A retractable cover for architectural openings having collapsible vanes includes a support structure in the form of a sheet of material, monofilaments, tapes, ribbons, cords, or the like, supporting an upper edge of a plurality of vertically spaced, horizontally extending vanes with the lower edges of the vanes in most embodiments of the invention being connected to operating elements adapted to raise the lower edges of each vane toward the upper edges to define openings or gaps between the vanes through which vision and light can pass in an open condition of the covering. Variations of the covering do not require movement of a lower edge of a vane relative to an upper edge but simply movement of some vanes relative to other vanes. The vanes can be made of materials having different flexibilities and where more rigid materials are used, creased fold lines can be established for desired operability.

The invention relates to an assembly of a tilt control cord (106) and a fastening element (1) for fastening to a slat (102A) of a window covering. The fastening element has an elongate body with a length corresponding to the width of the slat. The fastening element includes second fastening means for attaching the ends of the tilt control cord.

The invention also relates to a window covering having a cord spool (104), wherein the tilt control cord (106) is wrapped around the cord spool (104) and extends to the top slat (102A) on which the fastening element (1) is attached.

The invention also relates to a method of assembling the window covering.

A covering for an architectural opening that includes a plurality of flexible slat materials overlapped and joined along longitudinal edges resulting in a continuous roll-up covering material. The covering includes a first fabric material including an inner surface, an outer surface, a top end, and a bottom end, the bottom end of the first fabric material being folded over to define a first folded piece of fabric; a second fabric material including an inner surface, an outer surface, a top end and a bottom end; and a stiffener positioned between the first folded piece of fabric and the second fabric material along the top end of the second fabric material, an inner surface of the stiffener being adhered to the outer surface of the second fabric and an outer surface of the stiffener being adhered to the first folded piece of fabric.

In one aspect, a shade assembly may generally include a shade fabric having a front side and a back side. The shade assembly may also include two or more batten spacers, with each batten spacer being coupled to the shade fabric at spaced apart locations along a vertical length of the fabric. Moreover, the batten spacers may be substantially aligned with one another horizontally along the back side of the shade fabric. When the shade fabric is moved to an opened position, the batten spacers may be configured to vertically engage one another to form a vertical spacer stack along the back side of the shade fabric.

In one aspect, a cord retention assembly for a covering for an architectural structure may include a cord guide coupled to a shade panel of the covering that is configured to receive a corresponding cord of the covering. The cord guide may form a closed shape and may also be configured to define an entryway around at least a portion of a perimeter of the closed shape. In addition, the cord retention assembly may include at least one retention member installed relative to the cord guide such that the retention member(s) prevents the entryway of the cord guide from being rotated past the attachment location defined between the shade panel and the cord guide.
