Description

Die Erfindung betrifft eine Entwässererungsrinne mit Sicherungseinrichtung und Adbdeckwost gemäß dem Oberbegriff der Patentansprüche 1 oder 2.The invention relates to a drainage channel with safety device and Adbdeckwost according to the preamble of the claims 1 or 2.

Eine Sicherungseinrichtung für eine Entwässerungsrinne ist beispielsweise aus der DE 42 41 707 A1 bekannt.A safety device for a drainage channel is known for example from DE 42 41 707 A1.

Bei der dort gezeigten Sicherungseinrichtung wird auf den Oberrand eines Rinnenkörpers eine aufsetzbare Abdeckung angebracht. In den Seitenwänden des Rinnenkörpers sind im wesentlichen gegenüberliegend Ausnehmungen angeordnet. In die Ausnehmungen greift eine Traverse ein, welche quer zur Rinnenlängsachse im Innern der Rinne positioniert ist. Die aufsetzbare Abdeckung wird mit einer Befestigungseinrichtung schraublos oder mittels einer Schraubverbindung an der Traverse gegen Herausnehmen fixiert.In the security device shown there is the An attachable cover on the upper edge of a channel body appropriate. In the side walls of the channel body are in arranged substantially opposite recesses. In the A crossbar engages recesses which cross to the Channel longitudinal axis is positioned inside the channel. The attachable cover comes with a fastening device screwless or by means of a screw connection on the Crossbar fixed against removal.

Die Traverse selbst ist an mindestens einem Ende mit einer Klemmeinrichtung versehen, so daß ein Festsetzen der Traverse in den Ausnehmungen in den Seiteninnenwänden erfolgt.The traverse itself is at one end with one Provide clamping device so that the traverse becomes stuck in the recesses in the side walls.

Aus der DE 42 41 705 A1 ist eine Oberflächenentwässerungs-Einrichtung, insbesondere eine Entwässerungsrinne bekannt, welche eine Abdeckung aufweist, die wiederum mit Befestigungseinrichtungen am Rinnenkörper befestigbar ist. DE 42 41 705 A1 describes a surface drainage device, known in particular a drainage channel, which has a cover, which in turn with Fastening devices can be attached to the channel body.

Die Befestigungseinrichtungen umfassen einen Riegel, der an der Abdeckung gelagert ist und welcher in Richtung auf einen Längsrand der Abdeckung in eine Verriegelungsstellung bewegbar ist. Der Riegel kann weiterhin aus der Verriegelungsstellung in eine Öffnungsstellung verschoben werden.The fasteners include a latch that attaches to the cover is stored and which towards one Longitudinal edge of the cover can be moved into a locking position is. The bolt can continue from the locked position be moved to an open position.

Mittels des erläuterten Riegels kann eine schraublose Befestigung der Abdeckung vorgenommen werden. Dadurch, daß der Riegel Rasteinrichtungen aufweist, die mit der Abdeckung in federndem Eingriff stehen, ist sichergestellt, daß der Riegel mindestens in der Verriegelungsstellung in der entsprechenden Position fixiert ist. Hierdurch soll ein unbeabsichtigtes Öffnen bzw. Abnehmen der Abdeckung unmöglich werden.A screwless fastening can be done by means of the bolt described the cover. The fact that the Latch locking devices that with the cover in resilient engagement ensures that the bolt at least in the locking position in the corresponding Position is fixed. This is supposed to be an unintended Opening or removing the cover become impossible.

Es hat sich jedoch herausgestellt, daß bei Oberflächenentwässerungs-Einrichtungen, insbesondere Entwässerungsrinnen einer Belastungsklasse B bis F nach DIN 19580, d. h. Rinnen, deren Roste mit Fahrzeugen befahren werden, je nach der Belastungsklasse insbesondere beim axialen Überfahren und beim Bremsen von Fahrzeugen direkt auf dem Rinnenstrang, Schubkräfte zwischem den Abdeckrosten und den Zargen bzw. den Rinnenkörpern auftreten.However, it has been found that in surface drainage facilities, especially drainage channels a load class B to F according to DIN 19580, d. H. Gutters, whose grates are used by vehicles, depending on the Load class especially when driving over axially and when braking vehicles directly on the channel strand, Thrust between the cover grids and the frames or Gutter bodies occur.

