した方形状の偏平袋状体Aが形成さればよい。 Reference numerals 9 and 10 are folding margins, and a substantially trapezoidal notch U is provided in the middle of the folding margins 9 and 10. Then, the above-mentioned glue allowances 6, 6a, 7, and 7a are each folded inward and the folded outer surfaces are glued together using, for example, a resin adhesive (product name: Zybinol, etc.), and the folding allowance 9 on the open end side is , 10 are bent inward to form a flat bag-like body A. Note that adhesive allowances (for example, 6 and 7) may be provided only on the left and right sides of the front plate 4 and the rear plate 5 on opposite sides, and the positions of the adhesive allowances (adhesion positions) are on both the left and right sides of the front plate 4 and the rear plate 5. The position is not limited to the illustrated example in which the parts are glued together, and the position can be appropriately selected depending on the cut shape of the plate material. Furthermore, the corrugated board may be single-layered (double-sided corrugated board), and in addition to corrugated board, it is also possible to use board materials that are relatively strong and elastic, such as solid paper, synthetic resin, or tanned leather. You can also glue parts 9 and 10,
In addition to adhesion, wire binding or other appropriate fixing means may also be employed. In short, the rectangular flat bag-like body A with one end open may be formed from a plate material such as solid paper such as cardboard or synthetic resin.
ところで、前面板4と後面板5の内側面(裏側
面)には予めそれぞれ左右巾方向中間部に折れ目
Nが形成されている。 Incidentally, a crease N is previously formed on the inner side surface (back side surface) of the front plate 4 and the rear plate 5 at an intermediate portion in the left-right width direction, respectively.

形成されている。 Similarly, between the left and right upper corner portions C 1 and C 2 there is a substantially arc-shaped fold P mainly consisting of a curve or a straight line, and below the fold P there are both left and right edges of the front plate 4 and the rear plate 5. An M-shaped fold with the points that intersect with the crease P closer to the center in the width direction as the apexes T 1 and T 2 and the bottom points near the left and right lower corners and the intermediate points thereof as the bottom points B 1 , B 2 , and B 3 Eye Q (Fold line Q is symmetrical about crease N)
However, downwardly inclined folds S (α=75°) are formed from the apexes T 1 and T 2 to the side edges.

い。 In addition, among the above-mentioned folds, the fold P is illustrated as being mainly a straight line in the drawing, but a part thereof may be curved R as shown by the dotted line in FIG. In addition, the above-mentioned folds N, P, Q, S, etc. can be formed by cutting the plate material by appropriate known means such as pressing using a blade die (forming a concave groove of about 45° will make it easier to break) or perforating. It can be easily applied simultaneously or in a separate process. Furthermore, the surface side of the board material a may be colored in a desired manner or printed with letters, patterns, etc. in advance, or if surface treatments such as vinyl coating are applied, not only the waterproof performance will be greatly improved, but also the board material's Rigidity is further improved. Further, folds similar to those described above may be provided not only on the back side but also on the front side. In particular, when applying surface treatment such as vinyl coating or when using a relatively thick board, it is easier to break if the folds are provided on both the front and back sides.

易くなる。 Now, when using the folding chair configured as described above, as shown in FIG. , the flat bag-like body A is deformed into a surface with the fold line 3 and the fold line P as the front plate 4 and the rear plate 5 gradually expand in the front and rear direction around the fold line 3 as the outer contour line. Hollow ears 1 with diamond-shaped cross sections on both left and right sides in plan view on the upper side.
An octagonal buttock seat 12 similar to an ellipse long in the left-right direction is formed. In addition, when pressing the upper edge, if both left and right sides of the bag-like body A are pushed in the approach direction, the legs open in the front-rear direction, making it easier to expand.

れる。 By the way, due to the above-mentioned pressing force, the front plate 4 and the rear plate 5 are pushed apart in the front and back direction at the fold P part, and the buttock seat 12 is opened by the folds Q, N, and S as shown in FIGS. 8 and 9. A leg cylinder portion 13 is formed below, which has a trapezoidal shape that widens toward the end in both side and front views. At this time, the outer circumferential surface of the leg tube part 13 is deformed by the folds N, Q, and S so that both the front and rear sides of the flat bag-like body A are bulged and deformed symmetrically about the folding line 3, and the apexes of the triangle are positioned alternately above and below. A polyhedron mainly consisting of triangles is formed, and the lower end open portion is deformed into a rhombus or square shape, and a chair 14 having a horizontally long buttrest seat 12 on the upper surface is formed.

して充分な剛性を得ることができる。 When this chair 14 is under no load and no one is sitting on it, as shown in FIGS. 8 and 9, the fold line 3 at the center of the buttrest seat 12 rises slightly upward due to the elastic return action of the cardboard. However, when a person sits down, a force F 1 is applied to the buttock seat 12, causing the vertical folding line 3 to further displace downward and the buttock seat 12 to become even more flat. A force F 2 is applied in the direction of moving back and forth at the crease P position. Therefore, the front plate 4
The rear plate 5 is gradually expanded and displaced in the front-rear direction. Further, the downward displacement of the folding line 3 and the butt receiving seat 12
Due to the flattening of the hollow ear portion 11 having a diamond-shaped cross section, it gradually collapses and becomes flattened, so that an inward force F3 is generated on the side surface 13a of the leg cylinder portion below the ear portion 11, and as a result, it initially tilts upward. shaped ears 11
gradually transforms into a horizontal or slightly downward sloping shape.
This means that the load applied to the butt support seat 12 is distributed in multiple directions, and therefore, the weight (load) is not directly transmitted to the leg tube portion 13 as a downward pressing force, resulting in improved strength. This is extremely reasonable. In addition, the leg tube portion 13 is not simply cylindrical or rectangular, but is formed into a polyhedron (octahedron) mainly consisting of triangles, so it has strong strength against vertical compression and twisting, and even though it is made of corrugated cardboard, it is made of double-sided corrugated cardboard. Combined with the fact that it is used, it is possible to obtain sufficient rigidity as a chair.

に高めることができる。 In addition, at the adhesive part between the front plate 4 and the rear plate 5, the lower end open part, and the folded part, the cut ends of the cardboard (core 1b, liners 1a, 2, etc.) are not exposed to the outside but are hidden inside, so water resistance is improved. Not only is it good, but the appearance can also be maintained well. In the former case, the inner folded piece acts as a reinforcing rib in the vertical direction, and in the latter case, the folded piece prevents the cut end of the board from directly touching the ground, so the cut end will not collapse or be pushed and bent, and it will remain in contact with the ground. is extremely stable. Furthermore, the leg tube portion 13
The maximum protruding part in the front-rear direction is located at the middle part in the left-right width direction, and the outer surface of the leg tube is tilted backward from this part, so that when sitting, the leg tube part 1
3, the freedom of the feet is maintained well without getting in the way, and the softness and warmth unique to cardboard and the appropriate cushioning properties make it comfortable to sit on. It is extremely convenient because it can also be used as a handhold. In addition, the present invention has a simple structure and is lightweight (for example, about 650 g for a flat bag with dimensions of 47 cm x 42 cm), which greatly reduces manufacturing costs.Furthermore, the flat bag A can be stored in a stacked state. Since it can be transported, transportation efficiency can be greatly increased.
