Description

The technical solution relates to the field of intellectual toys, in particular, to three-dimensional puzzle cubes 7⋅7⋅7.

Prior art

Three-dimensional puzzle cubes, called magic cubes, are known in the art. These cubes also include cubes 7⋅7⋅7, which contain forty-nine flat or convex portions on each of their faces. The cube assembly speed can be affected by the design of the mechanism of rotation of the layers, the design of the blocks forming the specified cube, their relationship with each other, the presence of lubricant and other factors.

As the closest analogue, a volumetric cube-shaped puzzle, known from RU 2110310 C1, publication 05/10/1998, IPC A63F 9/12 (1995.01), was adopted. The specified device contains three mutually perpendicular groups of layers, each of these groups includes seven layers: a central layer, two outer layers and four intermediate layers. The famous cube contains eight corner blocks, sixty edge blocks and one hundred fifty central blocks. The lower shaped sections of these blocks are formed by a rotation mechanism, equipped with a central cross, made three-dimensional with six protrusions connected by screws with the corresponding central blocks of the central layers of the cube. The famous cube can perform its function.

However, the design of these angular and edge blocks does not allow for the speed assembly of the cube, during which 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 monochromatic.

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 referred to as the cube) contains angular 2, edge 3 and central 4 blocks forming seven layers in each direction of the three-dimensional rectangular coordinate system (see Fig. 1). Each of the three mutually perpendicular groups of layers contains: a central layer L; two outer layers W; four intermediate layers, two first I of which are located on opposite sides of the central layer L, and two second II are located next to the outer layers W of the cube 1 (see Fig. 2).

In the specific example of performance, the claimed cube 1 contains eight corner blocks 2, sixty rib blocks 3 and one hundred fifty central blocks 4. On the outer side of the cube 1, there are five rib blocks 3 between each two corner blocks 2, and on each of the six faces of the cube 1 located on twenty-five central blocks 4.

Inside the cube 1, a central cross is installed (not shown in the figures), made three-dimensional with six protrusions connected to six central blocks 4a of the central layers L of the cube 1. In a specific example of execution, said connection of the six projections of the central cross to the central blocks 4a of the central layers L of the cube 1 can be carried out by means of fasteners, for example screws.

Each of the rib blocks 3a of the central layers L of the cube 1 contains a lower protrusion 5 forming two restrictive portions 6 protruding in opposite directions that prevent the angular blocks 2 from moving towards the center of the cube 1 (see Figs. 3, 4). This design improves the reliability of the cube 1, because it minimizes the possibility of disconnecting the restriction sections 6 from the specified rib unit Over in cases where the specified restriction sections 6 perceive an increased load, as well as, for example, when cube 1 hits a hard surface.

Each of the corner blocks 2 of the cube 1 contains: a housing 7 with three outer edges, which, as a rule, can be painted or marked in three different colors, and three edges 7a for conjugation; an extended lower part 8 with a lower peripheral portion 8a directed toward the center of the cube 1.

Each of the rib blocks 3 of the cube 1 includes a housing 9 with two outer edges, which, as a rule, can be painted or marked in two different colors, and two edges 9a for conjugation.

In the assembled position of the cube 1 or in the process of its assembly, the lower peripheral sections 8a of the corner blocks 2 can contact or contact the upper surface 6a of the restrictive sections 6 of the lower projections 5 of the rib blocks 3a of the central layers L of the cube 1, which ensures a stable structural position of the corner blocks 2, minimizes the possibility of wedging the above layers W, L, I, II and increases the assembly speed of the cube 1.

Corner 2 and rib 3 blocks of the cube 1 are equipped with magnets 10 mounted inside the housings 7 and 9, respectively (see Fig. 5-8). In the specific example of performance, eight corner 2 and sixty edge 3 blocks of cube 1 are equipped with magnets 10.

On the inner surface 7b of the three faces 7a of the housing 7 of each corner block 2 and the inner surface 9b of the two opposite faces 9a of the housing 9 of each rib block 3 of the cube 1, the magnets 10 are fixedly mounted with which the matings during rotation / rotation of the layers W, L, I, II cube 1 the above edges 7a, 9a are attracted to each other, while ensuring unrestricted rotation of these layers W, L, I, II of cube 1.

When the magnets 10 of the mating faces 7a, 9a are as close to each other as possible, there is, almost automatically, a clear alignment of the faces of the cube 1.

The magnets 10 allow you to make the rotation of these layers W, L, I, II clearer and more controlled. This design allows the player to not spend additional time on the specified alignment and continue the further assembly of cube 1 until each of its faces becomes monochromatic.

It is advantageous to introduce magnets 10 into the body of faces 7a and 9a of the above buildings 7 and 9, respectively, from the side of their inner surfaces 7b and 9b, respectively.

The magnets 10 can be made cylindrical in shape and installed in the corresponding depressions (not shown in the figures), made predominantly of a cylindrical shape in the body of the faces 7a and 9a of the bodies 7 and 9, respectively.

The magnets 10 can be fixed by means of an adhesive substance, which practically excludes their detachment from the above-mentioned faces 7a and 9a of the bodies 7 and 9, respectively.

As magnets 10, permanent magnets can be used.

The rib 3a and central 4a blocks of each of the central layers L of the cube 1 contain protrusions 11 and 12 on opposite sides, respectively, forming two oppositely arranged annular portions 13 installed in the response annular recesses 14 of the nearest intermediate layers, in particular the first intermediate layers I of the cube 1 The annular recess 14 is formed by the grooves 15 and 16 of the rib 3b and central 4b blocks, respectively, This design contributes to the smoothness of rotation of these layers, minimizes the possibility of jamming, which increases It cube assembly speed 1.

The above-described construction of cube 1 is distinguished by its reliability, smoothness of rotation of the layers, fast and precise alignment of the faces, which allows to increase the speed of rotation of these layers W, L, I, II when assembling speed cube 1, namely cube 7⋅7⋅7.
