  Hereinafter, embodiments of the present invention will be described.

  The material of the assembly chair according to the present invention may be any material that has sufficient strength and can be easily bent and cut, such as corrugated cardboard, cardboard, and resin board. For example, use an empty box of a plastic bottle. You can also.

  In FIG. 1, the perspective view of the assembly chair 1 which concerns on this embodiment is shown. The assembly chair 1 includes a leg portion 2 and a seat portion 3.

  The leg 2 is composed of two rectangular plate-like bodies 21 having the same shape, and FIG. 2 shows a development view of one rectangular plate-like body 21 of the leg 2.

  The rectangular plate-like body 21 is provided with a fold line 213 perpendicular to the long side, and three leg surfaces 211 are formed with an equal width. In addition, the first slit 214 extends from one end of the long side to a position corresponding to the length of half of the short side at right angles to the position where the long side of the rectangular plate-like body of the leg surface 211 is equally divided into two. It is provided one by one.

  At one end of the rectangular plate-like body 21, there is provided a connecting portion 212 having a narrower width than the leg surface 211 and formed by a fold line 213 formed at right angles to the long side and a short side of the rectangular plate-like body 21. On the short side of the rectangular plate-like body 21, second slits 215 are provided at positions corresponding thereto.

  Next, the assembly method of the leg part 2 is demonstrated using FIGS.

  First, as shown in FIG. 5, the rectangular plate-like body 21 is bent along a fold line to form a triangular prism with three leg surfaces 211. Next, as shown in FIG. 6, the rectangular plate-like body 21 is elastically deformed and the second slits 215 provided on the short sides are inserted and locked together so that the triangular prism is not opened. The slit 215 may be linear, but it is preferable that the slit 215 be L-shaped because it is difficult to release the lock. In addition, when making it L-shaped, if the shaft part of one L-shaped second slot 215 and the tip of the other L-shaped second slit 215 are at the same height from the seat surface 31, it is ensured. It can be locked and is more preferable.

  Next, as shown in FIG. 7, the two triangular prisms are inserted into the first slits 214 corresponding to each other and fitted to form a star-shaped hexagonal column, which is the leg 2. FIG. 8 shows a state assembled into a star-shaped hexagonal column. In order to insert the first slits 214 into each other, the width of the first slits 214 needs to be wider than the thickness of the rectangular plate-like body 21, but if it is too wide, play is possible, which is not preferable. Further, if the insertion openings of the first slit 214 and the second slit 215 are chamfered, the insertion becomes easy and the assembly becomes easy.

  Further, when the width of the connecting portion 22 is one third or less of the width of the leg surface 211, when the two triangular prisms are fitted to form a star-shaped hexagonal column, they are inserted without interfering with each other. Can do. On the other hand, when the width of the connecting portion 22 is one-sixth or more of the width of the leg surface 211, the second slit 215 can be made sufficiently long, and the triangular prism can be reliably locked. Therefore, it is preferable that the width of the connection portion 22 is one third or less than one sixth of the width of the leg surface 211.

  Next, the seat part 3 will be described. FIG. 3 shows a development view of the seat portion 3.

  A hexagonal shape which is larger than the star-shaped hexagonal shape of the leg 2 by a width twice the thickness of the rectangular plate-like body 21 is defined as a seating surface 31. Each side of the seat surface 31 is provided with a side surface 311 having an arbitrary height, the first folding line 312 at a position where the seat surface 31 and the side surface 311 are in contact with each other, and the height of the side surface parallel to the seat surface. A second broken line 313 at a half position is provided. Further, every other side surface 311 is provided with ear portions 314 on both sides of the side surface in parallel with the seat surface at a portion outside the seat surface.

  First, as shown in FIG. 6A, the side surface 311 with the ear portion 314 is inward at the second fold line 313 and further folded inward at the first fold line 312. Next, the side surface 311 without the ear part is folded at the second fold line 313 while sandwiching the adjacent ear parts 314, and further folded inward at the first fold line 312 to form a lid shape. Thereafter, as shown in FIG. 10, the inner lid 32 shown in FIG. 4 formed in a hexagonal shape having the same size as the star-shaped hexagonal shape of the leg portion 2 is inserted to suppress the side surface 311. In addition, when the number of the inner lids 32 is plural, the strength of the seat portion 3 can be further increased, which is preferable.

  Finally, as shown in FIG. 11, the seat portion 3 is placed on the leg portion 2 to complete the assembly. FIG. 1 shows the assembled chair 1 in the assembled state.

  In the case of simple use, the seat portion 3 may be simply placed with several cardboard sheets laminated together, or if a seat cushion is provided, it may be placed only. Further, when a large cardboard paper can be used, an assembly chair or a desk having a leg height can be used.

  The assembly chair according to the present invention can be assembled and disassembled easily, and can be stored and transported by disassembling it to reduce its volume, which is suitable as an emergency measure for event venues and disasters. In addition, it can be made using empty boxes such as plastic bottles, and is environmentally friendly.
