ABSTRACT:
A crutch tip assembly (12) comprises a solid base (14) having substantially vertical side surfaces (18, 20, 54, 56) and outwardly, downwardly tapered front and rear surfaces (22, 24, 51a, 51b) with convex bottom surface (26, 52) forming an approximate arc elongated in a direction approximately parallel to the side surfaces. A laterally outwardly protruding lip (28, 50) is positioned adjacent the bottom surface near bottom edges of the side, front and rear surfaces on which a resilient boot (16, 70) having the shape of a rocker is mounted. The resilient boot defines a mounting cavity (36, 72) for snugly receiving the solid-base bottom surface and the lip for holding the boot on the solid base. An elongated, centered, arch-shaped groove (38, 74) extends along a bottom surface of the boot. The solid base is attached to a single support 33 at a lower end of a crutch frame 34 by means of a tongue (30, 68) and groove (32) joint and alternately an adhesive or other affixing means.
