[0017] As can be seen from at least some of the aforementioned documents, actuation handles are available for various designs and assemblies. In most cases, the locking device is actuated by a handle and a mechanical connection for locking, opening or tilting an object opening.

[0018] Most burglaries occur through window doors, sliding doors or through windows by means of locking mechanisms. These attacks are carried out by prying the locking mechanism open, attacking the window handle directly, attacking the transmission, or by prying the locking mechanism out of the locking plate. Usually, the glass is broken at the level of the window handle, through the opening to reach the handle and turn it to the open position. If the window handle is locked, it can be pried out of its lock by a prying tool and through the opening to the open position. Likewise, there are thieves who drill a hole through the window sash at the level of the window handle and pry the locked window handle into the open position with a specially bent pry bar.

[0019] At present, window handles that can be locked by a separate key are used almost exclusively for purely mechanical security and also in burglar alarm systems to prevent attacks on the window's locking mechanism. These can be pried open and, as experience shows, their locking is ignored after a while. However, over time, it becomes annoying to take the key several times a day, unlock, ventilate, lock, remove the key and put it out of reach. And if nothing happens for a longer period of time, the key is left in the lock or the handle is no longer locked at all for convenience.

[0020] In order to solve this problem and prevent a successful intrusion by tampering with the window handle and turning it into the open position, many manufacturers have introduced electromechanical window handles to the market, which detect the position of the window handle and transmit it independently via radio or cable to an external evaluation unit, usually an alarm panel. If the opening gap is not programmed in this unit, the alarm is triggered in the event of a forced actuation of the actuating handle. The program in the alarm panel is designed so that the window can be opened at a predetermined time, otherwise it remains locked. For example, the window handle disclosed in document [1]

[0021] This window handle is equipped with an electromechanical lock in the rosette. When the window handle is moved, a radio signal is sent to the smart home control center so that it knows in which handle position the handle is. The handle in the closed position is automatically locked by the system - the handle can only be actuated if the system approves the window opening within the parameters set by the user. If this is the case, the window handle is unlocked and can be turned normally. This means that the time at which the lock was performed or the time at which the unlocking is possible must be stored in the alarm center. If the window is to be opened outside of the programmed times, the lock must first be released via the smart home control center. This is not only inconvenient, but also prevents employees or residents from escaping during blocked times in the event of danger.

[0022] The window handle known from [1] also has a predetermined breaking point arranged between the grip and the square pin. If a force greater than the predetermined breaking point is applied in the locked state of the handle, the breaking point breaks. The handle can now be turned, but the window remains locked. Summary of the invention

[0023] The invention is based on the problem of providing an actuating handle which, on the one hand, can be operated more easily and conveniently by the user than before and, on the other hand, still provides greater security against intrusion.

[0024] This problem is solved by an actuation handle according to one aspect of the invention. In another aspect of the invention a device for monitoring and protecting an object against intrusion using one or more such actuation handles is described. Advantageous embodiments of the invention are the subject of further developments of the invention. Furthermore, a corresponding method for monitoring and protecting an object is provided.

[0028] Preferably, the predetermined breaking point is arranged in the housing.

[0029] Preferably, the rotational movement of the handle neck is monitored to monitor the predetermined breaking point.

[0030] Preferably, at least one fastening device and an anti-tamper device are provided for fastening the housing to the window or door leaf, wherein the anti-tamper device is arranged to detect the movement of the at least one fastening device and output information about the movement of the fastening device.

[0039] Preferably, at least one switching bridge is installed between the control unit and the first switching unit.

[0040] Preferably, the actuating handle is configured such that when an authorized finger is placed on the fingerprint scanner before the actuating handle is authorized to be opened, the switch bridge closes the circuit of the first switching unit, so that the switch of the first switching unit which can be actuated by moving the handle neck can be opened during the opening process of the actuating handle without providing information about the break.

[0041] Preferably, the electromechanical lock is unlocked after bridging.

[0042] Preferably, after the actuating handle has been brought into the closed position, the actuating handle is locked electromechanically again.

[0043] Preferably, when the grip is automatically locked, the circuit switches (eg closes) the circuit of the first switching unit so that movement of the handle neck, in particular via a switch acting thereon, again provides information about the break and subsequently at least one switching bridge opens again.

[0044] Preferably, a status monitoring device is provided for monitoring the status of the locking mechanism and for transmitting information about the status to a monitoring center or a control unit.

[0045] Preferably, the state monitoring device has a second switching unit or a second sensor for detecting the position of the locking mechanism, the position of a latch or a catch of the locking mechanism.

