Description

Die Erfindung betrifft eine Eckenausbildung , insbesondere für einen Behälterdekkel, beispielsweise für PKW-Nutzanhänger, gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a corner formation, in particular for a container lid, for example for commercial vehicle trailers, according to the preamble of claim 1.

In dem DE-GM 82 13 271 ist ein Behälterdeckel mit Eckenaus-bildungen beschrieben. Dieser Behälterdeckel besteht aus einem Vertikalprofil, das den Deckelrand bildet und mit einem Außenwandflansch auf die Deckplatte übergreift. Weiterhin ist eine die Deckplatte tragende Unterkonstruktion vorhanden, die als Rahmenviereck ausgebildet ist und gegebenenfalls Querstreben aufweist. Diese Unterkonstruktion besteht aus einem Leichtmetall-Hohlprofil und liegt auf einem an der Innenwand des Vertikalprofils ausgebildeten Auflagenbereich auf. Das die Deckplatte bildende Abdeckblech wird zwischen die Unterkonstruktion und den Aussenwandflansch des Vertikalprofils angeordnet und gehalten. Die Befestigung aller Teile erfolgt durch Nieten, Schweißen oder Kleben.DE-GM 82 13 271 describes a container lid with corner formations. This container lid consists of a vertical profile that forms the edge of the lid and overlaps with an outer wall flange on the cover plate. Furthermore, there is a substructure supporting the cover plate, which is designed as a square frame and optionally has cross struts. This substructure consists of a light metal hollow profile and lies on a support area formed on the inner wall of the vertical profile. The cover plate forming the cover plate is arranged and held between the substructure and the outer wall flange of the vertical profile. All parts are fastened by riveting, welding or gluing.

Die Herstellung dieses Behälterdeckels ist wegen der für die Eckbereiche notwendigen Gehrungsschnitte und der nachträglichen Verbindung der Konstruktionsteile arbeits- und damit kostenintensiv.The production of this container lid is labor-intensive and therefore cost-intensive because of the miter cuts required for the corner areas and the subsequent connection of the structural parts.

Bei einer weiterentwickelten, beispielsweise aus Polyamid bestehenden Eckenausbildung werden in diese die durch einen senkrechten Schnitt abgelängten Hohlprofile für den Deckelrand und die die Unterkonstruktion bildenden Hohlprofile eingeschoben und befestigt. Diese Eckenausbildung weist neben mit den Außenwänden des Vertikalprofils fluchtenden, in den Ecken rechtwinklig zusammentreffenden Außenwänden an der Innenseite eine Hohlprofilrahmenecke auf, deren Schenkel über die Außenwände hinausreichen. Die Hohlprofilrahmenecke weist einen rechteckigen Querschnitt auf, so daß die Vertikalprofile mit ihrem Hohlraum formschlüssig aufgeschoben und befestigt werden können. Oberhalb der Hohlprofilrahmenecke und im Bereich der vertikalen Randprofile werden die Hohlprofile der Unterkonstruktion und auf dieser aufliegend die Deckplatte angeordnet, wobei die Außenwandflansche der Vertikalprofile und der Eckenausbildungen über die Deckplatte greifen.In the case of a further developed corner formation, for example made of polyamide, the hollow profiles cut to length by a vertical cut are inserted into the corner The edge of the lid and the hollow profiles forming the substructure are inserted and fastened. This corner formation has, in addition to the outer walls aligned with the outer walls, which meet at right angles in the corners, a hollow profile frame corner on the inside, the legs of which extend beyond the outer walls. The hollow profile frame corner has a rectangular cross section, so that the vertical profiles with their cavity can be positively pushed on and fastened. Above the corner of the hollow profile frame and in the area of the vertical edge profiles, the hollow profiles of the substructure and the cover plate resting thereon are arranged, the outer wall flanges of the vertical profiles and the corner designs reaching over the cover plate.

