Description
Die Erfindung bezieht sich auf eine Tastatur für eine Eingabeeinheit, bestehend ausThe invention relates to a keyboard for an input unit, consisting of
einer Deckfolie,a cover film,
einem Trägermaterial,a carrier material,
einer Trägerplatine unda carrier board and
Mittel zur Beleuchtung der Tasten.Means for illuminating the keys.
Tastaturen der eingangs genannten Art sind bereits aus dem Stand der Technik bekannt, sie werden allgemein als Folientastaturen bezeichnet.Keyboards of the type mentioned above are already known from the state of the art; they are generally referred to as membrane keyboards.
Um eine Beleuchtung der Tasten zu ermöglichen, kann z. B. eine Lumineszenzfolie eingesetzt werden. Diese erzeugt ein kaltes Leuchten unterhalb der gewöhnlichen Glühtemperatur . Eine Beschädigung der Folientastatur wird somit verhindert. Das Leuchten wird z.B. durch Strahlung oder Hochspannung erreicht. Beim Einsatz von Dioden, d.h. für jede Taste eine eigene Diode, werden diese jeweils einzeln verdrahtet, was eine recht aufwendige und somit eine kostenintensive Herstellung bedeutet.To illuminate the keys, a luminescent foil can be used. This produces a cold glow below the usual glow temperature. This prevents damage to the membrane keyboard. The glow is achieved using radiation or high voltage, for example. When diodes are used, i.e. a separate diode for each key, these are each individually wired, which means that production is quite complex and therefore expensive.
Der Erfindung liegt die Aufgabe zugrunde, eine Tastatur der eingangs beschriebenen Art zu schaffen, die eine Beleuchtung der Tastatur mit einfachen Mitteln ermöglicht und die kostengünstig herzustellen ist.The invention is based on the object of creating a keyboard of the type described above, which enables the keyboard to be illuminated using simple means and which can be produced inexpensively.
Die Lösung der Aufgabe durch die Erfindung ist dadurch gekennzeichnet, daßThe solution of the problem by the invention is characterized in that
die Tasten (7) als mindestens teilweise durchscheinende und/oder reflektierende Dome ausgeführt sind. Es wird somit der gewünschten Beleuchtungseffekt erzielt. Die Beschriftung (9) kann klar erkannt werden, insbesondere wenn weiterbildungsgemäß die Dome durch die Mittel (4) zur Beleuchtung der Tasten (7) weitgehend vollständig ausleuchtbar ausgeführt sind.the keys (7) are designed as at least partially translucent and/or reflective domes. The desired lighting effect is thus achieved. The lettering (9) can be clearly recognized, particularly if, according to the further development, the domes are designed to be largely completely illuminated by the means (4) for illuminating the keys (7).
Die Mittel (4) zur Beleuchtung der Tasten (7) sind vorteilhafterweise mit der Trägerplatine (3) verbunden. Fortbildungsgemäß sind die Mittel (4) zur Beleuchtung der Tasten (7) auf der Seite der Trägerplatine (3) befestigt, die der Seite, auf der die Tasten (7) angebracht sind, gegenüber liegt. Vorzugsweise sind die Mittel (4) zur Beleuchtung der Tasten (7) in einem Gehäuse untergebracht.The means (4) for illuminating the keys (7) are advantageously connected to the carrier board (3). According to a further development, the means (4) for illuminating the keys (7) are attached to the side of the carrier board (3) which is opposite the side on which the keys (7) are attached. The means (4) for illuminating the keys (7) are preferably accommodated in a housing.
Um beispielsweise die Haptik der Tasten (7) zu verbessern, können die Dome aus transparentem Polyurethan gefertigt werden.For example, to improve the feel of the keys (7), the domes can be made of transparent polyurethane.
Zur Erzeugung des erforderlichen Schaltvorganges ist das Trägermaterial (2) mit Kontaktfedern (6) ausgerüstet, die beim Niederdrücken die elektrische Funktion von Schließern ausführen.To generate the required switching process, the carrier material (2) is equipped with contact springs (6) which, when pressed down, perform the electrical function of closers.
