Description

Die Erfindung betrifft eine Uhr mit analoger Zeitanzeige mit einem mittels einer Welle in einer Rotationsebene rotierendem Zeiger und mit einem parallel zu der Rotationsebene liegendem Zifferblatt. Dabei weist das Zifferblatt eine äußere Skala auf, die konzentrisch mit dem Zifferblatt und mit einem Abstand zum Rand des Zifferblattes angeordnet ist, der geringer ist als der radiale Abstand zu ihrem Zentrum, die mit dem Zeiger, insbesondere mit der Zeigerspitze, die Zeit einer Zeiteinheit anzeigend korrespondiert und die eine die exakte Zeitanzeige verhindernde Unterbrechung aufweist.The invention relates to a timepiece with an analog time display with a pointer rotating by means of a shaft in a plane of rotation and with a dial lying parallel to the plane of rotation. In this case, the dial has an outer scale, which is arranged concentrically with the dial and at a distance from the edge of the dial, which is less than the radial distance to its center, with the pointer, in particular with the pointer tip, the time of a unit time indicating and having an exact time display preventing interruption.

Es sind allgemein Uhren bekannt, bei denen zur analogen Zeitanzeige mehrere Zeiger gleichsinnig aber versetzt gemeinsam um eine Drehachse drehen, wobei deren Wellen als konzentrisch zu der Drehachse liegende Wellen und Hohlwellen ausgebildet sind.There are generally watches known in which the analog time display several pointers in the same direction but offset together rotate about a rotation axis, the waves being formed as concentric with the axis of rotation shafts and hollow shafts.

Diese Zeiger haben unterschiedliche Längen und überstreichen verschiedene Skalen eines Zifferblattes. Dabei sind die Skalen, zumindest aber eine Skala im Bereich des äußeren Randes des Zifferblattes angeordnet. Das bietet die Möglichkeit, unterschiedliche physikalische Größen, insbesondere unterschiedliche Zeiteinheiten, wie Stunden, Minuten und Sekunden über je einen vollen Zeigerumlauf darzustellen. Aber auch gleiche Zeiteinheiten lassen sich somit darstellen, etwas bei einem Chronographen die ablaufenden Sekunden der Zeitanzeige und die gestoppten Sekunden mittels eines zum Sekundenzeiger versetzt laufenden Chronographenzeigers.These hands have different lengths and cover different scales of a dial. The scales, or at least a scale in the region of the outer edge of the dial are arranged. This offers the possibility to represent different physical quantities, in particular different time units, such as hours, minutes and seconds, each over a full pointer revolution. But even the same time units can be Thus, somewhat in a chronograph, the running seconds of the time display and the seconds stopped represent by means of a chronograph hand shifted to the second hand.

Es sind aber auch sektorfömige Zifferblätter bekannt, bei denen ein voller Umlauf einer Zeigerwelle in einem Sektor dargestellt wird. In dem Sektor sind dabei Skalen unterschiedlichen Durchmessers vorgesehen, die von einer entsprechenden Anzahl von Zeigern, die sich auf derselben Welle befinden aber winkelversetzt sind und einen der jeweiligen Skala entsprechende jeweils unterschiedliche Länge aufweisen. Dies ist bereits aus alten astronomischen Uhren bekannt. Ein gegenwärtiger Vertreter einer solchen sektorförmigen Anzeige ist der DE 20 2011 001 377 U1 zu entnehmen.But there are also sektorfömige dials known in which a full circulation of a pointer shaft is shown in a sector. In the sector, scales of different diameters are provided, which are angularly offset by a corresponding number of pointers which are located on the same shaft and each have a different length corresponding to the respective scale. This is already known from ancient astronomical clocks. A current representative of such a sector-shaped display is the DE 20 2011 001 377 U1 refer to.

Auch die FR 437 680 A zeigt eine sektorförmige Anzeige, allerdings nur mit einer Skala im Sektor.Also the FR 437 680 A shows a sector-shaped display, but only with a scale in the sector.

Die DE 10 2005 015 178 A1 offenbart eine Anzeige mit einem Zeiger, der um eine Drehachse drehbar ist und durch die Drehung im Zusammenwirken mit einer Skala einen ersten physikalischen Wert darstellt. Dabei ist vorgesehen, dass der Zeiger oder der Zeigerhintergrund einen zweiten physikalischen Wert proportional anzeigt.The DE 10 2005 015 178 A1 discloses a display having a pointer that is rotatable about an axis of rotation and that represents a first physical value through rotation in cooperation with a scale. It is provided that the pointer or the pointer background displays a second physical value proportionally.

Hierbei handelt es sich um eine Anzeige, wie sie auch in den allgemein bekannten Mehrfachmessinstrumenten üblich ist. Dabei wird ein und derselbe Zeiger genutzt, um je nach eingestellter Messart oder je nach eingestelltem Messbereich entsprechend unterschiedliche Werte anzuzeigen.This is a display, as is common in the well-known multimeter. One and the same pointer is used to display different values depending on the set measuring mode or the set measuring range.

