Description

STATE OF THE ART

The present invention is in the field of building technology and there in the field of the automatic monitoring of building openings, in particular windows and doors, in particular those that can be brought into a tilted position, and relates to a method and a device according to the respective preamble of the independent claims.

The European patent application EP 1 860 624 A1 discloses a monitoring system for the opening state of windows or doors, which recognizes the states “closed” and “open or tilted” by means of an RFID system which is attached between the frame and the door or window sash.

The German patent specification DE 10 2016 107 868 B3 develops this state of the art. It discloses a system for recognizing the opening state of a window or a door, which can sense the states “closed”, “swiveled open” and “tilted open” by means of a three-dimensionally sensing Hall sensor and can process them accordingly.

Disadvantageously, such systems or comparable other systems that can sense the same conditions are not yet reliable enough for the complex situations that arise depending on the construction of the building to serve as reliable sources of information for the true opening state of a window or door to be able to. Because under certain everyday circumstances, despite their extensive technical sensors and evaluation logic, they actually provide incorrect information or even misleading information, as has now surprisingly been recognized. If, however, such incorrect information is passed on to the corresponding control systems available in the building, such as security systems against burglary or air conditioning, ventilation or heating systems, the resulting control measures are consequently mostly incorrect. In the case of a security system against burglary, this means that false alarms can be triggered or that the security system “thinks” that a corresponding window is closed, but in reality it is open. Thus, the security system does not comply with what it should do according to the prospectus. In the case of a ventilation system, for example, it is falsely recognized that a window should be in a folded position. The ventilation system “thinks” that there is a sufficient supply of fresh air from outside and, for example, enables the operation of an extractor hood if a stove is in operation at the same time. In this case, however, the window leaf is actually in contact with the frame and there is no fresh air supply. The extractor hood then sucks the exhaust gas containing carbon monoxide from the stove into the room air. As a result, the people in the room are acutely life-threatening.

In the German utility model DE 20 2005 006 796 U1 a device for monitoring the closed position of a handle for a closing fitting of a window sash and for its inclination is disclosed. This embodiment has the disadvantage that retrofitting an existing system creates a lot of effort, with the actually usable components of the handle mechanics having to be replaced with the gearbox and the handle chassis. In addition, the chassis of the handle would be larger or thicker if the sensors were integrated and would therefore presumably be immediately recognized by an intruder from the outside as an "alarm window".

In the US patent U.S. 5,226,256 the sensors for detecting the leaf position are not installed in the same place as the sensors for detecting the closed fitting position. In addition, the evaluation unit for the signals from the sensors is not attached to the window itself but in the immediate vicinity. When retrofitting a window, this distributed positioning disadvantageously implies a lot of effort and a separate component for the evaluation unit, which must be mounted separately. Better to avoid that.

In the German patent application DE 101 61 761 A1 a device for monitoring the inclination and the opening state of a window sash is disclosed. Disadvantageously, the closed position of the locking pin or the position of the handle is not detected.

The international patent application WO 2012/054942 A1 discloses a device for monitoring the open state and the closed position of a window sash. However, the device shown there is disadvantageously labor-intensive and expensive when new windows are manufactured and when they are retrofitted, because the sensors are distributed over the window frames and window sashes. In addition, it is disadvantageous that the device cannot recognize all the opening states of a tiltable or pivotable window that are relevant for everyday use.

In the German patent application DE 10 2004 018 064 A1 a monitoring device for remote monitoring of the closed position of a window handle is disclosed, in which sensors detect the position of a shift gate which clearly defines the handle position. Sensor signals are transmitted wirelessly to a central monitoring unit. The built-in technology for remote monitoring from the outside is disadvantageous because the housing on the handle base is significantly thicker than usual. Thus, burglars would be warned. For retrofitting, complete handle sets would also have to be replaced, which is relatively expensive.

The German patent application DE 198 15 766 A1 discloses a mechanical window lock in addition to the normal locking mechanism, which sits in a housing which is attached to the outside or inside of the frame of a window and which locks the window sash against the frame. An electric motor drives the bolt to lock it. Disadvantageously, the system is not integrated in the frame and can be seen from the outside through the glass pane. Burglars are thus also forewarned.

The object of the present invention is therefore to improve the sensor system for checking the opening state of windows or doors and to make them simpler and more reliable, in particular with regard to installation on the window or door.

ADVANTAGES OF THE INVENTION

The subject matter according to the invention with the features of the respective subsidiary claims solves this problem.

The respective subclaims contain advantageous developments and improvements of the respective subject matter of the invention.

