Description

Die vorliegende Erfindung betrifft eine Schiebetür für Fahrzeuge, welche mindestens einen Türflügel mit einer Hauptschließkante und eine dieser gegenüberliegenden Nebenschließkante umfasst.The present invention relates to a sliding door for vehicles, which comprises at least one door leaf with a main closing edge and a side closing edge opposite thereto.

Schiebetüren, insbesondere Taschenschiebetüren finden in Fahrzeugen, besonders in Schienenfahrzeugen wie Zügen, also zum Beispiel in Untergrund- oder Überlandbahnen, eine weit verbreitete Anwendung. Seit dem ersten Einsatz derartiger Schiebetüren besteht eine Problematik darin, dass sich selbige nur sehr schwer gegenüber einem Luftaustausch zwischen dem sich hinter der Schiebetür befindenden Innenraum des Fahrzeugs und der sich vor der Schiebetür befindenden äußeren Umgebung abdichten lassen. Je undichter eine Schiebetür jedoch ist, desto schlechter sind ihre akustischen und aerodynamischen Eigenschaften. Insbesondere bei innen liegenden Führungsschienen ist die beschriebene Problematik von Relevanz, da gerade die Stirnseiten solcher Führungsschienen im geschlossenen Zustand der Schiebetür oftmals Undichtigkeiten aufweisen.Sliding doors, in particular pocket sliding doors are widely used in vehicles, especially in rail vehicles such as trains, for example, in underground or overland railways. Since the first use of such sliding doors, there is a problem in that they are very difficult to seal against an air exchange between the interior of the vehicle located behind the sliding door and the external environment located in front of the sliding door. However, the more leaky a sliding door is, the worse are its acoustic and aerodynamic properties. Particularly in the case of internal guide rails, the problem described is of relevance, since the end faces of such guide rails often have leaks in the closed state of the sliding door.

Der Stand der Technik kennt zur Lösung dieses Problems bereits einige zum Beispiel auf aufblasbaren, umlaufenden Dichtungen basierende Ansätze, welche aber regelmäßig sehr kostenintensiv sind.The prior art knows to solve this problem already some, for example, on inflatable, circumferential seals based approaches, but which are usually very expensive.

Die dem Oberbegriff entsprechende Druckschrift KR 2009 0059546 A offenbart eine Schiebetür mit einem Dichtungselement, welches sich entlang der Nebenschließkante des Türflügels erstreckt. Der Türflügel läuft in einer Wand. Das Dichtungselement schließt den in der Wand befindlichen Hohlraum bei geschlossener Schiebetür dicht ab.The preamble corresponding document KR 2009 0059546 A discloses a sliding door having a sealing element which extends along the minor closing edge of the door leaf. The door is running in a wall. The sealing element closes off the cavity in the wall with the sliding door closed tightly.

Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, eine im Vergleich zum Stand der Technik einfachere, alternative Lösung zur Optimierung der akustischen beziehungsweise aerodynamischen Eigenschaften einer Schiebetür bereitzustellen.The present invention is therefore based on the object, a simpler compared to the prior art, to provide an alternative solution for optimizing the acoustic or aerodynamic properties of a sliding door.

