FOLDABLE DISPLAY MADE OF CORRUGATED CARDBOARD OR THE LIKE
Field of the Art
The present invention relates to a foldable display made of corrugated
cardboard or the like,
having a very simple and cost-effective construction and being easy and
practical to use, and which
in a working position provides a structure capable of standing upright on the
ground and provided
with one or more shelves for bearing items to be displayed.
Background of the Invention
Document US 2008/0265726 Al discloses a foldable display made of a single,
bent and
glued piece of corrugated cardboard or the like. The foldable display
comprises opposite front and
rear wall panels, opposite upper and lower panels connected in an articulated
manner to said front
and rear wall panels, a pair of side panels connected in an articulated manner
to the front wall panel,
and several shelf panels cut in the front wall panel and connected in an
articulated manner to the
front and rear wall panels. The front and rear wall panels, the upper and
lower panels and said shelf
panels form an articulated parallelogram configuration which can be moved
between a working
position wherein the upper and lower panels and the shelf panels are
perpendicular to the front and
rear wall panels, and a folded position wherein the front and rear wall
panels, the upper and lower
panels and the shelf panels are substantially parallel and superimposed. The
foldable display includes
foldable joint elements keeping the side wall panels coplanar with the front
wall panel in the folded
position, and retaining means formed by tabs projecting from the rear wall
panel and fitting and
interlocking in slits of the side wall panels in the working position.
A drawback of the foldable display of the mentioned document US 2008/0265726
Al is that
due to the existence of the mentioned foldable joint elements, the side wall
panels cannot be
additionally folded to reduce the extension of the display in the folded
position once the side wall
panels reach a position that is coplanar with the front wall panel.
Brief Description of the Invention
The present invention helps overcome the preceding and other drawbacks by
providing a
foldable display made of corrugated cardboard or the like comprising mutually
parallel and opposite
first and second wall panels, at least two mutually parallel connection
panels, each of which has a
first transverse edge connected in an articulated manner to said first wall
panel and a second
transverse edge connected in an articulated manner to said second wall panel,
where the first and
second wall panels and said at least two connection panels form an articulated
parallelogram
configuration which can be moved between a working position wherein the
connection panels are
CA 02910339 2015-10-23
2
perpendicular or inclined with respect to the first and second wall panels,
and a folded position
wherein the first wall panel and the connection panels are substantially
parallel to and superimposed
over an inner face of the second wall panel. The foldable display further
comprises at least one third
wall panel having an edge connected in an articulated manner to a first
longitudinal edge of the
second wall panel, and retaining means retaining said first, second and third
wall panels and the at
least two connection panels in said working position.
The mentioned third wall panel is foldable around said first longitudinal edge
between a
working position wherein the third wall panel is substantially perpendicular
or inclined with respect
to the first and second wall panels, closing a space defined between the first
and second wall panels
and the connection panels, and a folded position wherein the third wall panel
is substantially parallel
to and superimposed over an outer face of the second wall panel.
In one embodiment, the foldable display only has the mentioned third wall
panel in addition
to the first and second wall panels, and in such case the first and second
wall panels form side walls,
said third wall panel forms a rear wall, and at least one of said connection
panels forms a shelf.
In other embodiments, the foldable display includes a fourth wall panel having
a first
longitudinal edge connected in an articulated manner to a second longitudinal
edge of the second
wall panel opposite said first longitudinal edge, where the fourth wall panel
can be folded around
said second longitudinal edge between a working position wherein the fourth
wall panel is
substantially perpendicular or inclined with respect to the first and second
wall panels, closing a
space defined between the first and second wall panels and the connection
panels, and a folded
position wherein the fourth wall panel is substantially parallel to and
superimposed over an outer
face of the second wall panel together with the third wall panel in the folded
position.
In the case of including both third and fourth wall panels in addition to the
first and second
wall panels, the foldable display of the present invention can have two other
embodiments. In one
embodiment, the first wall panel forms a rear wall, the second wall panel
forms a front wall, the third
and fourth wall panels form side walls, and at least one of said connection
panels forms a shelf. In
another embodiment, the first wall panel forms a front wall, the second wall
panel forms a rear wall,
the third and fourth wall panels form side walls, and at least one of the
connection panels forms a
shelf.
Regardless of the embodiment of the foldable display of the present invention,
the second
wall panel has opposite inner and outer faces, and in the folded position the
third and fourth wall
panels are folded over the outer face of the second wall panel whereas the
articulated parallelogram
configuration formed by the first and second wall panels and the connection
panels is folded over the
CA 02910339 2015-10-23
3
inner face of the second wall panel. Therefore, the thickness of the first
wall panel and of the
connection panels in the folded position is not an obstacle for folding the
third and fourth wall panels,
and this allows reaching a significantly compact configuration in the folded
position.
In one embodiment in which the second wall panel forms a front wall, the
second, third and
fourth wall panels are integral parts of a first piece of sheet made of
corrugated cardboard or the like
cut from a previously printed first board of corrugated cardboard or the like.
Optionally, the
connection panels are also integral parts of said first piece of sheet and are
cut in the second wall
panel. In such case, the first transverse edge of each of the connection
panels is connected to a
respective fixing tab by a first weakened line, said fixing tab is fixed to
the first wall panel by fixing
means, and said second transverse edge of each of the connection panels is
connected to the second
wall panel by a second weakened line.
