Composite putter head

Abstract

The golf putter head of the present invention is made of a uniform mixture of a base and a filler. The filler is chosen from materials with a high density such as metals, while the base is selected from low density materials such as plastics. The blend of the base and the filler into a uniform composite produces a putter head of unique feel and characteristics. The preferred filler for the composite is metal which adds weight and density to the total material. The metal added ranges from 50 to 95 percent by weight, depending upon the particular plastic and metal combined to achieve the desired results. The blend of metal and plastic provides a composite which is light enough to swing easily with enough weight to give a balanced feel to the putter head and furthermore, the resiliency of the material provides a good reliable response when striking a golf ball. The uniformity of the composition obviates a plastic-metal interface which can separate or mesh incorrectly leading to an inconsistent feel.

What is claimed is:  
     
         1 . A golf club putter comprising a shaft with a grip at a first end and a putter head at a second end, said putter head comprising a composite material including a plastic base with a uniformly blended metal dispersed therein, said metal comprising at least fifty percent by weight of said composite material.  
     
     
         2 . The golf club putter of  claim 1  wherein said metal is selected from aluminum, barium, copper, iron, nickel, lead, stainless steel, and zinc.  
     
     
         3 . The golf club putter of  claim 1  wherein said plastic base is selected from ethylene vinyl acetate, polyurethane, polyolefin, polypropylene, and polyvinylchloride.  
     
     
         4 . A golf club putter head comprising a composite material including a plastic base with a uniformly blended metal dispersed therein, said metal comprising at least fifty percent by weight of said composite material.  
     
     
         5 . The golf club putter head of  claim 4  wherein said metal is selected from aluminum, barium, copper, iron, nickel, lead, stainless steel, and zinc.  
     
     
         6 . The golf club putter head of  claim 4  wherein said plastic base is selected from ethylene vinyl acetate, polyurethane, polyolefin, polypropylene, and polyvinylchloride.  
     
     
         7 . The golf club putter head of  claim 4  wherein a hardness of said putter head is at least Shore A85.  
     
     
         8 . The golf club putter head of  claim 4  wherein said plastic base is a thermal setting plastic.  
     
     
         9 . The golf club putter head of  claim 4  wherein a ratio of said metal filler to said plastic base is between 50 and 95 percent by weight.
