Description

MASQUE DE PLONGEE AYANT UN CORPS MUNI D'UN DISPOSITIF D'ECHAPPEMENT D'AIR EXPIRE COMPORTANT UNE VALVE ANTIRETOUR Arrière-plan de l'invention  DIVE MASK HAVING A BODY HAVING AN EXPIRED AIR EXHAUST DEVICE HAVING AN ANTIRETURN VALVE Background 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 lorsqu'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 talk underwater when you have a snorkel in your mouth.
Aussi, l'utilisation de ce dispositif masque-tuba est peu confortable. Pour remédier à cet inconvénient, le document FR 3 020 620 propose un masque de plongée permettant de respirer par le nez et par la bouche.  Also, the use of this mask-snorkel device is uncomfortable. To remedy this drawback, document FR 3 020 620 proposes a diving mask for breathing through the nose and mouth.
Ce masque de plongée comporte :  This diving mask includes:
un corps muni d'une visière et d'une jupe souple, ladite jupe souple 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 situent dans la chambre inférieure, pendant que les yeux de l'utilisateur se situent dans la chambre supérieure, la cloison comportant au moins un passage agencé pour permettre un écoulement d'air frais entre la chambre supérieure et la chambre inférieure lors d'une phase d'inspiration de l'utilisateur; un tuba disposé en prolongement d'une partie supérieure du corps, le tuba comprenant au moins un conduit d'air ; a body provided with a visor and a flexible skirt, said flexible skirt having 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 a flow of d fresh air between the upper chamber and the lower chamber during a phase of inspiration of the user; a tuba disposed in extension of an upper part of the body, the tuba comprising at least one air duct;
dans lequel le corps comporte un dispositif d'échappement d'air expiré qui relie fluidiquement la chambre inférieure avec le conduit d'air du tuba.  wherein the body has an exhaled air exhaust device that fluidly connects the lower chamber with the tuba air duct.
Ce masque comporte par ailleurs un tuba muni de plusieurs canaux et d'une plaquette qui comporte des clapets anti-retour afin d'obturer les canaux de sortie d'air lors d'une phase d'inspiration, d'une part, et afin d'obturer le canal d'entrée d'air lors d'une phase d'expiration.  This mask also comprises a snorkel provided with a plurality of channels and a plate which comprises non-return valves to close off the air outlet channels during an inspiration phase, on the one hand, and in order to to close the air inlet channel during an expiration phase.
Si un tel tuba donne toute satisfaction à l'usage, la fabrication d'un tel tuba est relativement complexe et coûteuse.  If such a tuba is satisfactory to use, the manufacture of such a tuba is relatively complex and expensive.
Objet et résumé de l'invention Object and summary of the invention
Un premier but de l'invention est de proposer un masque de conception plus simple remédiant aux inconvénients précités.  A first object of the invention is to provide a simpler design mask overcomes the aforementioned drawbacks.
L'invention atteint son but par le fait que le dispositif d'échappement d'air expiré comporte au moins une première valve antiretour agencée pour autoriser un écoulement d'air expiré dirigé de la chambre inférieure vers le conduit d'air du tuba lors d'une phase d'expiration de l'utilisateur, la première valve anti-retour étant fermée lors d'une phase d'inspiration de l'utilisateur.  The invention achieves its object by the fact that the exhaled air exhaust device comprises at least a first check valve arranged to allow a flow of exhaled air directed from the lower chamber to the tuba air duct at the same time. a phase of expiration of the user, the first non-return valve being closed during a phase of inspiration of the user.
On comprend tout d'abord que le tuba est en connexion fluidique avec la chambre supérieure. Pour ce faire, le corps comporte avantageusement un dispositif d'entrée d'air frais qui communique fluidiquement avec le tuba et avec la chambre supérieure.  It is first understood that the tuba is in fluid connection with the upper chamber. To do this, the body advantageously comprises a fresh air inlet device which fluidly communicates with the tuba and with the upper chamber.
Par ailleurs, la première valve anti-retour est située sur le corps du masque alors que, dans l'art antérieur précité, le clapet anti-retour est situé sur une plaquette du tuba.  Furthermore, the first non-return valve is located on the body of the mask while, in the aforementioned prior art, the non-return valve is located on a plate of the tuba.
Selon l'invention, la première valve anti-retour est agencée pour obturer le dispositif d'échappement d'air expiré pendant une phase d'inspiration.  According to the invention, the first non-return valve is arranged to close off the expired air exhaust device during an inspiration phase.
Par ailleurs, la jupe souple est préférentiellement fixée à la visière. En outre, la visière est au moins partiellement transparente. De préférence, elle présente une portion plane transparente qui se situe en regard de la chambre supérieure. Aussi, lors d'une phase d'inspiration, la fermeture de la première valve anti-retour a pour effet que l'air frais ne s'écoule pas via le dispositif d'échappement d'air. Un intérêt est d'éviter l'inspiration de l'air qui vient d'être expiré et qui se trouve encore dans le dispositif d'échappement d'air expiré ou dans le conduit d'air du tuba. Furthermore, the flexible skirt is preferably attached to the visor. In addition, the visor is at least partially transparent. Preferably, it has a transparent flat portion which is located opposite the upper chamber. Also, during an inspiration phase, the closing of the first non-return valve has the effect that the fresh air does not flow via the air exhaust device. An interest is to avoid the inspiration of the air that has just been exhaled and which is still in the expired air exhaust device or in the air duct of the tuba.
Un tel agencement permet de simplifier la conception et la fabrication du tuba dès lors que la première valve anti-retour est dans le corps du masque.  Such an arrangement simplifies the design and manufacture of the tuba when the first non-return valve is in the body of the mask.
Le fonctionnement est le suivant.  The operation is as follows.
Lors d'une phase d'expiration de l'utilisateur, la première valve antiretour s'ouvre et l'air expiré peut s'écouler dans le conduit d'air du tuba via le dispositif d'échappement d'air expiré.  During a user expiration phase, the first check valve opens and the exhaled air can flow into the tuba air duct via the exhaled air exhaust device.
Lors d'une phase d'inspiration, la première valve anti-retour se ferme et l'air frais entre dans le tuba puis s'écoule successivement dans la chambre supérieure et dans la chambre inférieure où se trouvent la bouche et le nez de l'utilisateur. La première valve anti-retour étant fermée, l'utilisateur n'inspire pas l'air qu'il a expiré au cycle respiratoire précédent.  During an inspiration phase, the first non-return valve closes and the fresh air enters the tuba and then flows successively into the upper chamber and into the lower chamber where the mouth and the nose of the 'user. The first non-return valve being closed, the user does not inspire the air that has expired to the previous respiratory cycle.
Avantageusement, la première valve anti-retour est disposée entre la chambre inférieure et le dispositif d'échappement d'air expiré. Aussi, la première valve anti-retour est disposée à proximité de la bouche et du nez de l'utilisateur, ce qui permet de faciliter son ouverture lors d'une phase d'expiration. On comprend que la première valve anti-retour s'ouvre en raison de l'augmentation de la pression dans la chambre inférieure lors de l'expiration.  Advantageously, the first non-return valve is disposed between the lower chamber and the exhaled air exhaust device. Also, the first non-return valve is disposed near the mouth and nose of the user, which facilitates its opening during an expiration phase. It will be understood that the first non-return valve opens due to the increase of the pressure in the lower chamber upon expiration.
