The present invention relates to a skate boot having an inner liner with an abrasion resistant cover, layer, patch, or overlay made of a material that has more abrasion resistance than the remaining material of the inner liner.
As is well known in the art, a skate boot for an ice hockey or roller hockey player may comprise an outer shell made of different layers and an inner liner or inner lining for covering the inner surface of the outer shell. The inner liner has an outer surface that is mounted to the inner surface of the outer shell and an inner surface adapted to contact the player's foot or the sock covering the player's foot.
The inner liner may be made of a layer of soft material such as a sheet of polyester laminated with a layer of foam, or of a layer of fabric made from nylon fibers.
Because of the repetitive flexing motions in the ankle region of the hockey player, the hockey sock covering the leg pad worn by the player and/or the boot tongue repetitively contact the upper medial and lateral inner regions of the inner liner and these portions are therefore exposed to much more friction and may eventually be partially or entirely be torn, abraded or damaged. This constant rubbing of the tongue and/or leg pad covered by the hockey sock is mostly concentrated to the upper medial and lateral inner regions of the inner liner around the first and second lace openings or eyelets of the skate boot, extending backwards from the lace openings or eyelets a few centimeters depending on the size of the skate boot.
There is therefore a need in the industry for a skate boot having an inner liner that has one or more overlays, coverings, layers or patches provided on the upper inner regions of the inner liner and made of a material that has more abrasion resistance than the remaining material of the inner liner.
As embodied and broadly described herein, according to a broad aspect, the invention provides a skate boot for enclosing afoot of a hockey player, the player's foot having a heel, an ankle with a medial side and a lateral side, and medial and lateral sides, the skate boot comprising: (a) an outer shell having outer and inner surfaces, the outer shell comprising a heel portion for receiving the heel of the player's foot, an ankle portion for receiving the ankle of the player's foot, the ankle portion of the outer shell comprising a medial side having a medial upper edge and a lateral side having a lateral upper edge, and medial and lateral side portions for receiving the medial and lateral sides of the player's foot; and (b) an inner liner made of a first material and comprising an outer surface mounted to the inner surface of the outer shell, an inner surface adapted to contact the player's foot or a sock covering the player's foot, an ankle portion comprising a medial upper edge, a medial upper inner region, a lateral upper edge and a lateral upper inner region, wherein one of the medial and lateral upper inner regions of the inner liner comprises an overlay made of a second material having more abrasion resistance than the first material of the inner liner.
According to another broad aspect, the invention provides a skate boot for enclosing afoot of a hockey player, the player's foot having a heel, an ankle with a medial side and a lateral side, and medial and lateral sides, the skate boot comprising: (a) an outer shell having outer and inner surfaces, the outer shell having a heel portion for receiving the heel of the player's foot, an ankle portion for receiving the ankle of the player's foot, the ankle portion of the outer shell comprising a medial side having a medial upper edge and a lateral side having a lateral upper edge, and medial and lateral side portions for receiving the medial and lateral sides of the player's foot; and (b) an inner liner made of a first material and comprising an outer surface mounted to the inner surface of the outer shell, an inner surface adapted to contact the player's foot or a sock covering the player's foot, an ankle portion comprising a medial upper inner region and a lateral upper inner region, and an overlay at least partially covering one of the medial and lateral upper inner regions of the ankle portion of the inner liner, the overlay being made of a second material having more abrasion resistance than the first material of the inner liner.

The skate boot 4 has an outer shell 6 for receiving the player's foot, the outer shell 6 having an outer surface 8 and an inner surface 10, a toe cap 12 made of a rigid material for protecting the player's toes, a tongue 14 extending upwardly and rearwardly from the toe cap 12 for covering a forefoot of the player's foot, an inner liner 16 having an outer surface 18 mounted to the inner surface 10 of the outer shell 6 and an inner surface 20 adapted to contact the player's foot or a sock covering the player's foot, a footbed 22, an insole 24, an outsole 26, an ice skate blade holder 28 and an ice skate blade 29. The footbed 22 has an upper surface for facing the plantar surface of the player's foot. The outsole 26 has an upper surface on which the sole portion of the outer shell 6 (e.g. the insole 24) may be affixed and a lower surface on which the blade holder 28 is mounted.
