Abstract

A securing device for securing the wing of a window, door or the like against impermissible opening is designed to detect a state of the wing, which can be in a closed state or in an open state, and to detect a position of a fitting assembly of the wing, which can be moved between an unlocking position and one or more locking positions, wherein the wing can be opened completely, in particular opened by rotation when the fitting assembly is in the unlocking position, and the wing can be opened only to a limited extent, in particular opened by tilting, or is prevented from opening when the fitting assembly is in one of the locking positions. The securing device is also designed to output a state signal, in particular to an alarm device, according to both the detected state of the wing and the detected position of the fitting assembly.

Description

FUSE DEVICE FOR MONITORING THE POSITION OF A WING

The present invention relates to a safety device for securing the sash of a window, a door or the like against improper opening.

The wing of a window, a door or the like can be secured, inter alia, against unauthorized opening, that in the event of an inadmissible opening, an alarm is triggered. For this purpose, an alarm device may be provided. In particular, an alarm may comprise an optical and / or audible signal emitted in the event of an alarm at or near the point of unauthorized opening, in order to have a deterrent effect and to alert people to the unauthorized opening. However, an alarm may additionally or alternatively also include the transmission of an alarm signal to a remote entity, eg: to the police and / or a security service. In addition, it can be provided that suitable defense measures are initiated in response to the alarm, preferably automatically. In order for an alarm to be triggered in the event of an inadmissible opening, it is necessary to be able to detect an opening of the sash at all and preferably also be able to determine whether it is an inadmissible opening or not. A safety device for securing the sash is therefore advantageously designed to detect a respective state of the sash, wherein a closed state of the sash is to be distinguished from an open state of the sash. The closed state and the open state are not necessarily fixed to concrete positions of the wing. Rather, it can become the wings are in various positions in the closed state and in various other positions in the open state.

The closed state preferably comprises such positions of the wing in which penetration through the respective window or the respective door is not possible, and the open state includes those positions of the wing in which penetration is possible. For example, in a wing that is both rotatable and tiltable, the closed state may include the fully closed position as well as all tilt open positions of the wing, provided that the latter does not allow easy entry through the respective window or door. The open state can then include all others, ie in particular all rotationally open positions. However, in the case of a turnable and tiltable sash, the tilted open positions can also be assigned to the open state. In this case, the closed state may in particular comprise only the fully closed position of the wing. If it can be detected by means of the securing device whether the wing is in the open state or in the closed state, an opening can be recognized by the fact that the open state is detected after the closed state of the wing was previously detected.

Furthermore, the safety device can be designed to output a respective state signal in dependence on the detected respective state of the wing. In this case, a respective state signal may also depend on a detected respective state of the wing insofar as it depends on a respective change of the state, for example by taking into account one or more previously detected respective states in addition to the respectively last detected respective state of the wing.

The respective status signal can in particular be output to an alarm device, which then, for example, as described above, depending on the reception genem condition signal can trigger an alarm. Typically, such an alarm device is provided separately from the security device. For example, the alarm device may be provided at a central location within a building, especially when the alarm device is a central unit of an alarm system. In particular, when the alarm device is an alarm siren, a location from which the alarm is widely audible may be advantageous. In principle, however, it can also be provided that the alarm device is integrally formed with the securing device. Typically, not in all cases in which by means of the safety device on the basis of the detected respective state of the wing opening of the wing is detected, an alarm should also be triggered. Because not every opening of a window or a door represents an inadmissible opening. For alarm devices, it is known that they can therefore optionally, in particular manually, be activated and deactivated. This makes it possible that a detected opening of the wing triggers an alarm only when the alarm device is armed, ie activated. Consequently, by simply disabling the alarm device, and possibly also by deactivating the security device, it can be prevented that a regular opening triggers an alarm. This assumes, however, that deactivation is not forgotten before opening the sash. Otherwise, a false alarm is triggered.

However, if the safety device or a downstream alarm device has been deactivated, for example, for a permissible opening of the sash, it is important that it is thought of the safety device or the

Alarm again after closing the sash. Otherwise, the wing can then be opened in an inadmissible manner without this being detected by the security device or receiving a corresponding status signal from the alarm device. The reliability of the safety of the sash in such a system is therefore also dependent on the attention of the respective user. The fact that the user also has to consider when opening and closing the wing, whether the backup device and / or the alarm device is activated, and they may need to enable or disable, comfort is also impaired.

