Description

La présente invention se rapporte à un présentoir pliable en carton rigide adapté à être déplié pour y présenter des produits de consommation courante notamment.The present invention relates to a foldable display stand made of rigid cardboard adapted to be unfolded in order to present everyday consumer products therein in particular.

En particulier, le présentoir pliable est adapté à la publicité sur le lieu de vente communément dénommée par son abréviation « PLV ».In particular, the foldable display is suitable for point-of-sale advertising commonly referred to by its abbreviation “POS”.

Des présentoirs pliables à plat en carton rigide et adaptés à être dépliés aisément in situ en formant des étagères pour y déposer des produits afin d'en assurer leur promotion, sont bien connus.Flat foldable displays made of rigid cardboard and adapted to be easily unfolded in situ by forming shelves for depositing products therein in order to ensure their promotion, are well known.

On entend usuellement par « carton rigide », ou « carton semi-rigide », le carton ondulé, constitué par une ou plusieurs feuilles de papier cannelé collées sur une ou plusieurs feuilles de papier plan. La combinaison des feuilles de papier cannelé et des feuilles de papier plan assure la rigidité relative du matériau obtenu.The term "rigid cardboard" or "semi-rigid cardboard" usually means corrugated cardboard, consisting of one or more sheets of corrugated paper glued to one or more sheets of flat paper. The combination of fluted paper sheets and flat paper sheets ensures the relative rigidity of the material obtained.

On connaît des présentoirs pliables comportant une paroi arrière présentant deux bords latéraux et deux parois latérales montées respectivement articulées sur lesdits deux bords latéraux. Les deux parois latérales présentent chacune un bord libre opposé au bord latéral correspondant de la paroi arrière. Aussi, les présentoirs comprennent au moins une tablette d'appui présentant un bord postérieur monté articulé sur la paroi arrière et un bord antérieur opposé libre. En outre, la tablette d'appui présente deux bords latéraux opposés reliés respectivement aux deux parois latérales grâces à deux volets angulaires de 45° centrés sur l'axe d'articulation de la tablette sur la paroi arrière. Ainsi, lorsque les deux parois latérales sont portées verticalement en regard l'une de l'autre tandis qu'elles pivotent sur les deux bords latéraux de la paroi arrière, la tablette se porte perpendiculairement à la paroi arrière et son bord libre vient s'étendre entre les bords libres des parois latérales. Les volets angulaires viennent alors en applique contre l'intérieur des parois latérales.Foldable display units are known comprising a rear wall having two side edges and two side walls mounted respectively hinged on said two side edges. The two side walls each have a free edge opposite the corresponding side edge of the rear wall. Also, the displays comprise at least one support shelf having a rear edge hingedly mounted on the rear wall and a free opposite front edge. In addition, the support shelf has two opposite side edges respectively connected to the two side walls by means of two 45° angular flaps centered on the axis of articulation of the shelf on the rear wall. Thus, when the two side walls are brought vertically opposite each other while they pivot on the two side edges of the rear wall, the tablet is carried perpendicular to the rear wall and its free edge comes extend between the free edges of the side walls. The angular flaps are then applied against the inside of the side walls.

En revanche, lorsque les deux parois latérales sont écartées l'une de l'autre pour être étendues dans le plan de la paroi arrière et de chaque côté de celle-ci, la tablette pivote et vient s'appliquer contre la paroi arrière tandis que les volets angulaires se replient contre les parois latérales. De la sorte, le présentoir replié s'étend à plat.On the other hand, when the two side walls are separated from each other to be extended in the plane of the rear wall and on each side of the latter, the tablet pivots and comes to rest against the rear wall while the angular flaps fold up against the side walls. In this way, the folded display lies flat.

Aussi, il est aisé de prévoir une pluralité de tablettes espacées les unes des autres, reliées à la paroi arrière et aux deux parois latérales de la même façon, pour former un présentoir à plusieurs étages. On pourra notamment se référer au document FR 2 975 576 , lequel décrit un tel présentoir, ou se référer au document FR2956959 A1 .Also, it is easy to provide a plurality of shelves spaced from each other, connected to the rear wall and to the two side walls in the same way, to form a multi-storey display. Reference may be made in particular to the document FR 2 975 576 , which describes such a display, or refer to the document FR2956959 A1 .

On observera toutefois que ce type de présentoir est relativement encombrant lorsqu'il est plié, puisque sa surface d'encombrement est égale à la surface d'encombrement de la paroi arrière et des deux parois latérales situées dans le même plan.Note, however, that this type of display is relatively bulky when folded, since its footprint area is equal to the footprint area of the rear wall and the two side walls located in the same plane.

Aussi, un problème qui se pose et que vise à résoudre la présente invention est de fournir un présentoir pliable aisément dépliable mais plus compact.Also, a problem which arises and which the present invention aims to solve is to provide an easily unfoldable but more compact foldable display stand.

Dans ce but, il est proposé, selon un premier objet, un présentoir pliable en carton rigide comprenant : une paroi arrière présentant deux bords latéraux, et deux parois latérales montées respectivement articulées sur lesdits deux bords latéraux et présentant chacune un bord libre opposé auxdits bords latéraux, lesdites deux parois latérales étant adaptées à être portées en regard l'une de l'autre ; au moins un élément d'appui comportant d'une part un bord postérieur monté articulé sur ladite paroi arrière et un bord antérieur opposé s'étendant entre les bords libres desdites deux parois latérales en regard, et d'autre part une partie intermédiaire s'étendant dudit bord postérieur audit bord antérieur pour pouvoir former une tablette de réception. En outre, ledit bord antérieur est articulé sur lesdits bords libres, tandis que ladite partie intermédiaire est montée articulée sur ledit bord antérieur ; et lesdites deux parois latérales sont adaptées à être pliées respectivement en deux l'une vers l'autre selon une ligne de pliage médiane parallèle au bord latéral de ladite paroi arrière, tandis que ladite partie intermédiaire se plie en deux selon une ligne de pliage transverse sensiblement perpendiculaire aux lignes de pliage médianes pour porter ladite partie intermédiaire et lesdites deux parois latérales respectivement pliées en deux contre ladite paroi arrière.For this purpose, it is proposed, according to a first object, a foldable display stand made of rigid cardboard comprising: a rear wall having two side edges, and two side walls mounted respectively hinged on said two side edges and each having a free edge opposite said edges side, said two side walls being adapted to be brought opposite one another; at least one support element comprising on the one hand a rear edge mounted articulated on said rear wall and an opposite front edge extending between the free edges of said two facing side walls, and on the other hand an intermediate part extending from said rear edge to said front edge to be able to form a receiving shelf. In addition, said front edge is articulated on said free edges, while said intermediate part is mounted articulated on said front edge; and said two side walls are adapted to be folded respectively in half towards each other along a median fold line parallel to the side edge of said rear wall, while said intermediate part folds in half along a transverse fold line substantially perpendicular to the median folding lines to carry said intermediate part and said two side walls respectively folded in half against said rear wall.

Ainsi, une caractéristique de l'invention réside dans le pliage des parois latérales en deux l'une vers l'autre et vers l'intérieur du présentoir pour pouvoir les appliquer pliées à plat contre la paroi arrière tout comme la partie intermédiaire. De la sorte, le présentoir est replié dans le seul périmètre de la paroi arrière sur plusieurs épaisseurs mais de manière plus compacte par rapport au présentoir réalisé selon l'art antérieur.Thus, a characteristic of the invention resides in the folding of the side walls in two towards each other and towards the inside of the display unit in order to be able to apply them folded flat against the rear wall just like the intermediate part. In this way, the display stand is folded in the sole perimeter of the rear wall over several thicknesses but in a more compact manner compared to the display stand produced according to the prior art.