According to a first aspect of the present invention, a method is disclosed that is implemented in a microcontroller, for example, for detecting the open state of a building opening that has a movable closing surface that is in an open position and / or in a tilted position relative to a stop frame - often as Outer frame referred to - can be brought for the closing surface, in particular a window or a door with a window sash or a door leaf as the closing surface, with the steps: receiving a first signal from a first sensor that indicates the inclination of the closing surface or a distance from the closing surface to the Stop frame sensed and encoded, receiving a second signal from a second sensor that senses and encodes the handle position or the fitting position, characterized by the steps of: evaluating the combinations of the codings of the first and second signals, generating an evaluation signal that indicates the addition “unlocked, but ajar” and / or “tilted position, but ajar” would be coded.

The handle position should be understood as the position in which the handle located on a window leaf or on a door leaf is located. The usual positions are "locked", "unlocked" and "folded position", there is also an optional "mini-folded position" in which the folding angle is extremely small in order to allow only a small amount of air to be exchanged.

These three or four handle positions clearly correspond to corresponding positions of one or more latches in the fitting and result in a corresponding “fitting position” in the above sense. The handle can also use a corresponding mechanism to operate several fittings, such as a fitting in the upper area and a fitting in the lower area of the vertical stop edge of a door leaf, and a fitting on its upper, horizontal stop edge, and a fitting on the lower stop edge.

The invention is based on the knowledge that the above-mentioned disadvantages of the prior art, such as the lack of reliability of the sensed signals in terms of suitability for everyday use, can be eliminated by recognizing and specifically recognizing signal combinations that have not previously been evaluated in the prior art as being relevant for reliability evaluates.

• Der eine Sensor liefert ein Signal, das auf ein unverriegeltes Fenster- oder Türblatt schließen lässt, und der andere Sensor liefert ein Signal, das darauf schließen lässt, dass das Fenster- oder Türblatt am Blendrahmen anliegt. Diese Kombination führt zu einem neuen Zustand „unverriegelt angelehnt“. Der andere Sensor liefert ein Signal, das auf ein in Kippstellung befindliches Fenster- oder Türblatt schließen lässt, und der andere Sensor liefert ein Signal, das darauf schließen lässt, dass das Fenster- oder Türblatt am Blendrahmen anliegt, wenn der Abstand je nach der Position des Sensors nah oder entfernt zur Achse entsprechen gering ist. Diese Kombination führt zu einem neuen Zustand „in Kippstellung angelehnt“.

These new combinations are:

• One sensor supplies a signal that indicates an unlocked window or door leaf, and the other sensor supplies a signal that indicates that the window or door leaf is in contact with the frame. This combination leads to a new "unlocked ajar" state. The other sensor supplies a signal that indicates that the window or door leaf is in the tilted position, and the other sensor supplies a signal that indicates that the window or door leaf is in contact with the frame, if the distance depends on the position of the sensor close to or away from the axis is low. This combination leads to a new state "leaning in tilted position".

The method according to the invention for detecting ajar window and door leaf status can be used in combination with a sensor for determining the handle position or with a sensor for determining the fitting position on the one hand, called the "second sensor" in the claims, and on the other hand a sensor for detecting the status of the window sash, called the “first sensor” in the claims. Both sensor signals are preferably processed in a single evaluation unit. With this method according to the invention it is thus possible to clearly distinguish whether a window or a door is actually ajar with the handle in the open position or ajar with the handle in the tilted position.

• Wenn ein Griff auf der Stellung „gekippt“ ausgewertet wird und das Fenster jedoch nicht gekippt, sondern angelehnt ist, gilt es nicht mehr wie im Stand der Technik als ein gekipptes Fenster, durch welches hindurch ein Luftaustausch stattfinden könnte. Es findet erfindungsgemäß also keine falsche Zustandserkennung mehr statt.

The following advantages result:

• If a handle is evaluated in the "tilted" position and the window is not tilted, but ajar, it is no longer considered a tilted window, as in the prior art, through which an exchange of air could take place. According to the invention, there is no longer any incorrect status detection.

Since there are safety-relevant regulations, such as the regulation to be checked by the chimney sweep, that in the case of an extractor hood with exhaust air to the outside and the existence of a fireplace in the same or in the adjoining room, that the extractor hood can only be switched on if a window is correctly tilted, i.e. open, so that a sufficient external air supply is guaranteed, basically only the strict application of the teaching according to the invention enables compliance with this rule.

A prior-art sensor would provide an evaluation unit for compliance with this aforementioned safety-related regulation for switching the extractor hood with an incorrect state, e.g. for a tilted window, if the user only moves the handle to the tilting position, but deliberately leaves the window ajar . The external air supply required for safety would then not take place here. Therefore, systems from the state of the art have a very critical weak point, since it is about avoiding life-threatening circumstances. According to the invention, this weak point no longer exists.

