Description

Domaine de l'invention  Field of the invention
La présente invention concerne d'une façon générale le mobilier, et notamment les sièges à structure souple. Etat de la technique  The present invention relates generally to furniture, including seats with flexible structure. State of the art
On connaît déjà largement dans l'état de la technique des sièges comportant une enveloppe remplie de billes ou de morceaux ou copeaux de matériau à structure alvéolaire, de manière à pouvoir donner aux sièges une liberté de forme importante.  It is already widely known in the state of the art seats with an envelope filled with balls or chips or chips of honeycomb material, so as to give the seats a significant freedom of shape.
Suivant la nature et la géométrie de l'enveloppe et la densité du matériau de remplissage, la forme de tels sièges est plus ou moins libre.  Depending on the nature and the geometry of the envelope and the density of the filling material, the shape of such seats is more or less free.
On réalise ainsi des poufs, coussins, sièges avec dossier, dans les formes les plus diverses.  We thus realize poufs, cushions, seats with backrest, in the most diverse forms.
Un inconvénient de ces éléments de mobilier est qu'ils sont volumineux et parfois assez lourds, selon le type de matériau de remplissage.  A disadvantage of these furniture items is that they are bulky and sometimes quite heavy, depending on the type of filler material.
En effet, même si l'on connaît des procédés permettant de faire le vide à l'intérieur de l'enveloppe, de manière à réduire le volume de l'élément mobilier pour le transport, le gain de volume reste assez limité. En outre, le gain en poids est inexistant.  Indeed, even if there are known methods for evacuating the interior of the envelope, so as to reduce the volume of the movable item for transport, the volume gain remains quite limited. In addition, the weight gain is non-existent.
Par ailleurs, après remplissage d'un tel élément mobilier avec le matériau de remplissage, la rigidité ou la souplesse de l'élément est déterminée une fois pour toutes, et il est nécessaire d'ajouter ou d'enlever du matériau de remplissage pour ajuster ce facteur.  Furthermore, after filling such a furniture element with the filling material, the rigidity or flexibility of the element is determined once and for all, and it is necessary to add or remove filling material to adjust this factor.
On connaît par ailleurs des sièges, matelas, etc. comportant à la fois un volume destiné à contenir de l'air et un volume destiné à contenir un matériau de remplissage. Les documents BE413231A, US2942281A et US6592533B1 donnent des exemples de tels articles. Toutefois, ils ne donnent aucune indication sur des possibilités de limitation de volume à la manutention, et de permettent pas de restituer l'effet d'un coussin à la fois léger et à forme relativement libre. Résumé de l'invention We also know seats, mattresses, etc. comprising both a volume for containing air and a volume for containing a filling material. BE413231A, US2942281A and US6592533B1 give examples of such articles. However, they give no indication of the possibilities of limiting the volume of handling, and do not allow to restore the effect of a cushion both lightweight and relatively free shape. Summary of the invention
La présente invention vise à pallier tout ou partie des inconvénients précités, et en particulier à proposer un élément de mobilier qui ait les qualités propres à un coussin en termes de déformabilité et de confort (sans référence ici à la forme), tout en étant aisé à stocker, transporter et faire passer d'un état d'utilisation, de volume nominal, à un état de stockage et ou de transport d'un volume réduit, tout en étant simple et économique à fabriquer.  The present invention aims to overcome all or part of the aforementioned drawbacks, and in particular to provide a furniture item that has the qualities of a cushion in terms of deformability and comfort (without reference here to the form), while being easy storing, transporting and passing from a state of use, nominal volume, to a state of storage and / or transportation of a reduced volume, while being simple and economical to manufacture.

Description détaillée d'une forme de réalisation Figures 3 and 4 are perspective views from the rear of two details of a seat according to the invention, Figure 3 being a representation of an inner casing, and Figure 4 that of an outer casing. Detailed description of an embodiment
En référence aux figures 1 et 2, on a représenté un élément de mobilier sous la forme d'un siège de type fauteuil avec une assise A et un dossier D.  Referring to Figures 1 and 2, there is shown a furniture element in the form of a chair-type seat with a seat A and a folder D.
