AI Technical Summary
Existing watch mechanisms with a three-position control stem struggle to stabilize the intermediate position, leading to difficulties in adjusting additional functions like calendars or second time zones, and pose challenges in incorporating more functions without increasing stem travel or complicating the interface.
A clockwork mechanism with a single interface element, such as a control rod, that can be actuated in rotation and translation to reach three stable axial positions, allowing for four distinct configurations of function selection through a synergy of pull rods and indexing devices.
Enables intuitive and reliable selection of watch functions with a single interface, allowing for four configurations without increasing stem travel, thus simplifying the adjustment of complex functions like calendars and time zones.
Description
[0001] The invention relates to a watch mechanism comprising a device for selecting watch functions, as claimed in the appended set of claims. The invention also relates to a watch movement comprising such a mechanism. The invention further relates to a timepiece comprising such a movement or mechanism. The invention finally relates to a method for operating such a timepiece or such a movement or mechanism.
[0002] A mechanism with a three-position control stem is generally provided to allow the adjustment of a timepiece including an additional function, such as a calendar or a second time zone, which needs to be adjusted.
[0003] Position "2" or the intermediate position of the stem is not always easy to reach by the user of a timepiece, in particular a watch, and there is a risk that this stem passes directly from the first (position "1") to the last position (position "3") without it being able to be positioned stably at the intermediate position (position "2") due in particular to the axial forces required for its actuation. With such a risk, it is then understood that it would be difficult to add yet another intermediate stem position dedicated to the adjustment of another additional function. All the more so since with a fourth stem position, the travel of the stem would have to be increased, which would pose difficulties in terms of space requirements, both at the level of the movement and at the level of the watch crown.To address this, one solution would be to reduce the travel between the axial positions of the rod, but this would make function selection even more difficult.
[0004] Therefore, watches equipped, for example, with a time zone, a moon phase or an annual, semi-perpetual or perpetual calendar, generally have at least one additional interface means in addition to the control stem to be able to select and adjust several additional functions. This additional interface means can, for example, be in the form of a pusher, or a selection bezel.
[0005] The proliferation of interface methods risks complicating the adjustment of the timepiece. It also implies design constraints, due to the very fact that they must be included within the watch.
[0006] Document EP2453322 describes a chronograph movement equipped with a mechanism comprising a stem having three stable axial positions. The particularity of this mechanism lies in the fact that it offers the possibility of setting an additional function derived from the time by actuating one of the chronograph pushers when the control stem is not in a first position. More particularly, when the stem of the mechanism is in the first position, the pusher allows interaction with the chronograph, whereas when the stem is in another position, the pusher allows setting an additional function derived from the time.
[0007] Document EP1939699 discloses a mechanism having a particular arrangement of a crown intended for the selection and adjustment of different functions. Unlike a mechanism provided with a conventional interface implementing a control stem, a rotation of this crown allows the selection of the function to be adjusted, and a pressure on it allows the adjustment of the previously selected function. The adjustment is therefore done incrementally, as is possible with a simple corrector.
[0008] Document CH702803 describes a mechanism comprising a rod having three stable axial positions and further comprising a crown and a pusher preferably coaxial. According to one of the axial positions of the rod, the rotation of the crown allows the selection of an adjustment function, and the actuation of the pusher allows an incremental adjustment of the previously selected function.
[0009] Document CH702548 describes a mechanism for selecting three configurations of a selection device; winding the movement according to a first configuration, setting a time zone according to a second configuration, and setting the time according to a third configuration. The configuration of this mechanism is selected by pressing a crown, like a pusher. Rotating the crown allows winding or setting the previously selected function.
[0010] Document WO2013030268A1 describes a time display device comprising a time display member and a switching mechanism enabling the time display member to switch between a first time zone and a second time zone. This switching mechanism comprises a two-position selection member and a control member for selecting the first or second time zone to be displayed.
[0011] The documents identified in this state of the art highlight alternative solutions to mechanisms conventionally equipped with a single control stem. Although some of these solutions allow more functions to be set than a three-position control stem allows, they all have the disadvantage of requiring a second interface means such as a pusher, coaxial or not with the crown, and / or a sequential selection of the different functions. Such mechanisms, which implement a sequential selection of the different functions, may also require an additional display means in order to allow the user to be aware of the selected function, which may impact the aesthetics of the timepiece.Furthermore, even if the use of a push-button designed to allow the adjustment of an additional function of the movement is known and very widely used, its arrangement is not easy, both in terms of size and the water resistance of the watch. In addition, the implementation of a push-button implies that the adjustment is done incrementally, which is not suitable for certain functions such as, for example, the manual winding of a movement or setting the time.
[0012] Document US2019163139A1 describes a mechanism in which, when the winding stem is in its second position, it cooperates with a cam wheel which allows the selection of one of three different functions.
[0013] Document US3890778A describes means arranged to selectively connect a rod in an intermediate position with a first indicator element in response to extraction of the rod from the depressed position to the intermediate position and with a second indicator element in response to depression of the rod from the depressed position to the intermediate position.
[0014] The aim of the invention is to provide a device for selecting watch functions that makes it possible to improve the devices for selecting watch functions known from the prior art. In particular, the invention proposes a particularly reliable and easy-to-use device for selecting watch functions, which makes it possible to obtain at least four configurations for selecting watch functions.

[0022] A first embodiment of a timepiece 1000 is described below with reference to figures 1 to 14 .
[0023] The timepiece 1000 is for example a watch, in particular a wristwatch.
[0024] The 1000 timepiece includes a 900 watch movement intended to be mounted in a timepiece case or box to protect it from the external environment.
[0025] The 900 watch movement can be an electronic movement or a mechanical movement, including an automatic movement. The 900 watch movement includes an 800 watch mechanism.
[0026] The timepiece 1000, in particular the watch movement 900, in particular the watch mechanism 800, comprises a device 200 for selecting watch functions. The timepiece 1000, in particular the watch movement 900, in particular the watch mechanism 800, preferably further comprises: a 300 winding drive train, a first 400 adjustment drive train, and a second 500 adjustment drive train.
[0027] Thanks to the solutions described, it is possible to configure the function selection device 200 according to four distinct configurations with a single interface element 1 appearing, for example, in the form of a control stem which can be positioned according to three stable axial positions. In the variant of the first embodiment of timepiece 1000 illustrated by the figures 1 to 14 , this single interface element is in the form of a control rod 1. This rod can be actuated in rotation and in translation along an axis A1. The translation of this control rod 1 makes it possible to reach three stable axial positions, namely a first extreme position P1, a second intermediate position P2 and a third and last extreme position P3.
[0028] Within a mechanism provided with a conventional control rod, each axial position of the rod makes it possible to conform a function selection device, in particular a pull rod, according to a given configuration. The function selection device 200 which is the subject of this document has the specific feature of comprising a number of configurations greater than the number of axial positions of the control rod. This is for example made possible by the fact that such a selection device 200 has the specific feature of comprising a pull rod device 150 provided with two pull rods or rockers, and that it is capable of being indexed in position either by a first indexing device 4 or by a second indexing device 5.More particularly, the different configurations of the selection device are determined by the synergy of the two pulls or rockers, and the axial positions of the rod 1 are determined by one or the other of the two indexing devices. As described below, this means that, in the same embodiment of a selection device, the interface element 1 is, in certain configurations of the selection device, indexed in position by the first indexing device and, in other configurations of the selection device, indexed in position by the second indexing device. In other words, in certain configurations of the selection device, a stable position of the interface element 1 is determined by the first position indexing device and, in other configurations of the selection device, another stable position of the interface element 1 is determined by the second position indexing device.
