- the first teeth 44 each have a first tooth flank 50a, which extend upwards from the base body 49 in the installed position and run at an angle to the mounting direction.
- the first tooth flank 50a meets at the tooth tip with a second tooth flank 50b, which is aligned essentially perpendicularly to the attachment direction 39, as a result of which the first and second tooth flanks 50a, 50b form an approximately right-angled triangle in cross section.
- the longitudinal axis 45 of the first teeth 44 runs essentially perpendicular to the attachment direction 39, but in the plane of the base body 25.
- the second tooth flank 50b also extends essentially perpendicular to the attachment direction 39, but this runs in the height direction 29 of the base body 25
- unlocking element 41 which is figure 4 is formed, for example, as a release lever mounted about a pivot axis 51 on the base body 25 of the clutch unit 24 .
- the unlocking lever has an actuating section 52 which, in the coupled state of furniture extension 14, i.e. drawer, with the running rail 15 from the bottom of the Furniture excerpt is easily accessible and easily actuated by finger pressure.
- the actuating section 52 of the unlocking lever is in particular connected in one piece to a bearing section 53, at the end of which the already mentioned base body of the locking teeth 43 with the first teeth 44 is located.

- the unlocking lever and its components are expediently made of plastic; in particular, the unlocking lever can be a plastic injection molded component.
- the pivot axis 51 of the unlocking lever is expediently a flexure joint.
- the movement of the unlocking element 41 in the form of the unlocking lever in the release direction 42 takes place against the spring force of a return spring 54.
- the return spring 54 By means of the return spring 54, the locking toothing 53 with the first teeth 44 is always issued in a position in which, if the corresponding counter-locking toothing 46 with the second teeth 47 were present, a locking engagement would occur.
- the unlocking lever is thus moved by actuating the actuating section 52 against the spring force of the return spring 54, as a result of which the first and second teeth 44, 47 come out of the locking engagement.
- the counterpart of the locking toothing 43 is the counter-locking toothing 46 which is assigned to the counter-locking element 38 on the running rail 15 .
- the counter-locking element 38 has, in addition to the counter-locking teeth, a fastening section 55 for fastening the counter-locking element to the running rail 15.
- the fastening section 55 is simply attached to the open front end 34 of the running rail.
- the fastening section 55 has an opening 56 through which a fastening pin 57 on the fixing section 33 of the base body 25 of the coupling unit 24 can be inserted.
- the counter-locking toothing 46 also has a base body 58 which, in contrast to the plate-like, web-shaped base body 49 of the locking toothing 43, is designed in the form of strips.
- the second teeth 47 are shaped out of the base body 58 .
- the second teeth 47 are directed downwards along the vertical axis of the running rail 15 in the installed position.
- the second teeth 47 of the counter-locking toothing 46 correspond to the first teeth 44 of the locking toothing 43.
- the second teeth 47 each have two tooth flanks 59a, 59b, of which a first tooth flank 59a runs along the vertical axis of the running rail and is inclined in relation to the mounting direction 39 is trained.
- the adjoining second tooth flank 59b runs essentially perpendicular to the attachment direction 39 along the height axis of the running rail 15.
- the two tooth flanks 59a, 59b meet in a tooth tip which, as mentioned, also runs transversely to the attachment direction 39 with its longitudinal axis, but also transversely to the height direction of the slide rail 15.
- the first and second tooth flanks 59a, 59b in cross section form a tooth 47 with a sawtooth shape in the form of a right-angled triangle.
- the coupling devices 11 are first mounted in the manner described above in the area of the bottom of the furniture extension 14 in the area of the two opposite side walls of the furniture extension 14 . Thereafter, the pre-assembled assembly of furniture pull-out 14 and coupling devices 11 is mounted on the rails 15. Only the assembly of one of the coupling devices 11 on the associated running rail 15 is explained below.
- the coupling device 11 is brought into the region of the front end 34 of the running rail 15 with its web-like fixing section 33 and the fastening pin 57 protruding there.
