Abstract
Schutztasche zum Schutz vor elektromagnetischer Strahlung und zur Funkabschirmung, dadurch gekennzeichnet, dass die Schutztasche zum Schutz vor elektromagnetischer Ein- und Ausstrahlung dient.Protective bag for protection against electromagnetic radiation and radio shielding, characterized in that the protective bag is used to protect against electromagnetic input and radiation.
Description
Die Vorrichtung dient zum Schutz vor elektromagnetischen Strahlungen und zur Abschirmung von Funkstrahlungen in unterschiedlichen Frequenzbereichen.The device is used to protect against electromagnetic radiation and to shield radio emissions in different frequency ranges.
Funksender werden u. a. im KFZ Bereich zur Öffnung von Fahrzeugtüren und zum Start von Fahrzeugen u. a. in der Technologie KEYLESS GO verwendet. Weitere Anwendungen ergeben sich durch die Nutzung von Mobiltelefonen und Handsendern zur Betätigung von Toren und Einfahrten zu Garagen. Dabei sendet ein Sender Signale zu einem Empfänger der diese wiederum auswertet und ggf. im codierten Modus eine Kommunikation zwischen dem Sender und Empfänger dauerhaft oder nur zyklisch zulässt. Diese Systeme arbeiten hauptsächlich auf sehr kurzen Distanzen von wenigen Zentimetern bis zu mehreren Metern. Durch diese geringe Reichweite dieser Systeme soll es nur möglich sein diese Vorrichtungen oder Fahrzeuge in der unmittelbaren Umgebung des Nutzes zu öffnen oder zu starten. Jedoch ist es durch geeignete elektronischen Maßnahmen (Funkverstärker) möglich, die voreingestellt Reichweite dieser Systeme zu vergrößern und diese Funksysteme auch über größere Distanzen von mehreren 10 Metern bis zu 300 Metern oder auch noch größere Entfernungen zu überbrücken. Dadurch wird somit die Nutzung Dritter, nicht berechtigter Personen ebenso möglich. Funkverstärker arbeiten u. a. auf Basis der Verstärkung der vorhandenen Funksignale ohne wesentliche Beeinflussung der Qualität des originalen Funksignales. Es ist also erforderlich diese selbsttätige Funkstrahlung des Handsenders – durch die jeweilige Technologie der Kommunikationstechnik bedingt – während der Nichtnutzung eines Fahrzeuges oder einer Anlage bzw. eines Mobiltelefons wie oben beschrieben wirksam zu unterdrücken.Radio transmitters are u. a. in the vehicle area for the opening of vehicle doors and for the start of vehicles u. a. used in technology KEYLESS GO. Further applications result from the use of mobile telephones and hand transmitters for the operation of gates and driveways to garages. In this case, a sender sends signals to a receiver which, in turn, evaluates them and, if appropriate, permits communication between the transmitter and receiver permanently or only cyclically in the coded mode. These systems work mainly at very short distances from a few centimeters to several meters. Due to this short range of these systems, it should only be possible to open or start these devices or vehicles in the immediate vicinity of the utility. However, with suitable electronic measures (radio amplifiers) it is possible to increase the preset range of these systems and to bridge these radio systems even over greater distances of several tens of meters up to 300 meters or even greater distances. Thus, the use of third parties, unauthorized persons is also possible. Radio amplifiers work u. a. based on the amplification of the existing radio signals without significantly affecting the quality of the original radio signal. It is therefore necessary to effectively suppress this self-acting radio radiation of the hand-held transmitter - due to the respective technology of the communication technology - during the non-use of a vehicle or a system or a mobile telephone as described above.
Dieses Problem wird mit den im Schutzanspruch 1 aufgeführten Merkmalen gelöst.This problem is solved with the features listed in the
Die Schutztasche besteht im Inneren aus einer geschlossenen metallischen Oberfläche welche in Form eines Gewebes ausgebildet ist. Diese Metallschicht kann als Aluminiumschicht auf das Grundgewebe aufgetragen werden und ist dauerhaft haltbar. Der wesentliche Vorteil dieses Gewebes besteht darin dass es eine hohe Flexibilität aufweisst und dadurch ebenfalls einen guten Haftgrund für eine metallische Oberfläche darstellt. Durch diesen Schichtaufbau ergibt sich ebenfalls eine hohe Flexibilität der Schutztasche. Diese kann sich dadurch flexibel z. B. an die Hosentasche des Benutzers anpassen. Metallboxen welche ebenfalls diese Aufgabe erfüllen könnten besitzen im Gegensatz dazu keine Flexibilität und bieten keine Tragekomfort für den Benutzer.The protective bag consists inside of a closed metallic surface which is formed in the form of a fabric. This metal layer can be applied as an aluminum layer on the base fabric and is durable. The main advantage of this fabric is that it has a high degree of flexibility and thus also provides a good primer for a metallic surface. By this layer structure also results in a high flexibility of the protective bag. This can be flexible z. B. to the trouser pocket of the user. In contrast, metal boxes which could also fulfill this task have no flexibility and offer no wearing comfort for the user.
Mit der Erfindung wird erreicht, dass eine dauerhafte bzw. zyklische Funkverbindung zwischen einem Funkschlüssel und einem Funkempfänger wie diese u. a. im Bereich der Keyless Go Schlüsseltechnologie im KFZ Bereich angewendet wird, wirksam unterdrückt bzw. stark eingeschränkt wird.With the invention it is achieved that a permanent or cyclic radio connection between a radio key and a radio receiver such as this u. a. In the field of Keyless Go key technology in the automotive sector is applied, effectively suppressed or severely restricted.
Funktion:Function:
Durch das Einlegen eines Funksender oder auch Funkschlüssels in die Schutztasche wird eine Abschirmung der Funkstrahlung dadurch erreicht, dass durch die geschlossene Innenschicht auf Metallbasis eine geschlossene metallische Schutzhülle entsteht. Aus dem Stand der Technik ist bekannt dass diese geschlossenen Metalloberflächen Funkstrahlungen in unterschiedlichen Frequenzbereichen räumlich vor der Ausbreitung abschirmen und somit ein Funksignal an der räumlichen Ausbreitung hindern bzw. den Empfang von elektromagnetischen Strahlen/Strahlung abschirmen.By inserting a radio transmitter or radio key into the protective bag, a shielding of the radio radiation is achieved in that the closed inner layer based on metal creates a closed metallic protective cover. It is known from the prior art that these closed metal surfaces spatially shield radio radiation in different frequency ranges from propagation and thus prevent a radio signal from propagating in space or shield the reception of electromagnetic radiation / radiation.
