Abstract

An iron golf club head comprising a base metal body having a sole portion which latter is continuous with a hosel portion at the heel end of said sole portion. A weight setting block is provided spacedly above said base metal body and being supported in such position by a plurality of spaced apart support members. A vertical space is disposed between the weight setting block and the hosel portion. A step is formed on said base for receiving the base portion of a fiber-reinforced synthetic resin body encasingly covering said support member and thereby conducing to the security of said synthetic resin material in operative position. A fiber-reinforced synthetic resin layer is also provided on the outer surface of the hosel and at the outer surface of the weight setting block. The weight setting block support members may be of various configurations and of relative dimensions.

Claims

1. An iron golf club head comprising a base metal body having a sole portion, there being a hosel portion continuous with said sole portion along the longitudinal direction thereof, a plurality of spaced support members provided on said base metal body, a weight setting block supported by said support members in elevated relation to said sole portion, a fiber-reinforced synthetic resin member encasingly covering the weight setting block and a layer of fiber-reinforced resin synthetic material provided on the outer surface of said covered weight setting block, there being a vertical space disposed between the weight setting block and the hosel portion of the base metal body, the support members defining a plurality of spaces between them through which extend fiber-reinforced synthetic material defining said fiber reinforced synthetic resin member.

2. The iron club head as defined in claim 1, wherein said support members are vertical and the weight setting block is continuous with the base metal body and is joined thereto by means of said vertical support members.

3. The iron club head as defined in claim 1, wherein the weight setting block is continuous with the base metal body and is joined thereto by means of said plurality of support members, said support members being constituted by a plurality of vertical surpport members and a lateral support member.

4. The iron club head as defined in claim 1 wherein the support members have a transverse thickness which is less than a transverse width of the weight setting block where supported by said support members.

5. The iron club head as defined in claim 1 wherein said sole portion includes a step formed longitudinally thereon, said support members bridging said step and said weight setting block.

6. The iron club head as defined in claim 1 wherein said spaces are rectangular.

7. The iron club head as defined in claim 1 wherein said spaces are circular.
