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.
Claims20
A putter-type golf club head comprising:
- a putter club face defined by a toe end, a heel end, a top rail and a sole;
- and
- a plurality of grooves disposed on the putter club face between the top rail and the sole, each groove of the plurality of grooves extending between the toe end and the heel end and comprising a first horizontal wall, a second horizontal wall, a first vertical wall, and a second vertical wall;
- wherein each groove of the plurality of grooves is horizontally separated into a toe portion proximal the toe end of the putter club face, a heel portion proximal a heel end of the putter club face, and a center portion between the toe portion and the heel portion;
- 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;
- wherein a distance between the first vertical wall and the second vertical wall of each of the plurality of grooves defines a length;
- wherein a depth of each of the plurality of grooves at the heel portion and the toe portion of the groove is shallower than a depth at the center portion of the groove;
- wherein a deepest portion of at least one groove is defined by a generally planar bottom surface portion of the groove;
- wherein the plurality of grooves are separated by a plurality of land portions, and
- a width of the land portions varies in a direction extending between the top rail and the sole, or in a direction extending between the heel end and the toe end.
