Abstract

In a golf club for putting, the head of the club comprises a face plate having a hitting surface extending between opposite toe and heel sides of the head and a back surface extending substantially in parallel to the hitting surface. A pair of spaced rod-like bodies are fixed to the back surface of the face plate at the toe and heel sides of the head, respectively, and extend backward and in a direction perpendicular to the hitting surface of the face plate. A shaft-mounting body, for mounting the shaft thereon, is fixedly disposed between the rod-like bodies. A hosel member is attached to the top surface of said shaft-mounting body substantially at a center of the head, the hosel member extends upwardly from the shaft-mounting body to a position near a plane containing the face plate and is connected to the shaft at that position.

Claims

1. A golf club having a head and a shaft, said head comprising:

a thin face plate having a generally flat hitting surface extending between toe and heel sides of said head and a generally flat back surface extending substantially in parallel to said hitting surface;

a pair of cylindrical bodies each having one end thereof fixed to said back surface of said face plate such that one of said pairs is fixed at a position adjacent to said toe side and the other is fixed at a position adjacent to said heel side of said face plate, said pair of cylindrical bodies extending backward in a direction perpendicular to said hitting surface of said face plate with a clearance between said pair of cylindrical bodies;

a shaft-mounting body disposed between said pair of cylindrical bodies and fixed to at least one of said face plate and said pair of said cylindrical bodies such that a center of gravity of said head is in said shaft-mounting body; and

a hosel member attached to said shaft-mounting body, said hosel member including a first portion extending upwardly from said shaft-mounting body, a second portion extending further upwardly from said first portion at a first angle with respect to said shaft-mounting body to a position near a plane containing said face plate and third portion being bent from said second portion at a second angle greater than said first angle, said second portion being connected to said shaft in a manner such that the axis of said shaft passes in front of said center of gravity of said head.

2. A golf club according to claim 1, wherein said shaft-mounting body is fixed solely to said pair of cylindrical bodies and spaced form said back surface of said face plate leaving a clearance therebetween.

3. A golf club according to claim 1, wherein said shaft-mounting body is fixed to said pair of cylindrical bodies and said back surface of said face plate.

4. A golf club according to claim 3, wherein said shaft-mounting body extends in parallel to said pair of cylindrical bodies and has a length greater than those of said pair of cylindrical bodies.

5. A golf club according to claim 1, wherein said shaft-mounting body is fixed to said back surface of said face plate and spaced from said pair of cylindrical bodies.

6. A golf club according to any one of preceding claims 1 to 5, wherein said shaft-mounting body extends in parallel to said pair of cylindrical bodies and has a length less than those of said pair of cylindrical bodies.
