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 EP 1 936 097 A1 ist eine Dichtung bekannt, mit welcher ein Luftspalt zwischen einem unteren Ende eines Türflügels und einem Fußboden abgedichtet werden kann. Die Dichtung weist ein Gehäuse auf, welches in dem Dokument als Führungsprofil bezeichnet ist. In diesem Gehäuse ist eine bewegliche Dichtleiste angeordnet, wie es von automatischen Dichtungen bekannt ist. Die Dichtleiste wird beim Schließen des mit der Dichtung ausgestatteten Türflügels abgesenkt und beim Öffnen der Tür angehoben.From the document EP 1 936 097 A1 For example, a seal is known with which an air gap between a lower end of a door leaf and a floor can be sealed. The seal has a housing, which is referred to in the document as a guide profile. In this housing, a movable sealing strip is arranged, as it is known from automatic seals. The sealing strip is lowered when closing the door equipped with the seal and raised when opening the door.

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 spaces, and then 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 durch eine Dichtung mit den Merkmalen des Anspruchs 1 gelöst.This problem is solved by a seal with the features of claim 1.

Bei einer erfindungsgemäßen Dichtung handelt es sich um eine automatische Türdichtung. Die Dichtung weist ein Dichtungsgehäuse auf. In diesem ist ein Mechanismus zum automatischen Absenken einer Dichtleiste beim Schließen einer mit der Dichtung ausgestatteten Tür untergebracht. Die Dichtung weist eine Luftdurchtrittsöffnung zwischen einer ersten Seite und einer zweiten Seite der Dichtung auf. Die Luftdurchtrittsöffnung ist außerhalb des Gehäuses vorgesehen.A seal according to the invention is an automatic door seal. The seal has a seal housing. In this a mechanism for automatically lowering a sealing strip is housed when closing a door equipped with the seal. The seal has an air passage opening between a first side and a second side of the seal. The air passage opening is provided outside the housing.

Zusätzlich umfasst eine erfindungsgemäße Dichtung nach Anspruch 1 ein Dichtmittel, das derart beweglich befestigt ist und/oder derart biegsam ist, dass es bei einem Druckgefälle von der ersten Seite der Dichtung zu der zweiten Seite der Dichtung die Luftdurchtrittsöffnung freigibt. Das Dichtmittel ist außerhalb des Dichtungsgehäuses angebracht.In addition, a seal according to the invention according to claim 1 comprises a sealing means which is movably mounted and / or is so flexible that it at a pressure gradient from the first side of the seal to the second side of the seal, the air passage opening releases. The sealant is mounted outside the seal housing.

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 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.

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 may be lock doors, doors closed Humid rooms such as bathrooms, toilets or kitchens, doors to over- or under-pressure rooms or to cleanrooms act. 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.

Zunächst wird auf die Figuren 1 bis 7 Bezug genommen, die Varianten einer in einer Nut in einem Türflügel angebrachten automatischen Dichtung mit einer Dichtlippe als Dichtmittel zeigen. Zunächst werden die Gemeinsamkeiten der Dichtungen beschrieben, bevor dann die individuellen Merkmale der Dichtungen beschrieben werden.
Merkmale die nur für eine Variante beschrieben werden, können auch bei anderen Varianten verwendet werden, auch wenn das nicht eigens dargestellt oder beschrieben ist. Das gilt auch für alle weiteren Dichtungen, die in den Figuren dargestellt sind.
First, on the FIGS. 1 to 7 Referring to show the variants of a mounted in a groove in a door leaf automatic seal with a sealing lip as a sealant. First, the commonality of the seals will be described before describing the individual characteristics of the seals.
Features that are only described for one variant can also be used for other variants, even if this is not specifically illustrated or described. This also applies to all other seals that are shown in the figures.

Die Varianten der erfindungsgemäßen automatischen Dichtungen weisen ein Gehäuse 3 auf, das mittels eines Befestigungswinkels 2 und Befestigungselementen 1, im Beispiel handelt es sich um Schrauben, in einer Nut am unteren Ende eines Türflügels T befestigt ist. Das Gehäuse ist im Querschnitt im Wesentlichen U-förmig und weist zwei Schenkel und einen die Schenkel verbindenden Steg auf.The variants of the automatic seals according to the invention have a housing 3, which is fastened in a groove at the lower end of a door leaf T by means of a fastening angle 2 and fastening elements 1, in the example screws. The housing is in cross-section substantially U-shaped and has two legs and a web connecting the legs.