Durch diese Eckenkonstruktion konnten die Herstellungskosten für Behälterdeckel verringert werden, da die Gehrungsecken für die Rahmenprofile nicht mehr erforderlich sind. Da aber konstruktionsbedingt nach wie vor für die Abdeckfläche eine Unterkonstruktion gefertigt werden muß und alle Konstruktionsteile durch Nieten o.ä. verbunden werden müssen, ist der Herstellungprozeß durch relativ hohe Lohn- und Materialkosten gekennzeichnet.This corner construction made it possible to reduce the manufacturing costs for container lids, since the mitred corners are no longer required for the frame profiles. However, because of the design, a substructure must still be made for the cover surface and all construction parts by rivets or the like. must be connected, the manufacturing process is characterized by relatively high labor and material costs.

In der EP 0 004 459 A2 ist eine Eckenausbildung für eine Wandkonstruktion beschrieben, bei der zwei Flächenelemente zueinander beabstandet und über ein vorgefertigtes, starres Eckprofil und wenigstens ein elastisches Klemmprofil angeordnet und verbunden werden. Das Eckprofil weist eine U-förmige Aufnahme für die Stirnseite des ersten Flächenelementes und außerdem einen mehrfach abgewinkelten Anlagesteg und eine weitere Längsnut auf, zwischen denen das zweite Flächenelement angeordnet wird. Zur Halterung des zweiten Flächenelementes wirkt das elastische Klemmprofil, welches in der Längsnut befestigt wird, mit einer weiteren Dichtung in dem abgewinkelten Anlagesteg zusammen. Bei Verwendung eines kastenförmigen Eckprofilelementes sind zwei abgewinkelte Anlagestege und Längsnute mit Klemmprofilen vorgesehen, wobei zur sicheren Halterung der Flächenelemente das kastenförmige Eckprofil zusätzlich mit zwei horizontal angeordneten, U-förmigen Eckprofilen verbunden wird.EP 0 004 459 A2 describes a corner design for a wall construction in which two surface elements are spaced apart from one another and are arranged and connected via a prefabricated, rigid corner profile and at least one elastic clamping profile. The corner profile has a U-shaped receptacle for the end face of the first surface element and also a multi-angled contact web and a further longitudinal groove, between which the second surface element is arranged. To hold the second surface element, the elastic clamping profile, which is fastened in the longitudinal groove, interacts with a further seal in the angled contact web. When using a box-shaped corner profile element, two angled contact webs and longitudinal grooves with clamping profiles are provided, the box-shaped corner profile being additionally connected to two horizontally arranged, U-shaped corner profiles in order to securely hold the surface elements.

Die Verwendung der vorgefertigten Eckprofile vereinfacht die Montage von Wand- oder Behälterdeckelkonstruktionen, erfordert aber bei der Herstellung eine hohe Maßhaltigkeit und exakte Übereinstimmung der Eckprofilelemente, der Klemmprofile und der Flächenelemente. Elastische Klemmprofile und weitere Dichtungsmassen, die zum Ausgleich der Toleranzen dienen können, unterliegen der Alterung und haben nur eine begrenzte Lebensdauer.The use of the prefabricated corner profiles simplifies the assembly of wall or container lid constructions, but requires a high degree of dimensional accuracy and exact match of the corner profile elements, the clamping profiles and the surface elements. Elastic clamping profiles and other sealing compounds that can be used to compensate for the tolerances are subject to aging and have a limited service life.

Der Erfindung liegt die Aufgabe zugrunde, eine Eckenausbildung zu schaffen, durch die unter Verwendung vorgefertigter Teile die Herstellung beispielsweise von Behälterdeckeln weiter vereinfacht wird, so daß die Kosten für den Produktionsprozeß und auch für die Lagerhaltung, insbesondere die Lohn- und Materialkosten, relativ gering sind.The invention has for its object to provide a corner formation, the production is, for example, is further simplified by reservoir caps through the pre-fabricated using parts, so that the cost for the production process and also for the storage, in particular the labor and material costs, are relatively small .

Bei einer gattungsgemäßen Eckenausbildung wird die Aufgabe erfindungsgemäß durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst. Vorteilhafte und zweckmässige Ausgestaltungen sind in den Unteransprüchen und in dem Ausführungsbeispiel beschrieben.In a generic corner design, the object is achieved according to the invention by the characterizing features of claim 1. Advantageous and practical configurations are described in the subclaims and in the exemplary embodiment.

