Description
Die Erfindung betrifft eine Zeigeranordnung für ein Zeigerinstrument, insbesondere in einem Kraftfahrzeug, nach der im Oberbegriff von Anspruch 1 näher definierten Art. Des weiteren betrifft die Erfindung ein Zeigerinstrument, insbesondere in einem Kraftfahrzeug, mit einem Zifferblatt und mit einer solchen Zeigeranordnung.The The invention relates to a pointer arrangement for a pointer instrument, in particular in a motor vehicle, according to the preamble of Claim 1 further defined type. Furthermore, concerns the invention is a pointer instrument, in particular in a motor vehicle, with a dial and with such a pointer arrangement.
Eine
gattungsgemäße Zeigeranordnung ist aus der
Nachteilig bei dieser bekannten Lösung ist jedoch das Erfordernis einer mehrteiligen Ausführung, da ein zusätzliches Teil in die eigentliche Zeigerabdeckung montiert wird. Durch dieses zusätzliche Teil ergibt sich ein größerer Aufwand, der mit höheren Kosten verbunden ist, und es ist eine bestimmte Mindestgröße der reflektierenden Schicht erforderlich, da ein solches zusätzliches Teil aufgrund seiner Montierbarkeit nicht beliebig klein ausgeführt sein kann. Ein weiterer Nachteil ist die verhältnismäßig geringe Effizienz der Reflexionsschicht, da diese aus einer weißen Farbe besteht.adversely however, in this known solution, the requirement is a multi-part design, as an additional Part is mounted in the actual pointer cover. Because of this additional part results in a larger one Hassle, which is associated with higher costs, and it is a certain minimum size of the reflective Layer required as such an additional part not made arbitrarily small due to its mountability can be. Another disadvantage is the relatively low Efficiency of the reflection layer, as these are made of a white Color exists.
Die
Nachteilig bei dieser bekannten Lösung ist jedoch der sehr große, unterhalb der Zeigerkappe entstehende Lichthof, da nur ein Bruchteil des Lichts in die Zeigerfahne eingeleitet wird. Dies führt zu einer zu geringen Ausleuchtung der Zeigerfahne, was beispielsweise durch eine Erhöhung der Dicke derselben kompensiert werden könn te. Da dies jedoch einen größeren Bauraum erfordert, stellt es ebenfalls keine sinnvolle Alternative dar.adversely However, in this known solution, the very large, below the pointer cap resulting halo, since only a fraction of the light is introduced into the pointer flag. this leads to too low illumination of the pointer flag, which, for example be compensated by increasing the thickness thereof could te. But this is a bigger one Requires space, it also provides no useful alternative represents.
Es ist daher Aufgabe der vorliegenden Erfindung, eine Zeigeranordnung für ein Zeigerinstrument zu schaffen, bei welcher die Zeigerfahne hell und insbesondere homogen ausgeleuchtet wird, die eine geringe Baugröße aufweist und mit verhältnismäßig geringem Aufwand hergestellt werden kann.It is therefore an object of the present invention, a pointer arrangement to provide for a pointer instrument in which the pointer flag bright and in particular homogeneously illuminated, which is a small Has size and with relatively low cost can be produced.
Erfindungsgemäß wird diese Aufgabe durch die in Anspruch 1 genannten Merkmale gelöst.According to the invention This object is achieved by the features mentioned in claim 1.