La première valve anti-retour peut également être disposée dans la chambre inférieure.  The first non-return valve can also be arranged in the lower chamber.
Avantageusement, la première valve anti-retour est disposée dans le dispositif d'échappement d'air expiré. De préférence, la première valve anti-retour est située en une partie d'extrémité inférieure du dispositif d'échappement d'air expiré afin d'être située à proximité de la chambre inférieure.  Advantageously, the first non-return valve is disposed in the expired air exhaust device. Preferably, the first non-return valve is located at a lower end portion of the expired air exhaust device to be located near the lower chamber.
Avantageusement, la première valve anti-retour comporte une membrane souple.  Advantageously, the first non-return valve comprises a flexible membrane.
De manière très préférentielle, la membrane souple est constituée d'une portion de la jupe souple. Un intérêt est de limiter le nombre de pièces constituant le masque, ce qui permet d'en réduire le coût de fabrication. In a very preferential manner, the flexible membrane consists of a portion of the flexible skirt. An interest is to limit the number of parts constituting the mask, which reduces the cost of manufacture.
Toutefois, sans sortir du cadre de la présente invention, la membrane souple pourrait également être un élément rapporté, distinct de la jupe.  However, without departing from the scope of the present invention, the flexible membrane could also be an insert, separate from the skirt.
Avantageusement, la première valve anti-retour comporte un siège de valve coopérant avec la membrane souple, le siège de valve étant intégré à la visière.  Advantageously, the first non-return valve comprises a valve seat cooperating with the flexible membrane, the valve seat being integrated with the visor.
Là-encore, un intérêt est de limiter le nombre de pièces constituant le masque, permettant de réduire encore le coût de fabrication du masque.  Here again, an interest is to limit the number of parts constituting the mask, further reducing the cost of manufacturing the mask.
De préférence, le siège de valve forme une seule pièce avec la visière. Avantageusement, le siège de valve constitue une partie de la visière.  Preferably, the valve seat forms a single piece with the visor. Advantageously, the valve seat constitutes a part of the visor.
Selon une exemple de réalisation avantageux, mais non exclusif, le dispositif d'échappement d'air expiré comporte au moins un premier canal d'échappement d'air expiré qui s'étend le long d'un des bords latéraux de la visière, la jupe souple ayant une première partie latérale qui recouvre le premier canal d'échappement d'air expiré. Le premier canal d'échappement d'air peut être constitué de deux nervures adjacentes qui font saillies depuis un bord de la visière.  According to an advantageous, but not exclusive, example of embodiment, the exhaled air exhaust device comprises at least a first expired air exhaust channel which extends along one of the lateral edges of the visor, the flexible skirt having a first side portion which covers the first exhaled air outlet channel. The first air exhaust channel may be two adjacent ribs that protrude from an edge of the visor.
La partie latérale de la jupe comporte un bord latéral dans lequel est engagé le premier canal d'échappement afin d'empêcher l'eau de pénétrer dans le premier canal d'échappement d'air. Pour ce faire le bord latéral de la jupe comporte une paroi supérieure et deux parois latérales ; les parois latérales flanquent les deux nervures du premier canal d'échappement, tandis que la paroi supérieure couvre le premier canal d'échappement afin d'assurer l'étanchéité. Par ailleurs, le bord latéral est situé en périphérie extérieure de la lèvre d'étanchéité de la jupe qui est agencée pour venir en appui sur le visage de l'utilisateur.  The side portion of the skirt has a side edge into which the first exhaust channel is engaged to prevent water from entering the first air exhaust channel. To do this the side edge of the skirt has an upper wall and two side walls; the side walls flank the two ribs of the first exhaust channel, while the top wall covers the first exhaust channel to seal. Furthermore, the lateral edge is located at the outer periphery of the sealing lip of the skirt which is arranged to bear on the face of the user.
De préférence, le premier canal d'échappement d'air expiré forme une seule pièce avec la visière. Encore de préférence, les deux nervures adjacentes forment une seule pièce avec la visière.  Preferably, the first exhaled air outlet channel forms a single piece with the visor. Still preferably, the two adjacent ribs form a single piece with the visor.
Encore de préférence, le siège de valve de la première valve anti- retour est constitué par une portion du premier canal d'échappement d'air expiré. De préférence, le corps du masque comporte en outre un cerclage qui entoure la visière. De préférence, le bord périphérique de la jupe est serré entre le cerclage et le premier canal d'échappement. Ceci a pour effet d'empêcher que le bord périphérique de la jupe ne se désaccouple du premier canal d'échappement. Still preferably, the valve seat of the first non-return valve is constituted by a portion of the first exhaled air exhaust channel. Preferably, the body of the mask further comprises a strapping which surrounds the visor. Preferably, the peripheral edge of the skirt is clamped between the strapping and the first exhaust channel. This has the effect of preventing the peripheral edge of the skirt from being disconnected from the first exhaust channel.
Avantageusement, le premier canal d'échappement d'air expiré comprend une portion d'extrémité inférieure comportant au moins une ouverture débouchant dans la chambre inférieure, et la première valve anti-retour est agencée pour obturer ladite ouverture lors d'une phase d'inspiration de l'utilisateur.  Advantageously, the first exhaled air outlet channel comprises a lower end portion having at least one opening opening into the lower chamber, and the first non-return valve is arranged to close said opening during a phase of user inspiration.
De préférence, la membrane souple est située à l'intérieur du premier canal d'échappement d'air expiré, en regard de ladite ouverture. Par ailleurs, l'ouverture est ménagée entre des portions du premier canal d'échappement d'air expiré qui constituent le siège de la première valve anti-retour.  Preferably, the flexible membrane is located inside the first exhaled air exhaust channel, facing said opening. Furthermore, the opening is formed between portions of the first exhaled air exhaust channel which constitute the seat of the first non-return valve.
De préférence, la portion d'extrémité inférieure comporte deux ouvertures adjacentes obturables par la membrane de la première valve anti-retour. Selon une autre variante, la première valve anti-retour pourrait comporter plusieurs membranes souples.  Preferably, the lower end portion has two adjacent openings closable by the membrane of the first non-return valve. According to another variant, the first non-return valve could comprise several flexible membranes.
Avantageusement, le dispositif d'échappement d'air expiré comporte en outre un deuxième canal d'échappement d'air expiré, et une deuxième valve anti-retour agencée pour autoriser un écoulement d'air expiré dirigé de la chambre inférieure vers le conduit d'air du tuba lors d'une phase d'expiration de l'utilisateur, la deuxième valve anti-retour étant fermée lors d'une phase d'inspiration de l'utilisateur.  Advantageously, the exhaled air exhaust device further comprises a second exhaled air outlet channel, and a second non-return valve arranged to allow a flow of exhaled air directed from the lower chamber to the air duct. air of the tuba during a phase of expiration of the user, the second non-return valve being closed during a phase of inspiration of the user.
Le deuxième canal d'échappement d'air expiré est similaire au premier canal d'échappement d'air expiré. Aussi, les premier et deuxième canaux d'échappement d'air expiré se situent de chaque côté du corps du masque.  The second exhaled air exhaust channel is similar to the first exhaled air exhaust channel. Also, the first and second exhaled air exhaust channels are located on each side of the mask body.