Grundgedanke der Erfindung ist, ein Flächenelement, insbesondere ein den Deckelrand bildendes Vertikalprofil, so auszubilden, daß ein vorgefertigtes Konstruktionselement, das als Abschnitt, vorzugsweise aber als Schiene, am Vertikalprofil unter Spannung befestigt wird, mit einem Auflager ein zweites Flächenelement, beispielsweise eine relativ leichte und starre Wabenplatte, in einer vorgegebenen Winkellage an den Außenwandflansch des Vertikalprofils festdrückt.The basic idea of the invention is to design a surface element, in particular a vertical profile forming the lid edge, in such a way that a prefabricated construction element which is fastened under tension as a section, but preferably as a rail, to the vertical profile with a support, a second surface element, for example a relatively light one and rigid honeycomb plate, pressed in a predetermined angular position on the outer wall flange of the vertical profile.

Das Konstruktionselement, durch das beispielsweise die Deckplatte eines Behälters mit dem vertikalen Randprofil in einer Klemmhalterung verbunden wird, ist ein Klemmprofil, das zwischen zwei, in einem hinterschnittenen Bereich, beispielsweise in einer Aufnahmetasche, des vertikalen Hohlprofiles ausgebildeten Halterungen so eingeklemmt wird, daß ein zur Deckplatte gerichteter, einseitiger Federflansch das Auflager für die Deckplatte bildet.The structural element, for example, by which the cover plate of a container is connected to the vertical edge profile in a clamping bracket, is a clamping profile which is clamped between two brackets formed in an undercut area, for example in a receiving pocket, of the vertical hollow profile in such a way that one for Cover plate directed, one-sided spring flange forms the support for the cover plate.

Als Federflansch wirkt ein winkelförmig ausgebildeter, oberer Teil des Klemmprofils, dessen Flanschschenkel in der Endlage des Klemmprofils, d.h. wenn die Deckplatte eingeklemmt ist, nicht mehr horizontal, sondern zur Aufnahmetasche geneigt verlaufen.
Das Auflager für die Deckplatte wird vom Schnittpunkt der beiden Federflanschschenkel gebildet. Es ist vorteilhaft, dieses Profil verstärkt auszubilden.
An angled upper part of the clamping profile acts as a spring flange, the flange leg of which no longer runs horizontally in the end position of the clamping profile, ie when the cover plate is clamped, but inclined to the receiving pocket.
The support for the cover plate is formed by the intersection of the two spring flange legs. It is advantageous to develop this profile more intensely.

Die Halterung des Klemmprofils, das nahezu T- oder V-förmig oder als spitzer Winkel ausgebildet ist, wird durch einen in der Aufnahmetasche des Vertikalprofils lagerbaren Lagerfuß und eine am Ende des Flanschschenkels angeordnete Klemmnase, die eine in der Aufnahmetasche ausgeformte Klemmhalterung hintergreift, realisiert.The mounting of the clamping profile, which is almost T-shaped or V-shaped or as an acute angle, is made possible by a bearing foot that can be stored in the receiving pocket of the vertical profile and one at the end of the flange leg arranged clamping lug, which engages behind a formed in the receiving pocket clamp bracket realized.

Vorzugsweise ist die Aufnahmetasche ein partiell oder über die gesamte Länge reichender Hinterschnitt der Innenwand des Vertikalprofils nahe dem Eckbereich.The receiving pocket is preferably an undercut of the inner wall of the vertical profile near the corner area, which underlies part or over the entire length.

