Description

Stand der Technik:State of the art:

Schubladen bzw. Auszüge von Möbeln werden in der Regel aus Einzelelementen zusammengebaut. Hierfür kommen unterschiedlichste Verbindungsarten zum Einsatz.Drawers or extracts of furniture are usually assembled from individual elements. For this purpose, a wide variety of connection types are used.

Bei Holzschubladen beispielsweise können die Wandelemente untereinander durch einfache Klebe- bzw. Zapfenverbindungen verbunden sein.In wood drawers, for example, the wall elements can be interconnected by simple adhesive or pin connections.

Wandelemente von Schubladen können auch über andere insbesondere wieder lösbare Verbindungsanordnungen miteinander verbunden werden zum Beispiel durch Verrasten.Wall elements of drawers can also be connected to each other via other particular releasable connection arrangements, for example by locking.

Die GB 2 224 673 A betrifft eine Schubladenanordnung mit einem Eckverbinder in einem Eckbereich zwischen einer Rückwand und Seitenteilen einer Schublade. Die Eckverbinder verbinden jeweils eine Schmalseite der Seitenelemente und der Rückwand und bilden einen sichtbaren Eckbereich der Schublade.The GB 2 224 673 A relates to a drawer assembly having a corner connector in a corner region between a rear wall and side parts of a drawer. The corner connectors each connect a narrow side of the side elements and the rear wall and form a visible corner of the drawer.

Die CH 695 182 A5 thematisiert eine Vorrichtung zur Befestigung einer Frontwand an einer Schublade.The CH 695 182 A5 discusses a device for attaching a front wall to a drawer.

Aufgabe und Vorteile der Erfindung:Object and advantages of the invention:

Aufgabe der vorliegenden Erfindung ist es, eine technisch intelligente und wirtschaftlich vorteilhafte Verbindungsart für Schubladenelemente bereitzustellen.The object of the present invention is to provide a technically intelligent and economically advantageous type of connection for drawer elements.

Diese Aufgabe wird durch die unabhängigen Ansprüche gelöst.This object is solved by the independent claims.

In den abhängigen Ansprüchen sind vorteilhafte Varianten der Erfindung aufgezeigt.In the dependent claims advantageous variants of the invention are shown.

Die Erfindung geht aus, von einer Vorrichtung zum Verbinden von Wandelementen einer Schublade, wobei eine Rastverbindung ausbildbar ist und die Wandelemente im verbundenen Zustand zumindest einen Teil einer Schubladenwand der Schublade bilden und wobei die Schubladenwand eine Frontwand, eine Rückwand und/oder wenigstens eine Seitenwand umfasst. Ein Schubladenboden bildet als weiteres verbundenes Schubladenelement einen unteren Abschluss der Schublade. Die Rastverbindung ist insbesondere ohne Werkzeuge einrichtbar bzw. auch wieder lösbar.The invention relates to a device for connecting wall elements of a drawer, wherein a latching connection can be formed and the wall elements in the connected state form at least part of a drawer wall of the drawer and wherein the drawer wall is a front wall, a rear wall and / or at least one side wall. A drawer bottom forms as another connected drawer element a lower end of the drawer. The latching connection can be set up or released again in particular without tools.

Der Kern der Erfindung liegt darin, dass ein Verbindungselement mit verbiegbaren Rastabschnitten für die Ausbildung der Rastverbindung vorgesehen ist, wobei das Verbindungselement als separates Bauteil derart ausgebildet ist, dass das Verbindungselement an einer Stirnseite und an einer Flächenseite eines der zu verbindenden Wandelemente verankerbar ist und das Verbindungselement ausgebildet ist, die Rastverbindung der Wandelemente in einem Bereich einzurichten, in dem die Stirnseite des Wandelements an der Flächenseite des anderen Wandelements stumpf anstößt, wobei die verbiegbaren Rastabschnitte ein selbsttätiges Einrichten der Rastverbindung an entsprechenden Gegenabschnitten der Wandelemente ermöglichen. Damit kann das Verbindungselement für die Verbindung von zwei Wandelementen an einem der zu verbindenden Wandelemente z. B. an der Stirnseite verankert werden, und dort positionsfest verbleiben. Anschließend kann für die Fertigstellung der Verbindung der Wandelemente das Verbindungselement an der Flächenseite des anderen Wandelements ebenfalls verankert werden. Das Verbindungselement ist so ausgestaltet bzw. auf die Wandelemente abgestimmt, dass auch genau umgekehrt vorgegangen werden kann, also das Verbindungselement zunächst an einer Flächenseite des einen Wandelements fixiert wird und anschließend an der Stirnseite des anderen Wandelements verankert wird. Das Verbindungselement und die Wandelemente sind insbesondere so aufeinander abgestimmt, dass die Verankerung an beiden Wandelementen jeweils durch eine lösbare Rastverbindung realisiert ist. Die konkrete Ausbildung der Rastverbindung mit einem Verbindungselement kann für beide zu verbindenden Wandelemente gleichartig oder unterschiedlich sein. Bevorzugt ist ein Verbindungselement derart gestaltet, dass es mit einem Wandelement eine Art von Rastverbindung ausbilden kann, die sich von der Art der Rastverbindung, die das Verbindungselement mit dem anderen Wandelement ausbilden kann, unterscheidet. Es ist allerdings vorteilhaft, dass es wahlweise möglich ist, zuerst die Rastverbindung mit der Stirnseite des einen Wandelements und dann mit der Flächenseite des anderen Wandelements einzurichten oder umgekehrt.The essence of the invention is that a connecting element is provided with bendable locking portions for the formation of the locking connection, wherein the connecting element is designed as a separate component such that the connecting element is anchored to a front side and on a surface side of one of the wall elements to be connected and the Connecting element is designed to establish the latching connection of the wall elements in a region in which abuts the end face of the wall element on the surface side of the other wall element blunt, wherein the bendable latching sections allow an automatic setting of the latching connection at corresponding opposite portions of the wall elements. Thus, the connecting element for the connection of two wall elements to one of the wall elements to be connected z. B. anchored to the front, and there remain fixed in position. Subsequently, for the completion of the connection of the wall elements, the connecting element can also be anchored to the surface side of the other wall element. The connecting element is designed or matched to the wall elements, that the procedure can be reversed exactly, ie the connecting element is first fixed to a surface side of the one wall element and then anchored to the end face of the other wall element. The connecting element and the wall elements are particularly coordinated so that the anchoring is realized on both wall elements in each case by a releasable latching connection. The specific design of the latching connection with a connecting element can be the same or different for both wall elements to be connected. Preferably, a connecting element is designed such that it can form a kind of latching connection with a wall element, which differs from the type of latching connection which can form the connection element with the other wall element. However, it is advantageous that it is optionally possible to first establish the latching connection with the end face of the one wall element and then with the surface side of the other wall element or vice versa.

