The time cycle to be displayed is divided into the same number of sections, and these are applied along the scale sections in opposite directions. The pointer (6) is moved evenly along a path parallel to the scale sections, and direction of movement of the pointer reverses when each end of a scale section is reached.

Description

Die Erfindung betrifft eine Zeitanzeigevorrichtung mit einer Skala und einem Zeiger.The invention relates to a time display device with a scale and a pointer.

Gattungsgemäße Anzeigevorrichtungen sind seit langem bekannt und werden z. B. zur Anzeige der Tageszeit verwendet. Bei einer klassischen Uhr mit analoger Anzeige erfolgt die Anzeige anhand einer kreisförmigen Skala, auf der in bekannter Weise die 12 Stunden entlang des Umfangs aufgetragen sind. Die aktuelle Uhrzeit wird dabei mit Hilfe zweier sich um den Kreismittelpunkt bewegender, unterschiedlich langer Zeiger angezeigt. Diese Darstellung erlaubt dem geübten Betrachter das schnelle Ablesen der Uhrzeit, bei dem nur die Stellung der Zeiger wahrgenommen wird, die Zahlen selbst jedoch nahezu unbeachtet bleiben.Generic display devices have long been known and z. B. used to display the time of day. In a classic watch with an analog display, the display is based on a circular scale, on which in a known manner, the 12 hours along the circumference are applied. The current time is displayed with the aid of two hands of different lengths moving around the center of the circle. This presentation allows the experienced viewer to quickly read the time, in which only the position of the hands is perceived, the numbers themselves, however, remain almost unnoticed.

Nachteilig an dieser Darstellung ist der für eine kreisförmige Skala notwendige Platzbedarf.The disadvantage of this representation is the space required for a circular scale space.

Ebenfalls bekannt ist die Tageszeitanzeige über Digitalanzeige. Eine solche Anzeige bietet zum einen den Vorteil des geringen Platzbedarfs, zum anderen werden die bei Zeigeranzeigen unvermeidlichen Ablesefehler vermieden. Nachteilig gegenüber einer analogen Anzeige ist jedoch die fehlende graphische Darstellung, die ein schnelles Ablesen ermöglicht.Also known is the time of day display via digital display. On the one hand, such a display offers the advantage of the small footprint, on the other hand, the reading errors that are unavoidable with pointer displays are avoided. However, a disadvantage in comparison with an analogue display is the lacking graphical representation, which makes a quick reading possible.

Damit stellt sich die Aufgabe, eine Anzeige vorzuschlagen, die zumindest in einer Ausdehnungsrichtung weniger Platz benötigt und ein schnelles graphisches Ablesen ermöglicht.This raises the task of proposing a display that requires less space, at least in one expansion direction and allows a quick graphical reading.

Dokument DE 202 06 965 U offenbart eine Uhr mit zwei geraden und parallel verlaufenden Skalenabschnitten.document DE 202 06 965 U discloses a clock with two straight and parallel scale sections.

Diese Aufgabe wird bei einer gattungsgemäßen Vorrichtung nach Anspruch 1 gelöst.This object is achieved in a generic device according to claim 1.

