TECHNICAL FlELD
[0001] The invention relates to modular panel walls with limited weight, which can be built
up simply and quickly without additional material requirements (in terms of tools).
PRIOR ART
[0002] Known systems exist in many forms and therefore have to deal with various problems.
[0003] A first series of systems is unwieldy and heavy, and so difficult to manipulate by
a user during erection or dismantling. Although this often ensures the stability of
the construction, it is detrimental to the efficiency of the erection, it is often
not ergonomically responsible, and it is more demanding in terms of material requirements
and there are many separate parts to be able to erect them. Moreover, for safety,
in such embodiments it will be necessary to anchor items to the floor, walls or other,
which in addition often requires additional tools.
[0004] Other systems aim to provide a lightweight solution, but lack stability. To make
them stand upright and stand still, the panels must then be fixed to another structure,
or hung, for example. This is not always possible (e.g. central positions separate
from walls or other structures, locations with wind or drafts, etc.). Moreover, during
fixation damage is often necessary to the panels in order to anchor them. Finally,
these panels are also often made to be disposed of after a single use.
[0005] The present invention aims to find a solution for at least some of the above problems.
By providing a lightweight structure, the panels can be easily erected. These panels
can be reused and recycled. The simple coupling method ensures that the panels are
erected without the need for loose parts or tools and thus not damaged during use.
In addition, the choice of structure also ensures that they are stable enough by themselves
not to require further suspension (unless, of course, very large structures are envisaged).
[0007] None of the existing systems combines all the advantages described above, without
including the associated disadvantages.

DETAILED DESCRIPTION OF THE INVENTION
[0010] Unless otherwise defined, all terms used in the description of the invention, including
technical and scientific terms, have the meaning as commonly understood by a person
skilled in the art to which the invention pertains. For a better understanding of
the description of the invention, the following terms are explained explicitly.
[0011] In this document, 'a' and 'the' refer to both the singular and the plural, unless
the context presupposes otherwise. For example, 'a segment' means one or more segments.
[0012] When the term 'around' or 'about' is used in this document with a measurable quantity,
a parameter, a duration or moment, and the like, then variations are meant of approx.
20% or less, preferably approx. 10% or less, more preferably approx. 5% or less, even
more preferably approx. 1% or less, and even more preferably approx. 0.1% or less
than and of the quoted value, insofar as such variations are applicable in the described
invention. However, it must be understood that the value of a quantity used where
the term 'about' or 'around' is used, is itself specifically disclosed.
[0013] The terms 'comprise', 'comprising', 'consist of', 'consisting of', 'provided with',
'have', 'having', 'include', 'including', 'contain', 'containing' are synonyms and
are inclusive or open terms that indicate the presence of what follows, and which
do not exclude or prevent the presence of other components, characteristics, elements,
members, steps, as known from or disclosed in the prior art.
[0014] In a first aspect, the invention relates to an assembly of two or more substantially
rectangular panels, suitable for the construction of temporary walls, preferably stand
construction and for events. In a preferred form, at least one side of the panels
is printable (suitable to be printed on), or coverable with a printed sheet / plate.
[0015] The panels each comprise two substantially rectangular, substantially rigid, flat
outer plates. The outer plates thus extend in a longitudinal and a transverse direction
perpendicular to each other in the plane of the outer plate. The two outer plates
are positioned parallel to each other, preferably as perpendicular projections onto
each other.
[0016] A, preferably substantially rectangular, intermediate structure is provided between
the two outer plates, although the shape may deviate from this. The intermediate structure
may consist of one or more substructures, preferably rectangular and provided along
the longitudinal axis with empty spaces therebetween. The intermediate structure has
a predetermined constant thickness and is substantially hollow and / or provided with
cavities. An example of this is multi-layered corrugated board. The intermediate structure
is attached to the inner side of both outer plates and extends longitudinally for
at least 75%, preferably at least 85%, of the length of the outer plates (longitudinal
dimension). The intermediate structure is not provided at the level of the longitudinal
ends (along the longitudinal axis) of the outer plates. The intermediate structure
here extends beyond the outer plates at a first transverse end over a distance A.
