Description

Die Erfindung betrifft eine Synchronführung eines in einem Möbelkorpus schienengeführten Schubelementes nach dem Oberbegriff des Anspruchs 1.The invention relates to a synchronous guide of a railcar-guided in a furniture body push element according to the preamble of claim 1.

Um ein gleichmäßiges Verschieben des Schubelementes zu gewährleisten, d.h., um vor allem beim Herausziehen des Schubelements aus dem Möbelkorpus Verwindungen und Verkantungen zu vermeiden, wie sie insbesondere bei breiten und/oder labilen Schubelementen auftreten können, kommen Synchronführungen zum Einsatz, durch die ein gleichmäßiger und paralleler Auszug des Schubelementes erreicht werden soll.In order to ensure a uniform displacement of the pusher element, ie in order to avoid twisting and tilting, especially when pulling out of the pusher element from the furniture body, as they may occur especially in wide and / or unstable pushers, synchronous guides are used by a uniform and parallel extension of the thrust element to be achieved.

Eine solche Synchronführung ist aus der EP 1 810 596 A1 bekannt. Dabei ist das jeweilige Zahnrad Bestandteil eines Schienenpakets, bestehend aus einer an einer Korpuswange befestigten Auszugsschiene, einer darin verschiebbar gelagerten Mittelschiene sowie einer an der Mittelschiene verschieblich festgelegten Laufschiene, die am Schubelement angeschlossen ist.Such a synchronous guide is from the EP 1 810 596 A1 known. In this case, the respective gear is part of a rail package, consisting of a mounted on a carcass leg extract rail, a displaceably mounted therein center rail and a displaceably fixed to the center rail running rail, which is connected to the thrust element.

Das zugeordnete Zahnrad ist mit der Mittelschiene fest verbunden, während ein gattungsgemäßer Treibriemen einerseits am Schubelement und andererseits an der Mittelschiene befestigt ist.The associated gear is fixedly connected to the center rail, while a generic belt is attached on the one hand to the pusher and on the other hand to the center rail.

Die beiden sich gegenüberliegenden, jeder Seitenwand des Schubelementes zugeordneten Zahnräder sind verdrehsicher an den beiden Enden einer drehbaren Koppelstange befestigt, über die die Bewegung des einen Zahnrades synchron auf das andere Zahnrad übertragen wird, wobei die eigentliche Drehbewegung der Zahnräder sich aus der linearen Relativbewegung des Schubelements zur Mittelschiene beim Verschieben des Schubelementes ergibt.The two opposing, each side wall of the thrust element associated gears are secured against rotation at the two ends of a rotatable coupling rod via which the movement of a gear is synchronously transmitted to the other gear, wherein the actual rotational movement of the gears from the linear relative movement of the pusher to the middle rail when moving the thrust element results.

Da das genannte Schienenpaket jeweils nur hinsichtlich seiner Länge für ein bestimmtes Schubelement einsetzbar ist, müssen für unterschiedlich tiefe Schubelemente auch entsprechend modifizierte Schienenpakete vorgehalten werden, mit integrierter Synchronführung.Since the said rail package can be used in each case only in terms of its length for a particular pusher, must for different depths pushers also correspondingly modified rail packages are kept, with integrated synchronous control.

Neben diesem vor allem betriebswirtschaftlichen Nachteil ist weiter zu beklagen, dass die bekannte Synchronführung nicht nachträglich in ein mit Schubelementen bestücktes Möbel eingebaut werden kann. Im Bedarfsfall muss hier zumindest das komplette Schienenführungs-System ausgetauscht werden, wenn nicht gar einschließlich des Schubelementes.In addition to this especially business disadvantage is further to complain that the known synchronous guide can not be retrofitted installed in a fitted with pusher furniture. If necessary, at least the complete rail guide system must be replaced here, if not including the push element.

Der Erfindung liegt die Aufgabe zugrunde, eine Synchronführung der gattungsgemäßen Art so weiterzuentwickeln, dass ihre Verwendungsfähigkeit mit geringem konstruktiven und fertigungstechnischen Aufwand verbessert wird.The invention has for its object to further develop a synchronous guide of the generic type so that their usefulness is improved with little design and manufacturing effort.

