Problems solved by technology

The disadvantage of this hitting head is that the deflection of the hitting face member when hitting the ball is limited by the elastic material, so the rebound performance is reduced.

Embodiment

[0059] According to Table 1, an iron type golf club hitting head with a lie angle of 24° was trial-produced. Each head is made of SUS630 head body molded by the lost wax investment casting method and the ball face member made by punching 6Al-4V-Ti plate and then finished by NC. Adhesive is applied simultaneously , by pressing in and as in image 3 shown riveted to form. In addition, the groove provided on the back surface of the face member is formed with a width of 4mm, and is formed by milling with an NC machine. For the impact absorber, an elastomer (polymer mixture) formed by die-casting of a Mitsubishi Chemical Co., Ltd. product name "Wabalong SR04" was used. Additionally, each striking head body is shown in Figure 11 ~ Figure 16 . while embodiment 9 as Figure 17 As shown, a void is provided on the bottom surface of the recess.

Abstract

PROBLEM TO BE SOLVED: To provide a golf club head which can provides an excellent ball hitting feeling by enhancing a shock absorbing property at the time of hitting a ball while suppressing the lowering of repulsive property. SOLUTION: A face member 2 is constituted of a plate like body including a face surface 2A and a face back surface 2B opposite to the same, and a side end surface 2C connecting the face back surface 2B and the face surface 2A. A head body 3 has an opening portion O making the face member 2 freely deform rearward from the head without touching with the face member 2 at the time of hitting a ball, and an annular face attaching portion 4 to which the face member 2 is connected are disposed around the opening portion O. A shock absorbing body 6 of an elastic material is arranged at at least a part between the face attaching portion 4 and the face member 2 and a position that does not intersect with a vertical line N. The shock absorbing body 6 has a longitudinal shape so as to extend along the face attaching portion and has a cross sectional area of 2.5 to 24.0 mm<SP>2< / SP>. COPYRIGHT: (C)2006,JPO&NCIPI

Description

technical field [0001] The present invention relates to a golf club hitting head capable of suppressing a decrease in rebound performance, improving impact absorption at the time of hitting a ball, and obtaining an excellent hitting feeling. Background technique [0002] In recent years, various proposals have been made, for example, iron-type golf club heads in which a ball-hitting face member and a head main body that is separately manufactured from the ball-hitting face member are bonded together. For such a golf club head, titanium or stainless steel alloys with excellent strength and rebound performance are usually used for the face member, and a metal material with a specific gravity larger than that of the face member is used for the head main body. Accordingly, it is possible to manufacture a golf club head having improved rebound performance, a low center of gravity, and a large moment of inertia. The greater the amount of deflection of the face member at the time ...
