The copyright owner has no objection to the facsimile reproduction by anyone of the patent document or the patent disclosure, as it appears in the Patent and Trademark Office patent files or records, but otherwise reserves all copyright tights whatsoever. The following notice applies to the software and data as described below, and in the drawings, that form a part of this document: Copyright Marvin Lumber and Cedar Company d/b/a Marvin Windows and Doors, Warroad, Minn., All Rights Reserved.
This document pertains generally, but not by way of limitation, to status monitoring of fenestration assemblies including windows and doors.
Fenestration assemblies including door assemblies, window assemblies, and the like have one or more movable panels such as sashes or doors. The panels are movable relative to respective window and door frames. Security features are provided to fenestration assemblies to facilitate closing and locking of the assemblies to according secure a home, building or the like.
Confirmation of closing and locking of a fenestration assembly is accomplished in some examples with a plurality of sensors. Each sensor is configured to detect a status of the fenestration assembly. For instance, in one example, a sensor is provided to detect whether the door or sash of the fenestration assembly is closed. Another sensor (second sensor) is provided to detect if the door or sash is locked. The status of each sensor including detection of a closed condition by the first sensor and a locked condition by the second sensor is, for example, provided to a user remotely to indicate both status conditions of the assembly. That is to say open/closed and locked/unlocked status indicators for the fenestration assembly are provided to a user.
In another example, the output of the sensors including open/closed conditions from a first sensor and locked/unlocked conditions from a second sensor are interpreted by a controller (e.g., processor, memory, program or the like) to determine if the fenestration assembly is secure or unsecure. The controller provides a secure status if both the closed and locked conditions occur at the same time. However, if the first sensor detects the open condition and the second sensor detects either of the locked or unlocked conditions, the controller provides an unsecure status. Similarly, if the second sensor detects the unlocked condition and the first sensor detects either of the open or closed conditions the controller provides an unsecure status. Stated another way, the controller is provided with an algorithm that in effect provides a flow chart to determine the secure or unsecure status of the fenestration assembly.
The present inventors have recognized, among other things, that a problem to be solved includes reducing the number of sensors and supporting components needed to determine if a fenestration assembly is secure (closed and locked) or unsecure. In some examples, status monitoring systems use a plurality of sensors. Each of the plurality of sensors are configured to detect a separate condition of the assembly. For instance, a first sensor detects the locked/unlocked condition and a second sensor detects the closed/open condition. Spacing for the sensors is provided in or on the fenestration assembly. Where the sensors are provided in the fenestration assembly routing, molding or the like is used to provide sufficient space for the sensors. Where the sensors are provided on the fenestration assembly the aesthetic appeal of the assembly is decreased because of the visible installed sensors. Further, where a controller is used to interpret the conditions from the various sensors and output one or more status indicators for the fenestration assembly, additional space is allocated within the fenestration assembly for the controller, or optionally, the controller is fastened to the exterior of the fenestration assembly (thereby further decreasing the aesthetic appeal). Further still, the controller provides additional expense and labor for the status monitoring assembly because of additional electronics, coding (for algorithm) or the like.
The present subject matter provides a solution to this problem, such as by providing a status monitoring assembly including a sensor (e.g., sensor, switch or the like) configured to provide a secure status indicator with the fenestration assembly closed and locked. In one example a sensor and a sensor operator (e.g., a sensor assembly) are installed with the fenestration assembly. The sensor is configured to detect the sensor operator when the fenestration assembly is closed (e.g., the door, sash, or sashes are closed) and the locking mechanism is locked (e.g., a latch is coupled with a latch fastener). When both of these conditions are satisfied the sensor operator is detected by the sensor and a secure status for the assembly is achieved. In other permutations or conditions, where one or more of the panel is open or the locking mechanism is unlocked, the sensor fails to detect the sensor operator and accordingly the status monitoring assembly provides an unsecure status (including a failure to indicate the system is secure). Relatively complex logic (i.e., flowchart type algorithms) and associated controllers that assess multiple conditions from multiple sensors and output a status based on the assessment are thereby avoided.
The status monitoring assembly described in the examples herein thereby determines the secure and unsecure status through a consolidated system including one or more sensors (as opposed to requiring at least two sensors). Further, the status monitoring assembly performs this function without the use of a controller, algorithms, subscription to a service that broadcasts and optionally interprets) status data from the fenestration assembly or the like. Instead, the secure or unsecure status of the status monitoring assembly is in one example readily broadcast with a wireless transceiver (including a transmitter) and received at an output device at the home or with the user (e.g., a smartphone, tablet or the like).
