Description

Die Erfindung betrifft eine Einzugsvorrichtung für Schubladen gemäß dem Oberbegriff des Patentanspruches 1.The invention relates to a draw-in device for drawers according to the preamble of patent claim 1.

Eine derartige Einzugsvorrichtung ist dem Prinzip nach aus der WO 92/04843 A bekannt. Sie soll gewährleisten, daß die Schublade ab einer bestimmten Einschiebestellung selbsttätig in die Schließlage gezogen und in dieser Schließlage durch die Federn festgehalten wird. Die Federn werden beim Ausziehen der Schublade vorgespannt.Such a drawing-in device is known in principle from WO 92/04843 A. It is intended to ensure that the drawer is automatically pulled into the closed position from a certain insertion position and held in this closed position by the springs. The springs are pretensioned when the drawer is pulled out.

Bei dieser bekannten Einzugsvorrichtung gehen die Linearführungen gegen das Auszugsende hin in eine Verbreiterung über, die eine Kulissenführung für das als Gleitstein ausgebildete Verbindungselement, an dem die Feder seitlichmittig angreift, darstellen. Für das abgerundete Vorderende des Mitnehmers weist diese Kulissenführung zunächst abgeschrägt nach außen, geht dann in einen parallel zur Linearführung verlaufenden geraden Teil über und schließt mit einer Anschlagwand ab. Für das abgeschrägte Hinterende des Verbindungselementes geht seine Linearführung in einen nach außen gerichteten Bogen und dann in einen wieder linearen Führungsteil über. Eine Ecke zwischen Bogen und linearem Führungsteil der Kulissenführung soll einen Rastanschlag für dieses abgeschrägte Ende des Verbindungselementes bilden. Beim Ausziehen kippt das Verbindungselement in eine Schräglage zwischen den beiden Linearteilen der Kulissenführung und liegt mit seiner hinteren Schrägseite am erwähnten Bogen an.In this known retraction device, the linear guides move towards the extension end into a widening, which is a link guide for the connecting element designed as a sliding block, on which the spring engages laterally in the center. For the rounded front end of the driver, this link guide is initially beveled to the outside, then merges into a straight part running parallel to the linear guide and ends with a stop wall. For the bevelled rear end of the connecting element, its linear guide merges into an outwardly directed arc and then into a linear guide part again. A corner between the arc and the linear guide part of the link guide is intended to form a detent stop for this bevelled end of the connecting element. When pulling out, the connecting element tilts into an inclined position between the two linear parts of the link guide and lies with its rear oblique side on the arch mentioned.

Nachteilig bei der bekannten Konstruktion sind das aufwendige, wegen der Kulissenführung breite Führungsgehäuse, was den Einbau erschwert und eine nicht eindeutig definierte Gesamtfunktion, wobei sowohl die Möglichkeit gegeben ist, daß am Ende des Auszugsweges keine ordnungsgemäße Verrastung stattfindet und dadurch das Verbindungselement nach Freigabe der Lade durch die Feder in die Ausgangslage zurückgezogen wird, also die Einzugsvorrichtung ihre Funktion verliert, als auch nach der anderen Möglichkeit über den auflaufenden Mitnehmer beim Schlieen der Lade ein beträchtlicher Durck zum Lösen der Verrastung ausgeübt werden muß, so daß schließlich das Verbindungselement unter starker Geräuschentwicklung aus der Verrastung gelöst wird. Wegen der möglichen Fehlfunktion ist im Halteteil eine Fangvorrichtung vorgesehen, mit deren Hilfe das Verbindungselement dann, wenn keine ordnungsgemäße Verrastung mit dem Mitnehmer stattgefunden hat, neuerlich in der voll eingezogenen Stellung mit dem Mitnehmer gekuppelt und ausgezogen werden kann.Disadvantages of the known construction are the complex, wide guide housing because of the link guide, which complicates the installation and an overall function which is not clearly defined, both giving the possibility that no proper locking takes place at the end of the extension path and thereby the connecting element after releasing the drawer is retracted by the spring into the starting position, that is to say the pulling device loses its function, and, according to the other possibility, a considerable pressure must be exerted to release the latching when the drawer is closed when the drawer is closed, so that finally the connecting element emits a lot of noise the latch is released. Because of the possible malfunction, a catch device is provided in the holding part, with the aid of which the connecting element can be coupled and pulled out again in the fully retracted position when the catch has not been properly latched to the catch.

