Device for a lift system for actuating at least one cabin or shaft door is provided with a coupling mechanism which can be fastened to a moveable cabin door of a cabin. In addition, a plate unit co-operating with the coupling mechanism is provided which can be fixed onto a shaft door on the respective story. The coupling mechanism has a coupling element that can be adjusted transversely to the latter or to the cabin door and can be moved from a drawn back position into a position coupled with a counter-element of the plate unit. This adjustable coupling element and the counter-element of the plate unit are advantageously each magnetic, by means of which sufficient adhesive force can be generated in the coupled position. This device enables proper functioning during operation of a lift system, even if there are breakdowns.

The present invention includes a height raising member body mountable to an upper end of a frame disposed above an entrance of a car that moves up and down through an elevator shaft, in which a rail for guiding a car door in an opening and closing direction and a pulley for use in opening and closing drive of the car door are mounted to the frame. The height raising member body characteristically includes: a base part connectable to the frame; and a supporting part capable of supporting the motor at a position upward away from the base, the motor being configured to drive the pulley via a belt.

An elevator system includes an elevator car with a car door arranged on the elevator car. The car door includes at least one door leaf movable in a translatory manner, a guide rail fastened to the elevator car, which guide rail forms a guide for the translatory movement of the door leaf, and a drive assembly for driving the door leaf. The drive assembly is movably mounted on the elevator car.

An elevator car door control system includes a clutch and an interlock assembly. The clutch may include a stationary base and a slidable base movably attached to the stationary base. The stationary base may be adapted for attachment to a car door of an elevator car. The interlock assembly may include a locking arm operatively connected to the slidable base of the clutch and moveable from a locked position preventing translation relative to the elevator car to an unlocked position. When the car door is in a closed position, a door opening sequence may commence causing the slidable base to move relative to the car door, but the car door will only open if the slidable base presses against an object, such as a roller on a hoistway door, in which case the locking arm of the interlock assembly moves from the locked to the unlocked position.

An elevator car for an elevator installation may include at least one side wall having a doorway and an elevator car door. For opening and/or closing the doorway, the elevator car door can be moved at least partially parallel to the side wall on an outside of the side wall. In opening and/or closing, the elevator car door can be moved at least partially in a direction perpendicular to the side wall. In the closing process, the elevator car door can be at least partially sunk in the doorway. A coupling element may couple the elevator car door to a shaft door in at least one of opening or closing the elevator car door.
