Abstract (en)
This disclosure relates to a changeable maze pattern structure, comprising pathways A1-A3, B1-B3, C1-C3, D1-D3 leading in different directions (A,B,C,D), an open space (2) within the maze connected to the pathways, and screens (4) having a common fulcrum (3) at the center of the open space (2). The screens (4) face generally in the various directions of the pathways, and the interconnection of the pathways, which are connected to each other via the open space, (2) is capable of being changed by the rotation of the screens (4), thus changing the maze pattern.
