The drive motor is connected to at least one coupling element (14, 15) in a positively locking and/or force locking manner. Said coupling elements (14, 15) can be switched by electromagnets (18, 19). The inventive electromotive adjustment device is especially suitable for a slatted frame.

Description

Elektromotorische Verstelleinrichtung Electromotive adjustment device
Die Erfindung betrifft eine elektromotorische Verstelleinrichtung für die verstellbaren Bauteile eines Möbels, insbesondere eines Lattenrostes, die mit mindestens zwei Antriebszügen ausgestattet ist, deren Abtriebsglieder direkt oder über Koppelelemente an das jeweils zu verstellende Bauteil derart angeschlossen sind, daß die zu verstellenden Bauteile wahlweise einzeln und/oder gemeinsam verstellbar sind. Die bislang bekannten elektromotorischen Nerstelleinrichtungen der in Rede stehenden Art sind mit zwei Antriebsmotoren ausgerüstet, an denen jeweils ein Schneckentrieb angeordnet ist. Ü- ber die Schneckentriebe werden Spindeln angetrieben, auf denen Spindelmuttern auf- gesetzt sind, die gegen Drehung gesichert sind. Diese Spindelmuttern bilden das Abtriebsglied jedes Antriebszuges, welcher aus dem Schneckentrieb, der Spindel und der Spindelmutter besteht. Üblicherweise wird mit den sog. Doppelantrieben das Kopf- und das Fußteil eines Lattenrostes verstellt. Derartige elektromotorische Nerstelleinrichtungen haben sich in der Praxis bestens bewährt. Da sie jedoch als Massenproduk- te anzusehen sind, sollten sie besonders kostengünstig herstellbar sein, d.h. sie sollten konstruktiv einfach aufgebaut sein. Durch die beiden Antriebsmotoren und die Stelltriebe werden jedoch die Kosten deutlich ungünstig beeinflußt.The invention relates to an electromotive adjustment device for the adjustable components of a piece of furniture, in particular a slatted frame, which is equipped with at least two drive trains, the output members of which are connected directly or via coupling elements to the component to be adjusted in such a way that the components to be adjusted are optionally individually and / or are adjustable together. The previously known electromotive ner adjusting devices of the type in question are equipped with two drive motors, on each of which a worm drive is arranged. Spindles are driven via the worm drives, on which spindle nuts are placed, which are secured against rotation. These spindle nuts form the output member of each drive train, which consists of the worm drive, the spindle and the spindle nut. The head and foot sections of a slatted frame are usually adjusted using the so-called double drives. Such electromotive ner adjusting devices have proven their worth in practice. However, since they are to be regarded as mass products, they should be able to be manufactured particularly cost-effectively, i.e. they should be structurally simple. However, the costs are influenced significantly by the two drive motors and the actuators.
Der Erfindung liegt die Aufgabe zugrunde, eine elektromotorische Verstelleinrichtung der eingangs näher beschriebenen Art so zu gestalten, daß zur Kostenreduzierung die Anzahl der Bauteile, insbesondere der kostenintensiven Bauteile verringert werden kann.The invention has for its object to design an electromotive adjusting device of the type described in the introduction in such a way that the number of components, in particular the cost-intensive components, can be reduced in order to reduce costs.
Die gestellte Aufgabe wird gelöst, indem die Antriebszüge mit einem einzigen An- triebsmotor antriebstechnisch verbunden sind.The task is solved by connecting the drive trains with a single drive motor.
