The present disclosure relates to device for controlling window blinds, more particularly the present disclosure relates to an automatically calibrated device for controlling new or existing horizontal window blinds.
Window blinds are used in homes to control inlet of sunlight to homes. A conventional window blind system includes a headrail that is fixed at top of the window. Further, the window blind system includes a blind assembly suspended from the head rail. The angle of the blinds can be controlled by application of an external force in order to tilt the window blinds that changes the amount of sunlight entering the home through the window.
Various types of mechanisms are available to lift or change the tilt angle of the window blinds. Some window blind systems may have a visible lift cord and tilt cord to change the tilt angles of the window blinds. In such window blind systems, lift and tilt cords may be provided, suspended on right and left hand sides of the head rail that needs to be pulled or rotated to lift and change angles of the window blinds. Since, the lift cord and tilt cords are visible, it is accessible to children and can be pulled or stretched by them, while playing that may cause an accident.
There are other window blinds systems wherein, the tilt cord or lift cords are hidden and are not easily accessible or are concealed. In some window blind systems having concealed cords, there is provided a spring means to keep the blinds in balance and to hold the blinds and bottom rail in position after an adjustment of the blinds. There are other window blind systems known in the market, with concealed cords, which uses a tension force of a positioning cord in order support the bottom rail in positon after an adjustment of the window blinds. However, the use of spring is always prone to elastic fatigue. After some time of usage, when the elastic fatigue kicks in, the spring mechanism or the positioning cord system cannot support the bottom rail accurately in position. Also, majority of these designs are used for controlling the elevation of the blinds only. For controlling the tilt angle of the blinds, additional tilting rod and mechanism must be added to the already complex window blind system. Since, the lifting and tilting angle of the blinds is separately controlled.
There are also automatic systems that are available in the market to control the opening and tilt angle of the window blinds. However, such systems need to be separately integrated with control systems like new wiring, network etc. Also, it requires an additional controller system to be installed. This means that there is an extra controller installed within a home to control blinds in case it already has some home automation system pre-installed.
Unfortunately, when it comes to controlling horizontal blinds no product is on the market that directly operates with existing home automation systems using a wireless mesh network protocol. End users are required to use hand held RF remote, a custom smart phone application or custom tablet application to control their window blinds. This limitation forces users to have multiple interfaces to control automation devices in the home. To solve this problem for window blinds we invented the motorized device for controlling horizontal window blinds tilt. The device's unique feature is the ability to integrate and work with home automation wireless mesh protocols without the need to add a costly network connection bridge between the window blind controlling device and the home automation network. This unique feature allows the end user to control their window blinds and many of their home automation devices with a single interface. This unique feature also allows the motorized device to interact with other home automation devices such as network connected sensors.
Therefore, there exists a need for an improved window blind control system to efficiently control the blinds.
The present invention comprises a device for controlling tilt angle of window blinds having one or more of the features recited in the appended claims and/or one or more of the following features, which alone or in any combination may comprise patentable subject matter:
Accordingly, in an embodiment of the invention, there is provided a device for controlling tilt angle of window blinds. The device includes a housing unit, wherein the housing unit is retrofittable, that means, that the housing can be fitted into any type of existing headrail of the window blinds system.

