A golf swing position trainer for teaching a golfer to swing a golf club correctly, without involving the striking of a golf ball. This device is constructed of rigid material, with a handle at one end enabling the golfer to grasp the device with both hands and move it in the general manner of a golf club. The handle portion together with an intermediate leg portion form an arcuately shaped portion, with a relatively small U-shaped portion in effect forming a continuation of the intermediate leg portion. The relatively small U-shaped portion is disposed in an orthogonal relationship with the plane of the arcuately shaped portion. A positioning reference in effect forms a continuation of the relatively small U-shaped portion, with this positioning reference pointing away from the handle portion and serving to indicate to the golfer at one part of the swing, the line of sight to the target.
A golf swing position trainer for teaching a golfer to swing a golf club correctly, said position trainer being constructed of rigid material and configured to have a handle portion at one end, enabling the golfer to grasp the handle portion and move the position trainer with both hands in the general manner of a golf club, the part of said position trainer having the handle portion being a component of an arcuately shaped portion, with an intermediate leg portion of said position trainer representing another part of said arcuately shaped portion, a relatively small U-shaped portion in effect forming a continuation of said intermediate leg portion, with said relatively small U-shaped portion disposed in a plane residing in approximately an orthogonal relationship with the plane of said arcuately shaped portion.
A golf swing position trainer for teaching a golfer to swing a golf club correctly, said position trainer being constructed essentially of a single piece of rigid material, said position trainer configured to have a handle portion at one end, enabling the golfer to grasp the handle portion and move the position trainer with both hands in the general manner of a golf club, the part of said position trainer having the handle portion being a component of a relatively large U-shaped portion, with an intermediate leg portion of said position trainer representing another part of the relatively large U-shaped portion, said intermediate leg portion residing in approximately the same plane as said handle portion and disposed approximately 180° away from said handle portion, a second, relatively small U-shaped portion in effect forming a continuation of said intermediate leg portion, with said second, relatively small U-shaped portion disposed in a plane residing in approximately an orthogonal relationship with the plane of said relatively large U-shaped portion, and a positioning reference portion of said position trainer, said positioning reference being relatively short and in effect forming a continuation of said relatively small U-shaped portion, said positioning reference being disposed at approximately a 45° angle to the plane of said relatively small U-shaped portion, said positioning reference forming the opposite end of said position trainer with regard to said handle portion, and pointing away from said handle portion.
A golf swing position trainer for teaching a golfer to swing a golf club correctly, said position trainer being constructed essentially of a single piece of rigid material, said position trainer configured to have first and second ends, with a handle portion formed at said first end, with said handle portion enabling the golfer to grasp the handle portion and move the position trainer with both hands in the general manner of a golf club, said handle portion representing a component of a relatively large U-shaped portion of said position trainer, with an intermediate leg portion of said position trainer representing another part of the relatively large U-shaped portion, said intermediate leg portion residing in approximately the same plane as said handle portion and disposed approximately 180° away from said handle portion, a second, relatively small U-shaped portion in effect forming a continuation of said intermediate leg portion, with said second, relatively small U-shaped portion disposed in a plane residing in approximately an orthogonal relationship with the plane of said relatively large U-shaped portion, said second end of said position trainer representing a positioning reference, said positioning reference being relatively short and in effect forming a continuation of said relatively small U-shaped portion, said positioning reference being disposed at approximately a 45° angle to the plane of said relatively small U-shaped portion and pointing away from said handle portion.

In the past, a number of devices have been proposed for use by golfers, to aid them in developing and improving their swings. Unfortunately, many of the prior art devices concerned with the swing of the club have been expensive to purchase and/or difficult to use. As a consequence, these devices have not gained much favor with a large number of golfers.
The Strahan U.S. Pat. No. 3,351,346 entitled “GOLF SWING TRAINING DEVICE” teaches the use of weighted components on a shaft used for helping a golfer develop his swing. Strahan mentions that it is the goal of his device to provide a golf swing training device for teaching a golfer to perfect an inside-out swing of a golf club, but his device bears little relation to the present invention.
The Pelz U.S. Pat. No. 3,462,155 entitled “GOLF CLUB HAVING MEANS OF ALIGNING RELATIVE TO A USER” is of marginal pertinence to the instant invention inasmuch as it is a putter type device, having a club head equipped with a striking face designed to contact a golf ball, rather than being strictly a training device bearing some degree of relationship to the present invention, by the use of which a ball is not struck.
FIG. 1 is a view showing my novel golf swing position trainer in use by a right handed golfer, with this view illustrating how the positioning reference portion of my device is brought into contact with the biceps muscles of the golfer during the upward part of the backswing;
FIG. 2 is a perspective view of my golf swing position trainer, showing the relative positions of several of the significant bends in a device configured for use by a right handed golfer;
FIG. 3 is a perspective view to a larger scale of the upper portion of my golf swing position trainer, showing in the case of a device configured for a right handed golfer, the relationship of the positioning reference relative to the member by which it is supported;
A golf swing position trainer in accordance with this invention is adapted to train a golfer to swing a golf club correctly, with an exemplary version of my invention being illustrated in FIG. 1, where it has been placed in use by a right handed golfer. As easily seen in this figure as well as in FIG. 2, my position trainer 10 is constructed essentially of a single piece of rigid material, and is configured to have first and second ends. By way of example, I prefer to use an aluminum rod of 6063 aluminum that is ½″ in diameter in constructing my novel device, but I obviously am not to be limited to this. As an alternative, an industrial grade, rigid plastic could be used when cost is a factor.
An important ancillary portion of my device is represented by handle portion 12, which is affixed over the first end of my device. The handle portion is typically molded of non-metallic material, such as industrial grade plastic. The handle portion 12 is carefully configured to enable the golfer to grasp the handle portion in a particular relationship with respect to the remaining portion of the swing position trainer. Upon the handle being grasped correctly with both hands, my novel position trainer can be moved or swung in the manner of a golf club, as generally indicated in FIG. 1 as well as in related FIGS. 6 through 11, but it must be borne in mind that the position trainer is not intended to be brought into direct contact with a golf ball.
It is to be seen from FIG. 2 that the handle portion 12 is affixed to a component of a relatively large U-shaped or arcuately-shaped portion 14 of the position trainer, with an intermediate leg portion 16 of the position trainer representing another important part of the relatively large U-shaped portion 14. The intermediate leg portion 16 resides in approximately the same plane as the handle portion 12 and is disposed somewhat less than 180° away from the handle portion 12. This plane in which the handle portion 12 and the intermediate leg portion 16 reside is shown as plane 20 in FIG. 5.
