Description

Die Erfindung betrifft einen Ausstoßer zum Ausstoßen eines bewegbaren Möbelteils aus einer geschlossenen Endlage in bzw. an einem Möbelkorpus mit einem durch eine elektrische Antriebseinheit - insbesondere einem Elektromotor - antreibbaren Ausstoßhebel, wobei der Ausstoßhebel einen ersten Ausstoßhebelteil und einen relativ dazu beweglichen zweiten Ausstoßhebelteil aufweist.The invention relates to an ejector for ejecting a movable furniture part from a closed end position in or on a furniture body with a by an electric drive unit - in particular an electric motor - driven ejection lever, wherein the ejection lever has a first ejection lever part and a relatively movable second ejection lever part.

Weiters betrifft die Erfindung ein Möbel mit einem Möbelkorpus und einem bewegbar gelagerten Möbelteil und einem Ausstoßer zum Ausstoßen des bewegbaren Möbelteils.Furthermore, the invention relates to a piece of furniture with a furniture body and a movably mounted furniture part and an ejector for ejecting the movable furniture part.

Derartige Ausstoßer sind bereits aus dem Stand der Technik bekannt. Hauptsächlich werden mit derartigen Ausstoßern entweder Schubladen oder auch Möbelklappen ausgestoßen, was zu einem bedienerfreundlicheren Möbel führt.Such ejectors are already known from the prior art. Mainly with such ejectors either drawers or furniture flaps are ejected, resulting in a user-friendly furniture.

So zeigt etwa die WO 2008/092176 A1 vom 12. Dezember 2007 einen Ausstoßhebel für einen Ausstoßer zum Ausstoßen eines bewegbaren Möbelteils aus einer geschlossenen Endlage in bzw. an einen Möbelkorpus, mit einem länglichen Hebelkörper, wobei der Hebelkörper längenveränderlich ausgebildet ist.So shows about the WO 2008/092176 A1 December 12, 2007, an ejection lever for an ejector for ejecting a movable furniture part from a closed end position in or on a furniture body, with an elongated lever body, wherein the lever body is formed variable in length.

Weiters zeigt die WO 2010/015513 A1 vom 22. Juli 2009 eine in einen Möbelkorpus einbaubare Ausstoßeinrichtung, mit einem eine Anlagefläche aufweisenden Ausstoßhebel, der in einem Tragteil aus einer Nichtgebrauchsstellung in eine Gebrauchsstellung herausschwenkbar gelagert ist, von der in seiner Längserstreckung aus einem an einem Drehlager angeschlossenem Hebelarm und einem damit verbundenen Verlängerungsschenkel besteht, wobei der Verlängerungsschenkel in Ausschwenkrichtung des Ausstoßhebels einknickbar am Hebelarm angelenkt ist.Furthermore, the shows WO 2010/015513 A1 of 22 July 2009, a fitted into a furniture body ejector, with a contact surface having ejection lever which is pivotally mounted in a support member from a non-use position in a use position of the longitudinal extension of a connected to a pivot lever arm and an associated extension leg consists, wherein the extension leg is articulated einknickbar in the swinging of the ejection lever on the lever arm.

Weiters zeigt die DE 20 2006 011 039 U1 vom 6. Dezember 2007 einen Ausstoßhebel, der in seiner Länge verstellbar ausgebildet ist, insbesondere für eine Einstellung der Teilstrecke des ersten Möbelteils, über welche das erste Möbelteil mit dem Verschwenken des Ausstoßhebels angetrieben bewegbar ist.Furthermore, the shows DE 20 2006 011 039 U1 of 6 December 2007 an ejection lever, which is designed to be adjustable in length, in particular for an adjustment of the section of the first furniture part, via which the first furniture part driven by the pivoting of the ejection lever is movable.

Aufgabe der Erfindung ist es, einen verbesserten Ausstoßer zum Ausstoßen eines bewegbaren Möbelteiles anzugeben.The object of the invention is to provide an improved ejector for ejecting a movable furniture part.

Dies wird am erfindungsgemäßen Ausstoßer durch die Merkmale des Anspruchs 1 gelöst.This is achieved by the features of claim 1 on the ejector according to the invention.

Durch einen mit der Öffnungsbewegung sich in seiner Länge veränderten Ausstoßhebel kann der Ausstoßvorgang bezüglich des Ausstoßweges und des zu übertragenden Drehmomentes beeinflusst werden.By means of an ejection lever modified with the opening movement in its length, the ejection process with respect to the ejection path and the torque to be transmitted can be influenced.

