Description

Die Erfindung betrifft eine Einzeigeruhr mit einem Uhrwerk und einem einzigen Zeiger. Im Gegensatz zu herkömmlichen Uhren, die die Uhrzeit mit einem Stunden-und einem Minutenzeiger anzeigen, verwenden Einzeigeruhren hierzu nur einen einzigen Zeiger. Während die Motivation zur Verwendung eines einzigen Zeigers ursprünglich in der möglichen Vereinfachung eines mechanischen Uhrwerks gelegen haben mag, ist ein Vorteil von Uhren mit nur einem einzigen Zeiger in der heutigen Zeit vornehmlich in der besonderen Gestaltung der Uhr zu sehen. So gibt die Verwendung eines einzigen Zeigers Raum für eine auf das Wesentliche reduzierte Gestaltung.The invention relates to a single-hand watch with a movement and a single pointer. Unlike traditional watches that show the time with an hour and a minute hand, single-hand watches use only a single hand to do so. While the motivation for using a single pointer may have originally been in the possible simplification of a mechanical timepiece, an advantage of watches with only a single hand at the present time is primarily to be seen in the particular design of the timepiece. So the use of a single pointer gives room for a reduced to the essentials design.

Bekannte Einzeigeruhren weisen in der Regel einen einzigen Zeiger auf, dessen Bewegung derjenigen eines herkömmlichen Stundenzeigers entspricht. Um dennoch eine möglichst genaue Ablesung der Uhrzeit zu ermöglichen, sind unterschiedliche Hilfsmittel vorgeschlagen worden.Known one-hand watches usually have a single pointer whose movement corresponds to that of a conventional hour hand. In order to still allow the most accurate reading of the time, different tools have been proposed.

Beispielsweise zeigt die Druckschrift US 5,280,461 A eine Uhr mit einem Stundenzeiger, in dem ein in Längsrichtung des Stundenzeigers verstellbarer Schieber gelagert ist. An der Position des Schiebers soll eine Minuteninformation ablesbar sein.For example, the document shows US 5,280,461 A a clock with an hour hand, in which an adjustable in the longitudinal direction of the hour hand slider is mounted. At the position of the slider minute information should be readable.

Aus der Druckschrift US 5,134,596 A ist eine Einzeigeruhr bekannt geworden, deren Zifferblatt zwei Skalen aufweist. An einer inneren Skala kann eine Stunden-Information abgelesen werden, an einer äußeren Skala eine Minuten-Information. Dabei weist die äußere Skala eine Teilung in Fünf-Minuten-Intervalle auf.From the publication US 5,134,596 A has become known a one-hand watch whose dial has two scales. Hourly information can be read on an internal scale and minute information on an external scale. The outer scale has a division into five-minute intervals.

Aus der Druckschrift FR 1 422 624 A ist eine Einzeigeruhr bekannt geworden, deren Zifferblatt zusätzlich zu einer Stundenskala treppenförmige Linien aufweist, die ein Ablesen einer Minuten-Information in 15-Minuten-Intervallen ermöglicht.From the publication FR 1 422 624 A For example, a single-hand watch has become known whose dial has stepped lines in addition to an hourly scale, allowing for reading of minute information at 15-minute intervals.

Aus der Druckschrift GB 185 321 A ist eine Einzeigeruhr bekannt geworden, deren Zifferblatt eine besonders feine Skaleneinteilung in Minutenschritten aufweist. Ein spezieller Gewichtsausgleichsmechanismus soll zudem die korrekte Stellung der Zeigerspitze sicherstellen.From the publication GB 185 321 A has become known a one-hand watch whose dial has a particularly fine scale graduation in minutes. A special weight compensation mechanism should also ensure the correct position of the pointer tip.

Andere bekannte Einzeigeruhren haben einen einzigen Zeiger, der in 24 Stunden einmal umläuft, so dass Tag und Nacht unterschieden werden können. Die im Vergleich zu einem in 12 Stunden umlaufenden Zeiger noch langsamere Bewegung des Zeigers erschwert eine genaue Ablesung zusätzlich.Other well-known one-hand watches have a single hand, which rotates once in 24 hours, so that day and night can be distinguished. The even slower movement of the pointer in comparison to a pointer rotating in 12 hours makes an accurate reading even more difficult.

Ein Beispiel ist die in der Druckschrift WO 011/71433 A1 beschriebene Armbanduhr, die die Merkmale des Oberbegriffs des Anspruchs 1 aufweist. Die bekannte Uhr kann mit Hilfe eines Betätigungselements in wechselnde, unterschiedlichen Zeitzonen entsprechende Betriebszustände versetzt werden. Zusätzlich zu dem Zeiger weist sie eine digitale Anzeige für die genaue Uhrzeit einschließlich Minuten und Sekunden auf.An example is the one in the publication WO 011/71433 A1 described wristwatch, having the features of the preamble of claim 1. The known clock can be offset by means of an actuating element in changing, different time zones corresponding operating states. In addition to the pointer, it has a digital display for the exact time, including minutes and seconds.

