Description

Elektromotorischer Möbelantrieb Electromotive furniture drive
Die Erfindung betrifft einen elektromotorischen Möbelantrieb der im Oberbegriff des Anspruchs 1 genannten Art zum Verstellen von Teilen eines Möbels relativ zueinander. Derartige Möbelantriebe sind allgemein bekannt, beispielsweise durch DE 9316465 Ul , und dienen beispielsweise zum Verstellen von Teilen eines Lattenrostes .The invention relates to an electromotive furniture drive of the type mentioned in the preamble of claim 1 for adjusting parts of a piece of furniture relative to one another. Furniture drives of this type are generally known, for example from DE 9316465 U1, and are used, for example, to adjust parts of a slatted frame.
Ein Nachteil des aus der DE 9316465 Ul bekannten Möbelantriebs besteht darin, daß die Antriebseinheit, die an dem Lattenrost montiert ist, ständig unter Spannung steht . Dies führt einerseits zu einem erhöhten Energieverbrauch, da die Antriebseinheit auch im Ruhezustand einen gewissen, wenn auch geringen Ruhestrom aufnimmt. Besonders nachteilig ist, daß ein Benutzer des bekannten Möbelantriebs ständig einem elektromagnetischem Feld ausgesetzt ist, wenn er auf einer mittels eines Lattenrostes abgestützten Matratze ruht. Dies um so mehr, als der Möbelantrieb unmittelbar an dem Lat- tenrost und damit in unmittelbarer Nähe des Körpers des Benutzers angeordnet ist. Weiterhin ist nachteilig, daß ein Transformator, der die Netzspannung auf eine Betriebsspannung des Möbelantriebs transformiert, ständig unter Spannung steht, was unter Umständen zu einem Brummen des Transformators führen kann, das insbesondere im Schlafbereich als störend empfunden wird. Aus diesem Grund ist es allgemein bekannt, Möbel- antriebe mit einer Netzfreischaltungseinrichtung auszustatten, wie sie beispielsweise aus DE 92 12 599 Ul bekannt ist . Durch DE 299 05 299 Ul ist ein Möbelantrieb der betreffenden Art bekannt, der eine Antriebseinheit aufweist, die in Montageposition mit einem zu verstellenden Teil des Möbels in Wirkungsverbindung steht, beispielsweise mit einem Kopfstützteil und/oder einem Fuß- stützteil eines Lattenrostes. Der bekannte Möbelantrieb weist ferner Steuermittel zu Ansteuerung der Antriebseinheit und Spannungsversorgungsmittel für die Antriebseinheit auf, wobei die Spannungsversorgungsmittel einen Transformator aufweisen. Ferner weist der bekann- te Möbelantrieb eine Netzfreischaltungseinrichtung auf, mittels derer wenigstens die Antriebseinheit spannungsfrei schaltbar ist.A disadvantage of the furniture drive known from DE 9316465 Ul is that the drive unit, which is mounted on the slatted frame, is constantly under tension. On the one hand, this leads to increased energy consumption, since the drive unit absorbs a certain, albeit low, quiescent current even in the idle state. It is particularly disadvantageous that a user of the known furniture drive is constantly exposed to an electromagnetic field when he rests on a mattress supported by a slatted frame. This is all the more so since the furniture drive is arranged directly on the slatted frame and thus in the immediate vicinity of the user's body. A further disadvantage is that a transformer that transforms the mains voltage to an operating voltage of the furniture drive is constantly under voltage, which under certain circumstances can lead to a hum of the transformer, which is perceived as disturbing, particularly in the sleeping area. For this reason, it is generally known to equip furniture drives with a mains isolation device, as is known, for example, from DE 92 12 599 U1. From DE 299 05 299 U1 a furniture drive of the type in question is known which has a drive unit which is in operative connection in the assembly position with a part of the piece of furniture to be adjusted, for example with a headrest part and / or a footrest part of a slatted frame. The known furniture drive also has control means for controlling the drive unit and voltage supply means for the drive unit, the voltage supply means having a transformer. Furthermore, the known furniture drive has a mains isolation device, by means of which at least the drive unit can be switched voltage-free.
Durch die Netzfreischaltungseinrichtung sind die oben geschilderten Nachteile vermieden, die dann ent- stehen, wenn die Antriebseinheit ständig unter Spannung steht .The mains isolation device avoids the disadvantages described above, which arise when the drive unit is constantly under voltage.