It is an object of the invention to provide a safety device for securing the sash of a window, a door or the like, a fitting arrangement with such a safety device and a method for securing the sash, which offer improved reliability and improved comfort.

The object is achieved by a securing device with the features of claim 1, by a fitting arrangement with the features of claim 17 and by a method having the features of claim 18. Preferred embodiments of the securing device, the fitting arrangement and the method emerge from the subclaims , the present description and the drawings.

The securing device according to the invention is in particular designed to detect, in addition to the respective state of the wing, also a respective position of a fitting arrangement of the wing, which is adjustable between an unlocking position and one or more locking positions, wherein the wing is completely apparent, in particular rotatable, if the Unlocked position of the fitting assembly is present, and wherein the wing only limited apparent, for example, tiltable open, or is locked against opening when one of the locking positions of the fitting assembly is present.

In other words, the securing device can not only distinguish the state of the wing between the open state and the closed state, but in particular simultaneously, but at least in a timely manner, detect what position the Fitting arrangement of the wing occupies. The respective position of the fitting arrangement can then be used in particular as a criterion for whether a detected opening of the wing has occurred in a permissible or impermissible manner. For if the fitting arrangement is currently in any of its locking positions in which the wing can not actually be fully opened, but opening of the wing is detected by means of a transition from the closed state to the open state, this can be taken as a clear indication be that the opening is inadmissible, in particular bypassing locking means such as the fitting arrangement occurred. Conversely, an impermissible opening of the wing can be excluded by detecting the unlocking of the fitting assembly, since the wing is already fully apparent in the presence of unlocking anyway.

It is therefore advantageous to take into account the respective position of the fitting arrangement in addition to the respective state of the wing, in particular with regard to the triggering of an alarm. For this purpose, the securing device is further adapted to output the respective status signal not only in dependence on the detected respective state of the wing, but in additional dependence on the respective position of the fitting arrangement. If the respective position of the fitting arrangement and the respective state of the wing are not detected at the same time, the respective state signal is preferably dependent on the last detected state of the wing and the respectively last detected position of the fitting arrangement. In this case, depending on the respective state of the wing and / or on the respective position of the fitting arrangement, it may depend in particular on whether a respective status signal is output at all and / or what content the respective status signal has.

The additional detection of the position of the fitting arrangement and its consideration in the output state signal can in particular be an activation or deactivation of the safety device or an alarm device, which receives the status signal and if necessary respond to it, make unnecessary. Because it no longer needs to be set manually by activating or deactivating when an opening of the sash leads to an alarm and when not. Instead, by deactivating the fitting arrangement into the unlocking position, the securing device or the alarm device can be deactivated as it were. Conversely, the securing device or the alarm device is automatically activated by offsetting the fitting arrangement in one of the locking positions. A real activation or deactivation need not be done at all. Because it may be sufficient to be able to distinguish a permissible from an impermissible opening of the wing based on the respective state signal.

The comfort in the operation of a secured with a security device invention wing of a window, a door or the like is improved because when opening and closing of the wing only in the usual way, the fitting assembly must be operated, but not additionally the activation or deactivation of the security device or the alarm device must be considered. Therefore, such activation or deactivation can not be forgotten, so that false alarms can be avoided and the security device or the alarm device can basically remain active throughout. In this way, the safety device contributes to an improved reliability of the safety of the wing.

The security device can in particular be designed to cooperate with known alarm devices or entire alarm systems, in particular, at least in the transmission direction, to be in communication connection, so that respective state signals can be transmitted from the security device. Preferably, the signal transmission takes place by radio. This allows a simple spatial separation of the security device from the respective alarm device or from the respective alarm system as well as a easy retrofitting. In this respect, the security device can also be regarded as a sensor within a larger alarm system, which may include a plurality of further sensors for detecting respective other, in particular safety-relevant, parameters. One or more common protocols can be supported for the communication connection in order to be flexibly compatible with different systems.

The respective status signal can basically be output continuously by the security device. However, it may also be sufficient if the safety device outputs respective state signals discontinuously in time. For example, the status signal can be output at regular time intervals or according to a predetermined or predefinable time pattern. Furthermore, provision may be made for the status signal to be output additionally or only in each case when there has been any change in the state of the wing and / or the position of the fitting arrangement, or in each case when a change has resulted which corresponds to an inadmissible opening , Alternatively or additionally, it may further be provided that the status signal is output when the security device, e.g. from the alarm device, receives an interrogation signal.

