Description
Die Erfindung betrifft ein Möbel mit einem Möbelkorpus und einem im oder am Möbelkorpus bewegbar gelagerten Möbelteil sowie einer Ausstoßvorrichtung, die wenigstens ein Ausstoßelement zum Bewegen des bewegbaren Möbelteiles aus einer Schließstellung in eine erste Offenstellung und wenigstens eine verriegelbare Antriebsvorrichtung für das wenigstens eine Ausstoßelement aufweist, wobei Mittel zum Bewegen des wenigstens einen Ausstoßelementes über die erste Offenstellung hinaus vorgesehen sind. Weiters soll ein Verfahren zum Öffnen bzw. Schließen des neuartigen Möbels angegeben werden.The invention relates to a piece of furniture with a furniture body and a movably mounted in or on the furniture body furniture part and an ejection device having at least one ejection element for moving the movable furniture part from a closed position to a first open position and at least one lockable drive device for the at least one ejection element Means are provided for moving the at least one ejection element beyond the first open position addition. Furthermore, a method for opening or closing the novel furniture should be specified.
Derartige Möbel sind bereits bekannt (siehe z.B.
Die Erfindung hat es sich daher zur Aufgabe gemacht, ein verbessertes Möbel der in Rede stehenden Art anzugeben, mit dem die aus dem Stand der Technik bekannten Nachteile vermieden werden können. Dadurch soll ein Verfahren zum Öffnen bzw, Schließen des neuartigen Möbels angegeben werden.The invention has therefore set itself the task of providing an improved furniture of the type in question, with which the known from the prior art disadvantages can be avoided. This is intended to specify a method for opening or closing the novel piece of furniture.
Die Erfindung löst diese Aufgabe durch ein Möbel mit den Merkmalen von Anspruch 1.The invention solves this problem by a furniture with the features of claim 1.
Bei Antriebsvorrichtungen, die von einem manuell zu ladenden Kraftspeicher, vorzugsweise einer Zugfeder, gebildet sind, wird zum Laden des Kraftspeichers das vom Kraftspeicher beaufschlagte Ausstoßelement über eine Teilstrecke des Schließweges entweder mit dem bewegbaren Möbelteil oder dem Möbelkorpus, je nachdem, ob die Ausstoßvorrichtung am Möbelkorpus oder am bewegbaren Möbelteil angeordnet ist, gekoppelt. Bei den bisher bekannten gattungsgemäßen Ausstoßvorrichtungen erfolgt diese Koppelung im Wesentlichen in dem zwischen der geschlossenen Endlage und der ersten Offenstellung des bewegbaren Möbelteiles liegenden Abschnitt des Öffnungs- bzw. Schließweges des bewegbaren Möbels, wobei die erste Offenstellung des bewegbaren Möbelteiles der Stellung des Ausstoßelementes nach Beendigung des Ausstoßvorganges entspricht. Das bedeutet, dass der Benutzer das bewegbare Möbelteil beim Schließen desselben bis zum Erreichen der ersten Offenstellung scheinbar leicht bewegen kann, bevor er dann im letzten Abschnitt des Schließweges zusätzlich die Kraft zum Laden des Kraftspeichers aufbringen muss.In drive devices, which are formed by a manually loadable energy storage, preferably a tension spring, for loading the energy storage acted upon by the energy storage ejection element over a portion of the closing path either with the movable furniture part or the furniture body, depending on whether the ejection device on the furniture body or is arranged on the movable furniture part coupled. In the previously known generic ejection devices, this coupling takes place essentially in that between the closed end position and the first Open position of the movable furniture part lying portion of the opening or closing path of the movable furniture, wherein the first open position of the movable furniture part corresponds to the position of the ejection element after completion of the ejection process. This means that the user can apparently move the movable furniture part when closing it until it reaches the first open position before it then has to apply the force for loading the energy storage device in the last section of the closing path.
Hingegen wird beim erfindungsgemäßen Möbel dadurch, dass das Ausstoßelement nach Beendigung des Ausstoßvorganges über die erste Offenstellung des Möbelteiles hinaus bewegt wird, der Teilabschnitt des Schließweges, in dem das Ausstoßelement zum Laden des Kraftspeichers mit dem bewegbaren Möbelteil bzw. dem Möbelkorpus gekoppelt ist, in Richtung geöffneter Endstellung verlegt. Das bedeutet, dass der Benutzer unmittelbar nach bzw. gleichzeitig mit Beginn der Schließbewegung des bewegbaren Möbelteiles den Kraftspeicher der Antriebsvorrichtung zu laden beginnt und nach Beendigung des Ladevorganges nur mehr eine geringe Kraft aufbringen muss, um das bewegbare Möbelteile in seine geschlossene Endlage zu bewegen. Dadurch wird dem Benutzer der Eindruck einer insgesamt gleichmäßigeren Schließbewegung des bewegbaren Möbelteiles vermittelt.By contrast, in the furniture according to the invention in that the ejection element is moved beyond the first open position of the furniture part after completion of the ejection process, the portion of the closing path in which the ejection element is coupled to load the energy storage device with the movable furniture part or the furniture body in the direction moved open end position. This means that the user immediately after or simultaneously with the beginning of the closing movement of the movable furniture part begins to load the power storage of the drive device and after completion of the charging only a small force must apply to move the movable furniture parts in its closed end position. This gives the user the impression of an overall more uniform closing movement of the movable furniture part.
Gemäß einem ersten Ausführungsbeispiel der Erfindung sind die mit dem Ausstoßelement direkt oder indirekt gekoppelten bzw. koppelbaren Mittel zum Bewegen des wenigstens einen Ausstoßelementes über die erste Offenstellung hinaus am bewegbaren Möbelteil angeordnet, wobei es keine wesentliche Rolle spielt, ob das bewegbare Möbelteil von einer Tür, einer Klappe oder einer Schublade gebildet ist.According to a first exemplary embodiment of the invention, the means for directly or indirectly coupled or coupleable means for moving the at least one ejection element beyond the first open position are arranged on the movable furniture part, wherein it is irrelevant whether the movable furniture part depends on a door, a flap or a drawer is formed.
