ABSTRACT:
An escalator in which the lateral edge of each step is provided with a resilient, cleated demarcation strip. The outermost cleat of the demarcation strip is flexibly and integrally hinged to the remaining portion of the demarcation strip, and is movable from an unbiased position towards, and away from the adjacent skirt panel, to first and second stops, respectively. The first and second stops assure long life in flexure, and the first stop limits the forces which can be applied to the skirt via the cleat. In another embodiment of the invention, the surfaces of the step-skirt demarcation strips which are exposed to the passengers are provided with a surface configuration which resists sliding movement of an object towards the skirt panel.
