Description

MASQUE DE PLONGEE PERMETTANT L'EQUILIBRAGE DES PRESSIONS AU NIVEAU DES OREILLES  DIVE MASK FOR EYE PRESSURE BALANCING
Arrière-plan de l'invention Background of the invention
La présente invention concerne le domaine des masques de plongée, et notamment les masques utilisées 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-Masque-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 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 is that you can not talk 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, et de manière générale à tout air chaud produit dans la chambre de vision sans être renouvelé par de l'air frais.  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 nose of the user opens into the vision chamber located between the visor and the eyes of the user, and generally any hot air produced in the vision chamber without being renewed by fresh air.
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 3 020 620 B1 propose un masque de plongée permettant de respirer par le nez et la bouche. To remedy this drawback, the document FR 3 020 620 B1 proposes a diving mask for breathing through the nose and mouth.
Cependant ce type de masque-tuba amélioré ne permet pas à l'utilisateur de compenser la pression lorsqu'il descend en profondeur. Pour réaliser cette opération, il est nécessaire de pincer le nez afin de boucher les narines et équilibrer les pressions au niveau de chacune des oreilles (en particulier entre l'oreille externe et l'oreille moyenne d'une oreille donnée).  However this type of improved snorkel mask does not allow the user to compensate the pressure when it goes down deep. To perform this operation, it is necessary to pinch the nose to block the nostrils and balance the pressures at each ear (especially between the outer ear and the middle ear of a given ear).
Il existe ainsi un besoin pour un masque-tuba permettant de respirer indifféremment par le nez et/ou la bouche, éviter la formation de buée dans le compartiment vision et permettant de réaliser autant de fois que nécessaire une opération d'équilibrage des pressions. There is thus a need for a snorkel mask to breathe indifferently through the nose and / or the mouth, to prevent the formation of mist in the vision compartment and allowing to carry out as many times as necessary a pressure balancing operation.
Il existe également un besoin pour un tel masque-tuba qui soit léger, facile à positionner sur le visage de l'utilisateur, et confortable.  There is also a need for such a snorkel mask which is lightweight, easy to position on the face of the user, and comfortable.

De plus, la jupe comprend une partie auxiliaire nasale, dans le prolongement de la cloison, ladite partie auxiliaire nasale comprend un logement auxiliaire recevant le nez et configuré de manière à permettre le pincement du nez de l'utilisateur.  In addition, the skirt comprises a nasal auxiliary portion, in the extension of the partition, said nasal auxiliary portion comprises an auxiliary housing receiving the nose and configured to allow the pinching of the nose of the user.
On comprend que la visière est agencée en sorte de ne pas recouvrir le nez, et éventuellement la bouche de l'utilisateur, de sorte que l'utilisateur peut pincer son nez, en pinçant le logement principal de la partie principale nasale. On comprend que le tuba est en connexion fluidique avec la chambre supérieure. Dans ce but, le corps comporte avantageusement un dispositif d'entrée d'air frais qui communique fluidiquement avec le tuba et avec la chambre d'air supérieure. It is understood that the visor is arranged so as not to cover the nose, and possibly the mouth of the user, so that the user can pinch his nose, by pinching the main housing of the main nasal part. It is understood that the tuba is in fluid connection with the upper chamber. For this purpose, the body advantageously comprises a fresh air inlet device which fluidly communicates with the tuba and with the upper air chamber.
De préférence, le bord supérieur de la partie principale nasale comprend une projection ayant un décochement, notamment en forme de L, agencé en sorte de recevoir le bord inférieur de la partie supérieure de la visière. Dans ce cas, le bord supérieur de la partie principale nasale est en prise avec la face supérieure ou inférieure, et la tranche du bord inférieur de la partie supérieure de la visière.  Preferably, the upper edge of the main nasal portion comprises a projection having a notch, in particular L-shaped, arranged to receive the lower edge of the upper part of the visor. In this case, the upper edge of the nasal main part is engaged with the upper or lower face, and the edge of the lower edge of the upper part of the visor.
Le bord supérieur de la partie principale nasale peut comprendre, alternativement, une projection en forme de U recevant le bord inférieur de la partie supérieure de la visière. Dans ce cas, le bord supérieur de la partie principale nasale est en prise avec les faces supérieure et inférieure, et la tranche, du bord inférieur de la partie supérieure de la visière.  The upper edge of the nasal main portion may alternatively comprise a U-shaped projection receiving the lower edge of the upper portion of the visor. In this case, the upper edge of the nasal main portion is engaged with the upper and lower faces, and the edge, of the lower edge of the upper portion of the visor.
De préférence, la jupe souple est fixée à la visière. De plus, la visière est au moins partiellement transparente. De préférence, la visière présente une portion plane transparente qui se situe en regard de la chambre supérieure.  Preferably, the flexible skirt is attached to the visor. In addition, the visor is at least partially transparent. Preferably, the visor has a transparent flat portion which is opposite the upper chamber.
De préférence, la jupe souple comprend une lèvre d'étanchéité agencée pour venir en appui sur le visage de l'utilisateur.  Preferably, the flexible skirt comprises a sealing lip arranged to bear on the face of the user.
