Description

1. FIELD OF THE INVENTION

This invention relates to display devices, which permit quick and ready replacement of an advertisement display subject or the like, such as a painting, an ink drawing, a photograph, a poster, etc. More particularly, the invention concerns display devices, which permit quick and ready replacement of such display subject as a painting, an ink drawing, a photograph, etc. according to the taste of a visitor or to match the installation place such as home, shop, etc., or of an advertisement display subject according to an advertisement patron change or an advertisement content change. As for the device construction, the devices permit maintaining neat and stable display state without fall-down or deviation of the painting, ink writing, photograph, etc. and without possibility of peel-off of the advertisement display subject.

2. PRIOR ART

In the prior art, the replacement, if necessary, of a painting, an ink writing, a photograph, etc. framed in a frame member, the frame is first taken out from a wall surface, then it is disassembled into its components, i.e., a base plate, a painting subject, a mat framing the painting subject, a glass (or transparent synthetic resin) plate and a frame member, then the old painting subject is taken out, then the replacement painting, ink writing, photograph, etc., is set on the base plate, then the frame is assembled again by making time-consuming accurate positioning of it, and finally the base plate and the most front frame member are coupled together into an integral frame by using coupling members. This operation requires great man-hour.

In the case of a signboard or the like, a wide and long poster preliminarily printed is bonded on the surface of a signboard frame with a powerful adhesive uniformly lest irregularities or peel-off should be generated. This operation also inevitably requires great man-hour, and also requires prudence and skill.

In the case of the frame replacement, the operation is very cumbersome; that is, the frame is taken out from a wall surface, then the painting is replaced by a disassembling operation, then the frame is reassembled by making accurate positioning, and finally the base plate and the frame member are made integral by using coupling members. Therefore, despite the fact that it is ideal to make the painting subject replacement whenever required to match the season, according to the taste of a visitor or for other reasons, in many cases this is not actually done due to its cumbersomeness.

In the case of the signboard replacement, lest the bonded poster is peeled off or has irregularities, it is necessary to apply adhesive uniformly to the poster back surface, and also air should be eliminated from the back surface side of the poster. Therefore, a bonding operation requiring prudence and skill should be made by an operator having special skill. This means that the replacement of the advertisement requires great man-hour and much expenditure. For this reason, despite the fact that the replacement of the advertisement display subject leads to improved advertising effect, in many cases this is not made.

Up to date, a magnetically attachable magnetic sheet laminate for display has been developed, which has a thickness of about 0.2 mm and comprises a thin-film-like magnetic sheet and an impression sheet constituted by a synthetic resin film and laminated on one surface of the magnetic sheet. This magnetic sheet laminate permits very ready printing of a display subject such as a painting, an ink drawing, a photograph, an advertisement, etc. on the surface of the impression sheet with such printing machine as a copier, a printer, a plotter, etc.

In addition, with recent development of copying and printing techniques, it has become possible to produce a display subject, which is magnetically attachable and can be erroneously thought to be a real painting, ink drawing, photograph, etc. or to be a clear and impressive advertisement poster or the like.

SUMMARY OF THE INVENTION

A first object of the invention is to provide a display device, which permits a painting, an ink drawing, a photograph, etc. in a frame member to match the taste of painting, ink drawing, photograph, etc. to match the season and place of installation and according to the taste of a visitor.

A second object of the invention is to provide a display device, which concerns signboard advertisement and permits quick and ready replacement of the advertisement display subject according to an advertisement patron change or an advertisement content change and without need of much expenditures or any operation by a skilled operator.