Diese Aufgabe wird durch eine Synchronführung mit den Merkmalen des Anspruchs 1 gelöst. Gemäß der gestellten Aufgabe ist die neue Synchronführung für unterschiedlichste Abmessungen von Schubelementen verwendbar, da die Zahnräder nun nicht mehr integraler Bestandteil des Schienensystems sind, sondern unabhängig davon am Möbelkorpus befestigt werden.This object is achieved by a synchronous guide with the features of claim 1. According to the stated object, the new synchronous guide for a variety of dimensions of push elements is used, since the gears are no longer an integral part of the rail system, but are independently attached to the furniture body.

Dies erlaubt auch eine nachträgliche Ausrüstung des Möbels mit einer Synchronführung, was naturgemäß mit einer für diesen Fall erheblichen Kostenersparnis verbunden ist.This also allows subsequent equipment of the furniture with a synchronous guide, which is naturally associated with a considerable cost saving for this case.

Eine vorteilhafte Weiterbildung der Erfindung sieht vor, dass der jeweilige Treibriemen schubstabil geführt ist, wozu bevorzugt eine Führungsleiste an der zugeordneten Korpuswange befestigt sein kann, die einen Führungsschlitz aufweist, in dem der Treibriemen bei einem Einschieben des Schubelementes gegen ein Knicken gesichert geführt ist.An advantageous development of the invention provides that the respective drive belt is guided shear stable, what preferably a guide bar can be attached to the associated carcass cheek having a guide slot in which the drive belt is guided secured against buckling during insertion of the thrust element.

Diese Führungsleiste dient zweckmäßigerweise auch der Lagerung des Zahnrades, mit dem der Treibriemen in Wirkverbindung steht. Dabei wird der Treibriemen im Bereich des Zahnrades vorzugsweise um 180° umgelenkt in Fortführung des Führungsschlitzes der Führungsleiste. Denkbar ist auch, den Treibriemen nach einer Umlenkung beispielsweise auf einer Rolle aufzuwickeln.This guide strip is expediently also the storage of the gear, with which the drive belt is in operative connection. In this case, the drive belt in the region of the toothed wheel is preferably deflected by 180 ° in continuation of the guide slot of the guide rail. It is also conceivable to wind the drive belt after a deflection, for example on a roll.

Zur Verringerung der Reibung kann der Treibriemen mit einer geeigneten Beschichtung versehen sein, z.B. mit PTFE. Alternativ besteht auch die Möglichkeit, bei der Herstellung des Treibriemens ein solches Mittel als integralen Bestandteil mit einzubringen.To reduce friction, the drive belt may be provided with a suitable coating, e.g. with PTFE. Alternatively, it is also possible to incorporate such an agent as an integral part in the production of the drive belt.

Zur Vermeidung bzw. Minimierung von Geräuschen besteht der Treibriemen bevorzugt aus einem Verbundwerkstoff. Hierzu kann ein Kunststoff mit Fasereinlage vorgesehen sein oder ein Verbund aus einem Material hoher Festigkeit, wie Metall, mit einem flexiblen Kunststoff.To avoid or minimize noise, the drive belt is preferably made of a composite material. For this purpose, a plastic can be provided with fiber insert or a composite of a high-strength material, such as metal, with a flexible plastic.

Durch die schubstabile Führung des Treibriemens kann auf einen wie auch immer gearteten, an dem der Anbindung des Treibriemens am Schubelement abgewandten Ende festgelegten Mitnehmer verzichtet werden, durch den eine Straffung des Treibriemens beim Einschieben des Schubelementes erfolgen müsste.Due to the shear-stable guidance of the drive belt can be dispensed with a whatsoever, on which the connection of the drive belt on the thrust element facing away fixed driver through which a tightening of the drive belt would have to be done when inserting the pusher.

Darüber hinaus kann der Treibriemen sozusagen als handelsübliche Rollenware auf das jeweils erforderliche Maß abgelängt werden, was ebenfalls zu einer Kostenreduzierung beiträgt.In addition, the drive belt can be cut to length, so to speak as a commercial roll goods to the extent required, which also contributes to a cost reduction.