Für verschiedene Anwendungsfälle, wo bisher unterschiedliche Ausstoßhebel hergestellt werden mussten (kürzere bzw. längere), kann dies nun mit einem einzigen längenveränderbaren Ausstoßhebel gelöst werden, was zu geringeren Herstellungskosten in Summe führt.For different applications, where previously different ejector had to be made (shorter or longer), this can now be solved with a single length-adjustable ejection lever, resulting in lower production costs in total.

Dadurch, dass die beiden Ausstoßhebelteile zueinander verschoben werden um die Länge des Ausstoßhebels während des Ausstoßvorganges zu verändern, wird ein Knicken des Ausstoßhebels vermeidbar und findet somit knickfrei statt, was zu einem stabileren Ausstoßhebel führen kann.Characterized in that the two ejection lever parts are shifted from each other to change the length of the ejection lever during the ejection process, a buckling of the ejection lever is avoidable and thus takes place kink-free, which can lead to a more stable ejection lever.

Weitere vorteilhafte Ausführungsformen der Erfindung sind in den abhängigen Ansprüchen definiert.Further advantageous embodiments of the invention are defined in the dependent claims.

Als besonders vorteilhaft hat es sich dabei herausgestellt, wenn der Ausstoßhebel während des Ausstoßvorganges seine Länge vergrößert. Durch einen mit der Öffnungsbewegung "mitwachsenden" Ausstoßhebel wird ein verbesserter Ausstoßvorgang erreichbar, da der Ausstoßhebel immer länger wird, was bewirkt, dass der Ausstoßhebel längere Zeit und über einen längeren Ausstoßweg mit dem beweglichen Möbelteil verbunden ist und dies somit zu einem bevorzugten Ausstoßvorgang führt.It has proven to be particularly advantageous when the ejection lever increases its length during the ejection process. By an ejection lever "growing" with the opening movement, an improved ejection operation becomes attainable, as the ejection lever becomes longer and longer, causing the ejection lever to be connected to the movable furniture member for a longer time and through a longer ejection path, thus leading to a preferable ejection operation.

In eingefahrenem Zustand weist ein solcher Ausstoßhebel einen geringen Platzbedarf auf, er verfügt über ein gutes Drehmomentverhalten beim Anfahren, da der Hebelabstand am Anfang geringer ist.When retracted, such a discharge lever has a small footprint, it has a good torque behavior when starting, since the lever distance is initially lower.

Selbst bei schmalen Korpussen kann er wegen seinem geringen Platzbedarf zum Einsatz kommen und ein derart längenveränderbarer Ausstoßhebel kann leichter in einen Ausstoßer integriert werden als dies ein großer Ausstoßhebel erlauben würde.Even with narrow carcasses, it can be used because of its small footprint and such a variable length ejector lever can be easily integrated into an ejector than would allow a large ejection lever.

Als vorteilhaft hat es sich weiters herausgestellt, dass der Ausstoßhebel während des Ausstoßvorganges seine Länge verkleinert. Durch einen während des Ausstoßvorganges sich in seiner Länge verkürzenden Ausstoßhebel kann ebenfalls bevorzugt auf das zu übertragende Drehmoment Einfluss genommen werden.It has also proven to be advantageous that the ejection lever reduces its length during the ejection process. By a during the ejection process in its length shortening ejection lever can also be preferably influenced on the torque to be transmitted.

Als besonders vorteilhaft hat es sich herausgestellt, wenn die Verstellvorrichtung im Wesentlichen vollständig mechanisch ausgebildet ist und / oder ein Hebelwerk und/oder ein Getriebe aufweist, da eine rein mechanische Ausbildung der Verstellvorrichtung kostengünstig herstellbar ist und/oder da über ein Hebelwerk und/oder einem Getriebe auf einfache mechanische Art und Weise eine Längenveränderung des Ausstoßhebels erzielbar ist.To be particularly advantageous, it has been found that the adjusting device is substantially completely formed mechanically and / or has a lever mechanism and / or a transmission, since a purely mechanical design of the adjustment is inexpensive to produce and / or because of a lever mechanism and / or a Transmission in a simple mechanical manner, a change in length of the ejection lever is achieved.

