Description

Die Erfindung betrifft eine Entwässerungsvorrichtung für die Oberfiächenentwässerung, insbesondere Entwässerungsrinne, mit einem, vorzugsweise länglichen, Grundkörper, einem eine Öffnung des Grundkörpers abdeckenden Deckel, vorzugsweise Abdeckrost, sowie mit mindestens einer rastenden Verriegelungseinrichtung zur rastenden Verriegelung des Deckels am Grundkörper, wobei die Verriegelungseinrichtung mindestens ein erstes Rastelement am Grundkörper und mindestens ein mit dem ersten Rastelement in direkt rastenden Eingriff bringbares, einstückig mit dem Deckel ausgebildetes zweites Rastelement aufweist, wobei am Deckel mindestens ein in Richtung auf den Boden des Grundkörpers ragender Vorsprung angeformt und das zweite Rastelement an einem vom Deckel entfernten Abschnitt des Vorsprunges angeordnet ist.The invention relates to a drainage device for Oberfiächenentwässerung, in particular drainage channel, with a, preferably elongated, body, an opening of the body covering lid, preferably cover grate, as well as with at least one latching locking means for latching locking the lid on the base body, wherein the locking device at least one first latching element on the base body and at least one engageable with the first latching element in direct latching engagement integrally formed with the lid second latching element, wherein formed on the lid at least one protruding toward the bottom of the body protrusion and the second locking element on a remote from the lid Section of the projection is arranged.

Entwässerungsvorrichtungen der gattungsgemäßen Art finden insbesondere in Verkehrsflächen für Fahrzeuge, Radfahrer oder Fußgänger Einsatz und sind beispielsweise als Entwässerungsrinnen ausgebildet. Zu Zwecken der einfachen Montage, Wartung und Reinigung ist es notwendig, dass die Abdeckroste leicht von der Entwässerungsvorrichtung abgenommen und wieder aufgesetzt werden können. Der Forderung nach möglichst einfacher Bedienbarkeit der Abdeckroste steht andererseits die Notwendigkeit entgegen, die Verankerung der Abdeckroste zur Bannung der Unfallgefahr vor dem unbeabsichtigten Lösen zu sichern. Auch häufige Betätigung oder dauerhafte mechanische Belastung, beispielsweise durch Fahrzeugverkehr, soll dabei nach Möglichkeit nicht die Verankerung des Abdeckrostes lockern. In einer Richtung winklig zur Ebene des Deckels elastisch ausgebildet bedeutet, dass bei Krafteinwirkung der das zweite Rastelement tragende Abschnitt und/oder der das erste Rastelement tragende Abschnitt aufgrund der durch die Elastizität bewirkten Nachgiebigkeit einer Schwenkbewegung in eine Richtung winklig zur Ebene des Deckels unterworfen wird, wobei durch die Elastizität gleichzeitig ein Rückstellmoment in genau entgegengesetzter Richtung entsteht.Drainage devices of the generic type are used in particular in traffic areas for vehicles, cyclists or pedestrians use and are designed for example as drainage channels. For ease of assembly, maintenance and cleaning, it is necessary for the grates to be light removed from the dewatering device and can be replaced. The demand for the simplest possible usability of the grids on the other hand is contrary to the need to secure the anchoring of the grids to ban the risk of accident from unintentional release. Frequent actuation or permanent mechanical stress, for example due to vehicle traffic, should also not loosen the anchoring of the cover grille if possible. Being elastically formed in an angular direction to the plane of the lid means that when force is applied, the portion carrying the second detent element and / or the portion carrying the first detent element is subjected to pivotal movement in one direction at an angle to the plane of the lid, due to the resilience caused by the elasticity. wherein at the same time a restoring moment arises in exactly opposite direction by the elasticity.

Die WO-A-02/090675, die den nächstkommenden Stand der Technik angibt, von dem die vorliegende Erfindung ausgeht, offenbart eine Vorrichtung der eingangs genannten Art. Bei dieser bekannten Vorrichtung ist eine Verriegelungsfeder vorgesehen, die aus Blech herstellt ist und gegenüber der Abdeckung ein getrenntes Bauteil bildet. Diese Verriegelungsfeder weist abgewickelte Abschnitte auf, die sich in Richtung auf den Boden des Grundkörpers erstrecken.WO-A-02/090675, which sets forth the closest prior art from which the present invention is based, discloses a device of the kind set forth. In this known device a locking spring is provided which is made of sheet metal and opposite the cover forms a separate component. This locking spring has developed portions which extend in the direction of the bottom of the main body.

Aus dem Stand der Technik ist auch eine Vielzahl von andersartig konstruierten Befestigungseinrichtungen bekannt, die eine Verankerung des Abdeckrostes an der Entwässerungsvorrichtung bewirken sollen. Neben Systemen, die den Abdeckrost mit der Entwässerungsvorrichtung verschrauben, ist beispielsweise aus der EP-A-0 811 732 ein Abdeckrost bekannt, bei dem der Abdeckrost seitlich durch Klemmung mittels besonders ausgestalteter, längselastischer Stege festgelegt werden soll. An beweglichen Enden der Längsstege angeordnete Nocken greifen dabei im eingerasteten Zustand in entsprechende seitlich angeordnete Aussparungen am Grundkörper. Nachteilig an diesen bekannten Entwässerungsvorrichtungen ist, dass sie häufig besondere Werkzeuge zur Arretierung des Abdeckrostes am Grundkörper erfordern. Weiterhin erlauben zwar die teils sehr komplexen Verriegelungseinrichtungen ein sicheres Anliegen des Abdeckrostes am Rinnenkörper, jedoch sind sie bei der Wartung nur mit erheblichen Aufwand lösbar. Schon aufgrund der Zweckbestimmung lagern sich in jeder von der Oberfläche aus zugänglichen Ausnehmung der Entwässerungsvorrichtung Sedimente aus Erde, Sand und organischem Material ab. Gerade in diesen Bereichen liegen bei herkömmlichen Entwässerungsvorrichtungen zumeist die Betätigungs- und Rastelemente für die Arretierung der Abdeckroste am Grundkörper der Entwässerungsvorrichtung.From the prior art, a variety of differently constructed fasteners is known to effect anchoring of the cover to the dewatering device. In addition to systems that screw the cover grate with the dewatering device, a cover grate is known for example from EP-A-0 811 732, in which the cover grate is to be determined laterally by clamping by means of particularly ausgestalteter, longitudinally elastic webs. At the movable ends of the longitudinal webs arranged cams engage in the locked state in corresponding laterally arranged Recesses on the base body. A disadvantage of these known drainage devices is that they often require special tools for locking the cover grating on the base body. Furthermore, although the sometimes very complex locking devices allow a safe concern of the cover grating on the gutter body, but they are solvable during maintenance only with considerable effort. Already due to the purpose, sediments of soil, sand and organic material are deposited in each recess of the drainage device that is accessible from the surface. Especially in these areas are in conventional dewatering devices mostly the actuating and locking elements for locking the Abdeckroste on the main body of the dewatering device.

