Abstract (en)
[origin: EP0506591A1] The device comprises a frame (1) and a removable grating (2) which is hinged along an axis X-X of the frame, which grating consists of a series of bars connected in pairs, by at least one tie and running perpendicularly to the hinge axis X-X of the grating (2). The grating (2) furthermore comprises two intermediate bars (19A, 19B) connected to the other bars of the grating by their ends opposite the hinge axis X-X and the free ends of which interact, by elastic bending of the bars (19A, 19B) in the plane of the grating, with means (13, 14), arranged on the frame (1), for holding the grating (2) in the open and closed position. <IMAGE>
