This application claims the benefit of U.S. Provisional Patent Application 60/690,105 (filed 13 Jun. 2005), the entire disclosure of which is hereby incorporated by reference herein.
FIELD OF THE INVENTIONThe present invention relates generally to equipment and apparel used during sporting activities, and more particularly to sporting equipment and apparel having beneficial protection and support characteristics.
BACKGROUND OF THE INVENTIONParticipants in many sporting activities are often subject to jarring impacts resulting form falls, collisions with objects, or even collisions with other participants. Sporting activities that involve participants moving at high speeds, such as skiing, snowboarding and ice skating, have the potential to be particularly dangerous in this respect. To mitigate the adverse effects of such impacts, a wide variety of protective equipment has been developed. Such protective equipment includes both rigid structural devices such as helmets and shin guards, as well as soft form-fitting padded garments, such as padded pants and jackets. Often, protective equipment is specifically designed for use in a particular sporting activity, such as a baseball catcher's chest protector or a hockey goalie's protective padding.
Furthermore, sports injuries are often sustained not only from jarring impacts, but also from overextending the natural capabilities of a participant's joints, muscles, or other anatomy. For example, significant injury often results when joints such as the knee joint are overextended or over-flexed. To reduce the likelihood of such injuries, braces and other orthopaedic devices have been developed that are intended to restrict the motion of a joint.
BRIEF SUMMARY OF THE INVENTIONConventional protective equipment designed to insulate an athlete from impact injuries often comprises bulky padding elements that are attached either directly to the athlete's body, or to a garment worn by the athlete. While such equipment is usable to protect against impact injuries, significant disadvantages exist. For example, many athletes find that such equipment is uncomfortable to wear, is bulky and unsightly, and is unduly restrictive of the athlete's movement. This is especially so for many orthopaedic devices designed to protect against joint injuries, such as knee injuries, since conventional devices often include hardware that is heavy, unsightly, expensive and uncomfortable to wear. Thus, in accordance with the foregoing, improved protective equipment and apparel has been developed to help mitigate and/or prevent injuries sustained by participants in sporting activities.

BRIEF DESCRIPTION OF THE DRAWINGSExample embodiments of the performance equipment and apparel disclosed herein are illustrated in the accompanying drawings, which are for illustrative purposes only. The drawings comprise the following figures, in which like numerals indicate like parts.
Disclosed herein are various embodiments of protective equipment and apparel having features that are particularly useful in reducing the risk of injury associated with sporting activities, such as skiing, snowboarding, skating, and the like. For example, in certain embodiments a garment is provided with an inner liner layer having padding elements secured thereto. The padding elements are positioned in the garment at locations that correspond to portions of the anatomy that are particularly vulnerable to impact injuries, such as the knees, elbows, shoulders and hips. In other embodiments. a knee support device is provided that provides resistance to potentially damaging movement of a knee joint. The knee support device is optionally integrated into a trousers that includes padding elements.
Example techniques used to secure the inner liner layer 12 and the exterior layer 16 together include sewing, stitching, gluing, and chemically bonding, although other techniques are used in other embodiments, such as the use of a zipper or a hook-and-loop type fastener. Optionally, multiple seams 18 are configured to form an enclosed region 20 between the inner liner layer 12 and the exterior layer 16, as illustrated in
The inner liner layer 12 and the exterior layer 16 have properties that are tailored to the application in which the multilayered garment 10 is intended to be used, among other things. For example, where the multilayered garment 10 is intended to be used during snow sports, such as skiing and snowboarding and the like, the exterior layer 16 is provided with a waterproof or water resistant surface that is lightweight and breathable, but that also provides the wearer with protection from wind chill and other inclement weather. Examples of materials that are used to form the exterior layer 16 include polyurethane-coated polyester and/or nylon, although other materials and coatings are used in other embodiments. Likewise, examples of materials that are used to form the inner liner layer 12 include polyester, fleece, elastic mesh and other materials that are particularly well suited to be worn against interior clothing layers, or against the skin.
