Abstract

The invention relates to an arrangement (14) for monitoring the opening state of a lockable component (1) that has a stationary frame (3), a movable leaf (4), and a lock fitting (7) that can be moved between a locking position (11) and a release position (12), comprising a magnetic sensor (15) arranged on the leaf (4), a magnet (16) fastened to the frame (3) so as to be adjacent to the magnetic sensor, wherein an increase in the distance (26) between the magnetic sensor (15) and the magnet (16) causes a switching process of the magnetic sensor (15), a fitting position sensor (41) that detects the locking position (11, 13) or the release position (12), and an evaluating unit (42) coupled to the magnetic sensor (15) and the fitting position sensor (41). The magnetic sensor (15) is designed as a normally closed contact, which interrupts a circuit by opening the contact under the influence of a magnetic field, and activates the evaluating unit (42) from an idle state by a switching process. The evaluating unit (42) activates the signaling device or the alarm system immediately after the switching process if there is a locking position (11, 13) detected by the fitting position sensor (41).

Description

Monitoring arrangement for the opening state of a window or a door

The invention relates to a monitoring arrangement for the opening state of a vergel- gelbaren device according to the preamble of claims 1 and 2.

As a measure for protection against unauthorized intrusion by a locked window or a locked door, it is state of the art to detect and monitor the closed state of the sash by providing the frame and sash with a combination of a magnetic sensor and a magnet, wherein when unauthorized opening, the distance between them is increased and thereby triggered a switching signal of the magnetic sensor is used to trigger an alarm. In order that opening of the unlocked window does not lead to an alarm triggering, it is also state of the art to additionally monitor the state of the lock by interrogating the engagement of locking elements such as locking bolts, etc. in strikers and monitoring the opening of the wing only after the Locking the same is activated. This can also be accomplished by means of magnetic sensors and magnets suitably arranged on the locking fittings of such a device. Such a monitoring arrangement, with both a monitoring of the open state and the locking state is, for example, from EP 0 763 644 AI known, but such systems consistently require several, generally arranged on the frame magnetic sensors and, accordingly, a complex control for evaluation and logical connection of the many possible switching signals require. The object of the invention is to provide a monitoring arrangement for the opening state of a lockable component, which offers reliable protection against unauthorized opening of the locked component with little construction effort.

The object of the invention is achieved by a monitoring arrangement with the features of claim 1.

In this case, the distance between the wing and frame is monitored by means of the magnetic sensor and in the case of an increase in distance based on the means of a Beschlagstellungs- Detected sensor position of the locking element on the presence of a normal or an unauthorized violent opening of the device. The advantage here is that due to the use of a magnetic sensor in the form of an opener, the evaluation can be very simple and is activated in a simple manner in response of the magnetic sensor and then simply by means of the fitting position sensor a simple query of the locking state is performed. As a result, the evaluation unit consumes only very little or no current in the idle state or in the standby state, which is why this monitoring arrangement is also optimally suited for a power supply with batteries, thereby reducing the installation effort.

The Beschlagstellungs-sensor can be designed in various ways, such as a switch which is mechanically coupled to an adjustable part of the locking fitting and assigned the unlocking position or the locking position certain switching positions. Alternatively, a non-contact detection of the locking position, for example by means of magnetic magnetic sensor arrangements or other proximity switches, in which a Relatiwerschiebung leads to corresponding switching operations. A possible embodiment consists in an additional magnetic sensor in the form of an opener, which is held in the unlocked position by a magnet in the open position and closes when moving to the locking position or to the tilted position due to the missing magnetic field. However, it is also possible to interrogate the locking position or the tilting position in each case with a magnetic sensor in the form of a closer, which is closed when approaching a coupled to the locking element magnet.

A position measurement with grinding resistance elements or the like can also be used if the evaluation unit can derive therefrom the corresponding positions of the locking element.

The object of the invention is alternatively achieved by a monitoring arrangement according to claim 2.

