Description

Die vorliegende Erfindung betrifft ein Möbel mit einem elektromechanischen Verschlusssystem für ein Möbel mit mindestens zwei auf parallelen Laufbahnen verfahrbaren und zumindest einen Teilbereich eines Möbelkorpus schließenden Schiebetüren, gemäß dem Oberbegriff des Anspruchs 1.The present invention relates to a piece of furniture having an electromechanical locking system for a piece of furniture with at least two sliding doors that can be moved on parallel tracks and that close at least one subarea of a furniture body, according to the preamble of claim 1.

Ein gattungsgemäßes Verschlusssystem für solche Schiebetürenmöbel ist beispielsweise aus der DE 103 23 696 A1 bekannt. Bei dem dort offenbarten Schiebetürenmöbel und Schiebetürenschließsystem sind in zwei parallelen Verschiebeebenen verschiebbare geführte Schiebetüren in Laufschubprofilen aufgenommen, die auf jeweiligen Laufbahnen verfahrbar sind. In diesen Laufschubprofilen sind Griffstücke vorgesehen, die sich in einer Schließposition der Schiebetüren senkrecht zur Verschieberichtung betrachtet überdecken.A generic closure system for such sliding door furniture is for example from the DE 103 23 696 A1 known. In the sliding door furniture and sliding door closing system disclosed therein, slidable guided sliding doors are accommodated in running-thrust profiles which can be moved on respective raceways in two parallel sliding planes. In these operating thrust profiles grips are provided, which overlap considered in a closed position of the sliding doors perpendicular to the direction of displacement.

Zur Aushebesicherung dieser Schiebetüren sind die einander zugewandten Seiten der Griffstücke nach Art einer Nut-Feder-Verbindung ausgestaltet, so dass ein Aushebeln einer der Schiebetüren im Bereich der Griffstelle durch den Eingriff der beiden Griffstücke miteinander verhindert wird.To lift this sliding doors, the mutually facing sides of the grips are designed in the manner of a tongue and groove connection, so that a levering one of the sliding doors in the region of the grip is prevented by the engagement of the two grips with each other.

Nachteilig bei dem aus dem Stand der Technik bekannten Verschlusssystem ist, dass zur Bewerkstelligung dieser Aushebesicherung die Türen mit unterschiedlichen Bauteilen ausgestattet werden müssen, um das funktionsgemäße Zusammenwirken der Griffstücke gewährleisten zu können.A disadvantage of the closure system known from the prior art that the doors must be equipped with different components to accomplish this Aushebsicherung to ensure the proper interaction of the grips can.

Des Weiteren müssen zur Unterbringung des Verschlusssystems Ausnehmungen im Möbelkorpus vorgenommen werden, was insbesondere die Nachrüstbarkeit solcher Verschlusssysteme erschwert oder sogar verhindert. Bei dem in der DE 103 23 696 A1 offenbarten Schiebetürmöbel ist das Verschlusssystem unterhalb der Laufschuhprofile montiert.Furthermore, recesses must be made in the furniture carcass for accommodating the closure system, which in particular hinders or even prevents the retrofittability of such closure systems. In the in the DE 103 23 696 A1 disclosed sliding door furniture, the closure system is mounted below the running shoe profiles.

Aufgabe der vorliegenden Erfindung ist es, ein Möbel mit einem Verschlusssystem bereit zu stellen, das eine einfachere Montage des Verschlusssystems ermöglicht.The object of the present invention is to provide a piece of furniture with a closure system which allows a simpler installation of the closure system.

Diese Aufgabe wird durch ein Möbel mit einem elektromechanischen Verschlusssystem mit den Merkmalen des Anspruchs 1 gelöst.This object is achieved by a piece of furniture with an electromechanical locking system having the features of claim 1.

