Verschlussklappe nach einem der Ansprüche 1-4, dadurch gekennzeichnet, dass die freie Kante der Dichtlippe (9) auch in der Schliessstellung noch frei steht.5. Closure flap according to one of claims 1-4, characterized in that the free edge of the sealing lip (9) is still free even in the closed position. Die Erfindung betrifft eine Verschlussklappe für lufttechnische Anlagen, mit in einer Ebene parallel zueinander angeordneten, in Schliessstellung mit ihren Längskanten aneinanderschliessenden Klappengliedern, die in einem Rahmen um ihre Längsachse drehbar gelagert sind und an einer der in Schliessstellung jeweils aneinanderschliessenden beiden Klappengliedkanten mit einem elastischen Dichtungsprofil versehen sind.The invention relates to a closure flap for ventilation systems, with flap members arranged parallel to one another in a plane, which in the closed position connect with their longitudinal edges, which are mounted in a frame so as to be rotatable about their longitudinal axis and are provided with an elastic sealing profile on one of the two flap member edges which connect with one another in the closed position are. Als Aufgabe liegt der Erfindung zugrunde, die Sicherheit der Abdichtung bei geringer Stellkraft zu erhöhen.The object of the invention is to increase the security of the seal with a low actuating force. Gemäss der Erfindung ist zu diesem Zweck bei einer Verschlussklappe der eingangs bezeichneten Art vorgesehen, dass das Dichtungsprofil die Berührungsfläche für die Gegenkante an einer nur einseitig an einer Verankerung sitzenden Lippe aufweist.According to the invention, it is provided for this purpose in a closure flap of the type described at the outset that the sealing profile has the contact surface for the opposite edge on a lip that is only seated on one side on an anchorage. Sind die Klappenglieder gegensinnig bewegt, so liegt die freie Kante der Lippe vorzugsweise in Schliessrichtung des Klappenglieds vorn. Bei umgekehrter Ausrichtung staucht dieIf the flap members are moved in opposite directions, the free edge of the lip is preferably at the front in the closing direction of the flap member. If the orientation is reversed, the compresses Gegenkante, die in der letzten Phase des Schliessvorgangs mit ihrer Rundung etwas über die Lippe streift, die Lippe leicht an.Opposite edge, which in the last phase of the closing process with its curve touches something over the lip, the lip lightly. Sind die Klappenglieder gleichsinnig bewegt, so liegt im gleichen Sinne vorzugsweise die andere, an der Verankerung s sitzende Seite der Lippe in Schliessrichtung vorn.If the flap members are moved in the same direction, the other side of the lip, which is seated on the anchorage s, is preferably in the front in the closing direction in the same sense. Ferner ist es vorteilhaft, wenn die freie Kante der Dichtlippe dem Luftdruck entgegen liegt, weil dieser dann unter die Lippe fassen und sie an die Gegenkante andrücken kann. Soweit das mit der für gegensinnig bewegte Klappenglieder vorgeschlage-10 nen Anordnung der Lippe nicht vereinbar ist, wird man allerdings dieser in der Regel den Vorrang geben.Furthermore, it is advantageous if the free edge of the sealing lip is opposed to the air pressure, because this can then reach under the lip and press it against the opposite edge. Insofar as this is not compatible with the arrangement of the lip proposed for flap members moved in opposite directions, this will generally be given priority. Die freie Kante der Dichtlippe sollte auch in der Schliessstellung noch frei stehen und nicht durch irgendeine Berührung von hinten abgestützt sein, damit ihre Nachgiebigkeit und Anis passungsfähigkeit voll erhalten bleibt.The free edge of the sealing lip should also be free in the closed position and not be supported by any kind of contact from behind so that its flexibility and ability to fit is fully retained. Anhand eines Ausführungsbeispiels sei die Erfindung weiter erläutert.The invention will be explained further using an exemplary embodiment. Die Zeichnung zeigt inThe drawing shows in Fig. 1 einen Teilquerschnitt durch eine Gliederklappe, 20 Fig. 2 einen Ausschnitt aus Fig. 1 in Öffnungsstellung undFig. 1 shows a partial cross section through a link flap, 20 Fig. 2 shows a detail from Fig. 1 in the open position and Fig. 3 denselben Ausschnitt in Schliessstellung der Klappe.Fig. 3 the same detail in the closed position of the flap. In einem nicht gezeichneten, rechteckigen Rahmen aus Blechprofil sind in einer Ebene auf parallelen Achsen, die bei 1 25 angedeutet sind, Klappenglieder 2 gelagert. Sie sind mittels eines Antriebs bekannter Art aus der in der Zeichnung dargestellten Verschlussstellung, in der sie aneinanderschliessen, in Pfeilrichtung um 90° in ihre Öffnungsstellung verdrehbar.In a non-illustrated, rectangular frame made of sheet metal profile flap members 2 are mounted in a plane on parallel axes, which are indicated at 1 25. By means of a drive of a known type, they can be rotated through 90° in the direction of the arrow into their open position from the closed position shown in the drawing, in which they close together. Die Klappenglieder sind hergestellt aus zwei längsweise 30 leicht geknickten und an ihren Rändern durch Fälze 3 und 4 verbundenen Blechstreifen 5 und The flap members are made of two lengthways 30 slightly bent and connected at their edges by folds 3 and 4 sheet metal strips 5 and 6. Der Blechstreifen weist neben dem Falz 4 eine Nut 7 auf.6. The metal strip has a groove 7 next to the fold 4 . Der Falz 3 liegt in der durch die Achse 1 gehenden Querschnittslängsachse des Klappengliedes und ist radial nach aussen 35 gerichtet. Die Nut liegt auf der anderen Seite der Achse 1 mit ihrer Mittellinie ebenfalls auf der Querschnittslängsachse. Sie enthält ein in sie eingedrücktes rechteckiges Gummiprofil 8, von dem eine Dichtlippe 9 absteht.The fold 3 lies in the cross-sectional longitudinal axis of the flap member passing through the axis 1 and is directed radially outwards 35 . The groove is on the other side of the axis 1 with its center line also on the cross-sectional longitudinal axis. It contains a rectangular rubber profile 8 pressed into it, from which a sealing lip 9 protrudes. Die Dichtlippe 9 sitzt mit ihrer einen Seite etwa rechtwinklig 40 auf dem rechteckigen Profil 8 und ist dann bis annähernd in die Tangentialrichtung umgebogen. In der Schliesstellung gemäss Fig. 3 ist sie in die Nut 7 hineingedrückt; auch hier stösst ihre freie Kante jedoch nirgends an.The sealing lip 9 sits with its one side approximately at right angles 40 on the rectangular profile 8 and is then bent approximately in the tangential direction. In the closed position according to FIG. 3, it is pushed into the groove 7; here too, however, its free edge does not touch anywhere. Die Schliessrichtung der Klappenglieder 2 ist durch Pf eüe 45 angegeben. Der Druck kommt in der Darstellung von rechts.The closing direction of the flap members 2 is indicated by arrows 45 . The pressure comes from the right in the illustration. CC 1 Blatt Zeichnungen1 sheet of drawings
