In a block toy using a conventional magnet, when the block (a) and the block (b) are connected, the magnet rotates because the magnet rotates and the north and south poles approach each other. Even if not, they may be joined (adsorbed), and there is a problem that the block (a) and the block (b) can be connected by being shifted by about half the length of the entire magnet (see FIGS. 5 and 6).
In addition, when they are connected in such a way, when the connection position is adjusted after connecting the block (a) and the block (b), another block (c) that has already been connected and the block (a). Alternatively, the position with respect to the block (b) may be shifted. As described above, the block toy using the conventional magnet has a problem that it requires an advanced technique to connect the blocks to each other and is not suitable as a toy for infants.
An object of the present invention is to provide a block toy that can be easily connected and does not require position adjustment.

  A feature of the block toy of the present invention is a block toy having a magnet as a connecting means, wherein the magnet is a disc-type or ring-type magnet in which one or more of the poles are magnetized with one or more poles or two-sided multipole magnets. The gist is that the magnet is held so as to freely rotate about a perpendicular line passing through the center of the circle corresponding to the magnet of the mold or ring type and perpendicular to the magnetized surface.

  A disk-type or ring-type magnet in which a magnet has four or more poles with single-sided multipole magnetization or double-sided multipole magnetization is single-sided multipole magnetization (axial magnetization) or double-sided multipole magnetization with four or more poles. Means a magnet having a disk shape or a ring shape (see FIGS. 3 and 4). For example, a magnet that is magnetized on one side or on both sides of four poles is configured as a disk type or ring type in which four sector poles are alternately arranged. A magnet magnetized on one side or on both sides of six poles is configured as a disk type or ring type with six sector poles arranged alternately. Further, a magnet magnetized on one side or both sides on eight poles is configured in a disk type or ring type with eight fan-shaped poles arranged alternately.

  The multipolar magnetization method may be either single-sided magnetization or double-sided magnetization, but single-sided magnetization is preferable from the viewpoint of magnetic force and the like.

The center hole of the ring-type magnet is preferably as small as possible from the viewpoint of the connection strength (magnetic force) of the block toy.
The size and material of the magnet are preferably light, small, and thin, but are appropriately determined based on the size and weight of the block toy.

  The number of magnetic poles is not limited as long as it is 4 poles or more, but 6 poles or more are preferable from the viewpoint of the necessity of position adjustment (easiness of displacement of the connecting position), and 10 poles or less from the viewpoint of connecting strength (magnetic force). Is preferred. That is, the number of magnetic poles is preferably 6, 8, or 10. It is impossible for the number of magnetic poles to be odd because of the magnet configuration.

  The magnet is held so as to freely rotate about a perpendicular line passing through the center of a circle corresponding to the disk-type or ring-type magnet and perpendicular to the magnetized surface. The center of the circle corresponding to the disk-type or ring-type magnet means the center point with respect to the outer circumference of the disk-type or ring-type magnet. By holding the magnet so that it rotates freely, even if the pole of the magnet and the pole of the other magnet facing it are the same or misaligned at the connecting position of the toy blocks to be connected, The poles of the magnets that freely rotate and are opposite to each other can be easily reversed (combination of N and S poles) and can be connected at a predetermined connection position.

The disk-type or ring-type magnets are connected to each other by overlapping the disk-type or ring-type magnet of the other magnet to be connected and the corresponding circumferential portion. That is, when the circumferential parts of the magnets overlap each other, the block toy is connected at a predetermined connection position.
Therefore, in one set of block toys, the magnets are preferably the same size. If the magnets are different in size, the blocks may be misaligned and connected (if the purpose is to misalign and connect, the magnets may be combined in different sizes).

In connecting block toys, the magnets may be directly joined (adsorbed) to connect the blocks (the magnetized surface becomes the connecting surface), or the members constituting the block toy (connecting surface) The magnet and the magnet may be joined (adsorbed) via the.
When joining (adsorbing) via a member constituting a block toy, it is preferable that this member does not stick to the magnet as long as the strength can be secured, and is as light and thin as possible, for example, made of plastic, ceramic, wooden or paper These members are preferable.

A magnetized surface is a flat surface that has four or more poles, a single-sided multipole magnetized (axially magnetized) surface, or one of two-sided multipole magnetized surfaces, and a connecting surface that connects block toys together. Is parallel to the plane.
In addition, when the magnets are directly connected (when there is no other component member of the block toy between the magnets to be connected), the magnetized surface (in the case of double-sided multipolar magnetization, One surface; hereinafter the same, and omitted) and the connecting surface coincide.
The center of the circle corresponding to the disc-type or ring-type magnet is the center point with respect to the outer circumference of the disc-type or ring-type magnet, and is the point where all the sector poles are in contact or at the same distance ( The magnetic force at this center is 0).
