Description
    CROSS-REFERENCE TO RELATED APPLICATIONS
  • [0001]
    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 INVENTION
  • [0002]
    The 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 INVENTION
  • [0003]
    Participants 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.
  • [0004]
    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 INVENTION
  • [0005]
    Conventional 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.

  • DETAILED DESCRIPTION OF THE INVENTION
  • [0028]
    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.
  • [0029]
    FIG. 1A illustrates a cross-sectional view of a portion of a multilayered garment 10 that includes an inner liner layer 12 that is configured to be worn adjacent to a wearer's body, and an exterior layer 16 that provides the outer surface of the multilayered garment 10. The inner liner layer 12 and the exterior layer 16 are secured together at one or more seams 18 that are positioned at appropriate locations on the multilayered garment 10. In one embodiment, the positioning of the seams 18 depends on the portion of the body over which the multilayered garment 10 is to be worn, such as the upper body (for example, for a jacket), the lower body (for example, for a trousers), the feet (for example, for socks), the hands (for example, for gloves) or the head (for example, for a beanie).
  • [0030]
    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 FIG. 1A. In a modified embodiment, the seams 18 are releasable, such as provided by a hook-and-loop attachment system, thereby allowing the inner liner layer 12 to be separated from the exterior layer 16.
  • [0031]
    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.
  • [0032]
    Still referring to FIG. 1A, a flexible cover 22 is attached to the inner liner layer 12 so as to form a pocket 24 in which a padding element 14 is positioned. In an example embodiment, the flexible cover 22 comprises a lightweight material that is capable of being sewn or otherwise affixed to the inner liner layer 12 at seams 26. For instance, in one embodiment the flexible cover 22 comprises the same material as the inner liner layer 12, although different materials are used for the flexible cover 22 and the inner liner layer 12 in other embodiments. In one embodiment, the flexible cover 22 comprises an elastic textile, such as an elastic mesh material. The flexible cover 22 optionally includes an opening, such as provided by the flap 28 illustrated in FIG. 1A. In an example embodiment, pockets 24 are formed in regions of the garment that are particularly susceptible to collisions, such as the elbows, the shoulders, the ribs, the clavicle, the tailbone, the knees, the hips, and other regions of the body.
  • [0033]
    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.
  • [0034]
    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.
  • [0035]
    In certain embodiments wherein the pocket 24 includes an opening, such as the flap 28 illustrated in FIG. 1A, the padding element 14 is removable from the pocket 24. This configuration advantageously allows the padding element 14 to be replaced if worn, if a different size padding element is desired, or if the garment 10 is to be washed without washing the padding element 14. While the pocket 24 is illustrated with a flapped opening FIG. 1A, other types of openings are used in other embodiments, such as the hook-and-loop opening 30 illustrated in FIG. 1B. In modified embodiments, such as embodiments wherein the pocket 24 does not include an opening, the padding element 14 is secured within the pocket 24, such as by being affixed to the inner liner layer 12 and/or the flexible cover 22. In such embodiments, the padding element is secured by using an adhesive, by sewing, or by another technique. This configuration advantageously reduces the likelihood that the padding element 14 has excessive movement within the pocket 24, or becomes folded onto itself, or is otherwise disturbed in the pocket 24.
  • [0036]
    Referring again to FIG. 1B, a modified multilayered garment 32 is illustrated that includes a rigid shell 34 that is positioned in the pocket 24 with the padding element 14. In the illustrated embodiment, the rigid shell 34 is coupled to the exterior side of the padding element 14. In other embodiments the rigid shell is placed elsewhere within the pocket 24, such as on the interior side of the padding element 14, or within the padding element 14. The rigid shell 34 is configured to provide additional protection for regions of the body that are particularly susceptible to damaging impacts, such as the knees and the elbows. In such embodiments the rigid shell 34 has a shape that approximates the shape of the underlying anatomy that is to be protected. As illustrated, the rigid shell 34 is configured to cover a smaller area than the padding element 14 in certain embodiments, thereby preventing the garment 32 from becoming excessively heavy due to the rigid shell 34. In one embodiment that rigid shell 34 comprises a molded plastic element, although other materials are used in other embodiments.
