La présente invention concerne un siège démontable, tel que fauteuil ou canapé, réalisé uniquement à partir de flans en carton ou en carton ondulé, convenablement découpés et rainés .The present invention relates to a removable seat, such as an armchair or sofa, produced solely from cardboard or corrugated cardboard blanks, suitably cut and creased.
Le siège selon l'invention est caractérisé en ce qu'il comprend :The seat according to the invention is characterized in that it comprises:
- un flan d'assise en carton ou en carton ondulé, de forme rectangulaire et pourvu à ses bords longitudinaux de languettes, ledit flan d'assise étant plié selon des lignes de pliage transversales et parallèles qui définissent une paroi d'assise, une paroi de dossier, une paroi d'épaisseur de dossier et une paroi de retour de dossier,- a seat blank of cardboard or corrugated cardboard, rectangular in shape and provided at its longitudinal edges with tongues, said seat blank being folded along transverse and parallel fold lines which define a seat wall, a wall backrest, a backrest thickness wall and a backrest wall,
- deux flans d'accoudoirs identiques en carton ou en carton ondulé, chacun d'eux étant replié et fermé pour former une boîte parallélépipédique plate, les deux boîtes ainsi formées étant disposées dans deux plans parallèles pour constituer les accoudoirs du siège, les deux grandes parois latérales des accoudoirs qui se font face étant pourvues de fentes pour y insérer les languettes du flan d' assise,- two identical armrest blanks of cardboard or corrugated cardboard, each of them being folded and closed to form a flat rectangular box, the two boxes thus formed being arranged in two parallel planes to constitute the armrests of the seat, the two large side walls of the armrests which face each other being provided with slots for inserting therein the tabs of the seat blank,
- et une pluralité de barres de renfort en carton, dont les extrémités pénètrent dans des trous prévus sur les parois intérieures des accoudoirs , de manière à relier entre eux ces derniers, afin d'assurer leur parallélisme et de garantir la résistance de la paroi d'assise et de la paroi du dossier contre la pression du poids du corps.- And a plurality of cardboard reinforcing bars, the ends of which penetrate into holes provided on the interior walls of the armrests, so as to connect the latter, in order to ensure their parallelism and to guarantee the resistance of the wall d seat and back wall against the pressure of the body weight.
Les éléments constitutifs du siège peuvent être vendus à plat ou repliés pour obtenir un volume compact facile à transporter. Bien qu'ils soient assemblés uniquement par pliage et sans colle, ils forment un siège rigide et indéformable dans les conditions normales d'utilisation.The components of the seat can be sold flat or folded to obtain a compact volume that is easy to transport. Although they are assembled only by folding and without glue, they form a rigid and non-deformable seat under normal conditions of use.
Un tel siège peut être facilement monté - par l'utilisateur chez lui. Il est léger puisqu'il ne comporte que des éléments en carton et il peut donc être facilement transporté. Sous sa forme emballée, il n'occupe qu'un très faible volume, ce qui permet de le ranger dans le coffre d'une voiture ou d'un camping-car. Enfin, son faible prix le met à la portée de toutes les bourses. Il peut être emporté sur un lieu de camping. Recouvert d'une housse, il peut même trouver sa place dans un appartement de personnes débutant dans la vie, telles que des étudiants ou des nouveau mariés. L'invention sera décrite à présent à titre d'exemple en regard des dessins annexés, dans lesquels :Such a seat can be easily mounted - by the user at home. It is light since it only contains cardboard elements and can therefore be easily transported. In its wrapped form, it occupies only a very small volume, which allows it to be stored in the trunk a car or a motorhome. Finally, its low price puts it within reach of all budgets. It can be taken to a campsite. Covered with a cover, it can even find its place in an apartment for people starting out in life, such as students or newlyweds. The invention will now be described by way of example with reference to the appended drawings, in which:
La figure 1 est une vue en perspective d'un fauteuil obtenu selon le principe de l'invention ; la figure 2 représente le flan destiné à former l'assise et le dossier du fauteuil ; les figures 3 et 4 représentent respectivement le flan gauche et le flan droit destinés à réaliser les deux accoudoirs ; la figure 5 représente le fauteuil en cours de montage ; et la figure 6 est une vue du fauteuil démonté et mis sous une forme compacte pour le transport ;Figure 1 is a perspective view of an armchair obtained according to the principle of the invention; FIG. 2 represents the blank intended to form the seat and the back of the chair; Figures 3 and 4 show respectively the left blank and the right blank intended to make the two armrests; Figure 5 shows the chair during assembly; and Figure 6 is a view of the chair disassembled and put in a compact form for transport;
Avec référence à la figure 1, le fauteuil 10 comprend, de façon connue en soi, un ensemble dossier 11 et assise 12 compris entre deux accoudoirs 14 et 16.With reference to FIG. 1, the chair 10 comprises, in a manner known per se, a backrest 11 and seat 12 assembly comprised between two armrests 14 and 16.