Erfindungsgemäß wird eine Schiebetür für mit den technischen Merkmalen des Anspruchs 1 zur Verfügung gestellt, welche mindestens einen Türflügel umfasst, durch welchen die Schiebetür öffenbar und verschließbar ist und welcher eine Hauptschließkante und eine dieser gegenüber liegende Nebenschließkante aufweist. Des Weiteren umfasst die Schiebetür eine Führungsschiene zur Führung des mindestens einen Türflügels, welche mindestens eine Stirnseite und zwei Längsseiten aufweist. Erfindungsgemäß umfasst die Schiebetür ein Dichtungselement, welches sich entlang zumindest eines Teils der Nebenschließkante des Türflügels erstreckt, wobei sich das Dichtungselement in Richtung der Führungsschiene über ein erstes Ende der Nebenschließkante hinaus erstreckt und derart ausgebildet ist, dass es in einem geschlossenen Zustand der Schiebetür die Führungsschiene im Bereich ihrer mindestens einen Stirnseite im Wesentlichen luftdicht abdichtet, wobei das Dichtungselement im geschlossenen Zustand der Schiebetür auf der Stirnseite der Führungsschiene aufliegt. Dadurch kann die Führungsschiene und der Bereich an der Stirnseite der Führungsschiene hermetisch besonders gut und fest abgedichtet werden.According to the invention, a sliding door is provided for with the technical features of claim 1, which comprises at least one door leaf through which the sliding door can be opened and closed and which has a main closing edge and a side closing edge opposite thereto. Furthermore, the sliding door comprises a guide rail for guiding the at least one door leaf, which has at least one end face and two longitudinal sides. According to the invention, the sliding door comprises a sealing element which extends along at least part of the secondary closing edge of the door leaf, wherein the sealing element extends in the direction of the guide rail beyond a first end of the secondary closing edge and is designed such that it is the guide rail in a closed state of the sliding door seals in the region of at least one end side substantially airtight, wherein the sealing element rests in the closed state of the sliding door on the end face of the guide rail. As a result, the guide rail and the area on the front side of the guide rail hermetically sealed particularly well and tight.

Der Vorteil einer solchen Schiebetür liegt in der einfachen Abdichtung des stirnseitigen, offenen Endes der Führungsschiene der Schiebetür. Dabei beruht die Abdichtung auf einem Topf-Deckel-Prinzip. Das an der Nebenschließkante angebrachte Dichtungselement, welches beispielsweise als Dichtgummi ausgeführt sein kann, bildet im geschlossenen Zustand der Schiebetür einen Deckel, welcher die Stirnseite der Führungsschiene verschließt beziehungsweise hermetisch abdichtet und somit einen Luftaustausch durch die offenen Enden der Führungsschiene verhindert. Bei einer derart ausgeführten Schiebetür derartigen Ausführung der Schiebetür die akustischen beziehungsweise aerodynamischen Eigenschaften der Tür verbessert.The advantage of such a sliding door lies in the simple sealing of the frontal, open end of the guide rail of the sliding door. The seal is based on a pot-lid principle. The attached to the minor closing edge sealing element, which may be embodied for example as a sealing rubber, forms in the closed state of the sliding door a lid which closes the end face of the guide rail or hermetically seals and thus prevents air exchange through the open ends of the guide rail. In such a sliding door such embodiment of the sliding door improves the acoustic or aerodynamic properties of the door.

Das Dichtungselement ist demnach so angeordnet und ausgebildet, dass es den den Türflügel führenden Teil der Führungsschiene, die eigentliche Führung, luftdicht abdichtet. Mit anderen Worten ist das Dichtungselement so ausgebildet, dass es sowohl die Nebenschließkante des Türflügels als auch die Führungsschiene derart kontaktiert, dass im geschlossenen Zustand der Schiebetür der Bereich zwischen Türflügel und Führungsschiene an der Nebenschließkante luftdicht abgedichtet bzw. vom Dichtungselement vollständig verschlossen wird.Accordingly, the sealing element is arranged and designed such that it seals the part of the guide rail guiding the door leaf, the actual guide, airtight. In other words, the sealing element is designed such that it contacts both the secondary closing edge of the door leaf and the guide rail such that in the closed state of the sliding door, the area between the door leaf and the guide rail is hermetically sealed at the secondary closing edge or completely closed by the sealing element.

Besonders bevorzugt dichtet das Dichtungselement in einem geschlossenen Zustand der Schiebetür die Führungsschiene im Bereich ihrer mindestens einen Stirnseite luftdicht ab. In einer derartigen Ausführungsform sind die aerodynamischen und akustischen Eigenschaften der Schiebetür noch weiter verbessert. Somit wird eine Geräuschentwicklung im Bereich der Stirnseite der Führungsschiene unterbunden beziehungsweise reduziert. Das Dichtungselement fungiert beziehungsweise bildet somit im Bereich der Stirnseite der Führungsschiene ein dichtendes Schott.Particularly preferably, the sealing element in a closed state of the sliding door seals the guide rail in the region of its at least one end face airtight. In such an embodiment, the aerodynamic and acoustic properties of the sliding door are even further improved. Thus, a noise in the region of the end face of the guide rail is prevented or reduced. The sealing element thus acts or forms a sealing bulkhead in the region of the end face of the guide rail.

