     BACKGROUND OF THE INVENTION  
       [0002]     Field of the Invention  
         [0003]     The invention relates to a toy figure, in particular, a functional doll, including a central torso with a body shell that encloses a cavity in the interior of the torso, and a plurality of extremities that are disposed on the torso, such as a head, arms and legs, at least the arms and legs being formed from flexurally elastic material. A functional device for ensuring one or more functions typical of a functional doll is integrated in the toy figure, the functional alignment including a central functional section that is accommodated in the torso of the toy figure and at least one peripheral functional section that is disposed in an associated extremity.  
         [0004]     Toy figures, in particular, so-called functional dolls, in which a series of predetermined functions integrated in the toy figure increase the play value have been available for some time now. For example, dolls that laugh, cry, wet themselves, swallow, and excrete soft food or can make certain sounds are known. It is often the case that these toy figures require batteries. A durable toy figure that is particularly unsusceptible to malfunctioning can be achieved if these functions are triggered mechanically, pneumatically, and/or hydraulically rather than electrically.  
       SUMMARY OF THE INVENTION  
       [0005]     It is accordingly an object of the invention to provide a toy figure, in particular, a functional doll, that overcomes the hereinafore-mentioned disadvantages of the heretofore-known devices of this general type and that further increases the extent of a play value of the toy.  
         [0006]     With the foregoing and other objects in view, there is provided, in accordance with the invention, a toy figure, including a central torso having a body shell enclosing a cavity in an interior of the torso, a plurality of extremities disposed on the torso, the extremities including at least one of a head, arms, and legs, at least the arms and the legs being formed from a flexurally elastic material, an integrated functional device having a central functional section disposed in the torso and at least one peripheral functional section disposed in an associated one of the extremities, joint connections rotatably mounting at least one of the arms, the legs, and the head on the torso, at least one of the joint connections having seals fluid-tightly sealing the torso and the at least one of the arms, the legs, and the head, a transfer device guided through at least one of the fluid-tight joint connections, and the at least one peripheral functional section being in at least one of mechanical, pneumatic, and hydraulic operative connection with the central functional section through an associated one of the fluid-tight joint connections.  
         [0007]     It is a basic idea of the present invention for such a toy figure equipped with joints and functions to be configured as a doll for playing with in the bath. The provision of suitable sealing measures in the region of the joint connections gives the toy figure a fluid-tight construction. Transfer measures, at the same time, are guided through the fluid-tight joint connection such that at least one peripheral functional section is in mechanical and/or pneumatic and/or hydraulic operative connection with the central functional section through the associated fluid-tight joint connection. The sealing measures in the region of the joint connections prevent water from passing into the hollow torso or the hollow extremities, in particular, the head, the arms, or legs.  
         [0008]     It has been found that the conventional toy figures with generic integrated functional devices have the disadvantage that, on account of the joint connections, they were not sufficiently fluid-tight to be brought into contact with water. For the users, predominantly children from three to ten years of age, the play value of a toy figure, in particular, a functional doll, can be significantly increased by it also being possible for this figure or doll to be introduced into a basic of water, in particular, into a bathtub, or even held under running water.  
         [0009]     With the conventional functional dolls, in such a case, water penetrates through the joint connections. As a result, the functional device may be damaged, but, at the very least, water remains in the toy figure, which is extremely undesirable for hygiene-related reasons.  
         [0010]     In accordance with another feature of the invention, at least two peripheral functional sections are provided in two different extremities that are each in operative connection with the central functional section. Such a peripheral function may be formed, for example, by a compressible chamber that is formed in the arm and the compression of which causes a certain function, in particular, the flow of tears, to be triggered by the functional device. The second peripheral functional section may be configured, for example, as a pressure slide within a flexurally elastic leg, to actuate a valve in the central functional section.  
         [0011]     In accordance with a further feature of the invention, for the peripheral functional section to be connected to the central functional section in each case through the fluid-tight joint connections, mechanical and/or hydraulic and/or pneumatic transfer measures that may include, for example, one or more hoses or lines or an actuating slide are provided in the region of these fluid-tight joint connections.  
