Description
Tendenzanzeiger für Meßinstrumente Lose auf die Zeigerwelle aufgesetzte, im Gleichgewicht befindliche Hilfszeiger sind für Tendenzanzeige bei Meßinstrumenten bekannt; diesen bekannten Anzeigern gegenüber weist der vorliegende Erfindungsgedanke den Vorzug großer Einfachheit auf, den Vorzug geringster Reibungsverluste durch Wegfall von Hilfsbremsung und den Vorzug leichter Ablesbarkeit. Durch die ortsfeste Ablesung der Tendenzanzeige wird eine optische Vergrößerung der Anzeige durch feststehende Vorrichtungen ermöglicht.Trend indicators for measuring instruments loosely placed on the pointer shaft, Auxiliary pointers that are in equilibrium are for indicating tendencies in measuring instruments known; In contrast to these known indicators, the present inventive concept has the advantage of great simplicity, the advantage of minimal friction losses Elimination of auxiliary braking and the advantage of easier readability. Through the fixed Reading the tendency display is an optical enlargement of the display by fixed Devices allows.
Das Instrument erhält außer dein Hauptzeiger einen leichten, im Gleichgewicht befindlichen Tendenzzeiger t, der lose auf die Achse a des Hauptzeigers aufgesetzt wird. Der Drehwinkel dieses Tendenzzeigers ist durch Anschläge kurz begrenzt. Die Achse a des Hauptzeigers dreht also den Tendenzzeiger t bis zum Anschlag mit, wobei die ganz geringfügig gehaltene Reibung auf der möglichst dünnen Achse a zur Mitnahme genügt. Die Achse kann sich nach erfolgtem Anschlag des Tendenzzeigers selbstverständlich mit dem Hauptzeiger unter geringster Achsreibung weiterbewegen. Ändert sich die Drehrichtung der Achse a, dann wird der Tendenzanzeiger sofort in der anderen Richtung bis zum anderen Anschlag mitgenommen. Im Augenblick der Richtungsumkehrung ist also keine zusätzliche Bremskraft zu überwinden wie bei anderen Tendenzanzeigevorrichtungen.In addition to the main pointer, the instrument receives a light, balanced tendency pointer t, which is loosely placed on the axis a of the main pointer. The angle of rotation of this tendency indicator is briefly limited by stops. The axis a of the main pointer thus rotates the tendency pointer t as far as it will go, with the very slight friction on the axis a, which is as thin as possible, being sufficient for entrainment. After the tendency pointer has stopped, the axis can of course continue to move with the main pointer with minimal axial friction. If the direction of rotation of axis a changes, the tendency indicator is immediately taken along in the other direction up to the other stop. At the moment the direction is reversed, there is no additional braking force to overcome, as is the case with other tendency display devices.
Die verhältnismäßig geringe Hinundherbewegung des Tendenzanzeigers kann z. B. optisch sinnbildlich dargestellt werden. In Fig. 3 und q. der Zeichnung sind Hilfsskalen gezeigt, über und unter denen das Wort »steigt« und >>fällt« steht. Auf der Skala befindet sich lediglich ein ruhender Strich s, der ganz wenig schräg gestellt ist, vor ihr spielt der in entgegengesetzter Richtung ganz wenig schräg gestellte Tendenzzeiger t. Der Zeiger bildet also einen beweglichen Strich, der sich so über den festen Strich der Hilfsskala stellt, daß beide zusammen in einem Fenster eine Pfeilspitzenfigur ergeben. Bewegt sich in der dargestellten Weise der Tendenzzeiger t nach rechts bis zum Anschlag, dann zeigt die im Fensterausschnitt sichtbare Pfeilspitze nach oben auf das Wort :>steigt«. Bewegt er sich nach links, dann weist die Pfeilspitze nach unten auf das Wort »fällt,<.The relatively slight rocking of the trend indicator can e.g. B. are represented visually symbolically. In Fig. 3 and q. the drawing auxiliary scales are shown above and below which the words "rise" and "fall". There is only a stationary line s on the scale, which is very slightly oblique is posed, in front of her the one plays in the opposite direction very slightly diagonally set trend indicator t. The pointer thus forms a moving line, the is positioned over the solid line of the auxiliary scale so that both together in one Window result in an arrowhead figure. The moves in the manner shown The tendency pointer t to the right as far as it will go, then the im shows Window cutout visible arrowhead pointing upwards on the word:> increases «. If he moves to the left, then the arrowhead points downwards to the word "falls".
Weitere Ausführungsbeispiele der Sichtbarmachung der Tendenzanzeige sind etwa verschiedene Beschriftungen oder farbige Streifen, die in einem schmalen Spalt der Hilfsskala erscheinen. Hierbei ist die ortsfeste Ablesung von Bedeutung, weil das Gewicht einer etwa notwendigen optischen Vergrößerungseinrichtung vom Zeigerwerk gänzlich getrennt bleibt.Further exemplary embodiments of the visualization of the trend display are about different labels or colored stripes in a narrow Gap of the auxiliary scale appear. The fixed reading is important here, because the weight of a possibly necessary optical magnifying device from the pointer mechanism remains completely separate.
