Abstract

A multipurpose exercise machine requiring only three points of adjustment centrally located. It has a one point height adjustment and two adjustments for the rotating arm assemblies. Dip and chin up bars are attached to the arm assemblies. The machine contains an integrated swingable workout bench. Through the use of a pulley system and counter balance assembly, the cable system maintains tension and provides a constant length of cable.

First claim

The invention claimed is:

1. A three-point adjustment multipurpose exercise machine, comprising:
a frame comprising a substantially upright post defining a substantially vertical axis;
a sliding carriage assembly slidably mounted on the upright post for movement along the substantially vertical axis;
a first locking device configured for releasably locking the sliding carriage assembly at a selected height on the upright post;
a first arm assembly comprising a first handle unit and a first arm rotatably mounted on the sliding carriage assembly for rotation about a first pivot axis;
a second locking device configured for releasably locking the first arm assembly at a selected rotated position about the first pivot axis;
a second arm assembly comprising a second handle unit and a second arm rotatably mounted on the sliding carriage assembly for rotation about a second pivot axis;
a third locking device configured for releasably locking the second arm assembly at a selected rotated position about the second pivot axis;
a source of exercise resistance;
a cable assembly coupling the first handle unit, the second handle unit, and the source of exercise resistance; and
means for keeping tension in the cable assembly substantially the same irrespective of the selected height for the sliding carriage assembly,
wherein the selected rotated positions for the first and second arm assemblies, about the respective first and second pivot axes, defines a horizontal span between the first and second handle units.

2. The exercise machine according to claim 1 , wherein the first and second pivot axes are substantially parallel.

3. The exercise machine according to claim 1 , wherein the first and second pivot axes are substantially horizontal.

4. The exercise machine according to claim 1 , further comprising:
a first chin-up and dip bar assembly associated with the first arm assembly; and
a second chin-up and dip bar assembly associated with the second arm assembly.

5. The exercise machine according to claim 1 , further comprising:
a bench rotatably mounted to the frame; and
a fourth locking device for releasably locking the bench in position for use in performing an exercise.

6. The exercise machine according to claim 1 , further comprising rollers associated with either the upright post or the sliding carriage assembly, the rollers configured to aid the movement of the sliding carriage assembly along the substantially vertical axis.

7. The exercise machine according to claim 1 , further comprising a counterbalance assembly associated with the sliding carriage assembly, the counterbalance assembly configured to aid the movement of the sliding carriage assembly along the substantially vertical axis.

8. The exercise machine according to claim 7 , wherein the counterbalance assembly comprises a counterweight.

9. The exercise machine according to claim 7 , wherein the counterbalance assembly comprises a gas spring cylinder.

10. The exercise machine according to claim 1 , wherein the first locking device comprises a spring-loaded pin configured to engage at least one corresponding aperture.

11. The exercise machine according to claim 1 , wherein the second and third locking devices each comprisse a spring-loaded pin configured to engage at least one corresponding aperture.

12. The exercise machine according to claim 1 , wherein the means for keeping tension in the cable assembly substantially the same irrespective of the selected height for the sliding carriage assembly, comprises a cable compensator assembly comprising:
a cable having a first end coupled to the sliding carriage assembly and a second end anchored to the frame; and
one or more pulleys associated with the cable.

13. A three-point adjustment multipurpose exercise machine, comprising:
a frame comprising a substantially upright post defining a substantially vertical axis;
a sliding carriage assembly slidably mounted on the upright post for movement along the substantially vertical axis;
a first locking device configured for releasably locking the sliding carriage assembly at a selected height on the upright post;
a first arm assembly comprising a first handle unit and a first arm rotatably mounted on the sliding carriage assembly for rotation about a first pivot axis;
a second locking device configured for releasably locking the first arm assembly at a selected rotated position about the first pivot axis;
a second arm assembly comprising a second handle unit and a second arm rotatably mounted on the sliding carriage assembly for rotation about a second pivot axis;
a third locking device configured for releasably locking the second arm assembly at a selected rotated position about the second pivot axis;
a source of exercise resistance; and
a cable assembly coupling the first handle unit, the second handle unit, and the source of exercise resistance; and
wherein the cable assembly is configured such that tension in the cable assembly remains substantially the same irrespective of the selected height for the sliding carriage assembly,
wherein the selected rotated positions for the first and second arm assemblies, about the respective first and second pivot axes, defines a horizontal span between the first and second handle units.

14. The exercise machine according to claim 13 , wherein the first and second pivot axes are substantially parallel.

15. The exercise machine according to claim 13 , wherein the first and second pivot axes are substantially horizontal.

16. The exercise machine according to claim 13 , further comprising:
a first chin-up and dip bar assembly associated with the first arm assembly; and
a second chin-up and dip bar assembly associated with the second arm assembly.

17. The exercise machine according to claim 13 , further comprising:
a bench rotatably mounted to the frame; and
a fourth locking device for releasably locking the bench in position for use in performing an exercise.

18. The exercise machine according to claim 13 , further comprising rollers associated with either the upright post or the sliding carriage assembly, the rollers configured to aid the movement of the sliding carriage assembly along the substantially vertical axis.

19. The exercise machine according to claim 13 , further comprising a counterbalance assembly associated with the sliding carriage assembly, the counterbalance assembly configured to aid the movement of the sliding carriage assembly along the substantially vertical axis.

20. The exercise machine according to claim 19 , wherein the counterbalance assembly comprises a counterweight.

21. The exercise machine according to claim 19 , wherein the counterbalance assembly comprises a gas spring cylinder.

22. The exercise machine according to claim 13 , wherein the first locking device comprises a spring-loaded pin configured to engage at least one corresponding aperture.

23. The exercise machine according to claim 13 , wherein the second and third locking devices each comprises a spring-loaded pin configured to engage at least one corresponding aperture.
