Description
Zifferblatt für Vierundzwanzigstundenuhren Gegenstand der Erfindung ist ein Zifferblatt für eine Vierundzwanzigstundenuhr, bei welchem in an sich bekannter Weise die Ziffern von i bis 12 und die Ziffern von 13 bis 24 in einem einzigen Kreise angeordnet sind iri der Weise, daß die Verdrehung der Ziffernscheibe um 15' in der einen oder anderen Richtung entweder die Ziffern von i bis i2 oder die von 13 bis 2q. sichtbar gemacht bzw. abgedeckt werden.Dial for twenty-four hour clocks The subject of the invention is a dial for a twenty-four hour clock, in which the digits from i to 12 and the digits from 13 to 24 are arranged in a single circle in a manner known per se, in such a way that the dial is rotated by 15 'in one direction or the other either the digits from i to i2 or those from 13 to 2q. made visible or covered.
Während bei den bisher bekannten Ausführungsformen eines solchen Zifferblattes die Ziffernsicheib.e hinter der Blende drehbar angeordnet ist, wird im Gegensatz hierzu nach der Erfindung eine die Ziffern tragende transparente Scheibe. o. dgl. vor einer mit Feldern verschiedener Helligkeit oder Farbe versehenen Scheibe drehbar angeordnet, so daß bei Wahl geeigneter Farbe oder der Helligkeit der Ziffern je nach Bedarf die Ziffern von i bis 12 vor mit ihnen kontrastierenden Feldern stehen, während die übrigen Ziffern infolge des Fehlens des Kontrastes mit dem Hintergrund unsichtbar werden.While in the previously known embodiments of such a dial the numeralsicheib.e is rotatably arranged behind the cover, is in contrast for this purpose, according to the invention, a transparent disk carrying the digits. or the like rotatable in front of a disc provided with fields of different brightness or color arranged so that depending on the choice of a suitable color or the brightness of the digits If necessary, the digits from i to 12 are placed in front of fields that contrast with them, while the rest of the digits are due to the lack of contrast with the background become invisible.
In Abb. i ist eine solche Anordnung dargestellt, wobei zur Erklärung die schraffierten Felder die vor denselben stehenden Ziffern noch erkennen lassen, während dies in Wirklichkeit nicht der Fall zu sein braucht.Such an arrangement is shown in Fig. I, with explanation the hatched fields still show the digits in front of the same, while in reality this need not be the case.
In Abb.2 ist das die Ziffern tragende transparente Zifferblatt allein dargestellt. Es kann die Anordnung auch so getroffen wer den, , daß ein undurchsichtiges, mit ausgesparten Ziffern versehenes Zifferblatt Verwendung findet, z. B. eine Blech- oder Pappscheibe mit ausgestanzten Ziffern, welche vor einer mit hellen und dunklen Feldern versehenen Scheibe drehbar angeordnet ist, wobei diese Scheibe z. B. eine mit undurchsichtigen Sektoren für die unsichtbar zu machenden Ziffern versehene, von hinten erleuchtete Mattscheibe sein kann. Ebenso kann als Ziffernscheibe das Uhrglas Verwendung finden, während die kontrastierenden Felder auf dem Zifferblatt, welches in diesem Falle keine Ziffern trägt, angebracht sind.In Fig.2, the transparent dial bearing the numbers is alone shown. The arrangement can also be made in such a way that an opaque, dial provided with recessed digits is used, e.g. B. a sheet metal or cardboard disc with punched out digits, which are preceded by one with light and dark Fields provided disc is rotatably arranged, this disc z. Legs provided with opaque sectors for the digits to be made invisible, can be rear-lit screen. It can also be used as a dial Watch glass are used, while the contrasting fields on the dial, which in this case does not have any digits.
