Golf putter head

Abstract

An adjustable heel and toe weighted putter head comprising of stand-alone heel and toe weight-carrying portions spaced rearward from the face portion for increased moment of inertia and also transversely spaced apart from each other by the width of a golf ball to therein define an alignment channel. Each weight-carrying portion consists of a through bore parallel to said face portion, a through threaded insert permanently secured in said bore, selectable weight member(s) housed in said insert, and end plug setscrews that book-end and removably secure said weight member(s) to therein provide for selectable total weight and longitudinal positioning of the center of gravity. The integration of the weight system and the alignment system provides for simultaneous tangential target alignment and parallax golfer head alignment. Positive sloped truncated conical projections on the putter face help minimize ball skid, maximize tactile properties, and provide enhanced audio feedback.

Description

REFERENCE TO RELATED APPLICATION[0001]This non-provisional patent application is based upon U.S. Provisional Patent Application Ser. No. 60 / 791,995 filed Apr. 14, 2006 and hereby claims the benefit of the filing date thereof.BACKGROUND OF THE INVENTION[0002]The present invention is related to golf equipment and, in particular, to a golf putter head with enhanced weight distribution, selectable weights, movable center of gravity, target and address alignment aids, and ball hitting projections that enhance feel, acoustics and ball anti-skid properties.[0003]Heretofore, golf putter heads with adjustable weight members often included extraneous parts such as spacers, springs, magnets, fillers and the like that immobilized weight members in a single longitudinal bore. Other designs included multiple threaded bores which received selectable weights but did not provide infinite adjustability of the center of gravity. A non-bore design often utilized a channel or a cavity within which resid...

AI Technical Summary

Benefits of technology

[0007]It is the objects of the present invention to provide an improved golf putter that provides for forgiveness on miss hits, provides for a simple system to select and adjust weight members, provides references for target and golfer address alignment, and provides for an enhancement in feel and golfer confidence. Accordingly, the objective of a more forgiving putter entails a greater moment of inertia and that is accomplished by dense heel and toe weight members spaced rearward from the face portion. The objective to provide a simple adjustable weight system is accomplished by having selectable dense weight members housed in a chamber movably securable with end plug setscrews, and without the need for spacers, springs, and fillers. The objective of easy target alignment is accomplished by the stand-alone spaced weight-carrying portions defining a ball-width alignment channel wherein said channel is disposed with parallel markings for tangential alignment with the golf ball, or in an alternate embodiment, alignment is provided by an optically isolated alignment disk that has no visible support member and therein becomes a “virtual” golf ball. The objective of repeatable heel-to-toe, here forth called longitudinal, golfer head alignment is accomplished by the parallax properties of the inboard vertical sides of the alignment channel. Correspondingly, the objective of repeatable target-to-putter head, here forth called lateral, golfer head alignment is accomplished by the visible part line on the surface of the weight-carrying portions wherein said part line is located at the inflexion point defined by a vertical tangent. The objective of enhanced feel is accomplished by the sensing of the spaced weight members by using a thin sole section that connects the face portion to the spaced weight-carrying portions, by the isolated face portion, and by the enhanced audible feedback of a struck ball due to the small dense face projections. The objective of increased confidence is accomplished by the customization of the adjustable weights, easy alignment, and an aesthetically functional putter head.

Problems solved by technology

Other designs included multiple threaded bores which received selectable weights but did not provide infinite adjustability of the center of gravity.

The distracting support member makes it more difficult for the various alignment aids to simulate a freestanding golf ball.
