Abstract

The sealing arrangement (1) for a wing (3) of a door without sill comprises an automatically lowerable rail (7) with an elastic sealing strip (9) which the lowered state of the rail seals the gap between the bottom surface (2) of the door wing and the floor (4). The sealing strip incorporates a sealing element (10) which is foamable at elevated temperatures.

Description

Für Brandschutztüren ist es bekannt, am oberen Türflügelrand und an den seitlichen Türflügelrändern bei Hitze aufschäumbare Dichtstreifen in Nuten einzukleben. Wenn die Temperatur im Spalt zwischen Türflügel und Rahmen eine Temperatur von 100°C bis 180°C übersteigt, schwellen diese Dichtstreifen auf, dichten den Spalt ab und verkeilen zusätzlich den Türflügel im Rahmen.For fire doors, it is known at the top of the door wing and Foamable on the side edges of the door in heat Glue sealing strips in grooves. When the temperature in the gap between door leaf and frame a temperature of 100 ° C to Exceeds 180 ° C, these seal strips swell, seal the Split and additionally wedged the door in the frame.

FR-A-2 433 094 beschreibt eine derartige Brandschutzdichtung. An einem Turflügel sind Dichtelemente angeordnet, die sich bei erhöhter Temperatur ausdehnen und u-förmige Metallleisten gegen den Türrahmen pressen.FR-A-2 433 094 describes such a fire-resistant seal. On a Turflügel sealing elements are arranged which expand at elevated temperature and U-shaped Press metal strips against the door frame.

WO 97/03271 offenbart verschiedene Brandschutzdichtungen für Türrahmen, welche ein in einem Kunststoffprofil angeordnetes, sich bei Wärme ausdehnendes Dichtelement aufweisen.WO 97/03271 discloses various fire protection seals for Door frame, which is arranged in a plastic profile, having a heat-expanding sealing element.

Bei einer Brandschutzsicherheit nach T30 wurde es bisher nicht als notwendig erachtet, auch den unteren Türflügelrand derart abzudichten. Dies wäre bei herkömmlichen schwellenlosen Türen auch nicht ohne weiteres möglich, weil bei schwellenlosen Türen der Spalt an der Unterseite des Türflügels aus Toleranzgründen erheblich breiter ist als an den übrigen Seiten.With a fire safety after T30 it has not been considered necessary, including the lower edge of the door in such a way seal. This would be conventional sillless doors also not readily possible, because with threshold-free doors the gap at the bottom of the door leaf for tolerance reasons is considerably wider than on the other pages.

EP-A-0 338 974 zeigt eine absenkbare Türschwellendichtung ohne Brandschutz gemäß dem Oberbegriff des Anspruchs 1.EP-A-0 338 974 shows a lowerable door sill seal without fire protection according to the preamble of claim 1.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, den Brandschutz schwellenloser Türen zu verbessern. Diese Aufgabe wird durch die Merkmalskombination der Ansprüche gelöst.The present invention is based on the object, the Improve fire safety of sillless doors. This task is achieved by the feature combination of the claims.

Die erfindungsgemässe Lösung besteht im Wesentlichen aus einer Kombination einer an sich bekannten absenkbaren Dichtschiene an der Unterseite des Türflügels von schwellenlosen Türen mit einem an sich ebenfalls bekannten Dichtelement, das jedoch im Bereich der Abdichtschiene angeordnet ist. Die Abdichtschiene überbrückt dabei den relativ grossen Spalt an der Unterseite des Türflügels, so dass das Dichtelement nicht diesen ganzen Spalt ausschäumen muss, sondern eine wesentlich geringere Höhe. Dadurch können herkömmliche, für die Seitenränder der Türflügel verwendete Dichtelemente eingesetzt werden.The inventive solution consists essentially of a Combination of a known lowerable sealing rail the underside of the door wing of thresholdless doors with one per se also known sealing element, however, in the area the sealing rail is arranged. The sealing rail bridges doing the relatively large gap at the bottom of the door, so that the sealing element does not foam this entire gap must, but a much lower height. Thereby can conventional, used for the side edges of the door leaves Sealing elements are used.

