State of the art

A cube-puzzle device is known from the prior art, see CN 204864887 U, publication December 16, 2015, IPC A63F 9/08 (2006/01). The known device contains a central cross, angular, rib and central blocks interconnected with the formation of moving layers in each direction of a three-dimensional rectangular coordinate system.

The above cube performs its function. However, for young children, assembling a well-known puzzle cube can cause difficulties, which will reduce interest in an intellectual toy.

The prior art device is known (see the closest analogue - RU 2644313, IPC A63F 13/00, publ. 08.02.2018), equipped with peripheral elements with flat faces, on the outside of which magnets are mounted with the possibility of rotation around their center. The magnets are made in the form of balls and mounted in spherical nests.

A known device can perform its function and be attractive even to young children. However, this device has a complex structure. In addition, the location of the magnets on the outside of the peripheral elements reduces the reliability of the device, since during its operation the spherical nests can become clogged, which can lead to its malfunction.

It should be understood that specialists in the art will be able to offer other options for implementing the utility model and that some of its details can be changed in various other aspects, without going beyond the essence and scope of the present utility model. Accordingly, the explanatory figures and the detailed description of the cube device are illustrative, but not restrictive.

The inventive device cube 1 (hereinafter - the cube) is made of several mating blocks 2 (see Fig. 1, 2). These blocks 2 may have a different external shape. It is possible that several blocks 2 of a symmetrical or mirror-symmetric shape can be made. However, all the blocks 2, with the correct (structurally defined) layout, form a cube 1.

Blocks 2 can be interfaced (connected) with each other with the possibility of disconnecting from each other during the assembly of cube 1. In the disassembled position of cube 1, blocks 2 are disconnected from each other for the next assembly of the specified cube 1.

Each of the blocks 2 is a device made of several elements. Each of the blocks 2 is made predominantly faceted. The faces 3 of block 2 can be made of the same or different shape, while the faces 3 can differ in size from each other.

Each of the blocks 2 contains an outer 4 and an inner 5 surface. In the process of assembling the cube 1, the blocks 2 are mated with each other by the outer surfaces 4 of their faces 3.

Blocks 2 and their faces 3 may contain internal partitions (not shown in the figures) and / or ribs 6, increasing the rigidity of these blocks 2 (see Fig. 4). In the case of a complex structure of the unit 2, fixing devices or similar devices can be attached to the said internal partitions.

Each of the blocks 2 is equipped with magnets 7 and 8 installed inside the block 2 with the possibility of contact with the inner surface 5 of its faces 3, which allows the mating faces 3 to be attracted to each other during the assembly of the cube 1, and the mating blocks 2 are interconnected using magnetic the forces of these magnets 7, 8 (see Fig. 3-6).

Opposite tubular elements 9 and 10 with openings in which magnets 7 are installed inside each block 2. These tubular elements 9 and 10 are located on the inner surface 5 of two opposite faces 3 of block 2 and are interconnected by a connecting element 11 that prevents the indicated magnets 7 (see Fig. 7). Each of the connecting elements 11 is installed in two holes of the opposite tubular elements 9 and 10.

In each block 2, protrusions 12 are made on the inner surface 5 of its faces 3, each of which forms a free space with the indicated inner surface 5, in which the magnet 8 is located. These magnets 8 can be arranged to move inside these protrusions 12 and can be contacted with inner surface 5.

In each block 2, on the inner surface 5 of one of its faces 3, restrictive protrusions 13 are made, located opposite the protrusions 12 and preventing the exit of magnets 8 from these protrusions 12. The end sections of the restrictive protrusions 13 can be located directly in front of the entrance to the protrusions 12 or inside these protrusions 12 .

The protrusions 12 are elongated and have a U-shaped transverse profile, which allows you to create the above free space for moving the magnets 8. In addition, the above-described implementation of the protrusions 12 increases the rigidity and reliability of the blocks 2, and is also technologically advanced in the manufacture and assembly of these blocks 2.