Aufgabe der vorliegenden Erfindung ist es daher, eine Entwässerungsvorrichtung für die Oberflächenentwässerung der gattungsgemäßen Art bereitzustellen, die bei der Herstellung, Montage und Wartung einen geringeren Aufwand und somit auch geringere Kosten erfordert und bei der eine Verriegelung des Abdeckrostes mit dem Grundkörper in besonders einfacher, aber auch sicherer Weise erfolgen kann. Dabei soll außerdem auf den Einsatz von Sonderwerkzeugen für die Montage bzw. spätere Wartung der Entwässerungsvorrichtung verzichtet werden. Weiterhin soll die Verriegelungsvorrichtung derart ausgestaltet sein, dass sie auch bei erheblichen Eintrag von Sedimenten noch leicht lösbar und leicht zu reinigen ist.Object of the present invention is therefore to provide a drainage device for the surface drainage of the generic type, which requires less effort and thus lower costs in the production, installation and maintenance and in a locking of the cover grid with the main body in a particularly simple, but can also be done safely. It should also be dispensed with the use of special tools for assembly and subsequent maintenance of the dewatering device. Furthermore, the locking device should be designed such that it is still easily solvable and easy to clean even with significant entry of sediments.

Diese Aufgabe wird erfindungsgemäß gelöst durch eine Entwässerungsvorrichtung für die Oberflächenentwässerung, insbesondere Entwässerungsrinne, mit einem, vorzugsweise länglichen, Grundkörper, einem eine Öffnung des Grundkörpers abdeckenden Deckel, vorzugsweise Abdeckrost, sowie mit mindestens einer rastenden Verriegelungseinrichtung zur rastenden Verriegelung des Deckels am Grundkörper, wobei die Verriegelungseinrichtung mindestens ein erstes Rastelement am Grundkörper und mindestens ein mit dem ersten Rastelement in direkt rastenden Eingriff bringbares, einstückig mit dem Deckel ausgebildetes zweites Rastelement aufweist, wobei am Deckel mindestens ein in Richtung auf den Boden des Grundkörpers ragender Vorsprung angeformt und das zweite Rastelement an einem vom Deckel entfernten Abschnitt des Vorsprunges angeordnet ist, dadurch gekennzeichnet, dass der vom Deckel entfernte Abschnitt des Vorsprunges breiter als der übrige Abschnitt des Vorsprunges ist und vorzugsweise etwa die Form eines sich etwa parallel zur Ebene des Deckels erstreckenden Stabes besitzt.This object is achieved by a dewatering device for surface drainage, especially drainage channel, with a, preferably elongated body, a cover of the base covering a cover, preferably cover grate, as well as with at least one latching locking device for latching locking the lid on the body, said Locking device has at least one first locking element on the base body and at least one engageable with the first locking element in direct latching engagement integrally formed with the lid second locking element, wherein formed on the cover at least one projecting towards the bottom of the body protrusion and the second Detent element is disposed on a portion of the projection remote from the lid, characterized in that the portion of the projection remote from the lid is wider than the remaining portion of the projection and preferably has approximately the shape of a rod extending approximately parallel to the plane of the lid.

Demnach sind erfindungsgemäß die Rastelemente der Verriegelungseinrichtung integrale Bestandteile des Deckels bzw. des Grundkörpers. Es sind somit keine weiteren Verriegelungselemente oder sonstigen Bestandteile, wie beispielsweise Schrauben, Klammern o.dgl., für die Arretierung notwendig. Auf diese Weise wird erfindungsgemäß erreicht, dass die Entwässerungsvorrichtung aus weniger Komponenten besteht. Dies führt zu einem geringeren Aufwand bei der Herstellung, Montage und Wartung, was sich entsprechend positiv auf die damit verbundenen Kosten auswirkt. Gleiches gilt auch im Hinblick darauf, dass aufgrund der erfindungsgemäßen Konstruktion der Einsatz von Sonderwerkzeugen für die Montage und spätere Wartung der Entwässerungsvorrichtung überflüssig wird. Schließlich kann aufgrund der besonderen Lage und Ausgestaltung der Verriegelungseinrichtung der Abdeckrost auch noch bei erheblichem Eintrag von Erde, Sand oder organischem Material betätigt werden.Accordingly, according to the invention, the latching elements of the locking device are integral components of the lid or the base body. There are thus no further locking elements or other components, such as screws, brackets or the like., For locking necessary. In this way it is achieved according to the invention that the dewatering device consists of fewer components. This leads to less effort in the production, installation and maintenance, which has a correspondingly positive effect on the associated costs. The same applies in view of the fact that due to the construction according to the invention the use of special tools for assembly and subsequent maintenance of the dewatering device is unnecessary. Finally, due to the particular position and design of the locking device, the cover grate can be actuated even with considerable input of earth, sand or organic material.

Gemäß einer bevorzugten Ausgestaltung der Erfindung ist zumindest ein das zweite Rastelement tragender Abschnitt des Vorsprungs und/oder zumindest ein das erste Rastelement tragender Abschnitt des Grundkörpers, vorzugsweise in einer Richtung winklig zur Ebene des Deckels, elastisch ausgebildet. Hierdurch kann in einfacher Weise ein Einrasten der beiden Rastelemente unterstützt sowie das Aufsetzen des Deckels auf den Grundkörper erleichtert werden. Demnach sind bei dieser Ausführung die das erste Rastelement und/oder das zweite Rastelement tragenden Abschnitte elastisch verschwenkbar um eine gedachte Schwenkachse ausgebildet, die vorzugsweise parallel zur Ebene des Deckels verläuft oder in dieser liegt.According to a preferred embodiment of the invention, at least one portion of the projection bearing the second latching element and / or at least one portion of the base body carrying the first latching element, preferably in an angular direction to the plane of the lid, are designed to be elastic. In this way, a snap-in engagement of the two latching elements can be supported in a simple manner and the placement of the lid on the base body can be facilitated. Accordingly, in this embodiment, the first latching element and / or the second latching element bearing portions are elastically pivotable about an imaginary pivot axis, which preferably extends parallel to the plane of the lid or lies in this.

Weiterhin ist bevorzugt, dass die das erste und/oder zweite Rastelement tragenden Abschnitte jeweils eine Ebene aufspannen, die winklig, vorzugsweise quer, zur Längserstreckung des Grundkörpers verläuft. Damit wird erreicht, dass ein Entriegeln der Verriegelungseinrichtung bei in Längsrichtung auf den Deckel der Entwässerungsvorrichtung wirkenden Kräften erschwert oder gänzlich verhindert wird.Furthermore, it is preferred that the portions carrying the first and / or second latching element each span a plane which is angled, preferably transversely, extends to the longitudinal extent of the body. This ensures that unlocking the locking device is made difficult or completely prevented when acting in the longitudinal direction of the lid of the dewatering device forces.

Vorzugsweise weist der Deckel Rippen, insbesondere zur Versteifung, auf, wobei der Vorsprung von einer Rippe gebildet oder an einer Rippe angeordnet, vorzugsweise angeformt ist. Insbesondere sind die Rippen zumindest teilweise als sich zwischen Längsseiten des Deckels erstreckende Querrippen ausgebildet und der Vorsprung befindet sich an diesen Querrippen. Vorgenannte Ausführungsform der Verriegelungseinrichtung lässt sich fertigungstechnisch besonders einfach realisieren, so dass die Herstellungskosten der Entwässerungsvorrichtung insgesamt gesenkt werden können.Preferably, the cover ribs, in particular for stiffening, on, wherein the projection is formed by a rib or arranged on a rib, preferably formed. In particular, the ribs are at least partially formed as between longitudinal sides of the lid extending transverse ribs and the projection is located on these transverse ribs. The aforementioned embodiment of the locking device can be particularly easily realized in terms of manufacturing technology, so that the manufacturing costs of the dewatering device can be reduced overall.

