Description

Die vorliegende Erfindung betrifft eine Möbeldrehtürautomatik zum automatischen Öffnen oder Schließen mindestens einer um eine Scharnierachse schwenkbaren Möbeltür, wobei ein Motor, vorzugsweise ein Elektromotor, als Antriebsmittel vorgesehen ist, der über Endschalter sowohl bei völlig geschlossener wie auch bei völlig geöffneter Möbeltür ausschaltbar ist und mit einer Rutschkupplung versehen ist.The present invention relates to a Möbeldrehürautomatik for automatically opening or closing at least one pivotable about a hinge axis furniture door, wherein a motor, preferably an electric motor, is provided as a drive means which is switched off via limit switch both fully closed and completely open furniture door and with a Slip clutch is provided.

Einrichtungen zum motorisch angetriebenen Öffnen und Schließen von Möbelerementen, z.B. von Möbeltüren, sind an sich bekannt.Means for motor-driven opening and closing of furniture elements, e.g. of furniture doors, are known per se.

Sicherheitseinrichtungen, die bei einer Blockade oder bei einer Überlastung des im Betrieb befindlichen Antriebes ein Abschalten des Motors oder eine Umkehr der Motorbewegung hervorrufen, gehören zum allgemein bekannten Stand der Technik.Safety devices that cause a shutdown of the engine or a reversal of the motor movement in a blockade or overload of the drive in operation, belong to the well-known prior art.

Aus Gründen der Einheitlichkeit der Möbelfront rüsten Möbelhersteller auch motorisch angetriebene Verschlusselemente, wie z.B. Möbeltüren, mit Griffen, Handhaben, Knöpfen oder dergleichen aus, wie sie nicht motorisch antreibbare Möbelelemente zum Zwecke des Öffnens oder Schließens benötigen.For reasons of uniformity of the furniture front, furniture manufacturers also equip motor-driven closure elements, such as e.g. Furniture doors, with handles, handles, buttons or the like, as they require non-motorized furniture elements for the purpose of opening or closing.

Somit ist von außen nicht erkennbar, ob und gegebenenfalls welches Möbelelement motorisch betätigbar ist.Thus, it is not apparent from the outside, if and if so which furniture element is operated by a motor.

Wird nun versucht, ein Möbelelement, beispielsweise eine Möbeltür, mit einem motorischen Antrieb manuell zu öffnen oder zu schließen, besteht die Gefahr, dass aufgrund der Haltekräfte des stillstehenden Antriebes manuelle Betätigungselemente wie z. B. Handhaben, Griffe oder dergleichen oder der Antrieb selbst durch überhöhte, von außen aufgebrachte Kräfte zerstört oder beschädigt werden.If an attempt is now made to manually open or close a furniture element, for example a furniture door, with a motor drive, there is a risk of manual actuation elements due to the holding forces of the stationary drive such as As handling, handles or the like or the drive itself are destroyed or damaged by excessive, applied from the outside forces.

Aus der DE 11 28 325 B ist eine Antriebsvorrichtung für Flügel von Türen bekannt geworden, die einen Motor, vorzugsweise einen Elektromotor aufweist, der über eine Rutschkupplung eine Antriebswelle antreibt und durch Endlagenschalter abschaltbar ist.From the DE 11 28 325 B is known a drive device for wings of doors, which has a motor, preferably an electric motor which drives a drive shaft via a slip clutch and can be switched off by limit switches.

Diese bekannte Antriebsvorrichtung ist eindeutig ausschließlich für Gebäude-Türen konzipiert und für Möbeltüren völlig ungeeignet.This known drive device is clearly designed exclusively for building doors and completely unsuitable for furniture doors.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Möbeldrehtürautomatik der gattungsgemäßen Art zu schaffen, die durch einfache und preiswerte konstruktive Maßnahmen so gestaltet ist, dass eine manuelle Betätigung einer Möbeltür ohne jedwede Beschädigungsgefahr auch dann möglich ist, wenn sich der antreibende Motor in Ruhestellung befindet, wobei auch eine manuelle Betätigung bei laufendem Antrieb ohne Beschädigungsgefahr möglich sein soll.The present invention has for its object to provide a Möbeldrehtürautomatik of the generic type, which is designed by simple and inexpensive design measures so that a manual operation of a furniture door without any risk of damage is also possible when the driving motor is at rest, although a manual operation while the drive is running should be possible without risk of damage.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass über den Elektromotor eine Schreibe antreibbar ist, an welcher ein Ende eines Pleuels gelagert ist, dessen anderes Ende in einer Linearführung geführt und mit einem Schubgestänge verbunden ist, welches seinerseits an einer Möbeltür angeschlossen ist und aus zwei kraftschlüssig miteinander verbundenen und nach einer Trennung der kraftschlüssigen Verbindung teleskopartig gegeneinander verschiebbaren Baugruppen besteht.This object is achieved in that a write is driven via the electric motor, to which one end of a connecting rod is mounted, the other end is guided in a linear guide and connected to a push rod, which in turn is connected to a furniture door and two non-positively interconnected and after a separation of the non-positive connection telescopically against each other slidable assemblies.

