    Arrangement for monitoring closure elements
    The invention relates to an arrangement for monitoring closure elements such as doors, windows, lids, flaps, hatches and the like, with a movable actuating means for actuating a closing arrangement and with a sensor arrangement.
    The monitoring of closure elements while maintaining the disclosure and full functionality is a problem that has been addressed in various embodiments in the patent literature.
    In many fields there is a demand for openable element monitoring devices such as doors, windows, hatches and the like. An example of such devices relates to the monitoring of emergency exits in public buildings. These must, as they represent parts of escape routes, be open from the inside. This circumstance is exploited especially in business premises, for example, to remove stolen goods from the building. Furthermore, there is a risk that people gain access to areas of a building that are not intended for them. Since emergency exit doors may not be blocked, they are provided with so-called door guards.
    An apparatus of such a door guard is disclosed in DE 8 914 737 U1. This vertical door guard is located in the range of movement of a door handle. Upon actuation of the door handle, a door slidably disposed on the housing is moved, wherein a switch detects this movement and passes a signal to a signal generator.
    DE 20 2008/011802 U1 shows a device for securing and monitoring actuating rods on emergency exit doors, panic doors or the like, wherein monitoring of the distance between the spacer element and an actuating rod is provided via a sensor device.
    A problem with these devices is that the monitors can be manipulated very easily. If, for example, the door, which is secured exclusively by a trap of the closing arrangement, is violently broken, no t> ♦ * * * * -2-
    Alarm on, since the door handle in one case or the panic bar was not operated in the other case. Another problem with the prior art door guard is that once triggered, it must be returned to the home position manually.
    Another field of application for monitoring devices are, for example, freight containers. Although these must be for authorized persons such. Authorities and cargo personnel, but should be protected against unlawful access. In this case, too, there are several possibilities for monitoring, whereby in most cases the unauthorized manipulation of such monitoring devices is very simple.
    The objects of the present invention are now to provide an arrangement for monitoring closure elements such as doors, windows, lids, flaps, hatches and the like, which are easy to install, simple and reliable in their operation and inexpensive to produce, but to offer increased protection against unauthorized manipulation. Other objects of the invention are that the power can be done over a long period with batteries regardless of a power grid, that the size is largely reduced and, resulting from these advantages, the installation options are flexible.
    The object of the invention is achieved in that at least one position sensor is provided for detecting the movement of the actuating means and / or the closure element and / or the sensor arrangement.
    Furthermore, as advantageous features of the invention should be mentioned that the position sensor is movably arranged limited in a range of movement of the actuating means, wherein the position sensor is movable in at least part of the movement range of the actuating means of this, that limits the position sensor in the range of movement of the actuating means, preferably on the closure element is movably positionable, wherein the position sensor is movable by movement of the actuating means and / or can be brought into operative contact therewith or that at least one position sensor, preferably the sensor arrangement, is provided on or in the actuating means. * ψ -3-
    Furthermore, the invention is characterized by the fact that, accelerations in at least two, preferably in three axes measuring, position sensor is provided that the position sensor is designed as a three-axis digital acceleration sensor, preferably as MEMs acceleration sensor, that the sensor arrangement with a connected to the position sensor
    Data processing unit comprises and that a controlled by the data processing unit signal generator is provided.
    Further advantages result from the fact that upon movement of the actuating means of the position sensor undergoes a rotation, wherein the axis of rotation has a distance from the position sensor, that the actuating means for actuating the closing arrangement is arranged rotatably about an axis of rotation and that a, this rotation detecting position sensor is provided wherein the position sensor has a normal distance to the axis of rotation of the actuating means that an authorization means is provided and that by the sensor arrangement, a movement of the closure element, the actuating means and the position sensor is detectable and or measurable.
