Description

TECHNICAL FIELD

[0001] The present utility model relates to a mechanism for displaying a period of the year (for example, a season) in a timepiece, which mechanism is driven in a jumping manner by a driving wheel having 31 stable positions.

[0002] The present utility model also relates to a mechanism for adjusting a display of a period of the year.

[0003] The present utility model also relates to a movement of a timepiece comprising a mechanism for displaying a period of the year and a calendar mechanism.

[0004] The present utility model also relates to a timepiece, for example, a wristwatch. BACKGROUND

[0005] A mechanism for displaying a period of the year (and in particular, a mechanism for displaying a period of the year) makes it possible to display information relating to a specific period during the solar year.

[0006] A display of a period of the year generally comprises a jumping drive, which makes it possible to align a hand with the graduation or division of a dial. A period of the year can be divided into several periods, which are aligned with the graduation or division of a dial. However, these jumping mechanisms for displaying a period of the year are not very accurate, since they do not make it possible to display to the user whether he is at the beginning or at the end of the period of the year being displayed.

[0007] For example, when such a device for displaying a period of the year makes it possible to display a month or a season, the hand displays the current period (month or season), but does not display more precise information about the time remaining in the current period. Thus, the jumping drive of these displays can lead to "display errors" that do not correspond to the actual state of the current period.

[0008] To remedy this drawback, document EP 0397028 proposes a device for displaying a period of the year, which is driven directly by a driving wheel having 31 teeth, in engagement with a calendar wheel. With a suitable gear ratio, the driving wheel makes 372 steps for one revolution of the display of the period of the year. In other words, the driving wheel makes twelve complete revolutions for one revolution of the display of the period of the year, and the driving wheel is in engagement with the calendar wheel, which makes one complete revolution per month.

[0009] Thus, with such a display mechanism, it is possible to improve the display accuracy of such a jumping drive device by driving the display of the period of the year once per day instead of once per period.

[0010] However, this display mechanism of the period of the year driven by the calendar is very time-consuming to set, since it requires up to 372 manual adjustments of the calendar, which is considered to be an ergonomically unsuitable setting, which gives the user the impression that the timepiece is not attractive.

[0011] It is therefore necessary to improve such a display mechanism of the period of the year, driven in a leap manner by a wheel of the calendar having 31 stable positions, and in particular the regulating mechanism of such a display mechanism, in order to solve at least one of the above-mentioned problems. Summary of the invention

[0018] - a period of the year regulating mechanism configured to quickly and independently regulate the display mechanism of the period of the year by rotating the winding stem shaft to a first extracted position; the regulating mechanism being configured so that the rotation of the winding stem shaft drives the period of the year regulating wheel in rotation and changes the indexing between the period of the year driving wheel and the period of the year regulating wheel, by overriding the coupling existing between the period of the year driving wheel and the period of the year regulating wheel.

[0019] According to the invention, the display mechanism of the period of the year can be a mechanism for displaying the month, the week, the zodiac, the twelve astrological signs, the equation of time, the equation of the hour, Christian holidays, solstices and equinoxes, climatic seasons, the inclination of the Earth relative to the Sun, Chinese seasons or solar terms.

[0040] Figure 1 A top view of a clock movement 1 according to the utility model is schematically shown, the movement comprising a calendar mechanism 50 and a display mechanism 100 of the period of the year in a leap year, driven by a 31 -position driving wheel 55 in a leap year.

[0041] Figure 2 A bottom view of the clock movement 1 shown is schematically shown. Figure 1

[0042] Figure 3 is a block diagram of a clock movement 1 according to the utility model.

[0043] Figure 4 A timepiece 200 is schematically shown, the timepiece comprising a watch case 210, the watch case housing a clock movement 1 according to the utility model. For example, the timepiece 200 is a wristwatch.

[0044] The clock movement 1 generally comprises a time train 10 (partially shown), in particular comprising a cross that drives a time wheel, the time train assembly being configured to make the time wheel turn a full circle in 12 hours.

[0045] The time wheel is generally provided with an hour indicator, for example a time hand 2 (not shown). Figure 4 ​​The time wheel is driven by the shaft of the time train.

[0046] The timepiece movement 1 according to the application comprises a calendar mechanism 50 kinematically connected to the time train 10.

[0047] The calendar mechanism 50 generally comprises a 24-hour wheel 52 kinematically connected (as shown in Figure 1 and Figure 2 intermediate wheel 51) to the hour wheel of the time train 10.

[0048] The 24-hour wheel 52 is provided with a pawl 53 for cooperating with a calendar jumper 54, which is actuated one step per day by the 24-hour wheel 52.

[0049] The calendar jumper 54 comprises a first arm 54a and a second arm 54b, which extend to either side of the axis of rotation P1. The calendar jumper 54 is biased by a spring (not shown) to tend to adjust the position of the first arm 54a towards the pawl 53.

