Description

CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims the benefit of U.S. Provisional Application No. 63/563,933, filed Mar. 11, 2024, the disclosure of which is hereby incorporated by reference herein in its entirety.

TECHNICAL FIELD

The present invention relates generally to fire pit systems, and, more specifically, the present invention relates to a portable smokeless fire pit system for outdoor use.

BACKGROUND

Being outdoors has increased in popularity, whether it is camping, fishing, or just being in the backyard. Many outdoor activities call for a fire pit to keep warm or just for further enjoyment. Fires allow for a large group to sit and enjoy the warmth and beauty of the fire. However, fires also provide smoke and often the smoke does not travel straight upwards from the fire and, as such, it sometimes becomes necessary to move seating positions due to the path of the smoke around the fire. This can occasionally become annoying.

Fire pits can be built into the ground or can be above ground. Some above ground fire pits are bowl type fire pits that can be used on the backyard patio and may be light enough to facilitate portability. One type of portable, bowl like fire pit, includes structure to minimize the smoke generated from burning wood by employing a secondary air flow source to provide a second burn of the smoke from the burning wood similar to that disclosed in U.S. Pat. Nos. 11,199,324 and 11,293,642. This type of fire pit is typically referenced as a smokeless fire pit that has shown to be useful.

One issue with the existing smokeless fire pits currently in the market relates to the ability to employ them on an existing wood or Trex like deck without damaging the deck surface due to the high temperatures generated in such smokeless fire pits. Other issues relate to the ability to readily clean out any wood or ash from the smokeless fire pit generated from a previous fire as well as the ability to move the fire pit into a more compact position for storage or transportation.

DETAILED DESCRIPTION OF THE INVENTION

Referring to FIGS. 1, 5 and 6, a portable fire pit 10 sized and configured to burn wood in a clean and mostly smokeless manner is provided. As such, the portable fire pit 10 may include structure that facilitates a secondary burn of the smoke created by the wood so that the portable fire pit 10 appears to burn wood in smokeless manner. Further, the portable fire pit 10 may include structure that minimizes a temperature along an underside of the portable fire pit 10 so that the portable fire pit 10 can burn wood therein and so that the portable fire pit 10 does not become too hot for the surfaces it may be positioned upon. Furthermore, the portable fire pit 10 may include structure that may be readily disassembled to allow the portable fire pit to be cleaned-out as desired. Also, the portable fire pit 10 may be at least partially disassembled to facilitate the portable fire pit to be moved to a compact position or storage position (see FIG. 9). Even further, the fire pit 10 may include various coupling portions that may facilitate coupling secondary components or accessory devices to the fire pit 10.

The portable fire pit 10 may include a main body 12, a stand 28, and a base body 30. The main body 12 may extend with an outer wall 14 and an inner wall 16. The outer wall 14 may extend between a first end 18 and a second end 20. The inner wall 16 may extend to define a chamber 22 therein or wood burning portion. The outer wall 14 and inner wall 16 may extend parallel to each other to define a gap 24 therebetween. The gap 24 may be exposed to external air along a lower portion of the main body and adjacent the second end 20 or lower end of the of the outer wall 14. Further, the inner wall 16, along an upper portion thereof, may include multiple openings 46 defined therein such that the multiple openings 46 may provide air flow between the gap 27 and an upper portion of the chamber 22. The gap 24 may be sized and configured to draw and direct oxygen from adjacent the lower end or second end 20 of the outer wall 14, through the gap 24, and into the upper portion of the chamber 22. The chamber 22 may include a grate 26 positioned therein, the grate being the structure that wood may be positioned on for burning within the chamber 22. The outer wall 14 of the main body 12 may include extension portions 21 that may extend downward from the second end 20 of the outer wall 14. The extension portions 21 may be employed for coupling in the main body 12 to the base body 30. The base body 30 may extend to define inlets 32 therein, the inlets 32 sized and configured to facilitate air flow toward and below the grate 26 to assist in supplying oxygen to the chamber 22. In this manner, oxygen may fuel a fire burning in the chamber 22 of the portable fire pit 10 with oxygen being drawn through the inlets 32 of the base body 30 to fuel a lower portion of the chamber 22 and oxygen being drawn into the gap 24 to be drawn upward through the gap 24 and through the openings 46 of the main body to provide oxygen at an upper portion of the chamber 22 to thereby, facilitate a second burn in the chamber 22.

