Description

Die Erfindung betrifft eine verriegelbare Ausstoßvorrichtung für ein in oder an einem Möbel bewegbar geführtes Möbelteil, insbesondere Schublade oder Tür, mit einem von einer Feder federbelasteten Antriebselement zum Bewegen des bewegbaren Möbelteiles aus einer geschlossenen Endlage in eine Offenstellung, wobei das Antriebselement zur Kraftübertragung auf das bewegbare Möbelteil in einer Führungsbahn verschiebbar angeordnet ist.The invention relates to a lockable ejection device for a movably guided in or on a furniture furniture part, in particular drawer or door, with a spring-loaded by a spring drive element for moving the movable furniture part from a closed end position to an open position, wherein the drive element for transmitting power to the movable Furniture part is slidably disposed in a guideway.

Verriegelbare Ausstoßvorrichtungen für bewegbare Möbelteile sind in verschiedenen Ausführungen bekannt. Sie sind so ausgelegt, dass das Antriebselement zum Bewegen des bewegbaren Möbelteiles aus einer geschlossenen Endlage in eine Offenstellung in Folge der sich entspannenden Feder direkt auf das bewegbare Möbelteil wirkt oder mit einem mit dem bewegbaren Möbelteil gekoppelten Mitnehmer in Eingriff gebracht wird.Lockable ejection devices for movable furniture parts are known in various designs. They are designed so that the drive element acts to move the movable furniture part from a closed end position into an open position as a result of relaxing spring directly on the movable furniture part or is brought into engagement with a coupled with the movable furniture part driver.

Gattungsgemäße verriegelbare Ausstoßvorrichtungen sind dabei in der Regel derart ausgebildet, dass das Antriebselement gleichzeitig als Zuhalteelement zum Sichern des bewegbaren Möbelteiles in der geschlossenen Endlage ausgebildet ist. Dazu ist das Antriebselement in einer Führungsbahn verschiebbar geführt, die eine Rastmulde zum Arretieren des von der gespannten Feder beaufschlagten Antriebselementes in der geschlossenen Endlage des bewegbaren Möbelteiles aufweist.Generic lockable ejection devices are generally designed such that the drive element is simultaneously formed as a locking element for securing the movable furniture part in the closed end position. For this purpose, the drive element is guided displaceably in a guideway, which has a detent recess for locking the acted upon by the tensioned spring drive element in the closed end position of the movable furniture part.

Zum Ausstoßen des bewegbaren Möbelteiles wird nach dem bekannten Touch-Latch-Prinzip das bewegbare Möbelteil zuerst in eine in Schließrichtung des bewegbaren Möbelteiles hinter der geschlossenen Endlage liegenden Auslösestellung gebracht, wobei über einen Mitnehmer das Antriebs- bzw. Zuhalteelement in der Führungsbahn verschoben wird bis es die Rastmulde verlassen hat und sich in einem in Wirkrichtung der Feder verlaufenden Antriebsabschnitt befindet, das heißt, die Arretierung des bewegbaren Möbelteils aufgehoben ist. Aufgrund der sich entspannenden Feder wird dann das Antriebselement in Öffnungsrichtung des bewegbaren Möbelteiles bewegt und stößt das bewegbare Möbelteil über den Mitnehmer auf.To eject the movable furniture part, the movable furniture part is first brought into a lying in the closing direction of the movable furniture part behind the closed end position release position according to the known touch-latch principle, via a driver, the drive or locking element is moved in the guideway until it has left the detent recess and is located in a direction of action of the spring extending drive section, that is, the locking of the movable furniture part is repealed. Due to the spring relaxing the drive element is then moved in the opening direction of the movable furniture part and pushes the movable furniture part on the driver.

Beispielsweise ist aus der DE 101 62 573 A1 ein Touch-Latch-Beschlag für Möbel bekannt, bei der ein Verriegelungszapfen die Ausstoßvorrichtung in geschlossener Endlage hält. Nach Entriegelung dieses Zapfens kann nur über ein kompliziertes und aufwändiges Gestänge ein bewegbares Möbelteil über separate Auswerferstifte ausgeworfen werden.For example, is from the DE 101 62 573 A1 a touch-latch hardware for furniture known in which a locking pin holds the ejector in the closed position. After unlocking this pin, a movable furniture part can be ejected via separate ejector pins only on a complicated and elaborate linkage.