    Further advantageous features are that the position sensor and / or the sensor arrangement is provided on a panic bar, that the position sensor and / or the sensor arrangement is provided on a door guard, that the position sensor and / or the sensor arrangement is provided on a door handle, that the sensor arrangement and the signal generator are provided on the actuating means that a power supply is provided, wherein the power supply is preferably designed as a battery or accumulator and that the arrangement according to one of the preceding claims, characterized in that a plurality of position sensors is provided.
    Subsequently, the present invention will be further described with reference to a few selected figures.
    Fig. 1 shows a view of an embodiment as a vertical door guard with a door handle.
    Fig. 2 shows a view of an embodiment as a vertical door guard in combination with a panic bar.
    Fig. 3 shows the view of an embodiment wherein the sensor arrangement is provided directly on or in a panic bar.
    4 shows a longitudinal section through the door guard -4-
    Fig. 1 shows a detailed view of a closure element 1, which is ausgebiidet in this case as a commercial swing door. In this door, a closing arrangement 3 is provided which can be locked or unlocked by actuation of an actuating means 2, which is designed as a door latch in this embodiment. In the range of movement of the doorknob, the sensor arrangement 4 is provided. This is located in a housing 7 which is arranged limited movable on a base plate 6 which is connected to the door. If the door handle is pressed down to open the door, the housing 7 is also moved. According to the section in FIG. 4, the sensor arrangement 4 comprises a position sensor 5 which measures static accelerations and their direction as well as changes in the accelerations and their directions at least in one axis, preferably in two or three axes. Since only the constant gravitational acceleration acts on the sensor in the idle state, and any change in position also causes a change in the acceleration or its direction, an exact position determination can be carried out by the sensor.
    If the sensor assembly is moved from the rest position, this movement is in an electrical Signa! converted and forwarded to a data processing unit 8. This is designed to pass control signals to a signal generator depending on the operating situation.
    In addition, an authorization means 10 is provided. This authorization means is used to operate the locking arrangement without triggering alarm or to turn off an alarm.
    The alarm can be done by signal generator 9, for example, output the acoustic or optical signals and are controlled by the data processing unit 8.
    In practice, there are several operating situations, which are described below:
    The door handle is moved without the authorization means being actuated:
    At low actuation of the actuating means 2 from the normal position to a position of e.g. 5M5 ° tilt triggered a pre-alarm. In this Voralarmsteilung the door is not yet open, since the closure assembly does not release the closure element. By contrast, the sensor arrangement has already been moved so far that the sensor detects this movement. If the user releases the closing arrangement at this time, the door latch would return to the basic position by spring force and the pre-alarm would stop.
    If, on the other hand, the actuating means is moved further downwards, this is detected by the sensor arrangement, in particular by the position sensor, and the signal is forwarded to the data processing unit. The data processing unit checks whether an authorization means is provided. If this is not the case, the main alarm is triggered.
    Operation with inserted authorization means:
    If the authorization means is plugged in, then although the position sensor 5 of the sensor arrangement 4 detects the movement of the actuating means 2. However, since the authorization is given by the authorization means, neither a pre-alarm nor an alarm is triggered.
    Manipulation of the housing:
    If an unauthorized person attempts to manipulate or forcibly remove the housing to prevent triggering of the alarm, then the position sensor also detects the movement of the housing. This movement of the housing in all directions, including rotational movements are detected.
    Manipulation of the closure element and the closure arrangement:
    If, for example, an attempt is made to open the door without actuation of the actuating means, then this change in position is also detected by the position sensor 5, the sensor arrangement 4 and the data processing unit 8. Both strong vibrations, such as the breaking or violent opening of the door, can be measured and a manipulation in which the door is opened without movement of the actuating means can be detected. If, for example, the position sensor detects a rotation of the device around the hinges without an authorization means being plugged in or without the doorknob being pressed, it can be assumed that the opening of the closure element is unlawful and a signal is sent to the signal generator by the data processing unit Posted.
