INTERLOCKING CONSTRUCTION BLOCK |
摘要 |
An interlocking construction block has a first, two second and two third parts each having major faces lying in parallel planes. The block is generally V-shaped when viewed normally to the parallel planes and the height of the third parts is only one half of that of the first and second parts, enabling the block to be interlocked neatly with other similar blocks to form a wide variety of structures. |
