Description

Die vorliegende Erfindung betrifft ein Möbel mit einem Möbelkorpus, an dem ein Schubkasten und mindestens ein Innenschubkasten verfahrbar gehalten sind, wobei der mindestens eine Innenschubkasten in einer Schließposition von einer Frontblende des Schubkastens zumindest teilweise verdeckt ist, und der mindestens eine Innenschubkasten über mindestens eine Ausstoßvorrichtung nach einem Entriegeln einer Verriegelungseinrichtung der Ausstoßvorrichtung durch Bewegen eines durch einen Kraftspeicher angetriebenen Antriebselements auswerfbar ist, und ein Verfahren zum Öffnen eines Schubkastens und eines Innenschubkastens an einem Möbel.The present invention relates to a piece of furniture with a furniture body on which a drawer and at least one inner drawer are movably held, the at least one inner drawer being at least partially covered in a closed position by a front panel of the drawer, and the at least one inner drawer via at least one ejector device an unlocking of a locking device of the ejection device can be ejected by moving a drive element driven by an energy storage device, and a method for opening a drawer and an inner drawer on a piece of furniture.

Die EP 1 901 633 B1 offenbart ein Möbel, das einen Schubkasten und einen Innenschubkasten aufweist, die jeweils über eine Ausstoßvorrichtung von einer Schließstellung in eine Offenstellung auswerfbar sind. Die beiden Ausstoßvorrichtungen sind über ein Schaltelement miteinander verbunden, um über eine Steuer- oder Regeleinrichtung die Schubladen zu bewegen. Der Einsatz von elektrischen Antrieben und einer Steuereinrichtung ist allerdings vergleichsweise aufwändig und führt zu einem unerwünschten Energieverbrauch. Zudem ist die Handhabung für den Benutzer nicht intuitiv verständlich.The EP 1 901 633 B1 discloses a piece of furniture that has a drawer and an inner drawer, each of which can be ejected from a closed position into an open position via an ejector device. The two ejection devices are connected to one another via a switching element in order to move the drawers via a control or regulating device. The use of electric drives and a control device is, however, comparatively complex and leads to undesirable energy consumption. In addition, the handling is not intuitively understandable for the user.

US 2006/0218958 offenbart einen Kühlschrank für Weinflaschen, der einen Schubkasten mit mehreren Innenschubkästen offenbart, die über einen Mitnehmer miteinander koppelbar sind. US 2006/0218958 discloses a refrigerator for wine bottles which discloses a drawer with a plurality of inner drawers which can be coupled to one another via a driver.

EP 2 401 940 A1 offenbart ein Möbel mit zwei ausfahrbaren Möbelelementen, die miteinander gekoppelt sind, so dass bei einem Ausfahren eines Möbelelementes das andere Möbelelement über einen Antrieb ausgefahren wird. EP 2 401 940 A1 discloses a piece of furniture with two extendable furniture elements which are coupled to one another so that when one furniture element is extended, the other furniture element is extended via a drive.

Es ist daher Aufgabe der vorliegenden Erfindung, ein Möbel und ein Verfahren zum Öffnen eines Schubkastens und eines Innenschubkastens zu schaffen, die ein einfaches Öffnen des Innenschubkastens ermöglichen und eine verbesserte Handhabung aufweisen.It is therefore the object of the present invention to create a piece of furniture and a method for opening a drawer and an inner drawer, which enable the inner drawer to be opened easily and which have improved handling.

Diese Aufgabe wird mit einem Möbel mit den Merkmalen des Anspruches 1 sowie einem Verfahren mit den Merkmalen des Anspruches 11 gelöst.This object is achieved with a piece of furniture with the features of claim 1 and a method with the features of claim 11.

