## Abstract

A hinged ankle brace including a foot pad member and an ankle cuff which are hingedly secured together by flexible joint members. The flexible joint members yieldably resist hinged movement between the foot pad member and the ankle cuff.

## Claims

### Claim 1

A hinged ankle brace, comprising:
a foot pad member having a medial side with an upper end portion and a lateral side with an upper end portion;
an ankle cuff having a medial side with a lower end portion and a lateral side with a lower end portion;
said lower end portion of said medial side of said ankle cuff having three spaced-apart connector openings formed therein, each of which are configured to receive a connector therein;
said lower end portion of said lateral side of said ankle cuff having three spaced-apart connector openings formed therein, each of which are configured to receive a connector therein;
said lower end portion of said medial side of said ankle cuff being positioned adjacent said upper end portion of said medial side of said foot pad member;
said lower end portion of said lateral side of said ankle cuff being positioned adjacent said upper end portion of said lateral side of said foot pad member;
a flexible one-piece medial joint member positioned between said lower end portion of said medial side of said ankle cuff and said upper end portion of said medial side of said foot pad member;
said flexible one-piece medial joint member having six spaced-apart connector openings formed therein, each of which are configured to receive a connector therein;
said flexible one-piece medial joint member being connected to said lower end portion of said medial side of said ankle cuff by three connectors extending through said three connector openings formed therein and through three of said six connector openings in said flexible medial joint member for yieldably resisting hinged movement therebetween;
a flexible one-piece lateral joint member positioned between said lower end portion of said lateral side of said ankle cuff and said upper end portion of said lateral side of said foot pad member;
said flexible one-piece lateral joint member having six spaced-apart connector openings formed therein, each of which are configured to receive a connector therein; and
said flexible one-piece lateral joint member being connected to said lower end portion of said lateral side of said ankle cuff by connectors extending through said three connector openings formed therein and through three of said connector openings in said flexible one-piece lateral joint member for yieldably resisting hinged movement therebetween, wherein each of said flexible one-piece medial joint member and said flexible one-piece lateral joint member has three elongated arms having outer ends and wherein a connector opening is formed in each of said elongated arms, wherein the flexible one-piece medial joint member and the flexible one-piece lateral joint member are configured to provide greater resistance to hinged movement of the foot pad member and the ankle cuff as the foot pad member and the ankle huff hingedly move to a greater degree with respect to one another, the three elongated arms of each of the flexible one-piece medial joint member and said flexible one-piece lateral joint member being configured to bend during hinged movement of the ankle cuff relative to the foot pad member and the bend of the three elongated arms creates greater resistance to hinged movement of the foot pad member and the ankle cuff.

### Claim 2 (depends on 1)

The hinged ankle brace of claim 1 wherein said connectors are bolts.

### Claim 3 (depends on 2)

The hinged ankle brace of claim 2 wherein a threaded nut is embedded in each of said six connector openings in said flexible one-piece medial joint member and said flexible one-piece lateral joint member for connection to said bolts.

### Claim 4 (depends on 1)

The hinged ankle brace of claim 1 wherein said connectors are rivets.

### Claim 5 (depends on 1)

The hinged ankle brace of claim 1 wherein said connectors are screws.

### Claim 6 (depends on 1)

The hinged ankle brace of claim 1 wherein said flexible one-piece medial joint member and said flexible one-piece lateral joint member are flat.
