Description

FIELD OF THE INVENTION

The present invention relates to athletic protective shields, and in particular to athletic shields that protect the user against cuts.

BACKGROUND OF THE INVENTION

Athletes often wear protective gear in sports where there is a potential for injurious contact. In ice hockey, the skate blade poses a cutting danger. This danger is significant given the sharpness of the skate blade and the high speeds at which hockey players skate on the rink and frequently collide with one another. Laceration by the skate blade, particularly of the lower leg including the calf and the Achilles tendon, has been known to sideline recreational and professional hockey players. With player size, speed, and skill increasing every year, the frequency of this type of injury is on the rise. For example, in the past, Erik Karlsson of the Ottawa Senators, Andre Markov of the Montreal Canadians, Kevin Bieksa of the Vancouver Canucks, and Dave Bolland of the Toronto Maple Leafs have all suffered severe skate cuts to the Achilles and/or calf area. Such injuries may have long-term consequences for a player's career and general health.
Ice hockey skates provide some protection for the lower-most portion of the Achilles tendon. However, the calf and the remaining portions of the Achilles tendon remain susceptible to laceration by the skate blade. Existing protective gear for the Achilles tendon and the calf often uses aramids or high molecular weight polyethylene to provide resistance to cuts by the skate blade. These materials are typically spun into a fiber and incorporated in a fabric that forms part of the hockey player's uniform.
While these materials may be somewhat harder to cut than cotton and other synthetic fabrics used for hockey uniforms, it is highly uncertain whether they would be able to protect the calf and the Achilles tendon from deep cuts by a sharpened skate blade in a collision between two hockey players moving at full-speed. Given the serious consequences of deep cuts by the skate blade which can severely damage the calf and the Achilles tendon, aramid or polyethylene-based protective fabrics may not provide the level of skate cut-protection desirable in a hockey calf and Achilles tendon protective shield.

