Abstract:
This comprises a mechanical system ( 1 ) and a pneumatic system ( 3 ) that are interconnected to perform three phases. In the first one a walking mechanism is activated consisting of an oscillating plate ( 77 ) connected to the doll&#39;s legs. The second phase takes place when the doll is supplied with air and water through the mouth ( 43 ), connected by tubes ( 44 ) to a pneumatic accumulator ( 24 ) and an output valve ( 45 ) capable of being manually placed in an opened or closed position. During this phase, the doll repeatedly moves its hand towards its crotch, while it changes from walking to a restless movement, accomplished thanks to the alternating axial movement from a moveable toothed crown ( 12 ) and to the dissipation of energy in an arm clutch ( 29 ). The third phase consists in the ejection through the output valve ( 45 ) of a squirt of pressurized water, previously stored in the pneumatic accumulator.

Description:
FIELD OF THE INVENTION 
     The present invention refers to a doll which, having mechanical, electrical and pneumatic systems, simulates certain complex actions without its internal organs being affected by the use of water. 
     BACKGROUND OF THE INVENTION 
     Dolls that urinate after administering water to them through the mouth are well known. However, all embodiments fail in having a high risk of leakage from the internal storage water devices, which conflicts with the ever more frequent use of electrical and electronic devices. Another frequent problem is that making the flow of water which simulates the doll&#39;s urine to have a certain pressure demands the use of a second electric motor to pump the water to the exterior, which clearly complicates the product and makes it more expensive. 
     Document U.S. Pat. No. 3,839,819 describes a doll that urinates in which a container is used that is previously filled with water, associated to a double-effect, intake-output pump which must be manually activated by the user in an unrealistic way. 
     Document U.S. Pat. No. 4,115,948 describes a doll that urinates in which it is necessary to manually withdraw the water container from the inside of the doll once it is full, and then connect it again to the output conduct. 
     Document U.S. Pat. No. 4,160,338 uses a pneumatic accumulator, but it must be filled with air by means of a second bellows that is activated patting the doll&#39;s back, which involves the need of coordinating various operations (the feeding and the patting). 
     BRIEF SUMMARY OF THE INVENTION 
     One objective of the present invention is to have a doll in which the volume of water it can receive is small and automatically limited. 
     Another objective of the present invention is to have a doll in which the necessary pressure to simulate the action of urinating is automatically generated in the same operation of water intake. 
     And another objective of the present invention is to have a doll in which an alternative restless movement or walking movement can be obtained in a simple and economical way, using only one electrical motor. 
     To obtain the proposed objectives the doll of the invention comprises a mechanical system, an electronic system, and a pneumatic system. 
     The mechanical system starts with an electric motor that operates an already known conventional walking device, as well as an arm clutch that causes the flexing of the elbow in one of the doll&#39;s arms simulating that it is moving its hand to its crotch, when an excessive consumption of energy is produced by the walking mechanism, so it transmits a restless movement to the doll. The alternating of the walking movement and the restless movement is produced by the action of the alternating axial movement of a moveable toothed wheel caused by the encounter with a circular cam with an axially fixed toothed crown, both receiving the movement from a common gear with both crowns presenting a slightly different angular speed, since, although receiving their movement from the same gear, the number of teeth they present is different by one unit. 
     The pneumatic system starts at the doll&#39;s mouth and it consists of a series of tubes that join it to a pneumatic accumulator and to an output valve that simulates the doll&#39;s penis and which is opened or closed according to the manually determined geometric position. The pneumatic accumulator is united to a pneumatic clutch that activates or deactivates the previously described transmission of alternating movement for the articulation of the elbow, in such a way that the doll&#39;s restless movement, associated with the moving of the hand to its crotch, only occurs when the pneumatic accumulator has been loaded with water and air by means of a special baby-bottle. 
     The conventional electronic system consists of a battery box, a speaker to emit different sounds adequate to each of the doll&#39;s activity phases and the corresponding electronic control circuit to synchronize it with the mechanical movements.

