Description:
OBJECT OF THE INVENTION 
       [0001]    As stated in the title of this descriptive specification, the following invention relates to a toy comprising an improved three-dimensional puzzle, these improvements being incorporated into the object claimed in Patent WO 2004/030776, the toy essentially comprising a base body and a plurality of three different types of elements which are mounted to the base body, whereby groups of elements can be rotated in order to form the desired toy. In this way, the elements of the toy can be controlled simply and conveniently, while optimum stability and strength are obtained. 
         [0002]    To achieve this, the base body is defined by two concentric spheres between which are arranged some channell-shapped recesses for the mounting of some first elements among the set of elements, and with respect to which first elements some second elements are mounted, in order to complete the assembly with the insertion of a third type of unit element. 
       FIELD OF APPLICATION 
       [0003]    The present specification describes certain improvements of application in a three-dimension puzzle consisting of a base body and a set of elements according to three different types, being of special application for its incorporation into the object of patent WO 2004/030776. 
       PRIOR ART OF THE INVENTION 
       [0004]    Among the existing prior art we can cite the actual documents located in the search report for patent WO 2004/030776, which make reference to documents RU 2064315, SU 1136820, U.S. Pat. No. 5,452,895 and SU 1618432, all of them being regarded as belonging to the prior art. 
         [0005]    We can likewise consider document RU 1452535 already cited in patent WO 2004/030776. 
         [0006]    Moreover, patent WO 2004/030776 describes a puzzle, of general hollow spherical shape, based on certain elements according to two types, said elements being formed when the sphere is dissected by means of three planes perpendicular to its vertical axis and, moreover, dissecting the sphere by three planes perpendicular to a first horizontal axis and by another three planes perpendicular to a second horizontal axis perpendicular to the first. 
         [0007]    In this way, the elements obtained in a first and second type are joined together by means of a third element of attachment. 
       DESCRIPTION OF THE INVENTION 
       [0008]    The present specification describes a toy comprising an improved three-dimensional puzzle, these improvements being incorporated into the object claimed in Patent WO 2004/030776, the toy comprising a base body and a set of elements that can be mounted to the base body, the set of elements being mounted with the possibility of displacement according to groups of elements in order to create the desired toy, in such a way that the three-dimensional puzzle comprises:
       a base body defined by two concentric spheres sectioned by three pairs of planes in the separation zone between them, the planes of each pair being parallel and the three pairs of planes being orthogonal to each other and decentred, creating certain openings that are prolonged internally in some recesses perimetric to those openings, which define some channell-shapped recesses between both spheres, the imaginary outer sphere being constituted by four surfaces, three of them being equal and the fourth surface, different and of larger size, has a hole in its central position that passes through with respect to the inner sphere;   a plurality of first elements, seven in number, defined by a body with a substantially triangular plan view, with its curvo-concave sides having a projection in relation to its lower part, the upper central part of its three lateral projections presenting a recess in relation to which there is a lug projecting out that ends in a circular shape with its upper surface curvo-convex, while in the central part of its inner surface there is a cylindrical projection ending in a trunco-conical portion.   a plurality of second elements, twenty-four in number, defined by a body with a substantially triangular plan view, with two equal sides orthogonal to each other and the third side curvo-convex, the curvo-convex lateral side having a slot and the upper surface of the slot having a pair of small central projections which between them define a curvo-concave cavity;   a third unit element defined by a body with a substantially triangular plan view with its curvo-concave sides having a projection in relation to its lower part, its vertices having a recess in relation to which there is a lug projecting from the inside out, which ends in a circular shape with its outer surface curvo-convex, while in the central part of its inner surface there is a projection consisting of two independent and neighbouring rods which define a triangular section, one of the end sides of a rod ending in a projection with a triangular section.       
 
         [0013]    The three equal surfaces constituting the outer sphere have a substantially triangular plan view with two sides orthogonal and the third curvo-convex and the fourth side constituting the outer sphere has a substantially triangular plan view and the hole, of triangular section, passing through its central part, ends in separate recesses on its three sides. 
         [0014]    So, in the assembly of the first elements in the base body the trunco-conical portion fits via the openings defined between the concentric spheres, remaining positioned in the channell-shapped recesses materialised between them both. 
         [0015]    Moreover, in the assembly of the second elements, fitting into the slot of their curvo-convex side is the respective projection of the lateral lower part of one of the first elements, the inner surface of the second element remaining backed onto a surface relative to the outer sphere of the base body. 
         [0016]    Likewise, in the assembly of a second element with a first element, the respective lateral projection of the first element remains fitting between the pair of small central projections of the upper surface defined by a slot materialised in the curvo-convex side of the second element, acting as a brake and facilitating its static positioning. 
         [0017]    The closure of the toy is materialised, first, by fitting respective second elements into the projections of the lateral sides of the third unit element, and second, by fitting into the passing hole, of triangular section, of the larger size surface constituting the outer sphere of the base body, the projection consisting of the double rod, of similar general triangular section. 
         [0018]    So, the projection of triangular section in which ends one of the rods of the projection of the lower surface of the unit body of the third type fits into the respective recess in the passing hole of the base body, while the circular endings and curvo-convex outer surface of the projecting lugs, relative to the vertices of the third unit element, in their assembly, remain embedded in respective small depressions of the respective vertex of a first element backed on to it. 
         [0019]    In order to complement the description to be made forthwith, and with the aim of aiding a better understanding of the characteristics of the invention, this descriptive specification is accompanied by a set of drawings containing figures in which, on an illustrative rather than limiting basis, the most characteristic details of the invention are represented.

