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;

the third cavity has a greater height than the lower aperture;

the upper and lower apertures are the only two apertures extending from the back cavity towards the front cavity;

each of the plurality of club heads has a vibration dampening and acoustic attenuating member occupying the entire third cavity, the entire lower aperture, and a portion of the back cavity;

means for progressively elevating the vertical position of a center of gravity of the club head for at least some of the clubs in the set; and

a strike face insert is attached within the front cavity.

2. The set of golf clubs of claim 1, wherein the means for elevating the vertical position of the center of gravity is by progressively decreasing the vertical position of the upper aperture for at least some clubs in the set.

3. The set of golf clubs of claim 1, wherein the means for elevating the vertical position of the center of gravity is by progressively decreasing the vertical position of the third cavity for at least some clubs in the set.

4. The set of golf clubs of claim 1, wherein the means for elevating the vertical position of the center of gravity is by progressively decreasing the vertical position of the lower aperture for at least some clubs in the set.

5. The set of golf clubs of claim 1, wherein the means for elevating the vertical position of the center of gravity is by progressively increasing the density of the vibration dampening and acoustic attenuating member for at least some clubs in the set.

6. The set of golf clubs of claim 1, wherein the means for elevating the vertical position of the center of gravity is by progressively increasing the volume of the vibration dampening and acoustic attenuating member for at least some clubs in the set.

7. The set of golf clubs of claim 1, wherein the means for elevating the vertical position of the center of gravity is by progressively increasing the volume of the weight member for at least some clubs in the set.

8. The set of golf clubs of claim 7, wherein the means for elevating the vertical position of the center of gravity is by progressively increasing the density of the weight member for at least some clubs in the set.

9. The set of golf clubs of claim 7, wherein the means for elevating the vertical position of the center of gravity is by progressively increasing the vertical position of the weight member for at least some clubs in set.

10. 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;

the third cavity has a greater height than the lower aperture;

the upper and lower apertures are the only two apertures extending from the back cavity towards the front cavity;

each of the plurality of club heads has a vibration dampening and acoustic attenuating member occupying the entire third cavity, the entire lower aperture, and a portion of the back cavity, the vibration dampening and acoustical attenuating member having a weight member included therein;

means for progressively elevating the vertical position of a center of gravity of the club head for at least some of the clubs in the set; and

a strike face insert is attached within the front cavity.
