Abstract

A small radio clock (11), in particular one that can be configured as a wrist watch, is to be equipped, despite the unfavourable spatial conditions, with a receiver antenna (15) of sufficient power. For this purpose, the antenna coil (17) is arranged in the region of at least one side wall of the wrist-watch casing (14), preferably penetrated by an antenna-rod core (16) in the form of a moulding or casting of plastic having embedded ferrite or soft magnetic particles. The core (16) can be constructed as a U- or O-shaped part of the watch casing (14) and accommodate the watch (13) in its interior (20). <IMAGE>

Description

Die Erfindung betrifft eine kleine Funkuhr gemäß dem Oberbegriff des Ansprüches 1. Bei dieser kann es sich um eine Armbanduhr oder um ei­ne sonstwie, etwa an einem Kleidungsstück, getragene Uhr handeln, so­wie beispielsweise um eine kleine Weckeruhr oder um eine kleine Stil­Kaminuhr.The invention relates to a small radio clock according to the preamble of claim 1. This can be a wristwatch or a watch worn in some other way, for example on a piece of clothing, and for example a small alarm clock or a small style fireplace clock.

Die JUNGHANS-Funkuhren in Ausgestaltung als Tisch- oder Wanduhren mit einer Ausstattung, wie in der EP-OS 0 180 155 näher beschrieben ist, haben es rasch zur Marktführerschaft gebracht. Bei kleinen Uhr­en jedoch ist es problematisch, in dem geringen verfügbaren Innen­raum des Uhrengehäuses auch noch eine Langwellen-Antenne ausreichen­der Empfindlichkeit für den Empfang der über Funk übermittelten Tele­gramme unterzubringen. Auch ohne Berücksichtigung dieser speziellen Problematik wurde in der Fachwelt die Verwirklichung einer Funkuhr in der Größenordnung einer Armbanduhr als nicht realistisch angesehen (vgl. R. Bermbach und M. Lobjinski "Neue Funkuhren aus dem Institut für Datentechnik" in FUNKUHREN, herausgegeben von W. Hilberg, Mitte von Seite 170).The JUNGHANS radio-controlled clocks in the form of table or wall clocks with features as described in more detail in EP-OS 0 180 155 have quickly become market leaders. In the case of small clocks, however, it is problematic to also accommodate a long-wave antenna of sufficient sensitivity for the reception of the telegrams transmitted by radio in the small available interior of the watch case. Even without taking this special problem into account, the realization of a radio clock on the order of a wristwatch was not considered realistic by experts (see R. Bermbach and M. Lobjinski "New Radio Clocks from the Institute for Data Technology" in FUNKUHREN, edited by W. Hilberg , Middle of page 170).

Deshalb liegt vorliegender Erfindung die Aufgabe zugrunde, eine kleine (insbesondere auch als Armbanduhr ausgestaltbare) Funkuhr mit aus­reichender Empfangsantenne zu schaffen.It is therefore the object of the present invention to create a small radio clock (which can also be designed as a wristwatch) with a sufficient receiving antenna.

Diese Aufgabe ist erfindungsgemäß im wesentlichen dadurch gelöst, daß die Uhr gemäß dem Kennzeichnungsteil des Ansprüches 1 ausgelegt ist.This object is essentially achieved in that the clock is designed according to the characterizing part of claim 1.

