Description

Die Erfindung betrifft eine verriegelbare Ausstoßvorrichtung für ein bewegbares Möbelteil, mit einem, das bewegbare Möbelteil in Öffnungsrichtung beaufschlagenden Ausstoßelement, einem Gehäuse und einem im oder am Gehäuse angeordneten Verriegelungselement, durch das zumindest in Schließstellung des bewegbaren Möbelteils der Weg des Ausstoßelements in Öffnungsrichtung versperrbar ist, wobei durch das Verriegelungselement das Ausstoßelement sowohl bei Überdrücken des bewegbaren Möbelteils von einer Schließstellung in Schließrichtung als auch beim Ziehen des bewegbaren Möbelteils von der Schließstellung in Öffnungsrichtung freigebbar ist. Zudem betrifft die Erfindung ein Möbel mit einer solchen verriegelbare Ausstoßvorrichtung.The invention relates to a lockable ejection device for a movable furniture part, with a, the movable furniture part in the opening direction acting ejection element, a housing and a housing arranged in or on the locking element, by at least in the closed position of the movable furniture part, the path of the ejection element in the opening direction is locked, wherein the ejection element can be released by the locking element both in overpressures of the movable furniture part from a closed position in the closing direction and when pulling the movable furniture part from the closed position in the opening direction. In addition, the invention relates to a piece of furniture with such a lockable ejection device.

Auf dem Gebiet der Möbelbeschläge sind schon seit vielen Jahren Ausstoßvorrichtungen bekannt, durch die ein bewegbares Möbelteil automatisch geöffnet wird. Der Benutzer muss nur auf das bewegbare Möbelteil drücken, sodass die Verriegelung aufgehoben wird und das bewegbare Möbelteil von einem Kraftspeicher ausgestoßen wird.In the field of furniture fittings discharge devices have been known for many years, by which a movable furniture part is opened automatically. The user only has to press on the movable furniture part, so that the lock is released and the movable furniture part is ejected from a power storage.

Eine gängige Variante zum Verriegeln der Ausstoßvorrichtung ist die Verriegelung über eine Herzkurve. Dabei ist ein mit dem Ausstoßelement verbundenes Rastelement in der Schließstellung in einer Mulde einer herzkurvenförmigen Kulissenbahn gehalten. Durch Drücken auf das bewegbare Möbelteil wird das Rastelement aus der Mulde bewegt, wodurch der Weg in einen Öffnungsabschnitt der herzkurvenförmigen Kulissenbahn frei ist.A common variant for locking the ejection device is the locking over a heart curve. In this case, a locking element connected to the ejection element is held in the closed position in a trough of a heart-shaped slide track. By pressing on the movable furniture part, the latching element is moved out of the trough, whereby the way is free in an opening portion of the heart-shaped slide track.

Ein Problem bei solchen verriegelbaren Ausstoßvorrichtungen mit herzkurvenförmiger Kulissenbahn besteht darin, dass diese nur durch Drücken geöffnet werden kann. Wenn aber am Möbelteil gezogen wird, kann kein Öffnen erfolgen, da das Rastelement nicht aus der Rastmulde der herzkurvenförmigen Kulissenbahn entweichen kann.A problem with such lockable ejectors with heart-shaped slide track is that it can only be opened by pressing. But if pulled on the furniture part, no opening can be done because the locking element can not escape from the detent recess of the heart-shaped slide track.

Um dieses Problem zu lösen, sind bereits zahlreiche Vorrichtungen bekannt, bei denen eine Entriegelung nicht nur durch Drücken sondern auch durch Ziehen erfolgt. Aus der EP 2 272 400 A1 , der JP 2007-009 507 , der US 7,374,261 und der JP 2008-208 684 gehen dazu Beispiele hervor, bei denen Teile der herzkurvenförmigen Kulissenbahn beim Ziehen gedreht bzw. verschwenkt werden, sodass auch ein Entriegeln beim Ziehen am Rastelement möglich ist.To solve this problem, many devices are already known in which an unlocking is done not only by pressing but also by pulling. From the EP 2 272 400 A1 , of the JP 2007-009 507 , of the US 7,374,261 and the JP 2008-208 684 Examples show this, in which parts of the heart-shaped cam track are turned or pivoted when pulling, so that unlocking when pulling the locking element is possible.

Aus der WO 2007/050737 A2 geht ein flexibler spreizbarer Kanal hervor, durch den beim Ziehen das Rastelement in Öffnungsrichtung austreten und somit die Entriegelung aufheben kann.From the WO 2007/050737 A2 goes out a flexible expandable channel through which the locking element emerge in the opening direction when pulling and thus can unlock the unlock.

Aus der ein älteres Recht bildenden, nicht vorveröffentlichten, österreichischen Anmeldung A 614/2011 geht eine verschiebbarer "Pfropfen" hervor, der die Rastmulde der herzkurvenförmigen Kulissenbahn bildet. Bei Ziehen am verriegelten Rastelement wird dieser "Pfropfen" gegen eine Feder bewegt und ein Überlastweg für das Rastelement freigegeben.From the old law forming, not pre-published, Austrian application A 614/2011 is a displaceable "plug" out, which forms the detent recess of the heart-shaped slide track. When pulling on the locked locking element of this "plug" is moved against a spring and released an overload path for the locking element.

Die Erfindung betrifft hinsichtlich der Ausstoßvorrichtung zudem, dass das Ausstoßelement sowohl beim Überdrücken des bewegbaren Möbelteils als auch beim Ziehen des bewegbaren Möbelteils durch eine Relativbewegung des Verriegelungselements zum Gehäuse entriegelbar ist. Zusätzlich betrifft die Erfindung eine Erfassungseinrichtung zum Erfassen der Stellung des bewegbaren Möbelteils und eine Übertragungsvorrichtung zum Übertragen der von der Erfassungseinrichtung erfassten Stellung des bewegbaren Möbelteils auf das Verriegelungselement, wobei das Verriegelungselement in Abhängigkeit der erfassten Stellung bewegbar ist, wodurch die Stellung des bewegbaren Möbelteils unkompliziert auf das Verriegelungselement weitergeleitet wird. Um auf einfache Art und Weise eine Umwandlung der Ziehbewegung und der Drückbewegung in ein und dieselbe Bewegung des Verriegelungselements zu ermöglichen, betrifft die Erfndung hinsichtlich der Ausstoßvorrichtung weiters, dass die Übertragungsvorrichtung ein Drehelement aufweist, das von zumindest einem Kraftspeicher in einer Mittellage haltbar ist.With regard to the ejection device, the invention also relates to the fact that the ejection element can be unlocked by a relative movement of the locking element to the housing both when the movable furniture part is over-pressed and when the movable furniture part is pulled. In addition, the invention relates to a detection device for detecting the position of the movable furniture part and a transmission device for transmitting the detected by the detection device position of the movable furniture part on the locking element, wherein the locking element is movable in response to the detected position, whereby the position of the movable furniture part uncomplicated the locking element is forwarded. In order to allow a simple way of converting the pulling movement and the pressing movement into one and the same movement of the locking element, the invention relates to the Ejection device further, that the transmission device comprises a rotary member which is durable by at least one energy storage in a central position.

