Description

The invention is described in the following statement: 2025201594   05 Mar 2025 A SYSTEM AND APPARATUS FOR FORMING A PORTABLE CAMP FIRE FOR CAMPING AND RECREATIONAL USE Field of the Invention 5

[0001] The present invention relates to a system and apparatus for forming a portable camp fire or fire pit at or close to ground level for camping and recreational use. In particular the present invention relates to an improved portable fire pit assembly which controls the direction of flames and radiant heat and is effective for substantially minimizing smoke. 10

[0002] The invention has been developed primarily for use in / with a system and apparatus for forming a portable camp fire or fire pit at ground level for camping and recreational use and will be described hereinafter with reference to this application. However, it will be appreciated that the invention is not limited to this particular field of 15 use. Background of the Invention

[0003] One of life’s pleasures involves recreational camping and generally spending time outdoors. Sitting about and looking into a camp fire in an evening is a simple yet 20 mesmerising pleasure whether alone or in the company of friends and family. People enjoy cooking over an open fire whether camping or outdoors in a domestic setting, and of course the fire may also provide cosy warmth and an ambient light source.

[0004] Quite often, outdoor fireplaces are used on decks or on porches made of wood 25 or concrete, that can be readily discoloured or damaged when exposed to elevated temperatures. Prior art fire pit structures contribute to this problem by allowing radiant transfer of heat to the underlying surface.

[0005] A fire pit is traditionally a pit dug in the ground to contain fire and prevent it from 30 spreading while being used for cooking and heating. More recently, as a means to avoid the need to dig a hole in the ground, fire pits have been fabricated from bricks, concrete or metal, which are configured to form a substantially enclosed receptacle that can be supported in the ground or on legs. 2025201594   05 Mar 2025

[0006] A particular drawback of outdoor ground level wood fuelled Camp Fire Pits, is that they are notoriously smoky and odorous environments. This can detract from an otherwise cosy and pleasant experience. There is therefore a need for an improved campfire to enhance outdoors experience. 5

[0007] The creation of smoke can be minimised to some extent by stacking wood in a manner to create plenty of air gaps, or by standing wood pieces more upright (for example in a tee-pee bonfire type shape). However, it is difficult to maintain this type of structure as the fire burns down and the new wood is added because the wood io becomes somewhat starved of air by the build-up of ash and coals. Also, even when short logs are added to a burning fire, smoke generally comes from the colder ends of the wood because these parts have often yet to reach the higher burning temperature.

[0008] A further problem with conventional fire pits is that much of heat generated is 15 exhausted upwards and outwards and therefore less effective in providing warmth for multiple people at the same time. One way of addressing this is to provide a large fire requiring greater wood fuel consumption, however large structures become unwieldy and less portable. Further, large fire pits cannot be readily moved once they are alight -this may become a problem if the direction of wind changes. 20

[0009] The present invention seeks to provide an improved fire pit, which will overcome or ameliorate at least one or more of the deficiencies of the prior art, or to at least provide an alternative. It is to be understood that, if any prior art information is referred to herein, such reference does not constitute an admission that the information forms 25 part of the common general knowledge in the art, in Australia or any other country. Summary of Invention

[00010] According to a first aspect of the present invention, there is provided a system and apparatus for forming a portable camp fire for camping and recreational use 30 comprising: a base for supporting a fire spaced above the ground; at least one wall detachably mountable to the base and to form a surround of at least half of the base but less than the whole base wherein the portable camp fire has at least a partial front opening. 2025201594   05 Mar 2025

[0011] The present invention provides an advance over the prior art as it reduces smoke generation by substantially continuously allowing sufficient air ingress into the base of the fire unlike the prior art wood fuelled fire pits. In addition, the front opening allows radiant heat exposure to people sitting or standing about the front end and sides 5 of the camp fire. The portable camp fire allows one or more people who wish to extend their day in the outdoors to well into the evening substantially without a smoky and odorous environment.

[0012] The base and at least one wall are formed of interconnecting panels. Preferably io each of the interconnecting panels substantially comprise of one or more substantially flat planar sections. Preferably each of the interconnecting panels can include one or more slots or openings for ventilation. The interconnecting panels can include one or more engaging means for slidably interlocking without tools, hinges or threaded fastenings. 15

[00113] The system and apparatus for portable camp fire can include a back panel and the base forming an L-shaped open front retaining structure forming the portable camp fire. The back panel can include a relatively high back compared to at least part of the side wall wherein a fire in portable camp fire is tending to extend the fire in a 20 vertical direction to form a vertical fire. This takes advantage of a fire’s natural inclination to climb. The back panel can further include ventilation slots in a low area above the height of the base forming the portable camp fire off ground. Preferably the wall has ventilation slots in a low area above the height of the base forming a portable camp fire off ground. Preferably the space between the base and the grounds can vary 25 and is preferably close to the ground.

