Description

Die vorliegende Erfindung betrifft ein Möbel mit mindestens einer zumindest einen Teilbereich eines Möbelkorpus schließenden auf einer Laufbahn verfahrbaren Schiebetür und einem elektromechanischen Verschlusssystem gemäß dem Oberbegriff des Anspruchs 1.The present invention relates to a piece of furniture with at least one sliding body that closes at least a portion of a furniture body and can be moved on a running track and an electromechanical locking system according to the preamble of claim 1.

Ein gattungsgemäßes Verschlusssystem für ein Möbel mit einer oder mehreren Schiebetüren ist beispielsweise aus der DE 103 23 696 A1 bekannt. Das dort gezeigte Schiebetürmöbel weist zwei Schiebetüren auf, die in parallelen Verschiebeebenen in Laufschuhprofilen aufgenommen und geführt sind. In diesen Laufschuhprofilen sind Griffstücke vorgesehen, die sich in einer Schließposition der Schiebetüren senkrecht zur Verschieberichtung betrachtet überdecken.A generic locking system for a piece of furniture with one or more sliding doors is for example from the DE 103 23 696 A1 known. The sliding door furniture shown there has two sliding doors, which are accommodated and guided in running shoe profiles on parallel sliding levels. Grip pieces are provided in these running shoe profiles, which overlap when viewed 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 prevent these sliding doors from being lifted out, the mutually facing sides of the handle pieces are designed in the manner of a tongue and groove connection, so that levering one of the sliding doors in the region of the handle point is prevented by the engagement of the two handle pieces with one another.

Bei dieser Bauweise zur Verhinderung eines Aushebens der Schiebetüren müssen die Türen bei diesem Verschlusssystem mit unterschiedlichen Bauteilen ausgestattet werden, um das funktionsgemäße Zusammenwirken der Griffstücke gewährleisten zu können.With this design to prevent the sliding doors from being lifted, the doors in this locking system must be equipped with different components in order to ensure the functional interaction of the handle pieces.

Aufgabe der vorliegenden Erfindung ist es, ein Möbel derart weiterzubilden, dass neben der Aushebesicherung auch ein Wegdrücken der Schiebetür von einer parallel zu dieser angeordneten Wand oder einer zweiten Schiebetür senkrecht zur Verschieberichtung der Schiebetür verhindert wird.It is an object of the present invention to develop a piece of furniture in such a way that, in addition to securing it against being lifted out, pushing the sliding door away from a wall arranged parallel to it or a second sliding door perpendicular to the direction of displacement of the sliding door is prevented.

Diese Aufgabe wird durch ein Möbel mit den Merkmalen des Anspruchs 1 gelöst.This object is achieved by a piece of furniture with the features of claim 1.

Das erfindungsgemäße Möbel mit mindestens einer zumindest einen Teilbereich eines Möbelkorpus schließenden auf einer Laufbahn verfahrbaren Schiebetür und einem elektromechanischen Verschlusssystem, mit dem die Schiebetür in einer Schließposition verriegelbar ist, wobei das elektromechanische Verschlusssystem einen zwischen einer Freigabestellung und einer Verriegelungsstellung mittels eines Elektromotors in und entgegen einer Schließrichtung verfahrbaren Schließbolzen aufweist. In einem Hohlraum des Schließbolzens ist ein Sperrelement aufgenommen, das zwischen einer aus einer Öffnung in einer Mantelfläche des Schließbolzens vorstehenden Sperrstellung und einer aus dieser nicht vorstehenden Neutralstellung verschiebbar ist.The furniture according to the invention with at least one partial area of a furniture body closing sliding door movable on a track and an electromechanical locking system with which the sliding door can be locked in a closed position, the electromechanical locking system has a locking bolt which can be moved in and against a closing direction between an unlocked position and a locking position by means of an electric motor. A locking element is received in a cavity of the locking bolt and can be displaced between a locking position protruding from an opening in a lateral surface of the locking bolt and a neutral position not protruding from this.

