Abstract
An exercise device comprises first and second crank arms configured to rotate 180 degrees out of phase with respect to one another about a first axis; a track; first and second foot links, first and second footpads carried by the first and second foot links between the first link portion and the second link portion and first and second front arms. Each of the first and second foot links has a first link portion that moves along the track while pivoting. Each of the first and second front arms has a first arm portion pivotally coupled to one of the foot links and a second arm portion pivotally coupled one of the crank arms. In one embodiment, a disc rotates in response to movement of the first foot link along the track, wherein a magnet facing the disc forms an eddy brake.
Claims20
An exercise device comprising:
- first and second crank arms configured to rotate 180 degrees out of phase with respect to one another about a first axis;
- at least one track;
- first and second foot links, each of the first and second foot links having a first link portion configured to move along the at least one track while pivoting and a second link portion;
- first and second footpads carried by the first and second foot links between the first link portion and the second link portion and
- first and second front arms, each of the first and second front arms having a first arm portion pivotally coupled to the second link portion of one of the foot links and a second arm portion pivotally coupled one of the crank arms.
The exercise device of claim 6 further comprising a second adjustable resistance source at least one of the first and second foot links to resist movement of the first link portion of the first and second foot links along the least one track.
An exercise device comprising:
- at least one track;
- first and second foot links, each of the first and second foot links having a roller configured to roll along the at least one track;
- a disc to the roller to rotate with the roller;
- and
- a magnet facing the disc and carried by one of the first and second foot links, wherein the magnet and the disc cooperate form an Eddy brake resisting movement of the first and second foot links along at least one track.
A method comprising:
- moving a first portion of a foot link supporting a foot pad along a track;
- pivoting a second portion of the foot link about a pivot joint between the second portion of the foot link and a first portion of a front aim;
- and
- rotating a second portion of the front arm with a crank arm.
