Objektobject
Beschreibungdescription
Die Erfindung bezieht sich auf eine Einrichtung zur Kontrolle des Türverschlußzustandes an einem Objekt, insbesondere an einem Unterhaltungsgerät oder einem Kraftfahrzeug, mittels eines elektronischen Schlüssels, der einen Sender aufweist, welcher mit einem am Objekt angeordneten Empfänger innerhalb eines definierten räumlichen Bereiches in Kommunikationsver¬ bindung steht, wobei am Objekt und/oder am elektronischen Schlüssel eine Signaleinrichtung vorgesehen ist.The invention relates to a device for checking the state of the door lock on an object, in particular on an entertainment device or a motor vehicle, by means of an electronic key which has a transmitter which is in communication connection with a receiver arranged on the object within a defined spatial area , wherein a signal device is provided on the object and / or on the electronic key.
In den vergangenen Jahren wird dem Schutz von insbesondere Unterhaltungsgeräten, wie Spielautomaten, Geldspielgeräten und dergleichen, sowie Kraftfahrzeugen gegen Einbruch und Diebstahl besondere Aufmerksamkeit geschenkt. Dazu werden um¬ fangreiche Überlegungen angestellt und technische Maßnahmen realisiert, um die Unterhaltungsgeräte und Kraftfahrzeuge mit vorzugsweise elektronischen Sicherheitssystemen auszurüsten, die unberechtigten Personen den Zugang zu einem solchen Un¬ terhaltungsgerät oder zum Kraftfahrzeug erschweren bzw. voll¬ ständig verhindern sollen. Dazu werden beispielsweise die Kraftfahrzeuge mit elektronischen Diebstahlsicherungen, Weg¬ fahrsperren und Alarmanlagen versehen. Derartige elektroni¬ sche Systeme sind oftmals mit im „scharfen" Zustand leuchten¬ den elektronischen Anzeigen in Form von Leuchtdioden verse- hen, die anzeigen, ob eine Alarmanlage, Diebstahlsicherung oder Wegfahrsperre eingeschaltet ist.In recent years, special attention has been paid to protecting in particular entertainment devices, such as gaming machines, gaming machines and the like, and motor vehicles against burglary and theft. To this end, extensive considerations are made and technical measures are implemented in order to equip the entertainment devices and motor vehicles with preferably electronic security systems which are intended to make unauthorized persons more difficult or completely prevent access to such an entertainment device or to the motor vehicle. For this purpose, for example, the motor vehicles are provided with electronic anti-theft devices, immobilizers and alarm systems. Electronic systems of this type are often equipped with electronic displays in the form of light-emitting diodes which shine in the “sharp” state. that indicate whether an alarm system, anti-theft device or immobilizer is switched on.
Besonderes Hauptaugenmerk wird auf die Zugangselemente des Unterhaltungsgerates bzw. des Kraftfahrzeuges, die Türen, ge¬ richtet. Unter dem Begriff „Türen" sollen hieroei alle Arten von Zugangen zu einem Objekt beliebiger Art verstanden wer¬ den. Darunter zahlen u.a. Jalousien, Garagentore, Klappen und dergleichen. Zunehmend werden die Türen mit elektronischen Schlossern versehen, die über einen elektronischen Schlüssel, vorzugsweise eine Fernbedienung bedienbar sind. Im allgemei¬ nen ist es nur dem Inhaber des elektronischen Schlusseis mög¬ lich, die Türen zu offnen und zuschließen.Particular attention is paid to the access elements of the entertainment device or the motor vehicle, the doors. The term “doors” is to be understood here to mean all types of access to an object of any type. These include, among other things, blinds, garage doors, flaps and the like. Increasingly, the doors are provided with electronic locks which have an electronic key, preferably one In general, it is only possible for the holder of the electronic key to open and close the doors.