Ein den Elektromotor aufnehmendes Gehäuse des Verschlusssystems ist an einer der Schiebetür abgewandten Seite eines parallel zur Schiebetür angeordneten Wandelements des Möbels befestigt, wobei das Gehäuse eine in eine Bohrung des Wandelements vorstehende Führung aufweist, in der der Schließbolzen verschiebbar geführt ist, wobei der Schließbolzen in der Verriegelungsstellung in eine an der dem Wandelement zugewandten Seite vorgesehene Tasche der Schiebetür vorsteht.A housing of the locking system receiving the electric motor is fastened on a side of the wall element of the furniture which is arranged parallel to the sliding door and which faces away from the sliding door, the housing having a guide protruding into a bore in the wall element, in which the locking bolt is slidably guided, the locking bolt in the Locking position protrudes into a pocket of the sliding door provided on the side facing the wall element.

Mit einem solchen elektromechanischen Verschlusssystem wird durch den Schließbolzen selbst eine Verriegelung der Schiebetür dadurch bewirkt, dass der Schließbolzen in der Verriegelungsstellung in eine dafür vorgesehene Bolzenaufnahme oder Ausnehmung der Schiebetür vorsteht und dadurch ein Verschieben der Schiebetür in Öffnungsrichtung blockiert.With such an electromechanical locking system, the locking bolt itself locks the sliding door in that the locking bolt protrudes into a bolt receptacle or recess in the sliding door in the locking position and thereby blocks sliding of the sliding door in the opening direction.

Durch das aus der Mantelfläche des Schließbolzens vorstehende Sperrelement wird zusätzlich eine Bewegung der Schiebetür aus dem Eingriff des Schließbolzens verhindert, welches innerhalb der Bolzenaufnahme aus der Mantelfläche des Schließbolzens vorsteht und so ein Zurückziehen des Schließbolzens aus der Bolzenaufnahme bzw. ein Wegdrücken der Schiebetür aus dem Eingriff des Schließbolzens verhindert.The locking element protruding from the outer surface of the locking bolt additionally prevents movement of the sliding door from the engagement of the locking bolt, which protrudes from the outer surface of the locking bolt within the bolt receptacle, and thus retraction of the locking bolt from the bolt receptacle or pushing the sliding door out of engagement of the locking bolt prevented.

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 ist in dem Hohlraum des Schließbolzens ein winklig, insbesondere rechtwinklig zum Sperrelement verfahrbarer, von dem Elektromotor antreibbarer Antriebsbolzen aufgenommen. Dabei ist besonders bevorzugt ein in den Hohlraum des Schließbolzens vorstehendes stirnseitiges Ende eines Bolzenhalses des Antriebsbolzens als Rampe geformt, die an einer Schrägführung des Sperrelements anliegt. Dadurch kann in einfacher Weise das Sperrelement durch Verschieben des Antriebsbolzens in Schließrichtung aus der Mantelfläche des Schließbolzens herausgeschoben werden.According to an advantageous embodiment variant of the invention, a drive bolt which can be driven by the electric motor and which can be driven at an angle, in particular at right angles to the locking element, is accommodated in the cavity of the locking bolt. In this case, a front end of a bolt neck of the drive bolt which projects into the cavity of the locking bolt is particularly preferably shaped as a ramp which bears against an oblique guide of the locking element. As a result, the locking element can be moved in a simple manner by moving the drive bolt be pushed out of the outer surface of the locking bolt in the closing direction.

Gemäß einer weiteren vorteilhaften Ausführungsvariante ist der Antriebsbolzen über ein Federelement mit dem Schließbolzen gekoppelt. Dieses Federelement ist bevorzugt als eine den Bolzenhals des Antriebsbolzens umgreifende Druckfeder ausgebildet, die zwischen einem Kragen des Antriebsbolzens und einer Stufenausnehmung des Schließbolzens einliegt.According to a further advantageous embodiment variant, the drive bolt is coupled to the locking bolt via a spring element. This spring element is preferably designed as a compression spring encompassing the bolt neck of the drive bolt, which lies between a collar of the drive bolt and a step recess in the locking bolt.

