DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0090] Next, a clip 10 of the first embodiment of the present invention will be explained by referring to the Drawings. FIG. 4 is a top plan view of clip 10 according to the first embodiment. FIG. 5 is a front elevational view of clip 10; FIG. 6 is a bottom plan view; FIG. 7 is a left side elevational view; and FIG. 8 is a right side elevational view.

[0091] In the present Specification, the depth direction (the axial direction of the pipe) in FIGS. 5 and 11 will be called the depth direction. The upward direction in FIG. 5 will be called the upward direction; and the downward direction will be called the downward direction. The horizontal direction will be called the width direction.

[0092] Clip 10 is an auxiliary clamp device used with clamp 20 (see FIGS. 10-15), and is housed in the housing of the clamp, and holds a tubular part such as a pipe or the like. Clip 10 has a pipe clamp portion 11 which holds a tubular part such as a pipe or the like, by abutting the outer circumferential surface of the pipe. Pipe clamp portion 11 is cylindrical, and part of it, in the upward direction in FIG. 5, is open along the axial direction so that the pipe or component can be pushed from this opening into a component holding space inside pipe clamp portion 11. When clip 10 is in its ordinary state, the inner diameter of pipe clamp portion 11 is φd1. The outer diameter of pipe clamp portion 11 is φD1. The length of pipe clamp portion 11 in the axial direction is slightly longer than the length of the clamp 20 in the axial direction (see, for example, FIG. 10).

[0093] As shown in FIG. 5, a pair of insert guide plates 12 extends from the top of pipe clamp portion 11 adjacent respective circumferentially-opposed end portions 15 so as to widen obliquely upwardly or outwardly. The length of insert guide plates 12 in the axial direction is the same as the length of pipe clamp portion 11 in the axial direction. The configuration of insert guide plates 12 is substantially rectangular.

[0094] When the component is inserted in pipe clamp portion 11, if the component abuts insert guide plates 12 as it is pushed in, insert guide plates 12 separate from one another, enabling insertion of the component into pipe clamp portion 11.

[0095] In the first embodiment of the present invention, clip 10 has a pair of insert guide plates 12. Clip 10 is used in combination with clamp 20, which has a pair of prongs 24 (see, for example, FIG. 11).

[0096] In other embodiments, there may also be only one insert guide plate 12. In a clip 10 with one insert guide plate 12, the component is pushed in while it abuts between one insert guide plate 12 and the side surfaces of the clip on the other side. A clamp with one prong 24 is used mainly in combination with a clip having one insert guide plate 12.

[0097] Referring to FIGS. 5, 7 and 8, raised stoppers 13 extend in the axial direction, near the respective starting points of insert guide plates 12, which are on the top of pipe clamp portion 11 in FIG. 5. Prongs 24 of clamp 20 engage with stoppers 13, as will be described later.

[0098] In the first embodiment of the present invention, clip 10 has a pair of stoppers 13. Clip 10 is used in combination with clamp 20, which has a pair of prongs 24.

[0099] In other embodiments, there may be only one stopper 13. A clip with one stopper 13 is used mainly in combination with a clamp having one prong 24.

[0100] As shown in FIGS. 5, 7 and 8, one raised slip-preventing plate 14 is formed on one end of pipe clamp portion in the axial direction, so as to extend widthwise. Also as shown in FIGS. 5, 7 and 8, another raised slip-preventing plate 14 is formed on the other end of pipe clamp portion 11 in the axial direction, so as to extend in the other width direction. Slip-preventing plates 14 engage the ends of clamp 20 in the axial direction, and clip 10 is thus held so that it does not slip in the axial direction relative to clamp 20 (see FIGS. 10-15).

[0101] In the first embodiment of the present invention, clip 10 has a pair of slip-preventing plates 14.

[0102] In other embodiments, there may be only one slip-preventing plate 14, which is placed on one end of clip 10 in the axial direction only. Also, in still other embodiments, there may be four slip-preventing plates 14, with one pair placed on one end in the axial direction so as to extend widthwise towards both sides, and another pair of slip-preventing plates 14 placed on the other end in the axial direction so as to extend widthwise towards both sides. Furthermore, there may be three slip-preventing plates 14, with one pair of slip-preventing plates 14 placed on one end in the axial direction, and one slip-preventing plate 14 placed on the other end in the axial direction.