Ebenfalls bekannt sind Uhren, die getrennt voneinander arbeitende Uhrwerke aufweisen, wobei eines der Uhrwerke einen Stundenzeiger und ein zweites einen Minutenzeiger antreibt. Derartige Uhren sind beispielsweise aus den Druckschriften DE 299 126 24 U1 und DE 20 2008 010 962 U1 bekannt geworden.Also known are watches that have separately working movements, with one of the movements drives an hour hand and a second minute hand. Such watches are for example from the publications DE 299 126 24 U1 and DE 20 2008 010 962 U1 known.

Aus der Druckschrift DE 40 03 655 C1 ist eine Armbanduhr mit einem Minutenzeiger bekannt geworden. Unterhalb des Minutenzeigers rotiert eine Bildscheibe, wobei das Erscheinungsbild des Minutenzeigers von der Stellung der Bildscheibe beeinflusst wird. Dies soll das Ablesen einer Stundeninformation am Minutenzeiger ermöglichen.From the publication DE 40 03 655 C1 a wristwatch with a minute hand has become known. Below the minute hand, an image slice rotates, with the appearance of the minute hand being affected by the position of the image slice. This should allow the reading of an hour information on the minute hand.

Aus der Druckschrift US 2011/0299365 A1 ist eine Uhr mit einem Minutenzeiger und einem Stundenzeiger bekannt geworden. Diese beiden Zeiger zeigen die Uhrzeit in der üblichen Weise an. Durch Drücken eines Knopfs kann der Minutenzeiger in eine andere Stellung gebracht werden, in der er auf einer gesonderten Skala von 1 bis 31 den Tag des aktuellen Datums anzeigt.From the publication US 2011/0299365 A1 a clock with a minute hand and an hour hand has become known. These two hands indicate the time in the usual way. By pressing a button, the minute hand can be moved to another position, displaying the day of the current date on a separate scale from 1 to 31.

Davon ausgehend ist es die Aufgabe der Erfindung, eine Einzeigeruhr zur Verfügung zu stellen, die einfach aufgebaut ist, eine besonders schlichte und elegante Gestaltung ermöglicht und dennoch minutengenau ablesbar ist.On this basis, it is the object of the invention to provide a single-hand watch that is simple in design, allows a particularly simple and elegant design and yet is accurate to the minute read.

Diese Aufgabe wird gelöst durch die Einzeigeruhr mit den Merkmalen des Anspruchs 1. Vorteilhafte Ausgestaltungen sind in den sich anschließenden Unteransprüchen angegeben.This object is achieved by the single-hand watch with the features of claim 1. Advantageous embodiments are specified in the subsequent subclaims.

Die Einzeigeruhr hat

  • einen einzigen Zeiger, der in eine Vielzahl von Zeigerstellungen verstellbar ist,
  • ein Uhrwerk zur mechanischen Verstellung des Zeigers derart, dass sich der Zeiger in einer Zeigerstellung befindet, die einer aktuellen Uhrzeit entspricht, dadurch gekennzeichnet, dass
  • die Einzeigeruhr ein mit dem Uhrwerk verbundenes Betätigungselement aufweist und
  • das Uhrwerk dazu ausgebildet ist, bei Betätigung des Betätigungselements von einem ersten Betriebszustand in einen zweiten Betriebszustand zu wechseln und den Zeiger derart zu verstellen, dass die Zeigerstellung in dem ersten Betriebszustand eine Minuten-Information und in dem zweiten Betriebszustand eine Stunden-Information anzeigt.
The one-hand watch has
  • a single pointer that is adjustable in a variety of pointer positions,
  • a movement for mechanical adjustment of the pointer such that the pointer is in a pointer position corresponding to a current time, characterized in that
  • the one-hand watch has an actuator connected to the movement and
  • the movement is adapted to change upon actuation of the actuating element from a first operating state to a second operating state and to adjust the pointer such that the pointer position in the first operating state indicates a minute information and in the second operating state an hour information.

