Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a display sheet stretched on a display surface of an advertisement / display device, and particularly to a structure of a joint portion thereof.

[0002]

[Prior art and problems]

 A display sheet constituting the display surface is stretched on the display surface of an advertisement display device used for advertisement of products or companies. As the above-mentioned display sheet, a sheet in which a fluorine film layer is formed on the surface to prevent stains may be used, and an illumination lamp (hereinafter, referred to as a backlight) in the display device is used to display at night. A light-transmissive display sheet may be used to enable the above.

Further, in the above-mentioned display sheet, a belt-shaped basic sheet having a constant width drawn out from the original roll is spliced in the width direction so as to be adaptable to various sizes. Conventionally, as shown in FIG. The above basic sheets were joined together. The basic sheet (1) is composed of a vinyl chloride material (17) and a transparent fluorine film (11) covering the surface thereof, and the basic sheet (1) (1) is joined in the width direction. When mating, first, the side portions (12) (12) of the basic sheets (1) (1) are butted against each other. Next, by applying a translucent backing tape (2) to the back surface of the abutting portion and welding the backing tape (2) and the polymerized portion of the basic sheet (1) (1) to the adjacent basic The sheets (1) (1) are in a spliced state. After that, when the required number of basic sheets (1) and (1) are joined together, the display sheet (A) of the desired size is completed. Then, an advertisement display device is completed by attaching a display such as an advertisement to the surface of the display sheet (A) and stretching it on a predetermined frame.

However, in the above-mentioned conventional display sheet (A), dirt such as dust easily enters the joint boundary portion of the basic sheet (1) (1). Therefore, there is a problem that the joint portion of the basic sheet (1) (1) becomes unsightly. In other words, in the above-mentioned conventional one, although the basic sheet (1) (1) and the back tape (2) at its boundary are welded, the abutting portion of the basic sheet (1) (1) is exposed. ing. Therefore, the dust adhering to the surface of the display sheet (A) will enter the slight gap of the abutting portion (13) of the basic sheet (1) (1) together with rainwater or the like. Then, in the above-mentioned conventional type, the dirt accumulated on the abutting part (13) of the above-mentioned basic sheet (1) (1) becomes conspicuous and unsightly, and especially, it is backlit from the back side of the display sheet (A). At night when it is illuminated with, the abutting portion (13) of the base sheet (1) (1) becomes black in a straight line, which impairs aesthetics.

The present invention has been made in view of the above points, and is described as "a basic sheet (11) composed of a base material (17) having heat-melting property and a transparent fluorine film (11) covering the surface thereof. 1) In the display sheet for advertisements / displays formed by joining the side edges of (1), the basic sheet (1) By preventing the entry and adhesion of dirt to the joint of (1), It is an object of the invention to prevent the aesthetics of the display sheet (A) from being impaired for a long period of time.

[0006]

[Technical means]

 The technical means of the present invention for solving the above-mentioned problem is to "polymerize another basic sheet (1) on the peeling trace part of the fluorine film (11) formed with a constant width on the side part of the basic sheet (1). And the transparent adhesive tape (3) made of fluororesin was coated and adhered to the surface of the polymerized and welded portion. ”

[0007]

[Action]

 The above technical means act as follows. Since the other base sheet (1) is polymerized on the peeling trace portion of the fluorine film (11) peeled along the side of the base sheet (1) and the polymerized portion is heat-welded, Similar to the above, various display sheets (A) of different sizes can be manufactured by joining the basic sheets (1) (1) together. In addition, even if there is a minute gap that allows the entry of dirt at the joint boundary between the above-mentioned basic sheets (1) and (1), the joint boundary between the above-mentioned basic sheets (1) and (1) Since the adhesive tape (3) made of fluororesin is adhered to the surface of the portion, dirt can be prevented from entering the gap.

[0008]

【effect】

 The present invention has the following unique effects. Since it is possible to prevent dirt from entering and adhering to the joint portion of the basic sheet (1) (1), the aesthetic appearance of the display sheet (A) is not impaired for a long period of time.

[0009]

【Example】

 Next, an embodiment of the present invention described above will be described with reference to the drawings. As shown in FIG. 1, the display sheet (A) constituting the display surface of the advertisement display device (B) is formed by joining four rectangular basic sheets (1) (1) having a predetermined width in this embodiment. As shown in FIG. 4, each of the basic sheets (1) is formed of a transparent vinyl chloride resin base material (17) and a transparent fluorine film (11) covering the surface of the base material (17). It consists of and.

The display sheet (A) is manufactured by the procedure shown in FIGS. As shown in Fig. 2, the basic sheet (1) with a certain width pulled out from the original roll (15) is cut into a certain length according to the size of the advertisement display device (B) to be manufactured, and the cutter (4) is provided. Be cut by. In this embodiment, the original roll 15 has a width of (cm).

Next, the fluorine film (11) located on the surface of one side of the basic sheet (1) is peeled off with a cutter (41) over a width of 2 mm to 5 mm, whereby a constant width of A polymerization charge (18) is formed. That is, the heat-resistant fluorine film (11) is peeled off to expose the heat-meltable base material (17). Next, on the polymerization margin (18) in the above-mentioned basic sheet (1), the side portions of the other base sheet (1) to be joined thereto are superposed, and further, on the back surface of the superposed portion. Overlay the translucent vinyl chloride backing tape (2). Then, when the polymerized portion is heated and pressed by a heating iron (5), the three basic sheets (1) and (1) and the back tape (2) that are stacked on top of each other are heat-welded, thereby adjoining the basic sheets. Sheets (1) (1) are joined. The reason why not only the above-mentioned basic sheets (1) and (1) are polymerized and welded to each other, but also the backing tape (2) is provided on the back side thereof is to secure sufficient bonding strength of the welded portions. Also, the width of the polymerized welded part of the basic sheet (1) (1) is set to 2 mm to 5 mm, whereby the above-mentioned polymerization is performed while securing the necessary binding force of the basic sheet (1) (1). This is to minimize the amount.

Next, as shown in FIG. 3, when the surface of the joint portion of the basic sheets (1) (1) is covered with a transparent adhesive tape (3) made of fluororesin, the adjacent basic sheets (1) ( The joining in 1) is completed. Then, by sequentially carrying out the same number of basic sheets (1) (1) that require such work, a display sheet (A) of the required size as shown in FIG. 1 is completed. In this product, the adhesive tape (3) is adhered to the surface of the joint portion of the basic sheet (1) (1) even if there is a minute gap in the joint portion of the basic sheet (1) (1). Therefore, there is less concern that dirt will enter the joint.

After that, when an advertisement display is attached to the surface of the display sheet (A) and the display sheet (A) is appropriately stretched on the frame body (C) of the advertisement display device (B), the advertisement display device (B) shown in FIG. Complete.
