Vertical retractable blind

摘要

A vertical retractable blind is constructed to include a fixed headrail, a lifting rail vertically movable in horizontal below the headrail, two positioning cords adapted to support the lifting rail at the desired elevation. The positioning cords each have a first end connected to the headrail and a second end respectively extended across the lifting rail and fixedly secured to a respective fixed point outside the lifting rail to provide a tension force to the lifting rail. A retractable blind body is connected between the headrail and the lifting rail and vertically extended out/received subject to vertical movement of the lifting rail.
