Definitions
- the invention relates to the field of date display devices for mechanical watches, and more particularly to an annual calendar.
- JP 2651 150 shows an annual calendar in which a mechanism causes only a wheel carrying the date display to be advanced by two units at the end of a short month.
- a dedicated drive wheel which carries a driver is arranged stationary.
- US 2,886,910 shows a calendar mechanism in which a lever at the end of each month reads via a pin the information coded by a wheel, whether the month in question is long or short. A firmly screwed on a gear with a predetermined axis of rotation driver actuates the calendar mechanism.
- CH 705901 shows different annual calendars. At the end of a short month, a driver in some implementations causes a date-bearing wheel to shift directly from the 30th to the 1st day at the end of a short month.
- the date display device comprises a drive wheel which is coupled to the movement of the mechanical clock. About this coupling, the device is driven and thus also a time signal introduced into the device. Connected to the drive wheel and driven by this is a device which in turn at regular intervals with a date wheel and this drives. This device is referred to below as a "driving device.” Furthermore, the device has a month wheel, which interacts directly or via intermediate wheels with the date wheel and which occupies an angular position representing the month of the year.
- the coupling of the drive wheel to the movement is particularly fixed in the sense that a movement of the movement at any time causes a corresponding movement of the drive wheel - in particular, the drive wheel is coupled via a gear connection to the clockwork.
- the angular position of the date wheel - which may be a date gear - is characteristic of the Dalum, which can be used directly or indirectly, via an element coupled to the date wheel, for date display.
- the entrainment device has a unit which is referred to as a "driver”, which directly comes into contact with the date wheel, for example, as well as an axis of rotation about which the driver rotates but not mandatory, designed as a circular path.
- a driver which directly comes into contact with the date wheel, for example, as well as an axis of rotation about which the driver rotates but not mandatory, designed as a circular path.
- the driver may also interact indirectly, for example via idler gears and / or pins, with the date wheel.
- the driving device may occupy at least two positions, which differ in their relative position to the date wheel, or to the axis of rotation of the date wheel, and as a consequence thereof by the angle by which the driving device rotates the date wheel per interaction. If the driving device rotates the date wheel by one unit per interaction in a first position, it rotates the date wheel by a plurality of units per interaction in a second position. The device is arranged to bring the entrainment device from the first to the second position or not at a predetermined angular position of the date wheel (corresponding to the end of the month, especially the 30th of the month) depending on a state of the month wheel.
- the fact that the entrainment device can assume two positions relative to the date wheel means that the entrainment device as a whole can assume two positions relative to the date wheel, that is to say in particular to the date wheel Rotary axis of the entrainment device - ie the two positions differ in particular not only by different rotational positions of the driving devices ..
- To the month wheel can be coupled a - possibly also with this one-piece - monthly cam which encodes the length of the month and depending on their angular position allows movement to the second position or not.
- Date display devices of the presently claimed kind are often considered to be examples of so-called complications. In the present case, however, this is not intended to be a statement about the complexity of the device; Rather, the inventive approach allows a particularly simple and, if necessary, a particularly well integrated into the movement construction.
- one and the same mechanism be used for advancing the date wheel by one day on a regular date change as well as for propelling the date wheel by more than one day at the end of a shorter month ,
- the difference between the propulsion for one or more days is thus not caused by various mechanisms as known from the prior art and not by differently wide drive paths (eg., Different large rotations) of the driving mechanism, but by setting a relative position of the driving Mechanism (driving device) and the date wheel.
- This allows a significantly simplified compared to the prior art design with only a few necessary for the annual calendar function additional elements and almost no additional space.
- the relative movement between the first and the second position is, for example, a movement of the driving device relative to the other parts of the device, the date wheel is then fixed in its position.
- the reverse movement of the date wheel in, for example, fixed path of the driving device is not excluded.
- the first of the two positions corresponds to the normal position, which is always taken with the exception of the end of the month.
- the second position is taken in short months at the end of the month, so that the date wheel in its movement in the interaction with the driving device skips a day.
