Abstract: A hinged golf training club having a hinge that pivots rightwardly at a ninety degree angle relative to the reference plane 42 of zero degree clubhead 32. This device corrects the two main faults shared by all prior patents in this genre. The first fault is that their hinges are constructed so that the fork and the tongue members have flat surfaces contacting each other. The second fault is that some hinge both forwardly and rearwardly. This training club provides a construction that has a rounded male member contacting a rounded longitudinal cavity. The club looks substantially like and acts substantially like a conventional golf club in every way except for hinge 28, and allows the user to safely hit golf balls both on the range and on the course.

Abstract: A golf club shaft is provided with a pressure actuated switch on the handle and is operatively connected by an electrical circuit to a training head that has electromagnets mounted in both its forward and backward faces. When the golfer presses down on the switch, the energized electrical circuit causes a magnetically influenced ball or balls to attach to either or both of the forward or backward faces of the electromagnets; and when the pressure is let up, the ball instantly detachs from the face and will travel along the line that the device was swung through. Practice with the device provides the user with observable feedback as to the squareness of the face at release and the feel for the proper amount of acceleration needed to propel the ball a specified distance. When a golfer swings the device and releases the switch correctly, the simulated golf ball will have the proper end over end roll and travel straight towards its target at the right speed.
