Description

Mechanism for displaying and correcting two different states of measurable time

Technical Field

The invention concerns a timepiece mechanism for displaying and correcting the state of two different measurable amounts of time of a timepiece or scientific instrument including a timepiece movement, said movement including or driving at least a first display mechanism for displaying a first measurable amount of time and at least a second display mechanism for displaying a second measurable amount of time, said movement including an adjustment member.

The invention also relates to a timepiece incorporating a display mechanism of this type.

The invention relates to the field of horology and the field of scientific equipment for displaying periodic phenomena.

The invention relates more particularly to the field of horology, and in particular to timepieces with complex functional mechanisms connected to a time display called calendar mechanism, such as a date display, a moon phase display, a tide display, a day/night display, an AM/PM display, etc.

Background

The simultaneous display of several measurable amounts of time is covered by a complex function in high-end clockmaking. However, when the correction mechanism is being operated, it is difficult to ensure the safety of the display mechanism. During a preparatory phase of an operation for driving one of the display mechanisms or during an actual driving operation, the action of the correction mechanism may interfere with the driving operation. For example, correction of the date or time is generally prohibited or at least not recommended when midnight comes. This problem is particularly acute when several display mechanisms coexist. Some safety devices properly manage the correction operations performed in a dedicated position of the stem, but there is still a risk when the user envisages the correction via a time-setting work mechanism, in particular in the opposite direction to the conventional operation.

CH patent application No.394959A to TAVANNES discloses a self-winding timepiece with a manual winding and time setting device and a date mechanism, comprising a lever pivoted about the axis of a crown wheel, and with an intermediate wheel constantly engaged with said wheel. This lever is controlled by a pull-out piece hinged to the winding stem so as to be able to occupy three positions: one position where the intermediate wheel is inactive, another position where the intermediate wheel engages with the date setting mechanism and another position where the intermediate wheel engages with the motion work. The crown wheel is constantly engaged with the winding mechanism. The lever carries a peg (stud) on which the intermediate time-setting wheel is fitted, which is a friction fit on a shoulder of the drive cam of the date mechanism. The friction spring holds the intermediate wheel and the cam fitted to each other. Depending on the position of the pull-out piece and of the lever, the trajectory of the cam intersects the trajectory of the teeth of the date disc, so that the cam drives the date disc by a value slightly less than one step of its toothing, and the jumper spring performs an additional rotation.

German utility model No.8610798U1 in the name of SCHWARTZ discloses a lunar phase and tidal indicating device in which the lunar phase wheel is actuated by a tooth of an actuating lever that is returned by a detent lever spring. The actuating lever is coupled to a first arm of a control lever, the other arm of which cooperates with a pin carried by a cam which can be disengaged from another pin carried by a control wheel which pivots about the same axis as the cam.

CH patent No.589880B5 in the name of SSIH discloses a timepiece control mechanism with two calendar parts, namely a date part and a day part, comprising a single correction lever pivoted in a thrust manner, fitted on a spindle integral with an intermediate time-setting wheel, said spindle engaging in an elongated hole of a bar-shaped clamping plate (bar) in a position determined by a toothed shaft sliding against a spring, said correction lever carrying a pivotally mounted correction wheel set permanently engaged with the intermediate wheel and alternatively engaged with one of the two calendar parts.

Disclosure of Invention

The invention provides a reliable, simple and economical solution to the safety of the display mechanism while the correction mechanism is being operated. During a preparatory phase of an operation for driving one of the display mechanisms or during an actual driving operation, the action of the correction mechanism may interfere with the driving operation. The invention is particularly applicable to the following situations: the user can use the same adjustment member to calibrate the mechanism for displaying the different measurables.

