Description

Die Erfindung bezieht sich auf eine Schubkasten-Auszugvorrichtung mit einer an einem Möbelstück feststehend angebrachten Aussenschiene, einer an dem Schubkasten seitlich angebrachten Schubschiene und einer Mittelschiene, wobei zur Gleichlaufsteuerung an den Innenflächen der Aussenschiene und der Schubschiene je eine sich über deren Gesamtlänge erstreckende Zahnstange vorgesehen ist, in welche ein einziges im mittleren Bereich der Mittelschiene gelagertes Zahnrad beiderseitig eingreift, wobei ferner die Aussen- und Schubschiene derart ausgebildet sind, dass die Längsränder der Mittelschiene in diese gleitfähig hineinragen, wobei Anschläge zur Wegbegrenzung des Auszugs vorgesehen sind.The invention relates to a drawer pull-out device with an outer rail fixed to a piece of furniture, a slide rail attached to the side of the drawer and a central rail, with a rack extending over its entire length being provided on the inner surfaces of the outer rail and the slide rail for synchronous control , into which a single gearwheel mounted in the central region of the central rail engages on both sides, the outer and push rails also being designed such that the longitudinal edges of the central rail protrude into it in a slidable manner, stops being provided to limit the path of the pull-out.

Aus dem DE-UM Nr. 78.16727 ist bereits eine Schubkasten-Auszugvorrichtung bekannt. Derartige Auszugvorrichtungen werden in grossem Umfang zur leichtgängigen und verschleissarmen Führung von Schubkästen in Möbeln eingesetzt. Ihre teleskopartige Funktion erlaubt es, den Schubkasten voll zugänglich aus dem Möbelstück herauszuziehen. Bei der bekannten Schubkasten-Vollauszugschiene besteht die Mittelschiene aus zwei spiegelbildlich symmetrischen Hälften, die zu einem kastenförmigen Gebilde zusammengesetzt sind, und zwar bestehen die beiden Hälften aus Metallschienen, die in besonderer Weise profiliert und stellenweise untereinander mit Hilfe von Hohlnieten verbunden sind. Die Hohlnieten müssen in der Praxis im mittleren Bereich dieser profilierten Metallschienen vorgesehen sein. Aus diesem Grundesind sowohl an der Korpusschiene, als auch an der Schubschiene je zwei seitlich versetzte Zahnstangen vorgesehen, in die entsprechend auch je zwei Zahnräder eingreifen. Zum Zusammenhalt der Schienen untereinander sind in den Hohlkammern der Mittelschiene insgesamt sechzehn Rollen drehbar gelagert, die in im Querschnitt dreieckigen Führungsrillen der Korpusschiene und der Schubschiene laufen. Trotz des Bestrebens, eine einfache und kostengünstige Bauweise zu erzielen, ergibt sich bei der bekannten Vorrichtung immer noch ein verhältnismässig hoher Aufwand, der einmal in dem komplizierten Aufbau der Mittelschiene und den erforderlichen, insgesamt vier Zahnstangen zu sehen ist. Zum anderen müssen die insgesamt sechzehn Rollen gelagert werden, um eine Rollführung der Schienen untereinander zu erhalten. Es hat sich aber in der Praxis erwiesen, dass diese Rollführung nicht nur sehr aufwendig, sondern vor allem auch unsicher ist, denn schon bei geringem Schrägziehen des Schubkastens springen die Rollen aus den dreieckigen Führungsrillen heraus und stellen die weitere Bedienbarkeit in Frage. Die Folge ist vielfach eine Beschädigung oder Zerstörung der Schubkasten-Auszugvorrichtung.A drawer pull-out device is already known from DE-UM No. 78.16727. Such pull-out devices are widely used for smooth and low-wear guidance of drawers in furniture. Their telescopic function allows the drawer to be pulled out of the piece of furniture in a fully accessible manner. In the known drawer full extension rail, the middle rail consists of two mirror-symmetrical halves, which are put together to form a box-shaped structure, namely the two halves consist of metal rails, which are profiled in a special way and connected in places with the help of hollow rivets. In practice, the hollow rivets must be provided in the central area of these profiled metal rails. For this reason, two laterally offset toothed racks are provided both on the body rail and on the push rail, into which two toothed wheels respectively engage. In order to hold the rails together, a total of sixteen rollers are rotatably mounted in the hollow chambers of the middle rail, which run in guide grooves of triangular cross section of the body rail and the push rail. Despite the endeavor to achieve a simple and inexpensive construction, the known device still results in a relatively high outlay, which can be seen in the complicated structure of the center rail and the required four racks in total. On the other hand, the total of sixteen rollers have to be stored in order to ensure that the rails roll together. In practice, however, it has been shown that this roller guide is not only very complex, but above all unsafe, because even when the drawer is pulled slightly at an angle, the rollers jump out of the triangular guide grooves and question its further operability. The result is often damage or destruction of the drawer puller.

