Definitions
- the invention relates to a watch with a watch case, the viewing opening of which is closed by a glass, with a bezel arranged rotatably drivably in the interior of the watch case, with a ring gear arranged on the bezel, into which a drive gear engages, which can be rotatably driven from the outside of the case is, the bezel can be driven rotatable by certain angular steps and can be fixed in a latching position by a latching device which resiliently latches after a completed angular step.
- a clock of the type mentioned is known.
- the actuating shaft can be axially displaced until it engages with a radially protruding driver attached to it in a corresponding recess in the drive gear, and a rotationally fixed connection is thus established.
- a large installation space is required due to the axial displacement of the control values.
- a watch with a continuously adjustable bezel is known from CH-A-17 13/62 and CH-A-499 147, which has a ring gear arranged on the bezel, into which a drive gear engages.
- the drive sprocket is non-rotatably arranged on an adjusting shaft which can be rotated manually.
- the object of the invention is to design clocks of the type mentioned in such a way that the bezel can be precisely positioned in the desired position in a simple manner.
- the manually rotatably drivable control shaft can be brought into operative connection with a drive pin rigidly connected to the drive gear, and the drive gear engages in the ring gear of the bezel, that the drive pin can be rotatably driven by the control shaft, drive pin and control shaft arranged coaxially to each other and freely rotatable relative to each other about their longitudinal axes by a certain angle, and wherein this drive pin on its cylindrical outer surface has a locking recess into which a radially resiliently loaded locking element can be locked.
- the exact position of the desired setting of the bezel is determined and held in a simple manner by the latching device. Since the adjusting shaft is only in operative connection with the drive pin for the adjustment process, but is otherwise effectively decoupled, any application of force to the locking device in the adjustment direction is avoided.
- the end of the drive pin facing the actuating shaft can have a rectangular cross section and a certain play is encompassed by the prongs of the fork-shaped end of the actuating shaft which extend axially to the longitudinal axis of the drive pin.
- the tines can have a circular sector-like cross section.
- the adjusting shaft For manual adjustment of the adjusting shaft, it can be rotatably mounted in a recess connecting the inside of the watch case to the outside of the watch case and can wear a crown at its end protruding from the watch case.
- a seal enclosing the recess can be arranged between the crown and the watch case, which can be an elastic sealing ring arranged between the watch case and the crown to ensure tightness.
- a particularly simple and at the same time securely positioned locking element is a locking ball.
- the latching element can be arranged movably in a radially extending guide fixed to the housing.
- the spring-loaded locking element tries always take the position that is the least distant from the longitudinal axis of the drive pin. This is exactly the center of the V-shaped recess. This ensures that the drive pin and thus the bezel are positioned exactly.
- a particularly exact positioning with securing in the set position is achieved in that the drive pin has a plurality of latching depressions distributed around the circumference, into which latching elements can be resiliently latched. Only a small amount of installation space is required if the locking recesses are arranged in a plane perpendicular to the longitudinal axis of the drive journal and distributed uniformly over the circumference.
- annular spring encloses all the latching elements in contact with the radially outer ends of the latching elements, only a single spring element is required to act on all the latching elements.
- the V-shaped locking recesses simultaneously form ramps for moving the locking elements radially outward, which have a pitch angle that ensures a non-blocking movement of the locking elements.
- the watch shown in the figures has a watch case 1 with a viewing opening 2, which is closed by a glass 3.
- An annular bezel 4 is rotatably mounted in the interior of the watch case 1. On its side facing away from the viewing opening 2, the bezel 4 is provided with a toothed ring 5, into which a radially directed one Longitudinal axis 6 rotatably drivable drive gear 7 engages.
- the drive gear 7 is non-rotatably connected to a drive pin 8 rotatable about the longitudinal axis 6.
- the free end 9 of the drive pin 8 directed towards the outside of the housing has a rectangular cross section, which is gripped with play by the prongs 10 of the fork-shaped end of an adjusting shaft 11 directed towards the inside of the watch case 1.
- the adjusting shaft 11 extends coaxially to the drive pin 8 through a recess 12 in the watch case 1 to the outside of the case and carries there a crown 13 which is screwed onto a thread 14 at the end of the adjusting shaft 11 protruding from the watch case 1.
