Description

Die vorliegende Erfindung bezieht sich auf eine Schubladenausziehführungschiene mit einer Vorrichtung zur Anbringung eines Funktionsteiles an einer Schiene einer Schubladenausziehführung, mit einem ersten Lagerelement und mit zumindest einem zweiten Lagerelement, wobei die Lagerelemente zum einen im vorderen Endbereich der Schiene und zum anderen im hinteren Endbereich der Schiene anzuordnen sind.The present invention relates to a drawer pull-out guide rail with a device for attaching a functional part to a rail of a drawer pull-out guide, with a first bearing element and with at least one second bearing element, wherein the bearing elements on the one hand in the front end of the rail and the other in the rear end of the rail are to be arranged.

Im Weiteren betrifft die Erfindung eine Schubladenausziehführung, wobei ein Funktionsteil - insbesondere eine Zahnstange, eine Einzugsvorrichtung für Schubladen, eine Touch-Latch-Vorrichtung und/oder eine Dämpfvorrichtung zur Dämpfung einer Schienenbewegung - über eine Schubladenausziehführungschiene der zu beschreibenden Art an einer Schiene der Schubladenausziehführung befestigt ist.Furthermore, the invention relates to a drawer pull-out guide, wherein a functional part - in particular a rack, a draw-in device for drawers, a touch-latch device and / or a damping device for damping a rail movement - attached via a drawer extension guide rail of the type to be described on a rail of the drawer extension is.

Die Anbringung von Funktionsteilen an einer Schubladenausziehführung ist beispielsweise in der DE 20 2008 012 996 U1 beschrieben. Bei diesem Dokument sind die Funktionsteile als Endstopfen ausgeführt, welche am vorderen und am hinteren Endbereich der Laufschiene, insbesondere auch kraftschlüssig, angeordnet werden. Die Funktionsteile können hierbei unter anderem zur Kopplung oder Sicherung der Schublade, als Endanschläge sowie als Verriegelung der Schließstellung ausgeführt sein. Die an den beiden Endbereichen der Laufschiene anzuordnenden Endstopfen können sich insbesondere bei hoher Krafteinwirkung von der Schiene ablösen, insbesondere dann, wenn über die Funktionsteile eine Kraft zur Schienenbewegung der Ausziehführung übertragen wird.The attachment of functional parts to a drawer extension guide is for example in the DE 20 2008 012 996 U1 described. In this document, the functional parts are designed as end plugs, which are arranged at the front and at the rear end region of the running rail, in particular also non-positively. The functional parts can be designed, inter alia, for coupling or securing the drawer, as end stops and as a locking of the closed position. The end plugs to be arranged at the two end regions of the running rail can become detached from the rail, in particular when there is a high force, in particular when a force for rail movement of the pull-out guide is transmitted via the functional parts.

Die Anbringung von Funktionsteilen an einer Schubladenausziehführung ist auch in der US 7,077,488 B2 , in der DE 20 2008 008 121 U1 , in der EP 2 168 455 A1 sowie in der DE 202 04 724 U1 beschrieben. Auch bei diesen Konstruktionen besteht die erhebliche Gefahr, dass sich die Funktionsteile bei Krafteinwirkung leicht von der Schiene der Schubladenausziehführung ablösen können.The attachment of functional parts to a drawer extension is also in the US 7,077,488 B2 , in the DE 20 2008 008 121 U1 , in the EP 2 168 455 A1 as well as in the DE 202 04 724 U1 described. Even with these constructions, there is the considerable risk that the functional parts can easily detach from the rail of the drawer extension guide upon application of force.

Aufgabe der vorliegenden Erfindung ist es daher, eine Schubladenausziehführungschiene der eingangs erwähnten Gattung vorzuschlagen, wobei ein Funktionsteil der Schubladenausziehführung in rascher, komfortabler und zuverlässiger Weise an einer Schiene der Schubladenausziehführung befestigt werden kann.Object of the present invention is therefore to propose a drawer extension guide rail of the type mentioned, wherein a functional part of Drawer pull-out guide can be fastened in a rapid, comfortable and reliable manner to a rail of the drawer pull-out guide.

Dies wird erfindungsgemäß durch die Merkmale des Patentanspruchs 1 gelöst. Weitere vorteilhafte Ausgestaltungen der Erfindung sind in den abhängigen Unteransprüchen angegeben.This is achieved by the features of claim 1. Further advantageous embodiments of the invention are specified in the dependent subclaims.