If a handle is set to the unlocked, open position and it is assumed, as systems from the prior art do, that the window is open even when it is ajar, this would have fatal consequences or disadvantages if the sensor data were used for evaluation who would use ventilation intervals. According to the system evaluation according to the state of the art, one would assume that, even with the windows or doors ajar, a sufficient external air supply, which is important for avoiding mold, has been received for the period until the window or door is properly closed. Since in this example from the prior art an incorrect state was determined by the sensor, the ventilation data that are important for avoiding mold formation would be incorrect. Such disadvantages are clearly avoided according to the invention because an additional control takes place by querying the corresponding sensor as to whether the window sash is in contact with the frame.

If systems according to the invention comprising sensors and evaluation unit are used in alarm systems instead of those from the prior art, the user no longer has the disadvantage from the prior art that false alarms have to be laboriously avoided. Because if the alarm monitoring is activated, the user in the prior art cannot change the window from the closed state - without having previously deactivated the alarm monitoring - to the tilted state, because in the prior art he has to open the window from "closed" To change "tilted", the handle can always move from the position for "closed" via "open / open" to "tilted". According to the invention, there is thus a significant increase in the ease of use and false alarms for such a reason are reliably avoided.

If the evaluation unit and one of the two sensors are integrated in an elongated structural unit, the geometric format of which matches the profile of the sash or the window frame, there is a relatively high degree of flexibility with regard to the selection of the mounting locations for the structural unit and the remaining sensor.

If the evaluation unit and both sensors are provided in a single structural unit of this type, the advantage of simple installation and the advantage of robust operation of the sensors results, especially when installed on the lower horizontal edge of the building opening. The structural unit can be provided with a tread-resistant housing and attached either to the sash part or to the frame of the window or door.

If a transmitter component of the sensor for sensing the fitting position is provided directly on one face of the structural unit, and the structural unit is set up to be able to be mounted on the face directly next to a locking fitting into which the locking pin engages and in which it is moved back and forth , and the transducer component physically or its sensing effect extends into the lock fitting, there is the advantage of an integrated component that does not have any interfaces that would otherwise have to be taken into account during assembly. The sensor for sensing the position of the fitting pin can also be implemented in other ways, for example by microswitches that are switched by the movement of the fitting pin, or by three reed contacts that are arranged along the rail in the locking fitting part within which the pin moves. Such a compact fitting part with built-in, self-sufficient window sensors can be particularly suitable for integration into the corresponding Window or door parts are advantageously used directly in their factory production.

If the first and the second signal are transmitted to an evaluation unit provided externally from the window or externally from the door, and the evaluation unit generates the evaluation signal, then an exact differentiation of the opening states with more in-depth, more easily updateable, software-based, here called “primary” Evaluation possible, which enables corresponding individual control measures to be carried out automatically or manually by corresponding dedicated systems for security or air conditioning, etc. In addition, the way is paved for a so-called secondary evaluation, which can collectively process the data of the opening status of several windows / doors and evaluate them "secondary" with a view of the entire building. A building management system, or a specialized, computer-aided system of building technology, such as a security system or an air conditioning system, etc., can then, when it receives these primary evaluation signals or a secondary evaluation, take appropriate measures of different priority that can be better adapted to the building in comparison to uncoordinated individual measures from corresponding primary individual evaluations. For example, for a single-family house, as a secondary evaluation of four recognized “ajar-open” windows on the ground floor, the ventilation can be controlled to “medium”, and the lowering of the blinds of all windows on the ground floor of the building can be carried out automatically, but only when the front door is closed, and it can thus be seen that there is no longer anyone in the building.

If the fitting position is sensed by the position of a fitting pin provided on a window or door leaf in a matching locking fitting part provided on the stop frame, then a way has been found that is suitable for a large number of modern locking fittings for doors or windows.

Usually the fitting pin is designed as a mushroom head and is present in the window or door leaf at its stop edge, and is moved by the handle along the stop edge, whereby when it hits the frame (stop frame), it is guided in the rail of a corresponding fitting part that in turn is attached to the stop frame. Thus, the leaf is attached to the frame in the closed position or released depending on the position of the handle.

According to the invention, the fitting position in windows or doors without a motor drive of the tilting movement is sensed via the respective position of the fitting pin in the rail of the counter fitting. If the fitting position of windows with a motorized tilting movement is sensed, for example, with a stepper motor via a clearly assignable position of drive means such as gear wheels or a drive belt, etc., which are provided for a motorized movement of the fitting pin in the locking fitting, then there is an alternative shown for the positioning of the sensor for the detection of the fogging position. If a linear motor with a fixed coupling of the rotor to the fitting pin is used, the fitting position results from the relative position of the rotor relative to the stator. Depending on the design of the control of the linear motor with or without a programmed driver interface, a separate sensor can even be dispensed with.

