Description

Die vorliegende Erfindung betrifft eine Kurvenführung, insbesondere für einen Selbsteinzug, nach dem Oberbegriff des Anspruches 1.The present invention relates to a curve guide, in particular for a self-closing, according to the preamble of claim 1.

Es gibt Selbsteinzüge für Schubkästen, bei denen an einem Möbelkorpus ein Gehäuse mit einer Führungsbahn für einen Mitnehmer vorgesehen ist. Der entlang der Führungsbahn bewegbare Mitnehmer kann über einen Einzugsbereich mit einem stegförmigen Aktivator gekoppelt werden, der mit einer Laufschiene einer Auszugsführung verbunden ist. Der Mitnehmer ist dabei in eine Schließposition vorgespannt, so dass ein Schubkasten in der Schließposition gehalten wird und nicht versehentlich leicht geöffnet wird. Für eine Entkopplung des Mitnehmers wird dieser bis zu einem Ende der Führungsbahn verfahren und dort an einem abgewinkelten Endabschnitt verschwenkt, so dass der Aktivator aus der Aufnahme heraus bewegt werden kann und dann unabhängig von dem geparkten Mitnehmer verfahren werden kann. Solche Selbsteinzüge haben sich an sich bewährt, allerdings besteht das Problem, dass aufgrund erheblicher Toleranzen ein Einkoppeln nicht immer sicher gewährleistet werden kann. Zudem können die Bauteile aufgrund von Toleranzen und Stoßbelastungen beschädigt werden, was ebenfalls Fehlfunktionen verursachen kann.There are Selbsteinzüge for drawers, in which a housing with a guideway for a driver is provided on a furniture body. The movable along the guide track carrier can be coupled via a catchment area with a web-shaped activator, which is connected to a running rail of a pullout guide. The driver is biased into a closed position, so that a drawer is held in the closed position and is not accidentally easily opened. For a decoupling of the driver this is moved to one end of the guideway and there pivoted at an angled end portion, so that the activator can be moved out of the receptacle and then can be moved independently of the parked driver. Such Selbsteinzüge have proven themselves, but there is the problem that due to considerable tolerances coupling can not always be guaranteed safe. In addition, the components can be damaged due to tolerances and shock loads, which can also cause malfunction.

Die EP 1 705 330 offenbart eine Dämpfungsvorrichtung für eine Schiebetür, bei der ein Mitnehmer entlang einer Führungsbahn bewegbar ist. Der Mitnehmer ist dabei durch die Kraft einer Feder in Einzugsrichtung vorgespannt und zudem mit einem Dämpfer gekoppelt, um die Schließbewegung abzubremsen. Um den Mitnehmer zu verfahren, ist an dem bewegbaren Möbelteil ein zapfenförmiger Aktivator angebracht, der in eine Aufnahme des Aktivators bewegbar ist, allerdings aufgrund der zapfenförmigen Form auch in axiale Richtung des Zapfens in der Aufnahme verschoben werden kann.The EP 1 705 330 discloses a damper device for a sliding door in which a driver is movable along a guideway. The driver is biased by the force of a spring in the feed direction and also coupled with a damper to decelerate the closing movement. In order to move the driver, a pin-shaped activator is mounted on the movable furniture part, which is movable in a receptacle of the activator, but can be moved due to the peg-shaped shape in the axial direction of the pin in the receptacle.

Es ist daher Aufgabe der vorliegenden Erfindung, eine Kurvenführung zu schaffen, die in sicheres Einkoppeln eines Aktivators an dem Mitnehmer gewährleistet.It is therefore an object of the present invention to provide a cam guide, which ensures safe coupling of an activator on the driver.

Diese Aufgabe wird mit einer Kurvenführung mit den Merkmalen des Anspruches 1 gelöst.This object is achieved with a curve guide with the features of claim 1.

Erfindungsgemäß weist die Führungsbahn zumindest benachbart zu dem abgewinkelten Endabschnitt eine Abdeckung auf, mittels der der Aktivator an einer Bewegung aus der Aufnahme heraus gehindert ist. Dadurch kann während der Einkopplung des Aktivators an dem Mitnehmer eine Fehlfunktion vermieden werden, da der Aktivator in diesem Bereich zwangsgeführt ist und die Abdeckung eine Bewegung senkrecht zur Führungsbahn verhindert. Dadurch kann auch bei größeren Toleranzen eine Fehlfunktion sicher vermieden werden.According to the invention, the guideway at least adjacent to the angled end portion on a cover, by means of which the activator is prevented from moving out of the receptacle out. As a result, a malfunction can be avoided during the coupling of the activator to the driver, since the activator is constrained in this area and the cover prevents movement perpendicular to the guideway. As a result, a malfunction can be safely avoided even with larger tolerances.