In einer bevorzugten Ausgestaltung der Erfindung umfassen die ersten und zweiten Rastelemente komplementäre Aussparungen und Verdickungen. Diese können vorzugsweise derart ausgestaltet sein, dass das erste Rastelement am Grundkörper ein Kamm und das zweite Rastelement eine komplementäre Nut besitzt. Die im Prinzip bei der Fertigung sehr einfach realisierbaren und damit mit geringen Herstellungskosten verbundenen Ausgestaltungen der Rastelemente haben sich als sehr robust gegenüber Umwelteinflüssen und mechanischer Belastung erwiesen. Sollte es zu Verschmutzungen oder zum Eintrag von Sedimenten im Bereich der Rastelemente kommen, so ist eine Reinigung der Rastelemente, beispielsweise mittels Hochdruck-Wasserreinigung, besonders einfach möglich, da alle Bestandteile der Verriegelungseinrichtung leicht zugänglich sind.In a preferred embodiment of the invention, the first and second latching elements comprise complementary recesses and thickenings. These may preferably be configured such that the first detent element on the main body has a comb and the second detent element has a complementary groove. The embodiments of the latching elements, which are in principle very easy to realize in production and therefore associated with low production costs, have proven to be very robust against environmental influences and mechanical stress. Should it come to contamination or entry of sediments in the catch elements, so a cleaning of the locking elements, for example by means of high-pressure water purification, particularly easy, since all components of the locking device are easily accessible.

Es sind aber auch andere konstruktive Möglichkeiten denkbar, um die ersten und zweiten Rastelemente miteinander in rastenden Eingriff zu bringen. So können beispielsweise alternativ die ersten und zweiten Rastelemente miteinander in Eingriff bringbare Rastnasen aufweisen. Gewöhnlich sind die Rastnasen der ersten und zweiten Rastelemente aufeinander zugerichtet und hintergreifen einander in der Arretierungsstellung und somit im Schließzustand der Verriegelungseinrichtung.But there are also other design possibilities are conceivable to bring the first and second locking elements together in latching engagement. Thus, for example, alternatively, the first and second locking elements having mutually engageable locking lugs. Usually, the locking lugs of the first and second locking elements are aligned with each other and engage behind each other in the locking position and thus in the closed state of the locking device.

Femer ist bevorzugt, dass der Grundkörper mindestens eine Auflagefläche für den Deckel aufweist, im Bereich der Auflagefläche eine Vertiefung ausgebildet und das erste Rastelement innerhalb der Vertiefung angeordnet ist. Wenn der Grundkörper eine Zarge aufweist, die zur Aufnahme des Deckels dient, dann ist vorzugsweise das erste Rastelement in die Zarge integriert. Mit den genannten Maßnahmen kann erreicht werden, dass ein Verschieben des Abdeckrostes aufgrund mechanischer Belastung in Längsrichtung verhindert wird. Weiterhin wird die Montage und erneute Positionierung des Abdeckrostes nach Wartung auf dem Grundkörper erleichtert, denn die Ausgestaltung der Rastelemente unterstützt die Vorpositionierung des Abdeckrostes auf dem Grundkörper. Das zweite Rastelement ragt im zusammengesetzten Zustand der Entwässerungsvorrichtung in die Vertiefung des Grundkörpers und steht mit dem ersten Rastelement im einrastenden Eingriff.Furthermore, it is preferred that the base body has at least one bearing surface for the cover, a depression is formed in the region of the bearing surface and the first detent element is arranged within the depression. If the base body has a frame which serves to receive the lid, then preferably the first latching element is integrated into the frame. With the above measures can be achieved that a displacement of the cover grating is prevented due to mechanical load in the longitudinal direction. Furthermore, the assembly and repositioning of the cover after maintenance on the base body is facilitated, because the design of the locking elements supports the pre-positioning of the cover on the base body. The second locking element protrudes in the assembled state of the dewatering device in the recess of the body and communicates with the first locking element in latching engagement.

Bei einer weiteren bevorzugten Ausführung der Erfindung ist eine Einrichtung zur verschiebesicheren Anordnung des Deckels am Grundkörper vorgesehen. Mit Hilfe einer solchen Einrichtung wird der Deckel am Grundkörper so fixiert, dass er sich gegenüber dem Grundkörper nicht verschieben lässt, wenn durch äußere Einwirkung Kräfte in den Deckel in Richtung dessen Erstreckung eingeleitet werden. Derartige in Längs- und/oder Querrichtung wirkende Kräfte treten hauptsächlich dann auf, wenn der Deckel von Fahrzeugen überfahren wird. Dabei entstehen insbesondere beim Abbremsen oder Beschleunigen besonders hohe Kräfte dieser Art. Aufgrund solcher Kräfte neigt der Deckel zu einer Verschiebung gegenüber dem Grundkörper. Dadurch wird die Verriegelungseinrichtung einer erhöhten Belastung ausgesetzt, und es besteht möglicherweise die Gefahr eines schnelleren Verschleißes oder sogar einer Beschädigung. Mit Hilfe der erwähnten Einrichtung wird dagegen eine Verschiebesicherung geschaffen, die ein unbeabsichtigtes Verschieben verhindert, indem sie die in die Ebene des Deckels eingeleiteten Kräfte aufnimmt und dadurch die Verriegelungseinrichtung entlastet.In a further preferred embodiment of the invention, a device for the secure displacement arrangement of the lid is provided on the base body. With the help of such a device, the lid on the base body is fixed so that it can not be moved relative to the main body when forces are introduced into the lid in the direction of its extension by external action. Such acting in the longitudinal and / or transverse forces occur mainly when the lid is run over by vehicles. In particular, when braking or accelerating particularly high forces of this kind arise. Due to such forces, the lid tends to shift relative to the main body. As a result, the locking device is exposed to an increased load, and there is a risk of faster wear or even damage. With the help of the mentioned device, however, a displacement protection is provided which prevents unintentional displacement by receiving the forces introduced into the plane of the lid and thereby relieves the locking device.

