    The invention relates to the field of date display devices for mechanical watches, in particular in connection with annual calendars and in particular mechanical devices and modules for displaying the date itself.
    Date display devices for mechanical watches are generally modules, often called complications, which on the one hand have one or more mechanical interfaces with the movement and which on the other hand have a display unit.
    The mechanical date display devices used today differ from each other in both functionality and complexity. With regard to functionality, date display devices have been established which automatically take into account the number of days of the months with 30 or 31 days (annual calendar) or which even automatically take into account the month of February and leap years (perpetual calendar). Some date-display devices limit themselves to displaying the current day alone, while others - especially annual calendars and perpetual calendars - additionally display the month and / or year.
    In terms of complexity, the question arises as to how to diminish and simplify a date display module for given functionality, for example to make room for further modules or aesthetic adjustments, but also to simplify the manufacture of the clock and its reliability to increase. In answering this question, the concrete technical realization of the display unit itself is as important as the realization of the entire date display device.
    Various display units are in the field of mechanical watches in use. Roughly two different approaches can be distinguished. In a first approach, symbols for the day and optionally for the month are placed radially within the indices used for the time indication on the dial, such that all of these symbols are visible at all times. Each one coupled to the date display device and rotating pointer, often called date hand, then points to the current day and the current month.
    In a second approach, the symbols for the day and optionally the month are mounted on discs below the dial, the discs are coupled to the date display device and rotated by it. Through a recess in the dial, the current day and possibly the current day of the week can be read.
    Which of the two approaches is chosen for display units depends primarily on the desired appearance of the clock and the space requirements of other complications. The second approach leads to free space on the dial itself, but takes up a lot of space just below the dial. This complicates the incorporation of further complications. In the first approach, there is more freedom in positioning the various components of the display unit.
    For example, all may be mounted on a lower compared to the dial level, with only the drive axes of the pointers pierce the overlying levels and the dial. A disadvantage of this approach is that it leads to a more busy dial, which is less clear and leaves less room for other functionalities, such as a moon phase calendar or a chronograph leaves.
    There is a need to optimize the display unit of the date display in terms of space requirements both on the dial and in the case of the clock without disadvantages in the form of excessive complexity. The present invention therefore aims on the one hand to create space both in the housing of a mechanical watch and on the dial of the same and on the other hand to increase the clarity of the sizes indicated by the watch. Furthermore, the invention provides, inter alia, the possibility of driving the date displays radially out of the dial, whereby the largest possible date display can be combined with a concept which is not in the center of the clock, i. There, where most of the clocks the drive and the axes of rotation of the hour, minute and second hand sitting, takes up space.
    It is an object of the invention to provide an alternative display unit for a date display device, namely an annual calendar, of a mechanical watch.
    It is also an object of the invention to provide a display unit for a date display device, namely an annual calendar, a mechanical clock available, which impresses with its simplicity and therefore on the one hand connected with fewer steps with the other elements of the date display device , or can be integrated into the mechanical clock and on the other hand more space and room for maneuver with regard to further complications and aesthetic aspects, without resulting in a reduction in functionality or ease of use.
    These objects are achieved by the invention as defined in the claims.
    Mechanical watches, especially wristwatches and pocket watches, often have a substantially flat basic shape, in which the housing has a housing bottom and a central part, which has a circumferential wall, and a ring often called a bezel, which carries the watch glass , (the term "watch glass" here is not a limitation of the transparent material, which forms the protection of the dial). Through the bottom, middle part and watch glass (and optionally bezel) a substantially flat-disc-shaped interior is defined, which often has a circular, but possibly also different cross-section. Axial directions are directions perpendicular to the housing bottom, the radially-outer boundary of the interior is formed by the circumferential wall. The dial is located within the interior and is generally arranged substantially parallel to the housing bottom.
    An inventive embodiment of the display unit is installed as an integral part of a date display device, in particular a mechanical annual calendar, or as an independent submodule before installation in a mechanical clock. The watch has a dial, indexes, a case and a watch glass. The indices are arranged on the dial and serve in combination with a minute, hour and possibly second hand to indicate the time.
    The display unit itself has at least one display element of a first type and at least one display element of a second type and a display sprocket. A sprocket is here a particular internally toothed ring which can cooperate with a correspondingly arranged inside gear.
    The at least one display element of the first type is characterized in that it does not change its position relative to the dial, the case and the watch glass, for example by being mounted on one or incorporated in another way in the dial, case or watch glass is, for example by engraving, material application or in the form of one or more recesses or areas of different transparency.
