Description

Die vorliegende Erfindung betrifft eine automatische Dichtung mit einem Gehäuseprofil, einem Mechanismus und einer Dichtleiste, wobei die Dichtleiste über den Mechanismus mit dem Gehäuseprofil verbunden ist, wobei die Dichtleiste mittels des Mechanismus gegenüber dem Gehäuseprofil in einer Querrichtung zum Gehäuseprofil aus einer Ruhestellung in eine Dichtstellung bewegbar ist und wobei in der Ruhestellung und der Dichtstellung wenigstens ein Hohlraum zwischen dem Gehäuseprofil und der Dichtleiste vorgesehen ist.The present invention relates to an automatic seal with a housing profile, a mechanism and a sealing strip, wherein the sealing strip is connected via the mechanism with the housing profile, wherein the sealing strip by means of the mechanism relative to the housing profile in a transverse direction to the housing profile from a rest position into a sealing position movable is and wherein at least one cavity between the housing profile and the sealing strip is provided in the rest position and the sealing position.

Automatische Dichtungen dieser Art sind zum Beispiel in den Dokumenten EP 1 365 098 B1 , EP 1 193 363 B1 und EP 1 233 137 A2 offenbart. Diese und andere Dichtungen der eingangs genannten Art werden genutzt, um Türen abzudichten. Die Dichtungen sind dazu entweder an einem Türblatt oder einem Türrahmen angebracht. Beim Schließen der Tür wird der Mechanismus der Dichtung betätigt, wodurch die Dichtleiste in die Dichtstellung bewegt wird, in welcher die Dichtleiste an einem Fußboden, einem Türrahmen, einer Decke oder Wand bzw. an einem Türblatt anliegt.Automatic seals of this type are for example in the documents EP 1 365 098 B1 . EP 1 193 363 B1 and EP 1 233 137 A2 disclosed. These and other seals of the type mentioned are used to seal doors. The seals are attached to either a door leaf or a door frame. When closing the door of the mechanism of the seal is actuated, whereby the sealing strip is moved to the sealing position in which the sealing strip rests against a floor, a door frame, a ceiling or wall or on a door leaf.

Aus den Dokumenten EP 1 365 098 B1 und EP 1 193 363 B1 ist außerdem bekannt, dass in Dichtleisten, nämlich zwischen elastischen Dichtungsprofilen und Halteprofilen intumeszierende Materialien vorgesehen sind, welche im Falle eines Brandes aufgrund der Hitze expandieren. Durch die Expansion des Materials können Spalte rauchfest verschlossen werden.From the documents EP 1 365 098 B1 and EP 1 193 363 B1 is also known that intumescent materials are provided in sealing strips, namely between elastic sealing profiles and retaining profiles, which expand in the event of a fire due to the heat. Due to the expansion of the material, gaps can be closed smoke-proof.

