Abstract

A device for improving the mechanics of a golfer'"'"'s swing which is attached to the golf club and adjacent to the grip, and which emits a continuous audible signal so long as the device is subjected to at least a predetermined centrifugal force which is generated by swinging the club. The device includes a battery, buzzer and switch which is spring biased to force the switch open. The spring is compressed by the centrifugal force generated by swinging the club to allow the switch to close and activate the buzzer. The spring may be adjustably prestressed to vary the amount of centrifugal force needed to close the switch.

Claims

1. A golf club swing training device comprising the combination of a golf club and an attachment therefor, said attachment comprising, housing means attachable to said shaft, electrically operated means within said housing actuated by centrifugal force generated by swinging the club, said electrically operated means having audbile signal emitting means for emitting a continuous audible signal for as long as the club speed achieved during the swing generates a centrifugal force equal to or greater than a predetermined minimum, the housing attachment means being positionable on the club shaft approximately at the swing weight point on the club as determined by a swing weight machine such that there is no substantial change in the swing weight of the club with the device attached.

2. The combination of claim 1 in which the audible signal emitting means further comprises means for varying the amount of centrifugal force needed to cause the audible signal emitting means to emit the audible signal.

3. The combination of claim 1 in which the audible signal emitting means comprises a circuit having a power source, buzzer and switch, and resilient means biased to force the switch open and responsive to the centrifugal force generated by swinging the club so that when the centrifugal force is equal to or greater than the predetermined minimum, the switch will close against the force of the resilient means to close the circuit and activate the buzzer for as long as the centrifugal force exceeds the predetermined minimum.
