Description:
TECHNICAL FIELD 
       [0001]    The present invention relates to timepieces. It more particularly relates to a mechanism for selecting and actuating n functions of a clockwork movement, where n is an integer greater than or equal to 1, preferably greater than or equal to 2, more preferably greater than or equal to 3, comprising a winding stem ending with a crown, a device for actuating a function, kinematically connected to the crown and arranged to move and occupy n selecting positions and n actuating positions, in which the actuating device is kinematically connected to an organ for actuating the selected function, and a selector device arranged to move the actuating device into a selecting position. The present invention also relates to a mechanical timepiece comprising a clockwork movement and a mechanism for selecting and actuating n functions of said clockwork movement. 
       BACKGROUND OF THE INVENTION 
       [0002]    Such a selection and correction mechanism is for example described in patent EP 2 214 066 and applies to a timepiece provided with first and second time indicating organs. This correction mechanism comprises a winding stem, a corrector wheel mounted sliding between first and second correction positions in which said wheel is kinematically connected with the first and second time indicating organs, respectively, means for driving said corrector wheel using the winding stem, and a mechanism for selecting the correction position comprising a selector arm cooperating with said corrector wheel to drive it from the first correction position to the second correction position, an angular positioning organ of the selector arm and a control organ of said angular positioning organ. 
         [0003]    However, due to its construction, this mechanism is limited to correcting only two functions. 
         [0004]    Also known is application CH 702 548, which describes a selection mechanism capable of being in a neutral position or moving between two correction positions by pressing on the winding crown, the correction being done solely by rotating the winding crown, without having to pull on the winding stem. To that end, the mechanism comprises a lever having two arms, on each of which a correction wheel is mounted. The lever pivots to select and actuate one or the other of the two functions to be corrected using one of the correction wheels placed in contact with an organ of the function to be corrected. However, if the neutral position is not taken into account in which the lever is in the neutral position, this mechanism, due to its construction, is limited to correcting only two functions, the lever only being able to pivot between two positions. 
         [0005]    Also known is application CH 702 803, which describes a correction mechanism comprising correction levers arranged to increment the counting organs, a control lever mounted pivoting along a first rotation axis and an arm mounted pivoting on said control lever along a second rotation axis. The arm moves angularly relative to the control lever in response to a rotation of the crown to be placed across from either of the correction levers. The control lever pivots to actuate the selected correction lever in response to an action on a push-piece. The correction therefore can only be done by incrementing the various counting organs, which makes bidirectional operation impossible. Only unidirectional correction of the counting organs is possible. Furthermore, this mechanism comprises a large number of components, which are relatively complex to implement. Such a solution, which only uses levers and cams, risks being fairly imprecise, the precision of the components (cams, arms, correction levers) being crucial for the system to operate correctly. Furthermore, the linear guiding of one of the levers is done through a groove in which a guide finger moves. The system is relatively sensitive to adjust and may create blockages. 
         [0006]    One aim of the present invention is therefore to offset these drawbacks by proposing a mechanism for selecting and actuating n functions of a clockwork movement making it possible to select and actuate at least three different functions of a clockwork movement. 
         [0007]    Another aim of the present invention is to propose a mechanism for selecting and actuating n functions of a clockwork movement making it possible to actuate the functions bidirectionally. 
       BRIEF DESCRIPTION OF THE INVENTION 
       [0008]    To that end, and according to the present invention, proposed is a mechanism for selecting and actuating n functions of a clockwork movement, where n is an integer greater than or equal to 1, preferably greater than or equal to 2, still more preferably greater than or equal to 3, comprising a winding stem ending with a crown, a device for actuating a function, kinematically connected to the crown and arranged to move and occupy n selecting positions and n actuating positions, actuating positions in which the actuating device is kinematically connected to an organ for actuating the selected function, and a selector device arranged to move the actuating device into a selecting position.

         [0016]    Particularly advantageously, said base may have at least n tracks arranged to guide the actuating device during its movements. The actuating device may comprise a first pin arranged to travel in the tracks. The base may further comprise a groove and the actuating device may comprise a second pin arranged to travel in the groove. 
