Im Weiteren betrifft die Erfindung ein Möbel mit einem Möbelkorpus und mit einer Schublade, welche über eine Schubladenausziehführung der zu beschreibenden Art relativ zum Möbelkorpus verfahrbar gelagert ist. Furthermore, the invention relates to a piece of furniture with a furniture body and with a drawer, which is movably mounted relative to the furniture body via a drawer extension of the type to be described.
In der EP 0 868 866 B1 ist eine Schubladenausziehführung mit einer Korpusschiene und einer bewegbar gelagerten Ausziehschiene gezeigt, wobei zwischen der Korpusschiene und der Ausziehschiene ein Laufwagen mit lastübertragenden Wälzkörpern verschiebbar gelagert ist. An den Schienen sind Anschläge vorhanden, welche einen Fahrweg des Laufwagens in Längsrichtung der Schienen begrenzen. Die Laufwagen weisen an ihren Stirnseiten Federpuffer auf, die einen Anprall des Laufwagens an den Anschlägen in den Endstellungen des Laufwagens dämpfen. In der DE 20 2005 014 127 U1 ist eine weitere Schubladenausziehführung gezeigt, wobei zwischen der Korpusschiene und der Ladenschiene ein Wälzkörperkäfig verschiebbar gelagert ist. Der Wälzkörperkäfig ist in Richtung seiner Längsachse durch die Anordnung von Einschnitten federnd ausgebildet, sodass der Laufwagen bei einem Auftreffen auf einem an der Korpusschiene befindlichen Anschlag geräuschdämpfend abbremsbar ist. In EP 0 868 866 B1, a drawer pull-out guide with a carcass rail and a movably mounted pull-out rail is shown, wherein a carriage with load-transmitting rolling elements is mounted displaceably between the carcass rail and the pull-out rail. At the rails stops are present, which limit a travel path of the carriage in the longitudinal direction of the rails. The carriages have spring buffers on their front sides, which dampens an impact of the carriage on the stops in the end positions of the carriage. In DE 20 2005 014 127 U1 a further drawer pull-out is shown, wherein between the carcass rail and the drawer rail a rolling element cage is slidably mounted. The Wälzkörperkäfig is resiliently formed in the direction of its longitudinal axis by the arrangement of cuts, so that the carriage at a Impact on a located on the carcass rail stop can be braked noise-absorbing.
Nachteilig daran ist, dass die kinematische Energie bei Erreichen der jeweiligen Endlagen der Ausziehschiene praktisch ausschließlich von den Laufwagen aufgenommen wird, wodurch die Laufwagen erheblichen Belastungen ausgesetzt sind. Diese Belastungen können zu Deformationen oder gar zu einem Bruch der Laufwagen führen, insbesondere dann, wenn die Laufwagen aus Gründen einer kompakten Bauweise mit einer geringen Wandstärke aus Kunststoff ausgeführt sind. Eine zusätzliche Belastung der Laufwagen ist auch dann gegeben, wenn die Schubladenausziehführung eine kurze Nennlänge aufweist, weil dann die Ausziehschiene kurz unmittelbar nach dem Öffnen häufig mit viel Schwung in die vollständig ausgezogene Position gelangt und somit auch die Federpuffer des Laufwagens kraftvoll auf die Anschläge der Schienen auffahren. Auch in einem Missbrauchsfall, bei dem die Schublade mit übermäßiger manueller Krafteinwirkung in die Schließstellung oder Offenstellung katapultiert wird, wirken erhebliche Kräfte auf den Laufwagen, sodass die Gefahr einer Beschädigung des Laufwagens besteht. The disadvantage of this is that the kinematic energy is absorbed almost exclusively by the carriage when reaching the respective end positions of the pull-out, whereby the carriages are exposed to considerable loads. These loads can lead to deformation or even to a breakage of the carriage, especially if the carriages are designed for reasons of compact design with a small wall thickness made of plastic. An additional burden on the carriage is also given when the drawer extension has a short nominal length, because then the pull-out shortly after opening often comes with a lot of momentum in the fully extended position and thus the spring buffers of the carriage powerful on the attacks of the rails mount up. Even in a case of abuse in which the drawer is catapulted with excessive manual force in the closed position or open position, considerable forces act on the carriage, so there is a risk of damage to the carriage.
