Description

Die Erfindung betrifft eine Kombination einer Entwässerungsrinne mit einer Abdeckung nach dem Oberbegriff des Patentanspruches 1.The invention relates to a combination of a drainage channel with a cover according to the preamble of patent claim 1.

Entwässerungsrinnen zur Entwässerung von Oberflächen sind vielfach bekannt.Drainage channels for draining surfaces are widely known.

Die Abdeckungen derartiger Entwässerungsrinnen müssen im Allgemeinen überfahrbar sein, wobei die hier auftretenden Lasten sehr unterschiedlich sind. In manchen Fällen sind die Geschwindigkeiten, mit welchen Fahrzeuge die Entwässerungsrinnen bzw. deren Abdeckungen überrollen, sehr hoch, was dazu führt, dass die Abdeckungen mit stoßförmigen Impulsen belastet werden. Diese impulsförmigen Belastungen führen dazu, dass die Abdeckungen sich bewegen, sozusagen "atmen", wobei das Ein- und Ausfedern durch verschiedenartige Kräfte, nämlich einerseits die Belastungskräfte und andererseits die dem Material bzw. dem Aufbau und der Konstruktion innewohnenden Federkräfte diese Bewegungen bestimmen. Diese Bewegungen wiederum führen dazu, dass einerseits ein nicht unerheblicher Verschleiß auftritt, andererseits auch eine Lärmbelästigung festzustellen ist.The covers of such drainage channels must generally be able to be driven over, whereby the loads occurring here are very different. In some cases, the speeds at which vehicles roll over the drainage channels or their covers are very high, which means that the covers are subjected to sudden impulses. These impulse loads cause the covers to move, "breathe" so to speak, with the compression and rebound being determined by various forces, namely the loading forces on the one hand and the spring forces inherent in the material or the structure and construction on the other. These movements in turn lead to not inconsiderable wear and tear, on the one hand, and noise pollution, on the other hand.

An sich könnte man diese Bewegungen dadurch unterbinden, dass man die Abdeckungen mit den Rinnen an beiden Enden jeweils verschraubt. Dies ist sowohl von der notwendigen Konstruktion her als auch von den Montageabläufen ausgesprochen aufwändig. Darum werden vielfach einfachere Verriegelungen, z.B. relativ einfache Schnappverschlüsse gewählt, die dann aber die oben genannten Nachteile zumindest dann mit sich bringen, wenn die Anordnungen einfach und kostengünstig ausgeführt sind, wie dies beispielsweise in der DE 20 2004 000 899 U1 , der DE 88 10 154 U1 oder der DE 27 27 790 A1 gezeigt ist.In principle, these movements could be prevented by screwing the covers to the channels at both ends. This is expressed both by the necessary construction and by the assembly processes laborious. That is why simpler locks, for example relatively simple snap locks, are often chosen, but they then bring the disadvantages mentioned above at least with them if the arrangements are made simple and inexpensive, as is the case, for example, in DE 20 2004 000 899 U1 , the DE 88 10 154 U1 or the DE 27 27 790 A1 is shown.

Aus EP 0 248 427 A2 ist eine Kombination gemäß der Präambel von Anspruch 1 einer Entwässerungsrinne mit einer Abdeckung mit spreizbaren Riegelarmen bekannt, die mit Widerlageflächen zusammenwirken.Out of EP 0 248 427 A2 a combination according to the preamble of claim 1 of a drainage channel with a cover with expandable locking arms which cooperate with abutment surfaces is known.

In EP 0 758 038 A1 und EP 2 468 969 A2 sind Entwässerungsrinnen beschreiben, deren Abdeckungen Rastelemente und Gelenke aufweisen.In EP 0 758 038 A1 and EP 2 468 969 A2 describe drainage channels whose covers have locking elements and joints.

Der Erfindung liegt die Aufgabe zu Grunde, eine Entwässerungsrinne der eingangs genannten Art dahingehend aufzuzeigen, dass mit geringem Konstruktions- und Montageaufwand eine erhöhte Stabilität insbesondere bei dynamischen Belastungen erzielbar ist.The invention is based on the object of demonstrating a drainage channel of the type mentioned at the outset in such a way that increased stability can be achieved with little construction and assembly effort, particularly under dynamic loads.

