(19)
(20)
(21) The main advantages of the one piece monocoque skate boot body 2 as compared to prior art may include increased strength and stiffness, reduced weight, more response during skating, better and more direct power transfer during the skating push phase, increased manufacturing efficiency, and/or reduced reject rate.
(22) As described above, the skate boot according to the present invention generally includes the skate boot body 2 as a single unitary structure to which is attached a toe cap 101, a lower mounting frame 7 (described above as a blade holder), and a tendon guard 12.
(23) The boot body 2 generally includes a sole portion which extends longitudinally between a toe end and an opposing heel end to form the portion of the boot body upon which the bottom of the foot of the user is supported along the length thereof.
(24) The boot body further includes an inner side wall portion 201 and an outer side wall portion 203 described above as an eyelet cuff 13 in which the side wall portions are generally oriented in the longitudinal direction to extend upwardly from laterally opposing sides of the sole portion at an intermediate location between the toe end and the heel end. The forward ends of the inner and outer side wall portions terminate at respective upright forward edges 210 which extend upwardly from the sole portion at a location spaced rearwardly from the toe end of the sole portion to accommodate the lower toe portion 4 forwardly therefrom. The inner and outer side wall portions extend upwardly to respective upper free edges 43 which are generally longitudinally oriented and which are laterally spaced apart from one another to define a tongue opening therebetween.
(25) The boot body further includes two ankle portions 9 which also extend upwardly from laterally opposing sides of the sole portion in proximity to the heel end thereof so as to be continuous and in connection with respective ones of the side wall portions 13 forwardly thereof. The two ankle portions extend upwardly to respective top edges 29 which are spaced above the height of the side wall portions terminating at the top edges 43 such that the two ankle portions are suited for spanning over respective ankles of the foot of the user.
(26) The heel portion 3 extends upwardly from the heel end of the sole portion in a generally U-shaped arrangement in connection between the two ankle portions 9. The heel portion has a generally concave interior shape for conforming to the heel of the foot of the user received therein.
(27) A lower Achilles tendon portion 10 extends upwardly from the heel portion so as to be similarly connected between the two ankle portions 9. The lower Achilles tendon portion 10 extends upwardly at a slight forward slope relative to the heel portion therebelow while also becoming narrower in width to follow the shape of the base of the tendon area of the foot of the user.
(28) The upper Achilles tendon portion 11 extends upwardly from the lower Achilles tendon portion 10 also connected between the two ankle portions. The upper Achilles tendon portion generally comprises an upright supporting flange 209 having a base which is approximate the upper edge of the liner 16 at the heel end of the boot body, to extend upwardly therefrom at a slight longitudinally forward slope towards an upper edge 200 which is recessed in height relative to the top edges 29 of the ankle portions 9 respectively. The upright supporting flange 209 is received within a slot defined between the inner prong (or inner mounting flange) 102 and the outer prong (or outer mounting flange) 103 in the mounted position of the tendon guard 12 upon the upper Achilles tendon portion 11.
(29) The boot body 2 also includes the lower toe portion 4 in the form of an upright flange terminating at a top edge which is spaced slightly above the sole portion in a generally U-shaped arrangement about the toe end of the sole portion. The top end of the upright flange forming the lower toe portion 4 extends up to only half a height of the toe box defined by the toe cap receiving the toes of the user therein so as to be spaced below an upper wall portion of the toe cap which defines the upper boundary of the toe box receiving the toes of the user therein such that the toe box is covered from above by the toe cap but remains uncovered from above by the monocoque skate boot body as shown in
(30) The toe cap 101 comprises a second unitary body of material different from the material of the boot body, and is joined to the toe end of the sole portion of the boot body. The toe cap 101 generally includes an upright end wall 202 which overlaps an outer side of the lower toe portion at the outermost toe end of the boot body to extend upwardly from the sole portion to a height which is greater than the height of the lower toe portion 4. The toe cap further includes two side walls 204 extending upwardly from laterally opposing sides of the sole portion at the toe end thereof in a generally U-shaped configuration with the end wall, similarly overlapping respective portions of the lower toe portion 4 of the boot body. An upper portion 206 of the toe cap, which forms the upper boundary, spans laterally between the two opposed side walls and is joined to the top end of the end wall to fully enclose the top end of the toe box area defined by the toe cap. The upper portion of the toe cap is spaced above the toe end of the sole portion to define the internal height of the toe box area therebetween.
