Definitions

  • the present invention relates to a drop-down seal according to the preamble of claim 1 and a building part according to the preamble of claim 9.
  • Lowerable door seals usually consist essentially of a housing in the form of a downwardly open, U-shaped profile rail, a sealing strip held in this housing and displaceable relative to it with a sealing element and a drive mechanism for lowering or lifting the sealing strip.
  • the sealing strip usually lowers automatically when the door is closed, in that a compressive force acts in the longitudinal direction on an actuating rod or slide and activates the mechanical lowering mechanism.

Each leaf spring is attached to the slide itself with a first end which is adjacent to the end of the slide projecting from the housing. Each leaf spring is furthermore with its central area on the sealing strip and with its end remote from the protruding end of the slide on the housing attached. As a result, the pressure acting on the slide when the door is closed is transferred to the leaf springs, which bend and lower the sealing strip.

Description

TECHNISCHES GEBIETTECHNICAL AREA

Die vorliegende Erfindung betrifft eine Absenkdichtung gemäss Oberbegriff des Patentanspruchs 1 sowie ein Gebäudeteil gemäss Oberbegriff des Patentanspruchs 9.The present invention relates to a drop-down seal according to the preamble of claim 1 and a building part according to the preamble of claim 9.

STAND DER TECHNIKSTATE OF THE ART

Absenkdichtungen für Türen sind hinlänglich bekannt. Sie verhindern Lichtdurchlässe, bieten einen Schallschutz und können je nach Ausgestaltungsform auch Luftzirkulation unterbinden. Absenkbare Türdichtungen bestehen üblicherweise im Wesentlichen aus einem Gehäuse in Form einer nach unten offenen, u-förmigen Profilschiene, einer in diesem Gehäuse gehaltenen und relativ zu diesem verschiebbaren Dichtleiste mit einem Dichtelement und aus einem Antriebsmechanismus zum Absenken bzw. zum Anheben der Dichtleiste. Üblicherweise senkt sich die Dichtleiste automatisch beim Schliessen der Tür ab, indem eine Druckkraft in Längsrichtung auf einen Betätigungsstab oder Schieber wirkt und den mechanischen Absenkmechanismus in Betrieb setzt. Derartige Türdichtungen sind beispielsweise aus EP 0 338 974 , DE 299 16 090 und EP 0 509 961 bekannt.Drop-down seals for doors are well known. They prevent the passage of light, offer soundproofing and, depending on the design, can also prevent air circulation. Lowerable door seals usually consist essentially of a housing in the form of a downwardly open, U-shaped profile rail, a sealing strip held in this housing and displaceable relative to it with a sealing element and a drive mechanism for lowering or lifting the sealing strip. The sealing strip usually lowers automatically when the door is closed, in that a compressive force acts in the longitudinal direction on an actuating rod or slide and activates the mechanical lowering mechanism. Such door seals are made, for example EP 0 338 974 , DE 299 16 090 and EP 0 509 961 known.

Bewährte Absenkmechanismen, welche einseitig ausgelöst werden, sind beispielsweise in EP 0 509 961 und CH 688 741 beschrieben. Diese Absenkmechanismen verwenden eine oder mehrere hintereinander angeordnete Blattfedern. Jede Blattfeder ist mit einem ersten Ende, welches dem dem Gehäuse vorstehenden Ende des Schiebers benachbart ist, am Schieber selber befestigt. Jede Blattfeder ist ferner mit ihrem mittleren Bereich an der Dichtleiste und mit ihrem, dem vorstehenden Ende des Schiebers fernen Ende am Gehäuse befestigt. Dadurch wird der beim Schliessen der Tür auf den Schieber wirkende Druck auf die Blattfedern übertragen, diese beugen sich und senken die Dichtleiste ab.Proven lowering mechanisms that are triggered unilaterally are, for example, in EP 0 509 961 and CH 688 741 described. These lowering mechanisms use one or more leaf springs arranged one behind the other. Each leaf spring is attached to the slide itself with a first end which is adjacent to the end of the slide projecting from the housing. Each leaf spring is furthermore with its central area on the sealing strip and with its end remote from the protruding end of the slide on the housing attached. As a result, the pressure acting on the slide when the door is closed is transferred to the leaf springs, which bend and lower the sealing strip.

Auch EP 0 037 131 und DE 20 2011 001 104 U lösen den Absenkmechanismus über eine Druckkraft aus.Even EP 0 037 131 and DE 20 2011 001 104 U trigger the lowering mechanism via a pressure force.

In AU 2007 237 192 ist eine Absenkdichtung beschrieben, welche über Druckkraft ausgelöst wird. Diese Druckkraft wird über einen Hebelmechanismus in eine Zugkraft geändert, welche ebenfalls auf den Absenkmechanismus wirkt.In AU 2007 237 192 describes a drop-down seal that is triggered by pressure. This compressive force is changed into a tensile force via a lever mechanism, which also acts on the lowering mechanism.

DE 297 20 978 U und DE 26 57 279 offenbaren über Druckkraft ausgelöste Absenkdichtungen, welche über eine Zugkraft auch bei geöffneter Tür betätigt werden können. DE 297 20 978 U and DE 26 57 279 disclose drop-down seals triggered by compressive force, which can be actuated by tensile force even when the door is open.

Die lediglich nachveröffentlichte EP 2 634 350 A2 offenbart eine Absenkdichtung für eine Schiebetür, wobei die Dichtung sowohl durch Drücken wie auch mittels eines durch Zug zu betätigenden Auslösers betätigt werden kann.The only post-published EP 2 634 350 A2 discloses a drop-down seal for a sliding door, which seal can be actuated both by pushing and by means of a trigger to be actuated by pulling.

Für mehrteilige Schiebetüren, Schiebefenster und Trennwände sind jedoch keine praktikablen Dichtungslösungen bekannt.However, no practicable sealing solutions are known for multi-part sliding doors, sliding windows and partition walls.

