The deformable element is composed of a slip cover (52) receiving balls e.g. alveolar balls, where the cover has a shape complementary to a shape of the cavity for integrating a surface (53) of the cover in the shell. The shell and the balls are made of expanded polystyrene/polypropylene.

Description

Domaine de l'inventionField of the invention

La présente invention concerne un meuble tel qu'un fauteuil, tabouret, pouf ou siège pour enfant, table à langer, c'est-à-dire un support formant éventuellement un piétement et une surface d'appui souple.The present invention relates to a piece of furniture such as an armchair, stool, pouf or child seat, changing table, that is to say a support possibly forming a base and a flexible support surface.

Etat de la techniqueState of the art

Il existe une très grande diversité de sièges de structure traditionnelle, ayant un piétement et une surface d'appui formant assise, complétés le cas échéant par un dossier. Des formes modernes de siège utilisant les caractéristiques des matériaux récents, notamment des matières plastiques, ont connu un certain développement tels que des sièges gonflables, notamment utilisés en extérieur ou encore des sièges constitués par une housse contenant des billes de polystyrène, de la mousse ou de l'ouate, l'ensemble constituant un siège déformable sans forme bien définie et qui peut servir de siège bas, de tabouret, de fauteuil suivant la forme et l'empreinte que l'utilisateur lui donne.There is a great diversity of traditional structure seats, having a base and a seating surface, supplemented if necessary by a folder. Modern forms of seat using the characteristics of recent materials, including plastics, have experienced some development such as inflatable seats, especially used outdoors or seats consisting of a cover containing polystyrene beads, foam or cotton wool, the assembly constituting a deformable seat without a well-defined shape and which can serve as a low seat, stool, chair depending on the shape and the footprint that the user gives it.

Ces sièges de type pouf sont appréciés pour leur confort et leur souplesse grâce à la fluidité et à la malléabilité du volume constitué par cette housse. Ils s'adaptent naturellement aux formes grâce aux billes de PSE (polystyrène expansé) qui se déplacent dans la housse avec pour conséquence une répartition des pressions, épousant les formes du corps en contact avec le pouf. Ces poufs ont souvent la forme de cylindre, de poire ou d'une sorte de couette.These ottoman type seats are appreciated for their comfort and flexibility thanks to the fluidity and malleability of the volume constituted by this cover. They adapt naturally to the shapes thanks to the EPS balls (expanded polystyrene) which move in the cover with the consequence of a distribution of the pressures, marrying the shapes of the body in contact with the pouf. These poufs often have the shape of cylinder, pear or a kind of duvet.

Mais ces sièges ont l'inconvénient de ne pas avoir une forme générale et de ne constituer qu'un type de siège pour un usage relativement limité et d'un aspect assez uniforme, modifiable seulement par la couleur et la matière de la housse. De plus la surface par laquelle ce pouf s'appuie sur le sol est n'importe quelle surface du pouf puisque l'ensemble est déformable et malléable, si bien qu'on utilisera comme surface d'appui, pratiquement celle qui se présente à l'utilisateur.But these seats have the disadvantage of not having a general shape and to constitute a type of seat for a relatively limited use and a fairly uniform appearance, modifiable only by the color and material of the cover. Moreover the surface by which this pouf leans on the ground is any surface of the pouf since the assembly is deformable and malleable, so that one will use as surface of support, practically that which is presented to the 'user.

Un tel siège ne peut être utilisé que sur une surface propre. La surface peut certes être irrégulière puisque l'irrégularité est absorbée par la déformation du siège.Such a seat can only be used on a clean surface. The surface can certainly be irregular since the irregularity is absorbed by the deformation of the seat.

En outre le siège bien que très confortable car offrant une très grande surface d'appui pour le corps du fait de sa déformation, a l'inconvénient de donner un sentiment d'instabilité puisque sa forme n'est pas tenue et les billes qui le remplissent peuvent couler sous l'effet d'une augmentation de pression locale.In addition the seat although very comfortable because offering a very large support surface for the body due to its deformation, has the disadvantage of giving a feeling of instability since its shape is not held and the balls that the fill may leak due to local pressure increase.

Les possibilités de rangement de ce siège sont également peu satisfaisantes.The storage possibilities of this seat are also unsatisfactory.

But de l'inventionPurpose of the invention

La présente invention a pour but de développer un type de meuble tel qu'un siège ou meuble de ce type, qui soit confortable, offre une bonne tenue de la forme, permette un rangement tout en étant léger, souple et malléable.The present invention aims to develop a type of furniture such as a seat or furniture of this type, which is comfortable, offers good shape, allows storage while being light, flexible and malleable.

