A base structure and associated method for converting the base structure into an operable vane on a shade for an architectural opening. The base structure includes a back sheet and a front sheet attached together in engagement regions spaced along the length of the back sheet and front sheet. The front sheet is separated into front strip sections having a free end. Operating elements are positioned along the back sheet and situated so as to move relative thereto. The operating elements are attached adjacent to a free end of the front strip. Movement of the operating elements actuates the free end of the front strip to move from a closed position to an open position as desired by the user.

A daylighting device according to one aspect of the present invention includes a daylighting member including a first substrate having light transparency and a plurality of daylighting units having light transparency which are provided on a first surface of the first substrate, in which the daylighting unit has a reflective surface which reflects light incident to the daylighting unit, the light which is reflected on the reflective surface and emitted from a second surface of the first substrate has characteristics that the light proceeds toward a space on the same side as the side where the light is incident to the reflective surface among two spaces divided with a virtual plane as a boundary which is vertical to the second surface of the first substrate and parallel to an extension direction of the daylighting unit, and the daylighting member exhibits light absorption characteristics for absorbing a part of the light incident to the plurality of daylighting units.

An actuation device for the slats of a wing of a shutter has two sections intended to be mounted in the uprights of a frame of the wing, a plurality of flanges that are rotatably mounted in holes obtained in the sections, and locking devices disposed in such a way to hold the flanges and prevent the flanges from coming out of the holes of the section.

A light blocking or blackout composite material is described. The light blocking material includes at least two metalized layers. In one embodiment, a polymer film is coated on both sides with a first metalized layer and a second metalized layer. The metalized layers may have matching or different optical densities. Other layers can be combined with the metalized layers in order to provide a finished surface and/or to protect the metalized layers.

A high efficiency daylight directing structure for application on fenestration deploys closely spaced macroscopic bars of transparent resin to eliminate different forms of glare. The spaced apart surfaces provide for efficient reflection of selective incident light, by TIR or metallic surfaces, via the ultra-smooth native surfaces from a mold or casting process. A close spacing is readily obtained in various attachment methods to boost efficiency. The fabrication method allows selective deposition of absorbing layers, such as by of painting/printing between alternating native optical surface to provide one way transparency at high angles of incidence. The bars are supported on at least one common planar surface by transparent support member with an optical quality adhesive material filling any imperfection in the bars common planar surface that form in fabrication.

A pleated shade assembly includes a shade having multiple pleated portions formed transversely formed on the front side thereof. Any two of the pleated portions adjacent to each other have an overlapped portion which is a combination of two respective longitudinal sides of the adjacent pleated portions. A restriction member is located at the rear side of the shade and connected between the top and the bottom of the shade. The restriction member restricts expansion of the pleated portions so as to prevent the pleated portions from being overly deformed.

A window shade includes a top box, a bottom bar and a shade connected between the top box and the bottom bar. Multiple wire units extend through holes of the shade. Each wire unit includes two connection wires and multiple cross wires which are spaced and transversely connected between the connection wires. Each wire unit has an operation wire for controlling the shade, the operation wire alternatively extends between the cross wires along the longitudinal direction of the shade. The holes in the shade each include two passages formed at two inner ends thereof. The connection wires extend through the two passages. At least one tooth extends from each of two insides of each of the holes and located between the two passages. When the wire unit is pulled outward, the cross wires are restricted by the teeth so that the operation wire is restricted from being pull out.
