CA 2372784

The invention concerns a road network device comprising a frame and an element (14) for covering the frame, the frame (12) comprising a peripheral rim with a double wall defining a groove and the covering element being provided with a protruding peripheral lip engaged in the groove in a position covering the frame. The covering element (14) comprises at least a ramp (44) extending between the lip and said element inner surface, the ramp(s) being arranged to be supported on the terminal edge of the frame peripheral rim, thereby providing a means for guiding covering element when the latter is moved relative to the frame, by the action of a force exerted on said element in a zone opposite to the ramp(s) (44).

Ce dispositif de voirie comprend un cadre et un élément (14) de recouvrement du cadre, le cadre (12) comportant un bord périphérique à double paroi délimitant une gorge et l'élément de recouvrement étant doté d'une lèvre périphérique en saillie s'engageant dans la gorge en position de recouvrement du cadre. L'élément (14) de recouvrement comporte au moins une rampe (44) s'étendant entre la lèvre et la surface interne dudit élément, la ou les rampes étant destinées à s'appuyer sur la tranche d'extrémité du bord périphérique du cadre et constituant ainsi un moyen de guidage de l'élément de recouvrement lors du déplacement de celui-ci par rapport au cadre, sous l'action d'un effort exercé sur ledit élément dans une zone opposée à la ou les rampes (44).