Die EP 1 939 700 A2 offenbart eine Uhr mit analoger Zeitanzeige, bei der mittels eines Schrittmotors ein Minutenzeiger in einer Rotationsebene rotiert. Die Uhr weist ein Anzeigefeld auf, auf dem ein Zifferblatt angeordnet ist, das parallel zu der Rotationsebene liegt und das eine äußere Skala aufweist. Dies Skala ist konzentrisch mit dem Zifferblatt und mit einem Abstand zum Rand des Zifferblattes angeordnet ist, der geringer ist als der radiale Abstand zu ihrem Zentrum. Die Skala korrespondiert mit dem Zeiger, die Zeit einer Zeiteinheit anzeigend. Bei dem Anzeigefeld handelt es sich um ein elektronisches Display und die Darstellung der Skala lässt sich damit elektronisch steuern und das Zifferblatt wird elektronisch auf dem Anzeigefeld erzeugt. Die Skala ist sektorförmig ausgebildet. Eine Bewegungseinheit steuert die Bewegung sowohl des Stunden- und des Minutenzeigers als auch des Displays. Der Skalensektor wird immer dort zur Anzeige gebracht, wo sich der entsprechende Zeiger gerade befindet. Das eröffnet die Möglichkeit, die Flächen des Displays, die gerade nicht für die Darstellung der Zeitskala benötigt werden, für die Darstellung anderer Informationen zu nutzen. Eine die exakte Zeitanzeige verhindernde Unterbrechung ist hier nicht vorgesehen.The EP 1 939 700 A2 discloses a timepiece with an analogue time display in which a minute hand rotates in a plane of rotation by means of a stepping motor. The watch has a display panel on which a dial is placed, which is parallel to the plane of rotation and which has an outer scale. This scale is concentric with the dial and arranged at a distance to the edge of the dial which is less than the radial distance to its center. The scale corresponds to the pointer, indicating the time of a unit of time. The display panel is an electronic display and the display of the scale can be controlled electronically and the dial is generated electronically on the display panel. The scale is sector-shaped. A movement unit controls the movement of both the hour and minute hands and the display. The scale sector is always displayed where the corresponding pointer is currently located. This makes it possible to use the areas of the display, which are currently not needed for the representation of the time scale, for the presentation of other information. An exact time display preventing interruption is not provided here.

Die WO 2006/010989 A1 betrifft eine Uhr mit analoger Anzeige. Darin sind zwei Zifferblätter vorgesehen, die ineinander eingebettet sind. Ein Minuten- und ein Stundenzeiger rotieren in je einer Rotationsebene. Beide Zifferblätter liegen parallel zu den Rotationsebenen. Sie weisen je eine Skala auf, die jeweils konzentrisch mit dem Zifferblatt sind. Jede Skala korrespondiert mit dem Zeiger, die Zeit einer Zeiteinheit anzeigend. Beide Zeiger ragen über das Zentrum hinaus, um es zu ermöglichen, dass zwei Personen, die einander gegenüber sitzen, die Zeit gleichzeitig ablesen können. Eine die exakte Zeitanzeige verhindernde Unterbrechung ist hier nicht vorgesehen.The WO 2006/010989 A1 concerns a clock with analog display. In it two dials are provided, which are embedded in each other. One minute hand and one hour hand rotate in a single rotation plane. Both dials are parallel to the rotation planes. They each have a scale, each concentric with the dial. Each scale corresponds to the pointer, indicating the time of a unit of time. Both hands extend beyond the center to allow two persons sitting opposite each other to read the time simultaneously. An exact time display preventing interruption is not provided here.

Aus der EP 0 408 512 B1 oder deren Übersetzung, der DE 69 000 458 T2 ist eine Chronographen-Armbanduhr bekannt, die ein Zifferblatt, das eine Hauptskalenteilung zur Stundenanzeige mit Hilfe eines Stundenzeigers aufweist. Weiterhin ist ein Minutenzeiger, ein zentraler Chronographenzeiger, der mittels eines ersten Druckknopfs in Betrieb gesetzt und angehalten sowie mittels eines zweiten Druckknopfes auf null zurückgestellt werden kann, vorgesehen. Schließlich weist diese Chronographen-Armbanduhr einen kleinen Sekundenzeiger, einen Minuten-Abwärtszähler und einen Stundenzähler auf.From the EP 0 408 512 B1 or their translation, the DE 69 000 458 T2 is a chronograph wristwatch known to have a dial, which is a main graduation to the Hour display using an hour hand. Furthermore, a minute hand, a central chronograph hand, which can be set by means of a first push-button in operation and stopped and reset by means of a second push button to zero, is provided. Finally, this chronograph wristwatch has a small second hand, a minute down counter and an hour counter.

