DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a magnetic shield blind for shielding an internal space from magnetism in a building such as an office building.

[0002]

2. Description of the Related Art In recent years, as personal computers have become more compact than conventional computers and have appeared as book computers, the introduction of computers and other OA equipment in offices has been remarkable. In such offices, important information including confidential information is increasing in information handled by OA equipment and the like. Therefore, if the OA equipment malfunctions due to the influence of magnetic noise or the like, the information therein is destroyed, or the information leaks to the outside, the reliability of the system decreases. And have a significant impact on operations. Magnetism is particularly likely to occur near transmission lines, railway overhead lines, and substations, which has a large effect. Conventionally, to prevent magnetic interference on the building side, floors,
Walls, ceilings, and rooftops are magnetically shielded using magnetic shield materials such as silicon steel plates.

[0003]

However, since there is no transparent magnetic shield member at the window of the building,
When a magnetic shield is applied to the window, the window is visually blocked, and there is a problem in that the interior becomes a closed room due to a dark feeling of strong pressure.

An object of the present invention is to solve the above-mentioned problem, and an object of the present invention is to provide a magnetic shield blind that enables daylighting and external visibility while maintaining the magnetic shield performance.

[0005]

For this purpose, a magnetic shield blind of the present invention comprises a sash frame installed in a window,
A plurality of louvers made of a magnetic shielding material that can be opened and closed so as to face the window portion, a slit-shaped lighting portion formed in each louver, and attached around the sash frame , a wall, a ceiling portion Magnetically connected to magnetic shield material
By a plurality of magnets, closing the louver when Le
At the same time as the bar overlaps,
The louvers are in close contact with each other .

[0006]

According to the present invention, when the louvers are closed, the louvers are overlapped with each other, and at the same time, the louvers are brought into close contact with each other by the magnet mounted around the sash frame, and the louvers are attached to the wall and the ceiling. Because it is magnetically connected to the magnetic shield material, the magnetic resistance does not increase and the magnetic shield performance can be maintained.
Since the louver is formed with a lighting part, it is possible to take some light even when the louver is closed. Therefore, it is possible to provide a magnetic shield blind that enables lighting and visual recognition of the outside while maintaining the magnetic shield performance.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. 1 to 3 show a magnetic shield blind according to an embodiment of the present invention. FIG. 1 is a perspective view showing a state where the blind is open, FIG. 2 is a front view showing a state where the blind is closed, and FIG. It is an enlarged front view showing the state where the circuit was constituted.

[0008] A sash frame 2 having a glass window is installed in the window portion 1. A blind box 3 is disposed above the sash frame 2, and a plurality of rectangular louvers 5 are suspended in the blind box 3 so as to face the window 1. The louvers 5 can be opened and closed with respect to the window 1 by an operation code (not shown), similarly to a known blind opening and closing structure.

As the material of the louver 5, a magnetic shielding material such as silicon steel plate, permalloy, amorphous alloy, sendust, or a combination thereof is adopted. Each louver 5 is formed with a slit-shaped or hole-shaped lighting part 6. A magnet 7 is mounted around the sash frame 2, and the magnet 7 is magnetically connected to a magnetic shield material on a wall or a ceiling. Reference numeral 8 denotes a protection plate provided below the louver 5, and reference numeral 9 denotes a connection cord.

Normally, as shown in FIG. 1, each louver 5 is opened, and when the louver 5 is closed, the louvers 5 overlap each other as shown in FIG. 2, and at the same time, as shown in FIG. The louvers 5 are closely adhered to each other by the magnet 7 attached to the periphery of the frame 2 and the louvers 5 are magnetically connected to the magnetic shield material on the wall and the ceiling, so that the magnetic resistance is not increased and the magnetic shield performance is maintained. can do. Since the louver 5 is formed with the daylighting part 6, it is possible to take some light even when the louver 5 is closed. If the louver 5 is, for example, about 100 mm wide, and if the slit width of the lighting unit 6 is about 8 mm, the magnetic shield performance will not be reduced.

Although the embodiments of the present invention have been described above, the present invention is not limited to the above embodiments, and various modifications are possible. For example, in the above embodiment,
Although the louvers 5 are arranged in the vertical direction, they may be arranged in the horizontal direction with respect to the window 1.