Durch die erfindungsgemäße Lösung entfällt zumindest einer der beiden Antriebsmo- tore. Selbst wenn man davon ausgeht, daß die Leistung des einzigen Antriebsmotors nunmehr im Bedarfsfalle erhöht werden muß, ist jedoch ein Motor bei einem geringe- ren Preis zu beziehen als zwei Motore. Außerdem entfallen noch die elektrischen bzw. elektronischen Bauteile zum Ansteuern des zweiten Motors. In weiterer Ausgestaltung ist vorgesehen, daß dem Antriebsmotor ein Drehzahlreduziertrieb nachgeschaltet ist, daß dieser einen Rotationskörper aufweist, der mit einem oder mit mehreren Koppelelementen form- und/oder kraftschlüssig koppelbar ist. Bei dieser Ausführung könnte der Drehzahlreduziertrieb wiederum ein Schneckentrieb sein, so daß bei der erfindungsgemäßen Lösung nicht nur ein Motor sondern auch ein Schneckentrieb eingespart wird. Dieses Koppelelement könnte mittels eines elektrischen Schaltelementes, vorzugsweise eines Elektromagneten bzw. eines Hubmagneten schaltbar sein. Das Koppelelement kommt je nach der Schaltstellung mit dem Rotationskörper in Kontakt. In bevorzugter Ausführungsform ist das Koppelelement auf eine das Abtriebsglied, vorzugsweise die Spindelmutter bewegende und rotierend antreibbare Spindel drehfest aufgesetzt. Bei der erfindungsgemäßen Ausführung werden demzufolge zwei Koppelelemente verwendet. Diese sind in bevorzugter Ausführung als in axialer Richtung, bezogen auf die Längsachse der Spindeln, verfahrbare Ziehkupplungen ausgebildet. Damit eine elektromagnetische Schaltung möglich ist, sollte sie aus einem magnetisierbaren Material, beispielsweise aus Metall, einem Sintermaterial oder im Gießverfahren hergestellt sein. Zur weiteren Kostenreduzierung ist vorgesehen, daß bei der elektromotorischen Nerstelleinrichtung nur Antriebszug in Betrieb gesetzt werden kann, da dadurch die Leistung des Motors nur für einen Antriebszug ausgelegt sein muß.The solution according to the invention eliminates at least one of the two drive motors. Even if one assumes that the power of the single drive motor must now be increased if necessary, one motor can be purchased at a lower price than two motors. In addition, there are no electrical or electronic components for controlling the second motor. In a further embodiment it is provided that a speed reduction drive is connected downstream of the drive motor, that it has a rotating body which can be positively and / or non-positively coupled to one or more coupling elements. In this embodiment, the speed reduction drive could in turn be a worm drive, so that in the solution according to the invention not only a motor but also a worm drive is saved. This coupling element could be switchable by means of an electrical switching element, preferably an electromagnet or a lifting magnet. The Depending on the switching position, the coupling element comes into contact with the rotating body. In a preferred embodiment, the coupling element is non-rotatably mounted on a spindle that moves and rotates the output member, preferably the spindle nut. Accordingly, two coupling elements are used in the embodiment according to the invention. In a preferred embodiment, these are designed as pulling couplings which can be moved in the axial direction with respect to the longitudinal axis of the spindles. In order for an electromagnetic circuit to be possible, it should be made of a magnetizable material, for example metal, a sintered material or using the casting process. To further reduce costs, it is provided that only the drive train can be put into operation in the electromotive ner setting device, since as a result the power of the motor only has to be designed for one drive train.
Anhand der beiliegenden Zeichnungen wird die Erfindung noch näher erläutert. Es zeigen:The invention is explained in more detail with reference to the accompanying drawings. Show it:
Figur 1 die elektromotorische Verstelleinrichtung in einer Teilansicht, in einer ersten Ausführungsform und Figur 2 die elektromotorische Verstelleinrichtung in einer Teilansicht, in einer zweiten Ausfuhrungsform.Figure 1 shows the electromotive adjustment device in a partial view, in a first embodiment and Figure 2 shows the electromotive adjustment device in a partial view, in a second embodiment.
Im dargestellten Ausführungsbeispiel enthält die elektromotorische Verstelleinrichtung zwei Spindeln 10, 11, die jeweils Teil eines Antriebszuges sind. In nicht dargestellter Weise wird auf jede Spindel 10, 11 eine gegen Drehung gesicherte Spindel- mutter aufgesetzt, die bei Drehung der Spindeln 10, 11 in Längsrichtung der Spindeln 10, 11 verfahren. Diese Spindelmuttern können auf einen Anlenkhebel drücken, um beispielsweise das Kopf- bzw. das Fußteil eines Lattenrostes zu verstellen. Sie können jedoch auch in anderer Weise mit den zu verstellenden Bauteilen gekoppelt sein. Auf die einander zugewandten Enden der Spindeln 10, 11 ist in den dargestellten Ausfüh- rungsbeispielen ein Schneckenrad 12 drehfest aufgesetzt. Dieses Schneckenrad 12 wird von einer Schnecke 13 angetrieben, die auf den Abtriebszapfen 14 eines ansonsten nicht dargestellten Antriebsmotors drehfest aufgesetzt ist. Im Gegensatz zu der dargestellten Ausführung könnte auch der Abtriebszapfen des Antriebsmotors als Schnecke ausgebildet sein. Seitlich neben dem Schneckenrad 12 sind zwei Koppel- elemente 14, 15 auf Buchsen 16, 17 aufgesetzt, wobei die Buchsen 16, 17 drehfest mit den Spindeln 10, 11 verbunden sind. Die Koppelelemente 14, 15 können in Längsrichtung der Spindeln 10, 11 verfahren werden, nehmen jedoch bei der Drehbewegung des Schneckenrades 12 die Spindeln 10, 11 mit, sofern sie in der des Schneckenrades 12 die Spindeln 10, 11 mit, sofern sie in der Betriebsstellung stehen. Die Koppelelemente 14, 15 bzw. die Ziehkupplungen werden über Magnete 18, 19 in den Längsrichtungen der Spindeln 10, 11 verfahren.In the illustrated embodiment, the electromotive adjustment device contains two spindles 10, 11, which are each part of a drive train. In a manner not shown, a spindle nut secured against rotation is placed on each spindle 10, 11 and moves in the longitudinal direction of the spindles 10, 11 when the spindles 10, 11 rotate. These spindle nuts can press on a link lever, for example to adjust the head or foot section of a slatted frame. However, they can also be coupled to the components to be adjusted in a different way. In the illustrated exemplary embodiments, a worm wheel 12 is placed on the mutually facing ends of the spindles 10, 11 in a rotationally fixed manner. This worm wheel 12 is driven by a worm 13 which is non-rotatably mounted on the driven pin 14 of an otherwise not shown drive motor. In contrast to the embodiment shown, the output pin of the drive motor could also be designed as a worm. To the side of the worm wheel 12, two coupling elements 14, 15 are placed on bushings 16, 17, the bushes 16, 17 being connected to the spindles 10, 11 in a rotationally fixed manner. The coupling elements 14, 15 can be moved in the longitudinal direction of the spindles 10, 11, but take the spindles 10, 11 with them when the worm wheel 12 rotates, provided that they are in the of the worm wheel 12 with the spindles 10, 11, provided that they are in the operating position. The coupling elements 14, 15 or the pulling couplings are moved in the longitudinal directions of the spindles 10, 11 via magnets 18, 19.
