Abstract
Description
La présente invention concerne d'une façon générale les conteneurs utilisés pour le transport de matériels fragiles tels que les matériels électroniques, électromécaniques, optiques ou autres utilisés par exemple dans les domaines aéronautique, spatial, medical etc.. et elle est plus patriculièrement relative à un dispositif d'équilibrage de la pression interne de ces conteneurs avec la pression atmosphérique.The present invention relates generally to the containers used for the transport of fragile materials such as electronic, electromechanical, optical or other materials used for example in the aeronautical, space, medical fields etc. and it is more specifically related to a device for balancing the internal pressure of these containers with atmospheric pressure.
Ces conteneurs doivent assurer une protection efficace contre les risques de manutention (chocs, chutes) et doivent être etanches aux eaux de pluie et de ruissellement. Ce dernier imperatif implique une construction presentant une ètancheite à peu prés parfaite à l'air.These containers must provide effective protection against handling risks (shocks, falls) and must be waterproof against rain and runoff. This last imperative implies a construction presenting an airtightness almost perfect in air.
Cette etanchèite à l'air entraîne des inconvénients bien connus qui sont dûs aux variations des pressions internes et externes au conteneur. Ces variations de pression peuvent avoir deux causes principales dont l'une est la difference de température entre l'intérieur et l'exterieur du conteneur soumis aux variations de la temperature ambiante et dont l'autre est dûe par exemple aux variations d'altitudes lors des transports aeriens en avion ou en hélicoptère pressurise ou non. De plus ces deux causes peuvent s'additionner dans certains cas.This airtightness involves well-known drawbacks which are due to variations in the pressures inside and outside the container. These pressure variations can have two main causes, one of which is the temperature difference between the interior and the exterior of the container subjected to variations in ambient temperature and the other of which is due, for example, to variations in altitudes during air transport by plane or by helicopter, pressurized or not. In addition, these two causes can add up in certain cases.
La différence de pression peut atteindre des valeurs telles que les déformations du conteneur risquent d'être nuisibles aux matériels qu'il renferme.The pressure difference can reach values such that the deformations of the container may be harmful to the materials it contains.
Pour remédier à ces inconvenients on a réalisé les conteneurs en un matériau suffisamment résistant, ce qui entraîne une augmentation de poids coûteuse en cas de transport aérien en particulier.To remedy these drawbacks, the containers have been made of a sufficiently resistant material, which leads to an expensive weight increase in the case of air transport in particular.
On a decrit au brevet americain n° 2.113.454 un dispositif de soupape de mise à l'air libre à fermeture automatique lorsque le conteneur se trouve dans une position autre que sa position normale. Ce dispositif n'assure pas l'étanchéite aux eaux de ruissellement lorsque le conteneur se trouve en position verticale.American patent No. 2,113,454 has described a self-closing vent valve device when the container is in a position other than its normal position. This device does not provide watertightness when the container is in an upright position.
On a décrit au brevet américain n° 2.939.603 un dispositif d'équilibrage de pression constitué par un robinet de décharge actionné au moyen d'une vis. Ce dispositif nécessite de serrer ou desserrer la vis; lorsque la vis est serrée elle empêche l'équilibrage de la pression et lorsqu'elle est desserrée le conteneur n'est plus étanche aux eaux de pluie et de ruissellement.There has been described in US Patent No. 2,939,603 a pressure balancing device consisting of a relief valve actuated by means of a screw. This device requires tightening or loosening the screw; when the screw is tightened it prevents pressure balancing and when it is loose the container is no longer waterproof against rain and runoff.
Le brevet français n° 2.369.175 et son addition n° 2.436.718 décrivent un agencement de chambres à vide dans un conteneur, destinées à la ventilation des parois latérales. L'agencement de ces chambres qui comportent des chicanes n'empêche pas la pénétration des eaux de pluie et/ou de ruissellement dans les différentes positions du conteneur et est en plus de construction compliquée et par suite coûteuse.French patent no. 2,369,175 and its addition no. 2,436,718 describe an arrangement of vacuum chambers in a container, intended for the ventilation of the side walls. The arrangement of these chambers which include baffles does not prevent the penetration of rainwater and / or runoff into the various positions of the container and is in addition complicated and consequently expensive to construct.
