Abstract

The exerciser includes a shaft. A weight is slidably mounted on the shaft. A golf club handle is formed at one end of the shaft and a stop is formed at the end of the shaft remote from the handle. A coil spring is mounted between the slidably mounted weight and the stop on the end of the shaft when the exerciser is swung. The slidably mounted weight is heavy enough so that when the exerciser is swung the person using it can feel the increased torque in the exercise caused by the movement of the weight down the shaft whereby the person using the exerciser can learn the feel of a correct golf swing.

Claims

1. A golf club swing trainer for training arm muscles to improve a golf swing comprising a truncated golf club shaft, a weight slidably mounted on the shaft, a golf club handle formed on one end of the shaft, resistance means on the shaft for regulating the speed of said weight toward the end of the shaft remote from the handle when the swing trainer is swung, the magnitude of the slidably mounted weight sufficiently large so when the swing trainer is swung like a golf club, the sensation of increased torque caused when centrifugal force causes the weight to move down the shaft, can be felt in the arms of the person using the device, whereby the person using the swing trainer learns the feel of a correct golf swing.

2. The trainer described in claim 1 including means for varying the speed of the weight down the shaft when the exerciser is swung.

3. The trainer described in claim 1 including means for preventing the exerciser from slipping out of the hands of the person swinging it, whereby the exerciser can be held with a light grip.

4. The trainer described in claim 1 including means for varying the magnitude of said weight slidably mounted on the shaft, whereby the speed of the weight down the shaft can be varied when the exerciser is swung.

5. A golf club swing trainer for training arm muscles to improve a golf swing comprising a truncated golf club shaft, a weight slidably mounted on the shaft, a golf club handle formed on one end of the shaft, a stop on the shaft to limit the movement of the weight towards the handle, a limit stop at the end of the shaft remote from the handle, a coil spring mounted on the shaft, the ends of the coil spring abutting the weight and the stop at the end of the shaft remote from the handle, the magnitude of the slidably mounted weight sufficiently large so when the swing trainer is swung like a golf club the sensation of increased torque caused when centrifugal force acting on the weight overcomes the resistance offered by the coil spring causing the weight to slide down the shaft, can be detected in the arms of the person using the device whereby the person using the device learns the feel of a correct swing.

6. The trainer described in claim 5 including means for varying the compression of said coil spring whereby the speed of the weight down the shaft can be varied when the exerciser is swung.

7. The trainer described in claim 6 wherein said means for varying the compression of the coil spring comprises means for changing the position of the limit stop on the shaft whereby the compression of the coil spring abutting the stop at the end of the shaft and the slidably mounted weight can be varied.

8. The trainer described in claim 5 including means for varying the magnitude of said weight slidably mounted on the shaft whereby the speed of the weight down the shaft can be varied when the exerciser is swung.

9. The trainer described in claim 5 including means for preventing the exerciser from slipping out of the hands of the person swinging it, whereby the exerciser can be held with a light grip.

10. The trainer described in claim 9 wherein said means for preventing the exerciser from slipping out of the hands of a person swinging it comprises a strap in the form of a loop attached to the handle of the exerciser, whereby when the hand of a person using the exerciser extends through said loop, the person swinging the exerciser can grasp it lightly.

11. A golf club swing trainer for training arm muscles to improve a golf swing comprising a truncated golf club shaft, a weight slidably mounted on the shaft, a golf club handle formed on one end of the shaft, a limit stop on the shaft to limit the movement of the weight towards the handle, a stop at the end of the shaft remote from the handle, a coil spring for regulating the speed of the weight toward the end of the shaft remote from the handle when the swing trainer is swung, mounted on the shaft, the ends of said coil spring abutting the stop on the end of the shaft and said weight, the resistance of the coil spring and the magnitude of the slidably mounted weight chosen so when the swing trainer is swung like a golf club the sensation of increased torque caused when the weight slides down the shaft can be felt in the arms of the person using the exerciser, whereby the person using the golf club swing trainer learns the feel of a correctly swung golf club.

12. The trainer described in claim 11 including means for varying the speed of the slidably mounted weight down the shaft when the exerciser is swung.

13. The trainer described in claim 11 including means for varying the magnitude of the slidably mounted weight on the shaft whereby the speed of said weight down the shaft can be varied when the exerciser is swung.

14. The trainer described in claim 11 including means for preventing the exerciser from slipping out of the hands of the person swinging it, whereby the exerciser can be held with a light grip.

15. The trainer described in claim 14 wherein said means for preventing the exerciser from slipping out of the hands of a person swinging it comprises a strap in the form of a loop attached to the handle of the exerciser, whereby when the hand of a person using the exerciser extends through said loop, the person swinging the exerciser can grasp it lightly.

16. The trainer described in claim 11 including means for varying the compression of said coil spring whereby the speed of the slidably mounted weight down the shaft can be varied when the exerciser is swung.

17. The trainer described in claim 16 wherein said means for varying the compression of the coil spring comprises means for changing the position of the limit stop on the shaft whereby the compression of the coil spring abutting the stop at the end of the shaft and the slidably mounted weight can be varied.

18. A golf club swing trainer for training arm muscles to improve a golf swing comprising a truncated golf club shaft, a weight slidably mounted on the shaft, a golf club handle formed on one end of the shaft, resistance means on the shaft for regulating the speed of said weight toward the end of the shaft remote from the handle when the swing trainer is swung, the magnitude of the slidably mounted weight sufficiently large so when the swing trainer is swung like a golf club, the sensation of increased torque caused when centrifugal force causes the weight to move down the shaft, can be felt in the arms of the person using the device, whereby the person using the swing trainer learns the feel of a correct golf swing, and means for varying the magnitude of said weight slidably mounted on the shaft, whereby the speed of the weight down the shaft can be varied when the trainer is swung, said means for varying the magnitude of the slidably mounted weight on the shaft comprising a sleeve formed from an elastic fabric covering the slidably mounted weight, the length of the sleeve larger than the length of said slidably mounted weight, and additional weights removably mounted in said sleeve embracing said shaft and held in said embrace by said sleeve for increasing the magnitude of the slidably mounted weight on said shaft.
