Abstract
An improvement to a tubular height adjustable crutch of the type having a foot telescopically slidable within a carrier tube supported between the parallel lower ends of two crutch bows, where the crutch bow ends are right cylinders cut so as to form a right angle corner with the footpiece or carrier tube. A unitary end cap is fitted over the bow ends and the carrier tube for retaining these three members together and to provide an integral bushing for supporting the footpiece against wobbling within the carrier tube. The improvement consists of modifying the cap bottom to provide slanting edges or surfaces for deflecting staircase edges away from possible engagement with the corner defined between the bow ends and the carrier tube, thus preventing consequent injury to the crutch user.