    The at least one display element of the second kind is rotatably connected directly to the display sprocket or via a connection. For example, the at least one display element of the second type may be mounted on the display sprocket or a carrier which is connected via the said connection to the display sprocket, or be incorporated in another way, for example as previously mentioned, in the display sprocket or the carrier.
    The display sprocket can take a variety of angular positions, which are in relation to a day of the month. For example, the display sprocket 31 may occupy angular positions so that each angular position corresponds to a particular day of the month. In an alternative embodiment, the display sprocket 62 may occupy angular positions, allowing additional pre and afternoon discrimination. It is also possible for the display sprocket to assume further angular positions, which entails additional intermediate steps in the transition of the one-day-defining angular position to the angular position defining the next day.
    The non-rotatably connected to the display gear at least one display element of the second kind and relative to the dial, housing and watch glass of the clock a fixed position engaging at least one display element of the first type interact with each other in such a manner that an unambiguous indication of the current day of the month. In particular, a display unit according to the invention generally does not have a pointer attached to the axis of rotation of a toothed wheel and rotating with it for indicating the date. The display unit according to the invention then has no so-called date hand and dispenses in particular with a date hand, which is non-rotatably connected to the axis of rotation of a toothed wheel, for example a date wheel which lies radially within the indicator toothed ring.
    The date is given, for example, radially outside of the indices, which are mounted on the dial of the clock and which serve in combination with pointers to the time by either the at least one display element of the first kind and / or the at least one display element of the second kind radially outside the indexes is located.
    In one embodiment of the display unit are the indices, which are used in combination with pointers for timing, and the at least one display element of the first kind and / or the at least one display element of the second kind, which is radially outside the indices, or the web, on which the at least one display element of the second type moves, arranged concentrically to each other.
    In embodiments, the display elements of one type (the first type or the second type) form a set of date indices, in particular with the date numbers 1-31, the display element of the other type indicating one of these date numbers (ie one of the display elements) , thereby defining a location on the clock from which the date can be read. The display element of this other type may include, as further explained below, an arrow or line mark or mark with another symbol, a viewing window, a magnifying glass, a color marker or underlay, or the like.
    It can be provided in particular that the display elements which form the date indices, all remain visible at all times and change the date change only the relative position of the display elements of the first and second type. In particular, these embodiments exclude that a ring incorporating the date indices is located under the dial and is only partially visible through one or more apertures of the dial.
    The display elements of the first and second types are in many embodiments for the date display dedicated elements. That In these embodiments, none of the at least one display elements of the first and second types includes the indices used in combination with hour, minute and / or second hands for indicating time.
    In one embodiment, the display unit mounted on the dial indices are not radially-outside in the housing (ie immediately adjacent to the circumferential wall), but leave space for the at least one display element of the first kind or at least one display element of the second kind or the respective at least one display element of the first and second type. In this case, for example, all display elements belonging to the display unit are located in an area below the watch glass. In addition, the display elements belonging to the display elements are not on a belonging to the housing of the clock part.
    According to a first option, this can be realized by the at least one display element of the first kind is mounted radially outside the indices on the dial.
    According to a second option, all or individual of each at least one display element of the first and / or second type on a support, which in the case of at least one display element of the second type rotatably connected to the display gear, or mounted on the display sprocket, wherein Carrier and / or display sprocket, for example, are arranged radially outside the indices. Carrier and / or display sprocket need not lie on the same plane as the dial.
    In embodiments according to the second option, the entire dial extends in particular not flush to the radially encircling wall, but the display unit has at least one element which is rotatably connected to the display gear and between the example. From the middle part formed circumferential wall and the dial is located and turns; this element can surround the dial radially-outside. For example, this element may include one or more of the following components:the display sprocket itself or parts thereof;the at least one display element of the second kind or parts thereof;the carrier on which the at least one display element of the second type is mounted, or parts thereof, or a plurality of carriers or parts thereof; orthe connection between display sprocket and display element of the second kind or its carrier, or parts of this connection.
    Embodiments are also conceivable in which both the first and the second option are realized.
    In one embodiment of the display unit of the display sprocket is realized as inside gezähnter circular ring. The circular ring has an outer and an inner radius, wherein the outer radius is designed so that the circular ring is adjacent to the peripheral wall. The normal axes through the geometric centers of display sprocket and housing can coincide. Inner radius and thickness of the annulus are chosen so that the annulus has the necessary stability and reliability, but does not generate unnecessary space consumption.
    As is known per se, the watch, in which the date display device is installed with the display unit, further comprise a crown, with which a rotatable about an axis adjustment device is actuated.