Derartige Ausstoßvorrichtungen sind beispielsweise aus der WO 2009/114887 A1 und der EP 2 364 614 A2 bekannt.Such ejection devices are for example from the WO 2009/114887 A1 and the EP 2 364 614 A2 known.

Die Aufgabe der vorliegenden Erfindung besteht nun darin, eine gegenüber dem Stand der Technik alternative verriegelbare Ausstoßvorrichtung zu schaffen. Insbesondere soll es auf einfache Art und Weise ermöglicht werden, die Ausstoßvorrichtung sowohl beim Überdrücken als auch beim Ziehen zu entriegeln.The object of the present invention is therefore to provide an alternative to the prior art lockable ejection device. In particular, it should be possible in a simple manner to unlock the ejection device both when overpressing and when pulling.

Dies wird durch eine verriegelbare Ausstoßvorrichtung mit den Merkmalen von Anspruch 1 gelöst. Demnach ist erfindungsgemäß vorgesehen, dass die Erfassungseinrichtung über ein Angriffselement am Drehelement angreift, wobei sowohl bei Bewegung des Angriffselements in Öffnungsrichtung als auch in Schließrichtung das Drehelement aus der Mittellage drehbar ist. Bevorzugt ist bei außerhalb der Mittellage befindlichem Drehelement die Verriegelung des Ausstoßelements aufgehoben.This is achieved by a lockable ejection device having the features of claim 1. Accordingly, it is provided according to the invention that the detection device acts on an engagement element on the rotary element, wherein both upon movement of the engagement element in the opening direction and in the closing direction, the rotary member from the central position is rotatable. In the case of a rotary element located outside the central position, the locking of the ejection element is preferably canceled.

Der besondere Vorteil der Erfindung liegt darin, dass beim Überdrücken und beim Ziehen immer dieselbe Bewegung des Verriegelungselements erfolgt. Bei dem im Stand der Technik bekannten verriegelbaren Ausstoßvorrichtungen bildet immer die Rastmulde das Verriegelungselement. Diese Rastmulde wird aber bei der normalen Öffnungsbewegung durch Überdrücken nicht bewegt, nur beim Ziehen wird bei den Ausstoßvorrichtungen gemäß dem Stand der Technik eine Bewegung zumindest eines Teils der Rastmulde durchgeführt.The particular advantage of the invention is that always takes place during overpressing and pulling the same movement of the locking element. In the case of the lockable ejection devices known in the prior art, always the detent recess forms the locking element. However, this detent recess is not moved during the normal opening movement by overpressing, only when pulling a movement of at least a portion of the detent recess is performed in the ejection devices according to the prior art.

Die Erfassungseinrichtung muss nicht in jeder Stellung mit dem Verriegelungselement verbunden sein. Es kann vielmehr vorgesehen sein, dass die Erfassungseinrichtung in Schließstellung, in überdrückter Schließstellung und in, der Schließstellung zumindest unmittelbar vorgelagerter, Offenstellung des bewegbaren Möbelteils am bewegbaren Möbelteil anliegt oder mit dem bewegbaren Möbelteil verbunden ist.The detection device need not be connected in any position with the locking element. Rather, it may be provided that the detection device in the closed position, in overpressed closed position and in, the closed position at least immediately upstream, open position of the movable furniture part rests on the movable furniture part or is connected to the movable furniture part.

Für eine einfache Ausgestaltung der Ausstoßvorrichtung kann gemäß einem ersten Ausführungsbeispiel der vorliegenden Erfindung vorgesehen sein, dass das Drehelement gleichzeitig das Verriegelungselement ist. Im Speziellen ist dazu vorgesehen, dass das Verriegelungselement über zwei Bügel mit zwei, den Kraftspeicher bildenden Federn verbunden ist, wobei die Federn einerseits am Gehäuse befestigt sind und andererseits jeweils an einem Ende eines der beiden Bügel befestigt sind, wobei die Bügel, vorzugsweise über Führungselemente, in im Gehäuse ausgebildeten Langlöchern begrenzt bewegbar sind. Weiters kann dieses erste Ausführungsbeispiel vorsehen, dass die Drehbewegung des Verriegelungselement beim Entriegeln nur in eine Richtung, vorzugsweise im Uhrzeigersinn, erfolgt, wobei die Drehbewegung aufgrund der in den beiden Langlöchern über die Führungselemente geführten Bügel begrenzt ist.For a simple embodiment of the ejection device can be provided according to a first embodiment of the present invention, that the rotating element is also the locking element. In particular, it is provided that the locking element is connected via two brackets with two, the energy storage springs, wherein the springs are on the one hand attached to the housing and on the other hand respectively attached to one end of one of the two brackets, wherein the bracket, preferably via guide elements , are limitedly movable in formed in the housing slots. Furthermore, this first embodiment can provide that the rotational movement of the locking element when unlocking only in one direction, preferably in a clockwise direction, takes place, wherein the rotational movement is limited due to the guided in the two slots on the guide elements bracket.

Gemäß einem zweiten Ausführungsbeispiel der vorliegenden Erfindung kann vorgesehen sein, dass das Verriegelungselement und das Drehelement gesondert ausgebildet sind, wobei das Verriegelungselement vom Kraftspeicher beaufschlagt ist und am Drehelement anliegt. Um eine Übertragung der Bewegungsdetektierung auf das Verriegelungselement zu ermöglichen, kann dabei vorgesehen sein, dass das Verriegelungselement an einem v-förmigen Bereich des Drehelements anliegt, wobei sich das Drehelement dann in Mittellage befindet, wenn das Verriegelungselement am drehachsnächsten Punkt des v-förmigen Bereichs anliegt.According to a second embodiment of the present invention can be provided that the locking element and the rotary member are formed separately, wherein the locking element is acted upon by the force accumulator and rests on the rotary member. In order to enable transmission of the movement detection to the locking element, it can be provided that the locking element bears against a v-shaped region of the rotary element, wherein the rotary element is then in the central position, when the locking element rests on the drehachsnächsten point of the v-shaped area ,

Grundsätzlich muss in der Schließstellung nur garantiert sein, dass der Weg des Ausstoßelements in Öffnungsrichtung durch das Verriegelungselement versperrt ist. Dies kann beispielsweise über Reibung bzw. Verklemmung erfolgen. Bevorzugt ist vorgesehen, dass das Ausstoßelement in Schließstellung über ein mit dem Ausstoßelement verbundenes Rastelement formschlussartig am Verriegelungselement gehalten ist.In principle, it must only be guaranteed in the closed position that the path of the ejection element in the opening direction is blocked by the locking element. This can be done, for example, by friction or jamming respectively. It is preferably provided that the ejection element is held in the closed position via a locking element connected to the ejection element form-locking manner on the locking element.

