    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.
