Description

Die Erfindung betrifft einen Verkaufsautomaten, insbesondere Parkscheinautomaten, mit einem Innenaufbau, in welchem eine Kasse zur Aufnahme von Münz- und/oder Papiergeld angeordnet ist, einem den Innenaufbau umschließenden Gehäuse und einem Schließsystem zum Schutz der Kasse vor unbefugtem Zugriff.The invention relates to a vending machine, in particular parking ticket machines, with an internal structure in which a cash register for receiving coin and / or paper money is arranged, a housing enclosing the interior structure and a locking system to protect the cash register from unauthorized access.

Beim Betrieb derartiger Verkaufsautomaten sammelt sich in der Kasse ein bis zum nächsten Leerungsgang steigender Betrag an Bargeld an, der vor Diebstahl zu schützen ist. Dies trifft gleichermaßen für Parkscheinautomaten, aber auch für Fahrkarten-, Zigaretten- sowie Warenautomaten zu, bei welchen beträchtliche Anstrengungen zum Schutz des Verkaufsautomaten gegen Vandalismus, Einbruch bzw. Diebstahl der Kasse, unternommen werden.In the operation of such vending machines accumulates in the cash until the next emptying gear increasing amount of cash to protect against theft. This applies equally to parking ticket machines, but also to ticket, cigarette and vending machines, in which considerable efforts are made to protect the vending machine against vandalism, burglary or theft of the cash register.

Aus der DE-Druckschrift "SITRAFFIC SITY 5 Der neue Parkscheinautomat" Ausgabe 003, Bestell-Nr. E10003-A800-W19, herausgegeben von Siemens AG am 02.05.2002, ist es bekannt, ein nahezu fugenfrei verarbeitetes, glattflächiges Gehäuse aus einem umlaufenden Edelstahlmantel vorzusehen, um keine Angriffsfläche für Zerstörungswut zu bieten. Dennoch enthalten derartige Verkaufsautomaten Türen, Klappen oder Schubladen für eine Kassenentnahme zum Entleeren oder Austauschen gegen eine leere Kasse. Derart sensible Teile sind mit Zylinderschlössern abgeriegelt, wobei eine Doppelschließung durch mechanische und/oder elektromechanische Schließsysteme bekannt ist.From the DE publication "SITRAFFIC SITY 5 The new parking ticket machine" Edition 003, order no. E10003-A800-W19, published by Siemens AG on 02.05.2002, it is known to provide a virtually joint-free processed, smooth-surfaced housing made of a surrounding stainless steel jacket, in order to provide no attack surface for destructiveness. Nevertheless, such vending machines contain doors, flaps or drawers for a cash withdrawal for emptying or exchange for an empty cash register. Such sensitive parts are sealed off with cylinder locks, wherein a double closure by mechanical and / or electromechanical locking systems is known.

Aus der Patentschrift DE 101 04 122 C2 ist beispielsweise ein Gehäuse mit einer Tür oder Klappe zum Verschließen einer Gehäuseöffnung bekannt, die einen Verriegelungsmechanismus mit mindestens einer in ihrer Längsrichtung verschiebbaren Verrieglungsstange und einem mit dieser in Wirkverbindung stehenden Schloss aufweist. Dabei ist quer zur Verschieberichtung der Verriegelungsstange jeweils eine ihr zugeordnete und von ihr in Verschieberichtung auslenkbare Verriegelungsleiste angeordnet, die im verriegelten Zustand einen an die Gehäuseöffnung grenzenden Behälterrand oder mindestens einen Verriegelungsvorsprung hintergreift.From the patent DE 101 04 122 C2, for example, a housing with a door or flap for closing a housing opening is known, which has a locking mechanism with at least one displaceable in its longitudinal direction Verrieglungsstange and one with this in operative connection Castle has. In this case, a respective associated and deflectable in the direction of displacement locking bar is arranged transversely to the direction of displacement of the locking bar, which engages in the locked state adjacent to the housing opening container edge or at least one locking projection.

