Description

Die Erfindung betrifft einen elektromotorischen Möbelantrieb der im Oberbegriff des Anspruchs 1 genannten Art zum Verstellen von Teilen eines Möbels relativ zueinander.The invention relates to an electromotive furniture drive referred to in the preamble of claim 1 for adjusting parts of a piece of furniture relative to each other.

Derartige Möbelantriebe sind allgemein bekannt und dienen beispielsweise zum Verstellen von verstellbaren Teilen eines Lattenrostes.Such furniture drives are well known and are used for example for adjusting adjustable parts of a slatted frame.

Die bekannten Möbelantriebe weisen eine Handbedieneinrichtung, beispielsweise in Form eines sogenannten Handschalters, mit einem Bedienelement oder mehreren Bedienelementen auf, mittels dessen bzw. derer die verschiedenen Funktionen des Möbelantriebs, beispielsweise das Anheben und Absenken eines Kopf- bzw. eines Fußteiles des Lattenrostes auslösbar sind.The known furniture drives have a manual control device, for example in the form of a so-called hand switch, with one or more controls by means of which or the various functions of the furniture drive, such as lifting and lowering a head or a foot part of the slatted frame are triggered.

Der Erfindung liegt die Aufgabe zugrunde, einen Möbelantrieb der betreffenden Art anzugeben, bei dem die Bedienung besonders einfach gestaltet ist und der einfach und kostengünstig herstellbar ist.The invention has for its object to provide a furniture drive of the type in question, in which the operation is designed particularly simple and is easy and inexpensive to produce.

Diese Aufgabe wird durch die im Anspruch 1 angegebene Lehre gelöst.This object is achieved by the teaching defined in claim 1.

Die erfindungsgemäße Lehre sieht vor, daß das Bedienelement von Hand in wenigstens zwei Rastpositionen bewegbar ist, wobei jeder Rastposition ein vorgegebener Verstellhub eines zu verstellenden Teiles des Möbels zugeordnet ist. Im einfachsten Fall kann die Handbedieneinrichtung des erfindungsgemäßen Möbelantriebs beispielsweise so gestaltet sein, daß ihr Bedienelement aus einer Ruheposition in zwei Rastpositionen bewegbar ist, wobei der ersten Rastposition beispielsweise eine Verstellung eines Kopfteiles eines Lattenrostes in eine halb angehobene Verstellage und der zweiten Rastposition beispielsweise eine Verstellung des Kopfteiles in eine vollständig angehobene Verstellage zugeordnet sein kann. Da erfindungsgemäß die Rastpositionen den einzelnen Verstellagen eindeutig zugeordnet sind, ist es für einen Benutzer des Möbelantriebs ausreichend, sich zu merken, in welcher Rastposition, also nach wie vielen Rastungen, eine gewünschte Verstellage erreicht ist. Dies ist auch bei einer Vielzahl von Rastpositionen ohne weiteres möglich, indem der Benutzer beispielsweise ein Kopfteil eines Lattenrostes in eine von ihm bevorzugte Verstelllage bewegt und abzählt, wie viele Rastungen erforderlich sind, um diese Verstellage zu erreichen. Um das Kopfteil des Lattenrostes aus einer Ausgangslage in die bevorzugte Verstellage zu bewegen, ist es lediglich erforderlich, das Bedienelement so zu betätigen, daß die zuvor gemerkte Anzahl von Rastungen erreicht ist. Da jeder Rastposition eindeutig eine Verstellage zugeordnet ist, wird das Kopfteil des Lattenrostes mittels des Möbelantriebs in die der gewählten Rastposition zugeordnete Verstellage bewegt, die der von dem Benutzer bevorzugten Verstellage entspricht. Auf diese Weise ergibt sich eine besonders einfache und intuitive Bedienung des erfindungsgemäßen Möbelantriebs.The teaching of the invention provides that the operating element is manually movable in at least two locking positions, wherein each locking position is assigned a predetermined Verstellhub a part to be adjusted of the furniture. In the simplest case, the manual control device For example, an adjustment of a head part of a slatted frame in a half raised Verstellage and the second locking position, for example, an adjustment of the head part in a fully raised Verstellage can be assigned. Since, according to the invention, the detent positions are unambiguously associated with the individual adjustment positions, it is sufficient for a user of the furniture drive to remember in which detent position, ie after how many detents, a desired adjustment position has been reached. This is readily possible even with a plurality of detent positions, for example, by the user moves a head part of a slatted frame in a preferred adjustment of him and counting how many notches are required to reach this Verstellage. In order to move the head part of the slatted frame from a starting position in the preferred adjustment, it is only necessary to operate the control element so that the previously noted number of notches is reached. Since each detent position is uniquely associated with an adjustment, the head part of the slatted base is moved by means of the furniture drive in the selected detent position associated Verstellage, which corresponds to the preferred adjustment by the user. In this way, a particularly simple and intuitive operation of the furniture drive according to the invention.

