Definitions

  • the invention relates to a safe, in particular a locker, as described in the preamble of claims 1 and 2.
  • a method for operating such a safe is also specified, as described in claims 21 and 22.
  • a disadvantage of such locker systems is that either the personnel expenditure for operating the bank lock is relatively high or, when using the currently known locks, the energy for actuating the electrically operated locks is relatively high. This requires extensive electrical installations, so that these systems are not suitable for retrofitting doors with two mechanical locks in a locker system. With such systems, all doors in the locker system would have to be replaced and their own wiring installed. The effort involved is relatively high and there is also a major problem that it is not always possible to call all customers on a certain day to find the ones stored in the lockers Outsource valuables so that the conversion can be carried out.
  • a locker system according to WO-A-89/11016 which has an additional lock, the additional lock being fastened to the door of the locker and in front of the keyhole by means of fastening means.
  • the disadvantage here is that manipulation of the additional lock cannot be ruled out by applying the additional lock to the locker.
  • the present invention is therefore based on the object to provide a locker system of the type mentioned in which the so-called bank lock can be operated remotely in a simple manner in the case of mechanically actuated locks, without requiring a high expenditure of energy.
  • An embodiment variant according to claim 3 is also advantageous, as a result of which the electromagnet only has to be acted upon over the period of time over which authorized access to the safe or locker is possible.
  • An embodiment according to claim 7 is advantageous, since additional receptacles for the coil can thereby be saved and installation in the door frame is possible in a confined space.
  • the embodiment according to claim 8 advantageously enables independent elimination of manufacturing tolerances between the electromagnet and the lock bolt. Due to the elastic intermediate elements, by means of which the electromagnet is supported on the door frame, the electromagnet can pull against the locking bar if there is an air gap, i.e. move in the direction of the locking bar, thereby eliminating the air gap and achieving a high holding force with a small electromagnet.
  • Another embodiment describes claim 9. This has the advantage that any manufacturing or dimensional tolerances can be compensated for on an electromagnet rigidly arranged in the door frame due to the mobility of the contact surface in the pulling direction of the electromagnet and the contact surface can be applied to the electromagnet without an air gap.
  • a locker system 1 with a plurality of lockers 2 is shown in a simplified schematic diagram.
  • the locker system 1 is e.g. arranged in a vault 3 of a bank 4. Access to the vault 3 is possible via an access door 5, which can be formed, for example, by a lattice door or by a reinforced door during the night.
  • a control point 7 is set up in the anteroom 6 of the vault 3 or in another room of the bank.
  • the monitor work station 8 and the card reader 9 are connected to a central control unit 11 via a data line 10, for example.
  • a log printer 12 and a further card reader 9 are also connected to this central control unit 11 in the area of the access door 5.
  • the locker system 1 is also connected to the central control unit 11 via a bus system 13 or, in the case of smaller systems, a corresponding data cable.
  • Each of the lockers 2 is closed with a door element 14, which is associated with a locking device 15.
  • This locking device 15 has a mechanical lock 16.
  • a user or owner of a locker 2 now wants to visit his locker, he must identify himself, for example at screen workstation 8, by inserting a control card made available to him in the form of a check card or the like into the card reader or a form prepared by the counter clerk filled out and signed.
  • the switch operator then has the option of entering the respective customer number or the name of the user via the screen workstation, whereupon the corresponding signature or personal data, for example a photo or the like, are presented to him on the screen, so that he can carry out a personality check. Is If the check is positive in accordance with the security regulations, the bank official can release the respective locker 2 for access by the user via the screen workstation and the central control unit 11.
  • the vault 3 he can now use his key to open the locker 2 belonging to him, whose additional lock 17, shown schematically by a box, has been unlocked via the central control unit 11 or from the workstation 8.
  • This additional lock 17 is usually referred to as a bank lock.
  • FIGS. 2 to 6 show an embodiment of a locking device 15 for a door element 14 of a locker 2.
  • These lockers 2 are installed in a body with profiles 18, which is formed from armored walls 19. Door elements are inserted between them, which in turn are fastened to the armored walls 19 via hinges 20.
  • This locking device 15 comprises a mechanical lock 16.
  • a keyhole 21 is arranged in the door element, via which a key 22 can be inserted into a locking mechanism 23.
  • the locking mechanism 23 is in movement connection with a main bolt 24.
  • the closing movement of the main bolt 24 can optionally be supported by a spring 25.
  • the lock 16 has a locking bolt 27, which can be fixed with a drive 26 if necessary, which is adjustably mounted perpendicular to the door element 14 and, like the main bolt 24, penetrates the profile 18 of the armored wall 19 in a bore 29 in a bore 29 when the lock is locked.
  • the drive 26 facing the locking bolt 27 and arranged in the profile 18 is designed, for example, as an electromagnet.
  • the locking bolt 27 is rotatably mounted on a pivot axis 30 which is arranged on the main bolt 24. In order to prevent the locking bolt 27 from moving relative to the main bolt 24 during the operation of the lock 16, the locking bolt 27 is preferred in openings 31 in a lock housing 32, which correspond to the bores 29 in the profile 18, at least in height however, in terms of height and side.
  • a locking bolt 33 Arranged between the main bolt 24 and the locking bolt 27 is a locking bolt 33 which interacts with a stop 34 provided in the lock housing 32.
  • the locking bolt 33 is also rotatable on the pivot axis 30 stored. Furthermore, it is guided in a slot or slot-shaped recess 36 via a guide pin 35 projecting in the direction of the locking bolt 27.
  • the locking bolt 33 On the side facing away from the guide pin 35, the pivot axis 30, the locking bolt 33 is connected to the locking bolt 27 via a tension spring 37, so that in the locked state of the lock 16 the locking bolt 33 assumes the position shown in full lines in FIG.
  • the drive 26 is formed by an electromagnet 38 which has a coil 39 and a U-shaped iron core 40.
  • the iron core 40 preferably consists of a plurality of dynamo sheets 41, which have a lower remanence compared to the use of a soft iron core as the iron core 40 and thereby prevent a holding force on the coil even at those times when the coil 39 is not being energized Lock bolt 27 is exercised.
  • the iron core 40 is arranged in a plane perpendicular to the blocking plane 42 indicated by a dash-dotted line. end faces 43 of the U-shaped legs are assigned flat contact surfaces 44 which are aligned parallel to the locking plane 42. A large contact area between the iron core 40 and the locking bolt 27 is thereby achieved.
  • the coil 39 is connected to the central control unit 11 via lines 45.
  • the connection can take place via a bus system or via single conductors or multiple conductors or any arbitrary line systems known from the prior art.
  • the locking bolt 33 is in the position shown in full lines in FIG. If the control point 7 tries to lock the lock 16 with the key 22 without release, the main bolt 24 moves according to an arrow 46 - FIG. 3 - in the direction of the locking mechanism 23. In this case - if the drive 26 is not activated the locking bolt 27 is taken into its position shown in full lines in FIG. 3 until it runs into the stop 34 in the position shown in broken lines.
  • the locking bar 33 is carried along, between the position shown in full and dashed lines in FIG. 3, via the pivot pin 30 and the guide pin 35 which engages in the recess 36 on the locking bar 27.
  • the relative position between the locking bolt 33 and the locking bolt 27 is fixed by the tension spring 37.
  • the locking bolt 33 If the locking bolt 33 now runs up against the stop 34, it tries to turn the locking bolt 27 counterclockwise about the pivot axis 30 via the guide pin 35. Due to the height of the locking bolt 27 in the opening 31 of the lock housing 32, the locking bolt 27 can not be rotated in the counterclockwise direction, and it is the further movement of the main bolt 24 in the direction of arrow 46 - so the pivot axis 30 in the opening direction - prevented. As can be seen from the position of an end face 47 of the main bolt 24 shown in the dashed line, this main bolt 24 is still within the bore 28 in the profile 18 of the armored wall 19 at the time when its further movement in the direction of the arrow 46 is blocked This reliably prevents the door element 14 from opening.
  • sensors 48 can be provided in the profile 18, for example, which can be connected to the central control unit 11 via a line 49. These transducers 48 can be designed both to detect unusual vibrations - such as occur during attempts to break in - or from elevated temperatures, such as occur when trying to weld the door element 14 on, for example.
  • sensors can of course also be connected to the central control unit 11 in the door element 14 via corresponding connecting lines or wireless connections.
  • the drive 26, that is to say in particular the coil 39, is supplied with current. Due to the electromagnetic force that arises between the legs of the iron core 40, the locking bolt 27, which is also made of a metal, is pulled to the end faces 43 of the iron core 40 and fixed in its position.
  • the pivot axis 30 may have a greater length than would be necessary due to the width of the locking bolt 27 of the main bolt 24 and the locking bolt 33. This makes it possible that the locking bolt 27 can assume the inclined position indicated by dashed lines - FIG. 2 - and therefore tolerance compensation between the end faces 43 of the electromagnet 38 and the contact surfaces 44 of the locking bolt 27 can take place in directions perpendicular to the locking plane 42.
  • the main bolt 24 is moved with the key 22 against the arrow 46 in the direction of the profile 18.
  • the locking bolt 27 and the locking bolt 33 are taken along via the tension spring 37 and the pivot axis 30 or the guide pin 35. Now runs the locking bolt 33 on the stop 34, it is rotated about the pivot axis 30, whereby the guide pin 35 is moved in the direction of the profile 18 and therefore there is a relative movement between the locking bolt 27 and the main bolt 24.
  • the locking bolt 27 leads the main bolt 24 slightly. This relative movement of the locking bolt 27 with respect to the main bolt 24 is terminated by a height 51 of the stop 34 or a length 52 of the elongated hole 50.
  • the relative position of the locking bolt 27 with respect to the main bolt 24 due to the guide pin 35 resulting from the rotation of the locking bolt 33 about the guide axis 30 leads to the adjustment of a stop edge 53 in the direction of the main bolt 24 by a distance 54 which is greater than the height 51, which is why the locking bar 33 can pass the stop 34.
  • the iron core 40 is inserted in a support body 56 made of plastic, which has an elastically deformable bracket projecting in the direction of the profile 18 57 can be snapped into the folded area of the profile 18.
  • An end plate 58 shown in FIGS. 2 and 6, serves as an abutment, which on the one hand delimits the opening 29 for the locking bolt 27 and, on the other hand, braces itself with an end edge 59 against an end edge 60. At the same time, this end plate 58 serves to isolate the iron core 40 from the metal profile 18.
  • this end plate 58 serves as a low-friction guide for the locking bolt 27.
  • This plastic support body 56 also favors the insulated suspension of the drive 26 in the profile 18 forming the armored wall 19. This means that additional protective measures can be dispensed with and there is also a negative influence on the Magnetic flux in the drive 26 switched off to a high degree. This can be supported by the use of special, electrically highly resistant plastics.
  • the locking bolt 27 is not blocked in its locking position, but is held back only by increased friction due to the electromagnetic field up to a maximum tensile force, after which the movement of the locking bolt 27 is released . If the remanence of the iron core 40 or the remaining residual magnetism of the drive 26 is higher than the tensile force that can be exerted on the locking bolt 27 via the main bolt 24, it may be possible that the lock is constantly blocked and only under Violence can be opened.
  • FIG. 7 the function for releasing the bank lock of the lock 16 formed by the locking bolt 27 in connection with the drive 26 is described on the basis of a block diagram of the central control unit 11.
  • the central control unit 11 comprises a computer 61, which is connected to a plurality of memories 62, 63, which can also be readable memories, for example. Furthermore, an input unit 64 and a monitoring device 65 are connected to the computer 61.
  • the computer 61 is connected to an energy source 66, to which a plurality of drives 26 for individual locks 16 are also connected. Each of these drives 26 is connected via an electronic switch 67 to a collecting line 68, which is connected via a current measuring device 69 to a return line to the energy source 66 connected is.
  • the computer 61 is connected to a bus system or a central cable via a conversion module.
  • the technical condition is checked whether the lock 16 is closed or open or whether there is a fault in the electrical system based on the current increase after the switch 67 has been closed and the drive 26 assigned to a specific lock 16 has been applied to the current measuring device 69.
  • a time measuring device is simultaneously activated, which begins with the time measurement or the counting of clock pulses.
  • the current increases according to an e-function due to the inductance formed by the coil 39. If the current exceeds one of the two switching thresholds 72 or 73, the measuring process of the time measuring device is ended.
  • the switch 67 is opened again and the current supply to the coil 39 is interrupted.
  • the time period determined is now a variable defining the operating state of the locker 2 and at the same time a measure of the inductance. If the inductance is twice as high, for example, twice the time is required to reach the switching threshold 72. Furthermore, different time ranges 74, 75, 76 are defined in one of the memories 62 and 63, respectively. If the determined time falls, for example, in the time range 74, ie the switching threshold 72 is reached over a period of up to 850 microseconds, this means that Magnetic field is not closed - the end faces 43 of the two legs of the iron core 40 are not connected via the locking bolt 27, as shown for example in FIG.
  • the determined time falls in the time range 75 between, for example, 850 to 3,000 microseconds, the inductance is very high since the magnetic field is closed by the locking bar 27, which means that a longer time is required until the current intensity has reached the switching threshold 72. Due to mechanical tolerances and a changing air gap between the end faces 43 of the iron core 40 and the locking bolt 27, the determined time in this case fluctuates between, for example, 850 to 3,000 microseconds.
  • the computer 61 issues a malfunction report to the central control unit 11 or the monitoring device 65 or a reporting and monitoring device 77 connected to it.
  • the switching threshold 73 is already exceeded in the time range 74, i.e. the current rises very quickly, it can be concluded that there is a short circuit.
  • the computer 61 reports this short circuit to the central control unit 11 or to the monitoring device 65 and switches off the system or at least the defective locker 2 for safety reasons in order to prevent damage to the installed system parts.
  • This procedure for monitoring the individual lockers 2 has the further advantage that the coil 39 exerts only a very small force on the locking bolt 27 due to the short on-time of the current and the instantaneous switch-off of the measured value determination.
  • this is advantageous to the locking bolt 27 to the ends 43 of the iron core 40 and to keep the air gap as small as possible.
  • this also makes it possible to find sufficient length with a low expenditure of energy, as a result of which undesirable heating in the area of the coils 39 or iron cores 40 is also avoided.
  • This type of query is shown in FIG. 8 with the characteristic curve 78 drawn in full lines.
  • the current strength increases, as a curve part 79 shows, from, for example, 8 mA to a predetermined switching threshold 72 within 800 microseconds.
  • the switching threshold 72 When the switching threshold 72 is reached, the current is reduced to 8 mA according to the curve part 80, as the curve part 81 shows.
  • the current After a period of 4 ms, the current is switched on again and rises again according to the curve part 79 until it has reached the switching threshold 72 again. If the two determined times of two queries carried out at 4 ms intervals now match, this result is recognized by the computer 61 as the correct result and is stored in one of the memories 62 and 63 of the central control unit 11. If the second query produces a different result after 4 ms, the result is recognized as a fault and rejected. After another 4 ms of a properly executed query, the next locker 2 is queried for its status.
  • the last determined state of the subject is always stored in the memories 62, 63 of the central control unit or the corresponding memories of the computer 61, so that the current status of any one is at any time Locker 2 can be queried. Since the operating system used is multitasking capable, it can be queried, for example, by the central control unit 11 during the current queries for the lockers 2 and displayed graphically on the monitoring device 65 or the reporting and monitoring device 77, for example a screen.
  • an alarm signal or an independent alarm can be emitted via the previously specified monitoring devices 65 or the reporting and monitoring device 77 carried out by control units or police forces.
  • the coil 39 is not only switched on briefly, as shown in the diagram in FIG. 8, but is also supplied with power over a longer period of time. As a result, the coil 39 generates such a strong magnetic field in the iron core 40 that the locking bolt 27 can be retained with sufficient holding force against the displacement effect of the main bolt 24. Thus, as explained in detail with reference to the figures described above, the main bolt 24 can be withdrawn entirely into the lock housing 32 and the door element 14 can be opened.
  • the power supply becomes 15 ms switched off to the coil 39 briefly. During this time, the power supply to the coil 39 of the locker to be checked is switched on and, as described above with the aid of the diagram in FIG. 8, measured. Then the power supply to the registered locker 2 is immediately restored.
  • the characteristic curve 85 shows the current rise and fall for a locker 2 which is closed.
  • This characteristic curve 85 is only shown schematically, because, as can be seen from the explanations for FIG. 8, a double interrogation can also take place during this time, in which case the interval between two consecutive interrogations can be, for example, only 2 to 3 ms. In this case, the characteristic curve 85 would take the form drawn in dashed lines. After 2 to 7 ms have elapsed, the coil 39 of that locker which is released for opening is again supplied with current. This again creates a current profile according to characteristic curve 84.
  • the characteristic curve 86 In the next intermediate period, in which the current supply to the coil 39 is interrupted, for example, as can be seen from the characteristic curve 86, a locker is now queried which is open, as a result of which the time until the current value rises to the switching threshold 72, as shown schematically , is lower than for the characteristic curves 85. If the central control unit 11 or the computer 61 is designed in such a way that it carries out an interrogation rhythm as was described with the aid of the diagram in FIG. 8, the characteristic curve 86 would also be in this representation Take the form indicated by dashed lines, that is to say deliver two significantly narrower peaks than, for example, characteristic curve 85, since with an open locker 2 the current rises to the threshold value 72 in a time of less than 800 microseconds.
  • interruptions in the power supply to the coils 39 lying between the characteristic curves 84 do not interfere with the possibility of opening the locker 2 registered for opening. These interruptions have the effect as if the coil 39 had not been applied to the full, but only to a reduced operating voltage. This weakening of the power of the coil 39 can therefore be compensated for by a correspondingly high selection of the operating voltage.