De préférence, la jupe souple (et donc ladite cloison) et la partie principale nasale, et éventuellement la partie auxiliaire nasale définit ci-après, sont chacune dans un matériau polymérique, lesquels matériaux peuvent être différents ou identiques (de par leurs compositions, leurs esthétiques (formes, couleurs,...), leurs propriétés mécaniques (résistance mécanique en traction, allongement à rupture en traction,...).  Preferably, the flexible skirt (and thus said septum) and the main nasal part, and optionally the nasal auxiliary part defined hereinafter, are each in a polymeric material, which materials may be different or identical (by their compositions, their aesthetic (shapes, colors, ...), their mechanical properties (tensile strength, tensile elongation, ...).
Ledit matériau polymérique présente de préférence un allongement à rupture, notamment en traction, supérieur ou égal à 100%, encore de préférence supérieur ou égal à 300%, préférentiellement supérieur ou égal à 400%.  Said polymeric material preferably has an elongation at break, especially in tension, greater than or equal to 100%, more preferably greater than or equal to 300%, preferably greater than or equal to 400%.
De préférence, le matériau polymérique est un élastomère.  Preferably, the polymeric material is an elastomer.
La jupe souple, la partie principale nasale, et éventuellement la partie auxiliaire nasale, sont ainsi déformables et se conforment souplement, d'une part, au visage de l'utilisateur améliorant ainsi son confort, et d'autre part, aux parties du masques rigides ou semi-rigides ce qui améliore l'étanchéité.  The flexible skirt, the main nasal part, and possibly the nasal auxiliary part, are thus deformable and conform smoothly, on the one hand, to the face of the user thus improving his comfort, and on the other hand, to the parts of the masks rigid or semi-rigid which improves the sealing.
Dans une variante, le dispositif d'échappement d'air expiré comporte un premier canal d'échappement d'air expiré qui s'étend le long d'un des deux bords latéraux du corps, en particulier des premier et second canaux d'air expiré s'étendant de part et d'autre des deux bords latéraux de la visière, la jupe souple ayant une première partie latérale qui recouvre le premier canal d'échappement d'air expiré, et éventuellement une seconde partie latérale qui recouvre le second canal d'échappement d'air expiré. Alternatively, the expired air exhaust device has a first expired air exhaust channel that extends along one of the two lateral edges of the body, in particular first and second exhaled air channels extending on either side of the two lateral edges of the visor, the flexible skirt having a first lateral part which covers the first exhaust channel of exhaled air, and possibly a second lateral portion which covers the second exhaled air outlet channel.
Le premier canal d'échappement d'air, et éventuellement le second canal d'échappement d'air, compren(d)(nent) de préférence deux parois latérales et une paroi de fond, en particulier lesdites parois forme un U en coupe transversale dudit premier canal, et éventuellement dudit second canal.  The first air exhaust duct, and possibly the second exhaust duct, preferably comprises two side walls and a bottom wall, in particular said walls forming a U in cross-section. said first channel, and possibly said second channel.
Le premier canal, et éventuellement le second canal, peu(t)(vent) ainsi être constitué(s) (chacun) de deux nervures adjacentes, qui font saillies depuis un premier bord latéral de la visière, et éventuellement un second bord latéral de la visière respectivement.  The first channel, and possibly the second channel, little (t) (wind) and be (s) (each) of two adjacent ribs, which project from a first side edge of the visor, and optionally a second side edge of the visor respectively.
Le premier canal d'échappement d'air expiré, et éventuellement le second canal d'échappement d'air expiré, peu(t)(vent) former une seule pièce avec la visière, encore de préférence, les deux Qeux de deux) nervures adjacentes forment une seule pièce avec la visière.  The first exhaled air exhaust duct, and possibly the second exhaled air exhaust duct, may (t) (wind) form a single piece with the visor, more preferably, the two (two) ribs adjacent ones form a single piece with the visor.
Le premier canal d'échappement d'air expiré, et éventuellement le second canal d'échappement d'air expiré, peu(t)(vent) être une (des) pièce(s) différente(s) de la visière, solidarisée(s), de manière amovible ou non, à l'un des deux bords (ou aux deux bords) latéraux de la visière. Ladite pièce ayant en coupe transversale une forme de U.  The first exhaled air outlet channel, and possibly the second exhaled air exhaust duct, may be (a) (wind) be a different part (s) of the visor, secured ( s), removably or not, at one of the two edges (or both sides) of the visor. Said piece having a cross-sectional shape of U.
La première partie latérale, et éventuellement la seconde partie latérale, de la jupe comporte un bord latéral dans lequel est engagé le premier (ou second) canal d'échappement d'air afin d'empêcher l'eau de pénétrer dans le premier (ou second) canal d'échappement d'air.  The first lateral part, and possibly the second lateral part, of the skirt comprises a lateral edge in which the first (or second) air exhaust channel is engaged in order to prevent the water from entering the first (or second) air exhaust channel.
Pour ce faire, le bord latéral de la jupe comporte une paroi supérieure et au moins une paroi latérale, de préférence deux parois latérales. La ou lesdites paroi(s) latérale(s) flanque(nt) la ou les deux nervure(s) du premier (ou second) canal d'échappement tandis que la paroi supérieure couvre le premier (ou second) canal d'échappement afin d'assurer l'étanchéité.  To do this, the lateral edge of the skirt has an upper wall and at least one side wall, preferably two side walls. The at least one side wall (s) flank the at least one rib (s) of the first (or second) exhaust channel while the top wall covers the first (or second) exhaust channel so that to seal.
De préférence, ledit 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.  Preferably, said 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.