In der DE 10 2005 019 341 A1 ist im Ausführungsbeispiel gemäß den Figuren 15-19 eine Schubladenausziehführung gezeigt, wobei an der Korpusschiene und an der Ladenschiene jeweils Anschläge vorgesehen sind, welche bei Erreichen einer maximalen Auszugsbewegung der Ladenschiene miteinander zusammenwirken und damit eine weitere Auszugsbewegung der Ladenschiene verhindern. Aufgabe der vorliegenden Erfindung ist eine Schubladenausziehführung der eingangs erwähnten Gattung anzugeben, wobei die Gefahr einer Beschädigung des Laufwagens reduziert ist. In DE 10 2005 019 341 A1, a drawer pull-out guide is shown in the exemplary embodiment according to FIGS. 15-19, whereby stops are provided on the carcass rail and on the drawer rail which interact with each other when a maximum pull-out movement of the drawer rail is reached and thus a further pull-out movement of the drawer rail Prevent loading rail. Object of the present invention is to provide a drawer extension of the type mentioned, wherein the risk of damage to the carriage is reduced.
Dies wird erfindungsgemäß durch die Merkmale des Patentanspruchs 1 gelöst. Weitere vorteilhafte Ausgestaltungen der Erfindung sind in den abhängigen Unteransprüchen angegeben. This is achieved by the features of claim 1. Further advantageous embodiments of the invention are specified in the dependent subclaims.
Gemäß der Erfindung ist also vorgesehen, dass an der ersten Schiene ein Anschlag und dass an der zweiten Schiene ein Gegenanschlag angeordnet ist, wobei am Ende des maximalen Dämpfweges des Laufwagens der Anschlag der ersten Schiene und der Gegenanschlag der zweiten Schiene aneinander anschlagen und damit eine Bewegung der zweiten Schiene relativ zur ersten Schiene stoppen. Die vorliegende Erfindung beruht somit auf dem Grundgedanken, dass der Laufwagen beim Auftreffen auf das Begrenzungselement zunächst über den vorgegebenen maximalen Dämpfweg der Dämpfvorrichtung gedämpft wird, wobei bei Überschreitung einer vorgegebenen Kraftbeaufschlagung auf den Laufwagen der Anschlag und der Gegenanschlag der Schienen aneinander anschlagen und eine weitere Schienenbewegung stoppen, sodass eine weitere Krafteinwirkung auf den Laufwagen verhindert ist. According to the invention, it is thus provided that a stop is arranged on the first rail and that a counterstop is arranged on the second rail, wherein at the end of the maximum Dämpfweges of the carriage strike the stop of the first rail and the counter-stop of the second rail to each other and thus stop movement of the second rail relative to the first rail. The present invention is thus based on the basic idea that the carriage is damped when hitting the limiting element initially over the predetermined maximum Dämpfweg the damping device, which abuts when exceeding a predetermined application of force to the carriage of the stop and the counter-stop of the rails together and a further rail movement Stop, so that a further force on the carriage is prevented.
Auf diese Weise wird werden die übermäßigen Kräfte von den Schienen der Schubladenausziehführung aufgenommen, sodass der Laufwagen von diesen zusätzlichen Kräften unberührt bleibt. Der Laufwagen ist somit nach erfolgtem Dämpfungshub der Dämpfvorrichtung keinen zusätzlichen Belastungen ausgesetzt, die zu einer Deformation oder zu einem Bruch führen können. In this way, the excessive forces are absorbed by the rails of the drawer extension guide, so that the carriage remains untouched by these additional forces. The carriage is thus exposed after completion of the damping stroke of the damping device no additional loads that can lead to deformation or breakage.
