Description

Die vorliegende Erfindung betrifft eine Öffnungsvorrichtung für eine Ausziehführung, insbesondere für Schubkästen, mit einem Führungsgehäuse, an dem eine Rastklinke entlang einer Führung verschiebbar ist, wobei die Rastklinke entlang der Führung in zwei beabstandeten Positionen fixierbar ist und eine Aufnahme für einen Aktivator aufweist, der mit einer bewegbaren Schiene der Ausziehführung koppelbar ist, und ein Rastmechanismus vorgesehen ist, um die Rastklinke in einer Schließposition gegen die Kraft einer Feder zu fixieren, sowie einen Rastmechanismus.The present invention relates to an opening device for a pull-out, in particular for drawers, with a guide housing on which a latch is slidable along a guide, wherein the latch is fixed along the guide in two spaced positions and has a receptacle for an activator with a movable rail of the pull-out guide is coupled, and a latching mechanism is provided to fix the latch in a closed position against the force of a spring, and a latching mechanism.

Eine Ausziehführung wird aus einer am Möbelkorpus festgelegten Führungsschiene und einer am Auszugselement festgelegten Laufschiene, sowie gegebenenfalls einer auszugsverlängernden Mittelschiene gebildet.A pull-out guide is formed from a guide rail fixed to the furniture body and a running rail fixed to the pull-out element, as well as, if appropriate, an extension-extending center rail.

Die EP 766939 offenbart eine Öffnungs- und Schließvorrichtung für eine Schublade, bei der rückseitig an der Schublade ein Hebel angeordnet ist, der an einem Rastmechanismus fixiert werden kann. Hierfür wird der Hebel entlang einer Steuerkurve gegen den Druck einer Feder verfahren. Die Feder und die Steuerkurve sind dabei beabstandet voneinander angeordnet und die Feder kontaktiert im Eingriffsfall endseitig die Schublade. Dadurch müssen Steuerkurve und Feder aufeinander abgestimmt sein, insbesondere auch im Hinblick auf die Lage und Anordnung einer Schublade im Möbelkorpus. Zudem ist der Platzbedarf des Rastmechanismus vergleichsweise groß.The EP 766939 discloses an opening and closing device for a drawer, in which the back of the drawer, a lever is arranged, which can be fixed to a latching mechanism. For this purpose, the lever is moved along a control cam against the pressure of a spring. The spring and the control cam are spaced apart from each other and contacted the spring in the event of engagement end of the drawer. As a result, control cam and spring to each other Be tuned, especially with regard to the location and arrangement of a drawer in the furniture body. In addition, the space requirement of the locking mechanism is comparatively large.

In der EP 743032 ist eine Weiterentwicklung des Rastmechanismus für eine Schubkastenauszugsführung gezeigt, bei dem ein mit einem Schubkasten gekoppelter Aktivator mit einer Rastklinke verbindbar ist. Die Rastklinke ist dabei an einer Führungsbahn eines Gehäuses geführt und kann in einer Schließposition des Schubkastens gegen die Kraft einer Feder verrastet werden. Dadurch wird bei einer Entriegelung der Rastklinke der Schubkasten in Öffnungsrichtung bewegt. Die Führung der Rastklinke entlang der Führungsbahn an dem Gehäuse führt gerade bei ruck- oder stoßartigen Bewegungen zu erheblichen Materialbelastungen. Dies begrenzt die Lebensdauer, wobei die dauerhafte Zugbelastung der Feder zu Ermüdungserscheinungen führen kann. Das offene Gehäuse kann zudem durch Verschmutzungen die Führung der Rastklinke beeinträchtigen.In the EP 743032 a further development of the locking mechanism for a drawer slide is shown, in which a coupled with a drawer activator with a latch is connectable. The latch is guided on a guideway of a housing and can be locked in a closed position of the drawer against the force of a spring. As a result, the drawer is moved in the opening direction in an unlocking of the latch. The guidance of the latch along the guideway to the housing leads just in jerky or jerky movements to considerable material loads. This limits the life, whereby the permanent tensile load of the spring can lead to fatigue. The open housing can also affect the contamination of the leadership of the latch.

Die EP 1845821 offenbart eine Öffnungs- und Schließvorrichtung für Ausziehfiihrungen, bei der ein Mitnehmer an einer Laufschiene mit einem Klinkenbauteil gekoppelt ist, das entlang eines Klinkengehäuses geführt ist. Das Klinkenbauteil ist mit einem Rastmechanismus gekoppelt, der das Klinkenbauteil bistabil in zwei beabstandeten Positionen verrasten kann. Das Klinkengehäuse weist hierfür eine Führungsbahn an einem Gehäuse auf, in der ein Stift einer Koppelstange geführt ist. Die Koppelstange ist dabei durch eine Feder vorgespannt und an einem Ende mit dem Klinkenbauteil gekoppelt. Auch hier führt die Führung der Koppelstange entlang einer Steuerkurve dazu, dass die Materialbelastungen beim Verschwenken erheblich sind. Gerade bei stoßhaften Belastungen kann es hier zu Beschädigungen und Fehlfunktionen kommen. Zudem ist die Lebensdauer eines solchen Rastmechanismusses begrenzt.The EP 1845821 discloses an opening and closing device for Ausziehfiihrungen, in which a driver is coupled to a running rail with a pawl member, which is guided along a pawl housing. The latch member is coupled to a detent mechanism that can latch the latch member in two spaced apart positions. For this purpose, the pawl housing has a guide track on a housing in which a pin of a coupling rod is guided. The coupling rod is biased by a spring and coupled at one end to the latch member. Again, the leadership of the coupling rod along a cam to the fact that the material loads during pivoting are significant. Especially with shock loads, damage and malfunctions can occur here. In addition, the life of such a Rastmechanismusses is limited.

Es ist daher Aufgabe der vorliegenden Erfindung, eine Öffnungsvorrichtung für eine Ausziehführung zu schaffen, die bei einfachem und kompaktem Aufbau nur einen geringen Materialverschleiß besitzt.It is therefore an object of the present invention to provide an opening device for a pull-out, which has a low material wear in a simple and compact design.

