Definitions

  • the present invention relates to a device for selecting and actuating at least two functions of a watch movement.
  • the present invention relates to a device for correcting at least two displays of a watch movement.
  • Such correction devices are used in complication watches in order to be able to correct the information displayed by these different complications.
  • the complications to be corrected in connection with the present invention relate more particularly to “astronomical” complications, such as the indication of the date, the day of the week, the month, or the moon phase.
  • a watch is equipped with a winding stem, which can occupy a first, neutral position for winding, a second, pulled-out position for correcting the date for example, and a third, pulled-out position for setting the time.
  • a single complication can therefore generally be corrected using the winding stem, which therefore allows three functions of the watch to be acted upon (winding, correcting the date and setting the time for example).
  • EP 2 701 015 a device for correcting a plurality of time functions displayed by a timepiece.
  • This correction device comprises a push-piece for selecting the complication to be corrected, the actuation of which rotates a selection wheel carrying a corrector wheel in order to bring said corrector wheel into engagement with a corrector pinion of the selected complication to be corrected, said corrector wheel being furthermore rotated by the winding stem, in one of its two pulled-out positions, by means of a suitable gear train, to in turn rotate said corrector pinion in order to correct said complication.
  • Such a device makes it possible to eliminate all correction pushers, keeping only one pusher to select the complication to be corrected and the winding stem to carry out the correction.
  • this device is not suitable if one wishes to eliminate the use of any pusher, and to be able to select the complication to be corrected and correct said complication solely by rotating movements of two control members.
  • This device is also not suitable if one wishes to eliminate the use of any pusher, and keep only a single control stem, such as the winding stem, to both select the complication to be corrected and correct said complication.
  • the document EP 3 882 718 also describes a device for correcting a number N of complications of a timepiece comprising a mechanism for selecting the complication to be corrected arranged to be actuated by the winding stem.
  • Said winding stem can conventionally occupy a pushed position for winding, a first pulled position for setting the time and a second pulled-out selection/correction position.
  • the winding stem actuated in one direction of rotation allows the selection of the complication to be corrected and actuated in the other direction of rotation allows the correction of the selected complication to be corrected.
  • the correction device further comprises a correcting gear train arranged to be actuated by the winding stem to correct the selected complication to be corrected, N complication correction mechanisms arranged to be capable of cooperating with the correcting gear train to correct their respective complication and a selection mechanism comprising a selection wheel mounted so as to be able to rotate on said frame, and cooperating with the winding stem in its correction/selection position to drive it in rotation.
  • An activation member of the correction mechanism of the selected complication to be corrected is arranged to be moved with the selection wheel so as to cooperate with the correction mechanism of the selected complication to be corrected in order to move it from a passive position, in which said correction mechanism does not cooperate with the selection wheel nor with the corrector gear train nor with its respective complication, to an active position in which said correction mechanism of the selected complication to be corrected can cooperate with the corrector gear train to be actuated when said corrector gear train is activated by the winding stem pivoted in the correction direction in its selection/correction position, in order to cooperate with said selected complication to be corrected to carry out its correction.
  • Such a device certainly makes it possible to eliminate all correction pushers and to select and correct two or more complications using only the winding stem.
  • this device is complex and includes a large number of components, some of which, such as the selection wheel, are bulky.
  • the aim of the present invention is to provide a device for selecting and actuating at least two functions of a watch movement that is simple, compact and that allows the selection and actuation of several functions, in particular functions for correcting at least one complication or display, using a single control member which is preferably the winding stem.
  • the invention also aims to propose a selection and actuation device that makes it possible to avoid having to display the current selection, while remaining simple and quick for the user who is not forced to remember what the last selection made was.
  • the present invention relates to a device for selecting and actuating at least two functions of a watch movement according to claim 1, a watch movement comprising such a device and a timepiece comprising such a movement.
  • the selection and actuation device is intended to equip a watch movement to enable at least two functions of the watch movement to be selected and actuated.
  • the functions to be selected and actuated may be functions for correcting one or more complications or one or more displays, a winding function for a driving member such as a barrel or an adjustment function such as setting the time of a time display.
  • a single control member which can move in rotation and translation allows the selection of functions and their actuation.
