A multi-layer circuit (21) is held under a ceramic support plate. A work capsule (24) with a drive motor for the movement of the hands (16) is held under the support plate near the circuit (21).

Description

Die Anmeldung betrifft eine Uhr gemäß dem Oberbegriff des Anspruches 1.The application relates to a watch according to the preamble of claim 1.

Eine derartige Uhr ist aus der WO 84/02203 bekannt. Dort ist unter dem Rand des Uhrglases eine elektromechanische Schaltstrecke realisiert, für deren Betätigung ein Keil parallel zur Achse der Zeigerwellen verschoben werden muß. Diese Verschiebung erfolgt dadurch, daß oberhalb des Keiles Druck auf den Randbereich des Uhrglases ausgeübt wird, welches gewissermaßen schwimmend mittels einer gummielastischen Halterung in das Uhrengehäuse eingesetzt ist. Diese Lösung der seitlichen Keil-Betätigung einer elektromechanischen Kontaktstrecke ist aber elektrisch nicht besonders zuverlässig und sowohl in radialer als auch in axialer Richtung des Gehäuses sehr raumaufwendig. Außerdem ist eine definierte Lage des Uhrglases im Gehäuse nicht realisierbar, weil der Rand des Uhrglases relativ weit eingedrückt werden können muß, um den Keil für die Kontaktgabe hinreichend weit zu verschieben.Such a clock is known from WO 84/02203. There is an electromechanical switching path under the edge of the watch glass, for its operation a wedge must be moved parallel to the axis of the pointer shafts. This shift takes place in that pressure is exerted on the edge area of the watch glass above the wedge, which is inserted to a certain extent in a floating manner into the watch case by means of a rubber-elastic holder. However, this solution of the lateral wedge actuation of an electromechanical contact path is not particularly reliable electrically and is very space-consuming both in the radial and in the axial direction of the housing. In addition, a defined position of the watch glass in the housing cannot be achieved because the edge of the watch glass must be able to be pressed in relatively far in order to shift the wedge sufficiently far for contact.

In Erkenntnis dieser Gegebenheiten liegt vorliegender Erfindung die technische Problematik zugrunde, eine Uhr gattungsgemäßer Art dahingehend weiterzubilden, daß sie kompakter, insbesondere flacher, realisierbar ist und eine in Hinblick auf die Dichtigkeitsanforderungen zuverlässigere Einfassung des Uhrglases in das Gehäuse ermöglicht.In recognition of these circumstances, the present invention is based on the technical problem of developing a watch of the generic type in such a way that it is more compact, in particular flatter, realizable and enables the watch glass to be more reliably enclosed in the housing with regard to the tightness requirements.

Diese Aufgabe ist erfindungsgemäß im Wesentlichen dadurch gelöst, daß die gattungsgemäße Uhr auch nach dem Kennzeichnungsteil des Hauptanspruches ausgelegt ist.This object is essentially achieved in that the generic watch is designed according to the characterizing part of the main claim.

Nach dieser Lösung mit dem an der inneren Gehäusewandung, zwischen Uhrglas und darunter gelegener Trägerscheibe (für Zifferblatt und Werk der Uhr), angeordneten Piezosensor als Druckschalter wird eine praktische wegfreie Betätigung realisiert, was anstelle der weichelastischen nun eine steifelastische und damit definierte Einfassung des Uhrglases im Gehäuse ermöglicht. Die Anordnung des Piezosensors direkt auf dem Rand der Trägerscheibe eröffnet einfache Möglichkeiten zum elektrischen Anschluß an eine Auswerteschaltung, die exzentrisch auf der vom Uhrglas abgewandten Rückseite der Trägerscheibe befestigt ist.After this solution with the piezo sensor arranged as a pressure switch on the inner case wall, between the watch glass and the underlying support plate (for the dial and movement of the watch), a practical path-free actuation is realized, which instead of the soft elastic means a rigid and thus defined bezel of the watch glass in the Enables housing. The arrangement of the piezo sensor directly on the edge of the carrier disk opens up simple possibilities for electrical connection to an evaluation circuit which is attached eccentrically on the back of the carrier disk facing away from the watch glass.