         [0012]     In accordance with an added feature of the invention, first joint elements are provided on the torso and can be brought into engagement with second, respectively correspondingly configured joint elements on the extremities, at least one of the first joint elements including a respective recess that is provided on the torso and into which the second joint elements can be latched. These first joint elements are, preferably, integrally formed on the torso so that this constitutes a favorable solution as far as the production costs are concerned. Furthermore, this solution, in the case of a functional doll, allows realistic modeling of human behavior—as far as the pivoting movement and the pivoting plane of the joint are concerned—to be achieved in a comparatively favorable manner.  
         [0013]     In accordance with an additional feature of the invention, the fluid-tight sealing may be effected by forming the first joint elements provided on the torso in each case in a joint cage belonging to the torso and partitioning them off in a fluid-tight manner in the direction of the cavity of the torso in each case by a sealing wall of the associated joint cage. The mechanical and/or pneumatic and/or hydraulic transfer measures are guided through the sealing walls in a fluid-tight mount or fluid-tight sealing being effective between the sealing walls and the second joint elements.  
         [0014]     The first joint elements, which are, preferably, likewise integrally formed on the torso, are partitioned off in a cage-like manner from the cavity by the sealing walls. It is also the case in this configuration that the body shell is, preferably, welded together from two parts, with the result that a sufficiently high rear-engagement measures can be formed in the region between the sealing walls and the first joint elements so that the second joint elements can be latched in permanently on the torso. In a specific configuration, it is also possible for the fluid-tight mount mentioned to fix an associated transfer measures, for example, a hose, in a fully fluid-tight manner, in particular, by adhesive bonding or welding. Any rotary movements can, then, be absorbed by twisting of the hose or by a separate rotary bearing.  
         [0015]     In accordance with yet another feature of the invention, the fluid-tight mount, itself, is configured as a rotary bearing for ensuring a fluid-tight rotary movement between the sealing wall and the transfer measures. For example, an actuating slide can be mounted in a fluid-tight manner within the sealing wall along the axis of rotation of the joint movement.  
         [0016]     In accordance with yet a further feature of the invention, the joint cages that are, preferably, provided act as stiffening measures to effect a sealing fit that is reliable even under stressing. The fluid-tight mounting has to be ensured even when, within the context of customary handling of the toy figure, the extremities are also subjected to transverse forces. In a configuration that is further regarded as advantageous, the sealing walls are, thus, more torsionally rigid than the body shell of the toy figure.  
         [0017]     In accordance with yet an added feature of the invention, the joint cages can be inserted as separate components into the torso. As an alternative, the joint cages or two half-shells that form a joint cage can be integrally formed on the torso or on the half-bodies thereof.  
         [0018]     If the joint cages are configured as separate components, it is also possible to use, for such a purpose, a material that differs from, in particular, is harder than, the material of the body shell. In the case of the joint cages being integrally formed on the half-bodies of the torso, it is recommended for the joint cages also to be integrally formed as half-shells in each case.  
         [0019]     In accordance with yet an additional feature of the invention, at least one peripheral functional section is configured as an actuating device for triggering a certain function of the functional device, in particular—as has already been mentioned—as a compressible chamber, as an eccentric or as a pressure slide.  
         [0020]     It is also possible, in accordance with again another feature of the invention, for at least one peripheral functional section to be configured as an effect-producing device, in particular, as a tear outlet and/or as food-/drink-receiver, for ensuring a predetermined play effect. Here too, it is important to have reliable transfer measures, between the central functional section and the peripheral functional section, which are guided through the fluid-tight joint connections and which are configured for the respectively envisaged rotary movements between the torso and extremity. In accordance with again a further feature of the invention, at least one peripheral functional section is three peripheral functional sections disposed in three different ones of the extremities, each of the three peripheral functional sections being in operative connection with the central functional section, and the three different ones of the extremities include the head, one of the arms, and one of the legs  
         [0021]     In accordance with again an added feature of the invention, for sealing the joint connections, first joint elements are provided on the torso and can be brought into engagement with second, respectively correspondingly configured joint elements on the extremities, annular sealing measures being disposed between at least one first joint element and the associated second joint element and effecting fluid-tight sealing of the respective joint connection even in the case of rotary movement between the first and second joint elements.  
