Description
Die vorliegende Erfindung betrifft eine Dichtung für Türen zum Abdichten eines Luftspaltes zwischen einem Türflügel einerseits und einem Türrahmen, einem Fußboden, einer Zimmerdecke, einem Sturz o.ä. andererseits.The present invention relates to a seal for doors for sealing an air gap between a door leaf on the one hand and a door frame, a floor, a ceiling, a fall o.ä. on the other hand.
Aus dem Dokument
Das Gehäuse ist in eine sogenannte Außenschiene eingesetzt, wobei jedoch zwischen dem Gehäuse und der Außenschiene ein Abstand verbleibt. Durch diesen Abstand wird zwischen dem Gehäuse und dem Außenprofil ein Kanal gebildet, der sich von der Schließseite des Türflügels zur Öffnungsseite des Türflügels oder umgekehrt erstreckt. Dieser Kanal kann zu Lüftungszwecken in beiden Richtungen von Luft durchströmt werden, d.h. Luft kann sowohl von der Öffnungsseite zur Schließseite durch den Türflügel hindurchtreten wie auch umgekehrt.The housing is inserted into a so-called outer rail, but leaving a gap between the housing and the outer rail. By this distance, a channel is formed between the housing and the outer profile, which extends from the closing side of the door leaf to the opening side of the door leaf or vice versa. This channel can be traversed by air in both directions for ventilation purposes, i. Air can pass from the opening side to the closing side through the door leaf as well as vice versa.
In Gebäuden, insbesondere in Gebäuden mit lüftungstechnischen Anlagen sind häufig sogenannte Zulufträume und sogenannte Ablufträume eingerichtet. Den Zulufträumen wird über die lüftungstechnische Anlage Frischluft zugeführt, während aus den Ablufträumen Raumluft abgeführt wird. Zwischen diesen Räumen können weitere Räume liegen. Durch die lüftungstechnische Anlage wird die Luft aus den Zulufträumen über Luftspalten an Innentüren, ggf. über die weiteren Räume in die Ablufträume bewegt, um dann aus den Ablufträumen abgeführt zu werden. Den Luftspalten an den Innentüren kommt daher eine besondere Bedeutung in den Konzepten einer zentralen Be- und Entlüftung durch lüftungstechnische Anlagen zu. Luftspalten an Türen, die wegen des besseren Schallschutzes abgedichtet werden, müssen daher für eine funktionierende Lüftung für Luft hinreichend durchlässig sein. Schallschutz und Luftdurchlässigkeit sind aber zwei sich grundsätzlich widersprechende Anforderungen.In buildings, especially in buildings with ventilation systems often so-called Zulufträume and so-called exhaust air rooms are established. Fresh air is supplied to the supply air spaces via the ventilation system, while room air is discharged from the exhaust air spaces. There may be more rooms between these rooms. Through the ventilation system, the air from the Zulufträumen air gaps on the inner doors, possibly moved over the other rooms in the exhaust air chambers, and then to be discharged from the exhaust air. The air gaps to the Interior doors are therefore of particular importance in the concepts of central ventilation by ventilation systems. Air gaps on doors that are sealed for better sound insulation must therefore be sufficiently permeable for a functioning ventilation for air. Soundproofing and air permeability are two fundamentally contradictory requirements.
Hier setzt die vorliegende Erfindung an.This is where the present invention begins.
Der Erfindung liegt das Problem zugrunde, eine Dichtung für eine Tür, insbesondere eine Innentür vorzuschlagen, die einerseits einen Luftstrom zum Zwecke der Lüftung ermöglicht, andererseits einen unnötigen Luftstrom oder einen Schalldurchtritt durch die Tür minimiert oder verhindert.The invention is based on the problem to propose a seal for a door, in particular an inner door, on the one hand allows air flow for the purpose of ventilation, on the other hand minimizes or prevents unnecessary air flow or sound passage through the door.
Dieses Problem wird erfindungsgemäß dadurch gelöst, dass die Dichtung ein Dichtmittel umfasst, dass derart beweglich befestigt ist und/oder derart biegsam ist, dass es bei einem Druckgefälle von einer ersten Seite der Dichtung zu einer zweiten Seite der Dichtung eine Luftdurchtrittsöffnung zwischen der ersten Seite und der zweiten Seite der Dichtung freigibt.This problem is inventively solved in that the seal comprises a sealing means that is movably mounted and / or is so flexible that at a pressure gradient from a first side of the seal to a second side of the seal an air passage opening between the first side and the second side of the seal releases.