Um die Trägerscheibe nicht für Brückenfunktionen des Uhrwerkes profilieren zu müssen (wie es aus der EP 0 531 853 A für den Fall einer Ferrit-Werkplatte für eine Funkuhr-Antennenspule bekannt ist), ist das Räderwerk - im Falle einer Funkuhr-Ausbildung einschließlich Zeigerstellungs-Detektoren etwa in Form von Lichtschranken - in eine gesonderte Werkkapsel eingefaßt, die ihrerseits komplett unter die Trägerscheibe montiert ist. Um eine vollautomatische, autark arbeitende Uhr zu schaffen, erfolgt ein solar elektrischer Betrieb der Uhrenschaltung und des Motors zum Antrieb des Werkes aus Fotozellen, deren Siliziumschicht unmittelbar auf eine keramische (vorzugsweise aus Zirkonoxyd oder Aluminiumoxyd bestehende) Trägerscheibe unter dem Uhrglas aufgebracht ist. Das spart Bauhöhe geegnüber der herkömmlichen Applizierung von sparat gefertigten Solarzellen. Auf der Rückseite der Trägerscheibe, neben dem Werk, ist dann ein Pufferspeicher für den Solarstrom angeordnet.In order not to have to profile the carrier disk for bridge functions of the clockwork (as is known from EP 0 531 853 A for the case of a ferrite work plate for a radio clock antenna coil), the gear train is - in the case of a radio clock training including pointer position Detectors, for example in the form of light barriers - enclosed in a separate work capsule, which in turn is completely mounted under the carrier plate. In order to create a fully automatic, self-sufficient clock, the clock circuit and the motor for driving the movement are operated by photovoltaic cells, the silicon layer of which is applied directly to a ceramic (preferably made of zirconium oxide or aluminum oxide) support disc under the clock glass. This saves overall height compared to the conventional application of separately manufactured solar cells. A buffer store for the solar power is then arranged on the back of the carrier disk, next to the factory.

Innerhalb des Uhren-Gehäuses ist neben dem Speicher und der Werkkapsel noch Freiraum zur Aufnahme einer abgestimmten magnetischen Langwellen-Antenne für den Betrieb eines Funkuhr-Empfängers. Im Interesse möglichst großer Länge verläuft deren Kern beiderseits einer Antennenspule gebogen längs der hochzylindrischen Gehäusewandung.In addition to the memory and the work capsule, there is still space inside the watch housing to accommodate a coordinated magnetic long-wave antenna for the operation of a radio-controlled clock receiver. In the interest of the greatest possible length, the core of the antenna runs on both sides of an antenna coil along the highly cylindrical housing wall.

So ist eine extrem flache, vollautomatische Uhr, ohne Durchbrechungen für Bedienungselemente, geschaffen, bei der die Solarzellen unmittelbar auf eine Keramik-Trägerscheibe aufgebracht sind, die gegenüberliegend die weiteren mechanischen und elektrischen Komponenten sowie deren Verschaltung und am Rande praktisch weglos arbeitende Druckschalter trägt, welche längs des Uhrglas-Randes manuell betätigbar sind.This creates an extremely flat, fully automatic watch, with no openings for controls, in which the solar cells are attached directly to a ceramic carrier plate, which is opposite the other mechanical and electrical components and their wiring and practical on the edge carries pressure switches working without a path, which can be operated manually along the edge of the watch glass.

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 eines in der Zeichnung unter Beschränkung auf das Wesentliche stark abstrahiert aber im wesentlichen maßstabsgerecht skizzierten bevorzugten Realisierungsbeispiels zur erfindungsgemäßen Lösung. In der Zeichnung zeigt:

die Armbanduhr gemäß Fig. 1 im Querschnitt.
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 a preferred implementation example sketched in a highly abstracted manner but essentially to scale, limited to the essentials solution according to the invention. The drawing shows:
Fig. 1
an inventive watch in a greatly enlarged axial section and
Fig. 2
1 in cross section.

