Abstract

PROBLEM TO BE SOLVED: To provide a head of a golf club increased in carry by optimizing the deformation of hit surface of the head of the golf club. SOLUTION: The wall thickness of hit surface of the golf club head is unequal according to the bending moment force generated in impacting a ball.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a golf club head that increases the flight distance of a golf ball.

[0002]

2. Description of the Related Art In recent years, in order to increase the flight distance of a golf ball, the material of a club head is made of metal (titanium).
Or stainless steel), the thickness of the striking surface is thin, and the head is hollow. Attempts have been made to reduce the weight, increase the head and increase the flying speed faster by that much, but it is remarkable. No effect.

[0003] A conventional golf club head 1 will be described below. FIG. 1 is a perspective view of a golf club head according to the present invention. FIG. 2 is a diagram showing an AA cross section of FIG. The thickness 15 of the hitting surface 10 is generally equal.

As shown in FIG. 3, the hitting surface 10 of the conventional club head has an irregular thickness (indicated by a dotted line) at the moment the ball hits, and the impact force is reduced. I do. Even if the weight is reduced and the swing speed is increased, the flight distance is not short.

[0005]

When the hitting surface 10 of the conventional golf club head described above has the same thickness, the surface is deformed abnormally and the flight distance is short.

An object of the present invention is to provide a golf club head capable of optimizing the deformation of the hitting surface of the conventional golf club head and extending the flight distance.

[0007]

Means for Solving the Problems In order to achieve the above object, the present invention solves the problems by making the thickness of the hitting surface of the golf club head unequal.

[0008]

Embodiment FIG. 4 and FIG. 5 are views showing a bending moment 25 generated on the hitting surface at the moment when the golf ball 20 hits the hitting surface 10. The thickness 15 of the striking surface 10 is determined from the bending moment. 4a and 5a show a wall thickness 15 in comparison with FIGS. According to this invention, the deformation of the hitting surface is optimized, an ideal repulsion force is obtained, and the flight distance is greatly increased.

As a synergistic effect, since the deformation of the hitting surface is optimal, the directionality of the ball is improved.

In the embodiment of the present invention, the external shape of the conventional head is not changed at all.
It meets the criteria of A.

[00011]

As described above, in the club head according to the present invention, the thickness of the striking surface is adjusted to the thickness in consideration of the bending moment generated when the ball hits the ball. By optimizing, the ideal repulsion is obtained and the flight distance is increased. As a result of making and testing an implementation model of the present invention, the repulsion was increased by 20 to 25% compared with the conventional example. As a synergistic effect, the directionality of the ball is improved because the deformation of the impact surface is not optimal. By devising the golf club head, a fun golf play can be performed, stress can be relieved, the golf population can be increased, and the economic effect can be contributed.
