Document Type and Number:
WIPO Patent Application WO/2015/111823
Kind Code:
A1
Abstract:
Disclosed are a toy block coupling structure and a toy block comprising the same. A toy block, according to one embodiment of the present invention, has a structure in which blocks are provided in a block coupling toy so as to be coupled to each other, and comprises: a coupling protrusion; and a coupling hole into which the coupling protrusion is inserted so as to be coupled, wherein the inner surface of the coupling hole comprises a plane portion capable of coming in line-contact with the outer circumferential surface of the coupling protrusion in the depth direction. Therefore, the coupling force between toy blocks can be stably maintained. In addition, the occurrence of defective toy blocks can be reduced and the coupling force between toy blocks can be maintained to be uniform. Furthermore, the coupling of toy blocks can be facilitated.
