<p>An elevator car door lock has a car switch fixed to a door hanger, a fixed car latch fixed to the car or to a bracket fixed to the car, a car arm fixed to a one-side opening type door of the car via a first car shaft, and a movable car latch fixed to the door hanger via a second car shaft. When the one-side opening type door of the car is opened, the car arm is pressed by a landing vane, which is fixed to a one-side opening type door of a landing, to be rotated about the first car shaft. When rotated about the second car shaft by rotation of the car arm, the movable car latch interrupts conduction of electricity to a switch to prohibit operation of the car and releases the fixed car latch.</p> |
