Abstract
Description
Die- Erfindung richtet sich auf eine Vorrichtung aus einem verriegelbaren Abdeckrost und einer Entwässerungs- bzw. Drainagerinne der im Oberbegriff des Anspruches 1 angegebenen Gattung, wie sie aus der DE-195 45 131-A bekannt ist.The invention is directed to a device comprising a lockable cover grate and a drainage or drainage channel of the type specified in the preamble of claim 1, as known from DE-195 45 131-A.
Etwas andere Verriegelungsmöglichkeiten von Rinnenabdeckungen sind beispielsweise aus der DE-195 45 131-A, der DE-44 47 121-A oder der DE-43 40 410-A bekannt, wobei es auch bekannt ist, die Drainagerinnen mit oberrandseitigen, verstärkenden Abdeckprofilen, insbesondere aus Metall, auszurüsten. Diese Profile dienen nicht nur zur Verstärkung der oberen Randkante, sondern gleichzeitig als Auflage für die Abdeckroste. Dabei ist es bekannt, diese Roste an den Profilen z.B. durch Hakenelemente zu befestigen, wie dies beispielsweise die WO 01/94709-A1 der Anmelderin zeigt.Slightly different locking possibilities of gutter covers are known, for example, from DE-195 45 131-A, DE-44 47 121-A or DE-43 40 410-A, wherein it is also known to use the drainage gutters with upper-edge reinforcing cover profiles. especially of metal, equip. These profiles serve not only to reinforce the upper edge, but also as a support for the grids. It is known, these grates on the profiles, e.g. fasten by hook elements, as shown for example in WO 01/94709-A1 of the Applicant.
Eine andere Befestigung z.B. über einen Stift zeigt die WO 00/14340-A1, eine von einer zentralen Spannschraube beaufschlagte flügelartige Befestigung, die in Ausnehmungen in der Rinne von unten eingreift, zeigt die EP-0 248 427-A2, wobei die DE-195 11 788-C1 eine ähnliche Lösung zeigt. Ein aus einem Federmetall gebogenes Sperrelement zeigt die DE-42 41 703 sowie die DE-42 41 705-A1.Another attachment, eg via a pin, is shown in WO 00/14340-A1, a wing-like attachment acted on by a central tensioning screw, which engages in recesses in the channel from below, is shown in EP-0 248 427-A2, DE-195 11 788-C1 shows a similar solution. A bent from a spring metal blocking element shows the DE-42 41 703 and DE-42 41 705-A1.
Den oben genannten Lösungen ist gemein, daß sie zum Teil vergleichsweise aufwendig gestaltet sind und/oder in der Handhabung beschwerlich oder nur mit Werkzeugen betätigbar sind.The above-mentioned solutions have in common that they are designed in part comparatively expensive and / or difficult to handle or can only be operated with tools.
Dem abzuhelfen ist Aufgabe der Erfindung, die darin besteht, einen einfachen sicheren und im wesentlichen wartungsfreien verriegelungsverschluß für Abdeckroste bereitzustellen.To remedy this is the object of the invention, which is to provide a simple safe and essentially maintenance-free locking closure for cover gratings.
Diese Aufgabe wird mit einer Vorrichtung der eingangs bezeichneten Art dadurch gelöst, daß am Abdeckrost an jeder Längsseite wenigstens ein Zapfen oder Steg angeformt ist und daß die Blattfeder schmaler als die Breite des Zapfens oder Steges ausgebildet ist, wobei der Zapfen eine Aufnahmenut aufweist, in die die Blattfeder eingeklemmt ist.This object is achieved with a device of the type described above in that the cover grating on each longitudinal side at least one pin or web is formed and that the leaf spring is formed narrower than the width of the pin or web, wherein the pin has a receiving groove in the the leaf spring is clamped.
Mit der Erfindung wird mit einfachen Mitteln erreicht, daß der Rost sicher an den Drainagerinnen festgelegt werden kann, wobei sowohl die Montage wie auch die Demontage ohne größeren Aufwand und ohne besondere Werkzeuge möglich ist.With the invention is achieved by simple means that the rust can be securely fixed to the drainage, both assembly and disassembly without much effort and without special tools is possible.
Darüber hinaus wird auch ein Auseinandertreiben der seitlichen Rinnenschenkel durch die Verrastung des Rostes verhindert.In addition, a disintegration of the lateral gutter legs is prevented by the locking of the grate.
