Description
Die vorliegende Erfindung bezieht sich auf eine Ladenschiene für eine Schubladenausziehführung, mit:
- einer an einer Schublade zu befestigenden oder befestigten ersten Schiene,
- einer an einer Korpusschiene oder Mittelschiene einer Schubladenausziehführung anzuordnenden oder angeordneten zweiten Schiene,
- wobei die erste Schiene und die zweite Schiene durch Aufschieben miteinander verbindbar sind, wobei an der ersten oder zweiten Schiene zumindest ein Federmittel angeordnet ist.
- a first rail to be fastened or fastened to a drawer,
- a second rail to be arranged or arranged on a carcass rail or middle rail of a drawer extension runner,
- wherein the first rail and the second rail can be connected to one another by sliding them on, wherein at least one spring means is arranged on the first or second rail.
Im Weiteren betrifft die Erfindung eine Schubladenausziehführung mit zumindest einer Ladenschiene der zu beschreibenden Art sowie ein Möbel mit einem Möbelkorpus und einer relativ zum Möbelkorpus verfahrbar gelagerten Schublade, wobei die erste Schiene an der Schublade und die zweite Schiene am Möbelkorpus vormontiert sind, wobei die mit der Schublade verbundene erste Schiene durch Aufschieben auf die zweite Schiene mit der zweiten Schiene verbindbar ist.Furthermore, the invention relates to a drawer extension slide with at least one drawer rail of the type to be described and a piece of furniture with a furniture body and a drawer mounted so as to be movable relative to the furniture body, the first rail being preassembled on the drawer and the second rail being preassembled on the furniture body Drawer connected first rail can be connected to the second rail by sliding onto the second rail.
Bei der erstmaligen Montage einer Schublade an einer Schubladenausziehführung werden üblicherweise eine erste Schiene an der Schublade sowie eine Schubladenausziehführung mit einer zweiten Schiene am Möbelkorpus vormontiert. Im Anschluss daran wird die Schublade mit der ersten Schiene auf die zweite Schiene der Schubladenausziehführung aufgeschoben, bis eine selbsttätige Verriegelung zwischen der ersten Schiene und der zweiten Schiene erfolgt. Im Normalbetrieb sind die erste und die zweite Schiene relativ zueinander unverschiebbar angeordnet und bilden quasi eine zweiteilige Ladenschiene der Schubladenausziehführung aus. Durch ein an der ersten oder zweiten Schiene angeordnetes Federmittel, welches an der anderen Schiene abstützbar ist, kann im montierten Zustand der Schienen ein seitlich zur Längsrichtung der Schienen auftretendes Spiel zwischen der ersten und zweiten Schiene kompensiert werden. Das Federmittel kann beispielsweise als verbiegbare Federlasche oder Federzunge ausgebildet sein, welche aus dem Material einer Schiene ausgestanzt ist und durch welche das vorhandene Spiel zwischen der ersten und zweiten Schiene ausgleichbar ist. Je nach der Größe des vorhandenen Spiels zwischen der ersten und zweiten Schiene ist die Federlasche oder Federzunge relativ groß zu dimensionieren, wodurch neben einer unschönen Ausbildung auch die Gefahr einer Beschädigung des Federmittels, beispielsweise durch Abscheren, besteht.When a drawer is mounted on a drawer extension guide for the first time, a first rail on the drawer and a drawer extension guide with a second rail on the furniture body are usually preassembled. Subsequently, the drawer with the first rail is pushed onto the second rail of the drawer extension slide until an automatic locking occurs between the first rail and the second rail. In normal operation, the first and the second rails are arranged so as to be immovable relative to one another and form, as it were, a two-part drawer rail of the pull-out drawer. By a spring means arranged on the first or second rail, which spring means on the other rail can be supported, a play occurring laterally to the longitudinal direction of the rails between the first and second rails can be compensated for in the assembled state of the rails. The spring means can for example be designed as a bendable spring tab or spring tongue which is punched out of the material of a rail and by means of which the existing play between the first and second rails can be compensated. Depending on the size of the existing play between the first and second rails, the spring tab or spring tongue must be dimensioned relatively large, which means that, in addition to an unsightly design, there is also the risk of damage to the spring means, for example by shearing off.
