• the complementary block members can have any geometrical shape having flat or shaped coupling surfaces which match with the coupling surfaces of one or more types of basic block members of the set according to the invention.
• the basic block members can have a modular dimension, or be a multiple of a modular dimension, for example ranging from 5 to 10 cm or more to be eas- ily grasped by the hands.

• the flat coupling surface 12 of each face of the cube completely surrounds a concave shaped coupling surface 13, in the form of a spherical cap; from figures 1 and 2 it can also be seen that the shaped surfaces 13, belonging to two opposite faces of the cube, are axially aligned with one another.
• a cube-shaped basic block member 10.1 is shown; however, as mentioned previously, the basic block member 10 can be of any geometrical shape, having completely flat lateral faces or provided with flat coupling surfaces 12 in combination with concave and/or convex shaped coupling surfaces 13, which extend from one or from both sides of the flat coupling sur- faces of each face of the block member 10.1.
• the basic block member 10.1 is also provided with a system of magnetic elements, variously disposed and housed in corresponding seats inside the hollow body 18 of the basic block member, close to the wall surfaces to generate magnetic attraction and/or repulsion forces with respect to magnetic elements inside other basic block members 10 and/or complementary block members 11 in an assembled condition as shown further on.
• the hollow body 18 of the block member 10.1 comprises internal seats 15 for housing a magnetic or magnetisable element 14 for anchoring to other blocks;
• the magnetic anchoring element 14 can either be a ferromagnetic material which is magnetisable by induction, or preferably a permanent magnet, for example in the form of a disk or a small cylinder having opposite polarities N and S on two opposite faces according to its longitudinal axis.
• the magnetic element 14 can be fixedly housed in its seat 15 or freely movable, as shown, with the possibility to rotate around itself and in space, to automatically orientate any one of the two N and S polar faces towards the coupling wall surface 13, depending upon the polarity of the magnet of another block member 10 or 11 brought into contact; in this connection, it is necessary to point out that the space between the seats housing the magnets must be such as to prevent a reciprocal influence between magnets belonging to a same block.
• Figure 3 shows a second basic block member 10.2, multiple of the basic block member 10.1 of figure 1 ; therefore in figure 3 the same reference numbers of figure 1 have been used to indicate similar or equivalent parts.
• the basic block member 10.2 comprises a hollow body 18 having on each lateral face, or part thereof, at least one flat coupling surface 12, and one or more shaped coupling surfaces 13, two in the case shown.
• the hollow body 18 of the block member 10.2, in correspondence with the shaped coupling surfaces 13, will have internal seats for housing magnetic elements, in a way wholly similar to that shown in the cross-section of figure 2; here again, all the magnetic elements of the block member 10.2, or part thereof, may comprises a permanent magnet, or a ferromagnetic element.
• Figures 4 and 5 show the example of a third basic block member 10.3, again comprising a hollow body 18 of a substantially cubic shape, like the example of figures 1 and 2; therefore the same reference numbers have been used to indicate similar or equivalent parts.
• the example of figures 4 and 5 differs from the example of figures 1 and 2 as far as one of the shaped coupling surfaces is concerned.

