    The invention relates to a padlock with a lock body and a bracket, which is movable relative to the lock body between an open position and a closed position, wherein the lock body has a locking mechanism for locking the bracket in the closed position.
    The invention further relates to a
    Locking device comprising a mop trap with a preferably U-shaped bracket and a cap part and a hang in the preferably U-shaped bracket padlock.
    In a padlock of the type mentioned above, the bracket with the lock body is usually inextricably linked. In the unlocked state, however, the bracket can be moved between the open position and the closed position. In the closed position, the bracket and the lock body together form a closed loop, for example, to secure two parts together. By means of the locking mechanism, the bracket can be locked in the closed position to prevent unauthorized opening. Typically, this includes
    Locking mechanism a lock cylinder, which is rotatably operated by means of a matching key. In addition, the locking mechanism may include a driver and / or a latch.
    A typical field of application for padlocks are locking devices comprising a muzzle trap with a U-shaped bracket and a cap part. Such Überwurffallen are often found to complete cellar compartments and the like. The cap part in this case has a mostly slot-shaped recess through which passes the egg-shaped bracket in the closed state of Überwurffalle. The box is blocked by hanging in the U-shaped bracket of the bracket of a padlock and the padlock is blocked. For example, if the cap piece is attached to a door leaf and the egg-shaped bow is fastened to an associated door frame, locking the padlock will prevent the box from being opened nondestructively, so that the door through the door can not be entered.
    It is known to provide padlocks with a detection unit for detecting the closed position of the bracket. From the detection unit, a signal can be generated which indicates the closed state of the padlock. This may in particular be a visual indication on the padlock. However, it is also conceivable to transmit the signals wirelessly to a central administration or monitoring station in which, if necessary, the closed state of a large number of padlocks is detected.
    With the known detection devices, however, it is not possible to determine whether the padlock has been properly hung, for example, in the U-shaped bracket of a mop trap.
    The present invention therefore aims to develop a padlock and a locking device of the type mentioned in that in a simple manner, a check can be made whether the padlock was properly hung or whether the locking device was properly locked using the padlock.
    To solve this problem, the invention provides in a padlock of the type mentioned above, that the padlock has a capacitive proximity sensor whose measuring electrode is formed by the bracket or a part thereof. The fact that a bracket or a part of the same is used as the measuring electrode of an integrated in the padlock capacitive proximity sensor, a padlock can be equipped with great effort without the construction of a proximity sensor. The proximity sensor is suitable for detecting the proximity of a particular metallic part to the measuring electrode, i. to detect the temple of the padlock. The correct hanging of the padlock can hereby be most easily determined by the fact that the capacitive proximity sensor responds to the presence of an egg-shaped bracket of an overburden or a preferably conductive connected to this part.
    Capacitive proximity sensors are known in various embodiments. It uses the changing when approaching an object electrical capacitance of a measuring electrode to the environment or to a reference electrode. Such sensors usually work with an oscillator whose frequency-determining capacity is partially formed by the object to be detected or the environment.
    A capacitive proximity sensor in the sense of the present invention, however, also means any electrical circuit in which there is a capacitive coupling between the measuring electrode of the padlock and an external coupling electrode whose coupling property depends on the distance of the measuring electrode of the padlock from said coupling electrode.
    A preferred embodiment of the padlock according to the invention provides that the lock body or a part thereof forms a reference electrode of the proximity sensor. The provision of a second electrode in the padlock, which is electrically insulated from the measuring electrode, improves the measuring properties of the proximity sensor.
    As already mentioned, it is advantageous if a detection unit is provided for detecting the closed position of the bracket. In combination with the inventively provided proximity sensor thereby achieves complete control of the correct obstruction of a locking device in which a padlock is used, since not only can be checked whether the bracket of the padlock in the closed position, but in addition, whether the padlock properly is mounted.
    The locking mechanism of the padlock preferably comprises a mechanical and / or electronic key query. Key mechanical queries are widespread in the context of padlocks, for example in the form of lock cylinders. It is particularly preferred in the present case with regard to the fact that the inventively provided capacitive proximity sensor anyway requires a power supply, an electronic key query. A preferred development provides in this case that the electronic key query an electronic reading unit for
    Reading out identification data from a data carrier. As a data carrier, a number of known electronic keys in the form of ident media and the like. Be used. Both passively working ident media, such as RFID tags or actively working ident media, which have their own power supply, are conceivable here. The electronic key request is preferably carried out such that the padlock has an evaluation circuit for determining the access authorization on the basis of the received identification data, wherein the evaluation circuit interacts with the locking mechanism for selectively releasing or locking the bracket.
    The approximate data determined by the capacitive proximity sensor are preferably further processed in the padlock so that a signal is generated based on the measured data, which indicates the correct mounting of the padlock. The signal can be displayed for example by a visual display device on the padlock itself. Alternatively or additionally, it may be provided that a transmitting unit is provided for the wireless transmission of data, in particular the measured data of the proximity sensor and / or the detection unit. Particularly preferably, the transmitting unit is designed to transmit the data by means of capacitive coupling. The capacitive data transmission can be used here in order to realize the inventively provided function of the capacitive proximity sensor. The proximity sensor is formed in such a case, for example, as an evaluation circuit, which detects the presence or the strength of the capacitive coupling of the measuring electrode of the padlock with an external electrode.