[0050] The end of the second arm 54b comprises a jumper head 54c, the end of which is a jumper tip 54d, which is configured to cooperate with the teeth of a 31 -position drive wheel 55 of the calendar mechanism 50.

[0051] The pawl 53 thus drives the calendar jumper 54 once per day by contact with the end of the first arm 54a. Under the thrust of the pawl 53, the calendar jumper 54 rotates about its pivot P1, thereby bringing the jumper tip 54d into contact with the teeth of the 31 -position drive wheel 55 and driving it to rotate one step.

[0052] At each step, the 31 -position drive wheel 55 is held in a stable position by a calendar jumper spring (not shown) and a calendar jumper lever 56, which is pushed against the teeth of the 31 -position drive wheel 55.

[0053] The 31 -position drive wheel 55 meshes with a calendar train 150, which can comprise an intermediate wheel 151 and a calendar display wheel 152, which has an axle 153 suitable for receiving a calendar hand 3 (visible in Figure 4 ). The calendar hand 3 can also take other forms.

[0054] The calendar mechanism 50 also comprises a calendar corrector member 250, such as a push rod, acting on a corrector pin 251, one end of which comprises a corrector tip 252 configured to cause the calendar pin to be advanced each time the calendar corrector member 250 is actuated. More specifically, the corrector tip 252 bears against the pin head 54c in order to drive the 31 -position drive wheel 55 one step by acting on the pin head 54d, which bears against the teeth of the 31 -position drive wheel 55. Thus, each actuation of the calendar corrector member 250 causes the 31 -position drive wheel 55 to be advanced one step, thereby causing the calendar hand 3 to be advanced one step.

[0055] The timepiece movement 1 also comprises a period-of-year display mechanism 100, which is jumped by the calendar mechanism 50, and more particularly by the 31 -position drive wheel 55 of the calendar mechanism 50.

[0056] The period-of-year display mechanism 100 can be a mechanism for displaying the month, the week, the zodiac sign, the twelve astrological signs, the equation of time, the true equation of time, Christian holidays, solstices and equinoxes, climatic seasons, the inclination of the Earth with respect to the Sun, Chinese seasons or solar terms.

[0057] Preferably, the period-of-year display mechanism 100 is a mechanism for displaying the month, the season or even the Chinese season.

[0058] The period-of-year display mechanism 100 comprises a period-of-year indicator member 110.

[0059] In the example shown in the figures, the period-of-year indicator member 110 comprises a period-of-year display wheel 112 (visible mainly in Figure 2 which has an axle 113 suitable for receiving, for example, the hand 4 constituting the indicator of the period of the year to be displayed (visible in Figure 4 ).

[0060] According to an implementation variant, the period-of-year display wheel 112 can be a rotating driven disc, the upper face of which bears an indication, a hand or a scale corresponding to the period of the year to be displayed.

[0061] Depending on the type of display required, the disc can be wholly or partially visible through an opening of suitable shape provided in the dial of the timepiece 200.

[0062] During normal operation of the timepiece movement 1, the period-of-year indicator member 110 is driven by the period-of-year wheel train 120, which is driven directly by the 31 -position drive wheel 55.

[0063] In the illustrated example, the 31 -position drive wheel 55 engages with a wheel 121 a of a first intermediate wheel 121. The first intermediate wheel 121 comprises a pinion 121 b which engages with a wheel 122a of a second intermediate wheel 122. The second intermediate wheel 122 comprises a pinion 122b which engages with an annual cycle drive wheel 123.

[0064] The annual cycle drive wheel 123 is in rotational motion connection with an annual cycle regulating wheel 124 which is coaxial with the annual cycle drive wheel 123 and which engages with an annual cycle display wheel 112 carrying annual cycle hour indicators.

[0065] According to the invention, the annual cycle drive wheel 123 is in rotational connection with the annual cycle regulating wheel 124 via a regulating star wheel 162 located between the two wheels 123, 124. The regulating star wheel 162 cooperates with a regulating positioning lever 163 which is combined with its spring (not shown), the regulating positioning lever 163 being intended to ensure that the regulating star wheel 162 remains in a stable position during normal operation of the timepiece movement 1. Thus, the regulating star wheel 162 and the regulating positioning lever 163 constitute a coupling device, the graduation between the two wheels 123, 124 of which can be adjusted by means of an annual cycle regulating mechanism 400 which will be described hereinafter.

[0066] According to the illustrated embodiment, the regulating star wheel 162 is integral in rotation with the annual cycle regulating wheel 151, whereas the regulating positioning lever 163 is carried by the annual cycle drive wheel 123 via a pin 164 for example. Of course, the regulating positioning lever 163 can rotate about this pin 164 which constitutes the pivot of the regulating positioning lever 163, making it possible to cooperate with each tooth of the regulating star wheel 162.