Die aus dem Stand der Technik bekannten verriegelbaren Ausstoßvorrichtungen erfordern neben einem großen Platzbedarf weiters eine genaue Abstimmung der Position des Mitnehmers in Bezug auf die Führungsbahn, um ein einfaches Schließen und Öffnen des bewegbaren Möbelteiles sicherzustellen.The known from the prior art lockable ejection devices in addition to a large footprint further require a precise vote of the position of the driver with respect to the guideway to ensure easy closing and opening of the movable furniture part.

Die Erfindung hat es sich daher zur Aufgabe gemacht, eine verriegelbare Ausstoßvorrichtung der Eingangs erwähnten Art zu schaffen, die in einfacher Weise das Spannen und Entspannen der Feder sowie das Arretieren des Antriebselementes bei gespannter Feder ermöglicht und zudem konstruktiv einfach ausgebildet ist.The invention has therefore taken on the task of creating a lockable ejection device of the type mentioned, which allows in a simple manner the tensioning and relaxing of the spring and the locking of the drive element with cocked spring and is also structurally simple.

Erfindungsgemäß wird diese Aufgabe gelöst, indem das Antriebselement einen Zapfen aufweist, der das Antriebselement in der Führungsbahn führt, wobei die Führungsbahn einen Verriegelungsabschnitt mit einer Rastmulde zum lösbaren Arretieren des Antriebselementes über den Zapfen in geschlossener Endlage des bewegbaren Möbelteils und einen Abschnitt, der als Anschlag für den Zapfen des Antriebselements beim Entspannen der Feder ausgebildet ist, aufweist, wobei durch den Zapfen des federbelasteten Antriebselementes und dessen Zusammenwirken mit dem Verriegelungsabschnitt und dem (Ausstoß-)Abschnitt der Führungsbahn das Möbelteil einerseits lösbar arretierbar und andererseits bewegbar ist. Dazu ist wenigstens ein Abschnitt gemäß einem bevorzugten Ausführungsbeispiel der Erfindung schräg zur Bewegungsrichtung des bewegbaren Möbelteiles angeordnet.According to the invention, this object is achieved in that the drive element has a pin which guides the drive element in the guideway, wherein the guideway has a locking portion with a detent recess for releasably locking the drive element via the pin in the closed end position of the movable furniture part and a portion which serves as a stop is designed for the pin of the drive element when relaxing the spring has, wherein the furniture part on the one hand releasably lockable and on the other hand is movable by the pin of the spring-loaded drive element and its interaction with the locking portion and the (ejection) section of the guide track. For this purpose, at least one section according to a preferred embodiment of the invention is arranged obliquely to the direction of movement of the movable furniture part.

Anders ausgedrückt, dient der wenigstens eine schräge Abschnitt als Anschlag für das Antriebselement bzw. als Widerlager für die Feder beim Spannen und/oder Entspannen derselben, wobei das Antriebselement aufgrund der Federkraft an eine Seitenwand des den Anschlag bildenden Abschnittes der Führungsbahn gezogen wird und aufgrund der in diesem Abschnitt schräg verlaufenden Führungsbahn an dieser entlang gleitet.In other words, the at least one inclined portion serves as a stop for the drive element or as an abutment for the spring during clamping and / or relaxing the same, wherein the drive element is pulled due to the spring force to a side wall of the stop forming portion of the guideway and due to slides in this section oblique guideway along this.