    Fig. 2 shows a similar arrangement with a vertical door guard, wherein the actuating means 2 is designed as a panic bar. The vertical door guard again comprises a base plate 6 which is connected to the closure element 1 and a housing 7 arranged in the movement region of the actuating means 2. When the panic bar is actuated, as in the above case, the housing and the sensor arrangement arranged in it are moved , This movement is detected by the position sensor 5 5 of the sensor arrangement 4. The signal is sent to the data processing unit 8 for further processing.
    3 shows a further embodiment of the arrangement for monitoring closure elements. In this, the sensor assembly 4 is installed directly in a panic bar 10 and therefore arranged directly in or on the actuating means 2. Also in this case, the mechanical movement of the actuating means 2 and manipulation attempts on the arrangement can be detected and to the
    Data processing unit to be passed. An advantage of this embodiment is that the arrangement for monitoring, except for the actuating means 2, is not visible to the user. Also in this embodiment, a pre-alarm can be triggered at a small movement of the actuating means. Upon further movement and unlocking of the closing arrangement 3 or the closure element 1 can from the
    Data processing unit to be passed a control signal to the signal transmitter 20. Furthermore, in turn, vibrations of manipulation attempts can be detected and further processed. A movement of the door leaf without actuation of the actuating means 2 can be detected by the arrangement according to the invention. 25 The sensor assembly 4 comprises the position sensor 5, a power supply 15 which is designed as a battery, a signal generator 9, which may be embodied, for example, as an acoustic or optical signal generator, as well as an authorization means 10. This authorization means is in this embodiment as a non-contact key / Sensor combination executed. This can for example consist of an RFID 30 and a corresponding interrogation device.
    In reality, the operation of the arrangement for monitoring closure elements in this embodiment could proceed as follows: The closure element 1, ie the door, could be, for example, an emergency exit door which unlocks by actuation of the closure arrangement 3 or the actuating means 2 * * • + -7 - can be to allow the opening of the door. Upon movement of the actuating means 2, the entire sensor arrangement, which is arranged in the actuating means 2, moved with. If now the actuating means 2 designed as a panic bar is pressed, a pre-alarm is triggered with a small movement. In this area (for example, between 5 ° and 15 ° tilt to the starting position) sounds an acoustic signal. If the panic bar is released again in this area, it returns to its original position by the spring force of the closing arrangement. The alarm goes off and the system returns to its original position. It should be noted that in the area of the pre-alarm, the closing element can not be opened. This pre-alarm is intended to discourage operators who are unaware that the closure element is alarm-protected.
    If now the panic bar is moved over the area of the pre-alarm and thus the door is unlocked, the main alarm is triggered. This main alarm can also be an acoustic or optical signal of the signal generator 9, but can also be done by connecting the data processing unit 8 with an alarm center, which may also be locally separated. However, if the panic bar is returned to its normal position after the main alarm has been triggered, the alarm remains upright. This can only be turned off by acknowledgment by the authorization means 10, in particular by bringing the RFID to the scanning unit. However, it is also conceivable to carry out this acknowledgment from a central point.
    By using special position sensors, signaling devices and authorization means, it is possible to supply the device autonomously with the internal power supply (battery) over a very long period of time. With standard "AAA" batteries, the battery life can be several years. This has the great advantage that the monitored door no separate power connections must be provided and the device even in Stromausfal! works.
    Furthermore, it is also possible to provide only the sensor in or on the actuating means and to provide the remaining components of the sensor arrangement, such as the data processing unit, in or on the closure element. However, it is advantageous to use the compact dimensions which can be achieved by the use of the sensor arrangement according to the invention, and to use the entire
    Provide sensor arrangement in the actuating means. Subsequently, it is also possible to provide the entire sensor arrangement in the actuating means and also the signal generator and the power supply in the actuating means, e.g. panic bar or doorknob.
    4 shows the view of a vertical section through an embodiment of the arrangement according to the invention as a vertical door guard.