Ferner offenbart die Gebrauchsmusterschrift DE 201 17 800 U1 einen Verschluss für Türen oder Schubladen von Schränken, Verkaufsautomaten oder dergleichen mit einem Riegelelement und einem Schlüssel. Der Schlüssel weist einen Transponder auf, welcher nach Empfang eines von einer Antenne des Verschlusses abgegebenen Anregungssignals an die Antenne eine Kennung zurückgibt, die von einer elektronischen Steuereinrichtung des Verschlusses auf eine Schließberechtigung des Schlüssels überprüfbar ist. Das Riegelelement weist einen verzahnten Abschnitt auf, in dessen Zähne die Zähne eines von einem Antriebsmotor antreibbaren Zahnrades eingreifen, wobei der Antriebsmotor von der elektronischen Steuerung zur Drehung in beiden Drehrichtungen ansteuerbar ist.Furthermore, the utility model DE 201 17 800 U1 discloses a closure for doors or drawers of cabinets, vending machines or the like with a locking element and a key. The key has a transponder which, after receiving an excitation signal emitted by an antenna of the shutter, returns to the antenna an identifier which can be checked by an electronic control device of the shutter for a locking authorization of the key. The locking element has a toothed portion, in the teeth of which engage the teeth of a driven by a drive motor gear, wherein the drive motor is controlled by the electronic control for rotation in both directions of rotation.

Nachteilig an den bekannten Verkaufsautomaten sind Türen, Klappen, Schubladen und der gleichen Öffnungen im Gehäuse, durch die Zugriff auf die Kasse genommen wird, die aber trotz Schließsystemen stets Ansatzpunkte für Aufbruchversuche zum unbefugten Zugriff auf die Kasse darstellen. Ein weiterer Nachteil bekannter elektronischer Automatenverschlüsse ist das Erfordernis einer internen Energieversorgung für das Schließsystem, bei deren Ausfall eine aufwendige Notöffnung des Verkaufsautomaten erfolgen muss und außerdem ein Risiko für einen gewaltsamen Eingriff herrscht.A disadvantage of the known vending machines are doors, flaps, drawers and the same openings in the housing, is taken by the access to the cash register, but despite locking systems are always starting points for attempts to break up for unauthorized access to the cashier. Another disadvantage of known electronic vending machine closures is the requirement of an internal power supply for the locking system, in the absence of which a complex emergency opening of the vending machine must be made and also there is a risk of a violent intervention.

Der Erfindung liegt daher die Aufgabe zugrunde, einen Verkaufsautomaten der eingangs genannten Art bereitzustellen, der sicherer gegen einen unbefugten Zugriff auf die Kasse ist.The invention is therefore based on the object to provide a vending machine of the type mentioned, which is safer against unauthorized access to the cash register.

