Abstract
A remote-operated elevator door safety control for holding open a door of an elevator from a remote location includes a transmitter remote from the elevator for selectively transmitting a door-open signal, a receiver at the elevator for receiving the door-open signal, and an actuator coupled with the receiver and responsive to the door-open signal to hold a door-operating mechanism in a door-open mode so as to hold the door open in response to reception of the door-open signal.

A remote-operated elevator door safety control for holding open a door of an elevator from a remote location, the elevator door having a door-operating mechanism for actuation between a door-open mode and door-close mode to move the door selectively to an open position and to a closed position, respectively, and a door-open switch for selectively holding the door-operating mechanism in the door-open mode, the safety control comprising:
- a transmitter remote from the elevator for selectively transmitting a door-open signal;
- a receiver at the elevator for receiving the door-open signal;
- and
- an actuator coupled with the receiver and responsive to the door-open signal to hold the door-operating mechanism in the door-open mode in response to reception of the door-open signal.
