Description

[Detailed Description of the Invention] Industrial Fields of Use The present invention is mainly useful as a device for indoor displays, particularly window displays for advertising, but it can also be used in a wide range of other fields.

Structure of conventional example and its problems Conventionally, commonly seen metal bar-shaped magnets are often used. but,
In this configuration, the shape is fixed and cannot be freely changed to a desired shape.

There are also magnets that are simply magnetized by mixing ferrite powder into soft synthetic resin. With this configuration, the material has elasticity, so it is possible to create relatively free shapes. However, although it is fine when force is applied, it is not possible to maintain the desired shape because its elasticity causes it to return to its original shape when the force is removed.

Purpose of the invention The purpose of the invention is to provide a string-like magnet that has a wide range of decorative effects and can be deformed and bent to create desired shapes.

Structure of the invention The structure of the present invention is such that a bendable metal core is coaxially provided at the center of a string-shaped magnet made by magnetizing hard ferrite powder mixed into a soft synthetic resin.

With this configuration, even a magnet with a certain degree of elasticity can be shaped into a desired shape by providing a metal core and maintain the same shape even when the force is removed.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

In Fig. 1, 1 is the string-like magnet of the present invention, and 2
is a soft magnet that is magnetized after mixing hard ferrite powder into soft synthetic resin and molding it.
3 is a metal core. The metal core 3 is a core made of a magnetic material, and the metal core itself acts as a yoke, thereby increasing the magnetic absorption force of the string magnet 1 as a whole. Examples of metals that satisfy the requirements of being magnetic and bendable include soft iron like wire and alloys mainly made of iron such as iron-nickel alloys. FIG. 2 is a cross-sectional view of the magnet shown in FIG. 1, and FIG. 3 is a longitudinal cross-sectional view thereof.

Note that the cross section of the product of the present invention is not limited to a circular cross section, but may also be a quadrangular cross section as shown in FIG. 4, or may have another polygonal or semicircular cross section. Also, the mode of magnetization is the fifth
A similar effect can be obtained even if the structure is made into a multipolar shape as shown in the figure.

FIG. 6 shows the string-like magnet of the present invention wound into a coil to form a cylinder and used as a display device with a price list, etc. inserted therein. Adjacent surfaces are firmly attracted by the magnetic absorption force of the magnet, and the elastic force of the soft magnet is suppressed by the metal core, so the terminal part 4 does not bounce back and can be freely shaped. be able to. In addition, it is also possible to make it into a spiral shape, and it can be freely used for display.

Since the product of this invention has the magnetic absorption force of a magnet, it can be freely attached to a magnetic wall or the like, making it possible to perform various displays that were previously impossible.

Incidentally, since the surface of the soft magnet can be plated with metal or colored, it is also possible to provide a more luxurious string-like magnet if desired.

The thickness of the string magnet can vary from relatively thin to thick. The thickness can be set freely as long as it can be bent freely.

Effects of the invention According to the invention, since the magnet itself is soft, it can be shaped freely, and the elasticity of the magnet can be suppressed by the metal core, so it can be used as a display device according to one's preference. or,
Because it has magnetic absorption, it can be freely shaped into three-dimensional shapes on walls, etc., and depending on the cross-sectional shape, various shapes such as coils and waves can be created.
