Description

The invention relates to a device for detecting the position of an actuating handle and / or a window sash, a door leaf or the like.

Actuation handles are known in many embodiments. They serve, for example, for opening and closing a window or a door, in particular a window sash or a door leaf, wherein a handle is usually formed by a square pin for rotational entrainment of an associated actuator in the sash or door leaf, such as a locknut or a window gear. For mounting on the window or door wing usually a stopper body is provided, with which the handle is axially fixed-rotatably connected. Locking or spring means formed within the stop body define preferred or standard angular positions of the handle, each angular position being associated with a particular operative position of the window or door (e.g., closed, open-hinged or open-tilted in windows).

If buildings such as residential buildings or office buildings, whose windows and doors are usually provided with operating handles, equipped with alarm systems, it is necessary to close before activating all windows and doors. But even without an alarm system, it is usually desirable that a building is completely closed in the absence. In order to be able to detect or monitor this from only one central location, sensors are installed in the area of all the window and door wings of the building, usually in the form of electrical, magnetic and / or optical contacts are formed. Each sensor detects the position of an associated door or window sash or a fitting and passes a change of state via a connecting line to an evaluation device. This supplies the sensor element via the connecting line at the same time with the required operating voltage. Each evaluation device is connected via a connecting line with a central reporting device.

A major disadvantage of such systems is that the installation cost is very high because separate cables must be routed to each window and door. All cables must also be assigned to the relevant window or door in one or more control centers, which often leads to wiring problems. Retrofitting of existing buildings is therefore hardly possible or associated with significant investment costs.

In order to reduce the circuit complexity, it has developed sensors with battery or battery operation (see, eg DE-U1-297 18 264 ). The sensors designed as reed switches monitor the closed position of a window sash and the functional positions of the latch mechanism and thus of the window handle, wherein the determined state changes are transmitted wirelessly via a radio link to an evaluation unit.

The problem here is that all batteries must be regularly checked and replaced. This not only results in high maintenance and operating costs. Due to the large number of large windows and doors, a large number of windows and doors generate a high level of environmental pollution with correspondingly high disposal costs.

DE-C2-100 59 582 Therefore proposes a monitoring device for the opening, closing, locking and / or unlocking a window, a door or the like. before, with a base station and an evaluation device attached to the casement. The latter comprises a sensor (reed contact), which detects the locking or unlocking state of a locking pin from the displacement position of a displacing when locking detector, wherein the base frame of the window or the door arranged base station together with the evaluation device forms a transponder unit through which the Ver - Is unlocked or unlocked state without contact. At the same time there is the existence or absence of one Connection between the evaluation device and the base station information about the opening and closing state of the window or the door leaf.

This means that the evaluation device mounted on or in the window sash does not require a power supply. However, the circuit complexity is still relatively high, because the base station via an electrical line with a Weiterverarbeitungseinrichlung, e.g. an alarm system is to connect. Base station and evaluation must also always be arranged opposite each other within the frame elements in order to ensure reliable operation of the monitoring device can. The installation in the rebate air area can often lead to sealing problems. A subsequent installation is only conditionally possible and associated with high costs.

An in DE-C2-101 50 128 disclosed sensor system dispenses with both batteries and on connecting lines. Each sensor is assigned to this a voltage generator, which gains energy from the environment or from a mechanical movement and converts it into electrical energy, which is stored for the operation of the sensor and a radio transmitter. The voltage generator may be a solar cell, a piezoelectric transducer or an inductive converter, wherein the energy store is a capacitor that provides the necessary for the most short-term operation power even when the voltage generator can not provide energy. When the voltage in the capacitor reaches a sufficient level, a timer circuit is activated which activates the entire system. Each connected sensor is polled at definable time intervals. The detected change of state or a measured value is coded together with an identification number in a radio transmission message and sent by the radio transmitter via a radio link to a central evaluation unit. This transmits the information to power grid-connected actuators, a bus system or suitable display elements.

