As can be seen from at least some of the above literature references, actuation handles are known in a wide variety of designs and configurations. A locking device is usually actuated by means of a handle and a mechanical connection, which serves to close, open or tilt an object opening.

Most break-ins occur through the French door, sliding door or window, and here via the locking mechanism. These are attacks by levering over the lock, attacks on the window handle directly, on the gearbox or by levering the lock out of the strike plates. Often the glass is broken at the level of the window handle, reached through and the window handle is turned into the opening position. Once the window handle is locked, it can be levered out of its locking position through the opening using a lever tool and into the open position. Similarly, there are also some burglars who drill a hole through the window sash at the level of the window handle and use this to pry the locked window handle into the open position using a specially curved pry bar.

Currently, window handles that can be locked using a separate key are almost exclusively used for purely mechanical security, but also when using burglar alarm systems, to prevent attacks on the window locking mechanism. These can be over-leveraged and experience shows that they are no longer completed after some time. Ventilating several windows several times a day, getting keys, unlocking them, ventilating them, locking them, removing the keys and placing them out of reach becomes annoying over time. And if nothing happens for a long time, the keys get stuck or it is no longer locked for convenience.

In order to solve this problem and to prevent successful break-ins by overcoming the window handle and turning it into the open position, various manufacturers have brought electromechanical window handles onto the market that detect the position of the window handle and do this either autonomously, via radio or wired to an external evaluation unit. usually an alarm center. If no release for opening is programmed in this, an alarm will be triggered if the operating handle is actuated forcefully. The program in the alarm center is therefore designed so that the window can be opened at predetermined times and it otherwise remains locked. Example: the window handle from the literature reference [1].

This window handle is equipped with an electromechanical lock in the rosette. If the window handle is moved, a radio signal is sent to a smart home control center so that it knows which handle position this handle is in. A handle that is in the closed position is automatically locked by the system - it can only be operated if the system gives permission to open the windows, within the parameters specified by the user. If this is the case, the window handle is unlocked and it can be turned normally. This means that the times must be saved in the control center as to when it will be locked and at what time it can be unlocked. If a window is to be opened outside of the programmed times, the locking must first be released via the smart home center. This is not only inconvenient, but in the event of danger it can prevent employees or residents from escaping within the blocked time.

The window handle known from [1] also has a predetermined breaking point installed between the handle and the square pin. If a force above the predetermined breaking point is applied when the handle is locked, the predetermined breaking point breaks. The handle can now be turned, but the window remains locked.

The reference [14] concerns a window handle with a motion sensor, wireless data transmission and self-sufficient energy supply.

It is the object of the invention to provide an operating handle which, on the one hand, is more convenient for users to operate than before, but still offers greater security against burglars.

According to a further aspect, the invention provides a method for monitoring an object with regard to break-ins and for securing the object against break-ins, characterized by using an operating handle or a device according to one of the preceding claims and triggering an alarm in the event of a break in the predetermined breaking point or at least one of several predetermined breaking points.

The mentioned functions or steps of the individual units of the operating handle or the device are implemented, for example, by software in the internal control unit or an external evaluation unit.

A preferred embodiment of the invention creates an operating handle with a device for securing and monitoring a window or a door against unlawful attacks, with at least one electromechanical lock locking or unlocking the handle of the operating handle in the closed position against a rotational movement in the handle neck wherein at least one predetermined breaking point is attached between the handle and the handle neck, this predetermined breaking point being monitored, preferably with at least one first electrical switching unit, in particular a first electrical switch.

Preferably, this first switching unit, preferably its first switch, is connected to at least one internal or external control unit. One embodiment of the operating handle thus includes a housing, a handle with a handle neck, a handle and a predetermined breaking point, a break monitoring device and a control unit arranged outside or inside (the housing), which is designed, in particular programmed, to carry out the functions explained using hardware or software.