- the fastening pin 57 moves through the opening 56 of the fastening section 55 of the counter-locking element 38 and, at the same time, the first teeth 44 of the locking toothing 43 pointing upwards come into contact with the second teeth 47 of the counter-locking toothing 46 pointing downwards, whereby the material of the locking element 37 and the counter-locking element 38, in particular plastic material, allows a displacement of the counter-locking element 38 or locking element 37 in the vertical direction, so that the first and second teeth 44, 47 engage in one another, in particular can snap into one another, as a result of which the locking engagement occurs .
- the fastening pin 57 on the web-like fixing section 33 of the base body 25 can be inserted more or less far beyond the opening 56 into the open front end 34 of the running rail 15, whereby a displacement or change in position of the coupling device 11 and thus the furniture pull-out 14 in relation to the running rail 15 in the mounting direction 39 is possible.
- the above-mentioned attachment thus takes place in the attachment direction 39, which is aligned along the longitudinal axis 35 of the running rail 15, while the locking, i.e. the locking engagement of the first and second teeth 44, 47, takes place transversely to the attachment direction 39 in the locking direction 40.
- the locking direction 40 runs in the vertical direction of the running rail or the base body 25 of the coupling unit 24.
- the actuating section 52 of the unlocking lever is actuated by finger pressure. Finger pressure causes the unlocking lever to pivot. It is important here that the release direction 42 lies in a different plane than the locking direction 40 . In this case, the release direction 42 is not aligned opposite to the locking direction 40, but lies in another plane offset by 90° to the locking direction 40. In the example shown, the release direction 42 is oriented in the same direction as the longitudinal axes of the teeth 44, 47. In the example shown, the release direction 42 is also transverse to the attachment direction 39 but also transverse to the locking direction 40. The unlocking lever therefore makes a movement in the plane of the base body, i.e. it is moved away from the running rail, so that the first teeth 44 on the locking teeth 43 are out of the second teeth 47 of the counter-locking toothing 46 shear out.
- the figures 7 and 8th show a second embodiment of the coupling device 11 according to the invention.
- the coupling unit 24 is identical to the coupling unit 24 of the first Embodiment formed, with the exception of the orientation of the first teeth 44.
- the counter-locking element 38 shown is designed in an identical manner to the counter-locking element of the first exemplary embodiment, with the exception of the orientation of the second teeth 47.
- the first teeth 44 on the base body 49 of the locking toothing 43 do not protrude upwards, but rather extend in the plane of the coupling unit base body 25, ie are from the base body 49 of the locking toothing 43 outwards.
- the second teeth 47 are aligned in such a way that their longitudinal axes 48 run in the vertical direction of the running rail.
- the second teeth 47 are formed from the associated base body 58 in such a way that they protrude laterally from the base body.
- the fastening of the coupling device 11 to the associated running rail 15 is initially carried out in an identical manner to the first exemplary embodiment.
- the attachment direction 39 again runs along the longitudinal axis of the running rail 15.
- the locking direction 40 is aligned transversely to the attachment direction 39, but in contrast to the first exemplary embodiment described above does not run in the vertical direction but in the plane of the base body 25 of the coupling unit 24.
- the actuating section 52 of the unlocking lever applied by finger pressure.
- the unlocking lever is not pivoted in the plane of the base body 25 of the coupling unit, but is moved downwards, i.e. in the vertical direction of the running rail 15.
- the release direction 42 therefore runs transversely to the attachment direction 39 and also transversely to the locking direction 40 and in in this case in the vertical direction of the running rail 15.

