Abstract

The channel (1) has apertures (11) in the side walls (2). A bolt (12) connected via a stud (9) to the cover, locks into the apertures. A tension element (14) is placed on the underside of the bolt, with a helical tension surface (17) on the underside. When securing the cover (4), a cross pin (24) on the stud engages on the tension surface. A spring element (19), formed by flexible bolt arms, supports the tension element relative to the cover. The bolt consists of metal, preferably rustproof spring steel.

Description

Eine Sicherungsvorrichtung zum Sichern eines Abdeckrostes auf einer Entwässerungsrinne ist aus dem EP-Patent 112 287 bekannt. Die Rinne hat an gegenüberliegenden Seitenwänden Ausnehmungen, in welche ein Riegel (Arretierungsbügel) durch Drehen eingeschwenkt werden kann. Der Riegel ist durch eine Schraube mit dem Rost lose verbunden. Dreht man die Schraube im anziehenden Sinne, wird zunächst der Riegel bis zum Anschlag in die Ausnehmungen eingeschwenkt und anschliessend gegen die Abdekkung verspannt, sodass die Abdeckung sicher auf der Rinne gehalten ist. Diese Vorrichtung hat sich sehr bewährt. Der Arbeitsaufwand zum Verriegeln und Lösen der Abdeckroste ist jedoch beträchtlich gross.A securing device for securing a cover grate on a drainage channel is known from EP patent 112 287. The channel has recesses on opposite side walls into which a bolt (locking bracket) can be swiveled in by turning. The bolt is loosely connected to the grate by a screw. If the screw is tightened, the bolt is first pivoted into the recesses as far as it will go and then clamped against the cover so that the cover is held securely on the channel. This device has proven very successful. However, the work involved in locking and releasing the cover grids is considerable.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung der eingangs genannten Art so auszubilden, dass der Arbeitsaufwand zum Verriegeln und Lösen der Abdeckung reduziert wird. Ferner sollen Toleranzen von Rinne, Abdeckung und Arretierung keinen Einfluss auf die Funktionstüchtigkeit haben.The present invention has for its object to design a device of the type mentioned in such a way that the work involved in locking and releasing the cover is reduced. Furthermore, tolerances of the gutter, cover and locking should not have any influence on the functionality.

In Figur 1 ist von einer Entwässerungsrinne 1 nur der obere Teil der beiden Seitenwände 2 dargestellt. Diese haben oben längs verlaufende Ausnehmungen 3 angeformt, oder die Ausnehmungen 3 sind mit Metall- oder Kunststoffprofilen ausgebildet, in welche eine Abdeckung, z.B. ein Rost 4 eingesetzt ist. Der Rost 4 hat seitlich zwei Längsrippen 5, die auf dem Grund der Ausnehmung 3 aufliegen. Durch Querrippen 6 sind die beiden Längsrippen 5 miteinander verbunden. Mindestens zwei der Querrippen 6 sind in der Mitte verdickt oder so ausgebildet, dass ein Durchgang mit Versenkung 7 zur Aufnahme eines Bolzenkopfes 8 eines Bolzens 9 entsteht. In der Querebene des Bolzens 9 sind in den Seitenwänden 2 auf gleicher Höhe je ein Riegelhaltekasten 10 aus Kunststoff angeformt oder eingelegt (wie z.B. in EP-B 112 287) mit inneren Ausnehmungen 11. In diese wird, durch Drehen des Bolzens 9 im Urzeigersinn in der Darstellung nach Figur 2, ein Riegel 12 eingefahren und anschliessend durch Weiterdrehen des Bolzens 9 gegen den Rost 4 verspannt. Der Riegel 12 besteht vorzugsweise aus rostbeständigem Federstahl. Er hat in der Mitte zwei nach unten gerichtete Stege 13. Die beiden Stege 13 bilden den Riegel im Bereich deren Länge a als nach unten offenes U-Profil aus. Somit wird der Riegel 12 im Bereich dieser Länge a biegesteif.In Figure 1 of a drainage channel 1, only the upper part of the two side walls 2 is shown. These have integrally formed longitudinally extending recesses 3, or the recesses 3 are formed with metal or plastic profiles, in which a cover, e.g. a grate 4 is inserted. The grate 4 has two longitudinal ribs 5 on the side, which rest on the bottom of the recess 3. The two longitudinal ribs 5 are connected to one another by transverse ribs 6. At least two of the transverse ribs 6 are thickened in the middle or are designed such that a passage with countersink 7 for receiving a bolt head 8 of a bolt 9 is created. In the transverse plane of the bolt 9, a bolt holding box 10 made of plastic is formed or inserted in the side walls 2 at the same height (as, for example, in EP-B 112 287) with internal recesses 11. This is turned by turning the bolt 9 clockwise into 2, a bolt 12 is retracted and then clamped against the grate 4 by turning the bolt 9 further. The latch 12 is preferably made of rust-resistant spring steel. It has two webs 13 pointing downwards in the middle. The two webs 13 form the bolt in the region of their length a as a U-profile which is open at the bottom. The bar 12 thus becomes rigid in the region of this length a.

