The sheet is provided with a control part for controlling the folding of sheet such that the sheet is folded along foldable lines into the seat for forming the surface and the foot when the part is activated. The part is organized for rolling back the zones in a manner perpendicular to the surface, where the seat is redeployed into the sheet when the control part ceases its effect.

Description

L'invention concerne un siège, tel qu'un tabouret pliable.The invention relates to a seat, such as a folding stool.

Les sièges, tels que les chaises et tabourets pliables sont bien connus dans l'état de la technique. Par exemple, le brevet américain US 2002/0043866 propose un dispositif constitué d'une feuille plate sur laquelle sont disposées une pluralité de lignes de pliage. Ces lignes de pliage définissent le contour d'une surface d'assise, d'une pluralité de parties de pied et d'une pluralité de parties de voile toutes contiguës les unes aux autres. La feuille peut être pliée selon les lignes de pliage pour former un tabouret que l'on peut placer sur une surface de support, la surface d'assise étant à distance de la surface de support, les pieds s'étendant de la surface d'assise à la surface de support, et les parties de voile adjacentes étant fixées les unes aux autres. La feuille est réalisée en un matériau flexible fin mais solide tel que du carton.Seats, such as folding chairs and stools are well known in the state of the art. For example, the US patent US 2002/0043866 proposes a device consisting of a flat sheet on which are arranged a plurality of fold lines. These fold lines define the outline of a seating surface, a plurality of foot portions and a plurality of sail portions all contiguous with each other. The sheet can be folded along the fold lines to form a stool that can be placed on a support surface, the seating surface being away from the support surface, the feet extending from the surface of the sitting on the support surface, and the adjacent web portions being secured to one another. The sheet is made of a thin but strong flexible material such as cardboard.

Ce dispositif est léger et, dans son état déplié, présente un très faible encombrement, ce qui le rend facile à stocker et à transporter. Mais ce siège pliable présente cependant un inconvénient, en ce que, pour pouvoir former le tabouret, il faut fixer les parties de voiles les unes aux autres au moyen d'un écrou et d'un boulon, de fermoirs à pression etc..., ce qui rend l'opération de montage malaisée. En effet, l'utilisateur devra tout d'abord plier la feuille selon les lignes de pliage, puis mettre en oeuvre les moyens de fixation ce qui est relativement difficile et résulte en une perte de temps, qui peut être préjudiciable, particulièrement lorsque l'on doit monter un grand nombre de tabourets comme par exemple lors d'une manifestation ponctuelle. De plus, dans sa forme dépliée, ce dispositif ne présente aucune application.This device is lightweight and, in its unfolded state, has a very small footprint, which makes it easy to store and transport. But this foldable seat has a drawback, in that, to be able to form the stool, it is necessary to fix the parts of the sails to each other by means of a nut and a bolt, snap fasteners etc ... , which makes editing difficult. Indeed, the user will first of all have to fold the sheet according to the fold lines, then implement the fixing means which is relatively difficult and results in a waste of time, which can be detrimental, particularly when the you have to assemble a lot of stools, for example during a specific event. In addition, in its unfolded form, this device has no application.

Le but de la présente invention est donc de remédier à ces inconvénients en proposant un siège, tel qu'un tabouret, pliable, léger, pratique et facile d'utilisation, qui, dans son état déplié présente aussi une fonction, notamment en faisant office de tapis, et se plie en un tabouret par une opération unique ne nécessitant aucune manipulation complexe du tabouret par l'utilisateur. De plus, du fait de la simplicité de sa mise en oeuvre, ce siège est économiquement avantageux.The object of the present invention is therefore to overcome these disadvantages by providing a seat, such as a stool, foldable, lightweight, practical and easy to use, which, in its unfolded state also has a function, especially by acting of carpet, and folds into a stool by a single operation requiring no complex manipulation of the stool by the user. In addition, because of the simplicity of its implementation, this seat is economically advantageous.