Description

Die Erfindung betrifft einen Safe, insbesondere ein Schließfach, wie es im Oberbegriff der Patentansprüche 1 und 2 beschrieben ist. Es wird ebenfalls ein Verfahren zur Betätigung eines solchen Safes angegeben, wie es im Patentanspruch 21 und 22 beschrieben ist.The invention relates to a safe, in particular a locker, as described in the preamble of claims 1 and 2. A method for operating such a safe is also specified, as described in claims 21 and 22.

Aus der EP-A-0 096 400 ist eine Vorrichtung der genannten Art und ein Verfahren für eine Schließfachanlage bekannt, bei welcher eines der beiden Schlösser in der Tür, nämlich das Bankschloß, über eine Fernsteuereinrichtung von einem Bankbeamten, der außerhalb der Schließfachanlage seinen Arbeitsplatz hat, freigegeben werden kann. Durch zusätzliche Sicherheitsschaltungen wird gewährleistet, daß bei einer Fehlfreigabe durch den Bankbediensteten nach kürzester Zeit die Banksperre vollautomatisch wieder einfällt, sodaß auch ein späterer Versuch eines Kunden, mit einem Falschschlüssel in ein Schließfach einzudringen, scheitert. Darüberhinaus sind zur Sicherung der Schließfachanlage vielfältige Sicherheitsmaßnahmen, wie Bewegungsmelder, Infrarotsensoren und sonstiges, angeordnet, wie dies auch bei anderen Tresoranlagen üblich ist. Nachteilig ist bei derartigen Schließfachanlagen, daß entweder der Personalaufwand zum Bedienen des Bankschlosses relativ hoch ist oder bei Verwendung der derzeit bekannten Schlösser die Energie zum Betätigen der elektrisch beaufschlagten Schlösser relativ hoch ist. Dies erfordert umfangreiche Elektroinstallationen, sodaß diese Systeme zum Nachrüsten von mit zwei mechanischen Schlössern versehenen Türen einer Schließfachanlage nicht geeignet sind. Bei derartigen Anlagen müßten in der Schließfachanlage sämtliche Türen ausgetauscht und eine eigene Verdrahtung eingebaut werden Der Aufwand dafür ist relativ hoch und außerdem besteht ein wesentliches Problem darin, daß es nicht immer gelingt, alle Kunden an einem bestimmten Tag aufzurufen, um die in den Schließfächern lagernden Wertgegenstände auszulagern, sodaß der Umbau durchgeführt werden kann.From EP-A-0 096 400 a device of the type mentioned and a method for a locker system is known, in which one of the two locks in the door, namely the bank lock, via a remote control device by a bank official who works outside the locker system has, can be released. Additional security switches ensure that if the bank clerk unauthorizedly releases the bank lock after a very short time, this means that a customer's later attempt to enter a locker with a false key also fails. In addition, various security measures, such as motion detectors, infrared sensors and other, are arranged to secure the locker system, as is also the case with other safe systems. A disadvantage of such locker systems is that either the personnel expenditure for operating the bank lock is relatively high or, when using the currently known locks, the energy for actuating the electrically operated locks is relatively high. This requires extensive electrical installations, so that these systems are not suitable for retrofitting doors with two mechanical locks in a locker system. With such systems, all doors in the locker system would have to be replaced and their own wiring installed. The effort involved is relatively high and there is also a major problem that it is not always possible to call all customers on a certain day to find the ones stored in the lockers Outsource valuables so that the conversion can be carried out.