Das erfindungsgemäße Möbel mit mindestens zwei zumindest einen Teilbereich einen Möbelkorpus schließenden auf parallelen Laufbahnen verfahrbaren Schiebetüren und einem elektromechanischen Verschlusssystem weist mindestens ein Verriegelungselement mit einem aus einer Freigabestellung einer Verriegelungsstellung verfahrbaren Riegel auf, mindestens eine Riegelaufnahme zur Aufnahme des Riegels in dessen Verriegelungsstellung, ein Gehäuse, in dem das Verriegelungselement zumindest teilweise und ein in den Riegel eingreifender Elektromotor aufgenommen ist. Der Elektromotor ist dabei über eine Steuereinheit ansteuerbar.The furniture according to the invention with at least two at least one part of a furniture body closing sliding on parallel tracks sliding doors and an electromechanical locking system has at least one locking element with a movable from a release position of a locking position latch, at least one latch receptacle for receiving the latch in its locking position, a housing in which the locking element is at least partially received and an engaging in the bolt electric motor. The electric motor can be controlled via a control unit.

Das Verriegelungselement liegt in einer parallel zur Verschieberichtung der Schiebetüren ausgerichteten Seitenwand einer ersten der Schiebetüren ein, wobei die Riegelaufnahme an einer der ersten der Schiebetüren zugewandten Seitenfläche einer zweiten der Schiebetüren angeordnet ist, wobei an dem Gehäuse ein Führungselement angeformt ist, dass in eine in dem Gehäuse zugewandten stehende Ausnehmung des Riegels zur Führung des Riegels in Schließrichtung ragt.The locking element is located in a parallel to the direction of sliding doors aligned side wall of a first of the sliding doors, wherein the bolt receptacle is disposed on one of the first sliding side facing the side surface of a second of the sliding doors, wherein on the housing a guide element is formed, that in one in the Housing facing standing recess of the bolt for guiding the bolt in the closing direction protrudes.

Ein derartiges elektromechanisches Verschlusssystem kann in einfacher Weise an einer der Schiebetüren des Schiebetürmöbels montiert werden.Such an electromechanical locking system can be easily mounted on one of the sliding doors of the sliding door furniture.

Als Riegelaufnahme für den Riegel kann dazu im einfachsten Falle eine den Querschnitt des Riegels entsprechend geformte Ausnehmung in der zweiten der Schiebetüren vorgesehen sein. Bauliche Veränderungen am Möbelkorpus wie beispielsweise das Ausfräsen von Aufnahmen zur Unterbringung des Verschlusssystems sind bei dem erfindungsgemäßen elektromechanischen Verschlusssystem nicht notwendig, da das Verschlusssystem gänzlich an den Schiebetüren angebracht ist. Dadurch ist ein Nachrüsten eines derartigen Verschlusssystems an einem vorhandenen Schiebetürmöbel in einfacher Weise ermöglicht.As a bolt receptacle for the bolt can be provided in the second case of the sliding doors in the simplest case a cross-section of the bolt correspondingly shaped recess. Structural changes to the furniture body, such as the milling of receptacles for accommodating the locking system are not necessary in the electromechanical locking system according to the invention, since the closure system is mounted entirely on the sliding doors. As a result, retrofitting of such a closure system on an existing sliding door furniture is made possible in a simple manner.

Vorteilhafte Ausführungsvarianten der Erfindung sind Gegenstand der Unteransprüche.Advantageous embodiments of the invention are the subject of the dependent claims.

Gemäß einer vorteilhaften Ausführungsvariante der Erfindung weist das Führungselement eine entsprechend dem Querschnitt der Ausnehmung mehreckigen, insbesondere viereckigen Querschnitt auf. Dadurch wird eine verdrehsichere translatorische Bewegung des Riegels in Schließrichtung bzw. entgegen der Schließrichtung ermöglicht.According to an advantageous embodiment of the invention, the guide element has a cross-section of the recess polygonal, in particular quadrangular cross-section. As a result, a rotationally secure translational movement of the bolt in the closing direction or opposite to the closing direction is made possible.

