Description

Technical Field

[0001] The field of the present invention relates to a timekeeping mechanism for displaying, for example, seasons by means of a drive movable object with 31 stable positions that moves by jumping over a yearly cycle period.

[0002] The present invention also relates to a mechanism for correcting a mechanism for displaying a yearly cycle period.

[0003] The present invention also relates to a watch movement having a mechanism for displaying a yearly cycle period and a date mechanism.

[0004] The present invention also relates to a timepiece, for example, a wristwatch.

Background Art

[0005] The yearly cycle, and in particular the mechanism for displaying the period of this yearly cycle, enables the display of information related to a given period during the solar yearly cycle.

[0006] The mechanism for displaying the period of the yearly cycle is generally a mechanism with a jump drive that enables positioning an indicator facing the scale or division of the dial. The yearly cycle can be divided into several periods corresponding to the scale or division of the dial. However, these jump-type mechanisms for displaying the period of the yearly cycle are not very accurate because they cannot convey to the user whether the displayed period is at the beginning or end of the yearly cycle.

[0007] For example, when such a mechanism for displaying the period of the yearly cycle enables indicating months or, for example, seasons, the pointer indicates the current period (month or season), but does not display more accurate information regarding the time remaining within the current period. As a result, the jump drive in these displays creates a "display error" with respect to the actual situation regarding the current period.

[0008] To overcome this drawback, the document European Patent No. 0397028 provides a yearly period display mechanism driven by a drive mechanism with 31 gears that directly engage with the date wheel. When the appropriate gear ratio is used, the yearly period display rotates once for every 372 steps of the drive mechanism. In other words, the yearly period display rotates once for every 12 complete rotations of the drive mechanism, and the drive mechanism engaged with the date display rotates once for every month.

[0009] Thus, when using such a display mechanism, it becomes possible to improve the accuracy of such jump-driven displays by driving the annual cycle display once a day rather than once a period.

[0010] However, such a date-driven annual display mechanism requires the user to manually adjust the date up to 372 times, which is time-consuming to set up. This is considered an ergonomic setup and leaves the user with the impression that it is not a very high-end timepiece. [Prior art documents] [Patent Documents]

[0011] [Patent Document 1] European Patent No. 0397028 [Overview of the project] [Problems that the invention aims to solve]

[0012] Therefore, in order to address at least one of the aforementioned problems, it is necessary to improve this jump-type mechanism for displaying a yearly period driven by a movable part with 31 stable date display positions, and more specifically, the mechanism for correcting such a display mechanism. [Means for solving the problem]

[0013] In this regard, the present invention proposes a watch movement comprising a mechanism for displaying a yearly period that operates in stages daily, which is driven by a driveable mechanism with 31 stable positions, and which comprises a rapid correction mechanism for independently correcting the yearly period display via the winding stem pull-out position of the watch movement.

[0017] Prioritizing the display of the annual period, the mechanism for displaying the stellar period is the same as the mechanism for displaying the stellar period.

[0018] Prioritizing the display of annual cycles, the mechanism for displaying the seasons in China is the same as the mechanism for displaying the seasons in China.

[0019] In addition to the characteristics described in the previous sections, the watch movement according to the present invention has the following characteristics: - The annual periodic drive gear is kinematically linked in rotation to the annual periodic compensating gear via a compensating wheel that works in cooperation with a compensating jumper configured to ensure that the compensating wheel is kept in a stable position when the watch movement is operating normally. - The corrective axle is integrated with the annual corrective gear in a rotating state, and the corrective jumper is supported by the annual drive gear, or the corrective axle is integrated with the annual drive gear in a rotating state, and the corrective jumper is supported by the annual corrective gear. - The corrective star vehicle has six branches. -By using a winding stem to correct the component that indicates the period of the annual cycle, the indexing between the annual cycle drive gear and the annual cycle correction gear is changed by a jump, and as a result the component that indicates the period of the annual cycle is corrected by a 30° jump. -31 The resulting gear ratio of the annual gear train between the drive mechanism with a stable position and the member for indicating the annual period is 12, and consequently the member for indicating the annual period rotates once completely after the drive mechanism with a stable position of 31 has rotated 12 times completely. - The mechanism for displaying the annual cycle is a mechanism for displaying the seasons, and preferably the seasons of China.

