Description
Verfahren zum Befestigen randloser Augengläser an der Metallgarnitur. Bei dem Befestigen von Augengläsern ohne Rand an der Metallgarnitur zeigt sich der Ubelstand, d@aß sich bei längerem Gebrauche die Verbindung zwischen Glas und Metallklammer lockert;,dies wird verständlich, wenn man bedenkt, daß die Klammer, die das Glas hält, nur aus sehr dünnem Metall besteht und daher der Schraube wenig Halt bietet (Fig. i). Man hat deshalb, schon den Weg beschritten, das Loch im Glase durch Packungen aller Art auszufüllen, auch durch Metallpackungen, die indes in den meisten Fällen keine innige Verbindung mit dem Glase hatten, sondern mehr den Zweck verfolgten, das Glasloch auszufüllen und dadurch den beiden Klammerbacken eine sichere Auflage zu bieten.Method of attaching rimless eyeglasses to the metal fitting. When attaching eyeglasses without a rim to the metal fittings, the Bad condition, that the connection between the glass and the metal clamp ate with prolonged use loosens; this becomes understandable when you consider the brace that holds the glass holds, consists only of very thin metal and therefore offers little hold to the screw (Fig. I). That is why one has already walked the path through packing the hole in the glass to be filled in of all kinds, including through metal packs, but in most cases had no intimate connection with the glass, but rather pursued the purpose, to fill the glass hole and thereby a secure support for the two clamping jaws to offer.
Die Erfindung verwendet gleichfalls eine Metallpackung im Loch des Glases, aber eine s s olche, die mit dem Glase in inniger, fester Verbindung steht. Um diesen Zweck zu erreichen, wird ein Verfahren angewendet, das in der Verglasungstechnik bereits benutzt wird. Die Ränder des Loches werden mit einer leitenden Schicht überzogen und diese in einer Metallsalzlösung unter Strom gesetzt; es. bildet sich dann bei längerer Dauer ein Metallniederschlag, der schließlich das ganze Loch ausfüllt.The invention also uses a metal packing in the hole of the Glass, but one that is closely and firmly connected with the glass. To achieve this purpose, a method is used that is known in glazing technology is already in use. The edges of the hole are covered with a conductive layer and electrified it in a metal salt solution; it. then forms at a metal precipitate which eventually fills the whole hole.
Ist auf diese Weise eine fest mit dem Glase verbundene Metalleinlage, gewissermaßen ein doppelköpfiger Niet (Fig.2), eingefügt, so läßt sich das Glas in bekannter Art durch Schrauben oder Löten sicher an der Metallgarnitur befestigen.If a metal insert is firmly attached to the glass in this way, as it were a double-headed rivet (Fig.2), inserted, so the glass Fasten securely to the metal fittings in a known manner by screwing or soldering.