Ein besonderer Vorteil des erfindungsgemäßen Möbelantriebs besteht darin, daß grundsätzlich auf sogenannte Memory-Schaltungen verzichtet werden kann, die bei bekannten Möbelantrieben vorgesehen sind, um das zu verstellende Teil des Möbels in eine zuvor abgespeicherte Verstellage zu bewegen. Bei dem erfindungsgemäßen Möbelantrieb merkt sich der Benutzer lediglich, in welcher Rastposition, also nach welcher Anzahl von Rastungen, die von ihm gewünschte Verstellage erreicht ist.A particular advantage of the furniture drive according to the invention is that in principle can be dispensed with so-called memory circuits, which are provided in known furniture drives to the moving part of the furniture in a previously stored Verstellage. In the furniture drive according to the invention, the user merely notices in which latching position, that is to say after which number of notches, the adjustment position desired by him is reached.

Unter einer Rastung wird erfindungsgemäß ein Vorgang verstanden, bei dem sich das Bedienelement in eine Rastposition bewegt.A detent is understood according to the invention to mean a process in which the operating element moves into a detent position.

Erfindungsgemäß ist es ausreichend, wenn die Handbedieneinrichtung des erfindungsgemäßen Möbelantriebs lediglich ein Bedienelement aufweist. Es können jedoch auch zwei oder mehrere Bedienelemente vorgesehen sein. Beispielsweise und insbesondere können zwei Bedienelemente vorgesehen sein, wobei durch das eine eine Verstellung beispielsweise eines Kopfteiles eines Lattenrostes und durch das andere beispielsweise eine Verstellung eines Fußteiles eines Lattenrostes auslösbar sein kann.According to the invention, it is sufficient if the manual operating device of the furniture drive according to the invention has only one operating element. However, it can also be provided two or more controls. For example, and in particular two controls can be provided, which can be triggered by the one adjustment of, for example, a head part of a slatted frame and by the other, for example, an adjustment of a foot part of a slatted frame.

Unter einer Rastposition wird erfindungsgemäß eine Position des Bedienelementes verstanden, deren Erreichen von einem Benutzer des Möbelantriebs auf akustische und/oder taktile Weise wahrnehmbar ist. Dementsprechend kann das Erreichen der Rastpositionen beispielsweise auf ausschließlich akustische Weise angezeigt werden, indem beim Erreichen einer Rastposition des Bedienelementes ein akustisches Signal erzeugt wird. Eine besonderes vorteilhafte Weiterbildung der erfindungsgemäßen Lehre sieht vor, daß dem Bedienelement mechanische Rastmittel zugeordnet sind. Bei dieser Ausführungsform findet beim Erreichen einer Rastposition ein mechanischer Rastvorgang statt, der von einem Benutzer des Möbelantriebs sowohl akustisch über ein Rastgeräusch als auch taktil wahrgenommen werden kann. Auf diese Weise ist das Erreichen der Rastpositionen für den Benutzer besonders einfach wahrnehmbar.A detent position is understood according to the invention to mean a position of the operating element whose reaching is perceptible by a user of the furniture drive in an acoustic and / or tactile manner. Accordingly, the achievement of the detent positions can be displayed, for example, in an exclusively acoustic manner by generating an acoustic signal when a detent position of the operating element is reached. A particularly advantageous development of the teaching of the invention provides that the control element mechanical latching means are assigned. In this embodiment, upon reaching a detent position, a mechanical latching action takes place, which can be perceived by a user of the furniture drive both acoustically via a detent sound as well as tactile. In this way, the achievement of the locking positions for the user is particularly easy to perceive.

