Description

Die vorliegende Erfindung betrifft ein Möbel gemäß den Merkmalen des Oberbegriffs des Anspruchs 1.The present invention relates to a piece of furniture according to the features of the preamble of claim 1.

Ein gattungsgemäßes Möbel gehen beispielsweise aus der WO 2007/009133 A1 der Anmelderin hervor. Diese Schrift hatte es sich zur Aufgabe gemacht, einen Möbelantrieb derart weiterzubilden, dass die Gefahr einer unbeabsichtigten Auslösung verringert wird. Dies wurde derart gelöst, dass ein je nach Öffnungszustand des bewegbaren Möbelteils, nämlich einer Schublade unterschiedlich hoher Schwellwert für die Auslösung des Elektromotors (Auslösesensibilität) vorgesehen war. In der geschlossenen Endlage des bewegbaren Möbelteils war der Schwellwert niedriger als der Schwellwert für die voll geöffnete Endlage des bewegbaren Möbelteils. Dies geht auf die Überlegung zurück, dass das bewegbare Möbelteil in seiner geschlossenen Endlage kaum unbeabsichtigten Krafteinflüssen ausgesetzt ist. In der voll geöffneten Endlage des bewegbaren Möbelteils kann es hingegen zu unbeabsichtigten Krafteinflüssen durch das Be- oder Entladen des bewegbaren Möbelteils mit Füllgütern kommen. Dem wird durch den höher gewählten Schwellwert in dieser Position des bewegbaren Möbelteils Rechnung getragen.A generic furniture go for example from the WO 2007/009133 A1 the applicant. This document has made it its mission to further develop a furniture drive so that the risk of unintentional triggering is reduced. This was solved in such a way that depending on the opening state of the movable furniture part, namely a drawer of different high threshold value for the triggering of the electric motor (trigger sensitivity) was provided. In the closed end position of the movable furniture part, the threshold value was lower than the threshold value for the fully opened end position of the movable furniture part. This is based on the consideration that the movable furniture part is exposed in its closed end position hardly unintentional forces. In the fully open end position of the movable furniture part, however, it can lead to unintentional forces caused by the loading or unloading of the movable furniture part with contents. This is taken into account by the higher selected threshold value in this position of the movable furniture part.

DE 20 2009 009 450 U1 und DE 20 2007 006 689 U1 offenbaren Möbelantriebe für Schiebetüren bzw. Möbelklappen. Aufgabe der Erfindung ist es, ein gattungsgemäßes Möbel bereitzustellen, welches unter Beibehaltung des oben diskutierten Konzeptes eine Alternativlösung darstellt. Diese Aufgabe wird durch ein Möbel mit den Merkmalen des Anspruchs 1 gelöst. Vorteilhafte Ausführungsformen der Erfindung sind in den abhängigen Ansprüchen definiert. DE 20 2009 009 450 U1 and DE 20 2007 006 689 U1 reveal furniture drives for sliding doors or furniture flaps. The object of the invention is to provide a generic furniture, which represents an alternative solution while maintaining the concept discussed above. This object is achieved by a furniture with the features of claim 1. Advantageous embodiments of the invention are defined in the dependent claims.

Die Erfindung beruht auf der überraschenden Erkenntnis, dass es sogar beim Vorsehen zweier baugleicher Sensoren, die jeder für sich genommen dieselbe Auslöseschwelle aufweisen, möglich ist, effektiv eine unterschiedliche Auslösesensibilität zu erzielen, je nachdem, ob sich die bewegbare Schublade in der geschlossenen Endlage befindet oder nicht. Dies wird dadurch erreicht, dass der eine (zweite) Sensor unabhängig vom Getriebe mit einem mechanischen Stellfühler gekoppelt ist und so unmittelbar auf eine externe Krafteinwirkung eines Benutzers auf die bewegbare Schublade reagieren kann. Die Kraftausübung des Benutzers erfolgt dabei bevorzugt nicht unmittelbar auf den mechanischen Stellfühler, sondern indirekt auf die bewegbare Schublade. Da der mechanische Stellfühler zwischen der bewegten Schublade und dem Möbelkorpus angeordnet ist, führt eine Druck- und/oder Zugausübung eines Benutzers auf die bewegbare Schublade zu einer Bewegung des mechanischen Stellfühlers, welche vom entsprechenden (zweiten) Sensor unmittelbar detektiert wird.The invention is based on the surprising realization that it is even possible in the provision of two identical sensors, each of which has the same triggering threshold, to effectively achieve a different triggering sensitivity, depending on whether the movable drawer is in the closed end position or Not. This is achieved by the fact that the one (second) sensor is coupled to a mechanical control sensor independently of the transmission and thus directly on an external force of a user the movable drawer can react. The application of force by the user preferably does not take place directly on the mechanical adjusting sensor, but indirectly on the movable drawer. Since the mechanical adjusting sensor is arranged between the moving drawer and the furniture body, pressing and / or pulling a user on the movable drawer leads to a movement of the mechanical adjusting sensor, which is detected directly by the corresponding (second) sensor.

