Abstract
Description
La présente invention concerne un dispositif pour la plongée sous-marine à l'aide d'un tuba ne permettant pas à l'eau de pénétrer et permettant au plongeur de respirer un air ambiant sans gaz carbonique. The present invention relates to a device for scuba diving using a snorkel not allowing water to enter and allowing the diver to breathe ambient air without carbon dioxide.
Avec un tuba traditionnel, I'eau pénètre et le plongeur en expirant rejette le gaz carbonique qui reste à l'intérieur du tuba. With a traditional snorkel, the water enters and the diver, while exhaling, rejects the carbon dioxide which remains inside the snorkel.
Le dispositif selon l'invention permet de remédier à cet inconvénient. En effet, il comporte selon une premiére caractéristique, un tuba plastique de section elliptique avec une paroie interne formant ainsi deux tubes, I'un servant à l'aspiration, I'autre à l'expiration. Sa forme particulièrement adaptée à la forme du visage améliore la pénétration dans l'eau. La partie supérieure du tuba se termine par un embout de section carrée en matériau plus épais dirigeant l'air aspiré et l'air expiré. Sur la partie inférieure un embout en matériau souple qui se termine comme un tuba traditionnel qui se place dans la bouche. Sur cet embout inférieur se trouvent deux lèvres qui ferment deux orifices en forme de saillie, ce qui permet au plongeur de faire évacuer l'eau éventuellement entrée par maladresse. The device according to the invention overcomes this drawback. In fact, according to a first characteristic, it comprises a plastic tuba of elliptical section with an internal wall thus forming two tubes, one used for suction, the other for expiration. Its shape particularly adapted to the shape of the face improves penetration in water. The upper part of the snorkel ends with a square section end piece made of thicker material directing the air drawn in and out. On the lower part a tip in flexible material which ends like a traditional snorkel which is placed in the mouth. On this lower end are two lips which close two protruding orifices, which allows the diver to evacuate any water that may have entered by mistake.
Selon des modes particuliers de réalisation - le tuba de section elliptique constitue une partie de ce dispositif avec une paroie intérieure de même matière, formant ainsi deux tubes. According to particular embodiments - the tuba of elliptical section constitutes a part of this device with an interior wall of the same material, thus forming two tubes.
- le tuba se termine sur sa partie supérieure par un embout.- the snorkel ends on its upper part with a nozzle.
- le tuba se termine en partie inférieure par un embout en matériau souple composé d'un double clapet de deux orifices avec languettes s'ouvrant manuellement et se fermant par élasticité afin de permettre l'évacuation de l'eau et la partie de l'embout traditionnel se plaçant dans la bouche du plongeur.- the snorkel ends in the lower part with a nozzle made of flexible material composed of a double valve of two orifices with tongues opening manually and closing by elasticity in order to allow the evacuation of the water and the part of the traditional tip placed in the mouth of the diver.

Figure I represents a face section (A), a profile section (B), a cross section (C), section of the upper end piece (D), detail of the upper end piece (E), the device according to
The invention.
La figure 2 représente en coupe une variante de ce dispositif. Figure 2 shows in section a variant of this device.
La figure 3 représente le clapet inférieur.Figure 3 shows the lower valve.
La figure 4 représente les deux orifices en forme de saillie se fermant par deux languettes sur l'embout inférieur.Figure 4 shows the two protruding holes closing with two tabs on the lower end.
La figure 5 représente le système de fixation du tuba sur le masque.Figure 5 shows the system for attaching the snorkel to the mask.
En référence à ces dessins le dispositif comporte un tuba de section elliptique (1), avec une paroie interne (2) formant deux tubes un pour l'aspiration (3), I'autre pour l'expiration (4), la partie supérieure se terminant par un embout en matériau (5) qui dirige l'air aspiré et expiré, qui ne permet pas à l'eau de s'infiltrer de l'embout vers le tube (6), le tuba se termine par un embout inférieur en matériau souple (8) sur la partie inférieure de cet embout deux orifices en forme de saillie (9) se fermant par deux languettes (10) et (11), I'embout traditionnel qui se place dans la bouche (12) et un double clapet permettant l'aspiration et l'expiration (13) (détail de la figure 2). With reference to these drawings, the device comprises a tuba of elliptical section (1), with an internal wall (2) forming two tubes, one for the suction (3), the other for the expiration (4), the upper part ending in a mouthpiece made of material (5) which directs the air sucked in and out, which does not allow water to infiltrate from the mouthpiece to the tube (6), the tuba ends in a lower mouthpiece made of flexible material (8) on the lower part of this nozzle two protruding orifices (9) closing with two tabs (10) and (11), the traditional nozzle which is placed in the mouth (12) and a double valve allowing suction and expiration (13) (detail in Figure 2).
La figure 3 représente le double clapet (1) dans ses fonctions, en mouvement d'aspiration (2), en mouvement d'expiration (3). Figure 3 shows the double valve (1) in its functions, in suction movement (2), in expiration movement (3).
La figure 4 représente les deux orifices en forme de saillie (1) et (2) avec les lèpres (3) et (4) permettant l'ouverture et la fermeture de ces orifices pour évacuation de l'eau éventuellement pénétrée. Figure 4 shows the two protruding orifices (1) and (2) with the leprosy (3) and (4) allowing the opening and closing of these orifices for evacuation of the water possibly penetrated.
Le dispositif selon l'invention est particulièrement destiné à une plongée sous-marine à l'aide d'un tuba ne permettant pas à l'eau de pénétrer et permettant au plongeur de respirer un air ambiant sans gaz carbonique. The device according to the invention is particularly intended for scuba diving using a snorkel which does not allow water to enter and allows the diver to breathe ambient air without carbon dioxide.
