Description

Die vorliegende Erfindung betrifft eine Vorrichtung zur akustischen Signalerzeugung in einem Möbel mit einer elektromechanischen Antriebseinrichtung gemäß dem Oberbegriff des Anspruchs 1 sowie ein Verfahren zur akustischen Signalerzeugung unter Verwendung einer Vorrichtung zur akustischen Signalerzeugung in einem Möbel gemäß dem Oberbegriff des Anspruchs 11.The present invention relates to a device for acoustic signal generation in a piece of furniture with an electromechanical drive device according to the preamble of claim 1 and to a method for acoustic signal generation using a device for acoustic signal generation in a piece of furniture according to the preamble of claim 11.

Es ist bei Möbeln, die mit elektromechanischen Geräten ausgestattet sind, häufig erforderlich, Betriebs- und Fehlerzustände akustisch darzustellen. Hierdurch wird der Anwender beispielsweise auf eine korrekt ausgeführte Funktionsausübung oder auch einen Bedienfehler aufmerksam gemacht. Auch bei zahlreichen Applikationen, beispielsweise bei der Auslösung einer elektromechanischen Auswurfeinrichtung für einen Möbelschubkasten, ist es hilfreich, dem Anwender eine akustische Quittierung seiner Betätigung auszugeben.It is often necessary for furniture equipped with electromechanical devices to acoustically represent operational and fault conditions. As a result, the user is made aware, for example, of a correctly executed function or even an operator error. Even in numerous applications, for example when triggering an electromechanical ejection device for a furniture drawer, it is helpful to give the user an acoustic acknowledgment of its operation.

Zur Ausgabe solcher akustischer Signale werden zum Beispiel bei elektronischen Geräten Lautsprecher bzw. Piezo-Summer verwendet. Nachteilig an der Verwendung solcher Bauteile ist, dass diese in dem Möbel zusätzlichen Bauraum beanspruchen und weitere Kosten verursachen.To output such acoustic signals, speakers or piezo buzzer are used, for example, in electronic devices. A disadvantage of the use of such components is that they claim additional space in the furniture and cause further costs.

Der Erfindung liegt daher die Aufgabe zugrunde, eine platzsparende und kostengünstige Vorrichtung und ein diese Vorrichtung nutzendes einfaches und kostengünstiges Verfahren zur Erzeugung eines akustischen Signals in einem Möbel mit einer elektromechanischen Antriebseinrichtung zu schaffen.The invention is therefore based on the object to provide a space-saving and cost-effective device and a device using this simple and inexpensive method for generating an acoustic signal in a piece of furniture with an electromechanical drive device.

Diese Aufgabe wird durch eine Vorrichtung mit den Merkmalen des Anspruchs 1 und ein Verfahren mit den Merkmalen des Anspruchs 11 gelöst.This object is achieved by a device having the features of claim 1 and a method having the features of claim 11.

Da die erfindungsgemäße Vorrichtung nur Bauteile verwendet, die bereits für andere Zwecke vorhanden sind und auf zusätzliche, Geräusche erzeugende Bauteile, verzichtet, ist diese äußerst platzsparend und besonders kostengünstig.Since the device according to the invention uses only components that are already available for other purposes and on additional noise-generating components omitted, this is extremely space-saving and very cost-effective.

Für die Durchführung des Verfahrens wird die Ansteuerung des Elektromotors variiert, so dass auch hier keine nennenswerten zusätzlichen Kosten anfallen.For the implementation of the method, the control of the electric motor is varied, so that no appreciable additional costs are incurred here.

Weitere vorteilhafte Ausbildungen der Erfindung sind in den Unteransprüchen gekennzeichnet.Further advantageous embodiments of the invention are characterized in the subclaims.

Durch die Ausnutzung des Möbelteils bzw. der Getriebeeinrichtung und dem Möbelkorpus als Resonanzkörper kann auf zusätzliche und damit Platz beanspruchende und Kosten verursachende Bauteile zur Verstärkung des akustischen Signals verzichtet werden.By exploiting the furniture part or the transmission device and the furniture body as a sound box can be dispensed with additional and thus space-demanding and cost-causing components to amplify the acoustic signal.

