Description

Schwenkbeschlag  swivel fitting
Die Erfindung betrifft einen Schwenkbeschlag zum Verschwenken einer an einem Möbelkorpus angelenkten Klappe. The invention relates to a pivot fitting for pivoting a hinged to a furniture body flap.
Solche Schwenkbeschläge finden Verwendung, um einerseits die um eine horizontale Achse verschwenkte Klappe in Offenstellung selbsttätig zu halten und sie andererseits in einer Schließstellung zu fixieren, wozu sie durch die Kraft des Kraftspeichers, üblicherweise einer Zugfeder, gegen die zugeordneten Kanten des Möbelkorpus gezogen wird. Such swivel fittings are used, on the one hand to automatically hold the flap pivoted about a horizontal axis in the open position and on the other hand to fix it in a closed position, to which it is pulled by the force of the energy storage, usually a tension spring, against the associated edges of the furniture body.
Ein derartiger Schwenkbeschlag ist in der DE 296 05 551 U1 thematisiert. Da- bei greift ein als Zugfeder ausgebildeter Kraftspeicher an einer Hebelanordnung an, die einerseits an einer Korpuswand und andererseits an der Klappe befestigt ist, wobei die Zugfeder die Klappe sowohl in einer aufgeschwenkten Stellung hält, wie auch in einer Schließstellung an den Möbelkorpus zieht. Problematisch ist hierbei jedoch, dass während des Verschwenkens der Klappe diese manuell geführt werden muss, um sie gegen die Kraft der Zugfeder zu halten, durch die die Klappe ansonsten immer in eine Schließstellung gezogen wird, mit Ausnahme der Offenstellung, in der, wie erwähnt, die Klappe durch die Zugfeder gehalten wird. Such a pivot fitting is thematized in DE 296 05 551 U1. In this case, a force accumulator designed as a tension spring acts on a lever arrangement which is fastened on the one hand to a body wall and on the other hand to the flap, wherein the tension spring holds the flap both in a swung-open position and in a closed position pulls against the furniture carcass. The problem here is, however, that during the pivoting of the flap, this must be done manually to keep them against the force of the tension spring through which the flap is otherwise always pulled into a closed position, with the exception of the open position in which, as mentioned, the flap is held by the tension spring.
Die Handhabung beim Verschwenken der Klappe gestaltet sich auch insofern problematisch, als diese quasi ungebremst in ihre Schließstellung gezogen wird, so dass sie mit weitgehend unverminderter Zugkraft gegen den Möbelkorpus gepresst wird. The handling when pivoting the flap is also problematic insofar as it is almost unchecked pulled into its closed position, so that it is pressed with largely undiminished tensile force against the furniture body.
Um hier Abhilfe zu schaffen, ist in der DE 20 2005 016 375 der Einsatz einer Dämpfungseinrichtung vorgeschlagen, mit der der Schließvorgang bzw. das Anschlagen der Klappe am Möbelkorpus gedämpft wird. Unabhängig davon, dass damit das Halteproblem während des Verschwenkens nicht gelöst wird, sind die bekannten Schwenkbeschläge nur mit einer Vielzahl an Bauteilen zu realisieren, insbesondere hinsichtlich einer notwendigen Hebelkinematik, was nicht nur zu erheblichen Fertigungskosten führt, sondern auch die Montage des jeweiligen Schwenkbeschlages erschwert. Als nachteilig, insbesondere auch bezüglich einer ausreichenden Standzeit ist auch eine andere Konstruktion anzusehen, mit der sozusagen eine Zwangsführung der Klappe erreicht werden soll und bei der ein Nocken in Korrespondenz mit einer Steuerkurve zum Einsatz kommt, wobei der Nocken federbelastet ist. To remedy this situation, the use of a damping device is proposed in DE 20 2005 016 375, with the closing process or the impact of the flap is damped on the furniture body. Regardless of the fact that thus the holding problem is not solved during pivoting, the known pivot fittings are to be realized only with a variety of components, in particular with regard to a necessary lever kinematics, which not only leads to significant production costs, but also complicates the installation of the respective pivot fitting. A disadvantage, especially with respect to a sufficient service life is also to consider another design, so to speak a forced operation of the flap is to be achieved and in which a cam is used in correspondence with a control cam, wherein the cam is spring loaded.
