- The term “portable” is used herein to refer to a fire pit that is not permanently installed, and that can be readily transported as a single unit to another location by one or two persons, as opposed to a permanent installation or formed of materials and in such a way that it cannot be moved by one or two persons or without damaging it.
- As illustrated in
FIGS. 1a -5, a portable combination fuel fire pit, indicated generally at 10, in an example implementation in accordance with the invention is shown. The fire pit can be readily portable and can burn or utilize multiple fuel sources or combinations of fuel, including by way of example, wood and briquettes (or the like) and gas (such as propane). Thus, the fire pit can avoid fouling of a gas burner by ash, soot and/or embers from burning wood or briquettes. In addition, the fire pit can utilize one fuel, such as propane, to ignite another fuel, such as wood or briquettes. Furthermore, the fire pit can provide a unique visual affect with silhouettes of outdoor themes, such as an animal (e.g. horse, deer, elk, etc.), a person (e.g. cowboy, etc.), a landscape (e.g. mountain range, fenced range, etc.), or combinations thereof (e.g. bull rider on a bull, cowboy leaning on a fence, etc.). - The
fire pit 10 comprises afire bowl 14 elevated on apedestal 18 and having anopen top 22. Thefire bowl 14 can have a concave indentation, and theopen top 22 can face upwardly. The fire bowl can receive fuel on or in the fire bowl. In one aspect, thefire bowl 14 can be formed of metal, and can have a rectilinear (square or rectangular) shape with fourperimeter side walls 26. In addition, the fire bowl can have abottom wall 30 formed by two angled halves, that can be flat, meeting at a valley (or lowest point in a middle thereof). Anopening 34 can be formed in the bottom wall through which ash can pass. Furthermore, the fire bowl can have anannular flange 38 oriented horizontally and circumscribing theside walls 26 at or near an upper end of the side walls. In one aspect, theannular flange 38 can be flush with an upper end of the side walls. Thus, ash can be conveniently swept from the annular flange into the bowl and out the opening. In one aspect, the upper end of the side walls and theannular flange 38 can define a top of the fire bowl, and theopen top 22 of the fire bowl. In another aspect, theannular flange 38 can extend radially outwardly beyond a spark screen (described below) to form aguard 40 around the fire bowl, and/or to define or receive handles. Thepedestal 18 can also be formed of metal. In one aspect, thepedestal 18 can comprise a plurality of legs or feet to support the fire bowl above a support surface (i.e. the ground, a floor, etc.). The pedestal can be formed of separate legs, or can have a single continuous leg. One or more openings can be formed in the pedestal for air circulation, cooling, an ash tray, etc. - A
spark screen 42 is disposed over thefire bowl 14, and encloses theopen top 22 of the fire bowl. In one aspect, thespark screen 42 can be disposed on and/or carried by theannular flange 38 of the fire bowl. In one aspect, thespark screen 42 can have a cylindrical shape with a vertical side wall(s) 46 and anenclosed top 50. In one aspect, the cylindrical shape of the spark screen can be circular, as shown. In one aspect, the spark screen can be affixed to the fire bowl, such as by welding so that the spark screen, fire bowl and pedestal for a single integral unit. In another aspect, the spark screen can be separable from the fire bowl. The spark screen and vertical side wall can define a fuel receiving area and/or flame area. A majority of the flame from the burning fuel can be located in the spark screen, and above the fire bowl. The vertical side wall(s) 46 of the spark screen can extend above, and can be located above, thefire bowl 14. Thus, the flames can be visible through the spark screen. - The vertical side wall(s) 46 of the