This preferred embodiment described above works in such a way that in the locked state, a force acting on the handle that exceeds the resistance of the predetermined breaking point leads to the breakage of the predetermined breaking point, that the electrical switch transmits this to a monitoring unit, so that there is now no longer any force transmission between the handle and the handle neck , with the electromechanical lock still engaged.

This means an alarm can be triggered without the burglar getting into the property.

In order to prevent sabotage from the inside, in a particularly preferred embodiment of the invention it is provided that the operating handle is attached to the window or door with a specially shaped screw, that there is a further electrical switch on the screw and that the screw partially has a larger or has smaller diameter. The tamper protection preferably works in such a way that when an attempt is made to unscrew this screw in order to open or remove the operating handle, the switching tongue of the tamper protection switch is moved from the larger diameter to the smaller diameter of the screw or from the smaller diameter to the larger diameter of the screw Through this movement, as a result of the detected difference in diameter, a circuit is either interrupted or closed by the switch and in this way a sabotage alarm is triggered by radio or wired.

Generally speaking, the sabotage protection works with any fastening device whose movement can be detected by a corresponding switch or other sensor in order to trigger a corresponding message.

It is further preferred that the electromechanical locking and/or unlocking takes place by means of a switching device, an alarm system, a fingerprint reader and/or by means of a time recording system. Alternatively or additionally, other keyless, preferably biometric, personal identification devices are provided.

It is further preferred that one or more fingerprints are read and stored in an internally or externally attached control unit by one or more authorized persons via a print reader, which is attached either to/in the operating handle or externally, and that an applied fingerprint is included the stored fingerprints are compared directly, via radio transmission or wired.

It is further preferred that when the authorized finger is placed on the print reader, at least one switching bridge is installed between the control unit and the switch, which connects a circuit of the switch with a before the authorized opening of the operating handle Switching bridge closes so that the switch can open when the operating handle is opened, that the electromechanical locking is then unlocked, that after the operating handle has been moved into the closed position, it is locked again electromechanically, that the circuit closes the circuit of the switch and that then the Open switching bridges again.

It is further preferred that the respective state of the lock, unlocked or locked, is reported to a monitoring unit via a switch on the electromechanical lock.

It is further preferred that at least one further opening detector, preferably a reed switch with an opposite magnet, can be attached or connected to or in the operating handle, and/or at least one external glass break detector and/or further alarm detectors.

It is further preferred that an electronic monitoring unit is armed or disarmed via the automatic locking, or that each individual actuating device located in an object is independently armed or disarmed by means of the automatic locking, directly or via an external connection Disarming is carried out.

Particularly preferred embodiments of the operating handle have the advantages of carrying out a clear identification directly on the handle element, permanently arming this handle element, installing an electronically monitored predetermined breaking point and connecting it to an alarm center for transmitting an alarm in the event of violence. Such particularly preferred configurations make it possible for this technology to also be installed in highly vulnerable objects, such as banks, jewelers, etc.

Advantages and special aspects of particularly preferred embodiments of the invention are explained in more detail below.

A particularly preferred embodiment of the invention makes it possible to generate an operating handle that can also be used in the high-security area and that meets the respective regulations, such as DIN VDE 0833 ff, VdS 2311 and others. In order to achieve this, in a particularly preferred embodiment of the invention, an electronically monitored predetermined breaking point, a special circuit in the evaluation unit, and a sabotage protection device are installed on the handle element, among other things, in order to connect these to an alarm center for transmitting an alarm in the event of violence. This monitoring as well as electromechanical locking and/or unlocking can be carried out using a switching device of an alarm system, a fingerprint reader and/or using a time recording system. In other embodiments designed for less sensitive areas, some of the aforementioned functions may be omitted.

When configuring preferred embodiments of the operating handle, two different requirements must also be taken into account. Use in inhabited areas should protect residents around the clock. It is therefore advantageous if the surveillance technology can be activated around the clock. In contrast, there is an application in the commercial sector. Different people, some of whom are external to the company, move around here during the day and who will quickly leave the building in the event of a dangerous situation must, which is why it is advantageous if, for such applications, the arming only takes place after the last person has left.