[0029] According to the invention as claimed, the device 200 for selecting watch functions comprises: a pull device 150, and a frame 100.
[0030] More particularly, the pull device 150 comprises a rocker 2, in particular a first pull 2, mounted movably on the frame 100 and a rocker 3, in particular a second pull 3, mounted movably on the rocker 2 or on the frame 100. The selection device 200 further comprises: the first position indexing device 4 arranged so as to act on the rocker 2, and the second position indexing device 5 arranged so as to act on the rocker 3.
[0031] According to the invention as claimed, the device 200 for selecting watch functions may comprise the interface element 1, in particular the control stem 1, and the pull device 150 may be arranged so as to define: n stable positions of the interface element 1, with n ≥ 3, and m selection configurations of the selection device 200, with m≥n+1.
[0032] In the first embodiment of the timepiece 1000, the lever 2 can be likened to a first pull 2, and the lever 3 can be likened to a second pull 3.
[0033] The first pull rod 2 is mounted pivoted relative to the frame 100 around an axis A2. Preferably, the second pull rod 3 is mounted pivoted relative to the frame 100 around this same axis A2. The axis A2 is for example perpendicular to a main plane P along which the frame 100 of the movement mainly extends.
[0034] The selection of the different functions of the 800 watch mechanism is made possible thanks to the first pull 2 and the second pull 3, which are more particularly visible on the Figure 3, and the selection device 200 can be shaped respectively according to four distinct configurations C1, C2, C3 and C4 defined by three axial positions P1, P2 and P3 of the interface element 1.
[0035] To move from one position to another, the interface element 1, in particular the control rod 1, can be pulled along the axis A1, perpendicular to the axis A2, in a first direction D1 called “traction”, and pushed or pressed along this same axis A1 in a second direction D2 called “compression”.
[0036] The rotation of the first pull rod 2 is directly controlled by the translation of the interface element 1. To do this, the first pull rod 2 comprises a first stud 21, which is housed within a first groove 1a of the interface element 1. The elements 1a and 21 thus form an articulation connecting the interface element 1 and the first pull rod 2.
[0037] The angular position of the pull tab 2 is defined by the first position indexing device 4. This first indexing device 4 preferably comprises a first spring 41 provided with a first functional surface 42 (forming in particular a double beak), as well as a second pull tab stud 22, arranged on the first pull tab 2 as shown in particular in the Figure 6 The cooperation of the first functional surface 42 with the second pad 22 makes it possible to define angular indexing positions of the pull tab 2. In particular, this cooperation makes it possible to define two stable angular positions of the first pull tab 2, as well as a third unstable position of the first pull tab 2. By extension, this cooperation also makes it possible to define two stable axial positions of the interface element 1, as well as a third unstable axial position of the interface element 1.
[0038] The second pull rod 3 is, for its part, linked to a control wheel 7 by means of a gear connection 33, 71. To do this, the second pull rod 3 comprises a fourth toothing 33 meshing with a fifth toothing 71 of the control wheel 7. The angular positioning of the second pull rod 3 is ensured by the second indexing device 5. The latter preferably comprises a second spring 51 provided with a second functional surface 52 (forming for example a beak), as well as the control wheel 7 provided with a third functional surface 72 (forming for example star teeth, as illustrated in the figures 4 And 5). More particularly, the cooperation of the second functional surface 52 with the third functional surface 72 makes it possible to define three stable angular positions of the second pull rod 3. Furthermore, in a given configuration of the selection device 200, the second pull rod 3 also contributes to the stable axial positioning of the interface element 1.
[0039] The control mobile 7 is advantageously pivoted on the frame 100, in particular pivoted perpendicular to the plane P of the frame 100.
[0040] When moving from a first given stable position to a second given stable position of the interface element 1, the first pull rod 2 can drive the second pull rod 3 thanks to a third stud 23 of the first pull rod 2, which is capable of cooperating with a latching member 6, pivoted on the second pull rod 3, through an oblong cutout 31 of the second pull rod 3.
[0041] This cooperation is however a function of the prior position of the interface element 1 and the actuation it undergoes. To do this, a fifth return spring 62 tends to maintain the latching member 6, in particular its beak 61, on the path of the third stud 23, while a cutout 99 formed on the frame 100 makes it possible to control said beak 61 so that it can or cannot find itself on the path of the third stud 23. The latching member 6 is for example a lever provided with a beak. More particularly, the latching member 6 comprises a fourth stud 63 intended to cooperate with the profile formed by the periphery of the cutout 99. The respective conformations of this profile and of the fourth stud 63 make it possible to control the position of the latching member 6 as a function of the angular position of the second pull rod 3 relative to the frame 100.In other words, depending on the angular position of the second pull tab 3, the latching member 6, more particularly its beak 61, may or may not be on the path of the third stud 23.
[0042] Furthermore, this third stud 23 of the first pull tab 2 is also capable of cooperating with the oblong cutout 31 of the second pull tab 3.
[0043] Thus, the selection device 200, in particular the pull-tab device 150, comprises a latching member 6 arranged so as to secure the pull-tab 2 and the rocker 3 in certain operating configurations. The position of this latching member 6 is controlled at least partially by the profile formed by the periphery of the cutout 99 as a function of the position of the pull-tab 2 and / or the pull-tab 3. More particularly, the latching member 6 is capable of cooperating with the profile formed by the cutout 99 of the frame 100 so that it is capable, according to at least one configuration of the function selection device 200, of locking any relative movement between the first and second pull-tabs 2, 3.
[0044] Ultimately, the relative position of the two pulls 2 and 3, as well as their relative position with respect to the frame 100, advantageously make it possible to select four distinct configurations allowing the actuation of four different functions of the watch movement 900. The details of the sequencing of the different positions of the interface element 1 and the configurations of the selection device 200 will be explained below.
[0045] Advantageously, the pull device 150, the first position indexing device 4 and the second position indexing device 5 are arranged so that a stable position of the interface element 1 is determined: either by the first position indexing device 4, or by the second position indexing device 5.
[0046] Advantageously, the pull device 150 is arranged so as to define at least two distinct selection configurations of the selection device 200 for the same stable position P2, or intermediate position, of the interface element 1, in particular the same stable position P2 of the interface element 1 between two extreme stable positions P1 and P3 of the interface element 1. Preferably, the second and third configurations are selectable following a back-and-forth movement of the interface element 1 from the position P2 of said interface element 1.
[0047] These three positions P1, P2 and P3 of the interface element 1 make it possible to configure the function selection device 200 according to four distinct configurations. These four configurations allow the activation of different winding and adjustment chains of the watch mechanism 800 in order to allow the user to be able to activate the different functions of the watch movement 900. In particular: a first configuration C1 allows the manual winding of the watch by means of a kinematic winding chain 300, a second configuration C2 allows the adjustment, in particular the bidirectional adjustment, of the date indication by a first conformation of a first adjustment chain 400, a third configuration C3 allows the adjustment, in particular the monodirectional adjustment, of the indication of the days of the week by a second conformation of the first adjustment chain 400, a fourth and last configuration C4 allows the time setting of the movement by a second adjustment chain 500.
