Abstract

A control mechanism includes a friction brake assembly. The friction brake assembly includes a push rod and a friction pad connected to the push rod. The control mechanism also includes a magnetic resistance assembly. The magnetic resistance assembly includes a rotatable sleeve, a movable housing in contact with the rotatable sleeve, and at least one magnet disposed within the movable housing. The control mechanism also includes a knob in mechanical communication with both the push rod and the rotatable sleeve.

Claims

1. A control mechanism, comprising:

a friction brake assembly, the friction brake assembly comprising;

a push rod; and

a friction pad connected to the push rod;

a magnetic resistance assembly, the magnetic resistance assembly comprising;

a rotatable sleeve;

a movable housing in contact with the rotatable sleeve; and

at least one magnet disposed within the movable housing; and

a knob in mechanical communication with both the push rod and the rotatable sleeve.

2. The control mechanism of claim 1, further comprising a return mechanism in communication with the push rod.

3. The control mechanism of claim 1, wherein the push rod is mechanically isolated from the knob.

4. The control mechanism of claim 1, wherein the rotatable sleeve comprises at least one spline that interlocks with an inside surface of the knob and allows for axial movement of the knob with respect to the rotatable sleeve.

5. The control mechanism of claim 1, wherein the rotatable sleeve is rotationally interlocked with the knob so that the rotatable sleeve rotates when the knob rotates.

6. The control mechanism of claim 5, wherein the rotatable sleeve causes the movable housing to be pushed towards a flywheel when the knob is rotated in a first direction.

7. The control mechanism of claim 6, further comprising a threaded mover threadingly connected to an end of the rotatable sleeve where the threaded mover is in contact with the movable housing.

8. The control mechanism of claim 1, wherein the rotatable sleeve comprises a sleeve threaded portion.

9. The control mechanism of claim 8, further comprising a worm gear wherein the sleeve threaded portion is intermeshed with the worm gear.

10. The control mechanism of claim 9, further comprising a movement sensor wherein the movement sensor is attached to the worm gear.

11. The control mechanism of claim 1, wherein the movable housing pivots when the knob is rotated.

12. An exercise device, comprising:

a crank assembly, the crank assembly comprising;

a pedal; and

a pedal arm connected to the pedal;

a flywheel connected to the pedal arm;

a friction brake assembly, the friction brake assembly comprising;

a push rod; and

a friction pad connected to the push rod;

the friction pad being proximate to the flywheel so that upon activation of the push rod, the friction pad engages the flywheel;

a magnetic resistance assembly, the magnetic resistance assembly comprising;

a rotatable sleeve;

a movable housing in mechanical communication with the rotatable sleeve; and

at least one magnet disposed within the movable housing;

the movable housing being proximate the flywheel; and

a knob in mechanical communication with both the push rod and the rotatable sleeve.

13. The exercise device of claim 12, further comprising a return spring in communication with the push rod.

14. The exercise device of claim 12, wherein the push rod is mechanically isolated from the knob.

15. The exercise device of claim 12, wherein the rotatable sleeve comprises at least one spline that interlocks with an inside surface of the knob and allows for axial movement of the knob with respect to the rotatable sleeve.

16. The exercise device of claim 12, wherein the rotatable sleeve is rotationally interlocked with the knob so that the rotatable sleeve rotates when the knob rotates.

17. The exercise device of claim 16, wherein the rotatable sleeve causes the movable housing to move in axial direction when the knob is rotated in a first direction.

18. The exercise device of claim 12, wherein the rotatable sleeve comprises a sleeve threaded portion.

19. The exercise device of claim 18, further comprising a threaded mover intermeshed with a sleeve threaded portion, wherein the threaded mover is in contact with the movable housing.

20. A exercise device, comprising:

a crank assembly, the crank assembly comprising;

a pedal; and

a pedal arm connected to the pedal;

a flywheel connected to the pedal arm;

a friction brake assembly, the friction brake assembly comprising;

a push rod; and

a friction pad connected to the push rod;
