A cylindrical insert within the guide circle (4) provides a diametral passage for the rotary guide strip (2) whose enfaces (6) are cased to fit into the circle (4). The circle in turn has diametrically opposed openings (5) arranged normal to the door leaf plane when the door is closed and a pressure bar between two coplanar guide circles at right angles to the turning axes extends axially just short of the casing endface (6) of the insert. A slide in each insert, forced radially outwards by a spring at right angles to the guide strip (2) passage opening, has a projection on the side facing the center of the insert reaching into the guide (2) insertion entry when the door etc. is closed. The slide projection homes into an opening in the strip provided. |
