Description

Die Erfindung betrifft ein Schiebetürsystem mit wenigstens einer ersten Schiebetür, die zur Anordnung vor einer von der Schiebetür zu verdeckenden Öffnung bestimmt ist und eine obere Schiebetürhalterung sowie eine untere Schiebetürhalterung aufweist, sowie mit einer oberen Führungsschiene zur verschiebbaren Aufnahme der oberen Schiebetürhalterung und einer unteren Führungsschiene zur verschiebbaren Aufnahme der unteren Schiebetürhalterung, wobei beide Führungsschienen sich in Längsrichtung parallel zueinander und parallel zu der abzudeckenden Öffnung erstrecken. Jede Schiebetürhalterung kann als separates, mit der Schiebetür verbundenes Teil ausgeführt sein, sie kann jedoch auch in die Schiebetür integriert sein und beispielsweise lediglich durch den oberen bzw. unteren Rand der Schiebetür gebildet sein.The invention relates to a sliding door system having at least a first sliding door, which is intended to be arranged in front of an opening to be hidden by the sliding door and having an upper sliding door holder and a lower sliding door holder, as well as an upper guide rail for slidably receiving the upper sliding door holder and a lower guide rail slidably receiving the lower sliding door holder, wherein both guide rails extend in the longitudinal direction parallel to each other and parallel to the opening to be covered. Each sliding door holder can be designed as a separate part connected to the sliding door, but it can also be integrated in the sliding door and be formed, for example, only by the upper or lower edge of the sliding door.

Schiebetürsysteme mit verschiebbaren und aushebbaren Türen sind bekannt. Jedoch besteht bei solchen bekannten Schiebetürsystemen das Problem, dass die verwendete Türmechanik eine vollkommene Freigabe der von der Schiebetür zu verdeckenden Öffnung nicht gestattet und/oder das Ausheben der Schiebetür nur an bestimmten Verschiebestellungen der Tür möglich ist.Sliding door systems with sliding and liftable doors are known. However, in such known sliding door systems has the problem that the door mechanism used does not allow a perfect release of the opening to be hidden by the sliding door and / or the lifting of the sliding door is possible only at certain displacement positions of the door.

US 4,575,966 A offenbart ein Schiebefenstersystem, bei dem ein zu verschiebendes Fenster gegen eine von Magneten bereitgestellte Kraft in eine ausgehobene Stellung verlagerbar ist, wobei beim Zurückbewegen des Fensters in die eingesenkte Stellung dieser Widerstand nicht zu überwinden ist. US 4,575,966 discloses a sash window system in which a window to be displaced is displaceable against a force provided by magnets in an excavated position, wherein the backward movement of the window in the recessed position, this resistance is not overcome.

FR 2 760 779 A1 und EP 0 712 989 A1 offenbaren verschiebbare Fassadenelemente. FR 2 760 779 A1 and EP 0 712 989 A1 reveal sliding facade elements.

Der Erfindung liegt die Aufgabe zugrunde, ein verbessertes Schiebetürsystem bereitzustellen, welches gewichtssparender und mechanisch unkomplizierter aufgebaut ist als herkömmliche Schiebetürsysteme und das sich deshalb besonders gut zur Verwendung in einem Flugzeug eignet, insbesondere im Küchenbereich eines Flugzeugs.The invention has for its object to provide an improved sliding door system, which is weight-saving and mechanically uncomplicated constructed as conventional sliding door systems and therefore particularly well suited for use in an aircraft, especially in the kitchen area of an aircraft.

Diese Aufgabe ist erfindungsgemäß durch ein Schiebetürsystem mit den Merkmalen der Patentansprüche 1, 2 und 3 gelöst.This object is achieved by a sliding door system with the features of claims 1, 2 and 3.

Demnach hat jede Führungsschiene eine freie innere Breite, die wenigstens doppelt so groß ist wie die Dicke der Schiebetür. Ferner ist die obere Schiebetürhalterung und die untere Schiebetürhalterung jeweils höchstens halb so breit wie die freie innere Breite jeder Führungsschiene, so dass jede Schiebetür normal zur Ebene der abzudeckenden Öffnung in eine näher an der Öffnung befindliche, eingesenkte Stellung und eine von der Öffnung entferntere, ausgehobene Stellung bewegbar ist. Die eingesenkte Stellung und die ausgehobene Stellung definieren jeweils einen stabilen Zustand der Schiebetür, aus dem die Schiebetür nach Überwindung einer festgelegten, quer zur Verschieberichtung wirkenden Widerstandskraft in den jeweils anderen stabilen Zustand bewegbar ist.Accordingly, each guide rail has a free inner width which is at least twice as large as the thickness of the sliding door. Further, the upper sliding door holder and the lower sliding door holder are each at most half as wide as the free inner width of each guide rail, so that each sliding door normal to the plane of the opening to be covered in a recessed position closer to the opening and a more remote from the opening, excavated Position is movable. The recessed position and the excavated position each define a stable state of the sliding door from which the sliding door after overcoming a fixed, acting transversely to the direction of displacement resistance in the other stable state is movable.

