[0004]

However, in the above-mentioned conventional shutter display device, it is essential that the shutter be made of a soft magnetic material such as iron, and the shutter made of a non-magnetic material such as aluminum is required. Since the magnet sheet constituting the display sheet cannot be magnetically attached, it was impossible to use the above-described shutter display device. Further, although the weight of the magnet sheet occupies about 3/4 of the weight of the entire display sheet although it is quite thin, the display sheet becomes considerably heavy as a whole, and there is also a winding device for feeding and winding the display sheet. It had to be large-scale to some extent, and in order to exchange the display contents, it was necessary to replace only the design sheet on the surface of the display sheet at the site, which was troublesome.

Accordingly, the present invention relates to a display device which can be used for advertisement and decoration useful for the wall surface of a shutter, and which can be installed particularly on a shutter made of a non-magnetic material, which has been impossible so far. By removing the magnet sheet that occupies the weight of the display sheet from the display sheet, the size and weight of the entire apparatus can be reduced to improve safety, and at the same time, the display apparatus for shutters can be easily installed and maintained and the display sheet can be easily replaced. The purpose is to provide.

Reference numeral 3 denotes an adhesive or the like on the back surface of each slat 2a constituting the shutter 2. A back yoke 4 is disposed on the opposite side of the magnet 2 from the shutter 2 and made of a soft magnetic material exhibiting a yoke effect.
A take-up roll rotatably supported by a spring member or the like, which is rotatably supported at the upper part of the front of the take-up roll; Display sheet.

The magnet body 3 provided on the back surface of each slat 2a of the shutter 2 may be a rigid body formed by sintering or compressing magnetic powder, but a synthetic resin material mixed with magnetic powder may be used. It is formed in a strip or plate shape, and has N poles and S
The magnet body 3 formed by alternately multipolarizing the poles at a pitch of several millimeters is more preferable because the magnet body 3 can be freely deformed according to the curved surface or the uneven shape of the slat.

The magnet body 3 is housed and fixed in a back yoke 4 having a substantially U-shaped cross section so as to conform to the concave shape of the back surface of the slat 2a. Then, the back yoke 4 housing and fixing the magnet body 3 is fixed with an adhesive, a double-sided adhesive or the like with the magnet body 3 facing the back surface of the slat 2a. In addition to the method of fixing with an adhesive or the like, although not particularly shown, a method may be used in which an engaging portion capable of engaging with the back surface of the slat 2a is formed on the back yoke 4, and this is fitted into the back surface of the slat 2a. The magnetic body 3 engaged with the back yoke 4 applies the magnetic field to the back yoke 4.
The thin plate 7 of the display sheet 6 can be suitably magnetized by expanding the shutter 2 on the side opposite to the shutter 2.

As shown in FIG. 2, the display sheet 6 has a thickness of about 0.1 mm and is made of, for example, soft magnetic stainless steel so that the sheet has a stiffness and is magnetically attached to the magnet body 3.

A protective film 10 made of a transparent synthetic resin is adhered to the surface of the substrate. The thin plate 7, the peelable film 8, the design sheet 9 and the protective film 10 constituting the display sheet 6 are all bonded using an adhesive member such as a double-sided adhesive or an adhesive. In consideration of the replacement of the design sheet 9, at least the peelable film 8 may be made to have a weak adhesive property between the peelable film 8 formed with 10 so that the peelable film 8 is easily peeled.

As described above, since the display sheet 6 has a configuration in which the magnet sheet is removed from the display sheet in the conventional shutter display device, the display sheet 6 is thin and lightweight (about one-fourth the weight of the conventional display sheet). Accordingly, the entire shutter display device 1 including the structure of the take-up roll 5 can be made smaller and lighter than before. This facilitates installation and maintenance of the display device for the shutter, and makes it possible to replace the display sheet for each winding roll. And when exchanging the display sheet for each take-up roll without replacing the design sheet, a peelable film is not always necessary even for the display sheet, and it is even easier to attach the design sheet directly to a thin plate. It may have a structure.

Further, in the case of a conventional take-up roll which becomes considerably heavy when the display sheet is wound, measures to be taken in the event that the bearing for supporting the take-up roll should be damaged should be considered. Display sheet 6 of embodiment
By reducing the weight as described above, there is no danger of a fall accident due to damage to the bearing, and safety is improved. Further, by arranging the magnet body 3 on the indoor side of the shutter 2 that is not exposed to ultraviolet rays or wind and rain, the life of the magnet body is also prolonged.
