Description

Die Erfindung betrifft eine Entwässerungsrinne von der im Oberbegriff des Anspruchs 1 angegebenen Art. Entwässerungsrinnen dieser Art sind aus DE-GM 81 26 295 und DE-GM 83 33 233 bekannt. Bei ihnen ist der Riegel als starrer Knebel ausgebildet, der in Gewindeeingriff mit einem Schraubbolzen an der Abdeckung gelagert ist. Die Widerlager sind Ausnehmungen in den Seitenwänden des Rinnenkörpers. Der Riegel muß mittels des Schraub­bolzens in die Ausnehmungen hineingeschwenkt und dann festgezogen werden. Dies ist zwar eine einfache und kostengünstige Konstruktion. Da der Riegel aber einer­seits zusammen mit dem Schraubbolzen geschwenkt werden soll, andererseits aber auf dem Schraubbolzen drehbar sein muß, um festgezogen zu werden, kann es in der Praxis vorkommen, daß der Riegel beim Drehen des Schraub­bolzens nicht mitgenommen wird. Dies kann dazu führen, daß beim Verriegeln der Abdeckung der Riegel nicht in die volle Riegellage verschwenkt wird, sondern z.B. die Widerlager nur unvollkommen untergreift, oder daß beim Entriegeln der Riegel nicht von den Widerlagern weggeschwenkt werden kann, weil er auf dem Schraub­bolzen durchdreht.The invention relates to a drainage channel of the type specified in the preamble of claim 1. Drainage channels of this type are known from DE-GM 81 26 295 and DE-GM 83 33 233. In the case of them, the bolt is designed as a rigid toggle, which is mounted on the cover in threaded engagement with a screw bolt. The abutments are recesses in the side walls of the channel body. The bolt must be pivoted into the recesses using the screw bolt and then tightened. While this is a simple and inexpensive construction. However, since the bolt is to be pivoted on the one hand together with the screw bolt, on the other hand it is rotatable on the screw bolt must be in order to be tightened, it can happen in practice that the bolt is not taken when turning the bolt. This can lead to the fact that when the cover is locked, the bolt is not pivoted into the full bolt position, but, for example, only imperfectly engages under the abutment, or that when the bolt is unlocked, it cannot be pivoted away from the abutment because it turns on the screw bolt.

Der Erfindung liegt die Aufgabe zugrunde, eine Entwässe­rungsrinne der angegebenen Art so auszugestalten, daß die Verriegelung betriebssicherer arbeitet.The invention has for its object to design a drainage channel of the type specified so that the lock works more reliably.

Die erfindungsgemäße Lösung der Aufgabe ist im Anspruch 1 angegeben. Die Unteransprüche betreffen vorteilhafte wei­tere Ausgestaltungen.The achievement of the object is specified in claim 1. The subclaims relate to advantageous further refinements.

Ausführungsformen der Erfindung sind in den Zeichnungen dargestellt. Es zeigt:

  • Fig. 1 einen Querschnitt durch eine Entwässerungsrinne mit einer ersten Ausführungsform des Riegels;
  • Fig. 2 einen Querschnitt durch eine Entwässerungsrinne mit einer zweiten Ausführungsform des Riegels.
Embodiments of the invention are shown in the drawings. It shows:
  • 1 shows a cross section through a drainage channel with a first embodiment of the bar.
  • Fig. 2 shows a cross section through a drainage channel with a second embodiment of the bar.

Gemäß Fig. 1 hat die Entwässerungsrinne einen Rinnen­körper 1, der einstückig aus einem geeigneten Material, vorzugsweise Polyesterbeton, gefertigt ist. Auf Auf­lageflächen 3 des Rinnenkörpers ist eine Abdeckung 5 aufgelegt, die bei der gezeigten Ausführungsform als Rost ausgebildet ist. Ein von der Oberseite der Ab­deckung her betätigbarer Schraubbolzen 7 steht in Gewin­deeingriff mit einem zweiarmigen Druckkörper 9. Zwi­schen diesem und der Unterseite des Rostes 5 ist eine zweiarmi­ge Bügel-Feder 11 eingespannt, die mittels einer mittigen Öffnung auf den Schraubbolzen 7 zentriert ist und deren gegeneinander abgewinkelte Arme 11a, 11b sich gegen den Druckkörper 9 abstützen. Mit den aufwärts gebogenen Enden der Arme 11a, 11b kann die Feder 7 verriegelnd in Ausneh­mungen 13 in den Seitenwänden des Rinnenkörpers 1 eingreifen.1, the drainage channel has a channel body 1 which is made in one piece from a suitable material, preferably polyester concrete. A cover 5 is placed on contact surfaces 3 of the channel body, which in the embodiment shown is designed as a grate. A bolt 7, which can be actuated from the top of the cover, is in threaded engagement with a two-armed pressure element 9. Between this and the underside of the grate 5, a two-armed spring clip 11 is clamped, which is centered on the bolt 7 by means of a central opening and their opposite one another angled arms 11a, 11b are supported against the pressure body 9. With the upwardly bent ends of the arms 11a, 11b, the spring 7 can engage in locking recesses 13 in the side walls of the channel body 1.

Der mittlere Teile der Feder 11 ist zwischen zwei umge­börtelten Stegen 15 an der Unterseite des Rostes 5 geführt und dadurch am Drehen gehindert. Entsprechend abgewinkel­te Flansche 17 des Druckkörpers 9 umgreifen die Arme 11a, 11b der Feder 11 seitlich, wodurch auch der Druckkörper 9 an einer Drehung relativ zum Rost 5 gehindert ist.The middle part of the spring 11 is guided between two flanged webs 15 on the underside of the grate 5 and is thereby prevented from rotating. Correspondingly angled flanges 17 of the pressure body 9 laterally encompass the arms 11a, 11b of the spring 11, as a result of which the pressure body 9 is also prevented from rotating relative to the grate 5.

