Description
Kurvenförmig angeordnetes 24-Stundenzifferblatt Zifferblätter mit durchgehender 2q.-Stundenteilung haben den Nachteil, daß sie unübersichtlich sind und beim Ablesen der Zeit leicht Irrtümer entstehen lassen. Zur Beseitigung dieses Nachteils macht man sie mit doppelten Zahlenreihen, mit den Ziffern i bis i2 und 13 bis 2q.. Bei dieser Anordnung ist aber nicht erkenntlich, ob für die augenblickliche Zeit die erste oder zweite Zahlenreihe Geltung hat. Deshalb sind sie auf dem Zifferblatt der vorliegenden Erfindung spiralig angeordnet und der Stundenzeiger durch die Verwendung einer schneckenförmigen Scheibe in seiner Länge veränderlich gemacht und so geführt, daß er auf die gerade geltende Stundenziffer zeigt. Ähnliche Einrichtungen sind schon bekannt, zum Unterschied von diesen ist die Schneckenkurve nicht feststehend, sondern mit halber Geschwindigkeit des Stundenzeigers um die Zeigerachse drehbar gemacht, so daß der Zeiger während des Verlaufs des Tages sich langsam in seiner Länge, der Steigung der Schnecke entsprechend, ändert, bis er mit Ablauf der 2q.. Stunde auf dem Ende der Schnecke angelangt und von einer Feder getrieben in seine Anfangslage zurückspringt. Der Übergang von der höchsten Stelle der Schnecke zur niedersten ist ohne Überschneidung; er verläuft entweder radial oder unter schwacher Vorwärtsneigung, damit der Zeiger eine schwache Dämpfung in seiner Bewegung erhält.Curved 24-hour dial with dials continuous 2q. hour division have the disadvantage that they are confusing and make mistakes easily when reading the time. To eliminate this The disadvantage is that they are made with double rows of numbers, with the digits i to i2 and 13 to 2q .. With this arrangement, however, it is not clear whether for the current Time the first or second row of numbers applies. That's why they're on the dial of the present invention spirally arranged and the hour hand by use a helical disk made variable in its length and guided in such a way, that he points to the currently applicable number of hours. Similar bodies are already known, in contrast to these, the worm curve is not fixed, but can be rotated around the hand axis at half the speed of the hour hand made so that the pointer slowly moves in its position during the course of the day Length, according to the pitch of the screw, changes until it reaches the end of the 2q .. Hour reached the end of the snail and driven by a spring into his Initial position jumps back. The transition from the highest point of the snail to the lowest is without overlap; it runs either radially or under weak Lean forward so that the pointer is slightly dampened in its movement.
