Description

Die Erfindung betrifft eine Anordnung zur Führung einer Schiebetür, umfassend wenigstens ein Schienenprofil und wenigstens einen relativ zum wenigstens einen Schienenprofil in Längsrichtung verfahrbar gelagerten Laufwagen, an welchem die Schiebetür befestigbar ist, wobei der wenigstens eine Laufwagen wenigstens einen Wälzkörper und das wenigstens eine Schienenprofil wenigstens eine in Längsrichtung des Schienenprofils verlaufende Lauffläche aufweist, an welcher sich der wenigstens eine Wälzkörper abstützt, wobei der wenigstens eine Walzkörper an der wenigstens einen Lauffläche quer zur Längsrichtung des wenigstens einen Schienenprofils verschiebbar ist, so dass der wenigstens eine Laufwagen um eine im Wesentlichen parallel zur Längsrichtung des wenigstens einen Schienenprofils verlaufenden Schwenkachse Schwenkbar ist. Die Erfindung betrifft weiterhin ein Möbel mit wenigstens einer Schiebetür und wenigstens einer solchen Anordnung.The invention relates to an arrangement for guiding a sliding door, comprising at least one rail profile and at least one carriage mounted so that it can move in the longitudinal direction relative to the at least one rail profile, to which the sliding door can be attached, the at least one carriage having at least one rolling element and the at least one rail profile having at least one running surface running in the longitudinal direction of the rail profile, on which the at least one rolling body is supported, the at least one rolling body being displaceable on the at least one running surface transversely to the longitudinal direction of the at least one rail profile, so that the at least one carriage moves by a distance substantially parallel to the longitudinal direction the pivot axis running at least one rail profile can be pivoted. The invention further relates to a piece of furniture with at least one sliding door and at least one such arrangement.

Figur 2 zeigt eine Anordnung 101 zur Führung einer Schiebetür gemäß dem Stand der Technik in einer Seitenansicht, wobei ein durch einen Kreis markierter Ausschnitt im unteren Teil der Figur vergrößert dargestellt ist. Die Anordnung 101 weist ein Schienenprofil 103 und einen dazu relativ in Längsrichtung, welche in dieser Ansicht normal zur Blattebene orientiert ist, verfahrbar gelagerten Laufwagen 105. Der Laufwagen 105 weist im oberen Bereich einen um eine vertikale Achse gelagerten Wälzkörper 106 auf, welcher sich an einer in Längsrichtung verlaufenden Lauffläche 107 des Schienenprofils 103 abstützt. Figure 2 shows an arrangement 101 for guiding a sliding door according to the prior art in a side view, with a section marked by a circle in the lower part of the figure being shown enlarged. The arrangement 101 has a rail profile 103 and a carriage 105 which is movably mounted relative to it in the longitudinal direction, which in this view is oriented normal to the plane of the sheet. The carriage 105 has in the upper region a rolling element 106 which is mounted about a vertical axis and which is located on a running surface 107 of the rail profile 103 running in the longitudinal direction.

Am Laufwagen 105 ist über ein Laufwagenscharnier 118 eine Schiebetür befestigbar. Die Schiebetür, welche in der Zeichnung nicht dargestellt ist, ist im oberen Bereich mit dem Laufwagenscharnier 118 verbunden und hängt nach unten. Die Schiebetür weist ein hohes Gewicht auf. Unter dem Einfluss der Schwerkraft hat die Schiebetür im unteren Bereich das Bestreben, nach rechts zu schwenken. Dadurch übt die Schiebetür ein Drehmoment auf die Anordnung 101 aus, welches durch einen gekrümmten Pfeil angedeutet ist.A sliding door can be attached to the carriage 105 via a carriage hinge 118. The sliding door, which is not shown in the drawing, is connected in the upper area to the carriage hinge 118 and hangs downwards. The sliding door is heavy. Under the influence of gravity, the sliding door in the lower area tends to swing to the right. As a result, the sliding door exerts a torque on the arrangement 101, which is indicated by a curved arrow.

Wie aus der vergrößerten Darstellung hervorgeht, wird der Wälzkörper 106 in weiterer Folge im Kontaktbereich 29 gegen die Lauffläche 107 gepresst. Befindet sich die Schiebetür über einen längeren Zeitraum, z.B. mehrere Tage, unbewegt in derselben Stellung, so kommt es zu einer Abplattung des Wälzkörpers 106. Wenn anschließend der Wälzkörper 106 wieder entlang des Schienenprofils 103 bewegt wird, so kommt es durch diese Abplattung zu einer unvorteilhaften Geräuschentwicklung, einem Rattern. Gleichzeitig kann es zu einem vergrößerten Verschleiß des Wälzkörpers 106 und des Schienenprofils 103 kommen.As can be seen from the enlarged view, the rolling body 106 is subsequently pressed against the running surface 107 in the contact area 29. If the sliding door is in the same position for a longer period of time, e.g. several days, the rolling element 106 becomes flattened. If the rolling element 106 is then moved again along the rail profile 103, this flattening results in an unfavorable situation Noise development, a rattling. At the same time, increased wear on the rolling element 106 and the rail profile 103 can occur.

