[Configuration of leg plate 10]
A pair of leg plates (front and rear leg plates) 10 , 10 each have a substantially circular large hole 11 in the center and legs below the large hole 11 . The shape of the leg portion is not particularly limited, and may be a single plate extending downward from the large hole 11 , a plurality of pieces, or a frame shape of the large hole 11 . As shown in FIGS. 1(A) and 1(B), the legs of this embodiment are composed of two legs 12,12. The large hole 11 of the front leg plate 10 and the large hole 11 of the rear leg plate 10 have the same size and shape and are located at the same position. Also, the leg portions 12, 12 of the front leg plate 10 and the leg portions 12, 12 of the rear leg plate 10 have the same size and shape and are located at the same position. For the leg plate 10, for example, a thin plate material (1 mm in this embodiment) made of lightweight and strong metal (stainless steel, aluminum, etc.) is used. In addition, the leg plate 10 is formed with dimensions that allow it to be carried in an A4 size (210 mm×297 mm) case.

As shown in FIGS. 1(A) and 1(B), in this embodiment, the large hole 11 is not completely circular, but has flat portions on the upper and lower sides, and has small depressions 15, 15 on the left and right inner sides. . The presence of such a recess facilitates engagement of the side plate 20 . Further, although the details will be described later, the upper and lower side plates are assembled around the recesses 15, 15 to form a fire stand of a second assembly example described later. The shape of the large hole 11 is not limited to this, and may have various shapes as long as it is substantially circular, and may be circular. Further, the leg plate 10 has a symmetrical shape in the direction shown in FIG. 1(A).

In this embodiment, one of the pair of leg plates 10, 10 and the other leg plate 10 have different designs and shapes. The entire bonfire is designed with the motif of a traditional pig-shaped vessel for burning mosquito-repellent incense. As shown in FIG. 1(A), the front of the leg plate 10 installed in front is designed to look like the front of a pig, the large hole 11 is the mouth of the pig, and the legs 12, 12 are the legs of the pig. formed by imitation. Eyes and ears are formed above the large hole 11 . As shown in FIG. 1(B), the leg plate 10 installed at the rear is designed to look like the back of a pig, and legs 12, 12 are formed to imitate the legs of a pig, like the front. Ears and a tail are formed above the large hole 11 . By designing the pair of leg plates 10, 10 in this manner, the user will feel attached to the bonfire stand, and there will be an effect of making it enjoyable to use and a healing effect. The pair of leg plates 10, 10 are not limited to the design and shape of this embodiment, and can be formed in various designs and shapes. Also, the front and rear leg plates 10, 10 can have the same design and shape.

First elongated holes 13, 13 extending in the left-right direction are formed in the lower central portions of the large holes 11, 11 of the front and rear leg plates 10, 10, respectively. The first elongated hole 13 is elongated and curved downward. With the leg plate 10 described above and the side plate 20 described later, the bonfire stand 100 having the simplest configuration (first assembly example described later) of the present invention can be configured.

Furthermore, second elongated holes 14, 14 extending in the left-right direction may be drilled in upper central portions of the large holes 11, 11 of the front and rear leg plates 10, 10, respectively. The second long hole 14 is not an essential component of the fire stand 100 of the first assembly example described later, but is an essential component of the fire stand 200 of the second assembly example described later. The second long hole 14 is curved and elongated similarly to the first long hole 13 .

Further, hooking holes 17, 18, 19 and/or hooking grooves 16 may be formed above the large holes 11, 11 of the front and rear leg plates 10, 10. FIG. The hooking holes 17, 18, 19 and the hooking groove 16 are not essential components of the present invention, but by having them, a rod-shaped or plate-shaped trivet can be constructed between the leg plates 10, 10. . In this embodiment, the front leg plate 10 is provided with two hooking holes 18 representing pig's eyes and a pig's ear-shaped hooking hole 17 . In addition, hooking grooves 16 in the shape of pig's ears are formed in the front and rear leg plates 10,10. A hooking hole 19 in the shape of a pig's tail is drilled in the rear leg plate 10 .

The numbers and shapes of the hooking holes and hooking grooves are not limited to those of this embodiment, and can be formed in various shapes. However, in order to install the trivet horizontally as much as possible, it is preferable to form the positions of the hooking holes and hooking grooves of the front and rear leg plates 10, 10 so that they are at approximately the same height. As a result, a pot, a kettle, or the like can be stably placed on the trivet.

In this embodiment, in addition to the large hole 11, the legs 12, 12, and the first elongated hole 13, which are essential components of the leg plate 10, the second elongated hole 14, the hooking holes 17 to 19, and the hooking A leg plate 10 having a stop groove 16 is used.

[Structure of side plate 20]
Next, the configuration of the side plate 20 will be described with reference to FIG. Like the leg plate 10, the side plate 20 is made of a lightweight and strong metal (stainless steel, aluminum, etc.) plate material. As shown in FIGS. 2(B) and 2(C), the side plate 20 is bent into a substantially semicircular shape for use, so a plate material (0.3 mm or less in this embodiment) that is more flexible and thinner than the leg plate 10 is used. .

As shown in FIG. 2A, the side plate 20 is substantially flat and substantially rectangular. The side plate 20, like the leg plate 10, is formed with dimensions that allow it to be carried in an A4 size case. The side plate 20 may be completely flat, or may be slightly curved in advance so that it can be easily curved into a substantially semicircular shape. In this embodiment, the shape of the side plate 20 is substantially rectangular with the left-right direction as the longitudinal direction, but it may be substantially rectangular with the longitudinal direction as the longitudinal direction, or may be substantially square. The side plate 20 has a shape that is bilaterally symmetrical and longitudinally symmetrical in the direction shown in FIG. 2(A). Either side of the side plate 20 may be the front side or the rear side, or either side may be the left side or the right side. A right side portion 204 is used.