Die Dämpfvorrichtung kann an einem stirnseitigen Ende des Laufwagens angeordnet sein, wobei die Dämpfvorrichtung gemäß einer ersten Ausführungsform zumindest eine am Laufwagen angeordnete Federzunge aufweisen kann, welche beim Auftreffen des Laufwagens auf das Begrenzungselement entgegen einer federnden Wirkung der Federzunge reversibel verbiegbar oder reversibel verformbar ist. Der maximale Dämpfweg ist also durch einen maximalen Komprimierweg der Federzunge vorgegeben, ohne dass dabei die Federzunge, der Laufwagen oder ein weiteres Bauteil beschädigt wird. The damping device may be arranged at a front end of the carriage, wherein the damping device according to a first embodiment may have at least one arranged on the carriage spring tongue, which is reversibly bendable or reversibly deformed upon impact of the carriage on the limiting element against a resilient action of the spring tongue. The maximum Dämpfweg is thus determined by a maximum Kompressierweg the spring tongue, without causing the spring tongue, the carriage or another component is damaged.
Gemäß einer weiteren Ausführungsform kann auch vorgesehen sein, dass die Dämpfvorrichtung des Laufwagens einen Fluiddämpfer aufweist, beispielsweise mit einer Kolben-Zylinder-Einheit, wie es in der EP 1 475 014 B1 gezeigt und beschrieben ist. Der maximale Dämpfweg ist in diesem Fall durch den maximal zulässigen Dämpfungshub der Kolben-Zylinder-Einheit vorgegeben. Da die Schließbewegung einer ausziehbaren Schiene der Schubladenausziehführung häufig durch eine gedämpfte Einzugsautomatik abgebremst wird, ist ein Schienenanschlag in der Schließstellung der Schubladenausziehführung nicht zwingend erforderlich. Somit kann es ausreichend sein, wenn die erste Schiene und die zweite Schiene zwischen einer Schließstellung und einer Offenstellung verfahrbar gelagert sind, wobei der Anschlag der ersten Schiene und der Gegenanschlag der zweiten Schiene in der Offenstellung aneinander anschlagen und damit eine fortgesetzte Auszugsbewegung der zweiten Schiene in Öffnungsrichtung verhindern. Eine erste Ausführungsform eines erfindungsgemäßen Möbels ist dadurch gekennzeichnet, dass das Möbel einen Möbelkorpus und eine Schublade aufweist, welche über eine Schubladenausziehführung der in Rede stehenden Art relativ zum Möbelkorpus verfahrbar gelagert ist, wobei die erste Schiene eine an einem Möbelkorpus zu befestigende Korpusschiene und die zweite Schiene eine an der Schublade befestigte Ladenschiene ist, wobei der Laufwagen zwischen der Korpusschiene und der Ladenschiene verfahrbar gelagert ist. According to a further embodiment, it can also be provided that the damping device of the carriage has a fluid damper, for example with a piston-cylinder unit, as shown and described in EP 1 475 014 B1. The maximum Dämpfweg is given in this case by the maximum allowable damping stroke of the piston-cylinder unit. Since the closing movement of an extendable rail of the drawer pull-out guide is often slowed down by a damped automatic retraction mechanism, a rail stop in the closed position of the drawer pull-out guide is not absolutely necessary. Thus, it may be sufficient if the first rail and the second rail are movably mounted between a closed position and an open position, wherein the stop of the first rail and the counter-stop of the second rail abut each other in the open position and thus a continued extension movement of the second rail in Prevent opening direction. A first embodiment of a piece of furniture according to the invention is characterized in that the piece of furniture has a furniture body and a drawer which is movably supported relative to the furniture body via a drawer pull-out guide of the type in question, wherein the first rail has a cabinet rail to be fastened to a furniture carcass and the second Rail is a drawer rail attached to the drawer, the carriage is movably mounted between the carcass rail and the drawer rail.
