Description of the Related Art Conventionally, a large hollow metal head is commercially available for metal wood, particularly a metal wood using a titanium material, in order to increase the moment of inertia of the head and to improve the flight direction. However, in order to increase the size of the hollow metal head, the thickness of the head body must be reduced due to the limitation of the weight of the head, which causes a problem in the strength of the head. In order to solve this, a method of providing a reinforcing rib inside the hollow metal head, forging a plurality of shells, or manufacturing by a method such as pressing,
There is known a method for reducing defects and the like inside metal.

という問題もある。As an example of a method for securing strength by providing a reinforcing rib inside a hollow metal head, Japanese Utility Model Application Laid-Open No. 58-91 has been proposed.
There is a hollow golf club described in Japanese Patent Application Publication No. 70-70, in which a reinforcing rib is provided on a back surface straddling a face portion or a face portion and a sole portion. However, providing the reinforcing ribs also causes an increase in weight due to the reinforcing ribs themselves, and it has been difficult to further increase the size while ensuring the strength of the head. When the rib portion is manufactured by casting, there is a problem that only a reinforcing effect smaller than the theoretical value can be obtained due to a defect inside the rib or the like.

とは困難である。A hollow metal head in which a plurality of shell portions are manufactured by a method such as forging or pressing and integrally joined by means of welding or the like is a hollow metal head manufactured by casting by reducing defects and the like inside the metal. Greater strength than head. Japanese Patent Application Laid-Open Nos. Hei 4-376678 and Hei 5-32992
No. 34, the hollow metal head is divided into three parts or four parts into a face shell, an upper shell, a sole shell, and a side shell, and the shells are integrally joined by means such as welding. The manufacturing method is an example of a method of manufacturing a hollow metal head by forging, pressing, or the like. But,
This also only makes the strength of each shell part close to the theoretical strength of the metal material, and it is difficult to further increase the size of the hollow metal head.

Was. On the other hand, JP-A-6-269518 describes that resilience can be improved by reducing the rigidity of the face portion and increasing the amount of elastic deformation of the face portion at the time of impact.
However, since the conventional reinforcing rib is provided over substantially the entire inner surface of the face portion, the rigidity of the face portion is increased, and the resilience performance of the impact is reduced.

It is to enable the realization of a head. Another object of the present invention is to reinforce the strength of the face portion without increasing the rigidity of the face portion, thereby improving the resilience performance due to the low rigidity of the face portion and ensuring the required strength of the entire hollow golf head.

も有効である。As described above, rib reinforcement increases the weight of the head by the weight of the rib itself. In order to increase the size of the head, it is desirable to reinforce the ribs in a narrower range and to reinforce them with smaller ribs. According to the studies made by the inventors, it has been found that the stress generated in the hollow golf head by hitting the ball is concentrated near the boundary between the face portion and the upper surface portion. This is considered to be due to the shape whose cross section is sharply bent from the face portion to the upper surface portion. Therefore, it is efficient that the rib reinforcement is performed near the boundary between the face portion and the upper surface portion, and it is appropriate to provide a plurality of reinforcing ribs having a bent portion on the inner surface of the boundary between the face portion and the upper surface portion. is there. The stress concentration near the boundary between the face part and the top part is due to the shape characteristics of the wood head and the hollow structure, as well as wood heads made of metal materials such as titanium, as long as the hollow structure, other than metal It is also effective for wood heads made of materials.

る。[0008] Such stress concentration is more severe in a hollow metal head in which a face shell, an upper shell and a plurality of other shells are integrally joined by means such as welding. This is presumably because not only the above-mentioned shape characteristics of the wood head, but also the boundary of the shell becomes an elastic boundary where reflection of elastic waves occurs due to the effect of welding or the like. Therefore, especially in a hollow wood head in which the face shell and the upper shell are separately manufactured and integrated by welding or the like, the rib reinforcement at the boundary between the face shell and the upper shell is more effective. .

ビード端部に設けるのが効率的である。As a result of more detailed analysis, stress concentration was highest at the end of the bead due to welding of the boundary between the face shell and the upper shell. It is considered that the change in wall thickness caused by the weld bead causes the end to be an elastic boundary. Therefore, it is efficient to provide the reinforcing rib provided at the boundary between the face shell and the upper surface shell at least at the end of the weld bead on the face shell side.

ことで、応力の集中を緩和出来ることも明らかである。From the above, it was found that stress concentration at the boundary between the face portion and the upper surface portion due to the shape characteristics of the head and stress concentration at the boundary portion between the face shell portion and the upper surface shell portion due to an elastic boundary such as a welded portion. Therefore, in a hollow golf head in which the face shell portion and the upper surface shell portion are separately manufactured and integrated by welding or the like, the face shell portion is extended to a part of the upper surface portion, so that the face portion that causes stress concentration is formed. It is also apparent that the concentration of stress can be reduced by separating the boundary between the upper surface and the boundary between the face shell and the upper shell.

る。The extension of the face shell in the direction of the upper surface is 5 m.
When it is set to about m to 20 mm, it can be efficiently reinforced with small ribs. If the extension of the face shell portion is 5 mm or less, the two stress concentration portions are too close to each other, and the concentration relaxation by separation is not sufficient. If it is 20 mm or more, it is necessary to separately provide ribs or provide long ribs.

型化と反発性の向上を両立することが可能である。On the other hand, when the face portion is made thinner in order to improve the resilience, a large concentrated stress is generated also in the face portion. However, if a rib is provided on the back surface of the sweet spot where the resilience is most desired to be improved, the rigidity of the face is increased and the resilience is not improved. Therefore, if a rib is provided on the back of the face portion at a position off the sweet spot, the resilience can be improved while maintaining the strength. Therefore, the reinforcement head provided at the boundary between the face portion and the upper surface portion and the boundary between the face shell portion and the upper surface shell portion extends vertically below the face shell portion outside the sweet spot, thereby increasing the size of the hollow head. And resilience can be improved at the same time.

にリブを設ける方法も同様に効果的である。In all cases where the ribs are reinforced as described above, the smaller the defects and the like inside the ribs, the more effective the reinforcement. Therefore, the head may be cut out from a forged, pressed, or rolled plate material. It is also effective to manufacture the member having a bent portion as a member separate from the main body, and integrate the bent portion with the inner surface of the boundary between the face portion and the upper surface portion of the hollow metal head by welding or the like. In a hollow metal head in which the face shell, the upper shell, and a plurality of other shells are integrally joined by means of welding or the like, when the face shell or the upper shell is manufactured by forging, pressing, or the like, simultaneously. The method of providing ribs is similarly effective.

That is, as shown in FIG.
A thin metal plate made of titanium or the like is forged and subjected to plastic processing to form a divided shell, for example, a face shell having a thickness of 2.4 mm, an upper shell having a thickness of 1.0 mm, a sole shell, and side shells.