In der
Aufgabe der vorliegenden Erfindung ist es, eine Ladenschiene der eingangs erwähnten Gattung unter Vermeidung der oben diskutierten Nachteile anzugeben.The object of the present invention is to provide a drawer rail of the type mentioned at the beginning while avoiding the disadvantages discussed above.
Dies wird erfindungsgemäß durch die Merkmale des Patentanspruchs 1 gelöst. Weitere vorteilhafte Ausführungen der Erfindung sind in den abhängigen Ansprüchen definiert.This is achieved according to the invention by the features of
Gemäß der Erfindung ist vorgesehen, dass an der anderen Schiene wenigstens ein Vorsprung angeordnet ist, dessen Lage an und/oder dessen Erstreckung entlang der anderen Schiene so gewählt ist, dass der wenigstens eine Vorsprung im verbundenen Zustand der ersten und zweiten Schiene zur Begrenzung von Querbewegungen der zwei Schienen zueinander mit dem Federmittel zusammenwirkt.According to the invention it is provided that at least one projection is arranged on the other rail, the position of which on and / or its extension along the other rail is selected so that the at least one projection in the connected state of the first and second rails to limit transverse movements the two rails interacts with one another with the spring means.
Mit anderen Worten liegt im verbundenen Zustand der beiden Schienen das Federmittel einer Schiene am Vorsprung der anderen Schiene an, sodass das Federmittel mit einer reduzierten, beispielsweise etwa der halben, Bauhöhe an einer Schiene ausgebildet werden kann. Auf diese Weise kann die Gefahr einer Beschädigung des Federmittels und der erforderliche Materialbedarf des Federmittels verringert werden kann. Das verbleibende Differenzspiel zwischen den Schienen wird also durch den an der anderen Schiene angeordneten Vorsprung ausgeglichen, welcher im montierten Zustand der Schienen am Federelement spielfrei anliegt.In other words, in the connected state of the two rails, the spring means of one rail rests on the projection of the other rail, so that the spring means can be designed with a reduced, for example approximately half, structural height on a rail. In this way, the risk of damage to the spring means and the necessary material requirements for the spring means can be reduced. The remaining difference play between the rails is thus compensated for by the projection arranged on the other rail, which in the assembled state of the rails rests on the spring element without play.
Gemäß einem Ausführungsbeispiel ist die erste Schiene ausgehend von einem vorderen Endbereich der zweiten Schiene zu einem hinteren Endbereich der zweiten Schiene aufschiebbar, wobei der wenigstens eine Vorsprung nur über einen dem hinteren Endbereich der zweiten Schiene unmittelbar vorgelagerten Teilbereich mit dem zumindest einen Federmittel zusammenwirkt. Dies hat den besonderen Vorteil, dass die Schublade mit der ersten Schiene über einen Großteil des Aufschiebeweges mit einem reduzierten Reibungswiderstand relativ zur zweiten Schiene bewegbar ist, ohne dass dabei ein an einer Schiene schleifendes Federmittel den Reibungswiderstand erhöht. Erst gegen Ende des Aufschiebeweges treten das Federmittel und der Vorsprung miteinander in Kontakt und kompensieren durch gegenseitiges Aneinanderliegen das Spiel zwischen den beiden Schienen.According to one embodiment, the first rail can be pushed open from a front end region of the second rail to a rear end region of the second rail, the at least one projection interacting with the at least one spring means only over a partial region immediately in front of the rear end region of the second rail. This has the particular advantage that the drawer with the first rail can be moved relative to the second rail over a large part of the sliding path with reduced frictional resistance, without a spring means dragging against a rail increasing the frictional resistance. Only towards the end of the sliding path do the spring means and the projection come into contact with one another and compensate for the play between the two rails by resting against one another.
