This document pertains generally, but not by way of limitation, to fenestration hardware for one or more of securing and operating a fenestration assembly.
Fenestration assemblies include one or more of door and window assemblies that provide access. For example, fenestration assemblies include fenestration frames and fenestration panels. Fenestration panels, such as doors, sashes or the like, are usually (but not always) movably coupled with fenestration frames to provide access (e.g., entry and exit through the assembly, ventilation or the like).
Fenestration assemblies include latches and operation hardware that permit securing and opening or closing of the assemblies. For instance, latches secure fenestration panels in a closed position and minimize unauthorized opening of the assemblies (e.g., by intruders, inclement weather, children or the like). The latches are operable, for example with manual operators, to permit human manipulation of the latches to lock and unlock (secure and unsecure) the fenestration assemblies.
In other examples, fenestration assemblies include operation hardware to facilitate opening and closing of fenestration assemblies. For instance, balance systems, counterweights, casement mechanisms or the like are installed with fenestration assemblies, like windows, to assist with opening and closing. The operation hardware optionally supports some of the weight of the fenestration panel, and is used by a homeowner, worker or the like to conduct closing and opening movement of the fenestration assembly. In a casement or awning fenestration assembly having a rotatable window sash, the operation hardware supports the sash, promotes movement of the sash (when operated), and guides movement of the sash toward open or closed positions and intermediate positions therebetween.
Optionally, fenestration assemblies are offered with powered hardware that operate one or more of the latches or operation hardware. For instance, the powered hardware is attached to a fenestration assembly operation hardware, latch or the like to permit remote operation of the fenestration assembly. In some examples, the powered hardware is a distinct component with its own housing that is coupled to the fenestration assembly (e.g., over the fenestration frame). The powered hardware is configured to operate a latch, move the fenestration panel or the like.
The present inventors have recognized, among other things, that a problem to be solved includes maintaining the capability to conduct manual operation of fenestration assembly latches and operation hardware while at the same time providing powered control of the latches and operation hardware. For example, systems including powered hardware couple the hardware with the fenestration assembly latching, operation hardware or both to remotely control the fenestration assembly latching and operation (e.g., opening and closing). The powered hardware is installed, in some examples, in a manner that intimately connects the hardware with the window and makes manual operation of either or both of the latches or operation hardware difficult. For instance, powered actuators are coupled with one or more of the latches, operation hardware (e.g., mechanisms) or the like. The actuators include various mechanical and electrical components that, when not operated, interfere with manual operation of the latches and operation hardware because of their mechanism type, the desire for fenestration security or both. For instance, motors, mechanisms or the like coupled with latches and operation hardware resist outside forces. The motors or mechanisms move when powered, but otherwise maintain their present configuration (or resist movement from the present configuration) when unpowered. For instance, a closed and locked window remains locked and closed as specified when the powered hardware was last operated. Manual operation is, in many circumstances, unable to unlock or move the fenestration panel because of the powered hardware (e.g., to maintain security, because of the mechanism type or the like).
However, in some situations manual operation is specified and useful. For instance, in a power failure manual operation of the fenestration assembly latches and operation hardware is helpful to facilitate egress, ventilation, closure of the fenestration assembly or the like. In other situations, manual operation is desired to provide access through or closure of a fenestration assembly in an emergent situation where powered hardware is without power, the control interface (e.g., a smartphone, control pad or the like) is unavailable or the like. With inclement weather, closing and latching of a fenestration assembly may be specified and manual operation needed where the control interface is not available. Similarly, in a home or building fire rapid manual operation of the latches and operation hardware may be specified to facilitate egress from the home or building. In other examples, the powered hardware may fail and manual operation is helpful to continue access through the fenestration assembly until maintenance of the powered hardware is conducted.
In other examples, powered hardware is installed to a fenestration assembly in a manner that detracts from the appeal of the assembly. For instance, the powered hardware is installed over or along a portion of the frame and is readily visible, or interferes with the daylight opening of the fenestration assembly. In one example, the powered hardware has a distinct housing that is installed to the fenestration assembly and projects (at least partially) from the fenestration frame thereby disrupting the fenestration profile of the fenestration assembly. The interruption of the fenestration profile is another example of a problem recognized by the present inventors.
The present subject matter can help provide a solution to this problem, such as by providing one or more fenestration automated operation assemblies that conduct powered functions of the fenestration assemblies while at the same time permitting manual operation of the assemblies. The fenestration automated operating system in a first embodiment includes a panel operating assembly having a panel actuator (e.g., screw drive, cylinder and piston or the like) coupled with a power source, such as a motor. The panel actuator is coupled between the fenestration frame and the fenestration panel. Actuation of the panel actuator, for instance with remote controls, moves the fenestration panel between open, closed and intermediate positions. The panel operating assembly, for instance the power source and the panel actuator, are within the fenestration frame. For instance, the panel operating assembly fits within a fenestration profile of the fenestration assembly and does not interrupt the profile.
