Description

Die Erfindung betrifft eine doppelwandige Schubladenzarge mit einer Innenwand und einer Außenwand, die miteinander verbindbar, vorzugsweise verklebbar, sind, wobei die Innenwand einen Innenwandverbindungsabschnitt aufweist und die Außenwand einen Außenwandverbindungsabschnitt aufweist, wobei in Montageposition der Innenwandverbindungsabschnitt und der Außenwandverbindungsabschnitt im Inneren der doppelwandigen Schubladenzarge angeordnet sind und zur Verbindung der Innenwand mit der Außenwand miteinander verbindbar sind.The invention relates to a double-walled drawer frame having an inner wall and an outer wall, which are connectable, preferably glued, wherein the inner wall has an inner wall connecting portion and the outer wall has an outer wall connecting portion, wherein in mounting position of the inner wall connecting portion and the outer wall connecting portion are arranged inside the double-walled drawer and are connectable to each other for connection of the inner wall to the outer wall.

Doppelwandige Schubladenzargen werden häufig in einem automatisierten Produktionsprozess hergestellt. Dabei werden durch eine Fügevorrichtung die Innenwand und die Außenwand der doppelwandigen Schubladenzarge entsprechend in Position gebracht und mit einer geeigneten Verbindungstechnik miteinander verbunden, beispielsweise verschweißt, verklebt, vernietet, verschraubt oder geclincht. Insbesondere bei einer Verklebung der beiden Wände muss bislang die doppelwandige Schubladenzarge so lang in der Fügevorrichtung verweilen, bis der Kleber ausgehärtet ist und damit die Innenwand fest mit der Außenwand verbunden ist. Erst danach wird die Fügevorrichtung außer Eingriff mit Innenwand und Außenwand gebracht und die doppelwandige Schubladenzarge kann die weiteren Produktionsschritte durchlaufen.Double-walled drawer frames are often produced in an automated production process. In this case, the inner wall and the outer wall of the double-walled drawer frame are brought into position by a joining device and connected to one another with a suitable connection technology, for example, welded, glued, riveted, screwed or clinched. In particular, in a bonding of the two walls so far the double-walled drawer frame so long dwell in the joining device until the adhesive has cured and thus the inner wall is firmly connected to the outer wall. Only then, the joining device is brought out of engagement with the inner wall and outer wall and the double-walled drawer can go through the other production steps.

Eine andere Variante einer doppelwandigen Schubladenzarge ist in der US 5,478,146 A gezeigt. Bei der hierin gezeigten Schubladenzarge wird ein äußerer doppelwandiger Zargenteil über einen inneren doppelwandigen Zargenteil gestülpt.Another variant of a double-walled drawer is in the US 5,478,146 A shown. In the drawer frame shown herein, an outer double-walled frame portion is slipped over an inner double-walled frame portion.

Aufgabe der Erfindung ist es, eine gegenüber dem Stand der Technik verbesserte doppelwandige Schubladenzarge sowie ein verbessertes Verfahren zur Herstellung einer solchen anzugeben. Insbesondere soll der Produktionsprozess einer doppelwandigen Schubladenzarge verbessert bzw. beschleunigt werden.The object of the invention is to provide a comparison with the prior art improved double-walled drawer frame and an improved method for producing such. In particular, the production process of a double-walled drawer should be improved or accelerated.

Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Patentanspruchs 1 gelöst. Vorteilhafte Ausgestaltungen der Erfindung sind in den abhängigen Patentansprüchen angegeben.This object is achieved by the features of claim 1. Advantageous embodiments of the invention are specified in the dependent claims.

Gemäß der Erfindung ist also eine mit dem Innenwandverbindungsabschnitt und dem Außenwandverbindungsabschnitt verbindbare mechanische Haltevorrichtung vorgesehen, durch die die Innenwand relativ zur Außenwand lagestabil fixierbar ist.According to the invention, therefore, a mechanical holding device which can be connected to the inner wall connecting section and the outer wall connecting section is provided, by means of which the inner wall can be fixed in a positionally stable manner relative to the outer wall.

