Abstract
A prosthetic device (14) is provided having a proximal end portion (16) adapted to be secured to an amputee and a distal foot structure (18). The improvement comprises a pivoting ankle joint disposed between the proximal end portion (16) and the foot structure (18). This ankle joint includes a mated socket (22) and head (26) assembly interconnecting the proximal end portion (16) and the foot structure (18) for relative movement about a pivot axis between first and second positions. A spring element operates to resiliently bias the socket and head into the first pivot position. A load sensitive locking mechanism (24) operates, upon the existence of a triggering load which exceeds a predetermined threshold magnitude, to cause the socket (22) and head (24) assembly to lock at a selected locking position, thereby preventing relative pivotal movement. In the absence of the triggering load, relative pivotal movement of the socket (22) and head (24) assembly between the first and second positions is permitted.
Claims
1. In a prosthetic leg device adapted to be worn by a human amputee wherein said leg device has a proximal end portion adapted to be secured to the amputee and a distal foot structure, the improvement comprising a pivoting ankle joint disposed between said proximal end portion and said foot structure, said ankle joint including a matable socket and head assembly interconnecting said proximal end portion and said foot structure for relative pivotal movement about a pivot axis between first and second pivot positions, said socket and head assembly including a socket disposed on one of said proximal end portion and said foot structure and a head sized to be matably received by said socket and disposed on another of said proximal end portion and said foot structure and including a spring element associated with said socket and head assembly and operative to resiliently bias said socket and head into the first pivot position.
2. The improvement according to claim 1 including a socket housing disposed on said foot structure, said socket housing being sized and adapted to mount said socket and including a stiff yet resilient first material interposed between said socket and said socket housing.
3. The improvement according to claim 1 wherein said ankle joint includes a load-sensitive locking mechanism associated with said socket and said head assembly, said locking mechanism operative in response to a triggering compressive force between said socket and head in excess of a threshold magnitude to cause said socket and head assembly to lock at a selected locking position between the first and second pivot positions thereby to prevent relative pivotal movement of said socket and head and operative in an absence of a triggering compressive force to permit relative pivotal movement of said socket and head between the first and second positions.
4. The improvement according to claim 3 wherein said socket and head assembly includes a shaft secured to said proximal end portion and extending along a central axis to
