Description

Die Erfindung bezieht sich auf einen Möbelantrieb mit wenigstens einem elektromechanischen Antriebszug und einer Steuereinheit, die zur Auslösung der Funktionen mittels eines Bedienelementes ansteuerbar ist.The invention relates to a furniture drive with at least one electromechanical Drive train and a control unit used to trigger the functions can be controlled by means of an operating element.

Der in Rede stehende Möbelantrieb kann für Möbel der verschiedensten Art, beispielsweise Betten, Sessel, Patientenlifter und dergleichen eingesetzt werden. Je nach Verwendungszweck ist es ein einfacher Antrieb mit einem elektromechanischen Antriebszug oder ein Doppelantrieb mit zwei elektromechanischen Antriebszügen. Jeder Antriebszug enthält einen Antriebsgetriebemotor, ein Untersetzungsgetriebe, eine rotierend antreibbare Spindel, auf die als Antriebselement für ein zu verstellendes Möbelbauteil eine Spindelmutter aufgesetzt ist.The furniture drive in question can be used for furniture of all kinds, for example Beds, armchairs, patient lifts and the like can be used. Each depending on the purpose, it is a simple drive with an electromechanical Drive train or a double drive with two electromechanical drive trains. Each drive train contains a drive gear motor, a reduction gear, a rotating drivable spindle, on which as a drive element for a to be adjusted Furniture component a spindle nut is placed.

Die bisher bekannten Bedienelemente sind als sogenannte Handschalter ausgebildet. Die Verbindung zur Steuerung erfolgt durch ein Kabel, so daß der Handschalter je nach Länge des Kabels an verschiedenen Stellen im Bereich des Möbels abgelegt werden kann. Der Handschalter ist mit mehreren Drucktastern bestückt, wobei für jede Funktion ein Drucktaster notwendig ist. Demzufolge richtet sich die Anzahl der Drucktaster nach den Verstellmöglichkeiten des Möbels. Damit nicht versehentlich zwei Taster gedrück werden, ist ein Mindestabstand zwischen den beiden Tastern möglich. Im Normalfall sind die Handschalter nicht so ausgelegt, daß beim Auslösen einer Funktion alle anderen Taster verriegelt sind, damit es nicht zu einer Fehlbedienung kommen kann. Fehlbedienungen würden zum Ausfall der Steuerung führen. Um dies zu vermeiden, ist der Aufwand extem groß. Damit insbesondere bei Möbelantrieben für Betten die Handschalter in der Dunkelheit betätigt werden können, ist darüber hinaus eine Beleuchtung notwendig, so daß ständig Strom verbraucht wird. Die Steuerungen sind so ausgelegt, daß nur ein Motor des Möbelantriebes eingeschaltet werden kann. Dies ist jedoch insbesondere bei Möbelantrieben nachteilig, die mit mehr als einem Motor ausgerüstet sind, die zur Funktionserfüllung durchaus gleichzeitig in Betrieb gesetzt werden müssen.The previously known controls are designed as so-called hand switches. The connection to the control is made by a cable, so that the hand switch depending on the length of the cable in different places in the area of the furniture can be. The hand switch is equipped with several push buttons, whereby for every function a push button is necessary. As a result, the number of Push buttons according to the adjustment options of the furniture. Not accidentally two buttons are pressed is a minimum distance between the two buttons possible. In the normal case, the hand switches are not designed so that when triggered one function all other buttons are locked so that it does not result in incorrect operation can come. Incorrect operation would result in the control system failing. To avoid this, the effort is extremely great. So especially at Furniture drives for beds the hand switches are operated in the dark lighting is also necessary so that electricity is constantly being consumed becomes. The controls are designed so that only one motor of the furniture drive can be switched on. However, this is particularly the case with furniture drives disadvantageous, which are equipped with more than one motor, to perform their function must be put into operation at the same time.

Der Erfindung liegt die Aufgabe zugrunde, einen Möbelantrieb der eingangs näher beschriebenen Art so auszubilden, daß das Bedienelement konstruktiv vereinfacht wird und daß Fehlbedienungen weitgehend ausgeschlossen werden können und daß insbesondere auch die Anzahl der für die Auslösung der Funktion notwendigen Elemente verringert wird.The invention has for its object a furniture drive closer to the beginning type described so that the control element simplifies construction will and that incorrect operation can be largely excluded and that especially the number of elements necessary to trigger the function is reduced.

Die gestellte Aufgabe wird gelöst, indem das Bedienelement zur Auslösung mehrerer Funktionen wenigstens einen Schalthebel derart aufweist, daß die jeweilige Funktion durch die Bewegungsrichtung des Schalthebels auslösbar ist.The task is solved by the control element for triggering several Functions has at least one shift lever such that the respective function can be triggered by the direction of movement of the shift lever.