If the evaluation signal is transmitted to a building management system by cable or by radio, such as to a security system for building monitoring, or to an air conditioning system, or to a heating system or a cooling system of the building, to initiate respective, system-specific and evaluation signal-specific control measures, then The result is the advantage that not only a presumably unintentional opening state of a window or door is recognized as a suspected error, but that this error can also be corrected within certain limits by the respective system taking smart countermeasures to avoid the error possibly caused Correct wrong measures again. This makes the overall "building management" system more robust.

If the evaluation signal is sent to a receiving unit of a logic controller that is set up to control a drive means for closing or opening a window or a door, in particular for controlling a drive means of that window or that door, the opening state of which was described by the evaluation signal, then it can be done immediately can be counteracted locally, for example by actuating the motor drive to tilt the sash, whereby the window sash is brought into a really physically present tilted position that no longer corresponds to the previous "ajar" state.

Such a measure is advisable, for example, if a resident wants to switch on their extractor hood, but the fireplace is burning, and therefore tilts a nearby window. If it is now too cold in winter, he may be tempted to lean against the window again and leave the handle in the tilted position. An automatic opening of a window in its folded position now prevents acute in the room Risk of poisoning from carbon dioxide or carbon monoxide from the flue gas of the chimney.

DESCRIPTION OF THE EXEMPLARY EMBODIMENTS

In the figures, the same reference symbols denote the same or functionally identical components.

First embodiment, tiltable and swiveling window with right stop.

• Ein erster Sensor 10, der den Abstand oder den Spalt zwischen Fensterflügel 30 und Blendrahmen 40 sensiert, ist am Fensterflügel angebracht. Im Folgenden wird er wegen leichterer Verständlichkeit „Spaltsensor“ genannt. Ein zweiter Sensor 12, der die Verriegelungssituation an einem ebenfalls am Flügel vorhandenen Beschlagteil erkennt, ist in unmittelbarer Nähe eines durch eine entsprechende Griffbewegung bewegbaren Beschlagzapfens 22 ebenfalls am Fensterflügel angebracht. Im Folgenden wird er wegen leichterer Verständlichkeit „Griffstellungs- oder Beschlagstellungssensor“ genannt. Eine Auswerteeinheit 14 empfängt Signale der beiden Sensoren 10 und 12 und wertet erfindungsgemäß zwei neue Signalkombinationen besonders aus. Sie erzeugt dann entsprechende Signale, die an den Benutzer unmittelbar in einer geeigneten Weise ausgegeben werden oder an weitere Systeme gesendet werden, die im weiteren Sinne dem Gebäudemanagement dienen, etwa Sicherheitssysteme oder Klimatisierungs-, Heizungs- oder Lüftungs- oder Kühlsysteme.

With common reference to 1 , 2 , and 3A , 3B :

• A first sensor 10 that is the distance or gap between window sashes 30th and frame 40 sensed, is attached to the window sash. In the following it is referred to as the “gap sensor” to make it easier to understand. A second sensor 12th , which recognizes the locking situation on a fitting part also present on the sash, is in the immediate vicinity of a fitting pin that can be moved by a corresponding handle movement 22nd also attached to the window sash. In the following it is referred to as the “grip position sensor or fitting position sensor” to make it easier to understand. An evaluation unit 14th receives signals from the two sensors 10 and 12th and according to the invention evaluates two new signal combinations in particular. It then generates appropriate signals that are output directly to the user in a suitable manner or are sent to other systems that serve building management in the broader sense, such as security systems or air conditioning, heating or ventilation or cooling systems.

These systems interpret this signal generated according to the invention against the background of their own complex of knowledge, expand the meaning specifically depending on the function, for example to "Sash is unlocked, window can be opened as wide as possible, high risk of break-ins, potentially full air exchange possible, window can open uncontrolled when drafts and hitting ... ”and can issue appropriate warnings to the user if they can process this new signal through an upgrade. An air conditioning system can intervene in a controlling manner in order to manage the ventilation or heating or cooling according to the real ventilation conditions.

The window sensor of the 3 until 6th is mounted in the lower area of the window on the horizontal edge between the sash and the frame. This has the advantage that all window states including the two new states “in tilted position ajar” and “unlocked / open ajar” can be determined very reliably by means of two sensors and can thus be clearly differentiated by the evaluation unit.

3A shows a schematic top view representation of a system according to the invention comprising two sensors and an evaluation unit in an installation situation between a window sash and a frame (stop frame) of a pivotable and tiltable window in a position in the state “fitting pin in tilted position and ajar”.

3B shows a schematic cross-sectional representation of a system according to the invention from 3A .

For example, a potentiometer is used for the “gap sensor”. A pestle 11 of the sensor that is not completely shown 10 scans the distance from the sash to the frame and changes the resistance of a potentiometer with a slider when it is extended and retracted. The evaluation unit thus receives gradually differentiable information from this sensor about how far the sash protrudes from the frame. Different areas of the resistance are assigned to different signals from the sensor.

