Description

The The invention relates to a device for detecting the position of a Actuating handle.

Actuating handles are known in many forms. They serve for example for opening and Shut down a window, a door or the like being a handle mostly over a square pin for rotational entrainment of an associated actuator formed in the window or door is, about a castle nut or one Window transmission. For the mounting on the window or door leaf is usually a stopper body present, with which the handle is axially fixed-rotatably connected. Within the stopper body trained latching or spring means define preferred or standard angular positions the handle, each angular position usually a certain functional position of the Window or the door is assigned (for example, windows closed, open-pivotable in windows or open-tilted).

Become building such as. building site or office building whose Windows and doors usually with Actuating handles equipped with alarm systems, it is necessary to before activating all Windows and doors close. But even without alarm system, it is usually desirable that a building at Absence completely closed is. To notice this from a single central point or monitor to be able to be in the range of all Window and door of the building Sensors attached, usually in the form of electrical, magnetic and / or optical contacts are formed. Each sensor detects the position an assigned door or window sash or a fitting and gives a state change via a connection line to an evaluation device on. This supplies the sensor element via the Connecting line at the same time with the required operating voltage. Each evaluation device is over a connecting line connected to a central signaling device.

One major disadvantage of such systems is that the installation cost is very high, because each window and each door separate Cable must be laid. All Cables are also in one or more control centers of the relevant Window or door assign, which is not uncommon to circuit problems leads. A retrofit already existing buildings is therefore hardly possible or associated with significant investment costs.

Around to reduce the circuit complexity, you have sensors developed with battery or battery operation (see for example DE-U1-297 18,264). Monitor the sensors designed as reed switches the closure position a window sash as well the functional positions of the latch mechanism and thus of the window handle, wherein the determined state changes wirelessly over a radio link are sent to an evaluation unit.

Problematic Here is that all Batteries regularly checked and replaced Need to become. This not only results in high maintenance and operating costs. By in big buildings not infrequently big Number of windows and doors creates a high environmental impact with correspondingly high disposal costs.

DE-C2-100 59 582 beats therefore a monitoring device for the opening, closing, locking and / or unlocking state of a window, a door or the like. before, with a base station and an evaluation device attached to the casement. The latter includes a sensor (reed contact), from the displacement position of a when the declaring relocator relocates the locking mechanism or unlocked state of a lock pin detected, wherein the base station arranged on the frame of the window or the door forms a transponder unit with the evaluation device, via the the locking or unlocking is transmitted without contact. simultaneously indicates the existence or absence of a connection between the evaluation device and the base station information about the opening and closed state of the window or door leaf.

In order to comes mounted on or in the casement Although evaluation device without power off. The circuit-technical However, effort is still relatively high, because the base station via a electrical line with a further processing device, e.g. an alarm system is to connect. Base station and evaluation must also within the frame elements always opposite each other be arranged to be a reliable Function of the monitoring device guarantee to be able to. The installation in the rebate air area can often lead to sealing problems to lead. An afterthought Installation is also limited and possible with high costs connected.

A sensor system disclosed in DE-C2-101 50 128 dispenses with both batteries and 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, where in the energy storage 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 thereby detected change of state or a determined measured value is coded together with an identification number in a radio transmission telegram 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.

Also such a sensor system can be only conditionally afterwards install, because in the range of already built-in windows and Door leaves mostly only little space available stands and the individual sensors (preferably reed contacts with associated Permanent magnets as a detector) optically disturbing. In addition, everyone must Sensor be placed so that the Movement of the window or door leaf always reliable detected becomes what e.g. not in narrow window niches or double-winged doors always easy. If there is insufficient energy available, can The supervision not or not performed at the required time, because the timer circuit activates the sensor system only when the Energy storage completely loaded.

aim The invention is to overcome these and other disadvantages of the prior Avoid technique and a device for detecting the position an actuating handle to develop, which is constructed inexpensively by simple means and a always reliable as well as needs-based wireless and batteryless monitoring of windows and Doors possible. It should also be easy to handle and visually appealing Easy to retrofit especially in combination with already existing windows and / or door fittings.

main features The invention are specified in the characterizing part of claim 1. Embodiments are the subject of claims 2 to 29.

A inventive device for detecting the position of an actuating handle has a radio switch, the after actuation a switching element generates an identifiable radio signal and send and for that necessary energy is generated. A coupling element is with the actuating and / or rotational movement of the actuating handle and the switching element the radio switch coupled or coupled so that upon reaching each functional position of the handle, the switching element is actuated.

Thereby Is it possible, to detect the various functional positions of the actuating handle, without being in the Window or in the door Installations must be made. It is not even one separate power supply required. Also, no separate supply or data lines are laid. Once the handle has an excellent Function reached, the switching element is actuated. Of the Radio switch generates a radio signal and sends it off, for example to a central receiving station, which evaluate the radio signal and can process further.

