Abstract

The cover component (17) on its opposite second long side has at least one securing component (20) which engages in a corresp. recess (19) of the frame (1). The securing component has two downwardly extending spring arms (21), which are secured in a recess of the frame. The securing component is displaceable in the direction of the springing action of the spring arms and is fixed to the cover component. The spring arms are spaced to the lateral inner surface of the recess of the frame in order to absorb the width tolerances of the frame and cover component. The securing component snap-engages on a holding cam (26) on the second long side, and is made of plastic or metal.

Description

In der EP-A-399 955 ist eine Entwässerungsrinne gemäss Oberbegriff des Anspruchs 1 mit Verschlusselementen zur Sicherung eines Rostes auf einem Rahmen beschrieben. Diese Rinnen haben sich sehr bewährt. Allerdings erfordern die Verschlusselemente die Herstellung von Rost und Rahmen in sehr engen Toleranzen. Diese Teile können daher nur in wenigen spezialisierten Giessereien hergestellt werden oder müssen mechanisch nachbearbeitet werden.EP-A-399 955 describes a drainage channel according to the preamble of claim 1 with closure elements for securing a grate on a frame. These channels have proven their worth. However, the closure elements require the manufacture of grate and frame in very tight tolerances. These parts can therefore only be manufactured in a few specialized foundries or have to be reworked mechanically.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Entwässerungsrinne obiger Art anzugeben, welche geringere Toleranzanforderungen an Rost und Rahmen stellt. Diese Aufgabe wird durch die Merkmalskombination der Ansprüche gelöst.The present invention has for its object to provide a drainage channel of the above type, which places lower tolerance requirements on the grate and frame. This object is achieved by the combination of features of the claims.

Der Rahmen 1, der vorzugsweise aus Guss hergestellt ist, hat zwei gerade Längsstege 2 mit ebenen Seitenflächen 3, welche durch zwei Querstege 4 so verbunden sind, dass die Rahmenbreite a ungefähr der Breite b der Rinne 30 entspricht. Diese Anordnung hat den Vorzug, dass Verbundsteine sauber und lückenlos an einen Rinnenstrang angebaut werden können. Die Querstege 4 sind dort wo diese mit den Längsstegen 2 zusammentreffen mit Kerben 6 ausgestattet. Diese Kerben 6 bilden eine Sollbruchstelle. Diese Ausbildung dient dazu, dass nach erfolgtem Einbau eines solchen Rinnensystems die Querstege 4 auf einfache Weise entfernt werden können, damit der ganze Rinnenstrang offen ist, d.h. der Rinnenstrang hat keine für die Reinigung störende Querverbindungen. Die Längsstege 2 sind im Querschnitt als Doppelwinkel ausgebildet, wobei die oberen vertikalen Stege 7, 8 die äussere Begrenzung sowie die Krone der Abdeckung bilden. Die beiden nach unten ausgerichteten Schenkel 9, 10 sind nach innen versetzt, sodass sie zwischen den Rinneninnenseiten 11 liegen und als Distanzhalter beim Rinneneinbau wirken. Die durch die Doppel-Winkelprofile entstehenden Auflageflächen 12, 13 werden mit der Rinnenkrone vergossen. Die oberen, horizontalen Flächen bilden die Rostauflager 14, 15. An den Rostauflagern 14, 15 sind in der Längsmitte um eine Stegteilung des Rostes 17 gegenseitig versetzte Aussparungen 16 angebracht. Diese dienen zur Kraftübertragung zwischen Rost 17 und Rahmen 1 in Längsrichtung.The frame 1, which is preferably made of cast iron, has two straight longitudinal webs 2 with flat side surfaces 3, which are connected by two transverse webs 4 so that the frame width a corresponds approximately to the width b of the channel 30. This arrangement has the advantage that composite blocks can be neatly and seamlessly attached to a channel run. The transverse webs 4 are provided with notches 6 where they meet with the longitudinal webs 2. These notches 6 form a predetermined breaking point. This design serves to ensure that, after the installation of such a channel system, the crossbars 4 can be removed in a simple manner, so that the entire channel line is open, ie the channel line has no cross-connections that interfere with cleaning. The longitudinal webs 2 are designed in cross section as a double angle, the upper vertical webs 7, 8 forming the outer boundary and the crown of the cover. The two downwardly directed legs 9, 10 are offset inwards so that they lie between the inside of the gutter 11 and act as a spacer when installing the gutter. The contact surfaces 12, 13 created by the double angle profiles are cast with the channel crown. The upper, horizontal surfaces form the grate supports 14, 15. On the grate supports 14, 15, mutually offset recesses 16 are provided in the longitudinal center around a web division of the grate 17. These are used for power transmission between the grate 17 and frame 1 in the longitudinal direction.