Selon un autre aspect avantageux de l'invention, le tuba comporte un unique conduit d'air qui est en communication fluidique avec la chambre inférieure et la chambre supérieure.  According to another advantageous aspect of the invention, the tuba comprises a single air duct which is in fluid communication with the lower chamber and the upper chamber.
Un intérêt est donc de simplifier la conception et la fabrication du tuba, par rapport au tuba de l'art antérieur précité qui comporte trois canaux. Un autre intérêt est de pouvoir disposer de tout le volume intérieur du tuba aussi bien lors des phases d'inspiration que d'expiration, contrairement à l'art antérieur où le tuba est compartimenté en canaux d'entrée et de sortie d'air. Cela permet d'augmenter sensiblement le débit d'air entrant et sortant par rapport au masque de l'art antérieur, ce qui augmente le confort d'utilisation du masque en facilitant la respiration bucco-nasale. An interest is therefore to simplify the design and manufacture of the tuba, compared to the snorkel of the aforementioned prior art which has three channels. Another advantage is to be able to have all the internal volume of the tuba both during the inspiration phase that expiration, unlike the prior art where the tuba is compartmentalized into air inlet and outlet channels. This makes it possible to substantially increase the inflow and outflow of air relative to the mask of the prior art, which increases the comfort of use of the mask by facilitating oral-nasal breathing.
L'unique conduit d'air est donc en communication fluidique avec le dispositif d'échappement d'air expiré, et aussi avec le dispositif d'entrée d'air frais. Encore de préférence, l'unique conduit d'air est en communication fluidique avec les premier et deuxième canaux d'échappement d'air expiré.  The single air duct is therefore in fluid communication with the exhaled air exhaust device, and also with the fresh air inlet device. More preferably, the single air duct is in fluid communication with the first and second expired air exhaust channels.
Avantageusement, la cloison comporte au moins un clapet antiretour agencé pour autoriser uniquement un écoulement d'air frais dirigé de la chambre supérieure vers la chambre inférieure lors d'une phase d'inspiration de l'utilisateur.  Advantageously, the partition comprises at least one non-return valve arranged to allow only a fresh air flow directed from the upper chamber to the lower chamber during a phase of inspiration of the user.
On comprend que le clapet anti-retour s'ouvre lors d'une phase d'inspiration et se ferme lors d'une phase d'expiration. Le clapet antiretour a pour fonction d'empêcher que l'air expiré ne s'écoule vers la chambre supérieure, grâce à quoi on évite l'apparition de buée sur la partie plane de la visière qui est située en regard des yeux de l'utilisateur.  It is understood that the check valve opens during an inspiration phase and closes during an expiration phase. The function of the non-return valve is to prevent the exhaled air from flowing to the upper chamber, thereby preventing fogging on the flat part of the visor which is situated opposite the eyes of the user.
Selon un aspect avantageux de l'invention, le clapet anti-retour comporte un volet souple constitué d'une partie de la jupe souple. De préférence, le volet souple du clapet anti-retour est constitué par une portion de la cloison. Le volet souple est préférentiel lement délimité entre un bord libre de la cloison et une découpe réalisée dans la cloison. Grâce à cette découpe, le volet souple présente une mobilité lui permettant de se plier lors d'une phase d'inspiration de manière à ouvrir ledit passage.  According to an advantageous aspect of the invention, the non-return valve comprises a flexible flap consisting of a portion of the flexible skirt. Preferably, the flexible flap of the non-return valve is constituted by a portion of the partition. The flexible flap is preferably delimited between a free edge of the partition and a cut made in the partition. With this cut, the flexible flap has a mobility allowing it to bend during an inspiration phase so as to open said passage.
Encore de préférence, lors d'une phase d'expiration, le volet souple du clapet anti-retour vient en appui contre la visière afin de fermer ledit passage. Lors d'une phase d'inspiration, le volet souple du clapet anti- retour s'ouvre pour permettre à l'air frais de rentrer dans la chambre inférieure.  Even more preferably, during an expiration phase, the flexible flap of the non-return valve bears against the visor in order to close said passage. During an inspiration phase, the flexible flap of the non-return valve opens to allow fresh air to enter the lower chamber.
Avantageusement, la jupe souple comporte un manchon sommital qui entoure le connecteur sommital de la visière. Un intérêt est d'assurer l'étanchéité entre la jupe est le connecteur en partie supérieure du corps du masque. Brève description des dessins Advantageously, the flexible skirt comprises a top sleeve which surrounds the summit connector of the visor. An interest is to ensure the seal between the skirt is the connector in the upper part of the body of the mask. Brief description of the drawings

Description détaillée de l'invention Sur les figures 1A et 1B, on a illustré un masque de plongée 10 conforme à la présente invention. Detailed description of the invention In Figures 1A and 1B, there is illustrated a diving mask 10 according to the present invention.
Ce masque de plongée comporte un corps 12 destinée à être positionné sur le visage de l'utilisateur, le corps 12 présentant une partie supérieure 14 et une partie inférieure 16.  This diving mask comprises a body 12 intended to be positioned on the face of the user, the body 12 having an upper portion 14 and a lower portion 16.
Comme on le comprend à l'aide des figures 1A et 1B, la partie supérieure 14 du corps 12 est destiné à être disposé à proximité du front de l'utilisateur, tandis que la partie inférieure 16 du corps est destiné à être disposé à proximité du menton de l'utilisateur.  As can be understood from FIGS. 1A and 1B, the upper part 14 of the body 12 is intended to be placed close to the user's forehead, whereas the lower part 16 of the body is intended to be placed in the vicinity of the user's forehead. the user's chin.
Par ailleurs, le masque de plongée 10 comporte un tuba 18 disposé en prolongement de la partie supérieure 14 du corps 12.  Furthermore, the diving mask 10 comprises a snorkel 18 disposed in extension of the upper part 14 of the body 12.
Dans cet exemple, le tuba 18 est monté au corps 12 de manière amovible.  In this example, the tuba 18 is mounted to the body 12 removably.
En se référant à la vue éclatée de la figure 2, on comprend que le corps 12 est principalement constitué d'une visière 20 et d'une jupe souple 22.  Referring to the exploded view of Figure 2, it is understood that the body 12 is mainly constituted by a visor 20 and a flexible skirt 22.
La visière 20 est réalisée dans un matériau rigide, par exemple en polycarbonate, tandis que la jupe souple 22 est réalisée dans un matériau souple par exemple en silicone LSR.  The visor 20 is made of a rigid material, for example polycarbonate, while the flexible skirt 22 is made of a flexible material such as LSR silicone.
La jupe souple 22 est fixée à la visière.  The flexible skirt 22 is attached to the visor.
Le corps 12 comporte par ailleurs un cerclage 24 qui est conformé pour entourer la visière. Ce cerclage 24 a notamment pour fonction d'assurer, ou à tout le moins d'améliorer, la fixation de la jupe souple à la visière 20.  The body 12 further comprises a strapping 24 which is shaped to surround the visor. This strapping 24 has the particular function to ensure, or at least improve, the attachment of the flexible skirt to the visor 20.
