Description

Die Erfindung betrifft ein Anzeigeinstrument mit einem transparenten, lichtleitenden Zeiger, welcher derart auf einer Kappe einer Zeigerwelle befestigt ist, daß der Zeiger von der Stirnseite her in die Kappe eingesetzt und in ihr durch eine Klipsverbindung befestigt ist.The invention relates to a display instrument with a transparent, light-guiding pointer, which is fastened to a cap of a pointer shaft in such a way that the pointer is inserted into the cap from the end face and is fastened in it by a clip connection.

Ein derartiges Anzeigeinstrument ist aus der DE-A-32 01 571 bekannt. Durch diese Gestaltung kann der Zeiger nach der Montage der Kappe auf einfache Weise in diese eingesetzt werden. Deshalb ist auch ein nachträgliches Auswechseln des Zeigers leicht möglich.Such a display instrument is known from DE-A-32 01 571. With this design, the pointer can be inserted into the cap in a simple manner after assembly. It is therefore easy to change the pointer afterwards.

Der Erfindung liegt die Aufgabe zugrunde, ein Anzeigeinstrument der eingangs genannten Art derart zu gestalten, daß sein Zeiger besonders rasch montierbar und gegen einen anderen austauschbar ist sowie eine hohe Stabilität besitzt.The invention has for its object to design a display instrument of the type mentioned in such a way that its pointer is particularly quick to assemble and interchangeable with another and has a high stability.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Zeiger im wesentlichen über seine gesamte Länge in eine Rinne aus lichtundurchlässigem, zum Zeiger hin reflektierenden Material eingesetzt ist. Eine solche Rinne sorgt für eine sehr große Stabilität des Zeigers, da sie nicht lichtdurchlässig sein muß und deshalb aus einem Material bestehen kann, welches ausschließlich im Hinblick auf eine hohe Festigkeit auswählbar ist. Diese hohe Stabilität ist vor allem für erschütterungsstarke Fahrzeuge, insbesondere Dieselfahrzeuge, vorteilhaft. Hiervon abgesehen sorgt die Rinne dafür, daß das Licht aus dem Zeiger nur in Richtung des Betrachters austreten kann, so daß keine Lichtverluste zur Seite hin auftreten und der Zeiger auch bei Verwendung einer relativ schwachen Lichtquelle ausreichend leuchtet.This object is achieved in that the pointer is inserted over its entire length in a channel made of opaque material reflecting towards the pointer. Such a channel ensures a very high stability of the pointer, since it does not have to be translucent and can therefore consist of a material that is used only with a view to high strength can be selected. This high stability is particularly advantageous for vehicles with high levels of vibration, especially diesel vehicles. Apart from this, the channel ensures that the light can only emerge from the pointer in the direction of the viewer, so that no light losses occur to the side and the pointer shines sufficiently even when using a relatively weak light source.

Für eine Fertigung in großen Stückzahlen ist es vorteilhaft, wenn die Rinne einstückig mit der Kappe ausgebildet ist.For production in large quantities, it is advantageous if the channel is formed in one piece with the cap.

Alternativ ist es jedoch auch möglich, daß die Rinne in eine stirnseitige Nut der Kappe einsetzbar ist.Alternatively, however, it is also possible that the channel can be inserted into an end groove in the cap.

Die Rinne kann zusammen mit dem Zeiger auf einfache Weise durch eine Rastnase des Zeigers verrastet werden, wenn gemäß einer anderen Ausgestaltung der Erfindung der Zeiger zumindest eine durch einen Durchbruch der Rinne durchführbare und mit einer Rastfläche der Kappe verrastbare Rastnase hat.The channel can be locked together with the pointer in a simple manner by a latching lug of the pointer if, according to another embodiment of the invention, the pointer has at least one latching lug which can be carried out through an opening in the channel and can be latched to a latching surface of the cap.

Die Erfindung läßt zahlreiche Ausführungsformen zu. Zur weiteren Verdeutlichung ihres Grundprinzips ist eine davon in der Zeichnung dargestellt und wird nachfolgend beschrieben.The invention permits numerous embodiments. To further clarify its basic principle, one of these is shown in the drawing and is described below.

Die Zeichnung zeigt perspektivisch in Explosionsdarstellung eine Zeigerwelle 1, auf der eine Kappe 2 unverdrehbar angeordnet ist. Diese Kappe 2 hat in ihrer oberen Stirnseite eine durch ihre Mitte führende Nut 3, in die von oben her eine Rinne 4 einsetzbar ist. Diese Rinne 4 besteht aus einem lichtundurchlässigen, lichtreflektierenden Material und hat vorzugsweise eine weiße Färbung. In die Rinne 4 ist von oben her ein Zeiger 5 aus transparentem, lichtleitendem Material einsetzbar. Der Zeiger 5 hat nach unten hin eine Rastnase 6, welche durch einen Durchbruch 7 in der Rinne 4 zu greifen vermag und im montierten Zustand unter eine Rastfläche 8 der Kappe 2 greift.The drawing shows an exploded perspective view of a pointer shaft 1 on which a cap 2 is arranged non-rotatably. This cap 2 has in its upper end face a groove 3 leading through its center, into which a channel 4 can be inserted from above. This channel 4 consists of an opaque, light-reflecting material and is preferably white in color. In the groove 4 is a pointer 5 made of transparent, light-guiding from above Material can be used. The pointer 5 has a catch 6 at the bottom, which is able to grip through an opening 7 in the groove 4 and, in the assembled state, engages under a catch surface 8 of the cap 2.

Bei der Montage des Anzeigeinstrumentes wird der Zeiger 5 von oben her in die Rinne 4 eingeschoben und dann diese Baueinheit ebenfalls von oben her in die Nut 3 gesetzt. Dabei verrastet die Rastnase 6 mit der Rastfläche 8 und hält auf diese Weise den Zeiger 5 und zugleich die Rinne 4 auf der Kappe 2.When mounting the display instrument, the pointer 5 is inserted into the groove 4 from above and then this assembly is also inserted into the groove 3 from above. The latch 6 latches with the latch surface 8 and in this way holds the pointer 5 and at the same time the groove 4 on the cap 2.

Claims (4)

An indicator instrument with a transparent, light-transmitting pointer (5) which is fastened on to a cap (2) of a pointer shaft (1) in such a way that the pointer (5) is inserted into the cap (2) from the end face of the cap and is fastened within the latter by means of a clip attachment, characterised in that the pointer (5) is inserted over substantially its entire length into a channel (4) made of a material which is opaque to light and which reflects light towards the pointer (5).
  2. An indicator instrument according to claim 1, characterised in that the channel (4) is constructed as one piece with the cap (2).
  3. An indicator instrument according to one of the preceding claims, characterised in that the channel (4) can be inserted in a slot (3) in the end face of the cap (2).
  4. An indicator instrument according to one of the preceding claims, characterised in that the pointer (5) has at least one catch projection (6) which can be guided through an opening (7) in the channel (4) and locked with a locking surface (8) of the cap (2).
