Description

Teleskopauszug telescopic extension
Die vorliegende Erfindung betrifft einen Teleskopauszug mit wenigstens einem Schienenpaar, das eine eine Nut begrenzende äußere Schiene und eine in der Nut der äußeren Schiene geführte und in Bezug zu dieser längs verschiebbare innere Schiene umfasst. Derartige Teleskopauszüge werden zum Beispiel eingesetzt, um in Haushaltgeräten mit einem Innenraum ein Einbauteil in dem Innenraum beweglich zu führen. Ein solcher Teleskopauszug wird zum Beispiel eingesetzt für die bewegliche HaI- terung eines Auszugkastens in einem Kühl- oder Gefrierschrank, eines Geschirrkorbes in einer Spülmaschine oder eines Backbleches oder Rostes in einem Backofen.The present invention relates to a telescopic extension with at least one pair of rails, which comprises a groove bounding an outer rail and guided in the groove of the outer rail and with respect to this longitudinally displaceable inner rail. Such telescopic extensions are used, for example, to move in household appliances with an interior a built-in part in the interior movable. Such a telescopic extension is used, for example, for the movable mounting of an extension box in a refrigerator or freezer, a dish rack in a dishwasher or a baking tray or grid in an oven.
Im Allgemeinen liegt bei einem solchen Teleskopauszug zwischen einem eine Seitenwand der Nut bildenden Bereich der äußeren Schiene und der inneren Schiene ein Spalt offen. Zwischen den sich gegeneinander bewegenden Schienen kann sich Abrieb bilden, der aus diesem Spalt herausfallen kann, oder es können zwischen den Schienen eingebrachte Schmierstoffe austreten, was insbesondere bei einem Haushaltgerät, in dem sich Lebensmittel befinden können, wie etwa einem Kältegerät oder einem Backofen, unerwünscht ist. Ferner besteht die Möglichkeit, dass Schmutz oder Lebensmittelreste zwischen die Schienen gelangen, zwischen diesen abgebaut werden und Überreste wieder durch den Spalt herausfallen, was ebenfalls für einen Benutzer störend ist.In general, in such a telescopic extension between a side wall of the groove forming portion of the outer rail and the inner rail, a gap is open. Abrasion may form between the mutually moving rails, which may fall out of this gap, or lubricants introduced between the rails may leak, which is undesirable in particular in a domestic appliance in which food may be present, such as a refrigerator or an oven is. Furthermore, there is the possibility that dirt or food residues get between the rails, are broken down between them and remains fall out through the gap again, which is also disturbing for a user.
Ziel der vorliegenden Erfindung ist, einen Teleskopauszug der eingangs angegebenen Art zu schaffen, bei dem ein unkontrollierter Austritt von Verunreinigungen mit geringem Aufwand verhindert werden kann.The aim of the present invention is to provide a telescopic extension of the type specified, in which an uncontrolled leakage of impurities can be prevented with little effort.
Die Aufgabe wird dadurch gelöst, dass mit einer der Schienen eine Rinne verbunden ist, die sich unterhalb des Spaltes erstreckt, um herausfallende Verunreinigungen aufzufangen.The object is achieved in that with one of the rails, a channel is connected, which extends below the gap to catch falling out impurities.
Um eine leichte Beweglichkeit der Schienen gegeneinander zu gewährleisten, sind in dem Spalt vorzugsweise Wälzkörper längsbeweglich angeordnet. Um eine große Bewegungsfreiheit des Teleskopauszuges zu erzielen, die vorzugsweise größer ist als die Länge seiner Schienen, ist vorzugsweise ein zweites Schienenpaar mit zwei in Bezug zueinander längs verschiebbaren Schienen vorgesehen, wobei eine der Schienen des ersten Schienenpaares mit einer der Schienen des zweiten Schienenpaares fest verbunden ist.In order to ensure a slight mobility of the rails against each other, rolling elements are preferably arranged longitudinally movable in the gap. In order to achieve a large freedom of movement of the telescopic extension, which is preferably greater than the length of its rails, a second pair of rails is preferably provided with two mutually longitudinally displaceable rails, wherein one of the rails of the first pair of rails with one of the rails of the second pair of rails firmly connected is.