Exposé et avantages de l'inventionDescription and advantages of the invention

A cet effet, la présente invention concerne un meuble du type défini ci-dessus caractérisé en ce qu'il comprend une coque ayant d'un côté, une surface d'appui et de l'autre, une cavité munie au moins en partie d'un bord recevant un élément déformable,

  • l'élément déformable destiné à être calé dans la cavité de la coque forme une surface de réception déformable et cet élément est composé d'une housse recevant une charge de produits en grains, notamment de billes pleines ou alvéolaires de PSE (polystyrène expansé), PPE (polypropylène expansé),
  • la housse ayant pour sa partie venant dans la coque, une forme complémentaire de celle de la cavité.
To this end, the present invention relates to a piece of furniture of the type defined above characterized in that it comprises a shell having on one side, a bearing surface and on the other, a cavity provided at least partly with an edge receiving a deformable element,
  • the deformable element intended to be wedged in the cavity of the shell forms a deformable receiving surface and this element is composed of a cover receiving a load of granular products, in particular solid or foamed balls of EPS (expanded polystyrene), EPP (expanded polypropylene),
  • the cover having for its part coming into the shell, a shape complementary to that of the cavity.

Ce meuble, notamment utilisé comme siège, table à langer ou application similaire, a l'avantage d'assurer un très grand confort pour la surface d'appui puisque la surface d'appui épouse la forme de la partie corps qui s'appuie sur elle, tout en ne pouvant pas s'échapper trop librement comme cela est le cas des poufs chargés de billes de PSE, qui peuvent être en mouvement perpétuel, sous l'effet de la moindre poussée locale contre la housse. Le meuble ainsi réalisé conserve sa forme et son aspect grâce à la coque retenant l'élément déformable tant pendant l'utilisation que pendant les phases de non-utilisation. Sur un plan très pratique, comme la coque s'appuie sur le sol, et que celle-ci est rigide et que la surface de l'élément déformable qui constitue la surface de réception ou surface d'appui n'est pas n'importe quelle surface de l'élément déformable, les problèmes d'entretien et de salissure de l'élément déformable ne se posent pas différemment des problèmes de nettoyage d'un siège classique puisque la surface par laquelle le meuble s'appuie sur le sol est le dessous de la coque. De tels meubles peuvent également servir de meubles de jardin ou de piscine tout en conservant leur qualité de confort, d'esthétique, de facilité d'entretien.This furniture, used in particular as a seat, changing table or similar application, has the advantage of ensuring a very high comfort for the support surface since the bearing surface matches the shape of the body part which is based on it, while not being able to escape too freely as it is the case of the poufs loaded with balls of PSE, which can be in perpetual movement, under the effect of the smallest local push against the cover. The furniture thus produced retains its shape and appearance thanks to the shell holding the deformable element both during use and during the phases of non-use. On a very practical level, as the shell rests on the ground, and that it is rigid and that the surface of the deformable element which constitutes the receiving surface or support surface is not any matter which surface of the deformable element, the problems of maintenance and soiling of the deformable element do not arise differently from the problems of cleaning a conventional seat since the surface by which the piece of furniture rests on the ground is the below the hull. Such furniture can also be used as garden furniture or pool while maintaining their quality of comfort, aesthetics, ease of maintenance.

Le rangement d'un tel meuble est facilité car l'élément déformable peut s'enlever, si nécessaire, les coques peuvent être empilées et les éléments déformables également empilés en position de rangement.The storage of such a piece of furniture is facilitated because the deformable element can be removed, if necessary, the shells can be stacked and deformable elements also stacked in the storage position.

La recombinaison des meubles est facile.The recombination of furniture is easy.

Le caractère amovible de l'élément déformable par rapport à la coque permet non seulement le nettoyage facile et séparé de la coque et de l'élément déformable, mais également des combinaisons de couleurs et de matières tant par la matière et l'aspect de la coque que la matière et l'aspect, voire la forme de l'élément déformable. Cette interchangeabilité et combinaisons des éléments déformables et des coques permettent de modifier les combinaisons de couleurs et de matières des différents sièges.The removable nature of the deformable element relative to the shell allows not only easy and separate cleaning of the shell and the deformable element, but also combinations of colors and materials both by the material and the appearance of the shell that the material and the appearance, or even the shape of the deformable element. This interchangeability and combinations of the deformable elements and shells allow to change the combinations of colors and materials of the various seats.

Cet élément déformable est parfaitement tenu dans la coque par sa partie en quelque sorte préformée sans que cela ne soit au détriment de la souplesse et de la malléabilité de l'élément déformable une fois placé dans la coque. Cette préforme donnée à la partie de la housse de l'élément déformable se logeant dans la cavité de la coque a l'avantage de permettre à l'élément préformable d'épouser parfaitement la cavité et de se retenir dans celle-ci par une liaison par la forme, bien que l'élément déformable soit et reste parfaitement souple et malléable. La préforme de la housse peut se réaliser par un moyen technique, par une forme ou des plis donnés à la housse ou encore par le mode d'assemblage de la housse pour arriver à cette forme complémentaire à celle de la cavité.This deformable element is perfectly held in the shell by its somewhat preformed part without this being to the detriment of the flexibility and malleability of the deformable element once placed in the shell. This preform given to the portion of the cover of the deformable element housed in the cavity of the shell has the advantage of allowing the preformable element to perfectly fit the cavity and to be retained therein by a connection by the form, although the deformable element is and remains perfectly flexible and malleable. The preform of the cover can be achieved by a technical means, by a shape or folds given to the cover or by the method of assembly of the cover to arrive at this shape complementary to that of the cavity.

