Abstract: An improved artificial leg has a ball and socket ankle joint (3) connecting a foot (2) to a shin member (1). The ankle joint comprises a two-part socket (5A, 5B) enclosing a part-spherical ball member (4) with an elastic sleeve (6) sandwiched between the socket and the ball member (4) to allow resilient flexion of the foot (2) relative to the shin member (1). In order to provide relatively more resistance to dorsi-flexion than to plantar-flexion, an elastic buffer in the form of a ring (11) is disposed around a coupling shank portion (4A) of the ball member (4) to engage a downwardly extending anterior skirt portion (12) of the socket. In the preferred embodiment of the invention the skirt portion (12) also extends around each side of the ring (11) to provide resistance to medial and lateral flexion.

Abstract: An artificial leg has a ball and socket ankle joint, the socket of which has upper and lower portions. They are connected together and clamped over the ball by a turnbuckle ring. This provides an adjustable shin and foot connection which permits use of a rubber-encased ball of sufficient size, without taking up too much shape within the ankle region. Also disclosed is a movable patella member and a vertically jointed two part foam covering.
