[Technical Field]

[0001] The present invention relates to a pull-out piece indexing device. The present invention also relates to a pull-out piece including said device. The present invention also relates to a mechanism including said device or said pull-out piece. The present invention also relates to a movement including said mechanism, said device, or said pull-out piece.

The present invention further relates to a method for assembling said timepiece, said movement, said mechanism, said device, or said pull-out piece. [Background technology]

[0002] Patent document 1 discloses a mechanism including a control rod that can be positioned in two axial positions. To this end, a beak formed on one end of an extraction piece spring cooperates with a pin fixedly joined to the extraction piece. More specifically, to define a first axial rod position, a first side of the beak of the extraction piece spring abuts against the extraction piece pin, and to define a second axial rod position, a second side of the beak can move under the pulling effect of the rod and abut against the same extraction piece pin. In this mechanism, the extraction piece spring is integral with the mechanism rocker, and the beak is integral with the extraction piece spring.

[0003] The patent application WO 02 / 047634 discloses a mechanism including a control rod that can be positioned in three axial positions. To this end, a beak formed at one end of an extraction leaf spring cooperates with a spring pin. In this case, the beak has the particular feature of including a cavity interposed between the two beak sides that define the rod's most distal position, in order to define an intermediate rod position. Like the extraction leaf spring of the mechanism of the patent application WO 02 / 047634, the beak is also integral with the extraction leaf spring.

[0004] Patent document 3 discloses a mechanism including an alternative extraction piece device. In a first embodiment of the extraction piece device, the extraction piece spring is in the form of a single piece. The extraction piece spring includes a leaf spring and a beak, which is pivoted against the toothed flank of the extraction piece under the action of the leaf spring. In an alternative embodiment of the extraction piece device, the beak is in the form of a single piece that is articulated to the frame of the movement, interposed between the extraction piece spring and the extraction piece.

[0005] Finally, Patent Document 4 relates to a mechanism including a control rod formed from a pull-out piece spring with a beak and a pull-out piece with a pin, which can assume two or three axial positions depending on the configuration of the pull-out piece device. In a first configuration of the beak of the pull-out piece spring relative to the pull-out piece pin, the back surface of the beak, which is formed with two different sides, abuts against the pull-out piece pin, so that the pull-out piece device can define two axial positions for the control rod. In a second configuration of the beak of the pull-out piece relative to the pull-out piece pin, the front surface of the beak, which is formed with a first side, a cavity, and a second side, abuts against the pull-out piece pin, so that the pull-out piece device can define three axial positions for the control rod. In this case, the beak is integral with the pull-out piece spring. Such a mechanism has the advantage of streamlining the number of parts required to define a mechanism with two or three positions. However, the extraction spring is preloaded in two different ways depending on the configuration of its beak relative to the extraction pin, which can result in different forces on the rod. Furthermore, there is a risk of watchmakers making an assembly error during the assembly or restoration of the movement involving the mechanism. [Prior art documents] [Patent documents]

DETAILED DESCRIPTION OF THE INVENTION

[0017] A first embodiment of a watch 1000 is described below with reference to FIGS.

[0018] The timepiece 1000 is, for example, a small timepiece, in particular a wristwatch.

[0019] The watch 1000 includes a miniature watch movement 700 that is intended to be mounted within a watch case to protect it from the external environment.

[0020] The miniature watch movement 700 may be an electronic or mechanical movement, and in particular an automatic movement.

[0021] The miniature clock movement 700 includes a miniature clock mechanism 600. In particular, the miniature clock mechanism may be a mechanism that uses a pull-out piece device. The miniature clock mechanism includes a pull-out piece indexing device 100 and a frame 99 that includes a movement blank. The term "indexing of the pull-out piece" is intended to be understood as indicating the definition of various stable positions of the pull-out piece. These stable positions are separated by a continuum of unstable intermediate positions. The user moves the pull-out piece from one stable position to another stable position through the continuum of unstable intermediate positions through mechanical action, specifically mechanical action on the rod. Between two stable positions or two indexed positions, the pull-out piece moves transitionally through the continuum of unstable intermediate positions.

