Description

  The present invention relates to a golf club head, and more particularly to a golf club head excellent in the effect of absorbing vibration and impact at the time of hitting a ball.

  As shown in FIGS. 5 and 6, the conventional metal wood golf club head 1 has an opening 111 on a side where a hollow head body 11 is hit, and a face plate 12 for hitting a ball by welding, for example, is provided in the opening 111. There is a structure of coating. This conventional structure can significantly reduce the weight of the head and reduce the burden on both hands. In the meantime, the golfer's arm is injured and his golf fun is diminished. .

  FIG. 7 shows a club head having a vibration absorbing function (Patent Document 1). The club head 2 has an opening 211 on the side where the head body 21 having a hollow structure is hit. The face plate 22 is covered with the opening 211 by, for example, welding, and the head body 21 has a bottom portion on the face plate 22 side. The cavity 23 is provided with a vibration absorbing means filled with a semi-fluid liquid 24 having a predetermined viscosity. The vibration applied to the club head can be damped by the viscosity of the liquid 24.

However, the club head 2 can effectively attenuate the impact applied to the face plate 22 by the viscosity of the liquid filled in the cavity 23. However, the impact due to the face plate 22 is repeatedly applied, and the club head 2 is used for a long time. The cavity 23 may be damaged and the liquid 24 may leak. In addition, the vibration absorbing means takes time for manufacturing due to complicated construction such as injection of the liquid 24 and welding at the bottom, resulting in an increase in cost. Further, there is a problem that the inertial force of the liquid 24 having a predetermined viscosity affects the stability of the golfer's swing.

  The present invention has been made in view of the above-described problems, and can provide a golf club head that can greatly reduce the manufacturing effort of the vibration absorbing structure and has a long structure and a long service life of the entire club head. The purpose is to do.

  In order to achieve the above object, the present invention provides a golf club head having a hollow structure in which a face portion on a hitting side of a head body is opened and covered with a face plate. The face plate is a front plate on a hitting side. There is provided a golf club head characterized in that the rear plate on the back side and the rear plate are closely adhered to each other, and one of the plates is made of carbon fiber and the other is made of a titanium alloy.

  When the front plate is carbon fiber, the rear plate can be a titanium alloy. On the other hand, when the front plate is a titanium alloy, the rear plate can be made of carbon fiber.

  To make the configuration, a plurality of brackets each having a screw hole formed on the inner peripheral edge of the opening of the head body project toward the center of the opening, and the front plate and the rear plate have the A first through hole and a second through hole are provided corresponding to the screw holes, respectively, and the first through hole and the second through hole are inserted by screws and screwed into the screw holes. It may be.

  Further, the present invention provides a golf club head having a hollow structure in which a face portion on a hitting side of a head body is opened and covered with a face plate. The face plate includes a front plate on a hitting side and a rear plate on a back side And a plurality of brackets each having a screw hole formed at the inner peripheral edge of the opening of the head main body at the center of the opening. The front plate and the rear plate are provided with a first through hole and a second through hole corresponding to the screw holes, respectively, and the first through hole is provided by a screw. A golf club head characterized by being inserted through the second through hole and screwed into the screw hole.

  According to the golf club head of the present invention, it is possible to perform the function of buffering the vibration caused by the hitting ball by a simple vibration absorbing structure regardless of the viscosity of the liquid, and there is no liquid leakage due to the damage of the vibration absorbing structure of the conventional example, The service life can be extended.

  As a vibration absorbing means, the face plate has a structure in which either one of the front plate and the rear plate made of carbon fiber is in close contact with each other. be able to.

  In addition, a plate material is used as the vibration absorbing means configured as described above, and since it is fixed to the head body by a screwing method, its structure is strong and can be easily mounted, There is little manufacturing effort and it leads to cost reduction.