Die erste Schiene und die zweite Schiene können jeweils zumindest einen in Längsrichtung der Schienen verlaufenden Seitenschenkel aufweisen, wobei das zumindest eine Federmittel und der wenigstens eine Vorsprung jeweils an einem Seitenschenkel der Schienen angeordnet oder ausgebildet sind. Dabei kann vorgesehen sein, dass das zumindest eine Federmittel und der wenigstens eine Vorsprung jeweils von den Seitenschenkeln der Schienen quer abstehen.The first rail and the second rail can each have at least one side leg running in the longitudinal direction of the rails, the at least one spring means and the at least one projection being arranged or formed on a side leg of the rails. It can be provided that the at least one spring means and the at least one projection each protrude transversely from the side legs of the rails.
Bei einer konstruktiv einfachen Ausführung kann vorgesehen sein, dass das zumindest eine Federmittel und/oder der wenigstens eine Vorsprung mit den Schienen einstückig ausgebildet ist oder sind.In a structurally simple embodiment, it can be provided that the at least one spring means and / or the at least one projection is or are formed in one piece with the rails.
Das zumindest eine Federmittel kann in einer quer zur Längsrichtung der Schiene verlaufenden Richtung elastisch verbiegbar oder reversibel verformbar ausgebildet sein, wobei vorzugsweise vorgesehen ist, dass das zumindest eine Federmittel in Form einer Federlasche oder Federzunge an einer der Schienen ausgebildet ist. Die Federlasche oder Federzunge kann beispielsweise aus einem metallischen Material einer Schiene ausgestanzt sein. Alternativ ist es möglich, dass das Federmittel zumindest ein mechanisches Federelement (beispielsweise eine Druckfeder) aufweist.The at least one spring means can be designed to be elastically bendable or reversibly deformable in a direction running transversely to the longitudinal direction of the rail, whereby it is preferably provided that the at least one spring means is designed in the form of a spring tab or spring tongue on one of the rails. The spring tab or spring tongue can, for example, be punched out of a metallic material of a rail. Alternatively, it is possible for the spring means to have at least one mechanical spring element (for example a compression spring).
Der wenigstens eine Vorsprung kann in einer quer zur Längsrichtung der Schiene verlaufenden Richtung im Wesentlichen starr ausgebildet sein, wobei vorzugsweise vorgesehen ist, dass der wenigstens eine Vorsprung in Form einer Prägung an einer der Schienen ausgebildet ist. Alternativ ist es möglich, dass der Vorsprung ebenfalls elastisch nachgiebig ausgebildet ist und/oder an einer Schiene (beispielsweise durch Anschrauben oder Verkleben) befestigt ist.The at least one protrusion can be designed essentially rigid in a direction running transversely to the longitudinal direction of the rail, whereby it is preferably provided that the at least one protrusion is designed in the form of an embossing on one of the rails. Alternatively, it is possible that the projection is also designed to be elastically flexible and / or is attached to a rail (for example by screwing or gluing).
Gemäß einem Ausführungsbeispiel kann vorgesehen sein, dass an der ersten oder zweiten Schiene zumindest zwei in Längsrichtung der Schiene voneinander beabstandete Federmittel angeordnet sind, welche im verbundenen Zustand der ersten und zweiten Schiene mit zumindest zwei in Längsrichtung voneinander beabstandeten Vorsprüngen der anderen Schiene zusammenwirken. Die zwei Schienen sind dann zumindest in jenen Bereichen, in welchen die zumindest zwei voneinander in Längsrichtung beabstandeten Federmittel an den ihnen zugeordneten Vorsprüngen anliegen, in einer quer zur Längsrichtung verlaufenden Richtung spielfrei zueinander angeordnet.According to one embodiment it can be provided that at least two spring means are arranged on the first or second rail, spaced apart from one another in the longitudinal direction of the rail, which spring means, in the connected state of the first and second rails, are arranged with at least two in the longitudinal direction from one another cooperate spaced projections of the other rail. The two rails are then at least in those areas in which the at least two spring means spaced apart from one another in the longitudinal direction bear against the projections assigned to them, in a direction running transversely to the longitudinal direction without play relative to one another.