Diese Aufgabe wird durch eine Kombination einer Entwässerungsrinne mit einer Abdeckung nach Patentanspruch 1 gelöst.This object is achieved by a combination of a drainage channel with a cover according to patent claim 1.

Insbesondere wird diese Aufgabe durch eine Kombination einer Entwässerungsrinne mit einer Abdeckung mit einer Abdeckung und mit zwei Enden, an denen weitere Entwässerungsrinnen anschließbar sind, umfassend Verriegelungseinrichtungen, die eine zum Abheben der Abdeckung lösbare Verbindung zwischen der Abdeckung und der Entwässerungsrinne sicherstellen, dadurch gelöst, dass die Abdeckung zusätzlich zu den Verriegelungseinrichtungen im Bereich der Enden Klemmeinrichtungen aufweist, zur Sicherstellung einer reibschlüssigen Verbindung zwischen der Abdeckung und der Entwässerungsrinne, wobei die Verriegelungseinrichtungen in Längsrichtung der Abdeckung zwischen den Klemmeinrichtungen angebracht sind.In particular, this object is achieved by a combination of a drainage channel with a cover with a cover and with two ends to which further drainage channels can be connected, including locking devices that ensure a detachable connection between the cover and the drainage channel to lift the cover, in that the cover, in addition to the locking devices, has clamping devices in the region of the ends to ensure a frictional connection between the cover and the drainage channel, the locking devices being fitted between the clamping devices in the longitudinal direction of the cover.

Dadurch, dass reibschlüssige Verbindungen (und nicht etwa formschlüssige Schraubverbindungen) vorgesehen werden, ist einerseits der Konstruktionsaufwand relativ gering, andererseits aber konnte überraschenderweise gezeigt werden, dass derartige reibschlüssige Verbindungen das oben beschriebene "Atmen" der Abdeckungen auf den Entwässerungsrinnen zu einem erheblichen Anteil unterbinden.Because frictional connections (and not form-fitting screw connections) are provided, on the one hand the design effort is relatively low, but on the other hand it was surprisingly shown that such frictional connections prevent the above-described "breathing" of the covers on the drainage channels to a considerable extent.

Die Klemmeinrichtungen sind vorzugsweise im Bereich der Enden der Abdeckung vorgesehen und zwar nicht weiter als etwa ein Viertel der Gesamtlänge der Abdeckung von den Enden entfernt. Dadurch, dass in eben diesem kritischen Bereich die Klemmeinrichtungen vorgesehen sind, wird die Bewegung der Abdeckung auf der Entwässerungsrinne bei einem Überfahren besonders wirksam gedämpft.The clamping means are preferably provided in the region of the ends of the cover and no further than about one quarter of the total length of the cover from the ends. Because the clamping devices are provided in precisely this critical area, the movement of the cover on the drainage channel is particularly effectively dampened when the cover is driven over.

Die Klemmeinrichtungen sind im Bereich der Enden vorzugsweise jeweils paarweise einander gegenüberliegend, also symmetrisch angeordnet. Dadurch ergibt sich eine wirksame Verhinderung der genannten Bewegungen.In the region of the ends, the clamping devices are preferably arranged in pairs opposite one another, that is to say symmetrically. This results in an effective prevention of the movements mentioned.