Preferably, the outer plates extend beyond the intermediate structure at the opposite
transverse end over a distance B approximately equal to distance A. It should be borne
in mind here that A and B are dimensioned so that the coupling elements of adjacent
panels fit perfectly, and the thickness of the coupling elements is not taken into
account.
[0017] The panels further comprise a first, rigid reinforcing element disposed between and
attached to the inner side of the outer plates at the first longitudinal end. The
first reinforcing element here extends transversely over at least 75% of the said
first longitudinal end. The reinforcing element is herein provided with a first coupling
element at a first end in the transverse direction, and a second coupling element
at the second opposite end in the transverse direction. The said coupling elements
are preferably hook-shaped and hook around an axis perpendicular to the panels, and
hook around an axis in the same sense.
[0018] The panels further comprise a second, rigid reinforcing element disposed between
and attached to the inner side of the outer plates at the second longitudinal end.
The second reinforcing element here extends transversely over at least 75% of the
said second longitudinal end.
[0019] The first coupling element is adapted to hook into a second coupling element of a
first adjacent panel, wherein the second coupling element is adapted to hook into
a first coupling element of a second adjacent panel.
[0020] Preferably one of the coupling elements is completely within the volume defined by
the outer plates, and the other coupling element is partially outside the volume defined
by the outer plates (at least the hook-shaped end of the other coupling element).
[0021] Said distance A is at least 1.0 mm, preferably at least about 2.5 mm. Said distance
B can be 0.0 mm or higher, since the play with the thickness of the coupling elements
allows them to fit perfectly together, as can be seen in the figures.
[0022] The proposed panels provide an easily erectable wall, which does not require any
tools for its construction. By simply hooking together, the connection is ensured,
and the panels cannot slide away from each other once aligned and anchored. The fact
that at a first transverse end, a recess is provided between the outer plates, and
at the opposite transverse end a portion is provided which protrudes from between
the outer plates and is dimensioned to fit in the recess provided, it is also ensured
that the panels fit together perfectly and cannot move relative to each other perpendicular
to the panels themselves. The protruding part (over a distance A) and the recess (depth
B which is at least as large as A) are complementary here. Together these factors
ensure a good anchoring, which additionally ensures the alignment of two adjacent
panels, and more specifically the outer plates.
[0023] The panel also makes good use of the two reinforcing elements, one at the top and
one at the bottom, to provide the coupling elements with a fixed anchoring, while
at the same time reinforcing the panels at the 'weakest' points, namely at the longitudinal
ends. In the centre, in the belly of the panel, it is thus sufficient to provide a
hollow intermediate structure, whereby the weight is greatly reduced, and yet the
desired strength is ensured.
[0024] In a preferred embodiment, the intermediate structure comprises corrugated board
with at least three layers, two of which are cover layers and a corrugated layer therebetween.
The cover layers are each attached to an outer plate on the inside thereof. The advantage
of corrugated board in such a form is that it offers sufficient strength - or can
easily be adapted for it - for a wall panel, and is extremely light. As a result,
one person can easily build a wall of panels in a very short time without additional
aids, and without experiencing physical discomfort (ergonomics). Moreover, such corrugated
cardboard is cheap, easy to process and easy to recycle.
[0025] In a preferred embodiment, the first coupling element is curved in a first sense
about an axis perpendicular to the panel, and the first coupling element extends transversely
beyond one of the transverse ends of the outer plates over a distance C. The second
coupling element is curved about the axis perpendicular to the panel in the first
sense, and is positioned transversely inward from the other transverse end of the
outer plates over a distance D. The distances C and D are herein substantially equal,
and the coupling elements are substantially at the same height along the longitudinal
axis.
[0026] The first coupling element is hook-shaped with the opening of the hook oriented in
a first sense along the longitudinal axis, and the second coupling element is hook-shaped
with the opening of the hook oriented in a second sense, opposite the first sense,
along the longitudinal axis. 'Opening of a hook-shaped element' here refers to the
concave side of the hook, as with the letter 'C' the opening would point to the right,
or as with the letter 'U' it would point upwards.
