Wooden club head

Wooden club head description/claims

1. Field of the Invention

The present invention relates to a combination of a golf club head and, more particularly, to a wooden club head having a plurality of components made of steel material to increase the volume of the club head under a preset overall weight limitation of the club head.

2. Description of Related Art

Taiwan Utility Model No. M283662 discloses a large golf club head including a steel body 7, a light cover 8, and a light faceplate 9, as shown in FIG. 1. The steel body 7 is made of metal or alloy with a high specific gravity, such as stainless steel, carbon steel, low-carbon steel, and alloy steel. The light cover 8 and the light faceplate 9 are respectively attached to a top opening 71 and a front opening 72 of the body 7 to form a golf club head. The steel body 7 further has a neck 73 on a side thereof.

The light cover 8 and the light faceplate 9 are made of light, composite plates such as carbon fiber plates and have a specific gravity smaller than 6.0 g/cm3. In assembly, the light cover 8 and the light faceplate 9 are coupled to the openings 71 and 72 by welding, brazing, forcible insertion, or bonding. The light cover 8 and the light faceplate 9 utilizing reinforced material reduce the overall weight of the golf club head so that the overall volume of the golf club head can be relatively increased. Furthermore, the light cover 8 and the light faceplate 9 reduce the weight of the golf club head in the upper portion and the front portion while the steel body 7 increases the weight of the golf club head in the bottom portion and in the rear portion. Thus, the center of gravity of the golf club head can be adjusted downward and rearward to enhance the striking characteristics.

However, the light material of the light cover 8 and the light faceplate 9 is different from the material of the steel body 7 such that the light cover 8 and the light faceplate 9 must be manufactured separately from the steel body 7. Namely, the light components cannot be directly formed on the steel body 7, leading to high manufacturing costs and low assembling tolerance. Furthermore, the golf club head made of different materials has reduced resonance frequency between the materials, adversely affecting the quality of the sound generated during striking.

An object of the present invention is to provide a wooden club head including a plurality of components that are preformed by steel alloy. Each component has a thickness between 0.25 mm and 0.8 mm or between 1.5 mm and 3.0 mm such that the overall volume of the club head can be increased under the preset overall weight limitation.

Another object of the present invention is to provide a wooden club head including a plurality of components each having a specific gravity between 6 g/cm3 and 10 g/cm3 such that the overall volume of the club head can be increased to a range between 380 cc and 500 cc under the preset overall weight limitation.

To achieve the aforementioned objects, the present invention provides a wooden club head including a thin body component and a thin faceplate component. The thin body component has a front engaging opening, a crown, a sidewall, and a sole. The thin faceplate component is coupled with the front engaging opening of the thin body component to form the wooden club head. The thin body component and the thin faceplate component are made of steel alloy having a specific gravity between 6.0 g/cm3 and 10.0 g/cm3. The thin body component has a thickness between 0.25 mm and 0.8 mm, and the thin faceplate component has a thickness between 1.5 mm and 3.0 mm. The wooden club head has an overall volume between 380 cc and 500 cc and an overall weight between 180 g and 220 g.