Bei dieser Chronographen-Armbanduhr fällt auf, dass die Skala im Bereich des äußeren Randes des Zifferblattes, d.h. die Skala, die am nähesten zum äußeren Rand des Zifferblattes liegt und die der Anzeige der Sekunden durch den Chronographenzeiger, der Minuten- und der Stundenanzeige dient, durch die Skala des Sekundenabwärtszählers, durch die Skala des Sekundenzeigers, durch die Skala des Stundenzählers und durch das Fenster der Datumsanzeige unterbrochen ist.In this chronograph wristwatch it is noticeable that the scale in the region of the outer edge of the dial, i. the scale closest to the outer edge of the dial, indicating the seconds by the chronograph hand, the minute and hour digits, the second hand counter scale, the second hand dial scale, the hour counter scale and the hour hand dial Window of the date display is interrupted.

Bei derartigen Unterbrechungen der äußeren Skala zeigt sich das Problem, dass die exakte Ablesbarkeit nicht mehr gewährleistet ist.With such interruptions of the outer scale, there is the problem that the exact readability is no longer guaranteed.

Es ist daher die Aufgabe der Erfindung, bei einem Zifferblatt, dessen äußere Skala, d.h. die Skala, die konzentrisch mit und als näheste zum Rand des Zifferblattes liegt, eine Unterbrechung aufweist, bei jeder Stellung eines mit dieser Skala korrespondierenden Zeigers eine exakte Ablesbarkeit zu erreichen.It is therefore the object of the invention, in a dial whose outer scale, i. the scale, which is concentric with and closest to the edge of the dial, has an interruption to achieve an exact readability at each position of a pointer corresponding to this scale.

Diese Aufgabe wird durch eine Uhr mit den Merkmalen des Anspruches 1 gelöst. Die Ansprüche 2 bis 8 zeigen Ausführungsformen dieser Uhr.This object is achieved by a clock with the features of claim 1. Claims 2 to 8 show embodiments of this clock.

Erfindungsgemäß ist eine Uhr der eingangs genannten Art derart ausgebildet, dass das Zifferblatt eine Hilfsskala aufweist, die mit demselben Zeiger die Zeit derselben Zeiteinheit wie im Bereich der Unterbrechung anzeigend korrespondiert. Damit wird es möglich, mittels der Hilfsskala ein Ablesen der Zeit in der Zeiteinheit, was durch bei der unterbrochenen Skala nicht exakt möglich ist, genau vorzunehmen. Da die Hilfsskala einfach grafisch, durch Prägung oder durch Applikation auf das Zifferblatt aufgebracht werden kann und den Zeiger, der ohnehin vorhanden ist, mittels der Hilfsskala selbst die Anzeige ermöglicht, wird die Herstellung der Exaktheit der Anzeige ohne weitere mechanische Mittel ermöglicht.According to the invention a clock of the type mentioned is designed such that the dial has an auxiliary scale, the same time with the same pointer Time unit as indicated in the area of the interruption corresponds. This makes it possible, by means of the auxiliary scale, a reading of the time in the time unit, which is not exactly possible by the broken scale, exactly. Since the auxiliary scale can be easily graphically applied by embossing or by application to the dial and the pointer, which is present anyway, by means of the auxiliary scale itself allows the display, the production of the accuracy of the display is made possible without further mechanical means.

Die Unterbrechungen der Skala können unterschiedliche Ursachen haben. So bilden in den Bereich der Skala hineinragende andere Skalen anderer Anzeigen, beispielsweise Datumsanzeigen genauso Unterbrechungen, wie im Bereich der Skala angebrachte Marken oder Herkunftsbezeichnungen oder aber auch Fenster, die das darunterliegende Uhrwerk sichtbar machen. Derartige Fenster eignen sich besonders bei mechanischen Uhren.The interruptions of the scale can have different causes. For example, other scales of other displays that project beyond the scale, such as date indications, form interruptions, as well as markings or denominations of origin attached to the scale, or even windows that make the underlying movement visible. Such windows are particularly suitable for mechanical watches.

Sehr oft ist die Skala auch als kombinierte Skala zur Anzeige mehrerer Zeiteinheiten, wie Sekunden, Minuten oder Stunden ausgebildet. Die Erfindung bezieht auch solche kombinierten Skalen mit ein. Das bedeutet, dass die Hilfsskala auch den durch die Unterbrechung verlorenen gegangen Teil einer derart kombinierten Skala wiedergeben kann. Dementsprechend korrespondieren dann auch die anderen Zeiger mit der Hilfsskala, wenn ihre Anzeige, insbesondere ihre jeweilige Zeigerspitze in den Bereich der Unterbrechung eintritt.Very often, the scale is also designed as a combined scale for displaying a plurality of time units, such as seconds, minutes or hours. The invention also includes such combined scales. This means that the auxiliary scale can also reproduce the part lost by the interruption of such a combined scale. Accordingly, the other hands also correspond to the auxiliary scale when their display, in particular their respective pointer tip, enters the region of the interruption.

In einer Ausführungsform ist vorgesehen, dass die Hilfsskala als konzentrisch zur Skala ausgebildeter Skalensektor mit einem Sektorwinkel, der mindestens gleich dem Sektorwinkel der Unterbrechung ist, ausgebildet ist.In one embodiment, it is provided that the auxiliary scale is designed as a scale sector formed concentrically with the scale, with a sector angle that is at least equal to the sector angle of the interruption.

