Abstract

The furniture drawer (2) can be mounted in a furniture carcass in a manner such that it can be pilled out. An electrical energy transmitter is provided to send electrical energy to the rechargeable battery (3) arranged in or on the drawer. An Independent claim is included for the furniture to which the furniture is installed.

Description

Die Erfindung betrifft eine Möbelschublade, mit dem Merkmalen des Oberbegriffs des Anspruchs 1 und ein Möbel mit mindestens einer solchen ausziehbaren Möbelschublade.The invention relates to a furniture drawer, with the features of the preamble of claim 1 and a piece of furniture with at least one such pull-out furniture drawer.

Um ständige Leitungen in Form von elektrischen Kabeln vom Möbelkorpus zur Schublade zu vermeiden, ist eine Möbelschublade vorgesehen, die gekennzeichnet ist durch die Merkmale des Kennzeichens des Anspruchs 1.To avoid permanent lines in the form of electrical cables from the furniture body to the drawer, a furniture drawer is provided, which is characterized by the features of the characterizing part of claim 1.

Mittels solcher aufladbarer Stromspeicher ist es möglich, für die Schublade bzw. darin befindliche elektrische Geräte, vorzugsweise Haushaltsgeräte, eine autonome Energieversorgung bereitzustellen, wobei vorzugsweise nur bei geschlossener Schublade eine elektrische Energieübertragung zur Aufladung der aufladbaren Stromspeicher erfolgt. Bei ausgezogener Schublade können dann die aufgeladenen Stromspeicher elektrische Verbraucher, wie beispielsweise Lampen oder Antriebsmotoren, versorgen bzw. in der Schublade befindliche, bei geschlossener Schublade aufgeladene Haushaltsgeräte entnommen werden.By means of such rechargeable power storage, it is possible for the drawer or therein electrical appliances, preferably household appliances, to provide an autonomous power supply, preferably only when the drawer is closed, an electrical energy transfer for charging the rechargeable power storage. When the drawer is pulled out, the charged power stores can then supply electrical consumers, such as, for example, lamps or drive motors, or they can be removed from the drawer and charged with the drawer closed.

Zur Realisierung einer solchen Einrichtung zur Übertragung elektrischer Energie ist bevorzugt an der Schubladenhinterwand ein berührungsloser Übertrager, vorzugsweise ein induktiver Koppler oder ein Steckkontakt vorgesehen, der bei geschlossener Schublade automatisch mit einem korpusseitigen Kontakt in Verbindung tritt. Die Stromversorgung erfolgt beispielsweise vom üblichen Wechselstromnetz aus über einen Transformator, der im Bereich der Schublade einen für den Menschen ungefährlichen Niedervoltbereich vorzugsweise unter 25 Volt herstellt.To realize such a device for the transmission of electrical energy, a non-contact transmitter, preferably an inductive coupler or a plug contact, is preferably provided on the rear wall of the drawer, which automatically comes into contact with a body-side contact when the drawer is closed. The power supply takes place, for example, from the usual AC power supply via a transformer, which preferably produces below 25 volts in the area of the drawer, a harmless low-voltage range for humans.

Die genannten elektrischen induktiven Übertrager sind an sich bereits bekannt, beispielsweise bei elektrischen Zahnbürsten, und brauchen daher nicht näher beschrieben werden.The said electrical inductive transformers are already known, for example in electric toothbrushes, and therefore need not be described in detail.

Die aufladbaren Stromspeicher sind platzgünstig in der Schubladenwand bzw. im Schubladenboden eingebaut bzw. integriert.The rechargeable power storage units are conveniently installed or integrated in the drawer wall or in the drawer bottom.

Es ist möglich, die üblicherweise metallischen Führungsschienen zur Stromübertragung in die Schublade zu verwenden, wobei dabei günstigerweise Schleifkontakte vorgesehen sind, um die korpusseitige Führungsschiene, die mit einer Stromquelle verbunden ist, mit der schubladenseitigen Führungsschiene zu verbinden.It is possible to use the usually metallic guide rails for power transmission in the drawer, wherein thereby sliding contacts are conveniently provided to connect the body-side guide rail, which is connected to a power source, with the drawer-side guide rail.

