(b) Description of the Prior Art
With the progress of the modem industrial and commercial society, people are persistently taking every greater living and economic pressure. This makes the modem working longer than ever, and the time they can have for leisure activity and tours is getting less. Various ways are taken by the modem people to releasing their metal and physical strains. A lot of people take their favorite sports or trips in their leisure hours. Some the sports are exciting ones, but the other are smooth and gentle activities. Among all the sports, golf is prevailing in modem urban people for the golf game is not just a sport that helps exercising physical health, but also a way of establishing and enhancing social relationship with other people by friendly conversation in the long course of a golf game. For a golf player, except skill, a golf club, especially the club head, is also of importance for playing a good game. Thus, every manufacturer is devoted themselves in the development of good club and club head. One of the golf club head is made of metal, of which an example is shown in FIGS. I and 2. The conventional metal club head as shown in
Thus, it is desired to provide a weld structure of club head that overcomes the above drawback.
The primary purpose of the present invention is to provide a weld structure of a gold club head, which ensure efficient and proper positioning of a faceplate and a bottom plate in the welding of the faceplate and the bottom plate so that high quality product can be made in a short working time.
In accordance with the present invention, a club head is formed with openings respectively on top and bottom sides thereof and a circumferential recessed groove is formed in the club head along a circumference of each opening. Pegs are formed in and spaced along the circumferential grooves. A faceplate and a bottom plate are provided, each having a circumferential edge along which notches are formed in a spaced manner to correspond to the pegs. Thus, when the faceplate and the bottom plate are received in the top and bottom openings respectively to be supported by the circumferential grooves, the notches respectively snugly fit over the pegs to thereby securely and properly hold the faceplate and the bottom plate in position for subsequently welding operation. Thus, the subsequent welding operation can be carried out in a smooth manner.
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
When the faceplate 3 is set to close the opening 21 of the club head body 2, the notches 31 respectively engage the pegs 23 in a tight and abutting manner so that the faceplate 3 is properly positioned and secured. After the rings 32 are fit to the pegs 23, welding can be carried out on each ring 32. Since the notches 31 tightly abut against the pegs 23, the faceplate 3 is securely fixed against any potential shifting thereby enhancing the subsequent welding operation. In other words, such a weld structure ensures efficient and proper positioning of the faceplate 3 and can save a lot of time, as compared to the conventional structures, thereby providing improved quality and reduced flaw rate.
Referring to
When the bottom plate 4 is set to close the opening 24 of the club head body 2, the notches 41 respectively engage the pegs 26 in a tight and abutting manner so that the bottom plate 4 is properly positioned and secured. After the rings 42 are fit to the pegs 26, welding can be carried out on each ring 42. Since the notches 41 tightly abut against the pegs 26, the bottom plate 4 is securely fixed against any potential shifting thereby enhancing the subsequent welding operation. In other words, such a weld structure ensures efficient and proper positioning of the bottom plate 4 and can save a lot of time, as compared to the conventional structures, thereby providing improved quality and reduced flaw rate.
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.