Das zweite Schienenpaar kann im Wesentlichen genauso wie das erste aufgebaut sein, mit einer eine Nut begrenzenden äußeren und einer in die Nut eingreifenden, in Bezug zu der äußeren Schiene längs verschiebbaren inneren Schiene, zwischen denen ein Spalt offen liegt. Die Rinne erstreckt sich dann vorzugsweise unterhalb der Spalte beider Schienenpaare.The second pair of rails may be constructed substantially the same as the first, with an outer groove bounding a groove, and an inner rail longitudinally slidable relative to the outer rail and having a gap therebetween. The channel then preferably extends below the column of both pairs of rails.
Um einen Schutz vor herausfallenden Verunreinigungen auch im ausgestreckten Zustand des Teleskopauszuges zu gewährleisten, ist zweckmäßigerweise eine zweite Rinne vorgesehen, die mit der anderen Schiene des ersten Schienenpaares oder mit einer Schiene des zweiten Schienenpaares verbunden sein kann.In order to ensure protection against falling out impurities in the extended state of the telescopic extension, a second channel is expediently provided, which may be connected to the other rail of the first pair of rails or to a rail of the second pair of rails.
Bei einem Teleskopauszug mit zwei Schienenpaaren kann ferner ein eine Seitenwand der Nut bildender Bereich der äußeren Schiene des zweiten Schienenpaares sich bis unter das erste Schienenpaar erstrecken, um die Rinne zu bilden.Further, in a telescopic drawer with two pairs of rails, a portion of the outer rail of the second rail pair forming a side wall of the groove may extend below the first pair of rails to form the gutter.
Die Rinne kann zwischen einer der Schienen und einer Wand, an der diese Schiene befestigt ist, gehalten sein. In diesem Fall ist ein zwischen die eine Schiene und die Wand eingreifender Abschnitt der Rinne vorzugsweise elastisch stauchbar, um der Rinne trotz eventuell streuender Breite eines den Abschnitt aufnehmenden Zwischenraumes zwischen Schiene und Wand spielfreien Halt zu geben.The gutter may be held between one of the rails and a wall to which this rail is attached. In this case, a portion of the channel engaging between the rail and the wall is preferably elastically compressible in order to give the channel clearance-free support despite the possibly scattering width of a section-receiving gap between the rail and the wall.
Auf die äußere Schiene kann die Rinne auch aufgerastet sein.On the outer rail, the groove can also be snapped.
Gegenstand der Erfindung ist ferner ein schrankartiges Haushaltsgerät mit einem Innenraum, in dem ein Einbauteil über einen Teleskopauszug wie oben definiert beweglich geführt ist. Weitere Merkmale und Vorteile der Erfindung ergeben sich aus der nachfolgenden Beschreibung von Ausführungsbeispielen unter Bezugnahme auf die beigefügten Figuren. Es zeigen:The invention further relates to a cabinet-like household appliance with an interior in which a built-in part via a telescopic extension as defined above is movably guided.