[0022] The indexing device 100 may in particular comprise a lever device for the extraction piece or an extraction piece lever / spring device. In a first embodiment, the indexing device comprises a lever / spring device 2 for the extraction piece 10.

[0023] The pull-out piece 10 engages, in particular via one of its ends, in a groove of the first control rod 5. The pull-out piece controls, in particular via its other end, a rocker 6 which engages in a groove of the sliding pinion 7. In this way, the pull-out piece 10 makes it possible to control, at least indirectly, the position of the sliding pinion. The position of the pull-out piece is indexed by means of an indexing device provided for this purpose.

[0024] The pull-out piece 10 is pivoted on the frame 99 along an axis A1. The mechanism 600 also includes a spring 97 which presses the pull-out piece 10 against the frame, and in particular against the movement blank 99 of the mechanism 600.

[0025] The control rod 5 is part of the mechanism 600. The control rod 5 is translatable in a plane P perpendicular or substantially perpendicular to the extraction piece axis A1, in a direction D. The rod 5 customarily cooperates with the extraction piece 10 by means of an extraction piece pin 11 engaged in a groove 51 in the rod 5. In this state, a translational movement of the rod 5 in the plane P, in the direction D, results in a rotational movement of the extraction piece 10 about the axis A1.

[0026] The mechanism 600 also includes an extraction piece lever / spring device 2. An extraction piece 10 is also provided to cooperate with the lever / spring device 2 to form an extraction piece indexing device 100, in order to be able to define the axial position of the rod 5. In other words, the indexing device also includes the extraction piece.

[0027] The term "axial position" of the rod 5 or sliding pinion 7 is intended to be understood to indicate a specific position of the rod 5 or sliding pinion 7 relative to the movement 700 along the axis D after movement of the rod 5 in the direction D within the plane P.

[0028] The puller piece 10 is also provided for cooperating with a mechanism rocker 6, pivoted about an axis A6 and resiliently returned by a spring 98, in order to control the axial position of the sliding pinion 7. The sliding pinion is, for example, arranged on a second rod 8, which is, for example, parallel or substantially parallel to the first rod 5. Thus, the rocker 6 engages in a groove 71 of the pinion 7. The pinion 7 also comprises first and second tooth rows 72, 73, which, according to the axial direction of the first rod 5, can engage with a specific control chain of the mechanism 600.

[0029] The kinematics of the sliding pinion 7 are compatible with those of the sliding pinion of the mechanism described in US Pat. No. 5,649,999. In a first axial position P1 of the first rod 5 and / or sliding pinion 7, the toothings 72, 73 are outside the range of the gears involved in the various control chains of the mechanism. In a potential intermediate position P2 of the first rod 5 and / or sliding pinion 7, the end toothing 72 of the sliding pinion 7 engages with the toothing of the wheel 20 of the first control chain 200 of the time display or time derivative, in particular the calendar display, such as the date display. In the third position P3 of the first rod 5 and / or sliding pinion 7, the front toothing 73 of the sliding pinion 7 engages with the toothing of the pinion 30 of the second control chain 300 for displaying or derivative time, in particular for setting the time of the movement 700.

[0030] Furthermore, the sliding pinion 7 can be rotationally driven under the action of rotation of the first rod 5 via a pinion 9 mounted directly on the first rod 5, which in this case engages with the end toothing 72 of the sliding pinion 7. In this manner, the sliding pinion 7 is kinematically coupled to the first rod 5 in translation in direction S via the pull-out piece 10, the rocker 6 and its return spring 98, or in rotation via the pinion 9.

[0031] The mechanism 600 also includes a kinematic chain 500 for winding the movement 700. The kinematic chain includes a pinion 55 mounted directly on the first rod 5 and engaging a first crown wheel 56. The first crown wheel 56 can be moved into engagement with a second crown wheel 57 depending on the state of a vertical coupling controlled by the movement of the first rod 5 in direction D.