Une enveloppe extérieure 10 définit la forme générale du siège, avec une zone d'appui au sol 101 , une zone frontale 102, une zone d'assise 103, une zone de dossier 104, une zone de dessus de dossier 106, une zone de dos 105 et deux zones latérales, l'une 107 étant représentée sur la coupe de la figure 1 . Le matériau de l'enveloppe extérieure 10 est une membrane souple de préférence soudable et étanche à l'air, notamment en PVC.  An outer shell 10 defines the general shape of the seat, with a ground support area 101, a frontal area 102, a seating area 103, a backrest area 104, a backrest area 106, a seating area 105 and two side zones, one 107 being shown in the section of Figure 1. The outer lining material 10 is a soft membrane preferably weldable and airtight, in particular PVC.
A l'intérieur de l'enveloppe extérieure 10 se trouve une enveloppe intérieure 30, en un matériau étanche à l'air et soudable tel qu'une membrane de PVC. Cette enveloppe 30 sépare l'espace 20 défini globalement par l'enveloppe intérieure 10 en un premier volume 22, intérieur, délimité par ladite enveloppe 30, et un deuxième volume 21 , extérieur, entourant sensiblement entièrement le volume intérieur 22.  Inside the outer casing 10 is an inner casing 30 made of an airtight and weldable material such as a PVC membrane. This envelope 30 separates the space 20 defined globally by the inner envelope 10 into a first interior volume 22 delimited by said envelope 30, and a second external volume 21 surrounding substantially the entire interior volume 22.
L'enveloppe intérieure 30 est reliée à l'enveloppe extérieure 10 en un nombre limité de régions, et dans le présent exemple ici dans deux régions, à savoir une région R1 situé dans la partie frontale 103 et une région R2 située dans la partie de dessus de dossier 106. D'une façon générale, on prévoit des régions de liaisons en fonction de la forme recherchée pour l'élément, de façon à laisser une liberté importante de la forme de l'enveloppe extérieure 10 par rapport à la forme de l'enveloppe intérieure 30, comme on le verra dans la suite. D'une façon générale, deux régions de liaison dans des parties opposées de l'élément seront prévues. La liaison entre les deux enveloppes est effectuée de préférence par soudage des membranes pour les solidariser sur une surface de l'ordre de 50 à 500 cm2.  The inner envelope 30 is connected to the outer envelope 10 in a limited number of regions, and in the present example here in two regions, namely a region R1 located in the front portion 103 and a region R2 located in the portion of In general, connection regions are provided depending on the shape sought for the element, so as to leave a significant freedom in the shape of the outer envelope 10 with respect to the shape of the element. the inner envelope 30, as will be seen later. In general, two link regions in opposite parts of the element will be provided. The connection between the two shells is preferably performed by welding the membranes to secure them to a surface of the order of 50 to 500 cm 2.
On notera que la forme de l'enveloppe intérieure 30 à état gonflé (comme on le détaillera plus loin) est obtenue en soudant ensemble un ensemble de panneaux de formes particulières (dans le cas d'espèce deux panneaux, un panneau de dessus et un panneau de dessous et d'arrière), et en dotant le cas échéant les panneaux, notamment le panneau de dessus et le panneau de dessous et d'arrière, de lignes de rigidification (surépaisseurs de matière), de façon connue en soi dans le domaine des matelas et autres articles pneumatiques de loisirs. De même, l'enveloppe extérieure 10 peut être réalisée en soudant ensemble un certain nombre de panneaux, avec une forme générale semblable à celle de l'enveloppe intérieure, et une taille plus importante (typiquement de 20 à 50 % plus grande). Note that the shape of the inner envelope 30 inflated (as will be detailed below) is obtained by welding together a set of panels of particular shapes (in this case two panels, a panel and a top bottom and back panel), and by providing, where appropriate, the panels, in particular the top panel and the bottom and rear panel, of stiffening lines (material thicknesses), in a manner known per se in the field of mattresses and other recreational pneumatic articles. Similarly, the outer casing 10 can be made by welding together a number of panels, with a general shape similar to that of the inner casing, and a larger size (typically 20 to 50% larger).
