A stopping bevel is formed adjacent to the locking position for the catch. A run-off area is formed on the control cam for the catch, in which the catch is moved away from the receptacle. An independent claim is also included for furniture with a furniture body.

Description

Die vorliegende Erfindung betrifft einen Rastmechanismus, insbesondere für eine Auszugsführung, mit einem Mitnehmer, der entlang einer Steuerkurve bewegbar ist, und in einer Rastposition über eine Feder in eine Aufnahme an der Steuerkurve vorgespannt ist, wobei benachbart zu der Rastposition mindestens eine Anlaufschräge für den Mitnehmer ausgebildet ist, sowie ein Möbel.The present invention relates to a latching mechanism, in particular for a pullout guide, with a driver, which is movable along a control cam, and is biased in a latching position via a spring in a receptacle on the control cam, wherein adjacent to the latching position at least one run-on slope for the driver is formed, as well as a piece of furniture.

Aus der EP 1845821 ist eine Schließ- und Öffhungsvomchtung für Schubladen bekannt, bei der zum Halten der Schublade in einer Schließposition ein Rastmechanismus vorgesehen ist. Der Rastmechanismus umfasst einen durch eine Feder vorgespannten Hebel, der entlang einer Steuerkurve bewegbar ist. Dabei kann der Hebel in einer Rastposition gehalten werden, aus der er beim Öffnen der Schublade gegen eine Anlaufschräge gedrückt wird, um dann entlang der Steuerkurve bewegt zu werden. Bei diesem Rastmechanismus ist nachteilig, dass toleranzbedingte Änderungen des Spaltes zwischen Frontblende und Möbel nicht ausgeglichen werden können. Zudem kann es bei breiten Schubkasten passieren, dass ein schräges Eindrücken des Schubkastens erfolgt, was auf der einen Seite den Rastmechanismus entriegelt und auf der anderen Seite noch keine Entriegelung bewirkt. Zudem kann bei einem starken Eindrücken der Hebel an einem Ende der Steuerkurve anschlagen und beschädigt werden.From the EP 1845821 is a closing and Öffvungsvomchtung known for drawers, in which a latching mechanism is provided for holding the drawer in a closed position. The latching mechanism comprises a lever biased by a spring which is movable along a control cam. In this case, the lever can be held in a latching position, from which it is pressed when opening the drawer against a run-on slope, and then to be moved along the control cam. In this locking mechanism is disadvantageous that tolerance-related changes in the gap between the front panel and furniture can not be compensated. In addition, it can happen with wide drawer, that an oblique pressing of the drawer takes place, which unlocks on one side of the locking mechanism and on the other side still causes no unlocking. In addition, the lever can strike at one end of the control cam and be damaged in a strong impressions.

Es ist daher Aufgabe der vorliegenden Erfindung, einen Rastinechauisnws zu schaffen, der einen Toleranzausgleich beim Einbau eines Schubkastens an einem Möbelkorpus ermöglicht und zudem auch bei breiten Schubkästen ein sicheres Öffnen gewährleistet.It is therefore an object of the present invention to provide a Rastinechauisnws that allows tolerance compensation when installing a drawer on a furniture body and also ensures safe opening even with wide drawers.

Diese Aufgabe wird mit einem Rastmechanismus mit den Merkmalen des Anspruches 1 gelöst.This object is achieved with a locking mechanism having the features of claim 1.

Erfindungsgemäß ist an der Anlaufschräge benachbart zu der Aufnahme für die Rastposition eine Auslaufzone für den Mitnehmer an der Steuerkurve ausgebildet, in die der Mitnehmer weg von der Aufnahme bewegbar ist, so dass der Mitnehmer so weit wie notwendig in die Auslaufzone bewegt werden kann, ohne dass er an ein Ende der Steuerkurve anschlägt. Dadurch kann sowohl bei der Montage einer Ausziehführung an einem Möbelkorpus als auch bei einer Verstellung der Position der Frontblende relativ zu dem Möbelkorpus ein Toleranzausgleich durch die Auslaufzone erfolgen, da der Mitnehmer quasi ohne Endanschlag in die Auslaufzone hineinbewegt werden kann. Zudem kann auch bei besonders breiten Schubkästen die Bewegung des Mitnehmers an gegenüberliegenden Seiten unterschiedlich stark sein, so dass auch ein über das Entriegeln hinaus notwendiges Einfahren des Mitnehmers in die Auslaufzone möglich ist.According to the invention, an outlet zone for the driver on the control cam is formed on the starting bevel adjacent to the receptacle for the detent position, into which the driver is movable away from the receptacle, so that the driver can be moved as far as necessary in the outlet zone, without he strikes an end of the cam. As a result, both in the assembly of a pull-out on a furniture body as well as an adjustment of the position of the front panel relative to the furniture body tolerance compensation done by the outlet zone, since the driver can be moved almost without end stop in the outlet zone. In addition, even with very wide drawers, the movement of the driver on opposite sides be different strong, so that even beyond the unlocking necessary retraction of the driver in the outlet zone is possible.