    The crown can, as is also known per se, occupy at least two different positions spaced apart from the housing of the watch. In a first position, the angular position of the display sprocket is determined by a date wheel driven by the movement, and the date wheel drives the display sprocket. In a second position, the date wheel is decoupled from the movement, and the angular position can be determined by the user by turning the crown and thus the setting device, in a clockwise or counterclockwise direction, whereby the display gear and thus the at least one display element of the second kind with the inclusion Turn adjusting device also clockwise or counterclockwise.
    In one embodiment of the display unit, the adjustment or the drive of the display sprocket takes place both in the first and in the second position of the crown via a respective single element, which is coupled to the date wheel or the adjusting device. Of these two elements, only one is active at a time. The two elements are designed in particular as gears, which are referred to below as an intermediate (lying between date wheel and display gear) or Einstellzahnrad.
    Apart from these two interfaces of the display sprocket this has no further interfaces in the mentioned embodiment, which can drive the display sprocket.
    In a further embodiment of the display unit, the intermediate gear and the adjusting gear engage with the same via an inner toothing of the display gear rim designed as a circular ring. In addition, if the outer radius of the display sprocket chosen so that the display sprocket directly adjacent to the peripheral wall, this leads to an embodiment of the display unit, in which except for the crown and parts of the adjusting all elements that serve to drive and positioning of the display sprocket , are arranged within the display gear and act on it only from the inside.
    Furthermore, embodiments of the display unit differ in the relative arrangement of the at least one display element of the first type and of the at least one display element of the second type and the elaboration thereof.
    In a first category of embodiments of the display unit, the at least one display element of the first type has an indexing characterizing the days of the month. In particular, 31 display elements of the first type may be present, which are given by the numbers one to 31. These numbers are preferably arranged equidistant from each other on the dial radially outside the indices. The numbers can be applied to the dial or otherwise mounted on it, in this, for example by engraving, introduced or as numerical, going through the dial holes, be realized.
    In a second category of embodiments of the display unit, the at least one display element of the second type comprises the indexing characterizing the days of the month. In particular, 31 (or a multiple thereof) display elements of the second kind may be present, which are given by the numbers one to 31. These numbers are preferably equidistant from each other on the display sprocket or one or more other, with the display gear ring rotatably connected carrier, in particular a circular ring, mounted, applied or introduced. The latter can be done for example by engraving.
    In embodiments of the first and second categories, the highlighting of the current day is accomplished by having the display element of one type above the day of the month characterizing display elements of the other type. In particular, the display sprocket 31 (or a multiple thereof) may occupy angular positions, each of these angular positions resulting in the one display element, by its position, highlighting the display element characterizing the current day. The positioning is realized in such a way that the highlighting when viewing perpendicular to the dial is maximum, but also not vertical considerations lead to a clear identification of the day.
    In embodiments of both categories, the display element, which by its position emphasizes the display element characterizing the current day, can be realized in various ways. For example, it may be a magnifying glass, which magnifies the number located below the magnifying glass. However, it can also be a frame of any shape, which surrounds the number located below the frame in a preferably vertical viewing. But there are also other geometric shapes and symbols, such as arrows or triangles, conceivable, which point to the current day characterizing display element of the first kind.
    Also in embodiments of both categories, the display elements of a type may characterize the days of the month and be designed as the dial or a surrounding circular ring penetrating holes. The display element of the other type can then be arranged below these holes. The highlighting of the current day characterizing display element can then be done via a color sequence. For example, the emphasis may be realized by providing a well-perceived color matched to the overall appearance of the watch, just below the bore characterizing the current day.
    In embodiments of the first or second category, the at least one display element of the first type and the at least one display element of the second type are arranged radially offset, so that they do not overlap. In addition, the display elements may be on the same level, for example on the plane defined by the dial.
    In embodiments with radially offset display elements, for example, the at least one display element of the second kind has a geometric object and / or a symbol and / or another character, which is mounted on the display sprocket itself or on a rotatably connected thereto circular ring or introduced into this is. For example, the at least one display element of the second type may be an arrow or a triangle in which a tip indicates the display element of the first type characterizing the current day. The at least one display element of the second type can be located radially outside or radially inside the display elements of the first type. Even in the reverse configuration (the numbers are arranged on the display sprocket or a connected annulus and rotate while the geometric object / symbol is fixed to the housing) that is conceivable.
    Further embodiments of the display unit may have one or more of the following features:Display sprocket and dial are not concentric;Not all display elements that characterize the days of the month are visible or equally visible at all times. This can be realized, for example, in that the at least one display element of the type which does not characterize the days of the month contains transparent, semi-transparent and / or non-transparent regions.The dial, may have further recesses which allow the view of the mechanics of the clock, the date display device and / or the display unit while allowing a mechanical connection of components of the display unit.