[0048] Advantageously, the selection device 200 allows easy and intuitive selection of the different watch functions: the first configuration C1 being defined by the first position P1 which happens to be the extreme position of the interface element 1 obtained by action in the second direction D2 of actuation of the interface element 1, the second configuration C2 being defined by the second position P2 and being able to be selected only after traction of the interface element 1 in the first direction D1 from the first position P1, the third configuration C3 also being defined by the second position P2 of the interface element 1, after the latter has made a back-and-forth movement, from the second position P2 and returning to the second position P2, having transiently passed through the third position P3 or around the third position P3. In this transient state, the position P3 is unstable.The return backward of the interface element 1 from the third position P3 or its surroundings advantageously makes it possible to discriminate between the second and third configurations of the selection device, the fourth configuration C4 being defined, for its part, by the third position P3 of the interface element 1 which happens to be the extreme position of the interface element 1 obtained by action in the first direction D1 of actuation of the interface element 1. As it is essential to select the third configuration C3 beforehand to select this last configuration, it cannot be confused with the second configuration C2.
[0049] It is therefore possible to discriminate, by the kinematics of the interface element 1, all the configurations of the function selection device 200.
[0050] The first extreme position P1 of the interface element 1, stable and the most deeply embedded in the frame 100, makes it possible to define a first configuration C1 of the selection device which allows actuation of the manual winding chain of the watch movement 900.
[0051] The second intermediate stable position P2 of the interface element 1 makes it possible to define: a second configuration C2 of the function selection device which allows actuation of a first unidirectional or bidirectional adjustment chain of a function for indicating a first information derived from the time, and a third configuration C3 of the function selection device which allows actuation of a second unidirectional or bidirectional adjustment chain of a function for indicating a second information derived from the time.
[0052] For example, the first adjustment chain is an adjustment chain (in particular bidirectional adjustment) of a date indication and the second adjustment chain is an adjustment chain (in particular unidirectional adjustment) of a day indication.
[0053] For example, the first adjustment chain could be an adjustment chain (in particular bidirectional adjustment) of a time zone indication and the second adjustment chain could be an adjustment chain (in particular unidirectional adjustment) of a date indication.
[0054] Finally, the third extreme position P3 of the interface element 1, stable and the most removed from the frame 100, makes it possible to define a fourth configuration C4 of the selection device which allows actuation of a time adjustment chain.
[0055] The detail of the mechanism 800 is explained below by means of the variant of the first embodiment of the timepiece 1000 illustrated by the figures 1 to 14 .
[0056] There Figure 2illustrates a part of the winding kinematic chain 300 made operational thanks to the first configuration C1 of the function selection device 200, when the control stem 1 is located in the first position P1. This winding kinematic chain 300 here comprises a vertical clutch device comprising a first crown wheel 301 meshing with a winding pinion 10 mounted square on the control stem 1. This first crown wheel 301 is also capable of meshing with a second crown wheel 302 depending on the state of the vertical clutch device, controlled by the axial position of the control stem 1 along the axis A1. A sliding axis 303, integral with the second crown wheel 302, is located at the bottom of a second groove 1b of the control stem 1 thanks to the support of a return spring 304.The first wheel 301 and the second control wheel 302 are then engaged with each other, thus allowing manual winding of the movement. When the control stem 1 is in the other positions P2 and P3, the sliding shaft 303 is outside the second groove 1b, thus disengaging the second crown wheel 302 from the first crown wheel 301. Such a vertical clutch device is for example described in document WO2012175595.
[0057] The first adjustment chain 400 is capable of being engaged by a first toothing 11a of a sliding pinion 11 mounted square on the control rod 1. More precisely, when the control rod 1 is in the second position P2, the sliding pinion 11 is placed by a rocker 12 pivoted on the frame 100 and controlled by the control wheel set 7 so that the toothing 11a of the sliding pinion 11 can mesh with a third front toothing 401a of a first pinion 401 of the first adjustment chain 400. This first pinion is designed to drive a corrector wheel 404 via a wheel 403. This corrector wheel 404 has the particularity of being pivoted on a lever 402 controlled by a lever 14 of the clockwork mechanism 800. The corrector wheel 404 is pivoted around a fixed axis relative to the lever 402.
[0058] As illustrated in particular on the Figure 4, the control mobile 7, which includes a control cam, comprises a third profile 73 and a fourth profile 74 capable of cooperating with the rockers 12, 14 respectively. A return spring 13 and a return spring 15 tend respectively to return these rockers 12, 14 towards these third and fourth profiles 73, 74 of the control mobile 7 with which they are capable of cooperating.
[0059] When the device 200 is configured according to the second configuration C2 or according to the third configuration C3, the third profile 73 of the mobile 7 makes it possible to release the lever 12 under the effect of the spring 13, in order to allow the sliding pinion 11 to engage the first adjustment chain 400.
[0060] When the device 200 is configured according to the second configuration C2 or according to the third configuration C3, the fourth profile 74 of the mobile 7 makes it possible to control the rocker 14 in cooperation with the spring 15, in order to allow the positioning of the rocker 402. The cooperation of the rocker 14 and the rocker 402 is carried out here in particular by means of a first pin 14a of the rocker 14, which cooperates by contact with a cam profile 402a of the rocker 402.
[0061] The 800 clockwork mechanism for correcting one or more clockwork functions thus comprises: the correcting mobile 404, the flip-flop 14 including a first desmodromic cam connection element 14a, and the flip-flop 402.
[0062] The 402 flip-flop has the particularity of including: at least one first element 402d for guiding the corrective wheel 404, at least one first element 402b for friction against the corrective wheel 404, a second desmodromic cam connection element 402a provided to cooperate by contact with the first desmodromic cam connection element 14a.
[0063] The rocker 402 is in particular pivoted relative to the frame 100 on an axis 402e or a rotational guide element 402e. The rocker preferably comprises two branches connected to each other at the level of the rotational guide element 402e: a first branch having, at one end, the rotational guide element 402e and, at the other end, the at least one first element 402d for guiding the corrective wheel set 404 and the at least one first element 402b for friction against the corrective wheel set 404, a second branch having, at one end, the rotational guide element 402e and, at the other end, the second desmodromic cam connection element 402a.
[0064] By the action of the desmodromic cam linkage, the position of flip-flop 14 determines the position or configuration of flip-flop 402.
[0065] Thus, the flip-flop 14 and the flip-flop 402 are configured and / or arranged so as to position the flip-flop 402 according to a first angular position and a second angular position around its axis 402e, the first angular position making it possible to activate a first correction function, in particular a date indication correction function, and the second angular position making it possible to deactivate the first correction function.
[0066] Advantageously, the flip-flop 14 and the flip-flop 402 are configured and / or arranged so as to position the flip-flop 402 in a third angular position around its axis 402e, making it possible to activate a second correction function, in particular a function for correcting the indication of the days.
[0067] Preferably, the flip-flop 14 and the flip-flop 402 are configured and / or arranged such that, in the second angular position, the second correction function is deactivated.
[0068] In the variant shown on the figures 1 to 14 of the first embodiment, the first desmodromic cam link member is a stud 14a or a pin and the second desmodromic cam link member is a cam profile 402a. Alternatively, in another variation, the first desmodromic cam link member could be a cam profile and the second desmodromic cam link member could be a stud or a pin.
[0069] In particular, the corrector wheel 404 comprises a corrector 406 for indicating the dates, as well as a toothed wheel 405 integral in rotation with the corrector 406. The cooperation of the elements 14 and 74 makes it possible to position the corrector 406 of the corrector wheel 404 in the teeth of a date disc 600 (as shown in the Figure 7) or to position the toothed wheel 405 of the corrector wheel 404 in the teeth of a star 700 of the day display (as shown in the Figure 11 ) or to disengage the corrector mobile 404 from any adjustment function (as shown in the figures 5 , 9 And 13 ).
