Abstract
A golf swing training device comprising an elongate golf club shaft provided with a golf club hand grip at the upper end thereof and a weighted mechanical head assembly fixedly connected to the lower end thereof. The shaft is connected to the mechanical head assembly by an improved connector assembly. The mechanical head assembly comprises a spring biased weighted cartridge member positioned within a barrel housing and provided with snap ring-engaging fingers extending outwardly through slots provided in the barrel housing. The barrel housing is provided with an adjustable head closure member at the lower end thereof which is adapted to selectively increase or decrease tension of the cartridge-engaging main spring contained in the barrel housing. A cartridge-engaging main spring is positioned within the barrel housing by use of upper and lower locator bearings. A snap ring is provided for selective slidable movement along the external surface of the barrel housing and is retained at the upper portion thereof by the cartridge snap ring-engaging fingers which extend through the slots of the barrel housing when the golf swing training device is not in use. Upon execution of a properly executed golf swing, the resultant centrifugal force causes the spring loaded weighted cartridge to move downwardly within the barrel so as to cause the snap ring-engaging fingers to retract within the barrel, thereby releasing the snap ring which proceeds downwardly along the outer surface of the barrel at a high rate of speed until it collides with the edge of the adjustable head housing so as to produce a loud snap and a resultant physical feeling as if a golf club had properly struck a golf ball.