         [0017]    Particularly advantageously, the mechanism according to the invention may further comprise a safety device comprising said base and said tracks, at least n of said tracks corresponding to the actuating positions being arranged to lock the actuating device in the selected actuating position. 
         [0018]    Preferably, the mechanism according to the invention further comprises a mechanism for indicating the selected function. 
         [0019]    Advantageously, said indicator mechanism of the selected function comprises a wheel secured to the cam of the selector device, and a disc bearing information relative to the functions and arranged to be displayed in an aperture, said wheel and said disc being kinematically connected. 
         [0020]    According to one preferred embodiment of the invention, the functions to be selected are chosen from among the group comprising a date correction function, a winding function and a setting function. 
         [0021]    The present invention also relates to a timepiece comprising a clockwork movement, as well as a mechanism for selecting and actuating n functions of said clockwork movement as defined above.

     DETAILED DESCRIPTION OF THE INVENTION 
       [0032]    In reference to  FIG. 1 , a mechanism  1  is shown for selecting and actuating n functions of a clockwork movement, n being equal to 3 in this specific embodiment. Of course, the invention applies to a correction mechanism preferably having at least two functions, and still more preferably at least 3 functions. 
         [0033]    The mechanism  1  comprises a winding stem  2  ending with a winding crown (not shown), a device for actuating a function  4 , a selector device  6 , a safety device  8  and a mechanism indicating the selected function  10 . 
         [0034]    The mechanism  1  also comprises a winding-pinion  12 , a clutch-pinion  14 , the positioning of the clutch-pinion  14  being assured by a pull-out piece  16  and a lever  18 . A lever return spring  20  is also provided. All of these elements and their operation are known by those skilled in the art and do not require a more detailed description. 
         [0035]    Furthermore, organs are also provided for actuating the selected function  21 ,  22  and  23 , each being kinematically connected to the mechanism corresponding to said selected function. 
         [0036]    The functions to be selected may for example be chosen from the group comprising a date correction function, a winding function and a setting function. Of course, any other mechanism corresponding to another function may be actuated using an appropriate actuating organ. 
         [0037]    The actuating device  4  is kinematically connected to the crown and arranged to move and occupy 3 selecting positions and 3 actuating positions, the selecting positions being different from the actuating positions. In selecting positions, the actuating device  4  is positioned facing the actuating organ  21 ,  22 ,  23  for the selected function without being able to cooperate with said actuating organ  21 ,  22 ,  23 . In actuating positions, the actuating device  4  is kinematically connected to one of the actuating organs  21 ,  22 ,  23  for the selected function. 
         [0038]    More particularly and according to the invention, the mechanism further comprises a base  32  on which the actuating device  4  is rotatably and translatably mounted to rotate and be positioned, in a selecting position, facing the actuating organ  21 ,  22 ,  23  for the selected function under the action of the selector device  6 , then to move into its actuating position to cooperate with said actuating organ  21 ,  22 ,  23  for the selected function under the action of an axial movement of the winding stem  2 , preferably toward the outside of the movement. Of course, by adapting the configuration of the stem, the pull-out piece and the lever, the axial movement of the winding stem could be done toward the inside of the movement. 
         [0039]    More specifically, the actuating device  4  comprises a support  24 , as well as a pivoting base  25 , between which a single actuating wheel  26  designed to cooperate with each of the actuating organs  21 ,  22  and  23  for the selected function and an intermediate wheel  28  meshing on the one hand with the clutch-pinion  14 , and therefore the winding stem  2 , and on the other hand with said actuating wheel  26 , are rotatably mounted. Thus, the actuating wheel  26  is kinematically connected to the winding stem  2  such that each of the actuating organs is actuated by rotating the crown connected to the winding stem  2 . The actuating wheel  26  is mounted rotatably around a pin  27  mounted crossing through the support  24  and the pivoting base  25 . The intermediate wheel  28  is mounted rotatable around a pin  29  mounted passing through the support  24 . 