Il résulte de ce qui précède que les dispositifs de la technique antérieure ne permettent pas de résoudre à la fois les problémes d'étanchéité à l'eau et d'équilibrage de la pression d'une façon satisfaisante, bien qu'il existe des soupapes dites d'équipression qui sont des matériels souvent complexes nécessitant un entretien périodique pour garantir leur bon fonctionnement.It follows from the above that the devices of the prior art do not make it possible to solve both the problems of watertightness and of pressure balancing in a satisfactory manner, although there are valves say of equipression which are often complex materials requiring periodic maintenance to guarantee their proper functioning.
L'invention a pour but de remédier à ces inconvenients en réalisant un dispositif d'équilibrage de pression pour conteneur, notamment pour le transport des matériels fragiles, qui assure de façon permanente l'équilibrage de la pression intérieure du conteneur avec la pression atmosphérique tout en réalisant en même temps une barrière efficace à la pénétration des eaux de pluie et/ou de ruissellement.The object of the invention is to remedy these drawbacks by producing a pressure balancing device for a container, in particular for transporting fragile materials, which permanently balances the internal pressure of the container with atmospheric pressure while at the same time creating an effective barrier to the penetration of rainwater and / or runoff.
L'invention a pour objet à cet effet un dispositif d'équilibrage de pression étanche aux eaux de pluie ou de ruissellement pour conteneur, caractérisé en ce qu'il comprend une chambre ayant une paroi externe, et une paroi interne la séparant du conteneur, ladite chambre communiquant d'une part avec l'extérieur par au moins un orifice ménagé dans ladite parci externe et d'autre part avec l'intérieur du conteneur par un tube s'étendant à travers ladite paroi interne et faisant saillie dans ladite chambre. la forme de ladite paroi interne et la position de l'orifice de la paroi externe étant telles que dans une position quelconque du conteneur l'orifice ou une partie de celui-ci soit situé à un niveau inférieur à celui de l'extrémité dudit tube dans la chambre.The subject of the invention is to this end a device for balancing pressure sealed against rainwater or runoff for container, characterized in that it comprises a chamber having an external wall, and an internal wall separating it from the container, said chamber communicating on the one hand with the outside by at least one orifice formed in said external area and on the other hand with the inside of the container by a tube extending through said internal wall and projecting into said chamber. the shape of said internal wall and the position of the orifice of the external wall being such that in any position of the container the orifice or part of it is located at a level below that of the end of said tube in the bedroom.
Dans la suite de la présente description le terme "orifice" doit être entendu comme désignant une ouverture de forme quelconque.In the remainder of this description, the term "orifice" should be understood as designating an opening of any shape.
Grâce à cet agencement, un liquide pouvant avoir pénétré dans la chambre ne peut pénétrer dans le conteneur.Thanks to this arrangement, a liquid which may have entered the chamber cannot enter the container.
Suivant une autre caractéristique de l'invention, le dispositif comporte une plaque déflectrice espacée de ladite paroi externe et qui la recouvre en ménageant avec elle des interstices en chicanes avec les orifices.According to another characteristic of the invention, the device comprises a deflecting plate spaced from said external wall and which covers it by providing with it interstices in baffles with the orifices.
Suivant un mode de réalisation préféré de l'invention, ladite paroi externe est constituée par une partie de la paroi du conteneur.According to a preferred embodiment of the invention, said external wall is formed by a part of the wall of the container.
Ladite paroi interne peut présenter une forme quelconque. Selon un mode préféré de réalisation de l'invention, elle présente la forme d'un quart de cylindre. Selon un autre mode de réalisation, elle présente la forme d'un quart de sphere.Said internal wall can have any shape. According to a preferred embodiment of the invention, it has the shape of a quarter cylinder. According to another embodiment, it has the shape of a quarter of a sphere.
D'autres caractéristiques et avantages de l'invention apparaîtront au cours de la description qui va suivre faite en se référant au dessin annexé donné uniquement à titre d'exemple et dans lequel:
- La figure 1 est une vue partielle en section d'un conteneur utilisé pour le transport par voie aerienne de matériels fragiles et comportant un dispositif suivant l'invention.
- La figure 2 est une vue en plan de dessus avec arrachement partiel correspondant à la vue de la figure 1.
- Figure 1 is a partial sectional view of a container used for the transport by air of fragile materials and comprising a device according to the invention.
- FIG. 2 is a top plan view with partial cutaway corresponding to the view in FIG. 1.
