Description

Für Büromaschinen, insbesondere für Schreibmaschinen, verwendete man früher Tasten aus nichtmetallischen Preßmassen. Die Schriftzeichen waren .entweder aufgemalt oder eingraviert. Diese Tasten hatten den Nachteil, daß sich die Zeichen bald abgriffen, wodurch die Maschinenbedienung erschwert wurde und die Maschine ein schlechtes Aussehen bekam. Derartige Tasten sind aber auch gegen Handschweiß nicht beständig und deshalb unhygienisch. Sie ließen sich aber leicht auf den Tastenhebeln befestigen, weil der zur Verwendung gekommene Werkstoff elastisch ist.One used for office machines, especially for typewriters earlier keys made of non-metallic molding compounds. The characters were ... either painted on or engraved. These keys had the disadvantage that the characters soon tapped, making machine operation difficult and the machine got a bad look. Such buttons are also against hand sweat not permanent and therefore unhygienic. But they could easily be put on the button levers because the material used is elastic.

Zur Beseitigung der Nachteile entwickelte man Tasten mit bedruckten Papierplättchen, Glasplättchen und Randringen. Diese Tasten haben den Vorteil, daß der die Tasten anschlagende Finger eine Führung erhält, daß dass Deckgläschen die Stoßwärme ableitet und daß sie hygienisch sind, insbesondere dann, wenn Celluloidtastenringe verwendet werden. Nachteile sind, daß sich die Zeichenplättchen drehen und leicht vergilben und der Randring beim Schreiben stört. Außerdem läßt sich der auf den Tasten sich ablagernde Staub nur schwer entfernen. Auch diese Tasten geben den Schreibmaschinen bald ein schlechtes Aussehen. Außerdem ist die Befestigung der Tasten auf den Tastenhebeln erschwert. Diese Mängel zu beseitigen ist der Zweck dieser Erfindung. In der Zeichnung ist der Erfindungsgegenstand beispielsweise dargestellt, und zwar zeigen die Abb. i und a eine Taste im Schnitt und in Draufsicht.In order to eliminate the disadvantages, printed buttons were developed Paper flakes, glass flakes and rings. These keys have the advantage that the finger hitting the keys receives a guide that the cover slip the Dissipates shock heat and that they are hygienic, especially when celluloid key rings be used. Disadvantages are that the drawing plates rotate and easily yellow and the edge ring interferes with writing. In addition, the Keys are difficult to remove deposited dust. These keys also give typewriters looking bad soon. In addition, the buttons are attached to the button levers difficult. To remedy these shortcomings is the purpose of this invention. In the drawing the subject of the invention is shown for example, namely the Fig. i and a a key in section and in plan view.

Die Taste besteht aus einem glasurfähigen Werkstoff, z. B. Porzellan, und ist mit einem Schriftzeichen und Glasur versehen. Mit diesem Werkstoff wird der Erfindungsgedanke am besten gelöst. Die Glasur leitet die Stoßwärme ab. Sie wirkt kühlend auf die anschlagenden Fingerspitzen und ist hygienisch.The button consists of a glaze-compatible material, e.g. B. porcelain, and is provided with a character and glaze. With this material the idea of the invention is best solved. The glaze dissipates the shock heat. she has a cooling effect on the touching fingertips and is hygienic.

Weil dieser Werkstoff aber unelastisch ist, wird in die Bohrung der Taste ein elastischer Werkstoff eingepreßt, welcher wiederum ein Aufpressen der Taste sauf den Tastenhebel zuläßt, ohne daß ein Zerspringen der Taste zu befürchten ist.But because this material is inelastic, the Button pressed in an elastic material, which in turn presses on the Key s on the key lever allows without fear of the key breaking is.