Der einzige Zeiger kann eine längliche Grundform aufweisen. Er kann an einem Ende oder an einem mittleren Abschnitt drehbar gelagert sein und hierzu insbesondere fest mit einer Drehachse verbunden sein, die drehbar in einem Gehäuse der Einzeigeruhr gelagert ist. Ein von der Drehachse entferntes Ende des Zeigers kann eine Zeigerspitze aufweisen. Die Stellung dieses Endes des Zeigers relativ zu der Drehachse bzw. relativ zu einem Zifferblatt der Einzeigeruhr ermöglicht ein Ablesen der Minuten- bzw. Stunden-Information. Hierzu kann das Zifferblatt wahlweise eine Skalierung aufweisen, beispielsweise in Form von Markierungen in Fünf-Minuten-Intervallen, also an den Positionen der Stundenmarkierungen eines herkömmlichen Zifferblatts mit einer Stundenteilung. Zusätzliche Markierungen am Zifferblatt können die Positionen in Minutenintervallen angeben. Zusätzlich oder alternativ zu den Markierungen kann das Zifferblatt Ziffern aufweisen, beispielsweise von 1 bis 12.The single pointer may have an elongated basic shape. It may be rotatably mounted at one end or at a central portion and in particular be fixedly connected to a rotation axis which is rotatable in a housing the one-hand watch is stored. An end of the pointer remote from the axis of rotation may have a pointer tip. The position of this end of the pointer relative to the axis of rotation or relative to a dial of the one-hand watch allows reading of the minute or hour information. For this purpose, the dial can optionally have a scaling, for example in the form of markings in five-minute intervals, ie at the positions of the hour markers of a conventional dial with an hour division. Additional markings on the dial can indicate the positions at minute intervals. In addition or as an alternative to the markings, the dial can have numerals, for example from 1 to 12.

Der Zeiger ist von dem Uhrwerk mechanisch in eine Vielzahl von Zeigerstellungen verstellbar, wobei im Falle eines drehbar gelagerten Zeigers die Zeigerspitze auf einer Kreisbahn umlaufen kann. Damit die Zeigerstellung stets einer aktuellen Uhrzeit entspricht, verfügt das Uhrwerk über eine Information über die aktuelle Uhrzeit. Hierzu kann das Uhrwerk einen Taktgeber aufweisen, etwa ein Quarz, eine Unruh oder ein Tourbillon.The pointer is mechanically adjustable by the movement into a plurality of pointer positions, wherein in the case of a rotatably mounted pointer, the pointer tip can rotate on a circular path. So that the pointer position always corresponds to a current time, the movement has information about the current time. For this purpose, the movement may have a clock, such as a quartz, a balance or a tourbillon.

Bei der Erfindung weist die Einzeigeruhr ein Betätigungselement auf, das von einem Benutzer der Uhr betätigt werden kann. Bei dem Betätigungselement kann es sich insbesondere um einen Knopf, einen Taster, eine Sensorfläche oder ein Sensorfeld handeln. Dementsprechend kann das Betätigungselement einfach zum Beispiel durch Berührung oder Druck, beispielsweise mit einem Finger, betätigt werden.In the invention, the single-handed watch on an actuator which can be actuated by a user of the clock. The actuating element may in particular be a button, a pushbutton, a sensor surface or a sensor field. Accordingly, the actuator can be easily operated, for example, by touch or pressure, for example with a finger.

Das Uhrwerk weist zwei Betriebszustände auf. In dem ersten Betriebszustand, der auch als Grundzustand bezeichnet werden kann, verstellt das Uhrwerk den Zeiger derart, dass die Zeigerstellung eine Minuteninformation anzeigt. In dem zweiten Betriebszustand, in den das Uhrwerk bei Betätigung des Betätigungselements wechselt, zeigt der einzige Zeiger eine Stunden-Information an.The movement has two operating states. In the first operating state, which may also be referred to as the ground state, the movement adjusts the pointer such that the pointer position indicates minute information. In the second operating state, in which the movement changes upon actuation of the actuator, the only pointer indicates an hour information.

Die Erfindung beruht auf der Erkenntnis, dass bei den meisten Ablesevorgängen einer Uhr die Stunden-Information von untergeordnetem Interesse ist, weil viele Benutzer über diese bereits vor dem Ablesen einer Uhr im Bilde sind. Wichtiger ist häufig die Minuten-Information, etwa um einen kurz bevorstehenden Termin genau einhalten zu können. Folgerichtig haben die Erfinder erkannt, dass es bei einer Einzeigeruhr nicht erforderlich ist, ständig die Stunden-Information anzuzeigen. In dieser Situation ist es für eine genaue und einfache Ablesbarkeit der Uhr von großem praktischen Vorteil, im Grundzustand mit dem einzigen Zeiger die Minuten-Information in einfach und präzise ablesbarer Form darzustellen, anstatt eine ausreichend genaue Ablesbarkeit bei gleichzeitiger Anzeige von Stunden- und Minuten-Information unter Zuhilfenahme komplizierter Hilfsmittel anzustreben, wie bei den eingangs geschilderte, bekannten Einzeigeruhren.The invention is based on the recognition that in most clock readings of a clock, the hour information is of minor interest because many users are already aware of these before reading a clock. Often more important is the minute information, for example to be able to comply exactly with an imminent appointment. Consequently, the inventors have recognized that it is not necessary for a single-hand watch to constantly display the hour information. In this situation, for a precise and simple readability of the clock, it is a great practical advantage to display the minute information in a simple and precise readable form in the ground state with the single pointer, instead of a sufficiently accurate readability with simultaneous display of hourly and minute readings. To seek information with the aid of complicated tools, as in the above-described, known one-hand watches.