Die zumindest zwei Federmittel und/oder die zumindest zwei Vorsprünge können jeweils eine unterschiedliche Höhe aufweisen. Gemäß einer ersten Variante kann vorgesehen sein, dass beim Aufschieben der ersten Schiene auf die zweite Schiene ein Federmittel mit geringerer Höhe an einem Vorsprung mit geringerer Höhe vorbeibewegbar ist, wobei im verbundenen Zustand der ersten und zweiten Schiene das Federmittel geringerer Höhe an einem Vorsprung mit größerer Höhe anliegt.The at least two spring means and / or the at least two projections can each have a different height. According to a first variant, it can be provided that when the first rail is pushed onto the second rail, a spring means with a lower height can be moved past a projection with a lower height, wherein in the connected state of the first and second rails the spring means with a lower height can be moved past a projection with a greater height Height is applied.
Gemäß einer zweiten Variante kann vorgesehen sein, dass beim Aufschieben der ersten Schiene auf die zweite Schiene ein Vorsprung mit geringerer Höhe an einem Federmittel mit geringerer Höhe vorbeibewegbar ist, wobei im verbundenen Zustand der ersten und zweiten Schiene der Vorsprung mit geringerer Höhe an einem Federmittel mit größerer Höhe anliegt.According to a second variant, it can be provided that when the first rail is pushed onto the second rail, a projection with a lower height can be moved past a spring means with a lower height, the lower-height projection with a spring means in the connected state of the first and second rails greater height.
Diese beiden Varianten haben den Vorteil, dass die Schublade auf die zweite Schiene für eine Person leichtgängig aufschiebbar ist, da der Vorsprung und das Federmittel, vorzugsweise unter Bildung eines Spaltes oder allenfalls nur mit einer geringen Reibung, aneinander vorbeibewegbar sind und erst im verbundenen Zustand oder unmittelbar vor Erreichen des verbundenen Zustandes eine spielfreie Verbindung zwischen den beiden Schienen durch die an den Federmitteln anliegenden Vorsprünge hergestellt wird.These two variants have the advantage that the drawer can easily be slid onto the second rail for one person, since the projection and the spring means can be moved past one another, preferably with the formation of a gap or at most only with little friction, and only in the connected state or immediately before the connected state is reached, a backlash-free connection between the two rails is established by the projections resting on the spring means.
Die erfindungsgemäße Schubladenausziehführung weist eine an einem Möbelkorpus zu befestigende Korpusschiene und zumindest eine Ladenschiene der beschriebenen Art auf, wobei die Ladenschiene relativ zur Korpusschiene verfahrbar gelagert ist. Um einen Vollauszug der Schublade relativ zum Möbelkorpus zu ermöglichen, kann eine zusätzliche Mittelschiene vorgesehen sein, welche zwischen der Korpusschiene und der Ladenschiene verschiebbar gelagert ist.The pull-out drawer slide according to the invention has a carcass rail to be fastened to a furniture carcass and at least one drawer rail of the type described, the drawer rail being relative to the carcass rail is movably mounted. In order to enable the drawer to be fully extended relative to the furniture carcass, an additional central rail can be provided, which is mounted displaceably between the carcass rail and the drawer rail.
Das erfindungsgemäße Möbel weist einen Möbelkorpus und eine relativ zum Möbelkorpus verfahrbar gelagerte Schublade auf, wobei die erste Schiene an der Schublade und die zweite Schiene am Möbelkorpus vormontiert sind, wobei die mit der Schublade verbundene erste Schiene durch Aufschieben auf die zweite Schiene mit der zweiten Schiene verbindbar ist.The furniture according to the invention has a furniture body and a drawer mounted so as to be movable relative to the furniture body, the first rail being preassembled on the drawer and the second rail being preassembled on the furniture body, the first rail connected to the drawer being pushed onto the second rail with the second rail is connectable.