Vorzugsweise umfasst die mindestens eine Auslaufzone einen Kanalabschnitt, in den der Mitnehmer hin- und herbewegbar ist. Dadurch kann in der Auslaufzone eine seitliche Bewegung des Mitnehmers vermieden werden, so dass die Auslaufzone in Einschubrichtung wirksam ist.Preferably, the at least one outlet zone comprises a channel section into which the driver can be moved back and forth. As a result, a lateral movement of the driver can be avoided in the outlet zone, so that the outlet zone in the direction of insertion is effective.

In einer Ausgestaltung der Erfindung sind zwei voneinander beabstandete Auslaufzonen an der Steuerkurve ausgebildet, wobei eine Auslaufzone vor der Rastposition und eine Auslaufzone nach der Rastposition wirksam ist. Dadurch kann sowohl beim Öffnen als auch beim Schließen eine gewisse Schrägstellung ausgeglichen werden.In one embodiment of the invention, two spaced outlet zones are formed on the control cam, wherein an outlet zone before the detent position and an outlet zone after the detent position is effective. As a result, a certain inclination can be compensated both when opening and when closing.

Vorzugsweise weitet sich die Auslaufzone in eine Richtung weg von der Rastposition auf. Dadurch kann im Bereich der Auslaufzone eine Tasche ausgebildet werden, in der sich Verunreinigungen, beispielsweise durch Abrieb bei der Bewegung des Mitnehmers in der Steuerkurve, ansammeln können.Preferably, the outlet zone widens in a direction away from the latching position. As a result, a pocket can be formed in the region of the outlet zone in which contaminants, for example by abrasion during the movement of the driver in the control curve, can accumulate.

Erfindungsgemäß wird auch ein Möbel bereitgestellt, bei dem mindestens ein Schubkasten verschiebbar an einem Möbelkorpus gelagert ist, wobei an gegenüberliegenden Seiten eine Auszugsführung mit einem erfindungsgemäßen Rastmechanismus vorgesehen ist. Vorzugsweise ist dabei die Länge der Auslaufzonen an den beiden Rastmechanismen größer als der Abstand einer Frontblende des Schubkastens zum Möbelkorpus in Schließposition. Vorzugsweise ist bei allen Auslaufzonen der Abstand zwischen der Aufnahme der Rastposition und dem Ende der Auslaufzone größer als der Abstand der Frontblende des Schubkastens zum Möbelkorpus.According to the invention, a piece of furniture is also provided in which at least one drawer is displaceably mounted on a furniture carcass, a pull-out guide having a latching mechanism according to the invention being provided on opposite sides. Preferably, the length of the outlet zones at the two locking mechanisms is greater than the distance of a front panel of the drawer to the furniture body in the closed position. Preferably, the distance between the recording of the detent position and the end of the outlet zone is greater than the distance of the front panel of the drawer to the furniture body in all outlet zones.

