Description

Technical Field

[0001] The present invention particularly relates to an assembling-type fire pit and an assembling-type fire pit set that are used for applications such as outdoor cooking and heating.

Background Art

[0002] In recent years, the popularity of camping has risen along with the spread of outdoor activities. While it is common to enjoy campfires at night during camping, from the perspective of environmental conservation and the like, directly building firewood on the ground to make a campfire (so-called open ground fire) is prohibited in many campgrounds. For this reason, fire pits that allow campfires to be made with the fire bed raised off the ground are widely used at campgrounds.

[0003] Among such fire pits, an assembling-type fire pit is known, which forms a fire bed by combining a plurality of plate members, and can be disassembled and stored compactly when not in use. Such assembling-type fire pits are disclosed, for example, in Patent Document 1 and Patent Document 2, and have excellent portability, so they are suitable for cases where users wish to keep their carried items compact, such as people heading to campgrounds by bicycle or motorcycle.

Summary of the Invention

Problems to be Solved by the Invention

[0005] However, conventional collapsible fire pits have a fixed size for the fire bed. Therefore, if a user wants to change the size of the fire bed according to the cooking method or the number of people using it, they would need to prepare multiple fire pits of different sizes or purchase a larger fire pit. In the end, this fails to satisfy the need to keep portable items compact.

[0006] This invention has been made in view of the conventional situation described above. One of the objectives of this invention is to provide an assembly-type fire pit and assembly-type fire pit set that can satisfy the need to make portable items compact while also allowing the size of the fire bed to be changed. Means for solving the problem and effects of the invention

[0007] The first aspect of the present invention relates to an assembly-type fire pit which can be configured to include two first members, each having a substantially rectangular plate material with a first side, a second side opposite to the first side, and a third and fourth side adjacent to the first and second sides, and a plurality of second slits, which are a plurality of slits provided diagonally from the third side toward the first side and a plurality of second slits, which are a plurality of slits provided diagonally from the fourth side toward the first side; and a plurality of second members, each made of a substantially rectangular plate material, which engage with the opposing first slit or the second slit when the two first members are facing each other and are installed between the two first members.

[0008] According to the above configuration, the first and second members, which are plate materials, are engaged through the first and second slits, which are slits, so when disassembled, the members can be stacked and stored compactly.

[0009] Furthermore, because a gap naturally forms between the second components depending on the spacing between the first and second slits, ventilation is improved, resulting in effects such as improved combustion efficiency, easier ignition, and reduced smoke generation in the assembled fire pit.

[0010] Furthermore, for example, combining two collapsible fire pits can create three fire pits, and combining three can create five fire pits. In other words, if you prepare n collapsible fire pits (a natural number greater than or equal to 2), you can use them as n fire pits, or combine them to create up to 2n-1 fire pits.

[0011] This allows for the formation of more fire pits than the number of portable collapsible fire pits, thus satisfying the need for compact portable items while providing a collapsible fire pit with adjustable fire pit size.

[0012] A second aspect of the present invention allows for the assembly of a fire pit to be configured to include multiple grates.

[0013] According to the above configuration, for example, each collapsible fire pit can be equipped with two grates. In this case, if two collapsible fire pits are prepared, four grates can be provided, and the maximum number of fire beds that can be formed is three. If three collapsible fire pits are prepared, six grates can be provided, and the maximum number of fire beds that can be formed is five.

[0014] In other words, by equipping a single modular fire pit with multiple (two or more) grates, it is always possible to have more grates than the maximum number of fire pits that can be formed, and the necessary number of grates for placing firewood, charcoal, solid fuel, etc., is naturally provided within each fire pit. The extra grates can also be used as a grilling net, for example.

[0015] A third aspect of the present invention relates to an assembly-type fire pit in which the first member has a third slit, which is a plurality of slits that engage with the grate so that the grate can be erected between the two first members.

[0016] According to the above configuration, since the grate is engaged via a third slit, the components can be stacked and stored compactly when disassembled. Furthermore, the position of the grate can be adjusted by changing the third slit to which it engages.

[0017] A fourth aspect of the present invention relates to an assembly-type fire pit in which the second member has a fourth slit that engages with the first slit or the second slit in a lap-lock manner.

[0018] According to the above configuration, the first slit or the second slit and the fourth slit can be engaged in a lap-lock manner, so that the advantage of being able to stack the components and store them compactly when disassembled is not lost, assembly can be made easier and the strength during assembly can be improved.

[0019] A fifth aspect of the present invention relates to an assembly-type fire pit set which can be configured to include the assembly-type fire pit and a substantially rectangular parallelepiped-shaped packaging capable of storing all the components constituting the assembly-type fire pit.