- the positions of the entrainment device and the date wheel can be determined both in their horizontal, i. differ in a plane parallel to the plane of the date wheel, as well as vertical layers.
- the axis of rotation of the driving device may be closer to the axis of rotation of the date wheel than in the first position.
- the different relative positions can also be realized differently, for example by different positions perpendicular to the plane.
- the date wheel has means for in each position of the driving device with the driver in a position-dependent Way to interact.
- a change in the angle by which the date wheel rotates per interaction with the driving device can be realized, for example, by the fact that the overlap between the path on which the teeth of the date wheel move and the path of the driver increases accordingly.
- the rotation of the date wheel for example, realized in that the driver hooks with the teeth of the date wheel and this entrains before decouple driver and date wheel due to their different paths again.
- the rotational axis of the follower When the rotational axis of the follower is closer to the rotational axis of the date device in the second position, it engages in advance and engages with the date wheel for a longer distance than in the first position.
- the driver can be mounted radially resiliently.
- the driver is designed as a driver head or driving pin. This can move on a circular path around its axis of rotation.
- Driver and rotation axis are as mentioned preferably connected so that the driver is mounted radially resiliently to its path. Furthermore, this connection is, for example, designed so that the driver tangentially to the web is rigidly connected directly or indirectly to the drive wheel. This can for example be realized in that the driver is held on a resilient, approximately circumferential arm. In one embodiment, the connection between the driver and its axis of rotation can be configured spirally.
- the driving device may further comprise optional stops which define a maximum radial and / or tangential deflection of the driver. These can be designed so that they define different positions, which can take the driver. Alternatively or additionally, these can also protect against excessive mechanical impact, which could cause damage to the driving device.
- the axis of rotation of the driving device is identical to that of the drive wheel driving the driving device. In this case - and quite generally as an option - the axis of the drive wheel, for example, not fixed but between different positions - in particular according to the positions of the driving device movable.
- the entrainment device can be designed so that the driver interacts once per complete revolution of the drive wheel with the date wheel.
- the driving device can be firmly connected to the drive wheel, for example by the axes of rotation of drive wheel and driving device are rotatably coupled.
- the driver can be directly, i. without intervening elements, contact the date wheel.
- the shape of the teeth of the date wheel and the shape of the driver are coordinated so that they fit into each other. Furthermore, these can be designed so that occurring, small angular position errors are automatically corrected.
- the fault tolerance is further increased by a radially resilient, tangentially rigid mounting of the driver.
- An embodiment for realizing at least two different positions of the driving device relative to the date wheel additionally has a coupling rocker on which the axis of rotation of the driving device is seated.
- the axis of rotation of the driving device does not coincide with that of the coupling rocker.
- the at least two positions of the driving device are given by at least two states of the coupling rocker, which differ in the orientation of the coupling rocker.
- the coupling rocker can have a spring blade as well as one or more coupling parts, for example in the form of a coupling pin, a roller, an abutment surface, etc.
- the spring leaf presses the coupling part (s) in a certain direction against one or more components of the device or the clock. This makes it possible that the state of the coupling rocker is dependent on the position, orientation and / or the state of other components.
- the date wheel or a separate element coupled to it may have, for example, a track mounted above or below the toothing, which has a recess in that angular position of the date wheel which identifies the 30th day of the month. If the one coupling part - for example, a coupling part designed as a roller - is pressed into the recess, the coupling rocker changes to the second position.
- the spring leaf also presses a second coupling part present on the coupling rocker, for example a pin against the monthly cam and at the same time the first coupling part against the running track.
- a second coupling part for example a pin against the monthly cam and at the same time the first coupling part against the running track.
- the first coupling part for example a roller
- the second coupling part for example a pen
- the coupling rocker it becomes possible for the coupling rocker to shift to a second state in which the driving device is at the second position if the first coupling part identifies the 30th day of the month and at the same time identifies the second coupling part a month with only 30 days.
