Embodiment Construction

[0043] The present invention relates to a golf club head with a blade that is thin and has a high rebound coefficient, so that a golf ball hit by the golf club head of the present invention can fly farther. The coefficient of rebound ("COR") is calculated by the following formula:

[0044] e=(v2-v1) / (U1-U2)

[0045] Among them, U1 is the speed of the club head before the collision; U2 is the speed of the golf ball before the collision, which is 0; v1 is the speed of the club head immediately after the golf ball is separated from the surface of the club head; v2 is the surface of the golf ball and the club head The speed of the golf ball immediately after separation; e is the rebound coefficient between the golf ball and the club surface.

[0046] For systems without additional energy, the value of e is limited to 0 to 1.0. For materials such as soft soil or putty, the coefficient of resilience e is close to 0, while for fully elastic materials whose deformation does not cause ener...

Abstract

A golf club (40) having a club head (42) with a striking plate (72) having a thickness in the range of 0.010 to 0.250 inch is disclosed herein. The club head (42) may be composed of three pieces, a face (60), a sole (64) and a crown (64). Each of the pieces (60, 62 and 64) may be composed of a titanium material. The striking plate (72) of the club head (42) may have an aspect ratio less than 1.7. The striking plate (72) may also have concentric regions of thickness with the thickness portion in the center. The club head (42) may be composed of a titanium material, have a volume in the range of 175 cubic centimeters to 400 cubic centimeters, a weight in the range of 165 grams to 300 grams, and a striking plate (72) surface area in the range of 4.00 square inches to 7.50 square inches. The golf club head (42) may also have a coefficient of restitution greater than 0.8 under test conditions such as the USGA test conditions specified pursuant to Rule 4-1e, Appendix II, of the Rules of Golf for 1998-1999.

Description

Technical field [0001] The present invention relates to a golf club head whose surface is made of forged materials, and particularly relates to a golf club head whose surface is made of thin forged materials so as to transmit energy to the golf ball more effectively when hitting the ball. Background technique [0002] When a golf club head hits a golf ball, the surface of the club head and the golf ball are greatly impacted. Most of the energy is transferred from the club head to the golf ball, but some energy is lost due to the collision. Golf balls generally consist of a surface layer of polymeric material (such as ionomer) enclosing a rubber core. These softer polymer materials with cushioning (energy-absorbing) properties will undergo compression deformation, and the cushioning properties determined by the compression deformation rate are 10 to 100 times greater than the cushioning properties of the metal surface of the club. Therefore, when hitting the ball, unlike the small...
