FLAT ARTICULATED DOLL NAMED "RUSSIAN BALLERINA" Russian patent published in 1997 - IPC

FIELD: construction of movable and dancing lever-controlled figures. SUBSTANCE: doll has plane motion kinematic members, whose operation is based on theory of curves. Left leg 3 of doll is rigidly fixed on screen 7 and its body is pivotally attached at point A. Doll leverage system has drive lever 8 and row of links, which are pivotally connected one with the other and with movable members: drive link LATB, from which motion is transmitted to all other links of leverage system; link CBE for controlling motion of leg 4; manual control levers LM and OT; body motion control link KGA. Simulation of natural motions of human body is further facilitated by double-crank transmission four-link member ABCD, single-crank four-link member DNKA and two links ROS and PFM. Lever 8 makes continuation of drive link LATB. When lever 8 is depressed, drive link LATB is urged to rotate about point A through 152 deg. Moving doll-ballerina may be fixed in any effective pose imitating ballerina motions within the range of 0 to 152 deg. EFFECT: increased entertainment effect by improved imitation of natural motions of human being. 2 cl, 8 dwg