Still referring to
In an example embodiment, the padding element 14 is a flexible high density open—or closed—cell polyurethane material, such as is available from Rogers Corporation (Rogers, Conn.) under the brand name PORON®. Polyurethane padding advantageously resists deformation over time, and decreases the peak force exerted on a body when used to cushion an impact. For example, in one embodiment the padding element 14 is capable of decreasing the peak force exerted on a body by at least about 10% as compared to an unpadded impact, more preferably by at least about 30% as compared to an unpadded impact, and most preferably by at least about 50% as compared to an unpadded impact. Polyurethane padding provides these mechanical properties without being excessively bulky or heavy, which is particularly advantageous for sporting apparel applications.
Other padding materials are used in other embodiments, such as shape memory foams or viscoelastic foams that are capable of form-fitting to the wearer's body and at least partially absorbing the mechanical shock associated when an impact occurs with another object. For example, in certain embodiments the padding material is disposed in a pouch filled with a shock absorbing material, such as a viscoelastic gel or a fluid, such as air. In modified embodiments, the padding element 14 comprises a laminated element having a plurality of layers of different materials. For example, in one such embodiment the padding element 14 is a layered element that comprises an inner viscoelastic foam layer positioned toward the wearer's body and an outer polyurethane layer positioned toward the garment exterior. In certain embodiments the padding element is formed by an injection molding process. In still other embodiments, the padding material includes one or more spring elements formed therein, such as a metallic spring element.
In certain embodiments wherein the pocket 24 includes an opening, such as the flap 28 illustrated in
Referring again to
As set forth herein, the pockets 24 and the padding elements 14 are included in a garment in regions that are particularly susceptible to injury during sporting activities. For example,
In one embodiment, the inner liner layer 12 is substantially coextensive with the exterior layer 16, such that the seams 18 joining these layers are at least positioned around openings in the garment. For example, for the jacket 40 illustrated in
In certain embodiments, the trousers includes a knee support device that provides resistance to potentially damaging movement of a knee joint, as well as to impacts against a knee joint.
The sleeve 105 has attached thereto one or more layers of padding elements that are configured to protect the knee against damaging impacts and/or to restrict potentially damaging movements of the knee. Rapid movement of the knee into certain positions has the potential to damage the tendons, ligaments and other anatomy of the knee. In contrast, slower movement of the knee into the same position is often accomplished without causing such damage.
As described herein, in certain embodiments the knee support device 100 includes more than one layer of padding elements. For example,
The orientation and shape of the radial padding elements 130 are configured to protect the frontal portion of the knee from impact injuries without significantly restricting knee movement. For example, in the illustrated embodiment the radial padding elements 110 have a triangular shape whereby a narrow portion of the triangle is oriented toward the kneecap protection element 132, and a wide portion of the triangle is oriented in the opposite direction.
In certain embodiments, as illustrated in
The example embodiments illustrated in
Still referring to the example embodiment illustrated in
As disclosed herein, the knee support device 100 is optionally configured to be used with the trousers 50 disclosed herein. For instance, as shown in the example embodiment illustrated in
The improved protective equipment and apparel disclosed herein has been developed to help mitigate and/or prevent injuries sustained by participants in sporting activities. For example, the padded garments disclosed herein help to cushion portions of the anatomy that are particularly vulnerable to impact injuries, such as the knees, elbows, shoulders and hips. Placing the padding elements on an interior liner layer instead of directly on the wearer's body, or directly on the garment exterior body, reduces both interference with the wearer's motion and the bulky appearance of a padded garment. Other protective equipment disclosed herein includes a variety of knee support devices that are configured to restrict knee movements that have the potential to damage the knee anatomy. For example, in certain embodiments positioning a flexible sleeve having compressible padding elements over the knee joint provides resistance to large angle and/or rapid knee flexing.
SCOPE OF THE INVENTIONWhile the foregoing detailed description discloses several embodiments of the present invention, it should be understood that this disclosure is illustrative only and is not limiting of the present invention. It should be appreciated that the specific configurations and operations disclosed can differ from those described above, and that the methods described herein can be used in contexts other than sporting equipment and apparel.
