PLAYING BALL Russian patent published in 2002 - IPC

FIELD: production of toys. SUBSTANCE: playing ball has two parts made in the form of spherical segments symmetrical with respect to axis of rotation and having single central pin, mid portion (spherical zone) complementary to both spherical segments, guiding slot running circumferentially of ball in plane of larger circle and formed on outer surfaces of both spherical segments and on mid portion, and playing members arranged one after another along perimeter in row within slot. Spherical segments positioned for rotation around central pin are made in the form of cones rigidly connected one with the other with their apexes for joint rotation about central pin so that rotation of one segment automatically causes rotation of other segment in conjunction with one segment. Playing members are formed as disks radially extending outside from guiding slot. Plane of disks coincides with that of large circle so that face of playing members is permanently in the player's field of view. Such construction increases possibilities and versions of playing toys and allows different kinds of puzzle-type toys composed of members movable one with respect to another to be manufactured. The extent of difficulty in such toys may be increased. EFFECT: simplified construction and increased entertaining effect. 14 cl, 16 dwg