Die Rauchdichtigkeit mit einer automatischen Dichtung gemäß den vorgenannten Dichtungen im Brandfall ist grundsätzlich gewährleistet, jedoch sind neben dem Einbringen des intumeszierenden Materials in die Dichtleiste weitere Maßnahmen notwendig, dass im Brandfall die gewünschte Rauch- und Branddichtigkeit für den erforderlichen Zeitraum erhalten bleibt. Eine Maßnahme, die bei einer Halterung der Dichtung mittels an den Enden des Dichtungsprofils vorgesehenen Befestigungswinkeln sinnvoll ist, ist die Befestigung des Gehäuseprofil mit gegenüber einer normalen Dichtung verstärkten Komponenten (Befestigungswinkel und Schrauben). Ein weiteres Problem kann entstehen, wenn die Menge des intumeszierenden Materials und die Dichtungsleiste, in welcher das intumeszierende Material untergebracht ist, nicht aufeinander abgestimmt sind. Es kann dann vorkommen, dass durch ein zuviel an intumeszierendem Material das elastische Dichtungsprofil im Brandfall aufgrund der Expansion des intumeszierenden Materials aufplatzt oder reißt und die Dichtung nicht mehr wie beabsichtigt abdichtet. Eventuell ergeben sich gerade dadurch Spalte, durch welche Rauch hindurchtreten kann. Intumeszierendes Material kann außerdem aus dem abzudichtenden Bereich heraustreten und geht dann für die beabsichtigte branddichte Abdichtung verloren, d.h. dass die Widerstandskraft der Tür gegen den Brand beeinträchtigt sein kann.The smoke-tightness with an automatic seal according to the aforementioned seals in case of fire is basically guaranteed, but in addition to the introduction of the intumescent material in the sealing strip further measures necessary that in case of fire, the desired smoke and fire-tightness for the required Period is preserved. A measure that is useful in a holder of the seal by means provided at the ends of the sealing profile mounting brackets, is the attachment of the housing profile with respect to a normal seal reinforced components (mounting bracket and screws). Another problem can arise when the amount of intumescent material and the weather strip in which the intumescent material is housed are not matched. It may then happen that the elastic sealing profile bursts or tears in the event of fire due to the expansion of the intumescent material and seals the seal no longer as intended by too much intumescent material. This may result in gaps through which smoke can pass. Intumescent material may also leak out of the area to be sealed and then be lost to the intended fire-proof seal, ie the resistance of the door to fire may be compromised.

Außerdem muss bei einer Dichtung, wie sie in den genannten Dokumenten offenbart ist, berücksichtigt werden, dass die Verformbarkeit des Dichtungsprofils bei einer Dichtung mit in der Dichtleiste vorgesehenem intumeszierendem Material geringer ist als bei der gleichen Dichtleiste ohne intumeszierendes Material, da das als fester Körper vorliegende intumeszierende Material nicht oder nur wenig elastisch ist.In addition, it must be taken into account in a seal, as disclosed in the cited documents, that the deformability of the sealing profile in a seal provided in the sealing strip intumescent material is lower than in the same sealing strip without intumescent material, since this is present as a solid body intumescent material is not or only slightly elastic.

Die genannten Einschränkungen ziehen einen Aufwand nach sich, der eine sorgfältige Planung bei der Verwendung der Dichtungen nach sich zieht. Es besteht ein Bedürfnis für eine rauchdichte Dichtung, die weniger oder keine besondere Planung erforderlich macht.The above restrictions entail an expense that requires careful planning when using the seals. There is a need for a smoke tight seal that requires less or no special planning.

Ferner ist es bekannt, dass das Gehäuseprofil und die Dichtleiste in besonderen Fällen bei einer äußeren Anregung Resonanzen hervorrufen können, die sich ungünstig auf das Schalldämmverhalten der Dichtung insgesamt auswirken können. Auch ein solches Verhalten gilt es zu verhindern.Furthermore, it is known that the housing profile and the sealing strip can cause resonances in special cases at an external excitation, which can adversely affect the overall sound insulation behavior of the seal. Even such behavior should be prevented.

Beide Bedürfnisse können mit einer erfindungsgemäßen Dichtung gelöst werden, bei der der wenigstens eine Hohlraum zwischen dem Gehäuseprofil und der Dichtleiste zumindest zum Teil mit wenigstens einem Füllstoff gefüllt ist. Dieser Füllstoff kann insbesondere ein Dämmstoff und/oder ein intumeszierender Füllstoff sein. Der Füllstoff ist insbesondere in dem Hohlraum eingebracht, der sich in Richtung der Bewegung der Dichtleiste aus der Dichtstellung in die Ruhestellung hinter der Dichtleiste befindet. In der Regel erstreckt sich dieser Hohlraum zwischen einem Steg eines im wesentlichen U-förmigen Gehäuseprofils und einem Steg eines H-förmigen oder U-förmigen Halteprofils der Dichtleiste. Der Hohlraum kann auf bis zu drei Seiten von dem Steg und von Schenkeln des H-förmigen Halteprofils begrenzt sein.Both needs can be solved with a seal according to the invention, in which the at least one cavity between the housing profile and the sealing strip is at least partially filled with at least one filler. This filler may in particular be an insulating material and / or an intumescent filler. The filler is introduced in particular in the cavity, which is located in the direction of movement of the sealing strip from the sealing position to the rest position behind the sealing strip. As a rule, this cavity extends between a web of a substantially U-shaped housing profile and a web of an H-shaped or U-shaped retaining profile of the sealing strip. The cavity may be bounded on up to three sides by the web and legs of the H-shaped retaining profile.

