Preschool constructional toy for children - is based upon cylindrical segments to construct cones cylinders and spheres of different diameters

摘要

A preschool toy for children uses planar segments of various basic shapes that may be combined to form circular discs of different diameters. The different diameter discs so constructed may be used to form cylinders, cones (2) or spheres of different diameters. For a cone a number of discs (21-28) are constructed of gradually increasing diameters. Each disc within the cone may be formed in various ways using triangular segments, semi-circles, parallel segments.
