Description

Die vorliegende Erfindung betrifft eine aktive Dichtungsvorrichtung und eine Schiebetür mit einer entsprechenden aktiven Dichtungsvorrichtung.The present invention relates to an active sealing device and a sliding door with a corresponding active sealing device.

Zum Abdichten von beweglichen Teilen, so wie beispielsweise Schiebetürflügeln gegenüber unbeweglichen Teilen, so wie beispielsweise einer Wand oder einer Verkleidung werden üblicherweise Bürstendichtungen verwendet. Bürstendichtungen wirken einem Verschieben des beweglichen Teils gegenüber dem nicht beweglichen Teil lediglich mit einer sehr geringen Haltekraft entgegen, so dass ein gegenseitiges Verschieben beider Teile leicht möglich ist. Jedoch sind Bürstendichtungen hinsichtlich Schallschutz, Rauchschutz oder dem Schutz gegen Zugluft nicht optimal, da diese weiterhin einen verminderten Luftaustausch zwischen den voneinander zu trennenden Raumbereichen ermöglicht.Brush seals are commonly used to seal moving parts, such as sliding door panels, against immovable parts, such as a wall or panel. Brush seals counteract a displacement of the movable part relative to the non-movable part only with a very low holding force, so that a mutual displacement of both parts is easily possible. However, brush seals are not optimal with regard to sound insulation, smoke protection or protection against drafts, since this further enables a reduced air exchange between the areas to be separated.

Zum Lösen dieses Problems sind aus dem Stand der Technik Dichtungen bekannt, die auf eine Dichtfläche hinbewegt und von dieser Dichtfläche wieder wegbewegt werden können. Aus der DE 10 2010 011 770 A1 ist eine Schiebetür bekannt, die mittels einer Halteschiene an einem Verfahrschlitten befestigt ist. Der Verfahrschlitten ist in einer Laufschiene in einer Verkleidung angeordnet, so dass die Schiebetür gegenüber der Verkleidung und gegenüber einer Türöffnung verschoben werden kann. In der Halteschiene ist eine Aufnahme vorgesehen, in der eine Dichtung angeordnet ist. Während einer Verfahrbewegung der Schiebetür ist die Dichtung nicht ausgelöst, so dass die Dichtung nicht an der Verkleidung bzw. einer Dichtfläche anliegt. In der Schließstellung der Schiebetür wird die Dichtung ausgelöst, so dass ein Dichtungsprofil der Dichtung an der Verkleidung anliegt. Somit bietet diese Art von Dichtung einen verbesserten Schallschutz, Rauchschutz und Schutz gegenüber Zugluft.To solve this problem, seals are known from the prior art which can be moved towards a sealing surface and moved away from this sealing surface again. From the DE 10 2010 011 770 A1 a sliding door is known, which is fastened to a traversing slide by means of a holding rail. The carriage is arranged in a running track in a panel, so that the sliding door can be moved relative to the panel and against a door opening. A receptacle is provided in the holding rail, in which a seal is arranged. The seal is not triggered during a traversing movement of the sliding door, so that the seal does not abut the panel or a sealing surface. In the closed position of the sliding door, the seal is triggered, so that a sealing profile of the seal rests on the panel. This type of seal thus offers improved sound insulation, smoke protection and protection against drafts.

Jedoch ist die in der DE 10 2010 011 770 A1 offenbarte Dichtung in ihrem Aufbau kompliziert. Weiterhin wird für den Zusammenbau der Dichtung und für den Einbau dieser in die Halteschiene Werkzeug benötigt, was den Zeitaufwand und die Kosten für den Einbau insbesondere vor Ort erhöht.However, the one in the DE 10 2010 011 770 A1 disclosed seal complicated in its structure. Furthermore, tools are required for assembling the seal and for installing it in the holding rail, which increases the time and costs for the installation, particularly on site.

Eine gattungsbildende Dichtung ist beispielsweise aus der EP 0 011 336 A1 bekannt geworden. Diese Vorveröffentlichung umfasst eine absenkbare Dichtung, deren eines Dichtungsende mittels einer Befestigungseinrichtung beispielsweise in einem entsprechenden Gehäuse feststehend verankert ist. Von dort hängt die Dichtung frei herab, ohne den Boden zu berühren. Am unteren Ende ist die Folie über einen in Seitenansicht bogenförmigen Abschnitt wieder nach oben zurückgeführt, und zwar zu einem Absenkteil 2, das eine Dicke aufweist, die etwa dem drei- bis vierfachen der Folie entspricht. Hier ist die Folie mit ihrem anderen Rand eingehängt. Durch diese Anordnung hängt die Folie frei der Schwerkraft folgend nach unten herab. Soll die Dichtung wirksam werden, wird das Absenkteil 2 in einer entsprechenden Führungseinrichtung nach unten verfahren, wodurch der darüber gehaltene zweite Folienrand ebenfalls mit abgesenkt wird. Dabei kann das Absenkteil 2 soweit abgesenkt werden, bis der der Schwerkraft folgende frei herabhängende kurvige Abschnitt der Dichtung auf dem Boden aufliegt und damit als Vertikaldichtung wirksam ist.A generic seal is for example from the EP 0 011 336 A1 known. This prior publication comprises a lowerable seal, one end of which is fixedly anchored by means of a fastening device, for example in a corresponding housing. From there, the seal hangs freely without touching the floor. At the lower end, the film is led back upwards via a section which is curved in a side view, namely to a lowering part 2 which has a thickness which corresponds approximately to three to four times the film. Here the film is attached with its other edge. With this arrangement, the film hangs down freely under gravity. If the seal is to become effective, the lowering part 2 is moved downwards in a corresponding guide device, as a result of which the second film edge held above it is also lowered. The lowering part 2 can so far be lowered until the freely hanging, curving portion of the seal following gravity rests on the floor and is thus effective as a vertical seal.