L'élément déformable étant avant tout un élément souple, la forme complémentaire de sa partie venant dans la cavité et la forme de la cavité doivent être de préférence adaptées sans que cela ne nécessite un assemblage de haute précision.The deformable element being above all a flexible element, the complementary shape of its portion coming into the cavity and the shape of the cavity must preferably be adapted without this requiring a high precision assembly.

La liaison peut être complétée par des moyens d'assemblage tels que des bandes à griffes, des rubans adhésifs double face ou autres qui permettent de compléter le blocage de l'élément déformable dans la cavité de la coque sans pour autant limiter les possibilités d'enlèvement et le cas échéant de remplacement.The connection can be completed by means of assembly such as claw strips, double-sided adhesive tapes or others which make it possible to complete the locking of the deformable element in the cavity of the shell without limiting the possibilities of removal and if necessary replacement.

Le siège selon l'invention est très léger puisque la coque peut être en matière plastique expansée, en matière plastique moulée, creuse ou pleine, ou encore en matière plastique injectée. La coque peut également être réalisée, si elle est creuse, par rotomoulage ou extrusion-soufflage.The seat according to the invention is very light since the shell may be expanded plastic, molded plastic, hollow or solid, or plastic injected. The hull can also be made, if it is hollow, by rotational molding or extrusion blow molding.

Enfin, l'ensemble tant pour la coque que l'élément déformable conserve une certaine souplesse, absorbant les chocs et les vibrations.Finally, all for both the hull and the deformable element retains a certain flexibility, absorbing shocks and vibrations.

La fabrication du meuble est très simple comme cela a été indiqué ci-dessus. Le stockage est tout aussi facile et peut être fait séparément pour la coque et l'élément déformable.The manufacture of furniture is very simple as has been indicated above. The storage is just as easy and can be done separately for the hull and the deformable element.

Suivant une autre caractéristique avantageuse, la coque a une forme de tronc de cône ou de tronc de pyramide de section circulaire, carré ou rectangulaire ou une forme prismatique, avec des bords relevés, recevant un élément déformable de dimensions dépassant nettement de la cavité pour former un siège de type tabouret ou pouf.According to another advantageous characteristic, the shell has a truncated cone or truncated pyramid shape of circular, square or rectangular section or a prismatic shape, with raised edges, receiving a deformable element of dimensions clearly exceeding the cavity to form a stool or ottoman type seat.

Cette forme très simple de la coque peut être le cas échéant adaptée dans sa forme extérieure et celle de la cavité pour faciliter l'empilage des coques.This very simple form of the shell may be adapted if necessary in its outer shape and that of the cavity to facilitate the stacking of the shells.

Suivant une autre caractéristique avantageuse, la coque a une forme allongée, relativement plate, bordée sur au moins trois côtés d'un bord et recevant un élément déformable, relativement plat, de manière à former un matelas à langer. Le dessous peut également avoir des bossages ou des protubérances constituant des butées qui permettent de caler le matelas à langer sur le rebord d'une baignoire ou sur les côtés d'un lit à barreaux..According to another advantageous characteristic, the shell has an elongated shape, relatively flat, bordered on at least three sides of an edge and receiving a deformable element, relatively flat, so as to form a changing mat. The underside may also have bosses or protuberances constituting stops that allow to wedge the changing mat on the edge of a bath or on the sides of a crib.

Suivant une autre caractéristique avantageuse, la coque se compose d'une partie formant assise avec une cavité se poursuivant par une partie montante, sur l'un des côtés de la partie, en étant bordée par le prolongement du bord de la cavité pour former un rebord côté intérieur, et l'élément déformable est une pièce allongée occupant à la fois la cavité de la partie inférieure et une partie de la surface de la partie relevée de façon à constituer un fauteuil.According to another advantageous characteristic, the shell consists of a portion forming a seat with a cavity continuing with a rising portion, on one of the sides of the part, being bordered by the extension of the edge of the cavity to form a flange on the inner side, and the deformable element is an elongated piece occupying both the cavity of the lower part and a part of the surface of the raised part so as to constitute an armchair.

Suivant une autre caractéristique avantageuse et comme déjà évoqué ci-dessus, la partie de la coque correspondant à l'assise du fauteuil comporte une cavité fermée sur quatre côtés et l'élément déformable a une partie inférieure de forme correspondant à cette cavité de l'assise pour s'y encastrer.According to another advantageous characteristic and as already mentioned above, the portion of the shell corresponding to the seat of the chair has a cavity closed on four sides and the deformable element has a lower portion of shape corresponding to this cavity of the sitting to fit in.

On facilite également la tenue du meuble sur des surfaces irrégulières, par exemple en extérieur, si le dessous de la coque a une partie en creux délimitant la surface d'appui qui peut être interrompue ou être continue tout autour de la partie en creux.It also facilitates the holding of the furniture on irregular surfaces, for example outside, if the underside of the shell has a recessed portion defining the bearing surface which can be interrupted or be continuous all around the recessed portion.