[0020] The assembly-type bonfire stand set according to the sixth aspect of the present invention can be configured such that the packaging body has a packaging body having a first bottom surface which is one surface, a first side surface which is four surfaces adjacent to the first bottom surface, and a first opening which is an opening at a position opposite to the first bottom surface; a second top surface which is one surface, a second side surface which is four surfaces adjacent to the second top surface, and a second opening which is an opening at a position opposite to the second top surface, and a lid which can be inserted into the packaging body through the second opening with the first bottom surface and the second top surface facing each other, and an elastic part which is an elastic material; and a fixing part which applies force in a direction that reduces the distance between the first bottom surface and the second top surface, fixing the packaging body and the lid when the members constituting the assembly-type bonfire stand and the elastic part are arranged between the first bottom surface and the second top surface.

[0021] According to the above configuration, the members constituting the portable fire pit are stored in the package in a state of being fixed with an appropriate force by the elastic force of the elastic portion and the pressing force of the fixing portion. This prevents the members constituting the portable fire pit from moving inside the package, and can suppress the generation of noise caused by contact between the package and the members.

[0022] The portable fire pit set according to the seventh aspect of the present invention can be configured such that the long side of the package is less than 34 cm, the short side is less than 25 cm, and the total weight is less than 4 kg.

[0023] According to the above configuration, shipping using Letter Pack Plus (registered trademark), a service provided by Japan Post Co., Ltd., becomes possible, and reduction in transportation costs can be expected. Brief Description of the Drawings

[0026] One embodiment of the present invention, the assembled fire pit set 1, mainly consists of an assembled fire pit 11, a packaging body 12, an elastic part 13, and a fixing part 14. Each component is described below. <Assembly-type fire pit 11>

[0027] As shown in Figures 1 and 2, the modular fire pit 11 consists of two first members 111, six second members 112, and two grates 113. 《First component 111》

[0028] As shown in Figure 3, the first member 111 is a substantially rectangular plate material having a first side 111a, a second side 111b, a third side 111c, and a fourth side 111d.

[0029] Furthermore, the first member 111 has three first slits 111e provided diagonally from the third side 111c toward the first side 111a, and three second slits 111f provided diagonally from the fourth side 111d toward the first side 111a. The first slits 111e and the second slits 111f engage with the fourth slit 112a of the second member 112 in a lap joint manner. As a result, as shown in Figures 1 and 2, the second member 112 can be erected between two first members 111 that are facing each other.

[0030] Furthermore, as shown in Figures 1 to 3, the first member 111 has six third slits 111g that can engage with the protrusions 113a of the grate 113, allowing the grate 113 to be installed between the first members 111. At this time, the position of the grate 113 can be adjusted by changing the third slits 111g that are engaged.

[0031] Furthermore, as shown in Figures 1 to 3, the first member 111 has an opening 111h, which can be used as a handle for the assembled fire pit 11.

[0032] The configuration of the first member 111 is not limited to those described above. For example, the number of the first slit 111e, the second slit 111f, and the third slit 111g can be changed as appropriate. 《Second component 112》

[0033] As shown in Figure 4, the second member 112 is a substantially rectangular plate material that engages with the opposing first slit 111e or second slit 111f, as shown in Figure 1, and is installed between the two first members.

[0034] At this time, a gap is naturally formed between the second members 112 according to the distance between the first slit 111e and the second slit 111f, which improves ventilation and results in effects such as improved combustion efficiency of the assembled fire pit 11, improved ignition, and suppression of smoke generation.

[0035] Furthermore, as shown in Figure 4, the second member 112 has a fourth slit 112a that engages with the first slit 111e or the second slit 111f. Since the fourth slit 112a engages with the first slit 111e or the second slit 111f in a lap-lock manner, assembly can be made easier and the strength during assembly can be improved without compromising the advantage of being able to stack the members and store them compactly when disassembled.

[0036] The configuration of the second member 112 is not limited to those described above. For example, the second member 112 does not necessarily have to have the fourth slit 112a. Rostol 113

[0037] As shown in Figure 5, the grate 113 is a mesh having a protrusion 113a, and can be used to place firewood, charcoal, solid fuel, etc., within the fire pit (the area surrounded by the first member 111 and the second member 112), or as a grilling net.

[0038] Furthermore, as shown in Figures 1, 2, and 5, the grate 113 has a projection 113a that can engage with the third slit 111g of the first member 111, and is configured to be installed between the first members 111. Also, since the first member 111 has six third slits 111g, the position of the grate 113 can be adjusted by changing the third slit 111g that engages with the projection 113a.