Bei nicht ausreichend gesicherten Rosten und aufgrund der notwendigen Fertigungstoleranzen erfolgt ein Zusammenschieben der Roste entlang des Rinnenstranges, wodurch unzulässige Lücken oder Öffnungen in der Rinnenabdeckung entstehen. Dies führt zu Nachteilen in der Verkehrssicherheit.If the grates are not sufficiently secured and because of the necessary manufacturing tolerances are pushed together the grates along the channel strand, making inadmissible Gaps or openings arise in the channel cover. This leads to disadvantages in traffic safety.

Die eingangs beschriebenen Rostsicherungssysteme in schraubloser oder verschraubter Form können nur geringe axiale Schubkräfte aufnehmen.The rust protection systems described in screwless or screwed form can only small absorb axial thrust forces.

Insofern sind die bisher bekannten Lösungen zur axialen Sicherung nicht ausreichend, da insbesondere bei Entwässerungsrinnen ohne Kantenschutz bzw. mit Kantenschutz aus Blechprofilen die auftretenden Kräfte nicht ausreichend aufgenommen und über den Rinnenkörper abgeleitet werden können.In this respect, the previously known solutions for axial Securing not sufficient, especially with drainage channels without edge protection or with edge protection Sheet metal profiles not sufficiently absorbed the occurring forces and can be derived via the channel body.

Aus dem deutschen Gebrauchsmuster G 88 02 530.6 (entspricht dem Oberbegriff der Ansprüche 1 und 2) ist eine Entwässerungsrinne mit lösbar befestigter Abdeckung bekannt, wobei der Abdeckrost mit einer zusätzlichen formschlüssigen Arretierung versehen ist. Konkret besitzt der Rost an seiner Unterseite Nocken, die in eine Nut der Seitenwände des Rinnenkörpers eingreifen. Hierdurch ist zwar eine axiale Rostsicherung erreichbar, jedoch besteht nach wie vor die Gefahr, daß sich ein Riegelblech oder eine Befestigungstraverse löst und der Rost beim Überfahren herausgeschleudert werden kann.From the German utility model G 88 02 530.6 (corresponds to the preamble of claims 1 and 2) is one Drainage channel with detachably attached cover known, the cover grille with an additional positive Lock is provided. Specifically, the rust has on it Underside cams that fit into a groove in the side walls of the channel body intervention. This is an axial anti-rust device achievable, but there is still a risk that a locking plate or a fastening crossbar comes loose and the grate can be thrown out when driving over it.

Es ist daher Aufgabe der Erfindung, eine Entwässerungsrinne mit Sicherungseinrichtung und Abdeckrost anzugeben, mit welcher ein ausreichendes Fixieren des Abdeckrostes auf den jeweiligen Rinnenkörpern auch bei höheren Belastungsklassen und Rinnensystemen erreicht werden kann.It is therefore an object of the invention to provide a drainage channel Specify safety device and cover grille with which one sufficient fixing of the cover grate on the respective Channel bodies even with higher load classes and channel systems can be achieved.

Die Lösung der Aufgabe der Erfindung erfolgt mit einem Gegenstand jeweils nach den Merkmalen der unabhängigen Patentansprüche 1 oder 2, wobei die Unteransprüche mindestens zweckmäßige Ausgestaltungen oder Weiterbildungen umfassen. The object of the invention is achieved with an object each according to the features of the independent claims 1 or 2, the subclaims being at least expedient Embodiments or further training include.