DARSTELLUNG DER ERFINDUNGDISCLOSURE OF THE INVENTION

Es ist deshalb eine Aufgabe der Erfindung, eine Absenkdichtung zu schaffen, welche auch für mehrteilige Schiebetüren, mehrteilige Schiebefenster und Trennwände einsetzbar ist.It is therefore an object of the invention to create a drop-down seal which can also be used for multi-part sliding doors, multi-part sliding windows and partition walls.

Diese Aufgabe löst eine Absenkdichtung mit den Merkmalen des Anspruchs 1.This object is achieved by a drop-down seal with the features of claim 1.

Es ist eine weitere Aufgabe der Erfindung, ein Gebäudeteil, insbesondere eine mehrteilige Schiebetüre, ein mehrteiliges Schiebefenster und eine Trennwand, zu schaffen, welches über eine Absenkdichtung verfügt.It is a further object of the invention to create a part of the building, in particular a multi-part sliding door, a multi-part sliding window and a partition wall, which has a lowering seal.

Diese Aufgabe löst ein Gebäudeteil mit den Merkmalen des Anspruchs 9.This object is achieved by a part of the building with the features of claim 9.

Die erfindungsgemässe Absenkdichtung für ein Gebäudeteil weist ein Gehäuse, eine in diesem Gehäuse anhebbare und absenkbare Dichtleiste und einen federbelasteten Absenkmechanismus auf. Der Absenkmechanismus bewirkt eine automatische Absenkung der Dichtleiste beim Schliessen des Gebäudeteils. Er ist mit einem Schieber verbunden, welcher mit einem Ende dem Gehäuse vorsteht, vorzugsweise in Längsrichtung des Gehäuses. Der Absenkmechanismus umfasst mindestens eine Blattfeder, welche an einer ersten Befestigungsstelle mit dem Schieber verbunden ist, an einer zweiten Befestigungsstelle mit der Dichtleiste und an einer dritten Befestigungsstelle am Gehäuse befestigt ist. Die dritte Befestigungsstelle ist näher am vorstehenden Ende des Schiebers angeordnet als die erste Befestigungsstelle. Der Schieber aktiviert den Absenkmechanismus beim Schliessen des Gebäudeteils, wobei der Schieber die erste Befestigungsstelle der Blattfeder in Richtung des vorstehenden Endes zieht. Zur Betätigung des Schiebers ist ein Arm vorhanden, welcher dem Gehäuse seitlich vorsteht und welcher vorzugsweise mindestens annähernd senkrecht zur Längsrichtung der Dichtleiste verläuft. Dieser Arm ist mit dem Schieber wirkverbunden, mit ihm verbunden oder an ihm angeordnet.The lowering seal according to the invention for a part of a building has a housing, a sealing strip that can be raised and lowered in this housing, and a spring-loaded lowering mechanism. The lowering mechanism causes the sealing strip to automatically lower when the part of the building is closed. It is connected to a slide, one end of which protrudes from the housing, preferably in the longitudinal direction of the housing. The lowering mechanism comprises at least one leaf spring which is connected to the slide at a first fastening point, to the sealing strip at a second fastening point and to the housing at a third fastening point. The third fastening point is arranged closer to the protruding end of the slide than the first fastening point. The slide activates the lowering mechanism when the part of the building is closed, the slide pulling the first fastening point of the leaf spring in the direction of the protruding end. To operate the slide, there is an arm which protrudes laterally from the housing and which preferably runs at least approximately perpendicular to the longitudinal direction of the sealing strip. This arm is operatively connected to the slide, connected to it or arranged on it.

Diese mechanische Absenkdichtung lässt sich insbesondere in ein- und mehrteiligen verschiebbaren Gebäudeteilen verwenden. Da sie mit Zug und nicht mit Druck ausgelöst wird, lassen sich gänzlich andere Gebäudelösungen verwirklichen als mit den bekannten automatischen mechanischen Absenkdichtungen.This mechanical drop-down seal can be used in particular in one-part and multi-part sliding parts of the building. Since it is triggered with pull and not with pressure, completely different building solutions can be realized than with the known automatic mechanical lowering seals.

Vorteilhaft ist, dass trotz Auslösung auf Zug die Dichtung nicht höher oder breiter ausgebildet sein muss als die bekannten Dichtungen auf Druck. Insbesondere muss sie nicht grösser ausgebildet werden als die in CH 688 741 oder EP 0 338 974 beschriebenen Dichtungen.It is advantageous that, in spite of being triggered by tension, the seal does not have to be made higher or wider than the known seals under pressure. In particular, it does not have to be made larger than that in CH 688 741 or EP 0 338 974 described seals.

Vorzugsweise gleicht der Absenkmechanismus den bekannten Mechanismen. Er ist federbelastet, so dass er bei Entfallen einer äusseren Kraft die Dichtung wieder selbsttätig anhebt. Vorzugsweise weist er eine Dreiecksanordnung mit Hebeln und/oder Biegefedern auf, welche durch entsprechende Anordnung die Relativbewegung der Dichtleiste zum Gehäuse ermöglicht.The lowering mechanism preferably resembles the known mechanisms. It is spring-loaded so that it automatically lifts the seal again when there is no external force. Preferably, it has a triangular arrangement with levers and / or spiral springs, which through a corresponding arrangement, the relative movement of the sealing strip to Housing allows.

Die Blattfeder kann einstückig, aber auch mehrstückig ausgebildet sein, z.B. aus zwei Teilen bestehen, wobei je ein Ende der zwei Teile an der zweiten mittleren Befestigungsstelle befestigt ist.The leaf spring can be made in one piece, but also in several pieces, e.g. consist of two parts, with one end of each of the two parts being fastened to the second central fastening point.