Bei dem bekannten Möbelantrieb ist zur Aufnahme der Netzfreischaltungseinrichtung eine mechanische Aufnahmeeinheit für eine Handbedienungseinrichtung, bei- spielsweise einen Handschalter, vorgesehen, wobei die Aufnähmeeinheit mechanische Mittel aufweist, durch die die Netzfreischaltungseinrichtung beim Ablegen der Handbedienungseinrichtung in der Aufnahmeeinheit aktivierbar und beim Herausnehmen der Handbedienungsein- richtung deaktivierbar ist.In the known furniture drive, a mechanical receiving unit for a manual control device, for example a hand switch, is provided for receiving the mains activation device, the receiving unit having mechanical means by which the mains activation device can be activated when the manual control device is placed in the receiving unit and when the manual control device is removed can be deactivated.
Ein Nachteil des bekannten Möbelantriebs besteht darin, daß er aufwendig im Aufbau und damit teuer in der Herstellung ist.A disadvantage of the known furniture drive is that it is complex to build and therefore expensive to manufacture.
Der Erfindung liegt die Aufgabe zugrunde, einen Möbelantrieb der im Oberbegriff des Anspruchs 1 genannten Art anzugeben, der die Nachteile des bekannten Möbelantriebs nicht aufweist, der also einfacher und damit kostengünstiger herstellbar ist. Diese Aufgabe wird durch die im Anspruch 1 angegebene Lehre gelöst .The invention has for its object a Specify furniture drive of the type mentioned in the preamble of claim 1, which does not have the disadvantages of the known furniture drive, which is therefore easier and therefore cheaper to manufacture. This object is achieved by the teaching specified in claim 1.
Der Erfindung liegt der Gedanke zugrunde, die zur Ansteuerung, Spannungsversorgung und Netzfreischaltung der Antriebseinheit erforderlichen Bauteile und Bau- gruppen soweit wie möglich räumlich zu konzentrieren und räumlich von der Antriebseinheit zu trennen. Hierzu sieht die Erfindung vor, daß die Steuermittel mit der Netzfreischaltungseinrichtung und/oder mit dem Transformator in einem gemeinsamen, von der Antriebseinheit räumlich getrennten Gehäuse aufgenommen und mit derThe invention is based on the idea of spatially concentrating as far as possible the components and assemblies required for actuation, voltage supply and disconnection of the drive unit and separating them spatially from the drive unit. For this purpose, the invention provides that the control means with the mains isolation device and / or with the transformer in a common, spatially separate from the drive unit and housed with the
Antriebseinheit über Steuer- und Spannungsversorgungsleitungen verbindbar sind.Drive unit can be connected via control and voltage supply lines.
Insbesondere dann, wenn sowohl die Netzfreischaltungseinrichtung als auch der Transformator in dem Ge- häuse aufgenommen sind, ist der erfindungsgemäße Möbel- antrieb im Vergleich zu dem bekannten Möbelantrieb wesentlich einfacher und damit kostengünstiger herstellbar, da zum einen eine separate mechanische Aufnahme- einheit und zum andern ein separates Steckernetzteil entfällt, da alle zur Ansteuerung, Spannungsversorgung und Netzfreischaltung der Antriebseinheit erforderlichen Bauteile und Baugruppen in einem gemeinsamen Gehäuse aufgenommen sind. Das gemeinsame Gehäuse läßt sich einfacher und damit kostengünstiger herstellen als ein separates Steckernetzteil und eine separate mechanische Aufnahmeeinheit .In particular when both the mains disconnection device and the transformer are accommodated in the housing, the furniture drive according to the invention is considerably simpler and thus less expensive to produce than the known furniture drive, since on the one hand a separate mechanical receiving unit and on the other hand A separate plug-in power supply unit is not required, since all the components and assemblies required to control, power supply and disconnect the drive unit are housed in a common housing. The common housing can be manufactured more simply and therefore more cost-effectively than a separate plug-in power supply and a separate mechanical receiving unit.
Grundsätzlich ist es erfindungsgemäß auch möglich, entweder nur die Netzfreischaltungseinrichtung oder nur den Transformator in dem gemeinsamen Gehäuse aufzuneh- men. Gleichwohl ergibt sich auch bei diesen Aus- führungsformen eine gegenüber dem Stand der Technik einfachere und damit kostengünstigere Herstellung.In principle, it is also possible in accordance with the invention to accommodate only the mains isolation device or only the transformer in the common housing. men. Nevertheless, this embodiment also results in a simpler and therefore less expensive production compared to the prior art.