Gemäß einem bevorzugten Ausführungsbeispiel kann vorgesehen sein, dass die Verstellvorrichtung zumindest teilweise - vorzugsweise im Wesentlichen vollständig - im Inneren des Ausstoßhebels ausgebildet ist. Speziell durch die Ausbildung mit einem Getriebe kann die Verstellvorrichtung im Wesentlichen vollständig im Inneren des Ausstoßhebels ausgebildet werden, was zu geringen Baugrößen und somit zu einem kompakten Ausstoßer führen kann.According to a preferred embodiment it can be provided that the adjusting device is at least partially - preferably substantially completely - formed in the interior of the ejection lever. Specifically, by training with a gearbox, the adjusting device can be substantially completely formed in the interior of the ejection lever, which can lead to small sizes and thus to a compact ejector.

In einem bevorzugten Ausführungsbeispiel kann vorgesehen sein, dass der Ausstoßhebel zumindest einen ersten Ausstoßhebelteil und einen zweiten Ausstoßhebelteil aufweist, wobei der zweite Ausstoßhebelteil - vorzugsweise im Wesentlichen linear - beweglich zum ersten Ausstoßhebelteil ausgebildet ist.In a preferred embodiment, it may be provided that the ejection lever has at least one first ejection lever part and a second ejection lever part, wherein the second ejection lever part is formed-preferably substantially linearly-movable relative to the first ejection lever part.

Weiters kann bevorzugt vorgesehen sein, dass die Verstellvorrichtung zumindest teilweise am Ausstoßhebel ausgebildet ist und / oder zumindest am - vorzugsweise im Wesentlichen linear - beweglichen zweiten Ausstoßhebelteil des Ausstoßhebel angeordnet ist.Furthermore, it can preferably be provided that the adjusting device is at least partially formed on the ejection lever and / or at least on - preferably substantially linearly movable - second ejection lever part of the ejection lever is arranged.

Als besonders vorteilhaft hat es sich erwiesen, wenn das Hebelwerk zumindest einen - vorzugsweise zwei - Hebel aufweist, wobei der Hebel während des Ausstoßvorganges den beweglichen zweiten Ausstoßhebelteil im Wesentlichen linear zum ersten Ausstoßhebelteil verfährt.It has proved to be particularly advantageous if the lever mechanism has at least one lever, preferably two, with the lever during the ejection process the movable second ejection lever part moves substantially linearly to the first ejection lever part.

Besonders bevorzugt kann vorgesehen sein, dass der bewegliche zweite Ausstoßhebeiteil am durch das Hebelwerk unbewegten ersten Ausstoßhebelteil des Ausstoßhebels - vorzugsweise im eingefahrenen Zustand, während des Verfahrens und im ausgefahrenen Zustand - lose anliegt. Somit ist zu jeder Zeit das Verschwenken des Ausstoßhebels gewährleistbar, dass sich der zweite Ausstoßhebelteil vom ersten Ausstoßhebelteil entfernen kann.Particularly preferably, it can be provided that the movable second Ausstoßhebeiteil loosely at the immovable by the lever mechanism first ejection lever part of the ejection lever - preferably in the retracted state, during the process and in the extended state. Thus, at any time, the pivoting of the ejection lever can be ensured that the second ejection lever part can move away from the first ejection lever part.

Als besonders vorteilhaft hat es sich dabei herausgestellt, wenn der Hebel am beweglichen zweiten Ausstoßhebelteil des Ausstoßhebels und an einem durch die Antriebseinheit unbewegten Teil des Ausstoßers ausgebildet ist. Durch die Ausbildung des Hebels am beweglichen zweiten Ausstoßhebelteil und an einem unbewegten Teil des Ausstoßers wird automatisch durch das Verschwenken des Ausstoßhebels der zweite Ausstoßhebelteil vom ersten Ausstoßhebelteil wegbewegt.It has proven to be particularly advantageous if the lever is formed on the movable second ejection lever part of the ejection lever and on a part of the ejector which is stationary by the drive unit. By the formation of the lever on the movable second ejection lever part and on a stationary part of the ejector, the second ejection lever part is automatically moved away from the first ejection lever part by the pivoting of the ejection lever.

