Description

Federkippsp@nn efür Gasmesser Die Erfindung bezieht sich auf die Anordnung einer Druckfeder bei solchen Kippspannwerken für Zweikammergasmesser, bei denen die Feder einen Schwingweg zurücklegt, und bezweckt, die Sicherheit der Funktion der Feder zu erhöhen. Die an sich bekannte Anwendung einer Druckfeder zu diesem Zweck, welche die für die Lebensdauer einer Feder gefährdeten Ösen von Zugfedern beseitigt, hat den Nachteil, daß, wenn diese Druckfeder ,an irgendeiner Stelle bricht, die Umschaltwirkung der Feder aufhört.Spring tilting clamps for gas meters The invention relates to the arrangement a compression spring in such tilting clamping mechanisms for two-chamber gas meters, in which the spring covers an oscillation path and aims to ensure the reliability of the function to increase the spring. The per se known application of a compression spring to this Purpose, which is the endangered life of a spring eyelets of tension springs eliminated, has the disadvantage that if this compression spring breaks at any point, the switching effect of the spring ceases.

Die Druckfeder bei solchen Kippspannwerken auf zwei ineinander verschiebbare Führungsbolzen anzuordnen, ist bekannt. Bei diesen bekannten Ausführungen besteht jejedoch der Nachteil, daß die freie Länge des inneren, in dem äußeren Führungsbolzen hin und her gehenden Führungsteiles, in den beiden Endstellungen der Schwingbewegung wesentlich größer ist als der Durchmesser der Windungen der den äußeren und inneren Führungsbolzen umgebenden Feder, so daß bei Bruch der Feder an irgendeiner Stelle die beiden zusammenhanglosen Federteile ausknicken können und somit ein weiteres Arbeiten. des Kippspannwerkes in Frage stellen.The compression spring in such tilting clamping units on two mutually displaceable Arranging guide pins is known. In these known designs there is However, the disadvantage that the free length of the inner, in the outer guide pin reciprocating guide part, in the two end positions of the oscillating movement is much larger than the diameter of the turns of the outer and inner Guide pins surrounding the spring, so that if the spring breaks at any point the two unrelated spring parts can buckle and thus another Work. of the tilting clamping mechanism into question.

Gemäß der Erfindung ist dieser Nachteil dadurch beseitigt worden, daß die Feder an den als Führungshülse ausgebildeten äußeren Führungsbolzen anliegt und der in den beiden Endstellungen des Kippspannwerkes von der Hülse frei gelassene Teil des inneren Führungsbolzens höchstens gleich dem äußeren Durchmesser der Federführung ist. Bei einer derartigen Anordnung kann jetzt kein Ausknicken der Feder mehr aeintreten, auch dann nicht, wenn ein Bruch an einer oder mehreren Stellen. der Feder erfolgt.According to the invention, this disadvantage has been eliminated by that the spring rests against the outer guide pin designed as a guide sleeve and the one left free by the sleeve in the two end positions of the tilting clamping mechanism Part of the inner guide pin is at most equal to the outer diameter of the spring guide is. With such an arrangement, the spring can no longer buckle, not even if there is a break in one or more places. the spring takes place.

Die Abbildungen zeigen ein Ausführungsbeispiel des Erfindungsgegenstandes. Abb. i zeigt :eine Gesamtansicht bei abgenommener Vorderwand und Abb. 2 die Druckfeder mit, ihrer Führung im Grundriß.The figures show an exemplary embodiment of the subject matter of the invention. Fig. I shows: an overall view with the front wall removed and Fig. 2 the compression spring with, their leadership in the ground plan.

In der Zeichnung ist mit g das äußere Gehäuse des Gasmessers bezeichnet. Die Fedor des Kippspannwerkes ist mit f bezeichnet und auf :einer Führungshülse angeordnet, in die ein verschiebbarer Führungsbolzen eingeschoben ist. An den Stellena und b sind diese beiden Führungsteile durch Gelenke dl und d2 mit dem Antriebshebelle und dem Umschlaghebel ' verbunden. Der Antriebshebele führt eine Schwingbewegung in der senkrecht zur Zeichnung stehenden Ebene (Abb. i) aus, so daß die beiden Führungsteile der Druckfeder f aus der dargestellten Endstellung eine Schwingbewegung ausführen, bei welcher sie sich zusammenschieben. Wie Abb. 2 erkennen läßt, ist nun die freie Länge s des in der Hülse eingeschobenen Führungsbolzens in der dargestellten Endstellung der Schwingbewegung kleiner oder ebenso groß wie der äußere Durchmesser D der Federwindung, so daß die Arbeitsweise der Feder auch dann aufrechterhalten wird, wenn diese an einer Stelle dieser freien Länge s zu Bruch geht.In the drawing, g denotes the outer housing of the gas meter. The spring of the tilting clamping mechanism is denoted by f and on: a guide sleeve arranged, into which a displaceable guide pin is inserted. At the Stellena and b are these two guide parts through joints dl and d2 with the drive lever and the envelope lever 'connected. The drive lever performs an oscillating movement in the plane perpendicular to the drawing (Fig. i), so that the two guide parts the compression spring f perform an oscillating movement from the illustrated end position, at which they push themselves together. As Fig. 2 shows, it is now free Length s of the guide pin pushed into the sleeve in the end position shown the oscillation movement is smaller or as large as the outer diameter D of the spring coil, so that the function of the spring is maintained even if it is on a point of this free length s breaks.