Eine einfache konstruktive Lösung sieht dabei vor, dass die Mittel wenigstens ein erstes am bewegbaren Möbelteil und wenigstens ein zweites im oder am Ausstoßelement angeordnetes Teil umfassen, wobei die beiden Teile derart ausgebildet und angeordnet sind, dass sie aufeinander eine magnetische Anziehungskraft ausüben. Selbstverständlich sind auch andere Lösungen denkbar. So könnte beispielsweise der erste Teil der Mittel von einer am bewegbaren Möbelteil drehgelenkig angeordneten Stange gebildet sein, und der zweite Teil der Mittel beispielsweise in Form einer Längsführung direkt am Ausstoßelement angeordnet sein.A simple design solution provides that the means comprise at least a first on the movable furniture part and at least a second arranged in or on the ejection member, wherein the two parts are formed and arranged so that they exert on each other a magnetic attraction. Of course, other solutions are conceivable. Thus, for example, the first part of the means could be formed by a rod arranged pivotably on the movable furniture part, and the second part of the means could be arranged, for example in the form of a longitudinal guide, directly on the ejection element.
Gemäß einer anderen Ausführungsform der Erfindung sind die mit dem Ausstoßelement direkt oder indirekt gekoppelten bzw. koppelbaren Mittel zum Bewegen des wenigstens einen Ausstoßelementes über die erste Offenstellung hinaus am Möbelkorpus und/oder in oder an der Ausstoßvorrichtung angeordnet, wobei ein bevorzugtes Ausführungsbeispiel der Erfindung vorsieht, dass die Ausstoßvorrichtung neben der Antriebsvorrichtung wenigstens einen zusätzlichen Hilfsantrieb aufweist, der das/die Mittel zum Bewegen des Ausstoßelementes beim CSffnen des bewegbaren Möbelteiles über die erste Offenstellung hinaus bildet.According to another embodiment of the invention, the means for directly or indirectly coupling or coupling means for moving the at least one ejection element beyond the first open position are arranged on the furniture body and / or in or on the ejection device, wherein a preferred embodiment of the invention provides the ejection device has, in addition to the drive device, at least one additional auxiliary drive which forms the means for moving the ejection element when the movable furniture part is opened beyond the first open position.
Eine konstruktiv einfache und trotzdem stabile Lösung ergibt sich dabei, wenn der Hilfsantrieb von einem vorzugsweise manuell zu ladenden Kraftspeicher, vorzugsweise einer Druckfeder, gebildet ist.A structurally simple and yet stable solution results when the auxiliary drive is formed by a preferably manually to be loaded energy storage, preferably a compression spring.
Obwohl es auch denkbar wäre, die Bewegung des Ausstoßelementes über die erste Offenstellung hinaus völlig unabhängig von der Bewegung des bewegbaren Möbelteiles zu gestalten, wird eine technisch einfache Lösung dann erreicht, wenn das wenigstens eine Ausstoßelement der Ausstoßvorrichtung in wenigstens einem zwischen der ersten Offenstellung und der geöffneten Endstellung liegenden Teilabschnitt des Öffnungs- bzw. Schließweges des bewegbaren Möbelteiles an diesem anliegt bzw. diesem folgt, wobei günstigerweise das wenigstens eine Ausstoßelement der Ausstoßvorrichtung über 50 %, vorzugsweise über 80 %, des Öffnung- bzw. Schließweges des bewegbaren Möbelteiles an diesem anliegt.Although it would also be conceivable to make the movement of the ejection element beyond the first open position completely independent of the movement of the movable furniture part, a technically simple solution is achieved if the at least one ejection element of the ejection device in at least one between the first open position and the open end position lying portion of the opening or closing path of the movable furniture part rests on this or follows this, wherein conveniently the at least one ejection element of the ejection device over 50%, preferably over 80%, of the opening or closing path of the movable furniture part rests against this ,
Gemäß einem alternativen Ausführungsbeispiel der Erfindung ist vorgesehen, dass die mit dem Ausstoßelement direkt oder indirekt gekoppelten bzw. koppelbaren Mittel zum Bewegen des wenigstens einen Ausstoßelementes über die erste Offenstellung hinaus am Möbelkorpus und/oder in oder an der Ausstoßvorrichtung angeordnet sind.According to an alternative embodiment of the invention, it is provided that the means for directly or indirectly coupled or coupleable means for moving the at least one ejection element beyond the first open position are arranged on the furniture body and / or in or on the ejection device.
Unabhängig davon, ob das Ausstoßelement translatorisch oder rotatorisch bewegbar am Möbelkorpus oder am bewegbaren Möbelteil angeordnet ist, sieht ein weiteres Ausführungsbeispiel der Erfindung vor, dass das Möbelteil im oder am Möbelkorpus translatorisch bewegbar, beispielsweise als Schublade ausgebildet, gelagert ist. Gemäß einem weiteren Ausführungsbeispiel kann das bewegbare Möbelteil aber auch im oder am Möbelkorpus rotatorisch bewegbar gelagert sein, wiederum unabhängig davon, ob das Ausstoßelement translatorisch oder rotatorisch bewegbar am Möbelkorpus oder am bewegbaren Möbelteil angeordnet ist.Regardless of whether the ejection element is arranged translationally or rotatably movable on the furniture body or on the movable furniture part, provides a further embodiment of the invention that the furniture part in or on the furniture body translationally movable, for example, designed as a drawer, is stored. According to a further embodiment, however, the movable furniture part can also be mounted rotatably movable in or on the furniture body, in turn, regardless of whether the Ejection element is arranged translationally or rotationally movable on the furniture body or on the movable furniture part.