[0014] In one embodiment the wall is formed of two substantially planar L-shaped panels that are spaced and connected to opposite sides of the back panel to form the surround. In a related embodiment, the back panel can include a stepped portion 30 extending across the panel and a series of spaced apart ventilation slots disposed on either side of the stepped portion. The combination of stepped portion and ventilation slots allows placement of one or more wood pieces against the back panel with the stepped portion creating an air gap for convection. Preferably the device provides a flat pack kit for forming a portable camp fire. 2025201594   05 Mar 2025

[0015] In a related aspect of the present invention, there is described an assembly for forming a portable camp fire for camping and recreational use comprising: two substantially planar L-shaped panels forming spaced side walls; a back panel being a relatively high back compared to at least a front part of the two substantially planar L-5 shaped panels forming the spaced side walls, wherein the back panel includes an intermediate lateral stepped portion and ventilation openings on either side of the stepped portion to allow location of wood pieces upright against the back panel and create air gaps for promoting a vertical fire and minimising smoke; a base panel interfitting with the two substantially planar L-shaped panels and the back panel, the base io panel adapted to support a fire spaced above the ground and including a planar portion and a forward upturned edge portion forming a coal retaining area and providing an open frontal area for forward funnelling of radiant heat; wherein in an assembled condition the back panel and the planar portion of the base panel are located at an obtuse angle relative to each other; wherein the two substantially planar L-shaped 15 panels include a series of holes and / or slotted openings adjacent to the planar base portion of the base panel to allow air ingress at the base.

[0016] The planar portion of the base panel can have a trapezoidal configuration upon which the fire is supported. The planar portion can also include a series of holes so 20 that after the fire has died, there are very little unburnt coals remaining to be disposed of. Preferably the forward upturned edge portion of the base panel is angled to the planar portion, preferably at an obtuse angle, providing at least a partial open front or forward portion of the camp fire to direct radiant heat forward. 25

[0017] The upturned portion also serves as a rest for long logs and a barrier to retain coals within the confines of the base panel. The forward upturned edge portion of the base panel and opposite forward portions of the side walls can include mating engagement elements to allow inter-fitting of the base panel and the side walls. The mating engagement means can include an opening on a forward end portion of the 30 side walls and opposite flange members on the upturned edge portions. The openings on the forward end portions of the side walls can further include a recess portion for releasably locking the opposite flange members of the upturned edge portion with the side walls in an assembled condition. 2025201594   05 Mar 2025

[0018] The flange members on the upturned edge portion of the base panel can be laterally projecting C-shaped lugs which are configured to inter-fit with the mating openings in the side walls. The side walls can include ventilation openings along on a lower portion so that in an assembled form the openings extend at or adjacent the 5 base panel to allow ingress of air at or close to the base of coals formed on the base panel. The back panel can include includes a bottom flange extending therefrom forming a seat adapted to receive a rearward end section of the base panel thereon in assembly. io

[0019] In a further related aspect of the present invention, there is described an assembly for forming a portable camp fire for camping and recreational use comprising: two substantially planar L-shaped panels forming spaced side walls; a back panel being a relatively high back; a base panel having a trapezoidal shaped planer base platform with a plurality of holes therein upon which the fire is supported 15 and a front upturned integral panel being relatively low; wherein the back panel includes an intermediate lateral stepped portion and ventilation openings above and below this stepped portion to allow location of wood pieces standing semi upright against the back panel and create air gaps for promoting a vertical hot fire and minimising smoke; wherein the back panel and rear portions of the side walls include 20 mating engagement means comprising a split arrow head shaped slots on side walls and laterally projecting ‘T’ shaped lugs on opposite sides of the back wall to allow releasable assembly of the side walls and back wall; wherein a bottom edge portion of the back panel projects forwardly from the back wall at an obtuse angle so as to provide a locating seat support for a rear portion of the base panel in an assembled 25 condition; wherein the forward upturned edge portion of the base panel and opposite forward portions of the side walls include mating engagement elements to allow interfitting of the base panel and the side walls; wherein the side walls include feet members for supporting the base panel from the ground; and wherein in an assembled condition, the assembly provides a radiant heat directional control forwardly towards 30 the at least partially open front.

[0020] This low front upturned panel can serve as a log rest and coal retaining guard and provides a relatively large open frontal area for forward funnelling of radiant heat at a relatively low level. The low elevation of the front upturned panel section can also 2025201594   05 Mar 2025 incorporate at each side laterally projecting ‘C’ shaped lugs designed to inter-fit with mating elements in each of the two side wall panels. Both back and front panels interfit with the two identical substantially planer L-shaped side panels; which include a series of slotted openings to allow adequate and continually uninterrupted air ingress 5 to the fire.