Because the status monitoring assemblies described herein use a sensor and sensor operator and do not require multiple sensors, the integration of the assemblies with fenestration components (e.g., frames, doors, sashes or the like) is facilitated relative to the multiple components of other status monitoring systems having plural sensors, a controller and the like. Accordingly, routing of recesses and routing of interconnections for power and transmission (where included) are thereby reduced, and the status monitoring assemblies (including a sensor assembly, power source, transceiver or the like) are readily integrated with fenestration assemblies. Further, because of the minimal number of components, the status monitoring assembly is readily concealed within fenestration assemblies to maintain the aesthetic appeal of the assembly.
This overview is intended to provide an overview of subject matter of the present patent application. It is not intended to provide an exclusive or exhaustive explanation of the invention. The detailed description is included to provide further information about the present patent application.
In the drawings, which are not necessarily drawn to scale, like numerals may describe similar components in different views. Like numerals having different letter suffixes may represent different instances of similar components. The drawings illustrate generally, by way of example, but not by way of limitation, various embodiments discussed in the present document.
Described herein are various configurations of devices and methods of a status monitoring assembly, for instance, for determining if fenestration units windows and doors) are secure (closed and locked) or unsecure (one or more of open or unlocked). The following examples and drawings illustrate the subject matter to enable those skilled in the art to practice the subject matter described in the following detailed description. Portions and features of some examples may be included in, or substituted for, those of other examples.
The fenestration assemblies described herein detect a secure configuration (and conversely an unsecure configuration) with use of a single integrated sensing system. In contrast, some other example products require multiple sensors to perform the same function. For instance, one sensor detects the open/closed status and another sensor detects the locked/unlocked status. One or more of dual indicators or logic algorithms are used to assess whether the corresponding fenestration unit is both closed and locked.
In examples of a casement fenestration family of products, the sensor is attached to a tie bar in a window frame. A sensor operator, for instance, a ferrous metal (or magnet) is located on a keeper. The sensor operator is attached to a sash (e.g., a casement window panel). In this configuration the status monitoring assembly detects the secure configuration if the sash is closed and the locking hardware is engaged in the locked position (e.g., a latch such as a latch bolt is coupled with the latch fastener such as a keeper). Optionally, there are no wires, cables or the like in the sash.
In one example of a double hung fenestration family of products, the sensors (one for each sash) are over provided in the latch receivers (e.g., latch fasteners), for instance, over molded into the receivers/recesses. The sensor operators for each of the panels, such as the respective top and bottom sashes, including but are not limited to ferrous, magnetic components or the like. The sensor operators are coupled with the respective latches (e.g., over molded, adhered, integral to the latch bolts or the like).
Optionally, for a bottom sash, a first sensor is provided to detect the locked and fully closed position, while a second sensor is provided to detect the locked and vent mode position (e.g., open approximately four inches). The status monitoring assembly is thereby able to sense at least two secure configurations (labeled ‘secure’ for the first and ‘venting’ for the second) with the bottom sash at the respective positions and the latch (latch bolt) and the sensor operator received in corresponding latch recesses (e.g., latch fastener) and sensed by the first or second sensor. For a top sash, a sensor is provided for the locked and closed position. In another example, the top sash and corresponding portions of the frame include first and second sensors corresponding to a closed and locked and locked and venting configurations as with the bottom sash.
With these status monitoring assemblies including the sensor and the sensor operator, even if the locking mechanism is positioned in the locked position (for instance an upper rail mounted latch operator), the sensors (first or second) will detect locked and closed (secure) or locked and vented (venting) if the sash is in fact in the locked and closed or locked and vented positions. This configuration also al lows each sash to detect locked and closed (secure) or unlocked or open (unsecure) configurations independently of one another. Optionally, there are no wires, cables or the like used in the window sashes.
