Brief Patent Description - Full Patent Description - Patent Application Claims
BACKGROUND OF THE INVENTION [0001] a) Field of the Invention [0002] This concept relates generally to the field of furnishings and more particularly to furniture objects such as tables, chairs, fountains, coffee tables, patio tables, wall furnishings, and other items which occur within the human living environment. More particularly, this concept relates to providing an ornamental flame as a centerpiece within the furnishing object. The operation and control of the flame as it appears above noncombustible media such as water, rocks, glass, sand, and other material which is noncombustible is provided within this general concept. [0003] b) Background Art [0004] The following prior art discusses various forms of burner assemblies but it is believed that they in no way disclose the present concept. [0005] U.S. Pat. No. 6,926,517 discloses an apparatus and method for simulated campfires which has a fire pan, a diffuser element located within the pan, and a gas injector which extends into the interior. Referring to column 2 at line 47, the campfire apparatus can be assembled on a support surface and connected to a fuel source. A fire pan which has a main body with an inner surface and an upper rim holds the vaporized fuel when the gas is injected through a gas outlet into the pan interior. A vaporized fuel diffuser helps to disperse the fuel into the pan. Low density, nonflammable, material is disbursed in the pan to a depth sufficient to cover the gas fuel injector and the diffuser element. The particulate material allows the fuel vapor to pass upwards and restricts ignition of the fuel until the fuel reaches the upper surface of the particulate material. The particulate matter as discussed in column 3 around line 6, is selected from a group of materials such as silicates, carbonates, course sands, ores, and material such as vermiculite. [0006] U.S. Pat. No. 6,769,906 discloses a fire effect appliance which has a bowl which is supplied by a flammable gas line. A defusing device is also included and evenly distributes the gas throughout particulate matter contained within the inner chamber of the fire bowl. The bowl can be placed on a freestanding mount, or placed within a table. A fan as seen in FIG. 4 is positioned below the heating element and is provided to force the heat upwards and disperse the heat into the adjacent environment. Referring to column 2 at line 61, the fire bowl is in the range of 18 to 14 inches in diameter. The bowl has an upper edge which has an annular flat flange and mounted on the undersurface of the flange are a plurality of pegs which act as feet to be placed against the table. Referring to column 3 at line 5, the table has a centrally located hole in one embodiment and because the fire bowl will become quite heated, the fire bowl pegs keep the bowl separated from the table so the table does not burn. The fire bowl itself is constructed of steel or aluminum. A defusing plate as seen in column 3 at line 37 is basically a flat circular metallic plate constructed of steel. The plate is proportional in diameter to the fire bowl diameter. The plate ranges in diameter from 57-60% of the largest diameter of the fire bowl. Particulate matter is also placed within the fire bowl such as gravel or any other type of particulate that is capable of being heated. [0007] U.S. Pat. No. 6,609,514 discloses a portable fire pit and fire pit stand which has an elevated platform, fire pit within the platform, and a container of fuel. A decorative item may be placed within the fire pit and around the fuel. The fuel is ignited to display a large flame. A cover is placed over the fire pit. Referring to column 3 at line 25, a flange is formed around the top perimeter of the fire pit and allows the pit portion to be inserted and retained in the elevated platform without need of fastening. A container grate as seen in column 3 around line 36 is placed in the bottom of the fire pit, which reduces heat transfer from the heating element to the bottom of the pit. Further down at line 42, at least one container of fuel is surrounded by a decorative item which mimics for example, a noncombustible log, coals, stones or other items. The fuel is in one form a gel or in another form a type of alcohol fuel derivative. [0008] U.S. Pat. No. 6,354,288 discloses a portable fireplace which has an inner housing and a flame pit. An outer housing surrounds the inner housing and a space is formed between the inner and outer housings to create an insulation zone. A support is contained within the flame pit to hold a flame presentation substance. Referring to column 3 at line 5, a fire ring which has a series of interconnected tubes forming a manifold has perforations and allows gas to be fed to the fire ring to exit and be ignited by a suitable ignition source. Contained over the fire ring as discussed in column 3 at line 48, is the flame presentation substance such as wood, log, rocks, artificial logs, and other similar ornamental looking devices. [0009] U.S. Pat. No. 6,192,881 discloses a portable fireplace with a planar base and a plurality of gas orifices. The base can be any shape, and the gas is directed through channels to orifices where it emerges and ignites. In an alternative embodiment, the base is enclosed within a tight wind screen and contains water which allows the illusion of flames emerging from a flame burning water surface. Referring to column 3 at line 40, it is possible to add rocks to the base in order to enhance the visual effect. Also, the fluid as discussed in line 59 may also comprise any noncombustible fluid. Once the gas emerges from the water, the gas is ignited by a match or spark igniter, and the flame gives an enjoyable visual effect in a sustained manner above the surface of the fluid. When used with the fluid, the orifices discharging the gas also use a diaphragm valve or check valve to prevent the water or fluid from entering into the gas channel. [0010] U.S. Pat. No. 6,065,466 discloses a barbecue and patio table combination with a burner pit positioned in the upper section of the table which can be covered when not in use by a lid which is flush with the upper surface of the table slab. Cooking griddle, charcoal plate, and ash collecting bucket are held within the inner wall of the burner pit in an inverted frusto conical shape. [0011] U.S. Pat. No. 5,868,128 discloses a fire pit which has controls for flames from a lava rock media visibly displayed at the base portion of an elevated platform. Surrounding the platform is a wall to contain the lava rocks. A gas line which has a number of outlet ports disposed throughout the lava rocks is contained herein. Attached to the base portion is a lid support structure which is substantially open around the lateral sides above the wall, which allows clear view of the law for rocks within the base portion. A controlled fire may be safely displayed in any outdoor space including residential areas of urban and suburban locales. [0012] U.S. Pat. No. 5,168,796 discloses a combination table and cooking grill, which has a horizontal tabletop and a centrally disposed aperture in the middle of the table where the tabletop is mounted on the upper portion of a vertical hollow pedestal. An inner grill housing houses the heat source and the cooking grate with the grate and the heat source positioned below or in line with the central aperture. Users can place food items around the periphery of the table and grill the barbecued food as desired. [0013] U.S. Pat. No. 3,582,250 discloses a gas fire fireplace basket which simulates a coal fire and incorporates a plurality of gas burners beneath the screen which in turn supports a plurality of pieces of noncombustible material in a loosely disposed shallow layer. A deepened pocket in the screen locates pieces of noncombustible material adjacent cutaway areas in the front portion of the basket which provides for the illusion of greater depth of the noncombustible materials than is actually provided. [0014] U.S. Pat. No. 3,565,337 discloses a flaming fountain, which is a display device where natural or other combustible gases mixed with water as the water is ejected from a special mixing chamber and causes the gas to be trapped and encapsulated with air bubbles suspended in the water stream so that when a mixture of gaseous and water breaks over a loss of momentum and gravity, the bubbles break, releasing the combustible gas which is ignited and provides a flame at the point where the water breaks over. By varying the pressure of the water, the encapsulated gas may be released at selected heights and over greater various areas.
