DISPLAY DEVICE
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.,
1
CA 02389403 2002-06-05
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 banded 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
2
i
CA 02389403 2002-06-05
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,
4
CA 02389403 2002-06-05
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. 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
6
i, i
CA 02389403 2002-06-05
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 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.

CA 02389403 2002-06-05
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
of the base plate 6.
Figs. 5 to 7 shows a second embodiment of the display
device according to the invention. In this display device
8
i
CA 02389403 2002-06-05
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 $ 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 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 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
9
i
CA 02389403 2002-06-05
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.
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
i
CA 02389403 2002-06-05
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 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
11
i ...
CA 02389403 2002-06-05
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 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-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,
12
i i
CA 02389403 2002-06-05
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 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 23 is assembled as follows. In
the first place, a magnetic sheet laminate bearing the
13
i
CA 02389403 2002-06-05
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
14
CA 02389403 2002-06-05
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.
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.
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,
CA 02389403 2002-06-05
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.
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.
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
16
CA 02389403 2002-06-05
need of any conventional professional skill.
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.
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
17
e
CA 02389403 2002-06-05
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.