Gemäß einem bevorzugten Ausführungsbeispiel kann vorgesehen sein, dass der linear bewegte zweite Ausstoßhebelteil des Ausstoßhebels vom durch die Antriebseinheit angetriebenen ersten Ausstoßhebelteil des Ausstoßhebels geführt wird. Durch das Führen des zweiten Ausstoßhebelteils durch den ersten Ausstoßhebelteil kann eine auf Dauer konstante gleichmäßige Bewegung erzielt werden.According to a preferred embodiment, it may be provided that the linearly moving second ejection lever part of the ejection lever is guided by the first ejection lever part of the ejection lever driven by the drive unit. By guiding the second ejection lever part by the first ejection lever part, a constant, constant constant motion can be achieved.

Als vorteilhaft hat es sich weiters herausgestellt, wenn der Ausstoßhebel teleskopierbar ausgebildet ist. Speziell eine Ausführung als teleskopierbarer Ausstoßhebel kann zu einem sowohl kompakten als auch robusten, und somit langlebigen beweglichen und längenveränderbaren Ausstoßhebel führen.It has also proven to be advantageous if the ejection lever is designed to be telescopic. Especially a version as a telescopic ejection lever can lead to a both compact and robust, and thus durable movable and variable length ejector.

Konkret wird auch Schutz begehrt für ein Möbel mit einem Möbelkorpus und einem bewegbar gelagerten Möbelteil und einem Ausstoßer zum Ausstoßen des bewegbaren Möbelteils nach einem der Ansprüche 1 bis 11.Specifically, protection is also sought for a piece of furniture with a furniture body and a movably mounted furniture part and an ejector for ejecting the movable furniture part according to one of claims 1 to 11.

Das Hebelwerk 20 weist dabei zwei Hebel 21 und 22 auf, welche einerseits am beweglichen zweiten Ausstoßhebelteil 12 - genauso genommen an dessen Bolzen 23 - angeordnet sind und andererseits an den unbewegten Teilen 104 des Ausstoßers 100 beweglich angeordnet sind. Während des Ausschwenkens des Ausstoßhebels 1 durch die Antriebseinheit wird durch das Hebelwerk 20 der zweite Ausstoßhebelteil 12 ausgeschoben und bewirkt somit, dass der Ausstoßhebel 1 während des Ausstoßvorganges seine Länge vergrößert. FIG. 1b shows an exploded view of a pusher 100 as just in FIG. 1 a described. The ejection lever 1 here has a first ejection lever part 11 and a second ejection lever part 12, wherein the second ejection lever part 12 is arranged linearly movable relative to the first ejection lever part 11. In this embodiment, the second ejection lever part 12 has a guide groove 13, by means of which the linear mobility on the first ejection lever part 11 can be achieved. The movement of the second ejection lever 12 is performed via the lever mechanism 20. The Lever 20 in this case has two levers 21 and 22, which are on the one hand on the movable second ejection lever part 12 - also taken on the bolt 23 - are arranged and on the other hand movably disposed on the stationary parts 104 of the ejector 100. During the swinging out of the ejection lever 1 by the drive unit, the second ejection lever part 12 is pushed out by the lever mechanism 20 and thus causes the ejection lever 1 to increase its length during the ejection process.

Figuren 2a bis 2c zeigen in Draufsicht verschiedene Schwenkstellungen eines Ausstoßers 100 mit längenveränderlichem Ausstoßhebel 1, welcher während des Ausstoßvorganges seine Länge durch Verschiebung der beiden Ausstoßhebelteile 11 und 12 zueinander verändert. FIGS. 2a to 2c show in plan view various pivot positions of a pusher 100 with variable-length ejection lever 1, which changes its length during the ejection process by displacement of the two ejection lever parts 11 and 12 to each other.

Figur 2a zeigt einen eingeschwenkten Ausstoßhebel 1 des Ausstoßers 100. Der Ausstoßhebel 1 weist dabei einen ersten Ausstoßhebelteil 11 und einen dazu beweglichen zweiten Ausstoßhebelteil 12 auf. Das Hebelwerk 20, das einerseits an einem unbewegten Teil 104 des Ausstoßers 100 angeordnet ist und andererseits über den Bolzen 23 am zweiten Ausstoßhebelteil 12 angeordnet ist, ist Teil der Verstellvorrichtung 2. FIG. 2a shows a pivoted ejection lever 1 of the ejector 100. The ejection lever 1 in this case has a first ejection lever part 11 and a second ejection lever part 12 movable with respect thereto. The lever mechanism 20, which is arranged on the one hand on a stationary part 104 of the ejector 100 and on the other hand is arranged on the bolt 23 on the second ejection lever part 12, is part of the adjustment. 2

