Description

Schutzbrille für Kraftfahrer. Die.Erfindung betrifft eine Schutzbrille für Kraftfahrer. Sie besteht darin, daß in geeigneter Entfernung hinter den Brillengläsern je eine elektrische, von Strom beliebiger Herkunft gespeiste Heizvorrichtung vorgesehen ist, die bei kaltem Wetter durch Erwärmung der Gläser ein Beschlagen. derselben vermeidet.Safety glasses for motorists. The invention relates to protective goggles for drivers. It consists in being at a suitable distance behind the glasses an electric heating device fed by electricity of any origin is provided is that in cold weather by heating the glasses a fogging. the same avoids.

Der Gegenstand der Erfindung ist in der Zeichnung in einer Ausführungsform beispielsweise veranschaulicht; es stellt dar Abb. i eine im Erfindü@ngssinn ausgebildete Brille in -der Vorderansicht, teilweise im Schnitt, und Abb.2 eine solche .im Grund'riß, teilweise im Schnitt.The object of the invention is shown in the drawing in one embodiment for example illustrated; it represents Fig. i a trained in the sense of the invention Glasses in the front view, partly in section, and Fig. 2 such a plan, partly in cut.

In geeigneter Entfernung hinter den Brillengläsern tr, also auf deren Innenseite, ist je eine der Form dier Brille angepaßte Heizvorrichtung U vorgesehen. Die elektrischen Widerstände der Heizkörper sind hierbei derart .hintereinander geschaltet, -daß Anfang und Ende desselben an einer Seite der Brille liegen. Die Einrichtung kann naturgemäß auch so getroffen sein, -d'aß die beiden Widerstände parallel geschaltet sind. Als Stromquelle für die Heizvorrichtung kann entweder eine Akkumulatorenba@tterie oder auch 'bei Nacht die Lichtmaschine des, Kraftfahrzeuges selbst dienen. Durch einen .in, die Zuleitung eingeschalteten Reglungswiderstand kann .die Temperatur der Heizvorrichtung entsprechend eingestellt werden. Es ist unter Umständen sehr zweckmäßig, die Heizkörper herausnehmbar anzuordnen, so,daß die Schutzbrille während der warmen Jahreszeit ohne Heizkörper verwendet werden kann. Die Art der Isolation des Heizkörpers kann beliebig sein und bildet nicht den Gegenstand der vorliegenden Erfindung. Ebenfalls kann die Form der Widerstände eine andere als die dargestellte ein.At a suitable distance behind the glasses tr, so on their Inside, a heater U adapted to the shape of the glasses is provided. The electrical resistances of the radiators are here one behind the other switched, -that the beginning and end of the same are on one side of the glasses. the The device can of course also be designed in such a way that the two resistors are connected in parallel. As a power source for the heating device can either an accumulator battery or, at night, the alternator of the motor vehicle serve yourself. By a control resistor switched on in the supply line the temperature of the heater can be adjusted accordingly. It is may be very useful to arrange the radiators removable so that the protective goggles can be used without a radiator during the warm season can. The type of insulation of the radiator can be any and does not form the subject of the present invention. Likewise, the shape of the resistors any other than the one shown.
