Definitions

  • the present invention relates to the field of diving masks, including masks used for underwater hiking, also called PMT (Palmes-Mask-Tuba), in English “snorkeling”.
  • PMT Palmes-Mask-Tuba
  • the underwater hiker is equipped with a mask for vision, and a snorkel for breathing.
  • the tuba consists of a tube whose lower end is provided with a mouth portion which is housed in the mouth of the user, and an upper end for both the admission of fresh air and Exhaled air exhaust.
  • the appearance of mist is due to the fact that the user's nose opens into the vision chamber located between the visor and the eyes of the user.

  • the exhaled air circulates in the skirt constituted by a flexible hollow seal which adheres between the mask and the face.
  • Such a mask however, has a disadvantage. If the user uses the mask attachment system too hard, the flexible hollow seal will crash against the face, which will cause the obstruction of the line through which the expired airflow flows. On the other hand, if the user does not sufficiently serve the fixing system, there will not be a perfect seal between the face and the skirt, as a result of which water may penetrate inside the chambers. lower or higher, which is not desirable.
  • An object of the invention is to provide a diving mask remedies including the aforementioned drawbacks.

  • the frame comprises at least a first lateral connection engaged in the upper end of the first sleeve.
  • this first lateral connection extends towards the lower part of the mask.
  • This first lateral connection is preferably curved towards the inside of the mask.
  • the upper end of the first sleeve has a lower cross section smaller than the cross section of the first side connector.
  • the upper end of the first sleeve is flush with a lateral side of the frame, which makes it possible to obtain a frame having a lateral side devoid of roughness. Thanks to this arrangement, the sleeve does not provide a plug, and therefore does not risk being inadvertently disconnected from the first side connector.

Description

Arrière-plan de l'inventionBackground of the invention

La présente invention concerne le domaine des masques de plongée, et notamment les masques utilisés pour la randonnée subaquatique, également appelée PMT (Palmes-Masque-Tuba), en anglais « snorkeling ».The present invention relates to the field of diving masks, including masks used for underwater hiking, also called PMT (Palmes-Mask-Tuba), in English "snorkeling".

Cette activité de randonnée subaquatique permet d'observer les fonds marins tout en nageant à la surface de l'eau. Le randonneur subaquatique doit ainsi pouvoir maintenir la tête sous l'eau tout en respirant.This underwater activity allows you to observe the seabed while swimming on the surface of the water. The underwater hiker must be able to hold the head underwater while breathing.

Généralement, le randonneur subaquatique s'équipe d'un masque pour la vision, et d'un tuba pour la respiration. Le tuba est constitué d'un tube dont l'extrémité inférieure est munie d'une portion buccale qui vient se loger dans la bouche de l'utilisateur, et d'une extrémité supérieure permettant à la fois l'admission d'air frais et l'échappement d'air expiré.Generally, the underwater hiker is equipped with a mask for vision, and a snorkel for breathing. The tuba consists of a tube whose lower end is provided with a mouth portion which is housed in the mouth of the user, and an upper end for both the admission of fresh air and Exhaled air exhaust.

Il est connu qu'un tel matériel présente de nombreux inconvénients. Tout d'abord, le fait de respirer par la bouche n'étant pas naturel, certaines personnes éprouvent des difficultés à respirer oralement à l'aide d'un tuba. Un autre inconvénient est qu'il n'est pas possible de parler sous l'eau lorsque l'on a un tuba dans la bouche.It is known that such a material has many disadvantages. First of all, breathing by mouth is not natural, some people have difficulty breathing orally with a snorkel. Another disadvantage is that it is not possible to speak underwater when you have a snorkel in your mouth.

Encore un autre inconvénient, lié à l'utilisation du masque, est que la paroi intérieure de la visière tend généralement à se couvrir de buée, ce qui nuit à la bonne visibilité, et ce qui contraint l'utilisateur à nettoyer régulièrement son masque. L'apparition de buée est due au fait que le nez de l'utilisateur débouche dans la chambre de vision située entre la visière et les yeux de l'utilisateur.Another disadvantage, related to the use of the mask, is that the inner wall of the visor generally tends to fog, which affects the good visibility, and which forces the user to regularly clean his mask. The appearance of mist is due to the fact that the user's nose opens into the vision chamber located between the visor and the eyes of the user.

Aussi, l'utilisation de ce dispositif masque-tuba est peu confortable.Also, the use of this mask-snorkel device is uncomfortable.

Pour remédier à cet inconvénient, le document FR 2 720 050 propose un masque de plongée permettant de respirer par le nez et par la bouche.To remedy this drawback, the document FR 2,720,050 offers a diving mask to breathe through the nose and mouth.

Pour ce faire, le masque de plongée comporte :

  • un cadre ayant une partie supérieure ;
  • une visière fixée au cadre ;
  • une jupe souple fixée au cadre, la jupe comportant une cloison délimitant une chambre supérieure pour la vision d'une chambre inférieure pour la respiration, la cloison étant agencée pour être en appui au-dessus du nez de l'utilisateur de manière que la bouche et le nez de l'utilisateur se trouvent dans la chambre inférieure, pendant que les yeux de l'utilisateur se trouvent dans la chambre supérieure, la cloison comportant au moins un passage agencé pour permettre une circulation d'air inspiré dirigée de la chambre supérieure vers la chambre inférieure lors d'une phase d'inspiration de l'utilisateur ;
  • un tuba ayant un canal d'admission d'air inspiré et au moins un premier canal d'échappement d'air expiré, ledit tuba étant dans le prolongement de la partie supérieure du cadre, le canal d'admission d'air inspiré débouchant dans la chambre supérieure, tandis que le premier canal d'échappement d'air expiré communique avec la chambre inférieure.
To do this, the diving mask includes:
  • a frame having a top portion;
  • a visor attached to the frame;
  • a flexible skirt attached to the frame, the skirt comprising a partition defining an upper chamber for the vision of a lower chamber for breathing, the partition being arranged to bear above the nose of the user so that the mouth and the nose of the user are in the lower chamber, while the eyes of the user are in the upper chamber, the partition having at least one passage arranged to allow an inspired air flow directed from the upper chamber to the lower chamber during a phase of inspiration of the user;
  • a snorkel having an inspired air intake channel and at least a first exhaled air exhaust channel, said snorkel being in the extension of the upper part of the frame, the inspired air intake channel opening into the upper chamber, while the first exhaled air exhaust channel communicates with the lower chamber.

Selon ce document, l'air expiré circule dans la jupe constituée d'un joint creux souple qui adhère entre le masque et le visage.According to this document, the exhaled air circulates in the skirt constituted by a flexible hollow seal which adheres between the mask and the face.

