Description

TITLE: PROTECTIVE HOCKEY SOCK
FIELD OF THE INVENTION
[0001] This invention pertains generally to a protective sock for skaters, and more particularly to a protective sock for protecting a back of a lower leg of an ice hockey player from a penetrating or an abrading injury.
BACKGROUND

[0002] Shin guards used by ice hockey players serve as the primary protective equipment for protecting a player's lower leg from injury.
However, traditional shin guards only cover the front and sides of the leg leaving the calf exposed and vulnerable to lacerations from skate blades and hockey stick blades. The Achilles heel and the back of the knee are especially vulnerable to injury despite the protection afforded by the shin guards. A
laceration to these areas may cause permanent and debilitating injuries to leg muscles, blood vessels, nerves, ligaments, and tendons. Such injuries often endanger the player's ability to play hockey again, especially on a professional level thereby depriving the player from a livelihood.

[0003] Consequently, there is a need for a protective article of clothing that provides additional protection to the back of the lower legs of an ice hockey player that are not protected by existing protective hockey equipment. The present invention discloses a protective barrier element integratable into a traditional hockey sock that covers the exposed calf and Achilles heel, shielding the area from skate blade lacerations.
While protecting the back of the lower leg, the protective article of clothing still allows the player to maintain uninhibited mobility when worn. Additionally, the protective article of clothing works in conjunction with existing shin pads allowing the entire lower leg to be protected from skate and hockey stick blade injuries.
SUMMARY OF THE INVENTION

[0004] The following presents a simplified summary in order to provide a basic understanding of some aspects of the disclosed invention. This summary is not an extensive overview, and it is not intended to identify key/critical elements or to delineate the scope thereof. Its sole purpose is to present some concepts in a simplified form as a prelude to the more detailed description that is presented later.

[0005] The subject matter disclosed and claimed herein, in one aspect thereof, comprises a protective article of clothing that covers the lower leg of an ice hockey player from a knee to a heel. The protective article of clothing comprises a sock element that fits over and encapsulates a shin guard, and a protective barrier element highly resistant to penetrating injuries that is integrated into a back of the sock element. Additionally, the protective article of clothing may further comprise a variety of designs that match hockey team colors and logos.

[0006] Furthermore, the protective article of clothing maintains flexibility so that the ice hockey player's mobility remains unimpeded while still functioning as protective equipment. While still permitting the shin guard to protect a front of the lower leg, the protective barrier element provides flexible protection from lacerations to a previously unprotected back of the lower leg. Specifically, the protective barrier element substantially covers an Achilles tendon, a calf muscle, and a back of the knee, together with the adjacent blood vessels.

[0007] To the accomplishment of the foregoing and related ends, certain illustrative aspects are described herein in connection with the following description and the annexed drawings. These aspects are indicative of the various ways in which the principles disclosed herein can be practiced and all aspects and equivalents thereof are intended to be within the scope of the claimed subject matter.
Other advantages and novel features will become apparent from the following detailed description when considered in conjunction with the drawings.

DETAILED DESCRIPTION

[0011] Reference is now made to the drawings, wherein like reference numerals are used to refer to like elements throughout.
In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding thereof. It may be evident, however, that the novel embodiments can be practiced without these specific details. The intention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the claimed subject matter.

[0012] Referring initially to the drawings, PIGS. 1- 3 illustrate a protective article of clothing 100 for covering the lower leg of an ice skater.
Traditional ice hockey socks typically fit over a lower leg and a shin guard designed to protect a front of the lower leg. The traditional ice hockey socks are generally tight fitting flexible garments that extend from a heel to above a knee with a foot remaining un-encapsulated.
While the shin guard is held in place by the ice hockey sock, a back of the lower leg remains unprotected, as the sock is typically manufactured from a stretchable, but easily penetrated material such as cotton, nylon, rib-knit fabric, polyester, and the like, as is well known in the art.

[0013] The protective article of clothing 100 comprises a sock element 102 and a protective barrier element 116. The sock element 102 is typically an ice hockey sock comprising a front portion 104 and a back portion 106. However, the sock element 102 may also comprise any other lower leg covering usable as lower leg protection, such as but not limited to, an ice skating sock, a sports sock, and the like. The protective barrier element 116 is integrated into the back portion 114 of the sock element 102. The sock element 102 generally encapsulates the lower leg of an ice hockey player from the heel to above the knee. The sock element 102 is typically manufactured of a stretchable natural or synthetic material suck as cotton, nylon, rib-knit fabric, polyester, and the like, or of any other material or combination thereof known to one of skill in the art.

[0014] The sock element 102 further comprises an inside 108, an outside 110, a base 112, and a top 114. The base 112 comprises an opening for sliding the foot through and generally fits into the boot portion of a hockey skate. While ice hockey socks generally are designed to fit over a regular sock and do not encapsulate a foot, an embodiment where the sock element 102 may further comprises a foot encapsulating portion (not shown), or a stirrup strap (not shown) attached to the base 112 to operatively engage the foot of the user adjacent to the heel or sole area. All of these alternative embodiments are contemplated as well.