Im Übrigen kann als Treibriemen jede geeignete Ausführungsvariante Verwendung finden. Beispielhaft seien hier ein Zahnriemen, eine Gliederkette oder ein Lochband genannt. Wesentlich ist, dass der Treibriemen, wie bereits aus dem Stand der Technik bekannt, formschlüssig mit dem Zahnrad in Eingriff steht.Incidentally, any suitable embodiment can be used as a drive belt. By way of example, a toothed belt, a link chain or a perforated belt may be mentioned here. It is essential that the drive belt, as already known from the prior art, is positively engaged with the gear.

Statt der erwähnten Lagerung des jeweiligen Zahnrades in einer Führungsleiste, besteht selbstverständlich auch die Möglichkeit, das Zahnrad in einem separaten Halter zu lagern, der entweder an der Korpuswange oder an der Korpusrückwand des Möbels befestigt wird.Instead of the mentioned storage of the respective gear in a guide bar, of course, there is also the possibility to store the gear in a separate holder which is attached either to the carcass or to the carcass back of the cabinet.

Die Anbindung des Treibriemens am Schubelement erfolgt zweckmäßigerweise über eine Halterung, die bevorzugt an der Rückwand des Schubelementes befestigt ist.The connection of the drive belt on the thrust element is expediently carried out via a holder, which is preferably fastened to the rear wall of the thrust element.

Als weiterer Vorteil der Erfindung ist zu erwähnen, dass durch die von den Auszugsschienen losgelöste Befestigung der Zahnräder im Zusammenspiel mit dem flexiblen Treibriemen ohne weiteres ein Ausgleich von relativ großen Fertigungstoleranzen des Möbelkorpus möglich ist, wie sie in der Möbelfertigung auftreten und akzeptiert werden. Daraus ergibt sich eine durchaus bemerkenswerte Verbesserung der Funktionssicherheit.Another advantage of the invention is to be mentioned that by the detachment of the pull-out rails of the gears in interaction with the flexible drive belt readily a balance of relatively large manufacturing tolerances of the furniture body is possible, as they occur in furniture production and accepted. This results in a quite remarkable improvement in functional reliability.

Die ortsfest gelagerte Koppelstange kann zum Ein- und Ausfahren des Schubelementes mit einem Antrieb versehen sein. Denkbar ist auch, an die Koppelstange eine Selbsteinzugsvorrichtung, z.B. in Form einer Rollfeder anzuschließen, wobei die Einfahrbewegung des Schubelementes durch einen mit der Koppelstange in Verbindung stehenden Rotationsdämpfer gedämpft werden kann.The stationary mounted coupling rod can be provided for driving in and out of the thrust element with a drive. It is also conceivable, to the coupling rod a Selbsteinzugsvorrichtung, e.g. to connect in the form of a scroll spring, wherein the retraction movement of the thrust element can be damped by a rotational damper in communication with the coupling rod.

Ein Ausstoßen des Schubelementes kann unter Zuhilfenahme bekannter Mechanismen, wie eines Kronenmechanismus, einer Herzkurve oder einer 3-D-Kurve oder einer Rollfeder erfolgen.Ejection of the pusher may be accomplished by the aid of known mechanisms, such as a crown mechanism, a cardiac curve, or a 3-D curve or a scroll spring.

Durch eine entsprechende Modifizierung der Synchronführung kann eine Auslaufsicherung für das Schubelement hergestellt werden.By a corresponding modification of the synchronous guide, an outlet safety device for the push element can be produced.

Weitere vorteilhafte Ausbildungen der Erfindung sind in den Unteransprüchen gekennzeichnet.Further advantageous embodiments of the invention are characterized in the subclaims.

Ein Ausführungsbeispiel der Erfindung wird nachfolgend anhand der beigefügten Zeichnungen beschrieben.An embodiment of the invention will be described below with reference to the accompanying drawings.

eine Einzelheit des Möbels in einer rückseitigen Ansicht, gleich-falls schaubildlich dargestellt.a detail of the furniture in a back view, also shown schematically.