Alternatively, one or more of the connection panels are formed by additional
pieces of sheet
made of corrugated cardboard or the like, where the first transverse edge of
each of the connection
panels is connected to a first fixing tab by a first weakened line, said first
fixing tab is fixed to the
first wall panel by fixing means, said second transverse edge of each of the
connection panels is
connected to a second fixing tab by a second weakened line, and said second
fixing tab is fixed to the
second wall panel by fixing means. This allows including shelves formed by
connection panels with
a depth exceeding the vertical distance between shelves.
In one embodiment, the mentioned retaining means comprise a head piece having
first
retaining elements which fit and are interlocked in second retaining elements
formed in the third and
fourth wall panels when they are in the working position. This head piece is
made up of a second
piece of sheet made of corrugated cardboard or the like and can be cut from
said previously printed
first board of corrugated cardboard or the like together with said first piece
of sheet.
In an optional embodiment, the head piece is fixed to the first wall panel by
fixing means
and the first wall panel has a transverse fold line around which that portion
of the first wall panel in
which the head piece is fixed can be bent over an outer face of the rest of
the first wall panel in the
folded position.
In one embodiment in which the first wall panel forms a rear wall, which does
not need to be
printed, especially if the foldable display includes a printed head piece, the
first wall panel is formed
by a third piece of sheet made of corrugated cardboard or the like cut from a
non-printed second
board of corrugated cardboard or the like. This helps reduce the overall cost
of the product.
Preferably, in one embodiment in which the third and fourth wall panels are
side wall panels,
the latter have respective reinforcement panels adhered to their inner faces,
said reinforcement panels
CA 02910339 2015-10-23
4
having hooking elements attached thereto in an articulated manner by weakened
lines. These
hooking elements are not adhered to the corresponding third and fourth wall
panels, such that they
can pivot around the mentioned weakened lines. Furthermore, the foldable
display includes elastic
elements, such as rubber rings, each of which is connected to one of the
hooking elements of the
reinforcement panel adhered to the third wall panel and to one of the hooking
elements of the
reinforcement panel adhered to the fourth wall panel, such that the elastic
elements pull the third and
fourth wall panels towards the working position.
The hooking elements are strategically arranged in positions such that when
the foldable
display is in the working position, both the hooking elements and the elastic
elements are adjacent to
a lower face of the connection panels and are concealed by the latter.
Preferably, the third and fourth wall panels have upper edges connected to
respective flaps
by weakened lines, and said flaps are bent and adhered to an inner face of the
respective third and
fourth wall panels. In correspondence, the reinforcement panels have cutouts
in which the flaps fit.
The reinforcement panels are formed by respective fourth and fifth pieces of
sheet made of
corrugated cardboard or the like, and given that the reinforcement panels
generally do not need to be
printed, said fourth and fifth pieces of sheet are cut from said non-printed
second board of corrugated
cardboard or the like together with the third piece of sheet making up the
first wall panel.

Detailed Description of Embodiments
First in reference to the drawings, Figures 1 to 7 show a foldable display of
corrugated
cardboard or the like according to an embodiment of the present invention,
which comprises a first
wall panel 1 forming a rear wall of the foldable display and a second wall
panel 2 forming a front
wall of the foldable display. Said first and second wall panels 1, 2 are
opposite and mutually parallel,
and are connected to one another by three connection panels 5a, 5b, Sc forming
respective shelves.
The mentioned three connection panels 5a, 5b, Sc are mutually parallel, and
each of them has a first
transverse edge connected in an articulated manner to the first wall panel 1
and a second transverse
edge connected in an articulated manner to the second wall panel 2.
Therefore, the first and second wall panels 1, 2 and the three connection
panels 5a, 5b, Sc
form an articulated parallelogram configuration which can be moved between a
working position
(shown in Figure 1) wherein the connection panels 5a, 5b are perpendicular
with respect to the first
and second wall panels 1, 2, and a folded position (shown in Figure 7) wherein
the first wall panel 1
and the connection panels 5a, 5b are substantially parallel to and
superimposed over an inner face of
the second wall panel 2.
The foldable display of the embodiment shown in Figures 1 to 7 furthermore has
third and
fourth wall panels 3, 4 forming side walls of the foldable display. These
third and fourth wall panels
3, 4 have respective edges connected in an articulated manner to first and
second longitudinal edges
26, 27 opposite of the second wall panel 2, such that the third and fourth
wall panels 3, 4 are foldable
around said first and second longitudinal edges 26, 27 between a working
position (Figure 1)
wherein the third and fourth wall panels 3, 4 are substantially perpendicular
with respect to the first
and second wall panels 1, 2, closing a space defined between the first and
second wall panels 1, 2
and the connection panels 5a, 5b, and a folded position (Figure 7) wherein the
third and fourth wall
CA 02910339 2015-10-23
8
panels 3, 4 are substantially parallel to and superimposed over an outer face
of the second wall panel
2.
Given that, in the working position, the third and fourth wall panels 3, 4 are
perpendicular to
the first and second wall panels 1, 2, to go from the working position to the
folded position and vice
versa each of the third and fourth wall panels 3, 4 must perform a rotation of
2700 around the
respective first and second opposite longitudinal edge 26, 27 of the second
wall panel 2.
The foldable display of the embodiment shown in Figures 1 to 7 further
comprises retaining
means for retaining the first, second, third and fourth wall panels 1, 2, 3, 4
and the connection panels
5a, 5b, 5c in said working position. Said retaining means comprise a head
piece 32 which is placed
above the upper shelf in a position parallel and adjacent to the first wall
panel 1 forming the rear wall
of the foldable display. The mentioned head piece 32 has first projecting
retaining elements 33 which
fit and are interlocked in second retaining elements 34 in the form of a slit
formed in the third and
fourth wall panels 3, 4 when they are in the working position.
