Abstract

Embodiments of grooves of golf club heads and methods to manufacture grooves of golf club heads are generally described herein. Other embodiments may be described and claimed.

First claim

What is claimed is:

1. A golf club head comprising:
a body portion having a body central region, a body toe portion, a body heel portion, a body top rail portion and a body sole portion;
a club face on the body portion comprising grooves extending from a center portion of the club face toward the body heel portion and from the center portion of the club face toward the body toe portion, each groove having a depth portion defining a largest depth of the groove, the depth portion having a length extending in a direction from the body heel portion to the body toe portion;
wherein the depth portions of at least a plurality of the grooves have a greater length between the center portion of the club face and the body toe portion than between the center portion of the club face and the body heel portion;
wherein a depth of each groove increases from the groove heel portion to the depth portion;
wherein a depth of each groove increases from the groove toe portion to the depth portion;
wherein the lengths of the depth portions of at least two of the grooves located between the body top rail portion and the body central region increase in a direction from the body top rail to the central region; and
wherein the lengths of the depth portions of at least two of the grooves located between the body sole portion and the body central region increase in a direction from the body sole portion to the central region.

2. The golf club head of claim 1 , wherein the lengths of the depth portions of the plurality of the grooves are configured based on a stroke type of an individual.

3. The golf club head of claim 1 , wherein an increase in the lengths of the depth portions of the plurality of the grooves is proportional to an increase in an amount of arc in a putting stroke of an individual.

4. The golf club head of claim 1 , wherein cross sectional configurations of at least two of the grooves vary between at least one of the body heel portion and the body toe portion or the body top rail portion and the body sole portion.

5. The golf club head of claim 1 , wherein the club face is detachably attached to the body portion.

6. The golf club head of claim 1 , wherein the club face is defined by a top rail portion, a sole portion and a mid portion between the top rail portion and the sole portion, wherein the plurality of the grooves are generally disposed in the mid portion, and wherein the remaining grooves are disposed in the top rail portion and the sole portion.

7. The golf club head of claim 1 , wherein the grooves increase in depth in a direction from the body top rail portion toward the center portion and in a direction from the body sole portion toward the center portion.

8. A method of manufacturing a golf club head comprising:
forming a body portion having a body central region, a body toe portion, a body heel portion, a body top rail portion and a body sole portion;
forming a club face on the body portion comprising grooves extending from a center portion of the club face toward the body heel portion and from the center portion of the club face toward the body toe portion, each groove having a depth portion defining a largest depth of the groove, the depth portion having a length extending in a direction from the body heel portion to the body toe portion;
wherein the depth portions of at least a plurality of the grooves have a greater length between the center portion of the club face and the body toe portion than between the center portion of the club face and the body heel portion;
wherein a depth of each groove increases from the groove heel portion to the depth portion;
wherein a depth of each groove increases from the groove toe portion to the depth portion;
wherein the lengths of the depth portions of at least two of the grooves located between the body top rail portion and the body central region increase in a direction from the body top rail to the central region; and
wherein the lengths of the depth portions of at least two of the grooves located between the body sole portion and the body central region increase in a direction from the body sole portion to the central region.

9. The method of claim 8 , wherein the lengths of the depth portions of the plurality of the grooves are configured based on a stroke type of an individual.

10. The method of claim 8 , wherein an increase in the lengths of the depth portions of the plurality of the grooves is proportional to an increase in an amount of arc in a putting stroke of an individual.

11. The method of claim 8 comprising forming the club face such that cross sectional configurations of at least two of the grooves vary between at least one of the body heel portion and the body toe portion or the body top rail portion and the body sole portion.

12. The method of claim 8 comprising forming the body portion and the club face such that the club face is detachably attached to the body portion.

13. The method of claim 8 , wherein the club face is defined by a top rail portion, a sole portion and a mid portion between the top rail portion and the sole portion, wherein the plurality of the grooves are generally disposed in the mid portion, and wherein the remaining grooves are disposed in the top rail portion and the sole portion.

14. A golf club head comprising:
a body portion having a body central region, a body toe portion, a body heel portion, a body top rail portion and a body sole portion;
a first club face configured to be attachable to the body and comprising first grooves extending from a first center portion of the first club face toward the body heel portion and from the first center portion of the first club face toward the body toe portion, each of the first grooves having a first depth portion defining a largest depth of the first grooves and having a first length extending from the first center portion of the first club face toward the body toe portion, the first length being associated with a first type of putting stroke,
wherein a depth of each first groove increases from the first groove heel portion to the first depth portion;
wherein a depth of each first groove increases from the first groove toe portion to the first depth portion;
wherein the first lengths of the first depth portions of at least two of the first grooves located between the body top rail portion and the body central region increase in a direction from the body top rail to the central region; and
wherein the first lengths of the first depth portions of at least two of the first grooves located between the body sole portion and the body central region increase in a direction from the body sole portion to the central region; and
a second club face configured to be attachable to the body and comprising second grooves extending from a second center portion of the second club face toward the body heel portion and from the second center portion of the second club face toward the body toe portion, each of the second grooves having a second depth portion defining a largest depth of the second grooves and having a second length extending from the second center portion of the second club face toward the body toe portion,
wherein a depth of each second groove increases from the second groove heel portion to the second depth portion;
wherein a depth of each second groove increases from the second groove toe portion to the second depth portion;
wherein the second lengths of the second depth portions of at least two of the second grooves located between the body top rail portion and the body central region increase in a direction from the body top rail to the central region; and
wherein the second lengths of th
