Abstract

Bei einer Uhr, deren Zeitanzeigeelemente mittels elektromagnetischer Wechselwirkung mit unterhalb des Zifferblatts angeordneten Führungselementen die Zeitanzeige bewirken, ist mindestens ein Zeitanzeigeelement (5) in einem über dem Zifferblatt gebildeten Käfigraum unverlierbar gehalten und so angeordnet, daß die Wechselwirkung zwischen diesem Zeitanzeigeelement und seinem zugeordneten Führungselement sich zumindest auf einen Teilbereich dieses Käfigraums (11) erstreckt. Dadurch besteht die Möglichkeit, die elektromagnetische Wechselwirkung so zu bemessen, daß das Zeitanzeigeelement unter dem wechselnden Einfluß der auf ihn wirkenden mechanischen und elektromagnetischen Kräfte zwischen einer Zeitanzeigeposition und einer freien Bewegungslage innerhalb des Käfigraums wechseln kann, was über den technischen Gebrauchswert der Uhr als Zeitanzeigeelement deren ästhetischen Reiz und auch Spielwert wesentlich erhöht und dem Designer eine Vielzahl neuer Gestaltungsmöglichkeiten eröffnet.

Figure 00000001
In the case of a watch whose time display elements cause the time display by means of electromagnetic interaction with guide elements arranged below the dial, at least one time display element (5) is held captive in a cage space formed above the dial and is arranged in such a way that the interaction between this time display element and its associated guide element increases extends at least to a portion of this cage space (11). This makes it possible to measure the electromagnetic interaction so that the time display element can change under the changing influence of the mechanical and electromagnetic forces acting on it between a time display position and a free movement position within the cage space, what about the technical use value of the watch as a time display element aesthetic appeal and play value significantly increased and the designer opens up a variety of new design options.
