Description

La présente invention concerne un élément gonflable adapté à former à l'état gonflé une paroi sensiblement plane.The present invention relates to an inflatable element adapted to form in the inflated state a substantially planar wall.

La présente invention concerne également une structure comportant une ou plusieurs parois sensiblement planes, l'une au moins des parois planes étant un élément gonflable du type précédent.The present invention also relates to a structure comprising one or more substantially planar walls, one at least flat walls being an inflatable element of the type previous.

On connaít un élément gonflable adapté à former à l'état gonflé une paroi plane, cet élément étant constitué de deux nappes textiles reliées l'une à l'autre par des fils fixés chacun à ces deux nappes, chacune de ces nappes étant formée d'une couche textile proprement dite, à laquelle sont fixés les fils, recouverte d'un revêtement extérieur étanche à l'air, ces nappes étant réunies l'une à l'autre à leur périphérie par un joint également étanche à l'air, ledit élément comportant au moins une valve de gonflage avec clapet anti-retour.We know an inflatable element adapted to form in the state inflated a flat wall, this element consisting of two textile tablecloths connected to each other by fixed threads each to these two layers, each of these layers being formed a textile layer proper, to which are attached the wires, covered with a waterproof outer coating air, these sheets being joined to each other at their periphery by a seal also airtight, said element comprising at least one inflation valve with valve check.

Un tel élément peut être réalisé selon le procédé de tissage du velours. Chaque nappe textile peut être revêtue, au moins sur sa face extérieure, par enduction ou laminage, d'un revêtement étanche à l'air et, bien entendu, à l'eau et aux liquides.Such an element can be produced according to the method of velvet weaving. Each textile tablecloth can be coated, at least on its outer face, by coating or rolling, an airtight and, of course, waterproof coating and liquids.

A l'état gonflé, les deux nappes textiles sont maintenues parallèles l'une à l'autre par les fils, de longueur constante, qui sont fixés chacun aux deux nappes.In the inflated state, the two textile layers are maintained parallel to each other by the wires, of length constant, which are each attached to the two layers.

On sait qu'après remplissage par un gaz, par exemple de l'air, on obtient avec une pression intérieure de quelques centaines de grammes, une structure plane rigide.We know that after filling with a gas, for example air, we obtain with an internal pressure of a few hundreds of grams, a rigid planar structure.

Ce produit est déjà utilisé comme fond de bateaux gonflables, les deux nappes textiles pouvant être facilement collées ou soudées ensemble ou indépendamment l'une de l'autre aux boudins gonflables de ces bateaux.This product is already used as a boat bottom inflatable, the two textile sheets can be easily glued or welded together or independently one of the other to the inflatable tubes of these boats.

Toutefois, un tel élément gonflable n'est pas adapté à faire partie d'une structure en trois dimensions adaptée à être utilisée comme local de travail et/ou d'habitation.However, such an inflatable element is not suitable for be part of a three-dimensional structure adapted to be used as work and / or living quarters.

On connaít une structure gonflable décrite dans le brevet US-2698020 A formée à partir de l'assemblage d'éléments gonflables adjacents réunis entre eux. Elle est constituée d'une enveloppe gonflable renforcée par des nervures radiale également gonflable. Cette structure est réalisée d'un seul tenant et ne comporte pas des éléments gonflables constituant une paroi individuelle.We know an inflatable structure described in the patent US-2698020 A formed from the assembly of elements adjacent inflatables joined together. It is made up an inflatable envelope reinforced by radial ribs also inflatable. This structure is made of a single holding and does not include inflatable elements constituting an individual wall.

Le but de la présente invention est de remédier aux inconvénients des éléments gonflables connus, et de proposer un élément gonflable du type précité adapté à former à l'état gonflé une paroi sensiblement plane d'une structure de travail ou d'habitation, cet élément gonflable pouvant être intégré dans ladite structure facilement et de façon fiable.The object of the present invention is to remedy the disadvantages of known inflatable elements, and to propose an inflatable element of the aforementioned type adapted to form in the state inflated a substantially planar wall of a structure of work or home, this inflatable element can be integrated into said structure easily and reliably.