Eine Stirnseite eines Wandelements ist eine Schmalseite bei einem z. B. plattenartigen Wandelement, die sich über eine Wanddicke erstreckt und eine Außenfläche bildet, deren Längserstreckung im Nutzzustand der Schublade vertikal verläuft. Eine Stirnseite des Wandelements ergibt sich zum Beispiel durch einen Schnitt durch ein plattenartiges Vorprodukt des Wandelements, wobei der Schnitt in Richtung einer Materialdicke des Wandelements verläuft. Zwischen zwei gegenüberliegenden Stirnseiten erstrecken sich weitere zwei gegenüberliegende Längsschmalseiten. Eine erste Flächenseite eines Wandelements bildet die überwiegende Außenfläche des Wandelements und ist von einer gegenüberliegenden zweiten Flächenseite, die eine weitere Außenfläche bildet, durch die Dicke des Wandelements bzw. die vier Schmalseiten getrennt. Ein quaderförmiges Wandelement mit rechteckigen Flächenseiten weist demnach zwei gegenüberliegende Flächenseiten auf, zwei gegenüberliegende Längsschmalseiten und zwei gegenüberliegende Stirnseiten.An end face of a wall element is a narrow side at a z. B. plate-like wall element which extends over a wall thickness and forms an outer surface whose longitudinal extent in the use state of the drawer is vertical. An end face of the wall element is obtained, for example, by a section through a plate-like precursor of the wall element, the section extending in the direction of a material thickness of the wall element. Between two opposite end faces further two opposite longitudinal narrow sides extend. A first surface side of a wall element forms the predominant outer surface of the wall element and is separated from an opposite second surface side, which forms a further outer surface, by the thickness of the wall element or the four narrow sides. A cuboid wall element with rectangular surface sides accordingly has two opposite surface sides, two opposite longitudinal narrow sides and two opposite end sides.

Mit dem Verbindungselement kann flexibel und in wenigen Arbeitsschritten der Zusammenbau von Wandelementen einer Schublade erfolgen. Insbesondere werkzeuglos bzw. von Hand. Insbesondere können mit einer einzigen Ausgestaltung des Verbindungselements sozusagen universell alle Verbindungen, die für den Zusammenbau der Schublade aus den Wandelementen nötig sind, realisiert werden. Entsprechendes gilt für die an den Wandelementen ausgebildeten Eingreifabschnitte, die nötig sind, damit das Verbindungselement an den Wandelementen positionsrichtig verrastbar ist. Dieses einheitliche bzw. reduzierte Verbindungssystem erleichtert den Zusammenbau und minimiert die Kosten für die Schublade bzw. deren Montage.With the connecting element can be done flexibly and in a few steps, the assembly of wall elements of a drawer. Especially without tools or by hand. In particular, all connections which are necessary for the assembly of the drawer out of the wall elements can, as it were, be realized with a single embodiment of the connecting element. The same applies to the formed on the wall elements engaging portions, which are necessary so that the connecting element can be latched positionally correct position on the wall elements. This uniform or reduced connection system facilitates assembly and minimizes the cost of the drawer or its assembly.

Mit den insbesondere federartig bzw. elastisch verbiegbaren Rastabschnitten wird eine Rastkraft im Verbindungsbereich dauerhaft bereitgestellt. Die verbiegbaren Rastabschnitte ermöglichen ein selbsttätiges Einrichten der Rastverbindung an entsprechenden Gegenabschnitten der Wandelemente. Unter Aufbringung einer entsprechenden Gegenkraft gegen die wirksame Federkraft der Rastabschnitte im Verbindungszustand kann eine Rastverbindung einfach wieder gelöst werden, wobei die Rastabschnitte in eine Richtung entgegen der Richtung beim Einrichten der Rastverbindung ausfedern.With the particular spring-like or elastically bendable latching sections a latching force is permanently provided in the connection area. The bendable latching sections allow an automatic setting of the latching connection at corresponding opposite sections of the wall elements. By applying a corresponding counterforce against the effective Spring force of the latching portions in the connection state, a latching connection can be easily solved again, wherein the latching portions in a direction against the direction when setting the latching connection rebound.

So tritt im verbundenen Zustand das Verbindungselement nicht in Erscheindung bzw. bleibt verdeckt. Ein zu den eigentlichen Wandelementen zusätzliches bzw. angesetztes Zwischenelement, das im zusammengebauten Zustand einen Abschnitt der sichtbaren Teile der Schubladenwand bildet bzw. die Wandelemente ergänzt, ist vorteilhafterweise nicht notwendig. Eine Schublade mit einem Eckbereich mit stumpf anstoßenden Bereichen kann z. B. außerdem unter Designaspekten vorteilhaft sein.Thus, in the connected state, the connecting element does not appear or remains hidden. A to the actual wall elements additional or attached intermediate element that forms a portion of the visible parts of the drawer wall or complements the wall elements in the assembled state, is advantageously not necessary. A drawer with a corner area with blunt abutting areas can, for. B. also be advantageous in design aspects.