Erfindungsgemäß erstreckt sich die Abdeckung im Wesentlichen parallel zur Führungsbahn. Für eine sichere Führung des Aktivators kann die Abdeckung in Öffnungsrichtung eine Einlaufschräge aufweisen, die sich zu dem Mitnehmer an dem abgewinkelten Endabschnitt in verjüngt. Die Einlaufschräge kann dabei Teil eines Einlauftrichters sein, so dass der Aktivator von dem Einlauftrichter und der Abdeckung eingefangen wird.According to the invention, the cover extends substantially parallel to the guide track. For a safe guidance of the activator, the cover in the opening direction may have an inlet slope, which tapers towards the driver on the angled end section. The inlet slope can be part of an inlet funnel, so that the activator is captured by the inlet funnel and the cover.

Gemäß einer Ausgestaltung erstreckt sich die Abdeckung über die gesamte Länge der Führungsbahn. Dadurch kann eine Fehlfunktion durch ein Herausspringen des Aktivators in jedem Bereich der Kurvenführung sicher vermieden werden. Die Abdeckung kann dabei für einen kompakten Aufbau der Kurvenführung integral mit dem Gehäuse ausgebildet sein.According to one embodiment, the cover extends over the entire length of the guideway. Thereby, a malfunction can be safely avoided by jumping out of the activator in each area of the curve guide. The cover may be formed integrally with the housing for a compact construction of the cam guide.

Vorzugsweise ist der Aktivator an einer Laufschiene einer Auszugsführung oder einem bewegbaren Bauteil, wie einem Schubkasten, fixiert. Die Kurvenführung kann dann für einen Selbsteinzug, eine Ausstoßvorrichtung oder ein anderes Beschlagsteil eingesetzt werden, bei dem eine Kurvenführung benötigt wird.Preferably, the activator is fixed to a running rail of a pullout guide or a movable component, such as a drawer. The cam guide can then be used for a self-closing mechanism, an ejection device or another fitting part, in which a curve guide is needed.

Vorzugsweise weist der Aktivator einen Vorsprung auf, der in die Aufnahme des Mitnehmers einfügbar ist, der benachbart zu dem Mitnehmer an dem Gehäuse geführt ist. Der Vorsprung kann beispielsweise an mindestens einem federnden Steg des Aktivators gehalten sein, wobei der Steg an einem Schlitz parallel zur Führungsbahn gehalten ist. Dadurch kann der Abstand zwischen dem Aktivator und dem Vorsprung im Wesentlichen konstant gehalten werden.Preferably, the activator has a projection which can be inserted into the receptacle of the driver, which is guided adjacent to the driver on the housing. The projection may be held for example on at least one resilient web of the activator, wherein the web is held on a slot parallel to the guide track. Thereby, the distance between the activator and the projection can be kept substantially constant.

Für eine federnde Aufhängung des Vorsprunges kann dieser an einem Quersteg gehalten sein, der sich im Wesentlichen senkrecht zur Führungsbahn erstreckt. Dieser Quersteg kann dann an dem Schlitz des Gehäuses geführt sein.For a resilient suspension of the projection, this can be held on a transverse web, which extends substantially perpendicular to the guide track. This crosspiece can then be guided on the slot of the housing.

Vorzugsweise ist der Vorsprung bei einer Stoßbelastung mindestens um 1 mm elastisch federnd an dem mindestens einen federnden Steg gehalten. Der Steg kann dabei einen Federabschnitt aufweisen, beispielsweise durch ein oder mehrere biegbare Abschnitte.Preferably, the projection is held at a shock load at least 1 mm elastically resiliently on the at least one resilient web. The web can have a spring section, for example by one or more bendable sections.

Für eine einfache Montage kann der Aktivator an dem bewegbaren Bauteil, insbesondere einem Schubkasten, verrastet sein. Hierfür können an einer Seitenwand des Schubkastens entsprechende Rastelemente ausgebildet werden.For ease of assembly of the activator on the movable component, in particular a drawer, be locked. For this purpose, corresponding latching elements can be formed on a side wall of the drawer.