[0070] Preferably, the rocker 402 comprises at least one arm 402c and the first friction element 402b comprises at least one friction surface 402f, the at least one arm 402c being arranged so as to elastically return the at least one friction surface 402f against the corrective mobile 404.
[0071] In the particular variant of rocker 402 illustrated in particular by the Figure 5, this is more specifically provided with two elastically deformable arms 402c each comprising two bearing surfaces 402f cooperating by contact with the portion 404a of the corrective wheel set preferably having a cylindrical shape. In this particular variant of rocker 402, the friction element 402b is thus implemented by means of two elastically deformable arms each comprising two bearing surfaces 402f cooperating by contact with the portion 404a of the corrective wheel set. Thus shaped, the friction element 402b applies at least one radial or substantially radial force (with the effects of the friction coefficient close) on the portion 404a of the corrective wheel set.
[0072] In this particular variant of rocker 402, the four bearing surfaces 402f define a housing allowing the engagement of the portion 404a of the corrective wheel set within the rocker 402. Preferably, the bearing surfaces 402f are equally distributed around the portion 404a of the corrective wheel set 404, that is to say that the angular interval between any neighboring bearing surfaces is identical or substantially identical.
[0073] In this particular variant of rocker 402, the element 402d for guiding the rotation of the correcting wheel 404 is implemented by the bearing surfaces 402f cooperating by contact with the portion 404a of the correcting wheel. In this particular case, the element 402d for guiding the rotation of the correcting wheel 404 and the friction element 402b are thus merged or formed by the same element.
[0074] Preferably, the rocker 402 is a single piece. The rocker 402 can for example be obtained by cutting from a plate or by electroforming techniques such as LIGA.
[0075] Advantageously, the flip-flop 402 can comprise a single level, that is to say that its functions: for guiding the rotation of the corrective mobile, and for controlling its position by contact with the rocker 14, are provided on the same level or at the level of the same plane constituting a main plane of the scale along which the scale mainly extends, or have a plane in common.
[0076] Accordingly, the thickness of the scale 402 or the thickness footprint of the scale may be reduced. The thickness or thickness footprint may be less than 200 µm or less than 150 µm.
[0077] The friction torque generated by the friction element 402b acting on the portion 404a of the corrective wheel set allows the lever 402 and its corrective wheel set to pivot around the rotational guiding element 402e of the lever 402, and this depending on the direction of rotation of the adjustment chain 400. Thus, each reversal of direction of rotation applied to the adjustment chain is likely to generate a rotation of the lever 402 under the effect of the rotation of the corrective wheel set.
[0078] This rocker 402 here has the particularity of comprising the profile 402a, in the form of a groove, which is intended to cooperate with the stud 14a of the rocker 14. Advantageously, the groove 402a is provided with three distinct portions 1402a, 2402a, 3402a. The cooperation between the elements 14a and 402a makes it possible to define at least three angular positions of the rocker 402 around the guide element 402e.
[0079] More particularly, when the function selection device 200 is in the second configuration C2, the pad 14a makes it possible to lock the angular position of the lever 402 so that the correcting wheel set 404 can perform a bidirectional adjustment of the date indication (as visible on the Figure 7). In this second configuration, the stud 14a of the rocker 14 is located at the level of the first portion 1402a of groove 402a. This first portion comprises two parallel or substantially parallel flanks arranged on either side of the stud 14a, which prevent any untimely rotation of the rocker 402 around its axis 402e with the clearance between the stud and the flanks, the distance between the two flanks corresponding to the diameter of the stud with the clearance. Each of these flanks forms an angle of the order of 90° opposite a segment defined by a first point passing through the pivot axis A14 of the rocker 14 and a second point passing through the center of the stud 14a. In other words, the flanks are arranged orthoradially or substantially orthoradially with respect to the axis A14. Each of these sides also forms a non-zero angle (for example approximately 90°) with the orthoradial direction at the 402e axis.Such a conformation prevents any untimely rotation of the rocker 402 around the axis 402e under the effect of the elements 402b, 402c, 402d potentially actuated by a rotation of the mobiles 401, 403, 404 around their respective axis. In this second configuration C2, the rocker 14, under the effect of its return spring 15, is positioned in a hollow formed within the profile 74 of the control mobile 7 connected to the second pull rod 3.
[0080] When the function selection device 200 is in the third configuration C3, the pad 14a makes it possible to position the rocker 402 while giving it a degree of freedom in rotation so as to allow the correcting wheel set 404 to carry out a one-way adjustment of the day indication (as visible on the Figure 11). In this third configuration C3, the stud 14a is arranged within a third portion 3402a of groove 402a. This third portion 3402a comprises flanks shaped and oriented in such a way that the latter allow a rotation of the lever 402 around the axis 402e over a given angular range, so that the latter is capable of reaching an angular position allowing the wheel 405 to mesh with the day indicator wheel 700 under the effect of the elements 402b, 402c, 402d potentially actuated by a rotation of the mobiles 401, 403, 404 around their respective axes. More particularly, the distance between two flanks of the third portion 3402a, in a direction orthoradial to the axis 402e, is greater than the diameter of the stud 14a. For example, this distance is of the order of three times the diameter of plot 14a.
[0081] In the other configurations C1 and C4, the position of the rocker 402, still defined by the pad 14a, is such that the corrector wheel 404 is out of range of the date or day indicators (as visible on the figures 5 , 13 ). In these configurations C1 and C4, the stud 14a of the rocker 14 is located at the level of the second portion 2402a of groove 402a. This second portion comprises two parallel or substantially parallel flanks arranged on either side of the stud 14a, which prevent any untimely rotation of the rocker 402 around its axis 402e, excluding the clearance between the stud and the flanks, the distance between the two flanks corresponding to the diameter of the stud excluding the clearance. Each of these flanks forms an angle of the order of 45° with respect to a segment defined by a first point passing through the axis A14 and a second point passing through the center of the stud 14a. Each of these flanks also forms a non-zero angle with the direction orthoradial to the axis 402e.
[0082] In the first configuration C1, the rocker 14 has the particularity of being held in position against its return spring 15 by the pull rod 2, in particular by the profile 24 of the pull rod 2, the latter being positioned by the control rod 1, itself positioned according to the first axial position P1.
[0083] In the fourth configuration C4, the lever 14 is positioned against its spring 15 by the profile 74 of the mobile 7, the latter being positioned by the control stem 1, itself positioned according to the third axial position P3. In this fourth configuration, the second adjustment chain 500 allows the time to be set on the movement. More particularly, the function selection device 200 conforms the watch mechanism 800 so that a second front toothing 11b of the sliding pinion 11 meshes with a second pinion 501 of the second chain 500, thus allowing the user to be able to set the time on the movement.More particularly, in this configuration, the profile 73 of the mobile 7 makes it possible to position the lever 12 in such a way that a second front toothing 11b of the sliding pinion 11 meshes with a second pinion 501 of the second chain 500, thus allowing the user to be able to set the time of the movement.
[0084] The details of the sequencing of the different positions of the interface element 1, in particular of the control stem 1, and of the configurations of the selection device 200 are explained below by means of the variant of the first embodiment of the timepiece 1000 illustrated by the figures 1 to 14 .
[0085] The first configuration C1 of the function selection device 200, illustrated by the Figures 5 and 6, defines the winding configuration of the movement 900. The control stem 1 is in the first position P1, which activates or makes operational the winding kinematic chain 300, and it is held in this position by the first indexing device 4. More particularly, the second stud 22 of the first pull 2 is held in position by the first flank 42a of the first functional surface 42 of the first spring 41.
