Description

Die Erfindung betrifft eine Ausziehführung für Schubladen.The invention relates to a pull-out for drawers.

Schubladen, beispielsweise bei Küchenmöbeln, werden üblicherweise so geführt, dass sie vollständig herausgezogen werden können. Zu diesem Zweck ist an jeder Seite der Schublade eine Schubladenführung angeordnet, die eine mit dem Korpus oder der Schrankwand verbundene Korpusschiene und eine mit der Schublade verbundene oder verbindbare Auszugsschiene aufweist. Um die Schublade vollständig herausziehen zu können, reicht die Verstellmöglichkeit dieser beiden Schienen aber nicht aus, so dass zwischen ihnen eine Mittelschiene angeordnet ist. Um sicherzustellen, dass die Mittelschiene ihre korrekte Position im Lauf der Zeit nicht verliert, sind Steuereinrichtungen vorhanden. Zwischen der Korpusschiene und der Mittelschiene einerseits und der Mittelschiene und der Auszugsschiene andererseits sind Tragrollen vorhanden, die nicht nur die leichte Verschiebung gewährleisten sollen, sondern auch das Gewicht der Schublade tragen müssen.Drawers, for example, in kitchen furniture, are usually performed so that they can be completely pulled out. For this purpose, a drawer guide is arranged on each side of the drawer, which has a connected to the body or cabinet wall cabinet rail and connected to the drawer or connectable drawer rail. In order to pull out the drawer completely, but the adjustment of these two rails is not enough, so that between them a middle rail is arranged. To ensure that the center rail does not lose its correct position over time, control devices are provided. Between the carcass rail and the center rail on the one hand and the center rail and the puller rail on the other hand support rollers are available, which should not only ensure the slight shift, but also have to carry the weight of the drawer.

Ein Beispiel einer Steuereinrichtung für eine Ausziehführungsgarnitur ( DE 203 07 757 U1 ) verwendet ein als Zahnrad ausgebildetes Steuerrad, das mit einer Zahnstange an der Korpusschiene und einer Zahnstange an der Ausziehschiene kämmt. Das Steuerrad kann auch als Reibrad ausgebildet sein. In diesem Fall ist es aus einem nachgiebigen Material gefertigt und weist einen Durchmesser auf, der größer ist als der Abstand zwischen den Laufprofilen der Korpus- und Ausziehschiene.An example of a control device for a Ausziehführungsgarnitur ( DE 203 07 757 U1 ) uses a gear designed as a steering wheel, which meshes with a rack on the carcass rail and a rack on the pull-out rail. The steering wheel can also be designed as a friction wheel. In this case, it is made of a resilient material and has a diameter which is greater than the distance between the barrel profiles of the carcass and pull-out rail.

Bei den das Gewicht der Schublade tragenden Trag- und Laufrollen ist es bekannt ( AT 40 62 20 B , AT 40 50 10 B ), in der Lauffläche der Rolle einen aus einem weicheren Material bestehenden Vorsprung anzubringen, der beispielsweise in eine Umfangsnut eingespritzt ist. Bei zunehmender Belastung verformt sich dieser Umfangsvorsprung so, dass dann die härtere Lauffläche der Rolle zum Einsatz kommt.In the weight of the drawer bearing support and rollers, it is known ( AT 40 62 20 B . AT 40 50 10 B ), in the tread of the roller to attach a made of a softer material projection, which is injected for example in a circumferential groove. As the load increases, this circumferential projection deforms so that the harder running surface of the roller is then used.