The devices 102A-102N, the device 104, the home automation controller 106 may communicate with each other via a wireless mesh protocol. Examples of the wireless mesh network protocol may include, but are not limited to, Bluetooth MESH, Radio Frequency (RF) control, Z-Wave, ZigBee, FabFi, SolarMesh, WING, Wireless Backhaul (WiBACK) and so forth. Wireless mesh control network has been explored for working of this invention as it has many intrinsic advantages. One of the main advantages of such a network is that the devices to be controlled need not be placed near the home automation controller. The device to be controlled can be accessed by relaying control signals from other network devices connected to the same home automation controller.
Further, the device 104 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 104, the control device 1042 is controlled by the home automation controller 106 using a wireless mesh network protocol or a home automation protocol. The secondary operational mode allows the device 104 to be operated in manual mode using a manual rotary switch that will be discussed later in detail.
In another mode of operation, the device 104 may control the window blinds 108 based on change in temperature in the environment surrounding the device 104 or the window blinds 108. In further mode of operation, the window blinds 108 may be controlled by the device 104 based on time. For example, the control device 1042 may open or close the window blinds 108 based on the time of a day or night. For example, the control device 1042 may close the window blinds 108 at 3 PM. In some embodiments, the time related information may be entered by a user to a user interface provided on the home automation controller 106.
In yet another mode of operation, the device 104 or the control device 1042 may control the opening and closing of the window blinds 108 based on a position of the network devices 102A-102N such as a mobile phone of the user, a smart watch, a laptop, and so forth. For example, the network sensors 110A-110N interfacing the device 104 may sense when the network device 102A-102N approaches the device 104 or is within a predefined area nearby the network sensors 110A-110N interfacing the device 104, and the opening and closing of the window blinds 108 may be controlled accordingly. The control device 1042 may also control the window blinds 108 at a site using a proximity detection of a mobile device or the network device 102A-102N, which may be based upon the detection of a number of zones. Each of the zones may be associated with a predefined temperature threshold of a thermostat or the control device 1042 included in the device 104 or other energy consuming device. Further, the temperature threshold corresponding to a zone may be different from the temperature thresholds corresponding with each of the other zones. A database of the home automation controller 106 may store multiple values such as, a position threshold, a plurality of temperature thresholds, a plurality of time values, a plurality of voice commands. The user may control the window blinds 108 by giving voice commands. The device 104 may be configured to receive the voice commands from the home automation controller 106 and process them based on comparison of pre-stored voice commands for controlling the opening and closing of the window blinds 108.
In another mode of operation, the device 104 may control the window blinds 108 based on a sunrise a sunset schedule. This mode of operation can be coupled by providing interfacing of the device 104 with a plurality of network connected photo-sensors. The photo-sensors sense the absence or presence of sunlight using the photoelectric receiver. The device 104 may be configured to receive the network connected photo-electric receiver commands from the home automation controller 106 and process them based on the pre-stored instructions for controlling the opening and closing of the window blinds 108.
In an embodiment of the invention, the device 104 may be interfaced with network sensors 110A-110N such as, a temperature sensor for sensing temperature of a site or zone.
In another embodiment, the device 104 is a member of network, allowing it to communicate with other devices on the same network by using a centralized controller.
In yet another embodiment, the device 104 associates with another specific device, allowing the specific device to communicate directly without the need for the centralized controller. This association of the device 104 with the specific device is a direct association or assigned association. The direct association is the simplest form of associating Z-Wave or mesh devices where a source node (when the housing unit set to “association set mode”) receive the identity code of a target node (another device) and get associated together. The assigned associations allow the housing unit to connect with another network or mesh network devices that are not “in range” with the help of a controller with knowledge of the complete network and its routes.
Further, associating the source node (the housing unit) with the target node (another device in mesh network) directly, enables them to send signals directly without involving the central controller. This saves time, reduces the complexity of the communication and the amount of airtime taken. It also allows sensors to be used in networks without a static controller.
In yet another embodiment of the invention, there may be an input device connected to the device 104 like a remote control or a manual rotary switch. Through this remote control or the manual rotary switch, a user can control the device 104 for tilting of the window blinds.

Furthermore, at step 806, it is determined whether the command is received or not. If the command is not received, the device 200 sleeps for a time-period and wakes again listens for any command sent to it. However, if the command is received by the device 200, the position of the window blinds are adjusted at step 808. At step 810, upon completion of positioning the window blinds, the device 200 will transmit a broadcast status message to the wireless mesh network indicating its position and return to sleep before waking up to listen for new command.

Then at step 906, it is checked whether the determined distance is less than or equal to the distance threshold value. If the distance is less or equal to distance threshold, that has been input by the user into the network sensors 110A-110N through the user interface, then step 908 is executed else step 902 is executed. Thereafter, at step 908, the control device 1042 may control a tilt position of the window blinds 306A-306N after receiving the tilt command from the network sensor 110A-110N.
Now referring to
At step 1002, the temperature sensor may sense a temperature in an area near or around and inform the home automation controller 106. In some embodiments, the temperature sensor may sense the temperature of the site or zone. Then, at step 1004, the home automation controller 106 may compare the sensed temperature with a predefined temperature threshold stored in a database of the home automation controller 106. In some embodiments, the home automation controller may include a thermostat for sensing the temperature in a zone or area. At step 1006, it is checked whether the sensed temperature is equal to or more than the temperature threshold. When the temperature is less than the temperature threshold, then the control goes back to step 1002, else step 1008 is executed. At step 1008, the tilt position of the window blinds such as the window blinds 306A-306N are controlled as per the predefined instructions stored in database of the home automation controller 106. The predefined instructions may be like closing window blinds when the temperature exceeds the predefined temperature threshold i.e. 40 degree Celsius, and opening the window blinds at temperature 25 degree Celsius.

At step 1102, the network connected photo-sensor may sense the sunlight in an area near or around the device 104 at regular intervals. In some embodiments, the photo-sensor may sense the sunlight of the site or zone. Then, at step 1104, the home automation controller 1064 may compare the sensed sunlight with a predefined sunlight threshold stored in a database. In some embodiments, the home automation controller 106 may include a thermostat for sensing the sunlight in a zone or area. At step 1106, it is checked whether the sensed sunlight is equal to or more than the sunlight threshold. When the sunlight is less than the sunlight threshold, then the control goes back to step 1102, else step 1108 is executed. At step 1108, the tilt position of the window blinds such as the window blinds 306A-306N are controlled as per the predefined instructions stored in the home automation controller 106.
The control device 1042 may tilt the window blinds to following positions based on value slider position or percentage value received: Open tilted up, Open titled fully (horizontal), Open tilted down, closed tilted up, closed tilted down, and so forth. In a specific embodiment, the window blinds can be tilted to an angle of any value falling between 0 and 99 percent wherein 0 percent signifies closed down, 50 percent signifies full open and 99 percent signifies closed while tilted up.
The control device 1042 may can send the blinds position or Open/Closed status to other devices such as the home appliances connected to a home automation mesh network.