Eine derartige Möbeldrehtürautomatik bietet den Vorteil, dass neben der bekannten Öffnung und Schließung einer Möbeltür durch motorischen Antrieb jederzeit auch eine manuelle Betätigung der Möbeltür möglich ist, ohne dass hierbei eine Beschädigungsgefahr gegeben ist. Wird z. B. die Möbeltür bei stillstehendem Antrieb manuell betätigt, so wird je nach Betätigungsrichtung entweder die Rutschkupplung des Motors oder die Möglichkeit der Trennung der kraftschlüssigen Verbindung der Baugruppen des Schubgestänges genutzt, um die Möbeltür öffnen oder schließen zu können. Selbst bei laufendem Antrieb kann durch manuelle Krafteinwirkung entweder die Möbeltür entgegen der Antriebsrichtung des Motors betätigt oder in der gleichen Bewegungsrichtung beschleunigt, geöffnet oder geschlossen werden, ohne daß hiermit eine Beschädigungsgefahr für den Antrieb selbst oder für an der Möbeltür vorgesehene Griffteile oder dergleichen gegeben ist.Such Möbeldrehürautomatik offers the advantage that in addition to the known opening and closing of a furniture door by motor drive at any time a manual operation of the furniture door is possible without this is a risk of damage. If z. For example, if the furniture door is manually operated when the drive is stationary, either the friction clutch of the motor or the possibility of separating the frictional connection of the subassemblies of the thrust rod is used, depending on the direction of actuation, to open or close the furniture door to be able to. Even when the drive is running can be operated by manual force either the furniture door against the drive direction of the motor or accelerated in the same direction of movement, opened or closed without hereby a risk of damage to the drive itself or provided for the furniture door handle parts or the like.

Weitere Merkmale der Erfindung sind Gegenstand von Unteransprüchen.Further features of the invention are the subject of dependent claims.

Ein Ausführungsbeispiel der Erfindung ist in den beigefügten Zeichnungen dargestellt und wird im folgenden näher beschrieben.An embodiment of the invention is illustrated in the accompanying drawings and will be described in more detail below.

FIG. 2
a detailed drawing of a push rod of Möbeldrehürautomatik according to Figure 1.

In Figur 1 ist mit dem Bezugszeichen 1 insgesamt eine Möbeldrehtürautomatik zum automatischen Öffnen oder Schließen mindestens einer um eine Scharnierachse 2 schwenkbaren Möbeltür 3 bezeichnet.In FIG. 1, reference numeral 1 denotes a furniture turntable automatic for automatic opening or closing of at least one furniture door 3 pivotable about a hinge axis 2.

Im dargestellten Ausführungsbeispiel sind mittels der Möbeldrehtürautomatik 1 zwei nebeneinander liegende Möbeltüren 3 automatisch zu öffnen oder zu schließen.In the illustrated embodiment, two furniture doors 3 next to each other are automatically opened or closed by means of the furniture turntable 1.

Die Möbeldrehtürautomatik 1 umfaßt einen Motor, vorzugsweise einen Elektromotor 4, mit einer bekannten und insoweit nicht dargestellten Rutschkupplung, eine vom Elektromotor 4 antreibbare Riemenscheibe 5, die über einen Antriebsriemen 6, beispielsweise in Form einer Rundschnur, über den Elektromotor 4 antreibbar ist. Weiterhin umfaßt die Möbeldrehtürautomatik 1 ein Pleuel 7, welches mit einem seiner Enden auf der Riemenscheibe 5 gelagert und mit seinem anderen Ende in einer Linearführung 8 geführt und mit zwei Schubgestängen 9 verbunden ist.The furniture turntable 1 comprises a motor, preferably an electric motor 4, with a known and so far not shown, a driven by the electric motor 4 pulley 5, which is drivable via a drive belt 6, for example in the form of a round cord, via the electric motor 4. Furthermore, the furniture turntable 1 comprises a connecting rod 7, which with a its ends mounted on the pulley 5 and guided at its other end in a linear guide 8 and connected to two push rods 9.