Diese Klemmeinrichtungen können in vielfältiger Form ausgebildet sein. Vorzugsweise weisen sie Vorsprünge auf, welche mit oberen und unteren Schrägflächen ausgebildet sind. Mit dieser Gestaltung ist eine einfache Herstellbarkeit bei gleichzeitig guter Montier- und Demontierbarkeit der Abdeckungen sichergestellt. Insbesondere sollen die unteren Schrägflächen einen derart flacheren Anstiegswinkel als die oberen Schrägflächen haben, dass ein Aufsetzen der Abdeckung auf die Entwässerungsrinne mit einer geringeren Kraft durchführbar ist als ein Abnehmen. Dies erleichtert die Montage und verstärkt die dämpfende Wirkung der Klemmeinrichtungen. Darüber hinaus wird die Abdeckung bei Vibration fester auf die Entwässerungsrinne aufgedrückt.These clamping devices can be designed in many different forms. Preferably, they have projections formed with upper and lower bevels. This design ensures that the covers are easy to produce while at the same time being easy to assemble and disassemble. In particular, the lower sloping surfaces should have such a flatter angle of rise than the upper sloping surfaces that the cover can be placed on the drainage channel with less force than it can be removed. This facilitates assembly and increases the damping effect of the clamping devices. In addition, the cover is pressed more firmly onto the drainage channel during vibration.

Die Verriegelungseinrichtungen können in vielfältiger Form ausgebildet sein. Besonders einfach wird die Herstellung der Anordnung dann, wenn die Klemmeinrichtungen im Wesentlichen identisch wie die Verriegelungseinrichtungen ausgebildet sind. Wenn also die Klemmeinrichtungen - wie oben angedeutet - Vorsprünge mit Schrägflächen aufweisen, so kann die Entwässerungsrinne Hinterschneidungen aufweisen, hinter welche die oberen Schrägflächen der Klemmeinrichtungen einschnappen.The locking devices can be designed in many different forms. The manufacture of the arrangement becomes particularly simple when the clamping devices are configured essentially identically to the locking devices. So if the clamping devices - as indicated above - have projections with inclined surfaces, the drainage channel can have undercuts behind which the upper inclined surfaces of the clamping devices snap.

Besonders einfach ist die Abdeckung als Kunststoff-Spritzgussteil ausführbar.The cover can be implemented particularly easily as a plastic injection molded part.

Wie aus Fig. 1 hervorgeht, umfasst die hier gezeigte Ausführungsform der Erfindung eine Abdeckung 10, die ein erstes Ende 11 und ein zweites Ende 12 aufweist und Schlitze 13 zum Einlassen von Oberflächenwasser umfasst, die durch Stege 14 getrennt sind, welche mit Seitenauflagen 15, 15' in Verbindung stehen. Aus den Querschnittsdarstellungen gemäß den Fig. 2-4 geht hervor, dass die Abdeckung 10 auf einer Rinne 1 aufsitzt, deren erstes Ende 2 mit dem ersten Ende 11 der Abdeckung und deren zweites Ende 3 mit dem zweiten Ende 12 der Abdeckung fluchtet. Die Rinne 1 weist Seitenwände 4, 4' auf, auf deren Oberende die Abdeckung 10 mit ihren Seitenauflagen 15, 15' aufliegt.How out 1 The embodiment of the invention shown here comprises a cover 10 having a first end 11 and a second end 12 and comprising slots 13 for admitting surface water separated by webs 14 communicating with side supports 15, 15' . From the cross-sectional views according to the Figures 2-4 shows that the cover 10 is seated on a channel 1, the first end 2 of which is flush with the first end 11 of the cover and the second end 3 of which is flush with the second end 12 of the cover. The channel 1 has side walls 4, 4', on the upper end of which the cover 10 rests with its side supports 15, 15'.

An den Seitenauflagen 15, 15' nach unten ragend sind Längsstege 16 angeordnet (siehe Fig. 5 und 6), die in die Rinne 1 hineinragen. An diesen Längsstegen 16 sind beidseitig jeweils nach außen hervorragend Klemmeinrichtungen 30 vorgesehen, die jeweils einen Vorsprung 31 umfassen, der eine obere Schrägfläche 32 und eine untere Schrägfläche 33 umfasst. In Längsrichtung der Abdeckung 10 gesehen weisen die Längsstege 16 Wellenabschnitte 34, 34' vor und nach dem Vorsprung 31 auf, so dass die Längsstege 16 im Bereich der Klemmeinrichtung bzw. des Vorsprungs 31 eine gegenüber seitlichen Kräften (quer zur Längsrichtung) erhöhte Elastizität haben.Longitudinal webs 16 are arranged on the side supports 15, 15' and project downwards (see Figures 5 and 6 ) that protrude into channel 1. Clamping devices 30 are provided on both sides of these longitudinal webs 16 , each projecting outwards and each comprising a projection 31 which comprises an upper inclined surface 32 and a lower inclined surface 33 . Viewed in the longitudinal direction of the cover 10, the longitudinal webs 16 have corrugated sections 34, 34′ before and after the projection 31, so that the longitudinal webs 16 in the area of the clamping device or the projection 31 have increased elasticity compared to lateral forces (transverse to the longitudinal direction).

