Es ist daher Aufgabe der vorliegenden Erfindung, eine Ausstoßvorrichtung für ein bewegbares Möbelteil zu schaffen, die eine Rücklaufsperre aufweist, die hohe Haltekräfte aufnehmen kann und einfach aufgebaut ist.It is therefore an object of the present invention to provide a discharge device for a movable furniture part, which has a backstop, which can accommodate high holding forces and is simple.
Diese Aufgabe wird mit einer Ausstoßvorrichtung mit den Merkmalen des Anspruches 1 gelöst.This object is achieved with an ejection device with the features of
Die erfindungsgemäße Ausstoßvorrichtung für ein bewegbares Möbelteil umfasst eine Rücklaufsperre, die eine Öffnungsbewegung des bewegbaren Möbelteils begrenzt, wenn das Spannen der Feder bei einer Schließbewegung des Möbelteils noch nicht abgeschlossen ist, wobei die Rücklaufsperre ein in einer Führungsbahn geführtes Ritzel aufweist, das bei einer Öffnungs- oder Schließbewegung in Eingriff mit einer Zahnstange steht und über ein Verriegelungselement festsetzbar ist. Dadurch erfolgt das Festsetzen über eine Verbindung des Ritzels bzw. eines Zahnrades und der Zahnstange, so dass hohe Haltekräfte bereitgestellt werden, was auch ein Rücklaufen eines schweren Schubkastens verhindert, ohne die Teile der Rücklaufsperre zu beschädigen. Zudem wird über den Eingriff des Ritzels an der Zahnstange gewährleistet, dass bei einem Loslassen des bewegbaren Möbelteils während des Spannvorganges ein vergleichsweise schnelles Festsetzen des bewegbaren Möbelteils erfolgt, wobei die Rücklaufsperre mit der Zahnstange und dem Ritzel einfach aufgebaut ist.The ejection device for a movable furniture part according to the invention comprises a backstop, which limits an opening movement of the movable furniture part when the tensioning of the spring is not completed in a closing movement of the furniture part, wherein the backstop in a Guide track guided pinion, which is in an opening or closing movement in engagement with a rack and can be fixed via a locking element. Thus, the setting is made via a compound of the pinion and a gear and the rack, so that high holding forces are provided, which also prevents a return of a heavy drawer, without damaging the parts of the backstop. In addition, it is ensured via the engagement of the pinion on the rack, that when releasing the movable furniture part during the clamping process, a comparatively fast setting of the movable furniture part is done, the backstop with the rack and pinion is simple.
Vorzugsweise ist das Ritzel in Öffnungs- oder Schließrichtung drehbar entlang der Zahnstange geführt. Dadurch kann das Ritzel zusammen mit einem Schlitten relativ zu einer Führungsbahn an einem Gehäuse bewegt werden, wobei der Eingriff des Ritzels an der Zahnstange für den Benutzer weder akustisch noch haptisch spürbar ist. Das Ritzel kann dabei verschiebbar an einem Schlitten gelagert sein, wobei auch das Verriegelungselement an dem verfahrbaren Schlitten angeordnet ist. Bei einem Abbrechen des Spannvorganges kann eine Relativbewegung des Schlittens relativ zu dem Ritzel erfolgen, um dieses in seiner Drehbewegung zu blockieren und somit die Rücklaufsperre zu aktivieren. Hierbei kann an dem Schlitten eine im Wesentlichen L-förmige Kurvenführung ausgebildet sein, die eine Bewegung des Ritzels in zwei unterschiedliche Richtungen, insbesondere rechtwinklig zueinander, ermöglicht, um das Ritzel bei einer Öffnungs- und Schließbewegung in unterschiedlichen Abschnitten einer Führungsbahn führen zu können. Zusätzlich kann das Ritzel dann relativ zu dem Schlitten für eine Festsetzbewegung verschoben werden.Preferably, the pinion is rotatably guided in the opening or closing direction along the rack. Thereby, the pinion can be moved together with a carriage relative to a guide track on a housing, wherein the engagement of the pinion on the rack for the user is neither acoustically nor tactile felt. The pinion can be slidably mounted on a carriage, wherein the locking element is arranged on the movable carriage. When canceling the clamping operation, a relative movement of the carriage relative to the pinion can be done to block this in its rotational movement and thus to activate the backstop. In this case, a substantially L-shaped cam guide may be formed on the carriage, which allows movement of the pinion in two different directions, in particular at right angles to each other, to be able to guide the pinion in an opening and closing movement in different sections of a guideway. In addition, the pinion can then be displaced relative to the carriage for a set movement.
