Description

DISPOSITIF POUR ALIMENTER EN AIR UN UTILISATEUR  DEVICE FOR SUPPLYING A USER TO AIR
Le secteur technique de la présente invention est celui des dispositifs pour alimenter en air un utilisateur. The technical sector of the present invention is that of the devices for supplying a user with air.
Les dispositifs de plongée sont bien connus et comprennent généralement une bouteille d'air comprimé à laquelle est fixé un détendeur primaire suivi en aval d'un embout buccal muni d'un détendeur secondaire pour alimenter un utilisateur en air à la pression ambiante. Un manomètre est fixé au détendeur primaire de manière à ce que le plongeur puisse vérifier à tout moment la pression d'air dans la bouteille et donc la disponibilité d'air respirable.  The diving devices are well known and generally comprise a compressed air cylinder to which is attached a primary expander followed downstream of a mouthpiece provided with a secondary expander for supplying a user with air at ambient pressure. A pressure gauge is attached to the primary regulator so that the diver can check at any time the air pressure in the bottle and therefore the availability of breathable air.
Le principal problème qui se pose réside dans la lourdeur du matériel de plongée d'une part et du remplissage de la bouteille qui nécessite impérativement la séparation d'avec le détendeur primaire d'autre part. La bouteille est alors connectée directement à un compresseur haute pression de remplissage. Ce matériel est donc inadapté pour des plongées de loisir d'une durée réduite pour des pratiquants occasionnels de la plongée ou pour pénétrer dans des enceintes fermées.  The main problem is the heavy dive equipment on the one hand and the filling of the bottle which necessarily requires separation from the primary pressure reducer on the other hand. The bottle is then connected directly to a high-pressure filling compressor. This material is therefore unsuitable for recreational dives of limited duration for occasional diving practitioners or to enter closed enclosures.
C'est le but de la présente invention de fournir un matériel de plongée léger et peu encombrant.  It is the object of the present invention to provide lightweight and compact dive equipment.
L' invention a donc pour objet un dispositif pour alimenter en air un utilisateur du type comportant une bouteille d'air comprimé, d'un détendeur primaire comportant une sortie haute pression et une sortie moyenne pression reliée à un embout buccal, caractérisé en ce qu'il comprend un moyen d'adaptation relié à la sortie haute pression pour assurer le remplissage de la bouteille sans sa séparation à l'aide d'une pompe.  The invention therefore relates to a device for supplying air to a user of the type comprising a compressed air cylinder, a primary expander having a high pressure outlet and a medium pressure outlet connected to a mouthpiece, characterized in that it comprises an adaptation means connected to the high-pressure outlet for filling the bottle without its separation by means of a pump.
Selon une caractéristique de l'invention, le moyen d'adaptation comprend corps muni d'un premier embout de fixation d'un manomètre, d'un second embout et d'un premier connecteur rapide incorporant un clapet anti-retour.  According to a characteristic of the invention, the adaptation means comprises a body provided with a first attachment end of a pressure gauge, a second endpiece and a first quick connector incorporating a nonreturn valve.
Avantageusement, le clapet anti-retour est muni d'un joint et inséré dans un perçage.  Advantageously, the non-return valve is provided with a seal and inserted into a bore.
Selon une autre caractéristique de l'invention, le dispositif comprend un second connecteur rapide pour relier le premier connecteur à la pompe. According to another characteristic of the invention, the device includes a second quick connector for connecting the first connector to the pump.
Selon encore une autre caractéristique de l'invention, le dispositif comporte un moyen de filtration incorporé entre le second connecteur et la pompe.  According to yet another characteristic of the invention, the device comprises a filtration means incorporated between the second connector and the pump.
Avantageusement, le moyen de filtration comprend un filtre des particules issues de la pompe, un filtre anti¬ humidité, un filtre de charbon actif et un filtre anti¬ graisse . Advantageously, the filtering means comprises a filter particles from the pump, an anti ¬ moisture filter, an active carbon filter and a filter anti ¬ fat.
Selon encore une autre caractéristique de l'invention, le dispositif comprend un adaptateur pour compenser la différence de diamètre entre le corps et le connecteur rapide .  According to yet another characteristic of the invention, the device comprises an adapter for compensating for the difference in diameter between the body and the quick connector.
L' invention trouve une utilisation particulièrement dans le domaine de la plongée sous-marine ou lors de la circulation dans une enceinte fermée.  The invention finds use particularly in the field of diving or when circulating in a closed enclosure.
Un tout premier avantage de la présente invention réside dans la simplicité de remplissage de la bouteille d'air comprimé sans avoir à séparer la bouteille de l'embout buccal .  A first advantage of the present invention lies in the simplicity of filling the compressed air cylinder without having to separate the bottle from the mouthpiece.
Un autre avantage réside dans l'utilisation de la sortie haute pression pour recharger la bouteille sans aucune autre intervention .  Another advantage is the use of the high-pressure outlet to refill the bottle without any further intervention.