In one example of a glider fenestration family of products, the sensor is coupled with the keeper (e.g., latch fastener) on a second sash. The sensor operator (e.g., a ferrous pin, magnet or the like) is coupled with the latch (e.g., integral to the bolt) on a first sash. With this configuration the glider fenestration unit is one or more of an XO, OX, XX, XOX, or OXXO configured unit (with X meaning a movable sash, O meaning a stationary sash, and the total number of O and X indicating the number of sashes in the unit). In a multiple sash embodiment with two or more sashes there is one sensor per pair of meeting stiles configured to monitor if the window (e.g., the instant pair of sashes at the respective meeting stile are closed and locked or unlocked or open).
In an example, an interface is provided including biased (e.g., spring loaded) contacts between one or more of the sashes and the fenestration frame. For instance, spring loaded contacts are provided in a power and data interface (frame interface) of the frame header and corresponding contacts are provided with the sensor assembly interface (panel interface) along a top meeting rail of the second sash. With the second sash in the closed position the status monitoring assembly, including the sensor assembly, is able to detect the sensor operator of the first sash because of electrical contact between the interfaces. Electrical continuity is thereby maintained between the frame of the fenestration unit and the second sash (as well as the first sash in its closed and locked position) without the need for wires. Accordingly, the second sash (having the sensor) is optionally removeable without needing to disconnect any wires or connectors.
In examples of door fenestration units of this disclosure, a cam surface (sensor operator) and a detect switch (sensor) are included in the locking mechanism between a face plate and key access point on an exterior of the door. When an operator or key is used to move the latch (e.g., deadbolt) the cam surface rotates causing the detect switch to change state (e.g., actuate), thereby indicating that the door panel is locked. A release feature in the locking mechanism is pushed in to allow the latch to move. The release feature is operable with the door panels in a closed position. Accordingly, the status monitoring assembly, for instance the sensor, detects the sensor operator with the door in the closed and locked configuration.
In another example, the fenestration unit, for instance a door unit, includes a second sensor assembly configured to monitor opening and closing of a panel such as a door. Accordingly, such a fenestration unit is configured to monitor a secure and unsecure configuration as described herein, and in some examples, also provides a separate notification of opening and closing of the panel (e.g., a door).
Optionally, the sensors used in the fenestration units are part of an overall system for processing and outputting sensor signals by a circuit card assembly (CCA). The CCA is optionally integrated into the window, for instance in a transceiver and power source (e.g., battery) are provided in a recess in one or more of the fenestration frame or panel. The CCA wirelessly broadcasts the sensors status on a radio frequency used by a bridge, professional installer, or similar device to inform an end user if the corresponding fenestration unit is closed and locked (secure) or unlocked or open (unsecure).
In one example, the systems described herein are factory installed and do not require a professional installer to integrate into a home automation system. Instead, the systems are configurable to broadcast on wireless frequencies for reception by an application (e.g., on a smart phone, tablet, personal computer, read out or the like). Professional installation and integration of the units is thereby minimized (e.g., reduced or eliminated). Further, communication and installation of third party security systems is optional to use the herein described systems as each of the systems is optionally configured to operate on its own.
The first panel 104 and the second panel 106 are moveable between open and closed positions. For instance, the first panel 104 and the second panel 106 are moveable relative to each other and the fenestration frame 102. As shown in
In the example of
As shown and described in the following examples, the fenestration assembly, for instance fenestration assembly 100, includes a status monitoring assembly 103 configured to monitor the secure and unsecure configurations. In various examples, the status monitoring assembly 103 includes a sensor, and a sensor operator. The sensor includes, but is not limited to, a magnetic switch (e.g., reed switch, balanced reed switch, magnetic sphere switch or the like), magnetic sensor, hall effect sensor, mechanical switch, electromechanical switch, electronic switch, ferrous proximity switch (e.g., inductive sensor), mercury tilt switch or other sensor used to detect proximity (or other proximity sensor or switch) or the like. The sensor operator includes, but is not limited to a ferrous metal (including ferrous metals and magnets), a mechanical contact, an electrical contact or the like. In some examples, the sensor is coupled to the latch fastener (such as the keeper) and the sensor operator is coupled to the latch, the panel, or the frame 102. In one example, the sensor detects when the latch (the latch acting as the sensor operator) is coupled with the latch fastener. In a further example, the sensor detects the sensor operator if the panel is in the secure configuration (e.g., with the panel in the closed position and the latch coupled with the latch fastener). The status monitoring assembly 103 provides a notification indicating the configuration of the fenestration assembly (e.g., one or more of the secure or unsecure configurations). Accordingly, the status monitoring assembly 103 detects the secure configuration (e.g., one or more panels in the closed position and one or more latches coupled with one or more respective latch fasteners) with a single sensor. Optionally, in further examples, a second or a plurality of sensors are used to detect the status of the fenestration assembly 100.
