Abstract
Description
PRODUIT GONFLABLE EN ELASTOMERE. ET EN PARTICULIER EN CAOUTCHOUC. INFLATABLE ELASTOMERIC PRODUCT. AND PARTICULARLY IN RUBBER.
La présente invention concerne un produit gonflable en élastomère et, en particulier, comprenant au moins trois couches élastiques, la couche centrale étant reliée,par des régions ne se recouvrant pas et disposées sur les deux surfaces latérales, aux surfaces supérieure et inférieure formant simul tanément les surfaces extérieures du produit d'une maniere telle que, à l'état gonflé, le produit fournisse la forme recherchée et la conserve en cours d'utilisation. The present invention relates to an inflatable elastomer product and, in particular, comprising at least three elastic layers, the central layer being connected, by regions not overlapping and arranged on the two lateral surfaces, to the upper and lower surfaces simultaneously forming the outer surfaces of the product in such a way that, when inflated, the product provides the desired shape and keeps it in use.
Le produit peut être constitué de caoutchouc naturel ou synthétique, de différents polymères, de systèmes de textileXelastomère ou, éventuellement, d'une association de ceux-ci. De plus, le produit comprend au moins trois couches élastomères mais, en fonction de la destination finale de celui-ci, le nombre des couches peut être accru: en fait, le nombre de couches centrales fixé respectivement aux différentes surfaces sur chacune de ces faces, peut être également multiplie. The product can consist of natural or synthetic rubber, different polymers, textile-elastomer systems or, optionally, a combination of these. In addition, the product comprises at least three elastomeric layers, but, depending on its final destination, the number of layers can be increased: in fact, the number of central layers fixed respectively to the different surfaces on each of these faces , can also be multiplied.
Les produits gonflables en élastomère comprennent principalement différents articles de camping en caoutchouc ou textile caoutchouté; on a également fait plusieurs produits en différents polymères de synthèse. Inflatable elastomer products mainly include various rubber or rubberized textile camping items; several products have also been made from different synthetic polymers.
Selon un procédé antérieur de production de produits gonflables, on a formé deux couches cellulaires; cependant, ce procédé est incapable de satisfaire aux nécessités actuelles. Ces produits sont principalement constitues de textile revêtu de caoutchouc. On connait également des produits à deux couches, dépourvus de textile, formés à partir de feuillessynthétiques,par collage ou soudure; de tels produits servent principalement d'articles saisonniers permettant d'enrichir l'assortiment et ne satisfont pas aux exigences actuelles. According to a prior process for producing inflatable products, two cellular layers were formed; however, this process is unable to meet current needs. These products are mainly made of textile coated with rubber. There are also known two-layer products, devoid of textile, formed from synthetic sheets, by gluing or welding; such products are mainly used as seasonal items to enrich the assortment and do not meet current requirements.
Les caractéristiques les plus importantes des produits gonflables et les problèmes associés à leur production sont principalement représentés par les matelas simples ou doubles, comprenant deux ou trois élements, ou garnitures de sièges appartenant au groupe des produits exploitant un système de textile/caoutchouc. The most important characteristics of inflatable products and the problems associated with their production are mainly represented by single or double mattresses, comprising two or three elements, or seat covers belonging to the group of products operating a textile / rubber system.
Les exigences les plus importantes peuvent être résumées de la façon suivante: stabilité de la dimension et de'la forme, résistance aux intempéries (eau et soleil) et aptitude à supporter des charges.The most important requirements can be summarized as follows: dimension and shape stability, weather resistance (water and sun) and ability to withstand loads.
Cependant, de telles exigences - associées à une demande croissante de confort ne peuvent être satisfaites que par un choix correct des matériaux, par des dessins sophistiques et un coût important de fabrication, la confection pouvant être difficilement mécanisée étant donné l'importance du travail.However, such requirements - associated with an increasing demand for comfort can only be satisfied by a correct choice of materials, by sophisticated designs and a significant manufacturing cost, the confection being difficult to mechanize given the importance of the work.
La Compagnie française Hutchinson a mis au point plusieurs brevets permettant de contrôler la distance entre les parois des éléments gonflés, à l'aide de nervures de renforcement - 'loir par exemple, les brevets français
Nos. 2 082 500 et 2 136 194, respectivement. Malgré les solutions impliquées dans ces brevets, on ne peut réduire ni la quantité de travail ni les carac teristiques requises pour les matériaux.The French company Hutchinson has developed several patents allowing the distance between the walls of the inflated elements to be controlled, using reinforcement ribs - for example, the French patents
Our. 2,082,500 and 2,136,194, respectively. Despite the solutions involved in these patents, neither the amount of work nor the characteristics required for the materials can be reduced.