Es sind bereits verschiedene Schließfachanlagen bekannt, die aus einer Vielzahl von Schließfächern bestehen, bei welchen jedes einzelne Schließfach mit einer eigenen Tür versehen ist und die über eine Sperrvorrichtung verschließbar ist. Derartige Schließfächer, auch Wertdepots genannt, werden vielfach in Banken eingesetzt, um Bankkunden die Einlagerung von Wertgegenständen ohne Kontrolle der Bank zu ermöglichen. Um die Sicherheit gegen ein unberechtigtes Öffnen eines Schließfaches zu erreichen, sind diese Türen meist mit zwei mechanischen Schlössern, einem sogenannten Kundenschloß und einem Bankschloß, versehen. Dadurch ist sichergestellt, daß der Kunde nur nach einem Nachweis der Zugangsberechtigung zum Schließfach dieses auch öffnen kann und daß neben dem Kundenschlüssel daher gegen unbefugtes Öffnen eine zusätzliche Sicherheit vorhanden ist. Das sogenannte Bankschloß wird dabei nach Identitätsprüfung durch einen, den Kunden begleitenden Bankbeamten aufgesperrt, worauf der Kunde mit seinem Schlüssel das Schließfach öffnen kann. Störend ist hierbei für viele Kunden, daß der gleichzeitig im Schließfachraum anwesende Bankangestellte die Transaktion des Kunden beobachten kann. Dementsprechend haben die Banken nicht zuletzt aber auch aufgrund hoher Personalkosten versucht, den Zugang zu derartigen Schließfachanlagen zu automatisieren.Various locker systems are already known, which consist of a large number of lockers, in which each individual locker has a Own door is provided and which can be closed by a locking device. Such lockers, also called security deposits, are widely used in banks to enable bank customers to store valuables without the bank's control. To achieve security against unauthorized opening of a locker, these doors are usually equipped with two mechanical locks, a so-called customer lock and a bank lock. This ensures that the customer can only open the locker after proof of access authorization and that, in addition to the customer key, there is therefore additional security against unauthorized opening. The so-called bank lock is unlocked after an identity check by a bank official accompanying the customer, whereupon the customer can open the locker with his key. It is disturbing for many customers that the bank clerk who is also present in the locker room can observe the customer's transaction. Accordingly, banks also tried to automate access to such locker systems, not least because of high personnel costs.

Weiters ist eine Schließfachanlage gemäß WO-A-89/11016 bekannt, die ein Zusatzschloß aufweist, wobei das Zusatzschloß über Befestigungsmittel auf der Tür des Schließfaches und vor dem Schlüsselloch befestigt wird. Nachteilig ist hierbei, daß durch das Aufbringen des Zusatzschlosses auf das Schließfach eine Manipulation des Zusatzschlosses nicht ausgeschlossen werden kann.Furthermore, a locker system according to WO-A-89/11016 is known which has an additional lock, the additional lock being fastened to the door of the locker and in front of the keyhole by means of fastening means. The disadvantage here is that manipulation of the additional lock cannot be ruled out by applying the additional lock to the locker.

Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, eine Schließfachanlage der eingangs genannten Art zu schaffen in der in einfacher Weise bei mechanisch betätigbaren Schlössern die sogenannte Banksperre fernbetätigbar ist, ohne daß dazu ein hoher Energieaufwand erforderlich ist.The present invention is therefore based on the object to provide a locker system of the type mentioned in which the so-called bank lock can be operated remotely in a simple manner in the case of mechanically actuated locks, without requiring a high expenditure of energy.

Diese Aufgabe der Erfindung wird durch die Merkmale der kennzeichnenden Teilen der Patentansprüche 1 bzw. und 2 gelöst. Der überraschende Vorteil dieser Lösung liegt nunmehr darin, daß es nur durch die Anordnung von elektrischen Schaltungsteilen im Türrahmen möglich ist, eine fernbetätigbare Banksperre bei einem einen Sperriegel und einen Hauptriegel aufweisendem Schloß für einen Safe, insbesondere ein Schließfach, zu erreichen. Dazu kommt, daß der Energieaufwand gering gehalten werden kann, da mit dem Sperriegel kein Schließvorgang oder Verriegelungsvorgang durchgeführt werden muß, sondern lediglich der Sperriegel über eine kurze Zeitdauer, während der Betätigung des Schlosses, beaufschlagt sein muß. Darüberhinaus wird in vorteilhafter Weise erreicht, daß kein hoher Kraftaufwand beim mechanischen Schloß erforderlich ist, da eine Vorspannung von mechanischen Elementen zur Sicherstellung der nachträglichen Fernbetätigbarkeit der Sperriegels weder beim Öffnen noch Schließen des mechanischen Schlosses erforderlich ist.This object of the invention is achieved by the features of the characterizing parts of claims 1 and 2 respectively. The surprising advantage of this solution now lies in the fact that it is only possible by the arrangement of electrical circuit parts in the door frame to achieve a remote-controlled bank lock with a lock having a locking bolt and a main bolt for a safe, in particular a locker. In addition, the energy consumption can be kept low, since no locking or locking process has to be carried out with the locking bolt, but only the locking bolt for a short time The length of time during which the lock is operated must be applied. In addition, it is advantageously achieved that no high expenditure of force is required for the mechanical lock, since a pretensioning of mechanical elements to ensure the subsequent remote operability of the locking bolt is not necessary when opening or closing the mechanical lock.

Von Vorteil ist auch eine Ausführungsvariante nach Patentanspruch 3, wodurch lediglich über die Zeitdauer, über welche ein berechtigter Zutritt zu dem Safe bzw. Schließfach möglich ist, eine Beaufschlagung des Elektromagnets erfolgen muß.An embodiment variant according to claim 3 is also advantageous, as a result of which the electromagnet only has to be acted upon over the period of time over which authorized access to the safe or locker is possible.

Bei einer Weiterbildung nach Patentanspruch 4 ist von Vorteil, daß eine größere, parallel zum Elektromagnet verlaufende Fläche des Sperriegels zur Verfügung steht, die eine höhere Kontaktfläche zum Elektromagnet ermöglicht, wodurch auch bei einem relativ kleinen Sperriegel eine entsprechende Rückhaltekraft für den Sperriegel zur Betätigung des Schlosses bei freigegebenem Safe bzw. Schließfach erzielt wird.In a further development according to claim 4, it is advantageous that a larger, parallel to the electromagnet surface of the locking bolt is available, which allows a higher contact area to the electromagnet, whereby even with a relatively small locking bolt a corresponding retaining force for the locking bolt for actuating the lock achieved with a released safe or locker.

Eine andere Weiterbildung der Erfindung ist im Patentanspruch 5 beschrieben. Der Vorteil dieser Lösung gegenüber der Verwendung eines Weicheisenkernes liegt darin, daß die Remanenz gering ist und ein unerwünschtes Zurückhalten des Sperriegel bei nicht beaufschlagtem Elektromagnet sicher ausgeschaltet ist, wodurch eine hohe Funktionssicherheit ohne zusätzliche mechanische oder elektrische Kontrollvorrichtungen möglich ist.Another development of the invention is described in claim 5. The advantage of this solution compared to the use of a soft iron core is that the remanence is low and unwanted retention of the locking bar is reliably switched off when the electromagnet is not acted on, which means that high functional reliability is possible without additional mechanical or electrical control devices.

Bei der Ausführungsform nach Patentanspruch 6 ist vorteilhaft, daß eine sichere Funktion des Elektromagneten bei einer einfachen Anordnung der Spule erzielt wird.In the embodiment according to claim 6 it is advantageous that a safe function of the electromagnet is achieved with a simple arrangement of the coil.

Vorteilhaft ist eine Ausgestaltung nach Patentanspruch 7, da dadurch zusätzliche aufnahmen für die Spule eingespart werden können und der Einbau im Türrahmen auf engstem Raum möglich ist.An embodiment according to claim 7 is advantageous, since additional receptacles for the coil can thereby be saved and installation in the door frame is possible in a confined space.

Die Ausgestaltung nach Patentanspruch 8 ermöglicht auf vorteilhafte Weise eine selbständige Beseitigung von Fertigungstoleranzen zwischen dem Elektromagneten und dem Sperriegel. Durch die elastischen Zwischenglieder, über die der Elektromagnet am Türrahmen abgestützt ist, kann sich der Elektromagnet bei einem vorhandenen Luftspalt an den Sperriegel heranziehen, also in Richtung des Sperriegel, bewegen dadurch kann der Luftspalt beseitigt und eine hohe Haltekraft mit einem kleinen Elektromagnet erzielt werden.The embodiment according to claim 8 advantageously enables independent elimination of manufacturing tolerances between the electromagnet and the lock bolt. Due to the elastic intermediate elements, by means of which the electromagnet is supported on the door frame, the electromagnet can pull against the locking bar if there is an air gap, i.e. move in the direction of the locking bar, thereby eliminating the air gap and achieving a high holding force with a small electromagnet.

Eine andere Ausgestaltung beschreibt Patentanspruch 9. Diese hat den Vorteil, daß auf einem im Türrahmen starr angeordneten Elektromagneten durch die Beweglichkeit der Anlagefläche in Anzugrichtung des Elektromagneten eventuelle Fertigungs- bzw. Maßtoleranzen ausgeglichen und die Anlagefläche luftspaltfrei am Elektromagnet angelegt werden kann.Another embodiment describes claim 9. This has the advantage that any manufacturing or dimensional tolerances can be compensated for on an electromagnet rigidly arranged in the door frame due to the mobility of the contact surface in the pulling direction of the electromagnet and the contact surface can be applied to the electromagnet without an air gap.

Weitere Vorteile zu den folgenden Patentansprüchen sind in der nachfolgenden Beschreibung angegeben.Further advantages to the following claims are given in the description below.

Die Erfindung wird im nachfolgenden anhand der in den Zeichnungen gezeigten Ausführungsbeispiele näher erläutert.The invention is explained in more detail below with reference to the exemplary embodiments shown in the drawings.

In Fig.1 ist eine Schließfachanlage 1 mit einer Vielzahl von Schließfächern 2 in vereinfachter schematischer schaubildlicher Darstellung gezeigt. Die Schließfachanlage 1 ist z.B. in einem Tresorraum 3 einer Bank 4 angeordnet. Der Zutritt zum Tresorraum 3 ist über eine Zugangstür 5, die beispielsweise durch eine Gittertür oder während der Nachtstunden durch eine Panzertür gebildet sein kann, möglich. Um den Zugang zur Schließfachanlage 1 zu ermöglichen, ist im Vorraum 6 des Tresorraums 3 oder in einem anderen Raum der Bank eine Kontrollstelle 7 eingerichtet. Diese umfaßt einen Bildschirmarbeitsplatz 8 und gegebenenfalls in Kartenlesegerät 9. Der Bildschirrnarbeitsplatz 8 und das Kartenlesegerät 9 sind beispielsweise über eine Datenleitung 10 mit einer Zentralsteuereinheit 11 verbunden. An diese Zentralsteuereinheit 11 ist weiters ein Protokolldrucker 12 und ein weiteres Kartenlesegerät 9 im Bereich der Zugangstür 5 angeschlossen. Über ein Bussystem 13, oder bei kleineren Anlagen ein entsprechendes Datenkabel, ist die Schließfachanlage 1 ebenfalls mit der Zentralsteuereinheit 11 verbunden. Jedes der Schließfächer 2 ist mit einem Türelement 14 verschlossen, der eine Sperreinrichtung 15 zugeordnet ist. Diese Sperreinrichtung 15 weist ein mechanisches Schloß 16 auf.In Figure 1, a locker system 1 with a plurality of lockers 2 is shown in a simplified schematic diagram. The locker system 1 is e.g. arranged in a vault 3 of a bank 4. Access to the vault 3 is possible via an access door 5, which can be formed, for example, by a lattice door or by a reinforced door during the night. To enable access to the locker system 1, a control point 7 is set up in the anteroom 6 of the vault 3 or in another room of the bank. This includes a monitor work station 8 and possibly in a card reader 9. The monitor work station 8 and the card reader 9 are connected to a central control unit 11 via a data line 10, for example. A log printer 12 and a further card reader 9 are also connected to this central control unit 11 in the area of the access door 5. The locker system 1 is also connected to the central control unit 11 via a bus system 13 or, in the case of smaller systems, a corresponding data cable. Each of the lockers 2 is closed with a door element 14, which is associated with a locking device 15. This locking device 15 has a mechanical lock 16.

