Abstract

A frame, more particularly for a picture, comprises profiled rails which are joined together at the corners of the frame by a corner-connector. Each corner-connector comprises two plugs arranged respectively in a cavity in each profiled rail, and each of the cavities comprises an opening extending in the longitudinal direction. The object to be achieved is a functionally reliable joint between the profiled rails which is simple to produce and can easily be released when required. To this end, each plug comprises a tongue which passes through the opening in the cavity and which engages, by means of a hook element or the like, behind a retaining element. A retaining element of this kind is arranged on at least one web of the profiled rail.

Description

Die Erfindung betrifft einen Rahmen, insbesondere für ein Bild, gemäß den im Oberbegriff des Patentanspruchs 1 angegebenen Merkmalen.The invention relates to a frame, in particular for a picture, according to the features specified in the preamble of claim 1.

Aus der französischen Patentanmeldung 2 322 572 ist ein derartiger Rahmen nachgewiesen, der zur Aufnahme eines Gemäldes einer Reproduktion, Fotografie oder sonstigen Kunstgegenständen vorgesehen ist. Die Profilschienen enthalten eine im Querschnitt etwa rechteckförmige Hohlkammer, welche eine sich in Längsrichtung der Profilschiene erstreckende Öffnung zwischen zwei Stegen aufweist. Die Stege sind in der Nähe der jeweiligen Rahmenecke mit einer Ausnehmung versehen, in welche der Eckverbinder mit einem am freien Ende des Zapfens angeordneten Haken eingreift. Der Haken befindet sich ebenso wie der Zapfen im Inneren der Hohlkammer und die Spitze des Hakens ist aus der Hohlkammer heraus nach außen gerichtet. Beim Zusammenfügen der Profilschienen zu dem Rahmen können sich Schwierigkeiten ergeben wenn der Haken nicht ordnungsgemäß in die Ausnehmung des Steges eingreift. Es ist nicht ohne weiteres möglich, den festen Sitz der Eckverbinder zu überprüfen, da Zapfen und Haken in der Hohlkammer sich befinden und nur durch die Öffnung hindurch zugänglich sind. Es besteht die Gefahr, daß nach dem Zusammenbau der Haken versehentlich in die Hohlkammer eingedrückt und die Verbindung gelöst wird.From the French patent application 2 322 572, such a frame has been proven, which is intended for holding a painting of a reproduction, photography or other art objects. The profile rails contain a hollow chamber which is approximately rectangular in cross-section and which has an opening extending in the longitudinal direction of the profile rail between two webs. The webs are provided near the respective frame corner with a recess into which the corner connector engages with a hook arranged at the free end of the pin. The hook, like the pin, is located inside the hollow chamber and the tip of the hook is directed outwards from the hollow chamber. When assembling the profile rails into the frame, difficulties can arise if the hook does not engage properly in the recess of the web. It is not easily possible to check that the corner connectors are firmly seated since the pins and hooks are located in the hollow chamber and are only accessible through the opening. There is a risk that after the hooks have been assembled, they are accidentally pressed into the hollow chamber and the connection is released.

Aus der DE-OS 30 27 258 ist ein Wechselrahmen bekannt, dessen Eckverbinder außerhalb der Hohlkammer eine Zunge mit einem Haken aufweist. In der Hohlkammer ist der Zapfen angeordnet. Die Profilschiene weist eine Ausnehmung auf, in welche von außen her der Haken der Zunge eingreift. Die Zunge ist nicht vor äußeren Einwirkungen geschützt und ein unbeabsichtigtes Lösen der Verbindung kann nicht ausgeschlossen werden. Für den Eckverbinder ist ein nicht unerheblicher Materialaufwand erforderlich und in der Praxis ist ein Abreißen der freiliegenden Zungen zu befürchten.From DE-OS 30 27 258 an interchangeable frame is known, the corner connector of which has a tongue with a hook outside the hollow chamber. The pin is arranged in the hollow chamber. The profile rail has a recess into which the hook of the tongue engages from the outside. The tongue is not protected against external influences and an unintentional loosening of the connection cannot be excluded. A considerable amount of material is required for the corner connector and in practice there is a risk of the exposed tongues tearing off.

