Description
Die vorliegende Erfindung betrifft eine Öffnungsvorrichtung nach dem Oberbegriff des Anspruches 1 sowie eine Öffnungs- und Schließvorrichtung für bewegbare Möbelteile, insbesondere Schubkästen.The present invention relates to an opening device according to the preamble of claim 1 and an opening and closing device for movable furniture parts, in particular drawers.
Es sind Öffnungsvorrichtungen für bewegbare Möbelteile bekannt, die über einen Ausstoßmechanismus ein bewegbares Möbelteil in Öffnungsrichtung bewegen (
Die
Diese Aufgabe wird mit einer Öffnungsvorrichtung mit den Merkmalen des Anspruches 1 gelöst.This object is achieved with an opening device having the features of claim 1.
Erfindungsgemäß ist der Ausstoßanschlag mit dem Ausstoßaktivator derart gekoppelt ist, dass sowohl Zugkräfte als auch Druckkräfte übertragbar sind. Dadurch können an dem Schlitten Rastmittel vorgesehen sein, die dann während eines Öffnungs- oder Schließvorganges verrastet werden können. Dadurch wird die Funktionssicherheit erhöht, da der Schlitten und die Rastmittel zwangsgeführt sind.According to the invention, the ejection stop is coupled to the ejection activator such that both tensile forces and compressive forces can be transmitted. As a result, locking means can be provided on the carriage, which can then be locked during an opening or closing operation. As a result, the reliability is increased because the carriage and the locking means are positively guided.
Erfindungsgemäß sind an dem Schlitten zwei voneinander beabstandete Anschläge vorgesehen, wobei ein erster Anschlag mit dem Mitnehmer in Ausstoßrichtung und ein zweiter Anschlag in Einzugsrichtung mit dem Mitnehmer koppelbar ist. Dadurch wird gewährleistet, dass die Ausstoßvorrichtung schon vor Erreichen der Schließposition durch den ersten Anschlag gespannt wird. Der in Einzugsrichtung wirksame Anschlag kann dabei federnd ausgebildet sein und in Öffnungsrichtung an dem Mitnehmer rastend vorbeibewegt werden. Der in Schließrichtung wirksame Anschlag gelangt außer Eingriff mit dem Mitnehmer, wenn dieser in einer gespannten und verriegelten Position ist, beispielsweise durch Verschwenken während des Bewegens entlang einer Führungsbahn mit einem abgewinkelten Endabschnitt.According to two spaced-apart stops are provided on the carriage, wherein a first stop with the driver in the ejection direction and a second stop in the feed direction coupled to the driver is. This ensures that the ejection device is clamped by the first stop before reaching the closed position. The effective in the direction of feed stop can be designed to be resilient and latching be moved past in the opening direction of the driver. The closing-effective stopper disengages from the driver when in a cocked and locked position, for example by pivoting while moving along a guideway having an angled end portion.
Gemäß einer weiteren Ausgestaltung ist an dem Ausstoßanschlag ein Magnet angeordnet, der mit einem metallisch feststehenden Aktivator koppelbar ist. Dadurch kann der Ausstoßanschlag nicht nur Druck- sondern auch Zugkräfte übertragen, insbesondere kann über eine Kopplung des Ausstoßanschlages an dem feststehenden Aktivator der Schlitten entlang einer Führungsbahn gezogen werden. Dies ermöglicht auf einfache Weise ein Entkoppeln des ersten Anschlages von dem Mitnehmer und ein Ineingriffbringen des zweiten Anschlages an dem Schlitten mit dem Mitnehmer.According to a further embodiment, a magnet is arranged on the ejection stop, which can be coupled with a metallically fixed activator. As a result, the ejection stop can transmit not only compressive but also tensile forces; in particular, the carriage can be pulled along a guideway via a coupling of the ejection stop to the stationary activator. This allows in a simple manner a decoupling of the first stop from the driver and an engagement of the second stop on the carriage with the driver.
Statt eines Magneten kann auch ein verschiebbarer Riegel an dem Schlitten gelagert sein, der bei einer Schließbewegung mit dem Aktivator gekoppelt und bei einer Öffnungsbewegung ab einer bestimmten Position von dem Aktivator entkoppelt wird.Instead of a magnet and a sliding latch can be mounted on the carriage, which is coupled in a closing movement with the activator and decoupled at an opening movement from a certain position of the activator.
Gemäß einer weiteren Ausgestaltung ist ein verschwenkbarer Hebel vorgesehen, der einen Anschlag für den Schlitten ausbildet, wobei mittels des Hebels der Mitnehmer aus der Endposition entriegelbar ist, um die Ausstoßvorrichtung zu aktivieren. Dadurch wird die Schließposition durch den verschwenkbaren Hebel vorgegeben. Dabei gewährleistet die Einzugsvorrichtung, dass die Schließposition erreicht wird und der Schlitten an dem Hebel anliegt, ohne dass der Benutzer das bewegbare Möbelteil exakt in die Schließposition bewegen muss.According to a further embodiment, a pivotable lever is provided which forms a stop for the carriage, wherein by means of the lever, the driver from the end position can be unlocked to activate the ejection device. As a result, the closing position is predetermined by the pivotable lever. The retraction device ensures that the closed position is reached and the carriage bears against the lever without the user having to move the movable furniture part exactly to the closed position.
Vorzugsweise ist in einer Schließposition der Schlitten durch die Einzugsvorrichtung in Schließrichtung gespannt und die Haltekräfte des Mitnehmers in der verriegelten Position sind größer als die Auslösekräfte durch den Hebel, an dem der Schlitten anliegt. Dadurch wird eine Verriegelung bzw. Verrastung des bewegbaren Möbelteils in der Schließposition erhalten, so dass das System stabil ist, wenn lediglich die Einzugsvorrichtung in der Schließposition wirksam ist und den Schlitten in Schließrichtung spannt.Preferably, in a closed position of the carriage is tensioned by the retraction device in the closing direction and the holding forces of the driver in the locked position are greater than the triggering forces by the lever to which the carriage rests. Thereby, a locking or latching of the movable furniture part is obtained in the closed position, so that the system is stable when only the retraction device in the closed position is effective and biases the carriage in the closing direction.
Vorzugsweise wird der Kraftspeicher der Ausstoßvorrichtung beim Schließen des bewegbaren Möbelteils gespannt, wobei der Weg zum Spannen des Kraftspeichers beabstandet von einer Schließposition angeordnet ist, beispielsweise in einem Abstand zwischen 2 bis 5 cm. Dadurch wird die Handhabung besonders vereinfacht, da der Benutzer das Möbelteil nicht mehr exakt am Möbelkorpus verriegeln muss. Dabei kann die Einzugsvorrichtung bei einem Schließvorgang am Ende des Spannweges des Kraftspeichers der Ausstoßvorrichtung aktiviert werden, damit die Wegstrecke zwischen dem Spannen der Ausstoßvorrichtung und der tatsächlichen Schließposition automatisch über die Einzugsvorrichtung zurückgelegt werden kann. Um harte Anschlaggeräusche zu vermeiden, kann die Einzugsvorrichtung auch gedämpft ausgebildet sein.Preferably, the force accumulator of the ejection device is tensioned when closing the movable furniture part, wherein the path for tensioning the energy accumulator spaced from a closed position is arranged, for example, at a distance between 2 to 5 cm. As a result, the handling is particularly simplified because the user does not have to lock the furniture part exactly on the furniture body. In this case, the collection device can be activated during a closing operation at the end of the clamping path of the energy storage of the ejection device, so that the distance between the clamping of the ejection device and the actual closing position can be automatically covered by the feed device. To avoid hard impact noise, the collection device can also be designed to be damped.
Vorzugsweise weist die Ausstoßvorrichtung zwei Führungsbahnen auf. Eine dient zur Führung des Mitnehmers und ist üblicherweise als Krückstockkurve ausgeführt, also eine lineare Führungsbahn mit einem abgewinkeltem Endabschnitt. Die weitere Führungsbahn dient zur Führung des Schlittens bzw. Mitnehmerschlittens und ist bevorzugt mit ohne abgewinkelten Abschnitt ausgeführt. Es ist auch möglich, drei Führungsbahnen an dem Gehäuse vorzusehen.Preferably, the ejection device has two guideways. One serves to guide the driver and is usually designed as Krückstockkurve, ie a linear guideway with an angled end portion. The further guideway is used to guide the carriage or driver carriage and is preferably designed with no angled section. It is also possible to provide three guideways on the housing.
Die Einzugsvorrichtung und Ausstoßvorrichtung sind vorzugsweise beabstandet voneinander am bewegbaren Möbelteil und/oder Möbelkorpus montiert. Dadurch können Bauräume besonders gut genutzt werden, beispielsweise kann das Gehäuse der Ausstoßvorrichtung an der Unterseite eines Schubkastens montiert sein, während die Einzugsvorrichtung in einer Seitenzarge eines Schubkastens aufgenommen ist.The collection device and ejection device are preferably mounted at a distance from one another on the movable furniture part and / or furniture body. As a result, installation spaces can be used particularly well, for example, the housing of the ejection device can be mounted on the underside of a drawer, while the collection device is accommodated in a side frame of a drawer.

