Abstract

The invention relates to an analogue watch which is designed to display the time in at least two different time zones and which comprises a clockwork, a handwork driven by the clockwork with at least one hour hand and one minute hand, and a dial on which the hands of the handwork the time in a first time zone is displayed, with a rotatable dial disc being arranged behind the dial, on which the hour values of at least one second time zone are arranged in a circle, and the dial having at least one recess through which an hour value of the at least one second time zone can be seen at any time is readable.

Description

The invention relates to a watch which, in addition to the time in the time zone of the watch wearer, also displays the time in at least one other time zone.

An analog watch uses hands on a dial to tell the time. Pointers are usually rod-shaped, rotatably fastened to a pointer shaft protruding through a hole in the dial and arranged over a display side of the dial, so that the pointers sweep over a (partial) circular surface of the dial.

The hand train is an assembly of a mechanical clock and consists of the parts minute wheel, quarter tube (this carries the minute hand), change wheel and hour wheel (this carries the hour hand).

The hand train transmits the drive to the minute wheel spindle. The minute wheel, the change wheel and the hour wheel with change drive translate the respective pointer speed. The speed of rotation of the minute wheel is reduced via a change wheel and a change gear to the hour pipe, which only turns at 1/12 revolutions per hour.

There is an overall gear ratio of 1:12 or 1:24 between the quarter tube and the hour wheel, depending on a 12-hour or 24-hour scale. The hour hand is fixed on the hour tube and the minute hand on the quarter tube. The quarter tube is connected to the minute wheel shaft or the minute tube via a slipping clutch. The slipping clutch allows the time to be set after pulling the crown.

The hands of the watch are moved by a movement that draws its energy from a spiral spring or a battery. The spring is wound either by hand or by the movement of the self-winding watch. Analog clocks can display other data besides the time, e.g. B. day, date, year, or moon phases.

The display of the time for a second time zone is one of the most popular complications on high-quality mechanical wristwatches. In the course of the technical implementation, several different solutions have been developed for the instruments, which are often also referred to as GMT watches.

Watches that display two or more time zones on a dial are already known. For this purpose, either several movements are housed in one case (e.g. Glashütte Original Senator Cosmopolite), or an additional mechanism enables the display of several time zones.

In order to be able to display a second time zone, watches require - depending on the model - an additional hand and a 24-hour scale, an additional small auxiliary dial or an adjustable ring with indication of the different time zones. The latter is typically in the form of city names, which are the reference locations of the individual time zones.

1. 1. Ein zentral angeordneter zusätzlicher Stundenzeiger zeigt die Zeit einer zweiten Zeitzone an. Der Abstand des zusätzlichen Stundenzeigers zum Haupt-Stundenzeiger ist einstellbar und der zusätzliche Stundenzeiger wird mit gleichbleibendem Abstand zum Haupt-Stundenzeiger mitgeschleppt.
2. 2. Ein zentral angeordneter zusätzlicher Stundenzeiger zeigt die Zeit einer zweiten Zeitzone an. Der zusätzliche Stundenzeiger läuft mit halber Geschwindigkeit und zeigt die Zeit der zweiten Zeitzone auf einer separaten 24-Stunden-Skala an, die entweder auf dem Zifferblatt oder einer Lünette angebracht ist.
3. 3. Auf dem Zifferblatt ist ein kleines Hilfszifferblatt angeordnet, auf dem ein zusätzlicher Stundenzeiger sowie in manchen Fällen ein zusätzlicher Minutenzeiger die Zeit der zweiten Zeitzone anzeigen.

The following three additional mechanisms are most commonly used:

1. 1. A centrally located additional hour hand shows the time in a second time zone. The distance between the additional hour hand and the main hour hand is adjustable and the additional hour hand is dragged along at a constant distance from the main hour hand.
2. 2. A centrally located additional hour hand shows the time in a second time zone. The additional hour hand runs at half speed and displays the time in the second time zone on a separate 24-hour scale mounted either on the dial or on a bezel.
3. 3. A small sub-dial is placed on the dial, on which an additional hour hand and, in some cases, an additional minute hand indicate the time of the second time zone.

From the DE 40 30 744 A1 a clock is known which displays half-hourly time zones. The CH 684 916 B5 discloses a watch with a crown that can be pulled out in three stages. The DE 873 522 C shows a watch with a locking device for stopping a display when setting. The U.S. 5,054,008 discloses a timepiece having a face with a south pole projection. The DE 691 17 142 T2 shows a watch with a face depicting a map of the world developed 360° with Antarctica at the center. From the DE 200 13 105 U1 a watch is known which has a time zone disc with place names as a dial. The U.S. 2,268,239 shows a clock with a scale divided into sections of 15° each. Finally shows the U.S. 197,246 a watch with a dial with the South Pole in the center and the North Pole on the edge.