[0103] Next, clip 10 mounted on pipe P2 will be explained. FIG. 9 is a front elevational view which shows clip 10 mounted on pipe P2. The outer diameter of pipe P2 is φd2. More precisely, when dimensional tolerances are taken into account, the minimum outer diameter is φd2. The inner diameter φd1 of pipe clamp portion 11 when clip 10 is in its natural state (see FIG. 5) is smaller than the minimum diameter φd2 of pipe P2. That is, φd1<φd2.

[0104] When in the state shown in FIG. 9, the inner diameter of pipe clamp portion 11 widens more than φd1 and becomes approximately equal to outer diameter φd2 of pipe P2, because clip 10 holds pipe P2 which has the outer diameter φd2. When pipe P2 is held, the outer diameter of pipe clamp portion 11 becomes slightly larger than φD1, however. In FIG. 9, this is shown by φD1.

[0105] Still referring to FIG. 9, on clip 10, insert guide plates 12 exert a force that narrows the open portion or gap in the direction of arrows J in the diagram, and pipe clamp portion 11 is mated tightly with pipe P2, enabling pipe P2 to be held securely. The gap is the open portion bounded by insert guide plates 12 and pipe clamp portion 11.

[0106] When pipe P2 is in the held position, the gap is at a minimum width H.

[0107] Clip 10 abuts the outer circumferential surface of pipe P2 over a wide area of pipe clamp portion 11, with the exception of the open portion. The area of contact with pipe P2 is greatly increased, and the friction force is greatly improved, compared with pipe P2 being held by only the clamp 20.

[0108] If clip 10 is to be mounted to a soft plastic tube (or a rubber hose), the minimum width H is made smaller than the horizontal width of the plastic tube undergoing deformation. If clip 10 is mounted to a soft plastic tube, the same efficacy is obtained as if the clamped portion of the plastic tube had been rigid; even when mounted to clamp 20, there are no defects such as occur when the tube falls out or is damaged.

[0109] As a result, there is no need to use a clamp with a cover.

[0110] FIG. 10 is a top plan view of clip 10 and clamp 20 mounted to pipe P2. FIG. 11 is a front elevational view; FIG. 12 is a bottom plan view; FIG. 13 is a left side elevational view; and FIG. 14 is a right side elevational view.

[0111] As shown in FIG. 9, clip 10 is mounted to pipe P2; and next, as shown in FIG. 11, clamp 20 is attached to clip 10 that has been mounted to pipe P2.

[0112] Clip 10 mounted on clamp 20 is called “the clamp assembly.”

[0113] Next, clamp 20 will be explained. Clamp 20 is provided with a clamp portion which holds pipe P2 and a locking portion which secures to a workpiece, such as a body panel or the like. The clamp portion has a main body 22. The main body 22 defines a housing or channel 23, having a “U”-shaped cross-section. The bottom of the “U” has a semicircular cross-section. The inner diameter of housing or channel 23 is approximately equal to the outer diameter of pipe clamp portion 11 (which is approximately φD1) when pipe P2 is mounted in clip 10. Clip 10 and pipe P2 are mounted in housing 23. The main body 22 defines two top ends 21, each of which is formed on each side of the main body.

[0114] The main body 22 of clamp 20 has a pair of prongs 24, each of which extend obliquely downwardly (or radially inwardly) from each top end 21 of the main body, which prongs are formed on each side of main body 22. Prongs 24 abut the stoppers 13 which are formed on the outer circumference of pipe clamp portion 11 of clip 10, without directly abutting pipe P2 (FIGS. 11 and 15).

[0115] Protuberances 25 are formed on the bottom surface of main body 22, which abut the panel (the workpiece) when the panel is attached. The locking portion on the bottom of clamp 20 has a columnar portion 26 which extends downwardly from the center of main body 22, and a pair of locking legs 27 which extend from the tip of columnar portion 26 obliquely upwardly, for mounting in an attaching hole of the workpiece.

[0116] In the first embodiment of the present invention, clamp 20 has a pair of prongs 24.

