A wheel with eccentric studs mounts and drives each rod to impart a reciprocating displacement to the lips, such displacements being staggered, to simulate lip movement as in talking. An electric motor drives the wheel. A circuit breaker may be positioned in the head near an opening at the mouth so that an object inserted therein will turn off the electric motor.
8 Claims, 3 Drawing Figures HEAD WITH LIPS MOVABLE BY RODS ECCENTRICALLY MOUNTED TO A WHEEL The present invention relates to improvements to dolls and similar toy figurines, of the type comprising a head provided with a mouth formed of two superimposed lips.
It has already been proposed to include in dolls of this type a suitable mechanism to impart an alternating motion to one of the lips so as to simulate speaking, but known constructions are complex and expensive, without realistically reproducing the emission of speech by a child.
The object of the present invention is to overcome the above-mentioned disadvantage and allow produc- 'tion of a simple and robust mechanism which will perfectly simulate both speech and sucking movements.
The doll or toy figurine of the invention is characterised by the fact that with each lip is associated an inde pendent operating organ linked to a suitable drive mechanism for imparting to the said organ a reciprocating, axial displacement which causes pulling of the corresponding lip in a direction substantially perpendicular to the vertical plane of the face of the figurine, the movements of the two lips being staggered relative to each other, the better to simulate reality.
In accordance with a preferredembodiment of the invention, each operating organ consists of a rod shaped like a piston-rod, the head of which is engaged on an eccentric stud provided on the lateral surface of a toothed-wheel which controls the two operating organs, the said wheelbeing rotated continuously. It is advantageous to impart to the upper lip an alternating displacement of lesser amplitude than to the lower lip; this can easily be effected by providing a lesser eccentricity for the corresponding stud of the toothed wheel than for the opposed stud, the two studs being angularly spaced by approximately 90 on the two surfaces of the said wheel.
In order that the invention may be well understood there will now be described an embodiment thereof, given by way of example only, reference being had to the accompanying drawing in which:
FIG. 1 is a partial axial section of the head of a doll in accordance with the invention,
FIG. 2 is a horizontal section of larger scale along the line ll ll (FIG. I), and
FIG. 3 is a schematic view showing the relative positions of the two lateral studs of the toothed drive wheel.
In FIG. 1 reference 1 indicates the head of a doll made of semi-rigid, elastically deformable synthetic material. The base 2 of circular cross-section of head 1 is rotatably engaged in the upper, open portion 3 of the body proper of the doll. Head 1 is so shaped as to reproduce the face of a baby and includes a mouth formed by two superimposed lips 4 and 5, below a nose 6.
In order to move each of the lips 4 and 5 a drive mechanism is employed, as follows: To each of lips 4 and 5 is attached, for example by simple gluing inside an open transversal perforation, the end of an operating rod 7 and 8 respectively, of semi-rigid synthetic material, the opposite end 7a or 8a of which is annular. As shown in FIG. 2, ends or heads 7a and 8a are engaged on two cylindrical studs 9a and 9b provided on the opposed lateral surfaces of a toothed wheel 9. It will be noticed (FIGJ3) that the radii of wheel 9 which pass through the points of greatest eccentricity of these two studs are radially spaced'by an angle alpha of approximately and that the radius of eccentricity of stud 9a for control of rod 7 and lower lip 4 is greater than the radius of eccentricity of the opposed stud 9!).
Beyond studs 9a and 91) wheel 9 is rigidly connected to two cylindrical gudgeon pins 90 aligned with the centre of the said wheel so as to form the rotational axis of the latter. These gudgeon pins 9c are engaged in housings provided in a casing formed of two parts lflof synthetic, moulded material,joined together at I] and 12. Wheel 9 engages with a worm l3fixed on the vertical spindle of an electric motor 14 held in the cylindrical base of casing 10 10. This base is engaged in the upper portion of a fixing socket 15 provided with two elastically deformable tongues 16 which snap into depressions 10a in the casing. Socket 15, which is axially split, is introduced with a force fit into base 2 of head 1, being angularly immobilised by a stud 2a of the lat ter, which stud 2a'is engaged between the lateral walls of a gap which is provided in the periphery of the socket 15 in such manner that the stud 2a is immobilized.
The operation of the assembly described above will be easily understood. When a voltage is placed across motor 14, toothed wheel 9 is rotated at a relatively low speed by worm 13: because of their eccentricity relative to gudgeon pins 90, studs 9a and 9b cause axial displacement of rods 7 and 8 which exercise a pulling effect on each of lips 4 and 5, it being noted that a movement of greater amplitude is thus imparted to the lower lip 4. The elasticity of the synthetic material of head 1 causes return of the lips to a rest position when rods 7 and 8 move towards the mouth of the figurine. To avoid any deformation of the whole of the face of this figurine, the parts 10 which form the casing are rigidly connected to a frontal extension 17 FIG. 1 which is firmly applied to the inside of nose 6.
Because of the angle of pull and the lag of the lip movement, the lips slide relative to each other, strikingly simulating the emission of speech or the attitude of a suckling baby. It will be noticed that when an object is introduced into opening 18 formed for this purpose between lips 4 and 5, the said object, which may be a dummy, a toy feeding-bottle, etc. is itself moved by the above-mentioned lips in an alternating, rocking motion, even when the doll is in the horizontal, lying-down position.
To the assembly described above may be added an electric circuit-breaker or commutator controlled by the object introduced through opening 18. As shown, such a circuit breaker may include two metallic strips 19 and 20, fixed laterally against casing 10 l0; strip 19 being rigidly connected to a stud 19a which acts as a contact and keeps strips 19 and 20 at a sufficient spacing to allow passage of rods 7 and 8. Wires 2] and 22, attached to strips 19 and 20, permit connection of the circuit breaker into the supply circuit of any electric motor; this may either be motor 14 or the motor associated with a mechanism such as 23 housed in the body of the doll (sound reproduction apparatus, movement mechanism associated with the arms or legs, etc.
1. A doll or similar toy figurine, comprising a hollow head of elastically deformable material shaped to reproduce a face including a mouth formed by two superimposed lips disposed below a nose, a casing fixedly mounted within the hollow head, a drive mechanism for moving said lips mounted within said casing, said drive mechanism including a wheel journaled in said casing, cylindrical studs eccentrically mounted on opposed lateral surfaces of said wheel; operating rods for the lips, respectively, each rod having one end attached to its related lip and the other end having an annular head rotatably mounted on a related one of said studs, said drive mechanism including means for driving said wheel; whereby as the wheel is rotated each said rod will be displaced in a direction generally along its longitudinal axis to impart to the lips, respectively, a generally reciprocating motion which displaces the corresponding lips in a direction generally perpendicular to the vertical plane of the dolls face.
