(a) Technical Field of the Invention
The present invention relates to a golf club head, and in particular to a golf club head having lowered gravity center to enhance striking stability and performance of playing golf.
(b) Description of the Prior Art
Golf has been a very popular sports game for social relationship between people can be improved during the driving from one hole to another hole in the golf field. To have an excellent performance of playing golf, practice is the most important way. However, good and appropriate golf clubs also play an important role in playing the game. For different striking, different clubs may be selected. For example, for long distance driving, a wooden club is used. For a currently available wooden club, a club head is often made of metals or composite materials.
The primary purpose of the present invention is to provide a golf club head, which, without adversely affecting the structural strength of a golf club head, enhances the efficiency of manufacturing of the golf club head, shortening the manufacturing time, and also lowers the gravity center of the golf club head to enhance striking stability and performance of golf playing.
To achieve the above objective, in accordance with the present invention, a golf club head is provided, comprising a three-piece construction, of which a front piece and a rear piece are made of metal, while an intermediate piece is made of fiber-reinforced plastic, composite material or metal. The intermediate piece is jointed to the front and rear pieces by means of adhesives or welding. Bolts are provided in a lower portion of the rear piece to threadingly engage the front piece to securely fix all the pieces together to form the golf club head, which has a lowered gravity center and enhanced striking stability.
The foregoing object and summary provide only a brief introduction to the present invention. To fully appreciate these and other objects of the present invention as well as the invention itself, all of which will become apparent to those skilled in the art, the following detailed description of the invention and the claims should be read in conjunction with the accompanying drawings. Throughout the specification and drawings identical reference numerals refer to identical or similar parts.
Many other advantages and features of the present invention will become manifest to those versed in the art upon making reference to the detailed description and the accompanying sheets of drawings in which a preferred structural embodiment incorporating the principles of the present invention is shown by way of illustrative example.
The following descriptions are of exemplary embodiments only, and are not intended to limit the scope, applicability or configuration of the invention in any way. Rather, the following description provides a convenient illustration for implementing exemplary embodiments of the invention. Various changes to the described embodiments may be made in the function and arrangement of the elements described without departing from the scope of the invention as set forth in the appended claims.
With reference to the drawings and in particular to
In a preferred embodiment of the present invention, the golf club head of the present invention is of a three-piece structure with front and rear pieces being made of metal and intermediate piece of composite material, which are jointed together by means of adhesives and further secured by bolts. In this way, as compared to the conventional technology of simply welding, the manufacturing process has reduced steps and the manufacturing time is shortened. Further, both application of adhesives and tightening of bolts can be easily done by any operator who is not an experienced or skilled operator. The flaw rate of product can be effectively lowered to further reduce the manufacturing costs and enhance market competitively. Further, arranging the bolts 31 in the lower portion to enhance the fixing or securing force can also realize lowering of the overall gravity center of the golf club head, which leads to stability of ball hitting and enhance the performance of playing golf.
Referring now to
The manufacturing process of the golf club head, as compared to the conventional technology of simply welding, can be carried out with reduced steps and the manufacturing time is shortened. Further, both application of adhesives and tightening of bolts can be easily done by any operator who is not an experienced or skilled operator. The flaw rate of product can be effectively lowered to further reduce the manufacturing costs and enhance market competitively. Further, using the bolts 61 to enhance the fixing or securing force can also lower the overall gravity center of the golf club head, which leads to stability of ball hitting and enhances the performance of playing golf.
It will be understood that each of the elements described above, or two or more together may also find a useful application in other types of methods differing from the type described above.
While certain novel features of this invention have been shown and described and are pointed out in the annexed claim, it is not intended to be limited to the details above, since it will be understood that various omissions, modifications, substitutions and changes in the forms and details of the device illustrated and in its operation can be made by those skilled in the art without departing in any way from the spirit of the present invention.
