<p>A built-up toy includes basic geometric bodies (201, 400, 301, 51, 53) and imitative elements (700, 901, 902, 52). The basic geometric bodies (201, 400, 301, 51, 53) include cuboid, cube, triangle, trapezium, cylinder, cone, prism, pyramid, sphere, ellipsoid or their combinations and geometric bodies cut from them. The imitative elements (700, 901, 902, 52) are appearance-simulating elements of the parts excluding the basic geometric bodies (201, 400, 301, 51, 53) in the model to be built up. The basic geometric bodies (201, 400, 301, 51, 53) and the basic geometric bodies (201, 400, 301, 51, 53), the imitative elements (700,901,902,52) and the imitative elements (700,901,902,52), the basic geometric bodies (201, 400, 301, 51, 53) and the imitative elements (700, 901, 902, 52) are connected through fitting surfaces and coupling devices (91, 92) on the fitting surfaces.</p> |
