Abstract

The pointer mechanism has a drive between supporting and cover plates, its pointer and segment spindle being supported in the plates. The cover plate (2) is U-shaped, its two arms (13, 14) having lugs (15, 16) extending outwards and which are riveted to the flat support plate (1). Hollow rivets can be formed on the lugs, by which these are secured to the support plate. The design simplifies accurate assembly as compared with the conventional method, where pillars are used between the plates.

Anneliese Böhm, 824 Berchtesqaden-Unterau Zeigerwerk Die Anmeldung betrifft ein Zeigerwerk mit einem zwischen einer Trägerplatine und einer Deckplatine angeordneten Getriebe, dessen Zeiger- und Segmentwelle in den Platinen gelagert sind.Anneliese Böhm, 824 Berchtesqaden-Unterau Zeigerwerk The registration relates to a pointer mechanism with a between a carrier plate and a cover plate arranged gear, whose pointer and segment shaft stored in the plates are.

Solche Zeigerwerke werden als Ubertragungswerke von Meßqeräten verwendet und tasten eine Meßgröße ab, die sie in eine Zeigerdrehung übertragen, welche wiederum auf eine Skala abgestimmt ist. In solchen Zeigerwerken wird gewöhnlich ein Getriebe verwendet, das ein Zahnsegment aufweist, welches an einem Ende eines zweischenkeligen Hebels angeordnet ist, der auf der Segmentwelle befestigt ist und dessen anderes Ende gelenkig mit einem die Meßgröße anzeigenden Stellorgan verbunden ist. Das Zahnsegment greift in ein Ritzel auf der Zeigerwelle ein, die ihrerseits durch eine Spiralfeder einseitig vorgespannt ist.Such pointer mechanisms are used as transmission mechanisms for measuring devices and scan a measured variable, which they transfer to a pointer rotation, which in turn is tuned to a scale. A gear is usually used in such pointer movements used, which has a tooth segment, which at one end of a two-legged Is arranged lever, which is attached to the segment shaft and the other The end is articulated with an actuator indicating the measured variable. The tooth segment meshes with a pinion on the pointer shaft, which in turn is controlled by a spiral spring is biased on one side.

Bei den bekannten Zeigerwerken sind die Wellen in Platinen gelagert, die parallel zueinander und im Abstand voneinander angebrdnet sind. Die Halterung der Platinen relativ zueinander erfolgt durch Pfeiler, deren Enden mit den beiden Platinen der Deckplatine und der Trägerplatine gewöhnlich vernietet sind. Diese Befestigung der Platinen relativ zueinander hat sich bewährt, so daß sie trotz des großen Aufwandes bei der Herstellung von Zeigerwerken bevorzugt wird. Die aufwendige Fixierung der Platinen mit Pfeilern hat in der Wirtschaftlichkeitsberechnung der Herstellung von Zeigerwerken einen verhältnismäßig hohen Wert, so daß nach rationelleren Fertigungsmethoden gesucht wurde, jedoch bisher ohne Erfolg.In the known pointer movements, the shafts are stored in plates, which are parallel to each other and at a distance from each other. The bracket the sinkers relative to each other is carried out by pillars, the ends of which with the two Boards of the cover plate and the carrier plate are usually riveted. These Fastening the boards relative to each other has been proven, so that they despite the Great effort in the manufacture of pointer movements is preferred will. The complex fixing of the boards with pillars has in the profitability calculation the production of pointer movements a relatively high value, so that after more rational Manufacturing methods were sought, but so far without success.

Der Erfindung liegt daher die Aufgabe zugrunde, die Distanzierung von Träger- und Deckplatine eines Zeigermeßwerks so zu rationalisieren, daß Aufwand und Fertigungskosten wesentlich gesenkt werden können.The invention is therefore based on the object of the distancing to rationalize the carrier and cover plate of a pointer measuring mechanism so that effort and manufacturing costs can be reduced significantly.

Diese Aufgabe löst die Erfindung dadurch, daß die Deckplatine als U-Profil ausgebildet ist, dessen beide Schenkel nach außen weisende Laschen aufweisen, die mit der ebenen Trägerplatine vernietet sind. Vorzugsweise erfolgt die Vernietung mit Hohlnieten, die an den Laschen des U-Prbfils angeformt sind..This object is achieved by the invention in that the cover plate as U-profile is formed, the two legs of which have outwardly facing tabs, which are riveted to the flat carrier plate. The riveting is preferably carried out with hollow rivets, which are formed on the tabs of the U-test file ..

Es hat sichherausgestellt, daß durch diese Maßnahme nicht nur die Toleranzen der Distanzen von Trägerplatine und Deckplatine gleich gut wie bei der Distanzierung mit Pfeilern eingehalten werden können, sondern daß mit der Maßnahme nach der Erfindung sich die Zeiten für das Zusammensetzen der Zeigermeßwerke wesentlich verringern lassen und dadurch eine erhebliche Kosteneinsparnis bei der Herstellung dieser Werke möglich ist. Das Zusammenfügen von Deckplatine und Trägerplatine und die Vernietung der beiden Platinen miteinander lassen sich maschinell in einem Arbeitsgang mit einfachen Vorrichtung mühelos bewirken.It has been found that not only the Tolerances of the distances between carrier board and cover board are just as good as with the Distancing with pillars can be observed, but that with the measure According to the invention, the times for assembling the pointer measuring mechanisms are essential can be reduced and thereby a considerable saving in manufacturing costs this works is possible. The assembly of cover plate and carrier plate and the riveting of the two plates to one another can be done by machine in one operation effect effortlessly with a simple device.

