For example, an axle may extend between the first fixed caster wheel 16a and the second fixed caster wheel 16b, but not between the first swivel caster wheel 14a and the second swivel caster wheel 14b.

(29) FIG. 6 shows the cover 28 uncoupled from the fire pit 22. The cover 28 may detachably couple to the fire pit 22 via a friction fit. In many embodiments, the cover 28 restably couples to the fire pit 22. As indicated in FIG. 5, FIGS. 7-9 focus on the cover 28. Turning now to FIG. 7, a bottom perspective view of the cover 28 is shown. In some embodiments, the cover 28 includes at least one foldable leg 36 coupled to a bottom portion 38 of the cover 28 such that when the cover 28 is adjoined to the fire pit 22, the at least one foldable leg 36 is located inside the fire pit 22. As demonstrated in FIG. 7, the cover 28 may define a depth greater than the at least one foldable leg 36 in the folded position, such that the at least one foldable leg 36 may not extend past the cover 28. The depth may define about 2 inches. In addition, in many embodiments, the cover 28 is configured to fit over an outer edge of the fire pit 22, as opposed to within an interior portion of the fire pit 22. Accordingly, as illustrated, the at least one foldable leg 36 may not extend all the way to an inner edge of the cover 28 in order to leave room for a top edge of the fire pit 22 to be received by the cover 28. In some embodiments, the at least one foldable leg 36 is configured to unfold and restably couple to a ground surface such that the cover 28 and the at least one foldable leg 36 form a table 40, as shown in FIGS. 8 and 9.

(30) FIG. 8 illustrates a bottom perspective view and FIG. 9 illustrates a side view of the table 40 formed by the cover 28 and at least one foldable leg 36. As shown in FIG. 8, in many embodiments, the at least one foldable leg 36 comprises four straight legs configured to extend from the bottom portion 38 of the cover 28 at a 90 degree angle. The at least one foldable leg 36 may comprise 1.0 inch1.0 inch0.065 inch bars with a length of 21 inches. The at least one foldable leg 36 may comprise solid or hollow legs. The at least one foldable leg 36 may comprise more than four legs and may comprise straight or bowed legs. The at least one foldable leg 36 may comprise fewer than four legs and may comprise straight or bowed legs. In some embodiments, the at least one foldable leg 36 forms an X shape beneath the cover 28, rather than having the perpendicular bars and 90 degree angles shown in FIG. 8.

(31) In some embodiments, the at least one foldable leg 36 comprises a first leg assembly and a second leg assembly. The first leg assembly may include a first leg, a second leg, a threaded bar coupling the first leg to the second leg, a 0.75 inch0.5 inch bar coupled to the threaded bar, and a notched bar coupled to 0.75 inch0.5 inch bar via a hinge. The second leg assembly may include a third leg and a fourth leg, as well as a 0.5 inch0.5 inch bar coupling the third leg to the fourth leg. In many embodiments, when the at least one foldable leg 36 is in an unfolded position, the notched bar is configured to extend and the notch is configured to receive the 0.5 inch0.5 inch bar, thereby coupling the first leg assembly to the second leg assembly. The threaded bar may also comprise a 0.5 inch0.5 inch bar, and may be configured to couple to the first leg and the second leg via a bolt, screw, or similar threaded coupling mechanism. In some embodiments, the 0.75 inch0.5 inch bar defines a length of 10 inches, and is coupled to the threaded bar via welding or a similar method. The notched bar may also comprise a 0.75 inch0.5 inch bar, with a length of 7.625 inches and a notch width of 0.56 inches. All of the listed dimensions are included as examples and intended to be non-limiting. Each of the first leg, second leg, third leg, fourth leg, threaded bar, notched bar, the 0.5 inch0.5 inch bar extending between the third and fourth legs, and the 0.75 inch0.5 inch bar coupled to the threaded bar may comprise solid bars or hollow tubes.