Bevorzugt handelt es sich bei der Hauptschließkante um die im geöffneten Zustand der Schiebetür der Schiebetüröffnung zugewandte Kante des Türflügels. Dementsprechend handelt es sich bei der Nebenschließkante bevorzugt um die im geöffneten Zustand der Schiebetür von der Schiebetüröffnung abgewandte Kante des Türflügels.The main closing edge is preferably the edge of the door leaf facing the sliding door opening when the sliding door is open. Accordingly, the secondary closing edge is preferably the edge of the door leaf which is remote from the sliding door opening in the opened state of the sliding door.

Ferner bevorzugt dichtet das Dichtungselement die Stirnseite der Führungsschiene der Schiebetür gegen einen Luftaustausch zwischen dem Innenraum des Fahrzeugs und der äußeren Umgebung des Fahrzeugs luftdicht ab.

So passiert beziehungsweise durchfährt beispielsweise der in Figur 4 links dargestellte Türflügel 2 bei einer Öffnung der Schiebetür 1 ebenfalls das linke Endstück 16. In diesem Ausführungsbeispiel weisen die Endstücke 16 rein beispielhaft jeweils eine rechteckige Form auf, in welcher eine die Führungsunterstützung bildende beziehungsweise die Führung der Türflügel 2 ermöglichende, durchgehende Aussparung vorgesehen ist, welche die U-förmige Innenkontur 5 der Führungsschiene 3 nachbildet. Es können allerdings auch Führungsschienen 3 mit Basisstücken 19 mit anderen Führungsprofilen samt zugehörigen beziehungsweise darauf abgestimmten Endstücken 16 realisiert werden. Auch die Formen solcher Endstücke 16 können von der in der Figur 3 dargestellten abweichen. Die Endstücke 16 sind in der Figur 3 schraffiert dargestellt.The end pieces 16 thus form as part of the guide rail 3 in each case an extension of the base piece 19, which likewise contributes to the guidance of a door leaf 2. Thus, for example, the door leaf 2 shown on the left in FIG. 4 also passes or passes through the left-hand end piece 16 in this embodiment. In this exemplary embodiment, the end pieces 16 have a rectangular shape, by way of example only, in which the guide support forms the guide Door 2 enabling, continuous recess is provided, which simulates the U-shaped inner contour 5 of the guide rail 3. However, it is also possible to realize guide rails 3 with base pieces 19 with other guide profiles together with associated or matched end pieces 16. The shapes of such end pieces 16 can of the in the FIG. 3 differ. The end pieces 16 are in the FIG. 3 hatched shown.

In diesem Ausführungsbeispiel weisen die Türflügel 2 jeweils eine teilweise in der Führungsschiene 3 zum Zwecke der Führung befindliche Kante 8 auf, welche im zusammengebauten und geschlossenen Zustand der Schiebetür 1 jeweils in einer Richtung entlang der Führungsschiene 3 über die Stirnseite 4 der Führungsschiene 3 hinausragt. Es steht also jeweils ein Teil der in die Führungsschiene 3 eingeführten Unterkante 8 jeweils eines Türflügels 2 im geschlossenen Zustand der Schiebetür 1 über die durch das Endstück 16 gebildete Verlängerung des Basisstücks 19 über. Da die ersten Enden 15 der Nebenschließkanten 10 der Türflügel 2 senkrecht auf den Enden der teilweise in die Führungsschiene 3 eingeführten Kanten 8 stehen, liegen die an den Nebenschließkanten 10 angeordneten Dichtungselemente 13 im geschlossenen Zustand der Schiebetür 1 dichtend auf den Stirnseiten 4, also auf den Gegenauflageflächen 17 der jeweiligen Endstücke 16 auf und überlappen diese.
