DETAILED DESCRIPTION OF THE INVENTION

[0036] With reference to the various FIGS. 1 to 5, the innovative features of the magnetic toy block according to the invention will be now described with reference to a cube-shaped magnetic block, hereinafter also referred to as cubic block, shown in the aforementioned figures. The remaining FIGS. 6 to 11 show, still by way of non-limiting example, other possible shapes of magnetic blocks according lo the present invention.

[0037] As shown in the example of FIGS. 1 to 5, the magnetic block 10 comprises a hollow body of magnetically non-conductive material, for example of moulded plastics, or other material or combination of suitable materials for the prescribed use; the magnetic block 10 has peripheral walls having an outer peripheral surface to contact other magnetic blocks of a same or different type; in particular the block 10 comprises flat side walls 11, edges 12 and vertices 13 between contiguous side walls, as schematically shown. The walls of the block 10 preferably have a thickness ranging from 0.5 to 1.5 mm, to keep at minimum the loss of magnetic force of magnets, in an assembled condition of the blocks.

[0038] In FIGS. 2 and 3, the block 10 consists of two identically configured shell members 10A, 10B having male junction elements 14A and female junction elements 15A, respectively male junction elements 14B and female junction elements 15B configured for enabling a permanent press-fitting connection, or a connection of irreversible type.

[0039] In the case of FIG. 1 the cubic block 10 in comprises two shell members 10A, 10B each provided with three contiguous side walls 11.1, 11.2 and 11.3 having in common three edges 12 oriented at 90 to one another, and with respect to the three walls of the shell member which are converging on a vortex 13 of the same shell member (10A, 10B).

[0040] The male junction elements 14A, 14B and female junction elements 15A, 15B of each of the two shell members 10A and 10B extend inside the hollow body of the block 10 in a direction parallel to a reference axis, coinciding with a coupling direction of the two shell members; in the case of the cubic block in FIGS. 1-4, the male and female junction elements of the two shell members 10A, 10B extend parallel to a reference axis coinciding with an inner diagonal axis of the cubic block, extending between two opposite vertices 13.

[0041] There can be any number of male and female junction elements between the shell members of the block, with the junction elements arranged in any appropriate position provided that, in the assembled condition of the two shell members, each male element and each female element of one of the two shell members be axially aligned and press-fitted into or permanently connected to a corresponding female junction element, respectively into a corresponding male junction element of the other shell member, positioned at specific magnetic anchoring zones of the peripheral walls of the block.

[0042] In the case of the cubic block of FIGS. 1-4, each shell member 10A, 10B comprises a male junction element 14A, 14B that protrudes from a centre point of a respective edge 12, and a female junction element 15A, 15B that protrudes from a centre point of a respective wall 11 of the shell member.

[0043] In the case of FIGS. 2, 3 and 4, each edge 12 of the two shell members 10A, 10B thus comprises a sole male junction element 14A, 14B, whereas each wall 11 of the two shell members 10A, 10B comprises a sole female junction element 15A, 15B; nevertheless, the number and the position of the male and female junction elements 14 and 15 of the two shell members could be any, in relation to the geometric shape and dimensions of each block.

[0044] As previously mentioned, one of the features of the magnetic toy block according to the invention consists of identically configuring the two shell members 10A, 10B, each with a same number of male junction elements 14A, 14B and female junction elements 15A, 15B, which are identically positioned and aligned parallel to a reference axis of the hollow body, oriented in a coupling direction between the two shell members of the block; this allows a press-fitting of each male junction element 14A of one of the shell members into a corresponding female junction element of the other one of the shell members, keeping the male and female junction elements axially aligned each others during the assembling of the block.

[0045] As initially mentioned, the magnetic blocks of known type comprise one or more magnetic connection elements consisting of permanent magnets or ferromagnetic elements positioned in corresponding housing seats inside or outside the block.

[0046] Accordingly, a further innovative feature of the magnetic block according to the invention, in combination with the male and female coupling system, is shown in FIG. 5 where the same reference numbers of the preceding figures have been used to indicate similar or equivalent parts.

[0047] As shown from the detail of FIG. 5, the female junction element 15B of the shell member 10B, in addition to allow the press-fitting with the male junction element 14A of the shell member 10A, in synergy with the preceding coupling function performs a second function defining the housing seat for a magnetic connection element 16, to magnetically connect adjacent blocks of any toy assembly. Again, the magnetic connection element 16 can be a permanent magnet with the magnetic poles N and S suitably oriented or orientable with respect to a magnetic contact zone 10 of the walls, or coupling surfaces between blocks, or can be a ferromagnetic element.

[0048] The magnetic connection element 16, as shown with 16 in FIG. 8, is freely movable or rotatable housed in the female junction element 15B; in this manner, when two magnetic toy blocks are brought up against one another, the respective magnets 16 can move and rotate to automatically orient one of poles N or S of a magnet 16 of a block 10, towards a pole S or N of opposite polarity of magnet 16, or towards a ferromagnetic element of the other block 16, during the construction of an assembly.

[0049] Alternatively or in combination with freely movable magnetic connection elements, it is possible to provide an arrangement in a fixed manner, without any possibility of the magnetic connection elements to move or rotate, for example by configuring the male junction element 14A of a shell member to extend up to a short space from the bottom end of the female element 15B, that is the inner surface of the side wall of the other one of the shell members, to prevent any movement of the magnet 16 or ferromagnetic element previously threaded into the female element 15B.

