[0046] Hereinafter, a first embodiment of the golf club head of the present invention will be described with reference to the drawings. figure 1 It is a perspective view of the reference state of the golf club head of this embodiment, figure 2 yes figure 1 top view. Note that the reference state of the golf club head will be described later.

[0047]

[0048] Such as figure 1 As shown, the golf club head of this embodiment (hereinafter referred to as "club head" in some cases) is a hollow structure, and the wall surface is formed by the ball striking surface 1, the crown 2, the sole 3, the side 4 and the hosel 5.

[0049] The ball striking surface 1 has a ball striking surface, that is, a surface on which the ball is hit. The crown 2 is adjacent to the ball striking surface 1 and constitutes the upper surface of the club head. The sole 3 constitutes the bottom surface of the club head, adjacent to the ball striking face 1 and the side 4 . In addition, the side porti...

Embodiment

[0097] Hereinafter, examples of the present invention will be described. However, the present invention is not limited to the following examples.

[0098] (1) Preparation of Examples and Comparative Examples

[0099] Here, the golf club heads (drivers) according to the examples and the comparative examples in which the structure of the member for the ball striking face is different were produced as the contents in Table 1. Examples are those of the first embodiment described above Figure 1 to Figure 6 Golf club heads shown in . On the other hand, the comparative example differs from the examples only in that all thicknesses of the toe side edge, the center edge, and the heel side edge of the member for the face are the same, and the other structures are the same. As another structure, each head of the examples and comparative examples has a two-piece structure in which a head body made of a Ti-6Al-4V lost-wax investment casting and a head body manufactured by Nippon Steel ...

[0104] Hereinafter, a golf club head according to a second embodiment of the present invention will be described with reference to the drawings.

[0105]

[0106] Figure 9 It is a perspective view of a golf club head (hereinafter, sometimes simply referred to as a "club head") 100 according to this embodiment in a reference state, Figure 10 It is a plan view of the club head 100 in a reference state. In addition, the reference state of the golf club head will be described later. The club head 100 is a hollow structure, and the wall surface is formed by the ball striking face member 1 , the crown portion 2 , the sole 3 , the side portion 4 and the hosel portion 5 .

[0107] The face member 1 constitutes the front portion of the club head 100 for hitting a ball. The crown portion 2 is adjacent to the face member 1 and constitutes the upper surface of the club head 100 . The sole 3 constitutes the bottom surface of the club head 100 and is adjacent to the ball-striking fa...

Abstract

A golf club according to the present invention includes a golf club head body that has a crown portion and a sole portion and has an opening surrounded by the crown portion and the sole portion, and a face member that covers the opening of the golf club head body. The face member is formed in the shape of a cup having a face portion formed in a plate shape and a peripheral portion that extends from the peripheral edge of the face portion. In the peripheral portion of the face member, the portion that extends along the crown portion includes a first toe-side edge portion arranged on the toe side, a first heel-side edge portion arranged on the heel side, and a first central edge portion arranged between the first toe-side edge portion and the first heel-side edge portion.

Description

technical field [0001] The present invention relates to a golf club head. Background technique [0002] Wood-type golf club heads have been continuously improved, especially when it comes to No. 1 woods, and there are many proposals for extending the flight distance. As disclosed in JP 2005-6698 A, a so-called cup-shaped face structure is employed. Specifically, the club head is composed of a club head main body with an opening formed therein and a member for a ball striking face that closes the opening of the club head main body. and a peripheral portion extending from the periphery thereof. Providing such a peripheral portion on the ball striking face member can increase the amount of deflection of the ball striking face member when the ball is hit, thereby improving rebound performance and extending flight distance. [0003] In particular, in the golf club head disclosed in JP 2005-6698 A, rebound performance is improved by adjusting the wall thickness of the crown por...
