Abstract

A set of golf clubs having a plurality of construction types. The clubs of each construction type are constructed to have a volumetric bias in a pre-selected range.

Claims

1. A set of golf clubs, comprising:

a first golf club including a first club head having a first striking face, a first construction type, a first volume and a first volumetric bias relative to a face center of the first striking face;

a second golf club including a second club head having a second striking face, a second construction type, a second volume and a second volumetric bias relative to a face center of the second striking face; and

a third golf club including a third club head having a third striking face, a third construction type, a third volume and a third volumetric bias relative to a face center of the third striking face,

wherein the first volume is greater than the second volume and the first volumetric bias is less than the second volumetric bias and wherein a center of gravity of each club head is spaced rearward from the striking face of the club head.

2. The set of golf clubs of claim 1, wherein the third volume is less than the first volume and the third volumetric bias is less than the second volumetric bias.

3. The set of golf clubs of claim 1, wherein the first volumetric bias is in a range of 1.20 to 3.30, the second volumetric bias is in a range of 0.50 to 5.90, and the third volumetric bias is in a range of 1.90 to 5.00.

4. The set of golf clubs of claim 3, wherein the first volumetric bias is in a range of 1.25 to 1.70, the second volumetric bias is in a range of 5.25 to 5.90, and the third volumetric bias is in a range of 1.95 to 2.90.

5. The set of golf clubs of claim 1, wherein the first club head has a fourth volumetric bias relative to the hosel axis that is less than a fifth volumetric bias relative to the hosel axis of the second club head, which is less than a sixth volumetric bias relative to the hosel axis of the third club head.

6. The set of golf clubs of claim 5, wherein the fourth volumetric bias is in a range of 0.90 to 1.45, the fifth volumetric bias is in a range of 1.45 to 2.10, and the sixth volumetric bias is in a range of 1.85 to 2.85.

7. The set of golf clubs of claim 6, wherein the fourth volumetric bias is in a range of 1.05 to 1.30, the fifth volumetric bias is in a range of 1.60 to 1.95, and the sixth volumetric bias is in a range of 2.00 to 2.60.

8. The set of golf clubs of claim 1, wherein the first construction type is a utility-type construction, the second construction type is a hybrid-type construction, and the third construction type is an iron-type construction.

9. The set of golf clubs of claim 8, wherein the first volume is in a range of 85 cubic centimeters to 300 cubic centimeters, the second volume is in a range of 60 cubic centimeters to 90 cubic centimeters, and the third volume is in a range of 45 cubic centimeters to 80 cubic centimeters.

10. The set of golf clubs of claim 9, wherein the first volume is in a range of 95 cubic centimeters to 110 cubic centimeters, the second volume is in a range of 70 cubic centimeters to 80 cubic centimeters, and the third volume is in a range of 55 cubic centimeters to 70 cubic centimeters.

11. The set of golf clubs of claim 1, wherein the third construction-type is an iron-type construction and the third volume is between 45 cubic centimeters and 80 cubic centimeters.

12. The set of golf clubs of claim 1, wherein the first golf club has a loft angle in a range of 19 degrees to 28 degrees, the second golf club has a loft angle in a range of 29 degrees to 35 degrees, and the third golf club has a loft angle in a range of 36 degrees to 65 degrees.

13. The set of golf clubs of claim 1, wherein the third club head comprises a body defining a cavity, a silicone material filling at least a portion of the cavity and a polycarbonate insert attached to the silicone material.

14. A set of golf clubs, comprising:

a first plurality of golf clubs, wherein each of the first plurality of golf clubs includes a club head having a volumetric bias relative to a face center of a striking face in a range of 1.25 to 1.70; and

a second plurality of golf clubs, wherein each of the second plurality of golf clubs includes a club head having a volumetric bias relative to a face center of a striking face in a range of 1.95 to 2.90,

wherein the first plurality of golf clubs comprise generally hollow club heads and wherein a center of gravity of each club head is spaced rearward from the striking face of the club head.

15. The set of golf clubs of claim 14, further comprising a third plurality of golf clubs, wherein each of the third plurality of golf clubs includes a club head having a volumetric bias relative to a face center of a striking face in a range of 5.25 to 5.90.

16. The set of golf clubs of claim 15, wherein the first plurality of golf clubs have loft angles in a range of 19 degrees to 28 degrees, the second plurality of golf clubs have loft angles in a range of 36 degrees to 65 degrees, and the third plurality of golf clubs have loft angles in a range of 29 degrees to 35 degrees.

17. The set of golf clubs of claim 14, wherein the first plurality of golf clubs have a utility-type construction, the second plurality of golf clubs have an iron-type construction, and the third plurality of golf clubs have a hybrid-type construction.

18. The set of golf clubs of claim 15, wherein the club heads of the first plurality of golf clubs have volumes in a range of 85 cubic centimeters to 300 cubic centimeters, the club heads of the second plurality of golf clubs have volumes in a range of 45 cubic centimeters to 80 cubic centimeters, and the club heads of the third plurality of golf clubs have volumes in a range of 60 cubic centimeters to 90 cubic centimeters.

19. The set of golf clubs of claim 18, wherein the club heads of the first plurality of golf clubs have volumes in a range of 95 cubic centimeters to 110 cubic centimeters, the club heads of the second plurality of golf clubs have volumes in a range of 55 cubic centimeters to 70 cubic centimeters, and the club heads of the third plurality of golf clubs have volumes in a range of 70 cubic centimeters to 80 cubic centimeters.