Eine aus der EP-B 0 386 731 bekannte Einzugsvorrichtung sieht innerhalb des Gehäuses eine Kulissenführung für das Verbindungselement vor, die am einzugsseitigen Ende einen Anschlag für einen Führungsbolzen des Verbindungselementes aufweist und am anderen Ende eine Krümmung besitzt, die das Verbindungselement am Ende des Auszugsweges in die den Mitnehmer freigebende Kipplage leitet. Die Konstruktion ist zwar betriebssicher, im Gesamtaufbau aber sehr aufwendig und hat ein relativ großes Bauvolumen, wodurch die Unterbringung an den Korpusschienen erschwert wird. Nachteilig ist auch, daß bei dieser Einzugsvorrichtung eine Montage mit hochgestelltem Führungsgehäuse notwendig ist, wodurch sich die Lage des Mitnehmers zur Rast je nach Belastung der Lade verändern kann und sogar die Gefahr besteht, daß der Mitnehmer beim Einfahren der Lade die Verrastung verfehlt. Bei Weiterbildungen dieser Konstruktion hat man danach getrachtet, das Bauvolumen zu verinngern und die Anordnung so zu treffen, daß auch eine liegende Montage des Gehäuses möglich wird, wobei zur Vereinfachung des Gesamtaufbaues ein rinnenförmiges Gehäuse vorgesehen wird, das mit zur Korpusschiene weisender Profilöffnung montiert wird. Bei einer Ausführung der Einzugsvorrichtung nach der EP-A 391 221 wird das Verbindungselement über zwei Zapfen in einer von einer Nut oder Rille gebildeten Führungsbahn des Führungsgehäuses geführt, wobei auch hier die Führungsbahn am ausziehseitigen Ende in einen Bogen übergeht, um den Halteteil in die Ausziehkipplage zu leiten.A pull-in device known from EP-B 0 386 731 provides a link guide for the connecting element within the housing, which has a stop for a guide pin of the connecting element at the pull-in end and has a curvature at the other end which the connecting element has at the end of the pull-out path that guides the tipping position that releases the driver. The construction is reliable, but the overall structure is very complex and has a relatively large volume, which makes it difficult to accommodate on the carcass rails. Another disadvantage is that with this retraction device an assembly with a raised guide housing is necessary, whereby the position of the driver to rest depending on the load on the The drawer can change and there is even the risk that the driver misses the catch when the drawer is retracted. In further developments of this construction, it has been sought to reduce the construction volume and to arrange the arrangement in such a way that a horizontal installation of the housing is also possible, a channel-shaped housing being provided to simplify the overall construction, which is mounted with a profile opening facing the body rail. In an embodiment of the pull-in device according to EP-A 391 221, the connecting element is guided via two pins in a guide track of the guide housing formed by a groove or groove, the guide track also merging into an arch at the end on the pull-out side, around the holding part in the pull-out tilt position to lead.

Nach der DE-A 41 24 512 wird angestrebt, mit einer einfachen Linearführung des Führungsgehäuses das Auslangen zu finden. Um dies zu erreichen, wird allerdings im rinnenförmigen Führungsgehäuse lediglich ein mit der Feder verbundener Schlitten gelagert und an diesem Schlitten erst ein Kippsegment angebracht, das die Aufnahmerast für den Mitnehmer besitzt und sich mit einem Fühler an einem eigenen Führungssteg abstützt, der es am Ende des Auszugsweges so weit freigibt, daß der Mitnehmer aus der Rast austreten kann. Auch hier ergibt die mehrteilige Ausbildung einen aufwendigen Aufbau. Die schwenkbare Lagerung des Kippsegmentes am Schlitten ist nicht betriebssicher und das Gesamtbauvolumen ist so groß, daß fallweise der Einbau erschwert wird.According to DE-A 41 24 512, the aim is to find sufficiency with a simple linear guide of the guide housing. To achieve this, however, only a slide connected to the spring is stored in the trough-shaped guide housing and only a tilting segment is attached to this slide, which has the locating catch for the driver and is supported by a sensor on its own guide bar, which supports it at the end of the The extension path releases so far that the driver can emerge from the rest. Here, too, the multi-part training results in a complex structure. The pivotable mounting of the tilting segment on the slide is not reliable and the total construction volume is so large that installation is sometimes difficult.

Aufgabe der Erfindung ist demnach die Schaffung einer Einzugsvorrichtung der eingangs genannten Art, die bei einfachstem Aufbau leicht montierbar ist, ein geringes Bauvolumen aufweist und bei der trotzdem eine hohe Betriebs- sicherheit und ein geräuscharmer Betrieb gewährleistet bleibt.The object of the invention is accordingly to create a feed device of the type mentioned at the outset, which is easy to assemble with the simplest construction, has a small overall volume and nevertheless ensures high operational reliability and low-noise operation.

Die gestellte Aufgabe wird durch die Merkmalskombination des Patentanspruches 1 gelöst.The object is achieved by the combination of features of claim 1.