Description
Die Erfindung betrifft eine Kupplungsvorrichtung zur lösbaren Verbindung eines in einem Möbelkorpus über eine Führungseinheit beweglich geführten Möbelauszugs mit einer Laufschiene der Führungseinheit, mit einer einen Grundkörper aufweisenden Kupplungseinheit und mit einer zu Kupplungsvorrichtung gehörenden Verriegelungseinrichtung, die ein an der Kupplungseinheit angeordnetes Verriegelungselement und ein an der Laufschiene angeordnetes Gegen-Verriegelungselement aufweist, wobei das Verriegelungselement und das Gegen-Verriegelungselement beim in einer Aufsteckrichtung erfolgenden Aufstecken unter federelastischer Auslenkung eines dieser beiden Elemente in einer quer zur Aufsteckrichtung orientieren Verriegelungsrichtung in Verriegelungseingriff bringbar sind, und wobei die Verriegelungseinrichtung ein Entriegelungselement zum Lösen des Verriegelungselements durch Bewegung des Verriegelungselementes in einer Löserichtung aufweist.The invention relates to a coupling device for the detachable connection of a furniture pull-out, which is movably guided in a furniture carcass via a guide unit, to a runner of the guide unit, to a coupling unit having a base body and to a locking device belonging to the coupling device, which has a locking element arranged on the coupling unit and a locking element on the runner arranged counter-locking element, wherein the locking element and the counter-locking element can be brought into locking engagement when plugged on in a plug-on direction with resilient deflection of one of these two elements in a locking direction oriented transversely to the plug-on direction, and wherein the locking device has an unlocking element for releasing the locking element Having movement of the locking element in a release direction.
Kupplungsvorrichtungen zur lösbaren Verbindung eines in einem Möbelkorpus über eine Führungseinheit beweglich geführten Möbelauszugs sind bereits seit langem bekannt, wie zum Beispiel aus
Solche aus dem Stand der Technik bekannten Rastkupplungen zeichnen sich sowohl durch einfache Montierbarkeit als auch durch einfache Handhabung aus. Beispielsweise ist es möglich, eine vormontierte Baugruppe aus Schublade und am Boden der Schubladen montierten Rastkupplungen bereitzustellen, die dann in einfacher Weise an den zugeordneten Laufschienen zu befestigen sind. Das Befestigen an der zugeordneten Laufschiene erfolgt in vorteilhafter Weise mittels Aufstecken der Rastkupplung auf die zugeordnete Laufschiene, wobei ein Verriegelungselement an der Rastkupplung und ein Gegen-Verriegelungselement an der Laufschiene in Verriegelungseingriff zueinander gelangen, insbesondere ineinander einschnappen.Such locking couplings known from the prior art are characterized both by simple assembly and by simple handling. For example, it is possible to provide a preassembled assembly of drawers and snap-in couplings mounted on the bottom of the drawers, which can then be attached to the associated running rails in a simple manner. Fastening to the associated running rail is advantageously carried out by plugging the latching coupling onto the associated running rail, with a locking element on the latching coupling and a counter-locking element on the running rail lockingly engaging one another, in particular snapping into one another.
Das Problem herkömmlicher Rastkupplungen ist das Entriegeln bzw. Lösen von der zugeordneten Laufschiene. Hierzu dient ein Entriegelungselement, das zum Lösen in eine Löserichtung bewegt wird. Hier kann es jedoch vorkommen, dass Verriegelungselement und Gegen-Verriegelungselement beim Lösen nicht außer Eingriff zueinander gelangen, sondern sich noch mehr ineinander verkrallen, insbesondere falls das Verriegelungselement und das Gegen-Verriegelungselement jeweils als Verzahnungen ausgebildet sind und die Kupplungsverzahnung mit einem Hinterschnitt ausgestattet ist.The problem with conventional snap-in couplings is unlocking or detaching from the associated running rail. An unlocking element is used for this purpose, which is moved in a release direction for release. Here, however, it can happen that the locking element and counter-locking element do not disengage from each other when released, but instead dig into each other even more, especially if the locking element and the counter-locking element are each designed as teeth and the coupling teeth are equipped with an undercut.