[0039] The collapsible fire pit 11 is equipped with two grates 113. In this case, if two collapsible fire pits are prepared, four grates can be provided, and the maximum number of fire beds that can be formed is three. If three collapsible fire pits are prepared, six grates can be provided, and the maximum number of fire beds that can be formed is five (combinations of the collapsible fire pit 11 will be described later).

[0040] In other words, by equipping a single modular fire pit with multiple (two or more) grates, it is always possible to have more grates than the maximum number of fire pits that can be formed, and the necessary number of grates for placing firewood, charcoal, solid fuel, etc., is naturally provided within each fire pit. The extra grates can also be used as a grilling net, for example.

[0041] The configuration of the grate 113 is not limited to those described above. As shown in Figure 6, legs 113b may be provided on the grate 113 to improve the stability of the assembled fire pit 11.

[0042] Furthermore, the number of grates 113 provided in the modular fire pit 11 may be one or three or more. Moreover, the modular fire pit 11 according to the present invention does not necessarily need to be equipped with grates 113, and the user may prepare a separate grate (whether or not it can be erected between the first members 111). 《An example of combining multiple assembly-type fire pits 11》

[0043] The modular fire pit 11 can be combined in multiples to form more fire pits than the number of units combined. Specifically, by preparing multiple modular fire pits 11 with a portion of the second member 112 removed, and bridging the gaps between these multiple modular fire pits 11 with the removed second member 112, new fire pits can be formed between the multiple modular fire pits 11. For example, Figure 7 shows a state in which two modular fire pits 11 are combined to form three fire pits.

[0044] In short, if you prepare n (a natural number greater than or equal to 2) of these modular fire pits 11, you can use them as n fire pits, or you can combine them to create up to 2n-1 fire pits.

[0045] This allows for the formation of more fire pits than the number of portable collapsible fire pits, thus satisfying the need for compact portable items while providing a collapsible fire pit with adjustable fire pit size. Other components of the 11-piece assembly fire pit

[0046] The configuration of the modular fire pit 11 is not particularly limited and can be modified as appropriate. That is, by making it possible to engage members other than those mentioned above with the modular fire pit 11, further functions can be freely applied to the modular fire pit 11. For example, as shown in Figure 8, a third member 114 having a groove for holding skewers may be installed between the first members 111. <Package 12>

[0047] As shown in Figure 9, the packaging body 12 is a component having a packaging body 121 and a lid 122. The packaging body 121 has one first bottom surface 121a, four first side surfaces 121b, and a first opening 121c. The lid 122 has one second top surface 122a, four second side surfaces 122b, and a second opening 122c.

[0048] As shown in Figure 9, the packaging 12 can house all the components that make up the assembly-type fire pit 11, as well as the elastic part 13. Furthermore, as mentioned above, the first component 111, the second component 112, and the grate 113 that make up the assembly-type fire pit 11 are made of plate material, and each component engages with a slit that has no thickness, which allows the assembly-type fire pit 11 to be compactly stored in the packaging 12.

[0049] Furthermore, the packaging 12 can be configured such that the longest side is less than 34 cm and the shortest side is less than 25 cm, and the total weight of the assembled fire pit set 1 is less than 4 kg. This makes it possible to ship the assembled fire pit set 1 using Letter Pack Plus (registered trademark), a service provided by Japan Post Co., Ltd., and is expected to reduce transportation costs.

[0050] The form of the packaging 12 is not limited to those described above and can be changed as appropriate. <Elastic part 13>

[0051] The elastic part 13 is an elastic component, and as shown in Figure 9, it is a component that is stored in the packaging 12 along with all the components that make up the assembled fire pit 11.

[0052] For example, a flame-retardant sheet with a certain thickness can be used as the elastic part 13. <Fixed part 14>

[0053] As shown in Figure 9, the fixing part 14 is a member that fixes the main body 121 and the lid 122 when all the components constituting the assembled fire pit 11 and the elastic part 13 are housed in the packaging 12.

[0054] At this time, the components constituting the collapsible fire pit 11 and the elastic part 13 are positioned between the first bottom surface 121a and the second top surface 122a, and the fixing part 14 applies force in a direction that reduces the distance between the first bottom surface 121a and the second top surface 122a. In other words, the components constituting the collapsible fire pit 11 are stored in the packaging 12 in a state where they are fixed with appropriate force by the elastic force of the elastic part 13 and the pressing force of the fixing part 14.

[0055] This prevents the components of the assembled fire pit 11 from moving within the packaging 12, thereby suppressing the generation of noise caused by contact between the packaging and the components. [Explanation of Symbols]