Bei dem Bedienelement des erfindungsgemäßen Möbelantriebes entfallen die bislang verwendeten Drucktaster des Handschalters. Da der Schalthebel je nach Auslegung in einer Vielzahl von vorgegebenen Richtungen bewegbar ist, genügt bei den normalen Möbelantrieben ein Schalthebel. Da sich der Bediener sehr schnell einprägt, welche Funktion durch welche Bewegungsrichtung des Schalthebels ausgelöst wird, kann er betätigt werden, ohne daß man hinschaut, so daß er auch bei Dunkelheit ohne Beleuchtung betätigt werden kann. Da jeweils nur eine Funktion ausgelöst werden kann, kann es nicht zu versehentlichen Fehlbedienungen kommen.The control element of the furniture drive according to the invention has been omitted to date used push button of the hand switch. Because the shift lever depending on the design is movable in a variety of predetermined directions, is sufficient for the normal furniture drives a gear lever. Since the operator memorizes very quickly, which function is triggered by which direction of movement of the shift lever , it can be operated without looking, so that it can be used even in the dark can be operated without lighting. Since only one function was triggered at a time accidental incorrect operation cannot occur.

Ferner ist vorteilhaft, daß das Bedienelement äußerst kompakt ist und daß es fest an einer vorgegebenen Stelle des Möbels montiert werden kann, beispielsweise in der Armlehne eines Sessels. Da es jedoch auch viele Anwendungsfälle gibt, bei denen der Einbau in das Möbel nicht gewollt oder nicht möglich ist, ist in weiterer Ausgestaltung vorgesehen, daß das Bedienelement als Bedienpult ausgebildet ist und mit einem Schalthebel sowie einem Drucktaster als Notausschalteinrichtung ausgerüstet ist. Das Bedienpult läßt sich der Gestaltung eines Möbels optimal anpassen und kann je nach Art des Möbels entweder an geeigneter Stelle abgestellt oder fest montiert werden. Besonders vorteilhaft ist es, wenn der Schalthebel mindestens zwei Druckstufen aufweist, so daß dadurch die Geschwindigkeit des Antriebsgliedes durch eine Änderung der Motordrehzahl verstellt werden kann. Besonders zweckmäßig ist es, wenn das Bedienelement mit einer Anzeige ausgerüstet ist, in der Betriebszustände, Zustände der Akkumulatoren, Fehlermeldungen und dergleichen angezeigt werden können. Zur Versorgung des Möbelantriebs dient eine gemeinsame Stromquelle, die durch verschiedene Quellen entweder einzeln oder kombiniert gebildet werden kann. Als Stromquellen kommen Akkumulatoren, Batterien sowie ein Transformator mit Gleichrichter und Wertungskondensator vorzugsweise in Betracht. Es sind dann verschiedene Kombinationen möglich, wie z. B. ein Akkumulator mit einem Transformator inklusive der Ladeschaltung, ein Akkumulator mit einem externen Ladegerät, ein Akkumulator mit einem externen Ladegerät, welches eine Mindestleistung für den Notbetrieb liefert und ein Netzteil, welches für die Versorgung an den Möbelantrieb angesteckt und in der abgenommenen Stellung eine externe Ladestation bildet.It is also advantageous that the control element is extremely compact and that it is firmly attached a predetermined point of the furniture can be mounted, for example in the Armrest of an armchair. However, since there are also many applications in which The installation in the furniture is not wanted or is not possible in a further embodiment provided that the control element is designed as a control panel and with a switch lever and a push button equipped as an emergency stop device is. The control panel can be optimally adapted to the design of a piece of furniture depending on the type of furniture, either parked at a suitable location or permanently installed become. It when the shift lever is at least two pressure levels is particularly advantageous has, so that thereby the speed of the drive member by a Change in engine speed can be adjusted. It is particularly useful if the control element is equipped with a display in the operating states, States of the accumulators, error messages and the like are displayed can. A common power source is used to supply the furniture drive can be formed by different sources either individually or in combination. Accumulators, batteries and a transformer come as current sources Rectifier and evaluation capacitor are preferably considered. Then they are different Combinations possible, such as B. an accumulator with a transformer including the charging circuit, an accumulator with an external charger Accumulator with an external charger, which has a minimum output for the Emergency operation supplies and a power supply, which for the supply to the furniture drive plugged in and forms an external charging station in the removed position.

Anhand der beiliegenden Zeichnungen wird die Erfindung noch näher erläutert.The invention is explained in more detail with reference to the accompanying drawings.