Clocks are known for displaying the respective times at different locations on earth, in which a great many, mostly 24, city names are arranged on a ring. The time in these Cities are indicated by a 24-hour ring that rotates once a day, rotating relative to the former ring.

The object of the invention is to create a structurally simple clock for displaying the time of at least one second time zone, based on an existing clockwork, or to add the functionality of a time zone display to an already existing clockwork.

According to the invention, the above object is achieved with the features of claim 1. Advantageous refinements and developments are described in the dependent claims.

A first aspect of the invention relates to a novel and particularly advantageous way in which the time of one or more second time zones can be displayed on an analogue clock that is known per se.

For this purpose, an analogue watch is proposed which is designed to display the time in at least two different time zones and which comprises a clockwork, a handwork driven by the clockwork with at least one hour hand and one minute hand, and a dial face on which the time of a first time zone is displayed by means of the hands of the hand train, with a rotatable dial disc being arranged behind the dial face on which the hour values of at least one second time zone are arranged in a circle, and the dial face having at least one cut-out through which an hour value of the at least one second time zone can be read at any time is.

In other words, unlike known GMT watches, the time of an additional time zone is no longer indicated by additional hands or rings. Instead, a dial disc with printed hour values is arranged behind the dial, one of which can be seen through the recess. The minute value can be read from the minute hand of the first time zone. The recess can be inscribed on the dial with the name of the displayed time zone or the name of a metropolis located in this time zone, for example.

The invention makes it possible to display the times of one but also several other time zones in addition to the first time zone in a new and unique way. With the solution according to the invention it is possible to display the times of a large number of time zones simultaneously and very intuitively in a particularly attractive manner.

For this purpose, according to a first embodiment of the proposed analog watch, it can be provided that the dial has several, preferably up to seven, cutouts, the cutouts being at different distances from the center of the dial and the hour values of a number of different time zones corresponding to the number of cutouts being arranged in a circle on the dial disc, but with different diameters.

There are no limits to the arrangement of the one or more recesses on the dial. As a result, special attention is paid to the alignment of the hour values of the one or more second time zones arranged on the dial disk. If a recess is not on the horizontal or vertical axis of the dial, this results in a complex alignment for each individual hour value so that each individual hour value is displayed in the correct orientation and can be read.

An optically particularly appealing, attractive design of the proposed watch can be achieved by arranging a section of a world map on the dial and arranging the at least one recess at a location on the world map that corresponds to the location of a metropolis. There are no limits to the selection of the section and in almost every case several sections can be positioned in such a way that several second time zones can be displayed in parallel.

In the proposed clock, the display of the first time zone is completely analog with hour hand, minute hand and, if applicable, second hand, whereas the display of the one or more second time zones is half analog (regarding the minutes) and half digital, i.e. with discrete numerical values (regarding the hours). Therefore, in a further embodiment, it is provided that the dial disk is moved forward by one hour value every full hour. This ensures that the hourly value of every second time zone is always fully visible in the respective recess and only changes to the next hourly value once, namely on the hour.

In order to implement an hourly switching of the hour values of the one or more second time zones, provision can be made, for example, for the dial disc to be mounted on a ratchet wheel which is held in one of 24 positions by a ratchet spring in 15-degree increments and which is moved by an adjusting disc by a 15-degree increment to the next position every full hour.

A second aspect of the invention relates to the implementation of an additional time zone display using an intrinsically complete caliber.

To this end, it is proposed to connect the dial firmly and the dial disc rotatably to a module plate to form a time zone module, and to attach the time zone module to the front of a caliber, with the caliber driving the time zone module being connected to the time zone module and the pointer shafts of the caliber protruding through the time zone module. In this way, the functionality of displaying one or more additional time zones can be retrofitted to existing calibers at any time. All that has to be ensured is a mechanical coupling of the time zone module with the caliber.

According to a further embodiment, it can be provided that the ratchet wheel and the detent spring are part of the time zone module and the adjusting disk is part of the caliber and performs a full revolution every hour, with part of the revolution jumping every full hour.

A third aspect of the invention relates to the possibility of adapting the display of the first time zone to the actual location of the user, for example when traveling, without affecting the display of the other time zones, the time of which does not change as a result.

