Description

Die Erfindung betrifft eine Vorrichtung zur lösbaren Verbindung eines in einem Möbelkorpus über eine Führungseinheit beweglich geführten Möbelauszugs mit der Führungseinheit, mit einem Vorrichtungsgehäuse, an dem ein Stellelement angeformt und an diesem über wenigstens ein Festkörpergelenk derart schwenkbeweglich gelagert ist, dass bei Betätigung des Stellelements die Verbindung zwischen dem Möbelauszug und der Führungseinheit lösbar ist.The invention relates to a device for releasably connecting a movable in a furniture body via a guide unit furniture drawer with the guide unit, with a device housing on which a control element is formed and mounted on this at least one solid-state pivot so pivotally that upon actuation of the actuating element, the compound between the furniture drawer and the guide unit is solvable.

Eine Vorrichtung dieser Art ist beispielsweise aus der EP 0 695 523 B1 bekannt. Derartige Vorrichtungen dienen zum Kuppeln der Führungseinheit mit einem Möbelauszug, so dass der Möbelauszug, beispielsweise Schublade, bei Bedarf von der Führungseinheit getrennt werden kann. Dadurch lässt er sich für sich aus dem Möbelkorpus herausnehmen, wodurch es möglich ist, die Führungseinheit bleibend im Korpus zu montieren. Die Vorrichtung aus dem vorerwähnten Stand der Technik ist als einteiliges Formstück aus biegbarem Kunststoff hergestellt. Dabei ist ein Stellelement an einen Basisabschnitt des Formstücks angespritzt. Das Stellelement umfasst einen Handgriff und einen einstückig mit dem Handgriff verbundenen Rastabschnitt mit einem Rasthaken. Durch Betätigung des Handgriffs lässt sich das Stellelement, das über ein Festkörpergelenk mit dem Basisabschnitt des Formstücks verbunden ist, verschwenken, womit der Rasthaken aus einem komplementären Rastabschnitt an der Führungseinheit ausrastet, so dass der Möbelauszug von der Führungseinheit getrennt werden kann.A device of this kind is for example from the EP 0 695 523 B1 known. Such devices are used for coupling the guide unit with a furniture extract, so that the furniture drawer, such as drawer, can be separated if necessary from the guide unit. As a result, he can be taken out of the furniture body, which makes it possible to permanently mount the guide unit in the carcass. The device of the aforementioned prior art is made as a one-piece molding of flexible plastic. In this case, an actuating element is molded onto a base portion of the molding. The adjusting element comprises a handle and an integrally connected to the handle latching portion with a latching hook. By operating the handle can be the actuator, which has a solid-state joint is connected to the base portion of the fitting, pivot, whereby the latching hook from a complementary latching portion on the guide unit disengages, so that the furniture drawer can be separated from the guide unit.

Auf einen Möbelauszug wirken insbesondere beim Öffnen und Schließen nicht unerhebliche Kräfte ein, vor allem wenn der Möbelauszug relativ schwer beladen ist. Insbesondere auf am Möbelauszug angeordnete Peripherieteile, wie zum Beispiel die vorerwähnte Vorrichtung, können hohen Belastungen ausgesetzt sein. Zum Beispiel besteht bei Stellelementen aus Kunststoff die Gefahr von Materialbruch. Dies wird beispielsweise in einem dynamischen Anschlagtest "Öffnen mit Überlast" simuliert. Bei diesem Test wird der Möbelauszug mit voller Kraft aus der geschlossenen Position in eine geöffnete Position gebracht, um die Beständigkeit von einzelnen Bauteilen zu überprüfen. Dieser dynamische Test ist für das Material sehr stark belastend, so dass es durch Spannungsspitzen immer wieder zu Materialbruch kommt.On a furniture extract act especially when opening and closing not inconsiderable forces, especially if the furniture drawer is relatively heavily loaded. In particular arranged on the furniture drawer peripheral parts, such as the aforementioned device, can be exposed to high loads. For example, with plastic actuators there is a risk of material breakage. This is simulated, for example, in a dynamic stop test "opening with overload". In this test, the furniture drawer is moved full force from the closed position to an open position to check the resistance of individual components. This dynamic test is very stressful for the material, so that there are always material breaks due to voltage peaks.

Aufgabe der Erfindung ist es, eine Vorrichtung der eingangs erwähnten Art zu schaffen, deren Komponenten trotz hoher Belastung eine hohe Lebensdauer besitzen.The object of the invention is to provide a device of the type mentioned, whose components have high durability despite high load.