These requirements can be met with embodiments of the actuating handle according to the invention.

A major advantage of the present invention is that a violent attack on the operating handle, e.g. in the form of a window handle, results in the predetermined breaking point breaking, an alarm being triggered, the handle piece then being able to be rotated without connection to the gearbox and the locks in the Windows remain locked.

Preferably, the electronic monitoring of the predetermined breaking point also serves as an “opening detector” within the meaning of the regulations of the Association of Damage Prevention VdS.

In preferred embodiments, a further switch is attached to the mechatronic lock of the operating handle. This switch informs a monitoring device, for example an alarm system, whether the operating handle is locked against a rotational movement and thus the window or door is "locked" or not. A “closure detector” is required by the VdS; This can also be achieved with such a configuration or another condition monitoring device for monitoring the condition of the lock.

In sophisticated alarm monitoring, secure sabotage protection against manipulation is required. For example, in the case of an alarm-monitored commercial property that has to be disarmed during the day due to escape options, an unauthorized, disarmed handle could be replaced with a normal window handle and later broken in using this window. To prevent this, in a particularly preferred embodiment of the operating handle, an alarm-monitored screw connection or another alarm-monitored fastening is used to protect against sabotage.

Preferred embodiments create a window handle that triggers a sabotage alarm if an attempt is made to unscrew at least one of the two fastening screws of the window handle.

This is guaranteed in a particularly preferred embodiment with a specially shaped and electronically monitored screw. One such is shown in the following description and drawing.

Versions of the operating handle according to the invention, such as in the form of a window handle, can also be used for purely mechanical security of an object without being connected to an alarm relay.

Further functions of particularly preferred embodiments of the operating handle can be found in the description.

In order to ensure that the technology on which the invention is based cannot be drilled through the sash from the outside and thus destroyed or disabled, a hardened steel plate, or better, a circuit board that monitors breakthroughs or the like, can be placed between the rosette and the window sash be placed.

So that the closed status of the individual window can be visually determined when someone is present, it would be advantageous if this were indicated by a red (open) or green (closed) diode on the operating handle.

In the case of a burglar alarm system, if the insurance level is appropriate, the VdS requires that the operator is shown when leaving the building whether all windows are closed and locked. As already mentioned, it can be seen from the following drawings and the description, the lock detector integrated in the preferred window handle is connected directly to an intruder alarm center via the evaluation unit, so that when leaving the building it can only be armed using the block lock or the like if all Object openings are closed and locked.

Another extreme advantage of the embodiments of the operating handle with automatic user identification, in particular via biometric features such as fingerprints, is that it no longer needs to be locked, for example in the form of a window handle. In addition, the proposed window handle can be retrofitted into existing burglar alarm systems with all its advantages.

Burglar alarm systems (EMA) are often used to protect against break-ins. The requirements for such monitoring are different. In contrast to commercial properties, residential areas should be monitored around the clock. This cannot be achieved with the solution currently on the market with "opening detectors", the best variant, without triggering false alarms or significantly restricting the residents' freedom of movement. The majority of false alarms are triggered in connection with the arming/disarming switch.

Preferred embodiments of the invention enable a decentralized solution in the living area in which every window, every French door and, technically modified, every door can be armed or disarmed independently of one another, directly at each window, so to speak for each window door, "a line". With these preferred solutions, no false alarms are triggered due to incorrect operation or incorrect operation. In addition, due to the electronically monitored breaking point, any violent attack on the window handle triggers an alarm in advance and the window remains locked afterwards. In this way, an attacker is kept outside the object for some time after the alarm is triggered, so that the intervention has the opportunity to prevent the attack.

