Abstract

The radio watch has a housing of non-metallic material. The components of the watch, its electronics (2), microcontroller (3), receiver (4), long wave antenna (6), clock workings (5) and display unit (8) are surrounded on all sides by parts of the housing (1) and do not represent any components of the housing (1). The long wave antenna (6) itself has no clock-type function elements. The clock face (8) and the antenna (6) are preferably arranged near to each other and the clock face (8) is made of non-metallic material either completely or at least near the antenna (6). The antenna (6) may be a rod antenna and may be arranged in the plane of the watch.

Description

Alle bisherigen Lösungen von Funkarmbanduhren können wie folgt klassifiziert werden:All previous radio wristwatch solutions can be classified as follows:

  • a) Funkarmbanduhren mit einer Langwellenantenne außerhalb des Uhrengehäusesa) Radio wristwatches with a long-wave antenna outside the watch case
  • b) Funkarmbanduhren mit einer Langwellenantenne am Uhrengehäuse oder derart, daß Teile des Gehäuses oder das gesamte Gehäuse aus ferromagnetischem Material bestehen und als Antennenelement genutzt werden.b) radio wristwatches with a long-wave antenna on the watch case or such that parts of the housing or the entire housing made of ferromagnetic material and as Antenna element can be used.
  • c) Funkarmbanduhren, in denen uhrentechnische Baugruppen, z. B. die Platine aus ferro­ magnetischem Material bestehen und als Antennenelement genutzt werden.c) radio wristwatches in which watch-technical assemblies, e.g. B. the board from ferro magnetic material and are used as an antenna element.

Mit diesen Lösungen soll ein möglichst großer Antennengewinn durch maximales Volumen von ferromagnetischem Material in der Antennenanordnung erzielt werden, bzw. groß bauende Antennen außerhalb des Uhrengehäuses möglich sein.These solutions aim to maximize antenna gain through maximum volume of ferromagnetic material can be achieved in the antenna arrangement, or large building antennas outside the watch case may be possible.

Die Schriften G 89 01 512.6, DE 39 41 913 und DE 35 08 366 dokumentieren hierzu den technischen Stand.The documents G 89 01 512.6, DE 39 41 913 and DE 35 08 366 document the technical status.

Nachteilig sind die komplizierten und damit kostenungünstigen ferromagnetischen Teile und eine im magnetischen Sinn nicht optimale Geometrie hinsichtlich des Längen-Durchmesser­ verhältnisses für Ferritantennen. In der DE 35 08 366 und G 88 15 967.1 ist die Antenne im Uhrenarmband eingearbeitet, was Nachteile für die guten Trageeigenschaften und der Wasser­ dichtheit verursacht.The complicated and therefore inexpensive ferromagnetic parts and are disadvantageous a geometry which is not optimal in the magnetic sense with regard to the length diameter ratio for ferrite antennas. In DE 35 08 366 and G 88 15 967.1 the antenna is in Watch strap incorporated, which has disadvantages for the good wearing properties and the water tightness caused.

Lösungen mit gekoppelten Antennen, wie in DE 35 46 471 und G 84 32 848.8 beschrieben, sind für Armbanduhren wegen ihres großen Volumenbedarfs nicht geeignet. Optimale Ergebnisse hinsichtlich eines hohen Antennengewinns, guter Richtcharakteristik und geringer Störanfälligkeit erzielt man mit geraden, stabförmigen Ferritantennen aus reinem Sintermaterial ohne weitere Zusätze, z. B. wie Kunststoffbindungen, bei einem Längen-Durchmesserverhältnis von ca. 5 zu 1.Solutions with coupled antennas, as described in DE 35 46 471 and G 84 32 848.8, are not suitable for wristwatches because of their large volume requirement. Optimal results in terms of high antenna gain, good directional characteristics and low susceptibility to interference is achieved with straight, rod-shaped ferrite antennas pure sintered material without further additives, e.g. B. like plastic bindings at one Length-diameter ratio of approx. 5 to 1.

Die anspruchsgemäße Erfindung ermöglicht den Einbau einer solchen Antenne direkt in ein Armbanduhrgehäuse.The claimed invention enables the installation of such an antenna directly in a Wrist watch case.

In Fig. 1 ist ein Uhrengehäuse entsprechend der Ansprüche dargestellt. Im Inneren des Ge­ häuses 1, welches z. B. aus Kunststoff besteht, sind die Baugruppen Elektronikmodul 2 mit Controller 3 und Empfänger 4, Uhrwerk 5, Langwellenantenne 6 und Batterie 7 angeordnet. Das Uhrenzifferblatt 8 überdeckt die Antenne 6 teilweise.In Fig. 1 a watch case is shown according to the claims. Inside the Ge housing 1 , which, for. B. consists of plastic, the modules electronics module 2 with controller 3 and receiver 4 , clockwork 5 , long-wave antenna 6 and battery 7 are arranged. The watch dial 8 partially covers the antenna 6 .

Die Fig. 2 ist im Maßstab 1 zu 1 gekennzeichnet und zeigt, daß trotz der konventionellen Antennengestaltung eine gute Unterbringung im Uhrgehäuse bei üblicher Gehäusegröße möglich ist. Besonders günstig ist die anspruchsgemäße Anordnung in Verbindung mit einem Langwellenempfänger hoher Eingangsempfindlichkeit. Die Messungen haben gezeigt, daß mit den verfügbaren Empfängerschaltkreisen und der Antenne 6 höhere Empfindlich­ keiten im Vergleich zu bekannten Lösungen erreicht werden. Fig. 2 is marked on a scale of 1 to 1 and shows that despite the conventional antenna design, a good housing in the watch case is possible with a conventional case size. The arrangement according to the claims is particularly favorable in connection with a long-wave receiver with high input sensitivity. The measurements have shown that with the available receiver circuits and the antenna 6 higher sensitivity compared to known solutions can be achieved.