Un autre avantage encore de la présente invention réside dans l'autonomie de l'utilisateur malgré la faible contenance de la bouteille d'air comprimé.  Another advantage of the present invention lies in the autonomy of the user despite the small capacity of the compressed air cylinder.
Un autre avantage encore de l'invention réside dans le rapport faible entre l'encombrement du dispositif et son autonomie .  Another advantage of the invention lies in the low ratio between the size of the device and its autonomy.
Un autre avantage encore réside dans la légèreté et la compacité du dispositif, permettant une recharge à tout moment quel que soit le lieu, sans nécessité d'énergie électrique et dans l'entretien très simple du matériel.  Another advantage lies in the lightness and compactness of the device, allowing recharging at any time regardless of the location, without the need for electrical energy and in the very simple maintenance of equipment.
D'autres caractéristiques, avantages et détails de l'invention seront mieux compris à la lecture du complément de description qui va suivre de modes de réalisation donnés à titre d'exemple en relation avec des dessins sur lesquels :  Other features, advantages and details of the invention will be better understood on reading the additional description which will follow of embodiments given by way of example in relation to drawings in which:

Un matériel de plongée ou d'inspection d'enceintes fermée comporte en général une bouteille 1 d'air comprimé munie d'un robinet 2, auquel est fixé un détendeur 3 haute pression. Ce détenteur 3 comporte généralement plusieurs sorties dont une sortie haute pression 4 et au moins une sortie 5 moyenne pression. La sortie moyenne pression est reliée classiquement à un embout buccal 6 à l'aide d'un flexible 7a.  Closed diving or enclosure inspection equipment generally comprises a compressed air cylinder 1 having a valve 2, to which is attached a high pressure regulator 3. This holder 3 generally comprises several outputs including a high pressure output 4 and at least one output 5 medium pressure. The medium pressure outlet is conventionally connected to a mouthpiece 6 using a hose 7a.
Par haute pression, on entend une pression de l'ordre de 200.105 Pa et par moyenne pression une pression de l'ordre de 8, 5.105 Pa. By high pressure means a pressure of the order of 200.10 5 Pa and by medium pressure a pressure of the order of 8, 5.10 5 Pa.
Toutefois, la figure 1 illustre une bouteille 1 de faible contenance procurant une autonomie de l'ordre d'un quart d'heure contrairement aux bouteilles classiques autorisant des heures de plongée. Sur la figure, on a aussi incorporé dans le dispositif 100 le moyen d'adaptation 7b selon l'invention, sur lequel est fixé un manomètre 8.  However, Figure 1 illustrates a bottle 1 of low capacity providing a range of about fifteen minutes unlike conventional bottles allowing hours of diving. In the figure, there is also incorporated in the device 100 the adaptation means 7b according to the invention, on which is fixed a manometer 8.
Sur la figure, on a représenté en vue éclatée le moyen d'adaptation selon l'invention qui comprend un corps 9 muni d'un premier embout 10 de fixation du manomètre 8, d'un second embout 11 et d'un premier connecteur rapide 12 incorporant un clapet anti-retour et apte à être fixé dans le raccord 13 au moyen d'un réducteur 14. Sur la figure, on voit que le manomètre 8 est muni d'un joint 15 pour assurer l'étanchéité vis-à-vis du corps 9.  In the figure, there is shown in exploded view the adaptation means according to the invention which comprises a body 9 provided with a first attachment piece 10 for fixing the pressure gauge 8, a second endpiece 11 and a first quick connector 12 incorporating a non-return valve and adapted to be fixed in the coupling 13 by means of a gearbox 14. In the figure, it can be seen that the pressure gauge 8 is provided with a seal 15 to seal against body screw 9.
Sur la figure 3, on a représenté le moyen d'adaptation 7b en position assemblée afin de permettre la circulation d'air venant de la pompe vers la bouteille 1. On voit que le manomètre 8 est vissé sur l'embout 10 et le réducteur 14 sur l'embout 13. Le réducteur 14 est prolongé par le connecteur mâle 12. Ainsi, ce connecteur 12 est destiné à recevoir un connecteur femelle afin de relier la pompe à l'ensemble afin de réalimenter la bouteille 1 en air comprimé. In FIG. 3, the adaptation means 7b is shown in the assembled position in order to allow air to flow from the pump to the bottle 1. It can be seen that the pressure gauge 8 is screwed onto the nozzle 10 and the reducer 14 on the tip 13. The reducer 14 is extended by the connector Thus, this connector 12 is intended to receive a female connector in order to connect the pump to the assembly in order to refuel the bottle 1 with compressed air.