Gemäß einer bevorzugten Ausführungsform der erfindungsgemäßen Ausstoßvorrichtung weist die Führungsbahn mehrere schräg zur Bewegungsrichtung des bewegbaren Möbelteiles verlaufende Abschnitte auf, von denen ein erster Abschnitt als Anschlag für das Antriebselement beim Spannen der Feder und ein zweiter Abschnitt als Anschlag für das Antriebselement beim Entspannen der Feder ausgebildet ist.According to a preferred embodiment of the ejection device according to the invention, the guide track has a plurality of obliquely to the direction of movement of the movable furniture part sections, of which a first portion is designed as a stop for the drive element when tensioning the spring and a second portion as a stop for the drive element when relaxing the spring ,

Auf diese Weise wird erreicht, dass bei einer Ausstoßvorrichtung mit einem von einem Kraftspeicher, beispielsweise einer Feder oder einem Fluiddruckspeicher, beaufschlagten Antriebselement, das in einer Führungsbahn verschiebbar geführt ist, auf einen separaten, mit dem bewegbaren Möbelteil gekoppelten Mitnehmer zum Laden und/oder Entladen des Kraftspeichers verzichtet werden kann, da das Widerlager beim Laden und/oder Entladen des Kraftspeichers erfindungsgemäß von einem schrägen Abschnitt der Führungsbahn gebildet ist.In this way it is achieved that acted upon in a discharge device with one of a force storage device, such as a spring or a fluid pressure accumulator Drive element, which is guided displaceably in a guideway, can be dispensed with a separate, coupled to the movable furniture part driver for loading and / or unloading of the energy storage, since the abutment according to the invention during loading and / or unloading of the energy storage of an oblique portion of the guideway is formed.

Um sicherzustellen, dass die Feder auch bei einer geringen Bewegungsgeschwindigkeit des bewegbaren Möbelteiles gespannt wird, sieht eine weitere Ausführungsform der Erfindung vor, dass der erste Abschnitt zum Spannen der Feder mit der Bewegungsrichtung des bewegbaren Möbelteiles einen zwischen 30° und 80°, vorzugsweise zwischen 60° und 65°, liegenden Winkel einschließt, während der zweite Abschnitt mit der Bewegungsrichtung des bewegbaren Möbelteils in vorteilhafter Weise einen Winkel von etwa 90° einschließt.To ensure that the spring is tensioned even at a low speed of movement of the movable furniture part, provides a further embodiment of the invention that the first portion for tensioning the spring with the direction of movement of the movable furniture part between 30 ° and 80 °, preferably between 60 ° and 65 °, lying angle, while the second portion with the direction of movement of the movable furniture part advantageously includes an angle of about 90 °.

Die Sicherung des bewegbaren Möbelteiles in seiner geschlossenen Endlage nach dem Spannen der Feder erfolgt gemäß einer weiteren Ausführungsform der Erfindung, indem die Führungsbahn einen Verriegelungsabschnitt mit einer Rastmulde zum lösbaren Arretieren des Antriebselementes in geschlossener Endlage des bewegbaren Möbelteiles aufweist.The securing of the movable furniture part in its closed end position after tensioning the spring takes place according to a further embodiment of the invention by the guide track has a locking portion with a detent recess for releasably locking the drive element in the closed end position of the movable furniture part.

Dabei kann der Führungsabschnitt im Wesentlichen parallel oder normal zur Bewegungsrichtung des bewegbaren Möbelteiles verlaufen, lediglich die Rastmulde muss so angeordnet sein, dass sie das Antriebselement in Öffnungsrichtung des bewegbaren Möbelteiles arretiert.In this case, the guide portion may extend substantially parallel or normal to the direction of movement of the movable furniture part, only the detent recess must be arranged so that it locks the drive element in the opening direction of the movable furniture part.

Eine besonders einfache konstruktive Lösung ergibt sich gemäß einem weiteren Ausführungsbeispiel der Erfindung dann, wenn die Führungsbahn als Führungsnut ausgebildet ist. Um die Ausmaße der Ausstoßvorrichtung, insbesondere die Längserstreckung derselben, klein halten zu können, sieht ein bevorzugtes Ausführungsbeispiel der Erfindung vor, dass die Ausstoßvorrichtung zwei vorzugsweise linear gegeneinander bewegbare Teile aufweist, wobei das federbelastete Antriebselement im ersten Teil drehbar gelagert ist und in eine im zweiten Teil ausgebildete, vorzugsweise nutenförmige Führungsbahn eingereift, wobei es sich als günstig erwiesen hat, wenn die Führungsbahn eine Austritts-/Eintrittsöffnung zum Ein-/Austreten des Antriebselementes in der Ebene der Führungsbahn aufweist.A particularly simple constructive solution results according to a further embodiment of the invention, when the guide track is formed as a guide groove. In order to keep the dimensions of the ejection device, in particular the longitudinal extension thereof, small, a preferred embodiment of the invention provides that the ejection device has two preferably linearly mutually movable parts, wherein the spring-loaded drive element is rotatably mounted in the first part and in one in the second Part trained trained, preferably groove-shaped guideway, wherein it has proved to be advantageous when the guideway has an outlet / inlet opening for entry / exit of the drive element in the plane of the guideway.

