Magnet assembly for magnetic toys {MAGNET ASSEMBLY FOR MAGNETIC TOY}

The present invention relates to a magnet assembly for a magnetic toy, and more particularly, to a magnetic toy in which a permanent magnet is embedded in each side of a magnetic toy in the form of a block so that each block can be mutually coupled regardless of the polarity of the magnet. It relates to a magnet assembly.

In general, magnetic toys containing permanent magnets combine magnets with linear, panel-type or block-type unit constituent members, and then use the magnetic force of the magnets to form three-dimensional solids having predetermined shapes. It is configured so that it can be assembled into a structure.

As an example of the magnetic toy, there is a block-type magnet toy made of a hexahedron made of wood or plastic. It is configured to be able to assemble a three-dimensional three-dimensional structure having a predetermined shape through surface coupling between block-type magnetic toys.

At this time, when the permanent magnet is fixed to the surface of the block and its polarity is the same in relation to the permanent magnet fixed to the other unit block coupled thereto, a repulsive force, not an attractive force, is generated so that the unit block members are coupled together. This becomes impossible, and assembling between the unit block members must be performed while checking the polarity, a problem in which the freedom of assembly is reduced occurs.

In order to solve this problem, as shown in FIG. 1, Korean Patent Registration No. 10-1600529 discloses "a cylindrical insertion part formed inside and a diameter smaller than the diameter of the insertion part formed on one side of the insertion part.

Sphere 100 is disclosed.

However, in the above-described 'magnet mounting tool for magnetic toys', when the magnet polarity of the blocks that are coupled to each other in contact with each other in the block type magnetic toy generates a repulsive force rather than an attractive force, making it impossible to combine unit block members. has been solved, but since the magnet mounting hole 100 is composed of a plurality of parts having a complicated structure, and a predetermined hole must be drilled in the permanent magnet in order to manufacture a smooth product, there are many problems in manufacturing and assembling parts. As time and money are consumed, a problem of low economic feasibility has occurred.

Accordingly, as shown in FIG. 9 , the magnet assembly buried and installed on each surface of the plurality of blocks 50 through the adsorption force of the permanent magnet 40 embedded in the housing 10 via the rotating member 30 With the surfaces of a plurality of blocks 50 attached to each other, it is possible to manufacture three-dimensional structures of various shapes.

In addition, when a rotational force is applied in different directions in a state in which a pair of blocks 50 are held in both hands, respectively, a pair of rotation members 30 in which the through holes 34 and the protrusions 36 are engaged so as to correspond to each other. ) performs a bearing function, respectively, and the rotation of the block 50 is performed, and at this time, the toothed parts 16 formed and engaged with the pair of housings 10 generate a sound effect of can arouse interest.

After that, as an external force of a certain strength or higher is applied to the plurality of mutually coupled blocks 50, the mutual adsorption force of the permanent magnets 40 is released and can be easily separated into each block 50 again. .

In another embodiment of the present invention shown in FIGS. 10 and 11, a pair of blocks with magnet assemblies embedded in each surface are housed in the housing 10 of each block via the rotating member 30, and permanent magnets (40) allows them to be mutually adsorbed.

That is, as the predetermined surfaces of the pair of blocks come into contact with each other, a pulling force is generated between the permanent magnets 40 embedded in the rotating member 30 of each magnet assembly that are in contact with each other. .

Accordingly, the permanent magnets 40 movably accommodated in the rotating member 30 of each housing 10 are moved to the rear wall side of the front surface of the rotating member 30 to come into close contact with each other, and the permanent magnets provided in each magnet assembly ( 40) has different polarities, that is, solid adsorption is achieved in a state where the "N" pole and the "S" pole of one side and the other side face each other.

At this time, through mutual engagement of the plurality of through holes 34 and protrusions 36 formed in the rotation member 30 provided in each magnet assembly, the pair of blocks can maintain a very firm adsorption state. .

In addition, in the state of adsorption of the pair of blocks, when the rotational force is applied in different directions while holding the pair of blocks in both hands, the through-holes 34 and the protrusions 36 are firmly matched to each other. While the pair of interlocking rotating members 30 each perform a bearing function, the pair of blocks can be smoothly rotated in opposite directions while being guided by the toothed portion 16 of the housing 10.