En outre, ladite paroi arrière présente au moins une fente d'ancrage, tandis que ledit bord postérieur présente au moins une languette d'ancrage adaptée à venir en prise à travers ladite au moins une fente d'ancrage. De la sorte, le bord postérieur est non seulement solidaire de la paroi arrière, mais au surplus, le mode de liaison permet d'articuler l'élément d'appui. Avantageusement, la paroi arrière présente deux fentes d'ancrage espacées l'une de l'autre, et le bord postérieur présente lui, deux languettes d'ancrage adaptées à venir en prise à travers lesdites deux fentes d'ancrage.Further, said back wall has at least one anchor slot, while said rear edge has at least one anchor tab adapted to engage through said at least one anchor slot. In this way, the rear edge is not only integral with the rear wall, but in addition, the mode of connection makes it possible to articulate the support element. Advantageously, the rear wall has two anchoring slots spaced apart from each other, and the rear edge has two anchoring tabs adapted to come into engagement through said two anchoring slots.

En outre, ladite partie intermédiaire forme deux trapèzes isocèles reliés ensemble par leur petit côté. De la sorte, les grands côtés des deux trapèzes se prolongent respectivement par le bord postérieur et le bord antérieur opposé. Autrement dit, les grands côtés des trapèzes s'étendent sur une distance sensiblement égale à la distance qui sépare les deux parois latérales en regard. Partant, grâce a cette conformation, la partie intermédiaire présente deux échancrures latérales dos à dos, et comme on l'expliquera plus en détail ci-après, lorsque les deux parois latérales se plient en deux l'une vers l'autre, elles viennent s'étendre dans les échancrures et elles ne sont pas empêchées par la partie intermédiaire qui se plie également. Préférentiellement, ladite ligne de pliage transverse s'étend selon ledit petit côté desdits trapèzes isocèles.Furthermore, said intermediate part forms two isosceles trapeziums connected together by their short side. In this way, the long sides of the two trapezoids are extended respectively by the posterior edge and the opposite anterior edge. In other words, the long sides of the trapeziums extend over a distance substantially equal to the distance which separates the two opposite side walls. Therefore, thanks to this conformation, the intermediate part has two side indentations back to back, and as will be explained in more detail below, when the two side walls bend in half towards each other, they come extend into the indentations and they are not prevented by the intermediate part which also bends. Preferably, said transverse fold line extends along said short side of said isosceles trapezoids.

Préférentiellement, ledit bord antérieur est surmonté d'un rebord. De la sorte, et comme on l'expliquera ci-après, le risque que les produits déposés sur la tablette de réception en tombent, sont négligeables.Preferably, said front edge is surmounted by a rim. In this way, and as will be explained below, the risk of the products deposited on the receiving shelf falling therefrom is negligible.

En outre, et selon un mode de réalisation avantageux, le présentoir pliable comprend en outre une plaque d'appui en carton rigide, par exemple en carton alvéolaire, adaptée à venir en applique sur ladite partie intermédiaire. De la sorte, la tablette de réception présente une surface continue supportée par l'élément d'appui.In addition, and according to an advantageous embodiment, the foldable display further comprises a support plate made of rigid cardboard, for example made of honeycomb cardboard, adapted to be applied to said intermediate part. In this way, the receiving tablet has a continuous surface supported by the support element.

Selon un mode de mise en oeuvre de l'invention particulièrement avantageux, le présentoir pliable comprend en outre un autre élément d'appui comportant d'une part un autre bord postérieur monté articulé sur ladite paroi arrière à une distance dudit un bord postérieur et un autre bord antérieur opposé articulé sur lesdits bords libres à ladite distance dudit un bord antérieur, et d'autre part une autre partie intermédiaire s'étendant dudit autre bord postérieur audit autre bord antérieur.According to a particularly advantageous embodiment of the invention, the foldable display further comprises another support element comprising on the one hand another rear edge mounted articulated on said rear wall at a distance from said one rear edge and a another opposite front edge articulated on said free edges at said distance from said one front edge, and on the other hand another intermediate part extending from said other rear edge to said other front edge.

Autrement dit, le présentoir comprend une paroi arrière présentant deux bords latéraux, et deux parois latérales montées respectivement articulées sur lesdits deux bords latéraux et présentant chacune un bord libre opposé auxdits bords latéraux, lesdites deux parois latérales étant adaptées à être portées en regard l'une de l'autre. Et, il comprend également au moins deux éléments d'appui comportant chacun, d'une part un bord postérieur et un bord antérieur opposé, et d'autre part une partie intermédiaire s'étendant dudit bord postérieur audit bord antérieur pour pouvoir former une tablette de réception ; lesdites au moins deux éléments d'appui sont montés articulés sur ladite paroi arrière à une distance déterminée l'un de l'autre et ils s'étendent entre les bords libres desdites deux parois latérales en regard. En outre, les bords antérieurs sont respectivement articulés sur lesdits bords libres espacés de ladite distance déterminée, tandis que les parties intermédiaires sont respectivement montées articulées sur les bords antérieurs ; et lesdites deux parois latérales sont adaptées à être pliées respectivement en deux l'une vers l'autre selon une ligne de pliage médiane parallèle au bord latéral de ladite paroi arrière, tandis que lesdites parties intermédiaires se plient respectivement en deux selon une ligne de pliage transversale sensiblement perpendiculaire aux lignes de pliage médianes pour porter lesdites parties intermédiaires et lesdites deux parois latérales respectivement pliées en deux contre ladite paroi arrière.In other words, the display unit comprises a rear wall having two side edges, and two side walls mounted respectively articulated on said two side edges and each having a free edge opposite said side edges, said two side walls being adapted to be brought opposite the one from the other. And, it also comprises at least two support elements each comprising, on the one hand a rear edge and an opposite front edge, and on the other hand an intermediate part extending from said rear edge to said front edge in order to be able to form a shelf reception ; said at least two support elements are mounted articulated on said rear wall at a determined distance from one another and they extend between the free edges of said two facing side walls. In addition, the front edges are respectively hinged on said free edges spaced apart by said determined distance, while the intermediate parts are respectively mounted hinged on the front edges; and said two side walls are adapted to be folded respectively in half towards each other along a middle fold line parallel to the side edge of said rear wall, while said intermediate parts fold respectively in half along a fold line transverse substantially perpendicular to the median fold lines to carry said intermediate parts and said two side walls respectively folded in half against said rear wall.

Partant, le présentoir pliable présente au moins deux étages superposés lorsqu'il est maintenu verticalement en appui sur le sol par exemple. On comprend aisément que le présentoir pliable selon l'invention, peut comprendre une pluralité d'étages superposés en prévoyant une paroi arrière et des parois latérales suffisamment longues et un nombre correspondant d'éléments d'appui.Therefore, the foldable display has at least two superimposed floors when it is held vertically resting on the ground, for example. It is easily understood that the foldable display unit according to the invention may comprise a plurality of superimposed levels by providing a rear wall and sufficiently long side walls and a corresponding number of support elements.

Selon un mode de réalisation particulièrement avantageux, ladite paroi arrière présente une ligne de pliage transversale perpendiculaire auxdits deux bords latéraux, tandis que chacune desdites deux parois latérales présente une ligne de découpe transversale s'étendant dans le prolongement de ladite ligne de pliage transversale en formant deux demi-parois.According to a particularly advantageous embodiment, said rear wall has a transverse folding line perpendicular to said two side edges, while each of said two side walls has a transverse cutting line extending in the extension of said transverse folding line by forming two half-walls.

