Abstract
The skirt and deck panels of an escalator or moving walkway are edge-lapped, and are detachably secured together by a plurality of screws and quarter turn locking nuts. The deck panels are provided with a series of round, spaced-apart screw holes, and the skirt panels are provided with a plurality of elongated slots which allow flexible alignment with the screw holes. Position stops are mounted on the ends of the screws to ensure that the locking nuts will repeatedly swing to their locking positions when the panels are secured together. The panels can thus easily be disassembled and reassembled in the field by service personnel.
