  • Patent number: 4806040
    Abstract: A ball and socket joint which allows the precise positioning of the line of contact between the ball and the socket utilizing a spherically curved socket and an offset radius ball. The significant manufacturing difficulties associated with the shaping of an offset radius socket is avoided by the use of the spherical socket and offset radius ball. Furthermore, the ball and socket configuration enables use of ceramic materials to produce the socket and/or ball components which, in turn, results in a dramatic increase of the life of the ball and socket joint.