The outer shell 6 may be made of a thermoformable material. As used herein, the expression “thermoformable material” refers to a material that is capable of softening when heated and of hardening again when cooled. Some non-limiting examples of different types of thermoformable material comprise ethylene vinyl acetate (EVA) foam, polyethylene foam, polystyrene foam, polypropylene foam and thermoformable materials sold under the trade-marks MEGABIX®, SURLYN®, SONTARA®, FORMO500®, BYLON®. MOSOCA® and NYLON® 66.
The outer shell 6 is thermoformed such that it comprises a heel portion 30 for receiving the heel of the player's foot, an ankle portion 32 for receiving the ankle of the player's foot, the ankle portion 32 comprising a medial side 34 having a medial upper edge 36 and a medial upper region 38, a lateral side 40 having a lateral upper edge 42 and a lateral upper region 44, and a rear portion 46 for receiving the rear side of the ankle, and medial and lateral side portions 48, 50 for receiving the medial and lateral sides of the player's foot, the medial and lateral side portions 48, 50 having medial and lateral upper edges 52, 54. The medial and lateral side portions 48, 50 of the outer shell 6 extend forwardly from the heel and ankle portions 30, 32. The heel portion 30, ankle portion 32 and medial and lateral side portions 48, 50 form afoot-receiving cavity that conforms to the general shape of the player's foot.
The heel portion 30 of the outer shell 6 may be thermoformed such that it is substantially cup-shaped for following the contour of the player's heel.
The medial side 34 of the ankle portion 32 of the outer shell 6 may have a medial cup-shaped depression for receiving the medial malleolus and the lateral side 40 of the ankle portion 32 of the outer shell 6 may have a lateral cup-shaped depression for receiving the lateral malleolus. The lateral depression is located slightly lower than the medial depression for conforming to the morphology of the player's foot.
The rear portion 46 of the ankle portion 32 may be thermoformed such that it follows the lower part of the rear side of the player's foot.
The medial and lateral side portions 48, 50 of the outer shell 6 may be thermoformed such that they each define an inner surface that generally follows the contour of the side of the player's foot.
The outer shell 6 also comprises a tendon guard 56 for facing at least partially the upper part of the rear side of the ankle. The tendon guard 56 allows backwards flexion of the ankle when the player's foot moves towards full extension. The tendon guard 56 may be made of silicone or may be made by injection molding using polyester, polyurethane, polyamide, or other suitable thermoplastics. The selected material may have enough flexibility to allow the tendon guard 56 to flex rearwardly when pressure is applied on it while it should also have enough resiliency to allow the tendon guard 56 to return to its initial position when pressure is no longer applied on it.
The skate boot 4 may also comprises medial and lateral lace members 58, 60 mounted to the medial and lateral upper edges 52, 54 of the medial and lateral side portions 48, 50 of the outer shell 6. The medial and lateral lace members 58, 60 may be made of fabric, textile, leather or plastic and comprise a series of medial and lateral apertures 62, 64 for receiving a lace. Eyelets may be punched into the lace apertures 62, 64 of lace members 58, 60.
The lace members 58, 60 can be mounted to the medial and lateral upper edges 52, 54 of the medial or lateral side portions 48, 50 of the outer shell 6 via any method known in the art such as stitching, overmolding, thermal bonding, high-frequency bonding, vibration bonding, piping, adhesive, or any combination thereof. In yet other embodiments, the lace members can form an integral part of the outer shell 6. In another embodiment, the lace members may be omitted and lace apertures and eyelets may be rather provided along the medial and lateral upper edges of the medial and lateral side portions of the outer shell. Medial and lateral bands or overlays may then be added to the outer shell in order to add rigidity to the skate boot in the lace regions.
As indicated previously, the skate boot 4 has the inner liner 16, which can be mounted to the outer shell 6 by lamination, stitches, glue, needles, overmolding, thermal bonding, high-frequency bonding, vibration bonding, ultra-sonically bonded, or the like.