Eine Auszugsführung 1 umfasst eine an einem Möbelkorpus festlegbare Führungsschiene 2, an der eine Laufschiene 3 verfahrbar gelagert ist. Zur Erzielung eines Vollauszuges kann zwischen der Führungsschiene 2 und der Laufschiene 3 mindestens eine Mittel schiene 28 angeordnet sein. An der Laufschiene 3 ist ein Aktivator 4 festgelegt, der in eine Aufnahme an einem Mitnehmer 5 eingreift. Der Mitnehmer 5 ist an einer Laufbahn 6 mit abgebogenem Endabschnitt verfahrbar gelagert, wobei die Laufbahn 6 an einem Gehäuse 7 ausgebildet ist, das fest mit der Führungsschiene 2 verbunden ist. An dem Gehäuse 7 ist ein Federelement 8 angebracht.A pullout guide 1 comprises a fixable on a furniture body guide rail 2, on which a running rail 3 is movably mounted. To achieve a full extension can be arranged between the guide rail 2 and the running rail 3, at least one center rail 28. On the running rail 3, an activator 4 is set, which engages in a receptacle on a driver 5. The driver 5 is movably mounted on a track 6 with a bent end portion, wherein the raceway 6 is formed on a housing 7 which is fixedly connected to the guide rail 2. On the housing 7, a spring element 8 is attached.

Wie in den Figuren 2A und 2B zu sehen ist, ist in einem Federgehäuse 8 des Federelementes eine Stange 9 vorgesehen, die an einem kugelförmigen Endabschnitt 10 mit dem Mitnehmer 5 gekoppelt ist. Die Stange 9 ist an der gegenüberliegenden Seite mit einer Scheibe 11 versehen, an der ein Ende einer Druckfeder 12 abgestützt ist. Das gegenüberliegende Ende der Druckfeder 12 ist an einem Deckel 13 abgestützt, der an dem Federgehäuse 8 festgelegt ist. Das Federgehäuse 8 ist an einem Stutzen 14 des Gehäuses 7 rastend festlegbar.As in the FIGS. 2A and 2B can be seen, a rod 9 is provided in a spring housing 8 of the spring element, which is coupled to the driver 5 at a spherical end portion 10. The rod 9 is provided on the opposite side with a disc 11 to which one end of a compression spring 12 is supported. The opposite end of the compression spring 12 is supported on a cover 13 which is fixed to the spring housing 8. The spring housing 8 can be fixed in a latching manner on a socket 14 of the housing 7.

An dem Mitnehmer 5 ist fernen über ein Koppelelement 15 ein Mitnehmer 16 gehalten, der aus einem Draht mit einem gebogenen Endabschnitt 17 gebildet ist. Der Mitnehmer 16 greift in ein Bauteil 20 mit einer Steuerkurve ein, das über einen Be-Befestigungsabschnitt 19 an dem Gehäuse 7 festgelegt ist. Das Bauteil 20 ist dabei in eine Aufnahme 18 an dem Gehäuse 7 festgelegt, wobei der Mitnehmer 16 zwisehendem Bauteil 20 und der Aufnahme 18 bewegbar gelagert ist.At the driver 5, a driver 16 is held remotely via a coupling element 15, which is formed from a wire with a bent end portion 17. The driver 16 engages in a component 20 with a control cam, which has a Be-mounting portion 19 is fixed to the housing 7. The component 20 is fixed in a receptacle 18 on the housing 7, wherein the driver 16 zwisehendem member 20 and the receptacle 18 is movably mounted.

In Figur 3 ist eine modifizierte Ausführungsform eines Rastmechanismus an einer Auszugsführung 1 dargestellt, bei der ein kompaktes Gehäuse 7' vorgesehen ist, an dem ein Mitnehmer 5' geführt ist. Hierbei umfasst das Federelement ein Federgehäuse 8', an dessen Unterseite eine Aufnahme 18' ausgebildet ist, die mit dem Bauteil 20 gekoppelt ist. Zwischen dem Bauteil 20 und der Aufnahme 18' ist der Mitnehmer 16 bewegbar gelagert, der über einen Koppelelement 15 mit dem Mitnehmer 5' verfahrbar ist.In FIG. 3 a modified embodiment of a latching mechanism is shown on a pullout guide 1, in which a compact housing 7 'is provided, on which a driver 5' is guided. Here, the spring element comprises a spring housing 8 ', on the underside of a receptacle 18' is formed, which is coupled to the component 20. Between the member 20 and the receptacle 18 'of the driver 16 is movably mounted, which is movable via a coupling element 15 with the driver 5'.

