Description
Die Erfindung bezieht sich auf eine Tastatur, insbesondere für Rechner, gemäß Oberbegriff des Anspruchs 1, wie sie z. B. als Tastaturen für Rechner/Computer, elektronische Wäge einrichtungen, Teach-in-Tastaturen für Fertigungsautomaten o. ä. Verwendung findet.The invention relates to a keyboard, in particular for computers, according to the preamble of claim 1, as z. B. as keyboards for computers / electronic weighing equipment, teach-in keyboards for production machines or the like is used.
Solcherart Tastaturen oder Tastenfelder sind beseis in den unterschiedlichsten Ausführungen bekannt.Such keyboards or keypads are known in the different designs known.
So ist bekannt, Tastaturen zu verwenden, deren Tastenplatten mit Auschnitten versehen sind, in denen mechanisch betätig bate Tasten angeordnet sind. Abgesehen davon, daß die Tasten selbst bzw. deren Federmechanismus kaputt gehen kann, ist auch die Gefahr der Zerstörung der darunter befindlichen Platine durch über die Tastatur verschüttete Flüsssigkeit vorhanden, auch durch Verschmutzung durch Staub, Feuchtig keit usw.So it is known to use keyboards whose key plates are provided with cutouts in which mechanically operated bate buttons are arranged. Apart from the fact that the buttons itself or its spring mechanism can break is also the danger of destroying those below Circuit board due to liquid spilled on the keyboard present, also due to dust, moisture speed etc.
Auch sind sogenannte Folientastaturen bekannt, bei denen die mechanisch betätigten Tasten über Folien vor Verschmutzungen geschützt sind. Diese Folien sind jedoch nicht ausreichend kratz- und reißfest und sind dann auch optisch nicht beson ders ansprechend. Zudem kann sich die Folie leicht verfär ben.So-called membrane keyboards are also known, in which the mechanically operated buttons over foils from contamination are protected. However, these foils are not sufficient scratch and tear resistant and are then not optically special appealing. In addition, the film can easily change color ben.
Aufgabe der Erfindung ist es, eine Tastatur o. g. Gattung anzugeben, die einfach und sicher in Handhabung und Aufbau ist, dabei in bezug auf ihr Tastenfeld unzerstörbar durch verkratzen oder Verschmutzungen, insbesondere eindringende Flüssigkeiten, ist und zugleich ein jederzeit gut sichtbares tastenfeld bzw. Tasten aufweist und zudem optisch anspre chend wirkt.The object of the invention is a keyboard o. G. genus specify the simple and safe to use and set up is indestructible with respect to your keypad scratching or dirt, especially penetrating Liquids, is and at the same time a clearly visible one has keypad or buttons and also visually appealing works.
Diese Aufgabe wird durch eine Tastatur mit den Merkmalen des Anspruchs 1 gelöst. Vorteilhafte Ausgestaltungen sind in den Unteransprüchen gekennzeichnet.This task is performed by a keyboard with the characteristics of the Claim 1 solved. Advantageous configurations are in the Subclaims marked.
Demgemäß ist die Tastenplatte eine durchgehende Platte ohne Einschnitte, aus lichtdurchlässigem bzw. durchsichtigem Ma terial, in der die Tasten als 3-D-Muster eingelasert sind und bei derdie Tastenplatine eine sogen. Soft-Touch Platine ist, auf der die Tastenplatte aufliegt. Hierdurch wird eine besonders widerstandsfähige Tastatur erhalten, die, inbes. wenn in vorteilhafter Weise die Tastenplatte aus Glas gefer tigt ist, eine hohe Kratzfestigkeit gegeben ist. Auch sind keine Tastenzwischenräume mehr vorhanden, durch die Ver schmutzungen auf die Platine gelangen und die Tastatur ver derben kann.Accordingly, the key plate is a continuous plate without Incisions, made of translucent or transparent size material in which the keys are lasered as a 3-D pattern and where the key board is a so-called Soft-touch board on which the key plate rests. This will create a get particularly resistant keyboard, which, esp. if in an advantageous manner the key plate made of glass high scratch resistance is given. Also are no more key gaps due to the Ver dirt on the board and the keyboard can be crude.
Die Glasplatte ist vorzugsweise mit einer Stärke von ca. 8 mm vorzusehen, so daß bei einem magnetischen Wirkungsabstand der Soft-Touch Platine von ca. 12 mm eine gute Schaltarbeit sichergestellt ist.The glass plate is preferably approximately 8 mm thick to be provided so that at a magnetic working distance the soft-touch circuit board of approx. 12 mm does a good job of switching is ensured.
Von besonderm Vorteil ist die Anordnung von Lichtquelen min destens an einer Plattenseite, vorzugsweise die Anordnung von Leuchtdioden entlang der Längsseiten der Platte, in ei nem jeweiligen Abstand von vorzugsweise ca. 1,5 cm voneinan der, so daß deren Licht seitlich in die Platte eingeleitet wird und sich an den eingelaserten Tasten-Mustern reflek tiert, wodurch diese Muster, also die Tasten im Tastenfeld sehr gut zu erkennen und damit anzutippen sind. Durch die innere Platten- bzw. Tastenbeleuchtung wird ein sehr inter essanter optischer Effekt erzielt, abgesehen davon, daß durch die über den Tasten befindlichen Hände kein Schatten mehr auf die Tasten fällt, diese verdeckend.The arrangement of light sources min at least on one side of the plate, preferably the arrangement of LEDs along the long sides of the plate, in egg a respective distance of preferably about 1.5 cm from each other the so that their light is introduced laterally into the plate will and reflect on the lasered key patterns tiert, whereby this pattern, i.e. the keys in the keypad are very easy to recognize and to touch. Through the inner panel or key lighting becomes a very inter produces an essential optical effect, apart from the fact that no shadow due to the hands above the keys falls more on the keys, hiding them.
