[Prior art]

 FIG. 1 shows a well-known combination educational block toy called a cubic game. It has a three-layer structure with nine active surfaces on each of the six sides of cube A. In general, one color is painted on the six sides of cube A, that is, the nine active surfaces on the same surface have the same color area. By rotating one of the active surfaces, the other active surfaces around the active surface move into a different color area, so that the color of the area becomes congested. The method of the game is to condense all six colors of cube A, then rotate each layer to concentrate the active surface of the same color on one of them, and finally all cubes A The six combined planes are each returned so that they are composed of the same colored active plane.

[0003] The biggest drawback of the well-known three-layer combination block educational toy described above is that it is too complicated and suitable for adolescents and adolescents, but for those who are not very patient, it takes about 2 hours to complete the reassembly. Otherwise, they tend to abandon, especially for toddlers and children, who may not even know how to play.

[0004] In view of the shortcomings of the well-known three-layer combination block educational toy described above, the present inventors have studied how to reduce the complexity of the combination block educational toy. The most direct idea is to simplify the three-layer structure to a two-layer structure, that is, to combine one combined surface with only four small active surfaces. However, as a result of research and development, it turned out to be very difficult to implement, and that is the reason that the double-layer combination block educational toys have not yet been found on the market.

First, the structure of a well-known three-layer combination block educational toy will be described. The components are as shown in FIG. 2 and include one cross axis 1, six rotating blocks 2, twelve corner blocks 3, and eight corner blocks 4.

[0006] The cross axis 1 is connected so that the midpoints of the center axes of three different vertical axes cross each other, and the outer end of the cross axis 1 has six different directions. A connection end 5 is formed.

The rotating blocks 2 are respectively connected to one connecting end 5 of the cross shaft center 1, so that each one rotating block 2 corresponds to the center of each of the six combined surfaces of the cube A. Its shape is substantially T-shaped, and its plane is turned outward so as to be rotatable.

The side corner block 3 is provided between two mutually adjacent rotating blocks 2, the front rotating block 2 is used as a reference block, and the upper and lower and left and right adjacent rotating blocks 2 are connected to each other. In between, four corner blocks 3 are placed. Similarly, four corner blocks 3 are installed between the rotating block 2 on the rear side and the other four rotating blocks 2, and one between the four rotating blocks 2 adjacent to each other vertically and horizontally. The corner blocks 3 are placed, and a total of 12 corner blocks 3 are provided.

The corner end block 4 is provided between each two adjacent side corner blocks 3, and a total of eight corner end blocks 4 are provided, each constituting eight corner ends of the cube A, and the corner angles The block 3 jointly surrounds the periphery of the rotating block 2, and even if any one of the three-layer combination block educational toys is rotated, the rotating block 2 rotates at its origin, and the corner end block 4 and the side corner block 3 become corners. It rotates around the end block 4.

The above-described three-layer combination block educational toy composed of the above-described cross shaft center 1, a plurality of rotating blocks 2, side corner blocks 3 and corner end blocks 4, has six connecting ends 5 in the cross shaft center 1. Any one end of the cube may be the central active plane of the corresponding active planes, i.e. the axis of the rotating block, so that each one of the six faces of the cube is exactly Have 3 × 3 = 9 active surfaces.

However, in order to use the above-described cross shaft center 1 as the center of the two-layer combination block educational toy, the connecting end located at the center point of the six planes is set as the center of each one plane. The interior corner intersection of the four active surfaces of the surface cannot be located at the central active surface of the nine active surfaces as in the three-layer combination block educational toy, so that the cross axis 1 is a two-layer combination. It was not feasible to use a method that is the center of block educational toys, so it was necessary to design a new structural form.