Nach dieser Lösung ist die Antenne nicht mehr, wie bei den marktgängigen Wand- und Tischuhren, gesondert innerhalb des Uhrengehäuses neben der Werkkapsel hinter dem Zifferblatt befestigt. Vielmehr wird nach dieser Lösung eine Antenne unmittelbar in das Uhrengehäuse einbezogen, näm­lich in den Gehäuse-Rand (je nach dem Gehäusematerial auf der Innen­seite oder der Außenseite der Gehäusewand) integriert. Dabei kann eine Antennenspule koaxial zum Gehäuse angeordnet sein, mit Verwendung der ferromagnetischen Teile des Gehäuses und des Werkes als mehr oder we­niger aus dem Spulen-Zentrum heraus in Richtung der wirksamen Feld­komponenten versetzte Bestandteile eines Spulenkerns. Leistungsfähig­ere Antennen jedoch ergeben sich, wenn die Antennenspule unmittelbar von einem nach Maßgabe der Gehäusegestaltung geformten Kern aus Ferrit­pulver oder Weichmagnetpartikeln getragen wird, der in seiner äußeren Kontur den gestalterischen Gehäusevorgaben angepaßt werden kann.According to this solution, the antenna is no longer attached separately inside the watch case next to the movement capsule behind the dial, as is the case with the wall and table clocks on the market. Rather, according to this solution, an antenna is incorporated directly into the watch case, namely integrated into the case edge (depending on the case material on the inside or the outside of the case wall). In this case, an antenna coil can be arranged coaxially with the housing, using the ferromagnetic parts of the housing and the work as components of a coil core which are displaced more or less from the coil center in the direction of the effective field components. However, more powerful antennas result if the antenna coil is carried directly by a core made of ferrite powder or soft magnetic particles which is shaped in accordance with the housing design and whose outer contour can be adapted to the design requirements of the housing.

Zusätzliche Alternativen und Weiterbildungen sowie weitere Merkmale und Vorteile der Erfindung ergeben sich aus den weiteren Ansprüchen und, auch unter Berücksichtigung der Darlegungen in der Zusammenfassung, aus nachstehender Beschreibung von in der Zeichnung unter Beschränkung auf das Wesentliche starkt vereinfacht und nicht ganz maßstabsgerecht skizzierten bevorzugten Realisierungsbeispielen zur erfindungsgemäßen Lösung. Es zeigt:

  • Fig. 1 in Ansicht eine Armbanduhr mit an der Außenseite ihres eigent­lichen Gehäuses angeordneter magnetischer Langwellenantenne,
  • Fig. 2 entsprechend den Gegebenheiten nach Fig. 1 eine Aufteilung der
  • Antenne auf beide Längsseiten des Uhrengehäuses,
  • Fig. 3 in weiterer Abwandlung der Gegebenheiten nach Fig. 1 eine Auf­teilung der Antenne auf zwei winklig zueinander orientierte Gehäuseseiten,
  • Fig. 4 ein Beispiel für den Einbau eines Uhrwerkes in einen exentrisch mit der Spule ausgestatteten Antennenkern,
  • Fig. 5 einen als Antennenkern ausgebildeten Gehäuseboden und
  • Fig. 6 eine Uhr mit konzentrisch zum Werk angeordneter Antennenspule.
Additional alternatives and further developments as well as further features and advantages of the invention result from the further claims and, also taking into account the explanations in the summary, from the following description of the preferred implementation examples which are sketched in a strictly simplified manner and not quite to scale and which are limited to the essentials solution according to the invention. It shows:
  • 1 is a view of a wristwatch with a magnetic long-wave antenna arranged on the outside of its actual housing,
  • Fig. 2 according to the circumstances of Fig. 1 a division of
  • Antenna on both long sides of the watch case,
  • 3 in a further modification of the circumstances according to FIG. 1, a division of the antenna into two housing sides oriented at an angle to one another,
  • 4 shows an example of the installation of a clockwork in an antenna core equipped eccentrically with the coil,
  • 5 shows a housing base designed as an antenna core and
  • Fig. 6 is a clock with an antenna coil arranged concentrically to the work.