Die DE 202017101296 U1 offenbart eine Führung einer Schiebetür mit einem Winkelausgleich, in welcher ein Laufwagen mit Rollen vorgesehen ist, der an der Innenseite einer rohrförmigen Führungsbahn geführt wird.The DE 202017101296 U1 discloses a guide of a sliding door with an angle compensation, in which a carriage with rollers is provided, which is guided on the inside of a tubular guideway.

DE 564 572 offenbart eine Führung einer Schiebetür, wobei das Schienenprofil eine in Längsrichtung des Schienenprofils verlaufende Lauffläche aufweist, an welcher sich ein Wälzkörper abstützt. DE 564 572 discloses a guide for a sliding door, wherein the rail profile has a running surface running in the longitudinal direction of the rail profile, on which a rolling element is supported.

Die Aufgabe der vorliegenden Erfindung besteht darin, eine gegenüber dem Stand der Technik verbesserte Anordnung zur Führung einer Schiebetür sowie ein Möbel mit wenigstens einer Schiebetür und wenigstens einer solchen verbesserten Anordnung anzugeben, bei welcher insbesondere ein Abplatten des Wälzkörper signifikant reduziert oder gänzlich vermieden wird.The object of the present invention is to provide an arrangement for guiding a sliding door that is improved over the prior art and a piece of furniture with at least one sliding door and at least one such improved arrangement, in which, in particular, flattening of the rolling element is significantly reduced or completely avoided.

Diese Aufgabe wird gelöst durch die Merkmale der unabhängigen Ansprüche 1 und 11. Es istvorgesehen, dass der wenigstens eine Wälzkörper an der wenigstens einen Lauffläche quer zur Längsrichtung des wenigstens einen Schienenprofils verschiebbar ist, so dass der wenigstens eine Laufwagen um eine im Wesentlichen parallel zur Längsrichtung des wenigstens einen Schienenprofils verlaufende Schwenkachse verschwenkbar ist.This object is achieved by the features of independent claims 1 and 11. It is provided that the at least one rolling body on the at least one running surface is displaceable transversely to the longitudinal direction of the at least one rail profile, so that the at least one carriage moves by a distance substantially parallel to the longitudinal direction The pivot axis running at least one rail profile can be pivoted.

Bei der erfindungsgemäßen Anordnung ist es vorgesehen, dass das wenigstens eine Schienenprofil wenigstens einen in Längsrichtung verlaufenden Vertikalsteg, welcher im Wesentlichen senkrecht zur wenigstens einen Lauffläche ausgerichtet ist, aufweist, wobei der wenigstens eine Laufwagen derart um die Schwenkachse verschwenkbar ist, dass sich ein Abstand zum wenigstens einen Vertikalsteg in einem durch die Schiebetür belasteten Zustand vergrößert, vorzugsweise wobei der wenigstens eine Vertikalsteg die wenigstens eine Lauffläche quer zur Längsrichtung des wenigstens einen Schienenprofils begrenzt.In the arrangement according to the invention, it is provided that the at least one rail profile has at least one vertical web running in the longitudinal direction, which is aligned essentially perpendicular to the at least one running surface, wherein the at least one carriage is pivotable about the pivot axis in such a way that a distance from the at least one vertical web is enlarged in a state loaded by the sliding door, preferably wherein the at least one vertical web which delimits at least one running surface transversely to the longitudinal direction of the at least one rail profile.

Eine Grundidee besteht darin, ein Verschwenken der Schiebetür und damit des Laufwagens bewusst zuzulassen. Der wenigstens eine Wälzkörper kann dabei an der wenigstens einen Lauffläche quer zur Längsrichtung des wenigstens einen Schienenprofils verschoben werden, und läuft somit ins Leere, ohne gegen einen Steg oder dergleichen gepresst zu werden. Ein Abplatten des wenigstens einen Wälzkörpers kann also gar nicht stattfinden.A basic idea is to consciously allow the sliding door and thus the carriage to pivot. The at least one rolling element can be displaced on the at least one running surface transversely to the longitudinal direction of the at least one rail profile, and thus runs into the void without being pressed against a web or the like. The at least one rolling element cannot flatten at all.

Gemäß einer bevorzugten Ausführungsform ist es vorgesehen, dass die wenigstens eine Lauffläche im Querschnitt zumindest bereichsweise konkav ausgebildet ist, und/oder wobei der wenigstens eine Wälzkörper eine Umfangsfläche aufweist, über welche sich der wenigstens eine Wälzkörper zumindest bereichsweise an der wenigstens einen Lauffläche abstützt, und wobei die Umfangsfläche im Querschnitt zumindest bereichsweise konvex ausgebildet ist. Diese Ausführungsformen - einzeln oder in Kombination miteinander - ermöglichen ein sanftes Verschieben des wenigstens einen Wälzkörpers an der Lauffläche quer zur Längsrichtung des Schienenprofils. Die Reibungskräfte werden minimiert, ohne dass es bei einem Verschwenken des wenigstens einen Laufwagens um die Schwenkachse zu einem Anheben des wenigstens einen Wälzkörpers von der Lauffläche und damit zu einem Abreißen des Kraftstrangs kommt.According to a preferred embodiment, it is provided that the at least one running surface is concave in cross section at least in some areas, and / or wherein the at least one rolling body has a circumferential surface over which the at least one rolling body is supported at least in some areas on the at least one running surface, and wherein the peripheral surface is convex in cross section at least in some areas. These embodiments - individually or in combination with each other - enable a gentle displacement of the at least one rolling element on the running surface transversely to the longitudinal direction of the rail profile. The frictional forces are minimized without the at least one rolling element being lifted from the running surface and thus the power train being torn off when the at least one carriage is pivoted about the pivot axis.