         [0022]     This possible sealing method may be provided as an alternative, or in addition, to the already mentioned sealing by the sealing walls in the region of the first joint elements within the torso. A preferred configuration is one that does not have these separately provided sealing walls because there is, then, no need to produce the latter and it is also the case that the transfer measures need not be guided through the sealing walls. The annular sealing measures may be configured here such that it is effective in the region of the bearing surfaces between the first and second joint elements and effects reliable sealing in any envisaged rotary position. To reduce frictional forces and wear and to increase the sealing action, a sealing lubricant, for example, silicone lubrication, may be provided in addition.  
         [0023]     In accordance with again an additional feature of the invention, of the first (torso-side) joint elements, the latter include a disk-like base plate that is, preferably, integrally formed with the body shell and has an outer and an inner abutment surface, the base plate containing a recess that is provided for the insertion of the associated second joint element and has a circular inner surface. Accommodating devices for fastening the annular sealing measures are provided on this circular inner surface. This disk-like base plate, in particular, the circular inner surface thereof, defines a stable bearing surface on which the annular sealing measures can be provided at the same time. In a specific configuration, the accommodating devices for the annular sealing measures may include an encircling groove such that the annular sealing measures are retained in position by the encircling groove.  
         [0024]     In accordance with still another feature of the invention, the second joint elements are configured to correspond to the first joint elements and may include two mating plates that are spaced apart from one another at a predetermined distance by an encircling joint groove, at least certain portions of the resulting joint groove defining sliding surfaces for the joint connection, and these and/or other portions forming a bearing surface for the annular sealing measures within the joint groove.  
         [0025]     In accordance with still a further feature of the invention, the annular sealing measures may be configured as an O-ring. This configuration results in durable and reliable sealing between the first and second joint elements, the elasticity of the O-ring being capable of compensating for production tolerances, deformation and wear.  
         [0026]     In accordance with still an added feature of the invention, that is particularly favorable in production terms, the annular sealing measures are configured as an encircling sealing lip that is formed, on the torso side, on the first joint element or the second joint element, which is associated with an extremity, preferably, connected integrally to the first joint element or to the second joint element. Production and installation costs are favorable precisely in the case of integrally forming this sealing lip.  
         [0027]     In accordance with still an additional feature of the invention, the annular sealing element may be configured as a cross-sectionally U-shaped double ring or grooved ring with an outer and an inner sealing lip. On account of its elasticity already being provided by the shape, such a sealing element is particularly well suited for compensating for any production tolerances, deformation, or signs of wear.  
         [0028]     In accordance with another feature of the invention, the body shell of the torso of the toy figure is formed from two half-bodies that are welded to one another at the manufacturer. This gives the manufacturer more freedom in constructing the body shell. Even undercut regions, in particular, for forming the first joint elements, can, thus, be realized with justifiable production outlay.  
         [0029]     In accordance with a further feature of the invention, production of the toy figure by welding two half-bodies is carried out even in the case of the torso having a length of over 150 mm, preferably, of over 160 mm, in particular, of over 170 mm.  
         [0030]     In accordance with an added feature of the invention, the reinforcing inserts have an outwardly oriented planar front surface.  
         [0031]     In accordance with an additional feature of the invention, the arms and/or legs are stiffened in the region of the joint connections by reinforcing inserts. It is precisely in the case of the flexurally elastic arms and/or legs, which are usually configured as hollow bodies, that there is the problem of these possibly being deformed, under unfavorable loading, such that, without reinforcing inserts, a fluid-tight joint connection possibly cannot be ensured with a sufficient degree of reliability. It is, thus, a particular discovery that the reliability of the fluid-tight joint connection according to the invention, through which transfer measures of a functional unit are guided, can still be increased to a significant extent by reinforcing inserts.  
         [0032]     In accordance with yet another feature of the invention, the reinforcing inserts have a cylindrical basic body with a termination plate that is joined thereto and is of slightly larger dimensions in the radial direction. The reinforcing inserts are inserted into a correspondingly configured recess of the associated joint element, this recess being configured as a cylindrical opening that is bounded at the top by an encircling groove. The termination plate reinforces the joint element as far as its distal periphery. Deformation of the flexurally elastic arms and/or legs, then, cannot give rise to any deformation in the region of the joint connections that is critical for the functioning of the fluid sealing.  
