Description
Meßlatte. Gegenstand der Erfindung ist eine Meßlatte für geodätische Meßgeräte (Nivelliergeräte, Tachymeter o. dgl.).Yardstick. The invention relates to a yardstick for geodetic Measuring devices (leveling devices, total stations, etc.).
Die bisher gebräuchlichen Meßlatten haben wagerechte Maßfelder oder Strichmarken. Nur vereinzelt finden sich Meßlatten mit schrägen Einteilungsfeldern. Bei diesen sind die Teilstriche der Einteilung nur wenig geneigt und an ihren Ableseflächen ohne Unterbrechung.The measuring rods that have been used up to now have horizontal measuring fields or Line marks. There are only a few measuring sticks with inclined graduation fields. With these, the graduation marks of the division are only slightly inclined and on their reading surfaces without interruption.
Die neue Erfindung besteht darin, daß das Maß der Steigung der Breite des Einteilungsfeldes genau entspricht, und daß die Einteilungsfelder durch lichte Striche in zueinander gleichen Abständen unterteilt sind.The new invention is that the measure of the slope of the width of the classification field corresponds exactly, and that the classification fields through clear Lines are divided at equal intervals.
Hieraus ergeben sich folgende Vorteile: Da die Steigung,der Meßfelder ihrer Breite entspricht, kann man an der schrägen Fläche, je nachdem, welchem lichten Striche der Meßfaden an der betreffenden Ablesekante des IvIeßfeldes am nächsten erscheint, Unterteile unmittelbar ablesen und weitere Unterteile schätzen.This results in the following advantages: Because the slope, the measuring fields corresponds to its width, you can clear the sloping surface, depending on which one Lines of the measuring thread next to the relevant reading edge of the measuring field appears, read the sub-parts immediately and estimate further sub-parts.
Trotz dieser bedeutenden Verfeinerung der Ablesemöglichkeit ist die Einteilung doch auch auf weiteren Entfernungen im Fernrohr noch gut zu erkennen. Die hohe Übersichtlichkeit schränkt Ablesefehler ein und macht dem Messenden die neue Art der Ablesung sofort verständlich.Despite this significant refinement of the reading option, the The division can still be seen well in the telescope even at further distances. The high level of clarity limits reading errors and makes the measuring operator the new way of reading immediately understandable.
Die Zeichnung zeigt die Erfindung in einer beispielsweisen Ausführungsform, und zwar: Abb. i für unmittelbare Ablesemöglichkeit von 2 mm, Abb. z für unmittelbare Ablesemöglichkeit von i mm.The drawing shows the invention in an exemplary embodiment, namely: Fig. i for direct reading of 2 mm, Fig. z for direct Possibility to read i mm.
Aus Abb. i ergibt sich, daß das Meßfeld a b d e um das Maß c d steigt, das gleich der Breite des Meßfeldes a b ist.From Fig. I it follows that the measuring field abde increases by the amount cd , which is equal to the width of the measuring field ab.
Bei Abb. i wird man Unterschiede von 0,5 mm, bei Abb. z solche von o,2 mm ohne weiteres schätzen können.In Fig. I there are differences of 0.5 mm, in Fig. Z, differences of o, 2 mm can easily estimate.
