金属製中空殻体とされるウッドクラブヘッドの補強構造
に関する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reinforcing structure for a wood club head which is a metal hollow shell having a head volume of 250 cc or more.
【０００２】[0002]

みや亀裂が生じ易くなることが懸念されてきた。2. Description of the Related Art For the purpose of increasing the flight distance, a wood club head having a large hollow shell structure made of metal is mainly used. As a result, the impact force at the time of hitting the ball is increased, and there has been a concern that dents and cracks are likely to be generated in a part of the head by repeatedly receiving such a force.

橋絡するようなリブを設置する補強も行われている。[0003] For this reason, hitherto, the hitting surface which directly receives the greatest force is conventionally made to be thicker than other parts of the head, or to be provided with ribs of various shapes on the back side of the hitting surface. Has been made. In addition, in consideration of unexpected usage conditions, reinforcement to install ribs at the boundary between the striking surface, that is, the face surface and the other shell surface of the head connected thereto, so as to bridge between the surfaces sandwiching the boundary portion is also required. Is being done.

じるからである。However, whether the thickness of the face is increased, ribs are provided on the back surface of the face, or ribs are provided on the boundary portion around the face, the head weight is increased in terms of club performance. It is necessary to suppress the movement of the center of gravity and the forward movement of the position of the center of gravity. That is, the head weight is suppressed to about 200 g. If the weight is increased more than this, it becomes difficult for a general player to perform a club swing, and the face side becomes heavy due to reinforcement, and the center of gravity of the head moves to the face side (forward). Then, there arises a problem that the so-called sweet area becomes small and the number of missed shots with the core removed increases.

SUMMARY OF THE INVENTION An object of the present invention is to provide a wood club head having a large hollow shell structure which is excellent in durability with little increase in head weight and little forward movement of the center of gravity.

れたものである。According to the endurance test, the inventor has noticed that the damaged portion of the large head having the metal hollow shell structure is not limited to the face portion but occurs on each shell surface of the head except the sole. Then, the stress distribution on each shell surface of the head during hitting was analyzed by an actual hitting test. In the test, several test golf clubs with brittle paint applied on the entire surface of the head were prepared, and several golfers were allowed to test a golf club for about one month at the driving range. It was done by observation. The head of the test club was made of titanium alloy and 270 cc in volume.
The thickness of the face is 2.5mm, the thickness of the sole is 3mm,
The thickness of the other head shell surface is 1.5 mm, and
A rib is welded to a boundary portion between the face surface and another shell surface of the head connected thereto so as to bridge a surface sandwiching the boundary portion.

That is, it has been clarified that torsional deformation due to buckling generated on the crown and the shell surface of the side cannot be avoided only by the conventional reinforcing means described above. Moreover, it was found that the buckling occurred at a position where the number density of wrinkles generated in the brittle paint was high, due to the main stress acting on the wrinkles in the vertical direction. Therefore, in the present invention, reinforcing ribs are provided on the back surface of each shell surface constituting the head except for the face and the sole along the direction of the main stress detected by the wrinkles of the brittle paint, and the buckling is performed.

When the rib width (thickness) and height are less than the lower limit, the rigidity of the rib is insufficient, and when the rib exceeds the upper limit, there is a concern that the head weight is excessively increased. If the length of the rib is less than the lower limit, reinforcement of the target shell surface of the head cannot be performed in a sufficient range.If the length exceeds the upper limit, the head weight increases. The problem comes out.

Torsional deformation due to buckling is suppressed or prevented, and the durability of the head can be significantly improved. Further, according to the reinforcing means of the present invention, in each shell surface excluding the face and the sole of the head, only the region where the main stress is the largest is reinforced by the rib having the minimum necessary shape, so that unnecessary weight is reduced. There is no increase, and therefore, the increase in the head weight is extremely small, and there is no fear of adversely affecting the club swing. Also, the concern of the conventional product that the center of gravity of the head moves forward for reinforcement and the sweet area is reduced is solved.