Dennoch ist in manchen Situationen eine Ablesbarkeit der Stunden-Information unverzichtbar. Dies wird bei der Erfindung durch den zweiten Betriebszustand berücksichtigt, in dem der einzige Zeiger die Stunden-Information anzeigt.Nevertheless, readability of the hourly information is indispensable in some situations. This is taken into account in the invention by the second operating state in which the single pointer indicates the hour information.

Somit genügt bei der erfindungsgemäßen Einzeigeruhr in den meisten Situationen ein einziger Blick auf die Zeigerstellung, um sich über die aktuelle Uhrzeit zu informieren. Ist hierzu ein Ablesen der Stunden-Information erforderlich, genügt eine einzige Betätigung des Betätigungselements und ein zweiter Blick auf die Uhr.Thus, in the case of the single-hand watch according to the invention, in most situations a single glance at the pointer position is sufficient in order to obtain information about the current time. If this requires reading the hour information, a single actuation of the actuator and a second look at the clock is sufficient.

Ein besonderer Vorteil der Erfindung besteht darin, dass sowohl die Minuten- als auch Stunden-Information besonders einfach ablesbar sind. Insbesondere können diese beiden Informationen in der von herkömmlichen Uhren bekannten Art und Weise dargestellt werden. Ein Benutzer muss sich daher nicht mühsam an eine spezielle Anzeigeform der Einzeigeruhr gewöhnen. Gleichzeitig kann die erfindungsgemäße Einzeigeruhr besonders einfach aufgebaut sein. Wie andere Einzeigeruhren auch benötigt sie nur einen einzigen Zeiger. Zusätzlich unterscheiden sich die Anforderungen an die Präzision der Zeigerbewegung nicht von denen einer herkömmlichen Uhr mit einem Minutenzeiger.A particular advantage of the invention is that both the minute and hour information is particularly easy to read. In particular, these two pieces of information may be in the manner and manner known from conventional watches Be presented manner. A user therefore does not have to get used to a special display mode of the one-hand watch. At the same time, the single-hand watch according to the invention can be constructed particularly simply. Like other single-hand watches, it only needs a single hand. In addition, the requirements for the precision of the pointer movement do not differ from those of a conventional watch with a minute hand.

In einer Ausgestaltung ist das Uhrwerk so ausgebildet, dass genau 60 eindeutig unterscheidbare Zeigerstellungen möglich sind. Diese Zeigerstellungen können im ersten Betriebszustand insbesondere der Minutenteilung eines Zifferblatts einer herkömmlichen Uhr mit einem Minutenzeiger entsprechen. Bei dieser Ausgestaltung sind zwischen diesen Minuten-Positionen befindliche Zeigerstellungen nicht möglich; vielmehr springt der Zeiger von einer Zeigerstellung zur nächsten. Dadurch ist zu jedem Zeitpunkt zweifelsfrei erkennbar, welcher Minute die aktuelle Zeigerstellung entspricht.In one embodiment, the movement is designed so that exactly 60 clearly distinguishable pointer positions are possible. These pointer positions can correspond in the first operating state, in particular the minute division of a dial of a conventional clock with a minute hand. In this embodiment, located between these minute positions pointer positions are not possible; rather, the pointer jumps from one pointer position to the next. This makes it clear at any time, no matter which minute corresponds to the current pointer position.

In einer Ausgestaltung ist das Uhrwerk so ausgebildet, dass im zweiten Betriebszustand genau zwölf eindeutig unterscheidbare Zeigerstellungen möglich sind. Diese zwölf Zeigerstellungen können insbesondere den Stellungen eines Stundenzeigers einer herkömmlichen Uhr jeweils zur vollen Stunde entsprechen. Im zweiten Betriebszustand verstellt das Uhrwerk den Zeiger so, dass der Zeiger jeweils exakt eine der zwölf Zeigerstellungen einnimmt. Zwischenstellungen sind nicht möglich. Dadurch unterscheidet sich die Zeigerstellung im zweiten Betriebszustand von der Zeigerstellung eines herkömmlichen Stundenzeigers, der in der Regel kontinuierlich umläuft und auch Zwischenstellungen zwischen seinen Positionen zu zwei aufeinanderfolgenden, vollen Stunden einnimmt. Dies ist für ein zweifelsfreies Ablesen der Stunden-Information von Vorteil.In one embodiment, the movement is designed so that in the second operating state exactly twelve clearly distinguishable pointer positions are possible. These twelve pointer positions can in particular correspond to the positions of an hour hand of a conventional clock in each case at the full hour. In the second operating state, the movement adjusts the pointer so that the pointer occupies exactly one of the twelve pointer positions. Intermediate positions are not possible. As a result, the pointer position in the second operating state differs from the pointer position of a conventional hour hand, which usually rotates continuously and also occupies intermediate positions between its positions to two consecutive full hours. This is an advantage for a clear reading of the hour information.