Die in Fig. 1 in Draufsicht skizzierte kleine Funkuhr 11 kann mit digitaler oder - wie dargestellt - analoger Zeitanzeige und beispiels­weise als Armbanduhr ausgestaltet sein, also mit Anschluß eines Arm­bandes 12 an ihr das Uhrwerk 13 mit Zeittelegramm-Empfänger aufnehm­endes Gehäuse 14. Die magnetische Antenne 15 weist eine von einem hochpermeablen Kern 16 durchsetzte Spule 17 auf. Im Interesse opti­maler Leistungsfähigkeit der Antenne 15 ist diese in dem oder neben dem Seitenbereich des Uhren-Zifferblattes 18 (für die digitale oder analoge Zeitanzeige) in Richtung der größten Längserstreckung des Gehäuses 14 angeordnet, orientiert quer zur Uhrwerks-(Ziffernwellen-) Achse. Dabei kann die Antennenspule 17 innerhalb des Gehäuses 14 gelegen sein, wenn das Gehäuse 14 - jedenfalls in der Umgebung der Antenne 15 - aus elektrisch nichtleitendem Material besteht. Andern­falls ist die Antenne 15 gemäß Fig. 1 neben dem Zifferblatt 18 außer­halb am Uhren-Gehäuse 14 angeordnet. Dabei kann der Antennen-Kern 16 sich über die Längserstreckung des Gehäuses 14 bis in die Anschluß­bereiche des Armbandes 12 erstrecken, um eine große Länge und damit eine empfindliche Antenne 15 zu realisieren. Abweichend von der Prinzipsskizze der Fig. 1 wird das Gehäuse 14 und der Anschlußbereich des Armbandes 12 dann zweckmäßigerweise so ausgelegt, daß sich eine Gehäuseintegration des Antennenkernes 16 ergibt; wobei es durchaus interessant sein kann, keinen symmetrischen Aufbau zu wählen, um einerseits das Gesamtvolumen der Uhr 11 nicht unnötig zu vergrößern und andererseits werbewirksam darauf hinzuweisen, daß es sich um eine funkgesteuerte Armbanduhr 11 handelt.The small radio-controlled watch 11 sketched in FIG. 1 in top view can be designed with a digital or - as shown - analog time display and, for example, as a wristwatch, that is to say with a bracelet 12 connected to it, the housing 13 receiving the time telegram receiver 14. The magnetic antenna 15 has a coil 17 penetrated by a highly permeable core 16. In the interest of optimal performance of the antenna 15, this is arranged in or next to the side area of the watch dial 18 (for digital or analog time display) in the direction of the greatest longitudinal extent of the housing 14, oriented transversely to the clockwork (numerical wave) axis. The antenna coil 17 can be located inside the housing 14 if the housing 14 - at least in the vicinity of the antenna 15 - consists of electrically non-conductive material. Otherwise, the antenna 15 according to FIG. 1 is arranged next to the dial 18 outside on the watch housing 14. The antenna core 16 can extend over the longitudinal extent of the housing 14 into the connection areas of the bracelet 12 in order to achieve a great length and thus a sensitive antenna 15. 1, the housing 14 and the connection area of the bracelet 12 are then expediently designed in such a way that a housing integration of the antenna core 16 results; whereby it can be quite interesting not to choose a symmetrical structure, on the one hand not to unnecessarily increase the total volume of the clock 11 and on the other hand to advertise effectively that it is a radio-controlled wristwatch 11.

Die Antenne 15 kann aber auch auf zwei Ferrit-Stäbe als den Kernen 16 für Spulen 17 aufgeteilt sein, um eine kleinbauendere Anordnung für die Integration der Antenne 15 zu erzielen. Nach Fig. 2 sind da­bei zwei phasengleich geschaltete Antennenspulen 17 auf zwei Kerne 16 an den beiden Längsseiten des Uhrengehäuses 14 verteilt. Die Stab­kerne 16 können aber auch gemäß Fig. 3 winklig zueinander im oder am Uhrengehäuse 14 (je nach dessen Material) angeordnet und in unter­schiedlichen Längen ausgeführt sein, beispielsweise um die an sich nicht erwünschte Richtcharakteristik einer Ferritstabantenne in Rich­tung auf einen besseren Rundum-Empfang zu beeinflussen (wie im einzelnen in der EP-OS 0 242 717 näher beschrieben).However, the antenna 15 can also be divided into two ferrite rods as the cores 16 for coils 17, in order to achieve a more compact arrangement for the integration of the antenna 15. According to FIG. 2, two antenna coils 17 connected in phase are distributed over two cores 16 on the two long sides of the watch case 14. 3, the rod cores 16 can also be arranged at an angle to one another in or on the watch case 14 (depending on the material thereof) and can be of different lengths, for example in order to improve the directional characteristics of a ferrite rod antenna that are not desired per se in the direction of better all-round reception influence (as described in detail in EP-OS 0 242 717).

