TRAINING TOY Russian patent published in 1997 - IPC

FIELD: production of toys with weight attached to base causing it normally to recover its standing position. SUBSTANCE: toy has body with spherical bases and weight positioned within body for reciprocating along guides from one spherical base to another. Body is made in the form of monolithic body of rotation having plane of symmetry perpendicular to its longitudinal axis and extending through its center of gravity. Guide is formed as channel composed of two parts positioned at an angle one relative to the other in symmetry with respect to body plane of symmetry. Retaining cavities are made in mid portion and ends of channel for retaining weight in stable position. Cavity made in mid portion of body is offset relative to its center of gravity and is positioned in symmetry with its plane of symmetry to enhance stability of body, when weight is fixed in retaining cavities. Weight is formed as ball having surface curvature exceeding that of spherical bases. Retaining cavities in channel ends are positioned in symmetry with longitudinal axis of body. Diameter of mid portion is less than maximum diameter of body. EFFECT: increased efficiency, simplified construction and increased entertaining effect. 1 dwg
