Abstract: A remotely adjustable grip tip assembly for a walking aid, such as a crutch, cane, or walking stick that has a hollow tubular structure. The assembly includes a rod extending vertically within the hollow tubular structure, slots formed into the hollow tubular structure near its top and bottom ends, an adjustment screw or pin fitting into each slot, a spring near the bottom end of the hollow tubular structure, and a moveable gripper foot at the bottom end of the hollow tubular structure.

Abstract: An anchor for an elongated structural member comprising sidewalls rigidly affixed in a spaced apart and confronting relation to a generally planar base for defining a channel to receive and secure the structural member to the planar base. The sidewalls have diverging sidewall surfaces from apexes from which the spaced and parallel sidewall surfaces extend in opposite directions along the planar base and support at least one prong to secure the planar base by the parallel sidewall surfaces. The prong is operatively positioned by upon rotational movement of the diverging sidewall surfaces to adjacent opposite sides of such a structural member.