A potentiometer can also be used as a second sensor, which serves as a "handle position or fitting position sensor". When the sash is in contact with the frame, this handle position or fitting position sensor supplies the evaluation unit with the exact handle or fitting position of the pin. In this case, the pin of the locking part on the window or door sash is shown on the potentiometer as shown in the drawings 13th of the sensor. An exact determination of the position of the fitting pin can thus be recognized by the changed resistance, and a corresponding signal can be given to the evaluation unit.

The wing 30th lies on the frame 40 at. The gap sensor 10 with pestle 11 detects this because it is in its most depressed position. It generates a signal that is coded with the meaning “The window sash is on the frame, there is no significant air gap” and accordingly from the one on the window sash in the immediate vicinity of the two sensors 10 , 12th attached evaluation unit 14th is received and processed.

The fitting pin 22nd of the fitting part is in a left outer position in the drawing, which in the installation situation often corresponds to the lower position in which the fitting and the handle are in the tilted position, and accordingly the wing can move within certain limits around its horizontal hinge axis in its tilting range . The grip position or fogging position sensor 13th detects this position of the fitting pin 22nd because he is along the contact surface of the potentiometer 13th dragged along by the fitting position sensor, and generates a signal with the meaning "fitting pin is in the tilted position, window could be tilted, if not on the frame, certain risk of break-in" is coded and accordingly by the evaluation unit 14th is received and processed.

In the exemplary embodiment shown, the signals are transmitted from the sensors to the evaluation unit by cable. The evaluation unit is designed as a microcontroller component with an integrated, long-life power supply through two button cells. It evaluates the signals according to the invention and, depending on the combination of the signals from the sensors, generates a specific signal that it can send to an alarm system in the house or to an air conditioning system, as in FIG 2 shown.

4A shows a schematic plan view of a system according to the invention comprising two sensors and an evaluation unit in the installation situation according to FIG 3A and 3B , in a position in the state "Hinge pin in the tilted position and open in the sense of" not ajar "", i.e. in the normal tilted position normally intended by the user, which can be seen in the drawing by the inclination of the sash profile in relation to the frame. This changes compared to 3A not much because of the locking pin 22nd is not moved translationally in the fitting direction, but is only tilted slightly in the same position. The signal stays the same as that in 3A .

4B shows the schematic cross-sectional representation of a system according to the invention 4A . The plunger 11 of the gap sensor is compared to 3B moved out a little further and can therefore change its state in 3B differentiate and generate a correspondingly differentiated signal.

5A illustrates the situation in which the hinge pin 22nd is located in a central position, so the window sash is unlocked and can be freely pivoted about its vertical axis. sensor 12th generates a corresponding signal "Window is unlocked, there is a high risk of break-ins".

the end 5B it can be seen that the window sash is unusually in contact with the frame. At a cursory glance in this state, a user does not notice that one only has to press lightly against the window from the outside in order to open it completely and to be able to enter the house. sensor 10 sensed about the fully retracted ram 11 that there is no gap between the sash and the frame and sends a corresponding signal "Sash is leaning against the frame" to the evaluation unit 14th .

The evaluation unit programmed according to the invention 14th recognizes the new combination of these two signals and their significance for alarm systems and air conditioning systems.

This state “fitting pin unlocked open and window sash ajar” is transmitted wirelessly to the alarm system as a new window state according to the invention 16 and to the air conditioning system 18th .

6A shows a schematic plan view of a system according to the invention comprising two sensors and an evaluation unit in an installation situation in the installation situation according to FIG 3A and 3B , in a position in the state "Fitting pin unlocked open and not ajar". The fogging sensor 12th does not register any contact with the fitting pin 22nd .

6B a schematic cross-sectional representation of a system according to the invention 6A . The plunger 11 of the distance sensor 10 has moved out as far as possible. The sensor therefore generates a signal “The window sash is open, the free part of the window is not in contact with the frame.

Both signals are sent to the evaluation unit, which for its part, as known in the prior art, forwards them to alarm systems or an air conditioning system.

In 7th the control flow of the logic programmed in the evaluation unit is shown, but limited to the aspects newly added by the present invention. The steps shown are programmed and embedded in an existing control flow in the state of the art.

In the steps 110 and 120 receives the evaluation unit 14th the signals from the two sensors 10 and 12th that provide information about the opening status of a window.

In step 130 According to the invention, the evaluation unit processes signal pairs from signals from the sensor 10 and the sensor 12th that are received essentially at “the same point in time”, or at most a maximum predefined blocking time of 0.1 seconds, for example, are received one after the other.

• „Signal 1 von Sensor 10 bedeutet „Fenster lehnt an Rahmen an“ und
• „Signal 2 von Sensor 12 bedeutet „Fenster ist unverriegelt, offen“
• Dies ist die eine von zwei Signalkombinationen, die erfindungsgemäß auf einen entsprechend neuen Öffnungszustand des Fensters hinweisen, der eine entsprechende Sonderbehandlung durch ein Alarmsystem oder ein Klimatisierungssystem erfordert oder empfehlenswert erscheinen lässt.