Aus dem DE-GM 76 33 157 ist ein Wechseirahmen bekannt, dessen Eckverbinder innerhalb der Hohlkammern jeweils den Zapfen sowie den Haken an einer nachgiebigen Zunge aufweisen. Der Haken greift von innen dem Hohlraum heraus in eine Aussparung der Profilschiene. Der ordnungsgemäße Sitz des Hakens kann beim Zusammenbau nicht ohne weiteres überprüft werden. Auch ist nicht auszuschließen, daß bei einem Aufhängen des Bildes versehentlich der Haken nach innen gedrückt wird und sich die Verbindung der Profilschienen löst.From DE-GM 76 33 157 an interchangeable frame is known, the corner connectors of which each have the pin and the hook on a flexible tongue within the hollow chambers. The hook reaches from the inside of the cavity into a recess in the profile rail. The correct position of the hook cannot be checked easily during assembly. It also cannot be ruled out that when the picture is hung up, the hook is accidentally pressed inwards and the connection of the profile rails is released.

Schließlich zeigt die DE-PS 29 42 555 einen Wechselrahmen, dessen Eckverbinder in der Hohlkammer der jeweiligen Profilschiene eine Zunge aufweist. Die Zunge weist eine der Rahmenecke zugewandte freie Stirnseite auf. Zu beiden Seiten der Zunge enthält der Eckverbinder schmale Befestigungsstege, wodurch eine relativ große Breite des Zapfens bedingt ist. Ferner kann der feste Sitz der Zunge nicht ohne weiteres überprüft werden und durch unbeabsichtigtes Hineindrücken der Zunge in die Kammer kann sich die Verbindung wieder lösen.Finally, DE-PS 29 42 555 shows an interchangeable frame, the corner connector of which has a tongue in the hollow chamber of the respective profile rail. The tongue has a free end face facing the corner of the frame. On both sides of the tongue, the corner connector contains narrow fastening webs, which means that the pin has a relatively large width. Furthermore, the tight fit of the tongue cannot be checked easily and the connection can be released again by inadvertently pressing the tongue into the chamber.

Der Erfindung liegt die Aufgabe zugrunde, den Rahmen der genannten Art dahingehend weiterzubilden, daß einerseits eine zuverlässige Verbindung erreicht wird und andererseits die Überprüfung der Verbindung ohne Schwierigkeiten vorgenommen werden kann. Ein unbeabsichtigtes Lösen der Verbindung beim Festhalten des Rahmens im Bereich der Rahmenecke soll vermieden werden und bei Bedarf soll die Verbindung auch ohne zusätzliche Werkzeuge wieder gelöst werden können. Der Eckverbinder soll mit geringem Materialeinsatz eine funktionssichere Verbindung gewährleisten, die bei Bedarf jedoch wieder leicht gelöst werden kann.The invention has for its object to develop the framework of the type mentioned in such a way that on the one hand a reliable connection is achieved and on the other hand the connection can be checked without difficulty. An unintentional loosening of the connection when holding the frame in the area of the frame corner should be avoided and, if necessary, the connection should be able to be released again without additional tools. The corner connector is intended to ensure a functionally reliable connection with a small amount of material, which, however, can be easily removed again if required.

Die Lösung dieser Aufgabe erfolgt gemäß den im Kennzeichen des Patentanspruchs 1 angegebenen Merkmalen.This object is achieved according to the features specified in the characterizing part of patent claim 1.

Besondere Ausführungsarten der Erfindung sind in den abhängigen Ansprüchen 2-12 aufgeführt.Particular embodiments of the invention are listed in dependent claims 2-12.