From particular advantage is that the Radio signal only when reaching a functional position of the handle triggered becomes. It is therefore for the detection of the position of a window or door handle irrelevant, in which Angle is this. The assignment of the radio signals takes place immediately above the Functional positions of the actuating handle, i. only when this actually are reached, the transmission of a radio signal.

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. moreover become the desired information about transmits a radio link, i. Data lines are also not necessary. Both the training as well as the retrofitting the device according to the invention is therefore extremely easy, not least because the connection of the device takes place directly on the rotational movement of the actuating handle.

Further Features, details and advantages of the invention will become apparent the wording of the claims as well as from the following description of exemplary embodiments with reference to FIG Drawings. Show it:

2 an oblique view of the device of 1 without actuating handle, partly in section,

3 a sectional view of the device of 1 in a first operating position,

4 a sectional view of the device of 1 in a second operating position,

6 Yet another embodiment of a device for detecting the position of an actuating handle.

In the 1 generally with 10 designated device is used to detect and monitor the position of an actuating handle 20 and for 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 body 22 and a handle neck 23 axially rotatable on a stop body 24 , For example, a rosette is stored. This is by means (not shown) fixing screws together with the device 10 attached to a (also not shown) casement, with a rotatably in the handle neck 23 fixed driver 28 , preferably a square pin, through the device 10 through in a (also not visible) actuating device engages the window sash.

The device 10 includes a housing 12 , the how 2 shows - on its underside with cams 14 is provided. These take the mounting screws and ensure a position fixation on the window sash. Concentric over the cam 14 are in the case 12 blind holes 15 introduced, the distance and dimensions of the cam 25 the stopper body 24 correspond. The whole arrangement 10 . 20 can be axially and rotationally mounted on the window sash.

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

The switching element 34 is movable between two switch positions back and forth, wherein the electronic circuit 36 in each end position of the switching element 34 generates a distinguishable radio signal and sends it to the evaluation unit. The radio signal therefore preferably includes one from the memory 38 Callable identification number of the handle 20 and at least one piece of information about which direction the switching element is in 34 has been actuated.

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

The mechanical energy is transmitted via the switching element 34 and a dead center mechanism (not shown) in the transducer element 32 brought in. The dead center mechanism also ensures that the radio switch 30 always has unique switching states. Will the switching element 34 moved, so the dead center mechanism initially stores the introduced mechanical energy until a certain point is reached. If this is exceeded, the energy stored in the spring elements is released 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 - An always uniform energy transfer to the transducer element 32 whose generated energy is always constant.

Between the actuating handle 20 and the radio switch 30 is a coupling element 50 provided that any adjustment and / or rotational movement of the handle 21 on the switching element 34 of the radio switch 30 transmits, so that upon reaching each functional position of the handle 20 or the handle 21 the switching element 34 and thus the radio switch 30 is pressed.

The coupling element 50 is preferably a control disk, a control roller 52 o.dgl., The axialfest-rotatable in the housing 12 is stored and over the square pin 28 rotatably with the handle 20 is in active connection. For holding the square pin 28 is in the control roller 52 Centric a square recess 53 provided while in the outer periphery a circumferential groove 54 is introduced, which has a wave or sinusoidal contour. The latter causes the optionally immediately engaging therein switching element 34 is periodically moved back and forth, ie the actuating or rotary movement of the handle 20 is in an actuating or pivoting movement for the switching element 34 implemented.

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

The control roller or control disc 52 can be latched in at least one angular position, which expedient the functional positions of the handle 20 correspond. This can be done between the housing 12 and the control disc 52 Be provided locking means (not shown). Usually, however, has the actuating handle 20 even within the stopper body 24 via suitable locking means, the preferred or standard angular positions of the handle 21 define, with each angular position of a particular functional position of the handle 21 assigned.

So no unwanted forces on the radio switch 30 or on the switching element 34 can attack is between the coupling element 50 and the switching element 34 another power transmission element 60 intended. This is, for example, a seesaw 62 , with side journals 63 in the case 12 is pivotally mounted. The pivot axis of the rocker 62 lies perpendicular to the axis of rotation of the control disk 52 , It also encloses the cam 14 of the housing 12 with a recess 68 so that the case 12 and with it the device 10 have extremely compact dimensions.

At her the coupling element 50 or the control disk 52 facing the end 64 carries the seesaw 62 a finger 65 , a pin or the like, in the control groove 54 the control roller 52 intervenes. The opposite, the radio switch 30 facing the end 66 the seesaw 62 is as a staple 67 or formed as a terminal. This detects the switching element 34 of the radio switch 30 ,

The bottom of the case 12 is expedient of a housing bottom 13 locked.