Aus der CH-A Nr. 494005 ist ferner eine Vollauszugvorrichtung bekannt, bei welcher die beiden Längsränder der Aussenschiene und die Längsränder der Schubschiene U-förmig geformt sind, derart, dass die freien Schenkel der U-förmigen Ränder mit Abstand und parallel zu den Schieneninnenflächen verlaufend nach innen gerichtet sind, wobei die Mittelschiene als massiver, einstückiger Körper ausgebildet ist, dessen Längskanten leistenartige Vorsprünge aufweisen, die ihrerseits in die U-förmigen Ränder der Aussenschiene und der Schubschiene gleitfähig hineinragen. Bei dieser Vollauszugvorrichtung ist jedoch keine Gleichlaufsteuerung vorgesehen. Daraus ergibt sich der Nachteil, dass die zu beiden Seiten beispielsweise einer Abstellplatte angeordneten Führungsschienen beim Herausziehen und Wiedereinschieben der Abstellplatte unterschiedlich bewegt werden, so dass es, wie die Praxis bestätigt, zu Verkantungen und einseitigen Hemmungen kommen kann. Es kommt hinzu, dass auch die Montage der auf den ersten Blick recht einfach erscheinenden Führungsschienen mit Schwierigkeiten verbunden ist. Dies liegt vor allem gerade an der besonderen Ausbildung der Anschläge zur Wegbegrenzung durch besondere Bolzen und durch die in Längsnuten eingesetzten Stücke.From CH-A No. 494005 a full extension device is also known in which the two longitudinal edges of the outer rail and the longitudinal edges of the push rail are U-shaped, such that the free legs of the U-shaped edges are spaced apart and parallel to the rail inner surfaces are directed inwards, the middle rail being designed as a solid, one-piece body, the longitudinal edges of which have strip-like projections which in turn protrude into the U-shaped edges of the outer rail and the push rail. However, no synchronization control is provided in this full extension device. This results in the disadvantage that the guide rails arranged on both sides of a storage plate, for example, are moved differently when the storage plate is pulled out and pushed back in, so that, as practice has confirmed, tilting and one-sided inhibitions can occur. In addition, the assembly of the guide rails, which at first glance appear to be very simple, is also difficult. This is mainly due to the special design of the stops to limit the travel using special bolts and the pieces used in the longitudinal grooves.

Den beiden vorerläuterten bekannten Auszugvorrichtungen haften also erhebliche Nachteile an, die im wesentlichen auch bestehen bleiben würden, wenn man Einzelmerkmale der bekannten Vorrichtung der CH-A Nr. 494005, z.B. die Schienenkonstruktion, auf die bekannte Vorrichtung nach dem DE-U Nr. 78.16727 übertragen wollte.The two above-mentioned known pull-out devices therefore have considerable disadvantages, which would essentially also remain if individual features of the known device of CH-A No. 494005, e.g. the rail construction wanted to transfer to the known device according to DE-U No. 78.16727.

In jedem Falle sind dann auf beiden Seiten je zwei Zahnstangen und demgemäss zwei Zahnräder erforderlich. Die Verwendung von je zwei Zahnstangen bringt aber ausser den weiter oben aufgeführten Nachteilen noch einen weiteren wesentlichen Nachteil mit sich. In der Praxis werden sich nämlich die Schienen im ausgezogenen und belasteten Zustand immer ein wenig durchbiegen. Die neutrale Biegelinie befindet sich aber bei symmetrischen Profilen in der Mitte des Profils. Wenn man also zwei Zahnstangen verwenden muss, so befinden sich diese beiden Zahnstangen jede mit Abstand von der neutralen Biegelinie. Dadurch gibt es Unterschiede im Eingriff der beiden Zahnräder, so dass es auch zwischen den beiden Zahnrädern und den beiden Zahnstangen zu Verklemmungen und auf die Dauer zu erhöhtem Verschleiss kommen kann.In any case, two racks and two gears are required on both sides. However, the use of two racks each has another major disadvantage in addition to the disadvantages listed above. In practice, the rails will always bend a little when pulled out and under load. The neutral bending line is in the middle of the profile for symmetrical profiles. So if you have to use two racks, these two racks are each at a distance from the neutral bending line. As a result, there are differences in the engagement of the two gear wheels, so that there can also be jams between the two gear wheels and the two toothed racks and, in the long run, increased wear.