Additionally, the panel operating assembly includes a panel shoe that interconnects the panel actuator with one of the fenestration panel or the fenestration frame and permits manual operation of the fenestration assembly. The panel shoe includes anchored and movable configurations. In the anchored configuration the panel shoe is coupled with the fenestration panel and constrained to limited or no movement (e.g., is statically coupled). In the movable configuration the panel shoe is decoupled from the fenestration panel and movable relative to the panel. For example, the fenestration panel includes a shoe track having an anchor socket that receives a shoe anchor of the panel shoe. In the movable configuration the shoe anchor is decoupled from the anchor socket and the panel shoe may move freely along the shoe track. Accordingly, manual force applied to the fenestration panel readily moves the panel with minimal (e.g., no or decreased) resistance by the panel actuator. In another example, the anchor socket includes a manual tolerance slot that includes sufficient manual tolerance to permit limited movement of the fenestration panel in the anchored configuration (in comparison to the movable configuration). The manual tolerance allows a user to move the fenestration panel a limited amount, for instance to expose a release operator of the panel shoe that toggles the shoe anchor between the anchored and movable configurations. When exposed, the operator may toggle the shoe anchor to the movable configuration to readily permit further manual opening or closing movement of the fenestration panel.
The fenestration automated operating system in a second embodiment includes a panel latch assembly having a latch actuator (e.g., screw drive, cylinder and piston or the like) coupled with a power source, such as a source of motive power. The latch actuator is coupled with one or more latches of the fenestration assembly. In one example, the latch actuator is coupled with a tie bar coupled between a plurality of latches. Actuation of the latch actuator (e.g., with remote controls) moves the one or more latches between secure and unsecured positions. The panel latch assembly, for instance the power source and the latch actuator, are within the fenestration frame. For instance, the panel latch assembly fits within a fenestration profile of the fenestration assembly and does not interrupt the profile.
Additionally, the panel latch assembly includes a shuttle, such as a tie bar having latching and unlatching lugs spaced apart (a shuttle track), that interconnects the latch actuator with the one or more latches and permits manual operation of the latches. The shuttle includes a shuttle track with one or more engagement surfaces, such as the latching and unlatching lugs. At least one of the latch actuator (such as a drive lug of the latch actuator) or the latch are movably coupled relative to the shuttle track. Movement of the latch actuator is transmitted through the drive lug to the latch to accordingly move the latch between the secure and unsecured configurations.
With the latch in the secured position the drive lug of the latch actuator is, in one example, disengaged from the one or more engagement surfaces (e.g., lugs) of the shuttle track (e.g., the space between lugs along the tie bar). With the disengagement the tie bar and the latches are manually movable relative to the disengaged latch actuator. For instance, the drive lug of the latch actuator is back driven (e.g., a powered or actuated back drive) away from the lugs along the shuttle track after the latch is secured to disengage the drive lug from the one or more engagement surfaces (the latching or unlatching lugs). In an example, the back driving provides a shuttle track tolerance. The panel latch assembly includes a manual operator, such as a lever, handle or the like, coupled with the one or more latches. Because the latch actuator is spaced with the shuttle track tolerance the manual operator is freely permitted to operate the one or more latches (e.g., to move to the unsecured position) without resistance from the latch actuator.

As provided herein, in various examples, the operating assembly shell 112, the latch assembly shell 110 or the like are, in various examples, selectively removeable from the fenestration assembly 100 to provide access to, maintenance of, replacement or the like of one or more of the panel latching assembly, panel operator assembly or the like. Additionally, the operating assembly shell 112 and the latch assembly shell 110 minimize tampering with the assemblies and interior components of the fenestration assembly 100.
In other examples, the latch assembly shell 110, operating assembly shell 112 or the like are configured to conceal other components of the fenestration assembly 100 including, but not limited to, one or more of control modules such as the control module 206 shown in
As previously discussed, the fenestration assembly 100 includes a manual operator 108 operates one or more latching, panel movement or the like in a manual alternative manner to the one or more automatic panel latch assemblies. In one example, the manual operator 108 couples with one or more mechanisms associated with the panel latch assembly to permit manual operation of the panel latch assembly and accordingly manually latch and unlatch the fenestration assembly 100. Manual operation is provided to ensure latching and unlatching are available in the event of a power outage, emergent situation (including an emergency), absence of a control interface (e.g., a mobile device or panel) or the like. Manual operation of the panel latch assembly permits manual opening of the fenestration panel 104, for instance with a manual crank, hand pushing and pulling or the like.