L'invention concerne donc une structure comportant une ou plusieurs parois planes, dont l'une au moins des parois planes est constituée d'un élément gonflable, cet élément étant constitué de deux nappes textiles reliées l'une à l'autre par des fils fixés chacun à ces deux nappes, chacune de ces nappes étant formée d'une couche textile proprement dite, à laquelle sont fixés les fils recouverte d'un revêtement extérieur étanche à l'air, ces nappes étant réunies l'une à l'autre à leur périphérie par un moyen de liaison également étanche à l'air, ledit moyen de liaison se présentant, le long d'au moins un bord périphérique, sous la forme d'un élément de bord allongé ou joint recouvrant chacune des nappes et fixé longitudinalement à celles-ci, par exemple par collage ou par soudage, ledit élément comportant au moins une valve de gonflage avec clapet anti-retour, caractérisée en ce qu'elle comporte des moyens de retenue principaux solidaires d'une desdites nappes et adaptés à coopérer avec des moyens complémentaires de retenue solidaires d'une paroi adjacente audit bord périphérique de manière à solliciter en permanence ledit bord périphérique en direction de ladite paroi adjacente pour presser ledit bord périphérique contre ladite paroi adjacente dans l'état gonflé dudit élément gonflable, la paroi de la structure adjacente à chaque bord périphérique dudit élément gonflable comportant des moyens de retenue complémentaires des moyens de retenue principaux prévus sur l'élément gonflable le long dudit bord périphérique.The invention therefore relates to a structure comprising one or several planar walls, at least one of the walls flat consists of an inflatable element, this element consisting of two textile tablecloths, one connected to the other by wires each attached to these two layers, each of these sheets being formed of a textile layer properly said, to which are fixed the wires covered with a airtight outer covering, these sheets being joined together at their periphery by a means of also airtight connection, said connection means having, along at least one peripheral edge, under the shape of an elongated edge element or overlapping joint each of the layers and fixed longitudinally thereto, by example by gluing or welding, said element comprising at least one inflation valve with non-return valve, characterized in that it includes retaining means main integral with one of said layers and adapted to cooperate with additional means of restraint integral with a wall adjacent to said peripheral edge of so as to permanently stress said peripheral edge in direction of said adjacent wall to press said edge peripheral against said adjacent wall in the inflated state of said inflatable element, the wall of the structure adjacent to each peripheral edge of said inflatable element comprising retaining means complementary to retaining means main provided on the inflatable element along said edge peripheral.

Etant donné que chaque bord périphérique de cet ensemble gonflable peut être sollicité en permanence contre une paroi adjacente, on peut ainsi réaliser entre l'élément gonflable et une telle paroi adjacente une liaison rigide, bien que simple et fiable, et étanche ou sensiblement étanche du fait que le bord de l'élément gonflable est pressé et donc légèrement écrasé contre ladite paroi adjacente.Since each peripheral edge of this set inflatable can be permanently pressed against a wall adjacent, it is thus possible to carry out between the inflatable element and such an adjacent wall a rigid connection, although simple and reliable, and waterproof or substantially waterproof because that the edge of the inflatable element is pressed and therefore slightly crushed against said adjacent wall.

L'élément gonflable est donc parfaitement adapté à former une paroi d'une structure quelconque de travail ou d'habitation selon la présente invention. The inflatable element is therefore perfectly adapted to form a wall of any working structure or according to the present invention.

Les moyens de retenue principaux et les moyens de retenue complémentaires constituent une liaison amovible.The main means of restraint and the means of additional retainers constitute a removable connection.

Les moyens de retenue principaux et les moyens de retenue complémentaires constituent une liaison élastique.The main means of restraint and the means of additional retainers constitute an elastic connection.

Les moyens de retenue principaux comprennent une bande fixée sur une nappe le long du bord périphérique, la bande présentant le long de son bord longitudinal adjacent audit bord périphérique des éléments de retenue tels que bande auto-agrippante, crémaillère de fermeture à glissière, tirants, cordons, etc...The main retaining means include a strip fixed on a sheet along the peripheral edge, the strip having along its adjacent longitudinal edge said peripheral edge of the retaining elements such as Velcro strip, rack and pinion slide, tie rods, cords, etc ...

Des moyens de retenue sont prévus sur chaque nappe le long dudit bord périphérique.Retention means are provided on each sheet along said peripheral edge.