Ein in dem Hohlraum zwischen dem Gehäuseprofil und der Dichtleiste eingebrachter Füllstoff kann das System aus Gehäuseprofil, Mechanismus und Dichtleiste so verstimmen, dass heißt die Eigenfrequenzen so verändern, dass eine Anregung im Bereich der Eigenfrequenzen bei einer normalen, bestimmungsgemäßen Verwendung der Dichtung verhindert ist.A introduced in the cavity between the housing profile and the sealing strip filler can detune the system of housing profile, mechanism and sealing strip so that change the natural frequencies so that excitation in the range of natural frequencies in a normal, intended use of the seal is prevented.

Ein weiterer Vorteil der Anordnung des Füllstoffes in dem beschriebenen Hohlraum ist, dass die Dichtleiste bei einer Expansion eines mit Druck expandierenden intumeszierenden Füllstoffes in die Richtung der Dichtung bei einer Bewegung aus der Ruhestellung in die Dichtstellung gedrückt wird. Die Expansion des intumeszierenden Füllstoffes verschließt damit nicht nur die Dichtung gegen einen Rauchdurchtritt zwischen Gehäuseprofil und Dichtleiste. Die Expansion drückt zusätzlich die Dichtleiste in ihre Dichtstellung und sorgt damit für ein großflächiges Anliegen der Dichtleiste gegen ihre Auflagefläche, auch wenn der Mechanismus z.B. aufgrund von Hitzeeinwirkung versagen sollte. Ein Platzen oder Reißen des Dichtungsprofils aufgrund der Expansion des intumeszierenden Materials ist unmöglich, da das intumeszierende Material nicht in dem Dichtungsprofil angeordnet ist.Another advantage of the arrangement of the filler in the cavity described is that the sealing strip is pressed in an expansion of a pressure-expanding intumescent filler in the direction of the seal in a movement from the rest position to the sealing position. The expansion of the intumescent Filler thus not only seals the seal against a passage of smoke between the housing profile and sealing strip. The expansion also presses the sealing strip in its sealing position and thus ensures a large-scale concern of the sealing strip against its support surface, even if the mechanism should fail, for example due to heat. Bursting or tearing of the sealing profile due to the expansion of the intumescent material is impossible because the intumescent material is not located in the sealing profile.

Bei einer erfindungsgemäßen Dichtung kann der Füllstoff ganz oder teilweise an dem Gehäuseprofil befestigt sein. Alternativ ist es möglich, den Füllstoff oder einen Teil des Füllstoffes an der Dichtleiste anzubringen.In a seal according to the invention, the filler may be wholly or partially attached to the housing profile. Alternatively, it is possible to attach the filler or a part of the filler to the sealing strip.

Der in einer erfindungsgemäßen Dichtung angeordnete Füllstoff kann sich über die gesamte Länge des Gehäuseprofils und/oder der Dichtleiste erstrecken. Ebenso ist es möglich, dass einzelne Körper, die aus dem Füllstoff gebildet sind, mit Abstand zueinander in dem Hohlraum angeordnet sind.The filler arranged in a seal according to the invention can extend over the entire length of the housing profile and / or the sealing strip. It is also possible that individual bodies, which are formed from the filler, are arranged at a distance from each other in the cavity.