Durch die notwendigerweise hohen Federkräfte unterliegen die beteiligten Bauteile im Bewegungsablauf einer relativ großen Reibung sowie einer hohen Flächenpressung, die zu einer Beschädigung der Steuerkontur des Nockens oder einer darauf geführten Rolle führen kann. Naturgemäß ist dies inakzeptabel, zumal der Schwenkbeschlag in seiner Funktion dann beeinträchtigt ist und schlimmstenfalls ersetzt werden muss. Due to the necessarily high spring forces, the components involved in the movement of a relatively large friction and a high surface pressure, which can lead to damage to the control contour of the cam or a guided role on it. Of course, this is unacceptable, especially since the pivot fitting is impaired in its function and in the worst case must be replaced.
Der Erfindung liegt die Aufgabe zugrunde, einen Schwenkbeschlag der gat- tungsgemäßen Art so weiterzuentwickeln, dass seine Funktionsfähigkeit, d.h. der Bedienkomfort beim Verschwenken der Klappe verbessert, die Standzeit erhöht und die Anzahl der notwendigen Bauteile reduziert wird, um die Herstellungskosten zu senken. Außerdem wird die Systemreibung wesentlich reduziert, so dass geringe Federkräfte bei einer gleich ausgeführten Klappe not- wendig sind. The object of the invention is to further develop a swivel fitting of the generic type such that its functionality, ie. the ease of use when pivoting the flap improves, increases the service life and the number of components required is reduced to reduce manufacturing costs. In addition, the system friction is significantly reduced, so that low spring forces are necessary with a flap executed the same.
Diese Aufgabe wird durch einen Schwenkbeschlag mit den Merkmalen des Anspruchs 1 gelöst. Der neue Schwenkbeschlag zeichnet sich zunächst einmal dadurch aus, dass er funktional mit relativ wenig Bauteilen, d.h. deutlich weniger als bei einem Schwenkbeschlag nach dem Stand der Technik, auskommt. Daraus ergeben sich geringe Herstellungskosten, sowohl resultierend aus einem sparsamen Materialeinsatz wie auch aus kürzeren Fertigungszeiten, was insoweit bedeut- sam ist, als solche Schwenkbeschläge als Serienartikel in großen Stückzahlen Verwendung finden. This object is achieved by a pivot fitting with the features of claim 1. The new pivot fitting is initially characterized by the fact that it is functional with relatively few components, i. significantly less than in a pivot fitting according to the prior art, gets by. This results in low manufacturing costs, both as a result of economical use of materials and shorter production times, which is significant insofar as such swivel fittings are used as mass-produced mass-produced items.
Die Hebelanordnung wird durch eine an sich bekannte Viergelenk-Kette gebildet, deren Bewegungsablauf durch das Steuerelement in Korrespondenz mit dem Kraftspeicher unterstützt wird. Grundsätzlich können mit dem System aber auch alle anderen Hebelanordnungen unterstützt werden. The lever assembly is formed by a known four-link chain whose movement is supported by the control in correspondence with the energy storage. In principle, however, all other lever arrangements can also be supported with the system.