Aus der DE 23 52 873 A1 ist ebenfalls eine aktive Dichtungsvorrichtung gemäß dem dortigen Ausführungsbeispiel nach Figur 20 zu entnehmen, das in funktioneller und technischer Hinsicht identisch ausgebildet ist wie in dem vorstehend genannten Stand der Technik. Auch hier hängt die Folie der Schwerkraft folgend frei herab, wobei über ein Absenkteil der frei herabhängende eine Teil der Folie nach unten herab gelassen wird, bis ein mittlerer, in Seitenansicht kurviger Abschnitt der Folie den Boden berührt und als Vertikaldichtung wirksam ist.From the DE 23 52 873 A1 an active sealing device according to the exemplary embodiment according to FIG. 20 can also be seen, which is of identical functional and technical design as in the aforementioned prior art. Here, too, the film hangs freely due to gravity, with a part of the film hanging freely down over a lowering part until a central section of the film which is curved in a side view touches the floor and is effective as a vertical seal.

Aus der US 4,453,584 A ist eine aktive Dichtungsvorrichtung zu entnehmen, die eine mehrlagige Folie umfasst, die von einer oben liegenden Walze entsprechend der Drehbewegung der Walze frei nach unten hängend herab gelassen oder angehoben werden kann. Dabei ist eine äußere Folie vorgesehen, die von der oben liegenden Walze herab gelassen, um eine unten innerhalb der Folienschlaufe frei drehbare Rolle herumgeführt und wieder zu der oben liegenden Anheb- und Absenkwalze zurückgeführt ist. Innenliegend ist eine Folie vorgesehen, die von der Abrollwalze herabgeführt und um einen unten liegenden bogenförmigen Abschnitt wieder zur oben liegenden Walze zurückgeführt wird. Es ist unten liegend eine schmäler dimensionierte Rolle eingeführt, um jeweils die beiden parallel zueinander laufenden Folienabschnitte der gleichen Folie auf Abstand zu halten. Die Folien werden der reinen Schwerkraft folgend senkrecht herabgelassen oder angehoben, um eine Vertikaldichtung zu bilden.From the US 4,453,584 A an active sealing device can be seen, which comprises a multilayer film, which can be lowered or lifted freely suspended from an overhead roller in accordance with the rotational movement of the roller. In this case, an outer film is provided, which is let down from the roller above, is guided around a roller which can be freely rotated at the bottom inside the film loop, and is fed back to the lifting and lowering roller lying above. A film is provided on the inside, which is guided down from the unrolling roller and is returned to the roller above by an arcuate section lying at the bottom. A narrower dimensioned roller is inserted at the bottom in order to keep the two film sections of the same film running parallel to one another at a distance. The films are lowered or lifted vertically following pure gravity to form a vertical seal.

Aufgabe der vorliegenden Erfindung ist demgegenüber eine verbesserte Dichtungsvorrichtung bereitzustellen, die zuverlässig einen Luftaustausch zwischen zwei voneinander zu trennenden Raumbereichen unterbindet, die zumindest teilweise werkzeugfrei zusammensetzbar und montierbar und darüber hinaus kostengünstig in ihrer Herstellung ist.In contrast, the object of the present invention is to provide an improved sealing device which reliably prevents air exchange between two spatial areas to be separated from one another, which can be assembled and assembled at least partially without tools and which is also inexpensive to produce.

Diese Aufgabe wird durch eine aktive Dichtungsvorrichtung gemäß Anspruch 1 und durch eine Schiebetür gemäß Anspruch 13 gelöst. Vorteilhafte Ausführungen der Dichtungsvorrichtung sind in den abhängigen Ansprüchen beschrieben.This object is achieved by an active sealing device according to claim 1 and by a sliding door according to claim 13. Advantageous embodiments of the sealing device are described in the dependent claims.

Die erfindungsgemäße aktive Dichtungsvorrichtung umfasst eine flexible Dichtungsfolie, die in einem Führungskanal einer Führungseinrichtung verschiebbar angeordnet ist, wobei der Führungskanal durch zwei zueinander beabstandete Führungsflächen gebildet ist. Der Führungskanal weist einen Kanaleingang und einen Kanalausgang auf. Ein erstes Ende der Dichtungsfolie ist an einem kanaleingangsseitig angeordneten Antriebsglied befestigt. Die Dichtungsfolie tritt durch einen Kanaleingang in den Führungskanal ein, und tritt über den Kanalausgang aus dem Führungskanal aus. Ein zweites Ende der Dichtungsfolie ist außerhalb des Führungskanals und/oder im Bereich des Kanalausgangs an der Führungseinrichtung befestigt. Das Antriebsglied ist zwischen einer Einfahrposition und einer Ausfahrposition beweglich, wobei durch Überführen des Antriebsglieds von der Einfahrposition in die Ausfahrposition die Dichtungsfolie durch den Führungskanal geschoben wird, so dass ein Teil der Dichtungsfolie aus dem Kanalausgang austritt und im Bereich des Kanalausgangs eine Schlauchdichtung bildet. Durch Überführen des Antriebsglieds von der Ausfahrposition in die Einfahrposition wird die Dichtungsfolie durch den Führungskanal in Richtung Kanaleingang gezogen, so dass die Schlauchdichtung im Bereich des Kanalausgangs wieder rückgebildet wird.The active sealing device according to the invention comprises a flexible sealing film which is arranged displaceably in a guide channel of a guide device, the guide channel being formed by two guide surfaces spaced apart from one another. The guide channel has a channel input and a channel output. A first end of the sealing film is fastened to a drive member arranged on the channel inlet side. The sealing film enters the guide channel through a channel entrance and exits the guide channel via the channel exit. A second end of the sealing film is attached to the guide device outside the guide channel and / or in the area of the channel exit. The drive member is movable between a retracted position and an extended position, the sealing film being pushed through the guide channel by moving the drive member from the retracted position to the extended position, so that part of the sealing film emerges from the channel outlet and forms a hose seal in the area of the channel outlet. By moving the drive member from the extended position to the retracted position, the sealing film is pulled through the guide channel in the direction of the channel entrance, see above that the hose seal is re-formed in the area of the duct outlet.