Das heißt, die Erfindung eignet sich für alle denkbaren Kombinationen eines bewegbaren Möbelteiles mit einem Ausstoßelement, es muss nur sichergestellt werden, dass sich die Lage des Ausstoßelementes in Bezug auf seine Ausgangsstellung bei verriegelter Antriebsvorrichtung in der ersten Offenstellung, das ist nach Beendigung des Ausstoßvorganges, und zu Beginn des Ladevorganges verändert. Anders ausgedrückt müssen die Abstände zwischen dem Stoßpunkt des Ausstoßelement in Ausgangsstellung und dem Stoßpunkt in seiner Stellung nach Beendigung des Ausstoßvorganges einerseits und der Abstand zwischen dem Stoßpunkt des Ausstoßelement in Ausgangsstellung und dem Stoßpunkt in seiner Stellung nach Beendigung des Öffnungsvorganges andererseits verschieden sind.That is, the invention is suitable for all conceivable combinations of a movable furniture part with an ejection element, it must only be ensured that the position of the ejection element with respect to its initial position with locked drive device in the first open position, that is after completion of the ejection process, and changed at the beginning of the charging process. In other words, the distances between the impact point of the ejection element in the starting position and the impact point in its position after completion of the ejection process on the one hand and the distance between the impact point of the ejection element in the starting position and the impact point in its position after completion of the opening process on the other hand are different.
Ein bevorzugtes Ausführungsbeispiel ist durch ein drehbar gelagertes Ausstoßelement gekennzeichnet, wobei der Öffnungswinkel des Ausstoßelementes in seiner Stellung nach Beendigung des Ausstoßvorganges in der ersten Offenstellung des bewegbaren Möbelteiles einerseits, und der öffnungswinkel des Ausstoßelementes in seiner Stellung nach Beendigung des Öffnungsvorganges in der geöffneten Endlage des bewegbaren Möbelteiles andererseits, verschieden sind.A preferred embodiment is characterized by a rotatably mounted ejection element, wherein the opening angle of the ejection element in its position after completion of the ejection process in the first open position of the movable furniture part on the one hand, and the opening angle of the ejection element in its position after completion of the opening process in the open end position of the movable Furniture part, on the other hand, are different.
Ist das bewegbare Möbelteil ebenfalls drehbar gelagert, sind der maximale öffnungswinkel des Ausstoßelementes der maximale Öffnungswinkel des bewegbaren Möbelteiles günstigerweise annähernd gleich groß, wodurch das Ausstoßelement dem bewegbaren Möbelteil im Wesentlichen während des gesamten Öffnungsweges des bewegbaren Möbelteiles folgen kann.The movable furniture part is also rotatably mounted, the maximum opening angle of the ejection element, the maximum opening angle of the movable furniture part conveniently approximately the same size, whereby the ejection element can follow the movable furniture part substantially throughout the opening path of the movable furniture part.
Gemäß einer weiteren bevorzugten Ausführungsvariante der Erfindung ist vorgesehen, dass die Ausstoßvorrichtung zum zumindest teilweise Laden des Kraftspeichers der Antriebsvorrichtung für das Ausstoßelement während einer Schließbewegung des bewegbaren Möbelteils in einem zwischen der geöffneten Endstellung und der ersten Offenstellung liegenden Teilabschnitt des Öffnungs- bzw. Schließweges des bewegbaren Möbelteiles ausgebildet ist, wobei ein geräuscharmes und gleichmäßiges Schließen des bewegbaren Möbels dann erreicht wird, wenn die Ausstoßvorrichtung zum Starten des Ladevorganges des Kraftspeichers im Wesentlichen bei jeder Schließbewegung des bewegbaren Möbelteiles, vorzugsweise unabhängig von der Lage des bewegbaren Möbelteiles, ausgebildet ist.According to a further preferred embodiment of the invention, it is provided that the ejection device for at least partially loading the force accumulator of the drive device for the ejection element during a closing movement of the movable furniture part in a lying between the open end position and the first open position portion of the opening or closing path of the movable Furniture part is formed, wherein a silent and uniform closing of the movable furniture is achieved when the ejection device for starting the charging of the Power accumulator substantially at each closing movement of the movable furniture part, preferably independent of the position of the movable furniture part is formed.
Ist dabei das Ausstoßelement rotatorisch bewegbar gelagert, kann weiters vorgesehen sein, dass der öffnungswinkel des Ausstoßelementes nach Beendigung des Ausstoßvorganges in der ersten Offenstellung des bewegbaren Möbelteiles einerseits und zu Beginn des Ladevorganges des Kraftspeichers andererseits bzw. der Abstand zwischen dem Stoßpunkt des Ausstoßelementes in Ausgangsstellung und dem Stoßpunkt nach Beendigung des Ausstoßvorganges einerseits und der Abstand zwischen dem Stoßpunkt des Ausstoßelementes in Ausgangsstellung und dem Stoßpunkt zu Beginn des Ladevorganges des Kraftspeichers andererseits verschieden sind.If in this case the ejection element rotatably mounted, it may further be provided that the opening angle of the ejection element after completion of the ejection process in the first open position of the movable furniture part on the one hand and at the beginning of the charging process of the energy accumulator on the other hand or the distance between the shock point of the ejection element in the starting position and the impact point after completion of the ejection process on the one hand and the distance between the impact point of the ejection element in the starting position and the shock point at the beginning of the charging process of the energy storage on the other hand are different.