Die Befestigung des Gehäuses erfolgt so, dass zwischen einem Nutgrund und dem Steg des Gehäuses und Seitenwänden der Nut und den Schenkeln des Gehäuses 3 eine Luftdurchtrittsöffnung L verbleibt. Durch diese Luftdurchtrittsöffnung ist eine gerichtete Luftströmung möglich. Die Richtung dieser Strömung ist in der Fig. 1 und den Fig. 5 bis 7 durch Pfeile angegeben.The attachment of the housing is such that between an end of the groove and the web of the housing and side walls of the groove and the legs of the housing 3, an air passage opening L remains. Through this air passage, a directed air flow is possible. The direction of this flow is in the Fig. 1 and the Fig. 5 to 7 indicated by arrows.

In dem Gehäuse 3 ist ein Mechanismus vorgesehen, der an dem Gehäuse 3 befestigt ist und an welchem eine Dichtleiste 4, 5 befestigt ist. Die Dichtleiste 4, 5 umfasst ein Halteprofil 4 und ein Dichtprofil 5 in bekannter Ausführung. Von diesem Mechanismus ist lediglich ein Auslöser 6 dargestellt, welcher bei einem Druck eine Abwärtsbewegung der Dichtleiste 4, 5 auslöst, durch welche die Dichtleiste 4, 5 nach unten gegen einen Fußboden B oder ähnliches gedrückt wird, um einen Luftspalt zwischen dem unteren Ende der Tür T und dem Fußboden B abzudichten. Der Mechanismus ist in verschiedenen Bauarten aus dem Stand der Technik bekannt. Der Aufbau der Dichtung innerhalb des Gehäuses 3 kann aus dem Stand der Technik bekannt sein.In the housing 3, a mechanism is provided, which is fixed to the housing 3 and to which a sealing strip 4, 5 is attached. The sealing strip 4, 5 comprises a retaining profile 4 and a sealing profile 5 in a known design. Of this mechanism, only a trigger 6 is shown, which at a pressure, a downward movement of the sealing strip 4, 5 triggers, through which the sealing strip 4, 5 is pressed down against a floor B or the like to an air gap between the lower end of the door T and the floor B to seal. The mechanism is known in various designs from the prior art. The construction of the seal within the housing 3 may be known in the art.

Die zwischen dem Gehäuse 3 und dem Nutgrund bzw. der Nutwand ausgebildete Luftdurchtrittsöffnung L ist, je nach Druckverhältnissen an der Tür T durch ein Dichtmittel 7 abgedichtet. Ein wesentlicher Unterschied zwischen den in den Fig. 1 bis 7 dargestellten Varianten liegt in der Gestaltung des Dichtmittels 7 und in der Anbringung des Dichtmittels 7.The formed between the housing 3 and the groove bottom or the groove wall air passage opening L is sealed depending on the pressure conditions on the door T by a sealing means 7. A major difference between those in the Fig. 1 to 7 illustrated variants lies in the design of the sealant 7 and in the attachment of the sealant. 7

Die Dichtmittel der in den Fig. 1 bis 7 dargestellten Varianten einer erfindungsgemäßen Dichtung sind aus einem Elastomer hergestellte Dichtlippen.The sealants in the Fig. 1 to 7 illustrated variants of a seal according to the invention are made of an elastomer sealing lips.