Bei dieser Anordnung ist die Anzeigeskala in eine gerade Anzahl gleich langer Abschnitte unterteilt, die parallel zueinander und nebeneinander angeordnet sind. Ebenso ist der Zeitzyklus, innerhalb dessen die Zeit angezeigt wird, in die gleiche Anzahl gleich langer Abschnitte unterteilt. Jeder dieser Zeitabschnitte ist entlang eines Skalenabschnitts aufgetragen, wobei der erste Zeitabschnitt in einer ersten Richtung entlang eines ersten Skalenabschnitts und der zweite Zeitabschnitt entlang eines zweiten Skalenabschnitts in entgegengesetzter Richtung aufgetragen sind. Jeder weitere Zeitabschnitt ist entsprechend entlang eines weiteren Skalenabschnitts aufgetragen, wobei die Richtung jeweils entgegengesetzt zum vorhergehenden Abschnitt ist. Der Zeiger wird auf einer zu den Skalenabschnitten parallelen Bahn gleichförmig bewegt, wobei sich die Bewegungsrichtung des Zeigers jeweils umkehrt, sobald das Ende eines Skalenabschnitts erreicht ist. Dem entsprechend läuft der Zeiger an den nebeneinander liegenden Skalenabschnitten hin und her und zeigt die in dem Zeitzyklus bereits verstrichene bzw. noch verbleibende Zeitdauer graphisch so an, dass diese schnell abzulesen ist. Insbesondere können hiermit schnell abzulesende, graphische Zeitanzeigevorrichtungen, beispielsweise für wissenschaftliche Anwendungen, realisiert werden, deren Zyklusdauer nicht den zwölf Stunden einer klassischen Uhr entspricht und für deren Darstellung eine klassische Rundanzeige verwirrend wäre.In this arrangement, the display scale is divided into an even number of equal length sections, which are arranged parallel to each other and side by side. Likewise, the time cycle within which the time is displayed is divided into the same number of equally long sections. Each of these time segments is plotted along a scale section, the first time segment being plotted in a first direction along a first scale segment and the second segment being plotted along a second scale segment in the opposite direction. Each further time segment is correspondingly plotted along a further scale section, the direction being opposite to the preceding section in each case. The pointer is moved uniformly on a path parallel to the scale sections, with the direction of movement of the pointer reversing each time the end of a scale section is reached. Accordingly, the pointer runs back and forth on the adjacent scale sections and graphically displays the time period that has already passed or remains in the time cycle such that it can be read off quickly. In particular, this can be used to realize fast-reading, graphic time display devices, for example for scientific applications, whose cycle duration does not correspond to the twelve hours of a classical clock and for the presentation of which a classic circular display would be confusing.

Die Erfindung kann insbesondere dadurch weitergebildet sein, dass die Zykluszeit 24 oder 12 Stunden oder 60 Minuten oder 60 Sekunden beträgt. Bei einer Zykluszeit von 24 Stunden, die in zwei Zeitabschnitte geteilt und von denen ein Zeitabschnitt in einer Richtung entlang eines Skalenabschnitts und der andere Zeitabschnitt in entgegengesetzter Richtung an einem zweiten, parallel und daneben verlaufenden Skalenabschnitt aufgetragen ist, lassen sich die ersten 12 Stunden eines Tages an dem ersten Skalenabschnitt und die Stunden der zweiten Tageshälfte an dem zweiten Skalenabschnitt ablesen. Ebenso können kleinere Zeitzyklen entsprechend in Zeitabschnitte aufgeteilt und an den Skalenabschnitten aufgetragen werden.In particular, the invention can be developed in that the cycle time is 24 or 12 hours or 60 minutes or 60 seconds. With a cycle time of 24 hours, divided into two time periods and one time period in one direction along one scale segment and the other period in the opposite direction at a second, parallel and adjacent scale portion, the first 12 hours of a day can be taken at the first scale section and the hours of the second half of the day at the second scale section. Likewise, smaller time cycles can be correspondingly divided into time segments and applied to the scale sections.

Nach einem weiteren Vorschlag kann die Zeitanzeigevorrichtung auch dadurch gekennzeichnet sein, dass parallel zu den Skalenabschnitten und neben diesen eine gleichförmig angetriebene Welle vorgesehen ist, die neben den Skalenabschnitten einen Gewindeabschnitt aufweist, auf dem ein den Zeiger tragendes Gewindeelement läuft. Die Welle selbst wird dabei beispielsweise von einem Elektromotor oder einem herkömmlichen mechanischen oder elektrischen Uhrwerk angetrieben. Über den Gewindeabschnitt der Welle wird die Rotationsbewegung wie bei einem Schneckenantrieb auf ein Gewindeelement übertragen, welches entsprechend eine translatorische Bewegung parallel zur Welle erfährt. Damit wird der Zeiger, der im Gewindeelement sitzt, translatorisch entlang der Wellenachse bewegt.According to a further proposal, the time display device can also be characterized in that parallel to the scale sections and adjacent to this a uniformly driven shaft is provided, which in addition to the scale sections has a threaded portion on which a pointer carrying threaded element runs. The shaft itself is driven, for example, by an electric motor or a conventional mechanical or electric movement. About the threaded portion of the shaft, the rotational movement is transmitted to a threaded member as in a worm drive, which undergoes a translational movement parallel to the shaft accordingly. Thus, the pointer, which sits in the threaded element, translationally moves along the shaft axis.

