Description
Die Erfindung betrifft eine Armaturentafel für Kraftfahrzeuge, insbesondere für Militärkraftfahrzeuge, gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a dashboard for motor vehicles, in particular for military vehicles, according to the preamble of claim 1.
Die Armaturentafeln von Kraftfahrzeugen verbreiten oftmals ein insbesondere den Fahrer blendendes und störendes Licht. Bei im Nachteinsatz stehenden Militär- Lastkraftwagen, insbesondere bei solchen mit offenem Fahrergehäuse, stellt eine stark leuchtende Armaturentafel eine akute Gefahr dar, da feindliche Luftaufklärung derartige Lastkraftwagen unverzüglich orten würden.The dashboards of motor vehicles often emit a light that is particularly dazzling and disturbing for the driver. In military trucks used at night, especially those with an open driver's compartment, a brightly lit dashboard represents an acute danger, as enemy air reconnaissance would immediately locate such trucks.
Aus der DE-OS 21 43 307 ist bereits eine gattungsgleiche Armaturentafel bekannt, bei der die Lamellen vor der Armaturentafel oder vor den einzelnen Instrumenten angeordnet sind. Dadurch können die Lamellen leicht verschmutzen und beim Reinigen verbogen werden, sowie gegebenenfalls Klappergeräusche hervorrufen. Insbesondere erfordert ihre Anordnung durch die Haltemittel einen erheblichen Raumbedarf.A similar type of dashboard is already known from DE-OS 21 43 307, in which the slats are arranged in front of the dashboard or in front of the individual instruments. This means that the slats can easily become dirty and bent during cleaning, and can also cause rattling noises. In particular, their arrangement requires a considerable amount of space due to the holding means.
Der Erfindung liegt die Aufgabe zugrunde, eine Armaturentafel für Kraftfahrzeuge der eingangs genannten Art zu schaffen, bei der die Lamellen platzsparend und mit geringem Bauaufwand angeordnet sind.The invention is based on the object of creating a dashboard for motor vehicles of the type mentioned at the beginning, in which the slats are arranged in a space-saving manner and with little construction effort.
Gelöst wird diese Aufgabe nach der Erfindung durch die im Kennzeichenteil des Anspruchs 1 angegebenen Merkmale.This object is achieved according to the invention by the features specified in the characterizing part of claim 1.
Zweckmäßigerweise ist die durchsichtige Lamellenabdeckscheibe mit einer zwischen zwei Glasscheiben angeordneten Flüssigkeitskristallschicht belegt. Dadurch können die Lichtstrahlen beim Durchgang durch die Lamellenabdeckscheibe noch in ihrer Intensität abgeschwächt werden. Eine Anregung für die Anwendung des in Anspruch 2 angegebenen Merkmals gibt die DE- OS 22 46 415.The transparent louvre cover plate is expediently covered with a liquid crystal layer arranged between two glass panes. This allows the intensity of the light rays to be further reduced as they pass through the louvre cover plate. DE-OS 22 46 415 provides a suggestion for the use of the feature specified in claim 2.
Nachfolgend wird anhand der Zeichnung eine Ausführungsform der Erfindung näher erläutert. Es zeigtAn embodiment of the invention is explained in more detail below with reference to the drawing. It shows
Fig. 1 einen Ausschnitt einer Seitenansicht eines Fahrergehäusesund Fig. 1 a section of a side view of a driver housing and
Fig. 2 eine Detailseitenansicht in vergrößerter Darstellung. Fig. 2 shows a detailed side view in an enlarged representation.
Die durchsichte Abdeckscheibe 1 deckt die Armaturentafel des Kraftfahrzeuges 3 ab. Sie besitzt jalousieartig angeordnete, zueinander parallel verlaufende eingelassene Lamellen 2 aus lichtundurchlässigem Werkstoff. Diese lassen das von den Lichtquellen hinter der Armaturentafel ausgehende Licht nur parallel zu den Lamellen 2 in Richtung der Lichtstrahlen 4 austreten, die das Gesichtsfeld des Fahrers 5 treffen.The transparent cover panel 1 covers the dashboard of the motor vehicle 3. It has recessed slats 2 made of opaque material arranged like blinds and running parallel to one another. These allow the light emanating from the light sources behind the dashboard to emerge only parallel to the slats 2 in the direction of the light rays 4 that hit the driver's field of vision 5 .
Da die Winkelstellung α dieser durch die Lamellen 2hindurchtretenden Lichtstrahlen 4 in bezug auf das Lot L derart gewählt, daß die Lichtstrahlen 4 nur einen Raum bis knapp oberhalb der Augenhöhe des Kraftfahrzeugfahrers 5 ausfüllen, ist hierdurch gewährleistet, daß keinerlei störende oder verräterische Lichtstrahlen die Windschutzscheibe 11 durchdringen oder nach oben aus dem entfernten Fahrerhausdach 12 austreten können. Ein feindliches Beobachtungsflugzeug könnte also keine leuchtende Armaturentafel eines solchen Militär- Lastkraftwagens observieren und lokalisieren, da es sich in jedem Falle in dem Bereich 9 befindet, welcher durch die Lichtstrahlen 4 nicht ausgefüllt wird.Since the angular position α of these light rays 4 passing through the slats 2 in relation to the plumb line L is selected such that the light rays 4 only fill a space up to just above the eye level of the motor vehicle driver 5 , this ensures that no disturbing or treacherous light rays can penetrate the windshield 11 or emerge upwards from the remote driver's cab roof 12. An enemy observation aircraft could therefore not observe and locate a luminous dashboard of such a military truck, since it is in any case located in the area 9 which is not filled by the light rays 4 .
Das in Fig. 1 durch den Kreis 10 eingegrenzte Teil ist in Fig. 2 in vergrößertem Maßstab dargestellt und zeigt eine abgewandelte Ausführungsform, bei welcher die durchsichtige Lamellenabdeckscheibe 1, 2 durch zwei Glasscheiben 6 und 7 belegt ist, zwischen denen eine Flüssigkristallschicht 8 angeordnet ist. Letztere zusätzliche Vorrichtung gestattet noch eine Vergrößerung des Winkels α, so daß der Fahrer 5 nicht auf direkt ins Auge auftreffende Lichtstrahlen 4 angewiesen ist, sondern deren Sekundärwirkung beobachten kann, welche von den Flüssigkeitskristallen ausgeht. Auch hierbei ergibt sich ein zwar für den Kraftfahrzeugfahrer kontrastreich erkennbares Signalbild, das jedoch so lichtschwach ist, daß es von keinem tieffliegenden Beobachtungsflugzeug erkannt werden kann.The part delimited by the circle 10 in Fig. 1 is shown on an enlarged scale in Fig. 2 and shows a modified embodiment in which the transparent louvre cover plate 1 , 2 is covered by two glass panes 6 and 7 , between which a liquid crystal layer 8 is arranged. The latter additional device allows the angle α to be increased so that the driver 5 is not dependent on light rays 4 hitting the eye directly, but can observe their secondary effect, which emanates from the liquid crystals. This also results in a signal image that is recognizable by the motor vehicle driver with high contrast, but is so faint that it cannot be recognized by any low-flying observation aircraft.