Die Aufgabe wird erfindungsgemäß gelöst durch einen gattungsgemäßen Verkaufsautomaten, bei dem das Gehäuse im Wesentlichen geschlossen ausgebildet ist und bei dem das Schließsystem ein tragbares Handgerät mit einer Sendeeinheit und eine im Gehäuse angeordnete Verriegelungseinrichtung mit Empfangseinheit aufweist, wobei das Schließsystem durch Wechselwirkung der Sendeeinheit mit der Empfangseinheit betätigbar ist. Zum einen ist also das Gehäuse als nach unten offene Haube ohne eine Entnahmeöffnung für die Kasse ausgebildet, die lediglich Schlitze für den Geldeinwurf oder eine Karteneinführung sowie eine Ausgabeöffnung für Parkscheine oder Wechselgeld und Ausnehmungen für eine Tastatur und ein Anzeigelement aufweist. Indem Türen, Klappen oder Schubladen, die Angriffspunkte für gewaltsames Öffnen des Gehäuses bilden, vermieden werden, wird die Sicherheit eines erfindungsgemäßen Verkaufsautomaten erheblich erhöht. Zur befugten Entnahme der Kasse könnte das Gehäuse beispielsweise vertikal verfahrbar oder ganz vom Innenaufbau abnehmbar ausgebildet sein. Zum anderen beruht das Schließsystem auf einer Wechselwirkung zwischen einer in einem tragbaren Handgerät befindlichen, aktiven Sendeeinheit und einer im Gehäuse angeordneten Empfangseinheit, die passiv ist und damit zunächst einmal keine eigene Energieversorgung benötigt.The object is achieved by a generic vending machine, wherein the housing is formed substantially closed and in which the locking system comprises a portable handset with a transmitting unit and a housing arranged in the locking device with receiving unit, wherein the locking system by interaction of the transmitting unit with the receiving unit is operable. On the one hand, therefore, the housing is designed as a downwardly open hood without a discharge opening for the cash register, which has only slots for the money or a card insertion and a discharge opening for parking tickets or change and recesses for a keyboard and a display element. By avoiding doors, flaps or drawers, which are points of attack for forced opening of the housing, the security of a vending machine according to the invention is considerably increased. For authorized removal of the cash register, the housing could for example be designed to be vertically movable or completely removable from the inner structure. On the other hand, the locking system is based on an interaction between an active transmitting unit located in a portable handheld device and a receiving unit arranged in the housing, which is passive and thus initially does not need its own power supply.

In einer bevorzugten Ausgestaltung des erfindungsgemäßen Verkaufsautomaten sind Sende- und Empfangseinheit zur Wechselwirkung nur über eine kurze Übertragungsreichweite ausgebildet. Damit die Sendeeinheit mit der Empfangseinheit in Wechselwirkung treten kann, muss das Handgerät direkt an das Gehäuse und an die richtige Stelle des Gehäuses gehalten werden. Durch die kurzreichweitige Übertragung, die vorzugsweise im Bereich weniger Zentimeter liegt, ist die Übertragung vom Handgerät sicher gegen unerlaubtes Abhören.In a preferred embodiment of the vending machine according to the invention, the transmitting and receiving units are designed to interact only over a short transmission range. In order for the transmitting unit to interact with the receiving unit, the handset must be held directly to the housing and to the correct location of the housing. Due to the short-range transmission, which is preferably in the range of a few centimeters, the transmission from the handset is secure against unauthorized listening.

In einer vorteilhaften Ausführungsform des erfindungsgemäßen Verkaufsautomaten weisen Sende- und Empfangseinheit je eine Spule auf, die zur Wechselwirkung induktiv koppelbar sind.In an advantageous embodiment of the vending machine according to the invention, the transmitting and receiving units each have a coil, which can be inductively coupled for interaction.

Die im Wechselwirkungsbereich aneinander gehaltenen Spulen bilden einen Lufttransformator mit primärseitiger Sendeeinheit und sekundärseitiger Empfangseinheit, die durch die Wand des Gehäuses voneinander getrennt sind. Die induktive Kopplung erlaubt die Übertragung einer elektrischen Spannung von der Sende- zur Empfangseinheit. Bei richtiger Positionierung des Handgerätes relativ zum Verkaufsautomaten können Sende- und Empfangseinheit berührungslos miteinander in Wechselwirkung treten, um ohne Gehäuseöffnung das Schließsystem zu betätigen.The coils held together in the interaction region form an air transformer with a primary-side transmission unit and a secondary-side reception unit, which are separated from one another by the wall of the housing. The inductive coupling allows the transmission of an electrical voltage from the transmitting to the receiving unit. With proper positioning of the handset relative to the vending machine transmitting and receiving unit contact interact with each other without contact, to operate without closing the housing closure system.

