Adjustable putter

Abstract

A golf putter comprises latitudinally elongated head having a generally rectangular hitting face against a golf ball. The head has an integral center plate extending longitudinally and rearward from the hitting face at its bottom. The center plate has a visible centerline for aiming at the ball. A ball joint for angularly fixing a shaft to the head includes a frictional sphere attached to the bottom end of the shaft. A truncated spherical socket is formed by a middle section of the head and a clamp member screw fastened to the head, whereby the shaft is locked in a truncated spherical interior wall at an adjusted angle to the head. Two swappable posts extend from the opposite side of the hitting face of the head near its latitudinal edges, each post having a centrally threaded bore and being threadedly attached to the head so that it may be replaced by a body of varying weight for plugging a void created by the threading of the post.

Description

BACKGROUND OF THE INVENTION[0001]A. Field of the Invention[0002]The present invention relates to golf putters, and more particularly, an adjustable putter for its weighting, lie, loft, grip rotation right or left.[0003]B. Description of the Prior Art[0004]Golf putter is used for short strokes of a ball into a hall cup to complete a hole. This precision instrument of golf club generally consists of a grip, a shaft and a head. The head of the putter is normally designed to have a perpendicular clubface to the playing ground without a significant loft to give the ball a special trajectory.[0005]There are correct methods of using the putter with calm wrists and arms, which in unity should make a pendulum motion sideways resulting in the ball rolling over a distance determined by the gripping force of the hands and the extent of a back swing. Specifically for short putting, wrist or fingers should not be involved in controlling forces to the ball to get the best result. With the well kno...

AI Technical Summary

Benefits of technology

[0018]Two swappable posts extend from the opposite side of the hitting face of the head near its latitudinal edges, each post having a centrally threaded bore and being threadedly attached to the head so that it may be replaced by a body of varying weight for plugging a void created by the threading of the post. Two sets of longitudinal stacks of weight elements having incremental thickness are screw fastened to the head selectively through the threaded bore of the posts respectively to provide a first mode of expanded weight distribution or through the clamp member to provide a second mode of compacted weight positioning in a conventional putter head contour. The weight elements may be selectively added or deleted to adjust the weight of the putter locally in a plane parallel to the center plate and at least one elastic washer is inserted between adjacent ones of the weight elements in each set concentrically thereto to provide a bounce to the putter.

[0020]Acute edges are formed along the boundaries of the semi-spherical recesses and semi-circular top openings of both the head and clamp member to bite the frictional sphere of the shaft in the ball joint locally to enhance the clamping speed as well as clamping force.

[0022]The copper stabilization weights are stackable and removable to adjust overall putter head weight and head balance as well as being able to adjust impact feel from firm to soft using a simple tool of a hex driver. With its adjustable geometry, weight, balance, and feel, the present putter allows the golfer to make adjustment to suit personal preferences. The putter is so adaptable that it complements the golfer's own natural way of stroke instead of compromising each unique stroke to fit otherwise less adaptable putters.

[0025]The putter has a higher moment of inertia (MOI) than most existing putter available to provide an extreme stability and a big and forgiving sweet spot.

Problems solved by technology

As the above patents indicate, known putters are still short of providing a comprehensive range of customizing with putter weight adjustments, loft adjustments, and / or bounce adjustments in an easy structure to make and use intuitively.
