(Cross reference to related application)
This application claims the benefit of priority from U.S. Provisional Application No. 62/545,770 filed Aug. 15, 2017 and U.S. Provisional Application No. 62/628,803 filed Feb. 9, 2018 and all content disclosed in the above application is incorporated herein by reference.

The present disclosure relates to golf club heads. More particularly, it relates to golf club heads having adjustable weighting systems.

Various properties of a golf club can affect the performance of the golf club. For example, the center of gravity and moment of inertia of a golf club head are properties that can affect performance.

The center of gravity and moment of inertia of a golf club head depend on the mass distribution of the golf club head. In particular, by distributing the mass of the club head closer to the sole of the club head, closer to the hitting face of the club head, and/or closer to the toe and heel of the club head, the club head's center of gravity and/or Or you can change the moment of inertia. By changing the moment of inertia of the club head, the forgiveness of the golf club, the flight direction of the golf ball, and/or the flight angle of the golf ball can be changed.

Many of the weighting systems in existing golf club heads have large, complex internals that reduce the club head's moment of inertia and move the club head's center of gravity upward (towards the crown) and forward (towards the face). Requires structure. Club heads in which the weighting and center of gravity position of the club head can be adjusted by the user to affect ball flight (trajectory and/or spin) without adversely affecting moment of inertia or center of gravity position is needed.

Various embodiments of golf club heads having adjustable weighting systems are described herein. The adjustable weighting system includes multiple discrete mounting positions that can accommodate one or more weights. Each weight is connectable to any of discrete mounting locations on the club head and is movable between any of the mounting locations. This adjustable weighting system thus allows the user to adjust the weighting and center of gravity position of the club head to alter the flight of the ball (ie, the spin or trajectory of the ball).

In many embodiments, the adjustable weighting systems described herein protrude from or minimally inset from the outer contour of the club head. Additionally, in many embodiments, the adjustable weighting systems described herein are placed near the outer edge of the club head. By arranging the adjustable weighting system in this manner, weighting to the outer edge and low rear weight placement can be maximized. This maximizes the club head's moment of inertia for off-center hit forgiveness and allows the club head's center of gravity to be positioned low and rearward, increasing launch angle and reducing backspin. Thus, the golf club heads described herein allow the user to adjust the center of gravity of the club head to control ball flight while maintaining optimal design and performance characteristics (high moment of inertia and low rearward center of gravity location). is adjustable.

Many of the embodiments described herein are adjustable with one or more platforms, ledges, recesses, or channels without requiring significant internal structures that adversely affect moment of inertia and head center-of-gravity position. weighting system.

Various parameters of a golf club head are important in achieving desired performance characteristics such as the club head's moment of inertia, the location of the club head's center of gravity, and the adjustability of the club head's center of gravity. A high club head moment of inertia makes the club head more forgiving of off-center hits. Locating the club head's center of gravity low and rearward (i.e., toward the sole and rear of the club head) beneficially increases moment of inertia, reduces backspin, and increases golf ball launch at impact. angle increases. The adjustability of the club head's center of gravity allows the end user to adjust the trajectory of the club head as desired. Each of these parameters is important in golf club design in order to achieve desired or optimal performance characteristics. However, many existing center-of-gravity adjustment mechanisms either (1) lower the club head's moment of inertia and/or (2) internal weight structures and/or large weight structures and/or non-optimal placement of weight structures. Including all of the above parameters of a golf club head presents a design challenge because it moves the center of gravity of the club head up and forward of the club head due to .

The golf club head embodiments described below include an adjustable weighting system while maintaining or preventing a significant reduction in club head moment of inertia and a low, rearward club head center of gravity location. For example, many of the embodiments below provide the user with adjustability of ball flight and/or trajectory, while providing the club head with a high moment of inertia and low rearward weighting system, similar to a club head lacking an adjustable weighting system. A low profile adjustable weighting system and/or an optimally placed adjustable weighting system is described for maintaining the center of gravity of the club head at a constant position.

In other embodiments, cable 13069 may be retracted by means other than tensioner 13067 .

The club head 13010 described above having an adjustable weighting system 13066 with tensioner 13067 (or other cable adjustment means) and cable 13069 can optimize the performance of the golf club. Similar to a club head without an adjustable weighting system, the adjustable weighting system 13066 allows club head 13010 to adjust the x-axis (heel-toe end) without sacrificing a high moment of inertia (MOI). Weight adjustment is possible for club heads that have a low center of gravity around them. By moving the CG around the x-axis, the player can correct for slices or hooks in the ball trajectory.

Adjustable weighting with tensioner 13067 and cable 13069 compared to club heads with more complex structures to accommodate weights (e.g., deep weight ports, multiple weight ports, rail systems, weight covers/caps) Club head 13010 with system 13066 has additional utility in terms of ease of manufacture. Weight 13082 coupled to club head body 13014 is held in place by the tension of cable 13069 , thus exerting a force on weight 13082 on feature 13070 of club head 13010 . The tension-induced force can eliminate the need to manufacture the club head 13010 with a weight housing structure having complex internal/external geometries to secure the weight 13082 . Accordingly, the materials and mass associated with complex weight housing structures can be reduced. And the reduced mass by using a low profile adjustable weighting system is placed elsewhere in the club head to increase strength and/or MOI and improve CG location. good. The force created by tension in the cable 13069 can further eliminate the need for threaded fasteners, thus requiring the weight 13082 and club head 13010 to be manufactured with threaded holes and receiving features to receive the fasteners. do not have. The lack of fasteners and threaded holes reduces manufacturing costs and improves manufacturing ease.

Additionally, the cables 13069 of the adjustable weighting system 13066 are lightweight, strong, and can be incorporated into many different patterns of recesses 13080 in the club head 13010. Because weights 13082 are not limited to a particular weight housing configuration, different patterns allow weights 13082 to be placed at many different locations on sole 13030 . Various weight positions allow fine-tuning of CG placement and ball spin and trajectory tuning for individual players. Cables 13069 may also be strategically placed in patterns that allow the cables to reinforce specific locations of club head 13010 . The material and pattern of the cable 13069 may also act as a sound dampener and absorb vibrations experienced by the club head 13010 during impact, thereby reducing unwanted sounds and stress during a game.
