Animated doll
First Claim
1. An animated doll having a head, torso and limbs, the doll further comprising:
- an animation mechanism for moving a plurality of limbs of the doll, said animation mechanism being housed in a casing adapted to be received within the torso of the doll and comprising;
an electric motor;
a plurality of pivotal members, each pivotal member being adapted to extend into one of said plurality of movable limbs of the doll to transmit a pivoting movement to the limb;
a cam means comprising a plurality of lever arms each connected to one of said pivotal members and having a cam follower that engages with a wheel cam operatively coupled to said electric motor, a plane of rotation of said wheel cam and a plane of pivoting movement of said lever arms being substantially parallel to a plane that passes through both said torso and said plurality of limbs of the doll, wherein said cam means is adapted to produce an unco-ordinated movement of said plurality of limbs of the doll which appears to be less mechanical in nature and more life-like; and
,a sensing means for detecting an external stimulus applied to the doll and for activating the animation mechanism when said external stimulus is detected whereby, in use, the doll appears to respond to the external stimulus by moving said plurality of limbs.

Abstract
An animated doll having a head, torso, and limbs is provided with an animation mechanism for moving the limbs. The animation mechanism is housed in the torso and includes an electric motor, a cam wheel rotated by the motor, and a plurality of lever arms engaged with the cam wheel and pivotal as the wheel rotates. A plurality of pivotal members are provided, each extending into a respective limb. Each lever arm is engaged with a respective pivotal member to produce movement of the limbs in response to operation of the motor. The plane of rotation of the cam wheel and the plane of pivoting movement of the lever arms is parallel to the plane which passes through the torso and limbs. A switch may be provided to provide electric power to the motor. The switch may be a magnetically actuated switch located at the mouth of the doll; and a magnet to actuate the switch may be provided on a simulated feeding bottle or on clothing of a user. The doll may produce sounds such as crying, sucking, or a heart beat.