Das erfindungsgemäße Schiebetürsystem weist eine Reihe von Vorteilen auf: Es besteht keine mechanische Kopplung einer Schiebetür mit einer bestimmten abzudeckenden Öffnung, vielmehr stellen die obere Führungsschiene und die untere Führungsschiene, die sich entlang einer Reihe nebeneinander angeordneter, abzudeckender Öffnungen erstrecken können, die einzigen mechanischen Ankopplungspunkte zu der Schiebetür oder den Schiebetüren dar. Ein Verschieben jeder Schiebetür des erfindungsgemäßen Schiebetürsystems ist grundsätzlich sowohl in der eingesenkten Stellung als auch der ausgehobenen Stellung möglich, wenn zum Zeitpunkt einer gewünschten Verschiebung in Verschieberichtung ausreichend Platz besteht. Aufgrund der festgelegten, quer zur Verschieberichtung wirkenden Widerstandskraft ist jede Schiebetür bistabil, d.h. sie kann einen stabilen Zustand in der eingesenkten Stellung und in der ausgehobenen Stellung einnehmen, dauerhafte Zwischenstellungen hingegen werden vermieden. Weil die Art der mechanischen Anbindung beim erfindungsgemäßen Schiebetürsystem unkomplizierter ist, verringert sich das Gesamtgewicht bei gleichzeitiger Erhöhung der Betriebssicherheit deutlich, was insbesondere für einen Einsatz eines solchen Schiebetürsystems in einem Flugzeug von großen Vorteil ist. Zudem wirkt das erfindungsgemäße Schiebetürsystem sehr aufgeräumt und damit elegant.The sliding door system according to the invention has a number of advantages: there is no mechanical coupling of a sliding door with a certain opening to be covered, but the upper guide rail and the lower guide rail, which can extend along a series of juxtaposed to be covered openings, the only mechanical Ankopplungspunkte to the sliding door or the sliding doors. Moving each sliding door of the sliding door system according to the invention is basically possible both in the depressed position and the excavated position, if there is sufficient space in the direction of displacement at the time of a desired shift. Due to the fixed resistance force acting transversely to the direction of displacement, each sliding door is bistable, i. It can assume a stable state in the lowered position and in the raised position, permanent intermediate positions, however, are avoided. Because the nature of the mechanical connection in the sliding door system according to the invention is less complicated, the total weight is significantly reduced while at the same time increasing operational reliability, which is of great advantage, in particular, for using such a sliding door system in an aircraft. In addition, the sliding door system according to the invention acts very tidy and thus elegant.

Gemäß einer ersten Ausgestaltung des erfindungsgemäßen Schiebetürsystems wird die festgelegte, quer zur Verschieberichtung wirkende Widerstandskraft erzeugt, indem längs der Mittellinie der unteren Führungsschiene und der oberen Führungsschiene jeweils eine Reihe erster Magnete angeordnet ist, und in der unteren Schiebetürhalterung und in der oberen Schiebetürhalterung jeweils eine Reihe zweiter Magnete so angeordnet ist, dass zwischen der Reihe erster Magnete und der Reihe zweiter Magnete Abstoßungskräfte wirken. Diese Abstoßungskräfte sind aufgrund der mittigen Anordnung der ersten Magnete in der unteren bzw. oberen Führungsschiene dann am größten, wenn eine Schiebetür sich genau zwischen ihren beiden stabilen Zuständen befindet. Die Schiebetür schnappt also beim Bewegen aus dem einen stabilen Zustand, z.B. der eingesenkten Stellung, nach Überwinden der durch die zwischen den Magneten wirkenden Abstoßungskräfte hervorgerufenen Widerstandskraft quasi in den anderen stabilen Zustand, hier in die ausgehobene Stellung, und wird durch die genannten Abstoßungskräfte in den jeweiligen stabilen Zustand gedrängt. Dabei sind die im stabilen Zustand wirkenden Abstoßungskräfte aber nicht so groß, dass sie ein Verschieben der Schiebetür spürbar behindern.According to a first embodiment of the sliding door system according to the invention, the fixed resistance force acting transversely to the direction of displacement is generated by arranging a series of first magnets along the center line of the lower guide rail and the upper guide rail, and a row in the lower sliding door support and in the upper sliding door support, respectively second magnets is arranged so that between the series of first magnets and the series of second magnets repulsive forces act. These repulsive forces are greatest due to the central location of the first magnets in the lower and upper guide rails, respectively, when a sliding door is located exactly between its two stable states. The sliding door thus snaps when moving from the one stable state, for example, the lowered position, after overcoming the resistance force caused by the repulsive forces acting between the magnets quasi in the other stable state, here in the excavated position, and is characterized by the repulsive forces in the respective stable state urged. However, the repulsive forces acting in the stable state are not so great that they noticeably hinder a sliding movement of the sliding door.

