Elevator door control apparatus

An elevator door control apparatus comprising:

• at least one door safety device for detecting whether elevator doors are safe;
• an elevator control circuit for outputting a door-open/close command;
• and
• a door control circuit for controlling the opening/closing of doors on the basis of a door-open/close command issued from the elevator control circuit and for outputting a door reversal request to the elevator control circuit upon reception of the operation signal of the door safety device while the doors are being closed on the basis of a door-close command speed pattern from the elevator control circuit, for switching the door speed command pattern to a brake pattern from the door-close command speed pattern, for thereafter switching the door speed command pattern from the brake pattern to the door-open command speed pattern when the door-open command is received from the elevator control circuit and for generating a constant speed door-close command speed pattern when a door-open command is not generated by said elevator control circuit within a predetermined time period beginning when the door speed command pattern is changed from the door-close command speed pattern to the brake pattern and ending when the doors reach a predetermined low speed.
