Description

Magnetic toys combined with single-sided multipole magnets {The magnetic toys}

The present invention relates to a magnetic toy combined with a one-sided multipole magnet, and more particularly, one or more independent grooves are formed on at least one surface of a unit block element in the shape of various polyhedrons. After the multi-pole magnets are built to rotate horizontally on a plane, the caps are coupled to the open ends of the grooves so that the magnets inside the grooves do not separate to the outside. When the magnetic pole arrays between the one-sided multipole magnets are the same, the magnets act on each other while the magnets rotate horizontally on the plane as the top by the repulsive force, so that the unit block and the block have the polarity of the magnets coupled to each other. Regardless of, the present invention relates to a magnetic toy in which a one-sided multipole magnet is attached, which can always be attached to each other.

Among various children's toys, Lego, a kind of block toys, is widely sold in many countries around the world as a representative toy that helps children's creativity and plays for a long time instead of a short time. .

The LEGO is a toy that is very helpful for improving children's imagination and creativity because it can be assembled according to the tastes and ideas of each child by using small unit blocks of various shapes. It is a typical toy that even adults can enjoy together, from infants to elementary school students, such as by allowing the blocks of different sizes to be assembled together by making the size ratio between the different unit blocks constant.

However, the LEGO is subject to the constraint that a specific shape of the unit block is required to make a specific shape in accordance with its characteristics, each unit block is a three-dimensional shape based on a cuboid or a cube, various kinds of themes Having a lego makes it difficult to store the bulky parts, and there is a problem that it takes too much time to assemble a particular shape because it takes a lot of time to find a particular part among the many lego parts collected.

In order to solve the above-mentioned drawbacks of Lego, there is no formal basic sculpture shape related to a specific theme. Therefore, magnetic play toys that are beneficial for cultivating geometric creativity without being influenced by preconceived notions when creating sculptures have been developed. Same as

In general, the conventional magnetic play toy is wrapped with a synthetic resin outer shell, and composed of a magnetic stick and a metal sphere coupled to both ends of the metal rod permanent magnets, the plurality of magnetic sticks continuously through the metal sphere It is a toy that allows you to make a model or structure you want by connecting it.

In other words, strictly speaking, it is possible to create a three-dimensional model of various sculptures by using a magnetic stick that acts as a two-dimensional line and a metal sphere that acts as a one-dimensional point, although it has a three-dimensional volume. It is the magnet play toy that can improve the understanding and creativity of the perceptual ability and the geometrical sculpture.

As described above, the conventional magnetic play toy composed of spheres and sticks can make various geometrical models, and can also create three-dimensional shapes, that is, polyhedrons, but there is a lack of planes for children's education. .

In particular, before entering elementary school, many children need to be educated about various polyhedrons. Therefore, many polyhedrons can be used to teach the shape and characteristics of various polyhedrons such as tetrahedrons, hexahedrons, and polygonal columns. There are educational toys composed of blocks, but conventional polyhedral blocks are made of wood or synthetic resins, etc., and are easily collapsed by a small external force when laminated.

In order to solve the problems of the conventional polyhedral block as described above, a polyhedral block having a magnet coupled thereto has been developed. An adsorbent is disclosed in Japanese Patent Laid-Open No. Hei 6-302425.

The adsorbent includes an accommodating body having an open-sided cube having an inner space, and a spherical magnet body capable of rotating in a state of being enclosed in a lid and an inner space of the accommodating body. Since it is rotatable, a large number of hexahedral adsorbents can be freely contacted regardless of the polarity of the magnet body, and the plural adsorbents are inserted and fixed at regular intervals so as not to protrude on each side of the unit polyhedral block. Polyhedral blocks can also be stably contacted with each other by magnetic force.

In addition, Korean Patent Publication No. 457305 discloses a rotating magnet coupling device and a prefabricated toy having the same, which are inserted into the grooves formed on each side of the unit polyhedral block, and then the magnet does not exit the groove. By coupling the cap to each groove so that the magnet is rotatable by flow inside the groove, the magnet has almost the same effect as the invention of the Japanese Utility Model Registration Publication.

That is, the inventions disclosed in the Japanese Patent Laid-Open Publications and the Korean Patent Laid-Open Publications, respectively, have the feature that two unit blocks can always be attached to each other irrespective of the polarity of the magnets of two unit blocks which are adjacent by rotating the magnet.

However, the magnets used in most of the conventional magnetic toys including the invention and the invention are single-sided monopole magnets. For example, in the case of a cylindrical magnet, the N pole is flat on the top surface, and the S pole is flat on the bottom surface and is flat. With this formed structure, when one magnet is rotated under repulsion by another magnet, the central axis itself must be rotated by 180 ° without the top axis being rotated on a plane with the central axis of the magnetic pole array direction as the rotation center.