Der erfindungsgemäße Rahmen weist einen funktionsgerechten Aufbau auf, wobei eine zuverlässige Verbindung der Profilschienen in den Rahmenecken gewährleistet wird. Zur Herstellung der Verbindung werden keine besonderen Werkzeuge benötigt, sondern die Zunge des Halteelements kann manuell von dem Halteelement gelöst werden, wobei nachfolgend das Halteelement aus der Hohlkammer in deren Längsrichtung herausziehbar ist. Die Zunge des jeweiligen Zapfens durchdringt die sich in Längsrichtung der Hohlkammer erstreckende Öffnung und kann zur Herstellung der Verbindung problemlos über das Halteelement an den Steg der Profilschiene geschoben werden, um nachfolgend zuverlässig mit dem Haken einzuhaken. Die Zunge ist fest mit dem Zapfen verbunden, wobei eine hinreichende Bewegbarkeit gegeben ist, um die erfindungsgemäße Bewegbarkeit bezüglich des Halteelements zu ermöglichen. Beim Überschieben des Halteelements wird die Zunge mit einer von der Hohlkammer weggerichteten Kraft in Richtung zur Rückseite der Profilschiene bewegt. Nach dem Überschieben des Halteelements federt die Zunge zurück, und zwar in Richtung auf die Hohlkammer, wodurch eine zuverlässige Arretierung sichergestellt wird. Die Zunge weist zweckmäßig eine mit einem Finger in einfacher Weise zu untergreifende Nase auf, um bei Bedarf die Verbindung wieder in einfacher Weise lösen zu können. Hierbei muß die Zunge lediglich entgegen der Federwirkung über das Halteelement hochgehoben werden, so daß nachfolgend die Zunge und der ganze Eckverbinder aus dem Ende der Profilschiene herausgezogen werden kann. Aufgrund der erfindungsgemäß federelastischen Ausgestaltung, zumindest der Zunge und zweckmäßig auch des gesamten Eckverbinders, wird eine zuverlässige Verspannung der beiden Profilschienen im Eckbereich sichergestellt. Die auf Gehrung geschnittenen Profilschienen liegen folglich in den Eckbereireichen dicht beieinander, ohne daß hierbei störende Spalte in Erscheinung treten. Eine örtliche Überbeanspruchung und damit verbundene Verformung der Profilschiene, wie es bei Verwendung von Schraubelementen möglich ist, wird in zweckmäßiger Weise vermieden. Der Eckverbinder besteht zweckmäßig aus einem Kunststoff, wobei durch entsprechende Vorgabe der Materialdicke sowie der Länge der Zunge problemlos die Bewegbarkeit erreicht wird. Auch bei Ausbildung aus einem Metall, das eine hinreichende elastische Nachgiebigkeit aufweist, kann diese Bewegbarkeit problemlos gewährleistet werden. Die Halteelemente sind zweckmäßig durch Ausstanzen sowie Umbiegen aus den Stegen gebildet. Die Zunge ist im Rahmen der Erfindung federelastisch, und zwar aufgrund entsprechender Materialeigenschaften und/oder Formgebung.The frame according to the invention has a functionally appropriate structure, a reliable connection of the profile rails in the frame corners being ensured. No special tools are required to establish the connection, but the tongue of the holding element can be manually detached from the holding element, the holding element subsequently being able to be pulled out of the hollow chamber in its longitudinal direction. The tongue of the respective pin penetrates the opening extending in the longitudinal direction of the hollow chamber and can be easily pushed over the holding element to the web of the profile rail in order to make the connection, in order subsequently to hook reliably with the hook. The tongue is firmly connected to the pin, there being sufficient mobility to enable the inventive mobility with respect to the holding element. When the holding element is pushed over, the tongue is moved towards the rear of the profile rail with a force directed away from the hollow chamber. After the holding element has been pushed over, the tongue springs back, in the direction of the hollow chamber, thereby ensuring a reliable locking. The tongue expediently has a nose which can be gripped under with a finger in a simple manner in order to be able to detach the connection in a simple manner if necessary. Here, the tongue only has to be raised against the spring action via the holding element, so that the tongue and the entire corner connector can subsequently be pulled out of the end of the profile rail. Due to the spring-elastic design according to the invention, at least of the tongue and expediently also of the entire corner connector, a reliable bracing of the two profile rails in the corner area is ensured. The miter-cut profile rails are consequently close together in the corner areas, without the appearance of annoying gaps. Local overloading and the associated deformation of the profile rail, as is possible when using screw elements, is advantageously avoided. The corner connector suitably consists of an art fabric, whereby the mobility is easily achieved by appropriate specification of the material thickness and the length of the tongue. This mobility can also be ensured without any problems if it is formed from a metal which has sufficient elastic resilience. The holding elements are expediently formed by punching out and bending over from the webs. In the context of the invention, the tongue is resilient, specifically because of the corresponding material properties and / or shape.