[0049] Preferably, the anti-tamper device is configured so that when an attempt is made to unscrew the screw to open or remove the actuating handle, the switch tongue of the switch moves from the larger diameter of the screw to the smaller diameter of the screw or from the smaller diameter of the screw to the larger diameter of the screw, by which movement the circuit is interrupted or closed by the switch due to the detected diameter difference and a tamper alarm is triggered by radio or wired means.

[0050] According to another aspect, the invention relates to a device for protecting an object against intrusion, the object comprising one or more windows and / or one or more doors, the window or door sashes of which are at least partially equipped with an actuating handle according to the preceding description.

[0051] The device preferably comprises at least one further opening detector, preferably comprising a reed switch with opposing magnets, for detecting movement of the actuating handle or a window or door leaf arranged therewith.

[0052] The device preferably comprises at least one glass breakage detector arranged externally of the actuation handle and which is attachable or connectable to the actuation handle.

[0053] Preferably, the device comprises at least one further alarm detector connected or connectable to the actuation handle.

[0054] The device is preferably configured in such a way that sensitization or desensitization of the electronic monitoring unit is performed via an automatic or signal-controlled locking mechanism, or that each individual actuation handle located in the object performs sensitization or desensitization autonomously by an automatic or signal-controlled locking mechanism, directly or via an external connection.

[0055] According to another aspect, the invention provides a method for monitoring an intrusion of an object and for protecting an object against intrusion, characterized in that an actuating handle or device according to the foregoing is used and an alarm is triggered in the event of a breakage of a predetermined breaking point or at least one of a plurality of predetermined breaking points.

[0056] The functions or steps of the actuation handle or of the individual units of the device are implemented, for example, by software in an internal control unit or in an external evaluation unit.

[0057] A preferred embodiment of the present invention provides an actuating handle having a device for protecting and monitoring a window or door against unlawful attacks, wherein at least one electromechanical locking mechanism locks or unlocks a gripping portion of the actuating handle in a locked position against rotational movement in a handle neck, and wherein at least one predetermined breaking point is provided between the gripping portion and the handle neck, wherein the predetermined breaking point is preferably monitored by at least one first electrical switch, in particular a first electrical switch.

[0058] Preferably, the first switch unit, preferably its first switch, is connected to at least one internal or external control unit. Thus, one embodiment of the actuation handle comprises a housing, a handle with a handle neck, a gripping portion and a predetermined breaking point, a breaking monitoring device and a control unit arranged outside or inside the housing, which control unit is correspondingly designed, in particular programmed, to perform the functions described by hardware or software.

[0059] The above-mentioned preferred embodiment operates in such a manner that, in the locked state, a force greater than the resistance of the predetermined breaking point is applied to the gripping portion, causing the predetermined breaking point to break, so that the electrical switch transmits this to the monitoring unit, so that there is no longer any force transmission between the gripping portion and the handle neck, while the electromechanical locking mechanism is still in the engaged state.

[0060] The alarm can thus be triggered without giving the thief access to the object.

[0061] In a particularly preferred embodiment of the invention, in order to prevent tampering from the inside, it is provided that the actuating handle is fastened to the window or door by means of a specially shaped screw, another electrical switch engages the screw, and the screw partially has a larger or smaller diameter. The anti-tampering device preferably operates in such a way that when an attempt is made to turn the screw to open or remove the actuating handle, the switch tongue of the switch of the anti-tampering device moves from the larger diameter of the screw to the smaller diameter of the screw or from the smaller diameter of the screw to the larger diameter of the screw, by which movement the electrical circuit is interrupted or closed by the switch due to the detected diameter difference, and in this way a tampering alarm is triggered by radio or cable.

[0062] Generally speaking, anti-tamper devices work with any fastening device whose movement can be detected by a corresponding switch or other sensor to trigger a message accordingly.

[0063] It is further preferred that the electromechanical locking and / or unlocking is performed by means of a switching device, an alarm system, a fingerprint reader and / or by means of a time detection system. Alternatively or additionally, other keyless, preferably biometric personal identification devices are provided.

[0064] It is further preferred that one or more authorized persons can be identified by means of a fingerprint reader connected to / in or outside the actuating handle, one or more fingerprints are read into an internally or externally connected control unit and stored, and the applied fingerprint is compared directly with the stored fingerprint by radio transmission or wired means.