The invention therefore relates to a timepiece mechanism for displaying and correcting the status of two different measurable amounts of time of a timepiece or scientific instrument comprising a timepiece movement, said movement including or driving at least a first display mechanism for displaying a first measurable amount of time and a second display mechanism for displaying a second measurable amount of time, said movement including an adjustment member, characterized in that said first display mechanism and said second display mechanism respectively include a first drive mechanism and a second drive mechanism sharing a common drive mechanism, said common drive mechanism being driven by said movement and controlling the driving of one of said first display mechanism and said second display mechanism by instantaneous jumps and the driving of the other of said first display mechanism and said second display mechanism in a drag (drag) manner, and in that, the first display mechanism and the second display mechanism respectively include a first correction mechanism and a second correction mechanism that share a common correction mechanism driven by the adjustment member, the common correction mechanism being independent of the common drive mechanism and including at least one friction safety device that prevents any correction when preparing or performing an instantaneous display jump.

The invention also relates to a timepiece incorporating a display mechanism of this type.

Detailed Description

The invention relates to the field of horology and the field of scientific equipment for displaying periodic phenomena.

The invention relates more particularly to the field of horology, and in particular to a timepiece 1000 with a complex functional mechanism connected to a time display, called calendar mechanism, such as a date display, a moon phase display, a tide display, a day/night display, an AM/PM display, etc. These complex functions are driven by the movement 2.

The invention therefore concerns a timepiece mechanism 1 for displaying and correcting the state of at least two different measurable time quantities of a timepiece 1000 or scientific instrument including a timepiece movement 2, in particular in specific periods of use different from each other. The movement 2 comprises or drives at least: a first display mechanism 3 for displaying a first measurable amount of time and a second display mechanism 4 for displaying a second measurable amount of time. The movement 2 includes an adjustment member 50 such as a stem or the like operated by a crown.

According to the invention, the first display mechanism 3 and the second display mechanism 4 comprise a first drive mechanism 30 and a second drive mechanism 40, respectively, which share a common drive mechanism 10, the common drive mechanism 10 being driven by the movement 2 and controlling the driving of one of the first display mechanism 3 and the second display mechanism 4 by instantaneous jumps and the driving of the other of the first display mechanism 3 and the second display mechanism 4 in a dragging manner.

In the case where the movement 2 has or drives an additional display mechanism different from said first display mechanism 3 and said second display mechanism 4, each of said additional display mechanisms further comprises a drive mechanism, a part of which is formed by said common drive mechanism 10.

According to the present invention, in combination with the driving mechanism, the first display mechanism 3 and the second display mechanism 4 respectively include the first correcting mechanism 300 and the second correcting mechanism 400 that share the common correcting mechanism 100 driven by the adjusting member 50. The common correction mechanism 100 is independent of the common drive mechanism 10 and comprises at least one friction safety device 54, said friction safety device 54 preventing a correction when preparing or performing an instantaneous display jump.

In the case where the movement 2 has or drives an additional display mechanism different from the first display mechanism 3 and the second display mechanism 4, each of the additional display mechanisms further includes a correction mechanism, a part of which is formed by the common correction mechanism 100.

The invention is described below in a particular, non-limiting embodiment in which the mechanism 1 is a lunar and date mechanism 1 for a timepiece 1000 or scientific instrument comprising a timepiece movement 2. The first display means 3 is a moon phase display, and the second display means 4 is a date mechanism.

The lunar phase display mechanism 3 includes a trailing lunar phase drive mechanism 30 and a lunar phase correction mechanism 300.

The second date display mechanism 4 includes a date driving mechanism 40 of instantaneous jump and a date correcting mechanism 400.

The movement 2 comprises or drives a date mechanism and/or a mechanism for counting reference periods of duration equal to one earth day or an integer multiple or fraction thereof. The movement 2 has an output part 5 which is locked during the reference and drives the main reference display. Preferably, the output member 5 is formed by an hour wheel 5, as seen in the preferred but non-limiting embodiment shown in the accompanying drawings.

The lunar phase drive mechanism 30 and the date drive mechanism 40 mainly use the common drive mechanism 10. In the particular embodiment shown in the figures, the drive mechanism 10 comprises an intermediate date wheel 6, which intermediate date wheel 6 is in engagement with the hour wheel 5 via a roller 61 included therein. The roller 61 is formed integrally with a pinion (pinon) 62, the pinion 62 being engaged with a drive wheel plate 71 included in the drive wheel set 7, the drive wheel plate 71 being pivotally movable about an axis 70.