Le corps 12 comporte en outre une mentonnière 26 comportant un capot 28 qui recouvre une portion inférieure 30 de la visière ainsi qu'une portion inférieure 32 du cerclage 24. Comme on le constate en figure 2, la portion inférieure 32 du cerclage 24 est fendue et comporte un élément de serrage permettant de serrer le cerclage 24 contre la jupe et la visière.  The body 12 further comprises a chin guard 26 comprising a cover 28 which covers a lower portion 30 of the visor and a lower portion 32 of the strapping 24. As seen in Figure 2, the lower portion 32 of the strapping 24 is slotted and comprises a clamping member for tightening the strapping 24 against the skirt and the visor.
Comme on le constate sur les figures 1A et 1B, le cerclage 24 comporte par ailleurs des fentes 34 destinées à recevoir une ou plusieurs sangles élastiques (non illustrées ici).  As can be seen in FIGS. 1A and 1B, the strapping 24 also has slots 34 for receiving one or more elastic straps (not shown here).
Comme on constate sur la figure 2, le cerclage 24 présente, sur sa face interne 25, des nervures 27 qui ont pour fonction de bloquer la jupe par rapport au cerclage. En se référant aux figures 1A et 3, on constate que la visière 20 est conformée pour recouvrir le visage de l'utilisateur. La visière comporte une portion plane 20a transparente destinée à se situer sensiblement au niveau des yeux de l'utilisateur, et une portion bombée 20b destinée à se trouver au niveau du nez et de la bouche de l'utilisateur. Dans cet exemple non limitatif, la portion bombée 20b est transparente. Toutefois, et sans sortir du cadre de la présente invention, la portion bombée 20b pourrait être opaque ou bien transparente et recouverte d'une capot opaque. As can be seen in FIG. 2, the strapping 24 has, on its internal face 25, ribs 27 whose function is to block the skirt with respect to the strapping. Referring to Figures 1A and 3, it is found that the visor 20 is shaped to cover the face of the user. The visor has a transparent flat portion 20a intended to be located substantially at the level of the eyes of the user, and a curved portion 20b intended to be at the nose and the mouth of the user. In this non-limiting example, the curved portion 20b is transparent. However, and without departing from the scope of the present invention, the curved portion 20b could be opaque or transparent and covered with an opaque cover.
En se référant aux figures 1A, 1B et 2, on constate que la jupe souple 22 comporte une cloison 40 délimitant une chambre supérieure 50 pour la vision d'une chambre inférieure 52 pour la respiration, la cloison 40 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 situent dans la chambre inférieure 52, pendant que les yeux de l'utilisateur se situent dans la chambre supérieure 50.  Referring to FIGS. 1A, 1B and 2, it can be seen that the flexible skirt 22 has a partition 40 delimiting an upper chamber 50 for viewing a lower chamber 52 for breathing, the partition 40 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 52, while the eyes of the user are in the upper chamber 50.
La cloison 40 est fixée à la visière 20 par une pièce de fixation rapportée qui est clippée à des ergots de fixation 53, visibles en figure 3, faisant saille depuis une face interne de la portion bombée 20b.  The partition 40 is fixed to the visor 20 by an attached fastener which is clipped to the fixing lugs 53, visible in Figure 3, projecting from an inner face of the curved portion 20b.
La cloison comporte deux orifices 41 qui s'engagent avec les ergots de fixation 53 avant le positionnement de la pièce de fixation.  The partition has two orifices 41 which engage with the fixing lugs 53 before the positioning of the fastener.
La cloison comporte par ailleurs deux passages 54, mieux visibles sur les figures 2 et 13, qui sont agencés pour permettre un écoulement d'air frais entre la chambre supérieure 50 et la chambre inférieure 52 lors d'une phase d'inspiration de l'utilisateur.  The partition also comprises two passages 54, better visible in FIGS. 2 and 13, which are arranged to allow a flow of fresh air between the upper chamber 50 and the lower chamber 52 during an inspiration phase of the user.
Par ailleurs, dans cet exemple, la cloison comporte deux clapets anti-retour 56 qui sont agencés pour autoriser uniquement un écoulement d'air frais dirigé de la chambre supérieure 50 vers la chambre inférieure 52 lors d'une phase d'inspiration de l'utilisateur.  Furthermore, in this example, the partition comprises two non-return valves 56 which are arranged to allow only a fresh air flow directed from the upper chamber 50 to the lower chamber 52 during an inspiration phase of the user.
On comprend donc que les clapets anti-retour 56 ont pour fonction d'obturer les passages 54 précités lors d'une phase d'expiration de l'utilisateur.  It is therefore understood that the check valves 56 have the function of closing the passages 54 above during an expiration phase of the user.
Dans cet exemple, comme illustré en figure 13, chacun des clapets anti-retour 56 comporte une membrane 58 constituée d'une partie de la jupe souple. Plus précisément, dans cet exemple, chaque membrane 58 est constituée d'une portion de la cloison 40 de la jupe souple. La mobilité des membranes 58 est obtenue par le fait que la cloison comporte deux découpes 60 qui permettent de détacher localement la membrane du reste de la cloison. Grâce à ces découpes, les membranes 58 peuvent se plier et se décoller de la face interne de la visière, notamment lors d'une phase d'inspiration, afin d'ouvrir les passages, ce qui permet de laisser l'air frais entrer dans la chambre inférieure. In this example, as illustrated in FIG. 13, each of the non-return valves 56 comprises a membrane 58 made up of a part of the flexible skirt. More specifically, in this example, each membrane 58 consists of a portion of the partition 40 of the flexible skirt. The mobility of the membranes 58 is obtained by the fact that the partition has two cutouts 60 which make it possible to loosen the membrane locally from the remainder of the partition. Thanks to these cuts, the membranes 58 can fold and peel off the inner face of the visor, especially during an inspiration phase, to open the passages, allowing the fresh air to enter the lower chamber.
Le fonctionnement est le suivant.  The operation is as follows.
Lors d'une phase d'expiration, l'air expiré a pour effet de plaquer les membranes 58 contre la face interne de la portion bombée 20b de la visière, ce qui a pour effet de fermer les passages 54 et donc d'empêcher l'air expiré de passer de la chambre inférieure 52 vers la chambre supérieure 50.  During an expiration phase, the exhaled air has the effect of pressing the membranes 58 against the inner face of the curved portion 20b of the visor, which has the effect of closing the passages 54 and thus preventing the exhaled air to pass from the lower chamber 52 to the upper chamber 50.
Lors d'une phase d'inspiration, la baisse de pression qui intervient dans la chambre inférieure 52 a pour effet de décoller les membranes 58 de la visière 20 et d'ouvrir les passages 54, grâce à quoi l'air frais peut s'écouler du tuba vers la chambre inférieure 52 en passant par la chambre supérieure 50.  During an inspiration phase, the pressure drop that occurs in the lower chamber 52 has the effect of taking off the membranes 58 of the visor 20 and open the passages 54, whereby the fresh air can s' flow from the tuba to the lower chamber 52 through the upper chamber 50.
En se référant à la figure 7, on constate que le tuba 18 comporte une portion tubulaire 70 qui présente une première extrémité 72 et une seconde extrémité 74 opposée la première extrémité 72.  Referring to FIG. 7, it can be seen that the tuba 18 has a tubular portion 70 which has a first end 72 and a second end 74 opposite the first end 72.
Le tuba 18 comporte par ailleurs un capot 76 qui est monté à la seconde extrémité 74 de la portion tubulaire 70.  The tuba 18 further includes a cover 76 which is mounted at the second end 74 of the tubular portion 70.
