Hereinafter, for easy understanding of the present invention will be described based on the direction (up, down, left, right, before, after) shown in FIG. For example, the direction in which the golf club strikes the ball may be expressed as a 'backward' direction.

As shown in Figures 1 to 8, the golf club golf club head (1), as the game is made in a narrow space to increase the accuracy of the ball, and when hitting a light hitting sound to increase the user's interest, as well as durability It is to have.

In addition, due to the nature of the park golf only one golf club during the game, for this purpose it can be optimized according to the physical conditions such as the user's swing or physique.

The golf club head (1) for the park ball comprises a face member 100 is coupled to the head body 200 and the head body 200 to form a hitting surface 128 for hitting the ball.

The face member 100 includes a first concave member 120 having a first concave groove 122 formed on an opposite surface of the hitting surface 128, and a second concave in a direction opposite to the first concave groove 122. It comprises a second reinforcing member 140, the groove 142 is formed. In addition, the first reinforcing member 120 and the second reinforcing member 140 are coupled so that the first and second concave grooves 122 and 142 face each other, and thus the space portion between the first and the second concave grooves 122 and 142 is formed. 130 is formed, such a space portion 130 is formed, it is possible to make a distant flying distance with a high repulsive force when hitting.

The first and second reinforcing members 120 and 140 may have a cross-section having the same plate shape as the hitting surface 128 and may be made of a metal material or a hard synthetic resin material.

In addition, the edges of the first and second reinforcing members 120 and 140 that face each other, coupling grooves 124 and coupling protrusions 144 facing each other may be formed in a closed curve shape, and may be mutually fitted to each other.

In the disclosed embodiment, the coupling groove 124 is formed on the first reinforcing member 120 and the coupling protrusion 144 will be described based on the formation on the second reinforcing member 140.

However, the first reinforcing member 120 is not limited to the formation of the coupling groove 124, the coupling protrusion 144 may be formed, the coupling groove 124 is formed in the second reinforcing member 140. It may be.

Coupling groove 124 is preferably made of a form in which the inner side is widely extended. In addition, as shown in FIG. 3, the volume of the coupling groove 124 and the volume of the coupling protrusion 144 are the same, but the length of the coupling protrusion 144 is longer than the depth of the coupling groove 124.

In particular, when the first and second reinforcing members 120 and 140 are made of a metal material, the first reinforcing member 120 is preferably made of a metal material having a higher hardness than the second reinforcing member 140. This is to allow the coupling protrusion 144 of the same volume as the coupling groove 124 to be plastically deformed and filled in the coupling groove 124 at the time of indentation.

That is, as shown in (a) of FIG. 3, the coupling groove 124 formed in the first reinforcing member 120 is disposed in a state in which the coupling protrusion 144 formed in the second reinforcing member 140 is coupled. , As shown in (b) of FIG. 3, the coupling protrusion 144 is inserted into the coupling groove 124. In the just inserted state, the first reinforcing member 120 is spaced apart from the second reinforcing member 140 by a predetermined distance. In this case, as shown in (c) of Figure 3, the inner side of the coupling groove 124 of the form that is widely expanded, the coupling protrusion 144 having the same volume as the coupling groove 124 is plastically deformed. This is possible because the second reinforcing member 140 is made of metal having a lower hardness than the first reinforcing member 120.

Of course, although the first and second reinforcing members 120 and 140 may be integrally formed with the space 130, the first and second reinforcing members 120 and 140 may be separately provided, for example, to simplify the manufacturing process. It is preferable to combine.

Thus, by providing the first and second reinforcing members 120 and 140 made of a metal material, not only durability but also a light hitting sound when hitting can be obtained. This is because the sound is normally transmitted from a good elastic material, which is a property of returning to its original shape when the metal is deformed, since the metal is a strong elastic material and thus transmits sound well.

In addition, the volume center point of the golf club head, called a sweet spot, is a place where the optimum flying distance that can be expected from the golf club is possible, and the space portion 130 is formed, so that the repulsive force acts upon the hitting distance. Increase the

In addition, as shown in FIG. 4, the difference between the direction in which the ball enters and the direction in which the ball exits after the impact is not large. That is, even if it is out of the center it is to hold the direction in the space 130. (See angle 'α')

On off-center hitting of a conventional head, as shown in the rectangle in FIG. 4, the direction is lost. (See angle 'β')

In other words, when comparing the angle between the present invention and the prior art both in the same direction and the exit direction after hitting, 'α <β', even in the off-center hitting to hold the direction by the space portion 130 and sweet The range of spots can be increased, making it easier to hit.

Thus, the thickness of the face member 100 in a state where the first reinforcing member 120 and the second reinforcing member 140 are coupled may be 5 mm to 8 mm. This is to provide a space 130 in the face member 100 without impacting the metal due to the large impact amount because the center portion of the first and second concave grooves 122 and 142 is not too thin during the impact. . If the face member 100 made of metal is too thick (8 mm or more), the weight of the golf club itself is increased, thereby increasing the burden on the body that the user feels.

In addition, as shown in FIG. 6, letters and / or drawings may be laser engraved on the batter surface 128 for the user's personality.

On the other hand, the coupling surface 148 of the second reinforcing member 140 which is in contact with the head body 200, a plurality of coupling members 160: 126, to increase the coupling force with the head body 200 during insert injection molding 146, 166 may be provided.

When the balance member 180 is integrally provided with the first reinforcing member 120, the joints of the fixing part 127 and the fastening hole 147 may be welded for complete integration.

The golf club has the same weight, and the weight is completely different depending on which way you are swinging. When the balance weight 187 is fastened to the fixed portion 127, whether it is for left-handed use or for right-handed use, it is possible to mass-produce a large variety of products by only changing the weight of the balance weight 187 optimized for the user.

The balance weight 187 is preferably made of a material that is higher than the specific weight of the synthetic resin liquid used for insert injection.

In addition, according to the position where the balance weight 187 is installed, the low center of gravity design that puts the center of gravity of the head body 200 is also possible. For example, as illustrated in FIGS. 5A and 5B, the balance weight 187 may be located at a 'B' position.

In addition, when the balance weight 187 is located at the 'C' position so that the balance weight 187 is biased to one side (outward), the moment of inertia can be increased during the hit. The high moment of inertia maintains spin for longer than the ball's flight, sustains lift and increases distance, as well as accurate ball control.

In addition, the number of balance weights 187 provided is not particularly limited, and may be provided to be optimized for a user.

As described above, in the state in which the face member 100, the coupling member 160, and the balance member 180 are coupled to each other, the head body 200 is inserted into the coupling surface 148 by injection molding a synthetic resin solution to form a golf club. The head is completed.

This is to prevent the formation of scratches or the like on the surface of the head body 200 formed of a synthetic resin liquid during friction with the bottom surface of the golf course made of sand or the like during the game. (See Figures 7 and 8)

In addition, the plurality of long grooves 320 formed in the other direction is intended to overcome the disadvantages of the weight of the metal material (heavy than the synthetic resin liquid) by reducing the drag when the ball strikes, and continues to generate the lift.

On the other hand, the head body 200 is coupled to the opposite end of the hitting surface 128, the inside may be made of a solid or hollow shape further comprises a weight 400 to selectively add or subtract weight . This is to adjust the weight of the head body 200 according to the physical condition of the user by adding or subtracting the weight without departing from the original streamlined shape of the golf club except for the batting surface 128.

For example, in the case of a user who needs a larger weight, the user may fasten the weight 400 of the solid type, and if not, the weight 400 may not be fastened or may be fastened with the hollow weight 400. (See Figure 7)
