First Claim
Patent Images
1. An animated toy doll, comprising:
- a head including a top and a bottom defining a vertical axis;
plural, changeable-position, movable facial-expression structures pivotally mounted to the head; and
a shared rotary drive device rotatably disposed within the head, wherein the drive device is configured to rotate in plural directions around an upright long axis that is parallel to the vertical axis, and to move each of the facial-expression structures, as the drive device rotates in any one of the plural directions, producing plural position-changing motions in each of the facial-expression structures,wherein the shared rotary drive device includes a cylindrical drive drum body having different-diameter upper and lower portions and configured to rotate around the upright long axis, and wherein the facial-expression structures are configured to pivot around plural pivot axes and the plural pivot axes are at least substantially perpendicular to the upright long axis, and wherein the cylindrical drive drum body is operatively connected to the facial-expression structures such that rotary movement of the cylindrical drive drum body directly translates to pivotal movement of the facial-expression structures.

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.

13. An animated toy doll, comprising:
-
a head including a top and a bottom defining a vertical axis; eye and mouth structures pivotally mounted to the head, wherein the eye and mouth structures are configured to pivot between open and closed positions that are around plural pivot axes; a single shared rotary drive device rotatably disposed within the head, wherein the drive device is configured to rotate around an upright long axis that is parallel to the vertical axis, and wherein the shared rotary drive device includes plural elongate circumferential tracks that are operatively connected to the eye and mouth structures such that rotary movement of the shared rotary drive device translates to pivotal movement of the eye and mouth structures; and a motor disposed within the doll and drivingly connected to the shared rotary drive device, wherein the motor is configured to rotate the shared rotary drive device. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 27)

21. An animated toy doll, comprising:
-
a head including a top and a bottom defining a vertical axis; plural facial-expression structures pivotally mounted and disposed within the head, wherein the plural facial-expression structures are configured to pivot around plural pivot axes at least substantially perpendicular to an upright long axis; and a single shared cylindrical drive drum body rotatably disposed within the head, wherein the drum body is configured to rotate around the upright long axis that is parallel to the vertical axis and to pivotally move each of the plural facial-expression structures, and wherein the shared cylindrical drive drum body includes at least one driver track structure that is operatively connected to the facial-expression structures such that rotary movement of the shared cylindrical drive drum body translates to pivotal movement of the plural facial-expression structures. - View Dependent Claims (22, 23, 24, 25)