[0032] The coupling device is comparable to that described in patent document 2. In particular, the coupling device comprises a third rod 58 arranged perpendicular or substantially perpendicular to the first rod 5 and fixedly joined to a second crown wheel 57. The first rod 5 controls the third rod 58 by means of a groove 52 machined in it. In a first axial position P1 of the first rod 5, the end of the third rod 58 is located at the base of the groove 52 of the first rod 5, so that under the action of the return spring 96, the Breguet teeth of the second crown wheel 57 engage with the Breguet teeth of the first crown wheel 56. In this manner, in the first axial position P1 of the first rod 5, the kinematic winding chain of the movement 700 is engaged. The outward movement of the movement 700 from position P1 of the rod 5 in direction D raises the third rod 58 from the base of the groove 52 of the first rod 5, so that the Breguet teeth of the second crown wheel 57 are outside the range of the Breguet teeth of the first crown wheel 56. In this manner, at positions P2, P3 of the first rod 5, the winding kinematic chain of the movement 700 is released.

[0033] The indexing device 100, and in particular the lever / spring device 2, - an indexing member 4; an indexing element 3, comprising at least two pairs of side faces 31a, 31b, 31c; 32a, 32b for defining an indexing position of the pull-out piece, and mounted on the indexing member 4; Includes:

[0034] The indexing member 4 and the indexing element 3 are arranged or configured to define at least two positions, in particular at least two fixed positions, of the indexing element 3 on the indexing member 4. This means that the indexing element can be positioned on the indexing member in the following manner: into a first configuration or position for defining a first set of indexed positions of the pull-out piece corresponding to a first set of indexed positions of the rod and / or a first set of indexed positions of the rocker after the indexing device is integrated into the mechanism 600, or in a second configuration or position for defining a second set of indexed positions of the pull-out piece, which corresponds to a second set of indexed positions of the rod and / or a second set of indexed positions of the rocker, after the indexing device has been integrated into the mechanism 600; This is because it can be installed.

[0035] In these first and second configurations, the indexing member and the indexing element are preferably fixedly joined to each other, fixed to each other, or fully connected to each other. The connection may also be one that allows some degree of freedom between the indexing member and the indexing element, as long as that degree of freedom does not impair the indexing function. For example, the indexing element may be free to move perpendicular to plane P relative to the indexing member. The mechanical connection is formed during assembly of the mechanism or timepiece. This connection is preferably not disassembled during the normal or conventional operating mode of the timepiece. The connection is preferably only disassembled during any potential after-sales service operations. In this embodiment, the indexing element is kinematically connected to the indexing member during handling of the first rod, in particular during movement of the first rod in direction D (in particular, the indexing element and the indexing member are fixed to each other with respect to rotational movement about an axis perpendicular to plane P and translational movement along an axis parallel to plane P).

[0036] In the embodiment of mechanism 600 described below, lever / spring device 2 includes an indexing member 4 and an indexing element 3. Indexing member 4 is a lever / spring member 4. Said member is made up of a first rigid portion 41, a first end of which is articulated relative to frame 99 along axis A41. Lever / spring member also includes a second resilient portion 42, a first end of which is articulated relative to frame 99 along axis A42. First and second portions 41, 42 are connected to each other in the region of their respective second ends. More specifically, second portion 42 is in the form of a curved plate formed as a continuation of first rigid portion 41. Lever / spring member generally has the form of an open loop, with axes A41, A42 located close to each other.

[0037] The second elastic portion 42 constitutes a return element which returns the indexing element and / or indexing member to the cooperating configuration with the pull-out piece 10 .

[0038] In this case, the indexing element 3 is in the form of a plate or cam which is fixed to the member 4, in particular to the first rigid part 41 of the member 4 of the lever / spring device 2, in a position selected from at least two possible positions.

[0039] For this purpose, the indexing element 3 is preferably mounted so as to be displaceable on the indexing member 4, in particular so as to be rotationally displaceable on the indexing member about the axis A. For this purpose, the indexing device advantageously comprises positioning elements 43, 33a, 33b, such as pins cooperating with holes, for positioning, in particular fixing, the indexing element 3 in a position selected from at least two positions relative to the indexing member 4.