Un tel masque présente toutefois un inconvénient. Si l'utilisateur sert trop fort le système de fixation du masque, le joint creux souple va venir s'écraser contre le visage, ce qui va provoquer l'obstruction de la conduite par laquelle s'écoule le flux d'air expiré. En revanche, si l'utilisateur ne sert pas suffisamment le système de fixation, il n'y aura pas une parfaite étanchéité entre le visage et la jupe, à la suite de quoi de l'eau risque de pénétrer à l'intérieur des chambres inférieure ou supérieure, ce qui n'est pas désirable.Such a mask, however, has a disadvantage. If the user uses the mask attachment system too hard, the flexible hollow seal will crash against the face, which will cause the obstruction of the line through which the expired airflow flows. On the other hand, if the user does not sufficiently serve the fixing system, there will not be a perfect seal between the face and the skirt, as a result of which water may penetrate inside the chambers. lower or higher, which is not desirable.

Objet et résumé de l'inventionObject and summary of the invention

Un but de l'invention est de proposer un masque de plongée remédiant notamment aux inconvénients précités.An object of the invention is to provide a diving mask remedies including the aforementioned drawbacks.

L'invention atteint son but par le fait que :

  • le cadre est rigide, et
  • dans le cadre est ménagé au moins un premier conduit interne pour l'air expiré, ledit premier conduit interne présentant une extrémité supérieure débouchant dans le canal d'échappement d'air expiré, et une extrémité inférieure communiquant fluidiquement avec la chambre inférieure.
The invention achieves its goal by the fact that:
  • the frame is rigid, and
  • in the frame is provided at least a first internal duct for exhaled air, said first inner duct having an upper end opening into the exhaled air exhaust duct, and a lower end fluidly communicating with the lower chamber.

Dans la mesure où le cadre est rigide, on comprend que le premier conduit interne ne peut pas être écrasé sur lui-même, contrairement au joint creux de l'art antérieur.Insofar as the frame is rigid, it is understood that the first inner conduit can not be crushed on itself, unlike the hollow seal of the prior art.

Le cadre présente donc au moins une double fonction, à savoir maintenir la visière et constituer un moyen de circulation de l'air.The frame therefore has at least a dual function, namely to maintain the visor and constitute a means of air circulation.

La connexion entre le cadre et la jupe souple est préférentiellement obtenue par une jonction souple entre la jupe souple et l'extrémité inférieure du premier conduit interne.The connection between the frame and the flexible skirt is preferably obtained by a flexible junction between the flexible skirt and the lower end of the first inner conduit.

De préférence, le cadre comporte une portion supérieure et une portion inférieure assemblée avec la portion supérieure, et le premier conduit interne est ménagé dans la portion supérieure. Encore de préférence, le premier conduit interne débouche à l'extrémité inférieure de la portion supérieure.Preferably, the frame comprises an upper portion and a lower portion assembled with the upper portion, and the first inner conduit is formed in the upper portion. More preferably, the first inner conduit opens at the lower end of the upper portion.

Avantageusement, la jupe souple comporte en outre au moins un premier manchon faisant saillie depuis un premier bord latéral de la jupe souple en s'étendant vers la partie supérieure du masque, le premier manchon présentant une extrémité inférieure débouchant dans la chambre inférieure et une extrémité supérieure, opposée à l'extrémité inférieure, connectée fluidiquement avec l'extrémité inférieure du premier conduit interne.Advantageously, the flexible skirt further comprises at least a first sleeve projecting from a first lateral edge of the flexible skirt extending towards the upper part of the mask, the first sleeve having a lower end opening into the lower chamber and one end. upper, opposite the lower end, fluidly connected with the lower end of the first inner conduit.

En outre, le manchon faisant saillie depuis le premier bord latéral de la jupe souple, il ne risque pas d'être écrasé sur lui-même en cas de serrage important du système de fixation.In addition, the sleeve projecting from the first side edge of the flexible skirt, it is not likely to be crushed on itself in case of significant tightening of the fastening system.

De préférence, la jupe souple est réalisée en silicone, tandis que le cadre est réalisé en plastique rigide, tel que du polypropylène ou du polycarbonate.Preferably, the flexible skirt is made of silicone, while the frame is made of rigid plastic, such as polypropylene or polycarbonate.

Avantageusement, le cadre comporte au moins un premier raccord latéral engagé dans l'extrémité supérieure du premier manchon.Advantageously, the frame comprises at least a first lateral connection engaged in the upper end of the first sleeve.

De préférence, ce premier raccord latéral s'étend vers la partie inférieure du masque. Ce premier raccord latéral est préférentiellement courbé vers l'intérieur du masque.Preferably, this first lateral connection extends towards the lower part of the mask. This first lateral connection is preferably curved towards the inside of the mask.

Encore de préférence, l'extrémité supérieure du premier manchon présente une section transversale inférieure plus petite que la section transversale du premier raccord latéral. Un intérêt est d'améliorer l'étanchéité entre l'extrémité supérieure du premier manchon et le premier raccord latéral.More preferably, the upper end of the first sleeve has a lower cross section smaller than the cross section of the first side connector. An interest is to improve the seal between the upper end of the first sleeve and the first lateral connection.

Préférentiellement, l'extrémité supérieure du premier manchon affleure un côté latéral du cadre, ce qui permet d'obtenir un cadre ayant un côté latéral dépourvu d'aspérité. Grâce à cet agencement, le manchon n'offre pas de prise, et ne risque donc pas d'être désaccouplé par inadvertance du premier raccord latéral.Preferably, the upper end of the first sleeve is flush with a lateral side of the frame, which makes it possible to obtain a frame having a lateral side devoid of roughness. Thanks to this arrangement, the sleeve does not provide a plug, and therefore does not risk being inadvertently disconnected from the first side connector.

Selon un mode de réalisation préféré, le premier raccord latéral comporte au moins une nervure sur sa face extérieure, ladite nervure coopérant avec la face intérieure de l'extrémité supérieure du premier manchon. L'extrémité supérieure du premier manchon se déforme au contact de la nervure. Cela permet d'améliorer l'étanchéité entre le premier manchon et le premier raccord latéral, tout en améliorant l'ancrage du premier manchon au premier raccord latéral.According to a preferred embodiment, the first lateral connection comprises at least one rib on its outer face, said rib cooperating with the inner face of the upper end of the first sleeve. The upper end of the first sleeve deforms in contact with the rib. This improves the seal between the first sleeve and the first lateral connection, while improving the anchoring of the first sleeve to the first lateral connection.

Avantageusement, le cadre comporte une portion supérieure et une portion inférieure, le premier conduit interne est ménagé dans la portion supérieure du cadre, le premier conduit interne s'étend entre le sommet du cadre et une extrémité inférieure de la portion supérieure du cadre, et le premier raccord latéral fait saillie depuis l'extrémité inférieure de la portion supérieure.Advantageously, the frame comprises an upper portion and a lower portion, the first inner duct is formed in the upper portion of the frame, the first inner duct extends between the top of the frame and a lower end of the upper portion of the frame, and the first lateral connection projects from the lower end of the upper portion.