Now with reference to FIGS. 2 and 3, the fire pit 10 may extend with an octagonal profile or shape or a profile with eight sides. In another embodiment, the fire pit 10 may exhibit a hexagonal profile. In still another embodiment, the fire pit 10 may be cylindrical so as to extend with a circular profile. As set forth, the fire pit 10 may extend with eight sides 34. The various components of the fire pit 10 may extend to correspond with the eight sides 34, such as components of the main body 12, a ring 36, the base body 30, and the stand 28. The fire pit 10 may extend to define an upper side 38 and a lower side 40, which also may be referenced as an upper portion and a lower portion, respectively. The upper side 38 may include the ring 36 and the first end 18 of the outer wall 14 of the main body 12, as well as the openings 46 defined in the upper portion of the inner wall 16 of the main body 12. The ring 36 may be referenced as a cap structure that may removably nest over an upper end or upper portion defined between the outer and inner walls 14, 16 of the main body. Such cap structure 36 may nest within a recess between the outer and inner walls 14, 16 or along an inside surface of the outer wall 16. For example, the first end 18 of the outer wall 14 of the main body 12 may extend to define a first periphery 42. The first periphery 42 may include the ring 36 or cap structure positioned adjacent thereto. The ring 36 may be inset or positioned below the first periphery 42 of the main body 12 so as to be readily removed from the upper side 38 of the fire pit 10 by simply lifting the ring 36 therefrom. In this manner, the ring 36 may be stabilized and removably coupled or removably positioned from adjacent the first periphery 42. The ring 36 or cap structure may extend with an inner periphery 37 that may define a chamber opening 44 for the chamber 22 of the fire pit 10. The chamber opening 44 may also be a ring opening 68. Upon the ring 36 being removed, the first end 18 of the outer wall 14 may extend to define the chamber opening. As set forth, the inner wall 16 of the main body may include the multiple openings 46 defined along an upper portion of the inner wall 16 of the main body 12. Such multiple openings 46 facilitate air flow from the gap 24 defined between the outer and inner walls 14, 16 of the main body 12 to facilitate a second burn within the upper portion of the chamber 22.

With reference to FIGS. 2, 4, 5, 6 and 6A, the fire pit 10 may define an axis 45 extending axially, centrally and symmetrically through the fire pit 10 such that, upon the fire pit 10 being positioned upon a flat horizontal surface, the axis may be oriented vertically through the fire pit 10. The components of the fire pit 10 may symmetrically correspond with each other such that the axis 45 of the fire pit may also extend axially, centrally, and symmetrically through each of the ring 36, main body 12, base body 30 and the stand 28. The lower side 40 of the fire pit 10 may include the second end 20 of the outer wall 14 of the main body 12, the base body 30, and the stand 28, as well as a lower end 47 of the inner wall 16. The lower end 47 of the inner wall 16 of the main body 12 may extend to define a second periphery 48 that may extend lower or beyond the level of the second end 20 of the outer wall 14 (but for the extension portions 21 of the outer wall 14). The lower end 47 of the inner wall 16 may be sized and configured to be positioned along an inside corner 49 of the base body 30. Such positioning may be employed by axially aligning the main body 12 relative to the base body 30 and moving the main body 12 toward the base body 30. Such main body 12 and/or based body 30 may need to be rotated about the axis 45 until the octagonal sides of the main body 12 and based body 30 become aligned. As such, the main body 12 may be rotated about the axis 45 until the lower end 47 and periphery 48 of inner wall 16 of the main body 12 corresponds with the base body 30 to facilitate axial movement of the lower end 47 to be positioned adjacent the inside corner 49. Further, upon positioning the inner wall 16 against the inside corner 49 of the base body 30, the extension portions 21 of the outer wall 14 of the main body 12 may be removably coupled to the base body 30. In one embodiment, the outer wall 14 of the main body 12 may be coupled to outer sides 50 of the base body 30 with base coupling portions 52. Such base coupling portions 52 may include a threaded shaft that may be inserted through openings defined in the main body 12 and base body 30 to removably couple the main body 12 to the base body 30. Such base coupling portions 52 may be in the form of one or more screws or any other coupling structure, such as a latch or the like, or any other suitable coupling mechanism. In another embodiment, the base body 30 may be coupled to at least two extension portion 21 of the outer wall 14 of the main body 12.

