Abstract

(57) [Summary] [Purpose] To make it possible to fix the post on the cover sheet using a permanent magnet. [Structure] An intermediate sheet 3 made of a magnetic material and a reinforcing sheet 5 made of paper or cloth are attached to the front surface of the intermediate sheet 3 and the back surface of the intermediate sheet 3 by an adhesive, respectively.
The poster is held by the magnetic attraction force by locating the poster on the top and arranging the permanent magnet on it.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a surface sheet material attached to the surface of a bulletin board, a wall or the like, and more particularly, the present invention relates to a surface sheet material suitable for fixing a printed matter or a posted matter such as a photograph to the surface.

[0002]

[Prior art]

 In general, this kind of surface sheet material has a structure in which a paper or cloth reinforcing sheet is attached to the back side of the cover sheet, and an adhesive is applied to the reinforcing sheet on the back side to attach to the front surface or wall surface of the bulletin board. It

[0003]

[Problems to be solved by the device]

 However, in the case of such a surface sheet material, when the posted matter is fixed on the cover sheet, a thumbtack must be used, fixing is troublesome, and there is a problem that the posted matter has a hole.

The present invention has been made in view of the above-mentioned problems, and since it is possible to fix the bulletin board by using a permanent magnet, the bulletin board can be easily fixed and the bulletin board may be damaged. An object is to provide a surface sheet material that does not contain

[0005]

[Means for Solving the Problems]

 The invention according to claim 1 is one in which a surface mounting sheet is attached to the surface of an intermediate sheet made of a magnetic material, and a reinforcing sheet is attached to the back surface.

According to a second aspect of the present invention, an intermediate sheet made of a magnetic material is integrally attached to the front surface with a cover sheet and a rear surface with a reinforcing sheet via a synthetic resin film.

[0007]

[Action]

 When the poster is placed on the cover sheet and the permanent magnet is placed on the cover, the poster is held and fixed on the cover sheet by the magnetic attraction between the intermediate sheet and the permanent magnet inside.

In the surface sheet material of claim 2, since the synthetic resin film is interposed between the intermediate sheet and the reinforcing sheet, even if a water-based adhesive is used when sticking to a bulletin board or a wall surface, the Does not seep into the intermediate sheet, and there is no risk of the intermediate sheet rusting.

[0009]

【Example】

 1 and 2 show a bulletin board 2 to which a surface sheet material 1 according to a first embodiment of the present invention is attached. The surface sheet material 1 is formed by integrally bonding an outer sheet 4 on the front surface of a middle sheet 3 made of a magnetic material and a reinforcing sheet 5 on the back surface thereof with an adhesive. The surface sheet material 1 is supplied in a long shape having an appropriate width, and the surface sheet material wound in a roll is cut and used according to the size of the attached portion.

The cover sheet 4 is made of a synthetic resin foam such as vinyl chloride and has a surface coated with a synthetic resin film 7 such as vinyl chloride. This synthetic resin film 7 is used to wipe off dirt and prevent water from seeping inside. The synthetic resin foam has a function of closing the holes due to the restoring force even if the holes are formed by the use of the thumbtack, and is particularly suitable for bulletin boards. It is also possible to use

The intermediate sheet 3 is made of an iron foil whose surface is galvanized for rust prevention. This iron foil is obtained by pickling the hot-rolled coil, finishing it to an intermediate thickness by cold rolling, and then re-rolling it to make it ultrathin. Bending strength is given.

The reinforcing sheet 5 is for reinforcing the covering sheet 4, and a water-based adhesive for sticking to a display board or a wall surface is applied to the back surface of the reinforcing sheet 5. As the reinforcing sheet 5, in addition to paper materials such as flame-retardant paper and kraft paper, cloth such as knitted fabric is used.

FIG. 3 shows the structure of the surface sheet material 1 according to the second embodiment of the present invention. The surface sheet material 1 has a structure in which a reinforcing sheet 5 is attached to the back surface of the intermediate sheet 3 via a synthetic resin film 6 with an adhesive. The synthetic resin film 6 is for preventing the permeation of water into the intermediate sheet, and is made of a water impermeable film material such as a polyester film. The rest of the configuration is the same as that of the first embodiment, and the corresponding components are designated by the same reference numerals and the description thereof is omitted.

The surface sheet material 1 having the above structure is cut into a required length, and a water-based adhesive is applied to the back surface of the reinforcing sheet 5 and attached to the front surface or wall surface of the bulletin board. When fixing the posted matter on the surface sheet material 1, the posted matter is positioned on the cover sheet 4 and the permanent magnet is arranged in an appropriate position on the posted matter. The sign is held by the magnetic attraction force acting between the permanent magnet and the internal intermediate sheet 3 and fixed on the mounting sheet 4. Since the permanent magnet is used as a fixing means for the posted matter, the posted matter is not damaged.

In the second embodiment, since the synthetic resin film 6 is interposed between the intermediate sheet 3 and the reinforcing sheet 5, moisture from the back surface is blocked by the synthetic resin film 6 and the intermediate sheet 3 is reached. It does not permeate, and rust is prevented from being generated on the intermediate sheet 3.

[0016]

[Effect of device]

 As described above, in the present invention, since the intermediate sheet made of a magnetic material is provided inside, the poster can be easily fixed by using the permanent magnet, and the poster is not damaged.

In the surface sheet material according to the second aspect, since the synthetic resin film is interposed between the intermediate sheet and the reinforcing sheet, there is no fear that water will permeate into the intermediate sheet, and rusting of the intermediate sheet can be prevented. The practical effect is remarkable.
