Abstract
Description
Gegenstand der Erfindung ist eine Arbeitsplatte für reversible Brailleschrift.The invention relates to a countertop for reversible Braille.
Reversible Brailleschrift ist für einzelne Braillezeilen (z. B. 8-Punkt-Braille) bekannt.Reversible Braille is known for individual Braille lines (e.g. 8-point Braille).
Deartige Arbeitsplatten mit reversibler Brailleschrift leiden unter dem Nachteil der hohen Fertigungskosten wegen des hohen Montageanteils sowie der durch Verschmutzung beim Ge brauch bedingten häufigen Einsendung der ganzen Braillezeile zum Hersteller zum Zweck der Reinigung.Such countertops with reversible Braille suffer from the disadvantage of high Manufacturing costs due to the high proportion of assembly and contamination due to Ge due to the frequent sending of the whole Braille display to the manufacturer for the purpose of Cleaning.
In der vorliegenden Erfindung ist eine Erweiterung vom Zeilendisplay auf ein Ganzseitendisplay reversibler Brailleschrift vorgesehen:In the present invention is an extension from the line display to a full page display reversible Braille provided:
Durch das Aneinandersetzen mehrerer 8-Punkt-Braillezeilen ergibt sich ein Ganzseitendisplay (gemäß Abb. 1).By placing several 8-point Braille lines together, a full-page display is created (as shown in Fig. 1).
Die Arbeitsplattenstreifen lassen sich durch einfaches Ausklicken vom Benutzer entfernen und bei Verschmutzung durch einen neuen Streifen ersetzen. Der Benutzer kann dann sofort weiter arbeiten und schickt den herausgenommenen Streifen zur Reinigung ein.The worktop strips can be removed by simply clicking and replace with a new strip if dirty. The user can then continue immediately work and send the removed strip for cleaning.
Die Auswechselbarkeit der Arbeitsplattenstreifen bedingt eine Trennung von Arretierung der einzelnen Stifte in der Arbeitsplatte und Antrieb der einzelnen Stifte außerhalb der Arbeits platte:The interchangeability of the worktop strips requires a separation of the locking of the individual pens in the countertop and drive the individual pens outside of work plate:
Gemäß Abb. 2 besteht die Arbeitsplatte zunächst aus der Arbeitsplatte selbst und einer darunter befindlichen Abdeckplatte. Die Abdeckplatte dient dazu, den in der Arbeitsplatte befindlichen und dort gefederten Stift gegenzuhalten. Gleichzeitig dienen die kreuzweisen Schlitze in der Abdeck platte dazu, den Stift beim Setzen und Löschen durch die Kraft F 1 sicher zu führen bzw. beim Löschen aller Stifte einer Zeile durch Verschieben der Abdeckplatte in Richtung X gemäß Abb. 4 alle Stifte dieses Streifens zu löschen.According to Fig. 2, the worktop initially consists of the worktop itself and a cover plate underneath. The cover plate serves to hold the pin located in the worktop and sprung there. At the same time, the crosswise slots in the cover plate serve to securely guide the pin when setting and deleting by the force F 1 or to delete all the pins of this strip when deleting all the pins in a row by moving the cover plate in the direction X according to FIG. 4 .
Der Antrieb zum Setzen oder Löschen der Stifte geschieht zweckmäßig durch eine Kraft F 1 zum Setzen bzw. F 2 zum Löschen gemäß Abb. 2 und 3 durch einen Stempel mit abgeschrägter Phase.The drive for setting or deleting the pins is expediently carried out by a force F 1 for setting or F 2 for deleting according to FIGS. 2 and 3 by a stamp with a beveled phase.
Diese Phase kippt beim Setzen eines Stiftes diesen aus der zeichnerischen Achse, so daß die Kante A′ der Stifte sich über die Kante A′′ der Abdeckplatte schiebt und dort tastsicher arretiert ist.This phase tilts when setting a pin this from the drawing axis, so that the edge A 'of the pins pushes over the edge A''of the cover plate and is locked in place there.
Die Realisierung der Antriebskräfte F 1 und F 2 ist z. B. möglich durch einen Antrieb nach dem Nadeldruckprinzip.The realization of the driving forces F 1 and F 2 is e.g. B. possible by a drive according to the needle pressure principle.
Eine einfachere Form des Antriebs ist möglich durch einen Schlitten (7) gemäß Abb. 5, auf dem stehend Piezostreifen angebracht sind, hier parallel zur Stiftachse, die bei Anlegen einer Span nung (8.1) eine Kraft auf den Stift in Richtung X ausüben und ihn dabei setzen und arretieren.A simpler form of drive is possible through a slide ( 7 ) according to Fig. 5, on which standing piezo strips are attached, here parallel to the pin axis, which exert a force on the pin in direction X and apply it when voltage is applied ( 8.1 ) sit and lock.
Eine weitere Form des Antriebs mit stehenden Piezostreifen (parallel zur Stiftachse) ist ein Piezostreifenkamm (7) der Abb. 5, der in Y-Richtung bewegt wird und bei dem die einzelnen Piezostreifen vor Erreichen eines zu setzenden Stiftes ausgelenkt werden und so mit der Stirn kante gegen die Stiftphase drücken und den Stift setzen oder löschen. Another form of drive with standing piezo strips (parallel to the pin axis) is a piezo strip comb ( 7 ) of Fig. 5, which is moved in the Y direction and in which the individual piezo strips are deflected before reaching a pin to be set and thus with the forehead Press the edge against the pen phase and insert or delete the pen.
In ähnlicher Weise geschieht das Setzen oder Löschen durch liegende Piezostreifen oder durch schräg gestellte Piezostreifen (z. B. Piezoachse rechtwinklig zur Stiftachse).In a similar way, the setting or deleting is done by lying piezo strips or by inclined piezo strips (e.g. piezo axis perpendicular to the pin axis).
Derartige Piezostreifen werden zweckmäßigerweise mit einer Kuppe versehen aus Kunststoff oder Federblech.Piezo strips of this type are expediently provided with a plastic tip or spring plate.
Wenn sich der Schlitten gemäß Abb. 7 in Pfeilrichtung bewegt, läßt sich vor Erreichen eines Stiftes durch die Schaltkuppe der Piezostreifen auslenken oder nicht, je nachdem, ob ein Stift gesetzt bzw. gelöscht werden soll oder nicht.If the slide moves in the direction of the arrow as shown in Fig. 7, the piezo strip can be deflected or not before reaching a pin, depending on whether a pin is to be set or deleted or not.