Diese Aufgabe wird mit einer Öffnungsvorrichtung für eine Ausziehführung mit den Merkmalen des Anspruches 1 und einem Rastmechanismus mit den Merkmalen des Anspruches 6 gelöst.This object is achieved with an opening device for a pull-out guide with the features of claim 1 and a latching mechanism with the features of claim 6.

Der Rastmechanismus weist ein im Wesentlichen zylinderförmiges Gehäuse mit einer Steuerkurve auf, entlang der ein Steuerelement in eine Längsrichtung des Gehäuses verschiebbar und erfindungsgemäß um eine Längsachse drehbar geführt ist. Dadurch kann das Steuerelement in dem Gehäuse entlang der Steuerkurve gleiten, wobei nur geringe Materialbelastungen vorhanden sind. Denn die Steuerkurve kann das Steuerelement leichtgängig führen, da dieses flexibel sowohl verschiebbar als auch drehbar ist, so dass keine Biegebelastungen oder größere Reibungskräfte auftreten können. Zudem ist das Steuerelement in dem Gehäuse geschützt angeordnet, so dass auch Verschmutzungen die Funktion des Rastmechanismuses nicht beeinträchtigen können.The latching mechanism has a substantially cylindrical housing with a control cam, along which a control element is displaceably guided in a longitudinal direction of the housing and according to the invention rotatable about a longitudinal axis. This allows the control slide in the housing along the control cam, with only low material loads are present. Because the cam can guide the control smoothly, since this is both flexible and rotatable, so that no bending loads or greater frictional forces can occur. In addition, the control is arranged protected in the housing, so that even dirt can not affect the function of the locking mechanism.

Gemäß einer bevorzugten Ausgestaltung der Erfindung ist durch das Steuerelement eine Stange bewegbar, die endseitig mit der Rastklinke gekoppelt ist, Dadurch kann auf die Rastklinke eine im Wesentlichen lineare Bewegung übertragen werden, wobei die Stange nahezu abgedichtet in das Gehäuse des Rastmechanismus geführt sein kann, so dass dieser besonders geschützt angeordnet ist. Zudem kann die Mechanik der Rastklinke und die Mechanik des Rastmechanismuses beabstandet voneinander vorgesehen sein, so dass die Öffnungsvorrichtung auch bei beengtem Bauraum in einem Möbelkorpus montierbar ist.According to a preferred embodiment of the invention, a rod is movable by the control, which is coupled at the end with the detent pawl, Thus, a substantially linear movement can be transmitted to the latch, wherein the rod can be performed nearly sealed in the housing of the latching mechanism, so that this is particularly protected. In addition, the mechanism of the latch and the mechanism of the latching mechanism can be provided spaced apart from each other, so that the opening device can be mounted in a furniture carcass even in confined space.

Für eine gute Führung des Steuerelementes kann dieses ringförmig ausgebildet sein. Dadurch kann das Steuerelement an seiner äußeren Umfangsfläche geführt sein, wobei mindestens ein radial hervorstehender Vorsprung vorgesehen sein kann, der dann in die Steuerkurve eingreift. Es können auch zwei oder mehr Vorsprünge ausgebildet sein, wobei mehrere Anlageflächen der Steuerkurve für eine Führung des Steuerelementes sorgen können.For a good guidance of the control this may be annular. Thereby, the control may be guided on its outer peripheral surface, wherein at least one radially projecting projection may be provided, which then engages in the control cam. It can also be formed two or more projections, wherein a plurality of contact surfaces of the control cam can provide a guide of the control.

Für die Möglichkeit einer effektiven Herstellung des Gehäuses mit einer Steuerkurve kann dieses mehrteilig ausgebildet sein, wobei ein zylinderförmiges Gehäuseteil vorgesehen ist, an das mindestens ein äußeres Gehäuseteil zur Ausbildung der Steuerkurve zumindest teilweise eingesteckt ist. Die Steuerkurve kann dabei durch einen Randabschnitt gebildet sein, der an dem eingesteckten Teil des äußeren Gehäuseteils ausgebildet ist. Der eingesteckte Abschnitt kann dabei hülsenförmig in das zylinderförmige Gehäuseteil eingeschoben sein, wobei der Randabschnitt dann mit einem Vorsprung oder mehreren Vorsprüngen an dem Steuerelement zusammenwirkt.For the possibility of effective production of the housing with a control cam, this can be designed in several parts, wherein a cylindrical housing part is provided, to the at least one outer housing part for training the control cam is at least partially inserted. The control cam can be formed by an edge portion which is formed on the inserted part of the outer housing part. The inserted portion may be inserted sleeve-shaped in the cylindrical housing part, wherein the edge portion then cooperates with a projection or a plurality of projections on the control.

Vorzugsweise ist an jeder Seite des zylinderförmigen Gehäuseteils ein äußeres Gehäuseteil zumindest teilweise eingesteckt. Dadurch können die gegenüberliegenden Gehäuseteile eine an gegenüberliegenden Seiten eine ganz oder teilweise geschlossene Steuerkurve bilden.Preferably, an outer housing part is at least partially inserted on each side of the cylindrical housing part. As a result, the opposite housing parts can form a completely or partially closed control cam on opposite sides.

In einer weiteren Ausgestaltung der Erfindung ist an dem mindestens einen äußeren Gehäuseteil eine benachbart zur inneren Wand des zylinderförmigen Gehäuseteils angeordnete Steuerkurve vorgesehen, die mit dem mindestens einen Vorsprung des Steuerelementes zusammenwirkt. Die Steuerkurve kann dünnwandig ausgebildet sein und an dem zylinderförmigen äußeren Gehäuseteil abgestützt sein, so dass eine sichere Führung des Steuerelementes gewährleistet ist.In a further embodiment of the invention, a control cam arranged adjacent to the inner wall of the cylindrical housing part is provided on the at least one outer housing part, which cam cooperates with the at least one projection of the control element. The cam can be formed thin-walled and be supported on the cylindrical outer housing part, so that a secure guidance of the control is ensured.

Für eine effektive Montage kann das mindestens eine äußere Gehäuseteil mit dem zylinderförmigen Gehäuseteil verrastet sein.For an effective assembly, the at least one outer housing part can be locked to the cylindrical housing part.