In den Figuren 1 bis 4 ist ein Möbelkorpus 1 erkennbar, der eine Korpusrückwand 2 sowie zwei sich gegenüberliegende Korpuswangen 3 aufweist.In the FIGS. 1 to 4 a furniture body 1 can be seen, which has a carcass rear wall 2 and two opposing carcass cheeks 3.

In dem Möbelkorpus 1 ist schienengeführt ein Schubelement 4 verschiebbar gelagert, von dem lediglich ein umlaufender Rahmen gezeigt ist und der Bestandteil eines Schubkastens, Registerauszugs oder dergleichen sein kann.In the furniture body 1 rail-guided thrust element 4 is slidably mounted, of which only a peripheral frame is shown and may be part of a drawer, register extension or the like.

Während in den Figuren 1 und 3 das Schubelement 4 in den Möbelkorpus 1 eingeschoben dargestellt ist, geben die Figuren 2 und 4 eine ausgezogene Stellung wieder.While in the FIGS. 1 and 3 the pushing element 4 is shown inserted into the furniture body 1, give the Figures 2 and 4 an extended position again.

Hier ist deutlich zu erkennen, dass das Schubelement 4 über zwei sich gegenüberliegende Schienensysteme am Möbelkorpus 1 gelagert ist, von denen jedes aus einer mit der Korpuswange 3 fest verbundenen Führungsschiene 8, einer Mittelschiene 7 sowie einer Laufschiene 6 besteht, die mit einer Seitenwand des Schubelementes 4 verbunden ist oder integraler Bestandteil sein kann und die relativ zueinander bewegbar sind.Here it can be clearly seen that the thrust element 4 is mounted on two opposite rail systems on the furniture body 1, each of which consists of a firmly connected to the body panel 3 guide rail 8, a middle rail 7 and a running rail 6, with a side wall of the thrust element 4 is connected or may be an integral part and which are relatively movable.

Für eine gleichmäßige, d.h. synchrone Verschiebung des Schubelementes 4 ist eine Synchronführung 5 vorgesehen, die zwei am Möbelkorpus 1 unverrückbar positionierte Zahnräder 9 aufweist, die über eine sich quer zur Verschieberichtung des Schubelementes 4 erstreckende Koppelstange 10 miteinander verbunden sind, wobei an jedem der beiden Enden der Koppelstange 10 ein Zahnrad 9 verdrehsicher befestigt ist.For a uniform, ie synchronous displacement of the thrust element 4, a synchronous guide 5 is provided which has two immovably positioned on the furniture body 1 gears 9, which are connected via a transversely to the direction of displacement of the thrust element 4 extending coupling rod 10, wherein at each of the two ends the coupling rod 10 a gear 9 is secured against rotation.

Die Zahnräder 9 sind im rückwärtigen Bereich des Möbelkorpus 1 angeordnet und im vorliegenden Fall jeweils in einer Führungsleiste 12 gelagert, die parallel zur Führungsschiene 8 verlaufend an der zugeordneten Korpuswange 3 festgelegt ist.The gears 9 are arranged in the rear region of the furniture body 1 and stored in the present case in each case in a guide rail 12 which is fixed parallel to the guide rail 8 extending on the associated body panel 3.

Ein Treibriemen 11, der besonders deutlich in den Figuren 3 und 4 erkennbar ist, da hier auf die Darstellung der Führungsleiste 12 verzichtet ist, ist mit einem Ende am Schubelement 4 befestigt und zwar in einer Halterung 16, die an der Rückseite des Schubelementes 4 angeschlossen ist.A drive belt 11, which is particularly evident in the Figures 3 and 4 can be seen, since it is dispensed with the representation of the guide bar 12 is fixed with one end on the thrust element 4 and indeed in a holder 16 which is connected to the back of the thrust element 4.

Der Treibriemen 11 ist in einem Führungsschlitz 13 der Führungsleiste 12 schubstabil geführt, d.h., die Höhe des Führungsschlitzes 13 ist so bemessen, dass ein Knicken des Treibriemens 11 beim Einschieben des Schubelementes 4 verhindert wird.The drive belt 11 is guided stably in a guide slot 13 of the guide rail 12, that is, the height of the guide slot 13 is dimensioned so that a buckling of the drive belt 11 during insertion of the push element 4 is prevented.

