Description
1. FIELD OF THE INVENTION
[0001] 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
[0002] 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.
[0003] 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.
[0004] 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.
[0005] 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.
[0006] 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.
[0007] 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
[0008] 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.
[0009] 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.
[0010] 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
[0022] FIGS. 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.
[0023] FIG. 4 shows a magnetic sheet laminate, which is obtained by
laminating an 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.
[0024] The 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.
[0025] FIGS. 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.
[0026] FIG. 8 is an actual arrangement of the second embodiment. In
this example of the 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.
[0027] FIG. 9 shows a third embodiment of the display device
according to the invention. In this 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.
[0028] Again in this embodiment, like the previous embodiments, it
is possible to quickly and readily replace the display subject.
[0029] FIG. 10 shows a fourth embodiment of the display device
according to the invention. This 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.
[0030] The 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.
[0031] 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 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.
[0032] In the double-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.
[0033] FIG. 11 shows a fifth embodiment of the display device
according to the invention. In this display device 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.
[0034] This display device 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.
[0035] 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.
[0036] 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.
[0037] 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.
[0038] 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.
[0039] 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.
[0040] 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.
[0041] 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.