(32) The table 40 may comprise spring clips coupled to the bottom portion 38 of the cover 28, and the spring clips may be configured to hold the at least one foldable leg 36 in the folded position. The table 40 may comprise any number of suitable mechanisms for retaining the at least one foldable leg 36 in the folded position. The table 40 may comprise fewer than four spring clips, as shown in FIG. 7, because, in some embodiments, only two legs are required to be retained in spring clips to keep all four legs in the folded position. In addition to the spring clips (or similar mechanism), the table 40 may comprise metal clips configured to couple each leg of the at least one foldable leg 36 to the bottom portion 38 of the cover 28. The metal clips may comprise an inverted U shape, where a flat base of the inverted U is configured to couple to the bottom portion 38 and the sides of the U are configured to receive each leg. In some embodiments, each leg comprises a first end rotatably coupled to a metal clip via at least one bolt, screw, or similar mechanism (to allow the legs to fold and unfold) and a second end configured to contact a ground surface. The metal clips may comprise any suitable material(s), including plastic. The metal clips may be fixedly coupled to the cover 28 via welding, adhesive, or a similar method. The spring clips may be mechanically coupled to the cover 28 via a rivet, screw, bolt, or similar mechanism.

(33) As previously mentioned, in many embodiments, the cover 28 comprises a flat cover as shown in FIG. 9. Having a flat cover 28 may enable users to most effectively use the table 40 by providing maximum tabletop space. For example, if the at least one handle 35 were located on top of the cover 28, rather than on the sides (as shown in FIG. 8), there would be less space on top of the table 40 to place food, drinks, grilling utensils, and/or other items. In addition, if the cover 28 had a domed shape like a cover for a traditional barbecue grill, rather than the flat shape shown in the Figures, the cover 28 would not be able to be used as a table 40. A top surface of the cover 28 may be configured to extend slightly beyond (e.g., overhang) the rest of the cover 28, as shown in FIGS. 7 and 8. In some embodiments, the top surface of the cover 28 defines a diameter of about 31.25 inches and a depth of about 0.125 inches. The rest of the cover 28 may define a diameter of about 30.75 inches, a depth of about 2 inches, and a wall thickness of about 0.125 inches. Accounting for the length of each leg of the at least one foldable leg 36, the top surface of the cover 28, and the metal clips coupling each leg to the cover 28, the overall height of the table 40 may be about 22 inches. These dimensions are included as non-limiting examples.

(34) FIG. 10 shows another top perspective view of the portable fire pit 10, including the suspension grate 52 and handle 48. In some embodiments, the suspension grate 52 is detachably coupled to the fire pit 22 and is configured to hold firewood 54, as shown in FIGS. 1 and 2. The suspension grate 52 may also comprise a plurality of handles coupled to a top surface 60 (shown in FIG. 11) of the suspension grate 52, where the plurality of handles may be configured to enable a user to move the suspension grate 52. In many embodiments, the plurality of handles comprises two handles. Each handle may comprise 0.25 inch round bar with an inner width of 3.75 inches, an outer width of 4.25 inches, and a length of 2.625 inches. These dimensions are included as examples and intended to be non-limiting.

(35) In some embodiments, the suspension grate 52 defines a diameter of about 28 inches. The suspension grate 52 may include + shaped support bars to prevent sagging of the grate 52 under the weight of firewood 54. In some embodiments, the support bars comprise 0.5 inch0.5 inch0.065 inch tubes. The suspension grate 52 may also comprise a rolled angle outer edge configured to couple to the plurality of handles. The rolled angle outer edge may define a 0.75 inch0.125 inch angle with a 28 inch diameter. In many embodiments, the rolled angle outer edge is configured to couple to #9 expanded steel, which forms the grate part of the suspension grate 52. The grate may define a diameter of about 27.275 inches and a thickness of 0.134 inches. As indicated in FIG. 10, FIG. 11 illustrates a cross-sectional view of the fire pit 22. For the sake of clarity of the Figures, FIG. 11 may not include all of the same elements as FIG. 10. For example, FIG. 11 does not include the wheels, which are shown in FIG. 10.

