Abstract

La présente invention a trait à un store autorelevable ainsi qu'à un mécanisme de commande du store. Le store comprend, en particulier, une unité d'entraînement telle qu'un ressort à force constante, qui est adapté pour appliquer une force de rotation sensiblement constante sur l'axe d'entraînement. Un cordon d'enroulement est monté de manière coaxiale sur l'axe d'entraînement et comprend au moins un tambour d'enroulement relié de façon fonctionnelle à une deuxième extrémité du cordon élévateur et doté d'une partie resserrée, ainsi qu'un élément de positionnement rotatif destiné à déplacer le cordon d'enroulement le long de l'axe d'entraînement, durant la rotation de l'élément de positionnement. Le cordon d'enroulement est adapté de manière à transformer la force de rotation de l'axe d'entraînement en une force de relevage sur le cordon de relevage, la force de relevage étant plus importante que la force de descente exercée par l'élément store et le rail inférieur tout au long du processus d'ouverture et de fermeture. Un élément d'embrayage ou élément de verrouillage est également relié à l'axe en mode opérationnel, et adapté de manière à verrouiller, de façon libérable, l'axe d'entraînement dans la position désirée.
