Optische Signaleinrichtung für Telekommunikationsgeräte, insbesondere TelefoneOptical signaling device for telecommunications equipment, in particular telephones
Die Erfindung betrifft eine optische Signaleinrichtung für Telekommunikationsgeräte, insbesondere Telefone in Form eines pulsierenden Blitzlichtes als zusätzliche Einrichtung zu einer akustischen Signaleinrichtung oder anstelle derer.The invention relates to an optical signaling device for telecommunications devices, in particular telephones in the form of a pulsating flash light as an additional device to an acoustic signaling device or instead of the latter.
Signaleinrichtungen dieser Art sind bekannt. Blink- oder Blitzsignale machen bspw. Hörgeschädigte auf Telefonanrufe aufmerksam. Optische Signaleinrichtungen werden aber auch dort zusätzlich zu akustischen Signaleinrichtungen vorgesehen, wo es darauf ankommt, daß wenigstens eines der Signale wahrgenommen wird, bspw. in lärmerfüllten Werkhallen oder im Freien, bspw.Signal devices of this type are well known. Blinking or flashing signals, for example, alert hearing-impaired people to telephone calls. Optical signal devices are also used in addition to acoustic signal devices where it is important that at least one of the signals is perceived, for example in noisy workshops or outdoors, for example.
auf Baustellen, Fabrikhöfen, Sportanlagen.on construction sites, factory yards, sports facilities.
Sofern die optische Signaleinrichtung mit einer lautstarken akustischen Signaleinrichtung zusammenwirkt, besteht häufig die Notvuendigkeit, daß mit Rücksicht auf die Umgebung die akustische Signaleinrichtung zu bestimmten Ruhezeiten, insbes.If the optical signalling device works together with a loud acoustic signalling device, it is often necessary, with regard to the environment, for the acoustic signalling device to be switched off at certain quiet times, in particular during the day.
nachts, nicht in Tätigkeit tritt. Üblicherweise sieht man deshalb von Hand zu betätigende Aus- bzw. Umschalter vor, ist aber dabei auf die menschliche Zuverlässigkeit angewiesen, damit die Schaltvorgänge auch wirklich durchgeführt werden.at night. For this reason, manual on/off switches are usually provided, but this relies on human reliability to ensure that the switching operations are actually carried out.
Mit der Erfindung wird nun vorgeschlagen, die optische Signaleinrichtung mit einem einstellbaren Dämmerungsschalter sowie mit einer Rufumschaltung zu kombinieren. Damit wirdThe invention now proposes combining the optical signaling device with an adjustable twilight switch and a call switch.
erreicht, daß, entsprechend der Einstellung des Dämmerungsschalters nur die optische Signaleinrichtung bei einem Anruf in Funktion tritt und durch den Rufumschalter dafür gesorgt wird, daß die optische Signaleinrichtung ausgeschaltet und der Anruf bspw. auf einen Anrufbeantworter oder auf einen anderen Telefonapparat umgeschaltet wird.This ensures that, depending on the setting of the twilight switch, only the optical signaling device is activated when a call is received and the call switch ensures that the optical signaling device is switched off and the call is switched, for example, to an answering machine or to another telephone.
Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird nachstehend kurz beschrieben. Es zeigenAn embodiment of the invention is shown in the drawing and is briefly described below. They show
Fig. 1 eine Draufsicht einer Aufputzausführung der optischen Signaleinrichtung für Außenanwendungen,Fig. 1 is a plan view of a surface-mounted version of the optical signaling device for outdoor applications,
Fig. 2 eine Seitenansicht der Fig. 1 undFig. 2 is a side view of Fig. 1 and
Fig. 3 eine Detailansicht der Fig. 1 bei geöffnetem Deckel des Anschlußteiles·Fig. 3 a detailed view of Fig. 1 with the cover of the connection part open
Die in den Fig. 1-3 dargestellte optische Signaleinrichtung 1 weist ein Gehäuse 2 auf, das im wesentlichen durch eine Streukappe 3 geschlossen ist, die die hier nicht im einzelnen dargestellten Einzelheiten, d.h. Blitzlampe, Dämmerungsschalter, Rufumschalter und Netzteil für die Blitzlichtuersorgung abdeckt. Der Teil des Gehäuses, der die Klemmen Ll und N für den Netzanschluß und die Klemmen Wb, W und Lb für den Telefonanschluß aufnimmt (s. Fig. 3) ist mit einem Deckel 4 versehen. Die Streukappe 3 besteht zweckmäßigerweise aus glasklarem Kunststoff, um eine hohe Lichtleistung der Signaleinrichtung zu gewährleisten.The optical signaling device 1 shown in Fig. 1-3 has a housing 2 which is essentially closed by a diffuser cap 3 which covers the details not shown here in detail, i.e. flash lamp, twilight switch, call switch and power supply for the flashlight supply. The part of the housing which accommodates the terminals Ll and N for the mains connection and the terminals Wb, W and Lb for the telephone connection (see Fig. 3) is provided with a cover 4. The diffuser cap 3 is expediently made of crystal-clear plastic in order to ensure a high light output of the signaling device.
