Abstract

A golf club head including a club face defined by a toe end, a heel end, a top rail and a sole. The golf club head including a plurality of grooves disposed on the club face between the top rail and the sole. Each groove extends between the toe end and the heel end. Depths of the grooves vary in a direction extending between the top rail and the sole and in a direction extending between the heel end and the toe end. Widths of each of the plurality of grooves vary in a direction extending between the heel end and the toe end.

First claim

What is claimed is:

1 . A golf club head comprising:
a club face defined by a toe end, a heel end, a top rail and a sole; and a plurality of grooves disposed on the club face between the top rail and the sole, each groove extending between the toe end and the heel end and including a first horizontal wall and a second horizontal wall; wherein a distance between the first horizontal wall and the second horizontal wall of each of the plurality of grooves defines a width; wherein the width of each of the plurality of grooves varies in a direction extending between the heel end and the toe end.

2 . The golf club head of claim 1 , wherein lengths of the each of the plurality of grooves vary in a direction between the top rail and the sole.

3 . The golf club head of claim 1 , wherein lengths of the each of the plurality of grooves increase from the top rail to a center of the club face and decrease from the center of the club face to the sole.

4 . The golf club head of claim 1 wherein, depths of the grooves increase in a direction from the sole to the top rail.

5 . The golf club head of claim 1 , wherein depths of the grooves increase in a direction from the top rail to the sole.

6 . The golf club head of claim 1 , further comprising a separate face portion attached to the club face, wherein the grooves are located on the face portion.

7 . A golf club head comprising:
a club face defined by a toe end, a heel end, a top rail and a sole; and a plurality of grooves disposed on the club face between the top rail and the sole, each groove extending between the toe end and the heel end; wherein depths of the grooves vary in a direction extending between the top rail and the sole and in a direction extending between the heel end and the toe end; wherein widths of each of the plurality of grooves vary in a direction extending between the heel end and the toe end.

8 . The golf club head of claim 7 , wherein at least one of a cross sectional configuration of the grooves taken from a section extending from the top rail to the sole or a cross sectional configuration of the grooves taken from a section extending from the heel end to the toe end varies between the top rail and the sole.

9 . The golf club head of claim 7 , wherein the grooves located between a generally center portion of the face and the sole have a greater depth than the grooves located between the center portion and the top rail.

10 . The golf club head of claim 7 , wherein the grooves located between a generally center portion of the face and the top rail have a greater depth than the grooves located between the center portion and the sole.

11 . The golf club head of claim 7 , further comprising a separate face portion attached to the club face, wherein the grooves are located on the face portion.

12 . The golf club head of claim 7 , wherein a deepest portion of at least one groove is defined by a generally planar bottom surface portion of the groove.

13 . The golf club head of claim 7 , wherein lengths of the each of the plurality of grooves vary in a direction between the top rail and the sole.

14 . The golf club head of claim 7 , wherein lengths of the each of the plurality of grooves increase from the top rail to a center of the club face and decrease from the center of the club face to the sole.

15 . A golf club head comprising:
a club face defined by a toe end, a heel end, a top rail and a sole; a plurality of grooves disposed on the club face between the top rail and the sole, each groove extending between the toe end and the heel end and including:
a bottom surface, a depth defined between the club face and the bottom surface,
a first vertical wall,
a second vertical wall opposite the first vertical wall, a length defined between the first vertical wall to the second vertical wall,
a first horizontal wall, and
a second horizontal wall, a width defined between the first horizontal wall and the second horizontal wall,
wherein the widths of each of the plurality of grooves vary along the length.

16 . The golf club head of claim 15 , wherein the depths of each of the plurality of grooves vary along the length.

17 . The golf club head of claim 15 , wherein the lengths of the each of the plurality of grooves vary in a direction between the top rail and the sole.

18 . The golf club head of claim 15 , wherein the lengths of the each of the plurality of grooves increase from the top rail to a center of the club face and decrease from the center of the club face to the sole.

19 . The golf club head of claim 15 , wherein the widths of each of the plurality of grooves increases from the first vertical wall to a center of the club face and decrease from the center of the club face to the second vertical wall.
