DESCRIPTION:
BRIEF SUMMARY
The present invention relates to a training device for assisting in the development of a correct putting stroke for the game of golf. The device can also be used to assist in the development of a correct chip-shot stroke where a golf ball is struck by any golf club, other than a putter, but a full swing is not used. For purposes of brevity the following description will be with reference only to putting strokes however those familiar with the game of golf will appreciate the applicability to chip-shots without any further comment.
Prior art golf training devices have been proposed where a golf club is constrained in a manner so as to follow a fixed path in which the golf club may be swung in a full arc by the training golfer. However it is recognised that the skills required during putting strokes are quite different to those of swinging the golf club for a full swing shot. The prior art training devices developed for full swing shots are therefore not useful in developing the skills required for putting shots.
It is therefore an object of the present invention to provide a golf putting trainer which will ameliorate the disadvantages of prior art by providing a device useful in developing the putting stroke.
DISCLOSURE OF THE INVENTION
Accordingly, in one broad form, the present invention may be said to consist in a golf putting trainer comprising a support structure, a guide track secured by the support structure, a guide track follower adapted to be moved along the guide track following closely the line defined thereby, and a golf club clamp device attached to the guide track follower, wherein a club attached to the club clamp is prevented from pivoting about the longitudinal axis of the club shaft, prevented from linear movement through the club clamp, and free to pivot about the axis proximate the golf track follower in planes containing said guide track and perpendicular thereto.
It is preferred that the guide track is a cylindrical sectioned, semi-rigid rod which is deformable so that it can be set in desired arcuate formations of selected radii.
Preferably the device includes a support plate with indicator marks showing correct ball position, and having the support structure attached thereto.
Preferably the training device further includes a visual guide including a line marked on the base plate and a viewing mark adjustable to be vertically above the line so that by viewing the line superimposed with the viewing mark the golfer's head is positioned vertically above the line of travel of the ball.
BRIEF DESCRIPTION OF THE DRAWINGS
By way of example only, a preferred embodiment will now be described with reference to the following drawings in which:
FIG. 1 is a plan view of a preferred embodiment of the invention;
FIG. 2a is an elevation of a portion of the invention including an end support structure;
FIG. 2b is an end elevation of the portion shown in FIG. 2a;
FIG. 3a is an elevation view of a portion of the device being a guide track follower; and FIG. 3b is a plan view of the guide track follower of FIG. 3a;
FIG. 4a is an end elevation of the device in use;
FIG. 4b is a front elevation of the device in use;
FIG. 5a is a plan view of the base plate of the device; and FIG. 5b is an inverted plan view of the base plate shown in FIG. 5a.
BEST MODE OF CARRYING OUT THE INVENTION
The preferred embodiment of the invention described herein is shown in FIG. 1 and includes a guide rail 2, preferably of steel rod secured at its ends to a rigid frame 5. Frame 5 is attached to a base plate 6 which is adapted to be placed on flat ground in use. Base plate 6 preferably includes structure to prevent slipping of the base plate during use. This structure is not shown but might include spikes integral with the base plate 6 or small holes therethrough which nail-spikes can be inserted and driven into the ground.
A golf club is attached by its shaft 3 to shaft guide 1 which is mounted on the guide rail 2. The shaft guide 1, described in detail later herein, slides along guide rail 2 with club shaft 3 constrai