Die Schubgestänge 9 sind ihrerseits jeweils an einer der beiden Möbeltüren 3 schwenkbar angeschlossen.The push rods 9 are in turn connected to one of the two furniture doors 3 pivotally.

Figur 2 zeigt den Aufbau der erwähnten Schubgestänge 9 in detaillierter Darstellung.Figure 2 shows the structure of the mentioned push rod 9 in a detailed representation.

Es wird erkennbar, daß jedes Schubgestänge 9 aus zwei Baugruppen 9a und 9b besteht, wobei diese beiden Baugruppen 9a und 9b kraftschlüssig miteinander verbunden und nach Trennung dieser kraftschlüssigen Verbindung teleskopartig gegeneinander verschiebbar sind.It will be appreciated that each push linkage 9 consists of two subassemblies 9a and 9b, these two subassemblies 9a and 9b being non-positively connected to one another and being telescopically displaceable against each other after separation of this non-positive connection.

Im dargestellten Ausführungsbeispiel besteht die Baugruppe 9a im wesentlichen aus einem Rohr 10 und die Baugruppe 9b im wesentlichen aus einer Stange 11 mit einem Kolben 12, der innerhalb des Rohres 10 längs verschiebbar geführt ist und einen federbelasteten Schnäpper 13 aufweist. Der federbelastete Schnäpper 13 verbindet oder verriegelt im normalen Betriebszustand die beiden Baugruppen 9a und 9b gegeneinander kraftschlüssig. Nach Aufhebung dieser kraftschlüssigen Verbindung kann die Stange 11 mit dem Kolben 12 gegenüber dem Rohr 10 in Längsrichtung teleskopartig verschoben werden.In the illustrated embodiment, the assembly 9a consists essentially of a tube 10 and the assembly 9b substantially of a rod 11 with a piston 12 which is guided longitudinally displaceably within the tube 10 and has a spring-loaded catch 13. The spring-loaded catch 13 connects or locks in the normal operating state, the two modules 9a and 9b against each other non-positively. After cancellation of this non-positive connection, the rod 11 can be telescoped with the piston 12 relative to the tube 10 in the longitudinal direction.

Wie Figur 2 weiterhin zeigt, ist das Rohr 10 an seinem dem Kolben 12 angewandten Ende mit einem Rohrboden 14 versehen, innerhalb dieses Rohrbodens 14 ist ein Verbindungselement 15 zur Verbindung des kompletten Schubgestänges 9 mit einer Möbeltür 3 versehen. Zwischen dem Rohrboden 14 und dem Kolben 12 ist ein Magnet 16 angeordnet.As Figure 2 also shows, the tube 10 is provided at its end applied to the piston 12 with a tube plate 14, within this tube plate 14 is a connecting element 15 for connecting the complete push rod 9 is provided with a furniture door 3. Between the tube sheet 14 and the piston 12, a magnet 16 is arranged.

Die Funktion der Möbeldrehtürautomatik 1 gemäß vorliegender Konstruktionsbeschreibung ist wie folgt:The function of the furniture turning mechanism 1 according to the present design description is as follows:

Wird der Elektromotor 4 eingeschaltet, so bewegt sich je nach Drehrichtung des Elektromotors 4 die Riemenscheibe im Uhrzeiger- oder im Gegenuhrzeigersinn. Entsprechend wird das Pleuel 7 in der Linearführung 8 vor- und zurückbewegt.If the electric motor 4 is turned on, the pulley moves clockwise or counterclockwise, depending on the direction of rotation of the electric motor 4. Accordingly, the connecting rod 7 is moved back and forth in the linear guide 8.

In Figur 1 ist die Möbeldrehtürautomatik 1 in einer Grund- oder Schließstellung der Möbeltüren 3 dargestellt. In dieser Grundstellung weist der Anlenkpunkt 7a des Pleuels 7 auf der Riemenscheibe 5 den größten Abstand zu den Möbeltüren 3 auf.In Figure 1, the Möbeldrehtürautomatik 1 is shown in a basic or closed position of the furniture doors 3. In this basic position, the pivot point 7a of the connecting rod 7 on the pulley 5 on the largest distance to the furniture doors 3.