Aufgabe der Erfindung ist es, eine Kupplungsvorrichtung der eingangs erwähnten Art zu schaffen, die gegenüber herkömmlichen Kupplungsvorrichtungen einfacher handhabbar ist, insbesondere dessen Verriegelung im Vergleich zu herkömmlichen Kupplungsvorrichtungen leichter zu lösen ist.The object of the invention is to provide a coupling device of the type mentioned at the outset, which is easier to handle than conventional coupling devices, and in particular whose locking is easier to release than conventional coupling devices.
Diese Aufgabe wird durch eine Kupplungsvorrichtung mit den Merkmalen des unabhängigen Anspruchs 1 gelöst. Weiterbildungen der Erfindung sind in den Unteransprüchen dargestellt. Die erfindungsgemäße Kupplungsvorrichtung zeichnet sich dadurch aus, dass die Löserichtung quer zur Aufsteckrichtung und quer zur Verriegelungsrichtung orientiert ist.This object is solved by a coupling device having the features of independent claim 1 . Further developments of the invention are presented in the dependent claims. The coupling device according to the invention is characterized in that the release direction is oriented transversely to the push-on direction and transversely to the locking direction.
Die Löserichtung des Verriegelungselements liegt also nicht in derselben Ebene wie die Verriegelungsrichtung. Ferner liegt sie auch nicht in derselben Ebene wie die Aufsteckrichtung. Es ist also möglich, dass Löserichtung, Aufsteckrichtung und Verriegelungsrichtung ein kartesisches Koordinatensystem mit den Vektoren x, y und z bilden. Dadurch, dass die Löserichtung in einer anderen Ebene als die Verriegelungsrichtung liegt, wird das zuvor beschriebene Problem vermieden, dass sich Verriegelungselement und Gegen-Verriegelungselement beim Betätigen des Entriegelungselements verklemmen.The release direction of the locking element is therefore not in the same plane as the locking direction. Furthermore, it is also not in the same plane as the plug-on direction. It is therefore possible for the release direction, attachment direction and locking direction to form a Cartesian coordinate system with the vectors x, y and z. The fact that the release direction is in a different plane than the locking direction avoids the previously described problem of the locking element and counter-locking element jamming when the unlocking element is actuated.
Bei einer Weiterbildung der Erfindung weist das Verriegelungselement eine zahnleistenartige Verriegelungsverzahnung mit mehreren in Aufsteckrichtung hintereinander angeordneten, mit zueinander parallel ausgerichteten Längsachsen ausgestatteten ersten Zähnen und das Gegen-Verriegelungselement eine zahnleistenartige Gegen-Verriegelungsverzahnung mit mehreren in Aufsteckrichtung hintereinander angeordneten mit zueinander parallel ausgerichteten Längsachsen ausgestatteten zweiten Zähnen auf, wobei die Verzahnungen in Verriegelungsrichtung in Verzahnungseingriff zueinander bringbar sind, und wobei die Löserichtung zu den Längsachsen der Zähne gleich gerichtet ist.In a development of the invention, the locking element has a rack-like locking toothing with a plurality of first teeth arranged one behind the other in the plug-on direction and equipped with longitudinal axes aligned parallel to one another, and the counter-locking element has a toothed rack-like counter-locking tooth system with a plurality of second teeth arranged one behind the other in the plug-on direction and equipped with longitudinal axes aligned parallel to one another on, wherein the toothings can be brought into toothing engagement with one another in the locking direction, and wherein the release direction is directed in the same way as the longitudinal axes of the teeth.
In diesem Fall erfolgt das Lösen also durch das aneinander Abscheren der ersten und zweiten Zähne der Verzahnungen.In this case, the loosening takes place by the first and second teeth of the toothing shearing off one another.
Bei einer Weiterbildung der Erfindung weist der Grundkörper der Kupplungseinheit eine Unterseite auf, die mit einer Montageschnittstelle zur Montage an den Möbelauszug ausgestattet ist und besitzt eine der Laufschiene im Gebrauchszustand zugewandte Oberseite, wobei zwischen der Unterseite und der Oberseite eine Höhenachse des Grundkörpers verläuft.In a further development of the invention, the base body of the clutch unit has an underside which is provided with an assembly interface is equipped for mounting on the furniture pull-out and has an upper side facing the running rail when in use, with a vertical axis of the base body running between the lower side and the upper side.
