PATENTAMT.PATENT OFFICE.
Es ist schon vielfach versucht worden, die einzelnen Teile der Fassungen, namentlich die Stege an Brillen und Federn an Pincenez, auswechselbar zu machen. Nach vorliegender Erfindung wird die Aufgabe nun dadurch gelöst, daß der Steg oder die Feder in den Klammern oder Fassungen der Gläser durch Druckschrauben befestigt wird. Da diese Druckschrauben den Steg oder die Feder anMany attempts have already been made to find the individual parts of the versions, especially the To make bars on glasses and springs on Pincenez interchangeable. According to the present Invention, the object is now achieved in that the web or the spring in the Brackets or frames of the glasses are fastened by pressure screws. This one Pressure screw on the bar or the spring
ίο jeder beliebigen Stelle ihrer Länge festklemmen können, so ist der Steg oder die Feder nicht nur auswechselbar, sondern auch einstellbar, so daß auch mit demselben Steg oder derselben Feder ziemlich große Differenzen in der Pupillendistanz und Höhenlage ausgeglichen werden können. Diese genaue Einstellbarkeit ist namentlich wichtig für die modernen sogenannten Punktalgläser, weil bei diesen Gläsern bei geringer Exzentrizität gegenüber der Augenmitte der Vorzug der astigmatischen Korrektion verloren geht.ίο clamp at any point along its length can, the bar or the spring is not only exchangeable, but also adjustable, so that even with the same bridge or the same nib, there are quite large differences in the pupillary distance and altitude can be compensated. This exact adjustability is especially important for the modern so-called Punktal glasses, because these glasses have little eccentricity the center of the eye loses the advantage of astigmatic correction.
In der Zeichnung ist in Fig. 1 ein Pincenez dieser Art in der Ansicht dargestellt. Fig. 2 zeigt in vergrößertem Maßstabe einen Schnitt durch die Fassung, Fig. 3 ebenfalls in vergrößertem Maßstabe einen Querschnitt durch die Fassung und ein Glas, der rechtwinklig zum Querschnitt der Fig. 2 liegt.In the drawing, a Pincenez of this type is shown in Fig. 1 in the view. Fig. 2 shows on an enlarged scale a section through the socket, FIG. 3 also on an enlarged scale Scale a cross-section through the socket and a glass that is rectangular to the cross section of FIG.
Die Gläser g sind mit Glasklammern k versehen, welche an Verlängerungen die Stege s tragen. Die Feder f, oder bei Brillen der Nasensteg, erhält zweckmäßig rechteckigen Querschnitt (Fig. 3) und wird in den beiden Klammern k durch eine oder zwei Druckschrauben d befestigt (Fig. 2 und 3). Die Druckschrauben d erhalten zweckmäßig Körnerspitzen, die sich beim Anziehen in die Feder f hineindrücken (Fig. 3).The glasses g are provided with glass clips k which carry the webs s on extensions. The spring f, or the nose bridge in the case of glasses, is appropriately rectangular in cross section (FIG. 3) and is fastened in the two brackets k by one or two pressure screws d (FIGS. 2 and 3). The pressure screws d are expediently given center points which, when tightened, press into the spring f (FIG. 3).
