Description
Die Bauentwurfslehre von Prof. E. Neufert besagt auf S. 21: »Keine Maßlatten mit verschiedenen Maßstäben verwenden, die beim Zeichnen immer verwechselt werden.« Dennoch ,,werden diese Maßstäbe von anerkannten Firmen in allen DIN-Formaten hergestellt und in großen .Mengen abgesetzt. Der Grund hierfür liegt darin, daß die Maßstäbe genau und handlich sind.The building design theory of Prof. E. Neufert states on p. 21: »None Use measuring rods with different scales, which always get mixed up when drawing “Nevertheless, these standards are used by recognized companies in all DIN formats manufactured and sold in large quantities. The reason for this is that the scales are accurate and handy.
Der oben angeführte Nachteil wird durch die vorliegende Erfindung beseitigt, indem alle nicht benötigten Maßteilungen durch eine Hülle A abgedeckt werden, und so jeweils nur eine Maßteilung B verwendbar ist. Ein weiterer Vorteil liegt darin, daß die Kanten geschont werden.The above disadvantage is made by the present invention eliminated by covering all unneeded graduations with a cover A. and so only one graduation B can be used at a time. Another advantage lies in the fact that the edges are spared.
Die Zeichnung veranschaulicht in Abb. 1 eine Dreikantlatte mit sechs verschiedenen Maßteilungen, von denen jeweils fünf abgedeckt werden. Die Abb. I a zeigt diese Maßlatte im Ouerschn,itt sowie eine Ausführungsform der Befestigung am offenen Ende der Hülle. Die Abb. 2 veranschaulicht eine Maßlatte mit zwei Maßteilungen, von denen jeweils eine abgedeckt ist. Die Abb.2a zeigt den Querschnitt mit einer weiteren Form der Befestigung der Hülle. Entsprechend dem Erfindungsgedanken können auch die übrigen Formen von Maßlatten gegen eine Verwechselung der Maßteilungen abgedeckt werden.The drawing illustrates in Fig. 1 a triangular slat with six different graduations, five of which are covered. Fig. I. a shows this scale in cross section and an embodiment of the attachment at the open end of the shell. Fig. 2 shows a rule with two graduations, one of which is covered. The Fig.2a shows the cross section with a another form of attachment of the cover. According to the idea of the invention, you can also the other forms of yardstick against confusion of the graduation to be covered.