In einer bevorzugten Ausführungsform des erfindungsgemäßen Verkaufsautomaten weist die Sendeeinheit eine Spannungsquelle und Mittel zum Erzeugen einer Wechselspannung sowie zum Aufprägen eines Signals mit Schlüsselkodierung für das Schließsystem auf, wobei die Wechselspannung mit dem aufgeprägten kodierten Signal zum Übertragen an die Empfangseinheit vorgesehen sind. Die Spannungsquelle kann durch eine 9 V Batterie oder einen entsprechenden wiederaufladbaren Akkumulator gebildet sein, die einen Mikroprozessor versorgt. Mittels des Mikroprozessors wird eine Wechselspannung mit vorgebbarer Frequenz erzeugt, die an der primärseitigen Sendespule der Sendeinheit anliegt. Des Weiteren kann der Wechselspannung mittels des Mikroprozessors ein Signal aufgeprägt werden, welches eine Schlüsselkodierung für das Schließsystem enthält. Dies stellt gewissermaßen den "Schlüssel" für das erfindungsgemäße Schließsystem dar.In a preferred embodiment of the vending machine according to the invention, the transmitting unit has a voltage source and means for generating an alternating voltage and impressing a signal with key coding for the locking system, wherein the alternating voltage are provided with the impressed coded signal for transmission to the receiving unit. The voltage source may be formed by a 9V battery or a corresponding rechargeable accumulator that powers a microprocessor. By means of the microprocessor, an alternating voltage with a predeterminable frequency is generated, which is applied to the primary-side transmitting coil of the transmitting unit. Furthermore, the AC voltage can be impressed by means of the microprocessor, a signal containing a key coding for the locking system. In a sense, this represents the "key" for the locking system according to the invention.

Vorzugsweise sind die als Mikroprozessor ausgebildeten Spannungserzeugungs- und Aufprägungsmittel derart ausgebildet, dass die Frequenz der Wechselspannung und die Schlüsselkodierung des aufgeprägten Signals variierbar sind. Damit stehen zwei Parameter zur Verfügung, um den Schlüssel für das Schließsystem von Zeit zu Zeit zu verändern und damit die Sicherheit des erfindungsgemäßen Verkaufsautomaten wesentlich zu erhöhen.Preferably, the voltage generating and embossing means designed as a microprocessor are designed such that the frequency of the AC voltage and the key coding of the impressed signal can be varied. Thus, two parameters are available to change the key for the locking system from time to time and thus significantly increase the security of the vending machine according to the invention.

In einer vorteilhaften Ausgestaltung des erfindungsgemäßen Verkaufsautomaten weist die Empfangseinheit Mittel zum Filtern eines der übertragenen Wechselspannung aufgeprägten Signals und Mittel zum Auswerten des ausgefilterten Signals hinsichtlich der Gültigkeit der übertragenen Schlüsselkodierung auf. Eine übertragene Schlüsselkodierung ist gültig, wenn beispielsweise von den ebenfalls als Mikroprozessor ausgebildeten Auswertungsmitteln festgestellt wird, dass sie mit einer in der Empfangseinheit hinterlegten Schlüsselkodierung übereinstimmt. Eine vorliegende Gültigkeit der Schlüsselkodierung löst eine Schließberechtigung für das Schließsystem aus, also zum Aufschließen oder zum Verschließen mittels der Verriegelungseinrichtung. Bei diesem Vorgang wird gewissermaßen probiert, ob der "Schlüssel" in das "Schloss" passt.In an advantageous embodiment of the vending machine according to the invention, the receiving unit has means for filtering a signal impressed on the transmitted alternating voltage and means for evaluating the filtered-out signal with regard to the validity of the transmitted key coding. A transmitted key coding is valid if, for example, the evaluation means, which are also designed as a microprocessor, determine that they match a key code stored in the receiving unit. A present validity of the key code triggers a locking authorization for the locking system, ie for unlocking or locking by means of the locking device. In this process, in a sense, it is tried out whether the "key" fits into the "lock".