Basically, irrespective of when, how long and how often respective status signals are output, a respective status signal may be a raw signal insofar as it is simply the information about the detected respective state of the wing and the detected respective position of the Be - impact arrangement comprises. For this purpose, in the safety device itself no evaluation must be made to determine which state of the wing or which position occupies the fitting arrangement or whether the respective state or the respective position or a change of state or position gives rise to the triggering of an alarm. In such a passive safety device, the evaluation can be done downstream, such as in an alarm device, which the receives respective status signals from the security device and independently determines on the basis of the state signals, whether an alarm or other reaction is triggered or not. In particular, in connection with such a passive securing device, an embodiment may be preferred in which the securing device is designed to output the respective status signal continuously or repeatedly, in particular regularly.

As an alternative to a passive securing device, it can be provided that an evaluation of the condition of the wing and the position of the fitting arrangement takes place completely or at least partially already in the securing device. For example, it can be provided that the securing device independently determines whether the detected respective state of the wing and the detected respective position of the fitting arrangement indicate the presence of an irregular state, to which then in particular would respond by means of an alarm. In such an embodiment, the security device may be configured to emit a particular signal in the case of a condition judged to be irregular, and otherwise to send out no or other specific signal. From a downstream device, which receives the respective state signals, the respective state signal need not be further evaluated, but it is sufficient if it is reacted to the respective state signal in a suitable manner.

According to one embodiment, the security device is designed to output the respective state signal only when the open state of the wing is present. If the condition of the wing is not detected continuously, the most recently detected condition of the wing is decisive. In such an embodiment, therefore, no status signal is output in the closed state of the wing. This can be dispensable, as an inadmissible opening of the wing can not have taken place anyway, as long as the wing is in the closed state. According to another embodiment, the securing device is designed to output the respective status signal only if one of the locking positions of the fitting arrangement is present. In this embodiment, therefore, no status signal is output when the fitting assembly is in the unlocked position. This can be dispensable, since the wing is not locked in the unlocked position of the fitting arrangement anyway against a complete opening, so that no inadmissible opening can take place. Particularly preferred is a combination of the two preceding embodiments, in which therefore the securing device is designed to output the respective status signal only when the open state of the wing is present and also if one of the locking positions of the fitting arrangement is present. Because if the fitting arrangement is in a locked position, the wing should not actually be allowed to open. Therefore, if in a locking position of the fitting arrangement the open state of the wing is detected, this is an indication that an inadmissible opening of the wing has occurred. Since in this embodiment, the respective state signal is output only in this case, the state signal corresponds to an alarm signal, which then need not be further evaluated. Because that the state signal is sent out at all, then is sufficient as an indication already to determine that the wing was opened in an inadmissible manner, and if necessary to respond with an alarm. As an alternative to such an embodiment, just the opposite, the absence of a signal can be interpreted as an indication that an irregular state, in particular an impermissible opening of the wing, is present, whereas the mere presence of a signal can then be regarded as a sign of a regular state , Such an embodiment may be advantageous insofar as a failure of the security device, eg in case of damage, is emptied Batteries or a power interruption, then does not appear as a regular state, but can be recognized as an irregular state.

In this context, an embodiment may be advantageous in which the securing device is designed to output the respective status signal only when the closed state of the wing is present and / or the unlocking position of the fitting arrangement is present. Thus, if either the closed state of the wing is present and the wing is therefore not opened at all, or if the unlocking position of the fitting arrangement is present and the wing is therefore already completely fully visible anyway or if both are the case, a respective status signal is output which is insofar as a warning - Signal can be understood, which signals a regular state.