A third object of the invention is to provide a display device construction, which permits a frame to be always held displayed in a neat and stable state without possibility of deviation or fall-down of the displayed painting or display thereof not in an accurate set position, and also permits a signboard to be held free from the possibility of peel-off of the advertisement display subject of generation of irregular surfaces to make the subject less comfortable to view and also to be readily peeled off at the time of the display subject replacement without accompaniment of any remaining adhesive, and thus providing for sufficient effects of outdoor or like advertising function.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

FIGS. [0022] 1 to 3 shows a first embodiment of the display device, in which the display member is a frame. As shown, in this display device 1, a thin-film-like impression sheet 3 constituted by a paper or synthetic resin film with a thickness of 0.1 to 0.2 mm is laminated on one surface of a thin-film-like magnetic sheet 2 with a thickness of 0.1 to 0.2 mm, a display subject 4 such as a painting, an ink drawing, a photograph, an advertisement, etc. is printed on the surface of the impression sheet 3 by using such a printer as a copier, a plotter, a printer, etc., and this magnetic sheet laminate is detachably magnetically attached to the surface of a magnetic member 5 of a base plate 6, the magnetic member 5 being provided on the surface of the base plate 6 and constituted by steel, steel paper, etc. Reference numeral 7 designates a frame member, which has a magnet 8 provided on its back surface for being detachably magnetically attached to the edge of the base plate 6. Reference numeral 9 designates a glass or transparent synthetic resin protective plate which is provided on the inner side of the frame member 7. The protective plate 9 has functions of protecting the display subject 4 and preventing attachment of dust particles to the display subject 4 and also has an effect of providing for improved aesthetic sense of the display subject 4 or the whole frame.
FIG. 4 shows a magnetic sheet laminate, which is obtained by laminating an [0023] impression sheet 3 on one surface of the magnetic sheet 2 and printing a display subject such as a painting, an ink drawing, a photograph, an advertisement, etc. on the surface of the impression sheet 3. Reference numeral 10 designates a coating layer, which serves to improve the slip of the magnetic attachment surface of the magnetic sheet 2 and preventing the transfer of the display subject.
The [0024] display device 1 comprising the above components is assembled as follows. In the first place, the base plate 6 is secured to a wall or the like. Then, the magnetic sheet 2 bearing the impression sheet 3, which has the drawing, ink writing, photograph, advertisement, etc. printed on one surface of it, is positioned and magnetically attached to the magnetic member 5 of the base plate 6. Then, the magnet 8 of the frame member 7, in which the glass or transparent synthetic resin plate 9 is fitted, is magnetically attached to the outer side of the magnetic sheet 2. In this way, the display device 1 with the display subject framed therein as shown in FIG. 2 can be readily obtained. In this embodiment, the magnetic sheet 2 has a size, which is selected to be equal to or slightly greater than the inner size of the frame member 7, it is also possible that the size of the magnetic sheet 2 is slightly less than the inner side of the frame member 7. Also, in case of dispensing with the glass or transparent synthetic resin plate 9, it is possible to magnetically attach and detach the magnetic sheet 2 with the frame member 7 held magnetically attached to the magnetic member 5 of the base plate 6.
FIGS. [0025] 5 to 7 shows a second embodiment of the display device according to the invention. In this display device 11, a mat 12 is interposed between the display subject 4 and the glass or transparent synthetic resin plate 9 in the first embodiment of the display device 1. This mat 2 is formed from a thick paper board by cutting off a window portion, which corresponds to the display subject 4 such as the painting, ink drawing, photograph, advertisement, etc. so that the display subject 4 can be seen through the window. The mat 12 thus frames and shows up the display subject 4. While the mat 12 may be provided on the inner side of the frame member 7, it may also be clamped between the magnet 8 in the back side of the frame member 7 and the magnetic member 5 of the base plate 6 if it is thin enough.
FIG. 8 is an actual arrangement of the second embodiment. In this example of the [0026] display device 11, a magnet 13 is provided on the back surface of the base plate 6. With the magnet 13 provided on the back surface of the base plate 6, the device 11 can be readily magnetically attached to the wall surface, which is preliminarily provided with a magnetic member surface of a steel partition or the like.
FIG. 9 shows a third embodiment of the display device according to the invention. In this [0027] display device 14, a display sheet 15 which bears a display subject such as a painting, an ink writing, a photograph, etc. is a paper or synthetic resin sheet without any magnetically attaching property. A magnetic member 17 which is capable of being magnetically attached to a magnet 8 mounted on a frame member 7, is disposed on only the edge of base plate 16 on the side of the frame member. The display sheet 15 is secured to the base plate 16 via such intervening members as a mat 12 in contact with the edge of the display sheet 15 and glass or transparent synthetic rein plate 9.
