Connecting structure for a striking plate of a golf club head

Abstract

A golf club head includes a golf club head body, a ring, and a striking plate. The golf club head body includes a recession in a side thereof, the recession including a shoulder on an inner peripheral edge thereof. The ring is mounted on the shoulder of the golf club head body. The striking plate is mounted in the recession of the golf club head body and securely engaged with the ring, with the ring supporting a rear side of the striking plate. The striking plate and the golf club head body have a relatively small contact area therebetween to thereby reduce an amount of the striking stress of the striking plate absorbed by the golf club head body, thereby assuring high deformability of the striking plate.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a connecting structure for connecting a striking plate of a golf club head. In particular, the present invention relates to a connecting structure for connecting a striking plate to a golf club head body. [0003] 2. Description of Related Art [0004]FIGS. 1 and 2 of the drawings illustrate a typical golf club head including a golf club head body 10 and a striking plate 20. The golf club head body 10 includes a recession 11, with a shoulder 12 being formed on an inner peripheral edge of the recession 11 and with a flange 13 being formed on an outer peripheral edge of the recession 11. The striking plate 20 includes a stepped portion 21 on a periphery thereof. When connecting the striking plate 20 to the golf club head body 10, the striking plate 20 is firstly inserted into the recession 11, and a pressing block (not shown) is used to press the flange 13, causing the flange 13 to deform ...

AI Technical Summary

Benefits of technology

[0006] An object of the present invention is to provide a connecting structure for a striking plate of a golf club head that reduces the amount of the striking stress of the striking plate absorbed by the golf club head body is reduced, thereby assuring high deformability of the striking plate. The striking effect of the golf club is thus improved.

[0007] Another object of the present invention is to provide a connecting structure for a striking plate of a golf club head that reduces an amount of the striking stress of the striking plate absorbed by the golf club head body. Vibrations transmitted to the handle of the golf club are reduced, and the gripping comfort is thus improved. SUMMARY OF THE INVENTION

[0009] The striking plate and the golf club head body have a relatively small contact area therebetween to thereby reduce an amount of the striking stress of the striking plate absorbed by the golf club head body, thereby assuring high deformability of the striking plate.

[0012] In another embodiment of the invention, the shoulder of the golf club head includes an annular groove for securely receiving the ring. The annular groove includes a plurality of notches in at least one of two opposed annularly extending corner portions thereof. The notches receive deformed portion of the ring during a pressing procedure, thereby reducing a contact area between the striking plate and the shoulder of the golf club head body.

Problems solved by technology

However, when the golf club head body 10 is made of a material having a greater Young's modulus (e.g., stainless steel or carbon steel having a Young's modulus of 3×107 psi) under the consideration of overall structural strength, the golf club head body 10 having a low deformability and a high damping coefficient absorbs more striking stress, which adversely affects the deformability and striking effect of the striking plat 20.

The gripping comfort and the structural integrity of the golf club are thus adversely affected.
