Embodiment Construction

[0023] specific implementation plan

[0024] Hereinafter, the configuration of the present invention will be described in detail with reference to the drawings.

[0025] Figure 1(a) ~ Figure 1(c) Shown is the golf club head configured as the first embodiment of the present invention. Such as Figure 1(a) ~ Figure 1(c) As shown, the golf club head of this embodiment has a hollow structure, and its club head main body 1 is made of metal such as titanium alloy, aluminum alloy or stainless steel. The club head body 1 has a crown 2 , a face 3 , a sole 4 and a neck 5 . A hole 2 a is formed near the center of the crown 2 , and a hollow flange 2 b is formed around the periphery of the crown 2 . Furthermore, the hole 2 a is closed by the cover member 6 made of a material having a lower specific gravity than the club head body 1 . In addition, a reinforcement 7 made of fiber-reinforced plastic is laminated inside the face portion 3 of the club head body 1 .

Abstract

A hollow golf club head with high durability and high resilience features that its metallic hollow main body has a hole in the center of its top, the hole is blocked by a cover made of the material different from the material of said main body, which has a specific weight ration greater than 1.3, and a fibre reinforced plastics is attached to the face of said hollow main body with an area ratio greater than 20%.

Description

technical field [0001] The present invention relates to a golf club head having a hollow structure, and more specifically, relates to improving the repulsion property while maintaining the durability compared with the case of only being composed of a single metal material by compounding different kinds of materials, A hollow golf club head with increased design freedom. Background technique [0002] Metal hollow golf club heads generally achieve a low center of gravity by increasing the weight distribution on the sole. However, in recent years, the volume of the club head has been required to be as large as possible among the restricted mass of the club head, and the range of weight distribution for achieving a lower center of gravity and the like has been narrowed, and the degree of freedom in design has been reduced. Furthermore, there are inconveniences such as insufficient low center of gravity of the club head, and the repulsive force of the face cannot be exerted to t...