In some examples, the status monitoring assembly 103 includes a module 114. The module 114 includes, but is not limited to, one or more of a hard wired connection, a transceiver (e.g., including wired or wireless, transceivers or transmitters), power source (e.g., battery or power socket), controller, or the like. In a further example, the status monitoring assembly 103 operates without the use of a dedicated controller, algorithm, subscription to a service that broadcasts (and optionally interprets) status data from the fenestration assembly 100, or the like. For instance, the secure or unsecure status of the status monitoring assembly 103 is broadcast with the module (e.g., wireless transceiver) and received at an output device at the home or with the user (e.g., a smartphone, tablet, in home or building network, internet of things hub or the like).
In the example shown in
The sensor 124, in the example of
In one example, the locking mechanism 101 includes a release 142. One example of the release 142 is described in the Provisional Patent Application Ser. No. 62/447,295, which is incorporated by reference herein in its entirety. The release 142 prohibits the latch 108 from moving from the decoupled configuration (e.g., retracted position) to the coupled configuration (e.g., extended and latched position) unless the release 142 is engaged with the latch fastener 120 or the second panel 106. For instance, when the first panel 104 or the second panel 106 are in the open position, the release 142 is extended from the panel 104. Closing of the sashes engages the release with the 142 with the latch fastener 120 or the second panel 106. The movement of the engaged release 142 frees the operating mechanism (e.g., including the operator 118) to move the latch 108 from the withdrawn (
As shown in the example of
In various examples, the status monitoring assembly 103 includes a module 114 including, but not limited to, a controller, transceiver (including a transmitter), power source, or combinations thereof as described herein. The sensor 124 is in electrical communication with the module 114 to communicate the detection of the secure and unsecure configurations. In the example of
In a further example, where the sensor 124 is coupled to the frame 102 or to a non-operative (e.g., fixed) panel, the sensor 124 is hardwired to the controller. For instance, in the example of a single hung window, the second panel 106 is fixed to the frame 102. The wire 115 is concealed within the second panel 106 and extends through the frame 102 to provide electrical communication between the sensor 124 and the controller or to communicate power between a power source and the sensor 124. For instance, the power source includes a battery or power socket providing power to one or more of the sensor 124, controller, or the transceiver. In one example, the module includes the controller or control module. In various examples, the module (e.g., power source, the transceiver, or wires) are concealed within the panel 106, for example, within one or more of the rails or stiles (e.g., rails 110A, 112A, 112B, 111A, 111B, or 113A) of the panel. In a further example, the module 114 is concealed, at least partially, within the frame 102. Accordingly, the status monitoring assembly 103 is operable (e.g., communicates the secure or unsecure status of the fenestration assembly 100) while also concealed from view. The status monitoring assembly 103 described herein thereby maintains the aesthetic appeal of a fenestration assembly including monitoring assembly.