[0040] To this end, the spring lever member 4 is provided with a pin 43 fixedly joined to the first portion 41 for insertion into a notch selected from notches 33a and 33b of the cam 3 in order to index the cam 3 into position relative in particular to the first portion 41 of the lever / spring member 4. Alternatively, of course, the pin may be fixedly joined to the cam 3 and the notch formed on the lever / spring member 4.

[0041] In this embodiment, the lever / spring device 2 is in the form of an assembly including a lever / spring member 4 and a cam 3 indexed and fixed to the member 4 , in particular to a first rigid portion 41 of the member 4 .

[0042] The cam 3 comprises a first functional surface 31 and a second functional surface 32, one or the other of which is provided to cooperate with the first pawl 12 of the pull-out piece 10 depending on the position of the cam 3 on the lever / spring member 4.

[0043] Cooperation of the first notch 33a and the pin 43 makes it possible to define a first position of the cam 3 on the lever / spring element 4. After the lever / spring device 2 is assembled, the cam 3 is firmly fixed to the portion 41 of the lever / spring element 4, for example by means of the pin 44. Such assembly of the lever / spring element 2 may occur upstream of the assembly of the movement 700, in particular of the mechanism 600. Alternatively, the cam 3 may simply be angularly indexed onto the element 4 of the lever / spring element 2 by the pin 43 and vertically separated by the element 4 and the movement blank 99 of the movement 700. In this manner, assembly of the cam 3 onto the lever / spring element 4 may be performed during the assembly of the movement 700, in particular of the mechanism 600. The indexing element may also be hammered into the indexing element 4.

[0044] In this first configuration of the lever / spring device 2, a first surface 31 of the cam 3 is capable of cooperating with the extraction piece, for example with the first claw 12 of the extraction piece 10. This surface 31 comprises three flanks 31a, 31b, 31c which, in cooperation with the claw 12, are capable of defining three positions of the extraction piece, in particular three angular, stable or indexed positions. These stable or indexed positions of the extraction piece are: three different axial positions of the first rod 5, which are stable or indexed positions, in this case positions P1, P2 and P3 of the first rod 5, and / or - three different angular positions of rocker 6, which are stable or indexed positions, can be defined.

[0045] In the first position P1, the first flank 31a of the cam 3 abuts the first pawl 12 of the pull-out piece 10 under the action of the second elastic part 42 of the lever / spring element 4, which results in the pull-out piece 10 abutting against the abutment surface 99a of the movement blank 99 of the mechanism 600, as shown in Figure 5. In this first position P1, the toothing 72, 73 of the sliding pinion 7 is outside the range of the gears involved in the various control chains of the mechanism as a result of the positioning of the rocker 6, in which one end 61 of the rocker 6 abuts against the stop surface 13 of the pull-out piece under the action of the spring 98. Furthermore, in this first position P1, the winding chain 500 is engaged.

[0046] Pulling of the first rod 5 from position P1 in direction D toward the outside of the movement 700 results in counterclockwise rotation of the pull-out piece 10. The first pawl 12 then acts against the first surface 31 of the cam 3, and therefore against the lever / spring element 4, until it is positioned in the recess formed by the second lateral surface 31b, as shown in FIG. 6. In this second position P2, the rocker 6, under the action of the spring 98, pivots toward the outside of the movement 700 (counterclockwise) so that the end toothing 72 of the sliding pinion 7 can mesh with the toothing of the wheel 20 of the first control chain 200 for the time display or a time derivative, in particular a calendar display such as a date display. In this second position P2, the end 61 of the rocker is no longer in contact with the pull-out piece 10. Furthermore, the winding chain 500 is released.