Weiterbildungsgemäß ist vorgesehen, daß das Trägermaterial (2) durchscheinend oder im Bereich der Mittel (4) zur Beleuchtung der Tasten (7) ausgespart ausgeführt ist. Hierdurch wird sichergestellt, daß das Licht von dem Mittel (4) zur Beleuchtung der Tasten (7) bis in den Dom gelangen kann.According to the further development, the carrier material (2) is translucent or is recessed in the area of the means (4) for illuminating the keys (7). This ensures that the light from the means (4) for illuminating the keys (7) can reach the dome.
In den Zeichnungen ist ein Ausführungsbeispiel der erfindungsgemäßen Vorrichtung dargestellt. Die Figur zeigt schematisch einen Schnitt durch eine Taste der Vorrichtung.An embodiment of the device according to the invention is shown in the drawings. The figure shows a schematic section through a button of the device.
Die Figur zeigt einen Teilschnitt durch eine Folientastatur mit einer Deckfolie 1 und beispielhaft einer Taste 7, die als Dom ausgeführt ist. Zwischen dem Trägermaterial 2 und der Deckfolie 1 ist eine Schaumfolie 5 eingebracht, die partiell im Bereich der Taste 7, vorzugsweise rund, ausgespart ist. Alle Folien, also die Deckfolie 1 mit den Tasten 7, das Trägermaterial 2 und die dazwischen eingebrachte Schaumfolie 5, sind auf einer Trägerplatme 3 befestigt. Die Verbindung der einzelnen Folien untereinander wird vorzugsweise durch Kleben erreicht.The figure shows a partial section through a membrane keyboard with a cover film 1 and, for example, a key 7 that is designed as a dome. A foam film 5 is inserted between the carrier material 2 and the cover film 1, which is partially recessed in the area of the key 7, preferably round. All films, i.e. the cover film 1 with the keys 7, the carrier material 2 and the foam film 5 inserted between them, are attached to a carrier plate 3. The connection of the individual films to one another is preferably achieved by gluing.
Das Trägermaterial 2 mit den aufgebrachten Leiterbahnen ist mit Schaltern, sogenannten Kontaktfedern 6, ausgestattet, die genau unterhalb einer jeden Taste 7 angebracht sind. Zur sicheren Betätigung des Schalters, also der Kontaktfeder 6, ist zwischen der Kontaktfeder 6 und dem Taster 7, vorzugsweise in Betätigungsrichtung X der Taste 7, ein Hilfselement 8 eingesetzt.The carrier material 2 with the applied conductor tracks is equipped with switches, so-called contact springs 6, which are attached exactly below each button 7. For the safe actuation of the switch, i.e. the contact spring 6, an auxiliary element 8 is inserted between the contact spring 6 and the button 7, preferably in the actuation direction X of the button 7.
Die Trägerplatine 3 ist ebenfalls im Bereich einer jeden Taste 7 mit Durchbrüchen versehen, unter denen Mittel 4 zur Beleuchtung der Tasten 7 angebracht sind. Diese Mittel 4 sind direkt mit der Trägerplatine 3, z.B. durch Löten, verbunden. Als Mittel 4 zur Beleuchtung der Tasten 7 sind beispielsweise Leuchtdioden vorgesehen.The carrier board 3 is also provided with openings in the area of each key 7, under which means 4 for illuminating the keys 7 are mounted. These means 4 are connected directly to the carrier board 3, e.g. by soldering. Light-emitting diodes, for example, are provided as means 4 for illuminating the keys 7.
Das Licht kann in diesem Ausfuhrungsbeispiel von der Unterseite der Trägerplatine 3, also von der Diode 4, durch den Durchbruch in der Platine 3 über das durchscheinend ausgeführte Trägermaterial 2 und der partiell durchscheinend ausgeführten Deckfolie 1 bis in den Dom der Taste 7 gelangen. Die Reflektion des Domes gewährleistet, daß die Beschriftung 9 durch den durchscheinend ausgeführten Dom sichtbar ist.In this embodiment, the light can pass from the underside of the carrier board 3, i.e. from the diode 4, through the opening in the board 3, over the translucent carrier material 2 and the partially translucent cover film 1, to the dome of the key 7. The reflection of the dome ensures that the inscription 9 is visible through the translucent dome.
Mit der Erfindung ist es möglich, mit einfachen Mittel eine Vorrichtung der eingangs beschriebenen Art kostengünstig herzustellen und den gewünschten Beleuchtungseffekt der Tasten zu erreichen.The invention makes it possible to produce a device of the type described above inexpensively and to achieve the desired lighting effect of the keys using simple means.