In this embodiment, furthermore, preferably no respective status signal is output when the open state is present and at the same time one of the locking positions of the fitting arrangement is present, that is to say, in each case at least last detected. In such an embodiment, an alarm may then be triggered in response to a failure of the status signal. According to a further advantageous embodiment, the security device is designed to output the respective state signal in response to a received interrogation signal. In particular, it may be provided that the respective status signal is output only when the security device has previously received an interrogation signal. However, a transmission of a respective status signal triggered by a query can also be supplementary to a regular transmission of respective status signals and / or automatic transmission of respective status signals, for example, if respective status signals are otherwise emitted when a change in the state of the wing and / or the position the fitting arrangement was detected. Such an external requesting of a status signal may be particularly useful in embodiments in which a respective status signal is otherwise transmitted only when an irregular state has been detected, ie when in particular the open state of the wing and at the same time one of the locking positions of the fitting arrangement. In such an embodiment, the absence of the status signal can therefore be regarded as a sign that everything is in order. A failure of the security device could then lead to an irregular state being incorrectly not recognized as such, since the respective state signal is missing, although it would have to be sent out. Therefore, it may be useful if an external device, such as an alarm device, occasionally or regularly, requests a respective status signal to check the operability of the security device. If the status signal remains in spite of the query, a failure of the security device can be detected.

In the above embodiments, the securing device itself need not be configured to evaluate whether a regular or an irregular state exists based on the detected state of the wing and the detected position of the fitting assembly. Rather, in these embodiments it may be sufficient if the output respective state signal contains both information in such a way that a device receiving the respective state signal can carry out the evaluation. Such security devices need in this respect have no logic or logic that only decides whether ever a respective status signal is sent out. However, an evaluation can also be made entirely or partially by the security device itself.

According to an advantageous embodiment, provision is made for a status signal output by the security device to be a regular signal or a regular signal Irregular signal, in particular only either a regular signal or an irregular signal, may be, wherein preferably exactly one regular signal and exactly one irregular signal are provided. If this is the case, in other words, the security device can only ever output two different signals. Which of these two signals is output as the respective state signal, then still depends both on the (last) detected state of the wing and the (last respectively) detected position of the fitting arrangement. However, it may be that it is not possible to unambiguously deduce from the output signal which state of the blade exists and which position of the fitting arrangement is present. This need not be necessary, since the evaluation of whether this combination of the state of the wing and the position of the fitting arrangement corresponds to a regular or an irregular state may already have been effected by the securing device. As a result of this evaluation, either the regular signal or the irregular signal is emitted accordingly. It is signaled by the regular signal that everything is OK, without it should be apparent, in which position the fitting arrangement is or whether the wing is open or closed. The irregular signal indicates that an irregular state is present, in particular that the wing has been opened inadmissibly, again without it having to be apparent in which position the fitting arrangement is or whether the wing is open or closed. The irregular signal may be interpreted as an alarm signal in response to which, for example, an alarm may trigger an alarm.

In principle, however, it may also be that more than one regular signal and / or more than one irregular signal are provided, of which the safety device emits one each as a respective status signal. For example, it is possible to distinguish between two irregular signals, one of which is sent out when the wing's open state is present and at the same time one of latching positions of the fitting arrangement is present, and is therefore to be regarded as an alarm signal, and of which the other is emitted approximately at a low battery level or a detected other existing or imminent impairment of the safety device and is therefore to be regarded as an error signal.

According to an advantageous development, the securing device is designed to output a regular signal, in particular only when the closed state of the wing is present and / or the unlocking position of the fitting arrangement is present. For issuing a regular signal, it is not absolutely necessary for both conditions to be met, since one of the conditions can already be used to rule out unauthorized opening of the sash. In principle, however, it may be provided that one or more additional conditions must be fulfilled for the output of a regular signal.

Alternatively, but preferably in addition to the above design, the securing device can advantageously be designed to then output an irregular signal, in particular only when the open state of the blade is present and one of the locking positions of the fitting arrangement is present. In this way, in the case of an impermissible opening of the wing, in which the fitting arrangement has not been previously set in the unlocked position, reliably an irregular signal is output to which can then be reacted in a suitable manner. Regardless of what is sent for each state signals, the securing device is designed according to a further embodiment, for detecting the position of the fitting arrangement to detect a position of a transmission, a drive rod or arranged thereon element of the fitting assembly. For example, the securing device may comprise a sensor or be designed as a sensor which is provided on the transmission, which is typically effective between a handle and a drive rod of the fitting assembly to divert actuations of the handle to displace the drive rod and thus, in particular, dislocate lock pins provided on the drive rod. However, the detection of the position of the fitting arrangement can also take place directly on the drive rod or an element connected to it for common movement, such as the mentioned locking pin. The locking pin does not necessarily have to be a pin, which also interacts concretely for locking the blade with a closing part. Rather, the pin can also be borrowed borrowed in the manner of such a locking pin.

