Description

Die vorliegende Anmeldung betrifft eine Vorrichtung zur Führung eines Türelements, insbesondere einer Schiebetür für ein Personenbeförderungsfahrzeug beispielsweise für Busse oder Schienenfahrzeuge des öffentlichen Nahverkehrs. Derartige Vorrichtungen sind aus dem Stand der Technik bekannt.The present application relates to a device for guiding a door element, in particular a sliding door for a passenger transport vehicle, for example for buses or rail vehicles in local public transport. Such devices are known from the prior art.

Bei dieser Art von Fahrzeugen wird aufgrund der vorliegenden Einbaugegebenheiten die Führung der Türelemente einachsig ausgeführt. Hierzu werden beispielsweise Laufrollen, welche mittels geeigneter Lagerelemente an dem Türelement befestigt sind, in einachsigen Führungsprofilen geführt. Im täglichen Fahrbetrieb sind die Türelemente aufgrund von Straßenunebenheit oder den Unebenheiten bei den Schienenanlagen ständigen Bewegungen ausgesetzt. Da die Bewegungen sich auf die Führungsprofile übertragen, sind diese im Fahrbetrieb hohen Kräften ausgesetzt. Um dem entgegenzuwirken, müssen diese kompensiert werden. Zudem ist bei einer starren Verbindung zwischen dem Türelement und der Laufrolle eine hohe Genauigkeit des Führungsprofils erforderlich, da die Laufrollen auf dauerhafte Anlage bei der Montage eingestellt werden.In this type of vehicle, due to the existing installation conditions, the door elements are guided on one axis. For this purpose, for example, rollers, which are attached to the door element by means of suitable bearing elements, are guided in uniaxial guide profiles. In daily driving, the door elements are exposed to constant movements due to unevenness in the road or the unevenness of the rail systems. Since the movements are transferred to the guide profiles, they are exposed to high forces when driving. To counteract this, these must be compensated. In addition, with a rigid connection between the door element and the roller, a high degree of accuracy of the guide profile is required, since the rollers are set to permanent contact during assembly.

Weiterhin sind Vorrichtungen bekannt, bei denen die Lagerung bei größeren auftretenden Bewegungen in einer Richtung elastisch ausgeführt wird. Bei einer Umsetzung mit zwei Rollen dient beispielsweise die elastisch gelagerte Rolle als sogenannte Anpressrolle und die fest gelagerte Rolle als Führungsrolle.Devices are also known in which the bearing is designed to be elastic in one direction when larger movements occur. In an implementation with two rollers, for example, the elastically mounted roller serves as a so-called pressure roller and the fixed roller as a guide roller.

Weitere Führungseinrichtungen sind beispielsweise aus den Druckschriften JP 2009 155792 A , DE 199 54 111 A1 und DE 10 2007 038842 A1 bekannt. Diese beschreiben unterschiedliche Konstruktionen, die aber allesamt relativ aufwändig konstruiert sind und deren Wartungsaufwand verhältnismäßig hoch ist.Other guide devices are, for example, from the publications JP 2009 155792 A , DE 199 54 111 A1 and DE 10 2007 038842 A1 known. These describe different constructions, all of which are constructed in a relatively complex manner and require relatively high maintenance.

Der Erfindung liegt die Aufgabe zu Grunde eine gegenüber dem Stand der Technik verbesserte Vorrichtung zur Führung eines Türelements, insbesondere einer Schiebetür für ein Personenbeförderungsfahrzeug bereitzustellen. Insbesondere hat sich die Erfindung zum Ziel gemacht, eine Vorrichtung zur Führung eines Türelements bereitzustellen, die zuverlässig funktioniert und einen relativ geringen Wartungsaufwand aufweist.The object of the invention is to provide a device for guiding a door element, in particular a sliding door for a passenger transport vehicle, which is improved compared to the prior art. In particular, the invention has made it its aim to provide a device for guiding a Provide door element that works reliably and has a relatively low maintenance.