- an outwardly projecting bearing sleeve 15 is inserted, in which the actuating shaft 11 is rotatably supported and axially secured.
- the crown 13 encompasses the outer end of the bearing sleeve 15 in a pot-like manner, an elastic sealing ring 16 being arranged under radial prestress between the part of the crown 13 encompassing the bearing sleeve 15 and the cylindrical outer surface of the bearing sleeve 15. As a result, the inside of the watch case 1 is sealed off from the outside.
- the tines 10 have a circular sector-like cross section, the extent of which is less than 180 °.
- the approximately diagonally opposite contact legs 17 of the tines 10 run parallel to each other with a distance that is slightly larger than that Width of the rectangular end 9 of the drive pin 8 is.
- a game between the tines 10 and the rectangular end 9 is achieved, which ensures free rotation by a certain angle of the drive pin 8 and the actuating shaft 11 relative to one another.
- the drive pin 8 is rotatably mounted in a bearing bore 18 of a positioning piece 19 arranged fixedly in the watch case 1.
- the drive pin 8 On its cylindrical outer surface, the drive pin 8 is provided with three latching depressions 20 distributed uniformly on the circumference on a plane perpendicular to the longitudinal axis 6.
- the locking recesses 20 have a V-shaped cross section and extend transversely to the longitudinal axis 6. This configuration means that the drive pin 8 has a cross section in the center of the locking recesses 20, which forms an isosceles triangle.
- three radially directed guides 21 are formed in the positioning piece 19, evenly distributed on the circumference, in each of which a locking ball 22 is guided so as to be radially movable.
- the positioning piece 19 is provided in the center of the guides 21 with a radially outwardly open, radially circumferential annular groove 23, in which an annular spring 24 is arranged, which surrounds the locking balls 22 and acts resiliently radially inwards. As a result, the locking balls 22 are pressed into the locking recesses located in their area.
- the various positions of an adjustment step are shown in FIGS. 3 to 7.
- FIG. 3 shows the basic position in which these two components are out of operative connection due to the play between drive pin 8 and actuating shaft 11. This can be seen in particular in FIG. 3b.
- the locking ball 22 is pressed by the ring spring 24 into its lowest possible position in the locking recesses 20. Since the drive pin 8 is freely rotatable by a certain amount, the locking balls 22 act on the locking recesses 20 so that the drive pin 8 and thus also the bezel 4 assume the exact position to be positioned.
- the actuating shaft 11 is moved by means of the crown 13 until the prongs 10 abut against the locating surfaces 25 of the end 9 of the drive pin 8 and this further rotated along. This is shown approximately in FIG. 4.
- the locking balls 22 are already moved radially outwards by a small amount through the walls of the locking recesses 20. This radial movement of the locking ball 22 to the outside is continued by further turning the crown 13 and the adjusting shaft 11 until the maximum position shown in FIG. 5 is reached, in which the locking balls 22 are on the border between two adjacent locking recesses.
- the locking balls 22 move into the locking recess (FIG. 6) adjacent to their original locking recess until they have largely assumed the lowest possible position in this new locking recess 20. If the crown 13 is no longer actuated, the locking balls press 22 now the drive pin 8 in the optimal position so that the bezel 4 is exactly in the new basic position.
Description
Die Erfindung bezieht sich auf eine Uhr mit einem Uhrgehäuse, dessen Sichtöffnung von einem Glas verschlossen ist, mit einer im Inneren des Uhrgehäuses drehbar antreibbar angeordneten Lünette, mit einem an der Lünette angeordneten Zahnkranz, in den ein Antriebszahnrad eingreift, das vom Gehäuseäußeren her drehbar antreibbar ist, wobei die Lünette um bestimmte Winkelschritte drehbar antreibbar und durch eine nach einem vollführten Winkelschritt federnd einrastende Rastvorrichtung in einer Rastposition fixierbar ist.The invention relates to a watch with a watch case, the viewing opening of which is closed by a glass, with a bezel arranged rotatably drivably in the interior of the watch case, with a ring gear arranged on the bezel, into which a drive gear engages, which can be rotatably driven from the outside of the case is, the bezel can be driven rotatable by certain angular steps and can be fixed in a latching position by a latching device which resiliently latches after a completed angular step.
