Description

Anordnung zur Verhinderung der Zeigerabnutzung bei mittels Fallbügels gesteuerten Regeleinrichtungen mit gleichzeitiger Anzeige oder Registrierung Die Erfindung betrifft eine Anordnung zur Verhinderung der Zeigerabnutzung bei mittels Fallbügels gesteuerten Regeleinrichtungen mit gleichzeitiger Anzeige oder Registrierung. Es sind bereits solche Regeleinrichtungen bekannt, bei welchen der Zeiger von dem Fallbügel auf Kniehebel gedrückt wird, welche eine Steuerung oder Regelung eines Vorganl;es veranlassen. Zwischen den beiden Knieliebeln ist bei den bekannten Einrichtungen ein Zwischenraum angeordnet, damit bei Mittelstellung des Zeigers .ein freies Gleiten desselben zwischen den Hebeln möglich ist. Da es sieh hierbei meistens um sehr empfindliche Instrumente handelt, deren Zeiger - aus entsprechend leichtem Material hergestellt sein müssen, ist die Beanspruchung dieser Zeiger ver'hältn;is,mäßig groß, und es zeigt sich schon nach kurzer Betriebszeit eine starke Abnutzung der Druckflächen, die im erhöhten Maße dann auftritt, wenn der Zeiger viel in der Nähe der. Mittelstellung, also zwischen den beiden Regelgliedern, spielt. Da der Zeiger in diesem Fall gewöhnlich nicht genau in den Zwischenraten trifft, erfolgt fast bei jedesmaligem Auftreffen ein Abrutschen des Zeigers., so daß die Beanspruchung ungewöhnlich hoch ist.Arrangement to prevent pointer wear by means of a drop bracket controlled regulating devices with simultaneous display or registration The The invention relates to an arrangement for preventing pointer wear at means Drop bar controlled control devices with simultaneous display or registration. There are already such control devices are known in which the pointer of the Drop bracket is pressed on toggle lever, which controls or regulates a Proceed; cause it. Between the two knee gables is in the known devices A space is arranged so that when the pointer is in the middle position, it can slide freely the same between the levers is possible. Since this is mostly very sensitive Instruments whose pointers - made of appropriately light material must be, the stress on these pointers is relative; is, moderately large, and es After a short period of operation, the printing surfaces show severe wear, which occurs to a greater extent when the pointer is much near the. Middle position, So between the two control elements, plays. As the pointer in this case usually does not hit exactly in the intermediate rates, occurs almost every time it hits slipping of the pointer., so that the stress is unusually high.

Um diesem Mangel abzuhelfen, ist gemäß der Erfindung zwischen den mit einer Steuervorrichtung verbundenen Regelgliedern ein federnder Anschlag vorgesehen, welcher beim Herunterdrücken dem Zeiger in der Mittelstellung eine Auflage bietet und dadurch einem vorzeitigen Verschleiß vorbeugt. In der Abbildung bedeutet i den Fallbügel, welcher periodisch auf den Zeiger 2 heruntergedrückt wird und der bei Ablenkung des Zeigers aus der Mittelstellung die Regelglieder 3 und q, beeinflußt. Beim Herunterdrücken des einen oder anderen Gliedes wird beispielsweise ein Servomotor betätigt.To remedy this deficiency, is according to the invention between a resilient stop is provided for regulating members connected to a control device, which, when pressed down, provides a support for the pointer in the middle position and thus prevents premature wear. In the figure i means den Drop bracket, which is periodically pressed down on the pointer 2 and the at Deflection of the pointer from the center position affects the control elements 3 and q. When one or the other link is pressed down, a servomotor, for example, is activated actuated.

In der bezeichneten Stellung würde der Zeiger 2 (bei NiAtvorhandeneeineines Anschlages) bieiin Auftreffen auf -das Regelg lIed 4. "schief gedrückt werden und würde abrutschen. Hierdurch würde in großer Verschleiß der Druckstelle am Zeiger eintreten. Um dies zu verhindern; ist zwischen den beiden Regelgliedern ein federnder Anschlag 5 vorgesehen, welcher .eine gute' Auflage für den Zeiger 2 auch in der Mittelstellung gewährleistet. Ein Kippen des Zeigers ist bei dieser Anordnung nicht möglich, und seine Lebensdauer wird dadurch wesentlich erhöht.In the position indicated, the pointer 2 (if NiAt is present, one Stop) when hitting the control element 4. "are pressed at an angle and would slide off. This would result in great wear and tear on the pressure point on the pointer enter. To prevent this; is a resilient one between the two control elements Stop 5 is provided, which "a good" support for the pointer 2 also in the Central position guaranteed. With this arrangement there is no tilting of the pointer possible, and its service life is thereby significantly increased.