L'originalité de l'invention réside dans le fait que tous ces éléments sont réalisés uniquement à partir de flans en carton ou en carton ondulé, convenablement plies et assemblés entre eux.The originality of the invention resides in the fact that all of these elements are produced only from cardboard or corrugated cardboard blanks, suitably folded and assembled together.
L'ensemble dossier 11 et assise 12 est réalisé au moyen d'un flan rectangulaire 17 représenté à la figure 2. Sur ce flan sont marquées quatre lignes de pliage transversales 18, 20, 22, 24 qui définissent successivement une paroi de retour de dossier 26, une paroi d'épaisseur de dossier 28, une paroi de dossier 30, une paroi d'assise 32 et une paroi d'épaisseur d'assise 34.The back 11 and seat 12 assembly is produced by means of a rectangular blank 17 shown in FIG. 2. On this blank are marked four transverse fold lines 18, 20, 22, 24 which successively define a back wall for the back 26, a back thickness wall 28, a back wall 30, a seat wall 32 and a seat thickness wall 34.
La paroi de dossier 30 présente sur ses bords longitudinaux deux languettes 36, 38. De même, la paroi d'assise 32 comporte deux languettes 40, 42 sur ses bords longitudinaux. La paroi de retour de dossier 26 et la paroi d'épaisseur de siège 34 sont pourvues chacune de languettes en forme de crochets, respectivement 44, 46 et 48, 50.The back wall 30 has on its longitudinal edges two tongues 36, 38. Likewise, the seat wall 32 has two tongues 40, 42 on its longitudinal edges. The backrest wall 26 and the seat thickness wall 34 are each provided with tongues in the form of hooks, respectively 44, 46 and 48, 50.
Avec référence aux figures 3 et 4, les deux accoudoirs sont réalisés à partir de deux flans rectangulaires 52, 53 en carton ou carton ondulé. Ces flans ont une symétrie spéculaire de sorte qu'il suffira d'en décrire l'un d'eux.With reference to Figures 3 and 4, the two armrests are made from two rectangular blanks 52, 53 of cardboard or corrugated cardboard. These blanks have a specular symmetry so that it will suffice to describe one of them.
Sur le flan 52 par exemple, sont marquées deux lignes de pliage longitudinales 54, 56, et trois lignes de pliage transversales 58, 60, 62, qui permettent de mettre le flan sous forme d'une boîte parallélépipédique plate ayant deux grandes parois parallèles 64, 66, deux petites parois 68, 70 et des volets latéraux 65, 67, 69, 71.On the blank 52, for example, are marked two longitudinal fold lines 54, 56, and three transverse fold lines 58, 60, 62, which allow the blank to be placed in the form of a flat parallelepiped box having two large parallel walls 64 , 66, two small walls 68, 70 and side flaps 65, 67, 69, 71.
La paroi 66 constitue la face intérieure de l'accoudoir, tandis que la paroi 70 constitue la surface d'appui sur laquelle l'utilisateur repose ses coudes. La paroi 68 est destinée à reposer sur le sol. La paroi 68 est pourvue sur son bord longitudinal d'une languette 72 pliable selon une ligne d'articulation 74 sur laquelle sont pratiquées deux fentes 76, 78 en U. La paroi 66 porte sur son bord transversal libre 80 deux pattes de verrouillage 82, 84 pliées en forme de L destinées à s'insérer dans les fentes 76, 78. Chacun des volets latéraux 69, 71 est pourvu à ses extrémités de languettes de fermeture 73, 75, 77, 79.The wall 66 constitutes the inner face of the armrest, while the wall 70 constitutes the bearing surface on which the user rests his elbows. The wall 68 is intended to rest on the ground. The wall 68 is provided on its longitudinal edge with a foldable tongue 72 along a line of articulation 74 on which two slots 76, 78 are made in U. The wall 66 carries on its free transverse edge 80 two locking tabs 82, 84 folded into an L shape intended to be inserted into the slots 76, 78. Each of the side flaps 69, 71 is provided at its ends with closing tabs 73, 75, 77, 79.