[0047] Further pulling of the first rod 5 from position P2 in direction D towards the outside of the movement 700 again results in a counterclockwise rotation of the extractor piece 10. The first pawl 12 acts against the first surface 31 of the cam 3, and therefore against the lever / spring element 4, until it is positioned against the third side surface 31c, as shown in Figure 7. During this rotation, the extractor piece acts on the end 61 of the rocker 6 by means of the second pawl 14, in order to drive the rocker 6 towards the inside of the movement 700 (counterclockwise), against the spring 98, so that the front toothing 73 of the sliding pinion 7 engages with the pinion 30 of the second control chain 300 for displaying or deriving the time, in particular for setting the time of the movement 700.

[0048] The cooperation of the second notch 33 b with the pin 43 allows the definition of a second position of the cam 3 on the member 4 of the lever / spring device 2 .

[0049] In the second configuration of the lever / spring device 2, a second surface 32 of the cam 3 can cooperate with the extraction piece 10, in particular with the first pawl 12 of the extraction piece 10. The surface 32 comprises two lateral sides 32a, 32b that make it possible to define two different axial positions of the first rod 5, in this case positions P1 and P3 of the first rod 5. These positions P1 and P3 of the first rod 5 are, for example, identical to those described above.

[0050] In first position P1, the first flank 32a of the cam 3 abuts the first pawl 12 of the extraction piece 10 under the action of the second elastic part 42 of the lever / spring element 4, which causes the extraction piece 10 to abut against the stop face 99a of the movement blank 99 of the mechanism 600, as shown in Figure 8. In this first position P1, the toothing 72, 73 of the sliding pinion 7 is outside the range of the gears involved in the various control chains of the mechanism as a result of the positioning of the rocker 6, whose end 61 abuts against the stop face 13 of the extraction piece under the action of the spring 98. Furthermore, in this first position P1, the winding chain 500 is engaged.

[0051] Pulling of the first rod 5 from position P1 in direction D towards the outside of the movement 700 causes the extraction piece to rotate counterclockwise. The first pawl 12 therefore acts against the second surface 32 of the cam 3, and thus against the lever / spring member 4, until it is positioned against the second side 32b, as shown in Figure 9.

[0052] During this rotation, the extractor acts on the end 61 of the rocker 6 by means of the second pawl 14 to drive the rocker 6 towards the inside of the movement 700, against the spring 98, so that the front toothing 73 of the sliding pinion 7 engages with the pinion 30 of the second control chain 300 for displaying or derivatizing the time, in particular for setting the time of the movement 700.

[0053] The angular amplitude of movement of the extraction piece 10 between rod positions P1 and P3 when the lever / spring device 2 is in said second configuration corresponds in this case to the sum of the angular amplitudes of movement of the extraction piece between positions P1 and P2 and between positions P2 and P3 when the lever / spring device 2 is in the first configuration. Similarly, the amplitude of movement of the first rod 5 between positions P1 and P3 when the lever / spring device 2 is in the second configuration corresponds in this case to the sum of the amplitudes of movement of the first rod 5 between positions P1 and P2 and between positions P2 and P3 when the lever / spring device 2 is in the first configuration.

[0054] As described above, a first configuration or position of the indexing element on the indexing member allows for the definition of three pull-out piece positions relative to the frame 99, and a second configuration or position of the indexing element on the indexing member allows for the definition of two pull-out piece positions relative to the frame 99.

[0055] In a variant of the first embodiment, not shown, the lever / spring arrangement may be replaced by an assembly comprising a lever arrangement and a return element, the latter being manufactured as two separate parts, the return element returning the lever arrangement against the pull-out piece. - an indexing element formed by the actual lever, and - an indexing element including at least two pairs of sides for defining an indexing position of the pull-out piece and mounted on the indexing member; Includes:

[0056] A second embodiment of the watch 1000 is described below with reference to Figures 10 to 17.

[0057] The timepiece 1000 is, for example, a small timepiece, in particular a wristwatch.

[0058] The watch 1000 includes a miniature watch movement 700 that is intended to be mounted within a watch case to protect it from the external environment.

[0059] The miniature watch movement 700 may be an electronic or mechanical movement, and in particular an automatic movement.