The driving wheel 71 for driving the date and day has an elongated opening 72 in the sector centred on the axis 70, in which the pin 73 moves. This pin 73 pivots integrally with three stacked levels (which are coaxial on the axis 70 with the drive wheel 71) all pivoting integrally:

a cam 74, this cam 74 cooperating with a release lever 9, said release lever 9 being returned towards said cam 74 by a release spring 91;

a moon phase drive disk 75 comprising radial fingers 76, said fingers 76 being able to interfere, according to their angular position, as a result of their driving, with the trajectory of star wheel 36 comprised in intermediate wheel 33, said intermediate wheel 33 being used for moon phase drive mechanism 30. The star wheel 36 comprises a toothed shaft 37 of the driving wheel 34, said wheel 34 being in particular a wheel with 59 teeth held in position by a jumper spring 35;

a date driving disc 77, which date driving disc 77 is intended for date driving mechanism 40 and comprises a date driving finger 78, the trajectory of which date driving finger 78 interferes or does not interfere with an internal toothed ring 81 of a pivotally movable date indicator 8 held by a date jumper spring 82, depending on the angular position of disc 77, so as to pivot said date indicator 8 through a single step each day at midnight.

The travel of the pin 73 in the elongated opening 72 defines a designed period of time/active time (makingsuggested). During this designed period, the lunar drive disk 75 is not driven.

Similarly, elongated opening 72 allows the date mechanism to be wound up or unwound since date driving disc 77 is not driven during the designed period.

The length of the designed period is determined by the extension of the elongated opening 72. Advantageously, said designed period is chosen to be close to seven and a half hours, which corresponds to a central angle of 110 ° for the opening 72, said angle of 110 ° being broken down into a first angle of about 90 ° required for the driving operation, to which a second safety angle is imposed, said second safety angle being chosen here in a non-limiting manner to be 20 °. These angles of course depend on the geometry of the calibre (calibre): for example, as shown in the figures, this 90 ° angle corresponds in this particular example to a central angle α during which there is interference between the trajectory of drive finger 78 and the trajectory of ring gear 81.

On the periphery of the cam 74, there are various portions that engage in pairs to form a cavity or beak.

Under the action of the release spring 91, the release lever 9 is forced against the cam 74 and tends to pivot it away from certain rest positions of the cam 74 and thus to drive in rotation the pin 73, the moon phase driving disk 75 and the date driving disk 77, which rotate integrally with one another.

Preferably, the driving wheel set 7 is made according to the characteristics of EP patent No.2015146 in the name of omega asa, in particular as regards the profile of the cam 74 and its operation according to the position of the pin 73 in the elongated opening 72. The profile of the cam 74 is therefore particularly designed to release the drive finger 78 from the date toothing 81 after the toothing 81 has been driven.

The common drive mechanism 10 according to the present invention thus combines a drive wheel set according to EP patent No.2015146 with the lunar drive disk 75. Only the date driving disc 77, together with its date driving finger 78, undergoes sudden vibrations caused by the steep slope of the cam 74, which causes instantaneous operation of the date mechanism when the beak of the release lever 9 intersects the peak of the cam 74 at midnight.

Whereas the lunar drive disk 75 only undergoes a slow movement of the pin 73 and is therefore dragged by the movement of the hour wheel 5, except during said designed period in which the hour wheel 5 remains stopped.

The winding of the lunar and date mechanisms is therefore performed gradually throughout the day, avoiding the need for a large instantaneous energy consumption. Advantageously, the lunar phase display change time is selected to be the time when other mechanisms, such as the date mechanism, have not moved, for example around 2200 hours. The position of pin 73 on lunar drive disk 75 determines the phase shift.

The drive mechanism may advantageously be uncoupled after a midnight jump in order to prevent any conflict.

Preferably, the lunar phase mechanism 30 and the date driving mechanism 40 are staggered by several hours, in particular 12 hours, in order to spread the energy consumption during the day and to prevent any interference of said mechanisms around midnight. In fact, since the lunar phase indicator is less precise than other time or date indications, it can be shifted by several hours without any problem.

