The door opening is defined by a floor, vertical walls and a top. At least one guide-part (22,24) is positioned on at least one door-leaf (10,12). A fixed counter-guide (18,20) is located beneath the top edge of a threshold (34,36), and has a guide groove (26,28) open towards the lift-shaft. The counter-guide is formed in a transition part above the guide groove and acts as a deflector. |
