Abstract
A moving stairway in which articulation of the steps from platform to step mode automatically positions panel members to cover the adjacent stationary skirt boards, between the tread part of each step and the riser part of the next adjacent step, and return to platform mode automatically retracts the panel members for passage through the combplate. In a preferred embodiment, the panel members additionally function as active guide elements for laterally guiding the steps through the load bearing run of the moving stairway.
