Description

Schiebetür zum Verschließen einer Wandöffnung Sliding door to close a wall opening
Die Erfindung betrifft eine Schiebetür zum Verschließen einer Wandöffnung mit einem Türblatt und einer das Türblatt tragenden und an der Wand gehaltenen, Laufrollen und eine Lauf- und Führungsschiene aufweisenden Aufhängung, wobei die Lauf- und Führungsschiene für die Laufrollen eine derart verlaufende Laufbahn hat, daß das Türblatt bei seiner Bewegung in die Schließstellung parallel in Richtung der Wandöffnung versetzt und abgesenkt wird, wobei kraftspeichernde Elemente geladen werden.The invention relates to a sliding door for closing a wall opening with a door leaf and a supporting the door leaf and held on the wall, rollers and a track and guide rail suspension, the track and guide rail for the rollers has such a running track that the Door leaf is moved parallel to the wall opening and lowered during its movement into the closed position, with energy-storing elements being loaded.
Schiebetüren zum Verschließen von Wandöffnungen von Räumen, insbesondere Kühlräumen, sind in vielfacher Ausführung bekannt. Dabei kommt es häufig darauf an, daß das Türblatt die Wandöffnung nicht nur abdeckt, sondern sie auch möglichst dicht verschließt. Bei Kühlräumen ist dies von besonderer Bedeutung.Sliding doors for closing wall openings in rooms, in particular cold rooms, are known in many designs. It is often important that the door leaf not only covers the wall opening, but also closes it as tightly as possible. This is particularly important for cold rooms.
Dieses dichte Verschließen einer Wandöffnung wird mit einer bekannten Schiebetür der eingangs genannten Art (DE 26 16 495 AI) durch das Parallelversetzen und Absenken des Türblatts in der Schließstellung gewährleistet. Bei dieser räumlichen Verlagerung des Türblatts werden nämlich an den Türblatträndern und am Boden Dichtungen wirksam. Die räumliche Verlagerung des Türblatts in der Schließstellung wird durch eine besondere Geometrie der Aufhängung erreicht. Bei dieser Aufhängung besteht die an der Wand befestigte Laufschiene aus einem im wesentlichen U-förmigen Profil mit nach unten weisenden und 45° aufeinander zu abgeknickten Schenkelenden. Diese abgeknickten Schenkelenden bilden zwei Laufbahnen für eine Vielzahl von Laufrollen, die paarweise auf einem Rollenträger gelagert sind, der als T-Profil ausgebildet ist und das Türblatt trägt. Die der Türöffnung benachbarte Laufbahn weist im Bereich der Türöffnung für die Laufrolle Dellen auf. Gelangen die Laufrollen in diese Dellen, dann resultiert daraus der erwähnte Parallelversatz und die Absenkung des Türblatts .This tight closing of a wall opening is ensured with a known sliding door of the type mentioned (DE 26 16 495 AI) by the parallel displacement and lowering of the door leaf in the closed position. With this spatial displacement of the door leaf, seals are effective on the door leaf edges and on the floor. The spatial displacement of the door leaf in the closed position is achieved by a special geometry of the suspension. In this suspension, the running rail attached to the wall consists of an essentially U-shaped one Profile with leg ends pointing downwards and bent 45 ° towards each other. These bent leg ends form two raceways for a large number of rollers, which are mounted in pairs on a roller carrier which is designed as a T-profile and carries the door leaf. The track adjacent to the door opening has dents in the area of the door opening for the roller. If the rollers get into these dents, this results in the aforementioned parallel offset and the lowering of the door leaf.
Bei der bekannten Schiebetür ist weiterhin vorgesehen, daß die Schiebetür, wenn sie in ihre Schließstellung geschoben wird, einen horizontal angeordneten Federspeicher vorspannt, der sich beim Schließen der Tür gegen einen ortsfesten Anschlag vorspannt und die gespeicherte Energie beim Öffnungsvorgang freigibt. Diese Maßnahme ermöglicht es, daß die horizontale Öffnungsbewegung durch den vorgespannten Federspeicher unterstützt wird und somit für den Benutzer ein geringerer Kraftaufwand notwendig ist, um die Schiebetür aufzuziehen.In the known sliding door it is further provided that the sliding door, when pushed into its closed position, prestresses a horizontally arranged spring accumulator, which prestresses against a stationary stop when the door is closed and releases the stored energy during the opening process. This measure makes it possible for the horizontal opening movement to be supported by the prestressed spring accumulator, and therefore less effort is required for the user to pull open the sliding door.