[0021] Advantageously, wood pieces can be stood upright or semi-upright in a rear section against the back panel allowing air to freely flow about the pieces of wood. The wide open frontal area permits easy air flow in from the front. Additionally, the io ventilation slots in side panels close to the planar base portion of the base panel also allow substantially unobstructed air flow and therefore allow more complete combustion. The holes in the planar base of the base panel provide a means such that after the fire has died, there are very little unburnt coals remaining to be disposed of. 15

[0022] The structure of the assembled fire pit results in virtually smokeless combustion because the full length of each piece of wood added to the upright fire - catches alight quickly and is heated more evenly along its length thus limiting smoke emissions from the log ends to a minimum. These advantages represent clear improvements over the prior art. The back panel is preferably narrow compared with the upturned panel of the 20 base panel. The narrow and relatively high rear panel provides more efficient heating. The lateral step portion in the back panel acts as a small step to lean small sticks against it when lighting a fire and also, so that a small continually flaming fire can be maintained when cooking. The present assembly provides a small fire option for cooking utilising 6 or 8mm diameter steel cross bars or the like, resting in the ‘V’ slots 25 incorporated in the high and low level top edges of the side panels.

[0023] The two substantially planar L-shaped panels forming side walls can include a high rear portion adjacent the back panel, and a stepped down portion towards the front end thereof to provide an open frontal end with the base panel. Preferably the 30 side walls diverge from rear to front of the assembly such that the forward portions of the side walls are wider apart than the back. This structural feature assists in stabilising the assembly to provide a narrow semi confined vertical series of hot flames. Therefore the structure formed by the assembly encourages radiant heat to be directed more 2025201594   05 Mar 2025 outwards at ground level in an arc of approximately 90 degrees. This is more efficient in warming people’s knees and feet because heat is directed lower down to the ground. Preferably the back panel includes a bottom flange extending therefrom adapted to receive an end section of the base panel thereon in assembly. Preferably the base 5 panel is trapezoidal so that a forward portion is wider that the rear portion. The base panel, rear panel and the two substantially planar L-shaped panels forming side walls, can include inter-engaging means allowing connection to form a base off the ground and a surround without the need for tools, hinges or threaded fasteners. 10

[0024] In one embodiment, the inter-engaging means can include: split arrow head shaped slotted recesses in the high rear portion and the stepped down portion towards the front end thereof of the two substantially planar L-shaped side wall panels, and ‘T’ and ‘C’ - shaped lugs incorporated in and projecting laterally from the front upturned portion of the base and back panels, and wherein the lugs are adapted to slide into 15 the ‘V’ slots or split arrow head shaped slots of the side panels, and wherein the back panel is rotated about 30 degrees towards the rear to lock the assembly in place. The inter-engaging ‘lug -in - slot’ system, provides a stable assembly such that it can safely support a BBQ plate and most typical camping utensils. 20

[0025] Similarly, disassembly can be easily achieved by rotating the back panel forwards. The obtuse angular positioning of the back panel with respect to the base panel allows this forward rotation to cause sliding disengagement of the base plate from a seated condition on the bottom flange of the back panel. Preferably the assembly can include a holding tray located on the ground underneath the assembly. 25 Therefore, when the back panel is disengaged from the side panels / walls and the back panel removed, residual ash coals can be emptied onto the holding tray for easy disposal of the residual ash and charcoal. Preferably the tray is adapted to hold a volume of water so that if the assembly is used on a grassed surface, the grass below the assembly is less likely to overheat and die. This is because the water continues to 30 evaporate and results in a cooling effect so long as water is maintained in the holding tray.

[0026] Preferably the panels are fabricated from Stainless Steel. This minimises rusting overnight due to overnight moisture condensation and only requires minimal 2025201594   05 Mar 2025 brushing next day to remove carbon deposits. If need be, the panels can be washed in a standard sink or being made of stainless steel can even processed through a conventional domestic dishwasher. Preferably the interlocking panels are made by laser cutting light weight, heat resisting Stainless Steel or mild steel. Preferably mild 5 steel is an alternative material that can be utilised, however it is appreciably weaker than Stainless steel, particularly at elevated temperatures but can be substituted if thicker (thus heavier) is acceptable and if the resulting dirty and rusty surfaces can be tolerated. io

[0027] Preferably the two substantially planar L-shaped side wall panels include arcuate slots in the high rear portions thereof to allow insertion of hands for manoeuvrability of the assembly. When the assembly is cold, it can easily be lifted by inserting hands in the hand- hold slots near the top of both side panels. The stability of the assembled structure allows the assembly to be held with one hand and it will 15 remain assembled. If the fire is alight, two people can move it to another location by lifting it together using hooked pegs or the like. This feature has proven to be most useful should the fire need to be moved to suit changes in the camp site layout.