[0086] The second pull tab 3 is, for its part, held in position by the second indexing device 5. More particularly, it is held in position by the second functional surface 52 which cooperates here with a first indexing notch 72a of the third functional surface 72 of the mobile 7.
[0087] In this first configuration, the latching member 6 is clear of the path of the third stud 23. More particularly, the respective conformations of the fourth stud 63 and of the profile of the cutout 99 of the frame 100 make it possible to keep the beak 61 out of reach of the third stud 23.
[0088] In this first configuration, the rockers 12 and 14, due to the arrangement of the control rod 1 and the first pull rod 2, are here out of reach of the third and fourth profiles 73, 74 of the control mobile 7.
[0089] More particularly, the sliding pinion 11 is here recalled by the lever 12 against a bearing surface of the control stem 1 so that it is disengaged from any adjustment chain, while the lever 14 is held in position by the first pull rod 2 by means of a second profile 24. In this configuration, the lever 402 is positioned by the lever 14 so that the corrector wheel set 404 is out of range of the date disc and the day display star. Transition from the first configuration C1 to the second configuration C2:
[0090] To configure the function selection device 200 according to the second configuration C2 illustrated by the figures 7 and 8, it is necessary to pull the control rod 1 in the first direction D1, from the first position P1 to the second position P2. During this action, the third stud 23 of the first pull rod 2 freely travels the oblong cutout 31 of the second pull rod 3 without driving the latter. The control rod 1 and the first pull rod 2 are then indexed by a hollow formed by a second flank 42b of the first spring 41 cooperating with the second stud 22 of the first pull rod 2. According to this second configuration C2, the position of the second pull rod 3 remains unchanged compared to the first configuration C1.
[0091] The control mobile 7 and the latching member 6 have remained stationary, and the latter remains out of range of the trajectory of the third stud 23.
[0092] The axial movement of the control rod 1 in the first direction D1 causes the disengagement of the winding kinematic chain 300, and the engagement of the first adjustment chain 400. The movement of the rocker 12, under the effect of the spring 13, is possible here, because the third profile 73 is here shaped in such a way as to allow it this degree of freedom.
[0093] In this configuration, the lever 14 is no longer retained by the second profile 24 of the first pull-out piece 2, which allows it to position the lever 402 in a stable angular position around the axis 402e, which is characterized by the fact that the corrector 406 is arranged in the toothing of the date disc 600, in particular at the level of its primitive diameter. As for the lever 12, the movement of the lever 14 is possible here because the profile 74 is shaped so as to allow it this degree of freedom.
[0094] More particularly, in this second configuration, the toothing 11a of the sliding pinion 11 meshes with the front toothing 401a of the pinion 401 of the first adjustment chain 400. This first pinion drives the correcting wheel set 404 via the wheel set 403 pivoted around the axis 402e. Transition from the second configuration C2 to the third configuration C3:
[0095] By pulling the control rod 1 again, the latter temporarily reaches the third position P3 before returning to the second position P2, under the effect of the first spring 41, after the control rod 1 is released by the user.
[0096] The transient, unstable state in which the control rod 1 is temporarily in the third position P3 is illustrated by the figures 9 and 10 This unstable position of the control rod 1 makes it possible to configure the function selection device 200 so as to allow one-way adjustment of the day indication.
[0097] In the pulling action of the control rod 1 towards the third position P3, the first pull rod 2 drives the second pull rod 3 which then drives the control wheel 7. This is made possible thanks to the third stud 23 of the first pull rod 2 which acts against a first end of the oblong cutout 31 of the second pull rod 3, the latter already being arranged at this first end according to the second configuration C2.
[0098] At the end of its rotational movement, the second pull tab 3 is held in its new position by means of the second indexing device 5. More particularly, the second pull tab 3 is held in its new position by the second functional surface 52 cooperating here with a second indexing notch 72b of the third functional surface 72 of the mobile 7, the latter being connected to the second pull tab 3 by means of the gear connection 33, 71.
[0099] Thus, while the control rod 1 is in an unstable position, the second pull rod 3 is in a stable position defined by the second indexing device 5.
[0100] In this new stable position of second pull tab 3, the profile of the cutout 99 formed in the frame 100 allows the latching member 6 to be released. Thus, under the effect of the fifth return spring 62, the latching member 6 is on the trajectory of the third stud 23. More precisely, a fourth flank 61a of the beak 61 is now in contact with the third stud 23.
[0101] Like the control rod 1, the first pull rod 2 is also in an unstable position, the position of the latter not being defined by the first indexing device 4. More particularly, the second stud 22 of the first pull rod 2 is located on a third flank 42c of the first spring 41, which tends to return the control rod 1 to the second position P2, in the hollow of the second flank 42b, after the user has released the control rod 1. After this last action, the function selection device 200 is then configured according to the third configuration C3. This configuration is illustrated by the Figures 11 and 12 .
[0102] When the control rod 1 returns to the second position P2, the third stud 23 of the first pull rod 2 then pushes back the fourth flank 61a of the beak 61 of the latching member 6. This latching member 6 can thus fold back and allow the third stud 23 to pass on the other side of the beak 61. The stud 23 is thus locked between a fifth flank 61b of the beak 61 and a second end of the oblong cutout 31. The first and second pull rods are then secured in rotation. Any relative rotational movement between the first and second pull rods is therefore impossible.
[0103] In this third configuration C3, the first and second pull rods are thus indexed in a stable position by the second indexing device 5. By extension, the control rod 1 is also indexed in a stable position by the second indexing device 5.
[0104] In this third configuration C3, the rocker 12 here retains its position as defined by the second configuration C2, which allows the sliding pinion 11 to remain engaged with the first adjustment chain 400.
[0105] On the other hand, the profile 74 of the control wheel 7 actuates the lever 14 so that the latter configures the lever 402 so as to allow the adjustment of the days. In particular, this allows the wheel 405 of the corrector wheel 404 to carry out a one-way adjustment of the indication of the days by meshing with the teeth of the wheel 700 of the days.
[0106] Thus, in this third configuration, the sliding pinion 11, the first pinion 401, the mobile 403 and the correcting mobile 404 remain meshed. Only the position of the lever 14 is modified under the effect of the rotation of the control mobile 7, which is controlled by a back-and-forth movement of the control rod 1 allowing the mechanism to pass from the second configuration C2 to the third configuration C3. More particularly, in this third configuration, the lever 14 is positioned by a projection formed at the profile 74 of the control mobile 7. Transition from the third configuration C3 to the fourth configuration C4:
[0107] A further pull on the control rod 1 in the first direction D1 allows the control rod 1 to reach the third stable position P3, and sets the function selection device 200 according to the fourth configuration C4. This configuration is illustrated by the Figures 13 and 14 .
[0108] When the control rod 1 moves from positions P2 to P3, the first pull rod 2 pulls the second pull rod 3 with it, the latter being rotationally fixed by means of the elements 23, 31 and 6.
[0109] The second pull tab 3 is then held in a new stable position by the second indexing device 5. More particularly, the second functional surface 52 cooperates here with a third indexing notch 72c of the third functional surface 72 of the mobile 7.
[0110] By extension, the first pull tab 2 is also held in a stable position by means of the second indexing device 5, while the second pull tab stud 22 is still located on the third flank 42c of the first spring 41.
[0111] In this fourth configuration, the rocker 12 is actuated by the profile 73 so that the sliding pinion 11 can engage the second adjustment chain 500.
[0112] The lever 14 is actuated by the profile 74 so that the lever 402 is positioned so that the corrector wheel 404 is out of range of the teeth of the date disc and that of the star of the days of the week.
[0113] The movement can therefore be set to the correct time by the user.
