Abstract

A pair of goggles against dazzling by the sun and snow is proposed which enable the wearer of the goggles to have the incident light beams individually filtered out. By means of two polarisation films arranged one behind another in the eye pieces, one polarisation film being functionally connected in each case in a rotary fashion to a centrally arranged wheel, the polarising grids of the polarisation films are more or less superimposed by rotating the wheel, so that in use the absorption can be regulated by the wearer of the goggles.

Description

'Beschreibung'Description

Die Erfindung betrifft eine Schutzbrille, wie diese gegen Sonnen- und Schneeblendung Verwendung binden soll. Es sind bereits die verschiedensten Au3führungsformen bekannt, die sich durch ihre Formgebung und Farbtönung der Glaser unterscheiden.The invention relates to protective goggles such as these against Is intended to bind sun and snow glare use. There are already the most diverse forms of implementation known, which differ in their shape and color of the glasses.

Phototrope Brillengläser, die je nac'~ Lichtstärke selbsttätig Lichtstrahlen wegfiltern, haben ren grossen Nachteil, dass sie nicht individuell regulierbar sind. An diesem Punkt setzt die Erfindung ein. Es wird eine Schutzbrille vorgeschlagen, die es dem Träger ermöglicht, stufenlos die Okulare auf eine helle oder dunklere Farbtönung einzustellen. Im einzelnen besteht die Erfindung darin, dass jedes Okular aus zwei hintereinander angeordneten Polarisationsfolie'n 1,1a und 2,2a besteht, wobei die Polarisationsfolien 1 und 2 fest- und die Polarisationsfolien 1a und 2h drehbar- im Brillengestell oder Brillenvorhänger gelagert sind.Photochromic spectacle lenses, which automatically filter out light rays depending on the light intensity, have the major disadvantage that they cannot be individually regulated. This is where the invention begins. Protective goggles are proposed which enable the wearer to continuously adjust the eyepieces to a light or dark shade. In detail, the invention consists in that each eyepiece consists of two consecutive polarization foils 1,1a and 2,2a, the polarizing foils 1 and 2 being fixed and the polarizing foils 1a and 2h rotatably mounted in the glasses frame or glasses hangers.

Durch Drehen des Rändelrades 3 überlagern sich die Polgitter der Polarisationsfolien mer oder weniger, so dass im Gebrauch die einfallenden Lichtstrahlen regulierbar weggefiltert werden.By turning the knurled wheel 3, the polar grids of the polarization films are superimposed more or less, so that In use, the incident light rays can be filtered away in an adjustable manner.

Anhand der Abbildungen wird die Erfindung im einzelnen näher erläutert:The invention is explained in more detail using the figures:

Figur 1 zeigt die Vorderansicht der beschriebenen Schutzbrille. Ein Rändelrad 3 greift formschlüssig in die Rändelungder im Brillengestell 4 drehbar gelagerten Polarisationsfolienia und 2a ein und decken die mit dem Brillengestell 4- festverbundenen Polarisation·;-folien 1 und 2 ab.Figure 1 shows the front view of the protective goggles described. A knurled wheel 3 engages positively into the knurling of the polarizing films rotatably mounted in the spectacle frame 4 and 2a and cover the polarization films that are firmly connected to the spectacle frame 4 1 and 2.

Figur 2 stellt den Horizontalschnitt A-A undFigure 2 shows the horizontal section A-A and

Figu 3 den dazugehörigen Vertikalschnitt B-B dar.Figu 3 shows the associated vertical section B-B.