    In accordance with the invention, the display unit may be part of a clock, which preferably has a date display device tuned to the display unit and a dial, a minute hand and an hour hand, indices, a housing and a watch glass. In this case, the display unit is the component characterizing the clock.
    A date display device adapted to the display device is shown in unpublished Swiss Patent Application No. 00 638/15 by the same Applicant. The content of this Swiss Patent Application is hereby incorporated into the description of the present invention.

    Hereinafter, the operation and implementation of the invention will be shown with reference to various exemplary embodiments. It should be understood that the invention is not limited to these embodiments, but includes other embodiments consistent with the claims.
    Fig. 1 shows an external view of a clock 100, which has an embodiment of the display unit. In addition to this display unit, the clock has a housing 14, a dial 12 with indices 23 mounted thereon, an hour 103, minute 102 and month hand 104, a moon phase display 101, and a crown 20.
    The display unit of the first type 21 is in the embodiment shown as a symbol, namely an arrow formed, which is located on the periphery of the dial 12 at the three-clock position.
    In the embodiment shown, the dial does not extend to the housing, but leaves room for the display elements of the second type 22. These have the numbers 1 to 31 and are arranged on a circular ring 24. The annulus is located on the same plane as the dial 12 and surrounds it radially, being arranged between the dial and the housing. Thus, the display elements of the second kind are radially peripherally arranged compared to the indices 23 for minute and hour indication.
    The annulus on which the display elements of the second type are arranged, may be a correspondingly shaped display sprocket or a circular ring which is fixedly connected to the display sprocket.
    In the embodiment of the display unit shown in FIG. 2, it is the display elements of the first type 21 which have the numbers 1 to 31. Further, the dial 12 extends to the housing 14, and the display elements of the first kind are arranged on the dial at its periphery, in particular outside the indices 23. The numbers 1 to 31 are realized as the dial penetrating recesses.
    The display element of the second type 22 consists of a color sequence which is applied below the dial on the display sprocket itself or on a fixedly connected circular ring or other carrier. In the embodiment shown, the color sequence is selected such that only the recess characterizing the current day differs in color from the other recesses. In addition, the color sequence can be chosen so that the color impression of the current day characterizing recess changes throughout the day. Alternatively or additionally, the color sequence can also extend over a plurality of recesses, whereby the current day can still be ascertained beyond doubt. Ultimately, the chosen color sequence can be adjusted to the appearance of the clock as a whole.
    Also in the embodiment of the display unit shown in Fig. 3, the display elements of the first type 21, the numbers 1 to 31, which are arranged on the periphery of the dial 12, in particular outside the indices 23. The display element of the second type 22 is mounted above the dial 12. The coupling of the display element of the second type with the display sprocket is done via a gap which is located between dial and housing 14 and a running connection. The display element of the second type is formed in the embodiment shown as a magnifying glass, which increases the current day characterizing mark.
    Fig. 4 shows a schematic representation of a section of the embodiment of the display unit according to FIG. 3 along the axis designated AA in FIG. 3. Only the elements essential to this embodiment are shown. The display element of the second type 22 (here a magnifying glass) is mounted on a support 17, which in turn is rotatably connected via a connection 16 with the display sprocket 1. The connection runs in a gap 18, which is formed between dial 12 and housing 14 of the clock. The display element of the first type 21 is located on the dial and is highlighted by the display element of the second type 22. For better orientation, the passage 19 for the axes of rotation of the hour and minute hands is also shown in Fig. 4.
    Fig. 5 is another schematic illustration of a section through an embodiment of the display unit. In this embodiment, it is now a part of the display sprocket 1 itself or one with the same rotatably connected circular ring which projects into the gap 18 between dial 12 and housing 14 of the clock. Such an embodiment is an example of a design with radially offset display elements of the first and second type.
    Fig. 6 shows the structure and operation of a display unit coupled to a date display device. The date display device and display unit shown lead to a particularly simple assembly, since the display unit has only two designed as gears interfaces to the date display device. One of the two gears, called Zwischenrad 2, ensures that the display sprocket is driven by the date display device. The other of the two gears, called Einstellzahnrad 11, serves to advance and reset the date displayed by the user.
    In the embodiment of the display unit shown in Fig. 6, the display sprocket 1 is designed as an internally toothed circular ring, which is arranged and dimensioned so that all of the essential elements listed below the date display device, but also the clock itself and other complications radially can be arranged within the display gear.