Nachteilig bei dieser bekannten Schiebetür ist der konstruktive Aufwand für die aus Laufrollen und Lauf- und Führungsschiene bestehende Aufhängung. Ferner vermag der Federspeicher, der mit der Schließbewegung vorgespannt wird, diese Schließbewegung zu beeinträchtigen, so daß die horizontale Schließbewegung der Schiebetür nur unter Kraftaufwand oder mit Schwung erfolgen kann. Eine weitere, besondere Ausgestaltung einer Lauf- und Führungsschiene einer Schiebetür ist aus der DE 24 22 227 Bl bekannt. Diese Lauf- und Führungsschiene weist einen runden Querschnitt auf und ist als Hohl- oder Vollprofil ausgestaltet. Die Laufrollen sind, der Form der Lauf- und Führungsschiene angepaßt, als Keilrollen ausgeführt. Die runde Lauf- und Führungsschiene weist anstelle der oben genannten Dellen Einschnürungen in ihrem Querschnitt auf, die die Parallelversetzung und Absenkung des Türblatts bewirken, da in Schließstellung die Kontaktpunkte der Laufund Führungsschiene mit der Keilrolle durch den die Einschnürung verschmälerten Querschnitt der Lauf- und Führungsschiene tiefer in dem Keil der Keilrolle zum Mittelpunkt der Keilrolle hin liegen, so daß der Abstand der Mittelachse der Lauf- und Führungsschiene zu der Mittelachse der Keilrolle verringert wird, das Türblatt mit seiner Aufhängung also abgesenkt wird.A disadvantage of this known sliding door is the design effort for the suspension consisting of rollers and running and guide rails. Furthermore, the spring accumulator, which is biased with the closing movement, can impair this closing movement, so that the horizontal closing movement of the sliding door can only take place with effort or with momentum. Another, special embodiment of a running and guide rail of a sliding door is known from DE 24 22 227 B1. This running and guide rail has a round cross section and is designed as a hollow or solid profile. The rollers are designed as wedge rollers, adapted to the shape of the roller and guide rail. Instead of the dents mentioned above, the round running and guide rail has constrictions in its cross section, which bring about the parallel displacement and lowering of the door leaf, because in the closed position the contact points of the running and guide rail with the wedge roller are deeper due to the narrowing cross section of the running and guide rail lie in the wedge of the wedge roller towards the center of the wedge roller so that the distance of the central axis of the running and guide rail to the central axis of the wedge roller is reduced, so that the door leaf with its suspension is lowered.
Nachteilig bei den vorgenannten Schiebetüren ist, daß das gesamte Gewicht der Schiebetür im abgesenkten Zustand durch die Lauf- und Führungsschiene getragen werden muß, die an dieser Stelle bereits durch eine Einschnürung in ihrem Querschnitt geschwächt ist . Dies führt zu einer großen Belastung der Lauf- und Führungsschiene, die dazu führt, daß derartige Lauf- und Führungsschienen dementsprechend robust konstruiert werden müssen. Zusätzlich besteht für den Benutzer die Schwierigkeit, die schwere Schiebetür aus der abgesenkten Schließstellung heraus zu öffnen. Der Benutzer muß die gesamte Kraft aufbringen, die erforderlich ist, um die Tür aus ihrer abgesenkten Schließstellung heraus nach oben zu bewegen. Der Erfindung liegt die Aufgabe zugrunde, eine Schiebetür zum Verschließen einer Wandöffnung zu schaffen, die bei einem geringen konstruktiven Aufwand das Öffnen mit relativ wenig Kraft ermöglicht.A disadvantage of the aforementioned sliding doors is that the entire weight of the sliding door in the lowered state must be borne by the running and guide rail, which at this point is already weakened in its cross section by a constriction. This leads to a large load on the running and guide rails, which leads to the fact that such running and guide rails must be constructed accordingly robust. In addition, there is the difficulty for the user to open the heavy sliding door from the lowered closed position. The user must apply all of the force required to move the door up from its lowered closed position. The invention has for its object to provide a sliding door for closing a wall opening that allows opening with relatively little effort with little design effort.
