Abstract: A remote-control doll assembly in which a high-frequency sound signal produced by squeezing a toy baby bottle actuates an internal motor to raise the arms of the doll and actuates an internal voice mechanism to simulate a crying sound. Insertion of the nipple of the bottle into the mouth of the doll opens a switch to interrupt the crying sound. In an alternative embodiment, a radio signal is used as a control signal. In another modification of the invention, a pressure-sensitive rattle is used to produce the control signal.

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.

Abstract: A gass-filled doll having articulated limb joints in which each of the individual torso and limb members is made up of a soft gas impervious skin filled with gas under superatmospheric pressure and the skin of each of which limb members at a limb joint location is formed with a recess for receiving a joint-forming element and in which each skin recess of the limb members is formed with an opening for admitting air to the member and for receiving a sealing element over which the joint forming element is secured after the member has been pressurized. In one embodiment of the invention the member is cooled with the skin recess open, a plug is cemented in the opening while the member is cool, the member is allowed to come to room temperature and the joint forming element is cemented in place over the plug.

Abstract: A walking simulating apparatus for a doll having legs pivotally mounted on the doll's torso for movement around respective axes extending at an acute angle to the vertical axis of the torso in which a pair of oppositely laterally extending arms carried by a pivot extending in the general direction of the torso vertical axis and resiliently urged into engagement with frusto-conical interior surfaces formed on the leg flange inserts carry detents adapted to engage first recesses in the leg flange insert surfaces to provide a releasable driving connection between the legs between limit positions determined by a third arm mounted for movement with the driving arms and extending generally perpendicularly thereto between the leg flanges so as to engage the flange inserts respectively at the limit positions corresponding to the limits of a stride of the doll.