    The illustrated date display device for realizing an annual calendar has the following essential components:A coupling rocker 7, which has a coupling pin 7.1, a roller 7.2 and a decoupling pin 7.5;A drive wheel 8, with which a driving device is rotatably connected, wherein the driving device has a driving head 8.1 and a rotational axis 8.3. In the embodiment shown, the axis of rotation 8.3 of the entrainment device coincides with the axis of rotation 7.4 of the drive wheel and both axes of rotation are mounted on the coupling rocker 7. Furthermore, the drive wheel has an interface 15 to the movement.A date wheel 4, which has a month wheel driving pin 4.1 and a track 4.2. The track also has a recess 4.3;A month wheel 5, with which a monthly cam 6 is rotatably connected. The monthly cam has twelve segments with the same opening angle, each segment standing for one month and the segment of a month having 31 days having a larger radius than the segment of a month having 30 days;A transfer date gear 3 and an idler gear 2 via which the display unit couples to the date wheel with only the idler gear in contact with the display sprocket; such asA decoupling rocker 9, which interacts on the one hand via a deflecting element 10 with the crown (not shown) of the clock and on the other hand is in contact with the decoupling rocker 7.
    The exact mode of operation of the annual calendar shown is described in the unpublished Swiss Patent Application No. 00 638/15 by the same Applicant. The content of this patent application is hereby incorporated by reference. The most important aspects are briefly reproduced below.
    The driving device can occupy three different positions relative to the date wheel 4. In a first position, the driver head 8.1 pulls the date wheel one interaction per interaction. In a second position, the driver head pulls the date wheel by two units per interaction. In a third position, an interaction between driving device and date wheel is not possible. If the date wheel is realized with 31 teeth, one unit equals one day.
    The position occupied by the driving device depends on the state of the coupling rocker 7. This condition is determined by the coupling pin 7.1, which scans the monthly cam 6, the roller 7.2, which runs along the track 4.2, and by the decoupling pin 7.5, which is in contact with the decoupling rocker 9 and thus with the crown of the clock.
    As long as the user does not pull the crown of the clock radially outwards, the date display device is in normal operation. In this, a first state of the coupling rocker 7 is determined by the position of the roller 7.2, which runs along the track 4.2 along. This first state of the coupling rocker does not change during the first to 29th day of a month and corresponds to the first position of the driving device.
    On the 30th day of the month, the roller 7.2 runs into the recess 4.3, unless this is prevented by the resting of the coupling pin 7.1 on a one month with 31 days coding segment of the monthly cam 6. If the run-in of the roller prevented in the recess, the coupling rocker 7 remains in the first state and the driving device in the first position. If, however, the roller runs into the recess, the coupling rocker assumes a second state and the driving device changes into its second position, which is also characterized in that the relative distance between the driving device and the date wheel 4 has decreased compared to the first position. In this second position, the driving head 8.1 pulls the date wheel by two units (days) and the date wheel changes from the position characterizing the 30th day of the month directly to the position characterizing the first day of a month.
    On the first day of the month, the date wheel has turned so far that the roller 7.2 can no longer run into the recess 4.3. The coupling rocker 7 is again in the first state and the driving device is in its first position.
    Regardless of the day of the month and regardless of whether the driving device is in the first or second position determined in normal operation, only the date wheel 4, the angular position of the display sprocket 1. In the embodiment shown date wheel and display sprocket interact solely and solely on the idler 2, ie Drive and positioning of the display gear is done at any time via one and the same element.
    The user now has the option to switch by radial withdrawal of the crown control of the display sprocket 1 from the date wheel 4 on the setting gear 11 connected to the setting device. This is shown in Figs. 7 and 8.
    Fig. 7 shows again the switching essential components of the date display device and the display unit in normal operation. These are: the display sprocket 1, the date wheel 4, the coupling rocker 7, the decoupling pin 7.5, the driver head 8.1, the decoupling rocker 9, the axis of rotation 9.7 of the decoupling rocker 9, the deflecting element 10 and the adjusting device 13, with which the crown (not shown ) tensile and rotationally fixed and the Einstellzahnrad 11 are rotatably connected.
    Fig. 8 schematically illustrates the steps leading to said switching. By pulling out the crown or the setting device 13 (step i), the decoupling rocker 9 is rotated about its axis of rotation 9.7 (steps ii and iii), which in turn pushes the coupling rocker 7 in its third state (step iv), which is characterized in that the relative distance between date wheel 4 and driving device 8.1 increases so much that no interaction between the driving device and the date wheel is possible any more. Thus, the date wheel and thus the display sprocket 1 is no longer driven by the movement. At the same time, the adjusting gear 11 (see FIG. 6) rotatably connected to the adjusting device 13 couples to the display sprocket, whereby the user can easily advance and reset the date indicated by the display unit by turning the crown (step v).
