Abstract

The present display assembly is suitable for a watch having its face in an approximately vertical position, and comprises a combination of hands (10), turning at different speeds, and a dial ring (1), the time-keeping drive shaft (7) bearing the two display means. The dial ring (1) in this case hangs with its inner circumference (11) in the groove (17) of a roller (2) connected to the drive shaft (7) and takes over the rotary movement from the said roller by the two interacting circumferential surfaces rolling against each other. Errors which may occur during the transference of the turning moment are compensated by a correcting device. <IMAGE>

Description

Die Erfindung betrifft eine Anzeigevorrichtung für eine Uhr mit etwa vertikaler Zifferblattlage, die aus einer Kombination von, mit verschiedenen Ge­schwindigkeiten drehenden Zeiger und Zahlenreif be­steht, wobei eine zeithaltende Antriebswelle beide Anzeigemittel trägt, mit der Aufgabe, die relativ beschränkten Möglichkeiten der Ausgestaltung analog anzeigender Uhren zu erweitern.The invention relates to a display device for a watch with an approximately vertical dial position, which consists of a combination of rotating at different speeds hands and number ring, with a timed drive shaft carries both display means, with the task of the relatively limited possibilities of designing analog display clocks expand.

Bei Uhren mit analoger Zeitanzeige kreisen üblicher­weise zwei verschieden lange Zeiger vor einem, mit Stunden- und Minuteneinteilung versehenen Ziffer­blatt. Die beiden Zeiger sind konzentrisch im Mittel­punkt des Zifferblattes gelagert und machen durch ihre Stellung ein Zeitmessergebnis sichtbar. Es sind auch Lösungen mit nur einem Zeiger für ein bestimmtes Zeitmaß, oder mit einem dritten Zeiger, der zentral oder seitlich angeordnet sein kann und meist die Sekunde anzeigt, üblich.
Andere umlaufende Anzeigemittel sind Scheiben, die an­stelle der Zeiger montiert sind und zylindrische, kugelförmige oder ähnlich geformte Körper, die sich um ihre Achse drehen. Sie besitzen meist eine Zeit­skala, wobei der aktuelle Wert in einem Fenster er­scheint oder durch einen feststehenden Zeiger markiert wird.In watches with an analog time display, two hands of different lengths usually circle in front of a dial with hour and minute division. The two hands are positioned concentrically in the center of the dial and their position makes a timekeeping result visible. Solutions with only one pointer for a certain amount of time or with a third pointer, which can be arranged centrally or laterally and usually indicate the second, are also common.
Other revolving display means are disks which are mounted instead of the pointers and cylindrical, spherical or similarly shaped bodies which rotate about their axis. They usually have a time scale, whereby the current value appears in a window or is marked by a fixed pointer.

Aus der CH-PS 8161 ist eine Zeitanzeigeeinrichtung bekannt geworden, bei der ein Zeiger die Minuten- und ein ruckartig drehender Zahlenreif die Stunden­werte angibt. Auch die US-PS 1,453,087 beschreibt eine solche Anzeigevorrichtung.From CH-PS 8161 a time display device has become known, in which a hand indicates the minutes and a jerky number ring indicates the hour values. US Pat. No. 1,453,087 also describes such a display device.

Bei beiden Ausführungen ist der Zahlenreif drehbar mit der Werkplatte verbunden und eine Anzahl von Rädern, Hebeln und Federn, die funktionell zwischen der zeigertragenden Antriebswelle und dem Zahlenreif liegen, sorgen für seine Weiterschaltung und Arre­tierung. Die Anordnung des Zahlenreifens ist damit nur unter der Zifferblattebene möglich.In both versions, the number ring is rotatably connected to the work plate and a number of wheels, levers and springs, which are functionally located between the pointer-carrying drive shaft and the number ring, ensure that it is indexed and locked. The arrangement of the number tire is therefore only possible under the dial level.

Die vorliegende Erfinung bezweckt, der kombinierten Anzeigeform mit Zeiger (10, 14) und Zahlenreif (1) als drehende Anzeigemittel, ein neues Erscheinungs­bild zu geben und technisch wesentlich zu verein­fachen.The present invention aims to give the combined display form with pointer (10, 14) and number ring (1) as rotating display means a new appearance and to simplify it technically substantially.

Dieses Ziel wird dadurch erreicht, daß der Zahlen­reif (1) weitgehend von den technischen Einrichtungen, welche nach den bisher bekannten Lösungen an mehreren Stellen seines Umfanges vorhanden sind und die der Lagerung, Weiterschaltung und Arretierung dienen, befreit wird.This goal is achieved in that the number range (1) is largely freed from the technical devices, which according to the previously known solutions exist at several points of its scope and which are used for storage, forwarding and locking.