Suivant une autre caractéristique avantageuse, l'élément déformable est subdivisé par des cloisons internes pour former des volumes retenant les produits en grains ou en billes dans chacun des volumes.According to another advantageous characteristic, the deformable element is subdivided by internal partitions to form volumes retaining the products in grains or balls in each of the volumes.

Selon une autre variante de réalisation, la coque est un cylindre droit dont la paroi périphérique comporte, sur sa face intérieure, des groupes de butées à différentes hauteurs dans le cylindre, ainsi qu'un fond amovible de section correspondant à l'espace libre de la section du cylindre formé par la paroi périphérique de la coque, ce fond étant muni d'au moins un groupe de contre-butées pour venir s'appuyer sur l'un ou l'autre groupe de butée et définir la profondeur de la cavité dans le cylindre ouvert en haut et recevant l'élément déformable.According to another variant embodiment, the shell is a straight cylinder whose peripheral wall comprises, on its inner face, groups of stops at different heights in the cylinder, as well as a removable bottom section corresponding to the free space of the section of the cylinder formed by the peripheral wall of the shell, this bottom being provided with at least one group of counterbeats to come abut one or the other abutment group and define the depth of the cavity in the cylinder open at the top and receiving the deformable element.

En particulier, le cylindre droit a une section ayant au moins un axe de symétrie ou une symétrie de rotation par rapport au centre de la section.In particular, the right cylinder has a section having at least one axis of symmetry or rotational symmetry with respect to the center of the section.

Ce siège en forme de tabouret peut recevoir un élément amovible déformable de consistance et de volume différent suivant le réglage en hauteur du fond amovible ce qui permet de modifier ou d'adapter la souplesse ou la déformabilité de la surface d'assise du siège.This stool-shaped seat can receive a deformable removable element of different consistency and volume depending on the height adjustment of the removable bottom which allows to modify or adapt the flexibility or deformability of the seating surface of the seat.

Suivant une autre caractéristique avantageuse, les produits en grains, notamment des billes, sont des billes creuses ou pleines en polystyrène expansé ou en polypropylène expansé.According to another advantageous characteristic, the granular products, in particular beads, are hollow or solid beads made of expanded polystyrene or expanded polypropylene.

Suivant une autre caractéristique avantageuse, la coque est réalisée en polystyrène expansé (PSE), polypropylène expansé (PPE), réalisée par injection, rotomoulage, extrusion, soufflage.According to another advantageous characteristic, the shell is made of expanded polystyrene (EPS), expanded polypropylene (EPP), produced by injection, rotational molding, extrusion, blowing.

Suivant une autre caractéristique avantageuse, la coque est réalisée en revêtement floqué.According to another advantageous characteristic, the shell is made of flocked coating.

Description de modes de réalisationDescription of embodiments

Selon les figures 1, 2 et 3, l'invention concerne un meuble 100 de type siège représenté dans sa forme la plus générale et la plus simple aux figures 1, 2.According to Figures 1, 2 and 3 the invention relates to a seat type furniture 100 represented in its most general and simplest form to Figures 1, 2 .

Ce meuble 100 se compose d'une partie 10 relativement rigide en forme de coque ayant une surface d'appui 11 par laquelle la coque repose sur le sol ou autre support suivant la nature du meuble réalisé, par exemple un lite, une commode, une table, par exemple dans le cas d'un matelas à langer.. Cette surface d'appui 11 peut être continue ou constituée par des plots ou des parties en relief au nombre d'au moins trois, définissant la surface d'appui ou le polygone de sustentation.This piece of furniture 100 consists of a relatively rigid portion 10 in the form of a shell having a bearing surface 11 through which the shell rests on the floor or other support depending on the nature of the piece of furniture made, for example a bed, a dresser, a table, for example in the case of a changing mat .. This bearing surface 11 may be continuous or constituted by studs or raised portions of at least three, defining the support surface or the polygon of levitation.

La face inférieure de la coque 10 peut former une surface d'appui 11 interrompue, par exemple périphérique avec des plots comme indiqué ci-dessus et la partie intérieure avoir une forme en retrait représentée par le tracé en trait interrompu 15, de façon que toute la surface inférieure de la coque 10 n'appuie pas sur le sol et qu'ainsi on puisse absorber les éventuelles irrégularités et stabiliser l'appui.The lower face of the shell 10 may form an abutment surface 11 interrupted, for example peripheral with pads as indicated above and the inner part have a recessed shape represented by the broken line 15, so that any the lower surface of the hull 10 does not rest on the ground and thus we can absorb any irregularities and stabilize the support.

