Description

Die vorliegende Erfindung betrifft eine Ausstoßvorrichtung für ein bewegbares Möbelteil nach dem Oberbegriff des Anspruches 1, und ein Möbel mit mindestens einem Schubkasten.The present invention relates to an ejection device for a movable furniture part according to the preamble of claim 1, and a piece of furniture with at least one drawer.

DE 20 2009 013 733 U1 offenbart eine Vorrichtung zum Öffnen eines Schubkastens, bei dem zwei Auslöseelemente miteinander über eine drehbare Stange gekoppelt sind. DE 20 2009 013 733 U1 discloses a device for opening a drawer, in which two release elements are coupled to one another via a rotatable rod.

In der EP 1 785 063 A1 ist eine Vorrichtung zum Öffnen und Schließen eines bewegbaren Möbelteils offenbart, bei der zwei Verriegelungselemente einer Verriegelungseinheit miteinander über eine Torsionsstange gekoppelt sind.In the EP 1 785 063 A1 discloses a device for opening and closing a movable furniture part, in which two locking elements of a locking unit are coupled to one another via a torsion bar.

Die EP 1 314 842 A1 offenbart eine Vorrichtung zum Öffnen und Schließen eines beweglichen Möbelteils, bei dem zwei Auslöse- und Antriebseinheiten vorgesehen sind, die über ein Gestänge miteinander gekoppelt sind, um bei Entriegelung einer Auslöse- und Antriebseinheit auch die zweite Auslöse- und Antriebseinheit zu entriegeln und ein bewegbares Möbelteil in Öffnungsrichtung zu bewegen. Für die Synchronisierung der Bewegung sind zwei Schwenkhebel vorgesehen, die über ein Gestänge miteinander verbunden sind, so dass der erforderliche Bauraum für die Mittel zur Synchronisierung erheblich ist. Zudem sind eine Vielzahl von Bauteilen vorgesehen, die die Herstellung und Montage aufwändig machen.The EP 1 314 842 A1 discloses a device for opening and closing a movable furniture part, in which two release and drive units are provided, which are coupled to one another via a linkage, in order to also unlock the second release and drive unit and a movable furniture part when a release and drive unit is unlocked to move in the opening direction. To synchronize the movement, two pivot levers are provided which are connected to one another via a linkage, so that the space required for the synchronization means is considerable. In addition, a large number of components are provided which make production and assembly complex.

Die DE 10 2011 001 983 A1 offenbart eine Ausstoßvorrichtung, bei der ein verschwenkbar gelagerter Hebel über eine Feder in Ausstoßrichtung vorgespannt ist und über einen Rastmechanismus bei gespannter Feder verrastbar ist. Die Ausstoßvorrichtung kann über eine Verbindungsstange mit einer weiteren Ausstoßvorrichtung gekoppelt sein, wobei die Verbindungsstange im Bereich der Drehachse der beiden Hebel angeordnet ist. Zwar lässt sich dadurch eine Synchronisierung des Entriegelungsvorganges bewirken, der Platzbedarf im rückwärtigen Bereich des Schubkastens ist allerdings erheblich.The DE 10 2011 001 983 A1 discloses an ejection device in which a pivotably mounted lever is pretensioned in the ejection direction via a spring and can be latched via a latching mechanism when the spring is tensioned. The ejector device can be coupled to a further ejector device via a connecting rod, the connecting rod being arranged in the area of the axis of rotation of the two levers. It is true that this enables the unlocking process to be synchronized, but the space requirement in the rear area of the drawer is considerable.

Für eine kompaktere Bauweise kann bei einer Ausstoßvorrichtung gemäß der DE 10 2012 112 675 A1 an einer Rückwand eines Schubkastens eine Ausstoßvorrichtung mit zwei schwenkbar gelagerten Auswerferhebeln montiert werden, die über einen Rastmechanismus verrastbar sind, wobei ein Entriegelungsvorgang über zwei Stangen und ein Getriebe synchronisiert ist. Die Ausstoßvorrichtung erfordert eine vergleichsweise stabile Rückwand an einem Schubkasten und lässt sich somit nicht für alle Typen von Schubkästen einsetzen.For a more compact design, an ejection device according to FIG DE 10 2012 112 675 A1 an ejector with two pivotably mounted ejector levers can be mounted on a rear wall of a drawer, which can be locked via a latching mechanism, an unlocking process being synchronized via two rods and a gear. The ejector requires a comparatively stable back wall on a drawer and can therefore not be used for all types of drawers.

