Abstract

A golf club putter having a low head center of gravity and a high MOI is disclosed herein. The putter has a metal body comprising a face and a hosel, a low density dampening layer affixed to the body, and a high density rear weight affixed to the dampening layer, and the dampening layer has a first surface that forms an angle with an opposing second surface that is inversely proportional to the distance of the hosel from a heel side of the body.

Claims (37)

1. A putter comprising:

a body comprising a face and a hosel;

a dampening layer comprising a first front surface and a first rear surface; and

a rear weight comprising a first contact point disposed on a heel side of the rear weight, a second contact point disposed on a toe side of the rear weight, and a recess sized to receive at least a portion of the dampening layer,

wherein the face comprises a striking surface and a second rear surface,

wherein the dampening layer is affixed to the second rear surface,

wherein at least a portion of the dampening layer is disposed within the recess and is affixed to the rear weight,

wherein the rear weight connects with the body at the first and second contact points,

wherein the first front surface is not parallel with the first rear surface, and

wherein an angle created by the first front surface with respect to the first rear surface is inversely proportional to the distance between the hosel and a heel side or a toe side of the putter body.

2. The putter of claim 1 , wherein the dampening layer is composed of urethane.

3. The putter of claim 1 , wherein the rear weight is composed of a high density metal alloy.

4. The putter of claim 1 , wherein the rear weight comprises tungsten.

5. The putter of claim 1 , wherein the body is composed of carbon steel.

6. The putter of claim 1 , wherein the body and the rear weight each have a dark color, and wherein the dampening layer has a light color.

7. The putter of claim 6 , wherein the dark color is black, and wherein the light color is white.

8. The putter of claim 1 , wherein the striking surface comprises a textured pattern.

9. The putter of claim 8 , wherein the textured pattern is machined into the striking surface.

10. The putter of claim 1 , wherein the putter has a moment of inertia of no less than 3200 g-cm 2 and no more than 5500 g-cm 2 .

11. The putter of claim 1 , wherein a portion of the dampening layer has an approximately triangular shape.

12. The putter of claim 1 , wherein the striking surface is disposed on a face insert, and wherein the face insert is disposed within a recess in the face.

13. The putter of claim 1 , wherein the rear weight comprises a second front surface and a third rear surface, and wherein the second front surface is not parallel with the third rear surface.

14. A putter comprising:

a steel body comprising a face, a rear side, a heel side, a toe side, and a hosel disposed proximate the heel side;

a urethane dampening layer comprising a first surface and a second surface; and

a tungsten alloy rear weight comprising a first contact point disposed on a heel side of the rear weight, a second contact point disposed on a toe side of the rear weight, a third surface, and a fourth surface,

wherein the face comprises a first recess sized to receive a face insert,

wherein the first surface is affixed to the rear side,

wherein the third surface is affixed to the second surface,

wherein the rear weight comprises a second recess sized to receive at least a portion of the dampening layer,

wherein the rear weight connects with the body at the first and second contact points,

wherein the first surface forms a first angle with the second surface,

wherein the third surface forms a second angle with the fourth surface, and

wherein the first angle and the second angle add up to 90°.

15. The putter of claim 14 , wherein the first angle is no less than 1° and no greater than 45°.

16. The putter of claim 14 , wherein the dampening layer and the rear weight are removably affixed to the body with one or more fasteners.

17. The putter of claim 14 , wherein the dampening layer and the rear weight are permanently affixed to the body.