spark screen 42 can have at least two sections (or different types of sections), including: a solid section(s) 54 and a mesh section(s) 58. The mesh section(s) 58 can be formed of or can comprise mesh to allow heat and smoke to escape, while resisting sparks and or embers from escaping. The solid section(s) 54 can be more solid with respect to the mesh section, as described below. In addition, the vertical side wall(s) 46 of thespark screen 42 can comprising at least amesh layer 62, and agraphic layer 66, with one inside the other, and with one overlapping the other. Themesh layer 62 can form the mesh section(s) 58, while thegraphic layer 66 can form the solid section(s) 54. Both the mesh layer and the graphic layer can be cylindrical. The mesh layer can be a continuous cylinder of mesh, while the graphic layer can be a discontinuous cylinder of solid sections. In one aspect, the mesh layer can be an interior layer while the graphic layer can be an exterior layer. Thus, the graphic layer, which can be more rigid, can provide form to the mesh layer. In another aspect, graphic layer can be interior while the mesh layer can be exterior. Thus, the mesh layer, which can have greater heat dissipation, can act as an exterior guard to the graphic layer. The graphic and mesh layers 66 and 62 together form the vertical side wall(s), and enclose a lateral side of the spark screen. In addition, the solid andmesh sections mesh sections - A grating 70 is disposed across the
open top 22 of thefire bowl 14, and between the fire bowl and thespark screen 42. The grating 70 can be disposed on and carried by theannular flange 38 and/or the upper end of theside walls 26. The fuel, such as thewood 106 and/or thebriquettes 110, can be disposed on the grating, and inside the spark screen. The wood and/or briquettes can burn on top of the grating, whileash 114 from the burning wood and/or briquettes can fall through the grating and into the fire bowl, and then through the opening. The grating can be formed of metal and can be rigid. - A
gas burner 74 is disposed in thefire bowl 14 and below the grating 70 and over theopening 34. Thegas burner 74 can have anopen cup 78 facing upwardly and aneck 82 extending laterally from the open cup. The gas burner can be formed of cast iron. Theopen cup 78 of the gas burner can have acup wall 86 with an upper edge that is open around an entire perimeter of the open cup. An insert 90 can be disposed in theopen cup 78 below the upper edge. The insert can have a saw-tooth perimeter defining a plurality of gas ports between the saw-tooth perimeter of the insert and an interior of the cup. Thebase burner 74 or neck thereof can be coupled to a gas line 94 (that can extend into the fire bowl) to supply the base burner with fuel, such as propane or natural gas. The gas line can extend to agas port 118 carried by the pedestal, and which can be coupled to a propane tank, or other gas source, such as a natural gas line. - The fire pit has a
cover plate 98 disposed over thegas burner 74, and spaced above the gas burner. Thecover plate 98 can be sized and positioned to cover theopen cup 78 and neck 82 (andgas line 94 if extending into the fire bowl) of the gas burner from above. Thus, thecover plate 98 can have an enlarged portion with a substantially circular shape to match and cover theopen cup 78, and a narrower portion with an elongated shape to match and cover the neck (and gas line). Thecover plate 98 can extend from a perimeter of thefire bowl 14, and can be cantilevered from the perimeter of the fire bowl and out over theopen cup 78 of thegas burner 74. Thus, the cover plate can cover the entire gas burner, which is disposed over the opening. In one aspect, asupport brace 100 can extend (perpendicular to the cover plate) between a bottom of thecover plate 98 and theside wall 26 of thefire bowl 14 to resist deflection of the cover plate towards the burner. Thecover plate 98 can be disposed immediately below the grating 70, and can abut to the bottom of the grating 70, and the cover plate 98 (or upper surface thereof) can be flush with the open top 22 (or upper surface of theannular flange 38 or upper edge of the side wall 26) offire bowl 14. Thus, the gas burner can be located adjacent the wood or briquettes and utilized to ignite the wood or briquettes. A gap is formed between the burner 74 (oropen cup 78 thereof) and thecover plate 98, and can be defined between a portion of the open cup and a portion of a perimeter of the cover plate. In one aspect, the cap can be arc shaped, and can substantially circumscribe the open cup; and is thus substantially arcuate or a substantially arcuate gap. In one aspect, a majority of a perimeter edge of thecover plate 98 can match a shape of theopen cup 78 of thegas burner 74. Thus, the cover plate or enlarged portion