Definitions
- the present invention relates to an accessory for magnetic construction games, and in particular to an accessory which allows the mutual movement of one or more member groups of a magnetic construction game.
- WO 99/60583 discloses a magnetic construction game comprising a plurality of magnetic bars suitable for being mutually joined by means of ferromagnetic spheres so as to made up a complex structure.
- WO 02/055168 and WO 02/076565 disclose instead some accessories for said magnetic game, which serve for reinforcing the joining between the magnetic bars and the ferromagnetic spheres.
- the structure made up of the magnetic bars, the ferromagnetic spheres and the relevant accessories is substantially static, i.e. does not allow a smooth mutual movement of the members, so that the user's fun is limited with respect to other construction games of the dynamic kind.
- the accessory according to the present invention can be inserted into a complex structure of the magnetic game for allowing the mutual movement of some parts thereof, so that this structure is not static but dynamic.
- the accessory according to the present invention can be added to a known magnetic game without any modification of the existing members nor aesthetic or modularity problems.
- the accessory according to the present invention can be employed not only for the mutual movement of the parts of a composite structure, but also as a skate, so that this structure can slide on any surface.
- FIG. 1 shows a side view of a first embodiment of the accessory according to the present invention
- figure 2 shows a top view of the accessory of figure 1;
- figure 3 shows a side cross-sectioned view along plane III-III of the accessory of figure 1;
- FIG. 4 shows a side view of a second embodiment of the accessory according to the present invention.
- figure 5 shows a top view of the accessory of figure 4.
- the accessory according to the first embodiment of the invention comprises two ferromagnetic members 1, 2 having a substantially spherical shape in which a diametral hole, i.e. passing through the center, is made.
- a pin 3 (shown with broken lines in figure 2) is inserted into said diametral holes so that the ferromagnetic members 1, 2 can rotate in an independent manner around its longitudinal axis A in the direction indicated by the arrows of figure 1.
- Known magnetic bars 4 can thus be applied to any point of the surface of the ferromagnetic members 1, 2, so as to allow the rotation of said bars around axes A.
- the outer diameter d of the ferromagnetic members 1, 2 is substantially equal to the diameter, in particular comprised between 12 and 13 mm, of the known ferromagnetic spheres 5, which can be in turn applied to the free ends of bars 4.
- the distance D between the ferromagnetic members 1, 2 is substantially equal to the length of the magnetic bars 4, in particular comprised between 14 and 16 mm or between 25 and 27 mm.
- Pin 3 is made of steel or brass, while the ferromagnetic members 1, 2 are made of steel, with a high percentage of ferrite.
- the two pins 3 of the ferromagnetic members 1, 2 are suitably arranged between two plates 6, 7 having an elongated shape, which are substantially perpendicular to axis A, so as to made up a skate having the ferromagnetic members 1, 2 as wheels.
- Plates 6, 7 are mutually connected by at least one bridge 8 which is arranged between the ferromagnetic members 1, 2 and has the upper surface preferably lying on a plane B aligned with the upper ends of the ferromagnetic members 1, 2.
- Plates 6, 7 are further provided with folds 9, so that their central lateral surface lies on a plane C aligned with the lateral ends of the ferromagnetic members 1, 2.
- Plates 6, 7 and bridge 8 are made of a single piece of a ferromagnetic material, so that the magnetic bars 4 can be applied to their outer surfaces.
- the accessory according to the second embodiment of the invention comprises, as in the first embodiment, two plates 6, 7, which are however longer, so as to pivot three of more ferromagnetic members having a spherical shape, between which two or more bridges 8 are arranged.
- the present embodiment comprises two pairs of members having a substantially hemispherical shape 10, 11 and 12, 13 with the circular plane surfaces arranged side by side, instead of two ferromagnetic members having a spherical shape arranged at the ends of plates 6, 7.
- Each of these hemispherical ferromagnetic members 10, 11, 12, 13 can rotate in an independent manner around the longitudinal axis of pins 3 inserted into corresponding axial holes, i.e. perpendicular to the center of their circular plane surfaces.
- the outer diameter d of the ferromagnetic members 10, 11, 12, 13 is substantially equal to the diameter, in particular comprised between 12 and 13 mm, of the ferromagnetic spheres 5.
- the number of the ferromagnetic members having a substantially spherical or hemispherical shape may vary according to the kind of connection desired in the resulting structure.
