Abstract

The invention relates to an electromotive adjustment device for adjustable components of a slatted frame, said device being fitted with at least two drive trains having output elements which are connected to the respective component to be adjusted, either directly or using a coupling means, in such a way that the components to be adjusted can be adjusted either individually and/or together. The aim of the invention is to design one such device in such a way that the number of cost-intensive components can be reduced in order to reduce costs. According to the invention, the drive trains are driven by a drive motor downstream of which a rotational speed reducing mechanism (12, 13) provided with a worm wheel is arranged. 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

Die Erfindung betrifft eine elektromotorische Verstelleinrichtung für die verstellbaren Bauteile eines Möbels, insbesondere eines Lattenrostes, die mit mindestens zwei Antriebszügen ausgestattet ist, die mit einem einzigen Antriebsmotor antriebstechnisch verbindbar und deren Abtriebsglieder direkt oder über Koppelmittel an das jeweils zu verstellende Bauteil angeschlossen sind.The invention relates to an electromotive adjusting device for the adjustable components of a piece of furniture, in particular a slatted base, which is equipped with at least two drive trains, which are driveably connected to a single drive motor and the output members are connected directly or via coupling means to the respective component to be adjusted.

Die bislang in der Praxis eingesetzten elektromotorischen Verstelleinrichtungen der in Rede stehenden Art sind mit zwei Antriebsmotoren ausgerüstet, an denen jeweils ein Schneckentrieb angeschlossen ist. Über die Schneckentriebe werden Spindeln angetrieben, auf denen Spindelmuttern aufgesetzt 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 Verstelleinrichtungen haben sich in der Praxis bestens bewährt. Da sie jedoch als Massenprodukte 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 electromotive adjusting devices of the type in question so far used in practice are equipped with two drive motors, to each of which a worm drive is connected. Spindles are driven by the worm gears, on which spindle nuts are mounted, which are secured against rotation. These spindle nuts form the output member of each drive train, which consists of the worm gear, the spindle and the spindle nut. Usually, the head and the foot part of a slatted frame is adjusted with the so-called double drives. Such electromotive adjusting devices have proven themselves in practice. However, since they are mass-produced, they should be particularly inexpensive to produce, i. they should be structurally simple. By the two drive motors and the actuators but the cost is significantly adversely affected.

Es ist deshalb aus der US 5 829 077 bereits ein Bett bekannt, bei dem die Rückenlehne und das Fußteil von einem einzigen am Kopfende des Bettes montierten Antriebsmotor verstellbar sind. Dazu sind an den beiden Längsseiten des Bettes zwei fluchtend zueinander stehende Wellen montiert, die bereichsweise als Spindeln ausgebildet sind. Die beiden der Rückenlehne zugeordneten Wellen sind über eine weitere Welle und zwei Kegeltrieben miteinander verbunden. Diese Verbindungswelle wird von dem Antriebsmotor ebenfalls über einen Kegeltrieb angetrieben. Die beiden Wellen jeder Seite sind über Koppelelemente miteinander koppelbar, wobei diese Koppelelemente in einem Gehäuse angeordnet sind.It is therefore already known from US 5,829,077 a bed in which the backrest and the footboard of a single drive motor mounted at the head of the bed are adjustable. For this purpose, two aligned waves are mounted on the two longitudinal sides of the bed, which are partially formed as spindles. The two waves associated with the backrest are connected to each other via a further shaft and two bevel drives. This connecting shaft is also driven by the drive motor via a bevel drive. The two shafts of each side can be coupled to one another via coupling elements, wherein these coupling elements are arranged in a housing.

Diese Antriebsanordnung kommt zwar mit einem Antriebsmotor aus, ist aber konstruktiv äußerst aufwendig, da an beiden Seiten des Bettes Wellen notwendig sind, die dann auch noch über die Koppelelemente gekoppelt werden können. Ferner ist besonders nachteilig, dass das Fußteil nur verstellt werden kann, wenn die fluchtenden Wellen miteinander gekoppelt sind, woraus sich ergibt, dass auch die Rückenlehne verstellt wird. Wird aber vom Benutzer gewünscht, dass die Rückenlehne in der Stellung verbleibt, muss nach dem Verstellen des Fußteils die Rückenlehne wieder in die richtige Position gefahren werden. Diese Lösung ist daher nicht praxisgerecht.Although this drive arrangement comes with a drive motor, but is structurally extremely expensive, since waves are necessary on both sides of the bed, which can then be coupled via the coupling elements. Furthermore, it is particularly disadvantageous that the foot part can only be adjusted when the aligned shafts are coupled together, from which it follows that the backrest is adjusted. But if the user desires that the backrest remains in the position, after adjusting the foot part, the backrest must be moved back into the correct position. This solution is therefore not practical.

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 make an electromotive adjustment of the type described in more detail so that the cost reduction, the number of components, in particular the cost-intensive components can be reduced.

