Description
Zeiehenwinkel. Zeichenwinkel, in deren Fläche Figuren, wie greise, Ellipsen, Hyperbeln usw. ein gearbeitet sind, sind bekannt, nicht aber sol che mit geraden Ausnehmungen, mit denen verschiedene Winkel anreissbar sind.
Gegenstand der vorliegenden Erfindung ist ein Zeichenwinkel, der aus durchsichtigem oder undurchsichtigem Material, beispiels weise aus Zelluloid, Holz oder dergl. be stehen kann und sich dadurch auszeichnet, dass er mit Ausnehmungen versehen ist, durch welche zu den äussern Anschlag winkeln des Zeichenwinkels noch weitere Winkel anreissbar sind.
In der Zeichnung ist der Erfindungs gegenstand in zwei beispielsweisen Ausfüh rungsformen dargestellt, und zwar zeigt: Fig. 1 einen gleichschenkligen, rechtwink ligen Zeichenwinkel mit zwei Ausnehmungen und Fig. 2 einen ungleichschenkligen, recht winkligen Zeichenwinkel mit zwei in der Form anders gestalteten Ausnehmungen.
Gemäss dem ersten Ausführungsbeispiel besitzt der Zeichenwinkel 1 zwei Ausneh- mungen 2 und 3, durch die, ohne dass der Zeichenwinkel 1 in seiner Lage verändert zu werden braucht, verschiedene Winkel anreiss- bar sind.
Im zweiten Ausführungsbeispiel besitzt der Zeichenwinkel 1 zwei aus geradlinigen Dreiecken bestehende Ausnehmungen 2 und 3, durch die verschiedene Gegenwinkel an reissbar sind. Es ist selbstverständlich mög lich, dass die Ausnehmungen in dem Zeichen winkel auch in andern, aus geraden Linien bestehenden Formen, als wie dargestellt, be stehen können.
Durch diese Ausnehmungen wird ermög licht, dass verschiedene Teilwinkel von zum Beispiel 15 bis<B>90'</B> mit angeschlagenem Zeichenwinkel anreissbar sind, was in bezug auf ein rasches und exaktes Arbeiten als be deutender Vorteil bewertet wird.
Toe angle. Drawing angles, in the area of which figures such as old men, ellipses, hyperbolas, etc. are worked, are known, but not sol che with straight recesses with which different angles can be marked.
The subject of the present invention is a drawing angle, which can be made of transparent or opaque material, for example celluloid, wood or the like. Be and is characterized in that it is provided with recesses through which the outer stop angles of the drawing angle even more Angles can be marked.
In the drawing, the subject of the invention is shown approximately in two exemplary Ausfüh, namely shows: Fig. 1 an isosceles, right-angle drawing angle with two recesses and Fig. 2 is an unequal, right-angled drawing angle with two differently shaped recesses.
According to the first exemplary embodiment, the drawing angle 1 has two recesses 2 and 3, through which different angles can be marked without having to change the position of the drawing angle 1.
In the second embodiment, the drawing angle 1 has two recesses 2 and 3 consisting of straight triangles, through which different opposing angles can be torn. It is of course possible, please include that the recesses in the drawing angle in other, consisting of straight lines, shapes than as shown, be.
These recesses make it possible to mark different partial angles from, for example, 15 to <B> 90 '</B> with an attached drawing angle, which is rated as a significant advantage with regard to quick and precise work.