La portion tubulaire 70 comporte par ailleurs des trous 78 pour permettre les échanges d'air entre l'atmosphère et le masque.  The tubular portion 70 further includes holes 78 to allow the exchange of air between the atmosphere and the mask.
Le tuba 18 comporte par ailleurs un dispositif 80 pour obturer l'entrée d'air du tuba 18 lorsque ce dernier est immergé. Le dispositif 80 comporte un flotteur 82 qui est mobile en translation par rapport à une plaque 84 comportant un premier orifice 86 et un deuxième orifice 88, les premier et deuxième orifices 84 et 86 débouchant dans un volume intérieur du capot 76.  The tuba 18 further comprises a device 80 for closing the air inlet of the tuba 18 when the latter is immersed. The device 80 comprises a float 82 which is movable in translation relative to a plate 84 having a first orifice 86 and a second orifice 88, the first and second orifices 84 and 86 opening into an interior volume of the cap 76.
Le premier orifice 86 communique fluidiquement avec un conduit d'air 90 ménagé dans la portion tubulaire 70 du tuba 18, tandis que le second orifice 88 est disposé en regard du flotteur 82. Le second orifice 88 est bordé par un joint d'étanchéité 92 qui conformée pour coopérer avec le flotteur 82 lorsque le tuba 18 est immergé. The first orifice 86 communicates fluidly with an air duct 90 formed in the tubular portion 70 of the tuba 18, while the second orifice 88 is arranged facing the float 82. The second orifice 88 is bordered by a seal 92 which is shaped to cooperate with the float 82 when the tuba 18 is immersed.
Le fonctionnement est le suivant.  The operation is as follows.
Lorsque le tuba 18 est hors de l'eau, le flotteur 82 est en position basse, de sorte que l'air peut s'écouler entre le conduit d'air 90 et l'atmosphère via les trous 78 en passant successivement par le premier orifice 86, la chambre définie à l'intérieur du capot 76 et le second orifice 88.  When the tuba 18 is out of the water, the float 82 is in the low position, so that the air can flow between the air duct 90 and the atmosphere via the holes 78 by passing successively through the first one. orifice 86, the chamber defined inside the cover 76 and the second orifice 88.
Lors que le tuba 18 est immergé, le flotteur 82 monte pour venir se plaquer contre le joint 92, ce qui a pour effet d'obturer le second orifice 88, en conséquence de quoi l'air ne peut pas entrer dans le conduit d'air 90.  When the tuba 18 is immersed, the float 82 rises to come to press against the seal 92, which has the effect of closing the second orifice 88, as a result of which the air can not enter the duct. air 90.
Par ailleurs, dans cet exemple, la portion tubulaire comporte un unique conduit d'air 90 qui communique avec les chambres inférieure et supérieure.  Furthermore, in this example, the tubular portion comprises a single air duct 90 which communicates with the lower and upper chambers.
Conformément à l'invention, le corps 12 comporte en outre un dispositif d'échappement d'air expiré 100 qui relie fluidiquement la chambre inférieure 52 avec le conduit d'air 90 du tuba 18.  According to the invention, the body 12 further comprises an expired air exhaust device 100 which fluidly connects the lower chamber 52 with the air duct 90 of the tuba 18.
On comprend donc que, lors d'une phase d'expiration, l'air expiré dans la chambre inférieure 52 s'écoule dans le dispositif d'échappement d'air expiré puis dans le conduit d'air 90 du tuba 18 avant de sortir du tuba vers les trous 78.  It is therefore understood that during an expiration phase, the exhaled air in the lower chamber 52 flows into the exhaled air exhaust device and into the air duct 90 of the tuba 18 before exiting from tuba to holes 78.
En référence à la figure 3, le dispositif d'échappement d'air expiré 100 comporte un premier canal d'échappement d'air expiré 102 qui s'étend le long d'un premier bord latéral 104 de la visière.  Referring to Figure 3, the exhaled air exhaust device 100 includes a first expired air exhaust channel 102 which extends along a first side edge 104 of the visor.
Comme on le constate sur la figure 3, le premier canal d'échappement d'air expiré 102 s'étend entre une partie inférieure 20c de la visière 20 et une partie supérieure 20d de la visière.  As can be seen in FIG. 3, the first exhaled air escape channel 102 extends between a lower portion 20c of the visor 20 and an upper portion 20d of the visor.
Le premier canal d'air expiré 102, dans cet exemple, est constitué deux nervures 105, 107 adjacentes qui font saillies depuis un premier bord latéral 20e de la visière.  The first exhaled air channel 102, in this example, consists of two adjacent ribs 105, 107 which project from a first lateral edge 20e of the visor.
Dans cet exemple, le premier canal d'échappement d'air expiré 102 forme une seule pièce avec la visière 20.  In this example, the first exhaled air outlet channel 102 forms a single piece with the visor 20.
Le dispositif d'échappement d'air expiré 100 comporte en outre un deuxième canal d'échappement d'air expiré 104, qui est similaire au premier canal d'échappement d'air expiré 102, et qui s'étend également entre la partie inférieure 20c de la visière et la partie supérieure 20d de la visière. The expired air exhaust device 100 further includes a second exhaled air exhaust channel 104, which is similar to the first exhaled air exhaust channel 102, and which also extends between the lower portion 20c of the visor and the upper portion 20d of the visor.
Le deuxième canal d'échappement d'air expiré étant similaire au premier canal d'échappement d'air expiré, dans la suite de la description on ne décrira que le premier canal d'échappement d'air expiré.  The second exhaled air outlet channel being similar to the first expired air outlet channel, in the remainder of the description only the first exhaled air outlet channel will be described.
La partie supérieure 20d de la visière comporte, en outre, un connecteur sommital 106, qui forme une seule pièce avec le reste de la visière, et qui comporte un conduit central 108, un premier conduit latéral 110, et un deuxième conduit latéral 112.  The upper portion 20d of the visor further comprises an uppermost connector 106, which forms a single piece with the remainder of the visor, and which comprises a central duct 108, a first lateral duct 110, and a second lateral duct 112.
Le conduit central 108 communique fluidiquement avec la chambre supérieure 50, tandis que le premier conduit latéral 110 communique fluidiquement avec le premier canal d'échappement d'air expiré 102, tandis que le second conduit latéral 112 communique fluidiquement avec le deuxième canal d'échappement d'air expiré 104.  The central duct 108 fluidly communicates with the upper chamber 50, while the first lateral duct 110 fluidly communicates with the first exhaled air exhaust duct 102, while the second lateral duct 112 fluidly communicates with the second exhaust duct of exhaled air 104.
Comme on le comprend à l'aide de la figure 3, le premier canal d'échappement d'air expiré 102 et le deuxième canal d'échappement d'air expiré 104 débouchent dans la chambre inférieure 52.  As can be understood from FIG. 3, the first expired air exhaust duct 102 and the second expired air exhaust duct 104 open into the lower chamber 52.
Comme on le comprend à l'aide des figures 8 et 9, la première extrémité 72 de la portion tubulaire 70 du tuba 18 est conformée pour s'accoupler avec le connecteur sommital 106 de la visière.  As can be understood from FIGS. 8 and 9, the first end 72 of the tubular portion 70 of the tuba 18 is shaped to mate with the summit connector 106 of the visor.
