Abstract

A golf putter comprised of a plastic putter head formed about a preselectedly weighted core structure, an elongated shaft having a lower end connected to the putter head, and a grip portion located at an upper opposite end. The upper end of the shaft is suitably counterweighted to provide a weight balance point for the golf putter in proximity to the lower end of a paddle grip portion. The core structure is comprised of a tubular shaped element having weights located in opposite ends thereof, and a filler block located therebetween and including a rod member having an end portion supported by the element and connected at an opposite end to the shaft.

Claims

1. A golf putter including a putter head and an axially extending shaft having a grip portion at the upper end and an inwardly extending passage located at the lower end, said putter head having an upper surface, a sole surface, toe and heel portions and comprising a core structure including a sleeve of generally rectangular shaped cross-section having an upper wall, a lower wall, end portions and two side walls and having an internal passage which extends completely therethrough between said end portions, means for filling said internal passage including a block having a cross-section conforming to the crosssection of said internal passage and located therein, said block being of a light density material, first and second spaced inserts in said internal passage on opposite ends Of said block and corresponding to said end portions of said sleeve, said inserts each being of a preselected weight to provide a predetermined weight to said putter head, said inserts being of substantially greater density than said block, weighting means located in the upper end of said shaft for counter-balancing said predetermined weight of said putter head and providing a weight balance point in proximity to the lower end of said grip portion, said core structure further including a downwardly extending, vertically inclined passage, said inclined passage being located substantially centrally between both said spaced inserts and said side walls of said sleeve and extending through the upper wall of said sleeve and at least partially into said block, a rod formed from a thermally conductive material and having a first end supported in said downwardly extending passage and an opposite end extending outwardly from the upper wall of said sleeve and connectably and telescopically located in said inwardly extending passage formed in said shaft, a plastic shell formed substantially entirely about said core structure and including a neck formation formed on the upper surface of said shell and at least a portion of said rod, said neck formation including a shoulder spaced between said upper surface of said shell and said opposite end of said rod for axially locating said lower end of said shaft relative to said rod, said neck formation and said shaft being located substantially centrally of said head in both a longitudinal and transverse direction, said head being substantially symmetrically configured about the neck, rod and shaft assembly in both a longitudinal and transverse direction, and a resilient striking face connected to at least one side surface of said shell.

2. The putter of claim 1 with said rod member being also constructed from a resilient, deformable material whereby the angle between said putter head and said shaft can be selectedly permanently adjusted.

3. The gof putter, as recited in claim 1 wherein said inserts are a pair of metal castings disposed in opposite ends of said sleeve.

4. The golf putter, as recited in claim 1 wherein said block is formed from a wood material and wherein said block includes an expansion joint.

5. The golf putter, as recited in claim 1 wherein said plastic shell is molded about said core structure and said rod member and with said rod member being made of a material having good heat conductivity, whereby said rod member functions as a heat sink during the molding operation.

6. The golf putter, as recited in claim 1 wherein said resilient striking face is formed from a material having a Rockwell R durometer hardness of approximately 75.

7. The golf putter, as recited in claim 1 wherein said lower end of said shaft is press fitted to said putter head about said rod member.

8. The putter, as recited in claim 1, which includes a flat paddle formation enlarged relative to the cross sectional dimension of said shaft and located at a lower end of said grip portion proximate said weight balance point.