Für die Funktion einer zentralen Be- und Entlüftung durch lüftungstechnische Anlagen ist die Luftdurchlässigkeit in der Richtung ausreichend, in welche sich die Luft vom Zuluftraum zum Abluftraum bewegt. In die Gegenrichtung ist daher keine Luftdurchlässigkeit notwendig. Dadurch ist zumindest in den Zeiten, in denen keine Lüftung erfolgt, ein hinreichender Schallschutz erreicht, da in diesen Fällen der Luft- und Schalldurchtritt durch die Luftdurchtrittsöffnung verhindert ist.For the function of central ventilation by ventilation systems, the air permeability is sufficient in the direction in which the air moves from the supply air to the exhaust air space. In the opposite direction, therefore, no air permeability is necessary. As a result, sufficient soundproofing is achieved, at least in the periods in which no ventilation takes place, since in these cases the passage of air and sound through the air passage opening is prevented.
Vorzugsweise ist eine erfindungsgemäße Dichtung so gestaltet, dass das Dichtmittel die Luftdurchtrittsöffnung erst bei einem Mindestdruckgefälle von der ersten Seite zur zweiten Seite der Dichtung freigibt. Ein von dem Dichtmittel freigegebener Querschnitt der Luftdurchtrittsöffnung kann von dem Druckgefälle abhängen. Es kann sich dabei um eine Abhängigkeit gemäß dem Elastizitätsgesetz, insbesondere dem Hookeschen Gesetz handeln.Preferably, a seal according to the invention is designed so that the sealing means releases the air passage opening only at a minimum pressure gradient from the first side to the second side of the seal. A released from the sealant cross-section of the air passage opening may depend on the pressure gradient. This can be a dependency according to the elasticity law, in particular Hooke's law.
Eine erfindungsgemäße Dichtung kann insbesondere in Innentüren verwendet werden. Die Türen können Holztüren oder Metalltüren sein. Bei den Türen kann es sich um Schleusentüren, Türen zu Feuchträumen wie Bad, WC oder Küche, Türen zu Über- oder Unterdruckräumen oder zu Reinräumen handeln. Erfindungsgemäße Dichtungen können insbesondere in Türen von Häusern mit zentraler Be- und Entlüftung durch lüftungstechnische Anlagen, wie häufig in Passivhäusern oder in Gebäuden mit Nachtkühlung eingesetzt werden.A seal according to the invention can be used in particular in interior doors. The doors can be wooden doors or metal doors. The doors can be lock doors, doors to damp rooms such as bathrooms, toilets or kitchens, doors to over- or under-pressure rooms or to clean rooms. Inventive seals can be used in particular in doors of houses with central ventilation by ventilation systems, such as often in passive houses or in buildings with night cooling.
Eine erfindungsgemäße Dichtung kann ein erstes Haltemittel aufweisen, an welchem das Dichtmittel gelagert, geführt oder befestigt ist. Zum Freigeben der Luftdurchtrittsöffnung kann das Dichtmittel so an dem ersten Haltemittel angebracht sein, dass es gegenüber dem ersten Haltemittel linear bewegt und/oder gedreht wird. Es kann aber fest mit dem ersten Haltemittel verbunden sein. Dann sind vorzugsweise Teile des Dichtmittels zum Freigeben der Luftdurchtrittsöffnung bewegbar, insbesondere durch Verschieben und/oder durch Drehen oder Schwenken. Das erste Haltemittel kann ein Profil, eine Leiste oder ein Gehäuse sein. An dem ersten Haltemittel kann ein Kanal oder eine Fuge vorgesehen sein, in welchem bzw. welcher das Dichtungsmittel formschlüssig und/oder kraftschlüssig befestigt ist und/oder eingeklebt ist.A seal according to the invention may have a first holding means on which the sealing means is mounted, guided or fastened. To release the air passage opening, the sealing means may be attached to the first holding means such that it is linearly moved and / or rotated relative to the first holding means. But it can be firmly connected to the first holding means. Then preferably parts of the sealing means for releasing the air passage opening are movable, in particular by displacement and / or by turning or pivoting. The first holding means may be a profile, a bar or a housing. At the first holding means may be provided a channel or a joint in which or which the sealing means is positively and / or non-positively attached and / or glued.
