Abstract

ABSTRACT OF THE DISCLOSURE
A mechanism for dolls which allows for crying, movement of the lips and swivelling of the eyeballs. The mechanism includes a control circuit and timing element which is connected to a switch placed in the mouth of the doll, a magnetic field detector placed in the proximity of the mouth, a voice apparatus, and a motor attached to a mechanism for moving the lips and eyes.
The latter mechanism consists of an eccentrically mounted shaft which is attached to one end of a spring having its other end connected to a piece that ends in the shape of an arrow-head connected to the doll face in the proximity of the mouth of the doll. A pacifier inserted in the mouth of the doll, opens the switch to maintain inactive all the devices. If the pacifier is removed, the voice device is activated. A bottle having a magnetic element can be inserted into the mouth, and operates the magnetic field detector to start the motor and operate the lips and the eyes. Upon removal of the bottle the whole mechanism stops; the timing element starts and after an interval the voice device reactivates.

MECHANISM FOR THE CRYING AND SUCKING MOTION OF DOLLS
OBJECT_OF THE INVENTION

The present invention provides a mechanism for dolls which cry and suck and in which a crying sound, produced from a voice device, is initiated when a pacifier is removed from the mouth of the doll. When a bottle is placed in the mouth of the doll a device for moving the lips becomes activated, simulating the action of sucking on the bottle and at the same time the eyes of the doll start moving. When the bottle is removed from the mouth, the sucking device ceases operation; also a timing device is started and after a certain time, the voice device starts again producing the crying effect. When again the :
pacifier is placed in the mouth of the doll, both devices stop and the voice device gets set for a new cycle.
' `~

BACKGROUND OF THE INVENTION

In the past, many mechanisms have been incorporated in dolls to achieve different functional characteristics.

~ For example, Spanish Patent No. 8700752 claims a device for the combined movement of the mouth and eyes of dolls.

There are also dolls that incorporate voice devices which i ~

3 ~

allow for crying, laughter, etc. -~

However, hitherto there has not been known any doll that provides a combination of eye movement, crying and lip movement by devices which are as simple and economical as ;
is desirable.

SUMMAIIY OF TEE INVENTION ~':

The invention provides a doll having a crying and sucking mechanism in which a voice device and a lip moving device ~;
are combined with an eye movement mechanism as well as a timing control circuit.

The timing control circuit governs the functioning of the system, and includes a switch located in the mouth of the doll, the mouth having an orifice through which a -pacifier is inserted to operate the switch. ~` ;

The timing circuit control is connected to the voice device as well as to a motor that provides the eye and lip movement.
,, ~ , .....

Furthermore~ the timing control circuit is connected to a magnetic sensor, located close to the mouth of the doll. -~
. ........

~, ~ 2 ~
, ~

The arrangement is such that when the pacifier is placed through its mouth orifice into the switch located in the mouth of the doll, the control circuit maintains inactive the voice device and the motor and therefore all mechanisms remain inactive.

Once the pacifier is removed from the switch inside the mouth of the doll, the timing control circuit activates the voice device, as a consequence of which the doll :
starts crying. If, in this situation, a bottle is introduced in the mouth, this bottle containing a magnetic element in its nipple, the magnetic sensor detects the presence of the magnetic element, and the timing control circuit activates the motor, which in turn starts the lip moving device and the lateral movement of ~ :
the eyes, simulating a child's movements in drinking the `:
bottle.

If the bottle is then removed from the mouth of the doll, the magnetic sensor detects the absence of the magnetic element, and the timing circuit control deactivates the 20 lip and eye movement devices; and, after a predetermined time has elapsed, the control circuit activates the voice device to produce the crying sound.

If the pacifier is inserted again into the switch located --` 2 ~ 3 ~ :

in the mouth, this situation is detected by the switch connected to the control circuit, which deactivates all circuits, and the doll is reset for a new cycle.

The lip moving device consists of a vertical --~
eccentrically mounted shaft connected to the motor by gears, this shaft holding one end of a spring which has its other end attached to a connecting piece that ends in :
shape of an arrow head, this arrow head being anchored in : the proximity of the lips of the doll, in such a way that when the motor operates, circular movement of the eccentric shaft causes the displacement of the arrow head shaped piece, and therefore causes movement of the ~.
lips of the doll.
; ` ''~
The eccentric shaft passes through a slot in an actuator ;~
connected to the eyes so that when the eccentric shaft ~ :;
rotates, a transverse displacement of the actuator occurs ~
and this transverse movement is transmitted to the eyes. ~ :
This movement provides a lateral displacement of the eyes --in a continuous manner from one side to the other, until the motor is stopped. - .

DESCRIPTION OF A PREFERRED EMBODIMENT OF THE INVENTION .

Referring to the drawings, the doll has a head H of pliable, rubber-like molded material, terminating in an ;
annular neck which is a snap fit on an annular groove 22 surrounding a neck piece N; this neck piece also has a lower groove 22a which receives the neck opening of a body portion (not shown). ~ ;

A timing control circuit 1 is connected to a switch 2 placed in the mouth of the doll 3 and accessible through an orifice 4. In addition, the timing control circuit 1 is connected to a magnetic field detector 5 which is located in the proximity of the mouth 3 of the doll.