Comme mieux visible sur les figures 3 et 4, le volume intérieur 22 communique avec l'extérieur par un bouchon étanche, par exemple de type embout de gonflage utilisé dans le domaine précité des articles pneumatiques, ce bouchon 40 étant de préférence situé au sein de l'une des régions R1 et R2 de façon à pouvoir traverser simultanément l'épaisseur de matière de l'enveloppe extérieure 10 et l'épaisseur de matière de l'enveloppe intérieure 30. Ce bouchon permet d'appliquer une pression d'air ou autre gaz, ajustable au sein du volume intérieur 22, et de vider pratiquement entièrement ce volume intérieur. Le bouchon 40 comprend avantageusement une valve anti-retour, de façon connue en soi. En outre, on peut prévoir dans l'enveloppe intérieure 30 un clapet anti-surpression (non représenté) afin d'éviter de faire éclater accidentellement la membrane 30.  As best seen in Figures 3 and 4, the inner volume 22 communicates with the outside by a sealed cap, for example of the type of inflation nozzle used in the aforementioned field of pneumatic articles, the plug 40 being preferably located within one of the regions R1 and R2 so as to simultaneously cross the material thickness of the outer casing 10 and the material thickness of the inner casing 30. This cap allows to apply an air pressure or another gas, adjustable within the interior volume 22, and virtually empty this interior volume. The stopper 40 advantageously comprises a non-return valve, in a manner known per se. In addition, it is possible to provide in the inner casing 30 a pressure relief valve (not shown) in order to avoid accidentally bursting the membrane 30.
Le volume extérieur 21 communique avec l'extérieur par au moins un bouchon, de préférence un bouchon à vis étanche 50 de section typiquement comprise entre 10 et 30 cm2, doté d'une grille 51 dont la taille des ouvertures est dimensionnée pour éviter la sortie des particules, à des fins expliquées plus loin. Ce bouchon est de préférence situé dans la zone de dos 105 du siège de façon à ne pas gêner le confort. The external volume 21 communicates with the outside by at least one plug, preferably a leakproof screw plug 50 of section typically between 10 and 30 cm 2 , provided with a gate 51 whose size openings is sized to avoid the particle release, for purposes explained below. This cap is preferably located in the back area 105 of the seat so as not to hinder comfort.
Dans une forme de réalisation préférée, et comme on le verra plus loin en référence à la figure 4, on prévoit deux bouchons, tous deux situés dans la zone de dos 105 pour ne pas gêner le confort.  In a preferred embodiment, and as will be seen below with reference to Figure 4, there are two plugs, both located in the back area 105 to not interfere with comfort.
Pour réaliser le siège, on fabrique une structure telle que représentée sur les figures 1 et 2, on remplit le volume extérieur 21 avec un matériau de remplissage, soit à travers l'ouverture du bouchon 50, soit avant de refermer l'enveloppe 10 (par exemple par couture). To make the seat, a structure is produced as shown in FIGS. 1 and 2, the external volume 21 is filled with a material of filling, either through the opening of the stopper 50, or before closing the casing 10 (for example by sewing).
Dans une forme de réalisation préférée, le matériau de remplissage est un matériau particulaire, et les particules comprennent un mélange (de préférence à 50/50 environ) de copeaux de mousse par exemple de polyester et de fibres par exemple de polyester. La taille moyenne des particules est de préférence comprise entre 5 et 30 mm. Alternativement à l'un ou l'autre de ces types de particules ou en complément, on peut prévoir des microbilles de polystyrène expansé. Un tel mélange permet à la fois de garantir un excellent confort et d'assurer que la mobilité des particules dans le second volume ne soit ni trop importante (une zone risquant de se trouver entièrement dépourvue de particules), ni trop faible (la caractéristique de variabilité de forme, en fonction notamment de la posture du sujet, étant importante notamment dans le cas de grands coussins ou sièges de terrasse ou de piscine).  In a preferred embodiment, the filler material is a particulate material, and the particles comprise a mixture (preferably about 50/50) of foam chips for example of polyester and fibers such as polyester. The average size of the particles is preferably between 5 and 30 mm. Alternatively to one or other of these types of particles or in addition, one can provide expanded polystyrene microbeads. Such a mixture makes it possible at the same time to guarantee an excellent comfort and to ensure that the mobility of the particles in the second volume is neither too important (an area likely to be entirely devoid of particles), nor too weak (the characteristic of shape variability, depending in particular on the posture of the subject, being important especially in the case of large cushions or terrace or pool seats).
