Description

  The present invention relates to a polyhedral block toy combined with magnets, and more specifically, each surface of a unit block having various polyhedral shapes is provided with a floating space that crosses each surface so as not to protrude outward from the surface. By dividing the interior of the space into a number of compartments and allowing the magnets to freely move inside the partitioned floating small spaces, when the surfaces of the two unit blocks are close to each other, the proximity of the two unit blocks Even if the magnets to be magnetized have the same pole, one block of magnets rotates inside the floating small space due to repulsive force with the other magnet, and an attractive force always acts between the two magnets. Regardless of the unit block, the surface of the unit block can always be contact-coupled by magnetic force, and a large number of magnets are movably accommodated on each surface of the unit block, so It is possible to freely change can make a three-dimensional model of various forms, to a polyhedral block toy magnet is coupled.

  Among many toys for children, it is a great help to improve children's creativity and is suitable for playing for a long time instead of a short time, so Lego is a typical toy that has been widely sold in countries all over the world for a long time. (Registered trademark).

  This LEGO is a toy that is very useful for improving children's imagination and creativity by assembling various shaped parts according to children's individual preferences and thoughts. The size of each part varies depending on the year. In addition, by making parts of different sizes a certain size, it is possible to assemble parts of different sizes together, and can be enjoyed from infants to elementary school to upper grade students. Is a toy.

  However, due to the characteristics of the LEGO, in order to make a specific shape, there is a restriction that there must be a specific shape component corresponding to the shape, and each component is a three-dimensional basis based on a rectangular parallelepiped or a regular hexahedron. If you have many types of LEGO by shape and themes, the volume of the parts will increase and it will be difficult to store, and it will take a long time to search for specific parts among the many LEGO parts you have collected. Therefore, there is a problem that an excessive amount of time is required for assembling into a specific shape.

  Since there is no fixed basic model shape related to a specific theme to solve the above-mentioned drawbacks of LEGO, when creating a model, it is not influenced by preconceptions, but it cultivates geometric creativity This is as follows when a toy magnet play toy was developed.

  Generally, the conventional toy magnet play toy is composed of a magnet stick and a metal ball surrounded by a synthetic resin jacket, and permanent magnets are coupled to both end surfaces of a metal rod, and the plurality of magnet sticks are interposed with metal balls. The toys are designed to make a desired model or structure by continuously connecting them.

  Strictly speaking, it has a three-dimensional volume, but makes a model of various three-dimensional objects with a magnetic stick that acts as a two-dimensional line and a metal sphere that acts as a one-dimensional point. The magnet play toy is designed to improve the child's ability to perceive space and the degree of understanding and creativity of the geometrically shaped object.

  A typical embodiment of such a conventional magnet play toy will be briefly described as follows based on FIG. 1 and FIG.

  FIG. 1 is a perspective view showing a conventional magnet play toy in use, and FIG. 2 is a cross-sectional view showing a basic assembly structure and a cross-sectional view of a magnetic stick constituting the conventional magnet play toy.

  As shown in these drawings, the conventional magnet play toy has a metal rod 12 having disk-shaped permanent magnets 11 in close contact with both end surfaces, and an outer peripheral surface and an outer end surface S of the permanent magnet 11 covered with a synthetic resin outer skin 13. The magnetic stick 1 has a structure in which a large number of magnetic sticks 1 are connected with the metal ball 2 interposed therebetween. Each of the permanent magnets 11 having a shape is fixed, and the magnetic stick 1 is converted into a bar magnet having a circular cross section, so that one side of the magnetic stick 1 has the polarity of the N pole and the other side has the polarity of the S pole.

  And each front end surface of the magnetic stick 1 is attached to the surface of the metal ball 2 by magnetic force. Triangular structure is the most basic structure of the connection structure, and structure models of larger and various shapes can be made based on this structure.