Die Federkonstante dieses Federelements ist dabei so bemessen, dass bei einem Vorschieben des Antriebsbolzens durch den Elektromotor in Schließrichtung zunächst der Schließbolzen in die Verriegelungsstellung gegen einen Anschlag gedrückt wird und nach Erreichen des Anschlages unter Stauchung des Federelements der Antriebsbolzen weiter in den Hohlraum des Schließbolzens eingeschoben wird und dabei das Sperrelement von der Neutralstellung in die aus der Öffnung in der Mantelfläche des Schließbolzens vorstehende Sperrstellung verschoben wird.The spring constant of this spring element is dimensioned such that when the drive bolt is pushed forward by the electric motor in the closing direction, the locking bolt is first pressed into the locking position against a stop, and after reaching the stop, the drive bolt is pushed further into the cavity of the locking bolt while compressing the spring element and the locking element is shifted from the neutral position into the locking position protruding from the opening in the lateral surface of the locking bolt.

Mit einer Kopplung des Antriebsbolzens mit dem Schließbolzen über ein solches Federelement ist es ermöglicht, dass bei einem Verriegelungsvorgang der Schiebetür der Antriebsbolzen zunächst den Schließbolzen aus der Freigabestellung in die Verriegelungsstellung, in der ein Verschieben bzw. Öffnen der Schiebetür blockiert ist, vorschiebt und anschließend durch Weiterdrücken des Antriebsbolzens gegen den Schließbolzen gegen die Federkraft des Federelements das Sperrelement aus der Mantelfläche des Schließbolzens heraus bewegt.Coupling the drive pin with the locking pin via such a spring element makes it possible for the drive pin to first push the locking pin out of the release position into the locking position in which a sliding or opening of the sliding door is blocked, and then when the sliding door is locked Further pushing the drive bolt against the locking bolt against the spring force of the spring element moves the locking element out of the outer surface of the locking bolt.

Gemäß einer weiteren bevorzugten Ausführungsvariante der Erfindung ist in der Mantelfläche des Schließbolzens ein in Schließrichtung sich erstreckendes Langloch vorgesehen, in der ein aus einer Mantelfläche des Antriebsbolzens vorstehender Sicherungsstift aufgenommen ist.According to a further preferred embodiment variant of the invention, an elongated hole extending in the closing direction is provided in the outer surface of the locking bolt, in which a locking pin protruding from an outer surface of the drive bolt is received.

Der Sicherungsstift ermöglicht in einfacher Weise ein Zurückholen des Schließbolzens aus der Verriegelungsstellung in die Freigabestellung, wenn der Antriebsbolzen durch den Elektromotor entgegen der Schließrichtung bewegt wird, wobei der Sicherungsstift den Antriebsbolzen mit dem Schließbolzen koppelt.The locking pin enables the locking bolt to be brought back from the locking position into the release position in a simple manner when the drive bolt is moved against the closing direction by the electric motor, the locking pin coupling the drive bolt to the locking bolt.

Durch das Langloch in der Mantelfläche des Schließbolzens wird die für die Bewegung des Sperrelements benötigte Axialverschiebung des Antriebsbolzens relativ zum Schließbolzen ermöglicht.The elongated hole in the outer surface of the locking bolt enables the axial displacement of the drive bolt required for the movement of the locking element relative to the locking bolt.

Die Übertragung der von dem Elektromotor bereitgestellten Antriebskraft erfolgt gemäß einer weiteren bevorzugten Ausführungsvariante über eine Welle, die mit einem Exzenter, insbesondere einer Exzenterscheibe, verbunden ist, wobei ein an dem Exzenter angeordneter Exzenterpin alternierend zwischen einer Freigabestellung und einer Verriegelungsstellung bewegbar ist und bei einer Bewegung von der Freigabestellung in die Verriegelungsstellung den Antriebsbolzen in Schließrichtung drückt.According to a further preferred embodiment variant, the drive force provided by the electric motor is transmitted via a shaft which is connected to an eccentric, in particular an eccentric disk, an eccentric pin arranged on the eccentric being movable alternately between a release position and a locking position and during a movement from the release position to the locking position presses the drive bolt in the closing direction.

