1. An animated toy doll comprising:
- a hollow doll head component, a first, changeable-position, movable facial-expression structure movably mounted on said head component, a second, changeable-position, movable facial-expression structure movably mounted on said head component, and a single, shared, rotary drive device rotatably disposed within said head component and operatively drivably connected to said facial-expression structures, whereby rotation of this device produces defined, coordinated, related, respective position-changing motions in said structures;
wherein said-drive device includes a plurality of cylindrical elements, operatively connected and configured in a co-axial relationship, said first changeable-position, movable facial-expression structure operatively drivably connected to one of said cylindrical elements, and said second changeable-position, movable facial-expression structure operatively drivably connected to a second cylindrical element.

Abstract
A tiny articulation eye and mouth (facial-expression structures) opening and closing structure installable in the hollow interior of a doll head, and utilizing a single, upright-axis motor, and a rotary, co-axial, stepped-diameter drive drum which is rotated by the motor. Circumferential drive tracks formed on the outside of the drum drive followers and actuation which directly impart opening and closing motions in the doll head'"'"'s eyes and mouth.

7. An animated toy doll comprising a hollow doll head component, generally vertically reciprocable, openable and closable eye and mouth structures movably mounted on said head component, a single, shared, rotary drive device rotatably disposed within said head component and operatively, drivably connected to said eye and mouth structures, whereby rotation of this device produces defined, coordinated, related, respective opening and closing motions in the eye and mouth structures, and a single, selectively power-operated drive motor disposed within said head component and drivingly connected to said drive device, operable to rotate said device;
- wherein said drive device includes a substantially elongate, upright-axis, cylindrical body having upper and lower cylindrical ends, which body has an axial length and is mounted within the head component for rotation about its upright long axis, and a pair of elongate, motion-promoting, substantially circumferential drive tracks formed, one each, on an outside of a different one of said ends, with each track being an associated track operatively associated with a different one of said eye and mouth structures.

12. An animated toy doll comprising a hollow doll head component, generally vertically reciprocable, openable and closable eye and mouth structures movably mounted on said head component, and a single, shared, rotary drive device rotatably disposed within said head component and operatively, drivably connected to said eye and mouth structures, whereby rotation of this device produces defined, coordinated, related, respective opening and closing motions in the eye and mouth structures;
- wherein said drive device includes a substantially elongate, upright-axis, cylindrical body having upper and lower cylindrical ends, each end having an outside, which body has an axial length and is mounted within the head component for rotation about its upright long axis, and a pair of elongate, motion-promoting, substantially circumferential drive tracks formed, one each, on the outside of a different one of said ends, with each track being an associated track operatively associated with a different one of said eye and mouth structures.

17. An animated toy doll comprising:
-
a hollow doll head component, generally vertically reciprocable, openable and closable eye and mouth structures movably mounted on said head component, and a single, shared, rotary drive device rotatably disposed within said head component and operatively, drivably connected to said eve and mouth structures, whereby rotation of this device produces defined, coordinated, related, respective opening and closing motions in the eye and mouth structures;
wherein said drive device is configured to produce, with its rotation, a pattern of related eye and mouth openings and closings in plural, successive, cyclic phases, including both (a) phases in which one only of the eye or mouth structures is shifting in some manner between open and closed conditions, while the other structure retains a non-changing condition, and (b) phases in which both eye and mouth structures retain non-changing conditions. - View Dependent Claims (18, 19)