[0022] The objects, advantages, and characteristics of the present invention will become apparent from the following detailed description with reference to the following figures.

[Figure 2] A view of the watch movement shown in FIG. 1 as seen from below is schematically illustrated. [Figure 3] A schematic view of a watch movement 1 according to the present invention is illustrated. [Figure 4] A schematic view of a timepiece comprising a watch movement according to the present invention is shown.

Embodiments for Carrying Out the Invention

[0024] In all the figures, common elements have the same reference number unless otherwise specified.

[0025] Figure 1 schematically illustrates a top view of a watch movement 1 according to the present invention, which includes a date mechanism 50 and a mechanism for displaying a period of 100 years in a year cycle, driven by a drive mechanism 55 with position 31 of the date mechanism 50.

[0026] Figure 2 provides a schematic example of a view of the watch movement 1 shown in Figure 1, viewed from below.

[0027] Figure 3 is a schematic diagram of the watch movement 1 according to the present invention.

[0028] Figure 4 schematically illustrates a timekeeping device 200 comprising a case 210 housing a watch movement 1 according to the present invention. For example, the timekeeping device 200 is a wristwatch.

[0029] The watch movement 1 typically comprises a partially shown regulating gear train 10, which has divisible parts in the details that drive the time gear, and the regulating gear train assembly is configured such that the time gear completes one full rotation in 12 hours.

[0030] The regulating gear train typically supports the hour hand 2 (which can be seen in Figure 4), which is driven, for example, by the axis of the time gear.

[0031] The watch movement 1 according to the present invention includes a date mechanism 50 kinematically connected to the regulating gear train 10.

[0032] The date mechanism 50 typically includes a 24-hour gear 52 kinematically connected to the time gear of the governor train 10 via an intermediate movable part 51, as shown in Figures 1 and 2, for example.

[0033] The 24-hour gear 52 supports a finger 53 that is configured to work in conjunction with the date lever 54 to move the date lever 54 once a day each time the 24-hour gear 52 rotates.

[0034] The date lever 54 comprises a first arm 54a and a second arm 54b that extend on both sides of the pivot axis P1. The date lever 54 is actuated by a spring (not shown) that moves the first arm 54a toward the finger 53.

[0035] The end of the second arm 54b is provided with a lever head 54c that ends with a lever beak 54d configured to cooperate with the teeth of the driveable 55 having position 31 of the date mechanism 50.

[0036] Thus, once a day, the finger 53 moves the date lever 54 so that it comes into contact with the end of the first arm 54a. Under the pressure of the finger 53, the date lever 54 pivots around its pivot axis P1 so that the lever beak 54d comes into contact with the teeth of the drive mechanism 55 having position 31, and rotates the drive mechanism 55 having position 31 by one step.

[0037] At each stage, the driveable 55 having position 31 is held in a stable position by the jumper 56, and the jumper (not shown) is configured to push the jumper 56 back toward the teeth of the driveable 55 having position 31.

[0038] The drive mechanism 55, with position 31, meshes with a date gear train 150 which includes, for example, an intermediate mechanism 151 and a date display gear 152 with a pivot 153 suitable for receiving a day hand 3 that forms a date indicator (which can be seen in Figure 4). The date indicator 3 may also have other forms.

[0039] The date mechanism 50 also includes a date correction member 250, such as a push button, that acts on a correction lever 251 having a correction beak 252 at one end configured to start the date lever 54 each time the date correction member 250 is acted upon. More specifically, the correction beak 252 presses the lever head 54c so as to act on the teeth of the drive mechanism 55 having position 31 by one step via a lever beak 54d acting on the teeth of the drive mechanism 55 having position 31. In this way, each time the date correction member 250 is acted upon, the drive mechanism 55 having position 31 and the date hand 3 can be corrected by one step.

