Description
Die Erfindung betrifft eine neue Konstruktion eines Fernsprechapparats, bei der die Gabelfür den Umschalter fortfällt.The invention relates to a new construction of a telephone set, in which the fork for the switch is omitted.
Die bisher üblichen Gabelumschalterkonstruktionen haben folgende Nachteile: leichte Zerstörbarkeit, Störanfälligkeit durch Klemmen, die Möglichkeit, mit der Gabel Wählimpulse zu gelben, unnötige Belastung der Zentralorgane durch wiederholtes Drücken auf die Gabel und kurzfristiges Neuwähler beim Besetztsein eines Anschlusses, während der Hörer am Ohr behalten wird.The previously common hook switch designs have the following disadvantages: easy destructibility, susceptibility to failure due to jamming, the possibility of using the Fork dialing impulses to yellow, unnecessary stress on the central organs by repeated Pressing the fork and short-term redial when a line is busy, while holding the handset to the ear.
Diese den -bekannten .Fernsprechapparaten anhaftenden Nachteile werden gemäß der Erfindung dadurch vermieden, daß die durch Abheben des Hörers zu betätigenden iSchalter magnetisch ausgelöst werden. Die Abbildung zeigt einen Ausschnitt aus dem Fernsprechapparat gemäß der Erfindung. Die Gehäusekappe des .Fernsprechapparats a, a soll nach außen hin völlig geschlossen und ohne Durchführung sein. In der Gehäusewand fest eingegossen sind zwei Dauermagnete d, d. Außen liegt auf dem Gehäuse der Hörer b auf. In diesem Hörer b ist, wie es an der Bruchstelle dargestellt ist, ein Weicheisenstück e eingegossen, das mit den beiden Schenkeln der Dauermagneten d, d, die in einem gewissen Abstand c voneinander eingegossen sind, einen Hufeisenmagnet bildet, wenn der Hörer aufliegt. Das Feld ist dann so stark, daß ein Weicheisenanker h, der fest mit einer Kontaktfeder f verbunden ist, an-` gezogen wird. Dadurch werden die Kontakte i des Kontaktfederpaketes g geöffnet und der Strom wird unterbrochen. Wird umgekehrt der Hörer abgenommen, so wird das Weicheisenstück e, das fest am Hörer sitzt, mit diesem entfernt. Der :Kraftlinienfluß des Magneten wird hierdurch so stark geschwächt, daß der Anker lt nicht mehr gehalten wird und abfällt. Er drückt dabei die Feder f herunter, wodurch die Kontakte i @geschlossen werden.These disadvantages inherent in the known telephones are avoided according to the invention in that the iSwitches to be actuated by lifting the handset are triggered magnetically. The figure shows a section of the telephone set according to the invention. The housing cap of the .Fernsprechapparats a, a should be completely closed to the outside and without implementation. Two permanent magnets d, d. The receiver b rests on the outside of the housing. In this receiver b, as shown at the break point, a piece of soft iron e is cast, which forms a horseshoe magnet with the two legs of the permanent magnets d, d, which are cast at a certain distance c from each other, when the receiver rests. The field is then so strong that a soft iron anchor h, which is firmly connected to a contact spring f, is attracted. As a result, the contacts i of the contact spring assembly g are opened and the current is interrupted. Conversely, if the receiver is picked up, the piece of soft iron e, which is firmly attached to the receiver, is removed with it. The: Kraftlinienfluß of the magnet is thereby attenuated so much that the armature lt no longer is maintained and falls. He presses down the spring f , whereby the contacts i @ are closed.
