Abstract (en)
The invention concerns a perfected gully and manhole top (1; 100; 201) for zones where the circulation is permitted to pedestrians and vehicles comprising: a frame (2; 520; 202) applied on the outline of an opening (20) realized on the ground (3);and a lid (4; 54; 204; 240) connected to said frame (2; 520; 202) by one or more hinges (5; 50; 205; 250; 350). There are first fixed striker means (10; 510; 200) that during the opening of said lid (4; 54; 204; 240) contrast with said protrusion (9; 59; 209) and realize the lifting up of said lid. Said first striker means (10; 510; 200) release the contact against said protrusion (9; 59; 209) allowing the lowering according to the gravity of said lid (4; 54; 204; 240) when this is arranged in opened position with an angle (16) greater than 90 DEG in order to realise the contact of said protrusion (9; 59; 209) against second striker means (72; 73; 51) suitable for preventing the closing of said lid (4; 54; 204; 240) by simple rotation around said hinge (5; 50; 205; 250; 350). <IMAGE>
