<p>Three-dimensional logical toy formed by surrounding solid and internally arranged movable, but non-removable sectional bodies and central control body or bodies. The limiting surfaces of the sectional bodies are marked with letters, numbers or other symbols and in given case with colours representing the symbols. The three-dimensional logical toy is aimed at ordering the symbols to each other according to a fixed method, or at reproducing a fixed order following its optional upsetting by movement of the sectional bodies. The rotatable central control body and the movable sectional bodies complement each other as a body of rotation, several such bodies of rotation are non-removably implanted into the surrounding solid, the surrounding solid is provided with one or several holes allowing the manipulation of the bodies of rotation formed by the rotatable central control body and movable sectional bodies, the movable sectional bodies are essentially of the same size arranged along the inner limiting surface as on control track of the surrounding solid, and bodies having at least two convex surfaces suitable for the simultaneous rotation along the limiting surfaces in contact with the rotatable central control body, while the rotatable central control bodies have concave surfaces matching the convex surfaces of the movable sectional bodies.</p> |