Die Erfindung kann weiterhin dadurch gekennzeichnet sein, dass die Drehrichtung der Welle immer gleich ist, dass der Gewindeabschnitt über seine gesamte Länge sowohl ein Rechts- als auch ein Linksgewinde aufweist, dass die Gewindegänge des Rechtsund Linksgewindes am Ende des Gewindeabschnitts ineinander übergehen, und dass das in die Wellengewinde eingreifende Führungselement des Gewindeelements bewegbar gelagert ist und bei Erreichen eines jeden Gewindeendes den ineinander übergehenden Gewindegängen folgt. Der Gewindeabschnitt der Welle weist somit über seine gesamte Länge sowohl ein Rechts- als auch ein Linksgewinde auf. Das mit der Welle angetriebene Gewindeelement greift mit einem Führungselement entweder in den Gewindegang des Rechts- oder des Linksgewindes ein. Das Führungselement des Gewindeelements umfasst dabei nur ein Teil des 360° Gewindeganges und ist drehbar gelagert. Bei Erreichen des Endes des Rechts- oder Linksgewindes folgt das Führungselement den ineinander übergehenden Gewindegängen des Rechts- und Linksgewindes und kehrt damit seine Steigung um. Damit läuft das Gewindeelement entlang des Gewindeabschnitts bei gleich bleibender Drehrichtung der Welle hin und her.The invention may further be characterized in that the direction of rotation of the shaft is always the same, that the threaded portion has both a right and a left thread over its entire length, that the threads of the right and left threads at the end of the threaded portion merge into each other, and that the in the shaft thread engaging guide element of the threaded element is movably mounted and upon reaching each end of the thread follows the merging threads. The threaded portion of the shaft thus has over its entire length both a right-hand and a left-hand thread. The driven with the shaft threaded member engages with a guide element either in the thread of the right-hand or left-hand thread. The guide element of the threaded element thereby comprises only a part of the 360 ° thread turn and is rotatably mounted. Upon reaching the end of the right-hand or left-hand thread, the guide element follows the intertwining threads of the right-hand and left-hand thread and thus reverses its pitch. Thus, the threaded element runs along the threaded portion with the same direction of rotation of the shaft back and forth.

Alternativ zu dieser Ausführung von Gewinde und Gewindeelement kann die Vorrichtung auch so ausgeprägt sein, dass das Gewinde der Welle sowie des Gewindeelements entweder ein Rechts- oder Linksgewinde ist, und dass sich die Drehrichtung der Welle umkehrt, sobald das Gewindeelement ein Ende des Wellengewindes erreicht. Die Umkehrung der Drehrichtung kann beispielsweise dadurch bewirkt werden, dass das Gewindeelement bei Erreichen des Wellengewindes einen Schalter auslöst, der die Umkehrung der Drehrichtung der Welle bewirkt. Insbesondere in dem Falle, dass die Welle von einem Elektromotor angetrieben ist, ist dies eine einfache Lösung zur Richtungsumkehr des Gewindeelements.As an alternative to this embodiment of thread and threaded element, the device can also be so pronounced that the thread of the shaft and the threaded member is either a right or left hand thread, and that reverses the direction of rotation of the shaft as soon as the threaded member reaches one end of the shaft thread. The reversal of the direction of rotation can for example be effected by the Threaded element when reaching the shaft thread triggers a switch that causes the reversal of the direction of rotation of the shaft. In particular, in the case that the shaft is driven by an electric motor, this is a simple solution for reversing the direction of the threaded element.

Die Vorrichtung kann auch dadurch weitergebildet sein, dass das Gewindeelement eine von seiner Laufrichtung abhängige Richtungsanzeige aufweist. Hiermit wird beim Ablesen die Zuordnung des Zeigers zu dem zugehörigen Skalenabschnitt erleichtert.The device can also be further developed in that the threaded element has a dependent of its direction direction indicator. This facilitates the assignment of the pointer to the associated scale section during reading.

Weiterhin kann die Vorrichtung auch dadurch gekennzeichnet sein, dass die Welle in der von den Skalenabschnitten aufgespannten Ebene vorgesehen ist. insbesondere bei mechanischen Uhren ist aus ästhetischen Gesichtspunkten häufig die Darstellung der Mechanik gewünscht.Furthermore, the device can also be characterized in that the shaft is provided in the plane defined by the scale sections plane. especially in mechanical watches the appearance of the mechanics is often desired from an aesthetic point of view.