Die Unterbrechung bildet einen Sektor auf der Skala, d.h. einen Abschnitt. Werden nun die jeweiligen Enden dieses Abschnittes mit virtuellen Linien mit dem Zentrum der Skala verbunden, so schließen diese virtuellen Linien einen Winkel ein, der als Sektorwinkel bezeichnet wird. Der Skalensektor der Hilfsskala weist nun gemäß dieser Ausführungsform denselben Sektorwinkel auf, wie der unterbrochene Abschnitt der Skala.The interruption forms a sector on the scale, ie a section. Now, when the respective ends of this section are connected to the center of the scale with virtual lines, these virtual lines include an angle called a sector angle. The scale sector of the auxiliary scale according to this embodiment now has the same sector angle as the interrupted section of the scale.

Die Skala selbst kann unterschiedliche Formen aufweisen. So sind eckige Skalen genauso vorstellbar, wie ovale oder runde, je nach der Formgebung der Uhr. Bei einer runden Gestaltung der Uhr wird die Skala vorzugsweise kreisförmig ausgebildet sein. In diesem Falle ist in einer günstigen Ausgestaltung vorgesehen, dass der Skalensektor als Kreissektor ausgebildet ist. Bei anderen Formen der Skala können dann der Skalensektor eine andere, der Form der Skala entsprechende Form haben; im Falle einer rechteckigen Gestaltung beispielsweise auch eine gerade Ausbildung aufweisen.The scale itself can have different shapes. So angular scales are just as conceivable as oval or round, depending on the shape of the clock. In a round design of the clock, the scale will preferably be circular. In this case, it is provided in a favorable embodiment that the scale sector is designed as a circular sector. In other forms of the scale, the scale sector may then have a different form, corresponding to the shape of the scale; in the case of a rectangular design, for example, also have a straight training.

Für den Fall, dass es die Größe der die Unterbrechung verursachenden Gestaltung zulässt, d.h. noch ausreichend Raum zwischen der Unterbrechung und dem Zentrum der Skala ist, kann die Hilfsskala in dem Bereich zwischen Unterbrechung und Zentrum angeordnet sein.In the event that it allows the size of the disruption causing design, i. if there is still enough space between the break and the center of the scale, the auxiliary scale may be located in the area between the break and the center.

Um hierbei die Exaktheit der Anzeige zu erhöhen, ist es zweckmäßig, dass der Zeiger in seinem die Hilfsskala überstreichenden Bereich mit einer Verjüngung versehen ist. Diese Verjüngung hat die gleiche Funktion wie eine verjüngte Zeigerspitze, nämlich die Zuordnung zwischen Zeiger und Hilfsskala eindeutig zu finden und damit die Ablesegenauigkeit zu erhöhen.In order to increase the accuracy of the display, it is expedient that the pointer is provided in its auxiliary scale over the sweeping area with a taper. This taper has the same function as a tapered pointer tip, namely to find the assignment between pointer and auxiliary scale clearly and thus increase the reading accuracy.

Die Hilfsskala kann aber auch auf der anderen Seite des Zentrums der Skala angeordnet werden. Hierzu sieht eine Ausführung der Erfindung vor, dass die Hilfsskala auf der der Unterbrechung abgewandten Hälfte des Zifferblattes angeordnet ist und der Zeiger eine sich zur Zeigerspitze entgegengesetzt erstreckende Zeigerverlängerung aufweist, die mit der Hilfsskala die Zeit anzeigend korrespondiert. Diese Zeigerverlängerung ist fest, vorzugsweise einstückig mit dem Zeiger verbunden und somit Bestandteil des Zeigers, weshalb die Anzeige der Zeit nach wie vor mit demselben Zeiger erfolgt, was bedeutet, dass keine weiteren mechanischen Bauteile erforderlich sind. Überstreicht nun die Zeigerspitze die durch die Unterbrechung nicht mehr vorhandene Skala, so kann mittels Zeigerverlängerung die Zeit nach wie vor exakt abgelesen werden, nunmehr an der Hilfsskala.The auxiliary scale can also be arranged on the other side of the center of the scale. For this purpose, an embodiment of the invention provides that the auxiliary scale on the the interruption facing away from the half of the dial is arranged and the pointer has a pointer tip to the oppositely extending pointer extension corresponding to the auxiliary scale indicating the time. This pointer extension is fixed, preferably integrally connected to the pointer and thus part of the pointer, which is why the display of time is still done with the same pointer, which means that no further mechanical components are required. If the pointer tip now passes over the scale no longer present due to the interruption, the time can still be read exactly by means of the pointer extension, now on the auxiliary scale.

In einer weiteren Ausgestaltung ist dazu vorgesehen, dass die Zeigerverlängerung mit einer sich verjüngenden Spitze versehen ist. Durch diese Verjüngung wird wiederrum die Genauigkeit des Ablesens erhöht.In a further embodiment, it is provided that the pointer extension is provided with a tapered tip. This rejuvenation, in turn, increases the accuracy of the reading.

