Description

ELEMENT GONFLABLE ADAPTE A FORMER A L'ETAT GONFLE UNE PAROI PLANE, ET STRUCTURE COMPORTANT UNE TELLE PAROIINFLATABLE ELEMENT SUITABLE FOR FORMING A FLAT WALL IN THE INFLATED CONDITION, AND STRUCTURE COMPRISING SUCH A WALL
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. On connaît 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. 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. 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.The present invention also relates to a structure comprising one or more substantially planar walls, at least one of the planar walls being an inflatable element of the preceding type. There is known an inflatable element adapted to form in the inflated state a flat wall, this element consisting of two textile plies connected to each other by threads each attached to these two plies, each of these plies being formed of '' a textile layer proper, to which the threads are fixed, covered with an airtight outer covering, these sheets being joined to each other at their periphery by a seal which is also airtight, said element comprising at least one inflation valve with non-return valve. Such an element can be produced according to the velvet weaving process. Each textile sheet may be coated, at least on its outer face, by coating or laminating, with a coating which is airtight and, of course, water and liquid. In the inflated state, the two textile plies are held parallel to one another by the son, of constant length, which are each fixed to the two plies.
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.It is known that after filling with a gas, for example air, a rigid planar structure is obtained with an internal pressure of a few hundred grams.
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 the bottom of inflatable boats, the two textile sheets being able to be easily glued or welded together or independently from each 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. ^^ ^ REMpLACEMENT (REGLE 26) 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.However, such an inflatable element is not suitable for forming part of a three-dimensional structure suitable for being used as a work and / or living space. ^^ ^ REPLACEMENT (RULE 26 ) The object of the present invention is to remedy the drawbacks of known inflatable elements, and to propose an inflatable element of the aforementioned type adapted to form in the inflated state a substantially planar wall of a working or living structure, this element inflatable that can be integrated into said structure easily and reliably.
Suivant un premier aspect de l'invention, l'élément gonflable du type précité est caractérisé en ce que le moyen de liaison se présente, 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, et en ce qu'il 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.According to a first aspect of the invention, the inflatable element of the aforementioned type is characterized in that the connecting means is, along at least one peripheral edge, in the form of an elongated or joined edge element covering each of the plies and fixed longitudinally thereto, for example by gluing or by welding, and in that it comprises main retaining means secured to one of said plies and adapted to cooperate with complementary retaining means secured to a wall adjacent to said peripheral edge so as to permanently urge said peripheral edge in the direction of said adjacent wall to press said peripheral edge against said adjacent wall in the inflated state of said inflatable element.
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. L'élément gonflable selon la présente invention est donc parfaitement adapté à former une paroi d'une structure quelconque de travail ou d'habitation.Since each peripheral edge of this inflatable assembly can be urged permanently against an adjacent wall, it is thus possible to establish between the inflatable element and such an adjacent wall a rigid connection, although simple and reliable, and watertight or substantially watertight from the causes the edge of the inflatable element to be pressed and therefore slightly crushed against said adjacent wall. The inflatable element according to the present invention is therefore perfectly suited to forming a wall of any work or housing structure.
Suivant un autre aspect de l'invention, la structure du type précité comportant une ou plusieurs parois sensiblement planes est caractérisée en ce que l'une au moins des parois sensiblement planes est constituée d'un élément gonflable selon le premier aspect de la présente invention.According to another aspect of the invention, the structure of the aforementioned type comprising one or more substantially planar walls is characterized in that at least one of the substantially planar walls consists of a inflatable element according to the first aspect of the present invention.
Les moyens de retenue principaux et les moyens de retenue complémentaires constituent une liaison amovible. Les moyens de retenue principaux et les moyens de retenue complémentaires constituent une liaison élastique.The main retaining means and the complementary retaining means constitute a removable connection. The main retaining means and the complementary retaining means 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 comprise a strip fixed on a ply along the peripheral edge, the strip having along its longitudinal edge adjacent to said peripheral edge retaining elements such as hook-and-loop strip, zipper rack, tie rods, cords, etc.
Des moyens de retenue sont prévus sur chaque nappe le long dudit bord périphérique. 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. Des tirants relient l'élément gonflable au profilé.Retaining means are provided on each ply along said peripheral edge. The structure comprises a base on which side walls are fixed, at least one of which is constituted by an inflatable element and to fix said inflatable element to the base, an elongated profile is used, of 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 making it possible to introduce between the ribs the corresponding peripheral edge of said inflatable element in the inflated state. 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 1' invention. D' autres particularités et avantages de la présente invention apparaîtront dans la description détaillée ci- après .The structure comprises a central part substantially in the shape of a rectangular parallelepiped comprising a base and at least one lateral wall articulated along its lower longitudinal edge adjacent to the base so as to be able to be folded down substantially parallel to said base and to receive elements forming side walls and an element forming a roof in order to constitute a lateral structure extending laterally the central structure, at least some of the elements forming the side walls and the element forming the roof are constituted by inflatable elements according to the invention. Other features and advantages of the present 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 form of a rectangular parallelepiped constructed on a base 2 and consisting of substantially planar walls, 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 later.