The timing control circuit 1 is also connected to a ~-motor 6 placed in a box 7 which through gears drives a cylindrical piece 8, passing through part N, and from piece 8 extends a shaft 9 parallel to the axis of piece 8 but eccentric thereto, and rotatable around that axis.
Shaft 9 holds one end of spring 10 which has its other end attached to a piece 11 that ends in the shape of an ;~ v arrow head 12 having a point which is an interference fit in a cavity formed in an internal protrusion 3a close to ~-and below the mouth 3 of the doll.

,' ' ,. ',.
.','.,."'~";',-~ ~3~31 The upper part of shaft 9 passes through a slot 13 in an actuator having a base piece 14a slidably held by claws 14b on a support 16 which includes cylindrical extensions 16a connected to the rear of sockets 16b which contain eyeballs 15.

The eyeballs 15 are mounted in sockets 16b with allowance for lateral swivelling, and swivelling movement is controlled by rods 17 passing from the eyeballs, through slots in support 16, and tiltably connected to `~` i the actuator base piece 14a. Thus, lateral displacement `~
of the actuator 14 caused by movement of shaft 9 causes swivelling movement of the eyeballs 15.

The doll also incorporates a voice device 18 that incorporates a motor 19 and the diaphragm 20, as well as a needle record (i.e. phonographic device), of such type that when the motor 19 is running the sound recorded can be heard which in this case is the sound of crying of a doll.
: `~
T~e power supply of all systems of the invention is made through the batteries 21.

The operation oE the invention will now be described.

~. J23~3~

The pacifier 23 has a switch operating shaft 24 which is introduced into the orifice 4 to open the switch 2 in the mouth 3 of the doll whereupon the timing control circuit 1 cuts the power of the motors 6 and 19, deactivating the doll circuits.
.:

If the pacifier 23 is removed from the mouth of the doll and therefore from the switch 2, allowing this switch to elose, this situation is detected by the timing control switch, which activates the motor 19 of the voice device to produce a erying sound. `~
' ,,. ,~;, If, after that, a bottle 25 having a nipple 26 which ineorporates internally a magnetie element (Fig. 4) is plaeed in the mouth, the aetion of the magnetie element on the magnetie field deteetor aetivates the timing ~``
eontrol eireuit to start the motor 6. This causes the eecentrie shaft 9 to rotate so that the foree transmitted ;~
by the spxing 10 produees a displaeement of the arrow `~
head shaped pieee 11 and accordingly displaees protrusion 3a by which movement of the lips of the doll is produeed ~-bo simulate sueking on the bottle. Simultaneously, motor 19 is deaetivated so that the erying sound eeases. ;: ~
:.- ' ' ..:.`, If, then, the bottle 25 is removed from the mouth of the ~, i3 ~ 3 ~

g doll, the magnetic field detector 5 sends a signal to the timing control circuit 1 whlch deactivates the motor 6, so that the movement of the lips and eyes stops.
Also the timing control circuit 1 is also activated so that once a predetermined time is up, the motor 19 gets activated again and the doll starts crying again.

Therefore, the motor 19 whi.ch produces the crying of the doll is deactivated, as long as the pacifier 23 is present into the switch 2, or if the pacifier is :
di.sconnected from the switch 2 and the bottle 25 is introd~ced to the proximity of the mouth 3. If either pacifier cr bottle are removed from the mouth of th.e doll, at that instant the timing starts, and when a time period has elapsed, the crying mechanism is act.ivated aga~n by starting of the motor 19.

Therefore each time the motor 6 is activated, the lateral swivelling movement of the eyes 15 is produced ~ ~.
by the action of the transversal displacement of t.he eccentric shaft 9. It is important to remember ~.hat the ~ :
motor 6 functions as long as the bottle 25 is introduced sufficiently near to the mouth 3 of the doll to activate switch 5.
, The timing circui.t is also arranged to autcmatically ~ ~;

2 0 2 3 ~ ~ 1 discontinue the crying sound, after a predetermlned period, if the doll is left unattended. The circuit is arranged to be re-activated when the pacifier is inserted into the mouth and subsequently removed.

The record or phonograph type device may be replaced by a so-called "speech chip", specifically a CMOS LSl (large scale integrated) speech chip, such as are available for example from Eletronic Speech Systems, Inc. of Califor- ;~
nia, U.S.A., and sold under the trade-mark "SOUND MAGI-CIANN. A suitable chip has the trade designation ES
3016, which is a 20-pin chip with 1638~ bytes of onboard ROM (Read Only Memory) and a PLA (Programmable Logic Array). In addition to the crying sound described, such ~:
a chip may be arranged to make a sucking sound when the ;~
mouth and eye movements are operative, and to make a ~ ``
cooing sound for a few seconds after a nipple has been removed and before the crying starts.
