In which, the golf club used for playing golf, because of the varieties in purposes and course geographies, are categorized into different types of clubs such as wood club, iron club, and putter.
- With respect to the wood club, the manufacturing of the golf club head is to typically use a metallic material for manufacturing a shell and for forming a striking plate on the shell for use to strike the ball. 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.
- To resolve the above issues, the conventional method proposes the forming of an annular engaged structure on the bonded surface of the shell and the striking plate for providing a method for improved bond rigidity. As illustrated in
FIG. 1A andFIG. 1B , a three dimensional exploded view and a cross-sectional view of conventional golf club head are respectively illustrated. The conventional method is to respectively set up an annular raisededge 122 and anannular notch 112 that are mutually engaged at the edge of thestriking plate 120 and the edge of theopening 110 a of theshell 110 for improved bonding strength between thestriking plate 120 and theshell 110. 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, theannular notch 112 and the annular raisededge 122 are more likely to have position errors, thus leading to the inability to tightly bond thestriking plate 120 and theshell 110. Furthermore, this type of design in conventional manufacturing process is also found to be unfavorable towards the fabrication of thinner club head. - 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.
- Based on the aforementioned and other purposes, the present invention proposes a golf club head, which mainly includes a shell and a striking plate. In which, the shell has an opening, and a portion of the edge at the opening of the shell has a first engagement portion. Furthermore, the striking plate is disposed at the opening, and together with the shell forms a club head body. A portion of the edge of the striking plate has a second engagement portion, corresponding to the first engagement portion, and the shell and the striking plate are mutually engaged respectively by means of the first engagement portion and the second engagement portion.
- In an embodiment of the present invention, the location of mutual engagement for the aforementioned shell and the striking plate is, for example, at the top portion of the club head body.
- In another embodiment of the present invention, the location of mutual engagement for the aforementioned shell and the striking plate for example is at the top portion and the bottom portion of the club head body.
- In another embodiment of the present invention, the location of mutual engagement for the aforementioned shell and the striking plate is, for example, at the top portion, a side portion, and the bottom portion of the club head body.
- In an embodiment of the present invention, the aforementioned first engagement portion includes, for example, at least a raised edge, and the second engagement portion, for example, includes at least a notch.
- In an embodiment of the present invention, the aforementioned first engagement portion includes, for example, at least a notch, and the second engagement portion, for example, includes at least a raised edge.
- In an embodiment of the present invention, the aforementioned golf club head, for example, further includes a bonding layer, and is disposed at the weld portion between the shell and the striking plate for bonding the shell and the striking plate.
- 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.

And the engagement location has a multitude of variations including, for example, a top portion of a club head body, the top portion and a bottom portion of the club head body, or the top portion, a side portion, and the bottom portion of the club head body, and other different embodiment configurations. The following shall include several concrete embodiments for describing the golf club head proposed in the present invention.
- 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 inFIG. 2A andFIG. 2B , thegolf club head 200 has aclub head body 202, in which theclub head body 202 is mainly formed from ashell 210 and astriking plate 220. In the present embodiment, theclub 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, theshell 210 has anopening 210 a. And the edge of the opening 210 a at a portion of theshell 210 has afirst engagement portion 212. In the present embodiment, thefirst engagement portion 212, for example, is a notch. And the notch, for example, is from the top portion of theshell 210, along a side portion, and extended to the bottom portion of theshell 210. - Referring again to
FIG. 2A andFIG. 2B , thestriking plate 220 is at theopening 210 a of theshell 210 for forming aclub head body 202 with theshell 210. In which, thestriking plate 220 corresponding to the edge of a portion of thefirst engagement portion 212 has asecond engagement portion 222 and is, for example, a raised edge, for allowing theshell 210 and thestriking plate 220 to be mutually engaged using thefirst engagement portion 212 and thesecond engagement portion 222. - In the present embodiment, the
