Description

Dispositif résistant aux chocs dus à une chute, pour le transport et la distribution de liquide, notamment de l'eau. Device resistant to shocks due to a fall, for the transport and distribution of liquid, especially water.

La présente invention a pour objet un dispositif résistant aux chocs dus à une chute pour le transport et la distribution de liquide, notamment de l'eau.The present invention relates to a shock-resistant device due to a fall for the transport and distribution of liquid, especially water.

Lors de catastrophes naturelles, par exemple les tremblements de terre ou les inondations, très souvent les sinistrés ne peuvent être atteints que par les airs, notamment par hélicoptère ou par avion. Ce mode d'intervention, s'il ne pose pas de problème pour les matières solides, qui peuvent être parachutées, pose de gros problèmes en ce qui concerne les matières liquides, notamment pour l'eau. En effet, lors du parachutage les conditionnements utilisés résistent mal aux chocs. De plus, dans certaines circonstances l'hélicoptère ne peut pas se poser, car il serait assailli par les sinistrés et pourrait être abîmé. Les récipients ou autres conditionnements doivent être jetés d'une certaine hauteur, en général de six à dix mètres.During natural disasters, for example earthquakes or floods, very often the victims can be reached only by air, especially by helicopter or by plane. This mode of intervention, if it does not pose a problem for solids, which can be parachuted, poses big problems for liquids, especially for water. In fact, during the parachuting, the packages used resist poorly to shocks. In addition, under certain circumstances the helicopter can not land, because it would be assaulted by the victims and could be damaged. Containers or other containers must be thrown from a height, usually six to ten meters.

On connaît plusieurs conditionnements antichoc pour des matières solides. Ces conditionnements sont constitués par une poche présentant une double paroi définissant un espace clos entourant ladite poche. L'objet à protéger est disposé dans la poche et l'espace clos est rempli de gaz sous pression, notamment de l'air, de manière à créer un coussin amortisseur. Les documents suivants CH 686246, US 4874093, us 7000767 décrivent de tels conditionnements.Several shockproof packages are known for solids. These packs consist of a pocket having a double wall defining a closed space surrounding said pocket. The object to be protected is placed in the pocket and the enclosed space is filled with pressurized gas, especially air, so as to create a cushion cushion. The following documents CH 686246, US 4874093, US 7000767 describe such packages.

On connaît aussi, notamment par le document US 5833069, des emballages gonflables pour des articles fragiles, tels que des bouteilles ou analogue, pour les protéger contre les chocs lors du transport.Also known, in particular from US 5833069, inflatable packages for fragile items, such as bottles or the like, to protect them against shocks during transport.

On connaît encore des récipients en matière souple destinés à contenir des liquides. Ce genre de récipients peut résister à des chocs relativement faibles, mais en général ils se rompent lors d'une chute car le liquide qu'ils contiennent est incompressible. En effet, le liquide lors de la chute crée ou provoque dans l'enveloppe une tension engendrant une déchirure.Containers made of flexible material are also known for containing liquids. This type of container can withstand relatively small shocks, but usually they break during a fall because the liquid they contain is incompressible. Indeed, the liquid during the fall creates or causes in the envelope a tension causing a tear.

Tous ces conditionnements ou emballages sont conçus pour amortir des chocs subis par des produits solides, non pour amortir une chute.All these packages or packages are designed to cushion shocks to solid products, not to cushion a fall.

L'invention a pour buts de fournir un dispositif résistant aux chocs dus à une chute, pour le transport et la distribution de liquide, notamment de l'eau. Ledit dispositif devant pouvoir supporter une chute d'au moins six à dix mètres. De plus, le dispositif doit être bon marché, car il ne sera utilisé qu'une fois.The invention aims to provide a device resistant to shocks due to a fall, for the transport and distribution of liquid, including water. Said device must be able to withstand a fall of at least six to ten meters. In addition, the device must be cheap because it will only be used once.

Ces buts sont atteints avec un dispositif résistant aux chocs dus à une chute, pour le transport et la distribution de liquide selon l'invention définie à la revendication 1.These objects are achieved with a drop-shock resistant device for the transport and dispensing of liquid according to the invention defined in claim 1.

