Logical plaything for improving spatial orientation and joint for coupling flexible plates

摘要: The invention relates to spatial figure, figural arrangement or logical plaything for improving stereoscopic vision comprising bordering lattice plates (2) in a parallelepipedon form, wherein movable elements (1) being of nearly similar form the enclosed space are accommodated. number one piece less than having room available space. Movable distinguished by symbols, colours. compressed while assembling and pressing flexibly each other (2). keep their position against weight. A coupling means is also disclosed joining up angularly flexible plates, which consists ribs (14) parallel with plane plate perpendicular slots (12). These arranged on edges alternatingly can be snapped other.