Um sicherzustellen, dass das bewegbare Möbelteil beim Entspannen der Feder über das Antriebselement soweit aus dem Möbel herausbewegt wird, dass die in der Regel grifflose Frontblende zur Gänze gegenüber dem Möbelkorpus vorsteht, sieht eine weitere Ausführungsform der Erfindung vor, dass das Antriebselement zur Bewegungsrichtung des bewegbaren Möbels um einen Winkel größer 45°, vorzugsweise um 90°, drehbar im ersten Teil der Ausstoßvorrichtung gelagert ist.In order to ensure that the movable furniture part as far as moving out of the spring is moved out of the furniture via the drive element that the usually handle-less front panel completely protrudes from the furniture body, provides a further embodiment of the invention that the drive element to the direction of movement of the movable Furniture is mounted at an angle greater than 45 °, preferably by 90 °, rotatable in the first part of the ejection device.

Wenn das Antriebselement als Hebel ausgebildet ist, an dem ein zum Eingriff in die Führungsbahn des zweiten Teiles der Ausstoßvorrichtung ausgebildeter Zapfen vorzugsweise drehbar angeordnet ist, wird eine sichere und stabile Führung des Antriebselementes in der Führungsbahn gewährleistet.

Die Fig. 1a zeigt ein erstes Ausführungsbeispiel einer erfindungsgemäßen Ausstoßvorrichtung 1, die in einem zur Montage an einem nicht dargestellten Möbel ausgebildeten Führungssystem 14 integriert ist. Das Führungssystem 14 ist als Schubkastenauszugführung ausgebildet und weist eine am Möbelkorpus ortsfest anordenbare Korpusschiene 11 und eine unter Zwischenschaltung einer Mittelschiene 13 gegenüber der Korpusschiene 11 verschiebbar gelagerte Ladenschiene 12, die mit dem bewegbaren Möbel lösbar verbindbar ist, auf.The Fig. 1a shows a first embodiment of an ejection device 1 according to the invention, which is integrated in a trained for mounting on a furniture, not shown, guide system 14. The guide system 14 is designed as a drawer slide and has a fixedly arranged on the furniture body carcass rail 11 and a displaceable with the interposition of a middle rail 13 relative to the carcass rail 11 mounted rail 12, which is releasably connectable to the movable furniture, on.

Beim dargestellten Ausführungsbeispiel ist die Ausstoßvorrichtung 1 zweiteilig ausgebildet und weist zwei gegeneinander linear verschiebbare Teile 2, 3 auf, wobei der erste Teil 3 ortsfest an der Korpusschiene 11 angeordnet ist, während der zweite Teil 2 ortsfest an der Ladenschiene 12 angeordnet ist.In the illustrated embodiment, the ejection device 1 is formed in two parts and has two mutually linearly displaceable parts 2, 3, wherein the first part 3 is fixedly arranged on the carcass rail 11, while the second part 2 is fixedly arranged on the drawer rail 12.

