Abstract

The seat or bed support is constituted by a number of flexible spheres (1) with an intermediate empty space (2) between them for the circulation of air. The spheres are connected to each other to form a juxtaposed layer. Several layers (A,B,C) of spheres are superposed and displaced from each other so that the spheres are housed in the spaces of the neighbouring layer and thus fitted into each other. The spheres of one layer are applied against each other along a rectangular or triangular frame. The spheres allow air ventilation to occur and enable a more or less hard structure to be obtained.

Description

L'invention se rapporte aux matelas et aux sièges, et plus généralement à des supports d'assise ou de couchage qui seraient réalisés à l'aide de systèmes souples.The invention relates to mattresses and seats, and more generally to seat supports or sleeping that would be done using systems flexible.

On connaít de multiples façons de réaliser des supports d'assise souple. Ainsi, pour les matelas, on connaít des structures formées d'un agglomérat de laine ou produit analogue renfermé dans une enveloppe.We know many ways to achieve flexible seat supports. So, for mattresses, we knows structures formed of a wool agglomerate or similar product enclosed in an envelope.

On connaít aussi des matelas réalisés à l'aide d'une pluralité de bandes de ressorts ensachés. Il existe encore des matelas en mousse dont le bloc est enveloppe dans un coutil extérieur. Mais ces matelas en mousse posent en général des problèmes d'aération et de ventilation, entraínant une condensation entre le support de matelas et le matelas. C'est pourquoi leur utilisation est recommandée avec des sommiers à lattes. Par contre, le problème se pose toujours, si le matelas est posé directement sur un support plan, par exemple, en camping ou sur un bateau. En outre, ces produits connus, ne permettent pas de donner aisément une souplesse variable, sur divers emplacements de la surface du matelas. Pour cela, il faudrait réaliser des zones plus ou moins résistantes à l'enfoncement. A cette fin, dans le cas des matelas en mousse, on connaít la solution qui consiste à découper des plots indépendants les uns des autres, séparés par des alvéoles, pouvant s'enfoncer sans incidence importante sur les plots voisins. Des plots indépendants peuvent aussi être rassemblés et maintenus dans un grillage selon une trame déterminée. Ces plots indépendants sont prévus, pour réaliser notamment des matelas antiescarres. Mais ils restent coûteux à réaliser.We also know mattresses made using a plurality of pocket spring bands. It exists still foam mattresses with a wrapped block in an outer ticking. But these foam mattresses generally pose ventilation and ventilation, causing condensation between the support mattress and mattress. This is why their use is recommended with slatted bases. On the other hand, the problem still arises, if the mattress is laid directly on a flat support, for example, camping or on a boat. In addition, these known products do not not easily give variable flexibility, at various locations on the surface of the mattress. For this would require more or less areas resistant to sinking. To this end, in the case of foam mattress, we know the solution which consists in cut blocks independent of each other, separated by cells, which can sink without significant impact on neighboring studs. Studs independent can also be brought together and maintained in a grid according to a determined frame. These studs are planned, in particular to carry out anti-squares mattress. But they remain expensive to achieve.

Pour pallier à ces divers inconvénients, le demandeur a imaginé de réaliser un matelas et, plus généralement, un support d'assise ou de couchage, à l'aide de sphères souples de diamètre et de fermeté variables, ce qui permet de réaliser des structures plus ou moins dures, cette juxtaposition de sphères pouvant aussi résoudre les problèmes d'aération évoqués précédemment.To overcome these various drawbacks, the Applicant imagined making a mattress and, more generally a seat or sleeping support, using flexible spheres of diameter and firmness variables, which allows for more structured or less hard, this juxtaposition of spheres can also solve the ventilation problems mentioned previously.

W0 82 03319, FR 1 517 971 et US 4 027 888 décrivent des supports d'assise conformes au préambule de la revendication 1.W0 82 03319, FR 1 517 971 and US 4 027 888 describe seat supports conforming to the preamble of the claim 1.

Le support d'assise selon l'invention s'en distingue par le fait que les sphères sont reliées les unes aux autres et forment au moins une nappe de sphères juxtaposées.The seat support according to the invention differs therefrom by the fact that the spheres are connected to each other others and form at least one layer of spheres juxtaposed.

Selon une autre caractéristique principale de l'invention, plusieurs nappes de sphères sont superposées et décalées les unes par rapport aux autres pour que lesdites sphères se logent dans les espaces vides intermédiaires de la nappe voisine, et que les nappes soient ainsi imbriquées entre elles. Avantageusement, les sphères d'une nappe sont appliquées les unes contre les autres selon une trame rectangulaire, ou encore selon une trame triangulaire.According to another main characteristic of the invention, several layers of spheres are superimposed and offset from each other so that said spheres are housed in empty spaces of the neighboring aquifer, and that the aquifers are thus nested between them. Advantageously, the spheres of a tablecloth are applied against each other others according to a rectangular grid, or even according to a triangular frame.

Selon des caractéristiques particulières de l'invention, les sphères sont pleines et formées d'un noyau et d'un revêtement extérieur, l'un au moins des deux étant en matière souple et élastique.According to particular characteristics of the invention, the spheres are full and formed of a core and an outer coating, at least one of two being of flexible and elastic material.

En variante, les sphères sont des balles gonflées.Alternatively, the spheres are inflated balls.