Dans un mode de réalisation, le corps du masque comporte en outre un cerclage, en particulier rigide ou semi-rigide, qui entoure la visière. De préférence, le bord périphérique de la jupe (en particulier la première partie latérale et/ou la seconde partie latérale de la jupe) est serré entre le cerclage et le premier (ou second) canal d'échappement d'air expiré. Ceci a pour effet d'empêcher que le bord périphérique de la jupe ne se désaccouple du premier (ou second) canal d'échappement d'air expire. In one embodiment, the body of the mask further comprises a strapping, in particular rigid or semi-rigid, which surrounds the visor. Preferably, the peripheral edge of the skirt (in particular the first lateral portion and / or the second lateral portion of the skirt) is tightened between the strapping and the first (or second) expired air exhaust channel. This has the effect of preventing the peripheral edge of the skirt from uncoupling from the first (or second) exhaust air channel.
De préférence, le premier canal d'échappement d'air expiré, et éventuellement le second canal d'échappement d'air expiré, compren(d)(nnent) une portion d'extrémité inférieure comportant au moins une ouverture débouchant dans la chambre inférieure, et éventuellement une portion d'extrémité supérieure en connexion fluidique avec le tuba.  Preferably, the first exhaled air outlet channel, and optionally the second exhaled air outlet channel, comprises (d) (nn) a lower end portion having at least one opening opening into the lower chamber , and possibly an upper end portion in fluid connection with the tuba.
Dans un mode de réalisation, le dispositif d'échappement d'air expire comprend un second canal d'échappement d'air expiré équivalent au premier canal d'échappement d'air expiré. Les premier et second canaux d'air expiré sont de préférence disposés de part et d'autre du plan de symétrie du masque.  In one embodiment, the air exhaust device expires includes a second exhaled air exhaust channel equivalent to the first expired air exhaust channel. The first and second expired air channels are preferably arranged on either side of the plane of symmetry of the mask.
On comprend dans le présent texte par "plan de symétrie (S) du masque" tout plan du masque passant sensiblement par le plan de coupe sagittale du visage de l'utilisateur.  It is understood in the present text by "plane of symmetry (S) of the mask" any plane of the mask substantially passing through the sagittal section plane of the face of the user.
Dans une variante, la visière comprend une partie inférieure, et la partie principale nasale comprend un bord inférieur solidarisé de manière étanche au bord supérieur de la partie inférieure de la visière.  In a variant, the visor comprises a lower part, and the main nasal part comprises a lower edge sealed to the upper edge of the lower part of the visor.
De préférence, la partie inférieure de la visière recouvre au moins en partie le menton de l'utilisateur, et encore de préférence la bouche.  Preferably, the lower part of the visor covers at least part of the chin of the user, and preferably the mouth.
Avantageusement, la partie principale nasale s'étend, au moins en partie, entre le bord inférieur de la partie supérieure de la visière, et le bord supérieur de la partie inférieure de la visière.  Advantageously, the main nasal portion extends, at least in part, between the lower edge of the upper part of the visor, and the upper edge of the lower part of the visor.
La partie principale nasale n'est donc pas plaquée, collée sur le visage de l'utilisateur, en particulier sur la bouche ou le nez ce qui facilite la respiration.  The nasal main part is not plated, stuck on the user's face, especially on the mouth or nose which facilitates breathing.
Dans une variante, la visière comprend une ouverture centrale ayant un bord supérieur et un bord inférieur entre lesquels s'étend au moins en partie la partie principale nasale.  Alternatively, the visor comprises a central opening having an upper edge and a lower edge between which extends at least in part the main nasal portion.

Cette disposition facilite la respiration par la bouche puisque la partie principale nasale n'est pas plaquée contre cette dernière. Dans une variante, la partie principale nasale comprend au moins une projection latérale se projetant selon un coté du plan de symétrie S du masque, de préférence deux projections latérales se projetant de part et d'autre du plan de symétrie S du masque. This arrangement facilitates breathing through the mouth since the nasal main part is not pressed against it. In a variant, the main nasal portion comprises at least one lateral projection projecting along one side of the plane of symmetry S of the mask, preferably two lateral projections projecting on either side of the symmetry plane S of the mask.
De préférence, la ou lesdites projection(s) latérale(s) s'étend(ent) sous le logement recevant au moins en partie le nez.  Preferably, said projection (s) side (s) extends (ent) under the housing receiving at least partly the nose.

Dans une variante, ladite au moins une projection latérale de la partie principale nasale comprend une extrémité distale solidarisée de manière étanche selon un bord latéral de la visière, en particulier ledit bord latéral est disposé entre les parties supérieure et inférieure de la visière.  Alternatively, said at least one lateral projection of the nasal main portion comprises a distal end sealingly secured along a side edge of the visor, in particular said side edge is disposed between the upper and lower portions of the visor.
L'extrémité latérale peut comprendre une projection en forme de U ou de L telle que définie ci-dessus en référence à la projection disposée selon le bord supérieur et/ou le bord inférieure de la partie principale nasale.  The lateral end may comprise a U-shaped or L-shaped projection as defined above with reference to the projection disposed along the upper edge and / or the lower edge of the main nasal portion.
