Abstract

PROBLEM TO BE SOLVED: To enable implementing of the setting and moving of the center of gravity of a head of a golf club easily and continuously. SOLUTION: A cylindrical slot 1 is provided inside a head and a cylindrical weight 2 is placed in the slot 1. The weight 2 is moved to a specified position in the slot 1 to set the position of the center of gravity of the head. The center of gravity of the head also can be continuously shifted by moving the weight 2.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to a golf club.

[0002]

2. Description of the Related Art Since the center of gravity of a conventional golf club head is fixed, when the player changes the position of the center of gravity in order to change the ball muscle of a hit ball, a lead plate is attached to the surface of the head with an adhesive tape or an adhesive. It is generally done to stick on. However, such a means cannot easily and continuously change the position of the center of gravity.

[0003]

SUMMARY OF THE INVENTION An object of the present invention is to make it possible to easily set the position of the center of gravity of a head and to make it possible to continuously move the head.

[0004]

According to the present invention, a cylindrical elongated hole is provided inside a head, a cylindrical weight is arranged in the elongated hole, and the weight is positioned at any position in the elongated hole. To continuously move the position of the center of gravity of the head.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows a case where the present invention is applied to a metal club (iron club). A cylindrical long hole 1 is provided inside a club head, and a female screw 7 is cut on the inner surface of the long hole 1. A cylindrical weight 2 corresponding to the long hole 1 is prepared, and an external thread 8 is cut on the outer surface thereof. The weight 2 is provided on its end face with a groove 9 corresponding to a screwdriver.

The weight 2 is screwed into the long hole 1 using the female screw 7 and the male screw 8. Then, the weight 2 is moved to a required position inside the long hole 1 using a screwdriver inserted from the end of the long hole 1. The position of the center of gravity of the head can be set by this position. When it is desired to move the position of the center of gravity, the weight 2 may be moved as appropriate.

FIG. 2 shows a case where the present invention is applied to a wood club. In the head, slots 3 and 4 are provided vertically in the club face, or slots 5 and 6 are similarly formed in the club face. Provided in the direction parallel to the face. The weight 2 is screwed into each of the long holes, and the position of the weight 2 is arbitrarily moved to set the position of the center of gravity or to be movable as in the case of FIG.

The long holes 3, 4 and the long holes 5, 6 may be provided together as shown in the figure, or only one of the long holes may be provided. Further, in the drawing, a plurality of elongated holes are provided in parallel with each other, but each may be one.

In the illustrated embodiment, the groove 9 is provided for moving the weight 2. Instead, a socket corresponding to the hexagon wrench is provided on the end face of the weight 2, and the weight 2 is formed by using a hexagon wrench. May be moved. In the case of a head having a hollow inside, a reinforcing frame is provided inside, so the elongated hole may be provided in this reinforcing frame. The weight of the weight 2 to be used may be appropriately selected according to the physical strength of the player.

[0010]

As described above, according to the present invention, the position of the center of gravity of the head can be easily set simply by appropriately moving the position of the weight disposed in the elongated hole provided inside the head. And the movement can be performed continuously.
