The slatted door has guide rails (1,2) on the reverse side of the slats (12,13). Connections (3) are staggered in position from the bottom edge of the slats upwards. The connections are linked at one end to a slat; the other end is guided along the guide rails of the slat above, The upper slat pulls the lower slat underneath, The upper slat is guided into a horizontal position by means of a pulley block along a horizontal guide.