[0040] The watch movement 1 also includes a mechanism for displaying a period of 100 years in a yearly cycle, which is driven by a drive mechanism 55 having 31 positions of the date mechanism 50, or more specifically, by a drive mechanism 55 having 31 positions of the date mechanism 50.

[0041] Mechanisms for displaying a 100-year cycle could include those for displaying months, weeks, constellations, the Chinese zodiac, equation of time, working equation of time, Christian holidays, the spring and autumn equinoxes and the summer and winter solstices, climatic seasons, the Earth's tilt relative to the sun, Chinese seasons, or even sidereal cycles.

[0042] Prioritizing the display of a 100-year cycle, the mechanism for displaying months, seasons, or even Chinese seasons is also a mechanism for displaying months, seasons, or even Chinese seasons.

[0043] The mechanism for displaying a period of 100 years includes a component for indicating a period of 110 years.

[0044] In a representative embodiment illustrated here, the component for indicating the annual period 110 includes, for example, an annual period indicator gear 112 (which can be seen in more detail in Figure 2) with a central shaft 113 suitable for receiving a needle 4 that forms an annual period indicator (which can be seen in Figure 4).

[0045] According to a modified embodiment, the annual period display gear 112 can rotate a disk having an indicator, index, or scale on its upper surface corresponding to the period of the annual period to be displayed.

[0046] Depending on the desired display type, the disc may be fully or partially visible through an opening appropriately shaped within the dial of the timepiece 200.

[0047] When the watch movement 1 is functioning normally, the component for indicating the period 110 of the annual cycle is driven by an annual cycle gear train 120 which is directly driven by a driveable component 55 having 31 positions.

[0048] In the illustrated example, the driveable gear 55, with position 31, meshes with the gear 121a of the first intermediate driveable gear 121. The first intermediate driveable gear 121 includes a pinion 121b that meshes with the gear 122a of the second intermediate driveable gear 122. The second intermediate driveable gear 122 includes a pinion 122b that meshes with the annual periodic drive gear 123.

[0049] The annual cycle drive gear 123 is kinematically connected in rotational mode to the annual cycle correction gear 124, which is coaxial with the annual cycle drive gear 123 and meshes with the annual cycle display gear 112 that supports the annual cycle period indicator 4.

[0050] According to the present invention, the annual periodic drive gear 123 is rotationally coupled to the annual periodic correction gear 124 by a correction wheel 162 positioned between the two gears 123 and 124. The correction wheel 162 works in cooperation with a correction jumper 163 associated with its own spring (not shown), and the correction jumper 163 is configured to ensure that the correction wheel 162 is kept in a stable position when the watch movement 1 is operating normally. Thus, the correction wheel 162 and the correction jumper 163 form a coupling device that can change the indexing between the two gears 123 and 124 by the annual periodic correction mechanism 400 described below.

[0051] According to the representative embodiment shown, the compensating star wheel 162 is integrated with the annual periodic compensating gear 124 in a rotational state, and the compensating jumper 163 is supported by the annual periodic drive gear 123, for example, via a pin 164. Naturally, the compensating jumper 163 can rotate around this pin 164, which forms a pivot axis for the compensating jumper 163, and as a result can cooperate with various branches of the compensating star wheel 162.

[0052] According to an alternative embodiment, the correction jumper 163 is a deflection jumper spring configured to allow the indexing between the annual periodic drive gear 123 and the annual periodic correction gear 124 to be changed, while ensuring that the correction star wheel 162 is kept in a stable position when the watch movement 1 is operating normally.

[0053] In the modified embodiment, the correction star wheel 162 can be integrated with the annual period indicator gear 123, and the correction jumper 163 can be supported by the annual period correction gear 124.

[0054] Thus, when the watch movement 1 is operating normally, the rotation of the annual cycle drive gear 123, driven by the driveable mechanism 55 with position 31, rotates the annual cycle correction gear 124, which is connected to the annual cycle drive gear 123 in a rotating state. The annual cycle correction gear 124 then drives the annual cycle display gear 112, which supports the annual cycle period indicator 4.