La structure comporte un socle sur lequel sont fixées des parois latérales dont l'une au moins est constituée par un élément gonflable et pour fixer ledit élément gonflable au socle, on utilise un profilé allongé, de section transversale en forme de U, relié audit socle, présentant des nervures formant les branches du U étant écartées l'une de l'autre d'une distance prédéterminée permettant d'introduire entre les nervures le bord périphérique correspondant dudit élément gonflable à l'état gonflé.The structure includes a base on which are fixed side walls, at least one of which is constituted by an inflatable element and for fixing said inflatable element at the base, an elongated profile is used, U-shaped cross section, connected to said base, having ribs forming the branches of the U being spaced from each other by a predetermined distance allowing the edge to be inserted between the ribs corresponding device of said inflatable element in the state inflated.

Des tirants relient l'élément gonflable au profilé.Tie rods connect the inflatable element to the profile.

La structure comprend une partie centrale sensiblement en forme de parallélépipède rectangle comportant un socle et au moins une paroi latérale articulée le long de son bord longitudinal inférieur adjacent au socle pour pouvoir être rabattue sensiblement parallèlement audit socle et recevoir des éléments formant parois latérales et un élément formant toiture afin de constituer une structure latérale prolongeant latéralement la structure centrale, certains au moins des éléments formant parois latérales et de l'élément formant toiture sont constitués par des élément gonflables selon l'invention. The structure includes a central part substantially in the shape of a rectangular parallelepiped comprising a base and at least one side wall articulated along its lower longitudinal edge adjacent to the base so that it can be folded down substantially parallel to said base and receive elements forming side walls and a roofing element to constitute a lateral structure extending laterally the central structure, at least some of the elements forming side walls and roofing element consist of inflatable elements according to the invention.

D'autres particularités et avantages de la présente invention apparaítront dans la description détaillée ci-après.Other special features and advantages of this invention will appear in the detailed description below.

On a représenté à la figure 1 une structure 1 sensiblement en forme de parallélépipède rectangle construite sur un socle 2 et constituée de parois sensiblement planes, respectivement une paroi avant 3, deux parois latérales 4, une paroi arrière 5 et une toiture 6.FIG. 1 shows a structure 1 substantially in the shape of a rectangular parallelepiped built on a base 2 and made up of walls substantially flat, respectively a front wall 3, two side walls 4, a rear wall 5 and a roof 6.

Dans l'exemple représenté, chacune de ces parois est constituée d'un élément gonflable qui sera détaillé plus loin.In the example shown, each of these walls consists of an inflatable element which will be detailed further.

Le socle 2, représenté comme un socle classique en matériau dur pourrait également être constitué par un élément gonflable comme les autres parois.The base 2, represented as a conventional base in hard material could also consist of a inflatable element like the other walls.

La paroi avant 2 comporte une porte 7 qui peut être une porte réalisée en matériau classique pivotant autour d'un cadre également en matériau classique. La porte 7 peut également être constituée par un élément gonflable du même type que les parois 3, 4, 5 et 6.The front wall 2 has a door 7 which can be a door made of classic material pivoting around of a frame also made of conventional material. Gate 7 can also consist of an inflatable element of the same type as walls 3, 4, 5 and 6.

On a représenté à la figure 2 une structure 8 plus complexe comportant une structure centrale 9, réalisée dans cet exemple en matériau classique, en forme de parallélépipède rectangle. La structure centrale 9 comporte un socle 10 et deux parois latérales 11. Chaque paroi latérale 11 est articulée suivant un axe 12 le long de son bord longitudinal inférieur 13 adjacent au socle 10.FIG. 2 shows a structure 8 plus complex comprising a central structure 9, produced in this example in classic material, in the form of rectangular parallelepiped. The central structure 9 comprises a base 10 and two side walls 11. Each wall lateral 11 is articulated along an axis 12 along its lower longitudinal edge 13 adjacent to the base 10.

