This application claims the benefit of U.S. Provisional Application No. 63/660,245, filed on Jun. 14, 1024, and U.S. Provisional Application No. 63/716,400, filed on Nov. 5, 2024, each of which application is incorporated herein by reference in its entirety.
The present technology is generally related to fire pits, and more particularly, to fire pits that are collapsible and portable.
Fire pits have become a popular “must-have” for backyard use such as for social gatherings on a summer evening, for providing some light and heat during a cook-out, or for making s′mores with the family. Often, such fire pits are permanent structures, or at the very least-they are heavy, bulky, and difficult to move. Thus, once the fire pit is constructed, the fire pit generally stays in place through the whole season of use, and often still remains in place in the off-season because of the difficulties associated with setting up the fire pit, breaking it down, if needed, or simply moving it to access the yard, such as, to mow the grass.
Conventional portable fire pits have become more prevalent in the market. Notably, fire pits have become popular for a variety of uses in a variety of locations, including at the beach, park, campsites, sporting fields, parking lots, tailgates, and the like, where the fire pit can be set-up for use, but also disassembled for transport in the user's car or truck without occupying too much storage space. However, conventional, portable fire pits are very difficult to move, especially by a single person. Additionally, such conventional portable fire pit designs are commonly very bulky and take up a lot of space, for both transport in a car and storage when not being used. As a result, there remains a need for a collapsible and portable fire pit assembly that improves upon the collapsibility and portability that is desirable for intended uses, especially uses that are temporary that would benefit from a quick assembly and quick disassembly.
Additionally, portable and collapsible fire pits must be sufficiently sturdy when assembled so as to reduce any risk during use. If a fire pit can easily fall apart when a fire has been started in the structure, it can cause the fire to spread and possibly damage the user's yard, patio, deck, or home. As a result, there is also a need for a collapsible and portable fire pit assembly that will be sturdy and safe during set-up conditions and use.
In view of the foregoing, there is a need for a fire pit assembly that can be easily set up and collapsed, especially by a single user, without requiring tremendous effort to move the fire pit assembly, to set-up and assemble the fire pit assembly for use, to break-down and disassemble the fire pit assembly after use, and all without compromising the structural integrity of the fire pit assembly when is use. Further, there is a need for such a fire pit assembly that can be set-up for use and then disassembled and collapsed when not in use with minimal effort, again, especially by a single user, without limiting or compromising the structural features of the assembly structure. Still further, there is a need for a fire pit assembly that can be easily set-up in any desirable location without compromising or affecting the safety and structural integrity of the assembly, especially on all types of surfaces, including soft ground and sand. Still further, there is a need for a fire pit assembly that provides optimal venting and air flow to increase burn time of a fire in the fire pit and to also reduce smoke emitted by a fire in the fire pit. Accordingly, it is a general object of the present invention to provide a portable and collapsible fire pit assembly that overcomes the problems and drawbacks associated with prior art fire pit structures, and therefore significantly improves the utility of such a fire pit while permitting easy transportation and/or storage in a collapsed condition.
The present disclosure addresses these issues and provides a means to circumvent the associated drawbacks of such conventional fire pit designs.

Embodiments of the present disclosure include a portable and collapsible fire pit (100). The fire pit (100) can move between a deployed or standing configuration (170) (shown in FIGS. 1A and 23) for use and a collapsed or packed down configuration (172) (shown in FIG. 9) for transportation and storage. The fire pit (100), when in the collapsed configuration (172) is easy to store and transport to different locations, which enables the use of the fire pit (100) in locations in which a fire pit may be difficult to install or is undesirable to have. For example, the fire pit (100) can be used as a fire pit on a beach for a day, then transported and stored in the collapsed configuration (172). The fire pit (100) is not limited to the use cases and examples described herein. The fire pit (100) is also designed to improve air flow and reduce smoke during use.