In Figur 2b ist der Ausstoßhebel 1 bereits teilweise durch die Antriebseinheit ausgeschwenkt. Durch das Hebelwerk 20 der Verstellvorrichtung 2 wurde der zweite Ausstoßhebelteil 12 des Ausstoßhebels 1 ausgefahren, was zu einer Längenveränderung des Ausstoßhebel 1 während des Ausstoßvorganges geführt hat. Verschoben wurde dieser zweite Ausstoßhebelteil 12 durch den Hebel 21 des Hebelwerkes 20, welcher am Bolzen 23 des zweiten Ausstoßhebelteils 12 und am unbewegten Teil 104 des Ausstoßers 100 angeordnet ist.In FIG. 2b the ejection lever 1 is already partially swung out by the drive unit. By the lever mechanism 20 of the adjusting device 2, the second ejection lever part 12 of the ejection lever 1 has been extended, which has led to a change in length of the ejection lever 1 during the ejection process. This second ejection lever part 12 has been displaced by the lever 21 of the lever mechanism 20, which is arranged on the pin 23 of the second ejection lever part 12 and on the non-moving part 104 of the ejector 100.

In Figur 2c ist ein im Wesentlichen vollständig ausgefahrener Ausstoßhebel 1 dargestellt, bei dem der zweite Ausstoßhebelteil 12 seine im Wesentlichen maximale Entfernung vom ersten Ausstoßhebelteil 11 erreicht hat.In Figure 2c a substantially fully extended ejection lever 1 is shown, in which the second ejection lever part 12 has reached its substantially maximum distance from the first ejection lever part 11.

Figur 3a zeigt eine perspektivische Darstellung einer Variante eines Ausstoßers 100 mit einem antreibbaren Ausstoßhebel 1, wobei der antreibbare Ausstoßhebel 1 sich in seiner Ausgangslage befindet, bei der noch keine Bewegung eines bewegbaren Möbelteils 102 (nicht dargestellt) erfolgen würde. FIG. 3a shows a perspective view of a variant of a pusher 100 with a drivable ejection lever 1, wherein the drivable ejection lever 1 in its initial position is at which no movement of a movable furniture part 102 (not shown) would take place.

Figur 3b zeigt eine perspektivische Darstellung eines Ausstoßers 100 mit einem längenveränderbaren Ausstoßhebel 1, wobei bereits eine Verschwenkung des Ausstoßhebels 1 durch einen Antrieb erfolgt ist. Durch die Verstellvorrichtung 2 - unter anderem bestehend aus dem Hebelwerk 20 - wird der zweite Ausstoßhebelteil 12 des Ausstoßhebels 1 teleskopisch aus dem ersten Ausstoßhebelteil 11 des Ausstoßhebels 1 ausgefahren. FIG. 3b shows a perspective view of an ejector 100 with a length-adjustable ejection lever 1, wherein already a pivoting of the ejection lever 1 is effected by a drive. By the adjusting device 2 - including consisting of the lever mechanism 20 - the second ejection lever part 12 of the ejection lever 1 is telescopically extended from the first ejection lever part 11 of the ejection lever 1.

Figur 3c zeigt den Ausstoßer 100, an dem der Ausstoßhebel 1 im Wesentlichen vollständig durch die Antriebseinheit ausgeschwenkt wurde. Während des Ausschwenkvorganges hat der Ausstoßhebel 1 seine Länge verändert - genauer genommen vergrößert - , indem der zweite Ausstoßhebelteil 12 durch die Verstellvorrichtung 2 bzw. dessen Hebelwerk 20 aus dem ersten Ausstoßhebelteil 11 teleskopisch ausgefahren wurde. Das Hebelwerk 20 - bestehend aus den beiden Hebeln 21 und 22 - ist einerseits am zweiten Ausstoßhebelteil 12 über den Bolzen 23 und andererseits an einem unbewegten Teil 104 des Ausstoßers 100 angelenkt. Figure 3c shows the ejector 100, on which the ejection lever 1 has been swung substantially completely by the drive unit. During the Ausschwenkvorganges the ejection lever 1 has changed its length - more precisely increased - by the second ejection lever part 12 was telescopically extended by the adjusting device 2 and its lever assembly 20 from the first ejection lever part 11. The lever mechanism 20 - consisting of the two levers 21 and 22 - is articulated on the one hand on the second ejection lever part 12 via the pin 23 and on the other hand on a non-moving part 104 of the ejector 100.

