ABSTRACT:
A shift device for a prosthetic limb comprises: first and second plates having adjoining flat faces in sliding contact. Spaced parallel ribs on an outer face of each plate define a slideway. Guides in the slideways of the first and second plates enable the plates to move generally at right angles to one another. The guides include first and second guide bars slideably received in the respective slideways. One or more longitudinal slots in each slideway permit limited relative translational movement of the plates. Clamping screws pass through each slot of each of the first and second plates into the guide bar in the slideway of the other plate. The clamping screws are releasable to allow relative movement of the plates and on re-tightening immobilize the plates.
