ABSTRACT:
A rigidified, conical structure formed of pleated or finely fluted material, having particular application to a lampshade. It includes a lampshade body which is formed of a tube of the pleated material which is radially collapsed at one end giving the tube a frustoconical shape. An outer shell of small diameter fits around the exterior surface of the collapsed end of the lampshade body, and an inner shell of larger diameter fits against the inner surface thereof. The two shells are drawn toward each other by a bolt and the lampshade body is clamped to the surface contours of the shells to become rigidified and to give the lampshade a cone angle which is determined by the shape of the shells.