Es ist vorteilhaft, wenn die Klemmtasche eine den Lagerfuß des Klemmprofils aufnehmende Rinne aufweist, die komplementär zum gelenkkopfartigen Lagerfuß geformt ist. Die zur Aussenwand geneigte Seitenwand der Aufnahmetasche kann durch einen Quersteg versteift werden. Die Aufnahmetasche weist im oberen Bereich einen nahezu horizontalen Anschlußbereich auf, in dem ein zur Klemmnase formschlüssiger Klemmsteg ausgebildet ist und an den die vertikale Innenwand des Randprofils angrenzt. An diesem Teil der vertikalen Innenwand liegt im eingebauten Zustand die Deckplatte des Behälters an, die zwischen dem Außenwandflansch des Vertikalprofils und dem Auflager des Federflansches des Klemmprofiles festgeklemmt ist. Vorteilhafterweise wird als Deckplatte eine Wabenplatte eingesetzt, die mit Aluminium und/oder Stahl oder einem glasfaserverstärkten Kunststoff beschichtet ist.It is advantageous if the clamping pocket has a groove which receives the bearing base of the clamping profile and is shaped to be complementary to the joint-like bearing base. The side wall of the receiving pocket, which is inclined towards the outer wall, can be stiffened by a crossbar. The receiving pocket has an almost horizontal connection area in the upper region, in which a clamping web which is form-fitting to the clamping lug is formed and to which the vertical inner wall of the edge profile is adjacent. In the installed state, the cover plate of the container lies against this part of the vertical inner wall and is clamped between the outer wall flange of the vertical profile and the support of the spring flange of the clamping profile. A honeycomb plate which is coated with aluminum and / or steel or a glass fiber reinforced plastic is advantageously used as the cover plate.

Es ist zweckmäßig, das Klemmprofil mindestens im Bereich der Klemmhalterung abzudichten, beispielsweise mit einem elastischen Kleber wie Silikon. Um absolute Dichtheit zu erreichen, kann es sinnvoll sein, auch im Bereich des Aussenwandflansches und/oder im Bereich der Lagerrinne und des Lagerfußes ein Dichtungsmaterial einzubringen.It is expedient to seal the clamping profile at least in the area of the clamping bracket, for example with an elastic adhesive such as silicone. In order to achieve absolute tightness, it can make sense to also insert a sealing material in the area of the outer wall flange and / or in the area of the bearing groove and the bearing foot.

Als Werkstoff für das vertikale Hohlprofil und für das Klemmprofil wird vorzugsweise ein mechanisch stabiles Material verwendet, insbesondere Aluminium, da es korrosionsbeständig, leicht und gut verarbeitbar ist. Daneben können auch andere, im Kraftfahrzeugbau übliche Materialien verwendet werden. Die Deckplatte kann auch eine Holzplatte sein. Das Klemmprofil ist vorzugsweise als Alu-Schiene ausgebildet, die über die gesamte Länge des vertikalen Hohlprofils reicht. Neben einer etwa T-förmigen Konfiguration des Klemmprofils, wobei der obere Querschenkel den Federschenkel bildet, können auch andere, strangmäßig herstellbare Querschnittsformen in V-Form oder in Art eines spitzen Winkels verwendet werden. Zur besseren Kraftübertragung vom Klemmbereich mit der Deckplatte in das vertikale Hohlprofil wird eine zumindest geringfügige Schrägstellung des Klemmprofils im eingerasteten Zustand bevorzugt.A mechanically stable material is preferably used as the material for the vertical hollow profile and for the clamping profile Material used, especially aluminum, since it is corrosion-resistant, light and easy to process. In addition, other materials customary in motor vehicle construction can also be used. The cover plate can also be a wooden plate. The clamping profile is preferably designed as an aluminum rail, which extends over the entire length of the vertical hollow profile. In addition to an approximately T-shaped configuration of the clamping profile, the upper cross leg forming the spring leg, other cross-sectional shapes in the shape of a V, or in the manner of an acute angle, can also be used. For better power transmission from the clamping area with the cover plate into the vertical hollow profile, an at least slight inclination of the clamping profile in the locked state is preferred.

Bei der Herstellung eines Behälterdeckels kann daher dieses Klemmprofil über alle vier Längsseiten eingesetzt werden. Für die Eckbereiche der vertikalen Hohlprofile bedarf es keiner Gehrungsschnitte mehr, da dort z.B. Kunststoff-Dekkelecken eingesetzt werden können, die außenflächig fluchtend mit den Außenflächen der vertikalen Hohlprofile abschließen können oder auch diese geringfügig überlappen können. Hierbei ist es möglich, daß ein über eine Längsseite angeordnetes Klemmprofil unterteilt ist, so daß ein innerer Eingriff in die Kunststoff-Deckelecke möglich ist. Bei Einsatz derartiger Kunststoff-Deckelecken wird üblicherweise eine Abdichtung, z.B. mittels Silikon, gegenüber den verwendeten Strangprofilen vorgesehen.When producing a container lid, this clamping profile can therefore be used on all four long sides. Miter cuts are no longer required for the corner areas of the vertical hollow profiles, as there e.g. Plastic corner corners can be used, the outer surface flush with the outer surfaces of the vertical hollow profiles or can overlap them slightly. It is possible that a clamping profile arranged over a longitudinal side is divided so that an internal engagement in the plastic cover corner is possible. When using such plastic lid corners, a seal, e.g. by means of silicone, compared to the extruded profiles used.