The base body 30 may be positioned over the stand 28 so as to sit upon the stand 28. The stand 28 may be configured to be positioned on the ground and extend upwards to hold the base body 30 and suspend the base body 30 above the ground with the main body 12 and the ring 36 positioned on the based body, as set forth. The stand 28 may extend with a lower floor 56. The lower floor 56 may extend with a bevel extending inward towards a lower opening 58 defined on the lower floor 56 of the stand 28. In this configuration, the lower opening 58 may be raised above the ground or surface the stand 28 may be positioned upon. Further, the lower floor 56 may extend to define an outer edge 60. The outer edge 60 may extend prior to the bevel of the lower floor 56 and be configured to stabilize the stand 28 on the ground.

Now with reference to FIGS. 2, 5, 6 and 6A, as previously set forth, the ring 36 may be positioned adjacent the first periphery 42 of the main body 12. The ring 36 may include a ledge 62 and an inclined wall 64. The inclined wall 64 may extend upwards and inwards to the inner periphery 37 to define the chamber opening 44. Further, the inclined wall 64 may extend similar to a bevel towards the chamber opening 44 or ring opening 68. The first periphery 42 or first end 18 of the outer wall 14 may extend upward above the upper end of the inner wall 16 such that a space between the upper end of the inner wall 16 and the outer wall 14 may define a seat 69 (see FIG. 6). The seat 69 may be sized to define a width 70 or a distance between the outer and inner walls 14, 16. The width 70 of the seat 69 may be a similar size as the gap 24. The width 70 of the seat 69 may be sized and configured to receive the ledge 62 of the ring 36 to be positioned thereon. As set forth, the outer wall 14 may extend upward above the inner wall 16 to define a barricade 72. The additional height of the barricade 72 may assist in maintaining the ledge 62 of the ring 36 on the seat 69 of the main body 12.

As previously set forth, the outer and inner walls 14, 16 may extend parallel relative to each other to define the gap 24 therebetween. The inner wall 16 may be configured to extend further downward relative to the outer wall 14 so that the gap 24 may be exposed to external air flow (or an external side of the fire pit 10) to define a gap opening 74. The gap opening 74 may be defined by the second end 20 of the outer wall 14 and the outer surface of the inner wall 16. Further, as previously set forth, the inner wall 16 may define the chamber 22 and may include the grate 26 therein. Further, the inner wall 16 may extend below the grate 26 so that the inner wall 16 extends to the lower end 47, the lower end 47 configured to be positioned in or adjacent the inside corner 49 of the of the base body.

The base body 30 may extend to include a lower level 76, an upper level 78, and a periphery wall 80. The lower level 76 and upper level 78 may extend parallel to one another with a space 82 extending therebetween. The periphery wall 80 may extend from the lower level 76 and extend upward and above the upper level 78. Further, upon the base body being positioned upright in a use position, the periphery wall 80 may include a vertically extending straight portion 84 and a slanted portion 86. The slanted portion 86 may extend from the lower level 76 to the straight portion 84. The straight portion 84 may extend vertically upward from the slanted portion 86 to above the upper level 78 of the base body 30.

