Patent ID: 8678021

Claim:
A tip configured for removable attachment to a walking aid device comprising: a base member having an inner surface, an outer surface, and an outer rim between the inner surface and the outer surface, the outer rim defining a horizontal plane; a shaft projecting from the inner surface and being radially symmetric about a central axis, the shaft defining a bore operable to receive and retain the walking aid device, the bore having an open end opposite the inner surface; and a plurality of spaced apart ribs projecting from the inner surface, each of the plurality of spaced apart ribs extending radially from the outer rim to the shaft, each of the plurality of spaced apart ribs having a top edge away from the inner surface, and each of the top edges lying substantially in the horizontal plane; wherein the inner surface is concave facing toward the shaft; the outer surface is convex and substantially parallel to the inner surface, a curve segment defined by the intersection of the outer surface and a plane including the central axis being a continuous curve segment without an inflection point over the whole length of the curve segment; the base member, the shaft, and the plurality of spaced apart ribs are flexible; and the plurality of spaced apart ribs are configured to flex in response to a downward compressive force on the shaft.
