Abstract

A golf swing training apparatus is used to produce a data signal representative of the golfer'"'"'s swing tempo. The apparatus includes a golf swing guide having a number of individual induction type sensors located at spaced locations therein. Each sensor sequentially provides a computer microprocessor with sensor readings as the golf club or club shaft passes thereby. The processor thereafter converts the sensor readings into an output representative of the golf swing tempo. To analyze a particular golfer'"'"'s swing, the golfer stands in the training apparatus and swings his golf club. On each of the swing backstroke, downstroke and follow-through the club slides along the swing guide sequentially activating each of the sensors. The microprocessor instantaneously converts the timing between sequential sensor readings received into a graphically displayed output providing the golfer with substantially immediate feedback of the tempo of his golf swing.

Claims

1. A golf swing training apparatus comprising

a frame, a golf club swing guide for guiding a person'"'"'s golf swing, attached to said frame, the improvement wherein, said golf club swing guide including sensing means, said sensing means for generating a first set of data signals upon sensing movement of a golf club thereby during said person'"'"'s swing, said first set of data signals representative of a characteristic of said person'"'"'s golf club swing, and computing means having processing means for processing said first set of data signals for generating an output signal representative of said characteristics of said person'"'"'s swing.

2. A golf swing training apparatus as claimed in claim 1 wherein the sensor means comprises a plurality of sensors disposed at spaced locations along the swing guide for sensing the speed of the golf club along the swing guide.

3. A golf swing training apparatus as claimed in claim 2 wherein the computing means further includes memory storage means for storing a second set of data signals,

said second set of data signals being representative of a characteristic of at least one first prerecorded golf club swing,

the processing means for processing the second set of data signals for generating an output signal representative of said characteristic of said at least one prerecorded swing.

4. A golf swing training apparatus as claimed in claim 3 wherein,

each of said first and second sets of data signals is representative of the tempo of said person'"'"'s golf club swing and first prerecorded golf club swing respectively, and

said first prerecorded golf club swing is selected from a preferred golf club swing and a prior one of said person'"'"'s golf club swings.

5. A golf swing training apparatus as claimed in claim 4 wherein said storage means further stores a third set of data signals,

said third set of data signals being representative of the tempo of a second prerecorded golf club swing selected from the other of said preferred golf club swing and said prior one of said person'"'"'s golf club swings,

said processing means for processing said third set of data signals for generating said output signal,

said output signal representative of a comparison of said person'"'"'s golf club swing and one of said first and second prerecorded golf club swings.

6. A golf swing training apparatus as claimed in claim 3 wherein said computing means includes display means for displaying said output signal.

7. A golf swing training apparatus as claimed in claim 3 wherein said processing means processes sets of data signals from a plurality of golf swing training apparatus.

8. A golf swing training apparatus as claimed in claim 1 wherein said training apparatus further comprises a guide adjustment mechanism for adjusting the height and angle of said golf club swing guide.

9. A golf swing training apparatus as claimed in claim 8 wherein said guide adjustment mechanism comprises an electric motor.

10. A golf swing training apparatus as claimed in claim 8 wherein said storage means further stores data signals representative of pre-selected height and angle positions of said golf club swing guide for a plurality of users,

said computing means actuating said guide adjustment mechanism to move said golf club swing guide to a selected one of said pre-selected height and angle positions.

11. A golf swing training apparatus as claimed in claim 8 wherein said golf club swing guide forms a partial circle.

12. A golf swing training apparatus as claimed in claim 1 wherein said frame includes a base for sitting on the ground and a pair of vertical members for adjusting the height of said golf club swing guide.

13. A golf swing training apparatus as claimed in claim 1 wherein said sensing means comprises a plurality of individual spaced apart sensors.

14. A golf swing training apparatus as claimed in claim 13 wherein said golf swing guide includes an arcuate polymer pipe segment, and said sensors being located within said pipe segment.

15. A golf swing training apparatus as claimed in claim 13 wherein said sensors are induction sensors.

16. A golf swing training apparatus as claimed in claim 15 wherein said golf swing guide is an arcuate polyvinyl chloride pipe.

17. A golf swing training apparatus as claimed in claim 16 wherein said computing means comprises a personal computer.

18. A method of analyzing a golf swing using a golf swing training apparatus comprising

a frame,

a golf club swing guide for guiding a person'"'"'s golf swing, attached to said frame;

said golf club swing guide including a plurality of sensors for generating a first set of data signals upon sensing movement of a golf club thereby during said person'"'"'s swing, said first set of data signals representative of the tempo of said person'"'"'s swing, and

a microprocessor including storage for storing a second set of data signals, said second set of data signals being representative of the tempo of a prerecorded golf club swing,

said microprocessor having processing means for processing said sets of data signals for generating output signals,

said method comprising the steps of

swinging said golf club along said golf club swing guide to generate said first set of data signals, and

comparing an output signal generated from said first set of data signals with an output signal generated from said second set of data signals.

19. A method of analyzing a golf club swing as claimed in claim 18 wherein said prerecorded golf club swing is a preferred golf club swing.

20. A method of analyzing a golf club swing as claimed in claim 18 wherein said prerecorded golf club swing is a computer generated average of a plurality of said person'"'"'s previous golf club swings.