As further shown in
In another example, the fenestration assembly 100 includes one or more window opening control devices 154. In one example, the window opening control devices 154 are coupled between the fenestration panel 104 and the fenestration frame 102 to prevent opening of the fenestration panel 104 beyond a specified distance or position (e.g., four inches or the like) relative to the fenestration frame 102. In various examples, the fenestration assembly 100 includes one or more window opening control devices 154 to accordingly provide redundancy along the fenestration assembly 100 to minimize accidental opening of the fenestration panel 104 beyond a specified distance.
In the example shown in
As shown in
In another example, the manual operator 108, such as a lever, handle or the like, is coupled with the tie bar 202 and the latches 200 to permit manual operation of the latches 200, for instance, in an emergent situation (also referred to as an emergency), power outage, while a control interface (such as a mobile device, remote device, wall mounted controls or the like) is not available or the like. As described herein, the manual operator 108 is, in one example, configured to freely operate relative to the remainder of the panel latch assembly 204 in an unpowered situation. As discussed herein, the panel latch assembly 204 permits manual operation (in addition to automated operation, also referred to as powered operation herein) through the use of one or more of a shuttle track 314, manual tolerance configuration 316 (shown in

In operation, the panel latch assembly 204 in an automated configuration moves the drive lug 304 and accordingly moves the tie bar 202 and latches 200 between latched and unlatched configurations. The latch configuration is shown in
Upon receipt of a latching instruction, for instance, to move the latches 200 toward the latched configuration relative to an unlatched configuration (corresponding to movement between
As shown in
In one example, where manual unlatching is specified, the manual operator 108 is raised relative to the configuration shown in
In an example where power returns, the emergent situation is over or the like, automated operation of the panel latch assembly 204 is readily permitted. For example, operation of the latch actuator 300 moves the drive lug 304 from the manual tolerance configuration 316 toward and into engagement with the latching lug 308, the unlatching lug 310 or the like. In various examples, the fenestration assembly 100, such as the control module 206, automatically moves the drive lug 304 to the manual tolerance configuration 316 after one or both of automated latching or unlatching to ensure the fenestration assembly 100 is readied for manual operation with the manual operator 108 at any time (e.g., when any power outage, emergent situation, or absence of a control interface or the like occurs).
In one example, the panel actuator 152 is operated in an automated fashion, for instance, by way of instructions or control provided by the control module 206. For instance, the panel actuator 152 communicates with the control module 206 with one or more of a wired or wireless connection. Upon receipt of instructions to move the panel actuator 152 and accordingly move the fenestration panel 104 between open and closed configurations including to an intermediate position therebetween, the control module 206 provides an instruction to the panel actuator 152 and the panel actuator operates to drive the fenestration panel 104 in one or more of the opening or closing directions. The panel shoe 404 includes a joint, such as a hinge joint 410, to permit articulation of the panel actuator 152 relative to the panel shoe 404, for instance, during the automated movement of the fenestration panel 104 relative to the fenestration frame 102.
In another example, the panel operating assembly 400 includes one or more breach sensors 402 configured to detect movement of the fenestration panel 104, operation of the panel actuator 152 or the like, indicative of unpowered movement of the fenestration panel 104 relative to the fenestration frame 102. For instance, in one example, with the fenestration panel 104 in the closed configuration the breach sensor 402 is configured to detect movement of the fenestration panel 104 away from the closed position (e.g., toward the open position). The breach sensor 402, in one example, senses unpowered movement of the panel actuator 152 and registers this as a potential unpermitted opening of the fenestration assembly 100. In another example, a breach sensor such as the breach sensor 158 shown in
In another example, and as described herein, the panel operating assembly 400 is configured to permit manual opening and closing of the fenestration panel 104 while at the same time providing automated opening and closing functionality with the panel actuator 152. The panel shoe 404 permits the selective decoupling of the panel actuator 152 from the fenestration panel 104 to free the fenestration panel for manual movement without interference from or frustration by the panel actuator 152. In one example, a release operator 408 is provided with the panel shoe 404. The release operator 408 is operable to decouple the panel shoe 404 and the panel actuator 152 from a portion of the fenestration panel 104. While decoupled the panel shoe 404 is movable relative to a shoe track 406 provided with the fenestration panel 104 thereby permitting manual movement of the fenestration panel 104 (e.g., a movable configuration). Conversely, while the panel shoe 404 is coupled (e.g., an anchored configuration) the shoe is static relative to the panel track 406 and the fenestration panel, and operation of the panel actuator 152 causes one or more of opening or closing movement.