Mit dem erfindungsgemäßen Verfahren zur Erzeugung eines akustische Signal bevor, während oder im Anschluss an eine Bewegung des Möbelteils kann in einfacher Weise beispielsweise die vom Benutzer aufgerufene Funktion akustisch quittiert, ein aufgetretener Fehler, der korrekte Endzustand oder -ort des Möbelteils oder auch ein niedriger Batteriezustand eines nicht netzgespeisten Gerätes gemeldet werden.With the method according to the invention for generating an acoustic signal before, during or after a movement of the furniture part, the function called up by the user can be acoustically acknowledged, an error occurred, the correct final state or location of the furniture part or even a low battery state of a non-mains powered device.

Figur 1 zeigt schematisiert eine erfindungsgemäße Vorrichtung zur akustischen Signalerzeugung in einem Möbel 1 mit einem Möbelkorpus 11, einem relativ zu dem Möbelkorpus 11 beweglichen Möbelteil 2, und einer elektromechanischen Antriebseinrichtung 3, die einen von einer Steuereinrichtung 7 gesteuerten elektrischen Antrieb 5 und bevorzugt auch eine Getriebeeinrichtung 4 aufweist. Die Drehbewegungen des elektrischen Antriebs 5 wird entweder direkt oder bevorzugt über die Getriebeeinrichtung 4 in translatorische Bewegungen umgewandelt. Die elektromechanische Antriebseinrichtung 3 treibt das bewegliche Möbelteil 2 bevorzugt von einer Rückseite 8 des beweglichen Möbelteils 2 an und ist bevorzugt im Bereich einer Rück- oder Seitenwand des Möbelkorpus 11 angeordnet. Der elektrische Antrieb ist bevorzugt als Elektromotor ausgebildet. FIG. 1 schematically shows an inventive device for acoustic signal generation in a furniture 1 with a furniture body 11, a relative to the furniture body 11 movable furniture part 2, and an electromechanical drive device 3, which has a controlled by a control device 7 electric drive 5 and preferably also a transmission device 4 , The rotational movements of the electric drive 5 is converted either directly or preferably via the transmission device 4 in translational movements. The electromechanical drive device 3 drives the movable furniture part 2 preferably from a rear side 8 of the movable furniture part 2 and is preferably arranged in the region of a rear or side wall of the furniture carcass 11. The electric drive is preferably designed as an electric motor.

In einer bevorzugten Ausführung (nicht gezeigt) ist das bewegliche Möbelteil als Tür oder Klappe ausgebildet. Diese ist mit Schwenkeinriclztungen wie beispielsweise Scharnieren an dem Möbelkorpus 11 gehaltert und mit Hilfe der Getriebeeinrichtung an einer Seitenkante, an der die Schwenkeinrichtungen angeordnet sind oder die der Seitenkante mit den Schwenkeinrichtungen gegenüberliegt, von innen aus dem Möbelkorpus 11 zumindest ein Stück weit herausstoßbar.In a preferred embodiment (not shown), the movable furniture part is designed as a door or flap. This is supported by pivotal arrangements such as hinges on the furniture body 11 and by means of the gear means on a side edge on which the pivoting means are arranged or the side edge with the pivoting means opposite, from the inside out of the furniture carcass 11 at least a little bit herausstoßbar.

In einer anderen bevorzugten Ausführung ist das bewegliche Möbelteil als Schubkasten ausgebildet.In another preferred embodiment, the movable furniture part is designed as a drawer.