Die Menge des in den Hohlraum eingebrachten intumeszierenden Füllstoffes und/oder die Abstände zwischen Füllstoffkörpern wird bzw. werden vorteilhaft so bemessen, dass der Hohlraum im Brandfall von dem expandierendem Füllstoff vollständig oder nahezu vollständig ausgefüllt wird. Der intumeszierende Füllstoff wird vorteilhaft so ausgewählt, dass der Füllstoff sich im Brandfall in der Richtung oder den Richtungen ausdehnt, in der bzw. denen es für die Abdichtung gegen einen Rauchdurchtritt optimal ist.The amount of introduced into the cavity intumescent filler and / or the distances between filler bodies is or are advantageously sized so that the cavity is completely or almost completely filled in the event of fire of the expanding filler. The intumescent filler is advantageously selected so that the filler expands in the event of fire in the direction or directions in which it is optimal for sealing against passage of smoke.

Der Füllstoff kann oder die Füllstoffkörper können durch ein Klebeband oder ein oder mehrere Klebebandabschnitte gebildet werden. Ein derartiger Füllstoff kann intumeszierende und schalldämmende Eigenschaften haben.The filler or filler bodies may be formed by an adhesive tape or one or more pieces of adhesive tape become. Such a filler may have intumescent and soundproofing properties.

Vorzugsweise kann der intumeszierende Füllstoff drucklos aufschäumen. Durch den expandierten intumeszierenden Füllstoff kann im Brandfall der Mechanismus der Dichtung geschützt werden. Der Mechanismus kann insbesondere durch den drucklos expandierten Füllstoff vor Überhitzung geschützt werden. Der expandierte Füllstoff bewirkt eine thermische Trennung des Mechanismus und kann dadurch einen Durchbrand der Dichtung verhindern.Preferably, the intumescent filler can foam without pressure. Due to the expanded intumescent filler, the mechanism of the seal can be protected in case of fire. The mechanism can be protected against overheating, in particular by the pressure-less expanded filler. The expanded filler causes a thermal separation of the mechanism and can thereby prevent burnout of the seal.

Die in den Figuren dargestellte Dichtung ist in wesentlichen Teilen aus der europäischen Patentschrift EP 1 365 098 B 1 , Figur 1 und Figur 2 bekannt. Die Dichtung kann zum Beispiel in eine Nut an einem unteren Ende eines Türblattes T einer Drehflügeltür eingesetzt sein. Die Verwendung ist aber nicht auf Drehflügeltüren oder auf die Abdichtung der Bodenluft, d.h. dem Spalt zwischen Türblatt und Boden beschränkt. Die Dichtung kann auch an einem oberen oder unteren Ende eines Türflügels einer Schiebetür, einer Pendeltür oder einer anderen Tür angebracht sein.The seal shown in the figures is in essential parts from the European patent EP 1 365 098 B 1 . FIG. 1 and FIG. 2 known. The seal may for example be inserted into a groove at a lower end of a door leaf T of a swing door. However, the use is not limited to swing doors or to the sealing of the ground air, ie the gap between the door leaf and the floor. The seal may also be attached to an upper or lower end of a door panel of a sliding door, a swing door, or another door.

Die Dichtung weist ein Gehäuseprofil 1 auf, welches im wesentlichen die Form eines U hat. Die Dichtung umfasst ferner eine Dichtleiste 3, 4 und einen Mechanismus, welcher der Bewegung der Dichtleiste 3, 4 dient. Der Mechanismus umfasst einen Auslöser 2, der seitlich über das Gehäuseprofil 1 hinausragt. Der Auslöser 2 wird durch Druck betätigt. Durch eine Betätigung des Auslösers 2 wird die Dichtleiste 3, 4 aus einer Ruhestellung (Figur 2) in eine Dichtstellung bewegt. Sobald der Druck von dem Auslöser 2 genommen wird, kehrt die Dichtleiste 3, 4 in ihre Ruhestellung zurück. Diese Rückstellbewegung wird durch Federn, die Teil des Mechanismus sind, bewirkt.The seal has a housing profile 1, which has the shape of a U substantially. The seal further comprises a sealing strip 3, 4 and a mechanism which serves for the movement of the sealing strip 3, 4. The mechanism comprises a trigger 2, which projects laterally beyond the housing profile 1. The trigger 2 is actuated by pressure. By actuating the trigger 2, the sealing strip 3, 4 from a rest position ( FIG. 2 ) moved in a sealing position. As soon as the pressure is released from the trigger 2, the sealing strip 3, 4 returns to its rest position. This return movement is effected by springs which are part of the mechanism.