         [0033]     Although basically not necessarily integral positioning of the first joint element in relation to the torso (and, likewise, not necessarily integral positioning of the second joint element in relation to the extremities) is preferred, it is also possible, in accordance with a concomitant feature of the invention, as an alternative, for the fluid-tight joint connections to be configured as separate components that are, then, fastened in a fluid-tight manner. In particular, they are attached by welding and/or adhesive bonding between the torso and associated extremity. In these alternatives, it would be possible for the fluid-tight joint connections to be optimized in terms of their fluid-sealing function and of the lead-through of the transfer measures, without account being taken of the production process of the body shell or of the extremities. Connection of the transfer measures and fastening of the joint connections to the torso and the extremities, however, would, then, give rise to additional outlay during assembly of the toy figure.  
         [0034]     Other features that are considered as characteristic for the invention are set forth in the appended claims.  
         [0035]     Although the invention is illustrated and described herein as embodied in a toy figure, in particular, functional doll, it is, nevertheless, not intended to be limited to the details shown because various modifications and structural changes may be made therein without departing from the spirit of the invention and within the scope and range of equivalents of the claims.  
         [0036]     The construction and method of operation of the invention, however, together with additional objects and advantages thereof, will be best understood from the following description of specific embodiments when read in connection with the accompanying drawings.

     DESCRIPTION OF THE PREFERRED EMBODIMENTS  
       [0053]     Referring now to the figures of the drawings in detail and first, particularly to  FIG. 1  thereof, there is shown a partly sectional view of one embodiment of a functional doll. The functional doll includes a torso  11  that is made up of two half-bodies  52 ,  53 , forms a body shell  35  and has extremities disposed on it, namely, a head  12 , arms  13 ,  14  and legs  15 ,  16 . A cavity  34  is formed within the torso  11 .  
         [0054]     The arms  13 ,  14  are connected to the torso  11  through fluid-tight joint connections  18 ,  19  configured as arm joints and the legs  15 ,  16  are connected through fluid-tight joint connections  20 ,  21  configured as leg joints. Finally, the head is connected to the torso  11  through a likewise fluid-tight joint connection  22  configured as a neck joint.  
         [0055]     Accommodated within the functional doll is a functional device  17  that has a central functional section  62  provided in the torso  11  and one or more peripheral functional sections provided in the extremities  12  to  16 . The peripheral functional sections, here, specifically include a compressible chamber  26 , an eccentric  27 , a pressure slide  28 , a tearing outlet  29  (see  FIG. 2B ), and a food-/drink-receiver  30  (see  FIG. 2B ).  
         [0056]     The central functional section  62  and the peripheral functional sections  26  to  30  are connected to one another through hydraulic and/or pneumatic and/or mechanical transfer measures that are to be explained in more detail below.  
         [0057]     Provided between the head  12  and torso  11  are lines  31 ,  32  that connect the food-/drink-receiver  30  to a drink tank  65  and a storage tube  66 , which serves as a food tank. The storage tube  66  serving as a food tank is oriented to run in a rectilinear manner parallel to the axis of the body of the functional doll, and is connected to a first evacuation opening  68  through a valve device  10 . It, preferably, is of a material that can be twisted over a certain angle range to follow pivoting movements of the head. The drink tank  65 , for its part, is connected to a second evacuation opening  70  through an outflow line  69 .  
         [0058]     The already mentioned compressible chamber  26  is formed on or in the arm  13  of the functional doll. The compressible chamber  26  is in pneumatic operative connection with the cavity  34  formed in the torso  11 , such that, when the arm  13  formed from flexurally elastic material is compressed, air is forced through the joint connection  18 , through a first valve connector  72  and through a hose  71 , into a tears tank  74  filled with liquid. A predetermined quantity of liquid is, thus, fed out of the tears tank  74  through a line  85 , into the region of the eye sockets  86  of the functional doll and flows out of one or both eyes  75 . The tears tank  74  may have a refilling device that is coupled to the food-/drink-receiver  30 . For the arm  13  to be allowed to relax into its starting position and, at the same time, for the volume, which increases again in the process, not to be filled with liquid from the tears tank  74 , a second valve connector  73  is provided within the joint connection  18 . Connected to the second valve connector  73  is an air-admission line  87  through which air can be taken in for the purpose of filling the cavity  34 . First and second valve connectors  72 ,  73  each have non-illustrated non-return valves so that, through the first valve connector  72 , air is always ejected out of the arm  13  in the direction of the tears tank  74  and, through the second valve connector  73 , renewed filling of the arm  13  with air is ensured.  