[0065] It is further preferred that at least one switch bridge is installed, when an authorized finger is placed on the fingerprint reader between the control unit and the fingerprint reader, which closes the circuit of the switch with the switch bridge before authorized opening of the actuating handle, so that the switch can be opened during the process of opening the actuating handle, so that the electromechanical lock is subsequently unlocked, and after the actuating handle is moved to the closed position, it is electromechanically locked again, the circuit closes the circuit of the switch, and then the switch bridge is opened again.

[0066] It is further preferred that the respective state of the unlocking or locking of the locking mechanism is reported to the monitoring unit via a switch on the electromechanical locking mechanism.

[0067] Further preferably, at least one further opening detector can be attached or connected, preferably a reed switch with opposing magnets on or in the actuating handle, and / or at least one external glass break detector and / or a further alarm detector.

[0068] It is further preferred that the sensitization or desensitization of the electronic monitoring unit is performed via an automatic locking mechanism, or that each individual actuating device located in the object performs sensitization or desensitization autonomously by means of an automatic locking mechanism, directly or via an external connection.

[0069] A particularly preferred embodiment of the actuation handle has the following advantages: a unique identification is performed directly on the handle element, the handle element is permanently sensitized, a predetermined breaking point is installed that is electronically monitored and it is connected to an alarm center in order to send an alarm in the event of a violent impact. This particularly preferred embodiment allows the technology to be installed in highly vulnerable objects, such as banks, jewelry stores, etc.

[0070] Advantages and specific aspects of particularly preferred embodiments of the invention are explained in more detail below.

[0071] By a particularly preferred embodiment of the present invention, an actuating handle can be produced, which can also be used in heavily guarded areas and complies with corresponding regulations, such as DIN VDE 0833ff, VdS2311 and other regulations. In order to achieve this, in a particularly preferred embodiment of the present invention, among others, a predetermined breaking point of electronic monitoring, a dedicated circuit in an evaluation unit and an anti-tampering device are installed on the handle element so that the handle element is connected to an alarm center for sending an alarm in the event of a violent impact. This monitoring and electromechanical locking and / or unlocking can be carried out by a switch device, a fingerprint reader and / or a time recording system of the alarm system. In other embodiments designed for areas that are not vulnerable to attack, some of the above-mentioned functions can be omitted.

[0072] When configuring the preferred embodiment of the actuator handle, two different requirements must be additionally considered. For use in residential areas, residents should be protected around the clock. Therefore, it is advantageous if the monitoring technology can be sensitive around the clock. This is in contrast to applications in the commercial sector. During the day, various people, some of whom are from outside the company, must leave the building as quickly as possible in the event of a dangerous situation. Therefore, it is advantageous for such applications if the sensitization only occurs after the last person has left.

[0073] Embodiments of the actuation handle according to the invention may meet these requirements.

[0074] The main advantage of the invention is that a violent attack on the actuating handle (e.g. in the form of a window handle) results in the destruction of the predetermined breaking point, triggering the alarm, the handle can then be turned without being connected to the transmission and the locking mechanism in the window still remains locked.

[0075] Preferably, the electronic monitoring of the predetermined breaking point is simultaneously used as an "opening detector" as specified by the German VdS (German Association of Damage Prevention).

[0076] In a preferred embodiment, a further switch is mounted on the electromechanical locking mechanism of the actuating handle. This switch informs a monitoring device (e.g. an alarm system) whether the actuating handle is locked against rotational movement and therefore whether the window or door is "locked". A "lock detector" is specified by VdS; this can also be implemented by this design or another state monitoring device for monitoring the state of the locking mechanism.

[0077] In complex alarm monitoring systems, security against tampering is required. For example, in alarm-monitored commercial buildings, desensitization is necessary during the day due to possible escape, and the unallowed desensitized handle can be replaced with a normal window handle and then intrusion through this window. To prevent this, in a particularly preferred embodiment of the actuation handle, an alarm-monitored screw fitting or other alarm-monitored fastener is used for tampering resistance.

[0078] The preferred embodiment creates a window handle that triggers a tamper alarm when an attempt is made to unscrew at least one of its two fastening screws.

[0079] In a particularly preferred embodiment, this is provided by a specially shaped and electronically monitored screw. Such a screw is illustrated in the following description and in the accompanying drawings.

[0080] The design of the actuating handle according to the invention, for example in the form of a window handle, can also be used for purely mechanical fixing of an object without connection to an alarm transmission system.

[0081] Further functions of particularly preferred embodiments of the actuation are clear from the description.