[0028] Alternatively, if the fire pit is resting on the holding tray, it can be towed about 20 on the ground using modified tongs or a shaped hooked poker or the like to allow engagement with openings on the high end of the side walls. Preferably the panels are adapted to lay substantially flat onto the holding tray for space savings and to allow easy pack-up by sliding into a carry bag. The resulting kit forms a thin (70mm) flat pack in a carry bag, which takes up minimal space for travelling. 25

[0029] In a related aspect of the present invention, there is described a method of providing vertical fire in a portable camp fire including the steps of: providing a plurality of predefined panels elements having interengaging means allowing connection to form a base above but close to the ground and a surround without the need for tools, 30 hinges or threaded fastenings; providing at least one an elongated high back panel; providing ventilation channels in the panels at a low position but above the height of the base to vent the fire supported on the base; allowing placement of elongated combustible material in a substantially vertical direction alongside the elongated high back panel for tending to extend the fire in a vertical direction to form a vertical fire. 2025201594   05 Mar 2025 Preferably the kit assembly weighs less than 5Kg and disassembles into a flat pack for convenient carrying in a suitable carry bag. This makes the assembly safe to handle, pack and transport. 5

[0030] In the method the high back panel and base can form an L-shaped open front retaining structure forming the portable camp fire. Preferably the high back and low level front retaining structure with ventilation slots in low area above the height of the forming a portable camp fire off ground. Preferably the step of intergaging means allowing connection to form a base off the ground and a surround without the need for io tools includes the use of‘T’ and ‘C’ shaped lugs incorporated in the back panel and front upturned portion of the base panel, and which slide into the split arrow head shaped slots of the side panels wherein the back panel and front upturned portion of the base panel are rotated about 30 degrees towards the rear to secure them into place. 15

[0031] In a further related aspect of the invention there is described a flat pack kit for forming a portable camp fire comprising: two substantially planar L-shaped side panels forming spaced walls; back panel being a relatively high back compared to at least a front part of the two substantially planar L-shaped side panels forming spaced walls; 20 a base panel having a trapezoidal planar plate portion and a front upturned portion thereof for interfitting with back panel and / or wall panels wherein the back panel and the base forming an L-shaped open front retaining structure with the base supported off ground. 25

[0032] The panels can have slots and intergaging means allowing connection to form the base above but close to the ground and the surround without the need for tools or threaded fastenings and can further include the use of ‘T’ and ‘C’ shaped lugs incorporated in the front upturned portion and the back panel, and which slide into the split arrow head shaped slots of the side panels wherein the back and front upturned 30 portion panels are rotatable about 30 degrees towards the rear to secure the assembly in place.

[0033] The flat pack kit for forming a portable camp fire can include ventilation channels in the panels at a low position but above the height of the base to vent the 2025201594   05 Mar 2025 fire supported on the base. In this embodiment, the assembly can be adequately held together by T and ‘C’ shaped lugs that slide into, drop downwards and then are rotated into a curved part of the half arrow head slots to provide a self-locking mechanism. 5

[0034] The apparatus can further include a shaped grate mountable by the rear panel and base panel, wherein the grate is substantially planar and includes a series of holes and / or slotted openings and is mounted spaced from the base panel to support a fire above the base panel and to allow fine ash to fall through the slotted openings therein io received by the base panel. An advantage of having a grate is that openings on the opposing side panels can be maintained substantially free from build-up of ash and coals during a fire that otherwise could stifle sufficient air flow to sustain the fire.

[0035] The rear panel can include a stepped portion intermediate a lower portion and 15 an upper portion. The lower and upper portions of the rear panel can comprise a series of vertically oriented openings and the stepped portion provides a buffer to substantially maintain a spacing between a log or piece of wood resting against the rear panel and the vertically oriented openings in the upper and lower panel portions. The lower portion of the rear panel and grate can include interconnecting structures to 20 assist secure the grate to the rear panel. The interconnecting means can include: a lateral opening in at least one of the vertical oriented openings in the lower portion of the rear panel; and one or more flange elements extending rearwardly of a rear edge portion of the grate, wherein the one or more flange elements is located to be received by the lateral opening in the one or more vertical oriented openings in the lower portion 25 of the rear panel.

[0036] The grate can include a plurality of spaced flange elements extending rearwardly from a rear edge location thereof, wherein the flange elements are adapted to be received through a lateral opening in a corresponding plurality of the vertically 30 oriented openings in the lower portion of the rear panel. In an assembled condition, the flange members of the grate can extend through the lateral opening in the rear panel to sit proud of the rear panel. Preferably one or more of the flange elements of the grate can include an opening therethrough to receive a releasable locking pin, 2025201594   05 Mar 2025 lynch pin or ring clip behind the rear panel, thereby releasably securing the grate to the rear panel.