Vorzugsweise weist der Schieber eine Kraftübertragungsstange auf, welche sich in Längsrichtung des Gehäuses in diesem erstreckt. Vorzugsweise erstreckt sich die Betätigungsstange annähernd über die gesamte Länge der Dichtleiste. Vorzugsweise erstreckt sie sich soweit, wie sich die Blattfedern in Längsrichtung des Gehäuses ausdehnen. Der Schieber umfasst vorzugsweise ferner eine dem Gehäuse vorstehende Betätigungsstange, welche mit der Kraftübertragungsstange fest verbunden ist. Vorzugsweise ist die mindestens eine Blattfeder an ihrer ersten Befestigungsstelle an der Kraftübertragungsstange befestigt. Die Kraftübertragungsstange ist vorzugsweise eine Flachstange, so dass sie einen relativ geringen Platzbedarf innerhalb der Dichtung ausweist und die Dichtung eine relativ geringe Bauhöhe besitzt.The slide preferably has a force transmission rod which extends in the housing in the longitudinal direction of the latter. The actuating rod preferably extends approximately over the entire length of the sealing strip. It preferably extends as far as the leaf springs extend in the longitudinal direction of the housing. The slide preferably further comprises an actuating rod which protrudes from the housing and which is firmly connected to the force transmission rod. The at least one leaf spring is preferably fastened to the force transmission rod at its first fastening point. The force transmission rod is preferably a flat rod, so that it requires a relatively small amount of space within the seal and the seal has a relatively low overall height.

Vorzugsweise ist die mindestens eine Blattfeder an ihrer zweiten Befestigungsstelle schwenkbar relativ zum Gehäuse gehalten. Dies ermöglicht eine annähernd senkrecht zur Längsrichtung der Dichtleiste verlaufende Absenkung der Dichtleiste.The at least one leaf spring is preferably held pivotably relative to the housing at its second fastening point. This enables the sealing strip to be lowered approximately perpendicular to the longitudinal direction of the sealing strip.

Um eine externe Zugkraft auf den Schieber zu übertragen, ist in einer bevorzugten Ausführungsform der Arm am Schieber bzw. an der Betätigungsstange des Schiebers angeordnet, wobei der Arm dem Gehäuse vorsteht und wobei der Arm mindestens annähernd senkrecht zur Längsrichtung der Dichtleiste verläuft. Vorzugsweise verläuft dieser Arm auch mindestens annähernd senkrecht zur Absenkrichtung der Dichtleiste. Vorzugsweise ist der Arm lösbar am Schieber befestigt. Dieser Arm bildet vorzugsweise eine Anschlagfläche zum Anliegen an ein ortsfestes oder bewegliches Nachbarbauteil des Gebäudeteils.In order to transmit an external tensile force to the slide, in a preferred embodiment the arm is arranged on the slide or on the actuating rod of the slide, the arm protruding from the housing and the arm running at least approximately perpendicular to the longitudinal direction of the sealing strip. This arm preferably also runs at least approximately perpendicular to the lowering direction of the sealing strip. The arm is preferably releasably attached to the slide. This arm preferably forms a stop surface for resting against a stationary or movable neighboring component of the building part.

Dank der Verwendung eines wie eine Fahne abstehenden Arms lässt sich der bewährte Absenkmechanismus gemäss CH 688 741 einsetzen, wobei der Schieber nun gezogen und nicht gestossen wird. Hierfür muss lediglich die Anordnung der Federn, insbesondere der Blattfedern in Bezug auf den vorstehenden Teil des Schiebers geändert werden; bzw. der Schieber steht in der erfindungsgemässen Dichtung am anderen Ende des Gehäuses vor als bei der CH 688 741 . Somit lässt sich eine bekannte Dichtung ohne allzu grosse bauliche Veränderungen für eine Vielzahl neuer Gebäudeteile, insbesondere in mehrteiligen Schiebesystemen, einsetzen. Die Erfindung ist jedoch nicht auf diese Veränderung der bekannten Absenkdichtung beschränkt sondern erstreckt sich auch auf andere veränderte bekannte Absenkmechanismen oder neuartige Absenkmechanismen, welche mit Ziehen aktivierbar sind.Thanks to the use of an arm that protrudes like a flag, the tried and tested lowering mechanism according to CH 688 741 insert with the slide now pulled and is not pushed. For this purpose, only the arrangement of the springs, in particular the leaf springs, has to be changed in relation to the protruding part of the slide; or the slide protrudes in the seal according to the invention at the other end of the housing than in the case of the CH 688 741 . In this way, a known seal can be used for a large number of new building parts, in particular in multi-part sliding systems, without too great structural changes. However, the invention is not limited to this modification of the known lowering seal but also extends to other modified known lowering mechanisms or novel lowering mechanisms which can be activated by pulling.

Das erfindungsgemässe Gebäudeteil weist eine derartige erfindungsgemässe Absenkdichtung auf, wobei das Gebäudeteil mindestens ein bewegliches Paneel aufweist, welches eine Gebäudeöffnung verschliesst und in bzw. an welchem die Absenkdichtung angeordnet ist. Erfindungsgemäss weist das Gebäudeteil ein dem beweglichen Paneel benachbartes Bauteil auf, welches bewirkt, dass der Schieber die erste Befestigungsstelle der Blattfeder in Richtung des vorstehenden Endes zieht.The building part according to the invention has such a lowering seal according to the invention, the building part having at least one movable panel which closes a building opening and in or on which the lowering seal is arranged. According to the invention, the building part has a component which is adjacent to the movable panel and which causes the slide to pull the first fastening point of the leaf spring in the direction of the protruding end.

Vorzugsweise weist das benachbarte Bauteil eine mindestens annähernd senkrecht zur Längsrichtung der Dichtleiste verlaufende Anschlagfläche für den Arm auf.The adjacent component preferably has a stop surface for the arm that runs at least approximately perpendicular to the longitudinal direction of the sealing strip.

Vorzugsweise ist mindestens eines der Bauteile ein zweites bewegliches Paneel.Preferably at least one of the components is a second movable panel.

