FIELD OF THE INVENTION
The present invention relates to leak diverters, and more particularly to leak diverters for positioning above suspended ceilings.
BACKGROUND OF THE INVENTION
Many commercial, public, and private buildings are constructed to include a suspended ceiling, also known as a drop ceiling. A suspended ceiling comprises an interconnected support grid and removable ceiling panels, such as acoustic tiles, positioned within the support grid. Support wires can be used to support the suspended ceiling from a structural building ceiling or roof. The tiles are typically 24×24 inches or 24×48 inches, however, other sized may also be used. The use of a suspended ceiling creates a functional hidden space between the structural ceiling, such as the underside of the roof or intermediate floors, and the suspended ceiling, which is observable from the interior of a room. This hidden space is often utilized for the installation of sprinkler systems, fire and smoke warning systems, computer networking, electrical cables and conduits, heating, ventilating and cooling (HVAC) systems, and/or water piping systems. Normal usage of the above-mentioned elements, as well as openings in the building roof, faulty plumbing and/or condensation that forms on piping and/or HVAC system components, can result in the formation of leaks. Without a leak diverting device, leaks can contact the ceiling panels causing structural damage, discoloration and/or unwanted moisture. In certain situations, leaks can pass through the ceiling panels and drip onto the contents of the room interior.
Previous attempts to confine leaks have included systems placed within the interior of the room and positioned underneath a leaking ceiling tile, such as floor mounted structures comprising a telescoping pole and a collection bag positioned along the underside of a ceiling panel. Other leak confinement systems have included ceiling tiles designed to collect leakage. Examples of such tiles are disclosed in U.S. Pat. Nos. 6,640,502 and 5,008,652. Although such designs may effectively handle many types of leaks, the tiles are visible from the interior of the room, must fit within the support grid, typically comprise visible hoses, and do not usually have the same appearance as conventional tiles or panels. Conventional deigns cannot be positioned along the perimeter of the ceiling, i.e. along cut ceiling tiles, and do not catch leaks that occur on the perimeter of the ceiling, such as leaks that occur above the grid itself.
There exists a need for a leak diverter that may be positioned above suspended ceilings that is inexpensive to produce, installs quickly, does not require a substantial retrofit to the existing suspended ceiling, and blends aesthetically with the occupied space below the suspended ceiling.
SUMMARY OF THE INVENTION
The present invention is a leak diverter that includes a liquid collection tray structured and arranged to rest above a suspended ceiling and a drain in flow communication with the liquid collection tray. The liquid collection tray can be supported by a perimeter frame and/or a plurality of support members. The liquid collection tray can also comprise a side barrier for confining liquid within the tray. A drain may be positioned to extend through either the bottom or side of the liquid collection tray. A drain hose is typically connected to the drain, however, it will be appreciated herein that the leak diverter of the present invention can be used without a drain hose.
It is an object of the present invention to provide a leak diverter for positioning above a suspended ceiling comprising a liquid collection tray structured and arranged to rest above the suspended ceiling, and a drain in flow communication with the liquid collection tray.
It is a further object of the present invention to provide a leak diverter for positioning above a suspended ceiling comprising a liquid collection tray and a drain in flow communication with the liquid collection tray, wherein the drain is structured and arranged to be positioned above the suspended ceiling.
A further objective of the present invention is to provide a leak diverting system comprising a suspended ceiling having an upper surface, and a leak diverter resting on the upper surface of the suspended ceiling.
It is yet a further objective of the present invention to provide a leak diverting system comprising a suspended ceiling, a liquid collection tray, and a drain in flow communication with liquid collection tray and positioned above the suspended ceiling.
These and other aspects of the present invention will be more apparent from the following description.

DETAILED DESCRIPTION
FIGS. 1-4 illustrate a leak diverter in accordance with an embodiment of the present invention. As shown in FIG. 1, the leak diverter 10 is structured and arranged to rest above a suspended ceiling 16. As used herein the term “suspended ceiling,” means a ceiling installed below the structural ceiling or roof of a building and observable from inside the building. An example of a suspended ceiling is shown in FIG. 1 comprising an interlocking support grid 18 and removable ceiling panels 20, such as acoustic tiles, positionable within the support grid 18. The support grid 18 may be suspended from the structural ceiling and/or sidewalls of a building frame by support wires, and the support grid 18 can comprise a plurality of horizontal and/or vertical support bars, such as a plurality of horizontal and vertical support bars intersecting at right angles. The structural ceiling can comprise the substantially horizontal support system demarcating a story in a multiple story building, or the flat or angled interior of a building roof. The suspended ceiling 16 typically comprises a finished lower surface structured to face into a room interior and be visible to occupants of the room, and an upper surface which faces the structural ceiling. The leak diverter 10 of the present invention, is structured and arranged to rest above the suspended ceiling 16, i.e., on top of the upper surface of the ceiling panels 20 or support grid 18, or suspended from the structural ceiling, such as from support wires and/or metal trusses or pipes.
Referring to FIGS. 1 and 2, the leak diverter 10 in accordance with an embodiment of the present invention comprises a liquid collection tray in the form of a flexible plastic sheet 12 and a drain 14 in fluid communication with the flexible sheet 12. As used herein, the term “liquid collection tray” means any suitable arrangement for collecting liquid, such as roof leaks, water leaking from piping and/or condensation and the like, which could otherwise fall onto the upper surface of the suspended ceiling 16. The liquid collection tray can comprise a rigid, semi-rigid and/or flexible sheet of material or preformed container. The flexible sheet and/or preformed container can comprise a polymeric material and/or a metal composition coated to prevent rust and/or corrosion. The liquid collection tray can comprise any suitable shape and size, such as a substantially square or rectangular shape. In one embodiment, the liquid collection tray may be sized differently than the size of a ceiling panel 20. For example, the liquid collection tray may be smaller in at least one dimension than the standard 24×24 inch or 24×48 inch ceiling panel, or may be larger in at least one dimension than such panels.