Chaque paroi latérale 11 peut ainsi être rabattue vers l'extérieur de la structure 9 jusqu'à être sensiblement parallèle au socle 10. Dans cette position rabattue, chaque paroi latérale 11 peut recevoir des éléments formant parois latérales 14, 15 et un élément formant toiture 16 afin de constituer une structure latérale 17 prolongeant latéralement la structure centrale 9.Each side wall 11 can thus be folded down outwards from structure 9 until it is substantially parallel to the base 10. In this position folded down, each side wall 11 can receive side wall elements 14, 15 and an element forming roof 16 in order to constitute a structure lateral 17 laterally extending the central structure 9.

Dans l'exemple représenté, l'ensemble des éléments 14, 15 formant parois latérales et de l'élément 16 formant toiture est constitué par des éléments gonflables semblables aux éléments gonflables représentés à la figure 1.In the example shown, all of the elements 14, 15 forming side walls and element 16 forming roof is made up of inflatable elements similar to the inflatable elements shown in the figure 1.

Comme schématisé à la figure 5, l'élément gonflable 18 selon l'invention, adapté à former à l'état gonflé une paroi sensiblement plane, est constitué de deux nappes textiles 19, 20 reliées l'une à l'autre par des fils 21 fixés chacun à ces deux nappes 19, 20. Les fils 21 sont des fils textiles connus quelconques, par exemple en fibres naturelles, synthétiques ou de verre.As shown in Figure 5, the inflatable element 18 according to the invention, adapted to form in the inflated state a substantially flat wall, consists of two layers textiles 19, 20 connected to each other by threads 21 each attached to these two layers 19, 20. The wires 21 are any known textile yarn, for example of fibers natural, synthetic or glass.

Chacune de ces nappes est formée d'une couche textile proprement dite 19a, 20a, par exemple en polyester, à laquelle sont fixés les fils 21, et est recouverte sur sa face extérieure d'un revêtement extérieur 22 étanche à l'air et à l'eau, par exemple en PVC. Ces nappes sont réunies l'une à l'autre à leur périphérie par un élément de bord ou joint 23, collé ou soudé ou réalisé d'une manière connue quelconque, ce joint 23 étant également étanche à l'air et à l'eau. Chaque élément gonflable 18 comporte au moins une valve de gonflage 24 comportant un clapet anti-retour incorporé (non représenté).Each of these layers is formed by a layer textile itself 19a, 20a, for example polyester, to which the wires 21 are fixed, and is covered on its outer face of an outer coating 22 impervious to air and water, for example PVC. These tablecloths are joined together at their periphery by an element of edge or joint 23, glued or welded or made in a way any known, this seal 23 also being impervious to air and water. Each inflatable element 18 comprises at at least one inflation valve 24 comprising a non-return valve incorporated (not shown).

Dans la réalisation représentée aux figures 3 à 5, chaque élément gonflable 18 comporte le long d'au moins un bord périphérique 25, le joint 23 recouvrant extérieurement l'extrémité de chacune des nappes 19, 20 et fixé longitudinalement à celles-ci, par exemple par collage ou par soudage, et des moyens de retenue solidaires d'une des nappes 19, 20 et adaptés à coopérer avec des moyens complémentaires de retenue solidaires d'une paroi adjacente audit bord périphérique 25 de manière à solliciter en permanence le bord périphérique 25 en direction de ladite paroi adjacente pour presser ce bord 25 contre cette paroi dans l'état gonflé de l'élément gonflable 18.In the embodiment shown in FIGS. 3 to 5, each inflatable element 18 comprises along at least one peripheral edge 25, the seal 23 externally covering the end of each of the layers 19, 20 and fixed longitudinally thereto, for example by gluing or by welding, and retaining means integral with one of the plies 19, 20 and adapted to cooperate with means complementary restraint systems attached to an adjacent wall said peripheral edge 25 so as to urge permanently the peripheral edge 25 in the direction of said adjacent wall to press this edge 25 against this wall in the inflated state of the inflatable element 18.

Le joint allongé 23 comprend, dans l'exemple de la figure 5, une couche centrale textile recouverte sur chaque face d'un revêtement étanche en matière plastique pour permettre un soudage ou un collage facile aux nappes 19, 20 et pour assurer l'étanchéité du bord 25.The elongated seal 23 comprises, in the example of the Figure 5, a central textile layer covered on each side of a waterproof plastic coating for allow easy welding or bonding to the plies 19, 20 and to seal the edge 25.