[0027] In the case of the panels, the openings of the coupling elements will be oriented
substantially up and down respectively.
[0028] With the above configuration it is possible to lift a panel and thus couple the coupling
element of the panel to the other coupling element of another panel. For example,
a part of the coupling element of the first-mentioned panel may have an end in the
shape of '∩', the coupling element of the other panel having a shape of 'U' at the
end. By sliding the first from above into the second, they can no longer slide apart
without deliberately lifting the panels apart. Because the anchoring takes place on
the basis of gravity, it is also easy to detach the panels from each other again through
a deliberate action. Due to the shape and positioning of the hooks, the panels are
pulled towards each other by gravity. The shape of the hooks is such that the panels
can be put together and taken apart with a slightly pivoting movement. This significantly
improves the ergonomics of placing and removing the panels.
[0029] In normal use of such wall panels, the main forces acting upon them are horizontal,
and it is especially important that the panels remain aligned and abut each other.
This is guaranteed by the above measures. In addition, by dimensioning the coupling
elements in such a way, it can be guaranteed that the panels connect in a predictable
manner, which makes it possible to provide the panels with a print or other visual
material that extends over several panels.
[0030] In a preferred embodiment, the outer plates extend longitudinally beyond the first
reinforcing element (lower) by a distance E, and wherein the second reinforcing element
extends longitudinally beyond the second (lower) longitudinal end of the outer plates
by a distance F, wherein the distance F is equal to or less than the distance E. Note
that variants are possible in which only the second reinforcing element extends longitudinally
beyond the second longitudinal end of the outer plates by a distance F.
[0031] The first variant also allows panels to be connected in the height direction, and
thus to work across multiple levels. The second variant is more suitable if single-layer
walls were opted for, but simplifies anchoring in the ground or a base due to the
availability of the second reinforcing element.
[0032] In a preferred embodiment, reinforcing layers are provided at both longitudinal ends
of the outer plates on the inside of the two outer plates. The reinforcing elements
are attached to the reinforcing layers, wherein the reinforcing layer extends over
substantially the width of the outer plates, preferably wherein the reinforcing layers
are the same material as the outer plates, more preferably with at least the same
thickness.
[0033] By specifically strengthening the outer plates at certain positions where more forces
are absorbed, the service life can be greatly increased, as well as an increased certainty
that the panels will not tear, break or be damaged in any other way during use or
installation.
[0034] In a further preferred embodiment, the reinforcing layer extends from the outer plates
a certain distance from the longitudinal ends, the intermediate structure extending
from the reinforcing layer of the first longitudinal end of the outer plates to the
reinforcing layer of the second longitudinal end of the outer plates.
[0035] In a preferred embodiment, the reinforcing layer extends from the longitudinal ends
of the outer plate a distance comprised between 3.0 cm and 10.0 cm, preferably between
4.0 cm and 7.0 cm, and more preferably about 5.0 cm; and wherein the reinforcing layer
preferably has a minimum thickness of 1.0 mm, preferably 2.0 mm, more preferably approximately
2.5 mm. The dimensions as indicated here ensure that the reinforcing layer can have
a sufficient effect, and moreover - as discussed further - can also assist in the
anchoring of the structures below or above.
[0036] In a preferred embodiment, the outer plates comprise recycled white paper, with a
minimum thickness of 1.0 mm, preferably 2.0 mm. Preferably the thickness is approximately
2.5 mm. The choice of recycled white paper is for its very easy printability. In addition,
by opting for a sufficiently thick plate, plates that have already been printed can
easily be 'erased' by sanding off a top layer thereof. This allows the plate to be
reused many times, where only one top layer is sanded each time. In existing systems,
either individual sheets are printed and attached to the panels, or the sheets are
simply disassembled and replaced with newly printed sheets.
[0037] Indeed, alternative materials for recycled white paper also fall within the invention,
preferably whereby the material allows a top layer to be easily sanded off for reuse.
