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 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.

The present invention provides a device to control the tilt angle of window blinds. The tilt device can be easily fitted to existing window blind systems. The device is also capable of working with existing home automation control systems. In a primary mode, the device can be controlled by receiving commands from a home or business automation controller using a wireless mesh network protocol. Examples of the wireless mesh network protocol may include, but are not limited to, Bluetooth MESH, Radio Frequency (RF) control, Z-Wave, ZigBee, Thread, FabFi, SolarMesh, WING, Wireless Backhaul (WiBACK) and so forth. Another approach can be by using drone from a remote position. In another approach, the window blinds may be controlled based on direct connection to another device that is part of the mesh network. In further approach, the window blinds may be controlled based on time. In yet another approach, the tilt position of the window blinds may be controlled based on the manual input device (rotary switch) connected to the device. The device may also control the window blinds at a site using a proximity detection of a mobile device or the network device, which may be based upon the detection of a plurality of zones. Each of the zones may be associated with a predefined temperature threshold of a thermostat including in the device or other energy consuming device where the temperature threshold corresponding to a zone may be different from the temperature thresholds corresponding with each of the other zones.

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.

The automatic window blind system provides gear driven window blind control. A solar power with back up battery provides energy to operate the window blinds and a light emitting diode strip that changes light colors depending upon daylight and night conditions. A plurality of toothed rack drives is driven by and drives rack gears in ensuring a positive operation of window blind hooks in pivoting window blinds that snap into the window blind hooks. A printed wiring board assembly controls functions and is accompanied by a rack sensor that cooperates with an optical sensor. The optical sensor and the rack sensor automatically position window blinds based upon light intensity.

A multi-partition blind system include a system of mechanisms that cause slats on a covering for an architectural opening to be partitioned into multiple operational sections. Partitions may be created to the extent of controlling each individual slat. Various embodiments and mechanisms are used to control, stabilize, and cause the opening and closing movement of one group of partitioned slats independent of others or individual slats independent of others.

A vertical blind (10) includes a plurality of strip-shaped vertically arranged shading elements (14, 15) which are held in pivot hooks (18) pivotable about a vertical axis. Two shading elements (14, 15) are arranged in each case on mutually remote longitudinal sides of a strip-shaped intermediate element (16) and together with the latter form a blind element (12). Easy assembly and disassembly of the shading elements (12) can be achieved by the fact that multiple blind elements (12) are provided separated from one another. Shading elements (14, 15) adjacent to one another are held by a common swivel hook (18). The swivel hook (18) has a receiving device (21) for the two adjacent shading elements (14, 15).

A modulator for a vertical louvre blind includes a case, a top cap, a transmission member, and a connector. The case has an encircling wall, a first axial hole, a bottom wall, and an accommodating space. The transmission member is accommodated in the accommodating space. An end of the transmission member is connected to the connector. The top cap is detachably disposed at the top side of the case, and has a base and a lateral plate formed at one side of the base. The lateral plate is formed with a horizontally extending section on the periphery of the base and further extends downwardly to be formed with a downwardly extending section. The horizontally extending section and the downwardly extending section collectively form a positionally limiting area to positionally limit the encircling wall, making the top cap strengthen the structure of the encircling wall of the case.