A cet effet, l'invention a pour objet un siège, tel qu'un tabouret, pliable constitué d'une feuille de matériau plane présentant une pluralité de lignes de pliage définissant les contours d'une surface d'assise centrale, de pieds et de parties en ailettes entre les pieds, caractérisé en ce que ladite feuille est constituée d'un matériau souple et flexible et comporte en outre au niveau de la zone correspondant aux dits pieds et à ladite surface d'assise au moins une couche de matériau rigide, la feuille plane étant pourvue de moyens de commande du pliage de la feuille, de sorte que, lorsqu'on actionne lesdits moyens de commande du pliage, la feuille se plie selon lesdites lignes de pliage pour former la surface d'assise et les pieds d'un siège, les moyens de commande de pliage étant agencés pour replier les zones correspondant aux pieds de manière sensiblement perpendiculaire à la surface d'assisse, et lorsque les moyens de commande cessent leur effet, le siège se redéploie en feuille.To this end, the subject of the invention is a seat, such as a stool, foldable consisting of a sheet of flat material having a plurality of fold lines defining the contours of a central seating surface, feet and parts in fins between the feet, characterized in that said sheet is made of a flexible and flexible material and further comprises at the area corresponding to said feet and said seat surface at least one layer of rigid material the flat sheet being provided with means for controlling the folding of the sheet, so that when said folding control means is actuated, the sheet folds along said fold lines to form the seating surface and the feet a seat, the folding control means being arranged to fold the areas corresponding to the feet substantially perpendicular to the seating surface, and when the control means cease their effect, the seat is re unfolds in sheet.

Ainsi, de manière très avantageuse, dans son état déplié, le siège pliable selon l'invention se présente sous la forme d'une feuille de matériau plan, assimilable à un tapis, sur lequel l'utilisateur peut s'étendre ou s'asseoir, lui évitant d'avoir à être en contact avec le sol. L'utilisateur peut à tout moment convertir le tapis en un tabouret par une opération très simple consistant à actionner les moyens de commande qui entraîne le pliage permettant de réaliser le siège pliable selon l'invention.Thus, very advantageously, in its unfolded state, the folding seat according to the invention is in the form of a sheet of plane material, similar to a carpet, on which the user can extend or sit , avoiding him having to be in contact with the ground. The user can at any time convert the carpet into a stool by a very simple operation of operating the control means which causes folding to achieve the folding seat according to the invention.

Ainsi, le siège selon l'invention est constitué d'une feuille plane munie d'une pluralité de lignes de pliages formées sur ladite feuille. Les lignes de pliage définissent les contours d'une surface d'assise centrale, d'une pluralité de pieds et de parties souples en ailettes ménagées entre les pieds. Ces lignes de pliage sont les lignes de pliages principales qui peuvent être formées, par exemple par nervurage, par couture ou tout autre procédé approprié.Thus, the seat according to the invention consists of a flat sheet provided with a plurality of fold lines formed on said sheet. The fold lines define the contours of a central seating surface, a plurality of feet, and flexible vanes formed between the legs. These fold lines are the main fold lines that can be formed, for example by ribbing, sewing or any other suitable method.

De préférence, la feuille plane est réalisée en un matériau souple et flexible tel qu'une mousse à haute résilience, pouvant notamment être enfermée dans une enveloppe de tissu souple. Les zones correspondant aux pieds et à la surface d'assise comportent, en outre, un matériau rigide tel que du contre-plaqué, du carton plat ou tout autre matériau approprié conférant la rigidité voulue. On peut prévoir de fixer, par exemple par collage, ce matériau rigide sur la face de dessous de la feuille, ou bien encore de l'insérer entre deux couches de matériau flexible constituant la feuille, ou encore de le mettre en place dans l'enveloppe souple renfermant une couche de mousse.Preferably, the flat sheet is made of a flexible and flexible material such as a high-resilience foam, which can be enclosed in a flexible fabric envelope. The areas corresponding to the feet and the seat surface further include a rigid material such as plywood, flat board or any other suitable material conferring the desired rigidity. It is possible to fix, for example by gluing, this rigid material on the underside of the sheet, or alternatively insert it between two layers of flexible material constituting the sheet, or to put it in place in the flexible envelope enclosing a layer of foam.

Enfin, il est également possible de personnaliser l'invention en fixant sur la feuille plane un revêtement adapté constitué d'un matériau également flexible.Finally, it is also possible to customize the invention by fixing on the flat sheet a suitable coating made of a material also flexible.

Dans un mode de réalisation préféré, la zone correspondant à la surface d'assise et aux pieds forme une croix constituée sensiblement de deux rectangles dont l'intersection forme la partie centrale définissant la surface d'assise du siège plié, et dont les branches définissent les zones formant pied. Les surfaces libres ou parties en ailette situées entre les branches de la croix sont au nombre de quatre et ont de préférence leur bord libre sensiblement circulaire.In a preferred embodiment, the area corresponding to the seating surface and feet forms a cross consisting substantially of two rectangles whose intersection forms the central portion defining the seating surface of the folded seat, and whose branches define the foot zones. The free surfaces or fin parts located between the branches of the cross are four in number and preferably have their substantially circular free edge.

