Abstract

The invention includes a releasable component for use on a golf club head, wherein the component itself may serve as a portion of the club head face, crown, sole, or other portion of the club head body when attached to the club head. The component includes an anti-over rotation mechanism configured to prevent overtightening of the component to a corresponding counterbore on the golf club head. The anti-over rotation mechanism is embodied as a taper design defined on a flange of a threaded component and a corresponding taper design on a flange surface of a counterbore. The counterbore is configured to receive and retain the releasable component by way of a threaded engagement, wherein the interaction between the corresponding taper flange designs of the releasable component and counterbore prevents over rotation of the releasable component, particularly resisting rotation due to ball strike impacts.

First claim

What is claimed is:

1. A golf club head comprising:
a club head body comprising a crown, a sole, a heel, a toe, and a ball-striking face, the club head body having at least one internally threaded mounting portion; and
a releasable component configured to be releasably coupled to the mounting portion on the club head body, the releasable component having a component body comprising:
an externally threaded distal end configured to engage the internally threaded mounting portion of the club head body;
a proximal end having a flange member for engaging a corresponding flange member of the mounting portion upon threaded engagement with the mounting portion, wherein the flange member of the releasable component has a surface profile configured to prevent over rotation of the component when engaged with the flange member of the mounting portion; and
a port configured to provide a view from the exterior of the club head into an interior cavity of the club head body when the component is coupled to the mounting portion;

wherein the component is selected from a group consisting of a crown panel, a sole panel, a heel panel, a toe panel, a skirt panel, a face insert, a damping insert, a weight member, and a combination of at least two thereof.

2. The golf club head of claim 1 , wherein the surface profile comprises at least one raised portion and at least one lowered portion along a length of the flange member.

3. The golf club head of claim 2 , wherein the surface profile comprises at least two raised portions and at least two lowered portions along a length of the flange member.

4. The golf club head of claim 3 , wherein the raised portions and lowered portions alternate relative to one another along the length of the flange member such that one raised portion is adjacent to one lowered portion.

5. The golf club head of claim 2 , wherein a total elevation change between the at least one raised portion and the at least one lowered portion is based, at least in part, on a thread pitch of the externally threaded distal end of the component body.

6. The golf club head of claim 5 , wherein a total elevation change between the at least one raised portion and the at least one lowered portion is approximately equal to the thread pitch.

7. The golf club head of claim 5 , wherein a total elevation change between the at least one raised portion and the at least one lowered portion is between 25 percent and 75 percent of the thread pitch.

8. The golf club head of claim 2 , wherein the flange member of the mounting portion has a surface profile configured to interact with the surface profile of the releasable component flange member to prevent over rotation of the component when engaged with the mounting portion.

9. The golf club head of claim 8 , wherein the at least one raised portion and the at least one lowered portion of the surface profile of the releasable component flange member are configured to mate with corresponding lowered and raised portions of the surface profile of the mounting portion flange member, respectively.

10. The golf club head of claim 9 , wherein engagement between the corresponding surface profiles of the flange members of the releasable component and mounting portion is sufficient to resist over rotation upon at least one of vibration and elastic deformation due to impact forces imparted upon the golf club head.
