Panels for the lighting of rooms or the like, with automatic rapid opening and comprising a plurality of simultaneously operated sections

摘要

This panel comprises a rigid support structure 2, or rafter, terminating in a frame of general square shape, extended by four crossmembers originating from the four corners of this frame and meeting at a common vertex 11 in order to form the edges of a regular pyramid, the faces A, B, C, D of which consist of four identical triangular sections, each section being bordered along its three sides by a metal profile supporting a sheet of transparent material. According to the invention, the part of the profile of each section extending along the corresponding side of the frame is fixed to an angle piece carrying hinges mounted on said side to allow the panel to pivot about this, a jack 13 fixed to the rigid support structure 2 being arranged in the axis of the pyramid and comprising a rod 14, on which are articulated links 16-17 connected to the sections of the panel. <IMAGE>