In der Mitte des Riegels 12 wird von unten ein Spannelement 14 aufgeklipst. Das Spannelement 14 hat an der Unterseite einen zylindrischen Vorsprung 15 mit zwei zentralsymmetrischen, zur Achse 16 des Bolzens 9 wendelförmig ansteigenden Spannflächen 17. Die Spannflächen 17 können einstufig oder mehrstufig ausgebildet sein. Das Spannelement 14 ist an der Oberseite mit zwei Haltenocken 18 ausgestattet. Es wird mit diesen in Querschlitze 19' des Riegels 12 eingedrückt. Damit ist der Riegel 12 mit dem Spannelement 14 verbunden. Dieser zweiteilige Riegel hat den Vorteil, dass die Einzelteile in ganz unterschiedlichen Materialien hergestellt sein können, wie z.B. der Riegel 12 aus Federstahl und das Spannelement 14 aus abriebfestem Kunststoff.A clamping element 14 is clipped on from below in the middle of the latch 12. The clamping element 14 has on the underside a cylindrical projection 15 with two centrally symmetrical clamping surfaces 17 rising helically to the axis 16 of the bolt 9. The clamping surfaces 17 can be designed in one or more stages. The clamping element 14 is equipped with two holding cams 18 on the upper side. It is pressed with these into transverse slots 19 'of the bolt 12. The bolt 12 is thus connected to the tensioning element 14. This two-part bolt has the advantage that the individual parts can be produced in completely different materials, such as the bolt 12 made of spring steel and the tensioning element 14 made of abrasion-resistant plastic.

Bei ein- wie auch bei mehrstufiger Ausbildung der Spannflächen 17 werden Toleranzen und Massabweichungen längs der Achse 16 des Bolzens 9 aufgenommen. Die Arme des Riegels 12 wirken dabei als Federelemente 19. Auf eine wendelförmig ansteigende Spannfläche 17 folgt jeweils eine Stufe 20 mit eventuell geringerer, entgegengesetzter Steigung. Die unterste Stufe wird von einer Anschlagfläche 21 und die oberste Stufe mit einer Anschlagfläche 22 begrenzt. Ein durch den Schaft 23 gesteckter oder am Schaft 23 direkt angegossener Querstift 24 mit prismatischem oder rundem Querschnitt liegt an den Flächen 17, 20 an. Der Querstift 24 wird bei der Montage zusammen mit dem Schaft 23 durch eine Durchgangsbohrung 25 mit zwei Längsnuten 26 im Riegel 12 und im Spannelement 14 durchgesteckt. Die Längsnuten 26 sind an den Stellen grösster axialer Dicke des Spannelements 14 vorgesehen. Dadurch wird das Abfallen des Riegels 12 verhindert. Zusätzlich können am Schaft 23 des Bolzens 9 Haltenoppen 27 angebracht sein, wie dies in Figuren 14 und 15 dargestellt ist, welche ebenfalls das Abfallen des Riegels 12 vom Bolzen 9 verhindern. Damit kann die komplette Schnellarretierung wie eine konventionelle Rostarretierung mit dem Rost komplett vormontiert werden und auch "blind" angezogen werden.With one-stage as well as multi-stage design of the clamping surfaces 17, tolerances and dimensional deviations along the axis 16 of the bolt 9 are recorded. The arms of the bolt 12 act as spring elements 19. A helically rising clamping surface 17 is followed in each case by a step 20 with a possibly lower, opposite slope. The bottom step is delimited by a stop surface 21 and the top step by a stop surface 22. A transverse pin 24 with a prismatic or round cross section, which is inserted through the shaft 23 or directly cast on the shaft 23, bears against the surfaces 17, 20. The cross pin 24 is inserted during assembly together with the shaft 23 through a through hole 25 with two longitudinal grooves 26 in the bolt 12 and in the clamping element 14. The longitudinal grooves 26 are provided at the locations of greatest axial thickness of the tensioning element 14. This prevents the latch 12 from falling off. In addition, holding knobs 27 can be attached to the shaft 23 of the bolt 9, as shown in FIGS. 14 and 15, which likewise prevent the bolt 12 from falling off the bolt 9. This means that the complete quick lock can be completely pre-assembled with the grate like a conventional grate lock and can also be "blind" tightened.