Der nach unten gerichtete Schenkel 9 ist auf seiner Länge an zwei Stellen nach der Innenseite verbreitert. Innerhalb dieser Verbreiterung 18 ist eine rechteckige Aussparung 19 ausgespart. Diese Aussparung 19 wird nach oben sowie auch nach unten breiter, wobei der sich nach oben öffnende Teil kürzer ist als derjenige, der sich nach unten aufweitet. Diese Ausbildung der Aussparungen 19 ermöglicht den Einrastelementen 20, welche an entsprechenden Positionen am Rost 17 angebracht und mit je zwei Federschenkeln 21 ausgestattet sind, sich so einzufügen, dass durch Eindrücken des Rostes 17 die beiden Federschenkel 21 zusammengedrückt werden und der Rost 17 bis zum Anschlag am Rostauflager 14 zu liegen kommt. In dieser montierten Position sind die beiden Federschenkel 21 praktisch wieder entspannt und ihre äusseren Flächen 22 schmiegen sich der Aussparung 19 an. Durch die sich nach unten öffnende Konizität der Aussparung 19 sowie die sich formschlüssig anschmiegenden Federschenkel 21 der Einrastelemente 20 entsteht eine Rückhaltekraft, die so gross ist, dass der Rost 17 verkehrssicher zurückgehalten wird.The downward leg 9 is widened in two places along its length on the inside. A rectangular recess 19 is recessed within this widening 18. This recess 19 widens upwards as well as downwards, the part opening upwards being shorter than the part widening downwards. This design of the recesses 19 enables the snap-in elements 20, which Appropriate positions attached to the grate 17 and each equipped with two spring legs 21 to insert so that the two spring legs 21 are pressed together by pressing the grate 17 and the grate 17 comes to rest on the grate support 14 until it stops. In this assembled position, the two spring legs 21 are practically relaxed again and their outer surfaces 22 nestle against the recess 19. Due to the downward tapering of the recess 19 and the form-fitting spring legs 21 of the latching elements 20, a restraining force is created which is so great that the grate 17 is held back safely.

Der gegenüberliegende Längssteg 2 des Rahmens 1 hat am oberen, vertikalen Längssteg 8 zwei Rückhalteflügel 24, welche den eingelegten Rost 17 auf der gegenüberliegenden Seite der Einrastelemente 20 arretieren. Die Rückhalteflügel 24 sind so ausgebildet, dass diese mit entsprechend ausgebildeten Aussparungen 25 am Rost 17 beim Einlegen und Verschliessen des Rostes 17 im Rahmen 1 ähnlich wie ein Gelenk wirken. Durch die gegen das Rahmeninnere offenen Aussparungen 19 sowie die Ausbildung der Rückhalteflügel 24 und der entsprechenden Aussparungen 25 am Rost 17, und weil die Federschenkel 21 etwas Abstand zur seitlichen Innenfläche der Aussparung 19 haben, können die unumgänglichen Gusstoleranzen in Querrichtung zwischen Rost 17 und Rahmen 1 problemlos aufgenommen werden, ohne dass die Funktionstüchtigkeit der Arretierung eingebüsst wird.The opposite longitudinal web 2 of the frame 1 has two retaining wings 24 on the upper, vertical longitudinal web 8, which lock the inserted grate 17 on the opposite side of the latching elements 20. The retaining wings 24 are designed such that they act in a similar manner to a joint when the grate 17 is inserted and closed in the frame 1, with correspondingly designed cutouts 25 on the grate 17. Due to the recesses 19 open towards the inside of the frame and the design of the retaining wings 24 and the corresponding recesses 25 on the grate 17, and because the spring legs 21 have some distance from the inner side surface of the recess 19, the inevitable casting tolerances in the transverse direction between the grate 17 and the frame 1 can be easily recorded without losing the functionality of the locking device.

