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

What is claimed is:

1. An exercise machine, comprising:
a frame;
a first end platform connected to the frame;
an exercise implement movably connected to 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 in the second direction relative to the first run, and wherein the resistance device applies the resistance force to the elongated member in the first direction relative to the second run;
a clutch connected to the exercise implement, wherein the clutch includes an engagement portion, wherein the engagement portion is adapted to selectively engage the first run and the second run of the elongated member, such that the resistance device is configured to provide the resistance force to the exercise implement in the second direction when the clutch is engaged to the first run, and the resistance device is configured to provide the resistance force to the exercise implement in the first direction when the clutch is engaged to the second run; and
wherein the resistance device is comprised of a spring or an elastic member.

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 resistance device is connected to the first wheel to apply the resistance force against rotation of the first wheel in a first rotational direction.

5. The exercise machine of claim 1 , wherein the elongated member includes a plurality of teeth selectively engageable by the clutch.

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

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

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

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

10. The exercise machine of claim 1 , wherein the elongated member is comprised of a belt.

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

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

13. 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 engagement portion includes a first end and a second end opposite of the first end, wherein the first end of the engagement portion is adapted to selectively engage the first run in the retracted position, and the second end of the engagement portion is adapted to selectively engage the second run in the extended position.

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

15. The exercise machine of claim 1 , wherein the exercise implement is comprised of a carriage.

16. The exercise machine of claim 1 , wherein the exercise implement is comprised of a handle.

17. An exercise machine, comprising:
a frame;
a first end platform connected to the frame;
an exercise implement movably connected to 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 exercise implement in the second direction relative to the first run, and wherein the resistance device applies the resistance force to the elongated member and the exercise implement in the first direction relative to the second run;
a clutch connected to the exercise implement, wherein the clutch includes an engagement portion, wherein the engagement portion is adapted to selectively engage the first run and the second run of the elongated member, such that the resistance device is configured to provide the resistance force to the exercise implement in the second direction when the clutch is engaged to the first run, and the resistance device is configured to provide the resistance force to the exercise implement in the first direction when the clutch is engaged to the second run;
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 engagement portion includes a first end and a second end opposite of the first end, wherein the first end of the engagement portion is adapted to selectively engage the first run in the retracted position, and the second end of the engagement portion is adapted to selectively engage the second run in the extended position; and
wherein the resistance device is comprised of a spring or an elastic member.

18. An exercise machine, comprising:
a frame;
an exercise implement movably connected to the frame;
wherein the frame includes a first rail and a second rail, wherein the second rail is parallel with respect to the first rail, and wherein the exercise implement is movably positioned upon the first rail and the second rail;
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 in the second direction relative to the first run, and wherein the resistance device applies the resistance force to the elongated member in the first direction relative to the second run;
a clutch connected to the exercise implement, wherein the clutch includes an engagement portion, wherein the engagement portion is adapted to selectively engage the first run and the second run of the elongated member, such that the resistance device is configured to provide the resistance force to the exercise implement in the second direction when the clutch is engaged to the first run, and the resistance device is configured to provide the resistance force to the exercise implement in
