Description
Die Erfindung betrifft ein Wandtafelzeichengerät nach dem Oberbegriff des Schutzanspruches 1. Als Anwendungsgebiet ist der Lehrbereich im weitesten Sinne, insbesondere Schulen, anzusehen.The invention relates to a blackboard drawing device according to the generic term of claim 1. The field of application is the teaching sector in the broadest sense, especially schools.
Üblicherweise werden zum Zeichnen verschiedenster geometrischer Formen unterschiedliche Zeichengeräte benutzt.Different drawing instruments are usually used to draw a variety of geometric shapes.
Die Aufgabe der Erfindung ist es, diese Nachteile zu beseitigen. Zur Lösung dieser Aufgabe vereinigt das Zeichengerät die Funktionen eines Geodreieckes, eines Winkelmessers und verschiedener Lineale.The aim of the invention is to eliminate these disadvantages. To solve this problem, the drawing device combines the functions of a set square, a protractor and various rulers.
Die Erfindung wird nachstehend anhand der Zeichnung beispielsweise beschrieben. The invention is described below by way of example with reference to the drawing.
Es zeigt:It shows:
Fig. 1 eine Draufsicht des Zeichengerätes Fig. 1 a top view of the drawing device
Das Zeichengerät besteht aus einem senkrechten Lineal 1, einem waagerechten Lineal 2 und einem senkrechten Lineal 3.The drawing device consists of a vertical ruler 1, a horizontal ruler 2 and a vertical ruler 3.
Nicht sichtbar sind die an der Unterseites des Lineals 1 befindlichen Magnete oder Saugfüße zur Fixierung des Gerätes auf der Tafeloberfläche.The magnets or suction cups on the underside of ruler 1 for fixing the device to the board surface are not visible.
Das Lineal 2 ist über das Gehäuse 7 gegenüber dem Lineal 1 vertikal und horizontal verschiebbar und über die im Gehäuse 7 angebrachte Festellknöpfe 4 und 5 arretierbar.The ruler 2 can be moved vertically and horizontally relative to the ruler 1 via the housing 7 and can be locked using the locking buttons 4 and 5 mounted in the housing 7.
Das Lineal 3 ist mit Hilfe des Feststellknopfes 6 drehbar mit dem Lineal 2 verbunden. Der Feststellknopf dient gleichzeitig der Arretierung des Lineals 3 gegenüber dem Lineal 2 in einer beliebigen Winkelstellung.The ruler 3 is connected to the ruler 2 by means of the locking knob 6. The locking knob also serves to lock the ruler 3 relative to the ruler 2 in any angular position.
Auf den Linealen 1 bis 3 befinden sich cm-Einteilungen und auf Lineal 2 zusätzlich kreisförmig um den Feststell knopf 6 herum angebracht eine Gradeinteilung. There are cm graduations on rulers 1 to 3 and on ruler 2 there is also a degree graduation in a circle around the locking button 6.
Mit Hilfe der Bohrungen 8 in Lineal 3 lassen sich bei gelöstem Feststell knopf 6 wie mit einem Zirkel Kreise zeichnen.With the help of the holes 8 in ruler 3, circles can be drawn as if with a compass when the locking knob 6 is loosened.
Wandtafelzeichengerät zur Verminderung der Anzahl der benötigten Zeichengeräte im Lehrbereich. Das Zeichengerät verbindet die Funktionen der herkömmlichen Zeichengeräte Geodreieck, Winkelmesser, Zirkel und Lineal.Blackboard drawing device to reduce the number of drawing devices required in the teaching area. The drawing device combines the functions of the conventional drawing devices: set square, protractor, compass and ruler.
Das Gerät wir mit Magneten oder Saugfüßen auf der Tafeloberfläche fixiert und eignet sich besonders zur Zeichnung von senkrecht aufeinander stehenden Linien.The device is fixed to the board surface with magnets or suction cups and is particularly suitable for drawing perpendicular lines.