Auch wird durch diese Gestaltung erreicht, daß die Blattfeder immer fest am Zapfen fixiert ist, d.h. insbesondere bei Abheben des Abdeckrostes nicht verrutscht, zum anderen ist durch diese Art der Befestigung gewährleistet, daß die Blattfeder weitestgehend von Schmutzbefall befreit ist, da evtl. einfallende Schmutzpartikel an der Blattfeder nach unten fallen können.It is also achieved by this design that the leaf spring is always firmly fixed to the pin, i. especially when lifting the cover grate does not slip, on the other hand is ensured by this type of attachment that the leaf spring is largely freed from dirt, since any incident dirt particles on the leaf spring may fall down.
Weitere Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen, wobei es vorteilhaft ist, wenn die Blattfeder die freie Unterkante der Nut des Zapfens klemmend umgreift, aus der Nut herausragend mit einer Rastschulter versehen geformt ist und an ihrem oberen freien Ende zwei angeformte Stegnocken in der Nut des Zapfens klemmend untergreift, wobei das äußere freie Ende in Richtung des Zapfens umgeformt ausgebildet ist.Further embodiments of the invention will become apparent from the dependent claims, wherein it is advantageous if the leaf spring, the free lower edge of the groove of the pin clampingly surrounds, is provided protruding from the groove provided with a locking shoulder and at its upper free end two molded Stegnocken in the groove the pin engages under clamping, wherein the outer free end is formed formed in the direction of the pin.
Durch diese Art der Federgestaltung ist auch deren Montage sehr einfach möglich, die Blattfeder wird mit ihrem unteren freien umgebogenen Ende über den entsprechenden Bereich desBy this type of spring design and their installation is very easy, the leaf spring is with its lower free bent end over the corresponding area of
Nockens geschoben und mit ihrem oberen Ende über die Stegnocken in die Nut des Zapfens gedrückt, so daß die Feder hier entsprechend einrastet.Cam pushed and pressed with its upper end on the Stegnocken in the groove of the pin, so that the spring snaps into place accordingly.
Eine weitere Ausgestaltung der Erfindung besteht darin, daß die Größe der Eingriffsöffnung im Randprofil der Rinne in Längsrichtung geringfügig größer ist als die entsprechende Ausdehnung der nischenförmigen Ausnehmung im Rinnenmaterial, derart, daß bei Verschieben des Rostes die auftretenden Kräfte in das Rinnenmaterial und nicht in das Kopfprofil einleitbar sind.A further embodiment of the invention is that the size of the engagement opening in the edge profile of the channel in the longitudinal direction is slightly larger than the corresponding extent of the niche-shaped recess in the channel material, such that upon displacement of the grate, the forces occurring in the channel material and not in the head profile can be introduced.
Es hat sich gezeigt, daß diese Bemessung besonders zweckmäßig ist, um auch bei Querkräften, die ggf. auf dem Rost ausgeübt werden, die Festigkeit der Rinne zu gewährleisten und Brüchen vorzubeugen.It has been shown that this design is particularly useful in order to ensure the strength of the channel and to prevent fractures even with lateral forces that may be exerted on the grate.

In den Fig. 1 bis 4 ist die mit 1 bezeichnete Vorrichtung zum Verriegeln eines nur teilweise wiedergegebenen gußeisernen Abdeckrostes 2 dargestellt, der auf die Oberrandkante einer wiederum nur im Ausschnitt dargestellten, querschnittlich im wesentlichen U-förmigen Drainagerinne 3 aufgelegt ist.In Figs. 1 to 4, the device designated 1 for locking a partially reproduced cast-
Die Vorrichtung 1 dient zum Verriegeln des Abdeckrostes 2 an der Drainagerinne 3. Diese Drainagerinne 3 weist, wie bekannt, an ihrer freien oberen Randkante jeweils ein querschnittlich etwa h-förmiges längsverlaufendes Kopfprofil 4 auf, welches aus Metall besteht und über die obere freie Randkante 5 der Drainagerinne 3 geclipst ist, worauf es hier nicht näher ankommt.This