  • control member is a winding stem 1.
  • the selection and actuation device makes it possible to select correction functions and to actuate a first and a second correction mechanism 91, 92 represented by their first wheel set in the figures.
  • the winding stem 1 is conventionally arranged to occupy three successive distinct axial positions: a pushed position for winding, a first pulled position for actuating the correction functions and a second pulled position for setting the time.
  • the winding stem 1 carries known manner a winding pinion 2 mounted freely in rotation and a sliding pinion 11 adjusted squarely on the winding stem 1.
  • the winding pinion 2 meshes with a crown wheel 20 kinematically connected in a known manner to the driving member of the movement (for example, in the case of a barrel, via the ratchet fixed squarely on the barrel arbor).
  • a pull rod 12 is pivotally mounted at A and is arranged to switch between three distinct positions when the winding stem 1 is pulled or pushed in a conventional manner by means of its tenon which is housed in a hollow of the winding stem 1.
  • the pull rod 12 comprises a first arm 121 carrying a pin 120 arranged to cooperate with the active end 130 of a pull rod spring 13.
  • the pull rod spring 13 is arranged to determine the three distinct positions of the pull rod 12 and consequently the three successive distinct axial positions of the winding stem 1.
  • the pull-out 12 further comprises a beak 123 arranged to cooperate with a control lever 14 of the sliding pinion 11 pivoted on the movement and subjected to the action of a return spring 15.
  • the control lever 14 cooperates with the sliding pinion 11 via a beak 141 housed in a hollow of said sliding pinion 11 to slide the latter on the winding stem 1 when the control lever 14 pivots.
  • the pull-out 12 further comprises a second arm 122 arranged to cooperate with a time-setting lever 3 pivoted on the movement and subjected to the action of its return spring 31.
  • the time-setting lever 3 carries a pin 32 arranged to pass through an opening 41 of a correction lever 4.
  • the correction lever 4 is pivoted on the movement and carries a main setting wheel 5.
  • the main setting wheel 5 meshes either with a time-setting wheel 33 kinematically connected to the minute train for setting the time of the clockwork movement, or with a correction wheel 6 pivotally mounted at B on the movement.
  • the main setting wheel 5 as well as the correction wheel 6 may have any suitable shape. In particular, they could each comprise several superimposed and integral teeth, added or in one piece, with identical or different modules or numbers of teeth, to allow the main wheel 5 to mesh with the time-setting wheel 33 and with the correction wheel 6 on different levels.
  • the pull-out 12 When the winding stem 1 is in its second pulled out position or time setting position as illustrated in the Figure 6 , the pull-out 12 is in its time-setting position pushed by the pull-out spring 13 against a stop of the corresponding clockwork movement and the control lever 14 of the sliding pinion 11 holds the latter in a position on the winding stem 1 in which said sliding pinion 11 meshes with the main gear 5 which is itself in a position in which it meshes with the timer train represented by the time-setting gear 33.
  • the time-setting function is therefore also carried out conventionally.
  • the selection and actuation device further comprises a selection wheel set 7 kinematically connected to the crown wheel 20.
  • the selection wheel set 7 comprises a selection cam 71 secured to and superimposed on a selection pinion 72 arranged to mesh with the crown wheel 20.
  • the selection cam 71 drives a selection lever 8 pivoted on the movement at B concentrically with the correction gear 6.
  • the selection lever 8 carries a selection gear 81 arranged to mesh with the correction gear 6 whatever the position of the selection lever 8.
  • the selection lever 8 pivots - driven by the selection cam 71 - between a position in which the selection gear 81 is engaged with a first correction mechanism of which only the first mobile 91 is illustrated ( figures 1 , 2 , 3 And 6 ) and a position in which the selection gear 81 is engaged with a second correction mechanism of which only the first mobile 92 is illustrated ( figures 4 And 5 ).
  • the first correction mechanism is arranged to allow the correction of a first mechanism of the watch movement when its first mobile 91 pivots in a first direction and the correction of a second mechanism of the watch movement when the first mobile 91 pivots in a second direction (one mechanism for two functions depending on the direction of rotation of the winding stem).
  • the first and second watch mechanisms may be, for example, a date display mechanism and a month display mechanism.
