BACKGROUND OF THE INVENTION The present invention relates to fire pits and in particular an outdoor fire pit having a visual effect provided by fire and heating provided by infrared heaters.
Outdoor features are often provided at vacation and recreation areas to create a congenial atmosphere for guests, vacationers, and visitors to relax together. A fire pit is a particular attractive outdoor feature at winter vacation areas and resorts because the fire provides a visually inviting ambience and the heat given off by the fire provides welcome warmth in a cold climate. Fire pits are also enjoyed in costal areas where cool breezes are common. Unfortunately with increasing energy costs, it is very expensive to use an open fire as a heat source.
BRIEF SUMMARY OF THE INVENTION The present invention addresses the above and other needs by providing an outdoor feature which combines a fire feature producing a visual effect with infrared heaters providing heat. The fire feature resides centrally in a framework and at a height providing a visual attraction. The infrared heaters are attached to the framework and provide an efficient heat source for comfort for visitors. The infrared heaters may be positioned below the fire pit to warm the, feet of the visitors, and/or may be positioned above the fire pit to provide a more general coverage. The framework is constructed of a weather and corrosion resistant material to maintain appearance and to reduce maintenance.
In accordance with one aspect of the invention, there is provided an outdoor feature including vertical supports, a hearth supported by the vertical supports, and a fire feature approximately centered on the hearth. Lower infrared (IR) heaters reside under the hearth and directing heat downward to warm a visitor's feet.
In accordance with another aspect of the invention, there is provided an outdoor feature including vertical supports, a hearth supported by the vertical supports, and a fire feature approximately centered on the hearth. Upper infrared (IR) heaters reside above the hearth and directing heat downward to warm a visitor's feet. A roof may attached to the vertical supports, and the upper IR heaters may be attached to the roof or to the vertical supports.

DETAILED DESCRIPTION OF THE INVENTION The following description is of the best mode presently contemplated for carrying out the invention. This description is not to be taken in a limiting sense, but is made merely for the purpose of describing one or more preferred embodiments of the invention. The scope of the invention should be determined with reference to the claims.
A top view of anoutdoor feature10 according to the present invention is shown inFIG. 1A, and a front view of theoutdoor feature10 is shown inFIG. 1B. Theoutdoor feature10 includesvertical supports12, ahearth24 supported by thevertical supports12, and aroof20 supported by thevertical supports12. Theoutdoor feature10 resides on asurface28. The vertical supports12 preferably comprise a pair of spaced apart metal plates, and more preferably a pair of corrosive resistant spaced apart metal plates, or may be concrete columns, however, local construction codes and environmental considerations generally dictate size and material used for structures. Thevertical supports12 may be constructed from any material suitable for outdoor use, and may be columns, or any structure with sufficient strength to safely support thehearth24 and theroof20. Vertical support fill22 comprising an architecturally suitable material may be used to fills the gap between the spaced apartvertical supports12, and/orIR heaters30b(seeFIG. 3) may reside between the spaced apartvertical supports12.
Theroof20 preferably resides onbeams14 attached to thevertical supports12, and preferably has acentral opening24. Theroof20 and opening24 may be round, hexagonal, octagonal, or of any shape suitable for covering an outdoor feature. Theroof20 is preferably made from corrosion resistant material which are consistent with local building codes.
Thehearth24 has askirt26 for enclosing heating elements and/or fire feature elements. Thehearth24 preferably is made from stone, metal, concrete, a composite, or similar material. The top surface is preferably between two feet and 4 feet above thesurface28, and the lowest point of the skirt is preferably between 12 inches and 36 inches above thesurface28.
A top view of a structure supporting theroof20 of theoutdoor feature10 is shown inFIG. 2. The structure includes thebeams14,inner trusses16, andouter trusses18. Any structure suitable for attaching to the vertical supports12 (seeFIG. 1B) and for supporting theroof20 may be used. The IR heaters may comprise first upper infrared (IR)heaters30awhich are attached under theroof20 and direct radiant head downwards towards visitors. TheIR heaters30amay be attached to thebeams14, to the underside of theroof20, or to thetrusses16 or18 and theIR heaters30aare preferably approximately four feet long. The number IR ofheaters30aor the size of theheaters30amay be increased or decreased as desired to provide more or less heat to visitors, and the number ofIR heaters30aon at a particular time may be varied as needed. The IR heaters may also comprise second upper Infrared (IR)heaters30battached to thevertical supports12 as shown inFIG. 3.
A side view ofradiant heat34afrom theUpper IR heaters30a(seeFIG. 2) mounted under theroof20 is shown inFIG. 4A, and a top view of theradiant heat34ais shown inFIG. 4B. Theradiant heat34ais directed downward toward visitors.
A side view ofradiant heat34bfrom theUpper IR heaters30bmounted to thevertical supports12 is shown inFIG. 4C, and a top view of theradiant heat34bis shown inFIG. 4D. EachIR heater30bdirects heat towards visitors on a side of theoutdoor feature10 opposite thevertical support12 which theIR heater30ais mounted to.
A perspective view of thehearth24 with afirst skirt18aof theoutdoor feature10 is shown inFIG. 5, a side view of thehearth24 of theoutdoor feature10 is shown inFIG. 6, and a cross-sectional view of thehearth24 taken alongline6A-6A ofFIG. 6 is shown inFIG. 6A. Theskirt18ais approximately cylindrical and a firstlower IR heater30cresided in theskirt18aand directs a thirdradiant heat34cdownward and outward. Theradiant heat34cthus directed provides warmth to the feet of visitors. Afire pit32 resides centrally in thehearth24.
A side view of thehearth24 with asecond skirt18bof theoutdoor feature10 is shown inFIG. 7, and a cross-sectional view of thehearth24 taken alongline7A-7A ofFIG. 7 is shown inFIG. 7A. Theskirt18bincludes angledsides36 covering secondlower IR heaters30d. TheIR heaters30dare tilted to provide a fourthradiant heat34dangled downward and outward to provide warmth to the feet of visitors.
TheIR heaters30a,30b,30c, and30dare preferably electric IR heaters, or gas IR heaters, and are more preferably natural gas or propane IR heaters. TheIR heater30a(seeFIG. 2) preferably generates between approximately 60,000 BTU's and approximately 120,000 BTU's of heat each. TheIR heater30b(seeFIG. 3) preferably generates between approximately 120,000 BTU's and approximately 240,000 BTU's of heat each. TheIR heaters30cand30d(seeFIGS. 6A and 7A) preferably generate a total of between approximately 100,000 BTU's and approximately 130,000 BTU's of heat. The fire feature preferably generates between approximately 125,000 BTU's and approximately 150,000 BTU's of heat and preferably a solid fuel (e.g., wood) or a gas (e.g., natural gas or propane) fire.
While examples IR heaters and fire features have been described above, an outdoor feature with any type of IR heater providing warmth and any visual effect providing a fire feature is intended to come within the scope of the present invention.
While the invention herein disclosed has been described by means of specific embodiments and applications thereof, numerous modifications and variations could be made thereto by those skilled in the art without departing from the scope of the invention set forth in the claims.