Erfindungsgemäß hängt der Zahlenreif (1) lediglich mit seinem Innenumfang (11) auf dem zu einer Rolle (2) mit axialer Nut (17) aus gebildeten Teil der zeit­haltenden Antriebswelle (7), wobei die Berührungs­stelle mit dem Nutboden (18) Stützpunkt (Lagerung) des Zahlenreifens (1) ist, und gleichzeitig auch der Drehmomentsübertragung dient.According to the invention, the number ring (1) only hangs with its inner circumference (11) on the part of the time-keeping drive shaft (7) formed from a roller (2) with an axial groove (17), the point of contact with the groove bottom (18) supporting point (storage ) of Number tire (1), and also serves to transmit torque.

Der Zahlenreif (1) liegt mit seinem Innenumfang (11) am Nutboden (18) der Rolle (2) auf und übernimmt die Drehbewegung durch Abrollen der Umfangflächen. Die vorzugsweise im rechten Winkel zum Nutboden (18) stehende Rollenwände (3,4) dienen der Führung des Zahlenreifens (1) und ergeben zusammen mit einem Hindernis (5), das sich am Zahlenreif (1) befindet, die Korrektureinrichtung, welche Fehler bei der Be­wegungsübertragung (Schlupf) ausgleicht.The number ring (1) lies with its inner circumference (11) on the groove bottom (18) of the roller (2) and takes over the rotary movement by rolling off the circumferential surfaces. The roller walls (3, 4), which are preferably at right angles to the groove bottom (18), serve to guide the number tire (1) and, together with an obstacle (5) located on the number ring (1), result in the correction device, which errors occur compensates for the transmission of motion (slip).

Die Korrektureinrichtung wird zumindest einmal pro Umdrehung des Zahlenreifens (1) wirksam und besteht vorzugsweise aus einem Stift (5), der auf beiden Seiten des Zahlenreifens herausragt und den beiden die Rollennut (17) flankierenden Rollenwände (3,4), wobei diese je eine etwa v-förmige Ausnehmung (15) besitzen. Da der Bewegungskreis, den das Hindernis (5) beschreibt, den Kreisumfang (19) der Rolle (2) schneidet, kann das Hindernis (5) die Rolle (2) nur mit Hilfe der Ausnehmungen (15) in den beiden Rollen­wänden (3,4) passieren.The correction device takes effect at least once per revolution of the number tire (1) and preferably consists of a pin (5) which protrudes on both sides of the number tire and the two roller walls (3, 4) flanking the roller groove (17), each one have approximately V-shaped recess (15). Since the movement circle described by the obstacle (5) intersects the circumference (19) of the roller (2), the obstacle (5) can only roll (2) with the help of the recesses (15) in the two roller walls (3, 4) happen.

Eilt der Zahlenreif (1) seiner bestimmten Stellung voraus, trifft das Hindernis (5) auf den Rollenum­fang (19) und wird bis zum Eintreffen der Ausnehmungen (15) angehalten (Fig. 5). Ist der Zahlenreifen (1) seiner korrekten Stellungen gegenüber zurück, trifft das Hindernis (5) auf die Ausgangsflanken (16) der Aus­nehmungen (15). In der Folge wird der Zahlenreifen (1) angehoben und durch Abgleiten des Hindernisses (5) an den Ausnehmungsflanken (16) nach vorne ver­schoben (Fig. 6).If the number ring (1) hurries ahead of its particular position, the obstacle (5) hits the roller circumference (19) and is stopped until the recesses (15) arrive (FIG. 5). If the number tire (1) is back from its correct positions, the obstacle (5) hits the exit flanks (16) of the recesses (15). As a result, the number tire (1) is raised and the obstacle (5) slides on the recess flanks (16) moved forward (Fig. 6).

Die Korrektureinrichtung ist auch wirksam, wenn das Hindernis (5) nur auf einer Seite aus den Zahlen­reifen (1) herausragt und nur die mit ihm zusammen­treffende Rollenwand (3 oder 4), die v-förmige Aus­nehmung (15) besitzt.The correction device is also effective if the obstacle (5) only protrudes from the number tire (1) on one side and only the roller wall (3 or 4) that meets it and has the V-shaped recess (15).

Der Zahlenreif (1) kann, wie in Figur 1 und 2 darge­stellt, vor dem Zifferblatt (12) oder wie bekannt auch unter diesem angeordnet werden. Bei Verwendung vor dem Zifferblatt (12) wird ein feststehender Be­zugspunkt (6) die Stundenwerte ablesbar machen. Mit Hilfe mehrerer entsprechend angeordneter, fest­stehender Zeiger, können verschiedene Zonenzeiten dargestellt werden.As shown in FIGS. 1 and 2, the number ring (1) can be arranged in front of the dial (12) or, as is known, underneath it. When used in front of the dial (12), a fixed reference point (6) will make the hourly values readable. With the help of several appropriately arranged, fixed hands, different zone times can be displayed.