Diese Aufgabe wird erfindungsgemäß mit einer Schiebetür der eingangs genannten Art dadurch gelöst, daß mindestens eine in Schließstellung mit den Laufrollen in Kontakt stehende, parallel zu der Lauf- und Führungsschiene verlaufende Stützschiene vorgesehen ist, daß die Stützschiene über die kraftspeichernden Elemente an der Wand abgestützt ist, und daß die Stützschiene relativ zur Lauf- und Führungsschiene in Richtung des Parallelversatzes und/oder der Absenkung des Türblatts bewegbar ist .This object is achieved with a sliding door of the type mentioned in that at least one in the closed position in contact with the rollers in contact, running parallel to the running and guide rail support rail is provided that the support rail is supported on the energy-storing elements on the wall , and that the support rail is movable relative to the running and guide rail in the direction of the parallel offset and / or the lowering of the door leaf.
Die erfindungsgemäß vorgesehene Stützschiene stützt die Laufrollen der Schiebetür, wenn diese in die Schließstellung überführt und dadurch abgesenkt werden. Durch die Absenkung der Laufrollen wird die Stützschiene nach unten beziehungsweise in die Richtung des Parallelversatzes des Türblatts gedrückt, wodurch die kraftspeichernden Elemente, durch die die Stützschiene mit der Wand verbunden ist, aufgeladen werden. Die Kraftspeicher wirken entgegen dem Parallelversatz und/oder der Absenkung der Tür und unterstützen demnach die Öffnungsbewegung der Tür aus der Schließstellung heraus, indem sie sich in Richtung des Rückversatzes und der Anhebung des Türblatts entladen. Im Vergleich zu dem vorbekannten Federspeicher haben die erfindungsgemäß vorgesehenen kraftspeichernden Elemente den Vorteil, daß sie durch das Eigengewicht des sich absenkenden Türblatts geladen werden und die horizontale Schließbewegung der Tür nicht behindern. Für den Benutzer ist es somit weiterhin einfach möglich, die Schiebetür zuzuziehen.The support rail provided according to the invention supports the rollers of the sliding door when these are transferred to the closed position and thereby lowered. By lowering the rollers, the support rail is pressed downwards or in the direction of the parallel offset of the door leaf, as a result of which the energy-storing elements by which the support rail is connected to the wall are charged. The energy accumulators counteract the parallel offset and / or the lowering of the door and therefore support the opening movement of the door from the closed position by discharging in the direction of the back offset and the lifting of the door leaf. Compared to the known spring-loaded device, the force-storing elements provided according to the invention have the advantage that they are loaded by the weight of the lowering door leaf and do not hinder the horizontal closing movement of the door. It is therefore still easy for the user to pull the sliding door shut.
Nach einer Ausgestaltung der Erfindung ist vorgesehen, daß die Laufrollen Keilrollen sind und die Lauf- und Führungsschiene ortsgleich mit den jeweiligen Laufrollen in Schließstellung eine einseitige Einschnürung aufweist, die die Parallelversetzung und Absenkung des Türblatts bewirkt. Diese Ausgestaltung der Laufrollen und der Lauf- und Führungsschiene führt zu einer besonders guten und konstruktiv einfachen Führung der Schiebetür auf der Laufund Führungsschiene, da sich die Keilrolle mit ihren trapezförmigen Schenkeln auf der Lauf- und Führungsschiene abstützt und eine seitliche Relativbewegung der Keilrolle zu der Lauf- und Führungsrolle wirksam verhindert.According to one embodiment of the invention, it is provided that the rollers are wedge rollers and that the running and guide rails have a one-sided constriction in the closed position at the same location as the respective rollers, which causes the door leaf to be offset and lowered in parallel. This design of the rollers and the track and guide rail leads to a particularly good and structurally simple guidance of the sliding door on the track and guide rail, since the wedge roller with its trapezoidal legs is supported on the track and guide rail and a lateral relative movement of the wedge roller to the barrel - and leadership role effectively prevented.