Eine Weiterbildung der zuvor genannten Ausführung zeichnet sich dadurch aus, dass die Einrichtung zur verschiebesicheren Anordnung des Deckels mindestens ein Paar von miteinander in Eingriff bringbaren Eingriffsmitteln aufweist, von denen das erste Eingriffsmittel am Deckel und das zweite Eingriffsmittel am Grundkörper angeordnet ist. Dabei kann das erste Eingriffsmittel mindestens eine Nase und das zweite Eingriffsmittel mindestens eine Aussparung zur Aufnahme mindestens einer Nase aufweisen; eine umgekehrte Ausbildung ist aber ebenfalls denkbar. Wenn der Grundkörper mit mindestens einer Auflagefläche für den Deckel versehen ist, kann zweckmäßigerweise das erste Eingriffsmittel an der Unterseite des Deckels und das zweite Eingriffsmittel auf der Auflagefläche des Grundkörpers ausgebildet sein. Bei einer besonders bevorzugten Weiterbildung erhebt sich die Nase von der Auflagefläche und bildet die Aussparung an der Unterseite des Deckels eine entsprechende Vertiefung, in die die Nase eingreift, um den Deckel verschiebefest gegenüber der Auflagefläche am Grundkörper zu fixieren. Für den Fall, dass der Deckel Rippen aufweist, mit deren Randabschnitten der Deckel auf der Auflagefläche am Grundkörper aufliegt, kann vorzugsweise mindestens eine Aussparung durch die Lücke zwischen zwei benachbarten Randabschnitten der Rippen gebildet sein.A development of the aforementioned embodiment is characterized in that the device for non-shift arrangement of the lid at least a pair of engageable engaging means, of which the first engaging means on the lid and the second engaging means on the base body is arranged. In this case, the first engagement means at least one nose and the second engagement means have at least one recess for receiving at least one nose; a reverse training is also conceivable. If the base body is provided with at least one support surface for the cover, the first engagement means on the underside of the cover and the second engagement means can expediently be formed on the support surface of the base body. In a particularly preferred embodiment, the nose rises from the support surface and forms the recess on the underside of the lid, a corresponding recess into which the nose engages to fix the cover against the support surface against the base body. In the event that the lid has ribs, with whose edge portions the lid rests on the bearing surface on the base body, preferably at least one recess can be formed by the gap between two adjacent edge portions of the ribs.

Üblicherweise weist der Grundkörper mindestens einen Seitenwandabschnitt auf; in diesem Fall kann die Einrichtung zur verschiebesicheren Anordnung des Deckels alternativ oder zusätzlich zu der zuvor beschriebenen Ausführung mindestens einen Anschlag zur Anlage an den Seitenwandabschnitt aufweisen, um eine weitere verschiebesichere Arretierung zu bilden. Sofern der Grundkörper mindestens eine Auflagefläche für den Deckel aufweist, unterhalb derer sich der Seitenwandabschnitt befindet, kann der Anschlag einen an der Unterseite des Deckels angeordneten Fortsatz bilden.Usually, the base body has at least one side wall section; In this case, the means for non-shiftable arrangement of the lid may alternatively or in addition to the above-described embodiment, at least one stop for abutment against the side wall portion to form a further non-locking lock. If the base body has at least one support surface for the cover, below which the side wall section is located, the stop can form an extension arranged on the underside of the cover.

Wenn der Grundkörper eine Zarge aufweist, die zur Aufnahme des Deckels dient, ist es schließlich zweckmäßig, das zweite Eingriffsmittel an der Zarge auszubilden.When the body has a frame which serves to receive the lid, it is finally appropriate to form the second engagement means on the frame.

Weitere bevorzugte Ausgestaltungen der Erfindung ergeben sich im Übrigen aus den in den Unteransprüchen genannten Merkmalen.Other preferred embodiments of the invention will be apparent from the features mentioned in the dependent claims.

Die Figur 1 zeigt schematisch eine Draufsicht auf eine Entwässerungsrinne 10 zur Oberflächenentwässerung gemäß einem ersten Ausführungsbeispiel, wie sie typischerweise in Verkehrsflächen eingesetzt wird. Die Entwässerungsvorrichtung 10 setzt sich aus einem Abdeckrost 22 und einem Grundkörper 12 zusammen. Vom Grundkörper 12 ist aus der Perspektive der Figur 1 lediglich ein in Längsrichtung der Entwässerungsvorrichtung 10 verlaufender Rahmen 14 zu erkennen. Die Oberseiten des Abdeckrostes 22 und des Rahmens 14 bilden eine Ebene, die als Verkehrsfläche dient.1 shows schematically a plan view of a drainage channel 10 for surface drainage according to a first embodiment, as it is typically used in traffic areas. The dewatering device 10 is composed of a cover grid 22 and a base body 12. From the basic body 12, only a frame 14 running in the longitudinal direction of the dewatering device 10 can be seen from the perspective of FIG. The tops of the cover grille 22 and the frame 14 form a plane that serves as a traffic area.

Details zum Aufbau des Grundkörpers 12 lassen sich den Figuren 2 und 3 entnehmen, die Schnittansichten entlang der Linien II-II bzw. III-III der Figur 1 zeigen. Der Grundkörper 12 weist eine in der Ebene der Verkehrsfläche liegende längliche Öffnung 16 auf, die in einen Rinnenkörper 17 mündet und im zusammengesetzten Zustand der Entwässerungsrinne 10 vom Abdeckrost 22 abgedeckt wird. Durch die Öffnung 16 eindringendes Wasser wird am Boden 18 des Rinnenkörper 17 gesammelt und abgeführt.Details of the structure of the main body 12 can be taken from Figures 2 and 3, the sectional views along the lines II-II and III-III of Figure 1 show. The main body 12 has an elongated opening 16 lying in the plane of the traffic surface, which opens into a channel body 17 and is covered by the cover grid 22 in the assembled state of the drainage channel 10. Water entering through the opening 16 is collected and removed at the bottom 18 of the channel body 17.

Aus den Figuren 2 und 3 wird ferner deutlich, dass der Grundkörper 12 gemäß dem dargestellten Ausführungsbeispiel eine auf den dem Rinnenkörper 17 aufgesetzte Zarge 19 aufweist. Ein vergrößerter Ausschnitt der Zarge 19 ist ferner in Figur 8 gezeigt. Die Zarge 19 bildet, wie in den Figuren 3 und 8 zu erkennen ist, an ihren zur Innenseite des Grundkörpers 12 gerichteten Seiten jeweils einen von der Ebene der Verkehrsfläche nach unten beabstandeten Absatz 20 aus. Dieser Absatz 20 weist eine plane, horizontal ausgerichtete Oberseite auf, die als Auflagefläche 21 für den Abdeckrost 22 dient. Zur Schalldämpfung ist üblicherweise eine von der Oberseite des Absatzes abstehende elastische Kunststoffeinlage 24 vorgesehen. Der Grundkörper 12 kann beispielsweise aus Beton und die Zarge 19 aus einem korrosionsbeständigen Metall oder Kunststoff bestehen.From the figures 2 and 3 it is further clear that the base body 12 according to the illustrated embodiment has a patch on the gutter body 17 frame 19. An enlarged section of the frame 19 is also shown in FIG. The frame 19 forms, as can be seen in Figures 3 and 8, at their directed to the inside of the body 12 sides each one of the plane of the traffic surface downwardly spaced paragraph 20 from. This paragraph 20 has a flat, horizontally oriented top, which serves as a support surface 21 for the cover 22. For sound attenuation, an elastic plastic insert 24 projecting from the top of the heel is usually provided. The main body 12 may for example consist of concrete and the frame 19 made of a corrosion-resistant metal or plastic.