Die erfindungsgemäße aktive Dichtungsvorrichtung ermöglicht die Erzeugung einer Schlauchdichtung und somit eines Dichtprofils lediglich bei Bedarf. Somit wird beispielsweise bei einer mit der erfindungsgemäßen Dichtungsvorrichtung ausgestatteten Schiebetür einer Verschiebebewegung eines Schiebetürflügels bei eingefahrenem Antriebsglied durch die Dichtungsvorrichtung nicht entgegengewirkt, wohingegen beispielsweise in einer Schließposition des Schiebflügels das Antriebsglied ausgefahren werden kann, so dass ein zuverlässiger Schallschutz, Rauchschutz und Schutz gegen Zugluft gegeben ist. Für die erfindungsgemäße Dichtvorrichtung sind lediglich wenige Einzelteile notwendig, so dass die aktive Dichtungsvorrichtung nicht wartungsintensiv ist. Darüber hinaus ist die aktive Dichtungsvorrichtung einfach und kostengünstig herstellbar.The active sealing device according to the invention enables the creation of a hose seal and thus a sealing profile only when required. Thus, for example, in a sliding door equipped with the sealing device according to the invention, a sliding movement of a sliding door leaf when the drive element is retracted is not counteracted by the sealing device, whereas, for example, the drive element can be extended in a closed position of the sliding leaf, so that reliable sound insulation, smoke protection and protection against drafts are provided . Only a few individual parts are necessary for the sealing device according to the invention, so that the active sealing device is not maintenance-intensive. In addition, the active sealing device is simple and inexpensive to manufacture.

Um eine zuverlässige Führung der Dichtungsfolie und ein Auflaufen der Dichtungsfolie im Führungskanal bei einem Verschieben der Dichtungsfolie vom Kanaleingang zum Kanalausgang zwecks Erzeugung der Schlauchdichtung zu vermeiden, ist ein Abstand zwischen den zwei Führungsflächen vorzugsweise größer oder gleich einer Dicke der Dichtungsfolie. Der Abstand der zwei Führungsflächen entspricht der Dicke der Dichtungsfolie zuzüglich einem Zusatz, der vorzugsweise zwischen 1% und 5%, weiter vorzugsweise zwischen 5% und 10%, weiter vorzugsweise zwischen 10% und 20%, weiter vorzugsweise zwischen 20% und 50%, oder weiter vorzugsweise zwischen 50% und 100% der Dicke der Dichtungsfolie entspricht. Vorzugsweise ist zur Vermeidung des Auflaufens der Dichtungsfolie im Führungskanal der Abstand zwischen den Führungsflächen entlang einer gesamten Breitenerstreckung und entlang einer gesamten Längenerstreckung des Führungskanals gleichbleibend. Vorzugsweise weist dazu der Führungskanal eine entlang einer Bewegungsbahn der Dichtungsfolie gleichbleibend orientierte Krümmung auf. Die Dichtungsfolie kann vorzugsweise eine Vorbiegung aufweisen, die in ihrer Orientierung der Krümmung des Führungskanals entspricht, so dass dadurch ein Auflaufen der Dichtungsfolie im Führungskanal vermieden wird.In order to avoid reliable guiding of the sealing film and running of the sealing film in the guide channel when the sealing film is moved from the channel entrance to the channel exit in order to produce the hose seal, a distance between the two guide surfaces is preferably greater than or equal to a thickness of the sealing film. The distance between the two guide surfaces corresponds to the thickness of the sealing film plus an additive, which is preferably between 1% and 5%, more preferably between 5% and 10%, further preferably between 10% and 20%, further preferably between 20% and 50%, or more preferably between 50% and 100% of the thickness of the sealing film. To prevent the sealing film from running up in the guide channel, the distance between the guide surfaces is preferably along an entire width extension and along an entire length extension of the guide channel remains the same. For this purpose, the guide channel preferably has a curvature which is oriented in a constant manner along a movement path of the sealing film. The sealing film can preferably have a pre-bend which corresponds in its orientation to the curvature of the guide channel, so that this prevents the sealing film from running up in the guide channel.

Vorzugsweise umfasst das Antriebsglied eine drehbare Mitnehmerwelle, wobei durch Verdrehen des Antriebsglieds von der Einfahrposition in die Ausfahrposition die Dichtungsfolie von der Mitnehmerwelle teilweise abgerollt wird, und wobei durch Verdrehen des Antriebsglieds von der Ausfahrposition in die Einfahrposition die Dichtungsfolie auf der Mitnehmerwelle zumindest teilweise aufgerollt wird. Dabei dient die Umfangsfläche der Mitnehmerwelle auch als Führung für die Dichtungsfolie, so dass durch das Bereitstellen der Mitnehmerwelle ein Verschieben der Dichtungsfolie insbesondere vom Kanaleingang hin zum Kanalausgang zuverlässig ermöglicht wird, ohne dass die Dichtungsfolie aufläuft und unerwünschte Falten wirft.The drive member preferably comprises a rotatable driver shaft, the sealing film being partially rolled off from the driver shaft by rotating the drive member from the retracted position to the extended position, and wherein the sealing film is at least partially rolled up on the driver shaft by rotating the drive member from the extended position to the retracted position. The circumferential surface of the driver shaft also serves as a guide for the sealing film, so that by providing the driver shaft, the sealing film can be reliably moved, in particular from the channel entrance to the channel exit, without the sealing film running open and causing undesirable folds.

Vorzugsweise ist der Kanaleingang derart tangential unterhalb des Antriebsglieds angeordnet, dass bei einem Abrollen der Dichtungsfolie von dem Antriebsglied die Dichtungsfolie der Schwerkraft folgend durch den Kanaleingang in den Führungskanal bewegt bzw. geschoben wird. Durch eine Krümmung des Führungskanals auf die abzudichtende Fläche zu tritt die Dichtungsfolie aus dem Kanalausgang in Richtung der abzudichtenden Fläche aus, so dass die am Kanalausgang gebildete Schlauchdichtung auf die abzudichtende Fläche hin gedrückt wird.The channel entrance is preferably arranged tangentially below the drive member such that when the sealing film rolls off the drive member, the sealing sheet is moved or pushed into the guide channel through the channel entrance following gravity. Due to a curvature of the guide channel towards the surface to be sealed, the sealing film emerges from the channel outlet in the direction of the surface to be sealed, so that the hose seal formed at the channel outlet is pressed onto the surface to be sealed.