Bei der Anordnung der Hilfsskala auf der zur Unterbrechung abgewandten Seite der Skala ist in einer weiteren Ausgestaltung vorgesehen, dass die Hilfsskala als eine mit dem Zentrum der Skala geometrisch ausgeführte zentrische Streckung (genauer zentrische Streckung mit negativem Streckungsfaktor) einer Fortsetzung der Skala im Bereich der Unterbrechung ausgebildet ist. Dies bedeutet mit anderen Worten, dass die Hilfsskala als der Teil der Skala, die vorhanden wäre, wenn die Unterbrechung die Skala nicht unterbrechen würde, an dem Zentrum der Skala gespiegelt, seitenverkehrt und verkleinert wird. Es dabei selbstverständlich, dass trotz dieser geometrischen Abbildung etwaige Ziffern an der Hilfsskala in lesbar richtiger Form dargestellt werden. Die Zeigerverlängerung liegt dabei auf einer geraden Fortsetzung einer Längserstreckung des Zeigers zwischen Zeigerspitze und Zeigerwelle. Dies stellt eine technogisch einfache Realisierung dar, da der Zeiger mit den gleichen technologischen Schritten gefertigt werden kann. Auch für den Benutzer stellt dies eine einfach nachzuvollziehende Anzeige dar.In the arrangement of the auxiliary scale on the side facing away from the interruption side of the scale is provided in a further embodiment that the auxiliary scale as a geometrically running with the center of the scale centric extension (more centric extension with negative extension factor) a continuation of the scale in the interruption is trained. This means, in other words, that the auxiliary scale, as the part of the scale that would be present if the interruption did not interrupt the scale, is mirrored at the center of the scale, reversed and downsized. It goes without saying that, in spite of this geometric illustration, any digits on the auxiliary scale are displayed in a readably correct form. The pointer extension lies on a straight continuation of a longitudinal extension of the pointer between pointer tip and pointer shaft. This represents a technogically simple Realization is because the pointer can be made with the same technological steps. Also for the user, this is an easy-to-follow display.

The invention will be explained in more detail with reference to an embodiment. In the accompanying drawings shows

Fig. 1 zeigt eine Uhr 1 mit analoger Zeitanzeige. Die Uhr 1 weist ein Gehäuse 2 auf. In dem Gehäuse 2 ist ein Zifferblatt 3 angeordnet. Das Zifferblatt 3 weist eine äußere Skala 4 auf, die konzentrisch zu dem Zentrum des Zifferblattes und mit einem Abstand 5 zum Rand 6 des Zifferblattes 3 angeordnet ist, der geringer ist als der radiale Abstand 7 zu ihrem Zentrum 8. Fig. 1 shows a clock 1 with analog time display. The clock 1 has a housing 2. In the housing 2, a dial 3 is arranged. The dial 3 has an outer scale 4, which is arranged concentrically to the center of the dial and with a distance 5 to the edge 6 of the dial 3, which is less than the radial distance 7 to its center. 8

Weiterhin weist die Uhr 1 einen Zeiger 9 auf, der mittels einer Welle 10 in einer nicht näher dargestellten Rotationsebene rotiert. Das Zifferblatt 3 liegt dabei parallel zu der Rotationsebene und die Welle 10 im Zentrum 8 des Zifferblattes 3.Furthermore, the clock 1 has a pointer 9, which rotates by means of a shaft 10 in a rotation plane, not shown. The dial 3 is parallel to the plane of rotation and the shaft 10 in the center 8 of the dial. 3

Die Skala 4 korrespondiert mit dem Zeiger 9, insbesondere mit der Zeigerspitze 11, die Zeit einer Zeiteinheit anzeigend, d.h. der Zeiger 9 wird von einem nicht näher dargestellten Skala/Zeit-synchronen Antrieb gedreht. Die Zeigerspitze 11 nimmt dabei zeitlich wechselnde Positionen auf der Skala 4 ein. Diese Stellungen auf der Skala 4 repräsentieren stets eine Zeitangabe in einer Zeiteinheit.The scale 4 corresponds to the pointer 9, in particular to the pointer tip 11, indicating the time of a unit of time, ie the pointer 9 is not closer by one turned scale / time-synchronous drive rotated. The pointer tip 11 takes on temporally changing positions on the scale 4. These positions on the scale 4 always represent a time in a unit of time.

Um die Arbeitsweise des Antriebs, d.h. des Uhrwerks sehen zu können, ist in dem Zifferblatt 3 ein Fenster 12 eingebracht. In diesem Ausführungsbeispiel handelt es sich bei dem Fenster um einen Ausschnitt für ein nicht näher dargestelltes Tourbillon.To improve the operation of the drive, i. to see the clockwork, a window 12 is inserted in the dial 3. In this embodiment, the window is a section for a tourbillon not shown in detail.