Furthermore, the foldable display of the embodiment shown in Figures 1 to 7
comprises first
and second reinforcement panels 37, 38 adhered to inner faces of the third and
fourth wall panels 3, 4,
respectively. These first and second reinforcement panels 37, 38 have hooking
elements 39 cut in
them which are attached thereto in an articulated manner by weakened lines 44,
such that said
hooking elements 39 can freely pivot with respect to the respective first and
second reinforcement
panels 37, 38 and corresponding third and fourth wall panels 3, 4.
The third and fourth wall panels 3, 4 have upper edges connected to respective
flaps 28, 29
by weakened lines 30, 31, and said flaps 28, 29 are bent and adhered to an
inner face of the
respective third and fourth wall panels 3, 4. In correspondence, the first and
second reinforcement
panels 37, 38 have cutouts 45, 46 in their upper edges in which the mentioned
flaps 28, 29 fit.
The retaining means additionally comprise elastic elements 70 (Figures 5, 6
and 7), such as
rubber rings, each of which is connected to one of the hooking elements 39
associated with the third
wall panel 3 and to one of the hooking elements 39 associated with the fourth
wall panel 4. The
hooking elements 39 are strategically arranged in the first and second
reinforcement panels 37, 38 in
positions selected such that when the foldable display is in the working
position, both the hooking
elements 39 and the elastic elements 70 are adjacent to a lower face of the
connection panels 5a, 5b,
Sc, so they are concealed by the connection panels 5a, 5b, Sc and not visible
in normal conditions.
As shown in Figure 2, the second, third and fourth wall panels 2, 3, 4 and the
connection
panels 5a, 5b, Sc are integral parts of a first piece of sheet 21 made of
corrugated cardboard or the
like. In the embodiment shown in Figures 1 to 7, the three connection panels
5a, 5b, Sc forming the
CA 02910339 2015-10-23
9
shelves are cut in the second wall panel 2, so the second wall panel 2 forming
the front wall is
reduced to three relatively narrow horizontal bands. The mentioned first
transverse edge of each of
the connection panels 5a, 5b, Sc is connected to a respective fixing tab 23 by
a first weakened line 24,
and said second transverse edge of each of the connection panels 5a, 5b, Sc is
connected to the
second wall panel 2 by a second weakened line 25.
When the foldable display is assembled, the fixing tabs 23 are fixed to the
first wall panel 1
forming the rear wall by fixing means, such as an adhesive reinforced with
rivets going through
corresponding die-cut holes 53, 54 in the fixing tabs 23 and in the first wall
panel 1, respectively, for
example. The mentioned holes 53, 54 make the operation of positioning the
fixing tabs 23 with
respect to the first wall panel 1 during a gluing operation significantly
easier.
In the embodiment shown in Figures 1 to 7, the second weakened lines 25
connecting the
second transverse edge of each of the connection panels 5a, 5b, Sc with the
corresponding horizontal
band of the second wall panel 2 are located in the upper edge of the
horizontal band of the second
wall panel 2, such that in the working position (Figure 1), the upper edge of
each horizontal band is
flush with the upper surface of the corresponding connection panel 5a, 5b, Sc.
The head piece 32 is made up of a second piece of sheet 22 made of corrugated
cardboard or
the like. Both first and second pieces of sheet 21, 22 are preferably cut from
a first board of
corrugated cardboard or the like 20 a face of which has been previously
printed, such that the printed
surface will be visible on the outer faces of the second, third and fourth
wall panels 2, 3, 4 forming
the front and side walls, respectively, on the upper faces of the connection
panels 5a, 5b, Sc forming
the shelves, on the inner faces of the flaps 28, 29 of the third and fourth
wall panels 3, 4, and on the
front face of the head piece 32.
As shown in Figure 3, the first wall panel 1 forming the rear wall and the
first and second
reinforcement panels 37, 38 are formed by respective third, fourth and fifth
pieces of sheet 41, 42, 43
made of corrugated cardboard or the like, and said third, fourth and fifth
pieces of sheet 41, 42, 43
are cut from a second board of corrugated cardboard or the like 40, which does
not have to be printed.
Therefore, the visible surfaces of the foldable display that will not be
printed on are the inner and
outer faces of the first wall panel 1 forming the rear wall and the inner
faces of the first and second
reinforcement panels 37, 38 adhered to the third and fourth wall panels 3, 4
forming the side walls.
It will be understood that the number of connection panels 5a, 5b, Sc can
vary, although at
least two are essential. Furthermore, given that in this embodiment the
connection panels 5a, 5b, Sc
forming the shelves are cut from the second wall panel 2 forming the wall
front, there is a
proportionality between the depth of the shelves and the vertical separation
distance between the
CA 02910339 2015-10-23
horizontal bands making up the second wall panel 2, which together with the
vertical height of the
horizontal bands making up the second wall panel 2, can condition the number
of shelves in the
foldable display.
Figures 8 to 10 show another embodiment of the foldable display of the present
invention,
which is similar to the embodiment described above in relation to Figures 1 to
7, including a first
piece of sheet 21 (Figure 9) made of corrugated cardboard or the like
integrating the second, third
and fourth wall panels 2, 3, 4 and the connection panels 5a, 5b, Sc cut in the
second panel 2, a second
piece of sheet 22 (Figure 9) made of corrugated cardboard or the like
integrating the head piece 32,
and third, fourth and fifth pieces of sheet 41, 42, 43 (Figure 10) made of
corrugated cardboard or the
like integrating the first wall panel 1 and the first and second reinforcement
panels 37, 38,
respectively.