[0060] The clock movement 700 includes a clock mechanism 600. In particular, the clock mechanism may be a mechanism that uses a pull-out piece device. The clock mechanism includes a pull-out piece indexing device 100′ and a frame 99. The term “indexing of the pull-out piece device” is intended to be understood as indicating the definition of various stable positions of the pull-out piece device. These stable positions are separated by a continuum of unstable intermediate positions. A user moves the pull-out piece device from one stable position to another stable position through the continuum of unstable intermediate positions through mechanical action, specifically mechanical action on the rod. Between two stable positions or two indexed positions, the pull-out piece device moves transitionally through the continuum of unstable intermediate positions.

[0061] In the second embodiment, the indexing device 100' includes a pull-off piece device 10'. The pull-off piece indexing device preferably also includes a return element, such as a lever and a spring. The return element and lever may be constituted by a spring lever 2' including a return element 42', as shown in Figures 10 and 13 to 17.

[0062] The indexing device, in particular the pull-out piece device, - an indexing member 1', and an indexing element 3' comprising at least two pairs of side faces 31a', 31b', 31c'; 32a', 32b' for defining the indexing position of the pull-out piece and mounted on the indexing member 1'; Includes:

[0063] Preferably, the second embodiment of the timepiece differs from the first embodiment of the timepiece only with regard to the position of the indexing element and the indexing member. In the first embodiment, the indexing element is mounted on a lever or spring lever that constitutes the indexing member, and the indexing element cooperates with a pawl provided on the pull-out piece. In the second embodiment of the timepiece, the situation is reversed, i.e. the indexing element is mounted on a member 1' of the pull-out piece device 10', the member 1' constituting the indexing member; and The indexing element cooperates with a pawl provided on a lever or spring lever.

[0064] The indexing member 1' and the indexing element 3' of the pull-out piece 10' are arranged or configured to define at least two positions, in particular at least two fixed positions, of the indexing element 3' on the indexing member 1'. This is because the indexing element is into a first configuration or position for defining a first set of indexed positions of the pull-off piece device corresponding to a first set of indexed positions of the rod and / or a first set of indexed positions of the rocker after the indexing device is integrated into the mechanism 600; or in a second configuration or position for defining a second set of indexed positions of the pull-off piece device, which corresponds to a second set of indexed positions of the rod and / or a second set of indexed positions of the rocker, after the indexing device is integrated into the mechanism 600; This is because it can be installed.

[0065] In these first and second configurations, the indexing member and the indexing element are preferably fixedly joined to each other, fixed to each other, or completely connected to each other. The connection may also be one that allows some degree of freedom between the indexing member and the indexing element, as long as that degree of freedom does not impair the indexing function. For example, the indexing element may be free to move perpendicular to plane P relative to the indexing member. The mechanical connection is formed during assembly of the mechanism or timepiece. This connection is preferably not disassembled during the normal or conventional operating mode of use of the timepiece. The connection is preferably only disassembled as needed during potential after-sales servicing operations. In this embodiment, the indexing element is kinematically connected to the indexing member or pull-out piece member during handling of the first rod, in particular during movement of the first rod in direction D (in particular, the indexing element and the indexing member are fixed to each other with respect to rotational movement about an axis perpendicular to plane P and translational movement along an axis parallel to plane P).

[0066] In the embodiment of mechanism 600 described below, the pull-off piece device 10' serving as the pull-off piece includes an indexing member 1' and an indexing means 3'. The indexing member 1' is a member 1' of the pull-off piece device. The member 1' (or pull-off piece member 1') of this pull-off piece device 10' is articulated relative to the frame 99 along an axis A1.

[0067] In this case, the indexing element 3' is in the form of a plate or cam which is fixed to the member 1' in a position selected from at least two possible positions.

[0068] For this purpose, the indexing element 3' is preferably mounted so as to be displaceable on the indexing member 1', in particular so as to be rotationally displaceable on the indexing member about the axis A'. For this purpose, the indexing device advantageously comprises positioning elements 13', 33a', 33b', such as pins cooperating with holes, for positioning, in particular fixing, the indexing element 3' in a position selected from at least two positions relative to the indexing member 1'.