Es ist daher Aufgabe der vorliegenden Erfindung, eine Ausstoßvorrichtung für ein bewegbares Möbelteil zu schaffen, die kompakt aufgebaut ist und eine einfache Synchronisierung zweier Ausstoßeinheiten ermöglicht.It is therefore the object of the present invention to create an ejection device for a movable furniture part which is of compact design and enables two ejection units to be easily synchronized.

Diese Aufgabe wird mit einer Ausstoßvorrichtung mit den Merkmalen des Anspruches 1 gelöst.This object is achieved with an ejection device having the features of claim 1.

Erfindungsgemäß sind die beiden Ausstoßeinheiten hinsichtlich der Entriegelung über ein Kopplungsmittel synchronisiert, das zumindest ein verschwenkbar gelagertes Pendel umfasst. Dadurch kann die Bewegung des Pendels genutzt werden, um bei einer Entriegelung einer Ausstoßeinheit auch die andere Ausstoßeinheit zu entriegeln. Durch das Pendel kann die Position des Verbindungsmittels zwischen den beiden Ausstoßeinheiten optimal positioniert werden, insbesondere auch unterhalb eines Bodens eines Schubkastens. Dadurch entfällt die Notwendigkeit, den Schubkasten mit seiner Rückwand in einem größeren Abstand zu einer Rückwand eines Möbelkorpus anzuordnen.According to the invention, the two ejection units are synchronized with regard to unlocking via a coupling means which comprises at least one pivotably mounted pendulum. As a result, the movement of the pendulum can be used to unlock the other ejection unit when one ejection unit is unlocked. The position of the connecting means between the two ejection units can be optimally positioned by the pendulum, in particular also below a bottom of a drawer. This eliminates the need to arrange the drawer with its rear wall at a greater distance from a rear wall of a furniture body.

Erfindungsgemäß umfasst jede Ausstoßeinheit ein verschwenkbar gelagertes Pendel. Die beiden Pendel sind dabei über eine Verbindungsstange miteinander verbunden, wobei die Verbindungsstange beabstandet von einer Drehachse der zwei Pendel mit den Pendeln verbunden ist. Die Drehachse der beiden Pendel kann dabei in vertikale Richtung oberhalb der Verbindungsstange angeordnet sein, so dass die Pendel nach unten abragen. Dies ermöglicht den Einbau der Pendel an einem Gehäuse, das im Bereich einer Auszugsführung montiert ist. Die Pendel stehen dabei so weit nach unten hervor, dass die Verbindungsstange unterhalb eines Bodens des Schubkastens positioniert werden kann. Zudem kann dann die Schwerkraft den Entriegelungsvorgang unterstützen, da die Gewichtskräfte an den Pendeln in Entriegelungsrichtung wirken.According to the invention, each ejector unit comprises a pivotably mounted pendulum. The two pendulums are connected to one another via a connecting rod, the connecting rod being connected to the pendulums at a distance from an axis of rotation of the two pendulums. The axis of rotation of the two pendulums can be arranged in the vertical direction above the connecting rod, so that the pendulums protrude downwards. This enables the pendulum to be installed on a housing that is mounted in the area of a pull-out guide. The pendulums protrude so far down that the connecting rod can be positioned below a bottom of the drawer. In addition, gravity can then support the unlocking process, since the weight forces act on the pendulums in the unlocking direction.

Ein Pendel umfasst dabei einen Pendelarm, der um eine Drehachse verschwenkbar gelagert ist. Die Kopplung der beiden Pendelarme über eine Verbindungsstange ermöglicht ein feinfühliges System, das geringe Schaltwege benötigt und nur geringe Kräfte übertragen muss, da die Länge des Pendelarms für eine entsprechende Kraftübersetzung sorgt.A pendulum includes a pendulum arm which is mounted pivotably about an axis of rotation. The coupling of the two pendulum arms via a The connecting rod enables a sensitive system that requires short switching travel and only needs to transmit low forces, as the length of the pendulum arm ensures a corresponding force transmission.