Bei Verwendung solcher elektrischer Führungsschienen können Kabel vermieden werden.When using such electrical guide rails cables can be avoided.

Vielmehr können elektrische Verbraucher wie beispielsweise Lampen oder Motoren ständig auch direkt versorgt werden. Natürlich können über solche elektrifizierten Führungsschienen auch Haushaltsgeräte im Inneren der Schublade, die einen Akku aufweisen, geladen werden.Rather, electrical consumers such as lamps or motors can constantly be supplied directly. Of course, such electrified guide rails and home appliances inside the drawer, which have a battery can be charged.

Eine besonders vorteilhafte Ausführungsbeispiel der Erfindung ergibt sich dadurch, daß mindestens eine Lichtquelle als Leuchtdiode (LED) ausgeführt ist. Leuchtdioden vereinen eine kompakte Bauweise mit einer guten Lichtausbeute bei geringem Strombedarf.A particularly advantageous embodiment of the invention results from the fact that at least one light source is designed as a light emitting diode (LED). Light-emitting diodes combine a compact design with a good light output with low power consumption.

Neben der Versorgung aus dem üblichen Stromnetz ist gemäß einer weiteren Variante der Erfindung vorgesehen, daß an der Schublade bzw. am Möbelkorpus eine Solarzelle vorgesehen ist. Über eine solche ist kostengünstig und vor allem ohne die Notwendigkeit einer Netzverbindung eine Stromversorgung von elektrischen Verbraucher in bzw. an der Schublade möglich, wobei ein wiederaufladbarer Stromspeicher vorgesehen ist, der über die Solarzelle und einen entsprechenden Laderegler geladen wird.In addition to the supply from the usual power supply, it is provided according to a further variant of the invention that a solar cell is provided on the drawer or on the furniture carcass. About such is a cost and especially without the need for a network connection, a power supply of electrical loads in or on the drawer possible, with a rechargeable power storage is provided, which is charged via the solar cell and a corresponding charge controller.

Eine besonders vorteilhafte Ausführungsform der Erfindung ergibt sich dadurch, daß mindestens ein Stromspeicher eine aufladbare Batterie ist. Solche aufladbaren Batterien sind in vielen verschiedenen Ausführungsformen erhältlich, sodaß abhängig vom voraussichtlichen Strombedarf und des zur Verfügung stehenden Platzes eine geeignete aufladbare Batterie gewählt werden kann.A particularly advantageous embodiment of the invention results from the fact that at least one power storage is a rechargeable battery. Such rechargeable batteries are available in many different embodiments, so that a suitable rechargeable battery can be selected depending on the anticipated power requirements and the available space.

Eine weitere vorteilhafte Ausführungsform der Erfindung ergibt sich dadurch, daß mindestens ein aufladbarer Stromspeicher ein Kondensator ist. Auch nach längerer Benutzung ist bei einem Kondensator so gut wie keine Abnahme des Speichervermögens festzustellen, da z.B. anders als bei Akkumulatoren keine das Speichervermögen reduzierende Memoryeffekte auftreten.A further advantageous embodiment of the invention results from the fact that at least one rechargeable power storage is a capacitor. Even after prolonged use, there is almost no decrease in the storage capacity of a capacitor since, e.g. unlike accumulators, memory memory-reducing memory effects do not occur.