[0038] In a preferred embodiment the intermediate structure has a thickness comprised between
20 mm and 50 mm, preferably between 25 mm and 45 mm, more preferably between 30 mm
and 40 mm. Preferably, the panels have a width comprised between 40 cm and 150 cm,
preferably between 50 cm and 100 cm. Preferably, the panels have a length comprised
between 100 cm and 350 cm, preferably between 150 cm and 300 cm. The above dimensions
provide an ideal balance of manoeuvrability, weight, erection efficiency, material
loss during erection and aesthetics (limitation of transitions).
[0039] In a most preferred embodiment, the length is about 240 cm, the width is about 60
cm, and the thickness is about 45 mm. However, variations on one or more of these
sizes are foreseeable, as these walls can easily be produced on request.
[0040] In a preferred embodiment, the coupling elements have a width between 15 mm and 50
mm, preferably between 20 and 40 mm, more preferably between 25 mm and 35 mm, and
most preferably about 30 mm. The width is the dimensions along the axis perpendicular
to the panels.
[0041] Preferably, the width of the coupling elements is approximately equal to the thickness
of the intermediate structure, possibly reduced by the thicknesses of the reinforcing
layers present there. By maximising the width of the coupling elements, applied forces
are better distributed and high local pressures are avoided that could potentially
lead to breakage or damage.
[0042] In a preferred embodiment, the second reinforcing element is provided with a male
positioning element at a first end on the transverse side of the panel. The second
reinforcing element is provided at a second end on the transverse side of the panel,
opposite the first end, with a female positioning element adapted to receive a male
positioning element from an adjacent panel. Preferably, the male positioning element
is a pin or other elongated element that projects transversely (i.e., in the plane
of the plate, perpendicular to the longitudinal axis). In that case, the female positioning
element is an opening dimensioned and suitable for receiving the male positioning
element. Preferably, this anchoring is substantially rigid to ensure that the positioning
elements must be deliberately uncoupled.
[0043] The positioning element offers two advantages. On the one hand, this is a reinforced
anchoring to absorb forces perpendicular to the panels, and then in particular in
a zone where the plates are less strongly attached (where the coupling elements at
the top still provide a stronger attachment). On the other hand, this also makes it
easier to print the panels continuously. The panels can be anchored together on a
printing path along which they are moved. In this way it can be guaranteed that the
printed panels align correctly in terms of image material thereon when setting them
up. With other systems it is often difficult to ensure high accuracy here, and poor
alignment is a common problem.
[0044] In a preferred embodiment, at least one of the panels is modified to serve as a corner
panel. In this case, another panel can be fixed at an angle of 90° or at a different
angle with respect to the corner panel. The corner panel is provided with a rigid
corner reinforcement on the inside of at least one of the outer plates over at least
part of its width. The corner reinforcement preferably has an L-shaped cross-section,
in which a first face of the L-shaped corner reinforcement is attached to the inside
of the outer plate, and a second face of the L-shaped corner reinforcement is attached
to the first reinforcing element.
[0045] The corner reinforcement is equipped with an anchorage extending perpendicular to
the outer plate and a downward hooking end piece suitable for anchoring to an upward
hooking coupling element of the other panel.
[0046] The attachment of the corner reinforcement to the reinforcing element provides structural
support for the corner reinforcement. Here, the corner reinforcement typically extends
over a length between 3.0 cm and 20.0 cm along the transverse direction, preferably
between 6.0 cm and 15.0 cm. The anchorage should not be present over the full length
of the corner reinforcement, and can only be over part of it, and is preferably dimensioned
to correspond in width to the thickness of the coupling elements / thickness of the
intermediate structure (as specified in the text). The anchorage extends from the
corner reinforcement over the outer plate, creating a hook that extends from the outer
plate and then extends downwards. The hook is positioned such that it can hook into
a coupling element of an adjacent plate that is directed upwards.
[0047] By providing these corner panels, more complex structures can be built, without the
panels having to be substantially changed. Instead of a coupling element, a corner
reinforcement is provided which comprises its own variant of a coupling element (anchorage/hook)
that can hook into a coupling element of an adjacent panel according to the same principles
as with the ordinary panels. In some variants, a corner panel can comprise both the
two coupling elements and the corner reinforcement, in order to make a T-shape that
can be expanded in all directions. The corner reinforcements can be made of metal
and/or comprise plastic, as well as other materials.