Gemäß der Erfindung ist also vorgesehen, dass wenigstens eine Spannvorrichtung vorgesehen ist, durch welche die wenigstens zwei Lagerelemente in deren Montagelage an der Schiene miteinander verbindbar und relativ zueinander verspannbar sind.According to the invention, it is thus provided that at least one tensioning device is provided, by means of which the at least two bearing elements can be connected to one another in the mounting position on the rail and can be braced relative to one another.

Auf diese Weise können zunächst die beiden Lagerelemente kräftefrei an der Schiene der Schubladenausziehführung vorpositioniert werden, ohne dass dabei eine kraftschlüssige Verbindung diese Vormontage erschwert. Nach erfolgter Positionierung der beiden Lagerteile an der Schiene können diese durch die Spannvorrichtung miteinander verbunden und in Montagelage relativ zueinander verspannt werden. Auf diese Weise kann eine komfortable und rasche Befestigung der Lagerteile an den Schienen herbeigeführt werden, wobei die Lagerteile auch gegen ein ungewolltes Ablösen von der Schiene ausreichend gesichert sind.In this way, first of all the two bearing elements can be prepositioned without force on the rail of the drawer extension guide, without any frictional connection making this pre-assembly more difficult. After the positioning of the two bearing parts on the rail, these can be interconnected by the clamping device and clamped in the mounting position relative to each other. In this way, a comfortable and rapid attachment of the bearing parts can be brought to the rails, the bearing parts are sufficiently secured against unwanted detachment from the rail.

Gemäß einem Ausführungsbeispiel kann vorgesehen sein, dass die Spannvorrichtung wenigstens ein Spannband - vorzugsweise aus einem flexiblen Kunststoffmaterial - umfasst, durch welches die beiden Lagerelemente miteinander verbindbar und relativ zueinander verspannbar sind. Das Spannband kann als Rastband - insbesondere als Kabelbinder - ausgeführt sein, wobei durch das Spannband die beiden Lagerelemente in deren Montagelage an der Schiene festgezurrt werden können. Durch Ziehen des - vorzugsweise selbstverrastenden - Rastbandes ist dieses relativ zu wenigstens einem der beiden Lagerteile stufenweise verrastbar, wobei durch Spannen des Spannbandes die beiden Lagerelemente an den Schienen klemmend fixierbar sind. Die Lagerelemente können zudem auch eine formschlüssige Befestigungsmöglichkeit zur Verbindung mit der Schiene aufweisen. Die beiden Lagerelemente können daher als Formteile ausgeführt sein, welche zur Vorpositionierung jeweils auf ein stirnseitiges Ende der Schiene aufschiebbar sind, woraufhin die Lagerelemente nach erfolgter Positionierung durch die Spannvorrichtung relativ zueinander verspannbar sind.According to one exemplary embodiment, it can be provided that the tensioning device comprises at least one tensioning band-preferably made of a flexible plastic material-by means of which the two bearing elements can be connected to one another and braced relative to one another. The strap can be designed as a locking strap - in particular as a cable tie -, which can be lashed by the tension band, the two bearing elements in their mounting position on the rail. By pulling the - preferably selbstverrastenden - locking band this is gradually locked relative to at least one of the two bearing parts, by clamping the tension band, the two bearing elements are clamped to the rails. The bearing elements may also have a positive attachment for connection to the rail. The two bearing elements can therefore be designed as molded parts, which can be pushed onto a frontal end of the rail for pre-positioning, whereupon the bearing elements can be braced relative to each other after positioning by the tensioning device.

Die so befestigten Lagerteile eignen sich insbesondere zur - auch nachträglichen - Montage eines Funktionsteiles, beispielsweise von Synchronisierungsmitteln zur Synchronisierung einer Schienenbewegung zweier gesonderter Schubladenausziehführungen, welche im Montagezustand an einem Möbelkorpus an gegenüberliegenden Seitenwänden befestigt sind. Gemäß einem möglichen Ausführungsbeispiel der Erfindung kann vorgesehen sein, dass das Funktionsteil eine Zahnstange aufweist, welche mit den beiden Lagerelementen verbunden oder lösbar verbindbar ist. Zur lösbaren Verbindung des Funktionsteiles mit zumindest einem der beiden Lagerteile kann eine lösbare Befestigungseinrichtung - insbesondere eine Schnappverbindung - vorgesehen werden.The so-mounted bearing parts are particularly suitable for - even retrofitting - a functional part, for example, synchronizing means for synchronizing a rail movement of two separate Schubladenausziehführungen, which are fixed in the assembled state to a furniture body on opposite side walls. According to a possible embodiment of the invention it can be provided that the functional part has a toothed rack, which is connected to the two bearing elements or detachably connectable. For releasable connection of the functional part with at least one of the two bearing parts, a releasable fastening device - in particular a snap connection - are provided.