[0114] The fourth configuration C4 is distinguished from the first configuration by the fact that the rocker 14 is held in position not by the profile 24 of the pull rod 2, but by a profile 74 of the control mobile 7 kinematically linked to the second pull rod 3, the latter being previously positioned by the control rod 1, itself positioned according to the third axial position P3 by means of the first pull rod 2. Transition from the second configuration C2 to the first configuration C1 :
[0115] From the second configuration C2, by pushing the control rod 1 in the second direction D2 from the position P2 to the position P1, the first pull rod 2 is simply reconfigured according to the first configuration C1. More particularly, the second pull rod pad 22 passes from the second flank 42b to the first flank 42a of the first spring 41.
[0116] Returning the control rod 1 to position P1 allows the winding drive chain 300 to be re-engaged. Simultaneously, the control rod 1 also disengages the sliding pinion 11 of the first adjustment chain 400.
[0117] In this same action, the first pull 2 pushes back the lever 14, thus ensuring that the corrector wheel 404, pivoted on the lever 402, is out of reach of the teeth of the date disc and that of the day star. Transition from the third configuration C3 to the first configuration C1 :
[0118] From the third configuration C3, only the first configuration C1 can be selected when the control rod 1 is pushed from the second position P2 to the first position P1.
[0119] By pushing the control rod 1 in the second direction D2, the latter simultaneously drives the first and second pull rods 2, 3 so as to reconfigure the function selection device 200 according to the first configuration C1. This is made possible by the fact that, in the third configuration C3, the third stud 23 is in abutment in the oblong cutout 31.
[0120] It follows that the beak 61 of the latching member 6, which is located on the path of the third stud 23 in the third configuration C3, is again out of reach of the third stud 23 thanks to the cooperation of the fourth stud 63 with the profile of the cutout 99. Transition from the fourth configuration C4 to the first configuration C1:
[0121] From the fourth configuration C4, as from the third configuration C3, the second configuration C2 cannot be selected by pushing the control rod 1 in the second direction D2. Only the third and first configurations C3 and C1 can be reached by pushing the control rod 1.
[0122] In this fourth configuration C4, the relative position of the first and second pull rods 2, 3 is identical to that known from the third configuration C3. The kinematics of the pull rods 2, 3 when returning to the first configuration C1 from the fourth configuration C4 is therefore substantially identical to that known from the third configuration C3. The control rod 1 thus drives the first pull rod 2 which drives the second pull rod 3 thanks to the third stud 23 in contact with the oblong cutout 31.
[0123] In the same way, the beak 61 of the latching member 6 is released from the path of the third stud 23 thanks to the cooperation of the fourth stud 63 with the profile of the cutout 99.
[0124] A second embodiment of a 1000' timepiece is described below with reference to figures 15 to 21 .
[0125] Preferably, the second embodiment differs from the first embodiment only in part of its characteristics.
[0126] Thus, the references of elements of the second embodiment are deduced from those of elements of the first embodiment (having identical or substantially identical structures and / or identical or substantially identical functions) by the addition of an apostrophe “'”.
[0127] The 1000' timepiece is, for example, a watch, particularly a wristwatch.
[0128] The 1000' timepiece includes a 900' watch movement intended to be mounted in a timepiece case or box to protect it from the external environment.
[0129] The 900' watch movement can be an electronic movement or a mechanical movement, especially an automatic movement. The 900' watch movement includes an 800' watch mechanism.
[0130] The timepiece 1000', in particular the watch movement 900', in particular the watch mechanism 800', comprises a device 200' for selecting watch functions. The timepiece 1000', in particular the watch movement 900', in particular the watch mechanism 800', preferably further comprises: a winding drive train, a first adjustment drive train, and a second adjustment drive train.
[0131] The 200' watch function selection device mainly comprises: a 150' pull device, and a 100' frame.
[0132] Advantageously, the pull device 150' comprises a rocker 2', in particular a pull 2', mounted movably on the frame 100' and a rocker 3' mounted movably on the frame 100 or on the pull 2' and the selection device 200' further comprises: a first position indexing device 4' arranged so as to act on the pull 2', and a second position indexing device 5' arranged so as to act on the rocker 3'.
[0133] Alternatively or additionally, the device 200' for selecting watch functions may comprise an interface element 1, in particular a control stem 1, and the pull device 150' may be arranged so as to define: n stable positions of the interface element 1, with n ≥ 3, and m selection configurations of the selection device 200', with m≥n+1.
[0134] This second embodiment differs mainly from the first by the arrangement of the snap-in member as well as by the device for selecting the different winding and adjustment chains, which has the particularity of not including a control wheel.
[0135] Furthermore, the second embodiment differs from the first embodiment in that the second position indexing device 5' comprises a second spring 51' provided with a second functional surface 52' (forming a double beak) and a fifth stud 34' secured to the second pull rod 3'. The cooperation of the second functional surface 52' with the fifth stud 34' makes it possible to define the three stable angular positions of the second pull rod 3'.
[0136] Compared to the first embodiment, the snap-fastening member 6' of this second embodiment comprises a fourth functional surface 63' instead of a stud. This fourth functional surface is intended to cooperate with the profile formed by the periphery of the cutout 99' of the frame 100'. The kinematics of this snap-fastening member, as well as those of the components with which it is capable of cooperating, are identical to those known from the first embodiment.
[0137] The two levers 12', 14' of this second embodiment are not controlled by a control wheel. They are controlled directly by the first and second pull rods 2', 3'. However, the various winding and adjustment chains operate in a similar way to that known from the first embodiment.
[0138] Moreover, as for the first embodiment, a second profile 24', or more particularly here a sixth pad 24' is also capable of cooperating with the rocker 14'.
[0139] Furthermore, this second embodiment also has the particularity of having the second pad 22', the third pad 23' and the sixth pad 24' arranged coaxially.
[0140] As for the first embodiment, the function selection device 200' according to the second embodiment allows the selection of the different functions of the watch mechanism 800' using a first pull tab 2' and a second pull tab 3' (as shown in the figure 16 ) which can conform respectively according to four distinct configurations C1, C2, C3 and C4 defined by three axial positions P1, P2 and P3 of the control interface element 1.
[0141] Except for the aforementioned design differences between the two embodiments, the selection of the different configurations of this second embodiment is substantially identical or equivalent to that of the first embodiment. As a result, the entire description of the first embodiment describing the transitions from one configuration to another can be transposed to this second embodiment, regardless of the few aforementioned structural differences.
[0142] There Figure 17 illustrates the function selection device 200' according to the first configuration C1.
[0143] There figure 18 illustrates the function selection device 200' according to the second configuration C2.
[0144] There figure 19illustrates the transient, unstable state in which the control rod 1 of the function selection device 200' is temporarily in the third position P3, when changing from the second configuration C2 to the third configuration C3.
[0145] There figure 20 illustrates the 200' function selection device according to the third configuration C3.
[0146] There figure 21 illustrates the 200' function selection device according to the fourth configuration C4.
[0147] A method of executing a method of operating a device for selecting watch functions as mentioned above or a watch mechanism as mentioned above or a watch movement as mentioned above or a timepiece as mentioned above is described below.
[0148] The process includes the following steps: the selection device 200; 200' is configured according to the second configuration C2 when the interface element 1 is moved from the first stable position P1 to the second intermediate stable position P2, and the selection device 200; 200' is configured according to a third configuration C3 when a back-and-forth movement of the interface element 1 is carried out from the second intermediate stable position P2, in particular in the first direction of traction, and returning to the second intermediate stable position P2.
