Abstract

A set of golf club heads having peripheral weights that change from club head to club head so that the center of gravity rises from the long irons to the short irons resulting in a consistent peak trajectory height along a line for each club head.

Claims

1. A set of golf club heads comprising:

a first golf club head comprising a heel, a toe, an upper surface, a lower surface, a front face, and a back face opposite the front face, wherein the first golf club head has a first peripheral weight defining a first cavity, wherein the first peripheral weight has a first thickness corresponding to the upper surface and a second thickness corresponding to the lower surface, and wherein the first cavity comprises an upper cavity weight extending from the upper surface of the first peripheral weight towards the lower surface of the first peripheral weight and a lower cavity weight extending from the lower surface of the first peripheral weight towards the upper surface of the first peripheral weight; and

a second golf club head comprising a heel, a toe, an upper surface, a lower surface, a front face, and a back face opposite the front face, wherein the second golf club head has a second peripheral weight defining a second cavity, wherein the second peripheral weight has a third thickness corresponding to the upper surface and a fourth thickness corresponding to the lower surface, wherein the third thickness is greater than the first thickness, and wherein the second cavity comprises an upper cavity weight extending from the upper surface of the second peripheral weight towards the lower surface of the second peripheral weight and a lower cavity weight extending from the lower surface of the second peripheral weight towards the upper surface of the second peripheral weight, and wherein the upper and lower cavity weights of the first and second cavities have an arch shape gap therebetween.

2. The set of golf club heads of claim 1, wherein the fourth thickness is less than the second thickness.

3. The set of golf club heads of claim 1, wherein the second thickness and fourth thickness are substantially constant.

4. The set of golf club heads of claim 1, wherein the upper and lower cavity weights of the first golf club head extend from the heel to the toe.

5. The set of golf club heads of claim 1, wherein the second cavity further upper and lower cavity weights of the second golf club head extend from the heel to the toe.

6. The set of golf club heads of claim 1, further comprising at least four club heads.

7. A set of golf club heads comprising:

a first golf club head comprising a heel, a toe, an upper surface, a lower surface, a front face, and a back face opposite the front face, wherein the first golf club head has a first peripheral weight defining a first cavity, wherein the first cavity comprises a first cavity weight comprising a first upper cavity weight proximate the upper surface and a first lower cavity weight proximate the lower surface, and wherein the first upper cavity weight and first lower cavity weight have an arch shape gap therebetween; and

a second golf club head comprising a heel, a toe, an upper surface, a lower surface, a front face, and a back face opposite the front face, wherein the second golf club head has a second peripheral weight defining a second cavity, wherein the second cavity comprises a second cavity weight comprising a second upper cavity weight proximate the upper surface and a second lower cavity weight proximate the lower surface, and wherein the second upper cavity weight and second lower cavity weight have an arch shape gap therebetween, and

wherein the first cavity weight has a different weight distribution than the second cavity weight.

8. The set of golf club heads of claim 7, wherein the first lower cavity weight has a first thickness and the second lower cavity weight has a second thickness less than the first thickness.

9. The set of golf club heads of claim 8, wherein the first upper cavity weight has a third thickness and the second upper cavity weight has a fourth thickness greater than the third thickness.

10. The set of golf club heads of claim 7, wherein the first lower cavity weight has a first thickness and the second lower cavity weight has a second thickness, and wherein the first thickness and the second thickness are substantially constant.

11. The set of golf club heads of claim 7, wherein the first upper cavity weight weighs less than the second cavity upper weight.

12. A set of golf clubs comprising:

a plurality of golf clubs, wherein each club comprises;

a shaft; and

a club head, wherein each club head comprises a heel, a toe, an upper surface, a lower surface, a front face, a back face opposite the front face, and a peripheral weight defining a cavity, wherein the peripheral weight comprises an upper portion proximate the upper surface and a lower portion proximate the lower surface, wherein the cavity comprises an upper cavity weight extending from the upper surface towards the lower surface and a lower cavity weight extending from the lower surface towards the upper surface, and wherein the upper and lower cavity weights have an arch shape gap therebetween, and

wherein the plurality of clubs are designed so that as the club number ascends, the upper portion increases in thickness.

13. The set of clubs of claim 12, wherein the thickness of the lower portions are constant throughout the set.

14. The set of clubs of claim 12, wherein the upper cavity weight has a maximum thickness, and wherein the maximum thickness is constant as the club number ascends.

15. The set of clubs of claim 12, wherein the lower cavity weight has a maximum thickness, and wherein the maximum thickness decreases as the club number ascends.

16. The set of clubs of claim 12, wherein the plurality of clubs are designed so that as the club number ascends, the thickness of the upper weight increases.