[0048] In a further preferred embodiment, the other panel is provided with two or more corner
connecting elements which protrude from the outer plates at the other transverse end.
Preferably, the corner connecting elements are substantially evenly distributed over
the transverse end of the panel. Preferably, the corner connecting elements protrude
from the outer plates over a maximum distance of 2.0 cm, preferably 1.5 cm or even
1.0 cm, 0.5 cm or less. These corner connecting elements can comprise wood, but also
plastic, synthetic material such as rubber, as well as other materials.
[0049] The above corner connecting elements serve, among other things, as a tongue for the
panel over which the groove is placed. This ensures the vertical stability of the
hookedin corner wall. The corner connecting elements have a width that fits into the
lateral recess of the panel connecting thereto, such that the corner connecting elements
are completely hidden therein, while at the same time preventing the movement of the
panel perpendicular to said panel.
[0050] In a preferred embodiment, the assembly comprises one or more end pieces that fit
into the lateral recesses in terms of width and length, and have a depth lower than
the dimension with which the recess is indented. These end pieces serve to close the
recess of the panels and give the impression that the recesses are not present.
[0051] In a preferred embodiment the assembly comprises one or more bases. The bases are
suitable for supporting the panels and anchoring a (lower) longitudinal end of the
panels, the bases having a substantially flat ground surface, for support on a substrate,
the bases comprising a top surface with a recess which runs from a first side face
of the base to a second opposite side face of the base. The recess is suitable for
receiving the (lower) longitudinal end of the panels. The side faces of the base connect
the ground surface and the top surface. The recess has a length substantially equal
to the transverse dimension of the panels, and a width substantially equal to the
thickness of the panels up to 25%, preferably up to 10%, more preferably up to 5%,
greater than the thickness of the panels.
[0052] Preferably, the recess extends over the entire top surface (from side face to side
face). In this way, panels can be placed over several successive bases, and panels
with a larger width can also be placed in one type of base.
[0053] Preferably, the width of the opening is substantially equal to the dimensions of
the panels in order to fix them as well as possible in a stable manner (no wobbling
walls). Certain widenings and narrowings can be provided in order to match even better
with the dimensions of the panels if necessary.
[0054] In a further preferred embodiment, the second reinforcing element extends longitudinally
beyond the second longitudinal end of the outer plates. The recess is stepped in a
first zone and a second zone, said first and second zones extending in sections parallel
to the ground surface, the first zone more distal relative to the ground surface than
the second zone. The recess has an opening in the first zone substantially equal to
the thickness of the panels up to 25%, preferably up to 10%, more preferably up to
5%, greater than the thickness of the panels. The recess has an opening in the second
zone substantially equal to the thickness of the second reinforcing element up to
25%, preferably up to 10%, more preferably up to 5%, greater than the thickness of
the second reinforcing element and wherein the recess in the second zone has an opening
lower than the thickness of the panels.
[0055] The above measures ensure good fixation at different levels, and also ensure that
the panels are all positioned at the same height, in order to correctly align any
printing.
[0056] In a preferred embodiment the bases are provided with two or more feet, which are
adjustable with respect to the ground surface of the base. This allows the bases to
be placed in a desired condition on uneven surfaces (or if a different position is
desired compared to a flat surface).
[0057] In a preferred embodiment, the coupling elements comprise a forked end, the forked
end comprising at least two, preferably two, fingers, the fingers being substantially
parallel to each other and extending at a distance from each other. This makes it
possible to allow cables and the like to pass through the recesses, wherein the cables
are moreover also fixed in terms of position. The opening between the fingers can
be quite limited, from 5 mm to 3 cm, but preferably between 0.75 cm and 2 cm.
[0058] In a preferred embodiment, the bases comprise two rigid slats, which slats are parallel
to each other and spaced from each other by one or more spacer elements, thus defining
the recess between the two slats.
[0059] In what follows, the invention is described by way of non-limiting examples illustrating
the invention, and which are not intended to and should not be interpreted as limiting
the scope of the invention.