According to a preferred embodiment, the securing device comprises at least one or more distance-dependent switching devices, in particular for the unlocking position and for each of the locking positions of the fitting arrangement depending on a distance-dependent switching device, in particular in the manner of a reed contact to detect the respective position of the fitting assembly. The movement of respective elements of the fitting arrangement is typically narrow and only one-dimensional, ie only along a path (back and forth) possible. Therefore, can be suitable for detecting the respective position of the fitting arrangement distance-dependent switching devices, which are arranged in particular along said movement path of a respective element, with which they cooperate. For this purpose, a distance-dependent switching device is preferably arranged such that the respective element interacting with it moves relative to the switching device when the position of the fitting arrangement to be detected changes. As a result, the distance to the switching device and consequently its switching state can change, so that the change in position can be recognized by it. As a distance-dependent switching devices are particularly suitable reed contacts, since they can be reliable, cheap, compact and robust. Instead of such magnetic switching devices but switching devices may be provided, the distance dependence is based on a mechanical, electrical or other interaction.

In the simplest case, such as reed contacts, the distance-dependent switching device can occupy exactly two switching states, which can be referred to as closed or switched or open or unswitched. Therefore, a single distance-dependent device can each be limited to detecting whether or not a specific position of the fitting arrangement is present (within the scope of the accuracy or range of the respective switching device). Depending on how exactly the respective position of the fitting arrangement is to be detected, in particular how many different positions of the fitting arrangement can be distinguished, a corresponding number of distance-dependent switching devices can be provided.

Distance-dependent switching devices can advantageously not only be used to detect the respective position of the fitting arrangement, but also the respective state of the wing. Preferably, at least one respective distance-dependent switching device is used to detect both the respective position of the fitting arrangement and the respective state of the wing or in any case contribute to each. This may be possible in particular by suitable arrangement of the respective switching device.

According to an advantageous development, the respective state signal, in particular exclusively, depends on the respective switching states of the distance-dependent switching devices and / or on a change in the respective switching states of the distance-dependent switching devices. In this way, the security device can have a comparatively low complexity. Preferably, each change in the state of the wing or the position of the fitting arrangement leads to a change in the switching state of at least one distance-dependent switching device, so that it can be provided that only when a change in a switching state, an evaluation and / or a respective state signal is emitted.

If the ranges of two distance-dependent switching devices do not overlap, it may happen that in an adjustment of the fitting assembly from a position in which one of these switching devices is switched to another position in which the other switching device is connected, that in between none of these switching devices is, so that under certain circumstances it can not be distinguished whether the fitting arrangement is actually somewhere between the two positions or perhaps there is a very different state. Therefore, it may be provided that when changing a switching state in each case a certain waiting time is first waited and, for example, a decision on whether a regular signal or an irregular signal is sent, takes place only when the respective switching states are known after the grace period. According to a further advantageous embodiment, the securing device comprises a frame part for frame-side arrangement, in particular in the fold of the respective window or door, wherein the frame part has the at least one distance-dependent switching device and is adapted to a arranged on a drive rod of the fitting arrangement element, in - A special locking pin, cooperate to detect the respective position of the fitting assembly. If the element arranged on the drive rod is an element which is not specifically provided for the safety device but, like a lock pin, would otherwise be provided, it may be necessary to use the element for interaction with the device distance-dependent switching device in a suitable manner modify. For example, if it is not already permanently magnetic, the element can be provided with a permanent magnet, which can interact with a switching device designed as a reed contact. According to a preferred development of the preceding embodiment, the securing device comprises a, in particular permanently magnetic, wing part, which is designed to be arranged on the drive rod of the fitting arrangement or on an element arranged thereon, in particular a locking pin, in order to engage with the at least one distance-dependent one Switching device cooperate to detect the respective position of the fitting assembly. In this way, the securing device can be designed such that it can be easily retrofitted to conventional windows or doors. Regardless of whether the securing device comprises such a wing part or can interact with existing elements of the fitting arrangement, it is preferred if the frame part has a plurality, in particular at least three, distance-dependent switching devices whose arrangement respective positions of the element arranged on the drive rod, in particular of the locking pin corresponds, so that at least in the closed state of the wing depending on the respective position of the fitting arrangement, a respective other of the distance-dependent switching devices is switched and the others are not switched, or vice versa, and preferably also in the open state of the wing regardless of the respective position of the fitting arrangement no or all distance-dependent switching devices are connected.