Ferner ist aus der US-A Nr. 3975063 eine Auszugvorrichtung bekannt, welche im wesentlichen aus einer Aussen-, einer Mittel- und einer Schubschiene besteht, wobei an den Innenflächen der Aussen- und Schubschiene, und zwar im mittleren Bereich Zahnstangen vorgesehen sind. Diese Zahnstangen bestehen jedoch aus U-förmigen Profilen, und die Zähne sind an den freien längslaufenden Kanten vorgesehen, so dass die Zahnreihen jeder Zahnstange paarweise und mit Abstand voneinander vorhanden sind. In die insgesamt vier Zahnreihen greift eine Zahnwalze ein, die in der Mittelschiene angeordnet ist. Die Ränder der Schienen greifen ineinander und werden mittels zylinderförmigen Stücken zusammengehalten. Zusätzlich sind Kugeln als Kugellager vorgesehen. Abgesehen von dem recht komplizierten und aufwendigen Aufbau, muss man auch bei dieser bekannten Auszugvorrichtung erwarten, dass ein Klemmen oder gar eine Beschädigung von Zähnen der Zahnstangen eintritt, wenn eine mehr oder weniger grosse Biegebelastung auf die Schienen einwirkt.Further 3975063 an extraction apparatus is known from US-A No known which essentially consists of an outer -., A middle and a push rail, said racks are provided on the inner surfaces of the outer and push rail, and that in the central region. However, these racks consist of U-shaped profiles, and the teeth are provided on the free longitudinal edges, so that the rows of teeth of each rack are in pairs and spaced apart. A toothed roller, which is arranged in the central rail, engages in the four rows of teeth. The edges of the rails interlock and are held together by means of cylindrical pieces. Balls are also provided as ball bearings. Apart from the quite complicated and complex structure, you also have to be with this Known pull-out device expect that the teeth of the racks become jammed or even damaged if the rails are subjected to a greater or lesser bending load.

Aus der FR-A Nr. 522152 ist eine anderartig aufgebaute Vorrichtung zur Rollenführung von Schubkästen bekannt, wobei eine der Befestigung dienende Grundschiene mit nach aussen über die Längsränder hinausragenden Pratzen versehen ist. Die Pratzen weisen Bohrungen auf, durch die Befestigungsschrauben hindurchgeführt werden können.From FR-A No. 522152 a differently constructed device for the roller guidance of drawers is known, wherein a base rail serving for fastening is provided with claws projecting outwards beyond the longitudinal edges. The claws have holes through which fastening screws can be passed.

Bei der Erfindung wird von einer zu Anfang erläuterten Schubkasten-Auszugvorrichtung ausgegangen, welche aus der FR-A Nr. 2433917 bekannt ist. Hierbei befinden sich die Zahnstangen an den waagerechten einander zugekehrten Flächen der Aussenschiene und Schubschiene, so dass auch hier bei Biegebelastung erhebliche Klemmwirkungen und Beschädigungen an den Zähnen auftreten können, weil sich die Zahnstangen mitverhältnismässig grossem Abstand von der mittleren Biegelinie befinden. Ferner sei bemerkt, dass an der einen vertikalen Längsfläche der Mittelschiene ein U-Profil befestigt ist, so dass hierdurch die Längsränder gebildet werden, die gleitfähig in die Aussen- und Schubschiene hineinragen.The invention is based on a drawer pull-out device explained at the beginning, which is known from FR-A No. 2433917. Here, the racks are located on the horizontal facing surfaces of the outer rail and push rail, so that here too, considerable bending effects and damage to the teeth can occur under bending stress, because the racks are at a relatively large distance from the center bending line. Furthermore, it should be noted that a U-profile is fastened to the one vertical longitudinal surface of the central rail, so that the longitudinal edges are formed thereby, which protrude into the outer and sliding rails in a sliding manner.

