The invention relates generally to systems and methods for controlling systems with moving parts. In particular, the invention relates to systems and methods for controlling, for example by remote activation, an actuating mechanism of a blind system to open or close blinds of that blind system.
In accordance with the present invention, systems and methods for controlling blinds are described. These systems and methods may be carried out using a remote device (e.g., a remote control, a computer, a mobile phone, etc.). The system and methods may provide for an outer housing (e.g., a tube) having an inner cavity sized to include various components. Such components may include: a motor having a motor shaft configured to rotate about a first axis; a programmable circuit; a power source configured to power the motor; and a magnetic clutch. Any of these components are optional.
The outer housing may couple to a head rail or any part of blinds such as a gear box or an attachment attached to a gear box. The attachment may receive a motor or a motor may be substituted for a motor that couples to the gear box. A shaft of the motor may be controlled to rotate a certain distance based on a rotational counter or a predetermined time period, and the time period of rotation may be control by a user activating one or more buttons on a remote control. Rotation of the shaft may tilt open or close blinds. The motor may be disengaged by a user so that the user may manually open and close blinds.
The outer housing may connect to a tilt mechanism using any one of various means, including male and female connectors and cavities configured to receive tilt mechanisms. The outer housing may connect to a gear box. Such a connection may utilize a cavity in the outer housing from receiving a shaft from the gear box, or a shaft formed with the outer housing that is received by a cavity formed with the gear box.
A motor may be formed inside a gear box, and a control device may connect to the gear box to deliver power and/or control instructions to the motor. A spring may be used to disengage a gear from the motor and to engage that gear with another gear so that a user may manually tilt open and close blinds without the operating the motor. The spring may be replaced by a mechanical or electrical device such as but not limited to a solenoid, or a simple mechanical male and female tongue and a lip that would lock to each other.
The present application may be more fully appreciated in connection with the following detailed description taken in conjunction with the accompanying drawings.
Various aspects of the invention are described below. It should be apparent that the teachings herein may be embodied in a wide variety of forms and that any specific structure, function, or both, being disclosed herein is merely representative. Based on the teachings herein one skilled in the art should appreciate that any aspect disclosed may be implemented independently of any other aspects and that two or more of these aspects may be combined in various ways.
Aspects of the invention may feature mechanical, electric and/or other systems for controlling the position of blinds commonly used in windows and doors. It is to be understood, however, that the inventive aspects described herein and understood by those skilled in the art can be applied to all types of blinds and other systems with moving parts.
The present invention offers various advantages over previous systems and methods for controlling blind systems. For example, one aim of the present invention relates to ease of installation and use. As one of skill in the art will come to understand, the inventive aspects of the present invention permit a user to install various implementations of the invention without having to dismantle or substantially modify the blind system. In accordance with several embodiments, a user need only attach that embodiment's inventive blind control device to existing actuators of typical blind systems. Attachment may require only having to slide an embodiment's inventive blind control device over a hook or other feature, or into a cavity without any need of cutting or otherwise modifying the blind control device. Users of the various inventive blind control devices will benefit greatly by avoiding the significant investment of time (e.g., in relation to user installation) and/or money (e.g., in relation to professional installation) required to install previous blind control devices. Certain inventive blind control devices are also significantly smaller than previous blind control devices, and can be attached to a blind system to appear as if the respective blind control device was part of that blind system.
Further benefit is created by the power delivery aspects of various embodiments. For example, use of batteries as opposed to hardwiring to electrical conduits behind a wall, permit a user to quickly install those embodiments without any need to hire an electrician. Furthermore, the batteries are easily accessible, and can be changed by removing a cap. The ease of removing the batteries is contrasted to other systems that require a trained personal to remove and reinstall the blind in order to replace the batteries, or to hardwire a power source. The ease of battery removal reduces the cost of maintenance significantly and allows an operator to continually use the remote option without abandoning it due to maintenance cost.