Die Uhr 1 weist neben der Minutenanzeige auf der äußeren Skala 4 auch noch andere Anzeigen auf, nämlich eine Sekundenanzeige 13 und die eine Stundenanzeige 14.The clock 1 has, in addition to the minute display on the outer scale 4, also other displays, namely a seconds display 13 and the one hour display 14.

Das Tourbillon ist nur mit einem Fenster 12 sichtbar, welches in den Bereich der äußeren Skala 4 eindringt. Damit entsteht in der Skala 4 eine Unterbrechung 13, die die exakte Zeitanzeige verhindert.The tourbillon is visible only with a window 12 which penetrates into the area of the outer scale 4. This results in the scale 4 an interruption 13, which prevents the exact time display.

Um dies zu überwinden, weist das Zifferblatt 3 eine Hilfsskala 15 auf. Diese Hilfsskala 15 korrespondiert mit demselben Zeiger 9 derart, dass sie die Zeit derselben Zeiteinheit im Bereich der Unterbrechung 13 anzeigt.To overcome this, the dial 3 has an auxiliary scale 15. This auxiliary scale 15 corresponds to the same pointer 9 in such a way that it indicates the time of the same time unit in the area of the interruption 13.

Die Hilfsskala 16 ist als konzentrisch zur Skala 4 ausgebildeter Skalensektor mit einem Sektorwinkel α, der mindestens gleich dem Sektorwinkel β der Unterbrechung 13 ist, ausgebildet. Die Sektorwinkel α und β werden in den nachfolgenden Beispielen erläutert.The auxiliary scale 16 is designed as a concentric with the scale 4 trained scale sector with a sector angle α, which is at least equal to the sector angle β of the interruption 13. The sector angles α and β will be explained in the following examples.

Gemäß Fig. 1 sind der Teil des Gehäuses 2, der das Zifferblatt 3 aufnimmt, das Zifferblatt 3 selbst und folglich auch die Skala 4 kreisrund gestaltet. Dementsprechend ist auch die Hilfsskala 16 als kreissektorförmiger Skalensektor ausgebildet.According to Fig. 1 are the part of the housing 2, which receives the dial 3, the dial 3 itself and consequently the scale 4 circular designed. Accordingly, the auxiliary scale 16 is formed as a sector-shaped scale sector.

Die Hilfsskala 16 ist dabei auf der dem Fenster 12 oder der Unterbrechung 13 vom Zentrum 8 abgewandten Hälfte des Zifferblattes 3 angeordnet. Dabei ist die Hilfsskala 16 als eine mit dem Zentrum 8 der Skala 4 geometrisch ausgeführte zentrische Streckung mit negativem Streckungsfaktor einer Fortsetzung der Skala 4 im Bereich der Unterbrechung 13 ausgebildet. Dies bedeutet mit anderen Worten, dass die Hilfsskala 16 den Teil der Skala 4, der die Skala fortsetzen würde, wäre die Unterbrechung 13 nicht vorhanden, als eine Darstellung dieses fiktiven Teils der Skala 4, die an dem Zentrum 8 der Skala 4 gespiegelt, seitenverkehrt und verkleinert wird, wiedergibt. Damit ist der Radius der Hilfsskala 16 kleiner als der Radius der Skala selbst und die letzte sichtbare Ziffer "25", die auf der Skala 4 rechts von der Unterbrechung 13 zu sehen ist, erscheint an dem linken Ende der Hilfsskala 16. Umgekehrt erscheint die letzte sichtbare Ziffer "35", die auf der Skala 4 links von der Unterbrechung 13 zu sehen ist, an dem rechten Ende der Hilfsskala 16. Wie daraus auch deutlich wird, wiederholen sich die Zahlen "25" und "35", was dem Merkmal der Erfindung entspricht, dass - wie nachfolgend noch erläutert wird - der Sektorwinkel α des Skalen- oder Kreissektors der Hilfsskala 16 zumindest gleich dem Sektorwinkel β der Unterbrechung 13 ist. In diesem Falle ist der der Sektorwinkel α nicht nur gleich sondern größer als der Sektorwinkel β.The auxiliary scale 16 is on the window 12 or the Interruption 13 facing away from the center 8 half of the dial 3 arranged. In this case, the auxiliary scale 16 is formed as a centered with the center 8 of the scale 4 running central extension with negative extension factor of a continuation of the scale 4 in the region of the interruption 13. In other words, the auxiliary scale 16 reverses the portion of the scale 4 that would continue the scale if the interruption 13 were absent, as a representation of that fictitious portion of the scale 4 mirrored at the center 8 of the scale 4 and is reduced, reflects. Thus, the radius of the auxiliary scale 16 is smaller than the radius of the scale itself and the last visible number "25", which can be seen on the scale 4 to the right of the interruption 13, appears at the left end of the auxiliary scale 16. Conversely, the last appears visible number "35", which can be seen on the scale 4 to the left of the interruption 13, at the right end of the auxiliary scale 16. As can be seen from this, the numbers "25" and "35" are repeated, which corresponds to the feature of Invention corresponds to that - as will be explained below - the sector angle α of the scale or circular sector of the auxiliary scale 16 is at least equal to the sector angle β of the interruption 13. In this case, the sector angle α is not only equal to but greater than the sector angle β.

