Fixtures () at a doorway () of a landing () are formed integrally with a door frame (). The fixtures include electronic modules () and energy storage devices (). Power may be supplied by a generator () rotated by a pinion () in response to a rack () on a hoistway door (), or by electrical contacts () disposed on the hoistway side of the door frame which touch contacts () on an elevator car door () when the door is open, thereby receiving power over a line () from the elevator car; or power may be provided by an inductive coupler (). The fixtures () may be within the profile of the door frame (), or extend outwardly from the profile of the door frame ().

Wireless elevator hall fixtures integral with hall door frame

Elevator system hall fixtures such as lanterns, hall call button switches and lights, gongs, and floor position indicators are connected to a controller via wireless transceivers. The controller can be a system, group, and/or car controller. A low power wireless system connects all fixtures on one hallway, with a higher power wireless system connecting each hallway with the appropriate controller.

Two-part wireless communications system for elevator hallway fixtures

A wireless safety chain for an elevator system includes a base transceiver connected to a system controller. A plurality of safety chain components each includes a physical sensor such as a switch, and a wireless transceiver. The physical sensor monitors the component status. The wireless transceiver communicates among the other safety chain components and the system controller. The wireless safety chain preferably employs a token scheme, where a token is sent from the base transceiver to one component, which in turn sends the token to another component, and so on, until the token returns to the base transceiver. Failure of the token to return to the base transceiver in a predetermined amount of time signals that the elevator system is unsafe.