Grundsätzlich kann es sich bei dem Bedienelement der Handbedieneinrichtung beispielsweise um einen Schiebeschalter handeln, der entlang seines Verschiebeweges unterschiedliche Rastpositionen einnimmt. Eine vorteilhafte Weiterbildung der erfindungsgemäßen Lehre sieht jedoch vor, daß das Bedienelement als drehbar gelagertes Bedienrad ausgebildet ist und daß die Rastpositionen unterschiedlichen Drehlagen des Bedienrades entsprechen. Bei dieser Ausführungsform ist die Bedienung des erfindungsgemäßen Möbelantriebs noch einfacher und intuitiver gestaltet, indem ein Benutzer des Möbelantriebs durch Drehung des Bedienrades unterschiedliche Verstellagen eines zu verstellenden Teils des Möbels auswählen kann.In principle, the operating element of the manual operating device may, for example, be a slide switch which assumes different latching positions along its displacement path. An advantageous development of the teaching of the invention, however, provides that the operating element is designed as a rotatably mounted operating wheel and that the locking positions correspond to different rotational positions of the operating wheel. In this embodiment, the operation of the furniture drive according to the invention is even simpler and more intuitive designed by a user of the furniture drive can select different Verstellagen a part to be adjusted by turning the control wheel.

Um bei der Ausführungsform mit dem Bedienrad die Rastmittel besonders einfach und damit kostengünstig zu gestalten, sieht eine vorteilhafte Weiterbildung der erfindungsgemäßen Lehre insoweit vor, daß die Rastmittel wenigstens ein drehfest mit dem Bedienrad verbundenes Zahnrad aufweisen, an dessen Umfang wenigstens ein Rastelement, insbesondere wenigstens eine Rastfeder anliegt.In order to make the locking means in the embodiment with the operating wheel particularly simple and therefore cost, provides an advantageous development of the teaching according to the extent that the locking means have at least one non-rotatably connected to the operating gear, on whose circumference at least one locking element, in particular at least one Resting spring.

Um den Möbelantrieb entsprechend der von dem Benutzer gewählten Rastposition anzusteuern, sind Erfassungsmittel zur Erfassung der Drehlage des Bedienrades erforderlich. Eine vorteilhafte Weiterbildung der erfindungsgemäßen Lehre sieht insoweit elektrische oder elektronische Erfassungsmittel zur Erfassung der Drehlage des Bedienrades vor.In order to control the furniture drive in accordance with the selected by the user locking position, detection means for detecting the rotational position of the operating wheel are required. An advantageous development of the teaching of the invention provides insofar as electrical or electronic detection means for detecting the rotational position of the operating wheel.

Um bei der vorgenannten Ausführungsform die Erfassungsmittel besonders einfach und damit kostengünstig zu gestalten, sieht eine vorteilhafte Weiterbildung dieser Ausführungsform vor, daß die Erfassungsmittel wenigstens ein Potentiometer aufweisen. Entsprechende Potentiometer stehen als relativ einfache und kostengünstige Standardbauteile zur Verfügung.In order to make the detection means particularly simple and thus cost-effective in the aforementioned embodiment, provides an advantageous development of this embodiment, that the detection means comprise at least one potentiometer. Corresponding potentiometers are available as relatively simple and inexpensive standard components.

