Abstract

A golf putter head has a central indented concave face portion in which a face plate is either directly formed or installed after it is formed. The face plate has a honeycomb structure with three layers formed from a soft polymer material. The outer or top layer has a honeycomb corrugated construction with equally spaced cells and fits into the cavity of the central portion. The second layer which is similar in configuration to the top layer is immediately beneath the outer layer in abutment there against. The third layer which abuts against the surface of the concave face plate is in the form of a plurality of pins which extend through the cells of the other two layers. Toe and heel portions are removably attached to the opposite sides of the head face portion by means of aligning pins and threaded bolts.

Claims

1. A golf putter head comprising:

a central portion with a first cavity formed in the front part thereof and a second cavity formed in the rear part thereof;

a face plate formed from top and central layers, each having a similar honeycomb structure with equally spaced cells and a third bottom layer having a plurality of pins extending therefrom into the cells of said top and central layers;

said face plate being installed in the first cavity of said central portion;

a toe portion removably attached to one side of said central portion; and

a heel portion removably attached to the side of said central portion opposite said one side thereof.

2. The golf putter head of claim 1 and further including aiming markers formed on the wall of said second cavity.

3. The golf putter head of claim 1 wherein said face plate is fabricated of a polymer material.

4. A golf putter head comprising:

a central portion with a cavity formed in the front thereof; and

a face plate installed in the cavity of said central portion, said face plate being formed from an upper layer having a honeycomb structure with spaced cores formed therein, said upper layer being formed from two similar honeycomb layers which are joined together to form a unitary assembly and a lower layer attached to the wall of said cavity and having a plurality of pins extending upwardly from the surface of said wall through the cores of said honeycomb.

5. A golf putter head comprising:

a central portion with a cavity formed in the front thereof;

a face plate installed in the cavity of said central portion, said face plate being formed from an upper layer having a honeycomb structure with spaced cores formed therein and a lower layer attached to the wall of said cavity and having a plurality of pins extending upwardly from the surface of said wall through the cores of said honeycomb;

a toe portion removably attached to one end of said central portion; and

a heel portion removably attached to the end of said central portion opposite to said one end thereof.