En se référant au dessin, on a représenté une partie d'un conteneur ayant dans son ensemble une forme à peu prés parallélépipédique, de construction connue, par exemple en une résine armée de fibres de verre, comprenant une partie inférieure 1 et une partie supérieure 2 maintenues assemblées par des moyens classiques (non représentés) comportant un fond 3, et une paroi supérieure 4 formant couvercle, des moyens d'étanchéité 5 à la jonction du fond et du couvercle 1 et 2, des organes de manutention et d'arrimage 6 et des pieds 7 ou autres formations analogues classiques sur les conteneurs de transport.Referring to the drawing, there is shown a part of a container having as a whole a roughly parallelepiped shape, of known construction, for example of a resin reinforced with glass fibers, comprising a
Le conteneur représenté au dessin comporte un dispositif d'équilibrage de pression et d'étanchéité aux eaux de pluie et de ruissellement, qui est désigné dans son ensemble par la référence 8. Ce dispositif 8 comprend une chambre 9 ayant une paroi extérieure constituée par une partie 10 de la paroi du couvercle 4, cette partie 10 étant légérement en retrait par rapport au reste de la paroi du couvercle, délimitant ainsi une cavité peu profonde 11, cette partie de la paroi du couvercle étant située à cheval sur deux côtés adjacents de la paroi du couvercle, de part et d'autre de l'arete supérieure et à peu pres à égale distance entre les deux angles du couvercle du conteneur comme représenté à la figure 2.The container shown in the drawing comprises a device for balancing pressure and sealing against rainwater and runoff, which is generally designated by the
La chambre 9 comporte une paroi interne rapportée 12 qui, suivant l'exemple représenté, présente la forme d'un quart de sphere.The
La paroi interne 12 isole la chambre 9 du volume intérieur du conteneur et est traversée par un tube rayonnant 13 qui fait communiquer le volume intérieur du conteneur avec le volume intérieur de la chambre 9.The
Le tube 13 est fixé dans un bossage 14 de la paroi et s'etend en saillie à l'intérieur de la chambre:The
La paroi externe 10 de la chambre 9 est percée d'orifices 16, 1θa, 16b, 16c, dont deux seulement sont visibles dans la coupe de la figure 1 et qui apparaissent à la figure 2.The
L'extrémité du tube 15 est située:
- - d'une part au-dessus du ou des plans d'eau pouvant éventuellement s'accumuler dans la chambre quelle que soit sa position,
- - d'autre part, à une distance suffisante des parois de la chambre pour éviter la pénétration de liquide
dans ledit tube d'aération 13, due au front d'une vague possible de liquide.The end of the
- - on the one hand above the body or bodies of water which may possibly accumulate in the room whatever its position,
- - on the other hand, at a sufficient distance from the walls of the chamber to prevent the penetration of liquid
in said
En se référant à la figure 2 on voit qu'un orifice 16 est prévu au milieu du demi-cercle constitué par la paroi 12, considérée en plan, un autre orifice 16a étant prévu dans la partie supérieure de la paroi externe 10 au voisinage de l'angle formé par celle-ci suivant l'aréte du conteneur, un troisième orifice 16b étant prévu dans la partie latérale de la paroi externe 10, diamétralement opposé par rapport à l'orifice 16a tandis qu'un quatrième orifice 16c est symétrique de l'orifice 16 par rapport à l'aréte latérale de la paroi externe 10.Referring to FIG. 2, it can be seen that an
On comprend que gràce à la forme en quart de sphère de la paroi interne 12 et à l'emplacement des orifices 16, 16a, 16b, 16c, un liquide se trouvant dans la chambre 9 ne peut pénétrer dans le conteneur, quelle que soit sa position. En outre l'extrémité interne 15 du tube 13 dans la chambre 9 se trouve toujours située au-dessus de l'un des orifices 16, 16a, 16b, 16c, quelle que soit la position du conteneur. On comprend ainsi que de l'eau de pluie ou de ruissellement pouvant avoir pénétré dans la chambre 9 ne peut jamais atteindre un niveau suffisant dans celle-ci pour pénétrer à l'intérieur du conteneur par l'intermédiaire de l'extrémité 15 du tube 13.We understand that thanks to the quarter-sphere shape of the
