Title:
CURVED PANEL
Document Type and Number:
WIPO Patent Application WO/1992/012378
Kind Code:
A1
Abstract:
A curved panel in which various shapes of a curved surface can easily be obtained only by curving the body proper of the panel and by fixing reinforcing plates thereto. An object of this curved panel is to provide such various effects as: size reduction in the working equipment; adaptability to a variety of specifications; cut in manufacturing cost; and more refined shape of the curved surface. For attaining the object, the curved panel is provided with deformed and bent pieces to permit bending of a surface plate and to be formed on two opposing sides of the surface plate capable of elastic deformation, and reinforcing bent pieces are formed on the other opposing two sides for keeping these two sides straight. On the other hand, reinforcing plates are formed to be smaller in curvature than said specified surface. Reinforcing plates are fixed to the forcedly curved pieces of the panel proper so that elastic shape-keeping force by which the panel proper tends to be restored to a flat surface may be balanced with elastic shape-keeping force of the reinforcing plate in order to provide a specified curved surface.