Selon un mode de réalisation préférentiel, la portion inférieure du cadre présente une extrémité supérieure assemblée avec l'extrémité inférieure de la portion supérieure. Dans ce mode de réalisation, le cadre est constitué d'au moins deux pièces, à savoir la portion supérieure constituant un cerclage supérieur entourant la périphérie supérieure de la jupe souple, et la portion inférieure, formée d'un ou plusieurs éléments, constituant un cerclage inférieur entourant la périphérie inférieure de la jupe souple.According to a preferred embodiment, the lower portion of the frame has an upper end assembled with the lower end of the upper portion. In this embodiment, the frame consists of at least two parts, namely the upper portion constituting an upper hoop surrounding the upper periphery of the flexible skirt, and the lower portion, formed of one or more elements constituting a lower strapping surrounding the lower periphery of the flexible skirt.

Un tel agencement est avantageux dès lors qu'il permet de fabriquer le masque en un minimum de pièces.Such an arrangement is advantageous since it allows the mask to be manufactured in a minimum of parts.

La portion supérieure, constituant un cerclage supérieur, est préférentiellement moulée en une seule pièce.The upper portion, constituting an upper strapping, is preferably molded in one piece.

Selon une variante, la portion inférieure et la portion supérieure forment une seule et même pièce.According to a variant, the lower portion and the upper portion form a single piece.

Selon un mode d'assemblage préférentiel, la jupe souple est fixée aux portions supérieure et inférieure du cadre.According to a preferred method of assembly, the flexible skirt is attached to the upper and lower portions of the frame.

Avantageusement, la jupe comporte une lèvre d'étanchéité périphérique agencée pour venir en appui contre le visage de l'utilisateur, et le premier manchon flanque ladite lèvre d'étanchéité périphérique.Advantageously, the skirt comprises a peripheral sealing lip arranged to bear against the face of the user, and the first sleeve flanks said peripheral sealing lip.

Ainsi, le premier manchon s'étend à l'extérieur de la jupe souple en remontant vers la partie supérieure du masque. Cela permet d'éviter un écrasement du premier manchon sur lui-même, et donc une obstruction du manchon, tout en favorisant un écoulement du flux d'air expiré vers la portion supérieure du cadre, ce qui favorise l'évacuation de l'air vicié.Thus, the first sleeve extends outside the flexible skirt up towards the upper part of the mask. This avoids a crushing the first sleeve on itself, and thus an obstruction of the sleeve, while promoting a flow of exhaled air flow to the upper portion of the frame, which promotes the evacuation of stale air.

Avantageusement, la cloison forme une seule et même pièce avec la jupe souple. La jupe souple est donc une unique pièce, étant entendu que le premier manchon forme une seule et même pièce avec la jupe souple.Advantageously, the partition forms a single piece with the flexible skirt. The flexible skirt is a single piece, it being understood that the first sleeve forms a single piece with the flexible skirt.

Avantageusement, la jupe souple comporte un manchon sommital coopérant avec un raccord sommital du cadre dans lequel débouche le canal d'admission d'air inspiré du tuba, ledit manchon sommital débouchant dans la chambre supérieure.Advantageously, the flexible skirt comprises an upper sleeve cooperating with a top fitting of the frame in which opens the intake air channel inspired tuba, said upper sleeve opening into the upper chamber.

De préférence, le manchon sommital forme une seule et même pièce avec la jupe souple. Encore de préférence, le manchon sommital est disposé entre la lèvre périphérique et la portion supérieure du cadre.Preferably, the top sleeve forms a single piece with the flexible skirt. More preferably, the top sleeve is disposed between the peripheral lip and the upper portion of the frame.

Préférentiellement, le raccord sommital fait saillie depuis une portion supérieure du cadre, tandis que le manchon sommital fait saillie depuis un bord supérieur de la jupe souple, le raccord sommital venant s'engager à l'intérieur du manchon sommital.Preferably, the top fitting protrudes from an upper portion of the frame, while the top sleeve protrudes from an upper edge of the flexible skirt, the top fitting engaging inside the top sleeve.

La section transversale du manchon sommital est légèrement inférieure à la section transversale du raccord sommital afin d'assurer une étanchéité entre les deux éléments. Encore de préférence, le manchon sommital comporte au moins une nervure faisant saillie depuis sa face extérieure, ladite nervure coopérant avec une paroi interne du raccord sommital, et ce afin d'améliorer encore l'étanchéité entre les deux éléments connectés l'un à l'autre.The cross section of the top sleeve is slightly smaller than the cross section of the top fitting to provide a seal between the two elements. More preferably, the top sleeve has at least one rib projecting from its outer face, said rib cooperating with an inner wall of the top connector, and to further improve the seal between the two elements connected to each other. 'other.

Selon un mode de réalisation préférentiel de l'invention, le tuba comporte en outre un deuxième canal de sortir d'air expiré, le cadre comporte en outre un deuxième conduit interne pour l'air expiré, qui présente une extrémité supérieure débouchant dans le deuxième canal d'air expiré, et une extrémité inférieure communiquant fluidiquement avec la chambre inférieure.According to a preferred embodiment of the invention, the tuba further comprises a second exhaled air outlet channel, the frame further comprises a second internal duct for exhaled air, which has an upper end opening into the second exhaled air channel, and a lower end fluidly communicating with the lower chamber.

Ainsi, le masque selon l'invention comporte deux circuits indépendants pour l'air expiré. Un tel agencement présente plusieurs avantages. En premier lieu, il facilite la respiration, notamment en permettant d'expulser plus rapidement l'air vicié, ce qui est notamment nécessaire lorsque l'utilisateur fait un effort musculaire, par exemple en nageant plus rapidement. En deuxième lieu, le randonneur subaquatique peut continuer à respirer quand bien même l'un des deux circuits d'air expiré, par exemple le premier conduit interne, viendrait à se boucher.Thus, the mask according to the invention comprises two independent circuits for exhaled air. Such an arrangement has several advantages. In the first place, it facilitates breathing, in particular by making it possible to expel the stale air more quickly, which is particularly necessary when the user makes a muscular effort, for example in swimming faster. In the second place, the underwater hiker can continue to breathe even if one of the two expired air circuits, for example the first internal duct, would become clogged.

Avantageusement, la jupe souple comporte un deuxième manchon faisant saillie depuis un deuxième bord latéral de la jupe, opposé au premier bord latéral, ledit deuxième manchon présentant une extrémité inférieure débouchant dans la chambre inférieure et une extrémité supérieure, opposée à l'extrémité inférieure, connectée fluidiquement avec l'extrémité inférieure du deuxième conduit interne.Advantageously, the flexible skirt comprises a second sleeve projecting from a second lateral edge of the skirt, opposite to the first lateral edge, said second sleeve having a lower end opening into the lower chamber and an upper end, opposite to the lower end, fluidly connected with the lower end of the second inner conduit.

Avantageusement, le tuba présente une partie supérieure munie d'une cage perméable à l'air, le tuba comportant en outre un flotteur mobile dans ladite cage, ledit flotteur comportant une extrémité supérieure muni d'un dispositif d'obturation, ledit flotteur étant agencé de telle manière que lorsque le tuba est immergé dans l'eau, le flotteur se déplace en sorte que le dispositif d'obturation vient fermer l'entrée du tuba.Advantageously, the tuba has an upper portion provided with a cage permeable to air, the tuba further comprising a float movable in said cage, said float having an upper end provided with a closure device, said float being arranged so that when the tuba is immersed in the water, the float moves so that the closure device closes the inlet of the tuba.

