Golf club head for controlling launch velocity of a ball
First Claim
1. A golf club head comprisinga stopper plate disposed at a front end of said golf club head,a trampoline plate for impacting a golf ball disposed a predetermined distance forwardly of said stopper plate, said trampoline plate deflecting in a direction toward said stopper plate and rebounding in a direction away from said stopper plate when said trampoline plate impacts the golf ball, and said stopper plate arresting deflection of said trampoline plate;
- said trampoline plate (a) deflecting toward said stopper plate, free of being arrested by said stopper plate, when impacting the golf ball at a velocity less than 160 ft/sec, and (b) being arrested by said stopper plate, when impacting the golf ball at a velocity greater than 160 ft/sec, andsaid predetermined distance substantially equal to a deflection distance of said trampoline plate, andsaid deflection distance determined by said trampoline plate impacting the golf ball at the velocity of 160 ft/sec, when the trampoline plate is free of being arrested by said stopper plate.

Abstract
A golf club head having a stopper plate disposed at a front end and a trampoline plate disposed forwardly of the stopper plate. The trampoline plate deflects in a direction toward the stopper plate and rebounds in a direction away from the stopper plate when striking a golf ball. The stopper plate is disposed at a predetermined distance from the trampoline plate for arresting a predetermined deflection of the trampoline plate.

10. A golf club head having a front end forming a face comprising
a trampoline plate disposed forwardly of said front end and forming a gap of a predetermined distance between said trampoline plate and said front end, said trampoline plate deflecting in a direction toward said front end and rebounding in a direction away from said front end when striking a golf ball said trampoline plate (a) deflecting, toward said front end, free of being arrested by said front end, when impacting the golf ball at a velocity less than 160 ft/sec, and (b) being arrested by said front end, when impacting the golf ball at a velocity greater than 160 ft/sec; - and
said predetermined distance substantially equal to a deflection distance of said trampoline plate, and said deflection distance determined by said trampoline plate impacting the golf ball at the velocity of 160 ft/sec, when said trampoline plate is free of being arrested by said front end. - View Dependent Claims (11, 12, 13, 14, 15, 16)

17. A method of controlling launch velocity of a golf ball when struck by a golf club head comprising the steps of:
-
a) forming a rigid surface at a front end of the golf club head, b) forwardly spacing a plate at a predetermined distance from the rigid surface, wherein the plate deflects in a direction toward the rigid surface and then rebounds in a direction away from the rigid surface when striking the golf ball; c) measuring a deflection distance of the plate by striking the golf ball at an impact velocity of 160 ft/sec, when the plate is free of touching the rigid surface; and d) spacing the plate at the predetermined distance substantially equal to the measured deflection distance. - View Dependent Claims (18)