Turning to the Figures, FIG. 1A illustrates a tilted view of the fire pit (100) and FIG. 1B illustrates a partial exploded view of the fire pit (100). A set of feet (128) are not shown in FIG. 1B for clarity. The fire pit (100) includes a body (102), a base (104), and a retention rim (106). It will be appreciated that in some embodiments the fire pit (100) may not include the base (104) and/or the retention rim (106). As shown, the fire pit (100) is cylindrical in shape and circular when viewed from a top of the fire pit (100). In other embodiments, the fire pit (100) may be any shape when viewed from the top of the fire pit (100) such as, for example, triangular, square, oval, rectangular, hexagonal, polygonal, or any other geometrical shape. The fire pit (100) may also have any number of sides such as, for example, 12 sides, 20 sides, etc. The fire pit (100) may have an inner circumference of, for example, 46″ inches. In other embodiments, the fire pit (100) may have an inner circumference of less than or greater than 46″.
The body (102) may include at least one handle (126) for positioning, picking up, or otherwise moving the body (102). The body (102) is formed from a set of slats (108) and each slat (108) is formed by an outer slat (110) and an inner slat (112), as will be discussed in detail below.
Turning to FIGS. 2A and 2B, a front view and a top view of the outer slat (110) are respectively shown. In the illustrated embodiment, the outer slat (110) has a slightly arcuate shape and a pair of flanges extending towards the inner slat (112) when viewed from the top. In other embodiments, the outer slat (110) can have any shape when viewed from the top.
Turning to FIGS. 3A and 3B, a front view and a top view of the inner slat (112) are respectively shown. In the illustrated embodiment, the inner slat (112) is planar and has a rod (114) at one end and a receiver (116) at the other end. The receiver (116) can receive the rod (114) of an adjacent inner slat (112) to form a connection (118) (shown in FIGS. 4, 5, and 6) between adjacent inner slats (112). In the illustrated embodiment, the receiver (116) is a barrel that can receive the rod (114). It will be appreciated that the connection (118) between adjacent slats (108) can take any form, including various embodiments described below.
Turning to FIGS. 4, 5, 6, and 7 a top view, a detailed top view, a tilted, detailed top view, and a tilted, detailed bottom view of the body (102) are respectively shown. The base (104) and the retention rim (106) are not shown for clarity. As shown, the inner slat (112) and the outer slat (110) form the slat (108), which has a cavity (164), shown and described in detail in FIG. 18.
As previously described, the slats (108) are connected together at the connection (118). The connection (118) can be a limited connection (120) in which the inner slats (112) have a limited range of pivot motion (e.g., within, for example, 10 degrees or less) or an unlimited connection (122) in which the inner slats (112) can pivot to any degree. In general, the connections are designed to facilitate set-up and break-down of the body (102). More specifically, the limited connection (120) is limited by a tab (124) extending from the receiver (116). In the illustrated embodiment, the tab (124) extends a length of the inner slat (112). In other embodiments, the tab (124) may extend a short distance along the inner slat (112), as shown in FIG. 7. Further, the tab (124) facilitates set up of the body (102) in that the tab (124) can guide the slats (108) into the circular shape (or any other shape of other embodiments of the body (102)) when moving to the standing configuration. It will be appreciated that in other embodiments, the limited connection (120) may be limited in any manner.
Turning to FIGS. 8 and 9 (and with reference to FIGS. 2A-7), a configuration of unlimited connections (122) and limited connections (120) and the body (102) in the collapsed configuration are respectively shown. The unlimited connection (122) is shown and labelled in FIG. 6. The unlimited connection (122) is formed by a series of hinges (175) on adjacent slats (108) connected by a rod. The unlimited connection (122) enables the adjacent slats (108) to rotate or pivot to any degree. As shown in FIG. 8, the body (102) includes two unlimited connections (122) on opposing sides of the body (102) and limited connections (120) in between the two unlimited connections (122). The two unlimited connections (122) are also spaced 90 degrees from two handles (126), though in other embodiments the body (102) may have any number of handles, unlimited connections, and any configuration.
The two unlimited connections (122) spaced on opposite ends facilitate moving the body (102) between the collapsed configuration and the standing configuration. More specifically, the two unlimited connections (122) enable the body (102) to be collapsed at the two unlimited connections (122) such that the body (102) folds flat onto itself. In other words, the body (102) can be folded flat such that the slats (108) form two rows of slats (108) with one row of slats (108) resting on top of the other row of slats (108).
