TECHNICAL FIELD 
     The present invention relates to the field of recreational and furnishing equipments in structures such as nurseries, day cares and games rooms in pediatric hospitals. In particular, the present invention relates to a recreational structure comprising wheels suitable to entertain and transport children up to 36 months, in a complete safe manner. 
     STATE OF THE ART 
     The need of having the following devices, inside structures that host children in the age range from 3 to 36 months, is known from the prior art:
         1. small trucks for the transportation of children;   2. mattresses and containing toys, for example tubs;   3. containers to store toys, for example boxes.       

     No structures are known, that give the possibility to satisfy all these needs at the same time. 
     Tracks for the transportation of a children are known from the state of the art, but these do not have the security features needed in case of fire or earthquakes, because they are not provided with a covering structure. 
     Toys that can contain children (coaches, pillows, pools with little balls and others) are known as well, but they do not have wheels. 
     The proposed solution according to the present invention solves all these needs offering, by the use of a single object:
         1. the possibility to transport and secure the children protecting them from falling objects and at the same time from fire and flames;   2. the possibility to contain and entertain them like in a playpen, ensuring that they cannot exit;   3. the possibility to contain and transport toys.       

     These aims are ensured using a mobile recreational structure in which children can play and can be transported and secured, and which also can contain and transport toys, having the features described, shown and claimed in the following. 
     SUMMARY OF THE INVENTION

     DETAILED DESCRIPTION OF THE INVENTION 
     First of all it is necessary to think about the undeniable fact that a group of children up to 36 months is not able to save itself, for example, in case of fire or earthquake. Accordingly, an adult who has to deal with the emergency of escaping from fire or trying finding a safe place during an earthquake and has to take care of more than two small children, for example, up to 36 months, does not have the possibility to save all of them and to save himself. 
     According to the state of the art, there is no “wagon” able to transport children quickly to a safe place in order to escape from a fire nor is there a structure under which the adult and the children can protect themselves from falling objects. 
     Therefore, the extraordinary and exceptional use of this mobile recreational structure is that of being used as a transportation mean for children in case of fire and that of being used as a shelter for the children and the adult in case of an earthquake. 
     In case of fire, the adult quickly introduces all the children belonging to the group inside the mobile recreational structure, then he lifts up from the ground the rear door, which has been previously used as a ramp and he puts it into place using magnets. At this point, with the mobile recreational structure closed, he unlocks the wheels with his foot and quickly walks through the exit pushing from behind the mobile recreational structure and looking, at the same time, at the children inside it, eased along the way by the curved front part of the mobile recreational structure. 
     In case of an earthquake, the adult introduces the children into the mobile recreational structure pushing them toward the front part, then he himself enters into the structure, closes the rear door and remains inside with the children until the end of the earthquake. Afterwards the adult exits and brings the children safely outside the building carrying them inside the mobile recreational structure. 
     It has to be hoped that the use in case of earthquake or fire is extraordinary, but it must not been underestimated that this use could be the only possibility of salvation for the children and the adult in case of tragic events. 
     There is, in any case, the possibility of using the mobile recreational structure daily, by using its containing and transporting functions. 
     The structure can be used to secure some children, while the adult pays attention to only a child or during cleaning activities; it can also be used as a special bed for a child that needs to be taken under particular control; it can become a cozy place for reading tales to the smallest children; it can be used to temporary store the objects that the children must not see or reach; it can be used as a transportation means for children outside buildings and also, for the smallest, for moving them inside buildings; it can be the first location game for the children that are already walking and can go inside and outside in an independent way and can play inside it. 
     The invention is now described in a detailed manner with reference to the Figures of the attached drawings, which represent a non-limiting example. 
       FIG. 1  shows a cross-section of the recreational structure. 
     The structural part is made up by a rigid base  1  made of wood or another appropriate material, supported by four or more wheels  5 . 
     The perimeter is closed by a rigid structure  2  that can be a woven metallic net  2 . 1  and can be covered from the outside with a waterproof cloth  2 . 2 . 
     Inside it is protected by an easily washable padding made of a non-toxic material since it is the most exposed to the contact with the children. The padding is both on the side walls  3 . 1  and on the bottom  3 . 2 . 
     The supporting structure of the barrel vault covering  4  is made of bars made of steel or another compression resistant material which hold a reinforced cloth  4 . 2  made of carbon fibers or another suitable material. 
     It is equipped with four or more wheels, two in front and two nearby behind, made of polyurethane with a nuclei made of aluminum or another suitable material. The rear right wheel is provided with a breaking security system. 
     A music box, easily activated by the children using a rope, can be placed inside and the side walls  6  can be equipped with pockets to store small recreational objects. 
     All the materials used to produce the structure are, of course, made of fire resistant material, suitable to be used inside a school or a hospital, moreover the structure has to be free of small objects or blunt objects so that it can be freely used also by children under 36 months of age. 
       FIGS. 2, 3, 4 and 5  show different views of the structure respectively, from the front, from behind, laterally and from above. 
     In the above-cited Figures, it can be noted that the mobile structure is closed on the sides and on the front in a round shape. 
     In  FIG. 5 , it can be noted that the structure can be opened from the rear side using a door which, being hinged on the bottom, can be opened in a complete way, transforming itself into a sliding ramp  7 . 
     The front part has a round shape so as to make the passage through small paths, such as doors or corridors, easier. 
     Every single detail of the attached Figures is indicated with the following numbers.
       1 . rigid base     2 . side closing     2 . 1 . metallic net     2 . 2 . waterproof cloth     3 . 1 . side padding     3 . 2 . bottom padding     4 . barrel vault covering     4 . 1 . metallic bars     4 . 2 . protective cloth     5 . wheels     6 . equipped soft walls     7 . opening and sliding door   

     It is specified that the suggested dimensions are of about 150 cm in length×80 cm in width×140 cm in height but this can be varied according to the needs of the market. The proportions and the dimension of the structures of the various technical components can be varied and also the materials can be varied according to different technological needs. 
     It should be noted, in any case, that the present invention is not limited to the embodiments previously described and shown in the drawings. On the contrary, all the variations and modifications of the present embodiments that are clear to the person skilled in the art, are to be considered protected by the present invention.
