STAIR CLIMBER APPARATUSES AND METHODS OF OPERATING STAIR CLIMBER APPARATUSES

摘要

Stair climber apparatuses have a frame having an inclined support that extends from a bottom portion to a top portion; a plurality of stairs that are connected together in series and travel in a loop around the inclined support; an electric motor; and a control circuit that controls a speed of the electric motor and an output direction of the electric motor. The electric motor is operatively connected to the plurality of stairs so as to move the plurality of stairs in an upward direction along the inclined support and so as to alternatively move the plurality of stairs in an opposite, downward direction along the inclined support.
