BRAIN-TWISTER

Abstract: Brain-twister (1) consists of movable elements which are arranged into the groups (2) of at least four mutually separated and mutually movable flat elements (3, 4) in the scope of 360 DEG , wherein one element of each group (2) creates a central flat element (3) and at least three orbital flat elements (4) are arranged symmetrically around this central flat element (3), wherein at least one of these orbital flat elements (4) is a part of the same number of orbital flat elements (4) of a neighbour group (2) of flat elements (3, 4) again with a central flat element (3), wherein all the groups (2) of flat elements (3, 4) create an infinite and closed chain in all directions and the chains are arranged into a shape of a ball.

Description: Brain-twister Field of the invention This invention relates to a brain-twister consisting of flat elements movable to each other and arranged as an envelope on a ball-shaped inner construction. Background of the invention There are special toys, which aim is to exercise imagination and combination skill. These brain-twisters are constructed as a group of movable elements and on basis of the possibility to change their mutual position. These elements are usual painted with various colours or their surfaces or segments of a picture are printed on them and the task of the player is to create a geometrical shape or put together a picture by displacement of these elements. These elements can be displaced either individually or in raws or groups. A typical example of a brain-twister of this art is a flat toy created by a frame in which square flat elements are placed but in the frame there is a free square place to enable displacement of one of those elements or of a whole raw of elements. But this is only a simple toy for small children which can not attract the older ones or even adults. A more complicated brain-twister is the so called „Rubic's cube" which was extremely popular in the early eightees. It was a brain-twister of a new generation. 27 colour small cubes is arranged in 3 walls made of 3 x 3 cubes. Each of these three walls represent a group of 9 cubes and this group can by twisted in two perpendicular planes. There are various paints on the small cube ' s surfaces and the task is solved when there are strips of the same colour on the surface of the whole Rubic's cube. But the Rubic's cube has a disadvatageous angular shape and the construction of it is relatively complicated. The aim of the invention is to present a brain-twister with an agreeable spaced shape without sharp edges sufficiently complicated to attract elderly children and adults with the possibility to create pictures or images what can not be achieved in an embodiment with the cube. Technical characteristics of the invention The above mentioned insufficiencies are up to a considerable degree eliminated by a brain-twister according to the invention the subject matter of which is that the movable elements are arranged into the groups of at least four mutually separated and mutually movable flat elements in the scope of 360°, wherein one element of each group creates a central flat element and at least three orbital flat elements are arranged symetrically around this central flast element, wherein at least one of these orbital flat elements is a part of the same number of orbital flat elements of an adjacent group of flat elements again with a central flat element, wherein all the groups of flat elements create an infinite and closed chain in all directions and the chains are arranged into a shape of a ball. In a prefered embodiment there are five orbital flat elements in one group wherein the central flat element has a shape of a regular pentagon and the orbital flat elements have a shape of a regular hexagon. In another prefered embodiment the central flat element is firmly mounted on the ball-shaped inner construction and the orbital flat elements are arranged movable around them and also movable to each other. In another prefered embodiment the central flat elements have smaller real or imaginary diameter than the orbital flat elements. Description of the figures The invention will be illustrated in reference to the drawings where Figure 1 illustrates a view on the planary spread ball-shaped envelope created by circular flat elements according to one embodiment of the brain-twister according to the invention and Figure 2 shows another embodiment of the brain-twister according to the invention but the flat elements are of pentagonal respective hexagonal shape in an arrangement typical for a soccer ball. Examples of the invention embodiment The brain-twister 1 in the prefered embodiment has a ball-shape but due to the better possibility of illustration of the principle Figure 1 illustrates a view on the planary spread ball-shaped envelope created by circular flat elements 3,4. The envelope is covering a ball-shaped inner construction, which is not illustrated, and it is created by groups 2 of flat elements 3,4. These groups 2 consist always of six mutually separated and to each other in the scope of 360° movable flat elements 3,4, wherein one of the elements 3,4 in the group 2 is considered as a central flat element 3 and five orbital flat elements 4 are arranged symetrically around this central flat element 3. How many and what elements 3,4 belong to one group 2 of elements 3,4 is indicated by the closed intermitent loop. The central flat element 3 has in this embodiment a smaller diameter of about 20% than the orbital flat elements 4. The surfaces of all flat elements 3,4 are partly covering each other so the group 2 of the orbital flat elements 4 creates a compact loop around and with the central flat element 3. But there is also an alternative embodiment where all the elements are of the same size and then every flat element 3,4 can represent in a certain moment a central or an orbital one. By a circular movement of the group 2 of the orbital flat elements 4 comes to a mutual displacement of the orbital flat elements 4 into the adjacent groups 2 of other orbital flat elements 4. In principle it is possible to have groups 2 of flat elements 3,4 which consist of at least three orbital flat elements 4 arranged symetrically around one central flat element 3 wherein all four flat elements 3,4 are movable to each other in the scope of 360°. At the same time at least one of the orbital flat elements 4 is a part of a adjacent group 2 of orbital flat elements 4. But is is obvious that by such embodiment there would be relatively great gaps between the orbital flat elements 4 and it would be necessary to fill them because of aestetic reasons. Also by the variante with all elements of the same size there would be a problem with gaps. An advantageous embodiment of the brain-twister 1 is shown in Figure 2. In this case it is again a view on the planary spread ball-shaped envelope created by pentagonal and hexagonal flat elements 3,4. The central flat elements 3 are of a regular pentagonal shape and the orbital flat elements 4 of a regular hexagonal shape. The central pentagonal flat element 3 has also in this embodiment a smaller imaginary diameter of about 20% than the orbital hexagonal flat elements 4. In both embodiments always two of the five orbital flat elements 4 creating a group 2 create a part of an adjacent group 2 of flat elements 3,4 which consists again of five orbital flat elements 4 and of one central flat element 3. All the groups 2 of flat elements 3,4 create an infinite and closed chain in all directions and the chains are arranged into a ball-shaped envelope carried on a ball-shaped inner construction. In both embodiments the central flat element 3 can be mounted firmly on the ball- shaped inner construction and the orbital flat elements 4 are arranged movable around them. But it is possible to use the embodiment without any firmly fastened central flat element 3.