Gemäß einer weiteren vorteilhaften Ausführungsvariante der Erfindung ist das Verriegelungselement als Schneckengetriebe ausgebildet. Dadurch ist ein ausreichend großer Hub des Riegels bei gleichzeitig geringem Aufbau des Verriegelungselements ermöglicht.According to a further advantageous embodiment of the invention, the locking element is designed as a worm gear. As a result, a sufficiently large stroke of the bolt is made possible at the same time low construction of the locking element.

Gemäß einer weiteren vorteilhaften Ausführungsvariante der Erfindung weist die Steuereinheit zur Ansteuerung des Elektromotors einen aktiven Transponder, insbesondere einen RFID-, RD- oder Bluetooth-Transponder auf. Dieser ermöglicht eine Fernsteuerung des Verschlusssystems durch eine entsprechend ausgebildete Fernsteuerungseinheit, so dass das im geschlossenen Zustand von außerhalb des Möbels unzugängliche Verschlusssystem in einfacher Weise von außen ansteuerbar ist.According to a further advantageous embodiment variant of the invention, the control unit for controlling the electric motor has an active transponder, in particular an RFID, RD or Bluetooth transponder. This allows a remote control of the closure system by an appropriately trained remote control unit, so that in the closed state inaccessible from outside the furniture closure system can be controlled in a simple manner from the outside.

Dabei kann durch Einsatz einer speziellen Hardwareschnittstelle die Ansteuerung des Elektromotors und die Signalübertragung an die als Kommunikationsmodul dienende Steuereinheit voneinander getrennt werden.It can be separated from each other by using a special hardware interface, the control of the electric motor and the signal transmission to the serving as a communication module control unit.

Gemäß einer weiteren vorteilhaften Ausführungsvariante der Erfindung weist das Verschlusssystem einen mit der Steuereinheit gekoppelten ersten Positionserkennungssensor zur Erfassung einer aktuellen Position des Riegels relativ zum Gehäuse sowie einen zweiten Positionserkennungssensor zur Erfassung einer aktuellen Position der Schiebetüren zueinander oder auf der jeweiligen Laufbahn auf.According to a further advantageous embodiment of the invention, the closure system has a coupled to the control unit first position detection sensor for detecting a current position of the bolt relative to the housing and a second position detection sensor for detecting a current position of the sliding doors to each other or on the respective career.

Dadurch ist ermöglicht, einen Schließvorgang nur dann durch die Steuereinheit zuzulassen, wenn die Schiebetüren sich in der Schließposition befinden. Ein Ausfahren des Riegels in einer anderen Position der Schiebetüren als der Schließposition, bei der ein anschließendes Verschieben der Schiebetüren zu Beschädigungen der Schiebetüren und/oder des Riegels führen können, ist dadurch vermeidbar.This makes it possible to allow a closing operation only by the control unit when the sliding doors are in the closed position. An extension of the bolt in a different position of the sliding doors than the closed position, in which a subsequent displacement of the sliding doors can lead to damage to the sliding doors and / or the bolt, thereby avoidable.

Die Steuereinheit ist gemäß einer weiteren vorteilhaften Ausführungsvariante der Erfindung mit wenigstens einem Signalelement zur Ausgabe eines Schließzustandssignals gekoppelt.The control unit is coupled according to a further advantageous embodiment of the invention with at least one signal element for outputting a closed state signal.

Dieses Signalelement ist dabei bevorzugt als optisches oder akustisches Signalelement ausgebildet, so dass bei Betätigung eines Signalgebers zur Ausführung einer Schließbewegung des Verschlusssytems dem Benutzer durch das Signalelement angezeigt oder akustisch mitgeteilt wird, ob das Schiebetürenmöbel verschlossen ist oder nicht.This signal element is preferably designed as an optical or acoustic signal element, so that upon actuation of a signal generator for performing a closing movement of the closure system the user through the Signal element is displayed or communicated acoustically, whether the sliding door furniture is closed or not.

Gemäß einer nochmals weiteren Ausführungsvariante der Erfindung ist das Schließzustandssignal durch Kombination eines Signals des Positionserkennungssensors und einer von der Steuereinheit erfassten aktuellen Position des Riegels ermittelbar.According to yet another embodiment of the invention, the closed state signal can be determined by combining a signal of the position detection sensor and a detected by the control unit current position of the bolt.

