Abstract

Ball striking devices, such as golf clubs, have a head that includes a face having a striking surface configured for striking a ball, and a body connected to the face and extending rearwardly from the face, with the body having a crown, a sole, a heel side, and a toe side, such that the face and the body combine to define an enclosed internal cavity. A damping member is connected to the body and includes a post extending inwardly into the cavity from an inner surface of the body, a first arm extending from the post toward the heel side of the body, and a second arm extending from the post toward the toe side of the body. The damping member is configured to produce a mass damping effect upon an impact on the face.

First claim

What is claimed is:

1. A ball striking device comprising:
a face having a striking surface configured for striking a ball,
the face having a heel portion and a toe portion; a body connected to the face and extending rearwardly from the face,
the body having a crown, a sole, a heel side, and a toe side,
wherein the face and the body combine to define an enclosed internal cavity; and
wherein the body has an opening in the sole,
wherein a removable panel is received in the opening,
wherein the removable panel is removably connected to the body by a plurality of removable fasteners,
a damping member connected to the removable panel,
wherein when the removable panel is connected to the body, the damping member comprises a single post extending inwardly from the removable panel within the enclosed internal cavity,
wherein the single post has a first fixed end that is attached to the removable panel and a top end;
wherein the damping member comprises an adjustment mechanism;
a first arm extending from the single post toward the heel side of the body,
and a second arm extending from the single post toward the toe side of the body,
wherein the adjustment mechanism adjusts an angle between the first arm and the second arm;
wherein the damping member is configured to produce a mass damping effect upon an impact on the face,
wherein the first arm further comprises a first weight member connected to the first arm and the second arm further comprises a second weight member connected to the second arm,
wherein the first and second weight members have greater densities than the single post.

2. The ball striking device of claim 1 , wherein the adjustment mechanism comprises a locking member on the first arm and a locking member on the second arm;
wherein the locking members on each arm have locking teeth that face each other and engage each other to lock the first arm and the second arm in position relative to each other.

3. The ball striking device of claim 2 , wherein the locking members are connected to the single post by receiving the single post through an opening in each locking member.

4. The ball striking device of claim 3 , wherein the adjustment mechanism further comprises a biasing member engaging one of the locking members to push the locking members into engagement with each other.

5. The ball striking device of claim 4 , wherein the biasing member is a spring.

6. The ball striking device of claim 4 , wherein the adjustment mechanism further comprises a flange; wherein the biasing member compresses the locking member against the flange.

7. The ball striking device of claim 6 , wherein the flange further comprises a flange locking member for rotational locking;
wherein the flange locking member comprises locking teeth complementary with the second arm locking mechanism.

8. The ball striking device of claim 1 , wherein the first and second arms are oriented at approximately 180° to each other.

9. A golf club comprising the ball striking device of claim 1 , wherein the ball striking device is a golf club head, and a shaft connected to the ball striking device.

10. A golf club comprising the ball striking device of claim 1 , wherein the first and second weight members are spherical.

11. A golf club comprising the ball striking device of claim 1 , wherein the first and second weight members are cylindrical.

12. A golf club comprising the ball striking device of claim 1 , wherein the first weight member has a threaded hole to receive the first arm, and
wherein the second weight member has a threaded hole to receive the second arm,
wherein the first and second arms are threaded.

13. A golf club comprising the ball striking device of claim 1 , wherein the positions of the first and second weight members can be adjusted on the first and second arms to achieve translational motion.

14. A golf club comprising the ball striking device of claim 1 , wherein the first and second weight members can be removed and interchanged with other weight members.

15. A golf club comprising the ball striking device of claim 1 , wherein the first and second arms have tracks along their length, and
wherein the first and second weight members are attached to fasteners received in the tracks of the first and second arms.

16. A golf club comprising the ball striking device of claim 15 , wherein the first and second weight members can be moved along the length of first and second arms by loosening and retightening the fasteners received in the tracks of the first and second arms.

17. A golf club comprising the ball striking device of claim 1 , wherein the single post is detachably attached from the removable panel such that different dampening members may be attached to the removable panel.