The logic programmed according to the invention decodes the incoming signals and evaluates them according to an identification code which precisely encodes their meaning for the building services. In particular, according to the invention, the logic monitors certain events that are defined by the "simultaneous" arrival of the following signals in the above sense:

• "Signal 1 from sensor 10 means "window leans against frame" and
• "Signal 2 from sensor 12th means "window is unlocked, open"
• This is one of two signal combinations which, according to the invention, indicate a correspondingly new opening state of the window, which requires appropriate special treatment by an alarm system or an air conditioning system or makes it appear advisable.

• „Signal 1 von Sensor 10 bedeutet „Fenster lehnt an Rahmen an“ und
• „Signal 2 von Sensor 12 bedeutet „Fenster ist laut Beschlagsensor in Kippstellung“
• Dies ist die zweite der beiden Signalkombinationen, die erfindungsgemäß auf einen entsprechend neuen Öffnungszustand des Fensters hinweisen, der eine entsprechende Sonderbehandlung durch ein Alarmsystem oder ein Klimatisierungssystem erfordert oder empfehlenswert erscheinen lässt.

Or:

• "Signal 1 from sensor 10 means "window leans against frame" and
• "Signal 2 from sensor 12th means "According to the condensation sensor, the window is in the tilt position"
• This is the second of the two signal combinations which, according to the invention, indicate a correspondingly new opening state of the window, which requires appropriate special treatment by an alarm system or an air conditioning system or makes it appear advisable.

These two new signal combinations are recognized by the evaluation unit according to the invention and sent to the alarm system of the building, possibly with a code that indicates the position of the window, so that the user immediately knows where to intervene manually to clear the situation.

The other signal combinations are recognized, as is relevant, and sent to the systems mentioned.

Then the logic goes back to step 110 and repeat the process.

The above-described logic according to the invention can be implemented en bloc or also woven into existing logic processes in sections.

• Montage der beiden Sensoren sichtbar auf der Fensterseite zum Innenraum hin: Dann würde man die Vorrichtung allerdings sehen, was nicht nur ein optischer, sondern auch aus Sicherheitsaspekten ein Nachteil sein kann, da ein Einbrecher die Überwachungstechnik sofort erkennen kann.

Variants according to the invention of this exemplary embodiment with other mounting positions are described below:

• Installation of the two sensors visible on the window side facing the interior: Then you would see the device, which can be a disadvantage not only from an optical point of view, but also from a security point of view, since an intruder can immediately recognize the surveillance technology.

• Man hat bei einem gekippten Fenster in nachteilhafter Weise keine Anbindung vom Fensterrahmen zum Fensterflügel und muss, um die Fensterstellung „offen“ und „gekippt“ unterscheiden zu können, einen weiteren Sensor einsetzen. Oder die Auswerteeinheit muss sich über eine separate Logik permanent merken, von welchem Fensterzustand sich das Fenster gerade zum nächsten Zustand bewegt:

Installation of the two sensors visible on the window side facing the interior in the upper area of the window:

• With a tilted window, there is disadvantageously no connection from the window frame to the window sash and an additional sensor must be used in order to be able to differentiate between the “open” and “tilted” window positions. Or the evaluation unit must permanently remember via a separate logic from which window state the window is currently moving to the next state:

For example, if the fitting pin comes from the “closed” handle position and the sensor for detecting the handle position is no longer activated after the window has changed, the logic can assume that the window is “open”. If, on the other hand, the fitting pin briefly moves from the handle position “too” to the handle position for “tilted”, and then the sensor for the fitting evaluation is no longer actuated, the logic can evaluate that the window is tilted. The disadvantage of this example, however, is a lower reliability and robustness, and the evaluation unit has to find its way back into the correct order after each restart.

Another variant of the device is that one for the sensor 10 which evaluates the condition of whether the sash is in contact with the frame or is tilted, other sensors such as inclination sensors, distance sensors or other sensors can be used in the window seal, in the fitting scissors, in the corner hinge of the fitting or in the window profile. This status evaluation can then be carried out with the status evaluation from the sensor 12th , which is used to recognize the grip position and / or. the fitting is used, can be combined. Then the new window states "Leaning - fitting in open position" and "Leaning - fitting in tilted position" can also be transmitted to other systems as a signal for further processing in an evaluation unit.

The signals generated according to the invention for recognizing the problematic opening states can be used in a large number of building technology systems. The following are mentioned as examples: Alarm systems, so-called “smart home” systems with various automated functions, gateways, building management systems, and systems for controlling individual components of a building such as radio roller shutter drives.

