Crutch designed to assist person with disabled leg

摘要

The crutch is made from three tubes (1-3) of carbon steel or aluminium alloy, i.e. a main tube (1) which is bent over at the top to form a handle, a second tube (2) which can be slidably adjusted in the first, and a third tube (3), bent into a U-shape and fixed to the main tube by welding or a screw. The upper ends of the third tube are bent over and downwards to provide a support for the forearm. The open ends of the handle and upper tube are filled by stoppers, and the upper tube and handle are partially or completely covered with polyurethane foam.
