ASSEMBLY TYPE CHAIR MADE OF CARDBOARD

To provide an assembly type chair made of cardboard which has sufficient strength to endure weight of an infant user to an adult user and to be usable for many hours, has high design that does not look like a disposable product, uses a use member from a plate cardboard member with little loss, and does not cause any environmental problem when disposed of by a packing method requiring low transportation costs.SOLUTION: In an assembly type chair made of cardboard, leg members 100, 101, and 102 are radially inserted in a seat surface member 200 and a bottom member 300 by turns without a gap, so that weight in the vertical direction is supported by numerous leg members and great deformation when seated and leaving the seat is prevented. For the leg members 100 and 101 and the leg member 102 to cross and overlap toward a center on a seat surface, inner sides are in an uneven shape, so that great strength is realized because they can be arranged radially and tightly and no gap appears in the longitudinal direction.SELECTED DRAWING: Figure 6 【課題】幼児～成人の荷重に耐えられ、長期間使える強度と、使い捨てに見えない高い意匠性と、板ダンボール部材からロス少なく使用部材を取り、輸送コストの少ない梱包方法で、廃棄等の際に環境問題を生じさせない段ボール製組立式椅子を提供すること。【解決手段】段ボール製組立式椅子において、放射状に隙間なく脚部材１００および１０１および１０２を交互に座面部材２００と底部材３００に差込むことで、多数の脚部材で上下方向の荷重を支えつつ、さらに着座、退座のときにも大きく変形しないようにした。また脚部材１００および１０１と脚部材１０２は座面中心に向かって交差し重なり合わせるため内側の辺が凹凸形になっており、放射状に密に配置できると同時に、縦方向の隙間がなくなるため高い強度を実現している。【選択図】図６
