CONSTRUCTION SET-TYPE TOY Russian patent published in 2007 - IPC A63H33/10 

FIELD: construction sets for children, may be used both as toy and educational set.

SUBSTANCE: toy has a plurality of polygonal parts with connection surfaces capable of connecting with connection surfaces of other parts. Parts have magnetic portion on their connection surfaces, said magnetic portion of part and on connection surface of parts being adapted for connection with one another through magnetic force. Magnetic portion is equipped with magnet having both magnetic poles oriented in different directions. Magnet is placed within magnet receiving slot provided in part, and means for preventing detachment of magnet from slot. Magnet may be rotated within said slot. Means for preventing detachment of magnet from said slot has rotating pin positioned centrally of space between magnetic poles of magnet, and depression for positioning of rotating pin, said depression being provided on inner surface of slot so that rotating pin is in parallel with outer surface of part. Means for preventing detachment of magnet from slot may have two depressions provided on opposite surfaces, centrally of both poles of magnet, and two protrusions serving as rotating pins formed on inner surface of magnet receiving slot and adapted for insertion into two depressions. Arbitrary line connecting centers of two depressions is in parallel with part outer surface. Means for preventing detachment of magnet may have gripping protrusion designed for preventing detachment of magnet and formed in opening of magnet receiving slot. Inner diameter of opening defined by gripping protrusion is smaller than width and length of magnet. Means for preventing detachment of magnet may be made in the form of sealing cover for closing opening of magnet receiving slot, magnet receiving slot and sealing cover being made integral on outer surface of part. Magnet is inserted after cutting of part. Detachment of magnet is prevented by fastening of multiplicity of cut portions on part, said cut portions being identical in shape. Means for preventing detachment of magnet may be formed as member for receiving of magnet inserted into magnet receiving slot and having circular portion whose surface contacts with slot, and closing portion which closes upper opening of circular portion. Magnet receiving member also has fastening means for fastening of magnet within slot.

EFFECT: increased efficiency due to producing of difficult-to-destroy constructions.