[0037] The rear panel can further include a seat portion extending forwardly from a 5 lower end portion thereof and extending across the width of the rear panel. The seat is adapted to receive a rearward portion of the base panel thereon in a seated condition. The seat and base panel can include interconnecting structures thereon to assist secure the base to the rear panel. The interconnecting means can include a slotted opening in the seat and a tab extending beneath a rear portion of the base io panel, wherein the slotted opening in the seat is located to receive the tab. Preferably the tab can include an opening therethrough for receiving a releasable clip or pin which retains the base in a seated condition while the apparatus is in use.

[0038] The base panel can include a downwardly extending tab adjacent the rearward 15 end thereof, and the seat can include an opening therein to receive the tab in an assembled condition such that the tab extends below the level of the seat. The tab can further include an opening therein to receive a locking pin, lynch pin or ring clip beneath the base panel to releasably securing the base panel to the rear panel. In this embodiment, any accidental disengagement of panels is minimised by the 20 interconnecting members and locking pin, when an excessive downwards directed pressure is applied to the apparatus.

[0039] The base panel can further include an upturned lateral portion extending from a forward location of the planar portion. The upturned portion of the base panel can 25 act as a forward stop for placement of wood or logs so that a long piece of wood can be propped against the rear panel while the upturned portion minimises or controls forward displacement. The upturned portion of the base panel and the grate can include interconnecting structures that allow releasable engagement of front end portions thereof. The interconnecting structures can include at least one flange 30 element extending from the upturned portion and a corresponding slotted opening(s) in a forward portion of the grate, wherein the at least one flange element extending from the upturned portion of the base panel is adapted to be received by the slotted opening in the grate. Therefore, in an assembled condition the at least one flange element of the forward upturned portion of the base panel is received in a 2025201594   05 Mar 2025 corresponding opening in a forward portion of the grate. Preferably the flange element(s) extend through the forward opening(s) in the grate and thereby extend above the plane of the grate. In this condition, the flange elements sitting proud of the grate can act as propping points for semi-vertical placement of wood in a fire. 5 The apparatus can further include a holding tray. The holding tray can be adapted to receive a volume of water therein. Preferably the holding tray receives the assembled apparatus therein and the water acts as an insulator between the apparatus and a support surface. io

[0040] In a related aspect of the present invention there is disclosed an assembly of substantially planar parts for forming a portable camp fire for camping and recreational use including: a plurality of interconnecting components comprising: a base panel; a rear panel; opposite side panels; and a grate; wherein the rear panel and opposite side panels include releasable mating engagement members comprising a first and 15 second flange elements extending laterally of opposite side edge portions of the rear panel and arrow head slotted opening on a rear portion of the side panels wherein the arrow head slotted openings define an insertion and release location in a first orientation and an engaged location in a second orientation for the first and second flange elements; wherein the rear panel includes a seat at a lower end portion thereof 20 for receiving a rear portion of the base panel thereon; wherein the grate and the rear panel comprise releasable mating structures comprising one or more spaced apart lateral slotted openings in the rear panel and corresponding shaped tabs extending from a rear edge portion of the grate adapted to be received by the lateral slotted openings in a substantially horizontal orientation; wherein the base panel and grate 25 comprise releasable mating components having at least one forward located opening in the grate and at least one upturned flange element extending from the base, the upturned flange adapted to be received through the at least one forward located opening, wherein the at least one flange element extends through the at least one forward located opening in the grate and above the plane of the grate; wherein the 30 base panel and opposite side panels comprise releasable mating structures including: oppositely disposed flange elements extending laterally from opposite side edge portions of the base panel and oppositely disposed arrow head slotted openings on a forward portions of the respective side panels; wherein the arrow head slotted openings define an insertion and release location in a first orientation and an engaged 2025201594   05 Mar 2025 location in a second orientation for the third and fourth flange elements; and wherein in an assembled condition, the rear panel extends upwardly above the opposite side panels at an obtuse angle to the grate, and wherein a forward portion of the apparatus is open so that flames can be directed substantially vertically and radiant heat directed 5 forwardly.

[0041] The present invention has numerous benefits including the following, which represents an advance over prior art: • Efficient for transporting as the assembly comes in a substantially flat pack of io         interconnecting components; • Easy to assembly substantially in the absence of hinges or threaded fastenings, and enabling quick assembly and disassembly • Lightweight and easy to carry in an assembled condition; • Efficient flame and heating even if raining; 15      • Substantially reduced smoke generating; • Radiant heat down low, deters mosquitos; • Residual ash is contained and easy to dispose.

