DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A folding stove according to an embodiment of the present invention will be described in detail with reference to the drawings.

As shown in the vertical side views of FIGS. 1 and 2 and the plan view of FIG. 3, a folding stove according to an embodiment of the present invention is formed by bending a round bar member into a square shape in plan view. Shaft frame 1 and opposite sides 1a and 1b of the shaft frame 1 in the front-rear direction
Front and rear side plates 2 whose upper edges are rotatably supported, and a bottom plate 3 whose front and rear side edges are hingedly connected to the lower edges of these front and rear side plates 2 via shafts 7 made of round bars. It has and.

As shown in FIGS. 2 and 3, the lateral width of the front and rear side plates 2 is the distance L between the left and right opposite sides 1c and 1d of the shaft frame 1.
2 x shorter than that, and as shown by the phantom line in the side view of FIG. 4, the distance α between the upper and lower edges of the front and rear side plates 2 is greater than the distance W between the opposite sides 1a and 1b of the shaft frame 1 in the front-rear direction. Is also shortened.

As shown in FIGS. 2 and 3, the left and right widths of the bottom plate 3 are the same as the left and right widths of the front and rear side plates 2. As shown in the side view of FIG. 2 times the interval α between the upper and lower edges of the shaft frame 1 to the opposite side 1a in the front-back direction of the shaft frame 1.
-The length W is set to be 1b.

As a result, as shown by the phantom line in FIG. 4 and the solid line in the side view of FIG. 5 and the plan view of FIG. 6, the front and rear side plates 2 are placed in a space surrounded by the shaft frame 1 in a plan view when not in use. The bottom plate 3 and the bottom plate 3 can be folded in a zigzag shape.

As shown in FIG. 2, a pair of opposite sides 1c and 1d in the left-right direction of the shaft frame 1 include left and right side plates 4 which cover the left and right end faces of the firebox surrounded by the front and rear side plates 2 and the bottom plate 3. The upper edge is rotatably connected.

The front and rear widths of the left and right side plates 4 are slightly larger than the distance between the front and rear opposite sides 1a and 1b of the shaft frame 1, and the height is 1/2 the distance between the left and right opposite sides 1c and 1d of the shaft frame 1. Is also formed into a small inverted trapezoid. Further, in order to maintain the plate shape of each of the left and right side plates 4, a reinforcing rib whose lower edge and front and rear side edges are bent outward is provided, and an upper edge portion is widened rightward or leftward. It is bent over x. Then, by wrapping, for example, the tip end portion of the upper edge portion, that is, the right outer end portion or the left outer end portion around the opposite side 1c · 1d of the shaft frame 1, it is rotatably supported on the opposite side 1c · 1d of the shaft frame 1. I am allowed.

Also, as shown in FIG. 1, the left and right side plates 4 each have, for example, a U-shaped leg 5 whose lower side is opened in a side view.
It is fixed with four bolts 8, and the lower edges of the left and right side plates 4 are
Fixing means 6 for fixing the respective lower edges to the left and right ends of the bottom plate 3 is provided.

In use, as shown in FIGS. 1 to 3, by opening the four side plates 2 and 4 and fixing the lower ends of the left and right side plates 4 to the left and right ends of the bottom plate 3 by the fixing means 6, A trapezoidal gutter-shaped fire chamber is formed between the side plates 2, the bottom plate 3 and both end plates 4, and fuel such as a burner and portable fuel is put into the fire chamber and burned.

The grill on which the food is placed may be placed on the upper side of the folding stove, or may be supported by the bottom plate 3, the left and right side plates 2, the front and rear side plates 4, or the four side plates 2.4. You can do it.

When not in use, the fixing action of the fixing means 6 is released and the side plates 2 and 4 and the bottom plate are folded, but the folding procedure is not particularly limited. For example, first, the left or right side plate 4 and legs are rotated by 90 ° and laid on the ground, and the connecting portion between one of the front and rear side plates 2 and the bottom plate 3 is lifted to form the front and rear side plates 2 and the bottom plate 3 in a zigzag shape. After folding, fold it over the left or right side plate 4 and fold it back onto the shaft frame 1, front and rear side plates 2 and bottom plate 3, and then turn the remaining right or left side plate 4 180 ° while turning it inside out. Then, the front and rear side plates 2 and the bottom plate 3 are superposed on each other to make a thin and compact four-sided side plate 2.4, bottom plate 3, and both legs 5.
Is folded.

Here, the left and right widths of the front and rear side plates 2 are formed to be smaller than the left and right width of the shaft frame 1, and the distance between the upper and lower edges thereof is formed to be shorter than the front and rear length of the shaft frame 1. Therefore, the front and rear side plates 2 can be folded into the plane shape of the shaft frame 1. The left and right widths of the bottom plate 3 are the same as the left and right widths of the front and rear side plates 2, and the front and rear width β is twice the distance α between the upper and lower edges of the front and rear side plates 2 to the opposite side of the shaft frame 1 in the front and rear direction. Since the length is obtained by subtracting the distance W between 1a and 1b,
The bottom plate 3 overlaps the front and rear side plates 2 and is folded in the plane shape of the shaft frame 1. Further, the front-back width is slightly larger than the distance between the front and rear opposite sides 1a and 1b of the shaft frame 1, and the height is smaller than half the space between the left and right opposite sides 1c and 1d of the shaft frame 1. Since it is done, each shaft frame 1
Will be folded into the plane shape of As a result, when the side plates 2 and 4 and the bottom plate 3 are folded, the shaft frame 1 hardly protrudes in a plan view, and portability can be improved.

