Der Rotor 5 des Generators und die Schwungmasse 4 sind an einem zentralen Drehzapfen 6 befestigt, der in einem Kugellager 7 der Montageplatte 2 drehbar gelagert ist. Der mit Dauermagneten versehene oder entsprechend magnetisierte Rotor 5 ist vom Stator 8 umgeben, der eine Ringspule aufweist. Die beiden Ausgangsklemmen des Generators werden von zwei Federkontakten 9 gebildet, welche im nicht belasteten Zustand schräg nach aussen weisen. Die Montageplatte 2 ist mit einem zum Einklemmen des Moduls im Uhrgehäuse bestimmten Ringflansch 10 versehen.According to FIG. 1, module 1 has one Mounting plate 2 on the top of the Generator 3 and on the underside the flywheel 4 wearing. The rotor 5 of the generator and the flywheel 4 are attached to a central pivot 6, the in a ball bearing 7 of the mounting plate 2 rotatable is stored. The permanent magnet or the magnetized rotor 5 is from the stator 8 surrounded, which has a ring coil. The two output terminals of the generator are made by two spring contacts 9 formed, which in the unloaded state point diagonally outwards. The mounting plate 2 is with one for clamping the module in the watch case provided certain ring flange 10.

    Die Figuren 2 und 3 zeigen ein erstes Ausführungsbeispiel einer Armbanduhr mit einem Modul 1 nach Figur 1. Das Gehäuse dieser Uhr besteht aus einem Gehäusemittelteil 11, der oben durch ein Uhrglas 13 verschlossen ist, und aus einem Boden 12. Ein Uhrwerk 14 wird vom Gehäusemittelteil 11 gehalten und trägt ein Zifferblatt 15. Zwischen dem Uhrwerk 14 und dem Boden 12 ist, im Abstand vom Uhrwerk 14, der Modul 1 angeordnet, welcher auf seiner oberen Seite den Generator 3 mit Rotor 5 und Stator 8 und auf seiner unteren Seite die Schwungmasse 4 aufweist, die mit einer Schraube 4a am unteren Ende des Drehzapfens 6 (Figur 1) befestigt ist.Figures 2 and 3 show a first embodiment a wristwatch with a module 1 Figure 1. The case of this watch consists of a Middle housing part 11, the top through a watch glass 13th is locked, and from a floor 12. A clockwork 14 is held by the middle part 11 and carries a Dial 15. Between movement 14 and the floor 12, at a distance from the clockwork 14, is module 1 arranged, which on its upper side Generator 3 with rotor 5 and stator 8 and on it lower side has the flywheel 4, with a screw 4a at the lower end of the pivot 6 (Figure 1) is attached.

    Wie in Figur 2 gezeigt, ist der Modul 1 mit seinem Ringflansch 10 in einer Ausdrehung 11a des Mittelteils 11 eingesetzt und wird beim Schliessen des Gehäuses durch Einpressen des Bodens 12 in den Mittelteil 11 selbsttätig festgeklemmt. Die Befestigung des Uhrwerks 14 und die Anordnung der Ausdrehung 11a sind so gewählt, dass zwischen dem Uhrwerk 14 und dem Modul 1 ein freier Raum besteht, sodass das Uhrwerk 14 in keiner Weise durch den Modul 1 mechanisch belastet wird. Ebenso befindet sich die Unterseite des Moduls mit der Schwungmasse 4 im Abstand vom Boden 12. Beim Einsetzen des Moduls 1 bzw. beim Verschliessen des Gehäuses mit dem Boden 12 erfolgt selbsttätig die erforderliche elektrische Kontaktierung zwischen den Generatorklemmen und einer aufladbaren Stromquelle, vorzugsweise einer aufladbaren Batterie 16, die in üblicher Weise in einer Ausnehmung des Uhrwerks 14 angeordnet ist. Dabei berührt die eine der Kontaktfedern 9 den an Masse liegenden Pol der Batterie, gewöhnlich den aussen liegenden Pluspol, und die andere Kontaktfeder 9 einen an der Unterseite des Uhrwerks 14 zugänglichen Kontakt, der mit dem anderen Pol der Batterie in leitender Verbindung steht.As shown in Figure 2, the module 1 is with its ring flange 10 in a recess 11a of the Middle part 11 is used and is closed when the Housing by pressing the bottom 12 in the Middle part 11 clamped automatically. The Attachment of the clockwork 14 and the arrangement of the Turning 11a are chosen so that between the Clockwork 14 and module 1 there is a free space, so that the movement 14 in no way through the module 1 is mechanically loaded. There is also the Bottom of the module with the flywheel 4 at a distance from the bottom 12. When inserting module 1 or when Closing the housing with the bottom 12 takes place automatically the required electrical contact between the generator terminals and a rechargeable one Power source, preferably a rechargeable battery 16, which in the usual manner in a recess of the Clockwork 14 is arranged. The one touches the Contact springs 9 the grounded pole of the Battery, usually the external positive pole, and the other contact spring 9 one at the bottom of the Movement 14 accessible contact that with the other Pole of the battery is in conductive connection.

