BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates to golf practice equipment. More specifically it relates to controlling the backswing and downswing of the golfer, without the golf club being attached or sliding as well as allowing the golfer to strike golf balls.
2. Description of the Prior Art
Various prior devices have been suggested to control the path of the club head on the backswing, downswing and follow through in the golf swing. These devices generally fall in the following categories:
Golf shaft gliding on the outward part of a tubular PVC pipe whereas prior art U.S. Pat. Nos. 6,322,456, 6,273,826, 5,441,275, 4,928,974, 4,040,633 relates to this application. While most of these devices were generally designed for practice purposes only (not for striking the golf ball), they are still fundamentally flawed. All these prior art devices employ flat backswing and downswing planes which is flawed. For striking a golf ball these devices are also unsuitable because the golfer must be free of any interference whilst these devices suggest sliding of the golf shaft. If mistakes are made during the downswing (not sliding on the pvc pipe) it can lead to various injuries or damage of the golf shaft.
Club head sliding on inward part of flat plane whereas prior art U.S. Pat. No. 6,165,079 relates to this application. The same flaws as discussed above apply.
Golf shaft attached to flat plane or attached to guiding arm whereas U.S. Pat. Nos. 5,595,545, 5,429,367, 5,330,192, 5,421,579, 5,072,942, 5,538,251, 5,301,948, 5,188,367 relate to this application. All of these devices employ flat swing planes and any device that attaches the golf club is not suitable for striking golf balls.
Hands follow flat plane for backswing purposes, whereas prior art U.S. Pat. No. 4,815,743 relates to this application. Apart from the same flaws as discussed above the device also claims a means of keeping the head still during the swing. Hundreds of studies of top professional golfers revealed that the head moves in various ways during the backswing and downswing, suggesting the application to be flawed.
SUMMARY OF THE PRESENT INVENTION
It is the object of this invention to provide a golf training device that guides the golfer during the backswing and downswing, without the golf club being attached or sliding, while at the same time allowing the golfer to strike golf balls.
The device embraces the principle that movement go where there is least resistance and is designed in such a manner that when a successful swing is performed, no part of the training device would have been touched by the golfer at any stage during the entire golf swing.
Further objectives of the invention is safety. The training aid is designed in such a way that even when mistakes are made, the golfer cannot be injured or impart damage to the golf club.
Furthermore the invention overcame all prior art swing plane flaws, by using a uniquely designed guiding surface that is not only c-shaped, but it also continuously curves inwards away from a vertical extending axis. The reason for this design is that a successful downswing and golf shot can only be achieved, if the hands travel in a continuously curved shape from a front on as well as a side on view in the downswing.
It is also the purpose of this invention to provide a means of establishing the correct relationship of the clubface and the club shaft to the guiding surface at any point during the backswing or downswing. To achieve this the guiding surface not only curves continuously away from a vertically extending axis, but at a certain point in the downswing the lowest end of the guiding surface also begin to twist or rotate inward. In order for the golfer to follow the guiding surface, a v-shaped member that attaches to the golf shaft is provided with a planar surface at the end of one v. This planar surface is then used by the golfer to be moved along the guiding surface at a predetermined distance without touching the guiding surface and at the same time keeping the planar surface both horizontally and vertically square to the guiding surface. This v-shaped attachment also serves to protect the golfer's hands and ensuring that the left arm does not contact the guiding surface during the backswing or downswing
A further objective of the invention is to control the movement of the shaft of the golf club. A downwardly extending elongated padded tubular member is mounted towards the bottom of the surface opposing the guiding surface, complete with a rotational bearing and a force releasing mechanism to set the tubular member at a desired angle. If during any part of the downswing the shaft of the golf club is projected outside the desired path of movement, the padded tubular member will be struck and projected around its axis, indicating the wrong move.
