FR2568786A2 - MECHANISM FOR CONTROLLING THE MOVEMENT OF MEMBERS OF A DOLL - Google Patents

Abstract

THE PRESENT INVENTION RELATES TO A MECHANISM FOR CONTROLLING THE MOVEMENT OF THE MEMBERS OF A DOLL. THIS MECHANISM IS CHARACTERIZED IN THAT IT INCLUDES, IN A RIGID BOX 1, A ROTARY SWITCH WITH COUNTERWEIGHT WHICH OPENS OR CLOSES THE ELECTRICAL CIRCUIT OF A MICROMOTOR DEPENDING ON THE LYING OR STANDING POSITION OF THE DOLL, THIS MICROMOTOR OPERATING THE LEGS 7. THE DOLL.

Description

The present invention relates to an addition of

  to the invention - the subject of the application

  principal, which concerns a mechanism for controlling the movement

  members of a doll. This mechanism is

  Characterized in that it comprises means for imparting to the four limbs of a doll movements such that the movements of an arm and those of a leg on the same side are out of phase with each other and that those of a m-member on the right side alternate with those of the corresponding member

located on the left side.

  We already know the mechanisms of dolls operating the legs of a doll, but once in action, when the

  doll is lying, the legs continue to be operated.

  This does not correspond to what happens to beings

that dolls imitate.

  The invention according to the present application constitutes a

  improvement in the control mechanisms of the

members of the dolls.

  The proposed invention overcomes the disadvantages of known dolls to date because it is characterized in that the mechanism comprises, in a rigid box, a counterweight rotary switch that opens or closes the

  circuit of a micromotor according to the

  the doll, this micromotor actuating the

legs of the doll.

  It has also been found that it is possible to improve

  to improve and perfect such mechanisms by obtaining

  reciprocating the lower limbs of the doll as if it were walking. The mechanism in question serves at the same time as reinforcement and support to the body of the doll. This body is constituted outside of a fabric and is filled with a spongy material, which

  offers a double attraction because of the sensation of

  dear that it offers to the child who possesses it. The movements of the doll are improved because they are more real

  and the touch is softer and pleasant.

  An embodiment of the present invention will be described hereinafter by way of nonlimiting example, with reference to the appended drawing in which:

  FIG. 1 is a front view of the mechanism

  according to the present addition, especially in cross section.

  Figure 2 shows the same mechanism of the

  1, of profit, in longitudinal section and FIG. 3 is a view of profit of a doll assembly provided with the improved mechanism according to the invention

  proposed, also in longitudinal section.

  The mechanism according to the drawing comprises a rigid box 1, in which is incorporated an electric battery holder la, in particular in the rear part corresponding to the

  back of the doll according to the invention.

  In this casing 1 is also housed a reducer 2 composed of an electric micromotor which actuates a gear train to increase the speed of rotation of the motor and bring it to the desired rotational speed according to the needs that arise. An output shaft of the gearbox 2 comes out of both sides of the housing 1 and carries,

  coupled with its two extreme parts, eccentric cams

  placed in reciprocal positions in diametrically

  Zement opposite. Eccentric cams 3 are housed in

  orifices carried by connecting rods 4. Eccentric cams

  3 to the rods 4, by their rotation, a de-

  Reciprocating placement in longitudinal direction, inside the casing 1. The connecting rods 4 carry, at one of their extreme parts, a pivot 5 rotating about an axis Sa and thus maintaining a gyratory movement. The connecting rod 4 having

  its axis of rotation in Sa, when your eccentric cam turns

  ne, this rod 4 moves up and down its end opposite the end portion 5a, from top to bottom. It prints at the same time a displacement on the split lever 6 carrying an elongated slot and makes you turn about its axis

according to the desired movement.

  The slotted lever 6 extends, at its end opposite its axis of rotation and towards the outside of the casing 1, by a part of smaller section, strangled, 6a, in order to provide protection against a possible rupture of the internal levers of the mechanism. This extension of the slotted lever 6 being of transverse dimension more

  reduced and made from a flexible and elastic material

  that, whose bending capacity is greater than the resistance that can oppose the movement of any component part of the mechanism, it offers security against any possibility of rupture. The doll can cope with any

  external occasion of deterioration which could

Senter.

  The lower extreme part of the foreign extension

  gZé 6a is secured to a stepped enlargement, frustoconical shape that can be housed inside a doll leg 7. The doll leg has, in the front portion of its upper stump, a perforation in which accommodate the mentioned cones, ensuring

  in the two rooms the association by the bleachers of this

truncated cone.

  A rotary switch is housed inside the doll. This counterweight switch opens and closes the electrical circuit of the motor, according to its vertical position or

  horizontal, including standing or lying, of the doll.

  When putting the doll upright, for example by lifting it by an arm (Figure 3), the switch closes the

  electrical circuit and make it work.

  The doll is not able to stand in equi-

  free on his legs, it must be maintained and raised

  all the time we play with her.

  When the doll falls or is lying down, the

  rotary switch cuts the circuit due to its counterweight

and the doll stops.