Bei derartigen Uhren ist es schwierig bei einem Verstellen der Lünette die exakte neue Positiion der Lünette einzustellen. Diese Schwierigkeit ist besonders groß, wenn der Antriebszapfen mittels einer Dichtkrone verstellbar ist, da die dort vorhandenen elastischen Dichtringe sich nach einem Verstellvorgang zurückverformen und dadurch zu einem geringen Zurückverstellen der Lünette führen.With such watches, it is difficult to set the exact new position of the bezel when the bezel is adjusted. This difficulty is particularly great when the drive pin can be adjusted by means of a sealing crown, since the elastic sealing rings present there deform back after an adjustment process and thus lead to a slight adjustment of the bezel.
Insbesondere, wenn auf der Lünette in verschiedenen Positionen Städtenamen angeordnet sind, denen die Uhrzeit des dazugehörenden Landes zugeordnet ist, ist es wichtig in jeder Position die erforderliche Lage exakt einzunehmen.In particular, if city names to which the time of the associated country is assigned are arranged on the bezel in different positions, it is important to take the required position exactly in each position.
Aus der GB-A-11 25 790 ist eine Uhr der eingangs genannten Art bekannt. Zur Verstellung der Lünette ist die Stellwelle axial soweit verschiebbar, bis sie mit einem an ihr befestigten, radial hervorstehenden Mitnehmer in eine entsprechende Ausnehmung des Antriebszahnrades eingreift und so eine drehfest Verbindung hergestellt wird. Durch die axiale Verschiebbarkeit der Stellwerte wird ein großer Bauraum benötigt.From GB-
Aus der CH-A-17 13/62 sowie der CH-A-499 147 ist eine Uhr mit einer kontinuierlich verstellbaren Lünette bekannt, die einen an der Lünette angeordneten Zahnkranz besitzt, in den ein Antriebszahnrad eingreift. Der Antriebszahnkranz ist drehfest auf einer Stellwelle angeordnet, die manuell verdrehbar ist.A watch with a continuously adjustable bezel is known from CH-A-17 13/62 and CH-A-499 147, which has a ring gear arranged on the bezel, into which a drive gear engages. The drive sprocket is non-rotatably arranged on an adjusting shaft which can be rotated manually.
Aufgabe der Erfindung ist es, Uhren der eingangs genannten Art derart auszubilden, daß die Lünette auf einfache Weise in die gewünschte Lage exakt positionierbar ist.The object of the invention is to design clocks of the type mentioned in such a way that the bezel can be precisely positioned in the desired position in a simple manner.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die manuell drehbar antreibbare Stellwelle in Wirkverbindung mit einem mit dem Antriebszahnrad starr verbundenen Antriebszapfen bringbar ist, und das Antriebszahnrad in den Zahnkranz der Lünette eingreift, daß der Antriebszapfen durch die Stellewelle drehbar antreibbar ist, wobei Antriebszapfen und Stellewelle koaxial zueinander angeordnet und um einen bestimmten Winkel relativ zueinander frei um ihre Längsachsen drehbar sind, und wobei dieser Antriebszapfen an seiner zylindrischen Mantelfläche eine Rastvertiefung aufweist, in die ein radial federnd nach innen beaufschlagtes Rastelement einrastbar ist.This object is achieved in that the manually rotatably drivable control shaft can be brought into operative connection with a drive pin rigidly connected to the drive gear, and the drive gear engages in the ring gear of the bezel, that the drive pin can be rotatably driven by the control shaft, drive pin and control shaft arranged coaxially to each other and freely rotatable relative to each other about their longitudinal axes by a certain angle, and wherein this drive pin on its cylindrical outer surface has a locking recess into which a radially resiliently loaded locking element can be locked.
