Abstract: A golf club head has a body defining a crown opening and a sole opening, a forward portion of the crown opening having a lip recessed below an outer surface of the crown and extending rearwardly. A composite crown insert is connected to the lip and covers the crown opening. A ratio of an outer surface area of the body and a combined outer surface area of the crown and sole inserts is less than 0.9. The club head has a crown height as measured relative to a ground plane at address, and there is a first crown height at a face-to-crown transition zone, a second crown height at a crown-to-skirt transition zone, and a maximum crown height that is greater than the first and second crown heights, the maximum crown height being located on the crown insert at or rearward of the lip.

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: A golf club head having discreet regions of specific mass relationships, including a lightweight forward portion, to achieve specific mass properties and performance.

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.

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, while the fastener itself, regardless of where the weight member is positioned along the path, is secured to the body at a fixed location that is independent of the position of the weight member along the path. Part of the weight channel and weight member can be covered by an overhanging portion of the sole, which can form a sit pad. The overhanging portion can be part of a composite sole insert.

Abstract: Some disclosed golf club heads include body having at least one raised sole portion and a cantilevered ledge extending down around a perimeter of the club head below the level of the raised sole portion. Some disclosed golf club heads include one or more sole openings in the body and a sole insert that is mounted inside the body over the sole openings. The sole can include weight tracks as well, and a rear weight track can extend between a toe side sole opening and a heel side sole opening. A crown insert can also be included that is mounted over an upper opening in the body.

Abstract: A cast cup can include a forward portion of a golf club head, including a hosel, forward portions of a crown, sole, heel, and toe, and a face portion or an opening to receive a face insert. A rear ring can be formed separately from the cast cup and coupled to heel and toe portions of the cast cup to form a rigid club head body, such that the club head body defines a hollow interior region, a crown opening, a sole opening, and/or face opening. The cast cup and rear ring can be made of different materials, including various metals, composites, and polymers. Composite crown, sole, and/or face inserts can be coupled to the crown, sole, and/or face openings. Weights can be coupled to the cast cup and to the rear ring. The face can have a complex variable thickness geometry.

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: A golf club includes a golf club head having a body defining an interior cavity. The body includes a sole, a crown and a skirt positioned around a periphery between the sole and crown. A face defines a forward portion of the club head and includes a striking surface width and a hosel defining a hosel bore. A channel and a recessed port are positioned in the sole. The channel extends substantially in a heel-to-toe direction. A sleeve is mounted on a tip end of the golf club shaft and is adapted to be inserted into the hosel bore. 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.

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.

Abstract: Aspects of the invention are directed to golf club having a crown, a sole, a face, and a primary alignment feature hard tooled into the golf club head. In some embodiments the golf club has a primary alignment feature comprising a line delineating a transition between at least a portion of the crown having an area of contrasting shade or color with a shade or color of the face. The primary alignment feature is hard tooled into the golf club head with the face of the golf club body.

Abstract: In one embodiment the golf club head includes three main components, a frame component, a rear cap component, and a striking plate. In another embodiment the club head may also comprise a front component, which is manufactured as a single unitary piece, and a rear cap component. The front component may also be overmolded by a thermoplastic polymeric outer portion which may or may not cover the striking face and which provides additional reinforcement at the load bearing sections of the club head and allows a more facile connection to the rear cap component. In another embodiment, a club head having a main body, crown insert, sole insert and metal face plate frame is formed by forming the sole insert and crown insert from a polymeric material using a thermoforming or thermosetting process and then injection molding the main body over the sole insert, crown insert and metal face plate frame.

Abstract: A golf club head comprises a body having a face, a crown and a sole together defining an interior cavity. The body having a head-shaft connection system, a rear weight fastened to the golf club head proximate the rear end of the club head and proximate the Y-Z plane, and a front weight port or an internal cap connection system for securing the rear weight; in combination with specific windows regarding the moments of inertia and center of gravity.