Die Längsachse der ersten und zweiten Zähne der Verzahnungen kann mit der Höhenachse des Grundkörpers gleichgerichtet sein.The longitudinal axis of the first and second teeth of the toothing can be aligned with the vertical axis of the base body.
Alternativ und bevorzugt ist es, dass die Längsachse der ersten und zweiten Zähne der Verzahnungen quer, insbesondere rechtwinklig zur Höhenachse ausgerichtet ist.Alternatively and preferably, the longitudinal axis of the first and second teeth of the toothing is aligned transversely, in particular at right angles, to the vertical axis.
In besonders bevorzugter Weise ist das Entriegelungselement in einer Bewegungsrichtung bewegbar, die quer, insbesondere rechtwinklig, zur Höhenachse des Grundkörpers orientiert ist.In a particularly preferred manner, the unlocking element can be moved in a direction of movement which is oriented transversely, in particular at right angles, to the vertical axis of the base body.
Alternativ ist es möglich, dass das Entriegelungselement in einer Bewegungsrichtung bewegbar ist, die zur Höhenachse des Grundkörpers gleichgerichtet ist.Alternatively, it is possible for the unlocking element to be movable in a direction of movement that is oriented in the same direction as the vertical axis of the base body.
Bei einer Weiterbildung der Erfindung erfolgt die Bewegung des Entriegelungselements in Löserichtung gegen die Federkraft einer Rückstellfeder. Der Einsatz einer Rückstellfeder ist jedoch nicht zwingend notwendig, da es lediglich darauf ankommt, dass die quer zur Löserichtung ausgerichtete Verriegelungsrichtung Federkraft unterstützt ist, damit der Verriegelungseingriff unter Federspannung bestehen bleibt.In a development of the invention, the unlocking element is moved in the release direction against the spring force of a return spring. However, the use of a return spring is not absolutely necessary, since it is only important that the locking direction, which is aligned transversely to the release direction, is supported by spring force, so that the locking engagement remains under spring tension.
Bei einer Weiterbildung der Erfindung ist das Entriegelungselement als um eine Schwenkachse schwenkbar am Grundkörper gelagerter Entriegelungshebel ausgebildet.In a further development of the invention, the unlocking element is designed as an unlocking lever mounted on the base body so that it can pivot about a pivot axis.
Bei einer Weiterbildung der Erfindung umfasst die Kupplungsvorrichtung eine Laufschiene mit daran angeordnetem Gegen-Verriegelungselement.In a development of the invention, the coupling device comprises a running rail with a counter-locking element arranged thereon.
Die Erfindung umfasst ferner ein Möbel, mit einem relativ zu einem Möbelkorpus bewegbaren, über eine eine Laufschiene aufweisenden Führungseinheit geführten Möbelauszug, der sich durch eine Kupplungsvorrichtung nach einem der Ansprüche 1 bis 10 auszeichnet.The invention also includes a piece of furniture with a furniture pull-out that can be moved relative to a furniture body and is guided via a guide unit having a running rail, which is characterized by a coupling device according to one of claims 1 to 10.