Bei dem erfindungsgemäßen Möbel ist sowohl ein Schubkasten als auch mindestens ein Innenschubkasten vorgesehen, wobei der mindestens eine Innenschubkasten über mindestens eine Ausstoßvorrichtung auswerfbar ist, die über einen mit dem Schubkasten oder mit einem mit dem Schubkasten verbundenen Bauteil angeordneten Aktivator auslösbar ist, indem der Aktivator in einer vorbestimmten Öffnungsposition des Schubkastens die Verriegelungseinrichtung der Ausstoßvorrichtung des Innenschubkastens entriegelt. Dadurch kann eine mechanische Entriegelung der Ausstoßvorrichtung für den Innenschubkasten durch eine Bewegung des Schubkastens bewirkt werden, was die Handhabung vereinfacht. Der Benutzer muss lediglich den Schubkasten öffnen und kann in einer vorbestimmten Öffnungsposition damit auch den Innenschubkasten über die Ausstoßvorrichtung auswerfen. Auch das Auswerfen erfolgt mechanisch über einen durch einen Kraftspeicher angetriebenen Antriebselement der Ausstoßvorrichtung.In the furniture according to the invention, both a drawer and at least one inner drawer are provided, wherein the at least one inner drawer can be ejected via at least one ejection device which can be triggered via an activator arranged with the drawer or with a component connected to the drawer by the activator in a predetermined opening position of the drawer unlocks the locking device of the ejection device of the inner drawer. This allows a mechanical unlocking of the ejection device for the inner drawer can be effected by moving the drawer, which simplifies handling. The user only has to open the drawer and can also eject the inner drawer via the ejection device in a predetermined opening position. The ejection also takes place mechanically via a drive element of the ejection device that is driven by an energy storage device.

Vorzugsweise ist am Schubkasten oder an einer Laufschiene einer Auszugsführung der Aktivator vorgesehen, der mit den Betätigungsmitteln zum Entriegeln der Verriegelungseinrichtung in Eingriff bringbar ist. Dadurch kann der Aktivator in Öffnungsrichtung und Schließrichtung bewegt werden und in einer vorbestimmten Öffnungsposition eine Entriegelung der Ausstoßvorrichtung bewirken. Die Betätigungsmittel sind dann stationär angeordnet und können über den Aktivator betätigt werden, beispielsweise kann ein aus Stangen gebildetes Getriebe bewegt werden, insbesondere können die Stangen gedreht werden. Alternativ kann auch ein Bowdenzug oder ein aus anderen Elementen gebildetes Getriebe eine Bewegung durch den Aktivator zu der Ausstoßvorrichtung übertragen. Vorzugsweise weisen die Betätigungsmittel einen verschwenkbaren Hebel auf, der beim Überfahren des Aktivators verschwenkt wird, so dass ein zuverlässiges Auslösen an einer vorbestimmten Position gewährleistet ist. Der Hebel kann dabei über eine Feder in eine Ausgangsposition vorgespannt sein, so dass auch eine Rückstellung des Hebels automatisch erfolgt.Preferably, the activator is provided on the drawer or on a running rail of a pull-out guide, which activator can be brought into engagement with the actuating means for unlocking the locking device. As a result, the activator can be moved in the opening direction and the closing direction and can unlock the ejector device in a predetermined opening position. The actuating means are then arranged in a stationary manner and can be actuated via the activator, for example a gear made up of rods can be moved, in particular the rods can be rotated. Alternatively, a Bowden cable or a transmission formed from other elements can also transmit a movement through the activator to the ejector device. The actuating means preferably have a pivotable lever which is pivoted when the activator is passed over, so that reliable triggering at a predetermined position is ensured. The lever can be biased into an initial position by a spring, so that the lever is also automatically reset.

In einer weiteren Ausgestaltung ist ein Selbsteinzug vorgesehen, der in einem Schließbereich den Innenschubkasten in eine Schließposition zieht und dort hält, und ein Spannen des Kraftspeichers der Ausstoßvorrichtung im Wesentlichen vor dem Schließbereich erfolgt. Diese Kombination der Ausstoßvorrichtung mit einem Selbsteinzug vereinfacht die Handhabung, wobei eine Ausstoßvorrichtung hierfür beispielsweise so ausgebildet sein kann, wie dies in der DE 10 2016 113 044 offenbart ist.In a further embodiment, a self-closing mechanism is provided, which pulls the inner drawer into a closed position in a closing area and holds it there, and tensioning the energy store of the ejector device takes place essentially in front of the closing area. This combination of the ejector with a self-retraction simplifies handling, with an ejector for this purpose being designed, for example, as shown in FIG DE 10 2016 113 044 is revealed.