Aufgabe der Erfindung ist es, eine Schubkasten-Auszugvorrichtung zu schaffen, welche bei einfacher Gestaltung eine Gleichlaufsteuerung ermöglicht, bei der ein Klemmen oder Beschädigen der Zähne der Zahnstangen oder des Zahnrades vermieden wird.The object of the invention is to provide a drawer pull-out device which, with a simple design, enables synchronization control in which jamming or damage to the teeth of the toothed racks or the gearwheel is avoided.

Die gestellte Aufgabe wird gelöst durch die Kombination folgender Merkmale, nämlich dass sich die Zahnstangen im mittleren Bereich der Aussen- und Schubschiene befinden, dass die beiden Längsränder der Aussenschiene und die Längsränder der Schubschiene U-förmig geformt sind, derart, dass die freien Schenkel der U-förmigen Ränder mit Abstand und parallel zu den Schieneninnenflächen verlaufend nach innen gerichtet sind, dass die Mittelschiene als massiver, einstük- kiger Körper ausgebildet ist, dessen Längskanten leistenartige Vorsprünge aufweisen, welche in die U-förmigen Ränder der Aussen- und der Schubschiene gleitfähig hineinragen, dass die Anschläge zur Wegbegrenzung des Auszuges von je zwei in der Aussen- und der Schubschiene sitzenden Bolzen gebildet sind, die aus den Innenflächen der Aussen- und Schubschiene hervorragen und in je zwei längsverlaufende Nuten der Mittelschiene hineingreifen, dass die Nuten mit kleinem Abstand von den Stirnflächen der Mittelschiene enden, und dass die Aussenschiene mit nach aussen über die Längsränder hinausragenden Pratzen mit Zapfen versehen ist.The object is achieved by the combination of the following features, namely that the racks are located in the central region of the outer and slide rails, that the two longitudinal edges of the outer rail and the longitudinal edges of the slide rail are U-shaped, such that the free legs of the U-shaped edges spaced from and oriented parallel to the rail inside surfaces extending inwardly are that the central rail is designed as a solid, one t ük- kiger body whose longitudinal edges have strip-like projections which form U-into the edges of the outer and the The slide rail protrudes so that the stops to limit the pull-out are formed by two bolts each in the outer and the slide rail, which protrude from the inner surfaces of the outer and slide rail and engage in two longitudinal grooves of the middle rail so that the grooves also end a small distance from the end faces of the center rail, and that the outer rail is provided with pins which protrude outwards beyond the longitudinal edges.

  • 2 shows a side view of the drawer pull-out device according to FIG. 1,
  • 3 shows a plan view of the drawer pull-out device according to FIG. 1, but on the side facing the piece of furniture,
  • 4 is a partial plan view corresponding to FIG. 1, but in the fully extended position,

Das in den Fig. 1 bis 6 dargestellte Ausführungsbeispiel der erfindungsgemässen Schubkasten-Auszugvorrichtung weist eine Aussenschiene 1 auf, die mittels vorzugsweise vier Zapfen 15, 16, 17 und 18 an dem Möbelstück 44 (Fig. 5) befestigt ist. Von wesentlicher Bedeutung ist, dass die Zapfen 15 bis 18, die zweckmässigerweise aus massivem Material einstückig mit der Aussenschiene 1 ausgebildet sind, an nach aussen über die Längsränder der Aussenschiene hinausragenden Pratzen 11, 12, 13 und 14 angeordnet sind. Bei dieser besonderen Befestigungsart der Aussenschiene 1 an dem Möbelstück 44 ergibt sich eine besonders biegesichere Halterung, weil die weit aussen liegenden Zapfen in bezug auf die mittlere Biegelinie der Aussenschiene ein einer Biegung entgegengesetztes Moment erzeugen. Ein weiterer wesentlicher Vorteil der Anordnung der Zapfen 15 bis 18 an den aussenliegenden Pratzen 11 bis 14 besteht darin, dass beim Einsatz der Schubkasten-Auszugvorrichtung diese Pratzen frei zugänglich sind, so dass man die Zapfen leicht in die im Möbelstück 44 vorgesehenen Bohrungen 46 und 47 einschlagen kann, ohne Gefahr zu laufen, dass die Schubkasten-Auszugvorrichtung an irgendwelchen Stellen der Schienen selbst durch das Einschlagen beschädigt wird.The exemplary embodiment of the drawer pull-out device according to the invention shown in FIGS. 1 to 6 has an outer rail 1 which is fastened to the piece of furniture 44 (FIG. 5) by means of preferably four pins 15, 16, 17 and 18. It is essential that the pins 15 to 18, which are expediently formed from solid material in one piece with the outer rail 1, are arranged on claws 11, 12, 13 and 14 projecting outwards beyond the longitudinal edges of the outer rail. This particular type of fastening of the outer rail 1 to the piece of furniture 44 results in a particularly flexurally secure holder because the pins located far outside produce a moment opposite to a bend with respect to the middle bending line of the outer rail. Another significant advantage of the arrangement of the pins 15 to 18 on the external claws 11 to 14 is that when using the drawer pull-out device, these claws are freely accessible, so that the pins can easily be inserted into the holes 46 and 47 provided in the piece of furniture 44 can knock in without running the risk of the drawer puller being damaged at any point on the rails itself by the knocking in.