Mit dem erfindungsgemäßen Verbindungselement kann zudem vorteilhafterweise eine positionsrichtige Ausrichtung der beiden Wandelemente im zusammengebauten Zustand eingerichtet werden. Denn das Verbindungselement ist so an den beiden Wandelementen anbringbar, dass mit dem verrasteten Verbindungselement durch die betreffende Stirnseite und die betreffende Flächenseite im zusammengebauten Zustand nur eine vorgegebene Relativstellung möglich ist und die Stirnseite und die Flächenseite flächig beziehungsweise gegebenenfalls nahezu im Formschluss aneinander anliegen. Dies ermöglicht zudem eine hohe Abstützwirkung, wobei die Stirnseite über nahezu ihre gesamte Oberfläche in Anlage mit einem entsprechenden Teil der Oberfläche der Flächenseite ist. Dies erhöht die Stabilität der Schublade.With the connecting element according to the invention can also advantageously a positionally correct orientation of the two wall elements are set up in the assembled state. For the connecting element is attached to the two wall elements, that with the latched connection element by the relevant end face and the relevant surface side in the assembled state, only a predetermined relative position is possible and the face and the face side lie flat or possibly almost in positive engagement with each other. This also allows a high supporting effect, wherein the end face over almost its entire surface in contact with a corresponding part of the surface of the surface side. This increases the stability of the drawer.

Für eine flexible Wahl, welches der zu verbindenden Wandelemente stirnseitig und welches flächenseitig verbunden wird, kann es vorteilhafterweise eingerichtet werden, dass an einem Wandelement sowohl stirnseitig als auch flächenseitig vorbereitet Abschnitte vorhanden sind, an denen das Verbindungselement verrastbar ist.For a flexible choice, which is connected to the wall elements to be connected frontally and which surface side, it can be advantageously arranged that on a wall element both frontally and surface prepared sections are present at which the connecting element can be latched.

Bevorzugt ist das Verbindungselement ausgebildet, die zu verbindenden Wandelemente in einem Bereich zu verbinden, welcher im verbundenen Zustand der Wandelemente einen Eckbereich der Schublade bildet. Im Eckbereich sind die Wandelemente ohnehin benachbart. Mit dem Eckbereich ist in der Regel auch eine Trennstelle der Wandelemente vorhanden, insbesondere bei plattenförmigen Wandelementen, was vorteilhaft ist, so dass im Eckbereich auch Kräfte zwischen den Wandelementen übertragen werden müssen. An der im Eckbereich zwangsweise vorhandenen Schwachstelle kann das Verbindungselement effektiv stabilisierend wirken.Preferably, the connecting element is designed to connect the wall elements to be connected in a region which forms a corner region of the drawer in the connected state of the wall elements. In the corner, the wall elements are adjacent anyway. As a rule, a separation point of the wall elements is also present with the corner region, in particular in the case of plate-shaped wall elements, which is advantageous, so that forces must also be transmitted between the wall elements in the corner region. At the weak point forcibly present in the corner area, the connecting element can effectively stabilize.

Es ist überdies vorteilhaft, dass das Verbindungselement derart ausgestaltet ist, die Rastverbindung durch Einschnappen wenigstens eines Rastabschnitts in einen auf den Rastabschnitt abgestimmten Aufnahmeabschnitt eines zu verbindenden Wandelements auszubilden. Dabei schnappt der wenigstens eine Rastabschnitt an einem Wandelement ein, wobei wenigstens ein weiterer Rastabschnitt mit einem Aufnahmeabschnitt am anderen zu verbindenden Wandelement einschnappen kann. Bevorzugt sind jeweils genau zwei Rastabschnitte für das Einschnappen an Aufnahmeabschnitten jedes der beiden zu verbindenden Wandelemente vorgesehen, also an einem Verbindungselement insgesamt vier Rastabschnitte, für die zwei Wandelemente.It is also advantageous that the connecting element is designed such that form the latching connection by snapping at least one latching portion in a matched to the latching portion receiving portion of a wall element to be connected. In this case, the at least one latching section snaps against a wall element, wherein at least one further latching section can snap with a receiving section on the other wall element to be connected. Preferably, in each case exactly two latching sections are provided for snapping on receiving sections of each of the two wall elements to be connected, that is, on a connecting element a total of four latching sections, for the two wall elements.

Mit einem Einschnappmechanismus kann eine Rastverbindung besonders einfach und zuverlässig eingerichtet und gegebenenfalls wieder gelöst werden. Außerdem ist bei einem als Einschnappmechanismus gebildeten Rastmechanismus eine Rast- bzw. Einschnappkraft bzw. Verbindungskraft über die eingerichtete Rastverbindung ohne Weiters vorgebbar. Die Verbindungs- bzw. Rastkraft kann abhängig vom Material, der Form und/oder der Abmessung der Rastabschnitte beeinflusst bzw. vorgegeben werden.With a snap-in mechanism, a latching connection can be set up particularly easily and reliably and, if necessary, released again. In addition, a latching or Einschnappkraft or connecting force on the established locking connection without further predetermined in a detent mechanism formed as a snap mechanism. The connection or latching force can be influenced or specified depending on the material, the shape and / or the dimension of the latching sections.

