Abstract
A golf club shaft grip having a polyurethane layer bonded to a felt layer with the thickness of the polyurethane layer to the felt layer being a minimum of about 0.18. The bonded-together layers are configured as a strip which is spirally wrapped about the shaft. A cap is then telescopically applied over the upper end of the shaft to prevent unraveling of the strip from the shaft. Alternatively, a split sleeve may be applied to the shaft to receive the strip.
Claims8
The combination of a grip and a tapered hollow golf club shaft having an upper grip-receiving portion, said combination comprising:
- a strip consisting of an open-pored felt layer having a generally flat inner surface and a closed pore polyurethane layer having its inner surface bonded to the outer surface of the felt layer, with the pores of such polyurethane layer extending generally normal to the longitudinal axis of the strip, and with the felt 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 the shaft;
- the strip being spirally wrapped about the grip-receiving portion of the shaft, with the upper end of the strip being flush with the upper end of the shaft;
- a cap formed with a slotted inner skin tightly telescopically received by the interior upper end of the shaft, an outer skirt that tapers at the same angle as the shaft and depends downwardly over the upper portion of the strip, with the outer skirt extending over and engaging the upper extremity of the strip to restrain the upper end of the strip from unraveling from the shaft;
- and
- a ferrule interposed between the lower end of the strip and the shaft, with the cap and the ferrule preventing movement of the abutting side edges of the strip along the shaft and also precluding unwrapping of the lower portion of the strip relative to the shaft.