Die Kupplungsvorrichtung 11 umfasst hierzu mehrere Komponenten, von denen eine eine Kupplungseinheit 24 ist. Die Kupplungseinheit 24, die auch als Rastkupplung bezeichnet werden könnte, besitzt einen Grundkörper 25, der relativ flach ausgebildet ist. Der Grundkörper 25 besteht zweckmäßigerweise aus Kunststoffmaterial, beispielsweise kann er als Kunststoffspritzgieß-Bauteil ausgestaltet sein. Alternativ ist es denkbar, dass der Grundkörper 25 als Metallteil, beispielsweise Metallguss-Formteil ausgebildet ist.For this purpose, the
Der Grundkörper 25 weist eine Unterseite 26 auf, die mit einer Montageschnittstelle 27 zur Montage an den Möbelauszug 14, also beispielsweise Schublade, ausgestattet ist. Ferner besitzt der Grundkörper 25 eine der Laufschiene 15 zugewandte Oberseite 28, wobei zwischen der Unterseite 26 und der Oberseite 28 eine Höhenachse 29 des Grundkörpers 25 verläuft.The
Die
Der Grundkörper 25 besitzt einen Montageabschnitt 30, der an seiner Oberseite eine rinnenartige Vertiefung 31 aufweist. An der Unterseite des Montageabschnitts 30 befindet sich die Montageschnittstelle 27. Der Montageabschnitt 30 ist entlang der Höhenachse 29 von mehreren Montagelöchern, beispielsweise zwei quer zur Höhenachse 29 beabstandet voneinander angeordneten Montagelöcher 32, durchsetzt. Zum Befestigen der Kupplungseinheit an der Unterseite des Bodens 64 des Möbelauszugs 14 64 werden die Montagelöcher 32 von geeigneten Montageelementen, beispielsweise Befestigungsschrauben durchsetzt. Die rinnenartige Vertiefung 31 sorgt dafür, dass die Montageköpfe der Montageelemente nicht über die Oberseite 28 des Grundkörpers hinausstehen. Für den Fall, dass die Front 65 des Möbelauszugs 14 von der Unterseite des Möbelauszug-Bodens 64 nach unten absteht, sind zwei weitere Montagelöcher 66 vorgesehen, um die Kupplungseinheit 24 an dem nach unten überstehenden Abschnitt der Front 65 zu befestigen.The
An dem Montageabschnitt 30 ist im Wesentlichen rechtwinklig hierzu abstehend ein steg- oder fingerartiger Fixierabschnitt 33 angesetzt, insbesondere einstückig mit dem Montageabschnitt 30 verbunden. Wie insbesondere in

Ein wichtiges Element der Kupplungseinheit 24 ist das bereits erwähnte Entriegelungselement 41, das in
Der Entriegelungshebel weist einen Betätigungsabschnitt 52 auf, der im gekuppelten Zustand von Möbelauszug 14, also Schublade, mit der Laufschiene 15 von Seiten des Bodens des Möbelauszugs leicht erreichbar und durch Fingerdruck einfach betätigbar ist. Der Betätigungsabschnitt 52 des Entriegelungshebels ist insbesondere einstückig mit einem Lagerabschnitt 53 verbunden, an dessen Ende sich der bereits erwähnte Grundkörper der Verriegelungsverzahnung 43 mit den ersten Zähnen 44 befindet. Zweckmäßigerweise bilden Betätigungsabschnitt 52, Lagerabschnitt 53 des Entriegelungshebels und der Grundkörper 49 der Verriegelungsverzahnung 43 ein einstückiges Bauteil. Zweckmäßigerweise besteht der Entriegelungshebel mit seinen Komponenten aus Kunststoff, insbesondere kann es sich bei dem Entriegelungshebel um ein Kunststoffspritzgieß-Bauteil handeln. Bei der Schwenkachse 51 des Entriegelungshebels handelt es sich zweckmäßigerweise um ein Festkörpergelenk.The unlocking lever has an