Eine Kurvenführung 1 für einen Selbsteinzug umfasst ein Gehäuse 2, an dem eine Führungsbahn 3 für einen Mitnehmer 4 ausgebildet ist. An dem Gehäuse 2 ist ein Einzugsgehäuse 5 mit einer Einzugsfeder montiert. Das Gehäuse 2 ist dabei an einer Seitenwand 6 eines Möbelkorpus angebracht und benachbart zu einer Auszugsführung 7 angeordnet, die eine stationäre Führungsschiene 10, eine Mittelschiene 9 sowie eine Laufschiene 8 aufweist.A curve guide 1 for a self-closing comprises a housing 2, on which a guide track 3 for a driver 4 is formed. On the housing 2, a feeder housing 5 is mounted with a pull-in spring. The housing 2 is attached to a side wall 6 of a furniture body and arranged adjacent to a pullout guide 7, which has a stationary guide rail 10, a middle rail 9 and a running rail 8.

Wie in Figur 2 gezeigt ist, umfasst die Führungsbahn 3 für den Mitnehmer 4 einen linearen Abschnitt 45 und einen abgewinkelten Endabschnitt 46. In der Führungsbahn 3 ist der Mitnehmer 4 mit einem vorderen Zapfen 44 und einen hinteren Zapfen 43 geführt. Der Mitnehmer 4 weist eine im Wesentlichen U-förmige Aufnahme 40 auf, die durch eine vordere Seitenwand 42 und eine hintere Seitenwand 41 begrenzt ist.As in FIG. 2 is shown, the guide track 3 for the driver 4 comprises a linear portion 45 and an angled end portion 46. In the guide track 3, the driver 4 is guided with a front pin 44 and a rear pin 43. The driver 4 has a substantially U-shaped receptacle 40 which is bounded by a front side wall 42 and a rear side wall 41.

Benachbart zu der Führungsbahn 3 ist eine leistenförmige Abdeckung 21 an dem Gehäuse 2 ausgebildet, die sich parallel zu dem linearen Abschnitt 45 erstreckt. Auf der Seite in Öffnungsrichtung befindet sich ein Einlauftrichter 22, der einen Aktivator zu dem Mitnehmer 4 führen kann. Ferner ist an dem Gehäuse 2 mindestens ein Steg 23 zur Fixierung an einem Winkel oder der Führungsschiene 10 vorgesehen.Adjacent to the guide track 3, a strip-shaped cover 21 is formed on the housing 2, which extends parallel to the linear portion 45. On the side in the opening direction is an inlet funnel 22, which can lead an activator to the driver 4. Further, at least one web 23 is provided for fixing to an angle or the guide rail 10 on the housing 2.

An dem Gehäuse 2 ist ferner ein Stutzen 24 angeformt, der mit dem Einzugsgehäuse 5 verrastbar ist. In dem Einzugsgehäuse 5 ist eine Einzugsfeder angeordnet, die eine Kolbenstange 11 in Schließrichtung beaufschlagt. Die Kolbenstange 11 ist an einem Ende mit einem Rastelement 12 verbunden, das mit dem Mitnehmer 4 verrastet ist.On the housing 2, a connecting piece 24 is further formed, which is latched to the feeder housing 5. In the feeder housing 5, a collection spring is arranged, which acts on a piston rod 11 in the closing direction. The piston rod 11 is connected at one end with a latching element 12 which is latched to the driver 4.

In Figur 3 ist ein Schubkasten 50 gezeigt, der an gegenüberliegenden Seiten eine Seitenwand 51 aufweist, die einen Hohlraum aufweist, in dem eine Auszugsführung 7 angeordnet ist. Dabei ist der Schubkasten 50 mit der Laufschiene 8 verbunden und kann linear verfahren werden.In FIG. 3 a drawer 50 is shown having on opposite sides a side wall 51 having a cavity in which a pullout guide 7 is arranged. In this case, the drawer 50 is connected to the running rail 8 and can be moved linearly.

An den Seitenwänden 51 ist ein Aktivator 30 verrastet, der einen Vorsprung 31 aufweist, der mit dem Mitnehmer 4 koppelbar ist. Der Vorsprung 31 ist an einem Quersteg 37 gehalten, der sich senkrecht zur Längsrichtung der linearen Führungsbahn 45 erstreckt. An den Quersteg 37 schließt sich ein Federsteg 32 an, der endseitig mit einem Körper des Aktivators 30 verbunden ist. Der Aktivator 30 besitzt ferner einen Steg 33, der an einer Lasche 34 an der Seitenwand 51 verrastet ist.On the side walls 51, an activator 30 is locked, which has a projection 31 which can be coupled to the driver 4. The projection 31 is held on a transverse web 37, which extends perpendicular to the longitudinal direction of the linear guide track 45. At the transverse web 37, a spring bar 32 connects, which is connected at the end to a body of the activator 30. The activator 30 further has a web 33 which is latched to a tab 34 on the side wall 51.

