Abstract

The grating (1) comprises a frame (2) with a support surface (6) and on the periphery a ratchet point (8). A removable rigid cover (3) on the support surface has a springy bar (15) whose free end (16), located on the cover edge, mates with the ratchet point. The springy bar forms an angle of 60 degrees with the adjacent periphery of the cover, while its free end is framed by the rigid cover edge (12). The ratchet point and the free end of the bar each have a double ramp for locking and unlocking. The cover has a slot (18) in a location spaced from the bar, for the introduction of a tool for tipping the cover about a peripheral zone parallel to the bar. <IMAGE>
