Description

The technical solution relates to the field of intellectual toys, in particular, to three-dimensional puzzle cubes.

Prior art

The prior art known three-dimensional puzzle cubes, called the magic cube or Rubik's cube. This usually refers to a 3 × 3 × 3 cubic containing three layers in each direction of a three-dimensional rectangular coordinate system. Such a cube contains on each face nine flat surfaces, each of which is usually painted with one of the six primary colors. The speed of assembly of the cube can be affected by the design of the blocks forming the specified cube, their relationship with each other, the presence of lubricant and other factors.

The device of the magic cube, known from CN 204864887 U, publication 12/16/2015, IPC A63F 9/08 (2006/01), containing corner, rib and central blocks, is taken as the closest analogue, while the rib blocks are located between the corner blocks, and the blocks are located in the center of the faces of the cube and are connected to the central crosspiece. Each of the corner and rib units contains a one-piece bowl-shaped body, made hollow and connected to a removable lid.

The above cube can perform its function, however, with weakened screws, by means of which the central blocks are connected to the central cross, the corner and rib blocks can fall out during the cube assembly process. In addition, in the process of high-speed assembly, as layers are rotated, a clear alignment of the cube faces does not always occur, and the player has to spend extra time aligning them to continue assembling the cube until each of its faces becomes monochrome

It should be understood that experts in the field of technology will be able to offer other options for the implementation of the utility model and that some of its details can be changed in various other aspects, without going beyond the nature and scope of this utility model. Accordingly, the explanatory figures and the detailed description of the cube device are illustrative, but not restrictive.

The inventive device of the cube 1 (hereinafter - the cube) contains three layers in each direction of the three-dimensional rectangular coordinate system.

Cube 1 contains: corner blocks 2; rib blocks 3; central units 4; a central cross 5, made three-dimensional with protrusions 5a (see figures 1-2).

The rib blocks 3 are located between the corner blocks 2, and the central blocks 4 are located in the center of the faces of the cube 1. Each central block 4 is rotatably connected with a protrusion 5 corresponding to it and a central cross 5.

Due to the fact that the cube 1 contains six faces, the six central blocks 4 are connected to the corresponding protrusions 5 a of the central cross 5. The connection is made by fastening devices, such as screws or bolts.

For the convenience of understanding the claimed device, the following terms will be used in the description: “rotating layer”, which is extreme, and “middle layer” of cube 1. During the assembly process of cube 1, corner 2 and rib 3 blocks of the rotating layer move relative to rib 3 and central 4 blocks of the middle layer, while the rib blocks 3 of the rotating layer are mated with the rib blocks 3 of the middle layer.

Each corner unit 2 includes a housing 6 connected to a removable cover 7, a rack 8 with an extended lower section 9. The housing 6 of the corner unit 3 is made solid and hollow, while it contains three faces 10 with outer 10a and inner 10b surfaces (see FIG. 2 3, 5).

Each rib unit 3 comprises: a housing 11 connected to a removable cover 12; two oppositely directed lateral protrusions 13; two arcuate grooves 14, bounded below by a lower limiting protrusion 15. Under each lateral protrusion 13 a downwardly wedge-shaped section 16 with inclined lower part 16a may be located. The housing 11 of the rib unit 3 is made integral and hollow, while it contains two faces 17 with outer 17 a and inner 17 b surfaces (see Figures 1, 2, 4, 6).

The corner 2 and rib 3 blocks of the cube 1 are equipped with magnets 18 installed inside the respective housings 6 and 11. In the corner block 2 the magnets 18 are fixedly mounted on the inner surface 10b of three faces 10, and in the rib block 3 the magnets 18 are fixedly mounted on the inner surface 17b of two faces 17 (see figures 5, 6).

It is advantageous to introduce magnets 18 into the body of faces 10 and 17 of the respective bodies 6 and 11, which allows, with relatively small overall dimensions of magnets 18, to clearly fix the corner blocks 2 relative to the rib blocks 3.

The magnets 18 are cylindrical in shape and installed in the corresponding depressions (not shown in the figures), which are mainly cylindrical in the body of the faces 10 and 17 of the respective housings 6 and 11 on the side of their inner surfaces 10b and 17b.

The magnets 18 can be fixed by means of adhesive substances, which virtually eliminates their detachment from the faces 10 and 17.

Permanent magnets can be used as magnets 18.

The above design of cube 1 refers primarily to three-dimensional logical 3 × 3 × 3 puzzle toys and contains eight corner 2, twelve rib 3 and six central 4 blocks that form six faces of the cube 1. The above corner 2, rib 3 and central 4 blocks are reliably connected between itself, forming a solid and reliable construction of the cube 1.

In the assembled position of the cube 1, the lower sections 9 of the corner blocks 2 are installed in the arcuate grooves 14 of the rib blocks 3, filling almost the entire free space of the arcuate grooves 14; the lateral protrusions 13 of the rib blocks 3 are pressed by the central blocks 4, overlapping with their bottom sections the upper surfaces 13a of said lateral protrusions 13. The edges 10 of the corner blocks 2 are mated with the edges 17 of the rib blocks 3, while the outer surfaces 10a contact with the outer surfaces 17a. In this position, the above mating faces 10 and 17 are attracted to each other by means of magnets 18, located almost opposite each other and as close as possible to each other (see figure 7). This ensures smooth and rapid rotation of the layers of the cube 1.

To solve the game, the user must rotate the layers of cube 1 so that, ultimately, each face of cube 1 becomes monochromatic.

In the process of assembling the cube 1, the angular 2 and rib blocks 3 of the rotating layer move relative to the rib 3 and central 4 blocks of the middle layer. The lower sections 9 of the corner blocks 2 of the rotated layer freely and smoothly exit the arcuate grooves of the 14 rib blocks 3 of the middle layer and move under the central blocks 4 of the middle layer. And the lateral protrusions of the 13 rib blocks 3 of the rotating layer, pressed by the central blocks 4 of the middle layer, move with wedge-shaped sections 16 into the arcuate grooves 14 of the rib blocks 3 of the middle layer, each of the above-mentioned wedge-shaped section 16 being as close as possible to the upper surface 15a of the lower restrictive protrusion 15 rib unit 3 of the middle layer or in contact with the specified upper surface 15a, which ensures the accuracy of the relative positioning of the mating rib blocks 3. When the corner The blocks 2 of the rotating layer begin to mate with the edge blocks 3 of the middle layer, their mating faces 10 and 17 are attracted to each other with the help of magnets 18, and when these magnets 18 are as close to each other as possible, a clear alignment of the faces of the cube 1 occurs almost automatically, that will allow the player not to spend extra time on aligning the faces and continue further assembling of cube 1 until each of the faces becomes one-color.

The above design allows you to increase the assembly speed of the cube 1, is notable for its reliability, since the possibility of falling out of the cube 1 of the corner 2 and / or edge blocks 3 is minimized even at the speed assembly of the specified cube 1.