In einer bevorzugten Ausgestaltung der Erfindung ist in dem Gehäuse ein Kraftspeicher zum Vorspannen der Rastklinke vorgesehen. Der Kraftspeicher kann dabei als Druckfeder endseitig an einem äußeren Gehäuseteil abgestützt sein.In a preferred embodiment of the invention, an energy accumulator for biasing the latch is provided in the housing. The energy accumulator can be supported as a compression spring end to an outer housing part.

Vorzugsweise ist die Schließposition der Rastklinke über den Rastmechanismus verstellbar. Dadurch kann entsprechend auch die Schließposition der Frontblende eines Schubkastens verstellt werden, beispielsweise für eine bündige Ausrichtung. Somit ist eine Justierung des Auslöseweges zur Gewährleistung der Funktion möglich. Aufgrund der Fertigungsgegebenheiten im Möbelbau werden große Toleranzen akzeptiert, um eine hohe Betriebssicherheit der Öffnungsvorrichtung zu erreichen kann diese verstellbar ausgeführt werden. Denn die Frontblende eines Schubkastens ist über die Ausziehführung, den Aktivator und die Rastklinke mit dem Rastmechanismus gekoppelt, so dass Montagetoleranzen über den Rastmechanismus ausgeglichen werden können. Zum Verstellen der Schließposition kann zumindest ein Gehäuseteil, das einen Teil der Steuerkurve mit einer Rastaufnahme ausbildet, relativ zu dem Führungsgehäuse der Rastklinke verstellbar sein. Denn für das Verstellen der Rastklinke reicht es aus, wenn die entsprechende Rastaufnahme des Rastmechanismus relativ zu dem Führungsgehäuse verstellt wird. Eine stufenlose Verstellung wird beispielsweise dann ermöglicht, wenn ein äußeres Gehäuseteil über ein Gewinde in Längsrichtung verstellbar ist.Preferably, the closed position of the latch is adjustable via the latching mechanism. As a result, the closed position of the front panel of a drawer can be adjusted accordingly, for example, for a flush alignment. Thus, an adjustment of the trip path to ensure the function is possible. Due to the manufacturing conditions in furniture large tolerances are accepted in order to achieve high reliability of the opening device can be made adjustable. Because the front panel of a drawer is on the pull-out, the activator and the latch with the Locking mechanism coupled so that mounting tolerances on the locking mechanism can be compensated. To adjust the closing position, at least one housing part, which forms a part of the control cam with a latching receptacle, can be adjusted relative to the guide housing of the latching pawl. Because for the adjustment of the latch, it is sufficient if the corresponding locking receptacle of the locking mechanism is adjusted relative to the guide housing. A stepless adjustment is made possible, for example, when an outer housing part is adjustable via a thread in the longitudinal direction.

Für eine kompakte Ausbildung des Rastmechanismuses kann der Kraftspeicher als Druckfeder ausgebildet sein, die auf die Rastklinke über die in dem Gehäuse angeordnete Stange wirkt. Die Druckfeder kann dabei an einer Scheibe abgestützt sein, die mit der Stange gekoppelt ist, so dass die Stange linear innerhalb des Gehäuses geführt ist. Aufgrund des geringeren Durchmessers gegenüber dem Steuerelement mit den radial hervorstehenden Vorsprüngen wirkt die Steuerkurve nicht auf die Scheibe. Dadurch ist der Kraftspeicher weitgehend vor äußeren Umgebungseinflüssen geschützt.For a compact design of the latching mechanism, the energy accumulator can be designed as a compression spring which acts on the latching pawl via the rod arranged in the housing. The compression spring can be supported on a disc which is coupled to the rod, so that the rod is guided linearly within the housing. Due to the smaller diameter relative to the control with the radially protruding projections, the control cam does not act on the disc. As a result, the energy storage is largely protected from external environmental influences.

Die Öffnungsvorrichtung muss nicht um eine Zuhaltevorrichtung ergänzt werden, was eine Kostenersparnis und eine sehr kompakte Bauweise ermöglicht. Aus dem Stand der Technik bekannte Öffnungsvorrichtung müssen um einen Zuhaltemechanismus über eine Zugfeder ergänzt werden um ein ungewolltes Öffnen des Schubkastens zu vermeiden. Die Zuhaltung erfolgt über einen Vorsprung am Steuerelement, der in der geschlossenen Position in einer Rastaufnahme der Steuerkurve festgelegt wird.The opening device does not have to be supplemented by a locking device, which allows cost savings and a very compact design. Known from the prior art opening device must be supplemented by a locking mechanism via a tension spring to prevent accidental opening of the drawer. The tumbler is via a projection on the control element, which is fixed in the closed position in a locking receptacle of the control cam.

Ein Endanschlag wird über einen Einschubanschlag an der Rastklinke und einem Einschubanschlag an dem Führungsgehäuse gebildet. Unabhängig davon, kann durch die Justiervorrichtung der Abstand der Frontblende gegenüber dem Möbelkorpus eingestellt werden um die Funktion der Öffnungsvorrichtung zu gewährleisten.An end stop is formed via a slot stop on the latch and a slot stop on the guide housing. Regardless, the distance of the front panel relative to the furniture body can be adjusted by the adjusting device to ensure the function of the opening device.

Das Gehäuse der Öffnungsvorrichtung kann auch einteilig, z.B. mit einem Filmscharnier, ausgeführt sein. Zum anderen ist es denkbar mit einem verlorenen Einschub, wie z.B. einem Wachskern, zu arbeiten. Es ist ebenfalls denkbar das Gehäuse aus zwei Hälften zu produzieren. Auch andere Herstellverfahren können eingesetzt werden.The housing of the opening device can also be made in one piece, for example with a film hinge. On the other hand, it is conceivable with a lost slot, like a waxy kernel, to work. It is also conceivable to produce the housing from two halves. Other manufacturing methods can be used.