The special arrangement of the magnetic sensor or the additional magnetic sensor causes in this embodiment of the invention that an alarm is triggered only when the locking element or the locking elements are in the locked position and the wing by applying force its distance from the frame increased. By approaching the magnetic sensor or the additional magnetic sensor to the additional magnet when adjusting the locking fitting in the unlocking the monitoring assembly is automatically defocused and does not trigger a switching signal at opening the wing, as the magnetic sensor or connected in series with this additional magnetic sensor in the magnetic field of the additional magnet is located. If the locking element is transferred by appropriate operation in the locking position, which makes sense only when the wing on the frame, the monitoring device is automatically armed by the magnetic sensor is in this position only in the sphere of influence of the frame mounted magnet and an increase in distance to a Attempt of penetration under use of force indicates that triggers a corresponding switching signal of the magnetic sensor. It is thus logically linked with only one magnetic sensor and optionally an additional magnetic sensor, both the locking state of the lock and the closed state of the wing and requires the monitoring arrangement no separate measures for arming or disarming, which is why despite low construction effort reliable monitoring is present, which is also unattractive is against false alarms.

In the embodiment variant with an additional magnetic sensor, the magnetic sensor, with which the position of the wing is monitored with respect to the frame, be fixed relative to the wing fixed thereto or be movably coupled with the locking element coupled to the wing movable adjustable on the wing, in both Cases where the magnetic sensor is located in the magnetic field of the magnet on the frame when the wing is locked or tilted. An advantage of the monitoring arrangement according to the invention is that the magnetic sensor or the additional magnetic sensor is an opener, which opens a circuit by contact interruption under the influence of a magnetic field. As a result, no current flows in the circuit in any normal operating state, which means that power sources in the form of batteries can have a very long standby time. With activated locking elements, namely, the magnetic sensor is in the influence of the magnet attached to the frame, while it is in the unlocked position with the wing open with the locking element in the influence of the additional magnet or the additional magnetic sensor is in the influence of the additional magnet whereby the circuit is thus only closed if the lock elements are active and at the same time the distance between the magnetic sensor and magnet is increased, as is the case with a burglary attempt. For example, when using lithium batteries or silver oxide batteries, a lifespan of over 5 years up to 10 years can be ensured.

According to an advantageous development of the monitoring device magnetic sensor and Beschlagstellungs-sensor or magnetic sensor, additional magnetic sensor and optionally additional magnet, in particular in a common housing, combined to form a wing-mounted assembly, whereby the assembly of such a monitoring device, especially if they are done later should be much easier and faster and the spatial arrangement of the components already fixed to each other before mounting, which also eliminates a lot of work for the adjustment of the magnetic sensor, the fitting position sensor or the additional magnetic sensor to the additional magnet.

The Beschlagstellungs-sensor or the magnetic sensor and / or the additional magnetic sensor can be arranged on a unit, in particular in the form of a housing, adjustably mounted and bewegungskoppelbaren with the locking element actuator, whereby the movement of the actuator directly an identical movement of the magnetic sensor or causes the additional magnetic sensor without a conversion of the movement would be required by transmission elements.

A structurally advantageous embodiment of the monitoring arrangement is that fitting position sensor and / or magnetic sensor and / or additional magnetic sensor are arranged on a strip-shaped actuator, which is mechanically coupled to the locking element. The longitudinal axis of the actuator extends approximately in the adjustment of the locking element and is further the actuator directly connected to the locking element in the form of a pin, a bolt, etc. or with a leading to the locking element drive rod. The positioning and the type of connection are irrelevant, as long as a change in position of the locking element causes a corresponding change in position of the fitting position sensor, magnetic sensor or the additional magnetic sensor. For easier coupling of the actuator to the locking element, the actuator may have a suspension opening, the size and shape of which allows hooking into a locking pin or locking bolt. The actuator provided with the fitting position sensor or the magnetic sensor and / or additional magnet can in particular be adjustably mounted in and protrude from an elongate housing of the assembly in which the additional magnet is arranged, wherein the free end is movably connected to the locking element. The monitoring arrangement is thereby combined to form a structural unit except for the magnet, which is fastened to the fixed frame, and as such can be mounted preassembled in a corresponding position on the wing.

The actuator may additionally be biased by at least one spring element in its entire adjustment range to train, so it must transmit pressure forces in any operating condition. The risk of buckling is thereby avoided and the actuator can also be designed with small, slim cross-sections. Thus, for example, it can be pulled out of the housing against the force of a spring and thus occupy the various, defined positions corresponding to the locking element.