La coque 10 a une partie intérieure formant une cavité 12, ouverte vers le dessus pour recevoir un élément déformable 50 formant la surface de réception. En fonction de la forme du meuble, la cavité 12 est entourée d'une paroi 121, périphérique, s'étendant de façon continue tout autour de la cavité 12. Cette paroi délimitant la cavité peut également être interrompue ou n'être prévue que sur un certain nombre de côtés bordant la cavité et assurant le maintien de l'élément déformable 50. Cette variante est envisageable pour les différentes formes de réalisation de la coque.The shell 10 has an interior portion forming a cavity 12, open towards the top to receive a deformable element 50 forming the receiving surface. Depending on the shape of the piece of furniture, the cavity 12 is surrounded by a peripheral wall 121 extending continuously all around the cavity 12. This wall delimiting the cavity may also be interrupted or only provided on a number of sides bordering the cavity and ensuring the maintenance of the deformable element 50. This variant can be envisaged for the different embodiments of the hull.

L'élément déformable 50 est destiné à être calé dans la cavité et de préférence déborder de la cavité 12 ou de ses parois 121.The deformable element 50 is intended to be wedged in the cavity and preferably to protrude from the cavity 12 or its walls 121.

L'élément déformable 50 forme la surface de réception 51 du meuble c'est-à-dire l'assise ou la surface sur laquelle on peut s'appuyer. Cette surface de réception 51 est déformable.The deformable element 50 forms the receiving surface 51 of the furniture that is to say the seat or the surface on which one can rely. This receiving surface 51 is deformable.

L'élément déformable 50, malléable, est composé d'une housse 52 apparaissant seule et contenant une charge non référencée de produits en grains, c'est-à-dire susceptible de couler. Ces produits en grains sont notamment des billes de PSE (polystyrène expansé), en PPE (polypropylène expansé). Les billes peuvent être alvéolaires, creuses ou pleines.The deformable element 50, malleable, consists of a cover 52 appearing alone and containing a non-referenced load of granular products, that is to say likely to flow. These granular products include beads EPS (expanded polystyrene), EPP (expanded polypropylene). The beads may be alveolar, hollow or solid.

Sur sa partie venant dans la cavité 12 de la coque 10 la housse 52 a une surface 53 de forme complémentaire à celle de la cavité 12 pour s'intégrer facilement dans la cavité et se retenir dans celle-ci par une liaison par la forme. La surface 53 fait partie de l'enveloppe et elle est mise en forme pour correspondre à celle de la cavité, pour s'y adapter parfaitement tout en restant souple et malléable.On its part coming into the cavity 12 of the shell 10 the cover 52 has a surface 53 of complementary shape to that of the cavity 12 to easily integrate into the cavity and to be retained therein by a connection by the shape. The surface 53 is part of the envelope and is shaped to match that of the cavity, to fit perfectly while remaining flexible and malleable.

Cette liaison par la forme peut être complétée par des moyens de liaison 54 prévus sur la face inférieure et éventuellement les côtés 53 de la housse 52 pour coopérer avec des éléments complémentaires 14 au fond ou sur les côtés de la cavité 12 de la coque 10.This connection by the shape can be completed by connecting means 54 provided on the lower face and possibly the sides 53 of the cover 52 to cooperate with complementary elements 14 at the bottom or on the sides of the cavity 12 of the shell 10.

Les éléments de liaison 14, 54 peuvent être des surfaces d'accrochage à minigriffes, des surfaces adhésives telles tel qu'un adhésif double face, pour retenir de manière amovible l'élément déformable 50 dans la cavité 12 tout en permettant de l'en extraire pour le remplacer, le nettoyer ou pour le ranger séparément de la coque 10. Selon une variante non représentée, les bandes de fixation peuvent traverser la coque et être fixées ou nouées sous le dessous de la coque.The connecting elements 14, 54 may be minigriff hooking surfaces, adhesive surfaces such as a double-sided adhesive, for removably retaining the deformable element 50 in the cavity 12 while allowing the extract to replace it, clean it or store it separately from the hull 10. According to a variant not shown, the fastening strips can pass through the hull and be fixed or knotted under the underside of the hull.

La coque 10 est de préférence réalisée en une matière expansée ; elle peut également être réalisée en matière plastique moulée par exemple par rotomoulage, ou par injection.The shell 10 is preferably made of an expanded material; it can also be made of plastic molded for example by rotational molding, or by injection.

La coque 10 et l'élément de meuble 100 ainsi réalisés, représentés aux figures 1, 2 ont une forme en tronc de pyramide avec une cavité 12 également en forme de tronc de pyramide mais inversée.The shell 10 and the furniture element 100 thus produced, represented in FIGS. Figures 1, 2 have a truncated pyramid shape with a cavity 12 also shaped pyramid trunk but inverted.

De manière générale cette forme peut être une forme conique ou cylindrique ou prismatique, de section relativement quelconque, par exemple circulaire, elliptique, carrée ou rectangulaire.In general, this shape may be a conical or cylindrical or prismatic shape, of relatively arbitrary cross section, for example circular, elliptical, square or rectangular.

Le meuble 100 présenté aux figures 1, 2 est un exemple de siège bas tel qu'un tabouret.Furniture 100 presented to Figures 1, 2 is an example of a low seat such as a stool.