Le socle 2, représenté comme un socle classique en matériau dur pourrait également être constitué par un élément gonflable comme les autres parois. 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. 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. 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.The base 2, shown as a conventional base made of hard material, could also consist of an inflatable element like the other walls. The front wall 2 includes a door 7 which can be a door made of conventional material pivoting around a frame also made of conventional material. The door 7 can also be constituted by an inflatable element of the same type as the walls 3, 4, 5 and 6. FIG. 2 shows a more complex structure 8 comprising a central structure 9, produced in this example in conventional material , shaped rectangular parallelepiped. The central structure 9 comprises a base 10 and two side walls 11. Each side wall 11 is articulated along an axis 12 along its lower longitudinal edge 13 adjacent to the base 10. Each side wall 11 can thus be folded outwards from the structure 9 until being substantially parallel to the base 10. In this folded position, each side wall 11 can receive elements forming side walls 14, 15 and a roofing element 16 so as to constitute a side structure 17 extending laterally 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 the side walls and of the element 16 forming the roof are constituted by inflatable elements similar to the inflatable elements represented in FIG. 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. 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) .As shown diagrammatically in FIG. 5, the inflatable element 18 according to the invention, adapted to form in the inflated state a substantially flat wall, consists of two textile sheets 19, 20 connected to one another by threads 21 each attached to these two plies 19, 20. The threads 21 are any known textile threads, for example made of natural, synthetic or glass fibers. Each of these plies is formed by a textile layer proper 19a, 20a, for example made of polyester, to which the threads 21 are fixed, and is covered on its outer face with an outer covering 22 airtight and water, for example PVC. These plies are joined to each other at their periphery by an edge element or joint 23, glued or welded or produced in any known manner, this joint 23 also being airtight and water tight. . Each inflatable element 18 comprises at least one inflation valve 24 comprising a built-in non-return valve (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 Figures 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 plies 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 complementary retaining means integral with a wall adjacent to said peripheral edge 25 so as to permanently urge 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 joint 23 comprises, in the example of FIG. 5, a central textile layer covered on each face with a waterproof plastic coating to allow easy welding or bonding to the plies 19, 20 and to ensure the sealing 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 an adjacent wall is flattened slightly against this wall and achieves an 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 FIG. 3, the retaining means and the complementary retaining means constitute a removable connection, which facilitates handling and transport operations before assembly and after disassembly of 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 comprise a strip 26 fixed to a textile sheet 19, 20 along the corresponding peripheral edge 25. The strip 26 has, along its longitudinal edge 27 adjacent to the peripheral edge 25, retaining elements such as hook-and-loop strips 28 or zipper racks 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, in the inflated state, a remarkable rigidity which allows their use as a wall of a structure. However, these elements are locally slightly deformable, which makes it possible to ensure a connection in tension with the retaining means, hook-and-loop bands 28 or zipper racks 29 by locally pulling on the band. 26 before fixing the retaining means to the corresponding complementary retaining means of the adjacent wall.
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 in the upper part of FIG. 3, retaining means 28, 29 are provided on each textile ply 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 complementary waterproof cover 40 covers the roofing element 16 and is fixed to the inflatable elements forming the side walls 4 for example by self-gripping bands 28 of Velcro® band 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. 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 the example shown in Figure 4, an elongated profile 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 distance predetermined for introducing between these ribs 34, 35 the peripheral edge 25 corresponding to an inflatable member 18 in the inflated state. 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 on the base 33 by means of 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 an elastic connection. The tie rods 36 can also be replaced by 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 from one wall to another or to a base can be used. Thus, in FIG. 3, the left wall 4 is connected by tie rods 36 to the solid base, and by rack and pinion closure 29 to the roof 6. The right wall 4 is connected by rack and pinion closure 29 to the base, which it is hard or that it is an inflatable element.
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 standardized dimensions of a container respecting the road and rail gauges. The structure 9 can thus be easily transported and deposited in any place where it can be deployed to form the complex structure 8 of FIG. 2. This structure is waterproof against water, air, and therefore bacteria, winds sand, etc., can have many applications, both civil and military. In the latter case, the structure 8 can be fitted inside if necessary an electromagnetic shielding and means of filtration, purification and treatment of air.
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 economical, rigid and insulating structures in the inflated state, compact and easy to fold, store, transport in the deflated state. The retaining means can be assembled in the inflated state or in the deflated state. The structures in the inflated state can obviously be reinforced by known means, internal reinforcements or arches, shrouds, etc., (not shown) to resist wind and external conditions.
D'excellents résultats peuvent ainsi être obtenus par exemple avec un élément gonflable d' environ 5 cm d' épaisseur. 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.Excellent results can thus be obtained for example with an inflatable element about 5 cm thick. Of course, the present invention is not limited to the embodiments which have just been described and many modifications and modifications can be made to them 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 include a complementary structure on one side of the central structure. The longitudinal side wall 11 can of course comprise two articulated panels, one at its lower part to constitute a base, the other at its upper part to constitute a roofing element, the inflatable elements simply constituting the side walls of the structure complementary .