Ainsi, lorsque le présentoir pliable présente une pluralité de tablette de réception, et par conséquent que la paroi arrière et les parois latérales sont longues, il est avantageux de pouvoir les pliées en deux pour rendre le présentoir pliable plus compact. De la sorte, entre deux tablettes de réception, la paroi arrière présente une ligne de pliage transversal et chacune des parois latérales présente une ligne de découpe dans le prolongement de la ligne de pliage transversal. De la sorte, la paroi arrière peut être pliée en deux demi-parois arrière en applique dos à dos, tandis que les deux paires de demi-parois latérales peuvent être repliées respectivement contre leur demi-paroi arrière correspondante. De la sorte, malgré la hauteur du présentoir, il peut être replié de manière compacte.Thus, when the foldable display has a plurality of receiving shelves, and consequently the rear wall and the side walls are long, it is advantageous to be able to fold them in half to make the foldable display more compact. In this way, between two reception shelves, the rear wall has a transverse fold line and each of the side walls has a cutting line in the extension of the transverse fold line. In this way, the rear wall can be folded into two rear half-walls applied back to back, while the two pairs of side half-walls can be folded respectively against their corresponding rear half-wall. In this way, despite the height of the display, it can be folded up compactly.

Aussi, avantageusement, chacune desdites deux paires de demi-parois présentent deux bords de contact opposés comportant des languettes de centrage pour pouvoir centrer lesdites deux demi-parois. De la sorte, lorsque le présentoir est déplié, et que les deux demi-parois arrière sont réajustées dans le même plan, les deux bords de contact de chacune des paires de demi-parois latérales viennent s'ajuster parfaitement bord à bord. Ainsi, les parois latérales donnent l'impression d'être continues.Also, advantageously, each of said two pairs of half-walls have two opposite contact edges comprising centering tongues in order to be able to center said two half-walls. In this way, when the display stand is unfolded, and the two rear half-walls are readjusted in the same plane, the two contact edges of each of the pairs of side half-walls fit perfectly edge to edge. Thus, the side walls give the impression of being continuous.

Selon un autre objet, il est proposé un procédé de réalisation d'un présentoir pliable tel que décrit ci-dessus. Il comprend les étapes suivantes : on fournit un premier flan en carton rigide présentant deux bords de premier flan opposés et deux premières lignes de pliage parallèles auxdits deux bords de premier flan et respectivement à équidistance desdits deux bords de premier flan, ledit premier flan présentant en outre au moins deux ouvertures rectangulaires superposées séparées par une traverse et situées entre lesdites deux premières lignes de pliage, et deux deuxièmes lignes de pliage s'étendant respectivement parallèlement entre lesdits bords de premier flan et lesdites premières lignes de pliage ; on fournit un deuxième flan rectangulaire en carton rigide présentant deux grandes bordures opposées articulées et on relie ensemble lesdits deux bords de premier flan auxdites deux grandes bordures, tandis que ledit premier flan se plie en trois le long desdites deux premières lignes de pliage ; et, on fournit un troisième flan en carton rigide présentant deux bordures d'accrochage opposées et une ligne de pliage transverse à équidistance desdites deux bordures d'accrochage, et on monte l'une desdites bordures d'accrochage articulée sur ladite traverse et l'autre desdites bordures d'accrochage articulée sur ledit deuxième flan rectangulaire en regard.According to another object, there is proposed a method for making a foldable display stand as described above. It comprises the following steps: a first blank of rigid cardboard is provided having two opposite first blank edges and two first fold lines parallel to said two first blank edges and respectively equidistant from said two first blank edges, said first blank having furthermore at least two superimposed rectangular openings separated by a crosspiece and located between said two first fold lines, and two second fold lines extending respectively parallel between said first blank edges and said first fold lines; a second rectangular cardboard blank is provided rigid having two large articulated opposite edges and said two first blank edges are connected together to said two large edges, while said first blank folds in three along said two first fold lines; and, a third rigid cardboard blank is provided having two opposite hanging edges and a transverse fold line equidistant from said two hanging edges, and one of said hinged hanging edges is mounted on said crosspiece and the another of said hooking edges articulated on said second facing rectangular blank.

La [Fig. 1] montre un premier flan 10 réalisé dans une plaque de carton ondulé à double face. Autrement dit, le flan 10 est réalisé dans un carton comprenant un papier cannelé compris entre deux feuilles de papier plan collées de chaque côté. Une telle plaque de carton ondulé est dite « rigide » ou bien « semi-rigide », car elle peut être pliée manuellement sous contrainte.There [ Fig. 1 ] shows a first blank 10 made from a double-sided corrugated cardboard plate. In other words, the blank 10 is made from a cardboard box comprising fluted paper between two sheets of flat paper glued on each side. Such a corrugated cardboard plate is called "rigid" or else "semi-rigid", because it can be bent manually under stress.

Le flan 10 présente une hauteur H, voisine de 1,90 m et une largeur L sensiblement égale à 1,33 m. Ces dimensions sont bien entendu données à titre indicatif dans l'exemple de l'invention que l'on va décrire ci-après. En outre, les lignes portées en trait interrompu sur le flan 10 sont des rainures formant des lignes de pliage, tandis que les lignes en trait plein constituent des découpes.The blank 10 has a height H close to 1.90 m and a width L substantially equal to 1.33 m. These dimensions are of course given to by way of indication in the example of the invention which will be described below. In addition, the lines shown in broken lines on the blank 10 are grooves forming fold lines, while the lines in solid lines constitute cutouts.

Ainsi, le premier flan 10 présente deux premiers bords opposés 12, 14, selon la hauteur H, et espacés l'un de l'autre de ladite largeur L. Aussi, il présente deux premières lignes de pliage 16, 18 parallèles aux deux premiers bords opposés 12, 14 et respectivement à équidistance de ceux-ci. Ces lignes de pliage 16, 18 s'étendent sur toute la hauteur du premier flan 10, à une distance des premiers bords opposés 12, 14, comprise avantageusement entre un quart et un tiers de la largeur L, par exemple 0,28 fois la largeur. En outre, le premier flan 10 présente deux deuxièmes lignes de pliage 17, 19 respectivement situées sensiblement à équidistance des premiers bords opposés 12, 14 et des premières lignes de pliage 16, 18. En conséquence, ces deux deuxièmes lignes de pliage 17, 19 sont aussi dénommées lignes de pliage médianes.Thus, the first blank 10 has two first opposite edges 12, 14, along the height H, and spaced from each other by said width L. Also, it has two first fold lines 16, 18 parallel to the first two opposite edges 12, 14 and respectively equidistant from them. These fold lines 16, 18 extend over the entire height of the first blank 10, at a distance from the first opposite edges 12, 14, advantageously comprised between a quarter and a third of the width L, for example 0.28 times the width. In addition, the first blank 10 has two second fold lines 17, 19 respectively located substantially equidistant from the first opposite edges 12, 14 and the first fold lines 16, 18. Consequently, these two second fold lines 17, 19 are also called center bend lines.