[0117] In other embodiments, there may be only one prong 24. In a clamp 20 with one prong 24, the clip with the mounted component is pushed in and made to abut between one prong 24 and the side surface of clamp 20 on the other side. A clamp 20 with only one prong 24 is used mainly in combination with a clip 10 which has only one insert guide plate 12.

[0118] In the first embodiment of the present invention, the locking portion is comprised of a columnar portion 25 and locking legs 27, but the locking portion is not limited to this structure. In other embodiments, the locking portion may be anything that attaches clamp 20 to a workpiece, such as a panel or the like. Also, the locking portion may be a structure that attaches to a stud erected perpendicularly on the panel.

[0119] Next, referring to FIGS. 10-14, the process for mounting clip 10 with the attached pipe P2 to clamp 20 will be explained. The axial directions of clip 10 and clamp 20 are aligned, and main body 22 of clamp 20 is positioned so that it enters between slip-preventing plates 14 of clip 10. Pipe clamp portion 11 of clip 10 is made to abut on prongs 24 of clamp 20, and pipe clamp portion 11 is pushed in and housed in housing 23.

[0120] The tips of prongs 24 abut stoppers 13 and are thus held without widening. As a result, it is difficult to remove pipe P2 after clip 10 is mounted in clamp 20.

[0121] If there is only one prong 24, the pipe clamp portion is pushed in between one prong 24 and the surface of the housing on the other side.

[0122] As shown in FIG. 11, the outside lower surfaces of insert guide plates 12 abut the inside top surfaces of prongs 24. The slope of insert guide plates 12 and the slope of prongs 24 are approximately equal. The gap between the opposing surfaces of prongs 24 is made narrower than the gap between the outer surfaces of the pair of insert guide plates 12. As a result, a force is applied on insert guide plates 12 by means of prongs 24, which narrows the gap of the open portion of the clip 10 in the direction of arrows K. As shown in FIG. 9, clip 10 alone produces a force in the direction of arrows J, and when this force is combined with force K from prongs 24, pipe P2 can be held securely.

[0123] Insert guide plates 12 abut prongs 24, and as a result, clip 10 is held without rotating relative to clamp 20.

[0124] As shown in FIGS. 13 and 14, one slip-preventing plate 14 of clip 10 abuts on one surface of main body 22 of clamp 20 in the axial direction, and another slip-preventing plate 14 of clip 10 abuts on the other surface of main body 22 in the axial direction; clip 10 is thus held so that it does not slip horizontally relative to clamp 20.

[0125] If only one slip-preventing plate 14 is used, clip 10 can be held so that it does not slip horizontally in one direction. If two pairs of slip-preventing plates 14 are used, it can be held even more securely.

[0126] The length of prongs 24 is designed so that tips of prongs 24 abut stoppers 13 when pipe clamp portion 11 of clip 10 is placed in housing 23 of clamp 20.

[0127] As shown in FIG. 11, if a force L is applied to pipe P2 tending to pull out pipe P2, prongs 24 apply a counteracting force which moves along the outer circumference of clip 10 in the direction M. However, stoppers 13 abut at the tips of prongs 24, and prongs 24 cannot move in the direction M. As a result, clip 10 cannot be removed from housing 23 of clamp 20, and it is thus possible to prevent pipe P2 from being removed from pipe clamp portion 11 of clip 10.

[0128] Next, the method for mounting pipe P2 to a workpiece such as a panel or the like will be explained. Locking legs 27 of clamp 20 are inserted into the attaching hole of the panel. When the locking legs 27 are compressed by the inner circumferential surface of the attaching hole, the space between locking legs 27 becomes smaller, and locking legs 27 pass through the attaching hole. Protuberances 25 abut the surface of the panel; and clamp 20 is attached to the panel when the tips 27a of locking legs 27 engage in the inner circumference of the attaching hole.

[0129] Next, the mounting of pipes with different outer diameters will be explained. The outer diameter of pipe clamp portion 11 of clip 10 is equal to approximately φD1, and by changing the inner diameter of pipe clamp portion 11 to match the pipe, pipes having an outer diameter that is different from outer diameter φd2 can be attached.

[0130] If the outer diameter of the pipe to be attached does not vary too greatly from the outer diameter φd2 of pipe P2, this can be done by changing the inner diameter of pipe clamp portion 11, that is, by changing its thickness.

