Title: Form of articulated structures for dolls or puppet bodies

Description:
This application is a continuation of application Ser. No. 07/977,837 filed on Nov. 17, 1992, now abandoned. 
    
    
     BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention refers to improvements in the form of articulated structures for dolls or puppet bodies (henceforth, &#34;doll&#34;, which can also be the body of a puppet), which, in the function for which they are intended, contribute various advantages which furnish a notable advancement over presently employed articulated structures to the organization and construction of the articulated structures. 
     2. Description of Related Art 
     It is already known in the doll market that articulation means are incorporated which allow for the movement of the doll members in order to adopt various postures which add greater realism to the doll and which at the same time extend the realms of possible games to be played beyond those with nonarticulated structures. Without exception, in the present state of technology there have been no steps forward and the articulation means continue to suffer from the defect of their principal drawback which is their low resistance, due to which the very weight of the member or any slight pressure thereon is capable of altering the established position of the member. Thus the postures of the doll are not maintained in a fixed position for a long time, which would be an attractive feature in the toy. 
     SUMMARY OF THE INVENTION 
     By virtue of its experience in the manufacture of toys, and more particularly the manufacture of dolls in its broader sense, such as those which adopt human, animal or any other type of form, the company petitions that it has conceived improvements which can be applied to the articulated structure of dolls of the type described above, by virtue of which arbitrary and multiple positions and postures can be consigned to dolls, and can be held stable for an indefinite length of time, while not constituting any obstacle to the manipulation of the doll by the child who is voluntarily making new changes of position. 
     The improvements according to the present invention offer the advantages which have been described above, in addition to others which are to be easily deduced from the representational embodiment of an articulated structure incorporating said improvements for dolls, which are described in greater detail hereinafter to facilitate comprehension of the features described above and drawings are provided to show the various details and, accompanying the present account, taken solely as a nonlimiting example of the scope of the present invention, one practical embodiment of the object of the same is represented.

     FIGS. 12 and 13 show respectively a basic part provided to obtain the link connection and the link connection obtained from said part by careful injection of a new application of material, all with the objective of attaining improved sphericity. 
    
    
     DETAILED DESCRIPTION OF PREFERRED EMBODIMENT(S) 
     In the embodiment shown in the drawings, the articulated structure for dolls, furnished with the improvements of the invention and in accordance with one realization of the same, comprises a structure or skeleton-like framework constituted of the aforementioned structural elements, designated 1, 2 and 3, which correspond to the trunk, hips and neck or collar of a person; and members 4 and 5, and 6 and 7, making up the top and bottom extremities; and the link connections 8, which connect the aforementioned members with the principal elements 1, 2 and 3, and connect said principal elements among themselves. 
     Element 1 is constituted of a part manufactured of injected material which adopts a &#34;T&#34; configuration, shown in cross section in FIG. 3, shaped by ribs 11 which intersect orthogonally. The arms 1a of said part are essentially oblique, and the ends are finished by semispherical hollow forms, designated as 9, with recesses 10. 
     Element 2 is configured of a part comprising an obtuse angle of cross section identical to that of part 1, provided with semispheres 9 arranged in its ends and its apex. 
     Element 3, connected to element 1, is configured of a revolving cylindrical part, hollow and open at the top, with annular ribs 3a, and with a semisphere 9 at its bottom, with its opening to the exterior. 
     Member 4, forming both of the top extremities, presents a section 4--4, shown in FIG. 4, formed by ribs 12 which intersect orthogonally. Likewise, member 5, another component of said top extremities, presents a section 6--6, shown in FIG. 6, formed by intersecting ribs 13, one of them straight and the other in a double &#34;t&#34; shape, and shows a reduced cross section 5a, joining with an end 5b. 
     Member 4 presents semispheres 9 in its ends, with its opening at a 90 degree angle to the longitudinal axis of the member 4, while member 5 presents a semisphere of larger cross section at its end, with its opening aligned to a longitudinal axis of the member 4. 
     Member 5 presents a section 3--3, as shown in FIG. 3, and two semispherical ends of the same type as 9, with its opening arranged transverse and obliquely with respect to the longitudinal axis of said member. 
     Member 7 presents a section 6--6, as shown in FIG. 6, and a section 7--7, as shown in FIG. 7, formed by intersecting ribs 14 which join with an end 7a. 
     The link connections of the components described are configured by the parts 8 which comprise two spherical bodies 8a connected by a diametral appendix 8b. The surfaces of the spherical bodies can be smooth or else can include flat facets, curved concavely as in 8c, elongated fissures 8d, or some other type of protuberance or recess in order to offer frictional resistance with the inner surface of semispherical cavities 9, inside which they are to revolve, since this is the resistance which determines the fixation and immobility of the position adopted by the skeleton-like framework. The recesses 10 of these semispherical cavities coincide with the natural movement of the respective components, such as arms, legs, etc., in such a manner as to allow a greater inclination to swivel in this sense. 
     In some cases, a base part 15 is constructed beforehand to achieve improved sphericity in the link connections 8a, in the ends of which are constituted annular projections 15a. The material 16 is injected over said ends, and the material adopts a uniform spherical shape. 
     The structural components and members are joined with the link connections 8 during the actual manufacturing process, consisting of the injection of the material of the cited parts over the spheres 8a, in such a manner that they constitute an indivisible articulated whole. 
     The structural components and members, formed by longitudinal ribs which intersect orthogonally, present virtually circular cross sections, as can be appreciated in FIGS. 3 to 7.
