Abstract
A manual stair step exerciser that simulates the exercise derived from climbing stairs including a support frame with a chain sprocket assembly having multiple equal spaced deployable steps thereon. A drive shaft pulley and belt assembly interconnects to an adjustable magnetic resistant flywheel for sustained user step input of kinetic energy for sustaining self-propelled tread induced motion during exercise.

A stair step device comprising:
- a frame having a pair of spaced legs;
- an upper drive shaft and a lower drive shaft supported on respective bearing sets between each leg of the pair of spaced legs;
- a plurality of interconnected step assemblies disposed between the pair of spaced legs, wherein each interconnected step assembly of the plurality of interconnected step assemblies comprise a tread, a riser, and an interconnecting plate;
- a flywheel drive shaft and support bearing assembly disposed on and extending between the pair of spaced legs in spaced relation to the upper drive shaft, a weighted flywheel disposed on a first end of the flywheel drive shaft and a flywheel pulley disposed on an opposite end of the flywheel drive shaft;
- a drive belt in communication with the flywheel pulley;
- and
- a drive belt engagement tensioner assembly on the upper drive shaft.
