Abstract: A brace for a walker has a body and two mounting clamps. The body has two ends and an internal cavity a through hole. The internal cavity is defined longitudinally in the body. The mounting clamps are cylindrical, are formed respectively on and protrude longitudinally respectively from the ends of the body, are mounted respectively around the legs, and each mounting bracket has a longitudinal mounting slot, an inner surface, multiple mounting posts and multiple mounting recesses. The longitudinal mounting slot is formed diametrically opposite to the end of the body. The mounting posts are formed on the inner surface of the mounting bracket. The mounting recesses are formed in the inner surface of the mounting bracket.

Abstract: A supporting strut for a wheelchair has a longitudinal shaft and a cross-shaft. The cross-shaft extends perpendicularly from the longitudinal shaft and has a mounting bracket, two proximal brackets, two distal brackets, a medial pivot hole and a brace pivot hole. The mounting bracket is U-shaped, is formed on and extends longitudinally from the distal end of the cross-shaft. The proximal brackets are mounted opposite to each other on the cross-shaft near the proximal end and are connected to the longitudinal shaft. The distal brackets are mounted opposite to each other on the cross-shaft near the distal end and are connected to the mounting bracket. The medial pivot hole is formed through the cross-shaft between the proximal and distal ends parallel to the longitudinal shaft. The brace pivot hole is formed through the cross-shaft between the medial pivot hole and the proximal end parallel to the longitudinal shaft.