Gelöst wird diese Aufgabe durch eine Vorrichtung mit den Merkmalen des Patentanspruchs 1. Vorteilhafte Ausgestaltungen und Varianten der Erfindung ergeben sich aus den abhängigen Ansprüchen und der nachfolgenden Beschreibung. Erfindungsgemäß ist vorgesehen, dass die Vorrichtung zur Führung eines Türelements, insbesondere einer Schiebetür für ein Personenbeförderungsfahrzeug ein Führungsprofil zur Führung des Türelements enthält, wobei das Türelement über mindestens ein elastisches Lagerelement elastisch mit mindestens einem Laufrollenpaar verbunden ist, so dass das Türelement bei einer Krafteinwirkung quer zur seiner Längsachse bewegbar ist.This object is achieved by a device having the features of patent claim 1. Advantageous refinements and variants of the invention result from the dependent claims and the following description. According to the invention, it is provided that the device for guiding a door element, in particular a sliding door for a passenger transport vehicle, contains a guide profile for guiding the door element, with the door element being elastically connected to at least one pair of rollers via at least one elastic bearing element, so that the door element can move transversely when a force is applied is movable to its longitudinal axis.

Hierdurch wird eine elastische Führung des Türelements, insbesondere einer Schiebetür für ein Personenbeförderungsfahrzeug erreicht. Durch die elastische Ausführung werden die Kräfte, denen die Türelemente im täglichen Fahrbetrieb ausgesetzt sind besser absorbiert. Ferner können die Führungsprofile größere Fehlertoleranzen aufweisen, da eventuell vorhandene Unebenheiten durch die elastische Ausgestaltung ausgeglichen werden.This achieves elastic guidance of the door element, in particular of a sliding door for a passenger transport vehicle. Due to the elastic design, the forces to which the door elements are exposed in everyday driving are better absorbed. Furthermore, the guide profiles can have greater error tolerances, since any unevenness that may be present is compensated for by the elastic design.

Dadurch, dass das Türelement bei einer Krafteinwirkung, beispielsweise einer von außen auftretenden Kraft, quer zur seiner Längsachse bewegbar ist, wird ermöglicht, dass das Türelement außerhalb eines durch das Führungsprofil begrenzten Bereichs gebracht werden kann. So ist beispielsweise möglich ein gewünschtes Anliegen des Türelements außerhalb des Führungsprofils zu bewirken. Gemäß einer bevorzugten Ausführungsvariante ist eine erste Laufrolle des Laufrollenpaars über ein erstes elastisches Lagerelement und eine zweite Laufrolle des Laufrollenpaars über ein zweites elastisches Lagerelement mit dem Türelement elastisch verbunden. Bei dieser Ausführung ist das Türelement über mindestens zwei elastische Lagerelemente elastisch mit mindestens einem Laufrollenpaar verbunden.Because the door element can be moved transversely to its longitudinal axis when a force is applied, for example an external force, it is possible for the door element to be brought outside of a region delimited by the guide profile. For example, it is possible to bring about a desired contact of the door element outside of the guide profile. According to a preferred embodiment variant, a first roller of the pair of rollers is elastically connected to the door element via a first elastic bearing element and a second roller of the pair of rollers is elastically connected to the door element via a second elastic bearing element. In this embodiment, the door element is elastically connected to at least one pair of rollers via at least two elastic bearing elements.

Vorzugsweise handelt es sich bei dem Lagerelement um eine Feder, die das Türelement mit der jeweiligen Laufrolle verbindet und diese jeweils an das Führungsprofil drückt. Die Federsteifigkeiten mit welcher die beiden Laufrollen an das Führungsprofil gedrückt werden, bestimmen dabei die Führungslinien. Beispielsweise entspricht eine gleiche Federkennlinie einer mittigen Führung des Türelements innerhalb des Führungsprofils.The bearing element is preferably a spring which connects the door element to the respective roller and this to the guide profile pushes. The spring stiffness with which the two rollers are pressed against the guide profile determine the guide lines. For example, the same spring characteristic corresponds to central guidance of the door element within the guide profile.

Erfindungsgemäß sind beide Laufrollen des Laufrollenpaars über ein drehbares Verbindungselement miteinander verbunden, wobei das drehbare Verbindungselement wiederum über mindestens eins, mehr bevorzugt zwei elastische Lagerelemente, elastisch mit dem Türelement verbunden ist. Die elastischen Lagerelemente können vorzugsweise aus einem Metall und/oder einem elastischen Kunststoff ausgebildet sein. So können die elastischen Lagerelemente beispielsweise als Metallfedern ausgeführt sein. Vorzugsweise ist der elastische Kunststoff ausgewählt aus der Gruppe der Elastomere, Thermoplaste oder thermoelastischen Elastomere. Weiterhin können die elastischen Lagerelemente vorzugsweise aus einem Verbundmaterial ausgebildet sein.According to the invention, both rollers of the pair of rollers are connected to one another via a rotatable connecting element, the rotatable connecting element in turn being elastically connected to the door element via at least one, more preferably two, elastic bearing elements. The elastic bearing elements can preferably be made of a metal and/or an elastic plastic. For example, the elastic bearing elements can be designed as metal springs. The elastic plastic is preferably selected from the group of elastomers, thermoplastics or thermoelastic elastomers. Furthermore, the elastic bearing elements can preferably be formed from a composite material.

