Description

Es ist hinreichend bekannt, daß beim Ziehen von mehreren Kreisbogen mit dem gleichen Mittelpunkt durch die starre sich mitdrehende Zirkelspitze im Einsatzpunkt oft größere Löcher entstehen, welche vor allem in den Lichtpausen als helle Stellen sichtbar sind.It is well known that when drawing multiple arcs with the same center point due to the rigid rotating compass tip at the point of use often larger holes arise, which are mainly in the blueprints as bright spots are visible.

Solche helle Stellen erschweren oft ein genaues Nachmessen und wirken zudem unschön. Gegenstand der Erfindung ist ein Zirkeleinsatz, welcher mit einem Kugelgelenk versehen ist.Such bright spots often make it difficult to measure accurately and are effective also ugly. The invention is a compass insert, which with a Ball joint is provided.

In der Zeichnung ist ein Ausführungsbeispiel des erfindungsgemäßen Geräts dargestellt.In the drawing is an embodiment of the invention Device shown.

Der Zirkeleinsatz besteht aus dem Befestigungsschaft a und dem Untersatz b.The compass insert consists of the fastening shaft a and the base b.

Das untere Ende des Befestigungsschaftes a ist als Kugel c ausgebildet.The lower end of the fastening shaft a is designed as a ball c.

An der Unterseite des Untersatzes b befindet sich die eigentliche Zirkelspitze d, die Oberseite ist als Kugelpfanne ausgebildet.At the bottom of the base b is the actual one Circle tip d, the top is designed as a ball socket.

Der Befestigungsschaft a ist mittels der Kugel c so in der Kugelpfanne des Unterteils b eingebördelt, däß derselbe nach allen Seiten schwenkbar ist.The fastening shaft a is in the ball socket by means of the ball c of the lower part b crimped so that it can be pivoted in all directions.

Um der Kugel c einen besseren Halt zu geben, ist der obere Rand des Unterteiles b mit einem Verstärkungsring c versehen.To give the ball c a better grip, the upper edge of the Lower part b is provided with a reinforcing ring c.

Beim Ziehen von Kreisen bleibt der Unterteil b mittels der Spitze d auf dem Papier stehen, während sich der Befestigungsschaft a mit dem Zirkel in dem Kugelgelenk dreht.When drawing circles, the lower part b remains by means of the tip d stand on the paper, while the fastening shaft a with the compass in the ball joint rotates.