Wie in Figur 4 gezeigt ist, umfasst der Aktivator 30 ferner einen horizontal verlaufenden Raststeg 35, der in einen gebogenen Abschnitt 36 an der Seitenwand 51 eingesteckt ist, so dass der Aktivator 30 über Steckverbindungen an der Seitenwand 51 klemmend und/oder rastend festgelegt ist. Da an der Seitenwand 51 eine Vielzahl von gebogenen Abschnitten 36 ausgebildet sind, kann der Aktivator 30 an unterschiedlichen Positionen an der Seitenwand 51 montiert werden.As in FIG. 4 is shown, the activator 30 further comprises a horizontally extending latching web 35 which is inserted into a bent portion 36 on the side wall 51, so that the activator 30 is fixed by means of plug connections on the side wall 51 clamping and / or latching. Since a plurality of bent portions 36 are formed on the side wall 51, the activator 30 can be mounted at different positions on the side wall 51.

In Figur 5 ist der Schubkasten 50 in einer Öffnungsposition ohne den Möbelkorpus dargestellt. Der Schubkasten 50 ist an der Laufschiene 7 frei verfahrbar und der Aktivator 30 befindet sich beabstandet von dem Gehäuse 2.In FIG. 5 the drawer 50 is shown in an open position without the furniture body. The drawer 50 is freely movable on the running rail 7 and the activator 30 is located at a distance from the housing 2.

In den Figuren 6A und 6B ist die Position des Aktivators 30 dargestellt, in der der Vorsprung 31 in den Einlauftrichter 22 an dem Gehäuse 2 einfährt. Der Vorsprung 31 läuft beabstandet von den Wänden an dem Einlauftrichter 22 ein, kann aber bei einer ungenauen Justierung durch den Einlauftrichter 22 zwangsgeführt werden, damit der Vorsprung 31 in einer bestimmten Höhe relativ zu dem Mitnehmer 4 verfahren wird. Der Vorsprung 31 wird nun in die Aufnahme 40 des geparkten Mitnehmers 4 verfahren, bis der Vorsprung 31 an der Seitenwand 41 anliegt und den Mitnehmer 4 aus dem abgewinkelten Endabschnitt 46 der Führungsbahn 3 herauszieht. Dann ist der Vorsprung 31 und damit der Aktivator 30 fest mit dem Mitnehmer 4 gekoppelt, der nun nach der Entriegelung durch die Kraft einer Einzugsfeder in Schließrichtung gezogen wird. Der Benutzer kann nun den Schubkasten 50 loslassen und der Schubkasten 50 wird automatisch in die Schließposition bewegt. Dabei gleitet der Quersteg 37 an dem Aktivator 30 in dem Schlitz 20 des Gehäuses 2 entlang, wobei die leistenförmige Abdeckung 21 dafür sorgt, dass der Vorsprung 31 sich nicht aus der Aufnahme 40 des Mitnehmers 4 heraus bewegen kann.In the FIGS. 6A and 6B the position of the activator 30 is shown, in which the projection 31 enters the inlet funnel 22 on the housing 2. The projection 31 is spaced from the walls at the inlet funnel 22, but can be forcibly guided in an inaccurate adjustment by the inlet funnel 22, so that the projection 31 is moved at a certain height relative to the driver 4. The projection 31 is now moved into the receptacle 40 of the parked driver 4 until the projection 31 bears against the side wall 41 and pulls the driver 4 out of the angled end portion 46 of the guide track 3. Then the projection 31 and thus the activator 30 is fixedly coupled to the driver 4, which is now pulled after unlocking by the force of a catch spring in the closing direction. The user can now release the drawer 50 and the drawer 50 is automatically moved to the closed position. In this case, the transverse web 37 slides along the activator 30 in the slot 20 of the housing 2, wherein the strip-shaped cover 21 ensures that the projection 31 can not move out of the receptacle 40 of the driver 4 out.

