ABSTRACT:
The invention is relating to a coupling device for elevator car (5) and landing doors of the kind comprising moving cams (3) integral with the car door (5) and driving the landing door in front of a story landing by means of a coupling plate integral therewith and engaging with the cams (3), locking it mechanically and electrically upon door closure to allow the subsequent drive of the car, wherein said cams (3) are movably mounted with a variable distance from each other on the car door (5), independently from the car door drive belt (19), and a part (7) is provided to drive the cams (3) with a variable distance, which part (7) is mounted on the car door (5) and connected to the drive belt (19) and to one of the cams (3) to drive it towards and away from the other cam (3) with a large displacement relative to a small overtravel drive of the belt (19), in order to respectively allow to unlock the coupling plate and its landing door drive coupling when the doors open and to lock it when they close.