Ein besonderer Vorteil der erfindungsgemäßen Lehre besteht darin, daß die Montage des erfindungsgemäßen Möbelantriebs äußerst einfach gestaltet ist . Nach dem Anbringen der Antriebseinheit an dem zu verstellenden Möbel, beispielsweise einem Lattenrost, ist es lediglich noch erforderlich, die Antriebseinheit mit den Steuer- und Spannungsversorgungsleitungen zu verbinden und einen mit dem Gehäuse verbundenen Netzstecker in eine Steckdose einzustecken. Dementsprechend ist auch eine Demontage des Möbelantriebs vereinfacht.A particular advantage of the teaching according to the invention is that the assembly of the furniture drive according to the invention is extremely simple. After the drive unit has been attached to the piece of furniture to be adjusted, for example a slatted frame, it is only necessary to connect the drive unit to the control and voltage supply lines and to plug a power plug connected to the housing into a socket. Accordingly, disassembly of the furniture drive is simplified.
Ein weiterer Vorteil der erfindungsgemäßen Lehre besteht darin, daß weniger räumlich voneinander getrennte Baugruppen vorhanden sind, die in der Nähe der Antriebseinheit, beispielsweise auf einem Nachttisch, abgelegt werden müssen. Auf diese Weise ist der erfindungsgemäße Möbelantrieb optisch ansprechender gestal- tet.Another advantage of the teaching according to the invention is that there are fewer spatially separate assemblies which have to be placed near the drive unit, for example on a bedside table. In this way, the furniture drive according to the invention is visually more appealing.
Eine Weiterbildung der erfindungsgemäßen Lehre sieht vor, daß die Netzfreischaltungseinrichtung Schaltermittel aufweist, mittels derer wenigstens die Antriebseinheit spannungsfrei schaltbar ist, daß das Ge- häuse einen Ablagebereich für einen Handschalter zurA further development of the teaching according to the invention provides that the mains isolation device has switch means by means of which at least the drive unit can be switched voltage-free, that the housing has a storage area for a hand switch
Betätigung der Steuermittel aufweist und daß die Schaltermittel derart ausgebildet sind, daß die Schaltermittel bei auf dem Gehäuse abgelegtem Handschalter die Antriebseinheit spannungsfrei schalten. Bei dieser Aus- führungsform wird wenigstens die Antriebseinheit automatisch spannungsfrei geschaltet, wenn der Handschalter auf dem Gehäuse abgelegt wird.Has actuation of the control means and that the switch means are designed such that the switch means switch the drive unit voltage-free when the hand switch is placed on the housing. In this embodiment, at least the drive unit is automatically disconnected from the power supply when the hand switch is placed on the housing.
Eine vorteilhafte Weiterbildung der vorgenannten Ausführungsform sieht vor, daß die Schaltermittel ein mechanisches Betätigungselement aufweisen, das in dem Ablagebereich für den Handschalter an dem Gehäuse angeordnet ist, und daß das Betätigungselement in einer Einschaltposition, in der die Spannungsversorgung der Antriebseinheit eingeschaltet ist, zu der Außenfläche des Gehäuses hin so weit hervorsteht, daß das Betätigungselement beim Ablegen des Handschalters in eine Ausschaltposition bewegbar ist, in der die Antriebseinheit durch die Schaltermittel spannungsfrei geschaltet ist. Bei dieser Ausführungsform sind die mechanischen Betätigungsmittel zur Betätigung der Schaltermittel in das Gehäuse integriert. Auf diese Weise ist die Herstellung weiter vereinfacht und somit noch kostengünstiger gestaltet. Um zu gewährleisten, daß die Netzfreischaltungseinrichtung deaktiviert ist, wenn der Handschalter nicht in dem Ablagebereich des Gehäuses abgelegt ist, ist es zweckmäßig, daß das Betätigungselement durch Federmittel in die Einschaltposition vorgespannt ist. Um die Herstellung noch weiter zu vereinfachen und damit noch kostengünstiger zu gestalten, ist es zweckmäßig, daß das Betätigungselement durch eine Taste gebildet ist.An advantageous development of the aforementioned embodiment provides that the switch means Have mechanical actuating element, which is arranged in the storage area for the hand switch on the housing, and that the actuating element in a switch-on position, in which the power supply of the drive unit is switched on, protrudes so far towards the outer surface of the housing that the actuating element when the Manual switch can be moved into a switch-off position, in which the drive unit is switched voltage-free by the switch means. In this embodiment, the mechanical actuation means for actuating the switch means are integrated in the housing. In this way, the production is further simplified and thus made even more cost-effective. In order to ensure that the mains disconnection device is deactivated when the hand switch is not placed in the storage area of the housing, it is expedient for the actuating element to be biased into the switch-on position by spring means. In order to simplify the production even further and thus to make it even more cost-effective, it is expedient for the actuating element to be formed by a button.