Ce meuble peut également avoir une forme plus haute, par exemple comme le meuble 200 représenté à la figure 3 qui est un siège de type tabouret ou pouf dont la coque 210 est relativement haute de forme cylindrique ou tronconique et une cavité 212 elle-même cylindrique ou tronconique, bordée par la paroi 221This piece of furniture can also have a higher shape, for example as the piece of furniture 200 represented in FIG. figure 3 which is a seat of stool or pouf type whose hull 210 is relatively high cylindrical or frustoconical and a cavity 212 itself cylindrical or frustoconical, bordered by the wall 221

L'élément déformable 250 destiné à se loger dans la cavité 212 de la coque 210 représentée en coupe a une forme complémentaire à celle de la cavité pour la partie inférieure 253 de la housse 252.The deformable element 250 intended to be housed in the cavity 212 of the shell 210 shown in section has a shape complementary to that of the cavity for the lower part 253 of the cover 252.

Le volume de l'élément déformable 250 est tel que le dessus 251 dépasse largement du bord supérieur de la coque de façon que pratiquement seul l'élément déformable constitue la surface d'assise ou la surface formant repose-pied, offrant une possibilité de déformation assez importante tout en étant tenu parfaitement par la coque 210.The volume of the deformable member 250 is such that the top 251 greatly exceeds the upper edge of the shell so that substantially only the deformable member constitutes the seating surface or the footrest surface, providing a possibility of deformation quite important while being held perfectly by the hull 210.

Dans les modes de réalisation de l'invention, la coque 10, 210 assure la stabilité de forme au meuble et une très grande capacité de déformation pour l'élément déformable et malléable 50, 250 puisque l'ensemble du volume de l'élément déformable, c'est-à-dire la charge pulvérulente ou fluide, contenue dans la housse peut se déformer pour prendre l'empreinte de la surface qui repose sur l'élément déformable.In the embodiments of the invention, the shell 10, 210 ensures the stability of form to the furniture and a very high capacity of deformation for the deformable and malleable element 50, 250 since the entire volume of the deformable element that is to say, the powdery or fluid charge, contained in the cover can be deformed to take the impression of the surface that rests on the deformable element.

La figure 4 montre un meuble constituant un matelas à langer 300. La coque 310 est une pièce de forme relativement allongée, avec une extrémité 316 arrondie et l'autre droite ; la cavité 312 est délimitée par un bord 3121 s'étendant sur trois côtés, le bord étant enlevé sur le quatrième côté, avant. La coque 310 a de préférence une structure assez rigide ce qui permet de la placer non seulement sur une table mais également sur une surface avec des parties en creux, par exemple sur le dessus d'un lavabo ou en travers d'une baignoire pour bébé. L'élément déformable 350 est de forme allongée, placé dans la cavité 312 de la coque 310.The figure 4 shows a piece of furniture constituting a changing mat 300. The shell 310 is a relatively elongated piece, with one end 316 rounded and the other right; the cavity 312 is delimited by an edge 3121 extending on three sides, the edge being removed on the fourth side, front. The shell 310 preferably has a fairly rigid structure which allows to place not only on a table but also on a surface with recessed portions, for example on the top of a sink or across a baby bath . The deformable element 350 is of elongate shape, placed in the cavity 312 of the shell 310.

L'élément déformable est de préférence contenu entre les bords de la coque qui constituent une retenue latérale de l'enfant plus de sa forme en empreinte dans l'élément déformable.The deformable element is preferably contained between the edges of the shell which constitute a lateral retention of the child more than its imprinted shape in the deformable element.

Le dessous de la coque peut comporter des éléments en relief pour favoriser sa tenue sur le rebord d'une baignoire, les côtés d'un lit à barreaux, etc sur lesquels peut se poser le matelas à langer.The underside of the shell may comprise elements in relief to promote its holding on the edge of a bath, the sides of a crib, etc. on which the changing mat can be placed.

Dans cet exemple d'application, la déformabilité de l'élément 350 qui forme une empreinte figée, a l'avantage de retenir l'enfant en place et de lui éviter de glisser par rapport au matelas à langer.In this example of application, the deformability of the element 350 which forms a fixed impression, has the advantage of holding the child in place and prevent him from sliding relative to the changing mat.

Le dessous de la coque peut comporter des éléments en relief pour favoriser sa tenue sur le rebord d'une baignoire, les côtés d'un lit à barreaux, etc sur lesquels peut se poser le matelas à langer.The underside of the shell may comprise elements in relief to promote its holding on the edge of a bath, the sides of a crib, etc. on which the changing mat can be placed.

La figure 5 montre un fauteuil 400 ou siège également avec une coque 410 ayant une assise 420 et un dossier 430 incliné et un élément déformable 450 placé dans la cavité de l'assise 420 et du dossier 430.The figure 5 shows a chair 400 or seat also with a shell 410 having a seat 420 and an inclined backrest 430 and a deformable member 450 placed in the cavity of the seat 420 and the backrest 430.

Les figures 6 à 9 montrent un autre exemple de meuble 500 en forme de fauteuil selon l'invention.The Figures 6 to 9 show another example of furniture 500 in the form of an armchair according to the invention.