Dans le cas où le matériau de remplissage est particulaire (copeaux de mousse, fibres, microbilles, etc.) le remplissage s'effectue de préférence par injection dans un flux d'air ou autre gaz. Dans ce cas, le matériau de l'enveloppe extérieure 10 est par exemple un matériau tissé ou non tissé laissant facilement passer l'air, mais dont les ouvertures sont beaucoup plus petites sur la taille des particules du matériau de remplissage.  In the case where the filling material is particulate (foam chips, fibers, microbeads, etc.) the filling is preferably performed by injection into a stream of air or other gas. In this case, the material of the outer casing 10 is for example a woven or non-woven material easily passing air, but whose openings are much smaller on the size of the particles of the filling material.
Comme mentionné plus haut et illustré sur la figure 4, on peut prévoir que l'enveloppe extérieure 10 soit dotée de deux bouchons, avec un bouchon 45 de remplissage à la fabrication, présentant un passage dégagé et suffisamment grand (typiquement autour de 10 à 30 cm2) pour injecter les particules dans un flux d'air, et l'autre 50 éventuellement avec un passage de section plus petite, comportant une grille 51 comme précité avec des ouvertures permettant la sortie de l'air injecté tout en empêchant la sortie des particules introduites. Les bouchons 45 et 50 sont de préférence des bouchons à vis, et le bouchon 45 est doté d'un clapet anti-retour évitant tout risque de sortie du matériau de remplissage lorsque le bouchon est dévissé. Ensuite, le bouchon 50 ou les bouchons 45 et 50 étant fermé(s), le volume intérieur 22 est rempli avec de l'air, à l'aide d'un embout de remplissage (non représenté) raccordé de façon étanche au bouchon 40. Ceci peut être effectué soit avec la bouche, soit avec un gonfleur manuel ou motorisé. As mentioned above and illustrated in FIG. 4, provision can be made for the outer casing 10 to be provided with two plugs, with a plug 45 for filling during manufacture, having a clear and sufficiently large passage (typically around 10 to 30 cm). cm 2 ) for injecting the particles into an air flow, and the other 50 possibly with a passage of smaller section, having a grid 51 as mentioned above with openings allowing the exit of the injected air while preventing the exit introduced particles. The plugs 45 and 50 are preferably screw plugs, and the plug 45 is provided with a non-return valve avoiding any risk of exit of the filling material when the plug is unscrewed. Then, the plug 50 or plugs 45 and 50 being closed (s), the internal volume 22 is filled with air, using a filling tip (not shown) sealingly connected to the plug 40 This can be done either with the mouth or with a manual or motorized inflator.
La pression de gonflage détermine la rigidité et le « moelleux », et peut être ajustée à toute valeur souhaitée sans excéder une certaine limite.  The inflation pressure determines rigidity and "softness", and can be adjusted to any desired value without exceeding a certain limit.
Une fois ces opérations achevées et les bouchons fermés, on place de préférence l'ensemble dans une housse ou enveloppe d'habillage en matériau et de couleur choisis (typiquement une toile épaisse en toile de polyamide ou de polyester, en cuir, etc.) et le siège est prêt à être utilisé.  Once these operations have been completed and the caps closed, the set is preferably placed in a cover or casing made of selected material and color (typically a thick canvas of polyamide or polyester, leather, etc.). and the seat is ready to use.