Ein Grundgedanke der Erfindung besteht darin, daß die Sicherungseinrichtung mit einer im Rinnenkörper befindlichen Traverse zusammenwirkt, wobei die Traverse in bekannter Weise mit ihren Enden in zwei einander im wesentlichen gegenüberliegenden Ausnehmungen in den Seiteninnenwänden des Rinnenkörpers eingesetzt ist. Die Traverse befindet sich im eingesetzten Zustand quer zur Rinnenlängsachse im Inneren des Rinnenkörpers. Die Traverse dient zum schraublosen oder unter Verwendung einer Schraubverbindung erfolgenden Arretieren des Abdeckrostes von oben.A basic idea of the invention is that the Safety device with one in the channel body Traverse interacts, the traverse in a known manner with their ends in two essentially each other opposite recesses in the side walls of the Channel body is used. The traverse is in the used state transverse to the longitudinal axis of the gutter inside the Channel body. The traverse is used for screwless or under Use a screw connection to lock the Cover grate from above.

Erfindungsgemäß wird gemäß dem Grundgedanken der bei dieser Ausführungsform verwendete Abdeckrost so weitergebildet, daß von vorhandenen Tragstegen, die quer zur Rinne verlaufen, mindestens zwei benachbarte Tragstege mindestens abschnittweise eine solche Länge aufweisen, daß diese nach Aufsetzen des Abdeckrostes formschlüssig die Traverse beidseitig umgeben.According to the basic idea of the at this embodiment used grating so further developed that from existing supporting webs, which are transverse to the Gutter runs, at least two adjacent supporting bars at least in sections have such a length that these form-fitting after the cover grille Traverse surrounded on both sides.

Diese Traverse, auch Verriegelungsblech, wird also formschlüssig beidseitig von den Tragstegen umschlossen, so daß einerseits durch Verschrauben oder formschlüssige Verbindung unter Nutzung der Traverse und andererseits durch das erwähnte beidseitige Umschließen der Traverse das System sowohl gegen Herausnehmen des Abdeckrostes als auch gegen axiale Verschiebung selbständig ohne zusätzliche Maßnahmen gesichert ist. Bei dieser Ausführungsform werden erfindungsgemäß ausreichend dimensionierte Abdeckroste, Traversen und Rinnenkörper eingesetzt.This crossbeam, also the locking plate, will positively enclosed on both sides by the supporting webs, so that on the one hand by screwing or positive Connection using the traverse and on the other hand through the mentioned double-sided enclosing of the traverse the system both against removing the cover grate and against axial displacement independently without additional measures is secured. In this embodiment sufficiently large cover gratings according to the invention, Trusses and channel body used.

Der Vorteil gemäß dem Grundgedanken der Erfindung besteht in einer axialen Selbstsicherung durch die mindestens abschnittweise verlängerten Tragstege. The advantage according to the basic idea of the invention consists in an axial self-locking by the minimum Section bars extended in sections.

Bei einer zweiten Ausführungsform der Erfindung weist der Abdeckrost eine mindestens einseitige Randprofilierung, d. h. eine Profilierung, die in Längsrichtung der Rinne verläuft, auf, welche nach dem Aufsetzen des Abdeckrostes die Traverse formschlüssig beidseitig umgreift.In a second embodiment According to the invention, the cover grate has an at least one-sided Edge profiling, d. H. a profiling that in Longitudinal direction of the gutter runs on, which after the Attach the cover grate to the crossbar encompasses on both sides.

Bei dieser Ausführungsform wird also die Randprofilierung im Bereich der Lage der Traverse verlängert und besitzt vorzugsweise zwei Fortsätze, die eine U-Form bilden. Die U-förmige Profilierung des Randprofils des Abdeckrostes umgreift dann wie vorerwähnt die Traverse, so daß die erforderliche axiale Sicherung und das Einleiten von Schubkräften in den Rinnenkörper gewährleistet ist.In this embodiment, the edge profiling in Area of the position of the traverse extended and possesses preferably two extensions that form a U-shape. The U-shaped Profiling the edge profile of the grating then grips the traverse as mentioned, so that the required axial securing and the initiation of Thrust forces in the channel body is guaranteed.