As previously stated, the base body 30 may include inlets 32 defined therein. The inlets 32 may be defined on or adjacent to the slanted portion 86 of the periphery wall 80. Further, the inlets 32 may not be defined on each of the outer sides 50 of the base body 30. Rather, the inlets 32 may be defined on every other of the outer sides 50 of the base body 30. Even further, the inlets 32 may extend from an exterior 88 of the fire pit 10 to the space 82 defined between the lower and upper levels 76, 78 of the base body 30. The straight portion 84 may be coupled to and extend upward above the upper level 78 so that the upper level 78 may be positioned into the base body 30. The upper level 78 may extend flat with a base opening 90 therein, the base opening 90 may be centered in the base body 30. The base opening 90 may be circular or other suitable shape, or may exhibit multiple apertures. Further, the base opening 90 may facilitate air flow to the space 82 defined between the lower level 76 and the upper level 78, and continue upward to the space below the grate 26. The upper level 78 may also include multiple brackets 92 and a raised plate 94. The raised plate 94 may be raised and positioned above the base opening 90. In this configuration, the base opening 90 and raised plate 94 may define a base gap 96 therebetween. The multiple brackets 92 may extend upwards past the raised plate 94. Further, the multiple brackets 92 may be sized and configured to hold a tray 98 positioned thereon. The base body 30 may include multiple components that may act as a heat shield or heat barrier to shield the surface that the fire pit sits upon. Such components may include the raised plate 94, as well as the lower and upper levels 76, 78, of the base body 30, as well as other components discussed further herein.

The stand 28 may extend to define the lower floor 56 and an upper floor 100 with a barrier 102 extending therebetween. The lower floor 56, upper floor 100, and barrier 102 may extend as one piece with various portions fixedly coupled together. The lower and upper floors 56, 100 may extend somewhat parallel to one another. Further, the lower floor 56 may include a lower downward extension 57 that may extend from sides or a periphery of the lower floor 56. The upper floor 100 may include an upper downward extension 101 that may extend from sides of the upper floor 100. Such upper downward extension 101 may correspond with the underside of the base body 30 so that the based body 30 may be readily placed and nest with the stand 28. The lower floor 56 may extend to define a lower opening 58 therein. Similarly, the upper floor 100 may extend to define an upper opening 104 therein. Both the lower opening 58 and upper opening 104 may be similar in size and shape, for example, the lower and upper openings 58, 104 may be circular in shape. Further, the lower and upper openings 58, 104 may be positioned above one another and centered within the stand 28 of the fire pit 10. The barrier 102 may extend generally perpendicular to the lower and upper floors 56, 100 and may be coupled thereto. The stand 28 may include stand inlets 106 defined in the barrier 102 of the stand 28. The stand inlets 106 may extend from the lower floor 56 to the upper floor 100 of the stand 28. Further, the stand inlets 106 may be sized and configured for facilitate the free flow of air below the fire pit 10 and through the stand 28. Similar to the inlets 32 defined on the base body 30, the stand inlets 106 may be positioned on multiple sides 34 of the fire pit 10. However, the stand inlets 106 may be positioned at least every other of the sides 34 such that the barrier 102 may extend between each of the stand inlets 106. As previously stated, the lower floor 56 may include the outer edge 60. The outer edge 60 may extend perpendicular and away from the barrier 102. Such outer edge 60 may be sized and configured to sit directly on the surface that the fire pit is positioned above, such as a ground surface, a floor surface, a deck surface, a table surface or any other suitable surface.

