  • Patent number: 7264759
    Abstract: A grip for a sporting implement is formed of two rubber materials having different durometer rating and formed in a compression molded process. An underlisting is injection molded from one relatively hard rubber material providing desired torsional resistance and then an outer rubber layer is compression molded to the underlisting with the outer layer being having a durometer rating for providing desired tactile characteristics to the grip.
    Type: Grant

  • Publication number: 20040043827
    Abstract: A golf club grip is composed of an elastomeric material formed into a tubular form adapted to be received on the butt end of a golf club shaft with the grip having an upper semi-cylindrical portion of rubber material with cork particles disbursed therein and with a lower semi-cylindrical portion of the grip having the tip end of the same material as the upper semi-cylindrical portion of the grip and with the butt end of the lower semi-cylindrical portion having exposed cord for enhanced friction between the grip and a user's hands. A compression molding process is described for forming the grip from component strips and pieces of an elastomeric material.
