Description

Die Erfindung betrifft eine Vorrichtung zur Stabilisierung des Laufverhaltens eines in einem Möbelkorpus verfahrbaren Möbelteils, mit wenigstens einem Zahnrad, das mit wenigstens einer, ebenfalls zur Vorrichtung gehörenden Zahnstange bei der Ein- und Ausfahrbewegung des Möbelteils kämmt.The invention relates to a device for stabilizing the running behavior of a movable furniture body in a furniture part, with at least one gear wheel, which meshes with at least one, also belonging to the device rack in the retraction and extension of the furniture part.

Vorrichtungen zur Stabilisierung des Laufverhaltens eines in einem Möbelkorpus verfahrbaren Möbelteils sind bereits seit längerem bekannt. Derartige Vorrichtungen werden beispielsweise bei breiten Schubladen und/oder Schwerlast-Schubladen eingesetzt, um einen Seitenstabilisierung der Schublade zu erzielen, die ein seitliches Verkanten verhindert.Devices for stabilizing the running behavior of a movable in a furniture body furniture part have been known for some time. Such devices are used for example in wide drawers and / or heavy duty drawers to achieve a lateral stabilization of the drawer, which prevents lateral tilting.

Ein solches System ist beispielsweise aus der DE 20 2004 016 393 U1 bekannt. Die dort offenbarte Vorrichtung umfasst eine im hinteren Bereich des Schubladenkastens an dessen Seitenwand befestigte Zahnstange in die ein im hinteren Bereich der Schublade angeordnetes Zahnrad beim Einschieben der Schublade in Eingriff gelangt. Es ist dort offenbart, an den beiden einander gegenüberliegenden Seitenwänden des Schubladenkastens jeweils eine Zahnstange anzubringen, die mit jeweils einem am hinteren Bereich der Schublade angeordneten Zahnrad kämmt, wobei die Zahnräder über eine Synchronisationsstange miteinander gekoppelt sind. Eine derartige Anordnung gewährleistet nach dem Einspuren der Zahnräder in die zugeordnete Zahnstange eine Seitenstabilisierung der Schublade verbunden mit einer Stabilisierung des Laufverhaltens. Um das Laufverhalten weiter zu verbessern schlägt die vorgenannte Druckschrift vor, die Synchronisationsstange in einem Lager an der Schubladen-Rückwand zu lagern, wodurch die Schublade zur Synchronisationsstange höhenverstellbar ist.Such a system is for example from the DE 20 2004 016 393 U1 known. The device disclosed therein comprises a toothed rack mounted in the rear region of the drawer box on the side wall thereof into which a toothed wheel arranged in the rear region of the drawer engages upon insertion of the drawer. It is there disclosed, in each case a rack to install on the two opposite side walls of the drawer box, which meshes with a gear arranged at the rear of the drawer gear, wherein the gears are coupled together via a synchronization rod. Such an arrangement ensures after the meshing of the gears in the associated rack side stabilization of the drawer connected with a stabilization of the running behavior. In order to further improve the running behavior, the aforementioned document proposes to store the synchronization rod in a bearing on the drawer rear wall, whereby the drawer to the synchronization rod is height-adjustable.

Eine ähnliche Vorrichtung ist aus der DE 202 009 016 105 U1 bekannt.A similar device is from the DE 202 009 016 105 U1 known.

Ein Problembereich dieser Vorrichtungen ist der Einfädelbereich, also der in Einfahrrichtung des Möbelauszugs vordere Bereich der Zahnstange. In diesem Bereich wird das zugeordnete Zahnrad in die Zahnstange eingefädelt bzw. eingespurt. Dabei kann es zur Verklemmung zwischen Zahnrad und Zahnstange kommen, beispielsweise dann wenn der betreffende Zahn nicht die zugeordnete Lücke zwischen zwei benachbarten Zähnen der Zahnstange findet.A problem area of these devices is the threading area, that is, the front of the rack in the retraction direction of the furniture drawer. In this area, the assigned gear is threaded into the rack or eingespurt. This can lead to jamming between gear and rack, for example, if the tooth in question does not find the associated gap between two adjacent teeth of the rack.

Aufgabe der Erfindung ist es daher, eine Vorrichtung zur Stabilisierung des Laufverhaltens eines in einem Möbelkorpus verfahrbaren Möbelteils zu schaffen, die eine gegenüber den Vorrichtungen aus dem Stand der Technik weniger störanfällige Bedienung des verfahrbaren Möbelteils ermöglicht.The object of the invention is therefore to provide a device for stabilizing the running behavior of a movable furniture body in a furniture part, which allows a comparison with the devices of the prior art less susceptible to interference operation of the movable furniture part.