Die Lauf- und Führungsschiene kann dabei prismenförmig ausgeführt sein, wobei sie bei dieser Ausgestaltung beispielsweise in Form eines Dreiecks in die keilförmige Nut der Keilrolle eingreift.The running and guide rail can be designed in the form of a prism, with this embodiment engaging, for example in the form of a triangle, in the wedge-shaped groove of the wedge roller.
Alternativ ist es jedoch auch denkbar, die Lauf- und Führungsschiene aus einem der Form der Keilrolle angepaßten, runden Hohl- und/oder Vollprofil herzustellen. Die Verwendung eines runden Hohl- und/oder Vollprofils bringt dabei einen herstellungstechnischen Vorteil, da es im Unterschied zu der prismenförmigen Lauf- und Führungsschiene lediglich mit der Einschnürung versehen werden muß und nicht, wie das bei der prismenförmigen Laufund Führungsschiene notwendig ist, als solches mit mehreren Herstellungsschritten hergestellt werden muß.Alternatively, however, it is also conceivable to produce the running and guide rail from a round hollow and / or solid profile adapted to the shape of the wedge roller. The use of a round hollow and / or solid profile brings a manufacturing advantage because it in contrast to the prism-shaped running and guiding rail, it only has to be provided with the constriction and not, as is necessary in the case of the prism-shaped running and guiding rail, as such has to be produced with several manufacturing steps.
Um eine gute Rückstellwirkung durch die kraftspeichernden Elemente über die Stützschiene auf die Laufrollen übertragen zu können, hat es sich als zweckmäßig erwiesen, für jede Laufrolle eine Stützschiene vorzusehen, deren Position in der Länge parallel zur Lauf- und Führungsschiene im wesentlichen der der Einschnürung entspricht. Bei dieser Ausgestaltung ist lediglich auf Höhe der jeweiligen Einschnürung eine kurze Stützschiene für die jeweilige Laufrolle vorgesehen, die durch das Absenken der Laufrolle niedergedrückt wird und dadurch die kraftspeichernden Elemente auflädt und die beim Öffnungsvorgang der Schiebetür auf die jeweilige Laufrolle eine das Anheben und das Rückversetzen der Tür unterstützende Kraft ausübt.In order to be able to transfer a good restoring effect through the force-storing elements via the support rail to the rollers, it has proven to be expedient to provide a support rail for each roller, the length of which parallel to the roller and guide rail essentially corresponds to that of the constriction. In this embodiment, a short support rail for the respective roller is provided only at the level of the respective constriction, which is depressed by the lowering of the roller and thereby charges the energy-storing elements and which, when the sliding door is opened, is lifted and reset on the respective roller Door supporting force.
Besonders zweckmäßig werden die kraftspeichernden Elemente als Federn ausgestaltet. Hierfür können kostengünstige, in Großserien hergestellte Spiralfedern oder ähnliche verwendet werden.The energy-storing elements are particularly expediently designed as springs. Inexpensive, mass-produced spiral springs or the like can be used for this.
Alternativ ist es auch denkbar, die kraftspeichernden Elemente und die Stützschiene in einem Bauteil, nämlich einer mindestens einlagigen Blattfeder, zu vereinen. Dies vereinfacht den Aufbau der erfindungsgemäßen Schiebetür. Im folgenden wird die Erfindung anhand einer lediglich Ausführungsbeispiele darstellenden Zeichnung näher erläutert. Im einzelnen zeigen:Alternatively, it is also conceivable to combine the energy-storing elements and the support rail in one component, namely an at least single-layer leaf spring. This simplifies the construction of the sliding door according to the invention. The invention is explained in more detail below with reference to a drawing that shows exemplary embodiments only. In detail show:
Figur 1 zwei Laufrollen und einen Abschnitt der Laufund Führungsschiene eines ersten Ausführungsbeispiels der erfindungsgemäßen Schiebetür in einer Seitenansicht,FIG. 1 shows two rollers and a section of the running and guide rail of a first exemplary embodiment of the sliding door according to the invention in a side view,

Schiebetür in einer geschnittenen Darstellung.Sliding door in a sectional view.