In one example, the shoe track 406 includes an anchor socket (optionally a component of an anchor guide 414 associated with the shoe track) configured to provide an amount of tolerance between an anchor of the panel shoe 404 and the socket to permit some relative movement between the panel shoe 404 and the shoe track 406 (and anchor guide 414) to permit limited outward movement of the fenestration panel 104 into the revealed position shown in

Referring again to
If automated operation is specified, the user moves the fenestration panel 104, for instance in a closing direction, and the panel shoe 404 approaches the anchor guide 414. Referring again to
In another example, with the shoe anchor 412 decoupled from the anchor socket 416 and movable along the shoe track 406 the panel actuator 152 is optionally actuated to drive the panel shoe 404 along the shoe track 406 toward the anchor guide 414 and the anchor socket 416. In this example, instead of manually moving the panel 104 the panel actuator 152 is moved to re-seat the shoe anchor 412 with the anchor socket 416 and transition the panel shoe 404 from the movable configuration to the anchored configuration.
In another example, the fenestration assembly 100 includes a control interface 804. The control interface 804 is shown as separate from the control module 206. Optionally, the control interface 804 is included with the control module 206 or the control module 206 is included with the control interface 804. The control interface 804, in an example, includes its own processor, memory, circuits or the like. In another example, the control module 206 includes a processor and memory, and the control interface 804 includes a communication device, and interconnections or porting for one or more other components of the fenestration assembly 100. The control interface 804 is optionally connected with one or more of the actuators, such as the panel actuator 152 or latch actuator 300, and controls the corresponding automated function (e.g., opening, closing and maintenance of panel position; latching or unlatching). In another example, the control interface 804 includes an onboard transceiver that controls transmission and reception of information (as a communication interface) between the fenestration assembly 100 and one or more components associated with the fenestration assembly including mobile devices, wall mounted control interfaces, remotes, other fenestration assemblies (e.g., for coordination of opening, closing, securing or the like), HVAC systems or the like. The control interface 804 optionally includes a communication device such as, but not limited to, a radio transceiver, Wi-Fi modem, Wi-Fi router, wired communication port (e.g., for an ethernet cable, fiber optic cable or the like) to facilitate communication between the fenestration assembly 100 and the one or more associated components. The control interface 804 permits the updating of firmware, release or refinement of functions or capabilities, enhancement or expansion of functions or capabilities or the like. In one example, one or more of the control interface 804 or control module 206 is part of an expandable architecture including CAN bus or the like, that permits the addition of different functions and capabilities with the fenestration assembly 100 including, but not limited to light modulation with actuators that operate shades, louvers, blinds, LED lighting; enhanced sensing such as, but not limited to, pressure, wind direction, temperature, ambient light, including one or both of interior or exterior sensing or the like. Additionally, the communication device of the control interface 804 as well as the sensors and processor of the interface 804 (or control module 206) permit one or more of remote diagnostics of the fenestration assembly, alerts regarding detected events (e.g., failures, breaches, environmental events such as rain or the like), as well as over the air updates (e.g., firmware; refinement, release, or enhancement of functions or capabilities or the like).
Optionally, the components of the fenestration assembly 100 that control automated operation thereof, sensors or the like are interconnected with one or more interfaces, including, but not limited to, hard wiring, wireless interconnections, a bus, CAN bus or the like. For example, each of the control module 206, control interface 804 include one or a plurality of ports (e.g., two or more) to permit selective coupling with features of the fenestration assembly 100. The ports include, but are not limited to, universal serial bus (USB), ethernet, other port formats or the like that permit one or more of communication, control of actuators, power provision or the like. The control module 206 or the control interface 804 (e.g., examples of fenestration controllers) are optionally provided with a plurality of ports to permit wired interconnection with each of the sensors, actuators, energy sources (e.g., supercapacitor, low voltage, batteries or the like) and to provide still additional ports permitting interconnection of the fenestration assembly 100 with additional sensors and features including, but not limited to, an indoor temperature sensor, outdoor temperature sensor, pressure sensors (one or more of indoor or outdoor), wind speed sensors, wind direction sensors, light sensors (one or more of indoor or outdoor), moisture sensors, actuators, shade or louver actuators, tint controllers or the like. The processor or processors provided with the control module 206 or the control interface 804 receive and distribute information between sensors, actuators, energy sources or the like according to the various interfaces (e.g., according to CAN bus formatting or the like).