         [0040]    Furthermore, the safety device  8  comprises a base  32  mounted fixed on the frame of the movement and having, in illustrated variant, three semi-oblong tracks  34  communicating with one another and able to receive the pin  27  when the actuating device  4  is in its actuating position so as to lock it in one of said tracks  34 . Of course, the base may also be in a single piece with the main plate, a plate or a bar provided in the movement. 
         [0041]    The base  32  also includes a split blom stud  33  having a central groove  36  in which the pin  19  can travel when the actuating device  4  enters the actuating position, as will be described below. 
         [0042]    As more specifically shown in  FIG. 2 , the pivoting base  25  comprises a rounded part  25   a  arranged to pivot around the split blom stud  33  and an elongated part  25   b  including, at its end, an oblong opening  30  in which the pin  27  is inserted and slides when the actuating device  4  goes to the actuating position, as will be described below. Thus, the support  24  bearing the two wheels  26  and  28  is mounted sliding on the pivoting base  25 . 
         [0043]    As a result, the actuating device  4  is mounted rotatably and translatably relative to the base  32 . 
         [0044]    Furthermore, the rounded part  25   a  of the pivoting base  25  includes a lateral hollow  38  arranged to cooperate with the selector device  6  and form a ball-joint connection, as will be described below. 
         [0045]    On the side of the winding stem, the support  24  comprises a head  24   a  including a circular groove  40  in which a pin  42  secured to the lever  18  travels. The support  24  is thus arranged to cooperate with the lever  18  while being able to pivot relative to the latter. 
         [0046]    In reference to  FIGS. 1 and 2 , the selector device  6  comprises a selector organ  50 , such as a cam wheel, arranged to be actuated by a control organ, such as a push-piece  52  integrated into the crown, for example. The action of the push-piece  52  is transmitted to the selector organ  50  by means of a lever  54  mounted pivoting on the frame and comprising a beak  56  arranged to actuate and pivot the selector organ  50  each time the push-piece  52  is pressed. Of course, the control organ may be any other appropriate organ, such as a trigger or a secondary crown, arranged to rotate the selector organ  50 . The controller may also be independent of the crown, and be provided around the dial, in a place different from that of the winding stem. 
         [0047]    In another alternative embodiment that is not shown, the push-piece and the present winding stem could be replaced by a three-position stem ending with a crown and arranged to be positioned:
       in a position T 0 , in which the stem is pushed, the rotation of the crown allowing winding of the movement,   in a position T 1 , in which the stem is pulled in the first position, the mechanism being suitable so that the rotation of the crown drives the rotation of the selector organ to move the actuating device into its selecting position,   in a position T 2 , in which the stem is pulled into a second position to move the actuating device into its actuating position, the rotation of the crown driving the actuating of the actuating organ  21  to  23  selected via the intermediate wheel  28  and the actuating wheel  26 .       
 
         [0051]    The selector device  6  also comprises a cam  58  secured to the selector organ  50  and a feeler-spindle  60  arranged to cooperate on the one hand with the cam  58  and on the other hand with the actuating device  4 . To that end, the feeler-spindle  60  comprises a first arm  61  that bears against the cam  58  and a second arm  62  mounted in a ball-joint connection with the hollow  38  of the pivoting base  25  of the actuating device  4 , such that said second arm  62  cooperates with said base  25 . The first arm  61  is kept bearing against the cam  58  via a return spring  64  acting against a catch  65  provided on the pivoting base  25 . 
         [0052]    The selector organ  50  and the shape of the cam  58  are chosen so that said selector organ  50  and said cam  58  perform a 45° rotation each time the push-piece is pushed. In the illustrated variant, the functions are selected in order, the reverse order having to be respected to return to the initial function. Of course, by choosing another configuration of the lever  54 , the selector organ  50  and the push-piece  52  in particular, the rotation angle can be different. Furthermore, by modifying the shape of the cam  58 , the return to the initial function may be done directly after having selected the third function. 
