Claims:
What is claimed is:

1. A golf club head comprising: a striking surface including a toe area and striking area, the toe area including cruciform patterns and the striking area including parallel grooves and at least one pattern made by electro-etching.

2. The golf club head as claimed in claim 1 further comprising an identification pattern made by electro-etching is defined in the striking area.

Description:

FIELD OF THE INVENTION

The present invention relates to a striking surface of a golf club head and the surface is made with grooves in the surface by way of electro-etching.

BACKGROUND OF THE INVENTION

A conventional golf club head 2 is disclosed in FIG. 4, and generally includes a striking surface 20 which is polished first and then processed by way of sand blasting to form a rough surface so as to increase the ball-controlling coefficient. Nevertheless, the rough surface on the surface 20 does not last long. FIG. 5 shows that golf club head 3 can also be made by CNC and the striking surface 30 thereof is then electro-plated with a coating material and processed by heat treatment. This type of striking surface 30 is slippery for the golf ball which cannot be handled properly. FIG. 6 shows that the golf club head 4 is polished and the striking surface 40 is processed by way of chemical-etching, electroplating and heat treatment. However, the chemical-etching results rough surface that is awkward in appearance and cannot make grooves in the striking surface 40.

All of the above mentioned methods for making the golf club heads require at least two times of machining processes and electro-plating and chemical-etching damage the environment.

The present invention intends to provide a striking surface of a golf club head wherein the striking surface is proceeded with electro-etching process to obtain grooves in the striking surface and an identification pattern can be made in the striking surface.

SUMMARY OF THE INVENTION

The present invention relates to a golf club head that comprises a striking surface including a toe area and striking area. The toe area includes cruciform patterns and the striking area includes parallel grooves and at least one pattern made by electro-etching.

The present invention will become more obvious from the following description when taken in connection with the accompanying drawings which show, for purposes of illustration only, a preferred embodiment in accordance with the present invention.

BRIEF DESCRIPTION OF THE DRAWINGS

FIG. 1 shows the golf club head of the present invention;

FIG. 2 shows that the identification pattern is hidden when viewed perpendicularly to the striking surface;

FIG. 3 shows that the identification pattern is visible when viewed from an angle to the striking surface;

FIG. 4 shows a first example of a conventional golf club head;

FIG. 5 shows a second example of a conventional golf club head, and

FIG. 6 shows a third example of a conventional golf club head.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to FIG. 1, the golf club head 1 of the present invention comprises a striking surface 10 composed of a toe area 11 and striking area 12. The toe area 11 includes cruciform patterns 111 made by CNC and the striking area 12 includes parallel grooves 13 and at least one pattern 121 made by electro-etching. An identification pattern 122 such as a logo made by electro-etching is defined in the striking area 12.

As shown in FIGS. 2 and 3, the identification pattern 122 is hidden when viewed perpendicularly to the striking surface and is visible when viewed from an angle to the striking surface 10.

The golf club head 1 requires only one time of machining process such that the manufacturing cost is less than that of the conventional golf club heads. The striking surface 10 made by way of electro-etching provides a non-slippery surface and the golf ball can be delivered to a far distance. The post-rotation of the golf ball is satisfied. The identification pattern 122 gives the golf club head 1 a unique character and is located at the same plane with the grooves 13. The grooves 13 and the patterns made by electro-etching last long and easily control the golf balls.

While we have shown and described the embodiment in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