Der erste Sensor ist hingegen mechanisch mit dem Getriebe gekoppelt. Dadurch ergibt sich eine größere Trägheit, das heißt mit anderen Worten, der Sensor benötigt länger, um der Schalteinrichtung ein Auslösesignal zu übermitteln.The first sensor, however, is mechanically coupled to the transmission. This results in a larger inertia, that is, in other words, the sensor takes longer to transmit a trigger signal to the switching device.

Befindet sich die bewegbare Schublade also in der geschlossenen Endlage im oder am Möbelkorpus und übt ein Benutzer eine Druck- oder Zugausübung auf die bewegbare Schublade aus, so kommt es sowohl zu einer Bewegung des mechanischen Stellfühlers und damit einer Auslösung des zweiten Sensors als auch zu einer Bewegung des Abtriebs und damit des Getriebes und schlussendlich des mit dem Getriebe gekoppelten ersten Sensors. Da der zweite Sensor aber aufgrund seiner unmittelbaren Auslösung schneller auslöst als der erste Sensor, ergibt sich effektiv eine Auslösesensibilität, die der Auslösesensibilität des zweiten Sensors, welche sich aufgrund seiner Bauart ergibt, im Wesentlichen entspricht.Thus, if the movable drawer is in the closed end position in or on the furniture carcass and a user exerts a pressure or pulling action on the movable drawer, both the movement of the mechanical control sensor and thus triggering of the second sensor as well as of a Movement of the output and thus of the transmission and finally the coupled with the transmission first sensor. However, since the second sensor triggers faster than the first sensor because of its immediate triggering, a triggering sensitivity that substantially corresponds to the triggering sensitivity of the second sensor, which results from its design, is effectively obtained.

Befindet sich die bewegbare Schublade nicht in seiner geschlossenen Endlage, das heißt wurde es entweder nur teilweise oder vollständig in Richtung der geöffneten Endlage bewegt, so liegt der mechanische Stellfühler nicht mehr an der Schublade an. Übt nun ein Benutzer eine Druck- oder Zugkraft auf die bewegbare Schublade aus, so kann nur der erste Sensor dies an die Schalteinrichtung melden, da ja der zweite Sensor vom mechanischen Stellfühler kein Signal erhält. In diesem Fall ergibt sich aber eine Auslösesensibilität, die höher ist als in der geschlossenen Endlage, da der erste Sensor, was nicht unbedingt erforderlich ist - auch wenn er baugleich zum zweiten Sensor ist - nur über das Getriebe die Zug- oder Druckausübung des Benutzers detektiert.If the movable drawer is not in its closed end position, that is to say it has either been moved only partially or completely in the direction of the open end position, the mechanical adjusting sensor is no longer in contact with the drawer. If a user exerts a compressive or tensile force on the movable drawer, only the first sensor can report this to the switching device, since the second sensor does not receive a signal from the mechanical position sensor. In this case, however, results in a trigger sensitivity, which is higher than in the closed end position, since the first sensor, which is not absolutely necessary - even if it is identical to the second sensor - detected only via the transmission, the train or pressure application of the user ,

Alternativ oder zusätzlich ist es natürlich möglich, den ersten und den zweiten Sensor nicht baugleich zu wählen, sondern für den ersten Sensor einen Sensor auszuwählen, der von vorneherein eine niedrigere Auslösesensibilität aufweist als der zweite Sensor. Im gewissen Rahmen wäre es sogar möglich, als zweiten Sensor einen solchen Sensor zu wählen, der an sich eine geringere Auslösesensibilität aufweist als der erste Sensor, sofern dies durch die mechanische Kopplung des ersten Sensors mit dem Getriebe überkompensiert wird.Alternatively or additionally, it is of course possible not to select the first and the second sensor identical, but to select a sensor for the first sensor, which from the outset has a lower triggering sensitivity than the second sensor. To a certain extent, it would even be possible to choose as the second sensor such a sensor, which in itself has a lower trigger sensitivity than the first sensor, if this is overcompensated by the mechanical coupling of the first sensor with the transmission.

