Description

Bei dem Sicherheitsschlüssel gemäß Patent 390569 stellt sich beim Gebrauch der Übelstand ein, daß sich die Mutter, welche den Gegenhalt für die Kupplungsfeder S bildet und zugleich zum Regeln der Federspannung dient, von selbst in dem Sinne dreht, daß die Federspannung vergrößert wird. Außerdem ist auch die Einstellung der Feder durch Drehung der im Innern des Schlüsselrohres befindlichen Mutter mittels eines Aufsteckschlüssels unbequem. Die Eifindung betrifft eine Einrichtung, durch welche diesen Übelständen abgeholfen wird, und die darin .besteht, daß die Gegenmutter als Glockenmutter ausgebildet ist, die gegen eine Weiterdrehung in sich gesichert ist, und daß die Spannungsregelung durch eine besondere, außeniliegende, leicht von Hand ohne Schlüssel einstellbare, auf einem Gewindestück des Schaftes sitzende Einstellmutter erfolgt.With the security key according to the patent 390569 the inconvenience arises when using it that the mother, which forms the counterhold for the clutch spring S and at the same time for regulating the spring tension serves, rotates by itself in the sense that the spring tension is increased. In addition, the setting is also the Spring by turning the nut inside the key tube by means of a socket wrench inconvenient. The invention concerns a device by which these evils is remedied, and which consists in the fact that the counter nut as Bell nut is formed which is secured against further rotation in itself, and that the voltage regulation by a special, external, easy by hand without a key adjustable adjusting nut sitting on a threaded piece of the shaft takes place.

Ein. Ausführungsbeispiel des Erfindungsgegenstandes ist durch Abb. 1 Im Schnitt und A. Embodiment of the subject matter of the invention is shown in Fig. 1 in section and

durch Abb. 2 in der Seitenansicht dazu dargestellt; Abb. 3 ist ein Querschnitt nach Linie A-B der Abb. 1.represented by Fig. 2 in side view; Fig. 3 is a cross section along line AB of Fig. 1.

In dem Schlüsselrohr 1 führt sich die Stange 2 der Kurbel 3. Auf der Stange sitzt die Kupplungsfeder 4, die sich mit dem einen Ende gegen den Absatz 5 im Schlüsselrohr 1 und mit dem anderen Ende gegen die mittels eines Schraubenziehers anziehbare Giockenmutter 6 am Ende der Kurbelstange 2 legt. Das Schlüsselrohr besitzt an seinem der Kurbel zugekehrten Ende Zahnlücken, in die die Zähne 7 der Kupplungsbüchse 8 eingreifen. Diese Kupplungsbüchse ist auf der Kurbelstange 2 verschiebbar und durch Nut und Feder gezwungen, an einer Drehung der Kurbelstange in dem Schlüsselrohr teilzunehmen, wenn bei einer gewissen Größe des Widerstandes der Triebfeder des Uhrwerks dieIn the key tube 1, the rod 2 of the crank 3 is seated on the rod the clutch spring 4, one end of which is against the shoulder 5 in the key tube 1 and with the other end against the giocken nut which can be tightened by means of a screwdriver 6 at the end of the connecting rod 2. The key tube has the crank on his facing end tooth gaps in which the teeth 7 of the coupling sleeve 8 engage. This coupling sleeve is displaceable on the connecting rod 2 and is forced by tongue and groove to rotate the connecting rod to participate in the key tube when at a certain level of resistance the mainspring of the clockwork

ao Spannung der Kupplungsfeder 4 nicht mehr ausreicht, die Kupplung in Eingriff zu halten. Die Spannung der Kupplungsfeder 4 kann durch Drehung der Einstellmutter 9, die auf einem Gewindestück der Kurbelstange 2 sitzt und sich gegen die Kupplungsbüchse 8 legt, geregelt werden. Das bei der Drehung der Kurbelstange 2 im Schlüsselrohr an dem Absatz 5 des Schlüsselrohres auftretende, widerstehende Reibungsmoment, welches die Mutter 6 auf den Kurbelschaft aufzudrehen strebt, wird durch die Ausbildung dieser Mutter als Glockenmutter unschädlich gemacht, so daß die einmal eingestellte Spannung der Feder 4 unverändert erhalten bleibt.ao tension of the clutch spring 4 is no longer sufficient to keep the clutch engaged. The tension of the clutch spring 4 can be adjusted by turning the adjusting nut 9, which is on a threaded piece of the connecting rod 2 sits and lies against the coupling sleeve 8, be managed. That when turning the connecting rod 2 in the key tube on the shoulder 5 of the key tube occurring, resisting frictional torque, which the nut 6 strives to turn on the crank shaft, is due to the training of this nut as Bell nut made harmless, so that the tension of the spring 4 remains unchanged.