Es ist ebenfalls denkbar, verschiedene Druckstufen innerhalb des Steuerhebels mechanisch konstruktiv unterzubringen. In weiterer Ausgestaltung sind stufenlose Stellelemente, wie z. B. Potentiometer, Lichtschranken und dergleichen vorgesehen. Um beim zufälligen Berühren des Schalthebels eine Funktionsauslösung zu verhindern, ist der Schalthebel als Sicherheitsschalthebel so gestaltet, daß er erst nach unten gedrückt werden muß und dann in eine funktionsauslösende Richtung verstellt werden kann. Der Schalthebel 11 ist in vielen Ausführungen variierbar, wie die Figur 2 zeigt. So zeigt die Ausführung a der Figur 2, daß der Schalthebel 11 um mehrere Achsen im Punkt M drehbar ist, gemäß der Ausführung b in mehreren Richtungen verschiebbar ist, gemäß der Ausführung c ebenfalls um mehrere Achsen drehbar ist, jedoch daß er als flaches Steuerkreuz ausgebildet ist, während bei der Ausführung nach der Darstellung d er ebenfalls um mehrere Achsen drehbar ist, jedoch als Steuerscheibe ausgebildet ist, bei der Ausführung 3 in mehrere Richtungen verschiebbar ist, jedoch im Gegensatz zur Ausführung b als flacher Kreuzschieber ausgebildet ist und schließlich gemäß der Ausführung f als sogenannter Touchscreen mit zusätzlicher Auswerteelektronik gestaltet ist. Bei der letztgenannten Ausführung enthält er druckempfindliche Bereiche. Die in der Figur 2 unter a und b aufgezeigten Möglichkeiten eignen sich besonders zur Ausgestaltung bzw. für die Variation für behindertengerechte Betätigungshilfen. Der Schalthebel 11 trägt an seinem oberen freien Ende eine Kugel, damit er günstig gegriffen werden kann. Bei den zuvor erwähnten Ausführungen können alle notwendigen Funktionen des Möbelantriebs durch ein einziges Bedienelement ausgelöst werden.The control element of the furniture drive according to the invention is a control panel 10 formed, which in the illustrated embodiment with a shift lever 11 and a push button 12 is equipped. Through the shift lever 11 are preferred Design corresponding to the representations a and b according to FIG. 2 A push button with two pressure levels is operated in each direction in order to increase the speed the output member of the furniture drive or the speed of the drive motor to adjust. It is also conceivable to have different pressure levels within of the control lever to accommodate mechanically constructive. In a further embodiment are stepless control elements, such as B. potentiometers, light barriers and the like provided. In order to accidentally touch the shift lever To prevent the triggering of a function, the gear lever is a safety gear lever designed that it must first be pressed down and then in a function-triggering Direction can be adjusted. The shift lever 11 is in many versions variable, as shown in Figure 2. The execution a of Figure 2 shows that the shift lever 11 is rotatable about several axes at point M, according to the embodiment b can be moved in several directions, likewise in accordance with version c is rotatable about several axes, but that it is designed as a flat control cross is, while in the execution according to the representation he is also around several axes can be rotated, but is designed as a control disk, in the execution 3 can be moved in several directions, but in contrast to Version b is designed as a flat cross slide and finally according to the Version f designed as a so-called touchscreen with additional evaluation electronics is. In the latter version, it contains pressure-sensitive areas. The options shown under a and b in FIG. 2 are particularly suitable for the design or for the variation for disabled aids. The shift lever 11 carries a ball at its upper free end so that it is cheap can be gripped. In the previously mentioned versions, all necessary Furniture drive functions triggered by a single control become.

Der Schalthebel 11 liegt an der Stelle des Bedienpultes, die die geringste Höhe aufweist. Im Bereich der größten Höhe ist der Drucktaster 12 installiert. Der Übergangsbereich ist als Schrägfläche ausgebildet und in diesem Bereich liegt eine Anzeige 13, welche allgemein als Display bezeichnet wird. Das Bedienpunlt 10 kann in die Hand genommen werden, wenn z. B. ein Bediener neben dem Möbel steht, in dem sich eine zu pflegende Person befindet. In weiterer Ausgestaltung kann das Bedienpult z. B. Behinderten auf den Arm geschnallt werden bzw. mittels geeigneter Klemmechanik von Behidnerten selbst in einfacher Weise aufgenommen, befestigt und verwendet werden. Die Steuerung für den nicht dargestellten Möbelanbtrieb befindet sich im Gehäuse 14, das rein schematisch durch den Winkel 14 dargestellt ist. Die Verbindung zum Bedienpult 10 erfolgt durch ein mehradriges Kabel 15, welches mittels einem daran angeordneten Stecker 16 mit einer Ausgangsbuchse 17 der Steuerung 14 verbunden ist. Die Steuerung kann innerhalb des Gehäuses des Möbelantriebs integriert sein, oder in einer außen daran angeordneten Kammer angeordnet sein. Das Kabel 15 ist besonders in einer Spiralausführung hergestellt, so daß ein entferntes Positionieren ermöglicht bzw. erleichtert wird.