(31) The toe cap 101 further includes a lower flange portion 208 extending generally horizontally or laterally inwardly from the bottom end of each of the two side walls and the end wall of the toe cap in an overlapping configuration below the bottom side of the sole portion at the toe end thereof in a generally U-shaped configuration. The blade holder, or lower mounting frame 7, which mounts an ice skate blade or in-line skate rollers thereon for example, is fastened to the boot body at the forward end thereof by forward fasteners 207 which are fastened through the lower flange portion of the toe cap at the toe end of the boot body.
(32) The two side walls of the toe cap extend rearwardly beyond the upright forward edges of the two side walls of the boot body such that a portion of the side walls of the toe cap overlaps longitudinally along the outer side of the forward portions of the two side walls portions 13 of the boot body. The side walls of the toe cap thus overlap two forwardmost ones of the eyelet holes 14 in each of the side wall portions 13 of the boot body so that corresponding eyelet openings 205 in the side walls of the toe cap align with the respective ones of the eyelet openings in the side wall portions. This permits the eyelet fasteners 15 received therethrough to form a mechanically fastened connection at each of the overlapping eyelet opening locations.
(33) The rear edge of each of the two side walls of the toe cap is spaced rearwardly from the upright forward edges 210 of the side wall portions 13 of the boot body and are generally upright in orientation. Each rear edge 212 of the side walls of the toe cap is further provided with a stepped flange 107 where the side wall thickness is reduced relative to a remainder of the side wall of the toe cap so as to be stepped inwardly towards the interior of the skate body boot relative to the remainder of the toe cap. The two outer layers 19 are provided as outer panels bonded to the outer sides of the side wall portions 13 and ankle portions 9 of the boot body such that the forward portions 214 thereof overlap over the exterior of the stepped flange 107 of the toe cap. Suitable stitching is provided to further join the forward edges of the outer panels 19 to the respective flanges 107 at each side of the boot body.
(34) The upper portion of the toe cap includes a slotted opening along the rear edge thereof at a laterally central location between the two side walls for alignment with the tongue opening between the top edges 43 of the side wall portions 13 of the boot body. The fastener hole 25 for securing of the tongue 20 to the toe cap is provided in the upper portion of the toe cap body at a location forwardly of the slotted opening in the rear edge thereof.
(35) The tendon guard 12 also comprises a single unitary body formed separately from the boot body and the toe cap for subsequent connection thereto as described herein. The tendon guard 12 generally includes a lower mounting portion defined by the inner prong 102 (also referred to herein as the inner mounting flange) and the outer prong 103 (also referred to herein as the outer mounting flange). The tendon guard further includes an upper guard portion defined as the remainder of the body of the tendon guard extending upwardly above the lower mounting portion defined by the inner and outer prongs.
(36) The inner mounting flange 102 and the outer mounting flange 103 are generally planar flanges which are substantially parallel and spaced apart from one another by the thickness of the upright supporting flange of the upper Achilles tendon portion 11 to permit the upright supporting flange of the boot body to be received therein in a mounted configuration. The inner and outer mounting flanges are narrower in width than the upper guard portion as the upper guard portion of the tendon guard diverges laterally outwardly in width at both side edges relative to corresponding side edges of the inner and outer mounting flanges of the lower mounting portion therebelow. The lower mounting portion is thus suited to be received overtop, of the upright supporting flange of the upper Achilles tendon portion 11 of the skate boot body. The upright supporting flange is recessed rearwardly relative to a remaining portion of the boot body surrounding the upright supporting flange by at least a thickness of the inner mounting flange. In this manner, an inner surface of the inner mounting flange in the mounted position is substantially flush with or is recessed rearwardly in relation to adjacent portions of the upper Achilles portion and ankle portions 9 of the surrounding boot body.
(37) The bottom edge of the inner mounting flange of the tendon guard abuts the top edge of the liner material 16 at the heel portion and lower Achilles tendon portion 10 of the boot body. The thickness of the inner mounting flange at the bottom edge thereof is thinner than the thickness of the upper edge of the liner 16 such that the inner surface of the tendon guard is recessed rearwardly relative to the inner surface of the finer 16 along an inner surface at the rear of the skate boot.
(38) A single fastener 27 is used for extending commonly through each of the inner mounting flange, the upright supporting flange, and the outer mounting flange.
(39) According to the embodiment of
(40) Since various modifications can be made in my invention as herein above described, it is intended that all matter contained in the accompanying specification shall be interpreted as illustrative only and not in a limiting sense.