Die verbundenen Pendel weisen vorzugsweise eine horizontale Drehachse auf. Die Verbindungsstange der Pendel bewegt sich annähernd parallel zur gedachten Drehachse der verbundenen Pendel. Auf Grund von Fertigungstoleranzen oder anderen konstruktiven Gegebenheiten kann die gedachte Drehachse zwischen den verbundenen Pendeln von der Horizontalen abweichen.The connected pendulums preferably have a horizontal axis of rotation. The connecting rod of the pendulum moves approximately parallel to the imaginary axis of rotation of the connected pendulum. Due to manufacturing tolerances or other structural conditions, the imaginary axis of rotation between the connected pendulums can deviate from the horizontal.

In einer Ausgestaltung ist jede Ausstoßeinheit durch Eindrücken des bewegbaren Möbelteils von der Schließstellung in eine Überdrückstellung entriegelbar. Das bewegbare Möbelteil kann dabei als Schubkasten ausgebildet sein, aber auch ein Einsatz bei Türen, Klappen, Schiebetüren oder anderen bewegbaren Möbelteilen ist möglich. Durch das Entriegeln durch Eindrücken des bewegbaren Möbelteils kann eine Entriegelung durch einen "Push-to-open" Rastmechanismus erfolgen.In one embodiment, each ejection unit can be unlocked by pressing the movable furniture part from the closed position into an overpressing position. The movable furniture part can be designed as a drawer, but it can also be used for doors, flaps, sliding doors or other movable furniture parts. Unlocking by pressing in the movable furniture part enables unlocking by means of a "push-to-open" latching mechanism.

Vorzugsweise weist jede Ausstoßeinheit ein Gehäuse auf, an der ein Pendel drehbar gelagert ist. Jeweils ein Pendel kann dabei an dem Gehäuse an einer Lageraufnahme verrastet sein, so dass eine leichte Montage des Pendels möglich ist. Über das Pendel kann dabei ein Betätigungsarm bewegt werden, der zur Entriegelung zusammen mit dem Pendel verschwenkt wird.Each ejection unit preferably has a housing on which a pendulum is rotatably mounted. In each case one pendulum can be latched onto a bearing receptacle on the housing, so that easy assembly of the pendulum is possible. An actuating arm can be moved via the pendulum and is pivoted together with the pendulum for unlocking.

Das Pendel ist vorzugsweise mit einem an einem Gehäuse geführten Schieber verbunden, mittels dem ein Rastmechanismus der Ausstoßeinheit entriegelbar ist. Statt dem Schieber kann auch ein Schwenkarm oder ein anderes Stellelement wie z.B. eine Getriebeanordnung für die Entriegelung eingesetzt werden.The pendulum is preferably connected to a slide guided on a housing, by means of which a latching mechanism of the ejection unit can be unlocked. Instead of the slide, a swivel arm or another adjusting element such as e.g. a gear assembly can be used for unlocking.

An einem Gehäuse der Ausstoßeinheit kann bevorzugt eine schlaufenförmige Führungsbahn für ein Steuerelement ausgebildet sein, das an einer Rastaufnahme der Führungsbahn bei gespanntem Kraftspeicher verriegelbar ist. Die Rastaufnahme kann dabei mehrteilig ausgebildet sein, mit einem ersten Teil, das beispielsweise integral mit dem Gehäuse ausgebildet ist und einem relativ zu dem ersten Teil bewegbaren zweiten Teil, das zur Entriegelung ein Stellelement, insbesondere einen Schieber, aufweist, der über das Pendel bewegbar ist. Das Stellelement kann dabei in einer geöffneten Position der Rastaufnahme verrastet werden. Dadurch weist die Rastaufnahme eine geschlossene Position zur Verriegelung des Steuerelementes und eine offene Position auf, in der das Steuerelement zwischen den beiden Teilen der Rastaufnahme hindurch bewegt werden kann. Der bewegbare Teil der Rastaufnahme kann dabei durch eine Feder in die geschlossene Position vorgespannt sein.A loop-shaped guide track for a control element can preferably be formed on a housing of the ejection unit, which can be locked on a latching receptacle of the guide track when the energy storage device is tensioned. The locking receptacle can be designed in several parts, with a first part, which is, for example, formed integrally with the housing and a second part movable relative to the first part, which has an actuating element, in particular a slide, for unlocking, which can be moved via the pendulum . The adjusting element can be locked in an open position of the locking receptacle. As a result, the latching receptacle has a closed position for locking the control element and an open position in which the control element can be moved through between the two parts of the locking receptacle. The movable part of the locking receptacle can be biased into the closed position by a spring.