La vue en coupe de la figure 6 montre la structure de la coque 510 avec une assise 520 et un côté relevé formant le dossier 530.The sectional view of the figure 6 shows the structure of the hull 510 with a seat 520 and a raised side forming the file 530.

L'assise a une cavité 512 et le dossier une ouverture 515 pour être allégé tant pour le poids que pour l'aspect.The seat has a cavity 512 and the backrest an opening 515 to be lightened both for weight and appearance.

L'ouverture 515 est bordée par le prolongement du bord de l'assise 520 qui remonte et forme un rebord 532 prolongeant la cavité 512.The opening 515 is bordered by the extension of the edge of the seat 520 which rises and forms a flange 532 extending the cavity 512.

L'élément déformable 550 est représenté en vue de côté de façon séparée à la figure 7. Cet élément déformable 550 est une housse contenant une charge de matière pulvérulente ou fluide en grains ou billes.The deformable element 550 is shown in side view separately to the figure 7 . This deformable element 550 is a cover containing a charge of pulverulent material or fluid grains or balls.

La housse 511 est bordée par une surface 523 épousant la forme de la paroi latérale et plus généralement celle de la cavité 512 de l'assise 520 et du rebord 532 en creux du dossier 530. Cette housse peut même avoir une partie 524 légèrement en saillie venant s'encastrer dans l'ouverture 515 du dossier 530 jouant le rôle d'une cavité analogue à celle 512 de l'assise 520 de façon à bien tenir et retenir l'élément déformable 550 pour que celui-ci ne s'affaisse pas, tout en offrant une très grande souplesse et malléabilité par le fluage de la charge pulvérulente contenue dans la housse. L'encastrement de l'élément déformable 550 dans le dossier 530 et la forme du dossier apparaissent dans la vue en coupe de la figure 8.The cover 511 is bordered by a surface 523 matching the shape of the side wall and more generally that of the cavity 512 of the seat 520 and the rim 532 recessed backrest 530. This cover may even have a portion 524 slightly protruding fitting into the opening 515 of the backrest 530 acting as a cavity similar to that 512 of the seat 520 so as to hold and retain the deformable element 550 so that it does not sag , while offering a very great flexibility and malleability by the creep of the powdery load contained in the cover. The embedding of the deformable element 550 in the backrest 530 and the shape of the backrest appear in the sectional view of the figure 8 .

La vue de dessus de la figure 9 montre tout particulièrement la cavité 512 de l'assise qui se prolonge le long des côtés du dossier par le rebord en creux 532 servant d'appui à l'élément déformable 550.The top view of the figure 9 particularly shows the cavity 512 of the seat which extends along the sides of the backrest by the recessed rim 532 serving as a support for the deformable element 550.

Des moyens de fixation amovibles entre le dossier et la coque peuvent être prévus tant au niveau de la cavité 520 que dans la partie en creux 532 du dossier et notamment au niveau de la partie supérieure de celle-ci pour bien stabiliser l'élément déformable 550 tout en lui permettant d'offrir le maximum de confort par sa malléabilité.Removable fixing means between the backrest and the shell may be provided both at the cavity 520 and in the recessed portion 532 of the backrest and in particular at the upper part thereof to stabilize the deformable member 550 while allowing him to offer the maximum comfort by its malleability.

Suivant une variante non représentée, l'élément déformable 550 ou du moins sa housse 511 est subdivisé par exemple en deux parties tout en constituant un ensemble extérieurement solidaire pour retenir les produits pulvérulents ou billes associés au dossier dans la partie correspondant au dossier et ceux correspondant à l'assise dans la partie de l'assise, pour ne pas avoir d'accumulation complète de ces produits dans la partie inférieure de la housse lorsque l'élément déformable est installé dans la coque.According to a variant not shown, the deformable element 550 or at least its cover 511 is subdivided for example into two parts while constituting an externally integral assembly to retain the powdery products or balls associated with the folder in the part corresponding to the folder and those corresponding to the seat in the part of the seat, so as not to have a complete accumulation of these products in the lower part of the cover when the deformable element is installed in the hull.

Comme précédemment, la surface d'appui 511 de la coque peut avoir une partie en creux 535 pour former une surface d'appui simplement périphérique ou interrompue de manière à absorber les éventuelles irrégularités du sol.As before, the bearing surface 511 of the shell may have a recessed portion 535 to form a support surface simply peripheral or interrupted so as to absorb any uneven ground.

La figure 10 montre, en coupe selon XX des figures 12, 13, une autre variante de réalisation d'un siège en forme de tabouret 600, composé d'une coque 610 en forme de cylindre droit dont la section est symétrique en rotation, par exemple, carrée, polygonale ou circulaire, ou a au moins un axe de symétrie. La symétrie de rotation est prise par rapport au centre de la section ou dans le cas d'une symétrie axiale par rapport à l'axe de symétrie (symétrie plane).The figure 10 shows, in section according to XX of the Figures 12, 13 , another alternative embodiment of a stool seat 600, consisting of a shell 610 in the form of a straight cylinder whose section is symmetrical in rotation, for example, square, polygonal or circular, or has at least one axis of symmetry. The symmetry of rotation is taken with respect to the center of the section or in the case of an axial symmetry with respect to the axis of symmetry (plane symmetry).

