Description

Sicherung gegen das Uberspringen der Spiralfeder bei Uhren, speziell Armbanduhren Die Erfindung betrifft eine Sicherung gegen das Überspringen der Spiralfeder über Klötzchen und Spiralschlüssel. Es ist schon eine Sicherung bekannt, bei der durch einen radialen Ansatz vom Spiralschließer das Überspringen der Spiralfeder nach unten verhindert werden soll. Dieser radiale Ansatz ist aber nur bei Weckern bekannt, da er sich bei Armbanduhren wegen des knappen Raumes schwer anbringen läßt. Diesen Nachteil bei den bekannten Uhren zu vermeiden, ist Zweck der vorliegenden Erfindung. Das Neue der Erfindung besteht darin, daß eine Schutzkappe auf den Unruhkloben gesetzt ist, die sich eng am Spiralklötzchen und am Spiralschließer außen anlegt und hierdurch um die Spiralfeder einen geschlossenen Ring in Form einer Kappe bildet. Hierdurch ist ein Verhaken der Spiralfeder am Spiralklötzchen und Spiralschließer unmöglich gemacht. An Hand der Zeichnung soll in schematischer Darstellung an einem Ausführungsbeispiel die Erfindung näher erläutert werden. Es zeigt Abb. 1 die Schutzkappe aufgesetzt auf einen Unruhkloben in Draufsicht, Abb. 2 die seitliche Ansicht von Abb. 1.Protection against jumping over the spiral spring in watches, especially Wristwatches The invention relates to a safeguard against jumping over the spiral spring over blocks and spiral wrench. A backup is already known in which The spiral spring skips over by a radial approach from the spiral closer down should be prevented. This radial approach is only applicable to alarm clocks known because it is difficult to attach to wristwatches because of the limited space available. The purpose of the present invention is to avoid this disadvantage in the case of the known clocks Invention. The novelty of the invention is that a protective cap on the balance cock is set, which fits tightly to the spiral block and the spiral closer on the outside and thereby forms a closed ring in the form of a cap around the spiral spring. This causes the spiral spring to get caught on the spiral block and spiral closer made impossible. On the basis of the drawing should be a schematic representation of a Embodiment the invention will be explained in more detail. Fig. 1 shows the protective cap placed on a balance cock in plan view, Fig. 2 the side view of Fig. 1.

Die Schutzkappe 1 besteht aus einem gestanzten Blech, welches mit Schrauben 2 und 3 auf den Unruhkloben 4 aufgeschraubt ist. Der untere Teil der Schutzkappe 1 bildet bis zum Kloben 4 einen geschlossenen Ring 6, der sich an Klötzchen 8 und Spiralschließer 7 eng anlegt, so daß keine Lücke zwischen ihm und Klötzchen 8 und Spiralschließer 7 vorhanden ist. Hierdurch wird auch bei erheblichen Stößen aus beliebigen Richtungen ein Verhaken der Spiralfeder 5 unmöglich gemacht und mit Sicherheit verhütet. Die Schutzkappe 1 hat Fensteröffnungen, so daß eine gute Übersicht zur Spiralfeder 5 und Unruh gegeben ist. Der wesentliche Vorteil der Schutzkappe liegt darin, daß sie leicht auch nachträglich in jedes Uhrwerk eingebaut werden kann, während die bekannten Sicherungen schon während der Teilefertigung angebracht werden müssen.The protective cap 1 consists of a stamped sheet metal, which with Screws 2 and 3 are screwed onto the balance cock 4. The lower part of the protective cap 1 forms a closed ring 6 up to the block 4, which is attached to blocks 8 and Spiral closer 7 fits tightly so that there is no gap between him and blocks 8 and Spiral shutter 7 is present. This is also in the event of significant impacts any direction hooking of the spiral spring 5 made impossible and with certainty prevent. The protective cap 1 has window openings, so that a good overview for Spiral spring 5 and balance wheel is given. The main advantage of the protective cap lies in that it can easily be retrofitted into any clockwork, while the known fuses are already attached during parts production have to.