[0067] According to an alternative embodiment, the regulating positioning lever 163 is a flexible spring positioning lever which is configured to be able to vary the graduation between the annual cycle drive wheel 123 and the annual cycle regulating wheel 124, while ensuring that the regulating star wheel 162 remains in a stable position during normal operation of the timepiece movement 1.

[0068] In a variant embodiment, the regulating star wheel 162 is integral with the annual cycle display wheel 123, whereas the regulating positioning lever 163 can be carried by the annual cycle regulating wheel 124.

[0069] Thus, during normal operation of the timepiece movement 1, the annual cycle drive wheel 123 is driven by the rotation of the 31 -position drive wheel 55, which in turn drives the annual cycle regulating wheel 124, the annual cycle regulating wheel 124 being in rotational connection with the annual cycle drive wheel 123. The annual cycle regulating wheel 124 in turn drives the annual cycle display wheel 112 carrying annual cycle hour indicators.

[0070] Preferably, the gear ratio of the annual cycle train 120 between the 31 -toothed driving wheel 55 and the annual period indicator member 110 is 12, that is to say, the annual period indicator member 110 makes a complete revolution after 12 months, that is to say, 372 jumps of the 31 -toothed driving wheel 55 and the calendar hand 372 (i.e. 12 x 31 jumps).

[0071] Thus, according to the illustrated example, the annual period indicator 4 is driven by the 31 -toothed driving wheel 55, which jumps 0.9677 degrees per day.

[0072] The timepiece movement 1 further comprises an annual cycle setting mechanism 400, by rotating the winding stem 410 around its axis of rotation at a given axial position of the winding stem 410, it is possible to adjust the angular position of the annual cycle display wheel 112 without affecting the calendar.

[0073] Generally, the winding stem 410 is axially movable along its axis of rotation between different axial positions, which correspond to different functions of the timepiece movement 1, such as winding the barrel spring, setting the time, setting the date and / or adjusting other indicators.

[0074] For example, the winding stem 410 has a first axial position T1, which is a neutral advancement position corresponding to a winding position of the timepiece movement 1, enabling to wind the barrel spring. In this first axial position T1, the winding stem 410 is fully pushed towards the case 210 of the timepiece 200.

[0075] For example, the winding stem 410 has a second axial position T2, which is a first pull-out position with respect to the neutral advancement position, corresponding to an adjustment position of the annual cycle display wheel 112.

[0076] For example, the winding stem 410 has a third axial position T3, which is a second pull-out position with respect to the neutral advancement position, corresponding to an adjustment position of the timepiece movement 1, such as a time setting position.

[0077] To reach the second axial position T2, the user needs to axially pull the winding stem of the winding stem 410, axially moving it towards the outside of the case 210 of the timepiece 200.

[0078] To reach the third axial position T3, the user needs to axially pull the winding stem of the winding stem 410 from the second axial position T2, axially moving it towards the outside of the case 210 of the timepiece 200.

[0079] Figure 1 A schematic view showing the winding stem of the winding stem 410 in different axial positions T1, T2, T3.

[0080] Of course, the winding stem 410 can have other pull-out positions, depending on the needs and complexity of the timepiece movement 1.

[0081] In the second axial position T2, the axial displacement of the sliding pinion of the upper barrel 410 is opposite to the axial displacement of the upper barrel 410, engages along the axis of rotation with a pinion wheel set (not shown) which engages with an adjuster 415 consisting of at least one driving pawl.

[0082] In the illustrated embodiment, the adjuster 415 has 5 pawls evenly distributed on its circumference, so as to allow a faster adjustment of the annual period by rotation of the upper barrel 410.

[0083] The adjuster 415 is configured to cooperate with the teeth of an annual period adjuster 416 which rotates integrally with an annual period adjustment intermediate wheel 417.

[0084] The adjuster 415 is mounted on the sliding pinion, so that, when the upper barrel 410 is rotated in a predetermined direction of rotation (for example, clockwise), the adjuster 415 engages with the teeth of the annual period adjustment star wheel 416 and causes the adjuster 415 to rotate (for example, counterclockwise).

[0085] The annual period adjustment intermediate wheel 417 engages with the annual period drive wheel 124. Thus, rotation of the upper barrel 410 allows the annual period drive wheel 124 to be driven in rotation, by varying the indexing of the annual period adjustment wheel 124 between the annual period drive wheels 123, until the coupling force generated by the adjustment positioning lever 163 and its spring is overcome and engagement is made between two consecutive teeth of the adjustment star wheel 162.