The operation of the device 10 is schematic in the 3 and 4 recognizable. Once the handle 21 is moved from one excellent detent position to another and this subsequent detent position reached (see 3 ), the radio switch is actuated 30 ie the switching element 34 is moved from its previous position into a different switching position. Once this is achieved, the transducer element generates 32 electrical energy coming from the electronic circuit 36 is used to generate a radio signal. This signals the evaluation 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 10 ensures always reliable statements about the position of the handle 20

Will the handle 21 - as in 4 shown - pivoted to the next operating position, for example, 90 ° from the closed position to the open position, so the control roller rotates 52 also at 90 ° and the rocker 62 is due to the forced coupling between the finger 65 and the control groove 54 around the stub axles 63 pivoted around. At the same time, the switching element 32 of the radio switch 30 transferred. This generates over the transducer element 32 electrical energy, however, changes the sign due to the change of direction. This information is provided by the electronic control 36 detected and integrated into the radio signal. The evaluation unit recognizes that the handle 21 has been moved from its previous position, eg closed, in the open position.

At least one more functional position of the handle 21 to be able to distinguish is in the housing 12 a separate sensor 70 arranged (see 5 ). This is preferably an electromagnetically or electrostatically actuated switching contact, for example a reed contact 71 that of a permanent magnet 72 is operable. The reed contact 71 sits 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 wearing. This is arranged so that the reed contact 71 always closed when the handle 20 or the handle 21 in tilt position. The reed contact is via electrical lines 75 to the electronic circuit 36 of the radio switch 30 connected.

Is now the handle 21 - as in 3 shown - in closed initial position, ie to "6 o'clock", so has the square pin 28 the shift drum 52 placed in an angular position in which the rocker 62 with the clamp 67 tilted down. Upon reaching this position was on the switching element 34 in the radio switch 30 For example, generates a voltage pulse with a positive sign.

Now turn the handle 21 in the opening position of the window, ie on "3 or 9 o'clock", the rocker swings 62 the clamp 67 upwards (see 4 ). The switching element coupled thereto 34 of the radio switch 30 reaches its other end position, the voltage pulse generated thereby now having a negative sign.

This polarity change is in the radio telegram of the electronic circuit 36 considered. The receiver therefore detects if the handle 21 on rotational position "open" or "closed" stands.

Will the handle 21 turned by another 90 ° to "12 o'clock", pivots the shift drum 52 the seesaw 62 back to its original state, ie the terminal 67 and the associated switching element 34 are moved down. The radio switch 30 again generates a voltage pulse with a positive sign. At the same time, however, the reed contact 71 from the magnet 72 closed. The electronic circuit 36 receives with it an additional signal, from which the processor control 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 this switching state or this position of the handle 20 can utilize accordingly.

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

Another important embodiment of the device 10 is in 6 shown. Here is the case 12 directly a stop body 24 for the actuating handle 20 , This gives an extremely compact design, which differs only slightly from conventional fittings.

The invention is not limited to one of the above-described embodiments, but can be modified in many ways. So can the device 10 find application in numerous other embodiments, for example, to monitor the closed state of a door bolt. Since this is usually only in two positions, the device 10 also without additional sensor 70 be used. However, the latter can also record further closed positions here. Also, in doors and windows, other sensors can be used to detect, for example, the opening or pivoting position. The corresponding information of the sensors can be connected to the electronic circuit 36 forward and if necessary send via the radio signal.

As sensors 70 Optoelectronic components or switching contacts such as safety mats or micro-switches can be used instead of the reed switch.

You can use the device 10 also on or in operating handles 20 use for roof windows, barriers, or manhole covers, wherein the further power transmission element 60 - As needed - a lever mechanism, a transmission or the like. can be.

It can be seen that the device 10 an overall elongated housing 12 has two cam dips 15 for a screw-on standard window handle rosette 24 , The axial continuation of the subsidence 15 or the screw holes formed therein opens into two cams 14 , which engage with the sash. window handle 20 and switch housing 10 are therefore posted together, the device 10 sandwiched between the handle 20 and the window sits.

The shift drum 52 is axially fixed-rotatable in the housing 12 stored. It is in the worn state axially from the square pin 28 the window handle 21 interspersed and able to transmit desired torques.

By rotation of the handle 21 and thus the shift drum 52 becomes the rocker switch 62 over the finger 65 around the stub axles 63 Panning, what's on the opposite side 66 the seesaw 62 causes a similar movement. 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 snaps 34 when turning the window handle 21 abruptly from one position to the other, something in the radio switch 30 is used to induce a voltage pulse. This in turn supplies the electronic circuit 36 with energy, which is a corresponding radio signal with information about the position of the handle 20 or the handle 21 dispatches.
