Description

La présente invention concerne une structure gonflable, comprenant une enveloppe en matière souple dont le bord périphérique est relié au sol, des moyens étant prévus pour souffler de l'air à l'intérieur de l'espace compris entre le sol et l'enveloppe.The present invention relates to an inflatable structure, comprising an envelope made of flexible material, the peripheral edge of which is connected to the ground, means being provided for blowing air inside the space between the ground and the envelope.

L'air soufflé dans cet espace gonfle l'enveloppe. Ce gonflement engendre ainsi des efforts de traction entre le bord périphérique de l'enveloppe et ses moyens de liaison au sol.The air blown into this space inflates the envelope. This swelling thus generates tensile forces between the peripheral edge of the envelope and its ground connection means.

Ces structures gonflables peuvent servir d'abris provisoires ou temporaires pour tous usages.These inflatable structures can serve as temporary or temporary shelters for all uses.

Les moyens qui permettent de lier l'enveloppe au sol comprennent, dans les réalisations connues, des piquets qui sont fichés dans le sol et des liens qui relient ceux-ci au bord périphérique de l'enveloppe.The means which make it possible to link the envelope to the ground include, in known embodiments, stakes which are inserted into the ground and links which connect these to the peripheral edge of the envelope.

La mise en oeuvre de ces moyens de liaison connus est le plus souvent complexe et fastidieuse. De plus, l'efficacité de ces moyens de liaison est largement tributaire de la nature du sol.The implementation of these known connecting means is most often complex and tedious. In addition, the effectiveness of these connecting means is largely dependent on the nature of the soil.

Ainsi, dans le cas d'un sol trop meuble, ces moyens de liaison sont inefficaces, car les piquets ne tiennent pas suffisamment dans un tel sol.Thus, in the case of a too loose soil, these connecting means are ineffective, because the stakes do not hold enough in such a soil.

Par ailleurs, dans le cas d'un sol trop dur, par exemple en béton, ou trop rocailleux, il est impossible d'enfoncer les piquets.Furthermore, in the case of too hard soil, for example concrete, or too rocky, it is impossible to drive the stakes.

D'autre part, le mode de liaison ci-dessus, ne permet pas de réaliser une étanchéité suffisante entre le bord périphérique de l'enveloppe et le sol, de sorte qu'une grande partie de l'air qui est soufflé à l'intérieur de la structure s'échappe à l'extérieur. On est ainsi obligé de maintenir un débit de soufflage d'air relativement élevé, ce qui engendre un gaspillage d'énergie notamment en hiver, saison à laquelle de l'air chaud est soufflé à l'intérieur de la structure pour assurer un chauffage.On the other hand, the above connection method does not make it possible to achieve a sufficient seal between the peripheral edge of the envelope and the ground, so that a large part of the air which is blown into the inside the structure escapes outside. It is thus necessary to maintain a relatively high air blowing rate, which generates a waste of energy especially in winter, season in which hot air is blown inside the structure to provide heating.

Le but de la présente invention, est de remédier aux inconvénients des réalisations connues, en créant une structure gonflable qui soit aisée à installer sur n'importe quel sol.The object of the present invention is to remedy the drawbacks of known embodiments, by creating an inflatable structure which is easy to install on any floor.

L'invention vise ainsi une structure gonflable comprenant une enveloppe en matière souple dont le bord périphérique est relié au sol, des moyens étant prévus pour souffler de l'air à l'intérieur de l'espace compris entre le sol et l'enveloppe.The invention thus relates to an inflatable structure comprising an envelope made of flexible material, the peripheral edge of which is connected to the ground, means being provided for blowing air inside the space between the ground and the envelope.

Suivant l'invention, cette structure est caractérisée en ce que le bord périphérique de l'enveloppe est relié à des conteneurs en matière souple posés sur le sol et renfermant un liquide, la masse du liquide contenu dans les conteneurs étant suffisante pour immobiliser l'enveloppe par rapport au sol.According to the invention, this structure is characterized in that the peripheral edge of the envelope is connected to flexible material containers placed on the ground and containing a liquid, the mass of the liquid contained in the containers being sufficient to immobilize the envelope relative to the ground.

