Spiral protrusion type handle grip

The combination of a handle of an impact imparting device the handle having a butt end, and a resilient grip, such combination comprising:

• a strip which is spirally wrapped about said handle, the strip consisting of an open-pored felt layer having a generally flat inner surface abutting the handle and a smooth 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, the thickness ratio of the polyurethane layer to the thickness of the textile layer being equal to or larger than approximately 0.18, and with 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;
• stitching extending from the underside of the felt layer over the outer surface of the polyurethane layer to bunch up the portion of the strip between such stitching to define a slip-inhibiting protrusion;
• an adhesive material applied over the inner surface of the felt layer;
• the strip being spirally wrapped about the handle with the side edges in adjoining relationship and the protrusion defining a spiral profile along the length of the strip;
• and
• the starting end of the strip being formed with outwardly and downwardly slanted leading and trailing areas on opposite sides of such starting edge, the rear portion of the leading area overlapping the trailing area to provide a smooth configuration of the strip on the butt end of the handle.

A slip-on golf club shaft handle grip, comprising:

• a strip consisting of an open-pored felt layer having an inner surface and an outer surface, and 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 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 the shaft;
• stitching extending from the underside of the felt layer over the outer surface of the polyurethane layer to bunch up the portion of the strip between such stitching to define a slip-inhibiting protrusion;
• a resilient sleeve, with the upper end of the sleeve being formed with a cap and the lower end of the sleeve being formed with a guide cylinder;
• and
• the strip being spirally wrapped about the sleeve between the bottom of the cap and the top of the guide cylinder with the protrusion defining a spiral profile along the length of the sleeve.

In the combination of a golf club shaft handle, a tapered resilient sleeve for said handle, such sleeve being formed at its upper end with a cap below which is formed a recess:

• a strip which is spirally wrapped about said handle, the strip consisting of an open-pored felt layer having a generally flat inner surface abutting the handle and a smooth closed pore polyurethane layer having its inner surface bonded to the outer surface of the felt layer, with the pore of such polyurethane layer extending generally normal to the longitudinal axis of the strip, the thickness ratio of the polyurethane layer to the thickness of the textile layer being equal to or larger than approximately 0.18, and with the textile layer providing strength for the polyurethane layer while the polyurethane layer both absorbs shocks and provides tackiness os as to inhibit slippage of a user's hand relative to said handle;
• stitching extending from the underside of the felt layer over the outer surface of the polyurethane layer to bunch up the portion of the strip between such stitching to define a slip-inhibiting protrusion;
• the strip being spirally wrapped about the sleeve between the bottom of the cap and the lower portion of the sleeve with the protrusion defining a spiral profile along the length of the grip;
• and
• the butt end of the strip being formed with a tongue that fits snugly within said recess when the strip is wrapped about the sleeve to provide a smooth configuration of the strip relative to the sleeve.

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

• a strip which is spirally wrapped about said handle, the strip consisting of an open-pored felt layer having a generally flat inner surface abutting the handle and a smooth 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, the thickness ratio of the polyurethane layer to the thickness of the textile layer being equal to or larger than approximately 0.18, and with 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;
• a slip-inhibiting protrusion formed on the strip along the length thereof;
• heat-compressed recessed reinforcing side edges formed along the length of the polyurethane layer;
• an adhesive material applied over the inner surface of the strip;
• and
• the strip being spirally wrapped about the handle with the side edges in adjoining relationship and the protrusion defining a spiral profile along the length of the grip.
