Abstract
PURPOSE: To prevent accidents that passengers fall to an elevating course, by controlling the operation of a cage door and a door of a platform by the emitting of the commands of shutting the doors, etc. when a condition that one side of the cage door and the door of the platform opens and another side shuts is detected.
CONSTITUTION: If a gate switch 4 is in a trouble due to some reason and a contact 4a is in a short condition during the travelling of a cage 1, no abnormality occurs in the operation of the cage 1 because a relay 26 of detecting the opening of doors is already energized. When the cage 1 reaches a platform floor 9 and a cage door 2 and a platform door 10 open, a relay 27 of detecting the opening of the doors is de-energized, but contacts 27b, 26c remain as they open because the relay of detecting the opening of doors 26 remains as it is energized. Consequently, a timing relay 33 returns after a short time, and a contact 33a opens. Thus, an electromagnetic contactor 29 for opening the doors is not energized, and the door opening operation of each door 2, 10 is stopped.