[0015] The protective barrier element 116 for protecting an Achilles tendon, a calf, and a back of a knee is generally a flexible protective material that is cut and/or laceration resistant. A particularly useful material for this purpose is a synthetic fabric, such as Kevlar0 or Vectrane fabric;
however any other suitable durable flexible material such as, but not limited to, plastic, high-tensile polymer, thermoplastic polyethylene fiber, polypropylene fiber, high-density microfiber, polyester fiber, natural rubber, butyl rubber, nitrile rubber, and the like, may be used without affecting the overall scope of the invention. The protective barrier element 116 may comprise either a single layer of material or, particularly in the case of synthetic fabrics, such as Kevlare or Vectrane fabrics, multiple layers of material having a stacked total thickness of approximately between 1/32 and ;1 inches.

[0016] As illustrated in FIG. 3, the protective barrier element comprises a top portion 118, a middle portion 120 and a bottom portion 122. The protective barrier element 116 may be generally rectangular in shape tapering approximately between 12 and 30 inches in height and approximately between 2 and 6 inches in width, so as to extend from the base 112 to the top 114 of the sock element 102. However, the shape of the protective barrier element 116 may be ovoid, conical, or irregularly shaped as well. For example, the protective barrier element 116 further comprises a first side 124 and a second side 126. The first side 124 and the second side 126 may further extend outward laterally in the middle portion 120, for better protecting the calf area. Furthermore, the first side 124 and the second side may extend to overlap or under lap the shin guard affording complete circumferential protection to the lower leg.
Similarly, either the top portion 118 and/or the bottom portion 122 may be the widest point as well.

[0017] The protective barrier element 116 is attachable to the back portion 106 of the sock element 102. The protective barrier element 116 is generally stitched into, or onto the back portion 106 of the sock element 102, on either the inside 108 or the outside 110. The protective barrier element 116 may be also attached by adhesive, radio-frequency welding, hot glue pressing, and the like, or by any other method as is known in the art without affecting the overall scope of the invention.

[0018] Alternatively, the back portion 106 of the sock element 102 may have a window (not shown) formed therein. In such instance, the material of the protective barrier element 116 will be formed to be of slightly larger outside dimensions than said window, so as to provide a perimeter portion of the barrier element 116 positionable in overlapping relation to said perimeter portion of the window, such that both portions are attachable to one another by stitching, or any of the other means of attachment disclosed in the previous paragraph, with the protective barrier element 116 being visible through the window.

[0019] Furthermore, the protective barrier element 116 may be used as an insert so that it is removably locatable within the sock element 102, such as in between layers of the sock material, or within a pocket (not shown) in the back portion 106 of the sock element 102. Such a pocket may be on either the inside 108 or the outside 110 of the sock element 102. The entrance to said pocket may be left open, or covered by a flap. The flap may be fastenable in a closed position by any suitable fastening means, including a zipper, or hook and loop fastening material.
The hook and loop material may be Velcro hook and loop fastening material.

[0020] Alternatively, a patch member (not shown) may be arranged in substantially complete overlying relation to the barrier element 116 so as to releasably attach the barrier element 116 to either the inside 108 or the outside 110 of the back portion 106 of the sock element 102. In such alternative embodiment, the patch member removably holds the barrier element 116 in place against the back portion 106 when attached thereto, but is detachable from the back portion 106 to release the barrier element 116 when, for example, it is desirable to dissociate the barrier element 116 from the sock member 102 for laundering of the latter. Buttons, snap fasteners, zippers, or hook and loop fastening material, including Velcro hook and loop fastening material, are examples of suitable releasable fastening means for selectively attaching the patch to the back portion 106 of the sock member 102.

[0021] Alternatively, the protective barrier element 116 may further comprise a flexible, highly durable, cut-resistant coating or film applied, or otherwise adhered, to either the inside 108 or the outside 110 of the back portion 106 of a prior art ice hockey sock. Application of such a coating or film may be, by way of non-limiting example, pattern dipping, spraying, or 3D printing of the coating or film material onto the back portion 106 of the sock element 102.
Suitable materials that may be applied in this manner include, without limitation, rubberized compounds, butyl rubber compounds, nitrile rubber compounds, all diluted by suitable organic solvents, which solvents evaporate after application, leaving a cut-resistant coating or film deposited and adhered onto the back portion 106.

[0022] In all embodiments described above, where there is, in use, a layer of material interposed between the barrier element 116 and the leg of a user of the sock element 102, it is preferable, but not essential, that such material be water proof, or at least water resistant.
This is to prevent, or at least mitigate against, the deleterious effects of water migration, typically in the form of perspiration emanating from the user, into the material of the barrier element 116.
This is particularly desirable where the material forming the barrier element 116 is a ballistic fabric such as Kevlare, as the accumulation of moisture therein is not only known to increase the fabric's weight and discomfort to a user, but may also decrease the resistance of such fabrics to puncturing and/or cutting. In embodiments where no layer of material is interposed between the barrier element 116 and the leg of a user, it may be sufficient to treat the actual material that makes up the barrier element 116, particularly where it is a fabric material, by applying a water resistant spray or coating to the surface of the barrier element 116 directed towards the user to prevent an unacceptable degree of moisture accumulation therein.