Even such a sensor system can be installed only conditionally retrofitted, because in the area of already installed window and door leaves usually only little space is available and the individual sensors (preferably reed contacts with associated permanent magnets as a signal transmitter) optically disturbing most. In addition, each sensor must be placed so that the movement of the window or door leaf is always detected reliably, which is not always easy, for example, in narrow window niches or double-wing doors. If there is insufficient energy available, the monitoring can not be performed or not at the required time, because the timer circuit activates the sensor system only when the energy storage is fully charged.

In DE-103 15 765 A1 An electromagnetic energy converter is presented, which also provides a minimum electrical energy from small movements. However, an operation of a switching element via an actuating element does not have this energy converter.

In WO 2004/109236 A1 describes a system for wireless determination of the position of a mechanical power transmission device, in particular a window handle, with a storage device for storing electrical energy, a sensor element which detects the position of the window handle and is equipped with sensor electronics. The latter monitors the sensor element and controls a radio transmitter which sends a signal to a receiver at regular intervals. A photovoltaic power supply device supplies the storage device with electrical energy. For storing the photovoltaic energy, however, an accumulator or capacitor is necessary here. Also, in this device, magnetic-sensitive sensors are used to detect the position of the window handle.

The aim of the invention is to avoid these and other disadvantages of the prior art and a device for detecting the position of an actuating handle and / or a window, a door or the like. To develop, which is constructed inexpensively by simple means and allows always reliable and needs-based wire and battery-free monitoring of windows and doors. It should also be easy to handle and easy to retrofit in a visually appealing manner, especially in combination with existing window and / or door fittings.

Main features of the invention are specified in the characterizing part of claim 1. Embodiments are the subject of claims 2 to 25 and the independent claim 26th

A device according to the invention for detecting the position of an actuating handle and / or a window sash, a door leaf or the like. has at least one radio switch which generates and sends an identifiable radio signal after actuation of a switching element and generates the necessary energy itself. At least one actuating element couples the actuating and / or rotary movement of the actuating handle and / or the pivoting movement of the window sash, the door leaf or the like. with the switching element of the radio switch such that upon reaching each functional position of the handle and / or a position of the sash, the door leaf or the like. the switching element is actuated. In this case, the actuating element converts the actuating and / or rotary movement of the handle into an actuating and / or pivoting movement for the switching element. The actuating element is a control disk, a control roller or the like. Axially rotatably mounted in a housing and rotatably engageable with the actuating handle is engageable. Between the actuating element and each switching element at least one force transmission element is provided.

This makes it possible to detect the various functional positions of the actuating handle without having to make installations in the window or in the door. It does not even require a separate power supply. Also, no separate supply or data cables need to be laid. As soon as the handle and / or the window sash reach an excellent functional position, the switching element is actuated. The radio switch generates a radio signal and transmits it, for example to a central receiving station, which can evaluate and process the radio signal.

It is particularly advantageous that the radio signal is triggered only when reaching a functional position of the handle. It is therefore for capturing the position of a Window or door handle irrelevant, at which angle this is. The assignment of the radio signals takes place directly on the functional positions of the actuating handle, ie only when they are actually achieved, the transmission of a radio signal.

Moreover, one can determine with the device according to the invention an unauthorized opening of the window or door (burglary situation), because as soon as the sash profile moves away from the frame profile, although the window handle vertically downwards, that is closed, the radio switch generates a radio signal. It also sends this information to the central receiving station so that the recipient can recognize that a window closed with the actuating handle is opened without operating the handle, i. has been broken.

Because the radio switch generates the necessary electrical energy itself, the device is overall energy self-sufficient. The laying of connecting cables or the use of batteries is therefore not necessary. In addition, the desired information is transmitted over a radio link, i. Data lines are also not necessary. Both the training and retrofitting of the device according to the invention is therefore extremely simple, not least because the connection of the device takes place directly to the rotational movement of the actuating handle.

In the Fig. 1 generally designated 10 device is used for detecting and monitoring the position of an actuating handle 20 and the wireless transmission of the detected position information to a (not shown) central evaluation unit, such as an alarm system, a bus system or the like.