Vorzugsweise umfasst die Führungseinrichtung ein Basiselement und ein daran befestigbares Zusatzelement, wobei das Basiselement einer der beiden Führungsflächen und das Zusatzelement die andere der beiden Führungsflächen aufweist. Das Zusatzelement ist an dem Basiselement mittels einer an dem Basiselement vorgesehenen Befestigungseinrichtung derart befestigbar, dass sich die zwei Führungsflächen zueinander beabstandet gegenüberstehen und den Führungskanal bilden. Das Zusatzelement weist ferner eine Lagereinrichtung auf, in der das Antriebsglied drehbar gelagert ist. Durch einen entsprechenden modularen Aufbau der Dichtungsvorrichtung ist ein Zusammenbau insbesondere am Einbauort der aktiven Dichtungsvorrichtung erleichtert. Auch ist die Wartung einer entsprechenden aktiven Dichtungsvorrichtung erleichtert, da bei einem Defekt oder Verschleiß beispielsweise des Antriebsglieds oder der Dichtungsfolie diese einfach ausgetauscht werden können.The guide device preferably comprises a base element and an additional element which can be fastened thereon, wherein the base element of one of the two guide surfaces and the additional element has the other of the two guide surfaces. The additional element can be fastened to the base element by means of a fastening device provided on the base element in such a way that the two guide surfaces are spaced apart from one another and form the guide channel. The additional element also has a bearing device in which the drive member is rotatably mounted. A corresponding modular construction of the sealing device makes assembly easier, in particular at the installation location of the active sealing device. The maintenance of a corresponding active sealing device is also made easier, since in the event of a defect or wear, for example of the drive member or the sealing film, these can be easily replaced.

Die Lagereinrichtung kann in Form einer Lagerschale realisiert sein. Weiterhin kann die Lagerschale alternativ zweiteilig ausgestaltet sein, wobei das Basiselement einen Teil der Lagerschale und das Zusatzelement einen anderen Teil der Lagerschale bilden.The bearing device can be implemented in the form of a bearing shell. Furthermore, the bearing shell can alternatively be configured in two parts, the base element forming part of the bearing shell and the additional element forming another part of the bearing shell.

Um eine Haftreibung zwischen dem Antriebsglied und der Dichtungsfolie zu erhöhen, so dass die Dichtungsfolie durch das Antriebsglied zuverlässig in Richtung des Kanalausgangs geschoben wird, umfasst das Antriebsglied der erfindungsgemäßen Dichtungsvorrichtung vorzugsweise ferner eine Gleitwelle mit einer axialen Aussparung, in der die Mitnehmerwelle aufgenommen ist, so dass die Mitnehmerwelle mit der Gleitwelle drehfest verbunden. Dabei ist die Dichtungsfolie an der Mitnehmerwelle und/oder an der Gleitwelle befestigt und kann zumindest teilweise auf der Gleitwelle aufgerollt und zumindest teilweise von der Gleitwelle abgerollt werden.In order to increase static friction between the drive member and the sealing film, so that the sealing film is reliably pushed by the drive member in the direction of the channel outlet, the drive member of the sealing device according to the invention preferably further comprises a sliding shaft with an axial recess in which the driver shaft is received, so that the driver shaft is rotatably connected to the sliding shaft. The sealing film is attached to the drive shaft and / or to the slide shaft and can be rolled up at least partially on the slide shaft and at least partially rolled off the slide shaft.

Für eine weitere Vereinfachung der Befestigung des Zusatzelementes an dem Basiselement sind die Befestigungseinrichtung und das Zusatzelement vorzugsweise derart gestaltet, dass das Zusatzelement samt Antriebsglied an dem Basiselement mittels einer Schnappverbindung befestigt werden kann. Vorzugsweise kann dabei das Zusatzelement an dem Basiselement werkzeugfrei befestigt werden.To further simplify the fastening of the additional element to the base element, the fastening device and the additional element are preferably designed such that the additional element together with the drive member can be fastened to the base element by means of a snap connection. The additional element can preferably be attached to the base element without tools.

Für eine weitere Herstellungsvereinfachung und Kostenreduzierung der erfindungsgemäßen aktiven Dichtungsvorrichtung kann das Basiselement ein Strangpressteil und/oder das Zusatzelement ein Strangpressteil und/oder das Antriebsglied ein Strangpressteil sein. Die Strangpressteile sind beliebig ablängbar, so dass die erfindungsgemäße aktive Dichtungsvorrichtung einfach beispielsweise an beliebige Flügeltürbreiten angepasst werden kann.To further simplify production and reduce costs of the active sealing device according to the invention, the base element can be an extruded part and / or the additional element can be an extruded part and / or the drive member can be an extruded part. The extruded parts can be cut to length, so that the active sealing device according to the invention can be easily adapted, for example, to any wing door widths.

In der nun folgenden Beschreibung bezeichnen gleiche Bezugszeichen gleiche Bauteile bzw. gleiche Merkmale, so dass eine in Bezug auf eine Figur durchgeführte Beschreibung bezüglich eines Bauteils auch für die anderen Figuren gilt, so dass eine wiederholende Beschreibung vermieden wird.In the following description, the same reference numerals designate the same components or the same features, so that a description of one component with respect to one figure also applies to the other figures, so that a repetitive description is avoided.

Figur 1 zeigt eine Querschnitt durch die erfindungemäße aktive Dichtungsvorrichtung im eingefahrenen bzw. inaktiven Zustand, in dem die Dichtungsvorrichtung nicht an einer abzudichtenden Fläche anliegt, wohingegen Figur 2 die gleiche Dichtungsvorrichtung im ausgefahrenen bzw. aktiven Zustand zeigt, in dem eine Schlauchdichtung 16 an einer abzudichtenden Fläche anliegt. Figure 1 shows a cross section through the active sealing device according to the invention in the retracted or inactive state, in which the sealing device is not in contact with a surface to be sealed, whereas Figure 2 shows the same sealing device in the extended or active state, in which a hose seal 16 rests on a surface to be sealed.