Les accoudoirs sont mis en forme uniquement par pliage et sans collage. Pour cela, la fermeture de la caisse est réalisée en imbriquant les volets latéraux 65, 67 dans les intervalles formés entre les volets latéraux 69, 71 et les languettes 73, 75, 77, 79 repliées vers l'intérieur. De même, la fermeture de la caisse à son extrémité inférieure est assurée au moyen de la languette 72 et des pattes 82, 84 qui pénètrent dans les fentes 76, 78, comme cela est représenté sur la figure 5.The armrests are shaped only by folding and without gluing. For this, the closure of the box is achieved by nesting the side flaps 65, 67 in the gaps formed between the side flaps 69, 71 and the tabs 73, 75, 77, 79 folded inward. Likewise, the closing of the box at its lower end is ensured by means of the tongue 72 and the tabs 82, 84 which penetrate into the slots 76, 78, as shown in FIG. 5.
Chacun des accoudoirs présente sur sa paroi intérieure 66, une pluralité de fentes destinées à recevoir les languettes de l'ensemble dossier 11 et assise 12. Ces fentes sont convenablement disposées pour donner sa forme au flan d'assise 17, lequel est préalablement replié sous une forme provisoire montrée sur la figure 5. Plus particulièrement, les parois intérieures 66 des deux accoudoirs présentent des fentes 86 légèrement inclinées vers l'arrière et vers le bas par rapport à l'horizontale et destinées à recevoir les languettes 40, 42 de l'assise. Cette inclinaison détermine la position horizontale légèrement inclinée de la paroi d'assise 32. Les" parois 66 présentent également des fentes 88 sensiblement verticales inclinées vers le bas et vers l'avant de manière à déterminer la position pratiquement verticale de la paroi de dossier 30. Dans les fentes 88 pénètrent les languettesEach of the armrests has on its inner wall 66, a plurality of slots intended to receive the tabs of the backrest 11 and seat assembly 12. These slots are suitably arranged to give its shape to the seat blank 17, which is previously folded under a provisional form shown in Figure 5. More particularly, the interior walls 66 of the two armrests have slots 86 slightly inclined rearward and downward relative to the horizontal and intended to receive the tongues 40, 42 of the seat. This inclination determines the slightly inclined horizontal position of the seat wall 32. The " walls 66 also have substantially vertical slots 88 inclined downwards and forwards so as to determine the practically vertical position of the back wall 30 In the slots 88 penetrate the tabs
36, 38 de la paroi de dossier 30. Sur les parois 66 sont également prévues des fentes 90 parallèles aux fentes 88 et dans lesquelles s'insèrent et s'accrochent les languettes en forme de crochets 44, 46 formées sur la paroi de retour 26, et deux fentes pratiquement verticales 92 dans lesquelles s'insèrent les languettes en forme de crochets 48, 50, qui sont formées sur la paroi d'épaisseur d'assise 34.36, 38 of the back wall 30. On the walls 66 are also provided slots 90 parallel to the slots 88 and into which the hook-shaped tongues 44, 46 are inserted and hooked formed on the return wall 26 , and two practically vertical slots 92 into which the hook-shaped tongues 48, 50 are inserted, which are formed on the seat thickness wall 34.
La rigidité du siège est réalisée au moyen de barres de renfort destinées à relier entre eux les accoudoirs en assurant leur parallélisme. Ces barres de renfort sont disposées au contact de paroi d'assise et de dossier dont elles garantissent la résistance contre la pression du poids de corps. Elles sont constituées, de façon connue en soi, par des tubes en carton ou par des poutrelles en carton replié plusieurs fois sur lui-même.The rigidity of the seat is achieved by means of reinforcing bars intended to connect the armrests to one another while ensuring their parallelism. These reinforcement bars are arranged in contact with the seat wall and the backrest of which they guarantee the resistance against the pressure of the body weight. They are constituted, in a manner known per se, by cardboard tubes or by cardboard beams folded several times on itself.
Une première barre de renfort 94 est disposée dans l'angle formé entre la paroi d'assise 32 et la paroi d'épaisseur d'assise 34. Les extrémités de cette barre de renfort pénètrent dans des trous 96 formés sur la paroi intérieure 66 des accoudoirs.A first reinforcement bar 94 is arranged in the angle formed between the seat wall 32 and the seat thickness wall 34. The ends of this reinforcement bar penetrate into holes 96 formed on the inner wall 66 of the armrests.
Une deuxième barre de renfort 98 est disposée sous la paroi d'assise 32 et ses extrémités pénètrent dans des trous 100 prévus sous les fentes 86.A second reinforcing bar 98 is arranged under the seat wall 32 and its ends penetrate into holes 100 provided under the slots 86.
Un mandrin tubulaire en carton 102 est disposé sous l'angle formé par la paroi d'assise 32 et la paroi de dossier 30 et ses extrémités pénètrent dans des trous circulaires 104 prévus sur les parois intérieures des accoudoirs .A cardboard tubular mandrel 102 is disposed at the angle formed by the seat wall 32 and the back wall 30 and its ends penetrate into circular holes 104 provided on the interior walls of the armrests.
