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 reversible resistance system, comprising:
a frame having a first end and a second end, wherein the frame is comprised of a first rail and a second rail;
a first handle and a second handle connected to the frame near the first end of the frame;
an elongated member movably positioned upon said frame, wherein said elongated member has a first run and a second run between said first end and said second end of said frame, wherein when said first run moves in a first direction said second run moves in a second direction that is substantially opposite of said first direction, and wherein when said first run moves in said second direction said second run moves in said first direction;
an exercise implement movably connected to said frame, wherein the exercise implement is comprised of a carriage slidably positioned upon 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;
a resistance device connected to said elongated member, wherein said resistance device applies a resistance force to said elongated member and said exercise implement in said second direction relative to said first run and wherein said resistance device applies said resistance force to said elongated member and said exercise implement in said first direction relative to said second run; and
a clutch connected to said exercise implement, wherein said clutch includes an engagement portion having a first end and a second end, wherein said first end is adapted to selectively engage said first run and said second end is opposite of said first end and adapted to selectively engage said second run of said elongated member, such that said exercise implement is configured to provide said resistance force to an exerciser in said second direction when said clutch is engaged to said first run, and said exercise implement is configured to provide said resistance force to said exerciser in said first direction when said clutch is engaged to said second run.

2. The exercise machine reversible resistance system of claim 1 , wherein said first run and said second run are substantially parallel with respect to one another.

3. The exercise machine reversible resistance system of claim 2 , wherein said first run is positioned above said second run.

4. The exercise machine reversible resistance system of claim 2 , wherein said first run is positioned to a side of said second run.

5. The exercise machine reversible resistance system of claim 1 , wherein said first run and said second run are horizontally aligned.

6. The exercise machine reversible resistance system of claim 1 , wherein said first run and said second run are vertically aligned.

7. The exercise machine reversible resistance system of claim 1 , wherein said clutch is comprised of a linear clutch.

8. The exercise machine reversible resistance system of claim 1 , wherein said elongated member is comprised of an endless loop structure.

9. The exercise machine reversible resistance system of claim 8 , including a first wheel rotatably connected to said frame and a second wheel rotatably connected to said frame, wherein said elongated member is movably positioned upon said first wheel and said second wheel, wherein said first run and said second run are positioned between said first wheel and said second wheel.

10. The exercise machine reversible resistance system of claim 9 , wherein said elongated member includes a plurality of teeth selectively engageable by said clutch.

11. The exercise machine reversible resistance system of claim 10 , wherein said plurality of teeth extend inwardly.

12. The exercise machine reversible resistance system of claim 11 , wherein said elongated member is comprised of a belt.

13. The exercise machine reversible resistance system of claim 9 , wherein said resistance device is connected to said first wheel to apply said resistance force against rotation of said first wheel in a first rotational direction.

14. The exercise machine reversible resistance system of claim 1 , wherein said resistance device is comprised of a bias member, wherein said bias member is elongated and resilient.

15. The exercise machine reversible resistance system of claim 13 , wherein said bias member is comprised of a spring.

16. The exercise machine reversible resistance system of claim 1 , wherein said elongated member is comprised of a chain.

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

18. An exercise machine reversible resistance system, comprising:
a frame having a first end and a second end, wherein the frame is comprised of a first rail and a second rail;
a first handle and a second handle connected to the frame near the first end of the frame; an elongated member movably positioned upon said frame, wherein said elongated member is comprised of an endless loop structure, wherein said elongated member has a first run and a second run between said first end and said second end of said frame, wherein when said first run moves in a first direction said second run moves in a second direction that is substantially opposite of said first direction, and wherein when said first run moves in said second direction said second run moves in said first direction;
wherein said first run and said second run are substantially parallel with respect to one another;
an exercise implement movably connected to said frame, wherein the exercise implement is comprised of a carriage slidably positioned upon 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;
a resistance device connected to said elongated member, wherein said resistance device applies a resistance force to said elongated member and said exercise implement in said second direction relative to said first run and wherein said resistance device applies said resistance force to said elongated member and said exercise implement in said first direction relative to said second run;
a clutch connected to said exercise implement, wherein said clutch includes an engagement portion having a first end and a second end, wherein said first end is adapted to selectively engage said first run and said second end is opposite of said first end and adapted to selectively engage said second run of said elongated member, such that said exercise implement is configured to provide said resistance force to an exerciser in said second direction when said clutch is engaged to said first run, and said exercise implement is configured to provide said resistance force to said exerciser in said first direction when said clutch is engaged to said second run, wherein said clutch is comprised of a linear clutch;
and a first wheel rotatably connected to said frame and a second wheel rotatably connected to said frame, wherein said elongated member is movably positioned upon said first wheel and said second wheel, wherein said first run and said second run are positioned between said first wheel and said second wheel.
