KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Es gibt bereits Nasenstege für Klemmer, bei denen die sich an die Nase legenden
Korkstücke durch von Umbördelungen gebildete Gehäuse gehalten werden.
Das Wesen der vorliegenden Erfindung besteht darin, die kleinen Gehäuse c in der
Weise konisch zu gestalten, daß die Öffnung des Gehäuses am kleinsten ist und letzteres
sich nach innen zu erweitert. Der hierdurchThere are already nose bridges for Klemmer in which the pieces of cork that lie on the nose are held by housings formed by flanges.
The essence of the present invention is to make the small housings c conical in such a way that the opening of the housing is the smallest and the latter expands inward. The one through this
ίο erreichte Vorteil besteht einerseits darin, daß eine einfachere und zweckmäßigere Befestigung des Korkpolsters b möglich ist, indem dieses nur in das Gehäuse eingedrückt zu werden braucht und infolge der Elastizität des Korkes zuverlässig festsitzt und nicht mehr eingekittet werden muß, und andererseits darin, daß infolge der durch die konische Form des Gehäuses bedingten allseitigen Einschnürung in der Mitte des Korkpolsters die Sitzfläche desselben konvex herausgewölbt und durch diesen Umstand ein weicher und dabei doch sicherer Sitz erreicht wird.ίο achieved advantage is on the one hand that a simpler and more appropriate attachment of the cork pad b is possible by only needing to be pressed into the housing and due to the elasticity of the cork is reliably fixed and no longer needs to be cemented, and on the other hand that as a result Due to the constriction on all sides in the center of the cork cushion caused by the conical shape of the housing, the seat surface of the cork upholstery arches out convexly and through this circumstance a soft and yet secure fit is achieved.
In der beiliegenden Zeichnung ist die Erfindungsidee schematisch veranschaulicht.The idea of the invention is illustrated schematically in the accompanying drawing.
Die Wände des Gehäuses c laufen in der ersichtlichen Weise konisch zu. Die hierdurch bedingte allseitige Einschnürung des Korkpolsters b ist bei δ1 zu ersehen sowie die konvex herausgewölbte Sitzfläche bei ö2.The walls of the housing c are tapered in the manner that can be seen. The all-round constriction of the cork cushion b caused by this can be seen at δ 1 and the convexly arched seat surface at δ 2 .
