Title:
CHAIN BLOCK TOY FACILITATING CONNECTION AND PREVENTING ABRASION BY BEING ELASTICALLY OPERATED VIA LEFT AND RIGHT ROLLING
Document Type and Number:
WIPO Patent Application WO/2017/200186
Kind Code:
A1
Abstract:
The present invention relates to a chain block toy assembled by interconnecting multiple assembly blocks in a fitting manner by using a female coupling part and a male coupling part. In particular, in each of the assembly blocks provided with a plurality of female coupling parts defined by a partition, an open groove is formed in the partition for forming the plurality of female coupling parts such that, when coupling or decoupling a male coupling part or rotating same in a coupled state, vertical supports of the female coupling parts are rolled to the left and right sides, thereby facilitating the coupling and decoupling, while preventing abrasion by minimizing friction.