Die Ebene 15 der Verkehrsfläche des Abdeckrostes 22 wird im dargestellten Ausführungsbeispiel von einem äußeren Umlaufsteg 26, fünf Längsöffnungen 27 und vier entsprechend voneinander beabstandeten, parallelen Längsstegen 28 gebildet. Der Umlaufsteg 26 ist an seinen beiden Längsseiten etwas verbreitert und liegt im zusammengesetzten Zustand der Entwässerungsvorrichtung 10, wie im Querschnitt der Figur 3 zu erkennen, mit seiner Unterseite auf der Auflagefläche 21 der länglichen Vorsprüngen 20 bzw. auf deren elastischen Kunststoffeinlagen 24.The plane 15 of the traffic surface of the Abdeckrostes 22 is formed in the illustrated embodiment by an outer circumferential web 26, five longitudinal openings 27 and four correspondingly spaced apart, parallel longitudinal webs 28. The circumferential web 26 is slightly widened at its two longitudinal sides and lies in the assembled state of the dewatering device 10, as can be seen in the cross section of Figure 3, with its underside on the support surface 21 of the elongated projections 20 and on the elastic plastic inserts 24th

Unterhalb der die Verkehrsfläche des Abdeckrostes 22 bildenden Umlauf- und Längsstege 26, 28 erstrecken sich Querrippen 32 zwischen den Längsseiten des Abdeckrostes 22 (in Figur 1 nur teilweise sichtbar). Die Querrippen 32 sind einstückig mit den weiteren Elementen des Abdeckrostes 22, also insbesondere den Umlauf- und Längsstegen 26, 28, verbunden und dienen im Wesentlichen der Versteifung des Abdeckrostes 22.Below the circulation surface and longitudinal webs 26, 28 forming the traffic surface of the cover grating 22, transverse ribs 32 extend between the longitudinal sides of the cover grate 22 (only partially visible in FIG. 1). The transverse ribs 32 are integral with the other elements of the Abdeckrostes 22, ie in particular the circumferential and longitudinal webs 26, 28, connected and serve essentially the stiffening of the cover grille 22nd

Aus dem in Figur 2 dargestellten Schnitt entlang der Linie II-II der Figur 1 ist eine relative Lage der einzelnen Querrippen 32 im Abdeckrost 22 ersichtlich. Zwei der in Figur 2 im Querschnitt dargestellten Querrippen 32 sind mit in Richtung des Bodens 18 des Grundkörpers 12 weisenden Laschen oder Vorsprünge 34, 36 versehen, an denen Verriegelungseinrichtungen 38, 40 angeordnet-sind. Selbstverständlich können auch an weiteren Querrippen 32 Verriegelungseinrichtungen vorgesehen sein.From the section shown in Figure 2 along the line II-II of Figure 1 is a relative position of the individual transverse ribs 32 in the cover grid 22 can be seen. Two of the transverse ribs 32 shown in cross-section in Figure 2 are provided with in the direction of the bottom 18 of the body 12 facing tabs or projections 34, 36, on which locking means 38, 40 are arranged. Of course, 32 locking devices can be provided on further transverse ribs.

In Figur 4 ist beispielhaft ein vergrößerter Teilausschnitt der Entwässerungsvorrichtung 10 im Bereich der Verriegelungseinrichtung 40 und zwar entlang der Linie IV-IV der Figur 1 dargestellt. Die Verriegelungseinrichtung 40 umfasst ein erstes Rastelement 42 am Grundkörper 12 und ein mit dem ersten Rastelement 42 in direkt einrastendem Eingriff bringbares zweites Rastelement 44 am Abdeckrost 22.4 shows by way of example an enlarged partial section of the dewatering apparatus 10 in the region of the locking device 40, specifically along the line IV-IV of FIG. 1. The locking device 40 comprises a first latching element 42 on the base body 12 and a second latching element 44, which can be brought into direct latching engagement with the first latching element 42, on the cover grille 22.

Das erste Rastelement 42 ist gemäß dem dargestellten ersten Ausführungsbeispiel als quer zur Längserstreckung des Grundkörpers 12 verlaufender Kamm ausgebildet und sitzt etwa mittig an einer Seitenwandung 50 eines an der Innenseite der Zarge 19 vorgesehenen, nach unten gerichteten U-förmigen Abschnittes 50, der im Absatz 20 eine Vertiefung bzw. eine Art Sicke bildet. Die das erste Rastelement 42 tragende Seitenwandung 50 spannt eine Ebene auf, die quer zur Längserstreckung des Grundkörpers 12 verläuft.The first latching element 42 is formed according to the illustrated first embodiment as extending transversely to the longitudinal extent of the base body 12 comb and is located approximately centrally on a side wall 50 of a provided on the inside of the frame 19, downwardly directed U-shaped portion 50, in the paragraph 20th forms a depression or a kind of bead. The side wall 50 carrying the first latching element 42 spans a plane that runs transversely to the longitudinal extent of the base body 12.

Das zweite Rastelement 44 ist gemäß dem dargestellten ersten Ausführungsbeispiel als eine quer zur Längserstreckung des Grundkörpers 12 verlaufende und zum Kamm des ersten Rastelementes 42 komplementäre Nut ausgebildet und an einer Seitenwandung 56 des Vorsprunges 36 der Querrippe 32 angeordnet. Der das zweite Rastelement 44 tragende Vorsprung 36 spannt eine Ebene auf, die quer zur Längserstreckung des Grundkörpers 12 verläuft. Demnach ist im dargestellten ersten Ausführungsbeispiel das zweite Rastelement 44 einstückig mit dem Abdeckrost 22 verbunden. Das als Nut vorgesehene zweite Rastelement 44 ist an beiden Seitenenden 54a eines unteren Endabschnittes 54 des Vorsprunges 36 ausgebildet. Wie Figur 3 erkennen lässt, erstreckt sich der untere Endabschnitt 54 mit seinen beiden Seitenenden 54a etwa über die gesamte Breite des Deckels 22, während der übrige Vorsprung 36 eine geringere Breite besitzt.The second locking element 44 is formed according to the illustrated first embodiment as a transverse to the longitudinal extent of the body 12 and complementary to the comb of the first locking element 42 groove and disposed on a side wall 56 of the projection 36 of the transverse rib 32. The projection 36 supporting the second latching element 44 spans a plane that runs transversely to the longitudinal extent of the base body 12. Accordingly, in the illustrated first embodiment, the second locking element 44 is integrally connected to the cover grid 22. The intended as a groove second locking element 44 is formed on both side ends 54 a of a lower end portion 54 of the projection 36. As Figure 3 reveals, the lower end portion 54 extends with its two side ends 54a about the entire width of the lid 22, while the remaining projection 36 has a smaller width.

Bei den Verriegelungseinrichtungen 38, 40 der Figur 2 sind die einzelnen Rastelemente 42, 44 jeweils an voneinander weggewandten Seitenwandungen der sie tragenden und an einer Querrippe 32 angeformten Vorsprünge 34, 36 angeordnet. Obwohl die Vorsprünge 34, 36 über die jeweilige Querrippe 32 am Abdeckrost 22 im Wesentlichen starr angeformt sind, besitzen sie gleichwohl eine gewisse Elastizität, so dass sie nach dem Einrasten des Abdeckrostes 22 unter leichter Spannung stehen und dadurch die notwendige Haltekraft der Verriegelungseinrichtungen 38, 40 und somit die Arretierung realisiert wird.In the locking devices 38, 40 of Figure 2, the individual locking elements 42, 44 respectively on mutually facing away from the side walls of the supporting and integrally formed on a transverse rib 32 projections 34, 36 are arranged. Although the projections 34, 36 are substantially rigidly formed over the respective transverse rib 32 on the cover grille 22, they nevertheless have a certain elasticity, so that they are under slight tension after the latching grate 22 engages, and thereby the necessary holding force of the locking devices 38, 40 and thus the locking is realized.