Gemäß einer anderen Ausgestaltung des erfindungsgemäßen Schiebetürsystems wird die festgelegte, quer zur Verschieberichtung wirkende Widerstandskraft hervorgerufen, indem längs der Mittellinie der unteren Führungsschiene eine Reihe erster Magnete angeordnet ist und in der unteren Schiebetürhalterung eine Reihe zweiter Magnete so angeordnet ist, dass zwischen der Reihe erster Magnete und der Reihe zweiter Magnete Abstoßungskräfte wirken, und indem längs der oberen Führungsschiene eine erste Reihe dritter Magnete an Orten angeordnet ist, die der oberen Schiebetürhalterung benachbart sind, wenn die Schiebetür sich in der eingesenkten Stellung befindet, und eine zweite Reihe dritter Magnete an Orten angeordnet ist, die der oberen Schiebetürhalterung benachbart sind, wenn die Schiebetür sich in der ausgehobenen Stellung befindet, und in der oberen Schiebetürhalterung eine Reihe zweiter Magnete so angeordnet ist, dass zwischen den Reihen dritter Magnete und der Reihe zweiter Magnete Anziehungskräfte wirken.According to another embodiment of the sliding door system according to the invention, the fixed, acting transversely to the direction of displacement resistance is caused by a row of first magnets along the center line of the lower guide rail is arranged and in the lower sliding door holder a series of second magnets is arranged so that between the series of first magnets and the series of second magnets are repulsive forces, and along the upper guide rail are disposed a first row of third magnets in locations adjacent to the upper sliding door support when the sliding door is in the depressed position and a second row of third magnets disposed in locations are adjacent to the upper sliding door holder when the sliding door is in the raised position, and in the upper sliding door holder a series of second magnets is arranged so that between the rows of third magnets and the series second Magnets of attraction act.

Bei der vorgenannten Ausgestaltung ist die Funktion der ersten und zweiten Magnete wie bei der ersten Ausgestaltung beschrieben, im Bereich der oberen Schiebetürhalterung und der oberen Führungsschiene hingegen werden durch die zwei Reihen dritter Magnete magnetische Anziehungskräfte erzeugt, die besonders stark in den zwei stabilen Zuständen der Schiebetür wirken, d.h. in der eingesenkten Stellung und in der ausgehobenen Stellung der Schiebetür. Diese Anziehungskräfte helfen beim Bewegen einer Schiebetür aus ihrem einen stabilen Zustand in den anderen stabilen Zustand, indem sie die betreffende Schiebetür etwas anzuheben trachten, wodurch die Reibung insbesondere zwischen der unteren Schiebetürhalterung und der unteren Führungsschiene vermindert und die angesprochene Bewegung erleichtert wird. Zudem sorgen diese Anziehungskräfte für eine besonders deutliche Ausprägung des bistabilen Zustands, weil sie in den beiden stabilen Zuständen der Schiebetür am stärksten sind.In the aforementioned embodiment, the function of the first and second magnets as described in the first embodiment, in the region of the upper sliding door holder and the upper guide rail, however, are generated by the two rows of third magnetic magnetic attraction forces, which are particularly strong in the two stable states of the sliding door act, ie in the lowered position and in the raised position of the sliding door. These forces of attraction assist in moving a sliding door from its one stable state to the other stable state by attempting to lift the sliding door in question, thereby reducing friction between the lower sliding door support and the lower guide rail, in particular, and facilitating the aforementioned movement. In addition, these attractions provide a particularly clear expression of the bistable state because they are strongest in the two stable states of the sliding door.

Gemäß einer dritten Ausgestaltung des erfindungsgemäßen Schiebetürsystems wird die festgelegte, quer zur Verschieberichtung der Schiebetür wirkende Widerstandskraft hervorgerufen, indem längs der unteren Führungsschiene und der oberen Führungsschiene jeweils eine Reihe erster Magnete an Orten angeordnet ist, die der unteren Schiebetürhalterung bzw. der oberen Schiebetürhalterung benachbart sind, wenn die Schiebetür sich in der eingesenkten Stellung befindet, und jeweils eine zweite Reihe erster Magnete an Orten angeordnet ist, die der unteren Schiebetürhalterung bzw. der oberen Schiebetürhalterung benachbart sind, wenn die Schiebetür sich in der ausgehobenen Stellung befindet, und indem sowohl in der unteren Schiebetürhalterung als auch der oberen Schiebetürhalterung jeweils eine Reihe zweiter Magnete so angeordnet ist, dass zwischen den Reihen erster Magnete und der Reihe zweiter Magnete Anziehungskräfte wirken.According to a third embodiment of the sliding door system according to the invention, the fixed, acting transversely to the direction of sliding door resistance force is caused by along the lower guide rail and the upper guide rail respectively a series of first magnets is disposed at locations adjacent to the lower sliding door holder and the upper sliding door holder when the sliding door is in the lowered position and one each second row of first magnets are disposed at locations adjacent to the lower sliding door bracket and the upper sliding door bracket, respectively, when the sliding door is in the excavated position, and arranging a row of second magnets respectively in both the lower sliding door bracket and the upper sliding door bracket is that attraction forces act between the rows of first magnets and the row of second magnets.

Diese dritte Ausgestaltung wendet das Funktionsprinzip, das bei der zweiten Ausgestaltung nur hinsichtlich der oberen Führungsschiene zum Einsatz kam, auch bei der unteren Führungsschiene an. Im Gegensatz zur ersten Ausgestaltung, bei der die festgelegte, quer zur Verschieberichtung wirkende Widerstandskraft in der Mitte zwischen den beiden stabilen Zuständen einer Schiebetür am größten ist, nimmt diese Widerstandskraft bei der dritten Ausgestaltung ihr Maximum in den beiden stabilen Zuständen selbst an.This third embodiment applies the principle of operation, which was used in the second embodiment only with respect to the upper guide rail, even in the lower guide rail. In contrast to the first embodiment, in which the fixed resistance force acting transversely to the displacement direction is greatest in the middle between the two stable states of a sliding door, this resistance force in the third embodiment assumes its maximum in the two stable states itself.

