Striking plate for a golf club head
A striking plate of a golf club head includes a plate body, a plurality of parallel elongate grooves formed in a surface of the plate body and each having a groove bottom, and a plurality of protrusions projecting from the groove bottom of each of the grooves and spaced apart from each other along the groove bottom.
1. Field of the Invention
The invention relates to a striking plate for a golf club head, more particularly to a striking plate for a golf club head having an increased friction coefficient.
2. Description of the Related Art
Referring to
It is desirable in the art to further increase the friction coefficient of the striking plate 12 so as to further improve the direction controllability of the striking plate 12.
SUMMARY OF THE INVENTIONTherefore, the object of the present invention is to provide a striking plate for a golf club head which is increased in its friction coefficient.
Accordingly, a striking plate of a golf club head of this invention includes a plate body, a plurality of parallel elongate grooves formed in a surface of the plate body and each having a groove bottom, and a plurality of protrusions projecting from the groove bottom of each of the grooves and spaced apart from each other along the groove bottom.
Other features and advantages of the present invention will become apparent in the following detailed description of the preferred embodiments with reference to the accompanying drawings, of which:
Before the present invention is described in greater detail, it should be noted that like elements are denoted by the same reference numerals throughout the disclosure.
Referring to
In view of the aforesaid, since the friction coefficient of the striking surface of the striking plate 22 can be increased by providing the protrusions 223 in the first grooves 222 of the striking plate 22, the direction controllability of the striking plate 221 can be improved.
Referring to
Specifically referring to
The protrusions 223 can be formed by laser engraving or by using an engraving machine for preliminary engraving followed by laser engraving for refining engraving.
Referring to
Referring to
While the present invention has been described in connection with what are considered the most practical and preferred embodiments, it is understood that this invention is not limited to the disclosed embodiments but is intended to cover various arrangements included within the spirit and scope of the broadest interpretation so as to encompass all such modifications and equivalent arrangements.
Claims
1. A striking plate for a golf club head, comprising:
- a plate body;
- a plurality of parallel elongate first grooves formed in a surface of said plate body and each having a groove bottom; and
- a plurality of protrusions projecting from said groove bottom of each of said first grooves and spaced apart from each other along said groove bottom.
2. The striking plate as claimed in claim 1, wherein each of said first grooves has a depth larger than a height of each of said protrusions.
3. The striking plate as claimed in claim 1, wherein each of said first grooves further has two opposite groove walls, said groove bottom bridging said groove walls, each of said groove walls having a stepped surface.
4. The striking plate as claimed in claim 1, further comprising at least an elongate second groove formed between two adjacent ones of said first grooves and having a depth smaller than that of said first grooves.
5. The striking plate as claimed in claim 4, wherein said second groove has a width smaller than that of said first grooves.
6. The striking plate as claimed in claim 1, wherein said protrusions are arranged in a row along each of said first grooves.
7. The striking plate as claimed in claim 1, wherein each of said protrusions has a substantially rectangular cross section.
8. The striking plate as claimed in claim 1, wherein each of said protrusions has a substantially circular cross section.
9. The striking plate as claimed in claim 1, wherein each of said protrusions has an oval cross section.
10. The striking plate as claimed in claim 1, wherein each of said protrusions has a substantially X-shaped cross section.
11. The striking plate as claimed in claim 1, wherein each of said protrusions tapers upwardly from said groove bottom of a corresponding one of said first grooves.
12. The striking plate as claimed in claim 1, wherein said protrusions are arranged in two rows along each of said first grooves.
13. The striking plate as claimed in claim 12, wherein said protrusions in one of said two rows are staggered relative to said protrusions in the other one of said two rows.