Die Aufgabe wird durch eine Vorrichtung zur Stabilisierung des Laufverhaltens eines in einem Möbelkorpus verfahrbaren Möbelteils mit den Merkmalen des unabhängigen Anspruchs 1 gelöst. Weiterbildungen der Erfindung sind in den Unteransprüchen dargestellt.The object is achieved by a device for stabilizing the running behavior of a movable in a furniture body furniture part having the features of independent claim 1. Further developments of the invention are shown in the subclaims.

Eine Vorrichtung gemäß dem Oberbegriff des Anspruchs 1 ist aus der GB 637983 bekannt.A device according to the preamble of claim 1 is known from GB 637983 known.

Die erfindungsgemäße Vorrichtung zur Stabilisierung des Laufverhaltens eines in einem Möbelkorpus verfahrbaren Möbelteils, wobei die Zahnstange einen Einfädelbereich zum Einfädeln des Zahnrads aufweist, in dem sich wenigstens ein in Längsrichtung der Zahnstange relativ zum Rest der Zahnstange beweglicher Zahn befindet, zeichnet sich dadurch aus, dass der bewegliche Zahn über ein Gelenk am Rest der Zahnstange gelagert ist. Der bewegliche Zahn kann also bei Bedarf über das Gelenk, das auch als Scharnier bezeichnet werden kann, eine Schwenkbewegung durchführen und daher zum besseren Einfädeln des Zahnrads wegschwenken.The inventive device for stabilizing the running behavior of a moveable in a furniture body furniture part, wherein the rack has a Einfädelbereich for threading the gear, in which is at least one movable in the longitudinal direction of the rack relative to the rest of the rack tooth, characterized in that the movable tooth is mounted via a hinge on the remainder of the rack. The movable tooth can thus perform a pivoting movement as needed via the joint, which can also be referred to as a hinge, and therefore pivot away for better threading of the gear.

Durch die Beweglichkeit des wenigstens einen Zahns im Einfädelbereich der Zahnstange lässt sich das zugeordnete Zahnrad besser einfädeln, da es beispielsweise möglich ist, dass die Zahnlücke zwischen zwei benachbarten Zähnen an der Zahnstange vergrößert wird, wodurch der zugeordnete Zahn des Zahnrads einfacher in die erste Zahnlücke hinein rutschen kann. Dadurch wird eine Verklemmung beim Einfädeln des Zahnrads verhindert.Due to the mobility of the at least one tooth in the threading of the rack, the associated gear can be better threaded, since it is possible, for example, that the tooth gap between two adjacent teeth on the rack is increased, whereby the associated tooth of the gear easier in the first tooth gap can slip. As a result, jamming during threading of the gear is prevented.

Bei einer Weiterbildung der Erfindung ist der bewegliche Zahn gegenüber dem Rest der Zahnstange nachgiebig gelagert, so dass er beim Einfädeln aus einer Grundstellung heraus und danach in diese zurückbewegbar ist. Somit stoßen beim Einfädeln keine zwei starren Bauteile, nämlich Zahnstange einerseits und Zahnrad andererseits, wie beim Stand der Technik aneinander, sondern die Zahnstange ist im Einfädelbereich nachgiebig, wobei sich der bewegliche Zahn bei Bedarf wegbiegen kann.In a further development of the invention, the movable tooth is resiliently mounted relative to the rest of the rack so that it can be moved back out of a basic position during threading and then into it. Thus, when threading do not encounter two rigid components, namely rack on the one hand and gear on the other hand, as in the prior art to each other, but the rack is compliant in Einfädelbereich, wherein the movable tooth can bend away when needed.

Besonders bevorzugt handelt es sich bei dem Gelenk bzw. Scharnier um ein Festkörpergelenk bzw. Festkörperscharnier. Das Gelenk ist also in diesem Fall kein separates Bauteil, sondern besteht aus dem Material der Zahnstange. Das Festkörpergelenk kann beispielsweise durch eine Materialschwächung des Zahnstangenmaterials am Zahngrund zwischen zwei benachbarten Zähnen der Zahnstange gebildet werden.The hinge or hinge is particularly preferably a solid-body joint or solid-state hinge. The joint is thus in this case no separate component, but consists of the material of the rack. The solid-state joint can be achieved, for example, by weakening the material of the rack material are formed at the tooth bottom between two adjacent teeth of the rack.

