Abstract

L'invention porte sur un mécanisme élévateur du type à tirage, qui comprend un élément de fixation (100, 1), un mécanisme autobloquant (200) et un cordon de tirage (300). Le mécanisme autobloquant (300) comprend des blocs en coin supérieur et inférieur (220, 210) qui peuvent monter et descendre et qui sont agencés dans l'élément de fixation (100, 1). Les blocs en coin supérieur et inférieur (220, 210) peuvent s'accoupler l'un à l'autre et se déplacer l'un en sens inverse de l'autre sans s'écarter. Une extrémité du cordon de tirage (300) est reliée à la partie supérieure du bloc en coin supérieur (220) et l'autre extrémité est reliée à la partie inférieure du bloc en coin inférieur (210). Sous l'effet du poids du mécanisme autobloquant, les blocs en coin supérieur et inférieur se rapprochent longitudinalement l'un de l'autre et s'élargissent transversalement vers l'extérieur pour résister contre la paroi intérieure de l'élément de fixation, de manière à réaliser l'auto-blocage. Sous l'effet de la force de traction du cordon de tirage, les blocs en coin supérieur et inférieur sont écartés longitudinalement l'un de l'autre de manière à réaliser l'auto-blocage et, de cette façon, on peut régler la hauteur d'une pomme de douche en tirant le cordon de tirage vers le haut et vers le bas.
