Abstract

Embodiments of a golf club head comprising a club head body and a sole mass element are described herein. The club head comprises a center of gravity height measured between a club head center of gravity and at least one keel point. The club head comprises a face surface, wherein the face surface defines a face height. The club head defines a ratio of club head center of gravity height to face height, wherein the ratio is less than or equal to approximately 0.36.

First claim

What is claimed is:

1. A golf club head comprising:
a club head body comprising a front end, a rear end opposite the front end, a top end, and a bottom end opposite the top end, a sole surface; and
a sole mass element configured to be coupled to the club head body, wherein;
the sole surface comprises a sole mass element cavity configured to receive the sole mass element;
the sole mass element is configured to be coupled to the club head body at the sole mass element cavity;
wherein:
the golf club head comprises a club head center of gravity (CG);
the golf club head comprises at least one keel point;

the golf club head defines a top-bottom axis extending between the top end and the bottom end;
the golf club head defines a CG height, the CG height is measured between the club head CG and the at least one keel point in a direction extending parallel to the top-bottom axis;
the front end comprises a face surface;
the face surface defines a face height; and
a ratio of the club head CG height to the face height is less than or equal to approximately 0.36;
wherein the sole mass element comprises a sole mass element mass;
the golf club head comprises a golf club head mass, the golf club head mass comprising the sole mass element mass;
the sole mass element accounts for greater than or equal to approximately 20% of the golf club head mass;

wherein the sole mass element comprises at least one highest element point; and
wherein the golf club head comprises a sole mass element height when the sole mass element is coupled to the club head body;
the sole mass element height is measured between the at least one highest element point and the at least one keel point in a direction extending parallel to the top-bottom axis; and
the sole mass element height is less than or equal to approximately 1.651 centimeters.

2. The golf club head of claim 1 , wherein the face surface comprises a face surface area less than or equal to approximately 30 square centimeters; or the golf club head comprises a volume less than or equal to approximately 300 cubic centimeters.

3. The golf club head of claim 1 , wherein at least one of:
the sole mass element is configured to be adhesively coupled to the club head body; and
the sole mass element is configured to be mechanically coupled to the club head body.

4. The golf club head of claim 1 , wherein the sole mass element comprises an exposed surface; the exposed surface of the sole mass element comprises a surface area.

5. The golf club head of claim 4 , wherein the surface area of the exposed surface is greater than or equal to approximately 15 square centimeters.

6. The golf club head of claim 4 , wherein the surface area of the exposed surface is greater than or equal to approximately 19 square centimeters.

7. The golf club head of claim 1 , wherein:
the golf club head comprises a leading edge, wherein the leading edge comprises at least one leading edge point;
the sole mass element comprises at least one foremost element point;
the golf club head defines a front-rear axis extending between the front end and the rear end;
the golf club head comprises a sole mass element depth when the sole mass element is coupled to the club head body, the sole mass element depth is measured between the at least one leading edge point and the at least one foremost element point in a direction extending parallel to the front-rear axis;
the sole mass element depth is greater than or equal to approximately 0.947 centimeters, and less than or equal to approximately 1.306 centimeters.

8. The golf club head of claim 1 , wherein when the sole mass element is coupled to the club head body, the club head CG height is less than or equal to approximately 1.415 cm.

9. A golf club head comprising:
a club head body comprising a front end, a rear end opposite the front end, a top end, and a bottom end opposite the top end; and
a sole mass element configured to be coupled to the club head body;
wherein:
the golf club head comprises a club head center of gravity (CG);
the golf club head comprises at least one keel point;

the golf club head defines a top-bottom axis extending between the top end and the bottom end;
the golf club head defines a front-rear axis extending between the front end and the rear end;
the golf club head defines a CG height, the CG height is measured between the club head CG and the at least one keel point in a direction extending parallel to the top-bottom axis;
the golf club head comprises a leading edge, wherein the leading edge comprises at least one leading edge point;
the golf club head defines a CG depth, the CG depth is measured between the club head CG and the at least one leading edge point in a direction extending parallel to the front-rear axis;
the club head CG depth is greater than or equal to approximately 3.431 centimeters;

the front end comprises a face surface;
the face surface defines a face height; and
a ratio of the club head CG height to the face height is less than or equal to approximately 0.36.

10. The golf club head of claim 9 , wherein the face surface comprises a face surface area less than or equal to approximately 30 square centimeters; or the golf club head comprises a volume less than or equal to approximately 300 cubic centimeters.

11. The golf club head of claim 9 , wherein at least one of:
the sole mass element is configured to be adhesively coupled to the club head body; and
the sole mass element is configured to be mechanically coupled to the club head body.

12. The golf club head of claim 9 , wherein the sole mass element comprises an exposed surface; the exposed surface of the sole mass element comprises a surface area.

13. The golf club head of claim 12 , wherein the surface area of the exposed surface is greater than or equal to approximately 15 square centimeters.

14. The golf club head of claim 12 , wherein the surface area of the exposed surface is greater than or equal to approximately 19 square centimeters.

15. The golf club head of claim 9 , wherein:
the sole mass element comprises at least one foremost element point;