According to a further claim, the magnetic sensor can have a distance from the magnet in the case of tilt-turn wings, as frequently used in conventional windows or patio doors, or in the case of tilting wings, such as those used in skylights above door leaves, in a tilted position of the wing. which is smaller than the limit value for triggering the switching operation, whereby the tilted position of a wing can be monitored as a locked state, since the locking element is not in the unlocked position, which is provided for pivotally opening a wing. Thus, with only one magnetic sensor, it is possible to monitor both the completely closed state and the tilted state of the blade for possible penetration attempts, which is advantageous because the blades are often in the tilted position and in many conventional systems either in the tilted position Monitoring is carried out or can only be monitored by the use of their own magnetic sensors for the closed state and each for the tilted state. Reed contact switches which are available in many different sensitivities and are distinguished by high reliability can advantageously be used as magnetic sensors.

In order to prevent manipulation of the magnetic sensor by approaching a disturbing magnet, the monitoring device may comprise a disturbance magnet sensor which is arranged outside the range of action of the magnet and the additional magnet and triggers a switching operation when an interference magnetic field occurs, which acts on a signal generator or an alarm system , The interference magnet sensor is preferably designed as a reed contact switch and closer and connected in parallel to the magnetic sensor.

The monitoring arrangement, together with a battery and an acoustic signal transmitter, which are connected to the magnetic sensor and optionally connected in series with this additional magnetic sensor connected to a circuit to be added to a structurally simple, independent and decentralized alarm system, which is particularly suitable for a Retrofitting existing components is suitable.

Furthermore, the Beschlagstellungs-sensor or the magnetic sensor and optionally connected in series to this additional magnetic sensor may be connected to an electronic unit, which forwards a switching signal after a, in particular adjustable delay to a signal generator or alarm system. This can be prevented, that at intermediate positions of the locking element and thus at short time inaccurate positioning of the magnetic sensor relative to the additional magnet equal false alarm is triggered, as might occur, for example, in a slow actuation of the fitting.

Another embodiment, wherein the magnetic sensor is connected to a battery for powering the monitoring arrangement and in a switching operation of the magnetic sensor, the battery is connected to a voltage monitoring arrangement, which is coupled to the signal generator or the alarm system. Increases the reliability of a monitoring arrangement according to the invention for the case that the power supply takes place by means of a battery, which, as described above, requires a low installation effort. The invention further relates to a component in the form of a window or a door, which is equipped with a monitoring device according to the invention, which is arranged between the frame and the wing of the component. The arrangement in the fold, the monitoring device from the outside is generally not accessible or very difficult to access, making it difficult to manipulate it.

The use of openers as magnetic sensors and thereby a normally open circuit that is closed in an intrusion attempt, is also advantageous that a severing of the connection cable also causes a circuit closure or can easily cause and therefore takes place an alarm triggering.

In a turn-tilt wing or tilt wing of a window or a door, it is advantageous if the monitoring device is disposed in the fold axis adjacent and parallel to the fold, since in this case both the locked wing and the tilted wing can be secured with only a monitoring device against violent intrusion. In most cases, this means that the monitoring device is placed in the lower, horizontal fold between the frame and the sash.

An inventive component may further comprise an electronic unit which is connected to the magnetic sensor and arranged in the fold between the frame and the wing, the electronic unit serves, after triggering a switching operation, an alarm signal with a preferably adjustable minimum duration to a signal generator or a potential-free closing contact or Forward opening contact to an alarm center. The minimum duration ensures that the alarm is triggered or a permanent alarm signal is issued even after an attempt to break in immediately stops, thereby alerting the surroundings when the wing is immediately approaching the frame once a break-in attempt has been stopped. The electronic unit can for example act so that a switching signal of the magnetic sensor 15 in the armed state activates an acoustic signal transmitter for a certain period of time eg several minutes and / or a switching signal from short duration to a few seconds to an alarm system control forwards such as to a potential-free contact such , For a better understanding of the invention, this will be explained in more detail with reference to the following figures.

By way of introduction, it should be noted that in the differently described embodiments, the same parts are provided with the same reference numerals or the same component names, wherein the disclosures contained in the entire description can be mutatis mutandis to the same parts with the same reference numerals or component names. Also, the location information chosen in the description, such as top, bottom, side, etc. related to the immediately described and illustrated figure and are to be transferred to the new situation mutatis mutandis when a change in position. Furthermore, individual features or combinations of features from the different exemplary embodiments shown and described can also represent independent, inventive or inventive solutions.