• shape and/or dimensions of the basic block members 10 can vary and be of any type, for example of prismatic or polyhedral type or of any other geometrical shape, provided that part or all of the lateral faces comprises the combination of at least one flat coupling surface, and at least one concave and/or convex or differently shaped coupling surface, according to need.
• the form of the shaped coupling surfaces can also be of any kind, other than the cap of the previous figures. It is also pointed out that one or more basic block members 10 of the set may have shaped coupling surfaces of a same type on all or part of their lateral faces; likewise, the basic block members may have shaped coupling faces of different types, concave and/or convex, in any way disposed and/or combined in a same block. As mentioned previously, this invention also comprises the case in which a basic block member has one or more lateral faces having a flat coupling surface which extends over the entire face.
• Figures 6 and 7 show a first type of a complementary block member 11 magnetically anchorable to one or two basic block members of a same or different types, or to other complementary block members of different shapes.
• the complementary block member 11.1 comprises a disk-shaped hollow body 16 having an annular flat surfaces 17' on peripheral edges; the body 16 on the two lateral faces is provided with a convex shaped coupling surface 17, for example in the form of a spherical cap coaxially arranged to annular surface 17', which perfectly matches with a concave coupling surface 13 of a basic block member 10.
• the latter also comprise magnetic elements which can consist either of permanent magnets or of ferromagnetic elements, magnetisable by induction by a magnet of another block member closely brought in contact to the previous one.
• the magnetic elements can be shaped and disposed in any way in the hollow body 16 of the complementary block member 11 , and in any number in relation to the shape and dimensions of the block itself, or for other specific requirements.
• the complementary block member 11.1 comprises, for example, a first disk-shaped magnet 14, or of any other suitable shape, housed in an internal seat 15 close to a wall surface, in a way similar to the magnets 14 of the basic block members 10.
• the complementary block member 11.1 can comprise an elon- gated magnet 20 of another type, for example in the form of a cylinder to allow the magnetic anchorage to other blocks by the same magnet 20 in at least two diametrically opposite points, or in several angularly spaced apart points along the cylindrical wall surface of the hollow body 16.
• the magnet 20 is in the form of a bar or elongated magnetic element, for example of cylindrical shape, which extends diametrically for a length equivalent to or slightly smaller than the internal diameter of the hollow body 16, so as to enable a simultaneous coupling in two diametrically opposite points, and rotate.
• the latter could be of any geometrical shape, of such kind as to allow a magnetic anchorage in a plurality of points of the cylindrical surface; for example it could be cross-shaped or star-shaped, suitable for allowing the magnetic coupling to other block members in several angularly spaced apart points of the cylindrical wall surface of the body 16.
• the magnetic element 20 can also consist of a single magnet, or one or more magnets having magnetic poles in contact with a ferromagnetic core element suitable for conducting the flux; for example may comprise an intermediate ferromagnetic core between two magnets, or in the form of a polar extension at one end of a magnet; other possible conformations of the magnetic element 20 cannot be excluded.
• the magnet 20 lies in a plane at right angles to the central axis of the block member 11.1 ; consequently the magnet 20 can be fixedly housed in the hollow body 16, without any possibility of moving, or angularly rotatable according to said central axis.
• the angular rotation of the magnet 20 can take place along a pre-established ach of a circle, providing suitable stop means inside the body, or the magnet 20 can be freely rotatable by 360° in both rotational directions.
• Figures 8 and 9 show a second complementary block member 11.2, also disk-shaped, which differs from the block member 11.1 of the previous figures due to a different disposition of the magnetic anchoring elements 14 and 20.
• the same reference numbers of figures 6 and 7 have been used to indicate similar or equivalent parts.
• the solution of figures 8 and 9 differs from the solution of figures 6 and 7 in that now two or more magnets 14 are disposed in their respective seats 15 peripherally and in angularly spaced apart positions along the cylindrical wall of the hollow body 16.
• the magnet 20 is disposed in a respective seat 21 which extends, coaxially to the body 16, between the two convex coupling surfaces 17.
• the length of the magnet 20 can be equivalent to that of the seat 21 to enable it to be fixedly housed, without any possibility of movement; alternatively, the magnet 20 can be shorter in length than the seat 21 , to allow it to perform a certain axial movement.
• peripheral seats 15 can angularly extend along a certain ach of a circle, for example along an ach of 90°, more or less, in relation to the number of magnets 14 used or other requirements. In any case, adjacent seats 15 must be spaced apart from one another by an angle sufficient to prevent any influence or interference between magnets of the block.
• disk-like complementary block members 11.1 and 11.2 having a circular shape; however, other possible disk-shapes for the complementary block member 11 cannot be excluded; for example, the body 16 could have the shape of a polygonal disk. Consequently, for the purposes of this description, the term "disk-shaped" is understood to mean a substantially flat body having circular or polygonal peripheral walls tangent to a reference circle.
• Figures 12 and 13 show the solution of a third complementary block member 11.3; also in the case of figures 12 and 13, the same reference numbers of the previous figures have been used to indicate similar or equivalent parts.
• the block member 11.3 comprises a semi-spherical hollow body 16, having a first flat coupling surface 22, forming the base of the semi- sphere, and a second semi-spherical coupling surface 23.

