Title: Ankle reinforcing device

Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to an ankle reinforcing device for the prevention of ankle injuries such as sprains or breaks. 
     Ankle injuries are not uncommon among those engaged in physical activities such as sports or dancing, or even just wearing high-heels. Many devices have been made available to help prevent ankle injuries. However, such devices have several drawbacks: they tend to be bulky and overly restrict movement of the foot. 
     Various ankle injuries can occur, but most involve lateral (outside) or medial (inside) sprains. Some athletes, such as professionals, college athletes, and some high-school athletes, have access to athletic trainers or others who can “tape” the athletes&#39; ankles; however, most people do not have that option. Reusable ankle support devices tend to be expensive and impractical for many athletes and dancers because of the drawbacks previously mentioned. 
     Some devices use adhesives directly on the wearer&#39;s skin, but most users prefer to avoid this practice for various reasons such as skin sensitivity and difficulty removing. Taping of ankles is usually done in such a way that adhesives do not come in direct contact with the skin. The proposed invention does not require any adhesive to come in contact with the skin. The disposable model is easily removed simply by cutting the fastening tape. The reusable model is easily removed simply by un-wrapping the fastening tape. 
     2. Description of Prior Art 
     Various types of ankle supports and braces are known in the prior act to provide means to prevent ankle injuries. 
     U.S. Pat. No. 3,357,425 issued to Morgan Dec. 12, 1967 discloses an adhesive support wrap to prevent ankle injuries adhered directly to the wearer&#39;s skin. 
     U.S. Pat. No. 4,345,590 issued to Nakajima Aug. 24, 1982 discloses a pre-cut adhesive support bandage which attaches directly to the leg and foot. 
     U.S. Pat. No. 4,522,044 issued to Lineberry, et al. Jun. 11, 1985 discloses a sock with ankle support woven into the sock. 
     U.S. Pat. No. 4,753,229 issued to Sutherland Jun. 28, 1988 discloses a reusable ankle brace with reinforcing straps attached to a shoe. 
     U.S. Pat. No. 5,217,431 issued to Toronto, et al. Jun. 8, 1993 discloses an ankle brace consisting of a boot. 
     U.S. Pat. No. 5,617,745 issued to Della Corte, et al. Apr. 8, 1997 discloses a support sock with an ankle stabilization section woven in. 
     U.S. Pat. No. 5,944,678 issued to Hubbard, et al. Aug. 31, 1999 discloses an ankle brace with elastic connections between the foot section and the upper portion. 
     It is apparent from the foregoing that the prior art fails to teach an ankle reinforcing device as described herein: possessing an underlying member having flexible areas which allow the wearer&#39;s foot to move up and down at the ankle during use; reinforcing members consisting of high tensile strength materials such as metal, fiberglass, carbon fiber, aramid fiber, or other high tensile strength material, which are integral with or attached to said underlying member and arranged in a radial pattern to simultaneously restrict movement of the ankle in the medial and/or lateral directions while forming a hinge at the ankle such that up and down movement of the foot at the ankle is not greatly restricted; means to optimally position said ankle reinforcing device; means to securely fasten said ankle reinforcing device to the foot and the leg; markings to facilitate the correct placement of said means to securely fasten said ankle reinforcing device to the foot and the leg; and means to increase friction between said ankle reinforcing device and the wearer&#39;s skin. Said ankle reinforcing device being either disposable (for one-time use) or reusable (for repeated use); some or all of the materials used therein having a high coefficient of friction on human skin, such as latex, nitrile or silicone; some or all of the materials used therein being hypoallergenic; some or all of the materials used therein being waterproof; said ankle reinforcing device being small enough to be worn inside a sock or shoe; and said ankle reinforcing device being able to be worn on a range of foot sizes. 
     SUMMARY OF THE INVENTION 
     An ankle reinforcing device is disclosed, comprising an underlying member; reinforcing members arranged to restrict movement of the ankle in the medial and/or lateral directions while allowing up and down movement of the foot at the ankle; means to securely fasten said ankle reinforcing device to the wearer&#39;s foot and the leg; means to position said ankle reinforcing device for optimal effectiveness; and means to increase friction between said ankle reinforcing device and the wearer&#39;s skin. Both disposable and reusable models are offered. 
     In practical use, the invention is placed on the wearer&#39;s foot in the same manner as putting on a sock, with positioning markings placed over the ankle joint. One or more fasteners are attached above the ankle joint. One or more fasteners are attached across the front of the foot, the back of the foot, and/or the bottom of the foot. Integral reinforcing members then limit movement of the wearer&#39;s ankle in the medial and/or lateral directions. Said reinforcing members are positioned to cross at the ankle, creating a hinge point so up and down movement of the foot at the ankle is allowed. The wearer is thus able to run, jump, and otherwise participate in physical activities according to his or her ability while reducing the likelihood of having an ankle injury. 
     One embodiment of the invention has reinforcing members on both the outside and the inside of the ankle, preventing lateral and medial ankle injuries. A second embodiment of the invention has reinforcing members only on the outside of the ankle, preventing lateral ankle injuries. Another embodiment of the invention has reinforcing members only on the inside of the ankle, preventing medial ankle injuries. 
     One embodiment of the invention uses adhesive tape to securely attach said ankle reinforcing device to the wearer&#39;s leg above the ankle and to the wearer&#39;s foot below the ankle. Another embodiment uses a self-adhering or cohesive bandage type wrap to secure said ankle reinforcing device to the wearer&#39;s foot and leg so it can be worn more than once. Another embodiment uses hook and pile type fasteners to secure said ankle reinforcing device to the wearer&#39;s foot and leg so it can be worn more than once. 
     In one embodiment, all or part of the materials that come in contact with the wearer&#39;s skin have a high coefficient of friction on human skin, such as latex, nitrile or silicone. For example, in one embodiment the entire underlying member is made of such material. In another embodiment said underlying member may be made of a natural material such as cotton, wool, etc., or synthetic fiber, allowing moisture to escape from the wearer&#39;s foot; and friction panels integral with or attached to the inside of said underlying member and/or integral with or attached to said reinforcing members may directly contact the wearer&#39;s skin. These embodiments serve to increase the effectiveness of the device in preventing ankle injuries. 
     The proposed invention can be installed very quickly by the user or by others, such as trainers or coaches. One embodiment incorporates markings to guide the installer in correctly positioning said means to securely fasten said ankle reinforcing device to the wearer&#39;s leg and foot. 
     Other aspects of the construction, arrangement and combination of the various parts of the invention whereby the desired objectives are obtained, as well as advantages of the invention, will appear from the following description in which the preferred embodiments are discussed in detail as illustrated by the accompanying drawings.
