Abstract

A putter head having variable face thickness or multiple materials and adjustable weighting features is disclosed herein. The variable face thickness may comprise a plurality of geometric shapes on the striking face surface with spacing between them that decreases in a top to bottom direction, or the face may include a plurality of angled carbon rods. The putter also includes an adjustable weight cartridge that can pivot in a toe-heel direction.

First claim

We claim:

1. A putter head comprising:
a body comprising a top portion, a bottom portion, a heel side, a toe side, a front recess, and a hosel; and
a face insert comprising a striking surface, a rear surface, a plurality of carbon rods, and a secondary material,
wherein the face insert is sized to fit within the front recess,
wherein the secondary material is different from the material of the carbon rods,
wherein each of the plurality of carbon rods has a first end proximate the striking surface and a second end proximate a rear surface opposite the striking surface,
wherein each of the plurality of carbon rods is angled with respect to a horizontal plane extending perpendicular to the striking surface,
wherein the plurality of carbon rods comprises a first set of carbon rods and a second set of carbon rods,
wherein the first set of carbon rods is disposed at a first angle with respect to the horizontal plane,
wherein the second set of carbon rods is disposed at a second angle with respect to the horizontal plane, and
wherein the first angle is different from the second angle.

2. The putter head of claim 1 , wherein the first end of each of the plurality of carbon rods is closer to the bottom portion than the second end of each of the plurality of carbon rods.

3. The putter head of claim 1 , wherein each of the first set of carbon rods is angled at 45 degrees with respect to the horizontal plane.

4. The putter head of claim 1 , wherein the secondary material comprises urethane.

5. The putter head of claim 1 , wherein the body is composed of a metal material.

6. The putter head of claim 5 , wherein the metal material is a stainless steel.

7. The putter head of claim 1 , wherein the body comprises a plurality of weight ports sized to receive one or more weight screws.

8. A putter head comprising:
a body comprising a top portion, a bottom portion, and a face portion; and
an adjustable weight cartridge comprising a heavy end, a lightweight end, a first through hole disposed in the heavy end, and a second through hole disposed in the lightweight end,
wherein the bottom portion extends rearwards from the face portion by at least one inch,
wherein a pin extends upwards from a rear portion of the bottom portion, and
wherein each of the first and second through holes is sized to receive the pin and allow the adjustable weight cartridge to rotate in a heel-to-toe direction around the pin.

9. The putter head of claim 8 , wherein when the pin is engaged with one of the first and second through holes, an opposite end of the adjustable weight cartridge is disposed proximate a rear surface of the face portion.

10. The putter head of claim 9 , wherein the opposite end of the adjustable weight cartridge makes contact with a rear surface of the face portion.

11. The putter head of claim 8 , wherein the body further comprises a support structure, and wherein at least one end of the adjustable weight cartridge is capable of making contact with the support structure when the pin is engaged with one of the first and second through holes.

12. The putter head of claim 8 , wherein when the pin is engaged with one of the first and second through holes, the adjustable weight cartridge has a longitudinal axis that is angled with respect to a horizontal ground plane.