The first and second pieces of sheet 21, 22 are preferably cut from a first
board of corrugated
cardboard or the like 20 a face of which has been previously printed, and the
third, fourth and fifth
pieces of sheet 41, 42, 43 are preferably cut from a non-printed second board
of corrugated
cardboard or the like 20.
The embodiment shown in Figures 8 to 10 differs from the embodiment shown in
Figures 1
to 7 in that the second weakened lines 25 connecting the second transverse
edge of each of the
connection panels 5a, 5b, Sc with the corresponding horizontal band of the
second wall panel 2 are
located at the lower edge of the horizontal band of the second wall panel 2.
This difference means
that in the working position (Figure 8), the lower edge of each horizontal
band is flush with the lower
surface of the corresponding connection panel 5a, 5b, 5c, and accordingly the
horizontal bands of the
second wall panel 2 form railings or protective walls for the connection
panels 5a, 5b, 5c forming the
shelves.
The working of the foldable display according to the embodiment shown in
Figures 8 to 10
during folding and unfolding operations is similar to the working described
above in relation to
Figures 4 to 7.
Figures 11 and 12 show yet another embodiment of the foldable display of the
present
invention, which is similar in its entirety to the embodiment described above
in relation to Figures 8
to 10, except in that in this case one of the connection panels, and more
specifically the connection
panel Sc forming the lower shelf, is not integrated in the first piece of
sheet 21 but rather is made up
of an additional piece of sheet 47, which is preferably cut together with the
first and second pieces of
sheet 21, 22 from a first board of corrugated cardboard or the like 20 a face
of which has been
previously printed.
CA 02910339 2015-10-23
11
This additional piece of sheet 47 comprises the corresponding connection panel
5c, a first
fixing tab 48 connected by a first weakened line 49 to said first transverse
edge of the connection
panel 5c and a second fixing tab 50 connected by a second weakened line 51 to
said second
transverse edge of the connection panel 5c. When the foldable display is
assembled, said first fixing
tab 48 is fixed to the first wall panel 1 by fixing means and said second
fixing tab 50 is fixed to the
second wall panel 2 by fixing means.
In the embodiment shown in Figures 11 and 12, the foldable display comprises a
first wall
panel 1 and first and second reinforcement panels 37, 38 similar to those
described above in relation
to Figure 10, which can be cut from a non-printed second board of corrugated
cardboard or the like
40.
The working of the foldable display according to the embodiment shown in
Figures 11 and
12 during folding and unfolding operations is similar to the working described
above in relation to
Figures 4 to 7.
Although in the embodiment shown in Figures 11 and 12 the connection panel Sc
formed by
the additional piece of sheet 47 separated from the first piece of sheet 21 is
the connection panel
forming the lower shelf, it will be understood that any of the connection
panels 5a, 5b, Sc could be
formed by a corresponding separate additional piece of sheet 47, and even
several or all of the
connection panels 5a, 5b, Sc of the foldable display could be formed by
respective separate
additional pieces of sheet 47. Therefore, the depth of the shelves formed by
the connection panels
does not have to be proportional to the vertical distance between the
horizontal bands of the second
wall panel 2 forming the front wall, and the opening of the second wall panel
2 between two
connection panels can even be omitted.
Figures 13 to 18 show a foldable display according to yet another embodiment
of the present
invention, which is similar in its entirety to the embodiment described above
in relation to Figures 8
to 10, except in that in this case the head piece 32 is fixed to an upper
region 36 of the first wall
panel 1 by fixing means. To that end, the mentioned upper region 36 of the
first wall panel 1 forming
the rear wall has side protrusions 35 (Figure 13) reproducing the shape of the
first retaining elements
33 of the head piece 32. Once the head piece 32 is fixed to the first wall
panel 1 (Figure 14), the first
retaining elements 33 of the head piece 32 are superimposed over and adhered
to said side
protrusions 35 of the first wall panel 1.
Furthermore, the first wall panel 1 has a transverse fold line 52 around which
an upper
portion of the first wall panel 1 in which the head piece 32 is fixed can be
bent towards the folded
position (Figure 15). Therefore, in the folded position, the upper portion of
the first wall panel 1 and
CA 02910339 2015-10-23
12
the head piece 32 are parallel to and superimposed over a rear surface of the
rest of the first wall
panel 1.
Figure 16 shows the foldable display provided with the first wall panel 1
fixed to the head
piece 32 of Figures 14 and 15 in a position prior to the working position
wherein the connection
panels 5a, 5b, 5c are in a position perpendicular to the first and second wall
panels 1, 2 and the third
and fourth wall panels 3, 4 are in a position perpendicular to the connection
panels 5a, 5b, 5c and to
the first and second wall panels 1, 2, although the mentioned upper portion of
the first wall panel 1
with the head piece 32 are bent backwards.
In Figure 17 the upper portion of the first wall panel 1 with the head piece
32 has been lifted
until being located almost in the same plane as the rest of the first wall
panel 1 and the entire first
wall panel 1 and head piece 32 assembly has been lifted off the ground a
sufficient distance so that
the first retaining elements 33 of the head piece 32 can pass over the upper
edges of the third and
fourth wall panels 3, 4. The lifting of the first wall panel 1 causes a
temporary inclination of the
connection panels 5a, 5b, Sc.
