Description

  The present invention relates to a structure for coupling at least two magnetic induction tables each having a magnetic shielding circuit formed by adsorbing a magnetic metal plate to a magnet, and a play equipment using the coupling structure of the magnetic induction tables.

The present applicant, as a play equipment using this type of magnetic induction table, arranged a plurality of magnets in parallel so that the magnetic poles face the same direction, and attracted a common magnetic metal plate to each magnet, thereby magnetic induction. A proposal has been proposed in which the stage area of the platform is increased to increase the degree of freedom of the structure (see, for example, Patent Document 1).
JP-A-10-52577

  By the way, in the play equipment using the conventional magnetic induction table, although the stage area of the magnetic metal plate can be increased, it is necessary to manufacture a plurality of types of magnetic induction tables having sizes according to the application. Inventory management is complicated and disadvantageous in terms of cost. The Applicant is considering providing more complex and difficult products from the viewpoint of developing children's creativity and expressive power. For this purpose, it is necessary to manufacture a magnetic induction table having a larger size, and there is a concern that the commercial price will rise.

  In order to avoid such a concern, it is effective to create an arbitrary stage area by coupling magnetic induction tables having the same size and dimensions to each other.

  In this case, as shown in FIG. 5, when the two magnetic induction tables 30, 30 are arranged in parallel so that the magnetic poles (N pole, S pole) of the magnets 31, 31 are opposite to each other, the magnetic metal is caused by the mutual magnetic force. The plates 32, 32 are easily adsorbed and bonded together. However, in this case, for example, if the first-stage magnetic chips 33 and 33 adsorbed on each magnetic metal plate 32 are adsorbed by the second-stage magnetic chip 34, a magnetic closed circuit circuit is formed. Is formed, and the magnetic chip 34 is not attracted to the second-stage magnetic chip 34 and cannot be stacked in multiple stages.

  On the other hand, as shown in FIG. 6, when the magnetic induction tables 30 and 30 are arranged in parallel so that the magnetic poles (N poles) of the magnets 31 and 31 face the same direction, a closed magnetic circuit is not formed. Therefore, the magnetic chips 35 and 36 can be stacked in multiple stages on the second-stage magnetic chip 34. However, if the magnetic poles of the magnets 31 are in the same direction, the magnets 31 and 31 repel each other strongly, so that the magnets 31 and 31 cannot be coupled.

  The present invention has been made in view of the above-described conventional situation, and provides a magnetic induction base coupling structure capable of coupling magnetic induction bases without forming a closed magnetic circuit, and a play equipment using the same. The challenge is to do.

  The invention of claim 1 is a structure for coupling at least two magnetic induction bases each having a magnetic shielding circuit formed by adsorbing a magnetic metal plate to a magnet, wherein each magnetic induction base is connected to each magnet. The magnetic metal plates are arranged in parallel so that the magnetic poles face in the same direction, and the magnetic metal plates are coupled with a magnetic material interposed therebetween.

  According to a second aspect of the present invention, there is provided a play equipment using the magnetic induction table coupling structure according to the first aspect.

  According to a third aspect of the present invention, in the play equipment according to the second aspect, a large number of magnetic chips are attracted to the magnetic metal plate so as to be stacked.

  According to the coupling structure of the magnetic induction table according to the invention of claim 1, the magnets of at least two magnetic induction tables are arranged in parallel so that the magnetic poles are directed in the same direction, and the magnetic metal plates are interposed between the magnetic materials. Since they are coupled, the magnetic body absorbs the magnetic force of each magnet to form one magnet, and the magnetic metal plates can be adsorbed with the magnetic poles oriented in the same direction. As a result, it is possible to couple the magnetic induction tables without forming a closed magnetic circuit. As a result, an arbitrary stage area can be formed simply by manufacturing a magnetic induction table having the same size and dimensions, compared with the case of manufacturing multiple types of magnetic induction tables with different sizes. Inventory management is facilitated, and as a result, costs can be reduced.

According to the play equipment according to the invention of claim 2, since the magnetic induction tables are coupled so as to have the same polarity, the stage area can be arbitrarily set, and as a result, it is complicated and sophisticated according to the growth of the child. Creation of a structure becomes possible.
In addition, since the application of the magnetic induction table can be expanded, it can be developed as a product for adults such as a hobby craft, a three-dimensional model, and a decoration board.

  In the invention of claim 3, since the magnetic chips are attracted to each magnetic metal plate so as to be stacked, the magnetic chips can be stacked in any number of stages on an arbitrarily set stage, and the demand as a play equipment Can be expanded.

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.
FIG. 1 and FIG. 2 are diagrams for explaining a magnetic induction table coupling structure and a play equipment using the same according to an embodiment of the present invention, and FIG. 2 is a diagram schematically showing the coupling process of the magnetic induction table.

  In the figure, reference numeral 1 denotes a play equipment, which is a combination of a large number of magnetic chips 3, 4 and 5 stacked on two magnetic induction bases 2 and 2 coupled so as to be flush with each other. Thus, a three-dimensional structure is constructed. Through this kind of puzzle-like play, the children's imagination and expressive power can be enhanced to increase their creative motivation and to bring out their potential.

  Each of the magnetic chips 3 to 5 is formed of a person, an animal, various tools, etc., and these surfaces are colored to enhance the appearance.