In einer Ausgestaltung weist das Uhrwerk ein elektromechanisches Stellglied zur Verstellung des Zeigers auf. Grundsätzlich kann die Einzeigeruhr auch mit einem mechanischen Uhrwerk ausgestattet sein, das als Energiespeicher beispielsweise eine Feder verwendet. Bevorzugt weist die Einzeigeruhr jedoch ein elektromechanisches Stellglied auf, das den Zeiger verstellt, beispielsweise einen Schrittmotor. Als Energiespeicher kann die Einzeigeruhr eine Batterie aufweisen. Ein elektromechanisches Stellglied kann besonders einfach in der gewünschten Weise angesteuert werden.In one embodiment, the movement on an electromechanical actuator for adjusting the pointer. In principle, the single-hand watch can also be equipped with a mechanical movement that uses, for example, a spring as an energy store. However, the single-hand watch preferably has an electromechanical actuator which adjusts the pointer, for example a stepper motor. As an energy store, the single-hand watch may have a battery. An electromechanical actuator can be controlled particularly easily in the desired manner.

In einer Ausgestaltung ist das Uhrwerk ein elektronisches Uhrwerk. Dabei kann es sich insbesondere um ein Quarzuhrwerk handeln, das als Zeitbasis ein Schwingquarz verwendet. Ebenfalls geeignet ist ein Funkuhrwerk, das eine Antenne aufweist, mit der ein per Funk ausgestrahltes Zeitsignal empfangen wird. Auch in diesen Fällen kann die Einzeigeruhr als Energiespeicher eine Batterie aufweisen. Das elektronische Uhrwerk kann eine Steuerung aufweisen, die eine Zeitinformation und ein Signal von dem Betätigungselement verarbeitet und in geeignete Steuersignale für einen elektromechanisches Stellglied für den Zeigers umsetzt.In one embodiment, the movement is an electronic movement. This may in particular be a quartz movement, which uses a quartz crystal as the time base. Also suitable is a radio movement, which has an antenna with which a radio-broadcast time signal is received. Even in these cases, the single-hand watch can have a battery as energy storage. The electronic timepiece may include a controller that processes time information and a signal from the actuator and converts them into appropriate control signals for an electromechanical actuator for the pointer.

In einer Ausgestaltung weist die Einzeigeruhr ein Armband auf. In diesem Fall handelt es sich um eine Einzeiger-Armbanduhr. Grundsätzlich kann die Einzeigeruhr auch als Stand- oder Wanduhr oder sonstige mobile Uhr, etwa als Taschenuhr, ausgebildet sein.In one embodiment, the one-hand watch on a bracelet. In this case, it is a one-hand watch. In principle, the single-hand watch can also be designed as a standing or wall clock or other mobile clock, such as a pocket watch.

In einer Ausgestaltung ist das Uhrwerk dazu ausgebildet, nach Betätigung des Betätigungselements automatisch in den ersten Betriebszustand zurück zu wechseln. Beispielsweise kann der zweite Betriebszustand, in den die Steuerung bei Betätigung des Betätigungselements wechselt, nur so lange beibehalten werden, wie das Betätigungselement betätigt wird. Anschließend, also nach Betätigung des Betätigungselements, kann die Steuerung automatisch in den ersten Betriebszustand zurückwechseln, sodass wieder die Minuten-Information angezeigt wird.In one embodiment, the movement is designed to automatically switch back to the first operating state after actuation of the actuating element. For example, the second operating state, in which the control changes upon actuation of the actuating element, can be maintained only as long as the actuating element is actuated. Then, after pressing the Actuator, the controller can automatically switch back to the first operating state, so that the minute information is displayed again.

In einer Ausgestaltung ist die Steuerung dazu ausgebildet, nach Betätigung des Betätigungselements für einen vorgegebenen Zeitraum in dem zweiten Betriebszustand zu verbleiben. Der vorgegebene Zeitraum kann insbesondere im Bereich von einer Sekunde bis zehn Sekunden betragen, vorzugsweise im Bereich von zwei bis fünf Sekunden, insbesondere etwa drei Sekunden. In diesem Fall ist es unerheblich, wie lange das Betätigungselement betätigt wird. Nach jeder Betätigung verbleibt die Steuerung für einen Zeitraum in dem zweiten Betriebszustand, der für ein zuverlässiges Ablesen der Stunden-Information ausreichend ist. Anschließend kann automatisch zur Anzeige der Minuten-Information zurückgewechselt werden.In one embodiment, the controller is designed to remain in the second operating state for a predetermined period of time after actuation of the actuating element. In particular, the predetermined period may be in the range of one second to ten seconds, preferably in the range of two to five seconds, in particular about three seconds. In this case, it does not matter how long the actuator is actuated. After each operation, the controller remains in the second operating state for a period sufficient for reliable reading of the hour information. You can then switch back to the minute information display automatically.

