Description

Die Erfindung betrifft eine Abdeckung für eine Entwässerungseinrichtung, insbesondere eine Entwässerungsrinne, mit einem Rinnenkörper, der auf einem Oberrand des Rinnenkörpers aufsetzbaren Abdeckung, welche in den Rinnenkörper ragende Arretierungsstege aufweist und mit wenigstens einem Befestigungselement zum Befestigen der Abdeckung auf dem Rinnenkörper, oder auf einer auf dem Rinnenkörper zur Verstärkung des Oberrandes liegenden Zarge, nach dem Oberbegriff des Anspruchs 1.The invention relates to a cover for a drainage device, in particular a drainage channel, with a channel body, which can be placed on an upper edge of the channel body cover, which has in the gutter body projecting Arretierungsstege and at least one fastening element for securing the cover on the gutter body, or on a on the gutter body to reinforce the upper edge lying frame, according to the preamble of claim 1.

Entwässerungsanordnungen, insbesondere Entwässerungsrinnen oder dergleichen, bei denen die Abdeckung auf dem Rinnenkörper mit Hilfe von Befestigungselementen befestigbar ist, sind bekannt.Drainage arrangements, in particular drainage channels or the like, in which the cover can be fastened on the channel body by means of fastening elements, are known.

Aus der DE 195 04 869 C1 ist eine Entwässerungsrinne mit an einem Rinnenkörper befestigbaren Abdeckrost bekannt. Die Verriegelung des Abdeckrostes wird mittels einer blattförmigen Abdeckrost-Verriegelungsfeder erzielt, welche gegenüberliegend ausgebildete Auskragungen aufweist, die in Aussparungen der Seitenwände des Rinnenkörpers eingreifen. Nach dem Eingreifen oder Einrasten der Auskragungen nimmt die Abdeckrost-Verriegelungsfeder eine im wesentlichen spannungsfreie Lage im Inneren des Rinnenkörpers ein. Durch am Abdeckrost angebrachte Arretierungsbügel mit abgewinkelten Schenkeln wird beim Einsetzen des Abdeckrostes in den Rinnenkörper unter Überwindung der Federkraft die Verriegelung des Abdeckrostes erreicht.From the DE 195 04 869 C1 is a drainage channel with attachable to a gutter body cover grate known. The locking of the cover grating is achieved by means of a leaf-shaped covering grate-locking spring, which has oppositely formed projections which engage in recesses of the side walls of the channel body. After the engagement or engagement of the projections, the cover grate locking spring assumes a substantially stress-free position in the interior of the channel body. By attached to the cover grate locking bracket with angled legs is achieved when inserting the cover grate in the gutter body overcoming the spring force locking the Abdeckrostes.

Diese bekannte Entwässerungseinrichtung mit einer Abdeckrost-Verriegelungsfeder weist den Nachteil auf, daß die Verriegelungsfeder im Inneren des Rinnenkörpers angeordnet ist, und zwar quer zur Längsachse. Somit ist der Rinnenquerschnitt nicht frei, was zu Verstopfungen führen kann, bzw. die Säuberungsarbeiten wesentlich erschwert. Ein weiterer Nachteil besteht darin, daß die Wände des Rinnenkörpers Aussparungen - aufweisen, die zum Eingreifen der Verriegelungsfeder dienen. Die Aussparungen sind im wesentlichen auf halber Höhe des Rinnenkörpers angeordnet. Somit sind die Stabilität und die Lebensdauer des Rinnenkörpers angesichts der hohen Oberflächen-Belastungen beeinträchtigt.This known dewatering device with a cover grate-locking spring has the disadvantage that the locking spring is arranged in the interior of the channel body, and that transverse to the longitudinal axis. Thus, the channel cross-section is not free, which can lead to blockages, or makes the cleaning much more difficult. Another disadvantage is that the walls of the gutter body recesses - have, which serve to engage the locking spring. The recesses are arranged substantially at half the height of the channel body. Thus, the stability and the life of the gutter body are compromised in view of the high surface loads.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Abdeckung für eine Entwässerungseinrichtung mit einer Befestigungsanordnung der eingangs genannten Art dahingehend weiterzubilden, daß einerseits eine haltbare Befestigung der Abdeckung auf dem Rinnenkörper bei einer einfachen Herstellung und Montage der Befestigungsanordnung gewährleistet und andererseits ein freier Rinnenquerschnitt ermöglicht wird.The invention is therefore the object of developing a cover for a dewatering device with a mounting arrangement of the type mentioned in that on the one hand ensures a durable attachment of the cover on the gutter body with a simple manufacture and assembly of the mounting arrangement and on the other hand, a free channel cross section is made possible.