Again in this embodiment, like the previous embodiments, it is possible to quickly and readily replace the display subject. [0028]
FIG. 10 shows a fourth embodiment of the display device according to the invention. This [0029] display device 18 concerns a signboard 20, which is to be installed as outdoor or like display and has a magnetic surface 19 of steel or the like. The signboard 20 is a laminate, in which an impression sheet bearing an impression of an advertisement is laminated on a magnetic sheet, and it is detachably magnetically attached. The laminate comprising the impression sheet and the magnetic sheet, as in the previous embodiment, is obtained by laminating a thin-film-like impression sheet 3 constituted by a paper or synthetic resin film with a thickness of 0.1 to 0.2 mm on one surface of a thin-film-like magnetic sheet 2 with a thickness of 0.1 to 0.2 mm. An advertisement is printed as display subject 4 on the surface of the impression sheet 3 by using a plotter or the like. A double-side bond tape 22 with peel-off sheet 21 is applied to the edge of the other surface, i.e., magnetic attachment surface, of the magnetic sheet 2.
The [0030] display device 18 having the above construction is assembled as follows. In the first place, the double-side bond tape 22 with peel-off sheet 21 is applied to the edge of the magnetic attachment surface of the magnetic sheet 2, on which the impression sheet 3 with the advertisement displayed on the surface is laminated. Then, the magnetic sheet 2 with peel-off sheet 21 is roughly positioned and magnetically attached to the signboard 20 with the magnetic surface 19 of steel or the like. Then, for accurately positioning it to the signboard 20 and mounting it thereto, it is partly peeled off the magnetic surface 19 of the signboard 20 and moved. When the display subject is accurately positioned, the peel-off sheet 21 of the double-side bond tape 22 is peeled off while a little peeling off the edge of the magnetic sheet 2 lest the magnetic sheet 2 should be deviated in position. The double-side bond tape 22 is applied one side after another, for instance. Such display device 18, even installed in an outdoor place subject to rains and winds, is free from such possibility that the end of the magnetic sheet 2 is tore or peeled off by winds, and the display subject can be steadily provided. In addition, since the magnetic sheet 2 is bonded only along its edge, when it becomes necessary to change the advertisement display subject, the magnetic sheet 2 can be quickly and readily peeled off the signboard 20, and the display subject can be readily replaced.
Although not shown, it is conceivable in the case of a large signboard to form a single display subject by applying together a plurality of magnetic sheets. In this case, it is required to accurately make not only the positioning of the magnetic sheet to the signboard but also the display matching of adjacent magnetic sheets. In this embodiment of the [0031] display device 18, in the assembling method as described above the double-side bond tape is positioned with the peel-off sheet held attached to it, and then it is bonded by peeling off the peel-off sheet. Thus, it is possible for any one to accurately make the positioning and display matching.
In the double-[0032] side bond tape 22, it is preferred to set the adhesion of the adhesive on the side of the magnetic surface 19 to be less than the adhesion of the adhesive on the side of the magnetic sheet 2. By so doing, the double-side bond tape 22 can be readily peeled off when replacing the display subject. In addition, it is possible to prevent the adhesive to remain on the magnetic surface 19, thus alleviating the very time-consuming operation of removing the remaining adhesive after the peel-off.
FIG. 11 shows a fifth embodiment of the display device according to the invention. In this display device [0033] 23, the display member is a vehicle 24 such as a car, a train, etc. (a car in this embodiment) having a magnetic surface, and a magnetic sheet with a display subject is provided on the body of the car. The magnetic sheet as laminate with the display subject, like the preceding third embodiment of the display device 23, is obtained by laminating a thin-film-like impression sheet 3 on one surface of a thin-film-like magnetic sheet 2 and printing an advertisement display subject 4 on the surface of the impression sheet 3 by using a plotter or the like. Moreover, a double-side bond tape with peel-off sheet is applied to the edge of the other surface, i.e., magnetic attachment surface, of the magnetic sheet. In this embodiment, three magnetic sheet laminates are used from the consideration of the disposition of doors of the car and so forth.