Eine zweite Ausführungsform eines erfindungsgemäßen Möbels ist dadurch gekennzeichnet, dass das Möbel einen Möbelkorpus und eine Schublade aufweist, welche über eine Schubladenausziehführung der in Rede stehenden Art relativ zum Möbelkorpus verfahrbar gelagert ist, wobei die erste Schiene eine am Möbelkorpus befestigte Korpusschiene und die zweite Schiene eine Mittelschiene ist, welche zwischen der Korpusschiene und einer an der Schublade befestigten Ladenschiene verfahrbar gelagert ist, wobei der Laufwagen zwischen der Korpusschiene und der Mittelschiene verfahrbar gelagert ist. A second embodiment of a piece of furniture according to the invention is characterized in that the piece of furniture has a furniture body and a drawer which is movably supported relative to the furniture body via a drawer pull-out guide of the type in question, the first rail comprising a cabinet rail fastened to the furniture body and the second rail a Middle rail is which is movably mounted between the carcass rail and a drawer rail fastened to the drawer, wherein the carriage is movably mounted between the carcass rail and the center rail.

Fig. 1 zeigt ein Möbel 1 mit einem schrankförmigen Möbelkorpus 2, wobei Schubladen 3 über Schubladenausziehführungen 4 relativ zum Möbelkorpus 2 verfahrbar gelagert sind. Die Schubladen 3 weisen jeweils eine Frontblende 5, einen Schubladenboden 6, Schubladenseitenwände 7 und eine Rückwand 8 auf. Die Schubladenausziehführungen 4 umfassen jeweils eine Schiene 9 (Korpusschiene), welche über Befestigungsabschnitte 12a, 12b stationär am Möbelkorpus 2 zu befestigen ist, eine relativ zur Schiene 9 verschiebbar gelagerte zweite Schiene 10 (Ladenschiene), welche mit der Schubladenseitenwand 7 verbunden oder zu verbinden ist, sowie eine erste Schiene 1 1 (Mittelschiene), welche zur Realisierung eines Vollauszuges der Schublade 3 zwischen der Schiene 9 und der zweiten Schiene 10 verfahrbar gelagert ist. Aus Gründen der Einfachheit wird in der vorliegenden Beschreibung die Mittelschiene als erste Schiene 1 1 und die Ladenschiene als zweite Schiene 10 bezeichnet. Selbstverständlich ist aber auch klar, dass die Korpusschiene als erste Schiene und die Mittelschiene als zweite Schiene angesehen werden kann. Fig. 1 shows a piece of furniture 1 with a cabinet-shaped furniture body 2, wherein drawers 3 are movably mounted on Schubladenausziehführungen 4 relative to the furniture body 2. The drawers 3 each have a front panel 5, a drawer bottom 6, drawer side walls 7 and a rear wall 8. The drawer extension guides 4 each comprise a rail 9 (carcass rail), which is to be fastened to the furniture carcass 2 via fixing sections 12a, 12b, a second rail 10 (drawer rail) displaceably mounted relative to the rail 9 and connected or to be connected to the drawer side wall 7 , And a first rail 1 1 (middle rail), which is mounted to realize a full extension of the drawer 3 between the rail 9 and the second rail 10 movable. For reasons of simplicity, in the present description the middle rail is referred to as the first rail 1 1 and the drawer rail as the second rail 10. Of course, it is also clear that the carcass rail can be regarded as a first rail and the center rail as a second rail.
Fig. 2a zeigt eine teilweise aufgebrochene Schubladenausziehführung 4 in einer Offenstellung mit der am Möbelkorpus 2 zu befestigenden Schiene 9 (Korpusschiene), wobei zwischen der Schiene 9 und der zweiten Schiene 10 eine auszugsverlängernde erste Schiene 1 1 (Mittelschiene) verschiebbar gelagert ist. Mit der Schiene 9 sind Befestigungsabschnitte 12a und 12b verbunden, durch welche die Schubladenausziehführung 4 am Möbelkorpus 2 zu montieren ist. Fig. 2a shows a partially broken Schubladenausziehführung 4 in an open position with the furniture body 2 to be fastened rail 9 (carcass rail), between the rail 9 and the second rail 10 an aussverlängernde first rail 1 1 (middle rail) is slidably mounted. With the rail 9 are Attachment sections 12a and 12b are connected, through which the drawer extension guide 4 is to be mounted on the furniture body 2.