De préférence, le flotteur est un élément creux contenant un volume d'air, tandis que le dispositif d'obturation est constitué d'une membrane souple. Encore de préférence, le flotteur comporte un corps dans lequel est emmanchée la membrane souple, ce qui confère au flotteur une très bonne robustesse.Preferably, the float is a hollow element containing a volume of air, while the closure device consists of a flexible membrane. Still preferably, the float comprises a body in which is fitted the flexible membrane, which gives the float very good strength.

La cage perméable à l'air est de préférence constituée par une portion supérieure du tuba dans laquelle sont ménagées des fentes.The air permeable cage is preferably constituted by an upper portion of the tuba in which slots are formed.

De préférence, la cage comporte en sa partie inférieure des trous pour l'évacuation de l'eau qui pourrait entrer dans cette dernière.Preferably, the cage has in its lower part holes for the evacuation of water that could enter the latter.

La cage est par ailleurs disposée sur un flanc de la partie supérieure du corps du tuba dans lequel s'étendent les canaux d'admission et d'échappement.The cage is also disposed on a side of the upper body of the tuba in which the inlet and exhaust channels extend.

Avantageusement, le tuba comporte en outre une plaquette comportant :

  • un orifice principal communiquant avec l'entrée du tuba ;
  • un orifice d'entrée communiquant avec l'entrée du canal d'admission d'air inspiré ;
  • au moins un premier orifice de sortie communiquant avec la sortie du premier canal d'échappement ;
  • un premier clapet anti-retour agencé pour obturer l'orifice d'entrée lors d'une phase d'expiration ;
  • un deuxième clapet anti-retour agencé pour obturer le premier orifice de sortie lors d'une phase d'inspiration ;
  • le tuba comportant en outre une chambre de communication fluidique dans laquelle débouchent l'orifice principal, l'orifice d'entrée et le premier orifice de sortie.
Advantageously, the tuba further comprises a plate comprising:
  • a main port communicating with the entrance of the tuba;
  • an inlet port communicating with the inlet of the inspired air intake channel;
  • at least a first output port communicating with the output of the first exhaust channel;
  • a first non-return valve arranged to close the inlet orifice during an expiration phase;
  • a second non-return valve arranged to close the first outlet orifice during an inspiration phase;
  • the tuba further comprising a fluidic communication chamber into which open the main port, the inlet and the first outlet.

On comprend que le dispositif d'obturation est configuré pour obturer l'orifice principal dans le cas où le tuba est immergé dans l'eau. Pour ce faire, le flotteur immergé, subissant une poussée d'Archimède, se déplace jusqu'à ce que le dispositif d'obturation, de préférence une membrane souple, vienne obturer l'orifice principal. Dans ce cas, l'entrée du tuba est obturée. L'utilisateur ne risque donc pas d'aspirer de l'eau. Il peut toutefois expirer car le flux d'air expiré peut contrecarrer la poussée d'Archimède agissant sur le flotteur.It is understood that the shutter device is configured to close the main orifice in the case where the snorkel is immersed in water. To do this, the submerged float, undergoing an Archimedes pressure, moves until the closure device, preferably a flexible membrane, closes the main orifice. In this case, the entrance of the tuba is closed. The user is therefore unlikely to suck water. It may, however, expire as the expired airflow can counteract the buoyancy force acting on the float.

Lorsque le tuba est hors de l'eau, et lors d'une phase d'inspiration, l'air frais entre dans la chambre de communication fluidique par l'orifice principal dès lors que le flotteur, en position basse en raison de l'utilisation de la pesanteur, n'obstrue pas l'entrée du tuba. Le deuxième clapet anti-retour est obturé tandis que le premier clapet laisse passer l'air frais de la chambre de communication fluidique au travers de l'orifice d'entrée, l'air frais s'écoulant alors successivement dans le canal d'admission d'air inspiré, dans la chambre supérieure via le raccord sommital et le manchon sommital, puis dans la chambre inférieure où il est inspiré par l'utilisateur. On précise que la valve anti-retour de la cloison permet à l'air inspiré de traverser la cloison.When the snorkel is out of the water, and during an inspiration phase, the fresh air enters the fluidic communication chamber through the main orifice when the float, in the down position because of the use of gravity, does not obstruct the entrance of the tuba. The second check valve is closed while the first valve passes fresh air from the fluidic communication chamber through the inlet, the fresh air then flowing successively into the intake channel. of inspired air, in the upper chamber via the top fitting and the top sleeve, then into the lower chamber where it is inspired by the user. It is specified that the non-return valve of the partition allows the inspired air to pass through the partition.

Lorsque le tuba est hors de l'eau, et lors d'une phase d'expiration, l'air expiré par l'utilisateur dans la chambre inférieure s'écoule successivement dans le premier manchon, (ainsi que dans le deuxième manchon lorsqu'il est présent), puis dans le premier conduit interne, (et dans le deuxième conduit interne lorsqu'il est présent), puis dans le premier canal d'échappement d'air expiré, (et dans le deuxième canal d'échappement d'air expiré lorsqu'il est présent). L'air expiré s'écoule alors dans la chambre de communication fluidique via le premier orifice de sortie puis sort de la chambre de communication fluidique via l'orifice principal. L'air vicié s'échappe alors hors du tuba.When the snorkel is out of the water, and during an expiration phase, the air exhaled by the user in the lower chamber flows successively into the first sleeve, (as well as into the second sleeve when it is present), then in the first internal duct, (and in the second internal duct when it is present), then in the first exhaled air exhaust duct, (and in the second exhaust duct of air expired when present). The exhaled air then flows into the fluidic communication chamber via the first exit port and exits the fluidic communication chamber via the main port. The stale air then escapes out of the tuba.

De préférence, le tuba comporte un corps ayant une extrémité supérieure, le canal d'admission d'air inspiré et le premier canal d'échappement d'air expiré s'étendent dans le corps, et la chambre de communication fluidique est ménagée dans un capot fixé de manière étanche à l'extrémité supérieure du corps.Preferably, the tuba has a body having an upper end, the inspired air intake channel and the first exhaled air exhaust channel extend into the body, and the fluidic communication chamber is formed in a hood tightly attached to the upper end of the body.

Selon un aspect avantageux de l'invention, le tuba est amovible ou inclinable. Cela permet de réduire l'encombrement du masque lorsque ce dernier n'est pas utilisé.According to an advantageous aspect of the invention, the tuba is removable or tilting. This reduces the size of the mask when it is not used.

Avantageusement, le masque selon l'invention comporte en outre une sangle de maintien élastique qui s'étend entre une portion supérieure du cadre et une portion inférieure du cadre.Advantageously, the mask according to the invention further comprises an elastic holding strap which extends between an upper portion of the frame and a lower portion of the frame.