Herkömmliche, automatische Abdichtschienen an der Unterseite des Türflügels, wie sie beispielsweise in EP-A-0 338 974 offenbart sind, werden beim Schliessen der Türe automatisch abgesenkt. Dabei berührt die elastische Dichtleiste den Boden kurz vor Ende der Schliessbewegung und schleift auf dem Boden bis zum vollständigen Schliessen. Um den Verschleiss gering zu halten, wird der Winkel dieser letzten Schliessbewegung auf einen möglichst geringen Wert eingestellt. Bedingt durch die Konstruktion üblicher Absenkmechanismen ist daher die Anpresskraft der Abdichtleiste gegen den Boden relativ klein. Beim Aufschäumen des Dichtelementes im Brandfall wird nun die abgesenkte Schiene abgeschottet und verkeilt; und durch den aufgeschäumten Blähstreifen wird der Spalt zwischen Türflügel und Boden verschlossen.Conventional, automatic sealing rails at the bottom of the Door leaf, as disclosed for example in EP-A-0 338 974 are automatically lowered when closing the door. there the elastic sealing strip touches the ground just before the end the closing movement and grinds on the ground until complete Conclude. To keep the wear low, will the angle of this last closing movement on one possible set low value. Due to the construction usual Absenkmechanismen is therefore the contact pressure of the sealing strip against the ground relatively small. When foaming the Sealing element in case of fire, the lowered rail is now sealed off and wedged; and through the foamed inflatable strip the gap between the door leaf and the floor is closed.

Nachfolgend werden Ausführungsbeispiele der Erfindung anhand der Zeichnung erläutert. Die einzige Figur zeigt eine Stirnansicht einer ersten dieser Ausführungsformen.Hereinafter, embodiments of the invention with reference to the Drawing explained. The single figure shows a front view a first of these embodiments.