Die Federschenkel 21 der Einrastelemente 20, welche am Rost 17 befestigt sind, stehen beim uneingebauten Rost 17 ungeschützt nach unten ab. Durch die in Längsrichtung des Rahmens 1 versetzte Anordnung der Aussparungen 19 und der Rückhalteflügel 24 steht der Rost 17 bei versehentlich verkehrter Montage auf den Rückhalteflügeln 24 auf, sodass die Federschenkel 21 nirgends aufstehen und daher nicht beschädigt werden.The spring legs 21 of the latching elements 20, which are fastened to the grate 17, are unprotected when the grate 17 is not installed downwards. Due to the staggered arrangement of the recesses 19 and the retaining wings 24 in the longitudinal direction of the frame, the grate 17 stands on the retaining wings 24 in the event of inadvertently incorrect mounting, so that the spring legs 21 do not stand up anywhere and are therefore not damaged.

Die Aussparungen 16, 19 sowie die Rückhalteflügel 24 sind konstruktiv so ausgebildet und angeordnet, dass der Rahmen 1 ohne Einsatz von Kernen gegossen werden kann. Somit können die Teile auf wirtschaftliche Art und Weise hergestellt werden.The recesses 16, 19 and the retaining wings 24 are constructed and arranged in such a way that the frame 1 can be cast without the use of cores. This enables the parts to be manufactured in an economical manner.

Die Gusstoleranzen in Längsrichtung können ebenfalls ohne Beschränkung der Funktionstüchtigkeit des Verschlusses aufgenommen werden, indem die Haltenocken 26 zur Befestigung der Einrastelemente 20 am Rost 17 länger ausgebildet sind als die Breite c der Einrastelemente 20, und dass ebenfalls die Breite d der Aussparungen 25 grösser ist als die Breite e der Rückhalteflügel 24.The casting tolerances in the longitudinal direction can also be accommodated without restricting the functionality of the closure, in that the retaining cams 26 for fastening the latching elements 20 to the grate 17 are longer than the width c of the latching elements 20 and that the width d of the cutouts 25 is also greater than the width e of the retaining wings 24.

Die beiden mittleren Stege 27 des Rostes 17 sind auf ihrer Unterseite so ausgebildet und nach aussen verlängert, dass diese Verlängerung 28 in die Aussparung 16 vom Rostauflager 14, 15 so eingreift, dass die Längskräfte vom Rost 17 auf den Rahmen 1 übertragen werden können. Die Kraftübertragung vom Rahmen 1 auf die Rinne 30, welche z.B. aus Polyesterbeton gefertigt ist, wird mit der bekannten "Monoguss-Verbindung" gelöst, oder allenfalls durch eine äussere Verzahnung des Rahmens 1, welche direkt ins Betonfundament eingreift, welches die Rinne stützt.The two middle webs 27 of the grate 17 are designed on their underside and extended outwards so that this extension 28 engages in the recess 16 from the grate support 14, 15 such that the longitudinal forces can be transmitted from the grate 17 to the frame 1. The power transmission from the frame 1 to the channel 30, which is made of polyester concrete, for example, is solved with the known "mono-cast connection", or at most by an external toothing of the frame 1, which engages directly in the concrete foundation that supports the channel.

