Abstract: Disclosed golf club heads include a weight channel positioned in the sole and defining a path along the sole. A weight member positioned in the weight channel can be adjusted to any of a range of selectable positions to adjust mass properties of the golf club head. A fastener secures the weight member in any of the selectable positions. The weight member can have ribbed weight projections on an inward-facing surface that engage ribbed projections of the weight channel when the fastener is tightened. A compressible spacer positioned between the weight member and the body inside the weight channel can expand to create a gap between the ribbed weight projections of the weight member and the ribbed projections of the weight channel when the fastener is loosened.

Abstract: A golf club head having a nonmetallic crown bonded to a frame in close proximity to the face.

Abstract: Described are embodiments of golf club heads having an internal cavity and features that cause the golf club head to have an improved acoustic performance when striking a golf ball. Some embodiments include one or more weight tracks and/or weight ports formed in the sole for receiving adjustable weights. The golf club heads can include one or more internal ribs, thickened wall regions, and/or posts positioned within the cavity that increase the rigidity of the club head and improve the acoustic performance of the club head when striking a ball.

Abstract: Golf club heads include at least one weight port situated to retain weights and positioned above an approximate club face geometric center with the club in a standard address position. One, two, or more weight ports can be located above the club face center in a club crown or other portion of a club body. Club head vertical center of gravity can be selected to compensate dynamic loft associated with locating the club head center of gravity well behind the club face. Three-dimensional adjustment of club head center of gravity is possible.

Abstract: Disclosed golf club heads include a body defining an interior cavity, a face, a sole, a crown, and a hosel. Certain embodiments include a weight channel positioned in the sole and defining a path along the sole. Some embodiments include a weight member positioned in the weight channel that is configured to be adjusted to any of a range of selectable positions to adjust mass properties of the golf club head. A fastener may be configured to secure the weight member in any of the selectable positions, while the fastener itself, regardless of where the weight member is positioned along the path, may be secured to the body at a fixed location that is independent of the position of the weight member along the path.

Abstract: Golf club heads are provided for selectively increasing or optimizing the coefficient of restitution (COR) at likely impact locations on the striking face of the golf club heads, while simultaneously maintaining characteristic time (CT) below a threshold value in those likely impact locations. By analyzing historical impact locations of a large cross-section of golfers, golf club head COR values can be increased or optimized in preferential locations on the striking face, such as using weighting factors for a predefined set of locations on the striking face. Therefore, instead of increasing COR uniformly across the face and/or increasing COR at impact locations on the face where golfers are unlikely to strike the golf ball, the sweet spot of the golf club head can be increased at the impact locations where golfers typically strike the golf ball.

A fastener has a shaft portion extending through a passage and a head portion located in the recessed port. Selectively attaching the sleeve adjusts at least one of a loft angle and a lie angle of the club head.

The body having a channel located on the sole and extending generally from a heel end of the body to a toe end of the body. A weight member movably positioned within the channel such that a position of the weight member within the channel is able to be adjusted, thereby adjusting a location of a center of gravity of the body. Additionally, adjustment of the weight member provides a maximum x-axis adjustment range of the position of the center of gravity (Max ?CGx) that is greater than 2 mm and a maximum z-axis adjustment range of the center of gravity (Max ?CGz) that is less than 2 mm.

Abstract: A golf club head includes a metal frame having a sole opening, a composite laminate crown joined to the frame, a composite laminate sole insert joined to the frame and overlying the sole opening, and a thermoplastic composite component overmolded on the sole insert. The composite component may include a weight track, ribs, supports or other features. A method of making the golf club includes the steps of forming a frame having a sole opening, forming a composite laminate sole insert, forming a composite laminate crown insert, injection molding a thermoplastic composite head component over the sole insert to create a sole insert unit, and joining the sole insert unit and crown insert to the frame.
