Description
BeschreibungDescription
Mechanische Datumsanzeigen zur Anzeige des Monatstages wie z.B. bei Uhren werden üblicherweise auf einem einzigen Zeichenträger aufgebracht, so daß insgesamt 31 verschiedene Zahlen auf dem Zeichenträger vorhanden sein müssen.Mechanical date displays for indicating the day of the month, such as those found on watches, are usually applied to a single character carrier, so that a total of 31 different numbers must be present on the character carrier.
Dadurch ist die auf dem Zeichenträger pro Zahl verfügbare Fläche eingeschränkt mit der Folge, daß die Datumsanzeige relativ klein und damit schlecht lesbar wird.This limits the area available per number on the character carrier, with the result that the date display becomes relatively small and therefore difficult to read.
Einige Uhren haben deswegen eine Lupe über der Datumsanzeige und erzielen damit eine geringfügige Verbesserung.Some watches therefore have a magnifying glass above the date display, thus achieving a slight improvement.
Die im Schutzanspruch angegebene Erfindung verwendet zwei Zeichenträger, so daß an Stelle von 31 Zahlen nur maximal 10 Ziffern auf der zur Verfügung stehenden Fläche aufgebracht werden müssen. Deswegen können die Ziffern bei gleicher zur Verfügung stehender Fläche bis zu dem Faktor 3,1 größer sein.The invention specified in the protection claim uses two character carriers, so that instead of 31 numbers, only a maximum of 10 digits need to be applied to the available area. Therefore, the digits can be up to a factor of 3.1 larger with the same available area.
Eine beispielhafte Realisierung zeigen die Bilder 1 bis 3.Figures 1 to 3 show an example implementation.
Bild 1 und Bild 2 zeigen die um den Kreismittelpunkt drehbaren Ziffernscheiben.Figure 1 and Figure 2 show the dials rotating around the center of the circle.
Bild 1 zeigt die unterste Scheibe mit den Einerstellen. Bild 2 zeigt die darüberliegende Scheibe mit den Zehnerstellen, wobei neben jeder Ziffer oder Leerzeichen ein Fenstervorhanden ist, durch das jeweils eine Ziffer aus der darunterliegenden Scheibe sichtbar ist.Figure 1 shows the bottom disc with the ones digits. Figure 2 shows the disc above with the tens digits, with a window next to each digit or space through which a digit from the disc below is visible.
Bild 3 zeigt die die über den beiden anderen liegende feste Scheibe mit einem Fenster, so daß jeweils zwei Stellen der Datumsanzeige sichtbar sind. Auf der Deckscheibe kann das Ziffernblatt angebracht sein.Picture 3 shows the fixed disc above the other two with a window so that two digits of the date display are visible. The dial can be attached to the cover disc.
Für die Scheiben aus Bild 1 und 2 genügt ein einziger Antrieb, in der Weise, daß nur die unterste Scheibe angetrieben wird und beim Wechseln der Einerstelle von der Ziffer 9 zur Ziffer 0 die darüberliegende Scheibe zur nächstfolgenden Zehnerstelle vorbewegt wird.For the disks in Figures 1 and 2, a single drive is sufficient, in such a way that only the lowest disk is driven and when the ones digit changes from the number 9 to the number 0, the disk above is moved forward to the next tens digit.
Eine andere Form der Realisierung zeigen die Bilder 3, 4 und 5, bei denen die Scheibe mit den Einerstellen über der Scheibe mit den Zehnerstellen liegt. Die Fenster befinden sich dann auf der Scheibe mit den Zehnerstellen. Dabei wird auf der Einer-Scheibe Platz für insgesamt 20 Stellen (Ziffern und Fenster) benötigt. Dadurch ergibt sich gegenüber herkömmlichen Datumsanzeigen immer noch eine maximale mögliche Vergrößerung der Ziffern um den Faktor 1,55.Another form of implementation is shown in Figures 3, 4 and 5, where the disc with the ones digits is above the disc with the tens digits. The windows are then located on the disc with the tens digits. The ones disc requires space for a total of 20 digits (digits and windows). This still results in a maximum possible enlargement of the digits by a factor of 1.55 compared to conventional date displays.
