Abstract

A golf wooden club head comprises a casing, a bottom plate, a base plate, a support layer and a ball-striking plate. The hollow casing is provided with an opening and a shoulder which is provided with a ring-shaped shoulder surface coplanar with one surface of the shoulder and facing outwards. The shoulder is further provided with a rib having a surface which is facing outwards and coplanar with the shoulder surface. A receiving space is formed between the shoulder surface and the front surface open end. The bottom opening is sealed off with the bottom plate. The base plate is disposed in the shoulder surface for separating the receiving space from interior space of the casing. The support layer is disposed in the receiving space such that the support layer is formed integrally with the ball-striking plate.

Claims

1. A golf wooden club head comprising:

a casing of a hollow construction and provided in a bottom surface thereof with an opening and further provided with a recessed front surface in communication with an interior space of said casing having an inner wall provided with a shoulder which is located a predetermined distance from a front surface open end and which extends around the edge of said open end, said shoulder having a ring-shaped shoulder surface which is provided with at least a rib portion having a surface which faces outwards and is coplanar with said shoulder surface, said front surface open end forming a receiving space in conjunction with said shoulder surface;

a bottom plate fastened to said bottom surface of said casing such that said opening of said bottom surface is sealed off by said bottom plate;

a base plate fastened to said shoulder surface for separating said receiving space from said interior space of said casing so as to make said interior space airtight and to make said receiving space a recessed slot;

a support layer made of a bulk molding compound of a fiber-reinforced resin material, said support layer forming a part of a ball-striking surface of a golf wooded club head by being hardened in said recessed slot under heat and pressure; and

a ball-striking plate pre-arranged on said bulk molding compound and made integrally with said support layer for forming said ball-striking surface of said wooden club head;

wherein said shoulder of said casing is provided with at least two projections extending outwards and perpendicular to said shoulder surface; and

wherein said ball-striking plate is provided with at least two holes corresponding in location to and engageable with said two projections.