In each block 2, on the inner surface 5 of one of its faces 3, internal bounding protrusions 16 are made, each of which is located inside the protrusion 12 made on the inner surface 5 of two faces 3 of block 2, in particular on the inner surface 5a and inner surface 5b (see . figure 8). Each internal limiting protrusion 16 prevents contact of the magnet 8 with the inner surface 5 of one of these faces 3, in particular with the inner surface 5a, which is contacted by a magnet 7 installed in the tubular element 9. In this case, said magnet 8 is in contact with the inner surface 5 of the second of these faces 3, in particular with an inner surface 5b.

The above construction ensures the correct positioning of the magnets 7, 8 in the blocks 2 during the assembly of the cube 1. In the process of pairing the blocks 2 between themselves, the magnets 7, 8 of the mating faces 3 move, respectively, in the tubular elements 9 and / or 10, and / or protrusions 12 (depends on which of the faces 3 of blocks 2 the user will mate during the assembly of the cube 1) and are in contact with the inner surface 5 of the indicated mating faces 3. As the mating faces 3 come closer, their magnets are installed at the same level and attracted to each other friend, providing a reliable connection of the blocks 2 among themselves.

The number of tubular elements 9, 10 and protrusions 12 with magnets 7 and 8 installed in them, respectively, depends on the shape of the blocks 2 forming a cube 1. The number of tubular elements 9, 10, protrusions 12 and magnets 7, 8 must be such that blocks 2 reliably connected to each other, forming a cube 1, which does not fall apart and maintains its integrity.

In a specific embodiment, each of the blocks 2 contains a housing formed by a box-shaped element 14 and a removable element 15. Inside the box-shaped element 14 there are protrusions 12 with magnets 8 installed therein, as well as at least one of the tubular elements 9 with a magnet 7.

The specified housing of the block 2 can be made of plastic or other material, to which the magnets 7, 8 are not attracted.

The following describes a specific example of one of the blocks 2 (see figures 4-8). The remaining blocks 2 of cube 1 have a similar design for holding magnets 7, 8.

The box-shaped element 14 of the block 2 contains: a face 3a, on the inner surface 5a of which there are three tubular elements 9 with holes, in each of which a magnet 7 is installed, which is able to contact with the specified inner surface 5a; side faces 3b, in particular six side faces 3b, on the inner surface 5b of which there are eight protrusions 12. Inside each protrusion 12 there is a free space in which the internal limiting protrusion 16 and the magnet 8 are located. These internal limiting protrusions 16 prevent the magnets 8 from contacting the inner surface 5a, while these magnets 8 can be in contact with the inner surface 5b of their corresponding side faces 3b.

The removable member 15 is one of the faces 3 of the block 2, in particular the face 3c located opposite the face 3a of the box-shaped member 14. On the inner surface 5c of said removable element 15, the following are formed: three tubular elements 10 with holes in which magnets 7 are mounted, which are able to contact with said inner surface 5c; eight bounding tabs 13.

In the assembled position of the unit 2, three tubular elements 9 are located opposite three tubular elements 10, with each of the pairs of opposite tubular elements 9 and 10 connected to each other by a connecting element 11. Eight restrictive protrusions 13 of the removable element 15 are located in eight protrusions 12 opposite the magnets 8, preventing them from escaping from said protrusions 12. Thus, a magnet 8 is located between each pair of said protrusions 13 and 16. This design ensures the correct positioning of the magnets 8 in the mating between second blocks 2, which increases the reliability of the construction.

To solve the game, the user must sequentially connect the blocks 2 to each other, filling in the free space until six faces of the cube 1 are formed. In the assembled position of the cube 1, all the blocks 2 are paired with each other by the outer surface 4 of their faces 3.

In case of incorrect installation of one of the blocks 2, it can be quickly disconnected and its position relative to other interconnected blocks 2, or use block 2 having a different external shape, for example, from those shown in figure 2.

To disassemble the cube 1, you need to make little effort to disconnect the blocks 2 from each other, while maintaining the integrity and reliability of each of the blocks 2, which can be used for subsequent assembly of the cube 1.

The above blocks 2 provide a reliable connection with each other with the ability to quickly disconnect the necessary block 2 during the assembly of the cube 1.

The claimed device cube 1 is technological in manufacture, reliable, interesting and attractive, and can be used by people of different ages, including young children.
