Keyboard

Die vorliegende Erfindung betrifft eine Tastatur für Kommunikationsendgeräte .The present invention relates to a keyboard for communication terminals.

Die meisten Kommunikationsendgeräte besitzen eine Tastatur, bei welcher die einzelnen Tasten aus einem festen einheitlichen Kunststoffblock bestehen, wobei sich die entsprechenden Symbole für die Taste auf der Oberseite der Taste, der Tastenkappe befinden.Most communication devices have a keyboard in which the individual keys consist of a solid, uniform plastic block, with the corresponding symbols for the key located on the top of the key, the key cap.

Derartig ausgebildete Tastaturen können nur im Hellen benutzt werden. Eine Benutzung im Dunkeln ist nicht möglich.Keyboards designed in this way can only be used in daylight. They cannot be used in the dark.

Aufgabe der vorliegenden Erfindung ist es, eine Tastatur anzugeben, welche auch im Dunkeln eine gute Bedienung ermöglicht. The object of the present invention is to provide a keyboard which enables good operation even in the dark.

Diese Aufgabe wird für eine Tastatur für Kommunikationsendgeräte erfindungsgemäß dadurch gelöst, daß die einzelnen Tasten Lichtquellen beinhalten, mit denen eine mit einem Symbol versehene Fläche neben der Taste beleuchtet wird.This object is achieved according to the invention for a keyboard for communication terminals in that the individual keys contain light sources with which an area provided with a symbol next to the key is illuminated.

Mit der erfindungsgemäßen Tastatur ist auch im Dunkeln eine gute Bedienbarkeit gewährleistet. Die Tasten können einfach als Hohlkörper mit einer Öffnung für den Lichtaustritt hergestellt werden.The keyboard according to the invention ensures good usability even in the dark. The keys can be easily manufactured as hollow bodies with an opening for the light to emerge.

Eine -zweckmäßige Weiterbildung der erfindungsgemäßen Tastatur ist dadurch gekennzeichnet, daß die Oberseiten der Tasten im wesentlichen in der Ebene der Oberfläche des Kommunikationsendgerätes liegen und daß die Lichtquelle eine Fläche bestrahlt, die als eine zur Tastenunterseite hin verlaufende Schräge ausgebildet ist.A practical development of the keyboard according to the invention is characterized in that the upper sides of the keys lie essentially in the plane of the surface of the communication terminal and that the light source irradiates a surface which is designed as a slope running towards the underside of the keys.

GR 99 G 2188GR 99 G 2188

Damit ist eine gute Ausleuchtung der mit dem Symbol versehenen Fläche gewährleistet.This ensures good illumination of the area marked with the symbol.

Die Erfindung wird nachstehend anhand eines in der Zeichnung dargestellten Ausführungsbeispiels näher beschrieben.The invention is described in more detail below with reference to an embodiment shown in the drawing.

Figur 2 eine Seitenansicht des in Figur 1 dargestellten Kommunikationsendgerätes, Figure 2 is a side view of the communication terminal shown in Figure 1,

Figur 3 eine vergrößerte Darstellung der erfindungsgemäßen Tastatur des in Figur 1 dargestellten Kommunikationsendgerätes, Figure 3 is an enlarged view of the keyboard according to the invention of the communication terminal shown in Figure 1,

Figur 5 eine teilweise geschnittene Seitenansicht der erfindungsgemäßen Tastatur.Figure 5 is a partially sectioned side view of the keyboard according to the invention.

Die einzelnen Tasten 1 der erfindungsgemäßen Tastatur sind als Hohlkörper ausgebildet, welche eine Öffnung aufweisen, die zur Vorderseite des Kommunikationsendgerätes, im dargestellten Beispiel eines Mobilfunkgeräts, weisen. Innerhalb des Tastenkörpers kann eine einzelne Lichtquelle angeordnet sein, es kann sich aber auch innerhalb des Hohlkörpers das Ende eines Glasfaserkabels befinden, das von einer zentralen Lichtquelle zu der Taste hingeführt ist.The individual keys 1 of the keyboard according to the invention are designed as hollow bodies which have an opening which faces the front of the communication terminal, in the example shown a mobile phone. A single light source can be arranged within the key body, but the end of a fiber optic cable which is led from a central light source to the key can also be located within the hollow body.

Vor der Taste befindet sich eine mit einem Symbol versehene Fläche 2. Die Symbole können beliebig ausgebildet sein, es können aber auch lediglich Zahlen oder Buchstaben als Symbole verwendet werden.In front of the key there is an area with a symbol 2. The symbols can be of any design, but only numbers or letters can be used as symbols.

GR 99 G 2188GR 99 G 2188

Vorteilhaft ist es, die zu bestrahlende Fläche als eine Schräge auszubilden, um eine optimale Beleuchtung der Fläche 2 zu erzielen.It is advantageous to design the area to be irradiated as a slope in order to achieve optimal illumination of area 2.