De préférence, la sangle élastique comporte au moins un point de liaison avec l'une ou l'autre des portions inférieure ou supérieure du cadre, ledit point de liaison étant constitué par la coopération d'une extrémité en bourrelet de la sangle élastique avec une fente formée dans la portion inférieure ou supérieure du cadre.Preferably, the elastic strap comprises at least one point of connection with one or the other of the lower or upper portions of the frame, said connection point being constituted by the cooperation of a beaded end of the elastic strap with a slot formed in the lower or upper portion of the frame.

Un intérêt est de faciliter l'opération de montage de la sangle élastique, son maintien par rapport au cadre.An interest is to facilitate the mounting operation of the elastic strap, its retention relative to the frame.

De préférence, la fente est formée par un passant fixé au cadre.Preferably, the slot is formed by a loop fixed to the frame.

Encore de préférence, la sangle élastique comporte deux points de liaison supérieurs avec la portion supérieure du cadre, et deux points de liaison inférieurs avec la portion inférieure du cadre.Still preferably, the elastic strap has two upper connection points with the upper portion of the frame, and two lower connection points with the lower portion of the frame.

Ainsi, la sangle élastique présente la forme d'un « X » qui permet de couvrir la partie arrière de la tête de l'utilisateur, ce qui a pour effet d'offrir un maintien stable du masque sur la tête de l'utilisateur.Thus, the elastic strap has the shape of an "X" that covers the rear portion of the user's head, which has the effect of providing a stable maintenance of the mask on the user's head.

En outre, la portion supérieure du cadre présente avantageusement une triple fonction, à savoir maintenir la visière, former un moyen d'écoulement de l'air expiré et inspiré, et permettre la fixation de la sangle élastique.In addition, the upper portion of the frame advantageously has a triple function, namely to maintain the visor, form an exhaled and inspired air flow means, and allow the attachment of the elastic strap.

Avantageusement, le masque de plongée selon l'invention comporte en outre une valve de purge disposée dans la chambre de respiration pour l'évacuation de liquide hors du masque. Par une forte expiration, l'eau éventuellement contenue dans la chambre inférieure sera expulsée hors du masque via la valve de purge.Advantageously, the diving mask according to the invention further comprises a purge valve disposed in the breathing chamber for discharging liquid out of the mask. By a strong expiration, the water possibly contained in the lower chamber will be expelled out of the mask via the purge valve.

De manière préférentielle, pour rendre le port du masque plus confortable, la cloison comporte un pli formant une lèvre destinée à venir au contact du nez de l'utilisateur.Preferably, to make the wearing of the mask more comfortable, the partition has a fold forming a lip intended to come into contact with the user's nose.

Avantageusement, le passage de la cloison comporte une valve anti-retour agencée pour autoriser une circulation d'air inspiré dirigée uniquement de la chambre supérieure vers la chambre inférieure lors d'une phase d'inspiration de l'utilisateur.Advantageously, the passage of the partition comprises a non-return valve arranged to allow an inspired air flow directed solely from the upper chamber to the lower chamber during a phase of inspiration of the user.

Grâce à la présence de la valve anti-retour, le flux d'air expiré ne remonte pas dans la chambre supérieure, ce qui permet d'améliorer l'efficacité du système antibuée du masque.Thanks to the presence of the non-return valve, the exhaled air flow does not rise in the upper chamber, which improves the efficiency of the anti-mist system of the mask.

Description détaillée de l'inventionDetailed description of the invention

Sur la figure 1 , on a représenté un exemple de réalisation d'un masque de plongée 10 conforme à la présente invention. Le masque de plongée 10 comporte un cadre 12 de forme générale oblongue ayant une partie supérieure 12a et une partie inférieure 12b.On the figure 1 an exemplary embodiment of a diving mask 10 according to the present invention is shown. The diving mask 10 comprises a frame 12 of generally oblong shape having an upper portion 12a and a lower portion 12b .

Dans cet exemple, le cadre 12 comporte une portion supérieure 14 formant un cerclage supérieur et une portion inférieure 16 constituant un cerclage inférieur.In this example, the frame 12 comprises an upper portion 14 forming an upper strapping and a lower portion 16 constituting a lower strapping.

Les portions supérieure 14 et inférieure 16 du cadre sont fixées l'une à l'autre afin de former un cerclage entourant le visage de l'utilisateur.The upper 14 and lower 16 portions of the frame are attached to each other to form a strapping surrounding the face of the user.

Le masque de plongée 10 comporte par ailleurs une visière 18 qui est fixée au cadre 12. Dans cet exemple, la visière 18 est réalisée dans un matériau plastique dur transparent.The diving mask 10 further comprises a visor 18 which is fixed to the frame 12 . In this example, the visor 18 is made of a transparent hard plastic material.

Comme on le comprend à l'aide de la figure 1 , le cadre 12 entoure la visière 18. Ce masque comporte en outre une valve de purge 17 pour l'évacuation de l'eau qui aurait pu entrer dans le masque.As can be understood by using the figure 1 , the frame 12 surrounds the visor 18 . This mask further comprises a purge valve 17 for the evacuation of water that could have entered the mask.

Le masque de plongée 10 comporte par ailleurs un tuba 20 qui comporte une partie inférieure 20a connectée à la partie supérieure 12a du cadre. Dans cet exemple, le tuba 20 est amovible. Il peut être déclipsé du cadre 12, ce qui permet de réduire l'encombrement du masque lorsque ce dernier n'est pas utilisé. Le tuba 20, mieux visible sur la figure 2 , présente par ailleurs une partie supérieure 20b qui est munie d'une cage 22 perméable à l'air.The dive mask 10 further includes a snorkel 20 which has a lower portion 20a connected to the upper portion 12a of the frame. In this example, the tuba 20 is removable. It can be unclipped from the frame 12 , which reduces the size of the mask when the latter is not used. The tuba 20, better visible on the figure 2 , also has an upper portion 20b which is provided with a cage 22 permeable to air.

Comme il sera décrit plus en détail ci-dessous, le tuba 20 comporte en outre un capot 24 qui coopère avec la cage 22.As will be described in more detail below, the tuba 20 further comprises a cover 24 which cooperates with the cage 22 .

En se référant maintenant à la vue éclatée, on constate que la portion inférieure 16 du cadre 12 comporte un premier élément 16' et un deuxième élément 16" qui sont fixés l'un à l'autre afin de former la portion inférieure.Referring now to the exploded view, it can be seen that the lower portion 16 of the frame 12 comprises a first element 16 ' and a second element 16 " which are attached to each other to form the lower portion.

On constate par ailleurs que le tuba 20 comporte un corps 26 longiligne dont l'extrémité inférieure 26a vient s'emmancher avec une extension 28 de la portion supérieure 14 du cadre 12 qui fait saillie depuis l'extrémité supérieure 12a du cadre.It is also noted that the tuba 20 has a body 26 elongate whose lower end 26a is engulfed with an extension 28 of the upper portion 14 of the frame 12 which protrudes from the upper end 12a of the frame.