Die Schubkasten-Auszugvorrichtung weist weiterhin eine Schubschiene 2 auf, die mit Ausnahme der erläuterten Pratzen und Zapfen symmetrisch zur Aussenschiene 1 ausgebildet ist. Diese Schubschiene 2 wird, wie Fig. 5 veranschaulicht, in eine Schubkastenrille 49 bzw. Nute mit rechtekkigem Querschnitt eingeschoben und gehalten. Für die Befestigung der Schubschiene an dem Schubkasten 45 genügt daher ein einziger Zapfen 25, der zweckmässigerweise als Hohlzapfen oder Spreizzapfen ausgebildet ist. Der Hohlzapfen 25 ist etwa mit dem gleichen Abstand von dem einen stirnseitigen Ende der Schubschiene entfernt angeordnet wie die Zapfen 17,18 der Aussenschiene 1.The drawer pull-out device furthermore has a drawer rail 2 which, with the exception of the claws and pins explained, is formed symmetrically to the outer rail 1. 5, this slide rail 2 is inserted and held in a drawer groove 49 or groove with a rectangular cross section. A single pin 25, which is expediently designed as a hollow pin or expansion pin, is therefore sufficient for fastening the slide rail to the drawer 45. The hollow pin 25 is arranged at approximately the same distance from the one end of the slide rail as the pins 17, 18 of the outer rail 1.

Zur Materialersparnis und vor allem, um eine bessere Anlage der Aussenschiene 1 an dem Möbelstück 44 und der Schubschiene 2 an der Innenfläche der Schubkastenrille 49 zu erreichen, sind bei der Aussenschiene 1 Längsrillen 3, 4 vorgesehen, die sich nahezu über die gesamte Schienenlänge erstrecken. Ferner sind Längsrillen 5, 6 und 7, 8 vorgesehen, die aber in dem mittleren Bereich der Aussenschiene durch ein massives Schienenteil unterbrochen sind, so dass hier Metallbolzen 9, 10 eingesetzt sind, die in Verbindung mit den Nuten 29,30 einer Mittelschiene 28 als Anschläge für die Begrenzung des Auszuges nach beiden Seiten hin dienen.To save material and, above all, to achieve better contact of the outer rail 1 with the piece of furniture 44 and the push rail 2 on the inner surface of the drawer groove 49, longitudinal grooves 3, 4 are provided in the outer rail 1, which extend almost over the entire length of the rail. Furthermore, longitudinal grooves 5, 6 and 7, 8 are provided, which, however, are interrupted in the central region of the outer rail by a solid rail part, so that here metal bolts 9, 10 are used, which in connection with the grooves 29, 30 of a central rail 28 Stops for serve to limit the extension on both sides.

Entsprechend der Aussenschiene 1 ist auch die Schubschiene 2 mit Längsrillen 19, 20 sowie unterbrochenen Längsrillen 21,22 und 23, 24 versehen. Die Letzteren erhalten noch einmal eine Unterbrechung für eine Materialverstärkung im Bereich des Hohlzapfens 25. Entsprechend dem Bolzen 10, 11 bei der Aussenschiene besitzt die Schubschiene im mittleren Bereich ebenfalls Bolzen 26,27 als Anschläge für die beiderseitige Auszugbegrenzung.Corresponding to the outer rail 1, the push rail 2 is also provided with longitudinal grooves 19, 20 and interrupted longitudinal grooves 21, 22 and 23, 24. The latter again receive an interruption for a material reinforcement in the area of the hollow pin 25. Corresponding to the pin 10, 11 in the outer rail, the push rail also has pins 26, 27 in the central area as stops for the pull-out limitation on both sides.