Fig. 2b zeigt den in Fig. 2a eingerahmten Bereich in einer vergrößerten Ansicht. Der Befestigungsabschnitt 12a weist mehrere Löcher 13 zum Durchtritt von Schrauben auf, durch die eine Befestigung am Möbelkorpus 2 erfolgt. Die zweite Schiene 10 ist teilweise aufgebrochen dargestellt, sodass der Laufwagen 16 mit darin gelagerten Wälzkörpern 17 ersichtlich ist. An einem stirnseitigen Ende des Laufwagens 16 ist eine Dämpfvorrichtung 18 angeordnet, welche im gezeigten Ausführungsbeispiel als Federpuffer mit zumindest einer Federzunge 18a ausgebildet ist. Vorzugsweise ist vorgesehen, dass die Federzunge 18a zusammen mit dem Laufwagen 16 aus einem einstückigen Kunststoffteil gespritzt ist. An einem hinteren Endbereich der zweiten Schiene 10 ist ein Begrenzungselement 15 angeordnet, welches einen Fahrweg des Laufwagens 16 in Ausziehrichtung 19 begrenzt. Das Begrenzungselement 15 ist in der gezeigten Figur zusammen mit der zweiten Schiene 10 einstückig ausgebildet und kann als eine von der zweiten Schiene 10 abgebogene Lasche ausgebildet sein. Die Federzunge 18a ist beim Auftreffen des Laufwagens 16 auf das Begrenzungselement 15 entgegen einer federnden Wirkung der Federzunge 18a reversibel verbiegbar oder reversibel verformbar und dämpft auf diese Weise einen Anprall des Laufwagens 16 auf das Begrenzungselement 15. Anstelle einer oder mehreren Federzungen 18a kann als Dämpfvorrichtung 18 auch ein Lineardämpfer, beispielsweise mit einer Kolben-Zylinder- Einheit, am oder im Laufwagen 16 angeordnet sein. Am hinteren Ende der zweiten Schiene 10 ist ein Stift 14 angeordnet, welcher sich beabstandet zu einer Oberseite der zweiten Schiene 10 in einer horizontalen Richtung in Längsrichtung der zweiten Schiene 10 erstreckt. Dieser Stift 14 greift in Montagelage in eine in der Rückwand 8 (Fig. 1 ) angeordnete Bohrung ein und verhindert so eine unerwünschte Lageveränderung des hinteren Endbereiches der Schublade 3 relativ zur zweiten Schiene 10. FIG. 2b shows the area framed in FIG. 2a in an enlarged view. The attachment portion 12a has a plurality of holes 13 for the passage of screws through which attachment to the furniture body 2 takes place. The second rail 10 is shown partially broken, so that the carriage 16 is mounted therein with rolling elements 17 can be seen. At a front end of the carriage 16, a damping device 18 is arranged, which is formed in the illustrated embodiment as a spring buffer with at least one spring tongue 18a. It is preferably provided that the spring tongue 18a is sprayed together with the carriage 16 from a one-piece plastic part. At a rear end region of the second rail 10, a limiting element 15 is arranged, which limits a travel path of the carriage 16 in the withdrawal direction 19. The limiting element 15 is integrally formed in the figure shown together with the second rail 10 and may be formed as a bent from the second rail 10 tab. The spring tongue 18a is reversibly bendable or reversibly deformable upon impact of the carriage 16 on the limiting element 15 against a resilient action of the spring tongue 18a and dampens in this way, an impact of the carriage 16 on the limiting element 15. Instead of one or more spring tongues 18a can be used as a damping device 18th Also, a linear damper, for example with a piston-cylinder unit, be arranged on or in the carriage 16. At the rear end of the second rail 10, a pin 14 is arranged, which extends at a distance to an upper side of the second rail 10 in a horizontal direction in the longitudinal direction of the second rail 10. This pin 14 engages in mounting position in a in the rear wall 8 (Fig. 1) arranged bore, thus preventing an undesirable change in position of the rear end portion of the drawer 3 relative to the second rail 10th