Alternativ dazu kann die Vorrichtung in vorteilhafter Weise auch so ausgebildet sein, dass die Welle unterhalb der von den Skalenabschnitten aufgespannten Ebene vorgesehen ist. Diese Anordnung der Welle unterhalb der Skala erlaubt somit eine besonders schmale Ausführungsform der Antriebsmechanik.Alternatively, the device may advantageously also be designed such that the shaft is provided below the plane spanned by the scale sections. This arrangement of the shaft below the scale thus allows a particularly narrow embodiment of the drive mechanism.

Die Vorrichtung kann auch dadurch weitergebildet sein, dass die Welle mehrere, jeweils begrenzte Abschnitte aufweist, die jeweils über die gesamte Länge sowohl ein Rechtsals auch ein Linksgewinde jeweils zum Antrieb eines Gewindeelementes aufweisen. Bei dieser Ausführungsform können somit über eine Welle mehrere Gewindeelemente bewegt werden. Dabei können die Gewinde in den einzelnen Gewindeabschnitten unterschiedliche Steigungen aufweisen, so dass die Gewindeelemente mit unterschiedlichen Geschwindigkeiten jeweils entlang ihrer Gewindeabschnitte hin- und herlaufen. Beispielsweise könnte mit einer Welle in einem Abschnitt eine Stundenanzeige, und in einem weiteren Abschnitt mit einer Gewindesteigung eine Minutenanzeige realisiert werden.The device can also be further developed in that the shaft has a plurality of respectively limited sections, each of which has both a right and a left-hand thread over the entire length for driving a threaded element. In this embodiment, a plurality of threaded elements can thus be moved via a shaft. The threads in the individual threaded sections may have different pitches, so that the threaded elements reciprocate at different speeds along their threaded sections. For example, with one shaft in one section, an hour indication could be realized, and in another section with a thread pitch, a minute indication could be realized.

Im Folgenden wird die Erfindung anhand eines Ausführungsbeispiels beschrieben.In the following the invention will be described with reference to an embodiment.

Fig. 1 zeigt eine Aufsicht auf eine erfindungsgemäße Zeitanzeigevorrichtung, bei der die 24 Stunden eines Tages in zwei Zeitabschnitte aufgeteilt sind, die entlang des Skalenabschnitts 1 in der einen Richtung und des Skalenabschnitts 2 in der entgegengesetzten Richtung aufgetragen sind. Parallel zu und neben den Skalenabschnitten 1, 2 ist eine Welle 3, die von einem nicht dargestellten Antriebselement 8 angetrieben ist. Der Gewindeabschnitt 4 der Welle 3 weist über seine gesamte Länge sowohl ein Rechts- als auch ein Linksgewinde auf, über das das Gewindeelement 5 angetrieben ist. Das Gewindeelement 5 besitzt ein in die Gewindegänge des Rechts- bzw. Linksgewindes eingreifendes Führungselement, welches bei Erreichen eines jeden Endes des Gewindeabschnitts 4 den ineinander übergehenden Gewinden des Rechts- Linksgewindes folgt und so seine Bewegungsrichtung umkehrt. Der Zeiger 6 sitzt auf dem Gewindeelement 5 und wird entsprechend der Bewegung des Gewindeelements entlang der Skalenabschnitte hinund herbewegt. Das auf dem Gewindeelement 5 sichtbare Anzeigeelement 7 zeigt dabei die Bewegungsrichtung des Gewindeelements 5 an. Fig. 1 10 shows a plan view of a time display device according to the invention, in which the 24 hours of a day are divided into two time segments which are plotted along the scale section 1 in the one direction and the scale section 2 in the opposite direction. Parallel to and adjacent to the scale sections 1, 2 is a shaft 3, which is driven by a drive element 8, not shown. The threaded portion 4 of the shaft 3 has over its entire length both a right-hand and a left-hand thread through which the threaded element 5 is driven. The threaded element 5 has an engaging in the threads of the right-hand or left-hand thread guide element which follows upon reaching each end of the threaded portion 4 the merging threads of the right-left thread and thus reverses its direction of movement. The pointer 6 sits on the threaded member 5 and is reciprocated along the scale sections in accordance with the movement of the threaded member. The visible on the threaded member 5 display element 7 indicates the direction of movement of the threaded member 5.