Die Profilschienen 2 enthalten auf ihrer Rückseite zwei parallel zueinander in Längsrichtung verlaufende Stege 8, 10, zwischen welchen eine sich ebenfalls in Längsrichtung erstreckende Öffnung 12 vorhanden ist. Unter den Stegen 8, 10 der Profilschiene 2 befindet sich eine Hohlkammer, in welcher die orthogonal zueinander liegenden Zapfen 16, 18 des Eckverbinders von den Enden her eingeschoben sind. Die Eckverbinder 6 enthalten ferner an ihren Zapfen 16, 18 jeweils eine Zunge 20, welche ein Halteelement 22, 24 an den Stegen 8, 10 hintergreift. Die Halteelemente 22, 24 stehen etwas über die Stege 8, 10 in der Weise vor, daß die Zunge 20 über sie hinweggeschoben werden kann und mit seitlichen Haken 26, 28 hintergrieft. Es sei festgehalten, daß erfindungsgemäß sich die Zunge 20 mit den Haken 26, 28 von dem jeweiligen Ende der Profilschiene 2 weg bis über die Halteelemente 22, 24 erstreckt.Fig. 1 shows a plan view of the back of the frame, which is constructed from four rails 2. The profile rails 2 are mitred in the corners 4, a corner connector 6 being arranged in each corner in the profile rails. The profile rails 2 contain on their rear side two webs 8, 10 running parallel to one another in the longitudinal direction, between which there is an opening 12 which also extends in the longitudinal direction. Under the webs 8, 10 of the profile rail 2 there is a hollow chamber in which the pins 16, 18 of the corner connector, which are orthogonal to one another, are inserted from the ends. The corner connectors 6 also contain on their pins 16, 18 each a tongue 20 which engages behind a holding element 22, 24 on the webs 8, 10. The holding elements 22, 24 protrude slightly above the webs 8, 10 in such a way that the tongue 20 can be pushed over them and undercut with side hooks 26, 28. It should be noted that, according to the invention, the tongue 20 with the hooks 26, 28 extends away from the respective end of the profile rail 2 as far as over the holding elements 22, 24.

In den Rahmen ist eine Trägerplatte 30 für ein Bild eingesetzt, welches von der Vorderseite des Rahmens her betrachtet werden kann. Die Trägerplatte und folglich auch das Bild und ggfs. eine Glasplatte sind mittels Federelementen 32 in dem Rahmen gehalten.A support plate 30 for an image is inserted into the frame, which can be viewed from the front of the frame. The carrier plate and consequently also the picture and possibly a glass plate are held in the frame by means of spring elements 32.

Fig. 2 zeigt vergrößert einen Schnitt entlang Schnittlinie II gemäß Fig. 1. Man erkennt hier den Steg 8 und die unter bzw. vor diesem liegende Hohlkammer 14. In der Hohlkammer 14 befindet sich der Eckverbinder bzw. der Zapfen 16, an dessen Ende die Zunge 20 angeordnet ist. Die Zunge 20 greift durch die obengenannte Öffnung zwischen den Stegen hindurch und es ist hier am vorderen Ende der eine Haken 26 zu erkennen. Dieser Haken 26 hintergrieft, entsprechendes gilt auch für den anderen Haken, das Halteelement 22 des Steges 8. Das Halteelement ist einfach durch Ausstanzen und Umbiegen nach oben bzw. zur Rückseite 34 hergestellt worden.FIG. 2 shows an enlarged section along section line II according to FIG. 1. Here, the web 8 and the hollow chamber 14 located below or in front of it can be seen. In the hollow chamber 14 there is the corner connector or the pin 16, at the end of which the Tongue 20 is arranged. The tongue 20 reaches through the above-mentioned opening between the webs and one hook 26 can be seen here at the front end. This hook 26 engages behind, the same also applies to the other hook, the holding element 22 of the web 8. The holding element is simply produced by punching out and bending upwards or to the rear 34.