thereof can be circular. Thecover plate 98, or enlarged portion thereof, can be sized slightly larger than theopen cup 78 of thegas burner 74 to form a lip or overhang extending out over theopen cup 78 of the gas burner to resist entry of soot or ash into the open cup, and thus resist fouling of the gas ports. In addition, the cover plate, or lip thereof, can direct the flame from the gas ports and open cup radially outwardly, to enlarge or expand the flame. Thus, the cover plate can have a substantially similar shape to the gas burner, but a larger size. In another aspect, a perimeter shape or lip of thecover plate 98 can be supplemented to have a wavy shape or wavy profile or wavy perimeter with alternating indentations and protrusions, as shown. Thus, the cover plate or lip thereof can direct flame from the gas ports and open cup radially outwardly different amounts, or different distances, to give the flame greater depth. - One or
more support posts 102 can extend from thefire bowl 14 to the grating 70, and/or to a level substantially flush with theopen top 22 of the fire bowl. The post(s) 102 can abut an intermediate portion of the grating 70 so that the grating is supported by the post(s). In one aspect, theposts 102 can be disposed around theopening 34, such as at the corners thereof, to maximize support. Theposts 102 can have enlarged heads to avoid passing through opening in thegrating 70. - In use, the
fire pit 10 can be capable of receiving burningwood 106 orbriquettes 110 on the grating 70, and thecover plate 98 can be capable of shielding theopen cup 78 of thegas burner 74 from fallingash 114 or soot (or the like, such as embers, or smaller parts of burning wood or briquette) from the burning wood or briquettes. Thus, thecover plate 98 resists fouling of the gas ports in theopen cup 78 of thegas burner 74. In addition, thegas burner 74 can be capable of receiving gas and burning the gas in theopen cup 78, and thecover plate 98 can be capable of directing flames from the burning gas radially outwardly around a perimeter of the cover plate. Thus, thefire pit 10 can be used for both wood (or briquettes) and gas. - As indicated above, the
gas line 94 can extend from theneck 82 of thegas burner 74, (through thefire bowl 14 in one aspect), out one of theperimeter side walls 26 of the fire bowl 14 (such as through an aperture in the perimeter side wall at the valley), and to aport 118 or fitting for coupling to a gas line to a gas source (such as a propane bottle or tank). Theport 118 or fitting can be disposed in and carried by thepedestal 18. The gas line can include valves and/or pressure regulators. In addition, the fire pit can have a gas igniter with a switch carried by the pedestal, and a sparker disposed adjacent the outlet ports and/or open cup. - A user can select to use gas and/or wood or briquettes. The user can connect a gas source (such as a propane bottle or tank) to the
gas burner 74, such as by coupling the gas line to theport 118 of the fire pit. The gas can be ignited manually, such as with a match or lighter; or the user can press the switch to activate the sparker. Thecover plate 98 can direct the flame from the gas ports andopen cup 78 radially outwardly, to enlarge or expand the flame. In addition, the user can placewood 106 orbriquettes 110 in thespark screen 42 and on thegrating 70. The wood or briquettes can be ignited manually, such as with a match or lighter; or the user can utilize thegas burner 74 to ignite the wood or briquettes. Thecover plate 98 resists fallingash 114 or soot (or the like, such as embers, or smaller parts of burning wood or briquette) from the burning wood or briquettes from fouling the gas ports or theopen cup 78 of thegas burner 74. - The falling ash or soot, and embers, from the burning wood or briquettes, can accumulate in the
bottom wall 30 of thefire bowl 14, and pass through theopening 34 into anash tray 120. Theash tray 120 can be removably disposed on a shelf 124 under thefire bowl 14 andopening 34 to facilitate disposal of the ash and soot. - In one aspect, the