Weiterhin hat es sich als vorteilhaft herausgestellt, dass das wenigstens eine Schienenprofil wenigstens ein Begrenzungsprofil aufweist, welches die wenigstens eine Lauffläche quer zur Längsrichtung des wenigstens einen Schienenprofils begrenzt. Dieses wenigstens eine Begrenzungsprofil ist nur für einen außerplanmäßigen Überlastfall gedacht, um ein Aushängen der Schiebetür zu verhindern. Im Regelbetrieb steht der wenigstens eine Wälzkörper mit dem wenigstens einen Begrenzungsprofil nicht oder nur mit einer minimalen Andrückkraft in Kontakt.Furthermore, it has proven to be advantageous that the at least one rail profile has at least one boundary profile, which delimits the at least one running surface transversely to the longitudinal direction of the at least one rail profile. This at least one limiting profile is only intended for an unscheduled overload event in order to prevent the sliding door from being unhooked. In regular operation, the at least one rolling element is not in contact with the at least one boundary profile or is only in contact with a minimal pressing force.

Als günstig hat es sich erwiesen, dass der wenigstens eine Laufwagen ausgehend von einer Nulllage, welche der wenigstens eine Laufwagen zumindest in einem durch die Schiebetür unbelasteten Zustand einnimmt, um die Schwenkachse in einem Winkelbereich von +15° und -10°, vorzugsweise +10° und -5°, verschwenkbar ist. Diese relativ kleine Verschwenkung reicht überraschenderweise bereits aus, um ein Abplatten des wenigstens einen Wälzkörpers zu verhindern.It has proven to be advantageous that the at least one carriage starts from a zero position, which of the at least one carriage at least in one through the Sliding door assumes unloaded state, can be pivoted about the pivot axis in an angular range of +15° and -10°, preferably +10° and -5°. This relatively small pivoting is surprisingly enough to prevent the at least one rolling element from flattening.

Es kann vorgesehen sein, dass der wenigstens eine Wälzkörper im Wesentlichen zylinderförmig ausgebildet ist. Es sind aber auch andere Wälzkörperformen möglich.It can be provided that the at least one rolling body is essentially cylindrical. However, other rolling body shapes are also possible.

Weiterhin kann es vorgesehen sein, dass der wenigstens eine Wälzkörper um eine im Wesentlichen senkrecht zur Schwenkachse verlaufende Drehachse drehbar am wenigstens einen Laufwagen gelagert ist, wobei die Drehachse im Montagzustand im Wesentlichen horizontal ausgerichtet ist. Im Vergleich zu dem in der Figur 2 dargestellten Stand der Technik ist die Drehachse des wenigstens einen Wälzkörpers also um 90° gedreht.Furthermore, it can be provided that the at least one rolling body is rotatably mounted on at least one carriage about an axis of rotation running essentially perpendicular to the pivot axis, the axis of rotation being aligned essentially horizontally in the assembled state. Compared to that in the Figure 2 In the prior art shown, the axis of rotation of the at least one rolling element is rotated by 90 °.

Gemäß einer bevorzugten Ausführungsform ist es vorgesehen, dass der wenigstens eine Laufwagen wenigstens einen Lastwälzkörper zur Abstützung des Gewichts einer am wenigstens einen Laufwagen befestigten Schiebetüre aufweist, bevorzugt wobei der wenigstens eine Lastwälzkörper im Querschnitt am Umfang eine Nut, besonders bevorzugt V-Nut, aufweist. Wenn der wenigstens eine Lastwälzkörper am Umfang eine Nut aufweist, übernimmt der wenigstens eine Lastwälzkörper nicht nur eine tragende Funktion, sondern kann auch zur seitlichen Führung des wenigstens einen Laufwagens eingesetzt werden.According to a preferred embodiment, it is provided that the at least one carriage has at least one load rolling body for supporting the weight of a sliding door attached to the at least one carriage, preferably wherein the at least one load rolling body has a groove, particularly preferably a V-groove, in cross section on the circumference. If the at least one load rolling body has a groove on the circumference, the at least one load rolling body not only takes on a supporting function, but can also be used for lateral guidance of the at least one carriage.