[0043] It should be noted in the following description that like or the same reference numerals in different embodiments denote the same or similar features.

[0044] Referring to figures 1 to 9 a preferred embodiment of the system and apparatus 30 for forming a portable camp fire 1 for camping and recreational use is shown having two substantially planar L-shaped panels 3a and 3b forming spaced side walls; a back panel 4 being a relatively high back compared to at least a front part of the two substantially planar L-shaped panels, and a base panel 2 having a trapezoidal planar plate portion 23 and incorporating an integral front upturned portion 24. 2025201594   05 Mar 2025

[0045] The base panel 2 and back panel 4 are detachably mounted by forward and rearward portions respectively of the side walls 3a and 3b, with the base plate 23 suspended close to but above the ground and a forward facing open end. As best shown in figure 1, the combination of high back panel, low front upturned portion 24 of 5 the base panel, and side walls combine to form a surround for receiving fuel in the form of wood pieces and retaining coals, while directing radiant heat towards the open front end of the assembly.

[0046] As shown, the back panel 4 and the base plate 23 form an L-shaped structure io with open front retaining structure forming the portable camp fire. The back panel includes a relatively high back compared to a front portion of the side walls which extends the fire in a vertical direction to form a vertical fire. The low front upturned portion 24 of the base panel 2 provides a partial open front or forward end and a retaining structure with the side walls 3a and 3b and back panel 4. The back panel 4 15 further includes an intermediate lateral step 20 and spaced vertical oriented ventilation openings 21 and 22 on either side of the step 20 to allow location of wood pieces upright against the back panel and create air gaps for promoting a vertical fire and minimising smoke. 20

[0047] The front upturned portion 24 of the base panel 2 inter-fits with the two substantially planar L-shaped panels 3a and 3b at forward locations, and the back panel 4 similarly interfits with panels 3a and 3b at rearward locations. As shown, the base panel 2 includes a planar portion 23 and a forward upturned edge portion 24 forming a coal retaining area and providing an open frontal area for horizontal 25 funnelling of radiant heat. The base 2 includes a series of perforations in the planar plate 23, and the plate 23 is supported off the ground. The assembly formed by the side walls, back panel and base panel provides a fire above ground forming a coal and wood retaining area and providing an open frontal area for horizontal funnelling of radiant heat. 30

[0048] In an assembled condition the back panel 4 and the planar plate 23 of the base panel 2 are located at an obtuse angle relative to each other. The two substantially planar L-shaped panels include a series of slotted openings 25 adjacent to the planar base portion 23 of the base panel 2 to allow air ingress at or close to the floor of the 2025201594   05 Mar 2025 base plate 23. Referring to figures 1 and 2, in an assembled condition the axis of the back panel 4 is located at an obtuse angle to the base plate 23, and the back panel 4 and side walls 3a and 3b include inter-engaging means which allow assembly and disassembly. 5

[0049] In the embodiment shown in in figure 1 the inter-engaging means include: split arrow head shaped slotted recesses 6 in the high rear portion and the stepped down portion towards the front end thereof of the two substantially planar L-shaped side wall panels, and ‘T’ and ‘C’ - shaped lugs 5 incorporated in and projecting laterally from io opposite sides of the front upturned portion 24 of the base 2 and back panel.

[0050] In assembling the panels, the lugs 5 slide into the split arrow head shaped slots 6 of the side panels, drop downwards and wherein the back panel is then rotated about 30 degrees towards the rear to secure the assembly in place. The lugs 5 extending 15 from the front upturned portion 24 are similarly then inserted into oppositely disposed forward slots 6 on the side walls and rotated rearwards to complete the engagement. The back panel includes a bottom flange 30, which receives an end rear section 140 of the base plate 23 thereon in a seated condition. 20

[0051] Disassembly of the unit is achieved by rotating the back panel forwards. The obtuse angular positioning of the axis of the back panel with respect to the planar base plate 23 allows this forward rotation to cause sliding disengagement of the base plate from a seated condition on the bottom flange of the back panel. \ 25

[0052] The C- shaped lugs 5 on opposite sides of the front upturned portion 24 of the base panel 2 being received in split arrow head slotted recesses in stepped down forward end portions of the side panels 3a and 3b.The two substantially planar L-shaped panels 3a and 3b which form side walls of the assembly include a high rear portion 26 adjacent the back panel, and a stepped down lower portion 27 towards the 30 front end thereof to provide an open frontal end with the front upturned portion 24 of the base panel 2. As shown, the base plate 23 is trapezoidal being narrower at the rear and progressively widening towards the front end of the assembly. 2025201594   05 Mar 2025

[0053] This structural feature assists in stabilising the structure and to provide a narrow semi confined vertical series of hot flames. The structure formed by the assembly encourages radiant heat to be directed more outwards at ground level in an arc of approximately 90 degrees. This is more efficient in warming people’s knees and feet 5 because heat is directed lower down to the ground. The two substantially planar L-shaped side wall panels further include arcuate slots 29 in the high rear portions to allow insertion of hands for manoeuvrability of the assembly whilst cold.

