ABSTRACT:
A reducible walking aid is disclosed that incorporates three bitubular sections in slidable engagement with one another in the preferred embodiment. The first and third sections are connected via a pair of elastic cables attached to slidable, bidirectional hinge elements anchored to the near ends of the first and third sections, with the cables running through the tubular sections of the second section. To reduce the size of the walking aid, one pulls in opposite directions on the first and second bitubular sections. Once the hinges are generally clear of the second section, the first section is folded over the second section in one direction. The third section is folded in the opposite direction in a similar fashion to accomplish the complete folding of the crutch. To restore the walking aid to its original operating size, one grasps the folded first and third sections and opens them until they are in generally axial alignment with the second section, at which time the first and third sections slide into the second to provide a rigid vertical support. Means are also provided for adjusting the height of the walking aid both below and above the hand grip. The hand grip is of novel design and is adjustable along an infinite number of positions on the second section.