Wird aus dieser Position heraus durch Einschalten des Elektromotors 4 die Riemenscheibe 5 gedreht, so bewegt sich das Pleuel 7 innerhalb der Linearführung 8 in Richtung der Möbeltüren 3.If the pulley 5 is rotated out of this position by switching on the electric motor 4, the connecting rod 7 moves within the linear guide 8 in the direction of the furniture doors 3.

Über die mit dem Pleuel 7 verbundenen Schubgestänge 9 werden infolge dieser Verschiebebewegung beide Möbeltüren 3 in Öffnungsrichtung verschwenkt, bis die endgültige Öffnungsstellung erreicht und der Elektromotor 4 über einen entsprechenden Endschalter abgeschaltet wird.As a result of this displacement movement, both furniture doors 3 are pivoted in the opening direction via the connecting rod 9 connected to the connecting rod 7 until the final open position is reached and the electric motor 4 is switched off via a corresponding limit switch.

Wird nun zum Zwecke des Schließens der Möbeltüren 3 der Elektromotor 4 in entgegengesetzter Richtung in Drehbewegung versetzt, so bewegt sich aufgrund der Drehbewegung der Riemenscheibe 5 das Pleuel 7 wieder in seine ursprüngliche Ausgangsstellung zurück, entsprechend werden über das Zurückziehen der Schubgestänge 9 die beiden Möbeltüren 3 wieder in ihre Schließstellung gemäß Figur 1 verschwenkt.If, for the purpose of closing the furniture doors 3, the electric motor 4 is set in rotational motion in the opposite direction, the connecting rod 7 moves back to its original starting position due to the rotational movement of the pulley 5, and the two furniture doors 3 are correspondingly retracted via the pulling rod 9 pivoted back into its closed position shown in FIG.

Sofern versucht wird, eine oder beide Möbeltüren 3 aus der Grundstellung gemäß Figur 1 heraus manuell zu öffnen, erfolgt eine Trennung der beiden Baugruppen 9a und 9b im Sinne einer Überwindung der kraftschlüssigen Verbindung durch den Schnäpper 13, so daß nun die beiden Baugruppen 9a und 9b teleskopartig gegeneinander verschoben werden können.If an attempt is made to manually open one or both furniture doors 3 from the basic position according to FIG. 1, the two subassemblies 9a and 9b are separated in the sense of overcoming the frictional connection by the catch 13, so that now the two subassemblies 9a and 9b can be telescoped against each other.

Die Möbeltüren 3 können somit ohne Beschädigungsgefahr auch manuell vollständig geöffnet werden. Anschließend können die Möbeltüren 3 auch manuell wieder in Schließlage zurückbewegt werden, wobei dann wieder eine kraftschlüssige Verbindung zwischen den beiden Baugruppen 9a und 9b erfolgt durch Einrasten des Schnäppers 13. Ebenfalls ist es denkbar, die Verbindung der beiden Baugruppen 9a und 9b dadurch wieder herzustellen, daß der Elektromotor 4 im Sinne einer Öffnungsbewegung eingeschaltet wird. Das Pleuel 7 wird dann entsprechend der oben beschriebenen Öffnungsbewegung bewegt und die Stangen 11 der Schubgestänge 9 werden praktisch "im Leerlauf" in die Rohre 10 zurückgeschoben, bis durch Einrasten der Schnäpper 13 wieder die kraftschlüssige Verbindung hergestellt ist. Nunmehr kann wiederum durch weitere Betätigung des Elektromotors 4 im Sinne einer Schließbewegung eine motorische Schließung der Möbeltüren 3 erfolgen.The furniture doors 3 can thus be fully opened manually without risk of damage. Subsequently, the furniture doors 3 can also be manually moved back into the closed position, in which case again a non-positive connection between the two modules 9a and 9b takes place by snapping the Schnäppers 13. It is also conceivable to restore the connection of the two modules 9a and 9b in that the electric motor 4 is turned on in the sense of an opening movement. The connecting rod 7 is then moved in accordance with the opening movement described above and the rods 11 of the push rod 9 are practically pushed back into the tubes 10 "idle" until the frictional connection is made by snapping the catch 13 again. Now, in turn, by further actuation of the electric motor 4 in the sense of a closing movement, a motorized closure of the furniture doors 3 take place.

