Abstract

The device has a locking bolt (22) which is turnable into a position relative to a stud. In another position, it is positively connected to the stud. The locking bolt has two peripheral angled surfaces (39) on its top, centrally symmetrical to the stud axis. The bolt has a lower projection coaxially to the stud. The projection has two diametrically opposite contact shoulders, for a cross pin, which passes through the stud. Next to the stop shoulders, the projection has several steps, each with a helical surface. The cross pin locks on a next connecting step.

Description

Eine Vorrichtung zum Verriegeln eines Rostes auf einer Entwässerungsrinne ist aus dem EP-Patent 112 287 bekannt. Die Rinne hat an den gegenüberliegenden Seitenwänden Ausnehmungen, in welche ein Riegel durch Drehen eingeschwenkt werden kann. Der Riegel ist durch eine Schraube mit dem Rost verbunden. Dreht man die Schraube im anziehenden Sinn, wird zunächst der Riegel bis zu einem Anschlag in die Ausnehmungen eingeschwenkt und anschliessend gegen den Rost verspannt, sodass der Rost sicher auf der Rinne gehalten ist. Diese Vorrichtung hat sich sehr bewährt. Allerdings ist der Arbeitsaufwand zum Verriegeln und Lösen nicht unbeträchtlich.A device for locking a grate on a drainage channel is known from EP patent 112 287. The channel has recesses on the opposite side walls, into which a bolt can be pivoted by turning. The bolt is connected to the grate by a screw. If the screw is tightened, the bolt is first swung into the recesses as far as it will go and then clamped against the grate so that the grate is held securely on the channel. This device has proven very successful. However, the work involved in locking and unlocking is not inconsiderable.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung der eingangs genannten Art derart auszubilden, dass der Arbeitsaufwand zum Verriegeln und Lösen der Verbindung reduziert wird. Diese Aufgabe wird durch die- kennzeichnenden Merkmale des Anspruchs 1 gelöst.The object of the present invention is to design a device of the type mentioned at the outset in such a way that the work involved in locking and releasing the connection is reduced. This object is achieved by the characterizing features of claim 1.

In Figur 1 ist von einer Entwässerungsrinne 1 nur der obere Teil der beiden Seitenwände 2 aus Polyesterbeton dargestellt. Diese haben oben längs verlaufende Ausnehmungen 3, in welche ein Rost 4 eingesetzt ist. Der Rost 4 hat seitlich zwei Längsrippen 5, die auf dem Grund der Ausnehmungen 3 aufliegen, sowie diese verbindende Querrippen 6. Mindestens zwei der Querrippen 6 sind in der Mitte verdickt und haben mittig eine Durchgangsbohrung 7 mit einer Ansenkung 8 zur Aufnahme des Schaftes 12 bzw. des Kopfs 13 eines Bolzens 14 sowie einer Unterlagsscheibe 15.In Figure 1 of a drainage channel 1, only the upper part of the two side walls 2 made of polyester concrete is shown. These have longitudinally extending recesses 3 in which a grate 4 is inserted. The grate 4 has two longitudinal ribs 5, which rest on the bottom of the recesses 3, and transverse ribs 6 connecting them. At least two of the transverse ribs 6 are thickened in the middle and have a through hole 7 in the middle with a countersink 8 for receiving the shaft 12 or the head 13 of a bolt 14 and a washer 15.

In der Querebene der Bohrung 7 ist in den Wänden 2 auf gleicher Höhe je ein Riegelhaltekasten 20, z.B. gemäss EP-Patent Nr. 112 287, aus Kunststoff mit inneren Ausnehmungen 21 eingegossen. In diese wird durch Drehen des Bolzens 14 im Uhrzeigersinn in der Darstellung nach Figur 2 ein Riegel 22 eingefahren und anschliessend durch Weiterdrehen des Bolzens 14 gegen den Rost 4 gespannt. Der Riegel 22 kann z.B. aus faserverstärktem Kunststoff spritzgegossen sein. Der Riegel 22 hat an der Unterseite einen zylindrischen Vorsprung 23 mit zwei zentralsymmetrisch zur Achse 29 des Bolzens 14 stufenweise wendelförmig ansteigenden Spannflächen 24. Auf eine wendelförmig ansteigende Fläche 25 folgt jeweils eine Stufe 26 mit geringerer, entgegengesetzter Neigung. Die unterste Stufe 26a wird von einer Anschlagfläche 27 und die oberste Stufe 26 von einer Anschlagfläche 28 begrenzt. Ein durch den Schaft 12 gesteckter Querstift 32 mit rechteckigem Querschnitt liegt an den Flächen 25, 26 an. Er wird bei der Montage zusammen mit dem Schaft 12 durch eine Durchgangsbohrung 33 und zwei Schlitze 34 des Riegels 22 und des Vorsprungs 23 durchgesteckt. Der Schlitz 34 mündet z.B. in der tiefsten Stufe 26a beabstandet von der Anschlagfläche 27 und vom Uebergang dieser Stufe 26a zur Wendelfläche 25, damit der Riegel 22 beim Lösen und Spannen nicht abfällt.In the transverse plane of the bore 7, a transom holding box 20, for example according to EP Patent No. 112 287, made of plastic with internal recesses 21 is cast into the walls 2 at the same height. A bolt 22 is inserted into this by rotating the bolt 14 clockwise in the illustration according to FIG. 2 and then tensioned against the grate 4 by further turning the bolt 14. The latch 22 can be injection molded, for example, from fiber-reinforced plastic. The latch 22 has on the underside a cylindrical projection 23 with two clamping surfaces 24 that rise gradually in a helical manner centrally with respect to the axis 29 of the bolt 14. A helically rising surface 25 is followed in each case by a step 26 with a lower, opposite inclination. The bottom step 26a is delimited by a stop surface 27 and the top step 26 by a stop surface 28. A transverse pin 32 with a rectangular cross section inserted through the shaft 12 lies against the surfaces 25, 26. It is pushed through together with the shaft 12 through a through hole 33 and two slots 34 of the bolt 22 and the projection 23. The slot 34 opens, for example, in the deepest step 26a spaced from the stop surface 27 and from the transition of this step 26a to the helical surface 25, so that the latch 22 does not fall off when loosening and tensioning.