Durch diese Ausbildung wird auf einfache Weise durch die Rastvorrichtung die exakte Lage der gewünschten Einstellung der Lünette bestimmt und diese festgehalten. Da die Stellwelle nur zum Verstellvorgang mit dem Antriebszapfen in Wirkverbindung steht, sonst aber wirkentkoppelt ist, ist jede Kraftbeaufschlagung der Rastvorrichtung in Verstellrichtung vermieden.Through this design, the exact position of the desired setting of the bezel is determined and held in a simple manner by the latching device. Since the adjusting shaft is only in operative connection with the drive pin for the adjustment process, but is otherwise effectively decoupled, any application of force to the locking device in the adjustment direction is avoided.
Das der Stellwelle zugewandte Ende des Antriebszapfens kann einen rechteckigen Querschnitt aufweisen undd von den axial zur Längsachse des Antriebszapfens sich erstreckenden Zinken des gabelförmigen Endes der Stellwelle mit einem bestimmten Spiel umgriffen ist.The end of the drive pin facing the actuating shaft can have a rectangular cross section and a certain play is encompassed by the prongs of the fork-shaped end of the actuating shaft which extend axially to the longitudinal axis of the drive pin.
Dabei können die Zinken einen kreissektorartigen Querschnitt besitzen.The tines can have a circular sector-like cross section.
Zur manuellen Verstellung der Stellwelle kann diese in einer das Innere des Uhrgehäuses mit dem Gehäuseäußeren verbindenden Ausnehmung drehbar gelagert sein und an ihrer aus dem Uhrgehäuse herausragenden Ende eine Krone tragen. Dabei kann zwischen der Krone und dem Uhrgehäuse eine die Ausnehmung umschließende Dichtung angeordnet sein, die zur Sicherstellung der Dichtheit ein unter Vorspannung zwischen Uhrgehäuse und Krone angeordneter elastischer Dichtring sein kann.For manual adjustment of the adjusting shaft, it can be rotatably mounted in a recess connecting the inside of the watch case to the outside of the watch case and can wear a crown at its end protruding from the watch case. In this case, a seal enclosing the recess can be arranged between the crown and the watch case, which can be an elastic sealing ring arranged between the watch case and the crown to ensure tightness.
Ein besonders einfaches und zugleich sicher positionierendes Rastelement ist eine Rastkugel.A particularly simple and at the same time securely positioned locking element is a locking ball.
Damit das Rastelement im ausgerasteten Zustand sich auf einer genau definierten Bahn bewegt, kann das Rastelement in einer sich radial erstreckenden gehäusefesten Führung bewegbar angeordnet sein.So that the latching element moves in a disengaged state on a precisely defined path, the latching element can be arranged movably in a radially extending guide fixed to the housing.
Besitzt die Rastvertiefung einen sich quer zur Längsachse des Antriebszapfens erstreckenden V-förmigen Querschnitt, so versucht das federbelastete Rastelement immer die von der Längsachse des Antriebszapfens am geringsten entfernte Lage einzunehmen. Dies ist exakt die Mitte der V-förmigen Rastvertiefung. Somit erfolgt eine exakte Positionierung des Antriebszapfens und damit auch der Lünette.If the locking recess has a V-shaped cross section extending transversely to the longitudinal axis of the drive pin, the spring-loaded locking element tries always take the position that is the least distant from the longitudinal axis of the drive pin. This is exactly the center of the V-shaped recess. This ensures that the drive pin and thus the bezel are positioned exactly.
Eine besonders exakte Positionierung mit Sicherung in der eingestellten Lage wird dadurch erreicht, daß der Antriebszapfen mehrere am Umfang verteilt angeordnete Rastvertiefungen aufweist, in die Rastelemente federnd einrastbar sind. Dabei ist nur geringer Bauraum erforderlich, wenn die Rastvertiefungen in einer Ebene senkrecht zur Längsachse des Antriebszapfens gleichmäßig am Umfang verteilt angeordnet sind.A particularly exact positioning with securing in the set position is achieved in that the drive pin has a plurality of latching depressions distributed around the circumference, into which latching elements can be resiliently latched. Only a small amount of installation space is required if the locking recesses are arranged in a plane perpendicular to the longitudinal axis of the drive journal and distributed uniformly over the circumference.
