More Information
Summary:An operating system for a retractable covering for an architectural opening having at least a movable bottom rail and possibly a movable middle rail connected to a shade material includes control or guide cords extending from a head-rail for the covering to the bottom rail and extending through the middle rail. Manually operable locks are provided on the bottom rail and the middle rail to grip the cords as they extend therethrough and a take-up system is provided in the bottom rail that is biased so as to retain the cords in a taut condition during movement of the bottom rail or the middle rail. The bottom and middle rails are moved manually simply by manually releasing the manual locks provided thereon so that exposed control cords are alleviated.