Die zweite Ausführungsform nach Figuren 7-13 unterscheidet sich dadurch von der ersten, dass der Riegel 28 nicht oder nur teilweise federnd ausgebildet ist. Die Feder 29 wird als separates Element in die dafür vorgesehene Rechtecköffnung 30 des Riegels 28 eingeklinkt. Das Spannelement 31 ist im oberen Bereich so ausgebildet, dass es mit den Haltestegen 32 seitlich über die Feder 29 eingerastet werden kann. Durch die Verschmälerung 33 seitlich an der Feder 29 ist eine Verschiebung des eingerasteten Spannelementes 31 verhindert.The second embodiment according to FIGS. 7-13 differs from the first in that the bolt 28 is not or only partially resilient. The spring 29 is latched as a separate element into the rectangular opening 30 of the latch 28 provided for this purpose. The tensioning element 31 is designed in the upper area such that it can be snapped in laterally by means of the spring 29 with the holding webs 32. The narrowing 33 on the side of the spring 29 prevents displacement of the latched clamping element 31.

Beim Einsetzen des Rostes 4 ist der Riegel 12, 28 mit dem Bolzen 9 mit dem Rost 4 lose vormontiert. Der Querstift 24 ruht in tiefster Position oder hängt an den Haltenocken 27. Beim Drehen des Bolzens 9 am Bolzenkopf 8 wird der Riegel 12, 28 zunächst in Eingriff mit den Riegelhaltekasten 10 gebracht, bis die Flächen 33 des Riegels 12, 28 an den Anschlagflächen 34 der Riegelhaltekasten 10 anliegen. Beim Weiterdrehen gleitet der Querstift 24 auf der einen oder ersten Spannfläche 17, bis er auf der durch die Gegensteigung 20 verursachten Kerbe 35 einrastet. Je nach Toleranz kann der Bolzen 9 im mehrstufigen Spannelement 14 eine oder zwei Stufen weiter gedreht werden. Beim einstufigen Spannelement 14 wird die gesamte Steigung b mit dieser einen Stufe überbrückt und die Toleranzen werden allesamt durch das Federelement 19 am Riegel 12 bzw. durch die Feder 29 aufgenommen und ausgeglichen.When inserting the grate 4, the bolt 12, 28 with the bolt 9 with the grate 4 is loosely preassembled. The cross pin 24 rests in the lowest position or hangs on the holding cams 27. When the bolt 9 on the bolt head 8 is turned, the bolt 12, 28 is first brought into engagement with the bolt holding box 10 until the surfaces 33 of the bolt 12, 28 on the stop surfaces 34 the bolt holding box 10 concerns. When turning further, the transverse pin 24 slides on one or the first clamping surface 17 until it engages on the notch 35 caused by the counter pitch 20. Depending on the tolerance, the bolt 9 in the multi-stage clamping element 14 can be rotated one or two stages further. In the case of the single-stage tensioning element 14, the entire pitch b is bridged by this one stage and the tolerances are all taken up and compensated for by the spring element 19 on the bolt 12 or by the spring 29.