[0069] For example, a pin 13' fixedly joined to the member 1' is provided for insertion into a selected one of the notches 33a' and 33b' in the cam 3' to index the cam 3' into position relative to the member 1'. Alternatively, of course, the pin may be fixedly joined to the cam 3' and the notch may be formed on the member 1'.

[0070] In this embodiment, the pull-off piece device 10' may be in the form of an assembly including a pull-off piece member 1' and a cam 3' indexed and fixed relative to the pull-off piece member 1'.

[0071] The cam 3' comprises a first functional surface 31' and a second functional surface 32', one or the other of which two surfaces is provided for cooperating with a first pawl 12' of the lever or spring lever 2' depending on the position of the cam 3' on the pull-out piece member 1'.

[0072] The cooperation of the first notch 33a' and the pin 13' makes it possible to define a first position of the cam 3' on the pull-out piece member 1'. After the pull-out piece device 10' is assembled, the cam 3' is firmly fixed to the member 1', for example by means of the pin 14'. The assembly of such a pull-out piece device may take place upstream of the assembly of the movement 700, in particular of the mechanism 600. Alternatively, the cam 3' may simply be angularly indexed onto the member 1' by the pin 13' and vertically separated by the member 1' and the movement blank 99 of the movement 700. In this manner, the assembly of the cam 3' on the member 1' may be carried out during the assembly of the movement 700, in particular of the mechanism 600. The indexing element 3' may also be driven into the pull-out piece member 1'.

[0073] In this first configuration of the pull-off piece device 10', a first surface 31' of the cam 3' is capable of cooperating with the lever 2', for example with the pawl 12' of the lever. This surface 31' comprises three side surfaces 31a', 31b', 31c' which, in cooperation with the pawl 12', can define three stable or indexed angular positions of the pull-off piece device 10'. These stable or indexed angular positions of the pull-off piece device 10' are: three different axial positions of the first rod 5, which are stable or indexed positions, in this case positions P1, P2 and P3 of the first rod 5, and / or - three different angular positions of rocker 6, which are stable or indexed positions, can be defined.

[0074] The cooperation of the second notch 33b' with the pin 13' allows the definition of a second position of the cam 3' on the pull-out piece member 1'.

[0075] In the second configuration of the pull-out piece device 10', a second surface 32' of the cam 3' can cooperate with the lever 2', in particular with the first pawl 12' of the lever 2'. The surface 32' comprises two lateral sides 32a', 32b' that make it possible to define two different axial positions of the first rod 5, in this case positions P1 and P3 of the first rod 5. These positions P1 and P3 of the first rod 5 are, for example, identical to those described above.

[0076] As described above, a first configuration or position of the indexing element on the indexing member allows for the definition of three pull-out piece positions relative to the frame 99, and a second configuration or position of the indexing element on the indexing member allows for the definition of two pull-out piece positions relative to the frame 99.

[0077] In this second embodiment, the indexing device comprises a return element, for example constituted by a spring or a spring portion 42' of the spring lever 2', which returns the indexing element 3' to a cooperating configuration with the spring lever 2'.

[0078] In the described embodiments, the indexing element is fixed or attached to the pull-out piece member or the lever member or the spring lever member. In alternative embodiments of the pull-out piece indexing device, the indexing element may be indexed or fixed or attached to an intermediate element located at the interface between the lever or spring lever and the pull-out piece.

[0079] Of course, depending on the embodiment of the extraction piece device, the spring lever may more simply be in the form of a spring. The extraction piece claw may also be replaced by a pin, if desired.

[0080] In the above-described embodiments and variants, position P1 corresponds to a position for winding the movement 700. Alternatively, whatever the embodiment and variant, the various positions P1 may correspond to different clock functions.

