Abstract

Athletic footwear including a pair of resilient ankle braces which are supported to the sole, inner lining and a separately bound calf support collar of an athletic shoe. The braces are configured of a deformable polymer and include apertures shaped to accommodate protruding ankle bones. Curved lower ends of each brace mount to the heel region of the sole. Formed pockets or restraint means support the braces to the shoe liner. A separately mounted, cushioned collar restrains the upper brace end to the calf. In other constructions, one or more cushioned brace portions may be supported between the shoe and foot. In still another construction, a two-piece, hinged polymer brace is considered.

Claims

1. Ankle support apparatus comprising:

(a) a shoe having an outer shell and a liner means secured to an inner surface of said shell for cushioning a foot surrounded by said shell and including means for defining a plurality of open-ended channelways;

(b) first and second polymer braces, wherein each brace includes a minor arm portion which mounts adjacent a heel region of said shoe, a major arm portion which extends from said minor arm portion, and means for accomodating an ankle protrusion, and wherein a portion each of said first and second braces projects from one of said channelways;

(c) means for fastening said first and second braces to said shoe; and

(d) collar means for restraining said first and second braces to the calf and including a covered cushion having means for supporting the projecting portions of said first and second braces to said collar means, and fastener means for binding said collar means and the projecting portions of said first and second braces to the calf.

2. Apparatus as set forth in claim 1 wherein said shoe further comprises a court shoe and the minor arm portion of each of said first and second braces is mounted in overlying relation to the other.

3. Apparatus as set forth in claim 2 wherein said shoe includes a sole pad having a recess and wherein said overlapped braces mount within said recess.

4. Apparatus as set forth in claim 1 wherein the brace fastening means comprises a plurality of screw fasteners which mount through a plurality of apertures in the minor arms of said first and second braces.

5. Apparatus as set forth in claim 4 wherein said apertures are countersunk to receive a head portion of said screw fasteners.

6. Apparatus as set forth in claim 1 wherein said shoe further comprises a cleat portion and a distal end of the minor arm of each of said first and second braces abut one another and are fastened to said shoe with a plurality of fasteners which cooperate with said cleat portion and which contains a mating fastener portion.

7. Apparatus as set forth in claim 1 wherein said collar means includes first and second channelways for containing the projecting portions of each of the first and second braces.

8. Apparatus as set forth in claim 7 wherein each of the channelways of said shoe and said collar are comprised of an abrasion resistant and slippery material relative to said first and second braces.

9. Apparatus as set forth in claim 1 wherein the ankle protrusion means comprises respective first and second apertures in said first and second braces.

10. Apparatus as set forth in claim 9 wherein each of said first and second braces is coated with an elastomer.

11. Apparatus as set forth in claim 1 wherein each of said first and second braces are formed from a fiber containing resin and exhibit a width in the range of 11/2 to 4 inches and a heighth between 6 and 12 inches.

12. Apparatus as set forth in claim 11 wherein selected regions of said fibers are wound in different predetermined axial orientations such that preferential flexion characteristics are imparted to each of said first and second braces.

13. Apparatus as set forth in claim 11 wherein each of the first and second braces include a plurality of apertures whereby the axial flexion properties of the first and second braces are tailored.

14. Apparatus as set forth in claim 1 including a stocking having a pair of tubular channelways wherein said major ends of said first and second braces are restrained.

15. Apparatus as set forth in claim 1 including strap means for restraining each of said first and second braces to the liner means of said shoe.

16. Apparatus as set forth in claim 1 wherein said liner means includes respective first and second flap portions at ones of said channelways and means for securing said first and second flap portions to the outer shell upon admitting said first and second braces to the channelways.

17. Ankle support apparatus comprising:

(a) a shoe having an outer shell and liner means secured to said an inner surface of said shell and including a plurality of openings for cushioning a foot surrounded by said shell;

(b) polymer brace means formed to include a heel portion which mounts adjacent a heel region of said shoe, first and second arms which extend from said heel portion, and means for receiving an ankle protrusion, and wherein portions of each of said first and second arms are cushioned by said liner means and project from one of said openings;

(c) means for retaining said heel portion to said shoe; and

(d) collar means including a cushion portion for supporting ends of said first and second arms which project from said openings and fastener means for binding said collar means and said brace means to the calf.

18. Apparatus as set forth in claim 17 wherein the protrusion receiving means comprises respective first and second openings in said first and second arms.

19. Ankle support apparatus comprising:

(a) a shoe having an outer shell and liner means secured to an inner surface of said shell for cushioning a foot surrounded by said shell and for defining a plurality of open-ended channelways;

(b) polymer brace means including a heel portion which mounts adjacent a heel region of the shoe, first and second arms which extend from said heel portion, and means for receiving an ankle protrusion, and wherein a portion of each of said first and second arms project from one of said channelways; and

(c) collar means for restraining said first and second arms to the calf and including a covered cushion portion having means for supporting said first and second arms to said collar means, and fastener means for binding said collar means and said first and second arms to the calf.