Gemäß einem bevorzugten Ausführungsbeispiel der Erfindung weist die Ausstoßvorrichtung ein drehbar gelagertes Ausstoßelement und eine verriegelbare Antriebsvorrichtung, vorzugsweise eine Schraubenzugfeder auf, die über ein Getriebe, vorzugsweise ein Zahnradgetriebe, miteinander wirkverbunden sind. In einfacher Weise kann dazu das Ausstoßelement mit der Antriebsvorrichtung über ein Koppelelement verbunden sein und einen zahnradförmig ausgebildeten Abschnitt aufweisen, der zum Eingriff mit einem Antriebsritzel, das in einem drehbar angeordneten Lagerelement gelagert ist, ausgebildet sein. Eine Platz sparende Lösung ergibt sich dabei, wenn wenigstens das Ausstoßelement, das Lagerelement für das Antriebsritzel und das Koppelelement koaxial angeordnet sind.According to a preferred embodiment of the invention, the ejection device comprises a rotatably mounted ejection element and a lockable drive device, preferably a helical tension spring, which are operatively connected to each other via a transmission, preferably a gear transmission. In a simple manner, for this purpose, the ejection element can be connected to the drive device via a coupling element and have a gear-shaped section, which is designed to engage with a drive pinion, which is mounted in a rotatably mounted bearing element. A space-saving solution results when at least the ejection element, the bearing element for the drive pinion and the coupling element are arranged coaxially.
Die Verriegelung der Antriebsvorrichtung kann beispielsweise mittels einer Klinke oder eines in einer beispielsweise herzförmigen Kulissenbahn geführten Mitnehmers oder, wie gemäß einem weiteren Ausführungsbeispiel der Erfindung vorgesehen, über einen Kniehebel und/oder einen Totpunktmechanismus erfolgen.The locking of the drive device, for example, by means of a pawl or guided in an example heart-shaped slide track driver or, as provided according to a further embodiment of the invention, via a toggle and / or a dead center.
Der zwischen dem Antriebsritzel und dem Koppelelement notwendige Freilauf zum Bewegen des Ausstoßelementes über die erste Offenstellung hinaus wird gemäß einem weiteren Ausführungsbeispiel der Erfindung realisiert, indem der erste Lenker des Kniehebels an seinem freien Ende drehgelenkig mit dem Koppelelement verbunden ist und der Totpunktmechanismus einen Hebel aufweist, der an einem Ende drehgelenkig mit dem Knie des Kniehebels verbunden und am anderen Ende drehgelenkig mit einem bogenförmigen Kupplungselement verbunden ist, wobei das bogenförmige Kupplungselement drehbar, vorzugsweise koaxial mit dem Koppelelement, gelagert ist.The necessary between the drive pinion and the coupling element freewheel for moving the ejection element on the first open position addition is realized according to a further embodiment of the invention by the first link of the toggle lever is pivotally connected at its free end to the coupling element and the dead center mechanism has a lever, which is pivotally connected at one end to the knee of the toggle lever and pivotally connected at the other end with an arcuate coupling element, wherein the arcuate coupling element rotatably, preferably coaxially with the coupling element, is mounted.
Zum Laden des Kraftspeichers ist es notwendig, den Freilauf zwischen dem Kupplungselement und dem Ritzel aufzuheben, um eine Übertragung der auf den Ausstoßelement wirkenden Kraft auf das Koppelelement zu ermöglichen. Gemäß einem Ausführungsbeispiel der Erfindung wird dies erreicht, indem das Antriebsritzel drehfest mit einem koaxial angeordneten, vorzugsweise scheibenförmigen Bremselement verbunden ist, wobei das Bremselement umfangsseitig zum Eingriff mit dem bogenförmigen Kupplungselementes ausgebildet ist. Das heißt, unmittelbar nach bzw. bei Beginn des Schließvorganges des bewegbaren Möbelteiles wird das Bremselement umfangseitig mit dem bogenförmigen Kupplungselement in Eingriff gebracht, sodass die Drehbewegung des Ritzels blockiert wird und die auf den Ausstoßelement wirkende Kraft des sich schließenden bewegbaren Möbelteiles auf das Koppelelement, mittels dem der Kraftspeicher geladen wird, übertragen wird.To load the energy accumulator, it is necessary to cancel the freewheel between the coupling element and the pinion to allow transmission of the force acting on the ejection element to the coupling element. According to one embodiment of the invention, this is achieved by the drive pinion rotatably connected to a coaxially arranged, preferably disc-shaped brake element, wherein the brake element is circumferentially formed for engagement with the arcuate coupling element. That is, immediately after or at the beginning of the closing operation of the movable furniture part, the brake element is circumferentially engaged with the arcuate coupling element, so that the rotational movement of the pinion is blocked and the force acting on the ejection element of the closing movable furniture part on the coupling element, means the energy store is loaded, is transmitted.
Eine einfache Montage der Ausstoßvorrichtung ergibt sich gemäß einem bevorzugten Ausführungsbeispiel dann, wenn die Ausstoßvorrichtung in einem Gehäuse mit einer Austrittsöffnung zumindest für das Ausstoßelement angeordnet ist. Das Gehäuse kann dann in einfacher Weise an einer geeigneten Stelle entweder am bewegbaren Möbelteil oder am Möbelkorpus montiert werden.A simple assembly of the ejection device results according to a preferred embodiment when the ejection device is arranged in a housing with an outlet opening at least for the ejection element. The housing can then be mounted in a simple manner at a suitable location either on the movable furniture part or on the furniture body.
Um sicherzustellen, dass das bewegbare Möbelteil nach Beendigung des Ausstoßvorganges im Wesentlichen immer dieselbe erste Offenstellung erreicht, ist es notwendig den Öffnungswinkel des Ausstoßelementes in der ersten Offenstellung zu definieren, was gemäß einem bevorzugten Ausführungsbeispiel dadurch erreicht wird, dass im Gehäuse wenigstens ein Anschlagelement für das Lagerelement des Antriebsritzels angeordnet ist, wobei das Lagerelement in der ersten Offenstellung des bewegbaren Möbelteils am Anschlagelement anliegt.To ensure that the movable furniture part after completion of the ejection process substantially always the same first open position reached, it is necessary to define the opening angle of the ejection element in the first open position, which is achieved according to a preferred embodiment in that in the housing at least one stop element for the Bearing element of the drive pinion is arranged, wherein the bearing element rests in the first open position of the movable furniture part on the stop element.