En conséquence, on comprend que le conduit central 108, ainsi que les premier et second conduits latéraux 110, 112 débouchent dans l'unique conduit d'air 90 du tuba.  Accordingly, it is understood that the central duct 108, and the first and second lateral ducts 110, 112 open into the single air duct 90 of the tuba.
En se référant à la figure 4, on va maintenant décrire comment la jupe souple 22 est fixée à la visière 20.  Referring to Figure 4, we will now describe how the flexible skirt 22 is attached to the visor 20.
Comme on le comprend à l'aide des figures 1B, 2 et 4, la jupe souple 22 comporte un bord périphérique 120 qui entoure une lèvre d'étanchéité 122.  As can be understood from FIGS. 1B, 2 and 4, the flexible skirt 22 has a peripheral edge 120 which surrounds a sealing lip 122.
Cette lèvre d'étanchéité 122 est conformée pour prendre appui sur le visage de l'utilisateur afin d'éviter que l'eau ne pénètre dans le masque.  This sealing lip 122 is shaped to bear on the face of the user to prevent water from entering the mask.
Le bord périphérique 120 comporte une première partie latérale The peripheral edge 120 has a first lateral portion
124 qui, comme on le comprend à l'aide la figure 4, recouvre le premier canal d'échappement d'air expiré 102. 124 which, as understood in FIG. 4, covers the first expired air exhaust channel 102.
Le bord périphérique de la jupe comporte une première partie latérale dans laquelle est engagé le premier canal d'échappement afin d'empêcher l'eau de pénétrer dans ledit premier canal d'échappement d'air expiré. The peripheral edge of the skirt comprises a first lateral portion in which the first exhaust channel is engaged in order to to prevent water from entering said first exhaled air outlet channel.
Pour ce faire, la première partie latérale du bord périphérique de la jupe 20 comporte une paroi supérieure 126 et deux parois latérales 128, 130. On comprend que la paroi supérieure et les deux parois latérales forment une seule pièce avec la jupe.  To do this, the first lateral portion of the peripheral edge of the skirt 20 has an upper wall 126 and two side walls 128, 130. It is understood that the top wall and the two side walls form a single piece with the skirt.
Les parois latérales 128 et 130 flanquent les deux nervures 105, 107 du premier canal d'échappement d'air expiré tandis que la paroi supérieure couvre le premier canal d'échappement d'air expiré afin d'assurer l'étanchéité.  The sidewalls 128 and 130 flank the two ribs 105, 107 of the first exhaled air exhaust channel while the top wall covers the first expired air exhaust channel to seal.
De préférence, l'une des nervures comporte une portion en saillie longitudinale qui coopère avec l'une ou l'autre des parois latérales du bord périphérique de la jupe afin d'assurer que le bord périphérique reste bien en place par rapport au premier canal d'échappement d'air expiré.  Preferably, one of the ribs has a longitudinal projecting portion which cooperates with one or other of the side walls of the peripheral edge of the skirt to ensure that the peripheral edge remains in place relative to the first channel expired air exhaust.
Le bord périphérique de la jupe souple 22 comporte par ailleurs une deuxième partie latérale 130 qui recouvre le deuxième canal d'échappement d'air expiré 104.  The peripheral edge of the flexible skirt 22 further includes a second lateral portion 130 which covers the second expired air outlet channel 104.
Conformément à l'invention, le dispositif d'échappement d'air expiré 100 comporte une première valve anti-retour 140 qui est agencée pour autoriser un écoulement d'air expiré dirigé de la chambre inférieure 52 vers le conduit d'air 90 du tuba lors d'une phase d'expiration de l'utilisateur.  According to the invention, the exhaled air exhaust device 100 includes a first non-return valve 140 which is arranged to allow a flow of exhaled air directed from the lower chamber 52 to the air duct 90 of the tuba. during an expiry phase of the user.
On comprend donc que, lors d'une phase d'expiration, le volet souple 58 de la cloison 40 se ferme, tandis que la première valve anti- retour 140 du dispositif d'échappement d'air expiré s'ouvre pour laisser l'air expiré s'écouler depuis la chambre inférieure 52 vers le dispositif d'échappement d'air expiré 100, et plus particulièrement vers le premier canal d'échappement d'air expiré 102, puis vers le conduit d'air 90 du tuba pour ensuite être évacué via les trous 78.  It is therefore understood that, during an expiration phase, the flexible flap 58 of the partition 40 closes, while the first non-return valve 140 of the expired air exhaust device opens to let the exhaled air flow from the lower chamber 52 to the expired air exhaust device 100, and more particularly to the first expired air exhaust channel 102, and then to the air duct 90 of the tuba for further be evacuated via the holes 78.
Par ailleurs, la première valve anti-retour 140 est fermée lors d'une phase d'inspiration de l'utilisateur. Aussi, l'utilisateur n'inspire pas l'air vicié (précédemment expiré) contenu dans le tuba ou dans le dispositif d'échappement d'air expiré lors d'une phase d'inspiration.  Furthermore, the first non-return valve 140 is closed during a user inspiration phase. Also, the user does not inspire the stale air (previously exhaled) contained in the tuba or in the expired air exhaust device during an inspiration phase.
Comme on le constate sur les figures 5 et 6, la première valve anti- retour 140 est disposée en une partie d'extrémité inférieure 101 du dispositif d'échappement d'air expiré. Plus exactement, la première valve anti-retour 140 est disposée en une partie d'extrémité inférieure 102a du premier canal d'échappement d'air expiré. As can be seen in FIGS. 5 and 6, the first check valve 140 is disposed at a lower end portion 101 of the exhaled air exhaust device. More exactly, the first valve nonreturn 140 is disposed at a lower end portion 102a of the first expired air exhaust channel.
Dans cet exemple, la première valve anti-retour 140 est disposée entre la chambre inférieure 50 et le dispositif d'échappement d'air expiré 100. Plus précisément, la première valve anti-retour 140 est disposée entre la chambre inférieure 52 et le premier canal d'échappement d'air expiré 102.  In this example, the first non-return valve 140 is disposed between the lower chamber 50 and the expired air exhaust device 100. More specifically, the first non-return valve 140 is disposed between the lower chamber 52 and the first one. exhaled air exhaust duct 102.
Sans sortir du cadre de la présente invention, la première valve anti-retour 140 pourrait être disposée dans la chambre inférieure 52.  Without departing from the scope of the present invention, the first non-return valve 140 could be arranged in the lower chamber 52.
Selon un aspect avantageux de l'invention, la première valve anti¬ retour 140 comporte une membrane souple 142 qui, dans cet exemple, est constituée d'une portion de la jupe souple 22. According to an advantageous aspect of the invention, the first valve anti ¬ return 140 includes a flexible membrane 142 which, in this example, consists of a portion of the flexible skirt 22.
La membrane souple se présente sous la forme d'une portion sensiblement rectangulaire qui fait saillie depuis une face interne de la paroi supérieure 126.  The flexible membrane is in the form of a substantially rectangular portion which projects from an inner face of the upper wall 126.
Sur la figure 6, on a illustré en traits continus la première valve anti-retour en position fermée. Elle est également représentée en traits pointillés en position ouverte.  In Figure 6, there is illustrated in solid lines the first non-return valve in the closed position. It is also represented in dotted lines in the open position.
