Description

Die vorliegende Erfindung betrifft eine Auszugsführung nach dem Oberbegriff des Anspruches 1.The present invention relates to a pull-out guide according to the preamble of claim 1.

Die DE 199 45 781 offenbart eine Auszugsführung für einen Schubkasten, bei der ein Rotationsdämpfer vorgesehen ist. Der Rotationsdämpfer ist nicht über den gesamten Verfahrweg der Auszugsführung sondern lediglich im Bereich eines Selbsteinzuges wirksam. Der Rotationsdämpfer steht dabei seitlich von der Laufschiene hervor, so dass die Dämpfungseinrichtung nicht für Anwendungsfälle einsetzbar ist, bei denen ein kompakter Bauraum aufgrund beengter Platzverhältnisse notwendig ist.the DE 199 45 781 discloses a pull-out guide for a drawer, in which a rotary damper is provided. The rotation damper is not effective over the entire travel of the drawer runner but only in the area of a self-closing. The rotary damper protrudes laterally from the running rail, so that the damping device cannot be used for applications in which a compact installation space is required due to restricted space.

Die DE 11 2008 002 079 offenbart eine Konsolenbox, bei der ein Deckel verschiebbar an einem Boxkörper gelagert ist. Die Stabilität und die Führungsgenauigkeit bei der Lagerung einer solchen Abdeckung sind meistens begrenzt. Gerade bei Fahrzeugen kann es schnell zu Vibrationsgeräuschen kommen, wenn die Führung mit zu viel Spiel erfolgt.the DE 11 2008 002 079 discloses a console box in which a lid is slidably mounted on a box body. The stability and guidance accuracy when storing such a cover are usually limited. Vibrating noises can quickly occur in vehicles in particular if the guide is operated with too much play.

Die US 2011/0187254 offenbart eine Auszugsführung, die eine erste Laufschiene, eine zweite Laufschiene und eine dritte Laufschiene zwischen der ersten und der zweiten Laufschiene umfasst. Ferner ist eine Bremsvorrichtung vorgesehen, wobei ein erster Halterahmen auf der ersten Laufschiene fixiert ist, an dem eine Zahnstange angeordnet ist, und ein zweiter Halterahmen an der zweiten Laufschiene befestigt ist. An dem zweiten Halterahmen ist ein Dämpfer vorgesehen, der mit der Zahnstange in Eingriff steht.the US2011/0187254 discloses a drawer slide comprising a first runner, a second runner, and a third runner between the first and second runners. Furthermore, a braking device is provided, with a first holding frame being fixed on the first running rail, on which a toothed rack is arranged, and a second holding frame being fastened to the second running rail. A damper is provided on the second holding frame and engages with the rack.

Es ist daher die Aufgabe der vorliegenden Erfindung, eine Auszugsführung zu schaffen, die eine exakte und gedämpfte Führung der Laufschiene relativ zur Führungsschiene ermöglicht und zudem einen kompakten Aufbau besitzt.It is therefore the object of the present invention to create a pull-out guide that enables the running rail to be guided in an exact and cushioned manner relative to the guide rail and also has a compact structure.

Diese Aufgabe wird mit einer Auszugsführung mit den Merkmalen des Anspruches 1 gelöst.This problem is solved with a pull-out guide having the features of claim 1 .

Erfindungsgemäß ist eine Bremsvorrichtung vorgesehen, mittels der die Relativbewegung der Laufschiene zu der Führungsschiene gebremst werden kann und die zwischen der Laufschiene und der Führungsschiene angeordnet ist. Dadurch ergibt sich ein besonders kompakter Aufbau und die Ergonomie beim Bewegen der Laufschiene ist verbessert. Durch die Bremsvorrichtung wird eine Bewegung der Laufschiene abgebremst, was gerade beim Einsatz von Auszugsführungen in verschiedenen Anwendungsgebieten vorteilhaft ist, um zu schnelle Bewegungen eines geführten Bauteils in die Endlagen zu vermeiden. Dadurch werden Anschlaggeräusche und Vibrationen mindestens minimiert, wenn nicht sogar eliminiert. Zusätzlich wird die Lebensdauer des Systems durch den schonenden Effekt der erfindungsgemäßen Auszugsführung verlängert.According to the invention, a braking device is provided by means of which the movement of the running rail relative to the guide rail can be braked and which is arranged between the running rail and the guide rail. This results in a particularly compact structure and the ergonomics when moving the running rail is improved. A movement of the running rail is slowed down by the braking device, which is particularly advantageous when using pull-out runners in various areas of application, in order to prevent a guided component from moving too quickly into the end positions. As a result, impact noise and vibrations are at least minimized, if not eliminated. In addition, the service life of the system is extended by the gentle effect of the pull-out guide according to the invention.