     DESCRIPTION OF A PREFERRED EMBODIMENT 
       [0035]    With the figures in view and according to the adopted numbering we can seen how the toy  1  consists of a plurality of pieces in accordance with three types of different elements
       which are mounted on a base body, representing an improvement on the toy claimed in Patent WO 2004/030776.       
 
         [0037]    So, the three-dimensional toy  1  comprises a base body  2  defined by two concentric spheres  3  and  4  sectioned, in the zone of separation between them, by three pairs of planes, the planes of each pair being parallel and the three pairs of planes being orthogonal to each other and decentred, as can be seen in  FIG. 1  of the designs. 
         [0038]    In this way, some openings  5  are created prolonged internally in some perimetric recesses defining some channell-shapped recesses  6  between the two spheres, with the imaginary outer sphere  4  consisting of four surfaces, three of those surfaces  7  being equal and of substantially triangular plan view with two sides orthogonal to each other and the other curvo-convex, while the fourth surface  8  that is defined has a substantially triangular plan view and is larger than the surfaces  7 . 
         [0039]    So, the surfaces  7  and  8  constituting the outer sphere remain attached to the inner sphere by respective attachment points  10  between which the channell-shapped recesses  6  have been defined. 
         [0040]    The surface  8  of larger size constituting the outer sphere  4  has in its central part a hole  9  of triangular section passing through to the opposite part of the inner sphere  3  and ending in separate recesses  26  in its three sides, as can be appreciated in  FIG. 3  of the designs. 
         [0041]    So, in the design of the puzzle, a diversity of elements are fitted into the base body  2  according to three different types, this diversity of elements having rotational movement according to different groups of elements. 
         [0042]    In this way, a plurality of first elements  11 , seven in number, are defined by a body of substantially triangular plan view with its curvo-concave sides provided in relation to its lower part with a projection  12 . 
         [0043]    Likewise, the projections  12  of the lateral sides of the first elements  11  have in their central part a recess  13  in relation to which it has projecting out from it a lug  14  ending in a circular shape with its upper surface curvo-convex. 
         [0044]    Likewise, in the central part of the inner surface the first elements  11  have a cylindrical projection  16  ending in a trunco-conical portion  15 . 
         [0045]    Equally, the toy  1  comprises a plurality of second elements  17 , twenty-four in number, which are defined by a substantially triangular plan view body with two sides equal and orthogonal to each other and the third side being curvo-convex, having a slot  18  in the lateral curvo-convex side and having in the upper surface of the slot  18  a pair of small central projections  19  between which is defined a cavity with a concave surface. 
         [0046]    Finally, the toy  1  comprises a third unit element  20  defined by a substantially triangular plan view body with its curvo-concave sides provided with a projection  21  in relation to its lower part, having a recess  25  in its vertices in relation to which it has respective lugs  22  projecting from the inside out, ending in a circular shape and with a curvo-convex outer surface. 
         [0047]    This third unit element  20  likewise has a projection  23  in the central part of its inner surface, this projection  23  consisting of two rods which define a substantially triangular section, with one of the rods being ended at its free end in a projection  24  of triangular section. 
         [0048]    Starting from this structuring in the assembly of the first elements  11  in the base body  2 , the trunco-conical portion  15  fits via the openings  5  defined between the concentric spheres  3  and  4 , remaining positioned in the channell-shapped recesses  6  materialised between the two spheres. 
         [0049]    Next, the assembly of the second elements  17  takes place, for which fitting into the slot  18  of its curvo-convex side is the respective projection  12  of the lower lateral part of one of the first elements  11  with the inner surface of the second element  17  being left backing on to a surface  7 - 8  relative to the outer sphere  4  of the base body  2 . 
         [0050]    So, in the assembly of a second element  17  with a first element  11 , the lug  14  projecting out from the respective side of the first element  11  fits between the pair of small central projections  19  of the upper surface defined by the slot  18  materialised in the curvo-convex side of the second element  17 , acting as a brake in the positioning of certain elements with respect to others. 
         [0051]    Finally, the closure of the toy is materialised, first, by fitting respective second elements  17  into the lateral projections  21  of the unit element  20 , and second, by fitting the projection  23  consisting of the two rods, of similar general triangular section, into the hole  9 , of triangular section, passing through the larger size surface constituting the outer sphere  4  of the base body  2 . 
         [0052]    Moreover, the circular endings and curvo-convex outer surface of the projecting lugs  22 , relative to the vertices of the third unit element  20 , in their assembly, remain embedded in respective small depressions  27  of the respective vertex of a first element  11  backed on to it. 
         [0053]    In  FIG. 14  of the designs it can be seen how the mounting is carried out of the various elements  11  of the first type and of the elements  17  of the second type on the base body  2 , and it can be seen how the trunco-conical portion  15  of the first type of element  11  remains embedded in the respective channel  6  defined between the spheres  3  and  4 . 
         [0054]    Likewise, it can be seen how the second type of elements  17  are assembled with the first type of elements  11  remaining with their inner surface backing on to one of the constituent surfaces  7  or  8  of the outer sphere. 
         [0055]    Equally, in  FIG. 15  of the designs we can see the different movements, by groups of elements, which will be able to be made once the toy has been mounted.