In einer weiteren Ausgestaltung ist an jedem Gehäuse einer Ausstoßeinheit ein Auswerferelement entlang einer Führung geführt, das durch einen Kraftspeicher in Öffnungsrichtung vorgespannt ist. Die Führung kann dabei im Wesentlichen senkrecht zur Drehachse des Pendels ausgerichtet sein und beispielsweise parallel zu einer Längsrichtung einer benachbarten Auszugsführung verlaufen. Dadurch kann der Bauraum benachbart zu der Auszugsführung genutzt werden, um das Gehäuse der Ausstoßeinheit unterzubringen.In a further embodiment, an ejector element is guided along a guide on each housing of an ejector unit and is pretensioned in the opening direction by an energy store. The guide can be oriented essentially perpendicular to the axis of rotation of the pendulum and run, for example, parallel to a longitudinal direction of an adjacent pull-out guide. As a result, the installation space adjacent to the pull-out guide can be used to accommodate the housing of the ejection unit.

Das Pendel zur Verbindung der beiden Ausstoßeinheiten kann vorzugsweise um einen Winkel kleiner als 90°, vorzugsweise kleiner als 60°, verschwenkt werden. Eine Bewegung des Pendels zwischen 5° und 30° kann ausreichend sein, um die beiden Ausstoßeinheiten bei der Entriegelung zu synchronisieren.The pendulum for connecting the two ejection units can preferably be pivoted through an angle smaller than 90 °, preferably smaller than 60 °. A movement of the pendulum between 5 ° and 30 ° can be sufficient to synchronize the two ejection units when unlocking.

Die erfindungsgemäße Ausstoßvorrichtung wird vorzugsweise bei einem Möbel mit mindestens einem Schubkasten eingesetzt. Aber auch ein Einsatz bei Haushaltsgeräten mit Schubkästen ist vorteilhaft.The ejection device according to the invention is preferably used in a piece of furniture with at least one drawer. Use in household appliances with drawers is also advantageous.

In den Figuren 1A und 1B ist ein Schubkasten 1 gezeigt, der an einem Möbel oder einem Haushaltsgerät montierbar ist und eine Frontblende 2 aufweist, die mit zwei Seitenzargen 3 verbunden ist. An jeder Seitenzarge 3 ist eine Auszugsführung 4 vorgesehen, wobei jede Auszugsführung 4 über ein Befestigungselement 5 an einem umgebenden Korpus montiert ist. Der bewegbare Teil der Auszugsführung ist mit Haltern 6 verbunden, die einen Boden 50 des Schubkastens stützen.In the Figures 1A and 1B a drawer 1 is shown which can be mounted on a piece of furniture or a household appliance and has a front panel 2 which is connected to two side frames 3. A pull-out guide 4 is provided on each side frame 3, each pull-out guide 4 being mounted on a surrounding body via a fastening element 5. The movable part of the pull-out guide is connected to holders 6 which support a bottom 50 of the drawer.

Um den Schubkasten 1 aus einer Schließposition in Öffnungsrichtung zu bewegen, sind eine erste Ausstoßeinheit 7 und eine zweite Ausstoßeinheit 7' vorgesehen, die an gegenüberliegenden Seiten des Schubkastens 1 jeweils an einer Auszugsführung 4 angeordnet sind. Es ist auch möglich, dass die Ausstoßeinheit 7, 7' in der Schubkastenzarge angeordnet ist. Hier sind unterschiedlichste Anordnungskombinationen von Ausstoßeinheiten Stand der Technik bekannt. Jede Ausstoßeinheit 7 umfasst ein Gehäuse 8, an dem eine Führungsbahn 9 im Wesentlichen parallel zur Längsrichtung der Auszugsführung 4 angeordnet ist. An der Führungsbahn 9 ist ein Auswerferelement 10 geführt, das zumindest über einen Teil der Wegstrecke des Schubkastens 1 in Öffnungs- und Schließrichtung koppelbar ist, um den Schubkasten 1 beim Öffnen auszuwerfen und beim Schließen einen Kraftspeicher der Ausstoßeinheit 7 oder 7' zu spannen. Die Bewegungsrichtung des Auswerferelementes 10 ist dabei im Wesentlichen parallel zur Längsrichtung der Auszugsführung 4 bis zu einem abgewinkelten Endabschnitt, an dem die Kopplung zwischen dem Schubkasten 1 und dem Auswerferelement 10 entkoppelt wird.In order to move the drawer 1 from a closed position in the opening direction, a first ejector unit 7 and a second ejector unit 7 'are provided, which are each arranged on a pull-out guide 4 on opposite sides of the drawer 1. It is also possible for the ejector unit 7, 7 'to be arranged in the drawer frame. A wide variety of arrangement combinations of ejection units are known from the prior art. Each ejection unit 7 comprises a housing 8 on which a guide track 9 is arranged essentially parallel to the longitudinal direction of the pull-out guide 4. An ejector element 10 is guided on the guide track 9, which can be coupled at least over part of the path of the drawer 1 in the opening and closing directions in order to eject the drawer 1 when it is opened and to add an energy storage device to the ejection unit 7 or 7 'when it is closed tighten. The direction of movement of the ejector element 10 is essentially parallel to the longitudinal direction of the pull-out guide 4 up to an angled end section at which the coupling between the drawer 1 and the ejector element 10 is decoupled.

