Description
Stimmgabel als zeitbestimmendes Glied für eine elektrische Uhr Die Erfindung bezieht sich auf eine Stimmgabel als zeitbestimmendes Glied für eine elektrische Uhr. Es kann in diesem Zusammenhang als bekannt vorausgesetzt werden, daß solche Stimmgabeln in elektrischen Uhren ein diese treibendes Schwingglied darstellen, das selbsterregt ist und in seiner Eigenfrequenz durch elektromagnetische Antriebsysteme in Schwingung unterhalten wird. Solche Stimmgabeln sind mittels eines sich in den Raum zwischen ihren über einen Steg verbundenen Zinken erstreckenden Haltearm am Uhrengehäuse festgelegt; mindestens eine ihrer Zinken steht mit einer die Schwingung in eine Drehbewegung umsetzenden übertragungsvorrichtung zum Antrieb des Zeigerwerks mechanisch in Wirkverbindung.Tuning fork as a time-determining link for an electric clock Die Invention relates to a tuning fork as a time-determining member for an electric Clock. In this context it can be assumed that such Tuning forks in electrical clocks represent an oscillating link that drives them, which is self-excited and in its natural frequency by electromagnetic drive systems is entertained in vibration. Such tuning forks are in the Space between their prongs connected by a web extending holding arm on Watch case set; at least one of its prongs is linked to the oscillation into a rotary movement converting transmission device for driving the pointer mechanism mechanically in operative connection.
Der Erfindung liegt die Aufgabe zugrunde, eine Stimmgabel für elektrische Uhren zur Verfügung zu stellen, die unter Berücksichtigung von deren Laufgenauigkeit eine weitere Verkleinerung des Uhrengehäuses ermöglicht. Diese Aufgabe wird dadurch gelöst, daß man den Zinken der Stimmgabel etwa von dem Bereich ab, in dem das freie Ende des Haltearmes liegt, je eine den Raum zwischen den Zinken verkleinernde Einbuchtung gibt. Im Bereich der Einbuchtung der einen Zinke ist damit Raum geschaffen, um die elektrische Batterie solcher elektrischer Uhren näher an die Stimmgabel heranzurücken.The invention is based on the object of a tuning fork for electrical To make clocks available that take into account their running accuracy allows a further downsizing of the watch case. This is what makes this job solved that the prongs of the tuning fork approximately from the area in which the free At the end of the holding arm lies an indentation that reduces the space between the prongs gives. In the area of the indentation of one prong, space is thus created around the move the electric battery of such electric watches closer to the tuning fork.
In der Zeichnung sind die Zinken der erfindungsgemäßen Stimmgabel mit den Bezugsziffern 1 und 2 bezeichnet, sie sind über einen Steg 3 miteinander verbunden und werden über einen sich in den Raum zwischen ihnen erstreckenden Haltearm 4 am Uhrengehäuse festgelegt. Am freien Ende jeder Zinke 1, 2 sind elektromechanische Wandler T1 und T2 befestigt, die bis auf die unterschiedliche Ausbildung ihrer Spulen gleichartig gestaltet sind. Der Wandler T besteht aus einem zylindrischen Topf 5 aus magnetisierbarem Material, wie Eisen, und einem Permanentmagnetstab 6, der in dem Topf koaxial festgelegt ist. Mit 7 ist eine Antriebsspule bezeichnet, die auf einen Träger 8 aufgewickelt ist. Zwischen dem zylindrischen Topf 5 und der Antriebsspule 7 ist ein ringförmiger Luftspalt 9 gebildet. Der Wandler T2 besteht aus einem magnetischen Element 10, das mit einer um einen rohrförmigen Träger gewickelten Antriebsspule zusammenwirkt. An einem Zapfen 11 der Zinke 2 ist eine Klinke 12 festgelegt, die in ein mit dem Gangwerk gekoppeltes Klinkenrad eingreift.In the drawing, the prongs of the tuning fork according to the invention are denoted by the reference numerals 1 and 2 , they are connected to one another via a web 3 and are fixed to the watch case via a retaining arm 4 extending into the space between them. Electromechanical transducers T1 and T2 are attached to the free end of each prong 1, 2 and are designed in the same way except for the different design of their coils. The transducer T consists of a cylindrical pot 5 made of magnetizable material, such as iron, and a permanent magnet rod 6 which is fixed coaxially in the pot. 7 with a drive coil is referred to, which is wound on a carrier 8. An annular air gap 9 is formed between the cylindrical pot 5 and the drive coil 7. The transducer T2 consists of a magnetic element 10 which interacts with a drive coil wound around a tubular support. A pawl 12 is fixed on a pin 11 of the prong 2 and engages in a ratchet wheel coupled to the gear mechanism.
Wie nun der Zeichnung entnehmbar ist, sind die beiden Zinken 1, 2 der Stimmgabel etwa von dem Bereich ab, in dem das freie Ende des Haltearmes 4 liegt, mit je einer den Raum zwischen ihnen verkleinernden Einbuchtung 13,14 versehen, wodurch in der einen Einbuchtung 13 zusätzlich Raum Azur Unterbringung der Batterie 15 geschaffen ist. Die Einbuchtungen der Stimmgabelzinken bringen somit die Möglichkeit einer Verkleinerung des Uhrengehäuses.As can now be seen from the drawing, the two prongs 1, 2 of the tuning fork are provided approximately from the area in which the free end of the retaining arm 4 is located, each with an indentation 13 , 14 reducing the space between them, whereby in one Indentation 13 in addition space azure housing the battery 15 is created. The indentations of the tuning fork prongs thus make it possible to reduce the size of the watch case.