Ces conteneurs remplis de liquide, de préférence d'eau, retiennent l'enveloppe et assurent la liaison de celle-ci par rapport au sol. Ces conteneurs, évitent ainsi l'utilisation de piquets et permettent d'ériger une structure gonflage sur n'importe quel sol, même si celui-ci présente des reliefs. En effet, les conteneurs en matière souple peuvent épouser la surface irrégulière d'un sol.These containers filled with liquid, preferably water, retain the envelope and ensure the connection thereof with respect to the ground. These containers thus avoid the use of stakes and make it possible to erect an inflation structure on any ground, even if it has reliefs. In fact, flexible material containers can follow the irregular surface of a floor.

Les conteneurs précités sont aisément transportables à l'état vide et repliés, tout comme l'enveloppe de la structure. Ce n'est que sur le site d'érection de la structure gonflable que les conteneurs sont remplis d'eau.The aforementioned containers are easily transportable in an empty state and folded up, just like the envelope of the structure. It is only at the site of erection of the inflatable structure that the containers are filled with water.

L'eau contenue dans ces conteneurs peut si nécessaire être utilisée pour lutter contre un éventuel incendie à l'intérieur de la structure.The water contained in these containers can, if necessary, be used to fight a possible fire inside the structure.

Ces conteneurs peuvent être en tissu imprégné de matière plastique telle que du polychlorure de vinyle (PVC).These containers can be made of fabric impregnated with plastic material such as polyvinyl chloride (PVC).

Selon une version préférée de l'invention, les conteneurs sont en forme de boudins sensiblement cylindriques, disposés suivant le périmètre de la base de la structure.According to a preferred version of the invention, the containers are in the form of substantially cylindrical tubes, arranged around the perimeter of the base of the structure.

Selon une version avantageuse de l'invention, les conteneurs sont posés sur un tapis souple qui enveloppe entièrement les conteneurs en formant à la base de la structure un conduit tubulaire fermé, l'enveloppe étant fixée audit tapis.According to an advantageous version of the invention, the containers are placed on a flexible mat which completely envelops the containers, forming at the base of the structure a closed tubular conduit, the envelope being fixed to said mat.

Le conduit tubulaire s'étendant autour de la base de la structure permet de réaliser une liaison sensiblement étanche entre le sol et le bord périphérique de l'enveloppe.The tubular conduit extending around the base of the structure makes it possible to produce a substantially sealed connection between the ground and the peripheral edge of the envelope.

De préférence, le tapis qui enveloppe les conteneurs comporte sur l'un de ses côtés une bande continue à laquelle est fixée le bord périphérique de l'enveloppe.Preferably, the mat which envelops the containers has on one of its sides a continuous strip to which the peripheral edge of the envelope is fixed.

Ce bord périphérique peut être facilement fixé à la bande précitée au moyen d'une fermeture à glissière qui permet de créer une liaison pratiquement imperméable.This peripheral edge can be easily attached to the aforementioned strip by means of a zipper which makes it possible to create a practically impermeable connection.

Si nécessaire, la structure peut comporter un tapis posé sur le sol à l'intérieur de la structure, le bord périphérique de ce tapis étant relié au tapis formant enveloppe pour les conteneurs.If necessary, the structure may include a mat placed on the ground inside the structure, the peripheral edge of this mat being connected to the mat forming an envelope for the containers.

Ce tapis, outre sa fonction tapis de sol, permet de relier ensemble les différents conteneurs d'eau en assurant ainsi une parfaite stabilité de la structure notamment à l'égard des vents très violents.This carpet, in addition to its floor mat function, allows the various water containers to be linked together, thus ensuring perfect stability of the structure, particularly with regard to very strong winds.