Bei der in der Fig. 1 dargestellten Variante sind am unteren Ende der Schenkel des Gehäuses 3 auf der Außenseite des Gehäuses 3 Kanäle 31 vorgesehen. Diese Kanäle sind am Gehäuse 3 symmetrisch ausgebildet, um die Lüftungsrichtung zum Montagezeitpunkt der Dichtung an der Tür festlegen zu können. In einem dieser Kanäle 31, nämlich in dem in der Fig. 1 links dargestellten Kanal 31 ist eine Wulst 71 des Dichtmittels 7 eingezogen, wodurch das Dichtmittel 7 in dem Kanal 31 im Wesentlichen durch Formschluss gehalten wird. In einem entspannten Zustand des elastomeren Dichtmittels liegt ein freies Ende des Dichtmittels an der Unterseite der Tür T an. Bei einem hinreichenden Druckunterschied zwischen einer ersten Seite der Dichtung, die einer ersten Seite der Tür T entspricht, und einer zweiten Seite der Dichtung, die einer zweiten Seite der Tür T entspricht, hebt das Dichtmittel 7 in eine Öffnungsrichtung des Dichtmittels 7 von der Unterseite der Tür 7 ab und gibt damit die Luftdurchtrittsöffnung L für eine Luftströmung um das Gehäuse 3 der Dichtung frei. Ist der Druckunterschied umgekehrt, wird das Dichtmittel 7 entgegen seiner Öffnungsrichtung gegen die Unterseite der Tür T gedrückt, wodurch die Luftdurchtrittsöffnung für eine Luftströmung versperrt ist.When in the Fig. 1 illustrated variant 3 channels 31 are provided at the lower end of the legs of the housing 3 on the outside of the housing. These channels are formed symmetrically on the housing 3 in order to be able to determine the direction of ventilation at the time of installation of the seal on the door. In one of these channels 31, namely in the in the Fig. 1 Channel 31 shown on the left is retracted a bead 71 of the sealant 7, whereby the sealant 7 is held in the channel 31 substantially by positive engagement. In a relaxed state of the elastomeric sealant is a free end of the sealant on the underside of the door T on. At a sufficient pressure difference between a first side of the gasket corresponding to a first side of the door T and a second side of the gasket corresponding to a second side of the door T, the sealing agent 7 lifts in an opening direction of the sealant 7 from the bottom of the door Door 7 and thus releases the air passage opening L for an air flow around the housing 3 of the seal. If the pressure difference is reversed, the sealing means 7 is pressed counter to its opening direction against the underside of the door T, whereby the air passage opening is blocked for an air flow.

Bei den in den Figuren 2 und 3 dargestellten Varianten sind die Dichtmittel an einem oberen Ende des Schenkels im Bereich der Kante zwischen dem Schenkel und dem Steg des Gehäuses 3 am Gehäuse 3 befestigt. Bei der Variante nach Fig. 2 ist das Dichtmittel 7 in eine von zwei Fugen eingeklebt, die am Gehäuse 3 symmetrisch ausgebildet sind, um die Lüftungsrichtung zum Montagezeitpunkt der Dichtung an der Tür festlegen zu können. Bei der Variante nach Fig. 3 ist eine Wulst 71 in einen von zwei Kanälen 31 eingezogen und durch Formschluss befestigt. Diese Kanäle sind am Gehäuse 3 symmetrisch ausgebildet, um die Lüftungsrichtung zum Montagezeitpunkt der Dichtung an der Tür festlegen zu können. Bei beiden Varianten liegt ein freies Ende des Dichtmittels an einer Nutwand an. Durch einen Druckunterschied können bei den Varianten nach den Fig. 2 und 3 die Dichtmittel in Richtung der Schenkel des Gehäuses geschwenkt werden, um die Luftdurchtrittsöffnung L für einen Luftstrom freizugeben.In the in the FIGS. 2 and 3 variants shown, the sealing means are attached to an upper end of the leg in the region of the edge between the leg and the web of the housing 3 on the housing 3. In the variant after Fig. 2 the sealant 7 is glued into one of two joints, which are formed symmetrically on the housing 3 in order to determine the direction of ventilation at the time of installation of the seal on the door can. In the variant after Fig. 3 a bead 71 is drawn into one of two channels 31 and fixed by positive locking. These channels are formed symmetrically on the housing 3 in order to be able to determine the direction of ventilation at the time of installation of the seal on the door. In both variants lies a free end of the sealant on a groove wall. By a pressure difference can in the variants after the FIGS. 2 and 3 the sealing means are pivoted in the direction of the legs of the housing to release the air passage opening L for a flow of air.