Le titulaire a eu l'idée de combiner une enveloppe souple pour le liquide avec un coussin d'air pour absorber et amortir les chocs dus à une chute.The holder came up with the idea of combining a flexible envelope for the liquid with an air cushion to absorb and cushion the impact of a fall.

L'invention sera mieux comprise et ses caractéristiques apparaîtront plus clairement à la lecture de la description de formes d'exécution, donnée uniquement à titre d'exemple, en regard des dessins sur lesquels :The invention will be better understood and its characteristics will appear more clearly on reading the description of embodiments, given solely by way of example, with reference to the drawings in which:

La figure 1 représente schématiquement une vue en perspective d'une première forme d'exécution,FIG. 1 schematically represents a perspective view of a first embodiment,

La figure 2 représente une vue en coupe A-A du dispositif représenté à la figure 1 ,FIG. 2 represents a sectional view A-A of the device represented in FIG.

La figure 3 représente schématiquement une vue en perspective d'une seconde forme d'exécution du dispositif selon l'invention ;Figure 3 schematically shows a perspective view of a second embodiment of the device according to the invention;

La figure 4 représente une vue en coupe B-B de la seconde forme d'exécution du dispositif représenté à la figure 3. Le dispositif représenté sur les figures 1 et 2 comprend une poche 2 présentant des parois 3 et 4, qui lorsque la poche ne contient aucun liquide sont en contact, mais qui lorsque la poche est remplie par un liquide comme représenté, définissent un cylindre de section sensiblement circulaire. Les parois 3 et 4, définissent, sur leur face extérieure à la poche 2, avec les parois 5 et 6 deux espaces 7 et 8 remplis d'un gaz, par exemple de d'air. Les espaces 7 et 8 peuvent être réalisés communiquant de manière à pouvoir être remplis d'air par une seule valve 15. Il est prévu une deuxième valve 16 reliée à la poche 2 par un conduit passant à travers les espace 7 et 8, de manière à pouvoir introduire un liquide dans la poche 2FIG. 4 represents a sectional view BB of the second embodiment of the device represented in FIG. 3. The device shown in Figures 1 and 2 comprises a pocket 2 having walls 3 and 4, which when the bag contains no liquid are in contact, but which when the bag is filled with a liquid as shown, define a section cylinder substantially circular. The walls 3 and 4 define, on their outer face to the bag 2, with the walls 5 and 6 two spaces 7 and 8 filled with a gas, for example air. The spaces 7 and 8 can be made communicating so as to be filled with air by a single valve 15. There is provided a second valve 16 connected to the bag 2 by a conduit passing through the spaces 7 and 8, so that to be able to introduce a liquid into the pocket 2

Le dispositif est réalisé, dans la forme d'exécution représentée à la figure 1 , avec quatre films de matière plastique 3, 4, 5 et 6, par exemple du polyéthylène / polyamide. On fera d'abord les thermo soudures longitudinales 9 et 10, ainsi que des thermo soudures transversales 17 de manière à réaliser la poche 2. On fixera dans l'une des parois 3 et 4 une valve 16, destinée à introduire un liquide dans la poche 2. Les détails de la valve 16 ne sont pas représentés, car une telle valve est connue de l'homme du métier, notamment par le brevet US 5711691. Ensuite on réalisera les thermo soudures 11, 12, 13 et 14 créant une double paroi de la poche 2 et définissant les espaces 7 et 8 entourant la poche 2. Les espaces 7 et 8 communiquent entre eux, par des ouvertures non représentées, de manière à pouvoir remplir les espaces 7 et 8 par une seule valve15 fixée dans la paroi 5. Les espaces 7 et 8, dans une autre forme d'exécution, ne communiquent pas entre eux et il est prévu deux valves, une pour chacun des espaces 7 et 8.The device is made, in the embodiment shown in Figure 1, with four plastic films 3, 4, 5 and 6, for example polyethylene / polyamide. The longitudinal thermo-welds 9 and 10 will be made first, as well as transverse thermo-welds 17 so as to make the pocket 2. In one of the walls 3 and 4, a valve 16 will be fixed, intended to introduce a liquid into the pocket 2. The details of the valve 16 are not shown, because such a valve is known to those skilled in the art, in particular by US patent 5711691. Then we will realize the thermo welds 11, 12, 13 and 14 creating a double wall of the bag 2 and defining the spaces 7 and 8 surrounding the pocket 2. The spaces 7 and 8 communicate with each other, by not shown openings, so as to fill the spaces 7 and 8 by a single valve15 fixed in the wall 5. The spaces 7 and 8, in another embodiment, do not communicate with each other and there are two valves, one for each of the spaces 7 and 8.

