STAIR EXERCISER APPARATUS

A stair exerciser apparatus includes a frame having a pair of inclined supports, a drive mechanism, and a plurality of stairs coupled to the drive mechanism for traveling around the pair of inclined supports. The driving mechanism has an upper shaft, a lower shaft and at least one drive chain mounted around the upper shaft and the lower shaft. A clutch mechanism is coupled to the upper shaft or the lower shaft of the drive mechanism. A flywheel is operationally coupled to the clutch mechanism, where the clutch mechanism couples the motion of the stairs to the rotation of the flywheel when the stairs are driven in a downward direction, and where the clutch mechanism decouples the motion of the stairs from the rotation of the flywheel when the stairs cease to be driven in the downward direction.