The actuating handle 20 has a handle 21 with a handle main part 22 and a handle neck 23, which is axially fixed-rotatably mounted on a stop body 24, for example, a rosette. This is fastened by means (not shown) fixing screws together with the device 10 on a (not shown here) window sash F, wherein a rotationally fixed in the handle neck 23 driver 28, preferably a square pin, through the device 10 into a (also not visible) Actuator engages in the sash F. The latter is articulated in a manner known per se to a (not shown here) frame R, which is fixedly mounted in a window opening of a building.

The device 10 comprises a housing 12 which, like Fig. 2 shows - is provided on its underside with cam 14. These take the mounting screws and ensure a positional fixation on the window sash F. Concentrically over the cam 14 12 blind holes 15 are introduced in the housing, whose distance and dimensions the cam 25 of the stopper body 24 correspond. The entire assembly 10, 20 can thereby axially and rotationally fixed to the sash F mount.

In the housing 12 of the device 10 is seated a radio switch 30, which generates and sends after actuation of a switching element 34 by means of an electronic circuit 36 a receivable by the evaluation and identifiable radio signal. The electronic circuit 36 has a processor controller 37 with a microprocessor 35 as well as an electronic memory 38 which conveniently stores information for identifying the handle 20 to be monitored.

The switching element 34 is movable between two switching positions back and forth, the electronic circuit 36 generates a distinguishable radio signal upon reaching each end position of the switching element 34 and sends to the evaluation unit. The radio signal therefore preferably comprises an identification number of the handle 20 which can be called up from the memory 38 and at least information about the direction in which the switching element 34 has been actuated.

The energy necessary for the operation of the electronic circuit 36 is generated by the radio switch 30 itself. For this purpose, a transducer element 32 is provided, for example a piezoelectric, an electrodynamic, a magnetodynamic and / or a magnetostrictive element, which converts mechanical energy into electrical energy.

The mechanical energy is introduced via the switching element 34 in the transducer element 32, wherein the switching element 34 is preferably designed as a spring element and part of a dead center mechanism. This ensures that the radio switch 30 always has unique switching states. If the switching element 34 is moved, the introduced mechanical energy is initially stored until a certain point is reached. If this is exceeded, the energy stored in the spring element 34 is emitted in the direction of the nearest dead center. This is done - regardless of speed, duration and force of the causally acting mechanical actuation by the switching element 34 - a always uniform energy transfer to the transducer element 32, the energy generated is always constant. In addition or as an alternative, it is possible to use a separate spring mechanism (not illustrated) which can be actuated via the switching element 34 and - as described - is coupled to the transducer element 32.

To actuate the radio switch 30 and the switching element 34, an actuating element 50 is provided between this and the actuating handle 20, which is designed as a coupling element and each setting and / or rotational movement of the handle 21 transmits to the switching element 34 of the radio switch 30, so that at Reaching each functional position of the handle 20 and the handle 21, the switching element 34 and thus the radio switch 30 is actuated in a predetermined direction.

The coupling element 50 is preferably a control disk, a control roller 52 or the like., The axially fixed-rotatably mounted in the housing 12 and rotationally fixed on the square pin 28 with the handle 20 is in operative connection. For receiving the square pin 28 a square recess 53 is centrally provided in the control roller 52, while in the outer circumference a circumferential groove 54 is introduced, which has a wave or sinusoidal contour. The latter causes the switching element 34, which may be immediately engaged therewith, to be periodically reciprocated, i. the actuating or rotary movement of the handle 20 is converted into an actuating or pivoting movement for the switching element 34.

One recognizes in 3 and 4 in that the circumferential groove 54 forms a control groove and is designed in such a way that, after every quarter turn (90 ° rotation) of the control roller 52, the switching element 34 passes from one switching or end position into the other. The switching element 34 thus moves symmetrically to a zero position back and forth, wherein in each end position by the radio switch 30, a radio signal is generated.

The control roller or control disk 52 can be locked in at least one angular position, which suitably correspond to the functional positions of the handle 20. For this purpose, latching means (not shown) may be provided between the housing 12 and the control disk 52. Usually, however, the actuating handle 20 itself has within the stopper body 24 via suitable latching means which define preferred or standard angular positions of the handle 21, each angular position of a particular functional position of the handle 21 is associated.

