L'invention concerne un siège en carton du genre tabouret. The invention relates to a stool-type cardboard seat.

Elle a pour but la réalisation d'un siège de solidité éprouvee, particulièrement leger et facile à déplacer, susceptible d'être stocké à plat et monté sans difficulté par toute personne
L'invention a pour objet un siège, obtenu par découpe et rainage d'un flan de carton, caractérisé en ce qu'il comporte une ceinture à deux faces planes et deux faces pliables alternées, constituant la surface latérale du siège ; et deux volets portes par les faces planes, susceptibles de constituer la surface superieure du tabouret, et portant chacun un rabat susceptible d'être replie vers l'intérieur du siège et de coopérer avec les faces pliables pour assurer le montage du siège.
Its purpose is to produce a seat of proven solidity, particularly light and easy to move, capable of being stored flat and assembled without difficulty by any person.
The subject of the invention is a seat, obtained by cutting and creasing a cardboard blank, characterized in that it comprises a belt with two flat faces and two alternating foldable faces, constituting the lateral surface of the seat; and two flaps doors by the flat faces, capable of constituting the upper surface of the stool, and each carrying a flap capable of being folded towards the interior of the seat and of cooperating with the foldable faces to ensure the mounting of the seat.

Selon d'autres caractéristiques de l'invention
- les faces pliables sont munies en leur milieu d'une ligne de pliage presentant à sa partie supérieure une encoche susceptible de recevoir lesdits rabats,
- les faces pliables portent des rabats supérieurs également pliables et destinés à être repliés contre lesdites faces vers l'intérieur du siège, pour en augmenter sa rigidité,
- les volets articulés sur les faces planes constituent chacun une moitié de la face supérieure du siège,
- les rabats portés par lesdits volets présentent deux encoches à mi-profondeur, susceptibles de coopérer chacune avec l'encoche d'une face pliable,
- l'angle de.pliage des faces pliables est d'environ 1200.
According to other features of the invention
the foldable faces are provided in their middle with a fold line having at its upper part a notch capable of receiving said flaps,
the foldable faces carry upper flaps which are also foldable and intended to be folded against said faces towards the inside of the seat, to increase its rigidity,
- the flaps articulated on the flat faces each constitute one half of the upper face of the seat,
the flaps carried by said flaps have two notches at mid-depth, each capable of cooperating with the notch of a foldable face,
- the angle of folding of the foldable faces is approximately 1200.

D'autres caracteristiques de l'invention ressortent de la description qui suit faite avec référence au dessin annexé sur lequel on peut voir
Figure 1, une vue à plat d'un flan découpé et rainé pour constituer un siège selon l'invention ;
Figure 2, une vue perspective du siège obtenu après montage à partir du flan de la figure 1.
Other characteristics of the invention will emerge from the description which follows, made with reference to the appended drawing in which one can see
Figure 1, a flat view of a blank cut and grooved to form a seat according to the invention;
Figure 2, a perspective view of the seat obtained after mounting from the blank of Figure 1.

En se reportant au dessin, on peut voir que le siege selon l'invention est essentiellement constitué d'une ceinture de quatre faces portant des volets d'un seul coté, et assembles grâce à une languette 1. Referring to the drawing, it can be seen that the seat according to the invention essentially consists of a belt of four faces carrying flaps on one side only, and assembled using a tongue 1.

Les quatre faces sont respectivement deux faces planes 2 et 3 en regard l'une de l'autre dans le siège monté, et deux faces 4 et 5 pliables en leur milieu, le long de lignes de pliage 6 et 7 respectivement. Ainsi la face 4 se compose de deux demi-faces 8 et 9 séparées par la ligne de pliage 6,et la face 5 se compose de deux demi-faces 10 et 11 séparées par la ligne 7. The four faces are respectively two plane faces 2 and 3 facing each other in the mounted seat, and two faces 4 and 5 foldable in the middle, along fold lines 6 and 7 respectively. Thus the face 4 is made up of two half-faces 8 and 9 separated by the fold line 6, and the face 5 is made up of two half-faces 10 and 11 separated by the line 7.

Les lignes d'articulation entre les diverses faces 2 à 5 sont des lignes de rainage, et les lignes de pliage 6 et 7 sont en fait des lignes de rainage inversé. The articulation lines between the various faces 2 to 5 are crease lines, and the fold lines 6 and 7 are in fact inverted crease lines.

Les faces planes 2 et 3 portent respectivement des volets 12, 13 sur lesquels s'articulent respectivement des rabats 14, 15. The flat faces 2 and 3 respectively carry flaps 12, 13 on which flaps 14, 15 are articulated respectively.

Ces rabats sont munis chacun de deux encoches 16, 17 et 18, 19 respecti vexent. Par ailleurs, leurs bords latéraux sont obliques de façon à s'effacer sous la surface supérieure du siège tout en assurant le support des bords latéraux de cette surface correspondant aux faces pliables 4 et 5.These flaps are each provided with two notches 16, 17 and 18, 19 respectively. Furthermore, their lateral edges are oblique so as to disappear under the upper surface of the seat while ensuring the support of the lateral edges of this surface corresponding to the foldable faces 4 and 5.

Les faces pliables 4 et 5 portent* par l'intermédiaire d'une bande de rattrapage d'épaisseur 20, 21 respectivement, des rabats supérieurs 22 et 23 respectivement. Ces rabats présentent une ligne de pliage 24, 25 respectivement, dans le prolongement de la ligne de pliage 6, 7 respectivement, des faces 4 et 5. Sur ces lignes de pliage 24, 25, sont disposées des lumières 26, 27 respectivement pour faciliter le pliage des rabats supérieurs lors du montage du siège. The foldable faces 4 and 5 carry * via a take-up strip of thickness 20, 21 respectively, upper flaps 22 and 23 respectively. These flaps have a fold line 24, 25 respectively, in the extension of the fold line 6, 7 respectively, faces 4 and 5. On these fold lines 24, 25, are arranged lights 26, 27 respectively to facilitate folding the upper flaps when mounting the seat.

