Abstract
A compacting, adjustable walking aid comprising a shaft (20) made up of three rigid tubular members (22, 23, 24) arranged in telescopic fashion adjustably connected to one another by spring-loaded push button release pins (25) in cooperation with apertures in the tubes.

A readily removable crutch handle (32), secured by a hand operated release assembly (32C), extends perpendicularly from a designated portion of the upper tubular member (22). This invention may be readily compacted telescopically to approximately one third of its extended length. By removing the upper shaft tube (22), and capping the middle shaft tube (23) with the appropriate attachment, this invention may be readily converted from a full-sized crutch to a forearm crutch (46), or a cane (48). Shock absorbing end tip (34) may be replaced with a quad tip attachment (50) transforming the cane to a quad cane.