In the example shown in
Optionally, the control interface 804 is coupled with one or more sensors, such as an unpowered movement sensor 802 (e.g., another type of breach sensor) that detects movement of the fenestration panel 104. In one example, the unpowered movement sensor 802 monitors one or both of the fenestration panel 104, the panel actuator 152 or the like to detect movement of the panel (or the actuator) in the absence of automated movement (e.g., unpowered movement). The control interface 804, control module 206 or the like (examples of fenestration controllers) are coupled with the unpowered movement sensor 802 and optionally generate alerts with regard to movement, degree of movement (e.g., from 4 inches open to 12 inches open or the like) or the like that are delivered by way of audible or visible alerts (e.g., at the fenestration assembly 100 with speakers, LED lights or the like) or are provided to associated remote devices, mobile devices (phones or tablets), wall mounted control interfaces or the like. Optionally, the associated fenestration controller for the assembly 100 or a controller for environmental systems for a building act on these alerts to close the fenestration assembly, for instance if the fenestration panel 104 is moved by wind, intruders or the like. In another example, the unpowered movement sensor 802 detects movement of the fenestration panel 104 while the breach sensor 158 detects opening of the fenestration panel 104, such as movement of the fenestration panel from the fully closed position to any open position. The unpowered movement sensor 802 includes, but is not limited to, magnetic, light, ultrasound, encoder sensors or the like coupled with one or more of the fenestration panel 104, fenestration frame 102 or panel actuator 152 to detect, and in some examples quantify, movement of the fenestration panel 104 (or actuator). In another example, the control interface 804 provides and relays information to the fenestration assembly 100 components (e.g., the control module 206) and from the components of the assembly 100 to components associated with the assembly 100, such as mobile devices, wall mounted interfaces, displays, environmental systems such as HVAC systems, other fenestration assemblies or the like.
The control module 206 includes, in one example, a motor control board having a processor configured to control the latch actuator 300 of the panel latch assembly 204. In another example, the control module 206 includes additional porting to permit intercommunication with sensors, such as the breach sensor 800, environment sensor 208 or the like.
The fenestration assembly 100 includes an energy source 808, for instance a battery, port, wiring bundle, or the like to provide power from a low voltage source including residential wiring, batteries, combination of the same, or the like. Optionally, the energy source 808 is coupled with one or more of the control module 206 or the control interface 804 to permit the distribution of power to the various actuators and sensors of the fenestration assembly. In another example, the fenestration assembly 100 includes an energy storage device, such as the energy source 806. In one example, the energy source 806 includes a capacitor, supercapacitor, battery or the like configured to charge and store energy for the fenestration assembly 100, for instance to facilitate operation of one or more of the latch actuator 300 or the panel actuator 152 in combination with low voltage power (energy source 808) or by itself in the instance of power failure, emergent situation or the like.
In operation the fenestration assembly 100 is operated in an automated manner, for instance according to control provided with one or more processors included with the control module 206, control interface 804 or the like. In one example, the environmental sensor 208 is in communication with the control module 206 and senses one or more environmental characteristics including, but not limited to, temperature, moisture, pressure, wind speed, wind direction or the like, including indoor, outdoor or both instances of each characteristic. In one example operation, upon sensing of moisture (e.g., precipitation, humidity or the like beyond a specified threshold) with the environmental sensor 208 the control module 206 initiates closing of the fenestration assembly 100 with the panel actuator assembly 400 (and optionally latching with the panel latch assembly 204), precludes automated opening of the fenestration assembly 100 if already closed, or provides an indication to a user interface that (if closed) opening of the fenestration assembly 100 is not advisable because of moisture. In another example, if one or more of exterior temperature, humidity, wind speed or the like is outside of a specified comfort range (another example of a specified threshold) for the building occupant the control module 206 initiates closing of the fenestration assembly 100. Conversely, as the control module 206 senses achievement of specified thresholds automated opening of the fenestration assembly 100 is conducted. For instance, if one or more of exterior temperature, humidity, wind speed or the like meets corresponding specified thresholds the control module 206 conducts unlatching with the panel latch assembly 204 and opening of the fenestration panel 104 with the panel actuator assembly 400. In a similar manner, upon sensing moisture, such as precipitation, falls below a specified threshold the fenestration panel 104 is opened. Further, various tiers of specified thresholds are in some examples included to graduate one or more of opening or closing of the fenestration panel 104, for instance to intermediate positions based on achieving of the tiered thresholds or based on the magnitude of deviation from thresholds.