Ein weiteres Ausführungsbeispiel der Erfindung sieht vor, dass die Mittel zum Bewegen des Ausstoßelementes über die erste Offenstellung hinaus von einer vorzugsweise bügelförmigen Biegefeder gebildet sind, deren erster Schenkel am Ausstoßelement und deren zweiter Schenkel am Koppelelement angreift. In diesem Fall muss das bewegbare Möbelteil gegen die Kraft der vorzugsweise bügelförmigen Biegefeder in seiner geschlossenen Endlage gehalten werden, was beispielsweise über eine Einzugsvorrichtung oder ein Scharnier erfolgen kann.A further exemplary embodiment of the invention provides that the means for moving the ejection element beyond the first open position are formed by a preferably bow-shaped bending spring whose first leg engages the ejection element and whose second leg engages the coupling element. In this case, the movable furniture part must be held against the force of the preferably bow-shaped spiral spring in its closed end position, which can be done for example via a collection device or a hinge.
Gemäß einem anderen Ausführungsbeisplel ist vorgesehen, dass die Mittel zum Bewegen des Ausstoßelementes über die erste Offenstellung hinaus von einer Biegefeder gebildet sind, deren erster Schenkel am Ausstoßelement und deren zweiter Schenkel, vorzugsweise drehbar und ortsfest, am Gehäuse angreift. Bei entsprechender Anordnung der Biegefeder kann dadurch eine Art Schnappmechanismus realisiert werden, sodass die Biege- oder Drehfeder das Ausstoßelement in Ausgangsstellung arretiert, beim Entriegeln des Kraftspeichers aber überschnappt und das Ausstoßelement in Öffnungsrichtung des bewegbaren Möbelteils beaufschlagt.According to another Ausführungsbeisplel is provided that the means for moving the ejection element beyond the first open position are also formed by a spiral spring whose first leg on the ejection element and the second leg, preferably rotatable and stationary, engages the housing. With an appropriate arrangement of the spiral spring, a kind of snap mechanism can be realized, so that the bending or torsion spring locks the ejection element in the starting position, but snaps when unlocking the force accumulator and acts on the ejection element in the opening direction of the movable furniture part.
Gemäß einem weiteren Ausführungsbeispiel der Erfindung weist die Ausstoßvorrichtung zum Entriegeln der Antriebsvorrichtung weiters einen Auslösmechanismus mit einem Auslöseelement auf. Ein bevorzugtes Ausführungsbeispiel sieht dabei vor, dass der Auslösemechanismus zum spielfreien Anlegen des Auslöseelementes an das bewegbare Möbelteil oder den Möbelkorpus in Schließstellung des bewegbaren Möbelteiles ausgebildet ist, wodurch eine exakte Festlegung des Auslöseweges möglich ist.According to a further embodiment of the invention, the ejection device for unlocking the drive device further comprises a trigger mechanism with a triggering element. A preferred embodiment provides in this case that the trigger mechanism is designed for play-free application of the trigger element to the movable furniture part or the furniture body in the closed position of the movable furniture part, whereby an exact determination of the triggering path is possible.
Weiters soll ein Verfahren zum Öffnen bzw. Schließen eines in oder an einem Möbelkorpus eines Möbels bewegbar gelagerten Möbelteiles mittels einer Ausstoßvorrichtung, die ein von einer verriegelbaren Antriebsvorrichtung beaufschlagtes bzw. beaufschlagbares Ausstoßelement aufweist angegeben werden, welches sich gemäß der Erfindung dadurch auszeichnet, dass ein manuell zu ladender Kraftspeicher der Antriebsvorrichtung während der Schließbewegung des bewegbaren Möbelteiles mittels des Ausstoßelementes aufgeladen wird, wobei der Ladevorgang des Kraftspeichers nach dem Öffnen des bewegbaren Möbelteiles über eine erste Offenstellung hinaus während einer Schließbewegung des bewegbaren Möbelteiles in einem zwischen der ersten Offenstellung und der geöffneten Endlage liegenden Teilabschnitt des Öffnungs- bzw. Schließweges des bewegbaren Möbelteiles gestartet wird.Furthermore, a method for opening or closing a furniture part movably mounted in or on a furniture body of a piece of furniture is to be indicated by means of an ejection device having an ejection element acted upon or acted upon by a lockable drive device, which is characterized according to the invention in that one manually to be charged power storage of the drive device during the closing movement of the movable furniture part is charged by the ejection element, wherein the charging of the energy storage after opening the movable furniture part beyond a first open position during a closing movement of the movable furniture part lying in a between the first open position and the open end position Part of the opening or closing path of the movable furniture part is started.
Im Gegensatz zum Stand der Technik wird also der Ladevorgang des Kraftspeichers bereits zu Beginn der Schließbewegung des bewegbaren Möbelteiles gestartet, wobei gemäß einem bevorzugten Ausführungsbeispiel der Erfindung der Ladevorgang des Kraftspeichers im Wesentlichen bei jeder Schließbewegung des bewegbaren Möbelteiles, vorzugsweise unabhängig von der jeweiligen Offenstellung des bewegbaren Möbelteiles, gestartet wird. Anders ausgedrückt, erfolgt das Laden des Kraftspeichers nach dem Ratschenprinzip, d.h. das Ausstoßelement ist nach Beendigung des Ausstoßvorganges in Bezug auf den Kraftspeicher während des weiteren Öffnungsweges frei beweglich, während es in der entgegen gesetzten Richtung den Kraftspeicher permanent, d.h. in jeder Position beaufschlagt.In contrast to the prior art, therefore, the charging of the energy storage is already started at the beginning of the closing movement of the movable furniture part, wherein according to a preferred embodiment of the invention, the charging of the energy storage substantially at each closing movement of the movable furniture part, preferably independent of the respective open position of the movable Furniture part, is started. In other words, the loading of the force accumulator takes place according to the ratchet principle, ie the ejection element is after completion of the ejection process in relation to the energy storage freely movable during the further opening travel, while in the opposite direction it acts on the energy accumulator permanently, ie in any position.

