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.