Vorzugsweise erfolgt eine Betätigung der Betätigungsmittel, wenn der Schubkasten mindestens die halbe Wegstrecke bis zur maximalen Öffnungsposition zurückgelegt hat. Dadurch kann der Benutzer zunächst den Schubkasten öffnen, der dann zumindest teilweise zugänglich ist, und erst bei einem Öffnen nach der halben Wegstrecke bis zur maximalen Öffnungsposition, vorzugsweise erst nach 2/3 oder 3/4 der Wegstrecke bis zur maximalen Öffnungsposition, wird der Innenschubkasten entriegelt und ausgeworfen. Es ist auch möglich, den Innenschubkasten erst dann auszulösen, wenn der Schubkasten gerade die maximale Öffnungsposition erreicht, so dass der Benutzer beim Öffnen des Schubkastens entscheiden kann, ob zusätzlich auch der Innenschubkasten geöffnet werden soll.The actuating means are preferably actuated when the drawer has covered at least half the distance to the maximum opening position. As a result, the user can first open the drawer, which is then at least partially accessible, and only when it is opened halfway up to the maximum opening position, preferably only after 2/3 or 3/4 of the distance up to the maximum opening position, the inner drawer becomes unlocked and ejected. It is also possible, to trigger the inner drawer only when the drawer has just reached the maximum opening position, so that the user can decide when opening the drawer whether the inner drawer should also be opened.

Um auch hohe Gewichte an dem Innenschubkasten aufnehmen zu können, sind vorzugsweise zwei Ausstoßvorrichtungen an dem Innenschubkasten vorgesehen, die über Synchronisationsmittel synchronisiert sind, also bei einer Entriegelung einer Verriegelungseinrichtung einer Ausstoßvorrichtung über die Synchronisationsmittel auch gleichzeitig eine Entriegelung der Verriegelungseinrichtung der anderen Ausstoßvorrichtung bewirkt wird. Dadurch können zwei über Kraftspeicher vorgespannte Antriebselemente den Innenschubkasten in Öffnungsrichtung auswerfen.In order to be able to accommodate heavy weights on the inner drawer, two ejection devices are preferably provided on the inner drawer, which are synchronized via synchronization means, i.e. when a locking device of an ejection device is unlocked via the synchronization means, the locking device of the other ejection device is unlocked at the same time. As a result, two drive elements pre-tensioned via energy storage devices can eject the inner drawer in the opening direction.

Zudem ist es möglich, dass auch der Schubkasten über eine oder zwei Ausstoßvorrichtungen auswerfbar ist. Optional kann der Schubkasten auch manuell in Öffnungsrichtung über einen Griff ohne Ausstoßvorrichtung bewegt werden.It is also possible for the drawer to be ejected via one or two ejection devices. Optionally, the drawer can also be moved manually in the opening direction using a handle without an ejector device.

Die mindestens eine Ausstoßvorrichtung des Innenschubkastens kann vorzugsweise auch optional durch Eindrücken des Innenschubkastens vor der Schließposition in eine Überdrückstellung entriegelt werden. Dadurch hat der Benutzer die Wahlmöglichkeit, den Innenschubkasten über eine Bewegung des Schubkastens oder durch ein Eindrücken des Innenschubkastens zu öffnen.The at least one ejection device of the inner drawer can preferably also optionally be unlocked by pressing the inner drawer into an overpressed position before the closed position. This gives the user the option of opening the inner drawer by moving the drawer or by pressing the inner drawer.

