Abstract

A toy doll with lips that move as speech sounds are produced from a speaker. Pressing a button on the body of the doll activates an integrated circuit that sends voice signals to the speaker, which transmits the sounds. This in turn actuates a switch, causing a motor to run. The drive shaft of the motor rotates, causing a series of meshing gears to turn. The axle of a gear in the series that passes through the eccentric bore of an internal cam causes the cam to move so that it forces an L-shaped cam follower to rock back and forth about a pivot point. The rotatable pivot rod is supported by the rigid torso of the doll, and one end of the cam follower is attached to the interior of the doll'"'"'s flexible face at a point connecting the two lips. The rocking of the cam follower causes the lips to close and open in a simulation of talking. The motor only runs, and consequently the lips only move, at the same time that simulated speech is transmitted from the speaker. A portion of the doll'"'"'s rigid body that is interior to its flexible head supports the head and prevents the head and face from collapsing or becoming distorted during operation.

Claims

1. A doll with simulated speech and coincident lip movements comprising:

i) a hollow rigid body having a head support portion, the head support portion having an aperture;

ii) a flexible head having a face with lips, wherein the head is mounted over the head support portion so that the head support portion projects into the head and contacts and supports the face, with the lips being positioned over the aperture;

iii) a cam follower having an upper end, a lower end and a fulcrum intermediate between the upper and lower ends, the fulcrum contained in the body and the cam follower being adapted to pivot about the fulcrum backward and forward in relation to the face, and the upper end being attached to an interior portion of the lips such that on backward movement of the upper end, the lips are pulled inwardly, and on forward movement of the upper end, the lips are pushed outwardly to stimulate the appearance of speech;

iv) a cam that produces oscillation of the cam follower;

v) a motor contained in the body that drives the cam;

vi) coupling means coupling the motor to the cam;

vii) sound generating means contained in the body for generating pre-defined speech phrases from the doll;

viii) switch means for activating the sound generating means; and

ix) circuitry means for activating the motor to move the lips coincidentally with the speech phrases.

2. The doll of claim 1, wherein the sound generating means includes a programmable integrated circuit.

3. The doll of claim 2, in which there is means for activating the motor upon activation of the sound generating means.

4. The doll of claim 3, wherein the upper end of the cam follower is attached to the interior portion of the lips at a single place.

5. The doll of claim 4, wherein the cam follower is substantially L-shaped.

6. The doll of claim 5, wherein the cam is internal to the cam follower.

7. The doll of claim 6, wherein the cam has an eccentric bore and the coupling means has an axle that passes through the bore the axle being adapted to turn the cam.

8. The doll of claim 7, wherein the coupling means includes gearing.

9. The doll of claim 1, wherein the switch means includes a pressure-sensitive switch and a switch actuator.

10. The doll of claim 9, wherein the switch actuator includes a push-button on an exterior portion of the doll.

11. The doll of claim 3, wherein the sound generating means includes a speaker.

12. A doll with simulated speech and coincident lip movements comprising:

i) a hollow rigid body having a head support portion, the head support portion having an aperture;

ii) a flexible head having a face with lips, wherein the head is mounted over the head support portion so that the head support portion projects into the head and contacts and supports the face, with the lips being positioned over the aperture;

iii) a substantially L-shaped cam follower having an upper end, a lower end and a fulcrum intermediate between the upper and lower ends, the fulcrum contained in the body and the cam follower being adapted to pivot about the fulcrum backward and forward in relation to the face, and the upper end being attached to an interior portion of the lips at a single place such that on backward movement of the upper end, the lips are pulled inwardly, and on forward movement of the upper end, the lips are pushed outwardly to simulate the appearance of speech;

iv) a cam that produces oscillation of the cam follower, the cam being internal to the cam follower and having an eccentric bore;

v) a motor contained in the body that drives the cam;

vi) coupling means coupling the motor to the cam, the coupling means including gearing and an axle that passes through the eccentric bore, the axle being adapted to turn the cam;

vii) sound generating means contained in the body for generating pre-defined speech phrases from the doll, the sound generating means including a programmable integrated circuit;

viii) switch means for activating the sound generating means; and

ix) means responsive to the sound generating means for activating the motor to move the lips coincidentally with the speech phrases wherein the motor is activated upon activation of the sound generating means.

13. A doll with simulated speech and coincident lip movements comprising:

i) a hollow rigid body having a head support portion, the head support portion having an aperture;

ii) a flexible head having a face with lips, wherein the head is mounted over the head support portion so that the head support portion projects into the head and contacts and supports the face, with the lips being positioned over the aperture;

iii) a cam follower having an upper end, a lower end and a fulcrum intermediate between the upper and lower ends, the fulcrum contained in the body and the cam follower being adapted to pivot about the fulcrum backward and forward in relation to the face, and the upper end being attached to an interior portion of the lips at a single place such that on backward movement of the upper end, the lips are pulled inwardly, and on forward movement of the upper end, the lips are pushed outwardly to simulate the appearance of speech;

iv) a cam that produces oscillation of the cam follower;

v) a motor contained in the body that drives the cam;

vi) coupling means coupling the motor to the cam;

vii) sound generating means contained in the body for generating pre-defined speech phrases from the doll;

viii) switch means for activating the simulated speech and coincident lip movements; and

ix) means for activating the motor to move the lips coincidentally with the speech phrases.