In Figure 18 the upper portion of the first wall panel 1 has been slightly
tilted until aligning
the first retaining elements 33 of the head piece 32 with the second retaining
elements 34 of the third
and fourth wall panels 3, 4, and the first wall panel 1 with the head piece 32
has then been lowered
until fitting the first retaining elements 33 of the head piece 32 with the
second retaining elements 34,
whereby the connection panels 5a, 5b, Sc recover their horizontal position and
the third and fourth
wall panels 3, 4 are held in the working position.
Given that the connection panels 5a, 5b, Sc are connected to the first wall
panel 1, and that
the side protrusions 35 of the first wall panel 1 superimposed over and
adhered to the first retaining
elements 33 of the head piece 32 are fitted in the second retaining elements
34 of the third and fourth
wall panels 3, 4 in the working position, part of the weight of the items
borne on the connection
panels 5a, 5b, Sc is transmitted to the third and fourth wall panels 3, 4, the
strength of which is
increased as a result of the first and second reinforcement panels 37, 38
adhered thereto.
Figure 19 shows a variant of the first wall panel 1 and head piece 32 assembly
described
above in relation to Figures 13 to IS, where a lower region of the first wall
panel 1 is shortened such
that a lower edge 55 of the first wall panel 1 is at a distance D1 above a
position H in which it would
theoretically have to be in so that the connection panels 5a, 5b, Sc were
horizontal in the working
position, taking into account that the positions in which the connection
panels 5a, 5b, Sc are
connected to the first wall panel 1, which are preferably determined by the
positions of the holes 54
through which rivets are optionally installed, have not been modified.
CA 02910339 2015-10-23

Figure 20 shows the effect of using the first wall panel 1 and head piece 32
assembly
according to the shortened variant of Figure 19 in a foldable display like the
one in Figure 1, where
said shortened distance D1 causes the rear edges of the connection panels 5a,
5b, Sc to be at a lower
level than the front edges, and accordingly causes the connection panels 5a,
5b, 5c to be inclined
backwards and downwards. This inclination of the shelves and the first wall
panel 1 prevents given
items, such as bottles displayed on the shelves, for example, from falling.
Figure 21 shows a variant of the first wall panel 1 and head piece 32 assembly
described
above in relation to Figures 13 to 15, where a lower region of the first wall
panel 1 is elongated such
that a lower edge 55 of the first wall panel 1 is at a distance D2 below a
position H in which it would
theoretically have to be in so that the connection panels 5a, 5b, Sc were
horizontal in the working
position, taking into account that the positions in which the connection
panels 5a, 5b, Sc are
connected to the first wall panel 1, which are preferably determined by the
positions of the holes 54
through which rivets are optionally installed, have not been modified.
Figure 22 shows the effect of using the first wall panel 1 and head piece 32
assembly
according to the elongated variant of Figure 21 in a foldable display like the
one in Figure 8, where
said elongated distance D2 causes the rear edges of the connection panels 5a,
5b, Sc to be at a higher
level than the front edges, and accordingly causes the connection panels 5a,
5b, Sc to be inclined
forwards and downwards. The railings or protective walls formed by the
horizontal bands of the
second wall panel 2 prevent items displayed on the shelves, such as flexible
containers, for example,
from falling.
It will be understood that the shortened and elongated variants of the first
wall panel 1
described above can also be applied even though the head piece 32 is not fixed
to the first wall panel
1.
In relation to Figures 23 to 29, now there is described a foldable display
made of corrugated
cardboard or the like according to an additional embodiment of the present
invention which, in a
manner similar to the embodiments described above, comprises first, second,
third and fourth wall
panels 1, 2, 3,4 and two connection panels 5a, 5b, where the first and second
wall panels 1, 2 and the
connection panels 5a, 5b form an foldable articulated parallelogram
configuration.
As shown in Figure 23, in the working position the first wall panel 1 forms a
rear wall, the
second wall panel 2 forms a front wall, the third and fourth wall panels 3, 4
form side walls, and one
of said connection panels 5a, which is located in an upper position, forms a
shelf whereas the other
one of the connection panels 5b, which is located in a lower position (not
shown in Figure 23)
performs a merely structural function.

the second wall panel 2
by respective weakened lines 26, 27. The head piece 32 integrated in the
second piece of sheet 22
includes first projecting retaining elements 33 which are superimposed over
said side protrusions 35
when the head piece is adhered to said upper region 36 of the first section la
of the first wall panel 1.
The third and fourth wall panels 3, 4 have upper prolongations which in the
working position
(Figure 23) are adjacent to the first wall panel 1 forming the rear wall of
the foldable display and
reach a height proportional to the height of the first wall panel I. In the
first piece of sheet 21 (Figure
25), the third and fourth wall panels 3, 4 have upper edges connected to
respective flaps 28, 29 by
weakened lines 30, 31, and in the display said flaps 28, 29 are bent and
adhered to an inner face of
the respective third and fourth wall panels 3, 4. Furthermore, second
retaining elements 34 in the
form of a slit in which said first retaining elements 33 of the head piece 32
in the working position fit,
are formed at the upper edges of the third and fourth wall panels 3, 4.
Figure 26 shows a non-printed second board of corrugated cardboard or the like

front edge connected to a fixing tab 58 by a weakened line 59. The third
section 1 c of the first wall
panel 1 has an upper edge connected to a fixing tab 60 by a weakened line 61.