(36) In many embodiments, the suspension grate 52 comprises a plurality of legs 56 coupled to a bottom surface 59 of the suspension grate 52 and located opposite the plurality of handles, indicated by the suspension grate handle 57 in FIG. 11. The plurality of legs 56 may comprise 0.5 inch0.5 inch0.065 inch tubes, like the support bars discussed above. The plurality of legs 56 may be configured to couple to the support bars. In some embodiments, the plurality of legs 56 comprises five legs. The plurality of legs 56 may comprise fewer than five legs. The plurality of legs 56 may comprise more than five legs. FIG. 11 also shows that the plurality of legs 56 may be configured to restably couple to an internal bottom portion 58 of the fire pit 22, such that the top surface 60 of the suspension grate 52 is located a first distance 62 above the internal bottom portion 58 of the fire pit 22. In some embodiments, the first distance 62 is about 5 inches. The first distance 62 may be greater than 5 inches. In some embodiments, the first distance 62 is less than 5 inches. When the first distance 62 is about 5 inches, the fire pit 22 may have about 7 inches for firewood 54 between the top surface 60 of the suspension grate 52 and the top portion 30 of the fire pit 22. Of course, the firewood 54 may extend above the top portion 30 of the fire pit 22.

(37) The area between the suspension grate 52 and the internal bottom portion 58 of the fire pit 22 may comprise an area for ash collection while burning a fire in the fire pit 22. The area may also help keep a fire burning by allowing air circulation beneath the suspension grate 52, and, therefore, beneath the fire. The possibility of air circulation within the fire pit 22 further distinguishes the claimed portable fire pit 10 from traditional fire pits, which often require at least one ventilation opening on a side wall to enable air circulation. In contrast, the portable fire pit 10 comprises a solid fire pit 22 with the at least one solid vertical wall 26, and no ventilation openings. In addition, the bottom piece of the fire pit 22 may comprise a solid, non-vented surface substantially similar to the at least one solid vertical wall 26 with a thickness of about 0.135 inches. In many embodiments, the bottom piece is welded, or coupled in a similar permanent manner, to the at least one solid vertical wall 26.

(38) As previously mentioned, the cover 28 may be used to quickly extinguish the fire. The ability to quickly extinguish the fire further distinguishes the present invention from a traditional campfire-style fire pit, which may often take a significant amount of time to completely burn out. As the fire in the fire pit 22 is extinguished, smoke may escape from a gap between the fire pit 22 and the cover 28. Stated differently, the cover 28 may not form an air-tight seal to the fire pit 22, but may block the intake of air enough to snuff out a fire. In many embodiments, like the at least one solid vertical wall 26, the cover 28 also comprises a solid surface with no ventilation openings. After allowing the ashes to cool for an appropriate amount of time (e.g., overnight), a user may then remove the suspension grate 52 via the suspension grate handle 57 and/or a plurality of handles, and scoop or dump out the ashes for proper disposal. Due to the large size of the fire pit 22 and the ample space below the suspension grate 52, a user may be able to burn several fires before needing to empty out the ashes.

(39) The fire pit 22 may also comprise a trapdoor-type mechanism located in the internal bottom portion 58 for ash removal. The trapdoor-type mechanism may comprise a locking mechanism in order to prevent the accidental release of hot ashes; for example, when moving the portable fire pit 10. FIG. 11 also illustrates that, in many embodiments, the fire pit 22 comprises a plurality of post receivers 66 coupled to an interior portion 68 of the at least one solid vertical wall 26. The plurality of post receivers 66 may be configured to couple to a grill rack 64, which will be discussed in greater detail later in the disclosure.

