Variable scoreline golf club groove configuration

Abstract

The golf club uses specific type grooves specialized for individual types of known golf clubs, wherein the modified grooves maximizes control of the golf ball through tailoring backspin to the club selected. Clubs 1, 2, 3, 4, 5, 6, and 7 wherein selected club configuration has a reduced groove volume to maximize performance. Clubs 8, 9, pitching wedge, gap wedge and sand wedge has an increased groove volume to maximize performance.

Description

CROSS REFERENCE TO RELATED APPLICATIONS [0001] A claim of benefit is made to U. S. Ser. No. 60 / 442,248 filed on Jan. 24, 2003, the contents are incorporated by reference in their entirety.BACKGROUND OF THE INVENTION [0002] The present invention relates to the grooves formed across the club face of golf clubs including irons, drivers, woods and particularly wedges. [0003] Golf club wedges are usually designed with varying degrees of loft generally ranging from a minimum of about 48 degrees to a maximum of about 64 degrees. The varying degrees of loft help to control the trajectory and distance a golf ball will travel. [0004] In play, especially with the higher numbered irons and wedges, control is obtained in part by means of backspin. At the time of impact, the golf ball is contacted against the club face with substantial deformation. Control of the ball in flight is partly exercised by backspin, and more control is obtained on the initial bounce (i.e., the ball will “bite” or hold ...

AI Technical Summary

Benefits of technology

[0007] The invention produces a set of golf clubs that are optimized in performance while minimizing golf ball cover damage. It has been discovered that a set of clubs is optimized for playing performance when a club configuration selected from the group consisting of clubs 1, 2, 3, 4, 5, 6, and 7 have a reduced volume groove such as a “V” shaped grooves and / or a groove configuration or modification that produces less spin, which is desirable for shots using those clubs. A club configuration selected from the group consisting of 8, 9, pitching wedge, gap wedge and sand wedge is optimized in the club set when it has an increased volume groove configuration such as “U” shaped grooves and / or a modified configuration or similar type grooves for greens shots.

Problems solved by technology

Having all grooves identical is a performance compromise that prior art golf club manufacturers were previously unaware of because the V-shape groove is not suited for all clubs in a set to maximize performance.

The square shaped groove however also has many deficiencies, the largest being the cuts and shear produced on the cover of a golf ball leading to premature failure of a golf ball.
