Abstract: This invention refers to a perfected roller-skating doll of the type that alternately moves its legs and head in sync, and which has two speeds that alternate while the doll is in operation. The system is based on a gear mechanism worked by a motor which includes features that allow a cog wheel to axially move so that it can engage alternately with one or another pinion, of different sizes, in order to achieve the two speeds. The mechanism is complemented with a drum which is made to revolve in order to transmit movement to the legs. The drum in question is provided with a winding, ring-shaped groove inside which a pin emerging from each corresponding leg freely moves. This pin joins each corresponding to the mechanism assembly and, in particular, to the drum groove. On the shaft on which the drum-affecting pinion is mounted, there is a socket integral with the pinion, and which houses a widened section of the aforementioned shaft.

Abstract: A roller-skating doll includes a gear mechanism operated by an electric motor. The gear mechanism provides a revolving movement to a drum having a winding, ring-shaped groove containing two pins belonging to levers that actuate the legs of the doll. These levers are linked to two other levers, articulated in the middle, which convey the movement to the arms of the doll. There is also an eccentric on the outlet shaft of the drum in order to translate the movement to the head of the doll. The winding groove provided in the drum ensures that the movements of the legs, arms and head of the doll are synchronized. In addition, there is a device that causes the mechanism to stop for a moment and then to start again, as well as a clutch which allows the motor to idle in the event the doll would fall over if blocked by an obstacle.

Abstract: The doll of the invention incorporates a mechanism and electric circuit that, originating from a general activation motor which moves a series of engagements, brings about a correlative series of movements which cause the doll to crawl and give out a message and, subsequently, to stop crawling and raise the trunk of its body and head, to turn its head and give out a new message. These movements are based on the eccentric operating several elements related to the arms, legs and head. Likewise, the emission of the messages is based on parts which are independent but combined electrically and mechanically with the general mechanism in order that, altogether, they achieve a succession of movements which are repeated constantly until a general switch is activated by means of, for example, a dummy, or by means of a ball switch activated automatically when the doll is picked up and put upright.

Abstract: This invention relates to improvements in the manufacture of devices applicable to dolls that simulate physiological functions. On exerting pressure on a tank of water situated in the interior of the doll, a tube which commences in the interior of the tank below the level of the water, conducts a small flow of the said water towards the interior of the mouth of the doll and surrounding areas, although in a position in the mouth in front of a second tube which commences in the interior of the tank and in the area not occupied by water, with the purpose that the same pressure should originate a current of air which, on emerging adjacent to the first tube and also in the interior of the mouth, causes the creation of small bubbles and the outlet of small amounts of water that simulate the dribbling of the doll and because a third tube for filling the tank also commences in the interior of the mouth of the doll so that on placing a bottle of water into the mouth the filling of the tank is produced.
