Abstract

La présente invention concerne un siège de toilette de type à engrenage à crémaillère permettant de tirer automatiquement la chasse des toilettes au moyen de l'énergie du poids du corps. Selon l'invention, un engrenage de transmission de force d'entraînement installé sur un siège de toilette tourne au ralenti pour entrer en prise avec un engrenage à crémaillère, lorsque le poids d'un utilisateur amène le siège des toilettes à se déplacer vers la surface supérieure d'un corps principal, tandis qu'un ressort de siège est comprimé et qu'un galet à fil est amené à tourner par rotation de l'engrenage de transmission de force d'entraînement et tire vers le bas un fil de la chasse, de manière à ouvrir une soupape d'ouverture/de fermeture, lorsque l'utilisateur quitte le siège, et à permettre au siège des toilettes de se remettre en position d'origine au moyen de la force de récupération du ressort du siège. L'eau située à l'intérieur d'une chambre à pression à robinet de chasse peut ainsi être vidangée par la soupape d'ouverture/de fermeture ouverte, ce qui permet d'éliminer les excréments d'un corps principal des toilettes avec de l'eau acheminée par une conduite d'eau.