Für eine stabile Festsetzung des Ritzels kann das Verriegelungselement als Zahnstangenabschnitt ausgebildet sein. Dadurch wird ein sicherer Eingriff bei einem Abbrechen des Spannvorganges zwischen Ritzel und Verriegelungselement bereitgestellt.For a stable fixing of the pinion, the locking element may be formed as a rack section. As a result, a secure engagement in a cancellation of the clamping operation between the pinion and the locking element is provided.
In einer Ausgestaltung ist eine an einem Gehäuse ausgebildete Führungsbahn für das Ritzel schlaufenförmig ausgebildet. Das Ritzel kann bei einer Bewegung des Möbelteils in Öffnungs- oder Schließrichtung entlang der Zahnstange bewegbar sein, während bei einer Schließ- oder Öffnungsbewegung das Ritzel in einem anderen Abschnitt der Führungsbahn geführt wird und somit beabstandet von der Zahnstange bewegbar ist.In one embodiment, a guideway formed on a housing for the pinion is formed loop-shaped. The pinion may be movable during a movement of the furniture part in the opening or closing direction along the rack, while in a closing or opening movement, the pinion is guided in another portion of the guide track and thus spaced from the rack is movable.
Vorzugsweise ist an der Führungsbahn für das Ritzel ein Rast- oder Halteabschnitt vorgesehen, an dem das Ritzel zur Verrastung der Feder in der Rastposition festsetzbar ist. Die Funktion der Verrastung der Feder und der Rücklaufsperre ist somit durch das Ritzel verwirklicht. Mit der Verrastung der Feder kann auch gleichzeitig das Möbelteil in der Schließposition verrastet werden. Alternativ ist es möglich, die Funktion der Rücklaufsperre und der Verrastung getrennt auszubilden. Hierfür kann an einem Gehäuse eine erste Führungsbahn für eine Achse des Ritzels und eine zweite Führungsbahn für ein Steuerelement eines Rastmechanismus zur Verrastung eines Schlittens an dem Gehäuse vorgesehen sein.Preferably, a latching or holding portion is provided on the guide track for the pinion on which the pinion for latching the spring in the latching position can be fixed. The function of locking the spring and the backstop is thus realized by the pinion. With the latching of the spring and the furniture part can be locked in the closed position at the same time. Alternatively, it is possible to form the function of the backstop and the latch separately. For this purpose, a first guide track for an axis of the pinion and a second guide track for a control of a latching mechanism for latching a carriage to the housing may be provided on a housing.
Vorzugsweise kann die Ausstoßvorrichtung mit einer Selbsteinzugsvorrichtung kombiniert werden, wie sie im Stand der Technik bekannt sind. Die Selbsteinzugsvorrichtungen können separat zur Ausstoßvorrichtung ausgeführt sein oder eine Einheit mit der Ausstoßvorrichtung bilden. Beim Schließen oder Öffnen des Schubkastens wird die Feder der Ausstoßvorrichtung gespannt und nach bzw. während dem Spannen und Verriegeln der Feder kann die Selbsteinzugsvorrichtung den Schubkasten in die Schließposition bewegen.Preferably, the ejection device may be combined with a self-closing device, as known in the art. The Selbsteinzugsvorrichtungen may be designed separately from the ejector or form a unit with the ejector. When closing or opening the drawer, the spring of the ejector is tensioned and after or during the tensioning and locking of the spring, the self-closing device can move the drawer to the closed position.
Vorzugsweise kann die Ausstoßvorrichtung verschiedene Ladeprinzipien für die mindestens eine Feder aufweisen. Das bedeutet, dass die mindestens eine Feder der Ausstoßvorrichtung nach dem Öffnen des bewegbaren Möbelteils beispielsweise beim Schließen geladen werden kann. Alternativ kann die Ausstoßvorrichtung das bewegbare Möbelteil in eine erste Öffnungsposition auswerfen, und dann kann der Benutzer das bewegbare Möbelteil manuell weiter in Öffnungsrichtung zu einer zweiten Öffnungsposition bewegen, beispielsweise bei einem Schubkasten. Dann kann diese Öffnungsbewegung von der ersten zur zweiten Öffnungsposition zum Spannen der mindestens einen Feder verwendet werden, so dass die Rücklaufsperre in diesem Fall während einer Öffnungsbewegung des bewegbaren Möbelteils wirksam werden kann.Preferably, the ejection device may have different charging principles for the at least one spring. This means that the at least one spring of the ejection device can be loaded after opening the movable furniture part, for example when closing. Alternatively, the ejector may eject the movable furniture member to a first open position, and then the user may manually move the movable furniture member further in the opening direction to a second open position, such as a drawer. Then, this opening movement can be used from the first to the second opening position for tensioning the at least one spring, so that the backstop in this case can be effective during an opening movement of the movable furniture part.
