ABSTRACT:
Solid (e.g. wooden) and tubular crutches, are adapted for use with standard bolt-supported hand grips, are modified for use with a bolt supported hand grip, at a desired incline for user comfort. The angle of incline, from normal lateral placement, is predetermined and the parallel spaced apart sections of the crutch are correspondingly apertured along such angle, i.e. with through apertures, to permit placement of the hand grip supporting bolt at such angle. A series of correspondingly angled apertures on the crutch bows allows for height adjustment similar to the standard laterally aligned apertures. The angled aperturing may be in addition to the lateral apertures to permit both inclined and lateral hand grip placement as desired. Alternatively, the hand grip itself is formed with an integral incline, whereby, when it is normally laterally affixed to the laterally aligned apertures of standard crutches with a standard bolt and wing nut connection, an inclined grip is provided.