[0082] To ensure that the technology on which the invention is based cannot drill through the window or door sash from the outside and thus break or fail, a hardened steel plate or, better still, a break-through monitoring plate or the like may be placed between the rosette and the window sash.

[0083] In order to be able to visually determine the closing state of an individual window in the present case, it will be advantageous if this is indicated by a red (open) or green (closed) diode on the actuating handle.

[0084] In the case of burglar alarm systems, VdS requires that the operator be informed when leaving a building whether all windows are closed and locked. As already mentioned, and as can be seen from the following figures and description, the lock detector integrated in the preferred window handle is directly connected to the burglar alarm panel via an evaluation unit, so that when the operator leaves the building, sensitization is only possible when all object openings are closed and locked, such as by means of block locks.

[0085] Another major advantage of the design of an actuating handle (e.g. in the form of a window handle) with automatic user identification (particularly via a biometric feature such as a fingerprint) is that it no longer needs to be locked. Furthermore, the proposed window handle can be retrofitted into existing burglar alarm systems with all their advantages.

[0086] Intrusion panels (EMA) are often used for intrusion prevention. The requirements for this type of monitoring are different. For example, in residential areas, unlike commercial buildings, 24 / 7 monitoring is required. This is something that the solutions currently available on the market with the best variants of "opening detectors" cannot achieve without triggering false alarms or significantly restricting the freedom of movement of residents. Most false alarms are triggered in connection with sensitization and desensitization.

[0087] Preferred embodiments of the invention allow decentralized solutions in the living area, where each window, each French window and, technically improved, each door can be directly sensitized or desensitized independently of each other, "one line" per window (almost every window), per door. Using these preferred solutions, no false alarms are triggered by improper behavior or erroneous operation. Moreover, due to the predetermined breaking point of the electronic monitoring, any violent attack on the window handle will lead to an alarm in advance, and the window will then remain locked. In this way, the attacker is kept outside the object for a period of time after the alarm has been triggered, making it possible to prevent the attack by intervention.

[0088] In order to achieve this, a keyless personal identification device is provided in a preferred embodiment of the actuating handle, which is activated without a key, preferably biometrically using a unique physical feature of the authorized person himself, such as in particular a fingerprint, or using a device or equipment that the authorized person usually carries with him, such as a smartphone, thereby avoiding the above-mentioned disadvantages of technical solutions requiring a key. Particularly preferably, a fingerprint reader and an internal control unit for automatic locking in the closed state and for release are installed in the rosette or in the gripping part of the actuating handle for unambiguous identification. The fingerprint can be read by the authorized person and the algorithm code can be stored. Unauthorized persons can be deleted.

[0089] In a particularly preferred embodiment of the actuating handle, it is also conceivable that the two switches connected in parallel are connected to a continuously sensitized, electronically monitored predetermined breaking point, which also serves as an "opening detector". If the window is to be opened, a keyless personal identification, in particular a biometric personal identification, is preferably performed, for example by placing an authorized finger on a fingerprint reader. If it is accepted, the first switch is initially switched to "closed". The window handle can then be turned, with the second switch in the open position. In this way, the window handle is ultimately desensitized exclusively internally through the circuit. This is without communication with the intrusion panel. Only the locking detector installed in the window handle will inform that the window is not locked, but has not been overcome by force. If the window handle is placed in the locked position, it will lock itself electromechanically, the "second switch" first closes, then the "first switch" opens, so that forced entry is again seamlessly monitored. The handle unit thus acts decentralized, i.e. independently of external release. If the window is closed again, the locking detector connected to the locking mechanism informs the control unit installed in the window handle and, via the detector, the intrusion panel.

[0090] This means that you don't have to remove the window from the burglar alarm system or other monitor before opening it, and then add it again when you close it, as you did before.

[0091] The preferred window handle can be used on the one hand for integration into an electronic monitoring system and, in the case of different equipment, can also be used for the purpose of machine security with an internal alarm.

[0092] In a preferred solution, each window, French door, sliding door can be controlled independently via an identification system by means of a fingerprint reader or the like connected to an electronic evaluation system, and can be sensitized and desensitized directly at each window, quasi-window-by-window, door-by-door, "on-line" respectively. The advantage of this solution is that all other windows that are not currently open remain permanently sensitized. This means that for the first time, false alarm-free, all-weather protection is guaranteed, especially in properties where people want to move freely, such as residential areas. In addition, this technology acts for people, so false alarms caused by wrong behavior or wrong operation are practically impossible. Therefore, for the first time, people and valuables present are protected around the clock. Another advantage is that a violent attack on the window handle causes the predetermined breaking point to break, the alarm is triggered, and the grip can then be turned without any connection to the transmission device, and the locking mechanism in the window remains locked. The electronic monitoring of the predetermined breaking point is simultaneously used as an "opening detector" as specified by the German VdS (German Association of Damage Prevention).