Vorteilhaft wirkt sich auch aus, wenn die Tastenplatte an ihrer Unterseite mit einer Dunkelfolie oer undurchsichtigen Farbe abgedeckt ist, so daß ein neutraler Hintergrund vor handen ist und zudem die Platine nicht im Sichtfeld stört.It also has an advantageous effect when the key plate is on its underside with a dark film or opaque Color is covered, leaving a neutral background in front is available and also does not interfere with the circuit board in the field of vision.
Schließlich ist auf der Oberseite der Tastenplatte eine Ab deckplatte aufliegend vorgesehenn, die einen zentrischen Fensterauscschnitt besitzt, der das Tastenfeld bzw. die Ta sten freiläßt, jedoch Plattenrand und Gehäuse in dem Platine und Platte mit Beleuchtung angeordnet sind, ausreichend weit abdeckt, bzw. verdeckt. Dabei kann die Dekor-Abdeckplatte aus unterschiedlichstem Material (Metall, Holz, Kunststoff, Marmor ect.) gefertigt sein und die unterschiedlichsten Formgebungen aufweisen (rund, oval, rechteckig, vieleckig, flach, gewölbt, gewellt. . .).Finally there is an Ab on the top of the key plate Provide a cover plate lying on top that has a central one Has window section that the keypad or the Ta Most free, however, the plate edge and housing in the board and plate with lighting are arranged sufficiently far covers or conceals. The decorative cover plate made of different materials (metal, wood, plastic, Marble ect.) And the most varied Shapes (round, oval, rectangular, polygonal, flat, curved, wavy. , .).
Nachfolgend wird die Erfindung anhand von Ausführungsbei spielen unter Bezug auf die Zeichnung näher erläutert. Es zeigt:The invention will now be described with reference to embodiments play explained with reference to the drawing. It shows:
Fig. 1 eine Draufsicht auf eine Tastatur in rechteckiger Ausführung, Fig. 1 is a plan view of a keyboard in rectangular design,
Fig. 2 einen Schnitt II-II aus Fig. 1, insbes. den Innen aufbau zeigend, und Fig. 2 shows a section II-II of Fig. 1, in particular. The interior structure showing, and
Fig. 3 eine Draufsicht wie in Fig. 1, jedoch auf eine Ta statur in ovaler Ausführung. Fig. 3 is a plan view as in Fig. 1, but on a Ta stature in an oval design.
Wie insbes. aus Fig. 1 ersichtlich ist, läßt die erfindungs gemäße Tastatur 1 ein Tastenfeld 2 erkennen, in dem Tasten 3 zu sehen sind und das von einer Dekor-Abdeckplatte 4 mit ei nem Fensterausschnitt 5 umgeben ist. In unterbrochen Linien ist desweiteren erkennbar, wie der ääußere Rand bzw. Umfang 7 der Tastenplatte 6 vom innerren Fensterrand des Abdeck platte unsichtbar abgedeckt ist. Auch ist die rechteckige Form eines Gehäuses 8 angedeutet, an dessen Längs-Innen wänden Leuchtdioden 9 angeordnet sind.As can be seen in particular from FIG. 1, the keyboard 1 according to the invention reveals a keypad 2 in which keys 3 can be seen and which is surrounded by a decorative cover plate 4 with a window cutout 5 . In broken lines it can also be seen how the outer edge or circumference 7 of the key plate 6 is invisibly covered by the inner window edge of the cover plate. The rectangular shape of a housing 8 is indicated, on the longitudinal inner walls of which light-emitting diodes 9 are arranged.
Aus Fig. 2 ist ersichtlich, daß im Gehäuse 8 eine Soft-Touch Platine 11 über einen Sockel 12 eingestellt ist. Auf der Platinenoberseite liegt die Tastenplatte auf, die an ihrer Unterseite mit einer Dunkelfolie 10 versehen ist. Auf der Oberseite der Tastenplatte 6 liegt wiederum die Dekorplatte 4 so auf, daß deren Fensterausschnitt das Tastenfeld bzw. die in der Glas-Tastenplatte 6 eingelaserten Tasten 3 von oben einsehbar freiläßt. E ist zu erkennen, daß die Tasten 3 im wesentlichen höhenmittig in der Platte 6 eingezeichnet sind, über 3-D-Laser-Ausarbeitung. In Höhe der Tastenplatte sind über Halterungen 13 die Leuchtdioden 9 so befestigt, daß ihr Licht in das Platteninnere eingeleitet und an den Tasten 3 reflektiert wird, so daß diese aufleuchten und so von oben im Tastenfeld sehr gut erkennbar sind.From Fig. 2 it can be seen that a soft-touch circuit board 11 is set in the housing 8 via a base 12 . The key plate, which is provided on its underside with a dark film 10 , lies on the top side of the board. On the top of the key plate 6 , in turn, the decorative plate 4 rests in such a way that its window cutout leaves the key field or the keys 3 lasered in the glass key plate 6 exposed from above. It can be seen that the keys 3 are drawn essentially in the center of the height in the plate 6 , via 3-D laser processing. At the level of the key plate, the light emitting diodes 9 are fastened via brackets 13 in such a way that their light is introduced into the inside of the plate and reflected on the keys 3 , so that they light up and can thus be recognized very well from above in the key field.
Fig. 3 zeigt schließlich eine Tastatur 1, bei der eine ovale Abdeckpplatte 4 verwendet wurde, wodurch eine besonderer op tische Wirkung erzielt wird. Fig. 3 finally shows a keyboard 1 , in which an oval cover plate 4 was used, whereby a special op table effect is achieved.