Gemäß der Erfindung kann das Dichtmittel eine Dichtlippe oder - lamelle sein oder eine Dichtlippe oder -lamelle umfassen, die aus einem Elastomer hergestellt ist. Das Dichtmittel kann insbesondere aus Silikon hergestellt sein.According to the invention, the sealing means may be a sealing lip or lamella or comprise a sealing lip or lamella made of an elastomer. The sealant may in particular be made of silicone.
Es ist möglich, dass das Dichtmittel aus Materialien unterschiedlicher Härte hergestellt ist. Insbesondere dann kann das Dichtmittel Bereiche unterschiedlicher Elastizität aufweisen. Ferner ist es möglich, dass durch Formgebung, insbesondere durch Einschnürungen, unterschiedliche Materialstärken oder ähnliches die Elastizität oder die Beweglichkeit von Bereichen des Dichtmittel eingestellt ist, so dass Bereiche des Dichtmittels unterschiedlich auf ein Druckgefälle zum Öffnen der Luftdurchtrittsöffnung reagieren.It is possible that the sealant is made of materials of different hardness. In particular, then the sealant may have areas of different elasticity. Furthermore, it is possible that by shaping, in particular by constrictions, different material thicknesses or the like, the elasticity or the mobility of areas of the sealant is adjusted, so that areas of the sealant react differently to a pressure gradient for opening the air passage opening.
An dem Dichtmittel können Verbindungsstrukturen vorgesehen sein. Diese Verbindungsstrukturen können mit Verbindungsstrukturen an dem ersten Haltemittel zur Verbindung dieser beiden Teile der Dichtung zusammenwirken.Connection structures may be provided on the sealing means. These connection structures can cooperate with connection structures on the first holding means for connecting these two parts of the seal.
Bei einer erfindungsgemäßen Dichtung kann es sich um eine automatische Türdichtung handeln.A seal according to the invention may be an automatic door seal.
Die Dichtung kann ein Dichtungsgehäuse aufweisen. In diesem kann ein Mechanismus zum automatischen Absenken einer Dichtleiste beim Schließen einer mit der Dichtung ausgestatteten Tür untergebracht sein.The seal may have a seal housing. In this, a mechanism for automatically lowering a sealing strip when closing a door equipped with the seal can be accommodated.
Die Dichtleiste kann das Dichtmittel umfassen. Durch den Mechanismus wird dann das Dichtmittel angehoben oder abgesenkt. Im abgesenkten Zustand der Dichtung kann das Dichtmittel dann bei einem (hinreichenden) Druckgefälle von der ersten zur zweiten Seite die Luftdurchtrittöffnung freigeben.The sealing strip may comprise the sealant. The mechanism then raises or lowers the sealant. In the lowered state of the seal, the sealant can then release the air passage opening at a (sufficient) pressure gradient from the first to the second side.
Die Luftdurchtrittsöffnung kann ebenso außerhalb des Gehäuses vorgesehen sein. Dann ist vorteilhaft das Dichtmittel außerhalb des Dichtungsgehäuses angebracht. Die Luftdurchtrittsöffnung kann insbesondere durch einen Luftspalt zwischen dem Dichtungsgehäuse und einem Außengehäuse oder den Wänden einer Nut am unteren Ende eines Türblattes gebildet sein. Da automatische Dichtungen auch auf einer Öffnungsseite oder einer Schließseite eines Türflügels angebracht sein können, kann die Luftdurchtrittsöffnung auch durch einen Luftspalt zwischen dem Gehäuse und der Öffnungsseite oder der Schließseite der Tür gebildet sein.The air passage opening may also be provided outside the housing. Then, advantageously, the sealant is mounted outside the seal housing. The air passage opening may in particular be formed by an air gap between the seal housing and an outer housing or the walls of a groove at the lower end of a door leaf. Since automatic seals may also be mounted on an opening side or a closing side of a door leaf, the air passage opening may also be formed by an air gap between the housing and the opening side or the closing side of the door.
Gemäß der Erfindung kann das Dichtmittel an dem Gehäuse angebracht sein. Dann kann das Gehäuse das erste Haltemittel bilden.According to the invention, the sealing means may be attached to the housing. Then, the housing can form the first holding means.
