  • Patent number: 6729747
    Abstract: The invention is directed to a combination lampshade assembly. The assembly consists of a base lampshade with a closed outer surface, with an upper opening and lower opening and a generally uniform closed surface area between them. The base lampshade assembly has no visible connecting devices or means which would differentiate it from the outward appearance of a standard lampshade. The base lampshade may be of opaque, transparent or translucent material. A rigid outer lampshade assembly is configured to fit over the standard lampshade base assembly and is held in place gravitationally by contact between the base assembly and the outer assembly. The outer assembly may be in two interchangeable pieces, with an inner sheath, and an outer cover with cut-out designs on its surface.