Entsprechend den jeweiligen Anforderungen können zur Erfassung der Drehlage des Bedienrades jedoch auch optische oder optoelektronische Erfassungsmittel vorsehen, wie dies eine andere Weiterbildung der erfindungsgemäßen Lehre angibt. Beispielsweise und insbesondere kann mit einer Welle des Bedienrades drehfest eine Lochscheibe verbunden sein, die im Strahlengang einer Lichtschranke angeordnet ist, so daß entsprechend der Drehlage des Bedienrades die Lichtschranke entweder unterbrochen oder geschlossen ist und auf diese Weise eine Drehung des Bedienrades festgestellt werden kann.However, according to the respective requirements, optical or opto-electronic detection means can also provide for detecting the rotational position of the operating wheel, as indicated by another development of the teaching according to the invention. For example, and in particular may rotatably connected to a shaft of the operating wheel a perforated disc, which is arranged in the beam path of a light barrier, so that according to the rotational position of the operating wheel, the light barrier is either interrupted or closed and in this way a rotation of the operating wheel can be determined.

Um mittels der erfindungsgemäßen Handbedieneinrichtung zusätzliche Funktionen des Möbelantriebs auszulösen, sieht eine andere Weiterbildung der erfindungsgemäßen Lehre vor, daß das Bedienrad in Radialrichtung seiner Drehachse entlang einer linearen Betätigungsachse beweglich gelagert ist und daß der linearen Betätigungsachse ein Schalter zugeordnet ist. Bei dieser Ausführungsform kann der Schalter beispielsweise dadurch betätigt werden, daß der Benutzer auf das Bedienrad drückt. Erfindungsgemäß können dem Schalter beliebige geeignete Funktionen des Möbelantriebs zugeordnet sein.In order to trigger additional functions of the furniture drive by means of the hand control device according to the invention, another embodiment of the teaching according to the invention provides that the operating wheel is mounted movably in the radial direction of its axis of rotation along a linear actuating axis and that the switch is associated with the linear actuating axis. In this embodiment, the switch may be operated, for example, by the user pressing on the operating wheel. According to the invention, any suitable functions of the furniture drive can be assigned to the switch.

Falls bei dem erfindungsgemäßen Möbelantrieb eine sogenannte "Reset"-Funktion realisiert werden soll, so sieht eine vorteilhafte Weiterbildung der vorgenannten Ausführungsform vor, daß durch den Schalter eine Rückstellung des zu verstellenden Teils des Möbels in eine vorgegebene Ausgangslage auslösbar ist. Bei dieser Ausführungsform wird die Verstellung eines zu verstellenden Teiles des Möbels dadurch ausgelöst, daß der Benutzer das Bedienrad dreht, während durch Bewegung des Bedienrades entlang der linearen Betätigungsachse der Möbelantrieb so angesteuert wird, daß er das zu verstellende Teil des Möbels in eine vorgegebene Ausgangslage bewegt, so daß auf diese Weise eine "Reset"-Funktion realisiert ist.If a so-called "reset" function is to be realized in the furniture drive according to the invention, so provides an advantageous development of the aforementioned embodiment that a reset of the part to be adjusted of the furniture in a predetermined starting position can be triggered by the switch. In this embodiment, the adjustment of one to be adjusted Part of the furniture triggered by the fact that the user turns the wheel, while being driven by movement of the control wheel along the linear actuation axis of the furniture drive so that it moves the part to be adjusted of the furniture in a predetermined starting position, so that in this way a "Reset "Function is realized.

Bei einer Drehung des Bedienrades 10 um seine Drehachse rasten die Rastfedern 18, 20 für einen Benutzer der Handbedieneinrichtung 2 deutlich hör- sowie an dem Bedienrad fühlbar zwischen den Zähnen des Zahnrades 16 ein, so daß auf diese Weise die Rastpositionen des Bedienrades 10 definiert sind.In the illustrated embodiment, the operating wheel 10 is associated with mechanical locking means which in this embodiment have a non-rotatably connected to the operating wheel 10 gear 16, abut on the circumference of two locking elements in the form of locking springs 18, 20. Upon rotation of the control wheel 10 about its axis of rotation, the detent springs 18, 20 for a user the manual control device 2 clearly audible and on the operating wheel between the teeth of the gear 16 a, so that in this way the locking positions of the control wheel 10 are defined.