Aus der nicht vorveroffentlichten PCT/DE96/00090 ist eine Einrichtung zur Kontrolle des Türverschlußzustandes, insbe¬ sondere an einem Kraftfahrzeug bekannt, welche eine getrennt vom Objekt handhabbaren elektronischen Schlüssel verwendet, wobei dieser elektronische Schlüssel und das Objekt jeweils eine Sender-/Empfangereιnheιt aufweisen. Darüber hinaus ver¬ fugen der elektronische Schlüssel sowie das Objekt jeweils über eine optische Anzeige in Form von Leuchtdioden. Über Verschluß-Erfassungssensoren am Objekt wird der „Offen"- bzw. „Verschlossen"-Zustand beispielsweise der Tur eines Kraft¬ fahrzeuges erfaßt und ein entsprechendes Signal an den elek¬ tronischen Schlüssel angegeben. Dabei kann ein an der Außen¬ seite der Kraftfahrzeugtur und/oder am elektroniscnen Schlüs¬ sel angebrachtes akustisches Wiedergabeelement aufleuchten. Somit wird ein visuell wahrnehmbares Signal am Objekt bzw. am elektronischen Schlüssel erzeugt. Dies hat jedoch den Nach¬ teil, daß dieses visuelle Signal bei Tageslicht, insbesondere bei starkem Sonnenlicht unter Umstanden nicht wahrgenommen werden kann, da die Lichtstarke der Sonnenstrahlung die Lichtstarkde der optischen Anzeige übersteigt. Wenn die opti- sehe Anzeige beispielsweise nur am Objekt angebracht ist, ist dieses bei hinreichend großem Abstand oftmals nicht menr er¬ kennbar. Ein weiterer Nachteil besteht auch darin, daß, wenn versäumt wurde, die Tur des Objektes zu verschließen und so¬ mit die optischen Anzeigen nicht aufleuchten, unberechtigte Personen sofort über den „Offen"-Zustand des Objektes infor¬ miert werden und es dadurch zu Einbrüchen oder Diebstahlen kommen kann.From the unpublished PCT / DE96 / 00090 a device for checking the state of the door lock, in particular on a motor vehicle, is known which uses an electronic key that can be handled separately from the object, this electronic key and the object each having a transmitter / receiver unit. In addition, the electronic key and the object each have an optical display in the form of light-emitting diodes. The “open” or “closed” state, for example the door of a motor vehicle, is detected by means of lock detection sensors on the object and a corresponding signal is given to the electronic key. An acoustic reproduction element attached to the outside of the motor vehicle door and / or to the electronic key can light up. This creates a visually perceptible signal on the object or on the electronic key. However, this has the disadvantage that this visual signal cannot be perceived in daylight, especially in strong sunlight, since the intensity of the solar radiation exceeds the intensity of the optical display. If the opti- see display, for example, is only attached to the object, this is often not recognizable at a sufficiently large distance. Another disadvantage is that if the door of the object is not locked and the optical displays do not light up, unauthorized persons are immediately informed of the "open" state of the object and this leads to break-ins or theft can occur.