Um eine einfache Freigabe des Öffnungsweges für das Ausstoßelement zu erreichen, ist bevorzugt vorgesehen, dass das Verriegelungselement sowohl bei Überdrücken des bewegbaren Möbelteils von einer Schließstellung in Schließrichtung als auch beim Ziehen des bewegbaren Möbelteils von der Schließstellung in Öffnungsrichtung quer zur Öffnungsrichtung bewegbar ist. Schutz wird auch begehrt für ein Möbel mit einem bewegbaren Möbelteil und einer erfindungsgemäßen verriegelbaren Ausstoßvorrichtung für das bewegbare Möbelteil.In order to achieve a simple release of the opening path for the ejection element, it is preferably provided that the locking element is movable transversely to the opening direction both in overpressures of the movable furniture part from a closed position in the closing direction and when pulling the movable furniture part from the closed position in the opening direction. Protection is also desired for a piece of furniture with a movable furniture part and a lockable ejection device according to the invention for the movable furniture part.

Fig. 1 zeigt ein Möbel 18, bestehend aus einem Möbelkorpus 20 und einem darin bewegbar gelagerten Möbelteil 2, wobei sich das Möbelteil 2 in Schließstellung SS befindet. Das bewegbare Möbelteil 2 ist über eine Ladenschiene 21 (gegebenenfalls auch über eine Mittelschiene) mit der Korpusschiene 22 verbunden. Die Korpusschiene 22 bildet gemäß dieser schematischen Darstellung auch das Gehäuse 4 der verriegelbaren Ausstoßvorrichtung 1. Diese Ausstoßvorrichtung 1 weist ein Ausstoßelement 3 auf, das von einem Ausstoßkraftspeicher 24 in Öffnungsrichtung OR beaufschlagt ist. In Fig. 1 ist dieser Ausstoßkraftspeicher 24 gespannt, da der Weg des Ausstoßelements 3 in Öffnungsrichtung OR durch das Verriegelungselement 5 blockiert ist. An der Ladenschiene 21 ist ein Mitnehmer 23 befestigt, mit dem das Verriegelungselement 5 über die Übertragungseinrichtung 7 zumindest zeitweise verbunden ist. Die Übertragungseinrichtung 7 weist einerseits die Erfassungseinrichtung 6 zum Erfassen der Position des Mitnehmers 23 und somit des bewegbaren Möbelteils 2 sowie das Drehelement 8 auf. Fig. 1 shows a furniture 18, consisting of a furniture body 20 and a movably mounted therein furniture part 2, wherein the furniture part 2 is in the closed position SS. The movable furniture part 2 is connected to the carcass rail 22 via a drawer rail 21 (possibly also via a middle rail). According to this schematic illustration, the carcass rail 22 also forms the housing 4 of the lockable ejection device 1. This ejection device 1 has an ejection element 3, which is acted upon by an ejection force accumulator 24 in the opening direction OR. In Fig. 1 this ejection force accumulator 24 is taut, since the path of the ejection element 3 in the opening direction OR is blocked by the locking element 5. At the drawer rail 21, a driver 23 is fixed, with which the locking element 5 is connected via the transmission device 7 at least temporarily. On the one hand, the transmission device 7 has the detection device 6 for detecting the position of the driver 23 and thus of the movable furniture part 2 as well as the rotary element 8.

Wenn gemäß Fig. 2 in Schließrichtung SR auf das bewegbare Möbelteil 2 gedrückt wird, gelangt das bewegbare Möbelteil 2 in die überdrückte Schließstellung ÜS. Mit dieser Bewegung wird auch der Mitnehmer 23 und die Erfassungseinrichtung 6 in Schließrichtung SR bewegt, sodass über das Drehelement 8 das Verriegelungselement 5 quer zur Bewegungsrichtung des bewegbaren Möbelteils 2 bewegt wird und den Weg für das Ausstoßelement 3 in Öffnungsrichtung OR freigibt.If according to Fig. 2 is pressed in the closing direction SR on the movable furniture part 2, the movable furniture part 2 enters the overpressed closed position ÜS. With this movement, the driver 23 and the detection device 6 is moved in the closing direction SR, so that via the rotary member 8, the locking element 5 is moved transversely to the direction of movement of the movable furniture part 2 and releases the path for the ejection element 3 in the opening direction OR.

In im Wesentlichen gleicher Art und Weise erfolgt gemäß Fig. 3 eine Entriegelung des Verriegelungselements 5 bei Ziehen am bewegbaren Möbelteil 2 in Öffnungsrichtung. Dadurch gelangt das bewegbare Möbelteil 2 in eine der Schließstellung SS in Öffnungsrichtung OR unmittelbar vorgelagerte Offenstellung ZS (Ziehstellung).In substantially the same way, according to Fig. 3 an unlocking of the locking element 5 when pulled on the movable Furniture part 2 in the opening direction. As a result, the movable furniture part 2 reaches an open position ZS (pulling position) immediately upstream of the closed position SS in the opening direction OR.

Sobald das Verriegelungselement 5 das Ausstoßelement 3 - sei es durch Drücken (siehe Fig. 2) oder durch Ziehen (siehe Fig. 3) - freigegeben hat, kann sich der Ausstoßkraftspeicher 24 gemäß Fig. 4 in Öffnungsrichtung OR bewegen und dabei das bewegbare Möbelteil 2 mitnehmen bzw. ausstoßen. Der Mitnehmer 23 kann dabei - wie an sich bekannt - durch Verschwenken der Erfassungseinrichtung 6 in einen Freilauf gelangen. Dadurch befindet sich das bewegbare Möbelteil 2 in Offenstellung OS.Once the locking element 5, the ejection element 3 - either by pressing (see Fig. 2 ) or by pulling (see Fig. 3 ) - has released, the ejection force memory 24 according to Fig. 4 Move OR in the opening direction while taking the movable furniture part 2 or eject. The driver 23 can - as known per se - get by pivoting the detection device 6 in a freewheel. As a result, the movable furniture part 2 is in the open position OS.