Indem die Innenwand durch eine mechanische Haltevorrichtung zumindest zeitweise relativ zur Außenwand lagestabil fixierbar ist, kann die Fügevorrichtung bereits frühzeitig außer Eingriff mit Innenwand und Außenwand gebracht werden, wodurch die weiteren Produktionsschritte bei der Herstellung einer doppelwandigen Schubladenzarge in einem automatisierten Produktionsprozess bereits früher als bisher durchgeführt werden können. Insbesondere bei einer Verklebung von Innenwand mit Außenwand kann somit die Verweilzeit der doppelwandigen Schubladenzarge an der Verklebestelle auf wenige Sekunden reduziert werden, obwohl die Aushärtezeit des Klebers möglicherweise mehrere Minuten beträgt. Dadurch kann die Taktzeit des Produktionsprozesses reduziert und somit die Menge an produzierten doppelwandigen Schubladenzargen pro Zeiteinheit gesteigert werden.By the inner wall by a mechanical holding device at least temporarily relative to the outer wall is fixed in position, the joining device can early be disengaged from the inner wall and outer wall, whereby the further production steps in the production of a double-walled drawer in an automated production process are carried out earlier than previously can. In particular, in a bonding of the inner wall to the outer wall thus the residence time of the double-walled drawer frame can be reduced to a few seconds at the Verklebestelle, although the curing time of the adhesive may be several minutes. Thereby, the cycle time of the production process can be reduced and thus the amount of produced double-walled drawer units per unit time can be increased.

Gemäß einer bevorzugten Ausführungsform kann vorgesehen sein, dass der Innenwandverbindungsabschnitt und der Außenwandverbindungsabschnitt in einem oberen Endbereich der doppelwandigen Schubladenzarge angeordnet sind, wobei vorzugsweise die Haltevorrichtung im Wesentlichen nur im Bereich von Innenwandverbindungsabschnitt und Außenwandverbindungsabschnitt angeordnet ist.

The double-walled drawer 1 comprises an inner wall 2 and an outer wall 3.

Die Innenwand 2 weist in diesem Beispiel einen Wandteil 22 auf, an den sich im oberen Endbereich des Wandteils 22 ein im Querschnitt im Wesentlichen U-förmiger Deckel 23 anschließt. Dieser Deckel 23 ist dabei durch einen entlang der oberen Längskante des Wandteils 22 umgebogenen Abschnitt gebildet und stellt gleichzeitig den oberen Rand der doppelwandigen Schubladenzarge 1 dar. An den Deckel 23 schließt ein Innenwandverbindungsabschnitt 2a an, der im Wesentlichen S-förmig ausgebildet ist und dadurch als Schwenklager für einen zu dieser Formgebung korrespondierenden Außenwandverbindungsabschnitt 3a der Außenwand 3 dient. An den S-förmigen Innenwandverbindungsabschnitt 2a schließt ein senkrechter Profilabschnitt als Endabschnitt 20 der Innenwand 2 an.The inner wall 2 has in this example a wall part 22, to which in the upper end region of the wall part 22 in a substantially U-shaped cross-section lid 23rd followed. This cover 23 is formed by a along the upper longitudinal edge of the wall portion 22 bent portion and at the same time represents the upper edge of the double-walled drawer 1 to the lid 23 includes an inner wall connecting portion 2a, which is formed substantially S-shaped and characterized as Swivel bearing for a corresponding to this shaping outer wall connecting portion 3a of the outer wall 3 is used. The S-shaped inner wall connecting portion 2a is adjoined by a vertical profile portion as the end portion 20 of the inner wall 2.

Die Außenwand 3 weist einen entlang der oberen Längskante hakenförmig gebogenen Außenwandverbindungsabschnitt 3a auf, der mit der Formgebung des Innenwandverbindungsabschnitts 2a korrespondiert und durch den die Außenwand 3 in den als Schwenklager ausgebildeten Innenwandverbindungsabschnitt 2a der Innenwand 2 einhängbar ist.The outer wall 3 has a hook-shaped outer wall connecting portion 3a along the upper longitudinal edge, which corresponds to the shape of the inner wall connecting portion 2a and through which the outer wall 3 can be suspended in the inner wall connecting portion 2a of the inner wall 2 formed as a pivot bearing.

