Abstract

La présente invention concerne des mécanismes avantageux de couvre-fenêtre, des systèmes et un appareil qui permettent d'actionner de multiples stores (p. ex. une paire de stores de fenêtres) ou jalousies à partir d'un seul rail de retenue. Les mécanismes de couvre-fenêtre permettent d'actionner le multiples stores par un seul mécanisme de commande, p. ex. un seul cordon d'actionnement. Un mécanisme de translation de mouvement est généralement mis en oeuvre pour actionner les multiples stores. Le mécanisme peut comprendre des enroulements à orientation opposée d'un premier et d'un second cordons de levage relativement à un élément rotatif. Les systèmes de l'invention peuvent être utilisés avec des stores (tels que des stores vénitiens) et des jalousies, si bien que l'interaction avec un cordon unique ou autre mécanisme de commande fonctionne pour replacer simultanément le premier et le second panneaux des stores ou des jalousies. Le premier et le second panneaux des stores ou des jalousies peuvent être choisis de façon avantageuse pour fournir divers degrés de blocage de la lumière et/ou des propriétés de protection de la vie privée.