[0149] Advantageously, the selection device 200; 200' is configured according to a third configuration C3 when the interface element 1 is moved from the third stable position P3 to the second intermediate stable position P2.
[0150] The various manipulations or actions possible at interface element 1 which allow the selection of the different configurations of the selection device are explained below. Transition from the first configuration C1 to the second configuration C2:
[0151] The first position P1 of the interface element 1 defines the first configuration C1 of the function selection device 200; 200'. From this first position P1, when the user pulls the interface element 1 in the first direction D1, the latter reaches the second position P2, thus conforming the function selection device 200; 200' according to the second configuration C2. Transition from the second configuration C2 to the third configuration C3:
[0152] From the second position P2, when the selection device 200; 200' is in the second configuration C2, it is possible to pull the interface element 1 again in the first direction D1. The function selection device 200; 200' then conforms to the third configuration C3 while the interface element 1 reaches a third position P3 or substantially close to P3, which is unstable here. As a result, when the interface element 1 is released by the user, the latter returns to the second stable position P2. The interface element 1 therefore moves back and forth to conform the device to this third configuration C3. Transition from the third configuration C3 to the fourth configuration C4 :
[0153] To configure the function selection device 200; 200' according to the fourth configuration C4, it is first necessary for it to be configured according to the third configuration C3. Thus, once this third configuration C3 has been selected, a new pull on the interface element 1 makes it possible to conform the selection device 200; 200' according to the fourth configuration C4. During this action, the interface element 1 reaches the third position P3 which is stable here. Transition from the fourth configuration C4 to the third configuration C3:
[0154] The third stable position P3 of the interface element 1 therefore defines the fourth configuration C4 of the selection device. From this third and final position P3, by pushing the interface element 1 to the second position P2, the selection device 200; 200' can only be reconfigured into the third configuration C3. Transition from the third configuration C3 to the first configuration C1:
[0155] Whatever the configuration in which the function selection device 200; 200' is previously located, it is impossible to configure it in the second configuration C2 by pushing the interface element 1 in the second direction D2. The sequencing of the mechanism here requires that the selection of this second configuration C2 must necessarily be done by pulling the interface element 1 from the first position P1. As a result, when the interface element 1 is pressed from the second position P2, it inevitably returns to the first position P1, which conforms the selection device 200; 200' according to the first configuration C1. Transition from the second configuration C2 to the first configuration C1 :
[0156] When the function selection device 200; 200' is configured according to the second configuration C2, pressing the interface element 1 in the second direction D2 makes it possible to reach the first position P1, which configures the selection device 200; 200' according to the first configuration C1.
[0157] Thus, from the first position P1 of the interface element 1, each pull carried out on the interface element 1 makes it possible to successively select the different configurations of the selection device according to the predefined order C1, C2, C3 and C4.
[0158] Advantageously, the selection device 200; 200' can only be shaped according to the fourth configuration C4 corresponding to the time setting function after having performed a manipulation of the interface element 1 characterized by a back-and-forth movement, which prevents the user from stopping the movement unexpectedly in the case where the mechanism is equipped with a “seconds stop” or a “balance stop”.
[0159] Preferably, the control interface controlling the selection mechanism or device allowing the selection of the different functions or configurations of the selection device taking part in said mechanism is identical regardless of the embodiment or variant embodiment.
[0160] The function selection device makes it possible to make operational the different chains of the watch mechanism allowing respectively the winding and the adjustments of the different functions of the watch. These chains are for example identical or substantially identical regardless of the embodiment.
[0161] In the described embodiments, the selection devices are used to select particular timepiece functions. However, a selection device according to the invention can be used to select any desired timepiece functions that can be arranged within a timepiece. These can be timepiece functions, in particular time or calendar functions or functions derived from the time. They can also be control or adjustment functions, for example a chime.
[0162] In the embodiments, it is for example possible to select manual winding, a bidirectional adjustment function for the date indication, a monodirectional adjustment function for the day indication and a time setting function, while providing an intuitive interface and the apparent operation of which for the user is substantially identical to that of a known interface of a three-position mechanism.
[0163] In the described embodiments and variants, the number of positions of the indexing element is three and the number of configurations of the selection device is four. However, these numbers can be modified, in particular increased. For example, it would be entirely possible to construct a selection device variant comprising an additional position for the interface element 1, which would make it possible to define at least one new additional configuration. This additional position could, for example, be reached by pulling the interface element 1 once again from the third position P3. The relative movement of the two pulls is locked in this third position P3. An additional pull of the interface element 1 would thus allow the second pull 3; 3' to be indexed by the second indexing device 5; 5' according to a new angular position.As for the first pull 2; 2', the third side 42c; 42c' should just be lengthened to allow it to reach this new angular position.
[0164] Furthermore, the two configurations C2, C3 here selectable when the interface element 1 is arranged in the second position P2 could of course be defined by any other axial position of the interface element. The mechanism could also comprise at least two axial positions of the interface element for which two configurations are selectable. Furthermore, it would also be possible for more than two configurations to be selectable for the same axial position of the interface element.
[0165] In a design variant of the first indexing device 4; 4', it is possible to shape the third flank 42c; 42c' so that it does not tend to bring the first pull tab 2; 2' back into the hollow of the second flank 42b; 42b'. To do this, another elastic element could be capable of bringing said pull tab back into the hollow of the second flank 42b; 42b'.
[0166] The fifth spring 62; 62' for returning the latching member 6; 6' could also alternatively be supported on the frame 100; 100' instead of being supported on the first or second pull tab. Conversely, the fifth spring 62; 62' could also be embedded in the frame 100; 100' and support the latching member 6; 6'.
[0167] Instead of pivoting on the second pull tab 3; 3', the latching member 6; 6' could simply be in the form of a flexible element or an embedded spring, which could for example be included in said pull tab. This spring would then have to have a conformation acting as a beak capable of cooperating with the frame 100; 100' and the first pull tab 2; 2'.
[0168] In the embodiments and variants described, the first and second pull tabs are arranged coaxially. Of course, these pull tabs could not be arranged in this way. The second pull tab 3; 3' can thus be likened to a pivoted rocker, whether or not it is arranged coaxially with the first pull tab 2; 2'.
[0169] As described above, the selection of the third configuration C3 requires that the interface element 1 be pulled from the second position P2 to the third position P3, here unstable, then released by the user, so that it can return to the second position P2. In a design variant, it is conceivable that the so-called unstable position is not exactly on the third position P3. Indeed, it could very well be before or after this third position P3. Ultimately, the amplitude of this back-and-forth movement of the interface element 1 must just be sufficient so that the latching member 6; 6' can lock the relative movement of the two pulls at the end of this action.
[0170] In another embodiment not shown, the watch mechanism 800; 800' could comprise as many winding and / or adjustment chains as there are configurations selectable by the function selection device 200; 200'. In other words, each selection of a given configuration could correspond to the engagement of a specific and dedicated winding or adjustment chain.
[0171] Of course, in another embodiment not shown, the clockwork mechanism 800; 800' could comprise a manual winding chain which could be engaged not by a vertical clutch, but by means of a sliding pinion integral in rotation with the control stem and capable of moving in the direction of the control stem.
[0172] In the embodiments and variants described, a control stem 1 acts as an interface element on the first pull 2; 2' which is directly engaged with the interface element 1. Of course, the first pull 2; 2' could be connected indirectly to the interface element 1, for example by means of one or more rockers or stems. In a first example, the selection of functions could be done using a crown arranged on a secondary stem parallel to the interface element 1, by means of a means kinematically connecting the two stems. This type of arrangement is found in particular in constructions in which it is necessary to offset the position of the crown relative to that of the stem of the movement.In a second example, the selection could be made using a crown arranged on a secondary rod parallel to the axes of the needles, by means of a means making it possible to control the translation of a rod similar to that of the interface element 1 described in this document by the translation of this alternative interface means.
