DETAILED DESCRIPTION

An exemplary cast cover may be used to cover a short arm cast, such as the type used to immobilize a wrist fracture, for example. The cast cover may be used by an athlete who desires to participate in an athletic contest while wearing a cast, for example.
As shown in FIGS. 1 and 2, an exemplary cast cover 10 may include a shell 20. The shell 20 may be adapted to be secured around a cast worn by a user. The shell 20 may include an opening 50 adapted to allow a body part to extend therethrough. For example and without limitation, the opening 50 may be adapted to allow a user to extend a thumb 6 through opening 50 when the cast cover 10 is worn over the user's forearm 2 and a cast 4 (see, e.g., FIG. 3).
In an exemplary embodiment, the shell 20 may generally be in the form of a flat pocket having an opening edge 40. The opening edge 40 may be secured (shut) using at least one fastening device such as, but not limited to, one or more sets of hook and loop closures. In the exemplary embodiment depicted in FIG. 1, stitching lines 42, 44 indicate where hook and loop fasteners are sewn within the pocket proximate to the opening edge 40. Other embodiments may include one or more openings at alternative positions on the shell, such as on a side or on a different edge. Further, the opening may not include a fastening device in some embodiments. In such an embodiment, the shape and/or size of the opening may be adapted to retain objects located within the shell 20.
In an exemplary embodiment, the shell 20 may include features adapted to secure the cast cover 10 around a cast. In an exemplary embodiment, shell 20 includes four sets of hook and loop fasteners. The loop portions 22, 24, 26, 28 are sewn to the shell 20. Hook portions 32, 34, 36, 38 are also sewn to shell 20, but each extends beyond shell 20 in the form of straps. Each of the hook portions 32, 34, 36, 38 corresponds to one of the loop portions 22, 24, 26, 28 such that the cast cover may be wrapped around a cast and secured by coupling the corresponding portions as shown in FIGS. 3, 6, and 9.
While an exemplary embodiment depicted in FIG. 1 includes four sets of hook and loop fasteners, it is within the scope of the invention to include more or fewer fasteners. Further, the fasteners may not extend beyond the shell 20 in some embodiments. In such an embodiment, the cast cover 10 may wrap around the cast and fasten to itself using the provided one or more fasteners. In addition, fasteners other than hook and loop fasteners (such as, but not limited to, one or more zippers, tie strings, etc.) may be used in place of or in addition to the hook and loop fasteners described above.
In an exemplary embodiment, the cast cover 10 may include a core 60 which is adapted to fit within the pocket of the shell 20. As shown in FIG. 2, the core 60 may include a hole 62 which corresponds to the opening 50 in the shell 20. The core 60 may comprise an elastically-deformable foam, for example. In an exemplary embodiment, the core comprises 0.5 inch thick high-density closed-cell polyurethane foam. The core 60 may include other materials in addition to or in place of foam such as, but not limited to, other padding materials (such as, but not limited to, other foams and/or gels) and/or semi-rigid materials such as plastic sheet material. It is within the scope of the invention to utilize a core 60 which has a non-uniform thickness. In such an embodiment, the core may thicker at locations where additional padding is desired and may be thinner or absent at other locations. Further, it is within the scope of the invention to utilize a core comprised of a plurality of pieces.
In an exemplary embodiment, the core 60 may be removed from the shell 20 via the opening edge 40. The shell 20 may be cleaned and the same or another core 60 may be installed in the shell 20 prior to its next use. The user may select from a variety of cores 60 having different properties such as thickness, rigidity, elasticity, and the like based on the desired use.
The cast cover 10 may be constructed so as to satisfy the requirements set by an athletic organization for padding which must be worn over a cast by participants in an athletic event. For example, an athletic organization may require 0.5 inches of padding around a cast worn by a participant in an athletic event. An exemplary embodiment of the present invention may include sufficient padding to meet this requirement.
In some embodiments, the shell 20 and/or the core 60 may be constructed of materials which are soft, lightweight, durable, and/or washable. In addition, the materials used for the shell and/or the core 60 may be resistant to damage from water, dirt, sand, etc. Further, the shell 20 and/or the core 60 may be washable and reusable or may be disposable. The shell 20 may be constructed of a material which provides some padding and the shell 20 may include portions that are thicker or thinner than other portions. The shell 20 may be constructed of an elastically-deformable material such that, for example, the shell may stretch to conform to the object over which it is applied.
In an exemplary embodiment, the shell 20 may be constructed from latex-free, 80% polyester, and 20% spandex (elastane) 18 oz. (18 oz. per square yard) fabric. The fabric may be 4.5 mm (0.192 inches) thick.
The shell 20 and/or the core 60 may be provided in a variety of sizes and shapes. The various sizes and shapes may be adapted to fit users of various sizes and also may be adapted to be used to cover casts of various types, sizes, and shapes which may be used to immobilize various parts of the body.
