Abstract

(57) Abstract: A wood club head in which a base is formed integrally and a top panel is formed integrally with a hitting surface. A wood club head is a hollow base integrally formed by casting, and has a top opening, a front opening communicating with the top opening, and a flange extending inward from a top periphery of the top opening. Including a hollow base having a top panel and a hitting surface integrally formed by forging,
The top panel is welded to the hollow base along an edge of the flange to close the top opening, and the striking surface is welded to the hollow base to close the front opening.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to golf clubs, and more particularly to wood club heads.

[0002]

[Prior art]

 Golf games use three types of golf clubs: putter, iron and wood clubs. Each type of club is designed for certain outdoor conditions and special distances.

[0003] Wood clubs with originally wooden heads are designed to hit the ball farther, but recently, wood club heads have become popular to be made of metal or alloy for high rigidity.

Referring to FIG. 3, a conventional wood club head comprises a base 70, a top panel 80, and a striking surface 90, and these three elements are generally forged. The base 70 has a top opening 72 and a front opening 74. The top panel 80 and the striking surface 90 are welded to the base 70, covering the top opening 72 and the front opening 74, respectively.

[0005]

[Problems to be solved by the invention]

 However, conventional wood clubs have the following disadvantages. 1. The base 70 is made by forging and cannot be integrally formed as by casting. Therefore, the shape of the base 70 is limited due to the nature of forging. Also, forging the base 70 is more expensive than casting, because of the multiple steps required to obtain the final product. 2. The top panel 80 is welded to the base 70, which inevitably impairs the stiffness of the wood club. The damage to stiffness is even greater, especially when welding is performed along the corner edges of the wood club as in a conventional wood club. 3. The top panel 80 and the striking surface 90 are welded together. Welding again impairs the stiffness of the striking surface 90 and significantly affects the performance of the wood club.

[0006] Accordingly, it is an object of the present invention to provide an improved wood club head that alleviates or eliminates the aforementioned disadvantages.

Another object of the present invention is to provide a wood club head which can be formed into various shapes by integrally molding a base. It is to reduce in comparison.

[0008] Yet another object of the present invention is to provide a wood club welded to a top panel base substantially away from a corner edge of the wood club head so as to minimize loss of stiffness of the wood club head due to welding. The purpose is to provide a head.

Yet another object of the present invention is to provide a wood club head in which the top panel is formed integrally with the hitting surface so that the fineness and rigidity of the top panel and the hitting surface are maintained.

[0010]

[Means for Solving the Problems]

 A wood club head according to the present invention that achieves the above object is a hollow base integrally formed by casting, and has a top opening, a front opening communicating with the top opening, and an inner periphery from the top periphery of the top opening. A hollow base having a flange extending inwardly, and a top panel and a hitting surface integrally formed by forging, wherein the top panel is formed along the edge of the flange on the hollow base so as to close the top opening. The hitting surface is welded to the hollow base so as to close the front opening.

[0011]

[Embodiment of the invention]

 Referring to FIGS. 1 and 2, a wood club head according to the present invention includes a hollow base 10, a top panel 20, and a striking surface 30.

The base 10 is integrally formed by casting so that a member constituting the base 10 has an appropriate thickness not less than 1.0 mm, and includes a top opening 12 and a front opening 14 communicating with the top opening. . A flange 16 extends inward from the top periphery defining top opening 12.

The top panel 20 and the striking surface 30 are integrally formed by forging, the top panel 20 has an appropriate thickness of 1.0 mm to 1.5 mm, and the striking surface 30 has a thickness of 2.4 to 3 mm. It has an appropriate thickness of 0 mm. Top panel 20 is welded to base 10 to close top opening 12, while striking surface 30 is welded to base 10 to close front opening 14. The weld between the top panel 20 and the base 10 is made along the edge 162 of the flange 16.

Due to the nature of the casting, various bases 10 can be made with many modifications to meet the needs of various golfers who strike golf balls at appropriate distances and directions. In addition, the appearance of the club head can be attractively designed for commercial purposes. In addition, casting the base 10 is less expensive than forging.

Due to the nature of forging, the rigidity of the top panel 20 and the striking surface 30 is high. Therefore, the thickness of the top panel 20 and the striking surface 30, that is, the plate-like member having the striking surface, can be made thinner and lighter than casting. Thus, the volume of the club head can be greater than 280 cm ³ , yet the club head still meets its weight standard.

It should be noted that the weld between the top panel 20 and the base 10 is such that the edge is substantially separated from the corner edge of the base so as to prevent compromising the rigidity of the wood club head. 162.

It should be noted as well. The top panel 20 and the striking surface 30 are integrally formed without welding, which minimizes welding damage that would otherwise impair the stiffness and fineness of the finished wood club head.
