Abstract

An illuminated escalator combplate has a main combplate portion and a combteeth element extending forwardly of the main portion. A series of light emitters are mounted to a forward edge of the main portion, and are aligned with a corresponding series of light pipes in the combteeth element which channel the light of the emitters from a rearward wall adjacent the main portion forward edge to an upper surface of the combteeth element where the light can be seen by escalator users and serves as a safety indicator to demarcate the intersection between the fixed combplate and the moving escalator step plates. The light emitter may be in alternately-illuminated, interleaved gangs to increase visability.
