A method of using an anti-ballistic protection system for protecting an interior space in a building. The ballistic barrier includes a laminated material having a plurality of layers of lightweight, flexible, ballistic resistant material such as woven sheets which are secured together into the laminate using a adhesive, heat weld, or stitching. The ballistic barrier is configured to be in a compact retracted state which can be deployed to provide a protective state to protect against kinetic ballistic projectiles. The system may include an automated control system operably configured to change the state of the ballistic barrier from the retracted state to the protective deployed state, such that upon sensing a threatening event or condition triggers a transition from the retracted state to the deployed protective state such that in the protective state. The ballistic barrier in the deployed state is configured to be resistant to penetration by high-speed ballistic projectiles such as a bullet fired from a gun or a shrapnel from a bomb to protect the interior space.

A window blind includes a headrail, two lift cords, a blind body, a bottom rail, and two cord winding assemblies that are respectively installed on two opposite sides of the long axis of the bottom rail. The other ends of the lift cords are respectively tied to respective adjustment columns of the cord winding assemblies. When the window blind is folded or stretched, unfortunately, when the winding stroke is inconsistent, the blind body is not folded uniformly or skewed, and the adjustment column of the cord winding assembly on one side can be finely adjusted, so that one of the lift cords is gradually wound and covered on the adjustment column, and indirectly drives the bottom rail and the blind body to gradually adjust to substantially parallel to the bottom of the headrail, thereby effectively achieving the effect of fine-tuning and correcting the blind body.

A ladder tape device for a venetian blind includes a U-shaped fixing base fixed in a head rail of the venetian blind, a ladder tape retainer with opposite ends placed on corresponding two side-panels of the fixing base, a plurality of ladder tapes with a top end of each ladder tape passing through the fixing base and being wound on the ladder tape retainer, and a limiting cover buckled on the top end of the fixing base, an inner wall of the limiting cover and an outer wall of the top end of the ladder tape retainer are separated by a predetermined distance to form a ladder tape limiting space.

A hem length adjusting device for a window blind without exposed pull cord includes a base, a first worm shaft disposed in the base, and a second worm shaft disposed in the base. The base is mounted in a bottom rail and has a first hole for penetration of a lifting hole. The first worm shaft has a driving hole exposed out of the bottom side of the bottom rail for engagement with a hand tool. The second worm shaft is meshed with the first worm shaft so as to driven by the first worm shaft to rotate for winding the bottom end of the lift cord. By this way, because the top end of the lift cord is kept still, the bottom rail is raised when the lift cord is wound around the second worm shaft, thereby adjusting the height above the ground of the bottom rail.

A modular shade includes at least one module that consists of a head rail unit, a foot rail unit, at least one intermediate rail unit, and a plurality of slat components. A top slat may be coupled to the head rail unit and the intermediate rail unit, and a bottom slat component may be coupled to the intermediate rail unit and the foot rail unit. Further, additional intermediate rail units and intermediate slat components may be added to the module to alter the shape and size of the module, and the module may be coupled to one or more additional modules to change the overall shape and size of the modular shade.

The present disclosure describes roll-up coverings of custom length and/or width for architectural openings, and a method of assembling the same. The custom covering includes at least one outer elongate tape, at least one inner elongate tape, and a plurality of slats. The tapes preferably have lengths along central longitudinal axis extending between first ends and second ends of the tapes that are selected to correspond to the custom length of the covering. The slats are preferably transverse to, spaced apart along, and coupled to the tapes at any desired location along the tape lengths to achieve desired spacings of the slats, thereby providing a subassembly of custom length. The slats may have lengths extending between first ends and second ends of the slats, orthogonal to the central axis of the tapes, and selected to provide a custom width of the subassembly.