Die erfindungsgemäße Dichtungsvorrichtung umfasst eine als flexibles Flächenmaterial ausgebildete Dichtungsfolie 10, die aus Silikon, einer Gummimischung, einem Kunststoff, einem textilen Gewebe oder Aluminium besteht oder zumindest eines dieser Materialien umfasst. Weiterhin umfasst die Dichtungsvorrichtung ein Antriebsglied 30, das wiederum eine Mitnehmerwelle 32 und eine Gleitwelle 34 umfasst. Die Mitnehmerwelle 32 weist einen sechseckigen Querschnitt auf, und die Außenfläche der Gleitwelle 34 weist einen kreisförmigen bzw. annähernd kreisförmigen Querschnitt auf. Die Gleitwelle 34 weist eine axiale Aussparung auf, die einen im Wesentlichen dem Querschnitt der Mitnehmerwelle entsprechenden sechseckigen Querschnitt aufweist. Die Mitnehmerwelle 32 ist in der axialen Aussparung der Gleitwelle 34 aufgenommen und drehfest mit der Gleitwelle 34 verbunden. Prinzipiell kann die Mitnehmerwelle 32 jeden beliebigen von einem kreisrunden Querschnitt abweichenden Querschnitt aufweisen, und die axiale Aussparung in der Gleitwelle 34 kann dann einen entsprechenden Querschnitt aufweisen, so dass eine Kraftübertragung von der Mitnehmerwelle 32 auf die Gleitwelle 34 ermöglicht ist.The sealing device according to the invention comprises a sealing film 10 designed as a flexible surface material, which consists of silicone, a rubber mixture, a plastic, a textile fabric or aluminum or comprises at least one of these materials. Furthermore, the sealing device comprises a drive member 30, which in turn comprises a driver shaft 32 and a sliding shaft 34. The drive shaft 32 has a hexagonal cross section, and the outer surface of the sliding shaft 34 has a circular or approximately circular cross section. The sliding shaft 34 has an axial recess which has a hexagonal cross section which essentially corresponds to the cross section of the driving shaft. The driver shaft 32 is in the axial recess Sliding shaft 34 added and rotatably connected to the sliding shaft 34. In principle, the driver shaft 32 can have any cross section that deviates from a circular cross section, and the axial recess in the slide shaft 34 can then have a corresponding cross section, so that a force transmission from the driver shaft 32 to the slide shaft 34 is made possible.

Sowohl die Mitnehmerwelle 32 als auch die Gleitwelle 34 weisen entlang ihrer axialen Erstreckung nutförmige radiale Aussparungen auf. Die Mitnehmerwelle 32 weist darüber hinaus eine im Querschnitt mittig oder annähernd mittig angeordnete zylindrische und axial verlaufende Aussparung auf, in die die nutförmige radiale Aussparung mündet. Dabei ist der Durchmesser der zylindrischen Aussparung größer als die Querausdehnung der nutförmigen Aussparungen. Die Mitnehmerwelle 32 und die Gleitwelle 34 sind derart zueinander orientiert, dass die jeweiligen radialen Aussparungen ineinander übergehen.Both the driver shaft 32 and the sliding shaft 34 have groove-shaped radial recesses along their axial extension. The driver shaft 32 also has a cylindrical and axially extending recess which is arranged centrally or approximately centrally in the cross section and into which the groove-shaped radial recess opens. The diameter of the cylindrical recess is larger than the transverse extent of the groove-shaped recesses. The driver shaft 32 and the sliding shaft 34 are oriented towards one another in such a way that the respective radial cutouts merge into one another.

Ein erstes Ende 12 der Dichtungsfolie 10 weist eine zylinderförmige Verdickung auf, die so dimensioniert ist, dass diese von einer der Stirnseiten des Antriebsglieds 30 in die zylindrische Aussparung der Mitnehmerwelle 32 eingeschoben werden kann. Durch Einschieben des ersten Endes 12 in die zylindrische Aussparung der Mitnehmerwelle 32 wird die Dichtungsfolie 10 mit dem Antriebsglied 30 verbunden. Dabei ragt die übrige Dichtungsfolie 10 aus den nutförmigen Aussparungen heraus.A first end 12 of the sealing film 10 has a cylindrical thickening which is dimensioned such that it can be inserted into the cylindrical recess of the drive shaft 32 from one of the end faces of the drive member 30. By pushing the first end 12 into the cylindrical recess of the drive shaft 32, the sealing film 10 is connected to the drive member 30. The remaining sealing film 10 protrudes from the groove-shaped recesses.

Weiterhin umfasst die Dichtungsvorrichtung eine Führungseinrichtung (20), die in dem hier dargestellten Ausführungsbeispiel als ein zweiteiliges Gehäuse mit einem Basiselement 21 und einem Zusatzelement 24 ausgestaltet ist, wobei das Zusatzelement 24 mit dem Basiselement 21 verbunden ist. Für die Verbindung des Zusatzelements 24 mit dem Basiselement 21 umfasst das Basiselement 21 ein Befestigungseinrichtung 23. Die Befestigungseinrichtung 23 hat die Form einer Befestigungsnut 23, die zwischen dem Basiselementkörper und einem mit diesem verbundenen elastischen Flügelteil 23' gebildet ist. Das Zusatzelement 24 umfasst eine Haltefeder 23", die in die Befestigungsnut 23 eingeschoben werden kann. Durch Einschieben der Haltefeder 23" in die Befestigungsnut 23 wird der Flügelteil 23' elastisch verformt und rastet am Ende der Einschubbewegung in eine dafür vorgesehene Mulde im Zusatzelement 24 ein, so dass das Zusatzelement 24 und das Basiselement 21 mittels einer lösbaren Schnappverbindung miteinander verbunden sind. Das Zusatzelement 24 ist somit werkzeugfrei an dem Basiselement 21 befestigbar.Furthermore, the sealing device comprises a guide device (20), which in the exemplary embodiment shown here is designed as a two-part housing with a base element 21 and an additional element 24, the additional element 24 being connected to the base element 21 is. For the connection of the additional element 24 to the base element 21, the base element 21 comprises a fastening device 23. The fastening device 23 has the form of a fastening groove 23, which is formed between the base element body and an elastic wing part 23 ′ connected to it. The additional element 24 comprises a retaining spring 23 ″ which can be inserted into the fastening groove 23. By inserting the retaining spring 23 ″ into the fastening groove 23, the wing part 23 ′ is elastically deformed and at the end of the insertion movement engages in a recess provided in the additional element 24 , so that the additional element 24 and the base element 21 are connected to one another by means of a releasable snap connection. The additional element 24 can thus be attached to the base element 21 without tools.

