<p>A forearm crutch with a telescopic leg that includes a shoe assembly at the distal end with convex surfaces for the forward and rear portions to maximize contact area upon making contact with a supporting horizontal surface and as the load transmission ends. The other end of the leg is rigidly mounted to a housing that receives a pivotally mounted handle assembly with a locking mechanism for settling the former at a predetermined angular disposition over a given angular range. An adjustable forearm support assembly is mounted to the housing, opposite to where the leg is mounted. The crutch includes battery operated light and horn circuits that can be readily actuated by a user.</p> |
