Benefits of technology

[0007] I have invented a putter in which adjustments to the weight and centre of gravity of its head can be made quickly and without special tools. Moreover the head has a very simple structure and is very economical to construct. Briefly the putter head of my invention, is symmetrical about a plane of symmetry and includes a toe member having an elongated striking surface oriented normal to the plane of symmetry and to the direction in which the head is adapted to swing. A heel member extends to the rear of the toe member and terminates at a rear surface.

Problems solved by technology

A shortcoming of the Meyer golf head is that it has a complicated structure owing to its internal passages.
As a result, the manufacture of the head is time consuming and expensive.
Adjustment requires a tools and a significant amount of time.

Embodiment Construction

[0018] With reference to FIG. 1, the head of the putter, generally 10 includes a toe member 12 and a heel member 14 which extends from the rear of the toe member. A shaft 20 of a handle extends upwardly from the putter head.

[0019] The toe member has an elongated striking surface 22 on its front wall. The surface is flat and lies on a plane 24. The upper edge 22a of the striking surface is straight while the lower edge 22b has a flat central portion 22c and flat upwardly sloping side edges 22d,e.

[0020] With reference to FIG. 2, the shaft has a longitudinal axis 20a-20a. That axis is parallel to and spaced apart from an imaginary line 26 which, intersects plane 24 of the striking surface. Plane 24 is oriented such that the angle 28 between that plane and line 26 is between 0 degree and about 3 degrees. It will be observed that when the angle is greater than 0 degree, the angle is downwardly opening so that the lower edge 22b of the striking surface is ahead of the upper edge 22a.

Abstract

The putter head is symmetrical about a plane and includes a toe member having an elongated striking surface and a heel member which extends to the rear of the toe member. In one embodiment of the putter head, a cavity extends inward from a rear or upper wall of the heel member. In another embodiment, a nut is attached to the rear or upper wall of the heel member. Plugs of differing weights are each adapted to be screwed into the cavity or into the central opening of the nut.

Description

FIELD OF THE INVENTION [0001] This invention relates to golf clubs and more particularly to the head of a golf putter having provision for altering the overall weight and the distribution of the weight of the putter. BACKGROUND OF THE INVENTION [0002] The weight of the head of a golf club and the location of its centre of gravity are well known to affect a golfer's swing. The weight of the head for example, affects the force of impact of the swing which in turn affects the distance that a ball travels assuming that the ball is hit squarely. The greater the force of impact of the head at the time of impact with the ball, the longer will be the length of a shot, again assuming that the ball is hit squarely. The force of impact is governed by the strength of the player and the weight of the head. For a given player the weight of a head is the governing factor for obtaining the maximum possible distance. [0003] The weight and centre of gravity can be customized at the time of manufactur...