[0055] Preferably, the gear ratio of the resulting annual cycle gear train 120 between the drive mechanism 55 with position 31 and the member indicating the annual cycle period 110 is 12, meaning that the member indicating the annual cycle period 110 completes one full rotation after 12 months, resulting in 372 jumps (in other words, 12 x 31 jumps) for the drive mechanism 55 with position 31 and the day hand 3.

[0056] Thus, in the illustrated example, the annual period indicator 4 is driven daily by a driveable mechanism 55 with position 31, with a jump of 0.9677° per day.

[0057] The watch movement 1 also includes a year-cycle correction mechanism 400 that allows the angular position of the year-cycle indicator gear 112 to be corrected by rotating the winding stem 410 around its axis of rotation at a given axial position of the winding stem 410, independently of the date.

[0058] Typically, the winding stem 410 can move axially along its axis of rotation between different axial positions corresponding to different functions of the watch movement 1, such as manually winding the movement, setting the time, setting the date, and / or setting other indicators.

[0059] For example, the winding stem 410 has a first axial position T1 which is a neutral pushed-in position corresponding to the winding position of the watch movement 1, enabling the winding of the barrel spring. In this first axial position T1, the winding stem 410 is fully pushed in toward the case 210 of the timepiece 200.

[0060] For example, the winding stem 410 has a second axial position T2 that corresponds to a position for setting the year period indicator gear 112, which is in a first pulled-out position relative to a neutral pushed-in position.

[0061] For example, the winding stem 410 has a third axis position T3 that is in a second pulled-out position relative to a neutral pushed-in position and corresponds to a position for setting the watch movement 1, for example, a position for setting the time.

[0062] To reach the second axis position T2, the user pulls the crown of the winding stem 410 axially from the neutral position T1 and moves the crown axially toward the outside of the case 210 of the timepiece 200.

[0063] To reach the third axis position T3, the user pulls the crown of the winding stem 410 axially from the second axis position T2 and moves the crown axially toward the outside of the case 210 of the timepiece 200.

[0064] Figure 1 schematically shows the position of the crown of the winding stem 410 at various axial positions T1, T2, and T3 of the winding stem 410.

[0065] Naturally, the winding stem 410 may have other pull-out positions depending on the needs and complexity of the watch movement 1.

[0066] At this second axial position T2, the sliding pinion of the winding stem 410, which has an axial displacement opposite to the axial displacement of the winding stem 410 along the axis of rotation, is moved to engage with a gear train of intermediate gears (not shown) configured to mesh with a compensator 415 having at least one actuation finger.

[0067] In the illustrated representative embodiment, the compensator 415 comprises five fingers evenly distributed around the edge of the compensator 415, and as a result, the annual period can be corrected more quickly by rotating the winding stem 410.

[0068] The compensator 415 is configured to cooperate with the teeth of the annual period compensator star wheel 416, which is integrated with the intermediate annual period compensator gear 417 in a rotating state.

[0069] The compensator 415 is mounted on a sliding gear assembly, and as a result, by rotating the winding stem 410 in a predetermined rotational direction, for example clockwise, it becomes possible to engage the compensator 415 with the teeth of the annual period compensator wheel 416 and rotate the compensator 415, for example counterclockwise.

[0070] The intermediate annual period correction gear 417 meshes with the annual period correction gear 124. In this way, by rotating the winding stem 410, the annual period correction gear 124 becomes rotatable by changing the indexing between the annual period drive gear 123 and the annual period correction gear 124 when it moves beyond the range of the coupling force generated by the correction jumper 163 and the spring of the correction jumper 163 cooperating between two consecutive teeth of the correction star wheel 152.

[0071] The winding stem 410 allows for quick correction of the member to indicate a period of the year cycle, for example, by a jump corresponding to a jump period of one month or 31 days, or by a 30° jump of the member to indicate a period of the year cycle, for example, when the dial has 12 indices divided over 360°.

[0072] The watch mechanism 1 operates as follows: When the timekeeping device 200 is functioning normally, the drive mechanism 55, having position 31, is driven by the regulating gear train 10 one step per day, as described above, via the finger 53 acting on the date lever 54.