Fig. 3a zeigt eine in Bezug zu Fig. 2b fortgesetzte Bewegung der zweiten Schiene 10 in Ausziehrichtung 19, wobei die Federzunge 18a der Dämpfvorrichtung 18 am Begrenzungselement 15 anliegt. In Fig. 3b ist der maximale Dämpfweg 23 (Fig. 4b) der Dämpfvorrichtung 18 erreicht, wobei das freie Ende der Federzunge 18a am Laufwagen 16 anliegt und damit maximal verformt oder verbogen ist. In dieser Stellung des Laufwagens 16 schlagen ein Anschlag 20 der ersten Schiene 1 1 und ein Gegenanschlag 21 der zweiten Schiene 10 aneinander an und stoppen eine Bewegung der zweiten Schiene 10 relativ zur ersten Schiene 1 1 , wie es in den nachfolgenden Figuren gezeigt und beschrieben ist. FIG. 3 a shows a movement of the second rail 10 in the pull-out direction 19 continued in relation to FIG. 2 b, wherein the spring tongue 18 a of the damping device 18 bears against the limiting element 15. In Fig. 3b, the maximum Dämpfweg 23 (Fig. 4b) of the damping device 18 is reached, wherein the free end of the spring tongue 18a abuts the carriage 16 and thus is maximally deformed or bent. In this position of the Carriage 16 strike a stop 20 of the first rail 1 1 and a counter-stop 21 of the second rail 10 to each other and stop movement of the second rail 10 relative to the first rail 1 1, as shown and described in the following figures.
Fig. 4a-4c zeigen das Zusammenwirken der Dämpfvorrichtung 18 des Laufwagens 16 mit dem Begrenzungselement 15 der zweiten Schiene 10 sowie das Zusammenwirken des Anschlages 20 der zweiten Schiene 10 mit dem Gegenanschlag 21 der ersten Schiene 1 1 in zeitlichen Abfolgen. Das Begrenzungselement 15 und der Anschlag 20 sind fest mit der zweiten Schiene 10 verbunden, während der Gegenanschlag 21 fest mit der ersten Schiene 1 1 in Verbindung steht. Die zweite Schiene 10 wird in Ausziehrichtung 19 solange bewegt, bis die zumindest eine Federzunge 18 der Dämpfvorrichtung 18 des Laufwagens 16 auf das Begrenzungselement 15 der zweiten Schiene 10 auftrifft (Fig. 4b), wobei der von der zweiten Schiene 10 quer abstehende Anschlag 20 und der von der ersten Schiene 1 1 quer abstehende Gegenanschlag 21 noch voneinander beabstandet sind. Durch eine Verbiegung oder Verformung der Federzunge 18a ist eine Bewegung des Laufwagens 16 über einen vorgegebenen Dämpfweg 23 dämpfbar, nämlich solange, bis das freie Ende der Federzunge 18a durch Anschlagen am Laufwagen 16 maximal verformt oder verbogen wird. Bei Erreichen des maximalen Dämpfungshubes der Dämpfvorrichtung 18 schlagen der Anschlag 20 der zweiten Schiene 10 und der Gegenanschlag 21 der ersten Schiene 1 1 aneinander an (Fig. 4c) und verhindern damit eine weitere Bewegung der zweiten Schiene 10 relativ zur ersten Schiene 1 1 . Durch das Zusammenwirken des Anschlages 20 und des Gegenanschlages 21 wird der Laufwagen 16 von zusätzlichen Kräften entlastet, sodass die Gefahr einer unerwünschten Verformung oder ein Bruch des Laufwagens 16 verhindert ist. Dabei kann vorgesehen sein, dass das Zusammenwirken der Federzunge 18a mit dem Begrenzungselement 15 und das Zusammenwirken des Anschlages 20 mit dem Gegenanschlag 21 für eine Person zwei unterscheidbare Geräusche verursachen. Der durch den Anschlag 20 und den Gegenanschlag 21 gebildete Schienenanschlag ist nämlich härter als der durch die Dämpfvorrichtung 18 und das Begrenzungselement 15 gebildete Laufwagenanschlag ausgebildet. Dies kann beispielsweise dadurch erreicht werden, indem der Anschlag 20 und der Gegenanschlag 21 jeweils aus einem metallischen Material gebildet sind und damit ein akustisch hartes Warngeräusch verursachen. Somit wird ein Großteil der Energie über diese„Hartanschläge" und nicht über den Laufwagen 16 abgebaut. 