Description

Le secteur technique de la présente invention est celuides dispositifs pour alimenter en air un utilisateur.The technical sector of the present invention is those devices for supplying air to a user.

Les dispositifs de plongée sont bien connus etcomprennent généralement une bouteille d'air comprimé àlaquelle est fixé un détendeur primaire suivi en aval d'unembout buccal muni d'un détendeur secondaire pour alimenterun utilisateur en air à la pression ambiante. Un manomètreest fixé au détendeur primaire de manière à ce que leplongeur puisse vérifier à tout moment la pression d'air dansla bouteille et donc la disponibilité d'air respirable.Diving devices are well known and generally include 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 manometer is attached to the primary regulator so that the plunger can check at any time the air pressure in the bottle and thus the availability of breathable air.

Le principal problème qui se pose réside dans la lourdeurdu matériel de plongée d'une part et du remplissage de labouteille qui nécessite impérativement la séparation d'avecle détendeur primaire d'autre part. La bouteille est alorsconnectée directement à un compresseur haute pression deremplissage. Ce matériel est donc inadapté pour des plongéesde loisir d'une durée réduite pour des pratiquantsoccasionnels de la plongée ou pour pénétrer dans desenceintes fermées. C'est le but de la présente invention de fournir unmatériel de plongée léger et peu encombrant. L'invention a donc pour objet un dispositif pouralimenter en air un utilisateur du type comportant unebouteille d'air comprimé, d'un détendeur primaire comportantune sortie haute pression et une sortie moyenne pressionreliée à un embout buccal, caractérisé en ce qu'il comprendun moyen d'adaptation relié à la sortie haute pression pourassurer le remplissage de la bouteille sans sa séparation àl'aide d'une pompe.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 regulator on the other hand. The bottle is then connected directly to a high pressure compressor for filling. This material is therefore unsuitable for recreational dives of limited duration for occasional diving instructors or to enter closed enclosures. It is the object of the present invention to provide lightweight and space-saving diving equipment. The invention therefore relates to a device for supplying air to a user of the type comprisinga bottle of compressed air, a primary pressure regulator comprisinga high pressure outlet and a medium pressure outlet connected to a mouthpiece, characterized in that it comprises a means adapter connected to the high pressure outlet to ensure the filling of the bottle without its separation with the help of a pump.

Selon une caractéristique de l'invention, le moyend'adaptation comprend corps muni d'un premier embout defixation d'un manomètre, d'un second embout et d'un premierconnecteur rapide incorporant un clapet anti-retour.According to a characteristic of the invention, the adaptation means comprises a body provided with a first nozzle for fixing a pressure gauge, a second nozzle and a first quick connector incorporating a nonreturn valve.

Avantageusement, le clapet anti-retour est muni d'unjoint et inséré dans un perçage.Advantageously, the non-return valve is provided with a junction and inserted into a bore.

Selon une autre caractéristique de l'invention, ledispositif comprend un second connecteur rapide pour relierle premier connecteur à la pompe.According to another characteristic of the invention, the device comprises a second quick connector for connecting the first connector to the pump.

Selon encore une autre caractéristique de l'invention, ledispositif comporte un moyen de filtration incorporé entre lesecond 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 unfiltre des particules issues de la pompe, un filtre anti-humidité, un filtre de charbon actif et un filtre anti-graisse.Advantageously, the filtration means comprises a filter particles from the pump, an anti-humidity filter, an activated carbon filter and a grease filter.

Selon encore une autre caractéristique de l'invention, ledispositif comprend un adaptateur pour compenser ladifférence de diamètre entre le corps et le connecteurrapide. L'invention trouve une utilisation particulièrement dansle domaine de la plongée sous-marine ou lors de lacirculation dans une enceinte fermée.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. The invention finds use particularly in the field of scuba diving or when circulating in a closed chamber.

Un tout premier avantage de la présente invention résidedans la simplicité de remplissage de la bouteille d'aircomprimé sans avoir à séparer la bouteille de l'emboutbuccal.A very first advantage of the present invention resides 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 sortiehaute pression pour recharger la bouteille sans aucune autreintervention.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 résidedans l'autonomie de l'utilisateur malgré la faible contenancede la bouteille d'air comprimé.Yet another advantage of the present invention resides in the autonomy of the user despite the low content of the compressed air cylinder.

Un autre avantage encore de l'invention réside dans lerapport faible entre l'encombrement du dispositif et sonautonomie.Another advantage of the invention lies in the weak contribution between the size of the device and its autonomy.

Un autre avantage encore réside dans la légèreté et lacompacité du dispositif, permettant une recharge à toutmoment quel que soit le lieu, sans nécessité d'énergieélectrique et dans l'entretien très simple du matériel. D'autres caractéristiques, avantages et détails del'invention seront mieux compris à la lecture du complémentde description qui va suivre de modes de réalisation donnés àtitre d'exemple en relation avec des dessins sur lesquels : - la figure 1 représente une vue générale du matériel deplongée incluant le dispositif selon l'invention, - la figure 2 représente une vue éclatée des éléments constituant le moyen d'adaptation, - la figure 3 représente une vue du moyen d'adaptationassemblée, - la figure 4 est une vue montrant l'insertion du moyende filtration, - la figure 5 est une coupe du moyen de filtration, et - la figure 6 est une coupe du connecteur rapide.Another advantage lies in the lightness and leniency 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 the equipment.

