Abstract
Description
Die Erfindung betrifft ein Anzeigeinstrument zur Verwendung in einem Fahrzeug mit einem Zeigerschaft und einer Zeigerspitze, die separat davon ausgeführt und zur Befestigung am Zeigerschaft bestimmt ist.The The invention relates to a display instrument for use in a Vehicle with a pointer shaft and a pointer tip, separate executed and determined for attachment to the pointer shaft is.

Aus
der
Aufgabetask
Der Erfindung liegt die Aufgabe zugrunde, ein Anzeigeinstrument anzugeben, bei dem die Streulichteffekte verringert sind.Of the Invention has for its object to provide a display instrument where the stray light effects are reduced.
Lösungsolution
Die Aufgabe wird erfindungsgemäß gelöst durch ein Anzeigeinstrument mit einem Zeigerschaft, der rückseitig einer Skalenscheibe entlang einer Drehachse drehbeweglich angeordnet ist und an seinem anderen Ende mit einer winkelförmig gestalteten, lichtleitend ausgebildeten Zeigerspitze ausgestattet ist, welche in Richtung auf die Drehachse weist und mit einer Lichtquelle zusammenwirkt, wobei zumindest der parallel zur Drehachse verlaufende Teil der Zeigerspitze von einem Abschattungsmittel umschlossen wird. Durch dieses Abschattungsmittel wird die Ausbreitung von vagabundierenden Lichtanteilen verhindert und somit eine Verringerung des Hell-Dunkel-Kontrasts vermieden.The The object is achieved by a gauge with a pointer shaft, the back a dial plate along a rotational axis rotatably arranged is and at its other end with an angular shaped, light-conducting trained pointer tip is equipped, which pointing in the direction of the axis of rotation and cooperating with a light source, wherein at least parallel to the axis of rotation extending part of Pointer tip is enclosed by a shading agent. By this shading agent becomes the propagation of stray light components prevents and thus a reduction of the light-dark contrast avoided.
Als geeignetes Mittel kommt jegliches lichtundurchlässige Material in Betracht. Es kann sich dabei um eine auf die Zeigerspitze aufgebrachte Beschichtung handeln, mit Licht absorbierenden oder Licht reflektierenden Eigenschaften.When suitable agent is any opaque material into consideration. It can be applied to the pointer tip Coating act with light-absorbing or light-reflecting Properties.
In einer bevorzugten Ausführungsform ist das Abschattungsmittel als ein von der Zeigerspitze separates Bauteil ausgeführt. Diese Variante hat den Vorteil, dass geringfügige Schäden an Oberflächen lichtleitender Bauteile des Anzeigeinstruments, welche bei der Fertigung entstehen können, das betreffende Bauteil nicht unbrauchbar machen: der durch die Schadstelle verursachte Lichtaustritt wird von dem separat vorgesehenen Abschattungsmittel in seiner Ausbreitung gestoppt.In In a preferred embodiment, the shading means as a separate from the pointer tip component. This variant has the advantage of minor damage on surfaces of light-conducting components of the indicating instrument, which can arise during production, the relevant Do not render the component unusable: that caused by the damaged area Light emission is from the separately provided shading stopped in its spread.
Eine weitere bevorzugte Ausführungsform sieht vor, dass die Zeigerspitze oder das Abschattungsmittel oder beide als Baugruppe ausgebildet sind, die durch eine Rastverbindung an dem Zeigerschaft befestigt ist. Damit wird eine Montageerleichterung in mehrfacher Hinsicht bewirkt. Erstens kann die Vollendung der Zeigerform zu einer Hakenkontur – wie der Fachmann weiss, sind solche Zeiger schwieriger zu montieren – auf einen passenden Montageschritt gelegt werden; zweitens ist damit ein Anzeigeinstrument angegeben, dessen Erscheinungsbild einfach modifizierbar ist: Farbe, Form, Abmessungen der Zeigerspitze, evtl. mit daran angepasstem Abschattungsmittel, sind variierbar, ohne dass die Bauform des Instruments geändert werden müsste.A Another preferred embodiment provides that the Pointer tip or the shading agent or both as an assembly are formed by a latching connection to the pointer shaft is attached. This is a mounting relief in multiple Regard causes. First, the completion of the pointer shape can a hook contour - as the expert knows, are such Pointer harder to assemble - on a fitting assembly step be placed; secondly, this indicates a display instrument, whose appearance is easily modifiable: color, shape, Dimensions of the tip of the pointer, possibly with shading means adapted to it, are variable without changing the design of the instrument would have to be.
Um eine Variabilität etwa der Stärke oder Farbe des Lichts zu ermöglichen, kann die Baugruppe auch die Lichtquelle beinhalten, mit welcher die Zeigerspitze zusammenwirkt; anstelle dessen ist die Integration eines Filters in die Baugruppe möglich, der zwischen Lichtquelle und Zeigerspitze wirkt.Around a variability about the strength or color of the To allow light, the assembly can also be the light source include, with which the pointer tip cooperates; instead of this is the integration of a filter in the assembly possible, the between light source and pointer tip acts.
Es gibt Vorteile, die für den Einsatz eines zusätzlichen Befestigungsmittels, etwa eines Clips, beim Herstellen der Rastverbindung sprechen. Damit kann eine leicht lösbare Verbindung erzielt werden. Das Erscheinungsbild ist dann auch noch nach Ende der Fabrikation eines erfindungsgemäßen Anzeigeinstruments mit geringem Aufwand änderbar.It There are advantages to using an extra Fastener, such as a clip when making the locking connection speak. This can be achieved an easily detachable connection become. The appearance is then even after the end of the fabrication a display instrument according to the invention with modest effort.
Die Position der Lichtquelle, welche die Zeigerspitze versorgt, kann zugleich an anderen Erfordernissen ausgerichtet werden. Neben der bereits angesprochenen Integration in die Baugruppe, was eine Weise der Anordnung an dem der Drehachse abgewandten Ende des Zeigerschaftes darstellt, kann die Lichtquelle ebenso von der Zeigerspitze entfernt positioniert sein, falls für eine Lichtleitung zur Überbrückung der dann zwischen Quelle und Spitze bestehenden Distanz Sorge getragen wird. Eine Möglichkeit wäre eine entsprechende Ausbildung des Zeigerschafts, durch Einsatz eines lichtleitenden Kunststoffs für seine Herstellung.The Position of the light source, which supplies the pointer tip can at the same time be aligned to other needs. In addition to the already mentioned integration into the assembly, what a way the arrangement on the end remote from the axis of rotation of the pointer shaft represents, the light source can also be removed from the pointer tip be positioned if for a light pipe for bridging then the distance between source and peak existing distance taken care becomes. One possibility would be a corresponding one Formation of the pointer shaft, by using a photoconductive plastic for its production.
Als Grund für eine solche Position kommt u. a. eine Mehrfachnutzung der Lichtquelle, auch für die Versorgung anderer Komponenten des Anzeigeinstruments, in Betracht.When Reason for such a position comes u. a. a multiple use the light source, also for the supply of other components of the indicating instrument.
