By doing so, the second side plates 5, 6, 7, 8 and the reinforcing plates 11, 12, 13, 14 are laminated between the first side plates 3, 4, and become substantially flat. Thereby, the chair 1 can be accommodated in a relatively small space during transportation or storage. Further, the chair 1 of the present embodiment is in the middle of the above-mentioned assembling process (when the second side plates 5, 6, 7, 8 are folded inward after the reinforcing plates 11, 12, 13, 14 are bonded). Since the chair can be in such a folded state, the chair can be folded into a product. In this case, as shown by the imaginary line in FIG. 6, it is preferable that the first side plates 3 and 4 are temporarily adhered to each other with an adhesive tape v or the like to maintain the folded state.
【００２５】 なお、本実施形態において説明した前記組立方法は、考えられる多くの組立方 法の一つを示すものであり、上述した方法以外にも、例えば、図示しないが、先 ず第２側板５，６，７，８を鋭角に折り曲げると共に、補強板１１，１２，１３ ，１４を水平に折り曲げて、各補強板１１，１２，１３，１４に接着剤を塗布し ておき、天板２の側縁の折目線ａ，ｂを介して着座面Ｘを形成しつつ第１側板３ ，４を互いに対向する方向に折り曲げて、各補強板１１，１３同士及び１２，１ ４同士を接着するようにしてもよい。The assembling method described in the present embodiment shows one of many possible assembling methods. In addition to the above-described method, for example, although not shown, the second side plate is first used. 5, 6, 7, and 8 are bent at an acute angle, and the reinforcing plates 11, 12, 13, and 14 are bent horizontally, and an adhesive is applied to each of the reinforcing plates 11, 12, 13, and 14. The first side plates 3 and 4 are bent in the direction facing each other while forming the seating surface X via the fold lines a and b of the side edges of the reinforcing members 11 and 13 and the reinforcing plates 11 and 13 are bonded to each other.