Der in Fig. 1 dargestellte Möbelkorpus 1 weist vier ausziehbare Schubladen 2 auf, die jeweils in der Rückwand einen wiederaufladbaren Akkumulator (wiederaufladebare Batterie) aufweisen. In der Schubladenseitenwand (Schubladenzarge 4) ist eine schematisch dargestellte Beleuchtung 5 (in der Praxis beispielsweise eine längliche Leuchtstoffröhre) vorgesehen, die über einen transparenten Abschnitt das Innere der Schublade beleuchtet. Die Stromversorgung dieser Lampe 5 erfolgt von der wiederaufladbaren Batterie 3 aus, die, wie bereits erwähnt, in der Schubladenhinterwand 6 integriert ist. Zum Aufladen dieser wiederaufladbaren Batterie 3 ist eine im folgenden noch näher beschriebene Einrichtung zur Übertragung von elektrischer Energie bei geschlossener Schublade vorgesehen. Diese Energie kann beispielsweise aus Solarzellen 7 auf der Oberseite des Möbelkorpus oder über einen Stecker 8, einen Trafo 9 und Leitungen 10 aus dem üblichen Stromnetz erfolgen.The in Fig. 1 illustrated furniture body 1 has four pull-out drawers 2, each having a rechargeable battery (rechargeable battery) in the back wall. In the drawer side wall (drawer 4) is a schematically illustrated illumination 5 (in practice, for example, an elongated fluorescent tube) is provided, which illuminates the interior of the drawer via a transparent section. The power supply of this lamp 5 takes place from the rechargeable battery 3, which, as already mentioned, is integrated in the drawer rear wall 6. For charging this rechargeable battery 3, a device described in more detail below for the transmission of electrical energy is provided with a closed drawer. This energy can be done for example from solar cells 7 on top of the furniture body or a plug 8, a transformer 9 and lines 10 from the usual power grid.

Die Leitungen im Inneren des Möbelkorpusses sowie zwischen der wiederaufladbaren Batterie und der Lampe 5 sind nicht näher dargestellt. Sie können platzgünstig und vorzugsweise unsichtbar verlegt sein. Auch Schalter, die die Beleuchtung nur bei ausgezogener Schublade einschalten, sind nicht näher dargestellt. Sie können beispielsweise an der Schubladenrückwand befestigt sein und ähnlich wie beim Öffnen einer Kühlschranktür die Beleuchtung einschalten. Die Versorgung über die Solarzelle 7 bzw. das öffentliche Stromnetz kann alternativ oder gleichzeitig vorgesehen sein, wobei eine nicht näher dargestellte Elektronik bei mangelndem Licht für die Solarzelle das öffentliche Stromnetz heranzieht. Damit kann Energie gespart werden. Bei geringen elektrischen Verbrauchen kann aber auch die Solarzelle alleine ausreichen.The lines inside the furniture body and between the rechargeable battery and the lamp 5 are not shown in detail. They can be laid in a space-saving and preferably invisible way. Even switches that turn on the lights only when the drawer is pulled out, are not shown in detail. For example, they may be attached to the drawer rear panel and, similar to opening a refrigerator door, turn on the lights. The supply via the solar cell 7 or the public power grid can be provided alternatively or simultaneously, with a not-shown electronics in the lack of light for the solar cell uses the public power grid. This can save energy. With low electrical consumption, however, the solar cell alone can be sufficient.

Bei dem in den Fig. 2a, 2b und 2c dargestellten Ausführungsbeispiel ist die wiederaufladbare Batterie 3 im Schubladenboden 11 integriert. Die Einrichtung zur Übertragung von elektrischer Energie besteht hier aus einem zweiteilig ausgeführten induktiven Koppler 12a, 12b, der bei geschlossener Schublade eine elektrische Energieübertragung erlaubt und damit über die Leitung 13 den Akku aufladen kann. Die Stromversorgung von außen erfolgt über die Leitung 10, beispielsweise vom öffentlichen Stromnetz aus, über einen Transformator oder von einer Solarzelle. Der induktive Koppler selbst erlaubt eine berührungslose elektrische Übertragung und ist, wie bereits erwähnt, beispielsweise bei elektrischen Zahnbürsten bereits bekannt. Er ist auch bei vielfachem Öffnen und Schließen der Schublade absolut verschleißarm. Bei ausgezogener Schublade, wie in Fig. 2, ist die Schublade von der Leitung 10 getrennt. Die Stromversorgung von hier nicht näher dargestellten Verbrauchern, beispielsweise Lampen, Antriebsmotoren oder dergleichen, erfolgt dann über den aufgeladenen Akku 3.In the in the Fig. 2a, 2b and 2c illustrated embodiment, the rechargeable battery 3 is integrated in the drawer bottom 11. The device for transmitting electrical energy here consists of a two-part inductive coupler 12a, 12b, which allows an electric power transmission when the drawer is closed and thus can charge the battery via the line 13. The power supply from the outside via the line 10, for example, from the public power grid, a transformer or a solar cell. The inductive coupler itself allows a contactless electrical transmission and, as already mentioned, for example, in electric toothbrushes already known. It is absolutely wear-resistant even with multiple opening and closing of the drawer. With the drawer pulled out, as in Fig. 2 , the drawer is disconnected from the line 10. The power supply of consumers not shown here, such as lamps, drive motors or the like, then takes place via the charged battery. 3