Das Führungsgehäuse besitzt nur einfache Linearführungen und das Verbindungselement kann trotzdem einfach und einteilig ausgebildet werden. Es ergibt sich eine geringe Gesamtbauhöhe und die Teile können problemlos zusammengesetzt und montiert werden, wobei man wieder eine Montage mit zur Korpusschiene weisender Rinnenöffnung vorsehen wird, so daß die wesentlichen Teile der Einzugsvorrichtung und insbesondere die Führungen vor Verschmutzung geschützt bleiben. Entscheidend für die Erfindung ist die Erkenntnis, daß man durch die entsprechende Konstruktion des Rastvorsprunges und die Anordnung der Rastvertiefung bzw. Rast-Öffnung auf die bisherigen aufwendigen Kulissenführungen verzichten kann, obwohl das Verbindungselement einteilig hergestellt ist und sowohl als Mitnehmer für die Feder als auch als Verrastungseinrichtung in beiden Kipplagen dient. Neben der hohen Betriebssicherheit ist auch ein sehr geräuscharmer Betrieb gewährleistet.The guide housing has only simple linear guides and the connecting element can nevertheless be constructed simply and in one piece. There is a low overall height and the parts can be assembled and assembled without any problems, whereby again an assembly with a channel opening facing the cabinet rail will be provided, so that the essential parts of the feed device and in particular the guides remain protected from contamination. Crucial for the invention is the knowledge that one can do without the previous elaborate backdrop guides by the corresponding construction of the locking projection and the arrangement of the locking recess or locking opening, although the connecting element is made in one piece and both as a driver for the spring and as Latching device serves in both tilt positions. In addition to high operational reliability, very low-noise operation is also guaranteed.

Durch eine Ausgestaltung gemäß Anspruch 2 wird jede der beiden Kippstellungen eindeutig definiert und eine ordnungsgemäße Funktion gewährleistet. Der in die Aufnahmerast eingreifende Zapfen erzeugt selbst beim Ausziehen der Lade ein auf den Mitnehmer wirkendes Kippmoment, so daß er den Mitnehmer beim Erreichen der Rastöffnung oder -vertiefung entsprechend in die Freigabelage kippt.By an embodiment according to claim 2, each of the two tilt positions is clearly defined and a proper function is guaranteed. The pin engaging in the receiving peg generates a tilting moment acting on the driver even when the drawer is pulled out, so that it accordingly tilts the driver into the release position when it reaches the latching opening or recess.

Um einen im Verhältnis zu dem vom Mitnehmer auf die Rast erzeugten Hub größeren Verstellweg des Rastvorsprunges zu erzielen, kann eine Ausführung nach Anspruch 3 gewählt werden, bei der das Verbindungselement praktisch am kürzeren Schenkelteil eines einarmigen Hebels angreift, der um die Kippachse schwenkbar ist und am längeren Schenkel den Rastvorsprung bildet.In order to achieve a larger adjustment path of the locking projection in relation to the stroke generated by the driver on the catch, an embodiment can be selected according to claim 3, in which the connecting element engages practically on the shorter leg part of a one-armed lever, which is pivotable about the tilt axis and on longer leg the locking projection forms.

Die Einzugsvorrichtung besitzt ein Führungsgehäuse 1, das einen rinnenförmigen, beim Ausführungsförmig ungleichschenkelig U-förmigen Querschnitt aufweist, an den Enden durch Querwände 2, 3 abgeschlossen ist und mit zu einer nur in den Fig. 2 und 4 angedeuteten Korpusschiene 4 weisender Gehäuseöffnung an dieser Korpusschiene, wie dargestellt, stehend oder auch unterseitig an einer solchen Korpusschiene anliegend, also liegend, in Längsrichtung der Korpusschiene befestigt werden kann. Das Gehäuse 1 reicht nur über einen Teil der Länge der Korpusschiene. Der breitere obere Flansch 5 und der schmälere untere Flansch 6 des Gehäuses 1 bilden mit ihrer Innenseite Linearführungen für ein Verbindungselement 7, das seinerseits für die wechselweise Anlage an diesen Linearführungen bestimmte Führungsflächen 8 und 9 aufweist und mit einem neben dem verkürzten Flansch 6 aus dem Gehäuse 1 herausragenden Halteteil 10 versehen ist. In diesem Halteteil ist eine Verrastungsvertiefung 11 vorgesehen, die ausziehseitig von einer kürzeren Nase 12 und einschubseitig von einer längeren Nase 13 begrenzt ist. In der Stellung nach den Fig. 1 und 2 greift ein Zapfen 14 der nicht dargestellten Lade in die Verrastungsvertiefung 11 ein. Innerhalb des Gehäuses 1 ist eine mit dem Verbindungselement 7 verbundene Zugfeder 15 angebracht, die beim Ausziehen der Lade über Zapfen 14 und Verbindungselemet 7 vorgespannt wird.The retraction device has a guide housing 1, which has a channel-shaped cross section, which in the embodiment has an unequal leg U-shaped cross section, is closed at the ends by transverse walls 2, 3 and has a housing opening on this body rail, which only points to the body rail 4 indicated in FIGS. 2 and 4 , as shown, standing or also on the underside of such a body rail, that is to say lying, can be fastened in the longitudinal direction of the body rail. The housing 1 only extends over part of the length of the body rail. The wider upper flange 5 and the narrower lower flange 6 of the housing 1 form with their inside linear guides for a connecting element 7, which in turn has certain guide surfaces 8 and 9 for the alternating contact with these linear guides and with a shortened flange 6 from the housing 1 outstanding holding part 10 is provided. In this holding part a locking recess 11 is provided, the pull-out side of a shorter nose 12 and insertion side is limited by a longer nose 13. In the position according to FIGS. 1 and 2, a pin 14 of the drawer, not shown, engages in the locking recess 11. A tension spring 15 connected to the connecting element 7 is mounted inside the housing 1 and is biased via the pin 14 and the connecting element 7 when the drawer is pulled out.

