The width of the slits 310 and 410 of the side plates 300 and 400 is slightly larger than the thickness of the side plates 300 and 400 so that the side plates 300 and 400 can enter the slits 410 and 310, respectively, as will be described later. It has become. The gaps or gaps between the protrusions 312 and 412 are also slightly wider than the thickness of the side plates 300 and 400, and as will be described later, the side plate corners 410T and 310T on the tip opening side of the slits 410 and 310 are protrusions. It is designed so that it can be inserted into 312 and 412, respectively.

Next, as shown in FIG. 2D, the bottom plate 500 has a flat plate shape as a whole, and has a shape in which an enclosure 504 is provided around a flat bottom surface 502. The bottom plate 500 is for preventing the fire of the bonfire 100 from directly hitting the ground and for receiving the burnt residue of the bonfire.

Next, the procedure for assembling the bonfire of this embodiment will be described with reference to FIG. First, as shown in FIG. 3A, the opening of the slit 310 of the side plate 300 and the opening of the slit 410 of the side plate 400 face each other, and then one of the side plates 300 and 400 is rotated to the other. Cross each other and push them toward the back of the slits 310 and 410. As a result, the side plate 300 enters the slit 410 of the other side plate 400, and the side plate 400 enters the slit 310 of the other side plate 300. Then, the side plate corner portion 310T on the slit 310 side enters the protrusion 412 of the side plate 400, and the side plate corner portion 410T on the slit 410 side enters the protrusion 312 of the side plate 300. As a result, the side plate corner portions 410T and 310T on the slit tip opening side are sandwiched by the protrusions 312 and 412, respectively.

As described above, the side plates 300 and 400 are crossed and pushed into the slits 310 and 410, and the side plate corner portions 310T and 410T are sandwiched between the protrusions 421 and 312, so that the side plates 300 are as shown in FIG. 3 (B). , 400 are well crossed and joined, the installation legs 308, 408 are grounded, and the side plates 300, 400 become self-supporting. Further, a combustion space 600 for burning fuel is formed in the upper part of the intersection of the intersecting side plates 300 and 400.

Next, the top plate 200 is attached to the upper side of the combustion space 600 of the side plates 300 and 400 as shown by the chain line arrow in FIG. 2 (B). That is, the claws 304 of the side plate 300 and the claws 404 of the side plate 400 enter into the notch 204 of the top plate 200, and the top plate 200 is attached to the side plates 300 and 400 so as to cover the combustion space 600. As a result, the upper opening side of the side plates 300 and 400 is closed and fixed by the top plate 200. After that, the entire assembled top plate 200, side plates 300, and 400 are placed on the bottom plate 500. In this way, as shown in FIG. 3C, the assembly of the bonfire 100 is completed.

When performing a bonfire, fuel such as firewood, charcoal, and pellets is put into the combustion space 600 under the top plate 200, and the fuel is ignited and burned. The fuel may be added before the top plate 200 is attached. At the time of combustion, air is sent to the combustion space 600 from the vertical opening 306 of the side plate 300, the vertical opening 406 of the side plate 400, and the triangular opening on the side surface of the space. At this time, cooking utensils such as a pot can be placed on the top plate 200, or the ingredients can be placed directly on the grate 208 for cooking.

In this case, since the top plate 200 and the side plates 300 and 400 are made of a metal such as stainless steel, they expand due to heat. Also, if combustion is stopped, shrinkage will occur. However, according to this embodiment, since the side plate corner portions 310T and 410T on the slit tip side of the side plates 300 and 400 are sandwiched and pressed by the protrusions 421 and 312, the misalignment between the side plate 300 and the bottom plate 500 may occur. Distortion can be suppressed well. As described above, according to the present embodiment, the structure is simple and the assembly is easy, but the deformation is satisfactorily reduced even if thermal expansion / contraction occurs.

<Other Examples> The present invention is not limited to the above-mentioned examples, and various modifications can be made without departing from the gist of the present invention. For example, the following are also included.
(1) The shape and dimensions in the above-mentioned embodiment are examples, and can be changed so as to perform the same function. For example, FIG. 4 shows a bonfire 101, which is a miniaturized version of the bonfire 100 of the embodiment, and is composed of a top plate 201, side plates 301, 401, and a bottom plate 501. Other parts are the same as those in the above embodiment. In addition, the crossing angles of the side plates 300 and 400 and the shape and number of openings for sending air may be appropriately changed.
(2) The locking structure of the notch 204 and the claws 304 and 404 shown in the above embodiment is also an example, and various structures may be used as long as the top plate 200 can be locked to the upper portions of the side plates 300 and 400.
(3) In the above embodiment, the protrusions 312 and 412 are provided only on one surface of the side plates 300 and 400, and the corner portions 310T and 410T of one side plate of the slits 310 and 410 are sandwiched between the protrusions 421 and 312. However, the protrusions 312 and 412 may be provided on both the front and back surfaces of the side plates 300 and 400 so that both the corners of the side plates of the tip openings of the slits 310 and 410 are pressed by the protrusions.
(4) In the above embodiment, the slits 310 and 410 of the side plates 300 and 400 are provided in the horizontal direction, but they may be provided in the axial direction (horizontal direction in FIG. 2) where the side plates 300 and 400 intersect. However, since the bonfire 100 is preferably installed horizontally, in that case, the crossing axis direction is horizontal or substantially horizontal.
(5) The top plate 200 and the bottom plate 500 shown in the above embodiment may be used as needed. For example, when only a bonfire is performed, the top plate 200 is unnecessary.

According to the present invention, slits are provided in each of the side plates so that the side plates intersect each other and are fitted into the slits, and the corners of the side plates at the tips of the slits are sandwiched by protrusions, so that the structure is simple. Therefore, although it is easy to assemble, it can maintain a good state after assembly even if it expands or contracts due to heat, and is suitable as a bonfire.