Zur Verbindung der Innenwand 2 mit der Außenwand 3 ist in diesem Beispiel am Endabschnitt 20 der Innenwand 2 ein in Richtung der Längserstreckung der Innenwand 2 verlaufender Klebestreifen 21 angeordnet (siehe Fig. 3). Der dabei zum Einsatz kommende Kleber kann z.B. ein Zweikomponentenkleber sein, der vor dem Einhängen der Außenwand 3 in den Innenwandverbindungsabschnitts 2a durch einen automatisierten Prozess auf den Endabschnitt 20 der Innenwand 2 aufgetragen wird. Zur Verbindung der Innenwand 2 mit der Außenwand 3 in einem unteren Endbereich der doppelwandigen Schubladenzarge 1 ist darüber hinaus auch auf einem Innenwandendabschnitt 24 ein weiterer Klebestreifen 21 angeordnet, der ebenfalls durch einen automatisierten Prozess aufgetragen werden kann (siehe Fig. 3).To connect the inner wall 2 with the outer wall 3, an adhesive strip 21 extending in the direction of the longitudinal extension of the inner wall 2 is arranged in this example at the end section 20 of the inner wall 2 (see FIG Fig. 3 ). The adhesive used in this case can be, for example, a two-component adhesive, which is applied to the end section 20 of the inner wall 2 by an automated process before the outer wall 3 is hooked into the inner wall connecting section 2a. For connecting the inner wall 2 to the outer wall 3 in a lower end region of the double-walled drawer 1, a further adhesive strip 21 is also arranged on an inner wall end section 24, which can also be applied by an automated process (see Fig. 3 ).

Der Innenwandendabschnitt 24 ist in diesem Beispiel mit einer an sich bekannten Behältnisschiene 17 verbunden (z.B. verschweißt, vernietet, geclincht), welche in weiterer Folge in bekannter Art und Weise mit einem Schubladenboden 16 zu verbinden ist.The inner wall end portion 24 is in this example connected to a per se known container rail 17 (e.g., welded, riveted, clinched), which is subsequently to be connected to a drawer bottom 16 in a known manner.

Nach dem Einhängen der Außenwand 3 mit ihrem hakenförmigen Außenwandverbindungsabschnitt 3a in den im Wesentlichen S-förmig ausgebildeten Innenwandverbindungsabschnitt 2a kann die Außenwand 3 in Richtung der Innenwand 2 verschwenkt werden bis die Außenwand 3 im Wesentlichen parallel zur Innenwand 2 angeordnet ist und an die Klebestreifen 21 angepresst wird. Um die Außenwand 3 besser mit dem Klebestreifen 21 am Innenwandendabschnitt 24 verpressen zu können, weist der Außenwandendabschnitt 25 eine nasenförmige Ausbuchtung 26 auf, die in den Klebestreifen 21 eingedrückt wird und damit eine bessere Haftwirkung erzielt.After attaching the outer wall 3 with its hook-shaped outer wall connecting portion 3a in the substantially S-shaped inner wall connecting portion 2a, the outer wall 3 in the direction of the inner wall 2 are pivoted until the outer wall 3 is arranged substantially parallel to the inner wall 2 and is pressed against the adhesive strip 21. In order to be able to press the outer wall 3 better with the adhesive strip 21 on the inner wall end section 24, the outer wall end section 25 has a nose-shaped recess 26, which is pressed into the adhesive strip 21 and thus achieves a better adhesive effect.