Desweiteren ist nach einer vorteilhaften Ausführungsvariante der Erfindung in dem Gehäuse eine Energieversorgungseinheit für den Elektromotor und/oder die Steuereinheit aufgenommen, so dass bei Ausfall einer Hauptstromversorgung beispielsweise ein Schließen des Schiebetürenmöbels noch ermöglicht ist oder ein Signal angezeigt werden kann, das auf die fehlende Hauptstromversorgung hinweist oder dergleichen.Furthermore, according to an advantageous embodiment of the invention, a power supply unit for the electric motor and / or the control unit is accommodated in the housing, so that when a main power supply, for example, closing the sliding door furniture is still possible or a signal can be displayed, which indicates the lack of main power supply or similar.

In der nachfolgenden Figurenbeschreibung beziehen sich Begriffe wie oben, unten, links, rechts, vorne, hinten usw. ausschließlich auf die in den jeweiligen Figuren gewählte beispielhafte Darstellung und Position der Schiebetüren, des Verriegelungselementes, des Riegels, des Elektromotors und dergleichen. Diese Begriffe sind nicht einschränkend zu verstehen, das heißt, durch verschiedene Arbeitsstellungen oder die spiegelsymmetrische Auslegung oder dergleichen können sich diese Bezüge ändern.In the following description of the figures, terms such as above, below, left, right, front, back, etc. refer exclusively to the exemplary representation and position of the sliding doors, the locking element, the bolt, the electric motor and the like chosen in the respective figures. These Terms are not intended to be limiting, that is to say that these relationships may change as a result of different working positions or the mirror-symmetrical design or the like.

In den Figuren 1 und 2 sind mit den Bezugszeichen 1 und 2 zwei relativ zueinander auf parallel zueinander verlaufenden Laufbahnen verfahrbare Schiebetüren bezeichnet, mit denen ein Innenraum eines Möbels oder ein Teilbereich eines Innenraums eines Möbels geöffnet und verschlossen werden können.In the Figures 1 and 2 are designated by the reference numerals 1 and 2 two relative to each other on mutually parallel tracks movable sliding doors with which an interior of a piece of furniture or a portion of an interior of a piece of furniture can be opened and closed.

Wie in den Draufsichten der Figuren 1 und 2 zu erkennen ist, ist an einer ersten Schiebetür 1 ein Gehäuse 4 eines elektromechanischen Verschlusssystems 3 befestigt. Das Gehäuse 4 ist dabei bevorzugt an einer der zweiten Schiebetür 2 abgewandten Seitenfläche 12 der ersten Schiebetür 1 befestigt, die dem zu verschießenden Innenraum des Schiebetürmöbels zugewandt ist.As in the plan views of Figures 1 and 2 can be seen, a housing 4 of an electromechanical locking system 3 is attached to a first sliding door 1. The housing 4 is preferably attached to a side facing away from the second sliding door 2 side surface 12 of the first sliding door 1, which faces the interior of the sliding door furniture to be fired.

In dem zum elektromechanischen Verschlusssystem gehörenden Gehäuse 4 ist ein Verriegelungselement 5 aufgenommen, das in Figur 5 in einer Schnittansicht dargestellt ist. Das Verriegelungselement 5 weist dabei einen aus einer Freigabestellung in einer Verriegelungsstellung verfahrbaren Riegel 53 auf.In the belonging to the electromechanical locking system housing 4, a locking element 5 is accommodated, which in FIG. 5 is shown in a sectional view. The locking element 5 in this case has a movable from a release position in a locking position latch 53.

