  • Self aligning and quick coupling device for a prosthesis
    Patent number: 5326352
    Abstract: An apparatus for use in attaching a leg prosthesis. The purpose of this coupling device is to allow for the quick attachment or detachment of the prosthesis without removal of the bucket portion which is left connected to the wearer by suction or by a belt. The device is both self aligning and quick coupling. One plate has a plug and the other plate has a socket into which the plug fits. A threaded pin joins the two plates and forces the two plates, which are deliberately misaligned, together.