In the case of such a dependence of the respective switching states both on the respective position of the fitting arrangement and on the respective state of the wing, an unambiguous assignment between each occurring combination of switching states is advantageously at least to the respective basis. lying state of the wing and preferably, at least in the closed position of the wing, also possible to the respective underlying position of the fitting arrangement. In this way, with simple switching devices, all information that is required for the evaluation of whether an irregular state is present or not can be detected.

According to a further advantageous embodiment, the securing device is designed as a frame side to be arranged closing part, in which a locking pin of the fitting arrangement engages such that the wing is thereby locked against complete opening, if one of the locking positions of the fitting assembly is present. The safety device then has a double function. It not only serves to detect the respective state of the wing and the respective position of the fitting arrangement and the transmission of a corresponding respective state signal, but also contributes to the locking of the wing to the respective frame. In this respect, it can be provided instead of a conventional closing part. Then, no additional locking pin or other additional element for the interaction with the distance-dependent switching devices needs to be provided on the drive rod. Instead, a locking pin which is provided anyway for engagement in a closing part for locking the wing, which possibly only has to be provided with a permanent magnet, can cooperate with the securing device on the one hand as with an ordinary closing part and on the other hand with the switching devices of the securing device for the Detecting the respective position of the fitting arrangement together act.

The fitting arrangement according to the invention for a window, a door or the like comprises a securing device as described above, which is designed in particular according to one of the embodiments described above. The advantages of such a fitting arrangement correspond to each because at least substantially those of the respective security device and also include that retrofitting an ordinary fitting assembly is not required in each case and that the securing device can be particularly well matched to the rest of the fitting assembly.

In the method according to the invention for securing the sash of a window, a door or the like against inadmissible opening a fitting arrangement is provided which is adjustable between an unlocked position and one or more locking positions, wherein the wing completely apparent, in particular rotatable, is when the unlocked position of Fitting arrangement is present, and wherein the wing only partially limited, especially tiltable open, or is locked against opening when one of the locking positions of the fitting assembly is present. The method comprises that a respective state of the wing, which may be in a closed state or in an open state, and a respective position of the fitting arrangement are detected and that depending on both the detected respective state of the wing and the detected respective position of the fitting arrangement, a respective state signal, in particular to an alarm device, is output.

The advantages of the method according to the invention result in correspondence with those of the securing device according to the invention. In particular, embodiments of the method may be provided which correspond to respective embodiments of the securing device according to the invention.

The invention will be further explained by way of example only with reference to the figures.

Fig. 1 shows an embodiment of a securing device according to the invention in a plan view and a side view. Fig. 2 shows the same embodiment arranged in the fold of a window frame. 3 to 6 show the same embodiment together with a detail of a respective fitting arrangement, which has a pin cooperating with distance-dependent switching devices of the securing device, in different positions of the fitting arrangement.

In Fig. 1, an embodiment of a securing device according to the invention 1 1 in a view from the side (in Fig. 1 above) and a view from above (in Fig. 1 below) is shown. The securing device 1 1 has a flat elongated shape, which makes it possible to arrange the securing device 1 1 in the fold between a window frame 13 of a window or a door and the wing of the window or the door. The attachment of the securing device 1 1 can be effected in particular by screwing the securing device 1 1 on the frame 13, which is shown by way of example in Fig. 2, in which the frame 13 in cross section and the embodiment shown in Fig. 1 of the securing device. 1 1 from the front (which corresponds in Fig. 1 a viewing direction from left to right) is shown.

For screwing, the securing device 1 1 four holes 15, which are provided in a central portion 17 of the securing device 1 1, but in principle may be provided in other numbers at other respective locations. A provided at one end of the longitudinal extension of the securing device 1 1 sensor portion 19 is compared to the middle portion 17, in particular with respect to the rest of the securing device 1 1 thinner, ie formed with a lesser height. In this sensor section 19 are a total of three distance-dependent switching devices 21 in the form of a respective reed Contacts are arranged, which are not visible from the outside (see Figures 3 to 6, in which the reed contacts are still shown, as if the housing of the securing device 1 1 would be transparent). The distance-dependent switching devices 21 are connected to an electronics, which is arranged in the interior of the securing device 1 1, in particular in the central portion 17. The electronics are designed to transmit respective status signals by radio depending on the respective switching states of the switching devices 21 or of changes in these switching states. For such a radio transmission, the safety device 1 1 may be designed in particular according to ISO / IEC 14543-3-10, so that the emission of respective state signals can basically be done battery-free. In the embodiment shown, however, the securing device has a battery compartment 23 for receiving batteries as a voltage source for the safety device 11 at the end of its longitudinal extension opposite the sensor section 19.