Ein Möbel 1 umfasst einen Möbelkorpus 2, an dem ein Schubkasten 3 verfahrbar gelagert ist. Wie der Figur 2 zu entnehmen ist, befindet sich der Schubkasten 3 unterhalb eines Innenschubkastens 5, wobei eine Frontblende 4 des Schubkastens 3 eine Frontblende 6 des Innenschubkastens 5 verdeckt, so dass diese in der Schließposition (Figur 1) nicht sichtbar ist.A piece of furniture 1 comprises a furniture body 2 on which a drawer 3 is movably mounted. Again Figure 2 can be seen, the drawer 3 is located below an inner drawer 5, whereby a front panel 4 of the drawer 3 covers a front panel 6 of the inner drawer 5 so that it is in the closed position ( Figure 1 ) is not visible.

Wie in Figur 3 gezeigt ist, werden sowohl der Schubkasten 3 als auch der Innenschubkasten 5 über Auszugsführungen 8 verfahrbar an dem Möbelkorpus 2 gehalten, wobei jede Auszugsführung 8 eine stationäre Führungsschiene 9, eine Mittelschiene 10 und eine Laufschiene 11 aufweist, wobei auch Auszugsführungen 8 mit nur zwei Scheinen oder mehr als drei Schienen eingesetzt werden können. Jede Auszugsführung ist über einen Haltewinkel 7 an einer Seitenwand des Möbelkorpus 2 montiert.As in Figure 3 is shown, both the drawer 3 and the inner drawer 5 are movably held on the furniture body 2 via pull-out guides 8, each pull-out guide 8 having a stationary guide rail 9, a central rail 10 and a running rail 11, with pull-out guides 8 with only two rails or more than three rails can be used. Each pull-out guide is mounted on a side wall of the furniture body 2 via a bracket 7.

An jeder Auszugsführung 8 ist ein Halter 30 fixiert, an dem eine Ausstoßvorrichtung 12 gehalten ist. An jeder Ausstoßvorrichtung 12 ist ein Antriebselement 13 linear geführt, das über einen Kraftspeicher in Öffnungsrichtung gespannt ist, um den Schubkasten 3 oder den Innenschubkasten 5 auszuwerfen. Die Ausstoßvorrichtungen 12 können dabei so ausgebildet sein, wie dies in der DE 10 2016 113 044 offenbart ist.A holder 30 on which an ejector device 12 is held is fixed to each pull-out guide 8. A drive element 13 is linearly guided on each ejection device 12 and is tensioned in the opening direction via an energy storage device in order to eject the drawer 3 or the inner drawer 5. The ejection devices 12 can be designed as shown in FIG DE 10 2016 113 044 is revealed.

Die zwei Ausstoßvorrichtungen 12 für den Innenschubkasten und die zwei Ausstoßvorrichtungen 13 für den Schubkasten 3 sind jeweils über Synchronisationsmittel 14 miteinander gekoppelt, die als drehbare Stange ausgebildet sind und dafür sorgen, dass bei der Entriegelung einer Verriegelungseinrichtung einer Ausstoßvorrichtung 12 auch die Verriegelungseinrichtung der anderen Ausstoßvorrichtung 12 entriegelt wird, so dass beide Ausstoßvorrichtungen 12 gleichzeitig den Schubkasten 3 oder den Innenschubkasten 5 auswerfen.The two ejection devices 12 for the inner drawer and the two ejection devices 13 for the drawer 3 are each coupled to one another via synchronization means 14, which are designed as a rotatable rod and ensure that when one locking device of an ejection device 12 is unlocked, the locking device of the other ejection device 12 is unlocked so that both ejectors 12 eject the drawer 3 or the inner drawer 5 at the same time.

