Abstract

A Golf club has marks or an attached device or both to enable the player to gauge more accurately its positioning relative to the ball, the ground and the player and the angle of the club and club head by using the principles of parallax. Indicators, protuberances, notches, dots or marks at two or more relative alignments may be employed. <IMAGE>

Description

SPECIFICATION Parallax Golf-club This invention relates to a golf club design that enables the club to be positioned accurately and consistently by an application of the principle of parallax.

This invention consists of marks of any description engraved on or affixed to a golf club.

The only necessary feature is that the marks should be on two or more horizontal planes on the shaft or head of the club. Provided that the marks are suitably situated they can be used as a sight to detect a deviation from a predetermined relationship which the golfer has found to be optimal in making a stroke.

The relationship between the higher and lower marks controls the angle of the shaft of the club in relation to the ground and accordingly (the length of the shaft being constant) the distance of the player from the club head. This relationship is explained diagrammatically in Drawing A.

In addition, the invention controls the angle of the club head in relation to the ground. This enables the player to choose which part of the club head is used to strike the ball. Some players prefer two hit the ball with the heel of the club while others preferto use the toe (see Diagram B).

The principle of the invention can accommodate an infinite variety of golfing styles thereby permitting the golfer to continue adopting the stance which he finds most comfortable at the same time as ensuring that he addresses the ball consistently. A series of marks on the lower plane can effectively calibrate the relationships and determine the effect of variations in the golfer's stance on the shot played.

The principle detects changes in the positional relationship between the golfer and the ball and between the horizontal axis of the club head and the ground. There are a number of possible ways of incorporating this invention into any golf club. For descriptive purposes only, drawings Nos. 1, 2, 3, show how the invention could be incorporated into a putter and a wooden club. Although the drawings do not illustrate it as an alternative, it is intended that the patent should include markers attached to the shaft as weil as to the head of any club of any type. A specific embodiment of the invention will now be described by way of example with reference to the accompanying drawing No. 1/3. This is an example showing a method of applying the principle to a putter: Figure 1.Shows in perspective the putter head viewed from the toe of the putter with the application of one mark on the top surface and three marks on a lower surface.

Figure 2. Shows the view the player will get looking down the shaft of the club as he addresses and plays the ball.

With the use of these marks the player will be able to gauge by eye the angle of the club head to himself and provided he holds the club in the same manner each time with a similar stance he will also be able to gauge the distance between his feet and the club head and consequently the ball. This is one of the primary areas in which sights could be used to great effect it is envisaged that a golfer will come to know the best relative position of one mark against another to give the best result for him individually and be able to repeat this by repeating the same alignment of marks.

It is not intended that the user of this invention need be restricted to one line and three lines as shown in the example. Marks could be made in any number of ways with protruberances dots notches and so on. Neither is it intended to be restricted to the angle of toe to heel on the golf club.

As an example on drawing No. 2/3, Figures 1 and 2 show the addition of one bump at the top of the toe surface and three at the bottom of the surface, and the view the player would get looking down the length of the shaft aligning these marks.

This example shows how the invention would assist in adjusting the angle of the leading edge vertically in relation to the ground, the ball and player.

Reference Drawing 3/3: Fig. 3 shows a perspex block glued to the putter with sights marked on the top and bottom faces of the perspex for alignment.

Fig. 4 shows an indicator (A) mounted to the shaft with the grid for alignment (B) on the face of the club.

Figure 5 shows notches for alignment on the top and bottom edges of an iron.

Figure 6 shows a transparent perspex driver with cross-sight on the top surface and a grid for alignment on a lower plane in the perspex.

Figure 7 shows an indicator cast in the top surface and a grid for alignment on the lower surface.

Most of these would enable the player to align in any direction the tilt and positioning of the club with accuracy.

The invention covers almost any method of measuring the angle of the club and its positioning with regard to the player the ground and the ball, by the gauging of the relationship of marks or points on different levels, employing the principles of parallax.