Weiterhin ist eine Schubladenöffnung mit drei Schienen bekannt, bei der an der mittleren Schiene eine Steuerrolle 18 gelagert ist, die eine Nabe und einen Reifen aus Gummi aufweist. Die Nabe weist zwei in ihrem Endbereich ausgebildete Flansche auf, zwischen denen sich der aus Gummi bestehende Reifen erstreckt ( US 4,737,039 ). Weitere Ausführungen sind aus den Schriften FR 2 441 086 ,
EP 1 486 632 und AT 402 599 B bekannt.Furthermore, a drawer opening with three rails is known, in which on the central rail a control roller 18 is mounted, which has a hub and a tire made of rubber. The hub has two flanges formed in its end region, between which the tire made of rubber extends ( US 4,737,039 ). Other versions are from the writings FR 2 441 086 .
EP 1 486 632 and AT 402 599 B known.

Der Erfindung liegt die Aufgabe zu Grunde, eine Ausziehführung für Schubladen im Hinblick auf verbesserte Laufeigenschaften, insbesondere auch eine Verringerung des Laufgeräuschs, weiter zu verbessern.The object of the invention is to further improve a pull-out guide for drawers with regard to improved running properties, in particular a reduction in running noise.

Zur Lösung dieser Aufgabe schlägt die Erfindung eine Ausziehführung mit den im Anspruch 1 genannten Merkmalen vor. Weiterbildungen der Erfindung sind Gegenstand von Unteransprüchen.To solve this problem, the invention proposes a pull-out with the features mentioned in claim 1. Further developments of the invention are the subject of dependent claims.

Die Korpusschiene, auch Tragschiene genannt, wird mit dem Korpus des Schranks verbunden. Die Last der Schublade wird von den Tragrollen zwischen Korpusschiene und Mittelschiene einerseits und Mittelschiene und Auszugsschiene andererseits getragen. Die an der Mittelschiene drehbar gelagerte Steuerrolle dient ausschließlich dazu, die Position und Bewegung der Mittelschiene mit dem Auszug- und Einschiebevorgang der Schublade zu synchronisieren.The carcass rail, also called support rail, is connected to the carcass of the cabinet. The load of the drawer is supported by the support rollers between the trunk rail and middle rail on the one hand and the middle rail and drawer rail on the other. The rotatably mounted on the center rail control roller is used exclusively to synchronize the position and movement of the center rail with the extension and insertion process of the drawer.

Um unter allen Umständen einen leisen nicht ratternden Lauf zu ermöglichen, ist erfindungsgemäß vorgesehen, dass eine Welle, auf der die Steuerrolle gelagert ist, einen von der Kreisform abweichenden Querschnitt mit einem in Auszugsrichtung größeren Durchmesser aufweist. Dadurch wird eine gewisse Möglichkeit des Ausgleichs der Position der Steuerrolle In der Richtung zwischen den beiden Schienen, mit denen sie In Eingriff steht, ermöglicht, ohne dass ein Spiel in Auszugsrichtung zugelassen wird. Es hat sich nämlich herausgestellt, dass diese Möglichkeit zu einer dauerhaften leisen Lagerung führt.In order to enable a quiet, non-rattling running under all circumstances, the invention provides that a shaft on which the control roller is mounted, having a deviating from the circular cross section with a larger diameter in the extension direction. Thereby, a certain possibility of compensating the position of the control roller in the direction between the two rails, with which it is engaged, allows, without a play in the extension direction is allowed. It has been found that this possibility leads to a permanent quiet storage.

Erfindungsgemäß ist vorgesehen, dass die Steuerrolle einen tragenden Teil als Hartkörper und einen diesem gegenüber in radialer Richtung mindestens teilweise vorspringenden Weichkörper aufweist. Dieser Weichkörper erstreckt sich vorzugsweise als Rings um den gesamten Umfang der Steuerrolle, ist aber vorzugsweise nur über einen Teil der axialen Erstreckung des Hartkörpers vorhanden, sozusagen als Ringvorsprung.According to the invention, it is provided that the control roller has a load-bearing part as a hard body and a soft body at least partially projecting in the radial direction. This soft body preferably extends as rings around the entire circumference of the control roller, but is preferably present only over part of the axial extent of the hard body, so to speak as an annular projection.