With reference to FIGS. 6, 6A and 7A, as previously set forth, the seat 69 may extend perpendicular to the outer and inner walls 14, 16 of the main body 12. The ring 36 may include the ledge 62 sized and configured to be positioned on the seat 69 of the main body 12 such that the ring 36 may be removable from the seat 69. Upon the ring 36 being positioned on the seat 69, the inclined wall 64 may extend partially over and above the chamber 22 such that the inner periphery 37 of the ring 36 may define the chamber opening 44. The chamber opening 44 may be configured to facilitate access into the chamber 22. The chamber 22 may include the grate 26 positioned therein, the grate extending to define an upper chamber 108 and a lower chamber 110. The grate 26 may be sized and configured for wood to be positioned thereon, such that, the wood may be lit to create a fire within the upper chamber 108. The grate 26 may be coupled to the inner wall 16 by an angled edge 112. The angled edge 112 may extend upwards from the inner wall 16 to a grated surface 114 of the grate 26. The grated surface 114 may extend perpendicular to the inner wall 16. Further, the grated surface 114 may extend with grate openings 116 defined thereon. The grate openings 116 may facilitate air flow from the lower chamber 110 to the upper chamber 108.

As previously set forth, the extension portions 21, as extensions from the outer wall 14 of the main body 12 may be coupled to the outer side 50 of the base body 30. More specifically, the extension portions 21 of the outer wall 14 may be coupled to the periphery wall 80 of the base body 30 by base coupling portions 52, such as screw like structures. When the outer wall 14 of main body 12 may be coupled to the base body 30, the inner wall 16 may extend into the base body 30 parallel to the periphery wall 80 of the base body 30. Further, the inner wall 16 may extend to rest on the upper level 78 of the base body 30 at the inside corner 49 of the base body 30. As such, the raised plate 94, multiple brackets 92, and the tray 98 may be positioned within the lower chamber 110 of the chamber 22. In another embodiment, the base body and the tray 98 may be positioned within the lower chamber 110 below the grate 26.

Now with reference to FIGS. 7, 7A, 8 and 8A, as previously set forth, the grate 26 may be sized and configured for wood to be positioned thereon within the chamber 22. The tray 98 may be positioned directly below the grate 26 and may extend parallel to the grated surface 114. Further, the tray 98 may be sized to generally expand the same area as the grated surface 114. As such, upon igniting wood within the chamber, the tray 98 may be configured to capture ash and other debris from the wood positioned above on the grate 26. With the main body 12 coupled to the base body 30, the base body 30 may be positioned on the upper floor 100 of the stand 28. As previously set forth, the upper floor 100 of the stand 28 may also extend with a bevel or upper downward extension 101 such that the upper downward extension 101 may be sized and configured to correspond with the bevel or underside 66 (see FIGS. 5 and 6) of the lower level 76 of the base body 30 so that the base body 30 nests or fits with the structure of the stand 28. In this manner, each of the ring 36, main body 12, base body 30, and stand 28 may be removably coupled to one another.

As previously stated, the base body 30 may include the inlets 32 defined on the slanted portion 86 of the periphery wall 80. The inlets 32 may be sized and configured for air from the exterior 88 of the fire pit 10 to flow into the base body and into the lower chamber 110. The air may flow into the space 82 defined between the lower level 76 and upper level 78 of the base body 30, as shown by arrow 118. Once the air has entered the space 82, the air may be directed through the base opening 90 where the raised plate 94 may push and direct the air towards the periphery wall 80 of the base body 30 as shown by arrow 120. The air may then be directed up to the angled edge 112 and the grated surface 114, as shown by arrow 122. With this arrangement, the structure of the base body facilitates a constant flow of oxygen to the lower chamber 110 and chamber 22 to feed a fire burning in the fire pit 10.

As previously set forth, the gap 24 defined between the outer wall 14 and inner wall 16 of the main body 12 may provide air flow therein toward an upper portion of the chamber 22. The gap opening 74 may provide access for air to be directed therein and flow upwards towards the first end 18 of the main body 12 as shown by arrow 124. The air may then flow through the multiple openings 46 defined on the inner wall 16 into the chamber 22, as shown by arrow 126. In this manner, the fire may be fed a constant flow of oxygen along the upper side 38 of the fire pit 10. Further, the oxygen provided at an upper portion of the chamber 22 may provide a second burn of the smoke of the fire such that the smoke may be burned off prior to escaping the chamber 22.