Will nun ein Benutzer oder Inhaber eines Schließfaches 2 sein Schließfach aufsuchen, so muß er sich, beispielsweise beim Bildschirmarbeitsplatz 8 ausweisen, indem er eine ihm zur Verfügung gestellte Kontrollkarte in Art einer Scheckkarte oder dgl. in den Kartenleser einführt bzw. ein vom Schalterbeamten vorbereitetes Formular ausfüllt und unterzeichnet. Der Schalterbearnte hat dann die Möglichkeit, über den Bildschirmarbeitsplatz die jeweilige Kundennummer oder den Namen des Benutzers einzugeben, worauf ihm auf dem Bildschirm die entsprechende Unterschrift oder personenbezogene Daten, beispielsweise ein Foto oder dgl., präsentiert werden, sodaß er einer Persönlichkeitskontrolle vornehmen kann. Ist die Überprüfung den Sicherheitsbestimmungen entsprechend positiv verlaufen, kann der Bankbeamte über den Bildschirmarbeitsplatz und die Zentralsteuereinheit 11 das jeweilige Schließfach 2 für den Zugang durch den Benutzer freigegeben. Der Benutzer begibt sich dann in den Bereich der Zugangstür 5, wo er gegebenenfalls nach nochmaliger Überprüfung der Zutrittsberechtigung unter Benützung des Kartenlesegerätes 9 Zugang zum Tresorraum 3 erhält. Im Tresorraum 3 kann er nun mit seinem Schlüssel das ihm gehörende Schließfach 2, dessen schematisch durch ein Kästchen dargestelltes Zusatzschloß 17 über die Zentralsteuereinheit 11 bzw. vom Bildschirmarbeitsplatz 8 entriegelt wurde, öffnen. Dieses Zusatzschloß 17 wird üblicherweise als Banksperre bezeichnet.If a user or owner of a locker 2 now wants to visit his locker, he must identify himself, for example at screen workstation 8, by inserting a control card made available to him in the form of a check card or the like into the card reader or a form prepared by the counter clerk filled out and signed. The switch operator then has the option of entering the respective customer number or the name of the user via the screen workstation, whereupon the corresponding signature or personal data, for example a photo or the like, are presented to him on the screen, so that he can carry out a personality check. Is If the check is positive in accordance with the security regulations, the bank official can release the respective locker 2 for access by the user via the screen workstation and the central control unit 11. The user then goes into the area of the access door 5, where he or she may have access to the vault 3 after having checked the access authorization again using the card reader 9. In the vault 3, he can now use his key to open the locker 2 belonging to him, whose additional lock 17, shown schematically by a box, has been unlocked via the central control unit 11 or from the workstation 8. This additional lock 17 is usually referred to as a bank lock.

In den Fig.2 bis 6 ist eine Ausführung einer Sperreinrichtung 15 für ein Türelement 14 eines Schließfaches 2 dargestellt. Diese Schließfächer 2 sind in einen Korpus mit Profilen 18 eingebaut, der aus Panzerwänden 19 gebildet ist. Zwischen diesen sind Türelementen eingesetzt, die ihrerseits an den Panzerwänden 19 über Scharniere 20 befestigt sind. Diese Sperreinrichtung 15 umfaßt ein mechanisches Schloß 16. Zur Betätigung des mechanischen Schlosses 16 ist in dem Türelement ein Schlüsselloch 21 angeordnet, über welches ein Schlüssel 22 in eine Schließmechanik 23 eingeführt werden kann. Die Schließmechanik 23 steht mit einem Hauptriegel 24 in Bewegungsverbindung. Die Schließbewegung des Hauptriegels 24 kann gegebenenfalls durch eine Feder 25 unterstützt werden. Das Schloß 16 weist einen mit einem Antrieb 26 bedarfsweise festhaltbaren Sperriegel 27 auf, der senkrecht zum Türelement 14 verstellbar gelagert ist und ebenso wie der Hauptriegel 24 in einer Bohrung 28 das Profil 18 der Panzerwand 19 in einer Bohrung 29 bei gesperrtem Schloß durchdringt. Der dem Sperriegel 27 zugewandte und im Profil 18 angeordnete Antrieb 26 ist beispielsweise als Elektromagnet ausgebildet. Der Sperriegel 27 ist auf einer Schwenkachse 30, die am Hauptriegel 24 angeordnet ist, drehbar gelagert. Um zu verhindem, daß sich der Sperriegel 27 während des Betriebes des Schlosses 16 gegenüber dem Hauptriegel 24 verschieben kann, ist der Sperriegel 27 in Durchbrüchen 31 in einem Schloßgehäuse 32, die mit den Bohrungen 29 im Profil 18 korrespondieren, zumindest der Höhe nach, bevorzugt jedoch der Höhe und Seite nach, geführt sind.2 to 6 show an embodiment of a locking device 15 for a door element 14 of a locker 2. These lockers 2 are installed in a body with profiles 18, which is formed from armored walls 19. Door elements are inserted between them, which in turn are fastened to the armored walls 19 via hinges 20. This locking device 15 comprises a mechanical lock 16. To actuate the mechanical lock 16, a keyhole 21 is arranged in the door element, via which a key 22 can be inserted into a locking mechanism 23. The locking mechanism 23 is in movement connection with a main bolt 24. The closing movement of the main bolt 24 can optionally be supported by a spring 25. The lock 16 has a locking bolt 27, which can be fixed with a drive 26 if necessary, which is adjustably mounted perpendicular to the door element 14 and, like the main bolt 24, penetrates the profile 18 of the armored wall 19 in a bore 29 in a bore 29 when the lock is locked. The drive 26 facing the locking bolt 27 and arranged in the profile 18 is designed, for example, as an electromagnet. The locking bolt 27 is rotatably mounted on a pivot axis 30 which is arranged on the main bolt 24. In order to prevent the locking bolt 27 from moving relative to the main bolt 24 during the operation of the lock 16, the locking bolt 27 is preferred in openings 31 in a lock housing 32, which correspond to the bores 29 in the profile 18, at least in height however, in terms of height and side.

Zwischen dem Hauptriegel 24 und dem Sperriegel 27 ist ein Arretierriegel 33 angeordnet, der mit einem im Schloßgehäuse 32 vorgesehenen Anschlag 34 zusammenwirkt. Der Arretierriegel 33 ist ebenfalls auf der Schwenkachse 30 drehbar gelagert. Weiters ist er über einen in Richtung des Sperriegels 27 vorspringenden Führungszapfen 35 in einem Langloch bzw. einer langlochförmigen Ausnehmung 36 geführt. Auf der vom Führungszapfen 35 abgewendeten Seite, der Schwenkachse 30, ist der Arretierriegel 33 über eine Zugfeder 37 mit dem Sperriegel 27 verbunden, sodaß im gesperrten Zustand des Schlosses 16 der Arretierriegel 33 die, in Fig.3 in vollen Linien gezeichnete Stellung einnimmt.Arranged between the main bolt 24 and the locking bolt 27 is a locking bolt 33 which interacts with a stop 34 provided in the lock housing 32. The locking bolt 33 is also rotatable on the pivot axis 30 stored. Furthermore, it is guided in a slot or slot-shaped recess 36 via a guide pin 35 projecting in the direction of the locking bolt 27. On the side facing away from the guide pin 35, the pivot axis 30, the locking bolt 33 is connected to the locking bolt 27 via a tension spring 37, so that in the locked state of the lock 16 the locking bolt 33 assumes the position shown in full lines in FIG.

Der Antrieb 26 ist durch einen Elektromagnet 38 gebildet, der eine spule 39 und einen U-förmig ausgebildeten Eisenkem 40 aufweist. Der Eisenkern 40 besteht bevorzugt aus einer Mehrzahl von Dynamoblechen 41, die gegenüber der Verwendung eines Weicheisenkernes als Eisenkern 40 eine geringere Remanenz aufweisen und dadurch verhindern, daß auch zu jenen Zeiten, zu welchen die Spule 39 nicht mit Energie beaufschlagt wird, eine Haltekraft auf den Sperriegel 27 ausgeübt wird. Wie ersichtlich, ist der Eisenkern 40 in einer zur, durch eine strichpunktierte Linie angedeutete Sperrebene 42 senkrecht verlaufenden Ebene angeordnet. stirnseiten 43 der U-förmigen Schenkel sind ebene Anlageflächen 44, die parallel zur Sperrebene 42 ausgerichtet sind, zugeordnet. Dadurch wird eine große Kontaktfläche zwischen dem Eisenkern 40 und dem Sperriegel 27 erreicht.The drive 26 is formed by an electromagnet 38 which has a coil 39 and a U-shaped iron core 40. The iron core 40 preferably consists of a plurality of dynamo sheets 41, which have a lower remanence compared to the use of a soft iron core as the iron core 40 and thereby prevent a holding force on the coil even at those times when the coil 39 is not being energized Lock bolt 27 is exercised. As can be seen, the iron core 40 is arranged in a plane perpendicular to the blocking plane 42 indicated by a dash-dotted line. end faces 43 of the U-shaped legs are assigned flat contact surfaces 44 which are aligned parallel to the locking plane 42. A large contact area between the iron core 40 and the locking bolt 27 is thereby achieved.

Über Leitungen 45 ist die Spule 39 mit der Zentralsteuereinheit 11 verbunden. Die Verbindung kann über ein Bussystem oder über Einzelleiter oder Mehrfachleiter bzw. alle beliebigen, aus dem Stand der Technik bekannten Leitungssysteme erfolgen.The coil 39 is connected to the central control unit 11 via lines 45. The connection can take place via a bus system or via single conductors or multiple conductors or any arbitrary line systems known from the prior art.

