Benefits of technology

[0008] Based on the aforementioned, the purpose of the present invention is to provide a golf club head which takes into account of weld rigidity as well as manufacturing yield.
[0016] Based on the above, the present invention forms an engaged structure at the welded portion between the shell and striking plate for the sake of weld assisting. Therefore, the shearing strength of the welded portion is effectively improved. Furthermore, because the present invention only forms an engaged structure at the welded portion of a portion of the shell and the striking plate, therefore fabrication is easier, and also effectively reduce the position errors caused by process temperature variation and other factors, thus can effectively increase manufacturing yield.

Problems solved by technology

The conventional manufacturing of the golf club head, due to limitations based upon the differences in the metallic materials of the shell and the striking plate, are mostly using the brazing method for bonding the shell and the striking plate.
Although the brazing bonded golf club head possesses base plate structural strength; nevertheless, the bonded surface's shearing strength is poorer.
Therefore, after a multitude of ball strikes, the bonding portion between the shell and the striking plate exhibits cracks, which eventually leads to the separation of the striking plate from the shell.
However, although this type of annular engaged structure can provide adequate bonding strength, the precision requirement and fabrication cost are correspondingly increased.
Otherwise, it is possible that due to manufacturing errors or process temperature variations, the annular notch 112 and the annular raised edge 122 are more likely to have position errors, thus leading to the inability to tightly bond the striking plate 120 and the shell 110.
Furthermore, this type of design in conventional manufacturing process is also found to be unfavorable towards the fabrication of thinner club head.

first embodiment

[0024] A three dimensional exploded view and a cross-sectional view of a first embodiment of the present invention respectively illustrates a golf club head, as in FIG. 2A and FIG. 2B. As illustrated in FIG. 2A and FIG. 2B, the golf club head 200 has a club head body 202, in which the club head body 202 is mainly formed from a shell 210 and a striking plate 220. In the present embodiment, the club head body 202 can be, for example, selected from typical metallic materials (such as stainless steel or other metallic materials) to use casting method to form a unibody construction. Furthermore, the shell 210 has an opening 210a. And the edge of the opening 210a at a portion of the shell 210 has a first engagement portion 212. In the present embodiment, the first engagement portion 212, for example, is a notch. And the notch, for example, is from the top portion of the shell 210, along a side portion, and extended to the bottom portion of the shell 210.

[0025] Referring again to FIG. 2A ...

second embodiment

[0029]FIG. 3A and FIG. 3B respectively illustrates a three dimensional exploded view and a cross-sectional view of a golf club head, according to a second embodiment of the present invention. The engagement location for the shell and the striking plate of the present embodiment is above the top portion and the bottom portion of the club head body. As illustrated in FIG. 3A and FIG. 3B, the club head body 302 of the golf club head 300 of the present embodiment is similarly formed from a shell 310 and a striking plate 320. In comparison to the first embodiment, the first engagement portion 312 is also located at the edge of the opening 310a at a portion of the shell 310, and is also, for example, a notch. However, the difference is that the first engagement portion 312 is at the top portion and the bottom portion of the shell 310.

[0030] Furthermore, a second engagement portion 322 corresponding to the first engagement portion 312 is on the edge of a portion of the striking plate 320,...

third embodiment

[0032] Later, in reference to FIG. 4A and FIG. 4B, in which a three dimensional exploded view and a cross-sectional view of a golf club head of a third embodiment of the present invention are respectively illustrated. The engagement location of the shell and the striking plate of the present embodiment is only at the top portion of the club head body. As illustrated in FIG. 4A and FIG. 4B, the golf club head body 402 of the golf club head 400 is formed from a shell 410 and a striking plate 420, in which the first engagement portion 412 is disposed at the edge of the opening 410a at the top portion of the shell 410.

[0033] Futhermore, a second engagement portion 422 corresponding to the first engagement portion 412 is on the edge of the top portion of the striking plate 420. The second engagement portion 422, in which for example, is a raised edge, for allowing the shell 410 and the striking plate 420 to mutually engage respectively using the first engagement portion 412 and the seco...

Abstract

A golf club head which mainly includes a shell and a striking plate is provided. In which, the shell has an opening, and a portion of the edge of the opening of the shell has a first engagement portion. Furthermore, the striking plate is located at the opening, and with the shell forms a golf club head. A portion of the edge of the striking plate has a second engagement portion, which is corresponding to the first engagement portion. The shell and the striking plate are mutually engaged respectively using the first engagement portion and the second engagement portion. The golf club head has superior structural strength and manufacturing yield.