Aussi, le premier flan 10 présente cinq ouvertures rectangulaires transversales, deux inférieures 20, 22, une centrale 24, et deux supérieures 26, 28. Elles sont régulièrement espacées les unes des autres de l'extrémité inférieure 30 du flan 10 jusqu'à l'extrémité supérieure 32. Ces ouvertures rectangulaires transversales 20, 22, 24, 26, 28 sont réalisées en retirant une pièce centrale 34 située à équidistance des deux premières lignes de pliage 16, 18, et présentant les contours d'un rectangle supérieur accolé, à un trapèze isocèle inférieur par son petit côté. De la sorte, on vient former deux volets latéraux 36, 38 respectivement articulés le long des deux premières lignes de pliage 16, 18 et une bordure inférieure 40 articulée sur une traverse 42 grâce à une première ligne de pliage transversale 44.Also, the first blank 10 has five transverse rectangular openings, two lower 20, 22, a central 24, and two upper 26, 28. They are regularly spaced from each other from the lower end 30 of the blank 10 to the upper end 32. These transverse rectangular openings 20, 22, 24, 26, 28 are made by removing a central piece 34 located equidistant from the first two fold lines 16, 18, and having the contours of an adjoining upper rectangle, to an inferior isosceles trapezoid by its short side. In this way, two side flaps 36, 38 are formed respectively articulated along the first two folding lines 16, 18 and a lower edge 40 articulated on a crosspiece 42 thanks to a first transverse folding line 44.

Selon une variante de réalisation de l'invention, non représentée, ladite pièce centrale 34 n'est pas entièrement retirée de manière à pouvoir ménager deux languettes d'accrochage en regard prolongeant respectivement les deux volets latéraux et se rejoignant au centre. On expliquera plus en détail dans la suite de la description l'avantage d'une telle variante de réalisation.According to a variant embodiment of the invention, not shown, said central part 34 is not entirely removed so as to be able to provide two facing tabs for attachment respectively extending the two side flaps and meeting in the center. The advantage of such a variant embodiment will be explained in greater detail later in the description.

De plus, selon une autre variante de réalisation, non représentée, il est pratiqué dans la bordure inférieure 40, deux fentes contiguës dans le prolongement l'une de l'autre, et symétriques l'une de l'autre par rapport à une droite située à équidistance des deux premières lignes de pliage 16, 18.In addition, according to another variant embodiment, not shown, there are made in the lower edge 40, two contiguous slots in the extension of one another, and symmetrical to one another with respect to a straight located equidistant from the first two fold lines 16, 18.

En outre, et selon encore une autre variante de réalisation, non représentée, les deux premiers bords opposés 12, 14 comprennent une pluralité d'onglets de verrouillage présentant chacun deux languettes de verrouillage.In addition, and according to yet another alternative embodiment, not shown, the first two opposite edges 12, 14 comprise a plurality of locking tabs each having two locking tongues.

On observera que les deux premières lignes de pliage 16, 18 sont doublées de manière à ce que les deux volets latéraux 36, 38 puissent être rabattus à 180° en offrant un bord carré et deux arêtes franches.It will be observed that the first two fold lines 16, 18 are doubled so that the two side flaps 36, 38 can be folded down 180°, providing a square edge and two sharp edges.

Les cinq ouvertures rectangulaires transversales 20, 22, 24, 26, 28 sont ménagées de manière identique. En revanche, l'ouverture centrale 24 présente en surplus, dans les deux volets opposés 36, 38, deux découpes en décrochement 46, 48 permettant de former deux languettes d'indexation 50, 52, et à l'inverse en correspondance, deux logements d'indexation 54, 56 dont on expliquera la fonction ci-après.The five transverse rectangular openings 20, 22, 24, 26, 28 are formed identically. On the other hand, the central opening 24 has in addition, in the two opposite flaps 36, 38, two recessed cutouts 46, 48 making it possible to form two indexing tongues 50, 52, and conversely in correspondence, two housings indexing 54, 56 whose function will be explained below.

En outre, les deux découpes en décrochement 46, 48 se prolongent de manière continue et transversalement jusqu'aux deux premiers bords opposés 12, 14, selon un segment rectiligne 58 jusqu'aux deuxièmes lignes de pliage 17, 19, puis selon une ligne courbe 60 en forme de vague entre les deuxièmes lignes de pliage 17, 19 et les deux premiers bords opposés 12, 14.In addition, the two recessed cutouts 46, 48 extend continuously and transversely to the first two opposite edges 12, 14, along a rectilinear segment 58 up to the second fold lines 17, 19, then along a curved line 60 in the form of a wave between the second fold lines 17, 19 and the first two opposite edges 12, 14.

On observera que les découpes en décrochement 46, 48 prolongées par le segment rectiligne 58 et la ligne courbe 60, concourrent à diviser le premier flan 10 en deux parties, une première partie supérieure 62 et une première partie inférieure 64.It will be observed that the recessed cutouts 46, 48 extended by the rectilinear segment 58 and the curved line 60, contribute to dividing the first blank 10 into two parts, a first upper part 62 and a first lower part 64.

Toutefois, les deux parties 62, 64 sont maintenues accolées l'une à l'autre pour être associées au deuxième flan 66 que l'on décrira à présent en regard de la [Fig. 2].However, the two parts 62, 64 are kept attached to each other to be associated with the second blank 66 which will now be described with regard to [ Fig. 2 ].

La [Fig. 2] illustre vue de face le deuxième flan 66, lequel est également réalisé en carton ondulé à double face. Il est de forme rectangulaire et il présente une largeur I sensiblement supérieure à la distance qui s'étend entre les deux premières lignes de pliage 16, 18 du premier flan 10. En outre, sa hauteur h est sensiblement inférieure à la hauteur H du premier flan 10. Les deux flans 10, 66 représentés sur les [Fig. 1] et [Fig. 2] sont sensiblement à la même échelle.There [ Fig. 2 ] illustrates the front view of the second blank 66, which is also made of double-sided corrugated cardboard. It is rectangular in shape and it has a width I substantially greater than the distance which extends between the first two fold lines 16, 18 of the first blank 10. In addition, its height h is substantially less than the height H of the first blank 10. The two blanks 10, 66 represented on the [ Fig. 1 ] And [ Fig. 2 ] are substantially on the same scale.

Aussi, le deuxième flan 66 présente deux deuxièmes doubles lignes de pliage opposées 68, 70 s'étendant sur toute la hauteur h du flan 66, en délimitant deux bordures opposées articulées 72, 74 d'un panneau central que l'on dénommera paroi arrière 76 dans la suite de la description.Also, the second blank 66 has two second opposite double fold lines 68, 70 extending over the entire height h of the blank 66, by delimiting two articulated opposite edges 72, 74 of a central panel which will be called the rear wall 76 in the following description.

En outre, la paroi arrière 76 présente une ligne de pliage transversale 78 prolongée dans les deux bordures opposées articulées 72, 74 par deux découpes rectilignes 80, 82.In addition, the rear wall 76 has a transverse fold line 78 extended in the two opposite hinged edges 72, 74 by two rectilinear cutouts 80, 82.

Conformément à ladite une variante de réalisation précitée, les deux bordures opposées articulées 72, 74 sont remplacées par deux pans, non représentés, et également articulés sur la paroi arrière. Ces deux pans présentent chacun une rangée d'orifices alignés suivant la ligne médiane de chacun de ces deux pans. Aussi, ces deux pans présentent chacun une ligne de pliage confondue avec leur ligne médiane.In accordance with said one aforementioned alternative embodiment, the two opposite hinged edges 72, 74 are replaced by two sections, not shown, and also hinged on the rear wall. These two sections each have a row of orifices aligned along the center line of each of these two sections. Also, these two sections each have a fold line coincident with their center line.

Par ailleurs, selon ladite encore une autre variante de réalisation, non représentée, il est pratiqué dans le panneau arrière 76, le long des doubles lignes de pliage opposées 68, 70, une pluralité de lumières de verrouillage espacées les unes des autres.Furthermore, according to said yet another alternative embodiment, not shown, there is formed in the rear panel 76, along the opposite double folding lines 68, 70, a plurality of interlocking slots spaced from each other.