The securing device 1 1 is formed so thin that it (as shown in Fig. 2) in the fold between the frame 13 and an associated wing (not shown) can be attached to the frame 13. In this respect, the securing device 1 1 shown in FIG. 1 is a frame part. The arrangement shown in Fig. 2 is purely exemplary. In principle, the securing device 1 1 can be arranged on different frame 13 with different cross sections, which may provide spacers between individual holes 15 and the frame if necessary, if the frame 13 does not provide a sufficiently wide area for the arrangement of the securing device 1 1.

The securing device 11 is preferably arranged on the respective frame 13 in such a way that the securing device 11 and one on the respective one Wing provided fitting assembly 25, in particular an espagnolette, each other with the wing closed straight, so in particular are arranged parallel to each other substantially adjacent to each other. The distance between the securing device 11 and the fitting arrangement 25 is then preferably such that a permanent magnet 27 provided on the fitting arrangement 25, that is to say on the wing, can interact with the distance-dependent switching devices 21. In this respect, the permanent magnet 27 represents a wing part of the securing device 11. This interaction is illustrated with reference to FIGS. 3 to 6, in each of which the securing device 11 and a part of a fitting arrangement 25 are shown. In order to show the mutually facing sides of the securing device 1 1 and the fitting assembly 25 in the figures, they are opposite to their actual arrangement one above the other and in the same direction (from the drawing plane out) shown pointing. The actual arrangement of the securing device 1 1 and the fitting assembly 25 to each other is obtained at least substantially, if the respective figure would be folded on a horizontally extending between the securing device 1 1 and the fitting assembly 25 line.

In this case, Figs. 3 and 5 differ from Figs. 4 and 6 with respect to a respective offset between the securing device 1 1 and the fitting assembly 25 transversely to the respective longitudinal extent, which in the figures a different distance between the securing device 1 1 and Be - impact assembly 25 corresponds. The figures are to be understood such that in Figs. 3 and 5, the securing device 1 1 and the fitting assembly 25 are at least substantially flush or congruent to each other, so there is no offset transverse to the respective longitudinal extent. In contrast, FIGS. 4 and 6 show such an offset, which can occur, in particular, when the wing is not completely flush with the frame 13. directed, that is not completely closed. The offset is not necessarily parallel (as shown), but the securing device 1 1 and the fitting assembly 25 may also be angled offset to each other in particular at a rotational opening of the wing. As the closed state of the wing, at least in the embodiment shown, only the state in which the wing is at least substantially completely closed, as in FIGS. 3 and 5, is considered. An offset, as shown in Figs. 4 and 6, however, corresponds to the open state of the wing. Furthermore, FIGS. 3 to 6 differ with regard to the respective position of a pin 29, which is similar to an ordinary locking pin, and which has the permanent magnet 27. In this case, the pin 29 may for this purpose in principle at least partially, in particular in a head region, also be formed even permanent magnetic. The pin 29 is at a

Driving rod 31 of the fitting assembly 25 attached so that it moves along movements of the drive rod 31. The drive rod 31 is largely covered by a faceplate 33 of the fitting assembly 25, which has a slot 35 through which the pin 29 extends so that the pin 29 can move in the longitudinal direction in the slot 35 when the fitting assembly is adjusted.

The fitting arrangement 25 shown has three defined positions, each of which corresponds to a position of the pin 29 in the slot 35. In Figs. 3 and 4, the fitting assembly 25 assumes a rotational opening position which is an unlocking position in that the sash is fully rotatable when the fitting assembly 25 is in the rotational opening position. The pin 29 is located within the slot 35 in the middle position shown in Figs. 3 and 4. In FIGS. 5 and 6, the fitting arrangement 25 assumes a closed position, which is a locking position of the fitting arrangement 25, since the wing is in this position of the fitting arrangement 25 in itself is usually blocked by the fitting assembly 25 against opening. The pin 29 is located within the slot 35 in the right position shown in Figs. 5 and 6. In the third, not shown in the figures position of the fitting assembly 25, the pin 29 is located within the slot 35 on the left. This position of the fitting arrangement 25 is a tilting opening position in which the wing can be tilted to a limited extent to a defined gap. However, since in this position, a full opening of the wing is prevented, this position is defined as a further locking position of the fitting assembly 25. In principle, however, the tilt opening position could also be considered as an unlocking position.