Das hier sichtbare Halteelement 22 steht ebenso wie das andere vor der Zeichenebene befindliche Halteelement nach außen über die Außenfläche 23 des Steges 8 vor. Die Zunge 20 ist zwischen den beiden Halteelementen aus der Hohlkammer 14 nach außen hindurchgeführt, so daß das freie Ende der Zunge 20 mit den beiden Haken sich über der Außenfläche 23 befindet. Die Haken hintergreifen mit ihren Eingriffsflächen die genannten Halteelemente außerhalb der Hohlkammer 14 und oberhalb der Außenflächen der beiden Stege. Die beiden Haken sind seitlich am vorderen Ende der Zunge angeordnet. Beim Herstellen der Verbindung gleiten die Haken zunächst über die Stege und die Halteelemente, wobei das freie Ende der Zunge eine von der Außenfläche der Stege weggerichtete Bewegung durchführt. Haben dann die Haken das Ende der Halteelemente erreicht, so kann eine in Richtung auf die Außenfläche 23 des Steges wirksame Kraft einwirken um die Haken mit den Halteelementen in Eingriff zu bringen und so die Verbindung zu fixieren. Falls infolge von Herstellungstoleranze die Haken nicht selbsttätig einrasten, so kann man ohne weiteres mit dem Finger auf die Haken von außen drücken, um die Verbindung herzustellen. Nachträglich ist ein unbeabsichtigtes Lösen beim Anpacken des Rahmens nicht zu befürchten, da die Haken hierbei auf die Außenfläche der Stege gedrückt werden. Zum Lösen der Verbindung muß eine von den Außenflächen 23, 25 weggerichtete Kraft ausgeübt werden, um die Haken über die Halteelemente hinwegzuschieben.The holding element 22 visible here, like the other holding element located in front of the plane of the drawing, projects outward beyond the outer surface 23 of the web 8. The tongue 20 is passed between the two holding elements out of the hollow chamber 14 so that the free end of the tongue 20 with the two hooks is above the outer surface 23. The engagement surfaces of the hooks engage behind the holding elements mentioned outside the hollow chamber 14 and above the outer surfaces of the two webs. The two hooks are arranged laterally at the front end of the tongue. When establishing the connection, the hooks first slide over the webs and the holding elements, the free end of the tongue carrying out a movement directed away from the outer surface of the webs. When the hooks have reached the end of the holding elements, a force acting in the direction of the outer surface 23 of the web can act in order to bring the hooks into engagement with the holding elements and thus fix the connection. If, due to the manufacturing tolerance, the hooks do not engage automatically, you can easily press the outside of the hook with your finger to establish the connection. Subsequent unintentional loosening when gripping the frame is not to be feared, since the hooks are pressed onto the outer surface of the webs. To release the connection, a force directed away from the outer surfaces 23, 25 must be exerted in order to push the hooks over the holding elements.

Im rechten Teil der Fig. 2 erkennt man in der Frontalansicht den anderen Zapfen 18 sowie dessen seitliche Haken 26, 28. Auch die Stege 8, 10 der Profilschiene 2 sind zu erkennen. Die Profilschiene 2 weist im Rahmen dieser Erfindung zwei zur Rückseite 34 gerichtete Verlängerungen 36, 38 auf, zwischen welchen sich die Zunge 20 mit den Haken befindet. Die Stege 8, 10 bzw. die Höhe der Verlängerungen 36, 38 sind erfindungsgemäß in der Weise vorgegeben, daß sich die Zunge 20 mit den Haken 26, 28 innerhalb der Profilschiene 2 befindet und nicht über die Rückkante 40 hinausragt.In the right-hand part of FIG. 2, the other pin 18 and its lateral hooks 26, 28 can be seen in the frontal view. The webs 8, 10 of the profile rail 2 can also be seen. Within the scope of this invention, the profile rail 2 has two extensions 36, 38 directed towards the rear 34, between which the tongue 20 with the hooks is located. The webs 8, 10 and the height of the extensions 36, 38 are specified according to the invention in such a way that the tongue 20 with the hooks 26, 28 is located within the profile rail 2 and does not protrude beyond the rear edge 40.

Die Profilschiene 2 weist ferner zur Mitten hin einen L-förmigen Ansatz 42 zur Verankerung des Federelementes 32 auf. Das Federelement 32 hintergreift mit einem Haken 44 den genannten L-Ansatz 42 und verläuft über einen Bogen 46 in ein Fußteil 48 aus. Dieser Fußteil liegt an der Rückseite der Trägerplatte 30 an. Die Trägerplatte 30, ein Bild 50 sowie eine Glasplatte 52 sind in den derart ausgebildeten Rahmen eingesetzt. Hierzu weisen die Profilschienen 2 an der Vorderseite 54 einen Schenkel 56 auf, an dessen Rückseite die Glasplatte 52, wie dargestellt, anliegt. Mittels des Federelements 32 werden die Trägerplatte 30, das Bild 50 sowie die Glasplatte 52 an den Schenkel 56 angedrückt.The profile rail 2 also has an L-shaped extension 42 for anchoring the spring element 32 towards the center. The spring element 32 engages behind the mentioned L-neck 42 with a hook 44 and extends over an arc 46 into a foot part 48. This foot part lies against the back of the carrier plate 30. The carrier plate 30, an image 50 and a glass plate 52 are inserted into the frame formed in this way. For this purpose, the profiled rails 2 have a leg 56 on the front side 54, on the rear side of which the glass plate 52 bears, as shown. The support plate 30, the image 50 and the glass plate 52 are pressed onto the leg 56 by means of the spring element 32.

