DETAILED DESCRIPTION OF PARTICULAR EMBODIMENTS

(5) Referring now to FIG. 1, a skate according to a particular embodiment of the present invention is generally shown at 10. The skate 10 includes a boot 12, to which is attached a blade assembly 14. Although the skate 10 is depicted as an ice skate, it is to be understood that the present invention as described herein can equally apply to other types of skates, such as for example an in-line roller skate.

(6) The boot 12 of the skate 10 generally includes an outsole 16 to which is connected the blade assembly 14, a toe cap 18 extending from the outsole 16 to surround and protect the toes, a tongue 20 extending from the toe cap 18 to cover the instep of the foot, and an upper 22 connected to the toe cap 18 and the outsole 16 to surround and protect the remainder of the foot and ankle.

(7) The upper 22 of the boot 12 includes a vamp 24 connected to the toe cap 18, two quarters 26 (only one of which is shown in FIG. 1) each covering a respective side of the foot and ankle, an instep portion 28 at least partly covering the tongue 20, and a rear portion 30 extending from the outsole 16 to cover the rear of the foot and ankle.

(8) Each quarter 26 extends upwardly from the outsole 16 and has an approximate L shape, defined by a bottom section 32 covering a side of the foot and a top section 34 extending from the bottom section 32 at the rear thereof to cover a side of the ankle. The bottom section 32 includes a forward finger portion 36 that extends forwardly therefrom, spaced apart from the outsole 16.

(9) The vamp 24 includes inner and outer sections 38 (only one of which is shown) for respectively covering a front part of an inner and outer side of the foot. Each vamp section 38 extends upwardly from the outsole 16 and extends in a fore-aft direction between the bottom section 32 of the respective quarter 26 and the toe cap 18. As such, each vamp section 38 includes a rear finger portion 40 that extends rearwardly therefrom along the outsole 16, and which is complementary to the finger portion 36 of the respective quarter 26 which is disposed thereabove.

(10) The instep portion 28 includes two sections 42 (only one of which is shown) extending upwardly from the respective quarter 26 and vamp section 38. Each section 42 of the instep portion 28 defines along the top thereof a tongue edge 44 extending over the tongue 20. Each section 42 of the instep portion 28 also includes a series of eyelets 46 defined therethrough and which are adjacent the tongue edge 44 and disposed along a substantial part of the length thereof. The two sections 42 of the instep portion 28 are interconnected by a lace 48 extending through the eyelets 46, which when tightened draws the two sections 42 of the opposed instep portions 28 together, such as to fasten the skate boot 12 in place on the foot of the wearer.

(11) The rear portion 30 of the boot 12 extends upwardly from the outsole 16 at the rear thereof. The rear portion 30 includes a tendon guard 50 covering the rear of the foot and ankle and interconnecting the two quarters 26 around the rear of the boot. The rear portion 30 also includes two lateral sections 52 (only one of which is shown) extending frontwardly from the tendon guard 50 on a respective side of the foot up to the respective section 42 of the instep portion 28, and from the respective quarter 26 to the top line 54 around the opening 56 of the skate boot 12.

(12) The skate boot 12 also includes an optional heel support 58 which extends from, and in at least one embodiment is integrally formed with, the outsole 16 at the rear thereof to cover a bottom portion of the tendon guard 50 for improved support to the heel.

(13) Referring now to the quarters 26 of the boot 12 in more detail, the quarters 26 are preferably made of a material that is more rigid than at least that of the tendon guard 50 and the instep portion 28, and preferably also more rigid that that of the entire remainder of the upper 22 (i.e. the vamp 24, instep portion 28 and rear portion 30). The quarters 26 of the boot are thus made of a different material than a majority of the remainder of the boot. The relatively more rigid quarters 26 on either side of the skate boot therefore provide protection to the sides of the wearer's foot, as well as provide structure to the boot, the remainder of which is made of a softer and/or more flexible material which allows for improved movement of the ankle and foot. As such, both good support and protection is provided to the side of the ankle and foot, while allowing for a comfortable and flexible boot 12 facilitating the flexing motion of the ankle.

(14) In a particular embodiment, the vamp 24, instep portion 28 and rear portion 30 are all integrally molded in a single piece, and the quarters 26 are attached thereto by a suitable fastening means. In one embodiment, the quarters 26 are attached to this single piece by stitching, as schematically illustrated by the stitch lines 60 in FIG. 1. Alternate methods to attach the quarters 26 to the remainder of the upper 22 are however also possible, and include adhesive and lamination for example. In the present embodiment, the upper 22 is thus formed of only three separate elements (i.e. the two quarters 26 and the single piece including the vamp 24, instep portion 28 and rear portion 30) which are easily assembled together, providing a relatively simple manufacturing process.

(15) In a particular embodiment, the quarters 26 overlap the remainder of the upper 22 only along edges thereof sufficient to allow the connection therebetween, as shown in FIG. 3. In an alternate embodiment, however, the quarters 26 completely overlap the remainder of the upper 22, i.e. the upper 22 includes a layer of flexible material beneath the overlaid quarters 26, to which the quarters 26 are connected, as shown in FIG. 2.

(16) The vamp 24, instep portion 28 and rear portion 30 are preferably made of a material having sufficient flexibility for a comfortable fit, an adequate abrasion resistant surface finish, and which can be easily formed to the desired shape. In one particular embodiment, the vamp 24, instep portion 28 and rear portion 30 are all made of ethylene vinyl acetate (EVA), optionally covered (e.g. laminated) with a layer of polyurethane to provide an improved surface finish.

(17) The quarters 26 are preferably made of a material having sufficient rigidity for providing proper support, an adequate abrasion resistant surface finish, and which can be easily formed to the desired shape. In one particular embodiment, the quarters 26 include a plurality of laminated layers, which include layers of at least one of expanded polypropylene (EPP) and poly(ethylene-co-methacrylic acid) (EMAA), also known as Surlyn. The layers also optionally include one or more layers of mesh or filament, preferably made of a plastic such as nylon, for improved rigidity.

(18) In an alternate embodiment, the quarters 26 can be made of a single layer of an adequate material, such as for example EPP or Surlyn.

(19) In a particular embodiment, the heel support 58 is integrally formed (such as by molding for example) with the outsole 16 to form a single integral piece, and the heel support 58 and outsole 16 are made of a rigid composite material, such as for example a material including carbon fiber. Such a construction provides improved support for the heel, particularly in tight turns, and provides for an improved energy transmission to the ice while skating.

(20) In another embodiment, the toe cap 18 may also be integrally formed with the outsole 16, in the same manner as the heel support 58, such as to form a single integral piece composed of the same material (such as a carbon fiber based material as noted above). Further, both the heel support 58 and the top cap 18 can be both integrally formed with the outsole 16, such as to form a single integral piece to which the rest of the boot 12 is attached.

(21) The embodiments of the invention described above are intended to be exemplary. Those skilled in the art will therefore appreciate that the foregoing description is illustrative only, and that various alternate configurations and modifications can be devised without departing from the spirit of the present invention. For example, the boot configuration of the present invention could be applied to types of boots other than skate boots. Accordingly, the present invention is intended to embrace all such alternate configurations, modifications and variances which fall within the scope of the appended claims.
