  • Patent number: 4969921
    Abstract: A golf club swing training device is mounted to the shaft of a golf club to enable a user to improve muscle coordination and follow through during swinging of the golf club. The training device is in the form of a tube which is clamped in a parallel spaced apart relationship to the shaft. A weight is disposed within the tube in axially slidable engagement. A spring biases the weight towards the first or upper end of the tube when attached to the golf club. Upon the user swinging the golf club, centrifugal force urges the weight toward the second or lower end of the tube so that the user feels increased torque during the swing. The weight may further be fixed in a selected position within the tube by a retainer pin received through the tube and engaging the weight therein to provide a fixed weight during the swing.