Le brevet No. 2 049 264 de la Compagnie Pennel et Flipo fournit une solution dans laquelle les nervures de renforcement composées de bandes due textile sont entourees d'un ou de plusieurs fils métalliques disposés en hélice ou en boucle. En utilisant cette possibilité, on a pu rendre plus avantageuse et plus économique la fabrication d'articles gonflables contenant de telles nervures de renforcement, cependant, les problèmes fondamentaux restent toujours. Patent No. 2,049,264 to the Pennel and Flipo Company provides a solution in which the reinforcing ribs composed of textile bands are surrounded by one or more metal wires arranged in a helix or loop. By using this possibility, it has been possible to make the manufacture of inflatable articles containing such reinforcing ribs more advantageous and more economical, however, the fundamental problems still remain.
Comme le camping et le tourisme se developpe de plus en plus, on a de plus en plus besoin d'articles gonflables, en particulier d'articles de camping. Les exigences quantitatives et qualitatives s'accroissant de plus en plus, exigent la mise au point d'une solution, permettant de réduire partiellement les besoins en matériaux et en main d'oeuvre, et d'alimenter le marché en produits gonflables satisfaisant aux exigences actuelles. As camping and tourism grows more and more, there is an increasing need for inflatable items, especially camping items. Quantitative and qualitative requirements increasing more and more, require the development of a solution, making it possible to partially reduce the needs in materials and labor, and to supply the market with inflatable products satisfying the requirements current.
On a résolu ce problème en modifiant la structure du produit et en la fabriquant selon l'invention. This problem was solved by modifying the structure of the product and manufacturing it according to the invention.
Selon la présente invention, on obtient des produits gonflables et, en particulier, des articles de camping, d'une façon tout à fait nouvelle, différente de celle qui est mise en oeuvre dans l'art anterieur, utilisant des nervures de renforcement. On peut donc obtenir un produit qui réponde complètement aux exigences actuelles; a cOté d'une utilisation plus avantageusedu matériau servant traditionnellement à ce propos, le travail de fabrication peut être fortement réduit et mécanisé. According to the present invention, inflatable products and, in particular, camping articles are obtained, in a completely new manner, different from that which is used in the prior art, using reinforcing ribs. We can therefore obtain a product that completely meets current requirements; Besides more advantageous use of the material traditionally used for this purpose, the manufacturing work can be greatly reduced and mechanized.
Dans plusieurs cas, on peut obtenir les paramètres qualitatifs recherches avec une composition de matériau plus simple et une consommation plus faible. In several cases, the qualitative parameters sought can be obtained with a simpler composition of material and lower consumption.
Selon la présente invention, le produit gonflable en élastomère, en particulier en caoutchouc, est caractérisé en ce qu'il comprend au moins trois couches élastomères et qu'il est formé de telle sorte que deux régions de chaque face de la couche centrale,ne se recouvrant pas l'une l'autre, sont fixées aux couches adjacentes de façon stable, tandis que la-partie libre de la couche membraneuse centrale établit une liaison ininterrompue entre les deux surfaces extérieures; il en résulte que le produit gonflé présente la configuration recherchée et la conserve au cours d'une utilisation correcte. According to the present invention, the inflatable elastomer product, in particular rubber, is characterized in that it comprises at least three elastomer layers and that it is formed so that two regions of each face of the central layer, do not not overlapping each other, are fixed to the adjacent layers in a stable manner, while the free part of the central membranous layer establishes an uninterrupted connection between the two exterior surfaces; it follows that the inflated product has the desired configuration and keeps it during correct use.
La liaison ininterrompue entre les surfaces d'une certaine dimension et configuration des couches uniques est formée en fonction des propriétés du matériau par vulcanisation, soudure ou toute autre méthode de liaison connue. The uninterrupted bond between surfaces of a certain size and configuration of single layers is formed according to the properties of the material by vulcanization, welding or any other known bonding method.
En choisissant l'épaisseur de la membrane centrale, l'élasticité et la dimension de la surface de liaison, ainsi qu'en ajustant la proportion convenable entre les surfaces libres et liées, l'épaisseur du produit, c'est-à-dire des couches gonflables uniques peuvent être ajustées en fonction des besoins. By choosing the thickness of the central membrane, the elasticity and the dimension of the bonding surface, as well as by adjusting the suitable proportion between the free and bonded surfaces, the thickness of the product, i.e. single inflatable layers can be adjusted as needed.
La forme des surfaces de liaison peut présenter une quelconque figure plane (cercle, carrée, ondulation); cette forme peut être identique ou différente sur chacune des faces. The shape of the connecting surfaces can have any planar shape (circle, square, undulation); this shape can be identical or different on each of the faces.