  • [0037]
    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, FIGS. 2A and 2B illustrate front and rear views (respectively) of an example jacket 40 that includes padding elements in a shoulder region 42, a clavicle region 44, a rib region 46, and an elbow region 48. The padding elements in the elbow region 48 optionally include both a larger padding element 14, and a smaller rigid shell 34. In the illustrated example embodiment, the padding elements in the rib region 46 are optionally provided in the form of multiple parallel elongate elements, thereby allowing the jacket 40 to retain substantial flexibility in the rib region 46, thus helping to avoid giving the jacket an unduly bulky or rigid feel to the wearer, and helping to avoid giving the jacket a padded outward appearance. In modified embodiments, additional padding elements are positioned in other regions of the jacket 40, such as the lumbar region, or fewer padding elements are used. However, regardless of how many padding elements are used, positioning the padding elements 14 in pockets 24 that are secured to the inner liner layer 12 advantageously helps to prevent to padding elements from moving substantially from the respective body regions for which they are intended to protect.
  • [0038]
    FIGS. 3A and 3B illustrate front and rear views (respectively) of an example trousers 50 that includes padding elements in a hips region 52, a tailbone region 54, and a knee region 56. The padding elements in the knee region 56 optionally include lateral padding elements 56 a, frontal padding elements 56 b, and a kneecap rigid shell 56 c. As with the jacket 40, additional padding elements are optionally positioned in other regions of the trousers 50, such as the buttocks region, or fewer padding elements are used.
  • [0039]
    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 FIGS. 2A and 2B, the seams 18 in such an embodiment are at least located around the wrist openings 60, around the neck opening 62, around the waist opening 64, and along the chest opening 66. For the trousers 50 illustrated in FIGS. 3A and 3B, the seams 18 in such an embodiment are at least located around the ankle openings 68 and around the waist opening 70. In these embodiments, additional seams are optionally positioned elsewhere in the garment to provide further durability.
  • [0040]
    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. FIGS. 4A-4F illustrate example embodiments of a knee support device 100 that is compatible with the trousers disclosed herein, or that is usable independently of a trousers. The knee support device 100 comprises a tubular sleeve 105 configured to be positioned over the wearer's knee. In an example embodiment the tubular sleeve 105 comprises an expandable and structurally supportive material, such as neoprene foam or polyurethane foam, thereby allowing the sleeve 105 to fit snugly over the knee, and to resist twisting, sliding or other movement away from the wearer's knee joint. The tubular sleeve 105 optionally includes adjustable straps that allow the knee support device 100 to be placed on the wearer with an adjustable tightness. In such embodiments, the straps include hook-and-loop type fasteners, snaps, buckles or other mechanisms that allow the tightness of the straps to be adjusted.
  • [0041]
    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.
  • [0042]
    FIG. 4A provides a front view of a knee support device 100 that includes a first layer of lateral padding elements 110 that are positioned on lateral regions of the tubular sleeve 105. In an example embodiment, the lateral padding elements 110 comprise an open—or closed—cell polyurethane foam, although other padding materials, such as viscoelastic shock absorbing materials, are used in other embodiments. The lateral padding elements 110 are secured to the tubular sleeve 105 using an adhesive, although other attachment mechanisms are used in other embodiments, such as by sewing, by using a hook-and-loop type attachment system, or by stapling. The lateral padding elements 110 are shaped and positioned to contact and compress against each other as the knee is flexed, thereby providing resistance to rapid flexing of the knee and/or to over-flexing of the knee. This reduces the likelihood that these movements cause injury to the knee anatomy, such as injury to the anterior cruciate ligament. The lateral padding elements 110 also advantageously provide the lateral portion of the knee with protection from impact injuries.
  • [0043]
    FIG. 4B illustrates a side view of the knee support device 100 of FIG. 4A, with the front of the knee support device 100 facing to the right. A plurality of lateral padding elements 110 are positioned on the side of the sleeve 105. Although four lateral padding elements 110 are illustrated on each side of the knee support device 100 in FIGS. 4A and 4B, more or fewer padding elements are used in other embodiments. In the example embodiment illustrated in FIG. 4B, the knee support device 100 includes a seam 112 at which one or more pieces of expandable material are joined to form the tubular sleeve 105.
  • [0044]
    As described herein, in certain embodiments the knee support device 100 includes more than one layer of padding elements. For example, FIG. 4C illustrates a front view of the knee support device 100 of FIG. 4A, further including a second layer of front radial padding elements 130 that are positioned radially around a kneecap protection element 132. In an example embodiment, the radial padding elements 130 and the kneecap protection element 132 comprise the same material as the lateral padding elements 110, although other protective materials and/or padded materials are used in other embodiments. For example, in a modified embodiment the kneecap protection element 132 includes a rigid shell, such as the rigid shell 34 illustrated in FIG. 1B. The rigid shell is optionally configured to extend below the knee, such as to the wearer's shin, thereby providing additional impact protection to the shin as well as the kneecap. The radial padding elements 130 are affixed to the tubular sleeve 105 and/or the lateral padding elements using an adhesive, although other techniques for affixing these elements are used in other embodiments.