In still other examples, one or more of the control module 206, control interface 804 or the like of the fenestration assembly 100 are in communication with a building or home environmental management system, such as a Connected Home system provided by Marvin Windows and Doors. The fenestration assembly 100 optionally senses one or more environmental or status characteristics of the assembly 100 (open, closed, intermediate status, latched or unlatched, secure or unsecure or the like) or proximate to the assembly 100 (e.g., interior, exterior environment conditions or the like), and provides the measured characteristics to the environmental management system through the control interface 804. The environment management system has its own specified thresholds and associated algorithms, generates instructions based on application of the same, distributes instructions to the fenestration assembly 100 (e.g., to the control interface), and one or more of the control module 206 or control interface 804 operates the panel latch assembly 204, panel actuator assembly 400 or the like. In various examples, operation includes conduct of algorithms based on specified thresholds in a manner similar to the operation described herein. In other examples, operation of the fenestration assembly 100 is conducted based on algorithms that coordinate one or more fenestration assemblies 100 (e.g., assemblies in different locations in a building), operation with HVAC systems such as furnaces, heat pumps, air conditioners, cooling towers, fans, air exchangers or the like.
In another example, one or more of the control module 206 or the control interface 804 are in communication with breach sensors, such as the breach sensor 800. The breach sensor 800 senses the status of the of the fenestration assembly including open, closed and optionally intermediate positions of the same. The breach sensor 800 includes a limit switch, reed switch or the like. In another example, the breach sensor 800 is associated with one or more of the actuators of the fenestration assembly 100, such as the panel actuator 152 or the latch actuator 300. In one example, the breach sensor 800 in cooperation with a fenestration controller, such as the control module 206 or the control interface 804 detects movement of the fenestration panel 104 or the actuators 152, 300 in a non-actuated condition, for instance without powered operation of the actuators 152, 300. In such an example, unpowered movement is potentially indicative of a weather related opening or closing of the assembly 100 based on pressure differential or opening of the fenestration assembly 100 by an intruder. The control module 206 or control interface 804, in an example, counters the unpowered movement of the fenestration panel 104 with powered movement to accordingly maintain the fenestration panel 104 in a specified state (e.g., a closed configuration). In another example, the control interface 804 sends an alert from the fenestration assembly 100 to a remote device, mobile device, wall mounted control interface or the like to thereby alert the user to the unpowered movement.
The fenestration controller 902 optionally includes one or more other functions in addition to or instead of ventilation control. For example, as described herein one or both of the panel latch or panel operating assemblies are operated (e.g., with the actuators 924 corresponding to the latching and panel operating actuators) after securing or closing the fenestration panel 104 to back drive the associated actuators. The back driving of the actuators provides tolerance to facilitate manual operation of the fenestration assemblies 100, for instance, in the event of a power failure, emergent situation, failure of the operator interface 906 or the like. Optionally, the fenestration controller 902 automatically back drives the associated actuators to provide the tolerance (see

As further shown in
In another example, the fenestration controller 902 includes a coordination module 922. The coordination module 922 receives one or more characteristics of the fenestration assemblies 100, for instance, detected open and closed conditions, position of the panels 104 (e.g., closed, open or intermediate positions therebetween). The coordination module 922, in one example, cooperates with the ventilation prescription module and dynamic ventilation module 918, 920 to coordinate the opening of one or more of the fenestration assemblies 100 while another fenestration assembly 100 associated with the system is open. For instance, as shown in
In another example, the fenestration system 900 includes one or more environmental systems 926. The environmental systems 926 include, but are not limited to, one or more environmental conditioning units such as a fan, furnace, air conditioning unit or one or more other devices such as a heat pump, geothermal heating or cooling unit or the like. Optionally, the ventilation modulation controller 902 coordinates the operation of one or more of the environmental systems 926 with one or more of the fenestration assemblies 100 in a manner similar to coordination between operation or opening of the fenestration assemblies as previously described hereinabove. For instance, on a warm day operation of the environmental conditioning unit (e.g., a first operational status of an air conditioning unit, such as running or operating) is provided to the coordination module 922. The coordination module 922 accordingly operates a fenestration assembly 100 associated with an upper portion of a home (e.g., a skylight, upper floor window or the like). Operation of the fenestration assembly 100, for instance, through the actuator (or actuators 924) is automatically controlled by the coordination module 922 to coincide with the operation of the air conditioner. Accordingly, as cool air is delivered to the house the fenestration assembly 100 is opened with the actuators 924 (e.g., the panel latch and panel operating assemblies) to exhaust heated air otherwise trapped in the building. Conversely, with cessation of operation (e.g., a second operational status, for instance including a blower shut off or the like) the coordination module 922 optionally initiates closing of the fenestration assembly 100 with the actuators 924, for instance to prevent the escape of cooler air. In another example, the fenestration assembly 100 is left open to facilitate additional exhaust of warm air as the warm air rises to the fenestration assembly 100.