     DETAILED DESCRIPTION OF THE INVENTION 
     As can be seen in FIGS. 1 and 9 the doll object of the invention has in its interior a mechanical system ( 1 ), an electronic system ( 2 ) and a pneumatic system ( 3 ). 
     The mechanical system consists of an electric motor ( 4 ) that transmits the movement from its drive pulley ( 5 ) by means of a belt ( 6 ) to a receptor pulley ( 7 ) connected to a shaft that has on one side a receptor pulley gear ( 8 ). On the receptor pulley gear ( 8 ) fits an alternating shaft crown ( 10 ) on the alternating shaft ( 11 ) of which can freely turn two toothed crowns ( 12 ) ( 13 ), whose number of teeth differ by one unit and that, having two opposing circular cams ( 14 ) ( 15 ) on its facing sides, they receive their movement from a long drive gear ( 16 ) connected to a drive gear crown ( 17 ) that fits into a an alternating shaft gear ( 18 ), that is likewise connected to the alternating shaft ( 11 ). In this way the moveable crown ( 12 ) and the fixed crown ( 13 ) freely turn on the alternating shaft ( 11 ) at slightly different speeds driven by the drive gear ( 16 ) in such a way that the moveable crown ( 12 ) is submitted to a large alternating period along the alternating shaft ( 11 ) itself, on which it freely turns depending on whether the opposing circular cams ( 14 ) ( 15 ) are facing each other or not. This axial movement on the alternating shaft ( 11 ) is accomplished against the action of an alternating shaft spring ( 19 ), that tends to bring both crowns ( 12 ) ( 13 ) nearer. 
     The movable crown ( 12 ) moves between two plans perpendicular to the alternating shaft ( 11 ), one of which coincides with that defined by a pneumatic clutch drive crown ( 20 ) connected to a pneumatic clutch drive gear ( 21 ) into which a pneumatic clutch receptor crown ( 22 ) fits at 90° when it is pushed by a pneumatic clutch sector ( 23 ), and that activated by a pneumatic accumulator ( 24 ) is articulated on a sector shaft ( 25 ) that has a fixed cube ( 26 ). A pneumatic clutch spring ( 27 ) that is supported on a pneumatic clutch output gear ( 28 ) and on the fixed cube ( 26 ) pushes both the pneumatic clutch receptor crown ( 22 ) and the pneumatic clutch output gear ( 28 ) upwards, maintaining the first item separated from the pneumatic clutch drive gear ( 21 ). 
     The mechanical system is completed with an arm clutch ( 29 ) (see FIGS. 1 and 3) consisting of an arm receptor crown ( 30 ) connected to an arm shaft ( 31 ) fitted permanently with the pneumatic clutch output gear ( 28 ). An arm coupling part ( 32 ) on which is mounted a flexible arm ( 33 ) can freely turn on the arm shaft ( 31 ) overcoming the produced friction against a friction washer that separates it from an interior bushing connected to the arm shaft ( 31 ). A second exterior bushing is mounted by pressure on the arm shaft ( 31 ) controlling the distance between both bushings ( 35 ) ( 36 ) in such a way that the arm coupling ( 32 ) and the friction washer ( 34 ) are locked between them. Thus, when the arm shaft ( 31 ) receives the movement from the arm receptor crown ( 30 ) and the pneumatic clutch output gear ( 28 ) draws the arm coupling ( 32 ) by friction until the coupling lever ( 38 ) connected to it hits against a butt end ( 39 ′) fixed to a coupling receptor part ( 39 ) on the doll&#39;s torso. 
     The conventional electronic system ( 2 ) consists of a basic electronic circuit ( 40 ) with an output speaker ( 41 ), which is all fed, as well as the electric motor ( 4 ) by means of a set of batteries ( 42 ) (see FIG.  9 ). 