Bekannt ist auch ein elektronischer Schlüssel, der als Fern¬ bedienung ausgebildet ist, der bei Betätigung einer Taste die Türen eines Kraftfanrzeuges entriegelt. Beim Verlassen des Kraftfahrzeuges können durch Betätigung einer weiteren Taste am elektronischen Schlüssel alle Türen des Kraftfahrzeuges verriegelt werden. Die Türen sind mit Verschluß- Erfassungssensoren versehen, die mit einer im Kraftfahrzeug befindlichen Empfangereinheit in KommunikationsVerbindung stehen. Will der Benutzer des Kraftfahrzeuges prüfen, ob alle Türen des Kraftfahrzeuges verschlossen sind, kann er inner¬ halb eines räumlich begrenzten Bereiches die Turverriege- lungstaste am elektronischen Schlüssel nochmals betätigen. Sind alle Türen verschlossen, gibt die im Kraftfahrzeug in¬ stallierte Empfangereinheit einen Impuls an die akustische Signaleinrichtung, die Fahrzeughupe, die dann durch einen kurzen akustischen Hupton die Turvemegelung bestätigt. Ist eine der Türen nicht verriegelt, unterbleibt das akustische Signal. Ein besonderer Nachteil dieser Einrichtung ist, daß in akustisch lauter Umgebung das akustische Signal oftmals nicht wahrnehmbar ist oder nicht dem jeweiligen Kraftfahrzeug zugeordnet werden kann. Eine Ruckversicherung darüber, ob die Türen des Kraftfahrzeuges tatsächlich verschlossen sind, kann immer nur durch wiederholtes Betatigen der Verπegelungstaste am elektronischen Schlüssel erfolgen, wobei jedesmal erneut ein lauter Hupton vom Kraftfahrzeug erzeugt wird, der als störend empfunden wird.Also known is an electronic key which is designed as a remote control which unlocks the doors of a motor vehicle when a key is pressed. When leaving the motor vehicle, all the doors of the motor vehicle can be locked by pressing a further key on the electronic key. The doors are provided with locking detection sensors which are in communication with a receiver unit located in the motor vehicle. If the user of the motor vehicle wants to check whether all the doors of the motor vehicle are locked, he can press the door lock button on the electronic key again within a spatially limited area. If all doors are closed, the receiver unit installed in the motor vehicle gives an impulse to the acoustic signal device, the vehicle horn, which then confirms the turn regulation by a short acoustic horn. If one of the doors is not locked, the acoustic signal is not activated. A particular disadvantage of this device is that in an acoustically noisy environment the acoustic signal is often imperceptible or cannot be assigned to the respective motor vehicle. A reinsurance of whether the doors of the motor vehicle are actually locked can only be done by repeatedly pressing the lock button on the electronic key, each time again a loud horn sound is generated by the motor vehicle, which is perceived as annoying.
Es ist daher Aufgabe der vorliegenden Erfindung, eine Ein¬ richtung zur Kontrolle des Türverschlußzustandes an einem Ob¬ jekt, insbesondere an einem Unterhaltungsgerät oder einem Kraftfahrzeug, zu schaffen, mit der akustisch wahrnehmbare Signale getrennt vom Objekt erzeugt werden, um dem Benutzer nach dem Verlassen des Objektes den „Offen"- bzw. „Verschlossen"-Zustand der Türen übermitteln zu können.It is therefore an object of the present invention to provide a device for checking the state of the door lock on an object, in particular on an entertainment device or a motor vehicle, with which acoustically perceptible signals are generated separately from the object in order to inform the user after leaving of the object to be able to transmit the "open" or "closed" state of the doors.
Erfindungsgemäß wird die Aufgabe dadurch gelöst, daß der elektronische Schlüssel zusätzlich einen Empfänger und das Objekt weiterhin einen mit diesem in Kommunikationsverbindung stehenden Sender aufweist, und daß die Signaleinrichtung ein akustisches Wiedergabeelement am elektronischen Schlüssel zur tastengesteuerten Signalisierung des „Offen-" bzw. „Verschlossen"-Zustandes der Tür ist.According to the invention, the object is achieved in that the electronic key additionally has a receiver and the object also has a transmitter that is in communication with it, and in that the signal device has an acoustic reproduction element on the electronic key for key-controlled signaling of the “open” or “locked” -The condition of the door is.