In einer Ausgestaltung ist das Uhrwerk dazu ausgebildet, bei zweimaliger Betätigung des Betätigungselements in einen dritten Betriebszustand zu wechseln und den Zeiger derart zu verstellen, dass die Zeigerstellung in dem dritten Betriebszustand eine Sekunden-Information anzeigt. Insbesondere kann der Wechsel in den dritten Betriebszustand erfolgen, wenn die zweimalige Betätigung des Betätigungselements innerhalb eines bestimmten Zeitraums erfolgt. Insbesondere kann eine zweimalige Betätigung des Betätigungselements darin bestehen, dass die zweite Betätigung zu einem Zeitpunkt erfolgt, in dem sich das Uhrwerk noch aufgrund der ersten Betätigung des Betätigungselements in dem zweiten Betriebszustand befindet. In diesem Fall wechselt das Uhrwerk in den dritten Betriebszustand. Erfolgt keine weitere Betätigung des Betätigungselements, kann das Uhrwerk automatisch in den ersten Betriebszustand zurückwechseln, insbesondere so, wie im Zusammenhang mit dem automatischen Wechsel vom zweiten in den ersten Betriebszustand erläutert. Die Ausgestaltung ermöglicht ein einfaches und genaues Ablesen einer Sekunden-Information, ohne dass hierfür ein weiteres Anzeigeelement benötigt wird.In one embodiment, the movement is designed to change to two operating the actuator in a third operating state and to adjust the pointer so that the pointer position in the third operating state indicates a second information. In particular, the change to the third operating state can take place if the two-time actuation of the actuating element takes place within a certain period of time. In particular, a two-time operation of the actuating element may consist in that the second actuation takes place at a time in which the movement is still in the second operating state due to the first actuation of the actuating element. In this case, the movement changes to the third operating state. If no further actuation of the actuating element, the movement can automatically switch back to the first operating state, in particular as explained in connection with the automatic change from the second to the first operating state. The design allows a simple and accurate reading of a Seconds information without the need for another display element.

In einer Ausgestaltung ist das Uhrwerk dazu ausgebildet, bei dreimaliger Betätigung des Betätigungselements in einen vierten Betriebszustand zu wechseln und den Zeiger derart zu verstellen, dass die Zeigerstellung in dem vierten Betriebszustand eine Tages-Information anzeigt. Die Tages-Information bezieht sich auf den Tag des aktuellen Datums.In one embodiment, the movement is adapted to change to three times operation of the actuating element in a fourth operating state and to adjust the pointer such that the pointer position in the fourth operating state displays a daily information. The day information refers to the day of the current date.

In einer Ausgestaltung ist das Uhrwerk dazu ausgebildet, bei viermaliger Betätigung des Betätigungselements in einen fünften Betriebszustand zu wechseln und den Zeiger derart zu verstellen, dass die Zeigerstellung in dem fünften Betriebszustand eine Monats-Information anzeigt. Die Monats-Information bezieht sich auf das aktuelle Datum.In one embodiment, the movement is adapted to change to a fifth operating state with four actuation of the actuating element and to adjust the pointer such that the pointer position in the fifth operating state indicates a month information. The monthly information refers to the current date.

In einer Ausgestaltung ist das Uhrwerk dazu ausgebildet, bei fünfmaliger Betätigung des Betätigungselements in einen sechsten Betriebszustand zu wechseln und den Zeiger derart zu verstellen, dass die Zeigerstellung in dem sechsten Betriebszustand eine Jahres-Information anzeigt. Die Jahres-Information bezieht sich auf das aktuelle Datum. Die erläuterten Ausgestaltungen erlauben ein einfaches Ablesen von Datums-Informationen, ohne das hierzu ein gesondertes Anzeigeelement benötigt wird. Für das Vorliegen einer mehrmaligen Betätigung des Betätigungselements gelten die vorstehenden Erläuterungen zu der zweimaligen Betätigung entsprechend. Gleiches gilt für den stets möglichen, automatischen Wechsel vom dritten, vierten, fünften bzw. sechsten Betriebszustand zurück in den ersten Betriebszustand, der wie in Verbindung mit dem Wechsel vom zweiten Betriebszustand in den ersten Betriebszustand ausgestaltet werden kann.In one embodiment, the movement is designed to change to five operating the actuator in a sixth operating state and to adjust the pointer so that the pointer position in the sixth operating state displays an annual information. The year information refers to the current date. The illustrated embodiments allow easy reading of date information, without the need for a separate display element is required. For the presence of a repeated operation of the actuating element, the above explanations apply to the two-time operation accordingly. The same applies to the always possible, automatic change from the third, fourth, fifth or sixth operating state back into the first operating state, which can be configured as in connection with the change from the second operating state to the first operating state.