Es wird hervorgehoben, daß die Trägerplatine bei einem Zeigerwerk nach der Erfindung eben sein muß, so daß die U-förmige Deckplatine auf ihr positioniert werden kann. Ein weiterer Vorteil der erfindungsgemäßen Maßnahme besteht.darin, daß zusätzliche Maßnahmen, die für die Komplementierung des Zeigermeßwerkes erforderlich sind, in den nunmehr ebene Fläche aufweisenden, die Distanz der Platinen einhaltenden Elementen leichter vorgenommen werden können, als in den bisher runden, als Pfeiler dienenden Drehteilen. So kann beispielweise das äußere Ende der die Zeigerwelle vorspannenden Spiralfeder mit einem einfachen Werkzeug in einen Schlitz eingeklemmt werden, der bis zum Rand eines der Flansche des U-förmigen Profils reicht. Bisher war es üblich, dieses äußere Ende in einer Bohrung eines Pfeilers mit einem Keil zu befestigen.It is emphasized that the carrier plate with a pointer mechanism according to the invention must be flat so that the U-shaped cover plate is positioned on it can be. Another advantage of the measure according to the invention is that that additional measures required for the complementation of the pointer measuring mechanism are, in the now flat surface, maintaining the distance between the boards Elements can be made more easily than in the previously round ones, as pillars used turned parts. For example, it can outer end of the the pointer shaft pretensioning the coil spring with a simple tool Slit that is clamped to the edge of one of the flanges of the U-shaped profile enough. Previously it was customary to place this outer end in a hole in a pillar to be fixed with a wedge.

Anhand der Figuren wird die Erfindung beispielsweise erläutert.The invention is explained by way of example with the aid of the figures.

Figur 1 zeigt eine Draufsicht auf ein Zeigerwerk nach der Erfindung, bei dem die Deckplatine teilweise durchbrochen dargestellt ist.Figure 1 shows a plan view of a pointer mechanism according to the invention, in which the cover plate is shown partially broken.

Die Figuren 3 und 3a zeigen Teilschnitte längs der Linie III-III in Figur 1, wobei in Figur 3 der unvernietete und in Figur 3a der vernietete Zustand der beiden Platinen zu sehen ist.Figures 3 and 3a show partial sections along the line III-III in FIG. 1, with the unriveted state in FIG. 3 and the riveted state in FIG. 3a of the two boards can be seen.

Bei dem in den Figuren dargestellten Zeigerwerk nach der Erfindung sind zwischen einer Trägerplatine 1 und einer Deckplatine 2 eine Zeigerwelle 3 und eine Segmentwelle 4 drehbar in diesen Platinen gelagert. Die Segmentwelle 4 trägt einen doppelschenkeligen Hebel 5, dessen einer Arm 6 als Zahnsegment ausgebildet ist und dessen anderer Arm 7 an seinem Ende eine öse 8 aufweist, mit der dieser Arm gelenkig mit einem Stellorgan verbunden werden kann, das entsprechend einer Meßgröße einen Hub ausführt, durch den der Hebel 5 um die Achse der Segmentwelle 4 gedreht werden kann, so daß das in das Ritzel 9 auf der Zeigerwelle eingreifende Segment gedreht wird und dadurch seinerseits über dieses Ritzel 9 eine Drehung der Zeigerwelle 3 bewirkt. Auf der Zeigerwelle 3 befindet sich weiter eine Spiralfeder 10, deren inneres Ende an einem Röllchen 11 und deren äußeres Ende in einem Schlitz 12 befestigt sind.In the pointer mechanism according to the invention shown in the figures are between a carrier plate 1 and a cover plate 2, a pointer shaft 3 and a segment shaft 4 rotatably mounted in these plates. The segment shaft 4 carries a double-leg lever 5, one arm 6 of which is designed as a toothed segment is and the other arm 7 at its end has an eyelet 8 with which this Arm can be articulated with an actuator, which according to a Measured variable executes a stroke through which the lever 5 about the axis of the segment shaft 4 can be rotated so that the meshing with the pinion 9 on the pointer shaft Segment is rotated and thereby in turn a rotation of this pinion 9 Pointer shaft 3 causes. There is further on the pointer shaft 3 a spiral spring 10, the inner end of which on a roller 11 and the outer end are fastened in a slot 12.

Das Wesentliche der Erfindung besteht darin, daß die Deckplatine 2, wie insbesondere aus Figur 2 ersehen werden kann, als U-Profil ausgebildet ist, an dessen stehenden Schenkeln 13 und 14 Laschen 15 und 16 befestigt sind, an die ihrerseits Hohlnieten 17 angeformt sind, welche durch Bohrung 18 in der Trägerplatine beim Zusammensetzen des Gerätes hindurchgeführt und wie in Figur 3a gezeigt, vernietet werden. Durch diese Ausbildung der Deckplatine als U-Profil läßt sich das Zusammensetzen des Zeigermeßwerkes wesentlich vereinfachen.The essence of the invention is that the cover plate 2, as can be seen in particular from Figure 2, is designed as a U-profile, on the standing legs 13 and 14 tabs 15 and 16 are attached to the in turn, hollow rivets 17 are formed, which through hole 18 in the carrier plate Passed through when assembling the device and riveted as shown in Figure 3a will.
