ABSTRACT:
A false ceiling comprises a stretched sheet made of a relatively elastic material which is hooked, along its edges, to a horizontal support frame constituted by abutting sections, fixed to the walls of a room. Above the sheet, i.e. in the space between this sheet and the ceiling of the room, means exert on the sheet at at least one point thereof, an adjustable effort provoking a deformation of the sheet. These means comprise a cable passing over a pulley fixed to the ceiling of the room, of which the vertical side acts, at its lower end, on the sheet, in order to exert thereon the adjustable vertical effort, and of which the other inclined or manoeuvring side is hooked on the wall, above the support frame, on this support frame itself or on the ceiling.