In diesem Zusammenhang hat es sich als vorteilhaft erwiesen, dass das wenigstens eine Schienenprofil wenigstens eine lastübertragende Lauffläche aufweist, an welcher sich der wenigstens eine Lastwälzkörper abstützt, bevorzugt wobei die wenigstens eine lastübertragende Lauffläche im Querschnitt zumindest bereichsweise konvex, besonders bevorzugt kreisförmig, ausgebildet ist. Durch eine solche Ausführung kann einerseits die Auflagefläche zwischen dem wenigstens einen Lastwälzkörper und der wenigstens einen lastübertragenden Lauffläche minimiert werden. Andererseits ist es möglich, wenn der wenigstens eine Lastwälzkörper am Umfang eine Nut aufweist, einen Eingriff der wenigstens einen lastübertragenden Lauffläche in den wenigstens einen Lastwälzkörper zu erzielen. Dadurch kann die seitliche Führung noch weiter verbessert werden.In this context, it has proven to be advantageous that the at least one rail profile has at least one load-transmitting running surface on which the at least one load rolling body is supported, preferably wherein the at least one load-transmitting running surface is convex in cross section at least in some areas, particularly preferably circular. Through such a design, on the one hand, the contact surface between the at least one load rolling body and the at least one load-transmitting running surface can be minimized. On the other hand, if the at least one load rolling body has a groove on the circumference, it is possible for the at least one load-transmitting running surface to engage in the at least one To achieve load rolling elements. This allows the lateral guidance to be further improved.

Es bietet sich weiterhin an, dass die wenigstens eine lastübertragende Lauffläche an wenigstens einem vom wenigstens einen Schienenprofil gesondert ausgebildeten Einlegeteil ausgebildet ist, vorzugsweise wobei das wenigstens eine Einlegeteil zylinderförmig ausgebildet ist.It is also advisable for the at least one load-transmitting running surface to be formed on at least one insert part which is designed separately from the at least one rail profile, preferably whereby the at least one insert part is designed to be cylindrical.

Und schließlich hat es sich als günstig herausgestellt, dass die Anordnung wenigstens ein Laufwagenscharnier umfasst, welches mit dem wenigstens einen Laufwagen und mit der Schiebetür verbunden oder verbindbar ist, und über welches die Schiebetür gegenüber dem wenigstens einen Laufwagen verschwenkbar ist, vorzugsweise um eine in Montagelage vertikale Achse.And finally, it has proven to be advantageous that the arrangement includes at least one carriage hinge, which is connected or connectable to the at least one carriage and to the sliding door, and via which the sliding door can be pivoted relative to the at least one carriage, preferably by a position in the assembly position vertical axis.

Wie eingangs ausgeführt, wird Schutz auch begehrt für ein Möbel mit wenigstens einer Schiebetür und wenigstens einer erfindungsgemäßen Anordnung, bevorzugt wobei das Möbel einen, besonders bevorzugt schachtförmigen, Hohlraum zur Aufnahme der wenigstens einen Schiebetür aufweist, wobei sich der Hohlraum im Wesentlichen quer zum wenigstens einen Schienenprofil ins Innere des Möbels erstreckt.As stated at the beginning, protection is also desired for a piece of furniture with at least one sliding door and at least one arrangement according to the invention, preferably the furniture having a, particularly preferably shaft-shaped, cavity for receiving the at least one sliding door, the cavity being essentially transverse to the at least one Rail profile extends into the interior of the furniture.

Eine bevorzugte Ausführungsform sieht vor, dass die wenigstens eine Schiebetür wenigstens zwei gelenkig miteinander verbundene Türflügel umfasst, wobei die wenigstens zwei Türflügel zwischen einer Parallelstellung, in welcher die wenigstens zwei Türflügel im Wesentlichen parallel zueinander ausgerichtet sind, und einer Komplanarstellung, in welcher die wenigstens zwei Türflügel im Wesentlichen komplanar ausgerichtet sind, bewegbar sind, wobei sich die Winkellage des wenigstens einen Laufwagens in Bezug auf die Schwenkachse bei einer Bewegung der wenigstens zwei Türflügel zwischen der Parallelstellung und der Komplanarstellung ändert.A preferred embodiment provides that the at least one sliding door comprises at least two door leaves that are articulated to one another, the at least two door leaves being between a parallel position, in which the at least two door leaves are aligned essentially parallel to one another, and a coplanar position, in which the at least two Door leaves are aligned essentially coplanar, are movable, the angular position of the at least one carriage changing in relation to the pivot axis when the at least two door leaves move between the parallel position and the coplanar position.

In diesem Zusammenhang kann es vorteilhafter Weise vorgesehen sein, dass die Neigung des wenigstens einen Laufwagens gegenüber einer Vertikalstellung in der Komplanarstellung der wenigstens zwei Türflügel größer als in der Parallelstellung der wenigstens zwei Türflügel ist.In this context, it can advantageously be provided that the inclination of the at least one carriage relative to a vertical position is greater in the coplanar position of the at least two door leaves than in the parallel position of the at least two door leaves.