Ein erstes Ausführungsbeispiel der vorliegenden Erfindung ist in den Fig. 5 bis 13 gezeigt. In den Explosionsdarstellungen von Fig. 5 und Fig. 6 ist das Gehäuse 4 der Ausstoßvorrichtung 1 gezeigt, wobei entlang der Führungsbahnen 39 das Ausstoßelement 3 bewegbar ist. Dieses Ausstoßelement 3 steht über nicht dargestellte Mittel zumindest abschnittsweise mit dem bewegbaren Möbelteil 2 in Verbindung. Zwischen dem Ausstoßelement 3 und dem Gehäuse 4 ist das Basiselement 25 entlang der Führungsbahn 31 verschiebbar angeordnet. Am Basiselement 25 ist auch die Federführung 34 für den Ausstoßkraftspeicher 24 angeordnet. Die Federbasen für den Ausstoßkraftspeicher 24 bilden einerseits der dickere Endbereich der Federführung 34 und andererseits der Anschlag 33 am Ausstoßelement 3. Am Basiselement 25 ist durch einen Bolzen die Drehachse D für das Drehelement 8 angeordnet. Das Drehelement 8 bildet bei diesem ersten Ausführungsbeispiel gleichzeitig das Verriegelungselement 5, wobei im Verriegelungselement 5 der Verriegelungsbereich 37 für ein in Fig. 6 dargestelltes Rastelement 17 ausgebildet ist. Am Verriegelungselement 5 greifen die beiden Bügel 11 und 12 an. Der Bügel 11 greift über sein bolzenförmiges Ende in das Verbindungsloch 29 des Verriegelungselements 5 ein. Zudem ist der Bügel 11 über das Führungselement 26 im im Gehäuse 4 ausgebildeten Langloch 15 verschiebbar geführt. Der Bügel 11 ist weiters über die den Kraftspeicher 9 bildende Feder 13 am Anschlag 28 federbeaufschlagt abgestützt. Dieser Anschlag 28 ist über die Befestigungsbereiche 32 fest mit dem Gehäuse 4 verbunden. In gleicher Art und Weise ist der Bügel 12 über sein bolzenförmiges vorderes Ende im Verbindungsloch 30 des Verriegelungselements 5 gehalten. Weiters ist das Führungselement 27 des Bügels 12 im unteren Langloch 16 verschiebbar geführt. Zudem ist dieser Bügel 12 über die ebenfalls den Kraftspeicher 9 bildende Feder 14 federbeaufschlagt. Über das Verbindungsloch 46 ist das Drehelement 8 bzw. das Verriegelungselement 5 mit der bolzenförmigen Drehachse D des Basiselements 25 drehbar verbunden. In der Explosionsdarstellung von Fig. 6 ist zudem ersichtlich, dass am Basiselement 25 ein Führungssteg 36 ausgebildet ist, der in die Führungsbahn 31 im Gehäuse 4 eingreift. Der Führungssteg 36 ist dabei geringfügig kürzer als die Führungsbahn 31, sodass das Basiselement 25 die Überdrückbewegung und die Ziehbewegung mitmachen kann. Das Ausstoßelement 3 ist über den Anschlag 33 in der Federführungsbahn 35 des Gehäuses 4 begrenzt verschiebbar. Einerseits kann dabei das Ausstoßelement 3 in Öffnungsrichtung OR bis zum Anschlag 47 und andererseits in Schließrichtung SR bis zum vollständigen Spannen des Ausstoßkraftspeichers 24 bzw. bis zum Anschlag an der Federführung 34 bewegt werden.A first embodiment of the present invention is shown in FIGS Fig. 5 to 13 shown. In the exploded views of Fig. 5 and Fig. 6 the housing 4 of the ejection device 1 is shown, along the guide tracks 39, the ejection element 3 is movable. This ejection element 3 is connected via means, not shown, at least in sections with the movable furniture part 2 in connection. Between the ejection element 3 and the housing 4, the base member 25 along the guide track 31 is slidably disposed. On the base member 25 and the spring guide 34 is arranged for the ejection force accumulator 24. The spring bases for the ejection energy storage 24 form on the one hand the thicker end region of the spring guide 34 and on the other hand, the stop 33 on the ejection element 3. On the base member 25, the axis of rotation D is arranged for the rotary member 8 by a bolt. The rotary member 8 forms in this first embodiment simultaneously the locking element 5, wherein in the locking element 5 of the locking portion 37 for a in Fig. 6 illustrated latching element 17 is formed. On the locking element 5, the two brackets 11 and 12 engage. The bracket 11 engages over its bolt-shaped end in the connecting hole 29 of the locking element 5 a. In addition, the bracket 11 is slidably guided via the guide member 26 formed in the housing 4 slot 15. The bracket 11 is further on the power storage 9 forming the spring 13th supported on the stop 28 spring loading. This stop 28 is connected via the attachment portions 32 fixed to the housing 4. In the same way, the bracket 12 is held by its bolt-shaped front end in the connecting hole 30 of the locking element 5. Furthermore, the guide member 27 of the bracket 12 is slidably guided in the lower slot 16. In addition, this bracket 12 is spring-loaded via the force also memory 9 forming spring 14. About the connecting hole 46, the rotary member 8 and the locking member 5 is rotatably connected to the bolt-shaped axis of rotation D of the base member 25. In the exploded view of Fig. 6 is also apparent that on the base member 25, a guide web 36 is formed, which engages in the guide track 31 in the housing 4. The guide web 36 is slightly shorter than the guide track 31, so that the base member 25 can join the overpressure movement and the pulling movement. The ejection element 3 is limitedly displaceable over the stop 33 in the spring guide track 35 of the housing 4. On the one hand, the ejection element 3 can be moved in the opening direction OR up to the stop 47 and on the other hand in the closing direction SR until the ejection force accumulator 24 is fully tensioned or until it stops against the spring guide 34.

In Fig. 7 ist die Ausstoßvorrichtung 1 im zusammengebauten Zustand dargestellt, wobei der Anschlag 3 in die Federführungsbahn 35 ragt. Zudem ragen die beiden Führungselement 26, 27 in die korrespondierenden Langlöcher 15 und 16. Die gesamte verriegelbare Ausstoßvorrichtung 1 befindet sich in Schließstellung SS.In Fig. 7 the ejection device 1 is shown in the assembled state, wherein the stopper 3 projects into the spring guide track 35. In addition, the two guide element 26, 27 protrude into the corresponding elongated holes 15 and 16. The entire lockable ejection device 1 is in the closed position SS.

Dazu passend ist in Fig. 8 die verriegelbare Ausstoßvorrichtung 1 ebenfalls in der Schließstellung SS gezeigt. Da die beiden als Druckfedern ausgebildeten Federn 13 und 14 gleich stark ausgebildet sind, befindet sich auch das Verriegelungselement (= Drehelement 8) in der Mittellage M. Dabei schlägt das Führungselement 27 am rechten Ende des etwas nach links versetzten Langlochs 16 an und kann sich nicht weiter in Öffnungsrichtung OR bewegen. Da die Feder 13 gleich stark ist, verbleibt das Führungselement 26 am linken Ende des weiter nach rechts versetzten Langloches 15. Das am Ausstoßelement 3 angeordnete Rastelement 17 ist im Verriegelungsbereich 37 des Verriegelungselements 5 gehalten. Der Weg des Rastelements 17 in Öffnungsrichtung OR ist somit durch das Verriegelungselement 5 versperrt.This is fitting in Fig. 8 the lockable ejection device 1 also shown in the closed position SS. Since the two formed as compression springs springs 13 and 14 are equally strong, is also the locking element (= rotary member 8) in the middle position M. In this case, the guide member 27 beats at the right end of the slightly offset to the left Langloch 16 and can not move further in the opening direction OR. Since the spring 13 is equally strong, the guide member 26 remains at the left end of the further offset to the right elongated hole 15. The arranged on the ejection element 3 locking element 17 is held in the locking portion 37 of the locking element 5. The path of the locking element 17 in the opening direction OR is thus blocked by the locking element 5.