Dieser Riegel 53 ist durch ein bevorzugt als Schneckengetriebe ausgebildetes Verriegelungselement 5 in einer Richtung Z quer zur Verschieberichtung X der Schiebetüren 1, 2 verfahrbar. Der Riegel 53 ist dabei auf einem Teil seiner zylindrischen Mantelfläche mit einem Außengewinde 55 versehen, dass mit einem Innengewinde einer Hülse 52 kämmt. Die Hülse 52 ist auf einem stirnseitigen Randumfang mit einem Zahnkranz versehen, in den ein Zahnrad 71 eingreift, das über eine Antriebswelle eines Elektromotors 7 antreibbar ist und so den Riegel 53 von einer in Figur 1 und 3 dargestellten Offen-Stellung in eine in den Figuren 2 und 4 gezeigte Schließstellung zu bewegen vermag.This latch 53 can be moved transversely to the direction of displacement X of the sliding doors 1, 2 by a locking element 5, preferably designed as a worm gear, in a direction Z. The latch 53 is provided on a part of its cylindrical lateral surface with an external thread 55 that meshes with an internal thread of a sleeve 52. The sleeve 52 is provided on a front edge circumference with a sprocket into which a gear 71 engages, which is driven by a drive shaft of an electric motor 7 and so the bolt 53 of a in FIG. 1 and 3 shown open position in a in the Figures 2 and 4 shown closed position to move.

Um einen möglichst großen Hub des Riegels 53 bei gleichzeitig geringem Aufbauen des Verriegelungselements 5 in Richtung Z zu ermöglichen, ist an dem Gehäuse 4 ein Führungselement 45 angeformt, dass in eine dem Gehäuse 4 zugewandten stirnseitige Ausnehmung 54 des Riegels 53 zur Führung des Riegels 53 in Schließrichtung Z ragt.In order to allow the largest possible stroke of the bolt 53 with simultaneous low construction of the locking element 5 in the direction Z, a guide element 45 is formed on the housing 4, that in a housing 4 facing end-side recess 54 of the bolt 53 for guiding the bolt 53 in Closing direction Z protrudes.

Dieses Führungselement 45 ist dabei bevorzugt im Querschnitt mehreckig, insbesondere viereckig, besonders bevorzugt mit quadratischem Querschnitt ausgebildet und ermöglicht so eine drehfeste Lagerung des Riegels 53 an dem Führungselement 45, so dass bei Aktivierung des Elektromotors 7 lediglich die Hülse 52 in Drehbewegung versetzt wird und durch die Drehbewegung der Hülse 52 der Riegel 53 in oder entgegen der Schließrichtung Z, auf dem Führungselement 45 translatorisch bewegt wird.This guide element 45 is preferably polygonal in cross section, in particular quadrangular, particularly preferably designed with a square cross section and thus allows a rotationally fixed bearing of the bolt 53 on the guide member 45, so that upon activation of the electric motor 7, only the sleeve 52 is set in rotary motion and by the rotational movement of the sleeve 52 of the latch 53 in or against the closing direction Z, on the guide member 45th is moved translationally.

Wie in den Figuren 3 und 4 desweiteren gezeigt ist, weist das Gehäuse 4 ein an der Seitenwand 12 der Schiebetür 1 anliegendes Basisteil 43 auf, in dem eine Ausnehmung 44 vorgesehen ist, durch die die Hülse 52 bei der Montage des Verriegelungselements 5 durchgesteckt wird, so dass lediglich der Zahnkranz 51 im Innenraum des Gehäuses 4 verbleibt.As in the FIGS. 3 and 4 is further shown, the housing 4 has a voltage applied to the side wall 12 of the sliding door 1 base 43, in which a recess 44 is provided through which the sleeve 52 is inserted in the assembly of the locking element 5, so that only the sprocket 51 in Interior of the housing 4 remains.

Das Gehäuse 4 weist desweiteren einen auf das Basisteil aufsetzbaren Gehäusedeckel 41 und einen eine Öffnung im Gehäusedeckel 41 verschließenden zweiten Gehäusedeckel 42 auf. Der zweite Gehäusedeckel 42 dient dabei dem einfachen Zugang des Gehäuseinneren zum Austausch von den der Stromversorgung dienenden Akkumulatoren 6.The housing 4 furthermore has a housing cover 41 which can be placed on the base part and a second housing cover 42 which closes an opening in the housing cover 41. The second housing cover 42 serves for the easy access of the housing interior for the exchange of the batteries 6 serving for the power supply.