Der erfindungsgemäße Rastmechanismus wird vorzugsweise für Öffnungsvorrichtungen für Auszugsführungen eingesetzt, kann aber auch für andere bewegbare Möbelteile, wie Klappen oder Schiebetüren verwendet werden. Dabei kann der Rastmechanismus auch einen bewegbaren Anschlag aufweisen, der nicht fest mit einer Rastklinke oder dem bewegbaren Möbelteil verbunden ist. Der Anschlag ist bevorzugt endständig an der Stange des Rastmechanismus angeordnet. Der Rastmechanismus kann über den bewegbaren Anschlag ein bewegliches Möbelteil aus einer ersten in eine zweite Position bewegen. Bevorzugt dient der Rastmechanismus zum Ausstoßen von beweglichen Möbelteilen. Zum möglichen Einsatzgebiet zählen z.B. auch Haushaltsgeräte wie Backöfen oder Kühlgeräte.The locking mechanism according to the invention is preferably used for opening devices for drawer guides, but can also be used for other movable furniture parts, such as flaps or sliding doors. In this case, the latching mechanism may also have a movable stop, which is not fixedly connected to a latch or the movable furniture part. The stop is preferably arranged terminally on the rod of the latching mechanism. The latching mechanism can move a movable furniture part from a first to a second position via the movable stop. Preferably, the locking mechanism is used for ejecting movable furniture parts. Possible applications include e.g. also household appliances such as ovens or refrigerators.

Ein Schubkasten 1 ist über eine Ausziehführung 2 verschiebbar an einem Möbelkorpus gelagert, wobei hierfür eine Führungsschiene 3 an einem Möbelkorpus (nicht gezeigt) festgelegt ist. An der Führungsschiene 3 ist eine Laufschiene 4 über Wälzkörper verschiebbar gehalten, auf der ein Boden 5 des Schubkastens 1 abgestützt ist.A drawer 1 is mounted on a pull-out guide 2 slidably mounted on a furniture body, for which purpose a guide rail 3 is fixed to a furniture body (not shown). On the guide rail 3, a running rail 4 is slidably held by rolling elements, on which a bottom 5 of the drawer 1 is supported.

An der Führungsschiene 3 ist ein flaches Führungsgehäuse 6 vorgesehen, an dem eine Führung 8 in Form einer kulissenförmigen Aussparung ausgebildet ist. In der Führung 8 ist eine Rastklinke 7 verschiebbar geführt. An der Rastklinke 7 ist eine Aufnahme 90 vorgesehen, die mit einem Aktivator 9 (Mitnehmer) koppelbar ist, der an der Laufschiene 4 festgelegt ist.On the guide rail 3, a flat guide housing 6 is provided, on which a guide 8 is formed in the form of a backdrop-shaped recess. In the guide 8 a latch 7 is guided displaceably. At the latch 7, a receptacle 90 is provided which can be coupled with an activator 9 (driver), which is fixed to the running rail 4.

Die in Figur 2 dargestellte Öffnungsvorrichtung ist an einer Ausziehführung dargestellt, die zur Lagerung von Schubkästen dient, aber auch für andere verschiebbare Elemente, wie Ablagen, Schiebehalter oder dergleichen einsetzbar ist.In the FIG. 2 illustrated opening device is shown on a pull-out, which serves for the storage of drawers, but also for other movable elements, such as shelves, sliding holder or the like can be used.

Die Öffnungsvorrichtung umfasst zudem ein Gehäuse 11, das einen Rastmechanismus aufweist, um die Rastklinke 7 in zwei voneinander beabstandeten Positionen zu fixieren. Eine dieser Positionen ist die Schließposition, bei der die Rastklinke 7 gegen die Kraft einer Feder verrastet ist. Die Rastklinke 7 ist dabei über eine Stange 10 mit dem Rastmechanismus in dem Gehäuse 11 gekoppelt.The opening device also includes a housing 11 having a latching mechanism to fix the latch 7 in two spaced-apart positions. One of these positions is the closed position in which the detent pawl 7 is locked against the force of a spring. The latch 7 is coupled via a rod 10 with the latching mechanism in the housing 11.

Die Begriffe "öffnen" und "schließen" beziehen sich auf eine Endstellung des Schubkastens 1 in einem Möbelkorpus, in dem der Schubkasten eingefahren ist und entsprechend geöffnet oder geschlossen werden kann. Die "Schließlage" kann jedoch auch eine andere Lage sein, bei der das zu fixierende Bauteil über den Rastmechanismus gehalten ist.The terms "open" and "close" refer to an end position of the drawer 1 in a furniture body in which the drawer is retracted and can be opened or closed accordingly. However, the "closed position" may also be another position in which the component to be fixed is held by the latching mechanism.

In Figur 3 ist die Rastklinke 7 ohne den Aktivator 9 dargestellt, der in eine Aufnahme 90 an der Rastklinke 7 eingreift, die durch zwei beabstandete Vorsprünge 91 und 92 gebildet ist. Die Führung 8 an dem Führungsgehäuse 6 weist an einem Ende einen abgebogenen Abschnitt 80 auf, an dem die Rastklinke 7 verschwenkt wird, um den Aktivator 9 freizugeben. Aus dieser Position kann die Laufschiene 4 in eine vollständig ausgefahrene Position bewegt werden. Die Rastklinke 7 ist ferner über einen Rastmechanismus in einer Schließposition der Ausziehführung beziehungsweise des Schubkastens 1 verrastbar.In FIG. 3 the latch 7 is shown without the activator 9, which engages in a receptacle 90 on the latch 7, which is formed by two spaced-apart projections 91 and 92. The guide 8 on the guide housing 6 has at one end a bent portion 80, on which the latch 7 is pivoted to release the activator 9. From this position, the running rail 4 can be moved to a fully extended position. The latch 7 is further locked by a latching mechanism in a closed position of the pull-out or the drawer 1.