Der mechanische Stellfühler kann beispielsweise als verschiebbar gelagerter Stößel oder schwenkbar gelagerter Hebel ausgebildet sein, wie dies an sich bekannt ist. Besonders geeignet ist ein schwenkbar gelagerter Hebel, wie er beispielsweise Gegenstand der WO 2010/081178 A1 der Anmelderin ist.The mechanical adjusting sensor may be formed, for example, as a displaceably mounted plunger or pivotally mounted lever, as is known per se. Particularly suitable is a pivotally mounted lever, such as the subject of the WO 2010/081178 A1 the applicant.

Bevorzugt ist eine Steuer- oder Regelvorrichtung für den Elektromotor vorgesehen und besonders bevorzugt ist die Schalteinrichtung in der Steuer- oder Regelvorrichtung ausgebildet. Die Erfindung ermöglicht es aber, gerade keine aufwändige Steuer- oder Regelvorrichtung vorsehen zu müssen und stattdessen nur eine einfache Schalteinrichtung bereitzustellen.Preferably, a control or regulating device for the electric motor is provided, and particularly preferably the switching device is formed in the control or regulating device. The invention makes it possible, however, not to have to provide any elaborate control or regulating device and instead to provide only a simple switching device.

Fig. 1 zeigt in schematischer Form einen Möbelantrieb 1 eines erfindungsgemäßen Möbels. Dieser weist einen Elektromotor 3 auf, der über einen hier als Zahnrad dargestellten Abtrieb 2 ein nicht näher dargestelltes bewegbares Möbelteil, nämlich einer Schublade 11 (siehe zum Beispiel Fig. 2) antreibt. Zwischen Elektromotor 3 und Abtrieb 2 ist ein Getriebe 4 angeordnet bzw. geschalten. Weiters ist eine Schalteinrichtung 5 zum Schalten des Elektromotors 3 vorgesehen. Ein erster Sensor 6 ist mechanisch mit dem Getriebe 4 gekoppelt und führt seine Signale der Schalteinrichtung 5 zu. Ein zweiter Sensor 7 ist mit einem mechanischen Stellfühler 8 gekoppelt und führt ebenfalls seine Signale der Schalteinrichtung 5 zu. Fig. 1 shows in schematic form a furniture drive 1 of a piece of furniture according to the invention. This has an electric motor 3, which via an output shown here as a gear 2, not shown in detail movable furniture part, namely a drawer 11 (see, for example Fig. 2 ) drives. Between the electric motor 3 and output 2, a transmission 4 is arranged or switched. Furthermore, a switching device 5 is provided for switching the electric motor 3. A first sensor 6 is mechanically coupled to the transmission 4 and supplies its signals to the switching device 5. A second sensor 7 is coupled to a mechanical adjusting sensor 8 and also supplies its signals to the switching device 5.

Fig. 2 zeigt in perspektivischer Ansicht ein Beispiel für ein erfindungsgemäßes Möbel 9 mit einem Möbelkorpus 10 und einer bewegbaren Schublade 11, welches durch einen erfindungsgemäßem Möbelantrieb 1 antreibbar ist. Die bewegbare Schublade 11 ist in einer Stellung zwischen der geschlossenen Endlage im Möbelkorpus 10 und der voll geöffneten Endlage dargestellt. Da es sich im vorliegenden Fall um eine grifflose bewegbare Schublade 11 handelt, ist in bekannter Weise auch in der geschlossenen Endlage der bewegbaren Schublade 11 ein geringfügiger Spalt zwischen der Frontblende der bewegbaren Schublade 11 und der Stirnseite des Möbelkorpus 10 vorzusehen, um einen Auslöseweg für die Auslösung des Elektromotors 3 durch Druckausübung auf die Schublade 11 bereitzustellen. Fig. 2 shows a perspective view of an example of an inventive furniture 9 with a furniture body 10 and a movable drawer 11, which is driven by a furniture drive 1 according to the invention. The movable drawer 11 is shown in a position between the closed end position in the furniture body 10 and the fully open end position. Since it is a handleless movable drawer 11 in the present case, a slight gap between the front panel of the movable drawer 11 and the end face of the furniture body 10 is provided in a known manner in the closed end position of the movable drawer 11 to a trip path for the Provide release of the electric motor 3 by applying pressure to the drawer 11.

