Golf club head

A golf club head that is capable of preserving the metallic acoustic signature of an entirely metallic golf club head all while utilizing a lightweight composite material is disclosed herein. More specifically, the golf club head in accordance with the present invention creates a frontal acoustic chamber in conjunction with a rear weight saving chamber via a panel member barrier is disclosed. The panel member may even be combined with an optimized thickness relationship at the transition region between the striking face portion and the panel member to further optimize the performance of the golf club head.

Multi-material golf club head

A multi-material golf club head having an improved performance is disclosed. More specifically, the present invention relates to a multi-material golf club head having a metallic frontal portion and a lightweight aft portion with an addition of an internal ribbon support member. The present invention may also further be comprised of a weighting mechanism that is accessible via an opening in the lightweight after portion but connects directly to the metallic frontal portion to mitigate any of the structural integrity issues associated with installing weights in a lightweight portion of a golf club head.

A golf club incorporating an interchangeable shaft system includes a shaft, a shaft sleeve, a club head. The shaft sleeve is coupled to an end of the shaft and is received in a hosel included in the club head. The shaft sleeve is removably coupled to the club head. Hosel and shaft sleeve alignment features provide discrete orientations between the shaft and club head.

Interchangeable shaft system

A golf club head comprising a body, a cavity having an open end and a terminal end, a weighted insert, the weighted insert comprising a heavy end and a lighter end, wherein the cavity comprises a head locking feature, wherein the weighted insert comprises an insert locking feature, wherein the insert locking feature is configured to lock the weighted insert in the cavity with less than 180 degrees of rotation, wherein the head locking feature comprises a slot, wherein the slot is arranged at an oblique angle relative to the longitudinal axis of the cavity, wherein the insert locking feature comprises a protrusion configured to engage the slot, the protrusion and the slot configured such that rotation of the insert locking feature relative to the head locking feature forces the insert locking feature to slide along the longitudinal axis of the cavity towards the terminal end of the cavity.

Metal wood club

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.

A golf club head with improved striking face performance is disclosed herein. More specifically, the present invention discloses a golf club head having a thickened central region surrounded by an internal and an external transition region; wherein the thickened central region has an inner perimeter that takes on a shape that substantially resembles the shape of an outer perimeter of the striking face of the golf club head.

Striking face of a golf club head

A more efficient triangular shape for metal wood clubs or driver clubs is disclosed. This triangular shape allows the clubs to have higher rotational moments of inertia in both the vertical and horizontal directions, and a lower center of gravity.