- a monthly cam of the type mentioned can be arranged above or below the month wheel, wherein the axis of rotation of the monthly cam is identical to that of the month wheel and is rotatably connected thereto.
- Monthly cam and month wheel can also be made from one piece.
- angular positions for the date wheel 31 which are defined by 31 equidistant spaced teeth.
- the driving device in a first position relative to the date wheel, rotates the date wheel per day and interacts around a tooth.
- propulsion is two teeth in an interaction.
- the driving device in a second position relative to the date wheel, propulsion is two teeth in an interaction.
- the driving device in the second position, the driving device will be closer to the date wheel and the driver will engage a tooth located further forward with respect to the direction of rotation.
- the date wheel may also have n * 31 teeth, where n is an integer. If the driver changes once a day rotates its own axis and once interacts with the date wheel, the Mildgingvorrichlung in the first position turns the Dalumsrad by 360 / (31 * n) degrees and by 2 * 360 / (31 * n) degrees, when the driving device in a second Position is located.
- the date wheel interacts directly, i. without intermediate gears, with the month wheel.
- the month wheel and the date wheel have means that allow a wheel of the month wheel initiated by the date wheel.
- the date wheel may have a month wheel driving pin arranged to rotate, independently or in combination with other month wheel driving pins, the month wheel to the angular position characteristic of the beginning month after one month has elapsed.
- the month wheel driving devices can in particular directly access the teeth of the month wheel.
- the month wheel 12 may assume defined angular positions, which are defined, for example, by 12 equidistant spaced teeth.
- the date wheel rotates once a month on its own axis, an interaction between date wheel and month wheel on the last day of each month is sufficient, so that the month wheel, which occupies correct Winkclposition for the beginning of the month.
- the device has means which enable a visual reading preferably of the complete date consisting of the current day of the month, the day of the week and the current month, but at least the current day of the month by the user via the dial of the clock.
- the date wheel 31 and the month wheel 12 can assume defined angular positions, this can be done by means of visualization, which are directly coupled to the corresponding gear.
- a corresponding day wheel which can take seven defined angular positions and interacts once a day with the drive wheel or date wheel, can be realized in a manner known per se.
- the device can have lever springs which engage with the various gears, in particular with the date wheel and / or the month wheel, when they assume a predetermined, defined angular position.
- the accuracy of the angular position occupied by the various gears can be increased and at the same time a locking thereof can be ensured.
- the latter increases the reliability of the clock against external disturbances, for example due to bumps.
- the device comprises a device with which the Dalum can be easily moved back and forth by the user.
- the axis of rotation of the entrainment device can assume a further position, referred to below as "third", relative to the date wheel, in which the mimetic device does not interact with the date wheel third position is initiated by the user by actuation (for example, pulling out) of an outside mounted on the watch case crown.
- the driving device is in this third position, the date can be adjusted via the crown attached to the housing, for example by turning the crown. It is possible to set the date back and forth.
- Embodiments of this group may be based on the above-described coupling rocker, the outside crown attached to the housing and a gear which is coupled to the crown and begins to interact directly or indirectly with the date wheel as soon as the crown is switched to the third position of the driving device was initiated.
- the coupling between this gear and the crown is designed so that the date in a simple manner, e.g. by turning the crown, can be adjusted.
- the coupling rocker has at least one decoupling part, for example in the form of a decoupling pin.
- This serves to translate the housing of the clock relative position of the crown in an orientation of the coupling rocker. For example. Pulling out the crown is implemented via the decoupling section so that the axis of rotation of the driving device assumes the third position. In this third position, the path of the driver does not overlap with that of the teeth of the date wheel. Consequently, date wheel, month wheel and all other elements of the device, which lead to a visualized on the dial date, decoupled from the drive wheel and thus the movement itself.
- the device may further comprise a decoupling rocker with at least two defined states.
- the Entkoppunswippe which in turn a spring leaf, a rotation axis and elements can be defined, with which different states of the decoupling rocker can be defined and which allow switching between the various states.