In den Figuren 4A und 4B ist der Innenschubkasten 5 in einer Schließposition gezeigt, und der Schubkasten 3 wurde weggelassen, so dass die Auszugsführung 8 für den Schubkasten 3 sichtbar ist. An der Laufschiene 11 der Auszugsführung 8 für den Schubkasten ist an einer Außenseite ein Aktivator 16 in Form eines Vorsprunges vorgesehen, der bei Erreichen einer vorbestimmten Öffnungsposition des Schubkastens 3 auf einen verschwenkbaren Hebel 17 wirkt und diesen verschwenkt. Der Hebel 17 ist dabei an einem Gehäuse 18 drehbar gelagert, das an einer Seitenwand des Möbelkorpus 2 fixiert ist.In the Figures 4A and 4B the inner drawer 5 is shown in a closed position, and the drawer 3 has been omitted so that the pull-out guide 8 for the drawer 3 is visible. On the running rail 11 of the pull-out guide 8 for the drawer, an activator 16 in the form of a projection is provided on an outside which, when the drawer 3 reaches a predetermined opening position, acts on a pivotable lever 17 and pivots it. The lever 17 is rotatably mounted on a housing 18 which is fixed on a side wall of the furniture body 2.

Wie den Figuren 5A und 5B entnehmbar ist, wird durch den Hebel 17 eine vertikale Stange 19 gedreht, die mit dem Hebel 17 gekoppelt ist. Die vertikale Stange 19 ist über eine erste Umlenkvorrichtung 20 mit einer horizontalen Stange 25 verbunden. Die Umlenkvorrichtung 20 umfasst ein topfförmiges Gehäuse, an dem ein erstes Lager 21 für die vertikale Stange 19 und ein zweites Lager 22 für die horizontale Stange 25 ausgebildet ist. An einer Endseite der vertikalen Stange 19 sind Zähne 23 und an einer Endseite der horizontalen Stange 25 sind Zähne 24 ausgeformt, die miteinander in Eingriff stehen, so dass durch ein Drehen der vertikalen Stange 19 auch die horizontale Stange 25 gedreht wird. Alternativ kann anstelle der Zahnräder auch eine andere Mechanik wie z.B. ein Kreuzgelenk vorgesehen sein.Like that Figures 5A and 5B can be removed, a vertical rod 19, which is coupled to the lever 17, is rotated by the lever 17. The vertical rod 19 is connected to a horizontal rod 25 via a first deflection device 20. The deflection device 20 comprises a pot-shaped housing on which a first bearing 21 for the vertical rod 19 and a second bearing 22 for the horizontal rod 25 are formed. Teeth 23 are formed on one end side of the vertical rod 19 and teeth 24 are formed on one end side of the horizontal rod 25, which mesh with each other so that rotating the vertical rod 19 also rotates the horizontal rod 25. Alternatively, a different mechanism, such as a universal joint, can be provided instead of the gears.

