Exercise device with magnetic braking system
First Claim
1. An exercise device usable by a user in performing an exercise, the exercise device comprising:
- a flywheel rotatable during the performance of the exercise by the user; and
a braking system that regulates the speed of the flywheel, the braking system comprising a magnetic member movable between a first position with respect to the flywheel and a second position that is closer to the flywheel than the first position, the magnetic member being positioned adjacent to the outer circumference of the flywheel, and the magnetic member being movable substantially parallel to the axis of rotation of the flywheel between the first position and the second position; and
a selectively inclinable treadbase;
wherein the magnetic member is operable to move relative to the first and second positions in response to acceleration of the flywheel produced by movement of the user on the treadbase.

Abstract
A selectively inclining hiking exercise apparatus supports a user ambulating thereon. The selectively inclining hiking exercise apparatus includes a support base and a treadbase that selectively inclines with respect to the support base. The treadbase includes a motor for driving an endless belt upon which the user ambulates. The treadbase also includes a magnetic braking assembly for regulating the speed of the endless belt to prevent the endless belt from moving at a rate that is faster than the rate at which the treadbase motor is driving the endless belt. The magnetic braking assembly includes a magnet that selectively moves relative to the treadbase flywheel along a threaded lead screw to provide the braking force.

15. An exercise device usable by a user in performing an exercise, the exercise device comprising:
-
a flywheel rotatable during the performance of the exercise by the user; a braking system that regulates the speed of the flywheel, the braking system comprising a magnetic member that is movable between a first position with respect to the flywheel and a second position that is closer to the flywheel than the first position; and control circuitry that monitors an operating parameter of the exercise device, wherein the control circuitry causes the magnetic member to move between the first position and the second position in response to acceleration of the flywheel produced by the weight of the user applied to an inclined surface of the exercise device. - View Dependent Claims (16)

17. An exercise device usable by a user in performing an exercise, the exercise device comprising:
-
a flywheel rotatable during the performance of the exercise by the user; and a braking system that regulates the speed of the flywheel, the braking system comprising a magnetic member mounted on a lead screw and a guide rod, the magnetic member being movable between a first position with respect to the flywheel and a second position that is closer to the flywheel than the first position, and wherein movement of the magnetic member between the first position and the second position is along a length of the lead screw; and an inclined surface on which the user may exercise; wherein the magnetic member is operable to move relative to the first and second positions in response to the user applying a force parallel to the inclined surface.