Wie aus den Fig. 4 bis 6 zu ersehen ist, besitzen sowohl die Aussenschiene 1 als auch die Schubschiene 2 in ihrem mittleren Bereich ihrer Innenflächen je eine Zahnstange 33 bzw. 34, die sich über die gesamte Länge von Aussen- und Schubschiene erstrecken. Die Zahnstangen 33, 34 bestehen einstückig aus gleichem Material wie die Schienen, sind also in das Material der Schienen eingearbeitet. Die gesamte Schubkasten-Auszugvorrichtung mit allen vorbeschriebenen und nachfolgend erläuterten Teilen besteht vorzugsweise aus einem zähharten Kunststoff, mit Ausnahme der Bolzen 9, 10 und 26, 27, die auch aus Metall hergestellt sein können.As can be seen from FIGS. 4 to 6, both the outer rail 1 and the push rail 2 each have a toothed rack 33 or 34 in their central region of their inner surfaces, which extend over the entire length of the outer and push rails. The racks 33, 34 are made in one piece from the same material as the rails, so they are incorporated into the material of the rails. The entire drawer pull-out device with all the parts described and explained below is preferably made of a tough, hard plastic, with the exception of the bolts 9, 10 and 26, 27, which can also be made of metal.

Die Schubkasten-Auszugvorrichtung besitzt zwischen Aussen- und Schubschiene die Mittelschiene 28. Die Mittelschiene 28 weist auf beiden nach der Aussen- und nach der Schubschiene liegenden Seiten die zwei längsverlaufende Nuten 29, 30 auf, die mit halbzylindrischen Anschlagflächen 31, 32 beiderseits kurz vor den Stirnflächen der Mittelschiene 28 enden, so dass beim Auszug in der einen oder anderen Richtung die Bolzen 9, 10 und 26, 27 an diese Anschlagflächen 31, 32 anschlagen und einen weiteren Auszug verhindern.The drawer pull-out device has the middle rail 28 between the outer and the push rail. The middle rail 28 has the two longitudinal grooves 29, 30 on both sides lying after the outer and after the push rail, which have semi-cylindrical stop surfaces 31, 32 on both sides just before the End faces of the central rail 28 end so that when pulling out in one direction or the other, the bolts 9, 10 and 26, 27 strike these stop faces 31, 32 and prevent further pulling out.

Die beiden Längsränder 40, 41 der Aussenschiene 1 sind gemäss Fig. 5 U-förmig geformt, derart, dass die freien Schenkel dieser U-förmigen Ränder mit Abstand und parallel zu den Schieneninnenflächen verlaufend nach innen gerichtet sind. Eine entsprechende Ausbildung besitzen auch die Längsränder 42 und 43 der Schubschiene. Die Mittelschiene 28 ist als massiver einstückiger Körper ausgebildet, dessen Längskanten leistenartige Vorsprünge 50 aufweisen, welche in die U-förmigen Ränder 40 bis 43 der Aussenschiene 1 und der Schubschiene 2 gleitfähig hineinragen.5, the two longitudinal edges 40, 41 of the outer rail 1 are U-shaped, such that the free legs of these U-shaped edges are directed inwards at a distance and parallel to the inner surfaces of the rails. The longitudinal edges 42 and 43 of the push rail also have a corresponding design. The middle rail 28 is designed as a solid, one-piece body, the longitudinal edges of which have strip-like projections 50 which protrude into the U-shaped edges 40 to 43 of the outer rail 1 and the push rail 2 in a slidable manner.

Die Mittelschiene 28 weist in der Mitte noch eine schmale im wesentlichen rechteckige Aussparung 36 auf, in welcher mittels einer Drehachse 35 ein Zahnrad 37 drehbar angeordnet ist, und zwar derart, dass es gleichzeitig in die beiden Zahnstangen 33 und 34 von Aussenschiene 1 und 1 nnenschiene 2 eingreift und dadurch eine Gleichlaufsteuerung in dem Sinne gewährleistet, dass beim Auszug oder beim Wiedereinschieben der Auszugvorrichtung die Mittelschiene gegenüber der Aussenschiene jeweils um die gleiche Strecke bewegt wird wie die Schubschiene gegenüber der Mittelschiene.The middle rail 28 also has a narrow, essentially rectangular recess 36 in the center, in which a gearwheel 37 is rotatably arranged by means of an axis of rotation 35, in such a way that it simultaneously into the two racks 33 and 34 of the outer rail 1 and inner rail 2 engages and thereby ensures a synchronization control in the sense that when pulling out or pushing the pull-out device again, the middle rail is moved relative to the outer rail by the same distance as the push rail relative to the middle rail.