In einer Ausgestaltung ist das Uhrwerk dazu ausgebildet, den Zeiger bei einem Wechsel des Betriebszustands, der von dem ersten Betriebszustand ausgeht, stets im Uhrzeigersinn zu verstellen und bei einem Wechsel des Betriebszustands, der in den ersten Betriebszustand zurückführt, stets entgegen dem Uhrzeigersinn zu verstellen oder umgekehrt. Ein Wechsel, der von dem ersten Betriebszustand ausgeht, kann insbesondere ein Wechsel von dem ersten Betriebszustand in den zweiten Betriebszustand sein, aber auch ein Wechsel vom ersten Betriebszustand in den dritten, vierten, fünften oder sechsten Betriebszustand, wie er sich bei mehrmaliger Betätigung des Betätigungselements ergibt. Ein Wechsel, der in den ersten Betriebszustand zurückführt, kann insbesondere ein Wechsel von dem zweiten Betriebszustand in den ersten Betriebszustand sein, aber auch ein Wechsel vom dritten, vierten, fünften oder sechsten Betriebszustand zurück in den ersten. Mit "oder umgekehrt" ist gemeint, dass der Zeiger bei einem vom ersten Betriebszustand ausgehenden Wechsel entgegen dem Uhrzeigersinn und bei einem zu dem ersten Betriebszustand zurückführenden Wechsel im Uhrzeigersinn verstellt wird. Der unterschiedliche Drehsinn erleichtert das Ablesen der Uhr, weil bei Wahrnehmung einer bestimmten Drehrichtung sogleich ersichtlich ist, ob die nachfolgende Zeigerdarstellung einem der weiteren Betriebszustände entspricht, also z.B. die Stunden-Information ablesbar ist, oder ob bereits der Wechsel zurück zur Minutenanzeige erfolgt ist.In one embodiment, the movement is designed to always adjust the pointer in a clockwise change in the operating state, which starts from the first operating state and always to adjust counterclockwise when changing the operating state, which leads back to the first operating state vice versa. A change, which starts from the first operating state, may in particular be a change from the first operating state to the second operating state, but also a change from the first operating state to the third, fourth, fifth or sixth operating state, as occurs when the actuating element is actuated several times results. A change, which leads back to the first operating state, may in particular be a change from the second operating state to the first operating state, but also a change from the third, fourth, fifth or sixth operating state back to the first. By "or vice versa" it is meant that the pointer is adjusted counterclockwise at a change from the first operating state and in a clockwise direction returning to the first operating state. The different sense of rotation facilitates the reading of the clock, because it is readily apparent when perceiving a particular direction of rotation, whether the subsequent pointer representation corresponds to one of the other operating states, eg. the hour information is readable, or whether the change back to the minutes has already occurred.

Die Einzeigeruhr 10 aus Fig. 1 weist ein Gehäuse 12 und ein Zifferblatt 14 auf. Das Zifferblatt 14 weist eine Skala mit zwölf Skalenmarkierungen in Form von Teilstrichen 16 auf, die an den Positionen angeordnet sind, die ein Stundenzeiger einer herkömmlichen Uhr zur jeweils vollen Stunde einnimmt. Außerdem hat die Einzeigeruhr 10 ein Armband 18, das an dem Gehäuse 12 befestigt ist.The one-hand watch 10 off Fig. 1 has a housing 12 and a dial 14. The dial 14 has a scale with twelve scale marks in the form of graduations 16, which are arranged at the positions that occupies an hour hand of a conventional clock on the hour. In addition, the single-hand watch 10 has a bracelet 18 which is fixed to the housing 12.

Die Einzeigeruhr 10 weist einen einzigen Zeiger 20 auf mit einer Zeigerspitze 22. Der Zeiger 20 ist um eine Drehachse 24 drehbar gelagert, sodass die Zeigerspitze 22 auf einer Kreisbahn umläuft. An der rechten Seite des Gehäuses 12 befindet sich ein Betätigungselement 26 in Form eines Druckknopfs.The single-hand watch 10 has a single pointer 20 with a pointer tip 22. The pointer 20 is rotatably mounted about an axis of rotation 24, so that the pointer tip 22 rotates in a circular path. On the right side of the housing 12 is an actuator 26 in the form of a push button.

Im Inneren der Einzeigeruhr 10 angeordnete Elemente sind gestrichelt eingezeichnet. Dabei handelt es sich um Uhrwerk, das einen Schrittmotor 28 aufweist, der einen Verstellantrieb für den Zeiger 20 bildet, mit dem der Zeiger 20 zwischen einer Vielzahl von unterschiedlichen Zeigerstellungen verstellbar ist. Das Uhrwerk weist weiterhin eine elektronische Steuerung 30 auf, die den Schrittmotor 28 ansteuert. Über eine erste elektrische Leitung 32 ist die elektronische Steuerung 30 mit dem Schrittmotor 28 verbunden. Über eine zweite elektrische Leitung 34 ist sie mit dem Betätigungselement 26 verbunden.Inside the one-hand watch 10 arranged elements are shown in dashed lines. It is clockwork having a stepper motor 28 which forms an adjustment for the pointer 20, with which the pointer 20 is adjustable between a plurality of different pointer positions. The movement also has an electronic control 30, which controls the stepper motor 28. Via a first electrical line 32, the electronic controller 30 is connected to the stepper motor 28. Via a second electrical line 34, it is connected to the actuating element 26.