Diese Aufgabe wird durch eine Vorrichtung mit den Merkmalen des unabhängigen Anspruchs 1 gelöst. Weiterbildungen der Erfindung sind in den Unteransprüchen dargestellt.This object is achieved by a device having the features of independent claim 1. Further developments of the invention are shown in the subclaims.

Die erfindungsgemäße Vorrichtung zeichnet sich dadurch aus, dass beabstandet vom Festkörpergelenk bzw. Filmscharnier angeordnete Abstützmittel vorhanden sind, mit denen das Stellelement unter Verhinderung einer Relativbewegung zwischen sich und dem Vorrichtungsgehäuse abstützbar ist.The inventive device is characterized in that spaced from the solid-state hinge or film hinge arranged supporting means are provided, with which the actuating element can be supported while preventing relative movement between itself and the device housing.

Die Abstützmittel bewirken eine Abstützung des Stellelements, wodurch das Stellelement selbst bei starken Belastungen nur minimal verformt wird. Der dynamische Anschlagtest "Öffnen mit Überlast" kann mit der erfindungsgemäßen Vorrichtung durchgeführt werden, ohne dass es zu Materialbruch kommt. Insgesamt besitzt die Vorrichtung eine hohe Lebensdauer, so dass ein Austausch solcher Vorrichtungen im Falle einer Beschädigung sehr selten oder praktisch nicht notwendig ist. Dies wirkt sich insgesamt kostenmindernd aus. Selbstverständlich sind die Abstützmittel derart angeordnet, dass die Betätigung des Stellelements, das heißt der Lösevorgang des Möbelauszugs von der Führungseinheit, nicht behindert wird.The support means cause a support of the adjusting element, whereby the adjusting element is only minimally deformed even under heavy loads. The dynamic stop test "opening with overload" can be carried out with the device according to the invention, without resulting in material fracture. Overall, the device has a long life, so that replacement of such devices in the event of damage is very rare or practically unnecessary. This has an overall cost-reducing effect. Of course, the support means are arranged such that the actuation of the actuating element, that is, the release operation of the furniture drawer of the guide unit, is not hindered.

Bei einer Weiterbildung der Erfindung sind die Abstützmittel derart ausgebildet, dass eine Abstützung des Stellelements sowohl in X-, Y- als auch in Z-Raumrichtung eines durch X-, Y- und Z-Koordinaten aufgespannten kartesischen Koordinatensystems möglich ist. Die Abstützmittel können also für eine zuverlässige Abstützung in allen drei Raumrichtungen sorgen, so dass die Richtung der Krafteinwirkung keine Rolle spielt.In a further development of the invention, the support means are designed such that a support of the actuating element in both the X, Y and in the Z spatial direction of a spanned by X, Y and Z coordinates Cartesian coordinate system is possible. The support means can thus provide a reliable support in all three spatial directions, so that the direction of the force does not matter.

Bei einer Weiterbildung der Erfindung weisen die Abstützmittel komplementäre Abstützflächen am Vorrichtungsgehäuse einerseits und Stellelement andererseits auf.In a further development of the invention, the support means complementary support surfaces on the device housing on the one hand and actuator on the other.

Die Abstützflächen können von von der Peripherie des Vorrichtungsgehäuses und/oder von von der Peripherie des Stellelements vorspringenden Abstützvorsprüngen gebildet sein. Zweckmäßigerweise werden die Abstützvorsprünge bei der Herstellung von Gehäuse und Stellelement gleich mitangeformt. Alternativ wäre es möglich, die zueinander komplementären Abstützflächen an Vorrichtungsgehäuse und Stellelement so zu wählen, dass keine gesonderten Vorsprünge ausgebildet sind, sondern ohnehin bei der Herstellung von Gehäuse und Stellelement vorhandene Flächen genutzt werden, die dann derart aufeinander abzustimmen sind, dass sie einerseits zueinander komplementär sind und andererseits dicht beieinander liegen oder in Kontakt zueinander stehen, so dass unter Krafteinwirkung eine zuverlässige Abstützwirkung erzielbar ist.The support surfaces may be formed by supporting projections protruding from the periphery of the device housing and / or protruding from the periphery of the actuator. Conveniently, the support projections are mitangeformt same in the production of housing and actuator. Alternatively, it would be possible to choose the mutually complementary support surfaces on the device housing and actuator so that no separate projections are formed, but anyway in the production of housing and actuator existing surfaces are used, which are then coordinated so that they are both complementary to each other and on the other hand are close to each other or in contact with each other, so that under force a reliable support effect can be achieved.

