Abstract
The top (1) comprises a frame (2) applied on the outline of an opening (20) realised on the ground (3). A lid (4) is connected to the frame by hinges (5) suitable for the opening and the closing of the lid. Each of the hinges comprises a pivot (6) which is located into a hollow (7) of the frame and which is received in a seat (8) realised in a protrusion (9) belonging to the lid suitable for coupling with the hollow. The hollow provides a first fixed striker (10) that during the opening of the lid contrast with the protrusion and realise the lifting of the lid by sliding the seat against the pivot. The striker releases the contact against the protrusion allowing its penetration towards the bottom of the hollow by the lowering of the lid when this is arranged in opened position is order to realise the contact of the protrusion against a second striker suitable for preventing the closing of the lid by simple rotation about the hinge.