Erfindungsgemäß wird auch ein Möbel mit einem bewegbaren Möbelteil bereitgestellt, das über eine erfindungsgemäße Ausstoßvorrichtung in Öffnungsrichtung bewegbar ist. Das bewegbare Möbelteil ist vorzugsweise als linear bewegliches Möbelteil, insbesondere als Schubkasten oder Schiebetür, ausgebildet. Alternativ ist es möglich, die Ausstoßvorrichtung auch für Türen oder Klappen einzusetzen.According to the invention, a piece of furniture with a movable furniture part is provided, which is movable in the opening direction via an ejection device according to the invention. The movable furniture part is preferably designed as a linearly movable furniture part, in particular as a drawer or sliding door. Alternatively, it is possible to use the ejector for doors or flaps.

Ein Möbel 1 umfasst einen Möbelkorpus 2, in den ein bewegbares Möbelteil 3 in Form eines Schubkastens einfügbar ist, wobei eine Frontblende 4 an einer offenen Seite des Möbelkorpus 2 angeordnet ist. Der Schubkasten ist über zwei Auszugsführungen 5 verfahrbar gelagert, die an gegenüberliegenden Seitenwänden des Möbelkorpus 2 angeordnet sind. Jede Auszugsführung 5 ist in einer Seitenzarge 8 des Schubkastens über einen Haltewinkel 9 festgelegt und stützt über eine bewegbare Laufschiene den Schubkasten ab. Ferner sind an dem Möbelkorpus 2 winkelförmige Mitnehmer 7 fixiert, die mit einer Ausstoßvorrichtung 6 für das bewegbare Möbelteil 3 zusammenwirken. Über die Ausstoßvorrichtung 6 kann das bewegbare Möbelteil bei einem Eindrücken der Frontblende 4 in Schließrichtung zu dem Möbelkorpus 2 hin eine Entriegelung bewirken, um den Schubkasten dann in Öffnungsrichtung durch die Kraft mindestens einer Feder auszuwerfen. Wenn der Schubkasten in Schließrichtung bewegt wird, wird die mindestens eine Feder der Ausstoßvorrichtung 6 wieder gespannt.A piece of

Ferner ist an dem Gehäuse 10 eine schlaufenförmige Führungsbahn 12 für die Achse eines Ritzels 14 vorgesehen. Das Ritzel 14 ist verschiebbar an einem Schlitten 13 gehalten, der durch eine Feder 15 vorgespannt ist. Hierfür ist ein Ende 16 der Feder 15 an dem Schlitten 13 festgelegt, während ein zweites Ende 27 an dem Gehäuse 10 fixiert ist. Dadurch ist der Schlitten 13 in
An dem Schlitten 13 befindet sich ein Vorsprung 19, der an dem winkelförmigen Mitnehmer 7 abgestützt ist. Der Vorsprung 19 bildet ein Antriebselement aus, um das bewegbare Möbelteil nach einer Entriegelung aus der Rastposition in Öffnungsrichtung zu bewegen.On the
In der Rastposition ist das Ritzel 14 durch einen Rast- oder Halteabschnitt 22 an der Führungsbahn 12 bei gespannter Feder 15 gehalten. Wird das bewegbare Möbelteil 3 nun in Schließrichtung eingedrückt, bewegt sich das Gehäuse 10 relativ zu dem Schlitten 13, der durch den Vorsprung 19 an dem Mitnehmer 7 abgestützt ist. Dadurch wird eine Entriegelung der Verrastung bewirkt, und das Ritzel 14 bewegt sich von dem Rast- oder Halteabschnitt in die Führungsbahn 12, wie dies in
Nach der Entrastung kann nun der Schlitten 13 relativ zu dem Gehäuse bewegt werden, wobei das Ritzel 14 mit der Achse in einer ersten Führungsbahn 12A geführt ist, die in einem größeren Abstand von der Zahnstange 11 angeordnet ist als eine zweite Führungsbahn 12B. Bei einer Öffnungsbewegung des bewegbaren Möbelteils bewegt sich das Ritzel 14 in der ersten Führungsbahn 12A, wie dies in den