[0050] The male junction elements 14A, 14B and the female junction elements 15A, 158 can be configured in any manner provided that they are suitable for permitting their press-fitting. In the case shown, both male junction elements and female both junction elements have a circular cross section; the outer diameter of the male junction element is slightly greater than the inner diameter of the female junction element to fixedly press-fitting the male and female junction elements in an assembled condition of the block. Nevertheless, alternatively to the circular cross section, the male and female junction elements could have any other shape, other than that shown, for example they could have square cross section or could be configured with ribs and/or longitudinal slots, provided that they are suitable for permitting an irreversible press-fitting or coupling with slight interference thereof.

[0051] In FIGS. 1 to 5, a cubic magnetic block has been shown; nevertheless, although the general features of the present invention remain the same, the magnetic block could have any other geometrical shape, for example it could consist of a hollow body of a polyhedron shape having a number of flat walls, or otherwise shaped walls, or a spherical, ovoid, cylindrical or prismatic shape, provided that it consists of two identically configured shell elements having an identical number of male junction elements and of female junction elements for blocks of a toy assembly.

[0052] Some embodiments are shown in FIGS. 6 to 11 of the attached drawings, in which the same reference numbers as for the preceding figures have been used again to indicate similar or equivalent parts.

[0053] In particular, FIGS. 6 and 7 show a magnetic octahedron-shaped block, having a hollow body consisting again of two identically shaped shell members 10A, 10B, each provided with a sole male junction element 14A, 14B and with a sole female junction element 15A, 15B axially aligned and protruding inside from the inner surface of respective side walls, and configured for housing a permanent magnet 16 or a ferromagnetic element as previously mentioned.

[0054] FIG. 8 shows, still by way of example, a possible variation of the shell members of the tetrahedron of FIG. 6, in particular the shell member 10B. In the case of FIGS. 6 and 7, one male and one female junction element is positioned at respective opposite side walls of the two shell members; otherwise, in the case of FIG. 8 each shell member comprises two male junction elements 14B on two opposite side walls of the octahedron, and comprises two female junction elements 15A, 15B on the other opposite side walls. Thus, during the assembling of the two shell members 10A, 10B it will be necessary to rotate one shell member with respect to the other one, according to a reference axis parallel to the junction elements, so as to orient and align each male junction element and each female junction element of one of the two shell members, with a corresponding female junction elements, respectively with a corresponding male junction elements of the other shell member.

[0055] FIGS. 9 and 10 show on the other hand a magnetic block according to the invention having a hollow body of spherical shape. Again, the two hemispherical shell members 10A and 10B are identically configured with male junction elements 14A, 14B and female junction elements 15A, 15B for housing magnets 16 or ferromagnetic elements, in which the male and female junction elements of a shell member in an assembled condition are axially aligned and press-fitted into the female junction elements, respectively male junction elements of the other shell member of the block.

[0056] FIG. 11 shows a possible embodiment of the hemispherical shell members 10A and 10B, in which two male junction elements 14B are positioned at a first diametric direction of the shell member, whereas two female junction elements 15B are positioned at a second diametric direction of the shell member, orthogonal to the preceding diametric direction.

[0057] In all cases, the number and the position of the male junction elements and of the female junction elements can vary and differ from what has been shown, always maintaining an identical configuration of the two shell members, in combination with the housing of the magnetic connection elements 16, selectively arrangeable in one or more female junction elements of one or both shell members of the block, at the assembling.

[0058] FIG. 12 lastly shows a toy assembly of a kit for a composition of magnetic toy blocks according to the invention, magnetically coupled so as to imitate an animal; in particular the composition of FIG. 12 comprises a plurality of toy blocks of cubic shape 110, imitating the body of the animal, a first spherical block 210 imitating the nose and a second spherical block 210 imitating the tail, whereas two octahedron-shaped blocks 310 are positioned to imitate the ears; obviously by differently combining and assembling magnetic blocks of different shapes or types, it is possible to make any composition.

[0059] The single magnetic blocks can be optionally provided with decorative elements on the external surface thereof such as letters, numbers, figures and/or differently coloured parts, so as to stimulate creativity and the use of the blocks in making up any sort of toy assembly.

[0060] In all the cases, from what has been illustrated and described, it is clear that numerous economic and productive advantages are obtained by a magnetic toy block according to the invention, compared to conventional toy blocks. In fact, the magnetic block according to the invention, consisting of two identically shaped shell members, provided with male and female junction elements configured for a press-fitting and housing permanent magnets and/or ferromagnetic elements, or equivalent magnetic connection elements, can be produced in a simpler and cheaper way, both from investments and production point of view and of assembly times, in an easily automatable manner.

[0061] In fact, in the case of blocks obtained by moulding of plastics, it is possible to use a sole type of mould, configured with one or more moulding cavities of the same type, corresponding to the shape of the two shell members of the block; this allows the use of a cheaper mould, having a pluralities of moulding cavities per surface unit of the mould, greater moulding speed and productivity; the structural simplicity of the mould, due to the identical configuration of the two shell members of each single magnetic block, lastly facilitates automation of the assembling operations.

[0062] The disposition of the magnet and/or ferromagnetic elements inside the female junction elements according to the present invention, besides being a distinguishing and an innovative feature, compared to the known prior art, may be advantageously used with magnetic toy blocks having planar peripheral walls, in particular with a cube shaped magnetic toy block. The solution according to the present invention provides the advantage of positioning the magnet and/or ferromagnetic elements at a center point of each peripheral wall, avoiding the use of separate elements to assemble the shell members of the block, in which the use of separate assembling elements requires more complex time-consuming assembling operations, involving additional costs.

[0063] Furthermore, the magnetic block according to the present invention improves the playability, during the construction of a toy assembly, by automatically allowing a centered disposition of each toy block in the assembled condition of the toy blocks.