[0081] In the above-described embodiments and variations, depending on the configuration of the indexing elements, the indexing device allows for the creation of two or three index positions of the pull-out piece. Of course, such indexing devices may be modified to allow for more than two configurations of indexing elements on the indexing member. For example, the indexing elements may have three or more surfaces, which allows for the definition of an equal number of sets of pull-out piece index positions. Similarly, each surface may define one, two, three, or four (or more) index positions. Furthermore, a first surface may define n first index positions, and a second surface may define n second index positions, where the first and second index positions are different from each other, or one of the first positions may be different from both positions, where n is a natural integer. Finally, a first surface may define n first index positions, and a second surface may define m second index positions, where n and m are natural integers, and n is different from m.

[0082] Whatever the embodiment or variant, the indexing element 3;3' may be separated on the one hand by the indexing member 4;1' and on the other hand by the frame 99. Alternatively, whatever the embodiment or variant, the indexing element 3' may be mounted so as to be completely connected to the indexing member 4;1'. For example, the indexing element may be hammered into the indexing member.

[0083] Preferably, whatever the embodiment or variant, - the first indexed pull-off position allows winding of the clock movement, i.e. the first indexed pull-off position defines the configuration and arrangement of the movement parts that connect the first rod to the winding chain of the movement, - the second indexed pull-out position allows for a correction, in particular a rapid correction, of the time-derived function of the clock movement, i.e. the second indexed pull-out position defines the configuration and arrangement of the parts of the movement that connect the first rod to the correction chain of the time-derived function of the clock movement, and - the third indexed pull-out position allows the time of the clock movement to be set, i.e. the third indexed pull-out position defines the configuration and arrangement of the movement parts that connect the first rod to the time-setting chain of the clock movement.

[0084] Preferably, the first pull-out piece position corresponds to a position of the first rod where the rod is pushed deepest into the movement, the second pull-out piece position corresponds to a first stable indexed position of the first rod that is encountered when traction is applied to the first rod in the first position, and the third pull-out piece position corresponds to a first stable indexed position of the first rod that is encountered when traction is applied to the first rod in the second position.

[0085] The present invention further relates to a method for assembling the above-mentioned pull-out piece indexing device 100, 100', or a method for assembling the above-mentioned mechanism 600, or a method for assembling the above-mentioned movement 700, or a method for assembling the above-mentioned timepiece.

[0086] The method is: - providing an indexing member 4;1′, - providing an indexing element 3:3', - Indexing member 4;1' - 1st position, or - 2nd position assembling the indexing element 3:3' to The steps include:

[0087] Of course, if the indexing element has more than two surfaces, the indexing element may alternatively be mounted to a third position on the indexing member.

[0088] As a result of the above-mentioned solutions, the pull-out piece indexing element may be selected and configured upstream of the assembly of the timepiece movement in such a way that the pull-out piece device is able to position the rod of the mechanism with which it is involved in, in particular in two or three positions. As a result of these solutions, in which the pull-out piece indexing element is selected and configured upstream of the assembly of the timepiece movement, the risk of the watchmaker making an assembly error during the assembly of the movement with which the mechanism is involved or during restoration work is eliminated.

[0089] The above solution is advantageously implemented when the construction of a watch movement involves the organization of a family of calibers in order to use, as far as possible, the same parts or assemblies for the movements whose final appearance is adjusted by the addition of elements specific to the desired level of complexity. This allows, for example, a calendar movement and a time zone movement of the same family to share the same basic movement and pull-out piece indexing device with the same parts, these parts, in particular the indexing elements, being configured differently simply to define the indexing positions of the pull-out pieces adapted to the two movements. This allows pull-out piece indexing devices with the same parts to be adapted to very different movements or watches.

[0090] In particular, the solutions described above allow the production of extraction piece devices that are highly configurable, in particular allowing the mechanism to be implemented in two or three positions depending on the number of functions to be modified. These solutions make it possible to maximize the number of parts and assemblies common to movements of the same family.

[0091] In this specification, "indexing member" is intended to be understood to preferably denote a member that supports an indexing element, and in particular a member that supports an indexing cam. [Explanation of symbols]