Das Möbelteil 2 ist über eine Ausziehführung an dem Möbelkorpus 11 des Möbels 1 ein- und ausfahrbar gelagert. Bevorzugt ist an der Frontseite 9 des Möbelteils 2 eine Bedieneinrichtung 6 zur Eingabe von Bedieninformationen angeordnet, die elektrisch mit der Steuereinrichtung 7 verbunden ist. In dieser Bedieneinrichtung 6 ist ein Auslöser für eine elektromechanische Ausstoßeinrichtung für das Möbelteil 2 enthalten, über den ein Benutzer steuert, ob das Möbelteil 2 ausgestoßen werden soll. In einer anderen bevorzugten Ausführungsform ist das Möbelteil 2 ohne Bedieneinrichtung and dessen Frontseite 9 ausgebildet. Der Auslöser ist bei dieser Ausführungsform direkt an der Ausstoßeinrichtung angeordnet und wird durch Druck auf das Möbeiteil 2 aktiviert. Soll das Möbelteil 2 aus dem Möbelkorpus 11 herausgestoßen werden, so wird diese Information von dem Auslöser weiter an die die Antriebseinrichtung 3 steuernde Steuereinrichtung 7 geleitet. Die Steuereinrichtung 7 wird dadurch so geschaltet, dass sie den elektrischen Antrieb 5 startet, so dass dieser sich für einen bestimmten Zeitraum in eine bestimmte Richtung dreht. Diese Drehung wird von der mit dem elektrischen Antrieb 5 gekoppelten Getriebeeinrichtung 4 und einer mit der Getriebeeinrichtung gekoppelten Mechanik in eine translatorische Bewegung in eine bestimmte Richtung x umgewandelt, die der Ausstoßrichtung des Möbelteils 2 aus dem Möbelkorpus 11 heraus entspricht und das an die Getriebeeinrichtung 4 gekoppelte Möbelteil 2 aus dem Möbelkorpus 11 zumindest ein Stück weit herausstößt.The furniture part 2 is mounted on a pull-out on the furniture body 11 of the furniture 1 and extendable. Preferably, an operating device 6 for inputting operating information is arranged on the front side 9 of the furniture part 2, which is electrically connected to the control device 7. In this operating device 6, a trigger for an electromechanical ejection device for the furniture part 2 is included, via which a user controls whether the furniture part 2 is to be ejected. In another preferred embodiment, the furniture part 2 without control device on the front side 9 is formed. The trigger is arranged directly on the ejection device in this embodiment and is activated by pressure on the furniture part 2. If the furniture part 2 is pushed out of the furniture carcass 11, this information is passed on from the trigger to the control device 7 controlling the drive device 3. The control device 7 is thereby switched so that it starts the electric drive 5 so that it rotates in a certain direction for a certain period of time. This rotation is converted by the coupled to the electric drive 5 gear device 4 and coupled to the transmission mechanism in a translational movement in a certain direction x, which corresponds to the ejection direction of the furniture part 2 from the furniture body 11 out and coupled to the transmission device 4 Furniture part 2 from the furniture body 11 at least a bit protrudes.

Die Steuereinrichtung 7 ist außerdem geeignet, den elektrischen Antrieb 5 zur Erzeugung eines akustischen Signals anzusteuern. Dadurch ist der elektrische Antrieb 5 in dieser Anordnung zusätzlich dazu verwendbar, neben dem oben beschriebenen Antrieb des Möbelteils 2 akustische Signale zu erzeugen, die beispielsweise zur akustischen Wiedergabe bestimmter Positionsstände des Möbelteils 2 oder zur Meldung von Fehlern im Funktionsablauf dienen.The control device 7 is also suitable to control the electric drive 5 to generate an acoustic signal. As a result, the electric drive 5 is additionally usable in this arrangement, in addition to the above-described drive of the furniture part 2 to produce acoustic signals that serve for example for the acoustic reproduction of certain positions of the furniture part 2 or for reporting errors in the functional sequence.