         [0053]    In another alternative embodiment that is not shown, the selector organ may be a shuttle system, replacing the cam wheel. The shuttle is arranged to perform a rotational to-and-fro movement to occupy two positions set by a jumper-spring. The system makes it possible to eliminate the cam  58  and the lever  54 . As described above, a feeler-spindle  60  is provided comprising a first arm  61  bearing against the shuttle and a second arm  62  for example mounted in a ball-joint connection or any other type of connection with the hollow  38  of the pivoting base  25 . The position of the shuttle therefore also defines the position of the actuating device  4 . 
         [0054]    In reference to  FIG. 1 , the indicator mechanism for the selected function comprises a toothed wheel  66  secured to the cam  58  of the selector device  6 , and a disc  68 , mounted rotating on the frame and bearing information relative to the functions arranged so as to be displayed in turn in an aperture (not shown). The wheel  66  and the disc  68  are kinematically connected via an intermediate wheel  70  secured to the disc  68 . The information relative to the functions here consists of numbers 1, 2, 3 corresponding to the three functions to be selected and actuated. The information could also assume any form other than numbers 1, 2, 3, such as colors or symbols. In another variant that is not shown, the disc  68  includes a toothing arranged to cooperate with the toothed wheel  66 , the intermediate wheel  70  being eliminated. In another variant that is not shown, the wheel  66  does not include a toothing, and is kinematically connected to the disc  68  by means of other appropriate connecting means, such as belts or connecting-rods. Furthermore, it is possible to provide intermediate gear trains, between the wheel  66  and the disc  68 , for example to reverse the rotation direction of the disc  68  or to further separate the display provided on the disc  68 . Of course, any other embodiment for displaying information relative to the functions can be implemented. For example, the disc  68  can be replaced by a hand mounted on an axis kinematically connected to the wheel  66 , the hand being arranged to point to the information relative to the functions located on a stationary dial. 
         [0055]    The operation of the mechanism according to the invention is as follows: 
         [0056]    In reference to  FIGS. 3 and 4 , when the user wishes to select function no.  1 , he presses on the push-piece  52  so as to pivot the lever  54  into the position shown in dotted lines in  FIG. 2 , which causes the selector organ  50  and the cam  58  to rotate by 45° in the clockwise direction. The feeler-spindle  60  pivots while entraining the pivoting base  25 , which arrives in selecting position no.  1 , shown in  FIG. 3 . In the same movement, the support  24  of the actuating device, connected to the base  25  by pins  27  and  29 , pivots with the base  25  to also be in selecting position no.  1  shown in  FIG. 3 , the wheel  26  being located facing the actuating organ  21  for function no.  1 . 
         [0057]    Also in that same movement, the first toothed wheel  66  of the mechanism indicating the selected function  10  pivots and meshes with the intermediate wheel  70  so as to rotate the second wheel  68  to display the number 1 in an aperture. 
         [0058]    In order to actuate the actuating organ  21  relative to function no.  1 , the user pulls the stem  2  toward the outside of the movement so that the clutch-pinion  14  moves. The positioning of the clutch-pinion  14  relative to the pull-out piece  16  and the lever  18  is a mechanism known by those skilled in the art that does not require further explanation. 
         [0059]    Via the pin  42 , the pivoting of the lever  18  also drives the sliding or movement of the support  24  relative to the base  25 , toward the actuating organ  21 . In this movement, the pin  27  slides in the opening  30  of the pivoting base  25  and becomes housed at the bottom of the first track  34  of the base  32  of the safety device, and the pin  29  moves linearly in the groove  36  of the split blom stud  33  of the base  32 . As a result, the support  24  moves linearly, via the pin  29 , as well as in the direction of the first track  34 , via the pin  27 . The movement of the support  24  is therefore a combination of linear and rotational movement. The actuating device  4  is then in actuating position no.  1 , the wheel  26 , supported by the support, then being able to mesh with said actuating organ  21 , as shown in  FIG. 4 . Function no.  1  is actuated by rotating the winding crown, which drives the rotation of the clutch-pinion  14 , and therefore of the intermediate wheel  28  and the wheel  26 . 
         [0060]    The support  24  is kept in actuating position no.  1  by the safety device using the pin  27  housed at the bottom of the track of the base  32 . 
