Abstract

A tray ceiling for drop ceilings and method of manufacture and installation therefor, wherein a selected area of foam panels and associated intersecting and supporting T-bars of a drop ceiling are removed to form an open area or clearing bordered by a perimeter of T-bars, thereby enabling a suitably dimensioned tray ceiling of simple and light-weight construction to be received, seated, and supported on the perimeter of T-bars, and wherein the tray ceiling is sufficiently structured to support the weight of conventional light fixtures and/or ceiling fan assemblies recessedly mounted therewithin.

Description

TECHNICAL FIELD

The present invention relates generally to tray ceilings, and more specifically to a tray ceiling for drop ceilings and method of manufacture and installation therefor. The present invention is particularly applicable to, although not strictly limited to, installation within a room having a low-level drop ceiling, thereby facilitating the recessed mounting of light fixtures and/or ceiling fan assemblies therewithin.

BACKGROUND OF THE INVENTION

Drop ceilings are often installed within office buildings, finished residential basements and/or academic buildings in lieu of conventional sheetrock ceilings for variety of purposes, such as expediency and efficiency in completion of building projects, budgetary limitations, effectively and economically masking duct work, electrical work, pipe work, or ceiling supports, and/or providing expeditious access to same.
Even in view of such recognizable benefits, however, drop ceilings noticeably lack the aesthetic appeal commonly associated with painted sheetrock ceilings, smooth ceilings, stucco or plaster ceilings, and/or similar finished fixed ceilings. Moreover, in view of the strong joist-and-beam support structure of traditional fixed ceilings, builders will often incorporate a tray ceiling within the fixed ceiling, thereby enhancing the overall visual depth and aesthetic appeal of same, while providing increased overhead room for recessed mounting of light fixtures and ceiling fan assemblies therewithin. Unfortunately however, although the typical heavy wooden frame and sheetrock assembly of many such tray ceilings is ideal for installation within, and anchoring to, the support structures of fixed ceilings, the structurally weaker arrangement or lattice assembly of T-bars and foam panels associated with traditional drop ceilings simply cannot effectively support such an installation. Accordingly, builders or homeowners seeking to install a tray ceiling within a drop ceiling will often remove the drop ceiling and resort to the application of additional ceiling support structures and sheetrock to build-in or create a tray ceiling—a process that imparts significant materials and labor costs unto the building owner.
Therefore, it is readily apparent that there is a need for a tray ceiling for drop ceilings and method of manufacture and installation therefor, wherein a builder and/or homeowner may expeditiously and relatively effortlessly install a light-weight tray ceiling within a drop ceiling without application of additional support structures and/or sheetrock for anchoring the tray ceiling to joists, beams, and/or other ceiling support structures. There is a further need for a tray ceiling for installation within a drop ceiling, wherein the tray ceiling is sufficiently structured to support the weight of conventional light fixtures and/or ceiling fan assemblies recessedly mounted therewithin.

BRIEF SUMMARY OF THE INVENTION

Briefly described, in a preferred embodiment, the present invention overcomes the above-mentioned disadvantages and meets the recognized need for such a device by providing a tray ceiling for drop ceilings and method of manufacture and installation therefor, wherein a selected area of foam panels and associated intersecting and supporting T-bars of a drop ceiling are removed to form an open area or clearing bordered by a perimeter of T-bars, thereby enabling a suitably dimensioned tray ceiling of simple and light-weight construction to be received, seated, and supported on the perimeter of T-bars, and wherein the tray ceiling is sufficiently structured to support the weight of conventional light fixtures and/or ceiling fan assemblies recessedly mounted therewithin.
According to its major aspects and broadly stated, the present invention in its preferred form is a tray ceiling for drop ceilings and method of manufacture and installation therefor, wherein the tray ceiling comprises a light-weight frame and sheet construction, and wherein the tray ceiling is suitably dimensioned to be received, seated, and supported on a perimeter of T-bars of a conventional drop ceiling.
More specifically, the present invention is a tray ceiling for drop ceilings and method of manufacture and installation therefor, wherein the tray ceiling is preferably manufactured from a light-weight wooden frame comprising a series of wooden triangular-shaped supports and a centrally-disposed support brace, wherein appropriately sized and light-weight wooden sheets, panels, or sections are affixed to the frame to form the tray ceiling. Installation of the completed tray ceiling preferably entails the removal of a selected area of foam panels and associated intersecting and supporting T-bars from a pre-existing, or newly installed, drop ceiling, thereby forming an open area or clearing bordered by a perimeter of T-bars, wherein the perimeter of T-bars is preferably suitably dimensioned to receive the tray ceiling. Thereafter, the tray ceiling is inserted into the open area defined by the perimeter or border of T-bars, and seated and supported on the T-bars, wherein suitable clamps, braces, set screws, or the like, may also be utilized to securely retain the mounting position of the installed tray ceiling. The present tray ceiling further comprises a centrally-disposed throughhole formed through the centrally-disposed support brace of the frame, and extending through the overlying Birchwood section, wherein electrical wires may be selectively channeled or drawn therethrough for the electrical engagement of same to a light fixture or ceiling fan assembly recessedly mounted to the tray ceiling (i.e., to the centrally-disposed support brace).
In an alternate embodiment of the present invention, it is contemplated that the tray ceiling could be formed as a single molded unit via blow-molding, vacuum forming and/or extrusion processes, wherein suitable light-weight plastics, polyvinyl chloride, cellulose materials, or the like, could be utilized as the substrate for forming such a tray ceiling. In another alternate embodiment of the present invention, it is contemplated that the tray ceiling could be formed as a plurality of cooperatively engageable or snap-fit panels, segments and/or sheets, wherein suitable light-weight plastics, polyvinyl chloride, cellulose materials, or the like, could be utilized as the substrate for forming such a tray ceiling.
Accordingly, a feature and advantage of the present invention is its ability to provide a tray ceiling for drop ceilings without application of additional support structures and/or sheetrock for anchoring the tray ceiling to joists, beams, and/or other ceiling support structures.
Another feature and advantage of the present invention is its ability to enable a builder and/or homeowner to expeditiously and relatively effortlessly install a light-weight tray ceiling within a drop ceiling.
Still another feature and advantage of the present invention is its ability to provide a tray ceiling for installation within a drop ceiling, wherein the tray ceiling is sufficiently structured to support the weight of conventional light fixtures and/or ceiling fan assemblies recessedly mounted therewithin.
Still yet another feature and advantage of the present invention is its light-weight construction and framework.
A further feature and advantage of the present invention is its ability to provide the aesthetic qualities commonly associated with traditional sheet rock tray ceilings, but without the weight typically associated therewith.
Still another further feature and advantage of the present invention is its ability to enable the recessed mounting of light fixtures and/or ceiling fan assemblies in rooms comprising relatively low-level drop ceilings.
Still yet another feature and advantage of the present invention is its ability to be shaped and/or dimensioned to yield double tray ceilings, hexagonally-shaped tray ceilings, octagonally-shaped tray ceilings, square-shaped tray ceilings, rectangularly-shaped tray ceilings, or circularly-shaped or ovally-shaped tray ceilings (i.e., with the optional addition of suitable trim and/or molding).
Still yet another and further feature and advantage of the present invention is its ability to incorporate recessed can lighting fixtures for providing a light source flush with the tray ceiling surface.
These and other features and advantages of the present invention will become more apparent to one skilled in the art from the following description and claims when read in light of the accompanying drawings.
