DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to golf club heads, and more particularly to improvements in wood club heads.

Since the head of a golf club, generally called a wood club, is attached to a shaft that is longer than that of an iron club, a head with a large external shape and a large moment of inertia around the center of gravity is desired. However, since the weight of the head must be kept below a certain limit, it is necessary to increase the external shape of the head and the moment of inertia around the center of gravity without reducing the strength of the head.

In order to increase the outer shape of the head and the moment of inertia around the center of gravity, it is desirable to make the head a hollow structure, but if the generally widely used wooden head is made of a thin hollow structure, the strength will be significantly reduced. On the other hand, hollow metal heads that are integrally molded using the lost wax manufacturing method are known, but it is difficult to make them larger than wooden heads due to constraints on strength and weight.

Japanese Utility Model Application Publication No. 53-135069 discloses a head having a structure in which a head body is provided with layers of fiber-reinforced resin plates. Although such a composite structure is effective in improving the strength of the head, it is not possible to increase the external shape and the moment of inertia around the center of gravity simply by providing a fiber-reinforced resin layer of approximately constant thickness.

[Means for Solving the Problems] According to the present invention, a hollow joined body integral with the neck portion of the head is joined and fixed to a head main body made of a member lighter than the hollow joined body, and the hollow joined body is In a golf club head in which the outer shape of the head is formed by the outer periphery and the outer periphery of the head body, the hollow joined body has a recessed part in the center, and the joint surface of the hollow joined body to the head body is in contact with the face surface of the head. A golf club head is provided which extends substantially parallel to each other, wherein the hollow joint forms the back side of the head and the head body forms the face side of the head.

In the golf club head according to the present invention,
The weight distribution of the head can be shifted to the outer periphery of the head by the hollow joint integrated with the neck part, so the moment of inertia around the center of gravity of the head can be increased, and the hollow structure of the hollow joint allows the head to be Since the weight is reduced, the external shape of the head can be increased. Furthermore, since the joined body integral with the neck portion has a hollow structure, the strength of the head is increased. Therefore, it is possible to improve the strength of the head and to increase the external shape and moment of inertia around the center of gravity of the head.

FIG. 1 shows an embodiment of the invention. Referring to the figure, the head for a so-called wood club consists of a hollow joint 22 formed integrally with a neck portion 21 and a head body 23, and the head body 23 has a face surface 23a for hitting the ball. . The hollow joined body 22 has a joint surface 22a, and the joint surface 22
A concave portion 22b is formed in the center of a, forming a hollow structure. The hollow joined body 22 and the head main body 23 are bonded and fixed to each other via the joint surface 22a, and the outer periphery of the hollow joined body 22 and the outer periphery of the head main body 23 form a smoothly continuous external shape of the head. The joint surface 22a of the hollow joined body 22 extends substantially parallel to the face surface 23a. The hollow joined body 22 can be made of metal such as stainless steel or titanium, or fiber-reinforced metal. On the other hand, the head body 23
can be made of wood, plastic, fiber-reinforced plastic, etc., and is made of a lighter weight material than the hollow joined body 22.

In the golf club head having the above configuration, the weight distribution of the head can be biased toward the outer periphery of the head by the hollow joint 22 integrated with the neck portion 21, so that the moment of inertia around the center of gravity of the head can be increased. , and hollow joined body 2
2. The hollow structure reduces the weight of the head, so
It becomes possible to increase the external size of the head. In addition, in particular, since the hollow joint 22, which is heavier than the head body 23, is placed on the back side of the head, the center of gravity of the head shifts to the back side, resulting in a head with a deep center of gravity, which makes it difficult to remove the sweet spot. Even if the ball is hit, the head face surface 23a
The gear effect can further improve the flight direction of the ball.

As is clear from the above description, according to the present invention, the weight distribution of the head can be biased toward the outer periphery of the head by means of the hollow joint integral with the neck portion, thereby increasing the moment of inertia around the center of gravity of the head. In addition, the hollow structure of the hollow joined body reduces the weight of the head, making it possible to increase the external size of the head. Furthermore, since the joined body integral with the neck portion has a hollow structure, the strength of the head is increased. Therefore, it is possible to provide a golf club head that can improve the strength of the head and also increase the external shape of the head and the moment of inertia around the center of gravity.

In addition to the above-mentioned effects, according to the present invention, the hollow joined body with a high specific gravity is located on the back side away from the center of the head, so the weight is concentrated on the back side and the moment of inertia of the head becomes extremely large. . Therefore, even if you hit the ball off the sweet spot, you will still get a ball with good direction. In addition, the depth of the center of gravity from the face can be increased, and even if the ball is hit off the sweet spot, the moment acting on the head is reduced, resulting in a ball with good directionality. Further, since the depth of the center of gravity is deep, the distance from the shaft axis to the center of gravity of the head and the distance to the center of gravity of the entire club are both lengthened, and the swing trajectory is stabilized.