Das Bauteil 20 bildet eine Steuerkurve 21 für den Mitnehmer 16 aus, wie dies in den Figuren 4A und 4B dargestellt ist. Die Steuerkurve 21 ist in einem Bereich schlaufenförmig ausgebildet und weist einen einspurigen Endabschnitt 23 in Öffnungsrichtung auf. Ferner ist an der Steuerkurve 21 eine muldenförmige Aufnahme 22 für den Mitnehmer 16 ausgebildet, in der der Mitnehmer 16 gegen die Kraft der Druckfeder 12 rastend festlegbar ist.The component 20 forms a control cam 21 for the driver 16, as shown in the FIGS. 4A and 4B is shown. The control cam 21 is loop-shaped in a region and has a single-track end portion 23 in the opening direction. Further, a trough-shaped receptacle 22 is formed on the control cam 21 for the driver 16, in which the driver 16 against the force of the compression spring 12 is latching fixed.

Wie aus den Figuren 5A und 5B ersichtlich ist, befindet sich benachbart zu der Aufnahme 22 eine Anlaufschräge 29, gegen die der Endabschnitt 17 des Mitnehmers 16 gedrückt wird, wenn der Rastmechanismus entriegelt werden soll. Dann bewegt sich der Mitnehmer 16 entlang der Anlaufschräge 29 in eine kanalförmige Auslaufzone 24 und bewegt sich dann durch die Kraft der Feder 12 in die Steuerkurve 21.Like from the FIGS. 5A and 5B it can be seen is located adjacent to the receptacle 22, a run-on slope 29 against which the end portion 17 of the driver 16 is pressed when the latching mechanism is to be unlocked. Then the driver 16 moves along the run-on slope 29 in a channel-shaped outlet zone 24 and then moves by the force of the spring 12 in the control cam 21st

In Figur 5A wird im Detail das Bauteil 20 kurz vor dem Verrasten des Mitnehmers 16 in der Schließposition gezeigt. Dann befindet sich der Endabschnitt 17 in einer zweiten Auslaufzone 25, die vor der Aufnahme 22 angeordnet ist. In Figur 5B ist im Detail dargestellt, dass an der Steuerkurve 21 eine federnde Rastklinke 27 angeordnet ist, deren freies Ende die Steuerkurve21 in Ruhelage bis an die Auslaufzone 25, die einen verbreiterten Endbereich besitzt, positioniert ist. Im Bereich der Rastklinke 27 wird der Mitnehmer 16 so weit seitlich verschoben, dass er bei einer Bewegung durch die Feder 12 in die Aufnahme 22 gleitet, und dort nach einem gewissen seitlichen Verschieben einrastet und nun gegenüber der Anlaufschräge 29 liegt.In FIG. 5A In detail, the component 20 is shown shortly before the engagement of the driver 16 in the closed position. Then, the end portion 17 is in a second outlet zone 25, which is arranged in front of the receptacle 22. In FIG. 5B is shown in detail that on the control cam 21, a resilient latch 27 is arranged, the free end of the cam 21 in rest position to the outlet zone 25, which has a widened end portion is positioned. In the region of the latch 27, the driver 16 is moved so far laterally that it slides in a movement by the spring 12 in the receptacle 22, and there after a certain lateral displacement snaps and now against the run-on slope 29 is located.

In Figur 6A ist im Detail ein Bereich der Steuerkurve 21 im Bereich der Aufnahme 22 gezeigt, wobei zwei längliche Auslaufzonen 25' und 24 in Form eines Kanals ausgebildet sind. Die Auslaufzone 25' ist länger als die Auslaufzone 24 ausgebildet und in einem Endabschnitt kann sich somit Schmutz 30 ansammeln, der durch Abrieb bei der Bewegung des Mitnehmers 16 entlang der Steuerkurve 21 oder durch andere Quellen entsteht.In FIG. 6A is shown in detail a portion of the control cam 21 in the region of the receptacle 22, wherein two elongated outlet zones 25 'and 24 are formed in the form of a channel. The run-off zone 25 'is formed longer than the run-off zone 24 and thus dirt 30 may accumulate in one end portion resulting from abrasion during movement of the follower 16 along the cam 21 or other sources.