De préférence, le masque comprend une première projection latérale comprenant une première extrémité distale, et une seconde projection latérale comprenant une seconde extrémité distale. La première extrémité latérale est solidarisée de manière étanche selon un premier bord latéral de la visière, et la seconde projection latérale est solidarisée de manière étanche selon un second bord latérale de la visière.  Preferably, the mask comprises a first lateral projection comprising a first distal end, and a second lateral projection comprising a second distal end. The first lateral end is secured in a sealed manner along a first lateral edge of the visor, and the second lateral projection is sealed integrally along a second lateral edge of the visor.
Encore de préférence, les premier et second bords latéraux de la visière sont disposés de part et d'autre du plan de symétrie S du masque.  Still preferably, the first and second lateral edges of the visor are arranged on either side of the plane of symmetry S of the mask.
De préférence, les premier et second bords latéraux sont disposés entre les parties supérieure et inférieure de la visière.  Preferably, the first and second side edges are disposed between the upper and lower portions of the visor.
Dans une variante, la partie principale nasale, et/ou la partie auxiliaire nasale définie ci-après, compren(d)(nent) une face externe et une face interne, la face interne étant orientée en regard de la chambre de respiration, et la partie principale nasale, et/ou la partie auxiliaire nasale définie ci-après, compren(d)(nent) deux protubérances se projetant de ladite face interne et disposées de part d'autre du plan de symétrie S du masque.  In a variant, the main nasal portion, and / or the nasal auxiliary portion defined below, comprises (d) (nent) an external face and an internal face, the internal face being oriented opposite the breathing chamber, and the nasal main part, and / or the nasal auxiliary part defined below, comprises (d) (n) two protuberances projecting from said internal face and disposed on either side of the symmetry plane S of the mask.
La face externe de la partie principale nasale débouche à l'extérieur du masque, elle est donc accessible à l'utilisateur lorsque le masque est porté.  The outer face of the main nasal portion opens out of the mask, so it is accessible to the user when the mask is worn.
Les deux protubérances de la partie principale nasale, et/ou de la partie auxiliaire nasale définie ci-après, sont agencées pour délimiter entre-elles ledit logement principale, et/ou ledit logement auxiliaire défini ci-après, recevant au moins en partie le nez. Les deux protubérances de la partie principale nasale, et/ou de la partie auxiliaire nasale définie ci-après, comprennent des première et seconde parois latérales entre lesquelles les parois correspondantes du nez sont logées. The two protuberances of the main nasal part, and / or of the nasal auxiliary part defined below, are arranged to delimit between them said main housing, and / or said auxiliary housing defined below, receiving at least partly the nose. The two protuberances of the main nasal portion, and / or the nasal auxiliary portion defined below, comprise first and second side walls between which the corresponding walls of the nose are housed.
Les deux protubérances ont de préférence une forme sensiblement d'aile, en particulier en forme de triangle dans leur plan de coupe longitudinal.  The two protuberances preferably have a substantially wing-shaped shape, in particular in the form of a triangle in their longitudinal section plane.
De préférence, le logement principal, et/ou le logement auxiliaire défini ci-après, recevant le nez ne comprend pas de paroi inférieure venant contre le bord inférieure du nez de l'utilisateur ce qui facilite la respiration.  Preferably, the main housing, and / or the auxiliary housing defined below, receiving the nose does not comprise a lower wall against the lower edge of the nose of the user which facilitates breathing.
De préférence, le logement principal, et/ou le logement auxiliaire défini ci-après, est/sont en communication fluidique avec la chambre inférieure.  Preferably, the main housing, and / or the auxiliary housing defined below, is / are in fluid communication with the lower chamber.
Dans une variante, au moins l'une des deux protubérances présente une épaisseur croissante de sa portion supérieure vers sa base.  In a variant, at least one of the two protuberances has an increasing thickness from its upper portion to its base.
Avantageusement, la base étant plus épaisse que la partie supérieure, le pincement du nez est facilité en pressant les deux bases des deux protubérances contre les narines.  Advantageously, the base being thicker than the upper part, the pinching of the nose is facilitated by pressing the two bases of the two protuberances against the nostrils.
Dans une variante, la partie principale nasale, et/ou la partie auxiliaire nasale définie ci-après, compren(d)(nent) une face externe et une face interne, la face interne étant orientée en regard de la chambre de respiration, et la partie principale nasale, et/ou la partie auxiliaire nasale définie ci-après, compren(d)(nent), selon sa face externe, deux renfoncements disposés de part et d'autre du(des) logement(s) principal, et/ou auxiliaire, pour le nez.  In a variant, the main nasal portion, and / or the nasal auxiliary portion defined below, comprises (d) (nent) an external face and an internal face, the internal face being oriented opposite the breathing chamber, and the nasal main part, and / or the nasal auxiliary part defined below, comprises (d) (n), according to its external face, two recesses arranged on either side of the (or) main housing (s), and / or auxiliary, for the nose.

Dans une variante, la jupe et la partie principale nasale sont deux pièces distinctes.  In a variant, the skirt and the nasal main part are two separate pieces.
Cette disposition facilite la fabrication du masque selon l'invention.  This arrangement facilitates the manufacture of the mask according to the invention.
Dans une variante, la partie auxiliaire nasale comprend une portion de platine auxiliaire s'étendant sous le logement auxiliaire recevant au moins en partie le nez, ladite platine étant solidarisée à la visière, en particulier à la partie inférieure de la visière.  In a variant, the nasal auxiliary portion comprises an auxiliary platinum portion extending under the auxiliary housing receiving at least part of the nose, said plate being secured to the visor, in particular to the lower part of the visor.