Par ailleurs, le tuba 20 comporte un flotteur 30 qui est mobile dans la cage 22, le flotteur comportant une extrémité supérieure 30a munie d'un dispositif d'obturation 32. Comme il sera expliqué plus en détail ci-après, le flotteur 30 est agencé de telle manière que lorsque le tuba 20 est immergé dans l'eau, le flotteur se déplace en sorte que le dispositif d'obturation 32, en l'espèce une membrane souple, vient fermer l'entrée du tuba.Furthermore, the tuba 20 comprises a float 30 which is movable in the cage 22 , the float comprising an upper end 30a provided with a closure device 32 . As will be explained in more detail below, the float 30 is arranged in such a way that when the tuba 20 is immersed in the water, the float moves so that the closure device 32 , in this case a flexible membrane, just close the entrance of the tuba.

En se référant aux figures 3, 4 et 5 , on constate que la jupe souple 40 présente une forme générale oblongue sensiblement de même dimension que le cadre 12 et la visière 18. La jupe souple 40 est disposée entre la visière 18 et le cadre 14.Referring to Figures 3, 4 and 5 it can be seen that the flexible skirt 40 has a generally oblong shape substantially of the same size as the frame 12 and the visor 18 . The flexible skirt 40 is disposed between the visor 18 and the frame 14 .

Plus précisément, la jupe souple comporte un pourtour 42 qui présente une partie supérieure qui est fixée avec la portion inférieure du cadre.More specifically, the flexible skirt has a periphery 42 which has an upper portion which is fixed with the lower portion of the frame.

La jupe souple 40 comporte en outre une lèvre d'étanchéité périphérique 44 qui est agencée pour venir en appui contre le visage de l'utilisateur, de manière à éviter que de l'eau pénètre entre le visage de l'utilisateur et la visière.The flexible skirt 40 further comprises a peripheral sealing lip 44 which is arranged to bear against the face of the user, so as to prevent water from entering between the face of the user and the visor.

La jupe souple 40 comporte par ailleurs une cloison 46 qui est agencée pour être en appui au-dessus du nez de l'utilisateur. Cette cloison 46 délimite ainsi une chambre supérieure 50 pour la vision, d'une chambre inférieure 52 pour la respiration. Comme on le conçoit à l'aide de la figure 5 , qui illustre le cadre 12 assemblé avec la visière 18 et la jupe 40, la bouche et le nez de l'utilisateur se trouvent dans la chambre inférieure 52, pendant que les yeux de l'utilisateur se trouvent dans la chambre supérieure 50.The flexible skirt 40 further comprises a partition 46 which is arranged to bear above the nose of the user. This partition 46 thus delimits an upper chamber 50 for viewing, a lower chamber 52 for breathing. As conceived with the help of the figure 5 , which illustrates the frame 12 assembled with the visor 18 and the skirt 40 , the mouth and the nose of the user are in the lower chamber 52 , while the eyes of the user are in the upper chamber 50 .

Autrement dit, la chambre 50 supérieure est délimitée par la visière, les yeux de l'utilisateur, la paroi supérieure 46a de la cloison 46, et la partie de la jupe souple qui s'étend au-dessus de la cloison 46.In other words, the upper chamber 50 is delimited by the visor, the eyes of the user, the upper wall 46a of the partition 46 , and the portion of the flexible skirt which extends above the partition 46 .

Par ailleurs, la chambre inférieure 52 est délimitée par la visière 18, la bouche et le nez de l'utilisateur, la partie inférieure 46b de la cloison 46, et par la partie de la jupe souple qui s'étend en dessous de la cloison 46.Furthermore, the lower chamber 52 is delimited by the visor 18 , the mouth and the nose of the user, the lower portion 46b of the partition 46 , and the portion of the flexible skirt that extends below the partition 46 .

Dans cet exemple, la cloison comporte une paire de passages munis de valves anti-retour 54 qui sont agencées pour autoriser une circulation d'air inspiré dirigée uniquement de la chambre supérieure 50 vers la chambre inférieure 52 lors d'une phase d'inspiration de l'utilisateur. Dans cet exemple, la jupe souple est réalisée en silicone, et forme une seule et même pièce avec la cloison 46, la lèvre d'étanchéité 44 et le pourtour 42.In this example, the partition comprises a pair of passages provided with non-return valves 54 which are arranged to allow an inspired air flow directed solely from the upper chamber 50 to the lower chamber 52 during an inspiration phase of the user. In this example, the flexible skirt is made of silicone, and forms a single piece with the partition 46 , the sealing lip 44 and the periphery 42 .

Sur la figure 6 , on a illustré le tuba 20, vu depuis sa portion inférieure 20a.On the figure 6 the tuba 20 has been illustrated from its lower portion 20a .

On constate que le tuba 20 comprend un canal d'admission d'air inspiré 60 qui s'étend entre l'extrémité inférieure du tuba 20a et l'extrémité supérieure 20b du tuba. Ce canal d'admission d'air inspiré s'étend ainsi selon la direction longitudinale du corps 26. Comme on l'expliquera plus en détail ci-dessous, le canal d'admission d'air inspiré débouche dans la chambre supérieure.It is found that the tuba 20 comprises an inspired air intake channel 60 which extends between the lower end of the tuba 20a and the upper end 20b of the tuba. This inspired air intake channel thus extends in the longitudinal direction of the body 26 . As will be explained in more detail below, the inspired air intake channel opens into the upper chamber.

Le tuba 20 comporte par ailleurs un premier canal d'échappement d'air expiré 62, qui s'étend également selon la direction longitudinale du corps 26 entre la partie inférieure 20a et la partie supérieure 20b du tuba 20. Ce premier canal d'échappement d'air expiré 62 communique avec la chambre inférieure 52.The tuba 20 further comprises a first expired air outlet channel 62 , which also extends in the longitudinal direction of the body 26 between the lower part 20a and the upper part 20b of the tuba 20 . This first expired air exhaust channel 62 communicates with the lower chamber 52 .

Dans cet exemple, le tuba 20 comporte un deuxième canal d'échappement d'air expiré 64 similaire au premier canal d'admission d'air expiré.In this example, the tuba 20 has a second expired air exhaust channel 64 similar to the first expired air intake channel.

Comme on le constate sur la figure 6 , le canal d'admission d'air inspiré 60 est séparé des premier et deuxième canaux d'échappement d'air 62, 64 par deux parois longitudinales 66, 68.As we see on the figure 6 , the inspired air intake channel 60 is separated from the first and second air exhaust ducts 62 , 64 by two longitudinal walls 66 , 68 .

Comme on le constate sur la figure 7 , qui représente le cadre 12 assemblé à la jupe souple 40 en vue de dessus, l'extension 28 comporte également un canal central 70 agencé pour communiquer avec le canal d'admission d'air inspiré 60 lorsque le tuba est fixé au cadre, et deux canaux d'expiration 72, 74 agencés pour communiquer respectivement avec les premier et deuxième canaux d'échappement d'air expiré 62,64.As we see on the figure 7 , which represents the frame 12 assembled to the flexible skirt 40 in plan view, the extension 28 also comprises a central channel 70 arranged to communicate with the inspired air intake channel 60 when the tuba is fixed to the frame, and two exhalation channels 72 , 74 arranged to communicate respectively with the first and second expired air exhaust ducts 62 , 64 .