Gemäß einer weiteren Ausführungsvariante ist das Wandelement des Möbels, an dem das Gehäuse befestigt ist, als auf einer parallel zur Schiebetür auf einer Laufbahn geführte zweite Schiebetür ausgebildet. Das Gehäuse ist dabei bevorzugt an der inneren der beiden Schiebetüren befestigt, wobei der Schließbolzen bei einem Verriegelungsvorgang in die Bolzenaufnahme der äußeren Schiebetür vorgeschoben wird.According to a further embodiment variant, the wall element of the piece of furniture, to which the housing is fastened, is designed as a second sliding door that is guided on a track parallel to the sliding door. The housing is preferably attached to the inner of the two sliding doors, the locking bolt being pushed into the bolt receptacle of the outer sliding door during a locking process.

Gemäß einer weiteren vorteilhaften Ausführungsvariante ist das Gehäuse zumindest zweiteilig ausgebildet, wobei in einem ersten Gehäuseteil zumindest der Elektromotor aufgenommen und die in die Bohrung des Wandelements vorstehende Führung an einem zweiten Gehäuseteil angeformt ist.According to a further advantageous embodiment variant, the housing is formed at least in two parts, at least the electric motor being accommodated in a first housing part and the guide projecting into the bore of the wall element being integrally formed on a second housing part.

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 des Verschlusssystems, des Schließbolzens, des Sperrelements, des Antriebsbolzens, des Federelements und dergleichen. Diese Begriffe sind nicht einschränkend zu verstehen, d.h., durch verschiedene Arbeitsstellungen oder die spiegelsymmetrische Auslegung oder dergleichen können sich diese Bezüge ändern.In the following description of the figures, terms such as top, bottom, left, right, front, rear etc. relate exclusively to the exemplary representation and position of the locking system, the locking bolt, the locking element, the drive bolt, the spring element and the like selected in the respective figures. These terms are not to be understood as restrictive, i.e. these references can change due to different working positions or the mirror-symmetrical design or the like.

In den Figuren 1 und 2 sind mit dem 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 kann.In the Figures 1 and 2 are designated with the reference numerals 1 and 2 two sliding doors that can be moved relative to one another on parallel running tracks, with which an interior of a piece of furniture or a partial area of an interior of a piece of furniture can be opened and closed.

Denkbar ist auch die mit dem Bezugszeichen 1 versehene Schiebetür als fest stehendes Wandelement auszuführen.It is also conceivable to design the sliding door provided with reference number 1 as a fixed wall element.

Wie in der Draufsicht der Figur 1 zu erkennen ist, ist an der Schiebetür 1 ein Gehäuse mit einem ersten Gehäuseteil 3 und einem zweiten Gehäuseteil 4 eines Verschlusssystems befestigt.As in the top view of the Figure 1 It can be seen that a housing with a first housing part 3 and a second housing part 4 of a locking system is fastened to the sliding door 1.

Das Gehäuse mit den beiden Gehäuseteilen 3 und 4 ist dabei bevorzugt an der am Möbel weiter innen liegenden Schiebetür 1 auf einer der Schiebetür 2 abgewandten Seite der Schiebetür 1 befestigt, so dass ein Zugriff auf das Verschlusssystem bei geschlossener Schiebetür 2 bzw. bei geschlossenen Schiebetüren 1, 2 nicht möglich ist.The housing with the two housing parts 3 and 4 is preferably attached to the sliding door 1 located further inside the furniture on a side of the sliding door 1 facing away from the sliding door 2, so that access to the locking system when the sliding door 2 is closed or when the sliding doors 1 are closed , 2 is not possible.

Die Figuren 1 und 2 zeigen das Verschlusssystem in einer Verriegelungsstellung, bei der ein Schließbolzen 7 aus der Schiebetür 1 senkrecht zu einer Verschieberichtung y der Schiebetüren 1, 2 in eine Bolzenaufnahme 30 in der Schiebetür 2 vorsteht.The Figures 1 and 2 show the locking system in a locking position, in which a locking pin 7 from the sliding door 1 perpendicular to a direction of displacement y of the sliding doors 1, 2 protrudes into a bolt receptacle 30 in the sliding door 2.

