Abstract

A putter having a hosel block located on a back surface of a front portion of the putter. The hosel block can be dimensioned and positioned to locate a shaft axis at various locations in a front-to-back direction and in a heel-to-toc direction.

Claims (41)

1 . A putter comprising:

a heel side;

a toe side opposite said heel side;

a front portion;

a rear portion opposite said front portion;

wherein said front portion includes a striking face and a back surface opposite said striking face, said back surface facing said rear portion,

wherein a hosel block is coupled to said back surface of said front portion.

2 . The putter of claim 1 , wherein said hosel block includes a shaft connection portion configured to couple said putter to a shaft having a shaft axis.

3 . The putter of claim 2 , wherein said hosel block has a front surface that contacts said back surface of said front portion,

wherein said shaft axis is located a distance D 1 from said front surface of said hosel block measured in a direction perpendicular to said front surface of said hosel block.

4 . The putter of claim 3 , wherein a center of gravity of said putter is located at a CG depth measured perpendicular to said striking face and rearward from said striking face, and

wherein said CG depth is between 0.20 inches and 1.75 inches.

5 . The putter of claim 4 , wherein said shaft axis is located at a shaft axis depth measured perpendicular to said striking face and rearward from said striking face, and

wherein said hosel block has a distance D 1 which positions said shaft axis depth at said CG depth.

6 . The putter of claim 5 , wherein said shaft axis goes through said center of gravity.

7 . The putter of claim 6 , wherein said shaft axis is toeward of said center of gravity.

8 . The putter of claim 7 , wherein said shaft axis is heelward of said center of gravity.

9 . The putter of claim 5 , further comprising at least one weight member on a bottom portion of said putter.

10 . The putter of claim 2 , wherein said shaft connection portion has a protruding member configured to fit within said shaft.

11 . A putter comprising:

a heel side;

a toe side opposite said heel side;

a front portion;

a rear portion opposite said front portion;

a striking face located on said front portion; and

a hosel block having a shaft connection portion configured to couple said putter to a shaft having a shaft axis,

wherein said shaft axis is located at a shaft axis depth measured perpendicular to said striking face and rearward from said striking face,

wherein a center of gravity of said putter is located at a CG depth measured perpendicular to said striking face and rearward from said striking face, and

wherein said shaft axis depth is equal to said CG depth.

12 . The putter of claim 11 , wherein said shaft axis goes through said center of gravity.

13 . The putter of claim 11 , wherein said shaft axis is toeward of said center of gravity.

14 . The putter of claim 11 , wherein said shaft axis is heelward of said center of gravity.

15 . The putter of claim 11 , wherein said CG depth is between 0.20 inches and 1.75 inches.

16 . The putter of claim 11 , wherein said front portion includes a back surface opposite said striking face, said back surface facing said rear portion,

wherein said hosel block is coupled to said back surface of said front portion.

17 . The putter of claim 16 , wherein said hosel block has a front surface that contacts said back surface of said front portion.

18 . The putter of claim 17 , wherein said front portion includes a face insert on said striking face, and

wherein said face insert is secured within a front pocket of said front portion.

19 . The putter of claim 18 , wherein said hosel block further comprises a protruding member extending forward from said front surface of said hosel block in a direction perpendicular to said front surface of said hosel block.

20 . The putter of claim 19 , wherein said front portion includes a recess formed between said back surface of said front portion and said front pocket, and

wherein said protruding member is secured within said recess.