  Here, as the disk-shaped permanent magnet 11, a rare earth series neodymium (Nd) magnet having excellent mechanical strength and corrosion resistance while reducing the size and weight of the product due to high performance magnetic characteristics is mainly used. This permanent magnet is attached to both ends of the metal rod 12 to induce dense magnetic field lines, thereby giving an effect of increasing the magnetic force of about 1000 G. The increased magnetic force causes a large number of magnet sticks 1 and metal balls 2 to be applied. It is possible to maintain a solid structure even in the case of a large structure connected to each other.

  Thus, the conventional conventional magnet play toy composed of a sphere and a stick can make various geometric models, and can make a three-dimensional shape, that is, a polyhedral shape, but has no surface. Therefore, there is a shortage for children's education.

  In particular, since children who have not yet entered elementary school need to learn about various polyhedrons, they should be able to educate the shape and characteristics of various polyhedrons such as tetrahedrons, hexahedrons, and polygonal columns, and function as play toys. There are also educational toys made up of many blocks with various polyhedron shapes, but since conventional polyhedron blocks are simply made of wood or synthetic resin, they can be easily collapsed even with a small external force during lamination. There are disadvantages to become.

  In order to solve the problems of the conventional polyhedron block as described above, a polyhedron block combined with a magnet has been developed. An example is an adsorbent (see, for example, Patent Document 1).

  The adsorbent body includes an upwardly open hexahedral storage body having an internal space, a lid, and a single spherical magnet body rotatably stored in the internal space of the storage body. This is because the magnet body is rotatable inside the storage body, so that a large number of hexahedron-shaped adsorbers can be freely contact-coupled regardless of the polarity of the magnet body, By inserting and fixing at regular intervals so as not to protrude from the surface, the polyhedral block can also be stably contact-coupled by magnetic force.

  However, the magnet body can be rotated inside the storage body, but its position is fixed, and furthermore, since one magnet is coupled to each adsorption body, the surface of one adsorption body and the other Since the surface of the adsorbent can only be contacted by 1: 1 and two surfaces of the two adsorbents cannot be attached to one surface of the adsorbent at the same time, the contact bonding state is always constant, If they are bonded in a fixed state, contact bonding is made only where the polyhedron block has a fixed adsorbent, and the contact area cannot be freely changed while maintaining the contact-bonded state.

  And the rotary magnet coupling device and the assembly-type toy provided with this are disclosed (for example, refer patent document 2). This is because a magnet is inserted into a large number of recesses formed on the surface of the polyhedron and then a cap is coupled to each recess so that the magnet is not ejected from the recesses. It is a structure that can be rotated. This has the same effects and disadvantages as those of Patent Document 1.

That is, although the invention disclosed in Patent Document 1 and Patent Document 2 can rotate the magnet and slightly move, the concave portion where the magnet is located is fixed at a certain position. It can be combined only with each other, and the size of the contact surface cannot be changed freely while maintaining the contact state in a state where the surfaces are contact-bonded. Rather, only some substantially constant forms of coupling are possible.
JP-A-6-302425 Korean Patent Registration No. 457305 Specification

  Accordingly, the present invention has been made to solve the various problems of the conventional block-type magnet play toy to which the magnets are coupled as described above, and allows a large number of magnets to float on each surface of the polyhedron. A block toy that can be combined in various forms by allowing the size of the contact surface to be freely adjusted even when the surfaces of the polyhedral block are in contact with each other by combining them. There is an object of the present invention to provide.

  In order to solve the above problems, the present invention provides an idle space formed so as to cross each surface of a polyhedron.

  The polyhedral block toy to which the magnet of the present invention is coupled is composed of a large number of unit blocks forming a polyhedron and a large number of magnets movably coupled to each surface of the unit block, so that the magnets are movably coupled. In addition, the technical feature of the present invention is that each surface of the unit block has a floating space in a direction crossing each surface.

  That is, the free space is formed in a straight line extending to one end of each surface of the unit block and the opposite end thereof, and each free space is divided into two or more free small spaces by a partition or the like. Since one magnet is accommodated in the space, the magnet can move while freely rolling in the direction crossing the surface inside the space, that is, in the longitudinal direction of the floating small space.

  In the following description, the direction with respect to the floating space will be described based on the direction formed on the upper surface of the polyhedron in order to avoid confusion of terms.