The gap 24 may also provide an air buffer between the chamber 22 and the exterior 88 of the fire pit 10. As such, the gap 24 may also keep the exterior 88 of the fire pit 10 or the outer wall 14 of the main body 12 from overheating. The stand inlets 106 may be configured to provide air flow throughout the stand 28 such that heating of the stand 28 and base body 30 may be minimized. The air may enter the stand 28 through the stand inlets 106, as shown by arrow 128. The air may then flow to the upper opening 104 on the upper floor 100 of the stand 28. The lower level 76 of the base body 30 may be positioned directly on the upper floor 100 such that the air may cool the lower level 76 of the base body 30 from the upper opening 104. Further, various components may act as heat shield to assist in minimizing heat reaching the ground surface or the surface the fire pit sits upon, such as the tray 98, raised plate 94, upper level 78, lower level 76. Further, the lower floor 56 and the upper floor 100 of the stand 28 may also act as a heat shield in assisting to minimize heating the ground surface or floor surface or the like.

Now with reference to FIGS. 9-11, the fire pit 10 may be configured to be moved from the use position to a compact position or storage position. As previously set forth, the main body 12 may be coupled to the base body 30 by the base coupling portions 52 and the base body 30 may be positioned on the upper floor 100 of the stand 28. Upon it being desired to store or transport the fire pit 10, the components of the fire pit 10 may readily be disassembled from the use position and placed in the compact or storage position. The stand 28 may be sized and configured so that a portion of the stand may fit within the chamber 22 of the main body 12. That is, the stand may be turned upside-down so that the upper floor 100 may first be inserted within the chamber 22 so that the outer edge 60 of the stand lays upon the seat 69 of the main body 12. As such, disassembly of the fire pit 10 may be employed by lifting the main body 12 and base body 30 from the stand 28, and removing the ring 36 from the main body 12. The stand 28 may then be rotated upside-down and positioned within the chamber 22 so that the outer edge 60 sits engaged to rest on the seat 69 of the main body 12. The ring 36 may then be replaced over the top side of the main body 12. The outer wall 12 extends a height above the seat 69 such that the stand 28 and ring 36 may be maintained in the compact position as long as the fire pit remains upright. In this manner, the fire pit 10 may be readily moved from a use position to a compact position for storing the fire pit, for example. Further, such compact position may also be useful when transporting the fire pit as well as for packaging purposes.

The stand inlets 106 of the stand 28 may be configured to allow for air flow through the stand 28, which may minimize heating of the stand 28, as well as the lower level 76 of the base body 30. Similarly, the inlets 32 of the base body 30 may assist to minimize heating the underside of the base body. As such, the stand inlets 106, as well as the inlets 32 of the base body 30, may allow for the stand 28 and the base body 30 to quickly cool such that the fire pit 10 may be put into the compact position soon after the use of the fire pit 10.

In another embodiment, the fire pit 10 may readily be disassembled to clean-out the fire pit 10. For example, the base coupling portions 52 may be removed from the extension portions 21 of the main body 12. Upon the base coupling portions 52 being removed, the base body 30 may be slidingly removed from the underside of the main body 12, which will expose the tray 98. The tray 98 may simply be lifted-up from the brackets 92. The ash in the tray may be dumbed and cleaned-off. The based body may also cleaned-out and, if there is any debris on the top side of the grate in the chamber 22 of the fire pit 10, the main body may simply be turned upside-down to remove such debris. The user may then quickly replace the tray 98 to sit on the brackets of the base body 30, then the base body may be re-inserted back into the underside of the main body 12 (into the lower chamber 110 until appropriately positioned so that the base coupling portions 52 can be replaced to couple the main body 12 to the base body 30.