In einer weiteren bevorzugten Ausgestaltung des erfindungsgemäßen Verkaufsautomaten weist die Empfangseinheit Mittel zum Speichern von mit der Wechselspannung übertragener Energie auf. Mit Vorteil wird die zum Betätigen der Verriegelungseinrichtung erforderliche Energie von der Sendeeinheit des Handgeräts geliefert, so dass für das Schließsystem automatenseitig keine Energieversorgung erforderlich ist. Wie bereits erwähnt, wird hierdurch eine Notöffnung des Gehäuses vermieden oder das Einbruchsrisiko verhindert, was bei Ausfall einer automatenseitigen Energieversorgung des Schließsystems auftreten kann.In a further preferred embodiment of the vending machine according to the invention, the receiving unit has means for storing energy transmitted with the AC voltage. Advantageously, the energy required to actuate the locking device is supplied by the transmitting unit of the handset, so that no power supply is required for the closing system on the machine side. As already mentioned, this avoids an emergency opening of the housing or prevents the risk of burglary, which can occur in the event of failure of a machine-side power supply of the locking system.

In einer weiteren vorteilhaften Ausführungsform des erfindungsgemäßen Verkaufsautomaten ist die gespeicherte Energie bei vorliegender Gültigkeit der übertragenen Schlüsselkodierung von den Speichermitteln freigebbar. Die gespeicherte Energie kann so lange unverbraucht bleiben, bis eine gültige Schlüsselkodierung übertragen wird. Erst dann wird die Energie für ein Aktivieren des Schließsystems eingesetzt.In a further advantageous embodiment of the vending machine according to the invention, the stored energy can be released from the storage means given the validity of the transmitted key code. The stored energy can remain unused until a valid key encoding is transmitted. Only then will the energy be used to activate the locking system.

In einer ersten Alternative des erfindungsgemäßen Verkaufsautomaten ist die freigegebene Energie einem im Gehäuse angeordneten Stellglied zum Betätigen der Verriegelungseinrichtung zuführbar. Dies kommt zum Einsatz, wenn ein Stellglied - etwa ein Elektromotor - permanent im Gehäuse des Verkaufsautomaten angeordnet ist, das einen Verriegelungseinrichtung mittels der freigegebenen Energie in Öffnungs- oder Verschließrichtung bewegt.In a first alternative of the vending machine according to the invention, the released energy is arranged in the housing Actuator for actuating the locking device fed. This is used when an actuator - such as an electric motor - is permanently arranged in the housing of the vending machine, which moves a locking device by means of the released energy in the opening or closing direction.

In einer zweiten alternativen Ausführungsform des erfindungsgemäßen Verkaufsautomaten ist die freigegebene Energie einem Verschluss einer Schnittstelle für ein externes, mit der Verriegelungseinrichtung koppelbares Stellglied zuführbar. Als externes Stellglied kommt der Motor etwa eines Akkuschraubers in Betracht, der mittels eines Sechskanteinsatzes durch eine verschließbare Öffnung im Gehäuse in eine Innensechskantschraube als Schnittstelle zu einem Linearsystem einsteckbar ist. Die von den Speichermitteln freigegebene Energie öffnet hier lediglich den Verschluss, der als ein die Gehäuseöffnung abdeckendes Blechteil ausgebildet sein kann. Durch Rotation des Sechskanteinsatzes, respektive der Innensechskantschraube, kann das Gehäuse beispielsweise längs vertikalen Führungselementen, die als Schraubenspindeln ausgeführt sind, verfahren werden.In a second alternative embodiment of the vending machine according to the invention, the released energy can be fed to a closure of an interface for an external actuator which can be coupled to the locking device. As an external actuator, the motor comes about as a cordless screwdriver into consideration, which can be inserted by means of a hexagonal insert through a closable opening in the housing in a hexagon socket screw as an interface to a linear system. The energy released by the storage means here only opens the closure, which can be designed as a sheet metal part covering the housing opening. By rotation of the hexagonal insert, respectively the hexagon socket screw, the housing can be moved, for example, along vertical guide elements, which are designed as screw spindles.

