Abstract
Description
Die Erfindung betrifft einen Überzug für Sende- und Empfangsgeräte.The invention relates to a coating for broadcast and Receivers.
Dabei kann es sich sowohl um mobile, als auch um stationäre Geräte handeln. Sender und Empfänger können auch in einem Gerät vereinigt sein, wie es z. B. bei mobilen Telephonen, den sog. "Handies", und gewissen verschiedenen Funkgeräten, wie "Walky-Talkies", der Fall ist. Andere Beispiele, bei denen die vorliegende Erfindung zum Einsatz kommen kann, sind Radioempfänger, insbesondere Radiowecker, und Babyphone.It can be both mobile and stationary Trade devices. Sender and receiver can also be in one Device be united, as z. B. in mobile telephones So-called "cell phones", and certain different radio devices, such as "Walky-Talkies", the case is. Other examples where the present invention can be used Radio receivers, in particular clock radios, and baby monitors.
Allen diesen Geräten gemeinsam ist, daß der Benutzer beson ders während des Sendebetriebs einer nicht unerheblichen elektromagnetischen Strahlung ausgesetzt ist. Aber auch be reits im Standby-Betrieb emittieren sie elektromagnetische Felder, den sog. "Elektrosmog", der die Benutzer gesundheit lich beeinträchtigen kann. Insbesondere für Handies ist zudem nachgewiesen, daß sie einen störenden und deregulierenden Einfluß auf Herzschrittmacher ausüben können, so daß deren Träger besonders gefährdet sind.All these devices have in common that the user a not inconsiderable one during broadcasting is exposed to electromagnetic radiation. But also be They already emit electromagnetic signals in standby mode Fields, the so-called "electrosmog", which health users Lich can affect. Especially for cell phones is also proven that they are bothersome and deregulating Can influence pacemakers so that their Carriers are particularly at risk.
Davon ausgehend ist es Aufgabe der vorliegenden Erfindung, eine Vorrichtung bereitzustellen, durch deren Einsatz diese gesundheitsbeeinträchtigenden Wirkungen von Sende- und Empfangsgeräten vermindert werden können.Based on this, it is an object of the present invention to provide a device through the use of which adverse health effects of broadcast and Receivers can be reduced.
Gelöst wird diese Aufgabe durch einen Überzug, der vorwiegend aus einem elektromagnetisch abschirmenden Material herge stellt ist. In Frage kommt hierfür insbesondere ein metalli scher oder metallisierter Werkstoff mit hoher elektromagneti scher Abschirmeigenschaft, wie z. B. eine Nickel-Kupferlegie rung. Dieser Werkstoff kann in Form einer Folie, eines Gewe bes, Gewirks oder einer Art Filz aus Metallfäden, eines mit Metallitzen durchwirkten oder mit Metallpartikeln bedampften Stoffes oder einer solchen Kunststoffolie vorliegen. Möglich ist es auch, den Überzug Mithilfe eines Metallsprays auf die Sende- und Empfangsgeräte aufzubringen. Je nach verwendetem Material kann der Überzug im wesentlichen unlösbar mit dem Sende- und Empfangsgerät, z. B. durch Aufkleben, verbunden sein oder abnehmbar als eine Art von "Schutzhaube" gestaltet sein.This task is solved by a coating that predominantly made of an electromagnetic shielding material represents is. A metalli is particularly suitable for this shear or metallized material with high electromagnetic shear shielding property such. B. a nickel-copper alloy tion. This material can be in the form of a film, a fabric bes, knitted or a kind of felt from metal threads, one with Knocked through metal strands or steamed with metal particles Substance or such a plastic film are present. Possible It is also possible to apply the coating to the surface using a metal spray Applying transmitters and receivers. Depending on the used The coating can be essentially insoluble with the material Transmitting and receiving device, e.g. B. connected by gluing be removable or designed as a kind of "protective cover" be.
Dabei bedeckt dieser Überzug erfindungsgemäß zumindest einen Teil der Außenfläche des Gerätegehäuses und der Antenne. Zweckmäßigerweise bleiben Anzeigen- und Bedienvorrichtungen, wie Displays, Leuchtdioden, Tastaturen, elektrische Schalter und Drehknöpfe, frei und sind nicht von dem Überzug über deckt. Dazu kann der Überzug fensterartige Aussparungen auf weisen.According to the invention, this coating covers at least one Part of the outer surface of the device housing and the antenna. Appropriately, display and operating devices remain such as displays, light emitting diodes, keyboards, electrical switches and knobs, free and are not overcoated covers. For this purpose, the cover can have window-like recesses point.