[0054] Referring to figures 2, 3 and 9, the assembly further includes a holding tray 28 io located on the ground underneath the base panel 2. When the fire is extinguished, the back panel can be rotated forwards to disengage its lower flange from its supporting function of base 23. Upon removing the back panel and clasping the hand hold slots 29 any residual ash and coals on the base can be shaken downwards into the holding tray 28 for easy disposal of fire residue. 15

[0055] If the fire is in operation without employing a base tray 28, and therefore the unit is hot, two people may carefully move it to another location by lifting the assembly together, via the arcuate side wall slots with the hooked ends of the steel bars 31. If in operation with a base tray, the assembly may be maneuvered about by simply hooking 20 the tray’s edge with long tongs or the hooked end of a long tent peg or the like.

[0056] Turning to figure 9 there is further shown an assembly 1 received within a holding tray 28 which is at least partially filled with water. In accordance with the invention the side walls 3a and 3b of the assembly further comprise a series of spaced 25 apart recesses 41 in lower portion 27 and / or upper portion 26 forming opposite pairs of recesses for receiving cross members 50 to support a tray or other vessel over the coals or fire. In figure 9 there is shown a hot plate 60 stably received on top edge portions of the side walls and resting against the rear wall 4. 30

[0057] As shown in figures 5 and 6, the panels lay substantially flat onto the holding tray for space savings and to allow easy pack-up by sliding into a carry bag 30. The resulting kit forms a thin (70mm) flat pack in a carry bag, which takes up minimal space. Such as kit assembly as shown weighs less than 5Kg and disassembles into a 2025201594   05 Mar 2025 flat pack for convenient carrying in the carry bag. This makes the assembly safe to handle, pack and transport.

[0058] The panels are made from Stainless Steel using laser cutting, although could 5 be fabricated from mild steel. However thicker and thus heavier material would be needed because Mild steel softens appreciably more when heated. Furthermore mild steel rusts badly after being heated and left overnight in the relatively moist air. ASSEMBLY io

[0059] Referring to Figs 1,7-8, during assembly each side panel is held upright whilst the back panel lugs are slid into the slots and grounded down to the base of each slot whereupon the back panel can be rotated about 30 degrees towards the rear to secure the rear portion of the assembly in place. The front / base panel is then slotted into the side walls and in a similar manner enabling it to also be rotated about 30 degrees 15 towards the rear, until narrow end of the base comes to rest on the back plate’s lower flange. DISASSEMBLY

[0060] The obtuse angular positioning of the back panel with respect to the base allows 20 forward rotation then lifting sufficiently to cause sliding disengagement of the base plate from its seated condition on the bottom flange of the back panel enabling detachment of the rear panel. Similarly, complete disassembly can be achieved by rotating the upturned front panel of the base forwards and lifting to finally release the two side panels. 25

[0061] Referring to figures 10 to 15, there is shown a further embodiment in accordance with the present invention. As shown, the apparatus comprises an assembly having multiple substantially planar panels including a rear panel 70, two oppositely disposed side panels 71 and 72, a base panel 73, with no holes or 30 openings, and a grate 74. Each panel has releasable engaging structures so that the panels may be interconnected for assembly of the apparatus and disengaged for efficient transport in a substantially flat condition. 2025201594   05 Mar 2025

[0062] The side panels 71 and 72 include an L-shaped forward cut-out portion 115 forming an open front side portion B, and a series of spaced openings 112 therealong which progressively reduce in size from rear to front. The side panels and rear panel form a partial enclosure to allow control of flame direction in a substantially vertical 5 direction at a rearward end C, and the at least forward open end assists to control directional flow of radiant heat from a fire. The side panels also include ground engaging feet 90 and 91.

[0063] The side panels 71 and 72 include two pairs of oppositely disposed slotted io openings, a first pair 81 and 82 located at a forward location (A) and the second pair 83 and 84 being located at a rearward location (C) of the apparatus. In this embodiment, the opposite pair of slotted openings at the forward location of the side panels interconnect with mating structures on the base panel 73, and the opposite pair of slotted openings at the rearward location of the side panels interconnect with mating 15 structures on the rear panel 70.

[0064] The each pair of slotted openings comprise an arrow head or barbed cut-out configuration; the first pair 81 and 82 of slotted openings located at opposed forward ends of the side panels and the second pair 83 and 84 of slotted openings located at 20 opposite rearward end of the side panels.