Eine Grundidee der Erfindung besteht also darin, das Ausstoßelement 5 nach Beendigung des Ausstoßvorganges in eine - in Öffnungsrichtung gesehen - hinter der Lage O' liegende Stellung E', die der Lage des Ausstoßelementes 5 nach Beendigung des Öffnungsvorganges des bewegbaren Möbelteils 3 entspricht, zu bringen. Dadurch wird erreicht, dass das bewegbare Möbelteil bereits zu Beginn bzw. unmittelbar nach Beginn des Schließvorganges mit dem Ausstoßelement 5 koppelbar ist, wodurch bei entsprechender Koppelung des Ausstoßelementes 5 mit der Antriebsvorrichtung der Ladevorgang des Kraftspeichers bereits im ersten Abschnitt des Schließweges starten kann, während bei den bekannten Vorrichtungen das Laden des Kraftspeichers in dem der Schließstellung unmittelbar vorgelagerten Teilabschnitt des Schließweges des bewegbaren Möbelteils erfolgt.A basic idea of the invention is therefore that the
Aufgrund der Erfindung und der dem Ratschenprinzip folgenden Ausbildung der Ausstoßvorrichtung, derart, dass das Ausstoßelement nach Beendigung des Ausstoßvorganges in Bezug auf den Kraftspeicher der Antriebsvorrichtung während des weiteren Öffnungsweges frei beweglich ist, während es in der entgegen gesetzten Richtung den Kraftspeicher permanent, d.h. in jeder Position beaufschlagt, kann nun im Wesentlichen der gesamte Weg, den das bewegbare Möbelteil beim Schließen zurücklegt, zum Laden des Kraftspeichers benutzt werden. Dabei kann einerseits der Weg, den das bewegbare Möbelteil während des Ladevorganges des Kraftspeichers zurücklegt, größer gewählt werden als der Weg, den das bewegbare Möbelteil während des Ausstoßvorganges zurücklegt, sodass ein Benutzer aufgrund des verlängerten Weges eine geringere Kraft aufbringen muss, um den Kraftspeicher zu laden.Due to the invention and the ratchet following training of the ejection device, such that the ejection element is free to move after completion of the ejection process with respect to the energy storage of the drive device during the further opening path, while in the opposite direction the energy storage permanently, i. acted upon in any position, can now be used to load the energy storage device essentially the entire path that covers the movable furniture part when closing. In this case, on the one hand, the path traveled by the movable furniture part during the charging process of the energy storage, be chosen to be greater than the path that covers the movable furniture part during the ejection process, so that a user due to the extended path must apply less force to the energy storage load.
Die zweite Möglichkeit besteht darin, die Wegstrecke, die das bewegbare Möbelteil während des Ladevorganges und des Ausstoßvorganges zurücklegt, im Wesentlichen gleich lang zu belassen, diesen Abschnitt aber in die unmittelbare Nähe der geöffneten Endlage des Schließ- bzw. Öffnungsweges des bewegbaren Möbelteils zu verlegen. Dadurch wird erreicht, dass der Benutzer die Kraft zum Laden des Kraftspeichers gleich zu Beginn des Schließvorganges aufbringt, wodurch dem Benutzer der Eindruck eines gleichmäßigen Schließvorganges des bewegbaren Möbelteils vermittelt wird.The second possibility is to leave the path that travels the movable furniture part during the charging process and the ejection process, substantially the same length, but to move this section in the immediate vicinity of the open end position of the closing or opening path of the movable furniture part. This ensures that the user applies the force for loading the energy storage right at the beginning of the closing process, whereby the user the impression of a uniform closing operation of the movable furniture part is conveyed.