On précisera que les deux deuxièmes doubles lignes de pliage opposées 68, 70 sont écartées l'une de l'autre d'une distance sensiblement égale à celle qui sépare les deux premières lignes de pliage 16, 18 du premier flan 10. Par ailleurs, la ligne de pliage transversal 78 divise le deuxième flan 66 en une deuxième partie supérieure 84 et une deuxième partie inférieure 86 ; et la hauteur de la deuxième partie inférieure 86 est sensiblement égale à la hauteur de la première partie inférieure 64 du premier flan 10.It will be specified that the two opposite second double fold lines 68, 70 are separated from each other by a distance substantially equal to that which separates the first two fold lines 16, 18 of the first blank 10. the transverse fold line 78 divides the second blank 66 into a second upper part 84 and a second lower part 86; and the height of the second lower part 86 is substantially equal to the height of the first lower part 64 of the first blank 10.

De surcroît, la paroi arrière 76 présente cinq paires de fentes d'ancrage, deux paires de fentes d'ancrage 88, 90 ; 92, 94 situées dans la deuxième partie supérieure 84 et trois paires de fentes d'ancrage 96, 98 ; 100, 102 ; 104, 106 situées dans la deuxième partie inférieure 86.Additionally, rear wall 76 has five pairs of anchor slots, two pairs of anchor slots 88, 90; 92, 94 located in the second upper part 84 and three pairs of anchor slots 96, 98; 100, 102; 104, 106 located in the second lower part 86.

Les cinq paires de fentes d'ancrage 88, 90 ; 92, 94; 96, 98 ; 100, 102 ; 104, 106 sont situées sensiblement à équidistance les unes des autres et chacune des paires se situe au niveau d'une traverse 42 du premier flan 10 illustré sur la [Fig. 1].The five pairs of anchor slots 88, 90; 92, 94; 96, 98; 100, 102; 104, 106 are located substantially equidistant from each other and each of the pairs is located at the level of a crosspiece 42 of the first blank 10 illustrated in [ Fig. 1 ].

On observera que les fentes d'ancrage d'une même paire de fentes sont d'une même longueur et qu'elles s'étendent selon une ligne perpendiculaire aux deux deuxièmes doubles lignes de pliage opposées 68, 70 respectivement à une même distance de ses deuxièmes doubles lignes 68, 70.It will be observed that the anchoring slots of the same pair of slots are of the same length and that they extend along a line perpendicular to the two opposite second double folding lines 68, 70 respectively at the same distance from its second double lines 68, 70.

Ainsi, les deux flans 10, 66 tels que représentés respectivement sur les [Fig. 1] et [Fig. 2] sont assemblés l'un avec l'autre par collage. Pour ce faire, le premier flan 10 tel que représenté sur la [Fig. 1] est plié en trois selon les deux premières lignes de pliage 16, 18 de manière à rabattre deux parois latérales opposées 108, 110 vers l'arrière à sensiblement 90° par rapport à une paroi de façade 112. Les deux premiers bords opposés 12, 14 du premier flan 10 sont alors collés contre l'arrière des deux bordures opposées articulées 72, 74 du deuxième flan 66. On obtient de la sorte un ensemble cylindrique fermé à base rectangulaire.Thus, the two blanks 10, 66 as represented respectively on the [ Fig. 1 ] And [ Fig. 2 ] are assembled with each other by gluing. To do this, the first blank 10 as shown in [ Fig. 1 ] is folded in three along the first two fold lines 16, 18 so as to fold two opposite side walls 108, 110 backwards at substantially 90° with respect to a front wall 112. The first two opposite edges 12, 14 of the first blank 10 are then glued against the rear of the two opposite hinged edges 72, 74 of the second blank 66. A closed cylindrical assembly with a rectangular base is thus obtained.

On observera que les deux parois latérales opposées 108, 110, grâce à la découpe du segment rectiligne 58 de la ligne courbe 60, forment deux paires de demi-parois latérales, une paire supérieure 109 de demi-paroi latérale et une paire inférieure 111.It will be observed that the two opposite side walls 108, 110, thanks to the cutting of the rectilinear segment 58 of the curved line 60, form two pairs of side half-walls, an upper pair 109 of half-side walls and a lower pair 111.

Aussi, les deux flans 10, 66 précités, peuvent être assemblés l'un avec l'autre sans adhésif, selon ladite une variante de réalisation et ladite encore une autre variante de réalisation comme suit.Also, the two aforementioned blanks 10, 66 can be assembled together without adhesive, according to said one variant embodiment and said yet another variant embodiment as follows.

Les deux pans opposés sont repliés l'un vers l'autre sensiblement à 90° par rapport à la paroi arrière, tandis que le premier flan est plié en trois selon les deux premières lignes de pliage 16, 18 de manière à rabattre deux parois latérales opposées vers l'arrière à sensiblement 90° contre les deux pans opposés. Et les onglets de verrouillage sont alors engagés à travers les lumières de verrouillage correspondantes afin de solidariser les deux flans ensemble. On obtient de la sorte un ensemble cylindrique fermé à base rectangulaire.The two opposite sides are folded towards each other substantially at 90° relative to the rear wall, while the first side is folded in three along the first two fold lines 16, 18 so as to fold two side walls opposite towards the rear at substantially 90° against the two opposite sides. And the locking tabs are then engaged through the corresponding locking slots in order to secure the two blanks together. In this way, a closed cylindrical assembly with a rectangular base is obtained.

Par ailleurs, on rabat vers l'arrière les deux volets latéraux, tandis qu'on engage les languettes d'accrochage respectivement à travers les orifices alignés desdites rangés d'orifices. De la sorte, les volets latéraux sont solidaires des deux pans opposés.In addition, the two side flaps are folded backwards, while the hooking tabs are engaged respectively through the holes aligned with said rows of orifices. In this way, the side flaps are integral with the two opposite sides.

On se référera maintenant à la [Fig. 3] illustrant un troisième flan 114 adapté à être installé en cinq exemplaires dans l'assemblage précité pour former cinq éléments d'appui.We will now refer to the [ Fig. 3 ] illustrating a third blank 114 adapted to be installed in five copies in the aforementioned assembly to form five support elements.

Ainsi, ce troisième flan 114 présente deux bordures d'accrochage opposées, une bordure antérieure 116 et une bordure postérieure 118 sensiblement parallèles l'une à l'autre et situées à une distance, l'une de l'autre, sensiblement égale à la largeur des deux parois latérales opposées 108, 110 illustrées sur la [Fig. 1]. De plus, les bordures d'accrochage opposées 116, 118 présentent une largeur sensiblement égale à la largeur de la paroi arrière 76 représentée sur la [Fig. 2].Thus, this third blank 114 has two opposite attachment edges, a front edge 116 and a rear edge 118 substantially parallel to each other and located at a distance, one from the other, substantially equal to the width of the two opposite side walls 108, 110 illustrated in [ Fig. 1 ]. In addition, the opposite hooking edges 116, 118 have a width substantially equal to the width of the rear wall 76 shown in [ Fig. 2 ].

En outre, le troisième flan 114 présente deux échancrures opposées 120, 122 dos à dos, et ménagées de l'une desdites bordures d'accrochage 116, à l'autre 118. Aussi, il présente une double ligne de pliage transverse 124 ménagée sensiblement à équidistance desdites bordures d'accrochage 116, 118. Autrement dit, la double ligne de pliage transverse 124 s'étend dans la zone d'étranglement maximale du troisième flan 114.In addition, the third blank 114 has two opposite notches 120, 122 back to back, and provided from one of said fastening edges 116 to the other 118. Also, it has a double transverse fold line 124 provided substantially equidistant from said hooking edges 116, 118. In other words, the double transverse fold line 124 extends in the maximum constriction zone of the third blank 114.

