Abstract
Several embodiments of a foldable and transportable elliptical exercise machine are disclosed which include pedal arms and optional corresponding load bearing rails that are folded to an upright position for storage and transportation. The pedal arms are shaped to optimize user safety and exercise productivity. The device housing can include movable portions that optimize safety during use, but accommodate the pedal arms in the upright and folded position.
Claims83
An exercise device comprising:
- a frame;
- a crank pulley having an axis rotatably mounted on the frame;
- a pair of opposing crank arms, each crank arm having a first end fixed to the crank pulley axis and a second end extending radially outwardly from the axis in a direction opposite the other crank arm;
- a pair of pedal arms each having a first end rotatably joined to the second end of a respective crank arm, a central portion extending rearwardly from the pedal arm first end and a second end rearward of the central portion, and the pedal arms being pivotable between a use position and an upright folded position;
- and a pair of rails movably joined to the frame and each having a load bearing surface for supporting the second end of a respective pedal arm and wherein the rails are movable between a use position and a compact, non-use position.