Wie nun besser aus der Zusammenschau der Fig.2 bis 4 zu entnehmen ist, befindet sich bei versperrten Schloß 16 der Arretierriegel 33 in der in Fig.3 in vollen Linien gezeichneten Stellung. Wird nun ohne Freigabe von der Kontrollstelle 7 versucht, das Schloß 16 mit dem Schlüssel 22 zu sperren, so bewegt sich der Hauptriegel 24 entsprechend einem Pfeil 46 - Fig.3 - in Richtung der Schließmechanik 23. Dabei wird - wenn der Antrieb 26 nicht aktiviert ist - der Sperriegel 27 in seine in vollen Linien in Fig.3 gezeigten Position mitgenommen, bis er in der in strichlierten Linien eingetragenen Position auf den Anschlag 34 aufläuft. Die Mitnahme des Arretierriegels 33, zwischen der in Fig.3 in vollen und strichlierten gezeigten Position erfolgt, über den Schwenkzapfen 30 und den Führungszapfen 35 der in die Ausnehmung 36 am Sperriegel 27 eingreift. Die Relativlage zwischen dem Arretierriegel 33 und dem Sperriegel 27 wird dabei durch die Zugfeder 37 fixiert.As can now be seen better from the overview of FIGS. 2 to 4, when the lock 16 is locked, the locking bolt 33 is in the position shown in full lines in FIG. If the control point 7 tries to lock the lock 16 with the key 22 without release, the main bolt 24 moves according to an arrow 46 - FIG. 3 - in the direction of the locking mechanism 23. In this case - if the drive 26 is not activated the locking bolt 27 is taken into its position shown in full lines in FIG. 3 until it runs into the stop 34 in the position shown in broken lines. The locking bar 33 is carried along, between the position shown in full and dashed lines in FIG. 3, via the pivot pin 30 and the guide pin 35 which engages in the recess 36 on the locking bar 27. The relative position between the locking bolt 33 and the locking bolt 27 is fixed by the tension spring 37.

Läuft nun der Arretierriegel 33 am Anschlag 34 auf, so versucht er, den Sperriegel 27 über den Führungszapfen 35 um die Schwenkachse 30 entgegen dem Uhrzeigersinn zu verdrehen. Durch die höhenmäßige Führung des Sperriegels 27 in dem Durchbruch 31 des Schloßgehäuses 32, kann der Sperriegel 27 jedoch in Richtung entgegen dem Uhrzeigersinn nicht verdreht werden, und es wird dadurch über die Schwenkachse 30 die weitere Bewegung des Hauptriegels 24 in Richtung des Pfeils 46 - also in Öffnungsrichtung - unterbunden. Wie aus der in den strichlierten Darstellung gezeigten Lage einer Stirnseite 47 des Hauptriegels 24 zu entnehmen ist, befindet sich dieser Hauptriegel 24 zum Zeitpunkt in dem seine weitere Bewegung in Richtung des Pfeils 46 blockiert wird, noch innerhalb der Bohrung 28 im Profil 18 der Panzerwand 19. Damit ist ein Öffnen des Türelementes 14 zuverlässig verhindert.If the locking bolt 33 now runs up against the stop 34, it tries to turn the locking bolt 27 counterclockwise about the pivot axis 30 via the guide pin 35. Due to the height of the locking bolt 27 in the opening 31 of the lock housing 32, the locking bolt 27 can not be rotated in the counterclockwise direction, and it is the further movement of the main bolt 24 in the direction of arrow 46 - so the pivot axis 30 in the opening direction - prevented. As can be seen from the position of an end face 47 of the main bolt 24 shown in the dashed line, this main bolt 24 is still within the bore 28 in the profile 18 of the armored wall 19 at the time when its further movement in the direction of the arrow 46 is blocked This reliably prevents the door element 14 from opening.

Das Türelement 14 kann daher lediglich durch einen gewaltsamen Öffnungsvorgang geöffnet werden. Um diesen zu erkennen bzw. ein Aufbrechen des Türelementes 14 zu verhindem, können beispielsweise im Profil 18, Meßwertgeber 48 vorgesehen sein, die über eine Leitung 49 mit der Zentralsteuereinheit 11 verbunden sein können. Diese Meßwertgeber 48 können sowohl zum Feststellen von außerüblichen Erschütterungen - wie diese bei Einbruchsversuchen auftreten - oder von erhöhten Temperaturen, wie sie beispielsweise beim Versuch, das Türelement 14 aufzuschweißen, entstehen, ausgebildet sein.The door element 14 can therefore only be opened by a violent opening process. In order to recognize this or to prevent the door element 14 from breaking open, sensors 48 can be provided in the profile 18, for example, which can be connected to the central control unit 11 via a line 49. These transducers 48 can be designed both to detect unusual vibrations - such as occur during attempts to break in - or from elevated temperatures, such as occur when trying to weld the door element 14 on, for example.

Selbstverständlich ist es auch möglich, jedwede andere Sicherungsvorrichtung vorzusehen. So können Meßwertgeber natürlich auch im Türelement 14 über entsprechende Verbindungsleitungen oder drahtlose Verbindungen mit der Zentralsteuereinheit 11 verbunden sein.Of course, it is also possible to provide any other safety device. For example, sensors can of course also be connected to the central control unit 11 in the door element 14 via corresponding connecting lines or wireless connections.

Soll hingegen das Türelement 14 durch einen berechtigten Benutzer geöffnet werden, so wird der Antrieb 26, also insbesondere die Spule 39, mit Strom versorgt. Durch die entstehende elektromagnetische Kraft zwischen den Schenkeln des Eisenkernes 40, wird der ebenfalls aus einem Metall bestehende Sperriegel 27 an die Stirnseiten 43 des Eisenkernes 40 herangezogen und in seiner Position fixiert. Um eventuelle Maßungenauigkeiten bzw. Fertigungstoleranzen bei der Montage des Sperriegel 27 bzw. des Antriebes 26 auszugleichen, kann wie dies in Fig.2 schematisch angedeutet ist, die Schwenkachse 30 eine größere Länge aufweisen als dies aufgrund der Breite des Sperriegels 27 des Hauptriegels 24 und des Arretierriegels 33 notwendig wäre. Dadurch ist es möglich, daß der Sperriegel 27 die mit strichlierte Linien angedeutete Schrägstellung - Fig.2 - einnehmen kann und daher in senkrecht zur Sperrebene 42 verlaufenden Richtungen ein Toleranzausgleich zwischen den Stirnseiten 43 des Elektromagneten 38 und den Anlageflächen 44 des Sperriegels 27 erfolgen kann.If, on the other hand, the door element 14 is to be opened by an authorized user, the drive 26, that is to say in particular the coil 39, is supplied with current. Due to the electromagnetic force that arises between the legs of the iron core 40, the locking bolt 27, which is also made of a metal, is pulled to the end faces 43 of the iron core 40 and fixed in its position. For possible dimensional inaccuracies or manufacturing tolerances at To compensate for the assembly of the locking bolt 27 or the drive 26, as is indicated schematically in FIG. 2, the pivot axis 30 may have a greater length than would be necessary due to the width of the locking bolt 27 of the main bolt 24 and the locking bolt 33. This makes it possible that the locking bolt 27 can assume the inclined position indicated by dashed lines - FIG. 2 - and therefore tolerance compensation between the end faces 43 of the electromagnet 38 and the contact surfaces 44 of the locking bolt 27 can take place in directions perpendicular to the locking plane 42.

Die Funktion des Schlosses 16 beim berechtigten Aufsperren ist nun folgendermaßen:The function of the lock 16 for authorized unlocking is now as follows:

Nach dem Einsetzen des Schlüssels 22 in die Schließmechanik 23 und dem Herumdrehen desselben, wird auf den Hauptriegel 24 eine in Richtung des Pfeiles 46 wirkende Zugkraft ausgeübt Dadurch bewegt sich die Schwenkachse 30 ebenfalls in Richtung des Pfeils 46. Nachdem der Sperriegel 27 in seiner Position, nunrnehr jedoch durch den Antrieb 26 fixiert ist, wird der Hauptriegel 24 entgegen der Wirkung der Zugfeder 37 relativ zum Sperriegel 27 in Richtung des Pfeils 46 bewegt. Dadurch verschiebt sich auch die Schwenkachse 30 in einem parallel zum Hauptriegel 24 sich erstreckenden Langloch 50 bis in die in Fig.4 in vollen Linien gezeigte Stellung. Nachdem der Arretierriegel 33 jedoch im wesentlichen spielfrei auf der Schwenkachse 30 drehbar gelagert ist, wird mittels dieses Führungszapfens 35, welcher durch die Ausnehmung 36 im Sperriegel 27 in seiner Position festgehalten wird, der Arretierriegel 33 um den Schwenkachse 30 in die in Fig.4 in vollen Linien gezeigte Stellung verschwenkt.After inserting the key 22 into the locking mechanism 23 and turning it around, a tensile force acting in the direction of the arrow 46 is exerted on the main bolt 24. As a result, the pivot axis 30 also moves in the direction of the arrow 46. After the locking bolt 27 in its position, now however fixed by the drive 26, the main bolt 24 is moved against the action of the tension spring 37 relative to the locking bolt 27 in the direction of arrow 46. As a result, the pivot axis 30 also shifts in an elongated hole 50 extending parallel to the main bolt 24 to the position shown in full lines in FIG. After the locking bolt 33 is rotatably mounted on the pivot axis 30 essentially without play, by means of this guide pin 35, which is held in position by the recess 36 in the locking bolt 27, the locking bolt 33 about the pivot axis 30 in the in FIG Position shown in full lines pivoted.

In dieser verschwenkten Stellung des Arretierriegels 33 befindet sich dieser oberhalb des Anschlages 34 und die Schwenkachse 30 liegt an dem der Schließmechanik 23 zugewendeten Stirnende des Langloches 50 an. Dadurch wird nunmehr die volle, durch die Schließmechanik auf den Hauptriegel 24 ausgeübte Zugkraft über die Schwenkachse 30 auch auf den Sperriegel 27 übertragen. Ist nun die Haftkraft des Antriebes 26 derart bemessen, daß die in Richtung des Pfeils 46 mit dem Schlüssel 22 aufgebrachte Zugkraft größer ist, so wird der Sperriegel 27 entgegen der Haftkraft des Antriebes 26 in das Schloßgehäuse 32 zurückgezogen, sodaß sich sowohl der Hauptriegel 24 als auch der Sperriegel 27 aus den Öffnungen 28 und 29 im Profil 18 zurückziehen und die Bewegung des Türelementes 14 freigeben.In this pivoted position of the locking bolt 33, the latter is located above the stop 34 and the pivot axis 30 lies against the end face of the elongated hole 50 facing the locking mechanism 23. As a result, the full tensile force exerted by the locking mechanism on the main bolt 24 is now also transmitted to the locking bolt 27 via the pivot axis 30. If the adhesive force of the drive 26 is dimensioned such that the tensile force applied in the direction of arrow 46 with the key 22 is greater, the locking bolt 27 is withdrawn against the adhesive force of the drive 26 in the lock housing 32, so that both the main bolt 24 and also withdraw the locking bolt 27 from the openings 28 and 29 in the profile 18 and the movement of the Release door element 14.

Dies ist insbesondere deshalb möglich, da die Bewegung des Haupt- und Sperriegel 24,27 durch den Arretierriegel 33 nicht mehr behindert ist, nachdem sich dieser oberhalb des Anschlages 34 befindet.This is possible in particular because the movement of the main and locking bolt 24, 27 is no longer hindered by the locking bolt 33 after it is above the stop 34.

