Description

La présente invention concerne les matelas et, plus particulièrement les matelas à base de fibres végétales.The present invention relates to mattresses and, more particularly to mattresses based on vegetable fibers.

On connait des matelas à base de fibres végétales telle que la fibre de coco, qui présentent de grandes qualités de confort. Ils se présentent sous la forme d'une couche de fibres de coco agglomérées par des micro-particules de latex qui confèrent au matelas une certaine souplesse.We know mattresses based on vegetable fibers such as coconut fiber, which have great qualities of comfort. They come in the form of a layer of coconut fibers agglomerated by latex micro-particles which give the mattress a certain flexibility.

Les matelas peuvent être recouverts sur l'une ou leurs deux faces d'une couche en latex.Mattresses can be covered on one or both sides with a layer of latex.

On connaît également des matelas en fibres de coco recouverts sur leur face supérieure d'une couche de latex et, qui pour améliorer le confort sont composés de plusieurs parties en fibres de coco de densités différentes (densité de 60 kg/m³ à la tête et au pied, 80 kg/m³) au niveau du dos. Les parties de densités différentes sont séparées et reliées au moyen de couches transversales composées de latex.There are also known coconut fiber mattresses covered on their upper face with a layer of latex and which, to improve comfort, are composed of several coconut fiber parts of different densities (density of 60 kg / m³ at the head and at the foot, 80 kg / m³) at the back. The parts of different densities are separated and connected by means of transverse layers composed of latex.

Un inconvénient de ces différents types de matelas réside dans le fait que, quand ils sont placés sur des sommiers déformables comportant par exemple des extrémités de tête et de pied relevables, il exis­te à cause de la faible flexibilité de ces matelas un risque de rupture des fibres végétales.A disadvantage of these different types of mattresses is that, when they are placed on deformable bed bases comprising for example liftable head and foot ends, there is a risk of breakage of the mattresses because of the low flexibility of these mattresses. vegetable fibers.

Un autre inconvénient réside dans le fait que, lorsque la couche en fibres végétales est recou­verte d'une couche en mousse, cette dernière a ten­dance à former des bourrelets ou des creux à l'empla­cement des lignes de pliage du sommier.Another drawback lies in the fact that, when the layer of vegetable fibers is covered with a foam layer, the latter tends to form beads or hollows at the location of the fold lines of the bed base.

Dans le cas des matelas décrits précédemment formés de blocs de densités différentes reliés les uns aux autres au moyen d'une couche de latex, si la ligne de pliage ou de flexion est située au niveau de la couche transversale du latex, il existe un risque de décollement entre la fibre de coco et cette couche transversale de latex, tandis que, par ailleurs, la partie ou la couche supérieure de latex a tendance à former un bourrelet à la surface du matelas.In the case of the mattresses described above formed from blocks of different densities connected to each other by means of a layer of latex, if the fold or bending line is located at the level of the transverse layer of latex, there is a risk of detachment between the coconut fiber and this transverse layer of latex, while, moreover, the part or the upper layer of latex tends to form a bead on the surface of the mattress.

Le but de l'invention est d apporter de fournir un matelas à base de fibres végétales qui puisse subir une déformation localisée le long d'une ligne de pliage tout en gardant la continuité de la surface du matelas.The object of the invention is to provide a mattress based on plant fibers which can undergo localized deformation along a fold line while keeping the continuity of the surface of the mattress.

A cet effet, l'invention a pour objet un matelas comprenant au moins une couche en matériau à base de fibres végétales réalisée en au moins deux blocs dont la zone de jonction se situe à peu près dans un plan transversal, caractérisé en ce que la zone de jonction entre lesdits blocs est disposée le long d'une ligne de pliage du matelas et en ce qu'au moins au voisinage de la zone de jonction, de part et d'autre dudit plan transversal il est prévu une couche en mousse fixée sur chacune des deux faces supérieure et inférieure de la couche à base de fibres végétales.To this end, the subject of the invention is a mattress comprising at least one layer of material based on vegetable fibers produced in at least two blocks, the junction zone of which is approximately in a transverse plane, characterized in that the junction zone between said blocks is arranged along a fold line of the mattress and in that at least in the vicinity of the junction zone, on either side of said transverse plane there is provided a fixed foam layer on each of the two upper and lower faces of the layer based on vegetable fibers.

