Abstract

A golf club head comprising a hinged face component is disclosed herein. The face component is preferably a partial face cup with striking face, a flange, and a grooved hinge region between the striking face and the flange, which allows the striking face to flex and improves the sound of the striking face when it makes contact with a golf ball. The face component can be L-shaped, r-shaped, or cup shaped, and the groove preferably extends along the entire horizontal length of at least one hinge. In other embodiments, the groove may extend along a horizontal midline of the rear surface of the face cup striking face.

First claim

We claim:

1. A putter-type golf club head comprising:
a body comprising a heel end, a toe end, an aft end, a face, a crown, a sole, and a recess; and
an L-shaped face insert comprising face portion, a sole portion, and a hinge portion,
wherein the recess comprises a face region and a sole region,
wherein the hinge portion comprises a groove,
wherein the groove is disposed in an outer surface of the hinge portion,
wherein the face portion is disposed in the face region and the sole portion is disposed in the sole region,
wherein the sole portion is affixed to the body within the sole region, and
wherein the face portion is not affixed to the body.

2. The putter-type golf club head of claim 1 , wherein the groove extends along an entire horizontal length of the hinge portion.

3. The putter-type golf club head of claim 1 , wherein each of the body and the face insert is composed of one or more metal materials, and wherein the sole portion is welded to the body within the sole region.

4. The putter-type golf club head of claim 1 , wherein the body further comprises a sound chamber.

5. The putter-type golf club head of claim 4 , wherein the sound chamber comprises a primary chamber and a secondary chamber, wherein the primary chamber communicates with the recess, and wherein the body, the sound chamber, and the face insert amplify the sound generated by the putter-type golf club head striking a golf ball.

6. The putter-type golf club head of claim 1 , wherein the face portion of the face insert has a variable thickness pattern.

7. A putter-type golf club head comprising:
a body comprising a heel end, a toe end, an aft end, a face, a top portion, a sole portion, and a recess; and
a partial face cup comprising a face portion, a crown portion, a sole portion, and a hinge portion disposed between the face portion and the crown portion,
wherein the hinge portion comprises a groove,
wherein the groove is disposed in an external surface of the hinge portion,
wherein the recess comprises a face region and a sole region,
wherein the crown portion is affixed to the body within the face region at a location proximate the top portion, and
wherein the face portion and the sole portion are not affixed to the body.

8. The putter-type golf club head of claim 7 , wherein the groove extends along an entire horizontal length of the hinge portion.

9. The putter-type golf club head of claim 7 , wherein each of the body and the face insert is composed of one or more metal materials, and wherein the face insert is welded to the body.

10. The putter-type golf club head of claim 7 , wherein the face portion of the face insert comprises a rear surface and a groove, and wherein the groove extends along a horizontal midline of the rear surface.

11. The putter-type golf club head of claim 7 , wherein the body further comprises a sound chamber, wherein the sound chamber comprises a primary chamber and a secondary chamber, wherein the primary chamber communicates with the recess, and wherein the body, the sound chamber, and the face insert amplify the sound generated by the putter-type golf club head striking a golf ball.

12. A putter-type golf club head comprising:
a body comprising a heel end, a toe end, an aft end, a face portion, a rear surface opposite the face portion, a crown portion, and a sole portion;
a face insert; and
at least two pins,
wherein the face portion comprises a recess having the same approximate size and shape as the face insert,
wherein the at least two pins are disposed within the recess and connect the face insert to the body,
wherein the at least two pins space the face insert from the body,
wherein the face insert is capable of pivoting around the at least two pins, and
wherein the face insert does not make contact with any portion of the body.

13. The putter-type golf club head of claim 12 , wherein the recess comprises an upper toe-side corner, an upper heel-side corner, a lower toe-side corner, and a lower heel-side corner, wherein the at least two pins comprises a first pin and a second pin, wherein the first pin is at least partially disposed in the upper toe-side corner, and wherein the second pin is at least partially disposed in the upper heel-side corner.

14. The putter-type golf club head of claim 12 , wherein each of the body, the face insert, and the at least two pins is composed of a metal material, wherein the at least two pins are welded to the body, and wherein the face insert is welded to the at least two pins.

15. The putter-type golf club head of claim 12 , wherein the face insert is spaced a distance of at least 0.005 inch and no more than 0.100 inch from the face portion along a horizontal axis extending from the face portion through the aft end of the body.