Wenn von dieser Schließstellung SS ausgehend in Schließrichtung SR auf das bewegbare Möbelteil 2 gedrückt wird, gelangt die verriegelbare Ausstoßvorrichtung 1 in die überdrückte Schließstellung ÜS gemäß Fig. 9. Dabei wird über eine nicht näher dargestellte Erfassungseinrichtung 6 die Stellung des bewegbaren Möbelteils 2 weitergegeben und das Ausstoßelement 3, welches zusammen mit dem durch das Rastelement 17 gebildete Angriffselement 10 die Übertragungsvorrichtung 7 bildet, bewegt das Verriegelungselement 5 relativ zum Gehäuse 4 nach links. Da sich der obere Bügel 11 aufgrund des links am Langloch 15 anschlagenden Führungselements 26 nicht weiter nach links bewegen kann, dreht sich das Drehelement 8 zwangsweise im Uhrzeigersinn, bis das Führungselement 27 des Bügels 12 sich gegen die Kraft der Feder 14 bis zum linken Anschlag des Langlochs 16 bewegt hat. Gleichzeitig bewegt sich auch die Drehachse D um die halbe Distanz relativ zum Gehäuse 4. Durch diese Drehung des Drehelements 8 verschwenkt sich auch der Verriegelungsbereich 37, wodurch das Rastelement 17 - das die Überdrückbewegung in das Verriegelungselement 5 eingeleitet hat - freigegeben und somit nicht mehr vom Verriegelungselement 5 versperrt ist.If, starting from this closed position SS in the closing direction SR, the movable furniture part 2 is pressed, the lockable ejection device 1 moves into the over-pressed closed position ÜS Fig. 9 , In this case, the position of the movable furniture part 2 is passed on a detection device 6, not shown, and the ejection element 3, which together with the locking element 17 formed by the engagement element 10 forms the transmission device 7, moves the locking element 5 relative to the housing 4 to the left. Since the upper bracket 11 can not move further to the left due to the left on the slot 15 abutting guide member 26, the rotary member 8 forcibly rotates clockwise until the guide member 27 of the bracket 12 against the force of the spring 14 to the left stop of Langloch's 16 moves. At the same time the axis of rotation D moves by half the distance relative to the housing 4. This rotation of the rotary member 8 also pivots the locking portion 37, whereby the locking element 17 - which has initiated the overpressure movement in the locking element 5 - released and thus no longer from Locking element 5 is locked.

Derselbe Entriegelungseffekt wird auch beim Ziehen am bewegbaren Möbelteil 2 gemäß Fig. 10 erzielt. Wenn am bewegbaren Möbelteil 2 gezogen wird, bewegt sich das Ausstoßelement 3 und mit diesem das Rastelement 17 in Öffnungsrichtung OR und gelangt in die der Schließstellung SS unmittelbar vorgelagerte Offenstellung ZS. Durch das Rastelement 17, welches gleichzeitig das Angriffselement 10 bildet, wird das Drehelement 8 nach rechts in Öffnungsrichtung OR bewegt. Der untere Bügel 12 kann aufgrund des am rechten Anschlag des Langlochs 16 befindlichen Führungselements 27 nicht weiter in Öffnungsrichtung OR bewegt werden. Dagegen kann der Bügel 11 mit seinem Führungselement 26 im oberen Langloch 15 weiter in Öffnungsrichtung OR bewegt werden, wodurch wiederum eine Drehbewegung des Verriegelungselements 5 bzw. Drehelements 8 um die Drehachse D im Uhrzeigersinn ausgelöst wird. Die Drehachse D bewegt sich in etwa halb so weit wie das Verbindungsloch 29 relativ zum Gehäuse 4 in Öffnungsrichtung OR, bis der Führungssteg 36 an einem Ende der Führungsbahn 31 anschlägt. Durch das Drehen des Verriegelungselements 5 im Uhrzeigersinn gelangt auch bei dieser Fig. 10 das Rastelement 17 außerhalb des Verriegelungsbereichs 37 des Verriegelungselements 5.The same Entriegelungseffekt is also when pulling the movable furniture part 2 according to Fig. 10 achieved. When pulling on the movable furniture part 2, the ejection element 3 and with this the latching element 17 moves in the opening direction OR and enters the open position ZS immediately upstream of the closed position SS. By the locking element 17, which simultaneously forms the engagement element 10, the rotary member 8 to the right in Opening direction OR moves. The lower bracket 12 can not be moved further in the opening direction OR due to the right stop of the elongated hole 16 guide member 27. In contrast, the bracket 11 can be moved with its guide member 26 in the upper slot 15 further in the opening direction OR, which in turn causes a rotational movement of the locking element 5 and rotary member 8 about the axis of rotation D in the clockwise direction. The axis of rotation D moves approximately half as far as the connecting hole 29 relative to the housing 4 in the opening direction OR, until the guide web 36 abuts against one end of the guide track 31. By turning the locking member 5 in a clockwise direction also arrives at this Fig. 10 the locking element 17 outside of the locking portion 37 of the locking element fifth

Durch dieses Entriegeln kann sich gemäß Fig. 11 der Ausstoßkraftspeicher 24 entspannen und bewegt das Ausstoßelement 3 und mit diesem über eine nicht gezeigte Verbindungsvorrichtung das bewegbare Möbelteil 2 in Öffnungsrichtung OR. Sobald das Rastelement 17 nicht mehr in Kontakt mit dem Verriegelungselement 5 ist, bewegt sich jeweils eine der Federn 13 oder 14 wieder in die Ausgangslage, sodass sich auch das Drehelement 8 wieder gegen den Uhrzeigersinn in die Ausgangslage bzw. Mittellage M gemäß Fig. 11 bewegt.This unlocking can according to Fig. 11 the ejection force accumulator 24 relaxes and moves the ejection element 3 and with this via a connecting device, not shown, the movable furniture part 2 in the opening direction OR. As soon as the latching element 17 is no longer in contact with the locking element 5, one of the springs 13 or 14 in each case moves back into the initial position, so that the rotary element 8 again moves counterclockwise into the starting position or middle position M according to FIG Fig. 11 emotional.