Le dessous 611 de la coque 610 est soit fermé soit ouvert ; il constitue alors une surface d'appui périphérique.The underside 611 of the hull 610 is either closed or open; it then constitutes a peripheral support surface.

La coque 610 a une paroi périphérique 620 munie de groupes de butées 621, 622 de hauteur variable pour recevoir un fond amovible 630 de section correspondant à la section libre du cylindre. Le fond amovible 630 est muni d'un groupe de contre-butées 631 pour venir s'appuyer sur tel ou tel groupe de butées de la paroi 620 de la coque 610. Les contre-butées 631 sont réparties suivant la même disposition que les groupes de butée 621, 622, c'est-à-dire avec la même symétrie soit de rotation soit axiale de sorte qu'en retournant le fond 620 ou en le faisant tourner d'une fraction de tour, il prendra appui sur l'un ou l'autre des groupes de butées 621, 622 suivant la hauteur que l'on souhaite donner au fond.The shell 610 has a peripheral wall 620 provided with groups of stops 621, 622 of variable height to receive a removable bottom 630 of section corresponding to the free section of the cylinder. The removable bottom 630 is provided with a group of abutments 631 for abutment on this or that group of abutments of the wall 620 of the hull 610. The counterbeats 631 are distributed in the same arrangement as the groups stop 621, 622, that is to say with the same symmetry is rotational or axial so that by turning the bottom 620 or by turning a fraction of a turn, it will be supported on one either of the groups of stops 621, 622 according to the height that one wishes to give to the bottom.

La vue en coupe de la figure 10 montre le fond amovible 620 installé en position haute sur les butées 621 délimitant une cavité 612 de faible profondeur recevant un élément déformable 650 du type de ceux déjà décrits ci-dessus, dont la partie 653 venant dans la cavité 612 de la coque 610 a une surface de forme complémentaire à celle de la cavité 612 pour s'y intégrer facilement et se retenir dans celle-ci par une liaison par la forme, complétée éventuellement par un accrochage mécanique de type à microgriffes.The sectional view of the figure 10 shows the removable bottom 620 installed in the high position on the stops 621 delimiting a shallow cavity 612 receiving a deformable element 650 of the type already described above, the part 653 of which comes into the cavity 612 of the shell 610 has a complementary shape surface to that of the cavity 612 for easy integration and to be retained therein by a connection by the form, supplemented optionally by a mechanical fastening microgriff type.

La vue en perspective de la figure 11 montre la forme de la paroi périphérique 620 de la coque 610 et de deux butées 621, 622.The perspective view of the figure 11 shows the shape of the peripheral wall 620 of the shell 610 and two stops 621, 622.

La vue de dessus de la figure 12 montre la coque 610 en forme de cylindre droit de section circulaire d'axe ZZ, dont la paroi périphérique 620 est munie de deux groupes de trois butées 621, 622 de hauteur différente. Ces butées sont réparties symétriquement, c'est-à-dire de façon équiangulaire le long de la face intérieure de la coque 610.The top view of the figure 12 shows the hull 610 in the form of a straight cylinder of circular cross section ZZ axis, the peripheral wall 620 is provided with two groups of three stops 621, 622 of different height. These stops are distributed symmetrically, that is to say equiangularly along the inner face of the shell 610.

La figure 13 est une vue de dessus du fond amovible 630 muni de contre-butées 631 venant en saillie. La forme du fond en vue en plan, correspond à celle de la section libre du cylindre formé par la paroi 620 de la coque 610. Le fond 630 a une découpe double formant une poignée 632.The figure 13 is a top view of the removable bottom 630 provided with against-stops 631 projecting. The shape of the bottom in plan view, corresponds to that of the free section of the cylinder formed by the wall 620 of the shell 610. The bottom 630 has a double cutout forming a handle 632.

La figure 13A montre un détail d'un mode de réalisation d'une contre-butée 631 en forme de patte bordée de deux retours lui donnant une section en forme de U de façon à chevaucher le dessus de la butée choisie (soit la butée haute, soit la butée basse).The figure 13A shows a detail of an embodiment of a counter-abutment 631 in the form of a lug lined with two returns giving it a U-shaped section so as to overlap the top of the chosen abutment (either the upper stop or the low stop).

D'autres formes de réalisation de butées ou un nombre plus important de groupes de butées est envisageable suivant le type de siège à réaliser.Other embodiments of stops or a larger number of groups of stops is possible depending on the type of seat to achieve.

Dans le mode de réalisation décrit ci-dessus, la coque 610 avec son fond amovible 630 sont réalisés en polypropylène expansé (PPE).In the embodiment described above, the shell 610 with its removable bottom 630 are made of expanded polypropylene (EPP).