Bei der Ausführung nach der Figur 1 ist das Schneckenrad 12 mit den Koppelelementen 14, 15 formschlüssig verbunden. An den einander zugewandten Seiten sind die Koppelelemente 14, 15 mit vorstehenden Stiften 20, 21 versehen, die in entsprechende Bohrungen des Schneckenrades eingreifen. Bei einer entsprechenden Schaltung der Magnete 18, 19 kommen die Stifte 20, 21 entweder in Eingriff oder außer Eingriff mit dem Schneckenrad 12. Bei der Ausführung nach der Figur 2 sind die Magnete 18, 19 mit zwei Stiften versehen, die in Umfangsnuten der Koppelelemente 14, 15 eingreifen. Diese Koppelelemente sind ringförmig ausgebildet und können ebenfalls über die Magnete 18, 19 derart geschaltet werden, daß eine Mitnahme durch das Schneckenrad 12 erfolgt oder daß sie trotz Drehung des Schneckenrades 12 stillstehen.In the embodiment according to FIG. 1, the worm wheel 12 is positively connected to the coupling elements 14, 15. On the sides facing one another, the coupling elements 14, 15 are provided with projecting pins 20, 21 which engage in corresponding bores in the worm wheel. When the magnets 18, 19 are switched accordingly, the pins 20, 21 either engage or disengage from the worm wheel 12. In the embodiment according to FIG. 2, the magnets 18, 19 are provided with two pins, which are located in circumferential grooves of the coupling elements 14 , 15 intervene. These coupling elements are ring-shaped and can also be switched via the magnets 18, 19 in such a way that entrainment takes place by the worm wheel 12 or that they stand still despite the worm wheel 12 rotating.
In einer im einzelnen nicht dargestellten, weiteren Ausführungsform könnte der Antrieb der Spindeln 10, 11 über zwei einander gegenüberliegende Kegelräder erfolgen. Rechtwinklig zu den Drehachsen der Kegelräder bzw. zu den Längsachsen der Spindeln 10, 11 steht dann ein weiteres Kegelrad, welches ebenfalls über einen Magneten oder ein ähnliches Bauteil geschaltet werden könnte und nur mit einem Kegelrad in Eingriff steht. Zur Reduzierung könnte dieses mittlere Kegelrad mit dem Schneckenrad verbunden sein und demzufolge synchron mitlaufen.In a further embodiment, not shown in detail, the spindles 10, 11 could be driven via two bevel gears located opposite one another. At right angles to the axes of rotation of the bevel gears or to the longitudinal axes of the spindles 10, 11 is another bevel gear, which could also be switched via a magnet or a similar component and is only in engagement with a bevel gear. To reduce this middle bevel gear could be connected to the worm gear and consequently run synchronously.
Die Erfindung ist nicht auf die dargestellten und beschriebenen Ausführungsbeispiele beschränkt. Wesentlich ist, daß die Verstelleinrichtung mindestens zwei Antriebszüge aufweist, die von einem gemeinsamen Motor antreibbar sind, wobei wahlweise entweder nur ein Antriebszug in Betrieb gesetzt werden kann, oder bei einer entsprechenden Auslegung des Antriebsmotors auf beide Antriebszüge. The invention is not restricted to the exemplary embodiments shown and described. It is essential that the adjustment device has at least two drive trains which can be driven by a common motor, either either only one drive train being put into operation, or with a corresponding design of the drive motor for both drive trains.