Zur Anzeige der Zeit, in diesem Falle zur Anzeige der Minuten während der Zeit, in der sich der Zeiger 9 mit seiner Zeigerspitze 11 im Bereich der Unterbrechung 13 befindet, weist der Zeiger 9 eine sich zur Zeigerspitze 11 entgegengesetzt erstreckende Zeigerverlängerung 17, auf, die mit der Hilfsskala 16 entsprechend korrespondiert.To indicate the time, in this case to display the minutes during the time in which the pointer 9 is located with its pointer tip 11 in the region of the interruption 13, the pointer 9 has a pointer tip 11 opposite extending pointer extension 17, the with the auxiliary scale 16 corresponds accordingly.

Die Zeigerverlängerung 17 liegt dabei auf einer geraden Fortsetzung einer Längserstreckung des Zeigers 9 zwischen Zeigerspitze 11 und Zeigerwelle 10. Dies stellt eine technogisch einfache Realisierung dar, da der Zeiger mit den gleichen technologischen Schritten gefertigt werden kann. Auch für den Benutzer stellt dies eine einfach nachzuvollziehende Anzeige dar.The pointer extension 17 lies on a straight continuation of a longitudinal extension of the pointer 9 between pointer tip 11 and pointer shaft 10. This provides a technically simple realization, since the pointer can be manufactured with the same technological steps. Also for the user, this is an easy-to-follow display.

So kann mittels der Zeigerverlängerung 17 die Zeit nach wie vor exakt abgelesen werden, nunmehr an der Hilfsskala 16, wobei zur Erhöhung der Genauigkeit des Ablesens die Spitze 18 der Zeigerverlängerung 17 eine Verjüngung aufweist, in gleicher Weise wie die Zeigerspitze 11.Thus, the time can still be read exactly by means of the pointer extension 17, now on the auxiliary scale 16, wherein the tip 18 of the pointer extension 17 has a taper to increase the accuracy of the reading, in the same manner as the pointer tip eleventh

Bei dem in Fig. 2 und Fig. 3 dargestellten Ausführungsbeispielen ist die Hilfsskala 16 ebenfalls als konzentrisch zur Skala 4 ausgebildeter Skalensektor mit einem Sektorwinkel α, der mindestens gleich dem Sektorwinkel β der Unterbrechung ist, ausgebildet.At the in Fig. 2 and Fig. 3 illustrated embodiments, the auxiliary scale 16 is also formed as concentric with the scale 4 trained scale sector with a sector angle α, which is at least equal to the sector angle β of the interruption.

Die Unterbrechung 13 bildet einen Sektor, bei der kreisförmigen Ausbildung einen Kreissektor auf der Skala 4. Werden nun die jeweiligen Enden 19 und 20 dieses Sektors oder der Unterbrechung mit virtuellen Linien 21 und 22 mit dem Zentrum 8 der Skala 4 verbunden, so schließen diese virtuellen Linien 21 und 22 einen Winkel β ein, der als Sektorwinkel β bezeichnet wird. Der Skalen- oder Kreissektor der Hilfsskala 16 weist nun nach dieser Definition ebenfalls einen Sektorwinkel α auf, der in den Beispielen nach Fig. 2 und 3 gleich dem Sektorwinkel β der Unterbrechung 13 auf der Skala 4 ist.The interruption 13 forms a sector, in the circular formation of a circle sector on the scale 4. If now the respective ends 19 and 20 of this sector or the interruption with virtual lines 21 and 22 connected to the center 8 of the scale 4, so close these virtual Lines 21 and 22 an angle β, which is referred to as sector angle β. The scale or circular sector of the auxiliary scale 16 now also has a sector angle α according to this definition, which in the examples according to FIG FIGS. 2 and 3 is equal to the sector angle β of the interruption 13 on the scale 4.

Bei dem in Fig. 2 dargestellten Beispiel ist die Hilfsskala 16 ebenfalls auf der dem Fenster 12 oder der Unterbrechung 13 vom Zentrum 8 abgewandten Hälfte des Zifferblattes 3 angeordnet, allerdings nicht in gerader Linie gegenüber der Unterbrechung 13, wie in Fig. 1, sondern mit einem Winkel seitlich versetzt. Die Hilfsskala 16 gibt dabei den Teil der Skala 4, der die Skala fortsetzen würde, wäre die Unterbrechung 13 nicht vorhanden, als eine Darstellung dieses fiktiven Teils der Skala 4 gespiegelt und verkleinert, d.h. insbesondere mit kleinerem Radius als der Radius der Skala 4 wieder. Eine Seitenverkehrung ist hier möglich, aber nicht erforderlich, da die Skala 4 keine Bezifferung aufweist.At the in Fig. 2 the auxiliary scale 16 is also arranged on the window 12 or the interruption 13 facing away from the center 8 half of the dial 3, but not in a straight line with respect to the interruption 13, as in Fig. 1 but laterally offset with an angle. The auxiliary scale 16 gives the part of the scale 4, which would continue the scale, the interruption 13 would not exist as a Representation of this notional part of the scale 4 mirrored and reduced, ie in particular with a smaller radius than the radius of the scale 4 again. A side change is possible here, but not required, since the scale 4 has no figuring.

