Description

Federzirkel Gegenstand der Erfindung äst ein Federzirkel mit Einstellspindel, der sich von den bekannten Zirkeln dieser Art dadurch unterscheidet, daß die Muttern der Einstellspindel in Ausschnitten der Zirkelschenkel um außerhalb der Spindelachse befindliche Zapfen schwenkbar gelagert sind.Spring compass The subject of the invention is a spring compass with adjusting spindle, which differs from the known circles of this type in that the nuts the setting spindle in sections of the compass legs around outside the spindle axis located pins are pivotably mounted.

Auf der Zeichnung ist der Erfindungsgegenstand in einem Ausführungsbeispiel dargestellt. Es zeigen den Zirkel: Abb. i in Seitenansicht und Abb. z im Schnitt nach der Linie A-A der Abb. i.The subject of the invention is shown in one embodiment in the drawing shown. The compasses show: Fig. I in side view and Fig. Z in section according to the line A-A of Fig. i.

Der Zirkel besteht in üblicher Weise aus dem federnden Bügel i mit den sich daran anschließenden Schenkeln 3 und 4, welche die Spitze 5 und die Reißfeder 6 tragen. Die Schenkel 3, 4 besitzen je ein Langloch 7, 8 für den Durchtritt der Einstellspindel 9 mit dem Fingerrad i o.The compass consists in the usual way of the resilient bracket i with the adjoining legs 3 and 4, which the tip 5 and the drawing pen 6 wear. The legs 3, 4 each have an elongated hole 7, 8 for the passage of the Adjustment spindle 9 with the finger wheel i o.

Auf der Innenseite der Schenkel 3, 4 erweitern sich die Langlöcher 7, 8 zu Längsschlitzen i i, welche am einen Ende von Zapfen 12 durchsetzt sind. Auf den Zapfen 12 schwingen in den Längsschlitzen i i Bogenstücke 13, welche Muttergewinde besitzen und mit diesem Muttergewinde die Einstellspindel 9 aufnehmen. Durch Verdrehen der Fingerscheibe i o und damit der Spindel 9 werden die Muttern 13 auf der Spindel 9 verschoben, und infolge des Kräftespiels zwischen Spindel 9 und Zapfen 12 erfolgt eine Verstellung der Schenkel bzw. der Spitze 5 und Reißfeder 6 gegeneinander. Gleichzeitig schwingen die Muttern 13 um ihre Zapfen 12 und erhalten in jeder Schenkellage ihre richtige Einstellung gegenüber Spindel 9 und Schenkeln 3, .4.On the inside of the legs 3, 4, the elongated holes 7, 8 widen to form longitudinal slots ii, through which pins 12 pass through at one end. On the pin 12 swing in the longitudinal slots ii arc pieces 13 which have nut threads and take up the adjusting spindle 9 with this nut thread. By turning the finger washer io and thus the spindle 9, the nuts 13 are moved on the spindle 9, and as a result of the play of forces between the spindle 9 and pin 12, the legs or tip 5 and tear spring 6 are adjusted relative to one another. At the same time, the nuts 13 swing around their pins 12 and receive their correct setting with respect to the spindle 9 and legs 3, .4 in each leg position.

Durch eine solche Lagerung der Spindelmuttern 13 werden die Gewindegänge von Spindel und Muttern immer gleichmäßig beansprucht und deren vorzeitige Zerstörung ausgeschaltet. Ebenso können innere Spannungen und Ermüdungserscheinungen in den Schenkeln nicht mehr auftreten, da der Spindeldruck von den Zapfen 12 aufgenommen wwrd.Such a storage of the spindle nuts 13, the threads always equally stressed by spindle and nuts and their premature destruction switched off. Internal tension and signs of fatigue can also occur in the Legs no longer occur because the spindle pressure is absorbed by the pin 12 wwrd.
