Description
Globus Es sind bereits Einrichtungen an Globen bekannt, die es gestatten, die Entfernung zweier Erdpunkte zu bestimmen. Aber die Bestimmung des zweiten Merkmals, der Wegrichtung im Ausgangspunkt der Messung, fehlt. Die im folgenden beschriebene Einrichtung ermöglicht, durch einfache Handgriffe in bekannter Weise nicht nur den kürzesten Weg zwischen zwei Erdpunkten festzulegen und zu messen, sondern auch gleichzeitig die Wegrichtung im Ausgangspunkt der Messung zu bestimmen.Globus Devices are already known on globes which allow determine the distance between two earth points. But the determination of the second characteristic, the direction of the path in the starting point of the measurement is missing. The one described below Facility made possible by simple manipulations in a known manner not only the Determine and measure the shortest path between two earth points, but also at the same time determine the direction of travel at the starting point of the measurement.
Die bekannten Einrichtungen bestehen aus einem um seine Achse drehbaren Globus mit einem Meridiankreisring, auf dem der Drehpunkt eines klappbaren Vollkreisringes verschiebbar angeordnet ist. Durch Drehung des Globus und Verschieben des Drehpunktes läßt sich der eine der beiden gewählten Erdpunkte unter den Drehpunkt bringen. Wird nunmehr der Vollkreisring so weit umgeklappt, daß er den zweiten Erdpunkt berührt, so zeichnet derselbe den kürzesten Verbindungsweg zwischen den beiden Erdpunkten auf dem Globus ab, dessen. Länge auf der auf dem Vollkreisring angebrachten, am Drehpunkt mit o beginnenden Maßskala ablesbar ist. Die Erfindung besteht nun gegenüber dieser bekannten Anordnung darin, daß zur Richtungsbestimmung der Vollkreisring mit einer Meßeinrichtung fest gekuppelt ist, die den Winkel zwischen der Vollkreisebene und der' Meridianebene, also der Nord-Süd-Richtung; ablesbar macht.The known devices consist of a rotatable about its axis Globe with a meridian circular ring on which the pivot point of a foldable full circular ring is arranged displaceably. By rotating the globe and moving the pivot point one of the two selected earth points can be brought under the pivot point. Will now the full circular ring folded so far that it touches the second earth point, so it draws the shortest connection path between the two earth points on the globe, whose. Length on the attached to the full circular ring, on The pivot point can be read off with a scale beginning with o. The invention now exists against this known arrangement is that to determine the direction of the full circular ring is firmly coupled to a measuring device that determines the angle between the full circle plane and the 'meridian plane, i.e. the north-south direction; makes readable.
In der Zeichnung ist eine Ausführung beispielsweise dargestellt. Mit dem Vollkreisring 2 wird seine Drehachse 3 und mit dieser ein in der Vollkreisebene liegender Zeiger 4 fest verbunden. Dieser spielt beim Klappen des Vollkreises 2 auf einer mit einer Kreisteilung versehenen Skala 5, die an der Lagerung der Drehachse befestigt ist und damit in ihrer Lage zum Meridiankreisring i, also der Nord-Süd-Richtung, festgehalten ist.One embodiment is shown in the drawing, for example. With the full circular ring 2 is its axis of rotation 3 and with this one in the full circular plane horizontal pointer 4 firmly connected. This plays when folding the full circle 2 on a graduated scale 5, which is attached to the bearing of the axis of rotation is attached and thus in its position to the meridian annulus i, i.e. the north-south direction, is held.