Bei einer Weiterbildung der Erfindung ist das Stellelement hebelartig ausgebildet, mit einem manuell betätigbaren Betätigungsabschnitt, der diesseits des Festkörpergelenks und einem Eingriffsabschnitt zum Eingriff in die komplementären Eingriffsmittel an der Führungseinheit, der jenseits des Festkörpergelenks angeordnet ist.In a further development of the invention, the actuating element is designed like a lever, with a manually operable actuating portion, which is arranged on this side of the solid-body joint and an engagement portion for engagement in the complementary engagement means on the guide unit, which is beyond the solid-state joint.

Um einen guten Halt des Eingriffsabschnitts auf Seiten des Stellelements und der komplementären Eingriffsmittel im Eingriff zu gewährleisten, wobei gleichzeitig ein einfaches Lösen des Eingriffsabschnitts von den Eingriffsmitteln möglich sein soll, weisen Eingriffsabschnitt und Eingriffsmittel Rastmittel auf. Das Lösen des Möbelauszugs von der Führungseinheit erfolgt also in einfacher Weise durch Ausrasten der am Eingriffsabschnitt ausgebildeten Rastmittel von den komplementären Rastmitteln der Führungseinheit. Zweckmäßigerweise werden die Rastmittel von Rastzähnen gebildet.In order to ensure a good grip of the engaging portion on the side of the adjusting element and the complementary engagement means in engagement, at the same time a simple release of the engagement portion of the engagement means to be possible, engaging portion and engaging means locking means. The release of the furniture drawer of the guide unit thus takes place in a simple manner by disengaging the locking means formed on the engagement portion of the complementary locking means of the guide unit. Advantageously, the locking means are formed by ratchet teeth.

Bei einer Weiterbildung der Erfindung ist eine Verstelleinheit zur Höhenverstellung des Möbelauszugs in Bezug zur Führungseinheit vorgesehen. Damit lässt sich das Fugenbild zwischen dem Möbelauszug und dem ihn umgebenden Möbelkorpus in Höhenrichtung einstellen.In a further development of the invention, an adjusting unit for height adjustment of the furniture drawer is provided in relation to the guide unit. This allows the joint image between the furniture drawer and the surrounding furniture body in the height direction set.

Besonders bevorzugt weist die Verstelleinheit ein in den Zwischenraum zwischen der Unterseite des Möbelauszugs und der Führungseinheit hineinragendes keilartiges Verstellglied auf, bei dessen Verstellbewegung ein Anheben oder Absenken des Möbelauszugs in Bezug zur Führungseinheit stattfindet.Particularly preferably, the adjusting unit has a wedge-like adjusting element projecting into the intermediate space between the underside of the furniture drawer and the guide unit, in the adjusting movement takes place raising or lowering of the furniture drawer in relation to the guide unit.

In besonders bevorzugter Weise ist das Verstellglied mittels eines einen Lagerzapfen aufweisenden Schwenklagers schwenkbeweglich am Vorrichtungsgehäuse gelagert. Die Höhenverstellung wird also durch ein Verschwenken des Verstellglieds in die eine oder andere Richtung bewirkt.In a particularly preferred manner, the adjusting member is pivotally mounted on the device housing by means of a pivot bearing having a bearing journal. The height adjustment is thus effected by pivoting the adjusting in one or the other direction.

In besonders bevorzugter Weise ist der Lagerzapfen Bestandteil der Abstützmittel für das Stellelement. Der Lagerzapfen ist also multifunktional und hat neben seiner Funktion als Teil des Schwenklagers noch die Funktion als Abstützmittel.In a particularly preferred manner, the journal is part of the support means for the actuator. The bearing pin is therefore multifunctional and, in addition to its function as part of the pivot bearing still has the function as a support means.

Bei einer Weiterbildung der Erfindung bestehen Vorrichtungsgehäuse und Stellelement aus Kunststoffmaterial. Insbesondere wird für Vorrichtungsgehäuse und Stellelement dasselbe Kunststoffmaterial verwendet.In a further development of the invention device housing and actuator made of plastic material. In particular, the same plastic material is used for device housing and actuator.

