IMPROVED HEIGHT ADJUSTABLE CRUTCH ABSTRACT OF THE INVENTION "A height adjustable crutch having a bow comprised of a pair of hollow tubular vertical members which are angled downwardly toward each other with their lower extremities aligned in spaced-apart parallel relationship in their hollow tubular condition. A hollow tubular carrier is disposed between and in abutment with these tubular extremities and the three members are secured, as by a bolt through them in the upper area where they are in abutment, and by an integral encircling element at their lower extremities, encircling element being pinned at externally diametri- cally opposite points of abutment of such element with the extremities of the tubular members. The tubular carrier is orificed at selective intervals and receives an orificed tele- scoping foot member provided with at least one radially outwardly spring biased detent. This detent serves to lock the foot member in any disposition relative to the carrier when the detent is passed through any registering orifices of the carrier and foot member. The disposition of the foot member relative to this carrier may be changed by pressing the detent radially inwardly to where the foot member may then be slid upwardly or downwardly in relation to the carrier for redisposition and locking by the detent."