[0131] If the pipe to be attached has a small outer diameter, and there is a great difference between outer diameter φD1 of clip 10 and the outer diameter of the pipe, the sheet thickness of pipe clamp portion 11 of clip 10 becomes thick and difficult to bend. To accommodate this case, the outer diameter of the clip 10 of the present invention is made smaller than φD1, and the outer diameter of the plurality of ribs 16 which are formed on the outer circumference of pipe clamp portion 11 is made to be φD1. The thickness of pipe clamp portion 11 is therefore reduced, and as a result, it becomes easily bendable and can be placed in the same clamp 20 as were the clamps described earlier.

[0132] FIG. 15 is a front elevational view of a pipe P3 that has an outer diameter φd3, which is less than the outer diameter φd2 of pipe P2, and which is mounted using clip 10b of the second embodiment of the present invention.

[0133] Clamp 20 is the same clamp 20 explained above with reference to FIG. 11. The inner diameter of housing 23 is approximately equal to the outer diameter of pipe clamp portion 11 of clip 10 (which is approximately φD1). The inner diameter of clip 10b conforms to the outer diameter φd3 of pipe P3. The outer diameter of clip 10b is smaller than φD1.

[0134] Ribs 16 that extend in the axial direction are formed at three locations on the outer circumference of the pipe clamp portion 11. Each rib includes a tip which engages the channel or housing 23 of the clamp 20. The outer diameter of the rib 16 is φD1.

[0135] Thus clip goes 10b can be mounted in housing 23 of clamp 20, in the same manner as clip 10 in FIG. 11.

[0136] A pipe can also be mounted using clamp 20 only, without using clip 10.

[0137] FIG. 16 is a front elevational view of a pipe P4 having an outer diameter φD1, which is attached using clamp 20 only, without using clip 10. If the outer diameter of pipe P4 is greater than φd2, and is approximately equal to outer diameter φD1 of clip 10, pipe P4 can be mounted using clamp 20 only, without using clip 10.

[0138] If pipe P4 is mounted using clamp 20 only, the efficacy of preventing a horizontal slip, which is present when clip 10 is used, is lacking.

[0139] Clamp 20 may be mounted on pipe P4 and then attached to the panel. Or, clamp 20 may be attached to the panel first, and then pipe P4, having an outer diameter φD1, may be attached to clamp 20.

[0140] In the embodiments of the present invention, the inner diameter of pipe clamp portion 11 of clip 10 is smaller than the outer diameter of pipe P2 which is to be mounted; as a result, pipe P2 can be tightly held around its entire circumference, with the exception of the opening for inserting pipe P2.

[0141] Further, clip 10 has insert guide plates 12; as a result, pipe P2 can easily be inserted into pipe clamp portion 11. When clip 10 is mounted in clamp 20, insert guide plates 12 compress, by means of prongs 24, in a direction that narrows the open portion; as a result, the force holding the pipe tightly is increased. Also, clip 10 is held so that it does not rotate relative to clamp 20.

[0142] Prongs 24 of clamp 20 abut stoppers 13 of clip 10, and as a result, even if a force is applied to pipe P2 in the direction of removing the pipe from clamp 20, prongs 24 continue to abut stoppers 13 and cannot move along the outer circumference of pipe clamp portion 11. Therefore, pipe P2 is held and does not fall out.

[0143] Main body 22 of clamp 20 is held from both sides by means of slip-preventing plates 14 of clip 10, and as a result, clip 10 does not slip horizontally from the clamp in the axial direction.

[0144] When pipes having different diameters are mounted, the same clamp 20 is used, and by standardizing the outer diameter of clip 10, which is to be attached to clamp 20, and changing the inner diameter, pipes with different diameters can be mounted.

[0145] In addition, a large diameter pipe P4 can be mounted using clamp 20 only, without using clip 10, if its outer diameter is approximately equal to the inner diameter of housing 23 of clamp 20.

[0146] In one embodiment of the present invention, the clip 10 and clamp 20 are each formed as a resilient unitary body.

[0147] It will be appreciated by persons skilled in the art that the above embodiments have been described by way of example only, and not in any limitative sense, and that various alterations and modifications are possible without departure from the scope of the invention as defined by the appended claims.