Wie in den Figuren 2 und 3 gezeigt, weist das elektromechanische Verschlusssystem den zwischen einer Freigabestellung, dargestellt in Figur 4, und einer Verriegelungsstellung, dargestellt in den Figuren 1, 2 und 5 verfahrbaren Schließbolzen 7 auf, der in und entgegen einer Schließrichtung x verfahrbar ist.As in the Figures 2 and 3rd shown, the electromechanical locking system has the between a release position, shown in FIG Figure 4 , and a locking position, shown in the Figures 1, 2 and 5 movable locking bolt 7, which is movable in and against a closing direction x.

In einem Hohlraum des Schließbolzens 7 ist ein Sperrelement 10 aufgenommen, das zwischen einer aus einer Öffnung 16 in einer Mantelfläche 23 des Schließbolzens 7 vorstehenden Sperrstellung und einer aus dieser nicht vorstehenden Neutralstellung, gezeigt in den Figuren 4 und 5, verschiebbar ist.In a cavity of the locking bolt 7, a locking element 10 is received, which between a locking position protruding from an opening 16 in a lateral surface 23 of the locking bolt 7 and a neutral position not protruding therefrom, shown in FIGS Figures 4 and 5 , is movable.

Die Bolzenaufnahme 30 in der Schiebetür 2 ist dabei im Inneren der Schiebetür 2 breiter ausgeführt als die Eintrittsöffnung der Bolzenaufnahme 30, die geringfügig, insbesondere um weniger als 2mm größer bemessen ist als der Durchmesser des Schließbolzens 7, um das Herausfahren des Sperrelements 10 aus der Mantelfläche 23 des Schließbolzens 7 nach dem Passieren der Eintrittsöffnung der Bolzenaufnahme 30 zu ermöglichen.The bolt receptacle 30 in the sliding door 2 is made wider inside the sliding door 2 than the entry opening of the bolt receptacle 30, which is dimensioned slightly, in particular less than 2 mm, larger than the diameter of the locking bolt 7 in order to move the locking element 10 out of the outer surface 23 of the locking bolt 7 after passing through the entry opening of the bolt receptacle 30.

Das Sperrelement 10 steht dabei in seiner Sperrstellung bevorzugt um 2 bis 8 mm gegenüber der Mantelfläche 23 des Schließbolzens 7 hervor.The locking element 10 protrudes in its locking position preferably by 2 to 8 mm with respect to the lateral surface 23 of the locking bolt 7.

Die Eintrittsöffnung der Bolzenaufnahme 30 ist dabei so bemessen, dass deren Durchmesser kleiner ist als der Durchmesser des Schließbolzens 7 plus das Abmaß des aus der Mantelfläche 23 des Schließbolzens 7 vorstehenden Sperrelements 10.The entry opening of the bolt receptacle 30 is dimensioned such that its diameter is smaller than the diameter of the locking bolt 7 plus the dimension of the locking element 10 protruding from the outer surface 23 of the locking bolt 7.

Zur Betätigung des Sperrelements 10 ist in der hier gezeigten Ausführungsvariante ein Antriebsbolzen 8 vorgesehen. Der Antriebsbolzen 8 weist einen Kragen 26 auf sowie einen sich von diesem erstreckenden Bolzenhals 25, der in einer vorzugsweise zentralen, sich in Schließrichtung x erstreckenden Längsbohrung des Schließbolzens 7 verfahrbar aufgenommen ist.In the embodiment variant shown here, a drive pin 8 is provided for actuating the locking element 10. The drive bolt 8 has a collar 26 and a bolt neck 25 extending therefrom, which is movably received in a preferably central longitudinal bore of the locking bolt 7 extending in the closing direction x.