Sur la figure 4, on a représenté les éléments de connexion de manière étanche entre la pompe 25 et le connecteur 12. Pour cela, un filtre 16 vissé à une extrémité dans l'embout de la pompe et à l'autre extrémité à un connecteur femelle 17. Ce connecteur femelle 17 est du type à encliquetage rapide dans le connecteur mâle 12 afin de permettre une liaison rapide avec la pompe 25 et augmenter ainsi la disponibilité de la bouteille 1. Le filtre 16 comprend une enveloppe métallique 18 munie d'un filetage mâle aux deux extrémités.  FIG. 4 shows the connection elements sealingly between the pump 25 and the connector 12. For this, a filter 16 screwed at one end into the end of the pump and at the other end to a connector female 17. This female connector 17 is of the snap type in the male connector 12 to allow a quick connection with the pump 25 and thus increase the availability of the bottle 1. The filter 16 comprises a metal casing 18 provided with a male thread at both ends.
La coupe représentée sur la figure 5 illustre la structure interne du filtre 16 prévue pour le dispositif selon l'invention. Dans l'enveloppe 18, on dispose d'abord un filtre 19 pour éliminer les particules issues de l'air comprimé engendrées par la pompe 25, puis un filtre 20 de l'humidité résiduelle de l'air comprimé, puis un filtre 21 complété par un filtre 22 anti-graisse. Le filtre 20 est par exemple constitué d'un gel de silice, le filtre 21 du charbon actif et le filtre 22 une lame de polyester.  The section shown in FIG. 5 illustrates the internal structure of the filter 16 provided for the device according to the invention. In the envelope 18, there is first a filter 19 to remove the particles from the compressed air generated by the pump 25, then a filter 20 of the residual moisture of the compressed air, then a filter 21 completed by a grease filter 22. The filter 20 consists for example of a silica gel, the filter 21 of the activated carbon and the filter 22 a polyester strip.
Sur la figure 6, on a représenté en coupe le connecteur mâle 12 comportant un perçage 29 de forme tronconique à l'intérieur duquel est prévu un clapet anti-retour 27. Ce clapet de forme cylindrique est équipé d'un joint torique 28 destiné à obstruer de manière étanche le perçage 29 lorsque l'utilisateur respire. La pression régnant dans la bouteille 1 entraînera vers la droite dans le plan de la figure le clapet 27. Lors du gonflage à l'aide de la pompe, le clapet 27 est entraîné vers la gauche afin de libérer le perçage 29 et de permettre ainsi le remplissage de la bouteille 1.  FIG. 6 shows in section the male connector 12 having a frustoconical shaped bore 29 inside which a nonreturn valve 27 is provided. This cylindrical valve is equipped with an O-ring 28 for sealing the piercing 29 when the user breathes. The pressure prevailing in the bottle 1 will cause the valve 27 to turn to the right in the plane of the figure. During inflation by means of the pump, the valve 27 is driven to the left in order to release the piercing 29 and thus to allow the filling of the bottle 1.
Le dispositif selon l'invention est donc très léger et permet à l'utilisateur pratiquant d'effectuer une plongée en temps limité mais avec le minimum de contrainte. Le dispositif peut être directement utilisé en bouche sans autre attache que l'embout buccal 6 ou bien être fixé au niveau du buste par un harnais. Dans ce cas, la bouteille 1 peut être placée soit contre le buste soit dans le dos. The device according to the invention is therefore very light and allows the practicing user to perform a dive in limited time but with the minimum of constraint. The device can be directly used in the mouth without any other attachment than the mouthpiece 6 or be fixed at the bust by a harness. In this case, bottle 1 can be placed either against the bust or in the back.
Le faible volume d'air de la bouteille 1 ne constitue pas un handicap car le système selon l'invention permet une recharge rapide de la bouteille 1 en air haute pression à travers la sortie haute pression 4 du détendeur 3. Contrairement aux réalisations antérieures où la sortie haute pression servait uniquement à brancher un manomètre, l'invention permet de manière pratique de recharger rapidement la bouteille par cette sortie. Le sens de circulation du flux d'air comprimé est donc inversé lors de la recharge de la bouteille.  The low volume of air in the bottle 1 is not a handicap because the system according to the invention allows a quick refill of the bottle 1 in high pressure air through the high pressure outlet 4 of the regulator 3. Unlike the previous achievements where the high pressure outlet was only used to connect a manometer, the invention allows a practical way to quickly recharge the bottle through this outlet. The flow direction of the compressed air flow is therefore reversed when the bottle is refilled.
On utilise de manière nouvelle la sortie haute pression du détendeur.  The high pressure outlet of the expander is used again.
L'invention permet également l'incorporation du manomètre haute pression 8 pour que l'utilisateur puisse vérifier à tout moment le volume d'air disponible dans la bouteille 1. Ainsi, l'invention permet d'assurer une bonne autonomie de l'utilisateur en permettant une recharge rapide de la bouteille 1 en évitant les opérations classiques consistant à enlever le premier étage en dévissant le robinet pour connecter le compresseur au robinet et recharger la bouteille en air comprimé.  The invention also allows the incorporation of the high pressure gauge 8 so that the user can check at any time the volume of air available in the bottle 1. Thus, the invention ensures a good autonomy of the user by allowing a quick refill of the bottle 1 by avoiding the conventional operations of removing the first stage by unscrewing the tap to connect the compressor to the tap and refill the bottle with compressed air.