La première valve anti-retour 140 comporte par ailleurs un siège de valve 144 agencé pour coopérer avec la membrane souple 142, le siège de valve 144 étant intégré à la visière. En position fermée, la membrane souple prend appui sur le siège de valve pour obturer les ouvertures.  The first non-return valve 140 further includes a valve seat 144 arranged to cooperate with the flexible membrane 142, the valve seat 144 being integrated with the visor. In the closed position, the flexible membrane is supported on the valve seat to close the openings.
A l'aide des figures 3, 5 et 6, on constate que le premier canal d'échappement d'air expiré 102 comporte, dans cet exemple, deux ouvertures 150 qui débouchent dans la chambre inférieure 52.  With the aid of FIGS. 3, 5 and 6, it can be seen that the first exhaled air exhaust duct 102 comprises, in this example, two openings 150 which open into the lower chamber 52.
On constate que ces deux ouvertures sont ménagées dans la nervure interne 107 du dispositif d'échappement d'air expiré 100.  It can be seen that these two openings are formed in the internal rib 107 of the expired air exhaust device 100.
La membrane souple 142 est conformée pour obturer les deux ouvertures 150 lors d'une phase d'inspiration de l'utilisateur.  The flexible membrane 142 is shaped to seal the two openings 150 during a phase of inspiration of the user.
On comprend donc que la membrane souple 142 est situé à l'intérieur du premier canal d'échappement d'air expiré 102 en regard des deux ouvertures 150.  It is therefore understood that the flexible membrane 142 is located inside the first expired air outlet channel 102 facing the two openings 150.
Comme expliqué ci-dessus, le dispositif d'échappement d'air expiré 100 comporte en outre le deuxième canal d'échappement d'air expiré 104. Le dispositif d'échappement d'air expiré 100 comporte par ailleurs une deuxième valve anti-retour 160, similaire à la première valve anti¬ retour 140, qui est agencée pour autoriser un écoulement d'air expiré dirigé de la chambre inférieure 52 vers le conduit d'air 90 du tuba lors d'une phase d'expiration de l'utilisateur. As explained above, the expired air exhaust device 100 further includes the second expired air exhaust channel 104. The air exhaust device expired 100 further comprises a second check valve 160, similar to the first check valve ¬ return 140, which is arranged to allow an expired air flow directed from the lower chamber 52 to the air duct 90 of the tuba during an expiration phase of the user.
La deuxième valve anti-retour 160 est fermée lors d'une phase d'inspiration de l'utilisateur.  The second non-return valve 160 is closed during an inspiration phase of the user.
Autrement dit, la deuxième valve anti-retour 160 fonctionne comme la première valve anti-retour 140.  In other words, the second non-return valve 160 functions as the first non-return valve 140.
Toujours en référence aux figures 5 et 6, on constate que la visière comporte, en outre, une valve de purge 180, qui est ménagée dans une partie d'extrémité inférieure de la visière 20.  Still referring to FIGS. 5 and 6, it can be seen that the visor further comprises a bleed valve 180, which is formed in a lower end portion of the visor 20.
Cette valve de purge 180 est partiellement couverte par une plaque de protection 182, qui dans cet exemple, forme une seule pièce avec la visière 20. Cette plaque de protection a pour fonction d'éviter un endommagement de la valve de purge 180.  This purge valve 180 is partially covered by a protection plate 182, which in this example forms a single piece with the visor 20. This protective plate serves to prevent damage to the purge valve 180.
En se référant aux figures 7, 8 et 9, on constate que le masque comporte un système de verrouillage déverrouillable du tuba au corps. Ce système de verrouillage comporte, dans cet exemple, une languette 200 qui s'étend depuis la première extrémité 72 de la portion tubulaire 70.  Referring to Figures 7, 8 and 9, it is found that the mask has a locking system unlockable from the tuba to the body. This locking system comprises, in this example, a tab 200 which extends from the first end 72 of the tubular portion 70.
Par ailleurs, la languette 200 est munie d'une portion de fixation Furthermore, the tongue 200 is provided with a fixing portion
202. 202.
Le cerclage 24 comporte, par ailleurs, un sommet 24a dans lequel est ménagée une ouverture 204. Cette ouverture 204 est traversante.  Strapping 24 has, moreover, a top 24a in which is formed an opening 204. This opening 204 is through.
La portion de fixation 202 de la languette 200 est conformée pour être reçue dans l'ouverture 204 afin de verrouiller le tuba au corps.  The attachment portion 202 of the tongue 200 is shaped to be received in the opening 204 to lock the tuba to the body.
A l'aide des figures 8 et 9, on comprend que la languette est déformable de sorte que lors de l'engagement du tuba 18 avec le corps 12, le connecteur sommital 106 s'engage dans le canal d'air 90 du tuba 18 et la portion de fixation 202 s'engage entre la partie supérieure du cerclage 24 et le connecteur sommital, jusqu'à ce que la portion de fixation soit engagée dans l'ouverture 204.  With the help of Figures 8 and 9, it is understood that the tongue is deformable so that during the engagement of the tuba 18 with the body 12, the top connector 106 engages in the air channel 90 of the tuba 18 and the attachment portion 202 engages between the upper portion of the strapping 24 and the top connector, until the attachment portion is engaged in the opening 204.
On comprend donc que lorsque le tuba est monté au corps, au moins une partie de la languette est disposée en-dessous du cerclage. Autrement dit, la languette s'engage par le dessous du cerclage. Comme on le constate sur la figure 9, la languette est engagée entre le connecteur sommital 106 et le cerclage. It is therefore understood that when the tuba is mounted to the body, at least a portion of the tongue is disposed below the strapping. In other words, the tongue engages from below the strapping. As it is noted in Figure 9, the tongue is engaged between the top connector 106 and the strapping.
Par ailleurs, la portion de fixation 202 constitue également un bouton poussoir agencé pour permettre à un utilisateur de dégager la portion de fixation de l'ouverture de façon à séparer le tuba du corps.  Furthermore, the attachment portion 202 is also a push button arranged to allow a user to release the fixing portion of the opening so as to separate the tuba of the body.
Pour ce faire, l'utilisateur appuie sur la portion de fixation de sorte à déformer la languette tout en tirant sur le tuba, afin de faire passer la portion de fixation sous le cerclage. La portion de fixation 202 est constituée d'un renflement 206, qui présente une forme biseautée qui est conformée pour venir s'engager dans l'ouverture lors que le tuba est monté au corps.  To do this, the user presses the attachment portion so as to deform the tongue while pulling on the tuba, in order to pass the fixing portion under the banding. The fixing portion 202 consists of a bulge 206, which has a beveled shape which is shaped to engage in the opening when the tuba is mounted to the body.
Dans cet exemple, le renflement présente une forme annulaire. In this example, the bulge has an annular shape.
Par ailleurs, la languette 200 présente une portion de réception 208 qui est disposée entre la portion de fixation 202 et la portion tubulaire 70 du tuba. La portion de réception est conformée pour recevoir une partie 24b du cerclage 24 formant butée lorsque le tuba est monté au corps. Furthermore, the tongue 200 has a receiving portion 208 which is disposed between the fastening portion 202 and the tubular portion 70 of the tuba. The receiving portion is shaped to receive a portion 24b of the strapping 24 forming a stop when the tuba is mounted to the body.