         [0059]     Finally, the cavity  34  of the torso also contains a mechanical voice  76 , which is known per se in the case of toy figures. The mechanical voice  76  produces a pre-selected sound when the functional doll changes position.  
         [0060]     The already mentioned valve device  10  can be actuated through the fluid-tight joint connection  20 . The valve device  10  includes, in the first instance, a valve chamber  77  with a valve piston  78  that is mounted in a displaceable manner therein and has a through-passage opening  79  provided for the through-passage of fluid in the open position of the valve device  10 . The valve piston  78  is retained in the closed position by the action of a spring  80 . The valve piston  78  is sealed in a fluid-tight manner in relation to the cylindrical valve chambers  77  through two sealing disks or O-rings  81 ,  82 .  
         [0061]     By an actuating slide  33 , which projects into the joint connection  20 , and of the pressure slide  28 , which is disposed in a rotationally fixed manner on this actuation slide  33 , it is possible to actuate the valve piston  78 , in the case of the pressure slide  28  being subjected to pressure, in a certain angular position or in a certain angle range of the leg  15  in relation to the torso  11 . Outside such an angular position or the angle range, a translatory displacement of the valve piston  78  does not result in an open position of the valve device  10 , which is explained in more detail in the applicant&#39;s parallel application of the same date.  
         [0062]      FIG. 2A  illustrates an alternative embodiment of a functional doll as seen schematically partly in cross-section. The embodiment illustrated here differs from the embodiment explained with reference to  FIG. 1  substantially by modification of the fluid-tight joint connections  18  to  22 . The joint connections of the embodiment illustrated in  FIG. 1  will be explained in more detail at a later stage in the text with reference to FIGS.  7  to  9 . The joint connections used in the embodiment according to  FIG. 2A a are, likewise, illustrated in more detail with reference to  FIG. 10A . The significant difference is that the joint connections are partitioned off in relation to the cavity  34  of the torso  11  by joint cages  42  that have corresponding sealing walls  24 . In such a case, the transfer measures, in particular, an air channel  88 , and the actuation slide  33  are guided in a fluid-tight manner through the sealing wall  24  of the joint cages  42 , which will be described in more detail with reference to  FIG. 10A .  
         [0063]      FIG. 2B  illustrates a schematic diagram, in a lateral sectional view, of a functional doll corresponding to the embodiment shown in  FIG. 1  or  2 A. It can be seen here that the already mentioned lines  31 ,  32  and the storage tube  66  are guided through the joint connection  22  that forms the neck of the doll.  
         [0064]      FIG. 2C  illustrates, in simplified form, a basic sectional view through a functional doll according to the embodiment shown in  FIG. 2A . It is possible to see the joint connections  18 ,  19  of the arms  13 ,  14 , these joint connections  18 ,  19  being retained in joint cages  42 , respectively. Integrally formed on the joint connection  18  is an air-admission and air-extraction connection  89 , which is connected to an air channel  88  through the joint connection  19 . Located on the air-admission and air-extraction connection  89 , in turn, are the first valve connector  72  and the second valve connector  73  (concealed in  FIG. 2C ) for the connection of a hose  71  and of the air-admission line  87 , respectively. See  FIG. 1 .  
         [0065]     Various preferred configurations of the fluid-tight joint connection  18  to  22  are explained in more detail hereinbelow.  
         [0066]      FIGS. 3A, 3B , and  4  illustrate a first alternative configuration for a fluid-tight joint connection. The already mentioned torso  11  contains a plurality of base plates  43 , in which first joint elements  36 ,  37 ,  63  (see also  FIGS. 1 and 9 ) are provided and into which correspondingly configured second joint elements  38 ,  39 ,  64  can be inserted. Whereas, in the case of the embodiments illustrated here, the second joint elements  38 ,  39  of the arms  13 ,  14  and legs  15 ,  16  are integrally formed with the associated arms  13 ,  14  and legs  15 ,  16 , the second joint element  64  of the head  12  is configured as a separate component, which is, then, adhesively bonded or welded to the head.  
