Abstract

PROBLEM TO BE SOLVED: To enlarge a head while holding the strength of a face part by forming the thickness of a center part of a face part into such thickness as enduring the impact with a ball and setting the thickness in the circumference of the center part thinner than that of the center part so as to provide spring performance with the whole of the face. SOLUTION: In a golf club head 1 formed from a metal material, the thickness T1 of a center part 3 including a sweet spot of a face part 2 is formed into such thickness T1 enduring the impact with a ball and the thickness except for the center part 3 is formed thinner than the center part 3. Namely, an adjoining circumferential part 4 in the adjacent to the center part 3 and an outer circumferential part 5 expanded toward the outside than the adjoining circumferential part 4 are formed and their thickness are so changed as to become thinner as separated from the center part 3. The weight is thus reduced while holding the strength of the face part 2, this reduced weight can be redistributed, and the head 1 can be enlarged without changing the head weight.

Description of the Related Art In a conventional golf club head formed of a metal material, for example, a wood-based head (metal head) formed of stainless steel, the thickness of the face portion is large enough to withstand impact with a ball. Since strength is required, it is necessary to make the wall thickness thicker than the crown portion, the sole portion, the side peripheral portion, and the like. Even with a stainless steel metal head, it is necessary to enlarge the sweet area to increase the moment of inertia, deepen the center of gravity, and make it easier to hit. A stainless steel metal head with a head volume of over 200cc has also been developed. When increasing the size of the head, it is necessary to reduce the wall thickness to suppress an increase in weight. However, due to the strength of stainless steel, the face portion needs to have a wall thickness of about 3 mm. Moreover, in order to make the thickness of the entire face portion uniform, the thickness of portions other than the face portion was made as thin as possible to increase the size of the head.

It is also possible to use a metal material such as titanium or its alloy, or aluminum or its alloy. The wall thickness of the face portion 2 is partially changed according to the strength of the material used. The center portion 3 has only to have a thickness that is necessary and maintains sufficient strength, and need not be thicker than necessary.
For example, in the first embodiment, if the entire face portion 2 is formed with a thickness equal to or less than the thickness of the adjacent peripheral portion 4 and the peripheral peripheral portion 5, the strength is uneasy, but the thickness of the center portion 3 causes a ball impact. Since the face portion 2 has sufficient strength to withstand, the face portion 2 as a whole can withstand repeated impacts with the ball even if the other portions are thinner than the center portion 3. When the head 1 is made of a titanium alloy and the center portion 3 has a thickness of 2.5 mm and can withstand impact with a ball, the center portion 3 may be slightly thickened to 3 mm. When the ball is hit at the center point 3, the feel is good if the thickness is set to have a margin rather than the limit.

なる。The third embodiment shown in FIG. 5 shows an example applied to the head of an iron club, and the thickness of the center portion 33 including the sweet spot of the face portion 22 of the head 11 is sufficient to withstand the impact with the ball. It is formed to have a thickness that maintains sufficient strength, and the peripheral portion 44 is thinner than the center portion 33. The thickness t 1 of the center point 33 is 8 m
The thickness t 2 of the peripheral portion 44 is set to about 1.5 mm. The numerical value of the wall thickness in this case shows the case of stainless steel or soft iron, but in the case of titanium and its alloys, aluminum and its alloys, the respective thicknesses are also different. Since the peripheral portion 44 is thin, the rigidity of this portion is lower than that of the center portion 33, and the portion is easily deformed, the spring effect of the entire face is improved, and the repulsion of the ball is improved.

Since the thickness of the peripheral part of the center part is thinner than that of the center part to give the whole face elasticity, it is possible to increase the size of the head while maintaining the strength of the face part. In addition, the repulsion of the ball is improved by reducing the thickness of the peripheral portion of the face portion so that the entire face has elasticity.