[0086] The upper barrel 410 allows the annual period indicator 110 to be quickly adjusted, for example, by a jump corresponding to a period of a month or a calendar corresponding to 31 jumps, or, for example, when 12 graduations on the dial are distributed over 360°, the annual period indicator jumps by 30°.

[0087] The watch movement 1 works as follows: when the timepiece 200 is working normally, the 31 -position drive wheel 55 is driven by the time train 10, which acts on the calendar jumper lever 54 by means of the pawl 53, which, as mentioned above, advances one step per day.

[0088] The 31 -position drive wheel 55 drives the intermediate wheel 151 and the calendar display wheel 152, which carries the calendar indicator 3, one step per day.

[0089] The 31 -tooth drive wheel 55 also drives the rotation of a first intermediate wheel 121 of the annual cycle wheel train 120. The first intermediate wheel 121 in turn drives a second intermediate wheel 122 of the annual cycle wheel train 120, which is in engagement with an annual cycle drive wheel 123. Without any special operation of the annual cycle regulating mechanism 400 and the winding stem shaft 410, the annual cycle drive wheel 123 is coupled with an annual cycle regulating wheel 124, so that the rotation of the annual cycle drive wheel 123 results in a rotation of the annual cycle display wheel 112 and the annual cycle indicator 4 by one step per day, i.e. by 0.9677°.

[0090] If it is necessary to regulate the calendar indicator 3, the user can use the calendar regulating member 250. Each activation of the calendar regulating member 250 drives the calendar jockey lever 54, which in turn acts on the 31 -tooth drive wheel 55 so that it is driven by one step.

[0091] If it is necessary to regulate the indicator member 110 of the annual cycle hour period, the user can position the winding stem shaft 410 in the corresponding axial position, in the illustrated example the second axial position T2, between the winding position T1 and the time setting position T3.

[0092] In this position of the winding stem shaft 410, the sliding pinion of the winding stem shaft 410 is in engagement with the pinion set of the regulating pinion wheel. When the user rotates the winding stem shaft 410 in the predetermined direction of rotation, the regulating pinion wheel is driven, which in turn drives the pinion set until the rotation of the regulator 415.

[0093] The rotation of the regulator 415 causes the rotation of the annual cycle regulator star wheel 416, which in turn causes the rotation of the annual cycle regulating intermediate wheel 417 integral with the annual cycle regulator star wheel 416.

[0094] The annual cycle regulating intermediate wheel 417 is in engagement with the annual cycle regulating wheel 124.

[0095] Therefore, the rotation of the annual cycle regulating wheel 124 overcomes the indexing coupling formed by the regulating star wheel 162 and the regulating positioning lever 163, resulting in the rotation of the annual cycle display wheel 112, which in turn changes the relative position of the annual cycle regulating wheel 124 with respect to the annual cycle drive wheel 123, which is in engagement with the annual cycle wheel train 120 and the 31 -tooth drive wheel 55, causing the rotation of the annual cycle display wheel 112.

[0096] In the illustrated embodiment, the adjustment star 162 comprises 6 teeth and the gear ratio between the annual cycle adjustment wheel 124 and the annual cycle display wheel 112 is 1 / 2. Thus, the annual cycle display wheel 112 is adjusted in jumps by 30° of rotation, which corresponds to the adjustment of one month, i.e. 31 steps of the 31 -position drive wheel 55. This is possible because the gear ratio between the annual cycle display wheel 112 and the annual cycle adjustment wheel 124 is 1 / 2, since each jump of the 6-tooth adjustment star 162 is a rotation of 60° of the adjustment star 162 and thus also of the annual cycle adjustment wheel 124.

[0097] Of course, the adjustment star 162 can have a different number of teeth, the gear ratio between the annual cycle adjustment wheel 124 and the annual cycle display wheel 112 must then be adjusted in accordance with the above gear ratio and the number of teeth of the adjustment star 162, so that the annual cycle display wheel 112 can be adjusted in jumps of 30° when the dial is divided into 12 periods in the annual cycle.

[0098] Other structures can also be used without departing from the invention.

[0099] Thus, there are two methods of adjusting the indicator member 110 for the period in the annual cycle: one is to adjust the 31 -position drive wheel 55 step by step by means of the calendar adjustment member 250, and the other method is faster, by rotating the upper stem 410 in the intended direction of rotation.

[0100] The timepiece mechanism 1 according to the invention has several advantages. Since the display mechanism 110 for the period in the annual cycle is matched to the calendar mechanism 50, the display of the period in the annual cycle will never be behind and will always be matched to the calendar, if the calendar mechanism is kept up to date, for example by making the relevant adjustments during short months.

[0101] Thus, this mechanism is particularly precise compared to a display mechanism for the period in the annual cycle which is not connected to a calendar or to a calendar drive wheel having 31 stable positions.
