20150306474 | GOLF CLUB WITH ADJUSTABLE WEIGHT ASSEMBLY - The invention generally relates to golf clubs with adjustable mass properties. In certain aspects, the invention provides methods and mechanisms for adjusting a club head center of gravity and/or moment of inertia by way of an adjustable weight assembly positionable along the sole of the club head body. When in a first position, the weight assembly provides a lower center of gravity so as to increase launch angle and reduce spin rate, resulting in greater overall distance of ball flight. When in a second position, the weight assembly provides a greater mass moment of inertia, which effectively enlarges the sweet spot and produces a more forgiving club for off-center hits. | 10-29-2015 |

These inserts may have attachment surfaces that are relatively angled such that the inserts are subjected to compressive forces rather than shear forces upon impact with a golf ball during a golf swing. | 03-03-2011 |
20110034273 | CAVITY BACK GOLF CLUB HEAD - A golf club head having a cavity back design with a cavity therein for placement of lightweight dual-durometer silicone. The club head is prepared by brushing an adhesive onto the interior wall, but omitting a pre-selected area of the wall to allow silicone to shrink away at the omitted area to allow for control of the shrinkage. A first shot of 80 Shore A silicone is placed into the cavity and disposed against the interior wall. Next, a softer 50 Shore A silicone is juxtaposed against the first shot of silicone and it is pressed using a hot mold finishing tool wherein a substantial portion of the cavity is filled. A polycarbonate insert is attached to an outer surface of the second silicone to provide a zero gap appearance. A tan delta ratio of the first silicone to the second silicone is greater than 1.6. A storage modulus of the first silicone is at least three times greater than the second silicone. And, a loss modulus of the first silicone is at least ten times the second silicone. | 02-10-2011 |
20110034272 | GOLF CLUB HEAD WITH LOCALIZED GROOVES AND REINFORCEMENT - The present invention relates to a golf club head provided with a shell defining an inner cavity and having a face and a body. The face has a first or reinforcement portion with a first thickness and a second or remaining portion with a second thickness less than the first thickness. The reinforcement portion is located at the center of the face. In one embodiment, the exterior surface of the face defines at least one groove spaced from the center of the face. | 02-10-2011 |
20100261540 | MULTI-MATERIAL GOLF CLUB HEAD - A golf club head formed of multiple materials is disclosed. Those portions of the club head that are subject to high stresses during normal use of the golf club head are formed of a metallic material. Most of the material beyond what is required to maintain structural integrity, however, is removed and replaced with a lightweight material. This freed-up mass that can be redistributed to other, more beneficial locations of the club head. The lightweight material also damps vibrations generated during use of the golf club. This vibration damper may be retained in a state of compression to enhance the vibration damping. One or more weight members may be included to obtain desired center of gravity position, moments of inertia, and other club head attributes. An insert formed of multiple materials and having regions of varying thickness may also be included on a rear surface of the club head. | 10-14-2010 |
