Abstract

The invention provides a golf club head with a fully removable component that can withstand the stress of repeated hits. When assembled, the removable component is held in place by a fastening mechanism that includes structural elements that distribute the holding force across the component and tend to equalize the forces around the periphery where the component meets the body. The fastening mechanism may include a post that reaches across the open space within the hollow club head, pulling the removable component towards an opposed main club head body. Since a golf club of the present invention can be opened, it may include a mechanism on the inside for use by a golfer, such as an electronic device or an adjustment mechanism. The golf club may include a weight adjustment system that allows the club to be custom-fitted to a golfer.

Claims

1. A golf club head comprising:

a hosel, a ball-striking face, a crown, and a sole;

a club head body member defining a portion of the golf club head; and

a removable component removably coupleable to the club head body member to create a playable club.

2. The club head of claim 1, wherein the club head body member includes a boss with a screw extending therethrough, the screw being threadably engaged with the removable component.

3. The golf club of claim 2, further comprising a washer disposed around the screw and retaining the screw within the boss.

4. The club head of claim 1, further comprising at least one mount point on an inside surface of the main club head body.

5. The club head of claim 4, further comprising a removable weight attached to the mount point.

6. The club head of claim 5, further comprising a plurality of mount points, wherein the removable weight can be threadably attached to any one of the plurality of mount points.

7. The club head of claim 4, wherein the mount point comprises a casting and a threaded insert disposed within the casting.

8. The club head of claim 1, wherein the removable component comprises at least a majority of a crown of the club head and extends into at least a portion of the sole.

9. The club head of claim 8, wherein the club head body member comprises a face cup, a hosel, and at least a portion of a sole of the club head.

10. The club head of claim 9, wherein the club head body member comprises a majority of the sole.

11. The club head of claim 1, wherein the attachment perimeter includes a plurality of tabs and corresponding recesses.

12. The club head of claim 1, wherein the body member comprises a first piece defining the hosel and surrounding the ball-striking face, and an intermediate piece connected to the first and defining a cutaway with an inner periphery defining an attachment perimeter for attaching the removable component.

13. The club head of claim 1, wherein the removable component is coupled to the body by a screw that extends through an enclosed volume of space inside of the club head and is substantially vertical when the club head is at address.

14. The club head of claim 1, wherein when the removable component is coupled to the club head body, the club head defines an enclosed interior space throughout the club head with a single assembly screw extending from the crown to the sole across the enclosed interior space.

15. A system for fitting a golf club, the system comprising:

a hollow golf club head defining a portion of a crown, a sole, a hosel, and a ball striking face, the hollow golf club head comprising a main body with a cutaway defining an opening and a removable component removably coupled to the cutaway to enclose the opening;

a plurality of mount points disposed on an inner surface of the golf club head; and

at least one weight member releasably coupleable to any of the plurality of mount points, wherein the removable component provides for accessing an interior of the club head.

16. The system of claim 15, wherein the plurality of mount points includes at least one mount point on a toe-side of an inside surface of the sole and at least one mount point on a heel side of an inside surface of the sole.

17. The system of claim 15, wherein the plurality of mount points includes at least one mount point on a forward area of an inside surface of the sole and at least one mount point on an aft area of an inside surface of the sole.

18. The system of claim 15, wherein each mount point comprises a raised casting with a threaded insert therein.

19. The system of claim 15, wherein the at least one weight member comprises a rigid body;

a viscoelastic dampener on a mounting side of the rigid body;

a threaded post extending from the mounting side; and

a tool interface obverse to the threaded post.

20. The system of claim 19, wherein the weight member further comprises a screw extending through the rigid body and providing the threaded post;

and a retaining washer holding the screw in the rigid body.

21. A golf club head comprising:

a hosel, a ball-striking face, a crown, and a sole;

a main club head body member defining a portion of the golf club head; and