An dem Gehäuse 20 ist eine zweite Führungsbahn 22 ausgebildet, an der ein Mitnehmer 26 der Ausstoßvorrichtung 6 verfahrbar ist. Der Mitnehmer 26 umfasst zwei Zapfen 27, die in die Führungsbahn 22 eingreifen und eine hervorstehende Spitze 28, die mit dem ersten Anschlag 17 oder zweiten Anschlag 18 in Eingriff gebracht werden kann. Die Führungsbahn 22 umfasst dabei einen abgewinkelten Endabschnitt, an dem der Mitnehmer 26 durch die Kraft einer Feder 29 verriegelbar ist. Die Feder 29 kann dabei auf dem vom Mitnehmer 26 abgewandten Ende an unterschiedlichen Positionen am Gehäuse 20 oder am Gehäuse 20 angeordneten Bauteilen festgelegt werden, um die Kraft der Feder 29 einstellen zu können.On the
An dem Gehäuse 20 ist ein Hebel 30 drehbar gelagert, der mit einer Achse 31 in einer Aufnahme an dem Gehäuse 20 eingreift. Zu beiden Seiten der Achse 31 weist der Hebel 30 Arme 32 und 33 auf. Der Arm 32 liegt in der Schließposition an dem zweiten Anschlag 18 an, während der Arm 33 des Hebels 30 an dem Mitnehmer 26 anliegt. Die als Zapfen ausgeführten Anschläge 34 und 35 dienen als Drehwegbegrenzer für den Hebel 30. Der Anschlag 35 bewirkt, dass der Hebel 30 nicht aus dem Einflussbereich des Mitnehmers 26 gelangen kann. Wiederum der Anschlag 34 bewirkt, dass der Hebel 30 nicht aus dem Einflussbereich des Anschlags 18 am Schlitten 15 gelangen kann. Die Anschläge 34 und 35 erhöhen somit die Funktionssicherheit der Ausstoßvorrichtung.On the

