Gel and air cushion ankle brace
First Claim
1. An ankle brace for use in connection with minor ankle injuries, such as Grade I or Grade II sprains, within a shoe, comprising:
- an outer flexible casing conforming to the shape of the ankle and rear portion of the foot and having front edges which are close to one another along the front of the ankle and instep of the user;
means for adjustably holding said front edges together;
first and second wide elastic straps extending from said casing to cross over one-another in a cruciate configuration with one end of each of said straps being secured to said casing on different sides thereof;
first and second lines secured to the other ends of said first and second elastic straps, said lines extending through first and second holes, respectively, in said casing, on opposite sides thereof;
means secured to the outer ends of said lines for coupling to the laces of a shoe;
left and right air bladders mounted within said casing, on the sides thereof, andgel pad means mounted within said casing and within and adjacent said air bladders for cushioning the ankle and distributing inwardly directed pressure;
whereby the ankle of the user may be limited in its motion as desired by (1) varying the tightness of said casing, (2) varying the pressure in said air bladders, and (3) varying the tension applied from the shoe laces through said lines to said wide elastic straps.

Abstract
An ankle brace designed to be worn under the shoe has a first bladder which is filled with the high viscosity gel resistant to rapid deformation to apply pressure to the ankle and conform to its shape to provide support to the ankle. A second bladder inflatable with air is juxtaposed the first bladder to provide a uniform compressive force upon the bladder filled with the gel. A canvas ankle brace holds a pair of air and gel bladders along each of its sidewalls and is wrapped about the lower extremity and snugly fit thereto. Once the brace is in position, air is introduced into the second bladder to press the first bladder against the ankle and to conform to the shape thereof. Broad elastic straps may be secured to the lower rear of the brace to extend over the front of the ankle and the instep in a cruciate configuration. The outer ends of the straps are secured to lines which extend through openings in the outer casing of the brace, and D-rings secured to the ends of the lines permit the tensioning of the elastic straps by threading shoe laces through the rings and tightening the laces.