EXAMPLES:
[0061] Figures 1-11 show views according to certain embodiments of the invention. Note that
most of the figures are similar, but can also be viewed separately from each other
(e.g. top views and bottom views, bases, etc.).
[0062] In some Figures, at least one of the outer plates, typically the one in front in
the line of sight, has been removed to reveal internal structures.
[0063] Figure 1 shows a panel (1) according to the invention, with the front outer plate
(2) removed. The intermediate structure (5) is visible here, which extends over a
large part of the height or length of the outer plate (2), but does not extend completely
to the top. A rigid reinforcing element (3) is provided at the top, typically wood,
although other materials are also possible. This reinforcing element extends over
most of the width of the panel, and is provided with coupling elements (4a, 4b) at
the lateral ends. The lateral ends are oriented to hook together (first on second)
at adjacent panels with the hook-shaped ends (8) of the coupling elements. This coupling
is more clearly visible in Figure 2.
[0064] The intermediate structure is approximately the same width as the outer plates, but
offset so that they protrude laterally relative to the outer plates on one side of
the panel and indent approximately the same distance on the other side. This allows
the panels to be joined, with the protruding intermediate structure sliding into the
recess of an adjacent panel.
[0065] Figure 3 shows a panel adapted to allow corner joints, in this case a right angle,
although other versions are possible. This is done by means of a specific corner reinforcement
(6) which is mounted on the outer plate and the reinforcing element, and allows another
(ordinary) panel to be hooked into with the coupling element (4a). In addition, corner
connecting elements (7) are provided on the corner panel to prevent damage.
[0066] Figure 10 shows a modified version of the corner reinforcement (6) with an anchoring
and downwards hooking end piece (18) suitable for anchoring to a coupling element
(4b).
[0067] Figure 4 shows a bottom side of panels according to the invention, in which the bottom
reinforcing elements (9) protrude at the bottom with respect to the outer plates.
This ensures that the stronger reinforcing elements are used for support, and can
also be useful when connecting to bases.
[0068] Figure 5 shows a detail of the top side of a panel, in which it is visible that at
the level of the reinforcing elements (9) a second reinforcing layer (10) is provided
on the outer plate (2), typically of the same material, this to reinforce this zone,
which has to handle more forces.
[0069] The thicknesses D1 and D2 are preferably equal and are preferably between 1.0 mm
and 5.0 mm, more preferably between 2.0 mm and 3.0 mm and most preferably about 2.5
mm.
[0070] The width B1 is preferably between 20 and 40 mm, more preferably about 30 mm; B2
preferably between 30 and 40 mm, and more preferably about 35 mm.
[0071] Figure 6 shows a detail of the underside of a panel and a base (1), the base comprising
two slats (12) interconnected by a number of spacer elements (13), which are themselves
provided with a base (15), preferably that can be slid out / is detachable by unscrewing.
The slats are provided on the top with a stepped recess (14) which allows to receive
a panel in the first zone, and is dimensioned in the deeper zone to receive only the
protruding portion of the second reinforcing element (9).
[0072] Figure 7 shows the possibility of a stacking of panels in the height direction, in
which a lower reinforcing element (9) can be received in a recess at the top of a
lower panel (1). Preferably, the lower reinforcing element (9) protrudes from the
outer plates (2) as far as the outer plates (2) extend from the upper reinforcing
element (3).
[0073] Figures 8 and 9 show the positioning elements (16, 17) provided on the lower fastening
elements (9) for aligning adjacent panels.
[0074] Figure 11 shows a detail drawing of an embodiment of the reinforcing elements (3)
with adapted coupling elements (4a, 4b), the coupling elements in this case comprising
two fingers (19) with a recess (20) between them, the recess suitable for allowing
passage of cables and the like.
1. Assembly of two or more substantially rectangular panels (1) for temporary walls,

a. two substantially rectangular, substantially rigid, planar outer plates (2) extending
in a longitudinal and transverse direction, and wherein the two outer plates are positioned
parallel to each other;

of a given thickness, the intermediate structures extending in the longitudinal and