Durch diese Maßnahmen wird eine akustisch wahrnehmbare Ton¬ wiedergabe am elektronischen Schlüssel bei Betätigen einer Taste dieses Schlüssels erreicht, d.h. der Benutzer des Schlüssels erhält jederzeit eine akustische Rückmeldung über den Verschlußzustand der Tür. Durch Betätigen einer entspre¬ chenden Taste am elektronischen Schlüssel sendet der Sender der im Objekt installierten Sender/Empfängereinheit ein Si¬ gnal an den elektronischen Schlüssel, der das akustische Wie¬ dergabeelement am elektronischen Schlüssel aktiviert. Da der Benutzer des elektronischen Schlüssels diesen beim Verlassen des Objektes bei sich trägt, kann er in einem stark begrenz¬ ten räumlichen Bereich, nämlich in seinem unmittelbaren Umge¬ bungsfeld, den erzeugten akustischen Ton hören, ohne daß um¬ stehende Personen hierdurch belästigt werden. Selbstverständ¬ lich kann der Sender des elektronischen Schlüssels gleicher- maßen auch em Signal an das im Objekt angebrachte akustische Wiedergabelement, beispielsweise die Hupe eines Kraftfahrzeu¬ ges, übermitteln, das akustisch wahrnehmbar ist. Der Empfan¬ ger im Objekt ist zur Aufnahme des über den im elektronischen Schlüssel angebrachten Senders abgegebenen Impulses vorgese¬ hen. Neben einem Kraftfahrzeug kann das Objekt natürlich auch em Unterhaltungsgerat, wie z.B. ein Geldspielgerat, ein Wurfpfeilspielgerat, em Musikautomat oder dergleichen sein.These measures result in an acoustically perceptible sound reproduction on the electronic key when a key of this key is actuated, ie the user of the key receives acoustic feedback at all times about the locked state of the door. By actuating a corresponding key on the electronic key, the transmitter of the transmitter / receiver unit installed in the object sends a signal to the electronic key, which activates the acoustic reproduction element on the electronic key. Since the user of the electronic key carries the electronic key with him when he leaves the object, he can hear the acoustic sound generated in a very limited spatial area, namely in his immediate surroundings, without being bothered by bystanders. Of course, the transmitter of the electronic key can also transmit a signal to the acoustic display element attached to the object, for example the horn of a motor vehicle, which is acoustically perceptible. The receiver in the object is intended to receive the pulse emitted by the transmitter attached in the electronic key. In addition to a motor vehicle, the object can of course also be an entertainment device, such as a gaming machine, a dart game device, a music machine or the like.
Bevorzugt besteht das akustische Widergabeelement aus einem einen Ton oder eine Tonfolge erzeugenden elektrischen oder elektronischen Bauelement. Dabei ist es auch möglich, eme kurze Tonfolge in Form einer Melodie oder einer sprachlichen Wiedergabe zu erzeugen.The acoustic reproduction element preferably consists of an electrical or electronic component that generates a tone or a tone sequence. It is also possible to create a short sequence of tones in the form of a melody or a speech.
In weiterer Ausbildung der Erfindung ist zur Kontrolle des Verschlußzustandes der Tur bzw. der Türen eines Kraftfahrzeu¬ ges zusätzlich die Kofferraumklappe und/oder die Motorraum¬ klappe vorgesehen. Dadurch werden im Prinzip alle Zugange des Kraftfahrzeuges in die Verschlußkontrolle einbezogen. Neben der Kontrolle des Türverschlußzustandes des Kraftfahrzeuges wird somit der Zugang von unberechtigten Personen zum Kraft¬ fahrzeug und dessen Diebstahl erschwert.In a further embodiment of the invention, the trunk flap and / or the engine compartment flap is additionally provided for checking the closed state of the door or the doors of a motor vehicle. In principle, this means that all accesses to the motor vehicle are included in the lock control. In addition to checking the state of the door lock of the motor vehicle, the access of unauthorized persons to the motor vehicle and its theft is thus made more difficult.
Um den Turverschlußzustand am Objekt ermitteln zu können, ist bevorzugt an der Tur bzw. der Klappe em Verschluß- Erfassungssensor angeordnet, der mit der Sen¬ der/Empfangereinheit des Objektes verbunden ist.In order to be able to determine the state of the door lock on the object, a lock detection sensor is preferably arranged on the door or the flap, which sensor is connected to the transmitter / receiver unit of the object.