Selon ce mode de réalisation préféré de l'invention, les lignes de pliages principales sont définies le long des rectangles qui constituent la croix comportant le matériau rigide et sont matérialisées par une couture.According to this preferred embodiment of the invention, the main fold lines are defined along the rectangles which constitute the cross comprising the rigid material and are materialized by a seam.

De préférence, les moyens de commande du pliage sont constitués d'une pluralité d'organes de commande flexibles tels que cordes, filins ou similaires, fixés, à une extrémité, sur la face du dessous de la feuille, aux zones formant pieds et, à l'extrémité opposée, à un organe de préhension tel qu'une poignée, situé sur la face du dessus de la feuille plane, au travers d'un orifice central de la feuille.Preferably, the folding control means are constituted by a plurality of flexible control members such as ropes, ropes or the like, fixed at one end to the underside of the sheet, to the foot zones and, at the opposite end, to a gripping member such as a handle, located on the top face of the flat sheet, through a central orifice of the sheet.

Ainsi, lorsque l'on tire sur la poignée, on tire sur les organes de commande, qui, fixés aux zones formant pieds, amènent ces dernières à se plier selon les lignes de pliage situées le long des contours de la surface d'assise pour replier lesdits pieds perpendiculairement à la surface d'assise, chaque partie en ailette faisant saillie librement vers l'extérieur entre deux pieds adjacents, pour former un siège. Les points où ces organes de commande sont reliés aux zones formant pieds sont situés, sensiblement aux 2/3 de la hauteur du pied, de façon à assurer la plus grande stabilité au tabouret.Thus, when the handle is pulled, the control members, which, fixed to the zones forming the feet, cause the latter to bend along the fold lines situated along the contours of the seating surface for folding said legs perpendicular to the seating surface, each fin portion projecting outwardly between two adjacent legs to form a seat. The points where these control members are connected to the foot zones are located substantially at 2/3 of the height of the foot, so as to ensure greater stability to the stool.

Selon un mode de réalisation préféré, la surface d'assise est parallélépipédique, de préférence carrée, et les organes de commande flexibles sont au nombre de quatre, et fixés chacun à une de leurs extrémités à un sommet d'un carré de pliage ayant le même centre que la surface d'assise et dont les milieux des côtés sont les sommets de la surface d'assise. Les organes de commande sont en outre reliés à la poignée au travers d'un orifice ménagé au centre de la surface d'assise. De ce fait, les organes flexibles sont tous de la même longueur. Toutefois, lorsque la surface d'assise est de section rectangulaire par exemple, la longueur des organes flexibles est déterminée pour permettre le pliage correspondant.According to a preferred embodiment, the seating surface is parallelepipedal, preferably square, and the flexible control members are four in number, and each fixed at one of their ends to an apex of a folding square having the same center as the seating surface and whose middle sides are the tops of the seating surface. The control members are further connected to the handle through an orifice in the center of the seating surface. As a result, the flexible members are all of the same length. However, when the seat surface is of rectangular section for example, the length of the flexible members is determined to allow the corresponding folding.

Les moyens de commande du pliage comportent en outre un moyen de verrouillage, permettant de verrouiller les organes de commande en position pliée du siège. Ainsi, le moyen de verrouillage est constitué d'une encoche ménagée à la périphérie de la surface d'assises et dans laquelle les organes de commande flexibles sont engageables de sorte que la poignée vienne en butée contre l'encoche. Ainsi, on bloque les moyens de commande en position repliée du siège. Ce tabouret est alors rigide et stable de sorte qu'un adulte pourra s'asseoir. Il suffira à l'utilisateur de libérer les organes de commande et la poignée hors du moyen de verrouillage pour que le tabouret se redéploie en un tapis.The folding control means further comprise a locking means for locking the control members in the folded position of the seat. Thus, the locking means is constituted by a notch formed at the periphery of the seating surface and wherein the flexible control members are engageable so that the handle abuts against the notch. Thus, the control means is locked in the folded position of the seat. This stool is then rigid and stable so that an adult can sit. It will be sufficient for the user to release the control members and the handle out of the locking means so that the stool redeploys into a carpet.

