Description

Prefabricated Block Toys Set

Toys, which are made of small blocks made of plastic and made to create a desired three-dimensional shape, are called block toys. A block toy is composed of a plurality of blocks in a set form.

Although prefabricated block toys with a coupling structure for fitting protrusions and grooves formed in each block to each other are commercially available, block toys must be fitted with force by matching the protrusions and grooves of each block one by one. It is not easy to disassemble each block to make a three-dimensional shape.

On the other hand, block toys with magnets are available on the market, which allow magnets to be easily joined between blocks by simply placing magnets inside each block. Although the blocks can be conveniently joined together and easily disassembled after assembling, the edges of the blocks are rounded so that the joints between each blocks are not firm, so that the shape is collapsed even after a slight impact after assembling in a three-dimensional shape. There are disadvantages.