Das Zusatzelement 24 weist eine Lagereinrichtung 26 in Form einer im Wesentlichen teilzylinderförmgen Lagerschale 26 auf. Die Lagerschale 26 ist derart gestaltet und dimensioniert, dass das Antriebsglied 30 samt mit diesem verbundener Dichtungsfolie 10 von dieser drehbar aufnehmbar ist. Zum Aufnehmen des Antriebsglieds 30 samt mit diesem verbundener Dichtungsfolie 10 können diese über eine der Stirnseiten in die Lagerschale 26 des Zusatzelements 24 eingeschoben werden.The additional element 24 has a bearing device 26 in the form of an essentially partially cylindrical bearing shell 26. The bearing shell 26 is designed and dimensioned such that the drive member 30 together with the sealing film 10 connected to it can be rotatably received by the latter. To receive the drive member 30 together with the sealing film 10 connected to it, these can be pushed into the bearing shell 26 of the additional element 24 via one of the end faces.

Das Basiselement 21 weist eine Lagerfläche 26' auf. Durch Verbinden des Zusatzelements 24 mit dem Basiselement 21 bildet die Lagerfläche 26' zusammen mit der Lagerschale 26 einen Lagerzylinder, in dem das Antriebsglied 30 zusammen mit der Dichtungsfolie 10 drehbar gelagert sind.The base element 21 has a bearing surface 26 '. By connecting the additional element 24 to the base element 21, the bearing surface 26 'forms together with the bearing shell 26 a bearing cylinder in which the drive member 30 together with the sealing film 10 are rotatably mounted.

Das Basiselement 21 weist ferner eine in die Lagerfläche 26' übergehende Führungsfläche 22 und das Zusatzelement 24 weist ferner eine weitere Führungsfläche 25 auf. Die Führungsflächen 22, 25 sind derart zueinander beabstandet angeordnet, dass diese einen Führungskanal 27 bilden. Die Dichtungsfolie 10 tritt dabei durch einen Kanaleingang 28 in den Führungskanal 27 ein und tritt durch einen Kanalausgang 29 aus dem Führungskanal 27 aus. Der Abstand zwischen den zwei Führungsflächen 22, 25 entspricht dabei der Dicke der Dichtungsfolie 10 zuzüglich einem Zusatzabstand, der vorzugsweise zwischen 1% und 5%, weiter vorzugsweise zwischen 5% und 10%, weiter vorzugsweise zwischen 10% und 20%, weiter vorzugsweise zwischen 20% und 50%, oder weiter vorzugsweise zwischen 50% und 100% der Dicke der Dichtungsfolie entspricht, so dass die Dichtungsfolie 10 in dem Führungskanal 28 verschiebbar ist. Durch eine derartige Dimensionierung des Führungskanals 27 wird ein Auflaufen der Dichtungsfolie 10 im Führungskanal 27 vermieden.The base element 21 also has a guide surface 22 which merges into the bearing surface 26 'and the additional element 24 also has a further guide surface 25. The guide surfaces 22, 25 are arranged at a distance from one another in such a way that they form a guide channel 27. The sealing film 10 enters the guide channel 27 through a channel inlet 28 and exits the guide channel 27 through a channel outlet 29. The distance between the two guide surfaces 22, 25 corresponds to the thickness of the sealing film 10 plus an additional distance, which is preferably between 1% and 5%, more preferably between 5% and 10%, further preferably between 10% and 20%, further preferably between 20% and 50%, or more preferably between 50% and 100% of the thickness of the sealing film corresponds, so that the sealing film 10 is displaceable in the guide channel 28. Such a dimensioning of the guide channel 27 prevents the sealing film 10 from running up in the guide channel 27.

Die Figuren zeigen, dass der Führungskanal 27 derart tangential unterhalb des Antriebsglieds 30 angeordnet ist, dass bei einem Abrollen der Dichtungsfolie 10 von dem Antriebsglied 30 die Dichtungsfolie 10 der Schwerkraft folgend durch den Kanaleingang 28 in den Führungskanal 27 bewegt bzw. geschoben wird.The figures show that the guide channel 27 is arranged tangentially below the drive member 30 such that when the sealing film 10 rolls off the drive member 30, the sealing film 10 is moved or pushed into the guide channel 27 through the channel entrance 28 following gravity.

Aus den Figuren ist ersichtlich, dass der Abstand zwischen den Führungsflächen 22, 25 entlang der Längenerstreckung des Führungskanals 27 gleichbleibend ist. Auch wenn es den Figuren aufgrund der Querschnittsdarstellung nicht zu entnehmen ist, ist der Abstand zwischen den Führungsflächen 22, 25 entlang einer Breitenerstreckung des Führungskanals 27 gleichbleibend. Weiterhin weist der Führungskanal 27 eine entlang der Bewegungsbahn der Dichtungsfolie 10 gleichbleibend orientierte Krümmung auf. Durch diese Maßnahmen wird ebenfalls ein Auflaufen der Dichtungsfolie 10 im Führungskanal 27 vermieden.It can be seen from the figures that the distance between the guide surfaces 22, 25 along the length of the guide channel 27 is constant. Even if it cannot be seen from the figures due to the cross-sectional representation, the distance between the guide surfaces 22, 25 along a width extension of the guide channel 27 remains constant. Furthermore, the guide channel 27 has a curvature which is oriented in a constant manner along the movement path of the sealing film 10. These measures also prevent the sealing film 10 from running up in the guide channel 27.

Ein zweites Ende 14 der Dichtungsfolie 10 ist außerhalb des Führungskanals 27 im Bereich des Kanalausgangs 29 an dem Zusatzelement 24 der Führungseinrichtung 20 befestigt. Bei der in den Figuren 1 und 2 dargestellten Dichtungsvorrichtung weist das zweite Ende 14 der Dichtungsfolie 10 eine zylinderförmige Verdickung auf, die in einer einseitig geöffneten hohlzylinderförmigen Ausnehmung des Zusatzelements 24 eingeschoben ist. Durch Einschieben des zweiten Endes 14 in die hohlzylinderförmige Ausnehmung des Zusatzelements 24 ist die Dichtungsfolie 10 mit dem Zusatzelement 24 und somit mit der Führungseinrichtung 20 verbunden. Aufgrund der Verbindung der Dichtungsfolie 10 mit dem Zusatzelement 24 außerhalb des Führungskanals 27 umschließt die Dichtungsfolie 10 eine abgerundete Kante 24' des Zusatzelements 24, so dass die Dichtungsfolie 10 im Bereich von deren zweitem Ende 16 umgeklappt ist.A second end 14 of the sealing film 10 is fastened outside the guide channel 27 in the region of the channel outlet 29 to the additional element 24 of the guide device 20. In the in the Figures 1 and 2nd Sealing device shown, the second end 14 of the sealing film 10 has a cylindrical thickening, which is inserted into a hollow cylindrical recess of the additional element 24 open on one side. By pushing the second end 14 into the hollow cylindrical recess of the additional element 24, the sealing film 10 is connected to the additional element 24 and thus to the guide device 20. Due to the connection of the sealing film 10 to the additional element 24 outside the guide channel 27, the sealing film 10 encloses a rounded edge 24 'of the additional element 24, so that the sealing film 10 is folded over in the region of its second end 16.

