Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a golf club head, and more particularly to a golf club head having both a strong striking force and excellent controllability.

[0002]

[Prior art]

 Golf is a sport in which a golf ball placed on the ground by a sudden swing of a golf club is hit by the club head to fly the golf ball to a desired target and put it in a hole.However, the golf ball is extremely small and Due to the high hardness, the ball line / behavior of the ball is almost determined at the moment when the club head hits the ball. For this reason, golf can be said to be a difficult sport, and in order to improve golf, it is important not only to practice and experience, but also to select a golf club.

[0003]

[Problems to be solved by the device]

 By the way, it is essential that a good golf club not only be able to fly a golf ball to a long distance, but also have excellent directionality and controllability for accurate launch. The golf club heads that are often seen today include metal molded products such as aluminum alloy and stainless steel, wooden products, and those in which a hitting face made of wood is fitted into the striking face.

Of these, the one made of metal has a high surface hardness, and the contact with the ball at the time of hitting is performed at almost one point, so at the moment of hitting, a small golf ball is dominated by the intention and experience of hitting. It had already jumped out when it hadn't arrived yet, and the controllability was extremely poor. That is, the higher the hardness of the club head, the quicker the reaction of the golf ball that is hit, and even the slightest error at the time of hitting causes the ball to fly out in an unexpected direction.

On the other hand, when the hitting face is soft, it is easy to control because the reaction of the hit ball is slow, but the hitting force is poor and it is not good to fly the hit ball far. Thus, it is difficult to achieve both controllability and long-distance striking power at the same time, which is one of the complaints of golf lovers.

As a result of earnest research to solve the above-mentioned problems relating to golf clubs, the present inventor has developed a golf club that has both controllability and long-distance striking force by incorporating a special structure in the club face. It was successfully developed and is proposed here as the present invention.

[0007]

[Means for Solving the Problems]

 According to the invention, the hitting portion 13 of the golf club head body 10 is provided with a hitting portion 13 and a neck portion 11 provided at the top end for connection with the club shaft. A hitting face having a constant thickness, which is composed of a metal mesh-like rigid body 22 continuously cross-linked to the above and a flexible body 24 filled and fixed in a space surrounded by the mesh 21 of the metal mesh-like rigid body 22. The above problem is solved by inserting 20.

[0008]

[Action]

 The space surrounded by the mesh 21 of the metal mesh rigid body 22 of the hitting face 20 is filled with the flexible body 24. Therefore, when hitting the golf ball 25 with this, the probability that the hitting point hits the mesh 21 is Extremely large, the hitting point causes the flexible body 24 to be compressed and deformed to cause a cushioning action, and accordingly, the hitting out of the ball 25 is delayed. Finally, as shown in FIG. 3, the golf ball 25 comes into contact with the metal net-like rigid body 22 which is interconnected and crosslinked, the hitting point becomes a multi-point contact state, and the reaction force is generated at each contact point. When F occurs, a huge thrust P is generated in the axial direction, and the golf ball 25 is rapidly sent out according to the player's will. As shown in FIG. 3, the mesh 21 of the metallic mesh-like rigid body 22 appropriately limits the angle of reflection of the hit ball during the delivery, so that the direction of the hit ball is surely grasped, and the ball 25 is surely grasped. The power of hitting is not lost, and the ball 25 is hit far and accurately.

【Example】

 FIG. 1 is a perspective view showing a golf club head according to an embodiment of the present invention with a hitting face removed, FIG. 2 is a perspective view showing a state in which the hitting face is fitted, and FIG. FIG. 4 is a front view of another embodiment of the hitting face, and FIG. 5 is a front view of the other embodiment.

In the figure, reference numeral 10 denotes a golf club head body, which is made of metal such as stainless steel and aluminum alloy, composite material such as carbon fiber and glass fiber, and wood. The head body 10 is provided with a neck portion 11, which is used for connection with the club shaft, a crown portion 12 which is the top of the arc surface, and a hitting portion 13 which receives a hit ball, as in the conventional case. As shown in FIG. 1, the hitting portion 13 is provided with a step for fitting a hitting face 20 described later. The hitting face 20 is a feature of the main body device. As shown in FIGS. 1 and 2, a metal mesh rigid body 22 having a constant wall thickness, which is interconnected and cross-linked in a mesh shape, is a main construction plan. The space defined by the mesh 21 in the metallic mesh rigid body 22 is filled and fixed with the flexible body 24, and a plurality of reinforcing ribs 23 are radially stretched and fixed on the back surface thereof.

The hitting face 20 has a plane shape corresponding to the hitting portion 13 having the above-mentioned recess. As the flexible body 24, a composite material made of carbon, ceramics, aramid fiber, ABS resin, boron, glass fiber, polyurethane, rubber or the like is preferably used. The surfaces of the flexible body 24 and the mesh 21 are formed so as to be smooth (one surface). The shape of the mesh 21 is not limited to the hexagonal shape shown in FIGS. 1 and 2, but may be another shape, for example, a circle as shown in FIG. 4 or a lattice shape as shown in FIG.

In this embodiment, as described above, the hitting face is configured by integrally bonding the hard one (metal mesh rigid body 22) and the soft one (soft body 24). By fitting this into the hitting portion 13 of the head body 10 and connecting it to the shaft (not shown) by the neck portion 11, it is possible to obtain a golf club capable of exhibiting powerful hitting and excellent controllability at the same time. . The space surrounded by the mesh 21 of the metal mesh rigid body 22 of the hitting face 20 is filled with the flexible body 24. Therefore, when hitting the golf ball 25 with this, the probability that the hitting point hits the mesh 21 is Extremely large, the hitting point causes the flexible body 24 to be compressed and deformed to cause a cushioning action, and accordingly, the hitting out of the ball 24 is delayed. Finally, as shown in FIG. 3, the golf ball comes into contact with the metal net-like rigid body 22 which is continuous with each other in a net-like shape, and the hitting point becomes a multipoint contact state. A reaction force F is generated to generate a huge thrust P in the axial direction, and the golf ball 25 is rapidly sent out according to the player's will. During the delivery, the mesh 21 of the metal mesh-like rigid body 22 appropriately limits the angle of reflection of the hit ball so that it does not become excessive. The ball 25 is launched far and accurately.