Die erste Ausstoßeinheit 7 ist mit der zweiten Ausstoßeinheit 7' über Kopplungsmittel synchronisiert, damit eine Entriegelung der beiden Ausstoßeinheiten 7 und 7' möglichst gleichzeitig erfolgt. Die Kopplungsmittel umfassen dabei eine Verbindungsstange 40, die zwischen zwei Pendeln 14 der Ausstoßeinheiten 7 und 7' angeordnet ist. Die Verbindungsstange 40 ist dabei unterhalb des Bodens 50 des Schubkastens positioniert, so dass eine Rückwand des Schubkastens 1 benachbart zu einer Rückwand eines Möbelkorpus oder eines Haushaltsgerätes angeordnet werden kann. Die Anordnung der Verbindungstange 40 ist abhängig vom Anwendungsfall. Falls der Schubkasten z.B. als Hängeregisterschub oder Mülleimerschub ausgeführt ist, kann die Verbindungsstange mittels der Pendel z.B. im Bereich unterhalb der Rückwand verlegt werden. Falls der Schubkasten eine Aussparung für ein Siphon aufweist, kann die Verbindungsstange 40 mittels der Pendel weiter nach vorne unterhalb des Schubkastenbodens verlegt werden. Bei Sonderanwendungen kann es auch möglich sein, dass die Verbindungsstange 40 mittels der Pendel oberhalb der Zarge verläuft.The first ejection unit 7 is synchronized with the second ejection unit 7 'via coupling means so that the two ejection units 7 and 7' are unlocked as simultaneously as possible. The coupling means include a connecting rod 40 which is arranged between two pendulums 14 of the ejection units 7 and 7 '. The connecting rod 40 is positioned below the bottom 50 of the drawer, so that a rear wall of the drawer 1 can be arranged adjacent to a rear wall of a furniture body or a household appliance. The arrangement of the connecting rod 40 depends on the application. If the drawer is e.g. is designed as a suspension file drawer or a rubbish bin drawer, the connecting rod can e.g. be laid in the area below the rear wall. If the drawer has a recess for a siphon, the connecting rod 40 can be moved further forwards below the bottom of the drawer by means of the pendulum. In the case of special applications, it may also be possible for the connecting rod 40 to run above the frame by means of the pendulum.

Die beiden Ausstoßeinheiten 7 und 7' können spiegelsymmetrisch zu einer Mittelebene ausgebildet sein, wobei nachfolgend nur die Ausstoßeinheit 7 beschrieben wird, da die Ausstoßeinheit 7' die gleiche Funktionalität besitzt wie die Ausstoßeinheit 7.The two ejection units 7 and 7 ′ can be designed mirror-symmetrically to a center plane, only the ejection unit 7 being described below, since the ejection unit 7 ′ has the same functionality as the ejection unit 7.

