Description

Foldable display structure comprising tray supports forming structural reinforcement

The invention relates to the field of cardboard and point-of-sale advertising, commonly referred to by the acronym “POS”.

The invention relates more specifically to a foldable display structure.

State of the prior art

Document FR 2 679 521 A1 describes a foldable display structure which is part of the prior art. This structure is made from a cardboard panel with cutouts and folding lines allowing the structure to be volumetric for use.

In this area, there is a need to improve display structures in order to reduce their bulk during transport while simplifying their volume.

For this purpose, the invention relates to a foldable display structure comprising two side walls and at least one support element, the support element comprising a central part and two side parts configured to each cooperate with a respective one of the side walls in order to be able to maintain the support element in a receiving position in which it is capable of supporting a tray arranged on its central part, each of the side walls comprising at least a first part and a second part connected to one another the other by at least one folding line configured to allow movement of the side wall between a first position, in which the first part is folded against the second part, and a second position, the structure being configured to be able to be placed in a configuration of use in which the side walls are in the second position and in which the support element is in the receiving position. According to the invention, when the structure is in use configuration, the side parts of the support element are each arranged facing the first part and the second part of the side wall with which it cooperates so as to oppose a movement of the side walls from the second position to the first position.

Side walls comprising such a folding line make it possible to easily modify the configuration of the structure and in particular the arrangement of the side walls. When the side walls are in said first position, that is to say when said first part is folded over said second part, the structure is folded and thus presents a reduced bulk which in particular facilitates its transport. To bring the structure into volume in order to place it in the configuration of use from such a transport configuration, the placement of the side walls in said second position can be carried out by simply unfolding the side walls.

The invention makes it possible to take advantage of the principle of changing the configuration of the structure by folding/unfolding the lateral parts while ensuring reinforced maintenance of the structure in use configuration.

Indeed, in use configuration, the side parts of the support element are each arranged facing the first part and the second part of the side wall with which it cooperates. Thus, the side part of the support element which cooperates with a first of the side walls is arranged facing the first part and the second part of this first side wall, while the side part of the support element which cooperates with the second side wall is arranged opposite the first part and the second part of this second side wall. In other words, in use configuration, the lateral parts of the support element are arranged on the side walls so as to extend on either side of the folding line, thus opposing folding of the lateral parts along said folding line and thus ensuring that the side walls are maintained in said second position and, consequently, of the structure in the configuration of use.

The support element thus constitutes a structural reinforcement which makes it possible to avoid unwanted folding or sagging of the side walls when the structure is in use configuration.

The invention also makes it possible, more generally, to reinforce the structural strength and to increase the admissible loading of the structure.

In one embodiment, each of the side walls comprises at least one cutout configured to receive one end of the side part of the support element which cooperates with this side wall when the structure is in use configuration.

Preferably, for each of the side walls, said end of the side wall forms a tongue.

In one embodiment, said cutout and said folding line of each of the side walls are spaced from one another in a direction orthogonal to a plane in which the central part of the support element extends when that -this is in the receiving position.

In one embodiment, each of the lateral parts of the support element comprises a reinforcing part connected on the one hand to said end which it forms by a first folding line and on the other hand to the central part of the support element by a second folding line.

The first fold line and the second fold line of each of the side parts are preferably parallel.

Of course, in the context of this embodiment, the first folding line and the second folding line of each of the lateral parts of the support element can be oblique relative to each other, depending on example of the geometry of the support element and/or the side walls of the structure.

In one embodiment, said folding line of each of the side walls passes through a plane parallel to a plane in which the central part of the support element extends when it is in the receiving position.

In one embodiment, each of the side walls includes an inner layer and an outer layer which are superimposed relative to each other when the side walls are in the second position.

Preferably, each of the lateral parts of the support element, where appropriate said reinforcing part of this lateral part, rests on a surface formed by the internal layer of the side wall with which this lateral part cooperates when the structure is in use configuration.

In one embodiment, for each of the side walls, the internal layer forms said cutout.

In one embodiment, for each of the side walls, the outer layer forms said fold line.

Preferably, for each of the side walls, the internal layer comprises a cutting line which is superimposed on the folding line when this side wall is in the second position.

In one embodiment, for each of the side walls, said folding line of this side wall is a first folding line, and the inner layer and the outer layer are connected to each other by at least a second line folding.