Zweckmäßigerweise erfolgt die Bewegung des Entriegelungselements 41 in Form des Entriegelungshebels in Löserichtung 42 gegen die Federkraft einer Rückstellfeder 54. Im gezeigten Beispielsfall ist die Rückstellfeder 54, die insbesondere durch einen einstückig am Lagerabschnitt 53 angeformten Materialstreifen gebildet. Mittels der Rückstellfeder 54 wird die Verriegelungsverzahnung 53 mit den ersten Zähnen 44 stets in eine Position ausgestellt, in der bei Anwesenheit der korrespondierenden Gegen-Verriegelungsverzahnung 46 mit den zweiten Zähnen 47 ein Verriegelungseingriff entstehen würde. Zum Lösen wird der Entriegelungshebel also durch Betätigen des Betätigungsabschnitts 52 entgegen der Federkraft der Rückstellfeder 54 bewegt, wodurch die ersten und zweiten Zähne 44, 47 aus der Verriegelungseingriff gelangen.Expediently, the movement of the unlocking
Wie bereits erwähnt ist das Gegenstück der Verriegelungsverzahnung 43 die Gegen-Verriegelungsverzahnung 46, die dem Gegen-Verriegelungselement 38 an der Laufschiene 15 zugeordnet ist.As already mentioned, the counterpart of the locking
Wie beispielsweise in
Die Gegen-Verriegelungsverzahnung 46 besitzt ebenfalls einen Grundkörper 58, der jedoch im Gegensatz zum plattenartigen, stegförmigen Grundkörper 49 der Verriegelungsverzahnung 43 leistenförmig ausgebildet ist. Im gezeigten Beispielsfall sind die zweiten Zähne 47 aus dem Grundkörper 58 herausgeformt. Die zweiten Zähne 47 sind entlang der Höhenachse der Laufschiene 15 in Einbaulage nach unten gerichtet. Die zweiten Zähne 47 der Gegen-Verriegelungsverzahnung 46 korrespondieren mit den ersten Zähnen 44 der Verriegelungsverzahnung 43. Die zweiten Zähne 47 besitzen jeweils zwei Zahnflanken 59a, 59b, von denen eine erste Zahnflanke 59a entlang der Höhenachse der Laufschiene verläuft und im Bezug zur Aufsteckrichtung 39 schräg ausgebildet ist. Die sich daran anschließende zweite Zahnflanke 59b verläuft im Wesentlichen senkrecht zur Aufsteckrichtung 39 entlang der Höhenachse der Laufschiene 15. Die beiden Zahnflanken 59a, 59b treffen sich in einer Zahnspitze, die, wie erwähnt mit ihrer Längsachse ebenfalls quer zur Aufsteckrichtung 39 verläuft, jedoch auch quer zur Höhenrichtung der Laufschiene 15. Insgesamt bilden erste und zweite Zahnflanken 59a, 59b im Querschnitt einen Zahn 47 mit Sägezahnform in Form eines rechtwinkligen Dreiecks.The
Zur lösbaren Verbindung des Möbelauszugs 14 in Form der Schublade mit der Laufschiene, werden zunächst im Bereich des Bodens des Möbelauszugs 14 im Bereich der beiden einander gegenüberliegenden Seitenwänden des Möbelauszugs 14 die Kupplungsvorrichtungen 11 in zuvor beschriebener Weise montiert. Danach wird die vormontierte Baugruppe aus Möbelauszug 14 und Kupplungsvorrichtungen 11 an den Laufschienen 15 montiert. Im Folgenden wird lediglich die Montage einer der Kupplungsvorrichtungen 11 an der zugeordneten Laufschiene 15 erläutert.For detachable connection of the
Die Kupplungsvorrichtung 11 wird mit ihrem stegartigen Fixierabschnitt 33 und dem dort hervorstehenden Befestigungszapfen 57 in den Bereich des stirnseitigen Endes 34 der Laufschiene 15 gebracht. Als nächstes fährt der Befestigungszapfen 57 durch die Durchbrechung 56 des Befestigungsabschnitts 55 des Gegen-Verriegelungselements 38 ein und gleichzeitig kommen die nach oben stehenden ersten Zähne 44 der Verriegelungsverzahnung 43 mit den nach unten stehenden zweiten Zähnen 47 der Gegen-Verriegelungsverzahnung 46 miteinander in Kontakt, wobei das Material des Verriegelungselements 37 und des Gegen-Verriegelungselements 38, insbesondere Kunststoffmaterial, eine Verlagerung von Gegen-Verriegelungselement 38 oder Verriegelungselement 37 in Höhenrichtung erlaubt, so dass erste und zweite Zähne 44, 47 ineinander eingreifen, insbesondere ineinander einschnappen können, wodurch der Verriegelungseingriff entsteht.The