Die Ausstoßeinheit 7 ist in Figur 3 dargestellt. Das Auswerferelement 10 ist als Mitnehmer entlang der Führungsbahn 9 an dem Gehäuse 8 verschiebbar. An dem Gehäuse 8 befindet sich eine Patrone 12 mit einem Kraftspeicher, mittels dem das Auswerferelement 10 in Öffnungsrichtung vorgespannt ist. Das Auswerferelement 10 ist über einen Rastmechanismus mit gespanntem Kraftspeicher verriegelbar, wobei zur Entriegelung das bewegbare Möbelteil in Schließrichtung eingedrückt werden kann, wodurch ein Schieber 13 bewegt wird, der mit einem Pendel 14 der Ausstoßeinheit 7 gekoppelt ist. Dadurch kann eine Schwenkbewegung des Pendels 14 der Ausstoßeinheit 7 über die Verbindungsstange 40, die an gegenüberliegenden Seiten an Zapfen 15 gehalten ist, auch eine Entriegelung der Ausstoßeinheit 7' bewirken, auch wenn die Frontblende 2 des Schubkastens beispielsweise nur an einer Seite eingedrückt wird.The ejection unit 7 is in Figure 3 shown. The ejector element 10 can be displaced as a driver along the guide track 9 on the housing 8. On the housing 8 there is a cartridge 12 with an energy store, by means of which the ejector element 10 is biased in the opening direction. The ejector element 10 can be locked via a latching mechanism with a tensioned energy storage device, whereby the movable furniture part can be pressed in the closing direction for unlocking, thereby moving a slide 13 which is coupled to a pendulum 14 of the ejector unit 7. As a result, a pivoting movement of the pendulum 14 of the ejection unit 7 via the connecting rod 40, which is held on opposite sides on the pin 15, also unlocks the ejection unit 7 ', even if the Front panel 2 of the drawer, for example, is only pressed in on one side.

Wie in den Figuren 4A bis 4C gezeigt ist, befindet sich das Pendel 14 an einer Lageraufnahme 19 an dem Gehäuse 8 und ist dort verrastet. Ein Zapfen 15 zur Fixierung der Verbindungsstange 40 ist beabstandet von einer Drehachse 16 angeordnet, beispielsweise in einem Abstand zwischen 0,5 cm bis 2 cm, so dass für ein Entriegeln nur ein geringfügiges Verschwenken des Pendels 14 erforderlich ist. Abhängig von der Nutzung des Schubkastens kann die Verbindungsstange 40 auch in einem größeren Abstand von der Drehachse 16 beabstandet sein.As in the Figures 4A to 4C is shown, the pendulum 14 is located on a bearing receptacle 19 on the housing 8 and is locked there. A pin 15 for fixing the connecting rod 40 is arranged at a distance from an axis of rotation 16, for example at a distance between 0.5 cm to 2 cm, so that only a slight pivoting of the pendulum 14 is required for unlocking. Depending on the use of the drawer, the connecting rod 40 can also be spaced apart from the axis of rotation 16 at a greater distance.

Wie in Figur 4B und in den Figuren 5A bis 5C gezeigt ist, lässt sich das Pendel 14 um eine Drehachse 16 drehen, die an der Lageraufnahme 19 gehalten ist. Mit dem Pendel 14 ist ein Betätigungsarm 17 drehfest gekoppelt, der in einer Aufnahme 18 eingreift, die mit einem Schieber 13 verbunden ist. Der Schieber 13 ist über eine Feder 32 in Öffnungsrichtung vorgespannt. Hierfür ist die Feder 32 auf einer Seite an einem Steg 34 des Gehäuses 8 abgestützt und an der gegenüberliegenden Seite an einem Steg 33, der mit dem Schieber 13 verbunden ist. Durch Verschwenken des Pendels 14 und des Betätigungsarms 17 in Figur 4B gegen den Uhrzeigersinn wird der Schieber 13 gegen die Kraft der Feder 32 in Schließrichtung bewegt.As in Figure 4B and in the Figures 5A to 5C is shown, the pendulum 14 can be rotated about an axis of rotation 16, which is held on the bearing receptacle 19. An actuating arm 17, which engages in a receptacle 18 which is connected to a slide 13, is coupled in a rotationally fixed manner to the pendulum 14. The slide 13 is pretensioned in the opening direction via a spring 32. For this purpose, the spring 32 is supported on one side on a web 34 of the housing 8 and on the opposite side on a web 33 which is connected to the slide 13. By pivoting the pendulum 14 and the actuating arm 17 in Figure 4B counterclockwise the slide 13 is moved against the force of the spring 32 in the closing direction.

Das Pendel 14 kann integral mit dem Betätigungsarm 17 und einem Lager ausgebildet sein, das an der Lageraufnahme 19 verrastbar ist.The pendulum 14 can be formed integrally with the actuating arm 17 and a bearing which can be latched on the bearing receptacle 19.