The second folding line may be oblique or, more preferably, perpendicular to the first folding line.

In one embodiment, the structure is configured to form several floors, said first part of the side walls delimiting one of these floors and said second part of the side walls delimiting another of these floors when the structure is in use configuration .

The invention also relates to a display comprising a structure as defined above.

In one embodiment, the display comprises at least one tray configured to be able to be placed on the at least one support element when the structure is in the configuration of use.

Preferably, the at least one tray is removable.

The display can also include a covering, covering for example part of the structure in order to improve the structural strength of the display and/or its aesthetic appearance.

According to another aspect, the subject of the invention is a method for creating volume of a structure as defined above.

In one embodiment, this method comprises positioning the side walls in said second position and positioning the at least one support element in said receiving position.

According to another aspect, the invention relates to a method for changing the configuration of a structure as defined above.

In one embodiment, this method comprises folding or unfolding the side walls so as to pass the structure from one to the other among said use configuration and a transport configuration.

Detailed description of embodiments

He is represented on the a display stand 1 according to the invention in a configuration of use, also called "presentation configuration", in which it forms a generally rectangular parallelepiped piece of furniture extending vertically.

In this example, the display 1 comprises an internal structure 2, also called a “frame”, which is represented separately on the and described in more detail below with reference to Figures 2 to 5.

Display 1 of the also includes a covering 3 partially enveloping the structure 2, as well as removable trays 4.

In presentation configuration, the structure 2 and the covering 3 form two side walls 5 and 6, a rear wall 7 and a perforated front wall 8.

In this example, the rear wall 7 is formed by the structure 2, the front wall 8 is formed by the covering 3, while the side walls 5 and 6 are each formed both by the structure 2 and by the covering 3.

The front wall 8 comprises sections 10 spaced vertically from each other and delimiting front openings 11.

In presentation configuration, each of the trays 4 extends to the right of a respective section 10 so that the front openings 11 allow a user to view and/or take articles (not shown) placed on the trays 4 .

In this non-limiting example, the display 1 comprises four trays 4 which each define a respective one of the levels of this display.

In reference to the , the structure 2 comprises support elements 16-19 configured to be connected to the side walls 5 and 6 and to the rear wall 7 formed by this structure 2 so as to be able to each support a respective one of the trays 4 of the display 1.

The structural and geometric characteristics of panels 30, 60 and 90 will now be described, with reference to Figures 3 to 5, making it possible to form structure 2 of display stand 1.

In this example, the panels 30, 60 and 90 are made of cardboard and each include cutouts and/or cutting lines, as well as fold lines. In Figures 3 to 5, the cuts and cutting lines are shown in solid lines while the folding lines are shown in broken lines. Of course, these panels 30, 60 and 90 may include cutouts and/or cutting lines and/or additional folding lines.

Figures 3 to 5 show the panels 30, 60 and 90 in a flat configuration, that is to say in which they are neither folded nor put into volume.

In this flat configuration, each of the panels 30, 60 and 90 comprises two parallel surfaces defining between them a thickness of these panels. By convention, for each of the panels 30, 60 and 90 of Figures 3 to 5, the surface visible in these figures is called "first surface" and the opposite surface, not visible in these figures, is called "second surface".

In the following, in the absence of contrary indications, an element is said to be vertical or horizontal by reference to the orientation of this element when the structure 2 that it constitutes is in presentation configuration.

In reference to the , the panel 30 comprises seventeen parts 31-47 connected to each other by vertical folding lines LP1-LP16: the parts 31 and 32 are connected to each other by the folding line LP1, the parts 32 and 33 are connected to each other by the folding line LP2, the parts 33 and 34 are connected to each other by the folding line LP3, the parts 34 and 35 are connected to each other to each other by the folding line LP4, the parts 35 and 36 are connected to each other by the folding line LP5, the parts 36 and 37 are connected to each other by the line of folding LP6, parts 37 and 38 are connected to each other by the folding line LP7, parts 38 and 39 are connected to each other by the folding line LP8, parts 39 and 40 are connected to each other by the folding line LP9, the parts 40 and 41 are connected to each other by the folding line LP10, the parts 41 and 42 are connected to each other other by the folding line LP11, the parts 42 and 43 are connected to each other by the folding line LP12, the parts 43 and 44 are connected to each other by the folding line LP13, parts 44 and 45 are connected to each other by the folding line LP14, parts 45 and 46 are connected to each other by the folding line LP15, and parts 46 and 47 are connected to each other by the fold line LP16.

