Claims
- 1. A doll with an eyeblink mechanism, comprising:
- (A) an eye with a reciprocatable eyelid movable between an eye open position and an eye closed position;
- (B) drive means for providing intermittent slow rotary motion;
- (C) driven means for intermittently relatively rapidly reciprocating said eyelid to blink said eye through one complete cycle from an eye open position, through an eye closed position and back to the open eye position, with the eye remaining in the eye open position for a greater period of time than in the eye closed position;
- (D) torsion spring means operatively secured to both said drive means and said driven means for developing torque therebetween, said torsion spring means accumulating a predetermined threshold quantity of such rotary motion and converting each accumulated predetermined threshold quantity of such rotary motion into intermittent, relatively rapid reciprocating motion of said driven means, said torsion spring means being wound by such rotary motion when such reciprocating motion is blocked and unwound by the conversion of such rotary motion to such reciprocating motion, said torsion spring means additionally including means for releasably blocking such reciprocating motion until a predetermined threshold quantity of such rotary motion is accumulated.
- 2. The doll of claim 1 additionally including safety means for precluding overwinding of said torsion spring means.
- 3. The doll of claim 1 wherein said doll is a talking doll having a movable mouth and a mouth-driving mechanism for moving the mouth in general coordination with the talking of the doll, said mouth-driving mechanism being driven by said motion providing means.
- 4. A doll with an eyeblink mechanism, comprising:
- (A) an eye with a reciprocatable eyelid;
- (B) rotary disk means;
- (C) drive means for intermittently slowly rotating said rotary disk means in a given direction;
- (D) rotatable crank disk means for intermittently relatively rapidly reciprocating said eyelid when said crank disk means rotates, thereby to blink said eye;
- (D) fixedly disposed stop means engageable with said crank disk means for normally precluding rotation of said crank disk means;
- (E) biasing means biasing one of said stop means and said crank disk means into engagement with the other;
- (F) torsion spring means secured to both said rotary disk and said crank disk means for developing torque therebetween and causing relatively rapid rotation of said crank disk means in a given direction when the engagement of said stop means and said crank disk means is released; and
- (G) means for overcoming said biasing means once per revolution of said rotary disk means, thereby to release the engagement between said stop means and said crank disk means and thus permit rotation of said crank disk means and blinking said eye once per revolution of said rotary disk means.
- 5. The doll of claim 4 additionally including a safety mechanism for precluding overwinding of said torsion spring means.
- 6. The doll of claim 5 wherein said safety mechanism includes a soft connection between said crank disk means and said eyelid which enables rotation of said crank disk means without reciprocating said eyelid, and means for causing a full rotation of said crank disk means at least once per full rotation of said rotary disk means regardless of whether or not rotation of said crank disk means reciprocates said eyelid.
- 7. A talking doll with an eyeblink mechanism, comprising:
- (A) an eye with a reciprocatable eyelid;
- (B) rotary disk means;
- (C) drive means for intermittently slowly rotating said rotary disk means in a given direction;
- (D) rotatable crank disk means for intermittently relatively rapidly reciprocating said eyelid when said crank disk means rotates, thereby to blink said eye;
- (D) fixedly disposed stop means engageable with said crank disk means for normally precluding rotation of said crank disk means;
- (E) biasing means biasing one of said stop means and said crank disk means into engagement with the other;
- (F) torsion spring means secured to both said rotary disk and said crank disk means for developing torque therebetween and causing relatively rapid rotation of said crank disk means in a given direction when the engagement of said stop means and said crank disk means is released;
- (G) means for overcoming said biasing means once per revolution of said rotary disk means, thereby to release the engagement between said stop means and said crank disk means and thus permit rotation of said crank disk means and blinking said eye once per revolution of said rotary disk means; and
- (H) safety mechanism means for precluding overwinding of said torsion spring means, said safety mechanism means including a soft connection between said crank disk means and said eyelid which enables rotation of said crank disk means without reciprocating said eyelid, and means for causing a full rotation of said crank disk means at least once per full rotation of said rotary disk means regardless of whether or not rotation of said crank disk means reciprocates said eyelid.
- 8. The doll of claim 7 wherein said doll is a talking doll including a movable mouth, and said drive means also moves said mouth in general coordination with the talking.
- 9. The doll of claim 7 including a head, a body, and a neck physically connecting said head and body together while permitting limited relative rotational movement thereof, said neck including a neck switch responsive to a predetermined relative movement of said head and said body.