  As a typical method of forming the floating space, in the case of a wood block, it can be formed by forming a groove having a square cross section across the surface from one end to the other end of each surface, and a magnet is inserted. Later, both ends and upper ends in the longitudinal direction, which are open ends of the floating space, are sealed so that the magnet is not discharged to the outside. In the case of a synthetic resin block, a groove is formed. In addition to the above, the floating space can be formed on each surface of the polyhedron by various methods such as injection molding.

  When the partition walls that partition the floating space are thin, the magnets housed in the two adjacent small floating spaces are attached to each other by the magnetic force between the partition walls so that they cannot move. .

  Therefore, for example, when each of the free spaces is divided into three, a pair of partition walls are provided to partition one free space into three free small spaces arranged in a row, and then the central free space is excluded. By inserting magnets only in the floating small spaces on both sides, the magnets on both sides are not restrained by magnetic force, or each small floating space is formed on both sides except for the central part of the straight line across the surface. Thus, the magnets housed in the respective floating small spaces formed separately on both sides can be freely moved without interfering with each other by being separated by the sufficiently thick partition walls.

  As described above, the magnets accommodated in the direction of crossing the surface, that is, in the linearly-formed floating small space, can move linearly and can be rolled by repulsive force or attractive force. The two polyhedrons that are contact-coupled to each other can move the magnets of the two polyhedrons that are attracted to each other within the respective floating small spaces in the longitudinal direction of the floating small spaces. Even in the contact-coupled state, it can move in the longitudinal direction of the floating small space.

  That is, the contact area between the two polyhedrons can be freely changed.

  At this time, the two polyhedrons can be contact-coupled so that the longitudinal directions of the floating small spaces provided on the contact surfaces coincide with each other, or can be contact-coupled so as to be orthogonal to each other. When the directions of the floating small spaces coincide with each other, both sided polyhedron magnets can move in the longitudinal direction, and when they intersect at right angles, only one sided polyhedral magnet can move in the longitudinal direction.

  As described above, the block toy of the present invention in which idle spaces are formed on each surface forming a polyhedron can be applied regardless of the number of faces of the polyhedron, but at least parallel to each other like a hexahedron, a polygonal column, etc. It is desirable to select a polyhedron having a pair of surfaces, and to form an idle space in a direction perpendicular to both parallel surfaces on each surface where both ends are coupled to both surfaces parallel to the selected polyhedron.

  That is, for example, idle spaces can be formed on all surfaces in the case of a hexahedron, and on three surfaces excluding parallel surfaces in the case of a triangular prism in a direction perpendicular to the parallel surfaces.

  At this time, in the case of the triangular prism, it is possible to form idle spaces on both parallel surfaces, but both ends can interfere with each of the three idle spaces that are positioned on both parallel surfaces. Unlike the floating spaces formed across the three non-parallel surfaces, it is desirable that the floating spaces formed on both parallel surfaces be positioned within the surface without crossing the surfaces.

  As described above, the polyhedron block toy combined with the magnet of the present invention can change the contact area between the polyhedron and polyhedron freely when assembling a three-dimensional object using a large number of polyhedrons. Can be combined into various shapes, which can help improve the creativity of the child.

  Exemplary embodiments of the present invention will be described below in detail with reference to the accompanying drawings. In the present specification and drawings, components having substantially the same functional configuration are denoted by the same reference numerals, and redundant description is omitted.

  3 is a perspective view showing a polyhedral block toy combined with a magnet according to an embodiment of the present invention, FIG. 4 is a cross-sectional view showing an operating state of a polyhedral block toy combined with a magnet according to an embodiment of the present invention, and FIG. 1 is a partially exploded perspective view of a polyhedral block toy to which magnets according to an embodiment of the present invention are coupled. FIG.