On comprend que grâce au fait qu'une proportion substantielle de l'espace intérieur du siège est remplie d'air ou d'un autre gaz, le poids du siège est sensiblement réduit, alors même qu'il conserve des qualités comparables, voire supérieures (rigidité ajustable) à celles d'un siège entièrement rempli de matériau particulaire.  It will be understood that because a substantial proportion of the interior space of the seat is filled with air or another gas, the weight of the seat is substantially reduced, even though it retains comparable or even better qualities. (adjustable rigidity) to those of a seat fully filled with particulate material.
Pour le transport du siège, soit lors de la commercialisation, soit après achat, on vide le volume intérieur 22 de son air, soit en pressant sur le siège après avoir ouvert le bouchon 40, soit en connectant une pompe à vide, puis on referme de préférence le bouchon pour éviter une nouvelle entrée d'air. Ceci permet une diminution de volume du siège correspondant sensiblement au volume intérieur 22. Typiquement, selon la configuration et le volume de l'espace intérieur et de l'espace extérieur, on peut atteindre une réduction de volume de 25 à 50 %, typiquement d'environ 35 %.  For the transport of the seat, either during the marketing or after purchase, the internal volume 22 of its air is emptied, either by pressing on the seat after opening the cap 40, or by connecting a vacuum pump, then closing preferably the plug to prevent a new air intake. This allows a decrease in seat volume corresponding substantially to the internal volume 22. Typically, depending on the configuration and the volume of the interior space and the outside space, a volume reduction of 25 to 50%, typically about 35%.
On peut aussi, dans le cas où le matériau de remplissage est un matériau particulaire, appliquer du vide au volume extérieur 21 de manière à réduire encore le volume du siège pour son transport. Dans ce cas, la grille prévue dans le bouchon 50 permet d'appliquer une pompe à vide sans risquer de retirer du matériau de remplissage.  It is also possible, in the case where the filling material is a particulate material, to apply a vacuum to the external volume 21 so as to further reduce the volume of the seat for transport. In this case, the grid provided in the plug 50 makes it possible to apply a vacuum pump without the risk of removing filler material.
On aboutit en ce faisant à un gain de volume complémentaire qui peut être de 5 à 15 % du volume total en utilisation, selon notamment le type de particule et la densité avec laquelle elles ont été placées dans le volume extérieur. This results in a complementary volume gain which can be 5 to 15% of the total volume in use, depending in particular on the type of particle and the density with which they were placed in the outer volume.
Après livraison, on réinjecte de l'air dans le volume intérieur 22 et le cas échéant dans le volume extérieur, et l'élément de mobilier peut être utilisé après avoir mis ou remis la housse en place.  After delivery, air is re-injected into the interior volume 22 and, where appropriate, into the exterior volume, and the furniture element can be used after putting on or replacing the cover.
On notera que le fait que l'enveloppe extérieure 10 et l'enveloppe intérieure 30 sont reliées l'une à l'autre au niveau d'un nombre limité de régions de liaison permet de garder une liberté de forme importante, le matériau situé dans le volume extérieur 21 pouvant se déplacer (de façon plus ou moins spontanée selon la nature du matériau) en fonction des différentes contraintes (gravité, pression exercée par l'utilisateur).  It should be noted that the fact that the outer envelope 10 and the inner envelope 30 are connected to each other at a limited number of bonding regions makes it possible to retain considerable freedom of shape, the material located in the external volume 21 can move (more or less spontaneously depending on the nature of the material) depending on the various constraints (gravity, pressure exerted by the user).

- dans les régions de liaison entre l'enveloppe intérieure 30 et l'enveloppe extérieure 10, cette liaison peut éventuellement être séparable (Velcro®, etc.).  in the connection regions between the inner envelope 30 and the outer envelope 10, this connection may optionally be separable (Velcro®, etc.).
L'invention s'applique notamment à des éléments de type sièges ou coussins de grand volume (typiquement de 0,2 à 1 m2) pour l'extérieur (terrasses, piscines). The invention is particularly applicable to elements of the type seats or cushions of large volume (typically 0.2 to 1 m 2 ) for outdoor (terraces, swimming pools).