first engagement portion 212 and thesecond engagement portion 222 respectively is, for example, a notch and a raised edge, which are to be mutually engaged. Furthermore, the present invention is to design thefirst engagement portion 212 as a raised edge, and thesecond engagement portion 222 designed as a notch. The most important fact is that the aforementionedfirst engagement portion 212 and thesecond engagement portion 222 are not necessarily required to be formed from a single continuous notch or raised edge. Thefirst engagement portion 212 and thesecond engagement portion 222 further can, for example, include a multitude of discontinuous notches or raised edges. Of course, the present embodiment is not to limit the types of thefirst engagement portion 212 and thesecond engagement portion 222 within a reasonable scope. The engaged structure adopted by the present invention further can be, for example, a protrusion and a cavity, or other types of structural combinations. - Referring once again to
FIG. 2A andFIG. 2B , the present invention is to further use welding (for example, brazing) on the bonding surface between theshell 210 and thestriking plate 220 to form abonding layer 240 for bonding theshell 210 and thestriking plate 220. In which, the method of forming thebonding layer 240 is, for example, coating the bonding agent on the bonding surface between theshell 210 and thestriking plate 220 prior to the engagement of theshell 210 and thestriking plate 220. After theshell 210 and thestriking plate 220 are engaged, further welding is conducted for allowing the bonding agent to melt and cool to form thebonding layer 240. Furthermore, theshell 210 can be first engaged with thestriking plate 220, and then the bonding agent is spread at the seam of the bonding location between theshell 210 and thestriking plate 220. After the bonding agent has melted and seeped into the bonding surface, further cooling and solidifying to forming abonding layer 240. One thing worth mentioning is that, if the processing environment is well-maintained during welding, the bonding agent not only can cover the bonding surface between theshell 210 and thestriking plate 220, but can also seep into the interior of theshell 210. And at the interior side of the bonding surface, the bonding agent is to solidify to form anannular welding support 242 between the weldedstriking plate 220 and theshell 210 for strengthening the bonding strength between theshell 210 and thestriking plate 220. - Based upon the aforementioned, the location of engagement between the
shell 210 and thestriking plate 220 of the present embodiment is at the top portion of theclub head body 202, above the side portion, and the bottom portion. The following embodiment shall propose several golf club heads in which the striking plate and the shell are engaged at different locations. -
FIG. 3A andFIG. 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 inFIG. 3A andFIG. 3B , theclub head body 302 of thegolf club head 300 of the present embodiment is similarly formed from ashell 310 and astriking plate 320. In comparison to the first embodiment, thefirst engagement portion 312 is also located at the edge of the opening 310 a at a portion of theshell 310, and is also, for example, a notch. However, the difference is that thefirst engagement portion 312 is at the top portion and the bottom portion of theshell 310. - Furthermore, a
second engagement portion 322 corresponding to thefirst engagement portion 312 is on the edge of a portion of thestriking plate 320, which is, for example, a raised edge, for allowing theshell 310 and thestriking plate 320 respectively to mutually engage using thefirst engagement portion 312 and thesecond engagement portion 322. Furthermore, the bonding location between theshell 310 and thestriking plate 320 can be welded (for example using brazing) to form abonding layer 340 for bonding theshell 310 and thestriking plate 320. - An important factor for consideration is that the types, quantities, and locations of the
first engagement portion 312 and thesecond engagement portion 322 of the present embodiment are also as varied as that described for the first embodiment. And the steps for forming thebonding layer 340 is the same as that described in the first embodiment; therefore, no further discussions are warranted. - Later, in reference to

Thesecond engagement portion 422, in which for example, is a raised edge, for allowing theshell 410 and thestriking plate 420 to mutually engage respectively using thefirst engagement portion 412 and thesecond engagement portion 422. Furthermore, the bonding location between theshell 410 and thestriking plate 420 can be welded (for example using brazing) to form abonding layer 440 for bonding theshell 410 and thestriking plate 420. - An important factor for consideration is that the types, quantities, and locations of the
first engagement portion 412 and thesecond engagement portion 422 of the present embodiment are also as varied as that described for the first embodiment. And the steps for forming thebonding layer 440 is the same as that described in the first embodiment; therefore, no further discussions are warranted. - Based on the above, the present invention is to form an engaged structure at the bonding location between the shell and the striking plate for improving the welding process. In which, the engaged structure is, for example, the combination of using a notch and a raised edge, or the use of other suitable structures, and the engagement locations can include a multitude of variations.