In besonders bevorzugter Weise sind Vorrichtungsgehäuse und Stellelement Kunststoffspritzgießteile, wobei das Stellelement bei der Herstellung gleich an das Vorrichtungsgehäuse anzuspritzen ist. Es wäre auch denkbar, Vorrichtungsgehäuse und Stellelement durch ein Zwei-Komponenten-Spritzgießverfahren herzustellen, wobei Gehäuse und Stellelement dann aus unterschiedlichem Kunststoffmaterial bestehen würden.In a particularly preferred manner, the device housing and actuating element are plastic injection-molded parts, wherein the actuating element is to be sprayed onto the device housing in the same way during production. It would also be conceivable to produce device housing and actuator by a two-component injection molding process, wherein housing and actuator would then consist of different plastic material.

Die Erfindung umfasst ferner noch ein Möbel, mit einem relativ zu einem Möbelkorpus bewegbaren, über eine Führungseinheit geführten Möbelauszug, der durch eine Vorrichtung nach einem der Ansprüche 1 bis 12 gekennzeichnet ist.The invention further comprises a piece of furniture, with a relative to a furniture body movable, guided over a guide unit furniture drawer, which is characterized by a device according to one of claims 1 to 12.

Conveniently, the actuator 17 is made of the same plastic material, whereby the manufacturing costs, since it can be produced by one-component injection molding, are low.

Das Stellelement 17 ist über das Festkörpergelenk 18 schwenkbeweglich an dem Lagerabschnitt 16 gelagert. Das Stellelement 17 besitzt einen manuell betätigbaren Betätigungsabschnitt 19, der handgriffartig ausgestaltet ist. Der Betätigungsabschnitt 19 liegt auf der einen Seite des Festkörpergelenks, wobei auf der anderen Seite ein Eingriffsabschnitt 20 vorgesehen ist, der zum Eingriff in komplementäre Eingriffsmittel (nicht dargestellt) an der Führungseinheit vorgesehen ist.The actuator 17 is pivotally mounted on the bearing portion 16 via the solid-state joint 18. The actuator 17 has a manually operable operating portion 19 which is designed like a handle. The operating portion 19 is located on one side of the solid-state hinge, wherein on the other side an engagement portion 20 is provided is, which is provided for engagement in complementary engagement means (not shown) on the guide unit.

Wie insbesondere in Figur 1 dargestellt, ist der handgriffartige Betätigungsabschnitt 19 keilartig ausgestaltet, wobei an der Außenseite des Betätigungsabschnitts 19 eine gegebenenfalls gekrümmt verlaufende Betätigungsfläche 21 vorgesehen ist, zum Greifen Mittels Finger des Benutzers. Wie insbesondere in Figur 3 dargestellt, ist der Eingriffsabschnitt 20 auf der anderen Seite des Festkörpergelenks 18 mit Rastmitteln in Form von Rastzähnen 22 versehen. Die Rastzähne 22 am Eingriffsabschnitt 20 sind in der in Figur 1 dargestellten Stellung des Stellelements 17 mit nicht dargestellten komplementären Rastzähnen an der Führungseinheit verrastet, wodurch die Schublade mit der Führungseinheit gekoppelt ist. Durch über Finger des Benutzers ausgeübten Druck auf die Betätigungsfläche 21 lässt sich das Stellelement 17 in Uhrzeigerrichtung um das Festkörpergelenk 18 verschwenken, wobei der Eingriffsabschnitt 20 mit den Rastzähnen 22 in GegenUhrzeigerrichtung in Richtung auf den Lagerabschnitt 16 des Vorrichtungsgehäuses 12 zu schwenkt, wodurch Rastzähne am Stellelement 17 aus den komplementären Rastzähnen an der Führungseinheit ausrasten.As in particular in FIG. 1 illustrated, the handle-like actuating portion 19 is wedge-shaped, wherein on the outside of the actuating portion 19 an optionally curved extending actuating surface 21 is provided, for gripping by the user's finger. As in particular in FIG. 3 shown, the engaging portion 20 is provided on the other side of the solid-state hinge 18 with locking means in the form of ratchet teeth 22. The ratchet teeth 22 on the engagement portion 20 are in the in FIG. 1 shown position of the actuating element 17 is locked with complementary detent teeth, not shown, on the guide unit, whereby the drawer is coupled to the guide unit. By exerted on the user's finger pressure on the actuating surface 21, the actuator 17 can pivot in the clockwise direction around the solid-state joint 18, wherein the engagement portion 20 with the ratchet teeth 22 in the counterclockwise direction in the direction of the bearing portion 16 of the device housing 12 to pivot, thereby locking teeth on the actuator 17 disengage from the complementary locking teeth on the guide unit.