Diese Aufgabe wird durch eine Abdeckung gemäß Patentanspruch 1 gelöst.This object is achieved by a cover according to claim 1.

Ein grundlegender Gedanke der Erfindung liegt darin, daß das Befestigungselement durch die Ausnehmung geführt wird. Die Stabilität der Befestigung hängt somit nicht allein vom Befestigungselement und dessen Stabilität ab. Die Verbindung ist dabei eine Rastverbindung.A basic idea of the invention is that the fastener is passed through the recess. The stability of the attachment thus does not depend solely on the fastener and its stability. The connection is a locking connection.

Da die Verriegelung im oberen Bereich des Rinnenkörpers erfolgt, ist nach dem Aufsetzen der Abdeckung auf dem Rinnenkörper ein freier Rinnenquerschnitt vorhanden. Dadurch wird eine optimierte hydraulische Leistungsfähigkeit gewährleistet. Zudem ist das Befestigungselement als Verriegelungsfeder ausgebildet. Das Befestigungselement weist einen mittleren Abschnitt auf, an dessen Enden Auskragungen vorgesehen sind, durch die die Verriegelung der Abdeckung mit dem Rinnenkörper erfolgt. Dabei ragen die Auskragungen aus den Ausnehmungen in den Arretierungsstegen heraus. Der mittlere Abschnitt erstreckt sich unmittelbar unterhalb der Abdeckung und ist vorzugsweise an einer Unterfläche der Abdeckung befestigbar. Somit werden ein besserer Halt des Befestigungselements gewährleistet, sowie die Sicherheit der Verriegelung erhöht.Since the locking takes place in the upper region of the channel body, a free channel cross-section is present after placing the cover on the channel body. This ensures optimized hydraulic performance. In addition, the fastening element is designed as a locking spring. The fastening element has a central portion, at the ends of which projections are provided, through which the locking of the cover with the channel body takes place. The protrusions protrude from the recesses in the Arretierungsstegen out. The central portion extends immediately below the cover and is preferably attachable to a lower surface of the cover. Thus, a better grip of the fastener are ensured, and increases the security of the lock.

Vorzugsweise weist die Ausnehmung einen Unterrand auf, so daß das Befestigungselement zwischen diesem Unterrand und einer Arretierungsfläche der Aussparung im Verriegelungszustand steckt. Das Befestigungselement kann dann sehr einfach und leicht ausgebildet sein, da es wie ein in eine Schlossfalle geschnappter Türriegel wirkt.Preferably, the recess has a lower edge, so that the fastening element between this lower edge and a locking surface of the recess is in the locked state. The fastener can then be very simple and lightweight, since it acts like a snapped into a lock latch door latch.

Falls eine Zarge zur Verstärkung des Oberrandes des Rinnenkörpers vorgesehen ist, greift das Befestigungselement, welches aus den Ausnehmungen herausragt, unterhalb der Zarge in die Aussparungen der Körperwände ein, wobei die Zarge als Halteelement für die Verriegelung dient. Somit erfolgt die Verriegelung im oberen Bereich des Rinnenkörpers unmittelbar unterhalb der Abdeckung.If a frame is provided for reinforcing the upper edge of the gutter body, the fastening element, which protrudes from the recesses engages below the frame in the recesses of the body walls, wherein the frame serves as a holding element for the locking. Thus, the locking takes place in the upper region of the channel body immediately below the cover.