Die Verstellvorrichtung 2 bzw. dessen Hebelwerk 20 könnte natürlich auch so ausgebildet sein, dass während des Ausschwenkvorganges der Ausstoßhebel 1 seine Länge nicht vergrößert, sondern verkleinert. Wenn es zum Beispiel gewünscht werden sollte, dass das zu übertragende Drehmoment am Anfang geringer ist und am Ende des Ausschwenkvorganges hin größer ist. Weiters wäre es ebenso vorstellbar, eine Verstellvorrichtung 2 so zu konzipieren, dass die Längenveränderung des Ausstoßhebels 1 unterschiedlich verläuft, d.h. dass sich die Linie zum Beispiel anfänglich vergrößert und später wieder verkleinert oder umgekehrt. So es ohne Zweifel vorstellbar, dass sich die Längenveränderung des Ausstoßhebel 1 nach einem vorzugebenden Profil veränderbar ist.Of course, the adjusting device 2 or its lever mechanism 20 could also be designed such that during the swiveling out operation the ejection lever 1 does not increase its length, but reduces it. If, for example, it is desired that the torque to be transmitted is lower at the beginning and larger at the end of the swing-out process. Furthermore, it would also be conceivable to design an adjusting device 2 so that the change in length of the ejection lever 1 is different, i. for example, the line initially increases in size and then decreases again later, or vice versa. So it is undoubtedly conceivable that the change in length of the ejection lever 1 is variable according to a predetermined profile.

Figur 3d zeigt die Explosionsdarstellung des Ausstoßers 100 wie eben in den Figuren 3a bis 3c beschrieben. Die Teile des Ausstoßhebels 1 bestehen hier aus dem zweiten Ausstoßhebel 12, welcher teleskopisch im ersten Ausstoßhebelteil 11 gelagert ist. Dieser zweite Ausstoßhebelteil 12 ist dabei durch die Verstellvorrichtung 2 verstellbar. Dazu weist die Verstellvorrichtung 2 ein Hebelwerk 20 auf, dessen Hebel 21 und 22 über einen Bolzen 23 gelenkig am zweiten Ausstoßhebel 12 angeordnet sind. 3d figure shows the exploded view of the ejector 100 as just in the FIGS. 3a to 3c described. The parts of the ejection lever 1 consist here of the second ejection lever 12 which is mounted telescopically in the first ejection lever part 11. This second ejection lever part 12 is adjustable by the adjusting device 2. For this purpose, the adjusting device 2 has a lever mechanism 20, the levers 21 and 22 of which are articulated on the second ejection lever 12 via a pin 23.

Der zweite Ausstoßhebel 12 wird vom ersten Ausstoßhebel 11 geführt. Während des Ausstoßvorganges liegt der zweite Ausstoßhebelteil 12 sowohl im eingefahrenen Zustand während des Verfahrens als auch im ausgefahrenen Zustand am ersten Ausstoßhebelteil 11 des Ausstoßhebels 1 an.The second ejection lever 12 is guided by the first ejection lever 11. During the ejecting operation, the second ejection lever part 12 abuts the first ejection lever part 11 of the ejection lever 1 both in the retracted state during the process and in the extended state.

Die Figuren 4a bis 4c zeigen eine weitere Variante eines Ausstoßers 100 mit einem Ausstoßhebel 1, der seine Länge während des Ausstoßvorganges durch Verschiebung der beiden Ausstoßhebelteile 11 und 12 zueinander verändert.The FIGS. 4a to 4c show a further variant of an ejector 100 with an ejection lever 1, which changes its length during the ejection process by displacement of the two ejection lever parts 11 and 12 to each other.

Die Verstellvorrichtung 2, die diese Längenveränderung des Ausstoßhebels 1 bewirkt, ist dabei sowohl mit einem Hebelwerk 20 als auch einem Getriebe 30 ausgebildet.The adjusting device 2, which causes this change in length of the ejection lever 1, is formed both with a lever mechanism 20 and a gear 30.