Wie insbesondere in Figur 3 zu erkennen, ist am Vorrichtungsgehäuse 12 eine Schwenkausnehmung 23 ausgeformt, die das Verschwenken des Eingriffsabschnitts 20 mit den Rastzähnen 22 um ein gewisses Maß in Richtung zum Lagerabschnitt 16 ermöglicht. Die Vorrichtung 11 umfasst ferner Abstützmittel 24, die beabstandet vom Festkörpergelenk angeordnet sind. Die Abstützmittel 24 sind derart ausgebildet, dass eine Abstützung des Stellelements 17 sowohl in X-, Y- als auch in Z-Raumrichtung eines durch X-, Y- und Z-Koordinaten aufgespannten kartesischen Koordinatensystems möglich ist. Hierzu sind zueinander komplementäre Abstützflächen 25a, 25b, 26a, 26b, 27a, 27b am Vorrichtungsgehäuse 11 einerseits und Stellelement 17 andererseits vorgesehen, die eine Abstützung des Stellelements gegenüber in X-, Y- und Z-Raumrichtung wirkenden Kräften ermöglichen. Die Abstützflächen 25a-27b sind an Abstützvorsprüngen ausgebildet, die von der Peripherie des Stellelements 17 und von der Peripherie des Vorrichtungsgehäuses 12 vorspringen. Zu den Abstützvorsprüngen zählen X-Abstützvorsprünge 28a, 28b, an denen sich die Abstützflächen 25a, 25b gegen in X-Richtung wirkende Kräfte befinden. Der X-Abstützvorsprung 28a am Vorrichtungsgehäuse wird von einem Lagerzapfen 29 eines nachfolgend noch näher beschriebenen Verstellglieds 30 einer Verstelleinheit zur Höhenverstellung des Möbelauszugs gebildet. Die dazugehörige Abstützfläche 25a befindet sich an der Umfangsfläche des Lagerzapfens 29. Komplementär dazu ist der X-Abstützvorsprung 28b des Stellelements an der Unterseite des Stellelements 17 von dieser abragend angeordnet. Die dazugehörige Abstützfläche 25b ist die der Abstützfläche 25a am Lagerzapfen 29 zugewandte Fläche des X-Abstützvorsprungs 28b.As in particular in FIG. 3 can be seen, a pivot recess 23 is formed on the device housing 12, which allows the pivoting of the engagement portion 20 with the ratchet teeth 22 by a certain amount in the direction of the bearing portion 16. The device 11 further comprises support means 24 which are spaced from the solid-state joint. The support means 24 are designed such that a support of the actuating element 17 in both the X, Y and in the Z-space direction of a spanned by X, Y and Z coordinates Cartesian coordinate system is possible. These are mutually complementary support surfaces 25a, 25b, 26a, 26b, 27a, 27b provided on the device housing 11 on the one hand and actuator 17 on the other hand, which allow a support of the actuating element with respect to forces acting in X-, Y- and Z-space direction. The support surfaces 25 a - 27 b are formed on support projections projecting from the periphery of the actuator 17 and from the periphery of the device housing 12. The support projections include X-support projections 28a, 28b, on which the support surfaces 25a, 25b are against forces acting in the X-direction. The X-support projection 28a on the device housing is formed by a bearing journal 29 of an adjustment element 30, which will be described in more detail below, of an adjustment unit for adjusting the height of the furniture drawer. The associated support surface 25a is located on the peripheral surface of the bearing pin 29. Complementarily, the X-support projection 28b of the adjusting element on the underside of the adjusting element 17 is arranged projecting from this. The associated support surface 25b is the surface of the X-support projection 28b facing the support surface 25a on the bearing journal 29.