In Figur 4B ist noch die Abstützung eines Kraftspeichers 30 in Form einer Druckfeder gezeigt, die an einem Halter 31 an dem Gehäuse 8 fixiert ist und das Auswerferelement 10 in Öffnungsrichtung vorspannt.In Figure 4B the support of an energy accumulator 30 in the form of a compression spring is also shown, which is fixed to a holder 31 on the housing 8 and biases the ejector element 10 in the opening direction.

In den Figuren 6A und 6B ist ein Rastmechanismus an dem Gehäuse 8 gezeigt, mittels dem das Auswerferelement 10 bei gespanntem Kraftspeicher 30 verrastet ist. Der Rastmechanismus umfasst eine an dem Gehäuse 8 ausgebildete Führungsbahn 20, die schlaufenförmig ausgebildet ist und ein erstes Teil 22 einer Rastaufnahme umfasst. An der Führungsbahn 20 ist ein Steuerelement 21, insbesondere ein abgewinkelter Draht, geführt, der mit dem Auswerferelement 10 gekoppelt ist. In den Figuren 6A und 6B befindet sich das Steuerelement 21 in einer verrasteten Position, bei der ein zweiter Teil 23 der Rastaufnahme zusammen mit dem ersten Teil 22 der Rastaufnahme geschlossen ist. Der zweite Teil 23 der Rastaufnahme ist an dem Schieber 13 angeformt, so dass die Rastaufnahme mehrteilig ausgebildet ist.In the Figures 6A and 6B a locking mechanism is shown on the housing 8, by means of which the ejector element 10 is locked when the force storage device 30 is tensioned. The latching mechanism comprises a guide track 20 formed on the housing 8, which is loop-shaped and comprises a first part 22 of a latching receptacle. A control element 21, in particular an angled wire, which is coupled to the ejector element 10, is guided on the guide track 20. In the Figures 6A and 6B the control element 21 is in a latched position in which a second part 23 of the latching receptacle is closed together with the first part 22 of the latching receptacle is. The second part 23 of the latching receptacle is integrally formed on the slide 13, so that the latching receptacle is formed in several parts.

Will der Benutzer das bewegbare Möbelteil aus der Schließposition öffnen, wird der Schubkasten in Schließrichtung eingedrückt und in eine Überdrückstellung bewegt. Dadurch bewegt sich auch das Auswerferelement 10 in Schließrichtung und verfährt hierbei über das Steuerelement 21 auch den zweiten Teil 23 der Rastaufnahme, wie dies in den Figuren 7A und 7B gezeigt ist. Durch das Verfahren des Schiebers 13 gegen die Kraft der Feder 32 wird auch der Betätigungsarm 17 an der Aufnahme 18 bewegt, und das Pendel 14 verschwenkt in Schließrichtung. Dadurch wird auch die Verbindungsstange 40 verschwenkt, die dafür sorgt, dass auch die Ausstoßeinheit 7' entriegelt wird, falls dort nicht gleichzeitig eine Entriegelungsbewegung ausgeführt wurde. Dadurch wird gewährleistet, dass in jedem Fall beide Ausstoßeinheiten 7 und 7' entriegelt werden.If the user wants to open the movable furniture part from the closed position, the drawer is pushed in in the closing direction and moved into an overpressure position. As a result, the ejector element 10 also moves in the closing direction and also moves the second part 23 of the latching receptacle via the control element 21, as shown in FIG Figures 7A and 7B is shown. By moving the slide 13 against the force of the spring 32, the actuating arm 17 is also moved on the receptacle 18, and the pendulum 14 is pivoted in the closing direction. As a result, the connecting rod 40 is also pivoted, which ensures that the ejector unit 7 ′ is also unlocked if an unlocking movement was not carried out there at the same time. This ensures that both ejection units 7 and 7 'are unlocked in any case.

In den Figuren 8A bis 8C ist gezeigt, dass zwischen dem ersten Teil 22 und dem zweiten Teil 23 der Rastaufnahme ein Spalt gebildet ist, durch den das Steuerelement 21 in Öffnungsrichtung entweichen kann. Dadurch kann das Auswerferelement 10 durch die Kraft des Kraftspeichers 30 in Öffnungsrichtung bewegt werden, um das bewegbare Möbelteil auszuwerfen. Der zweite Teil 23 der Rastaufnahme wird dabei in einer geöffneten Position verrastet, wobei hierfür ein Arm 24 an einem Vorsprung 25 des Gehäuses 8 verrastet wird, in dem eine Spitze 28 auf dem Vorsprung 25 aufliegt. Dadurch verbleibt der zweite Teil 23 der Rastaufnahme in einer Position, in der ein Durchfahren des Steuerelementes 21 ermöglicht wird.In the Figures 8A to 8C it is shown that a gap is formed between the first part 22 and the second part 23 of the latching receptacle, through which the control element 21 can escape in the opening direction. As a result, the ejector element 10 can be moved in the opening direction by the force of the energy store 30 in order to eject the movable furniture part. The second part 23 of the latching receptacle is latched in an open position, an arm 24 being latched for this purpose on a projection 25 of the housing 8 in which a tip 28 rests on the projection 25. As a result, the second part 23 of the latching receptacle remains in a position in which it is possible to drive through the control element 21.