Der in Fig. 1 gezeigte Teleskopauszug umfasst in an sich bekannter Weise zwei Schienenpaare 1 , 2 mit jeweils einer äußeren Schiene 3 bzw. 5 und einer inneren SchieneThe telescopic extension shown in Fig. 1 comprises in known manner two pairs of rails 1, 2, each with an outer rail 3 or 5 and an inner rail
4 bzw. 6, die in eine Längsnut der äußeren Schiene 3 bzw. 5 verschiebbar eingreift. Die Schienen 3, 4, 5, 6 sind jeweils aus Stahlblechstreifen geformt und haben eine im Wesentlichen ebene, in Einbaulage des Teleskopauszuges vertikal orientierte Boden- platte 7 sowie von der Bodenplatte 7 an deren oberem und unterem Rand abgewinkelte Schenkel 8, 9. Die einander zugewandten Seiten der Schenkel 8 der äußeren Schienen 3,4 and 6, which engages in a longitudinal groove of the outer rail 3 and 5 slidably. The rails 3, 4, 5, 6 are each formed from sheet-steel strips and have a substantially flat bottom plate 7, vertically oriented in the installed position of the telescopic extension, and legs 8, 9 angled away from the bottom plate 7 at their upper and lower edges facing sides of the legs 8 of the outer rails 3,
5 und der Schenkel 9 der inneren Schienen 4, 6 sind konkav, so dass die sich gegenüberliegenden Schenkel jeweils einen Führungskanal 10 bilden, in dem Kugeln 1 1 (siehe zum Beispiel Fig. 4) aufgenommen sind. Die Kugeln 1 1 vermitteln jeweils eine spiel- und reibungsarme Führung der Schienen eines Paares aneinander. Auf die äußere Schiene 3 des Schienenpaares 1 sind zwei Adapter 12, 13 aufgerastet. Abstehende Kopfstücke 14, 15 der Adapter 12, 13 dienen zur Befestigung eines in der Fig. 1 nicht gezeigten Einbauteiles wie etwa eines Auszugkastens für ein Kältegerät.5 and the legs 9 of the inner rails 4, 6 are concave, so that the opposite legs each form a guide channel 10, are received in the balls 1 1 (see, for example, Fig. 4). The balls 1 1 each provide a play and low-friction guidance of the rails of a pair together. On the outer rail 3 of the rail pair 1, two adapters 12, 13 are snapped. Projecting head pieces 14, 15 of the adapter 12, 13 are used for attachment of a built-in part, not shown in FIG. 1, such as a pull-out box for a refrigeration device.
Die innere Schiene 6 des Schienenpaares 2 ist zur Befestigung an einer Wand, insbesondere einer Innenwand eines Kältegerätes, vorgesehen. Zwischen dieserThe inner rail 6 of the rail pair 2 is provided for attachment to a wall, in particular an inner wall of a refrigeration device. Between this
Innenwand und der Schiene 4 ist ein Kunststoffprofil 16 mit einem L- oder J-förmigenInner wall and the rail 4 is a plastic profile 16 with an L or J-shaped
Querschnitt eingeklemmt. Dieses Profil 16 ist in Fig. 2 für sich allein dargestellt. In einem vertikalen Schenkel 17 des Profils 16 sind Öffnungen 18 gebrochen, durch die sich im montierten Zustand Befestigungsmittel der Schiene 4 oder der Wand erstrecken, welche die Bodenplatte 7 der Schiene 4 in einem definierten Abstand zu der Innenwand und parallel zu dieser fixieren. Die Wandstärke des Schenkels 17 und die Wölbung eines dieCross-section clamped. This profile 16 is shown in Fig. 2 by itself. In a vertical leg 17 of the profile 16 openings 18 are broken, extend in the mounted state fastening means of the rail 4 or the wall, which fix the bottom plate 7 of the rail 4 at a defined distance to the inner wall and parallel to this. The wall thickness of the leg 17 and the curvature of the
Öffnungen 18 enthaltenden, gegen die Schiene 6 vorspringenden Mittelabschnittes 19 des Schenkels 17 sind so bemessen, dass der Mittelabschnitt 19 im montierten Zustand, wie in Fig. 1 gezeigt, zwischen der Bodenplatte 7 der Schiene 4 und der Innenwand des Kältegerätes elastisch flachgedrückt ist. So ist eine hinreichend feste Halterung desOpenings containing 18, projecting against the rail 6 central portion 19 of the leg 17 are dimensioned so that the central portion 19 in the mounted state, as shown in Fig. 1, between the bottom plate 7 of the rail 4 and the inner wall of the refrigerator is flattened elastic. So is a sufficiently firm support of the
Profils 16 trotz eventueller Fertigungstoleranzen des Abstandes zwischen Bodenplatte 7 und Kältegeräte-Innenwand gewährleistet.Profile 16 guaranteed despite any manufacturing tolerances of the distance between the bottom plate 7 and the refrigerator interior wall.