Bei der hier gezeigten Ausführungsform sind in der Nähe der Enden 11, 12 der Abdeckung 10 die Seitenwände 4, 4' der Rinne 1 glatt ausgeführt, so dass bei einem Aufsetzen der Abdeckung 10 auf die Rinne 1 die Vorsprünge 31 unter Verformung der Wellenabschnitte 34, 34' nach innen gedrückt werden und mit den Seitenwänden 4, 4' der Rinne 1 in reibschlüssigem Kontakt stehen.In the embodiment shown here, the side walls 4, 4' of the channel 1 are smooth in the vicinity of the ends 11, 12 of the cover 10, so that when the cover 10 is placed on the channel 1, the projections 31 deform the shaft sections 34, 34' are pressed inwards and are in frictional contact with the side walls 4, 4' of the channel 1.

In der Mitte der Abdeckung 10 sind identisch ausgeführte Klemmeinrichtungen 30 mit Vorsprüngen 31 vorgesehen, jedoch weist die Rinne 1 Ausnehmungen auf, die Hinterschneidungen 5, 5' (siehe Fig. 3) bilden. Beim Aufsetzen der Abdeckung 10 auf die Rinne 1 schnappen somit die Vorsprünge 31 der Klemmeinrichtung 30 in diese Hinterschneidungen 5, 5' ein und bilden somit eine Verriegelung. Dadurch, dass die oberen Schrägflächen 32 der Vorsprünge 31 steiler ausgebildet sind als die unteren Schrägflächen 33 wird einerseits das Aufsetzen einer Abdeckung 10 auf die Rinne 1 erleichtert, andererseits wirken im Falle der mittig angebrachten Verriegelungseinrichtungen 20 diese steileren oberen Schrägflächen 32 als kräftiger Halt in den Hinterschneidungen 5, 5'. Im Bereich der Enden 11, 12 der Abdeckung 10 wirkt diese asymmetrische Ausbildung der Schrägflächen 32, 33 im Sinne einer erhöhten Reibungskraft beim Abheben der Abdeckung 10 von der Rinne 1 gegenüber einem Aufsetzen. Dadurch wird gewährleistet, dass bei dynamischen Bewegungen der Abdeckung 10 auf der Rinne 1 z.B. durch ein Übergehen oder ein Überfahren eine (über die Zeit betrachtet) summenresultierende Kraft nach unten wirkt, welche bei Vibrationen die Abdeckung 10 fester auf die Rinne 1 aufdrückt.In the middle of the cover 10 identically designed clamping devices 30 with projections 31 are provided, but the channel 1 has recesses, the undercuts 5, 5' (see 3 ) form. When the cover 10 is placed on the channel 1, the projections 31 of the clamping device 30 snap into these undercuts 5, 5' and thus form a lock. The fact that the upper inclined surfaces 32 of the projections 31 are steeper than the lower inclined surfaces 33 makes it easier to place a cover 10 on the channel 1, on the one hand, and on the other hand, in the case of the centrally mounted locking devices 20, these steeper upper inclined surfaces 32 act as a strong hold in the Undercuts 5, 5'. In the area of the ends 11, 12 of the cover 10, this asymmetrical design of the inclined surfaces 32, 33 acts in the sense of an increased frictional force when the cover 10 is lifted off the channel 1 compared to touching it down. This ensures that during dynamic movements of the cover 10 on the channel 1, for example by walking over or driving over it, a total resulting force (viewed over time) acts downwards, which presses the cover 10 more firmly onto the channel 1 in the event of vibrations.
