Vertical blind assembly

摘要

A vertical blind assembly module includes a head rail unit with opposite sides and a unit axis extending between the sides, a housing and an axle pivotally connecting the housing to the head rail unit so that the housing can pivot about a pivot axis that is perpendicular to the unit axis. A slat is coiled in the housing so enabling the slat to be extended from the housing a selected distance and retracted into the housing. A foot rail unit is pivotally connected to the projecting end of the slat, the pivotal connection being collinear to the pivot axis. By turning the axle relative to the head rail unit about the pivot axis when the slat is extended, the slat can be turned between a closed position wherein the slat is parallel to the unit axis and an open position wherein the slat is perpendicular to the unit axis.

1. A vertical blind assembly comprising a module including:
a head rail unit having opposite sides and a unit axis extending between said sides; a housing coupled to the head rail unit, the housing pivoting about a pivot axis that is perpendicular to the unit axis; a venetian accordion blind having a first end coupled to the housing and a second end being coupled to a foot rail unit, the venetian accordion blind expanding and retracting to a selected distance, and the foot rail unit having opposite sides and a pivotal connection to said second end of the venetian accordion blind, said pivotal connection being collinear to said pivot axis, and a turning mechanism for turning the venetian accordion blind so that when the venetian accordion blind is extended said selected distance, the venetian accordion blind can be turned between a closed position wherein a surface of the venetian accordion blind is substantially parallel to at least the unit axis of the head rail unit, and an open position wherein the surface of the venetian accordion blind is substantially perpendicular to at least the unit axis of the head rail unit.