Bei einer Weiterbildung der Erfindung sind wenigstens zwei Zahnräder vorgesehen, denen jeweils eine Zahnstange zugeordnet ist, wodurch wenigstens zwei Zahnrad/Zahnstangen-Paare gebildet sind.In a further development of the invention, at least two gears are provided, each of which is associated with a rack, whereby at least two gear / rack pairs are formed.

In besonders bevorzugter Weise sind die beiden Zahnräder über eine Welle bewegungsgekoppelt. Die beiden Zahnräder können über die Welle gegenseitig mitdrehbar miteinander gekoppelt sein. Über die Welle lassen sich die beiden Zahnräder miteinander synchronisieren. Die Welle könnte daher auch als Synchronisationswelle bezeichnet werden.In a particularly preferred manner, the two gears are motion-coupled via a shaft. The two gears can be coupled to each other via the shaft rotatable together. The two gears can be synchronized with each other via the shaft. The wave could therefore also be called a synchronization wave.

In bevorzugter Weise besteht die Zahnstange aus Kunststoff, wobei der bewegliche Zahn eine geringere Biegesteifigkeit besitzt als der Rest der Zahnstange. Bei der Herstellung der Zahnstange aus Kunststoff lässt sich ein vorerwähntes Festkörpergelenk in besonders einfacher Weise herstellen. Die Biegesteifigkeit des beweglichen Zahns wird hierbei durch das Festkörpergelenk festgelegt. Alternativ wäre es jedoch auch möglich, dass die Zahnstange aus Holz oder Metall besteht. Es ist möglich, dass der wenigstens eine bewegliche Zahn aus einem anderen Material als die Zahnstange besteht. Der wenigstens eine bewegliche Zahn könnte beispielsweise aus Gummi bestehen.Preferably, the rack is made of plastic, wherein the movable tooth has a lower bending stiffness than the rest of the rack. In the production of the rack made of plastic, a aforementioned solid-state joint can be produced in a particularly simple manner. The bending stiffness of the movable tooth is determined by the solid-state joint. Alternatively, it would also be possible for the rack to be made of wood or metal. It is possible that the at least one movable tooth is made of a different material than the rack. The at least one movable tooth could for example consist of rubber.

Die Erfindung umfasst ferner ein Möbel, mit einem in einem Möbelkorpus verfahrbaren Möbelteil, das sich durch eine Vorrichtung nach einem der Ansprüche 1 bis 7 auszeichnet.The invention further comprises a piece of furniture, with a movable in a furniture body furniture part, which is characterized by a device according to one of claims 1 to 7.

Zweckmäßigerweise befindet sich das wenigstens eine Zahnrad am verfahrbaren Möbelteil, während die wenigstens eine Zahnstange am Möbelkorpus ausgebildet ist. Es ist jedoch alternativ möglich, die Zahnstange am verfahrbaren Möbelteil und das wenigstens eine Zahnrad am Möbelkorpus anzubringen. Ferner wäre es möglich, die Zahnstange an einem Adapterteil, beispielsweise Adapterwinkel, oder an einer Führungseinrichtung für das verfahrbare Möbelteil, beispielsweise einer Korpusschiene, anzubringen.Conveniently, there is at least one gear on the movable furniture part, while the at least one rack is formed on the furniture body. However, it is alternatively possible to attach the rack on the movable furniture part and the at least one gear on the furniture body. Furthermore, it would be possible to attach the rack to an adapter part, for example adapter angle, or to a guide device for the movable furniture part, for example a carcass rail.

In besonders bevorzugter Weise handelt es sich bei dem verfahrbaren Möbelteil um eine Schublade, Tür oder Klappe.In a particularly preferred manner, the movable furniture part is a drawer, door or flap.

Die Führungseinheit 15 besitzt im Beispielsfall eine an der Seitenwand 16 des Schubladenkastens befestigte Korpusschiene 18 und eine der Schublade zugeordnete, unterhalb des Schubladen-Bodens in Tiefenrichtung verlaufende Auszugschiene 19. Zwischen der Korpusschiene 18 und der Auszugschiene 19 ist ferner eine Mittelschiene 20 angeordnet die sowohl relativ beweglich zur Korpusschiene als auch relativ beweglich zur Auszugschiene 19 geführt ist. Eine derartige, aus Korpusschiene 18, Auszugschiene 19 und Mittelschiene 20 aufgebaute Führungseinheit 15 wird auch als Vollauszug bezeichnet. Es ist selbstverständlich möglich, auch Führungseinheiten 15 ohne Mittelschienen einzusetzen.The guide unit 15 has in the example a fixed to the side wall 16 of the drawer body rail 18 and one of the drawer associated below the drawer bottom extending in the depth direction drawer rail 19 between the carcass rail 18 and the drawer rail 19, a middle rail 20 is further arranged both relatively movable to the carcass rail and relatively movable to the slide rail 19 is guided. Such, from carcass rail 18, slide rail 19 and middle rail 20 constructed guide unit 15 is also referred to as full extension. It is of course possible to also use guide units 15 without middle rails.

