Abstract

L'invention porte sur un ensemble d'élément d'arrêt d'évacuation pour ouvrir et fermer de façon sélective une évacuation située à l'intérieur d'un bassin, d'une baignoire ou d'un évier. Un ensemble de bâti de levage est situé à l'intérieur du corps d'évacuation supportant un élément d'arrêt. Le bâti de levage comporte des première et deuxième régions annulaires couplées de façon sélective à un piston amené à s'étendre à l'intérieur du corps d'évacuation et à se retirer de celui-ci. Dans une première orientation, le piston s'étend à l'intérieur d'une première région annulaire, permettant à l'élément d'arrêt et au bâti de levage d'être amovibles du corps d'évacuation, tandis que, dans une deuxième orientation, le piston s'étend à l'intérieur d'une deuxième région annulaire, ce qui empêche l'élément d'arrêt et le bras de levage d'être retirés du corps d'évacuation.