spark screen 42 can provide unique and aesthetically appealing visual effects along with the flame produced in by the fire pit. As described above, thespark screen 42 can have a cylindrical shape with vertical side wall(s) 46 and anenclosed top 50. The vertical side wall(s) 46 of thespark screen 42 can extend above thefire bowl 14 for visibility. The vertical side wall(s) 46 of thespark screen 42 can comprise at least two sections (or at least two different sections), including: a solid section(s) 54 and a mesh section(s) 58, which together form the vertical side wall and enclosing a lateral side of the spark screen. Themesh section 58 can be formed of or can comprise mesh to allow heat and smoke to escape, while resisting sparks and or embers from escaping. In one aspect, the mesh sections can be formed of woven wire. Themesh sections 58 can have openings therein greater in size or diameter than the diameter or width of the wire or solid portions thereof. Thesolid sections 54 can be more solid (than the mesh sections) and can have a greater surface area with respect to the mesh section. Thesolid sections 54 can have solid portions with a width or size greater than the size or diameter of the openings in the mesh sections. - In addition, the vertical side wall(s) 46 of the
spark screen 42 can comprising at least amesh layer 62, and agraphic layer 66, with one inside the other, and with one overlapping the other. Thegraphic layer 66 can comprise solid section(s) 54 and open section(s) (filled with the mesh sections 58). In one aspect, themesh layer 62 can be an interior layer while thegraphic layer 66 can be an exterior layer. Thus, thegraphic layer 66, which can be more rigid, can provide form to themesh layer 62. In another aspect, graphic layer can be interior while the mesh layer can be exterior. Thus, the mesh layer, which can have greater heat dissipation, can act as a guard to the graphic layer. The graphic and mesh layers 66 and 62 together form the vertical side wall(s) 46, and enclose a lateral side of thespark screen 42. In addition, the solid andmesh sections spark screen 46. The graphic and mesh layers 66 and 62 together can have or can form the solid andmesh sections solid sections 54 can have interior andexterior perimeters stencil 130. In one aspect, the silhouette or stencil can have multiple mesh or open sections, and thus multiple interior perimeters. The silhouette orstencil 130 can define an object comprising at least: an animal (e.g. horse, deer, elk, or portion thereof, etc.), a person (e.g. cowboy, etc.), a landscape (e.g. mountain range, fenced range, etc.), or combinations thereof (e.g. bull rider on a bull, cowboy leaning on a fence, etc.). The silhouette or stencil can also include other thematic elements (e.g. saddle, etc.). The silhouette orstencil 130 can be back-lit by the flame. Thus, in addition to the flame, the silhouette orstencil 130 can provide a unique and aesthetically appealing visual effect. - In addition, the enclosed top 50 can include solid sections and mesh section, and a mesh layer and a graphic layer, as described above. In one aspect, the enclosed top 50 can also include a silhouette or stencil, as described above.
- In one aspect, the
spark screen 42 can be cylindrical or circular, as shown inFIG. 1a . The circular shape of the spark screen can allow for a continuous silhouette or stencil, and thus a continuous image. In one aspect, thefire pit 10 can be circular and large (having a height substantially the same as a width), as shown inFIG. 1a . In another aspect, thefire pit 10 b can have a spark screen that is circular and smaller (having a height greater than a width, or a height greater than twice the width), as shown inFIGS. 6a and 6b . In another aspect, thefire pit 10 c can have a spark screen that is rectilinear (square or rectangular) or a polygon, with multiple sides, such as hexagonal (as shown inFIGS. 7a and 7b ). The rectilinear or polygon shape can facilitate manufacture. In addition, the rectilinear or polygon shape of the spark screen can allow for multiple panels for multiple silhouettes or stencils, and thus multiple scenes. - Although the fire bowl has been described above as being rectilinear (square or rectangular), the fire bowl can have any shape. The rectilinear shape can facilitate manufacture. In one aspect, the fire bowl can be circular.
- In addition, the spark screen or silhouette or stencil can be formed in multiple panels that make up the spark screen or lateral wall thereof. One of the panels can be pivotally coupled to the spark screen to form an access door or panel to the spark screen, and facilitate the insertion of wood and/or briquettes.