Zur Montage wird der Abdeckrost 22 auf den Grundkörper 12 gelegt, wobei die Verriegelungseinrichtungen 38, 40 eine exakte Positionierung erleichtern. Nach dem Auflegen des Abdeckrostes 22 wird dieser senkrecht nach unten gedrückt, wobei die als Kämme ausgestalteten ersten Rastelemente 42 über die Seitenwandungen 56 der Querrippen 32 gleiten, bis sie in die nutenförmigen zweiten Rastelemente 44 greifen. Der das zweite Rastelement 44 tragende Vorsprung 36 der zugehörigen Querrippe 32 und/oder die das erste Rastelement 42 tragende Seitenwandung 50 des eine Vertiefung bildenden U-förmigen Abschnittes 52 an der Zarge 19 sind dabei zur Erleichterung der Montage sowie zur Erzielung der Rastwirkung in einer Richtung winklig zur Ebene 15 des Abdeckrostes 22 elastisch nachgebend ausgebildet.For mounting the cover grid 22 is placed on the base body 12, wherein the locking means 38, 40 facilitate accurate positioning. After placing the covering grate 22, it is pressed downwards vertically, wherein the first latching elements 42 designed as combs slide over the side walls 56 of the transverse ribs 32 until they engage in the groove-shaped second latching elements 44. The second latching element 44 supporting projection 36 of the associated transverse rib 32 and / or the first latching element 42 supporting side wall 50 of a recess forming a U-shaped portion 52 on the frame 19 are to facilitate assembly and to achieve the locking action in one direction formed at an angle to the level 15 of the cover 22 elastically yielding.

Wie Figur 2 ferner erkennen lässt, sind die beiden Verriegelungseinrichtung 38, 40 im dargestellten Ausführungsbeispiel spiegelsymmetrisch zueinander ausgebildet, indem die als Kamm ausgebildeten ersten Rastelementen 42 aufeinander zu und die als Nut ausgebildeten zweiten Rastelemente 44 voneinander weg gerichtet sind. Dies hat zur Folge, dass beim Einrasten des Deckels 22 an der Zarge 19 des Grundkörpers 12 die mit dem zweiten Rastelement 44 versehenen Querrippen 32 einer aufeinander zugerichtete Kippbewegung unterworfen werden, wodurch jeweils wiederum ein in entgegengesetzter Richtung wirkendes Drehmoment zur Erzielung eines Eingriffes des zweiten Rastelementes 44 mit dem ersten Rastelement 42 entsteht. Auf diese Weise bildet jeweils die eine der Verriegelungseinrichtungen 38, 40 ein Widerlager in Bezug auf die andere Verriegelungseinrichtung.As can also be seen from FIG. 2, the two locking devices 38, 40 in the exemplary embodiment shown are mirror-symmetrical to one another in that the first latching elements 42 designed as a comb are directed toward one another and the second latching elements 44 designed as a groove are directed away from one another. As a result, when the lid 22 engages on the frame 19 of the basic body 12, the transverse ribs 32 provided with the second latching element 44 are subjected to a tilting movement directed towards one another, whereby in each case in turn an acting in the opposite direction torque to achieve an engagement of the second locking element 44 with the first locking element 42 is formed. In this way, each one of the locking devices 38, 40 forms an abutment with respect to the other locking device.

Selbstverständlich können die Verriegelungseinrichtungen 38, 40 aber auch in umgekehrter Wirkrichtung spiegelsymmetrisch zueinander ausgebildet sein. Schließlich ist es aber grundsätzlich denkbar, nur eine Verriegelungseinrichtung in der zuvor beschriebenen Weise vorzusehen und gegebenenfalls beabstandet von dieser einen Anschlag auszubilden, der als Widerlager wirkt.Of course, the locking means 38, 40 but also in the opposite effective direction may be formed mirror-symmetrically to each other. Finally, it is conceivable in principle to provide only one locking device in the manner described above and optionally spaced from this form a stop which acts as an abutment.

Neben den hier dargestellten Ausgestaltungen der Rastelemente 42 und 44 können beispielsweise auch Mittel zum Einrasten des Abdeckrostes 22 am Grundkörper 12 vorgesehen sein, die komplementäre Aussparungen und Verdickungen auf den Querrippen 32 bzw. am Grundkörper 12 umfassen. Dabei können auch mehrere derartige Rastelemente auf einer Querrippe 32 und entsprechend im Bereich des Grundkörpers 12 angeordnet werden. So kann bei der gemäß Figur 4 dargestellten Anordnung beispielsweise auch die vom Betrachter aus gesehene linke Seitenwandung der Querrippe 32 bzw. der Vertiefung 52 je ein Rastelement tragen. Die Anordnung der Rastelemente im Bereich senkrecht zur Verkehrsfläche gelegener Wandungen hat sich als besonders sinnvoll erwiesen, weil hierdurch die Ablagerung von Sedimenten im Bereich der Verriegelungseinrichtungen 38, 40 stark zurückgedrängt werden kann.In addition to the embodiments of the latching elements 42 and 44 shown here, means for latching the cover grating 22 to the base body 12 can also be provided, for example, which include complementary recesses and thickenings on the transverse ribs 32 and on the base body 12. In this case, a plurality of such locking elements can be arranged on a transverse rib 32 and correspondingly in the region of the base body 12. Thus, in the arrangement shown according to FIG. 4, for example, the left side wall of the transverse rib 32 or the recess 52, as seen by the observer, may each carry one latching element. The arrangement of the latching elements in the area perpendicular to the traffic surface located walls has proved to be particularly useful, because in this way the deposition of sediment in the locking devices 38, 40 can be strongly suppressed.

In den Figuren 5 bis 7 ist von einem zweiten Ausführungsbeispiel einer Entwässerungsrinne ein Abdeckrost 122 dargestellt. Dieser Abdeckrost 122 eignet sich zur Auflage auf einen Grundkörper, wie er bereits zuvor anhand der Figuren 1 bis 4 beschrieben worden ist. Somit kann der Grundkörper 12 gemäß dem ersten Ausführungsbeispiel ohne wesentliche Änderungen auch für das nachfolgend beschriebene zweite Ausführungsbeispiel verwendet werden. Die Oberseite des Abdeckrostes 122 ist in gleicher oder ähnlicher Weise konfiguriert, wie in Figur 1 anhand des Abdeckrostes 22 des ersten Ausführungsbeispiels gezeigt ist. Figur 5 zeigt den Abdeckrost 122 mit einem linken halbseitigen Längsschnitt entlang einer Linie entsprechend der Linie II-II von Figur 1, und Figur 6 zeigt einen Querschnitt durch den Abdeckrost 122 entlang einer Linie entsprechend der Linie III-III von Figur 1.FIGS. 5 to 7 show a cover grate 122 of a second exemplary embodiment of a drainage channel. This cover grate 122 is suitable for resting on a base body, as has already been described above with reference to the figures 1 to 4. Thus, the base body 12 can be used according to the first embodiment without significant changes for the second embodiment described below. The top of the cover grate 122 is configured in the same or similar manner as shown in FIG. 1 with reference to the cover grille 22 of the first embodiment. FIG. 5 shows the cover grid 122 with a left half-side longitudinal section a line along the line II-II of Figure 1, and Figure 6 shows a cross section through the Abdeckrost 122 along a line along the line III-III of Figure 1.