Das Antriebsglied 30 ist zwischen einer in Figur 1 gezeigten Einfahrposition und einer in Figur 2 gezeigten Ausfahrposition drehbar. Durch Verdrehen des Antriebsglieds 30 von der Einfahrposition entgegen des Uhrzeigersinns in die Ausfahrposition wird die Dichtungsfolie 10 durch den Führungskanal 27 in Richtung des Kanalausgangs 29 geschoben. Die Dichtungsfolie 10 löst sich dabei von der Kante 24' des Zusatzelements 24 und bildet im Bereich des Kanalausgangs 29 eine Schlauchdichtung 16 (Figur 2). In Figur 2 ist die so gebildete Schlauchdichtung 16 gegen einen im Querschnitt dargestellten Flügel 50 einer Schiebetür gedrückt, so dass die Dichtungsvorrichtung einen sich oberhalb der Schlauchdichtung 16 befindlichen Raumbereich von einem sich unterhalb der Schlauchdichtung 16 befindlichen Raumbereich trennt. Aufgrund der Krümmung des Führungskanals 27 tritt die Dichtungsfolie 10 aus dem Kanalausgang 29 in Richtung der abzudichtenden Fläche aus, so dass die am Kanalausgang 29 gebildete Schlauchdichtung 16 auf den Flügel 50 hin gedrückt wird.The drive member 30 is between one in Figure 1 Retracted position shown and one in Figure 2 shown extended position rotatable. By rotating the drive member 30 from the retracted position counterclockwise to the extended position, the sealing film 10 is pushed through the guide channel 27 in the direction of the channel outlet 29. The sealing film 10 detaches from the edge 24 'of the additional element 24 and forms a hose seal 16 in the region of the channel outlet 29 ( Figure 2 ). In Figure 2 the hose seal 16 thus formed is pressed against a wing 50 of a sliding door shown in cross section, so that the sealing device separates a space located above the hose seal 16 from a space located below the hose seal 16. Due to the curvature of the guide channel 27, the sealing film 10 emerges from the channel outlet 29 in the direction of the surface to be sealed, so that the hose seal formed at the channel outlet 29 16 is pressed onto the wing 50.

Durch Verdrehen des Antriebsglieds 30 von der Ausfahrposition im Uhrzeigersinn in die Einfahrposition wird die Dichtungsfolie 10 durch den Kanalausgang 29 in den Führungskanal 27 in Richtung des Kanaleingangs 28 gezogen. Dabei legt sich die Dichtungsfolie 10 wieder an die Kante 24' des Zusatzelements 24 an und die Schlauchdichtung 16 wird zurückgebildet.By rotating the drive member 30 clockwise from the extended position into the retracted position, the sealing film 10 is drawn through the channel outlet 29 into the guide channel 27 in the direction of the channel inlet 28. The sealing film 10 then rests against the edge 24 'of the additional element 24 and the hose seal 16 is regressed.

Der Antrieb des Antriebsglieds 30 ist in den Figuren nicht dargestellt und kann mittels einer Antriebseinrichtung in Form eines Elektromotors, eines pneumatischen Antriebs oder durch ein bewegliches Teil erfolgen, das gegen einen Anschlag stößt und mit seiner Bewegung eine Drehbewegung des Antriebsglieds 30 bewirkt bzw. erzeugt. Die Antriebseinrichtung ist dabei mit der Mitnehmerwelle 32 bewegungsgekoppelt. Vorzugsweise besteht die Mitnehmerwelle 32 daher aus Aluminium, einer Aluminiumlegierung, Stahl oder einer Stahllegierung. Die Gleitwelle 34 hingegen kann aus einem Kunststoff gebildet sein.The drive of the drive member 30 is not shown in the figures and can be carried out by means of a drive device in the form of an electric motor, a pneumatic drive or by a movable part which abuts a stop and causes or generates a rotary movement of the drive member 30 with its movement. The drive device is motion-coupled to the driver shaft 32. The driver shaft 32 is therefore preferably made of aluminum, an aluminum alloy, steel or a steel alloy. The sliding shaft 34, however, can be formed from a plastic.

Figur 3 zeigt einen Querschnitt durch eine Schiebetür mit einer erfindungsgemäßen Dichtungsvorrichtung im eingefahrenen bzw. inaktiven Zustand, und Figur 4 zeigt eine Vergrößerung des in Figur 3 umrandeten Bereichs. Die in den Figuren 3 und 4 dargestellte Dichtungsvorrichtung unterscheidet sich von der in den Figuren 1 und 2 dargestellten Dichtungsvorrichtung dadurch, dass das zweiten Ende 14 der Dichtungsfolie 10 an der Führungseinrichtung 20 dadurch befestigt ist, dass das zweite Ende 14 an dem Zusatzelement 24 geklebt ist. Weiterhin weist die Mitnehmerwelle 32 keine axiale zylinderförmige Aussparung auf. Die Befestigung des ersten Endes 12 der Dichtungsfolie 10 an dem Antriebsglied 30 erfolgt durch Klemmung des ersten Endes 12 mittels der Gleitwelle 34. Der übrige Aufbau der in den Figuren 3 und 4 dargestellten Dichtungsvorrichtung und deren Funktionsweise ist identisch mit der in den Figuren 1 und 2 dargestellten Dichtungsvorrichtung. Figure 3 shows a cross section through a sliding door with a sealing device according to the invention in the retracted or inactive state, and Figure 4 shows an enlargement of the in Figure 3 outlined area. The in the Figures 3 and 4 sealing device shown differs from that in the Figures 1 and 2nd shown sealing device in that the second end 14 of the sealing film 10 is attached to the guide device 20 in that the second end 14 is glued to the additional element 24. Furthermore, the driver shaft 32 has no axial cylindrical recess. The first end 12 of the sealing film 10 is fastened to the drive member 30 by clamping the first end 12 by means of the sliding shaft 34. The remaining structure of the in the Figures 3 and 4 shown sealing device and its operation is identical to that in the Figures 1 and 2nd shown sealing device.