Die erfindungsgemässe Dichtungsanordnung 1 ist an der Unterseite 2 eines Türflügels 3 einer schwellenlosen Türe angeordnet. Sie dichtet im geschlossenen Zustand den Flügel 3 gegenüber dem Boden 4 ab. An der Unterseite 2 ist in einer Nut 5 ein Hutprofil 6 eingesetzt. Zwischen den Seitenwänden dieses Profils 6 ist eine Abdichtschiene 7 vertikal verschiebbar und wird durch einen Absenkmechanismus 8 z.B. gemäss der CH-A-631 779 oder CH-A-627 228 automatisch beim Schliessen des Türflügels 3 abgesenkt. An der Schiene 7 ist eine elastische Abdichtleiste in Form eines elastomeren Dichtungsprofils 9 aus Silicongummi, z.B. gemäss der EP-B-338 974 befestigt. Das Dichtungsprofil 9 liegt bei geschlossenem Türflügel 3 am Boden 4 an. Auf der Unterseite der Schiene 7 ist ein bei Hitze aufschäumbares Dichtelement 10 in Form eines Streifens angebracht, z.B. aufgeklebt. Das Dichtelement 10 ist im Hohlraum 11 zwischen der Schiene 7 und dem unteren Steg 12 des Dichtungsprofils 9 angeordnet und schäumt bei einer Temperatur von z.B. über 100°C bis 180°C auf. Da das Dichtelement 10 unmittelbar beim Spalt zwischen dem Boden 4 und der Unterseite 2 angeordnet ist, reagiert es rasch auf eine Temperaturerhöhung in diesem Bereich, schäumt auf, verkeilt die Schiene 7 im Hutprofil 6, und füllt den Zwischenraum zwischen dem unteren Steg der Schiene 7 und dem Boden aus. Zugleich dichten die unteren Ränder der Schenkel 13 des Dichtungsprofils 9 seitlich gegen den unteren Krümmungsbereich 14 des Hutprofils 6 ab. Die dargestellte Lösung hat zudem den Vorteil, dass die gleichen Elemente sowohl für gewöhnliche, schwellenlose Türen als auch für Brandschutztüren eingesetzt werden können. Es ist auch ohne weiteres möglich, bestehende Dichtungsanordnungen, z.B. gemäss der EP-B-338 974, nachzurüsten und so nachträglich den Brandschutz der Türe zu verbessern.The inventive seal assembly 1 is at the bottom 2 a door leaf 3 a threshold-free door arranged. she seals in the closed state, the wing 3 opposite the ground 4 off. At the bottom 2 is a hat profile 6 in a groove. 5 used. Between the side walls of this profile 6 is a Sealing rail 7 vertically displaceable and is by a lowering mechanism 8 e.g. according to CH-A-631 779 or CH-A-627 228 automatically lowered when closing the door leaf 3. At the Rail 7 is an elastic sealing strip in the form of an elastomeric Sealing profile 9 made of silicone rubber, e.g. according to the EP-B-338 974 attached. The sealing profile 9 is closed Door leaf 3 at the bottom 4 at. On the bottom of the Rail 7 is a heat-foamable sealing element 10 in Shape of a strip attached, e.g. glued. The sealing element 10 is in the cavity 11 between the rail 7 and the lower Web 12 of the sealing profile 9 is arranged and foams at a temperature of e.g. over 100 ° C to 180 ° C. As the sealing element 10 immediately at the gap between the bottom 4 and the Bottom 2 is arranged, it reacts quickly to a temperature increase in this area, foams up, wedge the rail 7 in the hat profile 6, and fills the space between the lower Bridge of the rail 7 and the floor off. At the same time, the poets write lower edges of the legs 13 of the sealing profile 9 laterally against the lower curvature region 14 of the hat profile 6 from. The The solution shown also has the advantage that the same Elements for both ordinary, no-threshold doors as well can be used for fire doors. It is also without further possible, existing sealing arrangements, e.g. according to EP-B-338 974, retrofit and so subsequently the fire protection to improve the door.

Abweichend von der dargestellten Ausführungsform kann das Dichtelement 10 auch auf den Steg 12 des Dichtungsprofils 9 innen oder aussen aufgeklebt sein. Es ist auch denkbar, das Dichtelement 10 mit dem Dichtungsprofil 9 zu koextrudieren. Falls koextrudiert wird, ist es jedoch auch möglich, das Dichtelement 10 in Form von Körnern der Extrusionsmasse beizumischen, falls die Extrusion bei relativ tiefer Temperatur erfolgen kann, z.B. wenn die Extrusionsmasse ein Zwei-Komponentengemisch ist, das bei tieferer Temperatur aushärtet. Es ist auch möglich, den Steg 12 schlauchförmig auszubilden und den Innenraum dieses Schlauches mit körnigem oder flüssigem Dichtungsmittel 10 zu füllen. Eine weitere Variante besteht darin, das Dichtelement am unteren Ende der Innenseite der Schenkel des Hutprofils 6 anzubringen, wobei diese unteren Schenkelenden eine entsprechende Stufe aufweisen.Notwithstanding the illustrated embodiment, the sealing element 10 also on the web 12 of the sealing profile 9 inside or glued on the outside. It is also conceivable, the sealing element 10 to coextrude with the sealing profile 9. If coextruded is, but it is also possible, the sealing element 10th in the form of granules to mix the extrusion mass, if the Extrusion at a relatively low temperature, e.g. if the extrusion mass is a two-component mixture that at hardens lower temperature. It is also possible, the bridge 12th form tubular and the interior of this tube to fill with granular or liquid sealant 10. A Another variant is the sealing element at the bottom to install the inside of the legs of the hat profile 6, wherein these lower leg ends have a corresponding step.