Der Zug auf den Schieber kann an einem in Schliessrichtung der Tür rückseitigen Ende des Schiebers erfolgen. Der Zug kann in einer anderen Ausführungsform alternativ am in Schliessrichtung der Tür vorderen Ende des Schiebers erfolgen.
Das Gebäudeteil ist in bevorzugten Ausführungsformen eine einteilige Schiebetüre, ein mehrteiliges Schiebetürsystem, ein einteiliges Schiebefenster, ein mehrteiliges Schiebefenstersystem oder eine ein- oder mehrteilige Trennwand.The pull on the slide can take place at an end of the slide which is at the rear in the closing direction of the door. In another embodiment, the pull can alternatively take place at the front end of the slide in the closing direction of the door.
In preferred embodiments, the building part is a one-part sliding door, a multi-part sliding door system, a one-part sliding window, a multi-part sliding window system or a one-part or multi-part partition.

Weitere Ausführungsformen sind in den abhängigen Ansprüchen angegeben.Further embodiments are given in the dependent claims.

BESCHREIBUNG BEVORZUGTER AUSFÜHRUNGSFORMENDESCRIPTION OF PREFERRED EMBODIMENTS

In den Figuren 1 und 2 ist eine erfindungsgemässe Absenkdichtung in einer bevorzugten Anwendung dargestellt. Sie ist jedoch nicht auf diese Art der Anwendung beschränkt.In the Figures 1 and 2 a drop-down seal according to the invention is shown in a preferred application. However, it is not limited to this type of application.

Die Figuren 1 und 2 zeigen ein Gebäudeteil in Form einer mehrteiligen Trennwand oder einer mehrteiligen Schiebetür. Allfällige im Boden oder in der Decke eingelassene Führungsschienen sind nicht dargestellt. Die Trennwand bzw. das Schiebetürsystem weist mehrere Paneele T1, T2, T3 auf, welche nebeneinander angeordnet sind und relativ zueinander verschiebbar sind. Derartige Schiebemechanismen sind hinlänglich bekannt. In den Figuren ist ein dreiteiliges Paneelsystem dargestellt. Die erfindungsgemässe Dichtung lässt sich jedoch auch Systeme mit einem, zwei, vier oder mehr Paneelen einsetzen.the Figures 1 and 2 show a part of the building in the form of a multi-part partition or a multi-part sliding door. Any guide rails embedded in the floor or ceiling are not shown. The partition wall or the sliding door system has several panels T1, T2, T3 which are arranged next to one another and can be displaced relative to one another. Such sliding mechanisms are well known. A three-part panel system is shown in the figures. However, the seal according to the invention can also be used in systems with one, two, four or more panels.

Das Gebäudeteil weist ferner zumindest einen vorderen Rahmen R und einen hinteren Rahmen A auf, zwischen welchen die Paneele T1, T2, T3 gehalten sind. Der hintere Ramen ist vorzugsweise Teil einer Tasche oder Bahnhofs, in welchen die Paneele bei Nichtgebrauch eingefahren werden. Diese Tasche ist in den Figuren ebenfalls erkennbar. Das im geöffneten Zustand vorderste, erste Paneel T1 weist vorzugsweise einen Verriegelungsmechanismus auf, damit am vorderen Rahmen R fixiert werden kann. Der Verriegelungsmechanismus ist vorzugsweise ein Türschloss.The building part also has at least one front frame R and one rear frame A, between which the panels T1, T2, T3 are held. The rear frame is preferably part of a pocket or station, into which the panels are retracted when not in use. This pocket can also be seen in the figures. The foremost, first panel T1 in the open state preferably has a locking mechanism so that it can be fixed to the front frame R. The locking mechanism is preferably a door lock.

In jedem Paneel T1, T2, T3 ist eine Absenkdichtung D1, D2, D3 angeordnet. Sie sind vorzugsweise in entsprechende Nuten der Paneele eingelassen. Sie können aber an einer Stirnseite befestigt sein oder seitlich an den Paneelen angeordnet sein. Die Dichtungen D1, D2, D3 sind in diesem Beispiel jeweils mittels Befestigungswinkeln 5 auf mindestens einer, vorzugsweise an beiden Stirnseiten des Paneels T1 befestigt.A lowering seal D1, D2, D3 is arranged in each panel T1, T2, T3. They are preferably embedded in corresponding grooves in the panels. However, they can be attached to one end face or arranged on the side of the panels. In this example, the seals D1, D2, D3 are each fastened by means of fastening brackets 5 on at least one, preferably on both end faces of the panel T1.

Den Absenkdichtungen D1, D2, D3 steht jeweils an einem Ende ein Betätigungsstab oder -knopf 4 vor. Die vorderste erste Absenkdichtung D1 des ersten Paneels T1 weist in diesem Beispiel einen nach vorne, d.h. in Schliessrichtung, vorstehenden Betätigungsstab 4 auf. Die Betätigungsstäbe 4 der Absenkdichtungen D2, D3 der nachfolgenden Paneele T2, T3 stehen nach hinten, d.h. entgegen gesetzt zur Schliessrichtung, vor. An diesen nach hinten vorstehenden Betätigungsstäben 4 ist ein seitlich abstehender Arm 7 angeordnet bzw. er wirkt mit diesem zusammen. Er kann einstückig mit dem Betätigungsstab 4 ausgebildet sein. Vorzugsweise ist er jedoch an diesem aufgesteckt und/oder anderweitig befestigt. Der Arm 7 erstreckt sich zum jeweils in Schliessrichtung nachfolgenden Paneel T3 bzw. zum hinteren Rahmen A hin.The lowering seals D1, D2, D3 each have an actuating rod or button 4 protruding from one end. The foremost first lowering seal D1 of the first panel T1 has in this example an actuating rod 4 protruding forwards, i.e. in the closing direction. The actuating rods 4 of the lowering seals D2, D3 of the subsequent panels T2, T3 project to the rear, i.e. opposite to the closing direction. A laterally protruding arm 7 is arranged on these actuating rods 4 protruding to the rear, or it interacts with the latter. It can be designed in one piece with the actuating rod 4. However, it is preferably plugged onto this and / or fastened in some other way. The arm 7 extends towards the subsequent panel T3 in the closing direction or towards the rear frame A.