    In this embodiment, the arrangement is realized as a door guard system. In this case, the door, so the closure element 1, fixed to the base plate 6 is connected. The housing 7 is arranged like a rail vertically displaceable on the base plate and has a sensing pin 12 which scans the arranged in the base plate 6 cam 11 during relative movement of the housing 7 to the base plate 6. The housing is further arranged in the range of movement of the Betätigungsmitteis 2, which is shown schematically in this illustration as a cut round door handle 2. When the door latch 2 is actuated to open the door, the housing positioned in the movement area of the actuating means is moved along. The displacement of the housing results in a horizontal movement of the Abtaststiftes 12. At the end facing away from the control cam end of the Abtaststiftes 12, rotatable about the fulcrum lever 14, a lever 13 is provided. On this lever, the position sensor 5 is arranged. Upon movement of the actuating means now experiences the position sensor on the one hand acceleration by the displacement of the housing and on the other hand, an acceleration by the movement of the lever which is driven by the Abtaststift 12.
    For scanning the control cam 11 of the Abtaststift 12 is provided with a roller element 16, for scanning the control cam. The control cam has a cam 17. Upon actuation of the actuating means 2, in particular during movement of the actuating means 2 in the direction of the housing 7, the entire housing is displaced relative to the base plate 6. The pin, biased by the spring 18 rolls with its roller member 16, the control cam 11 of the base plate 6 from. In the upper region of the cam 17, the cam is designed such that, also caused by the spring force is a noticeable resistance to the depression of the housing. This resistance depends on the one hand on the spring force and on the other hand on the slope of the control cam. Thus, in the area of the tip of the cam, a stronger incline can be provided on a short path to achieve the magic feeling of a pressure point. When this point is exceeded, the spring force now acts as an accelerating element, since the rear side of the cam 19 has an inclination and orientation which causes the spring force in an acceleration movement of the housing downwards. In order to prevent the housing from separating from the base plate, a stop 20 is provided in the lower region, which has a surface projecting approximately 90 ° from the base plate over which the roller element 16 of the sensing pin 12 can not roll, since the height of the stop region prevents this , If, as described above, the actuating means 2 moves downwards, all movements of the scanning pin are detected by the position sensor 5 or the sensor arrangement 4. Thus, small angular deviations of the lever 13 as a pre-alarm position can trigger an alarm, which extinguishes again upon return of the actuating means 2, ie releasing the door handle.
    Furthermore, an authorization means 10 is provided in the housing. This can, as shown in this embodiment, be designed as a cylinder lock in combination with a key. This has a locking lug 21 which can disable the alarm via a microswitch 22.
    The position sensor 5 is further connected to the data processing unit 8. The data processing unit is designed in this embodiment as a semiconductor board and includes a power supply 15 in the form of a battery. Furthermore, with the data processing unit of the signal generator 9 is connected, which is designed as a siren or optical signal generator.
    Apart from the movements caused by a displacement of the housing along the base plate, the position sensor can also detect movements such as manipulation attempts, the opening of the door and combinations of these and other operations.
    For example, if the housing 7 is separated from the base plate 6, so this is not guided and therefore arbitrary movement detected by the sensor. The signals are passed on to the data processing unit, which subsequently compares the signals with the signals of usual, permitted movements. If these signals, including the movements of the housing, deviate from the permitted signals, the signal generator 9 is activated via control signals. 4 4 - 10
    Furthermore, it can also be detected by the arrangement according to FIG. 4 if, for example, the door is opened without the doorknob, that is to say the actuating means 2, being actuated. In such cases, such as a manipulation of the trap, could also be triggered alarm.
    Another field of application of the arrangement according to the invention is to recognize violent manipulation attempts at an early stage. Usually go such
    Burglary attempts accompanied by stronger vibrations due to external violence. Even such shocks (movements with small amplitude but high speed and high accelerations) can be detected by the position sensor 5 and the sensor arrangement.
    It should be noted that the embodiment of a lever 13 which is rotatably mounted about a fulcrum 14, only one possible embodiment darsteilt. It may also be advantageous to perform the lever 13 as a spring plate, biased against the end of the Abtaststiftes 12. Further possible embodiments would be, for example, to perform the scanning pin 12 as a rack, which causes a rotation of the position sensor 5 via a gear, or to let the position sensor roll over corresponding Roilelemente directly on the base plate.