Dabei sind die Laufrollen vorzugsweise im Bereich der jeweiligen Enden des Verbindungselements angeordnet und mittels geeigneter Mittel, beispielsweise Drehbolzen, mit dem Verbindungselement drehbar verbunden.The rollers are preferably arranged in the area of the respective ends of the connecting element and are rotatably connected to the connecting element by means of suitable means, for example pivot pins.

Je nach Ausführungsform gilt, dass sofern ein Laufrollenpaar vorgesehen ist, dieses vorzugsweise mittig auf einer, vorzugsweise unteren Stirnseite des Türelements angeordnet ist. Vorzugsweise weist das Türelement zwei, mehr bevorzugt drei Laufrollenpaare auf. Bei einer Ausführung mit zwei Laufrollenpaaren sind diese jeweils im Bereich der distalen Enden der Stirnseite des Türelements, bei einer Ausführung mit drei Laufrollenpaaren ist zudem eines mittig angeordnet.Depending on the embodiment, if a pair of rollers is provided, this is preferably arranged centrally on a preferably lower end face of the door element. The door element preferably has two, more preferably three pairs of rollers. In an embodiment with two pairs of rollers, these are each arranged in the region of the distal ends of the face of the door element, and in an embodiment with three pairs of rollers, one is also arranged in the middle.

Das Verbindungselement ist vorzugsweise als Wippe ausgeführt.The connecting element is preferably designed as a rocker.

In einer weiteren bevorzugten Ausführungsvariante weist das Verbindungselement mittig zwischen der ersten und der zweiten Laufrolle einen Drehpunkt auf, über den die Führung des Laufrollenpaars gesteuert werden kann.In a further preferred embodiment variant, the connecting element has a pivot point in the middle between the first and the second roller, via which the guidance of the pair of rollers can be controlled.

Sofern der Drehpunkt mittig zwischen den beiden Laufrollen liegt, resultiert hierdurch eine zentrische Führung des Laufrollenpaars. Bei einer zentrischen Führung des Laufrollenpaars werden die Laufrollen jeweils an die sich gegenüberliegenden Anlageflächen des Führungsprofils gedrückt und entlang dieser längs zur Längsachse des Führungsprofils geführt. Der Drehpunkt folgt somit einer zentralen Verlaufslinie innerhalb des Führungsprofils. Bei einer zentralen Führung werden die Laufrollen somit versetzt zueinander geführt. Durch Verändern des Drehpunktes zwischen den beiden Laufrollen kann die Führung auch außerzentrisch an einer definieren Linie liegen. Beispielsweise können bei einer derartigen außerzentrischen Führung beide Laufrollen an eine der beiden Anlageflächen gedrückt und entlang dieser geführt werden. In diesem Fall werden die Laufrollen nicht zueinander versetzt, sondern in einer Linie geführt.If the pivot point is in the middle between the two rollers, this results in a centric guidance of the pair of rollers. In the case of a centric guidance of the pair of rollers, the rollers are attached to the opposite ones Pressed contact surfaces of the guide profile and guided along this along the longitudinal axis of the guide profile. The pivot thus follows a central course line within the guide profile. In the case of a central guide, the rollers are thus guided in an offset manner in relation to one another. By changing the pivot point between the two rollers, the guide can also be off-center on a defined line. For example, with such an off-center guide, both rollers can be pressed against one of the two contact surfaces and guided along it. In this case, the rollers are not offset from each other, but are guided in one line.

In einer vorteilhaften Ausgestaltung sind die Laufrollen des Laufrollenpaars innerhalb des Führungsprofils zueinander versetzt angeordnet. Die Verlaufslinien der beiden Laufrollen sind demnach parallel zueinander im außerzentrischen Bereich des Führungsprofils.In an advantageous embodiment, the rollers of the pair of rollers are arranged offset to one another within the guide profile. The lines of progression of the two rollers are therefore parallel to one another in the off-center area of the guide profile.

