To provide blocks to construct various life-size play structures by removing defects of conventional technologies, and a system thereof.
A number of inflatable building blocks with a number of side faces are included. Each block is a cylinder whose section is polyhedral, and the lengths of the sides of the polyhedron are equal. The blocks are arranged in such a way that adjacent sides of each block are aligned with adjacent sides of the adjacent block, and the block is firmly fixed to the adjacent block by joints not to be displaced from each other. The joints are disposed at fixed positions along the sides of the blocks at a specific proportion. The consistency in the size of each block is retained by a reinforcing means, and the uniformity of the system among the blocks is retained. Play structures in various shapes can be constructed by combining the blocks.