Die Vorrichtung 11 dient zur Stabilisierung des Lauferhaltens der im Schubladenkasten verfahrbaren Schublade. Hierzu ist die Vorrichtung 11 mit wenigstens einem Zahnrad 21 ausgestattet, dass mit wenigstens einer, ebenfalls zur Vorrichtung 11 gehörenden Zahnstange 22 kämmt.The device 11 serves to stabilize the running of the movable drawer in the drawer box. For this purpose, the device 11 is equipped with at least one gear 21 that meshes with at least one, also belonging to the device 11 rack 22.

Im dargestellten Beispielsfall der Figur 1 sind zwei Zahnstangen 22 vorgesehen, von denen jedoch nur eine gezeigt ist. Die Zahnstangen 22 sind an den einander gegenüberliegenden Seitenwänden 16 des Schubladenkastens befestigt. Die Zahnstangen 22 sind im Beispielsfall im Querschnitt als Winkelprofile ausgestaltet und besitzen einen Montageschenkel 23 zur Befestigung an der zugeordneten Seitenwand 16 des Schubladenkastens 17. Dazu sind im Montageschenkel 23 in Zahnstangen-Längsrichtung hintereinander angeordnete Montagelöcher 24 vorgesehen, über die geeignete Befestigungsmittel in das Material, vorzugsweise Holzmaterial, der Seitenwand 16 eingetrieben werden können. Die Zahnstange 22 umfasst ferner einen winkelig zum Montageschenkel 23 angeordneten Zahnschenkel 25, an dem eine Zahnreihe 26 mit einer Vielzahl von in Zahnstangen-Längsrichtung hintereinander angeordneten Zähnen 27 ausgebildet ist.In the illustrated example of the FIG. 1 two racks 22 are provided, but only one of which is shown. The racks 22 are attached to the opposite side walls 16 of the drawer box. The racks 22 are configured in the example in cross-section as angle profiles and have a mounting leg 23 for attachment to the associated side wall 16 of the drawer box 17. For this purpose in the mounting leg 23 in rack longitudinal direction successively arranged mounting holes 24 are provided on the appropriate fastening means in the material, preferably wood material, the side wall 16 can be driven. The rack 22 further comprises an angle to the mounting leg 23 arranged tooth leg 25 on which a row of teeth 26 is formed with a plurality of longitudinally arranged in rack longitudinal direction teeth 27.

Die Zahnstange 22 besteht beispielsweise aus Kunststoffmaterial, wodurch die Zähne 27 gleich bei der Herstellung der Zahnstange 22 mit angeformt werden könnten.The rack 22 is for example made of plastic material, whereby the teeth 27 could be formed with the same in the manufacture of the rack 22 with.

Wie in Figur 1 gezeigt, zeigen die Zähne 27 am Zahnschenkel 25 der Zahnstange 22 im montierten Zustand nach unten in Richtung des Schubladenkasten-Bodens.As in FIG. 1 shown, the teeth 27 on the toothed leg 25 of the rack 22 in the mounted state downwards in the direction of the drawer bottom.

Wie weiter in Figur 1 dargestellt, ist jeder Zahnstange 22 ein Zahnrad 21 zugeordnet, das im Beispielsfall an der Schubladen-Rückwand 28 angeordnet ist. In Figur 1 ist wiederum nur ein Zahnrad 21 dargestellt, jedoch befindet sich auf der entgegengesetzten Seite der Schublade ein weiteres Zahnrad 21, das der dort an der Seitenwand des Schubladenkastens angebrachten und ebenfalls nicht dargestellten Zahnstange 22 zugeordnet ist. Die beiden Zahnräder 21 sind über eine Welle gegenseitig mitdrehbar miteinander bewegungsgekoppelt. Dadurch wird eine Synchronisation der beiden Zahnrad/Zahnstangen-Paare erzielt. Die Welle, die auch als Synchronisationswelle 29 bezeichnet werden kann, ist an einer Halterung 30 an der Schubladen-Rückwand 28 höhenverstellbar gelagert.As in further FIG. 1 shown, each rack 22 is associated with a gear 21, which is arranged on the drawer rear wall 28 in the example.