Ein Türblatt 1 der in Figur 1 dargestellten Schiebetür ist über bügeiförmige Halter 2 mit den als Keilrollen ausgestalteten Laufrollen 3,4 verbunden. Die Laufrollen 3,4 stützen sich mit ihren keilförmigen Schenkeln auf der Laufund Führungsschiene 5 ab. Die Lauf- und Führungsschiene 5 ist, wie in der Figur 2 ersichtlich, über eine Halterung 6 mit der die von der Türblatt 1 in der Schließstellung zu verdeckenden Wandoffnung umgebenen Wand 7 verbunden. Die Lauf- und Führungsschiene 5 weist an den der Schließstellung entsprechenden Positionen der Laufrollen 3,4 jeweils eine Einschnürung 13 auf, bei der sich der runde Querschnitt der Lauf- und Führungsschiene 5 auf einen halbkreisförmigen Querschnitt reduziert.A door leaf 1 of the sliding door shown in FIG. 1 is connected to the rollers 3, 4 designed as wedge rollers via bow-shaped holders 2. The rollers 3, 4 are supported with their wedge-shaped legs on the running and guide rail 5. As can be seen in FIG. 2, the running and guide rail 5 is connected via a holder 6 to the wall 7 which is surrounded by the wall opening to be covered by the door leaf 1 in the closed position. The running and guide rail 5 each have a constriction 13 at the positions of the running rollers 3, 4 corresponding to the closed position, in which the round cross section of the running and guide rail 5 is reduced to a semicircular cross section.
Alternativ ist es jedoch auch denkbar, daß für beide Rollen eine durchgehende Einschnürung vorgesehen ist. Die Länge der Einschnürung entlang der Lauf- und Führungsschiene 5 entspricht dem Abstand der als Doppelrollen zusammengefaßten Rollen 3,4 zueinander, so daß diese beiden Laufrollen 3,4 in der Schließstellung der Schiebetür in einer gemeinsamen Einschnürung sitzen.Alternatively, however, it is also conceivable that a continuous constriction is provided for both roles. The length of the constriction along the running and guide rail 5 corresponds to the distance between the rollers 3, 4 combined as double rollers, so that these two rollers 3, 4 are seated in a common constriction in the closed position of the sliding door.
Parallel zu der Lauf- und Führungsschiene 5 ist ortsgleich mit der jeweiligen Laufrolle 3,4 in Schließstellung eine Stützschiene 8 vorgesehen. Diese Stützschiene 8 ist mittels als Federn ausgestalteten kraftspeichernden Elementen 9 mit einer Halterung 10 verbunden, die an der Wand 7 angebracht ist und somit die Stützschiene 8 an der Wand abstützt.A support rail 8 is provided parallel to the running and guide rail 5 in the same position as the respective running roller 3, 4 in the closed position. This support rail 8 is connected by means of force-storing elements 9 designed as springs to a holder 10 which is attached to the wall 7 and thus supports the support rail 8 on the wall.
Zwischen dem Türblatt 1 und der die von dem Türblatt 1 zu verschließenden Wandöffnung umgebenen Wand 7 ist eine an dem Türblatt 1 befestigte Dichtung 11 vorgesehen.A seal 11 fastened to the door leaf 1 is provided between the door leaf 1 and the wall 7 surrounding the wall opening to be closed by the door leaf 1.
Das Türblatt 1 wird von mindestens zwei Rollenpaaren mit Laufrollen 3,4 auf der Lauf- und Führungsschiene 5 getragen. Ein Paar ist näher zur Vorderseite des Türblatts 1 angeordnet, während das mindestens eine weitere Paar näher zum hinteren Ende des Türblatts 1 angeordnet ist. Die Paare sind dabei derart angeordnet, daß das Türblatt 1 lediglich in der Schließstellung in eine abgesenkte, parallelversetzte Lage gerät. Dies wird durch die relative Lage der Einschnürungen 13 und der Rollenpaare, sowie den Abstand der Rollen 3,4 zueinander in dem jeweiligen Rollenpaar erreicht.The door leaf 1 is carried on the running and guide rail 5 by at least two pairs of rollers with rollers 3, 4. A pair is arranged closer to the front of the door leaf 1, while the at least one further pair is arranged closer to the rear end of the door leaf 1. The pairs are arranged such that the door leaf 1 only in the closed position in a lowered, parallel offset position. This is achieved by the relative position of the constrictions 13 and the pairs of rollers, and the distance of the rollers 3, 4 from one another in the respective pair of rollers.