Ein horizontaler Schenkel 20 des Profils 16 steht von der Kältegeräte-Innenwand ab und erstreckt sich unterhalb der Schienenpaare 1 , 2. Partikel, die aus den Führungskanälen 10 der Schienenpaare herausfallen, werden von dem horizontalen Schenkel 20 aufgefangen und können sich so nicht im Inneren des Kältegerätes verteilen.A horizontal leg 20 of the profile 16 protrudes from the refrigerator inner wall and extends below the pairs of rails 1, 2. Particles that fall out of the guide channels 10 of the rail pairs are caught by the horizontal leg 20 and so can not be inside the Distribute refrigeration appliance.
Fig. 3 zeigt eine zu Fig. 1 analoge perspektivische Ansicht eines Teleskopauszuges gemäß einer zweiten Ausgestaltung der Erfindung. Die Schienenpaare 1 , 2 sind identisch mit den in Fig. 1 gezeigten. Ein Kunststoffprofil 21 umfasst einen vertikalen Schenkel 22, an den zwei die Schenkel 8 der Schiene 3 umgreifende, elastische Klauen 23 angeformt sind. Ein horizontaler Schenkel 24 des Profils 21 erstreckt sich unterhalb derFIG. 3 shows a perspective view, similar to FIG. 1, of a telescopic extension according to a second embodiment of the invention. The rail pairs 1, 2 are identical to those shown in Fig. 1. A plastic profile 21 comprises a vertical leg 22, to which two legs 8 of the rail 3 embracing, elastic claws 23 are integrally formed. A horizontal leg 24 of the profile 21 extends below the
Führungskanäle 10. Auch dieser Schenkel 24 ist in der Lage, aus den Kanälen 10 herausfallende Partikel aufzufangen und deren unkontrollierte Ausbreitung zu verhindern.Guide channels 10. Also, this leg 24 is able to catch falling out of the channels 10 particles and prevent their uncontrolled spread.
Fig. 4 zeigt einen Schnitt durch den Teleskopauszug der Fig. 3, eingebaut in einem Kältegerät, entlang einer durch den Adapter 12 und das Kopfstück 14 verlaufenden Ebene. Ein bruchstückhaft dargestellter, aus durchbrochenem Blech geformter Auszugkasten 25 ist an einem quer zur Schnittebene langgestreckten Adapterstück 26 verschraubt, das seinerseits auf die Kopfstücke 14, 15 aufgerastet ist. Die einander zugewandten Bodenplatten 7 der Schienen 4, 5 sind durch Nieten 27 zusammengehalten, von denen eine zusammen mit einem an der Schiene 5 befestigten elastischen Puffer 28 als Wegbegrenzungsanschlag dient, der eine ungewollte Lösung der Schienen 4, 5 voneinander verhindert. Die Schiene 4 ist über ein Abstandsstück 29 an der Innenwand 30 des Kältegerätes verankert.Fig. 4 shows a section through the telescopic extension of FIG. 3, installed in a refrigerator, along a through the adapter 12 and the head 14 extending Level. A fragmentary illustrated, formed from openwork sheet drawer 25 is screwed to a transversely to the cutting plane elongated adapter piece 26, which in turn is latched onto the head pieces 14, 15. The mutually facing bottom plates 7 of the rails 4, 5 are held together by rivets 27, one of which together with an attached to the rail 5 elastic buffer 28 serves as Wegbegrenzungsanschlag, which prevents unwanted solution of the rails 4, 5 from each other. The rail 4 is anchored via a spacer 29 on the inner wall 30 of the refrigerator.