Als besonders günstig hat sich herausgestellt, wenn der Weichkörper Im Bereich nur einer axialen Stirnseite der Steuerrolle angeordnet ist.It has proven to be particularly favorable when the soft body is arranged in the region of only one axial end face of the control roller.

In Weiterbildung der Erfindung kann vorgesehen sein, dass die Steuerrolle in Zweikomponentenbauweise ausgebildet ist, insbesondere mit der Materialpaarung Kunststoff - Metall oder auch als Kombination aus Zink und Stahl.In a further development of the invention can be provided that the control roller is designed in two-component construction, in particular with the material pairing plastic - metal or as a combination of zinc and steel.

Es ist aber ebenfalls möglich und liegt im Rahmen der Erfindung, dass der Hartkörper und der Weichkörper zwei getrennte vor der Montage der Steuerrolle zusammengesetzte Bauteile sind. Dabei kann der Weichkörper auch lose an dem Hartkörper angebracht sein.However, it is also possible and within the scope of the invention that the hard body and the soft body are two separate components assembled before the assembly of the control roller. In this case, the soft body may also be attached loosely to the hard body.

Erfindungsgemäß ist vorgesehen, dass der Weichkörper zwischen einer Schulter des Hartkörpers und einer Lagerung der Steuerrolle angeordnet ist. Auf diese Weise lässt sich die Kombination aus Hartkörper und Weichkörper sehr einfach und kostengünstig herstellen.According to the invention, it is provided that the soft body is arranged between a shoulder of the hard body and a bearing of the control roller. In this way, the combination of hard body and soft body can be produced very easily and inexpensively.

Es ist ebenfalls möglich, dass der Weichkörper zwischen einer Schulter des Hartkörpers und einer Sicherungsscheibe festgelegt ist.It is also possible that the soft body between a shoulder of the hard body and a lock washer is fixed.

Insbesondere kann 1 vorgesehen sein, dass der Querschnitt der Lagerungswelle etwa elliptisch mit der Hauptachse in Auszugsrichtung ausgebildet ist.In particular, 1 may be provided that the cross section of the bearing shaft is formed approximately elliptical with the main axis in the extension direction.

Die Erfindung schlägt vor, die Welle an einer Halterung anzuordnen, insbesondere einstückig mit dieser auszubilden, die mit der Mittelschiene durch einfache Möglichkeiten verbunden werden kann, beispielsweise durch Einschnappen und/oder Einrasten.The invention proposes to arrange the shaft on a holder, in particular in one piece with this, which can be connected to the center rail by simple means, for example by snapping and / or snapping.

Auch die Steuerrolle kann, gleichgültig ob als Zweikomponentenbauteil oder aus zwei Bauteilen bestehend, auf der Welle durch einfaches Aufstecken und gegebenenfalls Schnappen oder durch eine geringfügige Verformung festgelegt werden.Also, the control roller, whether as a two-component component or consisting of two components, are fixed on the shaft by simply plugging and snapping if necessary or by a slight deformation.

Weitere Merkmale, Einzelheiten und Vorzüge der Erfindung ergeben sich aus den Patentansprüchen, deren Wortlaut durch Bezugnahme ebenso wie der Wortlaut der Zusammenfassung zum Inhalt der Beschreibung macht wird, der folgenden Beschreibung bevorzugter Ausführungsformen der Erfindung sowie anhand der Zeichnung. Hierbei zeigen:

Further features, details and advantages of the invention will become apparent from the claims, the wording of which is incorporated by reference as well as the wording of the abstract, the following description of preferred embodiments of the invention and with reference to the drawing. Hereby show:

Figur 1 zeigt zunächst in einer Stirnansicht, wie die Auszugsführung ausgebildet ist. Mit Hilfe eines oder mehrerer Winkelelemente 1 wird an der Innenseite des Korpus die Korpusschiene oder Tragschiene 2 angebracht. Gegenüber der Korpusschiene 2 ist mit Hilfe von Rollen 4 die Mittelschiene 3 verschiebbar. Gegenüber der Mittelschiene 3 ist wiederum, mit Hilfe von Rollen 4, die Auszugsschiene 5 verschiebbar gelagert. Mit der Auszugsschiene 5 wird dann die Schublade verbunden, beispielsweise durch Auflegen oder auch durch Festschrauben. Beim Herausziehen der Schublade wird also die Auszugsschiene 5 mit der Schublade mit verschoben, was zu einer Mitnahme der Mittelschiene 3 führt. Beim Abrollen der Rollen 4 zwischen der Auszugsschiene 5 und der Mittelschiene 3 wird die Mittelschiene 3 mit etwa der halben Geschwindigkeit bewegt. Durch Auftreten von Schlupf kann sich Position der Mittelschiene aber etwas ändern. Daher wird zur Erleichterung der Verschiebebewegung eine Synchronisierung der Bewegung der Mittelschiene mit der Auszugs- und Einschiebebewegung der Schublade gewünscht. Zu diesem Zweck enthält die Mittelschiene 3 eine Steuerrolle 6, die mit einem Flansch 7 der Auszugsschiene 5 und einem Flansch 8 der Korpusschiene 2 in Reibeingriff steht. FIG. 1 shows first in an end view of how the pullout guide is formed. With the help of one or more angle elements 1, the carcass rail or support rail 2 is attached to the inside of the body. Compared with the carcass rail 2, the middle rail 3 is displaceable by means of rollers 4. In contrast to the middle rail 3, in turn, with the help of rollers 4, the pull-out rail 5 is mounted displaceably. With the drawer rail 5, the drawer is then connected, for example by hanging or by tightening. When pulling out the drawer so the drawer rail 5 is moved with the drawer, which leads to entrainment of the center rail 3. When rolling the rollers 4 between the pull-out rail 5 and the center rail 3, the center rail 3 is moved at about half the speed. However, slip may cause the position of the center rail to change slightly. Therefore, in order to facilitate the sliding movement, it is desired to synchronize the movement of the center rail with the extension and insertion movement of the drawer. For this purpose, the center rail 3 includes a control roller 6 which is in frictional engagement with a flange 7 of the pull-out rail 5 and a flange 8 of the carcass rail 2.

Während die Rollen 4 zwischen den Schienen die Last der Schublade tragen, dient die Steuerrolle 6 der Synchronisierung der Bewegung der Mittelschiene beim Herausziehen und Einschieben der Schublade.While the rollers 4 between the rails carry the load of the drawer, the control roller 6 is used to synchronize the movement of the center rail when pulling out and pushing in the drawer.

Nun zu Figur 3. In Figur 3 ist ein Schnitt durch die Lagerung der Steuerrolle 6 dargestellt, wobei die Schnittebene in Auszugsrichtung verläuft, in Figur 1 und 2 also horizontal. Zur Befestigung der Steuerrolle 6 dient eine Lagerplatte 10, die mit Hilfe von Rastansätzen 11 mit der Mittelschiene 3 verbunden wird. Die Rastansätze 11, die an ihren freien Enden nach außen gerichtete Rastnasen aufweisen, werden unter einer gewissen Verformung durch entsprechende Durchbrüche 12 der Mittelschiene 3 hindurch gesteckt und federn dann nach außen.now to FIG. 3 , In FIG. 3 a section through the bearing of the control roller 6 is shown, wherein the cutting plane extends in the extension direction, in FIGS. 1 and 2 so horizontal. For fixing the control roller 6 is a bearing plate 10 which is connected by means of locking lugs 11 with the middle rail 3. The locking lugs 11, which have at their free ends outwardly directed latching lugs, are inserted through a certain deformation through corresponding openings 12 of the center rail 3 through and then spring outward.