Die horizontale Stange 25 ist über eine weitere Umlenkvorrichtung 26 mit einer Betätigungswelle 29 gekoppelt. Die Umlenkvorrichtung 26 umfasst ebenfalls ein topfförmiges Gehäuse, an dem Lager 27 und 28 für die Stange 25 und die Betätigungswelle 29 vorgesehen sind. Die horizontale Stange 25 umfasst im Bereich der Umlenkvorrichtung 26 endseitig Zähne 35, die mit Zähnen 31 der Betätigungswelle 29 in Eingriff stehen. Die Betätigungswelle 29 ist über zwei Zahnräder 32 und 34 mit einer Entriegelungswelle 33 gekoppelt, die wiederum drehfest mit den Synchronisationsmitteln 14 verbunden ist. Durch die Entriegelungswelle 33 kann über mindestens einen radial hervorstehenden Vorsprung eine Entriegelung einer Verriegelungseinrichtung der Ausstoßvorrichtung 12 bewirkt werden, um das vorgespannte Antriebselement entlang einer Führung in Öffnungsrichtung zu bewegen. Das Antriebselement 13 ist mit einem Kopplungselement am Innenschubkasten 5 oder an der Laufschiene der Auszugsführung 8 für den Innenschubkasten 3 für den Auswurfbereich koppelbar, und beabstandet von dem Auswurfbereich findet eine Entkopplung statt. Zum Laden eines Kraftspeichers der Ausstoßvorrichtung 12 wird über das Stützelement das Antriebselement 13 in Schließrichtung bewegt, wobei das Laden des Kraftspeichers versetzt zu der Auswerfstrecke durch die Ausstoßvorrichtung 12 angeordnet ist, also beabstandet von der Schließposition durchgeführt wird. Dadurch kann über eine Bewegung des Antriebselementes 13 in Schließrichtung zunächst der Kraftspeicher geladen und verrastet werden, bevor ein Selbsteinzug 40 an der Auszugsführung 8 den Innenschubkasten 3 in Schließrichtung zieht und in einer Schließposition hält. Der Selbsteinzug 40 kann zudem einen Dämpfer aufweisen, um eine Schließbewegung des Innenschubkastens 5 abzubremsen.The horizontal rod 25 is coupled to an actuating shaft 29 via a further deflection device 26. The deflecting device 26 also comprises a pot-shaped housing on which bearings 27 and 28 for the rod 25 and the actuating shaft 29 are provided. The horizontal rod 25 has teeth 35 at the end in the region of the deflection device 26, which teeth mesh with teeth 31 of the actuating shaft 29. The actuating shaft 29 is coupled via two gear wheels 32 and 34 to an unlocking shaft 33, which in turn is connected to the synchronization means 14 in a rotationally fixed manner. The unlocking shaft 33 can unlock a locking device of the ejection device 12 via at least one radially protruding projection in order to move the pretensioned drive element along a guide in the opening direction. The drive element 13 can be coupled to a coupling element on the inner drawer 5 or on the running rail of the pull-out guide 8 for the inner drawer 3 for the ejection area, and decoupling takes place at a distance from the ejection area. To load an energy accumulator of the ejector device 12, the drive element 13 is moved in the closing direction via the support element, the loading of the energy accumulator being arranged offset to the ejection path through the ejector device 12, i.e. being carried out at a distance from the closed position. As a result, by moving the drive element 13 in the closing direction, the energy storage device can first be loaded and latched before a Self-closing 40 on the pull-out guide 8 pulls the inner drawer 3 in the closing direction and holds it in a closed position. The self-closing mechanism 40 can also have a damper in order to brake a closing movement of the inner drawer 5.

In den Figuren 6A und 6B sind die Ausstoßvorrichtungen 12 und die Auszugsführung 8 für den Schubkasten 3 und den Innenschubkasten 5 gezeigt. Der verschwenkbare Hebel 17 ist durch einen Kraftspeicher wieder in eine Ausgangsposition gedrückt worden und kann beim Verfahren der Laufschiene mit dem Aktivator 16 überfahren werden, ohne dass die Verriegelungseinrichtung entriegelt wird, beispielsweise weil ein Freilauf vorgesehen ist.In the Figures 6A and 6B the ejectors 12 and the pull-out guide 8 for the drawer 3 and the inner drawer 5 are shown. The pivotable lever 17 has been pushed back into a starting position by an energy store and can be overridden by the activator 16 when the running rail is moved without the locking device being unlocked, for example because a freewheel is provided.

