Mechanical hip joint
First Claim
1. An articulating mechanical hip joint for attaching a robotic leg to a body member, comprising:
- a. a housing adapted for connection to said body member, said housing defining a first substantially spherically shaped socket therein, and a ball joint, received by said socket, for rotational movement thereof within said housing and socket about a predetermined first horizontal axis;
b. a bearing member, rigidly interconnecting said leg and ball, said bearing member defining a bearing surface confronting said housing and socket and constrained for rotational movement with said ball about said first horizontal axis; and
c. means, interconnecting said housing and said bearing member, for selectively rotating said leg and bearing member about a second horizontal axis, defined through said ball and transverse of said first horizontal axis, between predetermined first and second angular limits.

Abstract
A novel mechanical hip joint for attaching a robotic leg to a body member is described, which comprises, a housing adapted for connection to the body member, a spherical socket defined within the housing, a ball joint received by the socket for rotational movement about a first horizontal axis, a bearing member rigidly interconnecting the leg and the ball joint and presenting a bearing surface confronting the housing and socket, and a motor interconnecting the housing and bearing surface for selectively imparting rotary movement to the leg, about a second horizontal axis transverse of said first axis, between first and second angular limits.