Die Figur 1 zeigt ein bevorzugtes Ausführungsbeispiel eines Möbels 20 mit zwei Schiebetüren 2, welche über eine erfindungsgemäße Anordnung 1 bewegbar sind. Einzelheiten der Anordnung 1, welche ein Schienenprofil 3 und pro Schiebetür 2 jeweils einen in Längsrichtung 4 relativ zum Schienenprofil 3 verfahrbar gelagerten Laufwagen 5 umfasst, werden im Zuge der Figuren 3a) ff. beschrieben.The Figure 1 shows a preferred embodiment of a piece of furniture 20 with two sliding doors 2, which can be moved via an arrangement 1 according to the invention. Details of the arrangement 1, which includes a rail profile 3 and a carriage 5 mounted movably in the longitudinal direction 4 relative to the rail profile 3 for each sliding door 2, will be discussed in the course of Figures 3a ) ff. described.

Die Schiebetüren 2 umfassen jeweils zwei gelenkig miteinander verbundene Türflügel 22, wobei die zwei Türflügel 22 zwischen einer Parallelstellung, in welcher die zwei Türflügel 22 im Wesentlichen parallel zueinander ausgerichtet sind, und einer Komplanarstellung, in welcher die zwei Türflügel 22 im Wesentlichen komplanar ausgerichtet sind, bewegbar sind. Die in der Figur dargestellte Schiebetür 2 auf der linken Seite ist in der Komplanarstellung angeordnet. Die rechte Schiebetür 2 ist in einer Zwischenstellung, in welcher die zwei Türflügel 22 einen Winkel von in etwa 90° zueinander einschließen, angeordnet. Werden die Türflügel 22 weiter nach rechts zusammengeschoben, so erreichen sie die Parallelstellung. Die Schiebetür 2 ist in der Parallelstellung zusammengefaltet und die beiden Türflügel 22 bilden ein Türpaket. Befinden sich beide Schiebetüren 2 in der Komplanarstellung, ist das Möbel 20 nach außen hin geschlossen.The sliding doors 2 each comprise two door leaves 22 which are hingedly connected to one another, the two door leaves 22 being between a parallel position, in which the two door leaves 22 are aligned substantially parallel to one another, and a coplanar position, in which the two door leaves 22 are aligned substantially coplanar, are movable. The sliding door 2 shown in the figure on the left side is arranged in the coplanar position. The right sliding door 2 is arranged in an intermediate position in which the two door leaves 22 form an angle of approximately 90° to one another. If the door leaves 22 are pushed together further to the right, they reach the parallel position. The sliding door 2 is in the Folded in parallel position and the two door leaves 22 form a door package. If both sliding doors 2 are in the coplanar position, the furniture 20 is closed to the outside.

Im Inneren des Möbels 20 können wie im dargestellten Fall beispielsweise Bestandteile einer Küche 28 oder sogar eine vollständige Küche 28 angeordnet sein. Benachbart zum Möbel 20 können weitere Möbel, beispielsweise ein Hochschrank 25, angeordnet sein.Inside the furniture 20, for example, components of a kitchen 28 or even a complete kitchen 28 can be arranged, as in the case shown. Additional furniture, for example a tall cabinet 25, can be arranged adjacent to the furniture 20.

Die Türflügel 22 können über ein oder mehrere Türscharniere 26 miteinander verbunden sein.The door leaves 22 can be connected to one another via one or more door hinges 26.

Die Erfindung ist nicht auf zwei Schiebetüren 2 mit zwei Türflügeln 22 beschränkt. Es kann beispielsweise auch nur eine Schiebetür 2 und/oder eine Schiebetür 2 mit nur einem Türflügel 22 zum Einsatz kommen.The invention is not limited to two sliding doors 2 with two door leaves 22. For example, only one sliding door 2 and/or one sliding door 2 with only one door leaf 22 can be used.

Gemäß dem dargestellten Ausführungsbeispiel umfasst das Möbel 20 zwei schachtförmige Hohlräume 21 zur Aufnahme jeweils einer Schiebetür 2, wobei sich die Hohlräume 21 im Wesentlichen quer zum Schienenprofil 3 ins Innere des Möbels 20 erstrecken. Die Hohlräume 21 können wie im dargestellten Fall durch Seitenwände 24 begrenzt sein.According to the exemplary embodiment shown, the furniture 20 comprises two shaft-shaped cavities 21 for each accommodating a sliding door 2, the cavities 21 extending essentially transversely to the rail profile 3 into the interior of the furniture 20. The cavities 21 can be limited by side walls 24, as in the case shown.

Im Falle einer Schiebetür 2, welche zwei gelenkig miteinander verbundene Türflügel 22 aufweist, bietet es sich an, dass die Schiebetür 2 ausgehend von der Parallelstellung der Türflügel 22 im schachtförmigen Hohlraum 21 versenkbar ist.In the case of a sliding door 2, which has two hinged door leaves 22, it is advisable for the sliding door 2 to be retractable in the shaft-shaped cavity 21 starting from the parallel position of the door leaves 22.

Weiterhin bietet es sich an, einen Träger 41 vorzusehen, an welchem die Schiebetür 2 bewegbar gelagert ist. Zur bewegbaren Lagerung können Trägerscharniere 27 vorgesehen sein.Furthermore, it is advisable to provide a carrier 41 on which the sliding door 2 is movably mounted. Support hinges 27 can be provided for movable storage.