As shown in these drawings, in the polyhedral block toy according to an embodiment of the present invention, a straight groove-shaped idle space R is formed across each surface, and the idle space R is formed by a plurality of partition walls W facing each other. A single unit block 31 that is partitioned into a large number of small floating spaces _RS and forms a polyhedron, and a large number of magnets 32 that are movably accommodated in each small floating space _RS provided on each surface of the unit block 31. , A piece-shaped upper blocking piece 33A coupled to the open upper end portion of the idle space R and isolating the idle space R from the outside, and an open space R connected to the both open ends of the idle space R. And a cap 33 formed of a side blocking piece 33B that is isolated from the cap 33.

At this time, the number of sections of the floating space R can be adjusted as necessary. However, the floating space R is partitioned into three small floating spaces _RS arranged in a row by two partition walls W, except for the central small floating space _RS. It is desirable to put the magnet 32 only in the floating small space _RS on both sides.

However, when the floating spaces R formed on the contact surfaces of the two polyhedrons are perpendicular to each other in a state where the magnets are accommodated only in the floating small spaces _RS on both sides as described above, Since there is no magnet in the small floating space _RS in the center of R, the contact coupling between the two polyhedrons becomes impossible.

Therefore, in order to prevent such a case, the magnet can be accommodated in the central floating small space _RS , but in such a case, the second small space _RS accommodated in the adjacent small floating space _RS can be accommodated. It is necessary to appropriately adjust the thickness of the partition wall W that partitions the floating space R so that the attractive force between the magnets of the two polyhedrons that are contact-bonded is larger than the attractive force between the two magnets.

  That is, it is desirable to make the attractive force between the magnets of two polyhedrons larger than the attractive force between two adjacent magnets of one polyhedron by making the thickness of the partition wall larger than the distance between the magnets between the two polyhedrons. .

And the partition wall W which partitions each idle space W can also be integrally formed on the bottom surface of the cap 33 coupled to the idle space R so that the magnet inside the idle space R is not discharged to the outside. The upper blocking piece 33A and the side blocking piece 33B of the cap 33 can be integrally formed so as to form a downwardly open “U” shape. In order not to reduce the magnetic force, as shown in FIG. 6, by forming a straight through hole H in the central portion of the upper blocking piece 33A coupled to the floating small space _RS in which the magnet 32 is accommodated, The polyhedral magnet 32 and the magnet 32 can be directly attached via the through hole H.

  Further, a through hole (not shown) can be formed in the side surface blocking piece 33B. The idle space R can be completely blocked from the outside, or can be partially opened by a through hole.

  It is important that the cap 33 is not easily separated from the idle space R by an external force or impact. As shown in FIG. 7, the cross-sectional shape of the idle space R and the shape of the side blocking pieces 33 </ b> B and the partition wall W are set such that the lower end width w ′ is larger than the upper end width w, and the cap 33 is connected to one end of the idle space R. It is also possible to combine them by inserting them from the part to the other end side.

  The structure as described above, that is, the structure in which the idle space R is provided on each surface of the polyhedral unit block can be manufactured by various methods. In the case of a wood block, a method can be applied in which a groove-like floating space is formed across the surface from one end to the other end of one side of a polyhedron, and a cap 33 is coupled to the formed floating space. In the case of a block, as shown in FIG. 8, after manufacturing a square plate-like block plate 31 </ b> A in which an idle space R having a through hole H is formed from one end to the other end of the lower surface by a method such as injection molding. A hexahedron block can be made by combining six block plate bodies 31A.

At this time, a large number of partition walls W may be integrally formed or inserted into the floating space R so as to be partitioned into a large number of small floating spaces _RS , which are sufficiently thick to prevent magnetic force from reaching them. By inserting one partition wall at the center, it can be partitioned only into two small floating spaces _RS .

As noted above, to accommodate the one magnet without partitioning the interior of the formed floating space R of two or more idler small space R _S, freely floating from one end of the floating space R to the other end It can also be possible.

  However, as described above, when the floating space R is made into one space, since there is one magnet on the surface of one block, it becomes impossible to contact-couple two blocks together on one surface of one block. The idle space R can be not partitioned as necessary.