Fig. 1b zeigt das Ausführungsbeispiel aus Fig. 1a mit einer Explosionsdarstellung der Ausstoßvorrichtung 1. Im ersten Teil 3 ist das Antriebselement 5 um eine zur Ebene des ersten Teiles 3 im Wesentlichen normale Achse A drehbar gelagert. Das Antriebselement 5 ist als Hebel ausgebildet, der an seinem dem Drehpunkt gegenüber liegenden Ende einen Zapfen 6 aufweist. Das Antriebselement 5 ist von einer im ersten Teil 3 der Ausstoßvorrichtung 1 festgelegten Feder 4 beaufschlagt und wird über den Zapfen 6 in der Führungsbahn 7 des ersten Teiles 3 geführt, wobei der Zapfen 6 durch die schlitzförmige Führungsbahn 7 hindurch tritt und mit seinem freien Ende in die im zweiten Teil 2 ausgebildete Führungsbahn 8 eingreift und diese verschiebbar geführt ist (Fig. 4). Fig. 1b shows the embodiment Fig. 1a with an exploded view of the ejection device 1. In the first part 3, the drive element 5 is rotatably supported about an axis A substantially normal to the plane of the first part 3. The drive element 5 is designed as a lever which has a pin 6 at its end opposite the pivot point. The drive element 5 is acted upon by a fixed in the first part 3 of the ejection device 1 spring 4 and is guided over the pin 6 in the guide track 7 of the first part 3, wherein the pin 6 passes through the slot-shaped guide track 7 and with its free end in the trained in the second part 2 guideway 8 engages and this is guided displaceably ( Fig. 4 ).

Neben der Führungsbahn 8 ist im zweiten Teil 2 der Ausstoßvorrichtung 1 und zwar im Bereich der Eintritts-/Austrittsöffnung 10 der Führungsbahn 8 eine Federzunge 9 ausgebildet.In addition to the guide track 8, a spring tongue 9 is formed in the second part 2 of the ejection device 1, specifically in the region of the inlet / outlet opening 10 of the guide track 8.

In den Fig. 2a bis 2d ist der zweite Teil 2 der Ausstoßvorrichtung 1 in einer Unteransicht gezeigt, wobei der zweite Teil 2 an der Ladenschiene 12 über Verbindungsmittel 16 in Aufnahmeöffnungen 15 der Ladenschiene 12 befestigt ist. Weiters ist in den Fig. 2a bis 2d schematisch der Zapfen 6 des Antriebselementes 5 in unterschiedlichen Stellungen des bewegbaren Möbelteiles und damit der Ausstoßvorrichtung 1 gezeigt.In the Fig. 2a to 2d the second part 2 of the ejection device 1 is shown in a bottom view, wherein the second part 2 is fixed to the drawer rail 12 via connecting means 16 in receiving openings 15 of the drawer rail 12. Furthermore, in the Fig. 2a to 2d schematically the pin 6 of the drive element 5 in different positions of the movable furniture part and thus the ejector 1 shown.

In der Fig. 2a befindet sich der Zapfen 6 des Antriebselementes 5 im Verriegelungsabschnitt B der Führungsbahn 8 und zwar in der Rastmulde 19, das heißt, das bewegbare Möbelteil befindet sich in seiner geschlossenen Endlage. Um den Ausstoßvorgang zu starten, wird das bewegbare Möbelteil vom Benutzer zunächst in eine in Schließrichtung SR hinter der geschlossenen Endlage befindlichen Auslösestellung gebracht, sodass der Zapfen 6 in der Führungsbahn 8 verschoben wird und die Rastmulde 19 verlässt, wodurch die Verriegelung des federbelasteten Antriebselementes 5 aufgehoben wird.In the Fig. 2a is the pin 6 of the drive element 5 in the locking portion B of the guide rail 8 and indeed in the detent recess 19, that is, the movable furniture part is in its closed end position. To start the ejection process, the movable furniture part is first brought by the user into a release position located in the closing direction SR behind the closed end position, so that the pin 6 is displaced in the guide track 8 and leaves the detent recess 19, whereby the locking of the spring-loaded drive element 5 repealed becomes.

In Fig. 2b befindet sich der Zapfen 6 des Antriebselementes 5 bereits im schrägen Abschnitt A' der Führungsbahn 8, der auch als Antriebsabschnitt bezeichnet werden kann. Aufgrund der sich entspannenden Feder 4 wird das Antriebselement 5 seitlich verschwenkt und nimmt, in dem es an der Seitenwand des schrägen Abschnitts A' der Führungsbahn 8 entlang gleitet, den zweiten Teil 2 der Ausstoßvorrichtung 1 in Öffnungsrichtung OR des bewegbaren Möbelteiles mit, wodurch das bewegbare Möbelteil von seiner in Fig. 2a dargestellten geschlossenen Endlage in eine Offenstellung gebracht wird.In Fig. 2b the pin 6 of the drive element 5 is already in the inclined section A 'of the guide track 8, which may also be referred to as a drive section. Due to the relaxing spring 4, the drive member 5 is pivoted laterally and, by sliding on the side wall of the inclined portion A 'of the guideway 8, takes along the second part 2 of the ejector 1 in the opening direction OR of the movable furniture part, whereby the movable Furniture part of his in Fig. 2a shown closed end position is brought into an open position.

