Abstract

A golf club head with a face insert that is only partially connected to the body of the golf club head is disclosed herein. More specifically, the present invention discloses a golf club head with a face insert wherein the face insert is only connected to the body of the golf club head at specific engagement portions around the perimeter of the face insert while keeping the remainder of the perimeter unengaged. The golf club head disclosed in accordance with the present invention will allow for removal of excessive weight traditionally needed to connect the face insert to the body of the golf club head, therefore improving the performance of the golf club head.

Claims

1. A golf club head comprising:

a body with an opening defining an internal periphery region and a face insert adapted to be connected to a forward portion of said body around said internal periphery region;

wherein said internal periphery region further comprises;

an engagement portion; and

a non-engagement portion;

a vibration dampening material sandwiched between said body and said face insert at said non-engagement portion of said golf club head, the vibration dampening material filling a part of the non-engagement portion and a remainder of the non-engagement portion comprises at least one opening from a face of the golf club head to a back of the golf club head, and

wherein said face insert is adapted to be connected to said body at said internal periphery region only via said engagement portion and separated from said body along said non-engagement portion; and

wherein said engagement portion encompasses less than about 100% of said internal periphery region.

2. The golf club head of claim 1, wherein said at least a part of a bottom sole portion of the non engagement portion is filled with the vibration dampening material and the non-engagement portion further comprises at least one empty gap between said face insert and said engagement portion of said internal periphery region.

3. The golf club head of claim 1, wherein said face insert is connected to said body at said engagement portion of said internal periphery region by being one selected from the list consisting of:

welded, swaged, and screwed together.

4. The golf club head of claim 1, wherein said engagement portion encompasses less than about 90% of said internal periphery region.

5. The golf club head of claim 4, wherein said engagement portion encompasses less than about 75% of said internal periphery region.

6. The golf club head of claim 5, wherein said engagement portion encompasses less than about 50% of said internal periphery region.

7. The golf club head of claim 6, wherein said engagement portion encompasses less than about 25% of said internal periphery region.

8. The golf club head of claim 1, wherein said golf club head has an engagement ratio of less than about 1;

wherein said engagement ratio is calculated by dividing a percentage of said internal periphery region covered by said engagement portion by a percentage of said internal periphery region covered by said non-engagement portion.