Wird das bewegbare Möbelteil weiter in Öffnungsrichtung bewegt, wird der zweite Teil 23 der Rastaufnahme entriegelt, wie dies in Figur 9A gezeigt ist. Ein abgewinkelter Endabschnitt 26 des Steuerelementes 21 wirkt auf eine Anlaufschräge 27 an dem Arm 24, der dadurch verschwenkt wird. Dies führt dazu, dass der Arm 24 so weit verschwenkt, dass die Spitze 28 von dem Vorsprung 25 entfernt wird, so dass nun der Arm 24 zusammen mit dem Schieber 13 aufgrund der Kraft der Feder 32 verfahren wird. Der Arm 24 wird nun mit der Spitze 28 an einer Auflage 29 abgestützt, wie dies in Figur 10B gezeigt ist. Die Auflage 29 ist beabstandet zu dem Vorsprung 25 angeordnet, wobei der Verstellweg des Armes 24 und des zweiten Teils 23 der Rastaufnahme im Bereich zwischen 1 mm bis 3 mm liegt, so dass nur geringe Wegstrecken vorhanden sind. Wenn die Spitze 28 an der Auflage 29 abgestützt ist, befindet sich die Rastaufnahme wieder in der geschlossenen Position, wie dies in den Figuren 6A und 6B gezeigt ist.If the movable furniture part is moved further in the opening direction, the second part 23 of the latching receptacle is unlocked, as shown in FIG Figure 9A is shown. An angled end section 26 of the control element 21 acts on a bevel 27 on the arm 24, which is pivoted as a result. This results in the arm 24 being pivoted so far that the tip 28 is removed from the projection 25, so that the arm 24 is now moved together with the slide 13 due to the force of the spring 32. The arm 24 is now supported with the tip 28 on a support 29, as shown in FIG Figure 10B is shown. The support 29 is arranged at a distance from the projection 25, the adjustment path of the arm 24 and the second part 23 of the latching receptacle being in the range between 1 mm and 3 mm, so that only short distances are present. When the tip 28 is supported on the support 29, the Locking receptacle back in the closed position, as shown in the Figures 6A and 6B is shown.

In Figur 11 ist das Gehäuse 8 im Bereich der Führungsbahn 20 ohne Steuerelement dargestellt. Integral mit dem Gehäuse 8 ist eine schlaufenförmige Führungsbahn mit dem ersten Teil 22 der Rastaufnahme angeordnet, wobei der auf der rechten Seite angeordnete Kanal 35 in Öffnungsrichtung durchfahren wird, und der auf der linken Seite angeordnete Kanal in Schließrichtung.In Figure 11 the housing 8 is shown in the region of the guide track 20 without a control element. A loop-shaped guide track with the first part 22 of the latching receptacle is arranged integral with the housing 8, the channel 35 arranged on the right side being traversed in the opening direction and the channel arranged on the left side being traversed in the closing direction.

In dem dargestellten Ausführungsbeispiel wird die Kraftübertragung beim Entriegeln über einen linear verfahrbaren Schieber 13 bewirkt. Es ist auch möglich, statt einem linear verfahrbaren Schieber 13 einen verschwenkbaren Hebel oder ein anderes Betätigungselement vorzusehen, um eine Entriegelung des Rastmechanismus auf das Pendel 14 zu übertragen. Auch andere Rastmechanismen können für eine Ausstoßeinheit 7 oder 7' eingesetzt werden.In the exemplary embodiment shown, the force is transmitted during unlocking via a linearly movable slide 13. It is also possible, instead of a linearly displaceable slide 13, to provide a pivotable lever or another actuating element in order to transmit an unlocking of the latching mechanism to the pendulum 14. Other locking mechanisms can also be used for an ejector unit 7 or 7 '.