    In this context, a preferred embodiment of the locking device according to the invention provides that the measuring electrode of the padlock as a coupling electrode of a coupling capacitance in one for the capacitive
    Data transmission set up transmitting / receiving circuit of the padlock is involved and that the Überwurffalle comprises at least one capacitive coupling surface, which is incorporated in a set up for the capacitive data transmission transmission / reception circuit of the Überwurffalle, so closes when approaching the padlock to the dodge trap an AC circuit, can be transmitted via the data between the padlock and the dungeon trap via capacitive coupling.
    The capacitive data transmission can also be used in a preferred manner to perform an identification test to determine in this way, whether that padlock, which was previously associated with the respective locking device, actually comes in the course of obstruction of the device used.
    In this case, the electrode arrangement is preferably made in such a way that the collecting rack is assigned a plate-shaped coupling component which comprises a first electrode forming the capacitive coupling surface and a second electrode. The plate-shaped coupling component can be connected in this case conductively connected to the bracket of the padlock.
    In a further preferred embodiment, it is provided that an energy converter is provided in or on the padlock with which mechanical energy can be converted into electrical energy. In a further preferred embodiment, it is provided that an energy store is provided in the padlock, which may be fed, for example, by the mentioned energy converter. The energy converter can be designed to convert, for example, vibrations, movements of the bracket of the padlock, movements of the padlock, which occur when it opens, or the rotation of a key in the padlock into electrical energy.
    The energy supply can alternatively be ensured by means of a battery, fuel cell and / or a solar cell.
    The invention will be explained in more detail with reference to an embodiment schematically illustrated in the drawing. 1 shows the padlock according to the invention, FIG. 2 shows an overburden, which can be obstructed with the aid of the padlock, and FIG. 3 shows a simplified equivalent circuit diagram of the capacitive data transmission device used in the locking device.
    In Fig. 1, a conventional padlock 1 is shown, the lock body is denoted by 2 and the bracket with 3. The padlock 1 is shown in Fig. 1 in the closed state, in which a schematically indicated locking mechanism 4 secures the bracket 3 against opening. For locking the closed position of the bracket 3, the locking device 4 has a bolt, not shown, which can interact positively in the locking position with a formed in the bracket 3 recess 5. The locking mechanism includes, for example, a lock cylinder, not shown, which can be operated by means of a mechanical key. Alternatively, the locking mechanism 4 comprises an electrically adjustable or releasable latch which engages in the recess 5. The electrically adjustable or releasable latch acts in this case with an electronically operating key query, which has a reading device for reading an identification code from an electronic key, such as a identification medium.
    If a legitimate mechanical or electronic key has been detected due to the key query, the lock of the bracket 3 is released, so that the bracket can be pulled in the direction of arrow 6 from the lock body 2 and swung to the side in sequence.
    In Fig. 2, a door leaf 7 is shown, which can be pivoted or moved relative to a stationary part, such as a door frame 8. To lock the door leaf 7 in the closed position, a mucking trap 9 is provided which has a plate-shaped component 10 fixed to the door leaf 7 with a U-shaped bracket 11 and a plate-shaped component 12 attached to the door frame 8, on which a capping member 14 via a Hinge 13 is pivotally mounted. The cap part 14 has a slot-shaped recess 15, which is penetrated in the illustrated in Fig. 2 closed state of the ÜberwurffaIle 9 of the bracket 11. If now in the bracket 11 of the bracket 3 of the padlock 1 shown in Fig. 1 is hung and the padlock is blocked, the custody box 9 can not be opened by unauthorized persons.
    FIG. 3 now shows a simplified equivalent circuit diagram of the capacitively operating proximity circuit used in the context of the invention. It can be seen that the bracket 3 of the padlock is designed as an electrode El and the lock body has an electrode E2 or acts as an electrode E2. The electrodes E1 and E2 are incorporated in a transmitting / receiving circuit 16 and preferably in a resonant circuit of the transmitting / receiving circuit 16, which is fed by a power supply 17. In order to detect whether the padlock 1 was properly hung in the closed muzzle trap 9, two schematically illustrated electrodes E3 and E4 are now arranged or formed on the plate-shaped part 12, which are electrically insulated from each other and together form a coupling capacitance. In addition, electrodes E5 and E6 can also be arranged or formed on the plate-shaped component 10, which together form a further coupling capacitance. In the correctly suspended state of the padlock, the electrode 1 is connected conductively or via a capacitive coupling to the yoke 11, so that an AC circuit is established via the electrode El, the coupling capacitance formed by the electrodes E3 and E4 or the coupling capacitance formed by the electrodes E5 and E6 and can close about the schematically indicated electric field 18 or 19 to the electrode E2. The strength of the coupling depends on how close the padlock is to the described coupling capacity of the demolition trap, so that a corresponding analysis of the coupling provides information about whether the padlock was properly hung in the closed box.
    Furthermore, the coupling between the electrodes E5 and E6 with the electrodes E3 and E4 can additionally be used as a kind of door contact, since with the door closed (preferably in the case of metal doors) the coupling is significantly better than when the door is open.