Suivant d'autres caractéristiques :
- les blocs de matériau à base de fibres vé­gétales sont jointifs ou quasiment jointifs, de telle sorte que leurs parties terminales situées de part et d'autre de la zone de jonction sont libres de s'écar­ter l'une de l'autre en formant un dièdre autour d'un axe correspondant sensiblement à la ligne de pliage, évitant ainsi tout risque de rupture des fibres végé­tales. Par jointifs ou quasi-jointifs, il faut com­prendre qu'en tout état de cause, cela signifie l'ab­sence de matériau en mousse collé sur les surfaces verticales en regard des blocs à base de fibres végétales ;
- la mousse prévue au niveau de la zone de jonction, de part et d'autre, d'un plan transversal est fixée sur la couche en fibres de coco le long de surfaces de liaison orientées parallèlement à la surface du matelas ;
- au voisinage de la zone de jonction, l'épaisseur de chacun des blocs de matériau à base de fibres végétales est inférieure à la moitié de l'é­paisseur totale du matelas ;
- au voisinage de ladite zone de jonction, les blocs de matériau à base de fibres végétales com­portent une bande d'épaisseur réduite.According to other characteristics:
the blocks of material based on vegetable fibers are contiguous or almost contiguous, so that their end portions located on either side of the junction zone are free to move apart from one another by forming a dihedral around an axis corresponding substantially to the fold line, thus avoiding any risk of breaking the plant fibers. By contiguous or quasi-contiguous, it should be understood that in any event, this means the absence of foam material bonded to the vertical surfaces facing the blocks based on vegetable fibers;
- the foam provided in the area of junction, on both sides, of a transverse plane is fixed on the coconut fiber layer along connecting surfaces oriented parallel to the surface of the mattress;
- in the vicinity of the junction zone, the thickness of each of the blocks of material based on plant fibers is less than half the total thickness of the mattress;
- In the vicinity of said junction zone, the blocks of material based on vegetable fibers comprise a strip of reduced thickness.

Une mousse préférée pour la réalisation des matelas selon l'invention est une mousse de latex naturel et la fibre végétale est de préférence la fibre de coco agglomérée par des micro-particules de latex naturel.A preferred foam for producing the mattresses according to the invention is a natural latex foam and the vegetable fiber is preferably coconut fiber agglomerated with natural latex micro-particles.

Avantageusement, la densité de la mousse est sensiblement la même que celle de la couche en maté­riau à base de fibres végétales.Advantageously, the density of the foam is substantially the same as that of the layer of material based on vegetable fibers.

L'invention est exposée ci-après plus en dé­tail en se référant aux dessins annexés sur lesquels :

  • - la Fig.1 est une vue partielle en coupe longitudinale d'un matelas selon une première forme de réalisation de l'invention ;
  • - la Fig.2 est une vue en coupe longitudi­nale du même matelas, en position pliée ;
  • - la Fig.3 est une vue en coupe longitudi­nale d'un matelas selon une seconde forme de réalisa­tion de l'invention ; et
  • - la Fig.4 est une vue en coupe longitudi­nale d un matelas selon une troisième forme de réa­lisation de l'invention.
The invention is set out below in more detail with reference to the accompanying drawings in which:
  • - Fig.1 is a partial view in longitudinal section of a mattress according to a first embodiment of the invention;
  • - Fig.2 is a longitudinal sectional view of the same mattress, in the folded position;
  • - Fig.3 is a longitudinal sectional view of a mattress according to a second embodiment of the invention; and
  • - Fig.4 is a longitudinal sectional view of a mattress according to a third embodiment of the invention.

Dans la première forme de réalisation il­lustrée par la Fig.1, le matelas comprend au moins deux blocs 1,2 de matériau à base de fibres végétales disposés bout à bout dans le sens longitudinal du matelas. La zone de jonction, située dans un plan transversal par rapport à cette direction longit­udinale est désignée par la référence 3. Chaque bloc comporte au niveau de la zone de jonction une partie terminale 4,5 d'épaisseur réduite située dans la par­tie médiane de chacun des blocs. Ces derniers déli­mitent ainsi de part et d'autre de la zone de jonction et sur les faces supérieure et inférieure du matelas, un évidement 6, 7. Chaque évidement est rempli d'une bande ou couche 8, 9 de matériau en mousse fixée par exemple par collage sur lesdites parties terminales. Ce collage est effectué de préférence sur les surfaces horizontales 10 et verticales 11 délimitant les évi­dements 6, 7. La largeur de l'évidement est avanta­geusement de 25 cm.In the first embodiment illustrated in FIG. 1, the mattress comprises at least two blocks 1,2 of material based on vegetable fibers arranged end to end in the longitudinal direction of the mattress. The junction zone, located in a transverse plane with respect to this longitudinal direction is designated by the reference 3. Each block comprises at the junction zone a terminal part 4.5 of reduced thickness located in the middle part of each blocks. The latter thus delimit on either side of the junction zone and on the upper and lower faces of the mattress, a recess 6, 7. Each recess is filled with a strip or layer 8, 9 of foam material fixed by example by gluing on said end portions. This bonding is preferably carried out on the horizontal 10 and vertical 11 surfaces delimiting the recesses 6, 7. The width of the recess is advantageously 25 cm.