Sofern die beiden Möbeltüren 3 durch Betätigung des Elektromotors 4 motorisch geöffnet worden sind, kann durch manuelles Betätigen auch das Schließen der beiden Möbeltüren 3 erfolgen, da dies durch die im Elektromotor 4 eingebaute Rutschkupplung ohne Beschädigungsgefahr für den Motor oder andere Teile des Antriebes denkbar und möglich ist.If the two furniture doors 3 have been opened by motor actuation of the electric motor 4, can be done by manually pressing the closing of the two furniture doors 3, as this conceivable and possible by the built-in electric motor 4 slip clutch without risk of damage to the engine or other parts of the drive is.

Beim dargestellten Ausführungsbeispiel ist die Konstruktion so ausgelegt, daß die beiden Baugruppen 9a und 9b der Schubgestänge 9 dann teleskopartig gegeneinander verschoben werden, wenn hiermit ein Öffnen der Möbeltüren 3 erfolgt. Umgekehrt wird beim dargestellten Ausführungsbeispiel die Rutschkupplung des Elektromotors 4 genutzt, um alle Bauteile der Möbeldrehtürautomatik aus einer motorisch herbeigeführten Offenstellung manuell in eine Schließstellung zurückbewegen zu können.In the illustrated embodiment, the construction is designed so that the two modules 9a and 9b of the push rod 9 are then telescoped against each other, if this is done opening the furniture doors 3. Conversely, in the illustrated embodiment, the slip clutch of the electric motor 4 is used to manually move all components of Möbeldrehürautomatik from a motor-induced open position to a closed position.

Selbstverständlich kann hier auch eine Umkehr dieser Verhältnisse erfolgen, d. h., die Schubgestänge 9 können so ausgelegt sein, daß diese beim Schließvorgang bezüglich ihrer kraftschlüssigen Verbindung der beiden Baugruppen 9a und 9b voneinander getrennt und teleskopartig gegeneinander verschoben werden, während ein manuelles Öffnen der Möbeltüren 3 durch Überwindung der Rutschkupplung herbeigeführt werden kann.Of course, a reversal of these conditions can take place here, d. h., The push rod 9 may be designed so that they are separated during the closing process with respect to their non-positive connection of the two modules 9 a and 9 b separated from each other and telescopically against each other, while a manual opening of the furniture doors 3 can be brought about by overcoming the slip clutch.

Durch den zwischen dem Rohrboden 14 und dem Kolben 12 jedes Schubgestänges 9 angeordneten Magneten 16 kann die Haltekraft zwischen den beiden Baugruppen 9a und 9b erhöht werden, ebenfalls kann durch den Magneten 16 beim Zusammenschieben der beiden Baugruppen 9a und 9b das sichere Einrasten des Schnäppers 13 unterstützt werden.By arranged between the tube sheet 14 and the piston 12 of each thrust rod 9 magnets 16, the holding force between the two modules 9a and 9b can be increased, also by the magnet 16 when pushed together the two modules 9a and 9b the secure engagement of the latch 13 are supported.

Der Elektromotor 4 kann durch Sensoren, durch eine Fernbedienung oder dergleichen betätigbar sein.The electric motor 4 can be actuated by sensors, by a remote control or the like.

Auch unter sicherheitstechnischen Gesichtspunkten bietet die erfindungsgemäße Möbeldrehtürautomatik 1 enorme Vorteile.Also from a safety point of view, the furniture turntable 1 according to the invention offers enormous advantages.

So kann beispielsweise eine Verletzungsgefahr beim motorischen Schließen der Möbeltüren 3 dadurch ausgeschlossen werden, daß die Rutschkupplung des Motors so eingestellt ist, daß die auf die Möbeltüren 3 einwirkenden Kräfte so gering sind, daß beispielsweise eine zwischen den beiden Möbeltüren 3 eingeklemmte Hand oder ein Arm einer Bedienungsperson nicht verletzt werden.Thus, for example, a risk of injury in the motorized closing of the furniture doors 3 be ruled out that the slip clutch of the engine is set so that the forces acting on the furniture doors 3 forces are so low that, for example, a clamped between the two furniture doors 3 hand or arm of a Operator will not be hurt.

Die Verbindung zwischen dem Pleuel 7 und den beiden Schubgestängen 9 erfolgt in einem Drehpunkt 16 auf einem Schiebeschlitten 17, wobei der Schiebeschlitten 17 in der schon erwähnten Linearführung 8 geführt ist.The connection between the connecting rod 7 and the two push rods 9 takes place in a pivot point 16 on a sliding carriage 17, wherein the sliding carriage 17 is guided in the already mentioned linear guide 8.