Wie in den Figuren 1 und 2 desweiteren erkennbar ist, ragt die Hülse 52 des Verriegelungselementes in eine entsprechend geformte Bohrung der ersten Schiebetür 1, so dass in der Offen-Stellung des Verriegelungselements 5 die Hülse 52 vorzugsweise bündig mit der der zweiten Schiebetür 2 zugewandten Seitenfläche 11 der ersten Schiebetür 1 endet. Das der zweiten Schiebetür 2 zugewandte Ende des Riegels 53 ist in der Offen-Stellung des Verriegelungselementes 5 vorzugsweise ebenfalls bündig mit der Seitenfläche 11 der ersten Schiebetür 1.As in the Figures 1 and 2 Furthermore, the sleeve 52 of the locking element protrudes into a correspondingly shaped bore of the first sliding door 1, so that in the open position of the locking element 5, the sleeve 52 preferably ends flush with the second sliding door 2 facing side surface 11 of the first sliding door 1. The second sliding door 2 facing the end of the bolt 53 is preferably also flush with the side surface 11 of the first sliding door 1 in the open position of the locking element 5.

In der Schließstellung (Figur 2) ist der Riegel 53 so weit aus der Hülse 52 in Richtung der zweiten Schiebetür 2 translatorisch verschoben, dass der Riegel in eine entsprechende Riegelaufnahme in der der ersten Schiebetür 1 zugwandten Seitenfläche 21 der zweiten Schiebetür 2 ragt, so dass die beiden Schiebetüren 1, 2 durch den Riegel 53 formschlüssig gegen ein Verschieben der Schiebetüren 1, 2 in Verschieberichtung X als auch gegen eine vertikale Verschiebung der Schiebetüren 1, 2 (Aushebeln) formschlüssig gesichert sind.In the closed position ( FIG. 2 ), the bolt 53 so far from the sleeve 52 in the direction of the second sliding door 2 translationally displaced, that the bolt in a corresponding latch receptacle in the first sliding door 1 zugwandten side surface 21 of the second sliding door 2 projects, so that the two sliding doors 1, 2 positively locked by the bolt 53 against displacement of the sliding doors 1, 2 in the direction of displacement X as well as against a vertical displacement of the sliding doors 1, 2 (levering).

Zur Ansteuerung des Elektromotors 7 ist in dem Gehäuse 4 bevorzugt eine Steuereinheit 10 aufgenommen, die einen aktiven Transponder, insbesondere einen RFID-, RD- oder Bluetooth-Transponder aufweist. Dabei ist über eine spezielle Hardwareschnittstelle eine Ansteuerung des Elektromotors von einer Datenübertragung an die Steuereinheit 10 getrennt ausführbar.To control the electric motor 7, a control unit 10 is preferably received in the housing 4, which has an active transponder, in particular an RFID, RD or Bluetooth transponder. It is about a special hardware interface a control of the electric motor of a data transmission to the control unit 10 separately executable.

Die Steuereinheit 10 ist bevorzugt mit einem ersten Positionserkennungssensor 8 zur Erfassung einer aktuellen Position des Riegels 53 relativ zu dem Gehäuse 4 gekoppelt. Wie in Figur 5 gezeigt, ist der erste Positionserkennungssensor 8 derart in dem Gehäuse 4 positioniert, dass die Stellung des Riegels 53 relativ zur Hülse 52 detektierbar ist. Der erste Positionserkennungssensor 8 ist dabei bevorzugt als optischer Sensor ausgebildet. Die Detektionsrichtung 81 erfolgt dabei vorzugsweise senkrecht zur Bewegungsrichtung Z des Riegels 53.The control unit 10 is preferably coupled to a first position detection sensor 8 for detecting a current position of the bolt 53 relative to the housing 4. As in FIG. 5 1, the first position detection sensor 8 is positioned in the housing 4 such that the position of the latch 53 relative to the sleeve 52 is detectable. The first position detection sensor 8 is preferably designed as an optical sensor. The detection direction 81 is preferably perpendicular to the direction of movement Z of the bolt 53.