De préférence, la portion de platine s'étend sur la face interne de la partie inférieure de la visière.  Preferably, the platinum portion extends on the inner face of the lower part of the visor.
Encore de préférence, le bord supérieur de la partie inférieure de la visière est disposé entre la portion de platine de la partie principale nasale et la portion de platine de la partie auxiliaire nasale.  Still preferably, the upper edge of the lower portion of the visor is disposed between the platinum portion of the nasal main portion and the platinum portion of the nasal portion.
De préférence, la platine auxiliaire est solidarisée à la partie inférieure de la visière à l'aide d'une pièce de fixation rigide ou semi-rigide solidarisée, en particulier bouterollée ou clippée, à la partie inférieure de la visière, la platine auxiliaire étant disposée au moins en partie entre ladite pièce de fixation et la partie inférieure de la visière.  Preferably, the auxiliary plate is secured to the lower part of the visor with the aid of a solid or semi-rigid fastener fastened, in particular riveted or clipped, to the lower part of the visor, the auxiliary plate being disposed at least partially between said fastener and the lower portion of the visor.
Avantageusement, cette pièce de fixation permet de solidariser la partie auxiliaire nasale à la visière de manière étanche. Ainsi, l'air expiré par le nez et/ou la bouche ne s'écoule pas vers la chambre supérieure pour la vision.  Advantageously, this fastener makes it possible to secure the nasal auxiliary part to the visor in a sealed manner. Thus, the air exhaled by the nose and / or mouth does not flow to the upper chamber for vision.
De préférence, la pièce de fixation rigide a une forme sensiblement en V, encore de préférence la pointe du V est orientée vers la partie inférieure de la visière.  Preferably, the rigid fastener has a shape substantially V, more preferably the tip of the V is oriented towards the lower part of the visor.

Dans une variante, la partie principale nasale est dans un matériau polymérique différent ou identique du matériau polymérique de la partie principale auxiliaire nasale.  In a variant, the nasal main part is in a different or identical polymeric material of the polymeric material of the main nasal auxiliary part.
Le matériau polymérique de la partie principale nasale peut être différent du matériau polymérique de la partie principale auxiliaire nasale de par sa nature, son épaisseur, son esthétique (couleur(s), motif(s), relief(s) ou non) ou encore sa dureté, notamment sa dureté shore A.  The polymeric material of the nasal main part may be different from the polymeric material of the main nasal auxiliary part by its nature, its thickness, its aesthetics (color (s), pattern (s), relief (s) or not) or its hardness, especially its hardness shore A.
Le matériau polymérique peut être un polymère de silicone ou un élastomère de type SEBS (styrène-butylène- éthylène) ou dans tout polymère équivalent.  The polymeric material may be a silicone polymer or an elastomer of SEBS (styrene-butylene-ethylene) type or any equivalent polymer.
Dans un mode de réalisation, la partie principale nasale est dans un matériau polymérique ayant une dureté Shore A supérieure ou égale à la dureté Shore A de la partie principale auxiliaire nasale.  In one embodiment, the nasal main portion is in a polymeric material having a Shore A hardness greater than or equal to the Shore A hardness of the nasal auxiliary main portion.
Dans une variante, la partie principale nasale a une épaisseur (mm) supérieure à l'épaisseur de la partie principale auxiliaire nasale, en particulier lesdites épaisseurs sont mesuré es en dehors des logements auxiliaire et principal. Dans une variante, le bord supérieur de la partie inférieure de la visière est disposé entre la partie principale nasale et la partie auxiliaire nasale, en particulier entre la portion de platine principale et la portion de platine auxiliaire.  In a variant, the nasal main portion has a thickness (mm) greater than the thickness of the nasal auxiliary main portion, in particular said thicknesses are measured outside the auxiliary and main housing. In a variant, the upper edge of the lower part of the visor is disposed between the main nasal part and the nasal auxiliary part, in particular between the main platinum portion and the auxiliary platinum portion.
Dans une variante, la jupe et la partie principale nasale sont dans une seule et même pièce. De préférence, dans ce cas, le masque ne comprend pas de partie auxiliaire nasale.  In a variant, the skirt and the main nasal part are in one and the same room. Preferably, in this case, the mask does not include a nasal auxiliary part.
Dans une variante, la jupe comprend au moins des première et seconde pièces distinctes, une première pièce assurant l'étanchéité du ou des premier et/ou second canal(aux) d'échappement d'air et contribuant à l'étanchéité avec le visage de l"utilisateur, et une seconde pièce assurant l'étanchéité avec le visage de l'utilisateur, notamment comprenant la lèvre d'étanchéité, la seconde pièce comprend la partie auxiliaire nasale et la cloison séparant les chambres supérieure et inférieure.  In a variant, the skirt comprises at least first and second distinct parts, a first part ensuring the sealing of the first and / or second channel (aux) of exhaust air and contributing to the tightness with the face of the user, and a second piece sealing the face of the user, including the sealing lip, the second part comprises the nasal auxiliary portion and the partition separating the upper and lower chambers.
Dans ce cas, le masque ne comprend pas de partie auxiliaire nasale. In this case, the mask does not include a nasal auxiliary part.
