Abstract

The present invention relates to a polyhedral toy assembly with magnets, capable of not only being combined with other polyhedron in all directions while minimizing the number of required magnets but also improving binding strength. The polyhedral toy assembly has magnets installed to be movable in a polyhedron having three or more flat or curved surfaces. The present invention can combine a hexahedron, which used to need six magnets, i.e., one magnet on each surface, in any direction using only four magnets and can form a stable block structure owing to the firm polarity structure of the magnets even when blocks are stacked because the magnets (M) can move from the center of one surface of the polyhedron (P) to one side of the surface.

Description

{Polyhedron erector set with magnet}

The present invention relates to a magnetically-mounted polyhedral assembling toy, and more particularly, to a toy having a magnet, which can minimize the required number of magnets made of expensive rare-earth minerals, The children who are growing up are able to play with and improve the spatial perception ability and the creativity as well as to give the cooperation and sociality.

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

Among them, the article related to the present invention is one in which a magnet is inserted into a polyhedron block or a magnet pad is attached so that they can be mutually coupled by a magnetic force. This is also called a magnet block or a magnet block. In the present invention, It is collectively referred to as an attachment polyhedron assembly toy.

In order to make the polyhedrons coupled with the magnets continuous in all directions, at least one magnet must be used for each surface. As the polyhedrons are combined, the larger the size of the combined body, There is a problem that the number of the magnets is increased or the magnet having a high Gauss is used.

On the other hand, permanent magnets are classified into Alico magnets, ferrite magnets, and rare earth magnets. Of these magnets, rare-earth magnets are superior in magnetic properties to the other two types. For example, the characteristics of the Nd-based magnets are ten times better than those of the ferrite magnets. The Nd-based magnets are composed of additive elements having Fe of about 60%, Nd of about 30%, and the remainder of Dy. The Dy content of these depends on the use of the magnet. On the other hand, Dy is much lower than Nd (25 ppm), which is higher than Au (0.004 ppm) and Pt (0.01 ppm) at 4.8 ppm. In addition, mineable mines are almost exclusively located in China, and since China has recently adhered to its export restriction policy, there is currently a problem of supply of rare earths. A more serious problem is that these supply and demand problems are expected to become more severe in the future.

According to a search made by the applicant of the present invention, it is possible to provide a rotating space in which a magnet can rotate, so that a magnet rotates according to the polarity of a magnet to generate a repulsive force with another magnet, Examples of the installation include a block with a magnet for teaching materials of Japanese Utility Model Registration No. 3069505, a toy assembly block of Japanese Patent Publication No. 2010-234050, a toy of Japanese Patent Application No. 2011-92321, a panel type magnet toy of Korean Patent No. 24154, Japanese Patent No. 546071, and polyhedral block toys with magnets of Korean Patent No. 629306 are disclosed.

On the other hand, in the above-mentioned prior art magnetically-adhered block toy, there is not proposed a method of maintaining or increasing the existing coupling force while reducing the number of magnets, but rather a structure in which the required number of magnets is increased In addition, in the above-mentioned conventional technique, the surface on which the magnetic force is applied and the surface on which the magnetic force is absent and the magnet is absent and the surface on which the magnetic force is not applied are distinguished so that the user can plan in advance and assure trial- No technology has been proposed for this.