- the decoupling rocker interacts directly or indirectly with the crown and the coupling rocker, or the decoupling part, and ensures that a change in the relative position of the mounted outside the housing crown to a corresponding change in the orientation of the coupling rocker and thus the position of the axis of rotation of the driving device leads.
- the gear which can be switched on and then interacts with the crown and the date wheel, can not be arranged on such a decoupling rocker on its axis of rotation.
- the driving device can take other positions in addition to the discussed first, second and possibly third position.
- the embodiment just described for the positioning of the driving device is in fact a mechanical implementation of the principle of classical AND logic. This is the case because each button queries a relevant date for the information and allows its rigid connection with the coupling rocker switching the rocker, if the queried date state arrives. However, the rocker only switches to another position if all the relevant queries of the date state for this position provide a corresponding result. Based on this, extensions of the annual calendar according to the invention, for example in the direction of an eternal calendar, are conceivable.
- a mechanical watch is also part of the invention. Such has, in addition to the date display device on a clockwork and a time display with at least two pointers and a dial, which can all be configured in a manner known per se.
- FIG. 2 Structure of an embodiment of the annual calendar
- Figures 3a-3c An embodiment for date correction by the user
- FIG. 5 shows an exemplary embodiment of the date wheel
- Month cam; and Figure 7 An exemplary embodiment of a coupling rocker.
- FIGS. 1 a and 1 b show an outer (FIG. 1 a) and an inner view (FIG. 1 b) of a mechanical clock 100 with a year calendar, in which the day of the month and the month itself are displayed in addition to the clock.
- a watch has the following elements: a dial 12, on which are mounted devices (for example indices) which, in combination with hands or other visualization methods, enable the reading of the time, the day of the month and the month.
- the watch shown also has an adjusting device 13 and a complication not essential to the invention for displaying the moon phase (moon phase clock 101 ) with an associated pointer 106.
- the adjusting device may be terminated at its out-of-the-clock end by a crown (not shown), the crown being, for example, fixedly connected to the writing insert.
- the mechanism of the annual calendar includes, inter alia, the following in Fig. Lb well recognizable elements on: intermediate 2, transfer date gear 3, month wheel 5, axis of rotation 7.4 of the drive wheel 8, which in the embodiment shown with the axis of rotation 8.3 of the driver 8.1 is identical, a Gear 15 for coupling the annual calendar to the mechanical clock and its axis of rotation 7.8. Furthermore, in the interior view for better orientation, the pointers for reading Minutes 102, hours 103, month 104 and moon phase 106 added. The watch itself is completed by a housing 14.
- FIG. 2 shows the components required for the realization of the annual calendar and their interaction.
- the annual calendar is driven by the drive gear 8 connected to the movement via the gear 15.
- the axis of rotation 7.4 of the drive wheel is mounted on a coupling rocker 7 and designed so that the drive wheel once a day completely, i. by 360 ° to the given by the position of the coupling rocker rotation axis 7.4 rotates.
- the rotational axis 8.3 of the driver head 8.1 coincides with the axis of rotation 7.4 of the drive wheel 8 together, these two axes of rotation are rotatably connected to each other. As a result, the driver head also turns 8.1 once per day completely around its axis 8.3.
- the driver head 8.1 is designed to interact once a day with a date wheel 4.
- the date wheel 4 is formed as a gear with 31 equidistantly arranged on a given radius teeth.
- the date wheel also has a track 4.2 and a month wheel driving pin 4.1. 5 shows a detailed view of an exposed date wheel 4.
- a fixing opening 4.4 the center of which with the axis of rotation of the Date wheel coincides.
- the track 4.2 is designed as a circular disc having a semi-circular recess 4.3 at one point radially outward.
- the date wheel 4 in turn is on the month wheel driving pin 4.1 in interaction with a month wheel 5.
- the month wheel 5 has twelve equidistantly arranged on a given radius prongs. it is firmly connected to the month wheel is a monthly cam 6.
- Figure 6 shows a detailed view of an exposed month wheel with monthly cam.