Die Paneele T1, T2, T3 sind mindestens im unteren Bereich, d.h. im Bereich dieser Absenkdichtungen D1, D2, D3, winklig ausgebildet. Vorzugsweise weisen sie einen L-förmigen Querschnitt auf, wie dies in den Figuren 1 und 2 dargestellt ist.The panels T1, T2, T3 are angled at least in the lower area, ie in the area of these lowering seals D1, D2, D3. They preferably have an L-shaped cross section, as shown in FIG Figures 1 and 2 is shown.

Das vorderste erste Paneel T1, welches beim Schliessen der Gebäudeöffnung zuerst bewegt wird, ist in diesem Beispiel anders ausgebildet als die anderen Paneele T2, T3. Auch ist ihre Absenkdichtung D1 nicht gleich ausgebildet wie die übrigen Absenkdichtungen D2, D3.The foremost first panel T1, which is moved first when the building opening is closed, is designed differently in this example than the other panels T2, T3. Its lowering seal D1 is also not designed in the same way as the other lowering seals D2, D3.

Im ersten Paneel T1 ist eine automatische mechanische Absenkdichtung bekannter Art angeordnet, welche beim Anstehen des Paneels T1 an den vorderen Rahmen R über einseitige Auslösung mit Druck betätigt wird. Dies erfolgt auf Grund des dem Gehäuse der Dichtung vorstehenden Betätigungsstabes 4, welcher mit dem Absenkmechanismus verbunden ist.An automatic mechanical lowering seal of a known type is arranged in the first panel T1, which is actuated with pressure when the panel T1 is in line with the front frame R via a one-sided release. This takes place on the basis of the actuating rod 4 protruding from the housing of the seal, which is connected to the lowering mechanism.

Die übrigen Paneele T2, T3 weisen mindestens im Bereich ihrer Dichtungen einen L-förmigen Querschnitt auf. Der so entstehende abstehende Winkel ist am vorderen Ende der jeweiligen Paneele T2, T3 angeordnet. D.h. er befindet sich beim Schliessen der Gebäudeöffnung vorne in Verschieberichtung des entsprechenden Paneels T2, T3. Der hintere Rahmen A weist in seinem in Schliessrichtung vorderen Bereich einen analogen Winkel auf.The remaining panels T2, T3 are L-shaped at least in the area of their seals Cross-section on. The protruding angle that is created in this way is arranged at the front end of the respective panels T2, T3. In other words, when the building opening is closed, it is at the front in the direction of displacement of the corresponding panel T2, T3. The rear frame A has an analogous angle in its front area in the closing direction.

Diese Winkel der Paneele T1, T2, T3 sowie des hinteren Rahmens A dienen als Anschlagfläche für den Arm 7, um die Absenkdichtung des beim Schliessen jeweils vorangehenden Paneels T2 zu aktivieren. Dies ist in Figur 2 gut erkennbar. Die Absenkdichtung wird somit durch Ziehen ausgelöst, indem der Arm 7 am Winkel B ansteht und somit der Betätigungsstab 4 noch weiter aus dem Gehäuse der Dichtung gezogen wird. Dadurch wird der Absenkmechanismus der Dichtung aktiviert und die Dichtleiste wird abgesenkt. Dies wird weiter unten noch näher erläutert.These angles of the panels T1, T2, T3 and of the rear frame A serve as a stop surface for the arm 7 in order to activate the lowering seal of the respective preceding panel T2 when it is closed. This is in Figure 2 good to see. The lowering seal is thus triggered by pulling, in that the arm 7 rests against the angle B and the actuating rod 4 is thus pulled even further out of the housing of the seal. This activates the lowering mechanism of the seal and the sealing strip is lowered. This is explained in more detail below.

Beim Öffnen des Gebäudeteils wird der Arm 7 vom Winkel B bzw. dem hinteren Rahmen A wieder freigegeben und die Zugkraft auf den Betätigungsstab 4 entfällt. Dadurch wird dieser federbelastet wieder weiter in das Gehäuse der Dichtung hineingezogen und der Absenkmechanismus hebt die Dichtleiste wieder an. Dies ist in Figur 1 gut erkennbar.When the part of the building is opened, the arm 7 is released again from the angle B or the rear frame A and the tensile force on the actuating rod 4 is eliminated. As a result, it is pulled further into the housing of the seal under spring load and the lowering mechanism raises the sealing strip again. This is in Figure 1 good to see.

Der Winkel des zweiten Paneels T2, welches dem ersten Paneel T1 nachfolgt, kann diese Funktion übernehmen, wenn das erste Paneel T1 dieselbe Absenkdichtung aufweist wie die übrigen, d.h. auch durch Ziehen ausgelöst wird. Da in diesem Beispiel die erste Absenkdichtung D1 jedoch auf bekannte Weise über Druck ausgelöst wird, hat der Winkel des zweiten Paneels T2 keine diesbezügliche Funktion. Vorzugsweise ist er jedoch mindestens aus ästhetischen Gründen vorhanden, damit die Trennwand oder das Schiebetürsystem ein einheitliches Erscheinungsbild aufweist.The angle of the second panel T2, which follows the first panel T1, can take over this function if the first panel T1 has the same lowering seal as the others, i.e. is also triggered by pulling. However, since in this example the first lowering seal D1 is triggered in a known manner by means of pressure, the angle of the second panel T2 has no function in this regard. However, it is preferably present at least for aesthetic reasons, so that the partition wall or the sliding door system has a uniform appearance.

