Abstract

A shock absorbing grip for the handle of a tennis racquet or the like having polyurethane layer bonded to a felt layer where the ratio of the thickness of the polyurethane layer to the felt layer is equal to or larger than about 0.18. The polyurethane layer is formed with a plurality of dimples, each of which merge into a perforation that extends through the felt layer to permit breathing of air through the grip as it is grasped by a tennis player.

Claims

1. The combination of a handle for an impact imparting device, and a grip to be applied over such handle to conform to the external configuration of such handle, said grip comprising:

an open-pored textile layer having an inner surface adhered to and abutting said handle and a smooth closed pore polyurethane layer having its inner surface bonded to the outer surface of the textile layer remote from said handle, with the pores of such polyurethane layer extending generally normal to the longitudinal axis of said handle, the thickness ratio of the transverse central region of the polyurethane layer/textile layer being equal to or larger than approximately 0.18, the textile layer providing strength for the polyurethane layer while the polyurethane layer both absorbs shocks and provides tackiness so as to inhibit slippage of a user'"'"'s hand relative to said handle, and with the polyurethane layer being formed with a plurality of inwardly extending dimples, the lower end of each of which merge into a perforation that extends inwardly through said felt layer, air being forced through said dimples and perforations when the grip is grasped by a user with his palm and fingers covering some of the dimples.

2. The combination as set forth in claim 1 wherein the diameter of each dimple at its intersection with the outer surface is about 1/8", and the diameter of each perforation is about 1/32".

3. The combination as set forth in claim 1 wherein the thickness ratio of the transverse central region of the polyurethane layer is about equal to or thicker than the thickness of the textile layer.

4. The combination as set forth in claim 1 wherein the grip is in the form of a strip which is spirally wrapped about the handle.

5. The combination as set forth in claim 4 wherein the thickness of the textile layer tapers from a transverse central region towards the transverse sides to facilitate wrapping of the strip about said handle.