Bewegt sich das bewegbare Möbelteil 3 wieder in Schließrichtung, gelangt der Vorsprung 19 gegen den Mitnehmer 7 und bewegt den Schlitten 13 in
Wenn das bewegbare Möbelteil 3 weiter in Schließrichtung bewegt wird, verfährt der Schlitten 13 relativ zu dem Gehäuse 10, um die Feder 15 zu spannen. Wird nun das bewegbare Möbelteil 3 losgelassen, so dass das Spannen der Feder 15 abgebrochen wird, verhindert eine Rücklaufsperre das Ausstoßen des bewegbaren Möbelteils 3. Hierfür ist ein Verriegelungselement 17 an dem Schlitten ausgebildet, das als Zahnstangenabschnitt in Eingriff mit den Zähnen des Ritzels 14 bringbar ist. Wird der Spannvorgang unterbrochen, zieht die Feder 15 den Schlitten 13 in
Soll nun das bewegbare Möbelteil 3 weiter in die Schließposition bewegt werden, drückt der Benutzer das bewegbare Möbelteil gegen die Kraft der Feder 15 in Schließrichtung, so dass das Verriegelungselement 17 von dem Ritzel 14 wieder entfernt wird, so dass der Schlitten 13 mit dem Ritzel 14 weiter in Schließrichtung bewegt wird, wobei das Ritzel entlang der Führungsbahn 12B zu einem Rast- oder Halteabschnitt 22 bewegt wird, der an der Führungsbahn 12 ausgebildet ist. Bei Bedarf kann das Ritzel 14 erneut über das Verriegelungselement 17 festgesetzt werden. Bei jeder Verriegelung der Rücklaufsperre wird das Ritzel 14 an der L-förmigen Kurvenführung 18 verschoben.If now the
In der verrasteten Position des Ritzels 14 ist ein Schieber 20 in Eingriff mit der Achse des Ritzels 14, wobei an dem Schieber 20 eine Rastmulde 21 vorgesehen ist, die benachbart zu einem Halteabschnitt 22 an der Führungsbahn 12 positioniert ist. Durch eine Relativbewegung des Schiebers 20 zu dem Halteabschnitt 22 wird die Achse des Ritzels 14 freigegeben, das daraufhin wieder in die erste Führungsbahn 12A gelangen kann, um über die Ausstoßvorrichtung 6 eine Öffnungsbewegung zu bewirken. Der Schieber 20 ist über eine Feder 23 in die verrastete Position vorgespannt, so dass nach der Entriegelung eine erneute Verrastung des Ritzels 14 an dem Halteabschnitt 22 und der Rastmulde 21 stattfinden kann.In the latched position of the
Bei dem Ausführungsbeispiel der
An dem Gehäuse 10' ist zusätzlich zu der Führungsbahn 12' eine zweite Führungsbahn 30 ausgebildet, in die ein Steuerelement 31 eines Rastmechanismus geführt ist. Die Führungsbahn 30 ist schlaufenförmig bzw. als "Herzkurvenführung" ausgebildet, wobei an einem Ende eine Rastaufnahme 21' zur Fixierung des Steuerelementes 31 in einer Rastposition vorgesehen ist. Die Rastaufnahme 21' ist an einem Schieber 20' ausgebildet, der durch eine Feder 23 in die verrastete Position vorgespannt ist. Das Steuerelement 31 kann zwischen einem Halteabschnitt 22' und der Rastaufnahme 21' verrastet werden.On the housing 10 ', in addition to the guide track 12', a

Wenn die Ausstoßvorrichtung 6, 6' mit einer Selbsteinzugsvorrichtung kombiniert wird, kann die Feder 15 bereits vor Erreichen der Schließposition an dem Rast- oder Halteabschnitt 22, 22' mit gespannter Feder verrastet werden. Die Schließposition kann dann z.B. von der Selbsteinzugsvorrichtung oder einem anderen Element gehalten werden. Der Selbsteinzug kann zudem eine Schließbewegung des bewegbaren Möbelteils auch abbremsen. Grundsätzlich muss die Schließposition nicht von dem Rast- oder Halteabschnitt 22, 22' für die Feder 15 oder des Schlittens 13 vorgegeben sein.If the