En se référant maintenant à la figure 8 , on constate que le cadre 12 comporte en outre un raccord sommital 80 qui fait saillie depuis la portion supérieure 14 du cadre 12. La jupe souple 40 comporte quant à elle un manchon sommital 82 qui fait saillie depuis une partie supérieure de la jupe souple 40 en débouchant dans la chambre supérieure 50. On constate que le raccord sommital 80 vient s'engager à l'intérieur du manchon sommital 82 afin de créer une liaison étanche entre ces deux éléments. Sur la figure 8 , la flèche F1 symbolise le flux d'air frais inspiré.Referring now to the figure 8 it can be seen that the frame 12 further comprises a top connection 80 which projects from the upper portion 14 of the frame 12 . The flexible skirt 40 comprises a top sleeve 82 which protrudes from an upper portion of the flexible skirt 40 , opening into the upper chamber 50 . It is noted that the top fitting 80 engages inside the top sleeve 82 to create a tight connection between these two elements. On the figure 8 , arrow F1 symbolizes the flow of fresh air inspired.

On comprend que lors d'une phase d'inspiration, l'air frais rentre dans le tuba, s'écoule dans le canal d'admission d'air inspiré, puis dans la chambre supérieure 50 en traversant le manchon sommital 82.It is understood that during an inspiration phase, fresh air enters the tuba, flows into the inspired air intake channel, then into the upper chamber 50 through the top sleeve 82 .

On va maintenant s'intéresser au circuit d'air expiré.We will now be interested in the expired air circuit.

Conformément à l'invention, dans le cadre 12, et plus particulièrement dans la partie supérieure 14 dudit cadre, est ménagé un premier conduit interne 90 pour l'air expiré, et un deuxième conduit interne 92 pour l'air expiré. Comme on le constate sur la figure 9 , ces premier et deuxième conduits internes sont disposés de part et d'autre d'un plan longitudinal P du masque. Ce plan P constitue ici le plan de symétrie du masque.According to the invention, in the frame 12 , and more particularly in the upper part 14 of said frame, is provided a first internal conduit 90 for exhaled air, and a second inner conduit 92 for exhaled air. As we see on the figure 9 these first and second internal ducts are arranged on either side of a longitudinal plane P of the mask. This plane P is here the plane of symmetry of the mask.

Dans la mesure où les premier et deuxième conduits internes 90, 92 sont identiques, on va décrire uniquement le premier conduit interne 90. Ce dernier présente une extrémité supérieure 90a qui correspond à la sortie du canal 72 illustré en figure 7 . Le premier conduit interne 90 présente en outre une extrémité inférieure 90b.Insofar as the first and second internal ducts 90 , 92 are identical, only the first internal duct 90 will be described. The latter has an upper end 90a which corresponds to the output of the channel 72 illustrated in FIG. figure 7 . The first inner conduit 90 further has a lower end 90b .

Par ailleurs, conformément à l'invention, la jupe souple 40 comporte en outre un premier manchon 100 faisant saillie depuis un premier bord latéral 41 de la jupe souple 40 en s'étendant vers la partie supérieure 12a du cadre 12. Le premier manchon, qui forme une seule et même pièce avec la jupe souple, présente une extrémité inférieure 100a débouchant dans la chambre inférieure 52 et une extrémité supérieure 100b opposée à l'extrémité inférieure, qui est connectée fluidiquement avec l'extrémité inférieure du premier conduit interne. On comprend que le manchon forme une conduite pour l'air expiré.Furthermore, according to the invention, the flexible skirt 40 further comprises a first sleeve 100 projecting from a first lateral edge 41 of the flexible skirt 40 extending towards the upper part 12a of the frame 12 . The first sleeve, which forms a single piece with the flexible skirt, has a lower end 100a opening into the lower chamber 52 and an upper end 100b opposite the lower end, which is fluidly connected with the lower end of the first one. internal conduit. It is understood that the sleeve forms a pipe for exhaled air.

La jupe souple comporte en outre un deuxième manchon 200, identique au premier manchon 100, le deuxième manchon 200 faisant saillie depuis un deuxième bord latéral 43 de la jupe 40, opposé au premier bord latéral. Le deuxième manchon présente une extrémité inférieure 200a débouchant dans la chambre inférieure 52 et une extrémité supérieure 200b opposée à l'extrémité inférieure qui est connectée fluidiquement avec l'extrémité inférieure 92b du deuxième conduit interne 92.The flexible skirt further comprises a second sleeve 200 , identical to the first sleeve 100 , the second sleeve 200 projecting from a second lateral edge 43 of the skirt 40 , opposite the first side edge. The second sleeve has a lower end 200a opening into the lower chamber 52 and an upper end 200b opposite the lower end which is fluidly connected with the lower end 92b of the second inner conduit 92 .

En se référant à la figure 9 , on constate que le premier conduit interne 90 s'étend entre le sommet du cadre et une extrémité inférieure 14a de la portion supérieure 14 du cadre.Referring to the figure 9 , it is found that the first inner conduit 90 extends between the top of the frame and a lower end 14a of the upper portion 14 of the frame.

En se référant aux figures 9 , 10A et 10B , on constate que le cadre 12, et plus précisément l'extrémité inférieure de la portion supérieure 14 du cadre 12, comporte un premier raccord latéral 110 qui est engagé dans l'extrémité supérieure 100b du premier manchon. Pour améliorer la tenue et l'étanchéité, le premier raccord latéral 110 comporte des nervures 112 sur sa face extérieure 110a, les nervures 112 coopèrent avec la face intérieure 101 de l'extrémité supérieure du premier manchon. En se référant à nouveau à la figure 9 , on constate que l'extrémité supérieure du premier manchon affleure un côté latéral 12c du cadre 12.Referring to figures 9 , 10A and 10B it is found that the frame 12 , and more precisely the lower end of the upper portion 14 of the frame 12 , comprises a first lateral connection 110 which is engaged in the upper end 100b of the first sleeve. To improve the strength and tightness, the first lateral connection 110 has ribs 112 on its outer face 110a , the ribs 112 cooperate with the inner face 101 of the upper end of the first sleeve. Referring again to the figure 9 it is found that the upper end of the first sleeve is flush with a lateral side 12c of the frame 12 .

On comprend donc que l'air expiré s'écoule successivement à travers le premier manchon 100, à travers le premier conduit interne 90 puis à travers le premier canal d'échappement d'air expiré 62. Ce flux d'air sortant est illustré par la flèche F2. La flèche F3 illustre quant à elle l'autre circuit d'air sortant qui s'écoule via le deuxième manchon 200 et le deuxième conduit interne 92.It is therefore understood that the exhaled air flows successively through the first sleeve 100 , through the first inner conduit 90 and then through the first expired air exhaust channel 62 . This outgoing air flow is illustrated by the arrow F2 . The arrow F3 illustrates the other outgoing air circuit that flows via the second sleeve 200 and the second inner conduit 92 .

