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. An iron-type 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 the body around the internal periphery region,

wherein the internal periphery region further comprises;

an engagement portion; and

a non-engagement portion,

wherein the face insert is welded to the body at the internal periphery region only via the engagement portion and spaced away from the body everywhere at the non-engagement portion to define an opening through the club head from an area out in front of the club head to a space out behind the club head and further wherein the engagement portion encompasses less than about 100% of the internal periphery region.

2. The golf club head of claim 1, wherein the engagement portion encompasses less than about 75% of the internal periphery region.

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

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

4. An iron-type golf club head comprising:

a body; and

a face insert comprising an external periphery region, wherein the external periphery region further comprises;

an engagement portion comprising less than 100% of the external periphery region; and

a non-engagement portion, wherein the face is welded to the body via only the engagement portion, and the non-engagement portion is everywhere separated from the body by an empty gap.

5. An iron-type golf club head comprising:

a body; and

a face insert adapted to be connected to a forward portion of the body, the face insert comprising an external periphery region, the external periphery region comprising;

an engagement portion; and

a non-engagement portion,

wherein only the engagement portion of the external periphery region engages the body, the face insert is welded to the body at the engagement portion, and wherein the engagement portion encompasses less than 50% of the external periphery region of the face insert, the golf club head further comprising a separation between the face insert and the body throughout an entirety of the non-engagement portion.

6. The golf club head of claim 5, wherein the separation between the face insert and the body defines an opening through the club head from an area out in front of the club head to a space out behind the club head.

7. The golf club head of claim 5, wherein the engagement portion encompasses less than 25% of the external periphery region of the face insert.

8. An iron-type golf club head comprising:

a body with a heel, a sole, a toe, a top, and a hosel extending from the heel;

a face insert connected to, and surrounded in all directions by, the body; and

a gap between the face insert and the body wherein the gap defines an empty space through the club head from an area out in front of the club head to a space out behind the club head separating the face insert from the body along at least 25% of a perimeter of the face insert.

9. The club head of claim 8, wherein the face insert is welded to the body.

10. The club head of claim 8, wherein the face insert is connected to the body via a plurality of engagement portions disposed along a perimeter of the face insert.

11. The club head of claim 10, wherein a first one of the plurality of the engagement portions is near the sole is wider than a second one of the plurality of the engagement portions near the top.

12. The club head of claim 8, wherein the face insert is connected to the body via an engagement portion that completely covers a toe portion, a heel portion, and a sole portion of a perimeter of the face insert.
