Description

  

  Zeichengerät     zum    Zeichnen von     Kreisbogen       Die Erfindung     betrifft    ein Zeichengerät     zum    Zeich  nen von insbesondere sehr grossen     Kreisbögen.     



  Nach bisheriger Methode konnten grosse     Kreise    und       Kreisbögen    nur mit grossem Arbeitsaufwand hergestellt  werden.  



  Zweck der Erfindung ist, den aufgeführten Nachteil  zu beheben.  



  Bei dem     erfindungsgemässen    Zeichengerät sind min  destens     zwei    Räder     mit    verschiedenem Durchmesser vor  gesehen, welche durch eine Achse     miteinander    verbun  den sind und auf dieser in ihrem     Spurabstand        verstellbar     sind.  



  Im folgenden ist ein     Ausführungsbeispiel    des Erfin  dungsgegenstandes anhand einer dasselbe darstellenden  Zeichnung näher erläutert.  



  Im Hauptstück (1), auf welchem der Griff (2) mon  tiert ist, ist die Achse (3) gelagert, auf welcher das  kleinere Funktionsrad (4) befestigt ist. Auf der Achse    (3) befindet sich die verschiebbare Hülse (5), welche im  Schlitten (6) gelagert ist, der durch die Gewindespindel  (7) hin- und herbewegt wird. Auf der Hülse (5) ist das  grössere Funktionsrad (8) befestigt. Die Gewindespindel  (7) ist gelagert im Zylinder (9) und verbunden mit der       Einstellhülse    (10). Auf dem Hauptstück (1) ist noch die  Führung (11) befestigt, in welcher der     Zeichenstifthal-          ter    (12) läuft, sowie das     Auflagerad    (13).



  Drawing device for drawing circular arcs The invention relates to a drawing device for drawing particularly large circular arcs.



  According to the previous method, large circles and arcs could only be produced with great effort.



  The purpose of the invention is to remedy the disadvantage mentioned.



  In the drawing device according to the invention, at least two wheels with different diameters are seen, which are connected to one another by an axis and are adjustable in their track spacing on this.



  In the following an embodiment of the invention is explained in more detail with reference to a drawing showing the same.



  In the main piece (1), on which the handle (2) is mounted on it, the axis (3) is mounted on which the smaller function wheel (4) is attached. The displaceable sleeve (5) is located on the axis (3) and is mounted in the slide (6) which is moved back and forth by the threaded spindle (7). The larger function wheel (8) is attached to the sleeve (5). The threaded spindle (7) is mounted in the cylinder (9) and connected to the adjusting sleeve (10). The guide (11), in which the pen holder (12) runs, and the support wheel (13) are attached to the main piece (1).
