Abstract

La présente demande de brevet d'invention concerne un équipement ayant pour vocation de permettre le sauvetage de passagers prisonniers dans des cabines d'ascenseurs, de manière entièrement automatisée. Lors de la survenue d'une panne, qu'elle soit électrique, mécanique, électronique, hydraulique, électromécanique, etc., provoquant l'enfermement des passagers dans la cabine, le présent équipement entre en action. Un passager actionne un bouton (2) installé sur le panneau de l'ascenseur (E), notamment sur le tableau de commande (5) du système de sauvetage ; un signal électrique est envoyé à la salle des machines, de sorte que le contacteur 1 (C1) s'éteint, le tableau de commande (4) général de l'ascenseur n'étant alors plus du tout alimenté en énergie. Lorsque le contacteur 1 (C1) est éteint, le contacteur 3 (C3) s'éteint simultanément, évitant tout type de communication électrique entre le tableau de commande et le moteur (M1) de l'ascenseur et ses composants respectifs, tels que : capteurs, frein, codeur, entre autres.
