the related art.

(167) Further, in the cushion body with which the molded hook and loop fastener 5 of the present embodiment 5 is integrated, the first and second extension portions 74 and 75 of the resin material infiltration-blocking member 70 extending from the base material 61 are embedded in the cushion body. Accordingly, a bonding strength (fixation strength) between the molded hook and loop fastener 5 and the cushion body can be effectively increased, so that the molded hook and loop fastener 5 can be more strongly integrated with the cushion body.
