Abstract

In the case of key heads for key panels, a large operating surface should be given on the one hand, but, on the other hand, also sufficient distance between the key heads should also be given in order to avoid operating errors due to fingernails and the like. For this purpose, the invention provides a square baseplate (1) on which a disc-like truncated cone of transparent material is applied, the surface of the truncated cone (3) being domed inward in the manner of a sphere. Between the truncated cone (3) and the baseplate (1), a symbol plate (2) is located for lettering purposes. A key head according to the invention is particularly suitable for high-speed keys of data display devices. <IMAGE>

Description

Die Erfindung betrifft einen Tastenkopf für Schnellschreibtasten, insbesondere von Datensichtgeräten.The invention relates to a key head for high-speed keys, in particular for data display devices.

Bei Datensichtgeräten, aber auch bei anderen Einrichtungen der elektrischen Nachrichtentechnik, werden häufig Tastenfelder benötigt, bei denen die einzelnen Tasten neben- und untereinander angeordnet sind. Diese Tastenköpfe dienen neben der Bedienung der Taste häufig auch gleichzeitig für Beschriftungszwecke. Dabei soll das Beschriftungsfeld möglichst so ausgebildet sein, daß eine zweizeilige Beschriftung bis an den Rand ermöglicht wird. Diese Bedingung wird am besten von rechteckigen oder quadratischen Tasten erfüllt. Derart ausgebildete Tastenköpfe haben jedoch den Nachteil, daß sehr leicht auch Nachbartasten gleichzeitig mitbetätigt werden können, z.B. durch Fingernägel und dergleichen.With data display devices, but also with other devices of the electrical communication technology, keypads are often required, in which the individual keys are arranged next to and below one another. In addition to operating the key, these key heads are often also used for labeling purposes. The labeling field should be designed so that two-line labeling up to the edge is possible. This condition is best met by rectangular or square buttons. However, key heads designed in this way have the disadvantage that neighboring keys can also be actuated at the same time very easily, e.g. by fingernails and the like.

Aufgabe der vorliegenden Erfindung ist es, einen Tastenkopf für Schnellschreibtasten zu schaffen, der neben optimalen Bedingungen für eine eventuell aufzubringende Schrift auch sicher in der Bedienung ist.The object of the present invention is to provide a key head for high-speed keys which, in addition to op the conditions for a font to be applied are also safe to use.

Zur Lösung dieser Aufgabe wird die Erfindung derart ausgebildet, daß auf einer quadratischen Grundplatte ein als Scheibe ausgebildeter Kegelstumpf mit elliptischer Grundfläche aus durchsichtigem Material aufgebracht ist, daß die Oberfläche dieses Kegelstumpfes kugelförmig nach innen gewölbt ist, und daß zwischen Grundplatte und Scheibe eine Symbolplatte für Beschriftungszwecke liegt.To achieve this object, the invention is embodied in such a way that a truncated cone with an elliptical base made of transparent material is formed on a square base plate, that the surface of this truncated cone is spherically curved inwards, and that between the base plate and the disc there is a symbol plate for labeling purposes lies.

Durch diese Ausbildung wird eine fast rechteckförmige Beschriftungsfläche erhalten, wobei jedoch der Abstand der Tastenköpfe voneinander einen entsprechenden Sicherheitsabstand gewährleistet, so daß ein sicheres Bedienen des Tastenfeldes auch bei rasch aufeinanderfolgenden Bedienvorgängen sichergestellt ist. Trotz des Verlaufes der Oberfläche der Ellipse nach unten in Kugelform bleibt noch genügend Raum für die darunter liegende quadratische Symbolplätte. Der Tastenkopf ist gleichzeitig der Form des Fingers optimal angepaßt.This design provides an almost rectangular lettering surface, but the spacing of the key heads from one another ensures a corresponding safety distance, so that safe operation of the keypad is ensured even during rapidly successive operations. Despite the spherical shape of the surface of the ellipse downwards, there is still enough space for the underlying square symbol plate. The button head is also optimally adapted to the shape of the finger.

Anhand der Ausführungsbeispiele nach den Figuren 1 und 2 wird die Erfindung näher erläutert.

  • Fig. 1 zeigt mehrere neben- und untereinander liegende Tasten, die zu einem Tastenfeld zusammengeführt sind-,
  • Fig. 2 zeigt in Draufsicht, Seitenansicht und Vorderansicht einen einzelnen Tastenkopf.
The invention is explained in more detail using the exemplary embodiments according to FIGS. 1 and 2.
  • Fig. 1 shows several keys lying next to and below one another, which are brought together to form a keypad,
  • Fig. 2 shows a top view, side view and front view of a single key.

Das Tastenfeld nach Figur 1 weist eine große Bedien- und Beschriftungsfläche a in Y-Richtung auf, gleichzeitig aber auch einen großen Abstand b in X-Richtung, wodurch das Mitreißen der nächsten Taste durch den Fingernagel vermieden wird.The keypad according to FIG. 1 has a large operating and labeling area a in the Y direction, but at the same time also a large distance b in the X direction, as a result of which the next key is avoided by the fingernail.

Ein einzelner Tastenkopf ist in Figur 2 dargestellt. Auf der quadratischen Grundplatte 1 sitzt ein scheibenförmig ausgebildeter Kegelstumpf 3, der aus durchsichtigem Material ausgeführt ist. Unter diesem Tastenkopf ist eine fast quadratische Symbolplatte 2, die Beschriftungszwekken dient, angeordnet. Tastenkopf mit rechteckiger Grundplatte, auf dem eine kegelstumpfförmige Scheibe, deren Oberfläche kugelförmig nach innen gewölbt ist, aufgebracht ist und die mit einer Symbolplatte unterlegt ist.A single button head is shown in Figure 2. On the square base plate 1 sits a disc-shaped truncated cone 3, which is made of transparent material. An almost square symbol plate 2, which serves for labeling purposes, is arranged under this button head. Key head with a rectangular base plate, on which a frustoconical disc, the surface of which is spherically curved inwards, is applied and which is underlaid with a symbol plate.