Dabei wird durch das Steuerelement die Kraft des Kraftspeichers, bevorzugt einer Zugfeder oder eines Zugfederblocks derart auf die Hebelanordnung, d.h. den Gelenkhebel, geleitet, dass die Klappe in einem vorgegebenen Bereich der Schwenkstellung selbsttätig verharrt, also im Gleichgewicht bleibt. In einem Schwenkbereich vor der vollständig geschlossenen Position bzw. in einem Schwenkbereich der vollständig geöffneten Position kann die Klappe selbst- ständig schließen oder öffnen. In this case, by the control, the force of the force accumulator, preferably a tension spring or a tension spring block on the lever arrangement, ie the articulated lever, passed that the flap automatically remains in a predetermined range of the pivot position, so remains in balance. In a swivel range in front of the fully closed position or in a swivel range of the completely open position, the flap can close or open automatically.
Nach einem weiteren Gedanken der Erfindung weist das Steuerelement eine verdrehbare Kurvenscheibe auf, mit einer Steuerkontur, an der ein an der Kurvenscheibe befestigtes, flexibles Zugmittel anliegt, das eine Verlängerung des Kraftspeichers bildet. According to a further aspect of the invention, the control element has a rotatable cam, with a control contour against which a flexible traction means fastened to the cam engages, which forms an extension of the force accumulator.
Dabei kann die Anbindung des Zugmittels, das im Übrigen aus einem Band, einer Kette, einem Zahnriemen, einem Seil oder dergleichen bestehen kann, so an der Kurvenscheibe erfolgen, dass die Kraftrichtung des Kraftspeichers in Schließstellung der Klappe, bezogen auf die Schwenkrichtung, oberhalb der Achse eines das Steuerelement tragenden Schwenkzapfens und in Offenstellung unterhalb positioniert ist, wodurch sich eine Unterstützung der jeweils unterschiedlichen Drehrichtungen des Steuerelementes ergibt. Durch diese Anordnung wird erreicht, dass beim Verschwenken der Klappe, unmittelbar vor Erreichen der jeweiligen Endstellung, die Schwenkbewegung unterstützt wird. In this case, the connection of the traction means, which may otherwise consist of a band, a chain, a toothed belt, a rope or the like, done on the cam so that the direction of force of the energy storage in the closed position of the flap, based on the pivoting direction, above the Axis of the control bearing pivot pin and is positioned in the open position below, resulting in a support of each different directions of rotation of the control. By this arrangement it is achieved that during pivoting of the flap, immediately before reaching the respective end position, the pivoting movement is supported.
Nach einem weiteren Gedanken der Erfindung weist das Steuerelement neben der Kurvenscheibe wenigstens ein weiteres Getriebeteil auf, das hier als zur Kurvenscheibe verdrehsicher gehaltenes Ritzel ausgeführt ist. Dieses Ritzel wirkt mit weiteren Getriebeelementen zusammen, vorzugsweise mit einem Zahnradsegment, das fest mit dem Gelenkhebel verbunden ist. Dabei sind das Ritzel und die Kurvenscheibe um eine gemeinsame Drehachse verschwenkbar, die durch einen einseitig gehaltenen Schwenkzapfen gebildet wird. Bevorzugt sind zwei sich gegenüberliegende Schwenkzapfen vorgesehen, deren Drehachsen fluchten und die stirnseitig abständig zueinander angeordnet sind, wobei auf einem Schwenkzapfen das Ritzel und auf dem anderen die Kurvenscheibe gelagert sind. According to a further aspect of the invention, the control element in addition to the cam on at least one further gear part, which is designed here as a cam to prevent rotation held pinion. This pinion cooperates with other transmission elements, preferably with a gear segment which is fixedly connected to the articulated lever. The pinion and the cam are pivotable about a common axis of rotation, which is formed by a pivot pin held on one side. Preferably, two opposing pivot pins are provided, whose axes of rotation are aligned and the front side are spaced apart, wherein on a pivot pin, the pinion and on the other, the cam are mounted.
