APPAREIL RESPIRATEUR POUR PLONGEE SOUS-MARINE A CONDUITS
MULTIPLES
La présente invention a pour objet un appareil respirateur pour plongée sous-marine à conduits multiples.BREATHING APPARATUS FOR CONDUIT DIVING
MULTIPLE
The present invention relates to a breathing apparatus for scuba diving with multiple conduits.
Il concerne l'industrie des sports nautiques et est destiné à l'équipement des adeptes de la chasse sous-marine plongeant sans bouteilles. It concerns the nautical sports industry and is intended for the equipment of the followers of underwater hunting diving without bottles.
Les appareils respirateurs pour plongée sous-marine sont constitués d'un embout buccal relié à un simple tube émergeant au-dessus de la surface de l'eau, permettant de nager avec le visage sous l'eau pour observer les fonds marins, tout en respirant normalement, et ceci sans recours à des appareillages chers et encombrants tels que scaphandres autonomes. Lorsque le nageur plonge, le tube se remplit d'eau et doit être vidé lors du retour à la surface par une forte expiration d'air. Respirators for scuba diving consist of a mouthpiece connected to a simple tube emerging above the surface of the water, allowing to swim with the face underwater to observe the seabed, while breathing normally, and this without the use of expensive and bulky equipment such as diving suits. When the swimmer dives, the tube fills with water and must be emptied when returning to the surface by a strong exhalation of air.
I1 est évident que plus la section du tube est importante, plus la respiration est aisée. C'est la raison pour laquelle les constructeurs d' appareils respirateurs proposent aujourd ' hui des appareils avec des sections de tube de plus en plus fortes. It is obvious that the larger the section of the tube, the easier the breathing. This is the reason why the manufacturers of respirators today offer devices with increasingly large tube sections.
Cependant, au-delà de 4 cm2 de section intérieure, il devient difficile de chasser l'eau, l'effet capillaire se produisant avec de faibles sections n'ayant plus lieu, ce qui permet à l'air de traverser la masse d'eau sans 1 ' entraîner à l'extérieur du tube, et le nageur avale de l'eau quand il reprend sa respiration.However, beyond 4 cm2 of internal section, it becomes difficult to expel the water, the capillary effect occurring with small sections no longer taking place, which allows air to pass through the mass of water without dragging it outside the tube, and the swimmer swallows water when he takes a breath.
Or, pour une respiration confortable et non fatigante, il est souhaitable que la section interne du tube soit supérieure à 4 ou 5 cm2. Certains fabricants ont essayé de contourner le problème à l'aide de clapets ou de soupapes simples ou multiples montés sur des conduits dérivés, mais les résultats obtenus à ce jour ne sont pas satisfaisants et le prix du matériel devient prohibitif. However, for comfortable and non-tiring breathing, it is desirable that the internal section of the tube is greater than 4 or 5 cm2. Some manufacturers have tried to circumvent the problem using valves or single or multiple valves mounted on branch pipes, but the results obtained to date are not satisfactory and the price of the material becomes prohibitive.
Le dispositif suivant la présente invention supprime tous ces inconvénients. En effet, il permet de concilier une respiration aisée et une expulsion totale de l'eau hors du respirateur, et ceci pour un coût de fabrication extrêmement raisonnable. The device according to the present invention eliminates all these drawbacks. Indeed, it makes it possible to reconcile easy breathing and a total expulsion of water out of the respirator, and this for an extremely reasonable manufacturing cost.
Il est constitué de plusieurs conduits de faible section, mis en parallèle et raccordés à un embout buccal classique un que, de manière à obtenir une section de passage totale importante tout en permettant de chasser l'air grace à l'effet de capillarité des conduits empêchant l'air de traverser l'eau contenue dans ceux-ci. It consists of several ducts of small section, placed in parallel and connected to a conventional mouthpiece one that, so as to obtain a large total passage section while allowing to expel air thanks to the capillarity effect of the ducts preventing air from passing through the water contained in them.
Sur les dessins annexés, donnés à titre d'exemple non limitatif, d'une des formes de réalisation de l'objet de l'invention
La figure 1 représente le dispositif dans son ensemble, vu en perspective,
La figure 2 est une coupe transversale agrandie, suivant les flèches A-A de la figure 1,
Les figures 3 et 4 montrent dans les mêmes conditions des variantes de disposition des conduits.In the accompanying drawings, given by way of nonlimiting example, of one of the embodiments of the subject of the invention
FIG. 1 represents the device as a whole, seen in perspective,
FIG. 2 is an enlarged cross-section, along the arrows AA of FIG. 1,
Figures 3 and 4 show in the same conditions of the alternative arrangement of the conduits.
Le dispositif, figure 1 à 4, est constitué d'un embout buccal classique 1 relié par un raccord coudé 2 à un ensemble de deux à cinq conduits 3, 4, 5 solidaires et parallèles, de longueur égale à celle des appareils respirateurs courants. The device, Figure 1 to 4, consists of a conventional mouthpiece 1 connected by a bent connector 2 to a set of two to five conduits 3, 4, 5 integral and parallel, of length equal to that of current breathing apparatus.
La section de chacun des conduits est inférieure à 2, 5 cm2 et leur nombre est tel que la section totale de passage soit comprise entre 4 et 6 cm2. Ces conduits peuvent être réalisés soit en juxtaposant plusieurs tubes 7, 8 (figure 4) maintenus ensemble par une ou plusieurs bagues 9 ou par tout autre moyen,
soit avec un seul tube avec cloisons internes 6 (figures 2 et
3).The section of each of the conduits is less than 2.5 cm2 and their number is such that the total passage section is between 4 and 6 cm2. These conduits can be produced either by juxtaposing several tubes 7, 8 (FIG. 4) held together by one or more rings 9 or by any other means,
either with a single tube with internal partitions 6 (Figures 2 and
3).
Les conduits sont de préférence réalisés en matière
plastique, par soufflage, extrusion ou autre, mais peuvent égale
ment être métalliques, en aluminium, par exemple.The conduits are preferably made of material
plastic, by blowing, extrusion or other, but may equal
ment be metallic, aluminum, for example.
Grâce à sa simplicité et à son faible coût de revient, le dispositif qui vient d'être décrit se prête particulièrement bien à la réalisation d ' appareils respirateurs destinés à remplacer les actuels appareils monotubes ou à clapets. Thanks to its simplicity and low cost, the device which has just been described lends itself particularly well to the production of respirators intended to replace the current monotube or valve devices.
Le positionnement des divers éléments constitutifs donnent à ce dispositif un maximum d'effets utiles qui n'avaient pas été obtenus à ce jour par des dispositifs similaires. The positioning of the various constituent elements gives this device a maximum of useful effects which had not been obtained to date by similar devices.
