Abstract
PURPOSE: To prevent falling accident of passengers from occurring by so controlling an elevator cage door as not to open the door by human power when the cage stops at the position where the cage floor is separated from the floor of a building longer than predetermined distance.
CONSTITUTION: A control circuit consists of operation power lines P, N, door open and close command relays CL, OP, door opening and closing zone contact A1, escape enable zone contact B2, and closed and open limit switches CLS, OLS opening upon fully closing and opening of the door, etc. When the elevator cage is stopped out of escape enable zone, the contact A1 is opened to deenergize the relay OP, but o close the contact B2 to thereby cause the relay CL to close the switch CLS so as to dispatch a door close command. Thus, a motor driven door opening and closing unit is operated to close the door with the result that the door cannot be opened against this force by the ordinal passengers.