In einer weiteren vorteilhaften Ausgestaltung des erfindungsgemäßen Verkaufsautomaten sind die Position der Sendespule innerhalb des Handgerätes und/oder die Position der Empfangsspule innerhalb des Gehäuses von außen jeweils nicht erkennbar. Für den Fall, dass ein Handgerät in unbefugten Besitz gelangt, wird hierdurch eine Wechselwirkung zwischen Sende- und Empfangseinheit erheblich erschwert, da ein möglicher Dieb wissen müsste, welche Stelle des Handgerätes - welches DIN A4-Format haben kann - an welche Stelle des Gehäuses zu halten ist, um den für die Wechselwirkung erforderlichen Lufttransformator zu bilden. Auch dies erhöht die Sicherheit des erfindungsgemäßen Verkaufsautomaten erheblich.In a further advantageous embodiment of the vending machine according to the invention, the position of the transmitting coil within the handset and / or the position of the receiving coil within the housing from the outside are not recognizable. In the event that a handset gets into unauthorized possession, thereby an interaction between transmitting and receiving unit is considerably more difficult, as a potential thief would have to know which position of the handset - which may have DIN A4 format - to which point of the housing is to form the required for the interaction air transformer. This also significantly increases the security of the vending machine according to the invention.

Ein Ausführungsbeispiel sowie weitere Vorteile der Erfindung werden nachfolgend anhand der Zeichnungen näher erläutert, in deren

FIG 1
ein erfindungsgemäßer Verkaufsautomat in geschnittenem Längsschnitt und in
FIG 2
ein Schaltbild der miteinander wechselwirkenden Sende- und Empfangseinheit,
schematisch veranschaulicht sind.An embodiment and further advantages of the invention will be explained in more detail with reference to the drawings, in whose
FIG. 1
an inventive vending machine in a sectional longitudinal section and in
FIG. 2
a circuit diagram of the interacting transmitting and receiving unit,
are illustrated schematically.

Der in FIG 1 in geschnittener Seitenansicht dargestellte Parkscheinautomat 1 ist als Ausführungsbeispiel eines erfindungsgemäßen Verkaufautomaten anzusehen, wobei die Erfindung nicht auf diesen speziellen Automatentyp eingeschränkt ist. Der Parkscheinautomat 1 weist einen Innenaufbau 2 auf, der als massives Gestell mit Rückwand und Fachböden ausgeführt sein kann und nicht dargestellte Komponenten, wie Münzkanal und Münzprüfer, Kartenlese- und Verarbeitungseinheit, Druckeinrichtungen für Parkscheine und Belege, Benutzerschnittstellen wie Eingabetastatur und Anzeigeelemente, sowie ein Energieversorgungsaggregat aufnimmt. Ferner ist im Innenaufbau 2 eine Kasse 3 angeordnet, von der eingeführtes Münz- und/oder Papiergeld aufgenommen wird. Der Innenaufbau 2 ist auf einem Fundamentsockel 4 aus Beton aufgestellt und darin verankert. Der Fundamentsockel 4 ist im Erdboden 5 versenkt, kann aber zum Teil aus dem Erdboden 5 herausragen. Zum Schutz des sensiblen Innenaufbaus 2 vor Wetter und Vandalismus ist dieser von einem Gehäuse 6 umschlossen, welches als nach unten offene aber sonst im Wesentlichen geschlossene Haube ausgebildet ist. Indem das Gehäuse 6 keine Entnahmeöffnung für die Kasse 3 in Form von Türen, Klappen oder Schubladen aufweist, werden Angriffspunkte für ein gewaltsames Öffnen des Gehäuses 6 vermieden und dadurch die Sicherheit des erfindungsgemäßen Parkscheinautomaten 1 erhöht.The parking ticket machine 1 shown in Figure 1 in a sectional side view is to be regarded as an embodiment of a vending machine according to the invention, wherein the invention is not limited to this particular type of vending machine. The parking ticket machine 1 has an internal structure 2, which can be designed as solid frame with rear wall and shelves and components not shown, such as coin channel and coin validator, card reading and processing unit, printing facilities for parking tickets and receipts, user interfaces such as input keyboard and display elements, and a power supply unit receives. Further, a cash register 3 is arranged in the inner structure 2, is taken from the imported coin and / or paper money. The inner structure 2 is placed on a foundation base 4 made of concrete and anchored therein. The foundation base 4 is sunk in the ground 5, but may protrude partly from the ground 5. To protect the sensitive interior structure 2 from weather and vandalism this is enclosed by a housing 6, which is designed as downwardly open but otherwise substantially closed hood. By the housing 6 has no removal opening for the cash register 3 in the form of doors, flaps or drawers, attack points for a violent opening of the housing 6 are avoided and thereby increases the security of the parking ticket machine 1 according to the invention.