The driving wheel 71 completes one revolution within 24 hours. The lunar phases are coupled, driven and changed at selected times during manufacturing in a trailing manner.

The date hopping is performed instantaneously at midnight.

In short, by using a common drive mechanism 10 according to the invention, it is easy to obtain two different displays, which are measurable differently, using the same time source in two different operating modes, and to spread the energy consumption over the course of a day. The mechanism has a reduced number of components. By combining the mechanism already manufactured according to EP patent No.2015146 with the drive disc 75 according to the invention in a reduced space requirement and in a very economical manner, it is easy to improve the mechanism.

In addition to using the common drive mechanism 10, the present invention is characterized by the incorporation of a common correction mechanism 100.

Movement 2 generally comprises a stem 50 for winding and adjusting the time and date setting. The stem 50 has a wheel or sliding wheel 51 which, in a first pulled-out position T2 of the stem 50, meshes with an intermediate wheel 55 pivoted about an axis 56.

Advantageously, and in a similar way to the drive mechanism, the lunar phase correction mechanism 300 and the date correction mechanism 400 also mainly use a common correction mechanism 100, this common correction mechanism 100 having the same correction lever 15, said correction lever 15 being used both for correcting the date when the stem 50 is operated clockwise and for correcting the lunar phase when the stem 50 is operated counterclockwise.

The assembled corrector lever 15 includes the slide lever 44 pivotally mounted on the axis 56. Preferably, the mechanism 100, and in particular the correction lever 15 thereof, incorporates the features of the instantaneous release and quick correction device of EP patent No.1785783 of the applicant.

The sliding lever 44 carries, on a first side of the pivot 56, an arm provided with a V-shaped cutout, and, on the other side of the pivot 56, a pivot 45, the pivot 45 carrying coaxially a correction star wheel 46 and a lever wheel 52, the lever wheel 52 being in mesh with an intermediate wheel 55 driven by the winding stem 50.

The correction star wheel 46 carries at least one and preferably several (in particular three) radial fingers 48, the trajectory of said fingers 48 interfering or not with the internal toothing 81 of the date indicator 8, or with the trajectory of the lunar correction lever 38, depending on the angular position of the sliding rod 44. The lever 38 is permanently pivoted back towards the spindle 45 of the correction star wheel 46 by a return spring 39. The correcting star wheel 46 is advantageously provided with a lubrication channel 47.

According to the present invention, the lever wheel 52 and the correcting star wheel 46 are pivoted integrally by the friction spring 54 without any resisting stress. Therefore, if the date driving finger 78 has engaged with the ring gear 81 of the date indicator 8 on the side of the common drive mechanism 10, there is a risk of a conflict in the case where the date correction is subsequently started. The sliding of the friction spring 54 thus protects the two date driving and correcting mechanisms 40 and 400. The same is true for the protection of the lunar phase drive and correction mechanisms 30 and 300.

Therefore, the friction spring 54 is preloaded such that the torque exerted by the friction spring 54 in order to fix the lever wheel 52 and the corrector star-wheel 46 to each other, which is exerted on the finger 48 abutting against the date ring gear 81, is lower than the lowest value among the torque transmitted by the movement 2 to drive the finger 78 of the date driving mechanism 40 or the torque exerted by the release spring 91 to the cam 74 via the release lever 9.

The rest position of the sliding rod 44 is a neutral position that does not interfere with either the date mechanism or the lunar phase mechanism.

In a conventional manner, the control lever of the time-setting mechanism of the movement (not shown in the figures) can occupy three distinct positions depending on the relative position of the stem 50 and of the pull-out member, not shown in the figures. The control lever carries a time-setting wheel train. The arbour 19 of one of the wheels of the train moves in a V-shaped groove 18 included in a small lever 17, said small lever 17 pivoting on the fixed arbour 16. The small bar 17 carries pegs 41 which are received in V-shaped cut-outs 49 included in the sliding bar 44 for holding the sliding bar 44 in position.

