  • Golf swing trainer
    Patent number: 4889343
    Abstract: A golf club swing trainer has a handle portion and a shank portion connected together by a pivotable connecting assembly. One or more weights are connected to, and off-set from, the lower part of the shank portion. In use, if the user does not use proper arm, wrist and shoulder movement to form a proper swing plane, the off-set weights will cause a large torque to be generated around the axis of the club, causing the shank portion to rotate around the longitudinal axis of the handle portion.
