Abstract:
1. A stationary exercise apparatus, comprising: a frame; a driving wheel assembly having a driving axle disposed pivotally at the frame and a driving wheel fixed to the driving axle; two treading units disposed on two opposing sides of the driving wheel assembly, respectively, and each having a transmission element fixed to an end portion of the driving axle and capable of driving the driving wheel to rotate, a first swing bar having a medially connected linkage rod connected to the transmission element and capable of swinging back and forth in the direction toward the ground and the direction away from the ground to thereby drive the transmission element to rotate, a second swing bar parallel to and spaced apart from the first swing bar, and a pedal, the first and second swing bars having an end pivotally connected to the pedal and another end pivotally connected to the frame; and a flywheel assembly having a driven wheel driven by the driving wheel assembly to start rotating at an inertial operating speed higher than a rotation speed of the driving wheel assembly, such that the driven wheel rotating at the inertial operating speed drives the treading units to swing alternately back and forth in the direction toward the ground and the direction away from the ground and relative to the frame.