In Figur 4 sind die Bauteile des Gehäuses 11 und des Rastmechanismuses gezeigt. Das Gehäuse 11 umfasst ein hülsenförmiges mittleres Gehäuseteil 12, an das ein äußeres Gehäuseteil 13 aufgesteckt ist. Hierbei greift ein hülsenförmiger Abschnitt 14 mit geringerem Außendurchmesser in das hülsenförmige Gehäuse 12 ein. An dem Abschnitt 14 ist endseitig ein Rand 15' ausgebildet, der Teil einer Steuerkurve bildet. Das äußere Gehäuseteil 13 weist an dem Abschnitt 14 ferner Vorsprünge 16 auf, die in entsprechende Aussparungen 17 an dem hülsenförmigen Gehäuse 12 eingerastet sind.In FIG. 4 the components of the housing 11 and the latching mechanism are shown. The housing 11 comprises a sleeve-shaped middle housing part 12, to which an outer housing part 13 is attached. Here, a sleeve-shaped portion 14 engages with a smaller outer diameter in the sleeve-shaped housing 12 a. At the portion 14, an edge 15 'is formed at the end, which forms part of a control cam. The outer housing part 13 has at the portion 14 further projections 16 which are engaged in corresponding recesses 17 on the sleeve-shaped housing 12.

An der gegenüberliegenden Seite des hülsenförmigen Gehäuseteils 12 ist ein zweites äußeres Gehäuseteil 20 vorgesehen, das ebenfalls einen Abschnitt 21 mit reduziertem Außendurchmesser aufweist, der in das hülsenförmige Gehäuseteil 12 eingesteckt ist. An dem Abschnitt 21 ist ein Rand 22 vorgesehen, der ebenfalls Teil einer Steuerkurve bildet. An dem Abschnitt 21 sind ferner Vorsprünge 23 ausgebildet, mittels derer das Gehäuseteil 20 an dem hülsenförmigen Gehäuseteil 12 verrastet werden kann. Hierfür sind entsprechende Aussparungen 18 vorgesehen. Eine innere Umfangswand 19 des hülsenförmigen Gehäuseteils 12 umgibt dabei die Abschnitte 14 und 21 der äußeren Gehäuseteile 13 und 20. Der äußere Gehäuseteil 20 weist Rastausnehmungen 24 zur Festlegung des Gehäuses 11 am Führungsgehäuse 6 auf. Die Rastausnehmungen 24 dienen zum Festlegen des Gehäuses 11 an dem Führungsgehäuse 6 mittels Rastnasen 25. Es ist auch eine kraft-, form- und / oder stoffschlüssige Festlegung des Gehäuses 11 an dem Führungsgehäuse 6 denkbar.On the opposite side of the sleeve-shaped housing part 12, a second outer housing part 20 is provided, which also has a portion 21 with a reduced outer diameter, which is inserted into the sleeve-shaped housing part 12. At the portion 21, an edge 22 is provided, which also forms part of a control cam. At the portion 21 projections 23 are further formed, by means of which the housing part 20 can be latched to the sleeve-shaped housing part 12. For this purpose, corresponding recesses 18 are provided. An inner peripheral wall 19 of the sleeve-shaped housing part 12 surrounds the sections 14 and 21 of the outer housing parts 13 and 20. The outer housing part 20 has latching recesses 24 for fixing the housing 11 to the guide housing 6. The locking recesses 24 are used to set the housing 11 to the guide housing 6 by means of locking lugs 25. It is also a force, positive and / or cohesive fixing of the housing 11 to the guide housing 6 conceivable.

Ferner ist eine Stange 10 in dem Gehäuse 11 vorgesehen, die endseitig einen kugelförmigen Abschnitt 26 aufweist, der mit der Rastklinke 7 verrastet ist. An der gegenüberliegenden Seite ist an der Stange 10 eine Scheibe 27 konzentrisch festgelegt, die zur endseitigen Abstützung einer Feder 28 dient. Ferner ist auf der zur Feder 28 gegenüberliegenden Seite der Scheibe 27 ein ringförmiges Steuerelement 30 auf die Stange 10 aufgeschoben, das zwei radial gegenüberliegende nach außen hervorstehende Vorsprünge 31 umfasst. Das Steuerelement 30 ist dabei in dem Gehäuse 12 und um die Stange 10 drehbar angeordnet. Somit ist eine gleichmäßige Kraftverteilung innerhalb der Öffnungsvorrichtung gewährleistet, ein Verkanten oder Verklemmen der Öffnungsvorrichtung wird somit vermieden.Further, a rod 10 is provided in the housing 11, the end has a spherical portion 26 which is latched to the latch 7. On the opposite side, a disc 27 is concentrically fixed to the rod 10, which serves for the end-side support of a spring 28. Further, on the opposite side of the disc 27 to the spring 27, an annular control member 30 is pushed onto the rod 10, which comprises two radially outwardly projecting projections 31. The control element 30 is in the housing 12 and rotatably disposed about the rod 10. Thus, a uniform force distribution is ensured within the opening device, tilting or jamming of the opening device is thus avoided.

In Figur 5 ist das mittlere hülsenförmige Gehäuseteil 12 gezeigt, in dem zwei jeweils erhaben von der Innenwandung angeordnete Bereiche der diametral gegenüberliegenden Steuerkurven 33 gezeigt sind, die in Ihren Abschnitten 15 und 22 mit den Abschnitten 15' und 22' der Gehäuseteile 13 und 20 korrespondieren und damit eine umlaufende nutartige Steuerkurve 33 ausbilden. Die dargestellte Steuerkurve 33 entspricht der Bewegungsbahn der Vorsprünge 31an dem Steuerelement 30 beim Öffnen und Schließen des Schubkastens 1.In FIG. 5 the middle sleeve-shaped housing part 12 is shown, in which two each of the inner wall arranged regions of the diametrically opposed control cams 33 are shown, which correspond in their sections 15 and 22 with the sections 15 'and 22' of the housing parts 13 and 20 and thus a form circumferential groove-like cam 33. The illustrated cam 33 corresponds to the path of movement of the projections 31 on the control element 30 during opening and closing of the drawer 1.

Die Figur 6 zeigt den Zusammenbau durchsichtig dargestellt. Somit sind die umlaufenden nutartigen Steuerkurven 33 erkennbar.The FIG. 6 shows the assembly shown transparently. Thus, the circumferential groove-like cam 33 can be seen.

