Abstract

Fixtures (22, 27) at a doorway (13) of a landing (14) are formed integrally with a door frame (17, 17a). The fixtures include electronic modules (42, 46, 54) and energy storage devices (43, 47, 55). Power may be supplied by a generator (32) rotated by a pinion (34) in response to a rack (35) on a hoistway door (20), or by electrical contacts (58) disposed on the hoistway side of the door frame which touch contacts (65) on an elevator car door (63) when the door is open, thereby receiving power over a line (66) from the elevator car; or power may be provided by an inductive coupler (70). The fixtures (22, 27) may be within the profile of the door frame (17), or extend outwardly from the profile of the door frame (17a).
