Title (EN) DEVICE FOR A SNORKEL TUBE AND SNORKEL TUBE INCORPORATING SAID DEVICE
(FR) DISPOSITIF DESTINÉ À UN COL D'ENTRÉE D'AIR ET COL D'ENTRÉE D'AIR INCORPORANT LEDIT DISPOSITIF
Abstract:
(EN) The invention relates to a device for closing the free end of a snorkel tube or an adaptor tube that is or can be attached to said snorkel, said free end having an opening for allowing air into the snorkel, the device comprising a first movable member (503) associated with a seal member (504), the device further comprising a second movable (205) member that is designed to be attached to the tube or an element integral therewith, said second movable member being made of, or associated with, a material having a higher density than water such that, when it is submerged, it will receive a buoyant force lower than its weight, said second movable member being displaceable from a position of non-interference to a position of interference, and vice versa, with said first movable member, and said displacement being such that, when the opening of the tube is submerged or tends to be submerged, the first movable member is in a position of interference with said second movable member and is pushed to the closed position by the buoyant force exerted on said first member and/or by the force exerted by the abutment of at least part of the second member against said first member due to a component of the weight force exerted on said second member in the direction of movement of said second member toward said first member.
(FR) La présente invention concerne un dispositif permettant de fermer l'extrémité libre d'un col d'entrée d'air ou d'un tube d'adaptateur qui est ou peut être attaché audit col d'entrée d'air, ladite extrémité libre ayant une ouverture permettant de faire entrer l'air dans le col d'entrée d'air. Le dispositif comprend un premier élément mobile (503) associé à un élément joint (504). Le dispositif comprend également un second élément mobile (205), conçu pour être fixé au tube ou à un élément qui y est intégré, ledit second élément mobile étant constitué d'un matériau ou associé à celui-ci, ayant une densité supérieure à celle de l'eau, de sorte que, lorsqu'il est immergé, il reçoive une poussée d'Archimède inférieure à son poids, ledit second élément mobile pouvant être déplacé d'une position de non interférence à une position d'interférence et vice versa. Ledit premier élément mobile et ledit déplacement sont tels que, lorsque l'ouverture du tube est immergée ou tend à être immergée, le premier élément mobile se trouve dans une position d'interférence avec ledit second élément mobile et poussé vers la position fermée par la poussée d'Archimède exercée sur ledit premier élément et/ou par la force exercée par la butée d'au moins une partie du second élément contre ledit premier élément, en raison d'un composant de la force de pesanteur exercée sur ledit second élément dans la direction de déplacement dudit second élément vers ledit premier élément.