DETAILED DESCRIPTION OF THE INVENTION

The protective shield of the present invention uses a web of interlocking loops as a protective element for the calf and the Achilles tendon. Such webs can be highly resistant to being cut by the skate blade during normal hockey conditions, and can be sufficiently flexible to conform to the contours of a body part such as the lower leg. In addition, webs of interlocking loops can be relatively light and breathable. The web of interlocking loops can be secured to a resilient support segment, which can fit over a body part of the user and hold the protective shield in place during athletic movement.
FIG. 1A shows an embodiment of the protective shield 100, worn on the lower leg of a user and viewed from the side. Protective shield 100 includes a protective segment 105 secured to a support segment 110. Protective shield 100 can have any suitable shape that is shaped and sized to fit over a body part of a user. In the embodiment shown in FIG. 1A, protective shield 100 is shaped as a hockey sock, i.e. a knee-high sock without the foot section. The hockey sock is in effect a sleeve intended to cover the region of the lower leg extending from about the ankle to about the area below the knee. In other embodiments, the protective shield can be shaped and sized to fit around different body parts such as the neck, the fore-arms, the upper-arms, the upper legs, and the abdomen.
As shown in FIG. 1A, protective shield 100 can be worn on the lower leg, with protective segment 105 covering and protecting at least a rear portion of the lower leg including at least a portion of the Achilles tendon and/or at least a portion of the calf.
Protective segment 105 can protect the user from cuts and other physical dangers. For example, in the case of ice hockey the protective segment can protect the player from being cut by the blade of the hockey skate. The protective segment can also help to distribute and attenuate blunt force impact. Protective segment 105 can be made up of a web of interlocking loops. FIG. 1B shows a magnified region of FIG. 1A, and shows interlocking loops 120 forming a web which makes up protective segment 105. Such webs can be flexible, able to conform to the contours of a user's body part, and relatively light weight. When the loops are made of a material that is resistant to being cut, the web of interlocking loops can provide a cut-resistant protective segment. When the loop material is strong enough to withstand slashing from a hockey skate blade during normal game conditions, the protective segment can be considered to be hockey skate cut proof.
The loops can include metal including but not limited to titanium, carbon steel, and stainless steel. The loops can be made wholly of metal. The loops can, alternatively or additionally, be formed using polymeric materials including but not limited to high molecular weight polyethylene, polypropylene, polyester or aramids. Not all loops need be identical. The web can be a mix of interlocking loops of metallic and non-metallic materials. When the loops are metallic, one or more of them can be welded to form unbroken loop(s). These loops can be stronger than open loops that are formed by simply bending a metal wire into a loop shape.
Protective segment 105 can alternatively or additionally be made of a metal mesh, which can be made of interlaced metal wires or stamped out from a metal sheet. Protective segment 105 can alternatively or additionally be made of a fabric made of threads of aramids, Kevlar™, Vectran™, polyesters, polyethelene, polypropylene, and high-density microfiber.
Support segment 110 can be made of fabric. The fabric can be resilient, including but not limited to fabrics including elastane, high grade Lycra™, and Spandex™ fibers. Support segment 110 can additionally or alternatively include other resilient materials such as rubber or silicone. Support segment 110 can include straps or laces. Support segment 110 can be shaped and sized to fit around a body part of the user, which can be, but is not limited to, the lower leg as shown in FIG. 1A. In embodiments where support segment 110 is made of a resilient material, support segment 110 can be sized and shaped so that it becomes stretched when protective shield 100 is worn around a body part such as the lower leg. The resilience of support segment 110, then, can hold protective shield 100 in place around a body part such as the lower leg during athletic movement such as skating. The resilience of the stretched support segment 110 can also tension protective segment 105 against the body to be protected, which can be the calf and/or the Achilles tendon as shown in FIG. 1A.
Protective segment 105 can be permanently secured to support segment 110 to form a unitary piece, such as protective shield 100. Any suitable means can be used to secure protective segment 105 to support segment 110; such means can include but are not limited to fusing, bonding, gluing, sewing, taping, or any combination of such. Protective segment 105 can also be releasably securable to support segment 110, using suitable means including but not limited to one or more hook-and-loop fasteners, one or more zipper, buttons, one or more laces, or any combination of such.
Although support segment 110 can tension the web of interlocking loops 120 of protective segment 105 when protective shield 100 is worn, the interlocking design can allow interlocking loops to retain the ability to move relative to one another when protective segment 105 is struck by an object such as the blade of another's skate. This relative movement can dissipate some of the striking blade's energy and can make it more difficult for the blade to cut through the web of interlocking loops. In this sense, interlocking loops 120 can be considered to be able to float relative to one another. This ability to float can apply to all embodiments of the present invention which comprise a web of interlocking loops.
