A window shade includes a reel and an aperture control module respectively assembled with a head frame, and a panel assembly including transversal vanes respectively connected with two panels. The reel is rotatable to wind and unwind the panel assembly. The aperture control module includes a positioning arm connected with a rubbing roller, and is operable to rotate the rubbing roller relative to the positioning arm and to displace the positioning arm and the rubbing roller between two positions, the rubbing roller being displaced away from a sidewall of the head frame in a first position and pressing the panel assembly against the sidewall in a second position, the rubbing roller being further rotatable relative to the positioning arm in the second position to cause relative sliding between the two panels for switching the panel assembly from a closed state blocking light passage to an open state allowing light passage.

A connection system for connecting at least one membrane to a rigid support, the connection system comprising: at least one elongated clamping profile, at least one locking unit configured for attaching the at least one elongated clamping profile to the rigid support, thereby clamping a portion of the at least one membrane between the at least one elongated clamping profile and the rigid support so as to achieve a sealing between the at least one membrane and the rigid support, wherein the at least one locking unit is a discrete state locking unit movable between several predetermined locking unit states, each locking unit state corresponding to a connection system stage, the predetermined locking unit states including: an Open locking unit state in which the locking unit is configured to provide a gap between the elongated clamping profile and the rigid support, allowing the portion of the at least one membrane to be inserted between the elongated clamping profile and the rigid support, the Open locking unit state corresponding to an Open stage of the connection system, a Closed locking unit state in which the locking unit is configured to press the clamping profile toward the rigid support so that the at least one membrane is clamped between the elongated clamping profile and the rigid support, the Closed locking unit state corresponding to a Closed stage of the connection system in which a sealing is provided between the at least one membrane and the rigid support, and an Intermediate locking unit state between the Open locking unit state and the Closed locking unit state, in which Intermediate state the at least one membrane is allowed to slide along the elongated clamping profile without disengaging therefrom, corresponding to an Adjustment stage of the connection system.

A magnetic track assembly including an elongate channel having an open side, an end wall, and two parallel side walls; a first magnet disposed within the elongate channel near an interior side of the end wall; a compartment defined within the elongate channel spaced from the first magnet; and a screen receiver disposed within the compartment and including a second magnet arranged facing the first magnet. In the magnetic track assembly, the first and second magnets are of opposite polarity and the screen receiver is loosely disposed within the compartment such that a magnetic bond is intact between the first and second magnets when the first and second magnets are close together and the magnetic bond is broken when the first and second magnets are pulled apart.

A customizable storm protection system for protection and aesthetics comprises a first jamb, a second jamb, a header, and a sill, each with a glazing recess, and each with a receptacle for inserting a screw boss that runs a length of each of the first jamb, the second jamb, the header, and the sill, wherein joined define a frame for the opening in a building. A customizable storm protection system may further comprise glazing received by the glazing recess of each of the first jamb, the second jamb, the header, and the sill. A customizable storm protection system may further comprise a storm track configured to the frame to, wherein the storm track identifies fastener locations for the screw boss within the frame, and wherein the storm track comprises a cap, a stanchion, and an attachment layer for attachment to the frame. The system enables different openings in a building to be individually customized for different types of storm protection while maintaining a uniform exterior appearance.

Provided is a water stopping tape having excellent workability.

The water stopping tape includes a substrate layer, a pressure-sensitive adhesive layer that is located on the substrate layer, and a swelling layer that is located on the substrate layer together with the pressure-sensitive adhesive layer and has at least one kind of deformation assisting structure selected from the group consisting of a groove and a cut.

A retractable, coilable, security barrier screen easily mounted around a door, window or other building opening such as a hallway entrance. The barrier is designed to withstand considerable forces from blunt force strikes, bullets and edged weapon slashing. As such, it has a strengthened spool tube, novel security barrier attachment methods, and redundant operational features such as dual (top and bottom spool locks), quad spool locking pins and a dual attachment for the fabric security barrier to the screen lock strip that includes both gluing and plate riveting.

This disclosure provides connectors for smart windows. A smart window may incorporate an optically switchable pane. In one aspect, a window unit includes an insulated glass unit including an optically switchable pane. A wire assembly may be attached to the edge of the insulated glass unit and may include wires in electrical communication with electrodes of the optically switchable pane. A floating connector may be attached to a distal end of the wire assembly. The floating connector may include a flange and a nose, with two holes in the flange for affixing the floating connector to a first frame. The nose may include a terminal face that present two exposed contacts of opposite polarity. Pre-wired spacers improve fabrication efficiency and seal integrity of insulated glass units. Electrical connection systems include those embedded in the secondary seal of the insulated glass unit.