(40) Turning now to FIG. 12, a perspective view of the handle 48, including a first end 50a and second end 50b, is shown. In many embodiments, the first end 50a is configured to detachably couple to a hitch 46 (shown in FIG. 13) coupled to the front portion 18 of the housing 12. The second end 50b may be configured to be pulled and/or pushed by a user in order to move the portable fire pit 10. When the handle 48 is detached from the housing 12, as illustrated in FIG. 12, the handle 48 may be configured to operate as a fire poker. The second end 50b of the handle 48 may define a triangle shape, as shown in FIG. 12, or may define any other suitable shape. For example, the second end 50b may define a shape substantially the same as the first end 50a. The second end 50b may also define another shape, such as a rectangular shape. In some embodiments, the handle 48 defines a total length of about 30 inches from the first end 50a to the second end 50b. The handle 48 may define a length of less than 30 inches. The handle 48 may define a length greater than 30 inches. In some embodiments, the second end 50b defines a width of about 5.5 inches to allow a user to comfortably pull and/or push the portable fire pit 10 via the second end 50b of the handle 48. Each of the first end 50a, second end 50b, and middle section of the handle 48 may comprise 0.625 inch0.083 inch round metal tubing. The dimensions included herein are intended as non-limiting examples, and actual dimensions of the handle 48 may vary from the exact dimensions listed here.

(41) FIG. 13 shows a top perspective view of the fire pit 22. Included in FIG. 13 are the housing 12 with the front portion 18 and rear portion 20, as well as the wheel mounts discussed with reference to FIG. 5. FIG. 13 also shows the hitch 46 which, in many embodiments, is configured to detachably couple to the first end 50a of the handle 48. The first end 50a may be configured to fit within the hitch 46 such that either side of the hitch 46 is located on the outer ends of the first end 50a, and the hitch 46 receives the first end 50a. The hitch 46 may define an inner width of about 3.875 inches, and, accordingly, the first end 50a may define a width substantially equal to, or slightly less than, 3.875 inches. For example, the first end 50a may define a width of about 3.75 inches. The hitch 46 may extend from the front portion 18 a distance of about 2.5 inches and may comprise a height of about 1.5 inches, such that the hitch 46 is flush with the top and bottom edges of the front portion 18 of the housing 12. These dimensions are included as examples and intended to be non-limiting. In some embodiments, the hitch 46 is fixedly coupled to the housing 12. The hitch 46 may be secured to the first end 50a via any number of possible mechanisms, including at least one locking pin or similar devices. In some embodiments, the at least one locking pin (or similar device) extends through a first side of the hitch 46, all the way through the first end 50a of the handle 48, and through the second side of the hitch 46.

(42) FIG. 13 also shows the plurality of post receivers 66 located on the interior portion 68 of the fire pit 22. The plurality of post receivers 66 may be arranged such that the top edge of each post receiver is substantially flush with the top edge of the fire pit 22. In this way, the plurality of post receivers 66 may be configured to not impede placement of the cover 28 over the fire pit 22. In some embodiments, the plurality of post receivers 66 comprises a first post receiver defining a first height, a second post receiver defining a second height, and a third post receiver defining a third height. The first height may be about 5 inches, the second height may be about 3 inches, and the third height may be about 2 inches. With the exception of the height, each post receiver may define substantially the same dimensions. For example, in some embodiments, each post receiver defines a 0.75 inch0.083 inch seamless tube with a 0.125 inch end cap located on a bottom portion of each tube (e.g., closest to the suspension grate 52). Each post receiver of the plurality of post receivers 66 may define a different height (or other dimension) than stated in this disclosure. In many embodiments, each post receiver of the plurality of post receivers 66 defines a different height such that the plurality of post receivers 66 defines three different heights.

(43) FIG. 14 shows a grill rack 64 coupled to the plurality of post receivers 66. In some embodiments, the portable fire pit 10 comprises a grill rack 64 including an elongate post 70 (shown in FIG. 15) extending away from the grill rack 64. The grill rack 64 may be located over the fire pit, as illustrated in FIG. 14, and may be configured to hold a food product. Accordingly, the grill rack 64 may be used to heat food over the fire pit 22. In many embodiments, the plurality of post receivers 66 are configured to receive at least a portion of the elongate post 70 and position the grill rack 64 at different heights over the fire pit 22, according to the height of each post receiver. Each post receiver of the plurality of post receivers 66 may comprise a cylinder with a closed end to prevent the elongate post from sliding too far through each post receiver.

