Golf club with a striking face having improved characteristic time values

Abstract

A ball striking face for a golf driver, fairway wood and hybrid type golf club head having a central impact area with a average thickness and additional multiple distinct areas outside the central impact area with other average face thicknesses for the improved transfer of energy to a golf ball for additional distance without any additional effort by the golfer. The striking face provides a transfer of energy at the central impact area which does not exceed CT values of 257 u sec. and an improved transfer of energy in one or more areas outside the central impact area that provides CT values greater than 257 u sec. but not greater than 275 u sec. when tested with the United States Golf Association's CT test protocol.

Description

BACKGROUND OF THE INVENTION[0001]The present invention relates to golf clubs and in particular to drivers, fairway woods and hybrids having an improved club head, striking face configuration.[0002]The Characteristic Time, hereinafter CT, has been commonly known as measuring the “spring-like” or “trampoline” effect of a driver, fairway wood or hybrid face or more formally as a measurement of the Coefficient of Restitution of those faces. The CT is recognized in terms of micro seconds and will be referred to hereinafter as u sec.[0003]A wide variety of club head configurations, weighting structures, and striking face features have been proposed and presented to the golfing marketplace to achieve increased performance with these clubs.[0004]However, the focus on increasing the spring-like or trampoline effect for the club face has been in terms of making the center or near center of the face having the highest CT. This is because tour professionals hit the center or very near center of...

AI Technical Summary

Benefits of technology

This patent describes a golf club design that reduces energy loss when a golf ball is struck. This is achieved by creating areas of different thicknesses and shapes that are located both inside and outside of the impact area. These areas are also designed to have a uniform average thickness, which ensures a consistent outcome when using different shapes. Overall, this design helps to maintain the energy of the golf ball and improve its accuracy.

Problems solved by technology

One of the USGA rules relating to equipment limits the transfer of energy to a golf ball due to the spring-like or trampoline effect of the striking face of a golf club.