On peut également envisager de prévoir des moyens de commande de pliage comprenant des tiges rigides articulées fixées sur la face du dessous de la feuille, en particulier le long des lignes de pliages principales, des organes de commande flexibles étant fixés auxdites tiges pour provoquer leur pliage et leur dépliage.It is also conceivable to provide folding control means comprising articulated rigid rods fixed on the underside of the sheet, in particular along the main fold lines, flexible control members being fixed to said rods to cause them to bend. and unfolding them.

Les lignes de pliage principales de la feuille plane situées le long des contours de la surface d'assise centrale, des pieds et des parties en ailettes permettront le pliage du siège. Néanmoins, on peut prévoir des lignes de pliage supplémentaires, destinées à renforcer la stabilité du siège une fois monté, par exemple en prévoyant des lignes de pliage de renfort passant par le point de fixation entre l'organe de commande et le pied correspondant. Ainsi, dans un mode de réalisation préféré de l'invention, des lignes de pliage supplémentaires sont prévues le long des côtés du carré de pliage, ainsi que le long de quatre segments parallèles aux membres de la croix centrale et s'étendant entre les sommets du carré de pliage et les extrémités des membres de ladite croix.The main folding lines of the flat sheet located along the contours of the central seating surface, feet and wing portions will allow the seat to be folded. Nevertheless, it is possible to provide additional fold lines, intended to reinforce the stability of the seat once mounted, for example by providing reinforcing fold lines passing through the point of attachment between the control member and the corresponding foot. Thus, in a preferred embodiment of the invention, additional fold lines are provided along the sides of the fold square, as well as the along four segments parallel to the members of the central cross and extending between the vertices of the folding square and the ends of the members of said cross.

La présente invention va maintenant être décrite plus en détails à l'aide des dessins annexés illustrant un mode de réalisation préféré dans lesquels:

  • la figure 1 est une vue de dessous du siège pliable selon l'invention dans son état déplié (tapis) ; et
  • la figure 2 est une vue en coupe du siège de la figure 1 en cours de pliage.
The present invention will now be described in more detail with the aid of the accompanying drawings illustrating a preferred embodiment in which:
  • Figure 1 is a bottom view of the foldable seat according to the invention in its unfolded state (carpet); and
  • Figure 2 is a sectional view of the seat of Figure 1 during bending.

La figure 1 illustre le dispositif selon un mode de réalisation préféré de l'invention dans son état déplié, formant un tapis. Le siège se présente comme une feuille 1 plane comprenant au moins une couche de matériau flexible et souple 10 tel qu'une mousse à haute résilience. Cette mousse est ici enfermée dans une enveloppe 11, par exemple en tissu. Dans cette feuille 1, est définie une zone ayant la forme d'une croix à base de deux rectangles 2, 2' se croisant à angle droit, définissant la surface d'assise 3 en forme de carré C et quatre zones formant les pieds 4 du tabouret. Cette zone en forme de croix est définie par des couches 12 de contre-plaqué insérées dans l'enveloppe 11 sur la face du dessous de la couche 10 de mousse à haute résilience. Les parties en ailettes 5 définies entre les branches 4 de la croix ont leur bord libre sensiblement circulaire. Le tapis présente ici une forme sensiblement de carré aux angles arrondis.Figure 1 illustrates the device according to a preferred embodiment of the invention in its unfolded state, forming a carpet. The seat is in the form of a flat sheet 1 comprising at least one layer of flexible and flexible material 10 such as a high-resilience foam. This foam is here enclosed in an envelope 11, for example fabric. In this sheet 1 is defined a zone having the shape of a cross based on two rectangles 2, 2 'intersecting at right angles, defining the seating surface 3 in the form of a square C and four zones forming the feet 4 of the stool. This cross-shaped area is defined by layers 12 of plywood inserted into the envelope 11 on the underside of the layer 10 of high resilience foam. The parts in fins 5 defined between the branches 4 of the cross have their substantially circular free edge. The carpet here has a substantially square shape with rounded corners.