Ainsi, le bord périphérique 25 pressé entre une paroi adjacente est écrasé légèrement contre cette paroi et réalise une excellente étanchéité à l'air et à l'eau.Thus, the peripheral edge 25 pressed between a adjacent wall is crushed slightly against this wall and achieves excellent air and water tightness.

Dans l'exemple représenté à la figure 3, les moyens de retenue et les moyens de retenue complémentaires constituent une liaison amovible, ce qui facilite les opérations de manutention et de transport avant montage et après démontage de la structure représentée.In the example shown in Figure 3, the means restraint and additional restraint constitute a removable connection, which facilitates handling and transport operations before assembly and after dismantling the structure shown.

Dans cet exemple, les moyens de retenue comprennent une bande 26 fixée sur une nappe textile 19, 20 le long du bord périphérique 25 correspondant. La bande 26 présente le long de son bord longitudinal 27 adjacent au bord périphérique 25 des éléments de retenue tels que bandes auto-agrippantes 28 ou crémaillères de fermeture à glissière 29.In this example, the retaining means include a strip 26 fixed to a textile sheet 19, 20 along the peripheral edge 25 corresponding. Band 26 shows the along its longitudinal edge 27 adjacent to the edge peripheral 25 retaining elements such as bands hook and loop 28 or closing racks with slide 29.

On a vu que les éléments gonflables 18 présentent à l'état gonflé, une rigidité remarquable qui permet leur utilisation comme paroi d'une structure. Toutefois, ces éléments sont localement légèrement déformables, ce qui permet d'assurer une liaison en tension avec les moyens de retenue, bandes auto-agrippantes 28 ou crémaillères de fermeture à glissière 29 en tirant localement sur la bande 26 avant de fixer les moyens de retenue aux moyens de retenue complémentaires correspondants de la paroi adjacente.We have seen that the inflatable elements 18 have at the inflated state, a remarkable rigidity which allows them use as a wall of a structure. However, these elements are locally slightly deformable, which ensures a voltage connection with the means of retainer, hook-and-loop bands 28 or racks of zipper 29 by pulling locally on the band 26 before fixing the retaining means to the means of corresponding complementary retaining walls adjacent.

Dans l'exemple représenté à la partie supérieure de la figure 3, des moyens de retenue 28, 29 sont prévus sur chaque nappe textile 19, 20 le long du bord périphérique 25.In the example shown at the top of FIG. 3, retaining means 28, 29 are provided on each textile tablecloth 19, 20 along the peripheral edge 25.

Dans cet exemple, une bâche d'étanchéité complémentaire 40 recouvre l'élément formant toiture 16 et est fixée aux éléments gonflables formant les parois latérales 4 par exemple par des bandes auto-agrippantes 28 type bande Velcro ®.In this example, a waterproof cover complementary 40 covers the roofing element 16 and is attached to the inflatable elements forming the walls side 4 for example by hook-and-loop strips 28 Velcro ® strip type.

Dans l'exemple représenté à la figure 4, un profilé allongé 32 de section transversale en forme de U est fixé au socle 33. Les nervures 34, 35 formant les branches du U sont écartées l'une de l'autre d'une distance prédéterminée permettant d'introduire entre ces nervures 34, 35 le bord périphérique 25 correspondant d'un élément gonflable 18 à l'état gonflé.In the example shown in Figure 4, a profile elongated 32 of U-shaped cross section is fixed to the base 33. The ribs 34, 35 forming the branches of the U are spaced from each other by a predetermined distance allowing to introduce between these ribs 34, 35 the edge peripheral 25 corresponding to an inflatable element 18 to swollen state.

Dans cet exemple, les moyens de retenue sont des tirants 36 fixés à une bande 26 de part et d'autre de l'élément gonflable 18. Les tirants 36 comportent à leur extrémité libre une boucle retenue au socle 33 par l'intermédiaire d'un jonc 37 par exemple en caoutchouc, traversant des oeillets 38 solidaires du profilé 32. Les tirants 36 peuvent être élastiques pour constituer une liaison élastique. Les tirants 36 peuvent également être remplacés par des cordons.In this example, the retaining means are tie rods 36 fixed to a band 26 on either side of the inflatable element 18. The tie rods 36 have at their free end a loop retained at the base 33 by via a rod 37, for example made of rubber, passing through eyelets 38 integral with the profile 32. The tie rods 36 can be elastic to constitute a elastic connection. The tie rods 36 can also be replaced with cords.