In order to achieve this, in preferred embodiments of the operating handle, a keyless personal identification device is provided, which is without a key, preferably biometrically with unique body characteristics of the authorized persons themselves, such as in particular fingerprints, or with devices or devices that an authorized person usually carries with them , such as a smartphone, works, so that the aforementioned disadvantages of the key solution are avoided. Particularly preferably, a fingerprint reader and an internal control for automatic locking in the closed state and for release are installed in the rosette or in the handle of the operating handle for clear identification. Authorized people can read their fingerprints and save the algorithmic codes. People who are no longer eligible can be deleted.

In a particularly preferred embodiment of the operating handle, it is further provided that two switches connected in parallel are attached to the continuously armed, electronically monitored predetermined breaking point, which simultaneously acts as an "opening detector". If the window is to be opened, a preferably keyless personal identification, in particular a biometric personal identification, is carried out, for example an authorized finger is placed on a fingerprint reader. If it is accepted, the first switch switches to “Closed”. The window handle can then be turned, with the second switch going into the open position. In this way, the window handle is only disarmed internally using this circuit. This is not communicated to the intruder alarm center. She only receives a message via the locking detector installed in the window handle that the window has not been locked but has not been breached by force. If this window handle is brought back into the closed position, it locks itself electromechanically, the "second switch" closes first, then the "first switch" opens, so that monitoring for the effects of violence takes place seamlessly again. This handle unit therefore acts decentrally, i.e. independently of an external release. If this window is closed again, the locking detector attached to the lock informs the control unit installed in the window handle and, via this, the intruder alarm center.

This means that this window does not have to be removed from the monitoring of the burglar alarm system or other monitoring before opening and then added back when closing.

The preferred window handle can be used for integration into electronic monitoring and, when equipped differently, for mechanical security, also with an internal siren.

In the preferred solution, each window, each window door, each sliding door can be armed or disarmed independently of one another via identification with a print reader or the like, connected to evaluation electronics, directly on each window, so to speak for each window. each door, a "line". The advantage of this solution is that all other windows that are not currently being opened are still permanently armed. This means that, for the first time, false alarm-free, round-the-clock protection is guaranteed, especially in objects where people want to move freely, such as living areas. In addition, this technology acts for people, so that false alarms caused by misconduct or incorrect operation are virtually impossible. For the first time, people present and valuables are seriously protected around the clock. Another advantage is that a violent attack on the window handle results in the predetermined breaking point breaking, an alarm is triggered, the handle can then be turned without being connected to the gear and the locks in the window still remain locked. The electronic monitoring of the predetermined breaking point also serves as an "opening detector" in accordance with the regulations of the Association of Damage Prevention VdS.

The aforementioned solution with personal identification, such as the print reader, is not advantageous for electronic monitoring of at least some passages in a building in which strangers are also present, for example in commercial properties that must be able to escape at any time in the event of danger.

Preferably no individualization using a print reader is used here. In order to be able to use the previously described advantages to the greatest extent possible, it makes sense to connect all such electronically monitored actuation handles to a control center, preferably an intruder alarm center, without a print reader or similar identification device. This can be used to activate the locks when leaving the building, via a so-called block lock, when arming and to deactivate when disarming. The locking detector integrated in the operating handle can also be used to determine whether all windows in the property are closed and monitored by the opening detector at the predetermined breaking point. The big advantage of this solution is that the electronically monitored predetermined breaking point with the advantages already described is also installed in this handle variant.

The preferred window handle can also be used for mechanical, mechatronic security of an object, without being connected to an alarm forwarding and in a slightly modified manner. This window handle, which is in turn equipped with a print reader, is constructed largely like the handle described above; it can also contain the alarm-triggering component of the electronically monitored predetermined breaking point, possibly with an integrated siren that generates an internal alarm in the event of an attack.