In addition, it is proposed that the pointers of the pointer train and the dial disc can be adjusted together via a winding stem of the movement, and the hour hand of the pointer train can also be quickly and independently adjusted via a setting stem in order to adapt the display of the first time zone to the location of the user of the watch.

For this purpose, it can be provided, for example, that the setting shaft can be brought into one of three angular positions by turning it, with the axial mobility of the setting shaft being blocked in a first angular position, in a second angular position, axial pressure on the setting shaft causes the hour hand to be adjusted forwards by one hour, and in a third angular position, axial pressure on the setting shaft causes the hour hand to be adjusted backwards by one hour.

According to one embodiment, it is provided for this purpose that the actuating shaft has a detent plate with three detent recesses and a detent plate spring snaps into one of the three detent recesses in each of the three angular positions.

According to a further embodiment, it can be provided that the setting shaft has a setting lever which, in the second and third angular position, acts on one lever arm each when axial pressure is applied to the setting shaft, and the two lever arms cause the hour hand to move by one hour in each direction of rotation in 30-degree increments when axial pressure is applied to the setting shaft.

According to another embodiment, it can be provided that an hour ratchet wheel is arranged on the hour wheel, which is moved by the hour wheel during normal operation and which can be rotated in 30-degree increments relative to the hour wheel against the force of an hour ratchet spring.

In a further embodiment, it can be provided that the two lever arms each act in one direction of rotation on a corrector disc, which is thereby brought into engagement with the hour wheel and the hour wheel is rotated relative to the hour wheel by a 30-degree step.

In 1 1 is an overall view of the movement of the proposed watch according to an embodiment. You can see the winding stem 29 at the 3 o'clock position and the setting stem 1 at the 10 o'clock position. In the center of the dial 23 are the hour tube and the minute tube as well as the seconds wheel for the analogue display of the time in a first time zone.

The dial 23 is only shown here in a reduced representation, without indices, and the hands of the analog display are also not present. It can be seen that the dial 23 has six recesses 28 which are arranged at different distances from the center of the dial 23 . In each recess 28 another hour value can be seen as a number. The recesses 28 are labeled on the dial 23 with the names of various metropolises that are in the time zones whose hour value can be read in the respective recess 28 . In the exemplary embodiment, these are Brisbane, Tokyo, Dubai, Reykjavik, Buenos Aires, Phoenix and Honolulu.

• Auf einer Schablone 30 (linke obere Darstellung) sind in sieben konzentrischen Kreisen jeweils 24 Stundenwertpositionen markiert, die gleichzeitig mögliche Positionen für Aussparungen 28 des Zifferblatts 23 kennzeichnen. Während für jede kreisförmige Anordnung dieser Stundenwertpositionen die Auswahl nur einer einzigen für die Position einer Aussparung 28 des Zifferblatts 23 sinnvoll ist, muss auf der hinter dem Zifferblatt 23 angeordneten Zifferblattscheibe 25 (mittlere obere Darstellung) jede kreisförmige Anordnung von Stundenwerten, für die tatsächlich eine Aussparung 28 im Zifferblatt 23 vorgesehen ist, mit aufgedruckten Stundenwerten voll besetzt sein.

In 2 the interaction of the basic elements of the time zone display is shown:

• On a template 30 (upper left illustration), 24 hour value positions are marked in seven concentric circles, which at the same time indicate possible positions for recesses 28 of the dial 23 . While for each circular arrangement of these hour value positions it makes sense to select only one for the position of a recess 28 of the dial 23, each circular arrangement of hour values for which a recess 28 is actually provided in the dial 23 must be fully occupied with imprinted hour values on the dial disk 25 arranged behind the dial 23 (middle upper representation).

Since in the embodiment of 1 In fact, since there are seven slots 28, each belonging to one of the seven circular arrangements, then on the dial 25 all hour value positions of all seven circles must be fully occupied. It should be noted here that the inclination of the printed hour values depends on the specific position of the recess 28 through which the hour values of the respective circular arrangement are to be able to be read.

In this specific case, the positions of the recesses 28 are chosen so that the 1 visible designations of the recesses 28 correspond to the position of the respective metropolis in the selected section of the world map 31, which is shown in the upper right representation.

If you now add the three interacting basic elements of the time zone display, i.e. the selection of the positions of the recesses 28 on the dial 23 according to the template 30, the dial disk 25 with the hour values, the inclination of which is adapted to the position of the respective recess 28, and the selected section of the world map 31, the result is an analogue watch which, in addition to the analogue display for a first time zone, enables a simultaneous, analogue-digital hybrid display for seven further time zones. The way these time displays are presented is of high aesthetic value and absolutely unique in this form.