Dans une variante, le dispositif d'échappement d'air expiré comporte au moins une première 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 première valve anti-retour étant fermée lors d'une phase d'inspiration de l'utilisateur. In a variant, the exhaled air exhaust device comprises at least a first non-return valve arranged to allow a flow of exhaled air directed from the lower chamber to the tuba air duct during an expiration phase of the user, the first non-return valve being closed during a phase of inspiration of the user .
De préférence, la première valve anti-retour est située sur le corps du masque.  Preferably, the first non-return valve is located on the body of the mask.
De préférence, la première valve anti-retour est agencée pour obturer le dispositif d'échappement d'air expiré pendant une phase d'inspiration.  Preferably, the first non-return valve is arranged to close off the exhaust air expander device during an inspiration phase.
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 tube.  During an inspiration phase, the closing of the first non-return valve has the effect that fresh air does not flow via the air exhaust device. An interest is to avoid the inspiration of the air which has just expired and which is still in the expired air exhaust device or in the air duct of the tube.
Avantageusement, la première valve anti-retour est agencée pour obturer ladite au moins une ouverture (du premier canal d'échappement d'air expiré) lors d'une phase d'inspiration de l'utilisateur.  Advantageously, the first non-return valve is arranged to close said at least one opening (of the first expired air exhaust channel) during a user inspiration phase.
De préférence, la première valve anti-retour comprend au moins une membrane souple située à l'intérieur du premier canal d'échappement d'air expiré, en regard de ladite ouverture.  Preferably, the first non-return valve comprises at least one flexible membrane located inside the first exhaled air outlet channel, facing said opening.
Selon un mode de réalisation, ladite au moins une membrane souple est constituée d'une partie de la jupe souple.  According to one embodiment, said at least one flexible membrane consists of a portion of the flexible skirt.
De préférence, la portion d'extrémité inférieure du premier ou second canal d'échappement d'air expiré comprend deux ouvertures adjacentes obturables par une ou des membrane(s) souple(s) de la première valve anti- retour.  Preferably, the lower end portion of the first or second exhaled air outlet channel comprises two adjacent openings closable by one or more flexible membranes of the first non-return valve.
Dans une variante de réalisation, le tuba comporte un unique conduit d'air qui est en communication fluidique avec la chambre inférieure et la chambre supérieure.  In an alternative embodiment, the tuba comprises a single air duct which is in fluid communication with the lower chamber and the upper chamber.
Cette disposition permet de simplifier la conception et la fabrication du tuba, par rapport aux tubas de l'art antérieur comportant plusieurs canaux. Avantageusement, tout le volume intérieur du tuba est disponible lors des phases d'inspiration et d'expiration ce qui permet d'augmenter sensiblement le débit d'air entrant et sortant améliorant ainsi le confort et facilitant la respiration bucco-nasale.  This arrangement simplifies the design and manufacture of the tuba, compared to tubas of the prior art with multiple channels. Advantageously, the entire internal volume of the snorkel is available during the phases of inspiration and expiration, which substantially increases the inflow and outflow of air thus improving comfort and facilitating oral 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.  The single air duct is therefore in fluid communication with the exhaled air exhaust device, and also with the fresh air inlet device.
De préférence, l'unique conduit d'air est en communication fluidique avec les premier et deuxième canaux d'échappement d'air expiré. Alternativement, le tuba mis en œuvre dans le masque selon l'invention peut comprendre plusieurs canaux bien que cela ne soit pas préféré. Preferably, the single air duct is in fluid communication with the first and second expired air exhaust channels. Alternatively, the tuba implemented in the mask according to the invention may comprise several channels, although this is not preferred.
Dans une variante, la cloison comporte au moins une valve anti-retour, notamment un clapet anti-retour, agencé(e) 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.  In a variant, the partition comprises at least one non-return valve, in particular a non-return valve, arranged to allow only a fresh air flow directed from the upper chamber to the lower chamber during a cooling phase. inspiration of the user.
On comprend que la valve anti-retour, notamment le clapet anti-retour, s'ouvre lors d'une phase d'inspiration et se ferme lors d'une phase d'expiration.  It is understood that the non-return valve, including the non-return valve, opens during an inspiration phase and closes during an expiration phase.
La valve anti-retour ou le clapet anti-retour a ainsi pour fonction d'empêcher que l'air expiré ne s'écoule vers la chambre supérieure, évitant ainsi l'apparition de buée sur la face inférieure de la partie supérieure de la visière.  The function of the non-return valve or the non-return valve is thus to prevent the exhaled air from flowing to the upper chamber, thereby preventing fogging on the underside of the upper part of the visor. .
Selon un mode de réalisation, le clapet anti-retour comporte un volet souple constitué d'une partie de la jupe souple.  According to one embodiment, the non-return valve comprises a flexible flap consisting of a portion of the flexible skirt.
De préférence, le volet souple du clapet anti-retour est constitué par une portion de la cloison.  Preferably, the flexible flap of the non-return valve is constituted by a portion of the partition.
Le volet souple est préférentiellement délimité entre un bord libre de la cloison et une découpe réalisée dans la cloison.  The flexible flap is preferably delimited between a free edge of the partition and a cut made in the partition.
Cette découpe confère au volet souple une mobilité lui permettant de se plier lors d'une phase d'inspiration de manière à ouvrir le passage et de permettre à l'air frais de rentrer dans la chambre inférieure.  This cutting gives the flexible flap a mobility allowing it to bend during an inspiration phase so as to open the passage and allow fresh air to enter the lower chamber.
