[Structure] A club head main body 1 comprises a club head outer shell 3 having a hollow portion 2 and a face portion 6 which can be fitted into an opening 4 of the club head outer shell 3 via a contact portion 5 by a spigot. It is configured. The entire circumference of the butt-fitting portion 7 between the club head outer shell 3 and the face portion 6 is covered with the adhesive 8
The back metal 9 for weight adjustment is fixed to the back side of the hollow portion 2 by an adhesive or welding.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a wood golf club head. More specifically, the club head outer shell and the face portion can be made of different materials, and the space inside the club head outer shell can be effectively used. It is related to the improvement of the wood golf club head that can be used.

[0002]

[Prior Art]

 Conventionally, as a wood golf club head such as a metal wood, a club head outer shell having a hollow portion and a face portion are separately molded with a metal material, and a joint portion between the club head outer shell and the face portion is welded or the like. There is known a method of forming by joining, or a method of forming a club head main body having a hollow portion in two at the center, fitting each with a spigot, and joining by welding or the like.

[0003]

[Problems to be solved by the device]

 However, as described above, most of the club head joints made of metallic materials have a welded structure, which requires a lot of time and labor for joining and finishing operations, resulting in an increase in cost. However, there is a problem that it is difficult to put an organic substance in the hollow part of the club head due to the heat of welding. In recent years, special metal materials (such as titanium) have been used. In the case of a club head, there is a problem that it costs a lot to finish and process, resulting in cost increase.

The present invention has been made in view of such conventional problems. The club head outer shell and the face portion are joined by a non-welded structure so that the club head is made of a different material. It is an object of the present invention to provide a wood golf club head that can be manufactured at low cost by making it possible to effectively use the hollow portion of the club head and further facilitating the molding operation. .

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention comprises a club head outer shell having a hollow portion and a face portion which can be fitted into an opening portion of the club head outer shell through an abutting portion. The gist is that the fitting portion between the shell and the face portion is fixed with an adhesive.

[0006]

[Function of the device]

 This invention is configured as described above, and the club head outer shell having a hollow portion is formed by sheet metal, press working, or the like, and the face to be fitted into the opening of the club head outer shell through the contact portion by the spigot. Parts are manufactured by forging, etc., and the structure in which the fitting part between the club head outer shell and the face part is fixed with an adhesive agent, the impact force received by the face part is received by the contact part. This makes it possible to maintain the strength, makes the manufacturing process extremely easy, and allows the hollow part to be filled with an organic material.Because the face part is joined using an adhesive, it is possible to use other materials. It is also possible to use the configured face portion.

[Example of device]

 An embodiment of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a cross-sectional view of a wood golf club head embodying the present invention. The club head body 1 includes a club head outer shell 3 having a hollow portion 2 and an opening 4 of the club head outer shell 3. It is composed of a face portion 6 which can be fitted by a spigot via the contact portion 5.

The entire circumference of the butt-fitting portion 7 between the club head outer shell 3 and the face portion 6 is fixed via an adhesive 8, and the back side of the hollow portion 2 has a weight adjusting bag. The cumetal 9 is fixed by an adhesive or welding. In this invention, since the club head outer shell 3 and the face portion 6 are joined together with the adhesive 8 as described above, the club head outer shell 3 and the face portion 6 are made of the same material such as metal. Of course, the material of the club head outer shell 3 can be made of metal and the material of the face portion 6 can be made of carbon, and since it is not joined by welding, there is no effect of heat, and therefore the club is not. A hollow body 2 of the head shell 3 can be provided with a core body made of an organic material such as syntactic foam, and is not deformed by heat. Therefore, the face portion 6 and the back metal 9 are connected to each other. It is also possible to simultaneously attach such parts at the time of bonding.

As described above, in the present invention, the club head outer shell 3 having the hollow portion 2 is formed by sheet metal, press working or the like, and the opening 4 of the club head outer shell 3 has the abutting portion 5 interposed therebetween. The face portion 6 to be fitted with the spigot is manufactured by forging, etc., and the entire circumference of the fitting portion 7 between the club head outer shell 3 and the face portion 6 is fixed through the adhesive 8. As a result, the impact force received by the face portion 2 can be maintained by being received by the contact portion 5, and since the welding structure is not used as in the conventional case, the manufacturing process becomes extremely easy. Also, the hollow portion 2 can be filled with an organic material or the like, and since the face portion 6 is joined using the adhesive 8, it is possible to use the face portion 6 made of another material. It will be.

[Effect of the device]

 This invention comprises a club head outer shell having a hollow portion as described above, and a face portion which can be fitted into an opening of the club head outer shell via an abutting portion. Since the mating part with the face part is fixed with an adhesive, the club head can be made of a different material by joining the joint part between the club head outer shell and the face part with a non-welded structure. In addition, the hollow part of the club head can be effectively used, and further, the molding work can be facilitated, so that the manufacturing cost can be reduced.