Da bei der erfindungsgemäßen Eckenkonstruktion wenige vorgefertigte Teile verwendet werden, bei denen das zeitaufwendige Befestigen durch Vernieten oder Schweißen nicht erforderlich ist, können die Kosten für das Herstellen von Behältern oder Behälterdeckeln erheblich gesenkt werden.Since few prefabricated parts are used in the corner construction according to the invention, in which the time-consuming fastening by riveting or welding is not necessary, the costs for the production of containers or container lids can be considerably reduced.

Die erfindungsgemäße Eckenausbildung erlaubt ein einfaches Verbinden von Flächenelementen und ermöglicht, beispielsweise bei Beschädigung eines Elementes, auch die Demontage und Wiederverwendung des Klemmprofiles und/oder eines Flächenelementes.The corner design according to the invention allows simple connection of surface elements and also enables, for example in the event of damage to an element, the dismantling and reuse of the clamping profile and / or a surface element.

Die Erfindung wird nachstehend beispielsweise anhand der schematischen Zeichnung beschrieben. Die zugehörige Zeichnung zeigt in

The invention is described below, for example, using the schematic drawing. The associated drawing shows in
Fig. 1
is a schematic, vertical sectional view of the corner formation according to the invention.

Zur Herstellung eines Behälterdeckels, beispielsweise für einen PKW-Anhänger, werden zwei Flächenelemente 1, 7 zu einer Eckenausbildung verbunden. Das erste Flächenelement 1 ist ein vertikales Hohlprofil 2, beispielsweise aus Aluminium, das eine Innenwand 3 und eine Außenwand 4 mit einem auf das zweite Flächenelement 7, beispielsweise eine Deckplatte 7, übergreifenden Außenwandflansch 5 aufweist. Als Deckplatte 7 wird eine starre, relativ leichte Wabenplatte, die beschichtet sein kann, verwendet. Sowohl die Deckplatte 7 als auch die den Deckelrand bildenden Vertikalprofile 2 weisen die für den Behälterdeckel erforderlichen Abmessungen auf. Auch das dritte Konstruktionselement, ein als vorgefertigte Aluminiumschiene ausgebildetes Klemmprofil 10, ist auf das erforderliche Maß abgelängt.To produce a container lid, for example for a car trailer, two surface elements 1, 7 are connected to form a corner. The first surface element 1 is a vertical hollow profile 2, for example made of aluminum, which has an inner wall 3 and an outer wall 4 with an outer wall flange 5 which overlaps the second surface element 7, for example a cover plate 7. A rigid, relatively light honeycomb plate, which can be coated, is used as the cover plate 7. Both the cover plate 7 and the vertical profiles 2 forming the cover edge have the dimensions required for the container cover. The third structural element, a clamping profile 10 designed as a prefabricated aluminum rail, is also cut to the required size.

Das nahezu T-förmige Klemmprofil 10 besteht aus einem in der Endlage mit der Innenwand 3 des Vertikalprofils 2 fluchtenden Steg 12 mit endseitigen Halterungen 11, 13 oder Endlagern, nämlich an seinem unteren Ende einen Lagerfuß 14 als endseitige Halterung 11 und an seinem oberen Ende eine Ausformung 18, beispielsweise eine Klemmnase 18, für eine Klemmhalterung als obere endseitige Halterung 13.The almost T-shaped clamping profile 10 consists of a web 12 in the end position aligned with the inner wall 3 of the vertical profile 2 with end brackets 11, 13 or end bearings, namely at its lower end a bearing base 14 as end bracket 11 and at its upper end one Forming 18, for example a clamping lug 18, for a clamping bracket as the upper end bracket 13.