         [0067]     The first joint elements  36 ,  37 ,  63  include recesses  40 ,  41 ,  83  that are each provided in the base plates  43  and into which the second joint elements  38 ,  39 ,  64  can be inserted. The recesses each include an inner surface  46  that bounds the recesses along the circumference and on which an accommodating device, in particular, a tapering groove  47 , is provided. In the case of the embodiment that is illustrated with reference to  FIGS. 3A, 3B  and  4 , the groove  47  is defined by a notch with two surfaces running toward one another, a correspondingly configured sealing lip  54  of the second joint elements  38 ,  39  engaging in this notch. The second joint elements  38 ,  39  include mating plates  49 ,  50  that are spaced apart from one another by an encircling joint groove  48 . The spacing between the joint plates  49 ,  50  corresponds approximately to the thickness of the base plate  43  formed on the first joint elements  36 ,  37 ,  63 . The mating plates  49 ,  50 —as can be seen from  FIG. 4 —engage around the base plate  43  such that the joint connections  18  to  22  is stabilized by the abutment of the mating plates  49 ,  50  in each case against an inner abutment surface  45  and an outer abutment surface  44  of the base plate  43 . The mating plate  49  here forms the joint-side termination of an extremity  12  to  16 , whereas the mating plate  50  can merge, at the periphery, into the contour of the associated extremity.  
         [0068]     The sealing lip  54  provided in the encircling joint groove  48  is configured to correspond to the shaping of the groove  47  provided in the first joint element  36 ,  37 ,  63 . The sealing lip  54 , at the same time, forms a bearing surface  51  for the joint connection  18  to  22 .  
         [0069]     In the configuration that is specifically proposed here, the sealing lip  54  is formed integrally with the associated extremity  12  to  16 , which reduces the production costs. To ensure the desired fluid sealing with a sufficient level of reliability, however, it is very important for the sealing lip  54  and groove  47  to be coordinated precisely with one another. It goes without saying that, in respect of a kinematic reversal, it is also possible for the groove  47  to be formed on the second joint elements  38 ,  39 ,  64  of the extremities  12  to  16  and for a correspondingly configured sealing lip  54  to be provided within the first joint elements  36 ,  37 ,  63 .  
         [0070]      FIGS. 5A, 5B , and  6  illustrate an alternative embodiment for fluid-tight sealing of the joint connections  18  to  22 . The sealing here, rather than being achieved by a sealing lip  54  which corresponds with an appropriate groove  47 , is achieved by an O-ring  23  that is effective between the first joint element  36 ,  37 ,  63  and the second joint element  38 ,  39 ,  64 . The groove  47  on the inner surface  46  of the recess  40 ,  41 ,  83  of the torso  11  is shaped appropriately to stabilize the O-ring  23 . Correspondingly, the encircling joint groove  48  of the second joint element  38 ,  39 ,  64  is provided with a cross-sectional shape that stabilizes the O-ring  23 . At the same time, however, a bearing surface  51  possibly including a plurality of portions is defined within the encircling joint groove  48 , this bearing surface sliding on the base plate  43  of the first joint elements  36 ,  37 ,  63 .  
         [0071]     The sealing by an O-ring  23  is extremely reliable and durable and also compensates for slight production tolerances that are present in certain circumstances.  
         [0072]     Finally,  FIGS. 7, 8  and  9  illustrate a third alternative embodiment for fluid-tight sealing of the joint connections  18  to  22  that corresponds to the sealing illustrated in  FIG. 1 . In this case, instead of an O-ring  23 , a double ring  25 , which may also be referred to as a grooved ring, is inserted, for sealing purposes, between the inner surface  46  of the recesses  40 ,  41 ,  83 , that are provided within the base plate  43 , and the encircling joint groove  48  of the second joint element  38 ,  39 ,  64 . A correspondingly configured groove  47  on the inner surface  46  of the base plate  43  may be dispensed with, as is illustrated with reference to  FIGS. 7, 8  and  9 . The double ring  25  includes an outer sealing lip  55  and an inner sealing lip  56 , which are connected to one another at a common base  84  and can be deflected elastically in relation to one another at their distal ends.  