Besonders interessante Realisierungsmöglichkeiten in technischer und gestalterischer Hinsicht ergeben sich, wenn gemäß Fig. 4 oder Fig. 5 das Uhrgehäuse 14 selbst als der Antennenkern 16 ausgelegt wird, bei­spielsweise aus Preßstoff mit eingepritzten Ferritkörnern oder Weich­magnetpartikeln ausgebildet ist. Dieser Gehäuse-Kern 16 kann dann in der Draufsicht U-förmig oder gemäß Fig. 4 O-förmig bzw. auch gemäß Fig. 5 als flacher Topf, also mit einem durchgehenden Boden 19 ausge­staltet sein. In jedem Falle nimmt der Innenraum 20 das unter dem Zifferblatt 18 gelegene Uhrwerk 13 auf. Eine einzelne Antenne 17 bzw. eine Mehrzahl davon kann um eine in Richtung der zu empfangenden Funk­feldkomponente 21 sich erstreckende Kern-Verlängerung 22 gewunden sein, vorzugsweise eingelassen in einen als Wickelkörper wirkenden Kern-Einschnitt 23. Die Spule 17 kann aber auch koaxial um eine auf dem Kern-Boden 19 stehende topfförmige Wandung 24 gewickelt sein, wie aus der Querschnittsdarstellung der Fig. 5 ersichtlich, wo der Kern 16 als im Verhältnis zum Durchmesser sehr kurzes Rohrstück auf der dem Zifferblatt 18 abgewandten Seite des Uhrengehäuses 14 ausge­bildet ist. Fig. 6 zeigt eine Anordnung gemäß Fig. 5 in Draufsicht auf das Uhrgehäuse 14; wobei anstelle des im Verhältnis zu seinem Durchmesser sehr kurzen rohrförmigen Kernes (16) auch einfach koaxiale Wicklungen als Antennenspule 17 vorgesehen sein können, wenn nämlich die in Projektion der Feldkomponente 21 innerhalb des Windungsdurch­messers liegenden ferromagnetischen Teile des Werkes 13 und des Gehäuses 14 bereits eine hinreichende Empfangsempfindlichkeit der Antenne 15 erbringen.Particularly interesting realization possibilities from a technical and design point of view arise if, according to FIG. 4 or FIG. 5, the watch housing 14 itself is designed as the antenna core 16, for example is made of pressed material with injected ferrite grains or soft magnetic particles. This housing core 16 can then be U-shaped in plan view or O-shaped according to FIG. 4 or also according to FIG. 5 as a flat pot, that is to say with a continuous bottom 19. In any case, the interior 20 accommodates the clockwork 13 located under the dial 18. A single antenna 17 or a plurality thereof can be wound around a core extension 22 which extends in the direction of the radio field component 21 to be received, preferably embedded in a core incision 23 which acts as a winding body, but the coil 17 can also coaxially around one 5, where the core 16 is formed as a tube piece which is very short in relation to the diameter on the side of the watch case 14 facing away from the dial 18. FIG. 6 shows an arrangement according to FIG. 5 in a top view of the watch case 14; whereby instead of the tubular core (16), which is very short in relation to its diameter, simply coaxial windings can also be provided as the antenna coil 17, if the ferromagnetic parts of the work 13 and the housing 14 that are within the winding diameter in the projection of the field component 21 are already sufficient Provide reception sensitivity of the antenna 15.