Vorzugsweise weist das Führungsprofil einen ersten und einen zweiten Schenkel auf, so dass es im Wesentlichen U-förmig ausgebildet ist. Hierdurch entsteht innerhalb des Führungsprofils ein Führungskanal, in dem das Laufrollenpaar geführt werden kann.The guide profile preferably has a first and a second leg, so that it is essentially U-shaped. This creates a guide channel within the guide profile, in which the pair of rollers can be guided.

Vorzugsweise ist das Führungsprofil einläufig ausgeführt, so dass wenig Bauraum für die erfindungsgemäße Vorrichtung verbraucht wird.The guide profile is preferably designed in one run, so that little installation space is required for the device according to the invention.

In einer besonders bevorzugten Ausführungsvariante ist der Abstand zwischen der ersten und der zweiten Anlagefläche größer als der Durchmesser der Laufrollen, so dass hierdurch in Kombination mit dem jeweiligen Drehpunkt des Verbindungselements unterschiedliche Führungen des Laufrollenpaars realisiert werden können.In a particularly preferred embodiment, the distance between the first and the second contact surface is greater than the diameter of the rollers, so that in combination with the respective pivot point of the connecting element, different guidance of the pair of rollers can be implemented.

In einer weiteren besonders bevorzugten Ausführungsvariante weist das Führungsprofil an einem seiner Schenkel ein Dichtungselement auf. Durch die Möglichkeit einer Querbewegung des Türelements kann das elastische Lagerelement mit dem Dichtungselement eine dichtende Verbindung, beispielsweise im geschlossenen Zustand erzeugen.In a further particularly preferred embodiment variant, the guide profile has a sealing element on one of its legs. Due to the possibility of a transverse movement of the door element, the elastic bearing element can create a sealing connection with the sealing element, for example in the closed state.

Im Folgenden wird die Erfindung anhand von Zeichnungen näher erläutert. Im Einzelnen zeigen:

  • Fig. 1 eine Darstellung einer ersten Ausführungsform eines Teils der erfindungsgemäßen Vorrichtung, und
  • Fig. 2 eine Querschnittsdarstellung einer ersten Ausführungsform der erfindungsgemäßen Vorrichtung.
The invention is explained in more detail below with reference to drawings. Show in detail:
  • 1 a representation of a first embodiment of a part of the device according to the invention, and
  • 2 a cross-sectional view of a first embodiment of the device according to the invention.

Fig. 1 zeigt eine Darstellung einer ersten Ausführungsform eines Teils der erfindungsgemäßen Vorrichtung. Gezeigt ist ein einläufiges Führungsprofil 10 mit einem ersten und einem zweiten Schenkel 11, 12. Die Schenkel 11, 12 bilden innenseitig eine erste und eine zweite Anlagefläche 13, 14 an die eine erste und eine zweite Laufrolle 21, 22 eines Laufrollenpaars 20 gedrückt und entlang dieser längs zur Längsachse des Führungsprofils 10 geführt werden. Der zwischen der ersten und der zweiten Anlagefläche 13, 14 gebildete Abstand ist hierbei größer als der Durchmesser der jeweiligen Laufrollen 21, 22. 1 shows a representation of a first embodiment of a part of the device according to the invention. Shown is a single-track guide profile 10 with a first and a second leg 11, 12. On the inside, the legs 11, 12 form a first and a second contact surface 13, 14 pressed against and along the first and second roller 21, 22 of a pair of rollers 20 these are guided along the longitudinal axis of the guide profile 10. The distance formed between the first and the second contact surface 13, 14 is greater than the diameter of the respective rollers 21, 22.