A plurality of air holes 23 are formed in the side plate 20 of this embodiment. Although the air holes 23 are not an essential component of the present invention, since the side plate 20 is used as a grate plate, the presence of the air holes 23 for taking in outside air makes it easier to burn fuel such as firewood and twigs. In this embodiment, three air holes 23 extending in the left-right direction are formed in the center of the side plate 20 in the left-right direction. Having the air holes 23 in this way makes it easier to bend the side plate 20 into a substantially semicircular shape. The shape and number of the air holes 23 are not limited to those of this embodiment, and any shape and number may be used.

Engagement grooves 21 are formed at both ends of the front side portion 201 and the rear side portion 202 of the side plate 20 (also at both ends of the left side portion 203 and the right side portion 204). As shown in FIG. 2(A), the engagement grooves 21 are cut in the left-right direction and formed at a total of four locations. The engagement groove 21 is a groove for engaging and fixing inside the large hole 11 when the side plate 20 is curved into a substantially semicircular shape and fitted into the large hole 11 of the leg plate 10 .

Further, recessed holes are formed in the center of the front side portion 201 and the rear side portion 202 of the side plate 20 so that the convex portions 22 are formed respectively. This recessed hole also functions as an air hole. When the side plate 20 is bent into a substantially semicircular shape and fitted into the large hole 11 of the leg plate 10, the projection 22 is fitted into the first long hole 13 or the second long hole 14 of the leg plate 10 and fixed. The side plate 20 described above and the leg plate 10 described above can constitute the bonfire stand 100 having the simplest configuration (first assembly example described later). Also, by using two side plates 20, a fire stand 200 of a second assembly example, which will be described later, can be configured.

Further, a small hole 24 into which a protrusion 32 of the rear plate 30 described later is fitted can be formed in the projection 22 of the side plate 20 . Since the small holes 24 are formed, the back plate 30 can be easily attached to and detached from the bonfire stand. In addition, the position of the small hole 24 is not limited to the top of the convex portion 22, and may be drilled in any position as long as the back plate 30 is attached to the bonfire stand.

Furthermore, a connecting portion can be provided in order to connect the two side plates 20 in the front-rear direction (see FIG. 2(A)) to form a fire stand 400 (a third example of assembly described later). As the connecting portion, for example, in addition to the convex portions 22, 22 of the front side portion 201 and the rear side portion 202 of the side plate 20, small concave portions 25, 25, 26, and 26 are formed on both sides thereof. holes are drilled. This dimpled hole becomes an air hole when not used for connection. The small projections 25 and 26 may have any shape as long as they can overlap and engage with each other.

Further, a long hole 27 extending in the front-rear direction and locking holes 28, 28 may be provided in the vicinity of the left end (left side portion 203) and the right end (right side portion 204) of the side plate 20, respectively. By providing such a long hole 27 and locking holes 28, 28, an auxiliary plate 40, which will be described later, can be installed as a fire grate inside the bonfire. The long hole 27 and locking holes 28, 28 become air holes when the auxiliary plate 40 is not installed.

The side plate 20 used in this embodiment has four engagement grooves 21 and projections 22, which are essential components, as well as a plurality of air holes 23, small holes 24 drilled on the projections 22, It is configured to have small projections 25 and 26 on both sides of the projection 22, a long hole 27 and locking holes 28 and 28. As shown in FIG.

[Structure of Back Plate 30]
A rear plate additionally used in the fire stand of the present invention will be described with reference to FIG. FIG. 3 shows the rear panel 30 of this embodiment. Like the leg plate 10, the back plate 30 is made of a thin plate material (1 mm in this embodiment) made of light and strong metal (stainless steel, aluminum, etc.).

As shown in FIG. 3 , the back plate 30 is formed in a substantially disc shape so as to fit into the large hole 11 of the leg plate 10 . As the back plate 30 of this embodiment, a substantially disc-shaped metal plate obtained by hollowing out the large hole 11 of the leg plate 10 is used. Therefore, the shape of the back plate 30 is substantially the same as the shape of the large hole 11 in which the upper and lower sides are flat (see FIGS. 1A and 1B). By adopting such a shape, the metal plate of the leg plate 10 can be effectively used, and the manufacturing cost can be suppressed. Also, the mounting and demounting of the back plate 30 is facilitated, and the gap functions as an air hole. The outer shape of the back plate 30 of this embodiment is formed vertically and horizontally symmetrically. The outer shape of the back plate 30 is not limited to the present embodiment, and may have various shapes as long as the outer shape fits in the large hole 11 .

A plurality of protrusions 32 are provided on the peripheral edge of the rear plate 30 . The projection 32 is fitted into the small hole 24 of the side plate 20 to fix the back plate 30 to the fire stand. Although the protrusions 32 in this embodiment are provided at two upper and lower positions, the number and positions of the protrusions 32 are not limited to this embodiment, and any number and positions may be provided.

Air holes 31 are formed in the back plate 30 . In this embodiment, an air hole 31 with a spiral design is drilled. By designing the air holes 31 in a spiral shape, a shadow (silhouette) of a fantastic spiral pattern created by the bonfire can be enjoyed. The shape of the air hole 31 is not limited to the shape of this embodiment, and can be various shapes.