Bevorzugt sind die Auskragungen des Befestigungselements, welche zur Bildung von gegen die Horizontale geneigten Schrägflächen dienen, spiegelsymmetrisch und sich konisch verjüngend ausgebildet. Die Auskragungen weisen dabei einen ersten und einen zweiten abgewinkelten Abschnitte auf. Der zweite abgewinkelte Abschnitt ist nasenförmig ausgebildet und greift in die Ausnehmung des Arretierungssteges ein, um das Befestigungselement mit der Abdeckung zu verbinden. Die freien Enden des Befestigungselements erstrecken sich dabei in Richtung des Rinneninneren. Bei der Befestigung des Befestigungselements mit der Abdeckung ragen die Haltenasen aus den Ausnehmungen der Arretierungsstege heraus. Dabei kann das Befestigungselement relativ leicht in die Abdeckung eingesteckt werden. Somit kann die Abdeckung auf den Rinnenkörper aufgesetzt und befestigt werden, wobei die Haltenasen in den Aussparungen der Rinnenwände einrasten.Preferably, the projections of the fastener, which are inclined to form against the horizontal Be used oblique surfaces, mirror-symmetrical and conically tapered. The projections have a first and a second angled portions. The second angled portion is nose-shaped and engages in the recess of the Arretierungssteges to connect the fastener with the cover. The free ends of the fastener extend in the direction of the channel interior. When mounting the fastener with the cover, the retaining lugs protrude from the recesses of the locking webs. In this case, the fastening element can be inserted relatively easily into the cover. Thus, the cover can be placed and fixed on the gutter body, wherein the retaining lugs engage in the recesses of the gutter walls.

Bevorzugt ist die Zarge in Richtung des Rinnenbodens abgewinkelt und bildet eine Arretierungsfläche zum Eingriff mit dem Befestigungselement. Der abgewinkelte Zargenabschnitt und die ebenfalls nach unten in Richtung des Rinnenbodens ragende Arretierungsstege verlaufen im aufgesetzten Zustand der Abdeckung auf dem Rinnenkörper nebeneinander.Preferably, the frame is angled in the direction of the channel bottom and forms a locking surface for engagement with the fastening element. The angled frame portion and also projecting downwards in the direction of the gutter bottom Arretierungsstege run in the attached state of the cover on the gutter body side by side.

Die Befestigungseelemente sind vorzugsweise derart ausgebildet, daß beim Aufsetzen der Abdeckung auf den Rinnenkörper die aus den Ausnehmungen der Abdeckung ragende Haltenasen der Befestigungselemente an dem Rinnenkörper oder der Zarge entlang gleiten. Dabei sind die Befestigungselemente unter Ausübung einer Druckkraft in Richtung des Rinneninneren elastisch verformbar. In einer endgültigen Auflageposition der Abdeckung auf dem Rinnenkörper schnappen die Haltenasen in die Aussparungen ein. Durch diese Rastverbindung wird einerseits eine haltbare Verriegelung der Abdeckung erzielt und andererseits - eine ausreichende Sicherheit gegen unerwünschtes Abheben der Abdeckung gewährleistet.The Befestigungsseelemente are preferably formed such that when placing the cover on the gutter body which project from the recesses of the cover retaining lugs of the fasteners on the gutter body or the frame along slide. The fastening elements are elastically deformable by exerting a compressive force in the direction of the channel interior. In a final support position of the cover on the gutter body, the retaining lugs snap into the recesses. By this locking connection on the one hand a durable locking of the cover is achieved and on the other hand - ensures sufficient security against unwanted lifting the cover.

Vorzugsweise ist die Abdeckung durch das Befestigungselement im verriegelten Zustand der Abdeckung auf den Körper oder auf die Zarge gespannt. Die Abdeckung wird somit spielfrei im Rinnenkörper fixiert.Preferably, the cover is stretched by the fastener in the locked state of the cover on the body or on the frame. The cover is thus fixed backlash in the gutter body.

Bevorzugt ist das Befestigungselement derart ausgebildet, daß die zur Verformung des Befestigungselements nötige Kraft niedriger als die zum Lösen der Arretierung und zum Abheben der Abdeckung nötige Kraft ist. Somit wird die Abdeckung sicher auf dem Rinnenkörper angebracht und nur bei notwendigen Reparatur- oder Reinigungsarbeiten abgenommen.Preferably, the fastening element is designed such that the force necessary for the deformation of the fastening element is lower than the force required to release the locking and to lift off the cover. Thus, the cover is securely mounted on the gutter body and removed only when necessary repair or cleaning work.

Vorzugsweise sind die Aussparungen in den Rinnenwänden, in welchen die Haltenasen des Befestigungselements in Verriegelungsposition angebracht werden im Außenflächenbereich geschlossen ausgeführt. Somit werden einerseits Verschmutzungen vermieden und andererseits wird die mechanische Stabilität des Rinnenkörpers, welcher mit hohen Lasten beansprucht wird, erhöht.Preferably, the recesses in the gutter walls, in which the retaining lugs of the fastening element are mounted in the locked position, are designed to be closed in the outer surface area. Thus, on the one hand dirt is avoided and on the other hand, the mechanical stability of the gutter body, which is claimed with high loads, increased.