Wie in den Figuren 2 und 3 schematisch dargestellt, wird zur Erzeugung eines akustischen Signals der elektrische Antrieb 5 in geeigneter Weise gesteuert, so dass die an ihn direkt gekoppelte Getriebeeinrichtung 4 und bevorzugt auch der an ihn indirekt über die Getriebeeinrichtung 4 gekoppelte Schubkasten 2 sowie der an diesem befestigte Möbelkorpus 11 in Schwingungen versetzt werden. Auch der Korpus des elektrischen Antriebs 5 selbst kann einen Resonanzkörper zur Erzeugung eines akustischen Signals bilden. D.h. mit anderen Worten, der elektrische Antrieb 5 nutzt die mit ihm gekoppelten Bauteile als Resonanzkörper zur Erzeugung eines akustischen Signals. Dazu wird der elektrische Antrieb 5 während der ersten halben Periode des zu erzeugenden Tones im Linkslauf und während der zweiten halben Periode des zu erzeugenden Tones im Rechtslauf betrieben oder umgekehrt. Der elektrische Antrieb 5 vollzieht hierbei während der kurzen Impulse aufgrund der Massenträgheit nur eine minimale Bewegung, die von außen nicht feststellbar ist. Die auf diese Weise erzeugten Einzelbewegungen in die jeweilige Drehrichtung kompensieren sich in der Summe. Dadurch befindet sich der elektrische Antrieb 5 im Quasistillstand. Dieses schrittweise Vor- und Zurückfahren des elektrischen Antriebs 5 bewirkt eine akustische Erregung des elektrischen Antriebs und der sich mit dem elektrischen Antrieb 5 im Eingriff befindlichen Komponenten in der Weise, dass die Bewegungsenergie in Schallenergie umgewandelt wird. Durch die Kopplung des elektrischen Antriebs 5 mit der Getriebeeinrichtung, dem Möbelteil 2 und dem Möbelkorpus 11 bekommt der elektrische Antrieb 5 als Schall erzeugendes Bauelement den erforderlichen Resonanzkörper.As in the Figures 2 and 3 shown schematically, the electric drive 5 is suitably controlled to generate an acoustic signal, so that the directly coupled to him transmission device 4 and preferably also indirectly coupled to him via the transmission device 4 drawer 2 and attached to this furniture body 11 in vibrations be offset. Also, the body of the electric drive 5 itself can form a sound box for generating an acoustic signal. In other words, the electric drive 5 uses the components coupled with it as a resonance body for generating an acoustic signal. For this purpose, the electric drive 5 is operated clockwise during the first half period of the sound to be generated and clockwise during the second half period of the sound to be generated, or vice versa. The electric drive 5 takes place here during the short pulses due to the inertia only a minimal movement that is not detectable from the outside. The individual movements generated in this way in the respective direction of rotation compensate each other in the sum. As a result, the electric drive 5 is in Quasistillstand. This stepwise driving back and forth of the electric drive 5 causes an acoustic excitation of the electric drive and the components in engagement with the electric drive 5 in such a way that the kinetic energy is converted into sound energy. By the coupling of the electric drive 5 with the transmission device, the furniture part 2 and the furniture body 11 gets the electric drive 5 as a sound-generating component the required sound box.

Bevorzugt wird durch das oben beschriebene Verfahren bereits ein für das menschliche Ohr hörbares akustisches Signal erzeugt. Denkbar ist hier jede Art von akustischen Signalen, da je nach Ansteuerung des elektrischen Antriebs durch Pulsweitenmodulation sowohl die Frequenz als auch die Amplitude des akustischen Signals veränderbar sind.Preferably, an audible signal for the human ear is already generated by the method described above. Conceivable here is any type of acoustic signals, since depending on the control of the electric drive by pulse width modulation, both the frequency and the amplitude of the acoustic signal can be changed.

In einer weiteren besonderen Ausführungsform wird durch das oben beschriebene Verfahren ein Sprachsignal erzeugt. Dadurch kann eine spezifische, für den Benutzer sofort deutbare Meldung ausgegeben werden.In a further particular embodiment, a speech signal is generated by the method described above. As a result, a specific, for the user immediately interpretable message can be issued.

Die Erzeugung des akustisches Signal durch das oben beschriebene Verfahren findet bevorzugt bevor oder im Anschluss an ein Ein- oder Ausfahren eines Schubkastens 2 statt, um beispielsweise die vom Benutzer aufgerufene Funktion akustisch zu quittieren oder den korrekten Endzustand des Möbelteils 2 zu melden,The generation of the acoustic signal by the method described above preferably takes place before or after a retraction or extension of a drawer 2, for example to acoustically acknowledge the function called by the user or to report the correct final state of the furniture part 2,

In einer besonderen Ausführungsform wird während der Bewegung des elektrischen Antriebs 5 zur akustischen Signalerzeugung nach dem oben beschriebenen Verfahren dem Ansteuersignal ein zusätzliches Signal überlagert, so dass das akustische Signal während des Anstoßens des Möbelteils 2 erzeugt wird. Dadurch kann beispielsweise die Bewegung des Möbelteils 2 akustisch hervorgehoben werden.In a particular embodiment, an additional signal is superimposed on the drive signal during the movement of the electric drive 5 for acoustic signal generation according to the method described above, so that the acoustic signal is generated during the abutment of the furniture part 2. As a result, for example, the movement of the furniture part 2 can be highlighted acoustically.

Der elektrische Antrieb 5 übernimmt auf diese Weise eine weitere Funktion, für die ansonsten weitere Bauteile in ein Möbel integriert werden müssten, die Platz beanspruchen und weitere Kosten verursachen würden.The electric drive 5 takes over in this way another function for which otherwise other components would have to be integrated into a piece of furniture that would take up space and cause further costs.