Dans la réalisation représentée sur la figure 1, la structure gonflable comprend une enveloppe 1 en matière souple par exemple en tissu imperméabilisé dont le bord périphérique 2 est relié au sol 3. Des moyens (non représentés sur la figure 1) sont prévus pour souffler de l'air à l'intérieur de l'espace 4 compris entre le sol 3 et l'enveloppe 1.In the embodiment shown in FIG. 1, the inflatable structure comprises an envelope 1 made of flexible material, for example made of waterproofed fabric, the peripheral edge 2 of which is connected to the ground 3. Means (not shown in FIG. 1) are provided for blowing the air inside the space 4 between the ground 3 and the envelope 1.

Conformément à l'invention, le bord périphérique 2 de l'enveloppe 1 est relié à des conteneurs 5 en matière souple posés sur le sol 3 et renfermant un liquide de préférence de l'eau 6. La masse d'eau contenue dans les conteneurs 5 est suffisante pour immobiliser l'enveloppe 1 par rapport au sol 3. Par conséquent, aucun piquet ou autre organe n'est prévu pour fixer l'enveloppe 1 au sol.According to the invention, the peripheral edge 2 of the envelope 1 is connected to containers 5 of flexible material placed on the ground 3 and containing a liquid preferably water 6. The mass of water contained in the containers 5 is sufficient to immobilize the envelope 1 relative to the ground 3. Consequently, no stake or other member is provided for fixing the envelope 1 to the ground.

On voit sur la figure 2 que les conteneurs sont répartis tout autour du périmètre de la base de la structure.We see in Figure 2 that the containers are distributed all around the perimeter of the base of the structure.

Les conteneurs 5 sont de préférence en tissu par exemple en polyester imprégné d'une matière plastique telle que du polychlorure de vinyle (PVC).The containers 5 are preferably made of fabric by example made of polyester impregnated with a plastic material such as polyvinyl chloride (PVC).

Dans l'exemple représenté, les conteneurs 5 sont en forme de boudins sensiblement cylindriques.In the example shown, the containers 5 are in the form of substantially cylindrical tubes.

On voit notamment sur les figures 3 et 5 que les conteneurs 5 sont posés sur un tapis souple 7 qui enveloppe entièrement les conteneurs 5 en formant à la base de la structure un conduit tubulaire 8 fermé à sa partie supérieure, par une fermeture à glissière 9.It can be seen in particular in FIGS. 3 and 5 that the containers 5 are placed on a flexible mat 7 which completely envelops the containers 5 by forming at the base of the structure a tubular conduit 8 closed at its upper part, by a zipper 9 .

Le tapis souple 7 formant enveloppe peut être en plusieurs pièces de tissu fixées l'une au bout de l'autre, en polyester imprégné de PVC.The flexible mat 7 forming an envelope can be made of several pieces of fabric fixed one at the end of the other, of polyester impregnated with PVC.

Comme indiqué sur la figure 3, le tapis 7 qui enveloppe les conteneurs 5 comporte sur son côté extérieur une bande continue 10 à laquelle est fixée au moyen d'une fermeture à glissière 11 (voir figure 4) le bord périphérique 2 de l'enveloppe 1.As shown in Figure 3, the mat 7 which envelops the containers 5 has on its outer side a continuous strip 10 to which is fixed by means of a zipper 11 (see Figure 4) the peripheral edge 2 of the envelope 1.

Le côté intérieur du tapis 7 formant enveloppe comporte une deuxième bande 12 à laquelle peut être fixée par une fermeture à glissière 13 une seconde enveloppe 1a (représentée en pointillé sur la figure 3) s'étendant à l'intérieur de la première enveloppe 1.The inner side of the carpet 7 forming an envelope comprises a second strip 12 to which a second envelope 1a (shown in dotted lines in FIG. 3) extending inside the first envelope 1 can be fixed by a zipper 13.

