Abstract
Description
Die Erfindung betrifft eine Vorrichtung entsprechend dem Ober begriff des Anspruchs 1.The invention relates to a device according to the waiter Concept of claim 1.
Mit einem Zirkel ist es möglich, Kreisbögen mit einem exakten Radius zu zeichnen. Die wechselnden Radien müssen von einem Meßstab abgenommen werden.With a compass it is possible to create arcs with an exact Draw radius. The changing radii must be one Dipstick can be removed.
Dies ist umständlich und führt leicht zu fehlerhafter Ablesung.This is cumbersome and easily leads to incorrect reading.
Die Aufgabe meiner Erfindung ist es, die Messung in den Zirkel zu integrieren und damit die Arbeit mit dem Zirkel wesentlich zu vereinfachen.The object of my invention is the measurement in the circle to integrate and thus work with the circle essential to simplify.
Diese Aufgabe wird durch eine Vorrichtung mit den Merkmalen des Anspruchs 1 gelöst.This object is achieved by a device with the features of Claim 1 solved.
Durch die Integration der Meßvorrichtung, erübrigt es sich einem separaten Meßstab mitzuführen. Die Einstellung auf einen bestimmten Radius ist einfacher und die Ablesung übersichtli cher.The integration of the measuring device makes it unnecessary carry a separate dipstick. Attitude to one certain radius is easier and the reading is clear cher.
Selbst eine Angabe durch Digitalanzeige wäre denkbar. Even an indication by digital display would be conceivable.
Ausführungsbeispiele der Erfindung sind in den Zeichnungen (Abb. 1) dargestellt und werden im Folgenden näher beschrieben.Embodiments of the invention are shown in the drawings ( Fig. 1) and are described in more detail below.
Die Abbildung zeigt die Vorderansicht des Zirkels mit inte grierter Meßvorrichtung.The picture shows the front view of the compass with inte grated measuring device.
Im unteren Teil der Zirkelbeine, bei , gegeneinanderlaufende, geeichte Meßschienen angebracht. Sie werden jeweils am gegen überliegenden Zirkelbein durch Ösen geführt. Die Ablesungen der Radien erfolgen ähnlich wie wie bei einer Schieblehre.In the lower part of the compass legs, at, opposing, calibrated measuring rails attached. You will be on the opposite overlying compass leg through eyelets. The readings the radii are similar to those of a caliper.
Es zeigt sich, daß durch die zwei angebrachten Teile die ein gestellte Weite der Zirkelspitzen aufgrund des Strahlensatzes genau angegeben werden kann.It turns out that by the two parts attached the one the width of the compass points based on the radiation set can be specified exactly.
Die Berechnung der Teilstriche des Meßstabes ergibt sich aus dem Strahlensatz (Vergleiche Abb. 2).The calculation of the graduations of the dipstick results from the radiation set (see Fig. 2).
Die Länge a auf dem Meßstab errechnet sich aus dem Abstand der Zirkelspitzen mit.The length a on the dipstick is calculated from the distance between the Compass tips with.