  Each magnetic induction table 2 has the same size, size and shape, and magnetic metal plates 8 each having a square shape in both poles (N pole, S pole) of magnets 7 and 7 having a cylindrical shape or a prismatic shape, etc. By adsorbing 8, a magnetic shielding circuit is formed. Here, the magnetic metal plate 8 may be arranged only for the N pole of the magnet 7.

  Each magnet 7 is made of, for example, a magnetic force of about 1400 G, and each magnetic metal plate 8 is made of iron, nickel, cobalt, or an alloy thereof.

  The magnetic induction bases 2 are arranged in parallel so that the magnetic poles (N poles) of the magnets 7 face the same direction, and the magnetic metal plates 8 of the magnetic induction bases 2 are thin plate-like magnetic bodies 9. Are connected to each other. The magnetic body 9 is made of the same metal material as that of the magnetic metal plate 8, is disposed so as to cover the side end surface of the magnetic induction table 2, and is formed so as to be flush with each magnetic metal plate 8.

The coupling process of the magnetic induction tables 2 and 2 will be described in detail.
First, when the magnetic induction table 2 is a single unit, a magnetic shielding circuit is formed by the upper and lower magnetic metal plates 8. For example, as shown in the magnetic induction table 2 ′ on the right side of FIG. 2A, the magnetic line of force a of the magnet 7 passes through the upper magnetic metal plate 8, and from the outer edges 8a, 8a of the magnetic metal plate 8 to the lower side. Flows into the magnetic metal plate 8. At this time, the lines of magnetic force emitted from the outer edges 8a and 8b are equivalent.

  When the magnetic body 9 is brought into contact with the side end surfaces of the upper and lower magnetic metal plates 8, 8 on the left (left side) magnetic induction table 2, a part b of the magnetic field lines a passes through the magnetic body 9 and the remaining magnetic field lines. c flows outside the magnetic body 9. (See FIG. 2 (a)). The magnetic force flowing outside is about 1/3.

  In this state, when the other (right side) magnetic induction table 2 ′ is brought close to one magnetic induction table 2, the magnetic field lines c passing outside the magnetic body 9 are pushed by the magnetic field lines a of the other magnetic induction table 2 ′. In addition, they repel each other and the peaks of both magnetic lines of force a and c gradually become smaller (see FIG. 2B).

  When the other magnetic induction table 2 'is brought closer, the magnetic field line c passing outside the magnetic body 9 and the magnetic field line a of the other magnetic induction table 2' are absorbed by the magnetic body 9 and gradually decrease and repel each other. On the contrary, they start to adsorb each other (see FIG. 2C).

  When the magnetic metal plate 8 of the other magnetic induction base 2 'is brought into contact with the magnetic body 9, the magnetic lines c and a of both 2 and 2' are confined in the magnetic body 9, and the magnetic body 9 is It becomes a magnet (see FIG. 2D). In this way, the adjacent upper and lower magnetic metal plates 8 and 8 are adsorbed and combined by the magnetic force of the magnetic body 9. 2A to 2D, the numbers in the circles indicate the number of lines of magnetic force that emerge from the left and right outer edges 8a and 8b of the upper magnetic metal plate 8.

  As described above, according to the present embodiment, the magnets 7 of the pair of magnetic induction tables 2 are arranged in parallel so that the magnetic poles face the same direction, and the adjacent upper and lower magnetic metal plates 8 are interposed between the magnetic bodies 9. Thus, the magnetic body 9 becomes one magnet, and the magnetic metal plates 8 are attracted to each other with the magnetic poles directed in the same direction. As a result, the magnetic induction tables 2 can be coupled to each other without forming a closed magnetic circuit. Thus, an arbitrary stage area can be formed simply by manufacturing a standard size magnetic induction table 2 having the same size, size and shape, and a plurality of types of magnetic induction tables having different sizes are manufactured. Compared with, production management and inventory management become easier, and as a result, costs can be reduced.

  In this embodiment, since the magnetic induction tables 2 can be coupled to form the same pole, the stage area can be arbitrarily set, and the creation of a complex and difficult structure according to the growth of the child Is possible.

  In this embodiment, each magnetic metal plate 8 can be attracted so that a large number of magnetic chips 3 to 5 are stacked, so that the magnetic chips 3 to 5 can be stacked in multiple stages in a free form, Demand can be expanded.

  Thus, since the application of the magnetic induction table 2 can be expanded, it can be developed as a product for adults such as a hobby craft, a three-dimensional model, and a decoration board.

  In the present embodiment, the case where the two magnetic induction tables 2 are coupled has been described. However, in the present invention, the number of coupling of the magnetic induction tables can be freely set. For example, as shown in FIG. 3, the magnetic derivatives 2 can be coupled in a row, or the magnetic induction table 2 can be coupled in a lattice shape as shown in FIG. In either case, the magnetic induction tables 2 can be easily combined by coupling the magnetic induction tables 2 with the magnetic body 9 interposed therebetween. In this way, it can be used as, for example, a shogi board or a go board.

  In the above embodiment, the play equipment has been described as an example. However, the use of the magnetic induction table of the present invention is not limited to this. For example, it can be used as a learning material or as various experimental tools. Even in this case, the same effect as the above embodiment can be obtained.
