BUILDING BLOCK AND BUILDING BLOCK UNIT
Document Type and Number:
WIPO Patent Application WO/2016/015470
Kind Code:
A1
Abstract:
Disclosed is a building block comprising a basic unit (10) and a connecting member (20) connecting two basic units (10). The basic unit (10) is a hexahedron, four connecting holes (11) are uniformly provided on each face, and a groove (12) is also provided on each face, wherein connecting holes (11) on two opposite faces communicate with each other in one-to-one correspondence via the grooves (12) on the remaining four faces, and the connecting member (20) is inserted via the connecting holes (11) on one face and is connected to another basic unit (10) by passing out of the connecting holes (11) on the other opposite face via the grooves (12). The structure not only increases the selectivity of connecting two basic units (10) but in one basic unit (10) also ensures that at least one connecting hole can be connected to another basic unit (10), aiding children in developing the ability to think through problems from multiple perspectives and forging the ability to imagine three-dimensional space.