Gemäß Fig. 12 hat sich der Ausstoßkraftspeicher 24 weiter entspannt und es ist eine weitere Offenstellung OS der Ausstoßvorrichtung 1 bzw. des bewegbaren Möbelteils 2 erreicht.According to Fig. 12 the ejection force accumulator 24 has further relaxed and a further open position OS of the ejection device 1 or of the movable furniture part 2 has been reached.

Wenn das bewegbare Möbelteil 2 wieder geschlossen wird, wird über eine Bewegung des Ausstoßelements 3 in Schließrichtung SR wieder der Ausstoßkraftspeicher 24 gespannt. Im letzten Teil des Schließabschnitts (siehe Fig. 13) gelangt das Rastelement 17 dabei in Kontakt mit dem Verriegelungselement 5, beim weiteren Zubewegen drückt das Rastelement 17 auf die Anlaufschräge 38 und dreht das Verriegelungselement 5 so lange um die Drehachse D gegen die Kraft der Feder 14, bis das Rastelement 17 im Verriegelungsbereich 37 einschnappt bzw. verriegelt ist. Damit ist dann wieder die Ausgangsposition (Schließstellung SS) gemäß Fig. 8 erreicht.When the movable furniture part 2 is closed again, the ejection force accumulator 24 is tensioned via a movement of the ejection element 3 in the closing direction SR again. In the last part of the closing section (see Fig. 13 ), the locking element 17 thereby comes into contact with the locking element 5, upon further Zubewegen presses the locking element 17th on the run-on slope 38 and rotates the locking element 5 so long about the axis of rotation D against the force of the spring 14 until the locking element 17 is snapped or locked in the locking portion 37. This then again the starting position (closed position SS) according to Fig. 8 reached.

Die Fig. 14 bis 20 zeigen ein weiteres Ausführungsbeispiel der vorliegenden Erfindung, wobei das Drehelement 8 und das Verriegelungselement 5 als gesonderte Bauteile ausgeführt sind. Am Gehäuse 4 ist dabei wiederum entlang einer Führungsbahn 39 das Ausstoßelement 3 verschiebbar gelagert. Dieses Ausstoßelement 3 ist über einen verbreiterten Endbereich - der das Rastelement 17 bildet - vom Verriegelungselement 5 gehalten. Das Verriegelungselement 5 wiederum ist um die Drehachse X drehbar am Gehäuse 4 gelagert und von einem am Gehäuse 4 abgestützten Kraftspeicher 9 beaufschlagt. Zudem ist ein Drehelement 8 über die Drehachse D am Gehäuse 4 drehbar gelagert. Außerhalb des Drehpunkts dieses Drehelements 8 befindet sich das Angriffselement 10, mit welchem die Erfassungseinrichtung 6 verbunden ist. Die Erfassungseinrichtung 6, das Angriffselement 10 und das Drehelement 8 bilden gemeinsam die Übertragungseinrichtung 7 zum Übertragen der Stellung des bewegbaren Möbelteils 2 auf das Verriegelungselement 5. Im Speziellen wird diese Stellung über den V-förmigen Bereich V des Drehelements 8 an das Verriegelungselement 5 weitergegeben.The FIGS. 14 to 20 show a further embodiment of the present invention, wherein the rotary member 8 and the locking element 5 are designed as separate components. On the housing 4, in turn, the ejection element 3 is displaceably mounted along a guide track 39. This ejection element 3 is held by a locking end portion - which forms the locking element 17 - by the locking element 5. The locking element 5 in turn is rotatably mounted on the housing 4 about the axis of rotation X and acted upon by a force accumulator 9 supported on the housing 4. In addition, a rotary member 8 is rotatably supported on the housing 4 via the rotation axis D. Outside the fulcrum of this rotary element 8 is the engagement element 10, with which the detection device 6 is connected. The detection device 6, the engagement element 10 and the rotary element 8 together form the transmission device 7 for transmitting the position of the movable furniture part 2 on the locking element 5. Specifically, this position is passed through the V-shaped portion V of the rotary member 8 to the locking element 5.

Entsprechend ist in Fig. 16 die Schließstellung SS gezeigt, bei der das Verriegelungselement 5 am drehachsnächsten Punkt P des V-förmigen Bereichs V des Drehelements 8 anliegt und sich das Drehelement 8 somit in der Mittellage M befindet. Der Kraftspeicher 9 ist dabei zumindest etwas entspannt, sodass der Verriegelungsbereich 37 des Verriegelungselements 5 den Weg des Ausstoßelements 3 in Öffnungsrichtung OR versperrt. Dies wird durch das verbreiterte Ende des Ausstoßelements 3, welches somit das Rastelement 17 bildet, erreicht.Accordingly, in Fig. 16 the closed position SS shown, in which the locking element 5 abuts the drehachsnächsten point P of the V-shaped portion V of the rotary member 8 and the rotary member 8 is thus in the central position M. The energy storage 9 is at least somewhat relaxed, so that the locking portion 37 of the locking element 5 blocks the path of the ejection element 3 in the opening direction OR. This is achieved by the widened end of the ejection element 3, which thus forms the latching element 17.

Wenn nun gemäß Fig. 17 in Schließrichtung SR nach rechts auf das bewegbare Möbelteil 2 gedrückt wird, bewegt sich auch die Erfassungseinrichtung 6 und mit diesem das Angriffselement 10 nach rechts. Da das Angriffselement 10 exzentrisch am Drehelement 8 angreift, dreht sich dieses im Uhrzeigersinn, wodurch das Verriegelungselement 5 nicht mehr am drehachsnächsten Punkt P des V-förmigen Bereichs V anliegen kann und gegen die Kraft des Kraftspeichers 9 gegen den Uhrzeigersinn verschwenkt wird. Dadurch versperrt der Verriegelungsbereich 37 nicht mehr das Rastelement 17, wodurch das Ausstoßelement 3 freigegeben bzw. entriegelt ist.If now according to Fig. 17 in the closing direction SR is pressed to the right on the movable furniture part 2, and the detection means 6 moves and with this the engagement element 10 to the right. Since the engagement element 10 acts eccentrically on the rotary member 8, this rotates clockwise, whereby the locking element 5 can no longer abut the drehachsnächsten point P of the V-shaped portion V and is pivoted against the force of the energy accumulator 9 counterclockwise. As a result, the locking portion 37 no longer blocks the locking element 17, as a result of which the ejection element 3 is released or unlocked.

