<p>The three-dimensional jigsaw is a toy made up of several spherical surfaces, preferably 4 spherical surfaces of different diameters, which are situated one inside the other and made up of individual elements, which are mutually joined in such a way that they form an individual spherical surface. The toy's final shape is achieved by joining the housing (3), element (2), and movable elements which are placed within the housing. Element (2) is a spherical segment made up of two neighboring spherical segments (4) of the top half of the sphere and two neighboring segments (4) of the bottom half of the sphere which are mutually shifted by 45°, i.e. the width of one segment of the sphere. Inside the housing (3) there are smaller diameter spheres (5), (6) and (7) with clearance between them, thereby enabling the rotation of each individual spheres within the other in all possible directions. Spheres (5) and (6), depending on the method of realizing the invention, consist of 4 elements or 2 elements, while the smallest diameter sphere essentially makes up an orb (7) considering the fact that it regularly consists of two full elements (8) and (8') (pictures 8, 9 and 10).</p> |