Bei den drei zuvor genannten Ausgestaltungen des erfindungsgemäßen Schiebetürsystems können die Magnete Permanentmagnete sein. Die Permanentmagnete können als Stabmagnete ausgebildet und quer zur Erstreckung der jeweiligen Führungsschiene in oder auf derselben so angeordnet, dass beispielsweise ihr Minuspol sich im Bereich der Mitte der Führungsschiene befindet. Der zugehörige Pluspol eines Magneten ist dann im Randbereich der Führungsschiene angeordnet. In den Schiebetürhalterungen sind als Stabmagnete ausgebildete Permanentmagnete beim gewählten Beispiel hingegen so angeordnet, dass ihre Minuspole nach unten bzw. oben, d.h. zu den Minuspolen in den Führungsschienen zeigen. Wenn die in den Führungsschienen angeordneten Permanentmagnete so angeordnet sind, dass die Pluspole abwechselnd nach links und nach rechts zeigen, dann können zusätzlich zu den sich in der Mittelstellung zwischen den stabilen Zuständen ergebenden Abstoßungskräften auch Anziehungskräfte genutzt werden, die in den beiden stabilen Endstellungen der Schiebetür wirken.In the three aforementioned embodiments of the sliding door system according to the invention, the magnets may be permanent magnets. The permanent magnets may be formed as bar magnets and arranged transversely to the extent of the respective guide rail in or on the same so that, for example, their negative pole is located in the region of the center of the guide rail. The associated positive pole of a magnet is then arranged in the edge region of the guide rail. On the other hand, in the sliding door mounts, permanent magnets formed as bar magnets are arranged in the selected example so that their negative poles are directed downwards or upwards, i. to show the negative poles in the guide rails. If the permanent magnets arranged in the guide rails are arranged such that the positive poles alternately point to the left and to the right, then in addition to the repulsive forces resulting in the middle position between the stable states, attractive forces can also be utilized in the two stable end positions of the sliding door Act.

Anstelle von Permanentmagneten können auch elektrisch angesteuerte Spulenmagnete zum Einsatz kommen. Solche Spulenmagnete bieten den Vorteil, dass ihre Polarität sich durch eine Umkehr des durch sie fließenden Stroms umkehren lässt.Instead of permanent magnets and electrically driven coil magnets can be used. Such coil magnets offer the advantage that their polarity can be reversed by reversing the current flowing through them.

Die obere Führungsschiene und/oder die untere Führungsschiene ist vorzugsweise im Querschnitt U-förmig. Dies ermöglich es, die Magnete, insbesondere die Spulenmagnete, in oder an den Schenkeln des U-förmigen Querschnitts anzuordnen. Gemäß einer bevorzugten Ausführungsform des erfindungsgemäßen Schiebetürsystems weisen die untere Führungsschiene und die obere Führungsschiene einen U-förmigen Querschnitt mit zwei Schenkeln auf, von denen ein Schenkel der Ebene der abzudeckenden Öffnung benachbart ist und ein Schenkel von der Ebene der abzudeckenden Öffnung weiter entfernt ist. Längs des Schenkels, der der Ebene der abzudeckenden Öffnung benachbart ist, ist die erste Reihe erster Magnete angeordnet. Längs des Schenkels, der von der Ebene der abzudeckenden Öffnung weiter entfernt ist, ist die zweite Reihe erster Magnete angeordnet. Die ersten Magnete sind bei dieser Ausführungsform elektrisch angesteuerte, in ihrer Polarität umkehrbare Spulenmagnete, so dass die Schiebetür durch entsprechende elektrische Ansteuerung der Spulenmagnete aus z.B. der eingesenkten Stellung in die ausgehobene Stellung und zurück bewegt werden kann. Dies ist einfach dadurch zu erreichen, dass die ersten Magnete so angesteuert werden, dass zwischen der ersten Reihe erster Magnete in der Führungsschiene und der Reihe zweiter Magnete in der Schiebetürhalterung Abstoßungskräfte und zwischen der zweiten Reihe erster Magnete in der Führungsschiene und der Reihe zweiter Magnete in der Schiebetürhalterung Anziehungskräfte wirken (Bewegung der Schiebetür aus der eingesenkten Stellung in die ausgehobene Stellung) bzw. so angesteuert werden, dass zwischen der zweiten Reihe erster Magnete (in der Führungsschiene) und der Reihe zweiter Magnete (in der Schiebetürhalterung) Abstoßungskräfte und zwischen der ersten Reihe erster Magnete und der Reihe zweiter Magnete Anziehungskräfte wirken (Bewegung der Schiebetür von der ausgehobenen Stellung in die eingesenkte Stellung).The upper guide rail and / or the lower guide rail is preferably U-shaped in cross section. This makes it possible to arrange the magnets, in particular the coil magnets, in or on the legs of the U-shaped cross section. According to According to a preferred embodiment of the sliding door system according to the invention, the lower guide rail and the upper guide rail have a U-shaped cross section with two legs, one leg of which is adjacent to the plane of the opening to be covered and one leg is further away from the plane of the opening to be covered. Along the leg, which is adjacent to the plane of the opening to be covered, the first row of first magnets is arranged. Along the leg, which is further away from the plane of the opening to be covered, the second row of first magnets is arranged. The first magnets are electrically driven in this embodiment, reversible in polarity coil magnets, so that the sliding door can be moved by appropriate electrical control of the coil magnets from eg the depressed position in the excavated position and back. This can be achieved simply by controlling the first magnets such that repulsion forces exist between the first row of first magnets in the guide rail and the row of second magnets in the sliding door holder and between the second row of first magnets in the guide rail and the row of second magnets in The sliding door support attraction acts (movement of the sliding door from the depressed position to the excavated position) or be controlled so that between the second row of first magnets (in the guide rail) and the series of second magnets (in the sliding door holder) repulsive forces and between the first Series of first magnets and the series of second magnets attraction forces (movement of the sliding door from the raised position to the lowered position).