Die gestellte Aufgabe wird gelöst, indem dem Antriebsmotor ein Drehzahlreduziertrieb nachgeschaltet ist, der einen Rotationskörper, vorzugsweise ein Schneckenrad, aufweist, und der mit einem oder mehreren Koppelelementen derart form- und/oder kraftschlüssig verbindbar ist, dass ausschließlich ein Antriebszug in Betrieb setzbar ist.The stated object is achieved by the drive motor is followed by a speed reduction drive having a rotational body, preferably a worm wheel, and with one or more coupling elements such positive and / or non-positively connected, that only a drive train can be put into operation.

Durch die erfindungsgemäße Lösung entfällt nicht nur einer der beiden Antriebsmotore, sondern die einzige Antriebsmotor wird leistungsmäßig so ausgelegt, als wenn nur ein Möbelbauteil verstellbar wäre. Durch die Koppelung des Rotationskörpers des Drehzahlreduziertriebes wird auch nur ein einziger Schneckentrieb für die beiden Antriebszüge notwendig. Der Drehzahlreduziertrieb könnte wiederum ein Schneckentrieb sein, so dass bei der erfindungsgemäßen Lösung 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.The inventive solution eliminates not only one of the two drive motors, but the only drive motor is designed in terms of performance as if only a furniture component would be adjustable. Due to the coupling of the rotational body of the speed reduction drive only a single worm drive for the two drive trains is necessary. The speed-reducing drive could again be a worm drive, so that in the solution according to the invention a worm drive is also saved. This coupling element could be switchable by means of an electrical switching element, preferably an electromagnet or a lifting magnet. The coupling element comes depending on the switching position with the rotating body in contact. In a preferred embodiment, the coupling element on a the output member, preferably the spindle nut moving and rotatably driven spindle rotatably mounted. In the embodiment according to the invention therefore two coupling elements are used. These are formed in a preferred embodiment as in the axial direction, relative to the longitudinal axis of the spindles, movable drawing clutches. For an electromagnetic circuit to be possible, it should be made of a magnetizable material, for example of metal, a sintered material or by casting.

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 Spindelmutter 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 Ausführungsbeispielen ein Schneckenrad 12 lose verdrehbar 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 Koppelelemente 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, 1 verfahren werden, nehmen jedoch bei der Drehbewegung 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 adjusting device includes two spindles 10, 11, which are each part of a drive train. In a manner not shown, a spindle secured against rotation spindle nut is mounted on each spindle 10, 11, the process in rotation of the spindles 10, 11 in the longitudinal direction of the spindles 10, 11. These spindle nuts can press on an articulation lever to adjust, for example, the head or the foot of a slatted frame. However, they can also be coupled in another way with the components to be adjusted. On the mutually facing ends of the spindles 10, 11 a worm wheel 12 is loosely mounted rotatably in the illustrated embodiments. This worm wheel 12 is driven by a worm 13 which is mounted on the output pin 14 of an otherwise not shown drive motor rotatably. In contrast to the illustrated embodiment, the output pin of the drive motor could be designed as a worm. Laterally adjacent to the worm wheel 12, two coupling elements 14, 15 are mounted on bushings 16, 17, wherein the bushes 16, 17 rotatably connected to the spindles 10, 11 are connected. The coupling elements 14, 15 can be moved in the longitudinal direction of the spindles 10, 1, however, take with the rotational movement of the worm wheel 12, the spindles 10, 11, provided they are in the operating position. The coupling elements 14, 15 and the drawing clutches are moved by magnets 18, 19 in the longitudinal directions of the spindles 10, 11.

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 of Figure 1, the worm wheel 12 is positively connected to the coupling elements 14, 15. On the mutually facing sides, the coupling elements 14, 15 are provided with projecting pins 20, 21, which engage in corresponding bores of the worm wheel. In a corresponding circuit of the magnets 18, 19, the pins 20, 21 come either in engagement or out of engagement with the worm wheel 12. In the embodiment of Figure 2, the magnets 18, 19 are provided with two pins in the circumferential grooves of the coupling elements fourteenth , 15 intervene. These coupling elements are annular and can also be connected via the magnets 18, 19 such that entrainment takes place by the worm wheel 12 or that they stand still 12 despite rotation of the worm wheel.

In einer im einzelnen nicht dargestellten, weiteren Ausfiihrungsform 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 drive of the spindles 10, 11 could take place via two mutually opposite bevel gears. Right angle to the axes of rotation of the bevel gears or to the longitudinal axes of the spindles 10, 11 is then another bevel gear, which could also be switched via a magnet or a similar component and only with a bevel gear in Intervention is. To reduce this central bevel gear could be connected to the worm wheel and therefore 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 limited to the illustrated and described embodiments. It is essential that the adjusting device has at least two drive trains, which can be driven by a common motor, wherein either either only one drive train can be put into operation, or with a corresponding design of the drive motor on both drive trains.