In a further example, the status monitoring assembly 403 includes the panel interface 417 (e.g., sash interface) coupled to the first panel 404 and at least one frame interface 419 coupled to the frame 402. In one example, the frame interface 419 is electrically coupled (e.g., hardwired) to a module 414 including, but not limited to, one or more of a transceiver, controller or power source. In further examples, the fenestration assembly 400 includes a plurality of panel interfaces coupled to respective panels of the fenestration assembly, and these panel interfaces are coupled to a corresponding plurality of respective frame interfaces when the respective panels are closed. For instance, when the first panel 404 is closed (e.g., in the closed position), the status monitoring assembly 403 is communicatively coupled to one or more of the transceiver, controller, power source (e.g., module 414), or the like, through the panel interface 417 and the frame interface 419. In some examples, the module 114 (e.g., transceiver, controller, or power source) is optionally concealed within the frame 402. In the example of
The locking mechanism 401 includes a latch 408 (similar to the latch 108) and a latch fastener 420 (similar to the latch fastener 120) as previously described herein. In a locked position, the latch 408 (e.g., latch blade) is coupled to the latch fastener 420 (received in a latch recess 422). In the unlocked position, the latch 408 is decoupled from the latch fastener 420. The locking mechanism 401 includes an operating mechanism 407. For instance, the operating mechanism 407 includes in an example the operator 118 (e.g., handle, lever, slider, grip, button, crank, or the like), operator housing 116 and latch 420, as previously described. In a further example, the locking mechanism 401 includes the release 142 (as shown in
The panel interface 417 is configured for electrical communication with the frame interface 419. The frame interface 419 and the panel interface 417 include, but are not limited to, fixed contacts, spring contacts, spring probes or the like. The frame interface 419 is attached to the frame 402, for example, at a position to engage with the panel interface 417 when the first panel 404 is in the closed position. The panel interface 417 is optionally positioned on one of the first panel 404 or the second panel 406 or both. In the example shown in
In one or more examples, the latch bolt 426 couples an upper portion of the first panel 404 (e.g., an upper rail 410) to the frame channel 423 within the frame 402. As shown in the example of
A tie element 428, such as a tie bar, is configured to translate within the upper rail 410 based on the movement of the operator 118 (e.g., one or more of rotation or translation movement). Accordingly, the latch bolt 426 is translated between a coupled configuration and a sash tilt configuration corresponding to the position of the operator 118. As shown in the example of
The first panel 404 includes an open, a closed, and a tilted position. Where the latch bolt 426 is withdrawn from the frame channel 423, as shown in the example of
The example of
In a further example, where the release 142 is disengaged from the latch fastener 420 or the second panel 406 or the latch 408 is otherwise positioned in the unlocked position, the unsecure configuration is detected based on the unlocked configuration of the locking mechanism 401, even though the panels 404, 406 in the closed positions and the panel interface 417 is engaged with the frame interface 419 (e.g., because the latch is withdrawn and detected by the sensor).
In another example, wherein the fenestration assembly includes the latch bolt 426, and the latch bolt 426 is withdrawn from the channel 423, the unsecure configuration is detected even though the panels 404, 406 are closed and the locking mechanism is in the locked configuration based on the open circuit caused by the panel interface 417 (on the latch bolt 426) disengaged with the frame interface 419 (electrical contacts coupled to the frame 402).
In one example of the fenestration assembly 400 (as shown in
In one example of the secure configuration, the first panel 404 and the second panel 406 are in the closed positions, the latch 408 is coupled with the latch fastener 420, and the panel interface 417 is electrically coupled with the frame interface 419. In a further example, the locking mechanism 401 includes the release (release 142 as shown in
As shown in the example of
In some examples, monitoring the secure and unsecure configurations of the fenestration assembly 400 includes monitoring the closed or open positions of a second panel (the second panel 406) or other panels of fenestration assemblies. In the example of
In a further example, the second panel 406 includes a second panel interface (similar to the panel interface 417 as previously described) engaged with a second frame interface (similar to the frame interface 419) when the second panel 406 is in the closed position. A second locking mechanism is communicatively coupled to report the status of the second panel 406 through the second panel interface and second frame interface. In a further example, the second panel 406 includes a panel interface configured as a jumper to complete a circuit routed through a second frame interface when the second panel 406 is in the closed position. Correspondingly, the status monitoring assembly detects when the second panel 406 is in the closed position.
The fenestration assembly 500 includes a locking mechanism 501 having an operating mechanism 507 and an operator 518. In one example, the operating mechanism 507 includes, but is not limited to, a bracket 506, a tie bar 528, a latch 508, and a latch fastener 520. The bracket 506 is coupled to the frame 502 and supports the tie bar 528. The tie bar 528 is movably (e.g., slidably) coupled to the bracket 506 and translatable with respect to the frame 502. The latch 508 is coupled to the tie bar 528. For instance, the latch 508 includes an engagement rail 509 (e.g., blade) coupled to the tie bar 528. The operator 518 (e.g., a handle) is operatively coupled to the tie bar 528. The tie bar 528 is translatable based on movement of the operator 518 between an actuated and an unactuated position. Accordingly, the operator 518 translates the latch 508 based on the translation of the tie bar 528 to correspondingly engage the latch fastener 520. For instance, the pin 522 of the latch fastener 520 engages with the rail 509 of the latch 508 and move along the rail 509 as the latch 508 translates (e.g., upward in the example of
The latch fastener 520 is coupled to the panel 504. For instance, the latch fastener 520 is coupled to the side rail 511 of the panel 504. In the example of
A status monitoring assembly 503 includes a sensor 530 and a sensor operator 532. The sensor 530 and the sensor operator 532 include, but are not limited to, the sensors and sensor operators as described herein. For instance, the sensor includes, but is not limited to a reed switch, magnetic sphere switch, or the like. In the example of a reed switch or magnetic sphere switch, the sensor operator includes, but is not limited to, a magnet. In other examples the sensor 524 and sensor operator 527 is one or more of the types previously described herein. In one example, the sensor 530 is attached to the rail 509 of the latch 508. In the example of
In the example of
The sensor 630 is communicatively coupled to the status monitoring 603 assembly. For example, the sensor 630 is communicatively coupled to a module 614 (similar to the module 114, 414, or 514 previously described herein) of the status monitoring assembly 603 by a wire 615. In one example, where at least one of the first panel 604 or the second panel 606 are non-operative (e.g., fixed in the frame 602), the wire is routed through the frame 602 into the respective panel and to the status monitoring assembly 603. For example, the sensor 630 is communicatively coupled to the module 614.
