The obj ect consists of 12 pentagons of various colours and they are held and moved by two kinds of holding parts (male and female) and springs. The purpose of the invention is to eliminate the problems of the known solutions and to implement a icosidodecahedron-shaped logic device that is an aesthetic and fairly complex puzzle, which can be rotated any number of times due to its novel mechanical design, and in which the parts can be placed into various positions relative to each other.

The inventive step is based on the recognition that an invention that is more advantageous than the previous ones can be realized if the invention is implemented according to claim 1. This recognition makes it possible to place to parts of the same shape next to each other, i.e. to place a pentagon next to, for example, another pentagon.

According to our goal, the most general implementation form of the invention is described in claim 1. The most general form of the application procedure is described in the main procedural claim. The various implementation forms are described in the sub-claims. In general, the solution is a 3D logic game, which has six rotational axes, an internal core, and cover components that surround the internal core and can be moved relative to each other. A distinctive feature of the invention is that its overall shape is an icosidodecahedron, it has a rail part, the cover components consist of twelve pentagon parts and twenty triangle parts, and the pentagon parts consist of a pentagon top part, a pentagon bottom part, and a pentagon middle part, and the triangle parts consist of a triangle bottom part, a triangle middle part, and a triangle top part, and the pentagon middle part includes a moving part, and the moving part includes a spring part, and one of the pentagon parts is a fixed pentagon part.

In another implementation form, a rail holding tube and a pentagon holding tube is mounted onto the internal core, and the fixed pentagon part is fitted with a pentagon holder, and the rail is fitted with a rail holder, and the rail is connected to the internal core through the rail holder and the rail holding tube, and the fixed pentagon part is connected to the internal core through the pentagon holder and the pentagon holding tube.

It can be also a distinctive feature that the width of the triangle middle part is smaller than the triangle bottom part and/or the triangle top part, and the width of the pentagon middle part is smaller than the pentagon top part and/or the pentagon bottom part.

In another implementation form, the moving part has a slot, the pentagon middle part has a pin, and the pin and the slot are connected so that they can move relative to each other.

It can be also a distinctive feature that the pentagon part has five spring parts, five pins, and five moving parts.

In another implementation form, one part of the pentagon part is fitted with a stand.

It can be also a distinctive feature that there are twenty rail parts.

In another implementation form, the moving part has a spring tube, and the spring part is connected to the spring tube. In another implementation form, the covering surfaces of the pentagon parts and the triangle parts are arched, and they form a sphere together.

The invention is presented in more detail using drawings relating to its implementation forms.

The invention is a 3D logic game with an overall shape of an icosidodecahedron, which has an internal core and moving triangle and pentagon shaped cover components, as well as fixed rail parts between the two.

For the sake of simplicity, Figure 1 shows the icosidodecahedron proj ected onto a spherical surface, showing the rotational axes 1 and the section planes 2. The surface of the icosidodecahedron consists of twelve pentagons and twenty triangles. This means that the figure shows a spherical icosidodecahedron, but it is true for an icosidodecahedron that two triangles and two pentagons meet in each vertex of the obj ect, and one triangle and one pentagon meets at each edge of the obj ect. The device has six rotational axes 1 , and the direction of each axis is indicated on the drawing. The rotational axes 1 (A, B, C, D, E, F) pass through the centres of opposing pentagons. For each rotational axis 1 , there is a perpendicular section plane 2 that divides the icosidodecahedron into two. The device can be rotated along these section planes 2 so that one half of the icosidodecahedron stays in place, while the other half turns around the respective rotational axis 1. If the rotation angle is 72°, or a multiple thereof, to the left or to the right, the icosidodecahedron is returned to its icosidodecahedron shape, so that the parts of each half of the obj ect are moved into a new position after the rotation, while the overall shape of the object remains unchanged. The rotation can be executed and repeated in any order and any number of times along each of the six rotational axes 1 and the corresponding section plane 2.

Figure 2 shows the internal core 3, and the rail holding tubes 4 and pentagon holding tubes 5 thereon. The internal core 3 is a solid sphere from which the tubes, i.e. the fixed pillars used to hold the rail parts and the pentagon parts, protrude. The device has one pentagon holding tube 5, which is suitable to hold the fixed pentagon part, and twenty rail holding tubes 4, which are suitable to hold a total of twenty rail parts.