Die Dichtleiste 3, 4 umfasst ein Halteprofil 4 und ein Dichtungsprofil 3. Das Halteprofil 4 ist starr und ist mit dem Mechanismus verbunden. Das Dichtungsprofil 3 ist elastisch und an dem Halteprofil 4 angebracht. In der Dichtstellung wird das Dichtungsprofil 3 durch den Mechanismus gegen eine Anlagefläche B gedrückt, um einen Spalt gegen Schalldurchtritt, Rauchdurchtritt und Luftdurchtritt abzudichten.The sealing strip 3, 4 comprises a retaining profile 4 and a sealing profile 3. The retaining profile 4 is rigid and is connected to the mechanism. The sealing profile 3 is elastic and attached to the retaining profile 4. In the sealing position, the sealing profile 3 is pressed by the mechanism against a contact surface B, to seal a gap against sound transmission, smoke passage and air passage.

Das Halteprofil 4 ist im wesentlichen H-förmig. Es weist einen Steg 41, zwei in das Gehäuse gerichtete Schenkel 42 und zwei aus dem Gehäuseprofil 1 hinaus zeigende Schenkel 43 auf. An den Enden der in das Gehäuse gerichteten Schenkel 42 sind Verbindungsstrukturen 44 vorgesehen, in welche Verbindungsstrukturen 31 des Dichtungsprofils 3 eingreifen. Dadurch ist eine Verbindung zwischen dem Halteprofil 4 und dem Dichtungsprofil 3 dargestellt.The holding profile 4 is substantially H-shaped. It has a web 41, two legs 42 directed into the housing and two legs 43 pointing out of the housing profile 1. At the ends of the legs 42 directed into the housing connecting structures 44 are provided, in which connecting structures 31 of the sealing profile 3 engage. As a result, a connection between the retaining profile 4 and the sealing profile 3 is shown.

Zwischen dem Steg 41 und den in das Gehäuseprofil 1 weisenden Schenkeln 42 des Halteprofils 4 ist ein Hohlraum gebildet. Dieser Hohlraum ist in die Richtung zum Steg 11 des Gehäuseprofils 1 offen. Der zwischen den in das Gehäuseprofil 1 weisenden Schenkeln 42 des Halteprofils 4 gebildete Hohlraum ist mit einem weiteren Hohlraum zwischen dem Halteprofil 4 und dem Gehäuseprofil 1 verbunden.Between the web 41 and pointing into the housing profile 1 legs 42 of the holding section 4, a cavity is formed. This cavity is open in the direction of the web 11 of the housing profile 1. The cavity formed between the legs 42, which point in the housing profile 1, of the retaining profile 4 is connected to a further hollow space between the retaining profile 4 and the housing profile 1.

In dem Hohlraum zwischen den Enden der in das Gehäuseprofil 1 weisenden Schenkel 42 des Halteprofils 4 ist ein Körper aus einem intumeszierendem Füllstoff 5 angeordnet. Dieser Füllstoff 5 expandiert bei Hitze und hat dann eine Expansionsrichtung, die im wesentlichen in Richtung zum Steg 11 des Gehäuseprofils 1 gerichtet ist. Durch die Expansion des Füllstoffes 5 füllt sich der gesamte Hohlraum zwischen dem Steg 41 des Halteprofils 4 und dem Steg 11 des Gehäuseprofils 1. Die Expansion bewirkt dabei ein Absenken der Dichtungsleiste 2, 3, wodurch das Dichtungsprofil 3 gegen die Anlagefläche B gedrückt wird (Figur 4).In the cavity between the ends of pointing into the housing profile 1 leg 42 of the holding profile 4, a body of an intumescent filler 5 is arranged. This filler 5 expands in the heat and then has an expansion direction which is directed substantially in the direction of the web 11 of the housing profile 1 is. Due to the expansion of the filler 5, the entire cavity fills between the web 41 of the retaining profile 4 and the web 11 of the housing profile 1.
