As a safety precaution against theft, the invention concerns a rigid cover (3) mounted articulated on a frame (1) and comprising two lateral edges (32A, 32B) bearing two pivots (30A, 30B) defining an axis of articulation parallel to an articulating ridge (31) of the cover and urged to be engaged into two cells (10) of the frame at least partly overhung by a wall (13) of said frame, said cover comprising an elastic finger (36) extending parallel to the lateral edges (32A, 32B); the free end of the finger is located proximate to the articulating ridge (31) and co-operates with a thrust pin (14) borne by the corresponding articulating edge (11) of the frame to enable, by elastic deformation of the finger (36) pressed against the pin (14), the pivots (30A, 30B) to be fixed in and removed from their respective cells (10). The invention is useful for covering vents of underground water distribution systems.
Pour sécuriser contre le vol un couvercle (3) rigide monté articulé sur un châssis (1) et comprenant deux bords latéraux (32A, 32B) portant deux tourillons (30A, 30B) définissant un axe d'articulation parallèle à une rive d'articulation (31) du couvercle et venant s'engager dans deux alvéoles (10) du châssis surplombées au moins partiellement par une paroi (13) de ce châssis, ce couvercle comporte un doigt (36) élastique s'étendant parallèlement aux bords latéraux (32A, 32B); l'extrémité libre du doigt est situées à proximité de la rive d'articulation (31) et coopère avec un ergot de poussée (14) porté par le bord d'articulation (11) correspondant du châssis pour permettre, par déformation élastique du doigt (36) en appui contre l'ergot (14), la mise en place des tourillons (30A, 30B) dans leurs alvéoles (10) respectives et leur retrait. Utilisation: recouvrement des cheminées des réseaux d'eau souterrains.