• the block member 11.3 also comprises a central magnet 20 of elongated shape, housed in a seat 21 which axially extends between the two coupling surfaces 22 and 23.
• Figures 14, 15 and 16 show the solution of a fourth complementary block member again of a semi-spherical shape; consequently, also in this case the same reference numbers of figures 12 and 13 have been used to indicate similar or equivalent parts.
• the semi-spherical block member 11.4 of figures 14, 15 and 16 differs from the semi-spherical block 11.3 of figures 12 and 13 exclusively due to the fact of comprising a magnet 14 housed in its respective seat 15, centrally arranged to the flat coupling surface 22 and to the spherical coupling surface 23, in place of the single elongated magnet 20 of the previous example.
• the magnets 14 can be fixed or freely movable and/or may ro- tate in their housing seat under the effect of external magnetic fields.
• Figures 17, 18 and 19 show the solution of a fifth complementary block member 11.5 in the shape of a sphere; here too, the same reference number of the previous figures have been used to indicate similar or equivalent parts.
• the complementary block member 11.5 comprises a hollow body 16 having a plurality of seats 15 for housing an equivalent number of magnets 14.
• the spherical block member 11.5 comprises eight seats 15 for a corresponding number of magnets 14, disposed in angularly spaced apart positions along two different meridian lines; however, the number of magnets 14 and/or their disposition could be any, always maintaining an angular space between seats 15 of such length as to prevent any interference between adjacent magnets.
• Figures 20, 21 and 22 show the solution of a sixth complementary block member 11.6 of cylindrical shape, in some ways similar to the disk-shape of the complementary block member 11.1 of figures 6 and 7; consequently, also in this case the same reference numbers have been used to indicate similar or equivalent parts.
• the block member 11.6 also comprises a hollow body 16 delimited by a cylindrical peripheral surface, which axially extends between two flat wall sur- faces 25 and 26 on the lateral faces of the cylinder. Magnets 14 are housed fixedly or freely movable in respective seats 15 inside the hollow body 16, in central positions axially aligned with the body 16.
• an elongated magnet for example in the form of a bar 20 is disposed to diametrically extend to the peripheral wall of the body 16; once again, the magnet 20 can freely rotate by an angle ranging from 0° to 360°, or fixedly housed.
• Figures 23 and 24 show the solution of a seventh complementary block member 11.7, also of cylindrical shape; consequently, the same reference num- bers have been used again to indicate similar or equivalent parts for the hollow body 16, the magnets 14 with their respective seats 15; in that case the magnet

• the assembly of figure 25 comprises two basic cube-shaped block members 10.1 , disposed one on top of the other, with the interposition of a spherical block member 11.5 magnetically anchored to the basic block members 10.1.

• magnetically anchored on one side of the lower cubic block member 10.1 is a composition comprising two semi- spherical block members 11.3 and an intermediate cylindrical block member
• the assembly could be implemented by adding other basic and/or complementary block members of a same or of different types, variously positioned in relation to one another; a characteristic common to all the possible assem- blies, deriving from the features of each individual block member, or from the presence of several coupling surfaces and of several magnetic anchoring elements, consists in the possibility of moving and/or differently orienting the block members of the assembly in relation to one another, in order to change the shape and characteristics of the construction. This stimulates creativity and promotes useful learning of different geometrical shapes and of certain basic principles of magnetism.

• the auxiliary block comprises a hollow body 41 , having a seat 46 for a semi-spherical complementary block mem- ber 11.3, to complete the crab.
• the auxiliary block member 40.4 also comprises a magnetic element 14 for anchoring with a magnet 20, or 14 (not shown), of the complementary block member 11.3.
• the basic block members 10 and the complementary block members 11 can be of any desired shape, provided it is suitable for allowing the reciprocal magnetic anchorage between corresponding flat and/or shaped coupling surfaces.
• the invention also comprises auxiliary block members 40 for decorative purposes, appropriately shaped to imitate animals, dolls, living creatures or ob- jects and/or imaginary creatures, provided with suitable magnetic and/or mechanical anchoring means for anchoring to basic and/or complementary block members.
