Abstract
A first member of an artificial limb such as a tube socket has a generally rhombic flange formed with throughholes grouped into an anterior-posterior pair and a medial/lateral pair spaced at 90 degree intervals about the axis of socket. The lower face of the flange carries a ball formation of a ball and socket articulation. A second member in the form of ankle attachment plate has a concave seat that accepts the ball and threaded bores conforming to the through holes. The first and second members are held together by clamping screws received in the bores that fit onto washers having spherical lower faces that articulate on seats. The resulting alignment device is simple to manufacture and preserves angular position when an adjacent pair only of the clamping screws are removed. A similar alignment device having a cylindrical projection articulating in a cylindrical seat under the control of a single pair of clamping screws provides for heel height adjustment.