The illustrated configuration enables the body (102) to be folded flat, as shown in FIG. 9, for transportation and/or storage. The body (102), the base (104), and the retention rim (106) can be inserted into and stored in, for example, a bag. Further, the inner slats (112) being planar facilitate a low profile of the body (102) when the body (102) is in the collapsed configuration (172). In the embodiment illustrated, the body (120) is made up of layers of equal number of slats (108). In alternate designs, the slats (108) can be collapsed in an aligned array designed to reduce the footprint of the collapsed body (102). When the body (102) is collapsed, the slats (108) remain connected by, for example, the connection (118) and/or a mechanical tension mechanism (136), as described below. By remaining connected during collapsing and storage, the slats (108) can easily be set up again and moved to the standing configuration.
Turning to FIGS. 10 and 11, a top, tilted view of the base (104) and side, cross-sectional view taken along line A-A are respectively shown. The base (104) is preferably constructed of the same material as the body (102). In other instances, the base (104) can be a different material than the body (102).
In the embodiment illustrated in FIG. 10, the base (104) has a base body (138) and a base pan (140). The base body (138) is circular in shape and has a diameter slightly larger than a diameter of the body (102). A larger base (104) ensures greater stability in the standing configuration, so that when in use, the risk of the assembly fire pit (100) tipping over is greatly reduced. The base body (138) also includes a sidewall (142) that extends up and is configured to provide support to hold the body (102) within the base (104), as shown in FIG. 1A. In the illustrated embodiment, the base (104) also contains a channel (144) that runs the outer circumference of the base body (138), allowing the bottom of the body (102) to fit securely in the channel (144) and retaining its desired circular shape when set-up. The channel (144) also helps reduce the risk of the body (102) shifting or collapsing when in use.
As shown in FIG. 11, the base pan (140) can be a frusto-conically shaped base pan (140). Additionally, the base (104) forces side wall alignment (for the body (102)) upon installation, and further, can maintain the set-up shape and volume of the body (102) during use of the fire pit (100).
In the illustrated embodiments, the base (104) is independent of the body (102), and can be removed to facilitate set-up, cleaning, transport and storage of the fire pit (100). In alternate embodiments, the base body (138) may be foldable in half by means of a one direction hinge system (not shown) so as to reduce the footprint of the base (104) for storage and transport. In other embodiments, the base (104) may be connected to the body (102) and the body (102) may be configured to fold over the base (104) when in the collapsed configuration.
In general, the base (104) serves as a collection for any ash, burnt wood, coals, or any other debris. Removal of such debris is simplified by merely removing the body (102) and cleaning the surface of the base body (138) and/or the base pan (140).
Turning to FIG. 12, a tilted, cross-sectional view of the fire pit (100) is shown without the base pan (140) and one of the inner slats (112) for clarity. As shown, the body (102) can include a locking element (146) that secures the body (102) in its set-up condition to the base (104) and more specifically to the base body (138) and the base pan (140) during use. The locking element (146) can include a spring-loaded lever that acts as a lock for the set-up fire pit (100). When the locking element (146) is engaged between the base body (138) and the base pan (140), a user can lift and move the fire pit (100) without needed to disassemble the parts. In use, the locking element (146) also acts as a quick-release to disengage the body (102) from the base (104) when the user wants to collapse the fire pit (100).
As shown, the body (102) also includes the handle (126) positioned above the locking element (146). The body (102) also includes a button (145), shown in FIG. 15, to actuate the locking element (146). The button (145) may be, for example, a push button. The position of the handle (126) can provide aid in actuating the button (145) to actuate the locking element (146).
The base (104) further includes support feet (128) (shown in FIGS. 1A, 12, and 15) that collectively raise the entire fire pit (100) off the ground. This is desirable when using the container (100) on certain surfaces, such as uneven ground, sand, wet grass or mud. Raising the set-up container (100) off the ground is also advantageous for certain intended uses of the container (100), including as a fire pit, where raising the container (100) off the ground can improve air flow into the container (100) through vents formed into the base pan (140). Similarly, when used as a cooler, the container (100) can include a plug on the base pan (140) to drain excess water. Similarly, as noted herein, the container (100) can be used as an article of furniture, such as a table or stool, where it may be desirable to raise the container (100) off the ground.
