Abstract

Die Erfindung betrifft einen Anzeigemechanismus (1) für ein Uhrwerk einer Armbanduhr bei dem das Drehgestell (2) welches keinen mechanischen Antrieb besitzt und nur durch Gravitation in Bewegung gesetzt wird, über einen Drehpunkt (3) mit dem Uhrwerk (4) verbunden ist, wobei das auf dem Drehgestell (2) montierte Anzeigeelement (5), über vom Drehgestell (2) mechanisch unabhängig angetriebene Zahnräder (6, 7, 8) angetrieben wird.The invention relates to a display mechanism (1) for a movement of a wristwatch in which the bogie (2) which has no mechanical drive and is set in motion only by gravity, via a pivot point (3) with the movement (4), wherein the display element (5) mounted on the bogie (2) is driven by gears (6, 7, 8) driven mechanically independently by the bogie (2).

Description

Die vorliegende Erfindung betrifft einen Anzeigemechanismus für ein Uhrwerk einer Armbanduhr, gemäss dem Oberbegriff des Patentanspruchs 1, insbesondere einen Anzeigemechanismus zur Anzeige von Zeitangaben.The present invention relates to a display mechanism for a movement of a wristwatch, according to the preamble of patent claim 1, in particular a display mechanism for displaying time information.

Der erfindungsgemässe Anzeigemechanismus dient wie jeder bekannte Anzeigemechanismus zum Anzeigen von Zeitangaben in Uhrwerken von Armbanduhren. Die aus dem Stand der Technik bekannten Zeitanzeigen für Armbanduhren geben die Zeitangaben wie Sekunden, Minuten, Stunden, Mondphase, Datum, Wochentage und andere Zeitangaben immer so an, dass Zeit anzeigende Elemente, wie Zeiger, Scheiben oder andere Formen zur Zeitanzeige, sich immer an einem im Uhrwerk feststehenden Drehpunkt oder sich auf einem mechanisch angetriebenen Gestell befinden. Dadurch dass die heute bekannten Anzeigeelemente zur Zeitanzeige immer einen im Uhrwerk feststehenden Drehpunkt der Drehachse oder einen Drehpunkt auf einem mechanisch angetriebenen Drehgestell haben, ergibt sich, dass sich die Zeit anzeigenden Elemente immer an geographisch definierten Positionen im Uhrwerk befinden. Durch diese Gegebenheit ist es den heute bekannten Anzeigen in Armbanduhren nicht möglich, dass Anzeigeelemente wie Zeiger Scheiben oder andere Formen zur Zeitanzeige, sich unabhängig von mechanischem Antrieb, bewirkt nur durch Gravitation, frei im Uhrwerk bewegen können.The display mechanism according to the invention, like any known display mechanism, serves to display time information in movements of wristwatches. The wristwatch time displays known from the prior art always indicate the times such as seconds, minutes, hours, moon phase, date, days of the week, and other times such that time indicating elements such as hands, slices, or other forms for displaying time are always on a fixed in the movement fulcrum or on a mechanically driven frame. The fact that the currently known display elements for displaying time always have a fixed in the movement center of rotation or a pivot point on a mechanically driven bogie, it follows that the time-indicating elements are always at geographically defined positions in the movement. Due to this situation, it is not possible for today's displays in wristwatches that display elements such as pointers discs or other forms for time display, regardless of mechanical drive, only by gravity, can move freely in the movement.

Es ist Aufgabe der vorliegenden Erfindung einen Anzeigemechanismus zu schaffen der es ermöglicht, dass das Zeit anzeigende Element sich an einer unabhängig von mechanischem Antrieb, undefiniert geografischen Stelle im Uhrwerk befinden kann. Die Position an welcher sich das Anzeigeelement im Uhrwerk befindet, wird nur durch die Veränderung der Position des Handgelenks, auf welchem die Uhr befestigt ist, und der damit verbundenen Änderung der Gravitation bestimmt, welche auf dem Drehgestell und dem auf dem Drehgestell befestigten Anzeigeelement wirkt. Der Vorteil des erfindungsgemässen Anzeigemechanismus gegenüber den bekannten Anzeigemechanismen besteht nebst ästhetischen Überlegungen darin, dass das Zeit anzeigende Element, vom Träger durch Änderung der Position des Handgelenkes auf welchem die Uhr befestigt ist, an eine vom Träger gewünschte Position in der Uhr gebracht werden kann, und somit sich andere in der Uhr befindlichen Anzeigen, besser abgelesen werden können. Durch starke Bewegung der am Handgelenk befestigten Uhr, kann das Drehgestell und das darauf montierte Anzeigeelement in starke Rotation versetzt werden was dazu führt, dass das Drehgestell mit dem darauf montierten Anzeigeelement mit vielen Umdrehungen pro Minute um seinen Drehpunkt rotiert.It is an object of the present invention to provide a display mechanism which allows the time indicating element to be located on a clockwork independent of mechanical drive, undefined geographical location. The position at which the display element is in the movement is determined only by the change in the position of the wrist on which the watch is mounted, and the associated change in gravity, which acts on the bogie and the indicator mounted on the bogie. The advantage of the display mechanism according to the invention over the known display mechanisms, in addition to aesthetic considerations, is that the time indicating element can be brought to a position desired by the wearer by changing the position of the wrist on which the watch is mounted in the watch, and Thus, other clocks located in the clock, can be read better. By vigorous movement of the wrist-mounted watch, the bogie and the indicator mounted thereon can be set in strong rotation, causing the bogie with the indicator mounted thereon to rotate at many revolutions per minute about its pivot point.

Im Folgenden wird die Erfindung anhand einer Figur detailliert beschrieben. Es zeigt:In the following the invention will be described in detail with reference to a figure. It shows:

Fig. 1 zeigt die bevorzugte Ausführungsform des erfindungsgemässen Anzeigemechanismus in einer zweidimensionalen Ansicht. Zu erkennen ist ein Drehgestell 2 das sich ohne mechanischen Antrieb und nur durch Gravitation um den Drehpunkt 3, welcher sich am Uhrwerk 4 befindet, dreht.
Das Anzeigeelement 5 ist auf dem Drehgestell 2 montiert und wird über vom Drehgestell 2 mechanisch unabhängig angetriebene Zahnräder (6, 7, 8) angetrieben. Fig. 1 shows the preferred embodiment of the display mechanism according to the invention in a two-dimensional view. Evident is a bogie 2 which turns without mechanical drive and only by gravity about the pivot point 3, which is located on the movement 4.
The display element 5 is mounted on the bogie 2 and is driven by the bogie 2 mechanically independently driven gears (6, 7, 8).