  • the second correction mechanism is arranged to allow the correction of a third mechanism of the watch movement when its first mobile 92 pivots in a first direction and the correction of a fourth mechanism of the watch movement when the first mobile 92 pivots in a second direction.
  • the third and fourth watch mechanisms may be, for example, a day of the week display mechanism and a moon phase mechanism.
  • first and second correction mechanisms 91, 92 could be arranged to allow correction of a single watch mechanism of the movement in both directions (one mechanism for one function regardless of the direction of rotation of the winding stem).
  • Such correction mechanism are well known to those skilled in the art and will not be described here.
  • the non-selection position does not exist: at rest - the winding stem 1 in its pushed winding position - the device retains the last selection made.
  • the Figure 1 illustrates the device in a position in which the selected correction mechanism is the first correction mechanism 91.
  • the winding stem 1 To reach this position and select the first correction mechanism 91, the winding stem 1 must be axially moved into its first pushed winding position. The pull 12 is then in its winding position constrained by the pull spring 13 and the control lever 14 of the sliding pinion 11 holds the latter in a position on the winding stem 1 in which said sliding pinion 11 meshes with the winding pinion 2.
  • the pull-out 12 in its winding position does not actuate the time-setting lever 3 which is in its rest position maintained by its return spring 31.
  • the pin 32 cooperates with the opening 41 of the correction lever 4 to maintain the latter in a correction position in which the main reference 5 does not mesh with the time-setting reference 33 but meshes with the correction reference 6.
  • the winding stem 1 is pivoted in a first direction driving the sliding pinion 11, the winding pinion 2 and the crown wheel 20.
  • the crown wheel 20 is engaged with a toothing 721 of the selection pinion 72 of the selection wheel set 7 and drives the latter.
  • the selection cam 71 secured to the selection pinion 72 then pivots until a finger 711 of said cam 71 enters the fork 82 of the selection lever 8.
  • the selection cam 71 drives the selection rocker 8 which pivots to reach its first selection position in which the selection return 81 meshes with the first correction mechanism 91.
  • the selection cam 71 drives the selection rocker 8 until an arm of the fork 82 of the selection rocker 8 comes into abutment on the selection cam 71. This stop position is illustrated in the Figure 1 .
  • the first correction mechanism 91 is selected.
  • the selection pinion 72 also comprises a toothless section 722 and a detent spring 73 which is arranged to cooperate with a beak 712 of the selection cam 71.
  • the selection wheel set 7 is arranged to be able to detent at the end of its travel if the winding stem 1 and therefore the crown wheel 20 continue to rotate in the first direction - winding direction - which makes it possible to select the first correction mechanism while the selection lever 8 has reached its first selection position in abutment on the selection cam 71.
  • This detent position is illustrated in FIG.
  • Figure 2 the crown wheel 20 continues to rotate driven by the winding stem 1 pivoted in the first direction, but at the end of its travel, when the selection lever 8 is in its first selection position in abutment on the selection cam 71, the crown wheel 20 cooperates with the toothless section 722 of the selection pinion to no longer drive the selection cam 71 while the release spring 73 resting on the beak 712 ensures that the teeth 721 of the selection pinion 72 remain in the path of the crown wheel 20 in order to be able to mesh with it when the winding stem 1 is turned in the other direction.
  • the device - in particular the selection wheel 7 - is arranged so that the selection lever 8 reaches its first selection position in abutment on the selection cam 71 after approximately 1 turn of the winding stem 1.
  • Other choices are of course possible (more or less than one turn).
  • the sliding pinion 11 drives the main setting wheel 5, the correction setting wheel 6, the selection setting wheel 81 and finally the first correction mechanism 91.
  • the first correction mechanism 91 corrects a first watch mechanism such as the date
  • the first correction mechanism 91 corrects a second watch mechanism such as the month display.
  • the device By pulling the winding stem 1 into its second pulled-out position, the device moves into a configuration shown in Figure 6 .
  • the pull tab 12 pivots in its time-setting position and its arm 122 actuates the time-setting lever 3 which pivots against the action of its return spring 31 from its rest position into its time-setting position.