Es können eine oder mehrere von dem Schienenprofil 3 gesonderte Führungen vorgesehen sein, über welche der Träger 41 im Hohlraum 21 bewegbar ist. Die Führungen verlaufen quer zum Schienenprofil 3 und können an einer der oder an mehreren Seitenwänden 24, welche den Hohlraum 21 begrenzen, angeordnet sein.One or more guides separate from the rail profile 3 can be provided, via which the carrier 41 can be moved in the cavity 21. The guides run transversely to the rail profile 3 and can be arranged on one or more side walls 24 that delimit the cavity 21.

Insgesamt gesehen sind die Schiebetüren 2 im dargestellten Fall jeweils einerseits über einen Laufwagen 5 am Schienenprofil 3 bewegbar gelagert und andererseits mit einem im Hohlraum 21 bewegbaren Träger 41 verbunden. Zur Befestigung der Schiebetüren 2 an den jeweiligen Laufwagen 5 kann jeweils ein Laufwagenscharnier 18 vorgesehen sein, über welches die Schiebetüren 2 um eine vertikale Achse 19 relativ zu den Laufwagen 5 verschwenkbar sind.Overall, in the case shown, the sliding doors 2 are, on the one hand, movably mounted on the rail profile 3 via a carriage 5 and, on the other hand, connected to a carrier 41 that can be moved in the cavity 21. To attach the sliding doors 2 to the respective carriages 5, a carriage hinge 18 can be provided, via which the sliding doors 2 can be pivoted about a vertical axis 19 relative to the carriages 5.

Wenn die Schiebetür 2 in der Parallelstellung der Türflügel 22 im Hohlraum 21 versenkt wird, erfolgt eine Entkoppelung des Laufwagens 5 vom Schienenprofil 3.If the sliding door 2 is sunk into the cavity 21 in the parallel position of the door leaves 22, the carriage 5 is decoupled from the rail profile 3.

Es sind auch Ausführungsformen möglich, bei denen beispielsweise ein durchgängiges Schienenprofil 3 zum Einsatz kommt, welches über eine Kurve in den Hohlraum 21 hinein verläuft. In diesem Fall kann auf den Einsatz eines Trägers 41, gesonderte Führungen für den Träger 41, und/oder eine Entkoppelung des Laufwagens 5 vom Schienenprofil 3 verzichtet werden.Embodiments are also possible in which, for example, a continuous rail profile 3 is used, which runs over a curve into the cavity 21. In this case, the use of a carrier 41, separate guides for the carrier 41, and/or a decoupling of the carriage 5 from the rail profile 3 can be dispensed with.

Wie eingangs in Zusammenhang mit der Figur 2 beschrieben, haben die Schiebetüren 2 das Bestreben, unter dem Einfluss der Schwerkraft im ihrem unteren Bereich nach innen, also in Richtung des Möbelinnenraums, zu verschwenken. Dieser Sachverhalt ist in der Figur 1 bei der linken Schiebetür 2 durch einen Pfeil angedeutet.As at the beginning in connection with the Figure 2 described, the sliding doors 2 tend to pivot inwards in their lower area, i.e. towards the furniture interior, under the influence of gravity. This situation is in the Figure 1 indicated by an arrow on the left sliding door 2.

Dieses Bestreben ist je nach Stellung der beiden Türflügel 22 unterschiedlich stark ausgeprägt. Und zwar haben die Schiebetüren 2 in der Komplanarstellung eine stärker ausgeprägte Tendenz, nach innen zu verschwenken, als in der Parallelstellung. Auch im Zuge der Bewegung der Schiebetüren 2 zwischen diesen beiden Stellungen kann die Tendenz unterschiedlich stark ausgeprägt sein.This effort varies depending on the position of the two door leaves 22. The sliding doors 2 have a more pronounced tendency to pivot inwards in the coplanar position than in the parallel position. The tendency can also vary in intensity as the sliding doors 2 move between these two positions.

Die Figur 2 zeigt eine Anordnung gemäß dem Stand der Technik. Diese Anordnung, von welcher sich die vorliegende Erfindung abgrenzt, wurde bereits eingangs beschrieben.The Figure 2 shows an arrangement according to the prior art. This arrangement, from which the present invention differs, has already been described at the beginning.

Die Figuren 3a) bis 4c) zeigen ein erstes bevorzugtes Ausführungsbeispiel der erfindungsgemäßen Anordnung 1 zur Führung einer Schiebetür 2.The Figures 3a) to 4c ) show a first preferred embodiment of the arrangement 1 according to the invention for guiding a sliding door 2.

