Abstract
(EN)
An apparatus includes a cylindrical housing having a hinge, a flapper attached to the hinge, and a slidable element is within the cylindrical housing, wherein the flapper can rotate from a first flapper position to a second flapper position. The slidable element is slidable from a first slidable position to a second slidable position and engages with the flapper at the first slidable position to prevent the flapper from moving to the second flapper position. The flapper is movable to the second flapper position when the slidable element is disengaged from the flapper. The apparatus also includes a latching mechanism attached to the slidable element movable from a first latching mechanism position to a second latching mechanism position. The slidable element is at the first slidable position when the latching mechanism is at the first latching mechanism position and at the second slidable position when the latching mechanism is at the second latching mechanism position.

La présente invention concerne un appareil comprenant un boîtier cylindrique doté d'une charnière, un battant fixé à la charnière et un élément coulissant situé à l'intérieur du boîtier cylindrique, le battant pouvant pivoter entre une première position de battant et une seconde position de battant. L'élément coulissant peut coulisser entre une première position de coulissement et une seconde position de coulissement et vient en prise avec le battant au niveau de la première position de coulissement pour empêcher le battant de se déplacer vers la seconde position de battant. Le battant est mobile vers la seconde position de battant lorsque l'élément coulissant est désolidarisé du battant. L'appareil comprend également un mécanisme de verrouillage fixé à l'élément coulissant mobile entre une première position de mécanisme de verrouillage et une seconde position de mécanisme de verrouillage. L'élément coulissant se trouve dans la première position de coulissement lorsque le mécanisme de verrouillage se trouve dans la première position de mécanisme de verrouillage et dans la seconde position de coulissement lorsque le mécanisme de verrouillage se trouve dans la seconde position de mécanisme de verrouillage.