So that no undesired forces can act on the radio switch 30 or on the switching element 34, a force transmission element 60 is provided between the coupling element 50 and the switching element 34. This is it For example, a rocker 62 which is pivotally mounted in the housing 12 with lateral axle journal 63. It also surrounds the cam 14 of the housing 12 with a recess 68, so that the housing 12 and thus the device 10 have extremely compact dimensions.

At its end 64 facing the coupling element 50 or the control disk 52, the rocker 62 carries a finger 65, a pin or the like which slidably engages in the control groove 54 of the control roller 52 with as little movement play as possible. The opposite, the radio switch 30 facing the end 66 of the rocker 62 is formed as a bracket 67 or as a terminal. This detects the switching element 34 of the radio switch 30th

The bottom of the housing 12 is suitably closed by a housing bottom 13.

The operation of the device 10 is shown schematically in the 3 and 4 recognizable. Once the handle 21 is moved from an excellent detent position to another and this subsequent detent position reached (see Fig. 3 ), so an operation of the radio switch 30, that is, the switching element 34 is moved out of its previous position in a different switching position. Once this is achieved, the transducer element 32 generates electrical energy used by the electronic circuit 36 to generate a radio signal. This signals the evaluation unit that the handle 20 has been actuated, wherein the radio signal is transmitted only when actually another detent position has been reached. If the handle is only moved "back and forth", no signal is generated. The device 10 thus always ensures reliable statements about the position of the handle 20.

If the handle 21 - as in Fig. 4 pivoted to the next operative position, for example, 90 ° from the closed position to the open position, the control roller 52 also rotates through 90 ° and the rocker 62 is by the forced coupling between the finger 65 and the cam 54 around the axle 63 around pivoted. At the same time, the switching element 32 of the radio switch 30 is folded. This generates via the transducer element 32 electrical energy, however, changes the sign due to the change in direction. This information is detected by the electronic controller 36 and integrated into the radio signal. The Evaluation unit detects that the handle 21 has been moved from its previous position, eg closed, in the open position.

In order to distinguish at least one further functional position of the handle 21, a separate sensor 70 is arranged in the housing 12 (see Fig. 5 ). This is preferably an electromagnetically or electrostatically actuated switching contact, for example a reed contact 71, which can be actuated by a permanent magnet 72. The reed contact 71 is seated for this purpose on the longitudinal center of the housing 12 between the outer cam 14 and the control roller 52, the edge of the permanent magnet 72 carries. This is arranged so that the reed contact 71 is always closed when the handle 20 and the handle 21 are in tilted position. The reed contact is connected via electrical lines 75 to the electronic circuit 36 of the radio switch 30.

Now stands the handle 21 - as in Fig. 3 shown - in the closed position, ie to "6 o'clock", so the square pin 28 has brought the shift drum 52 in an angular position in which the rocker 62 is tilted with the clamp 67 down. Upon reaching this position was generated via the switching element 34 in the radio switch 30, for example, a voltage pulse with a positive sign.

If you now turn the handle 21 in the open position of the window, ie to "3 or 9 clock", rocker 62 pivots the terminal 67 upwards (see Fig. 4 ). The coupled switching element 34 of the radio switch 30 reaches its other end position, wherein the voltage pulse generated thereby now has a negative sign.

This polarity change is taken into account in the radio telegram of the electronic circuit 36. The receiver therefore recognizes whether the handle 21 is in the "open" or "closed" rotational position.

If the handle 21 is rotated by a further 90 ° to "12 o'clock", the shift drum 52 pivots the rocker 62 back to its original state, ie the clamp 67 and the associated switching element 34 are moved downwards. The radio switch 30 again generates a voltage pulse with a positive sign. At the same time, however, the reed contact 71 is closed by the magnet 72. The electronic circuit 36 thus receives an additional signal, from which the processor controller 37 recognizes that the handle 21 is not in the closed, but in the tilted position. The radio signal is modified accordingly, so that the evaluation unit can utilize this switching state or this position of the handle 20 accordingly.