Bei Anwendungen, bei welchen aus bestimmten Gründen auf die Verbindung zwischen Rahmen 1 und Rinne 30 verzichtet werden muss, ist in der Mitte der beiden mittleren Stege 27 eine halbmondförmige Vertiefung 29 angebracht. Diese Vertiefung 29 ermöglicht es, mit einer bekannten Arretierung die Gussgarnitur 31 als Ganzes mittels nur einer Schraube mit der Rinne 30 zu verbinden. Der eigentliche Verschluss wird durch die Einrastelemente 20 gebildet, welche am Rost 17 vormontiert sind und somit diesen mit den beiden Federschenkeln 21 der Einrastelemente 20 am Rahmen 1 festhalten.In applications in which for certain reasons the connection between frame 1 and channel 30 has to be dispensed with, a crescent-shaped depression 29 is provided in the middle of the two central webs 27. This recess 29 makes it possible, with a known locking device, to connect the cast fitting 31 as a whole to the channel 30 by means of only one screw. The actual closure is formed by the snap-in elements 20, which are preassembled on the grate 17 and thus hold it on the frame 1 with the two spring legs 21 of the snap-in elements 20.

Die Vormontage der Einrastelemente 20 erfolgt auf einfache Weise. Die Oeffnung 32 der Einrastelemente 20, welche nach aussen weiter wird und am Ende einen oberen und unteren Rückhaltenocken 33, 34 aufweist, wird über die am Rost 17 ausgebildeten Haltenocken 26 gedrückt. Dadurch wird die Oeffnung 32 durch die beiden Rückhaltenocken 33, 34 aufgedehnt, bis diese an den Rückhaltenuten 35, 36 einrasten. Die Einrastelemente 20 sind somit annähernd formschlüssig mit dem Rost 17 verbunden. Bei im Rahmen montierten Rost 17 können die Einrastelemente 20 nicht vom Rost 17 demontiert werden. Sie werden durch den oberen, vertikalen Längssteg 7 zurückgehalten. Somit können die Einrastelemente 20 durch äussere Einflüsse im montierten Zustand nicht entfernt oder abgedrückt werden.The pre-assembly of the snap-in elements 20 is carried out in a simple manner. The opening 32 of the latching elements 20, which widens outwards and has an upper and lower retaining cams 33, 34 at the end, is pressed over the retaining cams 26 formed on the grate 17. As a result, the opening 32 is expanded by the two retaining cams 33, 34 until they snap into the retaining grooves 35, 36. The latching elements 20 are thus connected to the grate 17 in an approximately form-fitting manner. When the grate 17 is mounted in the frame, the latching elements 20 cannot be removed from the grate 17. They are held back by the upper, vertical longitudinal web 7. Thus, the snap-in elements 20 cannot be removed or pulled off by external influences in the assembled state.

In Figur 8 ist ein Querschnitt durch eine andere Variante des Rahmens 1' dargestellt, bei welcher die Längsstege 2 des Rahmens 1' als T-Profile 38 ausgebildet sind, wobei seitliche Stützen 39 aussen an der Rinnenwand 37 heruntergezogen sind.FIG. 8 shows a cross section through another variant of the frame 1 ', in which the longitudinal webs 2 of the frame 1' are designed as T-profiles 38, lateral supports 39 being pulled down on the outside of the channel wall 37.

Diese seitlichen Stützen 39 können beispielsweise eine Verzahnung aufweisen, um den Rahmen 1' im Betonfundament zu verankern.These side supports 39 can have teeth, for example, in order to anchor the frame 1 'in the concrete foundation.

Die beschriebene Verbindung der Querstege 4 mit den Längsstegen 2 des Rahmens 1 kann mit dem gleichen Vorteil auch bei anderen Entwässerungsrinnen, z.B. jenen nach EP-A-399 955 oder Rinnen, bei welchen der Rost nicht gegen ein Herausspringen gesichert ist, eingesetzt werden.The described connection of the crossbars 4 to the longitudinal webs 2 of the frame 1 can also be used with other drainage channels, e.g. those according to EP-A-399 955 or channels in which the grate is not secured against jumping out can be used.

Alternativ zur beschriebenen Ausführung können die Einrastelemente 20 auch aus Metall, z.B. aus nichtrostendem Federstahlblech ausgebildet werden. Diese Ausführungsform ist in Fig. 9 perspektivisch dargestellt.As an alternative to the embodiment described, the latching elements 20 can also be made of metal, e.g. made of stainless spring steel sheet. This embodiment is shown in perspective in FIG. 9.
