Description
Schutzbrille für Kraftfahrer. Durch das deutsche Patent 373865 ist eine Schutzbrille für Kraftfahrer bekannt geworden, bei welcher die Gläser durch eine elektrische Heizvorrichtung erwärmt und so vor dem Beschlagen geschützt werden. Die Heizvorrichtung ist in einem Abstand hinter den Gläsern vorgesehen.Safety glasses for drivers. The German patent 373865 has disclosed protective goggles for motorists in which the glasses are heated by an electrical heating device and are thus protected from fogging. The heating device is provided at a distance behind the glasses.
Der Gegenstand der Erfindung ist dadurch verbessert worden, daß die elektrische Heizvorrichtung auf der Innenseite der Brillengläser diesen unmittelbar anliegt. Die Widerstandsdrähte sind an der dem Auge zugekehrten Seite von einer Isolierung aus Porzellan oder einer anderen geeigneten Masse umgeben, welche zu beiden Seiten des Drahtes ebenfalls am Brillenglas anliegt, so daß fast ausschließlich eine Erwärmung des Glases stattfindet.The object of the invention has been improved in that the electrical heating device on the inside of the lenses this directly is present. The resistance wires are on the side facing the eye from one Insulation made of porcelain or some other suitable mass surrounding which to both sides of the wire also rests against the lens, so that almost exclusively the glass is heated.
Um die Herstellung der Isolierung zu vereinfachen, kann unmittelbar hintcr dem Draht in bekannter Weise auch ein zweites Brillenglas angeordnet werden, so daß die Isolierung nur am Rande zwischen den beiden Gläsern zu erfolgen braucht.In order to simplify the production of the insulation, directly a second spectacle lens can also be arranged behind the wire in a known manner, so that the insulation only needs to be done at the edge between the two glasses.
Der Erfindungsgegenstand ist auf der Zeichnung beispielsweise dargestellt, und zwar zeigt: Abb. i eine Vorderansicht, Abb. 2 einen Längsschnitt im Grundriß, wobei die Drähte dem Auge gegenüber von einer Isolierung umgeben sind, Abb. 3 einen gleichen Längsschnitt, wobei hinter dem Draht ein zweites Brillenglas angebracht ist.The subject of the invention is shown in the drawing, for example, namely shows: Fig. i a front view, Fig. 2 a longitudinal section in plan, the wires are surrounded by insulation opposite the eye, Fig. 3 a same longitudinal section, with a second lens attached behind the wire is.
Unmittelbar hinter dem Brillenglas i liegt der Widerstandsdraht 2 eng an und ist an seinen freien Seiten, insbesondere dem Auge gegenüber, mit einer Isolierung3 aus beliebigem Material umgeben, so daß fast ausschließlich eine Erwärmung nur des Glases stattfindet. Dadurch wird ein Beschlagen der Gläser durch Temperatur- oder Witterungseinflüsse wirksamer verhindert, als wenn die Heizvorrichtung in einem Abstand hinter den Brillengläsern angeordnet ist.The resistance wire 2 is located directly behind the spectacle lens i closely and is on its free sides, especially opposite the eye, with a Insulation3 made of any material, so that almost exclusively heating only of the glass takes place. This prevents the glasses from fogging up due to temperature or weather influences more effectively prevented than if the heating device in a Distance is arranged behind the lenses.
Zwecks vereinfachter Herstellung der Isolierung kann hinter dem Draht auch ein zweites Brillenglas q. vorgesehen sein.In order to simplify production of the insulation can be behind the wire also a second lens q. be provided.