Einen Endabschnitt der Stange 10 mit dem Steuerelement 30 gibt die Figur 7 wieder. In der Figur 8 sowie in der Figur 11 sind die beiden radialen Vorsprünge 31 an dem Steuerelement 30 erkennbar. Die Schnittzeichnung Figur 9 gibt den Blick auf die Wulst 37 an der Stange 10 sowie die Nut 38 im Steuerelement 30 zur drehbaren Lagerung und Längsfixierung des Steuerelementes 30 frei.An end portion of the rod 10 with the control 30 is the FIG. 7 again. In the FIG. 8 as well as in the FIG. 11 are the two radial projections 31 on the control 30 recognizable. The sectional drawing FIG. 9 gives the view of the bead 37 on the rod 10 and the groove 38 in the control member 30 for rotatable mounting and longitudinal fixation of the control 30 free.

Eine alternative Ausführung des Endabschnittes der Stange 10 mit dem Steuerelement 30' gibt die Figur 10 wieder. Hier wird eine in eine Nut 44 eingeschnappte Federscheibe 39 zur drehbaren Lagerung und Längsfixierung des Steuerelementes 30' dargestellt. Die Schnittzeichnung Figur 12 gibt den Blick auf die Federscheibe 39 sowie die Nut 44 in der Stange 10 zur drehbaren Lagerung und Längsfixierung des Steuerelementes 30' frei.An alternative embodiment of the end portion of the rod 10 with the control 30 'is the FIG. 10 again. Here, a snapped into a groove 44 spring washer 39 for rotatable mounting and longitudinal fixation of the control 30 'is shown. The sectional drawing FIG. 12 gives the view of the spring washer 39 and the groove 44 in the rod 10 for rotatable mounting and longitudinal fixation of the control element 30 'free.

Die Funktion des Rastmechanismusses wird nachfolgend mit Bezug auf die Figuren 13A bis 13F näher erläutert.The function of the latching mechanism will be described below with reference to FIGS FIGS. 13A to 13F explained in more detail.

In Figur 13A ist die Rastposition in Schließlage gezeigt, in der der Rastmechanismus das Steuerelement 30 gegen die Kraft der unter Druck stehenden Feder 28 verrastet. Das Steuerelement 30 stützt sich auf der Scheibe 27 ab, über die die Stange 10, die Rastklinke 7, und den in Position 90 eingreifenden Aktivator 9, und somit die Laufschiene 4 und den Schubkasten 1 fixiert. In der Schließlage sind die radial hervorstehenden Vorsprünge 31 im druckfederseitig abgewandten Wendepunkt einer Aufnahme an den Spitzen der hervorstehenden Abschnitte 15 gehalten. In dem dargestellten Ausführungsbeispiel sind zwei Vorsprünge 31 und 31' an gegenüberliegenden Seiten des Steuerelementes 30 vorgesehen, die beide in entsprechenden Rastaufnahmen fixiert sind.In FIG. 13A the locking position is shown in the closed position, in which the locking mechanism 30 locks the control member 30 against the force of the pressurized spring. The control 30 is supported on the disc 27, over which the rod 10, the latch 7, and engaging in position 90 activator 9, and thus the running rail 4 and the drawer 1 is fixed. In the closed position, the radially projecting projections 31 in the pressure spring side remote turning point of a recording at the tips of the protruding portions 15 are held. In the illustrated embodiment, two projections 31 and 31 'are provided on opposite sides of the control element 30, both of which are fixed in corresponding latching receptacles.

Um den Rastmechanismus aus der Schließposition zu lösen, wird entsprechend Figur 13B der Schubkasten 1 und damit über die Rastklinke 7 wobei der Aktivator am Vorsprung 92 anliegt, auch die Stange 10 entlang ihrer Längsachse 50 in Richtung der Feder 28 verschoben und die Feder 28 noch weiter zusammengedrückt. Beim Einschieben der Stange 10 wird das Steuerelement 30 gedreht, da die beiden Vorsprünge 31 an der flachergeneigten Seite des Abschnittes 15' bis zu der Feder 28 zugewandten Wendepunkte gleiten, die durch den Rand 15 gebildet ist.In order to release the latching mechanism from the closed position, the drawer 1 and thus the detent pawl 7 wherein the activator rests on the projection 92, and the rod 10 along its longitudinal axis 50 in the direction of the spring 28 is shifted and the spring 28 still further according to Figure 13B pressed together. When inserting the rod 10, the control element 30 is rotated, since the two projections 31 slide on the flat-inclined side of the section 15 'to the spring 28 facing turning points, which is formed by the edge 15.

Nachfolgend wird dann entsprechend Figur 13C der Schubkasten 1 losgelassen, wobei aufgrund der Federkraft die Vorsprünge 31 des Steuerelementes 30 an dem Abschnitt 15 der Steuerkurve 33 zur Anlage kommen aber nun nicht mehr in die Rastaufnahme 40 an der Spitze des Abschnittes 22 zurück gleiten, sondern an einer Spitze 41 der Steuerkurve vorbei geführt sind, so dass die Stange 10 aufgrund der Kraft der Druckfeder 28 in Öffnungsrichtung gedrückt wird, bis die in Figur 13D gezeigte Position erreicht ist. In dieser Position liegt das Steuerelement 30 an einem Anschlag 60 an, der an dem Gehäuseteil 20 ausgebildet ist. Der Anschlag 60 kann die Stange 10 in der hülsenförmigen Führung 32 geführt sein, wobei die Stange 10 einen geringeren Durchmesser als das Steuerelement 30 besitzt. Der Schubkasten 1 kann nun aus der leicht geöffneten Position an der Frontblende gegriffen werden und weiter in Öffnungsrichtung bewegt werden. In der in Figur 13D gezeigten Position gibt die Rastklinke 7 aufgrund der Anordnung in dem gebogenen Endabschnitt 80 den Aktivator 9 an der Laufschiene 4 frei.Below is then accordingly FIG. 13C the drawer 1 is released, due to the spring force, the projections 31 of the control element 30 come to rest on the portion 15 of the control cam 33 but no longer slide back into the locking receptacle 40 at the top of the section 22, but past a tip 41 of the control curve are guided so that the rod 10 is pressed in the opening direction due to the force of the compression spring 28 until the in FIG. 13D shown position is reached. In this position, the control element 30 bears against a stop 60 which is formed on the housing part 20. The stopper 60 may be guided in the sleeve-shaped guide 32, the rod 10, wherein the rod 10 has a smaller diameter than the control element 30. The drawer 1 can now be gripped from the slightly open position on the front panel and moved further in the opening direction. In the in FIG. 13D shown position, the latch 7 releases the activator 9 on the running rail 4 due to the arrangement in the bent end portion 80.