3 uses a total of 15 examples to show the unrivaled variety of design options, which, by focusing on different parts of the world, enable all markets worldwide to be served in a way that no other GMT concept can offer.

In the exemplary embodiment, the functionality of the time zone display is implemented in a separate time zone module, which is placed on a caliber and mechanically connected to it in such a way that the caliber drives the time zone module. 4 shows a section through the time zone module.

On the module plate 26, a base 24 and at the edge a dial support 27 are attached in the middle. The dial 23 rests on these two elements and is fastened to three threaded pillars which are fastened to the module plate 26 by means of three screws through three through-holes in the base 24 . The base 24 encloses a bearing bushing 22 which carries the ratchet wheel 19 to which the dial disk 25 which is arranged between the dial 23 and the module plate 26 is screwed.

The complete mechanics of the quick adjustment of the hour hand and the switching of the dial disc is in 5 in a plan view, i.e. from the dial side, in 6 in a first perspective view, also from the dial side, and in 7 shown in a second perspective view from the rear.

The dial disk 25 fills the entire area behind the dial 23 and is attached to the ratchet wheel 19 which is mounted centrally on the module plate 26 by means of the bearing bushing 22 . The locking wheel 19 is held by the locking spring 7 in one of 24 possible positions, which can be fine-tuned via the eccentric locking spring 9 and the player 11 .

The drive of the ratchet wheel 19 and thus of the dial disk 25 causes the desired jumping switching of the time zone display. For this purpose, an adjusting disc 12 is driven by the caliber, which completes a full revolution every hour. The adjusting disk 12 has an outer contour whose distance from the center of rotation increases continuously, so that this outer contour deflects a roller 14 , which is located at the free end of a shift lever 15 pivoted on one side, against the increasing force of a shift spring 16 .

At the end of a full revolution, i.e. on the hour, the outer contour of the adjusting disc 12 abruptly allows the shift lever with the roller 14 attached to it to be moved back towards the adjusting disc 12 by the switching spring 16, whereby the adjusting disc 12 is given a rotary impulse, through which a nose of the adjusting disc 12 engaging in the outer toothing of the locking wheel 19 suddenly rotates the locking wheel 19 further. This rotation is limited by the fact that the detent spring 7, which also engages in the outer teeth of the detent wheel 19, jumps one tooth further, as a result of which the detent wheel 19 is not moved by more than a 15-degree increment to the next position and the next hour value is displayed in the recess or recesses.

The switching of the dial disc 25 takes place every hour in jumping form when the centrally seated minute hand passes the 12 and triggers the system of the switching spring 16 in cooperation with the adjusting disc 12.

The adjusting disc 12 is continuously in the power flow with the drive. Due to its translation, it rotates once an hour. On the outer contour of the adjusting disk 12, when the adjusting disk 12 rotates, the roller 14, which is attached to the free end of the shift lever 15 articulated on one side, is moved outward together with the shift lever 15, i.e. away from the axis of rotation of the adjusting disk 12. As a result, the switch spring 16, which is in contact with the switch lever 15 on the underside of this, is tensioned further and further, which is crucial for the switching of the dial disk 25. The switching spring 16 mounted below the shift lever 15 becomes more and more tense as the adjusting disc 12 rotates and presses the shift lever, including the roller 14, more and more against the outer contour of the adjusting disc 12.

Shortly before the centrally running minute hand passes 12, the roller 14 resting on the outer contour of the setting disk 12 together with the shift lever 15 is furthest away from the axis of rotation of the setting disk 12 and the switching spring 16 is fully tensioned. As the minute hand passes 12, the roller 14 with the shift lever 15 finally falls over the step in the outer contour of the setting disk 12 and causes the setting disk 12 to flip forward (clockwise). Thus, an engagement with the ratchet wheel 19 comes about, which is finally switched on by one position.

Below the adjusting disc 12 there is a toothed driver (not shown), which engages in the change wheel and finally establishes the connection to the drive. The driver contains a pin that ultimately limits the freedom of movement of the adjusting disk 12 . After the switching of the dial disk 25, the adjusting disk 12 is caught up again by the driver after a few minutes and the process starts again from the beginning. Since the disk is very large and also relatively heavy, a detent spring 7 has been integrated. This engages in the ratchet wheel 19 and prevents the dial disc 25 from skipping several hours at once due to inertia.

Also mounted centrally is the hour wheel 10 with the hour wheel 8 arranged on it, which is held in place by an hour detent spring 17 during normal operation, so that it moves identically to the hour wheel 10 . For quick adjustment of the hour hand, the force of the hour detent spring 17 can be overcome by a quick adjustment mechanism, and the hour detent wheel 8 can thereby be adjusted relative to the hour wheel 10 .