With reference to FIGS. 1 and 2, the main body 12 of the fire pit 10 may include upper coupling portions 15. The upper coupling portions 15 may be positioned along an external surface of the outer wall 14 of the main body 12 with two upper coupling portions 15 on opposing sides of the main body 12. Further, the upper coupling portions 15 may include structure similar to the base coupling portions 52. Each of the upper coupling portions 15 may include a knob 17 and a threaded shaft (not shown) that may be wound into and out of openings (not shown) defined in the outer wall 14 of the main body 12. The upper coupling portions 15 may be partially withdrawn from a given opening so that various other components, such as accessory device may be saddled over the shaft and be sandwiched against the outer wall 14 by tightening the knob 17 against the component or accessory device. The various components or accessory devices that may be employed to be coupled to the main body 12 with the upper coupling portions 15 may include, handles, a heat deflector, a spark deflector, a griddle and/or a grill, or any other suitable component or accessory device sized and configured to be coupled to the fire pit 10.

Now with reference to FIGS. 12-15, another embodiment of a fire pit 150 is provided. The fire pit 150 of this embodiment may include similar components including a ring 152, a main body 154, a base body 156, and a stand 158. The structure of the fire pit 150 may function in a similar manner as that set forth in the previous embodiment. The ring 152 may include a ledge 160 and an inclined wall 162. The main body 154 may define an outer wall 164 and an inner wall 166. The inner wall 166 may extend to define a chamber 168 within the main body 154. The outer wall 164 may extend above the inner wall 166 to a first end 170. The inner wall 166 may extend below the outer wall 164 to second end 172 of the main body 154. The first end 170 may extend to define a first periphery 174. The inner and outer walls 164, 166 may extend parallel relative to each other so that the distance between inner and outer walls 164, 166 defines a width 176. The inner wall 166 may terminate at a top side thereof to define a seat 159, the seat 159 extending to the outer wall 164. Such ledge 160 of the ring 152 may be configured to rest on the seat 159 of the main body 154.

The base body 156 may extend to define a lower level 178, an upper level 180, and a periphery wall 182. The periphery wall 182 may extend from the lower level 178 to the upper level 180. The upper level 180 may include a grate 184 thereon. The grate 184 may extend to define an angled edge 186 and a grated surface 188. The grated surface 188 may include grate openings 190 defined therein. The grated surface 188 and the lower level 178 may extend parallel while the periphery wall 182 may extend perpendicular to the lower level 178 and grated surface 188. The periphery wall 182 may include inlets 192 defined thereon. The inlets 192 may be positioned on corners 194 of the base body 156. Further, the inlets 192 may not extend the full length of the periphery wall 182. The lower level 178 may define a topside 196 and a bottom side 198. Further, the lower level 178 may extend to a base opening 200 defined therein. The base opening 200 may extend from the topside 196 to the bottom side 198 of the lower level 178. The base body may also include a lower plate 202 that may be positioned directly below the base opening 200 and extending from the bottom side 198 of the lower level 178. Such lower plate 202 may act as a heat shield. The bottom side 198 may also include multiple brackets 204 extending downwards therefrom.

The stand 158 may extend to define stand legs 206, a floor 208, and a barrier 210. The stand legs 206 may be coupled to both the floor 208 and the barrier 210. Further the stand legs 206 may extend from the floor 208 towards a ground that the fire pit 150 may be positioned upon. The barrier 210 may extend upwards above the floor 208. In this manner, the barrier 210 may be above the floor 208 so that the floor 208 may be inset relative to a height of the barrier 210. Upon the base body 156 being positioned over the stand, the lower level 178 of the base body and the floor 208 of the stand may define a hollow portion 212 therebetween. Further, the floor 208 may define a top 214 and a bottom 216. The bottom 216 may include supports 218 extending therefrom to a bottom plate 220.