Parts 33 and 37 each include four cutouts 50, or “openings”, which in this example form generally horizontal grooves. For each of the parts 33 and 37, the openings 50 are vertically spaced from each other. The openings 50 of part 33 and the openings 50 of part 37 are horizontally aligned two by two. Vertically, the openings 50 of part 33 are aligned with each other, each having an edge aligned with the fold line LP3. The openings 50 of part 37 are also vertically aligned with each other.

Parts 41 and 45 are symmetrical with respect to parts 37 and 33, respectively, and therefore also include openings 50 (see ).

Part 39, also called “central part”, comprises two openings 51 and two openings 52 which each extend generally horizontally.

The part 38 comprises three openings 54 which each extend generally vertically and which are vertically spaced from each other. Each of the openings 54 of part 38 extends substantially along the fold line LP8.

Part 40 being symmetrical to part 38, the latter also includes three openings 54.

The panel 30 further comprises horizontal folding lines LP21-LP26 and horizontal cutting lines LD1-LD6 crossing the panel 30 horizontally so as to define a vertically lower part P1, a vertically middle part P2 and a vertically upper part P3 formed each by respective parts of parts 31-47.

The lower part P1 and the middle part P2 of the panel 30 are connected to each other by the folding lines LP21-LP23, while the upper part P3 and the middle part P2 are connected to each other by folding lines LP24-LP26.

More precisely, with reference to the , the folding line LP21 connects the lower part P1 and the middle part P2 of the part 35 of the panel 30 to each other and, symmetrically, the lower part P1 and the middle part P2 of the part 43 of the panel 30 .

The cutting line LD1 extends in continuity with the folding line LP21 so as to delimit the lower part P1 and the middle part P2 of the parts 31-34 of the panel 30 and, symmetrically, the lower part P1 and the middle part P2 of parts 44-47.

The cutting line LD2 extends in continuity with the folding line LP21 so as to delimit the lower part P1 and the middle part P2 of the part 36 and a first portion of the part 37 of the panel 30 and, symmetrically , the lower part P1 and the middle part P2 of part 42 and a first portion of part 41.

The folding lines LP22 and LP23 extend vertically on either side of a fictitious line passing through the lines LD1, LD2, LD3 and LP21 so as to vertically define two intermediate portions 59 between them. The folding line LP22 delimits the middle part P2 and a first of the intermediate portions 59 formed by a second portion of the part 37, the part 38 and a first portion of the central part 39 of the panel 30 and, symmetrically, the middle part P2 and the second intermediate portion 59 formed by a second portion of the part 41, the part 40 and a second portion of the central part 39 of the panel 30. Concerning the folding line LP23, this delimits the lower part P1 and the first intermediate portion 59 formed by said second portion of part 37, part 38 and said first portion of the central part 39 of the panel 30 and, symmetrically, the lower part P1 and the second intermediate portion 59 formed by said second portion of part 41, part 40 and said second portion of the central part 39 of the panel 30.

Said intermediate portions 59 are delimited by vertical cutting lines LD7 extending from the folding line LP22 to the folding line LP23 so that these cutting lines LD7 each join a respective end of the cutting lines LD2 and LD3 (see ).

The preceding description relating to the delimitation of the lower part P1 with respect to the middle part P2 applies by analogy to the delimitation of the upper part P3 with respect to the middle part P2, the assembly formed by the fold lines LP24-LP26 and cutting lines LD4-LD6, also called "second set of folding and cutting lines", being similar to the set formed by folding lines LP21-LP23 and cutting lines LD1-LD3, also called “first set of fold and cut lines” (see ).

In this example, the lower part P1 of the panel 30 thus forms four of said openings 50, the middle part P2 forms eight more of said openings 50 and the upper part P3 forms four more of said openings 50.

Furthermore, the lower part P1 of the panel 30 forms a first of the two openings 51 and a first of the two openings 52, while the middle part P2 forms the second opening 51 and the second opening 52 (see ).

In reference to the , panel 60 is shown in this figure as well as a frame of reference defining directions D1, D2 and D3 which are orthogonal to each other.

In the flat configuration of the , said first surface and said second surface of the panel 60 are spaced from one another in direction D3.