Wie in Figur 2 in Zusammenhang mit einem weiteren Ausführungsbeispiel der Vorrichtung 11 gezeigt, besitzt die Zahnstange 22 einen in Einschubrichtung der Schublade am vorderen Bereich der Zahnstange 22 ausgebildeten Einfädelbereich 31. An diesem Einfädelbereich 31 wird das zugeordnete Zahnrad 21 eingefädelt bzw. eingespurt und kämmt danach mit den Zähnen 27 der Zahnstange 22. Beim Einfädeln des Zahnrads 21 auf die Zahnstange 22 kann es bei herkömmlichen Vorrichtungen 11 zu Problemen kommen, derart, dass der zugeordnet Zahn 32 am Zahnrad 21 nicht die erforderliche erste Zahnlücke zwischen zwei benachbarten Zähnen 27 an der Zahnstange 22 findet und daher nicht richtig einfädelt. Dadurch kann es zu Verklemmungen kommen, die das Einschieben der Schublade behindern.As in FIG. 2 shown in connection with a further embodiment of the device 11, the rack 22 has a direction of insertion of the drawer at the front region of the rack 22 threading portion 31. At this Einfädelbereich 31, the associated gear 21st Threaded and meshes with the teeth 27 of the rack 22. When threading the gear 21 on the rack 22, it can cause problems in conventional devices 11, such that the associated tooth 32 on the gear 21 is not the required first tooth gap between two adjacent teeth 27 on the rack 22 and therefore does not thread properly. This can lead to jamming, which hinder the insertion of the drawer.

Um diesem Problem abzuhelfen, befindet sich im Einfädelbereich 31 der Zahnstange 22 mindestens ein in Längsrichtung der Zahnstange 22 relativ zum Rest der Zahnstange beweglicher Zahn 27a.To remedy this problem, located in the threading portion 31 of the rack 22 at least one in the longitudinal direction of the rack 22 relative to the rest of the rack movable tooth 27 a.

Im Beispielsfall ist der bewegliche Zahn 27a gegenüber dem Rest der Zahnstange 22 nachgiebig gelagert, so dass er beim Einfädeln aus einer Grundstellung heraus und danach in diese zurückbewegbar ist. Die in Figur 2 strichpunktiert gezeigte Stellung des beweglichen Zahns 27a ist eine mögliche Einfädelstellung, die der bewegliche Zahn 27a von der Grundstellung aus einnehmen kann.In the example, the movable tooth 27a is resiliently mounted relative to the rest of the rack 22 so that it can be moved back out of a basic position during threading and then into it. In the FIG. 2 Position of the movable tooth 27a shown in phantom is a possible threading position that the movable tooth 27a can assume from the basic position.

Im Beispielsfall ist der bewegliche Zahn 27a über ein als Festkörpergelenk ausgebildetes Gelenk 33 schwenkbeweglich gelagert, so dass er beispielsweise die in Figur 2 strichpunktiert dargestellte Stellung einnehmen kann. Ein solches Festkörpergelenk kann bei aus Kunststoff bestehenden Zahnstangen durch eine Materialschwächung des am Grund der zwischen zwei benachbarten Zähnen 27a, 27 ausgebildeten Zahnlücke befindlichen Zahnstangenmaterials in einfacher Weise ausgebildet werden.In the example case, the movable tooth 27a is pivotally mounted via a joint 33 designed as a solid-body joint, so that it can be moved, for example, into the joint FIG. 2 can take dash-dotted line position. Such a solid-state joint can be easily formed in plastic racks by weakening the material of the rack at the bottom of the tooth gap formed between two adjacent teeth 27a, 27.

Beim Einschieben der Schublade kommt also das Zahnrad 21 mit dem beweglichen Zahn 27a am Einfädelbereich der Zahnstange 22 in Kontakt, wodurch beispielsweise ein Zahn 32 am Zahnrad 21 den beweglichen Zahn 27a an der Zahnstange 22 wegbiegen, beispielsweise nach oben biegen kann, so dass der Zahn 32 am Zahnrad 21 in einfacher Weise in die zugeordnete erste Zahnlücke zwischen zwei benachbarten Zähnen 27a, 27 an der Zahnstange 22 einrastet bzw. einschnappt, wodurch das Zahnrad 21 eingefädelt ist.When inserting the drawer thus comes the gear 21 with the movable tooth 27a at the threading of the rack 22nd in contact, whereby, for example, a tooth 32 on the toothed wheel 21 can bend away the movable tooth 27a on the toothed rack 22, for example, upward, so that the tooth 32 on the toothed wheel 21 can easily fit into the associated first tooth gap between two adjacent teeth 27a, 27th engages or snaps on the rack 22, whereby the gear 21 is threaded.