Umschließt eine Ringfeder an den radial äußeren Enden der Rastelemente anliegend alle Rastelemente, so ist nur ein einziges Federelement zur Beaufschlagung aller Rastelemente erforderlich.If an annular spring encloses all the latching elements in contact with the radially outer ends of the latching elements, only a single spring element is required to act on all the latching elements.
Weist der Antriebszapfen drei Rastvertiefungen auf und bildet der Querschnitt des Antriebszapfens in der Mitte der Rastvertiefungen ein gleichschenkliges Dreieck, so bilden die V-förmigen Rastvertiefungen gleichzeitig Rampen zum Bewegen der Rastelemente radial nach außen, die einen ein blockierfreies Bewegen der Rastelemente gewährleistenden Steigungswinkel besitzen.If the drive pin has three locking recesses and the cross-section of the drive pin forms an isosceles triangle in the middle of the locking recesses, the V-shaped locking recesses simultaneously form ramps for moving the locking elements radially outward, which have a pitch angle that ensures a non-blocking movement of the locking elements.
Durch die Anzahl der Rastpositionen pro Umdrehung des Antriebszapfens und die Zähnezahlen des Antriebszahnrads und des Zahnkranzes der Lünette ist der Winkel eines Winkelschritts bestimmt.

Die in den Figuren dargestellte Uhr besitzt ein Uhrgehäuse 1 mit einer Sichtöffnung 2, die durch ein Glas 3 verschlossen ist.The watch shown in the figures has a watch case 1 with a viewing opening 2, which is closed by a
Im Inneren des Uhrgehäuses 1 ist eine ringförmige Lünette 4 drehbar gelagert. An ihrer der Sichtöffnung 2 abgewandten Seite ist die Lünette 4 mit einem Zahnkranz 5 versehen, in den ein um eine radial gerichtete Längsachse 6 drehbar antreibbares Antriebszahnrad 7 eingreift. Das Antriebszahnrad 7 ist drehfest mit einem um die Längsachse 6 drehbaren Antriebszapfen 8 verbunden.An annular bezel 4 is rotatably mounted in the interior of the watch case 1. On its side facing away from the viewing opening 2, the bezel 4 is provided with a
Das zum gehäuseäußeren gerichtete freie Ende 9 des Antriebszapfens 8 besitzt einen rechteckigen Querschnitt, der von den zum Inneren des Uhrgehäuses 1 gerichteten Zinken 10 des gabelförmigen Endes einer Stellwelle 11 mit Spiel umgriffen wird.The free end 9 of the
Die Stellwelle 11 erstreckt sich koaxial zum Antriebszapfen 8 durch eine Ausnehmung 12 im Uhrgehäuse 1 zum Gehäuseäußeren und trägt dort eine Krone 13, die auf ein Gewinde 14 am aus dem Uhrgehäuse 1 herausragenden Ende der Stellwelle 11 aufgeschraubt ist.The adjusting
In die Ausnehmung 12 ist eine nach außen hervorstehende Lagerhülse 15 eingesetzt, in der die Stellwelle 11 drehbar gelagert und axial gesichert ist. Das äußere Ende der Lagerhülse 15 wird von der Krone 13 topfartig umgriffen, wobei ein elastischer Dichtring 16 unter radialer Vorspannung zwischen dem die Lagerhülse 15 umgreifenden Teil der Krone 13 und der zylindrischen Mantelfläche der Lagerhülse 15 angeordnet ist. Dadurch ist das Innere des Uhrgehäuses 1 nach außen hin abgedichtet.In the
Wie insbesondere in den Figuren 3b bis 7b zu erkennen ist, besitzen die Zinken 10 einen kreissektorartigen Querschnitt, dessen Erstreckung weniger als 180° beträgt. Die sich dabei etwa diagonal gegenüberliegenden Anlageschenkel 17 der Zinken 10 verlaufen parallel mit einem Abstand zueinander, der etwas größer als die Breite des rechteckigen Endes 9 des Antriebszapfens 8 ist. Dadurch wird ein Spiel zwischen dem Zinken 10 und dem rechteckigen Ende 9 erreicht, das ein freies Verdrehen um einen bestimmten Winkel von Antriebszapfen 8 und Stellwelle 11 relativ zueinander gewährleistet.As can be seen in particular in FIGS. 3b to 7b, the