- the month wheel driving pin 4.1 is arranged on the date wheel 4, that this hooked once per complete revolution of the date wheel 4 with a spike of the month wheel and this moves by its further progression on its circular path by one position. This ensures that the month wheel, after twelve full revolutions of the date wheel, is once complete, i. rotated 360 ° around its axis.
- Reference symbol S.sub.1 designates a pixel aperture 5.1 which centrally scans the monthly cam, the center of which coincides with the rotational axes of the month wheel and the monthly cam.
- Lever springs 16 ensure that the gears take only well-defined angular positions and that they remain in these angular positions until the next interaction with another element of the device or the watch takes place. Furthermore, the levers prevent external influences from causing malfunctions.
- the coupling rocker 7 and thus the axes of rotation 7.4 / 8.3 of the drive wheel 8 relationship, the driver head 8.1 occupy two positions.
- the coupling rocker 7 is Y-shaped, with the three ends of the coupling rocker elements given by the Y-shape interacting with other components of the annual calendar.
- FIG. 7 shows a detailed view of an exposed coupling rocker.
- the head end 7.6 of the coupling rocker has a roller 7.2 and a coupling pin 7.1.
- the coupling pin 7.1 scans the monthly cam 6, which is divided into twelve segments. These segments are arranged so that they are in clear relation to the given by the gears of the month wheel 5 positions of the months by the month cam 6 rotatably connected to the month wheel 5. Furthermore, the segments differ in their radii by having one of two possible radii. The larger of the two Radii encodes one month with 31 days, while the smaller of the two Radii stands for one month with 30 days.
- the coupling rocker 7 is pressed in the direction of the date wheel 4 due to a spring force generated by a spring blade 7.3, so that the roller rolls on the track 7.2 4.2 7.2. At each end of the month, the roller 7.2 reaches a recess 4.3, whereby the track can not prevent a movement of the coupling rocker to Datersad out.
- the coupling pin 7.1 lies in the region of a segment which has the smaller of the two radii, then the coupling pin can not prevent a change in position of the coupling rocker 7 as soon as the roller comes into the region of the recess 4.3 of the track 4.2.
- the coupling rocker rotates about its axis of rotation 7.8, and the axes of rotation 7.4 / 8.3 of the drive wheel or the driver head move in the direction of the dalum wheel 4. The latter causes the overlap of the web on which moves the driver head and the web on which the 31 teeth of the date wheel are arranged, enlarged.
- FIG. 7 also shows a fixing opening 7.8 and a further coupling pin 7.9.
- the axis of the fixing aperture coincides with the axis of rotation of the coupling rocker and with that of e.g. shown in Figure 2 gear 15, which accomplishes the coupling of the annual calendar with the clockwork.
- the recess 4.3 and the roller 7.2 are designed by this mechanism so that the driver head at the end of the 30th day of a month, which is identified by the monthly cam 6 as a month with 30 days, the date wheel by two units with it. After this one day, the roller leaves the recess 4.3 again, whereby the driver head again assumes the retracted position relative to the date wheel. As a result, the driving head pulls in its subsequent interaction with the date wheel this again only by one position with it.
- the driving head is mounted radially resiliently.
- this is realized in that the connection between the driver head 8.1 and the axis of rotation 8.4 of the driver head is designed to be elastically deformable. This allows the driver head to temporarily shift its position in the direction of its axis of rotation should a correspondingly directed force be exerted on the driver head by the date wheel.
- the driver head can be configured such that a change in the orientation of the driver head caused by the position of its axis of rotation relative to the teeth of the date wheel can not lead to jamming.
- Another advantage of a radially resilient mounting of the driver head is that by appropriate design of the resilient mounting of the driver head between the teeth of the date wheel is pressed. As a result, relative position errors between date wheel and driving device, both in terms of the relative position of their axes of rotation and the angular positions of the date wheel and driving head, be corrected.
- FIGS. 4a-4f the mechanism just described and underlying the device is illustrated step by step.