De nombreux systèmes de fixation d'une paroi à une autre ou à un socle sont utilisables. Ainsi, à la figure 3, la paroi 4 de gauche est reliée par tirants 36 au socle en dur, et par fermeture à crémaillère 29 à la toiture 6. La paroi 4 de droite est reliée par fermeture à crémaillère 29 au socle, qu'il soit en dur ou qu'il soit un élément gonflable.Many systems for fixing a wall to a other or to a base can be used. So in Figure 3, the wall 4 on the left is connected by tie rods 36 to the base in hard, and by rack and pinion 29 on the roof 6. The wall 4 on the right is connected by rack closure 29 to the base, whether it is hard or an element inflatable.

Le mode de réalisation représenté à la figure 2 peut être particulièrement utilisé comme abri mobile, la structure centrale 9 pouvant avoir les dimensions standardisées d'un conteneur respectant les gabarits routier et ferroviaire. La structure 9 peut ainsi être transportée facilement et déposée en un endroit quelconque où elle peut être déployée pour former la structure complexe 8 de la figure 2. Cette structure étanche à l'eau, à l'air, et donc aux bactéries, aux vents de sable, etc, peut avoir de nombreuses applications tant civiles que militaires. Dans ce dernier cas, la structure 8 peut être équipée à l'intérieur en cas de besoin d'un blindage électromagnétique et de moyens de filtration, de purification et de traitement de l'air.The embodiment shown in Figure 2 can be particularly used as a mobile shelter, the central structure 9 which may have the dimensions standardized of a container respecting the templates road and rail. The structure 9 can thus be easily transported and stored anywhere where it can be deployed to form the structure complex 8 of FIG. 2. This waterproof structure, to the air, and therefore to bacteria, sand winds, etc., can have many applications both civil and military. In the latter case, the structure 8 can be fitted inside if necessary shielding electromagnetic and filtration means, air purification and treatment.

Les structures de l'invention décrites ci-dessus constituent ainsi des structures économiques, rigides et isolantes à l'état gonflé, peu encombrantes et faciles à plier, à ranger, à transporter à l'état dégonflé. Les moyens de retenue peuvent être assemblés à l'état gonflé ou à l'état dégonflé. Les structures à l'état gonflé peuvent évidemment être renforcées par des moyens connus, armatures ou arceaux intérieurs, haubans, etc..., (non représentés) pour résister au vent et aux conditions extérieures.The structures of the invention described above thus constitute economic, rigid and insulating in the inflated state, space-saving and easy to fold, store, transport in a deflated state. The retaining means may be assembled in the inflated state or in the deflated state. Structures in the inflated state may obviously be reinforced by known means, reinforcements or interior arches, shrouds, etc., (not shown) to withstand wind and outdoor conditions.

D'excellents résultats peuvent ainsi être obtenus par exemple avec un élément gonflable d'environ 5 cm d'épaisseur.Excellent results can thus be obtained for example with an inflatable element of about 5 cm thick.

Bien entendu, la présente invention n'est pas limitée aux modes de réalisation que l'on vient de décrire et on peut apporter à ceux-ci de nombreux changements et modifications sans sortir du domaine de l'invention.Of course, the present invention is not limited to the embodiments just described and we can make many changes to them and modifications without departing from the scope of the invention.

Le mode de réalisation représenté à la figure 2 peut ainsi comporter une structure complémentaire d'un seul côté de la structure centrale. La paroi latérale longitudinale 11 peut bien entendu comporter deux panneaux articulés, l'un à sa partie inférieure pour constituer un socle, l'autre à sa partie supérieure pour constituer un élément de toiture, les éléments gonflables constituant simplement les parois latérales de la structure complémentaire.The embodiment shown in Figure 2 can thus have a complementary structure of a single side of the central structure. The side wall longitudinal 11 can of course have two panels articulated, one at its lower part to constitute a pedestal, the other at its upper part to constitute a roofing element, the inflatable elements constituting simply the side walls of the structure complementary.
