Description
Zifferblatt für Uhren für 24-Stundenzeitangabe. Die Erfindung betrifft ein Zifferblatt für Uhren für 24-Stundenzeitangabe, deren Stundenzeiger in 12 Stunden eine Umdre- hunge macht.
Das Neue besteht darin, dass die Stunden zahlen 1-24 spiralförmig auf dem Ziffer blatt angeordnet sind.
Zwei Ausführungsbeispiele des Erfindungs gegenstandes sind in der Zeichnung darge stellt und zwar zeigt: Fig. 1 ein Zifferblatt auf welchem die Stundenzahlen auf einer Spirale mit zwei Windungen angeordnet sind, welch letztere von aussen nach innen im Drehsinn des Uhr zeigers verlaufen und an denen die Stunden 0-24 so angebracht sind, dass das äussere Ende die Zahl 0 und das innere die Zahl 24 trägt.
Fig. 2 zeigt eine Ausführung bei welcher die Stundenzahlen auf einer Spirale ange ordnet sind, welche im Sinne des Uhrzeigers von innen nach aussen verlaufen. In diesem Fall steht am innern Ende der Spirale die Zahl 0 und am äussern Ende die Zahl 24.
Bei dieser Anordnung findet der Über gang von einer Zahl auf die andere in gleichförmiger stetiger Weise statt, während dieses Merkmal der bisher benutzten Dar stellung der 24 Stundenzahlen auf zwei kon zentrischen greisen fehlt.
Die Art des Ablesens ergibt sich aus der Zeichnung. Am Stand des kleinen Zei gers werden die Stunden und an demjenigen des grossen die Minuten abgelesen.
Dial for watches for 24-hour time indication. The invention relates to a dial for clocks for 24-hour time indication, the hour hand of which makes one revolution in 12 hours.
The new thing is that the hours numbers 1-24 are arranged in a spiral on the dial.
Two embodiments of the subject invention are in the drawing Darge shows: Fig. 1 shows a dial on which the numbers of hours are arranged on a spiral with two turns, the latter extending from the outside to the inside in the direction of rotation of the clock pointer and where the hours 0-24 are attached so that the outer end bears the number 0 and the inner end the number 24.
Fig. 2 shows an embodiment in which the numbers of hours are arranged on a spiral, which run in the clockwise direction from the inside to the outside. In this case, the number 0 is at the inner end of the spiral and the number 24 is at the outer end.
In this arrangement, the transition from one number to the other takes place in a uniform steady manner, while this feature of the previously used Dar position of the 24 hour numbers on two concentric greisen is missing.
The type of reading results from the drawing. The hours are read on the stand of the small hand and the minutes on that of the large hand.
