Abstract
The present application includes a system configured to provide transportation services between two different elevations. Individuals may be transported upward or downward within a circular stairway. The system includes a series of fixed stairs coupled to a housing. It also includes a series of corresponding movable stairs coupled to a central shaft. The movable stairs are configured to move in relation to the central shaft and are operable to provide transportation between two fixed stairs. An individual is lifted and translated between the fixed stairs as the movable stairs transition between a plurality of positions.

An escalator system for transporting an individual between different elevations, comprising:
- a central shaft configured to raise, lower, and rotate relative to a fixed shaft;
- a fixed stair coupled to an outer housing, the fixed stair including a plurality of fins, a stairwell defined between the fixed shaft and the outer housing;
- and
- a movable stair coupled to the central shaft, the movable stair configured to move in accordance to the central shaft, the movable stair including a plurality of fins, the fins of the movable stair and the fins of the fixed stair are configured to engage and pass between one another;
- wherein the motion of the central shaft is configured to rotate the movable stair around the fixed stair;
- and
- wherein an individual is transported from the fixed stair to an adjacent fixed stair by the motion of the movable stair.
A method of transporting an individual between different elevations, comprising:
- aligning a pair of shafts, a central shaft configured to raise, lower, and rotate relative to a fixed shaft, the central shaft configured to move in relation to the fixed shaft;
- coupling a fixed stair to an outer housing, the fixed stair including a plurality of fins;
- coupling a movable stair to the central shaft, the movable stair configured to move in accordance to the central shaft, the movable stair including a plurality of fins;
- and
- moving the movable stair around a portion of the fixed stair as the central shaft moves, the fins of the movable stair and the fins of the fixed stair are configured to engage and pass between one another;
- wherein an individual is transported between fixed stairs by the motion of the movable stair.