Wie erwähnt, wird durch den neuen Schwenkbeschlag erreicht, dass die Klappe in jeder Schwenkstellung unterstützungsfrei verharrt. Dazu variiert der Krümmungsradius einer Steuerkurve der Kurvenscheibe im Kurvenverlauf, der an die sich, je nach Schwenkposition der Klappe, verändernden, auf die Kur- venscheibe bzw. den Kraftspeicher wirkenden Drehmomente angepasst ist. Dabei wird das in jeder Schwenkstellung der Klappe unterschiedliche Drehmoment im Wesentlichen durch das Gewicht der Klappe und dem sich verändernden Hebelarm, der sich aus dem sich verändernden Abstand der Steuerkontur zur Drehachse des Steuerelements ergibt, bestimmt. As mentioned, is achieved by the new pivot fitting that the flap remains support-free in each pivot position. For this purpose, the radius of curvature of a control cam of the cam varies in the course of the curve, which changes to the, depending on the pivot position of the flap, changing the Kur- Venscheibe or the energy storage torque acting adapted. In this case, the different torque in each pivot position of the flap is essentially determined by the weight of the flap and the changing lever arm, which results from the changing distance of the control contour to the axis of rotation of the control.
Weitere vorteilhafte Ausbildungen der Erfindung sind in den Unteransprüchen gekennzeichnet. Ein Ausführungsbeispiel der Erfindung wird nachfolgend anhand der beigefügten Zeichnungen beschrieben. Further advantageous embodiments of the invention are characterized in the subclaims. An embodiment of the invention will be described below with reference to the accompanying drawings.

This energy storage device 2 consists in the example of a spring block with three mutually parallel tension springs 14 and is connected via a centrally connected traction means 4 with a control element 6, wherein the traction means 4 forms the extension of an effective axis 1 6 of the energy accumulator 2. Instead of the tension springs 14 also other suitable energy storage can be used, for example a compression spring with deflection, torsion springs, roller springs or the like. The control element 6 is fixed relative to the housing but rotatable and motion-dependent with a toggle lever 1 2 of a lever assembly 1 1, wherein the lever assembly 1 1 is designed as a four-bar chain and the toggle lever 1 2 on the one hand on the flap 1 5 and on the other hand pivotable in the housing is held.
Das Steuerelement 6 weist eine Kurvenscheibe 7 sowie ein Ritzel 8 auf, die verdrehfest zueinander auf dem Schwenkzapfen 9 gelagert sind. The control element 6 has a cam 7 and a pinion 8, which are mounted rotationally relative to one another on the pivot pin 9.
Das Zugmittel 4 liegt an einer Steuerkontur 10 der Kurvenscheibe 7 an und ist daran mittels eines Anschlusselementes 5 befestigt. The traction means 4 bears against a control contour 10 of the cam 7 and is fastened thereto by means of a connection element 5.
Das Ritzel 8 wiederum greift in die Zähne eines Zahnradsegmentes 1 3 ein, das verdrehfest mit dem Gelenkhebel 1 2 und zwar im Bereich dessen Schwenkachse im Gehäuse verbunden ist. The pinion 8 in turn engages in the teeth of a gear segment 1 3, which is rotationally connected to the toggle lever 1 2 and that is connected in the region of the pivot axis in the housing.
In der Figur 1 ist eine Schließstellung der Klappe 15 abgebildet. Bei deren Verschwenken in Richtung einer in der Figur 2 gezeigten Offenstellung, bei der die Klappe 1 5 parallel verschoben wird, wird der Gelenkhebel 1 2 verdreht, ebenso wie das Steuerelement 6, in dessen Ritzel 8 die Zähne des Zahnradsegmentes 13 eingreifen. In Schließposition ist der Kraftspeicher 2, d.h., sind die Zugfedern 14 gespannt. Dabei liegt das Zugmittel 4, das im Übrigen über ein Anschlusselement 5 an der Kurvenscheibe 7 befestigt ist, in Schwenkrichtung des Gelenkhebels 1 2 gesehen oberhalb der Achse des Schwenkzapfens 9, so dass das Ritzel 8 entgegen dem Uhrzeigersinn belastet ist, womit beim Schließen der Klappe 1 5 das Zahnradsegment 1 3 im Uhrzeigersinn verdreht und gegen den Möbelkorpus gedrückt wird. FIG. 1 shows a closed position of the flap 15. When pivoting in the direction of an open position shown in Figure 2, in which the flap 1 5 is moved parallel, the hinge lever 1 2 is rotated, as well as the control 6, in the pinion 8, the teeth of the gear segment 13 engage. In the closed position, the energy accumulator 2, that is, the tension springs 14 are tensioned. In this case, the traction means 4, which is fastened by the way via a connecting element 5 on the cam 7, seen in the pivoting direction of the articulated lever 1 2 above the axis of the pivot pin 9, so that the pinion 8 is loaded counterclockwise, which when closing the flap 1 5 the gear segment 1 3 is rotated clockwise and pressed against the furniture body.