An der der Mittelschiene 3 abgewandten Vorderseite enthält die Lagerplatte 10 einstückig angeformt die Welle 13 zur Lagerung der Steuerrolle 6. Bei dem Ausführungsbeispiel der Figur 3 ist das vordere, das heißt freie Ende der Welle 13 mit einem Einschnitt 14 versehen, so dass sich zwei nach innen spreizbare vordere Enden 15 ergeben. Beide vorderen Enden 15 weisen eine nach hinten, das heißt in Richtung auf die Mittelschiene 3 gerichtete Anlageschulter 16 auf.At the middle of the rail 3 facing away from the front bearing plate 10 integrally formed integrally with the shaft 13 for supporting the control roller 6. In the embodiment of the FIG. 3 is the front, that is free end of the shaft 13 is provided with an incision 14, so that there are two inwardly spreadable front ends 15. Both front ends 15 have a rearward, that is directed in the direction of the center rail 3 contact shoulder 16.

Auf die Welle 13 lässt sich, wenn die vorderen Enden 15 nach innen verformt sind, die Steuerrolle 6 aufschieben. Sie wird durch die Anlageschulter 16 dann festgelegt. Die Steuerrolle 16 weist einen Hartkörper 17 mit einer zylindrischen Außenfläche auf, der im vorderen Bereich eine gewisse Abschrägung 18 enthält. Im Bereich des gegenüberliegenden Stirnendes enthält der Hartkörper 17 einen Einstich, der eine parallel zur Vorderseite der Lagerplatte 10 verlaufende Anlageschulter 19 aufweist. In dem dadurch gebildeten Raum zwischen der Anlageschulter 19 und der Lagerplatte 10 ist ein umlaufender Ring 20 eingesetzt, der im dargestellten Beispiel die Form eines A-Rings aufweist. Die radiale Außenseite dieses Rings 20 steht etwas über die zylindrische Außenseite 21 des Hartkörpers 17 vor. Beim Einschieben zwischen die beiden Flansche 7, 8 liegt also zunächst die Außenseite des Rings 20 an den Flaschen 7, 8 an.On the shaft 13, when the front ends 15 are deformed inwardly, the control roller 6 can be postponed. It is then determined by the contact shoulder 16. The control roller 16 has a hard body 17 with a cylindrical outer surface, which contains a certain bevel 18 in the front region. In the region of the opposite front end of the hard body 17 includes a recess, which has a parallel to the front of the bearing plate 10 extending abutment shoulder 19. In the space thus formed between the contact shoulder 19 and the bearing plate 10, a circumferential ring 20 is inserted, which has the shape of an A-ring in the example shown. The radial outer side of this ring 20 projects slightly beyond the cylindrical outer side 21 of the hard body 17. When inserting between the two flanges 7, 8 is thus initially the outside of the ring 20 to the bottles 7, 8 at.

Bei der in Figur 3 dargestellten Ausführungsform ist der Ring 20 ein getrenntes Bauteil, das sich, bevor der Hartkörper 17 auf die Welle 13 aufgeschoben wird, mit dem Hartkörper verbinden lässt. Es ist aber auch möglich und liegt im Rahmen der Erfindung, dass die Baueinheit aus Hartkörper 17 und Ring 20 aus weicherem Material in Zweikomponentenbauweise hergestellt wird.At the in FIG. 3 illustrated embodiment, the ring 20 is a separate component that can be connected to the hard body before the hard body 17 is pushed onto the shaft 13. But it is also possible and is within the scope of the invention that the assembly of hard body 17 and ring 20 is made of softer material in two-component construction.

Der Hartkörper 17 kann beispielsweise aus Metall und der Ring 20 aus Kunststoff bestehen. Es ist aber auch möglich, dass der Hartkörper 17 aus einem härteren und der Ring 20 dann aus einem weicheren Kunststoff besteht.The hard body 17 may for example consist of metal and the ring 20 made of plastic. But it is also possible that the hard body 17 is made of a harder and the ring 20 then made of a softer plastic.