         [0061]    Pressing the winding stem  2  in the direction of the movement drives the first sliding of the support  24 , such that the wheel  26  is extricated from the actuating organ  21 , the mechanism returning to selecting position no.  1  shown in  FIG. 3 . 
         [0062]    In reference to  FIGS. 5 and 6 , when the user wishes to select function no.  2 , he presses on the push-piece  52  so as to pivot the lever  54 , which once again causes the selector organ  50  and the cam  58  to rotate by 45° in the clockwise direction. The feeler-spindle  60  pivots by rotating the pivoting base  25 , which reaches selecting position no.  2  shown in  FIG. 2 . In that same movement, the support  24  of the actuating device pivots with the base  25  so as also to be placed in selecting position no.  2  shown in  FIG. 5 , the wheel  26  being located facing the actuating organ  22  for function no.  2 . 
         [0063]    Also in that same movement, the first toothed wheel  66  of the indicator mechanism for the selected function  10  pivots and meshes with the intermediate wheel  70  so as to rotate the second wheel  68  to display the number 2 in an aperture. 
         [0064]    In order to actuate the actuating organ  22  relative to function no.  2 , the user pulls the stem  2  toward the outside of the movement such that, as described above, the support  24  slides relative to the base  25 , toward the actuating organ  22 . In that movement, the pin  27  slides in the opening  30  of the pivoting base  25  and becomes housed at the bottom of the second track  34  of the base  32  of the safety device. The pins  27  and  29  being in the axis of the second track  34 , the movement of the actuating device  4  is a simple linear movement. The actuating device  4  is then in actuating position no.  2 , the wheel  26 , carried by the support  24 , then being able to mesh with said actuating organ  22  as shown in  FIG. 6 . Function no.  2  is actuated by rotating the winding crown, which drives the rotation of the clutch-pinion  14 , and therefore of the intermediate wheel  28  and the wheel  26 . 
         [0065]    The support  24  is kept in actuating position no.  2  by the safety device using the pin  27  housed at the bottom of the track of the base  32 . 
         [0066]    Pressing the winding stem  2  in the direction of the movement causes reverse sliding of the support  24 , such that the wheel  26  is extricated from the actuating organ  22 , the mechanism returning to selecting position no.  2  shown in  FIG. 5 . 
         [0067]    In reference to  FIGS. 7 and 8 , when the user wishes to select function no.  3 , he presses on the push-piece  52  so as to pivot the lever  54 , which once again causes the selector organ  50  and the cam  58  to rotate by 45° in the clockwise direction. The feeler-spindle  60  pivots while driving the rotation of the pivoting base  25 , which enters selecting position no.  3  shown in  FIG. 7 . In that same movement, the support  24  of the actuating device pivots with the base  25  so as also to reach selecting position no.  3  shown in  FIG. 7 , the wheel  26  being located facing the actuating organ  23  for function no.  3 . 
         [0068]    Also in that same movement, the first toothed wheel  66  of the indicator mechanism for the selected function  10  pivots and meshes with the intermediate wheel  70  so as to rotate the second wheel  68  to display the number 3 in an aperture. 
         [0069]    In order to actuate the actuating organ  23  relative to function no.  3 , the user pulls the stem  2  toward the outside of the movement so that, as described above, the support  24  slides relative to the base  25 , toward the actuating organ  23 . In that movement, the pin  27  slides in the opening  30  of the pivoting base  25  and becomes housed at the bottom of the third track  34  of the base  32  of the safety device. The actuating device  4  is then in actuating position no.  3 , the wheel  26 , supported by the support  24 , then being able to mesh with said actuating organ  23  as shown in  FIG. 8 . Function no.  3  is actuated by rotating the winding crown, which drives the rotation of the clutch-pinion  14 , and therefore of the intermediate wheel  28  and the wheel  26 . 
         [0070]    The support  24  is kept in actuating position no.  3  by the safety device using the pin  27  housed in the bottom of the track of the base  32 . 
         [0071]    Pressing the winding stem  2  toward the movement drives the reverse sliding of the support  24 , such that the wheel  26  is extricated from the actuating organ  23 , the mechanism returning to selecting position no.  3  shown in  FIG. 7 . 