Dieses Klemmprofil 10 ist mit seinen etwa übereinander angeordneten Endlagern oder endseitigen Halterungen 11, 13, nämlich dem Lagerfuß 14 und der Klemmnase 18, in die Aufnahmetasche 20 einsteckbar bzw. einrastbar ausgebildet. Ein einseitiger Federflansch 16, der vom Steg 12 ausgehend spitzwinklig ausgebildet ist, weist mit einem Schnittpunkt der zwei Flanschschenkel zur Deckplatte 7, während am gegenüberliegenden Ende des nahezu horizontalen oberen Schenkels des Federflansches 16 die Klemmnase 18 in die Aufnahmetasche 20 gerichtet ist. Der Lagerfuß 14 des Klemmprofils 10 ist gelenkkopfartig ausgebildet und lagert lösbar in der komplementär geformten Rinne 24 der Aufnahmetasche 20. Oberhalb des Lagerfußes 14 geht das Klemmprofil 10 stufenförmig in den mit der Innenwand 3 fluchtenden Steg 12 über. Dadurch wird die beim Einlegen der Deckplatte 7 erforderliche Kippstellung des Klemmprofils 10, die durch die gestrichelten Linien wiedergegeben ist, ermöglicht. Gleichzeitig ist am Übergang der Innenwand 3 zum Klemmprofil 10 eine nahezu geschlossene Fläche gegeben. Das Auflager 17 für die Deckplatte 7 ist im Schnittpunktbereich der zwei Flanschschenkel des Federflansches 16 gebildet. Es ist profilverstärkt ausgebildet, um eine sichere Klemmhalterung der Deckplatte 7 zwischen dem Auflager 17 und dem Außenwandflansch 5 zu gewährleisten.This clamping profile 10, with its approximately superimposed end bearings or end supports 11, 13, namely the bearing foot 14 and the clamping lug 18, can be inserted or latched into the receiving pocket 20. A one-sided spring flange 16, which is formed at an acute angle from the web 12, points at an intersection of the two flange legs to the cover plate 7, while at the opposite end of the almost horizontal upper leg of the spring flange 16, the clamping lug 18 is directed into the receiving pocket 20. The bearing base 14 of the clamping profile 10 is designed in the manner of a joint head and is detachably supported in the complementarily shaped groove 24 of the receiving pocket 20. Above the bearing base 14, the clamping profile 10 merges step-wise into the web 12 aligned with the inner wall 3. This enables the tilting position of the clamping profile 10 required when inserting the cover plate 7, which is represented by the dashed lines. At the same time, an almost closed surface is provided at the transition from the inner wall 3 to the clamping profile 10. The support 17 for the cover plate 7 is formed in the intersection area of the two flange legs of the spring flange 16. It has a profile-reinforced design in order to ensure that the cover plate 7 is securely clamped between the support 17 and the outer wall flange 5.

Die Aufnahmetasche 20 ist in diesem Ausführungsbeispiel als linienförmige Einbauchung bzw. als Hinterschnitt in der Innenwand 3 des Vertikalprofils 2 nahe dem Eckbereich ausgebildet. Sie besteht aus einer den Lagerfuß 14 des Klemmprofils 10 aufnehmenden Rinne 24, einer in Richtung Außenwand 4 des Vertikalprofils 2 geneigten Seitenwand 22 und einem nahezu horizontalen Anschlußbereich 26 zu der Innenwand 3, die vertikal ausgerichtet ist und die Deckplatte 7 begrenzt. Die Aufnahmetasche 20 ist im Bereich der geneigten Seitenwand 22 durch einen Quersteg 30 zur Außenwand 4 versteift ausgebildet. Die Klemmhalterung des Klemmprofils 10 wird mit Hilfe der Rinne 24 und eines Klemmstegs 28, der im nahezu horizontalen Teil des Anschlußbereiches 26 ausgebildet ist, erreicht. Dieser Klemmsteg 28 ist formschlüssig zur Klemmnase 18 des Klemmprofils 10 ausgebildet, so daß in der Endlage die Klemmnase 18 diesen Klemmsteg 28 kraftschlüssig hintergreift.In this exemplary embodiment, the receiving pocket 20 is designed as a linear indentation or as an undercut in the inner wall 3 of the vertical profile 2 near the corner region. It consists of a channel 24 receiving the bearing base 14 of the clamping profile 10, a side wall 22 inclined in the direction of the outer wall 4 of the vertical profile 2 and an almost horizontal connecting region 26 to the inner wall 3, which is oriented vertically and delimits the cover plate 7. The receiving pocket 20 is stiffened in the region of the inclined side wall 22 by a crossbar 30 to the outer wall 4. The clamping bracket of the clamping profile 10 is by means of the groove 24 and a clamping web 28, the is formed in the almost horizontal part of the connection region 26 is reached. This clamping web 28 is form-fitting to the clamping lug 18 of the clamping profile 10, so that in the end position the clamping lug 18 engages behind this clamping web 28 in a non-positive manner.