Die erfindungsgemäße Auszugsführung kann beispielsweise in einem Möbel, insbesondere in einem Schubkastensystem, einem Haushaltsgerät, insbesondere in einer Dunststabzugshaube, oder in einem Fahrzeug, insbesondere im Interieurbereich, eingesetzt werden. Im Interieurbereich bietet sich vorzugsweise der Einsatz in einer Mittelkonsole, bei der eine über eine Auszugsführung gelagerte Abdeckung verfahrbar ist, an. Die Abdeckung kann zusätzlich als Armlehne ausgebildet sein und zum Abschluss eines verdeckten Behältnisses dienen. Auch andere Anwendungsfälle für die erfindungsgemäße Auszugsführung sind möglich.The pull-out guide according to the invention can be used, for example, in a piece of furniture, in particular in a drawer system, in a household appliance, in particular in an extractor hood, or in a vehicle, in particular in the interior area. In the interior area, the preferred option is to use it in a center console, in which a cover mounted on a pull-out guide can be moved. The cover can also be designed as an armrest and serve to close a concealed container. Other applications for the pull-out guide according to the invention are also possible.

Vorzugsweise ist die Bremsvorrichtung vollständig von der Laufschiene und der Führungsschiene umgeben. Die Laufschiene und die Führungsschiene können dabei leistenförmig ausgebildet sein und die Bremsvorrichtung umfassen.The braking device is preferably completely surrounded by the running rail and the guide rail. The running rail and the guide rail can be designed in the form of strips and can include the braking device.

Gemäß einer weiteren Ausgestaltung der Erfindung ist die Zahnstange der Bremsvorrichtung parallel zur Längsrichtung der Laufschiene ausgerichtet und an der Laufschiene oder der Führungsschiene festgelegt.According to a further embodiment of the invention, the toothed rack of the braking device is aligned parallel to the longitudinal direction of the running rail and fixed to the running rail or the guide rail.

Unter Führungselementen können Gleitelemente, Rollen, Wälzkörper oder ähnliches verstanden werden.Guide elements can be understood to mean sliding elements, rollers, rolling bodies or the like.

Für eine stabile Führung der Laufschiene an der Führungsschiene kann an gegenüberliegenden Längsseiten der Führungsschiene oder der Laufschiene ein C-förmiger Rand ausgebildet sein, an dem zwei beabstandete Bahnen von Wälzkörpern angeordnet sind, zwischen denen ein Steg der Laufschiene oder der Führungsschiene angeordnet ist. Durch die Anordnung der Wälzkörper in unterschiedlichen Bahnen wird eine verbesserte Führung erreicht, die auch eine Führung gegen Abheben oder in anderer Richtung senkrecht zur Längsrichtung der Laufschiene gewährleistet.For stable guidance of the running rail on the guide rail, a C-shaped edge can be formed on opposite longitudinal sides of the guide rail or the running rail, on which two spaced tracks of rolling bodies are arranged, between which a web of the running rail or the guide rail is arranged. By arranging the rolling elements in different tracks, improved guidance is achieved, which also ensures guidance against lifting off or in another direction perpendicular to the longitudinal direction of the running rail.

Für eine zuverlässige Verzögerung umfasst die Bremsvorrichtung mindestens ein drehbar gelagertes Zahnrad, das mit der Zahnstange in Eingriff steht und einen an einem Schlitten angeordneten Rotationsdämpfer antreibt. Dabei kann der Rotationsdämpfer über den gesamten Verfahrweg der Laufschiene wirksam sein, sofern sich die Zahnstange ebenfalls über den gesamten Weg der Laufschiene erstreckt.For reliable deceleration, the braking device comprises at least one rotatably mounted gear wheel which is in engagement with the toothed rack and drives a rotary damper arranged on a carriage. In this case, the rotation damper can be effective over the entire travel of the running rail, provided that the toothed rack also extends over the entire path of the running rail.