         [0072]    Pressing the push-piece  52  again causes the lever  54  to pivot, which once again causes the selector organ  50  and the cam  58  to rotate by 45° in the clockwise direction. The mechanism is then returned to selecting position no.  2 . 
         [0073]    The mechanism according to the present invention has the advantage of being bidirectional. 
         [0074]    Of course, the present invention is not limited to the embodiment described above. In particular, the number of functions to be selected and actuated is not limited to three. In fact, it suffices to adapt the travel of the actuating device during its various rotations to enter selecting positions, in the number of actuating organs to be selected. Likewise, the rotation direction of the selector organ  50  and the cam  58  can be opposite the directions indicated in the described variant, by making the necessary modifications within the reach of one skilled in the art. 
         [0075]    Another alternative embodiment making it possible to increase the number of functions to be selected and actuated is shown in  FIG. 9 . In this variant of the invention, a carriage  80  is also provided mounted pivoting on the frame. The primary actuating organs  21 ,  22 ,  23  are mounted pivoting on said carriage  80 . To avoid overloading  FIG. 9 , only the primary actuating organs  21  and  23  are shown. An actuating mechanism (not shown) is also provided that is arranged to pivot the carriage  80 . Such a mechanism is for example a push-piece or a trigger. The carriage  80  can for example be arranged to occupy two positions, such that each primary actuating organ  21 ,  22 ,  23  can also occupy two actuating positions. Also provided are secondary actuating organs arranged to actuate the selected function, each being kinematically connected to the mechanism corresponding to said selected function. Furthermore, the secondary actuating organs are arranged to be actuated by the primary actuating organs when the latter are located facing the secondary actuating organs. In  FIG. 9 , only the secondary actuating organs  81 ,  82 ,  83 ,  84  are shown. The secondary actuating organs  81  and  82  are arranged to cooperate with the primary actuating organ  21  and the secondary actuating organs  83  and  84  are arranged to cooperate with the primary actuating organ  23 . Thus, when the carriage  80  is located in the position shown in solid lines in  FIG. 9 , the primary actuating organ  21  can actuate the secondary actuating organ  82  and the primary actuating organ  23  can actuate the secondary actuating organ  84 , based on the position of the actuating device  4 . When the carriage  80  is moved by a user and located in the position shown in dotted lines in  FIG. 9 , the primary actuating organ  21  can actuate the secondary actuating organ  81  and the primary actuating organ  23  can actuate the secondary actuating organ  83 , based on the position of the actuating device  4 . As a result, in the configuration with three primary actuating organs each able occupy two actuating positions, it is possible to actuate six secondary actuating organs, corresponding to six functions using only a winding crown with a push-piece and a control organ of the actuating mechanism of the carriage  80 . 
         [0076]    Another alternative embodiment making it possible to increase the number of functions to be selected and actuated is to provide tracks on the support, the shape of said tracks being chosen to allow dual positioning of the support, and therefore of the actuating device. 
         [0077]    Another alternative embodiment making it possible to increase the number of functions to be selected and actuated is to provide a carriage similar to the carriage  80  bearing the primary actuating organs, but moving not in an arc of circle as shown in  FIG. 9 , but in translation in front of the secondary actuating organs. Also provided is an actuating mechanism arranged to move that carriage. In that case, the center distances between the actuating wheel  26  and each of the primary actuating organs  21 ,  22  and  23  must be adapted so as to offset the difference in penetration depth between the actuating wheel  26  and either of the primary actuating organs  21 ,  22 ,  23 . It is possible, for example, to provide a mechanism connected to the carriage that would make it possible to act on the movement of the lever  18 , so that it moves by a different distance toward the inside of the movement depending on the position of carriage. 
         [0078]    The shape of the cam and the choice of the functions to be selected and actuated may also be modified without going beyond the scope of the present invention. Furthermore, the mechanism can be adapted so that the selector organ  50  rotates in the counterclockwise direction, the clockwise direction corresponding to the alternative described here.