    Bei einer Bewegung der Uhr wird die Schwungmasse 4 des Moduls, und damit der Rotor 3 des Generators in Drehung versetzt, sodass die längs des Umfangs des Rotors befindlichen Magnete vor der Ringspule des Stators 8 bewegt werden, wodurch in bekannter Weise Stromimpulse erzeugt werden, die nach Gleichrichtung zum Aufladen der Batterie 16 dienen. Die erforderliche Elektronik bzw. die erforderlichen elektronischen Komponenten, insbesondere zum Gleichrichten und Stabilisieren des induzierten Stroms oder der Spannung, sind, vorzugsweise auf einer Leiterplatte und/oder einer integrierten Schaltung, im Modul 1 untergebracht, können aber auch in einem Werkhalterring bzw. Gehäusering, der im Beispiel nach den Figuren 6 und 7 gezeigt ist, installiert sein.When the clock moves, the flywheel mass 4 of the module, and thus the rotor 3 of the generator in Rotation offset so that along the circumference of the Magnets located in front of the toroid of the rotor Stator 8 are moved, whereby in a known manner Current pulses are generated after rectification serve to charge the battery 16. The required Electronics or the required electronic Components, especially for rectification and Stabilizing the induced current or voltage, are, preferably on a circuit board and / or an integrated circuit, housed in module 1, can also in a movement holder ring or housing ring, that shown in the example according to FIGS. 6 and 7 is installed.

    Die Figuren 4 und 5 zeigen einen Boden 12, der zu einem zweiten Beispiel einer sonst nicht näher dargestellten Kleinuhr gehört und an seinem nach oben gerichteten Rand eine Ausdrehung 12a aufweist, in welcher der Modul 1 mit seinem Ringflansch 10 eingesetzt ist. Wenn das Uhrgehäuse mit diesem Boden 12 verschlossen wird, wird der Ringflansch 10 des Moduls gegen die Unterseite des Gehäusemittelteils gedrückt und eingeklemmt. Wiederum ist die Anordnung so getroffen, dass die Oberseite des Moduls 1, wo sich Rotor 5, Stator 8 und Federkontakte 9 befinden, einen gewissen Abstand vom Uhrwerk hat. Ebenso hat die Unterseite des Moduls 1, wo sich die Schwungmasse 4 befindet, einen gewissen Abstand zum Boden 12.Figures 4 and 5 show a bottom 12, the for a second example of an otherwise not shown Small clock heard and on his up directed edge has a recess 12a, in which the module 1 with its ring flange 10 is inserted. If the watch case with this bottom 12 is closed, the ring flange 10 of the module pressed against the underside of the middle part of the housing and pinched. Again, the arrangement is like this hit that the top of module 1 where itself Rotor 5, stator 8 and spring contacts 9 are one has a certain distance from the clockwork. Likewise, the bottom has of module 1, where the flywheel 4 a certain distance from the floor 12.

    Im Beispiel nach den Figuren 6 und 7 ist angenommen, dass das nicht dargestellte Uhrgehäuse mit einem inneren Werkhalterring 17 oder Gehäusering versehen ist, der in üblicher Weise das nicht dargestellte Uhrwerk trägt. In diesem Falle hat der Werkhalterring 17 auf der Unterseite eine Ausdrehung 17a, in welcher der Modul 1 mit seinem Ringflansch 10 eingesetzt ist. Wenn das Gehäuse zusammengebaut wird, drückt der Boden mit einem nach oben gerichteten Rand, wie beim Beispiel nach Figur 2, gegen den Ringflansch 10 und klemmt so den Modul 1 fest. Wiederum befindet sich die Oberseite des Moduls 1 mit Rotor 5, Stator 8 und Kontaktfedern 9 im Abstand vom Uhrwerk, und die Unterseite des Moduls 1 mit der Schwungmasse 4 befindet sich im Abstand vom Boden.In the example according to FIGS. 6 and 7 assumed that the watch case, not shown, with an inner movement holder ring 17 or housing ring is provided, which is not in the usual way shown clockwork wears. In this case the Movement holder ring 17 on the underside one turn 17a, in which the module 1 with its ring flange 10 is inserted. When the case is assembled, the floor presses with an upward edge, as in the example according to FIG. 2, against the ring flange 10 and clamps module 1. Again located the top of module 1 with rotor 5, stator 8 and contact springs 9 at a distance from the clockwork, and the Bottom of the module 1 with the flywheel 4 is located yourself at a distance from the ground.