In Figur 6B ist im Detail eine Auslaufzone 25 gezeigt, die sich verbreitert und somit eine Tasche ausbildet, in der sich Schmutz 30 ansammeln kann.In FIG. 6B In detail, an outlet zone 25 is shown, which widened and thus forms a pocket in which dirt 30 can accumulate.

In Figur 6C sind im Detail zwei voneinander beabstandete Auslaufzonen 25' und 24' gezeigt, die dieselbe Länge besitzen und insofern einen U-förmigen Endabschnitt der Steuerkurve 21 ausbilden, an dem die Anlaufschräge 29 mittig ausgebildet ist.In FIG. 6C are shown in detail two spaced outlet zones 25 'and 24', which have the same length and thus form a U-shaped end portion of the control cam 21, on which the run-on slope 29 is formed centrally.

In Figur 6D ist im Detail eine Ausführungsform von zwei Auslaufzonen 24" und 25" gezeigt, die miteinander verbunden sind, so dass sich in einem U-förmigen Endabschnitt Schmutz 30 ansammeln kann. Auch hier ist das Volumen der Auslaufzonen größer als für die Bewegungsbahn des Mitnehmers 16 erforderlich, damit in diesem Bereich Verunreinigungen abgelagert werden können. Ei-findungsgemäß wird der Verbindungsbereich nicht durch den Endabschnitt 17 durchfahren da sonst die Ruhelage nicht erreicht werden kann. Sollte der Verbindungsbereich dennoch durch den Endabschnitt 17 durchfahren werden, kann die Rastfunktion durch erneutes Drücken der Frontblende 41 eines Schubkastens in Schließrichtung wieder aktiviert werden.In FIG. 6D In detail, an embodiment of two run-off zones 24 "and 25" is shown, which are connected to one another, so that dirt 30 can accumulate in a U-shaped end section. Again, the volume of the outlet zones is greater than required for the trajectory of the driver 16 so that impurities can be deposited in this area. According to the invention, the connection area is not passed through the end section 17 since otherwise the rest position can not be reached. If the connection area is still passed through the end portion 17, the locking function can be reactivated by pressing the front panel 41 of a drawer in the closing direction again.

In Figur 7A bis 7D ist ein Möbel gezeigt, bei dem der erfindungsgemäße Rastmechanismus zum Einsatz kommt. Das Möbel umfasst einen Möbelkorpus 40, au dem mindestens eine Frontblende 41 für einen Schubkasten verfahrbar gelagert ist. An gegenüberliegenden Seiten des Möbelkorpus 40 kann entsprechend eine Auszugsführung 1 montiert sein.In FIGS. 7A to 7D a furniture is shown in which the locking mechanism according to the invention is used. The furniture comprises a furniture carcass 40, on which at least one front panel 41 is movably mounted for a drawer. On opposite sides of the furniture body 40 may be mounted according to a pullout guide 1.

Um den Schubkasten zu öffnen, wird die Frontblende 41 eines Schubkastens in Schließrichtung gegen den Möbelkorpus 40 gedrückt. Dabei kann durch eine seitliche Belastung eine Position entsprechend Figur 7B erreicht werden, an der die Frontblende 41 an einer Seite schon am Möbelkorpus 40 anliegt und sich auf der gegenüberliegenden Seite noch ein Abstand L zwischen Möbelkorpus 40 und Frontblende 41 ergibt (Figur 7C).To open the drawer, the front panel 41 of a drawer is pressed in the closing direction against the furniture body 40. It can by a lateral load a position accordingly FIG. 7B can be achieved at the front panel 41 already rests on one side on the furniture body 40 and on the opposite side still a distance L between the furniture body 40 and front panel 41 results ( FIG. 7C ).