Dieser Abdeckrost 122 unterscheidet sich von dem Abdeckrost 22 gemäß dem ersten Ausführungsbeispiel dadurch, dass sich die Querrippen 132 über die gesamte Breite des Abdeckrostes 122 erstrecken und das Abdeckrost 122 nur mit den seitlichen Endabschnitten 132a der Querrippen 132 auf der Auflagefläche 21 des Grundkörpers 12 aufliegt. Somit entstehen bei Auflage des Abdeckrostes 122 auf der Auflagefläche 21 des Grundkörpers 12 zwischen den Endabschnitten 132a jeweils zweier benachbarter Querrippen 132 Lücken, wo der Abdeckrost 122 nicht auf der Auflagefläche 21 der Grundkörpers 12 aufliegt.This cover grille 122 differs from the cover grating 22 according to the first embodiment in that the transverse ribs 132 extend over the entire width of the cover grate 122 and the cover grate 122 rests on the support surface 21 of the base body 12 only with the lateral end sections 132a of the transverse ribs 132. Thus, when the covering grate 122 rests on the supporting surface 21 of the base body 12 between the end portions 132a of two adjacent transverse ribs 132, gaps are created where the grating grille 122 does not rest on the supporting surface 21 of the base body 12.

Ferner unterscheidet sich der Deckel 122 von der ersten Ausführung durch anders ausgebildete Verriegelungseinrichtungen 138, 140. Zwar haben auch die Verriegelungseinrichtungen 138, 140 eine rastende Funktion; jedoch sind bei der zweiten Ausführung die zweiten Rastelemente 144 als keilförmige Rastvorsprünge ausgebildet. Im geschlossenen Zustand untergreifen die als keilförmige Vorsprünge ausgebildeten zweiten Rastelemente 144 die am Grundkörper 12 ausgebildeten ersten Rastelemente, die in gleicher oder ähnlicher Weise wie die ersten Rastelemente 42 bei der ersten Ausführung angeordnet und auch in ähnlicher Weise als Kämme oder Vorsprünge ausgestaltet sind.Furthermore, the cover 122 differs from the first embodiment by differently formed locking devices 138, 140. Although the locking devices 138, 140 have a latching function; However, in the second embodiment, the second locking elements 144 are formed as wedge-shaped locking projections. In the closed state, the second locking elements 144 designed as wedge-shaped projections engage under the first latching elements formed on the main body 12, which are arranged in the same or similar manner as the first latching elements 42 in the first embodiment and are also configured in a similar manner as combs or projections.

Ähnlich wie bei der ersten Ausführung sitzt auch bei der zweiten Ausführung das zweite Rastelement 144 an einem unteren Endabschnitt 154 des Vorsprunges 134 bzw. 136. Anders als bei der ersten Ausführung ist aber bei der zweiten Ausführung das zweite Rastelement 144 als Stab ausgebildet, der sich parallel zur Ebene des Abdeckrostes 122 über die gesamte Breite des Abdeckrostes 122 erstreckt, während der das zweite Rastelement 144 tragende Vorsprung 134 bzw. 136 eine deutlich geringere Breite besitzt, wie insbesondere die Figuren 6 und 7 erkennen lassen.Similar to the first embodiment, the second locking element 144 is seated at a lower end portion 154 of the projection 134 and 136, respectively, in the second embodiment. Unlike the first embodiment, however, in the second embodiment, the second locking element 144 is formed as a rod which extends extends parallel to the plane of the Abdeckrostes 122 over the entire width of the Abdeckrostes 122, while the second locking element 144 supporting projection 134 and 136 has a significantly smaller width, as can be seen in particular Figures 6 and 7.

Im Übrigen entspricht die Konstruktion des zweiten Ausführungsbeispiels im Wesentlichen der des ersten Ausführungsbeispiels, so dass sich insoweit eine weitere Beschreibung an dieser Stelle erübrigt.Incidentally, the construction of the second embodiment substantially corresponds to that of the first embodiment, so that in this respect further description is unnecessary at this point.

Alternativ ist es aber auch denkbar, beispielsweise an der Unterseite des Abdeckrostes oder an der entsprechenden Querrippe eine Edelstahlfeder, z. B. durch Eingießen, anzuordnen, die in Richtung auf das erste Rastelement am Grundkörper vorgespannt und mit diesem in Eingriff bringbar ist.Alternatively, it is also conceivable, for example, on the underside of the cover grating or on the corresponding transverse rib a stainless steel spring, for. B. by pouring, to be arranged, which is biased in the direction of the first locking element on the base body and engageable with this.

Wie sich ferner den Figuren 2 und 8 entnehmen lassen, sind an der Unterseite des Deckels 22 bzw. 122 Aussparungen 60 bzw. 160 ausgebildet, in die am Grundkörper 12 entsprechend angeordnete Nasen 62 eingreifen.As can further be seen from FIGS. 2 and 8, recesses 60 and 160 are formed on the underside of the cover 22 and 122, respectively, into which lugs 62 correspondingly arranged on the base body engage.

Bezüglich des ersten Ausführungsbeispiel sind in Figur 2 die Aussparungen 60 und die zugehörigen Nasen 62 gestrichelt dargestellt, während in Figur 5 in perspektivischer Ansicht nur die Nasen 62 erkennbar sind. Im ersten Ausführungsbeispiel sind zwei voneinander beabstandete Nasen 62 auf der Auflagefläche 21 des an der Zarge 19 ausgebildeten Absatzes 20 angeordnet, so dass sich die Nase 62 von der Auflagefläche 21 erheben (vgl. insbesondere Figur 5). Dementsprechend sind im dargestellten Ausführungsbeispiel die zugehörigen Aussparungen 60 an der Unterseite des Umlaufsteges 26 des Deckels 22 ausgebildet. Es ist aber auch denkbar, nur eine Nase 62 am Grundkörper 12 und dementsprechend eine Aussparung 60 am Deckel 22 vorzusehen. Ebenfalls ist es denkbar, mehr als zwei Paare von Aussparungen 60 und Nasen 62 vorzusehen. Gewöhnlich ist an jeder Längsseite des Grundkörpers 12 mindestens eine Nase 62 angeordnet, die in eine zugehörige, an der entsprechenden Längsseite des Deckels 22 ausgebildete Aussparung 60 eingreift.With regard to the first embodiment, the recesses 60 and the associated lugs 62 are shown in dashed lines in Figure 2, while in Figure 5 in a perspective view only the lugs 62 are visible. In the first exemplary embodiment, two spaced-apart lugs 62 are arranged on the bearing surface 21 of the shoulder 20 formed on the frame 19, so that the lugs 62 rise from the bearing surface 21 (cf., in particular, FIG. Accordingly, in the illustrated embodiment, the associated recesses 60 are formed on the underside of the circulating web 26 of the lid 22. But it is also conceivable to provide only a nose 62 on the base body 12 and accordingly a recess 60 on the cover 22. It is also conceivable to provide more than two pairs of recesses 60 and lugs 62. Usually, at least one nose 62 is arranged on each longitudinal side of the base body 12, which engages in an associated, formed on the corresponding longitudinal side of the lid 22 recess 60.

