Putter face groove pattern for improved feel, accuracy and distance control

This application claims the benefit of provisional patent application Ser. No. 60/998,344 Oct. 10, 2007 by the present inventor.

1. Field of Invention

This invention relates to golf club putters, specifically to an improved putter ball striking face.

2. Prior Art

The present invention relates to golf putters and in particular to putters with improved ball striking face configurations.

It is well known that a golf ball tends to skid a considerable distance across a putting green surface after being struck by a planar ball striking face of a putter before it begins to roll. Various ball striking face surfaces, many with face inserts made of different materials, have been developed to improve the how quickly a golf ball rolls off a putter face after being struck.

For example, U.S. Pat. No. 6,257,994 to Antonious uses a series of geometric shapes distributed across the face of a putter to increase roll.

U.S. Pat. No. 5,709,616 to Rife uses a series of horizontal, V-shaped grooves with truncated outer ball gripping edges to grip a ball as it leaves the striking face to increase roll.

U.S. Pat. No. 5,637,044 to Swash shows a golf putter having a ball striking face with a plurality of concentric grooves.

U.S. Pat. No. 4,964,641 to Miesch, et al. shows a putter face made of an array of pyramids to increase friction between the golf ball and putter face.

U.S. Design Pat. No. D 411,275 to Bottema et al. shows a putter face with an array of cylindrical projections.

U.S. Design Pat. No. D 415,809 to Bottema et al. shows a putter face with an array of cubed shaped projections.

U.S. Design Pat. No. D 57,980 to Kraeueter shows a putter face with an array of diamond shaped projections.

U.S. Pat. No. 6,007,434 to Baker et al. shows a putter face with an array of truncated, pyramid shaped projections.

U.S. Pat. No. 4,508,342 to Drake both show a putter face with uniformly spaced vertical grooves.

U.S. Design Pat. No. D 335,694 to Stuff et al. Shows a putter face with slanted grooves.

U.S. Design Pat. No. D 63,284 to Challis shows a putter face with an array of square projections.

The present invention relates to a putter ball striking face configuration which uses vertical grooves with combinations of various widths, spacing and depths.