Im Bereich des Bauteils 20 und der Steuerkurve 21 sieht dann die Position des Mitnehmers 16 so aus, dass entsprechend Figur 8A auf der linken Seite, also dort, wo ein Abstand L zwischen Möbelkorpus 40 und Frontblende 41 vorhanden ist, der Mitnehmer 16 nur geringfügig aus der Aufnahme 22 herausbewegt wurde und durch Anliegen an der Anlaufschräge 29 seitlich verschoben wurde, aber allenfalls geringfügig in die Auslaufzone 24 hineinbewegt wird. An der gegenüberliegenden rechten Seite ist der Mitnehmer 16 hingegen weitgehend in die Auslaufzone 24 hineinbewegt worden, da dort die Fronblende 41 an dem Möbelkorpus 40 anliegt. Diese ungleiche Bewegung der Frontblende 41 relativ zu dem Möbelkorpus 40 ist zur Entriegelung der beiden Rastmechanismen jedoch unschädlich, da zumindest an beiden Seiten eine Bewegung des jeweiligen Mitnehmers 16 soweit erreicht wurde, dass dieser aus der jeweiligen Aufnahme 22 bewegt wurde.In the area of the component 20 and the control cam 21, the position of the driver 16 then looks like that accordingly Figure 8A on the left side, so where a distance L between the furniture body 40 and front panel 41 is present, the driver 16 was moved only slightly out of the receptacle 22 and was laterally displaced by concerns on the run-on slope 29, but at most slightly in the outlet zone 24th is moved in. On the opposite right side of the driver 16, however, has been largely moved into the outlet zone 24, since there the bezel 41 rests against the furniture body 40. However, this uneven movement of the front panel 41 relative to the furniture body 40 is harmless for unlocking the two locking mechanisms, since at least on both sides a movement of the respective driver 16 has been reached so far that it has been moved from the respective receptacle 22.

In den Figuren 9A bis 9D ist ein Möbelkorpus 40 mit einer Frontblende 41 während des Schließvorganges gezeigt. Auch hier ist beispielhaft an der linken Seite des Möbelkorpus 40 ein Abstand L zwischen Möbelkorpus 40 und Frontblende 41 vorhanden. Dies wirkt sich auf den Rastmechanismus, so aus, wie dies in den Figuren 10A und 10B dargestellt ist. Auf der rechten Seite liegt die Frontblende 41 an dem Möbelkorpus 40 an, so dass entsprechend Figur 10B der Mitnehmer 16 nahezu vollständig in die Auslaufzone 25' hineinbewegt wurde und somit ein sicheres Verrasten im nächsten Schritt gewährleistet ist.In the FIGS. 9A to 9D a furniture body 40 is shown with a front panel 41 during the closing process. Here too, by way of example, a distance L between the furniture carcass 40 and the front panel 41 is provided on the left side of the furniture carcass 40. This affects the latching mechanism, as it does in the Figures 10A and 10B is shown. On the right side, the front panel 41 rests against the furniture body 40, so that accordingly FIG. 10B the driver 16 was almost completely moved into the outlet zone 25 'and thus secure locking in the next step is ensured.

Auf der gegenüberliegenden linken Seite ist entsprechend Figur 10A und 9C ein Abstand L zwischen Frontblende 41 und Möbelkorpus 40 vorhanden. Der Mitnehmer 16 wurde allerdings so weit durch die Steuerkurve 21 bewegt, dass die Rastklinke 27 durchlaufen wurde und somit der Mitnehmer 16 vor der Auslaufzone 25' angeordnet ist, Wird nun die Frontblende 41 losgelassen, gleitet sowohl der Mitnehmer 16 auf der linken Seite als auch der Mitnehmer 16 auf der rechten Seite in die jeweils für ihn vorgesehene Aufnahme 22 an dem Bauteil 20.On the opposite left side is corresponding FIGS. 10A and 9C a distance L between the front panel 41 and furniture body 40 is present. However, the driver 16 has been moved so far by the control cam 21 that the latch 27 has been passed through and thus the driver 16 in front of the outlet zone 25 ' If the front panel 41 is now released, both the driver 16 on the left side and the driver 16 on the right side slide into the respective receptacle 22 provided on the component 20.

In den vorangegangenen Ausführungsbeispielen wurde der Rastmechanismus für eine Auszugsführung beschrieben. Es ist natürlich auch möglich, einen solchen Rastmechanismus bei Türen, Klappen oder anderen verschwenkbaren Bauteilen vorzusehen. Zudem kann die Art des Rastmechanismus mit einem Federelement und anderen Bauteilen anders als beschrieben ausgebildet sein.In the foregoing embodiments, the detent mechanism for a pullout guide has been described. Of course, it is also possible to provide such a latching mechanism in doors, flaps or other pivotable components. In addition, the nature of the latching mechanism may be formed differently with a spring element and other components as described.
