Abstract

Golf club heads with patterned face plates described herein. Other examples, embodiments and related methods are also disclosed herein.

Claims

1. A golf club head comprising:

a face plate having a contoured rear surface, the contoured rear surface including a central thickened region having a first non-circular, elliptical outer edge surrounded by a transition region tapered from the central thickened region toward a thinner peripheral region, the transition region having a second non-circular, elliptical outer edge,

wherein the first non-circular, elliptical outer edge has a first aspect ratio, a first major axis and a first minor axis,

wherein the second non-circular, elliptical outer edge has a second aspect ratio, a second major axis and a second minor axis, the second major axis being equal to the first major axis plus a predetermined distance and the second minor axis being equal to the first minor axis plus the predetermined distance,

wherein the first aspect ratio is greater than the second aspect ratio, and

wherein the first aspect ratio is greater than 1.4 and less than 4.2.

2. The golf club head of claim 1, wherein the central thickened region comprises a constant thickness.

3. The golf club head of claim 1, wherein the central thickened region is greater than 0.13 inch and less than 0.18 inch in thickness.

4. The golf club head of claim 1, wherein the thinner peripheral region is greater than 0.08 inch and less than 0.12 inch in thickness.

5. The golf club head of claim 1, wherein the first major axis is greater than 0.65 inch and less than 1.05 inches in length.

6. The golf club head of claim 1, wherein the first minor axis is greater than 0.25 inch and less than 0.45 inch in length.

7. The golf club head of claim 1, wherein the predetermined distance is greater than 0.40 inch and less than 1.20 inches.

8. The golf club head of claim 1, wherein the faceplate is comprised of a titanium alloy.

9. A golf club head comprising:

a face plate having a contoured surface, the contoured surface including a central region having a first elliptical outer edge surrounded by a transition region extended from the central region to a peripheral region, the transition region having a second elliptical outer edge,

wherein the first elliptical outer edge has a first aspect ratio, a first major axis and a first minor axis,

wherein the second elliptical outer edge has a second aspect ratio, a second major axis and a second minor axis, the second major axis being equal to the first major axis plus a predefined distance and the second minor axis being equal to the first minor axis plus the predefined distance, and the second aspect ratio being less than the first aspect ratio,

wherein the transition region comprises a substantially constant width throughout the transition region and between the first and second elliptical outer edges,

wherein the predetermined distance is greater than 0.40 inch and less than 1.20 inches.

10. The golf club head of claim 9, wherein the transition region has a curved surface extending from the first elliptical outer edge to the second elliptical outer edge.

11. The golf club head of claim 10, wherein the curved surface of the transition region is curved inward from the first elliptical outer edge to the second elliptical outer edge.

12. The golf club head of claim 10, wherein the curved surface of the transition region is curved outward from the first elliptical outer edge to the second elliptical outer edge.