Die Y-Abstützvorsprünge 31a, 31b werden auf Seiten des Vorrichtungsgehäuses 12 durch einen in X-Richtung verlaufenden, eine Begrenzung der Schwenkausnehmung 23 bildenden Stegabschnitt gebildet, während der komplementär dazugehörende Y-Abstützvorsprung 31b am Stellelement 17 durch eine nasenartige, ebenfalls in X-Richtung verlaufende Verlängerung der Stirnseite des Eingriffsabschnitts 20 gebildet ist. Die dazugehörigen Abstützflächen 26a, 26b werden durch einander zugewandte Innenflächen der Abstützvorsprünge 31a, 31b gebildet. Wie insbesondere in Figur 3 dargestellt, ist zwischen diesen beiden Abstützflächen 26a, 26b nur ein sehr kleiner oder gar kein Abstand (die beiden Abstützflächen könnten auch in Berührkontakt zueinander stehen), so dass bei Auftreten von Kräften, die in Y-Richtung wirken, beide Abstützflächen 26a, 26b durch Kontakt zueinander eine Relativbewegung zwischen Stellelement 17 und Vorrichtungsgehäuse 12 in Y-Richtung verhindern.The Y-supporting projections 31a, 31b are formed on the side of the device housing 12 by a web portion extending in the X-direction, forming a boundary of the pivoting recess 23, while the complementarily associated Y-supporting projection 31b on the adjusting element 17 by a nose-like, also in the X direction extending extension of the end face of the engagement portion 20 is formed. The associated support surfaces 26a, 26b are formed by mutually facing inner surfaces of the support projections 31a, 31b. As in particular in FIG. 3 is shown, between these two support surfaces 26a, 26b only a very small or no distance (the two support surfaces could also be in touching contact each other), so that when they occur of forces acting in the Y direction, both support surfaces 26a, 26b prevent relative movement between actuator 17 and device housing 12 in the Y direction by contact with each other.

Die Z-Abstützvorsprünge 32a, 32b sind insbesondere in Figur 2 zu erkennen. Der Z-Abstützvorsprung 32a am Vorrichtungsgehäuse wird dabei durch denselben Stegabschnitt gebildet, der zuvor bereits als Y-Abstützvorsprung 31a beschrieben wurde. Dabei ist die Abstützfläche 27a an der Unterseite dieses Z-Abstützvorsprungs 32a angeordnet. Der Z-Abstützvorsprung 32b am Stellelement 17 wird durch eine weitere nasenartige Verlängerung des Eingriffsabschnitts 20 des Stellelements 17 gebildet. Die Abstützfläche 27b befindet sich dabei an der Oberseite dieses Z-Abstützvorsprungs 32b.The Z-supporting projections 32a, 32b are particularly in FIG. 2 to recognize. The Z-support projection 32a on the device housing is formed by the same web portion, which has been previously described as Y-support projection 31a. In this case, the support surface 27a is arranged on the underside of this Z-support projection 32a. The Z-supporting projection 32b on the adjusting element 17 is formed by a further nose-like extension of the engaging portion 20 of the adjusting element 17. The support surface 27b is located at the top of this Z-Abstützvorsprungs 32b.

Insgesamt werden die X-, Y- und Z-Abstützvorsprünge durch entsprechende Formgebung der Spritzgießform bei der Herstellung der Vorrichtung 11 gleich mitangeformt.Overall, the X-, Y- and Z-supporting projections are mitge formed by appropriate shaping of the injection mold in the manufacture of the device 11 equal.

Zur Vorrichtung 11 gehört ferner noch eine Verstelleinheit zur Höhenverstellung des Möbelauszugs in Bezug zur Führungseinheit. Die Verstelleinheit besitzt hierzu ein in den Zwischenraum zwischen der Unterseite des Möbelauszugs und der Führungseinheit hineinragendes keilartiges Verstellglied 30, das mittels des Lagerzapfens 29 schwenkbeweglich am Vorrichtungsgehäuse 12 gelagert ist. Beim Verschwenken des Verstellglieds 30 greift ein mehr oder weniger breiter beziehungsweise dicker Bereich eines keilartigen Führungsabschnitts 33 des Verstellglieds in den Spalt zwischen Führungseinheit und Unterseite der Schublade ein, wodurch eine Höhenverstellung der Schublade in Bezug zur Führungseinheit und damit zum Möbelkorpus möglich ist.The device 11 further includes an adjusting unit for adjusting the height of the furniture drawer in relation to the guide unit. For this purpose, the adjusting unit has a wedge-like adjusting element 30 projecting into the intermediate space between the underside of the furniture drawer and the guide unit, which is mounted pivotably on the device housing 12 by means of the bearing pin 29. When pivoting the adjusting member 30 engages a more or less wide or thick area of a wedge-like guide portion 33 of the adjusting member in the gap between the guide unit and the underside of the drawer, whereby a height adjustment of the drawer in relation to the guide unit and thus to the furniture body is possible.