Die Breite des Befestigungselements entspricht vorzugsweise im wesentlichen der Breite der Aussparungen in den Rinnenwänden. Somit kann neben der Verriegelung auch eine zusätzliche horizontale Verschiebesicherung der Abdeckung gegenüber dem Rinnenkörper erreicht werden. Daher erübrigen sich zusätzliche Verschiebesicherungs-Vorrichtungen.The width of the fastener preferably corresponds substantially to the width of the recesses in the gutter walls. Thus, in addition to the lock, an additional horizontal displacement protection of the cover against the gutter body can be achieved. Therefore, additional anti-slip devices are unnecessary.

Das Befestigungselement kann vorzugsweise einstückig ausgebildet werden, wobei eine teilweise einstückige Ausführung ebenfalls möglich ist. Das Befestigungselement kann sowohl aus Metall, als auch als Kunststoffteil, insbesondere als Spritzgußteil ausgebildet werden.The fastening element may preferably be formed in one piece, wherein a partially integral design is also possible. The fastening element can be formed both from metal, as well as a plastic part, in particular as an injection molded part.

Die Abdeckung kann sowohl aus Stahlblech, Edelstahlblech oder Eisenguß als auch aus Kunststoff geformt werden.The cover can be formed from sheet steel, stainless steel or cast iron as well as plastic.

Die Abdeckung wird vorzugsweise als Stegrost ausgebildet. Dabei kann das Befestigungselement derart dimensioniert werden, daß der mittlere Abschnitt des Befestigungselements unter einem Steg des Stegrostes angeordnet werden kann. Somit ist das Befestigungselement von der Oberfläche her unzugänglich und eine Vandalensicherung gewährleistet.The cover is preferably formed as a web grid. In this case, the fastening element can be dimensioned such that the central portion of the fastening element can be arranged below a web of the grid. Thus, the fastener from the surface is inaccessible and a Vandalensicherung guaranteed.

Diese werden anhand von Abbildungen näher erläutert.Further preferred embodiments of the invention will become apparent from the dependent claims and the following description of preferred embodiments.

Figur 1 zeigt einen Querschnitt durch eine Entwässerungsrinne mit einer Verriegelungsfeder 30. Die Entwässerungsrinne weist einen in den Boden einbaubaren Rinnenkörper 10 und eine auf dem Rinnenkörper 10 aufsetzbaren Abdeckung 20 auf. Die Verriegelungsfeder 30 wird zum Befestigen der Abdeckung 20 auf den Rinnenkörper 10 verwendet.1 shows a cross section through a drainage channel with a locking spring 30. The drainage channel has a gutter body 10 which can be installed in the ground and a cover 20 which can be placed on the gutter body 10. The locking spring 30 is used for attaching the cover 20 to the gutter body 10.

Der Rinnenkörper 10 ist im wesentlichen V-förmig ausgebildet, wobei eine andere Ausbildung, beispielsweise U-förmige, ebenfalls möglich ist. Der Rinnenkörper 10 ist aus Polymerbeton gefertigt und besteht aus einem unteren Körper mit Seitenwänden 11 sowie aus einer Zarge 14. Die Zarge 14 dient einerseits zur Verstärkung des Oberrandes 12 der Rinnenwände 11 und zur Auflage der Abdeckung 20 und andererseits als ein Halteelement für die Verriegelung der Abdeckung 20. Die Zarge 14 ist aus Metall ausgebildet.The gutter body 10 is formed substantially V-shaped, with another design, such as U-shaped, is also possible. The channel body 10 is made of polymer concrete and consists of a lower body with side walls 11 and a frame 14. The frame 14 serves on the one hand to reinforce the upper edge 12 of the channel walls 11 and the support of the cover 20 and on the other hand as a holding element for locking the Cover 20. The frame 14 is formed of metal.