Beim zweiten Ausführungsbeispiel werden an beiden Längsseiten des Abdeckrostes 122 die beiden Aussparungen 160 jeweils von einer Lücke gebildet, die bei Aufliegen des Deckels 122 auf den Grundkörper 12 zwischen einem in Längsrichtung des Abdeckrostes 122 verbreiterten seitlichen Endabschnitt 133 einer mittleren Querrippe 132 und dem seitlichen Endabschnitt 132a der benachbarten Querrippen 132 entsteht. In diese als Aussparung 160 dienenden Lücken greifen die von der Auflagefläche 21 des Grundkörpers 12 emporragenden Nasen 62 (vgl. Figur 5) ein. Dabei ist im dargestellten Ausführungsbeispiel die Breite des verbreiterten seitlichen Endabschnittes 133 in Längsrichtung des Abdeckrostes 122 so bemessen, dass er im Wesentlichen in die zwischen den beiden paarweise angeordneten Nasen 62 gebildete Lücke passt und dadurch beide Nasen 62 im Wesentlichen an diesem verbreiterten seitlichen Endabschnitt 133 anliegen, um eine Arretierung mit möglichst geringer Toleranz zur Erzielung der gewünschten Verschiebesicherung zu bewirken. Alternativ oder zusätzlich ist es aber auch denkbar, die Breite der Aussparungen 160 in Längsrichtung des Abdeckrostes 122 entsprechend der Breite der in sie eingreifenden Nasen 62 zu bemessen.In the second embodiment, the two recesses 160 are each formed on both longitudinal sides of the Abdeckrostes 122 of a gap, which in the cover 122 resting on the base 12 between a widened in the longitudinal direction of the cover grate 122 lateral end portion 133 of a central transverse rib 132 and the lateral end portion 132a the adjacent transverse ribs 132 is formed. In this serving as a recess 160 gaps engage the protruding from the support surface 21 of the body 12 lugs 62 (see Figure 5). In this case, in the illustrated embodiment, the width of the widened lateral end portion 133 in the longitudinal direction of the cover grate 122 is dimensioned so that it fits substantially into the gap formed between the two paired lugs 62 and thereby both lugs 62 substantially abut this widened lateral end portion 133 To effect a lock with the least possible tolerance to achieve the desired displacement protection. Alternatively or additionally, however, it is also conceivable to dimension the width of the recesses 160 in the longitudinal direction of the cover grating 122 in accordance with the width of the lugs 62 engaging in them.

Beim Auflegen des Deckels 22 bzw. 122 auf den Grundkörper 12 findet somit nicht nur ein Eingriff zwischen den ersten und zweiten Rastelementen zur rastenden Verriegelung des Deckels 22 bzw. 122 am Grundkörper 12 statt, sondern greifen zusätzlich die Nasen 62 am Grundkörper 12 in die Aussparungen 60 bzw. 160 an der Unterseite des Deckels 22 bzw. 122 ein. Mit der Anordnung aus Aussparung 60 bzw. 160 und zugehörigen Nase 62 wird demnach eine Verschiebesicherung geschaffen, die den Deckel 22 bzw. 122 gegen unerwünschte Bewegungen in Längsrichtung gegenüber dem Grundkörper 12 fixiert. Solche unerwünschten Verschiebebewegungen können insbesondere dann auftreten, wenn der Deckel 22 bzw. 122 von Fahrzeugen überfahren wird, und dabei zu einer erhöhten Belastung der Verriegelungseinrichtungen 38, 40 bzw. 138, 140 führen. Mit Hilfe der durch die Nasen 62 und die zugehörigen Aussparungen 60 bzw. 160 gebildeten Verschiebesicherung werden dagegen die Verriegelungseinrichtungen 38, 40 bzw. 138, 140 entsprechend entlastet.When placing the cover 22 or 122 on the base body 12 thus takes place not only an engagement between the first and second locking elements for latching locking of the lid 22 and 122 on the base body 12 instead, but additionally engage the lugs 62 on the base body 12 in the recesses 60 and 160 at the bottom of the lid 22 and 122 a. With the arrangement of recess 60 or 160 and associated nose 62 a displacement protection is thus provided, which fixes the lid 22 and 122 against undesired movements in the longitudinal direction relative to the base body 12. Such unwanted displacement movements can occur, in particular, when the cover 22 or 122 is run over by vehicles, thereby leading to increased loading of the locking devices 38, 40 and 138, 140. By contrast, the locking devices 38, 40 and 138, 140 are correspondingly relieved with the help of the anti-slip device formed by the lugs 62 and the associated recesses 60 and 160, respectively.

Die zuvor beschriebene Anordnung von Aussparungen 60 bzw. 160 und Nasen 62 dient im Wesentlichen zur verschiebesicheren Arretierung in Längsrichtung des Abdeckrostes 22 bzw. 122.The arrangement of recesses 60 or 160 and lugs 62 described above essentially serves for the displacement-proof locking in the longitudinal direction of the cover grille 22 or 122.

Für eine verschiebesichere Arretierung in Querrichtung können bei Bedarf weitere Maßnahmen vorgesehen sein. Diese sind beim Abdeckrost 122 gemäß dem zweiten Ausführungsbeispiel in Form von Fortsätzen 164 vorgesehen. Wie Figur 7 erkennen lässt, sind diese Fortsätze 164 an Querrippen 132 angeformt und erstrecken sich nach unten. Es ist alternativ aber auch denkbar, die Fortsätze beispielsweise an einer anderen Stelle an der Unterseite des Abdeckrostes anzuordnen. Die Fortsätze 164 sind so positioniert, dass sie einen Anschlag zur Anlage an den jeweils benachbarten Innenseitenwandabschnitt 19a der Zarge 19 des Grundkörpers 12 bilden, welcher sich unterhalb der Auflagefläche 21 an dieser anschließt (vgl. Figuren 3 und 8). Es ist aber gleichfalls denkbar, dass die als Anschlag dienenden Fortsätze in ihrer Länge so dimensioniert sind, dass sie in Anlage nicht nur an den Innenseitenwandabschnitt 19a der Zarge 19, sondern auch an den sich darunter anschließenden Innenseitenwandabschnitt 17a des Rinnenkörpers 17 bringbar sind.If necessary, further measures can be provided for a shift-proof locking in the transverse direction. These are provided in cover grate 122 according to the second embodiment in the form of extensions 164. Like figure 7, these extensions 164 are integrally formed on transverse ribs 132 and extend downwards. It is alternatively also conceivable to arrange the extensions, for example, at a different location on the underside of the cover grating. The extensions 164 are positioned so that they form a stop for abutment with the respectively adjacent inner side wall section 19a of the frame 19 of the base body 12, which adjoins the support surface 21 below it (compare FIGS. 3 and 8). However, it is also conceivable that the projections serving as a stop in their length are dimensioned so that they can be brought into abutment not only to the inner side wall portion 19a of the frame 19, but also to the subsequent inner side wall portion 17a of the gutter body 17.
