Abstract

Claims (66)

1. A strength training apparatus, comprising:

a base member;

a tower structure coupled to the base member;

at least one arm coupled to the tower structure;

a pulley being coupled to the at least one arm;

a cable extending through the pulley;

a handle coupled to a first end of the cable;

a flywheel connected to the tower structure;

a magnetic braking mechanism that resists movement of the flywheel; and

a console in communication with the magnetic braking mechanism;

wherein displacement of the handle results in rotation of the flywheel.

2. The strength training apparatus of claim 1 , further including a biasing member that returns the handle without causing rotation of the flywheel.

3. The strength training apparatus of claim 2 , wherein the biasing member is in communication with a sprocket, and the cable extends through the sprocket.

4. The strength training apparatus of claim 3 , wherein the sprocket is displaceable relative to the tower structure when the handle is pulled.

5. The strength training apparatus of claim 1 , wherein the at least one arm is pivotally coupled to the tower structure.

6. The strength training apparatus of claim 5 , wherein the at least one arm is movable with respect to the tower structure to position the handle at multiple locations with respect to the tower structure.

7. The strength training apparatus of claim 1 , further including a torque sensor proximate the flywheel.

8. The strength training apparatus of claim 7 , wherein the console is configured to provide an indication of an amount of work upon rotation of the flywheel.

9. The strength training apparatus of claim 7 , wherein the console further includes an input for selecting an amount of resistance applied by the magnetic braking mechanism to the flywheel.

10. The strength training apparatus of claim 1 , wherein the cable includes a second end that is fixed to the tower structure.

11. The strength training apparatus of claim 1 , wherein the cable is in communication with a drive mechanism, and the drive mechanism is attached to a shaft supporting the flywheel through a drive belt.

12. The strength training apparatus of claim 11 , wherein the drive mechanism includes an input shaft and an output shaft.

13. The strength training apparatus of claim 12 , wherein the input shaft is rotational in a first direction and a second direction opposite the first direction, and the output shaft is rotational in just the first direction.

14. A strength training apparatus, comprising:

a base member;

a tower structure couple to the base member;

at least one arm coupled to the tower structure;

a pulley being coupled to the at least one arm;

a cable extending through the pulley;

a handle coupled to a first end of the cable;

a flywheel connected to the tower structure;

a magnetic braking mechanism that resists movement of the flywheel;

a console in communication with the magnetic braking mechanism; and

a drive mechanism in communication with the cable, the drive mechanism further including:

an input shaft;

a concentric output shaft disposed within the input shaft;

wherein the drive mechanism is in communication with the flywheel through a drive belt;

wherein the input shaft is rotational in a first direction and a second direction opposite the first direction, and the concentric output shaft is rotational in just the first direction;

wherein displacement of the handle results in rotation of the flywheel.

15. The strength training apparatus of claim 14 , wherein the cable includes a second end that is fixed to the tower structure.

16. The strength training apparatus of claim 14 , further a biasing member that returns the handle without causing rotation of the flywheel.

17. The strength training apparatus of claim 16 , wherein the biasing member is in communication with a sprocket that supports a portion of the cable.

18. The strength training apparatus of claim 17 , wherein the sprocket is displaceable relative to the tower structure when the handle is pulled.

19. The strength training apparatus of claim 14 , further including:

a torque sensor proximate the flywheel;

wherein the console is configured to provide an indication of an amount of work performed upon rotation of the flywheel.

20. A strength training apparatus, comprising:

a base member;

a tower structure couple to the base member;

at least one arm coupled to the tower structure;

a pulley being coupled to the at least one arm;

a cable extending through the pulley;

the cable includes a second end that is fixed to the tower structure;

a handle coupled to a first end of the cable;

a flywheel connected to the tower structure;

a magnetic braking mechanism that resists movement of the flywheel;

a console in communication with the magnetic braking mechanism;

a drive mechanism in communication with the cable, the drive mechanism further including:

an input shaft;

a output shaft disposed within the input shaft;

a biasing member that returns the handle without causing rotation of the flywheel;

a sprocket that supports a portion of the cable is in communication with the biasing member; and

the sprocket is displaceable relative to the tower structure when the handle is pulled;

wherein the drive mechanism is in communication with the flywheel through a drive belt;

wherein the input shaft is rotational in a first direction and a second direction opposite the first direction, and the output shaft is rotational in just the first direction;

wherein displacement of the handle results in rotation of the flywheel.
