Abstract
Abstract An animated toy doll which simulates a baby falling asleep is provided. Initially, the doll sits upright. A mechanical internal mechanism is provided for tilting or nodding the head forward, and then tilting the entire torso rearward to a final reclined sleeping position. The motions of the doll are triggered by squeezing one of the feet of the doll. Motion of the internal mechanism is dampened by a thick silicone gel to ensure slow and smooth movement of the mechanism to achieve a realistic, graceful animation of the doll. No electrical device or motor is required.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
196 words
A toy doll comprising: a torso with a pair of legs pivotally mounted to a bottom portion of said torso; a head pivotally mounted to a top of said torso for pivoting between an extended position wherein said head extends upwardly from said torso, and a forward position wherein said head is tilted forward with respect to said torso, with a chin of said head proximate a chest of said torso; and automatic means for repositioning said doll from a sitting position wherein said doll sits upright with the legs of the doll extending forward from the torso for supporting the torso upright on a supporting surface to a reclined position wherein said torso and said legs lie supine on said supporting surface, including first triggering means, operable only while said torso is in said upright position and said head is in said extended position, for triggering said forward head pivot means to pivot said head to said forward position, and second triggering means, operable only while said torso is in said upright position and responding as said head reaches said forward position, triggering said torso pivot means to pivot said torso to said reclined position.
Claim 2
Dependent Claim
196 words
A toy doll comprising: a torso with a pair of legs pivotally mounted to a bottom portion of said torso; a head pivotally mounted to a top of said torso for pivoting between an extended position wherein said head extends upwardly from said torso, and a forward position wherein said head is tilted forward with respect to said torso, with a chin of said head proximate a chest of said torso; and automatic means for repositioning said doll from a sitting position wherein said doll sits upright with the legs of the doll extending forward from the torso for supporting the torso upright on a supporting surface to a reclined position wherein said torso and said legs lie supine on said supporting surface, including first triggering means, operable only while said torso is in said upright position and said head is in said extended position, for triggering said forward head pivot means to pivot said head to said forward position, and second triggering means, operable only while said torso is in said upright position and responding as said head reaches said forward position, triggering said torso pivot means to pivot said torso to said reclined position.
Claim 3
Dependent Claim

The toy doll of claim 1, wherein said head includes biasing means for biasing movement of said head from said extended position to said forward position while said torso is positioned upright, retaining means for holding said head in said extended position while said torso is positioned upright, and release means for releasing said retaining means to allow said biasing means to pivot said head to said forward position.
Claim 4
Dependent Claim
58 words
The toy doll of claim 2, wherein said head pivots about a pivot axis, and a center of gravity of said head is positioned forward from said axis while said head is in said extended position and said torso is in said upright position such that said head is biased by gravity to pivot to the forward position.
Claim 5
Dependent Claim
28 words
The toy doll of claim 1, wherein said doll further includes automatic rearward head pivot means for pivoting said head from said forward position to said extended position.
Claim 6
Dependent Claim