Um die Laufschiene zumindest in einer Endposition verrasten zu können, ist vorzugsweise an dem Schlitten eine Rastaufnahme ausgebildet, in die ein Rastelement bei Erreichen einer Endposition bis zur Überwindung einer Grenzkraft lösbar gehalten ist. Unter der Grenzkraft, wird diejenige Kraft verstanden, die zum Lösen des Rastelementes aus der Rastaufnahme überwunden werden muss. Vorzugsweise kann der Schlitten an gegenüberliegenden Seiten eine Rastaufnahme aufweisen, so dass in zwei gegenüberliegenden Endpositionen ein Verrasten ermöglicht wird. Als Rastelement kann beispielsweise ein Zapfen, Bolzen oder dergleichen vorgesehen sein, das in die Rastaufnahme am Schlitten einfügbar ist.In order to be able to lock the running rail at least in one end position, a locking receptacle is preferably formed on the carriage, in which a locking element is releasably held when an end position is reached until a limit force is overcome. The limit force is understood to mean that force which has to be overcome in order to release the locking element from the locking receptacle. The carriage can preferably have a latching receptacle on opposite sides, so that latching is made possible in two opposite end positions. A pin, bolt or the like can be provided as a locking element, for example, which can be inserted into the locking receptacle on the carriage.

Für eine einfache Montage der Auszugsführung kann der Schlitten mit dem Rotationsdämpfer an der Laufschiene oder der Führungsschiene festgelegt werden.For easy assembly of the drawer runner, the carriage can be fixed to the running rail or the guide rail with the rotation damper.

Der Rotationsdämpfer kann in unterschiedliche Bewegungsrichtungen eine gleichmäßige Bremskraft erzeugen, aber auch eine unterschiedliche Bremskraft erzeugen, beispielsweise durch Ausbildung eines Freilaufes. Als Rotationsdämpfer können bekannte Flüssigkeitsdämpfer eingesetzt werden, bei denen zwei relativ zueinander drehend bewegbare Teile vorgesehen sind, die über ein Dämpfungsmedium, beispielsweise Silikonöl, während einer Bewegung relativ zueinander gebremst werden.The rotary damper can generate a uniform braking force in different directions of movement, but also generate a different braking force, for example by forming a freewheel. Known liquid dampers can be used as rotary dampers, in which two parts are provided which can be rotated relative to one another and which are braked relative to one another during a movement by means of a damping medium, for example silicone oil.

Vorzugsweise sind Zahnstange und/oder das im Eingriff befindliche Zahnrad aus Kunststoff hergestellt, können allerdings bei höheren Belastungen auch aus anderen Materialien bestehen. Durch eine bestimmte Kunststoffkombination bzw. durch die Verwendung von Kunststoff mit eingelagertem Schmierstoff oder beschichteten Kunststoff (Gleitlacke etc.) kann der Verschleiß zusätzlich minimiert werden. Dadurch kann die Auszugsführung auch in Bereichen eingesetzt werden, in denen auf herkömmliche Schmierstoffe, Fette, Öle verzichtet werden muss, beispielsweise im hochwertigen Interieurbereich.The toothed rack and/or the gear wheel in engagement are preferably made of plastic, but can also be made of other materials in the case of higher loads. Wear can also be minimized by using a specific plastic combination or by using plastic with embedded lubricant or coated plastic (bonded coatings, etc.). As a result, the drawer runner can also be used in areas where conventional lubricants, greases and oils cannot be used, for example in high-quality interiors.

Eine Auszugsführung 1 umfasst eine festlegbare Führungsschiene 2 und eine verfahrbar gelagerte Laufschiene 3. Führungsschiene 2 und Laufschiene 3 können aus gebogenem Metallblech, insbesondere Stahlblech, hergestellt sein und beispielsweise an einer Mittelkonsole eines Fahrzeuges verbaut werden, um eine Abdeckung verschiebbar zu lagern.A pull-out guide 1 comprises a fixable guide rail 2 and a movably mounted running rail 3. The guide rail 2 and running rail 3 can be made of bent sheet metal, in particular sheet steel, and can be installed, for example, on a center console of a vehicle in order to slidably mount a cover.