Therefore, the width or depth of the space in which the magnet is embedded must be larger than the maximum diameter (or length) of the magnet, and thus, the size of the groove that provides the space in which the magnet is embedded is unnecessarily large, so that the radius of rotation is Although a certain spherical magnet is used, the spherical magnet is not only difficult to manufacture than a cylindrical magnet or a disc magnet, but also has a problem that the adhesive force is poor because it does not have a flat surface.

The present invention has been devised to solve all the problems of the conventional block-shaped magnet toy coupled to the magnet as described above, the two sides of the central axis is changed, that is, does not rotate in a manner that the up and down direction of the magnet is changed. With the center axis of rotation in place, the magnet is rotated on a plane such as a spinning top to minimize the depth of the groove, making it easy to form grooves, and also to make small unit block elements. It is an object of the present invention to provide a magnetic toy.

The above object of the present invention is achieved by a one-sided multipole magnet having a plurality of magnetic poles on one flat surface.

The magnet toy in which the single-sided multi-pole magnet of the present invention is combined is one on at least one side of a unit block element having various polyhedron shapes such as a cube shape, a panel shape close to a plate, and a bar shape having a relatively long length compared to a cross-sectional dimension. When the upper surface is formed, one single-sided multipole magnet is inserted into each of the upwardly open grooves, and a cap is coupled to the upper end of the groove, that is, the open end, so that the magnet inserted therein is separated outward. As a structure not to be, there is a technical feature of the present invention to insert a single-sided multi-pole magnet in each groove instead of a general single-pole magnet.

The one-sided multipole magnet is a magnet having a plurality of magnetic poles formed on one flat surface. In the case of a cylindrical magnet having two magnetic poles formed in a longitudinal direction, two magnetic poles are formed on the same plane with respect to a side surface parallel to the magnetization direction. Although it may be referred to as a pole magnet, it is a unipolar magnet based on a flat surface, that is, a top surface and a bottom surface, and is called a unipolar magnet because the main magnetic pole used for attraction or repulsion is N or S unipolar pole.

Of course, in the case of a bar magnet having a rectangular cross section, it becomes a single pole when referring to both ends of the longitudinal direction, and a multipole when referring to the longitudinal side, and the division thereof is a single pole magnet or a two pole depending on the purpose of use. It can be called a magnet.

In addition, prior to the description, the "unit block element" refers to a "body" having a polyhedron shape in which a magnet and a cap are not coupled, and the "unit block" refers to a "unit block element" in which the "magnet" and "cap" are combined. It is defined as referring to.

The one-sided multipole magnet constituting the magnet toy of the present invention is a magnet in which a plurality of magnetic poles are alternately formed on one flat surface (hereinafter referred to as "multipolar surface") instead of one magnetic pole. In the case of a multipole magnet in which a plurality of magnetic poles are alternately formed, when a repulsive force is generated between two mutually opposing multipolar surfaces by adjacent identical magnets, a conventional magnet that rotates in a manner of inverting top and bottom, and attracts force to each other In contrast, the multipole magnet is horizontally rotated in the same manner as a top on a plane with its center as the center of rotation in the placed state.

That is, in a state where one multipole magnet is placed on the floor, the multipole surface of the other multipole magnet, which is fixed so as not to rotate, is adjacent to the multipole surface of the multipole magnet placed on the bottom, and at this time, the magnetic poles formed on the opposing multipole surfaces of the two magnets. If the arrangement of the same pole is paired, the repulsive force between the same magnetic pole is applied between each magnetic pole formed on each of the multi-pole surface of the two magnets, the multi-pole magnet placed on the floor by this repulsive force can not be backed off by the floor Bar, even if only a minute movement is given to any one of the multi-pole magnet, the repulsive force between the two magnets is resolved to rotate the multi-pole magnet on the floor by the angle that the attraction force can be applied.

As described above, the number of magnetic poles formed on the multipole surface of the one-sided multipole magnet capable of rotating as a top by a specific angle on the plane by a repulsive force is an even number of two or more, and the N pole and the S pole are arranged alternately As a conventional magnet, when magnetized in the up-down direction, the magnet is formed so that the S-pole is formed on the entire bottom surface when the entire upper surface is the N pole. However, the multi-pole magnet constituting the present invention is, for example, a large number on the upper surface. The magnetic poles of the magnetic poles are formed and the magnetized to the bottom as it is, so that the multi-poles having the same arrangement as the upper surface are formed on the bottom surface. Until the same array is maintained.