A l'aide des figures 11 à 13 , on va maintenant décrire plus particulièrement la portion supérieure du tuba 20.With the help of Figures 11 to 13 , the upper portion of the tuba 20 will now be described more particularly.

Le tuba 20 du masque selon l'invention comporte en son extrémité supérieure des moyens pour réguler les entrées et sorties d'air dans le tuba. A cet effet, le tuba 20 comporte une plaquette 300 qui est disposée de manière étanche entre le capot 24 et l'extrémité supérieure 26b du corps 26 du tuba 20.The snorkel 20 of the mask according to the invention comprises at its upper end means for regulating the inflow and outflow of air into the tuba. For this purpose, the tuba 20 comprises a plate 300 which is arranged in a sealed manner between the cap 24 and the upper end 26b of the body 26 of the tuba 20 .

Cette plaquette comporte un orifice principal 302 communiquant avec l'entrée E du tuba. Dans cet exemple, l'entrée E du tuba est réalisée grâce à des fentes 23 ménagées dans la cage 22.This plate has a main port 302 communicating with the inlet E of the tuba. In this example, the inlet E of the snorkel is made by means of slots 23 formed in the cage 22 .

La plaquette 300 comporte en outre un orifice d'entrée 304 communiquant avec l'entrée 60a du canal d'émission d'air inspiré 60.The wafer 300 further includes an inlet port 304 communicating with the inlet 60a of the inspired air emission channel 60 .

La plaquette 300 comporte en outre un premier orifice de sortie 306 qui communique avec la sortie 62a du premier canal d'échappement 62.The wafer 300 further includes a first outlet port 306 which communicates with the outlet 62a of the first exhaust channel 62 .

La plaquette 300 comporte en outre un deuxième orifice de sortie 308 qui communique avec la sortie 64a du deuxième canal d'échappement d'air expiré.The wafer 300 further includes a second outlet port 308 which communicates with the outlet 64a of the second exhaled air outlet channel.

Comme on le constate à l'aide de la figure 11 , les sections de l'orifice principal 302, de l'orifice d'entrée 304 et des deux orifices de sortie 306, 308, correspondent sensiblement aux sections transversales du canal d'admission d'air inspiré 60 et des canaux d'échappement d'air expiré 62, 64. As can be seen from the figure 11 the sections of the main port 302 , the inlet port 304, and the two outlet ports 306 , 308 substantially correspond to the cross-sections of the inspired air intake channel 60 and the exhaust ducts. expired air 62, 64.

La plaquette 300 comporte en outre un premier clapet anti-retour 310 disposé en regard du premier orifice d'entrée 304, afin d'obturer ledit orifice d'entrée lors d'une phase d'expiration. La plaquette 300 comporte en outre un deuxième clapet anti-retour 312, disposé en regard du premier orifice de sortie afin d'obturer ledit premier orifice de sortie lors d'une phase d'inspiration. Et, dans cet exemple, la plaquette 300 comporte également un troisième clapet anti-retour 312 qui est agencé pour obturer le deuxième orifice de sortie lors d'une phase d'inspiration.The wafer 300 further comprises a first non-return valve 310 arranged opposite the first inlet port 304 , in order to close off said inlet orifice during an expiration phase. The wafer 300 further comprises a second non-return valve 312 , arranged opposite the first outlet orifice in order to close said first outlet orifice during an inspiration phase. And, in this example, the plate 300 also comprises a third check valve 312 which is arranged to close the second outlet orifice during an inspiration phase.

Le tuba 20 comporte en outre une chambre de communication fluidique 350 dans laquelle débouchent l'orifice principal 302, l'orifice d'entrée 304, le premier orifice de sortie 306 et le deuxième orifice de sortie 308. La chambre de communication fluidique 350 est ménagée dans le capot 24 qui est fixé de manière étanche à l'extrémité supérieure du corps 26.The tuba 20 further includes a fluid communication chamber 350 into which the main port 302 , the inlet port 304 , the first outlet port 306 and the second outlet port 308 open . The fluidic communication chamber 350 is formed in the cover 24 which is sealingly attached to the upper end of the body 26 .

Sur la figure 12 , on a illustré la configuration du tuba lors d'une phase d'inspiration. On comprend que l'air frais inspiré illustré par la flèche F1, entre dans la cage 22 via les fentes 23, puis entre dans la chambre de communication fluidique 350 via l'office principal 302 puis entre dans le canal d'admission d'air inspiré 60 en traversant l'orifice d'entrée 304, le premier clapet anti-retour 310 étant alors ouvert pour permettre au flux d'air de passer.On the figure 12 , the configuration of the tuba has been illustrated during an inspiration phase. It is understood that the fresh air inspired illustrated by the arrow F1 , enters the cage 22 via the slots 23 , then enters the fluid communication chamber 350 via the main office 302 and enters the air intake channel inspired 60 through the inlet port 304 , the first non-return valve 310 then being open to allow the flow of air to pass.

Sur la figure 13 , on a illustré le cas dans lequel le tuba est immergé dans l'eau. Le flotteur 30, sous l'action de la poussée d'Archimède, remonte dans la cage 22 jusqu'à ce que le dispositif d'obturation 32 vienne obturer l'orifice principal 302, ce qui a pour effet de fermer l'entrée du tuba.On the figure 13 the case in which the tuba is immersed in water has been illustrated. The float 30 , under the action of the buoyancy, rises in the cage 22 until the device shutter 32 comes to close the main port 302 , which has the effect of closing the entrance of the tuba.

Comme illustré en figure 14 , selon un autre aspect avantageux de l'invention, le masque de plongée 10 comporte en outre une sangle de maintien élastique 400 qui s'étend entre la portion supérieure 14 du cadre et la portion inférieure 16. La sangle élastique 400 comporte deux points de liaison 402, 404 avec la portion supérieure 14 et deux points de liaison 406, 408 avec la portion inférieure 16. On constate alors que la sangle élastique forme un X.As illustrated in figure 14 according to another advantageous aspect of the invention, the diving mask 10 further comprises an elastic holding strap 400 which extends between the upper portion 14 of the frame and the lower portion 16 . The elastic strap 400 has two connection points 402, 404 with the upper portion 14 and two connection points 406, 408 with the lower portion 16 . It can be seen that the elastic strap forms an X.

La portion supérieure 14 du cadre 12 comporte par ailleurs deux passants 410, 412 dans lesquels sont engagées les extrémités des deux portions supérieures des portions de sangle 414, 416. On constate que les extrémités de ces deux portions de sangle 414, 416 forment des bourrelets 418, 420 plus larges que les fentes 422, 424 ménagées dans les passants, ce qui a pour effet d'assurer le maintien de la sangle élastique 400 au cadre.The upper portion 14 of the frame 12 further includes two loops 410, 412 in which are engaged the ends of the two upper portions of the strap portions 414, 416 . It can be seen that the ends of these two strap portions 414, 416 form bead 418, 420 wider than the slots 422, 424 formed in the loops, which has the effect of ensuring the maintenance of the elastic strap 400 to the frame. .
