Abstract
Description
Die Erfindung betrifft einen elektromotorischen Doppelantrieb der im Oberbegriff des Anspruchs 1 genannten Art zum Verstellen von Stützteilen einer Stützeinrichtung zum Abstützen einer Polsterung eines Sitz- und/oder Liegemöbels, insbesondere eines Lattenrostes, relativ zueinander.The invention relates to an electric motor double drive referred to in the preamble of claim 1 for adjusting support parts of a support means for supporting a padding of a sitting and / or reclining furniture, in particular a slatted frame, relative to each other.
Derartige Doppelantriebe sind allgemein bekannt und dienen beispielsweise zum Verstellen von Stützteilen eines Lattenrostes. Die bekannten Doppelantriebe weisen wenigstens zwei in einem gemeinsamen Antriebsgehäuse aufgenommene Antriebseinheiten auf, die mit einer netzgebundenen Spannungsquelle verbindbar oder verbunden sind, Um die Antriebseinheiten bei Nichtbenutzung vom Stromnetz zu trennen, weisen die bekannten Doppelantriebe eine Netzfreischaltungseinrichtung zur Netzfreischaltung der Antriebseinheiten auf.Such double drives are well known and are used for example for adjusting support parts of a slatted frame. The known double drives have at least two recorded in a common drive housing drive units which are connected or connected to a network-connected voltage source To separate the drive units when not in use from the mains, the known double drives have a mains isolation device for mains isolation of the drive units.
Der Erfindung liegt die Aufgabe zugrunde, einen elektromotorischen Doppelantrieb der im Oberbegriff des Anspruchs 1 genannten Art anzugeben, der einfach aufgebaut ist.The invention has for its object to provide an electric motor double drive referred to in the preamble of claim 1 species, which is simple.
Diese Aufgabe wird durch die im Anspruch 1 angegebene Erfindung gelöst.This object is achieved by the invention defined in claim 1.
Die Erfindung sieht vor, daß die netzgebundene Spannungsquelle ein Schaltnetzteil aufweist, das mit der Netzfreischaltungseinrichtung in einem gemeinsamen Gehäuse aufgenommen ist.The invention provides that the network-connected voltage source has a switched-mode power supply, which is connected to the mains isolation device in a common Housing is added.
Auf diese Weise bildet das Schaltnetzteil mit der Netzfreischaltungseinrichtung eine bauliche Einheit, so daß der Doppelantrieb in seinem Aufbau vereinfacht ist.In this way, the switching power supply with the mains isolation device forms a structural unit, so that the double drive is simplified in its construction.
Da sich erfindungsgemäß somit separate Gehäuse für das Schaltnetzteil einerseits und die Netzfreischaltungseinrichtung andererseits erübrigen, ist der erfindungsgemäße Doppelantrieb besonders kostengünstig herstellbar.Since according to the invention thus separate housing for the switching power supply on the one hand and the power cut-off device on the other hand unnecessary, the double drive according to the invention is particularly inexpensive to produce.
Eine vorteilhafte Weiterbildung der Erfindung sieht vor, daß das Gehäuse in dem Antriebsgehäuse aufgenommen ist. Bei dieser Ausführungsform ist der Doppelantrieb besonders einfach aufgebaut. Er besteht im einfachsten Falle noch aus dem Antriebsgehäuse, in dem sämtliche Antriebskomponenten und elektrische sowie elektronische Komponenten aufgenommen sind. Über eine Netzzuleitung wird das Antriebsgehäuse zur Speisung der elektrischen bzw. elektronischen Komponenten mit einem Stromnetz verbunden. Die Ansteuerung des Doppelantriebs erfolgt in herkömmlicher Weise über einen Handschalter.An advantageous development of the invention provides that the housing is accommodated in the drive housing. In this embodiment, the double drive is particularly simple. In the simplest case, it still consists of the drive housing in which all drive components and electrical and electronic components are accommodated. Via a mains supply line, the drive housing is connected to a power supply system for supplying the electrical or electronic components. The control of the double drive takes place in a conventional manner via a manual switch.
Eine andere vorteilhafte Weiterbildung der Erfindung sieht vor, daß das Gehäuse außerhalb des Antriebsgehäuses angeordnet ist. Bei dieser Ausführungsform besteht hinsichtlich der räumlichen Anordnung des Gehäuses, in dem das Schaltnetzteil und die Netzfreischaltungseinrichtung aufgenommen sind, relativ zu dem Antriebsgehäuse eine hohe Flexibilität. Ein weiterer Vorteil dieser Ausführungsform besteht darin, daß der Doppelantrieb bei Aktivierung der Netzfreischaltung bereits entfernt von dem Antriebsgehäuse stromlos geschaltet werden kann. Das Antriebsgehäuse enthält dann keinerlei stromführende Bauteile mehr.Another advantageous embodiment of the invention provides that the housing is arranged outside of the drive housing. In this embodiment, with respect to the spatial arrangement of the housing in which the switching power supply and the power cut-off device are accommodated, there is a high flexibility relative to the drive housing. Another advantage of this embodiment is that the double drive can already be disconnected from the drive housing deenergized when activating the power cut. The drive housing then no longer contains any current-carrying components.
Eine vorteilhafte Weiterbildung der vorgenannten Ausführungsform sieht vor, daß das Gehäuse in einer zu dem Antriebsgehäuse führenden und die Antriebseinheiten mit einem Stromnetz verbindenden Netzzuleitung angeordnet ist. Bei dieser Ausführungsform erfolgt die Netzfreischaltung räumlich in dem Gehäuse, so daß alle von dem Gehäuse zu dem Antriebsgehäuse führenden Leitungen sowie alle in dem Antriebsgehäuse aufgenommenen Bauteile bei Aktivierung der Netzfreischaltung stromlos geschaltet sind.An advantageous development of the aforementioned embodiment provides that the housing in one the drive housing leading and the drive units is connected to a power supply network supply line is arranged. In this embodiment, the mains isolation takes place spatially in the housing, so that all of the housing leading to the drive housing lines and all recorded in the drive housing components are switched off when activating the mains isolation.
Eine andere vorteilhafte Weiterbildung der Erfindung sieht vor, daß das Gehäuse als Steckernetzteil ausgebildet, in ein Gehäuse eines Steckernetzteiles integriert oder in einem Gehäuse eines Steckernetzteiles aufgenommen ist. Bei dieser Ausführungsform ist das Gehäuse räumlich einem Steckernetzteil zugeordnet, so daß die Netzfreischaltung bereits in dem Steckernetzteil erfolgt. Damit erfaßt die Netzfreischaltung bereits die vollständige Zuleitung zwischen dem Steckernetzteil und dem Antriebsgehäuse.Another advantageous embodiment of the invention provides that the housing is designed as a plug-in power supply unit, integrated into a housing of a plug-in power supply unit or accommodated in a housing of a plug-in power supply unit. In this embodiment, the housing is spatially associated with a plug-in power supply, so that the mains disconnection already takes place in the plug-in power supply. Thus, the power cut already detects the complete supply line between the power supply and the drive housing.