Desweiteren ist die Steuereinheit 10 mit einem zweiten Positionserkennungssensor 9 zur Erfassung einer aktuellen Position der Schiebetüren 1, 2 zueinander oder auf der Position der jeweiligen Schiebetüren 1, 2 auf der jeweiligen Laufbahn gekoppelt. Die Detektionsrichtung 91 erfolgt dabei vorzugsweise senkrecht zu den Seitenfläche 12, 22 der Schiebetüren 1, 2.Furthermore, the control unit 10 is coupled to a second position detection sensor 9 for detecting a current position of the sliding doors 1, 2 to each other or to the position of the respective sliding doors 1, 2 on the respective track. The detection direction 91 is preferably perpendicular to the side surface 12, 22 of the sliding doors 1, 2.

Die Steuereinheit ist desweiteren so ausgebildet, dass die aktuelle Position des Riegels 53 erfassbar ist, so dass beispielsweise durch Kombination der Informationen über die Position des Riegels 53 und der Schiebetüren die Ansteuerung eines Informationssignales betreffend den Schließzustand des Möbels ausgebbar ist.The control unit is further designed so that the current position of the bolt 53 can be detected, so that, for example, by combining the information about the position of the bolt 53 and the sliding doors, the control of an information signal regarding the closed state of the furniture can be output.

Dazu sind vorzugsweise optische und/oder akustische Signalelemente als Teil des Verschlusssystems vorgesehen, die über die Steuereinheit ansteuerbar sind und mit denen beispielsweise die Schließstellung des Riegels 53 und damit die Verriegelung der Schiebetüren 1, 2 durch den Riegel 53 beispielsweise über ein Lichtsignal anzeigbar ist.For this purpose, optical and / or acoustic signal elements are preferably provided as part of the closure system, which are controlled via the control unit and with which, for example, the closed position of the bolt 53 and thus the locking of the sliding doors 1, 2 can be displayed by the latch 53, for example via a light signal.

Wie in Figur 6 gezeigt ist, ist mit Hilfe der Positionserkennungssensoren 8, 9 eine Anzeige eines aktuellen Schließ- oder Öffnungszustandes des Schiebetürmöbels ermöglicht.As shown in FIG. 6, an indication of a current closing or opening state of the sliding-door furniture is made possible with the aid of the position-detection sensors 8, 9.

So kann zum einen in regelmäßigen Abständen oder bei Auslösung eines Schließbefehls durch eine mit dem Transponder der Steuereinheit 10 drahtlos gekoppelte Bedieneinheit mithilfe der Steuereinheit und den mit dieser gekoppelten Positionserkennungssensoren 8, 9 überprüft werden, ob die Schiebetüren 1,2 in ihrer Schließstellung positioniert sind oder nicht.Thus, on the one hand, it can be checked at regular intervals or when a closing command is triggered by a control unit wirelessly coupled to the transponder of the control unit 10 by means of the control unit and the position detection sensors 8, 9 coupled thereto, whether the sliding doors 1, 2 are positioned in their closed position or Not.

Sofern die Schiebetüren 1,2 in ihrer Schließstellung positioniert sind, wird abgefragt, ob der Riegel 53 in seiner Schließstellung positioniert ist oder nicht.If the sliding doors are positioned 1,2 in its closed position, it is queried whether the latch 53 is positioned in its closed position or not.

Sofern der Riegel 53 in seiner Schließstellung positioniert ist, erfolgt die Ausgabe eines Signals an die Bedieneinheit mit einer Information, ob die Schiebetüren 1, 2 durch den Riegel 53 verschlossen sind oder nicht.If the latch 53 is positioned in its closed position, the output of a signal to the control unit with an information as to whether the sliding doors 1, 2 are closed by the latch 53 or not.