Zwischen dem Unterteil 27' und dem Oberteil 27 des Ausstoßelementes 5 sind ebenfalls drehbar und koaxial mit dem Ausstoßelement 5 ein Lagerelement 13, ein Kupplungselement 16 und eine Koppelelement 14 angeordnet. Im Lagerelement 13 sind ein Ritzel 12 und ein Bremsscheibe 19, die drehfest miteinander verbunden sind, in einer zur Drehachse des Ausstoßelementes 5 bzw. des Lagerelementes 13 im Wesentlichen parallelen Achse drehbar gelagert. Das Ritzel 12 ist zum Eingriff mit einem am Oberteit 27 des Ausstoßelementes 5 zahnradförmigen Abschnitt Z (
Beim gezeigten Ausführungsbeispiel werden die Mittel zum Bewegen des Ausstoßelementes 5 über eine erste Offenstellung von zwei Hilfsantrieben 23,23' gebildet, wobei der erste Hilfsantrieb 23' in Form einer Biegefeder das Lagerelement 13, dessen Bewegbarkeit durch ein im Gehäuse angeordnetes Anschlagelement 22 begrenzt ist, in Öffnungsrichtung beaufschlagt, um auf diese Weise den zum Bewegen des Ausstoßelementes 5 notwendigen Freilauf zwischen der Bremsscheibe 19 und dem Kupplungselement 16 sicherzustellen. Der zweite Hilfsantrieb 23' wird von einer Drehfeder gebildet, deren erster Schenkel 24 am Oberteil 27 des Ausstoßelementes 5 angreift, während der zweite Schenkel 24' drehbar aber ortsfest mit dem Gehäuse 20 der Ausstoßvorrichtung 4 verbunden ist.In the embodiment shown, the means for moving the
Weiters ist in der Ausstoßvorrichtung 4 die Antriebsvorrichtung 6 für das Ausstoßelement 5 angeordnet, die einen manuell zu ladenden Kraftspeicher 8 in Form einer Zugfeder, einen Haltebügel 7 für den Kraftspeicher 8 und ein Einstellelement 9 zum Justieren des Kraftspeichers 8 aufweist. Das Einstellelement 9 ist im Gehäuse 20 derart angeordnet, dass es von außen zugänglich ist, wodurch eine einfache und unkomplizierte Justierung des Kraftspeichers 8 sichergestellt wird. An seinem freien Ende ist der als Zugfeder ausgebildete Kraftspeicher 8 der Antriebsvorrichtung 6 an einer Ausnehmung 10 des Koppelelementes 14 eingehängt, wodurch beim Entladen des Kraftspeichers 8 das Koppelelement 14 in Richtung der Antriebsvorrichtung 6 bewegt wird.Furthermore, in the
Die Verriegelung der Antriebsvorrichtung 6 erfolgt beim dargestellten Ausführungsbeispiel über einen Kniehebel 17 und einen Totpunktmechanismus. Dabei ist der erste Lenker 18 des Kniehebels 17 an seinem freien Ende drehgelenkig mit dem Koppelelement 14 verbunden, während der zweite Lenker 18' drehgelenkig aber ortsfest am Gehäuse 20 der Ausstoßvorrichtung 4 angeordnet ist. Der Totpunktmechanismus weist einen Hebel 15 auf, der an einem Ende drehgelenkig mit dem Knie des Kniehebels 17 und am anderen Ende drehgelenkig mit dem Kupplungselement 16 verbunden ist. Die Verriegelung der Antriebsvorrichtung 6 erfolgt also dadurch, dass beim Laden des Kraftspeichers 8 über das Ausstoßelement 5 das Kupplungselement 16 aufgrund seines Eingriffs mit der Bremsscheibe 19, und mit dem Kupplungselement 16 das Koppelelement 14, so weit nach rechts bewegt wird, bis der Kraftspeicher 8 vollständig geladen ist und der Hebel 15 den Totpunkt des Kniehebels 17 überschreitet, wodurch der Kniehebel 17 - und damit das Kopplungslement 14 - arretiert wird.The locking of the
Das Entriegeln der Antriebsvorrichtung 6 erfolgt über einen Auslösemechanismus 25, der ein Auslöseelement 26, ein exzenterförmiges Drehelement 33, eine Rückstellfeder 32 für das Drehelement 33, ein keilförmiges Stellelement 34, einen Auslösehebel 35, ein Dämpferelement 36 und ein vom Dämpferelement 36 beaufschlagtes Rückholelement 37 für das Drehelement 33 aufweist. Die Koppelung des Auslösemechanismus 25 mit dem Hebel 15 des Totpunktmechanismus erfolgt über einen, vorzugsweise hebelförmigen, Verbindungsteil 38, der an seinem einen Ende drehgelenkig mit dem Auslösehebel 35 und an seinem gegenüberliegenden Ende drehgelenkig mit dem Hebel 15 des Totpunktmechanismus bzw. dem Kupplungselement 16 verbunden ist.The unlocking of the

Aus Übersichtsgründen wurde auf die Abbildung des Deckels des Gehäuses 20 und des oberen Teiles 27 des Ausstoßelementes 5 verzichtet. In der gezeigten Stellung ist der Kraftspeicher 8 der Antriebsvorrichtung 6 geladen. Das heißt, die Zugfeder, die den Kraftspeicher 8 bildet, ist in der Federhaltung 7 gelagert und mittels des Koppelelementes 14 gespannt. Das Gehäuse 20 weist auf seiner dem bewegbaren Möbelteil 3 zugewandten Stirnseite eine Austrittsöffnung 21 für das Ausstoßelement 5 und das Auslöseelement 26 auf. Alle übrigen Teile der Ausstoßvorrichtung 4 sind innerhalb des geschlossenen Gehäuses 20 angeordnet, mit Ausnahme des Einstellelementes 9 für den Kraftspeicher 8.For reasons of clarity, the figure of the cover of the
Die Verriegelung des Kraftspeichers 8 erfolgt über einen auf das Koppelelement 14 wirkenden Kniehebel 17, der über einen Hebel 15 eines Totpunktmechanismus in der gezeigten Stellung arretiert ist. Das Ausstoßelement 5 wird über den als Drehfeder ausgebildeten Hilfsantrieb 23 in seiner Ausgangsstellung S' arretiert. Dabei ist der Hilfsantrieb 23 derart angeordnet, dass der eine Schenkel 24' der Feder in einem Lagerpunkt 40 am Gehäuse und der zweite Schenkel 24 des Hilfsantriebes 23 in einem Lagerpunkt 39 am Unterteil 27' des Ausstoßelementes 5 gelenkig angeordnet sind.The locking of the

In der gezeigten Stellung sind also das Koppelelement 14, das Kupplungselement 16 und das Ausstoßelement 5 aufgrund des verriegelten Kniehebels 17 bzw. der Lage des Hilfsantriebes 23 nicht frei beweglich, während das Lagerelement 13 und damit das Ritzel 12 und das Bremselement 19 drehbeweglich sind. Dabei wird das Lagerelement 13 von einem als Bügelfeder ausgebildeten Hilfsantrieb 23' beaufschlagt und von diesem in Öffnungsrichtung des bewegbaren Möbelteiles beaufschlagt, wobei die Zähne des Ritzels 12 in den zahnradförmig ausgebildeten Abschnitt Z des Oberteils 27 des Ausstoßelementes 5 eingreifen.In the position shown, therefore, the
Dadurch, dass das Lagerelement 13 über den Hilfsantrieb 23' vom Kupplungselement 16 weggedrückt wird, kann der während des Öffnungsvorganges zwischen dem Kupplungselement 16 und der Bremsscheibe 19 notwendige Freilauf sichergestellt werden. Würde nämlich das Bremselement 19 während des Öffnungsvorganges am zahnradförmig ausgebildeten Abschnitt Z' des Kupplungselementes 16 eingreifen, hätte dies eine Blockierung des Ritzels 12 und damit des Ausstoßelements 5 zur Folge, d.h., das Aufstoßen des bewegbaren Möbelteils 3 mittels des Ausstoßelementes 5 wäre bei einer derartigen Konstellation gar nicht möglich.Characterized in that the bearing
Wenn auch der dargestellte Auslösemechanismus ein bevorzugtes Ausführungsbeispiel darstellt, soll die Erfindung nicht auf dieses gezeigte Ausführungsbeispiel beschränkt sein. So wäre es durchaus möglich und denkbar, das Auslösen der Ausstoßvorrichtung anstatt mittels des bewegbaren Möbelteiles 3 bspw. durch einen Schalter, einen Taster oder durch direkten Druck auf das Auslöselement 26 zu realisieren.Although the illustrated triggering mechanism is a preferred embodiment, the invention should not be limited to this embodiment shown.

