Description

Wasserwaage mit im Dunkeln sichtbar gemachten Libellen Wasserwaat,en mit im Dunkeln sichtbar gemachten Libellen sind bekannt, z. B. durch Einsetzen von durch Taschenlampenbatterien gespeiste Glühbirnen. Ferner ist bekannt, bei Libellen durch Auftragen von Leuchtfarble auf den Libellenrand die Luftblase sichtbar zu machen. Die Erfindung zieht sich auf eine Wasserwaage, bei der die Libelle in eine durchgehende Bohrung eingesetzt ist.Spirit level with dragonflies made visible in the dark with dragonflies made visible in the dark are known, e.g. B. by inserting lightbulbs powered by flashlight batteries. It is also known in dragonflies by applying luminous paint to the edge of the dragonfly, the air bubble becomes visible do. The invention applies to a spirit level in which the dragonfly is in a through hole is used.

In den inneren Teil der durchgehenden Bohrungen, in denen die Waageliblellen liegen, wird erfindungsgemäß Leuchtfarhe aufgetragen; dadurch wird das Luftbläschen in der Waagelibelle sichtbar. In the inner part of the through holes in which the level vials are, according to the invention, luminous paint is applied; this causes the air bubble visible in the vial.
