Abstract

The device comprises a metal reflector movable between a retracted position and pulled out into a working position. The radiowaves from the antenna (3) in the direction of the body or head of the user are reflected or deflected by the reflector (3), so that the radiation does not penetrate the body of the user in the direct way.The reflector is made of some material, such as aluminium, that reflect HF radio waves and it can be moved back in its grooves to the rest position when not needed.

Description

Handfunktelefone, allgemein Handys genannt, finden immer mehr Verbreitung.Hand-held radiotelephones, commonly called cell phones, are becoming increasingly popular.

Da die Energieabstrahlung bei Betrieb eines Handys in unmittelbarer Nähe des Kopfes vonstatten geht, ist eine negative Beeinflussung des Betreibers durch die ihn durchdringenden hochfrequenten Funkwellen nicht ganz auszuschließen. Das Problem wird derzeit kontrovers diskutiert.Since the energy radiation when operating a cell phone in the immediate vicinity of the Is a negative influence on the operator by the operator not completely excluding high-frequency radio waves penetrating it. The The problem is currently being discussed controversially.

Gegenstand dieser Erfindung ist es, das Gefährdungsrisiko eines "Handybetreibers" zu minimieren bzw. völlig auszuschließen. Erfindungsmäßig wird das dadurch erreicht, daß der Funkstrahl der Handyantenne in Richtung des Körpers, vornehmlich des Kopfes, durch einen metallischen Reflektor dergestalt abgelenkt, bzw. reflektiert wird, daß die Funkwellen den Körper des Telefonierenden nicht mehr auf direktem Wege durchdringen können und somit eine Minimierung der möglicherweise schädlichen Einflüsse der elektromagnetischen Wellen von Mobilfunkgeräten, hier, die sog. Handys, verhindert.The object of this invention is to reduce the risk of danger To minimize or completely exclude "mobile phone operator". According to the invention this is achieved in that the radio beam of the cell phone antenna in the direction of Body, mainly the head, by a metallic reflector is deflected or reflected that the radio waves the body of the Can no longer penetrate the phone directly and thus a minimization of the potentially harmful influences of the electromagnetic waves from mobile devices, here, the so-called cell phones, prevented.

Der Funkbetrieb wird durch diese Maßnahme, wenn überhaupt, nur unwesentlich beeinträchtigt, da durch Reflexion von anderen Gegenständen der Umgebung, die Empfänger bzw. Relaisstation auch erreicht werden können. Erforderlichenfalls müßte sich der Nutzer etwas drehen.The radio operation becomes insignificant, if at all, by this measure impaired because of reflection from other objects in the area, the Receiver or relay station can also be reached. If necessary the user would have to turn something.

Die Fig. 1 zeigt das Handy (1) mit der außen sichtbaren Antenne (3) und dem Reflektor (2) im "Ruhezustand". Fig. 1 shows the cell phone ( 1 ) with the externally visible antenna ( 3 ) and the reflector ( 2 ) in the "idle state".

Die Fig. 2 und 3 zeigen das Handy im Betriebszustand von der Seite und von vorne. Der Reflektor befindet sich in ausgeschobener Position. Figs. 2 and 3 illustrate the mobile phone in the operating state from the side and from the front. The reflector is in the extended position.

Die Fig. 4 zeigt eine mögliche Variante mit einem innerhalb des Handys integrierten Reflektor und Antenne. FIG. 4 shows a possible variant with an integrated within the mobile phone and antenna reflector.

Claims (3)

1. Schutzvorrichtung gegen hochfrequente elektromagnetische "Strahlen" vornehmlich an "Handys" einsetzbar, dadurch gekennzeichnet, daß die Funkwellen der Handyantenne (3) in Richtung des Körpers/ Kopfes durch einen Reflektor (2) dergestalt abgelenkt bzw. reflektiert werden, so daß die Funkstrahlen den Nutzer nicht auf direktem Wege durchdringen können.1.