The inner liner 16 is made of a first material and comprises at least one covering, layer, patch or overlay made of a second material having more abrasion resistance than the first material of the inner liner.
The inner liner 16 may be made of different layers, for example an inner layer that is made of an air-pervious fabric and has an inner surface to contact the player's foot or sock in use, an intermediate cushioning layer made of a resilient cushioning material, and an outer layer that is co-extensive with the inner layer and cushioning layer and that is made of a water impervious material. The air-pervious fabric may be made of nylon fabric. The resilient cushioning material may be made vinyl foam.
In other examples, the inner liner 16 may be made of one or more layers of materials such as: anti-microbial, anti-fungal polypropylene, polyester or polyester blend having a polyester or cotton backing or the like; fabric or nonwoven made from corn fibers or a blend of corn fibers with acetate, polyvinyl acetate or polyester fibers; synthetic leathers; polyester fabrics; nonwoven fabrics, nonwoven wool blend; polyester fabric with an active carbon compound bonded to the polyester; or sanded polyester microfiber material.
In another example, the inner liner 16 may be made of a layer of soft material such as a sheet of polyester laminated with a layer of foam, or of a layer of fabric made from nylon fibers. The inner liner 16 may also be made of brushed nylon fabric, nylon mesh, polyester mesh or synthetic leather.
Referring to
The inner liner 16 is made of a first material and comprises at least one covering, layer, patch or overlay made of a second material having more abrasion resistance than the first material of the inner liner, the overlay being located in an inner region of the liner 16 that is more exposed to friction from the tongue and/or leg pad covered by hockey sock. For example, the inner liner may have medial and lateral overlays 86, 88 generally covering the medial and lateral upper inner regions 68, 74 of the inner liner 16. The medial and lateral upper inner regions 68, 74 of the inner liner 16 may each be seen as a region occupying a substantial portion of the upper of the medial and lateral inner surfaces of the ankle portion 66 delimited by the upper edge and the front edges at both upper corner sides (see the trapezoids shown as broken lines in
The medial overlay 86 has upper, front, lower and rear edges 86UE, 86FE, 86LE, 86RE and the lateral overlay 88 has upper, front, lower and rear edges 88UE, 88FE, 88LE, 88RE, the upper edge 86UE of the medial overlay 86 being located adjacent the medial upper edge 70 of the inner liner ankle portion 66, the front edge 88FE of the medial overlay 86 being located adjacent the medial front edge 72 of the inner liner ankle portion 66, the upper edge 88UE of the lateral overlay 88 being located adjacent the lateral upper edge 76 of the inner liner ankle portion 66 and the front edge 88FE of the lateral overlay 88 being located adjacent the lateral front edge 78 of the inner liner ankle portion 66. As is best seen in
While the inner liner 16 has medial and lateral overlays 86, 88, it is understood that one overlay may be omitted such that the inner liner only comprises one overlay located on the inner region that may be more exposed to friction (the lateral inner region for example).
The medial and lateral overlays 86, 88 may be mounted or affixed to the medial and lateral upper inner regions 68, 74 of the inner liner 16 using any method known in the art such as lamination, stitching, gluing, needling, overmolding, thermal bonding, high-frequency bonding, vibration bonding, ultra-sonically bonding or any combination thereof.
Moreover, the medial and lateral overlays 86, 88 may be made of any suitable material offering more abrasion resistance than the remaining material of the inner liner 16, such as thermoplastic polyurethane, polyurethane, denier nylon, denier cordura, ballistic nylon, rubber or neoprene.
For example, the medial and lateral overlays 86, 88 may be made of a thermoplastic to polyurethane film or layer bonded to the inner surface 20 of the inner liner 16 by high-frequency bonding at a temperature between 90° C. and 100° C. and at a pressure between 4 and 5 kg/cm2 for about two minutes with a cooling period of about one minute.
The medial and lateral overlays 86, 88 may each have a thickness between 0.3 mm and 0.7 mm.