D'autres caractéristiques particulières et avantages de l'invention, ressortiront de la description qui va suivre, d'exemples non limitatifs de réalisation, dans lesquels il est fait référence aux dessins annexés qui représentent :Other special features and advantages of the invention will emerge from the description which will follow, non-limiting examples of implementation, in which reference is made to the accompanying drawings which represent:

Figure 1, une vue éclatée en perspective, montrant plusieurs nappes superposées de sphères souples à trame rectangulaire.Figure 1, an exploded perspective view, showing several layers of flexible weft spheres rectangular.

Figure 2, une vue en plan d'une nappe de sphères à trame rectangulaire. Figure 2, a plan view of a sheet of spheres to rectangular frame.

Figure 3, une vue en plan d'une nappe de sphères à trame triangulaire.Figure 3, a plan view of a sheet of spheres to triangular frame.

On a représenté, à la figure 1, une armature de matelas, constituée d'une pluralité de sphères souples 1 reliées les unes aux autres par collage. Dans cet exemple, il y a trois nappes (A, B, C) de sphères, qui se superposent.There is shown in Figure 1, a frame of mattress, consisting of a plurality of flexible spheres 1 connected to each other by gluing. In this example, there are three layers (A, B, C) of spheres, which overlap.

La nappe A est réalisée par la juxtaposition de sphères 1A en carré, c'est-à-dire les sphères forment des rangées et des colonnes placées côte à côte, chaque sphère étant appliquée contre une sphère de la rangée et de la colonne voisine, selon une trame rectangulaire, comme on le voit plus précisément à la figure 2. Un espace 2 est ménagé entre chacune des quatre sphères voisines de la nappe A.The tablecloth A is produced by the juxtaposition of 1A spheres in a square, i.e. the spheres form rows and columns placed side by side, each sphere being applied against a sphere in the row and from the neighboring column, according to a rectangular grid, as seen more precisely in Figure 2. A space 2 is provided between each of the four spheres neighbors of tablecloth A.

La nappe B est réalisée de la même façon, mais elle est décalée par rapport à la nappe A, de telle façon que les sphères 1B se logent dans les espaces 2 de la nappe A. Chaque sphère 1B est ainsi en appui contre quatre sphères de la nappe A, ce qui contribue à l'imbrication des nappes entre elles.The tablecloth B is made in the same way, but it is offset from the tablecloth A, so that the spheres 1B are housed in the spaces 2 of the sheet A. Each sphere 1B is thus supported against four spheres of tablecloth A, which contributes to the nesting tablecloths between them.

La nappe C est identique et également décalée par rapport à la nappe B, pour que l'imbrication des sphères 1C dans les sphères 1B se fasse de la même manière.The tablecloth C is identical and also offset by relation to the tablecloth B, so that the nesting of the spheres 1C in the spheres 1B is done in the same way.

Dans la variante de réalisation illustrée à la figure 3, les sphères de chaque nappe sont juxtaposées selon une trame triangulaire, l'espace 2 étant délimité par trois sphères voisines. Les nappes supérieures sont également décalées comme dans l'exemple précédent pour s'imbriquer en quinconce les unes dans les autres.In the alternative embodiment illustrated in Figure 3, the spheres of each tablecloth are juxtaposed according to a triangular grid, space 2 being delimited by three neighboring spheres. The upper layers are also offset as in the previous example for overlap one into the other.

Grâce à ces assemblages, et aux espaces vides intermédiaires 2 qu'ils ménagent, l'air peut circuler librement entre les sphères, ce qui assure une bonne ventilation du matelas.Thanks to these assemblies, and the empty spaces 2 intermediaries they spare, air can circulate freely between the spheres, which ensures good ventilation of the mattress.

Le diamètre et la fermeté des sphères, permettent de réaliser des structures plus ou moins souples, et éventuellement variables sur la surface du matelas. Les sphères en question sont des sphères pleines, réalisées en une matière homogène, par exemple en mousse. Elles peuvent aussi être constituées d'un noyau souple et élastique, revêtu d'une membrane ou d'un noyau dur coiffé d'une enveloppe épaisse souple. Ainsi, l'un ou l'autre, au moins, du noyau et de son revêtement extérieur, est-il réalisé en matière souple et élastique. Les sphères peuvent aussi être des balles gonflées, à la manière des balles de tennis. Elles sont réalisées unitairement ou sont préassemblées par chapelet ou en plaques. Leur collage les unes aux autres intervient aux points de tangence. Au lieu d'un collage, on peut aussi les assembler par clipsage, ou les relier par des fils, ou encore les loger dans des filets ou des sacs formant des chapelets.The diameter and firmness of the spheres allow make more or less flexible structures, and possibly variable on the surface of the mattress. The spheres in question are solid spheres, realized in a homogeneous material, for example foam. They can also be made of a flexible core and elastic, covered with a hard cap or membrane a thick flexible envelope. So, one or the other, at least, from the core and its outer coating, is it made of flexible and elastic material. The spheres can also be inflated balls, like tennis balls. They are carried out individually or are pre-assembled in strings or in plates. Their bonding to each other occurs at points of tangency. Instead of a collage, we can also assemble by clipping, or connect them by wires, or still house them in nets or bags forming rosaries.

Les nappes de sphères utilisées, sont en nombre variable selon l'épaisseur recherchée du support. La structure ainsi constituée peut servir de base à la fabrication de matelas, de sommiers, de sièges etc. ...The tablecloths of spheres used, are in number variable according to the desired thickness of the support. The structure thus formed can serve as a basis for manufacture of mattresses, box springs, seats etc. ...