Wie in den Figuren 2 und 3 gezeigt ist, ist für eine verschiebbare Lagerung der Laufschiene 3 eine Vielzahl von Führungselementen in Form von kugelförmigen Wälzkörpern 4 vorgesehen, die durch einen Wälzkörperkäfig 5 gehalten oder positioniert werden. Die Führungsschiene 2 ist leistenförmig ausgebildet und umfasst an gegenüberliegenden Seiten einen C-förmigen Rand 20, der einen oberen Schenkel 21, einen unteren Schenkel 22 sowie einen dazwischen ausgebildeten Bodenabschnitt 23 aufweist. Die beiden C -förmigen Ränder 20 sind über eine Verlängerung der Schenkel 22 miteinander verbunden. An dem Übergang zwischen dem Schenkel 21 bzw. 22 und dem Boden 23 sind gerundete Laufbahnen für die Wälzkörper 4 ausgebildet.As in the figures 2 and 3 is shown, a plurality of guide elements in the form of spherical rolling elements 4 are provided for a displaceable mounting of the running rail 3 , which are held or positioned by a rolling element cage 5 . The guide rail 2 is strip-shaped and comprises a C-shaped edge 20 on opposite sides, which has an upper leg 21, a lower leg 22 and a bottom section 23 formed between them. The two C -shaped edges 20 are connected to one another via an extension of the legs 22 . At the transition between the leg 21 or 22 and the bottom 23 rounded raceways for the rolling elements 4 are formed.

Die Laufschiene 3 umfasst einen leistenförmigen flachen Bodenabschnitt 30, an dem an gegenüberliegenden Seiten eine im Wesentlichen senkrecht hervorstehende Stufe 31 mit einem nach außen abgewinkelten Steg 32 angeordnet ist. Die auf gegenüberliegenden Seiten angeordneten Stege 32 erstrecken sich etwa parallel zum Boden 30. Die Stege 32 greifen zwischen die in zwei Bahnen angeordneten Wälzkörpern 4 ein, so dass die Laufschiene 3 auch in eine Richtung senkrecht zur Längsrichtung der Laufschiene 3 geführt ist.The running rail 3 comprises a strip-shaped flat bottom section 30 on which a substantially vertically projecting step 31 with an outwardly angled web 32 is arranged on opposite sides. The webs 32 arranged on opposite sides extend approximately parallel to the base 30. The webs 32 engage between the rolling bodies 4 arranged in two tracks, so that the running rail 3 is also guided in a direction perpendicular to the longitudinal direction of the running rail 3.

An der Führungsschiene 2 ist eine Zahnstange 6 form-, kraft- oder stoffschlüssig festgelegt. Die Zahnstange 6 steht im Eingriff mit einem Zahnrad 7, das einen Rotationsdämpfer 8 antreibt. Der Rotationsdämpfer 8 umfasst zueinander drehend bewegbare Teile, beispielsweise eine Trommel, die über ein Dämpfungsmedium bei einer Bewegung relativ zueinander gebremst werden. Die Gestaltung des Rotationsdämpfers kann variieren, beispielsweise kann die gleiche Bremskraft bei einer Bewegung in unterschiedliche Richtungen erzeugt werden, oder es kann in eine Richtung eine geringere Bremskraft, beispielsweise ein Freilauf, erzeugt werden. Der Rotationsdämpfer 8 ist an einem Schlitten 9 gehalten, der an der Laufschiene 3 festgelegt ist. Hierfür umfasst der Schlitten 9 mehrere Rastelelemente 10, die in Aussparungen 33 an der Laufschiene 3 verrastet werden können.A toothed rack 6 is fixed to the guide rail 2 in a positive, non-positive or material connection. The rack 6 is in engagement with a gear 7 which drives a rotary damper 8 . The rotary damper 8 comprises parts that can be rotated in relation to one another, for example a drum, which are braked via a damping medium when they move relative to one another. The design of the rotary damper can vary, for example the same braking force can be generated when moving in different directions, or a smaller braking force can be generated in one direction, for example freewheeling. The rotation damper 8 is held on a carriage 9 which is fixed to the running rail 3 . For this purpose, the carriage 9 includes a plurality of locking elements 10 which can be locked in recesses 33 on the running rail 3 .

