Abstract

L'invention concerne un tuyau d'aspiration de poussière télescopique pour aspirateur comprenant un tube interne et un tube externe, l'extrémité avant duquel comportant un manchon de positionnement recevant le tube interne. Dans la paroi interne du manchon de positionnement sont ménagées des rainures de guidage dotées d'une aiguille de positionnement. Une protubérance part du manchon de positionnement et sert à recouvrir la partie saillante comportant une rainure coulissante sur laquelle se trouve une coche servant à libérer et contenir l'aiguille de positionnement. La rainure coulissante comporte un élément coulissant dont les deux extrémités présentent respectivement un ressort, la partie inférieure de l'élément coulissant présentant deux rainures inclinées en forme de M, entre lesquelles est plaquée une pièce exerçant une pression sur l'aiguille de positionnement. A l'extérieur du tube externe est placé un élément de traction déplaçant l'élément coulissant. L'avantage des deux rainures inclinées en forme de M sur l'élément coulissant est qu'elles permettent le déplacement bidirectionnel de l'élément de traction, ce qui permet de simplifier la structure du tube d'aspiration de poussière. De plus, l'invention est avantageuse en termes d'économie de matière à utiliser pour la fabrication de l'aspirateur, d'où une réduction des coûts.