In the neutral position, the mandrel 19 is located in the corner of the V of the groove 18 and the peg 41 is located in the cavity at the top of the V of the cut-out portion 49.

When the stem 50 is in position T2 for correcting the phases of the moon or the dates, the time-setting control lever pivots and therefore the spindle 19 moves the small lever 17 and its peg 41 away from the sliding lever 44. The spindle 19 then comes into contact with the end of the groove 18 closest to the date indicator 8, and the position of the peg 41 depends on the direction of rotation imparted to the stem 50.

When the stem 50 is pivoted clockwise to perform date correction, the peg 41 then comes into contact with the end of the cutout portion 49 closest to the date indicator. The intermediate wheel 55 then pivots counterclockwise, and the lever wheel 52 and the correcting star wheel 46 pivot clockwise, as viewed in fig. 3. The finger 48 of the corrector star-wheel can then abut against one tooth of the toothing 81 of the date indicator 8 to move said indicator one step forward.

When the stem 50 is pivoted counterclockwise for lunar phase correction, the peg 41 comes into contact with the end of the cutout portion 49 that is most opposite to the date indicator 8, the intermediate wheel 55 then pivots clockwise, and the lever wheel 52 and the correction star wheel 46 pivot counterclockwise about their pivot pins 45, as shown in fig. 4.

Depending on the angular position of the sliding rod 44, the trajectory of the radial finger 48 of the correction star wheel 46 interferes or does not interfere with the trajectory of the lunar phase correction rod 38 pivoted back towards the arbour 45 of the correction star wheel 46.

During pivoting, the finger 48 of the corrector star wheel 46 abuts against a face or cam 38A comprised in the lunar phase correction rod 38, so that the lunar phase correction rod 38 is pivoted anticlockwise against the return spring 39. Each time when finger 48 pushes on lunar phase correction lever 38, this lever 38 drives, via beak 38B included therein, one tooth of lunar phase star wheel 34, this star wheel 34 being normally provided with 59 teeth and held by jumper spring 35. Thus, the lunar phase can be easily adjusted to its precise representation by a fast operation. During this entire operation, at the other end of the sliding lever 44, the small lever 17, which is pivotally mounted about the axis 16, rests via its peg 41 on the area of the cut-out portion 49 that is furthest from the toothing 81 of the date indicator 8.

If the date driving finger 76 has engaged with the toothing of the star wheel 36 directly connected to the lunar phase wheel 34 on the side of the common drive mechanism 30, there is a risk of conflict in the case of the subsequent start of lunar phase correction. The sliding of the friction spring 54 thus protects the two lunar phase drive and correction mechanisms 30 and 300.

Therefore, friction spring 54 is preloaded such that the torque exerted by friction spring 54 in order to fix lever wheel 52 and corrector star wheel 46 to each other (which is applied to finger 38B of lever 38 against which finger 48 of corrector star wheel 46 bears) is lower than the lowest value among the torque transmitted by movement 2 to drive finger 76 of lunar drive mechanism 30 or the torque applied by release spring 91 to cam 74 via release lever 9.

Since each rotation direction of the stem 50 corresponds to the correction of a different component, each component can be corrected only in a single direction, which improves the operational safety. Therefore, the only backward correction is a correction by the action on the motion work in the pull-out position T3 of the stem 50.

In the pulled-out position T3 of stem 50, spindle 19 is in contact with the end of groove 18 furthest from the date indicator, and peg 41 is located in the cavity at the top of the V of cut-out 49.

The combined use of the mechanism according to EP patent No.2015146 and of the friction spring 54 according to the invention prevents any risk of accidental operation, in particular in the direction opposite to the usual adjustment direction, caused by the adjustment action of the motion work when the driving or corrector wheel set has engaged the toothing of the day or month phase mechanism.

The mechanism according to the invention allows to carry out the lunar phase and date corrections completely independently and safely.

The invention also relates to a timepiece 1000 comprising a display mechanism 1 and a timepiece movement 2 of this type, said mechanism 1 being driven by said movement 2.