Auch beim Ziehen am bewegbaren Möbelteil 2 in Öffnungsrichtung OR bewegt sich die Erfassungseinrichtung 6 mitsamt dem Angriffselement 10 nach links in Öffnungsrichtung OR (siehe Fig. 18). Dadurch dreht sich das Drehelement 8 aus seiner Mittellage M gegen den Uhrzeigersinn heraus und das Verriegelungselement 5 liegt wiederum nicht mehr am drehachsnächsten Punkt P des V-förmigen Bereichs V an. Das Verriegelungselement 5 wird aber wiederum unter Spannen des Kraftspeichers 9 gegen den Uhrzeigersinn geschwenkt, wodurch wiederum das Ausstoßelement 3 freigegeben ist.Even when pulling on the movable furniture part 2 in the opening direction OR, the detection device 6 moves together with the engagement element 10 to the left in the opening direction OR (see Fig. 18 ). As a result, the rotary member 8 rotates out of its central position M counterclockwise and the locking member 5 is again no longer at the drehachsnächsten point P of the V-shaped portion V at. However, the locking element 5 is again pivoted under tensioning of the force accumulator 9 counterclockwise, which in turn the discharge element 3 is released.

Sobald die überdrückte Schließstellung ÜS (Fig. 17) oder die der Schließstellung SS unmittelbar vorgelagerte Offenstellung ZS (Fig. 18) erreicht ist, kann der in diesem Ausführungsbeispiel nicht dargestellte Ausstoßkraftspeicher 24 das Ausstoßelement 3 in Öffnungsrichtung OR bewegen, wie es in Fig. 19 gezeigt ist. Sobald das bewegbare Möbelteil 2 die Offenstellung OS erreicht oder sobald die Erfassungseinrichtung 6 frei ist, kann sich der Kraftspeicher 9 wieder entspannen und bewegt über das Verriegelungselement 5 das Drehelement 8 wieder in seine Mittellage M.As soon as the overfilled closed position ÜS ( Fig. 17 ) or the closed position SS immediately upstream open position ZS ( Fig. 18 ), the ejection force accumulator 24 not shown in this embodiment can move the ejection element 3 in the opening direction OR as shown in FIG Fig. 19 is shown. Once the movable furniture part 2 reaches the open position OS or as soon as the detection device 6 is free, the energy storage device 9 can relax again and moves over the locking element 5, the rotary member 8 again in its center position M.

Beim Schließen wird der nicht dargestellte Ausstoßkraftspeicher 24 wieder gespannt und das Ausstoßelement 3 in Schließrichtung SR gemäß Fig. 20 bewegt. Über die Anlaufschräge 38 verschwenkt das Ausstoßelement 3 kurz vor Erreichen der Schließstellung SS das Verriegelungselement 5 gegen die Kraft des Kraftspeichers 9. Sobald der dickste Punkt des Ausstoßelements 3 überwunden ist, wird das Rastelement 17 des Ausstoßelements 3 wieder vom Verriegelungsbereich 37 des Verriegelungselements 5 teilweise reibschlüssig und teilweise formschlüssig gehalten.When closing the ejection force accumulator 24, not shown, again tense and the ejection element 3 in the closing direction SR according to Fig. 20 emotional. About the run-up slope 38, the ejection element 3 pivots briefly As soon as the thickest point of the ejection element 3 has been overcome, the latching element 17 of the ejection element 3 is again held by the locking region 37 of the locking element 5 partially frictionally and partially positively.

Ein drittes Ausführungsbeispiel einer verriegelbaren Ausstoßvorrichtung 1 ist in den Fig. 21 bis 27 dargestellt. Gemäß den Fig. 21 und 22 weist diese Ausstoßvorrichtung 1 ein Gehäuse 4 auf, wobei in einer Führungsbahn 39 des Gehäuses 4 das Ausstoßelement 3 verschiebbar gelagert ist. Zwischen der am Gehäuse 4 ausgebildeten Federbasis 40 und der am Ausstoßelement 3 ausgebildeten Federbasis 41 ist der als Zugfeder ausgebildete Ausstoßkraftspeicher 24 eingespannt. Ein verbreitertes Ende des Ausstoßelements 3 bildet wiederum das Rastelement 17. Das Verriegelungselement 5 ist bei diesem dritten Ausführungsbeispiel nicht drehbar sondern verschiebbar in einer Bahn 48 des Gehäuses 4 gelagert. Am Ende dieser Bahn 48 ist das Verriegelungselement 5 von einem Kraftspeicher 9 (Druckfeder) beaufschlagt. Das Verriegelungselement 5 weist ein Langloch 45 auf. Am in Richtung Führungsbahn 39 weisenden Ende des Verriegelungselements 5 ist der Verriegelungsbereich 37 angeordnet. Im Gehäuse 4 ist eine Bolzenaufnahme 43 für den Bolzen 42 ausgebildet, wobei dieser Bolzen 42 gleichzeitig die Drehachse D für das Drehelement 8 bildet und durch das Langloch 45 hindurch ragt. Der Bolzen 42 ist über die Bolzenaufnahme 44 mit dem Drehelement 8 verbunden. Das Drehelement 8 weist zusätzlich einen V-förmigen Bereich V auf, an welchem das hintere Ende des Verriegelungselements 5 anliegt. Zudem ist im Drehelement 8 exzentrisch eine Ausnehmung vorgesehen, die das Angriffselement 10 für eine in diesem dritten Ausführungsbeispiel nicht näher gezeigte Übertragungseinrichtung 7 bildet.A third embodiment of a lockable ejection device 1 is in the Fig. 21 to 27 shown. According to the FIGS. 21 and 22 this ejection device 1, a housing 4, wherein in a guide track 39 of the housing 4, the ejection element 3 is slidably mounted. Between the spring base 40 formed on the housing 4 and the spring base 41 formed on the ejection element 3, the ejection force accumulator 24 designed as a tension spring is clamped. A widened end of the ejection element 3 in turn forms the latching element 17. The locking element 5 is not rotatable but slidably mounted in a web 48 of the housing 4 in this third embodiment. At the end of this path 48, the locking element 5 by a force accumulator 9 (compression spring) acted upon. The locking element 5 has a slot 45. At the end of the locking element 5 pointing in the direction of the guide track 39, the locking area 37 is arranged. In the housing 4, a bolt receptacle 43 is formed for the bolt 42, said bolt 42 simultaneously forms the axis of rotation D for the rotary member 8 and projects through the slot 45 therethrough. The bolt 42 is connected via the bolt receptacle 44 with the rotary member 8. The rotary element 8 additionally has a V-shaped region V, against which the rear end of the locking element 5 rests. In addition, a recess is eccentrically provided in the rotary member 8, which forms the engagement element 10 for a transmission device 7 not shown in detail in this third embodiment.

Gemäß Fig. 23 befindet sich die verriegelbare Ausstoßvorrichtung 1 in Schließstellung SS. Dabei ist der Kraftspeicher 9 im Wesentlichen entspannt und der Verriegelungsbereich 37 des Verriegelungselements 35 versperrt dem Ausstoßelement 3 den Weg in Öffnungsrichtung OR. Der als Zugfeder ausgebildete Ausstoßkraftspeicher 24 ist gespannt. Das Drehelement 8 befindet sich in der Mittellage M, wobei das hintere Ende des Verriegelungselements 5 am drehachsnächsten Punkt P des V-förmigen Bereichs V des Drehelements 8 anliegt.According to Fig. 23 The lockable ejection device 1 is in the closed position SS. In this case, the energy accumulator 9 is substantially relaxed and the locking region 37 of the locking element 35 blocks the ejection element 3 the path in the opening direction OR. Trained as a tension spring ejection force memory 24 is stretched. The rotary element 8 is located in the middle position M, wherein the rear end of the locking element 5 abuts against the next-axis point P of the V-shaped region V of the rotary element 8.