  • [0045]
    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. FIG. 4D illustrates a side view of the knee support device 100 of FIG. 4C, with the front of the knee support device 100 facing to the right.
  • [0046]
    In certain embodiments, as illustrated in FIG. 4E, a third layer of lateral support elements 120 are positioned over the tubular sleeve 105 and/or the lateral padding elements 110. In certain embodiments, the lateral support elements 120 comprise a padding material, such as a neoprene padding or a polyurethane padding. In such embodiments the lateral support elements 120 provide additional resistance to rapid flexing of the knee and/or to over-flexing of the knee, and additional protection against impact injuries. In a modified embodiment, the lateral support elements 120 comprise a more rigid structure, such as a flexible plastic or metallic element. The flexible plastic or metallic elements are optionally enclosed in a sheath that is affixed to the sleeve 105 and/or the lateral padding elements 110. The lateral support elements 120 are configured to advantageously reduce potentially damaging lateral movement of the knee.
  • [0047]
    FIG. 4F shows a side view of the knee support device of FIG. 4E, with the front of the knee support device 100 facing to the right, and indicates that in an example embodiment the lateral support elements 120 are positioned in three rows that are substantially parallel to the seam 112. More rows or fewer rows of lateral support elements 120 are used in other embodiments. Additionally, in other embodiments the lateral support elements 120 are configured to extend substantially uninterrupted across the length of the tubular sleeve 105.

    The example embodiments illustrated in FIGS. 4A-4F illustrate example embodiments of a knee support device 100 having one or more layers of lateral padding elements 110, lateral support elements 120, radial padding elements 130, and kneecap protection elements 132. However, other embodiments comprise other padding elements that are positioned on the sleeve using other configurations. For example, FIG. 5A is a side view of a modified knee support device 150 with the front of the knee support device 150 facing to the right, and FIG. 5B is a rear view of the modified knee support device 150 of FIG. 5A. The modified knee support device 150 comprises a tubular sleeve 155 having a plurality of padding elements attached thereto. The padding elements include a pair of upper padding elements 160 that are separated from each other, a pair of central padding elements 162 that are separated from each other, and a pair of lower padding elements 164 that are separated from each other. In an example embodiment, the padding elements are secured to the tubular sleeve 155 using an adhesive, although other securing methods are used in other embodiments.
  • [0049]
    Still referring to the example embodiment illustrated in FIGS. 5A and 5B, the pairs of padding elements are shaped and positioned in a substantially symmetrical configuration about a center axis 157 of the tubular sleeve 155. Furthermore, the pairs of padding elements are relatively narrow in a rear-facing region 170 of the tubular sleeve 155, and are relatively wide in a side-facing region 172 of the tubular sleeve 155. The upper, central and lower padding elements contact each other in the side-facing region 172 of the tubular sleeve 155, but are separated from each other in the rear-facing region 170 of the tubular sleeve 155. The pairs of padding elements extend between the rear-facing region 170 and the side-facing region 155 of the tubular sleeve in the illustrated configuration. The relative positions, sizes and shapes of the padding elements cause the element to become compressed against each other in the rear-facing region 170 of the modified knee support device when the knee is flexed. This advantageously provides a resistance to knee flexion that is relatively small when the knee is slightly bent, but that increases as the knee is bent to larger angles.
  • [0050]
    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 FIGS. 5A and 5B, the knee support device 150 includes fasteners 174, such as hook-and-loop type fasteners, that are usable to secure the knee support device 150 to a corresponding fastener included on the inner liner layer 12 of the trousers 50. An example embodiment of this configuration is illustrated in FIG. 6, which shows a partial cutaway front view of a trousers 50 having an exterior layer 16 and an inner liner layer 12. A knee support device 180 is secured to the inner liner layer 12 using fasteners 174. In a modified embodiment, an upper portion of the knee support device 180 is secured to the inner liner layer 12, and a lower portion of the knee support device 180 is secured to an inner portion of the exterior layer 16. In certain embodiments, the exterior layer 16 of the trousers 50 optionally includes a closable opening, such as a zippered opening, in the knee region of the trousers that is used to access a knee support device 180 positioned therein, regardless of whether the knee support device 180 is coupled to the trousers 50, or is simply placed over the wearer's knee.

    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.