Die in der Fig. 3 dargestellte Variante unterscheidet sich von der Fig. 1 dargestellten Variante im Wesentlichen durch das Dichtungsprofil 4 der Dichtleiste 4, 5. Dieses hat bei der Variante nach Fig. 4 Flügel, die an der Innenseite des Gehäuses 3 anliegen und damit einen Luftzug oder Schalldurchtritt durch das Gehäuse 3 unterbinden oder zumindest erschweren.The in the Fig. 3 variant shown differs from the Fig. 1 illustrated variant essentially by the sealing profile 4 of the sealing strip 4, 5. This has in the variant after Fig. 4 Wing, which rest against the inside of the housing 3 and thus prevent or at least complicate a draft or sound passage through the housing 3.

Bei den in den Figuren 5 bis 7 dargestellten Varianten ist das Dichtmittel 7 nicht an dem Gehäuse 3 der Dichtungen angebracht. Vielmehr weisen bei diesen Varianten die Dichtungen ein vom Gehäuse 3 getrenntes erstes Haltemittel 9 auf, welches in der Nut des Türflügels T befestigt ist. Diese erste Haltemittel 9 weisen einen Kanal auf, in welche die Dichtmittel 7 eingezogen und formschlüssig befestigt sind. Freie Enden der Dichtmittel 7 liegen bei gesperrter Luftdurchtrittsöffnung L an dem Gehäuse 3 an.In the in the FIGS. 5 to 7 illustrated variants, the sealant 7 is not attached to the housing 3 of the seals. Rather, in these variants, the seals on a separate housing 3 from the first holding means 9, which is fixed in the groove of the door leaf T. These first holding means 9 have a channel into which the sealing means 7 are drawn and fixed in a form-fitting manner. Free ends of the sealing means 7 are in blocked air passage opening L to the housing 3.

Bei den Varianten gemäß den Figuren 5 und 6 sind im Nutgrund Schallabsorber 8 vorgesehen, die insbesondere bei durch das Dichtmittel 7 freigegebener Luftdurchtrittsöffnung L einen Schalldurchtritt durch die Luftdurchtrittsöffnung unterbinden oder zumindest erschweren. Bei der Variante gemäß der Fig. 5 füllt der Absorber den gesamten Nutgrund aus und das erste Haltemittel 9 ist an dem Absorber 8 befestigt. Bei der Variante gemäß Fig. 6 ist das erste Haltemittel 9 am Nutgrund befestigt und der nicht vom ersten Haltemittel 9 abgedeckte Bereich des Nutgrundes ist mit dem Absorber 8 bedeckt. Es ist bei den Varianten gemäß den Figuren 5 und 6 möglich, dass der Schallabsorber 8 intumeszierende Eigenschaften hat.At variants according to FIGS. 5 and 6 Sound absorbers 8 are provided in the groove base, which prevent or at least complicate a passage of sound through the air passage opening in particular when released through the sealing means 7 air passage opening L. In the variant according to the Fig. 5 the absorber fills the entire groove bottom and the first holding means 9 is attached to the absorber 8. In the variant according to Fig. 6 the first holding means 9 is fastened to the groove base and the region of the groove base not covered by the first holding means 9 is covered with the absorber 8. It is with variants according to Figures 5 and 6 possible that the sound absorber 8 has intumescent properties.

Die erfindungsgemäße Dichtungsvariante gemäß Fig. 7 ist anders als die bisher diskutierten Varianten nicht in der Nut einer Holztür sondern in der Nut einer Metalltür vorgesehen. In der dargestellten Variante sind zwei erste Haltemittel 9 im Nutgrund vorgesehen, so dass der Anbringungsort und die Durchlassrichtung des Dichtmittels 7 geändert bzw. ausgewählt werden kann.The seal variant according to the invention Fig. 7 is unlike the previously discussed variants not in the groove of a wooden door but provided in the groove of a metal door. In the illustrated variant, two first holding means 9 are provided in the groove base, so that the mounting location and the passage direction of the sealant 7 can be changed or selected.

Die Figuren 8 bis 13 betreffen die Befestigung des Gehäuses 3 der Dichtungen der in den Figuren 1 bis 7 dargestellten Varianten in der Nut einer Tür mit einem Befestigungswinkel 2. Bei der Befestigung der Dichtung in einer Nut einer Tür muss sichergestellt werden, dass der Querschnitt der Luftdurchtrittsöffnung so groß ist, dass eine hinreichende Luftströmung möglich ist, ohne dass ein Maximalwert für eine Strömungsgeschwindigkeit überschritten wird und Zugerscheinungen auftreten. Dieses Mindestmaß für den Querschnitt kann konstruktiv durch die Gestaltung des Befestigungswinkels 2 festgelegt werden.The FIGS. 8 to 13 relate to the attachment of the housing 3 of the seals in the FIGS. 1 to 7 When mounting the seal in a groove of a door must be ensured that the cross section of the air passage opening is so large that a sufficient air flow is possible without exceeding a maximum value for a flow velocity and drafts will occur. This minimum dimension for the cross section can be structurally determined by the design of the mounting bracket 2.

