Abstract
Description
La présente invention concerne une valve atmosphérique s'adaptant par emboîtage sur les tubas conventionnels de plongée sous-marine permettant de purger l'air et l'eau en situation en situation immergée évitant l'introduction d'eau par l'extrémité du tube. The present invention relates to an atmospheric valve adaptable by fitting onto conventional scuba diving snorkels making it possible to purge air and water in a submerged situation avoiding the introduction of water by the end of the tube.
Les nombreux tubas proposés au public, censés éviter l'introduction d'eau par l'extrémité du tube et l'absorption par l'utilisateur comportent divers dispositifs de manipulation délicate. The numerous snorkels offered to the public, supposed to avoid the introduction of water by the end of the tube and absorption by the user include various delicate handling devices.
Ma précédente invention, déposée initialement aux Etats Unis faisant l'objet du brevet N0 77 23516, concerne un tuba intégrant ùn dispositif de piègeage d'eau relié à un second dispositif de purge air et eau via un déflecteur aboutissant à une valve à clapet. My previous invention, originally filed in the United States, subject to patent No. 77 23516, relates to a snorkel incorporating a water trapping device connected to a second air and water purge device via a deflector leading to a flap valve.
Le bon fonctionnement d'un tuba de ce type est tributaire de la combinaison des multiples dispositifs décrits ci-dessus. Par ailleurs, son encombrement important, découlant de l'adjonction de ces divers dispositifs crée une résistance à l'immersion en rapport au volume d'air qu'ils intègrent. The proper functioning of a snorkel of this type is dependent on the combination of the multiple devices described above. Furthermore, its large size, resulting from the addition of these various devices creates resistance to immersion in relation to the volume of air they integrate.
La présente invention permet de remédier à ces inconvénients; elle comprte en effet un seul et unique dispositif compact, s'agissant d'une valve atmosphérique s'adaptant par simple emboitage sur les tubas conventionnels. The present invention overcomes these drawbacks; it indeed includes a single compact device, being an atmospheric valve adaptable by simple fitting on conventional tubas.
La valve est réalisée en matière plastique rigide " polyétylène", elle est composée de deux éléments emboités faisant corps par pression elle comporte : Une partie externe femelle (Fig 1) formant une cloche cylindrique au dôme applati, intégrant une butée interne limitant l'introduction de la partie mâle, présentant à sa base une épaisseur supérieure de la paroi tendant à éviter tout retrait de la partie mâle après emboîtage. The valve is made of rigid plastic "polyethylene", it is composed of two nested elements forming a body by pressure it comprises: An external female part (Fig 1) forming a cylindrical bell with flattened dome, integrating an internal stop limiting the introduction of the male part, having at its base a greater thickness of the wall tending to avoid any withdrawal of the male part after fitting.
Une partie interne mâle (Fig2) composée d'un tube intégrant une spirale à deux tours à sa périphérie, présentant à sa base un diamètre différent pour l'adaptation sur les tubas de plongée. A male internal part (Fig2) composed of a tube integrating a spiral with two turns at its periphery, having at its base a different diameter for adaptation on diving snorkels.
Dans la forme de réalisation selon la figure 1, le dôme de la cloche comporte intérieurement une protubérance conique axiale. In the embodiment according to Figure 1, the dome of the bell internally has an axial conical protuberance.
Cette configuration a pour premier effet la séparation et projection simultanée de l'eau à évacuer sur la spirale (Fig3) sans retombées à l'intérieur tu tube lors de l'opération classique de purge de l'eau ayant pénétré par l'embouchure du tuba. This configuration has for first effect the separation and simultaneous projection of the water to be evacuated on the spiral (Fig3) without fallout inside the tube during the classic operation of purging the water having penetrated by the mouth of the tuba.
Cette configuration a pour deuxième effet une répartition et projection dynamique de l'air vers la spirale excluant toute compression sous le dôme lors de l'opération de soufflage. The second effect of this configuration is a dynamic distribution and projection of air towards the spiral, excluding any compression under the dome during the blowing operation.
Dans la forme de réalisation selon la figure 4, la spirale agit en compensateur d'inclinaison évitant l'introduction de l'eau par l'extrémité du tube. In the embodiment according to Figure 4, the spiral acts as a tilt compensator preventing the introduction of water through the end of the tube.
Le dispositif selon l'invention est particulièrement destiné à l'utilisation sur les tubas de plongée sous-marine. The device according to the invention is particularly intended for use on scuba diving snorkels.
