<p>A two-layer intellectual cube composed of eight movable smaller blocks, each side thereof is divided horizontally and vertically into four areas with different paterns or colors; these smaller blocks can be rotated to change their orientations, so that every side of the intellectual cube can be varied in combination, and this can arouse brains of human to get an intellectual enhancing effet. The feature of such structure is that, the interior portion of a smaller movable block is taken as a reference smaller block which has a triangular axle seat extending from the inner end thereof, an arciform raised rail is provided on the wider area of every one of three surfaces of the triangular axle seat which is provided on the corner formed by three surfaces thereof with three mandrels pivotally provided each with a rotatable block, a receiving space is formed between every rotatable block and its corresponding raised rail to receive many outer anti inner slidable blocks, so that these slidable blocks can be displaced revolvingly about a corresponding mandrel along the track of the corresponding raised rail, in which, each outer slidable block is provided on an outer end thereof with a seat block, and when an outer housing block is provided on each of the smaller movable blocks, the two-layer intellectual square cube is completed. In this way, the present invention can reduce complexity and especially suits little learning children in playing.</p> |