Various embodiments described herein permit a user to easily program and control that embodiment's blind control device using wireless data/signal transmission or by activating physical components (e.g., a manual switch, push button, etc.) on the blind control device. For example, programming and control may occur at/from a wireless device (e.g., a mobile computing device, a computer or router capable of transmitting wireless signals, a remote control device). Signals/data may be received from and/or sent to those wireless devices using RF, IR, Bluetooth, or other wireless technologies. The present invention contemplates appropriate software (e.g., applications for displaying a user interface, software for controlling a motor or other drive mechanism of certain blind control devices) and hardware (e.g., processors, sensors, switches, etc.) at the wireless devices and the blind control devices to carry out and manage the programming and control functionality described herein.
One of skill in the art will appreciate various control commands, including commands for rotating a motor axle (described in more detail below) in one direction to open blinds a desired amount and rotating the motor axle in the other direction to close the blinds a desired amount. For example, when a user presses any of various buttons on a wireless device, a signal may be sent to a processing unit of the blind control device, which in turn controls the rotation of the motor shaft to open or close the blinds. Pressing one button/switch and releasing it may result in the blinds opening or closing to a predetermined position (e.g., opening to let in the most light or closing to block the most light). Pressing another button and releasing it may result in the blinds opening or closing only for the period of time in which the button was push. Under this scenario, a user would have to press and hold the button until the blinds have opened or closed a desired amount. Pressing another button may control any number of blind systems and subsets of blind systems. Pressing yet another button may indicate a predefined operation (e.g., the opening or closing of the blinds at a later time or under certain conditions). One of skill in the art will appreciate that user-activated buttons can be replaced by a computer interface where a user selects presently-desired or scheduled operations.
One of skill in the art will further appreciate various programming commands using the same buttons/switches and/or user interfaces.
Programming and control of certain inventive blind control devices may alternatively involve sensors and/or processing components that receive input relating to light, sound, motion, position of blinds, temperature, time or other properties/characteristics, and then use received input to control a blind system. Such sensors and/or processing components would be positioned within and/or on an external surface of a respective blind control device.
In accordance with one example, a blind control device may include or use information from a sensor to determine when sensed ambient light (e.g., sunlight) exceeds a threshold brightness level (e.g., a brightness level determined by a user-programmable or preset value), and may then control a blind system to open or close its blinds. By way of another example, a blind control device may include a sensor that determines if sensed ambient temperature exceeds or falls below a threshold temperature level (e.g., a temperature level determined by a user-programmable or preset value), and may then control a blind system to open or close its blinds based on the determination. A blind control device may also or alternatively respond to sound (e.g., a human voice, including the user-programmable or preset words “open” and “close”) or to motion (e.g., a human entering a room).
A blind control device may also or alternatively control a blind system to open or close its blinds based on the time of day (e.g., as determined by an internal time-keeping component, or as determined by a signal received from an external device such as a clock, remote control with clock, etc.). Or, the blind control device may control a blind system to open or close its blinds based on a predefined time period since an event as determined by an internal or external time-keeping component or device (e.g., since the blinds opened or closed, since a sensed amount of light exceeded a threshold level of light, etc.).
One of skill in the art will appreciate that the sensor information regarding temperature, light, motion and sound, and the timer information may be obtained by the blind control device from remote sensors and timers not physically attached to the blind control device. Receipt of such sensor and timer information may be obtained using various wireless signal transmission techniques described herein in relation to remote wireless devices.
For a better understanding of certain aspects and features of the present invention, attention is drawn to the following Overview.
While the details of the embodiments of the invention may vary and still be within the scope of the claimed invention, one of skill in the art will appreciate that the figures described herein are not intended to suggest any limitation as to the scope of use or functionality of the inventive aspects. Neither should the figures and there description be interpreted as having any dependency or requirement relating to any one or combination of components illustrated in those figures.