In Figur 7 ist die Schließposition der Kurvenführung gezeigt, bei der der Vorsprung 31 zusammen mit dem Aktivator 4 in einem Endbereich der linearen Führungsbahn 45 angeordnet ist. Wenn der Benutzer nun den Schubkasten 50 in Öffnungsrichtung zieht, wird der Vorsprung 31 durch die Abdeckung 21 geführt, während der Mitnehmer 4 entlang der parallelen linearen Führungsbahn 45 bis zu dem abgewinkelten Endabschnitt bewegt wird. Dort wird der Mitnehmer 4 verschwenkt und der Vorsprung 31 aus der Aufnahme 40 heraus bewegt, damit der Schubkasten 50 wieder in einem Öffnungsbereich frei verfahren werden kann.In FIG. 7 the closing position of the cam guide is shown, in which the projection 31 is arranged together with the activator 4 in an end region of the linear guide track 45. When the user now pulls the drawer 50 in the opening direction, the projection 31 is guided by the cover 21, while the driver 4 is moved along the parallel linear guide path 45 up to the angled end portion. There, the driver 4 is pivoted and the projection 31 moves out of the receptacle 40, so that the drawer 50 can be moved freely again in an opening area.

In den Figuren 8A und 8B ist eine modifizierte Ausgestaltung eines Aktivators 30' gezeigt, bei dem die Befestigung an einer Seitenwand 51 des Schubkastens wie bei dem vorangegangenen Ausführungsbeispiel über einen Vorsprung 33 und einen Rastvorsprung 35 erfolgt. Bei diesem Aktivator 30' ist der Vorsprung 31 zunächst über einen Quersteg 37 gehalten und anschließend über zwei Federstege 32', die gebogen ausgebildet sind und eine ovale Öffnung 39' umschließen. Dadurch kann der Vorsprung 31 besonders federnd angeordnet werden, was eine Stoßbelastung bei hoher Schließgeschwindigkeit des Schubkastens 50 vermeidet. Der Vorsprung 31 kann in Bewegungsrichtung der Laufschiene 8 elastisch federnd angeordnet sein, vorzugsweise um einen Federweg größer als 1 mm. Dadurch wird die Materialbelastung gering gehalten.In the FIGS. 8A and 8B a modified embodiment of an activator 30 'is shown in which the attachment to a side wall 51 of the drawer as in the previous embodiment via a projection 33 and a latching projection 35 takes place. In this activator 30 ', the projection 31 is first held over a transverse web 37 and then over two spring webs 32', which are formed bent and an oval opening 39 'enclose. As a result, the projection 31 can be arranged particularly resiliently, which avoids impact load at high closing speed of the drawer 50. The projection 31 may be arranged resiliently in the direction of movement of the running rail 8, preferably by a spring travel greater than 1 mm. As a result, the material load is kept low.

In den Figuren 9A und 9B ist eine weitere Ausführungsform eines Aktivators 30" gezeigt, bei dem zwei modifizierte Federstege 32" zur Lagerung des Vorsprunges 31 und des Quersteges 37 vorgesehen sind. Die beiden Federstege 32" sind V-förmig angeordnet und umschließen eine V-förmige Öffnung 39". Dadurch kann der Vorsprung 31 in Bewegungsrichtung der Laufschiene 8 ebenfalls federnd aufgehängt sein.In the FIGS. 9A and 9B is a further embodiment of an activator 30 "shown in which two modified spring bars 32" are provided for supporting the projection 31 and the transverse web 37. The two spring webs 32 "are arranged in a V-shape and enclose a V-shaped opening 39". Thereby, the projection 31 may also be suspended resiliently in the direction of movement of the running rail 8.

In den dargestellten Ausführungsbeispielen ist der Aktivator 30, 30', 30" direkt an der Seitenwand eines Schubkastens angebracht. Es ist natürlich auch möglich, den Aktivator 30 an einer Laufschiene 8 einer Auszugsführung 7 festzulegen.In the exemplary embodiments illustrated, the activator 30, 30 ', 30 "is mounted directly on the side wall of a drawer, it being of course also possible to fix the activator 30 on a running rail 8 of a drawer guide 7.

Zudem kann die erfindungsgemäße Kurvenführung nicht nur für einen Selbsteinzug eingesetzt werden, sondern auch für eine Ausstoßvorrichtung, beispielsweise für bewegbare Möbelteile oder für andere Einsatzzwecke.In addition, the curve guide according to the invention can be used not only for a self-closing, but also for an ejection device, for example for movable furniture parts or for other purposes.