On voit en outre, sur les figures 1 et 3 que la structure gonflable comprend un tapis 14 posé sur le sol 3 à l'intérieur de la structure. Le bord périphérique 14a de ce tapis 14 est relié au tapis formant enveloppe 7 pour les conteneurs 5. Le tapis 7 comporte à cet effet sur son côté intérieur une bande 15 à laquelle est relié au moyen d'une fermeture à glissière 16 le tapis 14 posé à l'intérieur de la structure.It can also be seen in FIGS. 1 and 3 that the inflatable structure comprises a mat 14 placed on the ground 3 inside the structure. The peripheral edge 14a of this mat 14 is connected to the envelope forming mat 7 for the containers 5. The mat 7 for this purpose has on its inner side a strip 15 to which is connected by means of a zipper 16 the mat 14 placed inside the structure.

La figure 3 montre en outre l'installation 17 pour souffler de l'air froid ou chaud à l'intérieur de la structure.FIG. 3 also shows the installation 17 for blowing cold or hot air inside the structure.

Cette installation 17 comporte un tuyau de sortie 18 qui débouche à l'intérieur du conduit tubulaire 8 formé par le tapis 7 qui enveloppe les conteneurs 5.This installation 17 comprises an outlet pipe 18 which opens inside the tubular conduit 8 formed by the mat 7 which envelops the containers 5.

Le tapis 7 comporte des ouvertures 19 sur son côté adjacent à l'intérieur de la structure. L'air soufflé par l'installation 17 débouche ainsi à l'intérieur de la structure par les ouvertures 19 ci-dessus.The mat 7 has openings 19 on its side adjacent to the interior of the structure. The air blown by the installation 17 thus opens into the interior of the structure through the openings 19 above.

La figure 6 montre que les conteneurs 5 en forme de boudins comportent en leur intérieur des cloisons 20 de séparation s'étendant transversalement à la longueur de ces boudins. Ces cloisons 20 comportent chacune un clapet anti-retour 21. Ces clapets 21 évitent la vidange complète d'un conteneur 5 en cas de fuite d'eau. Ces clapets 21 permettent cependant le remplissage total d'un conteneur par l'ouverture remplissage 22. Une autre ouverture 23 est prévu à une autre extrémité du conteneur pour vidanger l'eau de celui-ci.FIG. 6 shows that the containers 5 in the form of tubes have inside their partitions 20 of separation extending transversely to the length of these tubes. These partitions 20 each include a non-return valve 21. These valves 21 prevent the complete emptying of a container 5 in the event of water leakage. These valves 21 however allow the complete filling of a container through the filling opening 22. Another opening 23 is provided at another end of the container to drain the water from it.

On va maintenant expliquer le mode opératoire pour l'érection d'une structure gonflable telle que décrite plus haut.We will now explain the procedure for the erection of an inflatable structure as described above.

On commence par poser sur le sol 3, le tapis central 14 et autour de lui le tapis 7 destiné à envelopper les conteneurs 5.We start by placing on the floor 3, the central mat 14 and around it the mat 7 intended to wrap the containers 5.

Les conteneurs 5 préalablement remplis d'eau sont ensuite roulé sur le tapis 7. Les parties du tapis 7 qui dépassent de part et d'autre des conteneurs 5 sont rabattues sur ceux-ci, comme montré par les flèches F de la figure 5. Les extrémités supérieures du tapis 7 sont ensuite reliées ensemble au moyen de la fermeture à glissière 9. Une opération ultérieure consiste à fixer le bord périphérique du tapis de sol 14 à la bande latérale 15 de l'enveloppe 7 au moyen de la fermeture à glissière 15.The containers 5 previously filled with water are then rolled on the mat 7. The parts of the mat 7 which protrude on either side of the containers 5 are folded down on these, as shown by the arrows F in FIG. 5. The upper ends of the mat 7 are then connected together by means of the zipper 9. A subsequent operation consists in fixing the peripheral edge of the floor mat 14 to the lateral strip 15 of the envelope 7 by means of the zipper 15.