In diesem speziellen Ausführungsbeispiel wird während des Ausschwenkvorganges die Länge des Ausstoßhebels 1 nicht nur vergrößert oder verkürzt, sondern am Anfang verfährt der Ausstoßhebelteil 12 während des Schwenkvorganges bis zu einem Winkel von etwa 120 Grad des Ausstoßhebels 1 nach Innen und anschließend erst verfährt - aufgrund der Ausbildung des Hebelwerkes 20 und dem damit zusammenspielenden Getriebe 30 -nach Außen und verlängert somit die Gesamtlänge des Ausstoßhebels 1, bis dieser seine maximale Länge bei ganz ausgefahrenem Ausstoßhebel 1 erreicht.In this particular embodiment, during the Ausschwenkvorganges the length of the ejection lever 1 is not only increased or shortened, but at the beginning of the ejection lever member 12 moves during the pivoting operation to an angle of about 120 degrees of the ejection lever 1 inside and then only moves - due to the training the lever mechanism 20 and the gear 30 cooperating therewith, to the outside, thus extending the total length of the ejection lever 1 until it reaches its maximum length with the ejection lever 1 completely extended.

Somit findet also anfänglich - während des Ausschenkvorganges des Ausstoßhebels 1 - keine Längenveränderung des Ausstoßhebels 1 statt. Erst ab einem vordefinierten Schwenkwinkel (in diesem Ausführungsbeispiel bei etwa 120 Grad) verändert der Ausstoßhebel 1 seine Länge durch die Verschiebung der beiden Ausstoßhebelteile 11 und 12 zueinander.Thus, therefore, initially - during the Ausschenkvorganges the ejection lever 1 - no change in length of the ejection lever 1 takes place. Only from a predefined pivoting angle (in this embodiment at about 120 degrees) of the ejection lever 1 changes its length by the displacement of the two ejection lever parts 11 and 12 to each other.

Figur 4a zeigt einen im Wesentlichen eingeschwenkten Ausstoßhebel 1 des Ausstoßers 100. Die Verstellvorrichtung 2 besteht in diesem Ausführungsbeispiel aus dem Hebelwerk 20 - welches die Hebel 41 und 42 aufweist - und dem Getriebe 30 - welches eine Zahnstange 31, ein Zahnrad 32 und ein Verstellelement 33 aufweist. Der Ausstoßhebeiteil 12 befindet sich noch gänzlich im Inneren des Ausstoßhebeiteils 11. FIG. 4a shows an essentially pivoted ejection lever 1 of the ejector 100. The adjusting device 2 consists in this embodiment of the lever mechanism 20 - which has the levers 41 and 42 - and the gear 30 - which has a rack 31, a gear 32 and an adjusting 33. The Ausstoßhebeiteil 12 is still entirely inside the Ausstoßhebeiteils 11th

Das Getriebe 30 befindet sich ebenfall im Inneren des Ausstoßhebels 1, was zu einer kompakten Ausbildung des Ausstoßers 100 beiträgt.The gear 30 is also located in the interior of the ejection lever 1, which contributes to a compact design of the ejector 100.

Während des Ausstoßvorganges wird nun bis zu einem Winkel von etwa 120 Grad der Ausstoßhebelteil 12 nach Innen bewegt (nicht dargestellt) und erst anschließend - nach dem Fortsetzen der Drehbewegung des Ausstoßhebels 1 - wird der Ausstoßhebelteil 12 durch die Verstellvorrichtung 2 (durch deren Hebelwerk 20 bzw. deren Getriebe 30) nach Außen geschoben und bewirkt somit eine Vergrößerung der Länge des Ausstoßhebels 1 (siehe Figur 4b).During the ejection process, the ejection lever part 12 is now moved inwards (not shown) up to an angle of approximately 120 degrees, and only after the rotary movement of the ejection lever 1 has continued, the ejection lever part 12 is moved by the adjusting device 2 (through the lever mechanism 20 thereof) whose transmission 30) pushed to the outside and thus causes an increase in the length of the ejection lever 1 (see FIG. 4b ).

