Abstract
Abstract A cover for the butt end of the handle of a tennis racket is fabricated of a silicone polymer as a monolithic cup-like structure having a downwardly convex bottom portion of circular perimeter and a sidewall portion of upwardly convergent conic contour emergent from said perimeter. The sidewall portion tapers to form a very thin lip which securely grips the handle of the racket without presenting to the user's hand a perceptible feeling of structure.

Claim 1
Independent Claim

A cover for the butt extremity of a handle comprising a cup-shaped monolithic structure fabricated of a silicone polymer having a Shore A hardness between 40 and 50 and an elongation to break between 100% and 250%, said cover having a downwardly convex bottom portion of circular perimeter and a sidewall portion upwardly directed from said perimeter and terminating in a circular upper extremity representing the opening of said cover, said sidewall portion contoured as an upwardly convergent conical section bounded by interior and exterior surfaces which are upwardly convergent in a manner causing the thickness of said sidewall portion to diminish progressively with distance from said bottom portion, producing at said upper extremity an extremely thin lip adapted to snugly embrace said handle without presenting a perceptible feeling of structure, said bottom portion being defined by an upper surface and a lower surface having a series of upraised annular ridges.