Der Antriebsbolzen 8 steht dabei mit dem Elektromotor 9 über einen Exzenter 5 in Wirkverbindung. Dabei ist der Elektromotor 9 über eine Welle 11 mit dem Exzenter 5 verbunden. An dem Exzenter 5 ist ein Exzenterpin 14 angeordnet, der sich im Betrieb des Elektromotors 9 alternierend zwischen einer Freigabestellung und einer Verriegelungsstellung bewegt und bei einer Bewegung von der Freigabestellung in die Verriegelungsstellung den Antriebsbolzen 8 in Schließrichtung x drückt.The drive pin 8 is in operative connection with the electric motor 9 via an eccentric 5. The electric motor 9 is connected to the eccentric 5 via a shaft 11. On the eccentric 5, an eccentric pin 14 is arranged, which is in operation of the electric motor 9 alternately moved between a release position and a locking position and pushes the drive bolt 8 in the closing direction x when moving from the release position into the locking position.

Wie in Figur 3 gezeigt ist, ist an dem Kragen 26 des Antriebsbolzens 8 ein sich in Schließrichtung x erstreckender Führungsschlitz 18 an einer Seitenkante des Kragens 26 vorgesehen, in dem ein schienenartiger Steg des ersten Gehäuseteils 3 einliegt und so ein Verdrehen des Antriebsbolzens 8 um eine sich in Schließrichtung x erstreckende Drehachse verhindert.As in Figure 3 is shown, on the collar 26 of the drive pin 8 a guide slot 18 extending in the closing direction x is provided on a side edge of the collar 26, in which a rail-like web of the first housing part 3 lies and thus a rotation of the drive pin 8 by a in the closing direction x extending axis of rotation prevented.

Das von dem Kragen 26 entfernte Ende des Bolzenhalses 25 des Antriebsbolzens 8 ist hier als Rampe 19 geformt, die an einer Schrägführung 20 des Sperrelement 10 anliegt, um die Schließbewegung des Antriebsbolzens 8 in Schließrichtung x in eine Sperrbewegung in einer Sperr-Richtung z des Sperrelements 10 umzuwandeln. Denkbar sind hier auch andere mechanische Ausgestaltungen, mit denen eine solche Bewegungsrichtungsumwandlung erreicht werden kann.The end of the bolt neck 25 of the drive bolt 8 which is distant from the collar 26 is here shaped as a ramp 19 which bears against an inclined guide 20 of the locking element 10 for the closing movement of the drive bolt 8 in the closing direction x into a locking movement in a locking direction z of the locking element 10 convert. Other mechanical configurations are also conceivable with which such a conversion of the direction of movement can be achieved.

Zur exakten Führung des Sperrelements 10 ist die Öffnung 16 in der Mantelfläche 23 des Schließbolzens 7 dem Querschnitt eines Sperrkopfes 21, der in der Sperrstellung aus der Mantelfläche 23 des Schließbolzens 7 vorsteht, entsprechend angepasst.For the exact guidance of the locking element 10, the opening 16 in the outer surface 23 of the locking bolt 7 is correspondingly adapted to the cross section of a locking head 21, which projects from the outer surface 23 of the locking bolt 7 in the locked position.

Wie in den Figuren 2-5 des Weiteren gezeigt ist, ist der Antriebsbolzen 8 über ein Federelement 6 mit dem Schließbolzen 7 gekoppelt. Das Federelement 6 ist hier als spiralförmige Druckfeder ausgebildet, die den Bolzenhals 25 des Antriebsbolzens 8 umgreift und zwischen dem Kragen 26 des Antriebsbolzens 8 und einer Stufenausnehmung 28 in einem dem Kragen 26 des Antriebsbolzens 8 zugewandten Ende des Schließbolzens (7) einliegt.As in the Figures 2-5 Furthermore, the drive pin 8 is coupled to the locking pin 7 via a spring element 6. The spring element 6 is designed here as a helical compression spring which engages around the pin neck 25 of the drive pin 8 and lies between the collar 26 of the drive pin 8 and a step recess 28 in an end of the locking pin (7) facing the collar 26 of the drive pin 8.

