These adjacent sections 311, 312 form a perpendicular leg 31 of the frame 3. By Bending the free end of section 312 by 90 ° forms a horizontal one Leg 32 out. With its side facing the bottom 22 of the drainage channel 2 the leg 32 of the frame 3 rests on the leg 21 of the gutter 2. in the The embodiment is also the leg 21 of the gutter 2 facing End of section 311 on leg 21; it closes flush with that Leg 21 facing side of the leg 32 of the frame 3. It's about it possible that the section 311 is not flush with the leg 32, but protrudes beyond it. In this case, section 311 includes the Leg 21 of the gutter 2 laterally, for an exact fixation of the frame 3 on the Ensure drainage channel 2. The attachment of the frame 3 on the legs 21 the drainage channel 2 is carried out, for example, by tie rods. For this purpose, in the leg 32 of the frame 3 holes can be provided in which bushings riveted are. At their ends facing away from the frame 3 are monier iron in the sockets inserted, which are riveted to the sockets. The tie rods are in the legs 21 poured the gutter 2.

Aus dem Abschnitt 312 des Schenkels 31 ist eine Zunge 33 ausgelöst. Die Zunge 33 hat eine rechteckige Grundform. Sie ist an einer ihrer Seiten 332 mit dem Abschnitt 312 des Schenkels 31 verbunden; die übrigen drei Seiten sind frei. Die Seite 332 verläuft senkrecht zur Längsrichtung des Schenkels 31. Die Zunge 33 ist unter einem Winkel zum Schenkel 31 angeordnet. Dieser Winkel ist durch Herausziehen des freien Endes der Zunge 33 aus dem Abschnitt 312 hervorgerufen. Durch die winklige Anordnung der Zunge 33 zum Schenkel 31 weist sie Federeigenschaften auf. Da die Zunge 33 darüber hinaus aus dem Schenkel 31 an drei Seiten ausgelöst ist, ist sie unter hoher Belastung in der Lage, sich in den Abschnitt 312 des Schenkels 31 zurückzuziehen (Figur 2). Die Zunge 33 weist eine Nase 331 auf. Sie ist in ihrem dem Schenkel 32 zugewandten Bereich angeordnet. Im Ausführungsbeispiel ist die Nase 331 durch eine Biegung der Zunge 33 hervorgerufen. Darüber hinaus ist die Zunge 33 nach Art eines Torsionsstabs verdreht ausgeführt. Trotz der Anordnung der Zunge 33 unter einem Winkel zum Schenkel 31 ist der Schenkel 31 auch im Bereich der Zunge 33 aufgrund der der gebogenen Ausführung auf der der Rinne 2 abgewandten Seite weitgehend geschlossen, so daß kein Schmutz in den Bereich zwischen Zunge 33 und Abschnitt 311 gerät.A tongue 33 is triggered from the section 312 of the leg 31. The tongue 33 has a rectangular basic shape. It is on one of its sides 332 with the section 312 of the leg 31 connected; the remaining three pages are free. Page 332 runs perpendicular to the longitudinal direction of the leg 31. The tongue 33 is under one Angle to the leg 31 arranged. This angle is free by pulling it out End of the tongue 33 caused by the section 312. Because of the angular arrangement the tongue 33 to the leg 31 has spring properties. Since the Tongue 33 is also triggered from the leg 31 on three sides, it is able to withdraw into section 312 of leg 31 under high load (Figure 2). The tongue 33 has a nose 331. She is in her that Leg 32 facing region arranged. In the embodiment is the nose 331 caused by a bend in the tongue 33. In addition, the tongue is 33 twisted like a torsion bar. Despite the arrangement of the tongue 33 the leg 31 is also at an angle to the leg 31 in the region of the tongue 33 due to the curved design on the side facing away from the channel 2 largely closed, so that no dirt in the area between tongue 33rd and section 311.

Der Rost 1 wird beim Einbau in die Zargen 3 einfach in die sich zwischen den Zargen 3 ergebende Öffnung eingelegt. Unter Einwirken einer Kraft gleitet der Rost zunächst mit der Schrägen 16 und im Anschluß daran mit dem Abschnitt 15 entlang der Zunge 33, wobei die Zunge 33 in Richtung des Abschnitts 311 des Schenkels 31 gedrückt wird. Ist der Abschnitt 15 über die Nase 331 der Zunge 33 hinweggeglitten, schnappt die Zunge 33 in die durch die Anphasung 14 und die Verjüngung 13 an dem Rost 1 ausgebildete Vertiefung ein. In diesem Zustand liegt der Rost 1 auf dem Schenkel 32 der Zargen 3 auf. Die Zunge 33 schmiegt sich im eingelegten Zustand des Rostes 1 an die Verjüngung 13 und die Anphasung 14 an. Durch die gebogene und gedrehte Ausführung der Zunge 33 ist eine sehr hohe Klemmkraft erzielt, so daß eine wirksame Sicherung gegen Herausspringen des Rostes aus den Zargen erzielt ist. Durch die in die Vertiefung zwischen Verjüngung 13 und Anphasung 14 hervorstehende Nase 331 der Zunge 33 ist darüber hinaus ein Verschieben des Rostes in den Zargen 3 verhindert.The grate 1 is simply installed in the frames 3 in between the frames 3 resulting opening inserted. The grate initially slides under the action of a force with the bevel 16 and then with the section 15 along the tongue 33, the tongue 33 being pressed in the direction of the section 311 of the leg 31 becomes. If section 15 has slid over nose 331 of tongue 33, snaps the tongue 33 in the through the chamfer 14 and the taper 13 on the Grate 1 trained recess. In this state, the grate 1 is on the Leg 32 of the frame 3. The tongue 33 nestles in the inserted state of the grate 1 to the taper 13 and the chamfer 14. Through the curved and rotated version of the tongue 33 a very high clamping force is achieved, so that effective protection against the rust jumping out of the frames is achieved. By protruding into the recess between taper 13 and chamfer 14 Nose 331 of tongue 33 is also a shifting of the grate in the frame 3 prevented.

Es ist darüber hinaus möglich, die Zargen 3 aus einem nicht um 180° umgefalzten Blechstreifen herzustellen. In diesem Fall ist die Zunge 33 vollständig aus dem Schenkel 31 der Zarge 3 gebildet. Weiterhin ist es möglich, den Rost 1 mit ebenen Längsseiten auszubilden. Auch in diesem Fall ist durch die Zunge 33 eine sehr hohe Klemmkraft erzielt. Des weiteren können auch an den Stirnseiten des Rostes 1 Verjüngungen 13, Anphasungen 14, sowie Schrägen 16 vorgesehen sein. Auch können an den Stirnseiten Zargen vorgesehen sein, die ebenfalls mit Zungen 33 versehen sind.It is also possible to make the frame 3 from a not folded by 180 ° To produce metal strips. In this case, the tongue 33 is completely out of the Leg 31 of the frame 3 is formed. It is also possible to level the grate 1 Form long sides. In this case too, the tongue 33 is very high Clamping force achieved. Furthermore, tapering can also take place on the end faces of the grate 13, chamfering 14, and bevels 16 may be provided.
