Patent

CA 2581013

A blind includes a headrail, a bottomrail, a plurality of slats positioned between the headrail and the bottomrail, a plurality of ladders, a plurality of lift cords and a plurality of connectors. Each ladder is composed of two vertical portions and a plurality of rungs in parallel between the two vertical portions. The lift cords are positioned at two opposite sides of the slats and near the vertical portions of the ladders. Each slat has at least a hole near a longitudinal side edge, and a connector is deposited between the ladder and each slat. Then the connectors can combine the ladders and the lift cords with the slats in such a way that the slats can be kept from moving so as to shut off light effectively.

Un store comprend un rail supérieur, un rail inférieur, une pluralité de lames placées entre le rail supérieur et le rail inférieur, une pluralité d'échelles, une pluralité de cordons de tirage et une pluralité de connecteurs. Chaque échelle est composée de deux parties verticales et d'une pluralité d'échelons en parallèle entre les deux parties verticales. Les cordons de levage sont placés sur deux côtés opposés des lames et près des parties verticales des échelles. Chaque lame possède au moins un trou près d'un bord latéral longitudinal, et un connecteur est déposé entre l'échelle et chaque lame. Ensuite les connecteurs peuvent combiner les échelles et les cordons de levage avec les lames de telle sorte que les lames ne puissent pas se déplacer de manière à éteindre efficacement la lumière.