On peut alors fixer au moyen de la fermeture à glissière 11, le bord périphérique de l'enveloppe 1 à la bande extérieure 10. Préalablement à cette opération, on peut fixer l'enveloppe intérieure 1a à la bande 12. Après mise en place de l'installation de soufflage 17, on souffle de l'air sous l'enveloppe 1 pour gonfler celle-ci et achever ainsi l'érection de la structure.We can then fix by means of the zipper 11, the peripheral edge of the envelope 1 to the outer strip 10. Before this operation, we can fix the inner envelope 1a to the strip 12. After installation of the blowing installation 17, air is blown under the envelope 1 to inflate the latter and thus complete the erection of the structure.

Il résulte du mode opératoire ci-dessus, que la structure gonflable selon l'invention est extrèmement simple à construire.It follows from the above procedure, that the inflatable structure according to the invention is extremely simple to construct.

Etant donné que cette construction ne nécessite aucun piquet ou organe de fixation analogue, elle peut être mise en oeuvre sur n'importe quel sol.Since this construction does not require any stake or similar fixing member, it can be implemented on any floor.

Les boudins ou conteneurs 5 remplis d'eau présentent l'avantage complémentaire d'épouser de très près la surface du sol 3 même lorsque celle-ci présente des reliefs, de sorte que la jonction entre ces conteneurs 5 et le sol est pratiquement étanche.The sausages or containers 5 filled with water have the additional advantage of closely marrying the surface of the ground 3 even when the latter has reliefs, so that the junction between these containers 5 and the ground is practically sealed.

Ainsi, en cas de pluie abondante, celle-ci ne risque pas de pénétrer à l'intérieur de la structure. La relative étanchéité réalisée d'une part entre l'enveloppe 1 et la tapis 7 enveloppant les conteneurs 5 et d'autre part entre ceux-ci et le sol 3, permet de limiter les fuites d'air vers l'extérieur, notamment lors du gonflage de l'enveloppe.Thus, in the event of abundant rain, there is no risk of it penetrating inside the structure. The relative tightness produced on the one hand between the envelope 1 and the mat 7 enveloping the containers 5 and on the other hand between these and the ground 3, makes it possible to limit air leaks to the outside, in particular during inflation of the envelope.

Les risques de gel en hiver de l'eau contenue dans boudins 5 sont évités du fait que l'air chaud soufflé en hiver par l'installation 17 pénètre dans le conduit 8 formé entre l'enveloppe 7 et les boudins 5 et réchauffe ces derniers, avant de pénétrer dans la structure.The risks of freezing in winter of the water contained in tubes 5 are avoided because the hot air blown in winter by the installation 17 penetrates into the duct 8 formed between the casing 7 and the tubes 5 and heats the latter , before entering the structure.

Par ailleurs, l'eau contenue dans les boudins 5 assure une sécurité en cas d'incendie à l'intérieur de la structure. Dans un tel cas, il suffit en effet, de crever un ou plusieurs boudins 5 pour que l'eau se répande à l'intérieur de la structure pour éteindre l'incendie.Furthermore, the water contained in the tubes 5 provides security in the event of a fire inside the structure. In such a case, it suffices to burst one or more tubes 5 so that the water spreads inside the structure to extinguish the fire.

Bien entendu, l'invention n'est pas limitée à l'exemple de réalisation que l'on vient de décrire et on peut apporter à celui-ci de nombreuses modifications sans sortir du cadre de l'invention.Of course, the invention is not limited to the embodiment which has just been described and can make numerous modifications to it without departing from the scope of the invention.

Ainsi, les boudins 5 d'eau peuvent être disposés les uns au bout des autres selon toute forme désirée pour la base de la structure gonflable. Cette base peut ainsi être carrée, restangulaire, hexagonale ou circulaire.Thus, the water strands 5 can be arranged one after the other in any shape desired for the base of the inflatable structure. This base can thus be square, restangular, hexagonal or circular.

Bien entendu, les boudins 5 au lieu d'être droits pourraient être arqués ou en forme d'équerre.Of course, the flanges 5 instead of being straight could be arched or square-shaped.