Die Figuren 8 und 9 zeigen grundsätzlich die Möglichkeit ein Gehäuse 3 einer erfindungsgemäßen Dichtung in einer Nut mit einem Befestigungswinkel 2 und einer Schraube 1 zu befestigen, wie sie auch schon aus dem Dokument DE 203 00 265 U1 bekannt ist. Der Befestigungswinkel 2 weist einen ersten Schenkel und einen zweiten Schenkel auf. Der erste Schenkel ist in das Gehäuse 3 eingesteckt. Der zweite Schenkel weist ein Langloch auf, durch welche die Schraube 1 hindurch und in den Türflügel T eingeschraubt ist.The FIGS. 8 and 9 show in principle the possibility to attach a housing 3 of a seal according to the invention in a groove with a mounting bracket 2 and a screw 1, as they already from the document DE 203 00 265 U1 is known. The mounting bracket 2 has a first leg and a second leg. The first leg is inserted into the housing 3. The second leg has a slot through which the screw 1 is screwed through and into the door leaf T.

Die Fig. 10 zeigt eine Variante des Befestigungswinkels mit zwei parallelen Langlöchern. Diese haben den Vorteil, dass ein Verdrehen des Gehäuses 3 bzw. der Befestigungswinkel 2 bei einer möglicherweise unsachgemäßen Krafteinwirkung auf die Dichtung erschwert oder verhindert wird. Außerdem ist diese Variante des Befestigungswinkels so gestaltet, dass der zweite Schenkel breiter als die Nut ist und sich in der Ebene des zweiten Schenkels nach unten, in Richtung des unteren Endes des Türflügels T weisende Laschen anschließen. Durch den breiteren ersten Schenkel und die Laschen wird die Luftdurchtrittsöffnung seitlich abgedeckt.The Fig. 10 shows a variant of the mounting bracket with two parallel slots. These have the advantage of being twisted of the housing 3 or the mounting bracket 2 is difficult or prevented in a possibly improper force on the seal. In addition, this variant of the mounting bracket is designed so that the second leg is wider than the groove and connect in the plane of the second leg down, towards the lower end of the door T-facing tabs. Due to the wider first leg and the tabs, the air passage opening is covered laterally.

Die Figuren 11 bis 13 zeigen Varianten von Befestigungswinkeln 2 mit Distanzelementen 21, die einen Mindestabstand des Gehäuses vom Nutgrund sicherstellen. Befestigungswinkel dieser Art sind grundsätzlich bereits in der Gebrauchsmuseranmeldung DE 20 2013 105 687 beschrieben. Das Distanzelement 21 der Variante aus Fig. 13 oder ein weiteres Distanzelement sorgt nicht nur für einen Mindestabstand zum Nutgrund sondern auch für einen definierten seitlichen Mindestabstand des Gehäuses zu den Nutwänden. Dadurch kann ein Mindestquerschnitt der Luftdurchtrittöffnung L sicher gestellt werden.The FIGS. 11 to 13 show variants of mounting brackets 2 with spacers 21, which ensure a minimum distance of the housing from the groove bottom. Mounting brackets of this type are already in the utility license application DE 20 2013 105 687 described. The spacer element 21 of the variant Fig. 13 or a further spacer element not only ensures a minimum distance to the groove bottom but also for a defined lateral minimum distance of the housing to the groove walls. Thereby, a minimum cross section of the air passage opening L can be ensured.

Die in den Figuren 14 bis 18 dargestellten Varianten von erfindungsgemäßen automatischen Dichtungen sind für eine Montage an einer Schließseite eines Türflügels vorgesehen. Die Gehäuse, die Mechanismen in den Gehäusen und die Dichtleisten der Dichtungen entsprechen grundsätzlich den Dichtungen aus der Fig. 1 bzw. 5 bis 7.The in the FIGS. 14 to 18 illustrated variants of automatic seals according to the invention are provided for mounting on a closing side of a door leaf. The housings, the mechanisms in the housings and the sealing strips of the gaskets basically correspond to the gaskets of the Fig. 1 or 5 to 7.