All statements on ranges of values in objective description are to be understood as including any and all sub-ranges thereof, eg the indication 1 to 10 should be understood to include all sub-ranges, starting from the lower limit 1 and the upper limit 10 ie all subareas begin with a lower one Limit of 1 or greater and end at an upper limit of 10 or less, eg 1 to 1.7, or 3.2 to 8.1 or 5.5 to 10.

Fig. 1 shows a view of a device according to the invention 1, here in the form of a window 2. The component 1 comprises a fixed frame 3, which is installed in a masonry, not shown, and a relative to the frame 3 adjustable wings 4, in the illustrated Embodiment designed as a turn-tilt wing, but can also be designed as a simple rotary wing or simple tilt wing. The wing 4 can be adjusted relative to the frame 3 about a vertical axis of rotation 5 or alternatively about a horizontal tilt axis 6. The wing 4 is hinged with a locking fitting 7 on the frame 3 adjustable and lockable, wherein the locking fitting 7 a plurality of hinges 8 for the adjustability and at least one latch 9, with which the wing 4 can be fixed to the frame 3 comprises. The lock 9 comprises an adjustable locking element and a fixed locking piece. It is further also possible that a hinge 8 is also used as a lock when it is used both for the production of mobility between the wing 4 and frame 3 at the same time, as well as for locking.

The operation of the locking fitting 7, for example, with an operating handle 10, with which the required for the desired function of the wing 4 fitting parts in the form of hinges 8 and 9 locks are activated or deactivated. For example, in the case of the right-hinged leaf 4 shown in FIG. 1, the two right superimposed hinges 8 are activated for the rotational opening of the wing 4 with respect to the vertical axis of rotation 5, while the left, lower hinge 8 and the locking 9 are deactivated become. On the other hand, to tilt the wing 4 with respect to the horizontal tilting axis 6, the right, upper hinge 8 is deactivated, while the two lower hinges 8 are activated. The left lower lock 9 can remain in the locked position when tilting the illustrated wing 4, since it is located approximately in the region of the horizontal tilting axis 6 and does not block the tilting movement.

To activate the respective wing function of the operating handle 10, as is common in most cases, between a locking position shown in full line 11 for locking the wing 4, an unlocking position 12, in which the wing with respect to vertika- len pivot axis 5 is pivoted and a tilting position 13, in which the wing 4 with respect to the lower horizontal tilting axis 6 from the frame 3 is pivoted away, be selected.

The component 1 further comprises a monitoring device 14, with which an unauthorized, violent intrusion is monitored by the position of the wing 4 in the locked state and in the tilted state, while in unlocked, open position corresponding to the unlocked position 12 of the operating handle 10 is no monitoring. This quasi-selective arming of the monitoring assembly 14 is achieved in that it comprises a known magnetic sensor 15 on the adjustable wing 4 and a known magnet 16 on the fixed frame 3 and additionally on the wing 4 includes an additional magnet 17 to which the magnetic sensor 15th When the actuating handle 10 is moved into the unlocking position 12, this additional magnet 17 maintains or replaces the magnetic field acting on the magnetic sensor 15 in the closed state by the magnet 16 in the open state of the wing 4 and thereby suppresses the monitoring arrangement 14 in FIG Unlocked position 12 corresponding unlocking position 12 'of the lock 9 is disarmed, whereby during normal opening of the wing 4 no alarm is triggered.

The positioning of the magnetic sensor 15 which can be adjusted on the wing 4 is effected by a movement coupling to a locking element 18 of the lock 9, wherein the adjustment possibility is indicated by a double arrow 19. The magnetic sensor 15 is in the locked or tilted state of the wing 4 in the effective range of the magnetic field of the magnet 16 and is selected by its sensitivity so that an increase in the distance between the magnetic sensor 15 and magnet 16 beyond a threshold beyond a scarf t-operation of the magnetic sensor 15 triggers. By increasing the distance, the magnetic field strength acting on the magnetic sensor 15 decreases, which is detected by the magnetic sensor 15, thereby triggering a switching signal. If the wing is in locked or tilted condition, any increase in this distance is equivalent to a break-in attempt and in this case an alarm is triggered. However, if the wing is unlocked by moving the operating handle 10 into the unlocking position 12 and the locking element 18 is moved into the unlocked position, the magnetic sensor 15 is at the same time approximated to the additional magnet 17, which, as well as the magnetic sensor 15 is attached to the wing 4, with his Magnetic field, regardless of the position of the Wing 4 acts on the magnetic sensor 15 and thereby no switching is triggered at this.