Vorteilhafterweise ist es akustisch wahrnehmbar, wenn der wenigstens eine Rastabschnitt positionsrichtig einschnappt, so dass ein Monteur eine Rückmeldung bekommt, ob die Rastverbindung richtig und vollständig eingerichtet ist.Advantageously, it is acoustically perceptible when the at least one latching section snaps in the correct position, so that a mechanic receives feedback, whether the Locking connection is properly and completely set up.

Vorteilhafterweise ist das Verbindungselement ausgestaltet, wahlweise eine Front- oder Rückwand mit einer Seitenwand zu verbinden. Somit lässt sich äußerst flexibel das Verbindungselement für den Zusammenbau sämtlicher Wandelemente einer Schublade einsetzen. Es ist lediglich dafür Sorge zu tragen, dass für ein Verbindungselement passend vorbereitete Aufnahmeabschnitte an den entsprechenden Wandelementen, also an der Front-, Seiten- bzw. Rückwand vorgesehen sind.Advantageously, the connecting element is configured to selectively connect a front or rear wall with a side wall. Thus, the connecting element can be used extremely flexibly for the assembly of all wall elements of a drawer. It is only necessary to ensure that for a connecting element suitably prepared receiving portions are provided on the corresponding wall elements, ie on the front, side or rear wall.

Weiter wird vorgeschlagen, dass das Verbindungselement ausgebildet ist, um wahlweise eine rechts- oder linksseitig vorhandene Seitenwand mit einer Front- oder Rückwand zu verbinden. Auch dies erhöht eine flexible Anwendung des Verbindungselements für entsprechende Schubladen.It is further proposed that the connecting element is designed to selectively connect a right or left side existing side wall with a front or rear wall. This also increases a flexible application of the connecting element for corresponding drawers.

Besonders vorteilhaft ist es, wenn für sämtliche Verbindungen der Wandelemente solche Verbindungselemente verwendet werden können, die alle identisch gestaltet sind.It is particularly advantageous if, for all connections of the wall elements, such connection elements can be used, which are all designed identically.

Gemäß einer vorteilhaften Modifikation des Erfindungsgegenstands weist das Verbindungselement wenigstens zwei getrennt voneinander wirksame Rastabschnitte für jedes der zu verbindenden Wandelemente auf. Mit insbesondere genau zwei getrennt voneinander wirksamen Rastabschnitten für die Verbindung mit einem der beiden zu verbindenden Wandelemente kann eine mechanisch stabile und trotzdem noch einfache Ausbildung der Verbindungsanordnung realisiert werden. Für eine hohe Stabilität der Verbindung mit dem Verbindungselement sind beide miteinander zu verbindenden Wandelemente über jeweils mindestens zwei getrennt voneinander wirksame Rastabschnitte versorgt. Außerdem kann bei Versagen eines der wenigstens zwei getrennten Rastabschnitte die Funktion des Verbindungselements zumindest teilweise erhalten bleiben, indem der wenigstens eine weitere Rastabschnitt wirksam bleibt.According to an advantageous modification of the subject invention, the connecting element has at least two mutually effective latching portions for each of the wall elements to be connected. With in particular exactly two mutually effective latching sections for connection to one of the two wall elements to be connected, a mechanically stable and still simple design of the connection arrangement can be realized. For a high stability of the connection with the connecting element, both wall elements to be connected to one another are supplied via at least two mutually separate latching sections. In addition, in case of failure of at least two separate latching sections, the function of the connecting element at least partially retained by the at least one further latching section remains effective.

Außerdem kann ein zur Verrastung dienender Bereich, in welchem das Verbindungselement in Kontakt mit den entsprechenden Wandelementen ist, über zwei getrennt wirksame Rastabschnitte bzw. am Rand des Verbindungselements positionierten Rastabschnitten, größer gewählt werden, was die Stabilität der Verbindung weiter erhöht.In addition, a serving for latching area, in which the connecting element in contact with the corresponding wall elements is selected to be larger by means of two separately effective latching sections or latching sections positioned at the edge of the connecting element, which further increases the stability of the connection.

Bevorzugt ist ein Rastabschnitt ausgebildet, im verrasteten Zustand durch eine Öffnung in der Flächenseite durchzugreifen, um mit einer hinter der Öffnung liegenden Aussparung die Verrastung einzurichten. Mit dem Verrasten und der dabei wirksamen Rastkraft können Abschnitte des Verbindungselements sozusagen an das Wandelement bzw. die Flächenseite herangezogen werden, was die Verbindung stabilisiert. Mit dem Verrasten kann ggf. auch ein Verspannen des Verbindungselements erreicht werden.Preferably, a latching portion is formed to reach through in the latched state through an opening in the surface side in order to establish the latching with a recess located behind the opening. With the latching and the thereby effective latching force portions of the connecting element can be used so to speak to the wall element or the surface side, which stabilizes the connection. With the latching can also be achieved if necessary, a distortion of the connecting element.