Pour limiter encore les possibilités de pénétration des eaux de pluie ou de ruissellement dans la chambre il est avantageusement prévu suivant une autre caractéristique de l'invention une paroi déflectrice 18 qui recouvre ta paroi externe 10 en étant espacée de celle-ci comme représenté à la figure 1, cette paroi déflectrice 18 ayant dans son ensemble la forme d'une équerre dont les extrémités des ailes sont arrondies et qui est fixée par le bord interne de ses ailes sur la périphérie 19 de la cavité 11 par l'intermédiaire d'entretoises 20 au moyen par exemple de rivets ou de points de soudure 21.To further limit the possibilities of penetration of rainwater or runoff into the chamber, it is advantageously provided according to another characteristic of the invention, a
On comprend que gràce à cet agencement la paroi déflectrice 18 délimite avec la périphérie 19 de la cavité 11 formée dans la paroi supérieure 4 du conteneur un intervalle dont la hauteur correspond à l'épaisseur des entretoises 20, qui permet ainsi le libre passage de l'air, tandis que les intervalles entre les entretoises 20 sont contrariés par rapport aux orifices 16, 16a, 16b, 16c de telle sorte que les eaux de pluie ou de ruissellement pouvant pénétrer à l'intérieur de la chambre 9 sont limitées aux quantités pouvant parvenir aux orifices 16, 16a, 16b, 16c, ces quantites extrêmement limitées s'écoulant immédiatement par ces orifices sans jamais atteindre le niveau fixe par l'extremite 15 du tube 13.We understand that thanks to this arrangement the deflecting
On comprend bien entendu que la paroi interne 12 décrite comme présentant la forme d'un quart de sphère, pourrait avoir une forme différente, par exemple formée de portions de plan formant entre elles des angles diédres délimitant par exemple une portion d'un polyèdre (y compris un cylindre).It is understood of course that the
On comprend également qu'il peut être prévu, si on le désire, plusieurs chambres 9 situées en des points quelconques de la paroi du conteneur de façon que la paroi externe 10 chevauche au moins une aréte de celui-ci, lesdites chambres 9 assurant ainsi non seulement l'équilibrage de pression des conteneurs, mais aussi, en combinaison entre elles, une aération et/ou ventilation de l'intérieur dudit conteneur ou enceinte.It is also understood that there may be provided, if desired,
On comprend enfin que la paroi déflectrice 18 constitue une protection pour la paroi externe 10 de la chambre de telle sorte qu'en cas de choc consécutif à une manutention brutale du conteneur cette paroi 10 soit protégée de tout risque de rupture.It is finally understood that the
L'invention fournit ainsi un dispositif d'équilibrage de pression parfaitement étanche à la pénétration des eaux de pluie ou de ruissellement et qui est particuliérement avantageux pour être utilisé sur les conteneurs de transport de materiels fragiles qui peuvent ainsi etre emmagasines dans un sens quelconque sans respecter une face d'appui au sol prédéterminée et permettant également le transport aérien des conteneurs sans protection particuliére en ce qui concerne les variations de pression. En outre le matériel emballé dans le conteneur muni du dispositif suivant l'invention se trouve toujours protégé des eaux de pluie ou de ruissellement ce qui rend le conteneur apte au transport maritime même à l'exterieur des cales. Des essais effectués sous pluie artificielle et en procédant à des arrosages abondants dans toutes les positions du conteneur ont démontré un écoulement parfait de l'eau dans la chambre 9 d'équilibrage de pression sans que se produise aucune pénétration du liquide à l'interieur du conteneur par le tube 13.The invention thus provides a pressure-tightening device that is perfectly sealed against the penetration of rainwater or runoff and which is particularly advantageous for being used on containers for transporting fragile materials which can thus be stored in any direction without respecting a predetermined bearing face on the ground and also allowing air transport containers without special protection with regard to pressure variations. In addition, the material packed in the container fitted with the device according to the invention is always protected from rain or runoff water, which makes the container suitable for maritime transport even outside the holds. Tests carried out in artificial rain and using abundant watering in all the container positions have shown a perfect flow of water in the
Dans une variante non représentée, la paroi 10 pourrait être inexistante et ainsi la chambre 9 serait délimitée par la paroi 12 et le déflecteur 18, l'intervalle entre le déflecteur 18 et la paroi 4 fractionné par les entretoises 20 délimitant des sections de passage d'eau ou d'air garantissant les fonctions des trous ménagés dans la paroi 10 de la solution de base.In a variant not shown, the