Durch die stabile Anordnung der Lagerelemente relativ zur Schiene eignet sich das Funktionsteil zur Aufnahme relativ großer Kräfte. Über die Zahnstange ist es beispielsweise möglich, dass eine Bewegung einer ersten Schubladenausziehführung mit einer Bewegung einer zweiten - gesonderten - Schubladenausziehführung synchronisierbar ist. Die Schienenbewegung der ersten Schubladenausziehführung kann daher über ein mit der Zahnstange kämmendes Zahnrad und über eine Torsionswelle mit der Schienenbewegung der zweiten Schubladenausziehführung synchronisiert werden.Due to the stable arrangement of the bearing elements relative to the rail, the functional part for receiving relatively large forces. It is possible, for example, via the toothed rack, that a movement of a first drawer extension guide can be synchronized with a movement of a second, separate drawer extension guide. The rail movement of the first drawer extension guide can therefore be synchronized via a meshing with the rack gear and a torsion with the rail movement of the second drawer extension guide.

Gemäß einem Ausführungsbeispiel kann vorgesehen sein, dass das Funktionsteil eine Ausstoßvorrichtung zum Ausstoßen einer Schiene der Schubladenausziehführung aus einer geschlossenen Endlage in eine Offenstellung aufweist. Solche Ausstoßvorrichtungen sind als Touch-Latch-Vorrichtungen bekannt geworden, wobei durch manuelle Druck- und/oder Zugausübung auf die Schublade ein Ausstoßen derselben aus einer geschlossenen Endlage herbeigeführt werden kann.According to one embodiment, it can be provided that the functional part has an ejection device for ejecting a rail of the drawer extension guide from a closed end position into an open position. Such ejection devices have become known as touch-latch devices, which can be caused by manual pressure and / or pulling exercise on the drawer ejecting the same from a closed end position.

Alternativ oder ergänzend kann vorgesehen sein, dass das Funktionsteil eine Einzugsvorrichtung aufweist, durch die eine bewegbare Schiene der Schubladenausziehführung gegen Ende der Schließbewegung in die vollständige Schließstellung ziehbar ist. Solche federunterstützten Selbsteinzugsvorrichtungen sind in vielen Ausgestaltungen bereits bekannt geworden, wobei die Schublade über einen federbeaufschlagten Mitnehmer in die geschlossene Endlage ziehbar ist.Alternatively or additionally, it can be provided that the functional part has a collection device, by means of which a movable rail of the drawer extension guide can be pulled towards the end of the closing movement into the complete closed position. Such spring-assisted self-closing devices are already known in many embodiments, the drawer can be pulled over a spring-loaded driver in the closed end position.

Im Weiteren kann das Funktionsteil eine Dämpfvorrichtung, insbesondere einen als Rotationsdämpfer oder einen als Lineardämpfer ausgebildeten Fluiddämpfer - aufweisen, wobei durch die Dämpfvorrichtung eine Bewegung der Schublade über den letzten Schließweg bis hin zur vollständigen Schließstellung dämpfbar ist.Furthermore, the functional part can have a damping device, in particular a fluid damper designed as a rotary damper or a linear damper, wherein a movement of the drawer over the last closing path up to the complete closed position can be damped by the damping device.

Die erfindungsgemäße Schubladenausziehführung weist eine an einem Möbelkorpus zu befestigende Korpusschiene und wenigstens eine relativ dazu bewegbar gelagerte Ladenschiene auf, wobei zumindest ein Funktionsteil über eine Schubladenausziehführungschiene der beschriebenen Art mit der Korpusschiene oder mit der Ladenschiene verbunden ist.The drawer extension guide according to the invention has a cabinet rail to be fastened to a furniture carcass and at least one drawer rail mounted movably relative to it, at least one functional part being connected to the carcass rail or to the drawer rail via a drawer pull-out guide rail of the type described.