Das gemäß Fig. 1 zwischen Kältegeräte-Innenwand und Schiene 6 eingeklemmte Profil 16 ist ortsfest; es kann daher nicht das Herausfallen von Partikeln aus den Führungskanälen 10 von Abschnitten der Schienen verhindern, die aus dem Kältegerät herausgezogen sind. Umgekehrt bietet das bewegliche Profil 21 keine vollständige Absicherung mehr, wenn es mit der Schiene 3 aus dem Innenraum des Kältegerätes herausgezogen ist. Vorzugsweise werden daher beide Profile 16, 21 in Kombination miteinander eingesetzt, wie in Fig. 5 anhand eines Schnittes durch die Schienenpaare 1 , 2 dargestellt. Der horizontale Schenkel 24 des Profils 21 verläuft hier tiefer als der horizontale Schenkel 20 des Profils 16, so dass der gesamte Teleskopauszug an seiner von der Wand 30 abgewandten Seite eine weitgehend geschlossene, leicht zu reinigende Oberfläche hat.The clamped according to Figure 1 between refrigeration device inner wall and rail 6 profile 16 is stationary. therefore, it can not prevent particles from falling out of the guide channels 10 from portions of the rails pulled out of the refrigerator. Conversely, the movable profile 21 no longer provides full protection when it is pulled out with the rail 3 from the interior of the refrigerator. Preferably, therefore, both profiles 16, 21 used in combination with each other, as shown in Fig. 5 with reference to a section through the pairs of rails 1, 2. The horizontal leg 24 of the profile 21 extends here deeper than the horizontal leg 20 of the profile 16, so that the entire telescopic extension has on its side facing away from the wall 30 a largely closed, easy to clean surface.
Fig. 6 zeigt eine vierte Ausgestaltung eines erfindungsgemäßen Teleskopauszuges in einem Schnitt analog zu denjenigen der Figuren 4 und 5. Ein zwischen der inneren Schiene 6 und der Innenwand 30 des Kältegerätes eingeklemmtes Profil 16 hat wie das in Fig. 2 gezeigte einen vertikalen Schenkel 17 und einen horizontalen Schenkel 20, wobei allerdings die Breite des Schenkels 20 in der Ausgestaltung der Fig. 6 reduziert ist, so dass sich dieser nur bis unter das der Wand 30 benachbarte Schienenpaar 2 erstreckt. Der untere horizontale Schenkel 8 der Schiene 3 des von der Wand 30 abgewandten Schienenpaars 1 ist durch einen sich rinnenförmig unterhalb des Schienenpaares 2 erstreckenden Abschnitt 31 verbreitert, der aus den Führungskanälen 10 beider Schienenpaare 1 , 2 austretende Partikel auffangen kann. Der rinnenförmige Abschnitt 31 greift zwischen das Schienenpaar 2 und den horizontalen Schenkel 20 des Profils 16 ein. Im ausgefahrenen Zustand des Teleskopauszuges ist der rinnenförmige Abschnitt 31 auf dem überwiegenden Teil seiner Länge aus dem Zwischenraum zwischen Schienenpaar 1 und Schenkel 20 herausgerückt, so dass dieser Zwischenraum zugänglich ist und gereinigt werden kann. Gleichzeitig liegt die Oberseite des aus dem Kältegerät herausgezogenen rinnenförmigen Abschnittes 31 frei und kann ebenfalls leicht gereinigt werden. Fig. 6 shows a fourth embodiment of a telescopic extension according to the invention in a section analogous to those of Figures 4 and 5. A pinched between the inner rail 6 and the inner wall 30 of the refrigerator profile 16 has as shown in Fig. 2, a vertical leg 17 and a horizontal leg 20, wherein, however, the width of the leg 20 is reduced in the embodiment of FIG. 6, so that this extends only below the wall 30 adjacent rail pair 2. The lower horizontal leg 8 of the rail 3 of the remote from the wall 30 pair of rails 1 is widened by a groove-shaped below the rail pair 2 extending portion 31, which can collect from the guide channels 10 of both pairs of rails 1, 2 exiting particles. The channel-shaped section 31 engages between the pair of rails 2 and the horizontal legs 20 of the profile 16. In the extended state of the telescopic extension of the channel-shaped portion 31 is on the majority of its length from the space between the pair of rails. 1 and legs 20 pulled out so that this space is accessible and can be cleaned. At the same time, the top side of the trough-shaped section 31 pulled out of the refrigeration device is exposed and can likewise be easily cleaned.