         [0073]     As is shown with reference to  FIG. 8 , the double ring  25 , for installation purposes, may be drawn onto the second joint elements  38 ,  39 ,  64  and is retained there in the encircling joint groove  48 .  
         [0074]     To limit the deformation of the second joint elements  38 ,  39 ,  64  such that, in the case of normal usage, fluid-tight sealing of the functional doll remains ensured even if the extremities  12  to  16  are deformed, reinforcing inserts  57  (see  FIGS. 1, 2A ,  4 ,  6 ,  10 A) are inserted in the second joint elements  38 ,  39 ,  64  in each case. These reinforcing inserts  57  include a cylindrical basic body  59  with a termination plate  60  disposed at the end thereof. The termination plate  60  has a planar front surface  58 . The reinforcing inserts  57  can be inserted in each case into a correspondingly shaped recess within the second joint elements  38 ,  39 ,  64 , a groove  61  being integrally formed on the periphery of the second joint elements for the purpose of accommodating the termination plate  60  in a flush manner. See,  FIG. 8 . The second joint elements  38 ,  39 ,  64  are, thus, stiffened precisely in their distal region, namely at the outer mating plate  49 , by the termination plate  60  of the respective reinforcing insert  57 .  
         [0075]      FIG. 10A  illustrates a fluid-tight joint connection  20  that is partitioned off from the cavity  34  of the torso  11  by a joint cage  42 . In the embodiment of  FIG. 10A , the joint cage  42  is formed by a sealing wall  24  that has a substantially cup-like basic shape and directly adjoins the body shell  35  in the inward direction such that the recess  41 , which is provided in the outward direction for the insertion of the second joint element  39 , has a smaller diameter than the joint cage  42  formed by the, in this case, substantially cup-like sealing wall  24 . The second joint element  39  is retained in these undercuts formed in this way, in which case, the first joint element  37  here need not just include the recess formed in the body shell  35 ; rather, the joint cage, which as far as possible has a corresponding configuration, can also perform a guidance function for guiding the second joint element  39 , as is also illustrated with the present embodiment. However, it is not in any way imperative for the joint cage  42  to perform such a joint or guidance function. Rather, it may be sufficient for the first joint element to be formed in a base plate  43  in the body shell  35  that is provided with a recess  41  and outer abutment surface  44  and inner abutment surface  45 .  
         [0076]     The sealing walls  24  of the joint cages  42  predominantly have a sealing function. For such a purpose, they have a central opening  90  through which the transfer devices are, in this case, specifically the actuating slide  33 , is, guided. An O-ring  91  is retained in the central opening  90  to seal the actuating slide  33  in a fluid-tight manner in relation to the cavity  34  of the torso  11  during a rotary or translatory movement of the actuating slide. Correspondingly—as can be seen from  FIG. 2A —the air channel  88  is guided through the central opening  90  of the sealing wall  24 , here, too, an O-ring  91  being provided for fluid-tight sealing between the air channel  88  and sealing wall  24 .  
         [0077]     In the case of the embodiment illustrated here, the O-ring  91 , rather than butting directly against the actuating slide  33 , effects sealing between the termination plate  60  of the second joint element and the sealing wall  24 . As an alternative, however, it is also conceivable for the sealing to take place directly between the sealing wall  24  and the actuating slide  33 .  
         [0078]      FIG. 10B  illustrates a half-body for a torso of a functional doll in which half-shells of joint cages  42  can be inserted at the leg joints  20 ,  21 . A half-shell  92  is provided with an outer groove  93 , which can be latched onto a protrusion  94  formed on the half-body  52  of the body shell  35 .  
         [0079]      FIG. 10C  illustrates an alternative embodiment, in which the half-shells  92  for the leg joints  20 ,  21  are formed integrally with the half-body  52  of the body shell  35 . In both embodiments illustrated, the joint cages  42  for the arm joints  18 ,  19  are integrally formed on the body shell  35 .