[0065] The rear panel 70 includes a first pair of oppositely disposed laterally extending flange or tab-like structures 85 and 86.

The slotted openings 83 and 84 are configured to allow insertion of the flange structures in a first condition and engagement by rotation in a first direction after insertion. Disengagement follows opposite rotation and disassembly by withdrawal of the flange 30 from the slotted opening.

[0066] The rear panel includes a stepped portion 75 intermediate a lower portion 76 and an upper portion 77. The lower and upper portions of the rear panel comprise a series of vertically oriented openings 92 and 93 respectively and at least some of the 2025201594   05 Mar 2025 openings 92 in the lower portion 76 include a lateral opening 94. In the embodiment shown in figure 15, there are three spaced apart lateral openings 94. In an assembled condition, the rear panel is angled beyond the perpendicular relative to the base and the stepped portion 75 spaces longitudinal pieces of fire wood from the openings 92 5 and 93 to maintain airflow.

[0067] In this embodiment, the spaced apart lateral openings 94 interconnect with mating structures on the grate 74. As shown, the grate includes a series of flange elements 95 extending from a rearward location thereof, wherein the flange elements io 95 are adapted to be received by the lateral openings 94 in the lower portion 76 of the rear panel 70 in an assembled condition. In an assembled condition, the flange elements are seated on shoulder portions formed by the lateral openings and extend through the lateral openings 94 protruding beyond the rear panel. As shown in figure 15, a central flange element 95 of the grate 74 includes an opening to receive a locking 15 pin 96 and thereby releasably secure the grate to the rear panel.

[0068] The rear panel further includes a seat 97 extending across the rear panel and below the vertical openings in the lower portion of the rear panel. The seat 97 is formed by folding a lower portion inwardly at about 90 degrees to the plane of the rear 20 panel about a fold line 107. In an assembled condition, the seat 97 slidably receives a rear portion of the base panel 73 thereon.

[0069] The base panel 73 and seat 97 include releasable interconnecting structures. In one embodiment (see figure 15 and 17) the base panel includes a tab structure 25 extending downwardly from the plane of the base panel at a location adjacent the rearward end thereof, and the seat includes an opening 108 therein to receive the tab therethrough. The tab further includes an opening therein to receive a locking pin or ring clip or lynch pin 98 to releasably secure the base panel and rear panel. In this embodiment, any accidental disengagement of panels is mininised when an excessive 30 downwards directed pressure is applied to the apparatus.

[0070] As shown in figure 14, the side panels 71 and 72 include slotted openings 81 and 82 symmetrically disposed at a forward location (A) thereof. In this embodiment, the opposite pair of slotted openings interconnect with mating structures on the base 2025201594   05 Mar 2025 panel 73. The mating structures on the base panel 73 includes a first pair of laterally extending flange or tab-like structures 100 and 101 adapted to be received by the slotted openings 81 and 82 in the opposite side panels. As shown in figures 14 and 23, the flange structures 100 and 101 are releasably inserted in slotted openings 81 5 and 82 in a first orientation and the base panel rotated for engagement of respective flange structures 100 and 101 within the pair of slotted openings 81 and 82 in a second orientation. The slotted openings 81 and 82 are configured to allow insertion of the flange structures 100 and 101 in a first orientation and engagement by rotation in a rearward direction after insertion. Disengagement follows opposite rotation and io disassembly by withdrawal of the flange from the slotted opening.

[0071] The base panel further includes a forward upturned front plate 102 extending from a planar portion of the base panel, ending in a pair of spaced apart flange elements 103 and 104. The pair of flange elements 103 and 104 interconnect with 15 spaced apart slotted openings 109 and 110 in a forward portion of the grate 74 by passing therethrough. The flange elements 103 and 104 extend through the forward opening(s) in the grate and rise above the plane of the grate. In this condition, the flange elements sitting proud of the grate can act as propping points for semi-vertical placement of wood in a fire. The apparatus can further include a holding tray 111. The 20 holding tray can be adapted to receive a volume of water therein, which provides an effective insulation means between the apparatus and a supporting surface.

[0072] In an assembled form, the apparatus assumes a chair-like configuration with an open forward end A and side arms B forming partial open front side, and closed 25 rear end C. The apparatus as shown includes a shaped grate 74 mountable by the rear panel 70 and base panel 73. The grate is a substantially planar structure and includes a series of holes and / or slotted openings 80 and is mounted spaced from and above the base panel 73. In this embodiment, a fire is supported above the base panel to allow fine ash to fall through the slotted openings 80 therein. An advantage of 30 having a grate is that openings 111 on the opposing side panels can be maintained during a fire substantially free from build-up of ash and coals that otherwise could stifle sufficient air flow to sustain the fire. 2025201594   05 Mar 2025