Quand le matelas est en position pliée, comme sur la Fig.2, les parties terminales 4, 5 des blocs de matériau en fibres végétales s'écartent l'une de l'autre pour former un dièdre 12. Les bandes de mousse 8, 9 se trouvant au-dessus et au-dessous de la zone de jonction se déforment et s'étirent, grâce aux propriétés d'élasticité du latex. On constate que de cette manière, en cas de flexion du matelas, les forces s'appliquent principalement tangentiellement à la surface de liaison de la couche en mousse avec la couche en fibres végétales et ne provoquent pas d'ar­rachement.When the mattress is in the folded position, as in FIG. 2, the end portions 4, 5 of the blocks of vegetable fiber material separate from one another to form a dihedral 12. The strips of foam 8, 9 located above and below the junction zone deform and stretch, thanks to the elasticity properties of the latex. It is noted that in this way, in the event of bending of the mattress, the forces are applied mainly tangentially to the bonding surface of the foam layer with the layer of vegetable fibers and do not cause tearing.

Dans une seconde forme de réalisation, le matelas comprend une couche de matériau en mousse 8 fixée sur toute une face de la couche en matériau à base de fibres végétales. Du fait de la présence de cette couche en mousse 8, un seul évidement 7 est nécessaire. L'évidement 7 d'une largeur de l'ordre de 25 cm est situé sur la face à base de fibres végétales non recouverte de mousse et rempli d'une couche ou bande de matériau en mousse 9 fixée sur les parties terminales 4 et 5.In a second embodiment, the mattress comprises a layer of foam material 8 fixed on an entire face of the layer of material based on vegetable fibers. Due to the presence of this foam layer 8, only one recess 7 is necessary. The recess 7 with a width of the order of 25 cm is located on the face based on vegetable fibers not covered with foam and filled with a layer or strip of foam material 9 fixed on the terminal parts 4 and 5.

Dans la troisième forme de réalisation, le matelas comprend fixée sur chaque face de la couche à base de fibres végétales une couche en matériau en mousse 8 et 9. Du fait de cette structure en trois couches, il n'est pas nécessaire de prévoir d'évide­ment.In the third embodiment, the mattress comprises fixed on each face of the layer based on plant fibers a layer of foam material 8 and 9. Because of this three-layer structure, it is not necessary to provide 'of course.

Pour la même raison, l'épaisseur des parties terminales 4 et 5 des blocs 1 et 2 se situant de part et d'autre de la zone de jonction 3 n'est pas réduite, l'épaisseur de la couche en fibres végétales étant sensiblement la même sur toute la longueur du matelas.For the same reason, the thickness of the terminal parts 4 and 5 of the blocks 1 and 2 located on either side of the junction zone 3 is not reduced, the thickness of the layer of vegetable fibers being substantially the same over the entire length of the mattress.

Il est avantageux que l'épaisseur des blocs en fibres végétales soit de l'ordre d'un tiers de l'épaisseur totale du matelas, ce qui permet de réa­liser facilement sur le plan technique et de manière économique le matelas selon l'invention par assemblage et collage des blocs d'épaisseurs sensiblement égales.It is advantageous for the thickness of the vegetable fiber blocks to be of the order of one third of the total thickness of the mattress, which makes it possible to produce the mattress according to the invention easily technically and economically by assembly and bonding of blocks of substantially equal thickness.

Par exemple dans le cas d'un matelas en fibres de coco selon le premier mode de réalisation, on assemble des blocs de matériau à base de fibres de coco, de façon à former trois couches superposées, les blocs de matériau à base de fibres de coco de la cou­che centrale étant décalés par rapport aux deux autres blocs de matériau à base de fibres de coco pour former une jonction telle que décrite précédemment au niveau de l'emplacement souhaité de la ligne de pliage.For example, in the case of a coconut fiber mattress according to the first embodiment, blocks of material based on coconut fibers are assembled, so as to form three superimposed layers, the blocks of material based on coconut of the central layer being offset from the other two blocks of material based on coconut fibers to form a junction as described above at the desired location of the fold line.

De même dans le cas de la Fig.3, on assemble des blocs de matériau à base de fibres de coco de ma­nière à former deux couches superposées et de façon à ce que les blocs de matériau à base de fibres de coco de la couche supérieure forment une jonction à l'em­placement souhaité de la ligne de pliage.Similarly in the case of Fig.3, blocks of material based on coconut fibers are assembled so as to form two superimposed layers and so that the blocks of material based on coconut fibers of the top layer form a junction at the desired location of the fold line.

Les matelas selon la présente invention peu­vent être des matelas pour lits, chaises longues, ca­napés, lits, etc.. Ils peuvent exister dans toutes les tailles habituelemment disponibles et être recouverts des housses traditionnellement utilisées.The mattresses according to the present invention can be mattresses for beds, deckchairs, sofas, beds, etc. They can exist in all the sizes usually available and can be covered with the covers traditionally used.

La présente invention évite les inconvé­nients de l'art antérieur en ce sens que les matelas qu'elle propose ne présentent ni rupture de la couche en fibres végétales ni discontinuité de la surface en cas de flexion. Ils sont d'une réalisation simple sur le plan technique et leur fabrication est peu onéreu­se.The present invention avoids the drawbacks of the prior art in the sense that the mattresses which it offers have neither a break in the layer of plant fibers nor a discontinuity in the surface in the event of bending. They are technically simple to make and their manufacture is inexpensive.