Figure 3 shows the rail part 6. The rail part 6 is a triangle shaped part with an arched surface, which is fitted with a rail holder 7. The rail holder 7 can be inserted into a suitable holding tube.

Figure 4 shows how narrow slits, the rails, appear between the rail parts 6 placed into the rail holding tubes 4 of the internal core 3. It is also visible that the fixed pentagon part 8a can be inserted into the pentagon holding tube 5 protruding from the internal core 3 using the pentagon holder 9.

Figure 5 shows the components of the pentagon part 8 on an exploded 3D drawing. Among the twelve pentagon parts, there are eleven moving pentagon parts 8 and one fixed pentagon part. The pentagon holder 9 is connected to the fixed pentagon part, the other parts have stands 10, with the help of which they can move along the paths or rails defined by the rail parts. Each pentagon part 8 consists of a pentagon bottom part 1 1 , a pentagon middle part 12, and a pentagon top part 16. The key to the new mechanical design is that the moving parts 14 can slide into the pentagon middle part 12, thereby making it possible for two pentagon parts 8 to be moved next to each other. The moving parts 14 are fitted with spring parts 15 and slots 22. The pin 13 fits into the slot 22, so that they can move and slide thereon. As a result of the spring parts 15 and the pins 13, the moving parts 14 can fully slide into the pentagon middle part 12, so that they do not hang out any more than the pentagon bottom part 1 1 or the pentagon top part 16, meaning that they do not block each other during rotation. During the transformations and rotations, the fixed pentagon part stays with the internal core and the other pentagons and triangles belonging to the same half of the obj ect, and the other half of the obj ect moves along the paths defined by the twenty rail parts mounted onto the internal core. There are various technical ways to implement the moving part 14, the springy design is the key, so that they can allow the pentagon parts 8 to turn.

Figure 6 shows a 3D view of the triangle part 23. The triangle part 23 consists of a triangle bottom part 17, a triangle middle part 18, and a triangle top part 19. The triangle middle part 18 is smaller than the triangle bottom part 17 or the triangle top part 19, meaning that the moving part shown on the previous drawing can move there.

Figure 7 shows the movement of the moving part 14. The drawing shows a pentagon part 8 and a triangle part 23 next to each other, focusing on the pentagon middle part 12 and the triangle middle part 18. It shows the pentagon bottom part 1 1 and the triangle bottom part 17, which are larger than the pentagon middle part 12 or the triangle middle part 18 above them. The moving part 14 is fitted with a slot 22 and a spring part 15 located in the spring tube 21. The pin 13, which restricts the movement of the moving part 14, fits into the slot 22. In a relaxed state, the triangle parts 23 are kept in place by three moving parts 14.

Figure 8 shows the moment when identical parts are moved next to each other, e.g. a pentagon part 8 is placed next to a pentagon part 8. The triangle parts 23 are of a negative type and do not raise any collision related problem when meeting each other. The main novelty of the solution is that even pentagon parts 8 (positive type) can rotate next to each other. As clearly shown on the 3D drawing, the moving parts 14, due to the springy design, can move into the pentagon part 8, thereby allowing for unobstructed movement, or into the triangle parts 23, thereby connecting the parts temporarily. Due to the arched design of the moving parts 14, it is very easy to rotate one of the semi-spheres along any of the rotational axes, and the inward and outward movement of the moving parts 14 is repeated multiple times during each rotation. During rotation, the triangle parts 23 are held in place the moving part 14 of two pentagon parts 8. In the presented implementation form, the triangle parts 23 are regular triangles, and the pentagon parts 8 are regular pentagons. The moving parts 14 can have any other shape as long as they are capable of moving in and out of the pentagon middle part 12.

Figure 9 shows the rail parts 6. The pentagon parts move on the paths between the rail parts 6 using the stands 10, and the possible directions of movement are marked by the arrows showing the direction of movement 20.

The game described above has numerous advantages. An advantage of the invention is that it can be manufactured in any size, and it is an aesthetically pleasing logic game that can be used to develop logical and spatial skills. It can have any colour or decoration, meaning that it can be used as a puzzle as well. An advantage of the solution is that it can be rotated in any number of positions, and any part can be placed next to another part. The game is easy to rotate and is portable, it consists of simple parts, and its weight is small.

The invention can be applied on the field of education, and logical and spatial- logical games and puzzles. In addition to the above examples, the invention can be implemented in other forms and with other manufacturing processes within the scope of protection.