Mit Längsabstand von der Verrastungsvertiefung 11 trägt das Verbindungselement 7 einen hakenförmigen Rastvorsprung 16, der in der Stellung nach Fig. 1 mit seinem Ende an der Innenseite des Flansches 5 anliegt und gemeinsam mit der Führungsfläche 8 und einer von der Fläche 9 ausgehenden Rundung das Verbindungselement 7 an den Flanschen 5, 6 führt.At a longitudinal distance from the locking recess 11, the connecting element 7 carries a hook-shaped locking projection 16, which in the position according to FIG. 1 rests with its end on the inside of the flange 5 and, together with the guide surface 8 and a curve starting from the surface 9, the connecting element 7 leads on the flanges 5, 6.

Das Ende des möglichen Auszugsweges ist durch eine Verrastungsöffnung 17 im Flansch 5 bestimmt, in die der Verrastungshaken 16, wie in Fig. 3 dargestellt, eintreten kann. Dabei ist festzuhalten, daß der Zapfen 14 durch seine Anlage an der Nase 12 während des Ausziehvorganges ein Kippmoment auf den Halteteil 17 ausübt, das den Haken 16 zunächst gegen die Innenseite des Flansches 5 drückt und beim Erreichen der Rastöffnung 17 das Ausschwenken des Hakens 16 unter Kippung des gesamten Verbindungselementes 7 bewirkt. In der Stellung nach Fig. 3 gibt die Nase 12 und damit die Rastöffnung 11 den Zapfen 14 frei, so daß die Lade nun frei ausgezogen werden kann. Der hakenförmige Rastvorsprung 16 verrastet mit dem Rand der Öffnung 17 und hält dadurch das Verbindungselement 7 und die vorgespannte Feder 15 in der Lage nach Fig. 3.The end of the possible extension path is determined by a latching opening 17 in the flange 5, into which the latching hook 16 can enter, as shown in FIG. 3. It should be noted that the pin 14 by its abutment on the nose 12 exerts a tilting moment on the holding part 17 during the pull-out process, which first presses the hook 16 against the inside of the flange 5 and when the latch opening 17 reaches the pivoting out of the hook 16 under Tilting of the entire connecting element 7 causes. In the position according to FIG. 3, the nose 12 and thus the latching opening 11 releases the pin 14, so that the drawer can now be pulled out freely. The hook-shaped latching projection 16 latches with the edge of the opening 17 and thereby holds the connecting element 7 and the prestressed spring 15 in the position according to FIG. 3.

Beim Einfahren der Lade trifft der Zapfen 14 auf die Nase 13 auf und erzeugt dadurch ein Rückkippmoment, wodurch sich der Haken 16 aus seiner Verrastung mit dem Rand der Öffnung 17 löst und wieder unter den Flansch 5 eintritt, so daß die Relativlage der Rastöffnung 11 und des Zapfens 14 erreicht wird, wie sie in Fig. 1 dargestellt wurde. Die Feder 15 hat nun das Bestreben, die Lade in die Schließstellung zu ziehen und bewirkt den entsprechenden Einzug nach Freigabe der Lade.When the drawer is retracted, the pin 14 strikes the nose 13 and thereby generates a tilting moment, as a result of which the hook 16 disengages from the edge of the opening 17 releases and enters again under the flange 5, so that the relative position of the locking opening 11 and the pin 14 is reached, as was shown in Fig. 1.