In a further example, the fenestration assembly 600 includes the panel interface 617 and a frame interface 619. The panel interface 617 is coupled to at least one of the first panel 604, the second panel 606, or both. In the example of
As described in other examples herein, the fenestration assembly 700 includes a status monitoring assembly 703. The status monitoring assembly 703 includes a sensor 730 and sensor operator 732. In the example shown in
In one example, a module 714 (e.g., similar to the module 114, 414, 514, and 614 as previously described herein) is located within the frame 702 as shown in the example of
The sensor 824 is coupled with the panel 804. For instance, the cam spindle 844, cam face 846, and the sensor 824 are optionally supported by an operator housing 816 attached to the panel 804. In various examples, the sensor 824 includes, but is not limited to, a switch (e.g., detect switch 124 as shown, for instance, in
Optionally, the locking mechanism 801 includes a release 842. The release 842 prohibits the latch 808 from moving from the decoupled configuration (e.g., retracted position) to the coupled configuration (e.g., extended and latched position unless the release 842 is engaged with a strike plate 844 on the frame 802. For instance, when the panel 804 is in the open position, the release 842 is extended from the panel 804. The release 842 frees the operating mechanism (e.g., including the operator 818) to move the latch 808 when the panel 804 is in the closed position. In one example, the release 842 includes a mechanical linkage operatively coupled with the spindle 844 and the operator 818. Accordingly, in the example of
In a further example, the fenestration assembly 800 includes a panel interface and a frame interface (e.g., the panel interface 617 and frame interface 619 as previously described herein). The panel interface is communicatively coupled with the frame interface when the panel 804 is closed. Accordingly, the sensor 824 reports the secure configuration only when the panel 804 is closed and the cam spindle 844 is in the locked configuration.
As shown in the example, of
In a further example, the fenestration assembly 900 includes a status monitoring assembly 903 including a sensor 930 and a sensor operator 932 as previously described. The sensor 930 is coupled to the panel 904. In the example of
Optionally, the locking mechanism 901 includes a release 942. The release 942 prohibits the latch 908 from moving from the decoupled configuration (e.g., retracted position) to the coupled configuration (e.g., extended and latched position) unless the release 942 is engaged with a strike plate 944 on the frame 902. For instance, when the panel 904 is in the open position, the release 942 is extended from the panel 904. The release 942 frees the operating mechanism (e.g., including the operator) to move the latch 908 when the panel 904 is in the closed position. In one example, the release 942 includes a mechanical linkage operatively coupled with the engagement member 950 and latch 908. Accordingly, in the example of
In one example, the fenestration assembly 900 includes a panel interface and a frame interface (similar to the panel interface 617 and frame interface 619 as previously described herein). The panel interface is communicatively coupled with the frame interface when the panel 904 is closed. Accordingly, the sensor 930 reports the secure configuration only when the panel 904 is closed and the sensor 930 detects the sensor operator 932 (e.g., the locking mechanism 901 is locked). For instance the sensor 930 is communicatively coupled to a module 914 (similar to the modules 114, 414 as previously described herein) of the status monitoring assembly 903 by a wire. Accordingly, the sensor 930 is communicatively coupled to the module 914.