Further features, details and advantages of the invention emerge from the wording of the claims and from the following description of exemplary embodiments based on the drawings. Features of exemplary embodiments of the invention are shown in particular using the example of a window with a window handle as an operating handle; but the invention is not limited to this. Show it:

• Fig. 1 a sectional view of an exemplary embodiment of an operating handle with electronic monitoring,
• Fig. 2 the operating handle with electronic monitoring in a top view,
• Fig. 3 an exemplary embodiment of a circuit diagram of the actuation handle mentioned in the aforementioned figures, and
• Fig. 4 in side view an embodiment of a sabotage protection.

In the Figure 1 The device shown in a sectional view is used to record and monitor the position of an operating handle 17, as well as to transmit the recorded position information to an evaluation unit, an alarm system, a bus system or the like.

The operating handle 17 has, for example, a handle (window handle) - consisting of a handle 1 and a handle neck 21 - which is mounted with a counter-stop 22 in an axially fixed and rotatable manner on a stop body 14, for example a rosette. The operating handle 17 will be explained in more detail later using Fig. 4 explained screws 101, 102, for example attached to a window sash, also not shown, with a driver 15, preferably a square pin, fixed in a rotationally fixed manner in the handle neck 21, after a predetermined breaking point 4 into a driver recess 19 adapted to the drivers and then into a driver recess 19, also not The actuating device (gear) shown engages in the window sash.

The predetermined breaking point 4 is monitored for a break by means of a break monitoring device explained in more detail below as an example.

There is a bolt recess 20 in the handle neck 21 (example of a bolt counter bearing). If the handle 1 is turned into the “closed” mode, a first switching unit 3 is closed. The first switching unit 3 reports this to an electromechanical lock 8 mounted in the stop body 14, which now inserts a lock 8a into the lock recess 20 in the handle neck 21. This blocks the rotation of the handle 1, 21. In order to achieve a higher locking effect, stabilizers 9 can be attached to the side of the bolt 8a. If the bolt 8a is locked in the bolt recess 20, a second switching unit 7 reports this to a control unit 12 as “locked”.

In the stop body 14 of the operating handle 17 there are several electrical switching units 3, 7, which send the respective status of the handle 1, 21 via radio or wired to the control unit 12 integrated in the operating handle 17 or to an evaluation unit, not shown.

The first switching unit 3 sits on a monitoring nose 2 and monitors the "closed" or "open" state of the operating handle 17. As seen from the handle - handle 1 - it is positioned in front of the predetermined breaking point 4. If, in the closed state of the operating handle 17, a force exceeding the resistance of the predetermined breaking point 4 is applied to the handle 1, for example in the event of a break-in attempt, the predetermined breaking point 4 breaks. This interrupts the force transmission of the handle 1 to the driver 15, the first switching unit 3 switches, reports this to the evaluation unit or control unit 12, the handle 1 can now be rotated to the driver 15 without a force connection, the window remains locked in the locked state. This process can be reported as an alarm to an alarm center (not shown) by the evaluation unit or control unit 12 in the stop body 14. The first switching unit 3, with its special circuit, is to be viewed as an “opening detector”.

The second electrical switching unit 7 installed on the stop body 14 rests on the bolt 8a and monitors the locked and unlocked state of the bolt 8a. This respective state, locked or unlocked, shown with the arrow 16, is passed on by the second switching unit 7 to the evaluation unit or control unit 12, which, if required, can forward it to the alarm center, not shown. The second switching unit 7 thus acts as a so-called “closure detector” for the alarm center.

Diodes 13 can be attached to the stop body 14. These show the operator via the locking indicator whether the handle 1 is locked or not locked via the electromechanical lock 8, in conjunction with the bolt 8a.

