  • Patent number: 9737770
    Abstract: A golf club head is provided with a body that has an address position with a zero degree bounce portion on the sole and a center sole position with a multi-relief surface of the sole having a negative bounce portion. The negative bounce portion may comprise a negative 0.5 to a negative 4.0 degree surface. In one embodiment, the multi-relief surface may comprise the negative bounce portion and a cutaway portion extending to the back of the sole, which may have a depth of about 0.05 to 0.5 inch from a regular sole surface. In another embodiment, the golf club head includes a weight system to adjust the center of gravity. In one embodiment, the weight system is a tube having a weight at one end that may be inserted into the golf club head to move the center of gravity at least forward and backward within 6 mm and up and down within 6 mm. Preferably, the tube is angled downward toward the face by at least 3 degrees.

  • Publication number: 20160067571
    Abstract: The invention generally relates to golf clubs with sound tuning features. In certain aspects, the invention provides a flanged rib structure configured to provide improved sound tuning characteristics for a golf club head, particularly a hollow-bodied golf club head. In one embodiment, the rib includes a web portion extending from an internal surface of the club head body and a flange portion coupled to a top surface of the web portion. The inclusion of the flange portion to the web portion increases the overall stiffness of the rib, thereby resulting in an increase in the natural vibration frequency of the club head so as to provide a more appealing sound and/or feel upon ball impact, thereby improving the overall sound characteristics of the club head.

  • Publication number: 20150045141
    Abstract: A metal wood golf club with a striking face portion made from more than one material is disclosed. More specifically, due to the unique construction of the striking face portion having multiple materials, the present invention utilizes diffusion bonding, liquid interface diffusion, or even super plastic forming techniques to achieve the desirable bond between the more than one material used to form the striking face. The striking face portion is formed by adding a chip insert made from a secondary material that is different from the remainder of the striking face portion substantially near a geometric center of the striking face portion; wherein the secondary material has a higher Young's modulus than the remainder of the striking face portion.
