ABSTRACT:

BACKGROUND OF THE INVENTION
INCORPORATION BY REFERENCE
Applicant(s) hereby incorporate herein by reference, any and all U.S. patents, U.S. patent applications, and other documents and printed matter cited or referred to in this application.
FIELD OF THE INVENTION
This invention relates generally to crown molding and indirect lighting systems and more particularly to a plaster molding adapted for indirect lighting and a method for installation.
DESCRIPTION OF RELATED ART
The following art defines the present state of this field:
Minidis, U.S. D424,709 describes a cove base design.
Richter, U.S. Pat. No. 1,249,500 describes the combination of interior illumination with the walls of a room, of a removably light confining trough involving a supporting body structure designed to contact with and be securely fastened to the said walls, the lower portion of said body having provided with a ledge; suitable brace members secured to said body above the ledge; a radially disposed member consisting the exposed wall of the trough, which radial member is supported by the said brace members and aforesaid ledge; and lighting means concealed from view with the trough.
Goodhouse, U.S. Pat. No. 1,780,125 describes a fixture for indirect illumination, a moulding strip including a fixed section constituting a supporting and reflecting means for the source of illumination and a movable section for protecting and concealing the source of illumination and interengageable means of connection provided respectively on said sections, said fixed section having a strenghening flange projecting outwardly therefrom and disposed at an angle with an outer portion of the movable section with which it engages for strengthening and supporting purposes.
McCutcheon, U.S. Pat. No. 1,917,139 describes a new article of manufacture, a base tile comprising an upright body having its lower portion provided with a downwardly inclined lateral extension the end of which is formed with a transverse rabbet extending the entire width of the tile and opening through the top and front face of said extension to provide an open seat for floor surfacing material and an abutment at the end of the extension for engagement with a floor substructure, the walls of the rabbet being disposed at substantially right angles to each other and defining upper and lower straight edges, one of which indicates the level of the floor surfacing material and the other the level of the floor substructure.
Filsinger, U.S. Pat. No. 3,309,832 describes a ceramic trim element adapted for multi-purpose use in wail structures employing a plurality of ceramic tile assembled in a pattern, comprising: a ceramic body member including: a main body portion of uniform width having a front glazed surface, a glazed edge face, and a back unglazed surface; said main body portion having adjacent said glazed edge face a longitudinal edge section of reduced thickness providing a longitudinally extending front surface recess; and a leg portion projecting from the back surface of the main body portion at the edge opposite the reduced edge section and generally normal thereto, said leg portion having uniform width for the length of the main body portion and having an outer glazed surface merging with the outer glazed surface of the main body portion, a glazed edge face and a sloping unglazed back face merging with the back unglazed surface of the main body portion.
Roberts, U.S. Pat. No. 4,600,975 describes an indirect lighting assembly consisting of a housing structure and low voltage light tubing for retention therein, said housing structure being a unitarily extruded body having an anchor tab portion extending perpendicularly into a spacer portion and terminating in a light tube housing portion having an open area directing light generally perpendicular to the plane of said spacer portion.
Azzar et al., U.S. Pat. No. 5,157,886 describes an extruded, thermoplastic baseboard elastomeric molding strip having opposed generally flat front and rear surfaces is provided with a plurality of closely vertically, spaced horizontal, parallel ribs projecting outwardly of the flat front surface over the full surface area thereof. The strip is formed of front and rear surface layers of thermoplastic material of the same durometer hardness with the front surface layer forming at least the tips of the front surface ribs being of a low density thermoplastic material and the balance of the strip being of high density thermoplastic material. The front and rear surface layers may be of contrasting colors. The rear surface of the strip is preferably formed with concave grooves separated by a multiplicity of fine, vertically spaced horizontal, parallel rearwardly projecting ribs with a rear, center rib between adjacent fine ribs, of a larger diameter than adjacent fine ribs separating the rear surface grooves. The rear surface configuration facilitates removing of excess wet adhesive and maintenance of flush adhesive mounting of the molding strip to a building vertical wall.
Juntunen, U.S. Pat. No. 5,199,237 describes a decorative receptacle covering and providing the appearance of a finished joint between the adjacent rough cut ends of two lineal moldings. The receptacle slidably receives the ends of the lineal moldings, covers the ends and allows cutting the moldings to a rough length and rough end cut, thereby reducing or eliminating the need for precision carpentry skills by one installing the moldings. Receptacles can be made for a wide variety of decorative moldings including casing moldings, base moldings, chair rail moldings, and crown moldings.
Kanarek, U.S. Pat. No. 5,226,724 describes a modular, fluorescent, indirect lighting system which may be easily mounted to most surfaces by the user, without any technical knowledge or experience, using just a screwdriver and measuring tape. The system is comprised of a family of plug-in modules, each of which contain an integral power bus, that provides power continuity to the adjacent module, and a gender conversion plug that allows the installer to configure each module so that power is supplied only from female connectors. The system includes a power source module and three sizes of illumination modules, which house single 20, 30 or 40 watt lamps, as well as inside and outside corner modules and both straight and corner adjustable-length modules. Modules selected from this family can be plugged together to create a cove lighting system for a room of almost any size or shape. The complete installation is powered by a neat line cord plugged into a standard wall outlet. And, each module can accommodate a continuous decorative facing strip that both enhances the appearance and conceals the modular nature of the system.
Singhal, U.S. Pat. No. 5,287,667 describes a tile for waterproofing the juncture of a tiled surface and a non tiled surface such as a tub and tile juncture by use of a water proof tile. The waterproof tile consists of a glazed tile surface having a curvature which directs the water away from the juncture, a non glazed surface which is cemented to the tiled wall and a bottom side which holds sealant for sealing against the non tiled surface.
Fulton, U.S. Pat. No. 5,359,817 describes trim moldings such as crown molding, chair rail molding, base molding and door casing for a building. The trim moldings are made of substantially acrylic or polyester rigid thermoset polymer components. The trim moldings may be manufactured to realistically visually simulate moldings made of natural stone. A method of manufacture of the moldings may utilizes bulk slabs or blocks of rigid thermoset polymer based materials which are then properly shaped for use as a building trim molding with mechanical material removal methods such as sawing, cutting, sanding, and polishing to achieve the desired size, shape and appearance of molding. The thermoset polymer based moldings are structured with grooves in the backside, with the grooves sized and positioned to snap onto spring biased members of mounting fixtures attached to the building for a removable atta