Beim Lösen der Sicherung wird der Bolzen 9 im umgekehrten Sinne gedreht, bis der Querstift 24 an der Anschlagfläche 21 ansteht, worauf der Riegel 12, 28 durch die nun formschlüssige Verbindung zwangsweise mitgedreht wird. Der Riegel 12, 28 wird somit wieder aus den Riegelhaltekasten ausgedreht und der Rost 4 kann abgehoben werden. Durch die Haltnoppen 27 am Schaft 23 des Bolzens 9 bleibt die Sicherung am Rost 4 vormontiert. Zum Spannen und Lösen braucht der Bolzen 9 nur 1/4 bis 1/2 Umdrehungen. Dadurch ist die Montage und Demontage des Rostes 4 besonders zeitsparend gegenüber andern konventionellen Systemen. Durch die zwangsweise Mitnahme des Riegels 12, 28 ist das Lösen und Spannen sehr zuverlässig.
Um ein sicheres Einfahren des Riegels 12, 28 in die Riegelhaltekasten 10 zu gewährleisten, kann der Riegel 12, 28 an der Oberseite auch stirnseitige Rundungen 36 und Schrägflächen 37 aufweisen.When the fuse is released, the bolt 9 is rotated in the opposite direction until the transverse pin 24 abuts the stop surface 21, whereupon the bolt 12, 28 is also rotated by the now positive connection. The bolt 12, 28 is thus unscrewed again from the bolt holding box and the grate 4 can be lifted off. Due to the retaining knobs 27 on the shaft 23 of the bolt 9, the fuse on the grate 4 remains preassembled. The bolt 9 only needs 1/4 to 1/2 turns to tighten and loosen. As a result, the assembly and disassembly of the grate 4 is particularly time-saving compared to other conventional systems. Due to the forced entrainment of the bolt 12, 28, the loosening and tensioning is very reliable.
In order to ensure that the bolt 12, 28 is securely retracted into the bolt holding box 10, the bolt 12, 28 can also have end curves 36 and inclined surfaces 37 on the upper side.

Die Längsnuten 26 im Riegel 12 und im Spannelement 14, 31 können auch weggelassen werden, wenn der Querstift 24 in entsprechende Durchgangslöcher des Schaftes 23 des Bolzens 9 eingesetzt wird. In diesem Falle kann eine Unterlagsscheibe 38 über den Schaft 23 geschoben werden. Sind die Querstifte 24 fest angegossen, muss die Scheibe 38 ebenfalls am Bolzenkopf 8 angegossen sein.The longitudinal grooves 26 in the bolt 12 and in the clamping element 14, 31 can also be omitted if the cross pin 24 is inserted into corresponding through holes in the shaft 23 of the bolt 9. In this case, a washer 38 can be pushed over the shaft 23. If the cross pins 24 are firmly cast on, the washer 38 must also be cast on the bolt head 8.

Bei der Ausführungsform nach Fig. 16 und 17 besteht der Riegel 12 aus Kunststoff. Der Vorsprung 15 des Spannelementes 14 ist einstückig an den Riegel 12 angegossen. Der Riegel 12 ist eben und hat beidseits des Vorsprungs 15 je eine rechteckige Vertiefung 45. In den Riegel 12 sind zwei längsverlaufende, nahezu bis zu den Riegelenden reichende, federelastische Stäbe 46 vorzugsweise aus Federstahl eingegossen, welche an den Enden rechtwinklig abgekröpft sind. Alternativ können die beiden Stäbe 46 auch einstückig als U-förmiger Stab mit abgekröpften Enden ausgebildet werden. Die Abkröpfungen 47 verhindern eine Längsverschiebung der Stäbe 46 im Kunststoffkörper. Die Stäbe 46 können einen rechteckigen oder runden Querschnitt haben. Die Verankerung in Längsrichtung kann auch durch andere Verankerungsmittel als die Abkröpfungen 47 erzielt werden, z.B. durch Querbohrungen. Die federelastische Armierung kann auch als flache oder gebogene Platte ausgebildet sein.In the embodiment according to FIGS. 16 and 17, the latch 12 is made of plastic. The projection 15 of the clamping element 14 is integrally cast onto the bolt 12. The latch 12 is flat and has a rectangular recess 45 on each side of the projection 15. In the bolt 12, two longitudinally extending, almost to the bolt ends, resilient rods 46 are preferably cast from spring steel, which are bent at right angles at the ends. Alternatively, the two rods 46 can also be formed in one piece as a U-shaped rod with bent ends. The bent portions 47 prevent the rods 46 from being displaced longitudinally in the plastic body. The bars 46 can have a rectangular or round cross section. The anchoring in the longitudinal direction can also be achieved by anchoring means other than the elbows 47, for example by transverse bores. The resilient reinforcement can also be designed as a flat or curved plate.
