Abstract

A golf swing training device including a chamber having a liquid-receiving interior and a shaft connected to an end of the chamber. The shaft includes a gripping area opposite the chamber. A liquid partially fills an interior of the chamber. The chamber includes a tubular body, a first cap affixed in liquid-tight relationship to one end of the tubular body, and a second cap affixed in liquid-tight relationship to an opposite end of the tubular body. The shaft has the shape of a conventional golf club shaft. The movement of liquid within the chamber provides the golfer with immediate feedback as to the correctness of the swing.

Claims

1. A golf swing training device comprising:

a chamber having a liquid-receiving interior, said chamber having a lower end without a golf club head connected thereto;

a liquid partially filling said interior of said chamber; and

a shaft connected to an end of said chamber opposite said lower end, said shaft having a gripping area opposite said chamber, said shaft having a longitudinal axis aligned with a longitudinal axis of said chamber.

2. The device of claim 1, said chamber having a threaded opening opposite said lower end, said opening threadedly receiving an end of said shaft therein.

3. The device of claim 1, said chamber comprising:

a tubular body;

a first cap affixed in liquid-tight relationship to one end of said tubular body; and

a second cap affixed in liquid-tight relationship to an opposite end of said tubular body.

4. The device of claim 3, said tubular body having said liquid contained therein between said first and second caps.

5. The device of claim 4, said liquid filling less than three-quarters of said tubular body.

6. The device of claim 3, said second cap having a threaded opening therein, said threaded opening for receiving an end of said shaft.

7. The device of claim 1, said shaft having a shape of a golf club shaft, said shaft terminating at said chamber.

8. The device of claim 1, said shaft being solid aluminum shaft, said shaft affixed to said chamber so as to seal said end of said chamber opposite said lower end.

9. A golf swing training device comprising:

a single chamber partially filled with a liquid, said liquid being freely flowable between ends of said chamber; and

a shaft connected to one end of said chamber so as to completely seal an interior of said chamber, said shaft having a configuration of a conventional golf club shaft, said shaft having a longitudinal axis aligned with a longitudinal axis of said chamber.

10. The device of claim 9, said chamber having a lower end opposite said end connected to said shaft, said lower end being without a golf club head attached thereto.

11. The device of claim 10, said chamber having a threaded opening opposite said lower end, said opening threadedly receiving an end of said shaft therein.

12. The device of claim 9, said chamber comprising:

a tubular body;

a first cap affixed in liquid-tight relationship to one end of said tubular body; and

a second cap affixed in liquid-tight relationship to an opposite end of said tubular body.

13. The device of claim 12, said tubular body having said liquid contained therein between said first and second caps, said liquid filling less than three-quarters of said tubular body.