Die Dichtung gemäß Fig. 14 bis 16 unterscheidet sich von der Dichtung gemäß Fig. 1 durch den verwendeten Befestigungswinkel 2 und das verwendete Dichtmittel 7. Der Befestigungswinkel 2 ist so gestaltet, dass das Gehäuse 3 der Dichtung in einem durch Distanzelemente 21 festgelegten Abstand zur Schließseite des Türflügels T befestigt ist. An einem ersten Schenkel des Befestigungswinkels sind als Distanzelemente 21 zwei Vorsprünge vorgesehen, die seitlich in das Gehäuse eingesteckt sind und dadurch nicht nur den Abstand des Gehäuses 3 zum Türflügel T festlegen sondern auch eine formschlüssige Verbindung zwischen dem Gehäuse 3 und dem Befestigungswinkel 2 schaffen. Ein zweiter Schenkel des Befestigungswinkels weist zwei Schraublöcher auf, durch welche Schrauben 1 zur Befestigung am Türflügel T hindurchgeführt sind. Durch den Abstand des Gehäuses 3 vom Türflügel T wird die Luftdurchtrittsöffnung L geschaffen.The seal according to Fig. 14 to 16 differs from the seal according to Fig. 1 by the used mounting bracket 2 and the sealant used 7. The mounting bracket 2 is designed so that the housing 3 of the seal in a distance defined by spacers 21 to the closing side of the Door leaf T is attached. On a first leg of the mounting bracket 21 are provided as spacers two projections which are laterally inserted into the housing and thereby not only set the distance of the housing 3 to the door T but also create a positive connection between the housing 3 and the mounting bracket 2. A second leg of the mounting bracket has two screw holes through which screws 1 are passed for attachment to the door T. Due to the distance of the housing 3 from the door T, the air passage opening L is created.

In dem ersten Schenkel ist zwischen den Vorsprüngen eine Ausnehmung vorgesehen, durch die ein Auslöser 6 der Dichtung hindurch geführt ist.In the first leg, a recess is provided between the projections through which a trigger 6 of the seal is guided.

In dem Kanal 31 am unteren Ende des dem Türflügel T zugewandten Schenkels des Gehäuses 3 ist ein Dichtmittel 7 eingezogen, welches am Türflügel T anliegt, wenn die Luftdurchtrittsöffnung L für einen Luftdurchtritt gesperrt ist.In the channel 31 at the lower end of the door leaf T facing leg of the housing 3, a sealing means 7 is retracted, which abuts the door T, when the air passage opening L is blocked for passage of air.

In der Fig. 16 ist neben der Dichtung und dem Türflügel ein Teil des Türrahmens R und eine Falzdichtung F dargestellt.In the Fig. 16 a part of the door frame R and a rebate seal F is shown next to the seal and the door leaf.

Die in den Figuren 17 und 18 dargestellten Varianten unterscheiden sich von der Dichtung gemäß den Fig. 14 bis 16 im Wesentlichen dadurch, dass das Dichtmittel 7 nicht an dem Gehäuse 3 befestigt ist sondern an einem ersten Haltemittel 9, welches an der Schließseite des Türflügels T befestigt ist. Das Dichtmittel 7 liegt bei der Variante gemäß Fig. 17 an dem der Schließseite des Türflügels T zugewandten Schenkel des Gehäuses an, wenn die Luftdurchtrittsöffnung L gesperrt ist. Bei der Variante gemäß Fig. 18 liegt das Dichtmittel dagegen an dem Steg des Gehäuses 3 an. Das Haltemittel 9 ist bei beiden Varianten so gestaltet, dass es den Spalt zwischen dem Gehäuse 3 der Dichtung und dem Türblatt abdeckt, ohne ihn zu verschließen.The in the FIGS. 17 and 18 Variants shown differ from the seal according to the Fig. 14 to 16 essentially in that the sealing means 7 is not fastened to the housing 3 but to a first holding means 9, which is fastened to the closing side of the door leaf T. The sealant 7 is in the variant according to Fig. 17 on which the closing side of the door leaf T facing legs of the housing, when the air passage opening L is locked. In the variant according to Fig. 18 on the other hand, the sealing means abuts against the web of the housing 3. The holding means 9 is at both variants designed so that it covers the gap between the housing 3 of the seal and the door leaf, without closing it.