Ist die Öffnungsbewegung des Hauptriegels 24 in Richtung des Pfeiles 46 beendet, so schnappt der Arretierriegel 33 aufgrund der Wirkung der Zugfeder 37 in die in Fig.4 in strichlierten Linien gezeigte Stellung zurück.If the opening movement of the main bolt 24 in the direction of the arrow 46 has ended, the locking bolt 33 snaps back into the position shown in broken lines in FIG. 4 due to the action of the tension spring 37.

Soll nun das Schließfach 2 durch den berechtigten Benutzer wieder verschlossen werden, so wird der Hauptriegel 24 mit dem Schlüssel 22 entgegen dem Pfeil 46 in Richtung des Profils 18 bewegt. Über die Zugfeder 37 und die Schwenkachse 30 bzw. den Führungszapfen 35 wird der Sperriegel 27 und der Arretierriegel 33 mitgenommen. Läuft nun der Arretierriegel 33 auf den Anschlag 34 auf, so wird er um die Schwenkachse 30 verdreht, wodurch der Führungszapfen 35 in Richtung des Profils 18 bewegt wird und es daher zu einer Relativbewegung zwischen dem Sperriegel 27 und dem Hauptriegel 24 kommt. Dadurch eilt der Sperriegel 27 dem Hauptriegel 24 geringfügig vor. Diese Relativbewegung des Sperriegels 27 gegenüber dem Hauptriegel 24 wird durch eine Höhe 51 des Anschlages 34 bzw. eine Länge 52 des Langloches 50 beendet. Die sich aus der Verdrehung des Arretierriegels 33 um die Führungsachse 30 ergebende Relativstellung des Sperriegels 27 gegenüber dem Hauptriegel 24 aufgrund des Führungszapfens 35 führt zur Verstellung einer Anschlagkante 53 in Richtung des Hauptriegels 24 um eine Distanz 54, die größer ist als die Höhe 51, weshalb der Arretierriegel 33 den Anschlag 34 passieren kann.If the locker 2 is now to be closed again by the authorized user, the main bolt 24 is moved with the key 22 against the arrow 46 in the direction of the profile 18. The locking bolt 27 and the locking bolt 33 are taken along via the tension spring 37 and the pivot axis 30 or the guide pin 35. Now runs the locking bolt 33 on the stop 34, it is rotated about the pivot axis 30, whereby the guide pin 35 is moved in the direction of the profile 18 and therefore there is a relative movement between the locking bolt 27 and the main bolt 24. As a result, the locking bolt 27 leads the main bolt 24 slightly. This relative movement of the locking bolt 27 with respect to the main bolt 24 is terminated by a height 51 of the stop 34 or a length 52 of the elongated hole 50. The relative position of the locking bolt 27 with respect to the main bolt 24 due to the guide pin 35 resulting from the rotation of the locking bolt 33 about the guide axis 30 leads to the adjustment of a stop edge 53 in the direction of the main bolt 24 by a distance 54 which is greater than the height 51, which is why the locking bar 33 can pass the stop 34.

Nach dem Passieren des Anschlages 34 durch den Arretierriegel 33 schnappt dieser aufgrund der Wirkung der Zugfeder 37 wieder in seine aus Fig.3 ersichtliche Ruhestellung zurück.After passing the stop 34 by the locking bolt 33, this snaps back into its rest position shown in FIG. 3 due to the action of the tension spring 37.

Aus den Darstellungen in Fig.5 und 6 ist weiters zu ersehen, daß die Spule 39 nur einem Schenkel 55 des U-förmigen ausgebildeten Eisenkernes 40 zugeordnet ist.From the representations in FIGS. 5 and 6 it can further be seen that the coil 39 is assigned to only one leg 55 of the U-shaped iron core 40.

Der Eisenkern 40 ist in einem Tragkörper 56 aus Kunststoff eingesetzt, der mit einem in Richtung des Profils 18 vorspringenden, elastisch verformbaren Bügel 57 in den gekanteten Bereich des Profils 18 einschnappbar ist. Als Widerlager dient eine Stirnplatte 58, - in Fig.2 und 6 dargestellt - die einerseits die Öffnung 29 für den Sperriegel 27 begrenzt und andererseits sich mit einer Stirnkante 59 gegen eine Stirnkante 60 verspannt. Gleichzeitig dient diese Stirnplatte 58 zur Isolierung des Eisenkemes 40 von dem aus Metall bestehenden Profil 18.The iron core 40 is inserted in a support body 56 made of plastic, which has an elastically deformable bracket projecting in the direction of the profile 18 57 can be snapped into the folded area of the profile 18. An end plate 58, shown in FIGS. 2 and 6, serves as an abutment, which on the one hand delimits the opening 29 for the locking bolt 27 and, on the other hand, braces itself with an end edge 59 against an end edge 60. At the same time, this end plate 58 serves to isolate the iron core 40 from the metal profile 18.

Gleichzeitig dient diese Stirnplatte 58 als reibungsarme Führung für den Sperriegel 27. Dieser Tragkörper 56 aus Kunststoff begünstigt gleichzeitig die isolierte Aufhängung des Antriebes 26 in dem die Panzerwand 19 bildenden Profils 18. Damit kann auf zusätzliche Schutzmaßnahmen verzichtet werden und es ist außerdem eine negative Beeinflußung des Magnetflusses im Antrieb 26 im hohen Maße ausgeschaltet. Dies kann durch die Verwendung spezieller elektrisch hoch widerstandsfähiger Kunststoffe noch unterstützt werden.At the same time, this end plate 58 serves as a low-friction guide for the locking bolt 27. This plastic support body 56 also favors the insulated suspension of the drive 26 in the profile 18 forming the armored wall 19. This means that additional protective measures can be dispensed with and there is also a negative influence on the Magnetic flux in the drive 26 switched off to a high degree. This can be supported by the use of special, electrically highly resistant plastics.

Wesentlich für die erfindungsgemäße Funktion des Schlosses 16 ist, daß der Sperriegel 27 in seiner sperrenden Stellung nicht blockiert wird, sondem nur durch eine erhöhte Reibung aufgrund des elektromagnetischen Feldes bis zu einer maximalen Zugkraft zurückgehalten wird, nach deren Überschreitung die Bewegung des Sperriegels 27 freigegeben ist. Ist nämlich die Remanenz des Eisenkernes 40 bzw. der verbleibende Restmagnetismus des Antriebes 26 höher als die Zugkraft, die über den Hauptriegel 24 auf den Sperriegel 27 ausgeübt werden kann, so ist es unter Umständen möglich, daß das Schloß ständig blockiert wird und nur mehr unter Gewaltanwendung geöffnet werden kann.It is essential for the function of the lock 16 according to the invention that the locking bolt 27 is not blocked in its locking position, but is held back only by increased friction due to the electromagnetic field up to a maximum tensile force, after which the movement of the locking bolt 27 is released . If the remanence of the iron core 40 or the remaining residual magnetism of the drive 26 is higher than the tensile force that can be exerted on the locking bolt 27 via the main bolt 24, it may be possible that the lock is constantly blocked and only under Violence can be opened.

In Fig.7 ist anhand eines Bockschaltbildes der Zentralsteuereinheit 11 die Funktion zur Freigabe der durch den Sperriegel 27 in Verbindung mit dem antrieb 26 gebildeten Banksperre des Schlosses 16 beschrieben.In FIG. 7, the function for releasing the bank lock of the lock 16 formed by the locking bolt 27 in connection with the drive 26 is described on the basis of a block diagram of the central control unit 11.

Die Zentralsteuereinheit 11 umfaßt einen Rechner 61, der mit mehreren Speichern 62,63, bei welchen es sich beispielsweise auch nur um lesbare Speicher handeln kann, verbunden. Desweiteren ist an dem Rechner 61 eine Eingabeeinheit 64 und eine Überwachungsvorrichtung 65 angeschlossen. Der Rechner 61 ist mit einer Energiequelle 66 verbunden, an der auch eine Vielzahl von Antrieben 26, für einzelne Schlösser 16, angeschlossen sind. Jeder dieser Antriebe 26 ist über einen elektronischen Schalter 67 mit einer Sammelleitung 68 verbunden, die über eine Strommeßvorrichtung 69 mit einer Rückleitung zur Energiequelle 66 verbunden ist. Überdies ist der Rechner 61 über einen Umsetzbaustein mit einem Bussystem oder einem Zentralkabel verbunden. die Funktion der Zentralsteuereinheit 11 soll nun anhand der Diagramme in Fig.8 und 9 näher erläutert werden.The central control unit 11 comprises a computer 61, which is connected to a plurality of memories 62, 63, which can also be readable memories, for example. Furthermore, an input unit 64 and a monitoring device 65 are connected to the computer 61. The computer 61 is connected to an energy source 66, to which a plurality of drives 26 for individual locks 16 are also connected. Each of these drives 26 is connected via an electronic switch 67 to a collecting line 68, which is connected via a current measuring device 69 to a return line to the energy source 66 connected is. In addition, the computer 61 is connected to a bus system or a central cable via a conversion module. the function of the central control unit 11 will now be explained in more detail with reference to the diagrams in FIGS. 8 and 9.

Grundsätzlich erfolgt die Kontrolle des Fachzustandes, ob das Schloß 16 geschlossen oder geöffnet ist oder eine Störung im elektrischen System vorliegt, anhand des Stromanstieges, nachdem der Schalter 67 geschlossen wurde und der einem bestimmten Schloß 16 zugeordnete Antrieb 26 an die Strommeßvorrichtung 69 angelegt ist.Basically, the technical condition is checked whether the lock 16 is closed or open or whether there is a fault in the electrical system based on the current increase after the switch 67 has been closed and the drive 26 assigned to a specific lock 16 has been applied to the current measuring device 69.

In Fig.8 ist nun auf der Abszisse 70 die Zeit in Mikrosekunden und auf der Ordinate 71 der Strom in mA aufgetragen.In FIG. 8, the time in microseconds is now plotted on the abscissa 70 and the current in mA on the ordinate 71.

In der Zentralsteuereinheit 11 bzw. dem Rechner 61 sind nunmehr zwei Schaltschwellen 72,73 - durch strichlierte Linien angedeutet - vorgegeben. Wird nun eine leitende Verbindung zwischen der Energiequelle 66 und einem der Antriebe 26 der Schließfächer 2 durch Schließen eines Schalters 67 hergestellt, so wird der Antrieb 26 über die Strommeßvorrichtung 69 an eine zur Energiequelle 66 rückführende Leitung angeschlossen.In the central control unit 11 or the computer 61, two switching thresholds 72, 73 - indicated by dashed lines - are now specified. If a conductive connection is now established between the energy source 66 and one of the drives 26 of the lockers 2 by closing a switch 67, the drive 26 is connected via the current measuring device 69 to a line leading back to the energy source 66.