    The position sensor measures, as mentioned above, accelerations in three axes. If the sensor is rotated about an axis of rotation which passes through the sensor itself, this rotational movement can be detected due to the fact that the direction of gravitational acceleration changes with respect to the three measuring axes. In addition, the sensor can also detect changes in the acceleration due to translational movements, that is to say also acceleration due to a movement of the sensor itself.
    Now, as shown in the case of the embodiments, the sensor is positioned away from the axis of rotation of the actuating means or a lever, the sensor undergoes a rotational movement and a translational movement. This combination offers advantages, for example, when a closure element is opened by a very short and heavy blow to the actuating means. In this case, the rotational movement can only be measured in a very small time window. The translational movement, when arranged away from the axis of rotation, but in this case is excessively large and can be easily detected as a manipulation attempt. • · »» »» »» »-------
    Power can be supplied both via a local power supply (e.g., battery or rechargeable battery, etc.) and over a conventional power grid (e.g., 220V, or 12V, etc.).
    To determine the position of a sensor position sensors of different designs can be used. When existing power supply via a power grid, for example, so-called gyro sensors can be used. Preferably, however, acceleration sensors, in particular digital acceleration sensors, are used. These are based for example on the so-called MEMs technology and can measure the acceleration acting on the sensor in three axes. Thereby, static acceleration, e.g. the gravitational acceleration is detected as well as changes in the accelerations over a certain period, e.g. with non-uniform movement of the sensor or the sensor arrangement. An advantage of the technology is the very low power consumption, which in the measuring mode e.g. 40 μΑ and in standby mode e.g. 0.1 pA at an operating voltage of about 2.5V.
    The resolution of such sensors is about 10 to 20 bits, the resolution depending on the application can be selected. The supply voltage is about 2 to 4 V and the operating temperature between - ^ 40 ° C to + 85 ° C. Depending on the desired resolution, accelerations of ± 2 g, ± 4 g, ± 8 g or ± 16 g can be measured by the three-axis digital accelerometer, and the sensors can withstand high accelerations of up to 10,000 g without damage. Due to the small size (about 3x5 mm with a height of 1 mm), the installation position and installation situation can be chosen flexibly. It should also be noted that digital acceleration sensors can easily detect angular changes up to a resolution of 0.1 °. The benefits of using this sensor technology are that power consumption is very low, which greatly improves battery life and deployment capabilities. Furthermore, acceleration changes can be measured very sensitively and with high resolution. Another advantage is that digital acceleration sensors are produced in large numbers and therefore very cheaply. As an example of a sensor, the ADXL345 from Analog Devices can be named. This three-axis accelerometer with a high resolution of 13-bit measures up to 16 times the acceleration of gravity (16 g). The digital output data is given as a 16-bit two-component transmission and can be read out via an SPI (3 or - * * * 4 - 12- 4 line) or an lzC digital interface. The resolution is 4 mg / LSB and allows a measurement of angle changes below Γ.
    As a further possible sensor, the BMA020 Bosch can be used, 5 has the similar characteristics, but at a bandwidth of 25 to 1500 Hz.
    The mounting position of the sensors, in particular the mounting position of the three axes of the sensors with respect to gravity can be selected depending on the desired application. This can be done both horizontally, so that one of the measuring axes coincides with the direction of gravity, but also skew, so that all three axes or at least two in the basic position constantly measure the static acceleration of gravity and pass it on to the data processing unit.
    Furthermore, multiple position sensors can be used to compensate for example, 15 measurement errors to detect unauthorized manipulation attempts or to improve by redundancy, the security or the probability of failure. The sensors may be provided on the same element, but also be provided distributed on the arrangement. For example, a position sensor may be arranged on the closure element and one on the actuating means. With this configuration, the data processing unit could distinguish between movements of these two components.