  • the pin 32 moves into the opening 41 of the correction lever 4 which pivots and moves the main reference 5 into a position in which it meshes with the time-setting reference 33 and no longer meshes with the correction reference 6.
  • the selection lever 8 has not moved during the axial movement of the winding stem 1.
  • the control lever 14 of the sliding pinion 11 has continued its rotation pushed by the beak 123 of the pull rod 12, in doing so it slides the sliding pinion 11 on the winding stem 1 to keep it in a position in which it is engaged with the main wheel 5 which has moved.
  • the winding stem 1 To select another function to be actuated, in particular to select the second correction mechanism 92, the winding stem 1 must be moved axially to return it to its first pushed position. The device is then again in the configuration of the Figure 1 .
  • the winding stem 1 must be turned in a second direction, opposite to the first.
  • the winding stem 1 therefore pivots in a second direction and drives the sliding pinion 11, the winding pinion 2 and the crown wheel 20.
  • the detent spring 73 minimises the teeth 721 of the selection pinion 72 to be in the path of the crown wheel 20.
  • the crown wheel 20 drives the selection pinion 72 and the selection cam 71.
  • the finger 711 of the selection cam 71 catches the fork 82 of the selection rocker 8 again and pivots it into its second selection position.
  • the selection gear 81 then meshes with the second correction mechanism 92.
  • the selection cam 71 drives the selection rocker 8 until an arm of the fork 82 of the selection rocker 8 comes into abutment on the selection cam 71. This abutment position is illustrated in the Figure 4 .
  • the device - in particular the selection wheel 7 - is arranged so that the selection lever 8 reaches its second selection position in abutment on the selection cam 71 after approximately 1 turn of the winding stem 1.
  • Other choices are of course possible (more or less than one turn).
  • the second correction mechanism 92 is selected.
  • the crown wheel 20 can continue to rotate driven by the winding stem 1 pivoted in the second direction, but at the end of the travel, when the selection lever 8 is in its second selection position in abutment on the selection cam 71, the crown wheel 20 cooperates with the toothless section 722 of the selection pinion 72 to no longer drive the selection cam 71 while the detent spring 73 bearing on the finger 711 ensures that the teeth 721 of the selection pinion 72 remains in the path of the crown wheel 20 so that it can mesh with it when the winding stem 1 is turned in the first direction.
  • the sliding pinion 11 drives the main gear 5, the correction gear 6, the selection gear 81 and finally the second correction mechanism 92.
  • the second correction mechanism 92 corrects a third watch mechanism such as the day of the week display and by rotating the winding stem 1 in a second direction, the second correction mechanism 92 corrects a fourth watch mechanism such as the moon phase display.
  • a selection and actuation device is arranged to be able to select and actuate at least two functions of a watch movement.
  • the functions to be selected and actuated can be functions for correcting one or more complications or one or more displays, a function for winding a driving member such as a barrel or an adjustment function such as setting the time of a time display.
  • the control member is arranged to take at least two distinct axial positions: a selection position and an actuation position.
  • the device is arranged so that a rotation in a first direction of the control member in the selection position places the device in a first configuration in which a first function of the timepiece movement is selected.
  • the device is arranged so that in this first selection configuration, the first selected function can be actuated when the control member is pivoted while it is in its actuation position.
  • the device is arranged so that a rotation in a second direction of the control member in the selection position places the device in a second configuration in which a second function of the timepiece movement is selected.
  • the device is arranged so that in this second selection configuration, the second function can be actuated when the control member is pivoted while it is in its actuation position.
  • each selection lever allows selection between two distinct functions of a pair of functions of the watch movement.
  • the control member is then arranged to take a selection position and as many axial actuating positions as there are pairs of distinct functions. In each of these actuating positions, a rotation of the control member causes the function of the pair of functions selected by the corresponding selection lever to be actuated.
  • a second selection lever pivoted concentrically to the correction wheel 6 and controlled by a second selection cam of the selection wheel set 7 can be added.
  • the second selection lever carries a second selection wheel arranged to be in constant engagement with the correction wheel 6 and in engagement with a third mechanism for actuating a function C of the watch movement or a fourth mechanism for actuating a function D of the watch movement depending on the position of the second correction lever.