Selbstverständlich können die erste und die zweite Ausführungsform gemäß dem Grundgedanken der Erfindung konbiniert werden dergestalt, daß das Randprofil des Abdeckrostes speziell ausgestaltet ist und mindestens zwei Tragstäbe so verlängert sind, daß diese die Traverse im aufgesetzten Zustand des Rostes umgreifen können.Of course, the first and the second Embodiment according to the basic idea of the invention be combined in such a way that the edge profile of the Cover grate is specially designed and at least two Support rods are extended so that the crossbar in can grasp the attached condition of the grate.

In einer weiteren Ausführungsform besitzt mindestens ein Schenkel der speziellen Randprofilierung des Abdeckrostes eine hervorstehende stiftartige Verlängerung, welche in eine zugeordnete Aussparung der Traverse eingreift, wodurch sich der Betrag aufnehmbarer und abzuleitender axialer Schubkräfte noch erhöht.In a further embodiment has at least one Leg of the special edge profile of the cover grate a protruding pin-like extension, which in a associated recess of the crossbar engages, which the amount of axial thrust that can be absorbed and derived still increased.

Ein weiterer Grundgedanke der Erfindung ist durch eine Kombination von Ausführungsformen nach dem zweiten Grundgedanken der Erfindung mit einer formschlüssigen Stift-oder Nockenverbindung gekennzeichnet.Another basic idea of the invention is through a Combination of embodiments after the second Basic ideas of the invention with a form-fitting pin or Cam connection marked.

Insbesondere bei diesem Grundgedanken der Erfindung wird durch die zusätzliche Stift- oder Nockensicherung die Traverse weitgehend von einer axialen Kräfteaufnahme befreit. Die ausgebildeten übergreifenden Seitenprofile des Abdeckrostes oder die speziellen oben erläuterten Tragstege übernehmen dann die Funktion der Lagesicherung der Traverse, so daß ein Herausgleiten letzterer aus den Aussparungen in den Seiteninnenwänden bei wiederholter, wechselnder Belastung des Rinnenkörpers insbesondere durch Überfahren vermieden wird.In particular with this basic idea of the invention is the additional pin or cam lock Traverse largely exempt from axial force absorption. The trained overlapping side profiles of the grating or take over the special supporting bars explained above then the function of securing the crosshead in position, see above that the latter slides out of the recesses in the Side inner walls with repeated, changing loading of the Channel body is avoided in particular by running over.

Hierdurch erhöht sich die Zuverlässigkeit des gesamten Rinnensystems und das Rugelblech kann unter Keinen Umstanden sich selbstandig lösen und in den Rinnenkörper fallen.This increases the reliability of the whole Channel system and the checker plate can under no circumstances detach itself and fall into the channel body.

Die Erfindung soll nachstehend anhand eines Ausführungsbeispieles und unter Zuhilfenahme von Figuren näher erläutert werden.The invention is intended to be explained below using an exemplary embodiment and explained in more detail with the help of figures become.

    • Beim Ausführungsbeispiel gemäß den Fig. 1a, 1b und 1d wird von einem Rinnenkörper 1 mit Seitenwänden 2 sowie einer in Aussparungen 3 angeordneten Traverse 4 ausgegangen.In the embodiment according to FIGS. 1a, 1b and 1d is from a channel body 1 with side walls 2nd and a crossbar 4 arranged in recesses 3 went out.