Bei allen Ausgestaltungen des erfindungsgemäßen Schiebetürsystems sind vorzugsweise mehrere abzudeckende Öffnungen in einer Reihe nebeneinander angeordnet und die obere Führungsschiene sowie die untere Führungsschiene erstreckt sich jeweils über die Gesamtlänge aller zu verdeckender Öffnungen, wobei in den Führungsschienen mehrere Schiebetüren zur Abdeckung mehrerer oder aller vorhandener Öffnungen verschiebbar aufgenommen sind. Ein großer Vorteil des erfindungsgemäßen Schiebetürsystems besteht dabei darin, dass jede Schiebetür entlang der Gesamterstreckung der oberen und unteren Führungsschienen frei verschiebbar ist, so dass zur Abdeckung einer bestimmten Öffnung jede beliebige Schiebetür verwendet werden kann. Die Verschiebebewegung jeder Schiebetür kann ein Gleitvorgang oder ein Rollvorgang sein, je nach konstruktiver Ausführung der Schiebetür.In all embodiments of the sliding door system according to the invention a plurality of openings to be covered are preferably arranged side by side in a row and the upper guide rail and the lower guide rail extends over the total length of all openings to be concealed, wherein in the guide rails several sliding slidably received to cover several or all existing openings are. A major advantage of the sliding door system according to the invention consists in the fact that each sliding door along the entire extension of the upper and lower guide rails is freely displaced so that any sliding door can be used to cover a specific opening. The sliding movement of each sliding door may be a sliding operation or a rolling operation, depending on the structural design of the sliding door.

Bei Ausführungsformen mit mehreren nebeneinander angeordneten Öffnungen können die obere Führungsschiene und die untere Führungsschiene einstückig ausgebildet sein, vorteilhaft sind die obere Führungsschiene und die untere Führungsschiene jedoch jeweils aus mehreren, sich aneinander anschließenden Führungsschienenabschnitten gebildet.In embodiments having a plurality of juxtaposed openings, the upper guide rail and the lower guide rail may be formed integrally However, advantageously, the upper guide rail and the lower guide rail are each formed from a plurality of adjoining guide rail sections.

Ferner ist bei bevorzugten Ausführungsformen des erfindungsgemäßen Schiebetürsystems jede Schiebetür in ihrer eingesenkten Stellung verriegelbar. Durch eine solche Verriegelung kann beispielsweise sichergestellt werden, dass jede Schiebetür ihre eingesenkte Stellung auch unter widrigen Umständen zuverlässig beibehält, etwa beim Auftreten starker auf die Schiebetüren wirkender Kräfte, wie sie im Flugbetrieb durch Luftturbulenzen hervorgerufen werden können.Furthermore, in preferred embodiments of the sliding door system according to the invention, each sliding door can be locked in its lowered position. By such a lock can be ensured, for example, that each sliding door reliably retains its lowered position even under adverse circumstances, such as the occurrence of strong forces acting on the sliding doors forces, such as those caused by air turbulence in flight.

Ein Ausführungsbeispiel der Erfindung wird im Folgenden anhand der beigefügten, schematischen Figuren näher erläutert. Es zeigt:

an embodiment of a sliding door system in cross section, wherein in FIG. 1 a sliding door is shown both in a lowered position and in a raised position,

Figur 1 zeigt schematisch ein Ausführungsbeispiel eines allgemein mit 10 bezeichneten Schiebetürsystems, wobei in der Figur lediglich der für die Funktion des Systems interessante obere und untere Bereich wiedergegeben ist, der mittlere Abschnitt hingegen weggelassen worden ist. FIG. 1 shows schematically an embodiment of a generally designated 10 sliding door system, wherein in the figure, only the interesting for the function of the system upper and lower area is reproduced, the middle section has been omitted, however.

