Description
Background of the Invention
Among athletes and non-athletes alike the sprained ankle is one of the most common injuries. A wide variety of supports, braces, elastic bandages and the like have been devised to prevent or reduce the severity of ankle sprains but have met with little success. The non-athlete generally does little or nothing to prevent such sprains, while athletes frequently have their ankles taped by a trainer as a sprain prevention technique, as well as a technique allowing the athlete to perform in spite of a prior injury. This almost universal preventative technique of ankle taping is a relatively costly process both in terms of the trainer time required for the taping process and the material cost. Further, a poorly done ankle taping is almost totally ineffective. Current estimates of the cost to an athletic department are between one dollar and thirty cents and one dollar and fifty cents for each athlete taped.
Summary of the Invention
Among the several objects of the present invention may be noted the provision of an ankle support which may be easily applied by an inexperienced person, is of moderate cost, and has a long useful life; the provision of an ankle support to reduce the likelihood of a sprained ankle or to reduce the severity in the few cases where a sprain does occur; the provision of an ankle support useful in conjunction with ankle tapings on an already injured individual; and the provision of an ankle support which will reduce sidewise flexing of the ankle joint while allowing substantially unimpeded dorsiflexion thereof. These and other objects and advantageous features of the present invention will be in part apparent and in part pointed out hereinafter.
In general an ankle support has a main body portion for passing around the Achilles' tendon and along the inner and outer sides of the foot with a tongue portion extending from and integral with the main body portion for passing over a portion of the instep of the foot. A first strap portion also integral with and extending from the main body portion is located opposite the tongue portion to lap over the tongue portion and secure the support about the ankle. A stirrup portion depends from the main body portion intermediate the tongue and first strap portion of pass beneath the arch and sole of the foot, preventing upward movement of the main body portion. The main body portion along with the first strap portion and tongue portion are formed from different portions of the same sheet of multi-layer fabric, while the stirrup portion is formed from a separate piece of that same multi-layer fabric and joined to the main body portion in two regions along one edge thereof by stitching. Stiffening members sandwiched between the main body portion layers lie along the inner and outer sides of the ankle. The strap portion attaches to the main body portion by means of a contact fastener material such as Velcro. The support may be made of cloth-backed imitation leather or a canvas-like cloth material, for example, and in an alternate form the strap portion is made somewhat more narrow, and a second strap portion integral with and extending from the main body portion adjacent the tongue portion may also be provided with that second strap encircling the ankle above the region of the first strap portion.

The exemplifications set out herein illustrate a preferred embodiment of the invention in one form thereof and such exemplfications are not to be construed as limiting the scope of the disclosure or the scope of the invention in any manner.
Description of the Preferred Embodiment
Referring first to FIGS. 1 through 3, the ankle support is seen to include a main body portion 11 having a tongue portion 13 integral therewith and extending therefrom in one direction while extending in the other direction and also integral with the main body portion 11 is a first strap portion 15. Depending from the main body portion 11 intermediate the tongue 13 and strap 15 is a stirrup portion 17 which is attached as by stitching along the regions 19 and 21 to the main body portion 11. Directly above the stitched regions 19 and 21 are located two stiffening panels 23 and 25 of, for example, a compressed foam. A single panel extending throughout the support is sometimes preferred. The stiffening panel or panels are sandwiched between the two layers of fabric forming the main body portion as well as the tongue and strap. The stirrup portion 17 may be formed from a separate piece of that same two layer material. The inner surface of strap 15 has stitched thereto a strip 27 of contact fastener material, such as the monofilament hooks of a Velcro fastener, while the outer surface of the main body portion 11 has a strip 29 of contact fastener material, such as a Velcro pad. Pad 29 may extend along either or both the tongue and the main body portion and the strips 27 and 29 provide a great deal of latitude in the foot size to be accommodated.
The sheet of multi-layer fabric from which the body, tongue and strap portions are integrally formed may comprise first and second layers of cloth-backed imitation leather, such as Naugahyde superposed and stitched together about the periphery of the sheet, as illustrated in the embodiment of FIGS. 1 through 5, or may, as illustrated in FIGS. 6 and 7, comprise first and second layers of a canvas-like cloth, again superposed and stitched together about the periphery of the sheet. In either case, the support is free of elastic material, and the stirrup ends are typically inserted between the layers prior to stitching, as are the stiffeners 23 and 25.
In use, the user seats his heel firmly in the pocket about opening 31 formed between the back of the body portion and stirrup 17 and thereafter folds tongue 13 firmly over his instep, as illustrated in FIG. 4, and then laps the strap 15 over the tongue portion, joining those two portions by the contact fastener material, as illustrated in FIG. 5. The user may, for comfort, prefer to wear a sock underneath the support and in most cases will wear a shoe over the support with tight lacing of the shoe helping to minimize lateral slippage of the stirrup 17 beneath the foot.
Certain variations are illustrated in FIGS. 6 and 7 it being understood that these features may be freely chosen and interchanged between the illustrated versions of the support. The support of FIGS. 6 and 7 has strap 33 somewhat more narrow than the analagous strap 15 of FIGS. 1 through 5, and also has tongue portion 35 somewhat smaller than the analagous tongue portion 13 of FIGS. 1 through 3. A second strap portion 37 is formed integral with and extending from the main body portion 39 adjacent tongue portion 35 for tightening the support about an ankle above the region of the first strap portion 33. A pair of stiffening side panels or a single stiffening panel 41 may, as before, be sandwiched between the main body portion layers to lie along the inner and outer sides of the ankle to reduce sidewise flexing of the ankle joint while allowing substantially unimpeded dorsiflexion thereof.
Regions of contact fastener material, such as Velcro hooks 45 and 47, are attached to the inner surfaces of the first strap portion 33 and the second strap portion 37, with mating regions of contact fastener material, such as Velcro pads 49 and 51, on the outer surfaces of main body portion 39 so that the support may be adjustably tightened about any one of a range of sizes of foot. The one mating region of contact fastener material 51 overlies approximately the upper third of the stiffening side panel 43 while the other mating region of contact fastener material 49 overlies approximately the middle third of the other stiffening side panel so that when the support is properly positioned about an ankle, the first and second straps encircle the ankle to opposed senses with the second strap 37 lying above the first strap 45.
As in the embodiment of FIGS. 1 through 5, the stiffening side panel 41 may be about one-sixteenth inch thick to one-eighth inch thick compressed foam of a firmness about sixteen to eighteen. This firmness figure reflects the fact that the reticulated polyester polyurethane open pore foam from which the compressed foam is formed under heat was about sixteen to eighteen times as thick. Suitable materials are marketed under the Trademarks Scottfelt, as well as Ensolite by Uni-Royal. The latter material allows a heat laminating process to replace much of the illustrated stitching. Also as in the first version the stirrup portion 53 may be formed from the same multi-layer material with the ends thereof positioned between layers of the main body portion 39 prior to edge stitching thereof.
From the foregoing it is now apparent that a novel ankle support has been disclosed meeting the objects and advantageous features set out hereinbefore as well as others and that modifications as to the precise configurations, shapes and details may be made by those having ordinary skill in the art without departing from the spirit of the invention or the scope thereof as set out by the claims which follow.