     The pneumatic system ( 3 ) starts at the doll&#39;s mouth ( 43 ) which is united by tubes ( 44 ) to an accumulator ( 24 ) and an outlet valve ( 45 ). This is made up of a fixed interior conduct ( 46 ) with a central spherical area ( 47 ) on which an exterior body ( 48 ) can turn, also having a moveable interior conduct ( 49 ) that can be facing the fixed interior conduct ( 46 ) or not. On the moveable interior conduct ( 49 ) an elastic cylindrical body ( 50 ) is mounted, simulating an infant&#39;s penis. The pneumatic accumulator ( 24 ) consists of an elastic bellows ( 51 ) capable of expanding against the action of an accumulator spring ( 52 ), located between a bellows cover ( 53 ) and the accumulator cover ( 54 ) that closes an accumulator box ( 55 ). The bellows cover ( 53 ) prolongs to a bellows cover rod ( 56 ) that, sliding through the accumulator cover ( 54 ) articulately connects to a prolongation ( 57 ) on the pneumatic clutch sector ( 23 ). Notice that in FIG. 1 the sector prolongation ( 57 ) is represented cut off, in its two extreme positions, on the left, united to the rod ( 56 ) it is in the high position while on the right of the figure it is in a low position. 
     The operation of the device is as follows: 
     In a first phase, when a main switch ( 58 ) is closed the electric motor ( 4 ) is activated, which by means of the drive pulley ( 5 ), the transmission belt ( 6 ), the receptor pulley ( 7 ), the receptor pulley gear ( 8 ), the alternating shaft crown ( 10 ), the alternating shaft gear ( 18 ) and the drive gear ( 16 ), causes the turning of the moveable crown ( 12 ) and the fixed crown ( 13 ), with a slight difference of speeds due to the fact that the number of teeth differ by one unit. In this way, the moveable crown&#39;s circular cam ( 14 ) and the fixed crown&#39;s circular cam ( 15 ) change their relative position, causing an alternative movement of the moveable crown ( 12 ) between a fitted position with the pneumatic clutch receptor crown ( 20 ) and another disengaged parallel position. In any case, the pneumatic clutch output gear ( 28 ) does not move since the pneumatic clutch receptor crown ( 22 ) is separated from the pneumatic clutch drive gear ( 21 ) as it is submitted to an upwards stress caused by the action of the pneumatic clutch spring ( 27 ) on the pneumatic clutch output gear ( 28 ) itself. During this first phase the doll does not emit any sound while it walks, driven by the conventional walking mechanism ( 59 ) moved by a walking mechanism gear ( 9 ) connected to a receptor pulley ( 7 ). 
     The second operating phase takes place when water and air are supplied to the doll through the mouth ( 43 ) using a special flexible baby-bottle ( 61 ). This baby-bottle is designed to inject into the pneumatic accumulator ( 24 ) a minimum and absolutely controlled amount of water, which is achieved by installing on its base a non-return valve ( 62 ), consisting of two cylindrical bodies ( 63 ) ( 64 ) that define an interior cavity ( 65 ) in which an elastic disc ( 66 ) slides. This closes the valve when it rests on the origin assembly ( 63 ), while it lets water and air pass through when it rests on the destination assembly ( 64 ) since it does so on various projections that are inside it. Thus, the suction capacity of the baby-bottle ( 61 ) can be quite limited when its elastic walls are repeatedly pressed and released, which will assure that, after this operation, there will always be in the baby-bottle a very small amount of water. In this way the elastic bellows ( 51 ) expands when it fills with air, with a small amount of water remaining at the bottom of it and in the pneumatic tubes ( 44 ). 