[0093] The above-described technical solution with personal identification, such as a fingerprint reader, is suitable for electronically monitoring at least some passages in a building, in which strangers are also present, for example in commercial buildings, where people must be able to escape at any time in dangerous situations.

[0094] Here, preferably, personalization is used without the aid of a fingerprint reader. In order to be able to utilize the above-mentioned advantages as much as possible, it makes sense to connect all such electronically monitored actuating handles without a fingerprint reader or similar identification device to a control center, preferably to a burglar alarm panel. Thus, when leaving the building, the locking mechanism can be activated by sensitization and deactivated by desensitization of the so-called block lock. Likewise, the locking detector integrated in the actuating handle can be used to determine whether all windows in the building are locked and the predetermined breaking point is monitored by the opening detector. The great advantage of this technical solution is that even in this variant of the handle, the electronically monitored predetermined breaking point is installed in this handle variant, with the advantages already described.

[0095] The preferred window handle can also be not connected to the alarm forwarding system and can be used in a slightly modified manner for the mechanical, electromechanical protection of the object. This window handle, which is also equipped with a fingerprint reader, is constructed essentially like the handle described above; it can also be an alarm triggering component for an electronically monitored predetermined breaking point, possibly with an integrated siren, which generates an internal alarm in the event of an attack. BRIEF DESCRIPTION OF THE DRAWINGS

[0096] Other features, details and advantages of the present invention will become clear from the present invention and from the following description of exemplary embodiments with reference to the accompanying drawings. The features of the embodiments of the present invention are particularly described by the example of a window with a window handle as an actuating handle; however, the present invention is not limited thereto. As shown below:

[0097] Figure 1 is a cross-sectional view of one embodiment of an actuation handle with electronic monitoring;

[0098] Figure 2 is a top view of an actuation handle with electronic monitoring;

[0099] Figure 3 is an embodiment of the circuit diagram of the actuating handle mentioned in the above-mentioned drawings;

[0100] Figure 4 is a side view of an embodiment of a tamper-resistant device. DETAILED DESCRIPTION

[0101] Figure 1 The device shown in section in FIG. 1 is used to detect and monitor the position of the actuating handle 17 and to transmit the detected position information to an evaluation unit, an alarm system, a bus system or the like.

[0102] The actuating handle 17 has, for example, a handle (window handle) including a grip portion 1 and a handle neck 21, which is mounted on a stopper 14 (e.g., a rosette) having a counter stopper 22 to be axially fixed and rotatable. The actuating handle 17 is secured to the window by screws 101, 102 (which will be referred to later). Figure 4 The invention is described in more detail in detail and is fixed, for example, to a window sash (not shown), wherein a driver 15 (preferably a square pin, fixed in the neck 21 of the handle so that it cannot rotate) engages downstream of the predetermined breaking point 4 in a driver recess 19 suitable for the driver and then in an actuating device (transmission) (also not shown) in the window sash.

[0103] The predetermined breaking point 4 is checked for breaking by a breaking monitoring device which is described in more detail below by way of example.

[0104] In the handle neck 21 is a latch recess 20 (example of latch counter-bearing). If the handle 1 is turned to the "locked" mode, the first switch unit 3 is closed. This sends a signal to the electromechanical locking mechanism 8 installed in the stop body 14 via the first switch unit 3, which now inserts the latch 8a into the latch recess 20 in the handle neck 21. This locks the rotational movement of the handle 1, 21. In order to achieve a higher locking effect, a stabilizer 9 can be connected to the side of the latch 8a. When the latch 8a is locked into the latch recess 20, the second switch unit 7 notifies this signal to the control unit 12 as "locked".

[0105] The stop body 14 of the actuating handle 17 therefore accommodates a plurality of electrical switching units 3 , 7 which transmit the respective position of the handle 1 , 21 via radio or cable to a control unit 12 integrated in the actuating handle 17 or to an evaluation unit (not shown).

[0106] The first switch unit 3 is located on the monitoring lug 2 and monitors the "closed" or "open" state of the actuating handle 17. It is located upstream of the predetermined breaking point 4, as seen from the handle-grip 1. If, in the closed state of the actuating handle 17, a force is applied to the grip 1 that exceeds the resistance of the predetermined breaking point 4, for example in the event of an attempted intrusion, the predetermined breaking point 4 breaks.