La bordure d'accrochage antérieure 116 est articulée grâce à une ligne de pliage antérieure 126. À l'opposé, la bordure postérieure 118 présente deux onglets 128, 130 espacés l'un de l'autre. Chacun des onglets 128, 130 présente deux languettes latérales 132, 134 pliables.The front hooking edge 116 is hinged by means of a front fold line 126. In contrast, the rear edge 118 has two tabs 128, 130 spaced apart from each other. Each of the tabs 128, 130 has two side tabs 132, 134 bendable.

Les onglets 128, 130 et les deux languettes latérales 132, 134 pliables forment respectivement deux languettes d'ancrage.The tabs 128, 130 and the two foldable side tabs 132, 134 respectively form two anchoring tabs.

On observera que la largeur des onglets 128, 130 est sensiblement inférieure à celle des fentes d'ancrage des cinq paires de fentes d'ancrage 88, 90 ; 92, 94; 96, 98 ; 100, 102 ; 104, 106. Au surplus, les centres des deux onglets 128, 130 sont situés à une distance égale à ceux des fentes d'ancrage.It will be observed that the width of the tabs 128, 130 is substantially less than that of the anchoring slots of the five pairs of anchoring slots 88, 90; 92, 94; 96, 98; 100, 102; 104, 106. Moreover, the centers of the two tabs 128, 130 are located at a distance equal to those of the anchoring slots.

Par ailleurs, selon ladite autre variante de réalisation, la bordure d'accrochage antérieure 116 est remplacée par deux autres onglets d'accrochage, non représentés et sensiblement opposés aux deux onglets 128, 130.Furthermore, according to said other variant embodiment, the front attachment edge 116 is replaced by two other attachment tabs, not shown and substantially opposite the two tabs 128, 130.

Avant de décrire l'assemblage du troisième flan 114 avec l'ensemble cylindrique précité formé par les deux autres flans 10, 66, on se référera à la [Fig. 1] pour décrire un mode de réalisation particulièrement avantageux. En effet, à des fins de rigidification, des panneaux de renfort non représentés sont collés sur l'arrière du premier flan 10, dans les zones situées entre les premières lignes de pliage 16, 18 et les deuxièmes lignes de pliage 17, 19. Autrement dit, quatre panneaux de renfort sont collés dans ces zones. Deux panneaux de renfort inférieurs sont collés dans les zones de la première partie inférieure 64, de l'extrémité inférieure 30 jusqu'au segment rectiligne de découpe 58. Et deux panneaux de renfort supérieurs sont collés dans les zones de la première partie inférieure, depuis le segment rectiligne de découpe 58 jusqu'au dessus de la dernière ouverture rectangulaire transversale 28. Aussi, les deux volets latéraux 36, 38 sont repliés et collés contre les panneaux de renfort en libérant les ouvertures rectangulaires transversales 20, 22, 24, 26, 28. Celles-ci définissent alors deux bords libres opposés des deux parois latérales opposées 108, 110.Before describing the assembly of the third blank 114 with the aforementioned cylindrical assembly formed by the two other blanks 10, 66, reference will be made to [ Fig. 1 ] to describe a particularly advantageous embodiment. Indeed, for stiffening purposes, reinforcement panels, not shown, are glued to the rear of the first blank 10, in the areas located between the first fold lines 16, 18 and the second fold lines 17, 19. Otherwise said, four reinforcement panels are glued in these areas. Two lower reinforcement panels are glued in the areas of the first lower part 64, from the lower end 30 to the straight cut segment 58. And two upper reinforcement panels are glued in the zones of the first lower part, from the rectilinear cut segment 58 to above the last transverse rectangular opening 28. Also, the two side flaps 36, 38 are folded and glued against the reinforcement panels by releasing the transverse rectangular openings 20, 22, 24, 26, 28. These then define two opposite free edges of the two opposite side walls 108, 110.

Ensuite, cinq exemplaires du troisième flan 114 peuvent être installés à l'intérieur de l'ensemble cylindrique précité.Then, five copies of the third blank 114 can be installed inside the aforementioned cylindrical assembly.

On décrira ce mode d'installation en regard des [Fig. 1], [Fig. 2] et [Fig. 3], et en particulier à hauteur de la dernière ouverture rectangulaire transversale 28.This mode of installation will be described with regard to [ Fig. 1 ], [ Fig. 2] and [Fig. 3 ], and in particular at the height of the last transverse rectangular opening 28.

Ainsi, la bordure d'accrochage antérieure 116 du troisième flan 114 est prise en sandwich entre l'arrière de la traverse 42 et la bordure inférieure 40 repliée à 180° vers l'intérieur de l'ensemble cylindrique. La bordure d'accrochage 116 est collée entre la traverse 42 et la bordure inférieure 40 repliée.Thus, the front hooking edge 116 of the third blank 114 is sandwiched between the rear of the crosspiece 42 and the lower edge 40 folded at 180° towards the inside of the cylindrical assembly. The hooking edge 116 is glued between the crosspiece 42 and the lower edge 40 folded.

À l'opposé, la bordure d'accrochage postérieure 118 est montée articulée sur le deuxième flan rectangulaire en regard 66, et plus précisément sur la paroi arrière 76 en engageant les deux onglets 130, 128 à travers les fentes d'ancrage 88, 90 de la paire supérieure des deux paires de fentes d'ancrage 88, 90 ; 92, 94 de la deuxième partie supérieure 84 du deuxième flan 66. Pour engager les onglets 130, 128 dans les deux fentes d'ancrage 88, 90, on procède tout d'abord au repli des languettes latérales 132, 134 vers le centre des onglets 130, 128. Puis ensuite, lorsque les onglets 130, 128 viennent s'étendre en saillie à l'arrière de la paroi arrière 76, on déplie des languettes latérales 132, 134 en regard de la face arrière de la paroi arrière 76, en dehors des fentes d'ancrage 88, 90 de manière à interdire le retrait des onglets 130, 128. De la sorte, la bordure d'accrochage postérieure 118 est en prise dans la paroi arrière 76 en regard de la traverse 42. Et au surplus, elle est articulée sur cette paroi arrière 76 selon une ligne de pliage définie par les fentes d'ancrage 88, 90.On the other hand, the rear attachment edge 118 is mounted articulated on the second facing rectangular blank 66, and more precisely on the rear wall 76 by engaging the two tabs 130, 128 through the anchoring slots 88, 90 the upper pair of the two pairs of anchor slots 88, 90; 92, 94 of the second upper part 84 of the second blank 66. To engage the tabs 130, 128 in the two anchoring slots 88, 90, the first step is to fold the side tabs 132, 134 upwards. center of the tabs 130, 128. Then then, when the tabs 130, 128 come to extend projecting at the rear of the rear wall 76, side tabs 132, 134 are unfolded opposite the rear face of the rear wall 76, outside the anchoring slots 88, 90 so as to prevent the removal of the tabs 130, 128. In this way, the rear hooking edge 118 is engaged in the rear wall 76 opposite the crosspiece 42. And moreover, it is articulated on this rear wall 76 along a folding line defined by the anchoring slots 88, 90.

Aussi, les quatre autres traverses 42 définies par les quatre autres ouvertures rectangulaires transversales 20, 22, 24, 26 sont de la même façon équipées d'un troisième flan 114, et reliées à la paroi arrière 76 par l'intermédiaire des quatre autres paires de fentes d'ancrage 92, 94 ; 96, 98 ; 100, 102 ; 104, 106.Also, the four other crosspieces 42 defined by the other four transverse rectangular openings 20, 22, 24, 26 are similarly equipped with a third blank 114, and connected to the rear wall 76 via the four other pairs anchor slots 92, 94; 96, 98; 100, 102; 104, 106.