Der Abstand der Einschnürungen 13 für das dem hinteren Ende des Türblatts 1 zugeordnete Rollenpaar zueinander ist kleiner, als der Abstand der Laufrollen 3,4 des vorderen Rollenpaars zueinander. Dadurch wird erreicht, daß die Laufrollen des vorderen Rollenpaars nicht gleichzeitig in die Einschnürungen des hinteren Rollenpaars eingreifen können, was eine ungewünschte Absenkung der vorderen Seite des Türblatts 1 zur Folge hätte.The distance between the constrictions 13 for the roller pair assigned to the rear end of the door leaf 1 is smaller than the distance between the rollers 3, 4 of the front roller pair to one another. It is thereby achieved that the rollers of the front roller pair cannot simultaneously engage in the constrictions of the rear roller pair, which would result in an undesired lowering of the front side of the door leaf 1.
Vor Erreichen der Schließstellung ist immer mindestens eine Rolle eines Rollenpaares tragend wirksam im Bereich des Vollprofils.Before reaching the closed position, at least one role of a pair of rollers is always effective in the area of the full profile.
Das in Fig. 3 darstellte weitere Ausführungsbeispiel der erfindungsgemäßen Schiebetür unterscheidet sich von dem in den Fig. 1 und 2 dargestellten lediglich durch die Ausgestaltung der elastischen Elemente und der Stützschiene, so daß zur Vermeidung von Wiederholungen unter Beibehaltung gleicher Bezugszeichen für gleiche Bauteile lediglich die in der Fig. 3 unterschiedlichen Bauteile beschrieben werden.The other embodiment of the sliding door according to the invention shown in Fig. 3 differs from that shown in Figs. 1 and 2 only by the design of the elastic elements and the support rail, so that to avoid repetitions while maintaining the same reference numerals for the same components only in 3 different components are described.
Bei dem zweiten Ausführungsbeispiel ist parallel zu der Lauf- und Führungsschiene 5 ortsgleich mit der jeweiligen Laufrolle 3,4 in Schließstellung eine Blattfeder 14 vorgesehen. Diese Blattfeder 14 ist an einem Ende an der der Wand 7 angebrachten Halterung 10 befestigt, so daß sie freitragend an der Wand abgestützt ist.In the second exemplary embodiment, a leaf spring 14 is parallel to the running and guide rail 5 in the same position as the respective running roller 3, 4 in the closed position intended. This leaf spring 14 is attached at one end to the bracket 10 attached to the wall 7, so that it is supported in a self-supporting manner on the wall.
In Öffnungsstellung des Türblatts 1 befinden sich die Laufrollen 3,4 im Eingriff mit dem Vollprofil der Lauf- und Führungsschiene 5. Durch die keilförmige Nut 12 der Laufrollen 3,4 liegen die Kontaktpunkte der keilförmigen Schenkel der Laufrolle 3,4 mit der Lauf- und Führungsschiene 5 relativ weit am breiten, äußeren Ende der keilförmigen Nut 12.In the open position of the door leaf 1, the rollers 3, 4 are in engagement with the full profile of the track and guide rail 5. The wedge-shaped groove 12 of the rollers 3, 4 are the contact points of the wedge-shaped legs of the roller 3, 4 with the roller and Guide rail 5 relatively far at the wide, outer end of the wedge-shaped groove 12.
