Abstract

The present invention relates to a magnet-attached polyhedral construction toy, in which a polyhedral body toy can be coupled to another polyhedral body in every direction while minimizing the number of required magnets, and the coupling force is improved, and the polyhedral body having a surface with three or more planes or curved surfaces has movable magnets therein. Each magnet (M) moves from the center of one side of the polyhedral body (P) to the edge of the side. Therefore, differently from conventional hexahedrons which require six magnets in total, i.e., one for each side of the hexahedron, the construction toy of the present invention enables a hexahedron to be coupled with another hexahedron in any direction using only four magnets, and the polar structures of the magnets are firmly formed when blocks are stacked, thus achieving a stable block structure.

Description

Magnetic Polyhedron Assembly Toys

The present invention relates to a magnet-attached polyhedral assembly toy, and in detail, it is possible to combine with other polyhedrons in all directions while minimizing the number of magnets made of expensive rare earth minerals, as well as to improve the bonding force and maintain a stable coupling state. By allowing children to grow up to play with them, they can contribute to the development of spatial perception and creativity, as well as to give cooperation and sociality.

In general, toys for the development of children's spatial perception and creativity are called various names, such as building blocks, polyhedrons, puzzles.

Among the articles related to the present invention, a magnet is inserted into a polyhedron block or a magnetic pad is attached to each other so as to be mutually coupled by magnetic force, which is also called a magnet block or a magnet block, and in the present invention, the magnet It is collectively called an attachable polyhedron assembly toy.

On the other hand, in order to be able to combine the magnets in the polyhedron can be continuously combined in all directions, at least one magnet should be used on each side, and as the polyhedrons are combined, the larger the combined solids will not be able to withstand the force of the weight. There is a problem to increase the number of magnets or to use expensive magnets with high Gaussian by collapse.

On the other hand, permanent magnets are classified into alico magnets, ferrite magnets, rare earth magnets, etc. Among these, rare earth magnets have superior magnetic properties compared to the other two types. For example, the properties of Nd magnets are 10 times better than ferrite magnets. Nd magnets are composed of about 60% Fe, about 30% Nd, and the rest of Dy and other additive elements. Among them, the Dy content depends on the use of the magnet. On the other hand, Dy has a crust present mass ratio of 4.8 ppm, which is higher than Au (0.004 ppm) and Pt (0.01 ppm), but is very low compared to Nd (25 ppm). In addition, due to the fact that the mining mines are almost limited to China, and China has recently adhered to the export restriction policy, heavy rare earth supply and demand problems are occurring. The more serious problem is that this supply and demand problem is expected to intensify in the future.

Applicants have searched in the prior art related to the present invention, by creating a rotating space in which the magnet can rotate to rotate the magnet according to the polarity of the magnet to generate repulsion with other magnets, or to allow the magnet to flow in the flow space It is installed as a block with a teaching material magnet of Japanese Utility Model Registration No. 3069505, a toy block for construction of Japanese Patent Publication No. 2010-234050, a toy of Japanese Patent Publication No. 2011-92321, a panel-type magnetic play toy of Korean Patent No. 24154, Korea A three-dimensional magnetic play toy of Patent No. 575571, a polyhedral block toy in which a magnet of Korean Patent No. 629306 is combined, and the like are disclosed.

On the other hand, in the magnetic block toy according to the prior art described above can not reduce the number of magnets while maintaining or increasing the existing bonding force is not proposed, but rather the structure required to increase the number of magnets In addition, in the above-mentioned prior art, a magnet is included so that the surface of the magnetic force can be distinguished from the surface of the magnetic force not acting so that the user can plan in advance and reduce trial and error before assembling.

If so, it should be interpreted in the same sense.

1 to 4 illustrate a magnet arrangement structure and a coupling state of a hexahedron of a magnet-attached polyhedral assembly toy according to an embodiment of the present invention. The polyhedral assembly toy of the present embodiment is made of a hexahedron having a rectangular pillar shape. The hexahedron polyhedron (P) is capable of exerting magnetic force on all six surfaces (front, rear, left, right, top, bottom) by placing four bar magnets (M1, M2, M3, M4). The hexahedral magnet arrangement structure is provided in two opposing surfaces, for example, from the center of the upper surface F1 and the lower surface F2 to the sides E1 and E2 contacting the right surface F3 and the front surface as shown in the drawing. Four flow spaces S1, S2, S3, through which the magnets M1, M2, M3, M4 can flow from the center of F4 and the rear surface F5 to the sides E3 and E4 in contact with the left surface F6.

Meanwhile, in the present invention, the surface texture of the flow spaces S1, S2, S3, and S4, that is, the surface of the polyhedron and the outer surface of the flow spaces S1 to S4 have different textures, for example, smoothing the surface of the polyhedron. The surface of the flow spaces (S1 to S4) is formed to have a slightly rough feeling, or vice versa, so that the user can recognize the position of the flow space, that is, the position of the magnet, by hand sense only without looking at the eyes. Blocks can be quickly combined without making mistakes, or the visually impaired can also play with building toys and develop spatial perception and creativity.

In addition, in the present invention, the cube is not limited to the shape of the cube shown in the drawings, the cube form such as combining the two cubes shown in the drawings, a cube of another form that is divided into the vertically half of the cube shown in the figure vertically In addition, it is possible to manufacture, of course, the two corresponding surfaces are not rectangular or square, but the trapezoidal hexahedral shape, such as the shape of the magnet can be applied to various hexahedron.

In addition, in the present embodiment, as shown in the block coupling state of FIG. 4, when the polyhedrons are surface-bonded, the magnets in the corresponding flow space are coupled as closely as possible to each other, whereby another block is placed up, down, left. When coupled to the right side, the magnetic force is doubled, so that the combined state of the block is made more robust, and thus, a more stable block can be assembled.
