Abstract

Described herein is a golf club head comprising a composite material, the golf club head further comprising: a front end having a bottom rail, a top rail, and a strikeface, the strikeface including a striking surface, a back surface, and a reinforcement element extending from the back surface of the strikeface; a rear end opposite the front end; a heel portion; a toe portion opposite the heel portion; a sole coupled to the front end along the bottom rail at a sole transition region, the sole extending toward the rear end of the golf club head and including a sole thickness, a first weight member and a second weight member, and a perimeter wall extending from the front end near the heel portion to the front end near the toe portion along the rear end of the golf club head, wherein the perimeter wall decreases in height from the front end toward the rear end of the golf club head.

First claim

The invention claimed is:

1. A golf club head comprising;
a front end having a bottom rail, a top rail and a strikeface;
wherein the strikeface comprises;
a striking surface;
a back surface;
wherein the back surface of the strikeface comprises a reinforcement element;
wherein the reinforcement element comprises a looped rib;
wherein the looped rib comprises an outer perimeter surface and an inner perimeter surface;
wherein the outer perimeter surface is filleted with the back surface of the strikeface;

a rear end opposite the front end;
a heel portion;
a toe portion opposite the heel portion;
a sole coupled to the front end along the bottom rail at a sole transition region, the sole extending toward the rear end of the golf club head;
wherein the sole comprises;
a sole thickness;
a first weight member and a second weight member, wherein:
the first weight member is positioned toward the toe portion;
the second weight member is poisoned toward the heel portion;

a perimeter wall extending from the front end near the heel portion to the front end near the toe portion along the rear end of the golf club head; wherein;
the perimeter wall defines at least a first recess towards the heel portion and at least a second recess towards the toe portion; wherein,

the golf club head is devoid of a crown; and
the back surface of the strikeface and a top surface of the sole are exposed.

2. The golf club head of claim 1 , wherein the perimeter wall further comprises a perimeter wall thickness and a perimeter height;
wherein;
at least one of the perimeter wall thickness or the perimeter wall height varies to form the first recess or the second recess.

3. The golf club head of claim 2 , wherein the golf club head further includes:
a length measured as a greatest distance from a front plane to the rear end of the golf club head in a direction parallel to a ground; and
at least one of the first recess or the second recess is positioned within 60% of the length of the club head from the front end.

4. The golf club head of claim 2 , wherein the perimeter wall thickness ranges from 0.020-0.100 inches (0.051-0.254 cm).

5. The golf club head of claim 1 , wherein the first weight member comprises a first volume, and the second weight member comprises a second volume, wherein a greater portion of the first volume is positioned towards the toe portion and a greater portion of the second volume is positioned towards the heel portion.

6. The golf club head of claim 1 , wherein the first weight member and second weight member are formed integrally with the golf club head.

7. The golf club head of claim 1 , wherein the first weight member and second weight member are formed separately from the golf club head.

8. The golf club head of claim 7 , wherein the first weight member and the second weight member comprise a material different from the material of the golf club head.

9. The golf club head of claim 1 , wherein the perimeter wall further comprises a lip extending along the perimeter wall from the front end near the heel portion to the front end near the toe portion along the rear end of the golf club head;
wherein;
the lip comprises a lip thickness and a lip height; and at least one of the lip thickness or the lip height varies to form at least one of the first recess or the second recess.

10. The golf club head of claim 1 , wherein at least one of the first weight member and the second weight member comprises a circular rectangular shape.

11. The golf club head of claim 1 , wherein at least one of the first weight member and the second weight member comprises an ovular shape.