The panel 60 has symmetry with respect to an axis A1 parallel to the direction D2.

The panel 60 comprises a central part 61, a rear part 62, a rear locking element 63 and two side tabs 64 and 65.

The tongues 64 and 65 are spaced from each other in the direction D1 which defines a lateral direction.

The central part 61 comprises in this example three parts 66-68.

The part 67, also called "main part", is connected on the one hand to the rear part 62 along a folding line LP61 and, on the other hand, to each of the parts 66 and 68 along a folding line LP62 or LP63, respectively.

Parts 66 and 68, also called "connecting parts", are each connected to a respective one of tabs 64 and 65 along a fold line LP64 or LP65, respectively.

Concerning the locking element 63, this forms a tongue connected to the rear part 62 along a folding line LP66.

In the configuration of the , the folding lines LP61 and LP66 are parallel to the D1 direction, the folding lines LP64 and LP65 are parallel to the D2 direction, while the folding lines LP62 and LP63 are oblique to the D1 and D2 directions.

In reference to the , panel 90 is shown in this figure as well as a frame of reference defining directions D1, D2 and D3 which are orthogonal to each other.

In the flat configuration of the , said first surface and said second surface of the panel 90 are spaced from one another in direction D3.

The panel 90 has symmetry with respect to an axis A2 parallel to the direction D2.

The panel 90 comprises a central part 91, a rear part 92, a rear locking element 93 and two side parts 94 and 95.

The lateral parts 94 and 95 are spaced from each other in the direction D1 which defines a lateral direction.

In this example, the central part 91 comprises three parts 96-98.

Part 97, also called "main part", is connected on the one hand to the rear part 92 along a folding line LP91 and, on the other hand, to each of the parts 96 and 98 along a folding line LP92 or LP93, respectively.

Parts 96 and 98, also called "connecting parts", are each connected to a respective one of lateral parts 94 and 95 along a fold line LP94 or LP95, respectively.

Concerning the locking element 93, this forms a tongue connected to the rear part 92 along a folding line LP96.

Each of the lateral parts 94 and 95 comprises two portions 101 and 102, which form a so-called reinforcing part, and a lateral end 103 forming a tongue.

For each of the lateral parts 94 and 95, the portion 102 is connected on the one hand to the part 101 along a folding line LP97 and, on the other hand, to the part 96 or 98 along the folding line folding LP94 or LP95, respectively.

For each of the lateral parts 94 and 95, the tongue 103 is connected to the portion 101 along a folding line LP98.

In this example, each of the portions 101 and 102 of the panel 90 has a generally rectangular shape elongated in the direction D2.

In the configuration of the , the folding lines LP91 and LP96 are parallel to the direction D1, the folding lines LP94, LP95, LP97 and LP98 are parallel to the direction D2, while the folding lines LP92 and LP93 are oblique to the directions D1 and D2.

Steps will now be presented for bulking and assembling panels such as those which have just been described so as to form structure 2 illustrated on the .

In this example, structure 2 of the is formed using a panel similar to panel 30 of the to constitute the side walls 5 and 6 as well as the rear wall 7 of the structure 2, of two panels similar to the panel 60 of the to constitute the support elements 16 and 18, and two panels similar to panel 90 of the to constitute the support elements 17 and 19.

Concerning the volume of panel 30, from the flat configuration of the , the parts 31 to 38 are moved relative to each other by folding along the folding lines LP1-LP6 and LP8 so that the second surface of the part 31 comes to bear on the second surface of the part 33, the first surface of part 31 comes to rest on the second surface of part 35, the first surface of part 33 comes to rest on the second surface of part 37, and so that parts 37 and 38 form a right angle with the central part 39 (see Figures 2 and 3).

The parts 40 to 47 are positioned symmetrically, by folding along the folding lines LP9 and LP11-LP16, so that the first surface of the parts 40 and 41 is placed opposite the first surface of the parts 38 and 37.

The panel 30 is thus arranged in the configuration of the in which the parts 31 to 38 of the panel 30 form the side wall 5 of the structure 2, the parts 40 to 47 of the panel 30 form the side wall 6 of the structure 2 and the central part 39 of the panel 30 forms the rear wall 7 of structure 2.