Wenn der Schubkasten 1 aus der geöffneten Position wieder geschlossen werden soll, schlägt der Aktivator 9 an den Vorsprung 92 an und über die Rastklinke 7 wird die Stange 10 gegen die Kraft der Feder 28 eingedrückt. Dadurch wird auch das Steuerelement 30 innerhalb der Steuerkurve bewegt, da das Steuerelement 30 in Axialrichtung mit der Stange 10 gekoppelt ist.When the drawer 1 is to be closed again from the open position, the activator 9 abuts against the projection 92 and via the latch 7, the rod 10 is pressed against the force of the spring 28. This will also the control member 30 moves within the cam, since the control member 30 is coupled in the axial direction with the rod 10.

Kurz vor Erreichen der vollständig eingefahrenen Position des Schubkastens 1 (Figur 13F) beginnt die Steuerkurve an dem Rand 15' des Gehäuseteils 13 auf die radialen Vorsprünge 31 zu wirken, so dass das ringförmige Steuerelement 30 um die Längsachse 50 gedreht wird. Dadurch liegen in der Endposition die Vorsprünge 31 dem der Druckfeder 28 zugewandten Wendepunkten, gebildet durch die Vorsprünge 15', gegenüberliegenden Rastaufnahmen 40 an der Spitze der Ränder 22 fest. Beim Loslassen des Schubkastens 1 bewegt sich dann aufgrund der Kraft der Feder 28 das Steuerelement 30 auf die Rastaufnahme 40, gebildet durch den Rand 15, zu, wobei die Vorsprünge 31 und 31' an einer Anlaufschräge 43 der Rastaufnahme 40 in Kontakt kommen und dadurch beim Zurückbewegen eine weitere Drehung des Steuerelementes 30 bewirken. Anschließend befindet sich der Rastmechanismus wieder in der in Figur 13A gezeigten Schließposition.Shortly before reaching the fully retracted position of the drawer 1 (Figure 13F), the control curve begins to act on the edge 15 'of the housing part 13 on the radial projections 31, so that the annular control member 30 is rotated about the longitudinal axis 50. Characterized lie in the final position, the projections 31 of the compression spring 28 facing turning points formed by the projections 15 ', opposite locking receptacles 40 at the top of the edges 22 fixed. When you release the drawer 1 then moves due to the force of the spring 28, the control 30 on the locking receptacle 40, formed by the edge 15, to, wherein the projections 31 and 31 'come into contact on a run-up slope 43 of the locking receptacle 40 and thereby the Move back to cause a further rotation of the control 30. Subsequently, the locking mechanism is again in the in FIG. 13A shown closed position.

Bei den in Figuren 13A bis 13F gezeigten Darstellungen ist auf der rechten Seite jeweils die Position der Vorsprünge 31 an dem Steuerelement 30 relativ zur Längsachse 50 dargestellt. Das Steuerelement 30 ist nicht entlang der Längsachse 50 verschiebbar an der Stange 10 gehalten jedoch drehbar gelagert, siehe Figuren 7 bis 12. Bei jedem Öffnen und Schließen des Schubkastens 1 dreht sich das Steuerelement 30, je nach Auslegung der Steuerkurve 33 um maximal 180°. Im Ausführungsbeispiel dreht sich das Steuerelement oszillierend um ca. 120°. Falls mehrere Vorsprünge 31 oder nur ein Vorsprung 31 an dem Steuerelement 30 vorgesehen sind, kann der Drehwinkel und Drehrichtung des Steuerelementes 30 entsprechend modifiziert werden. Zudem ist auch eine Drehung des Steuerelementes 30 nur in eine Drehrichtung um die Stange 10 möglich, so dass das Steuerelement 30 bei ein oder mehreren Schließzyklen umlaufend bewegt wird.At the in FIGS. 13A to 13F As shown, the position of the projections 31 on the control element 30 relative to the longitudinal axis 50 is shown on the right side. The control member 30 is not slidably held along the longitudinal axis 50 on the rod 10 but rotatably supported, see FIGS. 7 to 12 , With each opening and closing of the drawer 1, the control 30 rotates, depending on the design of the control cam 33 by a maximum of 180 °. In the exemplary embodiment, the control rotates oscillating by about 120 °. If a plurality of projections 31 or only one projection 31 are provided on the control element 30, the angle of rotation and direction of rotation of the control element 30 can be modified accordingly. In addition, a rotation of the control element 30 is only possible in a rotational direction about the rod 10, so that the control element 30 is moved circumferentially in one or more closing cycles.

In den. Figuren L4A und 14B ist ein zweites Ausführungsbeispiel einer Öffnungs-vorrichtung gezeigt, bei dem der Rastmechanismus gegenüber der ersten Ausführungsform modifiziert ausgebildet ist, wobei die gleichen Bauteile mit denselben Bezugszeichen bezeichnet sind. Bei diesem Rastmechanismus kann die Position der Schließposition verstellt werden. Es ist an dem Führungsgehäuse 6 ein Gehäuse 11' vorgesehen, das zwei relativ zueinander verstellbare hülsenförmige Gehäuseteile 12' und 20' aufweist. Das Gehäuseteil 20' ist dabei fest mit dem Führungsgehäuse 6 verbunden, während das Gehäuseteil 12' durch Drehen verstellbar ist, wie dies mit den Pfeilen angedeutet ist. In der geschlossenen Position des Schubkastens 1 wird ein Endanschlag aus dem Einschubanschlag 36 an der Rastklinke 7 und dem Einschubanschlag 35 an dem Führungsgehäuse 6 gebildet.In the. Figures L4A and 14B, a second embodiment of an opening device is shown in which the latching mechanism is formed modified relative to the first embodiment, wherein the same components are denoted by the same reference numerals. In this locking mechanism, the position of the closed position can be adjusted. It is on the guide housing 6, a housing 11 'is provided, the two relatively adjustable sleeve-shaped housing parts 12' and 20 '. The housing part 20 'is fixedly connected to the guide housing 6, while the housing part 12' is adjustable by turning, as indicated by the arrows. In the closed position of the drawer 1, an end stop is formed from the insertion stop 36 on the latch 7 and the insertion stop 35 on the guide housing 6.

