Kind Code:
A
Abstract:
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