    Weiterhin ist hier ein Guß-Stegrost 30 als Abdeckrost vorhanden. Der Guß-Stegrost 30 besitzt eine Vielzahl von im wesentlichen quer zum Rinnenkörper 1 verlaufenden Tragstegen 31, welche gemäß den Fig. 1a, 1b und 1d nach unten, d. h. zum Rinnenboden hin konisch verjüngt sind. Zwischen den Tragstegen 31 sind Einlauföffnungen 32 vorhanden. Beim zweiten Ausführungsbeispiel sind mindestens zwei benachbarte Tragstege 31, gemäß Fig. 1a und 1b die Tragstege 310 und 320, so nach unten, d. h. zum Rinnenboden hin verlängert, daß die sich gegenüberliegenden Innenseiten der Tragstege 310 und 320 mindestens einen Abschnitt der Traverse 4 formschlüssig umgreifen. Der Abdeckrost 30 ist mit einer Schraubverbindung 6 an der Traverse 4 befesligbar. Durch die erwähnte konische Ausbildung der Tragstege 310, 320 werden einerseits Toleranzen beim axialen Sichern und Arretieren des Guß-Stegrostes 30 mittels der Traverse 4 ausgeglichen, und andererseits entsteht zusätzlich eine Keilwirkung, so daß unerwünschtes Spiel in Rinnenlängsrichtung vermieden wird. Das vorstehende Ausführungsbeispiel gewährleistet bei Anwendung von Gußrosten eine ausreichende axiale Sicherung und bei Maschenrosten primär eine Sicherung der Traverse bzw. des Riegelbleches gegen Herausdrehen aus den Ausnehmungen in den Seiteninnenwänden des Rinnenkörpers. Furthermore, here is one Cast iron grating 30 available as a cover grate. The cast footbridge 30 has a variety of essentially transverse to Channel body 1 extending support webs 31, which according to the 1a, 1b and 1d down, d. H. towards the gutter floor are tapered. Are between the supporting webs 31 Inlet openings 32 available.

The grating 30 can be attached to the crossbar 4 with a screw connection 6. Due to the conical design of the supporting webs 310, 320 are tolerances on the one hand in axial securing and Locking the cast web grating 30 by means of the cross member 4 balanced, and on the other hand there is an additional Wedge action, so that unwanted play in the longitudinal direction of the channel is avoided. The above embodiment ensures adequate when using cast iron gratings axial securing and primarily a securing for mesh gratings the crossbeam or the locking plate against unscrewing the recesses in the side inner walls of the channel body.

    Fig. 1c zeigt eine Variante eines Guß-Stegrostes 30, welcher verkürzte bzw. kürzere Tragstege 330 aufweist. Zur Gewährleistung der axialen Sicherung in Längsrichtung der Rinne ist das Randprofil 34 des Guß-Stegrostes 30 so ausgebildet, daß die Traverse 4 in einem zur Seiteninnenwand 2 hin gerichteten Abschnitt formschlüssig umgriffen wird.Fig. 1c shows a variant of a cast web grate 30, which has shortened or shorter support webs 330. For Ensuring the axial securing in the longitudinal direction of the Channel is the edge profile 34 of the cast web grating 30 so trained that the cross member 4 in a side wall 2 directed section is positively embraced.

    Die spezielle Randprofilierung umfaßt dabei zwei gegenüberliegende Schenkel 35, wovon mindestens einer einen U-förmigen Abschnitt zum Umgreifen der Traverse 4 aufweist.The special edge profile includes two opposite Leg 35, at least one of which is U-shaped Has section for gripping the cross member 4.

    Die Innenseiten des U-förmigen Ausschnitts, nämlich die Seiten, welche mit der Traverse 4 in Wirkverbindung stehen, können eine Keilflächenform aufweisen, so daß sich eine spielfreie Arretierung des Guß-Stegrostes 30 ergibt.The inside of the U-shaped cutout, namely the Sides, which are in operative connection with the traverse 4, can have a wedge surface shape, so that a backlash-free locking of the cast web grating 30 results.

    In einer Variante des Ausführungsbeispiels kann die Gußrostarretierung auf der Basis verlängerter Tragstege mit der Randprofilarretierung in einem seitlichen Abschnitt der Traverse kombiniert werden.In a variant of the exemplary embodiment, the Cast iron lock on the basis of extended support bars with the edge profile lock in a lateral section of the Traverse can be combined.