Als Beispiel für eine erfindungsgemäß ausgestattete flache Uhr ist in der Zeichnung eine Armband-Uhr 11 dargestellt. Deren Garnitur ist als flaches topfförmiges Gehäuse 12 ausgelegt, das sichtseitig durch ein Uhrglas 13 hermetische verschlossen ist. Unter diesem ist in das Gehäuse 12 eine Trägerscheibe 14 eingesenkt, nämlich kraftschlüssig in eine stufenförmigen Verjüngung der im übrigen hohlzylindrischen Innenmantelfläche des Gehäuses 12 eingepaßt. Der Definition eines axialen Zwischenraumes 15, in welchem sich die Zeiger 16 drehen, dient ein längs der Zylinderinnenwandung des Gehäuses 12 umlaufender Bund 17, der sich vom Uhrglas 13 koaxial zur Zeigerwellen-Achse 18 nach unten oder wie dargestellt von der Trägerscheibe 14 nach oben erstreckt. An wenigstens einer Stelle im Verlaufe des Bundes 17 ruht vor seiner Stirnfläche einer flacher Piezosensor 19. Der dient als Betätigungsschalter für die Bedienung der Uhr 11 und wird durch axiales Drücken des darüberliegenden Randbereiches des Uhrglases 13 manuell betätigt. Da dieses unter Zwischenlage eines steifen Gummiringes 20 elastisch in das Gehäuse 12 eingesetzt ist, genügt wegen des praktischen wegfreien Ansprechens des Piezosensors 19 eine minimale Verlagerung des Randes des Uhrglases 13 relativ zum am Gehäuse 12 starr festgelegten Bund 17 für die Aktivierung des Piezosensors 19. Für unterschiedliche Funktionen sind mehrere, wenigstens zwei und vorzugsweise drei oder vier, solcher Piezosensoren 19 peripher gegeneinander versetzt zwischen dem verlagerbaren Rand des Uhrglases 13 und dem feststehenden Rand der Trägerscheibe 14 angeordnet. Über aufkaschierte oder integrierte Leitebahnen (in der Schnittdarstellung der Zeichnung nicht ersichtlich) sind die Piezosensoren 19 an eine Multilayer-Schaltung 21 für u.a. Auswertung der druckabhängigen diskreten (binären) Schaltzustände angeschlossen.A bracelet watch 11 is shown in the drawing as an example of a flat watch equipped according to the invention. Their set is designed as a flat pot-shaped housing 12, which is hermetically sealed on the visible side by a watch glass 13. Under this, a carrier disk 14 is recessed into the housing 12, namely non-positively fitted into a step-like taper of the otherwise hollow cylindrical inner surface of the housing 12. The definition of an axial intermediate space 15, in which the pointers 16 rotate, is served by a collar 17 which runs along the cylinder inner wall of the housing 12 and which extends from the watch glass 13 coaxially to the pointer shaft axis 18 downwards or, as shown, from the carrier disk 14 upwards . A flat piezo sensor 19 rests in front of its end face at at least one point in the course of the collar 17. It serves as an actuation switch for operating the watch 11 and is actuated manually by axially pressing the overlying edge area of the watch glass 13. Since this is inserted elastically into the housing 12 with the interposition of a rigid rubber ring 20, a minimal displacement of the edge of the watch glass 13 relative to the collar 17 rigidly fixed on the housing 12 is sufficient for the activation of the piezo sensor 19 because of the practical, path-free response of the piezo sensor 19 Different functions are several, at least two and preferably three or four, such piezo sensors 19, offset peripherally relative to one another between the displaceable edge of the watch glass 13 and the fixed edge of the carrier disk 14 arranged. The piezo sensors 19 are connected to a multilayer circuit 21 via, for example, evaluation of the pressure-dependent, discrete (binary) switching states via laminated or integrated guideways (not shown in the sectional illustration of the drawing).

Diese Multilayer-Schaltung 21 ist exzentrisch direkt unter die Trägerscheibe 14 montiert, wie aus der Zeichnung ersichtlich. Darunter, also ebenfalls auf der vom Uhrglas 13 abgelegen Seite der Trägerscheibe 14, ruht auf dem Boden 22 des Gehäuses 12 ein elektrophysikalischer oder elektrochemischer Speicher 23. Der dient der elektrischen Versorgung der Mulitlayer-Schaltung 21 und eines aus dieser zeithaltend betriebenen Motors für den Antrieb des Zeigerwerkes, das samt Motor in eine Werkkapsel 24 eingeschlossen ist, welche exzentrisch, neben der Multilayer-Schaltung 21 die Position der Zeigerwellen-Achse 18 überdeckend, unter der Trägerscheibe 14 gehaltert, etwa mechanisch eingerastet ist.This multilayer circuit 21 is mounted eccentrically directly under the carrier disk 14, as can be seen from the drawing. Underneath, ie also on the side of the carrier disk 14 remote from the watch glass 13, an electrophysical or electrochemical memory 23 rests on the bottom 22 of the housing 12 the pointer mechanism, which is enclosed together with the motor in a work capsule 24, which is eccentrically, in addition to the multilayer circuit 21 covering the position of the pointer shaft axis 18, held under the carrier disk 14, approximately mechanically engaged.