Die in den Fig. 19 und 20 dargestellte Anschlagdichtung ist wie die Dichtungen gemäß den Fig. 1 bis 13 in Nuten an unteren Enden von Türflügeln T montiert. Sie weist ein erstes Haltemittel 9 auf, welches mit Schrauben 1 im Nutgrund befestigt ist. Das Haltemittel 9 hat einen Kanal 91 in welchem das Dichtmittel 7 eingezogen ist. Das Dichtmittel 7 ragt aus der Nut heraus. Eine Luftdurchtrittsöffnung wird durch die Unterseite des Türflügels T und einer Schwelle S begrenzt. Im gesperrten Fall (in Fig. 19 dargestellt) schlägt das Dichtmittel 7 an der Schwelle S an während im Fall der freigegebenen Luftdurchtrittsöffnung (Fig. 20) das Dichtmittel 7 durch den Druckunterschied auf den verschiedenen Seiten der Dichtung von der Schwelle abgehoben ist.The in the FIGS. 19 and 20 Shock seal shown is like the seals according to the Fig. 1 to 13 mounted in grooves at lower ends of door leaves T. It has a first holding means 9, which is fastened with screws 1 in the groove base. The holding means 9 has a channel 91 in which the sealing means 7 is retracted. The sealant 7 protrudes out of the groove. An air passage opening is bounded by the underside of the door leaf T and a threshold S. In the locked case (in Fig. 19 shown) proposes the sealant 7 at the threshold S while in the case of the released air passage opening ( Fig. 20 ) the sealant 7 is lifted from the sill by the pressure difference on the different sides of the seal.

In den Fig. 21a bis 21e sind verschiedene Varianten des Dichtmittels 7 in Seitenansichten dargestellt, die sowohl bei der Anschlagdichtung nach Fig. 19 und 20, als auch bei den Auflaufdichtungen gemäß den Fig. 22 und 23 verwendet werden können. Im einzelnen zeigt
Teilfigur a) ein Dichtmittel 7 aus einem homogenen Material,
Teilfigur b) ein nach unten verjüngtes Dichtmittel 7, dessen unteres Ende eine höhere Flexibilität hat als das obere, um so einen Luftdurchlass leichter zu machen,
Teilfigur c) ein Dichtmittel 7 mit einseitigen Sollknickstellen, um eine Bewegung in die eine Richtung zu erleichtern und in die andere Richtung zu erschweren
Teilfigur d) ein Dichtmittel 7 aus einer Kombination von einem harten Material (oben) und einem weichen Material (unten) und
Teilfigur e) ein Dichtmittel 7 mit mehreren Sollknickstellen.
In the Fig. 21a to 21e are different variants of the sealant 7 shown in side views, which in both the stopper seal after FIGS. 19 and 20 , as well as at the casserole seals according to FIGS. 22 and 23 can be used. In detail shows
Part a) a sealant 7 made of a homogeneous material,
Sub-figure b) a downwardly tapered sealing means 7, the lower end has a higher flexibility than the upper, so as to make an air passage easier,
Sub-figure c) a sealant 7 with one-sided Sollknickstellen to facilitate movement in one direction and to complicate in the other direction
Part d) a sealant 7 from a combination of a hard material (above) and a soft material (below) and
Part figure e) a sealant 7 with several predetermined bending points.