A further advantageous embodiment of the operating handle 17 is that the operating handle 17 can be controlled by means of a fingerprint scanner 11 - also called a print reader (preferred example of a biometric personal identification device). Fingerprints can be scanned by the authorized persons either in the evaluation unit, the control unit 12 or in an external evaluation (not shown). If a person subsequently places their finger on the fingerprint scanner 11, the algorithmic code is communicated to the respective evaluation unit and checked. If the authorized code is present, handle 1 is unlocked, in contrast to the unauthorized code. In other embodiments, other biometric personal identification devices that have at least one previous recorded specific biometric characteristic of an authorized person, or a code input device for entering an authorization code can be provided, or an NFC receiver or a Bluetooth interface or the like for communication with a mobile communication device stored as authorized (in particular a mobile phone) or an RFID reader be provided. The personal identification should be designed in such a way that it can carry out identification based on characteristics usually found on the person, such as biometric characteristics, memorized codes or items typically carried with them such as mobile phones or universally applicable RFID chips, so that no separate key is kept or used must and the operation remains simple and convenient. Fingerprint sensors are particularly preferred.

In order to detect manipulation of the electronics in the operating handle 17 from the outside, a drilling protection 6, or instead a signaling board, can be installed between the window sash (not shown) and the stop body 14.

If the operating handle 17 is to be installed in objects in which strangers are also staying, the solution with the print reader of the same identification device should not be used for fire protection reasons, at least on escape routes. For such uses of the operating handle 12, identification, for example by means of the print reader, is no longer necessary, and the control of the lock 8, 8a can be taken over by an intruder alarm center H or by another control unit. In this case, the lock 8, 8a is inoperative while the strangers are there and is only locked when an electronic surveillance device or the like is armed. The advantage of this solution is that the electronically monitored predetermined breaking point 4 triggers an alarm in advance in the event of an illegal attack and that the attacker is then kept outside the object via the lock, which is still engaged.

Figure 2 shows a top view of the window handle - example of the operating handle 17 - for mechatronic security against unlawful attacks.

The functionality has already been partly explained in the Figure 1 shown and is included in Fig. 2 described in detail.

The handle 1 is shown, which is fastened with the counter-stop 22 in the stop body 14. The monitoring lug 2 is located on the counter stop 22 when the window is in the closed position. The first switching unit 3 rests with its switching tongue or the like on the monitoring lug 2 when the actuating handle 17 is closed, the actuating handle 17 is therefore closed.

If the authorization to open the window is granted via the operating handle 17, the opening detector, first switching unit 3, and possibly a further opening detector 10, which is mounted in a recess or a free space 27 and via a connection 26 designed, for example, as a plug-in connection, is activated via the control unit 12 can be connected, removed from monitoring, the electromechanical lock 8 is supplied with power to retract the bolt 8a and the window can be opened via the handle 1 without triggering an alarm. The switching details are taken from the Figure 3 visible. The electricity required is provided by an energy storage device, such as a battery 24, which can be charged via a charging port 25.

More visible details from the Figure 2 are the two stabilizers 9, which hold the bolt 8a in the locked state against the effects of force in the recess 20. This is advantageous, on the one hand, in order to achieve a higher resistance to the predetermined breaking point 4, and on the other hand, to prevent an attacker from exposing the fittings on the window and trying to lever the bolts out of the striking plates.

Furthermore, it shows Figure 2 Openings 18 through which the actuating handle 17 is preferably releasably attached, in particular screwed, to the wing, not shown, with at least two screws 101, 102 or similar fastening means. To make it more difficult to turn the handle 1 even when the window is tilted, a further latch recess 20 can be provided in the handle neck 21 for the latch 8a.

The locked or unlocked state can be displayed via diodes 13.

In the bottom of the operating handle 17 there are two openings 23 through which a cable connection to a signaling center is made possible. The operating handle 17 has a cover 5 which covers the electronics and the like.

If the operating handle 17 is to be used exclusively for purely mechanical protection against unauthorized opening, the first switching unit 3 can be omitted. In this case, the operating handle 17 is unlocked after placing the authorized fingerprint on the fingerprint scanner 11 and after unlocking the latch 8a. Even with purely mechanical security, the locked or unlocked state can be displayed via diodes 13. In addition, a siren, not shown, can be controlled in or outside the operating handle via the first switching unit 3.