In this configuration, the openings 50 of the part 33 are each aligned with a respective one of the openings 50 of the part 37 to form two by two openings which open on the one hand onto the first surface of the part 37 and elsewhere in an internal space of the side wall 5 extending between parts 33 and 35.

In the same way, the openings 50 of the part 45 are each aligned with a respective one of the openings 50 of the part 41 to form two by two openings which open on the one hand onto the first surface of the part 41 and on the other hand in an internal space of the side wall 6 extending between parts 43 and 45.

In the configuration of the , the panel 30 generally has a U-shaped profile and the side walls 5 and 6 each comprise an internal layer and an external layer.

In this example, the internal layer of the wall 5 is formed by the parts 37 and 38 of the panel 30 and the external layer of this wall 5 is formed by the part 35 of the panel 30. Symmetrically, the internal layer of the wall 6 is formed by parts 40 and 41 of panel 30 and the outer layer of this wall 6 is formed by part 43 of panel 30.

For each of the side walls 5 and 6, the internal layer and the external layer are superimposed on each other and spaced from each other by a distance corresponding substantially to twice the thickness of the panel 30, the internal and external layers of the side wall 5 receiving between them the parts 31 and 33 of the panel 30, the internal and external layers of the side wall 6 receiving between them the parts 45 and 47 of the panel 30.

When panel 30 is in the configuration of the , the support elements 16-19 can be assembled to the panel 30 in the manner described below.

Concerning the support element 16, the panel 60 used to form this support element 16 is assembled with the panel 30 by inserting the tongue 65 into the two openings 50 made in the lower part P1 of the parts 33 and 37 of the panel 30 , insertion of the tongue 64 into the two openings 50 made in the lower part P1 of the parts 41 and 45 of the panel 30, and insertion of the tongue 63 into the opening 52 made in the lower part P1 of the panel 30.

In the same way, the panel 60 used to form the support element 18 is assembled with the panel 30 by inserting the tongue 65 into two of the openings 50 made in the middle part P2 of the parts 33 and 37 of the panel 30, insertion of the tongue 64 in two of the openings 50 made in the middle part P2 of the parts 41 and 45 of the panel 30, and insertion of the tongue 63 in the opening 52 made in the middle part P2 of the panel 30, the openings 50 being well understood those located at the same level, vertically, as this opening 52.

In this way, the support elements 16 and 18 are placed in the position illustrated on the , called "receiving position", in which the tongues 64 and 65 each cooperate with a respective one of the side walls 5 and 6 and in which the central part 61 of each of the support elements 16 and 18 extends in a plane substantially perpendicular to the walls 5-7 of structure 2.

Concerning the support element 17, the panel 90 used to form this support element 17 is assembled with the panel 30 by inserting the tongue 103 of the side part 95 into the two other openings 50 made in the middle part P2 of the parts 33 and 37 of the panel 30, insertion of the tongue 103 of the lateral part 94 into the two openings 50 made in the middle part P2 of the parts 41 and 45 of the panel 30, and insertion of the tongue 93 into the opening 51 made in the middle part P2 of panel 30.

There shows the support element 17 in a first intermediate mounting position in which the tongues 103 are inserted in their openings 50, in which the tongue 93 is not inserted in its opening 51 and in which the portions 101 and 102 of each lateral parts 94 and 95 are oriented in a first direction in the vertical direction, so that the folding lines LP94 and LP95 of the support element 17 extend vertically above the folding line LP21 of the panel 30 (see figures 2, 3 and 5).

There furthermore shows the support element 19 in a second intermediate mounting position which is distinguished from the position in which the support element 17 is located in that the portions 101 and 102 of each of the lateral parts 94 and 95 are oriented in a second direction in the vertical direction, so that the folding lines LP94 and LP95 of the support element 19 extend in this case vertically below the folding line LP24 of the panel 30 (see Figures 2 , 3 and 5).

The passage from the first to the second intermediate mounting position is carried out by lowering the central part 91 of the support element 17/19 causing a rotation of the portions 101 and 102 of each of the lateral parts 94 and 95 relative to the central part 91 around the corresponding folding line LP94 or LP95.

In said second intermediate position, the support element 19 is arranged so that the folding line LP98 of each of its lateral parts 94 and 95 extends vertically above the folding line LP24 and that the folding lines LP94 and LP95 connecting these lateral parts 94 and 95 to the central part 91 of the support element 19 extend vertically below the folding line LP24.