In the exemplary embodiment, this quick-adjustment mechanism includes the control shaft 1, which can be rotated and displaced axially. The control shaft 1 has a locking plate 2 with three locking depressions. By twisting the control shaft 1 can be brought into one of three angular positions. In each of the three angular positions, a detent plate spring 21 snaps into one of the three detent recesses. In the middle of the three angular positions, an axial movement of the control shaft 1 is prevented by the fact that the detent plate hits a stop inside the housing. When the control shaft 1 is rotated in one of the two possible directions of rotation, the control shaft 1 moves into one of the other two angular positions. In each of these two angular positions, the adjusting lever 4 arranged on the adjusting shaft 1 is aligned in such a way that it acts on either a first lever 5 or a second lever 20 when there is axial pressure on the adjusting shaft 1 .

The two levers 5 and 20 in turn act on the corrector disc 6, which has teeth facing the hour ratchet wheel 8. The corrector disc 6 is brought into engagement with the hour wheel by the action of one of the two levers 5 or 20 against the force of a corrector spring 18 and the hour wheel 8 is rotated relative to the hour wheel 10 by the action of the corrector disc 6, which ultimately results in the quick adjustment of the hour hand. Depending on which of the two levers 5 or 20 acts on the corrector disk 6, the hour hand is adjusted either forwards or backwards by one hour.

Power is transmitted from the setting shaft 1 and the setting shaft drive 3 via a lever arm system 5, 20 to the corrector disc 6, which is aligned towards the center. The corrector disc 6 has the same toothing as the hour wheel (number of teeth and module are identical). Regardless of the main time and the dial disc 25, the system advances the hour hand one position, ie, one full hour, each time the crown is pressed. The hour detent spring 17 riveted to the hour detent wheel 8 ensures independent switching. Its spring force was designed in such a way that it first clicks one position further before overcoming the actual movement force. The hour wheel 10 running underneath thus remains in the previous position and unaffected.

The switching takes place in jumping form. The process is possible in both directions (forwards and backwards) and is identical.

There are a total of 3 crown positions in which the crown or the setting shaft 1 is arrested by the interaction of the detent plate spring 21 with the detent plate 2 of the setting shaft 1 . The pusher cannot be operated in the middle position, as a stop has been provided in the movement. This position serves as a zero position in normal operation or everyday life.

Depending on the position of the crown, the forces from the lever arm 5 or 20 act on the rear surfaces of the corrector disc 6, which finally tilts through a slot into the hour ratchet wheel 8 and allows it to click one position further forward or back. The corrector disk 6 and the affected lever arm 5, 20 are then moved back to their starting position due to the spring forces acting on them, before the hour hand can finally be corrected by another hour (pressing once corresponds to one hour).

Operation of the clock in normal operation

In principle, the setting of the hands and the dial disk 25 takes place as usual via the winding stem. The hour hand is then corrected using the newly developed, convenient push-button function.

Should the operator fly from New York to Berlin, all he has to do is press the pusher on the stem 1 and thereby correct the hour hand depending on the time difference.

In order not to mess up the whole system and to adjust the time zones of the metropolises shown, which have not changed, the crown at 10 o'clock is used for a comfortable quick adjustment.

The operator couples the crown into the correct position and then uses the newly developed pusher function. Each time the crown is pressed (in this example coupled to the "forward" position), the hour hand alone jumps forward by a full hour, regardless of the main time and the time zones displayed. Due to the quick-adjustment circuit, which is independent of the movement, the dial disc 25 and the minute hand remain in their position. The hours shown in the respective recesses of the dial 23 are still correct.

If the operator returns to his starting point A, he repeats the process, clutching the crown at 10 o'clock to the "return" position.

full winding of the watch

The watch lies in the cupboard over the weekend and comes to a standstill after the power reserve has expired. Accordingly, neither the local time nor that of the metropolises AA, BB, CC, etc. is displayed correctly.

The operator winds the watch as usual using the crown of the winding stem and then does not set the local time, but that of a freely chosen city shown in one of the recesses of the dial 23, such as that of Metropole CC.

Adjustment is possible both forwards and backwards. The dial disk 25 moves forwards jumping, backwards continuously. With each full revolution of the minute hand, the dial disc 25 advances one position. One position corresponds to one full hour in each of the seven slots.

Finally, the operator corrects the central hour hand at the 10 o'clock position by means of the quick adjustment by means of the setting shaft. All time displays are now correct.