    Beim zweiten Ausführungsbeispiel gemäß Fig. 2a bis 2c wird von einer Kombination der axialer Sicherungsvarianten ausgegangen. Diese Kombination erfolgt mit dem Ziel, daß die axialen Kräfte durch Stifte oder Nocken 9,10,11,12 abgeleitet werden und die Tragstege oder Randprofile das Herausdrehen der Traverse aus den Ausnehmungen der Seiteninnenwände verhindern. In the second embodiment according to FIGS. 2a to 2c from a combination of the axial securing variants went out. This combination is done with the aim that the axial forces are derived by pins or cams 9,10,11,12 and the supporting webs or edge profiles are unscrewed the traverse from the recesses in the side walls prevent.

    Auch beim zweiten Ausführungsbeispiel ist ein Rinnenkörper 1 mit Seitenwänden 2 vorhanden, wobei in einer Aussparung 3 in den Seiteninnenwänden eine Traverse 4 im wesentlichen quer zur Längsrichtung des Rinnenkörpers angeordnet ist. Der Guß-Stegrost 30 des dritten Ausführungsbeispiels besitzt in einem Randabschnitt 40 des Randprofils eine Bohrung oder Aussparung 41 zur Aufnahme eines freien Abschnittes 11 eines Stiftes 10, welcher in der Seitenwand 2 des Rinnenkörpers 1 fixiert ist.A channel body 1 is also in the second exemplary embodiment with side walls 2, with 3 in a recess a cross member 4 essentially transverse to the side inner walls is arranged to the longitudinal direction of the channel body. The cast footbridge 30 of the third embodiment has in one Edge section 40 of the edge profile a hole or recess 41 for receiving a free section 11 of a pin 10, which is fixed in the side wall 2 of the channel body 1.

    Bei diesem Ausführungsbeispiel ist es durch einfache Dimensionierung möglich, dafür Sorge zu tragen, daß axiale Schubkräfte, welche beim Überfahren in Längsrichtung auf den Abdeckrost einwirken, primär durch die formschlüssige Verbindung zwischen dem Stift 10 und dem Guß-Stegrost 30 aufgenommen und in den Rinnenkörper 1 weitergeleitet werden.In this embodiment, it is simple Sizing possible to ensure that axial Thrust forces, which when driving over in the longitudinal direction on the Act cover grate, primarily through the form-fitting Connection between the pin 10 and the cast grating 30th recorded and passed into the channel body 1.

    Das Umgreifen der Traverse 4 mit den Tragstegen 310 und 320 dient dann vorzugsweise der Lagesicherung der Traverse selbst, so daß diese bei dynamischen und Wechselbelastungen sich nicht aus den Aussparungen 3 herausdreht oder herausschwenkt und dadurch die Gefahr besteht, daß der betreffende Abdeckrost nach oben herausgeschleudert wird.Gripping the crossbar 4 with the support bars 310 and 320 then preferably serves to secure the position of the traverse itself, so this with dynamic and alternating loads does not turn out of the recesses 3 or swings out and there is a risk that the relevant covering grate is flung out upwards.

    Alles in allem gelingt es mit den beschriebenen Ausführungsbeispielen, bei Entwässerungsrinnen mit oder ohne Kantenschutz aus Blechprofilen 8,23,24, eine ausreichende axiale Sicherung, insbesondere beim Überfahren entsprechender Abdeckroste des Rinnensystems in Längsrichtung, zu erreichen, ohne daß ein unerwünschtes Zusammenschieben der Abdeckroste mit entsprechenden Nachteilen hinsichtlich der Verkehrssicherheit auftritt.All in all, the described exemplary embodiments succeed in for drainage channels with or without edge protection from sheet metal profiles 8, 23, 24, sufficient axial securing, especially when driving over the corresponding cover grids Channel system in the longitudinal direction to achieve without a undesired pushing together of the cover grids corresponding disadvantages with regard to traffic safety occurs.
