It is possible with this device to open the cage door of a lift cage situated in the region of a storey together with a coupled-on shaft door, driven automatically in the normal case or manually in the case of current failure. If the lift cage is situated outside a storey, the cage door remains latched. A control cam (15), which is arranged at the upper end of a door leaf of the cage door, is articulatedly connected with the door drive device by way of a belt-shaped drive means. The control cam (15) causes a low-jerk opening and closing of the cage door on the closing side and of an entraining member parallelogram (18), which is necessary for the coupling of the shaft door to the cage door and connected by a pull rod (36) with the control cam (15). A latching mechanism with a pivotably borne cage door latch (46) and an electrical safety contact is likewise arranged at the upper end of the same door leaf independently of the door drive device. The cage doer latch (46) displays an actuating roller (46), which is actuated through a double lever (39) articulatedly connected with the entraining member parallelogram (18) and the control cam (15), for the unlatching when the cage stands in the door opening region of a storey.