This display device [0034] 23 is assembled as follows. In the first place, a magnetic sheet laminate bearing the double-side bond tape with peel-off sheet is positioned with respect to a lap part of the impression tape 3, and is magnetically attached. Then, the adjacent magnetic sheet laminate is magnetically attached by positioning it with respect to the display of a lap part of the impression sheet 3. The magnetic sheet laminates are successively magnetically attached by peeling off the peel-off sheets of the double-side bond tapes on their back side with the mark displays of their impression sheets 3 in right positions. Thus, it is possible for any one to complete the display member without need of any professional skill. In addition, since the display device according to the invention has flexibility, it is possible to set the display member appropriately on even a body having irregular or curved surfaces without shrinkage or stress generation.
In the prior art frame replacement, the frame member is removed from wall surface or the like, the painting or the like is replaced by the disassembling operation, and finally the base plate and the frame member are made integral by using a coupling member. This replacement operation is very cumbersome. Therefore, despite that it is ideal to replace the painting or the like whenever desired for every season, according to the taste of a visitor and for other reasons, in many cases no replacement is made due to cumbersomeness at the time of replacement. According to the invention, it is possible to provide a frame, which permits simple, quick and ready replacement of the display subject such as a painting, an ink writing, a photograph and so forth to match the season or the place of disposition or according to the taste of a visitor. [0035]
In case of providing not only the base plate front surface and the frame member back surface but also the base plate back surface with a magnet capable of being magnetically attached to the steel or like magnetic member surface, the frame can be readily magnetically attached to a wall surface, which is preliminarily provided with a surface of a magnetic member such as a steel partition member, without use of any hook or like attaching member for securing the frame to the wall surface. [0036]
In the case of a signboard, in order to uniformly coat adhesive to the back surface of the poster and also precluding air from the back side of the poster lest the bonded poster should have irregularities, a prudent and skilled bonding operation by an operator having special skill is necessary. The replacement of the advertisement thus requires great man-hours and much expenditure. Therefore, despite the fact that the advertising effect can be improved by replacing the advertisement display subject, in many cases no replacement is made. According to the invention, when it becomes necessary to change the advertisement display subject, any one can quickly and readily replace the poster or the like without need of conventional professional ability. [0037]
In the case with the display member constituted by a vehicle such as a car, a train, etc., a magnetic sheet laminate having an impression sheet surface with an advertisement displayed thereon is detachably magnetically attached to a magnetic surface of the vehicle. Thus, the replacement of the advertisement display subject, when necessary, can be made quickly and readily, and the advertising effect can be provided more efficiently. [0038]
Furthermore, by applying the double-side bond tape with peel-off sheet to the edge of magnetically attaching surface of the magnetic sheet laminate with the advertisement displayed on the impression sheet surface, it is possible to move and position the magnetic sheet laminate magnetically attached to the display member by utilizing the magnetically attaching action of the detachably attachable and movable magnetic sheet laminate and then bond the double-side bond tape by peeling off the peel-off sheet. Thus, any one can quickly, readily and accurately position the magnetic sheet laminate without need of any conventional professional skill. [0039]
Still further, when forming a large-size advertisement display subject such as an advertisement poster with a plurality of continuous magnetic sheet laminates with an advertisement displayed on the impression sheet surfaces, by applying a double-side bond tape with peel-off sheet to the edge if the magnetically attaching surface of each magnetic sheet laminate, it is possible to move and position the magnetic sheet laminates magnetically attached to the display member by utilizing the magnetically attaching action of the detachably attachable and movable magnetic sheet laminates and then bond each double-side bond tape by peeling off the peel-off sheet. Thus, any one can quickly and readily and accurately, i.e., without deviation, match adjacent magnetic sheet laminates without need of any conventional professional skill. [0040]
As for the adhesive of the double-side bond tape, in order that the tape can be easily peeled off from the magnetic surface of steel or the like and that no adhesive remains on the magnetic surface, the adhesion of the adhesive on the magnetic sheet surface side is set to be less than the adhesion of the adhesive of the magnetic surface side. By so doing, the double-side bond tape can be readily peeled off at the time of the display subject replacement. Also, it is possible to eliminate any adhesive remaining on the magnetic surface and alleviate a very time-consuming operation of removing any remaining adhesive after the peel-off. [0041]
