Abstract
Abstract A heartbeat simulator for a toy doll or the like comprises a resilient, relatively soft rubber diaphragm supported at its edges in a housing and formed with curved surface portions to provide a popping movement between an equilibrium position and a displaced position. A motor is periodically energized to displace the diaphragm by winding a cord attached at one end to the motor shaft and at the other end to the diaphragm and is immediately thereafter de-energized to permit the diaphragm to unwind the cord and return to its equilibrium position. A connecting tube acoustically couples the diaphragm to the mouth of the toy doll to produce a simultaneous breathing sound.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
196 words
In a doll, a heartbeat simulator comprising a diaphragm of resilient material, means mounting said diaphragm in said doll for movement between an equilibrium position and a displaced position, the construction and arrangement of said diaphragm being such as to provide a popping sound in the course of its movement both from said equilibrium position to said displaced position and from said displaced position back to said equilibrium position, and means for applying a force to said diaphragm in such a direction and for a sufficient period of time to move said diaphragm to said displaced position and then removing said force to permit the diaphragm to return to its equilibrium position under the action of the resilience of said resilient material, the relationship between said force applying means and the resilience of said material being such that said diaphragm moves more rapidly from one of said positions to the other than from said other position to the one whereby the sound produced in the course of one cycle of movement of said diaphragm closely resembles a human heartbeat sound, said force applying means applying said force at periodic intervals approximating those of a human heartbeat.
Claim 2
Dependent Claim
196 words
In a doll, a heartbeat simulator comprising a diaphragm of resilient material, means mounting said diaphragm in said doll for movement between an equilibrium position and a displaced position, the construction and arrangement of said diaphragm being such as to provide a popping sound in the course of its movement both from said equilibrium position to said displaced position and from said displaced position back to said equilibrium position, and means for applying a force to said diaphragm in such a direction and for a sufficient period of time to move said diaphragm to said displaced position and then removing said force to permit the diaphragm to return to its equilibrium position under the action of the resilience of said resilient material, the relationship between said force applying means and the resilience of said material being such that said diaphragm moves more rapidly from one of said positions to the other than from said other position to the one whereby the sound produced in the course of one cycle of movement of said diaphragm closely resembles a human heartbeat sound, said force applying means applying said force at periodic intervals approximating those of a human heartbeat.
Claim 3
Dependent Claim
21 words
A simulator as in claim 1 in which said mounting means secures the edge of said diaphragm in a fixed position.
Claim 4
Dependent Claim
17 words
A simulator as in claim 1 in which said diaphragm has a durometer hardness of approximately 45.
Claim 5
Dependent Claim
57 words
A simulator as in claim 1 in which said force applying means comprises a rotary motor, a cord having one end attached to said diaphragm and the other end attached to the shaft of said motor, and means for periodically energizing said motor to wind the cord on said shaft and pull said diaphragm toward said motor.
Claim 6
Dependent Claim
30 words
A simulator as in claim 1 in which said diaphragm offers a decreasing resilient restoring force over a portion of its movement from said equilibrium position to said displaced position.
Claim 7
Dependent Claim
14 words
A simulator as in claim 1 in which said diaphragm has a nonplanar surface.
Claim 8
Dependent Claim
14 words
A simulator as in claim 1 in which said diaphragm has curved surface portions.
Claim 9
Dependent Claim
17 words
A simulator as in claim 1 in which said diaphragm has a radially symmetric circumferentially corrugated surface.
Claim 10
Dependent Claim
45 words
A heartbeat simulator as in claim 1 in which said diaphragm has a portion with a curved cross-sectional shape, said portion reversing its curvature in the course of movement of said diaphragm from said equilibrium position to said displaced position to produce said popping sound.
Claim 11
Dependent Claim
24 words
A simulator as in claim 1 in which said mounting means includes a housing forming a closed cavity enclosing one side of said diaphragm.
Claim 12
Dependent Claim
44 words
A simulator as in claim 10 in which said doll is formed with an opening at the mouth, said simulator comprising means for providing an air passage through the interior of said doll between the interior of said closed cavity and said mouth opening.
Claim 13
Dependent Claim
19 words
A simulator as in claim 11 in which said means for providing an air passage comprises a hollow tube.
Claim 14
Dependent Claim
22 words
A simulator as in claim 1 in which said doll comprises a skin layer, said diaphragm being recessed from said skin layer.
Claim 15
Dependent Claim
19 words
A simulator as in claim 13, further comprising a foam layer disposed between said diaphragm and said skin layer.
Claim 16
Dependent Claim
21 words
A simulator as in claim 13, further comprising means for mechanically coupling the movement of said diaphragm to said skin layer.