Der Schlitten 9 ist aus einem elastischen Material, beispielsweise aus Kunststoff, hergestellt und umfasst an gegenüberliegenden Seiten Rastaufnahmen 13 und 14, die zur Begrenzung der Bewegung der Laufschiene 3 dienen und um diese in einer Endposition lösbar zu fixieren. Zum lösbaren Halten der Laufschiene 3 in den nachfolgend beschriebenen Endpositionen können Rastelemente 11 und 12 in Form von Zapfen in die Rastaufnahmen 13 und 14 aufgenommen werden, die an der Führungsschiene 2 festgelegt sind.The carriage 9 is made of an elastic material, for example plastic, and comprises latching receptacles 13 and 14 on opposite sides, which serve to limit the movement of the running rail 3 and to fix it in a detachable end position. For releasably holding the running rail 3 in the end positions described below, latching elements 11 and 12 in the form of pins can be accommodated in the latching receptacles 13 and 14 which are fixed to the guide rail 2 .

In Figur 4 ist der kompakte Aufbau der Auszugsführung 1 erkennbar. Die Bremsvorrichtung mit dem Schlitten 9, dem Rotationsdämpfer 8, dem Zahnrad 7 sowie der Zahnstange 6 ist zwischen der Führungsschiene 2 und der Laufschiene 3 vollständig aufgenommen. Für eine gute Führung greifen die Stege 32 an der Laufschiene 3 in den C-förmigen Rand 20 der Führungsschiene ein.In figure 4 the compact structure of the pull-out guide 1 can be seen. The braking device with the carriage 9, the rotary damper 8, the gear 7 and the rack 6 is completely accommodated between the guide rail 2 and the running rail 3. For good guidance, the webs 32 on the running rail 3 engage in the C-shaped edge 20 of the guide rail.

In den Figuren 5A bis 5C ist die Auszugsführung 1 in unterschiedlichen Positionen dargestellt. In Figur 5A ist die Laufschiene 3 in einer Mittelposition dargestellt, in der die Rastelelemente 11 und 12 beabstandet von dem Schlitten 9 angeordnet sind und die Laufschiene 3 in gegenüberliegende Richtungen bewegbar an der Führungsschiene 2 gehalten ist.In the Figures 5A to 5C the pull-out guide 1 is shown in different positions. In Figure 5A is the running rail 3 is shown in a middle position, in which the locking elements 11 and 12 are arranged at a distance from the carriage 9 and the running rail 3 is held on the guide rail 2 so that it can move in opposite directions.

Die Endpositionen sind dadurch gekennzeichnet, dass die Laufschiene 3 den maximalen Verfahrweg gegenüber der Führungsschiene 2 erreicht hat.The end positions are characterized in that the running rail 3 has reached the maximum travel distance relative to the guide rail 2 .

In Figur 5B ist eine erste Endposition gezeigt, bei der die Laufschiene 3 entlang der Führungsschiene 2 verfahren wurde, wobei durch die Drehung des Zahnrades 7 entsprechende Bremskräfte durch den Rotationsdämpfer 8 erzeugt wurden. Bei Erreichen der Endposition greift das Rastelement 12 in die Rastaufnahme 13 an dem Schlitten 9 ein, so dass die Laufschiene 3 lösbar in der ersten Endposition fixiert ist. Erst bei Überwindung der Grenzkräfte kann die Laufschiene 3 über die Mittelposition maximal bis in die zweite Endposition verfahren werden, die in Figur 5C gezeigt ist. In dieser Position befindet sich das Rastelement 11 in der Rastaufnahme 14 an der gegenüberliegenden Seite des Schlittens 9. Dadurch ist die Laufschiene 3 in einer geschlossenen Position ebenfalls an der Führungsschiene 2 lösbar fixiert. Die Höhe der Grenzkräfte in den Rastaufnahmen 13 und 14 sowie die Bremskräfte können je nach Anwendungsfall auch in den Endlagen und/oder Bewegungsrichtungen unterschiedlich eingestellt werden.In Figure 5B a first end position is shown, in which the running rail 3 was moved along the guide rail 2, with the rotation of the gearwheel 7 generating corresponding braking forces through the rotary damper 8. When the end position is reached, the locking element 12 engages in the locking receptacle 13 on the carriage 9, so that the running rail 3 is detachably fixed in the first end position. Only when the limit forces are overcome can the running rail 3 be moved beyond the middle position to the second end position, which is in Figure 5C is shown. In this position, the locking element 11 is located in the locking receptacle 14 on the opposite side of the carriage 9. As a result, the running rail 3 is also detachably fixed to the guide rail 2 in a closed position. The level of the limit forces in the locking receptacles 13 and 14 and the braking forces can also be set differently in the end positions and/or directions of movement, depending on the application.