[0107] This interrupts the transmission of force from the grip 1 to the actuator 15, the first switch unit 3 switches and signals this to the evaluation unit or control unit 12, the grip 1 can now be operated without a forced connection to the actuator 15, and the window remains locked in the locked state. This process can be reported as an alarm to an alarm panel (not shown) by the evaluation unit or control unit 12 in the stop body 14. The first switch unit 3 and its dedicated circuit are considered to be an "opening detector".

[0108] The second electrical switch unit 7 mounted on the stop body 14 is connected to the latch 8a and monitors the locked and unlocked state of the latch 8a. The respective state of locking or unlocking, shown by the arrow 16, is transmitted via the second switch unit 7 to the evaluation unit or control unit 12, which can, if necessary, transmit it to an alarm panel (not shown). The second switch unit 7 thus serves as a "lock detector" for the alarm panel.

[0109] The diodes 13 may be connected to the stop bodies 14. They indicate to the operator via the closing detector whether the grip 1 is locked by the electromechanical locking mechanism 8 in combination with the latch 8a.

[0110] Another advantageous design of the actuation handle 17 is that the actuation handle 17 is controlled by a fingerprint scanner 11, also called a fingerprint reader (a preferred example of a biometric personal identification device). In the evaluation unit, the control unit 12 or in an external evaluation (not shown), the fingerprint of the authorized person can be scanned. If a person then places his or her finger on the fingerprint scanner 11, the algorithm code is transmitted to the corresponding evaluation unit and checked. If an authorized code is present, the grip 1 is unlocked, which is the opposite of an unauthorized code. In other embodiments, other biometric personal identification devices can be provided, which use at least one previously stored specific biometric feature of the authorized person, or a code input device for entering the authorization code, or an NFC receiver or a Bluetooth interface, etc. to communicate with an authorized stored mobile communication device (especially a mobile phone) or an RFID reader. The personal identification system should be designed in such a way that it can be identified based on features commonly found on people, such as biometric features, stored codes or objects commonly carried, such as mobile phones or RFID chips, so that there is no need to save or use a separate key, and the operation is simple and convenient.

[0111] A fingerprint sensor is particularly preferred.

[0112] In order to detect damage to the electronics in the actuating handle 17 from the outside, a drill hole protection device 6 may be installed between the window sash (not shown) and the stop body 14, or an alarm panel may be installed instead.

[0113] If the actuation handle 17 is to be installed in an object in which foreigners are also present, the technical solution involving fingerprint readers or similar identification devices should not be used for fire protection reasons, at least along the escape route. For such an application of the actuation handle 12, identification, for example by means of a fingerprint reader, is not required, and the control of the locking mechanism 8, 8a can be taken over by the intrusion panel H or another control unit. In this case, the locking mechanism 8, 8a has no effect during the stay of the foreigner and is only activated in case of sensitization of electronic monitoring or the like. The advantage of this technical solution is that the predetermined breaking point 4 of the electronic monitoring triggers an alarm in advance in the event of an illegal attack, and the attacker is then kept outside the object by the still engaged locking mechanism.

[0114] Figure 2 A top view of a window handle is shown - an example of an actuating handle 17 - for electromechanical protection against unauthorized attack.

[0115] Operation is already in Figure 1 Partially shown in Figure 2 Described in detail in.

[0116] The grip 1 is shown, which is fixed by a counter-stop 22 in the stop body 14. In the closed position of the window, the monitoring lug 2 lies on the counter-stop 22. In the closed state of the actuating handle 17, the first switching unit 3 rests with its switching tongue etc. on the monitoring lug 2, wherein the actuating handle 17 is thus in the closed state.

[0117] If opening of the window is permitted via the actuation handle 17, the opening detector, the first switching unit 3 and possibly the further opening detector 10 (which can be mounted in the recess or free space 27 and connected via the connection 26 designed, for example, as a plug-in connection) are removed from the monitoring device via the control unit 12, the electromechanical locking mechanism 8 is powered for retracting the latch 8a, and the window can be opened via the grip 1 without triggering an alarm. The switch details can be found at Figure 3 The required current is provided by an energy storage device such as a rechargeable battery 24 which can be charged via a charging connection 25 .

[0118] from Figure 2 Other details that can be seen in the figure are two stabilizers 9 which hold the latch 8a in the locked state against severe impacts engaging in the recess 20. This is advantageous on the one hand to achieve a higher resistance to the predetermined breaking point 4 and on the other hand to prevent an attacker from exposing the hardware on the window and trying to pry the latch out of the strike plates.

