Patent ID: 8142381

Claim:
A foot brace device, comprising: A) a shoe assembly having a bottom wall with a first underside, a first upperside and a peripherally extending wall perpendicular to said bottom wall adapted to receive therein a user's foot cast, said shoe assembly having a front end and a rear end with two opposite ear portions extending from said peripherally extending wall away from said bottom wall, said ear portions being adjacent to said rear end; B) a sole assembly having substantially the same projected dimensions as said shoe assembly and further including a second upperside and a second underside, spring biased means for mounting said sole assembly to said first underside, said sole assembly having moving independent rear, middle, and front portions that are brought against said first underside when a user applies his or her weight during his or her entry gait, bearing weight and exit gait, proportionally to the weight applied thereby sequentially and gradually absorbing the application of said user's weight load; C) two opposite parallel and spaced apart extension flat bracing members, each defining a plane and each pivotally and adjustably mounted to each of said ear portions to move over said respective planes a predetermined angular range adapted to the characteristics of said foot cast; and D) strap means for securing said shoe assembly and extension bracing members to a user's foot cast and leg, and said spring biased means includes a plurality of upper tubular guide members perpendicularly and rigidly mounted to said first underside and each of said upper tubular guide members including a distal end surface and a centrally disposed slot starting at a predetermined distance from said end surface, and said spring biased means further including a corresponding plurality of lower tubular members perpendicularly and rigidly mounted to said second upperside and being receivable within said upper tubular guide members and each of said lower tubular members including a resilient guiding protrusion mounted exteriorly on said lower tubular members for cooperative cammingly insertion within said upper tubular guide members and for subsequent lodging said protrusion within said slots to correspondingly limit the telescopic travel of said upper tubular guide members and lower tubular members within a predetermined distance, wherein said spring biased means includes a corresponding plurality of spring members having first and second ends with a helical shape that receive therein said lower tubular members and said first end coacting with said second upperside and said second end coacting with said distal end surface to urge said sole assembly to separate from said shoe assembly.