Des Weiteren umfasst der erfindungsgemäße Parkscheinautomat 1 gemäß FIG 1 ein Schließsystem zum Schutz der Kasse 3 vor unbefugtem Zugriff. Dieses Schließsystem weist eine im Gehäuse 6 angeordnete Verriegelungseinrichtung 7 auf, mittels derer beispielsweise das Gehäuse 6 mit dem Innenaufbau 2 verriegelbar ist. Die Verriegelungseinrichtung 7 kann mechanische Riegelelemente umfassen, die über ein als Elektromotor ausgebildetes Stellglied 8 bewegbar sind. Erfindungsgemäß wird eine Schlüsselkodierung zum Ermitteln der Schließberechtigung sowie die Energie zum Betätigen der Verriegelungseinrichtung 7 durch Übertragung einer Wechselspannung von einer Sendeeinheit 9 zu einer mit dieser in Wechselwirkung bringbaren Empfangseinheit 10 übersendet. Die Sendeeinheit 9 ist in einem tragbaren Handgerät 11 angeordnet, welches von einem Wartungspersonal zur Entnahme oder Leerung der Kasse 3 mitgeführt wird. Die Empfangseinheit 10 ist an einer Innenseite des Gehäuses 6 angeordnet.Furthermore, the parking ticket machine 1 according to the invention according to FIG. 1 comprises a locking system for protecting the cash register 3 against unauthorized access. This locking system has a locking device 7 arranged in the housing 6, by means of which, for example, the housing 6 can be locked to the internal structure 2. The locking device 7 may comprise mechanical locking elements, which are movable via an actuator 8 designed as an electric motor. According to the invention, a key coding for determining the locking authorization as well as the energy for actuating the locking device 7 by transmitting an alternating voltage from a transmitting unit 9 is transmitted to a receiving unit 10 which can be brought into interaction therewith. The transmitting unit 9 is arranged in a portable handset 11, which is carried by a maintenance personnel for removal or emptying of the cash register 3. The receiving unit 10 is arranged on an inner side of the housing 6.

Damit die Sendeeinheit 9 und die Empfangseinheit 10 in Wechselwirkung treten können, müssen sie durch entsprechendes Positionieren des Handgerätes 11 direkt aneinander gehalten werden, da es sich um eine sehr kurzreichweitige Übertragungsdistanz D handelt. Eine derart kurzreichweitige Übertragung gewährleistet, dass die übertragene Schlüsselkodierung nicht von Unbefugten abgehört werden kann. Die Position der Sendeeinheit 9 innerhalb des Handgerätes 11 und auch die Position der Empfangseinheit 10 innerhalb des Gehäuses 6 sind jeweils von außen nicht sichtbar, so dass eine erfolgreiche Wechselwirkung bzw. Übertragung nur befugten Personen möglich ist, die in Kenntnis dieser Positionen sind.In order for the transmitting unit 9 and the receiving unit 10 to be able to interact, they must be held directly by appropriate positioning of the hand-held device 11, since this is a very short-range transmission distance D. Such a short-range transmission ensures that the transmitted key coding can not be eavesdropped by unauthorized persons. The position of the transmitting unit 9 within the handset 11 and also the position of the receiving unit 10 within the housing 6 are each not visible from the outside, so that a successful interaction or transmission is only possible to authorized persons who are aware of these positions.