Wird das Türblatt 1 in die Schließstellung gebracht, so wird sie horizontal in der Lauf- und Führungsschiene 5 bewegt. Während dieser Bewegung ist es möglich, daß eine der Laufrollen 3,4 bereits in eine erste Einschnürung der Lauf- und Führungsschiene 5 gerät. Da jedoch die Rasterung der Lauf- und Führungsschiene 5 derart gewählt ist, daß erst in der endgültigen Schließstellung alle Rollen in eine Einschnürung eingreifen, wird während der ganzen Bewegung des Türblatts 1 von der Öffnungsstellung in die Schließstellung das Türblatt 1 wenigstens durch eine der jeweils zu Doppelpaaren zusammengefaßten Laufrollen 3,4 getragen, die sich noch im Kontakt mit dem Vollprofil befindet .If the door leaf 1 is brought into the closed position, it is moved horizontally in the running and guide rail 5. During this movement it is possible that one of the rollers 3, 4 already gets into a first constriction of the running and guide rail 5. However, since the grid of the running and guide rail 5 is selected such that all the rollers engage in a constriction only in the final closed position, the door leaf 1 becomes at least by one of the each during the entire movement of the door leaf 1 from the open position to the closed position Double pairs of combined rollers 3.4 carried, which is still in contact with the full profile.
Bei Erreichen der Schließstellung greifen nunmehr die Laufrollen 3,4 beider Rollenpaare in ihre jeweiligen Einschnürung 13 der Lauf- und Führungsschiene 5 ein. Dadurch wird das Türblatt 1 parallel in Richtung auf die Wandöffnung versetzt und abgesenkt. Dies wird dadurch bewirkt, daß durch die Änderung des Profils der Lauf- und Führungsschiene 5 zu einem Halbkreisprofil der Kontaktpunkt zwischen der Keilrolle 3,4 und der Lauf- und Führungsschiene 5 nunmehr nicht mehr am breiten, äußeren Ende der keilförmigen Nut 12 liegt, sondern weiter innen in einem schmaleren Bereich der keilförmigen Nut.When the closed position is reached, the rollers 3, 4 of both pairs of rollers now engage in their respective constrictions 13 in the running and guide rail 5. As a result, the door leaf 1 is offset and lowered parallel to the wall opening. This will do so causes that by changing the profile of the running and guide rail 5 to a semicircular profile, the contact point between the wedge roller 3, 4 and the running and guide rail 5 is no longer at the wide, outer end of the wedge-shaped groove 12, but further inside a narrower area of the wedge-shaped groove.
In der für die Schließstellung vorgesehenen relativen Position der Laufrollen 3,4 entlang der Lauf- und Führungsschiene 5 sind die Stützschienen 8, bzw. die Blattfedern 14 angeordnet. Die Laufrollen 3,4 stützen sich auf den Stützschienen 8, bzw. den Blattfedern 14 ab und drücken diese durch ihre Absenkbewegung nach unten, so daß die die Stützschienen 8 tragenden Federn 9 komprimiert und dadurch geladen werden, bzw. die Blattfedern 14 durchgebogen und dadurch geladen werden. Durch die geladenen Federn 9, bzw. die geladene Blattfeder 14 wird eine Rückstellkraft über die Stützschiene 8, bzw. direkt auf die Rollen 3,4 übertragen, die entgegen der Absenkung des Türblatts 1 in der Schließstellung wirkt. Diese Rückstellkraft führt dazu, daß das Türblatt 1 beim ÖffnungsVorgang durch den Benutzer einfacher aus der abgesenkten Schließposition herausbefordert werden kann.In the relative position of the rollers 3, 4 along the running and guide rail 5 provided for the closed position, the support rails 8 or the leaf springs 14 are arranged. The rollers 3, 4 are supported on the support rails 8 or the leaf springs 14 and press them downward by their lowering movement, so that the springs 9 carrying the support rails 8 are compressed and thereby loaded, or the leaf springs 14 are bent and thereby Loading. The loaded springs 9 or the loaded leaf spring 14 transmit a restoring force via the support rail 8 or directly to the rollers 3, 4, which acts against the lowering of the door leaf 1 in the closed position. This restoring force means that the door leaf 1 can be more easily challenged from the lowered closed position by the user during the opening process.
Durch die Absenkbewegung des Türblatts 1 und die damit verbundene Parallelversetzung des Türblatts 1 in Richtung auf die Wandöffnung hin, wird die Dichtung 11 zusammengedrückt und dichtet damit die Wandöffnung ab. Due to the lowering movement of the door leaf 1 and the associated parallel displacement of the door leaf 1 in the direction of the wall opening, the seal 11 is compressed and thus seals the wall opening.
