A light blocking system is disclosed, which is adapted to be used in a vertical blind which includes a headrail, a control mechanism provided in the headrail, and a covering assembly including a plurality of slats. Each of the slats is connected to the control mechanism with an end thereof, and therefore is hung below the headrail. A gap is left between the covering assembly and the headrail. The control mechanism is adapted to turn the slats in situ relative to the headrail, or to move the slats back and forth in a longitudinal direction of the headrail. The light blocking system includes a cover plate provided corresponding to the gap, wherein the cover plate covers the gap when the covering assembly is in a closed state.

A covering for an architectural opening has a dual cord operating system. The covering may include a head rail, blind panels depending from the head rail, and an operating system. The operating system may include a housing connected to the head rail, a first drive assembly rotatably mounted within the housing and operable to move the blind panels between an extended configuration and a retracted configuration, and a second drive assembly rotatably mounted within the housing and operable to move the blind panels between a closed configuration and an open configuration.

A single-track stacking panel covering for an architectural opening has a headrail for mounting the covering above and in front of the opening, such as a window or door. The headrail has a single track. Suspended from the headrail and translatable therealong are panels oriented at a small angle relative to the headrail. When the covering is open, the panels form an overlappingly stacked array at one end of the headrail.

A multistate resistance adjusting device for a non-pull cord window blind includes a base, an adjusting unit, and an elastic member. The base has a bottom trough provided on the periphery thereof with positioning grooves. The adjusting unit has a control pin provided with a transmission portion rotatable and vertically movable on the base and a positioning portion provided on the outer peripheral surface of the transmission portion and connected with an adjusting rod. When the positioning portion is engaged with one of the positioning grooves, the control pin is disabled from rotating relative to the base and adjusting the resistance applied on the lift transmission cord. When the control pin is moved upwardly to separate the positioning portion thereof from the positioning groove, the control pin is rotatable relative to the base, and the resistance applied on the lift transmission cord is adjustable through the adjusting rod.

The present invention provides a device to control the tilt angle of window blinds. The device is capable of working with existing home automation control systems. The device is configured to operate in one or more modes such as, a primary mode and a secondary mode. In the primary mode of operation of the device is controlled by the home automation controller using a wireless mesh network protocol or a home automation protocol. In the secondary mode, the device 604 is operate independent of the mesh network in a standalone manner.

THIS invention relates to a slat for a blind and a blind formed from such slats. More specifically, the invention relates to a customisable rigid slat, or blind made up of a plurality of such customisable rigid slats, that 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 slat includes a pair of elongate slat panels movable relative to one another between retracted and extended conditions, such that the operatively width of the slat is greater in the extended condition than in the retracted condition. The slat 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.

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 window covering system is described herein. The system includes one or more motorized window coverings, and includes both local and cloud based control facilitated by motors or actuators in each window covering that are actuated by a controller. Each window covering further includes a processor with settings stored in memory that direct the controller. Sensors send both local and remote sensor data along with real time weather data to the processor. The processor uses this sensor data to update charts and schedules in memory, then sends commands to the controller based on these updated charts and schedules according to user defined and factory set parameters. Additionally, the window coverings each have a network device and wireless transmitters enabling connection via a mesh network, the network controlled by one or more mobile devices which receive user input.

A window blind control system includes a control device, having a housing; a motor connected to one or more gears positioned within the housing; a hollow drive shaft coupled to the one or more gears, the hollow drive shaft to receive a window blind tilt rod; a control system having a communication board associated with a home automation wireless mesh protocol to communicate with one or more networked devices; a home automation system including the one or more networked devices; an interface accessible from a computing device and to communicate with the home automation system and the control device, the interface is to receive commands from a user.
