Description
Die Erfindung betrifft eine Tastatur für elektrotechnische Geräte, insbesondere Kommunikations-Endgeräte nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a keyboard for electrical engineering Devices, especially communication devices according to the Preamble of claim 1.
Bei der in der Hauptanmeldung beschriebenen Tastenanordnung sind die lamellenartig ausgebildeten Betätigungszungen der jeweiligen Tastenfunktion entsprechend beschriftet. Hierzu kann ein einfaches preiswertes Druckverfahren angewendet werden. In Abhängigkeit vom gewählten Druckverfahren und von der Qualität der verwendeten Farbe kann bei häufig be tätigten Tasten eine Abnutzung der Beschriftung auftreten so daß diese nach einiger Zeit nicht mehr gut zu erkennen ist.With the key arrangement described in the main application are the lamellar control tongues of the each button function labeled accordingly. For this a simple inexpensive printing process can be applied will. Depending on the selected printing process and on the quality of the color used can often be If the keys are pressed, the labeling will wear out so that after some time they can no longer be recognized is.
Die Aufgabe der in dieser Zusatzanmeldung beschriebenen Er findung besteht darin, eine Tastatur für elektrotechnische Geräte, insbesondere Kommunikations-Endgeräte, wie sie im Hauptpatent beschrieben ist, so zu verbessern, daß auch bei abgenutzten Tastaturen eine Beschriftung noch einwandfrei zu erkennen ist.The task of the He described in this additional application invention is a keyboard for electrical engineering Devices, in particular communication terminals, as they are in Main patent is described to improve so that at worn keyboards a lettering still perfectly can be seen.
Zur Lösung dieser Aufgabe sind Merkmale vorgesehen, wie sie im Patentanspruch 1 angegeben sind. Damit wird in vorteil hafter Weise erreicht, daß bei einem Verschleiß der für den Aufdruck verwendeten Farbe die Beschriftung trotzdem noch einwandfrei erkennbar ist.To solve this problem, features are provided as they are specified in claim 1. This will be advantageous achieved in such a way that when the Color still used the lettering is perfectly recognizable.
Ein Ausführungsbeispiel der Erfindung wird nachfolgend an hand von Zeichnungen näher beschrieben.An embodiment of the invention is described below hand described in more detail by drawings.
Es zeigt:It shows:
Fig. 1 Einen Ausschnitt aus einer Tastenanordnung mit einer einfachen Nut in der Beschriftung Fig. 1 shows a section of a button arrangement with a simple groove in the label
Fig. 2 Eine Schnittzeichnung entsprechend Fig. 1 FIG. 2 is a sectional drawing corresponding to FIG. 1
Fig. 3 Einen Ausschnitt aus einer Tastenanordnung mit einer der Kontur der Bezeichnung folgenden umlaufenden Nut Fig. 3 shows a section of a button arrangement with a circumferential groove following the contour of the designation
Fig. 4 Eine Schnittzeichnung entsprechend Fig. 3 In der Fig. 1 ist beispielhaft ein Teil einer Ziffern tastatur dargestellt. Der jeweiligen Beschriftung 1 folgend ist eine Nut 2 in der Mitte des Schriftzuges in die Bedien oberfläche 3 eingebracht. Beim Aufdrucken der Beschriftung 1 tritt ein Teil der verwendeten Farbe in diese Nut 2 ein. Wenn durch häufige Benutzung sich die Farbe abnutzen sollte, so daß die Beschriftung 1 nicht mehr deutlich zu erkennen wäre, so geben die in der Nut 2 verbleibende Farbreste dennoch die Bezeichnung wieder. Sollten in der Nut befindlichen Farbreste ebenfalls im Laufe der Zeit teilweise verschwinden, so ist davon auszugehen, daß sich Staubartikel in der Nut ansammeln, so daß dadurch auch dann noch die Beschriftung erkennbar wäre. Fig. 4 A sectional drawing corresponding to Fig. 3 In Fig. 1, part of a numeric keyboard is shown as an example. The respective inscription 1 is followed by a groove 2 in the middle of the lettering in the operating surface 3 . When the inscription 1 is printed, part of the color used enters this groove 2 . If the color should wear off due to frequent use, so that the inscription 1 could no longer be clearly recognized, the color residues remaining in the groove 2 nevertheless reflect the designation. If any paint residue in the groove also partially disappears over time, it can be assumed that dust particles will accumulate in the groove, so that the inscription would then still be recognizable.
In der Fig. 2 ist dargestellt, daß die Nut 2 jeweils in der Mitte einer aufgedruckten Beschriftung 1 in die Bedien oberfläche 3 eingearbeitet ist. Im Beispiel ist ein drei ecksförmiger Querschnitt der Nut angegeben. Es können je doch auch andere Querschnitte vorgesehen sein, wenn dies bei der Herstellung Vorteile bringt.In Fig. 2 it is shown that the groove 2 is incorporated in the middle of a printed label 1 in the operating surface 3 . In the example, a three corner-shaped cross section of the groove is given. However, other cross sections can also be provided if this brings advantages in the production.
Die Fig. 3 zeigt eine Anordnung, wobei die Nut 2 der je weiligen Kontur einer Beschriftung 1 folgend umlaufend an gebracht ist. Es ergibt sich hierbei, wie zuvor beschrieben worden ist, ebenfalls der Effekt, daß bei einer abgenutzten Beschriftung 2 die Bedeutung einer Taste dennoch einwand frei erkannt werden kann. Fig. 3 shows an arrangement, wherein the groove 2 of the respective contour of a label 1 following is brought around. As has been described above, this also results in the effect that the meaning of a key can nevertheless be correctly recognized when the label 2 is worn.
Bei der in Fig. 4 gezeigten Schnittzeichnung ist zu er kennen, daß der Schriftzug einer Beschriftung 1 durch Zwei Nuten 2 begrenzt ist. Es handelt sich dabei um eine die ge samte Beschriftung umlaufende Nut 2, wie dies aus der Fig. 3 ersichtlich ist.In the sectional drawing shown in Fig. 4 it is known that the lettering of a label 1 is limited by two grooves 2 . It is a ge the entire labeling circumferential groove 2 , as can be seen from FIG. 3.
Claims (2)
daß den Linien einer Beschriftung (1) folgend mindestens eine Nut (2) in die Bedieneroberfläche (3) eingearbeitet ist, welche Druckfarbe oder Staubpartikel aufnehmen kann und das Erkennen der Beschriftung (1) auch dann noch ermöglicht, wenn die Druckfarbe auf der Bedienoberfläche (3) abgenutzt ist.1. Keyboard for electrotechnical devices, in particular communication terminals, whereby an electrical contact is made when a key is pressed on a switch mat arranged in the device in order to thereby issue a command, the user interface of the device having U-shaped outbreaks in each case is equipped at the point where a button is to be located, and the resulting lamella-like actuating tongues are equipped at their free ends with an extension which protrudes into the device and, when a pressure is exerted, touches a dome of a switching mat so that a electrical contact is made within the switch mat, and the actuating tongues are printed on their surface with a designation, characterized according to patent application P 41 16 006.1 ,
that following the lines of an inscription ( 1 ), at least one groove ( 2 ) is worked into the user interface ( 3 ), which printing ink or dust particles can accommodate and also enables the inscription ( 1 ) to be recognized when the printing ink on the user interface ( 3 ) is worn out.