Zum Nachladen des Speichers 23 ist die dem Uhrglas 13 zugewandte Oberfläche der Trägerscheibe 14, die innerhalb des Bundes 17 von der Skalierung umgeben ist, mit solarelektrischen Konvertern 25 (sogenannten Solarzellen) ausgestattet. Um den ohnehin schon kompakten Aufbau der Uhr noch flacher ausgestalten zu können, handelt es sich hierbei nicht um diskrete Zellen die auf die Trägerscheibe 14 montiert sind; sondern die Trägerscheibe 14 besteht aus einer elektrischen nichtleitenden und mechanisch sehr stabilen Keramik-Substanz, wie vorzugsweise Zirkon- oder Aluminiumoxyd, welche rückseitig unmittelbar mit den Anschlußleiterbahnen für den Motor in der Werkkapsel 24 und für die Multilayer-Schaltung 21 ausgestattet ist und frontseitig (sichtseitig) unmittelbar mit Silizium für die Solarzellen-Funktion beschichtet ist.To recharge the memory 23, the surface of the carrier disk 14 facing the watch glass 13, which is surrounded by the scaling within the collar 17, is equipped with solar-electric converters 25 (so-called solar cells). In order to make the already compact construction of the watch even flatter, these are not discrete cells which are mounted on the carrier disk 14; but the carrier disc 14 consists of an electrically non-conductive and mechanically very stable ceramic substance, such as preferably zirconium or aluminum oxide, which is directly equipped on the back with the connecting conductor tracks for the motor in the work capsule 24 and for the multilayer circuit 21 and on the front (visible side ) is directly coated with silicon for the solar cell function.

Um die Uhr 11 möglichst bedienungsfreundlich auszugestalten, beinhaltet die Multilayer-Schaltung 21 zweckmäßigerweise auch eine Funkuhren-Funktion mit unmittelbar aufgebondeten Halbleitchips für Empfänger, Demodulator und Auswerteprozessor zur Überprüfung und Korrektur der Zeigerstellung nach Maßgabe aktuell empfangener Zeittelegramme. Als diskrete Bauelemente sind im Gehäuse 12 der Uhr 11 nur noch die Schwingquarze 26 für den Betrieb des abgestimmten Funkuhr-Empfängers und für den Betrieb des Prozessors unterzubringen; sowie eine kleine abgestimmte magnetische Langwellen-Antenne 27. Deren flexibler Kern 28 schmiegt sich bogenförmig entlang der hohlzylindrischen Innenwandung des Gehäuses 12 in den verbleibenden Raum neben der Werkkapsel 24 und dem Speicher 23 (vgl. Fig. 2), und er trägt im mittleren Bereich die an die Schaltung 21 angeschlossene Antennen-Spule 29, die dadurch tangential im Gehäuse 12, parallel zum Uhrglas 13 und zum Gehäuse-Boden 22, orientiert ist.In order to make the clock 11 as user-friendly as possible, the multilayer circuit 21 expediently also includes a radio clock function with directly bonded semiconductor chips for the receiver, demodulator and evaluation processor for checking and correcting the position of the hands in accordance with currently received time telegrams. Only discrete components for the operation of the coordinated radio clock receiver and for the operation of the processor are to be accommodated as discrete components in the housing 12 of the clock 11; such as a small tuned magnetic long-wave antenna 27. Its flexible core 28 nestles in an arc along the hollow cylindrical inner wall of the housing 12 into the remaining space next to the work capsule 24 and the memory 23 (see FIG. 2), and it carries the in the middle area antenna coil 29 connected to the circuit 21, which is thereby oriented tangentially in the housing 12, parallel to the watch glass 13 and to the housing base 22.

Ein elektrooptisches Anzeigeelement 30 kann wie dargestellt unter einer fensterförmigen Durchbrechung der Trägerscheibe 14 in der Werkkapsel 24 vorgesehen sein.As shown, an electro-optical display element 30 can be provided under a window-shaped opening in the carrier disk 14 in the work capsule 24.