Figur 4 zeigt eine zweite Ausführungsform, bei der die gleiche Steuerrolle 6 in umgekehrter Orientierung verwendet wird. Die Abschrägung 18 liegt jetzt an der Vorderseite der leicht abgeänderten Halteplatte 30 an. Der Einstich mit der Schulter 19 ist demgegenüber an der entgegengesetzten Stirnseite angeordnet. Die Welle 23 weist keinen vorderen Einschnitt 14 auf, sondern verläuft massiv bis zur Vorderseite und hat dort einen im Durchmesser verringerten Ansatz 24. Nach dem Aufsetzen des Hartkörpers 17 und des Rings 20 wird dann auf das vordere Ende der Welle 23, genauer gesagt auf den Abschnitt 24 mit verringertem Durchmesser, eine Sicherungsscheibe 25 aufgesetzt und dort durch Verformung des äußeren Endes 24 gesichert. Der Ring 20, bei dem es sich um den gleichen Ring bei wie bei der Ausführungsform nach Figur 3 handeln kann, steht also wiederum in radialer Richtung etwas über die ansonsten zylindrische Oberfläche 21 des Hartkörpers 17 vor. FIG. 4 shows a second embodiment, in which the same control roller 6 is used in the reverse orientation. The bevel 18 is now at the front of the slightly modified retaining plate 30 at. The puncture with the shoulder 19 is arranged opposite to the opposite end side. The shaft 23 has no front notch 14, but extends solidly to the front and there has a reduced diameter lug 24. After placing the hard body 17 and the ring 20 is then on the front end of the shaft 23, more precisely on the Section 24 reduced diameter, a lock washer 25 is placed and secured there by deformation of the outer end 24. The ring 20, which is the same ring as in the embodiment according to FIG. 3 can act, so in turn in the radial direction something about the otherwise cylindrical surface 21 of the hard body 17 before.

Die Befestigung der Halterung 30 an der Mittelschiene 3 geschieht durch Ansätze, die in Öffnungen eingesetzt werden. Von der Rückseite her wird durch einen leichten Hammerschlag eine Vernietung der Halterung 30 an der Mittelschiene 3 hergestellt.The attachment of the bracket 30 to the center rail 3 is done by approaches that are used in openings. From the back a riveting of the holder 30 is made to the center rail 3 by a slight hammer blow.

Figur 5 zeigt nun in vergrößertem Maßstab einen Ausschnitt aus der Figur 2. Die Lagerplatte 30 verläuft in ihrer Längsrichtung in Auszugsrichtung. Der Querschnitt der Welle 23 ist elliptisch. Die Hauptachse der Ellipse 23 verläuft in Auszugsrichtung, das heißt in Figur 5 von links nach rechts. In dazu senkrechter Richtung verläuft die Nebenachse der Ellipse, die also deutlich kleiner ist. Die Steuerrolle 6 wird in Auszugsrichtung und Einschieberichtung exakt geführt, hat aber in dazu senkrecht verlaufender Richtung ein gewisses bewusstes Spiel, das natürlich kleiner ist als die Differenz zwischen der Innenöffnung der Steuerrolle und der kleinen Achse der Ellipse der Welle 23. FIG. 5 shows now on an enlarged scale a section of the FIG. 2 , The bearing plate 30 extends in the longitudinal direction in the extension direction. The cross section of the shaft 23 is elliptical. The main axis of the ellipse 23 extends in the extension direction, that is in FIG. 5 left to right. In the direction perpendicular to the minor axis of the ellipse, which is so much smaller. The control roller 6 is accurately guided in the extension direction and insertion direction, but has in this direction perpendicular to a certain conscious game, which of course is smaller than the difference between the inner opening of the control roller and the minor axis of the ellipse of the shaft 23rd