As a result of this arrangement of the magnetic sensor 15 and the movement coupling with the locking element 18, the position of the locked or tilted wing 4 can be monitored with only one magnetic sensor 15, and the unlocking position of the locking element 18 can be sensibly interrogated and linked without any further need for a logic element become. The monitoring arrangement 14 can be used together with its own power supply by a battery and a signal generator as an independent, decentralized alarm system, but can also be connected to an alarm system which protects, for example, a plurality of such components or an entire object.

2 shows a schematic view of the interaction of the components of a monitoring arrangement 14, as can be used in a component 1 according to FIG. 1. The illustrated arrangement of the components is not consistent with the actual structure, but is merely for ease of understanding. For example, the parts arranged on the frame 3 are arranged in the installed state in alignment with the parts arranged on the wing 4. The partially illustrated frame 3 is a part of the lock 9 a

Locking piece 20 attached, which cooperates with a wing 4 adjustable mounted locking element 18, here in the form of a locking pin 21. The locking element 18 is connected approximately via a drive rod 22 and deflecting elements, not shown, with the actuating handle 10 and can correspond to the respective position of the actuating handle 10, either a locking position 11 ', an unlocked position

As can easily be seen, the locking element 18 can emerge only in the unlocked position 12 'from the locking recess 23 of the closing piece 20, as it is when opening the wing 4 with respect the vertical axis of rotation 5 is required. On the other hand, in the locking position 11 'and in the tilting position 13', a leakage of the locking element 18 from the striker 20 transversely to the double arrow 19 is not possible and also not desirable. The monitoring arrangement 14 is now constructed in such a way that a magnet 16 in the form of a permanent magnet 24 is arranged on the stationary frame 3 and a magnetic sensor 15, here in the form of a reed contact switch 25, is coupled to the locking element 18 adjacently thereto on the adjustable wing 4 is arranged. The magnet 16 in this case has a length in the direction of the double arrow 19 which ensures that over the entire adjustment range of the magnetic sensor 15, which coincides in the simplest case with the adjustment range of the locking element 18, permanently, the magnetic field acts on the magnetic sensor 15 and no longer Switching signal is triggered at the magnetic sensor 15 until a distance

26 between the magnet 16 and the magnetic sensor 15 exceeds a certain limit. This change in the distance 26 also causes a change in the

Magnetic sensor 15 acting magnetic field strength of the magnet 16 and this can occur in a violent intrusion attempt enlargement of the distance 26 are used as alarm triggering event, as it is known per se from the prior art. However, so that in the conventional opening of the wing 4, ie in the unlocking position 12 'of the locking element 18 no alarm is triggered, in the corresponding unlocking position 12 "of the magnetic sensor 15, an additional magnet 17 is arranged, with its magnetic field only in the unlocked position 12" of the magnetic sensor 15 acts on this and this thereby also when opening the wing 4 and an increase of the distance 26 to the magnet 16 beyond the limit beyond a switching process performs.

The movement coupling of the magnetic sensor 15 with the locking element 18 takes place for example via a strip-shaped actuator 27 which is connected to the locking element 18 or the same effect with the drive rod 22. This can, for example, as shown, take place in that the actuator 27 has a suspension opening 28, with which it can be hung on the locking pin 21. Thus, the movement of the locking element 18 and the locking pin 21 as possible without play on the actuator

27 and the magnetic sensor 15 is transmitted, the actuator 27 is additionally biased against the locking element 18 with a spring element 29, here in the form of a tension spring 30. In particular, the actuator 27 is biased by the spring element 29 over the entire displacement of the locking element 18 to train, whereby it does not have to transmit compressive forces and therefore there is no risk of buckling, even with very thin cross-section. The magnetic sensor 15 and the additional magnet 17 and the spring element 29 are combined in a flat housing 31, for example made of plastic, which does not shield for magnetic rays, combined to form a structural unit and projects the strip-shaped actuator 27 from this housing with a free end. Due to the compact and flat design of the housing 31 and the monitoring assembly 14 this can be installed protected in the fold between the frame 3 and 4 wings.