Die Abdeckung 20 ist als Stegrost aus Blech gebogen, wobei eine andere Ausführung beispielsweise als Maschenrost ebenfalls möglich ist. Die Abdeckung 20 weist für die jeweiligen Längsränder eine gebogene Doppelfläche 24 auf. Die Doppelfläche 24 geht integral in Arretierungsstege 21 über, welche nach unten in Richtung des Rinnenbodens gebogen sind. Die nach unten gebogene Arretierungsstege 21 weisen nach oben in Oberflächenrichtung durch Ausstanzungen kippenden Enden 26 auf. Die Enden 26 der Arretierungsstege 21 dienen als eine Abstützung der Abdeckung 20, und zwar in dem Bereich, welcher am weitesten ihnen liegt. Dadurch wird die Biegefestigkeit der Abdeckung 20 erheblich erhöht.The cover 20 is bent as web ridge from sheet metal, wherein another embodiment, for example, as a mesh grid is also possible. The cover 20 has a curved double surface 24 for the respective longitudinal edges. The double surface 24 merges integrally into locking webs 21, which are bent downwards in the direction of the channel bottom. The bent down locking webs 21 have upwardly in the surface direction by punching tipping ends 26. The ends 26 of the locking webs 21 serve as a support of the cover 20, in the region which is farthest to them. As a result, the bending strength of the cover 20 is considerably increased.

Beim Aufsetzen der Abdeckung 20 auf den Rinnenkörper 10 liegt die Doppelfläche 24 auf der Zarge 14. Die Zarge 14 ist in Richtung des Rinneninneren abgewinkelt. Die Zarge 14 weist darüber hinaus einen Vorsprung 16 auf, welcher derart dimensioniert ist, daß seine Höhe die Höhe der Doppelfläche 24 entspricht und somit die Ränder der Abdeckung 20 in Rinnenlängsrichtung von der Zarge 14 umfasst sind.When placing the cover 20 on the gutter body 10 is the double surface 24 on the frame 14. The frame 14 is angled in the direction of the channel interior. The frame 14 also has a projection 16 which is dimensioned such that its height corresponds to the height of the double surface 24 and thus the edges of the cover 20 are included in the gutter longitudinal direction of the frame 14.

Beim Aufsetzen der Abdeckung 20 auf dem Rinnenkörper 10 überdecken die Arretierungsstege 21 die Aussparungen 13, welche in den Rinnenwänden 11 für die Verriegelung vorgesehen sind. Die Arretierungsstege 21 sind dabei mit Ausnehmungen 22 versehen. Die Ausnehmungen 22 korrespondieren mit den Aussparungen 13 bzw. 17 in den Rinnenwänden 11 bzw. Zargen 14. Die Ausnehmungen 22 sind derart dimensioniert, daß die Verriegelungsfeder 30 in die Ausnehmungen 22 geführt wird.When placing the cover 20 on the channel body 10, the locking webs 21 cover the recesses 13, which are provided in the channel walls 11 for locking. The locking webs 21 are provided with recesses 22. The recesses 22 correspond to the recesses 13 and 17 in the channel walls 11 and frames 14. The recesses 22 are dimensioned such that the locking spring 30 is guided in the recesses 22.

Die Aussparungen 13 in den Rinnenwänden 11 sind derart ausgebildet, daß sie durch einen abgewinkelten Zargenabschnitt 15 teilweise überdeckt sind. Der Zargenabschnitt 15 weist dabei eine Arretierungsfläche 17 auf. Somit dient die Zarge 14 nicht nur zum Schutz der Oberränder 12 der Rinnenwände 11, sondern auch als Arretierungsmittel.The recesses 13 in the channel walls 11 are formed such that they are partially covered by an angled frame portion 15. The frame portion 15 in this case has a locking surface 17. Thus, the frame 14 serves not only to protect the upper edges 12 of the channel walls 11, but also as a locking means.

Die Ausnehmungen 22 weisen einen Unterrand 36 auf. Der Unterrand 36 ist derart ausgebildet, daß im Verriegelungszustand das Befestigungselement 30 zwischen dem Unterrand 36 und der Arretierungsfläche 17 der Aussparung steckt und beim Abheben der Abdeckung 20 mit einer Scherkraft beaufschlagt wird.The recesses 22 have a lower edge 36. The lower edge 36 is formed such that in the locked state, the fastener 30 between the lower edge 36 and the locking surface 17 of the recess inserted and is acted upon lifting the cover 20 with a shearing force.