Die Laufrollen 21, 22 des Laufrollenpaars 20 sind über ein drehbares Verbindungselement 23, beispielsweise eine Wippe, miteinander verbunden. Wie der Darstellung zu entnehmen ist, sind die Laufrollen 21, 22 im Bereich der jeweiligen Enden des Verbindungselements 23 bzw. der Wippe angeordnet und mittels geeigneter Drehelemente 24, 25, beispielsweise Drehbolzen, mit dem Verbindungselement 23 bzw. der Wippe drehbar verbunden. Weiterhin weist das Verbindungselement 23 bzw. die Wippe, einen Drehpunkt 26 auf. In der in Fig. 1 gezeigter Darstellung liegt der Drehpunkt 26 mittig zwischen den beiden Laufrollen 21, 22, so dass hierdurch eine zentrische Führung des Laufrollenpaars 20 resultiert. Bei einer zentrischen Führung des Laufrollenpaars 20 werden die Laufrollen 21, 22 jeweils an die sich gegenüberliegenden Anlageflächen 13, 14 gedrückt und entlang dieser längs zur Längsachse des Führungsprofils geführt. Der Drehpunkt 26 der Wippe 23 folgt somit einer zentralen Verlaufslinie innerhalb des Führungsprofils 10. Dadurch werden die Laufrollen 21, 22 des Laufrollenpaars 20 nicht auf einer Linie sondern versetzt zueinander geführt. Durch Verändern des Drehpunktes 26 zwischen den beiden Laufrollen 21, 22 kann die Führung auch außerzentrisch an einer definieren Linie liegen. Beispielsweise können bei einer derartigen außerzentrischen Führung beide Laufrollen 21, 22 an eine der beiden Anlageflächen 13, 14 gedrückt und entlang dieser geführt werden. In diesem Fall werden die Laufrollen 21, 22 nicht zueinander versetzt sondern in einer Linie geführt.The rollers 21, 22 of the pair of rollers 20 are connected to one another via a rotatable connecting element 23, for example a rocker. As can be seen from the illustration, the rollers 21, 22 are arranged in the region of the respective ends of the connecting element 23 or the rocker and are rotatably connected to the connecting element 23 or the rocker by means of suitable rotating elements 24, 25, for example pivot pins. Furthermore, the connecting element 23 or the rocker has a pivot point 26 . in the in 1 In the illustration shown, the pivot point 26 lies in the middle between the two rollers 21, 22, so that the pair of rollers 20 is guided centrally as a result. If the pair of rollers 20 is guided centrally, the rollers 21, 22 are each pressed against the opposing contact surfaces 13, 14 and are guided along them along the longitudinal axis of the guide profile. The pivot point 26 of the rocker 23 thus follows a central course line within the guide profile 10. As a result, the rollers 21, 22 of the pair of rollers 20 are not guided on a line but offset from one another. By changing the pivot point 26 between the two rollers 21, 22, the guide can also be off-center on a defined line. For example, with such an off-center guide, both rollers 21, 22 on one of the two Contact surfaces 13, 14 are pressed and guided along them. In this case, the rollers 21, 22 are not offset from one another but are guided in one line.

Weiterhin ist an dem Verbindungselement 23 ein elastisches Lagerelement 27 mittig angeordnet, das mit dem Türelement 30 elastisch verbunden ist.Furthermore, an elastic bearing element 27 is arranged centrally on the connecting element 23 and is elastically connected to the door element 30 .

Fig. 2 zeigt eine Querschnittsdarstellung einer ersten Ausführungsform der erfindungsgemäßen Vorrichtung. Das Türelement 30, insbesondere eine Schiebetür für ein Personenbeförderungsfahrzeug ist über ein elastisches Lagerelement 27 mit dem Verbindungselement 23 verbunden. Das elastische Lagerelement 27 kann beispielsweise als Feder ausgeführt sein. Durch die elastische Lagerung des Verbindungselements 23 bzw. der Wippe kann das Türelement 30 außerhalb des durch das Führungsprofil 10 begrenzten Bereichs gebracht werden, um beispielsweise ein bewusstes Anliegen des Türelements 30 außerhalb des Führungsprofils 10 hervorzurufen. Durch die elastische Lagerung der Wippe 23 kann das Türelement 30 somit quer zum Führungsprofil 10 bewegt werden, wenn es einer von außen eingebrachten Kraft ausgesetzt wird. Infolge der Querbewegung kann das elastische Lagerelement 27 mit einem in einem Schenkel 11 des Führungsprofils 10 angeordnetem Dichtungselement 15 eine dichtende Verbindung, beispielsweise im geschlossenen Zustand des Türelements erzeugen. 2 shows a cross-sectional representation of a first embodiment of the device according to the invention. The door element 30 , in particular a sliding door for a passenger transport vehicle, is connected to the connecting element 23 via an elastic bearing element 27 . The elastic bearing element 27 can be designed as a spring, for example. Due to the elastic mounting of the connecting element 23 or the rocker, the door element 30 can be brought outside of the area delimited by the guide profile 10 in order, for example, to cause the door element 30 to deliberately rest outside of the guide profile 10 . Due to the elastic mounting of the rocker 23, the door element 30 can thus be moved transversely to the guide profile 10 when it is exposed to a force introduced from the outside. As a result of the transverse movement, the elastic bearing element 27 can produce a sealing connection with a sealing element 15 arranged in a leg 11 of the guide profile 10, for example in the closed state of the door element.