Um während des Aushärtens des Klebers der Klebestreifen 21 die Innenwand 2 relativ zur Außenwand 3 lagestabil zu fixieren, ist eine mechanische Haltevorrichtung 4 vorgesehen, die - über die Stirnseite 13 der doppelwandigen Schubladenzarge 1 eingeführt - in Form einer Halteklammer mit Innenwandverbindungsabschnitt 2a und Außenwandverbindungsabschnitt 3a verbunden werden kann und dadurch die Klebestelle zumindest so lange fixiert, bis der Kleber vollständig ausgehärtet ist.In order to fix the inner wall 2 relative to the outer wall 3 during the curing of the adhesive of the adhesive strips 21, a mechanical holding device 4 is provided, which - introduced over the end face 13 of the double-walled drawer 1 - connected in the form of a retaining clip with inner wall connecting portion 2a and outer wall connecting portion 3a can be and thus fixed the splice at least until the adhesive is completely cured.

Fig. 3 zeigt eine perspektivische Darstellung der doppelwandigen Schubladenzarge 1 gemäß Fig. 2a, wobei aus Gründen der Übersichtlichkeit die Außenwand 3 entfernt wurde. In dieser Ausführungsvariante verläuft die Verbindung des Innenwandendabschnitts 24 mit der Behältnisschiene 17 nicht entlang der gesamten Längserstreckung der Behältnisschiene 17, sondern die Innenwand 2 weist im vorderen und hinteren Endbereich der Behältnisschiene 17 entsprechende Aussparungen auf. Dadurch können in diesen Bereichen ein Frontaufsatz 18 und ein Rückaufsatz 19 direkt mit der Behältnisschiene 17 verbunden werden, beispielsweise durch Schweißen oder Nieten. Am Rückaufsatz 19 kann in weiterer Folge ein Rückwandhalter 27 angebracht werden, der zur Befestigung einer Rückwand 15 einer Schublade 12 dient und am Frontaufsatz 18 kann eine hier nicht gezeigte Frontbeschlagsbaugruppe angebracht werden, die in weiterer Folge zur Befestigung und/oder Höhen- und Seitenverstellung einer Frontblende 14 einer Schublade 12 dient (siehe Fig. 1). In ihren oberen Endbereichen sind Frontaufsatz 18 und Rückaufsatz 19 jeweils mit dem im Wesentlichen vertikal abstehenden Endabschnitt 20 der Innenwand 2 verbunden, beispielsweise verschweißt. Am vertikalen Endabschnitt 20 der Innenwand 2, der sich an den Innenwandverbindungsabschnitt 2a anschließt, ist in diesem Beispiel zwischen Frontaufsatz 18 und Rückaufsatz 19 zum Verkleben der Außenwand 3 mit der Innenwand 2 ein Klebestreifen 21 angeordnet. Auch am unteren mit der Behältnisschiene 17 verbundenen Innenwandendabschnitt 24 der Innenwand 2 ist zum Verkleben der Außenwand 3 mit der Innenwand 2 ein Klebestreifen 21 angebracht. Fig. 3 shows a perspective view of the double-walled drawer 1 according to Fig. 2a , wherein for reasons of clarity, the outer wall 3 has been removed. In this embodiment, the connection of the inner wall end portion 24 with the container rail 17 does not extend along the entire longitudinal extent of the container rail 17, but the inner wall 2 has corresponding recesses in the front and rear end region of the container rail 17. As a result, in these areas, a front attachment 18 and a rear attachment 19 can be connected directly to the container rail 17, for example by welding or riveting. The rear attachment 19 can subsequently be attached to a rear wall holder 27 which serves for fastening a rear wall 15 of a drawer 12 and the front attachment 18, a front fitting assembly not shown here are attached, which subsequently for attachment and / or height and lateral adjustment of a Front panel 14 of a drawer 12 is used (see Fig. 1 ). In their upper end areas front attachment 18 and rear attachment 19 are each connected to the substantially vertically projecting end portion 20 of the inner wall 2, for example, welded. At the vertical end portion 20 of the inner wall 2, which adjoins the inner wall connecting portion 2a, an adhesive strip 21 is arranged in this example between the front attachment 18 and the rear attachment 19 for bonding the outer wall 3 to the inner wall 2. Also at the bottom connected to the container rail 17 Innenwandendabschnitt 24 of the inner wall 2, an adhesive strip 21 is attached to the bonding of the outer wall 3 with the inner wall 2.