In another embodiment (not shown) of the device 10, the sensor 70 is not at the "12 o'clock position" but is offset by 180 degrees at the so-called "6 o'clock position", i. the reed contact 71 provides an additional switching signal whenever the handle 21 and the handle 20 are in the "closed" position. If the reed contact 71 fails once, the radio switch reports an unsecured state (window tilted), which can be easily checked.

Another important embodiment of the device 10 is in Fig. 6 shown. Here, the housing 12 and the stopper body 24 are structurally combined. This gives an extremely compact design, which differs only slightly from conventional fittings.

This in Fig. 7 shown embodiment of a device 10 according to the invention serves not only for detecting and monitoring the position of an actuating handle 20, but for simultaneous monitoring of the position of the sash F with respect to the window frame R.

The (not shown here) window handle 20 is - as in the embodiments of Fig. 1 to 6 - Via the driver 28, which rotates in a bearing 55 rotatable first actuator 50 and the pivotally mounted power transmission element 60, 62 to the first switching element 34 of a first radio switch 30 which transmits the captured position information wirelessly to a (not shown) central evaluation unit, for example an alarm system, a bus system or the like.

For monitoring the position of the window sash F relative to the frame R, a further radio switch 130 is provided in the housing 12 of the device 10, which is preferably arranged in the longitudinal direction of the housing 12 in alignment behind the first radio switch 30. He has his own further switching element 134, which - like Fig. 8 and 9 show - can be actuated by another actuator 150 via another power transmission element 160.

The further actuating element 150 is, for example, a bolt 151 fastened to the window frame R, which, when the window is closed, projects through a through bore 18 introduced into the window sash F and ends with a probe tip 152 formed in the free end of the housing bottom 13 and / or in the housing 12. The housing bottom 13 is for this purpose provided with a corresponding bore 16 or recess whose diameter is greater than the outer diameter of the probe tip 152 and which is smaller than the outer diameter of the bolt 151. This may be rigidly connected to the frame. To compensate for dimensional tolerances, however, the pin 151 is preferably mounted longitudinally displaceably in a sleeve 155 against the pressure of a spring 154. The latter is rigidly anchored in frame R.

The power transmission element 160 is a substantially cylindrical pressure piece 161, which is mounted longitudinally displaceably in a guide 162 and is permanently loaded by a spring 164 in the direction of the frame R (see Fig. 10 ). It is in engagement with the switching element 134 of the radio switch 130 and protrudes in its rest position into the bore 16 of the housing bottom 13. An example formed laterally shoulder 166 serves as a stop which rests on a shoulder 168 of the housing bottom 13 and which is provided for connecting the pressure piece 161 to the switching element 134 with a mouth-shaped recess 167 which engages around the free end of the switching element 134 on both sides.

Closing the window, the actuator 150 is received by the bore 18 of the sash F and the probe tip 152 of the bolt 151 penetrates into the bore 16 of the housing bottom 13 a. In this case, the pressure piece 161 deviates against the spring 164 to the rear, wherein the spring 164 of the pressure piece 161 is weaker than the spring 154 of the bolt 151. Its length or the length of the probe tip 152 are selected such that the pressure piece 161 with the window closed reached a rear end position. The pin 151 can penetrate into the housing 12 only with the probe tip 152 due to the smaller diameter bore 16. He finds rather in the closed position of the window on the bottom 13 of the housing 12 a stop, the spring 154 always provides the necessary tolerance compensation. At the same time it is ensured that the pressure piece 161 always has the same Axialhub. When the window is opened, the pin 151 releases the pressure piece 161. This is brought by the spring 164 in its front stop position.

It can be seen that the opening and closing of the window generates a longitudinal movement of the pressure piece 161 and that this movement on the switching element 134 of the Wireless switch 130 is transmitted, wherein in each end position of the pressure piece 161, the switching element 134 and thus the wireless switch 130 is actuated in a predetermined direction. This generates by means of a (unspecified) electronic circuit in each case a radio signal and sends it to the evaluation unit. Incidentally, the other radio switch 130 is constructed like the first radio switch 30, preferably both components 30, 130 are identical.