Die Anordnung 1 umfasst ein Schienenprofil 3 und einen relativ zum Schienenprofil 3 in Längsrichtung 4 verfahrbar gelagerten Laufwagen 5, an welchem die Schiebetür 2 befestigbar ist, wobei der Laufwagen 5 einen Wälzkörper 6 und das Schienenprofil 3 eine in Längsrichtung 4 des Schienenprofils 3 verlaufende Lauffläche 7 aufweist, an welcher sich der Wälzkörper 6 abstützt. Dabei ist der Wälzkörper 6 an der Lauffläche 7 quer zur Längsrichtung 4 des Schienenprofils 3 verschiebbar, so dass der Laufwagen 5 um eine im Wesentlichen parallel zur Längsrichtung 4 des Schienenprofils 3 verlaufende Schwenkachse 8 verschwenkbar ist (vergleiche insbesondere die Figuren 4a) bis 4c)).The arrangement 1 comprises a rail profile 3 and a carriage 5 which is mounted movably relative to the rail profile 3 in the longitudinal direction 4 and to which the sliding door 2 can be fastened, the carriage 5 having a rolling element 6 and the rail profile 3 having a running surface 7 running in the longitudinal direction 4 of the rail profile 3 has, on which the rolling body 6 is supported. The rolling element 6 on the running surface 7 can be displaced transversely to the longitudinal direction 4 of the rail profile 3, so that the carriage 5 can be pivoted about a pivot axis 8 which runs essentially parallel to the longitudinal direction 4 of the rail profile 3 (compare in particular Figures 4a) to 4c )).

Das Schienenprofil 3 weist zwei Begrenzungsprofile 10, 11 auf, welche die Lauffläche 7 quer zur Längsrichtung 4 des Schienenprofils 3 begrenzen.The rail profile 3 has two boundary profiles 10, 11, which limit the running surface 7 transversely to the longitudinal direction 4 of the rail profile 3.

Der Wälzkörper 6 ist im Wesentlichen zylinderförmig ausgebildet.The rolling body 6 is essentially cylindrical.

Der Laufwagen 5 weist zwei Lastwälzkörper 14 zur Abstützung des Gewichts einer am Laufwagen 5 befestigten Schiebetüre 2 auf, wobei die Lastwälzkörper 14 im Querschnitt am Umfang eine Nut 15, genauer gesagt eine V-Nut, aufweisen, was besonders gut anhand der Querschnittsdarstellungen der Figuren 4a) bis 4c) ersichtlich ist.The carriage 5 has two load rolling bodies 14 for supporting the weight of a sliding door 2 attached to the carriage 5, the load rolling bodies 14 having a groove 15, more precisely a V-groove, in cross section on the circumference, which is particularly clear from the cross-sectional illustrations Figures 4a) to 4c ) can be seen.

Das Schienenprofil 3 weist eine lastübertragende Lauffläche 16 auf, an welcher sich die Lastwälzkörper 14 abstützen, wobei die lastübertragende Lauffläche 16 im Querschnitt konvex, genauer gesagt kreisförmig, ausgebildet ist.The rail profile 3 has a load-transmitting running surface 16 on which the load rolling bodies 14 are supported, the load-transmitting running surface 16 being convex in cross section, more precisely circular.

Die lastübertragende Lauffläche 16 kann wie im dargestellten Fall an einem vom Schienenprofil 3 gesondert ausgebildeten Einlegeteil 17 ausgebildet sein, wobei das Einlegeteil 17 zylinderförmig ausgebildet ist.The load-transmitting running surface 16 can, as in the case shown, be formed on an insert part 17 that is designed separately from the rail profile 3, the insert part 17 being cylindrical.

Wie insbesondere aus der in der Figur 3c) enthaltenen Explosionsdarstellung hervorgeht, kann der Laufwagen 5 ein Grundgerüst 31 umfassen, an welchem der Wälzkörper 6 und die Lastwälzkörper 14 über Wälzkörperlager 34 drehbar gelagert sind. Weiterhin kann ein Befestigungsprofil 30 zur unmittelbaren oder mittelbaren Befestigung der Schiebetür 2 vorgesehen sein. Zwischen dem Befestigungsprofil 30 und dem Grundgerüst 31 können eine oder mehrere Federn 32 vorgesehen sein. Es bietet sich an, diese auf Führungsbolzen 33 zu lagern.Like in particular from the one in the Figure 3c ) included exploded view, the carriage 5 can include a base frame 31, on which the rolling element 6 and the load rolling elements 14 are rotatably mounted via rolling element bearings 34. Furthermore, a fastening profile 30 can be provided for direct or indirect fastening of the sliding door 2. Between the fastening profile 30 and the base structure 31 one or more springs 32 can be provided. It makes sense to store these on guide pins 33.

Wie insbesondere aus den Figuren 4a) bis 4c) hervorgeht, ist die Lauffläche 7 im Querschnitt konkav ausgebildet. Gleichzeitig weist der Wälzkörper 6 eine Umfangsfläche 9 auf, über welche sich der Wälzkörper 6 bereichsweise an der Lauffläche 7 abstützt, wobei die Umfangsfläche 9 im Querschnitt konvex ausgebildet ist.Like in particular from the Figures 4a) to 4c ) shows, the tread 7 is concave in cross section. At the same time, the rolling body 6 has a peripheral surface 9, via which the rolling body 6 is partially supported on the running surface 7, the peripheral surface 9 being convex in cross section.

