Description

The invention relates to puzzle games and is an improvement on a cube puzzle but auth. St. USSR № 1066621.

The aim of the invention is to increase entertainingness by limiting the rotation of the faces.

FIG. 1 shows a cube puzzle, a general view; in fig. 2-5 - central element, central, edge and corner cubes, respectively; in fig. 6 - engagement of two central cubes with a rib cube and a central element; in fig. 7 - engagement of the rib cube with the central and angular cubes.

The cube puzzle contains central 1, edge 2 and angular 3 cubes, central element 4, restrictive rods 5.

The central element 4 has six mounting rods 6. The central cube 1 has the first, second and third holes 7, 8 and 9 on the back face, and the recesses 10 on the side faces and the projections of the U-shaped profile 11 on the side faces. The rib cube 2 has recesses 12 , and on the other side facets x are the grooves 13. The corner cube 3 has guides, projections 14 and a recess 15.

Each central cube 1 is mounted on a corresponding mounting rod 6 of the central element 4. The projections of the L-shaped profile 11 of each central cube 1 are engaged with the grooves 13 of four adjacent rib cubes 2. To fix the engagement on the mounting rods x 6 between the central element 4 and the central the cubes 1 dispose springs 16. The guiding protrusions 14 of each corner cube 3 are engaged with the depressions 12 of three adjacent edge cubes 2. The limiting rods 5 can be installed either in the second 8, or in the third recess of any central rotary cube.

The cube puzzle acts as follows.

When the face is rotated, each rib cube 2, which is engaged with two adjacent central cubes 1, can slide along the projections of the L-shaped profile 11 of one of the central cubes 1, rotating with the other central cube 1 around the axis of the corresponding adjusting rod 6 of the central element 4 Since the angle of the projection arc of the L-shaped profile 11 of the central cube 1 is greater than 45 °, then when the face of the puzzle cube is rotated through a 45 ° angle, the rib cube 2 is held by two central cubes 1.

When the cube-puzzle face is rotated, the protrusion 14 of the corner cube 3 slides along the recess 12 of the corresponding rib cube 2 and, when the face rotates at an angle of 45 °, the projection 14 is engaged with the recess 12 of two edge dice 2, since the angle of the arc of the protrusion 14 and the recess 12 is larger than 45 °. In this case, the protrusion 14 is placed in the recess 10 of the central cube 1, and the protrusion L-shaped profile 11 of the latter is in the recess 15 of the corner cube 3. Thus, any puzzle face consisting of the central 1, four ridge 2 and four corner 3 The cubes can rotate around an axis that passes 5 times through the center of this face and is perpendicular to it.

The cube puzzle is disassembled as follows.

By pressing the front face of the central cube 1, the spring 16 is compressed

0 and the projection of the L-shaped profile 11 is released from the engagement with the recess 13. In this case, any of the four adjacent side cubes 2 can be removed from the structure. After that, two corner cubes can be removed, adjacent-s with the side removed, and so on until the complete disassembly of the cube-puzzle.

The cube puzzle is assembled in reverse order.

Since the cubes can vary by

If the nature of the information applied to them, for example, the color of the faces, then collecting them in the appropriate order, you can set the cube puzzle to any initial state.

If the restriction rods 5 are installed in the second recesses 8 of at least two non-opposite central cubes 1, then these rods, interacting with each other, prevent the respective mutual installation of two adjacent gr, and Q cube-puzzles. Since, in this case, the plane of a certain face cannot be exactly aligned with the planes of the other faces, the rotation of other faces is impossible. This increases the cube-puzzle's entertainingness, as it limits the

5 turns of the cube faces, i.e. some cube puzzle states are prohibited.

On the face of the central cubes 1 can be indicated about the position

 restrictive rods, for example, in the form of arrows. Then the forbidden states will be such for which two any arrows point at each other. If restrictive rods are installed in the third recesses 9 of the central

5 dice 1, the cube puzzle acts in the usual way.