Dans une autre variante, représentée aux figures 3 et 4, il est prévu plusieurs espaces indépendants en forme de tubes 41 remplis d'air, présentant chacun une valve 38, afin d'assurer un amortissement même si l'un des espaces 41 éclate.In another variant, shown in Figures 3 and 4, there are provided several independent spaces in the form of tubes 41 filled with air, each having a valve 38, to ensure damping even if one of the spaces 41 bursts.

Chaque espace 41 présente quatre parties communicantes, une partie supérieure 42, une partie inférieure 43 et deux parties d'extrémité 35 et 37 entourant une poche 40 (voir figure 4). Toutes les parties constituant un espace 41 présentent une section sensiblement circulaire.Each space 41 has four communicating portions, an upper portion 42, a lower portion 43 and two end portions 35 and 37 surrounding a pocket 40 (see Figure 4). All parts constituting a space 41 have a substantially circular section.

Le dispositif de cette deuxième forme d'exécution est réalisé avec deux feuilles 33 et 44 de matière plastique, par exemple du polyéthylène / polyamide. On disposera les deux feuilles l'une au-dessus de l'autre, et on fera les soudures 43, qui définiront des grands tubes. Ensuite, on fera les soudures 47, de manière à ne pas complètement séparer les parties 42, 35, 37 et 43, l'air introduit dans une des parties passera dans les trois autres parties. Puis on placera une valve 38 dans chaque partie. On repliera les parties 42 sur les partie 43 et on fera les soudure 36 (voir figure 4) de manière à réaliser la poche 40. On introduira un conduit 31 communiquant avec la poche 40 et comportant une valve. Enfin on fera une soudure transversale réalisant un tube transversal 39 communiquant avec toutes les parties 41. Ledit tube transversal 39 comportant une valve 32 permettant d'introduire un gaz, par exemple de l'air dans les espaces 42, 35, 37 et 43. Il est aussi possible de réaliser le dispositif avec quatre feuilles de plastique.The device of this second embodiment is made with two sheets 33 and 44 of plastic material, for example polyethylene / polyamide. We will arrange the two sheets one above the other, and we will make the welds 43, which will define large tubes. Then, we will do the welds 47, so as not to completely separate the parts 42, 35, 37 and 43, the air introduced into one of the parts will pass into the other three parts. Then we will place a valve 38 in each part. The parts 42 will be folded over the parts 43 and the weld 36 will be made (see FIG. 4) so as to make the pocket 40. A conduit 31 communicating with the pocket 40 and including a valve will be introduced. Finally, a transverse weld will be made, making a transverse tube 39 communicating with all the parts 41. Said transverse tube 39 comprising a valve 32 for introducing a gas, for example air into the spaces 42, 35, 37 and 43. It is also possible to make the device with four sheets of plastic.

Lors de l'utilisation d'un dispositif selon l'invention, on remplira d'abord la poche 2 ou 40 avec un liquide, par exemple de l'eau, puis on gonflera les espaces 7 et 8 ou 42, 35, 37,43 avec de l'air. De préférence, la poche 2 ou 40 sera prévue pour recevoir entre 2 et 3 litres de liquide. When using a device according to the invention, the bag 2 or 40 will first be filled with a liquid, for example water, and then the spaces 7 and 8 or 42, 35, 37 will be inflated. 43 with air. Preferably, the bag 2 or 40 will be provided to receive between 2 and 3 liters of liquid.
