Description

In der Anmeldung P 38 11 406.2 wird eine vorteilhafte Lagerung eines piezo­ keramischen Biegestreifens beschrieben, bei der dieser Streifen an zwei Stellen in schneidenartigen Lagern gelagert wird, wobei durch den Abstand a zwischen den Schneidenpaaren 3 und 4 die Federrate des Biegestreifens optimal ausgelegt werden kann.In the application P 38 11 406.2 an advantageous storage of a piezo ceramic bending strip described in which this strip in two places is stored in knife-like bearings, the distance a between the cutting pairs 3 and 4 optimally designed the spring rate of the bending strip can be.

Eine Verbesserung wird in der Figur dargestellt: Das Trägermaterial wird, wie bereits beschrieben, an den Schneiden 4 gelagert, doch wird für die zweite Lagestelle 3 kein einheitliches Schneidenlager mehr aufgebaut. Vielmehr wird der Biegestreifen an unterschiedlichen Stellen abgestützt, beispielsweise auf einer Seite durch die Aufnahme 31 und auf der anderen Seite durch die Auf­ nahme 32, die näher an die Lagestelle 4 herangerückt wird. Durch diese Auf­ teilung lassen sich die Lagerkräfte noch günstiger gestalten, vor allem lassen sich in unterschiedlichen Bewegungsrichtungen unterschiedliche Kriterien be­ rücksichtigen: Wird z. B. in eine Richtung nur wenig Kraft benötigt, so ist das entsprechende Auflager möglichst nahe an die Lagerstelle 4 heranzurücken, während in der anderen Richtung, in der der Taststift 5 mit höheren Tast­ kräften beaufschlagt wird, die Stützstelle weiter von 4 weggerückt wird. Das für die Montage unbedingt erforderliche Spiel des Biegestreifens erlaubt die Ausnutzung des bei Biegung in Gegenrichtung höheren Weges.An improvement is shown in the figure: The carrier material is, as already described, stored on the cutting edges 4 , but a uniform cutting edge bearing is no longer built up for the second location 3 . Rather, the bending strip is supported at different points, for example on one side by the receptacle 31 and on the other side by the acquisition 32 , which is moved closer to the location 4 . By this division, the bearing forces can be made even more favorable, especially different criteria can be taken into account in different directions of movement: B. only needs little force in one direction, the corresponding support is to be moved as close as possible to the bearing point 4 , while in the other direction, in which the stylus 5 is subjected to higher tactile forces, the support point is moved further away from 4 . The play of the bending strip, which is absolutely necessary for assembly, allows the use of the higher path when bending in the opposite direction.

Vorrichtung zur Darstellung von Blindenschrift, dadurch gekennzeichnet, daß das der Gesamtdicke des Piezo-Streifens entsprechende Schneidenpaar ersetzt wird durch eine untere Auflagerstelle, die weiter von dem anderen Schneiden­ paar entfernt ist, und eine obere Auflagerstelle, die näher an das zweite Schneidenpaar herangerückt ist.Device for displaying Braille, characterized in that the pair of cutting edges corresponding to the total thickness of the piezo strip is replaced by a lower bearing point, which is further away from the other cutting edge pair, and an upper bearing point, which has moved closer to the second pair of cutting edges.