Beim Einsetzen des Rostes ruht der Riegel 22 mit der tiefsten Stufe 26a auf dem Stift 32. Beim Drehen des Bolzens 14 am Kopf 13 wird der Riegel 22 zunächst in Eingriff mit den Riegelhaltekasten 20 gedreht, bis die einen Flächen 37 des Riegels 22 an Anschlagflächen 38 der Kasten 20 anliegen. Beim Weiterdrehen gleitet der Querstift 32 auf der ersten Wendelfläche 25, bis er auf der zweiten Stufe 26 einschnappt. Je nach Toleranz kann noch um eine oder zwei Stufen 26 weitergedreht und damit die Spannkraft erhöht werden. Ein Weiterdrehen über die oberste Stufe 26 ist wegen der Anschlagfläche 28 nicht möglich.When the grate is inserted, the bolt 22 with the deepest step 26a rests on the pin 32. When the bolt 14 on the head 13 is rotated, the bolt 22 is first rotated into engagement with the bolt holding box 20 until one surface 37 of the bolt 22 rests on stop surfaces 38 the box 20 abut. When turning further, the cross pin 32 slides on the first helical surface 25 until it snaps onto the second step 26. Depending on the tolerance, one or two steps 26 can be rotated further and thus the Elasticity can be increased. A further turning over the top step 26 is not possible because of the stop surface 28.

Beim Lösen der Verbindung wird der Bolzen 14 im umgekehrten Sinn gedreht, bis der Querstift 32 an der Anschlagfläche 27 ansteht, worauf der Riegel 22 durch die nun formschlüssige Verbindung zwangsweise mitgedreht wird.When the connection is released, the bolt 14 is rotated in the opposite direction until the cross pin 32 is in contact with the stop surface 27, whereupon the bolt 22 is also rotated by the now positive connection.

Zum Spannen und Lösen braucht der Bolzen 14 bloss etwa eine viertel bis eine halbe Umdrehung gedreht zu werden, sodass die Montage und Demontage des Rostes auf der Rinne 1 sehr rasch erfolgt. Durch die zwangsweise Mitnahme des Riegels 22 ist das Lösen und Spannen zuverlässig.For tensioning and loosening, the bolt 14 only needs to be rotated about a quarter to a half turn, so that the mounting and dismounting of the grate on the channel 1 takes place very quickly. Due to the forced entrainment of the bolt 22, the loosening and tensioning is reliable.

Um ein sicheres Einfahren des Riegels 22 in die Kasten 20 zu gewährleisten, kann der Riegel 22 an der Oberseite anschliessend an die Flächen 37 Schrägflächen 39 aufweisen.In order to ensure that the latch 22 is securely retracted into the box 20, the latch 22 can have inclined surfaces 39 on the upper surface 37.

Die Schlitze 34 können auch weggelassen und die Querstifte 32 erst bei der Montage in entsprechende Durchgangsöffnungen 40 des Schaftes 12 eingesetzt werden. Der Schaft 12 kann mehrere solcher Oeffnungen 40 auf unterschiedlicher Höhe aufweisen, damit der gleiche Bolzen 14 für unterschiedliche Rinnenhöhen passt.The slots 34 can also be omitted and the transverse pins 32 can only be inserted into corresponding through openings 40 of the shaft 12 during assembly. The shaft 12 can have a plurality of such openings 40 at different heights so that the same bolt 14 fits for different channel heights.