Das Schiebetürsystem 10 weist wenigstens eine Schiebetür 12 auf, die dazu gedacht ist, je nach Verschiebestellung eine Öffnung 14 abzudecken bzw. zu verdecken. Bei der Öffnung 14 kann es sich beispielsweise um die vordere Öffnung eines Schrankfachs oder ähnliches handeln.The sliding door system 10 has at least one sliding door 12 which is intended to cover or cover an opening 14 depending on the displacement position. The opening 14 may be, for example, the front opening of a cabinet compartment or the like.

Die Schiebetür 12 umfasst ein Türblatt 16, an dem eine obere Schiebetürhalterung 18 und eine untere Schiebetürhalterung 20 befestigt sind. Damit die Schiebetür 12 entlang der Verschieberichtung verschoben werden kann (in Figur 1 verläuft diese Verschieberichtung normal zur Papierebene), ist die obere Schiebetürhalterung 18 in einer oberen Führungsschiene 22 und die untere Schiebetürhalterung 20 in einer unteren Führungsschiene 24 aufgenommen. Beide Führungsschienen 22, 24 haben im dargestellten Ausführungsbeispiel einen im Wesentlichen U-förmigen Querschnitt mit der seitlichen Führung dienenden Schenkeln, von denen ein Schenkel 26 der Ebene der abzudeckenden Öffnung 14 benachbart ist, während der andere Schenkel 28 von der abzudeckenden Öffnung 14 weiter entfernt ist. Die Führungsschienen 22, 24 verlaufen parallel zueinander und parallel zur Öffnung 14.The sliding door 12 includes a door panel 16 to which an upper sliding door bracket 18 and a lower sliding door bracket 20 are attached. Thus, the sliding door 12 can be moved along the direction of displacement (in FIG. 1 If this displacement direction is normal to the plane of the paper), the upper sliding door holder 18 is accommodated in an upper guide rail 22 and the lower sliding door holder 20 is received in a lower guide rail 24. Both guide rails 22, 24 have in the illustrated embodiment has a substantially U-shaped cross-section with the lateral guide serving legs, of which one leg 26 of the plane of the opening to be covered 14 is adjacent, while the other leg 28 is further away from the opening 14 to be covered. The guide rails 22, 24 are parallel to each other and parallel to the opening 14th

Die bzw. jede Schiebetür 12 des Schiebetürsystems 10 lässt sich nicht nur in der genannten Richtung verschieben, sondern auch in einer Richtung normal zur Ebene der abzudeckenden Öffnung aus einer näher an der Öffnung 14 befindlichen, eingesenkten Stellung in eine von der Öffnung entferntere, ausgehobene Stellung und zurück bewegen, wie in Figur 1 durch den Doppelpfeil Z symbolisiert. Dabei stellt die in Figur 1 rechts wiedergegebene Schiebetür 12 die ausgehobene Stellung dar, während die in Figur 1 links wiedergegebene Schiebetür 12 die eingesenkte Stellung repräsentiert.The or each sliding door 12 of the sliding door system 10 can be moved not only in said direction, but also in a direction normal to the plane of the opening to be covered from a depressed position closer to the opening 14 to a more remote from the opening, excavated position and move back, as in FIG. 1 symbolized by the double arrow Z In doing so, the in FIG. 1 Right sliding door 12 shown the excavated position, while the in FIG. 1 left sliding door 12 represents the lowered position.

Um die Bewegung der Schiebetür 12 aus der eingesenkten Stellung in die ausgehobene Stellung und zurück zu ermöglichen, hat jede Führungsschiene 22, 24 eine freie innere Breite x, die wenigstens doppelt so groß ist wie die Dicke der Schiebetür 12, genauer ihres Türblatts 16. Ferner ist jede Schiebetürhalterung 18, 20 höchstens halb so breit wie die freie innere Breite x jeder Führungsschiene 22, 24.In order to facilitate the movement of the sliding door 12 from the recessed position to the raised position and back, each guide rail 22, 24 has a free inner width x that is at least twice the thickness of the sliding door 12, more particularly its door panel 16. Further is any sliding door holder 18, 20 at most half as wide as the free inner width x of each guide rail 22, 24th

Bei einer Bewegung der Schiebetür 12 aus der eingesenkten Stellung in die ausgehobene Stellung und zurück muss eine festgelegte, quer zur Verschieberichtung der Schiebetür wirkende Widerstandskraft überwunden werden, die dazu führt, dass die eingesenkte Stellung der Schiebetür 12 und die ausgehobene Stellung der Schiebetür 12 jeweils einen stabilen Zustand darstellen, in dem die Schiebetür 12 verbleibt, wenn keine zur Überwindung der festgelegten Widerstandskraft ausreichenden Kräfte auf sie wirken.In a movement of the sliding door 12 from the depressed position to the excavated position and back a fixed, acting transversely to the direction of sliding door resistance force must be overcome, which causes the recessed position of the sliding door 12 and the excavated position of the sliding door 12 each one represent stable state in which the sliding door 12 remains when there are no sufficient forces to overcome the specified resistance force on them.