When support segment 110 is made of a resilient material, while protective shield 100 is worn protective segment 105 can move relative to support segment 110 when protective segment 105 is struck by an object such as another's skate blade. Alternatively and/or in addition, when worn, protective shield 100 as a whole may be able to move relative to the body of the wearer when protective shield 100 is struck by an object such as another's skate blade. These relative movements can dissipate some of the striking blade's energy and can make it more difficult for the blade to cut through protective segment 105 and/or protective shield 100. In this sense, protective segment 105 and/or protective shield 100 can be considered to be floating or suspended relative to the body of the wearer. This property of being suspended or floating can apply to all embodiments of the present invention.
Several factors can contribute to making the protective shield comfortable to ware. These factors include, but are not limited to: relatively light weight of the protective shield; breathability of the protective segment and support segment materials; flexibility of the protective segment and/or the support segment allowing the protective shield to conform to the contours of the wearer's body and to fit snugly; relatively comfortable feel of the protective shield against the skin; and the ability of the protective shield to remain in place during vigorous athletic movement including, but not limited to, skating. These factors, to varying extents, can apply to all embodiments of the present invention.
FIG. 2 shows another embodiment of the protective shield 200, worn on the lower leg of a user and viewed from the side. Protective shield 200 can be made up of protective segment 105 secured to support segment 210. Support segment 210 can have a cuff 215 near its end that is to be worn near the knee. Cuff 215 can be a region of thicker fabric, folded fabric, stitched fabric, and/or otherwise strengthened or different material. Cuff 215 can have additional resilience to hold protective shield 200 in place around the lower leg, particularly during vigorous athletic movement such as ice staking. In addition, the thicker or reinforced material of cuff 215 can prevent the edge of support segment 210 from rolling onto itself under tension.
Hem 220 can have a structure and function similar to cuff 215. Protective segment 105 can be secured to support segment 210 along seam 205. The securing can be achieved using a suitable means including but not limited to fusing, bonding, gluing, sewing, taping or any combination of such.
FIG. 3 shows an embodiment of the protective shield 100, worn on the lower leg of a user and viewed from behind. Protective segment 105 can cover at least a part of the calf and a part of the Achilles tendon. Protective segment 105 is secured to support segment 110, which can fit around the lower leg, hold protective shield 100 in place during ice skating movement, and tension protective segment 105 against the rear portion of the lower leg.
FIG. 4 shows an example pattern of a web 400 of interlocking loops 405 that can be used for any of the protective segments discussed herein. In this example pattern, each loop 405 is interlocked with 4 adjacent loops. In general, any suitable pattern for a web of interlocking loops can be used. In other embodiments, each loop is interlocked with at least two other loops. In other patterns, loops can be interlocked with one another and with other elements including but not limited to plates and wires. In some embodiments, loops 405 can be of 4.0 or 7.0 ring size. Loops 405 can be made of grade 4 titanium, or other suitable grades of titanium. In addition, loops 405 can be made of 304 stainless steel or 316 stainless steel. Web 400 of interlocking loops 405 can comprise pieces of 21 gauge wire formed into interlocking circular loops of 7/32 inches diameter, with each circle being welded to form an unbroken loop. Other suitable loop materials, loop diameters and thicknesses, and web interlocking patterns can also be used.
FIG. 5 shows a cross-section of an embodiment of the protective shield 500, worn on the lower leg 520 of a user, as viewed from above. Protective shield 500 can have a protective segment 505 secured to a support segment 510. Protective segment 505 can be made of a web of interlocking loops. Protective segment 505 can be the similar to protective segment 105 described above. Support segment 505 can have a fabric layer 515 covering one side of the web of interlocking loops. When protective shield 500 is worn over lower leg 520, fabric layer 515 can be interposed between the skin of the user and the interlocking loops. Fabric layer 515 can increase comfort, and can be made of any other suitable material including but not limited to foam, mesh, and fabric containing elastane or Lycra™ fibers. Fabric layer 515 can be an extension of the support segment 510, or can be a different material secured to support segment 510 using any suitable method including fusing, bonding, gluing, sewing, taping, or any combination of such. In some embodiments, not shown, a fabric layer can cover the outside surface of protective segment 505 that faces away from the leg of the user. The fabric layers described above can be incorporated into any of the embodiments described herein.
When worn as part of an ice hockey uniform, protective shield 500 can be worn around lower leg 520, with protective segment 505 covering at least a portion of the calf 525 and/or a portion of the Achilles tendon. A regular hockey sock 530 can be worn over protective shield 500. In FIG. 5 protective shield 500 and hockey sock 530 are shown as spaced from leg 520 to clearly show each layer; when worn, protective shield 500 and hockey sock 530 can be tight against the leg 520 of the user. In addition, protective shield 500 and other parts of the athletic uniform can be worn in different orders against the user's body part. For example, other parts of the uniform can be worn between the user's leg and protective shield 500, and/or protective shield 500 can be the outermost layer worn over other parts of the uniform.
FIG. 6 shows an embodiment of the protective shield 600, worn on the lower leg of a user and viewed from behind. Protective shield 600 comprises protective segment 605 secured to support segment 610.
