A cord winding assembly for a window shade includes a housing, a first and a second spool portion respectively connected with a first and a second suspension cord, and a transmission axle. The first and second spool portions are disposed in a cavity of the housing. The transmission axle is rotationally coupled to the first and second spool portions and extends outside the housing at least at one end thereof, the transmission axle and the first and second spool portions being rotatable concurrently relative to the housing in a first direction for respectively winding the first and second suspension cords around the first and second spool portions, and in a second direction opposite to the first direction for respectively unwinding the first and second suspension cords from the first and second spool portions.

A motorized window treatment may provide a low-cost solution for controlling the amount of daylight entering a space through a window. The window treatment may include a covering material (e.g., a cellular shade fabric or a roller shade fabric), a drive assembly for raising and lowering the covering material, and a motor drive unit including a motor configured to drive the drive assembly to raise and lower the covering material. The motorized window treatment may comprise one or more battery packs configured to receive batteries for powering the motor drive unit. The batteries may be located out of view of a user of the motorized window treatment (e.g., in a headrail or in a battery compartment). The motorized window treatment may use various power-saving methods to lengthen the lifetime of the batteries, e.g., to reduce the motor speed to conserve additional battery power and extend the lifetime of the batteries.

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.

A skew adjustment method and apparatus for adjusting the skewed condition of a movable rail of a window covering in which the movable rail is supported by lift cords wrapped around spools. A drive train disconnecting mechanism is used to disconnect a first spool from a second spool, the first spool is rotated relative to the second spool, thereby changing the length of the first lift cord relative to the second lift cord until the movable rail is in the desired position; and then the first and second spools are reconnected so the first and second spools rotate together. An end cap may be used to enable multiple disassemblies and reassemblies of the end cap to access the skew adjustment mechanism. In one embodiment, there are two movable rails, and the lift cords for both movable rails extend through the same rout holes in the covering. Disconnecting the first spool from the second spool may activate a mechanism that prevents the second spool from rotating.

A shade adapted for covering a classroom viewing window and assisting with compliance with emergency protocol during an emergency is disclosed. The shade may include a plurality folds connected to each other by a plurality of hinges configured to cover a classroom viewing window. Emergency related information and status indicators may be revealed upon the unfolding of the shade to assist teachers, school officials, police, and others to comply with established school emergency protocol. The shade further fulfills the requirement that the classroom viewing window be covered during an emergency lockdown. The shade may function as a standard “Exit” sign during non-emergency time. Another shade may include a case holding a material portion with handles that enable the shade to be moved up and down.

A battery-powered motorized window treatment for covering at least a portion of a window may be adjusted into a service position to allow for access to at least one battery that is powering the motorized window treatment. A headrail of the motorized window treatment may be adjusted to the service position to allow for easy replacement of the batteries without unmounting the headrail and without requiring tools. The motorized window treatment may comprise brackets having buttons that may be actuated to release the headrail from a locked position, such that the head rail may be rotated into the service position. The headrail easily rotates through a controlled movement into the service position, such that a user only needs one free hand available to move the motorized window treatment into the service position and change the batteries.

A shading device including a first driving shaft that is rotatably supported within a headbox and may drive a first moving member and a second driving shaft that is rotatably supported within the headbox and may drive a second moving member, the shading device includes a first pulley that drives the first driving shaft, and a second pulley that is disposed at a position different from the first pulley in a longitudinal direction of the headbox and drives the second driving shaft.

A housing including a reflective mirror, a light source or a speaker, a processor, and a microphone, wherein the housing is configured to couple to a wall, wherein the processor is coupled to the light source or the speaker and the microphone, wherein the microphone is configured to receive a voice sound from a user positioned in an operational proximity to the reflective mirror and the microphone, wherein the processor is configured to process the voice sound from the microphone and control the light source or the speaker based on the voice sound.

The sunshade comprises a first edge strip and a second edge strip, at least two conductor wires extending from the first edge strip to the second edge strip and a movable protective curtain suspended from the conductor wires. The first edge strip and/or the second edge strip have a substantially rigid gripping projection for attachment to the edge profile of the glazing. The method comprises attaching the sunshade to a glazing element having a first edge profile and a second edge profile, wherein the edge profiles have a fastening groove in the longitudinal direction of the edge profile. The method comprises providing a substantially rigid gripping projection with a tip portion on the first edge strip, placing the first edge strip in a first position alongside the first edge profile, fitting the tip portion of the gripping projection of the first edge strip into the fastening groove of the first edge profile, and rotating the first edge strip about its longitudinal axis to a second position so that at least the tip portion of the gripping projection moves into the locking groove.

A window blind includes: a headrail; a blind body and a cord reel, both mounted on the bottom wall of the headrail; two lift cords each having one end fixedly provided at the cord reel and the opposite end inserted through the headrail and the blind body and then fixed to the lower end of the blind body; and a weight and a bottom rail, both provided at the lower end of the blind body. The weight and a slat of the blind body are mounted into the bottom rail through either of the lengthwise ends of the bottom rail and are thus received in the bottom rail, with the junction between the slat and the other slats exposed through a mounting aperture of the bottom rail. The bottom rail can be mounted as needed to enable stable expansion and retraction of the window blind.