In the fourth and fifth pieces of sheet 42, 43 (Figure 26), each of said first
and second
reinforcement panels 37, 38 has a fixing portion provided for being fixed to
an inner face of the
corresponding third and fourth wall panel 3, 4 and an hooking element 39 which
is attached in an
articulated manner to the rest of the reinforcement panel 37, 38 by a weakened
line 44, such that said
hooking elements 39 can freely pivot with respect to the respective first and
second reinforcement
panels 37, 38 and corresponding third and fourth wall panels 3, 4. The lower
connection panel 5b has
side recesses 62 the purpose of which is to allow tilting of the hooking
elements 39 of the first and
second reinforcement panels 37, 38 during folding and unfolding operations of
the display and to
house these hooking elements 39 in the working position.
Figure 24 illustrates the assembly of the first, second, third, fourth and
fifth pieces of sheet
21, 22, 41, 42, 43 for forming the foldable display of the embodiment shown in
Figures 23 to 29. To
that end, the fixing tab 58 of the third piece of sheet 41 is adhered to an
inner face of the second wall
panel 2 of the first piece of sheet 21 such that an outer face of the lower
connection panel 5b is flush
with a lower edge of the second wall panel 2, and the fixing tab 60 of the
third piece of sheet 41 is
adhered to an inner face of the upper connection panel 5a of the first piece
of sheet 21 such that an
outer face of the third section lc of the first wall panel 1 is aligned with
an outer face of the second
section lb of the first wall panel 1.
Furthermore, the head piece 32 of the third piece of sheet 41 is adhered to
the upper region
36 of the first section 1 a of the first wall panel 1, and the fixing portions
of the first and second
reinforcement panels 37, 38 of the fourth and fifth pieces of sheet 42, 43 are
adhered to the inner
faces of the third and fourth wall panels 3, 4 of the first piece of sheet 21.
Furthermore, elastic
elements 70, such as rubber rings, are installed engaging the hooking elements
39 of the first and
second reinforcement panels 37, 38.
Figures 27 to 29 illustrate folding and unfolding operations of the display of
the embodiment
shown in Figures 23 to 29, which are similar to those described above for
other embodiments. In the
folded position shown in Figure 29, the first section la of the first wall
panel 1 with the head piece
32 are bent backwards over the outer face of the second and third sections 1
b, 1 c of the first wall

In relation to Figures 30 to 34, now there is described a foldable display
according to another
additional embodiment of the present invention providing a pedestal, and
comprising mutually
parallel first and second wall panels 1, 2 which, unlike the preceding
embodiments, in a working
position (Figure 30) form front and rear walls, respectively, third and fourth
wall panels 3, 4 which
in the working position form opposite side walls, and three mutually parallel
and superimposed
connection panels 5a, 5b, Sc, the upper connection panel 5a of which in the
working position forms
an upper shelf of the pedestal, the intermediate connection panel 5b forms a
lower shelf and the
lower connection panel Sc performs a merely structural function. The first
wall panel 1 has a window
63 through which the lower shelf is accessed.
Each of the three connection panels 5a, 5b, Sc has a front edge connected in
an articulated
manner to the first wall panel 1 and a rear edge connected to the second wall
panel 2, such that the
first and second wall panels 1, 2 and the three connection panels 5a, 5b, 5c
form an articulated
parallelogram configuration which can be moved between a working position
(Figure 30) wherein
the three connection panels 5a, 5b, Sc are perpendicular with respect to the
first and second wall
panels 1, 2, and a folded position (Figures 33 and 34) wherein the first wall
panel 1 and the three
connection panels 5a, 5b, Sc are substantially parallel to and superimposed
over an inner face of the
second wall panel 2.
The third and fourth wall panels 3, 4 have respective vertical edges connected
in an
articulated manner to first and second opposite vertical edges of the second
wall panel 2, such that
the third and fourth wall panels 3, 4 are foldable around said first and
second vertical edges between
the working position (Figure 30) wherein the third and fourth wall panels 3, 4
are substantially
perpendicular with respect to the first and second wall panels 1, 2, closing a
space defined between
the first and second wall panels 1, 2 and the connection panels 5a, 5b, Sc,
and the folded position
(Figures 33 and 34) wherein the third and fourth wall panels 3, 4 are
substantially parallel to and
superimposed over an outer face of the second wall panel 2.
In the inner faces of the third and fourth wall panels 3, 4 there are hooking
elements 39, and
an elastic element 70, such as a rubber ring, engages the hooking elements 39
to pull the third and
fourth wall panels 3, 4 towards the working position, thereby constituting
retaining means retaining
the display in the working position. The mentioned elastic element 70 is
located between the
intermediate connection panel 5b and the lower connection panel Sc such that
it is concealed in the
working position.
The upper connection panel 5a is sized such that it laterally projects in the
working position
(Figure 30) from the first, second, third and fourth wall panels 1, 2, 3, 4
and is supported on the
CA 02910339 2015-10-23
17
upper edges thereof. Furthermore, at least the upper connection panel 3a and
the first, second, third
and fourth wall panels 1, 2, 3, 4 are made from several pieces of sheet of
corrugated cardboard or the
like having considerable thickness, so the pedestal can bear an item to be
displayed having a
relatively heavy weight.
In relation to Figures 35 to 38, now there is described a foldable display
according to yet
another additional embodiment of the present invention comprising mutually
parallel first and
second wall panels 1, 2 which, unlike the preceding embodiments, form side
walls in a working
position (Figure 30), a third wall panel 3 which forms a rear wall in the
working position, and three
mutually parallel and superimposed connection panels 5a, 5b, Sc forming three
respective shelves. In
this embodiment, the fourth wall panel has been omitted.
