Description
Schutzbrille. Die bis jetzt gebräuchlichen Schutzbrillen haben zumeist den Nachteil, dass der Arbeiter auch bei kurzen Arbeits-Unterbrechungen die Brille abnehmen muss, falls er das Arbeits stück besichtigen will. Ferner tritt bei den jetzt gebräuchlichen Schutzbrillen mit Draht gestell, wie sie bei Autogenschweissern verwendet werden, infolge der ausströmenden Hitze eine starke Erhitzung des Drahtge stelles ein, wodurch unter Umständen Brand wunden auf der Stelle der Nase, an der die Brille aufsitzt, entstehen können. Ferner haben diese Brillen den Übelstand, dass stets nur genau dieselben Gläser verwendet wer den können.
Zerbricht ein Glas und ist ein genau passendes Glas nicht vorrätig, so ist die Brille wertlos. Durch die vorliegende Er findung werden die hier beschriebenen Übel stände der bisher gebräuchlichen Schutzbrille behoben.
In der Zeichnung ist eine beispielsweise Ausführungsform. der neuen Schutzbrille dar gestellt; es zeigt: Fig. 1 einen Aufriss, Fig. 2 ein Profil, Fig. 3 einen Grundriss. An dem ledernen Stirnband a sind die Bcfestigungsrieinen h der Brille angebracht. An diesem Stirnband c, sind zwei Führungs hülsen c ans Blech vorgesehen.
In den Füh rungshülsen gleiten .in vertikaler Richtung die Führungsstangen d, deren unbeabsichtigtes Verschieben durch in der Zeichnung weg gelassene Reibungsfedern verhindert wird. die man zwischen Hülse und Stange anbringen kann.
Die Führungsstangen c1 besitzen am unteren Ende je ein Gelenk e und tragen einen um diese Gelenke nach -oben ver- schwenkbaren, aus Stalildrahthergestellten, ge- meinsamen liahinen t: Derselbe bildet zwei federnde Schleifen, zwischen welchen die oberen Bänder der beiden Gläser g gefaht und mittelst je eines Klemmringes h fest geklemmt werden.
Wie aus der Abbildung ersichtlich ist, können bei dieser Brille Gläser verschiedener Grübe und Foriii (rund und oval) verwendet werden. Die Brille ruht gegenüber den bis- lierigen Ausführungsformen nicht auf der Nase, sondern wird mittelst des Stirnbandes an der Stirn befestigt. Verletzungen durch Brand wunden sind infolgedessen ausgeschlossen, da keine Metallteile mit der Haut in Be rührung kommen. Die verstellbaren Führungs stangen ermöglichen es, die Gläser in der richtigen Augenhöhe einzustellen.
Infolge der Anordnung der Gelenke kann die Brille durch einen einfachen Druck hochgeklappt und bei Ausbildung der Scharnierbolzen in den Gelenken e als Schrauben durch Anziehen der letzteren festgeklemmt werden, so dass der Arbeiter bei Arbeitsunterbrechungen nicht mehr die Brille abschnallen muss und trotz dem einen freien und unbehinderten Aus blick hat.
Safety goggles. The protective goggles in use up to now mostly have the disadvantage that the worker has to remove his glasses even during short work breaks if he wants to inspect the work piece. Furthermore, the wire frame now in use, as used by autogenous welders, causes excessive heating of the wire frame as a result of the escaping heat, which may cause burns on the part of the nose where the glasses are seated. Furthermore, these glasses have the disadvantage that only exactly the same glasses can be used.
If a glass breaks and a precisely fitting lens is not in stock, the glasses are worthless. With the present invention, the nuisances described here are corrected for the previously used protective goggles.
In the drawing is an example embodiment. the new safety glasses are presented; It shows: FIG. 1 an elevation, FIG. 2 a profile, FIG. 3 a plan view. The fastening straps h of the glasses are attached to the leather headband a. On this headband c, two guide sleeves c are provided on the sheet metal.
In the guide sleeves slide .in the vertical direction, the guide rods d, whose unintentional displacement is prevented by friction springs omitted in the drawing. which can be attached between the sleeve and the rod.
The guide rods c1 each have a joint e at the lower end and carry a joint liahine t made of Stalil wire, which can be swiveled upwards about these joints: it forms two resilient loops, between which the upper straps of the two glasses are drawn and be firmly clamped by means of a clamping ring h.
As can be seen from the illustration, glasses of various sizes and shapes (round and oval) can be used with these glasses. In contrast to the previous embodiments, the glasses do not rest on the nose, but are attached to the forehead by means of the headband. As a result, injuries from burns are ruled out as no metal parts come into contact with the skin. The adjustable guide rods make it possible to set the glasses at the correct eye level.
As a result of the arrangement of the joints, the glasses can be folded up by a simple push and, if the hinge bolts are formed in the joints e as screws, they can be clamped by tightening the latter, so that the worker no longer has to take off his glasses during work breaks and despite the one free and unimpeded Has out of sight.