Das erste Paneel T1 weist ebenfalls einen abstehenden Winkel auf. Dieser ist jedoch am hinteren Ende des Paneels T1 angeordnet, d.h. dem vorderen Rahmen R abgewandt. Auch dieser Winkel übernimmt keine Funktion beim Absenken der Dichtungen, ist jedoch ebenfalls vorzugsweise aus ästhetischen Gründen vorhanden.The first panel T1 also has a protruding angle. However, this is arranged at the rear end of the panel T1, i.e. facing away from the front frame R. This angle also has no function when the seals are lowered, but is also preferably present for aesthetic reasons.

Die Winkel der Paneele T1, T2, T3 im gegenseitigen Zusammenwirken wie auch die Arme in Kombination mit den benachbarten Winkeln dienen vorzugsweise zusätzlich als Mitnehmer und Anschläge beim Schliessen der Tür. Diese Funktion kann jedoch je nach Ausgestaltung des Schiebemechanismus des Gebäudeteils auch entfallen.The angles of the panels T1, T2, T3 in mutual cooperation as well as the arms in combination with the neighboring brackets, they also serve preferably as drivers and stops when closing the door. However, this function can also be omitted depending on the design of the sliding mechanism of the building part.

Sind die Absenkdichtungen an der unteren Stirnseite der Paneele angebracht, so können die Paneele auch ohne Winkel ausgebildet sein, wobei am freiliegenden Gehäuse der Dichtung ein entsprechender Winkel ausgebildet ist, welcher als Mitnehmer für den Arm der benachbarten Dichtung dient. Lediglich der hintere Rahmen A sollte ebenfalls über einen entsprechenden Anschlag für den Arm der letzten Dichtung verfügen.If the lowering seals are attached to the lower face of the panels, the panels can also be designed without an angle, with a corresponding angle being formed on the exposed housing of the seal, which serves as a driver for the arm of the adjacent seal. Only the rear frame A should also have a corresponding stop for the arm of the last seal.

In den Figuren 3 bis 11 ist eine bevorzugte Ausführungsform einer derartigen Absenkdichtung dargestellt. Die erfindungsgemässe Idee beschränkt sich jedoch nicht auf derartige Absenkmechanismen oder Dichtleisten.In the Figures 3 to 11 a preferred embodiment of such a drop-down seal is shown. However, the inventive idea is not limited to such lowering mechanisms or sealing strips.

Figur 3 zeigt eine erfindungsgemässe Absenkdichtung mit einem Gehäuse 1 und einer relativ zum Gehäuse anhebbaren und absenkbaren Dichtleiste 2, 3. Das Gehäuse 1 ist eine u-förmige nach unten offen ausbildete Profilschiene. Vorzugsweise besteht sie aus Aluminium. Es erstreckt sich vorzugsweise über annähernd die gesamte Länge des Paneels und somit der Dichtung. In Figur 3 ist ein Teil nicht dargestellt, damit das Innere der Dichtung besser erkennbar ist. Auch die Dichtleiste 2, 3, welche sich ebenfalls über die gesamte Länge erstreckt, ist nur teilweise dargestellt. Das Gehäuse 1 ist beispielsweise mittels Befestigungswinkeln 5 am Paneel befestigbar. Figure 3 shows a lowering seal according to the invention with a housing 1 and a sealing strip 2, 3 that can be raised and lowered relative to the housing. The housing 1 is a U-shaped profile rail that is open at the bottom. It is preferably made of aluminum. It preferably extends over approximately the entire length of the panel and thus the seal. In Figure 3 a part is not shown so that the interior of the seal can be seen better. The sealing strip 2, 3, which also extends over the entire length, is only partially shown. The housing 1 can be fastened to the panel by means of fastening brackets 5, for example.

Die Dichtleiste umfasst eine Trägerprofilschiene 3 und ein daran angeordnetes Dichtelement 2. Die Trägerprofilschiene 3 ist vorzugsweise ebenfalls aus Aluminium gefertigt. Das Dichtelement 2 besteht aus einem elastomeren Material und liegt im abgesenkten Zustand der Dichtleiste dichtend auf dem Gebäudeboden auf. Sie ist vorzugsweise aus Silikon, Gummi oder Kautschuk gefertigt. Sie kann einstückig oder mehrteilig ausgebildet sein. Vorzugsweise weist sie seitlich dichtende Flügel oder Schenkel auf.The sealing strip comprises a carrier profile rail 3 and a sealing element 2 arranged thereon. The carrier profile rail 3 is preferably also made of aluminum. The sealing element 2 consists of an elastomeric material and, in the lowered state of the sealing strip, rests on the building floor in a sealing manner. It is preferably made of silicone, rubber or rubber. It can be designed in one piece or in several parts. It preferably has wings or legs that seal laterally.

Im Gehäuse 1 ist ein Absenkmechanismus zum Absenken und Anheben der Dichtleiste 2, 3 angeordnet. Dieser Absenkmechanismus wird beim Schliessen des Gebäudeteils aktiviert, so dass er die Dichtleiste absenkt. Beim Öffnen des Gebäudeteils hebt er die Dichtleiste selbsttätig, vorzugsweise federbelastet, wieder an. Der Absenkmechanismus weist in diesem Ausführungsbeispiel mindestens eine, vorzugsweise zwei oder mehr Biege- oder Blattfedern 8 auf. Sind mehrere Blattfedern 8 vorhanden, so sind sie beabstandet zueinander in Längsrichtung der Dichtung hintereinander angeordnet.A lowering mechanism for lowering and raising the sealing strip 2, 3 is arranged in the housing 1. This lowering mechanism is activated when the part of the building is closed activated so that it lowers the sealing strip. When the part of the building is opened, it automatically lifts the sealing strip again, preferably in a spring-loaded manner. In this exemplary embodiment, the lowering mechanism has at least one, preferably two or more, flexible or leaf springs 8. If several leaf springs 8 are present, they are arranged one behind the other at a distance from one another in the longitudinal direction of the seal.