Bei dem in Figur 1 dargestellten Ausführungsbeispiel ist diese Widerstandskraft eine magnetische Widerstandskraft. Zur Erzeugung dieser magnetischen Widerstandskraft ist längs der Mittellinie der unteren Führungsschiene 24 eine Reihe erster Magnete 30 angeordnet und in der unteren Schiebetürhalterung 20 ist eine Reihe zweiter Magnete 32 so angeordnet, dass zwischen der Reihe erster Magnete 30 und der Reihe zweiter Magnete 32 Abstoßungskräfte wirken, d.h. die einzelnen Magnete 30 und 32 sind so angeordnet, dass gleichartige und sich daher abstoßende magnetische Pole einander zugewandt sind (siehe auch Figur 2). Bei einer Bewegung der Schiebetür 12 in Z-Richtung kommt es auf diese Weise zu dem in Figur 3 dargestellten Verlauf der magnetischen Widerstandskraft, die ihr Maximum genau in der Mitte des Verschiebeweges x hat, da dort die einander zugewandten, gleichnamigen Pole der ersten Magnete 30 und der zweiten Magnete 32 sich genau gegenüberliegen. Zur eingesenkten Stellung (Fig. 2a) hin und auch zur ausgehobenen Stellung (Fig. 2b) hin nimmt die magnetische Widerstandskraft kontinuierlich ab und kann sich sogar in eine leichte Anziehungskraft ändern, insbesondere dann, wenn der ungleichnamige Pol der ersten Magnete 30 sich links bzw. rechts von der Mittellinie der unteren Führungsschiene 24 befindet.At the in FIG. 1 illustrated embodiment, this resistance force is a magnetic resistance. To generate this magnetic resistance force, a series of first magnets 30 are disposed along the center line of the lower guide rail 24, and a series of second magnets 32 are disposed in the lower sliding door holder 20 such that repulsion forces act between the series of first magnets 30 and the series of second magnets 32. ie the individual magnets 30 and 32 are arranged so that similar and therefore repelling magnetic poles face each other (see also FIG. 2 ). In a movement of the sliding door 12 in the Z direction, it comes in this way to the in FIG. 3 shown course of the magnetic resistance force, which has its maximum exactly in the middle of the displacement path x, since there the mutually facing, like poles the first magnets 30 and the second magnets 32 are exactly opposite. To the lowered position ( Fig. 2a ) and also to the excavated position ( Fig. 2b ), the magnetic resistance decreases continuously and may even change to a slight attraction, especially when the unlike pole of the first magnets 30 is located to the left or right of the center line of the lower guide rail 24.

Längs der oberen Führungsschiene 22 ist im gezeigten Ausführungsbeispiel eine erste Reihe dritter Magnete 34 an einer Stelle angeordnet, die der oberen Schiebetürhalterung 18 benachbart ist, z.B. im Wesentlichen gegenüber liegt, wenn die Schiebetür 12 sich in ihrer eingesenkten Stellung befindet. Eine zweite Reihe dritter Magnete 36 ist in der oberen Führungsschiene 22 an einer Stelle angeordnet, die der oberen Schiebetürhalterung 18 benachbart ist, z.B. im Wesentlichen gegenüber liegt, wenn die Schiebetür 12 sich in ihrer ausgehobenen Stellung befindet. Zum Zusammenwirken mit der ersten Reihe dritter Magnete 34 und der zweiten Reihe dritter Magnete 36 ist in der oberen Schiebetürhalterung 18 eine weitere Reihe zweiter Magnete 32 so angeordnet, dass zwischen den Reihen dritter Magnete 34, 36 und der Reihe zweiter Magnete 32 Anziehungskräfte wirken, d.h. die zweiten Magnete 32 sind so angeordnet, dass ihr einer magnetischer Pol dem ungleichnamigen Pol der dritten Magnete 34, 36 zugewandt ist.Along the upper guide rail 22, in the illustrated embodiment, a first row of third magnets 34 is disposed at a location adjacent to the upper sliding door bracket 18, e.g. is substantially opposite, when the sliding door 12 is in its depressed position. A second row of third magnets 36 is disposed in the upper guide rail 22 at a location adjacent to the upper sliding door bracket 18, e.g. is substantially opposite, when the sliding door 12 is in its raised position. To co-operate with the first row of third magnets 34 and the second row of third magnets 36, a further row of second magnets 32 is disposed in the upper sliding door support 18 such that attraction forces act between the rows of third magnets 34, 36 and the row of second magnets 32, i. the second magnets 32 are arranged such that they face a magnetic pole of the unlike pole of the third magnets 34, 36.

In der eingesenkten Stellung und der ausgehobenen Stellung der Schiebetür 12 wirken somit zwischen der ersten Reihe dritter Magnete 34 und den in der oberen Schiebetürhalterung 18 angeordneten zweiten Magneten 32 bzw. zwischen letzteren und der zweiten Reihe dritter Magnete 36 Anziehungskräfte, die bei einer Bewegung der Schiebetür 12 aus der eingesenkten Stellung in die ausgehobene Stellung und zurück überwunden werden müssen und die sich der magnetischen Widerstandskraft gemäß Figur 3 überlagern. Zum anderen trachten diese Anziehungskräfte danach, die Schiebetür 12 etwas aus der unteren Führungsschiene 24 anzuheben, was die Reibung der unteren Schiebetürhalterung 20 in der unteren Führungsschiene 24 vermindert und die Bewegung der Schiebetür 12 sowohl in Verschieberichtung als auch in Z-Richtung erleichtert.In the depressed position and the raised position of the sliding door 12 thus act between the first row of third magnets 34 and arranged in the upper sliding door holder 18 second magnet 32 and between the latter and the second row of third magnets 36 attraction forces, the movement of the sliding door 12 must be overcome from the depressed position in the excavated position and back and the magnetic resistance according to FIG. 3 overlap. On the other hand, these attractive forces tend to lift the sliding door 12 somewhat out of the lower guide rail 24, which reduces the friction of the lower sliding door bracket 20 in the lower guide rail 24 and facilitates the movement of the sliding door 12 in both the shift direction and the Z direction.

