Abstract (en)

[origin: EP0668409A1] The grating fits into a frame (3) set in the rod, and has end bars (4) which are elastically deformable relative to the other bars (1,2) so that the grating is fitted elastically in the frame. The deformable end bar is connected to the remainder of the grating only by its two ends, between which it has a lug to engage with a notch (7) in the frame; it also has two thrust elements (9) which can interact with the frame and the adjacent bar (1) of the grating. The grating can be made with a deformable bar at each end and a series of parallel main bars between them, joined to the end bars by two transverse bars (2).