(44) A perspective view of the grill rack 64 coupled to the elongate post 70 is shown in FIG. 15. The grill rack 64 may be fixedly coupled to the elongate post 70, such as via at least one of welding, adhesive, mechanical coupling (e.g., bolt, screw, etc.), or a similar method. In some embodiments, the elongate post 70 defines a length of about 9 inches. The elongate post 70 may define a length less than 9 inches. In some embodiments, the elongate post 70 defines a length greater than 9 inches. As illustrated in FIG. 15, the grill rack 64 may define a rectangular shape. In some embodiments, the grill rack 64 defines a square shape and measures about 12 inches12 inches. The grill rack 64 may define any suitable shape, including a circle, an oval, a triangle, and the like. The elongate post 70 may be substantially centered on one edge of the grill rack 64. In some embodiments, the grill rack 64 defines a first size and the fire pit 22 defines a second size that is larger than the first size. The first size may be larger than the second size. In some embodiments, the first size is substantially the same as the second size. In a square/rectangular embodiment, the grill rack 64 may comprise 0.25 inch round bars along all four edges and along a center portion, and may comprise 0.125 inch round bars extending across opposite edges to form the rack portion of the grill rack 64, as shown in FIG. 15. The elongate post 70 may comprise a 0.5 inch round bar.

(45) In many embodiments, the grill rack 64 is configured to rotate between a first position 72a, shown in FIG. 16, and a second position 72b, shown in FIG. 19. In the first position 72a, as demonstrated in FIG. 16, at least a portion of the grill rack 64 may be located directly over the fire pit 22. Comparatively, as demonstrated in FIG. 19, when the grill rack 64 is in the second position 72b, at least a portion of the grill rack 64 may not be located directly over the fire pit 22. FIG. 16 also shows the grill rack 64 at a first height 78a. As previously discussed, the grill rack 64 may be configured to be located at different heights over the fire pit 22 depending on which post receiver of the plurality of post receivers 66 is coupled to the grill rack 64. FIG. 16 shows the grill rack 64 coupled to the first post receiver, or the leftmost/longest post receiver. The first height 78a may represent the lowest height of the grill rack 64. Stated differently, in many embodiments, when the grill rack 64 is coupled to the longest post receiver, the grill rack 64 is lowest over the fire pit 22.

(46) FIGS. 17 and 18 illustrate the grill rack 64 at a second height 78b and third height 78c, respectively. At the second height 78b, as shown in FIG. 17, the grill rack 64 may be coupled to the second post receiver (e.g., the middle post receiver). At the third height 78c, as shown in FIG. 18, the grill rack 64 may be coupled to the third post receiver (e.g., the rightmost/shortest post receiver). It should be noted that the first, second, and third heights 78a, 78b, 78c may be slightly exaggerated in the Figures, in order to clearly demonstrate the different heights. In some embodiments, there is only a few inches of difference between the first, second, and third heights 78a, 78b, 78c. The ability to place the grill rack 64 at different heights above the fire pit 22 may be helpful for a number of reasons. For example, if a large fire is built in the fire pit 22 using firewood 54, as illustrated in FIGS. 1 and 2, the second or third height 78b, 78c may be preferable to avoid burning any food located on the grill rack 64. However, if a smaller fire is built, for example with charcoal or only one or two pieces of firewood 54, the first height 78a may be suitable for cooking with less risk of burning the food.

(47) As discussed with reference to FIG. 16, FIG. 19 shows the grill rack 64 in the second position 72b. The second position 72b may define a position where the grill rack 64 is mostly, though not completely, pivoted away from the fire pit 22. In some embodiments, the second position 72b defines a position where the grill rack 64 is completely rotated such that none of the grill rack 64 is located over the fire pit 22. A completely rotated position may be ideal for some situations, like ensuring safety when placing food on/taking food off the grill rack 64 by rotating the grill rack 64 as far away from the fire as possible. It should be noted that the grill rack 64 may be configured to rotate between the first position 72a and the second position 72b at any of the first, second, and third heights 78a, 78b, 78c.

