Description

  

  Zeichenvorrichtung.    Um beim technischen Zeichnen das Reiss  brett in steiler Stellung benützen zu können,  ist eine Vorrichtung erforderlich, die die  Reissschiene in jeder Lage am Reissbrett fest  hält. Bei den bekannten     Reissschienenführun-          gen    finden hierzu am Reissbrett angebrachte  Rollen in Verbindung mit Schnüren oder  Ketten Verwendung, an denen die Reiss  schiene     befestigt    ist.  



  Nach der vorliegenden Erfindung wird  diese Aufgabe dadurch gelöst, dass die Zei  chengeräte derart ausgebildet sind,     da.ss    sie  untereinander durch magnetische Kräfte  festgehalten werden.  



  In der     Abb.    1 ist eine beispielsweise Aus  führungsform des     Erfindungsgegensk-indes     dargestellt. Das Reissbrett a ist an der     An-          chlagseite    mit einer Eisenleiste b versehen.  Der     Reissschienenkopf    trägt einen Magnet c  oder ist selber als Magnet ausgebildet.  Dieser haftet durch seine magnetische Kraft  an der Eisenschiene b. Auf dem     Reissschie-          nenblatt    d kann in bekannter Weise ein  Winkel e     aufgelegt    werden.  



  In     Abb.    2 ist in beispielsweiser Aus  führung dargestellt, wie ein mit Magnet ver-         sehener    Winkelf oder ein mit Magnet     ver-          sehener    Massstab     g    oder ein selbst als Magnet  wirkender Winkel     lt    an der Reissschiene fest  gehalten wird. Das     Reissschienenblatt    d russ  zu diesem Zweck an mindestens einer Kante       magnetisch        anziehbares    Material i aufweisen.



  Drawing device. In order to be able to use the drawing board in an upright position during technical drawing, a device is required that holds the drawing bar firmly in every position on the drawing board. In the known drawing rail guides, rollers attached to the drawing board are used in conjunction with cords or chains to which the drawing rail is attached.



  According to the present invention, this object is achieved in that the drawing devices are designed in such a way that they are held together by magnetic forces.



  In Fig. 1, an example of an embodiment of the invention is shown. The drawing board a is provided with an iron strip b on the stop side. The tear rail head carries a magnet c or is itself designed as a magnet. Due to its magnetic force, it sticks to the iron rail b. An angle e can be placed on the tear rail sheet d in a known manner.



  Fig. 2 shows an example of how an elbow provided with a magnet or a scale g provided with a magnet or an angle lt, which itself acts as a magnet, is held firmly on the tear bar. For this purpose, the tear rail sheet d russ have magnetically attractable material i on at least one edge.