[0119] also, Figure 2An opening 18 is shown through which the actuating handle 17 is fastened to the window sash (not shown) by at least two screws 101, 102 or similar fastening means which are preferably releasable. In order to make it more difficult to turn the grip 1 even when the window is tilted, a further latching recess 20 for the latch 8a may be provided in the handle neck 21.

[0120] The locked or unlocked state can be indicated by a diode 13. In the base of the actuation handle 17 there are two holes 23 through which a cable connection to a reporting centre can be made. The actuation handle 17 has a cover 5 covering the electronics and the like.

[0121] If the actuation handle 17 is used only for purely mechanical protection against unauthorized opening, the first switch unit 3 can be omitted. In this case, the actuation handle 17 is unlocked after the authorized fingerprint is placed on the fingerprint scanner 11 and after the latch 8a is unlocked. In the case of a purely mechanical security system, the locked or unlocked state can also be indicated by the diode 13. In addition, an alarm (not shown) in or outside the actuation handle can be actuated by the first switch unit 3.

[0122] Figure 3 The circuit diagram of the actuating handle 17 mentioned in the above figures is shown. For a heavily guarded area, in addition to the monitored predetermined breaking point 4, further detectors are connected to the actuating handle 17, namely the reed contact of the magnet 10, the glass break detector C1, the attack detector (such as the drilling protection device C1 or the detector for pre-detecting the attempted prying), and the tampering detector C2 (here specially designed as the anti-tampering device 100), which will be explained in more detail below.

[0123] Switches A1 and A2 control the “opening detector”, the first switching unit 3, at a predetermined breaking point 4 which is electronically monitored.

[0124] At the first switch unit 3 (formed by switches A1 and A2), many advantages of the preferred design of the actuation handle 17 in connection with biometric identification, in particular fingerprint schemes, are apparent. These advantages are quasi-sensitizing and desensitizing as well as monitoring individual windows for intrusion.

[0125] In the embodiment shown, unlike the second switch A2, the first switch A1 is not a physical switch, but a programmed switch. In the locked state of the actuating handle 17, the second switch A2 of the first switch unit 3, which is designed as a mechanical switch, is closed and monitors the position of the actuating handle 17. If the previously authorized person places his / her finger on the fingerprint scanner 11 and is recognized as authorized by the control unit 12, the programmed first switch A1 closes the contact to the first switch unit 3, and the second switch A2 is subsequently opened by actuating the actuating handle 17, whereby, due to the switching bridge of the first switch A1, the second switch can be turned to the open position without triggering the alarm. If the window is integrated into an anti-theft alarm system, the actuating handle 17 can be continuously sensitized from the anti-theft alarm panel without having to be desensitized before opening. If the window is closed again, the actuating handle 17 enters the closed position, and the second switch unit 7 sends a signal that the locking mechanism 8, 8a is engaged, the process of switches A1 and A2 is carried out in the opposite order. After this, the actuation handle 17 is again electronically monitored to prevent illegal attacks. Therefore, the first switch A1 is a switch bridge during the opening of the actuation handle 17. Compared with the current technical solutions, since this technology is suitable for the operator, it is no longer possible to trigger false alarms due to misoperation with this procedure.

[0126] The situation is similar if another reed switch with a suitably connected magnet is connected to the circuits B1 and B2 as an external "opening detector" 10. In the case where the actuating handle 17 is used to the highest safety levels, absolutely reliable closing detection must be carried out in accordance with the requirements of the German VdS (German Association for Damage Prevention). Otherwise, an employee of a company, for example, could plan a theft and illegally break in. In the absence of an external opening detector 10 (which is, for example, a switching unit), the employee could ignore a faulty operating lock on the window sash, only incompletely close the window and move the handle to the locked position. The second switching unit 7 would then report a closure after locking 8, 8a, in which case the closure only involves the handle position. Therefore, it is preferred that an external switching unit is designed as an opening detector 10 in the actuating handle 17 for these safety levels.

[0127] like Figure 3As shown, like the second switch unit 3, the external opening detector 10 is constructed as a switch unit having a first switch B1 (in particular in the form of a programming 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 switch units 3 and 10 are programmed so that after closing the second switch A2 of the first switch unit 3, both the switch bridge (of the first switch A1) and the switch bridge at B1 are opened. In the case described here, the second physical switch B2 - in particular designed as a REED contact - is still open on the external opening detector 10 at this time, because this is not applied to the corresponding magnet.