Each of the three connection panels 5a, 5b, 5c has a front edge connected in
an articulated
manner to the first wall panel 1 and a rear edge connected to the second wall
panel 2, such that the
first and second wall panels 1, 2 and the three connection panels 5a, 5b, Sc
form an articulated
parallelogram configuration which can be moved between a working position
(Figure 35) wherein
the connection panels 5a, 5b, Sc are perpendicular with respect to the first
and second wall panels 1,
2, and a folded position (Figure 38) wherein the first wall panel 1 and the
three connection panels 5a,
5b, Sc are substantially parallel to and superimposed over an inner face of
the second wall panel 2.
The third wall panel 3 has a vertical edge connected in an articulated manner
to one of the
opposite vertical edges of the second wall panel 2, such that the third wall
panel 3 is foldable around
the mentioned vertical edge between the working position (Figure 35) wherein
the third wall panel 3
is substantially perpendicular with respect to the first and second wall
panels 1, 2 providing a rear
wall for the shelves formed by the connection panels 5a, 5b, Sc, and the
folded position (Figure 38)
wherein the third wall panel 3 is substantially parallel to and superimposed
over an outer face of the
second wall panel 2.
In the inner faces of the second and third wall panels 2, 3 there are hooking
elements 39.
Elastic elements 70, such as rubber rings, at one end engage the hooking
elements 39 connected to
the second wall panel 2 and at the other end engage the hooking elements 39
connected to the third
wall panel 3, such that they pull the third wall panel 3 towards the working
position, thereby
constituting retaining means retaining the display in the working position.
The mentioned elastic
elements 70 are located adjacent to the lower faces of the connection panels
5a, 5b, Sc such that they
are concealed by same in the working position.
Figure 39 shows a foldable display according to yet another additional
embodiment of the
present invention, which is similar in its entirety to the embodiment
described above in relation to
CA 02910339 2015-10-23
18
Figures 1 to 7, except in that the first and second wall panels 1, 2 forming
the rear and front walls,
respectively, and the connection panels 5a, 5b, 5c forming the shelves are
buckled. More specifically,
the rear and front walls are convex with respect to the front part of the
display and the shelves are
concave with respect to the upper part thereof. These concave shelves formed
by the buckled
connection panels 5a, 5b, Sc are suitable for given items to be displayed,
such as bottles lying
horizontally, for example. In Figure 39, the head piece 32 has been omitted
for greater clarity of the
drawing.
Figure 40 shows a first piece of sheet 21 made of corrugated cardboard or the
like, which
integrates the second, third and fourth wall panels 2, 3, 4 and the connection
panels 5a, 5b, 5c. The
first piece of sheet 21 is similar to the described above in relation to
Figure 2, except in that the first
weakened lines 24 connecting the first transverse edge of each of the
connection panels 5a, 5b, 5c to
the respective fixing tab 23 to be fixed to the first wall panel 1 and the
second weakened lines 25
connecting the second transverse edge of each of the connection panels 5a, 5b,
5c to the
corresponding horizontal band of the second wall panel 2 are concave with
respect to the upper part
thereof, and this determines that the first and second wall panels 1, 2 and
the connection panels 5a,
5b, 5c adopt a buckled configuration when the connection panels 5a, 5b, Sc are
moved from the
folded position to the working position.
In the foldable display of Figure 39, the first wall panel 1, the
reinforcement panels 37, 38
and the head piece 32, as well as the working of the display during folding
and unfolding operations,
are similar to those described above in relation to Figures 1 to 7.
Figure 41 shows a foldable display having a trapezoidal footprint the basic
structure of
which can be according to any of the embodiments of the foldable display of
the present invention
described up until now, or combinations thereof, in which the horizontal width
of the first wall panel
1 forming the rear wall is less than the horizontal width of the second wall
panel 2 forming the front
wall, and the connection panels 5a, 5b, Sc, 5d are trapezoid-shaped.
Accordingly, the third and fourth
wall panels 3, 4 adopt inclined positions with respect to the first and second
wall panels 1, 2 without
this affecting the general working of the display during folding and unfolding
operations.
Figure 42 shows a plan view of a possible grouping of eight of the displays
having a
trapezoidal footprint of Figure 41 to form an octagonal display island
covering 360 . Obviously other
groupings with a different number of displays and covering other angles are
possible. By changing
the angles of the trapezoidal configuration of the display, groupings of a
different number of displays,
even covering 360 , can be formed. It will be understood that the
configuration having a trapezoidal
CA 02910339 2015-10-23
19
footprint can be applied to a foldable display according to any of the
possible embodiments of the
present invention.
It will be understood that some of the features described above in association
with one of the
embodiments of the present invention can also be applied to other embodiments
of the present
invention, and that two or more of the embodiments of the present invention
can be combined with
one another to give rise to new variants.
It must be pointed out that the panels forming the foldable display according
to any possible
embodiment of the present invention can be separate pieces of sheet or can be
grouped in pieces of
sheet different from that described above. Likewise, the different pieces of
sheet can be obtained
from one or more boards of corrugated cardboard or the like, which can all be
previously printed, or
one or more can be previously printed and one or more non-printed, and they
can even all be non-
printed.
Figures 43 to 46 and Figures 47 to 50 illustrate a simple hinge element 64 and
a complex
hinge element 65, respectively, which can be applied to a foldable display of
corrugated cardboard or
the like according to any one of the possible embodiments of the present
invention, especially if a
corrugated cardboard having considerable thickness is used in the construction
thereof, although they
can also be applied to any other construction made of pieces of sheet of
corrugated cardboard or the
like attached in an articulated manner.