At 1010, at least one panel is moved between an open position and a closed position relative to a fenestration frame. Moving the at least one panel includes, but is not limited to, one or more of moving a first sash between respective open and closed positions or moving a second sash between respective open and closed positions. For instance, the first sash or the second sash is a first panel or a second panel of a double hung window assembly, a sliding window assembly, a glider window assembly, a sliding door assembly, a casement window assembly, a hinged door panel assembly or the like.
At 1020, at least one latch or latch fastener is moved between coupled and decoupled positions relative to the other of the latch fastener or the latch. In various examples, the latch is coupled with the first sash and the latch fastener is coupled with the second sash. Moving the latch or latch fastener relative to the other of the latch fastener or the latch optionally includes receiving a latch bolt within a latch recess. In one example, a first latch is moved relative to a first latch fastener between a coupled and a decoupled configuration, where the first sash (e.g., first panel) is fixed (e.g., held static) with respect to a frame. In a further example, the first latch fastener is moved relative to the first latch between the coupled and the decoupled configuration, where the first sash is fixed with respect to the frame. In another example, a second latch is moved relative to a second latch fastener between the coupled and decoupled position, where the second sash (e.g., second panel) is fixed with respect to the frame (e.g., held static). In yet a further example, the second latch fastener is moved relative to the second latch between the coupled position and the decoupled position where the second sash is held static.
At 1030, a secure and an unsecure configuration of the fenestration assembly are monitored with a status monitoring assembly. The status monitoring assembly includes a sensor and a sensor operator. In one example, the sensor operator and the sensor include a first sensor operator and a first sensor. Monitoring the secure and unsecure configurations of the fenestration assembly optionally includes monitoring secure and unsecure configurations of the first sash. In a further example, the sensor operator and the sensor include a second sensor operator and a second sensor. Monitoring the secure and unsecure configurations of the fenestration assembly includes monitoring at least one of the secure and unsecure configurations of the second sash, the secure and unsecure configurations of the first sash, or both. Monitoring for the secure and the unsecure configurations optionally includes at least the steps of 1032 and 1034 below.
At 1032, the sensor fails to detect the sensor operator if at least one of the panels are in the open position or the latch is decoupled from the latch fastener. In one example, an unsecure configuration notification is provided (e.g., by the status monitoring assembly) if the sensor operator is not detected by the sensor. In various examples, the first sensor fails to detect the first sensor operator if the first sash is in the open position, or the first latch is decoupled from the first latch fastener. The second sensor fails to detect the second sensor operator if the second sash is in the open position or the second latch is decoupled from the second latch fastener, or any combination thereof.
At 1034, the sensor communicates the detection of the sensor operator if both the panel is in the closed position and the latch is coupled with the latch fastener. Optionally, detecting the sensor operator with the sensor includes detecting a magnet with a magnetic sensor (e.g., a reed switch or magnetic sphere switch, such as those manufactured by the Magnasphere Corporation of Waukesha, Wis.). In some examples, detecting the sensor operator with the sensor includes detecting the sensor operator if the latch bolt is received within the latch recess. In one example, the sensor detects the sensor operator only if the panel is in the closed position and the latch is coupled with the latch fastener. Where the fenestration assembly includes more than one sash (e.g., panel), for instance, a first sash and a second sash, the first sensor detects the first sensor operator if both the first sash is in the closed position and the first latch is coupled with the first latch fastener. In a further example, the second sensor detects the second sensor operator if both the second sash is in the closed position and the second latch is coupled with the second latch fastener. In another example, the sensor detects the sensor operator if each of the first and second sashes are in the closed position and the latch is coupled with the latch fastener.
Optionally, the sensor is electrically coupled with a sash interface (e.g., panel interface). A frame interface is coupled with the fenestration frame. Detecting the sensor operator with the sensor includes engaging the sash interface with the frame interface to complete a circuit. In various examples, the respective sash interface is engaged with a respective frame interface when the sash is in the closed position. Accordingly, the sensor is communicatively coupled with the status monitoring assembly when the sash (e.g., a first panel, second panel, or both) are in the closed configuration.
At 1040, a secure configuration notification is provided if the sensor operator is detected by the sensor. For instance, providing the secure configuration notification includes, but is not limited to, providing a signal from the sensor, transmitting a notification from a wireless transceiver communicatively coupled to the sensor or the like. In one example, providing the secure configuration notification includes providing the secure configuration notification only if the sensor operator is detected by the sensor.