Wie sich insbesondere aus Fig. 1 und 2 ergibt, weist der Abdeckrost 2 einen einstückig angeformten, nach unten ragenden, in Fig. 2 im Schnitt dargestellten Zapfen 6 auf, wobei jeder Rost 2 mit wenigstens zwei derartigen Zapfen 6 etwa in seiner Mitte ausgerüstet sein kann, es können aber auch mehr als zwei derartige Zapfen vorgesehen sein. Diese Zapfen 6 weisen etwa mittig zur Innenseite hin ausgebildet eine Nut 7 auf, derart, daß sich zwei obere außenrandseitige Stegnocken 8 ausbilden, wobei das untere freie Ende des Nockens 6 mit einem weiteren kleinen nutförmigen Rücksprung 9 ausgerüstet ist.As can be seen in particular from FIGS. 1 and 2, the
Dieser Rücksprung 9 wird von einem gekrümmten Teil 10a einer Metallblattfeder 10 umgriffen, die am anderen freien Ende einen weiteren gekrümmten Bereich 10b aufweist sowie außenrandseitige Klemmbereiche 10c, die auf dem Rand der Feder angestanzt sind und so geformt sind, daß sie die Stegnocken 8 zu untergreifen in der Lage sind, derart, daß die Blattfeder 10 fest am Nocken 6 fixiert ist.This
Das das freie Ende der Drainagerinne 3 übergreifende metallische Randkantenprofil 4 weist eine Ausstanzung 11 als Eingriffsöffnung auf, die etwas größer ist als die Breite des Zapfens 6, wie sich dies insbesondere aus Fig. 4 ergibt. In diese Ausstanzung 11 kann der Zapfen 6 mit der aufgeclipsten Blattfeder 10 eingreifen, insbesondere da in diesen Bereich auch die zugeordnete Wand der Drainagerinne 3 je eine entsprechende Ausnehmung 12 aufweist. Nach Verrastung der Zapfen 6 wird sicher ein Auseinandertreiben der Randkanten- bzw. Kopfprofile 4 und damit der Rinnenschenkel verhindert.The free edge of the
Wie sich insbesondere aus Fig. 2 ergibt, ist die Blattfeder 10 mit einer nockenförmigen Wölbung 10d ausgerüstet, die sich klemmend hinter den entsprechenden Bereich 4a des Abdeckprofiles 4 legt, auch dies ist aus Fig. 2 ersichtlich.As can be seen in particular from FIG. 2, the
In den Fig. 5 bis 8 tragen alle die baugleichen Teile, insbesondere des Rinnenkörpers, die identischen Bezugszeichen wie nach den Fig. 1 bis 4. Anders als dort dargestellt, handelt es sich hier nicht um einen gußeisernern Abdeckrost, sondern um ein Abdeckrost 3a aus Metallblech.5 to 8 carry all the identical parts, in particular the gutter body, the identical reference numerals as shown in FIGS. 1 to 4. Contrary to what is shown here, this is not a Gußeisernern cover grate, but a cover grid 3a Metal sheet.
Der beim Ausführungsbeispiel der Fig. 1 bis 4 dargestellte angegossene Zapfen 6 wird hier von einem nach unten weisenden Metallsteg 13 gebildet, an dem mittels einer Niet 14 eine allgemein mit 15 bezeichnete Blattfeder befestigt ist in vergleichbarer Faltung der Blattfeder 10. Die Blattfeder 10 ist jedoch nicht in eines Aufnahmennt des Zapfens 13 geführt.
Auch hier umgreift ein gekrümmter Teil 15a das untere freie Ende des Steges 13, wobei auch hier eine Klemmschulter 15d ausgebildet ist.The molded
Here, too, a curved part 15a surrounds the lower free end of the
Die Wirkung bzw. Funktionsweise ist hier die gleiche wie bei der Ausführungsform nach den vorangegangenen Fig. 1 bis 4, die entsprechende Beschreibung gilt hier in gleicher Weise.The effect or functioning here is the same as in the embodiment according to the preceding FIGS. 1 to 4, the corresponding description applies here in the same way.
Natürlich ist das beschriebene Ausführungsbeispiel der Erfindung noch in vielfacher Hinsicht abzuändern, ohne den Grundgedanken zu verlassen. So kann, wie weiter oben schon ausgeführt, pro Abdeckrost ein Paar oder mehrere Paare von Nocken bzw. Stegen 6 mit Blattfedern 10 bzw. 13 vorgesehen sein, die Roste können als Gitterroste, als Kunststoffroste oder bevorzugt als gußeiserne Roste ausgebildet sein. Das Randkantenprofil 4 kann auch als einfaches Winkelprofil ausgebildet sein oder eine andere Profilform aufweisen, wobei die Eingriffsöffnung 11 jede Form aufweisen kann, z.B. auch als Rundbohrung u. dgl. mehr.Of course, the described embodiment of the invention is still to be modified in many ways, without departing from the spirit. Thus, as already stated above, per cover grate a pair or more pairs of cams or