The mentioned simple and complex hinge elements 64, 65, which are shown in
their
extended positions in Figures 43 and 47, respectively, comprise a strip of
flexible material, such as a
plastic, a plasticized paper, a textile, a plasticized textile, and the like,
showing good tear and fatigue
fracture strength when it is repeatedly bent in opposite directions along a
bend line.
As shown in Figure 43, the simple hinge element 64 has a single central bend
line 66
longitudinally splitting the strip in two halves. In use, the simple hinge
element 64 is bent along said
central bend line 66 (Figure 44), and one of the halves of the strip is
adhered to a first piece of sheet
A and the other one of the halves of the strip is adhered to a second piece of
sheet B.
Figure 45 shows an application of the simple hinge element 64 where the halves
of the strip
are adhered to the first and second pieces of sheet A, B in positions such
that the central bend line 66
is adjacent to an edge of the first piece of sheet A and spaced from an edge
of the second piece of
sheet B. This arrangement allows a relative rotation of 90 between a position
wherein the first and
second pieces of sheet A, B are mutually parallel and superimposed (on the
left side of Figure 45)
and a position wherein the first and second pieces of sheet A, B are mutually
perpendicular and a
CA 02910339 2015-10-23
portion of the second piece of sheet B is supported on a flat edge of the
first piece of sheet A (on the
right side of Figure 45).
Figure 46 shows another application of the simple hinge element 64 where the
halves of the
strip are adhered to the first and second pieces of sheet A, B in positions
such that the central bend
line 66 is adjacent to respective edges of both first and second pieces of
sheet A, B. This
arrangement allows a relative rotation of 180 between a position wherein the
first and second pieces
of sheet A, B are mutually parallel and superimposed (on the left side of
Figure 46) and a position
wherein the first and second pieces of sheet A, B are mutually aligned and a
flat edge of the second
piece of sheet B is supported on a flat edge of the first piece of sheet A (on
the right side of Figure
46).
As shown in Figure 47, the complex hinge element 65 has two parallel bend
lines 67, 68
longitudinally splitting the strip in two end thirds and a central third. In
use, the complex hinge
element 65 is bent along both bend lines 67, 68 (Figure 48), and one of the
end thirds of the strip is
adhered to a first piece of sheet A and the other one of the end thirds of the
strip is adhered to a
second piece of sheet B.
Figure 49 shows an application of the complex hinge element 65 where the
surfaces of one
and the same face of the two end thirds of the strip are adhered to flat edges
of the first and second
pieces of sheet A, B. This arrangement allows a relative rotation of 270
between a position wherein
the first and second pieces of sheet A, B are mutually perpendicular, with the
flat edge of the second
piece of sheet B supported on a face of the first piece of sheet A (on the
left side of Figure 49), and a
position wherein the first and second pieces of sheet A, B are mutually
parallel, whether they are
superimposed (in the top right part of Figure 49) or spaced apart by the width
of the central third of
the strip (in the bottom right part of Figure 49).
Figure 50 shows an application of the complex hinge element 65 where the
surfaces of
opposite faces of the two end thirds of the strip are adhered to flat edges of
the first and second
pieces of sheet A, B. This arrangement allows a relative rotation of 360
between a position wherein
the first and second pieces of sheet A, B are mutually parallel and
superimposed (on the left side of
Figure 50), and a position wherein the first and second pieces of sheet A, B
are likewise parallel and
superimposed, although in inverse positions (on the right side of Figure 50).
The main advantage of the simple and complex hinge elements 64, 65 described
above is
that they provide hinged attachments between pieces of sheet of corrugated
cardboard or the like
without having to use weakened lines, for example score lines, crushing the
internal structure of the
CA 02910339 2015-10-23
21
corrugated cardboard or the like and destroying its strength capacity at the
crushed edges, conserving
flat edges capable of providing firm support for other adjacent pieces of
sheet.
Figures 51 to 54 illustrate another additional embodiment of the foldable
display of the
present invention, which is essentially identical to the embodiment described
above in relation to
Figures 1 to 7, except in that the foldable display of Figures 51 to 54
includes a base platform panel
71 connected in an articulated manner to lower ends of the first and second
wall panels 1, 2 by
means of a base connection panel 72 and an elastic band 73. The mentioned base
platform panel 71
has dimensions greater than the footprint of the foldable display in the
working position (Figure 51)
to provide additional stability to the display.
The base platform panel has cutouts 74 defining hooking elements 75 (Figure
52) which, in
the working position, are inscribed within the footprint of the foldable
display and accordingly
concealed. The base connection panel 72 has at two of its opposite ends
attachment flaps 76 provided
for being adhered to the first and second wall panels 1, 2, and at the other
two opposite ends cutouts
defining corresponding hooking elements 77 which are conjugated with the
mentioned hooking
elements 75 of the base platform panel 71 when the base connection panel 72 is
superimposed over
the base platform panel 71.
In an operative situation (Figure 53), the attachment flaps 76 of the base
connection panel 72
are bent upwards and adhered to the lower edges of the first and second wall
panels 1, 2 such that the
base connection panel 72 is substantially flush with the ground. The elastic
band 73, which is in the
form of a rubber ring, for example, is arranged above the base connection
panel 72 and engaging at
the ends thereof both the hooking elements 77 of the base connection panel 72
and the hooking
elements 75 of the base platform panel 71 to connect the base platform panel
71 to the foldable
display (Figure 53).
Figure 54 shows the foldable display in the folded position, which is similar
to the one
described above in relation to the embodiment of Figures 1 to 7, although here
the base platform
panel 71 slightly projects from the sides and below the rest of superimposed
panels of the foldable
display.
The scope of the present invention is defined in the attached claims.