Figur 4b und Figur 4c zeigen nun zwei verschiedene Schwenkstellungen des Ausstoßhebels 1 des Ausstoßers 100. Die Verschiebung der beiden Ausstoßhebelteile 11 und 12 zueinander erfolgte dabei über die Hebel 41 und 42 des Hebelwerkes 20, wobei der Hebel 41 gelenkig an einem unbewegten Teil 104 des Ausstoßers 100 angeordnet ist. Durch den Ausschwenkvorganges des Ausstoßhebels 1 wird über das Hebelwerk 20 und das Getriebe 30 die Zahnstange 31 durch das Zahnrad 32 verschoben und über das Verbindungselement 33 der zweite Ausstoßhebelteil 12 relativ zum ersten Ausstoßhebeiteil 11 verschoben. FIG. 4b and Figure 4c Now show two different pivot positions of the ejection lever 1 of the ejector 100. The displacement of the two ejection lever parts 11 and 12 to each other via the levers 41 and 42 of the lever mechanism 20, wherein the lever 41 is pivotally mounted on a stationary part 104 of the ejector 100. By the Ausschwenkvorganges the ejection lever 1, the rack 31 is displaced by the gear 32 via the lever mechanism 20 and the gear 30 and displaced via the connecting element 33 of the second ejection lever part 12 relative to the first Ausstoßhebeiteil 11.

Durch die Ausgestaltung des Hebelwerkes 20 und des Getriebes 30 ist es möglich, die Länge des Ausstoßhebels 1 nach beliebig vorzugebenden Kriterien während des Ausstoßvorganges sich verändern zu lassen.Due to the design of the lever mechanism 20 and the transmission 30, it is possible to change the length of the ejection lever 1 according to any predetermined criteria during the ejection process.

Ein hier nicht dargestellter Deckel - welcher am Ausstoßhebel 1 angeordnet wird - dient als Führung für das Zahnrad 32 und die Zahnstange 31 sowie auch als Eingriffschutz.A lid, not shown here - which is arranged on the ejection lever 1 - serves as a guide for the gear 32 and the rack 31 and also as an engagement protection.

Figur 5 zeigt eine perspektivische Ansicht eines Schnittes durch einen Möbelkorpus 101 mit einem Ausstoßer 100 und einer Ausziehführung 103, auf der ein bewegliches Möbelteil 102 (nicht dargestellt) anordenbar ist. Der Ausstoßhebel 1 des Ausstoßers 100 befindet sich in dieser Darstellung in seiner Ausgangsposition, bei der noch keine Bewegung eines beweglichen Möbelteils 102 erfolgen würde. FIG. 5 shows a perspective view of a section through a furniture body 101 with an ejector 100 and a pull-out 103, on which a movable furniture part 102 (not shown) can be arranged. The ejection lever 1 of the ejector 100 is in this representation in its initial position, in which no movement of a movable furniture part 102 would take place.

Figur 6 zeigt ein Möbel 110 mit einem Möbelkorpus 101, in dem eine Ausziehführung 103 angeordnet ist, auf der ein bewegliches Möbelteil 102 - in diesem Fall eine Schublade - angeordnet ist. Hinter dem beweglichen Möbelteil 102 ist der Ausstoßer 100 angeordnet, welcher über den längenveränderbaren Ausstoßhebel 1 die Schublade 102 ausstoßen kann. FIG. 6 shows a piece of furniture 110 with a furniture body 101, in which a pull-out guide 103 is arranged, on which a movable furniture part 102 - in this case a Drawer - is arranged. Behind the movable furniture part 102, the ejector 100 is arranged, which can eject the drawer 102 via the length-variable ejection lever 1.

Die Verstellvorrichtung 2 (nicht dargestellt) bewirkt dabei, dass sich die Länge des Ausstoßhebel 1 während des Ausstoßvorganges verändert, während der Ausstoßhebel 1 am bewegbar gelagerten Möbelteil 102 anliegt.The adjusting device 2 (not shown) thereby causes the length of the ejection lever 1 to change during the ejection process, while the ejection lever 1 rests against the movably mounted furniture part 102.

Wenn auch die Erfindung anhand des gezeigten Ausführungsbeispiels konkret beschrieben wurde, versteht es sich von selbst, dass der Anmeldungsgegenstand nicht auf dieses Ausführungsbeispiel beschränkt ist, vielmehr versteht es sich von selbst, dass Maßnahmen und Abwandlungen, innerhalb des Schutzumfangs der Ansprüchen, die dazu dienen, den Erfindungsgedanken umzusetzen, durchaus denkbar und erwünscht sind.Although the invention has been described concretely with reference to the illustrated embodiment, it goes without saying that the subject of the application is not limited to this embodiment, but it goes without saying that measures and modifications, within the scope of the claims, which serve implement the concept of the invention, quite conceivable and desirable.