Bei dem in den Fig. 3a, 3b und 3c dargestellten Ausführungsbeispiel ist ebenfalls im Boden 11 der Schublade ein Akku 3 vorgesehen, der über einen Laderegler 14 von einem Solarzellenpanneel 15 an der Frontblende 2a der Schublade aufladbar ist.In the in the Fig. 3a, 3b and 3c illustrated embodiment, a battery 3 is also provided in the bottom 11 of the drawer, which is chargeable via a charge controller 14 of a solar cell panel 15 on the front panel 2a of the drawer.

Bei dem in den Fig. 4a und 4b dargestellten Ausführungsbeispiel ist in der Aufsatzzarge 4a' eine längliche Leuchtstoffröhre 5 eingebaut, die Wände 16 der Aufsatzzarge können zumindest auf der Innenseite der Schublade transparent ausgeführt sein, um den Innenraum der Schublade beleuchten zu können. Die Wände 16 sind profiliert und halten über ihre profilierten Abschnitte zusammen, wobei im oberen Bereich ein Halteteil, beispielsweise aus Aluminium, vorgesehen ist, der in eine übliche Schubladenreling 18 einhängbar ist. Die ganze Aufsatzzarge 4a' ist auf die eigentliche Schubladenzarge 4a aufsetzbar und wird oben von der Reling 18 gehalten.In the in the Fig. 4a and 4b illustrated embodiment, an elongated fluorescent tube 5 is installed in the top frame 4a ', the walls 16 of the top frame can be made transparent at least on the inside of the drawer to illuminate the interior of the drawer can. The walls 16 are profiled and hold together over their profiled sections, wherein a holding part, for example made of aluminum, is provided in the upper region, which can be suspended in a conventional drawer rail 18. The entire top frame 4a 'is placed on the actual drawer 4a and is held at the top of the rail 18.

Bei dem Ausführungsbeispiel der Fig. 4a und 4b sind der Einfachheit halber elektrische Leitungen, der wiederaufladbare Stromspeicher sowie allfällige Schalter nicht dargestellt.In the embodiment of the Fig. 4a and 4b For the sake of simplicity, electrical lines, the rechargeable power store and any switches are not shown.

Die Fig. 5 zeigt ein Ausführungsbeispiel, bei dem die Einrichtung zur Übertragung der elektrischen Energie vom Möbelkorpus 1 an die Schublade 2 über einen mechanischen Steckkontakt 12a', 12b' erfolgt, der bei geschlossener Schublade automatisch einen elektrischen Kontakt herstellt. In der Möbelhinterwand 6 ist wiederum ein wiederaufladbarer Stromspeicher in Form einer aufladbaren Batterie 3 integriert, die über Schalter 22 und Leitungen 23 im Boden 11 der Schublade einen elektrischen Antriebsmotor 24 versorgt. Dieser trägt ein Ritzel 25, das in eine Zahnstange 26 an der korpusseitigen Schiene eingreift und damit einen Antrieb der Schublade ermöglicht. Die üblichen Laufrollen bzw. Gleiter zwischen der korpusseitigen Führungsschiene 27 und der ladenseitigen Führungsschiene 28 sind der Einfachheit halber nicht dargestellt. Sie entsprechen dem heutigen Industriestandard. Bei dem in Fig. 5 dargestellten Ausführungsbeispiel ergibt sich also eine autonom verfahrbare selbst angetriebene Schublade ohne störende bewegte Kabel zur Stromversorgung des Antriebsmotors 24.The Fig. 5 shows an embodiment in which the means for transmitting the electrical energy from the furniture body 1 to the drawer 2 via a mechanical plug contact 12a ', 12b' takes place, which automatically produces an electrical contact with the drawer closed. In the furniture rear wall 6, in turn, a rechargeable power storage in the form of a rechargeable battery 3 is integrated, which supplies an electric drive motor 24 via switch 22 and lines 23 in the bottom 11 of the drawer. This carries a pinion 25 which engages in a rack 26 on the body side rail and thus allows a drive of the drawer. The usual rollers or sliders between the body-side guide rail 27 and the loading-side guide rail 28 are not shown for the sake of simplicity. They comply with today's industry standard. At the in Fig. 5 illustrated embodiment thus results in an autonomously movable self-powered drawer without disturbing moving cables for powering the drive motor 24th