Sobald beim Überdrücken des bewegbaren Möbelteils 2 in Schließrichtung SR in die überdrückte Schließstellung ÜS das Angriffselement 10 über die nicht dargestellte Übertragungseinrichtung 7 auch in Schließrichtung SR bewegt wird, dreht sich das Drehelement 8 im Uhrzeigersinn um die Drehachse D, wodurch das hintere Ende des Verriegelungselements 5 gegen die Kraft des Kraftspeichers 9 nach hinten verschoben wird (siehe Fig. 24). Dies wird dadurch erreicht, dass das Drehelement 8 aus der Mittellage M herausbewegt wird und das hintere Ende des Verriegelungselements 5 somit nicht mehr am drehachsnächsten Punkt P anliegt. Gleichzeitig bewegt sich auch der Verriegelungsbereich 37 zurück und gibt den Weg für das Rastelement 17 und das Ausstoßelement 3 in Öffnungsrichtung OR frei.As soon as upon pressing the movable furniture part 2 in the closing direction SR in the overpressed closed position ÜS the engagement element 10 is moved via the not shown transfer device 7 in the closing direction SR, the rotary member 8 rotates clockwise about the rotation axis D, whereby the rear end of the locking element. 5 is moved backwards against the force of the energy accumulator 9 (see Fig. 24 ). This is achieved in that the rotary element 8 is moved out of the central position M and thus the rear end of the locking element 5 is no longer abutting the point of rotation P next point. At the same time, the locking area 37 moves back and releases the path for the locking element 17 and the ejection element 3 in the opening direction OR.

Auch beim Ziehen am bewegbaren Möbelteil 2 in Öffnungsrichtung OR bewegt sich das Angriffselement 10 in Öffnungsrichtung OR mit und dreht dadurch das Drehelement 8 in diesem Fall gegen den Uhrzeigersinn (siehe Fig. 25). Dadurch wird wiederum das Verriegelungselement 5 gegen die Kraft des Kraftspeichers 9 verschoben, wodurch der Verriegelungsbereich 37 das Rastelement 17 und somit das Ausstoßelement 3 freigibt.Even when pulling on the movable furniture part 2 in the opening direction OR, the engagement element 10 moves in the opening direction OR and thereby rotates the rotary member 8 in this case counterclockwise (see Fig. 25 ). As a result, in turn, the locking element 5 is displaced against the force of the force accumulator 9, whereby the locking portion 37, the locking element 17 and thus the ejection element 3 releases.

Durch diese Freigabe bzw. Entriegelung kann sich der Ausstoßkraftspeicher 24 entspannen und bewegt das Ausstoßelement 3 in Öffnungsrichtung OR in die Offenstellung OS gemäß Fig. 26. Sobald keine Kraft mehr auf das Angriffselement 10 wirkt, kann sich der Kraftspeicher 9 wieder entspannen und das Drehelement 8 gelangt in die Mittellage M.By this release or unlocking of the ejection force accumulator 24 can relax and moves the ejection element 3 in the opening direction OR in the open position according to OS Fig. 26 , As soon as there is no more power on it Attack element 10 acts, the energy storage 9 can relax again and the rotary member 8 enters the center position M.

Beim Schließen des bewegbaren Möbelteils 2 bewegt sich das Ausstoßelement 3 wieder am Verriegelungsbereich 37 des Verriegelungselements 5 über die Anlaufschräge 38 vorbei, wonach das Ausstoßelement 3 wiederum teilweise formschlüssig und teilweise reibschlüssig am Verriegelungsbereich 37 gehalten ist. Die Reibung zwischen dem Ausstoßelement 3 und dem Verriegelungsbereich 37 aufgrund des Ausstoßkraftspeichers 24 muss größer sein als die Federkraft des Kraftspeichers 9.When closing the movable furniture part 2, the ejection element 3 again moves past the locking region 37 of the locking element 5 via the starting bevel 38, after which the ejection element 3 is again held partially positively and partially frictionally engaged on the locking region 37. The friction between the ejection element 3 and the locking region 37 due to the ejection force memory 24 must be greater than the spring force of the energy accumulator. 9

Somit ist durch die vorliegende Erfindung eine zu den bisherigen verriegelbaren Ausstoßvorrichtungen 1 alternative Ausgestaltung des Verriegelungselements 5 gezeigt, wobei das Ausstoßelement 3 sowohl beim Überdrücken des bewegbaren Möbelteils 2 als auch beim Ziehen des bewegbaren Möbelteils 2 durch eine Relativbewegung des Verriegelungselements 5 zum Gehäuse 4 entriegelbar ist.Thus, by the present invention, an alternative to the previous lockable ejection devices 1 embodiment of the locking element 5 is shown, wherein the ejection element 3 is unlocked both when overpressing the movable furniture part 2 and when pulling the movable furniture part 2 by a relative movement of the locking element 5 to the housing 4 ,

Grundsätzlich sind natürlich Adaptierungen an der gesamten Vorrichtung bei Beibehaltung des Grundgedankens möglich. So kann z.B. die gesamte Ausstoßvorrichtung 1 auch am bewegbaren Möbelteil 2 angeordnet sein und sich an einem korpusfesten Mitnehmer 23 abstoßen.In principle, of course, adaptations to the entire device while maintaining the basic idea are possible. Thus, e.g. the entire ejection device 1 may also be arranged on the movable furniture part 2 and repel on a carrier 23 fixed to the body.

Prinzipiell ist auch möglich, dass zusätzlich zu dem Ausstoßelement 3 auch eine, vorzugsweise gedämpfte, Einziehvorrichtung vorgesehen ist, mit der das Möbelteil 2 sanft in Schließstellung SS eingezogen wird. Diese kann baulich in die gesamte Konstruktion integriert sein oder auch gesondert ausgebildet sein. Das Gehäuse 4 muss nicht als Einhausung verstanden werden, sondern kann vielmehr auch als eine reine Montageplatte ausgebildet sein, an der die wesentlichen Komponenten der verriegelbaren Ausstoßvorrichtung 1 angeordnet sind.In principle, it is also possible that, in addition to the ejection element 3, a preferably damped retraction device is provided with which the furniture part 2 is pulled in gently in the closed position SS. This can be structurally integrated into the entire construction or be designed separately. The housing 4 need not be understood as housing, but rather may be formed as a pure mounting plate on which the essential components of the lockable ejection device 1 are arranged.