Aspects and features of the invention are designed to operate in relation to mechanical and/or electrical systems with movable components. In accordance with various embodiments described herein, aspects and features of the invention are designed to manipulate one or more vertical and horizontal louvers/slats (generally referred to herein as “blinds”) of a blind system by transferring rotational motion from a motor to an actuator mechanism of the blind system that opens and closes the blind louvers/slats. Such actuator mechanisms may include, without limitation, tilt mechanisms (e.g., with a wand or baton attached thereto), ropes, chains and other components of blind systems that open and close blind louvers/slats.
It will be understood that the terms “blind” or “louver” or “slat” may refer to individual vertical or horizontal members of blind systems which are capable of being opened, closed or otherwise adjusted. The term “tilt mechanism” may refer to an actuating mechanism that enables the opening, closing or other adjustments to the blinds. It will be understood that ‘blind system” is described herein as a single blind system. However, the teachings herein may apply to control of several blind systems, each with a blind control device, and each controlled by the same remote control device.

In an alternative configuration shown in
One of skill in the art will appreciate that a friction clutch could be used by replacing the magnets with a suitable material. One of skill in the art will appreciate alternative embodiments that do not use a magnetic or frictional clutch, where that motor 130 could connect directly or through other components to the blind connector component 110. In accordance with some of these alternative embodiments, a fractional number of rotations of the blind connector component 110 (or the motor shaft 631 described below) may be tracked. Based on the fractional count of rotations, the blind control device could, using preprogrammed information, determine the position of the blinds in relation to a fully-closed position and a fully-open position. Based on a determined position, the blind control device could stop rotation of the blinds when they reach the fully-closed and fully-open position. Although other clutch systems can be used, the magnetic clutch embodiment is preferred due to cost and ease of operation.
Adhesive, friction, mere insertion, a mechanical fastener, or another method of attachment may be used to hold the motor connector component 125 in place around the motor shaft 631. When the motor shaft 631 rotates upon delivery of electrical current via power leads 632, the rotational energy may be transferred to the blind connector component 110 through the motor connector component 125 and the magnets 120a-b, which operate as a magnetic clutch as previously described. Power leads 632 operate to deliver power the motor 130 from batteries 155 via the circuit board 145 of
One of skill in the art will appreciate that the motor 130 may operate to control an actuator of a blind system without the magnetic clutch. For example, the motor shaft 631 could directly attach to the actuator of the blind system or to some intermediate component between the actuator and the motor shaft 631 (e.g., connector 1810).
One of skill in the art will appreciate that the motor 130 may operate with a rotational count mechanism (not shown) that counts a number of rotations of the motor. Such a rotational count mechanism may be integral with or connected to the motor or circuit board 145. By knowing the number of rotations of the motor shaft 631, the motor shaft can be instructed not to over-rotate the actuator of a blind system, thereby preventing damage to the blind system or blind control device, and also reducing unnecessary power use of the batteries 155. Knowing the number of rotations will permit the blind control device or a remote control device to track start and stop positions of the motor shaft for further control of the motor shaft and additional precision in relation to the operation of the blind control device.
When the motor 130 is inserted into the motor housing 135, the power leads 632a-b may extend into and/or beyond the locking section 638. Upon insertion of the motor 130 into the motor housing 135, the leads 632a-b may reside on opposite sides or the same side of an inserted pin 140. The leads 632a-b are configured to connect to respective power terminals 847a-b of the circuit board 145 shown in
As previously mentioned,
The functionality of the control interface 146 may include programming of functional instructions, transmitting/receiving of signals/data to/from other components (e.g., sensors, motors, wireless devices, processing components that carry out instructions stored in memory, etc.), and controlling of the motor shaft 631. Accordingly, the control interface 146 may include an interface for programming and controlling the operation of the blind control device 100, including the motor shaft 631. The control interface 146 may further include an interface for sending and receiving signals. Signals received by the control interface 146 may indicate different types of information, including a direction or position of the motor shaft 631, a fractional number of times the motor shaft 631 has rotated in one or more directions, a position of the blinds (e.g., in relation to a minimum and maximum rotation position), a sensed temperature level, a sensed light amount, or a sensed motion.
