Abstract

The rotating tip apparatus consists of a plate which contains a rotating tip. This plate is held on the flanks of a saddle bow arranged on the drawing instrument by means of a tongue-and-groove device and can perform a rocking movement thereon, as a result of which the rotating tip can be moved upwards and downwards into a position just in front of the drawing edge. <IMAGE>

Description

Die Erfindung betrifft die besondere Ausgestaltung einer Drehspitzenvorrichtung für Zeichengeräte der Gruppe Maß­ stabs- und Winkelschablonen gemäß Oberbegriff des Patent­ anspruchs.The invention relates to the special configuration of a Rotary tip device for drawing devices in the Dimension group rod and angle templates according to the preamble of the patent demanding

Drehspitzenvorrichtungen sind bereits in vielfältigen Va­ riationen vorgeschlagen worden. So ist z. B. aus der CH-PS 4 24 532 eine Drehspitzenvorrichtung bekannt, deren Dreh­ spitze an einem, an der Maßstabs- oder Winkelschablone be­ festigten Plättchen angeordnet ist und aufwärtsbeweglich ausgebildet ist.Rotary tip devices are already in diverse Va rations have been proposed. So z. B. from the CH-PS 4 24 532 a rotating tip device known, the rotation point on one, on the scale or angle template consolidated platelet is arranged and movable upwards is trained.

Der Erfindung liegt die Aufgabe zugrunde, eine Drehspitzen­ vorrichtung für Zeichengeräte zu schaffen, die einfach am Zeichengerät angebracht werden kann, wobei am Zeichengerät selbst nur unerhebliche Veränderungen erforderlich sind.The invention has for its object a rotary tips device for drawing devices that are easy to create Drawing device can be attached to the drawing device even minor changes are required.

Diese Aufgabe wird erfindungsgemäß durch die Merkmale des kennzeichnenden Teils des Anspruchs gelöst. Der Sattelbogen ist dabei an der Zeichenschablone in einer Weise angebracht, daß sich für die Drehspitze ein Einstich knapp vor der Zei­ chenziehkante ergibt. Die Drehspitze läßt sich auf einfache Art und Weise in die Funktionslage bringen und aus der Zei­ chenziehkante wieder entfernen, ohne einen störenden Einfluß auf den Zeichenablauf hervorzurufen; im Gegenteil, es läßt sich flüssiger und bequemer zeichnen, da Sattelbogen und Tellerplättchen so aufeinander abgestimmt und ausgebildet sind, daß die Drehspitze in der Funktionslage bzw. Bereit­ schaftsstellung ohne Fingerdruck verharrt. This object is achieved by the features of characterizing part of the claim solved. The saddle bow is attached to the drawing template in a way that there is a puncture just before the time for the turning tip pulling edge results. The rotating tip can be easily Bring the way into the functional position and out of time Remove the pulling edge again without any disruptive influence to evoke the drawing sequence; on the contrary, it leaves draw more fluently and more comfortably, since saddle bow and Plate plates so coordinated and designed are that the rotating tip in the functional position or ready position remains without finger pressure.  

Erreicht wird dieser Zustand, indem das Tellerplättchen nicht zu leichtgängig über den Sattelbogen wippend hin­ wegwandert, sondern nur durch mäßig-starken Fingerdruck in die Arbeits- bzw. Bereitschaftsstellung gebracht werden kann.This condition is achieved by the plate not rocking smoothly over the saddle arch wanders away, but only by moderately strong finger pressure be brought into the work or standby position can.

Die Erfindung wird anhand eines Ausführungsbeispiels er­ läutert. Es zeigtThe invention is based on an exemplary embodiment purifies. It shows

Fig. 1 eine Vorderansicht der Drehspitzenvorrichtung mit abgehobenem Tellerplättchen; Figure 1 is a front view of the rotating tip device with the plate plate lifted.

Fig. 2 eine Seitenansicht der Drehspitzenvorrichtung in der Funktionslage und in der Bereitschaftsstellung. Fig. 2 is a side view of the rotating tip device in the functional position and in the standby position.

In Fig. 1 sieht man das abgehobene Tellerplättchen (12) mit der Drehspitze (13) über dem Sattelbogen (11), mit dem es, wenn es mit der Nut- (16) und Federeinrichtung (15) einge­ rastet ist, zusammenarbeitet. Dabei wandert das Tellerplätt­ chen (12) durch Fingerdruck über den Sattelbogen (11) wip­ pend hinweg. Die Drehspitze (13) kommt dabei, wie in Fig. 2 ersichtlich aus der Einstichposition knapp vor der Zeichen­ ziehkante in eine abgehobene und etwas zurückliegende Posi­ tion zu stehen. Sie gibt dabei die Zeichenziehkante für ein ungehindertes Durchziehen des Zeichenstiftes frei. Dadurch wird das Zeichengerät in seiner ursprünglichen Funktion nicht beeinträchtigt, sondern dessen Einsatzbereich erwei­ tert sich im großen Maße. So können z. B. Winkel im Schwenk­ verfahren oder auch Kreise und Bögen mittels zusätzlich an­ gebrachter Löcher schnell und präzise gezeichnet werden.In Fig. 1 you can see the lifted plate ( 12 ) with the rotating tip ( 13 ) over the saddle bow ( 11 ), with which it, when it is engaged with the tongue ( 16 ) and spring device ( 15 ), works together. The plate plate ( 12 ) moves over the saddle arch ( 11 ) wip pend away by finger pressure. The turning tip ( 13 ) comes, as can be seen in Fig. 2 from the puncture position just before the drawing edge to stand in a raised and somewhat back position. It releases the drawing edge for an unimpeded pulling through of the drawing pen. As a result, the original function of the drawing device is not impaired; So z. B. Angle swivel or circles and arches can be drawn quickly and precisely using additional holes.

Die Drehspitzenvorrichtung stellt somit eine gewinnbringende Bereicherung der zeichnerischen Möglichkeiten dar, und ist zum Einsatz an Zeichenschablonen bekannter Art, wie z. B. das Geometrie-Dreieck hervorragend geeignet.The rotating tip device is thus a profitable one Enrichment of the drawing possibilities, and is for use on drawing templates of a known type, such as. B. that Geometry triangle ideally suited.