As further shown in
In another example, fenestration system 900 includes one or more comfort parameters corresponding to exterior conditions that are considered comfortable. In some examples, the comfort parameters vary (sometimes significantly) from interior conditions that are considered comfortable (e.g., room temperature). The comfort parameters, in one example, include a range of temperatures, humidity, wind speed or combinations of the same that are considered comfortable to an occupant when outside. The sensors 904 monitor these exterior conditions, and upon detection of exterior characteristics approaching or satisfying the comfort parameters the ventilation modulation control 902 operates one or more of the fenestration assemblies 100 (the actuators 924) to open the assemblies and accordingly bring the exterior conditions into the building. In one example, the fenestration assemblies 100 and the fenestration system 900 permit the virtual creation of an exterior comfortable environment within the building interior.
As further shown in
In another example, each of the components, such as the controller 902, operator interface 906, sensors 904, fenestration assemblies 100 and environmental systems 926, are interconnected with one or more wireless connections including, but not limited to, wireless connections provided by a wireless modem, network or the like (Bluetooth, IEEE 802.11 standard, near field, infrared, radio frequency or the like). The interface wirelessly interconnects each of the components to facilitate their communication and control of one or more of the components including, but not limited to, the fenestration assemblies 100, environmental systems 926 or the like. In another example, the interface 908 includes a mixed series of interconnections. For instance, the operator interface 906 is, in one example, interconnected with the ventilation modulation controller 902 with a hardwired connection such as an Ethernet connection, bus or the like. In contrast, the fenestration assemblies 100 are, in various examples, wirelessly connected with one or more of the ventilation modulation controller 902 (or controllers, for instance provided with each fenestration assembly 100) or operator interface 906. The wireless interconnections further permit one or more of remote diagnostics to assess faults, failures or issues with the fenestration assemblies 100; detect events such as breaches or uncontrolled movement of the fenestration panels 104; or conduct over the air updates of firmware, expand or improve functions, add additional functions to the fenestration assemblies 100 or the system 900 or the like.
The fenestration assembly 100 (e.g., a component of the ventilation fenestration system 900), is operated according to one or more ventilation prescriptions. In one example, the ventilation modulation controller 902 includes a warm weather ventilation prescription. For instance, with an elevated exterior temperature relative to an interior temperature of the building zone 1000 an air conditioner (an example environmental system 926) cools the building zone 1000 to a specified set point such as room temperature or comfort parameters corresponding to exterior conditions that are considered comfortable. In some examples, the comfort parameters vary from interior conditions that are considered comfortable (e.g., room temperature) and may, in an example, include a range of temperatures, humidity, wind speed or combinations of the same that are considered comfortable to an occupant when outside. In another example, warm air is accumulated in the upper portions of the building zone 1000, for instance, proximate to the fenestration assembly 100. The ventilation modulating fenestration system 900, including one or more of the modules 918-922, exhausts the accumulated heated air through opening of the fenestration assembly 100, for instance with operation of the panel latch and panel operating assemblies described herein.
Optionally, a thermometer (e.g., temperature sensor 910 of the fenestration sensors 904) is associated, in one example, with the fenestration assembly 100. For example, the thermometer is installed along the fenestration frame or proximate to the assembly 100 (e.g., along a ceiling, wall or the like). As the temperature rises proximate to the temperature sensor 910 (e.g., above a set point such as room temperature) the ventilation modulation controller 902 having the warm weather ventilation prescription opens the assembly by way of the dynamic ventilation module 920 and the operator actuators 924 (e.g., one or both of the panel latch and panel operating assemblies). Opening of the fenestration assembly 100 exhausts or vents accumulated higher temperature air in the building zone 1000 and accordingly enhances the cooling of the building zone 1000. In one example, operation of an air conditioner is minimized because heated air is exhausted and thereby not cooled with the conditioned air. In other examples, exhausting of the accumulated hot air facilitates the cooling of the building zone 1000 without operation of the environmental system 926. For instance, as heated air is exhausted through the fenestration assembly 100, a lower temperature is more readily maintained within the building zone 1000 without operation or with minimal operation of the environmental system 926.
