Title:
ELEVATOR CAR DOOR LOCK DEVICE AND ELEVATOR DOOR DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/038712
Kind Code:
A1
Abstract:
The present invention pertains to an elevator car door lock device that does not require the addition of a part on a landing side, and does not affect the door opening/closing performance. A car door lock hook (1) which constitutes the car door lock device is connected to a belt (6) of a door driving device (36, 37, 38, 6). When a car door (34) is driven in an opening direction by the door driving device (36, 37, 38, 6), the car door lock hook (1) is unlocked by the belt (6) that is driven. In accordance with the unlocking of the car door lock hook (1), horizontal direction movement of a door stop-side engaging element (10) is stopped by a link mechanism (19). On the other hand, when a door opening force is applied to the car door (34) without using the door driving device (36, 37, 38, 6), the door stop-side engaging element (10) provided to the car door (34) is pushed by a door engaging element (9, 13) provided to a landing door and moves in the horizontal direction to contact the car door lock hook (1), thereby unlocking the car door lock hook.
