Description

Brillenohrbüge1 mit Golddoublegespinstumwicklung Die Erfindung bezieht sich auf Brillenohrbügel mit Golddoublegespinstumwicklung. Der Erfindungsgedanke besteht darin, für die Golddoublegespinstumwicklung einen Golddoublegespinstdraht zu verwenden, der mit einer ungleichmäßig starken Goldlegierungsummantelung versehen ist, und zwar ist die Anordnung so getroffen, daß der Golddoublelegierungsmantel an der Ohrbügelaußenseite eine stärkere Materialanhäufung aufweist als innen. Auf diese Weise wird erreicht, daß man mit einer bestimmten Menge von Golddouble eine sehr viel widerstandsfähigere Beschaffenheit des Brillenohrbügels erzielt als bisher, da ja die beanspruchte außenliegende Goldlegierungsmaterialmenge infolge ihrer starken Anhäufung einer äußerst starken Abnutzung gewachsen ist. Die Erhöhung der Lebensdauer wird ohne Erhöhung des Feingoldgehaltes erreicht.Eyeglass ear bows1 with gold double-spun wrapping The invention relates to on eyeglass earhooks with gold double thread wrapping. The idea of the invention consists of using a double-twisted gold wire for the double-twisted gold wrapping to use, which is provided with an unevenly thick gold alloy coating is, namely the arrangement is made so that the gold double alloy jacket has a greater accumulation of material on the outside of the ear hook than on the inside. on in this way it is achieved that with a certain amount of gold double one Much more resistant quality of the eyeglass ear hook achieved than before, because of the stressed external amount of gold alloy material due to its strong Accumulation has grown to an extremely heavy wear. Increasing the service life is achieved without increasing the fine gold content.

Wenn in der vorstehenden Beschreibung von einer Goldlegierungsummantelung oder von einer Golddoublegespinstumwicklung gesprochen wird, so soll dadurch keine Beschränkung auf ein bestimmtes Material ausgesprochen sein, sondern dieser Ausdruck ist nur gewählt worden, weil ein derartiges Material in der Brillenohrbügelherstellung das übliche darstellt. Im Rahmen der Erfindung liegt selbstverständlich auch die Verwendung von Goldgespinst oder einem aus einem anderen Edelmetall bestehenden Gespinst, vorausgesetzt, daß der Gold- oder Edelmetallmantel an der Ohrbügelaußenfläche eine stärkere Materialanhäufung aufweist als innen.If in the above description of a gold alloy coating or if there is talk of a gold double thread winding, it is not intended to result in any Restriction to a specific material, but this expression has only been chosen because such a material is used in the manufacture of eyeglass ear hooks represents the usual. In the context of the invention, of course, is also the Use of spun gold or one made from another precious metal Web, provided that the gold or precious metal jacket is on the outer surface of the ear hook has a greater accumulation of material than inside.