La feuille 1 présente des lignes de pliage principales 6 matérialisées par des coutures le long des rectangles constituant la croix, c'est-à-dire sur les contours de la surface d'assise 3 et des branches 4 de la croix. Les moyens de commande du pliage sont constitués de quatre organes de commande flexibles 7 tels que des cordes dont une extrémité est fixée, sur une zone formant pied 4, sensiblement aux 2/3 de la hauteur du pied, au voisinage d'un sommet d'un carré de pliage C' ayant le même centre que la croix et dont les milieux des côtés sont les sommets du carré d'assise C. L'autre extrémité des organes de commande 7 est fixée à une poignée 9, les organes de commandes 7 passant au travers d'un orifice ménagé au centre de la surface d'assise 3.The sheet 1 has main fold lines 6 materialized by seams along the rectangles constituting the cross, that is to say on the contours of the seating surface 3 and the branches 4 of the cross. The folding control means consist of four flexible control members 7 such as cords whose one end is fixed on a foot zone 4, substantially at 2/3 of the height of the foot, in the vicinity of a vertex d. a folding square C 'having the same center as the cross and whose sides of the sides are the vertices of the seat square C. The other end of the control members 7 is fixed to a handle 9, the control members 7 passing through a hole in the center of the seating surface 3.

La longueur de chaque organe flexible 7 est définie pour que chaque zone formant pied 4 soit repliée perpendiculairement à la surface d'assise 3 par une course unique de la poignée 9. De cette façon, la surface d'assise 3 peut être parallélépipédique à section carrée ou rectangulaire ou autre. De même on peut envisager également que la surface d'assise soit de section circulaire, les lignes de pliage étant définies en conséquence.The length of each flexible member 7 is defined so that each foot zone 4 is folded perpendicular to the seat surface 3 by a single stroke of the handle 9. In this way, the seat surface 3 can be parallelepiped section square or rectangular or other. Similarly one can also consider that the seating surface is of circular section, the fold lines being defined accordingly.

Enfin, des lignes de pliages supplémentaires de renfort 8 sont prévues le long des côtés du carré de pliage C', ainsi qu'entre les sommets du carré de pliage et les extrémités des branches 4 de la croix.Finally, additional fold lines of reinforcement 8 are provided along the sides of the folding square C 'and between the vertices of the fold square and the ends of the branches 4 of the cross.

La figure 2 illustre le même dispositif en phase de pliage plié en un tabouret. Les pieds du tabouret sont en cours de pliage perpendiculairement à la surface d'assise 3, et les parties en ailettes 5 font saillie. En tirant sur la poignée 9, on a également entraîné les organes de commande 7, reliés à la poignée, vers l'extérieur, au travers de l'orifice prévu au centre de la surface d'assise 3. Les quatre organes de commande 7 sont ainsi en contact les uns avec les autres entre la poignée 9 et l'orifice central. Par contre, les organes de commande 7 ne sont plus en contact avec la feuille 1 qu'entre l'orifice central et les points de fixation avec les pieds du tabouret. Tendus chacun entre ces deux points, ces organes de commande 7 assurent le pliage du tabouret.Figure 2 illustrates the same device in folding phase folded into a stool. The legs of the stool are being folded perpendicularly to the seating surface 3, and the wing portions 5 protrude. By pulling on the handle 9, the control members 7, connected to the handle, have also been driven outwards through the orifice provided in the center of the seat surface 3. The four control members 7 are thus in contact with each other between the handle 9 and the central orifice. On the other hand, the control members 7 are no longer in contact with the sheet 1 only between the central orifice and the points of attachment with the feet of the stool. Stretched each between these two points, these control members 7 ensure the folding of the stool.

De manière à permettre le maintien en position pliée du siège selon l'invention, on prévoit un moyen de verrouillage de la position pliée du siège. Ce moyen de verrouillage est de préférence constitué d'une encoche ménagée à la périphérie de la surface d'assise 3 et dans laquelle on insère les organes de commande flexibles, la poignée 9 venant en butée à l'extérieur de l'encoche.In order to allow the seat in the folded position of the seat according to the invention to be maintained, a means for locking the folded position of the seat is provided. This locking means is preferably constituted by a notch formed at the periphery of the seat surface 3 and into which the flexible control members are inserted, the handle 9 abutting the outside of the notch.

Tout autre moyen de verrouillage est également approprié.Any other locking means is also appropriate.

Il va de soi que la forme de réalisation de l'invention qui a été décrite ci-dessus a été donnée à titre purement indicatif et nullement limitatif, et que de nombreuses modifications peuvent être facilement apportées par l'homme de l'art sans pour autant sortir du cadre de l'invention.It goes without saying that the embodiment of the invention which has been described above has been given for information only and in no way limiting, and that many modifications can easily be made by those skilled in the art without as far out of the scope of the invention.