[0128] In this case, the external opening detector 10 will immediately trigger an alarm and in this way prevent erroneous operation or manipulation.

[0129] The main advantage of the above-mentioned technical solution is that all windows of the object are and can remain continuously sensitized, and during opening only each window to be opened after an authorization check is removed from the sensitized state. After the window is closed, it automatically and independently returns to the sensitized mode.

[0130] The connection of the electronically monitored actuating handle 17 to the intrusion panel H is advantageous. When connected to the intrusion panel H (EMZ), the second switch unit 7 (according to Figure 3 The EMZ (designed in the form of a lock monitoring unit D1) specifically indicates the open state when the window is open. However, the first switch unit 3 (with switches A1, A2) indicates that the window is not forced to open but authorized to open. Therefore, this process is not evaluated as an alarm, but is only registered by the EMZ, with the effect that not all windows are closed when leaving the object. When the operator leaves, this is notified by the fact that he cannot switch the block lock, etc.

[0131] In the circuit diagram, further detectors can be connected, such as a glass break detector at C1, a tamper detector at C2 and a drill protection device at C3 etc. If these detectors are to be mounted on the outside of the actuating handle, they need to be tamper-proof, for example, by connecting them to a four-wire cable, of which two wires are connected to the tamper line E1 and, if necessary, to E2. In complex electronic intrusion protection, at least four-wire cables with cables of the same color are used. In order to prevent bridging attempts to remove the detectors in this way from going unmonitored, Z-wiring is used, at the ends of which end resistors G are connected. If an attempt is made to bridge the wires, the resistance thereby changes, which is detected by the alarm panel and reported as an alarm. All detectors shown above are monitored by an integrated evaluation unit 12. It only reports illegal attacks to the alarm panel. An exception is the locking detector - the second switching unit 7 - at Figure 3It is shown as D1 in the circuit diagram of . It has several functions. On the one hand, it informs the electromechanical locking mechanism 8, 8a and the intrusion panel H of the closure, and on the other hand, it controls the diode 13 connected to the stop body 14. Here, the locked or open state is indicated to the operator.

[0132] In the following, Figure 4 An example of an embodiment of a housing 106 for explaining an actuation handle 17 having a tamper-resistant device 100. Figure 1 and 2 As shown, the two parts 1, 21 of the handle are rotatably mounted in the housing 106. Therefore, the predetermined breaking point 4 and the breaking monitoring device are also accommodated in the housing 106. The tamper-proof device is arranged to detect the movement of at least one fastening device, with which the housing 106 is fastened to the window or door leaf, and report accordingly, for example via the connection C2.

[0133] Figure 4 An exemplary embodiment of a tamper-proof device 100 is shown in side view. One embodiment of a tamper-proof device 100 for preventing unauthorized removal of an actuation handle 17 by means of electronically monitored special screws 101 , 102 is shown in side view.

[0134] Window handles 1, 21 ( Figure 4 The housing 106 and the cover 5, 107 (not shown in the figure) are fastened in the thread of the transmission device 105 by special screws 101, 102 passing through the housing 106 and the window covering 104. The special screws 101, 102 have a threaded portion and a larger diameter portion 102, and the switch tongue of the electric switch 103 engages at the larger diameter portion 102 in the assembled state. Since the tampering monitoring is continuous here, the electric switch 103 is in the continuous monitoring mode, that is, it is switched to uninterrupted operation.

[0135] When an attempt is made to unscrew the electronically monitored special screws 101, 102, the switch tongue of the electric switch 103 slides from the larger diameter portion 102 of the special screw towards the smaller diameter portion 101 of the special screw, thereby interrupting or switching the circuit by the switch tongue of the switch 103. This is reported to an evaluation unit (not shown), such as in particular the control unit 12, thereby triggering an alarm.

[0136] Thus, an actuating handle (17) has been described, which is provided with a preferably electromechanical locking mechanism (8, 8a) having a predetermined breaking point (4) which is located between the handle neck (21) and the grip (1) and which is monitored in particular by an electric switch (3), which preferably also serves as an "opening detector". During the authorized opening of the actuating handle (17), the preferably programmed switch (A1) closes the circuit of the electric switch (3), and then the circuit of the preferably physical switch (A2) is opened, so that the grip (1) can be brought to the open or tilted position without the switch (3) triggering an alarm. After the actuating handle has been brought into the closed position and after the electromechanical locking (8, 8a), the process of the switches (A1, A2) is carried out in the reverse order.