The method according to the invention for evaluating the signals with the newly found opening states can be implemented with a large number of sensors.

• Ein Ausführungsbeispiel wie oben im Zusammenhang mit den Zeichnungen beschrieben, wobei jedoch als zweiter Sensor, der „Griffstellungs- oder Beschlagstellungssensor“ ein System vorgesehen ist, das drei Reedkontakte zur Positionserkennung des Beschlagzapfens 22, entsprechend den Griffstellungen Griff auf, Griff zu, Griff gekippt, enthält, wobei der Beschlagzapfen 22 ein Permanentmagnet ist.

Further exemplary embodiments of the invention are explained below for sensor arrangements without explicit drawings:

• An exemplary embodiment as described above in connection with the drawings, however, a system is provided as the second sensor, the “handle position or fitting position sensor”, which has three reed contacts for detecting the position of the fitting pin 22nd , according to the handle positions handle open, handle closed, handle tilted, contains, the fitting pin 22nd is a permanent magnet.

If you also position this sensor version in the lower horizontal area between the frame and the sash, you can do without the other sensor, the "gap sensor", provided that you would only value the evaluation of the new status "unlocked / open and ajar" because In this mounting position, the gap sensor is only required for the further new state “leaning against in tilted position”.

A sensor arrangement as described above in connection with the drawings, but an inclination sensor serves as the gap sensor, and the installation position of the window sensor remains in the horizontal between frame and sash, but the window sensor is attached under the sash and not on the frame next to a lock fitting. The "handle position or fitting position sensor" then also detects the pin. As the inclination changes in this installation situation, the inclination sensor detects whether the sash is parallel to the outer frame or at an angle (tilted) to the outer frame. This sensor can also determine all states, including the two new states, but has the disadvantage that, when used in a safety system, it cannot detect the levering out as reliably as with the tappet above in connection with the figures.

Likewise, in this example with an inclination sensor, the mounting position could also be changed further, for example in the vertical laterally between the window sash and the frame. Here, however, has the "handle position or Fog position sensor ”has the disadvantage that the pin is not in contact in all window positions, but only when the window is closed. You can now implement another logic that remembers where the pin must have been moved. However, this would not result in the reliability normally required for application purposes of the window sensor. The same applies if the sensor were to be placed in the horizontal position in the upper area of the window. In addition, the sensor would be accessible in the tilted state and would make sabotage easier for burglars.

In this exemplary embodiment, the "handle position or fitting position sensor" is located in a window handle that can be swiveled as usual. Four reed contacts placed around the inner pin, which forms the axis of rotation of the handle, can determine the exact position of the handle, whether the handle is up, right, down or left. In this example, the second sensor, the "gap sensor", would be, for example, another reed contact or a microswitch, which, in addition to the position of the handle, evaluates whether the sash is in contact with the frame or not. If a cable connection is provided from the sensors to the evaluation unit, it makes sense to place the gap sensor directly next to the handle position or fitting position sensor. However, compared to the above examples, this has the disadvantage that there is no contact between the frame and sash when the window is tilted and the lack of contact in an alarm system could not be easily secured. Now a third sensor would have to be added, which can detect e.g. acceleration and thus the attempt to open the door. This measure, however, would not guarantee the reliability as in the case mentioned above . If, on the other hand, the second gap sensor is placed at the bottom of the window sash and this data is transmitted, for example using energy-saving radio technology such as the "Bluetooth Low Energy" radio technology, this arrangement enables reliable detection of the two new window states as described above in connection with Embodiment illustrated in the figures

Furthermore, the energy for wireless signal transmission could be obtained from the movement of the gap sensor or handle position or fitting position sensor, or from the movement of the window or door leaf itself. By using suitable energy storage devices, this device could work electrically, but without batteries, but only with self-charging accumulators. A solar cell as an energy generator would also be possible.

Although the present invention has been described above on the basis of a preferred exemplary embodiment, it is not restricted thereto, but rather can be modified in many ways.

• Fenstergriff auf „Gekippt-Stellung“ + „Reedkontakt durch Magnet betätigt“ ermöglicht die Erkennung des Zustand „Angelehnt, Beschlag in Kippstellung“, wie er vermutlich vom Benutzer nicht beabsichtigt ist.

The present invention can also be implemented with the wireless window handles available in the prior art, for example at https://www.enocean-alliance.org/de/product/hoppe secusignal-funk-window handle /). The wireless window handle only monitors the handle position for "closed", "open" and "tilted". If you now, for example, couple a reed contact with the wireless window handle and attach a magnet to the window frame, this additional sensor gives you the option of recognizing whether the window sash is touching the frame. The method according to the invention for detecting the states “Leaning, fitting in tilted position” and “Leaning, fitting in open position” can also be implemented with these two sensors, since the grip position can be evaluated and the additional sensor can simultaneously determine whether the Window sash rests against the window frame as follows:

• Window handle on "Tilted position" + "Reed contact actuated by magnet" enables the detection of the state "Leaned, fitting in tilted position", which is probably not intended by the user.