Bei dem in Fig. 6 dargestellten Ausführungsbeispiel ist die korpusseitig befestigte Führungsschiene 27 an der Stelle 29 mit der Versorgungsleitung 10 (Pluspol) elektrisch kontaktiert. Von der Schublade 2 ist der Boden 11 und die Seitenwand 4a auf einer Seite dargestellt. Mit der Schublade verbunden ist die schubladenseitige Führungsschiene 28, die über stark schematisch dargestellte Rollen, Wälzlager oder Gleitlager 30 gegenüber der Ladenschiene 27 ausziehbar ist. Um nun ständig einen elektrischen Kontakt zwischen der kontaktierten korpusseitigen Führungsschiene 27 und der schubladenseitigen Führungsschiene 28 herzustellen, ist ein Schleifkontakt 31 vorgesehen, der in jeder Auszugsstellung, insbesondere auch bei geschlossener Schublade, einen Kontakt zum Inneren der Schublade herstellt. Über den Kontaktpunkt 29' und das Kabel 21 kann die wiederaufladbare Batterie 3 geladen werden. Anders als dargestellt, soll diese platzgünstig im Schubladenboden 11 integriert sein. Der andere Pol wird über die Leitung 21' über das rechte, hier nicht dargestellte analoge System an Führungsschienen ständig kontaktiert.At the in Fig. 6 illustrated embodiment, the body side mounted guide rail 27 is contacted at the point 29 to the supply line 10 (positive pole) electrically. From the drawer 2, the bottom 11 and the side wall 4a is shown on one side. Connected to the drawer is the drawer-side guide rail 28, which can be pulled out of the drawer rail 27 via rollers, roller bearings or slide bearings 30, which are shown in a highly schematic manner. In order to produce an electrical contact between the contacted body-side guide rail 27 and the drawer-side guide rail 28, a sliding contact 31 is provided, which makes contact with the interior of the drawer in each extension position, especially when the drawer is closed. Via the contact point 29 'and the cable 21, the rechargeable battery 3 can be charged. Unlike shown, this should be conveniently integrated into the drawer bottom 11. The other pole is constantly contacted via the line 21 'via the right, not shown here analogous system of guide rails.

Das in den Fig. 7a, 7b und 7c dargestellte Ausführungsbeispiel unterscheidet sich von dem in den Fig. 2a, 2b und 2c dargestellten dadurch, daß anstelle einer wiederaufladbaren Batterie 3 eine Anordnung von fünf vorzugsweise parallel geschalteten Kondensatoren 32 im Schubladenboden 11 integriert ist. Es können beispielsweise kommerziell erhältliche Kondensatoren mit typischen Abmessungen im Zentimeterbereich und mit einer Kapazität von je in der Größenordnung von 50-500 µF verwendet werden. Diese reichen aus, um beispielsweise Lichtquelle über eine typische Öffnungsdauer von Schubladen zu betreiben.That in the Fig. 7a, 7b and 7c illustrated embodiment differs from that in the Fig. 2a, 2b and 2c represented by the fact that instead of a rechargeable battery 3, an arrangement of five preferably parallel-connected capacitors 32 in the drawer bottom 11 is integrated. For example, commercially available capacitors with typical dimensions in the centimeter range and with a capacitance of the order of 50-500 μF each can be used. These are sufficient, for example, to operate light source over a typical opening duration of drawers.
