Golf club head having complex striking plate structure

Abstract

A golf club head includes a golf club head body and a striking plate connected thereto. The striking plate includes a first plate, a second plate and elastically deformable spaces. The first plate has a front surface to provide a striking surface, and a rear surface to provide a first connecting surface. The second plate has a front surface to provide a second connecting surface, and a rear surface. The first connecting surface of the first plate is attached to the second connecting surface of the second plate to form the striking plate which is connected to a front portion of the golf club head body. The elastically deformable spaces are formed between the first connecting surface of the first plate and the second connecting surface of the second plate.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a golf club head having a complex striking plate structure. Particularly, the present invention relates to the complex striking plate structure of the golf club head formed with multiple metal / nonmetal plates combined together. More particularly, the present invention relates to the complex striking plate structure of the golf club head having elastically deformable spaces provided between two metal / nonmetal plates.[0003]2. Description of the Related Art[0004]A conventional golf club head, as described in Taiwanese Patent Publication No. 550106, entitled “JOINING METHOD FOR GOLF CLUB HEAD,” discloses the following steps:[0005]1. Preparing a first metal plate and a second metal plate made from a first metal and a second metal which are heterogeneous metals;[0006]2. Joining the first metal plate and the second metal plate to form a complex metal plate by explosion welding;[0007]3. Shaping ...

AI Technical Summary

Benefits of technology

[0016]The primary objective of this invention is to provide a golf club head having a complex striking plate structure, wherein a first plate and a second plate are combined to form a striking plate. Elastically deformable spaces are formed between the first plate and the second plate so as to provide a high degree of elastic deformability of the striking plate. Accordingly, the complex striking plate structure can enhance the striking stability of the golf club head.

Problems solved by technology

A number of design limitations exist for such a striking plate due to (1) difficulties in manufacturing, and (2) problematic aspects which naturally occur during use.

The primary problem with the structure of such a striking plate is the difficulty in forming a recessed hole on the second metal plate of the striking plate since it may sophisticate the steps of manufacture, and increase manufacture cost.

With regard to the problematic aspects which naturally occur during use, such a striking plate susceptible to a number of problems, including: (1) loss of the structural strength of the central portion of the striking plate; and (2) weakness of the combined relationship between the two metal plates of the complex striking plate.

The primary problem with the structure of such a striking plate is due to the fact that the central portion (i.e. sweet spot) of the striking plate has a relatively thin thickness.

Although it would be advantage to make the central portion of the striking plate from thinner material with a higher degree of elastic deformability, the thinner first plate of the striking plate is susceptible to distortion or crack in the central portion, after long-term use, due to a greater stress or impact in repeatedly striking a golf ball.

However, the thin central portion of the striking plate has a thickness substantially identical with that of the first metal plate which may weaken the entire strength of the striking plate.

Another problem with the structure of such a striking plate is weakness of the welding portion due to the fact that only the peripheral portion of the second metal plate is combined with the first metal plate.

This may reduce the useful life of the golf club head.
