Description

Window Status Sensor System

FIELD OF THE INVENTION

The present invention relates to a window status sensor system, an assembly comprising a window and a window status sensor and to a method of sensing the status of a window.

BACKGROUND TO THE INVENTION

Security systems often include sensors to detect the unauthorised opening of a window, for example, during a burglary. Such sensors are generally located on the edge of the window located distally from the pivot with a corresponding sensing device being mounted on the window frame. As the window is pivoted towards an open position, the sensor is activated and an alarm signal may be generated. Such an alarm signal generally consists of a loud audible alarm which provides an alert to the property owner (or surrounding inhabitants) and also acts to scare the intruder due to the awareness of the unauthorised act having been detected.

Such alarms can be trigger inadvertently and these audible alarms may no longer attract the attention of surrounding unconnected people. Accordingly, an intruder may now continue with the unauthorised access in the knowledge that the alarm may not attract the attention of any unconnected people. In addition, the property may be located in a remote position with few, if any, surrounding people.

Many people now simply assume that an alarm is a false alarm and will not necessarily act on the triggering of an alarm system. This may be particularly relevant if such an alarm system has previously been triggered with a false alarm situation.

Accordingly, such alarm systems must be very robust to prevent false alarms and/or the alarm signal must be transmitted to the responsible person or surveillance person. Such people may be located remote from the location and a transmission method will therefore be required.

In addition, these alarm systems for use with windows provide a simple check on whether the window is actually open or closed and no further information with regards to the status of the window is available.

Property owners may want to confirm the status of the property and, for example, may want to ensure that all the doors/windows are closed and/or locked, or the lights are off (or on, as required), the status of any appliances etc. Such a status check generally requires a user to individually check each item or appliance. This can be time consuming and laborious and also is impractical in many situations.

It is an aim of the present invention to overcome at least one problem associated with the prior art whether referred to herein or otherwise.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

The present invention provides a window status sensor system which may be of particular use with a casement window of a domestic property. The window status sensor system may cooperate with or may be integrated into a home automation system. In such a home automation system, a user may be able to monitor and/or control several items throughout the property. For example, a user may be able to monitor and/or control numerous domestic parameters such as the status of a light, the status of a domestic appliances, the condition/status of a smoke detector, the level of an oil tank etc. The home automation system may also be linked to the thermostat and may also be linked to cameras within or around the property.

Such a home automation system may be controlled by and monitored on a smartphone, tablet, remote PC etc. A typical casement window 10 comprises a window frame 12 and a pivotally mounted window sash 14, as shown in Figure 1 and Figure 2. The casement window 10 has hinges in order to pivotally mount the window sash 14 in the window frame 12. The hinges are configured to enable the window to pivot about a vertical axis such that the window sash 14 is retained in a vertical plane.

Accordingly, the window sash 14 is arranged to open outwardly from one side of the window frame 12. However, it will be appreciated that the window status sensor system could be used with other types and styles of windows.

The casement window 10 includes a locking mechanism in order to lock the window, i.e. to lock the window sash 14 to the window frame 12 in a closed position. The locking mechanism comprises a locking handle 16 which is coupled to a locking rod 18 and such a locking mechanism comprises an espagnolette locking device. The locking rod locates in a Eurogroove 28 provided along the outer edge of the window sash 14.

The locking handle 16 is pivotally mounted to the inside of the outer rail 26 of the window sash 14. The locking handle 16 is coupled to the locking rod 18 by a coupling mechanism such that the rotational movement of the locking handle 16 causes translational movement of the locking rod 18. The locking rod 18 is located on the outer edge of the outer rail 26 of the window sash 14 and the locking rod 18 is retained to slidably move up and down this outer edge.

The locking rod 18 has a number of locking elements comprising locking lugs 20 which are arranged to project outwardly from the locking rod 18. These locking lugs 20 may comprise locking bolts or locking pegs etc. The movement of the locking rod 18 thereby causes movement of these locking lugs 20 upwardly and downwardly relative to the window sash 14 and the window frame 12.