Selbstverständlich wäre es auch möglich, die Wirkkraft des Hilfsantriebes 23 so groß zu wählen, dass mittels des Hilfsantriebes 23 nicht nur der Ausstoßelement 5 sondern auch das bewegbare Möbelteil 3 über die erste Offenstellung O hinaus in eine geöffnete Endlage E bewegt werden könnte. Eine derartige Ausgestaltung würde dazu führen, dass der Benutzer beim Schließen des bewegbaren Möbelteiles 3 zusätzlich zur Kraft, die notwendig ist, um den Kraftspeicher 8 aufzuladen, noch die dann relativ große Kraft zum Laden des Hilfsantriebes aufbringen müsste, wodurch für den Benutzer der Eindruck eines schwergängigen bewegbaren Möbelteiles entstehen würde. Allerdings könnte bei entsprechend großer Wirkkraft des Hilfsantriebes 23 ein Möbel 1 mit einem bewegbaren Möbelteil 3 und einer Ausstoßvorrichtung 4 realisiert werden, bei der der Benutzer zum Bewegen des bewegbaren Möbelteiles 3 aus einer Schließstellung in eine geöffnete Endlage lediglich die Ausstoßvorrichtung 4 auslösen müsste, bspw. durch Druck auf das bewegliche Möbelteil, wodurch das bewegbare Möbelteil 3 dann in einem ersten Abschnitt durch das Ausstoßelement 5 und in einem weiteren Abschnitt mittels des Hilfsantriebes 23 in seine geöffnete Endlage bewegt werden würde, ohne dass ein weiteres Zutun des Benutzers notwendig wäre.Of course, it would also be possible to choose the effective force of the
Beim dargestellten Ausführungsbeispiel hingegen reicht die Wirkkraft des Hilfsantriebes 23 gerade noch aus, um das Ausstoßelement 5 dem bewegbaren Möbelteil 3 nachzuführen, sodass die vom Benutzer beim Schließen des bewegbaren Möbelteils aufzubringende Kraft zum Laden des Hilfsantriebes 23 von diesem gar nicht wahrgenommen wird.In the illustrated embodiment, however, the active force of the

Wie schon beim ersten Ausführungsbeispiel weist der Auslösemechanismus 25 ein Auslöselement 26, ein exzenterförmiges Drehelement 33 und ein Dämpferelement 36 auf, wobei das Dämpferelement 36 ein Lagerteil 42, einen Drehdämpfer 43 und ein Ritzel 44 umfasst. Im Unterschied zum ersten Ausführungsbeispiel ist das Auslöselement 26 beim zweiten Ausführungsbeispiel direkt mit dem exzenterförmigen Drehelement 33 über ein Wälzgelenk verbunden. Die Verbindung des Auslösemechanismus 25 mit dem Kupplungselement 16 erfolgt zwar wieder über einen hebelförmigen Verbindungsteil 38, der jedoch an seinem einen Ende mit dem Lagerteil 42 des Dämpferelementes 36 drehgelenkig verbunden ist. Das heißt, das Lagerteil 42 bzw. der Drehdämpfer 43 aus dem zweiten Ausführungsbeispieles übernehmen die Funktion des Auslösehebels 35 bzw. des Rückholelementes 37 aus dem ersten Ausführungsbeispiel.As in the first embodiment, the triggering
Auf seinem gegenüberliegenden Ende ist der hebelförmige Verbindungsteil 38 nicht mehr drehgelenkig mit dem Kupplungselement 16 verbunden. Stattdessen ist am freien Ende des hebelförmigen Verbindungsteiles 38 eine Rastnase 45 angeordnet, die zum Eingriff mit einem am Kupplungselement 16 ausgebildeten Vorsprung 46 ausgebildet ist.

Im Gegensatz zum ersten Ausführungsbeispiel weist das zweite Ausführungsbeispiel nur einen Hilfsantrieb 23 auf, der von einer bügelförmigen Feder gebildet ist, die zwischen dem Koppelement 14 und dem Ausstoßelement 5 wirkt. Ein weiterer Unterschied besteht in der Ausbildung der Umfangsfläche des scheibenförmigen Bremselementes 19 sowie des entsprechenden Abschnittes Z' am Kupplungselement 16. Während beim ersten Ausführungsbeispiel der Eingriff zwischen dem Bremselement 19 und dem Kupplungselement 16 aufgrund der zahnradförmigen Ausbildung hauptsächlich formschlüssig erfolgte, greifen beim zweiten Ausführungsbeispiel das Bremselement 19 und das Kupplungselement 16 reibschlüssig aneinander.In contrast to the first embodiment, the second embodiment has only one
