Abstract
A conventional tubular aluminum crutch which is modified to be conveniently folded 180.degree. into a compact size and stored when not in use. This crutch is cut in half and by using load-bearing double-male ended couplers which are friction fitted into the lower section struts for slidably engaging the upper section struts. Two cables are secured below the coupler by roll pins in each support tube of the lower section. These cables are then inter-connected to bungee cord within the upper section struts, and the opposite end of the bungee cords are secured by roll pins inside the support tubes of the upper section struts. When used, an individual simply unfolds the crutch, thereby allowing the bungee cord to contract and slidably engage the couplers of the lower section within the open ends of the upper section.
