Description
Die Erfindung betrifft eine tragbare, vollständig in einem Schutzhelm eingebaute Funkwechselsprechanlage, deren Antenne, Sende- und Empfangseinrichtung, Stromversorgung, Sprechrichtungsumschalter und Hörkapseln im bzw. am Schutzhelm selbst befestigt sind und deren Mikrofon an einem in der Nähe des Ohres schwenkbar am Schutzhelm angelenkten Bügel derart angeordnet ist, daß es nach Bedarf in die Nähe des Mundes oder an die Unterseite des Schutzhelmes geschwenkt werden kann.The invention relates to a portable radio intercom system completely built into a protective helmet, their antenna, transmitting and receiving device, power supply, speech direction switch and earphones are attached in or on the helmet itself and their microphone is attached to a nearby one the ear is pivotally mounted on the helmet hinged bracket so that it is as required in the Can be swiveled near the mouth or to the underside of the protective helmet.
Derartige Funkwechselsprechanlagen sind bekannt und werden insbesondere in der Luftfahrt und im militärischen Dienst vielfach verwendet. Bei anderen bekannten im militärischen Dienst verwendeten Funkwechselsprechanlagen wird die Umschaltung von Senden auf Empfang vorzugsweise durch einen an der Dienstkleidung befindlichen Druckknopf od. ä. vorgenommen. Dies ist für Benutzer, die ihren Dienst stehend oder sitzend verrichten, vorteilhaft.Such radio intercom systems are known and are particularly used in aviation and in widely used in military service. In other known radio intercom systems used in military service the switchover from sending to receiving is preferably carried out by means of a push button or the like located on the uniform. This is advantageous for users who do their work standing or sitting.
Es ist selbstverständlich möglich, derartige Anlagen der eingangs genannten Art auch im Bergbau zur Verbindung zwischen einer Zentrale und den Steigern einzusetzen, weil sie durch Verwendung von Kleinstbauteilen, gedruckter Schaltung und Transistoren neben kleinstem Volumen auch ein äußerst geringes Gewicht aufweisen und auch noch den wesentlichen bergbaulichen Sicherheitsbestimmungen entsprechen. Es muß nämlich unter allen Umständen verhütet werden, daß ein an der Funkwechselsprechanlage befindliches stromführendes Kabel zur Auslösung der im Bergbau verwendeten elektrischen Zünder mißbraucht werden kann. Aus diesem Grunde soll eine derartige Anlage keine außerhalb des Helmes befindlichen stromführenden Kabel aufweisen, so daß nur Funkwechselsprechanlagen der eingangs genannten Art im Bergbau verwendet werden können. Bei diesen muß aber zum Sprechrichtungswechsel nicht nur der Bügel entsprechend verschwenkt werden, sondern mit einem zweiten Handgriff auch der am Schutzhelm befestigte Sprechrichtungsumschalter betätigt werden.It is of course possible to use such systems of the type mentioned at the outset in mining as well to be used for the connection between a control center and the Steigern, because they are through the use of Small components, printed circuit and transistors in addition to the smallest volume also an extremely have a low weight and also comply with the essential mining safety regulations correspond. It must be prevented under all circumstances that a radio intercom Current-carrying cable located to trigger the electrical ones used in mining Detonator can be misused. For this reason, such a system should not be outside have the helmet located live cables, so that only the radio intercoms Above mentioned type can be used in mining. With these, however, you have to change the direction of speech Not only the bracket can be swiveled accordingly, but also the speech direction switch attached to the hard hat with a second handle be operated.
Zur Verringerung der Zahl der notwendigen Handgriffe ist erfindungsgemäß der einen oder mehrere Kontakte aufweisende Sprechrichtungsumschalter im Gelenk für den Bügel (2) angeordnet und durch dessen Schwenkbewegungen betätigbar.In order to reduce the number of necessary hand movements, according to the invention, one or more Contacts having speech direction switch arranged in the joint for the bracket (2) and through whose pivoting movements can be actuated.
Nach einer Weiterbildung der Erfindung steuert der Sprechrichtungsumschalter ein im freien Innenraum oder Innenpolster des Schutzhelmes angeordnetes Kleinstrelais, welches die Sprechrichtung umschaltet. According to a further development of the invention, the speech direction switch controls a free interior space or inner padding of the protective helmet arranged miniature relay, which switches the speech direction.

besteht der Sprechrichtungsumschalter aus einem im oder am Bügel angeordneten Dauermagnet und aus an der gegenüberliegenden Unterseite des Schutzhelmes angeordneten Kontakten, die über einen Anker oder unmittelbar selbst als Ankerkontakte betätigbar sind.the speech direction switch consists of a permanent magnet arranged in or on the bracket and of on the opposite underside of the helmet arranged contacts, which have a Armature or can be actuated directly as armature contacts.
An Hand der Zeichnung wird die Erfindung näher erläutert. Die Zeichnung zeigt die Ausführung des in der Nähe des Ohres schwenkbar am Schutzhelm angelenkten Bügels mit daran befestigter Hörkapsel. Am Schutzhelm 1 ist der Bügel 2 mittels eines Gelenks 3 schwenkbar befestigt. Die Hörkapsel 4 ist am Bügel in der Nähe des Gelenkes angebracht. Der Bügel befindet sich in Empfangsstellung, wobei das Mikrofon 5 am Helmrand anliegt. Der einen oder mehrere Kontakte aufweisende Sprechrichtungsumschalter ist im Gelenk für den Bügel 2 angeordnet und ist durch dessen Schwenkbewegungen betätigbar.The invention is explained in more detail with reference to the drawing. The drawing shows the execution of the in near the ear can be swiveled on the protective helmet hinged bracket with attached earpiece. The bracket 2 is pivotably attached to the protective helmet 1 by means of a joint 3. The earpiece 4 is on Bracket attached near the joint. The bracket is in the receiving position, with the Microphone 5 rests against the edge of the helmet. The speech direction switch having one or more contacts is arranged in the joint for the bracket 2 and can be actuated by its pivoting movements.