A cheval sur les bandes de rattrapage d'épaisseur 20, 21, sont prévues des découpes, dans l'axe des lignes de pliage 6-24 d'une part et 7-25 d'autre part. Ces decoupes, 28 et 29 respectivement, symétriques par rapport aux bandes 20 et 21, définissent des encoches sur les faces pliables et sur les rabats supérieurs, encoches qui, après montage du siège, ont la même profondeur et coopèrent avec les encoches des rabats 14 et 15. La decoupe 28 définit ainsi les encoches 30 sur la face 4 et 31 sur le rabat supérieur 22. De même la découpe 29 définit les encoches 32 et 33 sur la face 5 et le rabat 23 respectivement. Straddling the take-up strips of thickness 20, 21, there are provided cutouts, in the axis of the fold lines 6-24 on the one hand and 7-25 on the other. These cutouts, 28 and 29 respectively, symmetrical with respect to the strips 20 and 21, define notches on the foldable faces and on the upper flaps, notches which, after mounting of the seat, have the same depth and cooperate with the notches of the flaps 14 and 15. The cutout 28 thus defines the notches 30 on the face 4 and 31 on the upper flap 22. Similarly the cutout 29 defines the notches 32 and 33 on the face 5 and the flap 23 respectively.

Pour l'assemblage du siège, la ceinture est constituée en collant la languette 1 sous le bord libre de la face 5. Les volets et rabats étant tous du même côté, l'ensemble est livrable à plat et susceptible d'être stocké à plat. Au moment de l'utilisation, il faut monter le siège. A cet effet, on met en forme le pied du siège en écartant les faces les unes des autres. On replie les rabats supérieurs 22 et 23 vers l'intérieur contre les faces 4 et 5 respectivement.On rapproche vers l'intérieur les lignes de pliage 6 et 7 en pliant les faces 4 et 5 jusqu'à ce que l'angle entre les demi-faces 8 et 9 d'une part, 10 et 11 d'autre part, soit d'environ 1200. On replie vers l'intérieur les rabats 14, 15 par rapport aux volets 12, 13 qui les portent, et on rabat le tout vers l'intérieur de façon que les faces extérieures des rabats 14 et 15 viennent en appui l'une sur l'autre. On fait descendre les rabats 14 et 15 de façon que les encoches 16 et 19 d'une part, 17 et 18 d'autre part, cooperent avec les encoches 32 et 33 d'une part, 30 et 31 d'autre part, respectivement. For the assembly of the seat, the belt is made by sticking the tongue 1 under the free edge of the face 5. The flaps and flaps are all on the same side, the set is available flat and can be stored flat . At the time of use, the seat must be fitted. For this purpose, the foot of the seat is shaped by spreading the faces of each other. The upper flaps 22 and 23 are folded inwards against the faces 4 and 5 respectively. The fold lines 6 and 7 are brought inwards by folding the faces 4 and 5 until the angle between the half-faces 8 and 9 on the one hand, 10 and 11 on the other hand, that is to say approximately 1200. The flaps 14, 15 are folded inwards relative to the flaps 12, 13 which carry them, and the flap is folded all inwardly so that the outer faces of the flaps 14 and 15 come to bear one on the other. The flaps 14 and 15 are lowered so that the notches 16 and 19 on the one hand, 17 and 18 on the other hand, cooperate with the notches 32 and 33 on the one hand, 30 and 31 on the other hand, respectively .

Lorsque les fonds d'encoches sont en appui respectif, les volets 12 et 13 sont horizontaux, et ils constituent la face supérieure du siege. When the notch bottoms are in respective support, the flaps 12 and 13 are horizontal, and they constitute the upper face of the seat.

Les faces latérales 2 à 5 reposent sur le sol par leur bord libre et donnent un appui stable et satisfaisant. Les rabats supérieurs 22 et 23 renforcent à l'intérieur les faces pliables 4 et 5 et augmentent la rigidité du siège. Les volets 12 et 13 reposent sur les bandes de rattrapage d'épaisseur 20 et 21 et ont un appui stable du fait du pli vers l'intérieur des faces 4 et 5. Par ailleurs, les rabats 14 et 15 portent sur le fond des encoches prévues dans les faces pliables 4 et 5. The lateral faces 2 to 5 rest on the ground by their free edge and give a stable and satisfactory support. The upper flaps 22 and 23 reinforce the foldable faces 4 and 5 inside and increase the rigidity of the seat. The flaps 12 and 13 rest on the thickness take-up strips 20 and 21 and have a stable support due to the fold inwards of the faces 4 and 5. Furthermore, the flaps 14 and 15 bear on the bottom of the notches provided in foldable faces 4 and 5.

Le siège selon l'invention est avantageusement réalise en carton ondulé à double cannelure par exemple. Dans ce cas le sens des cannelures est bien entendu le sens des lignes de pliage 6, 7 pour assurer au pied du siege la meilleure résistance à l'écrasement. The seat according to the invention is advantageously made of corrugated cardboard with double grooves for example. In this case the direction of the grooves is of course the direction of the fold lines 6, 7 to ensure the foot of the seat the best resistance to crushing.

Le siege selon l'invention est remarquable par la simplicité de sa découpe, par la facilité de son montage, par sa résistance mécanique et par sa légèreté qui permet une grande maniabilité.  The seat according to the invention is remarkable for the simplicity of its cutting, for the ease of its assembly, for its mechanical strength and for its lightness which allows great maneuverability.
