A blind made up of a plurality of customisable rigid slats enables the blind to be fitted snugly within any window opening or doorway as a result of the locking adjustability of the width of such slats. The slats each include a pair of elongate slat panels movable relative to one another between retracted and extended conditions, such that the operative width of the blind is greater in the extended condition than in the retracted condition. The blind further includes one or more fasteners, located at or near each of a pair of minor ends of the slat panels, for releasably fixing the pair of slat panels to one another in the retracted condition, the extended condition and/or any condition there between, thereby to operatively restrict relative movement between the slat panels in such condition.

Example room partitions are disclosed. An example room partition includes a plurality of poles to be suspended from a track. A curtain assembly has a plurality of sleeves through which the plurality of poles extends. The curtain assembly has a lowermost edge. An upper lock pin is attached to an upper end of a first pole of the plurality of poles and is movable between a raised lock position and a lowered unlock position relative to the first pole, the upper lock pin to be restrained when the upper lock pin is in the raised lock position, the upper lock pin to be unrestrained when the upper lock pin is in the lowered unlock position. A lower lock pin is attached to a lower end of the first pole and is movable between a descended lock position and an elevated unlock position relative to the first pole. The lower lock pin is to extend lower than the lowermost edge of the curtain assembly when the lower lock pin is in the descended lock position. The lower lock pin is to be above the lowermost edge of the curtain assembly when the lower lock pin is in the elevated unlock position.

A self-powered dynamic photovoltaic sunshade system having sunshades constructed of lightweight ETFE panels covered with at least one thin film of photovoltaic cells. The sunshades track the sun by light detectors, and move against the sun from east to west to block direct rays. The ETFE fabric is stretched on a lightweight frame, which rotates vertically around its axis as a pivotal panel for maximum solar protection. Sunshades rotate to face the sun by day, and reset to a starting position at night. Each sunshade is rotated by a stepped electric motor, powered by thin film(s) of solar photovoltaic cells. Sunshades are suspended between an electric motor shaft and a lower hinge. The sunshades are designed to provide sustainable dynamic shading for building facades exposed to different sun angles, are self-powered, and can generate electric power for other building functions, such as lighting and fan ventilation inside a building.

A wand assembly for use with an architectural-structure covering is disclosed. The wand assembly may include a first operating element (e.g., an operating cord) for moving the covering between extended and retracted positions and a second operating element (e.g., a tilt wand) for adjusting rotation of the covering between open and closed configurations. The first and second operating elements are coupled to a handle assembly via separate and distinct coupling mechanisms so that manipulation of the second operating element does not affect the first operating element thereby preventing twisting of the first operating element about the second operating element. The wand assembly may include a first, inner rotatable wand and a second, stationary outer wand. The inner wand is rotatable relative to the outer wand so that rotation of the inner wand does not rotate the outer wand, and hence the first operating element coupled to the outer wand.

A window curtain may include a top track, at least a sliding unit, and a plurality of shades, and the top track has at least two track rods sleeved together, which reduces the packaging and shipping costs. Each of the track rods is hollow to form a channel therein, and the channel comprises two vertical guide tracks. The sliding unit comprises a plurality of first sliding bases formed in parallel, and each of the first sliding bases other than the innermost one is connected to a second sliding base. Each of the second sliding bases comprises a pulley support, and each of the pulley supports has at least a pulley set installed thereon. The pulley sets are adapted to slide along the track rods through the guide tracks which have no height difference so as to improve the smoothness of sliding movement of the pulley sets.

An acoustic absorption and concealing device including at least one vertical strip including at least three structural layers, a central layer made of an acoustic absorbent material, and two external layers made of a knitted transonic material, applied on either side of the central layer, where the two external layers are made from flame-retardant polyester fibre threads and the central layer is made from polyester. The acoustic absorption and concealing device makes it possible to obtain a blind, or a partition panel of reduced thickness less than 7 mm having a low reaction to fire and optimal features of acoustic absorption, concealing and thermal reflections.

An anti-ballistic protection system for protecting a space in a building or vehicle comprising a protective barrier including one or more sheets of a laminated material having a plurality of layers of lightweight, flexible, ballistic resistant material such as woven sheets which are secured together using a glue, heat weld, or stitching. The system may include an automated control system operably configured to cause a change in state of the barrier from a retracted state to a protective deployed state, which may include a sensing system operably configured to detect a threatening event, wherein the sensing system upon sensing the threatening event triggers the barrier to transition from the retracted state to the deployed protective state such that in the protective state, the barriers are adapted to be resistant to penetration by high-speed ballistic objects such as bullets.

A motor driven system for raising and lowering a window covering executes motor ramp trajectory speed control. The motor ramp trajectory limits acceleration of an external motor from the idle (stationary) state to full operating speed, and limits deceleration of the motor from full operating speed back to the idle state. This function reduces stresses on a continuous cord loop drive mechanism. A control system manages solar heating effects in response to sunlight entrance conditions such as system sensor outputs, external weather forecasts, and other data sources. The system automatically opens or close the window covering to increase or decrease admitted sunlight under appropriate conditions. The input interface of the control system includes a visual display and input axis, which are aligned vertically if the window covering mechanism raises and lowers the window covering, and are aligned horizontally if the window covering mechanism laterally opens and closes the window covering.