Further, in Figs. 3 to 6 respectively below the three distance-dependent switching devices 21 of the securing device 1 1, the respective switching state of the individual switching devices 21 indicated by a respective symbol, wherein a cross (x) the open switching state and a circle (o) the closed Switching state of the respective switching device 21 represents.

As can thus be seen from the figures, in the closed state of the wing (FIGS. 3 and 5), depending on the respective position of the fitting arrangement 25, a respective other distance-dependent switching device 21 is closed. Because depending on the position of the fitting assembly 25, the permanent magnet 27 is located on the pin 29 in the vicinity of a respective other switching device 21st (In intermediate positions of the fitting arrangement 25, two switching devices 21 can also be closed in each case if their ranges overlap, or none if the ranges are disjoint.) In this way, the safety device 1 1 can detect the switching states of the distance-dependent switching devices 21 Which of the positions of the fitting assembly 25 is present. In contrast to the closed state, in the open state of the wing, all distance-dependent switching devices 21 have the open switching state, since the permanent magnet 27 on the pin 29 is then out of the range of all the distance-dependent switching devices 21 provided on the securing device 11. Therefore, since none of the switching devices 21 is closed, the open state of the wing can be detected. (From an intermediate position of the fitting assembly 25, in which also none of the switching devices 21 may be connected, the open state can be distinguished if necessary, characterized in that in the open state all Schaltvorrich- tions 21 longer than a certain minimum duration are open because the intermediate positions of the fitting assembly 25 in The rule, the fuse device 1 1, the detected switching states of the respective distance-dependent switching devices 21 at least substantially unchanged, so for example only combined with each other and / or in any Encoded way, output as a respective state signal. Such a status signal can then be received by an external device, for example an alarm device, and evaluated for the presence of a regular or an irregular state. However, such an evaluation can also be made in the security device 1 1 itself. The safety device 1 1 can then output a regular signal or an irregular signal as the respective state signal, by means of which it can be detected in each case without further evaluation whether a regular or an irregular state is present.

A regular state is shown in particular in FIG. 4. In this case, the fitting assembly 25 is in the unlocked position and the wing in the open state. This is permissible because the wing is released in the unlocked position of the fitting assembly 25 for full opening. FIG. 6 on the other hand shows an example of an irregular state. Because it is the open state of the wing, although the fitting assembly 25 assumes a locked state in which the wing should not be open. This can be interpreted as an indication of an inadmissible opening, eg prying open the sash. (Even in the tilt opening position of the fitting assembly 25, not shown, a detected open state may be considered irregular, namely, when the securing device is mounted on the side of the tilting axis on the frame 13, where the wing should not move away from the frame 13 when tilting.)

However, the switching states in the state shown in FIG. 4 are not different from those in the state shown in FIG. 6. In order to distinguish between a regular and an irregular state by means of the switching states, it is therefore necessary to take into account the position of the fitting arrangement 25 which was present at the moment when a transition from the closed state to the open state of the wing was detected. If, for example, a change in the switching states from the switching states of the switching devices 21 shown in FIG. 3 to the switching states shown in FIG. 4 is detected, it can be deduced that the wing has gone into the open state when the fitting arrangement 25 Unlocked position took what is allowed. In contrast, a change in the switching states from the switching states of the switching devices 21 shown in FIG. 5 to the switching states shown in FIG. 6 represents a transition which is inadmissible, since in the latching position of the fitting arrangement 25 assumed in FIG should be locked in the open position of the wing shown in FIG. 6.

A security device 11 according to the invention, as shown by way of example in the figures, can be easily arranged both on existing windows, doors or the like and also be integrated into existing alarm systems. and allows reliable detection of respective regular or irregular conditions. Compared to a sensor that detects only the respective position of the fitting assembly 25, the safety device 1 1 also has the advantage of improved comfort, since automatically based on the additional detection of the respective state of the wing between an allowable opening and an inadmissible opening of the wing can be distinguished.