The locking mechanism further includes keeps 22 which are arranged to accept and retain the locking lugs 20 in the locked configuration. In particular, each keep 22 includes at least one locking slot 24 into which a locking lug 20 can be slidably moved. As mentioned above, this movement is caused through the action of the rotation of the locking handle 16 causing the translational movement of the locking rod 18.

When the casement window 10 is in a closed but unlocked position, the locking lugs 20 are disengaged with the locking slots 24 of a respective keep 22. In order to lock the window 10, the locking handle 16 is rotated and the locking rod 18 is slidably moved in order to move the locking lugs 20 into respective locking slots 24 within a keep 22. In this configuration, the window sash 14 is both closed and locked, i.e. a user could not simply push the locking handle 16 or window sash 14 in order to open the window 10. The casement window 10 may be provided with a key mechanism in order to actively lock the casement window 10 in this configuration. In particular, the locking handle 16 may have a key locking mechanism to prevent rotation of the handle 16 unless the key has unlocked this mechanism.

Prior art sensor systems are available to detect whether a window 10 is open or closed. However, unfortunately, many windows 10 may simply be closed without the locking mechanism having been correctly set. For example, a window sash 14 may simply be pushed to a closed position or may be closed by the action of wind such that the locking lugs 20 are not actually engaged in the locking slots 24.

Such windows 10 have the appearance (i.e. by a visual inspection or by a prior art simple sensor system) of being correctly shut but the window 10 could actually be opened by a user simply pushing on the window sash 14. Accordingly, such signals give a false representation of the protection offered by the status of the window.

The present invention provides a window status sensor system which provides positive feedback on the status of the actual locking mechanism and the position of the locking rod 18. In particular, the present invention provides a signal concerning the position of the locking rod 18 and the associated locking lugs 20.

Accordingly, a user will know that the window 10 is actually locked rather than being merely in a closed position.

The window status sensor system detects and monitors the actual position of the locking rod 18 rather than merely monitoring the position of the window sash 14 and/or the locking handle 16 etc. Accordingly, this feedback provides positive reassurance that the locking lugs 20 are actually in an engaged/locked position.

A first embodiment of a window status sensor system operates with a typical UK/European style espagnolette locking system on a casement window, as shown in Figure 1 to Figure 8. Such a casement window includes a Eurogroove within the window and this is utilised in the first embodiment of the present invention.

The window sash 14 is shown in an unlocked and open position in Figure 1 and Figure 2. The position and placement of the keeps 22 and locking lugs 20 can be clearly seen but the present invention is not limited to this particular arrangement.

The window sash 14 can be pivoted using the hinge arrangement to a simple closed (but unlocked) position, as shown in Figure 3 and Figure 4. In this position, the locking handle 16 is in a raised position and the locking lugs 20 are aligned with a mouth portion of a respective locking slot 24 provided on a keep 22.

As the locking handle 16 is rotated downwardly, the locking lugs 20 slidably move upwards into the locking slots 24, as shown in Figure 5 and Figure 6. In this position, the window sash 14 is positively engaged with and locked to the window frame 12 such that the window sash 14 cannot be pivotally moved about the hinges. As mentioned above, a further key locking mechanism can be used to further secure the window sash 14 in this position.

The window status sensor system comprises a sensor component and an actuator component which cooperate and register only in this locked position. As shown in Figures 7 and Figures 8, the sensor comprises a switch 30 and, specifically, a plunger type switch 30 which is only activated by a physical abutment and/or physical movement. The locking lug 20 provides the actuator in this arrangement.

In particular, an abutment surface 32 of the locking lug 20 is arranged to abut and subsequently press the plunger switch 30 in order to activate the sensor. This demonstrates that the espagnolette rod 18 is in a locked position.