Durch Drehen des Schraubbolzens 7 kann das Druckstück 9 auf und ab bewegt werden. Die Feder 11 ist so vorgespannt, daß die Federkraft die Arme 11a, 11b stärker gegenein­ander abzuwinkeln sucht. Die untere Endstellung des Druck­stücks 9 ist im linken Teil von Fig. 1 bei 9ʹ gestrichelt dargestellt. Sie wird durch den Querstift 18 festgelegt. In dieser Stellung sind die Enden der Arme 11a frei von den Ausnehmungen 13, und der Rost 5 kann vom Rinnen­körper 1 abgehoben werden. Wird bei aufgesetztem Rost der Schraubbolzen 7 gedreht und dadurch das Druckstück nach oben bewegt, so werden die Arme 11a, 11b der Feder 11 entgegen der Federkraft zunehmund gespreizt, so daß ihre Enden in die Ausnehmungen 13 eingreifen und sich gegen die als Widerlager dienende obere Wand der Ausnehmung 13 anle­gen, wodurch der Rost 5 am Rinnenkörper 1 verriegelt und verspannt ist.By turning the screw bolt 7, the pressure piece 9 can be moved up and down. The spring 11 is biased that the spring force tries to angle the arms 11a, 11b more strongly against one another. The lower end position of the pressure piece 9 is shown in dashed lines in the left part of FIG. 1 at 9ʹ. It is determined by the cross pin 18. In this position, the ends of the arms 11a are free of the recesses 13 and the grate 5 can be lifted off the channel body 1. If the bolt 7 is rotated while the grate is in place and the pressure piece is thereby moved upwards, the arms 11a, 11b of the spring 11 are increased and spread against the spring force, so that their ends engage in the recesses 13 and abut against the upper wall serving as an abutment create the recess 13, whereby the grate 5 is locked and braced on the channel body 1.

Bei der Ausführungsform nach Fig. 2 sind zwei voneinander getrennte starre Riegelarme 12a, 12b vorgesehen, die mittels gabelförmiger Gelenkbolzen 19 auf einem U-Blech 20 gelagert sind, das seinerseits von einer durch einen Stift 21 gehaltenen Beilagscheibe 23 auf den Schraubbol­zen 7 abgestützt wird. Die Enden der Arme 12a, 12b stützen sich auf einem Druckstück 9 ab, welches mit dem Schraub­bolzen 7 in Gewindeeingriff steht. Die Arme 12a, 12b sind zwischen zwei Versteifungsrippen 15 des Abdeckrostes 5 ge­führt, und ihre Enden haben an der Unterseite Führungs­nuten 25, in die eine Führungsleiste 27 des Druckstücks 9 eingreift. Auf diese Weise sind die Arme 12a und 12b und das Druckstück 9 in der Horizontalebene undrehbar an dem Abdeckrost 5 geführt und nur in der Vertikalebene beweglich.In the embodiment according to FIG. 2, two rigid locking arms 12a, 12b are provided, which are mounted on a U-plate 20 by means of fork-shaped joint bolts 19, which in turn is supported on the screw bolt 7 by a washer 23 held by a pin 21. The ends of the arms 12a, 12b are supported on a pressure piece 9 which is in threaded engagement with the screw bolt 7. The arms 12a, 12b are guided between two stiffening ribs 15 of the grating 5, and their ends have guide grooves 25 on the underside, in which a guide bar 27 of the pressure piece 9 engages. In this way, the arms 12a and 12b and the pressure piece 9 guided in a non-rotatable manner on the cover grate 5 in the horizontal plane and movable only in the vertical plane.

In der in Fig. 2 links gezeigten Lage ist das Druckstück 9 nach oben geschraubt und spreizt die Arme 12a, 12b ausein­ander, so daß deren Enden in taschenartige Ausnehmungen 13 des Rinnenkörpers 1 eingreifen und den Abdeckrost 5 am Rinnen­körper 1 verriegeln. Durch Drehen des Schraubbolzens 7 kann das Druckstück in die in Fig. 2 rechts angedeutete unte­re Endlage 9ʹ bewegt werden. Die Riegelarme 12a, 12b fol­gen durch Eigengewicht nach und gelangen in eine stärker nach unten abgeknickte Lage, in der ihre Enden außer­halb der Ausnehmungen 13 liegen, so daß der Abdeckrost 5 entriegelt ist und nach oben abgehoben werden kann.In the position shown on the left in FIG. 2, the pressure piece 9 is screwed upwards and spreads the arms 12a, 12b apart, so that their ends engage in pocket-like recesses 13 in the channel body 1 and lock the grating 5 on the channel body 1. By turning the screw bolt 7, the pressure piece can be moved into the lower end position 9ʹ indicated on the right in FIG. 2. The locking arms 12a, 12b follow by their own weight and arrive in a more downwardly bent position, in which their ends lie outside the recesses 13, so that the grating 5 is unlocked and can be lifted off.

Die dargestellte Riegelvorrichtung ist auch bei Abdeckun­gen anwendbar, die nicht als Rost, sondern als Deckel ausgebildet sind. Ferner brauchen die von den Enden des Riegels untergriffenen Widerlager nicht als Ausnehmun­gen in der Rinnenseitenwand ausgebildet sein, es kann sich auch um Vorsprünge handeln, die von der Rinnenseiten­wand nach innen ragen.The locking device shown can also be used for covers which are not designed as a grate but as a cover. Furthermore, the abutments which are gripped by the ends of the latch need not be formed as recesses in the gutter side wall; they can also be projections which project inwards from the gutter side wall.