Der Zusamenbau oder das Auswechseln eines Bildes kann mit wenigen Handgriffen erledigt werden. Hierzu muß lediglich an der einen Seite des Rahmens eine Profilschiene herausgelöst werden. Dies erfolgt erfindungsgemäß in einfacher Weise durch Hochheben der Nase 58 der Zunge 20 mit den Haken 26, 28 über die Halteelemente der Stege hinweg, so daß dann problemlos der jeweilige Zapfen aus der Profilschiene herausgezogen werden kann. Hierzu sind keine Werkzeuge notwendig. Das Zusammensetzen erfolgt in umgekehrter Richtung in der Weise, daß der Zapfen vom Ende her in die Hohlkammer eingeschoben wird. Hierbei gleiten die Haken 26, 28 über die Halteelemente 22, 24 weg und rasten dann hinter die Halteelemente 22, 24 ein.The assembly or replacement of a picture can be done in a few simple steps. To do this, only one side of the Frame a profile rail can be detached. This is done according to the invention in a simple manner by lifting the nose 58 of the tongue 20 with the hooks 26, 28 over the holding elements of the webs, so that the respective pin can then be pulled out of the profile rail without any problems. No tools are required for this. The assembly takes place in the opposite direction in such a way that the pin is inserted into the hollow chamber from the end. Here, the hooks 26, 28 slide away over the holding elements 22, 24 and then snap behind the holding elements 22, 24.

Fig. 3 zeigt eine Aufsicht in Blickrichtung 111 gemäß Fig. 2. Die über die Zapfen 16, 18 jeweils nach vorn verlängerten Zungen 20 mit den seitlichen Haken 26, 28 sind hier gut zu erkennen. Der Eckverbinder bzw. dessen Zapfen 16, 18 enthalten auf der Rückseite Rippen 60 zur Versteifung. Die Rippen 60 ermöglichen ferner einen gewissen Toleranzausgleich. Die Eckverbinder bestehen erfindungsgemäß aus einem Kunststoff, der eine hinreichende Elastizität aufweist. Die Zapfen können mit einem gewissen Übermaß gefertigt werden, wobei die Rippen 60 beim Einschieben in die Hohlkammern sich problemlos etwas zusammendrücken lassen und mit geringem Kraftaufwand das Einschieben ermöglicht wird.FIG. 3 shows a top view in the direction of view 111 according to FIG. 2. The tongues 20 with the side hooks 26, 28, each of which is elongated forward via the pins 16, 18, can be clearly seen here. The corner connector or its pin 16, 18 contain ribs 60 on the back for stiffening. The ribs 60 also allow a certain tolerance compensation. According to the invention, the corner connectors consist of a plastic which has sufficient elasticity. The pins can be manufactured with a certain oversize, the ribs 60 being able to be compressed somewhat easily when inserted into the hollow chambers and the insertion being possible with little effort.

Fig. 4 zeigt eine Ausführungsform, bei welcher die Zunge 20 in Längsrichtung gewellt ausgebildet ist. Die Federwirkung wird hierdurch nicht unwesentlich verbessert, wodurch eine zuverlässige Verbindung gewährleistet werden kann. Fertigungsbedingte Toleranzen, und zwar insbesondere beim Einbringen der Halteelemente 22 in die Stege, können so problemlos ausgeglichen werden, wobei gleichwohl eine funktionsgerechte Verbindung gewährleistet wird. Wesentlich ist ferner auch die Schrägstellung der Eingriffsflächen 62, 64 der Zunge 20 bzw. des Halteelements 22. Durch die derart schräggestellten Eingriffsflächen wird eine Keilwirkung erreicht, aufgrund welcher die Zunge nach dem Hintergreifen des Halteelements 22 zuverlässig in dieser Stellung verankert bleibt. Ein unzulässiges Herauslösen der Haken 26 aus den Halteelementen 22 wird bei geringem Aufwand verhindert.Fig. 4 shows an embodiment in which the tongue 20 is corrugated in the longitudinal direction. The spring action is thereby not insignificantly improved, whereby a reliable connection can be guaranteed. Production-related tolerances, in particular when the holding elements 22 are introduced into the webs, can be compensated for in this way without problems, while a functionally appropriate connection is nevertheless guaranteed. Also important is the inclined position of the engaging surfaces 62, 64 of the tongue 20 or the holding element 22. The engaging surfaces inclined in this way achieve a wedge effect, due to which the tongue remains reliably anchored in this position after reaching behind the holding element 22. Unauthorized removal of the hooks 26 from the holding elements 22 is prevented with little effort.