Der Treibriemen 11 ist, ausgehend von der Halterung 16 in dem Führungsschlitz 13 bis in einen Verbindungsbereich mit dem Zahnrad 9 geführt, wo er unter Umlenkung um 180° in den im weiteren Verlauf parallel geführten Führungsschlitz 13 weitergeführt wird, in dem das praktisch lose Ende des Treibriemens 11 einliegt.The drive belt 11 is guided, starting from the holder 16 in the guide slot 13 into a connection region with the gear 9, where it is continued under deflection by 180 ° in the laterally guided in parallel guide slot 13, in which the practically loose end of Drive belt 11 rests.

Bei einem Ausziehen des Schubelementes 4 aus dem Möbelkorpus 1 wird demnach der Treibriemen 11 mitgezogen und gelangt so unter Umlenkung und Abstützung, bei gleichzeitiger Drehung des Zahnrades 9, mit dem der Treibriemen 11 in Eingriff steht, weitgehend aus dem in diesem Fall oberen Teil des Führungsschlitzes 13 in dessen dazu parallelen unteren Teil, wie in der Figur 4 erkennbar ist.Upon removal of the thrust element 4 from the furniture body 1, the drive belt 11 is thus pulled along and thus passes under deflection and support, with simultaneous rotation of the gear 9, with the drive belt 11 is engaged, largely from the upper part of the guide slot in this case 13 in its parallel lower part, as in the FIG. 4 is recognizable.

Da durch die Linearbewegung der Treibriemen 11 die kämmenden Zahnräder 9 in Drehung versetzt und diese durch die Koppelstange 10 verdrehsicher zueinander verbunden sind, ist der Bewegungsablauf sowohl der Treibriemen 11 wie auch der Zahnräder 9 synchron und damit die Auszugsbewegung des Schubelementes 4 insgesamt.As offset by the linear movement of the drive belt 11, the meshing gears 9 in rotation and these are connected by the coupling rod 10 against rotation to each other, the movement of both the drive belt 11 and the gears 9 is synchronous and thus the extension movement of the thrust element 4 total.

Erkennbar handelt es sich im Ausführungsbeispiel um einen sogenannten Überauszug, bei dem das Schubelement 4 in ausgezogener Stellung vor der Vorderseite des Möbelkorpus 1 positioniert ist. Um dem an der Halterung 16 befestigten Treibriemen 11 über das vordere Ende des Führungsschlitzes 13 hinaus eine Führung zu geben, ist in der Führungsleiste 12 eine entsprechend der Verfahrbewegung des Schubelementes 4 verschiebbare Führungsverlängerung 14 gelagert, die durch ein an der Halterung 16 befestigtes Druckstück 17 aus der Führungsleiste 12 in eine Endstellung verschoben wird, während bei einem Einschieben des Schubelementes 4 die Führungsverlängerung 14 durch eine angeschlossene Zugfeder 15, die andererseits an der Führungsleiste 12 befestigt ist, zurückgeholt wird.Visible in the exemplary embodiment is a so-called over extension, in which the thrust element 4 is positioned in the extended position in front of the front of the furniture body 1. To the attached to the bracket 16 drive belt 11 to give a guide beyond the front end of the guide slot 13, a corresponding to the movement of the thrust element 4 displaceable guide extension 14 is mounted in the guide bar 12, which is displaced by a fixed to the holder 16 pressure member 17 from the guide bar 12 in an end position while at an insertion of the thrust element 4, the guide extension 14 by a connected tension spring 15, which is on the other hand secured to the guide rail 12, is retrieved.

Der Treibriemen 11 ist aus einem in gewissem Maße eigensteifen, jedoch problemlos biegsamen Material hergestellt, beispielsweise einem geeigneten Kunststoff oder Metall.The drive belt 11 is made of a somewhat inherent stiff, but easily bendable material, for example, a suitable plastic or metal.