Im oberen Bereich des u-förmigen Gehäuses 1, also benachbart zu ihrem oberen Steg, verläuft eine Kraftübertragungsstange 6. Diese ist vorzugsweise als Flachstange ausgebildet und in einer entsprechenden Nut im Gehäuse 1 gehalten. Die Kraftübertragungsstange 6 ist in Längsrichtung des Gehäuses 1 relativ zu diesem verschiebbar. Das Gehäuse 1 weist vorzugsweise an den Innenseiten ihrer parallelen Schenkel vorstehende Absätze auf, auf welchem die Stange 6 aufliegt.In the upper region of the U-shaped housing 1, that is to say adjacent to its upper web, a force transmission rod 6 runs. This is preferably designed as a flat rod and held in a corresponding groove in the housing 1. The force transmission rod 6 is displaceable in the longitudinal direction of the housing 1 relative to the latter. The housing 1 preferably has protruding shoulders on the insides of its parallel legs, on which the rod 6 rests.

Die mindestens eine Blattfeder 8 ist an drei Orten in der Dichtung befestigt. Ein erstes Ende der Blattfeder 8 ist an einer ersten Befestigungsstelle am Kraftübertragungsstab 6 befestigt. Diese Befestigung ist starr. Dies ist in Figur 4 gut erkennbar. Ein mittlerer Bereich der Blattfeder 8 ist an der Dichtleiste, genauer an der Trägerprofilschiene 3 befestigt. Diese Befestigung ist vorzugsweise ortsfest, d.h. die Blattfedern können sich innerhalb der Befestigungsstelle in Längsrichtung der Dichtung nicht verschieben. Dies ist in Figur 5 dargestellt. An ihrem zweiten Ende ist die Blattfeder 8 am Gehäuse 1 befestigt. Diese Befestigung ist schwenkend, d.h. die Blattfeder 8 lässt sich relativ zum Gehäuse 1 schwenken. Dies ist in Figur 6 gut erkennbar. Weitere allfällig vorhandene Blattfedern sind analog befestigt.The at least one leaf spring 8 is fastened at three locations in the seal. A first end of the leaf spring 8 is fastened to a first fastening point on the force transmission rod 6. This attachment is rigid. This is in Figure 4 good to see. A central area of the leaf spring 8 is attached to the sealing strip, more precisely to the support profile rail 3. This fastening is preferably stationary, ie the leaf springs cannot move within the fastening point in the longitudinal direction of the seal. This is in Figure 5 shown. The leaf spring 8 is attached to the housing 1 at its second end. This fastening is pivoting, ie the leaf spring 8 can pivot relative to the housing 1. This is in Figure 6 good to see. Any other leaf springs that may be present are attached in the same way.

An einem hinteren Ende dieser Kraftübertragungsstange 6 ist ein Betätigungsstab 4 angeordnet. Stange 6 und Stab 4 können gemeinsam einstückig ausgebildet sein. Vorzugsweise ist der Stab 4 jedoch an der Stange 6 befestigt, z. B. angeschweisst. Der Stab 4 ist vorzugsweise als Gewindestab ausgebildet, so dass seine Länge wahlweise eingestellt werden kann. Dieser Stab 4 steht dem Gehäuse 1 der Dichtung einseitig vor. Dank des Gewindes lässt sich der Überstand des Stabes 4 den örtlichen Gegebenheiten des Gebäudes anpassen und die Dichtung lässt sich so optimal vor Ort einstellen.An actuating rod 4 is arranged at a rear end of this force transmission rod 6. Rod 6 and rod 4 can be designed together in one piece. Preferably, however, the rod 4 is attached to the rod 6, e.g. B. welded on. The rod 4 is preferably designed as a threaded rod so that its length can be adjusted as required. This rod 4 protrudes from the housing 1 of the seal on one side. Thanks to the thread, the protrusion of the rod 4 can be adapted to the local conditions of the building and the seal can thus be optimally adjusted on site.

Am vorstehenden Ende des Betätigungsstabs 4 ist ein Arm 7 befestigt. Auch dieser kann einstückig mit dem Stab 4 ausgebildet sein. Vorzugsweise ist er jedoch aufgesteckt, angeschraubt oder anderweitig befestigt. Der Arm 7 steht mindestens annähernd senkrecht vom Stab 4 und von der Längsrichtung der Dichtung ab. Dies ist in Figur 7 gut erkennbar. Vorzugsweise steht er auch senkrecht von der Längsfläche der Dichtung und somit von der Paneelfläche ab. Der Arm 7 ist vorzugsweise ein im Wesentlichen quaderförmiger Block. Er ist vorzugweise aus Kunststoff oder einem Metall, insbesondere Aluminium, gefertigt. Die Verbindung zwischen Arm 7 und Stab 4 ist vorzugsweise starr und steif, so dass eine Kraft, welche auf eine der Dichtung zugewandte Seitenfläche des Arms 7 wirkt, auf den Betätigungsstab 4 übertragbar ist und vom Betätigungsstab 4 als Zugkraft auf den mit diesem fest verbundenen Kraftübertragungsstab 6 übertragen wird.An arm 7 is attached to the protruding end of the operating rod 4. This can too be formed in one piece with the rod 4. However, it is preferably slipped on, screwed on or otherwise fastened. The arm 7 projects at least approximately perpendicularly from the rod 4 and from the longitudinal direction of the seal. This is in Figure 7 good to see. It preferably also projects perpendicularly from the longitudinal surface of the seal and thus from the panel surface. The arm 7 is preferably a substantially cuboid block. It is preferably made of plastic or a metal, in particular aluminum. The connection between arm 7 and rod 4 is preferably rigid and stiff, so that a force which acts on a side surface of arm 7 facing the seal can be transmitted to actuating rod 4 and from actuating rod 4 as a tensile force to the force transmission rod firmly connected to it 6 is transmitted.

