Abstract

A set of golf club irons with improved vibration damping and weight distribution, each golf club comprising a shaft and a head comprising a body portion having a front portion and a back portion, wherein the body portion defines an upper aperture and a lower aperture extending through the body portion communicating with the front portion and the back portion.

Claims

1. A set of golf clubs, comprising a plurality of clubs wherein each of the plurality of clubs comprises a shaft and a club head, the shaft of each club being shorter in length than the shaft of a preceding club in the plurality of clubs, wherein:

each of the plurality of club heads has a front portion and a back portion;

the front portion defines a front cavity therein;

the back portion defines a back cavity therein;

the front cavity has a third cavity formed within;

the back cavity has an upper aperture therein communicating with the front cavity;

the back cavity has a lower aperture therein communicating with the third cavity; and

a strike face insert is attached within the front cavity.

2. The set of golf clubs of claim 1, wherein a vertical position of a center of gravity of the club head progressively elevates for at least some clubs in the set.

3. The set of golf clubs of claim 1, wherein each of the plurality of club heads has a vibration dampening and/or acoustic attenuating member occupying the entire third cavity, the entire lower aperture and a portion of the back cavity.

4. The set of golf clubs of claim 3, wherein the vibration damping and/or acoustic attenuating member comprises a plurality of layers and a plurality of materials.

5. The set of golf clubs of claim 3, wherein the strike face insert is progressively larger for at least some clubs in the set.

6. The set of golf clubs of claim 3, wherein the upper aperture is surrounded by a shelf having a first volume of material, and wherein the first volume of material progressively increases for at least some clubs in the set.

7. The set of golf clubs of claim 3, wherein the lower aperture is surrounded by a rim having a second volume of material, and wherein the second volume of material progressively increases for at least some clubs in the set.

8. The set of golf clubs of claim 3, wherein a volume of the upper aperture progressively decreases for at least some clubs in the set.

9. The set of golf clubs of claim 3, wherein a volume of the third cavity progressively decreases for at least some clubs in the set.

10. The set of golf clubs of claim 3, wherein a volume of the lower aperture progressively decreases for at least some clubs in the set.

11. The set of golf clubs of claim 3, wherein a vertical position of the upper aperture progressively decreases for at least some clubs in the set.

12. The set of golf clubs of claim 3, wherein a vertical position of the third cavity progressively decreases for at least some clubs in the set.

13. The set of golf clubs of claim 3, wherein a vertical position of the lower aperture progressively decreases for at least some clubs in the set.

14. The set of golf clubs of claim 3, wherein a density of the vibration damping and/or acoustic attenuating member progressively increases for at least some clubs in the set.

15. The set of golf clubs of claim 3, wherein a volume of the vibration damping and/or acoustic attenuating member progressively increases for at least some clubs in the set.

16. The set of golf clubs of claim 3, wherein the vibration damping and/or acoustic attenuating member further contains a weight member therein.

17. The set of golf clubs of claim 3, wherein a volume of the weight member progressively increases to elevate a vertical position of a center of gravity of the club head for at least some clubs in the set.

18. The set of golf clubs of claim 3, wherein a density of the weight member progressively increases to elevate a vertical position of a center of gravity of the club head for at least some clubs in the set.

19. The set of golf clubs of claim 3, wherein a vertical position of the weight member progressively increases to elevate a vertical position of a center of gravity of the club head for at least some clubs in the set.