Des Weiteren ist in der Mantelfläche 23 des Schließbolzens 7 ein in Schließrichtung x sich erstreckendes Langloch 15 vorgesehen, in dem ein aus einer Mantelfläche des Antriebsbolzens 8 vorstehender Sicherungsstift 22 aufgenommen ist, der der Kopplung des Antriebsbolzens 8 mit dem Schließbolzen 7 dient und eine Relativverschiebung zwischen dem Antriebsbolzen 8 und dem Schließbolzen 7 um die Länge des Langlochs 15 ermöglicht.Furthermore, an elongated hole 15 extending in the closing direction x is provided in the lateral surface 23 of the locking bolt 7, in which a locking pin 22 protruding from a lateral surface of the drive bolt 8 is received, which serves to couple the drive bolt 8 to the locking bolt 7 and a relative displacement between allows the drive pin 8 and the locking pin 7 by the length of the elongated hole 15.

Die Länge des Langlochs 15 ist dabei so bemessen, dass die mögliche Verschiebung des Antriebsbolzens 8 relativ zum Schließbolzen 7 der für das Ausfahren des Sperrelements 10 aus der Öffnung 16 in der Mantelfläche 23 des Schließbolzens 7 entspricht.The length of the elongated hole 15 is dimensioned such that the possible displacement of the drive bolt 8 relative to the locking bolt 7 corresponds to that for the extension of the locking element 10 out of the opening 16 in the lateral surface 23 of the locking bolt 7.

Um eine Verriegelung der Schiebetür 2 mit der Schiebetür 1 durchzuführen, wird der Antriebsbolzen 8, durch den Elektromotor 9 wie zuvor beschrieben angetrieben, aus der in Figur 4 gezeigten Position des Antriebsbolzens 8 und des Schließbolzens 7, der in der Freigabestellung in die Schiebetür 1 eingefahren ist, in die in Figur 5 gezeigte Verriegelungsstellung, bei der der Schließbolzen 7 in die Bolzenaufnahme 30 der Schiebetür 2 vorgeschoben ist, in Schließrichtung x verfahren. Dabei drückt der Antriebsbolzen 8 gegen das Federelement 6.In order to interlock the sliding door 2 with the sliding door 1, the drive bolt 8 is driven by the electric motor 9 as described above, from which in FIG Figure 4 shown position of the drive pin 8 and the locking pin 7, which is retracted in the release position in the sliding door 1, in the in Figure 5 shown locking position, in which the locking bolt 7 is pushed into the bolt receptacle 30 of the sliding door 2, move in the closing direction x. The drive pin 8 presses against the spring element 6.

Die Andruckkraft wird von dem Federelement 6 auf den Schließbolzen 7 übertragen und drückt den Schließbolzen 7 dabei in die in Figur 5 gezeigte Verriegelungsstellung.The pressing force is transmitted from the spring element 6 to the locking bolt 7 and presses the locking bolt 7 into the in Figure 5 locking position shown.

Das Federelement 6 wird dabei nur geringfügig gestaucht. Die Federkonstante des Federelements 6 ist hier so bemessen, dass bei einem Vorschieben des Antriebsbolzens 8 durch den Elektromotor 9 in Schließrichtung x aufgrund der relativ zur Federkonstante des Federelements 6 geringen Gleitreibung des Schließbolzens 7 in einer Führung 27 eines zweiten Gehäuseteils 4 der Schließbolzen 7 zunächst in die Verriegelungsstellung gegen einen Anschlag 29 gedrückt wird.The spring element 6 is compressed only slightly. The spring constant of the spring element 6 is dimensioned here such that when the drive bolt 8 is pushed forward by the electric motor 9 in the closing direction x, due to the low sliding friction of the locking bolt 7 relative to the spring constant of the spring element 6, in a guide 27 of a second housing part 4 of the locking bolt 7 initially in the locking position is pressed against a stop 29.

Der Schließbolzen 7 weist dabei bevorzugt an seinem dem Kragen 26 zugewandten Ende seinerseits einen Kragen 24 auf, der in der Verriegelungsstellung des Schließbolzens 7 an dem Anschlag 29 anliegt.The locking bolt 7 preferably has a collar 24 at its end facing the collar 26, which collar bears against the stop 29 in the locking position of the locking bolt 7.