(48) FIG. 20 shows a bottom perspective view of the portable fire pit 10, with an inset view of the grill rack 64. As illustrated in FIG. 20, in many embodiments, the fire pit 22 comprises a plurality of brackets 74 located on a bottom portion 76 of the fire pit 22, the plurality of brackets 74 configured to slideably receive the grill rack 64 when the grill rack 64 is not in use. As shown, the plurality of brackets 74 may be configured to slideably receive the grill rack 64 in an inverted position such that the elongate post 70 may be located adjacent the at least one solid vertical wall 26 and extend from the bottom portion 76 of the fire pit 22 to the top portion 30 of the fire pit 22.

(49) The plurality of brackets 74 may be considered a type of rail system comprising two L-shaped rods fixedly coupled to the bottom portion 76 of the fire pit 22. Each L-shaped rod may define the following dimensions: 0.75 inches0.75 inches0.125 inches. Each L-shaped rod may be about 27.27 inches long. The L-shaped rods may define dimensions other than those listed in this disclosure, which are intended to convey a non-limiting example. The plurality of brackets 74 may be spaced from one another a distance slightly greater than the width of the grill rack 64, such that the grill rack 64 is securably received. For example, the grill rack 64 may define a width of about 12 inches and the plurality of brackets 74 may be spaced from one another a distance of about 12.375 inches, from outer edge to outer edge. In some embodiments, in order to fit beneath the fire pit 22, the grill rack 64 defines a size that is equal to or less than a distance between the front portion 18 and rear portion 20 of the housing 12. As shown in the Figures, the front portion 18 and rear portion 20 may be physically spaced and separate from one another, with no direct contact between the front and rear portions 18, 20.

(50) Ski Embodiment

(51) Though not illustrated in the Figures, in some embodiments, a portable fire pit comprises skis rather than the first and second pair of wheels 14, 16 of the portable fire pit 10. The portable fire pit may comprise a first pair of skis operatively and removably coupled to a front portion of a housing, a second pair of skis operatively and removably coupled to a rear portion of the housing, and a fire pit coupled to a top portion of the housing. In many embodiments, the portable fire pit described herein is substantially the same as the portable fire pit 10, with the exception of the inclusion of skis rather than wheels. For example, the portable fire pit with skis may also include a handle detachably coupled to the housing, wherein the handle may be configured to allow a user to pull and/or push the portable fire pit and, when detached, the handle may be used as a fire poker.

(52) Similar to the first pair of wheels 14, the first pair of skis may comprise a first ski and a second ski, wherein the first ski may be configured to swivel about a first axis and the second ski may be configured to swivel about a second axis. The handle may be operatively coupled to the first ski and the second ski such that the handle may be configured to swivel at least one of the first ski and the second ski. In some embodiments, the second pair of skis also comprises skis configured to swivel. At least one of the first and second pair of skis may comprise fixed (e.g., non-movable) skis. The portable fire pit with skis may also include wheels substantially similar to the first and second pair of wheels 14, 16, such that the portable fire pit may be interchangeably coupled to either skis or wheels depending on the terrain and weather conditions.

(53) Materials

(54) In some embodiments, many elements of the portable fire pit 10 are comprised of a heavy metallic material, like steel. For example, the housing 12, wheel mounts 44, the at least one vertical wall 26, the handle 48, the suspension grate 52, the grill rack 64, and the plurality of brackets 74 may be comprised of steel or a similar material. In order to enable easy movement of the cover 28/table 40, the cover 28, the at least one foldable leg 36, and the at least one handle 35 may be comprised of a more lightweight metal material, like aluminum. Specifically, each element of the table 40, including the cover 28, the at least one foldable leg 36, and the at least one handle 35 may be comprised of 6061 aluminum. In some embodiments, the grill rack 64 is comprised of aluminum or another lightweight material. The first and second pair of wheels 14, 16 may comprise permanently filled tires, such as tires filled with foam, to prevent the tires from going flat. In many embodiments, the housing 12, the first pair of wheels 14, the second pair of wheels 16, and the fire pit 22 comprise materials that are at least one of rust resistant and waterproof such that the portable fire pit 10 is configured to be positioned in a depth of water and/or snow less than or equal to about twelve inches while maintaining a fire in the fire pit 22.