Zur Anzeige der Zeit während der Zeit, in der sich der Zeiger 9 mit seiner Zeigerspitze 11 im Bereich der Unterbrechung 13 befindet, weist der Zeiger 9 eine Zeigerverlängerung 23 auf, die mit der Hilfsskala 16 entsprechend korrespondiert.To indicate the time during the time in which the pointer 9 is located with its pointer tip 11 in the region of the interruption 13, the pointer 9 has a pointer extension 23 which corresponds to the auxiliary scale 16 accordingly.

Die Zeigerverlängerung 23 liegt dabei in einem Winkel γ zur geraden Fortsetzung einer Längserstreckung des Zeigers 9 zwischen Zeigerspitze 11 und Zeigerwelle 10. Dies stellt insofern eine günstige Lösung dar, als dass damit je nach Möglichkeiten der Unterbringung oder gestalterischen Erfordernissen die Hilfsskala 16 weitgehend wahlfrei untergebracht werden kann.The pointer extension 23 is at an angle γ for the straight continuation of a longitudinal extension of the pointer 9 between the pointer tip 11 and pointer shaft 10. This represents a favorable solution, as that so depending on the possibilities of housing or design requirements, the auxiliary scale 16 are housed largely optional can.

Im Gegensatz zur Zeigerspitze 11, die in diesem Beispiel rund gestaltet ist, weist die Spitze 24 der Zeigerverlängerung 23 ebenfalls eine spitz zulaufende Verjüngung auf, die ein genaues Ablesen an der Hilfsskala 16 mit der verkleinerten Skaleneinteilung ermöglicht.In contrast to the pointer tip 11, which in this example is round in shape, the tip 24 of the pointer extension 23 also has a tapered taper, which allows accurate reading on the auxiliary scale 16 with the reduced scale graduation.

So kann mittels Zeigerverlängerung 23 die Zeit nach wie vor an der Hilfsskala 16 exakt abgelesen werden.Thus, by means of pointer extension 23, the time can still be read exactly on the auxiliary scale 16.

Für den Fall, dass es die Größe der Gestaltung des Zifferblattes 3, d.h. die Größe des Fensters, der zusätzlichen Anzeige oder eines Datumsfeldes, was auch immer die Unterbrechung verursacht, zulässt d.h. noch ausreichend Raum zwischen der Unterbrechung 13 und dem Zentrum 8 der Skala 4 ist, kann die Hilfsskala 16 in dem Bereich zwischen Unterbrechung 13 und Zentrum 8 angeordnet sein, wie dies in Fig. 3 dargestellt ist. Damit entfällt eine Spiegelung und Seitenverkehrung bei der Gestaltung der Hilfsskala 16 im Bezug auf den durch die Unterbrechung 13 nicht vorhandenen Teil der Skala 4, wie dies oben dargestellt wurde. Lediglich eine Verkleinerung der Hilfsskala 16 im Vergleich zu dem durch die Unterbrechung 13 verlorenen Skalenteil ist erforderlich.In the event that the size of the design of the dial 3, ie the size of the window, the additional display or a date field, whatever causes the interruption, ie still sufficient space between the interruption 13 and the center 8 of the scale 4 is the auxiliary scale 16 may be arranged in the area between interruption 13 and center 8, as shown in Fig. 3 is shown. This eliminates a reflection and Side reversal in the design of the auxiliary scale 16 with respect to the non-existing by the interruption 13 part of the scale 4, as shown above. Only a reduction of the auxiliary scale 16 in comparison to the lost by the interruption 13 scale part is required.

Durch diese Gestaltung überstreicht der Zeiger 9 ohne eine Zeigerverlängerung die Hilfsskala 16.As a result of this design, the pointer 9 passes over the auxiliary scale 16 without a pointer extension.

Um hierbei die Exaktheit der Anzeige zu erhöhen, ist es zweckmäßig, dass der Zeiger 9 in seinem die Hilfsskala 16 überstreichenden Bereich 25 mit einer Verjüngung versehen ist. Diese Verjüngung hat die gleiche Funktion wie eine verjüngte Zeigerspitze 11, nämlich die Zuordnung zwischen Zeiger 9 und Hilfsskala 16 eindeutig zu finden und damit die Ablesegenauigkeit zu erhöhen.In order to increase the accuracy of the display, it is appropriate that the pointer 9 is provided in its auxiliary scale 16 sweeping area 25 with a taper. This taper has the same function as a tapered pointer tip 11, namely the assignment between pointer 9 and auxiliary scale 16 to find unique and thus increase the reading accuracy.