Fig. 3 shows the circuit diagram of the operating handle 17 mentioned in the aforementioned figures. For the high security area, further detectors are connected to the operating handle 17, in addition to the monitored predetermined breaking point 4, a reed contact with magnet 10, a glass break detector C1, an attack detector (e.g. drill protection C1 or a detector, which detects an attempt to pry open in advance) and a sabotage detector C2, here in particular designed as a sabotage protection 100, as will be explained in more detail below.

Switches A1 and A2 control the "opening detector", first switching unit 3, at the electronically monitored predetermined breaking point 4.

The extreme advantage of the preferred embodiment of the actuation handle 17 can be seen on the first switching unit 3 (formed by the switches A1 and A2), in conjunction with the biometric identification, in particular a print solution. What they have in common is the arming/disarming switch and monitoring against break-ins of individual windows.

In the embodiment shown, in contrast to the second switch A2, the first switch A1 is not a physical switch, but a programmed switch. When the operating handle 17 is closed, the second switch A2 of the first switching unit 3, which is designed as a mechanical switch, is closed and monitors the position of the operating handle 17. If a previously authorized person places his finger on the fingerprint scanner 11 and he is identified as authorized by the control unit 12, it closes the programmed first switch A1 the contact to the first switching unit 3, the second switch A2 then opens when the operating handle 17 is actuated, whereby it can be rotated into the open position without triggering an alarm due to the switching bridge of the first switch A1. If this window is integrated into a burglar alarm system, the operating handle 17 can be continuously armed from the perspective of the burglar alarm center without having to be disarmed before opening. If the window is closed again, the operating handle 17 is brought into the closed position, and the second switching unit 7 reports that the lock 8, 8a is engaged, the procedure for the switches A1 and A2 runs in the reverse order. The operating handle 17 is then electronically monitored again against illegal attacks. The first switch A1 is therefore a switching bridge for the duration of the opening of the operating handle 17. False alarms due to incorrect operation can no longer be triggered with this procedure because the technology acts for the operator, in contrast to current solutions.

The situation is similar if another reed switch with a correspondingly attached magnet is connected to the circuit B1 and B2 as an external “opening detector” 10. In the event that the operating handle 17 is to be used up to the highest security classes, absolutely reliable lock detection must take place, as demanded by the Association for Damage Prevention (VdS). Otherwise, for example, a company employee could plan a theft and present it as a burglary. Without the external opening detector 10, which is designed, for example, as a switching unit, it could override the incorrect operation lock on the window sash, not close a window completely and bring the handle into the closed position. The second switching unit 7 would then report a lock after the lock 8, 8a, which in this case only affects the handle position. An external switching unit must therefore be provided as an opening detector 10 in designs of the operating handle 17 that are designed for use in these security classes.

As in Fig. 3 shown, the external opening detector 10 is constructed like the second switching unit 3 as a switching unit with a first switch B1, in particular in the form of a programmed switch, and a second switch B2, in particular in the form of a physical switch, these switches B1, B2 of the external opening detector 10 are also connected in parallel. The switching units 3 and 10 are programmed so that after closing the second switch A2 of the first switching unit 3, both the switching bridge (of the first switch A1) and the switching bridge at B1 are opened. In the case described here, the physical second switch B2 - in particular designed as a REED contact - would still be open on the external opening detector 10 at this point in time, since it is not in contact with the corresponding magnet.

In this case, this external opening detector 10 would immediately trigger an alarm and in this way prevent incorrect operation or manipulation.

The extreme advantage of this solution described above is that all windows of an object are and can remain armed at all times and that only the window that is to be opened after the authorization check is removed from the arming for the duration of the opening. After closing the window, it automatically returns to arming mode.