The assembly of the monitoring arrangement 14 may be such that the actuator 27 is hooked with its insertion opening 28 on the locking element 18, which is in unlocking position 12 ", and by pulling the housing 31 against the spring force of the spring element 29 of the additional magnet 17 with the magnetic sensor 15th The housing is then secured in this position with fastening means 32, for example in the form of fastening screws, on the wing 4. The correct positioning of the magnetic sensor 15 with respect to the additional magnet 17 can be achieved by a marking on the actuator 27 in the form of a notch or a small hole 33 marked and thereby be relieved.

The poles of the magnetic sensor 15 are led out via a flexible cable and an adjoining connecting cable 34 from the housing 31 and connected to a power source, not shown, and a signal generator, or also connected to a controller of an alarm system.

In order to prevent attempts to manipulate the magnetic sensor 15 with a disturbing magnet from the outside, parallel to the magnetic sensor 15, a perturbation magnetic sensor 35 may be provided, which is arranged outside the effective range of the magnet 16 and additional magnet 17 and thereby not excited by these switching signals is, however, allows detection of magnetic fields emanating from a perturbation magnet. The interference magnet sensor 35 is connected, for example, parallel to the magnetic sensor, which is why an occurrence of a disturbance magnetic field triggers the same alarm as a mechanical intrusion attempt.

The magnetic sensor 15 in the form of a reed contact switch is preferably designed as a so-called opener, which interrupts a circuit between its terminals in the presence of a magnetic field, whereby in all normal operating conditions, in which the magnetic sensor 15 is in the range of influence of either the magnet 16 or the auxiliary magnet 17, no current flows in the monitoring arrangement and therefore a current source in the form of a battery has a very long standby duration. The interference magnet sensor 35 is preferably also designed as a reed contact switch, but as a so-called NO contact, which closes a circuit when exposed to a magnetic field.

As further indicated by dashed lines in FIG. 2, the individual magnet 16 may also be replaced by two spaced-apart magnets 36 and 37, which also in the locking position 11 "and in the tilt position 13" of the magnetic sensor 15 for monitoring the Distance 26 radiate suitable magnetic field.

Magnet 16 and additional magnet 17 may be formed in particular by permanent magnets of so-called rare earth metals such as neodymium, which generate a high magnetic field strength and therefore can be used in small dimensions, and therefore for installation in the rebate between the frame 3 and window 4 are particularly suitable.

Fig. 3 shows the monitoring assembly 14 in a side view motion coupled with a locking member 18 in the form of a locking pin 21. This is connected by means of the drive rod 22 with the actuating handle, not shown, and in the direction of the double arrow 19, starting from the illustrated unlocking position 12 'to the left in the locking position 11 'and to the right in the tilted position 13' adjustable (see Fig. 2). The drive rod 22 is usually behind a cover plate 38, which is also referred to as Stülp, arranged protected and protrudes only the locking element 18 in the fold between the wing 4 and the frame located below 3. To avoid repetition, is based on the descriptions of Components with the same reference numerals in Fig. 2 referenced.

4 shows an alternative embodiment of a monitoring arrangement 14 with which the locked and possibly also the tilted state of a wing 4 can be monitored for forced entry. In this embodiment of the monitoring arrangement 14, a distance 26 is also monitored between the magnetic sensor 15 arranged on the wing 4 and the magnet 16 arranged on the frame 3, thereby preventing the triggering of an alarm in the unlocking position 12 'of the locking element 18 is that to the magnetic sensor 15, a Zuatzmagnetsensor 39 is connected in series and this is so coupled with the locking element 18, that it is positioned in the defined unlocked position 12 'adjacent to the fixed to the wing 4 additional magnet 17.

The operation of this embodiment of a monitoring assembly 14 substantially corresponds to that of the embodiment described with reference to FIGS. 1 to 3, by the movement of the operating handle 10 in the unlocked position 12 is not spent here but the magnetic sensor 15 in the vicinity of the additional magnet 17, but with a this in series connected additional magnetic sensor 39, which in the corresponding unlocked position 12 'of the locking element 18 of the corresponding unlocked position 12 "spent magnetic sensor 15 is also quasi disarmed, since its switching signal is suppressed by the auxiliary magnetic sensor 39 designed as a normally closed 10, however, the locking element 18 in the locking position 11 'or the tilted position 13' is adjusted, thereby the additional magnetic sensor 39 is displaced out of the magnetic field of the additional magnet 17, whereby it closes its contacts and thereby the magnetic sensor 15 detecting the opening state of the vane 4 is armed. In the other components provided with reference numerals of the embodiment of FIG. 4 reference is made to avoid repetition to the description of the components provided with the same reference numerals in Fig. 1 to Fig. 3. The poles of the additional magnetic sensor 39, which is coupled in a motion with the locking element 18, are guided via flexible lines or cables to the magnetic sensor 15 or to the connecting cable 34.