The support feet (128) can be moveable between a deployed configuration and a stored configuration. The support feet (128) raise the base (104) (and thus the fire pit (100)) when in the deployed configuration. The support feet (128) can be foldable, removable, fixed, adjustable, or the like. In the illustrated embodiments, the support feet (128) comprise three folding legs that can be folded up for storage, or even removed, as desired. The support feet (128) can include various embodiments such as, for example, a plurality of support feet (128) spread around the circumference of the base (104), a support ring extending around the entire circumference of the base (104) that elevates the body (102) while maintaining stable contact with the ground surface, and support feet (128) which can be folded up about a hinge and stored under the base (104) when not in use. The support feet (128) can also be biased towards a set up configuration and a packed down configuration. In such embodiments, the bias can be, for example, a spring bias. Such bias aids in setting up or packing down the support feet (128).
Turning to FIGS. 13 and 14, a top, tilted view and a bottom, tilted view of the retention rim (106) are respectively shown. In some embodiments, the retention rim (106) is constructed of the same material as the body (102) and the base (104). In other embodiments, the retention rim (106) can be constructed of a different material than the body (102) and/or the base (104). As illustrated, the retention rim (106) is generally circular in shape to complement the shape of the body (102) in the standing configuration (170). More particularly, the retention rim (106) comprises a rim body (148) defining a central opening (150). In the illustrated embodiment, the retention rim (106) has a diameter that is equal to that of the base (104), again to mitigate any risks of the fire pit (100) tipping over during use. In some embodiments, the retention rim (106) can include a channel (154) that runs the outer circumference, allowing the top of the body (102) to fit securely in the channel (154), which assists in maintaining the set-up shape of the body (102). The retention rim (106) also includes a sidewall (152) that extends over a top of the slats (108) and helps hold the retention rim (106) on the body (102).
In an alternative embodiment, the retention rim (106) can be provided with a locking element that secures the body (102) in its set-up condition, especially during use. The locking element can be used in conjunction with one or more carry handles provided on the retention rim (106) which provides leverage for securing the locking element. The one or more carry handles can also act to dissipate heat so that the unit can be carried safely without risk burning injury.
In the illustrated embodiment, the retention rim (106) is independent of the body (102), and can be removed to facilitate set-up, cleaning, transport and storage of the fire pit (100). Like the base (104), the retention rim (106) may be foldable in half by means of a one direction hinge system (not shown) to reduce the overall footprint of the fire pit (100).
Turning to FIGS. 15-18, an air flow and venting of the fire pit (100) is shown. FIG. 15 shows a side view of the fire pit (100), FIG. 16 shows a side cross-sectional view of the fire pit (100) along line C-C(of FIG. 17), FIG. 17 shows a top view of the fire pit (100), and FIG. 18 shows a top cross-sectional view of the fire pit (100) along line B-B (of FIG. 15).
As shown, each slat (108) has the inner slat (112) and the outer slat (110), which together define the cavity (164), shown and labelled in FIG. 18. Each slat (108) also includes at least one first vent (166) positioned towards a top of the inner slat (112) (e.g., towards the retention rim (106)) and at least one second vent (168) positioned towards a bottom of the outer slat (110). The first vent (166), the second vent (168), and the cavity (164) assist with air intake and heat flow and distribution during use of the fire pit (100).
More specifically, the body (102) utilizes a proprietary TubeFlow™ technology that guides air intake from below the raised base (104), into a burn chamber (168) defined by an interior volume of the body (102) when in the standing configuration. The air intake from below the base (104) is enabled by the feet (128), which hold or raise the base (104) above a ground surface so that the air intake can enter the base (102) from below the base (102).
