Title:
HINGE ELIMINATING THE NECESSITY OF SCREWS, AND ASSEMBLY TOY AND PARTITION USING SAME
Document Type and Number:
WIPO Patent Application WO/2012/053701
Kind Code:
A1
Abstract:
The present invention relates to a hinge to be installed onto a plate-type assembly block, an edge of which has a joint groove and which has stopper protrusions formed at the left and right sides of an inlet of the joint groove so as to narrow the inlet. More particularly, one of the edges of each assembly block is hingedly connected to a corresponding edge of another block so as to be rotatable, and another edge opposite said edge of each assembly block has two fixing pieces to be fixed to the stopper protrusions formed at the joint groove via hooks by means of elastic force. According to the present invention, the assembly blocks may be easily disassembled or assembled by means of elastic force without using screws, and therefore children may easily and safely play with two-dimensional plate-type assembly blocks to construct three-dimensional blocks having a free angle. The assembly blocks of the present invention may also be effectively used in various fields such as partitions for an office, simple partitions for a construction site, and emergency sheds.
