Abstract

An exercise machine reversible resistance system for reversing the directional force of resistance against an exercise implement before, during, or after the performance of a routine of one or more exercises. The exercise machine reversible resistance system generally includes a frame, an elongated member movably positioned upon the frame, wherein the elongated member has a first run and a second run, a resistance device that applies a resistance force to the elongated member in a single direction, an exercise implement movably connected to the frame and a clutch connected to the exercise implement. The clutch is adapted to selectively engage the first run or the second run of the elongated member for selective control of the resistance direction of the exercise implement.

First claim

The invention claimed is:

1. An exercise machine, comprising:
a frame having a first end, a second end, and a first rail;
a carriage adapted to support an exerciser slidably positioned upon the first rail of the frame, wherein the carriage is slidable along a longitudinal axis of the frame between the first end and the second end of the frame;
an elongated member movably positioned upon the frame, wherein the elongated member has a first run and a second run, wherein when the first run moves in a first direction the second run moves in a second direction that is substantially opposite of the first direction, and wherein when the first run moves in the second direction the second run moves in the first direction;
a resistance device connected to the elongated member, wherein the resistance device applies a resistance force to the elongated member and the carriage in the second direction relative to the first run and wherein the resistance device applies the resistance force to the elongated member and the carriage in the first direction relative to the second run; and
a clutch connected to the carriage, wherein the clutch includes an engagement portion having a first end and a second end, wherein the first end is adapted to selectively engage the first run and the second end is opposite of the first end and adapted to selectively engage the second run of the elongated member, such that the carriage is configured to provide the resistance force to the exerciser in the second direction when the clutch is engaged to the first run, and the carriage is configured to provide the resistance force to the exerciser in the first direction when the clutch is engaged to the second run.

2. The exercise machine of claim 1 , wherein the elongated member is comprised of an endless loop structure.

3. The exercise machine of claim 2 , including a first wheel rotatably connected to the frame and a second wheel rotatably connected to the frame, wherein the elongated member is movably positioned upon the first wheel and the second wheel, wherein the first run and the second run are positioned between the first wheel and the second wheel.

4. The exercise machine of claim 3 , wherein the elongated member includes a plurality of teeth selectively engageable by the clutch.

5. The exercise machine of claim 4 , wherein the plurality of teeth extend inwardly.

6. The exercise machine of claim 5 , wherein the elongated member is comprised of a belt.

7. The exercise machine of claim 6 , wherein the resistance device is connected to the first wheel to apply the resistance force against rotation of the first wheel in a first rotational direction.

8. The exercise machine of claim 1 , wherein the resistance device is comprised of a bias member.

9. The exercise machine of claim 8 , wherein the bias member is elongated and resilient.

10. The exercise machine of claim 9 , wherein the bias member is comprised of a spring.

11. The exercise machine of claim 1 , wherein the first run and the second run are substantially parallel with respect to one another.

12. The exercise machine of claim 11 , wherein the first run is positioned above the second run.

13. The exercise machine of claim 11 , wherein the first run is positioned to a side of the second run.

14. The exercise machine of claim 1 , wherein the first run and the second run are horizontally aligned.

15. The exercise machine of claim 1 , wherein the first run and the second run are vertically aligned.

16. The exercise machine of claim 1 , wherein the clutch is comprised of a linear clutch.

17. The exercise machine of claim 1 , wherein the elongated member is comprised of a chain.

18. The exercise machine of claim 1 , wherein the clutch includes an actuator connected to the engagement portion and adapted to linearly translate the engagement portion to a retracted position and an extended position, wherein the first end of the engagement portion engages the first run in the retracted position, and the second end of the engagement portion engages the second run in the extended position.

19. The exercise machine of claim 1 , including:
a first end platform connected to the frame, wherein the first end platform is near the first end of the frame; and
a second end platform connected to the frame, wherein the second end platform is near the second end of the frame.

20. The exercise machine of claim 1 , wherein the frame includes a second rail, wherein the second rail is parallel with respect to the first rail, and wherein the carriage is movably positioned upon the first rail and the second rail.

21. An exercise machine, comprising:
a frame having a first end, a second end, and a first rail;
a first end platform connected to the frame, wherein the first end platform is near the first end of the frame;
a carriage adapted to support an exerciser slidably positioned upon the first rail of the frame, wherein the carriage is slidable along a longitudinal axis of the frame between the first end and the second end of the frame;
an elongated member movably positioned upon the frame, wherein the elongated member is comprised of an endless loop structure, wherein the elongated member has a first run and a second run, wherein when the first run moves in a first direction the second run moves in a second direction that is substantially opposite of the first direction, wherein when the first run moves in the second direction the second run moves in the first direction, wherein the first run and the second run are substantially parallel with respect to one another, and wherein the first run and the second run are horizontally aligned;
a resistance device connected to the elongated member, wherein the resistance device applies a resistance force to the elongated member and the carriage in the second direction relative to the first run and wherein the resistance device applies the resistance force to the elongated member and the carriage in the first direction relative to the second run; and
a clutch connected to the carriage, wherein the clutch includes an engagement portion having a first end and a second end, wherein the first end is adapted to selectively engage the first run and the second end is opposite of the first end and adapted to selectively engage the second run of the elongated member, such that the carriage is configured to provide the resistance force to the exerciser in the second direction when the clutch is engaged to the first run, and the carriage is configured to provide the resistance force to the exerciser in the first direction when the clutch is engaged to the second run.

22. The exercise machine of claim 21 , wherein the frame includes a second rail, wherein the second rail is parallel with respect to the first rail, and wherein the carriage is movably positioned upon the first rail and the second rail.

23. The exercise machine of claim 22 , including a second end platform connected to the frame, wherein the second end platform is near the second end of the frame.

24. An exercise machine, comprising:
a frame having a first end, a second end, and a first rail;