  • a third mechanism for actuating a function C of the watch movement or a fourth mechanism for actuating a function D of the watch movement depending on the position of the second correction lever In the pushed position of the winding stem, it is therefore possible to simultaneously select between the first and second correction mechanisms 91, 92 and functions C or D. Then, in the first pulled-out position of the winding stem, the first or second correction mechanism 91, 92 is actuated depending on what has been selected.
  • the winding stem in this case takes a third pulled-out position in which, by pivoting said stem, functions C or D can be actuated depending on what has been selected.
  • selection positions can be provided, each allowing a function to be selected between two functions of one or more pairs of distinct functions of the clockwork movement and as many actuation positions as there are pairs of functions.
  • the present invention relates to a device for selecting and actuating n pairs of distinct functions of a watch movement, for n greater than or equal to 1.
  • the device comprises a control member movable in translation and in rotation and arranged to occupy x axial selection positions for x ranging from 1 to n and n distinct axial actuation positions each associated with a determined pair of functions.
  • the device is arranged so that a rotation in a first direction of the control member places the device in a configuration in which a first function of at least one of the n pairs of functions is selected and so that a rotation of the control member in a second direction places the device in a configuration in which the second function of the at least one of the n pairs of functions is selected.
  • rotation of the control member causes actuation of the first function of the associated pair of functions when the device is in a configuration in which said first function has been selected in the corresponding selection position or actuation of the second function of the associated pair of functions when the device is in a configuration in which said second function has been selected in the corresponding position.
  • x and n are equal to 1: there is a single selection position which allows selection between two functions A or B forming a pair of distinct functions: correction A via the first correction mechanism 91 and correction B via the second correction mechanism 92.
  • x 1 (we keep a single selection position)
  • n 2: there are two pairs of distinct functions (pair of functions A, B and pair of functions C, D).
  • x can be 2 and there is a selection position for each of the pairs of functions: a selection position to choose between A and B and a selection position to choose between C and D.
  • the number of selection positions can be between 1 and n where n is the number of pairs of functions for which one wishes to make a choice, since it is possible to simultaneously choose a function from each of the n pairs of functions while the number of actuation positions must be exactly n to be able to independently actuate the selected function from each of the n pairs of functions.
  • the device can be arranged so that in the selection position(s), another function of the movement can be actuated: this is particularly the case in the illustrated embodiment, in which the selection position is the winding position, in which the device is arranged to allow the winding function of a motor member of the movement to be actuated.
  • control member is preferably the winding stem arranged to take another axial position which is the time-setting position and which is distinct from the selection positions and the actuation positions, the winding position also acting as a selection position.
  • the device is arranged so that the selection wheel set is not driven when the winding stem moves from one of its selection or actuation positions to its time-setting position or when the winding stem rotates into its time-setting position.
  • the selection wheel is arranged to move the selection rocker(s) into their first, respectively second position after a rotation of the control member by an angle A in the first, respectively second direction and to maintain said rocker in this first, respectively second selection position without breakage when the rotation of the control member in the first, respectively second direction continues beyond this angle A (unlatching).
  • the selection wheel preferably comprises a selection pinion arranged to be kinematically connected to the control member, integral with the selection cam(s) and having a toothed sector and a toothless sector while the selection cam is subjected to the action of a unlatching spring.
  • the angle A is less than 360°, is preferably between 150° and 250° and even more preferably is approximately 200°: it is thus possible to indicate to the wearer of the watch that it is necessary to make a turn of the stem (simple indication which avoids having to count turns, which would be tedious) while maintaining a safety feature (included in the difference between 360° and 200° for example and/or the ratio between the winding pinion 2 and the selection pinion 72) in order to guarantee that the selection is made.
  • the selection and actuation device is simple, compact and allows the selection and actuation of at least two functions of a watch movement, and in particular the correction of complications, using a single control member, which is preferably the winding stem.
  • the aesthetics of the timepiece are thus preserved while offering selection and actuation operations that are easy to implement for a user.
  • the function selection sequence is simple (put the control member in its selection position, turn the control member one turn in one direction) which makes it possible to do without a display device for the selected function while avoiding the user having to remember the last function selected since he can always simply select the function to be activated.
