This invention relates to the field of decorative structural treatments for a wall of a building, and more particularly to a crown for use over windows and doors, and to methods of making such crowns.
BACKGROUND OF THE INVENTIONEspecially in modern construction buildings, windows and doors are often a simple opening, or a frame mounted around the window or door.
Such a construction is not always visually adequate for the owner of the building. Frequently, the owner of a building will try to enhance the appearance of a window by hanging a simple or elaborate curtain assembly, but this seems to be temporary, and not a part of the architecture of the building.
A number of types of cornices or other enhancements of window or door construction have been proposed, such as that shown in U.S. Design Pat. No. 393,771. However, such systems have two drawbacks, generally. First, the cornice is a box that tends to block light from the window or door, making the room darker and without improving the light in the room in any way. Second, the manufacture of such cornices requires a somewhat complex fabrication procedure, making them relatively costly.
SUMMARY OF THE INVENTIONIt is accordingly an object of the present invention to provide a window or door crown assembly that overcomes the limitations of prior art designs. It is also an object of the invention to provide a method of economically fabricating such an assembly.
According to the invention, an architectural assembly comprises a wall of a building having an opening therein through which light passes, and a cover structure is supported on the wall over a top portion of the opening. The cover structure has a light transmission portion permitting light from the opening to pass therethrough.
According to another aspect of the invention, a crown structure is provided for mounting over an opening, such as a door or a window, in a building. The crown structure supports a transparent or translucent material that allows light from the window or door opening to pass through, and preferably tints the light to produce a backlit color that can be seen inside the room.
According to a preferred embodiment of the invention, the cornice box comprises a lower cornice member and an upper cornice member, and a transparent or translucent, preferably glass, panel is secured between the cornice members using a silicone or other adhesive material. Preferably the upper and lower cornice members each have a groove therein that receives the adhesive and the glass, and a top panel cover structure.
It is further an object of the invention to provide for a process of manufacturing a cornice that comprises cutting a portion of molding material so as to yield two side portions and a front portion. The stock material has a milled portion defining a continuous groove therein and the cutting including at least two matching miter cuts. The side portions and the front portion are assembled so as to form a box structure in which the groove extends continuously. Panels of light transmissive material are secured in the groove so as to project away from the box structure.
According to another aspect of the invention, a method of forming a cornice comprises forming a top crown frame box by miter cutting three members with a miter cut from milled stock, or analogously formed stock having a continuous or repeating cross section, so that the three members are assembled into an upper cornice frame box having a downwardly disposed engagement recess, and forming a lower cornice frame box by miter cutting three members from other milled stock, or analogously-formed stock having a continuous or repeating cross section, and assembling them into a frame. Panels of transmissive material are then secured between the upper and lower cornice frames and the cornice is then mounted over a top portion of the opening in a wall of a building so as to permit light to pass through the light-transmissive material.
Other objects and advantages of the invention will become apparent from the foregoing disclosure, and the scope of the invention will be expressed in the claims.

According to an aspect of the invention, a method of fabricating the cover structure is also provided. In this method, upper structure 13 is fabricated by cutting a length of material so as to form the box structure of 13. The material is miter-cut twice at appropriate angles to form the middle portion 21 of the box structure, and twice to form the corner engagement parts of the side portions 17 and 19. The angles are such that, viewed from above, the portions 17 and 19 meet center portion 21 at a 45° angle. The actual angle relative to the perpendicular plane to a flat side of the material varies dependent on the upward angle of outward extension of the side portions 17 and 19 and the center portion 21 that causes the box structure to flare upwardly. In addition to those miter-cuts, the wall-engaging portions of the side members 17 and 19 are cut perpendicular to the material to yield ends 23 and 25 that engage the planar surface of wall 5 flushly, with no space therebetween. The material used is preferably a molding material or milled material having a constant cross section, or a repeating pattern in its cross section, such that the miter-cuts can be made and the parts 17, 19 and 21 be joined at the corners of the box structure 13 so that the cross sections meet without exposing any ends of the cut portions. The assembly of the portions 17, 19 and 21 is accomplished with typical securement methods, preferably finishing nails and/or adhesive.
The lower portion 11 is preferably prepared in a similar way by cutting a length of milled or constant cross-section material with two 45° miter cuts to form middle portion that allow the assembly of the box structure of the lower portion 11 and a perpendicular abutment and facing the wall.
Once the box structure 13 and the lower structure 11 are fabricated, the glass or other transparent or translucent part of the light transmitting structure 9 is secured therein by adhesive 63 and 67, as best seen in
Once the top structure 13, light transmitting portion 9, and the lower structure 1 1 are secured together, this assembly is then secured to the wall using support brackets 27 with at least one on each side of the covering structure 1. After attachment of the covering structure 1 to the wall, the top portion 15 is placed thereon to complete the installation.
The lower box structure 111 is similarly configured of three different miter-cut sections of constant cross-section milled material, all of which have a groove therein secured to the lower end of the transparent or translucent light transmitting structure 113. The top structure 115 also uses a material of a different constant cross section for the outer rail 117 thereof as well.
Different cross-section materials are used for the lower portion 127, which is provided by miter-cutting three members 128, 129 and 130 and assembling them into a box, which is supported below a light transmitting structure 131 extending downward from the upper box structure 125 and supported thereon.
An advantage of the covering structures of the present invention is that the structures can be added to existing buildings that have relatively simple structure so as to impart the appearance of more complex and decorative architectural elements that traditionally are part of the original construction of the house, such as a window casement or a door frame with detailed molding.
In an alternate application, a covering structure as disclosed herein, instead of being mounted over a window or door, may be mounted to a wall of a building as a mantel or a shelf. Where the structure, such as the structure of
Where the top covering is used in a situation where there is no light or not much light to pass through the light-transmissive portion of the covering structure, such as use as a mantel or as a shelf that does not overlie a light source, then preferably electric lighting is installed inside the structure so as to backlight the light transmissive material, enhancing the appearance of the covering structure.
The terms used herein should be understood to be terms of description instead of terms of limitation, as those of skill in the art with this disclosure before them will be able to make changes and modifications therein without departing from the spirit of the invention.