Alternativ kann das erste Haltemittel vom Gehäuse verschieden sein. Das erste Haltemittel könnte dann an dem Gehäuse befestigt sein. Ebenso ist es möglich, dass das mit Abstand zu dem ersten Haltemittel befestigt ist. Die Luftdurchtrittsöffnung kann dann zwischen dem Gehäuse und dem Haltemittel vorgesehen sein. Im gesperrten Zustand der Luftdurchtrittsöffnung kann das Dichtmittel an dem Gehäuse anliegen.Alternatively, the first holding means may be different from the housing. The first retaining means could then be attached to the housing. It is also possible that this is fixed at a distance from the first holding means. The air passage opening may then be provided between the housing and the holding means. In the locked state of the air passage opening, the sealant may rest against the housing.
Eine erfindungsgemäße Dichtung kann wenigstens ein Befestigungsmittel umfassen, dass einerseits mit dem Gehäuse lösbar verbunden ist und andererseits zur Befestigung der Dichtung an einem Türflügel geeignet und eingerichtet ist. Es kann sich dabei um einen Befestigungswinkel handeln. Das Befestigungsmittel kann insbesondere vorgesehen sein, um das Gehäuse einer erfindungsgemäßen automatischen Dichtung in einer Nut einer Tür oder an der Öffnungsseite oder Schließseite einer Tür anzubringen. Vorzugsweise kann bei einer erfindungsgemäßen Dichtung ein Distanzelement vorgesehen sein, welches ein Mindestmaß oder ein genaues Maß für einen Querschnitt der Luftdurchtrittsöffnung festlegt. Das Distanzelement kann Teil des Befestigungsmittels sein. Durch das Distanzelement kann zum Beispiel die Position des Gehäuses einer automatischen Dichtung in der Nut einer Tür oder relativ zur Öffnungsseite oder Schließseite einer Tür festgelegt sein.A seal according to the invention may comprise at least one fastening means, which on the one hand is detachably connected to the housing and on the other hand is suitable and arranged for fastening the seal to a door leaf. It may be a mounting bracket. The fastening means may in particular be provided for mounting the housing of an automatic seal according to the invention in a groove of a door or on the opening side or closing side of a door. Preferably, in a seal according to the invention, a spacer element may be provided which defines a minimum dimension or an exact dimension for a cross section of the air passage opening. The spacer may be part of the fastener. By the spacer element, for example, the position of the housing of an automatic seal in the groove of a door or relative to the opening side or closing side of a door can be defined.
Eine erfindungsgemäße Dichtung kann eine Auflaufdichtung sein. Das Dichtungsmittel dichtet dann im geschlossenen Zustand der Tür gegenüber einer Schwelle ab. Ebenso ist es möglich, dass die Dichtung eine Anschlagdichtung ist.A seal according to the invention may be a casserole seal. The sealant then seals in the closed state of the door from a threshold. It is also possible that the seal is a stop seal.
In einer besonderen Ausführung der Dichtung kann das Dichtmittel eine in einer Richtung durchlässige Membran sein.In a particular embodiment of the seal, the sealant may be a permeable membrane in one direction.
Eine erfindungsgemäße Dichtung kann eine Absorberkammer oder einen Helmholtzresonator aufweisen. Dieser kann insbesondere so zu dem Gehäuse einer automatischen Dichtung positioniert sein, dass er bei einer in einer Nut am unteren Ende des Türflügels montierten Dichtung oberhalb des Gehäuses der Dichtung angeordnet ist. An dieser Stelle oder auch an anderen Stellen der Dichtung kann auch ein Absorbermaterial angeordnet sein, welches Schall absorbiert.A seal according to the invention may have an absorber chamber or a Helmholtz resonator. In particular, it may be positioned relative to the housing of an automatic seal such that it is disposed above the housing of the seal in a seal mounted in a groove at the lower end of the door leaf. At this point or at other locations of the seal may also be arranged an absorber material which absorbs sound.
Ferner ist es möglich, dass die Dichtung mit intumeszierendem Material ausgestattet ist, mit dem in einem Brandfall die Luftdurchtrittsöffnung oder andere Öffnungen rauchdicht und branddicht verschlossen werden.Further, it is possible that the seal is equipped with intumescent material with which the air passage opening or other openings are sealed smoke-tight and fire-proof in case of fire.
Eine erfindungsgemäße Dichtung kann auch eine ein- und ausschaltbare Dichtung sein, wie sie zum Beispiel in der Druckschrift