A reversal of the movement of the espagnolette rod 18 will disengage the locking lug 20/32 from the sensor switch 30 and the sensor will thereby detect that the espagnolette rod 18 is in an unlocked position. Accordingly, the present invention does not detect false positives in which the position of the window sash 14 and/or locking handle 16 may indicate remotely that the window 10 was secure when in fact the window 10 may be unlocked.

The window status sensor system includes a transmitter in order to transmit the status of the switch 30 to a remote location. In particular, the transmitter is arranged to transmit the signal wirelessly into their home network utilising a Wi-Fi network. This then enables a user to be notified of a change in status of the window 10 or for a user to positively confirm the status of a window 10 using a mobile phone.

An alternative version of a casement window 10 is shown in Figure 9 to Figure 14.

This casement window 10 is typical of an espagnolette locking mechanism used in the US. It is noted that there is no Eurogroove in such a window. However, the present invention can be adapted for use with such a window. Again, this locking mechanism includes locking lugs 20 which are moved into engagement with a respective locking keep 22. The locking lugs 20 are moved into a locking position adjacent to a locking surface 42 provided by the keep 22. Such a locking surface 42 prevents the window sash from being simply moved to an open position prior to the unlocking movement of the locking lugs 20. This locking surface 42 may be provided by a single abutment face 42 rather than an enclosed locking slot as shown with the first embodiment of the present invention.

In this embodiment, the sensor again comprises a switch 30 which is activated by a physical contact caused by the movement of the espagnolette rod 18.

The sensor comprises a plunger type switch 30 located within a housing 34. The housing 34 is secured within the groove provided on the window sash 14. In particular, the housing is secured and located adjacent to a longitudinal end 36 of the espagnolette rod 18. Accordingly, in this version, the end face 36 of the espagnolette rod 18 acts as the actuator and is arranged to abut and press the switch 30 inwardly.

As shown in Figure 11 and Figure 12, in the unlocked position, the longitudinal end 36 of the espagnolette rod 18 is spaced apart or just touching the end of the sensor switch 30. When the window 10 is locked, the espagnolette rod 18 is raised such that the sensor switch 30 is pressed and this activates the sensor.

A further embodiment of a window status sensor system is shown in Figure 15 and Figure 16. In this embodiment, the window status sensor system detects the movement of the espagnolette rod 18 using a magnet 38 as the actuator and the sensor comprises a magnetic switch type device 40. As shown in Figure 1 5a and Figure 15b, in the unlocked position, the magnet 38 is spaced apart from a reed switch 40 such that the reed switch 40 will be in the default position (e.g. open).

However, as the espagnolette rod 18 is moved upwardly into a locked position, the reed switch 40 is moved into an aligned position with the magnet 38. In this locked position, the magnet 38 will activate the reed switch 40 such that a signal can be transmitted to confirm that the window 10 is in the locked position.

As mentioned above, the window status sensor system comprises transmission means in order to communicate the status of the window 10 through the local Wi-Fi network. This signal may be communicated to a cloud server and then subsequently to the smartphone of the user. Each sensor is individually coded such that a software application (app) on the smartphone will be able to correctly identify the individual window 10, for example bedroom window. Prior to installation or even after installation, the sensor may be connected to a PC using a USB connection in order to set up or reconfigure the sensor.

The sensor unit installed on the window comprises a battery and this battery may be inert until activated.

Overall, the present invention provides a window status sensor system which is solely operated by the movement of the espagnolette rod 18 and not by any other component. This reduces the risk of obtaining a false positive in which a user may inadvertently believe that a window 10 was in the locked position when in fact the actual locking mechanism had not been correctly engaged.

The window status sensor system can be fitted retrospectively. For example, the window status sensor system may be incorporated into a keep 22 which may resemble a standard espagnolette keep. Such a keep 22 could then be used to replace an existing keep in order to convert the casement window 10 into a fully monitored casement window 10. Alternatively, the system could be retrospectively fitted by using the embodiment shown in Figures 9 to 14 in which the housing unit 34 is simply fixed within the groove 28 adjacent to the end of the espagnolette rod 18 in order to provideafully monitored casement window 10.