4a-4c show the interaction of the damping device 18 of the carriage 16 with the limiting element 15 of the second rail 10 and the interaction of the stop 20 of the second rail 10 with the counter-stop 21 of the first rail 1 1 in time sequences. The limiting element 15 and the stop 20 are fixedly connected to the second rail 10, while the counter-stop 21 is firmly connected to the first rail 1 1 in connection. The second rail 10 is moved in the pull-out direction 19 until the at least one spring tongue 18 of the damping device 18 of the carriage 16 strikes the limiting element 15 of the second rail 10 (FIG. 4 b), the stop 20 projecting transversely from the second rail 10 of the first rail 1 1 transversely projecting counter-stop 21 are still spaced apart. By bending or deformation of the spring tongue 18a, a movement of the carriage 16 via a predetermined Dämpfweg 23 can be damped, namely, until the free end of the spring tongue 18a is maximally deformed or bent by striking the carriage 16. Upon reaching the maximum damping stroke of the damping device 18 strike the stop 20 of the second rail 10 and the counter-stop 21 of the first rail 1 1 to each other (Fig. 4c) and thus prevent further movement of the second rail 10 relative to the first rail 1 first The interaction of the stop 20 and the counter-stop 21 of the carriage 16 is relieved of additional forces, so that the risk of undesirable deformation or breakage of the carriage 16 is prevented. It can be provided that the interaction of the spring tongue 18a with the limiting element 15 and the interaction of the stop 20 with the counter-stop 21 for a person cause two distinguishable noises. The rail stop formed by the stop 20 and the counter-stop 21 is namely harder than the formed by the damping device 18 and the limiting element 15 carriage stop formed. This can for example be achieved by the stop 20 and the counter-stop 21 are each formed of a metallic material and thus a cause a hard acoustic warning sound. Thus, much of the energy is dissipated via these "hard stops" and not via the carriage 16.
Die Schubladenausziehführung 4 weist ferner eine Zwangssteuerung 22 auf, durch die eine Bewegung des Laufwagens 16 relativ zu einem weiteren Laufwagen 16a (welcher zwischen der am Möbelkorpus 2 zu befestigenden Schiene 9 und der ersten Schiene 1 1 verschiebbar gelagert ist) und/oder zumindest eine Bewegung des Laufwagens 16 relativ zur ersten Schiene 1 1 und zweiten Schiene 10 entsprechend einem vorgegebenen Bewegungsmuster steuerbar ist. Im gezeigten Ausführungsbeispiel umfasst die Zwangssteuerung 22 ein an der ersten Schiene 1 1 drehbar gelagertes Zahnrad, welches einerseits mit einer Verzahnung des oberen Laufwagens 16 und andererseits mit einer Verzahnung des unteren Laufwagens 16a zusammenwirkt. Alternativ kann die Zwangssteuerung 22 - wie an sich bekannt - ein Reibrad aufweisen, welches einerseits mit einer ersten Lauffläche der Schiene 9 und andererseits mit einer zweiten Lauffläche der zweiten Schiene 10 zusammenwirkt. The drawer pull-out guide 4 also has a positive control 22, by which a movement of the carriage 16 relative to another carriage 16a (which is slidably mounted between the rail 9 to be fastened to the furniture body 2 and the first rail 1 1) and / or at least one movement of the carriage 16 relative to the first rail 1 1 and second rail 10 is controllable according to a predetermined movement pattern. In the illustrated embodiment, the positive control 22 comprises a rotatably mounted on the first rail 1 1 gear, which cooperates on the one hand with a toothing of the upper carriage 16 and on the other hand with a toothing of the lower carriage 16a. Alternatively, the positive control 22 - as known per se - have a friction wheel, which cooperates on the one hand with a first running surface of the rail 9 and on the other hand with a second running surface of the second rail 10.
