DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring now to the drawings, and particularly to FIGS. 1–3, a preferred embodiment of the rainfall simulation apparatus of the present invention is shown and generally designated by the reference numeral 10.
In FIG. 1, a new and improved rainfall simulation apparatus 10 of the present invention for providing the relaxing acoustic effect of rainfall on a structure while additionally providing the visual effect of rainfall through the windows of the structure is illustrated and will be described. More particularly, the rainfall simulation apparatus 10 comprises a water source 30, an electric pump 12 connected to the water source 30, a vertically oriented riser pipe 14 connected to the pump 12, a structure 26 next to the riser pipe 14 with the structure 26 comprising a roof 28 connected to substantially vertical walls, a header pipe 16 connected to the riser pipe 14 and along the roof 28 with the header pipe 16 defining a plurality of perforations 18 therein through which water 32 can flow to simulate rainfall, a V-shaped trough 20 connected to the roof 28 with the trough 20 defining a plurality of apertures therein through which water 32 can flow to simulate rainfall, and at least one elongated collection bin 24 below the trough 20 and connected to the pump 12, wherein water 32 pumped through the riser pipe 14 and the header pipe 16 exits the perforations 18 and flows down the roof 28 into the trough 20, drops thorough the apertures into the collection bin 24, and flows back to the pump 12. A vertically rising structure 34 is attached to the sidewall of the header pipe 16 and prevents water 32 from flowing down the portion of the roof that does not have a trough 20 and collection bin 24 beneath it.
FIG. 2 is an enlarged side elevational cross-sectional view of the trough 20 of the rainfall simulation apparatus of the present invention, and illustrates the trough 20 connected to the roof 28. The bottom of the trough 20 has apertures 22 through which water can flow to simulate rainfall.
FIG. 3 is an enlarged front elevational view of the header pipe 16 of the rainfall simulation apparatus of the present invention, and illustrates the header pipe 16 having perforations 18 through which water can flow to simulate rainfall.
The rainfall simulation apparatus of the present invention is a system that provides a simulated rainfall effect on the exterior of a sunroom, atrium, or related glazed area. In one embodiment, the unit comprises a suitably large electric pump. Its outlet is linked to a riser pipe that extends up one end of the atrium or related structure in question. Its upper end is linked to a header pipe that extends the length of the roof of this structure. Its upper surface features a series of small perforations in order to provide an even, diffuse level of distribution. In a preferred embodiment, these perforations comprise adjustable water nozzles with diameters of about 1/16 inch to about 3⁄4 inch, with a spacing of about 3 inches to about 6 inches between perforations. The pump is supplied via an outside water source and one or more plastic, elongated, collection bins that are routed along the lower outside perimeter of the structure. They preferably feature an overflow portion to permit excess water to be channeled into a dry well, French drain, etc. In order to provide the requisite rainfall effect outside of the windows of the structure, the usual gutter is replaced with a special trough. This features a V-shaped cross-section, with a flange on one side that permits it to be fastened to the lower edge of the roof of the structure. In one embodiment, small holes extend through the bottom of the trough, and in another embodiment, its lower portion features a series of approximately 2 inch to approximately 4 inch wide apertures, or gaps.
The roof of the structure may comprise steel, galvanized steel, tile, glass, transparent plastic, or any other suitable material. The pipes may comprise steel, copper, plastic such as PVC, or any other suitable material. The trough and collection bins may comprise aluminum, plastic, or other suitable material. If steel is used, it is preferably painted to prevent rusting.
The rainfall simulation apparatus of the present invention fulfills the need for a simulated rainfall effect on the exterior of an atrium, sunroom, or related structure. The appealing features of the rainfall simulation apparatus include its unobtrusive appearance, ease of operation, and the realistic effect it provides. The small size and low profile of the components of this system endow it with a visually unobtrusive appearance when not in use. Operation involves merely turning on the unit's pump. This initiates a rainfall-like effect on the roof of such a structure, thereby producing the familiar, relaxing acoustic signature of this type of event. By channeling the runoff along the length of the structure, the trough portion provides the visual effect of rain through the windows of the structure. The water is then collected in the unit's tanks and is re-circulated, thus continuing the relaxing, stress-reducing rainfall effect.
In one embodiment, the rainfall simulation apparatus of the present invention comprises a waterfall apparatus in operable association with an atrium, wherein the waterfall is formed from an elongated V-shaped trough apparatus having a plurality of offset apertures extending therethrough for creating a unique waterfall arrangement.
In use, it can now be understood that the rainfall simulation apparatus of the present invention has particular utility in connection with providing the relaxing acoustic effect of rainfall on a structure while additionally providing the visual effect of rainfall through the windows of the structure.
While a preferred embodiment of the rainfall simulation apparatus has been described in detail, it should be apparent that modifications and variations thereto are possible, all of which fall within the true spirit and scope of the invention. With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention. For example, any suitable sturdy material such as any metal, plastic, or composite material may be used instead of the materials described. Also, the pump may be powered by kerosene, natural gas, or any known type of power rather than electricity. And although providing the relaxing acoustic effect of rainfall on a structure while additionally providing the visual effect of rainfall through the windows of the structure has been described, it should be appreciated that the rainfall simulation apparatus herein described is also suitable for irrigating an atrium or related structure, and simulating the effect of a rainforest. Furthermore, a wide variety of different pipe configurations may be used for structures with different roof shapes instead of those described.
Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
