Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a kind of golf club head structure, in particular, the hitting strength of the entire head is effectively increased, the shaft tilt angle has various selectivity, and it can be changed according to the demand. Further, the present invention relates to one in which tearing of the joint portion between the upper lid and the face is effectively prevented.

[0002]

[Prior art]

 As shown in FIG. 1, a golf club head manufactured by a general forging method has an upper constituent member 11, a lower constituent member 12, and a neck 131 integrally forged, and is welded by combining three pieces of a face 13. As a result, this combination method is not yet ideal in terms of structure and has at least the following drawbacks in use. 1. When the vibrating action at the time of strong hitting with the face 13 overcomes the joining force of the welded portion of the lower component 12 and the face 13, the face 13 is likely to fall off. 2. The neck 131 and the face 13 are integrally forged, and the inclination angle of the neck 131 is fixed and cannot be adjusted. Therefore, the shaft fitted to the neck 131 cannot be adjusted, and the user can adjust the angle according to his or her preference. It is no longer possible to select the shaft angle, which significantly reduces the product value and reduces the competitiveness of the golf club market. 3. When the upper end of the face 13 and the front end of the upper constituent member 11 were joined, a gap A was generated as shown in FIG. 2, and the gap A was filled with the welding material E and welded. The vibration force received later was transmitted to the front end X 1 of the upper component 11 close to the welding material E, so that the strength of the front end X was destroyed and the fracture was likely to occur.

[Problems to be solved by the device]

 The present invention has been made in order to improve a number of drawbacks of the conventional golf club head described above. Therefore, the present invention effectively increases the strength of the entire head against impact, and It is an object of the present invention to provide a kind of golf club head which has various options for the inclination angle of the shaft, can be changed according to demand, and effectively prevents tearing of the joint between the upper lid and the face. I am trying.

[0004]

[Means for Solving the Problems]

 According to the invention of claim 1, the bowl-shaped bottom seat 4, the upper lid 2 and the neck 3 are welded and combined, and the bowl-shaped bottom seat 4 is forged to integrally form the face 41 on the front side. A plurality of locking blocks 5 are provided at the front end of the locking block 5 by a downward press, and a curved portion 51 is formed at the bottom end of the locking block 5. The front end of the locking block 5 touches the rear surface of the face 41. Then, one space is formed between the face 41 and the face 41, and the space is filled with a welding material so that the upper lid 2 and the face 41 are welded and fixed to each other.

[0005]

[Embodiment of the invention]

 As shown in FIGS. 3 and 4, the present invention is a combination of a bowl-shaped bottom seat 4, a top lid 2 and a neck 3. The bowl-shaped bottom seat 4 is integrally manufactured by a forging method, a face 41 is simultaneously formed on the front side of the bowl-shaped bottom seat 4, and an arc-shaped recess 42 is formed at the upper end of the bowl-shaped bottom seat 4 and the face 41 on the right side. ing. The upper lid 2 is welded to the upper end surface of the bowl-shaped bottom seat 4, and the recess 21 formed at the right end of the upper lid 2 and the arc-shaped recess 42 of the bowl-shaped bottom seat 4 form one complete accommodation hole. Is formed, and the neck 3 is inserted into the accommodation hole and welded. Thus, the welding combination form of the present invention is completed, and the surface thereof is modified and smoothed to obtain the golf club head shown in FIG.

A locking block 5 is formed downward on the front end of the upper lid 2 by press working, and a curved portion 51 is formed at the bottom end of the locking block 5 (see FIGS. 5 and 6). . A slight protruding block 22 is formed at the rear end of the upper lid 2, and when the upper lid 2 is combined with the face 41 downward, the protruding block 22 hits the upper surface of the bowl-shaped bottom seat 4 to generate a positioning effect, When the front end of the locking block 5 comes into contact with the corresponding position on the rear side surface of the face 41, a space S is formed between the locking block 5 and the face 41, and the welding material E fills the space S (FIG. 6, 7) See, when the welding of the upper lid 2 and the face 41 is completed, the combination of the upper lid 2 and the bowl-shaped bottom seat 4 is completed, and when the surface is corrected and smoothed, the protruding block 22 is also corrected and scraped off. .

The bowl-shaped bottom seat 4, the upper lid 2 and the neck 3 of the present invention are all made of titanium alloy, so that the weight of the entire golf club head is light, the strength is large, and the best impact effect is exhibited. You can

When the bowl-shaped bottom seat 4 of the present invention is directly forged integrally with the face 41, the face 41 and the bowl-shaped bottom seat 4 do not have an abutting surface, so that the impact strength of the face 41 is increased. At the same time, the bowl-shaped bottom seat 4 compensates for the lack of strength of the face 41, and the face 41 effectively absorbs vibration and does not fall off after impact, and the overall combined strength is increased.

Furthermore, since the neck 3, the bowl-shaped bottom seat 4, and the top lid 2 are manufactured separately and then welded together, the inclination angle of the neck 3 must be adjusted to the angle required by the user. It is possible to fix the shaft at various angles by welding and fixing the bottom base 4 and the upper lid 2 and further inserting and fixing the shaft in the neck 3. Therefore, it can be selectively manufactured according to the market demand and the customer demand (see Fig. 8), and it can meet the demands of the market and the customer, thereby enhancing the product value and the competitiveness in the market.

At the time of welding and fixing the face 41 and the upper lid 2, a positioning effect can be obtained by first bringing the projecting block 22 into contact with the upper rear side of the bowl-shaped bottom seat 4, and the butt welding work of both can be performed. This positioning effect can be achieved quickly and with labor saving.

The strong vibration generated when the face 41 is struck is transmitted by the curved portions 5 at the bottom ends of the plurality of locking blocks 5 dispersedly to the upper lid 2, and the upper lid 2 receives it on average (see FIG. 9). Since the upper lid 2 is not concentrated in one place, the rupture of the welded portion between the upper lid 2 and the face 41 is reliably prevented.

[0012]

【The invention's effect】

 The golf club head of the present invention effectively increases the impact strength of the entire head, and has various options for the inclination angle of the shaft, which can be changed according to the demand. The rupture of the joint is effectively prevented.