Die Verriegelungsfeder 30 ist blattförmig ausgebildet und weist, wie auch aus Figur 2 ersichtlich, einen mittleren Abschnitt 31 sowie zwei spiegelsymmetrisch ausgebildete Auskragungen 32 auf. Die Auskragungen 32 sind sich konisch verjüngend ausgebildet und weisen einen ersten gebogenen Abschnitt 33 und einen zweiten gebogenen Abschnitt 34 auf. Der zweite Abschnitt 34 ist nasenförmig ausgebildet und dient zur Befestigung der Verriegelungsfeder 30 einerseits mit der Abdeckung 20 und andererseits zur Befestigung der Abdeckung 20 mit eingestecker Verriegelungsfeder 30 auf dem Rinnenkörper 10. Die freien Enden 35 der Verriegelungsfeder 30 ragen in Richtung des Rinneninneren.The locking spring 30 is formed leaf-shaped and has, as also seen in Figure 2, a central portion 31 and two mirror-symmetrical projections 32. The projections 32 are conically tapered and have a first bent portion 33 and a second bent portion 34. The second portion 34 is formed nose-shaped and serves for fastening the locking spring 30 on the one hand with the cover 20 and on the other hand for fastening the cover 20 with inserted locking spring 30 on the channel body 10. The free ends 35 of the locking spring 30 protrude in the direction of the channel interior.

Figur 3 zeigt eine perspektivische Darstellung der Abdeckung 20 mit eingesteckter Verriegelungsfeder 30. Die Ausnehmungen 22 in den Arretierungsstegen 21 sind derart angeordnet, daß die eingesteckte Verriegelungsfeder 30 mit ihren mittleren Abschnitt 31 auf der Unterseite eines Steges 25 angebracht ist. Aus dieser Darstellung ist ersichtlich, daß der mittlere Abschnitt 31, welcher wesentlich länger als die Auskragungen 32 ist, derart dimensioniert ist, daß seine Länge im wesentlichen der Breite der Abdeckung entspricht. Die Breite des mittleren Abschnittes 31 entspricht dabei im wesentlichen der Stegbreite. Somit sind die Verriegelungsfeder 30 von oben nicht ersichtlich und die Arretierung vandalensicher.Figure 3 shows a perspective view of the cover 20 with inserted locking spring 30. The recesses 22 in the Arretierungsstegen 21 are arranged such that the inserted locking spring 30 is mounted with its central portion 31 on the underside of a web 25. From this representation, it can be seen that the central portion 31, which is substantially longer than the projections 32, is dimensioned such that its length substantially corresponds to the width of the cover. The width of the central portion 31 corresponds substantially to the web width. Thus, the locking spring 30 are not visible from above and the lock vandal-proof.

Wie aus den Figuren 1 und 3 ersichtlich, greifen die Haltenasen 34 in die Ausnehmungen 22 der Abdeckung 20 ein und ragen aus diesen heraus. Beim Aufsetzen der Abdeckung 20 mit eingesteckter Verriegelungsfeder 30 auf den Rinnenkörper 10 gleiten die Haltenasen 34 an den abgewinkelten Zargenabschnitt 15 entlang unter Ausüben einer Druckkraft. Die ersten abgewinkelten Abschnitte 33 der Auskragungen 32 werden in Richtung des Rinneninneren so lange bewegt, bis der Bereich der Aussparungen 13 der Rinnenwände 11 erreicht wird und die Haltenasen 34 unter den Zargenabschnitt 15 einschnappen. Dadurch wird eine Verriegelung der Abdeckung 20 auf dem Rinnenkörper 10 erreicht. Durch Ausüben einer Zugkraft, welche wesentlich höher als die Druckkraft ist, kann die Verriegelung gelöst werden, indem die abgewinkelten Abschnitte 33 der Auskragungen 32 in Richtung des Rinneninneren bewegt werden, bis die Haltenasen aus der Arretierungsfläche 17 des Zargenabschnittes 15 gelöst werden. Somit kann die Abdeckung leicht abgehoben werden.As can be seen from Figures 1 and 3, the retaining tabs 34 engage in the recesses 22 of the cover 20 and protrude therefrom. When placing the cover 20 with inserted locking spring 30 on the channel body 10, the retaining lugs 34 slide along the angled frame portion 15 while exerting a compressive force. The first angled portions 33 of the projections 32 are moved in the direction of the channel interior until the area of the recesses 13 of the channel walls 11 is reached and the retaining tabs 34 snap under the frame portion 15. As a result, a locking of the cover 20 on the channel body 10 is achieved. By exerting a tensile force which is significantly higher than the compressive force, the lock can be solved by the angled portions 33 of the projections 32 are moved in the direction of the channel interior until the retaining lugs are released from the locking surface 17 of the frame portion 15. Thus, the cover can be easily lifted.