Die Magnete 30, 32, 34 und 36 können als Permanentmagnete ausgebildet sein oder können elektrisch angesteuerte Spulenmagnete sein. Kombinationen beider Magnetarten sind ebenfalls denkbar, beispielsweise können die in den Schiebetürhalterungen 18, 20 befindlichen Magnete Permanentmagnete sein, während die in den Führungsschienen 22, 24 befindlichen Magnete elektrisch ansteuerbare Spulenmagnete sind.The magnets 30, 32, 34 and 36 may be formed as permanent magnets or may be electrically driven coil magnets. Combinations of both types of magnets are also conceivable, for example, located in the sliding door mounts 18, 20 magnets may be permanent magnets, while in the Guide rails 22, 24 located magnets are electrically controllable coil magnets.

Figur 4 zeigt in perspektivischer Darstellung den oberen Bereich einer Schiebetür 12 mit der oberen Schiebetürhalterung 18, in der die zweiten Magnete 32 in Gruppen von jeweils drei Magneten jeweils gleich ausgerichtet angeordnet sind. Insgesamt befinden sich bei diesem Ausführungsbeispiel 36 zweite Magnete 32 in der oberen Schiebetürhalterung 18, jedoch hängt die Anzahl zweiter Magnete 32 von der Größe und dem Gewicht der Schiebetür 12 ab und wird je nach Anwendungsfall so gewählt, dass sich geeignete Abstoßungs- und/oder Anziehungskräfte ergeben. FIG. 4 shows in perspective the upper portion of a sliding door 12 with the upper sliding door holder 18, in which the second magnets 32 are arranged in groups of three magnets in each case aligned the same. Overall, 36 second magnets 32 are in the upper sliding door bracket 18 in this embodiment, but the number of second magnets 32 depends on the size and weight of the sliding door 12 and is chosen depending on the application so that suitable repulsion and / or attractive forces result.

In Figur 4 ist ferner ein allgemein mit 38 bezeichneter Türverriegelungsmechanismus zu sehen, der im Wesentlichen aus einem in der Türebene verschiebbar gelagerten Rahmen oder Grundkörper 40 besteht, an dem zwei Verriegelungsklinken 42 befestigt sind, die durch die obere Schiebetürhalterung 18 hindurch oder an ihr vorbei in zugehörige, nicht dargestellte Schlitze eingreifen können, welche in der oberen Führungsschiene 22 ausgebildet sind. Bei ausgefahrenen, d.h. in die genannten Schlitze eingreifenden Verriegelungsklinken 42 ist die Schiebetür 12 gegen eine unbeabsichtigte Öffnung verriegelt, im eingefahrenen Zustand der Verriegelungsklinken 42 hingegen zur Verschiebung in Verschieberichtung und zur Bewegung in Z-Richtung frei. Ein gleichartiger Türverriegelungsmechanismus 38 kann auch im unteren Teil der Schiebetür 12 vorhanden sein und mit der unteren Führungsschiene 24 zusammenwirken.In FIG. 4 Further, there is shown a door locking mechanism, generally indicated at 38, consisting essentially of a frame or base 40 slidably mounted in the door plane, to which are attached two locking pawls 42 passing through or past the upper sliding door support 18 shown slots can be engaged, which are formed in the upper guide rail 22. When extended, ie in the said slots engaging locking pawls 42, the sliding door 12 is locked against unintentional opening, in the retracted state of the locking pawls 42, however, free to move in the direction of displacement and movement in the Z direction. A similar door lock mechanism 38 may also be present in the lower part of the sliding door 12 and cooperate with the lower guide rail 24.

Wie sich anhand von Figur 1 gut erkennen lässt, kann eine sich in ihrer ausgehobenen Stellung befindliche Schiebetür 12 an einer anderen, sich in ihrer eingesenkten Stellung befindlichen Schiebetür 12 vorbeigeschoben werden. Auf diese Weise entfällt bei mehreren nebeneinander angeordneten Öffnungen 14 und mehreren Schiebetüren 12 eine feste Zuordnung einer bestimmten Schiebetür 12 zu einer bestimmten Öffnung 14. Stattdessen kann jede Schiebetür 12 zur Abdeckung jeder beliebigen Öffnung 14 verwendet werden.As reflected by FIG. 1 can be seen well, a sliding door located in its excavated position 12 can be pushed past at another, located in its depressed position sliding door 12. In this way eliminates a plurality of juxtaposed openings 14 and a plurality of sliding doors 12, a fixed assignment of a particular sliding door 12 to a particular opening 14. Instead, each sliding door 12 can be used to cover any opening 14.
