Abstract

A system for stabilizing the injured ankle of a user has an ankle brace with an upper calf member hingedly connected to a lower foot member, and a plurality of reinforced areas for strengthening and supporting a region around the talus bone. The reinforced areas are located above and below the hinge, or in the proximate vicinity of the ankle and talus bone. The hinge is located on an outwardly bowed cup-shaped portion of the ankle brace for comfortably receiving the mallseli of the user. The upper member includes a pair of arcuate elements slidable with respect to one another to adjust the opening formed thereby for various calf sizes. The lower member is designed to reduce stiffness in areas such as the front of the foot. Several straps are provided to securely couple the upper member and lower member to the user. Inner pads and tapered edges of the structural members reduce abrasion of the ankle brace against the user.

Claims

1. An ankle brace for use during physical activity, said ankle brace being adapted to be worn on a foot of a user and extend partway up the lower leg, said ankle brace comprising:

an upper member comprising plural arcuate submembers overlapping one another to provide an adjustable size opening for receiving the calf of the user;

a lower member adapted to receive the foot of the user;

a hinge connecting said upper member to said lower member to allow said members to flex with respect to one another, said hinge adapted to be positioned on said ankle brace adjacent the talus bone of the user; and

at least a single taloric control device on at least one of said members in the region of the hinge for strengthening and supporting the talus bone in its various articulations, said taloric control device comprising lateral reinforcement areas disposed directly adjacent the hinge, slightly above the hinge, and slightly below the hinge, whereby injury to the ankle is inhibited.

2. The ankle brace of claim 1, wherein said lower member comprises two lower submembers, each of said lower submembers having at least one taloric control device located thereon and opposite one another, said lower submembers adapted to extend on either lateral side of the user'"'"'s foot when said lower member receives said foot.

3. The ankle brace of claim 1, wherein the lower member comprises a pair of stabilizing members configured to be mounted on anterior and posterior sides of the hinge.

4. The ankle brace of claim 3, wherein said lower member comprises two lower submembers, said lower submembers adapted to extend on either lateral side of the user'"'"'s foot when said lower member receives said foot, wherein said stabilizing members comprise adjustable straps mounted on said lower member, said adjustable straps adapted to securely couple said lower submembers over said foot.

5. An ankle brace for use during physical activity comprising:

an upper member;

a lower member adapted to extend below the upper member, said upper and lower members configured to be securely mounted on a foot of a user and extend partway up the lower leg;

a hinge connecting said upper member to said lower member to allow said members to flex with respect to one another, whereby movement of the user is permitted, said hinge adapted to be positioned on said ankle brace adjacent the talus bone of the user; and

at least a single taloric control device on at least one of said members located in the region of the hinge for strengthening and supporting the talus bone in its various articulations, said taloric control device comprising lateral reinforcement areas disposed directly adjacent the hinge, slightly above the hinge, and slightly below the hinge, whereby the articulations of the talus bone are supported in their movements and injury to the ankle is inhibited.

6. An ankle brace for use during physical activity, comprising:

an upper member;

a lower member adapted to extend below the upper member, said upper and lower members configured to be securely mounted on a foot of a user and extend partway up the lower leg;

a hinge connecting said upper member to said lower member to allow said members to flex with respect to one another, whereby movement of the user is permitted, said hinge positioned on an ankle region of said ankle brace, said ankle region adapted to be positioned near the talus bone of the user; and

at least a single taloric control device on at least one of said members located in the region of the hinge for strengthening and supporting the talus bone in its various articulations;

said lower member comprising a pair of adjustable straps configured to be mounted on anterior and posterior regions of the ankle region of the ankle brace, said adjustable straps mounted on said lower member and adapted to securely mount said ankle region about the talus bone of the user, whereby injury to the talus bone is inhibited.

7. An ankle brace for use during physical activity, comprising:

an upper member;

a lower member;

a hinge connecting said upper member to said lower member to allow said members to flex with respect to one another; and

at least a single taloric control device on at least one of said members in the region of the hinge for strengthening and supporting the talus bone in its various articulations, said taloric control device comprising lateral reinforcement areas disposed directly adjacent the hinge, slightly above the hinge, and slightly below the hinge, whereby injury to the ankle is inhibited.