Die Aussparung stellt eine vorteilhafte Ausgestaltung des auf den Rastabschnitt abgestimmten Aufnahmeabschnitts dar. Eine Aussparung kann z. B. eine Öffnung und/oder eine Vertiefung umfassen. Mit der Öffnung in der Flächenseite und der weiter innen bzw. im Inneren des Wandelements liegenden Aussparung wird eine besonders kompakte Verbindungsanordnung realisiert. Außerdem können neben dem in die Aussparung einrastbaren Rastabschnitt weitere Abschnitte des Verbindungselements und des Wandelements zusammenwirken und die Verbindungsstabilität dadurch erhöhen. Zum Beispiel indem Abschnitte des Verbindungselements, die nicht in das Innere des Wandelement greifen, an Gegenabschnitten außen an der Flächenseite des Wandelements zur Anlage kommen, beispielsweise sich an Bereichen abstützen, welche sich an die Öffnung in der Flächenseite anschließen. Mit dem Verrasten wird damit eine richtige Position des Verbindungselement erreicht, was eine exakte Positionierung der Wandelemente zueinander im verbundenen Zustand garantiert. Die beiden Wandelemente lassen sich insbesondere nur bei einem positionsrichtigen Einrasten des Rastabschnitts an der Aussparung miteinander stabil verbinden. Insgesamt kann mit der vorgeschlagenen Anordnung eine kippsichere bzw. biegestabile und versteifende Verbindung der Wandelement eingerichtet werden.The recess is an advantageous embodiment of the matched to the locking portion receiving portion. A recess may, for. B. include an opening and / or a depression. With the opening in the surface side and the recess located farther in or inside the wall element, a particularly compact connection arrangement is realized. In addition, in addition to the latchable in the recess portion latching portions of the connecting element and the wall element cooperate and thereby increase the connection stability. For example, by portions of the connecting element, which do not engage in the interior of the wall element, come to abut against outer portions on the outside surface of the wall element, for example, be supported on areas which adjoin the opening in the surface side. With the latching a correct position of the connecting element is thus achieved, which guarantees an exact positioning of the wall elements to each other in the connected state. In particular, the two wall elements can be connected to one another in a stable manner only when the latching section engages in the recess at the correct position. Overall, with the proposed arrangement, a non-tilting or bending-stable and stiffening connection of the wall element can be established.

Es ist überdies vorteilhaft, dass das Verbindungselement relativ zueinander aufspreizbare Verankerungsabschnitte aufweist, welche durch Aufspreizung mittels eines bewegbaren Einstellteils eine Klemmwirkung für die Verbindung der zu verbindenden Wandelemente entfalten. Mit einer solchen Anordnung kann auf engstem Raum sehr stabil und zuverlässig die Rastverbindung über das Verbindungselement realisiert werden. Dabei ist es besonders vorteilhaft, wenn zwei Verankerungsabschnitte mit jeweils einem Paar aufspreizbarer Anlagebacken vorhanden sind, wobei ein Paar der Anlagebacken durch das Einstellteil aus einer neutralen Stellung in eine um einen Spreizwinkel aufspreizbare Raststellung bringbar ist. Das Einstellteil kann hierzu zwischen die Spreizbacken geschoben oder eingeschraubt werden und in der Endstellung dabei festgeklemmt zwischen den auseinander gedrängten Anlagebacken fixiert sein. Die aufspreizbaren Verankerungsabschnitte sind vorteilhafterweise ausgebildet, im Verbindungszustand in Öffnungen bzw. Ausnehmungen der Flächenseite eines der zu verbindenden Wandelemente zu verrasten bzw. zu verklemmen. Die Ausnehmung kann vorteilhafterweise durch eine im Querschnitt U-förmige Vertiefung im Wandelement gebildet sein. Im Verbindungszustand sind weitere Abschnitte des Verbindungselements in der Stirnseite des anderen Wandelements verrastet oder andersartig fixiert.Moreover, it is advantageous that the connecting element has anchoring sections which can be spread apart relative to one another and which by spreading open by means of a movable adjusting part develop a clamping action for the connection of the wall elements to be connected. With such an arrangement can be realized in a confined space very stable and reliable latching connection via the connecting element. It is particularly advantageous if two anchoring sections are each provided with a pair of aufspreizbarer abutment jaws, wherein a pair of abutment jaws can be brought by the adjustment of a neutral position in a spreadable by a spread angle detent position. For this purpose, the adjusting part can be pushed or screwed in between the spreading jaws and, in the end position, clamped tightly between the clamping-apart bearing jaws. The expandable anchoring portions are advantageously designed to lock in the connection state in openings or recesses of the surface side of one of the wall elements to be connected or jammed. The recess may advantageously be formed by a cross-sectionally U-shaped depression in the wall element. In the connection state, further sections of the connecting element are latched or otherwise fixed in the end face of the other wall element.

Es wird weiter vorgeschlagen, dass das Verbindungselement ausgestaltet ist, eine Verbindung mit der Stirnseite des Wandelements über eine Spreizdübelanordnung zu realisieren. Eine vorteilhafte Ausgestaltung mit aufspreizbaren Verankerungsabschnitten ist beispielsweise eine so genannte Spreizdübelanordnung. Über eine Spreizdübelanordnung kann auf engstem Raum eine starke Verrastung eingerichtet werden.It is further proposed that the connecting element is designed to realize a connection with the end face of the wall element via a Spreizdübelanordnung. An advantageous embodiment with expandable anchoring sections is, for example, a so-called expansion dowel arrangement. About a Spreizdübelanordnung can be set up in a confined space a strong locking.

Weiter wird vorgeschlagen, dass das Verbindungselement Hakenmittel umfasst, mit denen durch Einkrallen in einem Wandelement eine nicht zerstörungsfrei lösbare Rastverbindung zwischen dem Verbindungselement und dem betreffenden Wandelement ausbildbar ist. So kann das Verbindungselement besonders stabil und dauerhaft an einem Wandelement verankert werden.It is further proposed that the connecting element comprises hook means with which by notching in a wall element a non-destructively releasable latching connection between the connecting element and the relevant Wall element can be formed. Thus, the connecting element can be anchored particularly stable and durable on a wall element.

Es ist überdies vorteilhaft, dass das Verbindungselement eine Abmessung aufweist, sodass im Verbindungszustand Abschnitte des Verbindungselements einen freien Innenbereich zwischen zwei Außenseiten des zu verbindenden Wandelements zumindest im Wesentlichen ausfüllen. Das Verbindungselement kann in einem Innenfreiraum zwischen gegenüberliegenden Außenseiten der zu verbindenden Wandelemente untergebracht werden.It is also advantageous that the connecting element has a dimension, so that in the connecting state portions of the connecting element at least substantially fill a free inner region between two outer sides of the wall element to be connected. The connecting element can be accommodated in an internal space between opposite outer sides of the wall elements to be connected.