Fig. 3a zeigt den erfindungsgemäßen Möbelantrieb 1 in Einbaulage der Fig. 2, wobei jedoch aus Gründen der Übersichtlichkeit sowohl der Möbelkorpus 10 als auch die bewegbare Schublade 11 weggelassen wurden. In diesem Ausführungsbeispiel ist ein Möbelantrieb 1 fest mit der bewegbaren Schublade 11 verbunden. Über den beispielsweise in Fig. 5 erkennbaren Abtrieb 2 in Form eines Zahnrades kann der Elektromotor 3 Kraft auf die beispielhaft dargestellte Zahnstange 13 übertragen. Dies führt zu einer Bewegung der bewegbaren Schublade 11. Im gezeigten Ausführungsbeispiel ist nur auf einer Seite der bewegbaren Schublade 11 ein erfindungsgemäßer Möbelantrieb 1 vorgesehen. Um eine gleichmäßige Kraftausübung auf die bewegbare Schublade 11 zu ermöglichen, ist eine an sich bekannte Synchronisationsstange 12 vorgesehen, welche einen Teil der Kraft des Elektromotors 3 auf ein auf der anderen Seite der bewegbaren Schublade 11 angeordnetes weiteres Zahnrades gestattet. Dieses kämmt mit einer weiteren Zahnstange (nicht dargestellt). Fig. 3a shows the furniture drive 1 according to the invention in the installed position of Fig. 2 However, for reasons of clarity, both the furniture body 10 and the movable drawer 11 have been omitted. In this embodiment, a furniture drive 1 is fixedly connected to the movable drawer 11. About the example in Fig. 5 visible output 2 in the form of a gear, the electric motor 3 can transmit power to the exemplary illustrated rack 13. This leads to a movement of the movable drawer 11. In the illustrated embodiment, an inventive furniture drive 1 is provided only on one side of the movable drawer 11. In order to allow a uniform application of force to the movable drawer 11, a known synchronization rod 12 is provided, which allows a portion of the force of the electric motor 3 to a arranged on the other side of the movable drawer 11 further gear. This meshes with another rack (not shown).

Zahnrad und Zahnstange sind nur beispielhaft dargestellt. Es könnte ein völlig anderer Abtrieb 2 eingesetzt werden, beispielsweise in Form eines Reibrades oder in Form eines Seilzuges.Gear and rack are shown only as an example. It could be used a completely different output 2, for example in the form of a friction wheel or in the form of a cable.

In Fig. 3a ist der mechanische Stellfühler 8 gut erkennbar, welcher mit einem am Möbelkorpus 10 angebrachten Anschlag 14 zusammenwirkt. Sowohl ein Andrücken des mechanischen Stellfühlers 8 an den Anschlag 14 als auch ein Abheben von diesem führen zu einer Bewegung des mechanischen Stellfühlers 8, die über einen Zahnradabschnitt 15 (siehe zum Beispiel Fig. 4a) auf das Antriebsrad eines Potentiometers (zweiter Sensor 7) übertragen werden kann.In Fig. 3a is the mechanical control sensor 8 clearly visible, which cooperates with a mounted on the furniture body 10 stop 14. Both a pressing of the mechanical adjusting sensor 8 to the stop 14 and a lifting of this lead to a movement of the mechanical adjusting sensor 8, which via a Gear section 15 (see, for example Fig. 4a ) can be transmitted to the drive wheel of a potentiometer (second sensor 7).

Im Gegensatz dazu ist der erste Sensor 6 (hier als Hallsensor ausgebildet - siehe zum Beispiel Fig. 5b) mechanisch mit dem Getriebe 4 gekoppelt.In contrast, the first sensor 6 (here designed as a Hall sensor - see for example Fig. 5b ) mechanically coupled to the transmission 4.

Das Getriebe 4 hat die Funktion, die Antriebskraft des Elektromotors 3 in geeigneter Übersetzung auf den Abtrieb 2 bzw. die Synchronisationsstange 12 zu übertragen. Dies erfolgt nach der Schnecke 31 des Elektromotors 3 über die Zahnräder 41, 42, 43, 44 und 45. Das letzte Zahnrad 45 kämmt schlussendlich mit dem Abtrieb 2. Die mechanische Kopplung des ersten Sensors 6 mit dem Getriebe 4 erfolgt dabei über das Zahnrad 43 sowie die Zahnräder 62 und 61.The transmission 4 has the function to transmit the driving force of the electric motor 3 in a suitable translation to the output 2 or the synchronization rod 12. This is done by the worm 31 of the electric motor 3 via the gears 41, 42, 43, 44 and 45. The last gear 45 finally meshes with the output 2. The mechanical coupling of the first sensor 6 with the gear 4 takes place via the gear 43 and the gears 62 and 61.

Im gezeigten Ausführungsbeispiel weist der Möbelantrieb 1 eine Regelvorrichtung auf, in welcher die Schalteinrichtung 5 ausgebildet ist. Diese ist auf einer in den Figuren nicht näher dargestellten Platine in bekannter Weise angeordnet.In the exemplary embodiment shown, the furniture drive 1 has a control device in which the switching device 5 is formed. This is arranged on a non-illustrated in the figures board in a known manner.

Dem Fachmann bekannte Maßnahmen wie Stromzuführung wurden nicht dargestellt.The skilled person known measures such as power supply were not shown.