    Im Beispiel nach Figur 8 besteht der Modul 1 aus dem Gehäuseboden 18, der gleichzeitig die Montageplatte bildet, dem Generator 3 mit Rotor 5 und Stator 8 sowie der oberhalb des Generators angeordneten Schwungmasse 4. Im Zentrum des Bodens 18 ist ein Zapfen 19 angeformt oder befestigt, um welchen die beweglichen Teile des Moduls 1, nämlich Rotor 5 und Schwungmasse 4 mittels eines Kugellagers 20 drehbar gelagert sind. Die mit den Klemmen der Ringspule des Stators 8 verbundenen Kontaktfedern 9 sind in diesem Falle so gebogen, dass sie seitlich an der Schwungmasse 4 vorbei schräg nach oben ragen. Dieser Modul 1 mit dem Boden 18 kann direkt in ein Gehäusemittelteil eingepresst werden, wie in Figur 9 am Beispiel einer Armbanduhr gezeigt. Diese Uhr hat ein Gehäusemittelteil 11 mit einer unteren Ausdrehung 11a für den Modul 1, einen Werkhalterring 21 oder Gehäusering, der das Uhrwerk 14 hält, ein Zifferblatt 15 und ein Glas 13. Wiederum hat die Oberseite des Moduls 1 mit der Schwungmasse 4 einen Abstand vom Uhrwerk 14. Die aufladbare Batterie, die wie bei der Uhr nach Figur 2 angeordnet ist, ist nicht gezeigt.In the example according to FIG. 8, module 1 consists of the housing base 18, which is also the mounting plate forms the generator 3 with rotor 5 and stator 8 and the one arranged above the generator Inertia 4. In the center of the bottom 18 is a pin 19 molded or attached around which the movable Parts of module 1, namely rotor 5 and flywheel 4 are rotatably supported by means of a ball bearing 20. With the terminals of the ring coil of the stator 8 connected contact springs 9 are bent in this case that they pass the flywheel 4 laterally protrude diagonally upwards. This module 1 with the bottom 18th can be pressed directly into a middle part of the housing be, as in Figure 9 using the example of a wristwatch shown. This watch has a central housing part 11 a lower recess 11a for module 1, one Movement holder ring 21 or housing ring which holds the movement 14 holds, has a dial 15 and a glass 13. Again the top of the module 1 with the flywheel 4 one Distance from clockwork 14. The rechargeable battery that is arranged as in the clock of Figure 2 is not shown.

    Die beschriebenen Ausführungsformen des Moduls 1 können mit Uhrwerken und Gehäusen unterschiedlicher Bauart direkt kombiniert werden, sofern es sich um standardisierte Gehäuse und Standarduhrwerke handelt, die einen vorgeschriebenen Durchmesser haben.The described embodiments of module 1 can with different movements and cases Design can be combined directly, provided that it is standardized housing and standard movements, that have a prescribed diameter.

    Der Boden kann auch aus Glas bestehen. Anstelle eines durch Einpressen montierbaren Bodens kann auch ein Boden mit Schraubbefestigung vorgesehen sein. Die Stromquelle kann auch ein Kondensator sein. The floor can also be made of glass. Instead of a floor that can be assembled by pressing in can also a floor with screw fastening may be provided. The The current source can also be a capacitor.

    Das Beispiel nach Figur 10 zeigt eine Kleinuhr mit einer einteiligen Gehäuseschale 22, in die unten der Modul 1 mit seinem Ringflansch 10 in eine Ausdrehung 22a eingesetzt ist und welche oben durch ein Glas 13 verschlossen ist. Der Abstand zum darüberliegenden Uhrwerk 14 wird durch einen das Uhrwerk haltenden Werkhalterring bzw. Gehäusering 23 gewährleistet, der gleichzeitig den Ringflansch 10 des Moduls 1 einklemmt. Das Zifferblatt 13 wird am Rand durch einen Höhenring 24 gehalten. Die Schwungmasse 4 des Moduls 1, der wiederum mit Federkontakten 9 versehen ist, befindet sich unten.