Beim Aufschwenken der Klappe 15 wird das Steuerelement 6 entgegengesetzt, also im Uhrzeigersinn, verdreht. Durch die Zugkraft des Kraftspeichers 2 und die Geometrie der Kurvenscheibe, d.h. durch den Verlauf der Steuerkontur 1 0, mit Änderung des Abstands zur Achse des Schwenkzapfens 9 verändert sich die Geschwindigkeit des zurückgelegten Wegs des Kraftspeichers bei konstanter Winkelgeschwindigkeit der Hebelanordnung 1 1 . In jeder Stellung der Hebelanordnung 1 1 bzw. der Klappe 15 sorgt deshalb das sich verändernde Drehmoment, resultierend aus der Zugkraft des Kraftspeichers 2 und dem Abstand der Steuerkontur 10 zum Schwenkzapfen 9, für ein unterstützungsfreies Halten der Klappe 15. When swinging the flap 15, the control 6 is opposite, so in a clockwise direction, twisted. Due to the tensile force of the force accumulator 2 and the geometry of the cam, ie by the course of the control contour 1 0, with change of the distance to the axis of the pivot pin 9, the speed of the path covered the force accumulator at constant angular velocity of the lever assembly 1 1 changes. In each position of the lever assembly 1 1 and the flap 15 therefore provides the changing torque, resulting from the tensile force of the energy accumulator 2 and the distance of the control contour 10 to the pivot pin 9, for a support-free holding the flap 15th
Wie besonders deutlich in der Figur 2 zu erkennen ist, liegt das Zugmittel 4 nun gegenüber dem Schwenkzapfen 9 an der in Schwenkrichtung unteren Seite der Kurvenscheibe 7 an, also gegensätzlich zur Position in Schließstellung der Klappe 15. As can be seen particularly clearly in Figure 2, the traction means 4 is now relative to the pivot pin 9 on the lower side in the pivoting direction of the cam 7, ie opposite to the position in the closed position of the flap 15th
Deutlich erkennbar ist, dass in Schließstellung der Klappe 15 (Figur 1 ) der Kraftspeicher 2 gespannt ist, während er in Offenstellung der Klappe 15 (Figur 2) relativ dazu entspannt ist. Gleichzeitig ist die Wirkachse 16 gegenüber der Drehachse des Schwenkzapfens 9 lageverändert. It can be clearly seen that in the closed position of the flap 15 (Figure 1) of the energy storage device 2 is stretched while it is relaxed in the open position of the flap 15 (Figure 2) relative thereto. At the same time the axis of action 16 is changed in position relative to the axis of rotation of the pivot pin 9.
Durch die einseitige Halterung des Schwenkzapfens 9 im Sinne eines Kragzapfens kann das Zugmittel 4 behinderungsfrei in die jeweilige Endlage durch Verdrehen der Kurvenscheibe 7 geführt werden. Due to the one-sided mounting of the pivot pin 9 in the sense of a Kragzapfens the traction means 4 can be performed without hindrance in the respective end position by turning the cam 7.