Zur Erfassung der Drehlage des Bedienrades 10 sind bei diesem Ausführungsbeispiel elektrische Erfassungsmittel in Form eines Potentiometers vorgesehen, das mit dem dem Zahnrad 16 zugewandten Ende der Drehachse des Bedienrades 10 zusammenwirkt. Das Gehäuse des Potentiometers ist in Fig. 2 mit dem Bezugszeichen 21 bezeichnet. In dem Fachmann allgemein bekannter Weise setzt das Potentiometer unterschiedliche Drehlagen des Bedienrades 10 in unterschiedliche Widerstände um, so daß anhand des jeweiligen Widerstandes festgestellt werden kann, in welcher Drehlage sich das Bedienrad 10 jeweils befindet.For detecting the rotational position of the operating wheel 10, electrical detection means in the form of a potentiometer are provided in this embodiment, which cooperates with the gear 16 facing the end of the axis of rotation of the control wheel 10. The housing of the potentiometer is in Fig. 2 designated by the reference numeral 21. In a manner well-known to those skilled in the art, the potentiometer converts different rotational positions of the operating wheel 10 into different resistances, so that it can be determined from the respective resistance in which rotational position the operating wheel 10 is located.

Bei dem in der Zeichnung dargestellten Ausführungsbeispiel ist das Bedienrad in Radialrichtung seiner Drehachse entlang einer linearen Betätigungsachse, die in Fig. 2 durch einen Pfeil 22 symbolisiert ist, beweglich gelagert, wobei der linearen Betätigungsachse ein Schalter zugeordnet ist, auf dem das dem Zahnrad 16 abgewandte Ende der Drehachse des Bedienrades 10 federnd aufliegt, so daß der Schalter betätigt wird, wenn das Bedienrad 10 in Fig. 2 nach unten entlang der Betätigungsachse 22 gedrückt wird. Bei dem dargestellten Ausführungsbeispiel ist durch den Schalter eine Rückstellung des zu verstellenden Teils des Möbels in eine vorgegebene Ausgangslage auslösbar.In the embodiment shown in the drawing, the operating wheel is in the radial direction of its axis of rotation along a linear actuating axis, which in Fig. 2 symbolized by an arrow 22, movably mounted, wherein the linear actuating axis is associated with a switch on which the gear 16 remote from the end of the axis of rotation of the operating wheel 10 resiliently rests, so that the switch is actuated when the operating wheel 10 in Fig. 2 is pressed down along the actuating axis 22. In the illustrated embodiment, a provision of the part to be adjusted of the furniture in a predetermined starting position can be triggered by the switch.

Die Funktionsweise des erfindungsgemäßen Möbelantriebs ist wie folgt:The operation of the furniture drive according to the invention is as follows:

Um beispielsweise ein Kopfteil eines Lattenrostes mittels des Möbelantriebs zu verstellen, dreht ein Benutzer des Möbelantriebs ausgehend von einer Ausgangslage, in der das Kopfteil des Lattenrostes beispielsweise horizontal angeordnet ist, das Bedienrad 10. Dreht der Benutzer das Bedienrad 10 hierbei um 360°, so wird eine Antriebseinheit des Möbelantriebs so angesteuert, daß sie das Kopfteil des Lattenrostes aus der Ausgangslage in eine Endlage der Verstellbewegung bewegt, in der das Kopfteil beispielsweise unter einem Winkel von 45° geneigt angeordnet ist. Möchte der Benutzer das Kopfteil in eine Verstellage zwischen der Ausgangslage und der Endlage bewegen, so dreht er das Bedienrad 10 um einen entsprechend geringeren Umfangswinkel, wobei das Bedienrad 10 während seiner Drehung aufeinanderfolgend in unterschiedliche Rastpositionen gelangt. Das Erreichen einer Rastposition, in der die Rastfedern 18, 20 jeweils zwischen zwei Zähnen des Zahnrades 16 einrasten, ist für einen Benutzer des Möbelantriebs deutlich hör- und darüber hinaus an dem Bedienrad 10 fühlbar. Entspricht eine Drehung des Bedienrades 10 um einen Umfangswinkel von 360° beispielsweise zwölf Rastungen und einer Verstellung des Kopfteiles in eine Endlage der Verstellbewegung, so entspricht eine Drehung des Bedienrades 10 um 180° beispielsweise sechs Rastungen und einer Verstellung des Kopfteiles in eine Verstellage zwischen der Ausgangslage und der Endlage.For example, in order to adjust a head part of a slatted base by means of the furniture drive, a user of the furniture drive rotates starting from a starting position, If the user rotates the operating wheel 10 by 360 °, then a drive unit of the furniture drive is controlled so that it moves the head part of the slatted base from the starting position into an end position of the adjusting movement in which the head part is arranged, for example inclined at an angle of 45 °. If the user wishes to move the head part into an adjustment position between the initial position and the end position, then he turns the operating wheel 10 by a correspondingly smaller circumferential angle, wherein the operating wheel 10 successively reaches different locking positions during its rotation. The achievement of a detent position in which the detent springs 18, 20 each engage between two teeth of the gear 16 is clearly audible for a user of the furniture drive and beyond felt on the control wheel 10. Corresponds to a rotation of the control wheel 10 by a circumferential angle of 360 °, for example, twelve detents and an adjustment of the head part in an end position of the adjustment, so corresponds to a rotation of the control wheel 10 by 180 °, for example, six detents and an adjustment of the head part in an adjustment position between the starting position and the final position.

