Abstract: A device for synchronously actuating and locking elevator doors, which are situated essentially one behind the other in the passage direction—such as a car door and a shaft door; the device includes entraining skids that are fastened to a first door by means of an entraining skid support and whose spacing relative to one another can be changed in order to be able to couple the first door to the second door and move the two doors together and the device is coupled to a linear drive unit that moves the doors in the opening and closing directions, characterized in that the entraining skid support has a plurality of first openings that make it possible to mount at least one, preferably both, of the entraining skids on the entraining skid support in different functional positions.

Abstract: A device for synchronously actuating and locking elevator doors, which are situated essentially one behind the other in the passage direction—such as a car door and a shaft door; the device includes entraining skids that are associated with a first driven door and whose spacing relative to one another can be changed in order to be able to couple the first door to the second door and move them together, characterized in that at least one of the entraining skids is supported in mobile fashion relative to the component, which holds it directly and is preferably embodied in the form of an entraining skid support, and toward the end of the closing movement, is secured so that it disengages from the second door, particularly by coming into contact with a stationary actuating element, which forcibly imparts a lifting movement to the at least one entraining skid.

Abstract: A door coupler provided with coupling elements actuated by means of a linkage so as to engage a counter element provided on the landing door and a locking hook that has a closed position and a released position. The release of the locking hook from the closed position to the released position is allowed when the coupling element meets the counter element. The locking hook and the coupling elements are disposed at a distance from each other.

Abstract: A door coupler (4) comprising gripping elements (14,15) moved by a linkage (2) and designed to grip a counterpart (17,18) on the landing door, and a lock catch (10) which has a closed position and an open position. The releasing movement of the lock catch (10) from the closed position into the open position is allowed when a gripping element is pressed against a counterpart.

Abstract: In the arrangement in the opening and closing of automatic elevator doors, the door coupler (20) is mounted on the car door so as to be movable in the direction of movement of the car door. The door coupler (20) is connected to a lever (21) whose first end is pivoted on the car door while its second end is pivoted on the door coupler. The power for the opening and closing of the doors is applied to the lever (21,71) via a point between its first end (21a, 71a) and second end (21b, 71b).
