Abstract

An ankle bandage (1) for supporting an ankle and foot while allowing a relatively unimpeded walk. The ankle bandage has a generally sock-shaped main body enclosing the ankle and instep region of a user. The main body may be opened at a front closure and is made from a flexible, resilient, heat insulating material. A pocket (8,9,10) for containing a stabilizing support body (11) is defined by a separate material sewn on the inside of main body along seams 6 and 7. The supporting body (11) comprises two rail portions (18) extending from a point above the ankle area of the user on each side of the leg, a joining portion (19) coupling the upper ends of the rail portions and a heel support formed by distal tapering portions of the lower ends (20) of the rail portions (18). During use, the tapering portions do not overlap and the heel support is located below the instep area and against the outside of the foot. The heel support has a narrow width compared to the upper ends of the rail portions (18) which allows a comfortable and normal pivoting ankle motion during walking while maintaining support.

Claims

1. An ankle bandage comprising:

a main body, sized to receive a user'"'"'s foot, having an upper periphery sized to surround a user'"'"'s leg and an instep region sized to extend beneath the user'"'"'s foot;

the instep region comprising a central portion situated beneath the user'"'"'s foot;

said main body having an inside surface, said inside surface comprising a medial side surface, a lateral side surface, a posterior side surface and an anterior side surface;

a one-piece, stabilizing support body comprising medial and lateral rails, having upper and lower ends, and a joining portion coupling the upper ends;

said medial and lateral rails lying adjacent the medial and lateral side surfaces with said lower ends positioned at said central portion of said instep region; and

said upper and lower ends of said medial and lateral rails having widths, said widths of said lower ends being substantially less than said widths of said upper ends so as to allow a relatively unimpeded walking motion while avoiding abrasive injury to the foot.

2. The ankle bandage according to claim 1, wherein the main body is made from a flexible, resilient, heat insulating material.

3. The ankle bandage according to claim 2, wherein the heat insulating material is neoprene.

4. The ankle bandage according to claim 1, wherein the main body further comprises a front closure, which may be opened to facilitate adjusting the ankle bandage onto the user'"'"'s leg and foot.

5. The ankle bandage according to claim 1, wherein the main body has an opening sized to receive a user'"'"'s heel.

6. The ankle bandage according to claim 1, wherein a pocket is defined between the inside surface of the main body along the medial side surface, the lateral side surface and the posterior side surface and an inside material layer.

7. The ankle bandage according to claim 6, wherein the inside material layer is a flexible, resilient, heat insulating material.

8. The ankle bandage according to claim 1, wherein the stabilizing support body is perforated to allow air and moisture to pass through from the user'"'"'s leg and foot to an outside surface of the main body.

9. The ankle bandage according to claim 1, wherein the stabilizing support body is an initially flat, sheet of material, so that the stabilizing support body can be custom molded to a user'"'"'s leg and foot.

10. The ankle bandage according to claim 1, wherein the stabilizing support body is made from a material which can absorb microwaves to achieve a formable plastic state.

11. The ankle bandage according to claim 10, wherein the material for the stabilizing support body is a thermoplastic which is heat formable at a temperature above the body temperature and cools to a rigid, non-plastic state.

12. The ankle bandage according to claim 1, wherein the joining portion is positioned adjacent to the posterior side surface of the main body.

13. The ankle bandage according to claim 1, wherein the upper widths of the rails are sized to enclose a user'"'"'s ankle.

14. The ankle bandage according to claim 1, wherein distal tapering portions of the lower ends of the medial and lateral rails are bent inwards toward the instep region to form a heel support.

15. The ankle bandage according to claim 14, wherein the distal tapering portions are positioned adjacent to each other and do not overlap in the instep region.

16. The ankle bandage according to claim 1, wherein a stabilizing band is helically wrapped around the main body and instep region to provide additional support and adjustability.

17. An ankle bandage comprising:

a main body, sized to receive a user'"'"'s foot, having an upper periphery sized to surround a user'"'"'s leg and an instep region sized to extend beneath the user'"'"'s foot;

the instep region comprising a central portion situated beneath the user'"'"'s foot;

said main body having an inside surface, said inside surface comprising a medial side surface, a lateral side surface, a posterior side surface and an anterior side surface;

said main body being made from a flexible, resilient, heat insulating material;

a one-piece, stabilizing support body comprising medial and lateral rails, having upper and lower ends, and a joining portion coupling the upper ends;

said support body being made from a flat sheet of material which is heat formable at a temperature above the body temperature and rigid when cooled;

said medial and lateral rails lying adjacent the medial and lateral side surfaces with said lower ends positioned at said central portion of said instep region; and

said upper and lower ends of said medial and lateral rails having widths, said widths of said lower ends being substantially less than said widths of said upper ends so as to allow a relatively unimpeded walking motion while avoiding abrasive injury to the foot.

18. An ankle bandage comprising:

a main body, sized to receive a user'"'"'s foot, having an upper periphery sized to surround a user'"'"'s leg and an instep region sized to extend beneath the user'"'"'s foot;

the instep region comprising a central portion situated beneath the user'"'"'s foot;

said main body having an inside surface, said inside surface comprising a medial side surface, a lateral side surface, a posterior side surface and an anterior side surface;

a one-piece, stabilizing support body comprising medial and lateral rails, having upper and lower ends, and a joining portion coupling said me upper ends;

said medial and lateral rails lying adjacent the medial and lateral side surfaces with said lower ends positioned such that the lower ends do not overlap to form a heel support at said central portion of said instep region; and

said upper and lower ends of said medial and lateral rails having widths, said widths of said lower ends being substantially less than said widths of said upper ends so as to allow a relatively unimpeded walking motion while avoiding abrasive injury to the foot.