Dem ersten schrägen Abschnitt A' der Führungsbahn 8 schließt sich ein zur Bewegungsrichtung SR, OR des bewegbaren Möbelteiles im Wesentlichen paralleler Abschnitt C an, der an seinem dem schrägen Abschnitt A' gegenüberliegenden Ende eine Eintritts-/Austrittsöffnung 10 für den Zapfen 6 des Antriebselementes 5 aufweist.The first oblique section A 'of the guide track 8 is followed by a section C which is essentially parallel to the movement direction SR, OR of the movable furniture part and has an entry / exit opening 10 for the journal 6 of the drive element 5 at its opposite end to the oblique section A' having.

Hat der Zapfen 6 des Antriebselementes 5 den schrägen Abschnitt A' der Führungsbahn 8 passiert, ist der Ausstoßvorgang beendet und das bewegbare Möbelteil kann manuell vom Benutzer in seine geöffnete Endlage bewegt werden, wobei der Zapfen 6 des Antriebselementes 5 im Abschnitt C der Führungsbahn 8 verschoben wird (Fig. 2c).If the pin 6 of the drive element 5 has passed the oblique section A 'of the guide track 8, the ejection process is ended and the movable furniture part can be manually moved by the user into its open end position, the pin 6 of the drive element 5 being displaced in the section C of the guide track 8 becomes ( Fig. 2c ).

Beim Schließen des bewegbaren Möbelteiles wird der Zapfen 6 von der Federzunge 9, die die im Endbereich des Abschnittes C ausgebildete Austrittsöffnung 10 verschließt, auf den ersten schrägen Abschnitt A der Führungsbahn 8 abgewiesen. Dazu ist die Federzunge 9 an ihrem freien Ende keilförmig ausgebildet. Beim weiteren Hineinbewegen des bewegbaren Möbelteiles in den Möbelkorpus (Fig. 2d) gleitet der Zapfen 6 an der Wandung des schrägen Abschnittes A entlang, wodurch die Feder 4 der Ausstoßvorrichtung 1 gespannt wird. Selbstverständlich könnte anstatt der Feder 4 auch ein anderer Kraftspeicher, beispielsweise ein Fluiddruckspeicher, verwendet werden.When closing the movable furniture part, the pin 6 is rejected by the spring tongue 9, which closes the outlet opening 10 formed in the end region of the section C, on the first inclined portion A of the guideway 8. For this purpose, the spring tongue 9 is on formed wedge-shaped at its free end. Upon further movement of the movable furniture part into the furniture body ( Fig. 2d ) slides the pin 6 along the wall of the inclined portion A along, whereby the spring 4 of the ejector 1 is tensioned. Of course, instead of the spring 4, another energy storage device, such as a fluid pressure accumulator, could be used.

Hat der Zapfen 6 den schrägen Abschnitt A der Führungsbahn 8 passiert, ist die Feder 4 gespannt bzw. der Kraftspeicher geladen. Der Zapfen 6 durchläuft dann den Verriegelungsabschnitt B der Führungsbahn 8 bis er in der Rastmulde 19 einrastet, wodurch das federbelastete Antriebselement 5 verriegelt wird.If the pin 6 has passed the oblique section A of the guide track 8, the spring 4 is tensioned or the force store is loaded. The pin 6 then passes through the locking portion B of the guide rail 8 until it engages in the detent recess 19, whereby the spring-loaded drive element 5 is locked.