The first radio switch 30 of the device works as already described. However, the signal of the second or further radio switch 130 supplements the signal of the first. If this signals a closed window because the window handle 20 is in its corresponding position (usually "6 o'clock") and the second radio switch 130 is activated by opening the window by the pin 151 releasing the pressure piece 161, the evaluation unit recognizes that the window has not been opened via the window handle 20 and thus not regular. An alarm device can immediately report a "break-in".

On the other hand, if the window handle 20 is in an open position, the signal of the second radio switch 130 is simply suppressed because the window has been regularly opened via the window handle 20 and the device 10 only has to recognize in which functional position the handle 20 is located.

While in the embodiment of Fig. 7 to 10 each actuator 50, 150 has a separate radio switch 30, 130, each with its own switching element 34, 134, sees the invention in the embodiment of Fig. 11 to 14 in that the actuating elements 50, 150 and the respectively associated power transmission elements 60, 160 are assigned to a common radio switch 30.

In order to be able to generate a "break-in signal" with only one radio switch 30, the control groove 54 of the control roller 52 is modified in such a way that the rocker switch 62 is pivotable even if the actuating handle 20 is not rotated. For this purpose, for example, the clear height of the cam 54 in the control roller 52 of the actuator 50 - as in particular Fig. 14 shows - formed in a peripheral region higher than the end 65 of the rocker 62 so that it can move up and down within the groove 54. The peripheral area with the higher trained area of the cam groove 54 is always in the area of the rocker 62, when the operating handle 20 is in the "window closed" position ("6 o'clock" position).

The slidably guided within the guide 162 pressure piece 161 of the power transmission element 160 disposed in the recess 68 of the rocker 62, wherein the lateral projection 166 - as well as the radio switch 30 facing the end 66 of the rocker 62 - connected to the free end of the switching element 34 of the radio switch 30 is. Thus, both the rocker 62 and the pressure piece 161 is connected to the switching element 34 of the radio switch 30, which can therefore be activated by both actuators 50, 150.

While Fig. 11 shows the state of the device 10 with the window handle 20 closed and window sash F closed is located in Fig. 13 the window handle 20 remains in the closed position (window closed) while the window has been opened. The window sash F has thus far moved away from the frame R, that the actuating element 150 is disengaged from the power transmission element 160. The pressure piece 161 is brought by the spring 164 in its front end position, wherein the lateral projection 166, the switching element 34 entrains. The radio switch 30 generates the necessary energy and transmits a radio signal.

• ■ Modus A: Fenster geschlossen; Fenstergriff 20 geschlossen; das Ende 66 der Wippe 62 ist nach oben geschwenkt (siehe Fig. 11);
• ■ Modus B: Fenster offen; Fenstergriff 20 offen; Reedkontakt aus, das Ende 66 der Wippe 62 ist nach unten geschwenkt (siehe Fig. 12);
• ■ Modus C: Fenster gekippt; Fenstergriff 20 in Kippstellung; Reedkontakt aus, das Ende 66 der Wippe 62 ist nach oben geschwenkt (nicht dargestellt);
• ■ Modus D: Fenster offen (Einbruch); Fenstergriff 20 geschlossen; Reedkontakt ein, das Ende 66 der Wippe 62 ist nach unten geschwenkt (siehe Fig. 13).

In order to be able to distinguish this radio signal "break-in" from the signal "window closed", one uses the additional sensor 70, which is also preferably designed as a reed contact. With this additional switching contact, the evaluation unit can recognize the following states:

• ■ Mode A: window closed; Window handle 20 closed; the end 66 of the rocker 62 is pivoted upwards (see Fig. 11 );
• ■ Mode B: window open; Window handle 20 open; Reed contact, the end 66 of the rocker 62 is pivoted downward (see Fig. 12 );
• ■ Mode C: window tilted; Window handle 20 in tilted position; Reed contact, the end 66 of the rocker 62 is pivoted upwards (not shown);
• ■ Mode D: window open (burglary); Window handle 20 closed; Reed contact, the end 66 of the rocker 62 is pivoted downward (see Fig. 13 ).