Besonders vorteilhaft ist es, dass ein Aufsteckteil am Verbindungselement vorhanden ist, wobei das Aufsteckteil Widerhakenmittel aufweist, um das mit dem Aufsteckteil versehene Verbindungselement an einem Wandelement zu verhaken. So kann ein Verbindungselement mit Widerhakenmittel für eine besonders stabile Fixierung an einem Wandelement versehen werden.It is particularly advantageous that a plug-on part is provided on the connecting element, wherein the plug-on part has barb means in order to hook the connecting element provided with the plug-on part to a wall element. Thus, a connecting element can be provided with a barb means for a particularly stable fixation on a wall element.

Die Widerhakenmittel sind insbesondere zusätzlich oder alternativ zu den Rastabschnitten am Verbindungselement vorhanden.The barbs are in particular additionally or alternatively to the locking portions on the connecting element available.

Vorteilhafterweise ist das Verbindungselement für eine Verbindung von aus Profilmaterial bestehenden Wandelementen ausgebildet. Mit den Verbindungselementen können insbesondere profilierte Wandelemente, die im Hinblick auf die Materialwahl, ein geringes Gewicht bzw. zur Materialeinsparung vorteilhaft sind, genutzt werden. Bevorzugt sind die Verbindungselemente exakt auf entsprechende Aufnahmeabschnitte der Wandelemente abgestimmt.Advantageously, the connecting element is designed for a connection of wall elements consisting of profiled material. In particular profiled wall elements, which are advantageous in terms of the choice of material, a low weight and material savings, can be used with the connecting elements. Preferably, the connecting elements are matched exactly to corresponding receiving portions of the wall elements.

Die Erfindung betrifft außerdem eine Schublade mit einer Schubladenwand aus miteinander verbundenen Wandelementen, wobei die Schubladenwand eine Frontwand, eine Rückwand und/oder wenigstens eine Seitenwand umfasst. Erfindungsgemäß ist eine der oben genannten Vorrichtungen an der Schublade vorhanden. So lassen sich die oben genannten Vorteile bei einer Schublade realisieren.The invention also relates to a drawer with a drawer wall of interconnected wall elements, wherein the drawer wall comprises a front wall, a rear wall and / or at least one side wall. According to the invention, one of the above-mentioned devices is present on the drawer. This is how the above advantages can be added realize a drawer.

Bevorzugt sind die Wandelemente miteinander durch stumpfes Anstoßen einer Stirnseite eines Wandelements an einer Flächenseite eines angrenzenden Wandelements verbunden. Insbesondere ist eine Rückwand mit ihrer Stirnseite bzw. mit ihren beiden Stirnseiten an einer innen liegenden Flächenseite von Seitenwänden der Schublade bündig anstoßen. Dabei bildet eine Flächenseite der Rückwand bzw. der Frontwand mit jeweiligen Stirnseiten der Seitenelemente eine hintere bzw. vordere Schmalseite der Schublade.Preferably, the wall elements are connected to one another by blunt abutment of an end face of a wall element on a surface side of an adjacent wall element. In particular, a rear wall with its front side or with its two end faces abut flush on an inner surface side of side walls of the drawer. In this case forms a surface side of the rear wall or the front wall with respective end faces of the side elements a rear or front narrow side of the drawer.

Figur 1 zeigt ein als Steckverbinder bzw. Doppelclip 1 ausgebildetes Verbindungselement aus Kunststoff. Der Doppelclip 1 ist Teil eines intelligenten Verbindungssystems für Schubladen bzw. Schubkästen, die aus Profilmaterial ablängbaren Wandelementen aufgebaut sind. Die Wandelemente können aus einem Metallmaterial zum Beispiel Aluminium bestehen und alle aus dem gleichen Profil durch Ablängen hergestellt sein. Mit dem Doppelclip 1 kann eine doppelte Steckverbindung bzw. eine auf zwei Seiten eingerichtete Clipverbindung eingerichtet werden. Der Doppelclip 1 kann für die Verbindung von zwei Wandelementen 2, 3 in einer gemäß Figur 2 gezeigten Verbindungsposition verwendet werden. FIG. 1 shows a trained as a connector or double clip 1 connecting element made of plastic. The double clip 1 is part of an intelligent connection system for drawers or drawers, which are constructed of profile material ablängbaren wall elements. The wall elements may be made of a metal material, for example aluminum, and all made from the same profile by cutting to length. The double clip 1 can be used to set up a double connector or a two-sided clip connection. The double clip 1 can for the connection of two wall elements 2, 3 in a according FIG. 2 shown connection position can be used.

Die Clipverbindung mit dem Doppelclip 1 wird dadurch eingerichtet, dass der Doppelclip 1 in einer Seitenwand 2 bzw. einer Seitenzarge einer Schublade eingesteckt wird und anschließend zusammen mit der Seitenwand 2 an einer Frontwand 3 bzw. einem Frontprofil befestigt wird, durch Einstecken und Verrasten des Doppelclip 1 an der Frontwand 3.The clip connection with the double clip 1 is set up by inserting the double clip 1 in a side wall 2 or a side frame of a drawer and then fastening it together with the side wall 2 to a front wall 3 or a front profile by inserting and locking the double clip 1 on the front wall 3.

