Golf club head counterweight structure able to absorb shock

Abstract

A shock-damping counterweight structure for golf club head is composed of a main head body with a batting plate and a recess behind said batting plate, at least one elastic cushion consisting of a bagand an air chamber, and a counterweight. Said elastic cushion and counterweight are arranged in said recess on main head body.

Description

technical field [0001] The present invention relates to a shock-absorbing golf club head counterweight structure, in particular to a club head body using an elastic air cushion to absorb the aftershock of hitting a ball and a counterweight block to adjust the overall center of gravity. Background technique [0002] For shock-absorbing structures of existing golf club heads, please refer to figure 1 The shown US Patent No. 5,290,036 "Cavity Back Iron with Vibration Dampening Material in Rear Cavity" includes a club head body 100 and a shock-absorbing material 200 . The club head body 100 is provided with a striking panel 101 and a back hole 102 . The hitting panel 101 is used to hit a golf ball. The cavity 102 is used for filling the shock-absorbing material 200 . The shock-absorbing material 200 is preferably selected from materials with a shore D hardness between 20 and 50, such as polyurethane [polyurethane, PU], foam material [foam] or rubber. Thereby, when the ball i...

AI Technical Summary

Problems solved by technology

However, the combined structure formed by the counterweight and the club head body by the above method usually has too little damping and poor shock absorption

Under the long-term impact vibration of the club head body, the joint structure between the weight and the club head body is prone to cracking or loosening, which may not only produce abnormal sound when hitting the ball, but even cause the weight to fall off
