Abstract
A vertical stepping machine includes a frame, a crank wheel connected to the frame, a crank arm extending away from a rotational axis of the crank wheel, and a pedal beam connected to the crank arm. A linkage assembly is connected to the frame at a fixed frame location and to the pedal beam at a fixed pedal beam location. A first linkage member of the linkage assembly has a length that forces the pedal beam to travel along an elliptical path as the crank wheel rotates.
Claims20
A vertical stepping machine, comprising:
- a frame;
- a crank wheel connected to the frame, the crank wheel having an axis of rotation;
- a crank arm extending away from the axis of rotation;
- a pedal beam connected to the crank arm;
- a linkage rotatably connected at a first end of the linkage to the frame at a fixed frame location and to the pedal beam at a second end of the linkage at a fixed pedal beam location;
- and
- a first linkage member of the linkage exerting a force on the pedal beam to change an angular orientation of the pedal beam relative to the frame when the crank wheel rotates, wherein the first linkage member is stationary with respect to the pedal beam.