Mit dem Durchschalten mittels des Schalters 67 wird gleichzeitig eine Zeitmeßvorrichtung aktiviert, die mit de Zeitmessung bzw. der Zählung von Clockimpulsen beginnt. Mit dem Durchschalten mittels des Schalters 67 steigt aufgrund der durch die spule 39 gebildeten Induktivität der Strom nach einer e-Funktion an. Überschreitet die Stromstärke eine der beiden Schaltschwellen 72 bzw. 73, so wird der Meßvorgang der Zeitmeßvorrichtung beendet. Gleichzeitig wird beim Erreichen der durch die Schaltschwellen 72 bzw. 73 definieren Stromstärke der Schalter 67 wieder geöffnet und die Stromzufuhr zur Spule 39 unterbrochen.With the switching by means of the switch 67, a time measuring device is simultaneously activated, which begins with the time measurement or the counting of clock pulses. With the switching by means of the switch 67, the current increases according to an e-function due to the inductance formed by the coil 39. If the current exceeds one of the two switching thresholds 72 or 73, the measuring process of the time measuring device is ended. At the same time, when the current strength defined by the switching thresholds 72 and 73 is reached, the switch 67 is opened again and the current supply to the coil 39 is interrupted.

Die ermittelte Zeitdauer ist nunmehr eine dem Betriebszustand des Schließfaches 2 definierende Größe und gleichzeitig ein Maß für die Induktivität. Ist die Induktivität beispielsweise doppelt so hoch, so wird beispielsweise die doppelte Zeit benötigt, um die Schaltschwelle 72 zu erreichen. Desweiteren werden in einem der Speicher 62 bzw. 63 verschiedene Zeitbereich 74,75,76 definiert. Fällt die ermittelte Zeit beispielsweise in den Zeitbereich 74, d.h. die Schaltschwelle 72 wird über eine Zeit bis zu 850 Mikrosekunden erreicht, so bedeutet dies, daß das Magnetfelds nicht geschlossen ist - die stirnseiten 43 der beiden Schenkel des Eisenkemes 40 sind nicht über den Sperriegel 27, wie beispielsweise in Fig.6 gezeigt, verbunden - wodurch eine niedere Induktivität vorliegt, sodaß der Strom ca. 850 Mikrosekunden bis zum Erreichen der Schaltschwelle 72 benötigt. Dies bedeutet andererseits, daß das Fach offen ist, da sich der Sperriegel 27 nicht im Bereich des Antriebes 26 bzw. des Eisenkemes 40 befindet.The time period determined is now a variable defining the operating state of the locker 2 and at the same time a measure of the inductance. If the inductance is twice as high, for example, twice the time is required to reach the switching threshold 72. Furthermore, different time ranges 74, 75, 76 are defined in one of the memories 62 and 63, respectively. If the determined time falls, for example, in the time range 74, ie the switching threshold 72 is reached over a period of up to 850 microseconds, this means that Magnetic field is not closed - the end faces 43 of the two legs of the iron core 40 are not connected via the locking bolt 27, as shown for example in FIG. 6 - as a result of which there is a low inductance, so that the current is approximately 850 microseconds until the switching threshold 72 is reached needed. On the other hand, this means that the compartment is open since the locking bolt 27 is not in the area of the drive 26 or the iron core 40.

Fällt dagegen die ermittelte Zeit in den Zeitbereich 75 zwischen beispielsweise 850 bis 3.000 Mikrosekunden, ist die Induktivität sehr hoch, da das Magnetfeld durch den Sperriegel 27 geschlossen ist, wodurch eine längere Zeit benötigt wird, bis die Stromstärke die Schaltschwelle 72 erreicht hat. Bedingt durch mechanische Toleranzen und einen sich ändernden Luftspalt zwischen den Stirnseiten 43 des Eisenkemes 40 und dem Sperriegel 27 schwankt in diesem Fall die ermittelte Zeit zwischen beispielsweise 850 bis 3.000 Mikrosekunden.If, on the other hand, the determined time falls in the time range 75 between, for example, 850 to 3,000 microseconds, the inductance is very high since the magnetic field is closed by the locking bar 27, which means that a longer time is required until the current intensity has reached the switching threshold 72. Due to mechanical tolerances and a changing air gap between the end faces 43 of the iron core 40 and the locking bolt 27, the determined time in this case fluctuates between, for example, 850 to 3,000 microseconds.

Liegt die ermittelte Zeit daher im Zeitbereich 75, ist davon auszugehen, daß das Fach geschlossen und verriegelt ist.If the determined time is therefore in the time range 75, it can be assumed that the compartment is closed and locked.

Liegt die ermittelte Zeit dagegen in dem Zeitbereich 76, also oberhalb einer Zeitdauer von 3.000 Mikrosekunden, so kann auf eine Störung, beispielsweise einen Kabelbruch, geschlossen werden. In diesem Fall setzt der Rechner 61 eine Störungsmeldung an die Zentralsteuereinheit 11 bzw. die Überwachungsvorrichtung 65 oder eine an diese angeschlossene Melde- und Überwachungsvorrichtung 77 ab.If, on the other hand, the determined time is in the time range 76, that is to say above a time period of 3,000 microseconds, a fault, for example a cable break, can be concluded. In this case, the computer 61 issues a malfunction report to the central control unit 11 or the monitoring device 65 or a reporting and monitoring device 77 connected to it.

Wird dagegen beispielsweise die Schaltschwelle 73 bereits im Zeitbereich 74 überschritten, d.h. der Strom steigt sehr rasch an, kann darauf geschlossen werden, daß ein Kurzschluß vorliegt. In diesem Fall meldet der Rechner 61 an die Zentralsteuereinheit 11 bzw. an die Überwachungsvorrichtung 65 diesen Kurzschluß und schaltet das System bzw. zumindest das defekte Schließfach 2 sicherheitshalber ab, um Beschädigungen der eingebauten Anlageteile zu verhindem.If, on the other hand, the switching threshold 73 is already exceeded in the time range 74, i.e. the current rises very quickly, it can be concluded that there is a short circuit. In this case, the computer 61 reports this short circuit to the central control unit 11 or to the monitoring device 65 and switches off the system or at least the defective locker 2 for safety reasons in order to prevent damage to the installed system parts.

Diese Verfahrensweise zur Überwachung der einzelnen Schließfächer 2 hat weiters den Vorteil, daß durch die kurze Einschaltdauer des Stromes und die an die Meßwertermittlung sofort erfolgende Abschaltung die Spule 39 nur eine sehr geringe Kraft auf den Sperriegel 27 ausübt. Diese ist zwar vorteilhaft, um den Sperriegel 27 zu den stirnseiten 43 des Eisenkernes 40 herzuziehen und den Luftspalt so gering wie möglich zu halten. Sie reicht aber nicht aus, um den Sperriegel 27 in seiner Position gegenüber dem Profil 18 zu halten, für den Fall, daß in den wenigen Sekundenbruchteilen, in welchen die Überprüfung des Schaltzustandes des Schließfaches 2 erfolgt, das Schloß 16 mit dem Schlüssel 22 gesperrt werden kann und ein Öffnen bzw. ein Zurückziehen des Hauptriegels 24 möglich ist. Neben der hohen Sicherheit wird dadurch aber auch mit einem geringen Energieaufwand das Auslangen gefunden, wodurch auch unerwünschte Erwärmungen im Bereich der Spulen 39 bzw. Eisenkerne 40 vermieden werden.This procedure for monitoring the individual lockers 2 has the further advantage that the coil 39 exerts only a very small force on the locking bolt 27 due to the short on-time of the current and the instantaneous switch-off of the measured value determination. Although this is advantageous to the locking bolt 27 to the ends 43 of the iron core 40 and to keep the air gap as small as possible. However, it is not sufficient to hold the locking bolt 27 in its position in relation to the profile 18, in the event that the lock 16 is locked with the key 22 in the fraction of a second in which the switching state of the locker 2 is checked can and an opening or retraction of the main bolt 24 is possible. In addition to the high level of security, this also makes it possible to find sufficient length with a low expenditure of energy, as a result of which undesirable heating in the area of the coils 39 or iron cores 40 is also avoided.

Um auch bei großen mechanischen Toleranzen den Sperriegel 27 gut an den Stirnseiten 43 der Schenkel des Eisenkernes 40 anliegen zu lassen, ist es auch möglich, einen ständigen Gleichstrom von ca. 8 mA durch jede Spule 39 fließen zu lassen. Dies führt weder zu einem Festhalten des Sperriegels 27, noch stört es die Abfrage, ob das Fach offen oder geschlossen ist. Es wird aber deutlich der Unterschied zwischen den den offenen bzw. geschlossenen Zustand des Schließfaches 2 festlegenden Zeitbereich geschaffen.In order to allow the locking bolt 27 to rest well against the end faces 43 of the legs of the iron core 40 even with large mechanical tolerances, it is also possible to have a constant direct current of approximately 8 mA flow through each coil 39. This does not result in the locking bolt 27 being held in place, nor does it interfere with the query as to whether the compartment is open or closed. However, the difference between the time range defining the open or closed state of the locker 2 is clearly created.

In Fig.8 ist diese Art der Abfrage bei der in vollen Linien gezeichneten Kennlinie 78 gezeigt. Die Stromstärke steigt, wie ein Kurventeil 79 zeigt, von beispielsweise 8 mA auf eine vorher festgelegte Schaltschwelle 72 innerhalb von 800 Mikrosekunden an. Bei Erreichen des Schaltschwelle 72 wird der Strom gemäß dem Kurventeil 80 auf 8 mA abgesenkt, wie dies der Kurventeil 81 zeigt. Nach dem Ablauf von 4 ms wird der Strom wieder eingeschaltet und steigt gemäß dem Kurventeil 79 wieder an, bis er die Schaltschwelle 72 wieder erreicht hat. Stimmen nun die beiden ermittelten Zeiten von zwei im Abstand von 4 ms durchgeführten Abfragen überein, so wird diese Ergebnis vom Rechner 61 als richtiges Ergebnis anerkannt und in einem der Speicher 62 bzw. 63 der Zentralsteuereinheit 11 abgelegt. Erbringt die zweite Abfrage nach 4 ms ein anderes Ergebnis, so wird das Ergebnis als Störung anerkannt und verworfen. Nach weiteren 4 ms einer ordnungsgemäß durchgeführten Abfrage wird das nächste Schließfach 2 auf seinen Zustand abgefragt.This type of query is shown in FIG. 8 with the characteristic curve 78 drawn in full lines. The current strength increases, as a curve part 79 shows, from, for example, 8 mA to a predetermined switching threshold 72 within 800 microseconds. When the switching threshold 72 is reached, the current is reduced to 8 mA according to the curve part 80, as the curve part 81 shows. After a period of 4 ms, the current is switched on again and rises again according to the curve part 79 until it has reached the switching threshold 72 again. If the two determined times of two queries carried out at 4 ms intervals now match, this result is recognized by the computer 61 as the correct result and is stored in one of the memories 62 and 63 of the central control unit 11. If the second query produces a different result after 4 ms, the result is recognized as a fault and rejected. After another 4 ms of a properly executed query, the next locker 2 is queried for its status.