Nach Erreichen der Verriegelungsstellung des Schließbolzens 7 bzw. des Anschlags 29 wird durch weiteres Vorschieben des Antriebsbolzens 8 das Federelement 6 gestaucht.After the locking position of the locking bolt 7 or the stop 29 has been reached, the spring element 6 is compressed by further advancement of the drive bolt 8.

Die Rampe 19 am vorderen Ende des Antriebsbolzens 8 kommt dabei in Eingriff mit der Schrägführung 20 des Sperrelements 10 und verschiebt mit der Weiterbewegung des Antriebsbolzen 8 in Schließrichtung x das Sperrelement 10 von der Neutralstellung, gezeigt in Figur 5, in die aus der Öffnung 16 in der Mantelfläche 23 des Schließbolzens 7 vorstehende Sperrstellung, wie sie in Figur 2 dargestellt ist.The ramp 19 at the front end of the drive pin 8 comes into engagement with the oblique guide 20 of the locking element 10 and, with the further movement of the drive pin 8 in the closing direction x, shifts the locking element 10 from the neutral position, shown in FIG Figure 5 , into the opening 16 in the lateral surface 23 of the locking bolt 7 protruding locking position, as in Figure 2 is shown.

Beim Entriegeln der Schiebetür 2 wird beim Zurückziehen des Antriebsbolzens 8 entgegen der Schließrichtung zunächst das Sperrelement 10 zurück in die Neutralstellung verschoben, um ein anschließendes Zurückschieben des Schließbolzens 7 aus der Bolzenaufnahme 30 der Schiebetür 2 zu ermöglichen.When the sliding door 2 is unlocked, the locking element 10 is first moved back into the neutral position when the drive bolt 8 is pulled back against the closing direction, in order to then enable the locking bolt 7 to be pushed back out of the bolt receptacle 30 of the sliding door 2.

Beim weiteren Zurückbewegen des Antriebsbolzens 8 entgegen der Schließrichtung x wird durch die Kopplung des Antriebsbolzens 8 mit dem Schließbolzen 7 durch den Sicherungsstift 22 der Schließbolzen 7 zusammen mit dem Antriebsbolzen 8 weiter entgegen der Schließrichtung x zurück in die Freigabestellung, wie in Figur 4 gezeigt ist, verfahren.When the drive bolt 8 moves back against the closing direction x, the coupling of the drive bolt 8 with the locking bolt 7 through the locking pin 22 of the locking bolt 7 together with the drive bolt 8 further against the closing direction x returns to the release position, as in Figure 4 is shown.

Das Gehäuse des Verschlusssystems besteht bevorzugt aus zumindest zwei Bauteilen, wobei in einem ersten Gehäuseteil 3 zumindest der Elektromotor 9 aufgenommen ist und die zuvor erwähnte, in die Bohrung des hier als Schiebetür 1 ausgeführten Wandelements vorstehende Führung 27 an einem zweiten Gehäuseteil 4 angeformt ist. Das zweite Gehäuseteil 4 ist des Weiteren an der der Schiebetür 2 abgewandten Seite der Schiebetür 1 befestigt.The housing of the locking system preferably consists of at least two components, with at least the electric motor 9 being accommodated in a first housing part 3 and the aforementioned guide 27 protruding into the bore of the wall element designed here as a sliding door 1 being formed on a second housing part 4. The second housing part 4 is further attached to the side of the sliding door 1 facing away from the sliding door 2.

Die Betätigung des Verschlusssystems erfolgt bevorzugt über eine (nicht dargestellte) Steuereinheit, die einen aktiven Transponder wie beispielsweise RFID-, RC- oder Bluetooth-Transponder aufweist, die über eine entsprechende Sendereinheit betätigbar ist.The locking system is preferably actuated via a control unit (not shown) which has an active transponder, such as an RFID, RC or Bluetooth transponder, which can be actuated via a corresponding transmitter unit.