De préférence, lors d'une phase d'expiration, le volet souple vient en appui contre la visière afin de fermer ledit passage.  Preferably, during an expiration phase, the flexible flap bears against the visor to close said passage.
La présente invention a également pour objet, selon un second aspect, un procédé de fabrication d'un masque de plongée, tel que défini selon l'une quelconque des variantes de réalisation définies ci-dessus en référence à un premier aspect de l'invention.  The subject of the present invention is also, according to a second aspect, a method of manufacturing a diving mask, as defined according to any one of the embodiments defined above with reference to a first aspect of the invention. .

In this specific example, the protuberances 90 and 91 each have an increasing thickness from its upper part to its base. The upper edge 22a of the lower portion 22 of the visor 20 is thus disposed between the main platen portion 35 overmolded on the outer face of the visor 20, and the auxiliary platen portion 65 attached to the inner face of the visor 20 by via the fastener 66.
La partie principale nasale 15 peut être dans un matériau polymérique différent ou identique au matériau polymérique de la partie auxiliaire nasale 60.  The nasal main portion 15 may be in a polymeric material different from or identical to the polymeric material of the nasal auxiliary portion 60.
Avantageusement, le dispositif d'échappement d'air expiré 80 comporte au moins une première valve anti-retour 43 agencée pour autoriser un écoulement d'air expiré dirigé de la chambre inférieure 50 vers le conduit d'air 72 du tuba 70 lors d'une phase d'expiration de l'utilisateur, la première valve anti-retour 43 étant fermée lors d'une phase d'inspiration de l'utilisateur.  Advantageously, the exhaled air exhaust device 80 comprises at least a first non-return valve 43 arranged to allow a flow of exhaled air directed from the lower chamber 50 to the air duct 72 of the tuba 70 when a phase of expiration of the user, the first non-return valve 43 being closed during a phase of inspiration of the user.
De préférence, la première valve anti-retour 43 comprend une membrane souple 142 qui, dans cet exemple précis, est constituée d'une portion de la jupe souple 30. Tel que cela est visible à la figure 6, la première partie latérale du bord périphérique 124 de la jupe 30 comporte une paroi supérieure 126 et deux parois latérales dont seule la paroi latérale 128 est clairement visible. Les parois latérales, dont la paroi latérale 128, flanquent les deux nervures, dont la nervure 105 visible, du premier canal d'échappement d'air expiré 81 afin d'assurer l'étanchéité. La membrane souple 142 se présente sous la forme d'une portion sensiblement rectangulaire qui fait saillie depuis une face interne de la paroi supérieure 126. Sur la figure 6, on a illustré en traits continus la première valve anti- retour 43 en position fermée, et en traits pointillés en position ouverte.  Preferably, the first non-return valve 43 comprises a flexible membrane 142 which, in this specific example, consists of a portion of the flexible skirt 30. As can be seen in FIG. 6, the first lateral part of the edge device 124 of the skirt 30 has an upper wall 126 and two side walls of which only the side wall 128 is clearly visible. The side walls, including the side wall 128, flank the two ribs, including the visible rib 105, the first expired air exhaust channel 81 to ensure sealing. The flexible membrane 142 is in the form of a substantially rectangular portion which projects from an inner face of the upper wall 126. In FIG. 6, the first non-return valve 43 is shown in continuous lines in the closed position. and in dotted lines in the open position.
Le dispositif d'échappement d'air expiré 80 comporte également un premier canal d'échappement d'air 81 et un second canal d'échappement d'air expiré 82 qui s'étendent le long respectivement d'un premier bord latéral 2 et d'un second bord latéral 3 du corps 10, en particulier de part et d'autre des deux bords latéraux de la visière 20.  The exhaled air exhaust device 80 also includes a first air exhaust channel 81 and a second expired air exhaust channel 82 which extend along a first side edge 2 and a first a second lateral edge 3 of the body 10, in particular on either side of the two lateral edges of the visor 20.
La première valve anti-retour 43 comporte également un siège de valve 144 agencé pour coopérer avec la membrane souple 142, le siège de valve étant intégré à la visière 20. En position fermée, la membrane souple 142 prend appui sur le siège de valve 144 pour obturer ladite au moins une ouverture ménagée dans le premier canal d'échappement d'air expiré 81.  The first non-return valve 43 also comprises a valve seat 144 arranged to cooperate with the flexible membrane 142, the valve seat being integrated with the visor 20. In the closed position, the flexible membrane 142 bears on the valve seat 144 for closing said at least one opening in the first expired air outlet channel 81.
Le dispositif d'échappement d'air expiré 80 comprend par ailleurs une deuxième valve anti-retour 160, similaire à la première valve anti-retour 43, qui est agencée pour autoriser un écoulement d'air expiré dirigé de la chambre inférieure 50 vers le conduit d'air 72 du tuba 70 lors d'une phase d'expiration de l'utilisateur. La deuxième valve anti-retour 160 fonctionne comme la première valve anti-retour 43. The exhaled air exhaust device 80 furthermore comprises a second non-return valve 160, similar to the first non-return valve 43, which is arranged to allow a flow of exhaled air directed from the lower chamber 50 towards the air duct 72 of the tuba 70 during a phase user expiration. The second non-return valve 160 functions as the first non-return valve 43.