Par ailleurs, la portion de réception 208 et la partie formant butée du cerclage 24 sont engagées ensemble par coopération de forme lorsque le tuba est monté au corps, ce qui a pour effet d'empêcher un déverrouillage intempestif du tuba.  Furthermore, the receiving portion 208 and the abutment portion of the strapping 24 are engaged together by shape cooperation when the snorkel is mounted to the body, which has the effect of preventing inadvertent unlocking of the snorkel.
Par ailleurs, la portion de réception 208 comporte deux nervures 210, 212 disposées de part et d'autre de ladite portion de réception 208, ces nervures s'étendant entre la première extrémité de la portion tubulaire et la portion de fixation, et coopérant avec deux rainures 214, 216 - visibles sur la figure 10 - du cerclage lorsque le tuba est monté au corps. L'intérêt est d'assurer la stabilité du tuba lorsqu'il est monté au corps.  Furthermore, the receiving portion 208 comprises two ribs 210, 212 disposed on either side of said receiving portion 208, these ribs extending between the first end of the tubular portion and the fixing portion, and cooperating with two grooves 214, 216 - visible in Figure 10 - strapping when the tuba is mounted to the body. The interest is to ensure the stability of the snorkel when mounted to the body.
Par ailleurs, le connecteur sommital 106 comporte un renfoncement 220 qui est situé en-dessous de la portion de fixation lorsque le tuba est monté au corps. Ce renfoncement accueille la languette déformée pendant l'engagement du tuba sur le corps. Elle permet également de laisser un espace pour la déformation de la languette lors du désengagement du tuba par rapport au corps.  On the other hand, the uppermost connector 106 has a recess 220 which is located below the attachment portion when the tuba is mounted to the body. This recess receives the deformed tongue during the engagement of the snorkel on the body. It also allows space for deformation of the tongue when disengaging the tuba relative to the body.
Enfin, on constate que le masque comporte en outre un joint d'étanchéité 250 disposé entre le corps et le tuba. Ce joint d'étanchéité 250 est reçu dans une gorge annulaire 252 ménagée sur connecteur sommital de la visière. Finally, it is found that the mask further comprises a seal 250 disposed between the body and the tuba. This seal 250 is received in an annular groove 252 formed on top connector of the visor.
En se référant aux figures 11 et 12, on va décrire un support de fixation pour un accessoire, par exemple une caméra. Ce support de fixation est de préférence amovible.  Referring to Figures 11 and 12, there will be described a mounting bracket for an accessory, for example a camera. This fixing support is preferably removable.
Le support de fixation 300 présente une portion de montage 302 à proprement parlé qui présente un organe de fixation 304 cylindrique, connu par ailleurs, pour recevoir une caméra. Ce support de fixation 300 est monté de façon amovible au corps du masque.  The mounting bracket 300 has a mounting portion 302 itself which has a cylindrical fixing member 304, also known to receive a camera. This mounting bracket 300 is removably mounted to the mask body.
Le support de fixation 300 comporte par ailleurs deux pattes 306, The fixing support 300 also has two lugs 306,
308 qui se terminent par deux ailes 310 qui sont conformées pour coopérer avec le cerclage du corps afin de bloquer le support de fixation par rapport au corps. 308 which end with two wings 310 which are shaped to cooperate with the strapping of the body to block the mounting bracket relative to the body.
Le support de fixation 300 comporte également une portion de liaison 312 qui s'étend entre les pattes 306,308 et l'organe de fixation 304. Cette portion de liaison présente une forme de crochet conformé pour s'appuyer sur la visière lorsque le support est monté au masque, grâce à quoi les ailes et la portion de liaison assurent l'immobilisation du support de fixation par rapport au corps. En outre, la forme de crochet est agencée de sorte que l'organe de fixation 304 se trouve sensiblement au niveau des yeux de l'utilisateur. Grâce à ce positionnement avantageux, la caméra est nécessairement immergée lorsque le corps du masque est immergé, le tuba étant hors de l'eau. Un intérêt est donc de s'assurer que la caméra filme sous l'eau et non pas la surface de l'eau.  The fixing support 300 also comprises a connecting portion 312 which extends between the tabs 306, 308 and the fixing member 304. This connecting portion has a shaped hook shaped to rest on the visor when the support is mounted. to the mask, whereby the wings and the connecting portion ensure the immobilization of the mounting bracket relative to the body. In addition, the hook shape is arranged so that the fastener 304 is substantially at the level of the eyes of the user. Thanks to this advantageous positioning, the camera is necessarily immersed when the body of the mask is immersed, the snorkel being out of the water. An interest is therefore to ensure that the camera films underwater and not the surface of the water.
Le masque de plongée comporte par ailleurs un dispositif de maintien 400, visible sur les figures 1B, 2 et 7, qui comporte un élément d'attache central 402 située entre deux éléments d'attache latéraux 404, 406.  The diving mask further comprises a holding device 400, visible in FIGS. 1B, 2 and 7, which comprises a central fastening element 402 located between two lateral fastening elements 404, 406.
L'élément d'attache central 402 se présente sous la forme d'un champignon dont la tête 403 est conformée pour être introduite successivement dans un premier trou 408 puis dans un second trou 410 juxtaposé au premier trou, ménagés à proximité de la première extrémité de la portion tubulaire du tuba. Comme on le constate sur la figure 7, le premier trou 408 présente un diamètre supérieur à celui du second trou 410. La tête 403 de l'élément d'attache central 402 présente un diamètre inférieur à celui du premier trou mais supérieur à celui du second trou. On comprend donc que l'élément d'attache central 402 est solidarisé du tuba lorsque la tête est amenée dans le second trou 410. The central fastening element 402 is in the form of a mushroom whose head 403 is shaped to be introduced successively into a first hole 408 and then into a second hole 410 juxtaposed with the first hole, formed near the first end. tubular portion of the tuba. As can be seen in FIG. 7, the first hole 408 has a larger diameter than the second hole 410. The head 403 of the central fastening element 402 has a diameter smaller than that of the first hole but greater than that of the second hole. It is therefore understood that the central fastening element 402 is secured to the tuba when the head is fed into the second hole 410.
Comme on le comprend à l'aide des figures 1B et 2, les éléments d'attache latéraux 404, 406 présentent la forme de tiges qui sont destinées à être insérées dans des ouvertures 412,414 ménagées dans le cadre, de préférence dans le cerclage, afin de solidariser le dispositif de maintien par rapport au corps.  As can be understood from FIGS. 1B and 2, the lateral fastening elements 404, 406 are in the form of rods which are intended to be inserted into openings 412, 414 in the frame, preferably in the strapping, so as to to secure the holding device relative to the body.
On comprend donc que le dispositif de maintien 400 a pour fonction de maintenir le tuba au corps, même lorsque la portion tubulaire du tuba est découplée fluidiquement du connecteur sommital, ce qui permet d'éviter d'égarer le tuba.  It is therefore understood that the holding device 400 has the function of maintaining the tuba to the body, even when the tubular portion of the tuba is fluidly decoupled from the summit connector, which makes it possible to avoid mislaying the tuba.
Le dispositif de maintien 400 est préférentiellement réalisé dans un matériau souple de type caoutchouc.  The holding device 400 is preferably made of a flexible material of the rubber type.
