Abstract

A putter includes a shaft, a head having a front face for striking a golf ball and a rear face, and a connector interconnecting the shaft and the head. The connector has a rear edge that can be aligned visually with the rear face of the head by a golfer holding the shaft. The putter head has a toe and a heel, the heel being the end portion of the head that is closer to the golfer when putting and the toe being the end portion of the head that is remote from the golfer when putting. The shaft of the putter is connected to the head of the putter at or adjacent the “toe” end of the head of the putter. This allows a golfer to be able to obtain an accurate visual sighting by looking at that part of the head of the putter that is furthest from him.

Description

BACKGROUND OF THE INVENTION

This invention relates to putters, i.e., to a golf club used for putting. In order for a golfer to putt accurately, the striking face of the putter must be positioned correctly, and it is accordingly an object of the present invention to provide an improved form of putter, the design of which is such as to facilitate accurate putting.

SUMMARY OF THE INVENTION

According to the present invention, there is provided a putter that includes a shaft, a head having a front face for striking a golf ball and a rear face, and a connector interconnecting the shaft and the head, and in which the connector has a rear edge that can be aligned visually with the rear face of the head by a golfer holding the shaft.

The putter head has a toe and a heel, the heel being the end portion of the head that is closer to the golfer when putting and the toe being the end portion of the head that is remote from the golfer when putting. With a conventional putter, the connection to the shaft is at the heel end of the head whereas, with a putter in accordance with the present invention, the connection to the shaft is at the toe end of the head.

The connector interconnecting the head and the shaft is preferably formed as an injection molding integrally with a part of the head of the putter. The injection molding may be of a graphite-reinforced thermoplastic material.

The head of the putter is accordingly preferably formed as two parts, one of which parts provides the striking face of the putter, while the other part is formed integrally with the connector. Said other part preferably provides the upper portion of the rear face of the head.

Said one part of the head of the putter is preferably formed a metal casting so that the head of the putter is of the required weight while, at the same time, the two parts of the head of the putter have contrasting visual appearances facilitating alignment of the rear face of the head of the putter with the rear edge of the connector.

Said one part of the head of the putter is preferably releasably attached to the other part of the head of the putter, and a golfer is preferably provided with a plurality of different forms of said one part of the head. Thus, if the golfer is playing on a warm dry day, he may employ a part which is lighter in weight than the part he would use when the greens are damp.

Various objects and advantages of this invention will become apparent to those skilled in the art from the following detailed description of the preferred embodiment, when read in light of the accompanying drawings.

BRIEF DESCRIPTION OF THE DRAWINGS

FIG. 1 is a rear perspective view of the lower portion of a golf putter. [0009]
FIG. 2 is a side view of the lower portion of the putter. [0010]
FIG. 3 is an exploded rear perspective view of the lower portion of the putter. [0011]
FIG. 4 is an exploded side view of the lower portion of the putter.[0012]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

As shown in the drawings, a golf putter comprises a [0013] shaft 10 that is provided on its upper end with a hand-grip formation (not shown). At the lower end of the shaft 10, there is a plastic injection molding 11 which is preferably formed from a thermoplastic material impregnated with graphite fibers so that the molding 11 will have the required strength and flexibility characteristics.
The [0014] plastics molding 11 includes an upper portion 12 that is connected to the lower end of the shaft 10, a crank portion 13, a main body portion 14, and a lowermost portion 15 that forms part of the head 16 of the putter. The main body portion 14 is inclined relative to and offset from the axis of the shaft 10 of the putter, and the rear edge of the main body portion 14 cooperates with the rear face of the head 16 of the putter to provide a sighting aid.
Thus, when the golfer takes hold of the putter and looks down on the rear face of the [0015] head 16 of the putter along the line Z-Z, the head 16 of the putter will be correctly positioned, to enable the golfer to putt accurately, when the rear edge of the main body portion 14 is in line with the rear face of the head 16 of the putter.
The [0016] head 16 of the putter also includes a metal casting 17 that is secured by threaded fasteners 18 and 19 to the lowermost portion 15 of the plastic molding 11. The metal casting 17 has a flat face 20 for striking the golf ball and is of a color that contrasts with the color of the plastics molding 11. The plastics molding 11 will typically be black in color, while the metal casting 17 can be of steel or brass. The shape of the metal casting 17 is such as to provide a pocket or cavity 21 within which the lowermost portion 15 of the plastics molding 11 is a close fit.
The [0017] metal casting 17 provides the majority of the weight of the head 16 of the putter. A golfer may, however, wish to vary the weight of the head of the putter in dependence on the conditions of the greens on which he is putting. For dry, fast greens, he may prefer a head which is light in weight, whereas, for damp conditions, he may prefer a heavier head. The putter can accordingly be provided with a number of metal castings 17 of different weights, each having a pocket or cavity 21 of the same configuration to receive the lowermost portion 15 of the plastics molding 11.
The head of a putter has two ends, i.e. the “heel” end which is closer to the feet of the golfer when he is putting and a “toe” end which is remote from the feet of the golfer. In a conventional putter, the shaft is connected to the head of the putter at or adjacent the “heel” end of the head of the putter. With, however, the putter of the present invention, the connection to the [0018] stem 10 is at the “toe” end of the head 16 of the putter. The golfer will thus be able to obtain an accurate visual sighting in that he will be able to look at that part of the head 16 of the putter that is furthest from him. He will be able to line up the rear edge of the black main body portion 14 of the plastic molding 11 with the rear face of the head 16 of the putter, which rear face is of two contrasting colors.
As shown in FIG. 2, the configuration of the [0019] crank portion 13 of the plastics molding 11 is such as to provide the required off-setting of the rear edge of the main body portion 14 from the axis of the shaft 10 so that the golfer can clearly see the upper portion of the rear face of the head 16. FIG. 2 also shows that the front face 20 of the head 16 of the putter is at a small acute angle to the vertical.
In accordance with the provisions of the patent statutes, the principle and mode of operation of this invention have been explained and illustrated in its preferred embodiment. However, it must be understood that this invention may be practiced otherwise than as specifically explained and illustrated without departing from its spirit or scope. [0020]