Das Öffnen des Innenschubkastens kann durch ein Öffnen des Schubkastens bewirkt werden, wobei der Schubkasten in dem dargestellten Ausführungsbeispiel durch Ausstoßvorrichtungen 12 auswerfbar ist, wenn die Frontblende 4 aus der Schließposition in eine Überdrückstellung eingedrückt wird, um die beiden Ausstoßvorrichtungen 12 für den Schubkasten 3 zu entriegeln. Alternativ kann der Schubkasten 3 an der Frontblende 4 auch mit einem Griffelement versehen werden, und der Schubkasten 3 kann dann über das Griffelement in Öffnungsrichtung bewegt werden. Unabhängig davon, wie der Schubkasten 3 in Öffnungsrichtung bewegt wird, kann über eine Öffnungsbewegung des Schubkastens eine Entriegelung einer oder beider Ausstoßvorrichtungen 12 für den Innenschubkasten 5 erfolgen, wobei der Aktivator 16 die Hebel 17 der Betätigungsmittel verschwenkt, wodurch eine Drehbewegung der vertikalen Stangen 19, der horizontalen Stangen 15, der Betätigungswellen 29 und damit auch der Entriegelungswelle 33 erfolgt. Diese Getriebekette bewirkt eine Entriegelung der Verriegelungseinrichtung der beiden Ausstoßvorrichtungen 12, die zusätzlich über die Synchronisationsmittel 14 synchronisiert sind, um den Innenschubkasten 5 bei Erreichen einer vorbestimmten Position des Schubkastens 3 auszuwerfen. Zum Auswerfen verfahren die beiden Antriebselemente 13 der Ausstoßvorrichtung 12 in Öffnungsrichtung.The inner drawer can be opened by opening the drawer, the drawer in the illustrated embodiment being ejectable by ejectors 12 when the front panel 4 is pushed out of the closed position into an overpressed position in order to unlock the two ejectors 12 for the drawer 3 . Alternatively, the drawer 3 on the front panel 4 can also be provided with a handle element, and the drawer 3 can then be moved in the opening direction via the handle element. Regardless of how the drawer 3 is moved in the opening direction, one or both ejection devices 12 for the inner drawer 5 can be unlocked via an opening movement of the drawer, the activator 16 pivoting the levers 17 of the actuating means, whereby a rotary movement of the vertical rods 19, the horizontal rods 15, the actuating shafts 29 and thus also the unlocking shaft 33 takes place. This gear chain unlocks the locking device of the two ejection devices 12, which are additionally synchronized via the synchronization means 14 in order to eject the inner drawer 5 when the drawer 3 reaches a predetermined position. For ejection, the two drive elements 13 of the ejection device 12 move in the opening direction.

Die Position, an der der Aktivator 16 auf die Betätigungsmittel zum Auswerfen des Innenschubkastens 5 wirkt, kann vorzugsweise in einem Öffnungsbereich angeordnet sein, an dem der Schubkasten mindestens 50 % der maximalen Wegstrecke zur maximalen Öffnungsposition zurückgelegt hat, vorzugsweise mindestens 70 %. Zudem ist es möglich, dass der Aktivator 16 mit Verstellmitteln versehen ist, so dass die Position eingestellt werden kann, an der der Schubkasten über den Aktivator 16 eine Entriegelung der Ausstoßvorrichtung 12 für den Innenschubkasten 5 bewirkt.The position at which the activator 16 acts on the actuating means for ejecting the inner drawer 5 can preferably be arranged in an opening area in which the drawer has covered at least 50% of the maximum distance to the maximum opening position, preferably at least 70%. In addition, it is possible that the activator 16 is provided with adjusting means so that the position can be set at which the Drawer causes the ejector 12 for the inner drawer 5 to be unlocked via the activator 16.

In dem dargestellten Ausführungsbeispiel ist die Ausstoßvorrichtung über ein Getriebe aus drehbaren Stangen mit dem Aktivator gekoppelt. Das Getriebe kann auch durch andere Elemente gebildet sein, beispielsweise einen Bowdenzug oder andere Getriebeelemente. Zudem ist es möglich, statt der stationären Ausstoßvorrichtungen 12 auch Ausstoßvorrichtungen vorzusehen, die am Schubkasten oder der Laufschiene montiert sind, so dass das Antriebselement 13 der Ausstoßvorrichtung 12 mit einem stationären Halter zusammenwirkt, um den Innenschubkasten und/oder den Schubkasten auszuwerfen.In the exemplary embodiment shown, the ejection device is coupled to the activator via a transmission made up of rotatable rods. The transmission can also be formed by other elements, for example a Bowden cable or other transmission elements. In addition, instead of the stationary ejector devices 12, it is also possible to provide ejector devices that are mounted on the drawer or the running rail so that the drive element 13 of the ejector device 12 cooperates with a stationary holder in order to eject the inner drawer and / or the drawer.
