CA 2237340

A self-adjusting crutch having a floating and moveable central leg. A prepositionable height fastener cooperates with a coupling collar, both of which are disposed on the central leg to predetermine the amount of extension. A fastener and coupler cooperate, for the leg to be extended and retracted repeatedly the exact same distance. The floating moveable leg can be releasably retained within the arm piece.

Cette invention concerne une béquille télescopique à réglage automatique en longueur comportant une patte centrale flottante. Une butée de réglage en longueur prépositionnable coopère avec une collier d'accouplement, les deux étant disposés sur la patte centrale de la béquille et adaptés pour prérégler la longueur de la béquille. La butée et l'accouplement opèrent ensemble pour l'allongement et le raccourcissement d'une distance exactement identique d'une fois à l'autre. La patte mobile flottante peut être assujettie de façon amovible au montant de la béquille.