Alle unterschiedlichen Betriebszustände der Einzeigeruhr 10 werden beispielhaft zu der Uhrzeit 8:10:51 Uhr und dem Datum 30. Mai 2013 erläutert. Fig. 1 zeigt den ersten Betriebszustand, der auch als Grundzustand bezeichnet werden kann. In diesem ersten Betriebszustand zeigt der Zeiger 20 eine Minuten-Information an. Der Zeiger 20 steht in einer Zeigerstellung, die bei einem Minutenzeiger einer herkömmlichen Uhr der 10-Minuten-Position entspricht. Es wird also die Minuten-Information "10" dargestellt.All different operating states of the one-hand watch 10 are explained by way of example at the time 8:10:51 and the date 30 May 2013. Fig. 1 shows the first operating state, which can also be referred to as the ground state. In this first operating state, the pointer 20 displays minute information. Of the Pointer 20 is in a hand position, which corresponds to a minute hand of a conventional clock of the 10-minute position. Thus, the minute information "10" is displayed.

Wird ausgehend von dem ersten Betriebszustand der Fig. 1 das Betätigungselement 26 einmal betätigt, wechselt das Uhrwerk bzw. die Steuerung 30 in den zweiten Betriebszustand, der in der Fig. 2 dargestellt ist. In diesem zweiten Betriebszustand stellt das Uhrwerk den Zeiger 20 in eine Zeigerstellung, die bei einem Minutenzeiger einer herkömmlichen Uhr der Acht-Minuten-Position entspricht. Dadurch wird die Stundeninformation "acht" dargestellt. Erfolgt im zweiten Betriebszustand keine weitere Betätigung des Betätigungselements 26, wechselt das Uhrwerk automatisch in den in der Fig. 1 gezeigten, ersten Betriebszustand zurück und stellt in der Folge die Minuten-Information dar.Is starting from the first operating state of Fig. 1 actuates the actuator 26 once, the movement or the controller 30 changes to the second operating state, in the Fig. 2 is shown. In this second operating state, the movement sets the pointer 20 in a pointer position, which corresponds to the eight-minute position at a minute hand of a conventional clock. As a result, the hour information "eight" is displayed. If, in the second operating state, no further actuation of the actuating element 26 occurs, the movement automatically changes to the one in the Fig. 1 shown, first operating state and represents the minute information in the sequence.

Erfolgt allerdings eine zweimalige Betätigung des Betätigungselements 26, wechselt die Steuerung 30 in den in der Fig. 3 gezeigten, dritten Betriebszustand. In diesem dritten Betriebszustand wird der Zeiger 20 in eine Zeigerstellung verstellt, die bei einem Minutenzeiger einer herkömmlichen Uhr der 51-Minuten-Position entspricht. Da sich die Einzeigeruhr 10 im dritten Betriebszustand befindet, in dem die Sekunden-Information dargestellt wird, bedeutet dies, dass die aktuelle Sekunden-Information "51" lautet ist.However, if a two-time operation of the actuator 26, the controller 30 changes in the in the Fig. 3 shown, third operating state. In this third operating state, the pointer 20 is moved to a pointer position, which corresponds to a minute hand of a conventional clock of the 51-minute position. Since the one-hand watch 10 is in the third operation state in which the second information is displayed, it means that the current second information is "51".

Bei einer dreimaligen Betätigung des Betätigungselements 26 ergibt sich der in der Fig. 4 dargestellte, vierte Betriebszustand. Der Zeiger 20 wird in die 30-Minuten-Position verstellt, was einer Darstellung des Tages "30" entspricht.In a three-time operation of the actuator 26 results in the Fig. 4 illustrated, fourth operating state. The pointer 20 is moved to the 30-minute position, which corresponds to a representation of the day "30".

Bei einer viermaligen Betätigung des Betätigungselements 26 wechselt das Uhrwerk in den in der Fig. 5 dargestellten, fünften Betriebszustand, in dem der Zeiger 20 die "5-Minuten-Position" einnimmt. Dies entspricht dem Kalendermonat Mai.In a four-time operation of the actuator 26, the movement changes in the in the Fig. 5 illustrated, fifth operating state in which the pointer 20 assumes the "5-minute position". This corresponds to the calendar month of May.

Bei einer fünfmaligen Betätigung des Betätigungselements 26 wechselt das Uhrwerk in den sechsten Betriebszustand, der in der Fig. 6 dargestellt ist. Der Zeiger 20 wird in die "13-Minuten-Position" verstellt, was einer Darstellung der Jahreszahl "13" entspricht.In a five-time operation of the actuator 26, the movement changes to the sixth operating state, in the Fig. 6 is shown. The pointer 20 is moved to the "13-minute position", which corresponds to a representation of the year "13".