Die Dichtungsvorrichtung ist an einer oberhalb eines Durchgangs angeordneten Verkleidung 60 der Schiebetür befestigt. In der Verkleidung 60 ist eine horizontale Laufschiene 62 vorgesehen. Die Schiebetür umfasst einen Flügel 50, an dessen oberen Ende Haltewinkel 52 befestigt sind, die wiederum mit einem Laufwagen 54 mit Laufwagenrollen 56 verbunden sind. Die Laufwagenrollen 56 sind auf der Lauffläche 63 der Laufschiene 62 gelagert, so dass der Flügel 50 zwischen einer Schließstellung, in der der Durchgang mittels des Flügels 50 verschlossen ist, und einer Offenstellung verfahrbar ist, in der der Durchgang von dem Flügel 50 freigegeben ist.The sealing device is attached to a panel 60 of the sliding door arranged above a passage. A horizontal running track 62 is provided in the casing 60. The sliding door comprises a wing 50, at the upper end of which brackets 52 are fastened, which in turn are connected to a carriage 54 with carriage rollers 56. The carriage rollers 56 are mounted on the running surface 63 of the running rail 62, so that the wing 50 can be moved between a closed position in which the passage is closed by means of the wing 50 and an open position in which the passage is released from the wing 50.

In der in Figur 3 dargestellten Offenstellung des Flügels 50 befindet sich das Antriebsglied 30 der Dichtungsvorrichtung in der Einfahrposition, so dass im Bereich des Kanalausgangs 29 des Führungskanals 27 keine Schlauchdichtung 16 gebildet ist, die an dem Flügel 50 anliegt. Folglich behindert die Dichtungsvorrichtung in Offenstellung der Schiebetür 50 keine Verschiebebewegung des Flügels 50. Wenn die Schiebetür durch Verschieben des Flügels 50 in die den Durchgang verschließende Schließstellung überführt wird, wird das Antriebsglied 30 durch eine nicht dargestellte Antriebseinrichtung oder durch die Bewegung des Flügels 50 selber von der Einfahrposition in die Ausfahrposition überführt, so dass am Kanalausgang 29 der Dichtungsvorrichtung die in Figur 4 gestrichelt dargestellte Schlauchdichtung 16 gebildet wird, die gegen den gegenüber der Dichtungsvorrichtung angeordneten Flügel 50 gedrückt wird. Die Dichtungsvorrichtung und die Schlauchdichtung 16 erstrecken sich über die gesamt Breite des Flügels 50, so dass die Dichtungsvorrichtung aufgrund der Behinderung eines Luftaustausches zwischen einem sich oberhalb des Schlauchdichtung 16 und einem sich unterhalb der Schlauchdichtung 16 befindlichen Raumbereichs einen zuverlässigen Schutz vor Zugluft, einen zuverlässigen Rauchschutz und einen zuverlässigen Schallschutz ermöglicht, ohne eine Verschiebebewegung des Flügels 50 in Offenstellung der Schiebetür zu behindern.In the in Figure 3 shown open position of the wing 50, the drive member 30 of the sealing device is in the retracted position, so that in the region of the channel outlet 29 of the guide channel 27 no hose seal 16 is formed, which rests on the wing 50. Consequently, the sealing device in the open position of the sliding door 50 does not impede any sliding movement of the leaf 50. If the sliding door is moved into the closed position closing the passage by moving the leaf 50, the drive member 30 is actuated by a drive device (not shown) or by the movement of the leaf 50 itself the retracted position into the extended position, so that at the channel outlet 29 of the sealing device Figure 4 Hose seal 16 shown in dashed lines is formed, which is pressed against the wing 50 arranged opposite the sealing device. The sealing device and the hose seal 16 extend over the entire width of the wing 50, so that the sealing device enables reliable protection against drafts, reliable smoke protection and reliable sound insulation due to the hindrance of an air exchange between an area above the hose seal 16 and a space below the hose seal 16 , without hindering a sliding movement of the wing 50 in the open position of the sliding door.

Figur 5 zeigt einen Querschnitt durch eine Schiebetür mit einer abgewandelten Dichtungsvorrichtung im eingefahrenen bzw. inaktiven Zustand, und Figur 6 zeigt eine Vergrößerung des in Figur 5 umrandeten Bereichs. Die in den Figuren 5 und 6 dargestellte Dichtungsvorrichtung unterscheidet sich von den in den Figuren 1 bis 4 dargestellten Dichtungsvorrichtung dadurch, dass das Basiselement 21 keine Lagerfläche 26' aufweist, so dass das Antriebsglied 30 und die mit diesem verbundene Dichtungsfolie 10 lediglich durch die Lagereinrichtung 26 drehbar gelagert sind. Der übrige Aufbau und die Funktionsweise sind mit der in Bezug auf die Figuren 3 und 4 beschriebenen Dichtungsvorrichtung identisch. Figure 5 shows a cross section through a sliding door with a modified sealing device in the retracted or inactive state, and Figure 6 shows an enlargement of the in Figure 5 outlined area. The in the Figures 5 and 6 sealing device shown differs from that in the Figures 1 to 4 sealing device shown in that the base element 21 has no bearing surface 26 ', so that the drive member 30 and the sealing film 10 connected thereto are rotatably supported only by the bearing device 26. The rest of the structure and operation are the same with respect to the Figures 3 and 4 described sealing device identical.

Das Basiselement 21 und/oder das Zusatzelement 24 und/oder die Mitnehmerwelle 32 und/oder die Gleitwelle 34 können Strangpressteile sein, deren Produktion einfach, schnell und kostengünstig ist. Die Strangpressteile können einfach auf die gewünscht Länge, die der Breite des Türflügels 50 entsprechen kann, abgelängt werden.The base element 21 and / or the additional element 24 and / or the driving shaft 32 and / or the sliding shaft 34 can be extruded parts, the production of which is simple, quick and inexpensive. The extruded parts can simply be cut to the desired length, which can correspond to the width of the door leaf 50.
