Claims
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
[0001] 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
[0002] 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.
[0003] 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.
[0004] 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
[0005] 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.
[0006] 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
[0007] FIG. 1 shows the golf club head of the present
invention;
[0008] FIG. 2 shows that the identification pattern is hidden when
viewed perpendicularly to the striking surface;
[0009] FIG. 3 shows that the identification pattern is visible when
viewed from an angle to the striking surface;
[0010] FIG. 4 shows a first example of a conventional golf club
head;
[0011] FIG. 5 shows a second example of a conventional golf club
head, and
[0012] FIG. 6 shows a third example of a conventional golf club
head.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0013] 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.
[0014] 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.
[0015] 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.
[0016] 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.
