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.