Eine Sendeeinheit 9 weist gemäß FIG 2 eine Spannungsquelle 12, etwa eine 9 V liefernde Batterie oder einen entsprechenden Akkumulator, auf. Des Weiteren weist die Sendeeinheit 9 als Mikroprozessor ausgebildete Mittel 13 auf, womit sich eine Wechselspannung Uf~ mit vorgebbarer Frequenz f erzeugen lässt. Außerdem lässt sich mit den Prozessormitteln 12 der Wechselspannung Uf~ ein Signal mit einer Schlüsselkodierung K für das Schließsystem aufprägen. Der Kodierungsschlüssel K kann als Taktfolge aus den Zeichen "0" und "1" aufgebaut sein, wobei diese Zeichen durch zeitlich unterschiedlich lange Pulse realisierbar sind. Wird durch Betätigen eines Tasters 14 am Handgerät 11 der Stromkreis in der Sendeeinheit 9 geschlossen, so liegt an einer Sendespule 15 die Wechselspannung Uf~ mit einem aufgeprägten Signal mit Schlüsselkodierung K an.According to FIG. 2, a transmitting unit 9 has a voltage source 12, for example a 9 V supplying battery or a corresponding accumulator. Furthermore, the transmitting unit 9 has a microprocessor-designed means 13, with which an alternating voltage U f ~ can be generated with a predeterminable frequency f. In addition, with the processor means 12 of the AC voltage U f ~ imprint a signal with a key coding K for the locking system. The coding key K can be constructed as a clock sequence from the characters "0" and "1", whereby these characters can be realized by pulses of different duration. Is closed by pressing a button 14 on the handset 11 of the circuit in the transmitting unit 9, so is applied to a transmitting coil 15, the AC voltage U f ~ with an impressed signal with key encoding K on.

Wird die Sendespule 15 der Sendeeinheit 9, wie in FIG 2 dargestellt, auf Übertragungsreichweite D an eine Empfangsspule 16 der Empfangseinheit 10 herangeführt, so bilden diese einen Lufttransformator, in dem die primärseitige Sendespule 15 und die sekundärseitige Empfangsspule 16 induktiv gekoppelt und lediglich durch die Wand des Gehäuses 6 voneinander getrennt sind. Die auf die Empfangsspule 16 übertragene Wechselspannung Uf~ wird gleichgerichtet und gespeichert, wofür die Mittel 17 eine Gleichrichterbrücke und die Mittel 18 einen Kondensator enthalten. Ferner weisen die Mittel 19 ein Filter für der übertragenen Wechselspannung Uf~ aufgeprägte Signale mit Kodierung auf. Das ausgefilterte Signal wird in Auswertemitteln 20 hinsichtlich der Gültigkeit der übertragenen Kodierung ausgewertet. Die Auswertemittel 20 sind durch einen Mikroprozessor gebildet, der einen Vergleich der übertragenen Kodierung mit einer hinterlegten Schlüsselkodierung K durchführt. Liegt eine Gültigkeit der übertragenen Schlüsselkodierung K vor, so wird durch Schließen des Schalters 21 die in den Speichermitteln 18 gespeicherte Energie dem Stellglied 8 zum Betätigen der Verriegelungseinrichtung 7 zugeführt.If the transmitting coil 15 of the transmitting unit 9, as shown in FIG 2, brought to transmission range D to a receiving coil 16 of the receiving unit 10, so they form an air transformer in which the primary-side transmitting coil 15 and the secondary-side receiving coil 16 inductively coupled and only through the wall of the housing 6 are separated from each other. The transmitted to the receiving coil 16 AC voltage U f ~ is rectified and stored, for which the means 17 a rectifier bridge and the means 18 include a capacitor. Furthermore, the means 19 comprise a filter for the transmitted AC voltage U f ~ impressed signals with coding. The filtered-out signal is evaluated in evaluation means 20 with regard to the validity of the transmitted coding. The evaluation means 20 are formed by a microprocessor, which performs a comparison of the transmitted coding with a stored key coding K. If a validity of the transmitted key code K is present, the energy stored in the storage means 18 is supplied to the actuator 8 for actuating the locking device 7 by closing the switch 21.