Ist die Antenne vollständig von dem Überzug eingeschlossen, kann dies zu einer erheblichen Verminderung der Sendeleistung und Empfangsempfindlichkeit führen. Erfindungsgemäß ist des halb vorgesehen, nur die dem Benutzer zugewandte Seite oder Halbfläche der Antenne durch den Überzug elektromagnetisch abzuschirmen.If the antenna is completely enclosed by the coating, this can lead to a significant reduction in the transmission power and reception sensitivity. According to the half intended, only the side facing the user or Half surface of the antenna through the coating electromagnetic shield.
Die Abschirmwirkung des Überzugs kann weiterhin dadurch wesentlich verbessert werden, daß dieser geerdet ist. Im Fall eines Handy′s kann eine solche Erdung vorteilhaft dadurch er folgen, daß zwischen dem Überzug und der Buchse für den An schluß an das Ladegerät ein elektrischer Kontakt herstellbar ist. Dazu kann beispielsweise ein Kabel elektrisch leitend an den Überzug angeschlossen werden, an dessen anderem Ende ein Stecker sitzt, der mit dieser Buchse in Eingriff bringbar ist.The shielding effect of the coating can continue be significantly improved that this is grounded. In the case Such a grounding of a cell phone can be advantageous follow that between the coating and the socket for the on electrical contact can be made to the charger is. For example, a cable can be electrically conductive be connected to the coating at the other end Plug sits, which can be brought into engagement with this socket is.
Im folgenden wird eine Ausführungsform der Erfindung anhand der beiliegenden Zeichnung näher erläutert. Von den Figuren zeigen:In the following, an embodiment of the invention will be described the accompanying drawing explained. From the figures demonstrate:
Fig. 1 die Vorderansicht eines mit einem erfindungsge mäßen Überzug versehenen Handy′s; Figure 1 is a front view of a cell phone provided with a coating according to the invention;
Fig. 2 die Rückansicht dieses Handy′s. Fig. 2 is the rear view of this cell phone.
In Fig. 1 ist der erfindungsgemäße Überzug 1 als Abschirmvor richtung für ein Handy 2 dargestellt. Der Überzug 1 besteht im wesentlichen aus einem Metallgewebe, das sich der Form unterschiedlicher Handytypen gut anpaßt. Er bedeckt die dem Benutzer zugewandte Seite der Antenne 3 und einen Teil der Außenfläche des Gehäuses 4. Insbesondere das Display 5 und die Funktions- und Wähltasten 6 bleiben frei. Zu seiner Befe stigung an der Antenne 3 weist der Überzug 1 eine Kappe 7 auf, die auf die Antennenspitze aufgesteckt ist.In Fig. 1, the coating 1 of the invention is shown as Abschirmvor direction for a cell phone 2 . The cover 1 consists essentially of a metal mesh that adapts well to the shape of different types of cell phones. It covers the side of the antenna 3 facing the user and part of the outer surface of the housing 4 . In particular, the display 5 and the function and selection buttons 6 remain free. To its BEFE stigung on the antenna 3 , the coating 1 has a cap 7 which is attached to the antenna tip.
In Fig. 2 ist insbesondere die Befestigung des abnehmbaren Überzugs 1 am Gehäuse 4 zu erkennen. Hierzu weist der Überzug 1 zwei Stege 8 auf, die in ihrem Überlappungsbereich durch einen Klettverschluß 9 miteinander verbunden werden können. Durch diese wiederum verschiedenen Handygrößen problemlos an paßbare Art der Befestigung sitzt der Überzug 1 verrutschsi cher auf dem Handy 2.In Fig. 2 in particular the attachment of the removable cover 1 to the housing 4 can be seen. For this purpose, the cover 1 has two webs 8 , which can be connected to one another in their overlap area by a Velcro fastener 9 . Due to this in turn different cell phone sizes easily on a suitable type of attachment, the cover 1 slips on the cell phone 2 .