A connection of the electronically monitored operating handle 17 to an intrusion alarm center H is advantageous. When connected to an intruder alarm center H (EMZ), this is activated when the window is opened via the second switching unit 7 (according to Fig. 3 executed in the form of a closure monitoring D1) only the opening status is displayed. However, the first switching unit 3 (with switches A1, A2) indicates that the window was not forcibly overcome, but was opened authorizedly. Therefore, this process is not considered an alarm, but is simply registered by the EMZ to the effect that not all windows are closed when the property is left. This is communicated to the operator when he leaves because he cannot switch the block lock or the like.

Additional detectors can be connected in the circuit diagram, for example a glass break detector at C1, a sabotage detector at C2 and a drill protection device at C3 or the like. If these detectors are to be installed outside the operating handle, sabotage protection is required, for example in such a way that a 4-wire cable is connected to these detectors, with two strands being connected to the tamper line E1 and, if necessary, to E2. In sophisticated electronic burglary protection, at least a 4-core cable with strands of the same color is used. To prevent bridging attempts to remove a detector from monitoring, the so-called Z-wiring is used, at the end of which a line end resistor G is attached. If an attempt is made to bridge the strands, the resistance changes, which is recognized by the alarm center and reported as an alarm. All detectors shown above are monitored by the integrated evaluation unit 12. It only reports an unlawful attack to the alarm center. The exception to this is the closure detector - second switching unit 7 - which is shown in the circuit diagram Fig. 3 is shown as D1. It has several functions. On the one hand, it communicates the closure of the electromechanical lock 8, 8a and the intruder alarm system H and, on the other hand, it controls the diode 13 attached to the stop body 14. The locking or opening status is displayed to the operator here.

The following is based on the Fig. 4 an exemplary embodiment of a housing 106 of the operating handle 17 with a tamper protection 100 is explained. As the Fig. 1 and 2 show, both parts 1, 21 of the handle are rotatably mounted in the housing 106, so the predetermined breaking point 4 and the break monitoring device are also housed in the housing 106. The tamper protection is designed to detect a movement of the at least one fastening means with which the housing 106 is fastened to the sash of the window or door and to report it accordingly, for example via connection C2.

Fig. 4 shows a side view of an exemplary embodiment of the sabotage protection 100. Shown in a side view is an embodiment of the sabotage protection 100 against illegal removal of the operating handle 17 by means of an electronically monitored special screw 101, 102.

Shown is the housing 106 of the in Fig. 4 Window handle 1, 21, not shown, and the cover 5, 107, which is fastened with the special screw 101, 102 through the housing 106 and through the window flap 104 in the screw thread of the gear 105. The special screw 101, 102 has a threaded part and a larger diameter part 102 on the one mounted in the State the switching blade of an electrical switch 103 is applied. Since the sabotage monitoring should take place continuously here, the electrical switch 103 is in continuous monitoring mode, i.e. switched to continuity.

When attempting to unscrew the electrically monitored special screw 101, 102, the switching tongue of the electrical switch 103 slides from the larger part of the diameter 102 of the special screw to the smaller diameter part 101 of the special screw, whereby the switching tongue of the switch 103 interrupts or switches the circuit. This is reported to the evaluation unit, not shown - in particular, for example, the control unit 12 - whereupon an alarm is triggered.

An operating handle (17) has thus been described, provided with a preferably electromechanical lock (8, 8a), with a predetermined breaking point (4), which is located between a handle neck (21) and a handle (1) and in particular with a Electrical switch (3) is monitored, which preferably also serves as an “opening detector”. When the operating handle (17) is opened authorized, a preferably programmed switch (A1) closes the circuit of the electrical switch (3), then the circuit of a preferably physical switch (A2) is opened, so that the handle (1) is activated without an alarm being triggered by the switch (3) can be brought into the open or tilt position. After placing the operating handle in the closed position and after the electromechanical locking (8, 8a), the procedure for the switches (A1, A2) runs in the reverse order.
