A covering for an architectural opening includes a head rail, a bottom rail with a take-up roller therein and an intermediate rail with both the intermediate rail and bottom rail suspended from the head rail, a fabric material interconnecting the intermediate rail with the bottom rail and being adapted to be wrapped around the roller in the bottom rail, said fabric including a pair of vertically oriented sheets that are horizontally spaced by a plurality of vertically spaced horizontal vanes with the vanes being movable between open and closed positions by opposite vertical movement of the sheets of material. A first control system is provided for raising and lowering the bottom rail and a second control system for raising and lowering the intermediate rail as well as tilting the intermediate rail to effect an opening or closing of the vanes.

L'invention concerne une couverture pour une ouverture architecturale qui comprend une traverse de sommet, une traverse inférieure munie d'un rouleau d'appel du tissu et d'une traverse intermédiaire. La traverse intermédiaire et la traverse inférieure sont toutes deux suspendues à partir de la traverse de sommet, une matière en tissu interreliant la traverse intermédiaire à la traverse inférieure et étant conçu pour être enroulé autour du rouleau dans la traverse inférieure. Ledit tissu comprend une paire de voiles orientés verticalement qui sont horizontalement espacés par une pluralité de volets horizontaux espacés verticalement, lesquels sont amovibles entre une position ouverte et une position fermée par un mouvement vertical opposé des voiles de matière. On prévoit un premier système de commande pour relever ou descendre la traverse inférieure et un second système de commande pour relever ou descendre la traverse intermédiaire ainsi que pour incliner la traverse intermédiaire afin d'assurer l'ouverture ou la fermeture des volets.