The control interface 146 may comprise a push switch that, when pushed, will pair the device 100 with a remote control, or with one or more buttons on the remote control. The remote control may then instruct the circuit board 145 (e.g., one or more processing and control components thereon) to control the operation of the motor 130 to open or close blinds of a blind system. One of skill in the art will appreciate that such a push switch may be replaced by a signal transceiver and a signal processor that operate to receive a wireless signal and process it in accordance with the methods described herein to control the motor 130.
Although not shown, the circuit 145 may include a processor operable to process information described herein (e.g., sensor information, user instructions, etc.). That processing component may execute instructions stored in memory to control the operation of the motor based on the information.

As shown by the combination of
As shown in
The batteries 155 may be removed after the second battery connector 160 is disengaged from the outer housing 105. Removal of the batteries 155 may be carried out without any need to remove the blind control device 100 from the blind system to which it is coupled. The ease of removing batteries in this fashion is yet another advantage of certain aspects of the present invention over previous blind control systems.
The batteries 155 may be of any type in relation to size, shape and voltage. The batteries 155 may also be rechargeable. Although not shown, a solar charger may be connected to or integral with the device 100 to recharge the batteries 155. Such a charger could wrap around or otherwise attach to the outer housing 105, or could be adapted to removably connect to the device 100 and the batteries 155 for the purpose of charging the batteries 155.
Attention is now turned to
The anti-rotation feature 115 and adaptor 1680 operate to prevent the outer housing 105 and any component securely attached to it (e.g., the motor housing 135 via pin 140 or other attachment technique described herein) from rotating when the motor shaft 631 rotates. The anti-rotation feature 115 and adaptor 1680 ensure that the rotational motion from the motor shaft 631 is not transferred to the outer housing 105, and is instead transferred through the motor connector component 125, through the magnetic clutch (e.g., magnets 120a-b), through the blind connector component 110, and to the actuating mechanism of a blind system. During rotation initiated by the motor shaft 631 and before the blinds are fully closed or open, the force applied by the tongue component 115 when it is inserted into the adaptor 1680 does not break the magnetic or frictional bond of the magnets 120a-b, thereby ensuring that the rotational motion of the motor shaft 631 is transferred by the magnetic clutch (e.g., magnets 120a-b) to other components for rotating an actuating mechanism of a blind system.

The adapters in
One of skill in the art will appreciate different designs of the feature 115 and the adaptor 1680 that are within the spirit and scope of the invention. For example, the feature 115 and/or adaptor 1680 may be formed on or attached to the blind system or the blind control device 100 in any manner consistent with the disclosure herein.
The remote control device 1899 is preferably digital, but may also be analog. The remote control may include a timer that tracks time and causes the motor 130 to operate based on the tracked time. For example, the timer may cause the motor 130 to cause blinds to open in the morning and close at night. The digital version of the remote control device may include control buttons 1802 for programming the operation of one or more blind control devices 100. Such programming may specify times of operation, degrees to which blinds are opened, and other operations. Also, such programming may be stored locally at the blind control device 100 or on the remote control device.
The control buttons may also include forward and reverse buttons 1803 and 1806 for control the operation of the blind control device 100 and control to direction of rotation for the motor 130. The control buttons may also include a round (or any shape) button 1804 that may select particular blind control devices 100 that will receive particular programming instructions. Selected blind control device 100 may be indicated by number or other designation on the display 1801.
The control buttons may also include group buttons 1807 (e.g., three group buttons 1-3) that allow a user to select various blinds to operate at the same time (eg, blinds 1, 4 and 8). Each button may be programmed for particular groups, and when activated will control only that group. Having group control eliminates the need for individually selecting each blind control device 100 to execute a particular operation.