Bei der Verstellung des Kopfteiles kann der Benutzer zunächst durch Drehen an dem Bedienrad 10 seine bevorzugte Verstellage des Kopfteiles anwählen und währen der Drehung des Bedienrades 10 mitzählen, wie viele Rastungen erforderlich sind, um in die gewünschte Verstellage zu gelangen.When adjusting the head part, the user can first select by turning the wheel 10 its preferred adjustment of the head part and during the rotation of the control wheel 10 count how many notches are required to get into the desired adjustment position.

Bei darauffolgenden Betätigungen des Möbelantriebs mittels der Handbedieneinrichtung 2 ist es dann lediglich erforderlich, daß der Benutzer das Bedienrad 10 so weit dreht, daß eine entsprechende Anzahl von Rastungen erreicht wurde. Da die Rastpositionen eindeutig unterschiedlichen Verstellhüben der Verstellbewegung zugeordnet sind, ist sichergestellt, daß das Kopfteil dann in die von dem Benutzer gewünschte Position bewegt wird.In subsequent operations of the furniture drive by means of the manual control device 2, it is then only necessary that the user, the operating wheel 10 so far turns that a corresponding number of notches has been achieved. Since the locking positions are assigned clearly different adjustment strokes of the adjustment, it is ensured that the head part is then moved to the position desired by the user.

Um das Kopfteil aus seiner jeweiligen Verstellage zurück in die Ausgangslage zu bewegen, drückt der Benutzer das Bedienrad 10 in Fig. 2 nach unten, so daß der zugeordnete Schalter betätigt wird. Daraufhin wird die Antriebseinheit des Möbelantriebs so angesteuert, daß sie das Kopfteil zurück in die Ausgangslage verstellt. Auf diese Weise ist eine "Reset"-Funktion realisiert.In order to move the head part from its respective adjustment position back to the starting position, the user presses the operating wheel 10 in Fig. 2 down, so that the associated switch is actuated. Then, the drive unit of the furniture drive is driven so that it moves the headboard back to the starting position. In this way, a "reset" function is realized.

Da sich der Benutzer leicht merken kann, welche Anzahl von Rastungen seiner bevorzugten Verstellage beispielsweise des Kopfteiles enspricht, sind bei der erfindungsgemäßen Handbedieneinrichtung 2 aufwendige Memory-Schaltungen nicht erforderlich. Aufgrunddessen ist der erfindungsgemäße Möbelantrieb besonders einfach und kostengünstig herstellbar. Die erfindungsgemäße Handbedieneinrichtung 2 ermöglicht eine besonders intuitive und einfache Bedienung des Möbelantriebs.Since the user can easily remember which number of detents corresponds to his preferred Verstellage example, the head part, 2 complex memory circuits are not required in the manual control device according to the invention. Due to this, the furniture drive according to the invention is particularly simple and inexpensive to produce. The hand-operated device 2 according to the invention allows a particularly intuitive and simple operation of the furniture drive.
