ATHLETIC PROTECTIVE SHIELD
A protective shield for a lower leg of an ice skater is provided. The protective shield comprises a protective segment and a support segment to which the protective segment is secured. The protective segment comprises a web of interlocking metal loops. The protective segment is shaped and sized to fit over at least a rear portion of the lower leg including at least a portion of an Achilles tendon and at least a portion of a calf. The support segment is shaped and sized to fit around the lower leg, and is resilient to hold the protective shield in place around the lower leg during skating and to tension the protective segment against the rear portion of the lower leg.
The present invention relates to athletic protective shields, and in particular to athletic shields that protect the user against cuts.
BACKGROUND OF THE INVENTIONAthletes 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.

According to another aspect of the present specification there is provided a protective shield for a lower leg of an ice skater, the protective shield comprising a protective segment and a support segment to which the protective segment is secured. The protective segment comprises a web of interlocking metal loops made of steel or titanium. The protective segment is shaped and sized to fit over at least a rear portion of the lower leg including at least a portion of a calf and at least a portion of an Achilles tendon. The support segment comprises elastane and is permanently secured to the protective segment to form a unitary hockey sock shaped and sized to fit around the lower leg. The support segment is resilient to hold the protective shield in place around the lower leg during skating and to tension the protective segment against the rear portion of the lower leg.
For a better understanding of the various embodiments described herein and to show more clearly how they may be carried into effect, reference will now be made, by way of example only, to the accompanying drawings.
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.
As shown in
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.
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
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.
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.
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
The above-described embodiments of the invention are intended to be examples of the present invention and alterations and modifications may be effected thereto, by those of skill in the art, without departing from the scope of the invention which is defined solely by the claims appended hereto.
