A method for manufacturing an operation device for shutters includes a step of forming a ladder a step of forming a receiving element, a cord accommodated in the receiving element, and a step of connecting multiple connecting elements to the ladder and the receiving element. The operation device for shutters includes a ladder, a receiving element accommodating a cord therein, and the connecting elements connected to the ladder and the receiving element.

A covering for an architectural feature having generally horizontal vane elements extending between generally inner and outer vertical support members that can adjust and control the amount and quality of light transmitted through the covering is described. In one embodiment, the covering has elongate tapes as vertical support members that have a width substantially less than the length of the vane elements, and adjacent inner and adjacent outer elongate tapes are separated by a distance. In one embodiment, the vane elements are multi-layered, cellular vanes. The elongated multilayered vanes may include elongate stiffeners that may be associated with, coupled to, and or inserted within pockets formed in, the multilayered vanes. Also disclosed is a method of operation and manufacture.

A skew adjustment mechanism is used for adjusting the length of a lift cord on a window covering. The lift cord extends from a lift spool at a first end to an anchor drum at a second end. A cord wrap post is provided between the lift spool and the anchor drum so that the lift cord can be wrapped around the cord wrap post to provide friction between the lift cord and the cord wrap post when the lift cord is taut in order to reduce the amount of holding force that is needed to prevent the anchor drum from rotating.

A covering for an architectural feature having generally horizontal vane elements coupled to and located between generally front and rear generally vertical support members, which in preferred embodiments are adjustable to control the amount of light transmitted through the covering. In one embodiment the covering has three dimensional multi-layered, cellular vanes, and in another embodiment, the one or more support members are formed of a dark color, the rear support member(s) may be formed of material that is darker than the front support member(s), or vise versa. In another embodiment, the support members, e.g., sheers, have an openness factor, preferably as low as about sixty-five percent (65%) to as large as about ninety percent (90%). Other embodiments include structure, assemblies and methods for controlling the closure of the covering as well as embodiments of bottom rail assemblies. Also provided is a method of manufacturing the covering.

A ladder cord fastening seat for a non-pull window blind includes two vertical posts located opposite to each other and an arc bridge. The ladder cord fastening seat is fastened in a top beam through the two vertical posts. Each of the vertical posts has a cord inserting hole for a ladder cord to be inserted therethrough. The arc bridge is used for fastening the ladder cord. The arc bridge connects the two vertical posts in such a way that an accommodation space is defined to accommodate a transmission member located in the top beam.