Das zuvor erwähnte Aufstecken erfolgt also in der Aufsteckrichtung 39, die entlang der Längsachse 35 der Laufschiene 15 ausgerichtet ist, während das Verriegeln also der Verriegelungseingriff der ersten und zweiten Zähne 44, 47 quer zur Aufsteckrichtung 39 in der Verriegelungsrichtung 40 erfolgt. Die Verriegelungsrichtung 40 verläuft in diesem Fall in Höhenrichtung der Laufschiene bzw. des Grundkörpers 25 der Kupplungseinheit 24.The above-mentioned attachment thus takes place in the
Zum Lösen des Verriegelungseingriffs und somit zum Lösen den Möbelauszugs 14 von der Laufschiene 15 wird der Betätigungsabschnitt 52 des Entriegelungshebels über Fingerdruck betätigt. Der Fingerdruck bewirkt ein Verschwenken des Entriegelungshebels. Wichtig hierbei ist, dass die Löserichtung 42 in einer anderen Ebene als die Verriegelungsrichtung 40 liegt. Die Löserichtung 42 ist in diesem Fall also nicht entgegengesetzt zur Verriegelungsrichtung 40 ausgerichtet, sondern liegt in einer anderen Ebene 90° versetzt zu der Verriegelungsrichtung 40. Im gezeigten Beispielsfall ist die Löserichtung 42 zu den Längsachsen der Zähne 44, 47 gleich gerichtet. Im gezeigten Beispielsfall liegt die Löserichtung 42 ebenfalls quer zur Aufsteckrichtung 39 aber auch quer zur Verriegelungsrichtung 40. Der Entriegelungshebel macht also eine Bewegung in der Ebene des Grundkörpers, wird also von der Laufschiene wegbewegt, so dass die ersten Zähne 44 an der Verriegelungsverzahnung 43 aus den zweiten Zähnen 47 der Gegen-Verriegelungsverzahnung 46 ausscheren.To release the locking engagement and thus to release the furniture pull-out 14 from the running

Das Befestigen der Kupplungsvorrichtung 11 an der zugeordneten Laufschiene 15 erfolgt zunächst in identischer Weise zum ersten Ausführungsbeispiel. Die Aufsteckrichtung 39 verläuft wieder entlang der Längsachse der Laufschiene 15. Jedoch ist die Verriegelungsrichtung 40 quer zur Aufsteckrichtung 39 ausgerichtet, verläuft aber im Gegensatz zum zuvor beschriebenen ersten Ausführungsbeispiel nicht in Höhenrichtung sondern in der Ebene des Grundkörpers 25 der Kupplungseinheit 24. Beim Einstecken des Befestigungszapfens 47 wird die Verriegelungsverzahnung 43 mit den ersten Zähnen 44 entgegen der Federkraft der Rückstellfeder 54 ausgelenkt, wodurch die ersten und zweiten Zähne 44, 47 ineinander einschnappen können, wodurch der Verriegelungseingriff entsteht.The fastening of the
Zum Entriegeln wird ebenfalls wieder wie beim zuvor beschriebenen ersten Ausführungsbeispiel der Betätigungsabschnitt 52 des Entriegelungshebels durch Fingerdruck beaufschlagt. Im Gegensatz zum zuvor beschriebenen Ausführungsbeispiel wird der Entriegelungshebel jedoch nicht in der Ebene des Grundkörpers 25 der Kupplungseinheit verschwenkt, sondern nach unten bewegt, also in Höhenrichtung der Laufschiene 15. Die Löserichtung 42 verläuft also quer zur Aufsteckrichtung 39 und auch quer zur Verriegelungsrichtung 40 und in diesem Fall in Höhenrichtung der Laufschiene 15.For unlocking, as in the first exemplary embodiment described above, the