- the length of the month is coded by a segmentation of the cam 6.
- a larger radius segment corresponds to one month to 31 days and a smaller radius segment to one month to 30 days. If the larger radius is labeled H and the smaller radius is L, the monthly cam will display the following radii sequence for the months of January through December: HLHLHLHHLHLH.
- Figure 4a shows the starting position on the 29th day of a month with 30 days.
- the roller 7.2 is still in front of the recess 4.3, whereby a switching of the coupling rocker is prevented, although the coupling pin 7.1 would not prevent such.
- the axis of rotation remains 8.3 of the driving head 8.1 in the retracted position relative to the date 4 and the driving head pulls the date wheel in the upcoming interaction with only one position with it.
- Figure 4b shows the situation on the 30th day of a month with 30 days. Since the coupling pin 7.1 is located above a segment of the cam 6, which has a small radius, a run-in of the roller 7.2 in the recess 4.3 is not prevented. As a result, the coupling rocker rotates, and the rotation axis 8.3 of the driving device changes to the position closer to the date wheel. This causes the pickup head to drag the date wheel two positions in the upcoming interaction.
- Figure 4c shows the situation on the first day of the following month. The roller 7.2 has left the recess 4.3 again. Consequently, the coupling rocker has rotated back to its original position, whereby the axis of rotation 8.3 of the driving device again assumes the position of the date wheel retracted position.
- Figure 4d shows the situation on the 30th day of a month with 31 days. Since it is a month with 31 days, the coupling pin is 7.1 on a segment of the cam 6, which has a large radius. By resting the coupling pin on the segment switching of the coupling rocker and thus the axis of rotation of the driving device is prevented.
- FIG. 4e shows the situation on the 31st day of a month with 31 days.
- Both coupling pin 7.1 and the roller 7.2 now prevent switching the coupling rocker, whereby the axis of rotation 8.4 of the driving device remains in the retracted position of the date wheel.
- the driving head 8.1 pulls the date wheel 4 on this day only by one position on the first day of the following month.
- the clock has a mechanism that allows decoupling date display and its drive through the clockwork.
- the elements which in an exemplary embodiment effect the transfer of control over the date display from the drive wheel 8 to the adjustment gear 1 1 are also shown in FIG.
- This mechanism will now be explained with reference to the detailed views shown in FIGS. 3a-3c.
- the mechanism is based on a decoupling rocker 9 (FIG. 3 a), which has two oppositely angled surfaces on the end 9. 1 opposite the coupling rocker 7.
- the decoupling rocker has a coupling pin 9.3 located against a setting device 13, a spring leaf 9.2 on the side and a fixing opening 9.7, the center of the fixing opening coinciding with the axis of rotation of the decoupling rocker.
- the mechanism has a deflecting element 10.
- Figure 3b shows the situation in which the date is controlled by the mechanical annual calendar.
- the adjusting device 13 is in its maximum position embedded in the housing. In this position, deflecting element 10 and decoupling rocker 9 assume an orientation which causes a decoupling pin 7.5 mounted on the underside of a foot part 7.7 of the coupling rocker 7 to rest on the coupling surface 9.5 (see also FIGS. 7 and 3.c).
- FIG. 3 c shows the mechanism which causes the control to change over the date display from the movement to the setting device 13.
- the arrows shown in FIG. 3 c indicate directions of movements which are made by the corresponding elements during steps i to vi can.
- the decoupling pin 7.5 changes from the coupling surface 9.5 to the decoupling surface 9.6, which results in that the axis of rotation located on the coupling rocker 7 8.3 the driver head 8.1 of the date wheel 4 so far away (step iv), that the path on which the driving head moves and the circle on which the 31 teeth of the date wheel are arranged, no longer overlap.
- the date display is decoupled from the drive wheel and thus from the movement.
- the Einstell leopardrad 1 1 shown in Fig. 2 comes into contact with the display sprocket 1 and with the thread of the adjusting device 13. This makes it possible by turning the adjusting device (step v) the date both forward and backward (step vi).
