Abstract: A knee/thigh pad holder assembly has adapter hardware for mounting adjustably to a wide variety of ambulatory aids such as walkers, canes, and crutches. The adapter hardware in one embodiment includes a bracket bolted to a knee/thigh pad holder with a holding rod clamped between the bracket and the knee/thigh pad holder. Adjustable clamps with clamping screws are employed to mount the knee/thigh pad holder via the holding rod across two parallel frame members of a walker. In another embodiment, a shorter tube is used in place of the holding rod, and rod clamps are pivotally attached to the short tube, such that the assembly may be adjustably mounted to a single upright member, providing thereby adjustable mounting to such as canes and crutches.