     The system does not lose pressure due to the existence of a non-return valve ( 68 ) located on the pneumatic tube ( 44 ) near to the doll&#39;s mouth ( 43 ) and also because the outlet valve ( 45 ) remains closed. Consequently, the bellows cover rod ( 56 ) moves upwards making the sector ( 23 ) turn and it applies the pneumatic clutch receptor crown ( 22 ) against the pneumatic clutch drive gear ( 21 ), fitting both together. This allows the pneumatic clutch output gear ( 28 ) to turn when the moveable toothed crown ( 12 ) fits with the pneumatic clutch drive crown ( 20 ) in its alternating movement on the alternating shaft ( 11 ) itself transmitting a turning movement to the arm coupling ( 32 ), through the arm receptor crown ( 30 ), the arm shaft ( 31 ) and the friction washer ( 34 ), the turning of which will not stop until the coupling lever ( 38 ) hits against the butt end ( 39 ′) when the movement of the friction washer ( 34 ) will be produced and the arm spring ( 37 ) will have reached its maximum extended position. When the moveable crown ( 12 ) disengages from the pneumatic clutch drive crown ( 20 ) in the alternating movement of the former, the entire mechanical system from the latter up to the arm coupling ( 32 ) is freed, so the arm spring ( 37 ) will make the arm coupling ( 32 ) turn until it reaches its initial position. Consequently, the effect is that the doll repeatedly moves its hand to its crotch. Since in this position of the arm the arm clutch ( 29 ) is moving, the consumption of the electric motor ( 4 ) increases considerably, thus lowering the speed of the walking device ( 59 ) that can no longer make the doll walk, only transmitting an oscillating movement that simulates restlessness. During this second phase and while the doll moves its hand to its crotch, it emits a sound such as “mommy, pee . . . pee,” or something similar. 
     The third phase takes place when once the user has taken the doll&#39;s clothes off, lifts the elastic cylindrical body ( 50 ) from the position represented in FIG. 4, to the position represented in FIG. 5, making the outlet valve ( 45 ) go from a closed position to an opened one and the retained water in the interior of the pneumatic tubes ( 44 ) is expelled to the exterior with force under the action of the overpressure created in the elastic bellows ( 51 ) by the accumulator spring ( 52 ) simulating that the doll is urinating. It is of interest to point out that this third phase can be accomplished with the doll moving or static, whether the main switch ( 58 ) is kept connected or not. During this third phase, the doll emits the sound of passing water “drip . . . drip . . . drip.” 
     When the arm shaft ( 31 ) turns, a stub ( 70 ) eccentrically mounted on the arm coupling ( 32 ) also does so, transmitting a translation movement to an arm connecting rod ( 71 ) that articulates on it and that also ends eccentrically articulated on a prolongation ( 72 ) of the forearm ( 73 ) that can turn around an elbow pivot ( 74 ) on the arm ( 33 ). See FIG.  3 . 
     The walking mechanism ( 59 ) is already known from the application of the prior Utility Model U9002535 from the same applicant, so a very superficial description of its operation will be done. The walking mechanism gear ( 9 ) is connected to a primary crown ( 75 ), fitted into a secondary crown ( 75 ′), likewise connected to an eccentric ( 76 ) encased between the “U” branches of a flat plate ( 77 ), itself oscillating on a fixed shaft ( 78 ). The movement of the walking mechanism gear ( 9 ) is produced continuously, for which we will also continuously have an oscillating movement of the flat plate ( 77 ), that will be accomplished at two different speeds, depending on whether the arm clutch ( 29 ) is moving or not. This flat plate ( 77 ) has two side windows ( 79 ) designed to receive the radial prolongations ( 80 ) of each leg shafts ( 81 ) finishing in a ball joint ( 82 ) on which the legs ( 69 ) themselves are mounted. 
     With the objective to simplify, to the degree possible, the description of a preferred embodiment and maintain relatively controlled the number of references to the figures, only those elements have been described that are essential to characterize the invention, omitting the electrical schematic or the synchronizing between the electrical and pneumatic systems. Which will be performed preferably by means of magnets connected to the moving elements and fixed Reed relays, such as is usual and will be perfectly known, to any expert on the matter.