While in the modes A to C, the end 65 of the rocker switch 62 in the (tight) control groove 54 are forced, it is necessary for the burglary mode D, a pivoting of the rocker 62 in mode A. This is in Fig. 14 good to see. The

Control groove 54 is formed here substantially higher than the end 65 of the rocker 62: As a result, the rocker switch 62 in the burglary case according to mode D despite still downwardly facing window handle 20 and thereby trigger a transmit pulse in the radio switch.

In order to ensure an always safe system of the rocker 62 within the cam groove 54 this is loaded by a spring 69. In the relaxed state of the spring 69 ensures that the end 65 of the rocker 62 rests on the lower edge of the cam groove 54. The spring force of the rocker spring 69 is greater than the spring force of the switching element 34 of the radio switch 30, so that the rocker 62 of the "up and down" within the control groove 54 can always follow.

In the event of burglary, the frame-side pressure pin 151 moves away from the transmitter-side pressure piece 161; the compression spring 164 relaxes. Since this in turn is stronger than the rocker spring 62, the rocker 62 can pivot and trigger the radio signal via the leaf spring 34 of the radio switch 30. Pressure piece 161 engages over the rocker bar. In mode C (tilted) raises the (here close) cam 54 via the rocker 62 the pressure piece 161 a form-fitting to the radio switch 30 again provides a voltage pulse.

The invention is not limited to one of the above-described embodiments, but can be modified in many ways. Thus, the device 10 can be used in numerous other embodiments, for example, for monitoring the closed state of a door bolt or a door leaf. Since the bolt is usually only in two positions, the device 10 can be used without additional sensor 70. However, the latter can also record further closed positions here. Also, additional sensors can be used in doors and windows to detect further opening or pivoting position. The corresponding information from the sensors can be forwarded to the electronic circuit 36 and sent as needed via the radio signal.

As sensors 70, instead of the reed switches, it is also possible to use optoelectronic components or switch contacts, such as switching mats or micro-switches.

The further radio switch 130 in the embodiment of Fig. 7 to 10 can also be carried out separately and installed as a separate assembly on the window or integrated into the sash F.

It is also possible to use the device 10 on or in skylights, shut-off gratings, or shaft flaps, wherein the further force transmission element 60 - depending on requirements - a lever mechanism, a transmission or the like. can be.

It can be seen that the device 10 for monitoring the position of a window handle has a generally elongate housing 12 with two cam depressions 15 for a standard window handle rosette 24 which can be screwed onto it. The axial continuation of the depressions 15 or the screw holes formed therein opens into two cams 14, which engage with the window sash. Window handle 20 and switch housing 10 are thus struck together, the device 10 is sandwiched between the handle 20 and the window.

• ■ Der Schaltwalze 52, deren tangential umlaufende, nutartige Schaltkurve 54 den Finger 65 der Wippe 62 führt.

The interior of the housing 12 consists essentially of three components.

• ■ the radio switch 30 with radio transmitter, antenna and energy generator;
• ■ Approximately in the middle of the right screw screw 14 interspersed rocker switch 62 with a front finger 65 and a rear bracket 67;
• ■ The shift drum 52, the tangential circumferential, groove-like switching cam 54 guides the finger 65 of the rocker 62.

The shift drum 52 is axially fixed-rotatably mounted in the housing 12. It is penetrated in the broken state axially by the square pin 28 of the window handle 21 and thus able to transmit desired torques.

By rotation of the handle 21 and thus the shift drum 52, the switching rocker 62 is pivoted about the finger 65 about the axle 63, which causes an approximately comparable movement on the opposite side 66 of the rocker 62. This movement serves to drive the switching element 34, preferably a leaf spring element which has only two stable end positions. Therefore, the switching element 34 snaps abruptly when turning the window handle 21 from one position to the other, which is used in the radio switch 30 to induce a voltage pulse. This in turn supplies the electronic circuit 36 with energy, which sends a corresponding radio signal with information about the position of the handle 20 and the handle 21.