The embodiments of a monitoring arrangement 14 shown in FIGS. 2 and 4 show an assembly 40 which is suitable for easy, in particular retrofitting, mounting in FIG. 2 the magnetic sensor 15 and the additional magnet 17 or in FIG. 4 the magnetic sensor 15 Additional magnet 17 and the additional magnetic sensor 39 includes.

5 shows a view of an alternative embodiment of a monitoring arrangement 14, with which a forced opening of a component 1 can likewise be monitored.

In the case of component 1, a hill 4 is again mounted so as to be adjustable relative to a stationary frame 3 and can be fixed to the frame 3 by means of a locking fitting 7. In this case, as in previous embodiments, a locking element 18, for example in the form of a locking pin 21 by means of a drive rod 22 relative to a fixed to the frame 3 closing piece 20 adjustable on the wing 4 and the locking member 18 can be adjustable at least between a locking position 11 and an unlocking position 12 , wherein prior to a normal opening of the component 1, the locking element 18 is moved into the unlocked position 12. In addition, as in the illustrated embodiment, a tilting position 13 may be provided, as is the case with turn-tilt windows. The monitoring of the opening of the wing 4 is carried out as in the previous embodiments by detecting a distance 26 between a fixed to the frame 3 magnet 16 and a wing 4 fixed magnetic sensor 15, which is designed as a reed contact switch. This monitoring of the distance is linked to a detection of the position of the locking element 18 by the magnetic sensor 15 and a Beschlagstellungs- sensor 41 are connected to an evaluation unit 42.

The magnetic sensor 15 is designed as a so-called opener, which assumes an open switching position under the influence of the magnetic field of the magnet 16, ie at a voltage applied to the frame 3 closed wing 4 and closes a contact with increasing the distance 26 beyond a limit. By using a magnetic sensor 15 in the form of an opener, it is possible to activate the evaluation unit 42 only when opening the wing 4 by a switching operation of the magnetic sensor 15, for example by being connected to a battery 43. After activation of the evaluation unit 42, the latter performs a query as to whether the fitting position sensor 41 has detected an unlocking position 12 or a locking position 11 or a tilting position 13 of the locking element 18, and activates only in the presence of a locking position 11 or the tilting position 13, ie at a Forcibly open a signal generator or alarm system, which takes place for example via a connecting cable 34.

The fitting position sensor 41 can act as described with reference to previously described embodiments in that an additional magnetic sensor or a magnet with the adjustable base Ren locking element 18 is coupled and thereby, for example, a circuit is opened or closed. After this evaluation of the Beschlagstellungssensors 41, the evaluation unit 42, if the unlocked position 12 has been detected, again go into a sleep state or standby state in which no or only a negligible power consumption takes place.

The advantage of this embodiment of a monitoring arrangement 14 is again in the battery-saving design, since in the normal closed state, the evaluation unit 42 manages with a very low or even without supply voltage. When lithium batteries are used, such a monitoring arrangement 14 can remain operational for several years, even over 10 years.

In order to further increase the reliability of such a monitoring system 14, a voltage monitoring arrangement 44 may be provided, which may be a part of the evaluation unit 42 or an independent component and which performs a short measuring routine for detecting the battery voltage after each switching operation of the magnetic sensor 15. In this case, it can be provided that, if the battery voltage is sufficient, a short confirmation signal is output which signals the functionality of the monitoring arrangement 14 to the user by means of a signal transmitter or a status message on an alarm system. If the voltage of the battery 43 has fallen below a limit value, the user is signaled by a changed signal, for example by a continuous tone on the signal generator or the alarm system. The measuring routine for the battery voltage monitoring arrangement 44 thus provides the user with information on the state that the turntable 14 is operational when the wing is opened normally In this case, an alarm is triggered anyway.
