Benefits of technology

[0007]The present invention is conceived in view of the circumstances and aims at providing a hollow golf club head which generates enhanced feeling of hitting and hitting sound.
[0009]The hollow golf club head of the present invention effectively dampens vibrations of the golf club head resulting from hitting of a golf ball by means of the weight formed from magnesium or a magnesium alloy, and enhanced feeling of hitting and enhanced hitting sound are achieved.

Problems solved by technology

However, as a result of a reduction in the thickness and an increase in the size of the golf club head, vibrations developing in the golf club head when the club head hits a golf ball become greater, which unpreferably affects the feeling of hitting and hitting sound.

Embodiment Construction

[0013]An exemplary embodiment of the present invention will be described in detail below. In the exemplary embodiment, no limitations are imposed on the material of a metal head main body having a hollow section. However, for example, a titanium alloy, stainless steel, an aluminum alloy, and the like, are mentioned. The metal head main body may also be formed integrally by means of casting or connecting a plurality of parts through welding or the like.

[0014]No limitations are imposed on the type of a metal head main body employed in the exemplary embodiment. A light-weight driver head having a small thickness is particularly preferable. For instance, a driver head, which is formed from, e.g., a titanium alloy (of, e.g., a specific gravity of about 4.5) or an aluminum alloy (of, e.g., a specific gravity of about 2.7) and has a head volume of 300 to 500 cc, can be preferably used. In the case of a head formed from stainless steel having large specific gravity (for example, a specific ...

Abstract

A hollow golf club head includes: a metal head main body including a hollow section; and a weight formed from magnesium or a magnesium alloy in at least one of a toe side, a heel side, a back side and a sole of the metal head main body.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a hollow golf club head which generates superior feeling of hitting and a superior hitting sound.[0003]2. Description of the Related Art[0004]A metal golf club head having a hollow section has become larger in size. Of so-called drivers head having a loft angle of 13° or less, a driver head having a head volume of 300 cc or more, particularly 350 cc to 500 cc, has come predominant. In the case of the driver head, a head weight is 200 g or less and preferably ranges from 180 g to 195 g or thereabouts; and the specific gravity of a titanium alloy ranges from 4.2 to 5.0. Hence, a crown, sides, and a sole are made smaller in thickness. In some cases, partially reducing the thickness of a face has hitherto been performed.[0005]In a heretofore driver head which is formed from a titanium alloy (e.g., Ti-6Al-4V) through casting and has a hollow section, each of a crown, a sole, and sides has a t...
