Abstract

A toy figure is disclosed. In some embodiments, the toy figure may include a head; plural facial-expression structures movably mounted to the head and configured to move independent of each other; plural cams configured to rotate about a first axis and to move the plural facial-expression structures; and an elongate cam drive configured to rotate about a second axis spaced from the first axis, and to contact and rotate the plural cams about the first axis, the elongate cam drive having a constant outer diameter.

Claims

1. A toy figure, comprising:

a head;

plural facial-expression structures movably mounted to the head and configured to move independent of each other;

plural cams configured to rotate about a first axis and to move the plural facial-expression structures; and

an elongate cam drive configured to rotate about a second axis spaced from the first axis, and to contact and to rotate the plural cams about the first axis, the elongate cam drive having a constant outer diameter.

2. The toy figure of claim 1, wherein the plural cams include a drive surface, the elongate cam drive being configured to contact the drive surface of the plural cams and rotate the plural cams about the first axis.

3. The toy figure of claim 2, wherein the drive surface includes a plurality of surface teeth and the elongate cam drive includes a plurality of drive teeth that are meshed with the plurality of surface teeth.

4. The toy figure of claim 1, further comprising plural cam followers configured to connect the plural facial-expression structures and the plural cams, wherein the plural cams include a cam profile surface, the plural cam followers engaged with the cam profile surface and configured to be moved by the cam profile surface of the plural cams.

5. The toy figure of claim 4, further comprising a bias assembly configured to urge the plural cam followers into engagement with the cam profile surface of the plural cams.

6. The toy figure of claim 4, wherein the plural cam followers pivot about one or more pivot axes parallel to the first axis.

7. The toy figure of claim 4, wherein the cam profile surface of one or more of the plural cams includes at least one lobe.

8. The toy figure of claim 1, wherein the plural facial-expression structures include one or more eyebrows configured to move between high and low positions.

9. The toy figure of claim 8, wherein the plural facial-expression structures include one or more eyelids configured to move between up and down positions.

10. The toy figure of claim 9, wherein the plural facial-expression structures include one or more eyeballs configured to move between left and right positions.

11. The toy figure of claim 10, wherein the plural facial-expression structures include a mouth configured to move between open and closed positions.

12. The toy figure of claim 1, wherein the first axis is parallel to the second axis.

21. The toy figure of claim 1, wherein the elongate cam drive is further configured to be in constant contact with the plural cams.

13. A toy figure, comprising:

a head;

plural facial-expression structures movably mounted to the head and configured to move independent of each other;

plural cams configured to rotate about a first axis and to move the plural facial-expression structures, the plural cams having a constant outer diameter;

a single cam drive configured to rotate about a second axis parallel to the first axis, and to contact and rotate the plural cams about the first axis; and

a motor configured to rotate the cam drive about the second axis.

14. The toy figure of claim 13, wherein the plural cams include a drive surface, the single cam drive being configured to contact the drive surface of the plural cams and rotate the plural cams about the first axis.

15. The toy figure of claim 14, further comprising plural cam followers configured to connect the plural facial-expression structures and the plural cams, wherein the plural cams include a cam profile surface, the plural cam followers engaged with the cam profile surface and configured to be moved by the cam profile surface of the plural cams.

16. The toy figure of claim 15, wherein an outer diameter of the cam profile surface is less than an outer diameter of the drive surface.

22. The toy figure of claim 13, wherein the plural cams are further configured to rotate about a cam shaft defining the first axis.

17. A toy figure, comprising:

a head;

plural facial-expression structures pivotably mounted to the head and configured to move independent of each other, the facial-expression structures including one or more eyebrows, one or more eyelids, and one or more eyeballs;

plural cams configured to rotate about a first axis and to move the facial-expression structures, the plural cams having a constant outer diameter and including a drive surface and a cam profile surface;

plural cam followers configured to connect the plural facial-expression structures and the plural cams;

an elongate cam drive configured to rotate about a second axis parallel to the first axis and to contact the drive surface of the plural cams and rotate the plural cams about the first axis, the elongate cam drive having a constant outer diameter; and

a motor disposed within the head and configured to rotate the elongate cam drive about the second axis, wherein the plural cam followers are engaged with the cam profile surface of the plural cams and configured to be moved by the cam profile surface of the plural cams.

18. The toy figure of claim 17, wherein the plural facial-expressions structures further include a mouth.

19. The toy figure of claim 17, further comprising a controller configured to control the motor to selectively rotate the elongate cam drive.

20. The toy figure of claim 17, wherein the constant outer diameter of the plural cams is greater than the constant outer diameter of the elongate cam drive.