In den Speichern 62,63 der Zentralsteuereinheit bzw. den entsprechenden Speichern des Rechners 61 wird immer der zuletzt ermittelte Zustand des Faches abgelegt, so daß zu jedem beliebigen Zeitpunkt der aktuelle Stand jedes beliebigen Schließfaches 2 abgefragt werden kann. Da das verwendete Betriebssystem multitaskingfähig ist, kann während der laufenden Abfragen zur Schließfächer 2 beispielsweise von der Zentralsteuereinheit 11 abgefragt und auf der Überwachungsvorrichtung 65 bzw. der Melde- und Überwachungsvorrichtung 77, beispielsweise einem Bildschirm, graphisch angezeigt werden.The last determined state of the subject is always stored in the memories 62, 63 of the central control unit or the corresponding memories of the computer 61, so that the current status of any one is at any time Locker 2 can be queried. Since the operating system used is multitasking capable, it can be queried, for example, by the central control unit 11 during the current queries for the lockers 2 and displayed graphically on the monitoring device 65 or the reporting and monitoring device 77, for example a screen.

Kommt es bei diesen Abfragen zu entsprechenden Unregelmäßigkeiten bzw. wird vom Rechner 61 festgestellt, daß ein nicht zur Öffnung freigegebenes Schließfach 2 geöffnet ist, kann über die vorher angegebenen Überwachungsvorrichtungen 65 bzw. die Melde- und Überwachungsvorrichtung 77 ein Alarmsignal abgeben bzw. eine selbständige Alarmierung von Kontrolleinheiten bzw. Polizeikräften erfolgen.If there are corresponding irregularities in these queries or if the computer 61 determines that a locker 2 that has not been opened for opening is open, an alarm signal or an independent alarm can be emitted via the previously specified monitoring devices 65 or the reporting and monitoring device 77 carried out by control units or police forces.

Anhand des Diagrammes in Fig.9, bei welchem auf der Abszisse 82 die Zeit in ms und auf der Ordinate 83 wiederum der Strom in mA aufgetragen ist, ist der Schaltvorgang zum Freigeben eines Schließfaches 2 bzw. der Stromverlauf in einer die Freigabe des Schlosses 26 bewirkenden Leitung dargestellt.9, in which the time in ms is plotted on the abscissa 82 and the current in mA is again plotted on the ordinate 83, the switching process for releasing a locker 2 or the current curve in a release of the lock 26 effecting line shown.

Soll nun ein Schließfach 2 zum Öffnen freigegeben werden, so wird die Spule 39 nicht nur kurz, wie anhand des Diagrammes in Fig.8 gezeigt, eingeschaltet, sondem über eine längere Zeitdauer mit Strom versorgt. Dadurch erzeugt die Spule 39 ein so starkes Magnetfeld im Eisenkern 40, daß der Sperriegel 27 mit einer ausreichenden Haltekraft gegen die Verschiebewirkung des Hauptriegels 24 zurückgehalten werden kann. Damit kann, wie anhand der vorstehend beschriebenen Figuren im Detail erläutert, der Hauptriegel 24 zur Gänze in das Schloßgehäuse 32 zurückgezogen werden und das Türelement 14 kann geöffnet werden.If a locker 2 is now to be released for opening, the coil 39 is not only switched on briefly, as shown in the diagram in FIG. 8, but is also supplied with power over a longer period of time. As a result, the coil 39 generates such a strong magnetic field in the iron core 40 that the locking bolt 27 can be retained with sufficient holding force against the displacement effect of the main bolt 24. Thus, as explained in detail with reference to the figures described above, the main bolt 24 can be withdrawn entirely into the lock housing 32 and the door element 14 can be opened.

Um nun auch während der Zeit, während der ein Schließfach 2 zum Öffnen freigegeben ist, eine Überwachung der anderen Schließfächer 2 durchführen zu können und gleichzeitig bei dem geöffneten Schließfach 2 den Fachzustand, nämlich "offen" erkennen zu können, wird als 15 ms die Stromzufuhr zur Spule 39 kurz abgeschaltet. Während dieser Zeit wird die Stromzufuhr zur Spule 39 des zu überprüfenden Schließfaches eingeschaltet und, wie vorstehend anhand des Diagrammes in Fig.8 beschrieben, gemessen. Dann wird die Stromzufuhr zum angemeldeten Schließfach 2 sofort wieder hergestellt.In order to be able to monitor the other lockers 2 even while a locker 2 is open for opening and at the same time to be able to recognize the specialist state, namely "open", when the locker 2 is open, the power supply becomes 15 ms switched off to the coil 39 briefly. During this time, the power supply to the coil 39 of the locker to be checked is switched on and, as described above with the aid of the diagram in FIG. 8, measured. Then the power supply to the registered locker 2 is immediately restored.

Im einzelnen ergibt sich anhand der Darstellung in Fig.9 nunmehr, daß beispielsweise der Strom zum Zeitpunkt t = 0 eingeschaltet und auf einen Wert oberhalb der Schaltschwelle 72 angehoben wird. Diese Strombeaufschlagung wird über eine Zeitspanne von z.B. 10 bis 25 ms, bevorzugt 15 ms, aufrecht erhalten, wie dies anhand der Kennlinie 84 gezeigt ist.9 shows that, for example, the current is switched on at time t = 0 and raised to a value above switching threshold 72. This current is applied over a period of e.g. 10 to 25 ms, preferably 15 ms, are maintained, as shown by the characteristic curve 84.

Danach wird über einen Schalter 67 ein anderes Schließfach 2 für eine Zeitspanne von etwa 2 bis 10 ms, bevorzugt 5 ms, eingeschaltet. Dabei zeigt die Kennlinie 85 den Stromanstieg und -abfall für ein Schließfach 2, welches geschlossen ist. Diese Kennlinie 85 ist nur schematisch dargestellt, denn, wie aus den Erläuterungen zu Fig.8 zu entnehmen ist, kann in dieser Zeit auch eine Doppelabfrage erfolgen, wobei dann das Intervall zwischen zwei aufeinanderfolgenden Abfragen beispielsweise nur 2 bis 3 ms betragen kann. In diesem Fall würde die Kennlinie 85 die in strichlierten Linien eingezeichnete Form einnehmen. Nach Ablauf von 2 bis 7 ms wird dann wieder die Spule 39 jenes Schließfaches mit Strom beaufschlagt, welches zur Öffnung freigegeben ist. Damit entsteht wieder ein Stromverlauf gemäß der Kennlinie 84.Another locker 2 is then switched on via a switch 67 for a period of approximately 2 to 10 ms, preferably 5 ms. The characteristic curve 85 shows the current rise and fall for a locker 2 which is closed. This characteristic curve 85 is only shown schematically, because, as can be seen from the explanations for FIG. 8, a double interrogation can also take place during this time, in which case the interval between two consecutive interrogations can be, for example, only 2 to 3 ms. In this case, the characteristic curve 85 would take the form drawn in dashed lines. After 2 to 7 ms have elapsed, the coil 39 of that locker which is released for opening is again supplied with current. This again creates a current profile according to characteristic curve 84.

Nach Ablauf einer weiteren Zeitperiode von 15 ms erfolgt dann die Abfrage beispielsweise eines weiteren Schließfaches, wodurch wieder die symbolisch dargestellte Kennlinie 85 entsteht. Unmittelbar darauf wird wieder die Spule 39 des zur Öffnung vorgesehenen Schließfaches 2 gemäß Kennlinie 84 mit Strom beaufschlagt.After a further period of 15 ms has elapsed, for example, another locker is queried, which again results in the symbolically represented characteristic curve 85. Immediately afterwards, the coil 39 of the locker 2 provided for opening is again supplied with current according to characteristic curve 84.

In der nächsten Zwischenperiode, in der die Strombeaufschlagung der Spule 39 unterbrochen wird, wird beispielsweise nun, wie anhand der Kennlinie 86 ersichtlich, ein Schließfach abgefragt, welches offen ist, wodurch die Zeitdauer bis zum Anstieg des Stromwertes auf die Schaltschwelle 72, wie schematisch gezeigt, geringer ist als bei den Kennlinien 85. Wird die Zentralsteuereinheit 11 bzw. der Rechner 61 so ausgelegt, daß er einen Abfragerhythmus durchführt, wie er anhand des Diagramms in Fig.8 beschrieben worden ist, so würde auch in dieser Darstellung die Kennlinie 86 die in strichlierten Linien angedeutete Form einnehmen, also zwei erheblich schmälere Spitzen liefern, als beispielsweise bei der Kennlinie 85, da bei einem offenen Schließfach 2 der Strom auf den Schwellwert 72 in einer Zeit von unter 800 Mikrosekunden ansteigt.In the next intermediate period, in which the current supply to the coil 39 is interrupted, for example, as can be seen from the characteristic curve 86, a locker is now queried which is open, as a result of which the time until the current value rises to the switching threshold 72, as shown schematically , is lower than for the characteristic curves 85. If the central control unit 11 or the computer 61 is designed in such a way that it carries out an interrogation rhythm as was described with the aid of the diagram in FIG. 8, the characteristic curve 86 would also be in this representation Take the form indicated by dashed lines, that is to say deliver two significantly narrower peaks than, for example, characteristic curve 85, since with an open locker 2 the current rises to the threshold value 72 in a time of less than 800 microseconds.

Zusammenfassend ist festzuhalten, daß durch die zwischen den Kennlinien 84 liegenden Unterbrechungen der Stromzufuhr zu den Spulen 39 die Möglichkeit das zur Öffnung angemeldete Schließfach 2 zu öffnen, nicht gestört wird. Diese Unterbrechungen wirken sich so aus, als wenn die Spule 39 nicht an die volle, sondern nur an eine verringerte Betriebsspannung angelegt worden wäre. Durch eine entsprechend hohe Wahl der Betriebsspannung läßt sich daher dies Abschwächung der Leistung der Spule 39 ausgleichen.In summary, it should be noted that the interruptions in the power supply to the coils 39 lying between the characteristic curves 84 do not interfere with the possibility of opening the locker 2 registered for opening. These interruptions have the effect as if the coil 39 had not been applied to the full, but only to a reduced operating voltage. This weakening of the power of the coil 39 can therefore be compensated for by a correspondingly high selection of the operating voltage.

Um bei dieser Betriebsart zu verhindern, daß der Sperriegel 27 am Eisenkern 40 infolge Remanenz kleben bleibt, ist der Eisenkern 40 aus mehreren Dynamoblechen 41 mit geringer Remanenz, und nicht aus Weicheisen gefertigt. Bei entsprechender Auslegung der elektrischen Teile ist es jedoch ebenso auch möglich, Weicheisenkerne zu verwenden.

In order to prevent the locking bar 27 from sticking to the iron core 40 as a result of remanence in this operating mode, the iron core 40 is made from several dynamo sheets 41 with low remanence, and not from soft iron. With appropriate design of the electrical parts, it is also possible to use soft iron cores.