Ainsi, les troisièmes flans 114, permettent de réaliser chacun, un élément d'appui comprenant, un bord antérieur formé de la traverse 42, de la bordure d'accrochage antérieure 116 et du bord inférieur 40 replié contre elle, et à l'opposé un bord postérieur formé grâce à la bordure d'accrochage postérieure 118 engagée dans la paroi arrière 76. Aussi, les troisièmes flans 114 définissent une partie intermédiaire s'étendant du bord postérieur au bord antérieur en formant deux trapèzes isocèles 113, 115 reliés ensemble par leurs petits côtés.Thus, the third blanks 114 each make it possible to produce a support element comprising a front edge formed by the crosspiece 42, the front hooking edge 116 and the lower edge 40 folded against it, and opposite a posterior edge formed thanks to the posterior hooking edge 118 engaged in the rear wall 76. Also, the third blanks 114 define an intermediate part extending from the posterior edge to the anterior edge by forming two isosceles trapeziums 113, 115 connected together by their short sides.

Aussi, on observera que la traverse 42 permet de réaliser au surplus un rebord surmontant le bord antérieur. On retrouvera ci-après sur la [Fig. 6], l'élément d'appui et son bord antérieur surmonté par son rebord.Also, it will be observed that the crosspiece 42 also makes it possible to produce a rim surmounting the front edge. We will find below on the [ Fig. 6 ], the support element and its front edge surmounted by its rim.

Selon ladite autre variante de réalisation précitée, les deux autres onglets d'accrochage de la bordure d'accrochage antérieure du troisième flan sont respectivement engagés à travers les deux fentes contiguës pratiquées dans la bordure inférieure 40. De la sorte, les deux autres onglets d'accrochage viennent en prise dans les deux fentes contiguës et sont pris en sandwich entre l'arrière de la traverse et la bordure inférieure repliée à 180° vers l'intérieur de l'ensemble cylindrique. Il n'est alors ici, nul besoin d'adhésif.According to said other aforementioned alternative embodiment, the two other attachment tabs of the front attachment edge of the third blank are respectively engaged through the two contiguous slots made in the lower edge 40. In this way, the two other tabs of 'hooking come into engagement in the two contiguous slots and are sandwiched between the rear of the crosspiece and the lower edge folded 180 ° inwardly of the cylindrical assembly. It is then here, no need for adhesive.

Ainsi, on observera que ladite variante de réalisation précitée, ladite une autre variante de réalisation et ladite encore une autre variante de réalisation, permettent de réaliser un présentoir pliable sans adhésif. Les éléments sont en effet reliés ensemble par des liaisons mécaniques.Thus, it will be observed that said aforementioned alternative embodiment, said another alternative embodiment and said yet another alternative embodiment, make it possible to create a foldable display without adhesive. The elements are indeed linked together by mechanical links.

En outre, la [Fig. 4] illustre une plaque d'appui 136 rectangulaire en carton. Cette plaque d'appui 136 présente une longueur sensiblement égale à la distance séparant les deux premières lignes de pliage 16, 18 du premier flan 10, et une largeur sensiblement égale à la largeur des deux parois latérales opposées 108, 110 du premier flan 10. La plaque d'appui 136 peut être en carton ondulé, double face par exemple. Elle peut également être réalisée dans un carton plus rigide, par exemple un carton alvéolé.Also, the [ Fig. 4 ] illustrates a rectangular cardboard backing plate 136. This support plate 136 has a length substantially equal to the distance separating the first two fold lines 16, 18 of the first blank 10, and a width substantially equal to the width of the two opposite side walls 108, 110 of the first blank 10. The support plate 136 can be made of corrugated cardboard, double-sided for example. It can also be made in a more rigid cardboard, for example a honeycomb cardboard.

De la sorte, la plaque d'appui 136 est insérée à l'intérieur de l'ensemble cylindrique précité et en applique sur ladite partie intermédiaire définie par le troisième flan 114.In this way, the support plate 136 is inserted inside the aforementioned cylindrical assembly and bears against said intermediate part defined by the third blank 114.

La [Fig. 5] illustre un présentoir pliable 138 ainsi réalisé, dans un état déplié. On retrouve sur cette figure la paroi arrière 76 et sa ligne de pliage transversal 78 ainsi que les deux parois latérales opposées en regard l'une de l'autre 108, 110.There [ Fig. 5 ] illustrates a foldable display 138 thus produced, in an unfolded state. We find in this figure the rear wall 76 and its transverse folding line 78 as well as the two opposite side walls facing each other 108, 110.

On retrouve également les deux premières lignes de pliage 16, 18, délimitant les deux bords libres 107, et les deuxièmes lignes de pliage 17, 19 du premier flan 10 sensiblement parallèles entre elles. Aussi, on aperçoit sur la figure, la découpe du segment rectiligne 58 et de la ligne courbe 60 en forme de vague sur la face externe de la paroi latérale 110. La découpe du segment rectiligne 58 de l'autre paroi latérale 108 est ici cachée. En revanche, apparait à l'intérieur, la découpe en décrochement 46 de cette dernière paroi latérale prolongée par la découpe en ligne courbe 60. L'autre découpe en décrochement 48 est ici masquée. La découpe en décrochement 46, permet de former la languette d'indexation 50, ou languette de centrage, et le logement d'indexation 54 correspondant dans laquelle elle vient s'engager. Ainsi, un tel agencement permet l'ajustement parfaitement centré des deux demi-parois latérales respectivement des deux paires de demi-parois latérales 109, 111. De plus, la découpe en ligne courbe 60 participe également de ce centrage.There are also the two first fold lines 16, 18, delimiting the two free edges 107, and the second fold lines 17, 19 of the first blank 10 substantially parallel to each other. Also, we see in the figure, the cutout of the straight segment 58 and the curved line 60 in the form of a wave on the outer face of the side wall 110. The cutout of the straight segment 58 of the other side wall 108 is here hidden . On the other hand, appears inside, the recessed cutout 46 of this last side wall extended by the curved line cutout 60. The other recessed cutout 48 is hidden here. The recessed cutout 46 makes it possible to form the indexing tongue 50, or centering tongue, and the corresponding indexing housing 54 in which it engages. Thus, such an arrangement allows the perfectly centered adjustment of the two side half-walls respectively of the two pairs of side half-walls 109, 111. In addition, the curved line cutout 60 also contributes to this centering.

En outre, et selon un mode de réalisation particulièrement avantageux, les languettes d'indexation 50, 52 sont munies à l'intérieur d'un adhésif double-face de manière à pouvoir les rendre solidaires des panneaux de renfort inférieurs situés dans les zones de la première partie inférieure. Grâce à ce mode de réalisation, les parties supérieure et inférieure sont maintenues l'une à l'autre. Ainsi, les deux paires de demi-parois latérales 109, 111, apparaissent comme formant deux parois latérales opposées 108, 110 parfaitement continues.In addition, and according to a particularly advantageous embodiment, the indexing tongues 50, 52 are provided inside with a double-sided adhesive so as to be able to make them integral with the reinforcement panels lower located in the areas of the first lower part. Thanks to this embodiment, the upper and lower parts are held together. Thus, the two pairs of side half-walls 109, 111 appear as forming two opposite side walls 108, 110 which are perfectly continuous.