In den Figuren 15A und 15B ist die Funktion des Verstellens der Gehäuseteile 20' und 12' dargestellt. Durch Drehen des hülsenförmigen Gehäuseteils 12' verschiebt sich die Position des hülsenförmigen Gehäuseteils 12' relativ zu dem feststehenden Gehäuseteil 20'. Dadurch wird auch die Position der Stange 10 verstellt, an der die Rastklinke 7 und entsprechend der Schubkasten 1 gekoppelt ist.In the FIGS. 15A and 15B the function of adjusting the housing parts 20 'and 12' is shown. By rotating the sleeve-shaped housing part 12 ', the position of the sleeve-shaped housing part 12' shifts relative to the stationary housing part 20 '. As a result, the position of the rod 10 is adjusted to which the latch 7 and according to the drawer 1 is coupled.

Wie aus Figur 16 hervorgeht, weist das fest an dem Führungsgehäuse 6 gekoppelte Gehäuseteil 20' einen Gewindeabschnitt 29 auf, dessen Außengewinde mit einem Innengewinde an dem Gehäuseteil 21' in Eingriff steht. Das Gehäuseteil 21' ist über einen oder mehrere Vorsprünge 23 mit dem hülsenförmigen Gehäuseteil 12' verrastet. Ferner ist auch das äußere Gehäuseteil 13 mit dem hülsenförmigen Gehäuseteil 12' verrastet.How out FIG. 16 shows, the fixedly coupled to the guide housing 6 housing part 20 'has a threaded portion 29, whose external thread with an internal thread on the housing part 21' is engaged. The housing part 21 'is latched via one or more projections 23 with the sleeve-shaped housing part 12'. Furthermore, the outer housing part 13 with the sleeve-shaped housing part 12 'is locked.

Das hülsenförmige Gehäuseteil 12' weist am äußeren Umfang mehrere Rippen 25' auf, die zum leichteren Drehen dienen. Wenn das hülsenförmige Gehäuseteil 12' gedreht wird, bewegt sich die Einheit aus hülsenförmigen Gehäuseteil 12', äußere Gehäuseteil 13 und Gehäuseteil 21' relativ zu dem feststehenden Gehäuseteil 20'. An dem Gehäuseteil 21' ist an einem hülsenförmigen Abschnitt die Rastaufnahme 40 ausgebildet, an der die Vorsprünge 31 des ringförmigen Steuerelementes 30 festgelegt werden können. Dadurch wird beim Drehen des hülsenförmigen Gehäuseteils 12' auch die Position der Rastaufnahme 40 relativ zu dem Führungsgehäuse 6 verstellt, was entsprechend eine Verstellung des Schubkastens 1 relativ zu dem umgebenden Möbelkorpus bewirkt. Somit kann der Spalt zwischen Frontblende und Möbelkorpus reguliert werden. Hierdurch kann der Spalt so justiert werden, das eine hohe Betriebssicherheit für die Öffnungsvorrichtung erreicht wird.The sleeve-shaped housing part 12 'has on the outer circumference a plurality of ribs 25', which serve to facilitate turning. When the sleeve-shaped housing part 12 'is rotated, the unit of sleeve-shaped housing part 12', outer housing part 13 and housing part 21 'moves relative to the fixed housing part 20'. On the housing part 21 ', the locking receptacle 40 is formed on a sleeve-shaped portion, on which the projections 31 of the annular control element 30 can be fixed. As a result, the position of the latching receptacle 40 relative to the guide housing 6 is adjusted when turning the sleeve-shaped housing part 12 ', which causes an adjustment of the drawer 1 relative to the surrounding furniture body accordingly. Thus, the gap between front panel and furniture body can be regulated. As a result, the gap can be adjusted so that a high reliability for the opening device is achieved.

Die Funktion der Öffnungsvorrichtung ist im Übrigen wie bei dem ersten Ausführungsbeispiel ausgebildet, insbesondere bewegt sich das ringförmige Steuerelement 30 entsprechend der beschriebenen Steuerkurve.The function of the opening device is otherwise formed as in the first embodiment, in particular, the annular control member 30 moves according to the described control curve.

In Figur 17 ist eine geschnittene Seitenansicht des Gehäuses 11 dargestellt, wobei das Eingreifen der hülsenförmigen Abschnitte 14 und 21 in das hülsenförmige Gehäuseteil 12 sichtbar sind. Dadurch bildet sich in dem Gehäuse 11 eine zylindrische Führung aus, die als Linearführung für die Scheibe 27 an der Stange 10 wirkt. Ferner kann über die beschriebene Steuerkurve 33 das ringförmige Steuerelement 30 auch um die Längsachse 50 gedreht werden.In FIG. 17 is a sectional side view of the housing 11 is shown, wherein the engagement of the sleeve-shaped portions 14 and 21 in the sleeve-shaped housing part 12 are visible. As a result, a cylindrical guide is formed in the housing 11, which acts as a linear guide for the disk 27 on the rod 10. Furthermore, the annular control element 30 can also be rotated about the longitudinal axis 50 via the described control cam 33.

In den dargestellten Ausführungsbeispielen wird die Steuerkurve 33 durch zwei Gehäuseteile 13 und 20 ausgebildet, die auf das ringförmige Steuerelement 30 einwirken. Es ist dann natürlich auch möglich, in dem hülsenförmigen Gehäuseteil 12 eine Aussparung vorzusehen, die die Wand des Gehäuseteils ganz oder teilweise durchgreift und dann eine Steuerkurve für einen oder mehrere Vorsprünge 31 des Steuerelemente 30 bildet.In the illustrated embodiments, the control cam 33 is formed by two housing parts 13 and 20 which act on the annular control element 30. It is then of course also possible to provide in the sleeve-shaped housing part 12 a recess which passes through the wall of the housing part completely or partially and then forms a control cam for one or more projections 31 of the control elements 30.