Another example ventilation prescription is optionally stored or input to the ventilation prescription module 918. In this example prescription cooler weather, wind, breeze or the like (e.g., exterior temperature or exterior wind characteristic) is a control input for opening (and closing) of the fenestration assembly 100 with the actuators 924. For instance, with a breeze or wind greater than a specified threshold (e.g., wind speed, temperature, combination of both or the like) included in the prescription module 918 the dynamic ventilation module 920 opens the fenestration assembly 100 with the actuators 924 to institute a draft through the building zone 1000 and cool the building therein. Opening of the fenestration assembly 100 according to this prescription exhausts stagnant air from the building zone 1000 and brings exterior (comfortable) air into the zone 1000. In another example, opening the fenestration assembly 100 exhausts heated air captured near the upper portion of the building zone 1000 (e.g., in bedrooms). For instance, during the summer or winter heated air accumulates in the upper portions of a building through operation of a furnace or falling of cooled conditioned air and rising of stagnant heated air). The exhaust prescription described herein facilitates the rapid exhaustion of the heated air to provide a pleasant environment for sleeping, occupancy or the like. Optionally, the prescription compares the exterior and interior temperatures and the actuators 924 are actuated to open the assembly (or assemblies) with a sufficient deviation between the exterior and interior temperatures that satisfy a prescription. Alternatively, where comfort parameters for the exterior environment are achieved the fenestration assembly 100 is opened to permit the introduction of comfortable exterior conditions (e.g., temperature range, humidity range, wind speed or draft) to the interior environment of the building zone 1000.
In still another example, the ventilation prescription module 918 includes a prescription that bases operation of the fenestration assembly 100 (e.g., opening, closing, and intermediate positions of the panel 104) on measured humidity including dew point. In this example, if the humidity of the exterior environment measured with the moisture sensor 914 is below a specified threshold of humidity (e.g., a dew point of 55 degrees or less) the fenestration assembly 100 is opened to permit the exchange of dryer exterior air (e.g., fresh air) with the previous interior air.
In another example, enhanced humidity is specified for the building zone 1000, for instance, after continuous or near continuous operation of an air conditioner or furnace interior humidity may fall to uncomfortable levels (e.g., dew points of 45 degrees or less). In this example, the ventilation prescription initiates opening of the fenestration assembly based on an assessment of the exterior humidity relative to the interior humidity. For instance, the prescription module 918 includes an if/then rule, such as if the interior dew point is less than 45 degrees and the exterior dew point is greater than 45 degrees then the dynamic ventilation module 920 initiates opening of the fenestration assembly 100 with the actuator 924 to humidify the interior air. One or more conditions are added to the prescription in another example, including a temperature condition (e.g., if the temperature is greater than 80 degrees Fahrenheit or less than 20 degrees Fahrenheit) that overrides the opening of the fenestration assembly 100 to maintain a specified temperature in the building.
As shown in
In other examples, the fenestration system 900 includes a plurality of fenestration assemblies 100 including one or more skylights, windows, doors or the like. In various examples, these fenestration assemblies 100 are provided around a building, for instance, facing in various directions, orientations or the like. The fenestration system 900 optionally coordinates the opening of the one or more fenestration assemblies 100 to enhance the draft or breeze through one or more building zones 1000. For instance, in a scenario including a wind direction from west to east corresponding fenestration assemblies 100 are opened to enhance the draft and ventilation through the building. The fenestration system 900 includes a wind characteristic sensor 912 that detects the west to east wind direction. The ventilation modulation controller 902 accordingly coordinates, by way of the coordination module 922, the opening of corresponding fenestration assemblies 100 provided on the west and the east portions of the building. The pressure differential on the windward (west) and leeward (east) sides initiates a corresponding draft or breeze through the building. In this example with coordination of fenestration assembly 100 operation a breeze, draft or the like is permitted through the building zones 1000 that correspondingly facilitates conditioning of the interior environment.
Optionally, the ventilation prescription module 918 is configured to accept operator prompts, for instance, from the operator interface 906, shown in
In another example, one or more moisture sensors 914 are included with the fenestration assemblies 100 or are components of the fenestration system 900. In one example, the moisture sensors measure or detect precipitation (e.g., rain, snow or the like), humidity or the like. A specified precipitation threshold (rain drops per unit time, inches of precipitation, humidity or dew point or the like) is a set point included with one example of a moisture based ventilation prescription. In a scenario including rain, snow or the like that exceeds the specified precipitation or humidity threshold the dynamic ventilation module 920 automatically initiates closing of the fenestration assemblies 100 (e.g., optionally overriding other ongoing ventilation prescriptions) with the actuators 924 (panel operating assemblies) to prevent the ingress of moisture. In another example, the moisture sensors 914 are used in combination with the ventilation prescription module 918 to trigger opening, for instance, after cessation of precipitation. After the monitored precipitation or humidity falls beneath the specified precipitation threshold the dynamic ventilation module 920 automatically opens the fenestration assemblies 100 in compliance with one or more ventilation prescriptions, such as ongoing prescriptions that were previously overridden because of precipitation.