The front and rear side plates 2 are most preferably formed in a flat plate shape in order to thinly fold the folding stove, but here, in order to maintain the plate shape, an appropriate space is provided in the left and right direction. The reinforcement portion 9 is provided.

The reinforcing portion 9 is formed by a convex strip or a concave strip extending vertically along the plate surface of the side plate 2 by mountain-folding or valley-folding the middle portion of the side plate 2 in the left-right direction by pressing or the like. However, in this embodiment, in order to reduce the cost of the press die, the left and right side edges of the side plate 2 are formed by ribs that are folded back upward.

Further, the bottom plate 3 is most preferably formed in a flat plate shape in order to thinly fold the folding stove, but in this embodiment, an appropriate space is provided in the left-right direction to maintain the plate shape. A reinforcing portion 10 is provided for holding.

The reinforcing portion 10 may be formed by a convex strip or a concave strip that extends in the front-rear direction along the plate surface of the bottom plate 3 by mountain-folding or valley-folding the intermediate portion of the bottom plate 3 in the left-right direction by pressing or the like. However, in this embodiment, in order to reduce the cost of the press die, the left and right side edges of the bottom plate 3 are formed by ribs that are folded back in the vertical direction.

As described above, when the reinforcing ribs 9 and 10 are provided on the left and right ends of the side plate 2 and the bottom plate 3, respectively, when the side plates 2 and the bottom plate 3 are folded, as shown in the side view of FIG. As shown by an imaginary line in the figure, one of the ribs hits the side plate 2 or the bottom plate 3, and the height of the folded side plate 2 and bottom plate 3 becomes higher than the total height of the respective plate thicknesses.

Therefore, in this embodiment, the upper edge portions of the side plates 2 are bent inward at a substantially right angle, and the upper edge portions of the end plates 4 are bent outward at a substantially right angle so that the side plates at the time of folding are folded. 2 and the bottom plate 3 are arranged so as to fit well.

In the above embodiment, the side plates 2 and 4 and the bottom plate 3 are provided.
Reinforcing parts 9 and 10, reinforcing ribs, etc. are provided, and the upper edges of the side plates 2 and 4 are bent into an L shape, but the reinforcing parts 9 and 10 are not provided, and the side plates 2 are not provided. -The upper edge of 4 is not bent into an L-shape, and as described above, the bottom plate 3
When the front and rear width β is set to a length (β = 2α-W) obtained by subtracting the distance W between the opposite sides 1a and 1b in the front and rear direction of the shaft frame 1 from twice the distance α between the upper and lower edges of the front and rear side plates 2. 7, both side plates 2 and the bottom plate 3 can be overlapped so as to make surface contact with each other, and the total thickness of the overlapped plates can be calculated by comparing the thicknesses of the two side plates 2 and the bottom plate 3 with each other. It can be made approximately equal to the total plate thickness including the plate thickness.

In the actual processing technique, when the side plates 2 and 4 are burred to be wound around the shaft frame 1, the outer diameter thereof is four times or more the wall thickness of the side plates 2 and 4, so the thickness of the bottom plate 3 is If it is the same as that of the side plates 2 and 4, even if the front and rear side plates 2 and the bottom plate 3 are overlapped with each other in the space surrounded by the shaft frame 1, the side plate 2
・ 4 can be piled up thinner than the part wound around the shaft frame 1.

Therefore, even if the left and right end plates 4 and the legs 5 are further folded on this, the overall thickness is much thinner than the conventional example, and it can be folded thinly and compactly.
Further, in the above-described embodiment, the fixing means 6 is supported on the inner side surface of each end wall 4 so as to be able to move up and down, and the key 12 is inserted into and removed from the locking holes 11 formed at the left and right ends of the bottom wall 2, and the key 12.

It is free to set up. As the reinforcing portions 25 and 35, in order to prevent ash and the like from remaining during cleaning, the intermediate portion of the side plate 2 or the bottom plate 3 in the front-rear direction is mountain-folded or valley-folded by a press or the like to form the side plate 2 or The bottom plate 3 is formed of a convex strip or a concave strip formed to extend in the left-right direction along the plate surface.

In the above embodiment, the side plate 2
Each of the four is made of a single plate, but as shown in FIG. 9, for example, a folded back parallel to the sides 1a and 1b of the shaft frame 1 to which the side plate 2 is connected between the upper edge and the lower edge thereof. It may be configured by a plurality of plates 221 and 222 that are connected by a line 21 so as to be folded back. However, in this case, in order to enhance portability, it is preferable that each side plate 2 is formed into a shape that can be accommodated within the planar shape of the shaft frame 1 in a folded state.

The side plate 2 is shown in FIG.
It is opened as shown in (a) and is folded together with the bottom plate 3 as shown in (b) or (c) of the drawing when not in use. Further, in the above-described embodiment, the shaft frame 1 is formed in a quadrangle in a plan view, but may be formed in another even-angle polygon such as a hexagon or an octagon in a plan view. It may be formed in an odd-angled polygon such as a triangle or a pentagon.
