发明名称 ADJUSTABLE ORTHOPEDIC CRUTCH
摘要 ADJUSTABLE ORTHOPEDIC CRUTCH An adjustable crutch has two vertical supports with an upper arm rest and a third, vertically adjustable lower support. The lower support fixes the overall height of the crutch. The independently moved hand grip is easily adjustable to provide proper spacing between the crutch's hand grip and arm rest based on the user's arm length. This construction requires only a two-step adjustment process which may be accomplished individually by the user.