Durch die erfindungsgemäße Ausführung der Zeigerkappe aus wenigstens zwei unterschiedlichen Kunststoffmaterialien, von denen das eine galvanisierbar und das andere nicht galvanisierbar ist, ist es möglich, durch Aufbringen einer reflektierenden Schicht auf das galvanisierbare Kunststoffmaterial das in die Zeigerfahne eingeleitete Licht genau zu denjenigen Stellen zu transportieren, die für eine gute Lichteinleitung in die Zeigerfahne sorgen, sodass eine gleichmäßige Ausleuchtung derselben erreicht werden kann. Dadurch ergibt sich mit einer niedriger dimensionierten Beleuchtungseinrichtung und/oder mit einer geringeren Baugröße der gesamten Zeigeranordnung dieselbe Helligkeit wie bei aus dem Stand der Technik bekannten Lösungen. Durch diese gemäß der vorliegenden Erfindung erzielbare geringere Baugröße ist es möglich, filigranere Designwünsche zu erfüllen. Umgekehrt ist es bei Beibehaltung der bekannten Baugrößen möglich, eine größere Helligkeit der Zeigerfahne zu erreichen, was bei bestimmten Anwendungen vorteilhaft sein kann.By the embodiment of the pointer cap according to the invention from at least two different plastic materials, from one can be electroplated and the other can not be electroplated is, it is possible by applying a reflective layer on the galvanisable plastic material in the pointer vane to bring introduced light exactly to those places which ensure a good introduction of light into the pointer flag, so that a uniform illumination of the same can be achieved. This results in a lower dimensioned Lighting device and / or with a smaller size the entire pointer arrangement the same brightness as in the State of the art known solutions. By this according to the present invention achievable smaller size is it possible to fulfill filigree design wishes. Conversely, it is while maintaining the known sizes possible, greater brightness of the To reach pointer flag, which is advantageous in certain applications can be.
Vorteilhafterweise entstehen bei der erfindungsgemäßen Lösung trotz der höheren Leuchtdichte keine größeren Lichthöfe, da das vorhandene Licht aufgrund der gezielten Strahlenführung zum Großteil in die Zeigerfahne eingeleitet wird und damit an anderen Stellen keine Störung darstellen kann. Ein besonderer Vorteil der erfindungsgemäßen Lösung liegt des weiteren darin, dass die Zeigerkappe einteilig ausgeführt ist, wodurch ihre Herstellung nur einen sehr geringen Aufwand erfordert und viele verschiedene Formen darstellbar sind.advantageously, arise in the inventive solution despite the higher luminance no larger Halos because the existing light due to the targeted Beam guidance for the most part in the pointer flag is initiated and thus in other places no disturbance can represent. A particular advantage of the invention Solution is further that the pointer cap in one piece is executed, whereby their production only a very requires little effort and many different forms representable are.
Eine hinsichtlich einer exakten Einleitung von Licht in die Zeigerfahne besonders vorteilhafte Ausgestaltung der Erfindung kann darin bestehen, dass die reflektierende Schicht an einer der Beleuchtungseinrichtung gegenüberliegenden schrägen Fläche angeordnet ist.A for an accurate introduction of light into the pointer vane Particularly advantageous embodiment of the invention may be that the reflective layer on one of the illumination device arranged opposite oblique surface is.
Wenn in einer weiteren vorteilhaften Ausgestaltung der Erfindung vorgesehen ist, dass am Umfang eines die Zeigerkappe nach unten abschließenden Rings wenigstens eine weitere reflektierende Schicht angeordnet ist, so kann auch im unteren Bereich der Zeigerfahne eine homogene Ausleuchtung derselben erreicht werden.If provided in a further advantageous embodiment of the invention is that on the circumference of a closing the pointer cap down At least one further reflective layer arranged around is, so even in the lower part of the pointer flag a homogeneous Illumination of the same can be achieved.
Um eine besonders hohe Effizienz hinsichtlich der Menge des reflektierten Lichts zu erreichen, ist es als besonders vorteilhaft anzusehen, wenn die reflektierende Schicht Chrom aufweist.Around a particularly high efficiency in terms of the amount of reflected To reach light, it is to be regarded as particularly advantageous, when the reflective layer has chromium.
Ein Zeigerinstrument mit einem Zifferblatt und mit einer erfindungsgemäßen Zeigeranordnung ist den Merkmalen von Anspruch 10 zu entnehmen.A pointer instrument with a dial and with a pointer arrangement according to the invention can be found in the features of claim 10.
Weitere vorteilhafte Ausgestaltungen und Weiterbildungen ergeben sich aus den restlichen Unteransprüchen. Nachfolgend ist ein Ausführungsbeispiel der Erfindung anhand der Zeichnung prinzipmäßig dargestellt.Further advantageous embodiments and developments emerge the remaining dependent claims. Below is an embodiment the invention in principle with reference to the drawing shown.