During use, the air intake can enter into the burn chamber (168) of the body (102) through vent holes or perforations (142) provided in the base pan (140) (shown in FIG. 18) in a first burn flow (160). A second burn flow (162) can be created with air flow from the burn chamber (168) exiting through the perforations (142) in the base pan (140) and flowing up within the cavities (164) formed within individual slats (108). The first vent (166) in the inner slat (112) supports such secondary burn with recirculated air flowing back into the burn chamber (168) via the vent first (166). The second vent (168)—i.e., formed in the outer slat (110)—similarly supports ambient heat and facilitate heat dissipation. Further, active convection pulls heat away from the outer slat (110).
The perforations (142) in the base (104) can also create a measurable draft of air flow that would burn off any excess smoke normally expelled through the top of the fire pit (100). Such draft would reduce the overall amount of smoke and make the fire pit (100) more enjoyable for those sitting or standing in its vicinity. Further, the shape of the base pan (140) may also align with vent holes (168) provided in a lower portion of the body (102), which facilitates distributing heat and drawing excess smoke away from a user.
The outer slats (112) can be constructed from aluminum, stainless steel, ceramic, glass, or any sufficiently inflammable or flame retardant material (such as a treated plastic or wood). In embodiments where the outer slats (112) are aluminum, the outer slats (112) can be treated with anodization, thin film vapor deposition, plating and other finishes previously unachievable in the category. In some embodiments, a heat reflective material can be applied on the outer slat (108) and/or the interior slat (108) to reduce the temperature applied to the slats (108). In some embodiments, the heat reflective materials can be applied as a substrate facing the cavity (164). Such heat reflective material allows for use of a wider range of materials and surface coating for the exterior slats (108) given the reduced heat exposure.
The inner slats (110) forming the body (102) can be constructed using an insulation that radiates heat inwards towards the burn chamber (168), thereby improving interior burn and protecting the outer slats (112) from overheating. The insulation of the inner slats (110) can also be increased with the heat reflective material applied to the outer surface of interior walls formed by the inner slats (110).
Turning to FIGS. 19 and 20, an alternative design of the body (102) and an alternative design of the retention rim (106) are respectively shown. As shown in FIGS. 19 and 20, an upper portion of the body (102) and the retention rim (106) are provided with formed shapes (170) to channel rising air into a circular pattern, thereby generating a vortex effect distributing the heat but also drawing any residual smoke towards the center of the fire pit volume instead of outside the fire pit assembly. The formed shapes (170) comprise angled flaps formed on both the interior of the body (102) and the retention rim (106). These flaps can be coordinated so that the retention rim (106) easily fits onto the body (102) for assembly. In some embodiments, the formed shapes (170) can be provided only on the body (102), or only on the retention rim (106). In other embodiments, the formed shapes (170) can be distributed between the body (102) and the retention rim (106)—such as alternating, or more on one part than the other, or evenly or unevenly distributed around the circumference of one or both parts.
Turning to FIG. 21, a method for setting up a fire pit such as the fire pit (100) is provided. In a step (2100), a base such as the base (104) is positioned at a desired location. The step (2100) may include moving a set of support feet such as the set of support feet (128) from a folded configuration and a deployed configuration. In a step (2102), a body such as the body (102) of the fire pit may be moved from a collapsed configuration such as the collapsed configuration (172) to a standing configuration such as the standing configuration (170). Once in the standing configuration, the body can be positioned on the base in a step (2104). Then a rim such as the rim (106) may be positioned on the body opposite the base to complete setting up the fire pit. In some embodiments, the method may include actuating a locking mechanism such as the locking mechanism (146) to lock the body to the base and/or the rim.
It will be appreciated that the method described in FIG. 21 may be performed in the reverse steps to move fire pit from a standing position to a collapsed and packable configuration.
Embodiments of the present disclosure described above include a portable and collapsible fire pit. As described above, the fire pit can beneficially move between a deployed or standing configuration for use and a collapsed or packed down configuration for transportation and storage. The fire pit is also beneficially easy to store and transport to different locations, which enables the use of the fire pit in locations in which a permanent structure may be difficult to install or is undesirable to have. The fire pit is also structurally designed to support a fire while remaining portable. The fire pit also includes features to improve air flow and reduce smoke to enhance a user's experience.