On a constaté avec surprise que, par rapport au produit de l'art antérieur, on peut obtenir selon l'invention des articles qui peuvent être utilisés convenablement sous une pression d'air inferieure (20 à 30%), si bien qu en utilisant le même matériau, on peut satisfaire à des exigences plus sévères. Etant donné la surpression intérieure plus faible, on peut utiliser avantageusement, soit du matériau plus mince, ou une autre sorte de matériau (par exemple, des textiles non-tissés àla place des textiles tissés ou simplement du caoutchouc ou des matériaux de synthèse), on peut reduire la déformation du produit par les surfaces de plus petite courbure (à l'état gonflé ou non), tandis que la différence existant entre les surfaces réelles et utiles diminue, ce qui se traduit par une économie de matériau. It was surprisingly found that, compared to the product of the prior art, it is possible according to the invention to obtain articles which can be used suitably under a lower air pressure (20 to 30%), so that by using the same material, more stringent requirements can be met. Given the lower internal overpressure, it is advantageously possible to use either thinner material or another kind of material (for example, non-woven textiles instead of woven textiles or simply rubber or synthetic materials), it is possible to reduce the deformation of the product by the surfaces of smaller curvature (in the inflated state or not), while the difference existing between the real and useful surfaces decreases, which results in a saving of material.
La structure des éléments gonflables des cellules communiquantes et contenant une membrane (intérieure) disposée au centre, c'est-à-dire la formation de surfaces uniques avec une liaison en forme de cellule, est décrite en détail à l'aide des dessins suivants dans lesquels les Figures 1 à 6 présentent différentes configurations et dimensions des surfaces de liaison disposées sur les faces des membranes, et les Figures 7 à 9 les mises en oeuvre préférées selon l'invention. The structure of the inflatable elements of the communicating cells and containing a membrane (inner) arranged in the center, i.e. the formation of single surfaces with a cell-shaped connection, is described in detail using the following drawings in which Figures 1 to 6 show different configurations and dimensions of the connecting surfaces arranged on the faces of the membranes, and Figures 7 to 9 the preferred embodiments according to the invention.
Dans la Figure l, les surfaces de liaison sont carrées et identiques. In Figure 1, the bonding surfaces are square and identical.

portant une couche textile tissée caoutchoutée sur la surface intérieure,
et reliée à la membrane disposée au centre;
les Figures7 et 9 illustrent une section droite partielle d'un produit dégonflé pourvu de textile tisse caoutchouté sur la surface intérieure, et
comprenant respectivement une ou deux membranes intérieures.In Figure 5, the connecting surfaces have an eight shape, obtained
by a displacement of 90 "and defined by circular arcs; and
Figure 6 shows connecting surfaces in the form of corrugations
as well as the membrane disposed between them;
Figure 8 shows a partial section of an inflated product
having a woven rubberized textile layer on the inner surface,
and connected to the membrane arranged in the center;
Figures 7 and 9 illustrate a partial cross section of a deflated product provided with rubberized woven fabric on the inner surface, and
comprising respectively one or two interior membranes.
La Fig.7 est une mise en oeuvre préférée selon l'invention, dans laquelle
la membrane centrale 3 est fixée à la couche 1 de textile caoutchouté superieure
selon les surfaces "a", tandis qu'elle est fixée à la couche de textile 2
caoutchoute inférieure selon la surface "b"; les cellules "c" et "d" sont
formées par les parties libres des couches de membrane disposées au centre.Fig.7 is a preferred implementation according to the invention, in which
the central membrane 3 is fixed to the layer 1 of upper rubberized textile
according to the surfaces "a", while it is fixed to the textile layer 2
lower rubber according to the surface "b"; cells "c" and "d" are
formed by the free parts of the membrane layers arranged in the center.
La partie libre 3a de la menbrane forme une liaison ininterrompue entre les deux
surfaces voisinnes et, à l'état gonfle le produit presente des cellules
communiquantes c etc qui lui confèrent la configuration recherchée et lui conservent
sa forme lors d'une utilisation convenable.The free part 3a of the menbran forms an uninterrupted connection between the two
neighboring surfaces and, when swollen, the product presents cells
communicating c etc which give it the desired configuration and keep it
its shape when properly used.
La figure 9 correspond au cas -si la menbrane centrale comprend deux couches
respectivement 3 et 3'(quoiqu'elle puisse en comprendre davantage).Dans le cas
représenté les parties libres 3'a et 3"a forment la liaison ininterrompue entre
les surfaces 1 et 2
Bien entendu, la présente invention n'est nullement limitée aux modes
de réalisation décrits et représentés; elle est susceptible de nombreuses
variantes accessibles à l'homme de l'art, suivant les applications envisagées
et sans que l'on ne s'écarte de l'esprit de l'invention. Figure 9 corresponds to the case - if the central menbrane comprises two layers
3 and 3 'respectively (although she may understand more).
shown the free parts 3'a and 3 "a form the uninterrupted connection between
surfaces 1 and 2
Of course, the present invention is in no way limited to the modes
of embodiment described and represented; she is likely to many
variants accessible to those skilled in the art, depending on the applications envisaged
and without departing from the spirit of the invention.