  In addition to the above method, as shown in FIG. 9, if the surface on which the floating space is to be formed is a “reference surface”, the reference surface from one side that matches the reference surface of the polyhedron block 31 to its opposite side The idle space R can be formed in such a manner that at least one or more holes that are parallel to each other are provided directly underneath. A straight through hole H can be formed from the inner peripheral surface of the idle space R formed in this way to the reference surface immediately above it.

Also, as shown in FIG. 10, it is possible to form floating small spaces _RS on both sides of a straight line that crosses each surface. In this case, the unprocessed portion between the two floating small spaces _RS serves as a thick partition wall W, and the cap 33 coupled to each floating small space _RS is simply formed in an “L” shape. it can.

In addition to the methods described above, there can be various methods capable of forming the idle space R. For example, after the idle space R is partitioned by a method of forming a groove crossing the surface in each surface of the polyhedron or by penetrating a through hole directly below the surface, the partition wall W partitioning the interior thereof, and the interior There may be various structures such as providing a blocking member such as a cap 33 that is coupled to the open end of the floating space R in order to prevent the housed magnet from being slipped out. Regardless of a specific method or structure, the present invention forms a floating space R on each face of a polyhedron or directly below it, and separates the free space R on both sides of a straight line that crosses each face. The magnets 32 are formed in the two free small spaces _RS to be accommodated or divided into three free small spaces _RS arranged in a row by the partition walls W, and only in the free small spaces _RS on both sides except the center. There are technical features in the basic structure of

  The unit blocks constituting the present invention are not limited to specific materials such as wood and synthetic resin, but wood is most desirable for children's education.

  The block toy of the present invention having the above-mentioned structure is not related to the shape of the polyhedron, but is parallel to the formation of the floating space R and the blocking member for blocking both ends thereof, such as a tetrahedron. A polyhedron having at least one pair of parallel surfaces such as a hexahedron or a polygonal column such as a cylinder is more preferable than a polyhedron having no two surfaces. As shown in FIG. 11, the free space R formed on each surface of such a polyhedron is formed in a direction perpendicular to two parallel surfaces, and the free space R is also formed on the parallel surfaces. In some cases, it is preferable to lie within the plane without crossing the parallel plane.

  However, the magnet 32 accommodated in the floating space R having a surface perpendicular to the parallel surface acts in a state where the blocking member is interposed, but the blocking member that blocks both ends of the floating space R from the outside. It is possible to prevent the idle space R from being formed on the parallel surfaces by reducing the thickness of the through hole H.

  And the free space R formed in each surface is shown in FIG. As shown in B, two to four can be formed in parallel with each other, and as shown in FIG. 13, they can be formed in a closed loop shape that starts around one side and goes around. In this case, the idle space formed on the parallel surfaces can be formed so as to cross the surfaces.

At this time, when defining the floating space R formed in a closed loop on a number of floating small space RS is provided with a thin partition wall thicknesses, and the number of floating small space R _S in an even, every other floating small spaces By accommodating the magnets, the adjacent magnets can be prevented from adhering to each other, or the magnets can be accommodated in all of the floating small spaces _RS while increasing the thickness of the partition walls.

And, in the case of the idle space R formed in the closed loop shape as described above, by connecting one magnet 32 to each idle space R without dividing each idle space R into the idle small spaces _RS , Although the magnet 32 can be rotated around the polyhedron along the idle space R _S , in this case, two or more polyhedrons cannot be coupled to the single polyhedron. Also in the case of R, it can be divided into a large number of small floating spaces _RS .

  FIG. As shown in C, in the case of a cylindrical block having a fan-shaped cross section with no part, the idle space R can be formed along the outer peripheral surface on the arc.

  As described above, the block toy of the present invention is composed of a large number of polyhedral unit blocks. As shown in FIG. 15, numbers, letters, patterns, etc. are printed and connected when contacting each surface of the unit block. It is possible to make a child learn numbers and various patterns interestingly by connecting the same pattern plate D having the same planar shape to each surface of the unit block in a separable manner.

  As mentioned above, although preferred embodiment of this invention was described referring an accompanying drawing, this invention is not limited to this example. It will be apparent to those skilled in the art that various changes and modifications can be made within the scope of the claims, and these are naturally within the technical scope of the present invention.