Only the window handle on "Tilted position" + "Reed contact not actuated by magnet" enables the detection of the "Tilted" state, as it is probably intended by the user.

Window handle on "open position" + "reed contact actuated by magnet" enables detection of the state "ajar, fitting in open position", which is probably not intended by the user.

Only the window handle on "open position" + "reed contact not actuated by magnet" enables the "open" state to be recognized, as is probably intended by the user.

1. 1. Diese Vorrichtung eignet sich nicht, wenn man auch gekippte Fenster durch eine Alarmanlage auf ein mögliches Aufgehebelt-Werden hin überwachen möchte, da in diesem Fall nur der Griff auf der Stellung für „Gekippt“ die Daten für den Zustand, dass das Fenster gekippt sei liefert. Es müsste, noch eine weitere Anbindung vom Fensterflügel zum Fensterrahmen geschaffen werden, um auch bei gekippter Griffstellung zu überwachen, ob der Flügel wirklich am Rahmen anliegt.
2. 2. Optisch würde diese Lösung nicht wie das erste Ausführungsbeispiel versteckt im Fensterrahmen platziert sein. Dies kann auch weitere Sicherheitsrisiken z.B. im Hinblick auf Sabotage mit sich bringen.

The disadvantages of this device variant compared to the above based on the 3 until 6th illustrated embodiment are the following:

1. 1. This device is not suitable if you want to monitor tilted windows by an alarm system for possible being pried open, since in this case only the handle on the position for "tilted" the data for the state that the window is tilted be delivers. Another connection would have to be created from the window sash to the window frame in order to monitor whether the sash is really in contact with the frame, even when the handle is tilted.
2. 2. Visually, this solution would not be hidden in the window frame like the first embodiment. This can also entail further security risks, for example with regard to sabotage.

• In Auswerte- und/oder Analysesystemen für das Energiemanagement zu der Ermittlung von Lüftungsintervallen, in Lüftungssteuerungen, in smarthome-Systemen.

The method according to the invention can be used in many building management systems:

• In evaluation and / or analysis systems for energy management to determine ventilation intervals, in ventilation controls, in smarthome systems.

• Aktoren können mit direkt eingelernten Fenstersensoren folgende Schaltungen automatisieren:
  • Bei einer Lüftungsanlage wird der Strom automatisch abgeschaltet, wenn der Zustand „OFFEN“ oder „GEKIPPT“ vorliegt. Wenn der Zustand „ZU“, „unverriegelt, aber angelehnt“ und/ oder „Kippstellung, aber angelehnt“ vorliegt, wird der Schaltausgang eingeschaltet.

Using radio sockets and actuators for systems that switch electricity:

• Actuators can automate the following circuits with directly taught-in window sensors:
  • In the case of a ventilation system, the power is automatically switched off when the status is "OPEN" or "TILTED". If the status "CLOSED", "unlocked, but ajar" and / or "Tilt position, but ajar" is present, the switching output is switched on.

In the case of extractor systems, the power is switched on automatically when the status "OPEN" or "TILTED" is transmitted to the actuator by the window sensors. The switching output is switched off in the "CLOSED", "unlocked, but ajar" and / or "tilted position, but ajar" state.

• Bei „GEKIPPT“: Wenn das Rollo ganz unten oder im unteren Bereich ist, kann es ein wenig zum Lüften hochgefahren werden und nach dem Lüften bei „Zu“, „unverriegelt, aber angelehnt“ und/ oder „Kippstellung, aber angelehnt“ wieder heruntergefahren werden.

For roller shutter / blind drives:

• With "TILTED": If the roller blind is at the very bottom or in the lower area, it can be raised a little for ventilation and then lowered again after ventilation with "Closed", "Unlocked, but ajar" and / or "Tilted position, but ajar" will.

With "OPEN" and / or "unlocked but ajar": If the roller blind is completely down, it can be completely raised when the window is opened. In the event that a roller blind is completely up, you could activate a lock-out protection if the window is "OPEN" or "unlocked but ajar" so that you cannot be locked out by a timer.

With heating controls: During ventilation in the "Open" or "Tilted" state, it makes sense to automatically set the "Frost protection function". With “closed”, “unlocked, but ajar” and / or “tilted position, but ajar”, the “frost protection function” can be deactivated again.

The different sensors and mounting positions may result in compromises in the clear differentiation of all window conditions that are actually present.

Finally, the features of the subclaims can essentially be freely combined with one another and not by the order present in the claims, provided they are independent of one another.

Furthermore, the subject matter of the present invention can be implemented in hardware, software, or a combination of both.