Durch die Kraft der Feder der Einzugsvorrichtung wirkt der Schlitten 15, der über den Ausstoßanschlag 10 an dem Aktivator 7 abgestützt ist und daher nicht weiter entlang der Führungsbahn 21 verfahren kann, auf den Arm 32 des Hebels 30.

Durch das Eindrücken der Frontblende 4 wurde der Hebel 30 durch den Anschlag 18 am Schlitten 15 im Uhrzeigersinn gedreht, so dass der Arm 33 des Hebels 30 den Mitnehmer 26 aus der verriegelten Endposition heraus bewegt. Dadurch kann der Mitnehmer 26 nun durch die Kraft der Feder 29 entlang der Führungsbahn 22 bewegt werden. Der Mitnehmer 26 steht in Eingriff mit dem ersten Anschlag 17 am Schlitten 15.By pressing the

In dieser Position kann nun das Schubelement 4 frei in Öffnungsrichtung bewegt werden, wobei sowohl die Ausstoßvorrichtung 6 als auch die Einzugsvorrichtung 40 außer Eingriff stehen und nur noch die Zugkraft des Magneten 11 am Aktivator 7 überwunden werden muss, wobei dazu üblicherweise die Trägheitskraft des Schubkastens 3 genügt.In this position, the

Dadurch kann die Öffnungs- und Schließvorrichtung an unterschiedliche Einsatzzwecke optimiert angepasst werden, denn es wird von den Benutzern als unangenehm empfunden, wenn zu hohe Auswerfkräfte und Spannkräfte erforderlich sind. Vielmehr soll ein leichtgängiges Öffnen und Schließen erreicht werden. Für schwere Schubelemente, beispielsweise Schiebetüren und breite Schubkästen, sind höhere Auswerfkräfte notwendig als für leichte Möbelteile. Insofern kann durch geeignete Wahl der wirksamen Federkraft der Ausstoßvorrichtung sowie des wirksamen Auswerfweges eine optimierte Anpassung für den jeweiligen Einsatzzweck vorgenommen werden.As a result, the opening and closing device can be adapted to different purposes optimized because it is perceived by the user as unpleasant when too high Auswerfkräfte and clamping forces are required. Rather, a smooth opening and closing should be achieved. For heavy push elements, such as sliding doors and wide drawers, higher Auswerfkräfte are necessary than for lightweight furniture parts. In this respect, by suitable choice of the effective spring force of the ejection device as well as the effective Auswerfweges an optimized adaptation for the respective application are made.