[0173] In the same logic, it is entirely conceivable that the actuation of this function selection device is also done by another interface means, such as, for example, a rotating bezel. In other words, the different translational movements of the interface element 1, making it possible to select the different configurations of the selection device, could be substituted by rotational movements of another interface means, for example, a rotating bezel.
[0174] Although certainly less intuitive for the user, the directions D1 and D2 described so far could also be reversed. The operation of the entire mechanism would therefore also be reversed.
[0175] The elements of the first and second indexing devices 4; 4', 5; 5' may be shaped according to any geometries so as to allow the stable positioning of the pull device 150; 150' comprising the first and second pulls 2; 2', 3; 3'. In particular, the elements of the first and second indexing devices 4; 4', 5; 5' may of course be shaped according to any geometries so as to allow the stable positioning of the first pull 2; 2' for at least a first stable position of the interface element 1 and to allow the stable positioning of the second pull 3; 3' for at least a second stable position of the interface element 1.
[0176] According to the invention as claimed, the selection device or the watch mechanism comprises a single interface element 1, in particular a single control stem 1, which can be manipulated by the user. By manipulating this single interface element 1, the user can: select all configurations of the selection device, select several or all of the watch functions, and operate each of these watch functions.
[0177] According to the invention as claimed, the selection device or the watch mechanism is arranged so that each configuration of the selection device is defined by a translational movement of the interface element 1 and, in each of these configurations, the actuation of the watch function is carried out by a rotational movement of the interface element. In other words, whatever the configuration, the user cannot change the configuration of the selection device by rotating the interface element 1.
[0178] According to the invention as claimed, for each configuration of the selection device, the watch mechanism makes it possible to act on one or more watch functions by rotating the interface element 1, in particular according to its direction of rotation.
[0179] Preferably, regardless of the embodiment or variant, the selection device or the watch mechanism is arranged so that, from the first position P1 of the interface element 1, different pulling actions performed on the interface element 1 make it possible to successively select the different configurations of the selection device, in particular according to the predefined order C1, C2, C3 and C4. According to the invention as claimed, the user only needs to perform pulling actions on the interface element 1 to reach the different configurations of the selection device. Preferably, regardless of the embodiment or variant, the selection device or the watch mechanism is arranged so that the last configuration that can be reached, by applying the different pulling actions performed on the interface element 1, is a configuration corresponding to the time setting.
[0180] Throughout this document, "pull rod" preferably means a rocker whose position is controlled by an interface element, in particular a control rod, directly for example by means of a pull rod stud and cooperating with a groove made on the control rod. "Pull rod" preferably also means a rocker whose position is controlled directly by the action of another pull rod.
[0181] Throughout this document, "top view" means a view from the face of the movement located on the dial side.
[0182] Throughout this document, "indexing of an element", "angular indexing of an element" or "positional indexing of an element" means the definition of different stable positions of an element. These stable positions may be separated by a continuum of unstable intermediate positions. Between two stable positions or two indexed positions or two indexing positions, the element passes transiently through a continuum of unstable or less stable intermediate positions.
[0183] By "stable position" is meant a given position of the interface element 1, of the first pull tab or of the second pull tab (or rocker), once the interface element 1 has been released by the user. In particular, by "stable axial position" is meant a given axial position of the interface element 1 once the latter has been released by the user.
[0184] This “stable position” is defined by the first indexing device 4; 4' and / or by the second indexing device 5; 5'.
[0185] By "unstable position" is meant a given position of the interface element 1 which is exclusively defined by a maintained action of a user. Once the interface element 1 is released, the latter returns to a stable position, different from the unstable position.
[0186] By "pull device" 150; 150', we mean a device comprising at least two pivoted rockers connected to each other and movable relative to each other. A first rocker 2; 2' may meet the definition of "pull", the latter being in direct engagement with a control rod. A second rocker 3; 3' may also meet the definition of pull, knowing that the latter has a conformation substantially equivalent to that of the first rocker 2; 2', and that this second rocker 3; 3' is pivoted coaxially to the first rocker 2; 2'. However, this second rocker is not necessarily pivoted coaxially to the first rocker.
[0187] Throughout this document, the term "configuration" of the function selection device refers to a very specific arrangement or conformation of the elements taking part in the mechanism, making it possible to make the winding and / or adjustment chains operational or to engage them.
[0188] Concerning the "functions" of the movement which can be acted upon with the mechanism, throughout this document, "function" means any manual winding of an energy storage spring, any correction of time indications or those derived from the time, and more generally any additional functions which can be arranged on a timepiece.
[0189] By "sequential" mechanism, we mean here a mechanism capable of selecting different configurations of a selection device for the same stable position of a control member.
[0190] The device according to the invention can be described as a “semi-sequential” mechanism, knowing that it allows both the selection of different configurations of a selection device by moving an interface element between various stable positions, and at least one configuration of said selection device by a back-and-forth movement of the interface element, in particular from a given stable position to this same stable position.
[0191] Throughout this document, the terms "adjustment function" and "correction function" are used synonymously.
[0192] Throughout this document, the studs preferably have a cylindrical shape. More generally, a stud of an element preferably consists of a finger extending perpendicularly or substantially perpendicularly to a plane along which the rest of the element extends. For example, a stud is constituted by a pin or a dowel.
[0193] Throughout the document, the cooperation of the first and second desmodromic connecting elements makes it possible in particular to configure the selection device from one given configuration to another. In particular, it makes it possible, when changing from one configuration to another, to move the rocker 402 into different angular positions under the effect of the movement of the rocker 14, and this independently of any return spring.
[0194] In other words, by "desmodromic linkage" we mean a linkage arranged so as to allow the position of the second flip-flop 402 to be defined from the position of the first flip-flop 14 without using a return spring of the second flip-flop against the first flip-flop. This desmodromic linkage makes it possible to define, unequivocally, a position of the second flip-flop for each of several positions of the first flip-flop. Thus, this does not exclude that in one or more particular positions of the first flip-flop, the position of the second flip-flop is not defined unequivocally (see for example the configuration of the Figure 11 ), in particular that the second rocker can move angularly over a given range without movement of the first rocker.
[0195] A movement of the flip-flop 402 carried out independently of the movement of the flip-flop 14 is nevertheless possible, in particular when the selection device is configured according to the third configuration C3. In this third configuration, the first and second desmodromic connecting elements are arranged such that they allow the flip-flop 402 to be positioned according to a third angular position.
[0196] In the various embodiments and variants, the interface element may be indexed in position: by the first indexing device in one or more first positions, and by the second indexing device in one or more second positions, exclusively.
[0197] Additionally, the interface element may be indexed in position, in one or more third positions: by the first indexing device and by the second indexing device redundantly, or by the first indexing device and by the second indexing device complementaryly,
[0198] The described solutions have a mode of operation close to that of known mechanisms, while offering the possibility of selecting a larger number of adjustment configurations. In addition, this solution makes it possible to overcome all the drawbacks identified in the state of the art.
[0199] The solutions described allow for quick adjustments of several display functions, including several calendar display functions. For example, the solutions described allow for quick, bidirectional adjustment of a date display, as well as adjustment of a weekday display.
[0200] The described solutions allow the implementation of a single interface means with an intuitive actuation mode, while allowing the adjustment of a large number of functions.