Similar to the previous embodiment, the ring 152, the main body 154, the base body 156, and the stand 158 may be coupled to one another. The ring 152 may be positioned on the seat 159 of the main body 154 such that the ring 152 may rest on the seat 159. The main body 154 may extend from the first end 170 of the outer wall 164 to the second end 172 of the inner wall 166. Adjacent to the second end 172 of the inner wall 166, the inner wall 166 may define lower vents 240 therein. Such lower vents 240 may provide oxygen to the underside of the grate 184. In this embodiment, the base body 156 may be slidingly positioned in a lower portion of the chamber 168 so that extension portions 221 of the outer wall 164 may be coupled to the stand 158. That is, the extension portions 221 of the outer wall 164 of the main body 154 may be coupled to the barrier 210 of the stand 158 by screws 222. As such, the main body 154 may be removably coupled to the stand 158. Further, the outer wall 164 may be coupled to the stand 158 on one or more faces 224 of the main body 154.

With the stand 158 coupled to the main body 154, the inner wall 166 of the main body 154 may extend over the base body 156 such that the base body 156 may be positioned into the chamber 168 from the underside thereof. The inner wall 166 may extend over the periphery wall 182 of the base body 156. The base body 156 may be positioned on the stand 158 where the multiple brackets 204 extending from the bottom side 198 of the base body 156 may be set on the top 214 of the floor 208 of the stand 158. As such, the multiple brackets 204 may be sized and configured to hold the base body 156 up from the stand 158. In this manner, the fire pit 150 may be assembled.

With the base body 156 positioned within the chamber 168 of the main body 154, the grate 184 may extend adjacent the inner wall 166 of the main body 154. More specifically, the angled edge 186 of the grate 184 may be positioned adjacent the inner wall 166. Further, the angled edge 186 may extend upwards towards the grated surface 188 of the grate 184. The grate 184 may be sized and configured for wood to be positioned and ignited thereon. The base body 156 may include a tray 226 positioned therein. The tray 226 may be positioned directly below the grate 184 and be coupled to the angled edge 186 of the grate 184. Further, the tray 226 may be coupled to the grate 184 where the inlets 192 are defined on the periphery wall 182 of the base body 156. The tray 226 may be sized and configured to capture ash and other debris from the wood positioned on the grate 184. The tray may also act as a heat shield to minimize heating the floor the fire pit 150 is positioned upon. In one embodiment, the grate 184 may be removably coupled to the base body 156 such that the tray 226 may be emptied and cleaned out.

Similar to the previous embodiment, the outer wall 164 and the inner wall 166 of the main body 154 may define a gap 228 therebetween, the gap 228 having a gap opening 230 adjacent an end of the outer wall 164. Further, the gap opening 228 may be defined where exterior air may flow into the gap 228, as depicted by arrow 234. The air may flow upward through the gap 228 towards the first end 170 of the main body 154 and through multiple openings 236 defined on the inner wall 166 at an upper portion of the chamber 168, as depicted by arrow 238. In this manner, oxygen may be provided at an upper portion of the chamber to provide a second burn of the fuel in the fire pit to, thereby, burn the smoke produced by the wood prior the smoke leaving the chamber 168.

As previously set forth, the lower vents 240 defined in the inner wall 166 of the main body 154 may facilitate providing oxygen to an underside of the chamber 168. Air may flow into the fire pit 150 through the lower vents 240 defined on the inner wall 166 and under the lower level 178 of the base body 156, as shown by arrow 242. Once the air is flowing between the lower level 178 of the base body 156 and the floor 208 of the stand 158, the air may then be directed by the lowered plate 202 through the base opening 200, as shown by arrow 244. The tray 226, being positioned above the base opening 200, may direct air flow towards the periphery wall 182 before being directed to the grated surface 188 of the grate 184 as shown by arrow 246. In this manner, oxygen may flow to the burning wood and may provide oxygen to the fire within a lower side of the chamber 168 in the main body 154.