Aussi, et selon un mode de réalisation préféré, les logements d'indexation sont formés en U avec une profondeur plus importante que celle des logements 54, 56 illustrés sur la [Fig. 1], tandis que les languettes d'indexation, en correspondance, sont plus longues. De la sorte, on peut s'affranchir de la mise en oeuvre d'un adhésif car, les languettes d'indexation ainsi allongées, engagées dans les logements d'indexation en U assurent un blocage mécanique des parties supérieures et inférieures.Also, and according to a preferred embodiment, the indexing housings are U-shaped with a greater depth than that of the housings 54, 56 illustrated in [ Fig. 1 ], while the corresponding indexing tabs are longer. In this way, it is possible to dispense with the use of an adhesive because the indexing tabs thus elongated, engaged in the U-shaped indexing housings, provide mechanical locking of the upper and lower parts.

Par ailleurs, on observera que des plaques d'appui 136, du type représenté sur la [Fig. 4], ont été insérées à l'intérieur de l'ensemble cylindrique et mises en applique sur la partie intermédiaire de l'élément d'appui. De la sorte, les produits dont l'on souhaite faire la promotion peuvent être présentés et déposés sur l'élément d'appui. On observera que le rebord préserve ces produits de leur chute occasionnelle.Furthermore, it will be observed that bearing plates 136, of the type shown in [ Fig. 4 ], were inserted inside the cylindrical assembly and applied to the intermediate part of the support element. In this way, the products which it is desired to promote can be presented and placed on the support element. It will be observed that the rim protects these products from their occasional fall.

Un avantage du présentoir pliable 138 conforme à l'invention réside dans son mode de re-pliage qui permet d'obtenir un élément compact malgré ses dimensions lorsqu'il est déplié.An advantage of the foldable display 138 according to the invention resides in its mode of re-folding which makes it possible to obtain a compact element despite its dimensions when it is unfolded.

Ainsi, à partir du présentoir 138 représenté sur la [Fig. 5], on vient retirer tout d'abord les plaques d'appui 136.Thus, from the display 138 shown in [ Fig. 5 ], we first remove the support plates 136.

Ensuite, on vient décoller les languettes d'indexation 50, 52 de manière à pouvoir libérer les demi-parois des deux paires 109, 111. Puis on vient basculer la partie supérieure vers l'arrière autour de la ligne de pliage transversal 78 de la paroi arrière 76. Les deux parties 86, 84 de paroi arrière 76 que divise la ligne de pliage transversale 78 sont alors portées dos à dos.Then, the indexing tabs 50, 52 are unstuck so as to be able to release the half-walls of the two pairs 109, 111. Then the upper part is tilted rearward around the transverse fold line 78 of the rear wall 76. The two parts 86, 84 of the rear wall 76 which the transverse fold line 78 divides are then brought back to back.

Puis, on procède pour chacune des parties supérieures et inférieures, au pliage en deux l'une vers l'autre des demi-parois latérales selon les deuxièmes lignes de pliage 17, 19. Simultanément, les parties intermédiaires se plient selon la double ligne de pliage transverse 124 du troisième flan 114.Then, one proceeds for each of the upper and lower parts, folding in two towards each other of the side half-walls along the second folding lines 17, 19. Simultaneously, the intermediate parts fold along the double line of transverse folding 124 of the third blank 114.

On se référera à présent sur la [Fig. 6] montrant partiellement la partie supérieure du présentoir 138 lorsqu'elle se replie et à des fins de compréhension du mode de pliage. Ainsi, on retrouve les deuxièmes lignes de pliage 17, 19, ou lignes de pliage médianes, qui s'étendent au-delà du présentoir pour une meilleure compréhension. On retrouve également les premières lignes de pliage 16, 18.We will now refer to the [ Fig. 6 ] partially showing the upper part of the display 138 when it folds and for purposes of understanding the mode of folding. Thus, we find the second fold lines 17, 19, or median fold lines, which extend beyond the display for a better understanding. There are also the first fold lines 16, 18.

Aussi, la [Fig. 6] montre deux éléments d'appui 140 à distance l'un de l'autre et comportant deux bords antérieurs 142, surmontés respectivement d'un rebord 144, et deux bords postérieurs opposés 146 articulés sur la paroi arrière 76. Comme indiqué ci-dessus, les bords antérieurs 142 résultent de l'assemblage des traverses 42, de la bordure d'accrochage antérieure ici cachée et du bord inférieur 40 replié contre elle.Also, the [ Fig. 6 ] shows two support elements 140 at a distance from each other and comprising two front edges 142, surmounted respectively by a flange 144, and two opposite rear edges 146 articulated on the rear wall 76. As indicated above , the front edges 142 result from the assembly of the crosspieces 42, the front fastening edge here hidden and the lower edge 40 folded against it.

On retrouve également les parties intermédiaires comprenant respectivement les deux trapèzes isocèles 113, 115, lesquels sont séparés l'un de l'autre par la ligne de pliage transverse 124. Ainsi, lorsque les deux parois latérales opposées 108, 110 se plient en deux l'une vers l'autre selon les deuxièmes lignes de pliage 17, 19, elles se rapprochent l'une de l'autre selon les flèches R, T, tandis que les parties intermédiaires se plient également. Les deux trapèzes isocèles 113, 115 des parties intermédiaires se plient l'un par rapport à l'autre selon la ligne de pliage transverse 124, et respectivement par rapport au rebord 144 et à la paroi arrière 76.
On observera que les deux parois latérales opposées 108, 110 sont autorisés à se plier dans les échancrures 120, 122 des parties intermédiaires.There are also the intermediate parts comprising respectively the two isosceles trapezoids 113, 115, which are separated from each other by the transverse folding line 124. Thus, when the two opposite side walls 108, 110 fold in two l towards each other along the second fold lines 17, 19, they approach each other along the arrows R, T, while the intermediate parts also fold. The two isosceles trapezoids 113, 115 of the intermediate parts fold relative to each other along the transverse fold line 124, and respectively relative to the rim 144 and to the rear wall 76.
It will be observed that the two opposite side walls 108, 110 are allowed to bend into the cutouts 120, 122 of the intermediate parts.

En poursuivant le mouvement de rapprochement des deux parois latérales opposées 108, 110, comme illustré sur la [Fig. 7], elles se plient en deux l'une sur l'autre et viennent s'appliquer à plat contre la paroi arrière 76, tout comme les parties intermédiaires constituées des deux trapèzes isocèles 113, 115. On obtient ainsi un pliage compact de la partie supérieure du présentoir 138.By continuing the approaching movement of the two opposite side walls 108, 110, as illustrated in [ Fig. 7 ], they fold in two on top of each other and come to rest flat against the rear wall 76, just like the intermediate parts consisting of the two isosceles trapezoids 113, 115. A compact folding of the part is thus obtained. top of display 138.

Aussi, on comprend que la partie inférieure du présentoir 138 est repliée de la même façon au dos de la paroi arrière 76.Also, it is understood that the lower part of the display 138 is folded in the same way on the back of the rear wall 76.

L'exemple ici décrit au regard des [Fig. 1], [Fig. 2] et [Fig. 5], visant à former cinq tablettes de réception l'est à titre illustratif.The example described here with regard to [ Fig. 1 ], [ Fig. 2 ] And [ Fig. 5 ], aiming to form five reception shelves is for illustrative purposes.

Bien entendu, il est possible de prévoir un présentoir pliable selon l'invention présentant moins de tablettes, ou bien plus de tablettes de réception et, pliable en deux parties ou non.Of course, it is possible to provide a foldable display according to the invention having fewer shelves, or even more reception shelves and, foldable in two parts or not.

En outre, il est décrit ci-dessus le pliage compact du présentoir 138. A l'inverse, le dépliage est tout aussi aisé et rapide.In addition, the compact folding of the display stand 138 is described above. Conversely, unfolding is just as easy and quick.