In den Figuren 8 und 9 ist die Dichtung im angehobenen Zustand dargestellt. Es wirkt keine Kraft auf den Arm 7 und der Betätigungsstab 4 steht nur leicht dem Gehäuse 1 vor. In den Figuren 10 und 11 hingegen wirkt eine Kraft auf den Arm 7. Dadurch ist der Betätigungsstab 4 weiter aus dem Gehäuse 1 herausgezogen und zieht den Kraftübertragungsstab 6 mit sich. Aufgrund der drei Befestigungsstellen der mindestens einen Blattfeder 8 wird diese gebeugt und sie senkt die Dichtleiste ab.In the Figures 8 and 9 the seal is shown in the raised position. There is no force acting on the arm 7 and the actuating rod 4 protrudes only slightly from the housing 1. In the Figures 10 and 11 on the other hand, a force acts on the arm 7. As a result, the actuating rod 4 is pulled further out of the housing 1 and pulls the force transmission rod 6 with it. Because of the three fastening points of the at least one leaf spring 8, the latter is bent and it lowers the sealing strip.

In Figur 12 ist ein zweites erfindungsgemässes Ausführungsbeispiel einer mehrteiligen Schiebetür mit Absenkdichtung dargestellt. Die Absenkdichtung kann, muss aber nicht derjenigen gemäss den Figuren 3 bis 11 entsprechen.In Figure 12 is shown a second embodiment of the invention of a multi-part sliding door with lowering seal. The drop-down seal can, but does not have to be, the one according to the Figures 3 to 11 correspond.

Im Gegensatz zum Ausführungsbeispiel gemäss den Figuren 1 und 2 ist hier der Arm 7 am in Schliessrichtung der Schiebetür vorderen Ende des Betätigungsstabs 4 angeordnet bzw. er wirkt auf dessen vorderes Ende. Der Arm 7 ist dabei in die entgegengesetzte Richtung im Vergleich zum ersten Ausführungsbeispiel gerichtet. Die Paneele T1, T2, T3, selber sind gleich ausgebildet wie im ersten Ausführungsbeispiel, d.h. sie weisen einen L-förmigen Querschnitt auf mit einem langen, das Türblatt bildenden Schenkel, und einen kurzen Schenkel. Der kurze Schenkel ist zu dem beim Schliessen der Schiebetür nachfolgenden Paneel T2, T3 hin gerichtet.In contrast to the embodiment according to the Figures 1 and 2 Here the arm 7 is arranged at the front end of the actuating rod 4 in the closing direction of the sliding door or it acts on its front end. The arm 7 is directed in the opposite direction compared to the first embodiment. The panels T1, T2, T3 themselves are designed in the same way as in the first exemplary embodiment, ie they have an L-shaped cross section with a long limb, which forms the door leaf, and a short limb. The short leg is directed towards the panel T2, T3 which follows when the sliding door is closed.

Es sind nun jedoch die vorderen Anschläge C, d.h. die in Schliessrichtung vorderen Oberflächen der kurzen Schenkel, welche beim Schliessen der Schiebetür die hintere Fläche des Arms kontaktieren und diesen beim weiteren Schliessen mitnehmen. Dadurch wird der mit dem Arm 7 verbundene oder wirkverbundene Betätigungsstab 4 aus der Gehäuseschiene 1 herausgezogen und die Dichtung wird abgesenkt.However, it is now the front stops C, ie the front surfaces of the short legs in the closing direction, which are the rear ones when the sliding door is closed Contact the surface of the arm and take it with you when you close it further. As a result, the actuating rod 4 connected or operatively connected to the arm 7 is pulled out of the housing rail 1 and the seal is lowered.

Es versteht sich von selbst, dass der Absenkmechanismus der ersten Dichtung D1 des ersten Paneels T1, welches den anderen Paneelen T2, T3 beim Schliessen vorausgeht, gespiegelt zu den übrigen Dichtungen D2, D3 ausgebildet ist. D.h. die erste Dichtung D1 wird auf Druck ausgelöst. Wenn der Betätigungsstab 4 der ersten Dichtung D1 am vorderen Rahmen R ansteht, wird der Betätigungsstab 4 eingedrückt und die Dichtung wird wieder abgesenkt.It goes without saying that the lowering mechanism of the first seal D1 of the first panel T1, which precedes the other panels T2, T3 when they are closed, is designed to be mirrored to the other seals D2, D3. This means that the first seal D1 is released when pressure is applied. When the actuating rod 4 of the first seal D1 rests against the front frame R, the actuating rod 4 is pressed in and the seal is lowered again.

Die zweite Ausführungsform gemäss Figur 12 hat gegenüber der ersten Ausführungsform den Vorteil, dass die Arme 7 bei geöffneter oder teilweise geöffneter Tür frei zugänglich sind. Dies erleichtert das Einstellen der Dichtung bei der Montage und erleichtert auch ein allfälliges Auswechseln von Einzelteilen, insbesondere der Arme.The second embodiment according to Figure 12 has the advantage over the first embodiment that the arms 7 are freely accessible when the door is open or partially open. This makes it easier to adjust the seal during assembly and also makes it easier to replace individual parts, in particular the arms.

Die erste Ausführungsform gemäss den Figuren 1 und 2 hat hingegen den Vorteil, dass die Arme 7 weder bei offener noch bei geschlossener Tür sichtbar sind und dass somit das Erscheinungsbild der Schiebetür nicht beeinträchtigt wird.The first embodiment according to Figures 1 and 2 however, has the advantage that the arms 7 are not visible either when the door is open or when it is closed and that the appearance of the sliding door is therefore not impaired.

Beim Öffnen der Schiebetür werden in beiden Ausführungsbeispielen alle Dichtung angehoben, sobald der jeweilige Kontakt zwischen jeweiliger Anschlagfläche B, C und Arm 7 bzw. zwischen Rahmen und Betätigungsstab 4 aufgehoben ist.When the sliding door is opened, all seals are lifted in both exemplary embodiments as soon as the respective contact between the respective stop surface B, C and arm 7 or between the frame and the actuating rod 4 is canceled.

Die erfindungsgemässe Absenkdichtung ermöglicht eine einseitige Auslösung durch Ziehen, wobei die Dichtung platzsparend ausgebildet ist.
