Golf swing trainer

DETAILED DESCRIPTION The invention provides a golf swing trainer for use by a developing golfer.
The trainer includes a rotor that rotates about a rotational axis.
When using the trainer, the golfer connects himself or the golf club shaft to the rotor at a point near his hands.
The golfer then takes practice swings while linked to the rotor.
According to one aspect of the invention, the rotor is flexible so that deviations in the golfer's swing from the ideal path causes flexure of the rotor.
This in turn causes noticeable flexure and vibration in the rotor, which clearly indicates the error to the golfer so that he may correct his motion on subsequent swings.
According to another aspect of the invention, the rotational inertia of the rotor about the axis is less, and in preferred embodiments much less, than that of the swung club about the same axis.
This ensures that the inertia of the rotor will not obscure the natural feel of the proper swing.
Unlike prior devices, the swing trainer of the present invention does not constrain the golfer's swing to a predetermined path.
Instead, the golfer is allowed to develop his own swing, with the swing trainer providing an immediate indication when the golfer's swing deviates from the proper path.
In preferred embodiments, the rotor is supported on a pedestal that includes a plurality of legs individually adjustable so that the rotor may be supported on sloping or uneven ground.
Additionally, preferred embodiments will generally allow for the convenient adjustment of the slope of the rotor's axis with respect to the ground to accommodate practice with a variety of different clubs.
Adjustment of the axis slope may be facilitated by a simple inclinometer mounted on the rotor support.