On voit que lemanomètre 8 est vissé sur l'embout 10 et le réducteur 14 surl'embout 13. Le réducteur 14 est prolongé par le connecteurmâle 12. Ainsi, ce connecteur 12 est destiné à recevoir unconnecteur femelle afin de relier la pompe à l'ensemble afin de réalimenter la bouteille 1 en air comprimé.In FIG. 3, the adaptation means 7 is shown in the assembled position in order to allow air circulation from the pump to the bottle 1. It can be seen that the meter 8 is screwed onto the nozzle 10 and the gearbox 14 on the Tip 13. The gearbox 14 is extended by the male connector 12. Thus, this connector 12 is intended to receive a female connector to connect the pump to the assembly in order to supply the bottle 1 with compressed air.

Sur la figure 4, on a représenté les éléments deconnexion de manière étanche entre la pompe 25 et leconnecteur 12. Pour cela, un filtre 16 vissé à une extrémitédans l'embout de la pompe et à l'autre extrémité à unconnecteur femelle 17. Ce connecteur femelle 17 est du type àencliquetage rapide dans le connecteur mâle 12 afin depermettre une liaison rapide avec la pompe 25 et augmenterainsi la disponibilité de la bouteille 1. Le filtre 16comprend une enveloppe métallique 18 munie d'un filetage mâleaux deux extrémités.In FIG. 4, the sealing elements are shown in leaktight manner 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 into a female connector 17. The female connector 17 is of the fast-snap type in the male connector 12 in order to make 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 lastructure interne du filtre 16 prévue pour le dispositifselon l'invention. Dans l'enveloppe 18, on dispose d'abord unfiltre 19 pour éliminer les particules issues de l'aircomprimé engendrées par la pompe 25, puis un filtre 20 del'humidité résiduelle de l'air comprimé, puis un filtre 21complété par un filtre 22 anti-graisse. Le filtre 20 est parexemple constitué d'un gel de silice, le filtre 21 du charbonactif 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 casing 18, there is first a filter 19 to remove the particles from the compressed air generated by the pump 25, then a residual moisture filter 20 of compressed air, and a filter 21completed by a filter 22 grease. The filter 20 is for example made 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 connecteurmâle 12 comportant un perçage 29 de forme tronconique àl'intérieur duquel est prévu un clapet anti-retour 27. Ceclapet de forme cylindrique est équipé d'un joint torique 28destiné à obstruer de manière étanche le perçage 29 lorsquel'utilisateur respire. La pression régnant dans la bouteille1 entraînera vers la droite dans le plan de la figure leclapet 27. Lors du gonflage à l'aide de la pompe, le clapet27 est entraîné vers la gauche afin de libérer le perçage 29et de permettre ainsi le remplissage de la bouteille 1.In Figure 6, there is shown in section the male connector 12 having a frustoconical bore 29 within which there is provided a nonreturn valve 27. Ceclapet cylindrical shape is equipped with an O-ring 28 for sealing tightly piercing 29 when the user is breathing. The pressure prevailing in the bottle 1 will lead to the right in the plane of Figure leclapet 27. When inflating with the pump, the valve 27 is driven to the left to release the bore 29 and thus allow the filling of the bottle 1.

Le dispositif selon l'invention est donc très léger etpermet à l'utilisateur pratiquant d'effectuer une plongée entemps limité mais avec le minimum de contrainte. Ledispositif peut être directement utilisé en bouche sans autreattache que l'embout buccal 6 ou bien être fixé au niveau dubuste par un harnais. Dans ce cas, la bouteille 1 peut êtreplacée 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 limited time but with the minimum of constraint. The device can be directly used in the mouth without any other than the mouthpiece 6 or be fixed at the level of bust by a harness. In this case, the 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 unerecharge rapide de la bouteille 1 en air haute pression àtravers la sortie haute pression 4 du détendeur 3.Contrairement aux réalisations antérieures où la sortie hautepression servait uniquement à brancher un manomètre,l'invention permet de manière pratique de rechargerrapidement la bouteille par cette sortie. Le sens decirculation du flux d'air comprimé est donc inversé lors dela recharge de la bouteille.The low volume of air in the bottle 1 does not constitute a handicap because the system according to the invention makes it possible to rapidly discharge the bottle 1 in high pressure air through the high pressure outlet 4 of the pressure reducer 3. Unlike previous embodiments where the outlet highpressure was only used to connect a pressure gauge, the invention allows a practical way to quickly refill the bottle through this outlet. The flow direction of the compressed air flow is reversed when the bottle is refilled.

On utilise de manière nouvelle la sortie haute pressiondu détendeur. L'invention permet également l'incorporation du manomètrehaute pression 8 pour que l'utilisateur puisse vérifier àtout moment le volume d'air disponible dans la bouteille 1.Ainsi, l'invention permet d'assurer une bonne autonomie del'utilisateur en permettant une recharge rapide de labouteille 1 en évitant les opérations classiques consistant àenlever le premier étage en dévissant le robinet pourconnecter le compresseur au robinet et recharger la bouteilleen air comprimé.The high pressure outlet of the expander is used in a new way. The invention also allows the incorporation of the high pressure manometer 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 bottle 1 by avoiding the usual operations of removing the first stage by unscrewing the tap to connect the compressor to the tap and reload the bottle in compressed air.