Eine besonders einfache und damit kostengünstig herstellbare Ausführungsform sieht vor, daß das Betätigungselement durch eine einstückig an eine Außenfläche des Gehäuses angeformte, elastisch verformbare Zunge gebildet ist. Unterhalb dieser Zunge kann beispielsweise ein mechanischer Schalter in dem Gehäuse angeord- net sein, der bei elastischer Verformung der Zunge durch diese betätigt wird, wenn der Handschalter auf dem Gehäuse abgelegt wird.A particularly simple and thus inexpensive to produce embodiment provides that the actuating element is formed by an elastically deformable tongue integrally formed on an outer surface of the housing. Below this tongue, for example, a mechanical switch can be arranged in the housing, which is actuated by the tongue when the tongue is elastically deformed when the manual switch is placed on the housing.
Um den Handschalter in der abgelegten Position an dem Gehäuse zu fixieren ist es zweckmäßig, daß Halte- mittel zum Halten des Handschalters an dem Gehäuse in Ablageposition des Handschalters vorgesehen sind.In order to fix the hand switch in the stored position on the housing, it is expedient that means are provided for holding the hand switch on the housing in the storage position of the hand switch.
Bei der vorgenannten Ausführungsform können die Haltemittel in beliebiger geeigneter Weise ausgebildet sein. Eine zweckmäßige Weiterbildung sieht vor, daß die Haltemittel Klemm- und/oder Rastmittel aufweisen. Derartige Klemm- und/oder Rastmittel sind einfach in das Gehäuse integrierbar und gewährleisten, daß der Handschalter in der Ablageposition sicher an dem Gehäuse gehalten ist.In the aforementioned embodiment, the holding means can be designed in any suitable manner. An expedient development provides that the holding means have clamping and / or latching means. Such clamping and / or latching means can be easily integrated into the housing and ensure that the hand switch is securely held on the housing in the storage position.
Eine Ausführungsform der Haltemittel sieht vor, daß die Haltemittel an einem Ende des Ablagebereiches ein Halteteil aufweisen, das in Ablageposition des Handschalters ein Ende des Handschalters formschlüssig übergreift, und daß im Bereich des anderen Endes des Ablagebereiches wenigstens ein Vorsprung vorgesehen ist, der in Ablageposition des Handschalters in eine an dem Handschalter vorgesehenen Ausnehmung klemmend oder rastend eingreift. Bei dieser Ausführungsform können das Halteteil und der Vorsprung einstückig an das Gehäuse angeformt sein, was die Herstellung wesentlich vereinfacht .One embodiment of the holding means provides that the holding means have at one end of the storage area a holding part which positively engages over one end of the hand switch in the storage position of the hand switch, and that at least one projection is provided in the area of the other end of the storage area which is in the storage position of the Hand switch engages in a recess provided on the hand switch by clamping or latching. In this embodiment, the holding part and the projection can be integrally formed on the housing, which considerably simplifies production.
Grundsätzlich ist es ausreichend, wenn mittels der Netzfreischaltungseinrichtung die Antriebseinheit oder die Antriebseinheiten spannungsfrei schaltbar ist bzw. sind. Eine besonders vorteilhafte Weiterbildung sieht vor, daß der Möbelantrieb durch die Netzfreischaltungseinrichtung galvanisch vom Netz trennbar ist. Bei dieser Ausführungsform ist bei aktivierter Netzfreischal- tung der gesamte Möbelantrieb spannungsfrei geschaltet, so daß von den Bauteilen des Möbelantriebs keinerlei elektromagnetische Felder mehr erzeugt werden.Basically, it is sufficient if the drive unit or the drive units can be switched without voltage by means of the mains isolation device. A particularly advantageous development provides that the furniture drive can be galvanically separated from the network by the mains isolation device.
