Abstract

An escalator system includes a protective flange assembly along edges of the steps having step flanges. In one example, a first step flange member is adjacent each edge of each step and moves with the step along the escalator path. The first panel member remains stationary relative to the step along the entire path. A second panel member is associated with a corresponding link in the drive chain and remains stationary relative to the link along the entire path of the escalator. The first panel members and second panel members cooperate to provide a continuous barrier along each edge of the steps along the escalator path.