Beim gezeigten Ausführungsbeispiel ist das Führungssystem 14, wie später näher erläutert wird, mit einer bedämpften Einzugsautomatik ausgestattet. Aus diesem Grund weist der Verriegelungsabschnitt B vor der Rastmulde 19 einen zur Bewegungsrichtung OR, SR des bewegbaren Möbelteiles im Wesentlichen parallelen Abschnitt auf, in dem, nach dem Spannen der Feder 4 am Ende des schrägen Abschnittes A, das bewegbare Möbelteil bei gespannter Feder 4 mittels der bedämpften Einzugsvorrichtung in seine geschlossene Endlage gebracht wird. Mit einer derartigen Ausbildung wird einerseits erreicht, dass das bewegbare Möbelteil auch dann in seine geschlossene Endlage bewegt wird, wenn der Benutzer das bewegbare Möbelteil nur geringfügig beschleunigt, während andererseits im Falle einer zu großen Beschleunigung des bewegbaren Möbelteiles durch den Benutzer ein Anschlagen des bewegbaren Möbelteiles am Möbelkorpus bzw. das sofortige Auslösen der Ausstoßvorrichtung mittels der bedämpften Einzugsvorrichtung verhindert wird.In the embodiment shown, the guide system 14, as will be explained later, equipped with a damped automatic retraction. For this reason, the locking portion B in front of the detent recess 19 a to the direction of movement OR, SR of the movable furniture part substantially parallel portion in which, after tensioning the spring 4 at the end of the oblique portion A, the movable furniture part with cocked spring 4 means the damped feeder is brought into its closed end position. With such a design on the one hand ensures that the movable furniture part is also moved to its closed end position when the user accelerates the movable furniture part only slightly, while on the other hand in case of excessive acceleration of the movable furniture part by the user striking the movable furniture part is prevented on the furniture body or the immediate triggering of the ejection device by means of the damped feed device.

In den Fig. 3a bis 3j sind unterschiedliche Lagepositionen der im Führungssystem 14 integrierten Ausstoßvorrichtung 1 während eines Öffnungs- und Schließvorganges eines bewegbaren Möbelteiles (nicht dargestellt) gezeigt. Dabei entspricht die Ausstoßvorrichtung 1 dem in den Fig. 1 a und 1 b dargestellten Ausführungsbeispiel.In the Fig. 3a to 3j are different positional positions of the integrated in the guide system 14 ejector 1 during an opening and closing operation of a movable furniture part (not shown) shown. In this case, the ejection device 1 corresponds to the in the Fig. 1 a and 1 b illustrated embodiment.

Im Unterschied zum ersten Ausführungsbeispiel weist das Führungssystem 14 des in den Fig. 5a bis 5d dargestellten Ausführungsbeispieles keine Einzugs- und Dämpfvorrichtung auf. Das Fehlen einer Einzugsvorrichtung bedingt, dass der schräg verlaufende Abschnitt A der Führungsbahn 8 unmittelbar bis zur Rastmulde 19 des Verriegelungsabschnittes B der Führungsbahn 8 reicht. Im Gegensatz zum vorbeschriebenen Ausführungsbeispiel verläuft der Verriegelungsabschnitt B bei diesem Ausführungsbeispiel im Wesentlichen in dieselbe Richtung wie der schräge Abschnitt A' der Führungsbahn, der auch als Antriebsabschnitt bezeichnet werden kann.Another embodiment of an ejection device 1 according to the invention is in the Fig. 5a to 5d shown. In contrast to the first embodiment, the guide system 14 of the in the Fig. 5a to 5d illustrated embodiment no retraction and damping device. The absence of a retraction device requires that the inclined portion A of the guideway 8 extends directly to the detent recess 19 of the locking portion B of the guideway 8. In contrast to the above-described embodiment, the locking portion B extends in this embodiment substantially in the same direction as the inclined portion A 'of the guide track, which may also be referred to as a drive section.

Ansonsten folgt dieses Ausführungsbeispiel demselben Funtionsprinzip wie das Ausführungsbeispiel nach den Fig. 1 bis 4, weshalb auf eine nochmalige Beschreibung verzichtet wird.Otherwise, this embodiment follows the same funtionsprinzip as the embodiment of the Fig. 1 to 4 , which is why a further description is omitted.