In other words, in said second intermediate position, the portions 101 and 102 of each of the lateral parts 94 and 95 of the support element 19 extend so as to vertically cross the folding line LP24 of the panel 30, so that said second surface formed by the portion 101 of each of the lateral parts 94 and 95 of the support element 19 is supported on said first surface formed by the upper part P3 of the part 41, or respectively 37, of the panel 30, and of so that said second surface formed by the portion 102 of each of the lateral parts 94 and 95 of the support element 19 bears on said first surface formed by the middle part P2 of the part 41, or respectively 37, of the panel 30 .

The same applies to the support element 17 which, when it is in said second intermediate position, is arranged so that the folding line LP98 of each of its lateral parts 94 and 95 extends vertically to the above the folding line LP21 and that the folding lines LP94 and LP95 connecting these lateral parts 94 and 95 to the central part 91 of the support element 17 extend vertically below the folding line LP21 of the panel 30.

In other words, in said second intermediate position, the portions 101 and 102 of each of the lateral parts 94 and 95 of the support element 17 extend so as to vertically cross the folding line LP21, so that said second surface formed by the portion 101 of each of the lateral parts 94 and 95 of the support element 17 is supported on said first surface formed by the middle part P2 of the part 41, or respectively 37, of the panel 30, and so that said second surface formed by the portion 102 of each of the lateral parts 94 and 95 of the support element 17 is supported on said first surface formed by the lower part P1 of the part 41, or respectively 37, of the panel 30.

For each of the support elements 17 and 19, from said second intermediate mounting position, the insertion of the tongue 93 into the corresponding opening 51 makes it possible to place these support elements 17 and 19 in the receiving position.

When the support elements 16-19 are in the receiving position, the central part 61/91 and the rear part 63/93 of each of these support elements extends in a plane substantially perpendicular to the walls 5-7 of the structure 2, making it possible to support a respective plate 4 (see ).

In the receiving position, the arrangement of the lateral parts 94 and 95 of the support elements 17 and 19 relative to the folding lines LP21 and LP24 of the panel 30 makes it possible to avoid unwanted folding of the side walls 5 and 6 of the structure 2 and more generally to reinforce the structural strength of the assembly and thus increase the admissible load on the plates 4.

When structure 2 of the is thus assembled with placement of the support elements 16-19 in the receiving position, the aforementioned covering 3 is arranged around the structure 2 in the manner shown schematically on the and locked on the structure 2 using tabs (not shown) inserted in the openings 54 formed by the panel 30 (see Figures 2 and 3).

The plates 4 are then placed on the support elements 16-19 (see Figures 1 and 2).

The different folding and cutting lines produced in the panels 30, 60 and 90 not only allow the structure 2 to be put into volume in the manner described above but also allow, after removal of the plates 4, to fold the structure 2 into three to place it in a transport configuration. There schematically represents structure 2 in an intermediate configuration between this transport configuration and the configuration of the .

The structure of the support elements 17 and 19, in particular their portions 101 and 102 forming reinforcements, makes it possible to maintain these support elements 17 and 19 in the receiving position when the structure 2 is in the configuration of use while opposing to a movement of the side walls 5 and 6 from the position they occupy on the towards a position in which the parts P1, P2 and/P3 are moved relative to each other around the folding lines LP21 and LP24, in particular towards a position in which they are folded over each other such as in the configuration of transportation.

Among other advantages, such a structure 2 can be put into volume for its use from the transport configuration in which it has a reduced footprint.

Of course, the preceding description is not restrictive, the structure 2 may include a number of stages greater or less than four and/or folding and/or cutting lines otherwise organized.

For example, in an embodiment not shown, the structure 2 comprises one or more support elements formed using a panel which is distinguished from the panel 90 of the in that the lateral parts 94 and 95 do not have the folding line LP97. Such a variant can make it possible to further increase the structural reinforcement function provided by these lateral parts 94 and 95 when the structure 2 is in use configuration. In the context of such a variant, the change in configuration of the structure 2 is preferably carried out by placing the support element(s) thus formed in a position in which the tongues 103 are separated from the side walls 5 and 6.

In a variant embodiment, not shown, the structure can be designed to be folded in four, thus defining three horizontal folding lines, and can comprise three support elements similar to the support elements 17 and 19 so as to be able to reinforce the structure at each of these horizontal fold lines.
