  Reissbrett. 



   Bei Benützung eines Reissbrettes, welches der Grösse des Zeichenblattes angepasst ist, ergeben sich leicht Schwierigkeiten, sobald für die   Konstruktion ausserhalb   des Zeichenblattes gelegene Punkte, beispielsweise Fluchtpunkte oder Kreismittelpunkte, in Verwendung kommen sollen. Durch die Erfindung wird dieser   Ubelstand   beseitigt. Sie besteht im wesentlichen darin, dass am Reissbrett herausziehbar Schienen vorgesehen sind, welche im Bedarfsfalle über die Kanten des Brettes hinaus verschoben werden können, so dass auf ihnen die für die Darstellung etwa notwendigen Hilfspunkte verzeichnet werden können. 



   Die Zeichnung veranschaulicht ein Ausführungsbeispiel des Erfindungsgegenstandes, und zwar zeigt Fig. 1 eine Draufsicht, Fig. 2 einen Querschnitt. 



   In der Längsachse des Reissbrettes a sind zwei Schienen b angeordnet, die in Schwalben-   Hchwanzführungen   verschiebbar sind und nur derartige Dicke besitzen, dass sie auch in der Gebrauchsstellung bl das Anlegen der Reissschiene nicht behindern. Es ist selbstverständlich auch möglich, zu der Schiene b senkrechte Schienen anzubringen sowie das Querholz c der Schienen der Breite des Brettes gleich zu machen.

  Drawing board.



   When using a drawing board which is adapted to the size of the drawing sheet, difficulties easily arise as soon as points located outside the drawing sheet, for example vanishing points or circle centers, are to be used for the construction. This disadvantage is eliminated by the invention. It essentially consists in the fact that pull-out rails are provided on the drawing board, which, if necessary, can be shifted beyond the edges of the board so that the auxiliary points that may be necessary for the representation can be recorded on them.



   The drawing illustrates an exemplary embodiment of the subject matter of the invention, namely FIG. 1 shows a plan view, FIG. 2 shows a cross section.



   In the longitudinal axis of the drawing board a two rails b are arranged, which can be displaced in dovetail guides and are only thick enough that they do not hinder the application of the drawing rail even in the position of use b1. It is of course also possible to attach rails perpendicular to the rail b and to make the crossbar c of the rails equal to the width of the board.
