Description

Durch die Erfindung soll ein Lineal geschaffen «erden, das sich infolge seiner Elastizität an die Unterlage anschmiegt und zugleich durch seine Kippbarkeit einen schnellen, unmittelbaren Wechsel zwischen Bleistift- und Reißnadelzeichnen gestattet. . Es sind bereits Lineale im Gebrauch, bei denen die Elastizität dadurch erreicht wird, daß zwei übereinanderliegende federnde Leisten mit einer Zwischenlage aus weichem Material durch Niete so zusammengehalten werden, daß bei Krümmung des Lineals ein Verschieben der einzelnen Platten unter sich möglich ist. Diese Lineale sind in der Herstellung teuer und zudem nicht kippbar.The invention is intended to create a ruler which, as a result its elasticity clings to the base and at the same time thanks to its tiltability a quick, immediate switch between pencil and scriber drawing allowed. . There are already rulers in use that reduce the elasticity it is achieved that two superimposed resilient strips with an intermediate layer made of soft material are held together by rivets so that when the curvature of the Rulers can be used to move the individual panels among themselves. These rulers are expensive to manufacture and also cannot be tilted.

Der Erfindungsgegenstand ist auf der Zeichnung in einem Ausführungsbeispiel dargestellt, und zwar zeigt Fig. A eine Draufsicht, Fig. B eine Seitenansicht und Fig. C einen Querschnitt.The subject of the invention is shown in the drawing in an exemplary embodiment shown, namely Fig. A shows a plan view, Fig. B shows a side view and Fig. C is a cross section.

Die Kippbarkeit des Lineals bei gleichzeitiger Elastizität wird in einfacher Weise dadurch erreicht, daß auf der Unterseite eines elastischen Linealkörpers .4, der aus biegsamem Material, wie Stahlblech, Celluloid, biegsamem Glas usw., besteht, in seiner Längsrichtung, vorzugsweise in Linealmitte, kleine truppenartige Erhöhungen i in reihenförmiger Anordnung und in angemessenen Abständen als Kippkante angebracht werden. Durch diese Einrichtung wird eine Versteifung des Lineals vermieden, die dann eintreten würde, wenn der Linealkörper an Stelle der einzelnen Erhöhungen mit einer durchlaufenden Kippleiste versehen würde.The tiltability of the ruler with simultaneous elasticity is shown in easily achieved in that on the underside of an elastic ruler body .4 made of pliable material such as sheet steel, celluloid, pliable glass, etc., consists, in its longitudinal direction, preferably in the middle of the ruler, small troop-like Elevations i in a row and at appropriate intervals as a tilting edge be attached. This device avoids stiffening of the ruler, which would occur if the ruler body took the place of the individual bumps would be provided with a continuous tilting strip.

Die Kippbarkeit des Lineals ermöglicht in angenehmer Weise das Andrücken der Ziehkante 3 an die Unterlage bei genauen Arbeiten mit Zeichenstiften, während zur Reißnadelführung die Ziehkante durch leichten Fingerdruck augenblicklich in Stellung 2 nach oben zu bringen ist.The tiltability of the ruler makes it easy to press on the drawing edge 3 on the pad when working precisely with drawing pens while To guide the scriber, pull the drawing edge in at once by pressing lightly with your finger Position 2 is to be brought up.

Bei Schneidarbeiten bietet das mit den Erhöhungen nach oben liegende Lineal einen elastischen, gut anliegenden Schneidanschlag, wodurch ein glatter Papierschnitt gewährleistet wird.For cutting work, the one with the elevations at the top offers Ruler has a resilient, well-fitting cutting stop, creating a smooth paper cut is guaranteed.