Der einstückige Doppelclip 1 ist klein bauend und weist einen flachen und streifenförmig ausgebildeten Steg 4 auf. Am Steg 4 sind zwei gegenüberliegende Hauptseiten 4a und 4b vorhanden. An der Hauptseite 4a stehen in Längsrichtung des Stegs 4 betrachtet an gegenüberliegenden Enden widerhakenartige Federlaschen 5 und 6 vor. Die Federlaschen 5, 6 weisen jeweils eine zur Hauptseite 4a senkrecht abstehende Zunge 7 und einen in Richtung der Hauptseite 4a schräg abgewinkelt umgebogenen Rastabschnitt 8 auf. Der Rastabschnitt 8 ist über eine Umbiegung gegenüber der Zunge 7 elastisch federnd vorhanden, sodass die Rastabschnitte 8 an den Federlaschen 5 und 6 aus der in Figur 1 gezeigten neutralen bzw. unbelasteten Position gemäß dem Bewegungspfeil P1 in Richtung zur Zunge 7 ausfedern kann. Auch die Zunge 7 kann geringfügig gegenüber dem Steg 4 elastisch ausfedern. Für eine Verrastung des Doppelclip 1 an der Seitenwand 2 sind an der Seitenwand 2 in einer zu einem Schubladeninneren gerichteten Innenwand 2a entsprechend dem Abstand der Federlaschen 5, 6 am Steg 4 rechteckförmige Öffnungen 9 und 10 vorhanden. Die Öffnungen 9 und 10 weisen eine Breite auf, welche der Breite B1 der Federlaschen 5, 6 entspricht, quer zur Längserstreckung des Stegs 4 betrachtet. Ein geringfügiges Spiel zwischen den Federlaschen 5, 6 und den Öffnungen 9, 10 kann dabei vorhanden sein, sodass die Federlaschen 5, 6 problemlos in die Öffnungen 9, 10 einsteckbar und ggf. wieder lösbar sind. Beim Einstecken und Lösen müssen die Rastabschnitte 8 etwas in Richtung der Pfeile P1 federnd zusammengedrückt werden, um durch die Öffnungen 9, 10 zu passen. Nach dem Einstecken werden die Rastabschnitte 8 wieder zurück entgegen der Pfeilrichtung P1 federn, sodass die Rastabschnitte 8 innen an den Öffnungen 9, 10 hintergreifend verrastet sind. Eine Höhe der Öffnungen 9, 10 ist etwas geringer als eine Höhe H1 der Federlaschen 5, 6 im unbelasteten Zustand gemäß Figur 1, wobei die Höhe H1 sich am vorderen der Hauptseite 4a zugewandten Ende der Rastabschnitte 8 ergibt.The one-piece double clip 1 is small and has a flat and strip-shaped web 4. At the web 4 two opposite main sides 4a and 4b are present. On the main side 4a are viewed in the longitudinal direction of the web 4 at opposite ends barb-like spring tabs 5 and 6 before. The spring tabs 5, 6 each have a main side 4a perpendicularly projecting tongue 7 and an obliquely angled in the direction of the main side 4a latching portion 8 on. The locking portion 8 is elastically resiliently provided via a bend relative to the tongue 7, so that the locking portions 8 on the spring tabs 5 and 6 from the in FIG. 1 shown neutral or unloaded position according to the movement arrow P1 in the direction of the tongue 7 can rebound. Also, the tongue 7 can spring slightly elastic against the web 4. For a locking of the double clip 1 on the side wall 2 are provided on the side wall 2 in an inner wall 2 a directed to a drawer interior according to the distance of the spring tabs 5, 6 on the web 4 rectangular openings 9 and 10. The openings 9 and 10 have a width which corresponds to the width B1 of the spring tabs 5, 6, viewed transversely to the longitudinal extent of the web 4. A slight play between the spring tabs 5, 6 and the openings 9, 10 may be present, so that the spring tabs 5, 6 easily in the openings 9, 10 can be inserted and possibly released again. When inserting and releasing the locking portions 8 must be slightly compressed in the direction of the arrows P1 resiliently to fit through the openings 9, 10. After insertion, the latching portions 8 are spring back again against the direction of arrow P1, so that the latching portions 8 are latched inwardly at the openings 9, 10 engage behind. A height of the openings 9, 10 is slightly less than a height H1 of the spring tabs 5, 6 in the unloaded state according to FIG. 1 , wherein the height H1 results at the front of the main side 4a facing the end of the locking portions 8.

Wird nun beim Zusammenbau der Schublade bzw. der Seitenwand 2 und der Frontwand 3 der Doppelclip 1 mit seinen Federlaschen 5, 6 in die Öffnungen 9 und 10 der Seitenwand 2 eingesteckt, liegt im verrasteten Zustand die Hauptseite 4a flächig an der Innenwand 2a der Seitenwand 2 an, was insbesondere Figur 2 und Figur 3 verdeutlichen.If, when assembling the drawer or the side wall 2 and the front wall 3, the double clip 1 with its spring tabs 5, 6 is inserted into the openings 9 and 10 of the side wall 2, the main side 4a lies flat against the inner wall 2a of the side wall 2 in the latched state in particular FIG. 2 and FIG. 3 clarify.

Zur Verbindung der Seitenwand 2 mit dem eingesteckten Doppelclip 1 mit der Frontwand 3 ist die Verrastung über den Doppelclip 1 durch federnde Klammern 11 und 12 des Doppelclip 1 einrichtbar. Die Klammern 11, 12 stehen auf der Hauptseite 4b gegenüberliegend zu den Federlaschen 5, 6 senkrecht an der Hauptseite 4b über. Die Klammern 11, 12 weisen hierbei einen mit der Breite B2 des Stegs 4 verlaufenden Klammerkörper 13 auf. Am Klammerkörper 13 ist jeweils eine Einrastnase 14 vorhanden, wobei die Einrastnasen 14 in Längsrichtung des Stegs 4 bzw. nach außen am Doppelclip 1 vorstehend ausgebildet sind.To connect the side wall 2 with the inserted double clip 1 with the front wall 3, the latching on the double clip 1 by resilient clamps 11 and 12 of the double clip 1 can be set. The brackets 11, 12 are on the main side 4b opposite to the spring tabs 5, 6 perpendicular to the main side 4b over. The brackets 11, 12 in this case have a running with the width B2 of the web 4 bracket body 13. In each case one latching lug 14 is provided on the clamp body 13, wherein the latching lugs 14 are formed protruding in the longitudinal direction of the web 4 or outwardly on the double clip 1.

