Abstract

A tug of war machine is described which includes a belt loop which is pulled in a generally horizontal direction. The resistance placed on the loop can be selected to either provide a static pull or a hand-over-hand tug of war-type pulling exercise. Additionally, a treadmill may be used in conjunction with the tug of war loop cord to provide simultaneous exercise for the legs and the back. A monitor displays the performance of the user and compares this performance with the effort relative to a predetermined standard of reference.

Claims

1. A tug of war exercise machine to exercise an individual in a generally upright position comprising:

stationary support means generally at a height within the range of the reach of an individual'"'"'s hand while in standing exercise stance;

force responsive means on said support means to measure force exerted on said support means;

elongated pulling means in the form of a closed loop coupled to said force responsive means and available to be engaged by the individual and pulled in a generally horizontal direction away from said support and force responsive means;

resistance means operationally connected to said elongated pulling means to provide an adjustable resistance to said elongated pulling means; and

indicating means cooperating with said force responsive means for providing an indication as to the effort of the individual relative to a predetermined standard or reference.

2. A tug of war exercise machine as defined in claim 1, wherein said stationary means comprises an upright console.

3. A tug of war exercise machine as defined in claim 2, wherein said indicating means includes a video monitor is housed within said console and faces the individual when pulling on said elongate pulling means.

4. A tug of war exercise machine as defined in claim 1, wherein said indicating means comprises means comprises means for producing an audio output.

5. A tug of war exercise machine as defined in claim 4, wherein said audio output has a pitch which varies with the deviation between the individual'"'"'s effort and said predetermined standard or reference.

6. A tug of war exercise machine as defined in claim 4, wherein said indicating means includes means for producing synthesized audio speech output.

7. A tug of war exercise machine as defined in claim 1, wherein said force responsive means comprises means for fixing said elongate pulling means to allow the individual to isometrically pull on said elongate pulling means without movement of said elongate pulling means, said indicating means indicating the horizontal pulling force applied by the individual.

8. A tug of war exercise machine as defined in claim 1, wherein said elongate pulling means comprises a cord or cable mounted for movement relative to said support means, and tension control means for applying a tension to said cord or cable as a function of the pulling forces applied by the individual, whereby the individual can pull, said cord or cable in a hand-over-hand movement to stimulate a tug of war contest.

9. A tug of war exercise machine as defined in claim 8, wherein said tension control means comprises means to provide an isotonic force relationship which maintains a substantially equal tension on said cord or cable independently of the velocity or speed with which said cord or cable is pulled.

10. A tug of war exercise machine as defined in claim 8, wherein said tension control means comprises means to provide an isokinetic force relationship which maintains a substantially constant velocity of said cord or cable independently of the force applied to said cord or cable.

11. A tug of war exercise machine as defined in claim 1, further comprising a treadmill having a belt upon which the individual stands when pulling said elongated pulling means;

and means for enabling the portion of said treadmill belt upon which the individual stands to move in the direction of said stationary support means, whereby the individual experiences a backward walking motion while pulling said elongated pulling means.

12. A tug of war exercise machine as defined in claim 11, further comprising for coupling of said treadmill to said indicating means, whereby said indicating means illustrates the efforts of the individual as a function of the velocity of movement of said treadmill.

13. A tug of war exercise machine as defined in claim 1, wherein said indicating means comprises input means for receiving information in predetermined categories for purposes of establishing said predetermined standard for reference.

14. A tug of war exercise machine as defined in claim 1, further comprising timer means for timing the duration of the exercise.

15. A tug of war machine as defined in claim 1, further comprising a treadmill coupled to said elongated pulling means;

clutch means coupled to said elongate pulling means and to said treadmill for selectively engaging and disengaging said elongated pulling means from said treadmill, whereby said elongated pulling means and said treadmill can operate both independently and simultaneously.

16. A tug of war exercise machine as defined in claim 1, further comprising a video monitor;

and microprocessor means coupled to said video monitor and said force responsive means for showing opponents isometrically pulling on said elongated pulling means and being pulled into a pit as the force applied by the individual increases.

17. A tug of war machine as defined in claim 1, further comprising a video monitor;

microprocessor means coupled to said video monitor and said force responsive means for showing opponents isokinetically pulling on said elongated pulling means and being pulled into a pit as the effort applied by the individual increases.

18. A tug of war machine as defined in claim 1, further comprising a video monitor;

microprocessor means coupled to said video monitor and said force responsive means for showing opponents isotonically pulling on said elongated pulling means and being pulled into a pit as the effort applied by the individual increases.

19. A tug of war machine as defined in claim 1, further comprising a video monitor;

microprocessor means coupled to said video monitor and said force responsive means for showing opponents accommodating resistively pulling on said elongate pulling means and being pulled into a pit as the effort applied by the individual increases.

20. A tug of war exercise machine as defined in claim 1, wherein said force responsive means includes braking means for braking said elongated pulling means.