Une troisième barre de renfort 106 est prévue au niveau de la partie inférieure du dossier et ses extrémités pénètrent dans des trous 108 formés sur les parois intérieures des accoudoirs.A third reinforcement bar 106 is provided at the lower part of the backrest and its ends penetrate holes 108 formed on the interior walls of the armrests.
Enfin, une quatrième barre de renfort 110 est disposée dans l'angle formé entre la paroi d'épaisseur de dossier 28 et la paroi de retour 26 et ses extrémités pénétrant dans des trous 111 formés sur les parois intérieures 66. Bien entendu, les trous 96, 100, 104, sont situés sur une même ligne que la fente 86 et de même les trous 108 et 111 sont sur la même ligne que la fente (88), ces deux lignes formant entre elles un angle obtus .Finally, a fourth reinforcing bar 110 is disposed in the angle formed between the back thickness wall 28 and the return wall 26 and its ends penetrating holes 111 formed on the interior walls 66. Of course, the holes 96, 100, 104, are located on the same line as the slot 86 and similarly the holes 108 and 111 are on the same line as the slot (88), these two lines forming an obtuse angle between them.
L'assemblage de l'assise aux deux accoudoirs s'effectue de la façon suivante : on commence par mettre en place le mandrin 102 et les tubes de renfort 94, 98, 106 et 110 en introduisant leurs extrémités dans les trous respectifs formés sur les faces en regard 65 des accoudoirs. On plie ensuite le flan d'assise 17 de manière à ce que la paroi d'assise 32 forme avec la paroi de dossier 30 un angle obtus, que la paroi 34 soit repliée vers le bas et que les parois 28 et 26 soient repliées vers l'arrière. Le flan ainsi plié est déposé sur les barres de renfort. On insère alors les languettes 36, 38 dans les fentes 88, les languettes 40, 42 dans les fentes 86 et les languettes en forme de crochet 44, 46 et 48, 50 dans les fentes 92, 90.The assembly of the seat with the two armrests is carried out in the following way: one starts by positioning the mandrel 102 and the reinforcement tubes 94, 98, 106 and 110 by introducing their ends into the respective holes formed on the facing faces 65 of the armrests. The seat blank 17 is then folded so that the seat wall 32 forms an obtuse angle with the back wall 30, the wall 34 is folded down and the walls 28 and 26 are folded towards the back. The blank thus folded is deposited on the reinforcing bars. The tongues 36, 38 are then inserted into the slots 88, the tongues 40, 42 in the slots 86 and the hook-shaped tongues 44, 46 and 48, 50 in the slots 92, 90.
Les parois d'épaisseur 26 et 34 donnent une illusion d'épaisseur au dossier et à l'assise.The thick walls 26 and 34 give an illusion of thickness to the backrest and the seat.
On obtient ainsi un siège rigide et indéformable capable de résister à la pression du poids du corps d'un utilisateur.A rigid and non-deformable seat is thus obtained capable of withstanding the pressure of the weight of the body of a user.
Etant donné que ce siège a été réalisé uniquement par pliage et sans colle, il peut être démonté. Les trois éléments du siège peuvent être soit mis à plat, soit repliés pour obtenir un volume compact facile à transporter.Since this seat was made only by folding and without glue, it can be dismantled. The three elements of the seat can either be laid flat or folded to obtain a compact volume that is easy to transport.
La figure 6 montre par exemple la manière dont on peut transporter le siège sous sa forme démontée compacte. Les deux caisses constituant les accoudoirs sont accolées par leurs faces extérieures 64 et leurs extrémités sont insérées à l'intérieur d'un réceptacle parallélépipédique en carton 112. Sur les parois 68 des flans d'accoudoirs 52, 53 sont prévus deux évidements 114, 116. Dans la position représentée sur la figure 6 , ces deux évidements se placent côte à côte, ce qui permet à un utilisateur d'y passer des doigts afin de pouvoir transporter l'ensemble. II va de soi que le même principe de construction selon l'invention s'applique également à la réalisation aussi bien d'un fauteuil que d'un canapé, le canapé n'étant qu'une variante plus allongée de celle du fauteuil. Figure 6 shows for example how one can transport the seat in its compact disassembled form. The two boxes constituting the armrests are joined by their outer faces 64 and their ends are inserted inside a rectangular cardboard receptacle 112. On the walls 68 of the armrest blanks 52, 53 are provided two recesses 114, 116. In the position shown in Figure 6, these two recesses are placed side by side, which allows a user to pass their fingers in order to transport the assembly. It goes without saying that the same construction principle according to the invention also applies to the production of both an armchair and a sofa, the sofa being only a more elongated variant of that of the armchair.