As described above, the one-sided multipole magnet, which is the most important component of the inventive magnetic toy, has a minimum radius of rotation, most preferably a shape having a pair of flat surfaces parallel to the circular flat cross section, that is, a cylinder or a disc. The shape of the phase is most preferred, and considering the size of the groove into which the magnet is inserted, the closer to the disc, the more preferable.

Each magnetic pole formed on the flat circular multipole surface is magnetized by the same area, and each magnetic pole has a fan shape having the same center angle.

At this time, when the multipolar plane is circular, the vertices of each pole of each magnetic pole having a circular fan shape meet at the center of the circular multipolar plane, and thus, it is impossible to form an array of magnetic poles consisting of four or more poles. Therefore, the circular multipole surface in which the magnetic poles are alternately arranged should not be a pure circular surface but should have an annular shape with through holes formed in the center so that a plurality of magnetic poles do not collect.

However, in the case of two poles, a circular multipolar plane is also possible.

The grooves formed on each side of the unit block element for rotatably inserting the one-sided multipole magnet as described above are fixed in position so that when the two unit blocks are attached by the magnet attraction, It cannot be moved in a sliding manner to change its position.

That is, the other unit block cannot be moved with respect to one unit block while the two unit blocks are attached, and in order to do so, the unit block element is attached to the attachment surface of each unit block element along the line corresponding to the movement trajectory to move the unit block. The grooves must be arranged in succession.

However, arranging a plurality of grooves on the movement trajectory line of the unit block as described above not only increases the manufacturing cost by complicating the manufacturing process of the unit block but also excessively increases the number of magnets used.

Accordingly, in order to effectively move the other unit block with respect to one unit block in two unit blocks that are in close contact with each other by the attraction force of the magnet, the independent grooves of the point type having a planar area in which only one multipole magnet can be inserted (hereinafter, It is preferable to form a "dotted groove" into a straight groove having a long length.

That is, the one-sided multi-pole magnet is allowed to flow from one side of the surface of the unit block to the other side along the linear groove, so that the other side unit block can move freely along the longitudinal direction of the linear groove with respect to the one side unit block in a close state. do.

At this time, the multi-pole magnet is able to flow along the longitudinal direction inside the linear groove, and can also rotate on the same plane as the top.

Then, the planar area of the point-shaped groove is widened in a range not larger than the area of the surface of the unit block element (referred to as an "expansion groove") to allow the multipole magnet to move freely therein, thereby avoiding linear movement. It is also possible to freely move the unit block more than in the case of the straight groove.

In addition, the inside of each of the linear groove and the expansion groove may be partitioned into two or more compartments, and a plurality of unit blocks may be attached to one side of the unit block by inserting a multi-pole magnet into each compartment.

In addition, among the compartments of the linear groove or the expansion, there may be a compartment that becomes an empty space in which the multipole magnet is not inserted, if necessary, which is caused by the attraction of the multipole magnets inserted into the two compartments facing each other. This may interfere with the action of the multipole magnets coupled to other unit block elements.

Details of the technical configuration and the effect of the above object of the present invention will be clearly understood by the following detailed description with reference to the drawings showing a preferred embodiment of the present invention.

It consists of a cap 13 fixedly coupled to its open end such that each groove G provided in the unit block element 11 is covered.

At this time, the cap 13 is made of a non-magnetic material, when the transparent material is made of a magnet inside the groove (G) can be further intrigued by children.

In addition, the groove G may have a shape of a dot-shaped groove G1 into which one multipole magnet 12 is inserted, and as shown in FIGS. 3 to 5, respectively, a straight groove G2 or a plurality of grooves. The multi-pole magnet 12 may be formed in the form of an expansion groove G3 in which the planar area is extended so that the multi-pole magnet 12 may be inserted.

In addition, in the case of the linear groove G2 or the expansion groove G3, it is also preferable to divide the inside thereof into at least two spaces and to selectively insert one multipole magnet 12 into each compartment space g. .

In addition, the single-sided multi-pole magnet 12 inserted into the groove G, as shown in Figure 6, a pair of multi-pole surface (P) (P ') parallel to each other and have any shape of circular or annular shape. ) Is a polyhedral structure having one or more N poles and an S pole arranged alternately over 360 ° on one side of the multipolar plane P, and the magnetic pole array shape is maintained while the other poles P 'are the same. The magnetic pole array is extended, and the center angle of each magnetic pole formed on the multipolar plane P (P ') is 360 ° / n (n is the number of magnetic poles).