Die Herstellung der oben erläuterten Schubkasten-Auszugvorrichtung ist verhältnismässig einfach, und zwar werden zunächst dieAussenschiene 1, die Schubschiene 2 und die Mittelschiene 28 und schliesslich das Zahnrad 37 mit Drehachse 35 einzeln hergestellt. Die Auszugvorrichtung besteht also nur aus sehr wenigen Einzelteilen. Sodann wird das Zahnrad 37 mit Drehachse 35 in die Aussparung 36 eingesetzt und Aussenschiene 1 und Schubschiene 2 von zwei einander gegenüberliegenden Enden bzw. Stirnseiten der Mittelschiene 28 aus auf diese aufgeschoben, so dass die Ränder 40 bis 43 in die Schlitzführungen 38, 39 der Mittelschiene eingreifen. Es brauchen dann nur noch beispielsweise in den Mittelstellungen gemäss den Fig. 1 und 3 die Bolzen 9, 10 und 26, 27 eingeschlagen oder eingepresst zu werden, um alle Teile der Schubkasten-Auszugvorrichtung unverlierbar zusammenzuhalten. Das Befestigen der Auszugvorrichtung zwischen Möbelstück und Schubkasten erfolgt in der Weise, dass zunächst die Aussenschiene 1 mit den Pratzen 11 bis 14 und den zugehörigen Zapfen 15 bis 18 in die vorbereiteten Bohrungen 46, 47 des Möbelstücks eingeschlagen werden, wobei noch eine grössere Haltesicherheit durch umlaufende kleine Ringwülste an den Zapfen erreicht werden kann. Sodann kann der Schubkasten 45 mit seiner Schubkastenrille 49 auf die Schubschiene aufgeschoben werden. Unter einem vorübergehenden leichten Spreizen der Auszugvorrichtung nach aussen kann der Schubkasten 45 so weit geschoben werden, bis der Hohlzapfen 25 einer vorbereiteten Bohrung 48 gegenübersteht. Durch Zurückführen der Auszugvorrichtung in die ordnungsgemässe Lage kommt der Hohlzapfen 25 mit der Bohrung 48 in festen Eingriff. Es wurde anhand der Zeichnung nur eine Schubkasten-Auszugvorrichtung beschrieben. Es versteht sich aber, dass zu jedem Schubkasten, und zwar an beiden einander gegenüberliegenden Längsseiten zwischen diesen und dem Möbelstück je eine Schubkasten-Auszugvorrichtung, also mindestens zwei Vorrichtungen vorgesehen sein müssen.The manufacture of the drawer pull-out device explained above is relatively simple, namely that the outer rail 1, the push rail 2 and the central rail 28 and finally the gearwheel 37 with axis of rotation 35 are manufactured individually. The pull-out device therefore consists of very few individual parts. Then the gearwheel 37 with the axis of rotation 35 is inserted into the recess 36 and the outer rail 1 and the push rail 2 are pushed onto the middle rail 28 from two opposite ends or end faces thereof, so that the edges 40 to 43 into the slot guides 38, 39 of the middle rail intervention. It is then only necessary, for example, to insert or press in the bolts 9, 10 and 26, 27 in the middle positions according to FIGS. 1 and 3 in order to hold all parts of the drawer pulling device together captively. The pull-out device is fastened between the piece of furniture and the drawer in such a way that first the outer rail 1 with the claws 11 to 14 and the associated pins 15 to 18 are hammered into the prepared bores 46, 47 of the piece of furniture, with even greater holding reliability due to circumferential small ring beads on the pins can be achieved. The drawer 45 with its drawer groove 49 can then be pushed onto the drawer rail. While temporarily pulling the pull-out device slightly outwards, the drawer 45 can be pushed until the hollow pin 25 faces a prepared bore 48. By returning the pull-out device to the correct position, the hollow pin 25 comes into firm engagement with the bore 48. Only one drawer puller has been described with reference to the drawing. However, it goes without saying that a drawer pull-out device, that is to say at least two devices, must be provided for each drawer, on both opposite longitudinal sides between these and the piece of furniture.
