Abstract
An eccentric idler is disclosed. One application of the eccentric idler is on a stationary exercise cycle. The cycle may include an eccentric driver or driven shaft rotating a belt or chain. The idler is coupled to the cycle and is configured to rotate eccentrically in contact with the belt or chain. The stationary exercise cycle of various embodiments is configured to generate reciprocating motion, thereby providing users with a vibratory exercise experience.
Claims62
A cycle comprising:
- a frame;
- an axle disposed in the frame and configured to eccentrically rotate relative to the frame;
- a driving wheel coupled to the axle;
- a flywheel coupled to the frame so as to rotate about an axis, the axis being spaced from the axle along a line;
- a belt contacting the driving wheel and the flywheel, a first portion of the belt being disposed in a region above the line and having a length, and a second portion of the belt being disposed in a region below the line and having a length;
- and
- an idler coupled to the frame and configured to rotate eccentrically, at least a portion of the idler contacting the belt so that the length of the belt in the first region and the length of the belt in the second region stay generally constant at least when the belt drives the flywheel.