Aus der in Figur 1 gezeigten neutralen Position der Klammern 11, 12 können diese elastisch nach innen gemäß der Pfeile P2 ausfedern, sodass durch zusammenstecken der Frontwand 3 und der Seitenwand 2 mit dem darin untergebrachten Doppelclip 1 diese lösbar verbunden werden können. Die Einrastnasen 14 greifen hierbei in entsprechend dazu passende Öffnungen 15 und 16 innen in der Frontwand 3. Die Öffnungen 15, 16 sind gegenüber in gegenüberliegenden parallel in Längsrichtung der Frontwand 3 verlaufenden vorstehenden Stegen 17, 18 vorhanden. Ein Abstand A1 von einer Stirnseite 19 der Frontwand 3 bis zum Rand der Öffnung 15, 16 entspricht zumindest nahezu einer Abmessung A2 am Doppelclip 1, zwischen der Hauptseite 4a und einem Absatz an der Einrastnase 14. Damit sind gemäß Figur 2 die Seitenwand 2 und die Frontwand 3 fest verbunden.From the in FIG. 1 shown neutral position of the brackets 11, 12, these can resiliently rebound inwardly according to the arrows P2, so that by plugging the front wall 3 and the side wall 2 with the housed therein double clip 1 they can be detachably connected. The snap-in lugs 14 engage in corresponding openings 15 and 16 inside the front wall 3. The openings 15, 16 are opposite in parallel opposite in the longitudinal direction of the front wall 3 extending ridges 17, 18 are present. A distance A1 from an end face 19 of the front wall 3 to the edge of the opening 15, 16 corresponds at least almost to a dimension A2 on the double clip 1, between the main side 4a and a shoulder on the latching nose 14. Thus, according to FIG FIG. 2 the side wall 2 and the front wall 3 firmly connected.

Die Positionierung der Öffnungen 9, 10 in Längsrichtung der Seitenwand 2 betrachtet ist so gewählt, dass im gemäß Figur 2 und Figur 3 zusammengebauten Zustand der Seitenwand 2 und der Frontwand 3 eine Stirnseite 2b der Seitenwand 2 bündig verläuft zu einer Außenseite der Frontwand 3. In Figur 3 weist die Frontwand 3 keine durchgehende flächige Außenseite auf, sondern nur streifenförmige Schmalseiten von Stegen der Frontwand 3, zu denen auch die Stege 17 und 18 gehören.The positioning of the openings 9, 10 viewed in the longitudinal direction of the side wall 2 is chosen so that in accordance with FIG. 2 and FIG. 3 assembled state of the side wall 2 and the front wall 3 a face 2b of the side wall 2 is flush with an outside of the front wall 3. In FIG. 3 The front wall 3 does not have a continuous flat outside, but only strip-shaped narrow sides of webs of the front wall 3, to which the webs 17 and 18 also belong.

Für ein leichtes Verrasten durch Aufschieben mit einer Stirnseite der Frontwand 3 senkrecht zur Innenwand 2a der Seitenwand 2 mit dem Doppelclip 1 sind die Einrastnasen 14 jeweils auf ihrer zum freien Ende der Klammern 11, 12 gerichteten Seite mit einer Anschrägung 14a versehen. So können die Enden der Stege 17 und 18 gegen die Anschrägungen 14a stoßen und bei weiterem Aufschieben Klammern 11, 12 etwas gemäß P2 ausweichen bis die Klammern mit den Einrastnasen 14 in die Öffnungen 15, 16 einschnappen und dort hintergreifend verrasten.For easy latching by sliding with a front side of the front wall 3 perpendicular to the inner wall 2a of the side wall 2 with the double clip 1, the latching lugs 14 are each provided on their free end of the brackets 11, 12 side facing with a bevel 14a. Thus, the ends of the webs 17 and 18 abut against the chamfers 14a and on further pushing clips 11, 12 dodge slightly in accordance with P2 until the brackets snap with the latching lugs 14 in the openings 15, 16 and engage behind engaging.

Figur 4 zeigt ein weiteres erfindungsgemäßes Verbindungselement 20, welches ebenfalls stirnseitig an einem Wandelement bzw. einer Schubladenwand einbringbar ist, wobei im verbundenen Zustand der Wandelemente die Stirnseite an einer Flächenseite des anderen Wandelements anliegt. Das Verbindungselement 20 umfasst einen Grundkörper 21 insbesondere aus Kunststoff, an dem ein Krallblech 22 aufgeschoben vorhanden ist. Das U-förmige Krallblech 22 kann von einer Seite auf den Grundkörper 21 aufgeschoben werden und im Bereich einer nach unten abgesetzten Aufnahmekontur 23 positionsrichtig am Grundkörper 21 fixiert werden. Hierzu sind Rundlöcher 24 und gegenüberliegende Rundlöcher 25 an gegenüberliegenden Schenkeln des Krallblechs 22 eingebracht. Die Rundlöcher 24, 25 sind im aufgesteckten Zustand gemäß Figur 4 über außen entsprechend dimensionierte überstehende Rundsockel 26 in der Aufnahmekontur 23 verrastbar.
