a and 2a are forcibly fitted into the two grooves 3 and 3, and the vicinity of the roots 2b and 2b are welded 4 to the face surface 1a. [Effect] It is possible to extend the flight distance only by adding a very simple improvement. The cost for improvement is low.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to an improvement in which a special plate is attached to the face surface of a club head so that the flight distance can be extended.

[0002]

[Prior art]

 Conventionally, in order to extend the flight distance, the material of the club head is made of titanium, or a special material is embedded inside the core of the club head.

[0003]

[Problems to be solved by the invention]

 These are not only very expensive, but they do not mean that you can use your existing club just by making improvements. The present invention has been developed as an alternative to such a thing, in particular, making it possible to use the existing club with very simple modifications.

[0004]

[Means for Solving the Problems]

 In the present invention, a sole plate 2 having an outwardly protruding arc shape with respect to the face surface 1a is attached to the face surface 1a of the club head 1 while keeping an appropriate distance d from the face surface 1a. When the sole plate 2 is attached to the face 1a of the club head 1 in this manner, the moment the golf ball is hit with the club head 1, the impact causes the sole plate 2 to bend slightly and the repulsive force and impact force This allows the golf ball to fly farther. That is, in the conventional case, the sole plate is attached in a state of contact with the face surface of the club head, whereas in the case of the present invention, an appropriate amount of space is provided between the club head 1 and the face surface 1a. The sole plate 2 is attached so that the interval d is maintained.

[0005]

[Embodiment of the invention]

 An example in which the present invention is applied to the first driver will be described in more detail. As shown in FIG. 1 (b), a sole plate 2 having an outwardly projecting arc shape with respect to the face surface 1a is provided on the face surface 1a of the club head 1 of the driver No. 1 with an appropriate distance d from the face surface 1a. Hold and attach. As an example of the mounting method, the left and right end portions of the sole plate 2 are bent inward, and the bent portions 2a, 2a are formed on the face surface 1a. 3 and the vicinity of the bases 2b, 2b is welded 4 to the face surface 1a and fixed.

The sole plate 2 is most preferably made of a metal (stainless steel) which is a metal having a high repulsive force. Assuming that the sole plate 2 is made of this material, the moment the golf ball hits the golf ball with the club head 1, the impact causes the sole plate 2 to bend slightly, and the repulsive force and impact force cause the golf ball to fly farther. Can be done. It is desirable that the thickness and the degree of curvature of the sole plate 2 and the distance d between the inner surface of the sole plate 2 and the face surface 1a be set to values that allow each player to fly the golf ball as far as possible. Since the force at the time of impact varies among individuals, the thickness, the degree of curvature, and the distance d may be determined in accordance with the individual differences of each player.

As shown in FIG. 1B, the interval d is formed between at least a core portion of the entire surface of the sole plate 2, that is, between the inner surface at the position where the golf ball is hit and the face surface 1 a. However, even if there is a slight interval over the entire sole plate 2, that is, at the forcibly fitted portions on both the left and right sides in FIG. 1B, there is no problem.

Since the sole plate 2 can be easily attached by forming the groove 3 in the face surface 1a of the club head 1, it is only necessary to improve the golf club which the golf club has to extend the flight distance. Also, the cost of improvement is low. It should be noted that a portion of the outer surface of the sole plate 2 serving as a core, that is, a portion where the golf ball is hit may be concentrically drawn so that its position can be confirmed.

[0009]

[Effect of the invention]

 According to the present invention, it is possible to extend the flight distance by adding a very simple improvement, and it is possible to reduce the cost of the improvement.