Die Auflaufdichtung gemäß Fig. 22 weist ein erstes Haltemittel 9 auf, dass über Befestigungswinkel 2 mit einem Langloch und mit einer durch das Langloch geführten Schraube 1 in der Nut eines Türflügels befestigt ist. Das in einen Kanal 91 des ersten Haltemittels 9 eingezogene Dichtmittel 7 ragt unten aus der Nut heraus. Das Maß, um welches das Dichtmittel 7 aus der Nut herausragt, kann durch die Positionierung des ersten Haltemittels 9 mittels des Befestigungswinkels 2 festgelegt werden. Die Auflaufdichtung gemäß Fig. 22 weist ein im Nutgrund angebrachten Schallabsorber 8 auf, welcher einen Schallschutz verbessert.The casserole according to Fig. 22 has a first holding means 9 that is attached via mounting bracket 2 with a slot and with a run through the slot screw 1 in the groove of a door leaf. The retracted in a channel 91 of the first holding means 9 sealing means 7 protrudes down out of the groove. The extent to which the sealing means 7 protrudes from the groove can be determined by the positioning of the first holding means 9 by means of the mounting bracket 2. The casserole according to Fig. 22 has a sound absorber 8 mounted in the groove base, which improves sound insulation.

Bei der Auflaufdichtung gemäß Fig. 23 ist dagegen ein erstes Haltemittel 9 mittels Schrauben 1 unmittelbar im Nutgrund befestigt. In der Nut ist ein Schallabsorber 8 angeordnet, welcher einen Schallschutz verbessert. Das Dichtmittel 7 ist in einen Kanal 91 des ersten Haltemittels 9 eingezogen und nicht in der Höhe einstellbar.At the casserole seal according to Fig. 23 In contrast, a first holding means 9 is fastened by means of screws 1 directly in the groove base. In the groove, a sound absorber 8 is arranged, which improves sound insulation. The sealing means 7 is drawn into a channel 91 of the first holding means 9 and not adjustable in height.

Bei den Varianten nach Fig. 22 und Fig. 23 kann das Material des Schallabsorbers 8 durch ein intumeszierendes Material ersetzt sein. Ebenso ist es möglich, dass der Schallabsorber intumeszierende Eigenschaften hat.In the variants after FIGS. 22 and 23 For example, the material of the sound absorber 8 may be replaced by an intumescent material. It is also possible that the sound absorber has intumescent properties.

Bei der in der Figur 24 und 25 dargestellten automatischen Dichtung ist ein Gehäuse der Dichtung im Nutgrund angeordnet. Die Dichtung weist ein erstes Haltemittel 9 auf, welches zusammen mit einem Dichtmittel 7 eine Dichtleiste bildet. Im Grunde kann diese Dichtleiste 7, 9 der aus der Fig. 4 bekannten Dichtleiste 4 mit einem Kanal zur Aufnahme des Dichtmittels 7 entsprechen. Die Dichtleiste 7, 9 ist über einen Mechanismus mit dem Gehäuse 3 verbunden. Die Dichtung kann durch einen Auslöser, der möglicherweise unabhängig vom Schließen oder Öffnen der mit dieser Dichtung ausgestatteten Tür betätigt werden kann, in einen abgesenkten Zustand gebracht werden, bei dem das Dichtmittel 7 am Fußboden B anliegt. In diesem Zustand kann eine Luftdurchtrittöffnung L, die durch die Unterseite des Türflügels T und den Fußboden B begrenzt wird, gegen einen Luftdurchtritt gesperrt sein (Fig. 25). Liegt dagegen eine Druckdifferenz in einer Richtung von der ersten Seite der Dichtung (in der Fig. links) zur zweiten Seite der Dichtung (in der Fig. rechts) vor, wird das Dichtmittel teilweise in ein Stellung geschwenkt, in welcher ein Luftdurchtritt möglich ist (in Fig. 25 gestrichelt dargestellt).When in the FIGS. 24 and 25 shown automatic seal, a housing of the seal is arranged in the groove bottom. The seal has a first holding means 9, which forms a sealing strip together with a sealing means 7. Basically, this sealing strip 7, 9 of the Fig. 4 known sealing strip 4 correspond to a channel for receiving the sealant 7. The sealing strip 7, 9 is connected via a mechanism to the housing 3. The seal can be brought into a lowered state by a trigger, which may possibly be actuated independently of the closing or opening of the door equipped with this seal, in which the sealant 7 rests on the floor B. In this state, an air passage opening L, which is bounded by the underside of the door leaf T and the floor B, be locked against an air passage ( Fig. 25 ). On the other hand, if there is a pressure difference in one direction from the first side of the gasket (left in the figure) to the second side of the gasket (right in the figure), the sealant is partially pivoted to a position where air passage is possible ( in Fig. 25 shown in dashed lines).
