Benefits of technology

The present invention provides a new solution for increasing the backspin of golf balls using high lofted golf clubs. This is achieved by increasing the number of sharp edges that contact the golf ball during impact. The sharp edges slice through debris and better grasp the soft cover of the golf ball, resulting in higher effective coefficients of friction between the two surfaces. The effective coefficient of friction is primarily determined by the number of edges that contact the ball and the sharpness of the edges. The invention maximizes the number of grooves in contact with the ball during impact, which leads to more backspin. The patent describes different aspects of the invention, including iron-type golf club heads with a body having a face and various sets of grooves. The technical effects of the invention include increased backspin, improved ball control, and better overall performance of the golf club.

Problems solved by technology

This leads to higher effective coefficients of friction for the golf club which in turn leads to more backspin.

Embodiment Construction

[0044]As shown in FIG. 1-7, an iron-type golf club is generally designated 20. The golf club head 20 also has a top portion 46, a sole portion 48, a heel portion 50, a toe portion 52 and a rear surface 54. The top wall 46 extends rearward from the top end of the front surface 23. The golf club head 20 includes a body 21 having a face 22 with a surface 23 and a plurality of grooves 25. The body 21 is preferably composed of a material such as titanium materials, stainless steel, carpenter steel, 1020 steel, amorphous metals and the like. The material of the body 21 preferably has a density between 4 g / cm3 and 10 g / cm3. Such titanium materials include pure titanium and titanium alloys such as 6-4 titanium alloy, 6-22-22 titanium alloy, 4-2 titanium alloy, SP-700 titanium alloy (available from Nippon Steel of Tokyo, Japan), DAT 55G titanium alloy available from Diado Steel of Tokyo, Japan, Ti 10-2-3 Beta-C titanium alloy available from RTI International Metals of Ohio, and the like.

Abstract

The present invention discloses a golf club head having a plurality of grooves. On the face of the golf club head is a first and second plurality of grooves. The second set of plurality of grooves is smaller in width and depth than those of the first set of plurality of grooves.

Description

CROSS REFERENCES TO RELATED APPLICATIONS[0001]The present application claims priority to U.S. Provisional Patent Application No. 61 / 260,666, filed on Nov. 12, 2009, which is hereby incorporated by reference in its entirety.STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT[0002]Not ApplicableBACKGROUND OF THE INVENTION[0003]1. Field of the Invention[0004]The present invention relates to a golf club head. More specifically, the present invention relates to a golf club head having a plurality of grooves.[0005]2. Description of the Related Art[0006]The prior art discloses various methods to manufacture golf club heads, especially iron-type golf club heads. For example, Rogers, U.S. Pat. No. 4,027,885 for Golf Iron Manufacture, discloses scoring grooves into a face for the club head.[0007]Taylor, U.S. Pat. No. 4,077,632 for a Lined Face For A Golf Club discloses grooves in compliance with the Rules of Golf at that time.[0008]Ribaudo, U.S. Pat. No. 4,529,203, for Golf Club d...
