The device has a lever (3.1) swingably held at an inactive leaf (2) and push door leaves at a rear side of a door folding part (1.1) of an active leaf (1) during opening movement. The lever is located in a gap between facing surfaces of door leaves when the door leaves are closed and aligned normally parallel to a plane of the door leaves with respect to horizontally alignment components. A lever pivotal axis (3.2) of the door folding part of the active leaf lies far from the lever end lying away from the lever pivotal axis. The lever comprises two relatively movable parts. |
