Door coupler with an actuation that permits it to be flexibly positioned

摘要

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.

1. A device for synchronously actuating and locking elevator doors, which are situated essentially one behind the other in a passage direction—such as a car door and a shaft door; the device comprising:
a plurality of entraining skids that are associated with a first driven door and a spacing of the entraining skids relative to one another can be changed in order to be able to couple the first door to a second door and move the first door and the second door together, wherein at least one of the entraining skids is supported in mobile fashion relative to an entraining skid support that holds the at least one entraining skid directly, and toward an end of a closing movement, the at least one entraining skid is secured so that it disengages from the second door by coming into contact with a stationary actuating element, which forcibly imparts a lifting movement to the at least one entraining skid; wherein the entraining skid support is coupled directly to a linear drive unit or its belt, and the entraining skid support is connected to a carriage movable relative to a door panel so that the entraining skid support is able to move in translatory fashion relative to the carriage, so that when the carriage of the door panel has come to a stop after the door has been completely closed, the linear drive unit or its belt can continue moving the entraining skid support a certain distance further into its final closed position; and one of the entraining skids that does not interact directly with the actuating element controls the opening and closing movement of a car door bolt, and moves a slider that is able to move in a completely or at least predominantly translatory fashion and that is in turn coupled to the car door bolt, wherein the slider is supported on a side of the entraining skid support oriented away from the entraining skids.