La jupe souple 30 ayant des première 51 et seconde 52 parties latérales agencées en sorte de recouvrir de manière étanche les premier et second canaux d'échappement d'air expiré 81 et 82.  The flexible skirt 30 having first 51 and second 52 side portions arranged so as to seal the first and second expired air exhaust channels 81 and 82.
En fonctionnement, l'usager dispose le masque 1 sur son visage, qui peut comprendre des moyens de fixation tels que des sangles élastiques réglables en longueur. Lorsque l'usager inspire, l'air frais inspiré traverse le conduit 72 du tuba 70 et débouche dans la chambre supérieure 45 de vision puis passe dans le passage agencé au moyen de la valve anti-retour 55 dans la cloison 40 pour déboucher dans la chambre inférieure 50 de respiration dans laquelle se situe le nez et la bouche de l'utilisateur. La valve anti-retour 55 est configurée pour autoriser l'air inspiré de la chambre de vision 45 vers la chambre de respiration 50 et empêcher tout retour d'air expiré en sens inverse. Lors d'une phase d'expiration, le passage d'air dans la cloison 40 est obturé de sorte que l'air est forcé dans les premier et second canaux d'échappement d'air 81 et 82 disposés selon les bords latéraux 2 et 3 du corps 10, en particuliers disposés selon les bords latéraux de la visière 20 et fermés de manière étanche par les bords latéraux correspondant de la jupe souple 30.  In operation, the user has the mask 1 on his face, which may include fastening means such as elastic straps adjustable in length. When the user inspires, the fresh air inspired passes through the duct 72 of the tuba 70 and opens into the upper viewing chamber 45 and then passes into the passage arranged by means of the non-return valve 55 in the partition 40 to open into the lower breathing chamber 50 which is the nose and mouth of the user. The non-return valve 55 is configured to allow air inspired from the viewing chamber 45 to the breathing chamber 50 and prevent any return of exhaled air in the opposite direction. During an expiration phase, the passage of air in the partition 40 is closed so that the air is forced into the first and second air exhaust ducts 81 and 82 arranged along the lateral edges 2 and 3 of the body 10, in particular arranged along the lateral edges of the visor 20 and sealingly closed by the corresponding lateral edges of the flexible skirt 30.
Les premier et second canaux d'échappement d'air expiré 81 et 82 sont en liaison fluidique dans leurs parties supérieures avec le tuba 70, en particulier avec le conduit d'air unique 72.  The first and second exhaled air outlet channels 81 and 82 are in fluidic connection in their upper parts with the tuba 70, in particular with the single air duct 72.
L'air expiré est donc évacué vers le tuba 70 sans passer par la chambre supérieure de vision 45.  The exhaled air is thus evacuated towards the tuba 70 without passing through the upper viewing chamber 45.
Afin d'équilibrer les pressions, l'utilisateur pince son nez, en logeant ses doigts dans les renfoncements 31 et 32 du logement principal 16. Le logement auxiliaire 62 étant emboîté dans le logement principal 16, la pression exercée sur le logement principal 16 est transmise au logement auxiliaire 60, laquelle transmission est facilitée du fait des protubérances 5 et 6 du logement principal pressant contre les protubérances 90 et 91 du logement auxiliaire 60.  In order to balance the pressures, the user pinches his nose, by lodging his fingers in the recesses 31 and 32 of the main housing 16. The auxiliary housing 62 being fitted in the main housing 16, the pressure exerted on the main housing 16 is transmitted to the auxiliary housing 60, which transmission is facilitated due to the protuberances 5 and 6 of the main housing pressing against the protuberances 90 and 91 of the auxiliary housing 60.
L'emboîtement des logements principal 16 et auxiliaire 62 facilite le pincement du nez.  The interlocking of the main housing 16 and auxiliary 62 facilitates the pinching of the nose.
De plus, l'agencement de la visière 20 devant la bouche, ainsi que le surmoulage de la partie principale nasale 15 sur l'ouverture 4, et son agencement par rapport à la partie auxiliaire nasale 60 permettent que les parties nasales 15 et 60 ne se retrouvent pas contre la bouche de l'utilisateur ce qui facilite la respiration. In addition, the arrangement of the visor 20 in front of the mouth, as well as the overmolding of the nasal main portion 15 over the opening 4, and its arrangement relative to the nasal auxiliary portion 60 allow the nasal parts 15 and 60 do not end up against the mouth of the user which facilitates breathing.
La partie principale nasale 15 étant surmoulée au bord inférieure 21a de la partie supérieure 21 de la visière 20 d'une part, et au bord supérieur 22a de la partie inférieure 22 de la visière 20 d'autre part, et éventuellement aux bords latéraux 20d de la visière 20, il n'y a pas de risque lorsque l'utilisateur la manipule qu'elle se désolidarise de la visière 20.  The nasal main part 15 is overmolded at the lower edge 21a of the upper part 21 of the visor 20 on the one hand, and the upper edge 22a of the lower part 22 of the visor 20 on the other hand, and possibly at the lateral edges 20d of the visor 20, there is no risk when the user manipulates it that it disengages from the visor 20.
Le masque 1 selon l'invention permet ainsi de combiner les avantages d'un masque anti-buée permettant une respiration indifféremment par le nez et la bouche, tout en pouvant équilibrer les pressions au niveau des oreilles.  The mask 1 according to the invention thus makes it possible to combine the advantages of an anti-fog mask allowing a breathing indifferently by the nose and the mouth, while being able to balance the pressures at the level of the ears.