Der Antriebszapfen 8 ist in einer Lagerbohrung 18 eines fest im Uhrgehäuse 1 angeordneten Positionierstücks 19 drehbar gelagert. An seiner zylindrischen Mantelfläche ist der Antriebszapfen 8 mit drei auf einer Ebene senkrecht zur Längsachse 6 gleichmäßig am Umfang verteilten Rastvertiefungen 20 versehen. Die Rastvertiefungen 20 besitzen einen V-förmigen Querschnitt und erstrecken sich quer zur Längsachse 6. Durch diese Ausbildung besitzt der Antriebszapfen 8 in der Mitte der Rastvertiefungen 20 einen Querschnitt, der ein gleichschenkliges Dreieck bildet.The
In derselben Ebene wie die Rastvertiefungen 20 sind im Positionierstück 19 drei gleichmäßig am Umfang verteilte, radial gerichtete Führungen 21 ausgebildet, in denen jeweils eine Rastkugel 22 radial bewegbar geführt ist.In the same plane as the locking recesses 20, three radially directed
Das Positionierstück 19 ist mittig zu den Führungen 21 mit einer radial nach außen offenen, radial umlaufenden Ringnut 23 versehen, in der eine Ringfeder 24 angeordnet ist, die die Rastkugeln 22 umschließt und radial nach innen federnd beaufschlagt. Dadurch werden die Rastkugeln 22 in die jeweils in ihrem Bereich befindlichen Rastvertiefungen gedrückt.
In den Figuren 3 bis 7 sind die verschiedenen Positionen eines Verstellschrittes dargestellt.The
The various positions of an adjustment step are shown in FIGS. 3 to 7.
Figur 3 zeigt die Grundstellung, in der durch das Spiel zwischen Antriebszapfen 8 und Stellwelle 11 diese beiden Bauteile außer Wirkverbindung sind. Dies ist insbesondere in Figur 3b zu erkennen.FIG. 3 shows the basic position in which these two components are out of operative connection due to the play between
In dieser Stellung werden die Rastkugel 22 durch die Ringfeder 24 in ihre tiefstmögliche Lage in den Rastvertiefungen 20 gedrückt. Da dabei der Antriebszapfen 8 um ein bestimmtes Maß ungehindert frei drehbar ist, beaufschlagen die Rastkugeln 22 die Rastvertiefungen 20 so, daß der Antriebszapfen 8 und damit auch die Lünette 4 die exakte zu positionierende Stellung einnimmt. Zur Verstellung der Lünette 4 um einen Schritt, wobei eine Verstellung in gleicher Weise in beide Drehrichtungen erfolgen kann, wird mittels der Krone 13 die Stellwelle 11 bis zur Anlage der Zinken 10 an den Stellflächen 25 des Endes 9 des Antriebszapfens 8 bewegt und dieser im weiteren drehend mitgenommen. Dies ist etwa in Figur 4 dargestellt. Dabei werden durch die Wände der Rastvertiefungen 20 die Rastkugeln 22 bereits um ein geringes Maß radial nach außen bewegt. Diese radiale Bewegung der Rastkugel 22 nach außen wird durch weiteres Drehen der Krone 13 und der Stellwelle 11 fortgesetzt bis die in Figur 5 dargestellte Maximalstellung erreicht wird, in der die Rastkugeln 22 auf der Grenze zwischen zwei benachbarten Rastvertiefungen stehen.In this position, the locking
Bei weiterem Verdrehen der Krone 13 bewegen sich die Rastkugeln 22 in die zu ihrer ursprünglichen Rastvertiefung benachbarte Rastvertiefung (Figur 6) bis sie weitgehend die tiefstmögliche Lage in dieser neuen Rastvertiefung 20 eingenommen haben. Wird dabei die Krone 13 nicht mehr betätigt, drücken die Rastkugeln 22 nun den Antriebszapfen 8 in die optimale Position, so daß die Lünette 4 sich exakt in der neuen Grundstellung befindet.When the