Zum Verbinden der Deckplatte 7 mit dem Vertikalprofil 2 wird das Klemmprofil 10 mit dem Lagerfuß 14 in die Rinne 24 der Aufnahmetasche 20 eingeschoben. Indem der untere Klemmprofilsteg 12 auf der Innenwand 3 aufliegt, befindet sich der einseitige Federflansch 16 nahezu horizontal zum Außenwandflansch 5 des Vertikalprofils 2. Die Deckplatte 7 kann nunmehr auf das Auflager 17 aufgelegt und bis an die obere Innenwand 3 des Vertikalprofils 2 eingeschoben werden. Durch Druckausübung auf den vertikalen Steg 12 des Klemmprofils 10 wird das gesamte Klemmprofil 10 in Richtung Außenwand 4 und somit in Klemmlagerung gedrückt. Dabei rastet die Klemmnase 18 hinter den Klemmsteg 28 der Aufnahmetasche 20 ein, wobei gleichzeitig das Auflager 17 gegen die Deckplatte 7 gedrückt und diese dadurch gegen den Außenwandflansch 5 festgelegt wird.To connect the cover plate 7 to the vertical profile 2, the clamping profile 10 is inserted with the bearing foot 14 into the groove 24 of the receiving pocket 20. Since the lower clamping profile web 12 rests on the inner wall 3, the one-sided spring flange 16 is located almost horizontally to the outer wall flange 5 of the vertical profile 2. The cover plate 7 can now be placed on the support 17 and pushed up to the upper inner wall 3 of the vertical profile 2. By exerting pressure on the vertical web 12 of the clamping profile 10, the entire clamping profile 10 is pressed in the direction of the outer wall 4 and thus in the clamping bearing. The clamping lug 18 snaps behind the clamping web 28 of the receiving pocket 20, the bearing 17 being pressed against the cover plate 7 at the same time, and this is thereby fixed against the outer wall flange 5.

Es ist möglich, vor dem Verklemmen des Profils in dem Bereich der Klemmnase 18 und des Klemmsteges 28 ein Dichtungsmaterial, z.B. Silikon, einzuspritzen, um die Dichtheit des Behälters bzw. des Behälterdeckels zu gewährleisten. Da die erfindungsgemäße Eckenausbildung eine sichere und dichte Verbindung zweier Flächenelemente, insbesondere einer Deckplatte mit einer vertikalen Wand, realisiert, entfallen die bisher benötigte Unterkonstruktion sowie das bisher übliche, nachträgliche Verbinden der Konstruktionsteile, beispielsweise durch Vernieten oder Verschweissen oder durch ein zusätzliches Verbindungselement, z.B. Eckprofil, so daß die Herstellung von Eckenverbindungen wesentlich einfacher und mit relativ geringen Kosten verbunden ist.Before the profile is clamped in the area of the clamping lug 18 and the clamping web 28, it is possible to use a sealing material, e.g. Inject silicone to ensure the tightness of the container or the container lid. Since the corner formation according to the invention realizes a secure and tight connection of two surface elements, in particular a cover plate with a vertical wall, the previously required substructure as well as the previously common, subsequent connection of the structural parts, for example by riveting or welding or by an additional connecting element, e.g. Corner profile, so that the manufacture of corner connections is much easier and at relatively low cost.