[0073] The drive mechanism 55, which has 31 positions, rotates the intermediate mechanism 151 and the date display gear 152 that supports the date indicator 3 by one step per day.

[0074] The drive mechanism 55, having position 31, also rotates the first intermediate mechanism 121 of the annual cycle gear train 120. The first intermediate mechanism 121 then drives the second intermediate mechanism 122 of the annual cycle gear train 120, which then meshes with the annual cycle drive gear 123. Without any particular action on the annual cycle correction mechanism 400 and the winding stem 410, the annual cycle drive gear 123 connects with the annual cycle correction gear 124, and as a result of rotating the annual cycle drive gear 123, the annual cycle indicator gear 112 and the annual cycle indicator 4 are rotated by only one step per day, or 0.9677°.

[0075] If the date indicator 3 needs to be corrected, the user uses the date correction member 250. Whenever the date correction member 250 is applied, the date lever 54 acts on the drive mechanism 55, which has a position 31 that is driven by only one step.

[0076] If it is necessary to correct the component to indicate a period 110 of the annual cycle, the user positions the winding stem 410 at a corresponding axial position which is a second axial position T2 in the representative embodiment described, positioned between the winding position T1 and the time setting position T3.

[0077] When the winding stem 410 is in this position, the sliding pinion of the winding stem 410 engages with the intermediate compensating gear in the gear train of the intermediate gear. When the user rotates the winding stem 410 in a predetermined rotational direction, the intermediate compensating gear is driven, and the intermediate compensating gear drives the gear train of the intermediate gear until the compensator 415 is then rotated.

[0078] By rotating the compensator 415, the annual period compensator wheel 416 is rotated, and therefore the intermediate annual period compensator gear 417, which is integrated with the annual period compensator wheel 416 in a rotating state, is rotated.

[0079] The intermediate annual cycle correction gear 417 meshes with the annual cycle correction gear 124.

[0080] In this way, rotating the annual period correction gear 124 causes the annual period correction gear 124 to move beyond the range of the indexing linkage formed by the cooperation of the correction wheel 162 and the correction jumper 163, changing the relative position of the annual period correction gear 124 with respect to the annual period drive gear 123, which is engaged with the drive mechanism 55 with the positions of the annual period gear train 120 and 31, thereby rotating the annual period indicator gear 112.

[0081] In the representative embodiment shown, the compensating wheel 162 has six branches, and the gear ratio between the annual period compensating gear 124 and the annual period indicator gear 112 is 1 / 2. Thus, the annual period indicator gear 112 is compensated by jumps when it rotates over an angle of 30°, which is equivalent to a one-month compensation, i.e., 31-step compensations of the driveable 55 with 31 positions. This is made possible by the 1 / 2 ratio between the annual period indicator gear 112 and the annual period compensating gear 124, as each jump in the six-branch compensating wheel 162 corresponds to a 60° rotation of the compensating wheel 162 and, accordingly, the annual period compensating gear 124.

[0082] Naturally, the correcting star wheel 162 may have a different number of branches, and the gear ratio between the year-period correcting gear 124 and the year-period indicator gear 112 must be adapted according to the above ratio and the number of branches of the correcting star wheel 162, so that the year-period indicator gear 112 is corrected by a 30° jump when the dial is divided into 12 year-period periods.

[0083] Other configurations are possible without departing from the scope of the present invention.

[0084] Thus, there are two methods for correcting the member that indicates the period 110 of the annual cycle: one is to correct the driveable 55 with position 31 via the date correction member 250 in stages, and the other is to rotate the winding stem 410 in a predetermined rotational direction more quickly.

[0085] The watch mechanism 1 according to the present invention offers several advantages. Since the mechanism for displaying a period of 100 years is indexed by the date mechanism 50, the year period display will never lag and will always be indexed to that date, provided that the date mechanism is kept up-to-date by making appropriate corrections, for example, over a shorter number of months.

[0086] Therefore, such a mechanism is particularly accurate compared to a mechanism for displaying a period of the year cycle that is not connected to a date mechanism or a date-driven movable with 31 stable positions. [Explanation of Symbols]
