Benefits of technology

[0044]According to an aspect of the present invention, since the striking plate of the present invention has the low-elastic-modulus region and the COR of the low-elastic-modulus regions is relatively higher, and therefore the striking plate of the present invention has a comparatively larger high-COR region. Furthermore, without degrading the durability of the plate body, the low-elastic-modulus region in the plate body is formed by means of heating, melting and annealing the low-elastic-modulus material, and therefore the high-COR region of the striking plate can be effectively enlarged.

Problems solved by technology

However, such a conventional design may reduce the durability of the striking plate, and the striking plate may get damaged after a long time of striking as the thickness is reduced.
How to simply and effectively promote the striking restitution capability without degrading the durability of a striking plate has become an important issue.

first embodiment

The First Embodiment

[0053]FIG. 1 is a schematic 3D exploded view of a golf club head according to a first embodiment of the present invention. Referring to FIG. 1, the golf club head 200 includes a head body 210 and a striking plate 220. The head body 210 has an opening 212, and the striking plate 220 is disposed at the opening 212. The head body 210 and the striking plate 220 form the golf club head 200. In the embodiment, the head body 210 may be a shell, and integrally formed by a common metal material (e.g., stainless steel) by way of lost-wax casing.

[0054]Obviously, the head body 210 in other embodiments of the present invention may also be made of a composite material of metal and a macromolecule plastic material or a high-strength fiber material (for example, carbon fiber) and fabricated by the following steps. For example, a crown (not shown) is independently made by injection molding or thermal compression molding in advance. Then, the crown is embedded into another part of...

second embodiment

The Second Embodiment

[0066]FIG. 5 is a schematic side view of a striking plate according to a second embodiment of the present invention. The major difference between the striking plate 320 in the second embodiment and the striking plate 220 in the first embodiment is that the striking plate 320 of the second embodiment has no cavities 224a. The low-elastic-modulus regions 326 are disposed in the plate body 324 by a penetrating process. The depth D′ of each low-elastic-modulus region 326 may be smaller than 2 mm.

[0067]FIGS. 6A to 6D are schematic flowcharts illustrating the process of fabricating the striking plate in FIG. 5. First, referring to FIG. 6A, a plate body 324 with a first surface 324b is provided. Next, referring to FIG. 6B, a low-elastic-modulus material M is disposed on at least a part of the first surface 324b.

[0068]Next, referring to FIG. 6C, the low-elastic-modulus material M is heated and melted by irradiating the low-elastic-modulus material M with, for example, ...

Abstract

A golf club head including a head body and a striking plate is provided. The head body has an opening. The striking plate having a striking surface includes a plate body and at least a low-elastic-modulus region. The plate body disposed at the opening has a first surface exposed to the outside. The low-elastic-modulus region disposed in the plate body has a second surface exposed to the outside. The striking surface is composed of the first surface and the second surface. The elastic modulus of the low-elastic-modulus region is smaller than that of the plate body. A method of fabricating a striking plate is also provided.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims the priority benefit of Taiwan application serial no. 95141128, filed Nov. 7, 2006. All disclosure of the Taiwan application is incorporated herein by reference.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention generally relates to a golf club head and a method of fabricating a striking plate, and more particular, to a golf club head with a striking plate having a low-elastic-modulus region and a method of fabricating the striking plate.[0004]2.
