  • the field of the invention concerne such a logical toy which has got mobile units. They can be displaced as compared to each other and to the core.
  • the proposed logical toy can be applied according to the different rules which can be created by the players, too.
  • the logical toy can also be applied to competitions, group or team games. But first of all it serves the purpose of individual amusement.
  • By means of the invented logical toy depth perception, knowledge of solid geometry and the logical way of thinking can be developed to a great extent.
  • the best known logical toy can be learnt from the patent specification No . 173062 MU PS.
  • the logical toy described in the mentioned patent specification consists of a cubcid. Its plates are formed by small cubes.
  • the movable unit, consisting of small cubes can be turned as compared to a core.
  • the movable unit consists of small cubes which form a plate of the big cube and other components, belonging to this movable unit.
  • each plane consists of nine small cubes.
  • the small cubes are the body elements of the geometric body regarded as the logical toy. According to their position and role three types of body elements i.e. small cubes can be distinguished.
  • corner elements There are corner elements, central unit elements and insert ones being joined to the corner elements.
  • the corner elements can never take the place of insert ones that is also true inversely.
  • the central unit elements are such cubes - small cubes - which are set to the middle of the geometric body's - big cube - plates and they cannot be displaced as compared to the core.
  • the players On applying the briefly described logical toy the players have usually got to arrange the body elements, placed at random, considering the coloured surfaces of the small cubes - as body elements - so that each plate of the geometric body consist of elements of the same colour.
  • each plate of the big cube must consist of small cubes' plates of the same colour.
  • the described logical toy has got a considerable disadvantage,namely that the logical toy's/geometric body's/elements' movement is restricted in different ways. Accordingly, the logical toy, apart from some games, cannot provide any other game possibilities. Therefore the mentioned logical toy soon becomes boring or even dull.
  • the aim of the invented logical aim is to allow following various game rules at different difficulty levels and offer more combination possibilities in comparison to the existing lo gical toys.
  • the invented lo gical toy which allows to achieve the objectives. Its geometric body - in case if the surface or surface parts are asymmetric, - as to the frame of the toy - if it encloses triangular , five-angled or curved surfaces (favourably spherical surfaces) , accordingly, each of its movable units is a pyramid , a truncated pyramid , a sphere slice or a unit near the deformed spherical surface that can be partly covered with a spherical surface . Accordingly, the invented lo gical toy can have three variations. The symmetric geometric bodies differ from each other in the shape of the enveloping plates.
  • Each of the body plates can be modified by colo uring or applying a cover that changes the surface' s original plane or shape .
  • These are generally called plate modifiers.
  • the logical toy' s geometric body can be enlarged or reduced in size as compared to the original plane of the body plate.
  • a way of modifying the invented lo gical toy is to apply multi-colour surfaces to its body plates.
  • the invented lo gical toy can become more complicated if certain marks are applied to the body plates. They can be numbers, figures, different protruding or sunk configurations. Such a configuration can be applied to the body plates e.g. that can be well understood by blind people as well, for they are holes forming braille.
  • Each movable unit of the invented logical toy consists of body elements, different building units or perhaps a rotation axis belonging to them.
  • the invented logical toy also has three types of body elements. Among them the central unit elements is the motion central part of the movable unit. Its motion is highly restricted. The other two body elements are the edge element and plate element. In general it is only the central unit elements that must be connected with the core, whereas the other body elements - i.e. edge elements and plate elements - are fixed by the prevailing adjacent elements by means of their curved surfaces allowing different relative motions.
  • the system of the body elements belonging to the movable units can be considered as the shell of the logical toy's geometric body, because the coherent set of shells form its surface layer.
  • the core inside the geometric body can be accomplished as a solid unit so that only the adjusting gaps, necessary to the displacement be between the core and body elements constituting the shell.
  • the core can also be made in a way that the geometric body of the logical toy form a hollow body. As regards manufacturing, both the body elements and the core can consist of some parts.

  • clamping organs can be pins hose medians do not coincide with that of the rotation axis and the body axis of the geometric body.
  • the clamping organ can be such a pin which is tightly adjusted to the core, whereas its adjustment to the central unit element allows motion.
  • the clamping organ's threaded part can be attached to the threaded hollow of the core and its smooth surface is connected with the central unit element, allowing motion.
  • the essence of one of the invented logical toy's version is that its body plates are triangles that can be attached to some movable units in succession, and each momentary moving unit forms a pyramid together with a group a group of the body plates.
