ABSTRACT:
An adjustably positioned handgrip assembly for an ambulatory aid includes an elongated rigid body having an axial cylindrical bore for receiving a cylindrical tube end of the ambulatory aid. The body has an oval portion of maximum size at one end tapering gradually to a plane of minimum oval cross section near the other end, then gradually becoming circular to terminate in a circular portion at the other end. A plug insert which fits into the tube end of the ambulatory aid has notches selectively engageable with lugs in the cylindrical bore of the body for securing the body in any one of a plurality of angular positions on the tube end of the ambulatory aid. An axial bore attaches the body of the handgrip assembly to the ambulatory aid.