Die Figur 4b) zeigt eine Nulllage des Laufwagens 5. Wenn man diese Stellung mit der in der Figur 4c) dargestellte Stellung vergleicht, so kann festgestellt werden, dass das Schienenprofil 3 einen in Längsrichtung 4 verlaufenden und die Lauffläche 7 quer zur Längsrichtung 4 des Schienenprofils 3 begrenzenden Vertikalsteg 10 aufweist, welcher im Wesentlichen senkrecht zur Lauffläche 7 ausgerichtet ist, wobei der Laufwagen 5 derart um die Schwenkachse 8 verschwenkbar ist, dass sich ein Abstand 12 zum Vertikalsteg 10 in einem durch die Schiebetür 2 belasteten Zustand vergrößert.The Figure 4b ) shows a zero position of the carriage 5. If you compare this position with that in the Figure 4c ) compares the position shown, it can be determined that the rail profile 3 has a vertical web 10 which runs in the longitudinal direction 4 and delimits the running surface 7 transversely to the longitudinal direction 4 of the rail profile 3, which is aligned essentially perpendicular to the running surface 7, the carriage 5 being such can be pivoted about the pivot axis 8 so that a distance 12 from the vertical web 10 increases in a state loaded by the sliding door 2.

Gleichzeitig kann es, wie ein Vergleich mit der Figur 4a) zeigt, vorgesehen sein, dass der Laufwagen 5 in die entgegengesetzte Richtung verschwenkbar ist.At the same time it can be like a comparison with the Figure 4a ) shows, it can be provided that the carriage 5 can be pivoted in the opposite direction.

Insgesamt kann es vorgesehen sein, dass der Laufwagen 5 ausgehend von einer Nulllage, welche Laufwagen 5 zumindest in einem durch die Schiebetür 2 unbelasteten Zustand einnimmt, um die Schwenkachse 8 in einem Winkelbereich von +10° und -5° verschwenkbar ist. Der betreffende Winkel ist in der Figur 4b) mit dem Bezugszeichen 23 versehen.Overall, it can be provided that the carriage 5 can be pivoted about the pivot axis 8 in an angular range of +10° and -5°, starting from a zero position, which carriage 5 assumes at least in a state unloaded by the sliding door 2. The angle in question is in the Figure 4b ) provided with the reference number 23.

Wie ebenfalls aus der Figur 4b) hervorgeht, ist der Wälzkörper 6 um eine im Wesentlichen senkrecht zur Schwenkachse 8 verlaufende Drehachse 13 drehbar am Laufwagen 5 gelagert, wobei die Drehachse 13 im Montagzustand im Wesentlichen horizontal ausgerichtet ist.As also from the Figure 4b ) shows, the rolling element 6 is rotatably mounted on the carriage 5 about an axis of rotation 13 that runs essentially perpendicular to the pivot axis 8, the axis of rotation 13 being aligned essentially horizontally in the assembled state.

In Zusammenhang mit der Figur 1 wurde bereits darauf hingewiesen, dass sich die Winkellage des Laufwagens 5 in Bezug auf die Schwenkachse 8 bei einer Bewegung der zwei Türflügel 22 zwischen der Parallelstellung und der Komplanarstellung ändern kann.In connection with the Figure 1 It has already been pointed out that the angular position of the carriage 5 in relation to the pivot axis 8 can change when the two door leaves 22 move between the parallel position and the coplanar position.

Konkret ist die Neigung des Laufwagens 5 gegenüber einer Vertikalstellung in der Komplanarstellung der zwei Türflügel 22 größer als in der Parallelstellung der zwei Türflügel 22.Specifically, the inclination of the carriage 5 relative to a vertical position is greater in the coplanar position of the two door leaves 22 than in the parallel position of the two door leaves 22.

Die Figuren 5a) und 5b) zeigen ein zweites bevorzugtes Ausführungsbeispiel der erfindungsgemäßen Anordnung 1. Die Anordnung 1 umfasst ein Laufwagenscharnier 18, welches mit dem Laufwagen 5 und mit der Schiebetür 2 verbunden oder verbindbar ist, und über welches die Schiebetür 2 gegenüber dem Laufwagen 5 verschwenkbar ist, und zwar um eine in Montagelage vertikale Achse 19 (vergleiche auch Figur 1).The Figures 5a) and 5b ) show a second preferred embodiment of the arrangement 1 according to the invention. The arrangement 1 comprises a carriage hinge 18, which is connected or connectable to the carriage 5 and to the sliding door 2, and via which the sliding door 2 can be pivoted relative to the carriage 5, namely by an axis 19 that is vertical in the assembly position (see also Figure 1 ).

Das Laufwagenscharnier 18 kann wie im dargestellten Fall eine Montageplatte 35 zur Montage an der Schiebetür 2 umfassen. Die Montageplatte 35 ist über Gelenkhebel 36 mit einer Befestigungsschnittstelle 37 gelenkig verbunden, wobei die Befestigungsschnittstelle 37 der Anbindung des Laufwagenscharniers 18 am Laufwagen 5 dient. Das Laufwagenscharnier 18 weist mehrere Gelenkachsen 38, 39, 40 auf.The carriage hinge 18 can, as in the case shown, include a mounting plate 35 for mounting on the sliding door 2. The mounting plate 35 is connected in an articulated manner to a fastening interface 37 via articulated levers 36, the fastening interface 37 serving to connect the carriage hinge 18 to the carriage 5. The carriage hinge 18 has several hinge axes 38, 39, 40.
